Abstract
Abstract A device for supporting an individual''s leg in a substantially horizontal position when the individual is seated. The device is particularly designed to support a leg in a cast, and is adapted to be worn on the cast around the user''s leg when the device is not in use. The device includes a generally U-shaped 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. The stanchion includes a pair of parallel support bars, each of which mounts the ankle engaging member at one end thereof. The other end of each support bar is integrally connected to another generally U-shaped member which acts as a base for the stanchion when the device is in use, and which partially encircles the upper calf portion of the user''s leg when the device is not in use. Suitable stop means are provided on the ankle engaging member and the upper ends of the stanchion for limiting rotational movement of the stanchion relative to the ankle engaging member. The support bars are preferably slotted to permit the stanchion to be adjusted to a comfortable position on the user''s leg when the device is not in use.

Claim 1
Independent Claim
83 words
An improved leg supporting device comprising: an ankle engaging member adapted to receive the ankle or lower calf of a user''s leg; a stanchion connected at one end thereof to said ankle-engaging member; a base member, connected to the other end of said stanchion; said stanchion comprising a pair of spaced, substantially parallel support bars; means pivotably connecting one end of each support bar to said ankle-engaging member; and means for limiting pivotal movement of said stanchion relative to said ankle engaging member.
Claim 2
Dependent Claim
83 words
An improved leg supporting device comprising: an ankle engaging member adapted to receive the ankle or lower calf of a user''s leg; a stanchion connected at one end thereof to said ankle-engaging member; a base member, connected to the other end of said stanchion; said stanchion comprising a pair of spaced, substantially parallel support bars; means pivotably connecting one end of each support bar to said ankle-engaging member; and means for limiting pivotal movement of said stanchion relative to said ankle engaging member.
Claim 3
Dependent Claim
38 words
An improved leg supporting device according to claim 1, wherein said pivotal limiting means comprises flange means struck from said ankle engaging member and adapted to be contacted by said one end of each of said support bars.
Claim 4
Dependent Claim
39 words
An improved leg supporting device according to claim 1, wherein said pivotal limiting means comprises an abutment head mounted on said ankle engaging member and adapted to be contacted by said one end of one of said support bars.
Claim 5
Dependent Claim
44 words
An improved leg supporting device according to claim 1, wherein said means pivotably connecting said support bars to said ankle engaging member comprises a bolt extending through said ankle engaging member and a hole in said one end of each of said support bars.
Claim 6
Dependent Claim

An improved leg supporting device according to claim 4, and further comprising means for adjusting the position of said ankle engaging member relative to the length of said stanchion; said adjusting means comprising flattened side edges on each of said bolts, and an elongated slot in each of said support bars; each of said slots adjoining said hole in the upper end of its support bar and being adapted to receive said bolt when said bolt is disposed with its flattened sides parallel to the side edges of said slot.
Claim 7
Dependent Claim
46 words
An improved leg supporting device according to claim 5 and further comprising at least one height adjustment hole along the length of each of said slots in said support bars for shortening the effective height of said stanchion when the leg supporting device is in use.
Claim 8
Dependent Claim
84 words
An improved leg supporting device comprising: a leg-engaging member adapted to be secured on a portion of a user''s leg; an elongated support member connected at one end thereof to said leg engaging member; and means pivotably connecting said one end of said support member to said leg-engaging member; whereby said support member may be moved between a supporting position wherein it supports a user''s leg in a substantially horizontal position and a non-supporting position wherein it is disposed adjacent to the user''s leg.
Claim 9
Dependent Claim
84 words
An improved leg supporting device comprising: a leg-engaging member adapted to be secured on a portion of a user''s leg; an elongated support member connected at one end thereof to said leg engaging member; and means pivotably connecting said one end of said support member to said leg-engaging member; whereby said support member may be moved between a supporting position wherein it supports a user''s leg in a substantially horizontal position and a non-supporting position wherein it is disposed adjacent to the user''s leg.
Claim 10
Dependent Claim
