ABSTRACT:
An extendable leg rest assembly (20) having a footrest device (26) for a wheelchair including a mounting assembly (22) for mounting the leg rest assembly (20) to a frame (10) of the wheelchair. An elongated shaft (40) is pivotally coupled to the mounting assembly (22) to enable pivotal movement of the shaft (40) about a first pivotal axis (45) between a lowered position and a raised position. An elongated extension member (50) is telescopically mounted on the shaft (40) for reciprocating movement relative thereto. Pivotally coupled between the mounting assembly (22) and the elongated extension member (50) is a linkage (28). The linkage (28) pivots about a second pivotal axis (75) on the mounting assembly (22) spaced forwardly from the first pivotal axis (45). Upon pivoting of the shaft member (40) upwardly about the first pivotal axis (45), the linkage (28) causes the extension member (50) to slide outward on the shaft member (40 ) away from the mounting assembly (22) in response to the pivotal movement of the linkage (28) about the second pivotal axis (75).
