[0019] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0020] As noted above, there is a long-felt need in the art for a device that allows a single user to aid a fallen individual. There also exists a long-felt need in the art for an inflatable chair lifting device, that does not require a single user to be physically capable of lifting a fallen individual to aid the fallen individual in standing. In addition, there exists a long-felt need in the art for an inflatable chair lifting device that prevents a user from becoming injured by attempting to lift a fallen individual.

[0021] The present invention, in one exemplary embodiment, is comprised of an inflatable chair lifting device primarily comprised of an inflatable body further comprised of a pair of side members, a backrest member, a front member, a seat member, an electric pump and a foot pump. The body is preferably hollow and inflatable, and may be generally configured as a chair, a stool, a bed, etc., or any other suitable three-dimensional shape as is known in the art. The body is also preferably manufactured from any suitable material as is known in the art, but is preferably made of a plastic that can be inflated. In the preferred embodiment, the body is configured in the general shape of a chair and has a pair of side members that act as armrests, a backrest member that supports the back of a user, a seat member that allows a user to sit on the body and a front member that a user can rest his or her legs against. Further, the device may have a one-piece hollow body or a body that has internal sections.

[0022] The body may also be comprised of an inflation valve that allows a user to manually inflate the body by blowing air into the body from the lungs. Additionally or alternatively, the body may be comprised of an integrated electric pump, that is integrally formed to the body, such that a user can easily inflate and deflate the body by pressing at least one button located on the pump. The pump is further powered by a battery. In addition, the device may also be comprised of a foot pump, that provides another means for a user to manually inflate the body. The pump is further comprised of a hollow, collapsible, accordion-like body that is fixedly or removably-connected to a hollow tubing, wherein the end of the tubing is further comprised of a hollow protrusion. The protrusion can be inserted into the inflation valve, to allow a user to inflate the body of the device via repeatedly pressing down on the foot pump body. Further, the body may be comprised of a deflation valve, to allow a user to deflate the body.

[0023] The device can further be used in a method to aid a user who has fallen and cannot get up unassisted or cannot be easily lifted by other nearby individuals. To aid a fallen user in getting up, a second user first places the device, while in an uninflated state, underneath the body of the first user who has fallen and is lying on the ground. Then, a second user inflates the body manually by using the inflation valve and blowing air into the body, inflating the body via the electric pump and/or inflating the body via the foot pump. As the body begins to inflate, the body will begin to form a generally chair-like shape and the first user will be lifted upwards into a sitting position. Once the body has been fully inflated, the first user will be in a sitting position and can then get up from the body, unassisted or with the assistance of the second user.

[0024] Accordingly, the inflatable chair lifting device of the present invention is particularly advantageous as it allows a single user to aid an individual who has fallen. The device further does not require a single user to be physically capable of lifting a fallen individual, to aid the fallen individual in standing. In addition, the device prevents a user from becoming injured by attempting to lift a fallen user. In this manner, the inflatable chair lifting device overcomes the limitations of existing methods of lifting a fallen individual known in the art.

[0025] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one embodiment of the inflatable chair lifting device 100 of the present invention in an uninflated state. The device 100 is primarily comprised of an inflatable body 110, further comprised of a pair of side members 112, a backrest member 114, a front member 116, a seat member 118, an electric pump 140 and a foot pump 150. The body 110 is preferably hollow and inflatable. In differing embodiments, the body 110 may be generally configured as a chair, a stool, a bed, etc., or any other suitable three-dimensional shape as is known in the art, such as but not limited to, a circular, an oval, a square, a rectangle, a triangle, a trapezoid, an octagon, a hexagon, etc. The body 110 is preferably manufactured from any suitable material as is known in the art, but is preferably made of a plastic that can be inflated, such as but not limited to: acrylic, polycarbonate, polyethylene, thermoplastic, acrylonitrile butadiene styrene, low density polyethylene, medium density polyethylene, high density polyethylene, polyethylene terephthalate, polyvinyl chloride, polystyrene, polylactic acid, acetal, nylon, etc.

[0026] In the preferred embodiment, the body 110 is configured in the general shape of a chair. Specifically, the body 110 has a pair of side members 112 that act as armrests, a backrest member 114 that supports the back of a user 10, a seat member 118 that allows a user to sit on the body 110 and a front member 116 that a user 10 can rest his or her legs against. It is further contemplated that any embodiment of the device 100 may have a one-piece hollow body or a body 110 that has internal sections (i.e. compartments) for each member 112, 114, 116, 118 of the body 110. In an embodiment with internal sections, each member 112, 114, 116, 118 of the body 110 is sealed from one another, such that each member 112, 114, 116, 118 can be inflated individually. In this manner, if one member 112, 114, 116, 118 becomes punctured or deflates, the rest of the members 112, 114, 116, 118 will not deflate. To allow for easy manual deflation of the device 100, the body 110 may also be comprised of a release valve 130, that can be opened to allow air to exit the body 110.

[0027] FIGS. 2-3 illustrate a perspective view of one embodiment of the inflatable chair lifting device 100 of the present invention in an inflated state. To fully inflate the body 110 (as seen in FIG. 3), the body 110 is comprised of an inflation valve 120. The inflation valve 120 allows a user 10 to manually inflate the body 110 by blowing air into the body 110 from the lungs. Additionally or alternatively, the body 110 may be comprised of an integrated electric pump 140. The electric pump 140 is integrally formed to the body 110, such that a user can easily inflate and deflate the body 110 by a pressing at least one button 146 located on the pump 140.

[0028] The pump 140 is further powered by a battery 142. The battery 142 may be a disposable battery or a rechargeable battery in the form of an alkaline, nickel-cadmium, nickel-metal hydride battery, etc., such as any 3V-12 volts DC battery or other suitable conventional battery as is known in the art, such as A, AA, AAA, etc., that supply power to the device 100. Throughout this specification the term “battery” may be used interchangeably to refer to one or more wet or dry cells or batteries of cells in which chemical energy is converted into electricity and used as a source of DC power. References to recharging or replacing the battery 142 may refer to recharging or replacing individual cells, individual batteries of cells, or a package of multiple battery cells as is appropriate for any given battery technology that may be used. In addition, a rechargeable embodiment of the battery 142 may be recharged using a USB port 144, wherein the USB port 144 is a USB-A, USB-B, Micro-B, Micro-USB, Mini-USB or USB-C port. The battery 142 may also be powered and/or recharged via a power cord 148 that can be plugged into a 120V/240V outlet.

[0029] FIG. 4 illustrates a perspective view of one embodiment of a foot pump 150 for the inflatable chair lifting device 100 of the present invention. The device 100 may also be comprised of a foot pump 150 that provides another means for a user to manually inflate the body 110. The pump 150 is further comprised of a hollow, collapsible, accordion-like body 152 that is fixedly or removably-connected to a hollow tubing 154. The end of the tubing 154 is further comprised of a hollow protrusion 156, that can be inserted into the inflation valve 120. As a result, after inserting the protrusion 156 into the valve 120, a user can repeatedly press down on the body 152 by stepping on the body 152 or repeatedly pressing on the body 152 with their hands to inflate the body 110.

[0030] FIG. 5 illustrates a flow chart of one potential method 200 of using the inflatable chair lifting device 100 of the present invention. The device 100 can further be used to aid a user 10 who has fallen and cannot get up unassisted or cannot be easily lifted by other nearby users. To aid a fallen user 10 in getting up, at 202 a second user first places the device 100, while in an uninflated state (as seen in FIG. 1), underneath the body 110 of the first user 10 who has fallen and is lying on the ground. Then at 204, a second user inflates the body 110 manually by using the inflation valve 120 and blowing air into the body 110 or inflating the body 110 via the electric pump 140 and/or inflating the body 110 via the foot pump 150. As the body 110 begins to inflate, at 206 the body 110 will begin to form a generally chair-like shape. As this occurs, at 208 the first user 10 will be lifted upwards into a sitting position. Once the body 110 has been fully inflated (as seen in FIG. 3), at 210 the first user 10 will be in a sitting position and can then get up from the body 110 under his or her own volition or with the assistance of the second user. It should be noted that in one embodiment, the device 100 can also be used solely as an inflatable chair.
