DETAILED DESCRIPTION

[0030] A lift system can have a base platform (e.g., base or base membrane) with one or more expandable chambers configured to transition between a collapsed configuration to an expanded configuration to adjust (e.g., lift) bedding such as sheets, blankets, etc. to an elevated position and reduce or eliminate the force or pressure from such bedding on a user. The base and expandable chambers can be positionable between a surface (e.g., a bed) and bedding. An inflation system can be in operable communication with the base and/or expandable chamber to facilitate the transition of each chamber between the collapsed configuration to the expanded configuration.

[0031] FIG. 1 illustrates an example of the lift system 100 having one or more expandable chambers 105 and 106 in operable communication with the base 110. The expandable members 105 and 106 are shown here in an expanded (e.g., inflated) configuration and are in communication with the base via attachment elements 115. In this example, expandable member 106 is positioned proximal to expandable member 105. Expandable member 105 is also shown with a larger volume than expandable member 106. In some examples, each expandable member may provide a different utility for the use of the lift system in an expanded configuration. For example, expandable chamber 105 may be considered a load bearing expandable chamber configured to provide lift and structural support when elevating the bedding while expandable chamber 106 may be configured to be contactable by the user (e.g., the user's feet) and can be configured to accommodate a comfortable interaction with the user.

[0032] In FIG. 2, the base 110 is shown with the expandable chambers removed or in a collapsed configuration. Here, an example of the base 110 has the attachment elements 115 that can facilitate the engagement and communication between the base 110 and the expandable chambers. For example, expandable chambers may be interchangeable relative to the base 110 allowing for a tailored quantity, position, arrangement, etc. of expandable members on the base 110. In some examples, the base may have one or more attachment elements 115. For example, FIG. 2 illustrates four attachment elements 115 on the base 110. However, the number of attachment elements on the base may be one, two, three, four, five, etc. Each expandable chamber may comprise an attachment element corresponding to the attachment element on the base. Some examples of attachment elements may be hook and look material, adhesives, magnets, snap mechanisms, clips, friction engagement, or any style or type of attachment element to support and maintain the position of an expandable member on the base.

[0033] FIG. 3A to 3C illustrate additional examples of the base for a lift system. Referring to FIG. 3A, a base 120 is shown having valves 121 arranged on the base 120. The valves 121 may be arranged in any manner relative to the base and can be configured to engage (e.g., couple to) one or more expandable chambers (not shown). For example, an expandable chamber may have a corresponding valve configured to engage the valve 121 of the base. Each valve may be selectively activated (e.g., actuated) to control the expansion of one or more of the expandable chambers. For example, one or more valves may be selectively actuated based on the expandable chamber selected for expansion. Attachment elements 122 are also illustrated in FIG. 3A. However, each expandable chamber may be coupled to the base via the valve, attachment element, a combination thereof, or an expandable member may be integrated to the base and expandable via a valve between the expandable member and the base. Also shown in FIG. 3A is an example of an inflation system 123. In this example, the inflation system is a pump in operable communication with the base and configured to modulate air pressure of the expandable chambers. Although FIG. 3A illustrates the inflation system 123 coupled to (e.g., integrated with) the base 120, the expansion system can be integrated with a base, external to the base and configured to be coupled therewith, or a combination thereof (e.g., as illustrated in FIG. 4A).

[0034] In FIG. 3B, another example of a base 125 is shown having attachment elements configure to receive and retain an expandable chamber. In some examples, the attachment elements may be configured to facilitate the transmission of air or other medium for the expansion of an expandable chamber positioned thereon.

[0035] FIG. 3C illustrates an example of a base 130 having a plurality of valves 137 positioned thereon with an inflation system comprising a pump 135 positioned external to the base and in fluid (e.g., gas) communication with the base via tubing 138. The tubing 138 may provide a path for the flow of air pressure from the pump 135 to the base 130. A routing system (e.g., manifold) 136 can then transmit the pressurized air from the tubing to the valves 137 of the base 130. For example, when one or more expandable chambers are configured to be expanded (e.g., inflated), the pump 135 can be activated to pump air to the base and one or more valves may be opened to allow the air from the pump to flow through the base to the expandable chamber to be inflated.

[0036] In some examples, the inflation system comprises a manual expansion element configured to expand the chambers manually via a hand crank or other element configured to transition the expandable chambers between an elevated configuration to a collapsed configuration. In such an example, each chamber may be expanded mechanically. In some examples, the inflation system expands each expandable chamber pneumatically. In some examples, the inflation system comprises a mechanical elevation element and a pneumatic inflation element. For example, a mechanical lift system may comprise a device that rotates a gear that drives a lifter bar to expand or elevate the expandable chambers. In some examples, the mechanical lift may comprise an element to push up or collapse a rod that is connected to a lifter bar for expanding the chambers.

[0037] In some examples, an expandable member may comprise a foam inside of the expandable member and configured to expand when a valve of the expandable member is opened. For example, the foam may be compressed in a collapsed state allowing for the deflated configuration of the expandable member. When a valve is opened, the foam may begin to expand creating negative pressure within the expandable member and promoting air to flow from outside of the expandable member to the interior of the expandable member. In this example, the inflation system may comprise the foam on the interior of the expandable member and the expandable member may then be self-inflating.

[0038] In some examples, a base may comprise one or more expandable members integrated therewith, couplable thereto, or a combination thereof. Each expandable member may be positioned or orientated in any manner relative to the base. For example, as illustrated in FIG. 2, the attachment elements are generally linear and spaced apart from one another. The corresponding attachment elements of the expandable members can allow for attachment of the expandable member to the base parallel to the base attachment elements, perpendicular to the base attachment elements, at an angle relative to the base attachment elements, a combination thereof, or each expandable member may be positioned in any manner relative to the base and corresponding attachment elements. FIG. 4A illustrates an example of the cutouts through which expandable chambers 150 and 151 that may be deployed through the base platform. Although shown here as an example of a collapsed configuration, expansion of each expandable chamber can include supplying air to the base and/or expandable chamber causing the expandable chamber to inflate. The expandable chamber may then inflate and expand upward from the base with the material comprising the expandable chamber transitioning from a collapsed configuration (e.g., substantially from within the base) to form the geometric shape of the expandable chamber in an expanded configuration. When the expandable chamber is transitioned back to a collapsed configuration, the excess material of the expandable chamber may be retracted or collapsed back into the base until the base is sufficiently flat and deflated.

[0039] In some examples, a base member may comprise material or other engagement elements configured to retain the position of the base member on a bed. In FIG. 4B, an example of friction strips 160 are shown on the bottom side of the base member 155. The bottom of the base member may be the exterior surface of the base member configured to contact the bed (e.g., mattress, pad, sheet, etc.) and the opposite or top side of the base may comprise the expandable members and be configured to contact a blanket or other bedding laid thereon. Additional examples of engagement elements on the bottom surface or bottom side of the base member may include magnets, weights, friction material (e.g., rubber), straps configured to engage the bed (e.g., wrap around the mattress), or a combination thereof, or any other element configured to promote a placement and position of the base on the bed. In some examples, the base may be configured to receive insertion of weights in sewn-in pouches in order to keep the base membrane firmly flat on the bedsheet and not prone to moving or deformation when one or more air chambers are inflated. In some examples, the engagement elements at the bottom of the base are configured to maintain a static position of the base relative to the bed after the base has been positioned on the bed, initially.

[0040] FIG. 4C illustrates an additional example of the base including one or more magnets or magnetic features 155 positioned in, on or around the base. The illustrated example shows a frame or perimeter configuration of magnets 156 positioned around the base perimeter. The magnetic feature 156 can be configured to engage a corresponding feature of other elements of the bedding elevation system to retain a position of the device (e.g., base) on the bed. FIG. 4C also illustrates additional friction strips 157 that may be positioned on an exterior side of the base. The friction strips 157 can be configured to contact the mattress while the magnets are then oriented towards other components of the elevation system. For example, the base may be positioned on the mattress or bed with the friction strips 157 contacting the mattress surface to maintain a position of the base on the mattress. Then, a sheet or additional bedding may be layered over the top of the base. The magnetic features 156 can then engage another layer of the base member with the expandable members in communication therewith. The friction strips prevent displacement of the based member layer on the mattress, the magnetic features engage the additional base member layer to retain the base member and expandable members in position on the mattress. In any example, the magnetic features may include a single magnet or a plurality of magnets sufficient to engage and retain the remaining parts of the system on the mattress.

[0041] In some examples, the base platform comprises one or more layers of material. In some examples, the base member comprises a reinforced fabric. In some examples, an exterior surface of the base member may be configured to contact a user and may comprise a fabric. The base material can be sufficiently durable to prevent puncture and accommodate the pressure associated with inflation of the expandable chambers. For example, a base platform may comprise a rip-stop nylon material such as recycled 20 D ripstop polyester or nylon material, or a combination thereof. The material of the lift system may be configured to be antimicrobial, to prevent formation of mold or mildew, and facilitate the operation (e.g., expansion) of the expandable chambers. In some examples, the top of the base membrane can include two compartments: a primary (rearward) compartment through which the blanket-lifting air chamber may protrude and a forward compartment through which the optional footrest or foot-stabilizing air chamber may protrude. Each compartment or cutout may have durable reinforced sewing or stitching along the edges so that the protruding air chambers do not get scratched, popped or worn down from sharp edges 150 and 151. See FIG. 4A. The top of the base membrane in all the embodiments will feature Velcro attachment points (shown in the corners of FIG. 4) for a removable, washable soft fabric cover that will not snag with the top or flat bed sheet or otherwise show protrusions, etc. when the base membrane is retracted or deflated.

[0042] In some examples, the base member may comprise a layer, such as a layer illustrated in FIGS. 4A to 4C configured to communicate with a second base layer, such as those illustrated in FIG. 3A to 3C. For example, the first base layer illustrated in FIG. 4C may be positioned on a mattress, under bedding (e.g., a sheet), then magnetically engaged with a second base layer (e.g., those illustrated in FIG. 3A to 3C, where the first base layer maintains the position of the system on the bed, and the second layer communicates directly with the expandable members as described herein. In any example, when the expandable members are in a retracted or compressed state the base member and retracted expandable members may not be visible under a blanket of bedding covering the device. For example, in a retracted state, the layers and expandable members may be sufficiently retracted and flat under the bedding (e.g., blanket) where they are unnoticeable or not identifiable under a blanket.

[0043] The base may be configured to receive one or more expandable members within one or more layers of the base member. For example, the base member may have an opening in an exterior layer to accommodate the insertion and subsequent expansion of an expandable member.

[0044] In some examples, the base member is configured to lie on top of the foot-end of the bottom fitted bed sheet. In some examples, the base member may comprise straps which can wrap around the mattress to support the position and retention of the system once it has been placed. For example, with adjustable bed frames, the straps may be beneficial to support the placement and position of the base member when the adjustable bed frame transitions through various positions.

[0045] In some examples, the top of the base member can include compartments such as a primary (rearward) compartment through which an expandable chamber can protrude and a forward compartment through which another expandable chamber can protrude. Each compartment or cutout can have durable reinforced sewing or stitching along the edges so that the protruding air chambers do not get scratched, popped or worn down from sharp edges.

[0046] In some examples, a base member may have dimensions configured to accommodate the lifting of bedding for a single person. For example, the base member may be wide enough to lift bedding for a single user (e.g., may be wide enough to lift bedding near the feet of a single user). In some examples, a base member may be configured to lift bedding for more than one user. For example, the base member may be sufficiently wide to accommodate lifting of bedding for two or more people sleeping side-by-side. In some examples, the base member may be sufficiently long to lift bedding beyond the user's feet. For example, the base member may positionable at or near the foot portion of a bed and be configured to lift the bedding from the user's feet to the end of the bed. In some examples, the base member may be any length from a foot portion or end of the bed to a head portion of the bed. For example, the base member may extend along the entire length of the bed such that a user sleeps on the base member and one or more expansion members may be positioned anywhere along the length of the base member to lift the bedding at any area or region relative to the user's body. For example, expansion members may be positioned at or near the user's feet, at or near the user's legs, at or near the user's torso, at or near the user's neck, at or near the user's head, or a combination thereof. In some examples, there may be more than one base member of the same or similar dimensions that can each be connected to the inflation system. For example, a first base member may be positioned at or near the user's feet and a second base member may be positioned at or near the user's neck; each of the base members may have one or more expandable chambers positioned thereon and each expandable chamber on each base member may be selectively inflatable. In some examples, one or more base members may be operable communication with a single inflation system. For example, a single inflation system may have one or more hoses, each configured to couple with a separate base member. An illustrative example of base member dimensions may be 1 or more wide and 1 or more long. For example, a base member may be 18 wide and 24 long. Another example may be a base member than is 18 wide and 30 long. In any example, the base member dimensions may be configured for the position and operation relative to the bed, user, or combination thereof.

[0047] FIGS. 5A to 5E show examples of expandable chambers that can be coupled to a base membrane. Each of the examples may have a corresponding attachment element configured to engage the base membrane. In any example, a lift system may comprise one or more expandable chambers and each expandable chamber may be used based on the needs or preference of the user. For example, the FIG. 5A shows a base member having sidewalls extending upward to a rounded or curved upper surface 200 configured to lift blankets to alleviate pressure from the blanket on the user. Any of the expandable chambers may have one or more surfaces configured to contact the user (e.g., the user's feet). For example, FIG. 5B illustrates an expandable member having a contacting surface 210 that may comprise a material most advantageous for user contact. Some examples of a contacting surface material may be a fabric or enclosed gel that can be configured to transfer heat from inside the expandable chamber to the user. In some examples, a contacting surface of an expandable member may comprise a separate chamber with less fill pressure to accommodate contact with the user. For example, a contacting surface may have an increased flexibility to allow the user to impress their feet or other body part into the expandable member. FIG. 5C illustrates a generally triangular expandable chamber that can provide lift to the bedding and may be configured to lift or elevate the user's feet when they are positioned on an inclined surface of the expandable member. FIGS. 5D and 5E illustrate examples of expandable members with a reduced footprint that can allow for precise elevation of the bedding. For example, the expandable member shown in FIG. 5E may be positionable on the base member and elevate bedding to a precise location relative to an area of the user's anatomy. In any example, expandable members may comprise any volume, dimension, geometry, etc.

[0048] In some examples, an expandable chamber may be comprised of light and durable material configured to accommodate the expansion, pressure, geometry, and transition capability from an expanded state to a collapsed state of each expandable chamber. For example, an expandable member can be configured to elevate bedsheets (e.g., tucked-in sheets or otherwise), blankets, etc. and may be configured to be sufficiently load-bearing. In some examples, expandable members may be comprised of a silicone coated nylon material similar to that material used in automotive airbags, while the expandable chambers used for therapeutic benefits (for the feet, neck and shoulders, etc.) may be comprised of nylon, mylar, fabric, or other materials. In some examples, the expandable chambers and/or base member may have a cover that can be removed and washed.

[0049] In use, the lift system can be positioned on a bed or other surface. Activating the lift system can raise a covering such as a blanket or other bedding off of the user to alleviate discomfort and allow for increased mobility under the bedding while still remaining covered. FIGS. 6 to 8B illustrate some examples of the lift system in position and use relative to a bed. Referring to FIG. 6, the base member 305 is in position near the foot of the bed 300. The foot of the bed may refer to an area of region of a bet generally where a user's feet would be. In FIG. 6, the foot of the bed is indicated at 301. The expandable chambers 310 and 315 are in an expanded or inflated configuration with a primary chamber (e.g., load bearing chamber 310 being taller or larger than expandable chamber 315. A blanket 304 is shown transparent to expose the lift system in use. It can be appreciated from this view, that the expanded configuration allows for a cavity where the blanket is lifted in front of expandable chamber 315, where the user's feet would be positioned. This added space can allow the user to lay on their back with their toes pointed up and unincumbered by the blanket because of the expandable chambers. In some examples, the primary or expandable chamber would be positioned in the back of the base member, so that when placed on the bed, this air chamber would be located closest to the foot of the bed 300. The primary expandable chamber 310 may comprise a heavier density than the more forward expandable chamber 315 to support increased load-bearing capacity. In some examples, the expandable chamber 315, closest to the user, can inflate up and toward the user's foot. This expandable chamber may have a contour configured to comfortably cushion the bottom of the user's feet. In some examples, the expandable chamber configured to contact the user's feet may be contoured in a U shape and can be a foot-stabilizing chamber configured to inflate and accommodate the user's feet in the trough of the U shape. For example, this Foot-Stabilizing type of embodiment can support the user's feet at normal angles or at a 90-degree angle with respect to the leg to substantially eliminate toe drop and nerve atrophy and its associated complications and other ailments.

[0050] In some examples, the dimensions of each expandable chamber may be configured based on the user's foot size. For example, a larger air chamber may be selected for a user with larger (e.g., longer feet that may require a taller expanded dimensions to properly support the lifting of the bedding and resulting cavity.

[0051] In some examples, both the primary expandable chamber and footrest or foot-stabilizing expandable chambers can fit inside an open end of the base membrane. The bottom of the air chambers can be wider than the width of the base member cutout and the protruding component of the air chamber can narrow down to just the width of base member cutout and reinforced at the seam between the protruding portion and base of such air chambers to ensure that none of the air chamber base can protrude beyond the bottom of the cutout surface.

[0052] FIG. 7A illustrates another example of placement of the lift system on a bed. Here, the base member 305 is positioned near the head of the bed 303 and the expandable members 310 and 315 are shown lifting the bedding 304 near where the user's upper body would be positioned. Although the expandable members 310 and 315 are shown from the side, one can appreciate that the position of the expandable members may be on either side of the user. In some examples, the base member may be positionable under the user's shoulders, neck and head whereby an expandable member may be selectively expanded (e.g., inflated) to provide support for the user's head and neck while sleeping. For example, the expandable member, in this example, may inflate to contact and provide appropriate anatomical support for the user's head and neck as a pillow or in support of a pillow. In such an example, when the expandable chamber is deflated, it can be configured to deflate around the pillow to collapse within the base member.

[0053] FIGS. 7B and 7C illustrate additional examples of placement of a base platform purposed to deploy a therapeutic expandable member for the head and neck area similar to FIG. 7A. Here, the Head & Neck base platform 305 is positioned to lay partially underneath the pillow and extending to approximately where a sleeping user's shoulders would lay. The therapeutic air chamber 315 is shown expanded (e.g., inflated) to provide therapeutic treatments to the user's (back-of-the) head and neck while sleeping. In some examples, this therapeutic air chamber may inflate to contact and provide appropriate anatomical support for the user's head and neck as a pillow or in support of a pillow. In both examples, when the therapeutic air chamber is deflated, it can be configured to deflate underneath the pillow to collapse fully within the head & neck base platform so as to not interfere with a sleeping user. Further, as illustrated in FIG. 7C. In the examples illustrated in FIGS. 7B and 7C, the expandable member 305 is configured to expand around the pillow to accommodate and support the user's neck by filling the void or space between the neck and the bed or pillow. In FIG. 7C, the expandable member is shown in a deflated configuration whereby the expandable member has deflated and retracted into the base platform. In this configuration, the expandable member may be configured to arrange the volume of air within the expandable member to allow for increased flexibility and compression at the point nearest the user's head. For example, the expandable member 315 may expand and the superior portion may be configured with increased flexibility, less air volume, or otherwise modify the air within the expandable chamber to promote comfort and support when inflated.

[0054] In some examples, a user may be tall and their body may extend the entire length or substantially the entire length of a mattress. Accordingly, positioning of the expandable members may be configured to facilitate the user's feet, ankles, and lower legs to extend between the expandable chambers. As illustrated in FIG. 8B, expandable chambers 320 and 325 are positioned on the base platform 330 in a flanked orientation allowing the user to extend their feet between the expandable members. In such an example, the void generated by lifting the blanket may be between each of the expandable members (similar to a position at or near the user's upper body). Similarly, FIG. 8C illustrates an example of a system described herein positioned on a bed and lifting the bedding off a person near their feet. In particular, FIG. 8C illustrates the base platform 305 as it may be configured for tall users who may require additional length on the surface of the bed. Accordingly, expandable members 320 and 325 are positioned flanking the user's feet allowing use of the full length of the bed when in use.

[0055] FIGS. 9A and 9B illustrate additional details of the lift system. FIG. 9A illustrates an example of two expandable chambers 405 and 410. Here, additional deflation valves 401 are positioned at the top of the expandable members. Inflation and deflation valves may be the same valve or different valves and may be at any position relative to the expandable chamber to facilitate the inflation and deflation. For example, inflation valves 403 and additional deflation valves 402 are shown at the bottom of the expandable chambers in FIG. 9A. From this profile view, examples of friction strips 420 are shown at the bottom of the base member configured to contact the bed surface and hold the base member in place. An example of height for elevation is provided in this view. However, the expandable chambers may be configured to expand upward to a height of 1 or more. For example, an expandable member can be configured to elevate bedding 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or more.

[0056] In FIG. 9B, an example of the cavity or space generated by the lift system is shown. For example, the expandable chamber 425 may be configured to contact the user's feet and support the space 431 to accommodate the user's feet. In this example, expandable chamber 430 is shown having a height of 432 and can be a load bearing or primary expandable chamber, configured to provide more support to the elevation of the bedding. Angle A is provided to show an example of a plane of the bed sheets and blankets or bedding as it transitions from contacting the upper surfaces of the expandable chambers down to contact the user (e.g., the user's legs). This angle may be adjustable by increasing or decreasing the height of the expandable members. In some examples, these dimensions of the expandable member height, angle of blanket path, cavity volume, etc. may be interpreted by a computer-based system to optimize and tailor the inflation of the expandable members.

[0057] As illustrated by FIG. 10, a lift system (e.g., bedding lift system) may be controlled by a remote device (e.g., an application on a mobile phone). The remote device may wireless communicate with the inflation system to control the expansion (e.g., inflation) of one or more of the expandable chambers. In some examples, the control of the inflation system may incorporate user attributes such as foot size, sleeping patterns, health characteristics, injuries, illness, etc. in the development of an inflation plan that can control the operation of the lift system. For example, a user may input their foot size and the lift system may activate the inflation system to expand one or more chamber according to the physical attributes of the user. In some examples, the lift system and further comprise one or more sensors such as a load sensor to determine the amount of pressure or load provided by the bedding on the expandable chambers to determine if sufficient expansion has been achieved. For example, a load sensor may indicate insufficient load on the expansion chamber and that may be interpreted as insufficient inflation causing the system to increase the inflation of the one or more of the expandable chambers. In FIG. 10, the remote operation of the lift system is illustrated where remote device 500 wireless communicates with the lift system 505 to expand or inflate the expandable chambers 510 and 515. Accordingly, the user may establish expansion pre-set values to allow for the rapid and tailored expansion of the expandable chambers to the most advantageous position relative to the user.

[0058] FIG. 11 illustrates an example of operating a lift system. In this example, the base member is positioned on the bed at step 600. Then, one or more expandable members are positioned on the base member at step 605. The inflation system is activated at step 610 to inflate or otherwise expand one or more of the expandable chambers. The user, or the system automatically, can then determine if a sufficient elevation of the bedding is achieved at step 615. Optionally, the therapeutic system may be activated at step 616. The therapeutic element may be initiated and heat, vibration, cooling, or other therapeutic stimulation may be supplied via the lift system (e.g., expandable chamber) at step 617. This can be continued as needed or according to preset time intervals, etc. via the remote or App. Finally, the lift system can remain in use until the user determines that the system can be deflated at step 620.

[0059] FIG. 12 illustrates some additional examples of the lift system in use. Here, expandable chambers 716 and 719 are positioned within the base 725 including openings 705 configured to allow the expandable members to expand and extend therethrough. In the retracted or compressed configuration at the top of FIG. 12, the expandable members 716 and 719 are deflated within the base 725. The openings 705 are arranged such that in use, at the bottom of FIG. 12, they are positioned proximal to the user's feet. When the expandable members are inflated they extend through the openings 705 to lift bedding and be positioned proximal to the user to lift the bedding and provide support. In some examples, deflation valves 716a/719a, as well as inflation valves 716b/719b can be configured to facilitate the transition from the compressed state to the expanded state. In some examples, the dimensions of the base may be any length or width. In the example illustrated in FIG. 12, the base may have a length or width in a range from less than 10 to greater than 30 or any length or width therebetween. For example, the base may be between 18 and 24. The height of the base in a retracted configuration with the expandable members therein may also be any height. For example, the height of the base in a retracted configuration may be 1, less than 1 or greater than 1. In some examples, the dimensions of the expandable members may be any dimensions. For example, the height of the expandable members may be less than 1 to greater than 10 or any height therebetween. In some examples, the base may and a height in a retracted configuration that is sufficiently low (e.g., flat) so as to render the base, including the retracted expandable members, undetectable under a blanket.

[0060] In some examples, as illustrated by FIGS. 13A and 13B, the base platform may comprise a first (e.g., bottom) side 715 and second (e.g., top) side 725. The first side 715 and second side 725 may be configured to fold over and engage one another. Referring to FIG. 13A, the base platform is shown in an open configuration exposing the interior of the base platform. A plurality of cutouts 705 are positioned around the surface of the top side 725. The cutouts 705 may be configured to engage expandable members as they transition between an inflated and deflated configuration. The second side 725 may be folded over and attached or otherwise engaged to the first side 715 via an attachment system such as a zipper, magnets, snap mechanisms, clips, hook and loop fasteners, etc. In the example illustrated by FIG. 13A, there are a plurality of expandable members (e.g., 716, 717, 718, 719, and 720). Each expandable chamber may be selectively activated (e.g., inflated) to an expanded state when the top side 725 is folded over the bottom side 715 and the expandable members may be inflated through the cutouts 705. An expansions system, control unit, and any other element may be operably coupled to one or more sides of the base platform. As illustrated in FIG. 13A, an example of an expansion system and control unit 721 are positioned on the first side 715 without a corresponding cutout as the control unit may be contained within the base platform when in use. In FIG. 13B, the base platform illustrated in 13A is shown in a folded configuration ready for use. The expandable members 716, 717, 718, 719, and 720 are expanded or ready to be expanded through the cutouts overlaying the expandable members.

[0061] Similar to the examples illustrated in FIGS. 13A and 13B, FIGS. 14A and 14B show an example of the base platform from a side elevation view with the expandable members 719 and 720 in a compressed state within the base platform in FIG. 14A. The cutouts 705 are provided on the top surface 725 with the expandable members being coupled to the bottom surface 715. As the expandable members are inflated through the cutouts, the base platform side elevation view is shown in the example of FIG. 14B with the expandable members 719 and 720 inflated through the cutouts 705 on the second side 725.

[0062] FIGS. 14A and 14B show examples of a base platform in a side elevation view. In these examples, the base platform may have a taper from one side to another. For example, in FIG. 14B, the side of the base platform adjacent to expandable member 720 may be thinner (e.g., 0.01 to 5) that the opposite side adjacent to expandable ember 719. This tapered configuration of the base platform can facilitate the accommodation of additional structures or elements (e.g., control unit, expansion system, etc.) without impacting the contact with a user. For example, the user may engage expandable member 720 with their feet whereby their heel can contact surface 725 without significant elevation of the foot from the bed surface. FIG. 14C illustrates another example or alternative of the base configurations illustrated in FIGS. 14A and 14B. Here, the top surface 125 still comprises a cutout 705 for the expandable member 719 to expand and extend therethrough. Here, a pouch 726 is now attached to the perimeter of cutout 705 with the expandable member 719. positioned therein. FIG. 14C shows the expandable member in a retracted position and the pouch 726 attached to the cutout perimeter 726a including attachment points (e.g., snap fit, friction fit, or other attachment means for the pouch 726 to be attached on one side to the cutout 705 and the bottom later of the base. The pouch 726 can be configured to direct a path of expansion for the expandable member to guide the expandable member to the cutout 705. In some examples, the pouch 726 may be tapered from the bottom of the base to the cutout perimeter 726a providing a tapered interior pouch geometry to guide the expandable member 719 to and through the opening 705. An additional example is illustrated in FIG. 14D. Similar to FIG. 14C, FIG. 14D shows an example of pouches 726 with the expandable members therein. In some examples, the expandable members 719 may be larger than the openings 705, as illustrated in the retracted or stowed configuration. The pouches 726 may provide additional support for directing the expansion of the larger expandable members 719 through the openings 705. Another illustrative example shown in FIG. 14D is a zipper 727 that may be configured to enclose the expandable members and the interior of the base 725. For example, when the zipper 727 is closed, the base may enclose the expandable members 719, pouches 726, such that the openings 705 are exposed to the interior of the enclosed base member 275 until they are expanded out from the openings. Yet another illustrative example shown in FIG. 14D are inflation valves 719a and deflation valves 719b in communication with the expandable members and configured to direct a flow or fluid (e.g., air) into and out of the expandable members causing them to transition between a retracted or compressed state to an expanded state.

[0063] In some examples, when the expandable members are in their compressed (deflated) and folded position they may be sandwiched within the base platform. The expandable member 720 may be an example of an expandable member configured to provide therapeutic elements to the feet. The expandable member 719 may be configured as an example of a load-bearing expandable member, which would be used to lift and hold bedsheets and blankets above a user's feet.

[0064] FIGS. 15A and 15B illustrate examples of expandable members as described herein. Referring to FIG. 15A, the expandable member 750 has an expansion chamber 755 as an enlarged or inflatable section superior to the expandable member base 760. The expandable member base can be configured to engage the base platform (e.g., on side 725) and the expansion chamber 755 may be configured to inflate or expand through a cutout (e.g., 705). In FIG. 15B, this example has an expandable member 770 with an expansion chamber 775 separated from the expandable member base 785 by an expandable member neck segment 790. The neck segment 790 can be configured to complement the geometry on the cutout (e.g., 705) without modification to the geometry of the expansion chamber. For example, the expandable member base 785 may be coupled to the base platform (e.g., 725) and, when expanded, the neck 790 and expansion chamber 775 can extend through the cutout while the neck 790 may be in contact with the cutout perimeter and the expansion chamber may be inflatable above a surface of the base platform (e.g., surface 725). In some examples, the expandable member base 785 may have an interior configured to receive the remaining segments of the expandable member when it is deflated. For example, the expandable member may be configured to deflate within itself and stowed inside of the expandable member base. In some examples, the expandable members may be configured to deflate and compress as illustrated in FIG. 14A.

[0065] FIGS. 16A and 16B illustrate another configuration of expandable members on a base platform. In FIG. 16A, expandable members 805 are positioned away from the center of the base platform 800 with an additional expandable chamber 810 that may optionally be positioned distal to the expandable members 805. In this configuration, a space between expandable members 805 may be configured to accommodate the feet of a user. For example, a user who is taller and generally requiring a full length of the bed may benefit from a configuration shown in FIG. 16A whereby their feet can extend along all or substantially all of the bed length while the expandable chambers elevate the bedding around their feet. FIG. 16B illustrates a top view of the configuration shown in FIG. 16A to highlight the space between expandable members 805 that can be configured to accommodate the user's feet.

[0066] In some examples, any of the lift systems described herein may have an additional attachment layer. For example, the base platform may have one or more layers (e.g., layers illustrated in FIGS. 4A to 4C) configured to operably couple with or engage an attachment layer to retain the base platform in a position on the bed. The attachment platform may be configured to be locatable under a fitted sheet of a bed. The attachment platform may have one or more magnets or similar elements configured to engage the base platform when it is positioned on top (e.g., externally) of the fitted sheet over, near, adjacent, etc. to the attachment form. In this example, the attachment platform may be positioned on the bed between the exterior of the bed and an interior surface of a fitted sheet. Then, the base platform can be positioned on or adjacent to the attachment platform and separated from the attachment platform by the fitted sheet material. The magnetic attachment of the attachment platform may engage corresponding magnets underneath the base platform and retain the base platform in position on the bed without the need for additional straps, coupling, etc.

[0067] In some examples, controlling the lift system can include the activation of the inflation system. This may include the activation or actuation of one or more valves. Accordingly, a battery pack may be provided with the inflation system to power the pump and valves during operation. As described herein, the expansion system (e.g., inflation system) may comprise one or more pumps configured to modify a volume of air, gas, fluid, etc. throughout each expandable chamber.

[0068] In some examples, the lift system can be configured to be scalable, portable enough to fit in a carry case, and modular with easy to replace or interchange components (e.g., base member, expandable chambers, inflation system, etc.). For example, the inflation system may comprise a sufficiently small air pump with enough power to inflate (e.g., expand) and deflate one or more expandable chambers. In some examples, position and placement of the air pump can be via fasteners underneath a bed or alongside the inside bedframe, where such a pump can have a cord (e.g., USB-C, etc.) that runs alongside the bedframe or underneath a bed and such cord can connect to an AC Power source at the head of a bed. In some examples, the pump or inflation system may be battery powered, in which case the pump/battery assembly would be rechargeable via an attachable cord. In some examples, deflation of the air chambers can be done via the same pump and also manually via a fail-safe manual deflation valve. In some examples, the pump may be a manual pump. In some examples, the pump may be a fluid pump and the expansion of one or more of the chambers may be facilitated by the flow of a fluid therein. For example, the inflation system may comprise a fluid reservoir configured to retain fluid for the expansion of the expandable chambers. In some examples, the lift system may also comprise a heating element or thermal adjustment mechanism configured to modulate the temperature of the interior of each expandable chamber. The thermal modulation element can provide or supply heat or cooling via an expandable chamber in contact with the user.

[0069] In some examples, air conduits or air tubes can be connected to various electronically controlled air valves within each chamber, with these air valves powered via small electric wires that are connected to a control unit. The control unit can be Bluetooth and/or Wi-Fi enabled which will allow the entire apparatus to be controlled via wireless remote control and smart phone Apps, have automatic software upgrades and other functionality. The control unit can be connected to the battery bank/air pump, which can power the entire apparatus for weeks without need for recharging. The control unit may be configured to control the inflation system and operation of the lift system.

[0070] In some examples, operating the lift system may comprise a two-person set up, the control unit will be capable of controlling more than one base member, each with their own air chambers with size specifications as described above, and each having separate air conduit and wires to interconnect with each other.

[0071] In some examples, the control units can be operated via a wireless (rechargeable) remote control and/or smartphone App. The remote control can have settings to inflate/deflate the blanket lift air chamber and footrest or foot-stabilizing air chamber on demand or according to clock settings such as for bedtime inflation and morning deflation.

[0072] In one more advanced embodiment for medical applications, the remote can have settings for cold or warm air deployment and to maintain, increase or decrease air temperature as well as a vibration feature option.

[0073] In all embodiments, the smart phone App (App) can provide the same functionality as the remote control, but it can feature smarter technology, such as connectivity to smart beds or smart watch apps like Garmin, Apple or Google that detect sleep, movement and when a person wakes up and gets out of bed. As such, the App can automatically inflate and deflate the air chambers or do things like remotely inflate the air chambers and bring air temperature of the footrest or foot-stabilizing air chamber to a desired setting. In some examples, a GPS locator can be incorporated into the lift system to prevent a user from losing the device. For example, a GPS-based chip and a counterpart chip placed in their luggage can provide an alert or series of alerts on their mobile phone if the device or system is lost.

[0074] The lift system described herein can be configured to provide therapeutic support and treatment of various diseases and conditions. The lift system (e.g., base member, expandable chambers, etc.) may comprise one or more therapeutic elements for the treatment and support of illness, injury, disease or conditions. Some examples of a therapeutic element may include the thermal transfer elements (e.g., gel covering, heating/cooling element, etc.) vibration elements, transcutaneous electrical nerve stimulation elements, massaging elements, etc. or a combination thereof. Any of the therapeutic elements may be used, included or employed individually or in combination with any or all other therapeutic elements.

[0075] In some examples, the lift system may comprise a heating or cooling element for thermal regulation. For example, one or more of the expandable chambers configured to contact a user may be configured to modify the temperature of the chamber and thereby the temperature of the contacting surface with the user.

[0076] In some examples, the lift system may comprise a vibration system configured to provide vibration to the user via a contacting surface of the expandable chamber with the vibration element. For example, vibrating motors may be insertable into such expandable (therapeutic) chambers designed to be in contact with the user (such as under the feet, neck, etc.) to provide vibration that may be adjustable to various intensities.

[0077] In some examples, the lift system may comprise a TENS element configured to supply electrical stimulation to the user based on a selected intensity.

[0078] In some examples, the lift system may automatically inflate, deflate, or change based on the medical condition and/or user response during sleep, as detected by the lift system.

[0079] Some examples of conditions, injuries, or illness the lift system may be configured to support and treat may be fibromyalgia, peripheral neuropathy, plantar fasciitis, diabetes pain, arthritis/osteoarthritis, shingles pain, foot ulcers, gout, restless leg syndrome, broken or sprained toe/foot/ankle, in-grown toenails, blisters

[0080] In another embodiment the plantar/footrest and foot-stabilizing air chambers can be modified to allow heated or cooled air and the air pump operation modified to interconnect with a heating and/or cooling element. Another embodiment of this forward air chamber can include a vibration element, that could be activated separately from or in combination with a cooling or heating element, and that such vibration feature could have various levels of intensity.

[0081] In some examples, the lift system may comprise an electronically-controlled device that provides relief to a person's toes and feet by lifting and retaining bedsheets, blankets and bedcovers above the toes, thus relieving the weight of such sheets pulling on the toes-particularly when sheets are tucked into the foot of a mattress; that such device also fully retract electronically to disappear under the sheets to restore a well-made bed and bedroom appearance and that operation of such device is done via remote control and/or smart phone app or manually as an alternative. In some examples, the lift system employs expandable chambers that inflate with sufficient force to lift and retain (tucked-in) bed sheets and/or blankets.

[0082] In some examples, operation of the lift system may be configured to be automatic. For example, the expandable chambers may be automatically deployed at bedtime and automatically deflated in the morning, thus being largely invisible under the bed cover and restoring a well-made bed and bedroom appearance and eliminating the need for manual set up or removal

[0083] In some examples, the lift system can be in communication with one or more remote devices and functional in combination with an application. For example, use and operation of the lift system may communicated with other remote systems and databases such as Garmin, Apple or Google that detect sleep, movement and when a person wakes up and gets out of bed. As such, the App can automatically inflate and deflate the air chambers or do things like remotely inflate the air chambers and bring air temperature of the footrest or foot-stabilizing air chamber to a desired setting.

[0084] In some examples, the expandable chambers can be configured to deploy through a flat, durable, reinforced nylon base membrane placed at the foot-end of a bed atop the bedsheet. Such base membrane dimensions can be sized approximately 18 to 24 (inches) deep and 24 to 30 wide, be sewn shut along three of the four edges, with one edge open to accommodate inserting the expandable chambers. That the top of such base membrane can comprise rearward and forward compartments through which the blanket-lifting and footrest or foot-stabilizing air ballasts or chambers can protrude, respectively, and that each compartment or cutout will have durable reinforced sewing along the edges so that the nylon fabric around these cutouts does not fray.

[0085] In some examples, the operation of the lift system may be based on a time period and can automatically inflate, deflate, etc. after a period of time. For example, the lift system may comprise expandable chambers set to deflate after a certain period of time such as 15 min, 30 min, 60 min, etc. and the air chambers can deflate and fold back into position underneath the pillow so as not to disrupt sleep, where the expandable chambers are positionable at or near the user's head and neck.

[0086] In some examples, the lift system can inflate and deflate sufficiently quietly to prevent disturbing the user during sleep. In some examples, the expandable chamber may be configured to provide lumbar or lower back support. For example, an expandable chamber may be positioned on a base member and configured to expand (e.g., inflate) to support the lower back of the user. For example, the base member may be used in a seated position, sleeping position, prone position, supine position, etc.

[0087] In some examples, the devices described herein can be configured for simple manufacture and design, affordability, reduce or eliminate daily user effort to setup or operate, and improve the aesthetic of the device when not in use. In some examples, the devices described herein can be configured to be used when traveling (e.g., easily portable).

[0088] Directional Deflation of Air Chambers. In some examples, the expandable chambers and/or base member may comprise one or more valves to facilitate deflation of the expandable chambers to ensure a low profile or flat configuration of the base member with the expandable chambers in a deflated configuration. For example, the inflation system may comprise a pump or other deflationary element configured to actively draw air out of the expandable chambers thereby ensuring the chambers are entirely deflated to the base member. For example, each expandable chamber may have a deflation valve in the side or back side of it to promote deflation. In any example, the lift system may be configured to be a portable system and can be configured for use during travel (e.g., in a vehicle or on an airplane).

[0089] In some examples, the base member may be thinner on one side or the other. For example, the membrane may be flat or nearly flat at the front (foot side) then taper in the rear. The tapered characteristic of the base member may support directional deflation of expandable members towards the foot of the bed, rather than deflating towards the front/feet. In some examples, the expandable members may be configured to deflate towards the side of the base member. In some examples, the position of deflation valves on the base member or expandable chambers may promote the directional deflation of the expandable chambers.

[0104] Terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. For example, as used herein, the singular forms a, an and the are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms comprises and/or comprising, when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. As used herein, the term and/or includes any and all combinations of one or more of the associated listed items and may be abbreviated as /.

[0105] Spatially relative terms, such as under, below, lower, over, upper and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms upwardly, downwardly, vertical, horizontal and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

[0106] Although the terms first and second may be used herein to describe various features/elements (including steps), these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed below could be termed a second feature/element, and similarly, a second feature/element discussed below could be termed a first feature/element without departing from the teachings of the present invention.

[0107] Throughout this specification and the claims which follow, unless the context requires otherwise, the word comprise, and variations such as comprises and comprising means various components can be co-jointly employed in the methods and articles (e.g., compositions and apparatuses including device and methods). For example, the term comprising will be understood to imply the inclusion of any stated elements or steps but not the exclusion of any other elements or steps.

[0108] In general, any of the apparatuses and methods described herein should be understood to be inclusive, but all or a sub-set of the components and/or steps may alternatively be exclusive, and may be expressed as consisting of or alternatively consisting essentially of the various components, steps, sub-components or sub-steps.

[0109] As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word about or approximately, even if the term does not expressly appear. The phrase about or approximately may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/0.1% of the stated value (or range of values), +/1% of the stated value (or range of values), +/2% of the stated value (or range of values), +/5% of the stated value (or range of values), +/10% of the stated value (or range of values), etc. Any numerical values given herein should also be understood to include about or approximately that value unless the context indicates otherwise. For example, if the value 10 is disclosed, then about 10 is also disclosed. Any numerical range recited herein is intended to include all sub-ranges subsumed therein. It is also understood that when a value is disclosed that less than or equal to the value, greater than or equal to the value and possible ranges between values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value X is disclosed the less than or equal to X as well as greater than or equal to X (e.g., where X is a numerical value) is also disclosed. It is also understood that the throughout the application, data is provided in a number of different formats, and that this data represents endpoints and starting points, and ranges for any combination of the data points. For example, if a particular data point 10 and a particular data point 15 are disclosed, it is understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed as well as between 10 and 15. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.

[0110] Although various illustrative embodiments are described above, any of a number of changes may be made to various embodiments without departing from the scope of the invention as described by the claims. For example, the order in which various described method steps are performed may often be changed in alternative embodiments, and in other alternative embodiments one or more method steps may be skipped altogether. Optional features of various device and system embodiments may be included in some embodiments and not in others. Therefore, the foregoing description is provided primarily for exemplary purposes and should not be interpreted to limit the scope of the invention as it is set forth in the claims.

[0111] The examples and illustrations included herein show, by way of illustration and not of limitation, specific embodiments in which the subject matter may be practiced. As mentioned, other embodiments may be utilized and derived there from, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. Such embodiments of the inventive subject matter may be referred to herein individually or collectively by the term invention merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept, if more than one is, in fact, disclosed. Thus, although specific embodiments have been illustrated and described herein, any arrangement calculated to achieve the same purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description.
