Any and all patents and other publications identified in this specification are incorporated by reference as though fully set forth herein.

(27) Also, as used in the specification including the appended claims, the singular forms a, an, and the include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from about or approximately one particular value and/or to about or approximately another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent about, it will be understood that the particular value forms another embodiment.

(28) With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1-3 show a mobile device 10 for supporting and moving an infant or child, according to an example embodiment of the invention. The device 10 generally comprises a support frame 20 and a seat or resting portion 40 supported on the support frame. The seat or resting portion 40 can be coupled directly to the support frame 20, or can be indirectly coupled to the frame by one or more intermediate couplings, linkages or connection members. Optionally, at least some degree of freedom of movement is provided between the seat or resting portion 40 and the support frame 20, for example allowing a rocking, jiggle, bounce, swing or other range of motion of the seat or resting portion relative to the support frame and underlying support surface. In example forms, the mobile support device is configured for use with zero to six month old infants, where access by, proximity to and interaction with a parent or other adult caregiver is most frequently needed, but in alternate forms may be adapted to other uses.

(29) The support frame 20 preferably comprises one or more (four in the depicted embodiment) support legs or columns 22 for providing structural support to hold the seat or resting portion 40 at an elevation above the floor or other support surface. One or more cross-members or braces 24 extend between the legs 22 and/or between other braces. Wheels or rollers 26 mounted to distal or lower ends of the legs 22 allow for ease of mobility of the mobile support device 10 along the floor or other support surface. Optionally the wheels 26 comprise caster wheels or otherwise pivot or turn to provide ease of maneuverability. In example forms, the diameter of the wheels 26 is between about 2.5-5, more preferably between about 3-4, for example about 3.5. The frame 20 is optionally foldable or collapsible for compact storage and transport, for example by means of one or more hinged connections, pins, snap buttons, or other connection or coupling means. A storage tray 28 or other container or compartment for holding toys or other items is optionally mounted to a cross-member 24 or otherwise attached to the frame 20.

(30) In example embodiments, the distal or lower ends of the legs 22 of the support frame 20 define an outline or periphery P along the floor or other support surface, as shown in broken lines in FIG. 2, within the upward projection of which the mobile support device 10 is substantially or entirely contained. In the depicted embodiment, the periphery P is generally rectangular or square in profile, being defined about four legs 22, but in alternate embodiments may be for example triangular, polygonal or circular in profile depending on the number and configuration of the legs of the support frame. In example embodiments, the periphery P is between about 14-23 wide, preferably between about 16-20 wide, and for example about 18 wide in width (W), by between about 19-31, preferably between about 22-28, and for example about 25 long in length (L), for example about 1825, defining a length-to-width aspect ratio (L/W) of between about 0.8-2.2, preferably between about 1.1-1.8, and for example about 1.4. Optionally, the legs 22 are generally arcuate, such that their lower or distal portions are more vertically oriented and their upper or proximal portions curve to a more horizontal or oblique angle, with the curvature being convex or outwardly directed. The cross-braces 24 are optionally inset from an upward projection of the periphery P, for example by providing them with an inward or concave curvature and/or by attachment inwardly of the support legs 22, as seen best with reference to FIG. 3. In this manner, the mobile support device 10 can be positioned in close proximity to a caregiver seated on furniture, without the support frame 20 interfering with movement and positioning of the device.

(31) In example embodiments, the seat or resting portion 40 comprises a fabric or soft-goods sling 42, forming a reclined seat or bassinet for comfortably receiving an infant or child, mounted to a seat frame 44. The sling 42 optionally comprises structural bracing and/or padding for improved comfort and positioning. One or more straps or harness connections are optionally provided to secure the child in the sling 42. The sling 42 and/or the seat frame 44 are optionally repositionable to allow adjustment of the inclination, elevation or other positioning of the seat or resting portion 40, for example by means of a cinch cord or strap, snap couplings, pivotal connection, or other positional adjustment means. In example embodiments, the seat or resting portion 40 is positioned or positionable at an angle of inclination of between about 15-40 from horizontal, for example about 27.5 relative to the horizontal.

(32) The mobile support device 10 preferably further comprises a multi-point accessible handle 60 having a plurality of gripping or contact surfaces positioned at different points about the seat or resting portion 40. In example embodiments, the handle 60 provides access for gripping adjacent at least two of the head end, foot end, left side and/or right side of the seat or resting portion 40, and more preferably from three or all four sides thereof. In the depicted embodiment, the handle 60 comprises oval or elliptically shaped wrap-around or perimeter handle or gripping halo extending about all or a substantial portion of the seat or resting portion 40. In this manner, the handle can be gripped to push or pull the device 10 from any position for improved mobility and maneuverability. Provision of a wrap-around handle or halo as in the depicted embodiment allows the handle to serve the additional function of a protective bumper about the seat or resting portion 40 of the mobile support device 10. The handle 60 is preferably positioned adjacent or in close proximity below the upper rim of the seat or resting portion 40 formed by the seat frame 44, and closely or generally conforms to the peripheral profile of the seat frame. In example embodiments, the wrap-around handle 60 defines an upper support frame portion that generally aligns with the upward projection of the periphery P of the lower support frame 20. In alternate embodiments, the wrap-around handle 60 may be offset from the projection of periphery P of the lower support frame 20; either inwardly offset relative to the lower support frame for improved stability, or outwardly offset for improved access and proximity to the infant by an adult caregiver when the lower support frame is positioned against a sofa or other furniture.

(33) In example embodiments, the handle 60 is coupled to the support frame 20, and the seat frame 44 is suspended from or otherwise coupled to the handle. A hinge connection, one or more springs, or other articulation means operably connected between the seat frame 44 and the handle 60 or the support frame 20 optionally allows movement of the seat or resting portion 40 relative to the support frame, for soothing or engaging an infant or child positioned in the mobile support device 10. In example embodiments, the seat 40 may jiggle, rock, swing, bounce or otherwise move. A motorized or manually energized movement mechanism is optionally provided. A pivotal coupling is optionally provided between the support frame 20 and the handle 60 to allow adjustment of the inclination of the seat 40. An upper member 80, such as a canopy, toy bar or handle is optionally attached over the seat 40, for example by pivotal or fixed attachment to a multi-connection hub or mounting member 82 coupling with the support frame 20 and/or the handle 60. Optionally, a vibration unit can be coupled to the support frame 20 or seat frame 44 for soothing the infant or child positioned in the mobile support device 10.

(34) In example embodiments, the mobile support device is configured to position the infant or child at an elevation or height and/or at an orientation that is optimized for access, proximity and interaction with an adult caregiver in various situations, for example while the caregiver is standing, walking, seated at a table for dining, or seated in a sofa, easy chair or other adult furniture. For example, the nominal or median height (H) of the seat or resting portion 40 may be positioned at about 21-36 above the floor, and more preferably at a height of about 26-32, for example about 29 high; thereby, for example, defining a height-to-width (H/W) aspect ratio of between about 0.9-2.6, preferably between about 1.3-2.0, and for example about 1.6; and a length-to-width (L/W) aspect ratio of between about 0.8-2.2, preferably between about 1.1-1.8, and for example about 1.4. Optionally, the height of the seat or resting portion 40 may be adjustable. In example embodiments, the wrap-around handle 60 may be inclined at an oblique angle of for example about 15-40, for example about 27.5 relative to the horizontal or have a staggered profile along its length, whereby a lower portion at the foot end of the seat 40 is positioned lower than the nominal or median height (H) of the seat, thus providing a convenient gripping position for the caregiver when seated; and an upper portion at the head end of the seat is positioned higher than the nominal or median height, thus providing a convenient gripping position for the caregiver when standing or walking. In example embodiments, the elevation of the handle at the foot end is between about 13-22 high, preferably between about 16-19 in height, and for example about 17.5 above the floor; and the elevation of the handle at the head end is between about 22-38 high, preferably between about 27-33 in height, and for example about 30 above the floor. In this manner the height of the seat or resting portion allows a line-of-sight eye-contact interaction between an infant on the seat or resting portion and an adult seated at a standard dining table, and also allows close proximity between the infant on the seat or resting portion and an adult seated on a standard sofa. For example, the mobile support device may be positioned adjacent a standard sofa with the infant being within 12-36, and preferably within 24 or less, from the adult; and/or the line of sight between the infant's eye-level and the adult's eye level is between about 0-30, preferably 15 or less, relative to horizontal, when the infant is positioned about 48-60 from the adult at a dining table.

(35) FIGS. 4A-4C show one alternate embodiment of a mobile support device 110, FIG. 4D shows another alternate embodiment of a mobile support device 210, and FIGS. 4E and 4F show still another alternate embodiment of a mobile support device 310, according to various forms of the invention. In its various forms, the child support device comprises a frame configured to rest on a support surface and a seat coupled to the frame and adapted for receiving an infant. Preferably, the support device includes one or more wheel assemblies, or other rolling/sliding means, which allow the support device to be rolled across the support surface. Example embodiments of the wheel assemblies can include a locking mechanism to selectively prohibit rolling of the child support device. The wheel assemblies can also or alternatively include a braking mechanism that engages in the event of accidental rolling. For example, one or more of the wheel assemblies 126 of the movable support device 110 can comprise a brake 127 for selectively engaging to prevent rotation of the wheel to resist movement of the device, or disengaging to release the wheel and allow movement of the device. A handle can also be included to facilitate a caregiver pushing or pulling the support device from room to room. Example embodiments of the handle are movable between various positions, such as above, behind, or in front of the seat. The seat can be coupled to the frame by way of one or more resilient members, such as springs or compliant wires that allow the seat to bounce or jiggle with respect to the frame. This bouncing motion can be soothing to children, and the resilient suspension can soften the jarring effect of any bumps as the support device is wheeled from place to place. Example embodiments of the seat can also be selectively reclined with respect to the support surface, either via adjustable soft-goods or by a mechanical recline adjustment mechanism. Moreover, various accessories can be attached to the child support device, such as a vibration unit, a tray, and/or a storage bin. The support device can further be configured to collapse for easy storage and transport.

(36) In further alternate embodiments, the seat or resting portion is optionally detachable and removable from a coupling or receiver of the lower support frame. In this manner, the lower support frame can provide a docking station for one or more interchangeable seat, carrier, support, changing table or other accessories that can be selectively attached to and removed from the coupling of the lower support frame.

(37) For improved mobility of the device and accessibility to the infant or child, example embodiments of the mobile support device according to the present invention do not include any feeding tray, push-handle or other components as are commonly included on high-chairs or strollers, or at least do not include such components in a position or configuration extending substantially beyond the upward projection of the periphery of the device's support frame where they could interfere with mobility, maneuverability, access, proximity or interaction with the infant. Optionally, as depicted in FIG. 4D, a tray 230 may project outwardly from the upper portion of the support frame 220 at least partially beyond the upward projection of the periphery of the support frame, but is preferably positioned so as not to interfere with mobility, maneuverability, access, proximity or interaction with the infant.

(38) FIGS. 5-10 show a support device 410 according to another example embodiment of the invention. The support device 410 includes a support component such as a seat 420 removably mounted to a support base frame 450. The seat portion 420 optionally comprises an internal support structure and fabric or other exterior soft goods forming a receiving area for positioning an infant or child. The seat 420 includes a handle 422 or gripping portion extending around all or a substantial portion of the periphery of the seat. In alternate embodiments, the handle extends in different positions from the front, rear, sides, and/or other parts of the seat 420, to facilitate a caregiver pushing, pulling, carrying, or otherwise moving the device 410 from room to room. The handle can also be used to aid a caregiver in adjusting the orientation of the seat or for manually imparting a bouncing or jiggling motion to the seat. The handle 422 is optionally repositionable to raise or lower its height. The seat 420 optionally includes a canopy or toy bar 424 extending over the receiving area of the seat, a feeding tray, a storage compartment, one or more seat belts or harnesses, and/or other accessories. An incline-recline positional adjustment mechanism 426 is optionally provided on the back section of the seat 420, as shown in FIG. 6, for example in the form of an adjustable positioning strap, one or more zippers, buckles, or other fasteners. Alternatively, the seat 420 is mounted to the frame 450 with an adjustable coupling allowing selective adjustment of the incline or recline of the seat.

(39) FIGS. 7A and 7B show the support frame portion 450 in greater detail, with the seat portion 420 detached therefrom. The frame 450 is adapted to rest on a support surface such as a floor and support the seat 420, and optionally provide mobility for the support device. The frame 450 comprises a pair of front legs 452 and a pair of rear legs 454 pivotally connected to one another at upper ends thereof by a hinged hub 456. The front and rear legs 452, 454 optionally include roller wheels or casters 458 at lower ends thereof, to allow rolling mobility of the support device 410. One or more of the wheels 458 optionally include a locking mechanism to selectively allow or prevent rolling of the device 410, and/or a braking mechanism that engages in the event of accidental rolling. Optionally, a single-action braking mechanism allows locking or braking on all or a plurality of the wheels 458 upon operation of a single actuator. Hinged cross-braces comprising first and second segments 460, 462 interconnect between the front legs 452 and rear legs 454, with a hinged joint 464 allowing folding of the frame 450 between an open (FIG. 7A) position for use and a folded (FIG. 7B) position for storage or transport. Front and rear transverse cross-members 470, 472 extend between the front legs 452 and rear legs 454, respectively. An accessory storage platform 476, for example including one or more storage compartments, cup-holders and/or other accessories is optionally provided, for example pivotally connected to the front legs 452 and attached to the first segments 460 of the hinged cross-braces on each side of the frame 450. The hubs 456 optionally include receivers 480, latches or other connectors for releasable and detachable coupling of the seat 420 to the frame 450. The frame 450 is optionally configured for use independently of the seat 420, for example with one or more different infant or child support components or resting portions, such as seats, bassinets, sleepers, rockers, etc., that can be interchangeably mounted to the frame, and/or having seating or support portions built into the frame itself. The receivers 480 are optionally of a universal configuration, compatible with corresponding mounting members of multiple different types of seats or other support components or resting portions for child support devices. FIGS. 8 and 9 show an alternate embodiment of the support device 410, with a frame 450 that is foldable between an expanded configuration (FIG. 8) and a folded configuration (FIG. 9), and without a storage platform or lower cross-braces bridging between the front and rear legs 452, 454.

(40) The support component or seat 420 can be coupled directly to the support frame 450 or can be indirectly coupled to the frame by one or more intermediate couplings, linkages or connection components. Further, the seat 420 can be coupled to the support frame 450 by way of one or more resilient members, such as springs or flexible or compliant wires that allow the seat to bounce or jiggle with respect to the frame. This bouncing motion can be soothing to children resting in the seat 420, and the resilient suspension can soften the jarring effect of any bumps as the support device 410 is wheeled from place to place. In alternate embodiments, the movement of the seat 420 relative to the frame 450 can be in the form of bouncing, rocking, swinging, swaying, jiggling, vibration, or other form of motion, and may include a lock/release mechanism to allow the user to selectively permit motion or fix the seat in position relative to the frame. The movement of the seat 420 can be manually provided by an adult caregiver, or can be automatically generated, as by an electric motor or magnetic drive. Optionally, a locking mechanism can be provided for selectively allowing or prohibiting bouncing or other motion of the seat relative to the frame. The locking mechanism can be configured to automatically engage when the seat is oriented in an inclined orientation. Alternatively, the locking mechanism can be configured to automatically engage when the seat is oriented in a reclined orientation, or the locking mechanism can be selectively engageable by a caregiver. In example embodiments, the seat 420 is optionally removable from the frame 450 and usable independently of the frame. In alternate embodiments, the seat 420 is permanently or semi-permanently attached to the frame 450.

(41) The support component or seat 420 can comprise a dual-mode child-containment device, detachably mounted to the frame 450, and selectively reconfigurable by the user between a first mode of use mounted to the frame (FIG. 5) and a second mode of use independent of the frame (FIG. 10). For example, in the depicted embodiment, the seat 420 comprises mounting flanges 430 on each side for releasable attachment in the receivers 480 of the frame, to mount the seat to the frame in the first mode of use. The seat 420 also includes a support base 440 for supporting the seat on a floor or other support surface independent of the frame 450. The seat support base 440 optionally allows a user to impart motion to the seat 420 in its independent mode of use. For example, the seat support base 440 can include resilient members such as flexible spring arms, curved rockers, a resilient bouncer mechanism, and/or an electrical vibration unit. In this manner, the seat 420 can function independently of the frame as a bouncer, a rocker, an infant support seat, or other infant or child support device. FIG. 11 shows an alternate embodiment of a seat 420 having a pivotally mounted or resilient support base 440, for example providing for spring-like bouncing movement of the seat when positioned upon a floor or other support surface.

(42) In example embodiments, the seat 420 and frame 450 are configured to provide the support device 410 with height, width, length, seating angle and other geometric size, dimensional ratios, and/or shape characteristics as described above. In alternate embodiments, the frame comprises height-adjustment features, for example telescoping legs and/or a repositionable coupling between the frame and the seat, to accommodate the support device 410 to a variety of applications, such as for example, to generally match sofa-height, table height, counter-height, bed-height, or other positions of an adult caregiver, to position a child at approximately corresponding eye level with the caregiver. The size and geometrical configuration of the support device 410 preferably provides a high degree of stability in forward, rearward and sideward directions, while also maintaining ease of mobility and interactivity between a child in the support device and an adult caregiver. In example embodiments, the support device 410 resists tipping over with: a child or simulated child load weight of about 7.5 pounds (3.4 kg)-17.5 pounds (8.0 kg) in the seating area, upon application of a static downward vertical force of about 21 Ibf (93 N) within about 5 seconds, and maintained for another about 60 seconds, when positioned on a surface inclined at about 20 in the most unfavorable sideward or rearward position, and maintained for about 1 minute; and/or with a 23 lbf (10.35 kg) static vertical load on the handle, and a horizontal force of about 5 lb. (22 N) applied at the same point on the handle, and the vertical and horizontal forces maintained for about 10 seconds; and/or positioned on a surface inclined at about 20 from horizontal, applying a 23 lb. (10.4 kg) static vertical load along an upper side surface, and applying a horizontal force of about 5 lbf (22 N) within 5 seconds at the same location as the vertical load, and maintaining the vertical and horizontal loads for about 10 seconds.

(47) FIGS. 17, 18 and 19 show additional embodiments of child support devices 810, 910 and 1010, respectively, having several different forms of feeding trays according to example forms of the present invention. In the embodiment of FIG. 17, the support device 810 comprises a seat 820 mounted to a frame 850, and a feeding tray 831 detachably coupled to the seat. In example embodiments the seat 820 is movably coupled to the frame 850, for example by a pivotal coupling or rocking hub, to allow for reciprocating motion with respect to the frame, for example providing a rocking, swinging, swaying, gliding or other range of motion. The seat is optionally detachable from the frame, and the frame is optionally foldable, for example having substantially similar seat and/or frame configurations as described in greater detail above. In the embodiment of FIG. 18, the support device 910 comprises a seat 920 mounted to a frame 950, and a feeding tray 931 mounted to the seat or frame in a horizontally pivotal configuration, allowing the tray to pivot between a first configuration in front of the seat for feeding and a second configuration to the side of the seat for access in placing and removing the child to and from the seat. The tray 931 can include one or more surface compartments, which are optionally removable or which receive removable dishwasher-safe liners for ease of cleaning. In the embodiment of FIG. 19, the support device 1010 comprises a seat 1020 mounted to a frame 1050, and a feeding tray 1031 mounted to the seat or frame in a vertically pivotal configuration, allowing the tray to pivot between a first configuration in front of the seat for feeding and a second configuration away from the seat for access in placing and removing the child to and from the seat.

(48) FIG. 20 shows another example embodiment of a child support device 1110, having a seat portion 1120 removably mounted on a frame portion 1150. The frame optionally allows adjustment of the seating height, and the seat is optionally movable relative to the frame, for example to allow for adjustment of the incline-recline position of the seat, and/or to impart a rocking, swinging, swaying, bouncing, jiggling, vibrational or other movement.

(49) FIGS. 21A and 21B show a reconfigurable seat 1220, according to another example embodiment of the invention. The seat 1220 can be configured for mounting to a support frame in similar fashion as described above in a first mode of operation, and for use in one or more additional modes of operation independent of the frame. For example, FIG. 21A shows the seat 1220 in a fixed position mode of operation independent of the frame, and FIG. 21B shows the seat 1220 in a rocking mode of operation independent of the frame. The seat 1220 includes a base 1243 having receivers for engaging a pair of repositionable arcuate support members 1245. In the fixed position mode (FIG. 21A) the arcuate support members 1245 are engaged in the receivers of the base 1243 with their concave sides oriented downwardly, so that ends of the arcuate support members rest on the floor or other support surface and retain the seat 1220 in a stable, fixed position. In the rocking mode (FIG. 21B) the arcuate support members 1245 are engaged in the receivers of the base 1243 with their convex sides oriented downwardly, so arcuate support members can rock on the floor or other support surface.

(50) FIGS. 22, 23A and 23B show another example embodiment of a child support device 1310, having a seat 1320 mounted to a frame 1350. A cross member base or trolley 1375 extends between the lower ends of the rear legs and aids in preventing the support device from tipping over when it is tilted onto its rear legs for rolling movement. The cross member or trolley 1375 can also include one or more wheels, for providing mobility to the support device 1310. For example, in the depicted embodiment, the cross member or trolley 1375 comprises an arcuate member having a first pair of larger wheels 1377 at its forward distal ends, and a second pair of smaller wheels 1379 on the lower surface of its medial portion. The medial portion of the cross member or trolley 1375 is angularly offset, such that the smaller wheels 1379 are raised off of the ground when the support device 1310 is positioned for use with its front legs on the ground (FIG. 23A), and contact of the front legs on the ground prevents rolling movement of the support device. When the support device 1310 is tipped rearwardly with its front legs raised off the ground (FIG. 23B), the smaller wheels 1379 and the larger wheels 1377 provide a stable rolling platform for moving the support device. The horizontal offset between the smaller wheels 1379 and the larger wheels 1377 resists tipping of the support device during rolling movement.

(51) In an example manner of use, as shown in FIG. 24, an adult caregiver A can easily move a support device D according to any of the embodiments described herein, with a child or infant I resting in the support device. The support device D is particularly configured for ease of mobility, stability, and accessibility. For example, the support device D can be rolled from room to room within various living quarters through standard doorways.
