Abstract

An extendable elevating leg rest assembly for a wheelchair includes a support tube connected to the wheelchair. A first gear member is fixed to the support tube. an extendable strut, which includes a hollow upper strut member pivotally connected to the first gear member and a Lower strut member slidably received in the upper strut member, pivots about the first gear member between a lowered position and an elevated position. An adjustable foot rest assembly is releasably clamped to the lower strut member. The leg rest assembly also includes a mechanism for extending the foot rest in reaction to the strut being pivoted toward the elevated position. The extending mechanism includes a second gear member, a drive link, and a follower link.
The second gear member is rotatably mounted on the upper strut member and is in meshing engagement with the first gear member so that the second gear member rotates when the strut is pivoted about the first gear member. The drive link has a fixed end fixed to the second gear member and a free end pivotally connected to one end of the follower link. The other end of the follower link is connected to the lower strut member. When the strut is pivoted from the lowered position to the raised position, the second gear member is caused to rotate, which pivots the drive link. Pivoting the drive link causes the follower link to extend the lower strut member out of the upper strut member.
