8 Claims, 6 Drawing Figures PATENTEB 10 INVENTOR JAMEE A. 660246544 LEG SUPIORTING DEVICE The present invention relates to a device for supporting a users leg (particularly a leg in a cast) in a substantially horizontal position while the user is seated.

BACKGROUND OF THE INVENTION Anyone who has worn a leg cast is familiar with the problems and discomfort encountered while wearing such a cast in a seated position. T o alleviate such discomfort, individuals wearing leg casts typically rest their legs on footstools, or prop them with pillows, books, etc. Unfortunately, however, stools or propping devices of the proper height are not always available at each time and place an individual is seated.

The leg supporting device of the present invention is adapted to be worn around the users leg cast so that it is always available when the user desires to be seated. The device includes an ankle engaging member adapted to be secured around the user's ankle or lower calf, and a stanchion rotatably connected to the ankle engaging member for movement between a supporting position and'a stored position on the users leg.

DESCRIPTION OF PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2 of the drawing, the leg supporting device 10 shown therein is seen to comprise a generally U-shaped ankle engaging member 12 and a stanchion 14.

The stanchion 14 includes a pair of

parallel support bars

16, 16, each of which has one of its ends rotatably connected to one side of the ankle engaging member 12. The other end of each support bar 16 is integrally connected to a generally U-shaped base member 18 which serves a dual function. When the user is seated and the device 10 is employed to support his leg in a substantially horizontal position (solid line position of the device in FIG. 1), the base serves as a-pedestal for the device.

- When the device is no longer needed as a support (e.g., when the user is standing or moving around), the user rotates the stanchion 14 to a position adjacent his leg (phantom line position in FIG. 1). In this position, the U-shaped base 18 partially encircles the upper calf of the users leg, thereby permitting the

support bars

16, 16 to straddle his leg cast 20.

A strap 21 is riveted or otherwise suitably secured to the free ends of the ankle-engaging member 12 for securing the device around the users ankle or lower calf (as shown in FIG. 1).

The ankle-engaging member 12 is preferably made of two generally arcuate sides l7, 17 connected by a hinge 19. By virtue of this construction, the member 12 is adapted to fit around ankles or lower calves of vari- OUS SIZCS.

Alternatively, the ankle-engaging member may be a single U-shaped member.

The

ends

23, 23 of the base member 18 are bent slightly inwardly to better engage the portion of the cast around which it fits. A rubber cover 22 is preferably provided around the lower edge of the base member 18 to prevent the member from sliding on the floor when the device is in use, and to prevent damage to the floor or other property.

As best shown in FIG. 2, the stanchion 14 is rotatably connected to the ankle-engaging member 12 by means of

bolts

25, 25 which extend through the

sides

17, 17 of the ankle-engaging member 12 and through

holes

26, 26 in the

free ends

28, 28 of the support bars I6, 16. Rotational movement of the stanchion 14 relative to the ankle-engaging member 12 is limited by means of outwardly struck

flanges

30, 30 on the sides of the ankle-engaging member.

An elongated slot 32 is provided in each support bar 16 directly adjacent the hole 26 through which the bolt 25 passes. The

slots

32, 32 are narrower than the diameter of the

holes

26, 26 and the

bolts

25, 25 are flattened to ride in the slots when the stanchion is rotated to its non-supporting position (FIG. 4 position; phantom line position in FIG. 1).

With reference to FIG. 3, it will be noted that when the stanchion 14 is in the leg supporting position (position shown in FIGS. 1, 2 and 3) and

bolts

25, 25 cannot ride in the

slots

32, 32 because the slots are narrower than the diameter of the bolt shank.

Spaced

holes

35, 35 may be provided along the length of each slot 32 to permit the effective supporting height of the stanchion to be adjusted.

When the stanchion 14 is turned 90 in a clockwise 7 direction (as viewed in FIGS. 1-4) to the non-supporting position (FIG. 4), the bolt shank 25 can ride in the slot 32 and the

support bars

16, 16 may be slid downwardly on the users leg until the base member 18 is located in a position comfortable to the user (i.e., well below the knee joint). Of course, when the device 10 is employed in conjunction with a full leg cast, it will not be necessary to employ this sliding feature of the device.

In use, the ankle-engaging member 12 is secured around the ankle or lower calf portion of the users cast 20 by means of strap 21. When the device 10 is not being employed to support the users leg, the stanchion 14 is rotated tothe position shown in phantom lines in FIG. 1. In this non-supporting position, the U-shaped base member 18 engages and partially encircles the upper calf portion of the users leg below the knee joint, thereby permitting the support bars l6, 16 to straddle the calf of the users leg. Thus, the stanchion will not inhibit the users mobility.

When the user sits down and desires to support his leg in a horizontal position (FIG. 1), he simply slides the

support bars

16, 16 upwardly along his leg until one of the sets of

holes

26 or 35 engages the

flattened bolt shanks

25, 25.

The stanchion is then rotated approximately 90 in a clockwise direction (as viewed in FIG. 1) until the upper side edge of

thesupport bars

16, 16 engage the struck out

flanges

30, 30 on the ankleengaging member 12. In this supporting position of the device 10 (FIGS. 1 and 2), the U-shaped base 18 of the stanchion l4 rests on the floor and acts as a pedestal or foundation for the device. As best shown in FIG. 3, each of the

flattened bolt shanks

25, 25 is so positioned in its associated hole 26 (or 35) that it cannot enter the narrower slot 32 adjacent the hole. The device 10 thus serves as a sturdy support for the users leg.

When the user desires to rise, he simply rotates the stanchion 14 approximately 90 in a counter-clockwise direction (as viewed in FIG. 1) until each of the flattened bolt shanks 25 registers with its associated slot 32. If the user is wearing a half-leg cast, he may then push the

support bars

16, 16 downwardly until the base member 18 is comfortably located below his knee joint. It will be noted that when the stanchion 14 is rotated to this non-supporting position (phantom line position in FIG. 1), the U-shaped base member 18 will engage and partially encircle the upper calf portion of the users leg and the

support bars

16, 16 will straddle his calf. The flattened bolt shank 25 in the slot 32 will prevent rotational movement of the stanchion.

The user'may thenlie down or-move around without interference by the device 10. When the user next needs support for his leg, the device 10 will be available.

The slot 32 and flattened bolt shank 25 arrangement of the leg support depicted in FIGS. 1-4 are not essential, and non-adjustable supports may be made in accordance with the teachings of this invention.

It is also to be understood that structure other than the struck out

flanges

30, 30 on the ankle-engaging member 12 may be provided for limiting rotational movement of the stanchion.

FIGS. and 6 show two modified leg supports which are not adjustable (i.e., have no slots or flattened bolt shanks), and are provided with different means for limiting rotational movement of the stanchion.

Referring to FIG. 5, it will be noted that the ankleengaging member 48 is provided with a struck out flange 50 on each side thereof. The outwardly struck flange 50 is adapted to cooperate with a lip 52 provided on the upper end of the support bar 54. This structure limitsclockwise rotational movement of the stanchion support bar 54 (as viewed in FIG. 5).

It will be noted thatno adjustment slots (like slots 32 of the device are provided in the support bar 54, and the bolt 56 which secures the support bar to the ankle-engaging member 48. It will also be noted that the ankle strap 58 is looped around a slot 60 provided in the upper, free ends of the ankle engaging member 48 rather than riveted thereto as is the strap 58 shown in the FIG. l-4 embodiment.

The ankle-engaging member shown in FIG. 6 employs a hexagonal nut which acts as an abutment head to limit clockwise movement of the support bar 72.

Of "course, it is contemplated that various'rnodiflcations may be made to the regular support devices depicted in the drawings and described above without departing from the spirit and scope of the invention. For example, the .U-shaped base 18, which doubles as an upper calf-engaging member, may be rotatably mounted on the lower ends of the support bars 16, and may be provided with a strap (like strap 21). The ankle-engaging member 12 may then be rigidly connected to the other ends of the support bars. Employing this arrangement, the stanchion 14 is rotated relative to the upper calf-engaging member, rather than the ankleengaging member. Such a structure may be desirable, for example, when a leg cast is worn which does not extend down to the users ankle.

It is alsocontemplated that structure other than the slotted support bars 16 and flattened bolt shanks 25 may be provided for rendering the stanchion slidable relative to the ankle-engaging member 12 (FIGS. l-4- embodiment).
