## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation in part of U.S. application Ser. No. 11/581,288, filed Oct. 16, 2006, now abandoned the entire specification of which is incorporated herein by reference.


FIELD OF THE DISCLOSURE
The present disclosure relates generally to leg elevating devices, systems, and methods, in particular, a device, system, or method to elevate the legs from an angled position to a horizontal position.
BACKGROUND
Movement of limbs can be challenging for persons with disabilities, the elderly, or persons recovering from recent surgery when those persons transfer from one location to another, whether independently or assisted. For example, in the case of persons with mobility impairments, it is often quite difficult to get into and out of a bed without assistance.
Several efforts have been made to alleviate the problem associated with getting into and out of a bed without assistance. For example, devices equipped with a hoop and pulley-system have been developed so that a person can put their feet into the hoop and pull their legs to bed level. Similar devices are also available where the hoop is attached to a rod so that the person can put their foot into the hoop and pull the rod up so that the foot is level with the bed. These devices, however, have drawbacks such as limited portability in the case of the pulley system, and limited physical capabilities of the person operating the device in the case of the rod and hoop system. Additionally, in both cases the devices require upper and lower body strength to pull the legs upwards to bed level. In cases where persons are disabled or recovering from recent surgery, the persons may not have the strength necessary to operate the devices.
Accordingly, it would be desirable to provide a portable leg elevating device for lifting the legs of a person without requiring substantial upper and lower body strength.

In addition, in some embodiments, the base platform 104 can have a length 109 ranging from twenty (20) inches to forty (40) inches and a height 111 ranging from one-half (0.5) inch to two (2) inches. Also, in some embodiments, the base platform 104 can include a receiving member to receive a retractable handle to increase the portability of the leg elevating device 100, as discussed herein.
In addition, in various embodiments, the base platform 104 can include at least one wheel 106 coupled to the base platform 104 to make the leg lifting device 100 easily movable and/or portable. In some embodiments, the base platform can include at least four wheels 106 coupled to the base platform 104. In some embodiments, the wheels 106 can be in the form of a caster assembly where a small wheel 106 has the ability to swivel and is coupled to the base platform 104 to make the leg elevating device 100 easy to move. In addition, in such embodiments, the wheels 106 can include a brake mechanism 113 to lock the wheels 106 into place.
In some embodiments, the base platform 104 can include a location where a handle 108 can be releasably and/or pivotably connected on one end 112 of the base platform 104. In such embodiments, the handle 108 can be used to push and/or pull the leg elevating device 100 into position to use the leg elevating device 100. For example, the handle 108 can be used to position the leg elevating device 100 next to a bed. To facilitate the positioning of the leg elevating device 100 using the handle, in some embodiments the handle 108 can move (e.g., pivot and/or rotate) relative the base platform 104 as shown with arrow 121.
Additionally, the handle 108 can be used to move the leg elevating device 100 out of the way when the leg elevating device 100 is not in use. For example, the handle 108 can be used to push and/or pull the leg elevating device 100 to the head of a bed so that a user will not stumble on the leg elevating device 100 while getting out of a bed. In various embodiments, the handle 108 can also be used to lock and/or unlock the wheels 106 to fix the leg elevating device's 100 position either while in use and/or while the leg elevating device 100 is not being used.
As illustrated in FIGS. 1A-1C, in one embodiment, the handle 108 can be attached to the leg elevating device 100 at a site 110 on one end 112 of the base platform 104. In one embodiment, the handle 108 can be releasably coupled to the base platform 104.

In various embodiments, the handle 108 can be attached to the leg elevating device 100 at a second end 114 of the leg elevating device 100. In some embodiments, the leg elevating device 100 can have more than one site 110 where the handle 108 can be attached to the leg elevating device 100.
The handle 108 can releasably couple to the leg elevating device 100 in a number of ways. For example, the handle 108 can releasably couple to the leg elevating device 100 by providing a threaded opening in the base platform 104 and a complimentary threaded end on the handle 108. Other ways to releasably couple the handle 108 to the leg elevating device 100 are also possible.
In one embodiment, the handle 108 can be a circular rod with a height ranging from thirty (30) inches to forty-two (42) inches. The handle 108 can also have different cross-sectional shapes such as a square, oval, ellipse, or triangle. In addition, in some embodiments the handle 108 can be formed of a metal, metal-alloy, glass, wood, plastic, or the like. The handle 108 can also be formed of different materials.
FIG. 1E illustrates an elevational plan view of an embodiment of the leg elevating device 100 according to the present disclosure. In some embodiments, the front wheels 119 positioned near the second lift 118 can be coupled to a lockable bracket 121. In some embodiments, the lockable bracket 121 can pivot around a pivot point so that the front wheels 119 move from a first wheel position 123 to a second wheel position 125. In some embodiments, the first wheel position 123 can be when the front wheels 119 are underneath the base platform 104. In some embodiments, the second wheel position 125 can be when the front wheels 119 are adjacent the base platform 104. In some embodiments, the back set of wheels 131 can be coupled to the base platform 104 such that the back set of wheels 131 are of approximately equal height to the front set of wheels 119 when in the first position 123.
As illustrated in FIG. 1E, when the front wheels 119 are in the second wheel position 125 the leg elevating device 100 can be tilted so that the front wheels 119 support the weight of the leg elevating device 100, and the leg elevating device 100 is easily moveable.
As discussed herein, the handle 108 can move (e.g., pivot and/or rotate) relative the base platform 104. In some embodiments, the handle 108 can move between an upright position where the handle 108 can be perpendicular the base platform, as shown in FIGS. 1A-1C, and a horizontal position, as shown in FIG. 1E, where the handle 108 is parallel the base platform 104. In some embodiments, the handle 108 can be retractable into a receiving member 127 positioned adjacent a base platform 104 member 129. In some embodiments, the handle 108 can be retracted into the receiving member 127 to at least one fixed position when the handle 108 is in the horizontal position. In some embodiments, the handle 108 can be retracted completely into the receiving member 127 to allow the leg elevating device 100 to be stored.
As discussed herein, a front set of wheels 119 can be coupled to a lockable bracket 121 that pivots around a pivot point. In some embodiments, the leg elevating device 100 includes the front set of wheels 119 coupled to the lockable bracket 121 and the handle 108 that can be retracted into a receiving member 127 when the handle 108 is in a horizontal position. In some embodiments, when the front set of wheels 119 are in the second position 125, the lockable bracket 121 can lock the front set of wheels 119 into the second position 125, and the handle 108 can be retracted to a fixed position in the receiving member 127. As illustrated in FIG. 1E, in some embodiments, the leg elevating device 100 can be portable, and can be transported between residences while a user is traveling.
In some embodiments, the leg elevating device 100 can include power driven wheels 106 (e.g., electrically powered) controlled via a remote control device. In such embodiments, the driving mechanisms for the wheels 106 are typically electric motors actuated by servos, belts, and gears. Embodiments using power driven wheels 106 can move the leg elevating device 100 so that it abuts the side of a bed while the leg elevating device 100 is in the second horizontal position, making it easier for the user to slide their lower legs directly onto a bed.
As discussed herein, the leg elevating device 100 can have a leg support platform 102 that moves between a first horizontal position 103, an angled position 105, and a second horizontal position 107. In one embodiment, the leg support platform 102 is coupled to the base platform 104 via a first lift 116 and a second lift 118. As used herein, “lift” refers to a device designed to raise something. In some embodiments, the leg elevating device 100 can include additional lifts. For example, if the leg elevating device were equipped with an additional leg support platform to lift the left leg and right leg separately, the additional leg support platform could be moved between the horizontal and angled positions using two additional lifts.
In addition, in some embodiments, the leg elevating device 100 can include additional lifts depending on the shape of the leg support platform 102. For example, in some embodiments, the leg support platform 102 can have a circular shape. In this example, the leg elevating device 100 can include four lifts positioned in a diamond shaped pattern so that the leg support platform 102 is well-balanced from each side. Other combinations of leg support platform 102 shapes and the number of lifts are also possible. In addition, the leg support platform 102 can also vacillate in a controlled manner, using, for example, a hydraulic pump coupled to an electric motor. Other ways to control the vacillation movement are also possible.
In some embodiments, the leg support platform 102 can be coupled to the first lift 116 and second lift 118 such that the leg support platform 102 can vacillate around a center axis 133 of the leg support platform 102 that runs between the first lift 116 and the second lift 118 of the leg support platform 102. In such embodiments, the leg support platform 102 can be coupled to the first and second lift 116, 118 using hinges to limit the range of vacillation of the leg support platform 102. For example, the hinges can allow for a side of the leg support platform 102 to move downward one (1) inch, while the opposite side of the leg support platform 102 moved upward one (1) inch. Other values for the range of vacillation are also possible. In some embodiments, the range of vacillation can depend on the depth of the leg placement marker on the layer of material overlying the leg support platform 102, as discussed herein with respect to FIG. 1D. Other methods of coupling the first and second lift 116, 118 to allow for vacillation around a center axis 133 are also possible.
As illustrated in FIGS. 1A-1C, the first lift 116 and second lift 118 can be coupled to the leg support platform 102 and the base platform 104. In one embodiment, the first lift 116 and second lift 118 can be coupled to the leg support platform 102 using a mechanical linkage between the leg support platform 102 and each of the first lift 116 and second lift 118 independently. Embodiments using a mechanical linkage allow the leg support platform 102 to move from a first horizontal position 103 as shown in FIG. 1A to an angled position 105 as shown in FIG. 1B. Therefore, in such embodiments, the mechanical linkage can allow the leg support platform 102 to move from an angle of approximately zero (0) degrees relative to the base platform 104 when the leg support platform is in the first horizontal position 103, to an angle of approximately forty-five (45) degrees relative to the base platform 104 when the leg support platform 102 is in the angled position 105, and to an angle of approximately zero (0) degrees relative to the base platform 104 when the leg support platform 102 is in the second horizontal position 107.
FIGS. 1A-1C illustrate various embodiments of the leg elevating device 100 where the first and second lift 116, 118 can move from a first position as shown in FIG. 1A to a second position as shown in FIGS. 1B and 1C pneumatically. For example, the first and second lift 116, 118 can include a pneumatic cylinder in each of the first lift 116 and second lift 118, capable of developing pneumatic pressure to support the leg support platform 102 at a desired height and angle. In addition, in this embodiment, the first lift and second lift 116, 118 can include means for selectively releasing the pneumatic pressure and storing the resulting pneumatic fluid flow outside the pneumatic cylinder, allowing the user to set the height of the first and second lift 116, 118, and then locking the first and second lift 116, 118 into the intended position. In some embodiments, the pneumatic cylinders inside the first and second lift 116, 118 can have a thirty (30) inch stroke and a pushing force of approximately three hundred (300) pounds. In various embodiments, hydraulic cylinders having a similar capability can be used.
In some embodiments, the leg elevating device 100 can include a hydraulic cylinder in each of the first and second lift 116, 118, as discussed herein, as well as a power system. For example, the hydraulic cylinder can be controlled by an electrically energized hydraulic power system including an electric motor 120 and control box 122 to cause the first and second lifts 116, 118 to move upwardly and downwardly from the first position to the second position, as discussed herein. Other control and actuation systems can be used in various embodiments as desired such as an electric motor without the use of hydraulic or pneumatic cylinders, for example.
In some embodiments, the electric motor 120 can be a motor powered by at least one rechargeable battery. In some embodiments, a charger can be included with the leg elevating device 100, such that the charger can be releasably coupled to the leg elevating device 100 to charge the rechargeable battery. In some embodiments, the charger can be of an appropriate size to be locatable under furniture. In such embodiments, the leg elevating device 100 can be guided back to the charger using a remote device, as discussed herein. In some embodiments, the leg elevating device 100 can be programmed to return to the charger automatically when the at least one rechargeable battery reaches a defined lower limit of stored energy.
In some embodiments, the electric motor 120 can be a battery powered motor. Additionally, in various embodiments, the electric motor 120 can be powered via an electrical connection to an electrical wall socket. Other types of motors can also be used.
As discussed herein, the leg support platform 102 can move from a first horizontal position 103, to an angled position 105, and to a second horizontal position 107 as illustrated in FIGS. 1A-1C. As shown in FIG. 1A, when embodiments of the leg elevating device 100 are in the first horizontal position 103 the height 124 of the leg elevating device 100 can range from four (4) inches to ten (10) inches. In various embodiments, as the first lift 116 moves from the first position as shown in FIG. 1A to the second position as shown in FIG. 1B, the leg support platform 102 goes from a first horizontal position 103 to an angled position 105 relative the base support platform 104.
As shown in FIG. 1B, embodiments of the leg elevating device 100 can have a leg support platform 102 in an angled position. In some embodiments, the angle of the leg support platform 102 relative the base platform 104 can be in the range of thirty-five (35) degrees to fifty-five (55) degrees.
In some embodiments, the second lift 118 can move from a first position, as shown in FIGS. 1A and 1B to a second position, as shown in FIG. 1C. As the second lift 118 moves from first position to the second position, embodiments of the leg elevating device 100 can have the leg support platform 102 at the second horizontal position 107, as shown in FIG. 1C. In such embodiments, the height 124 of the leg elevating device 100 when in the second horizontal position 107 can range from twenty-five (25) inches to thirty-five (35) inches. Embodiments, however, are not limited to these examples.
In some embodiments, the leg elevating device 100 is configured to move from the first horizontal position 103 as shown in FIG. 1A to the angled position 105, shown in FIG. 1B at a rate of about two (2) to three (3) degrees for every one (1) inch raised in height. Similarly, in some embodiments, the leg elevating device 100 can move from the angled position 105, shown in FIG. 1B, to the second horizontal position 107, shown in FIG. 1C, at a rate of about two (2) to three (3) degrees for every one (1) inch raised in height. In addition, in various embodiments, the entire cycle time with which the leg elevating device 100 can move from the first horizontal position 103, to the angled position 105, to the second horizontal position 107, and back to the first horizontal position 103 can range from three (3) minutes to five (five) minutes. Exemplary speeds for the leg elevating device, therefore, can range from nine (9) inches per minute to thirty-one (31) inches per minute.
