Appl. No.:

7/365535

Inventors:

Walter G. Lockard - Elyria OH
Allen J. Boris - Elyria OH
Wieslaw Kosc - North Royalton OH

Assignee:

Invacare Corporation - Elyria OH

International Classification:

A61G 502

US Classification:

2802501

Abstract:

A pair of identical side frames (A) are each made up of a pair of generally L-shaped tubular members which are welded together. A reinforcing tube (30) is slidably received within a forward portion (14) of each side frame to strengthen an interconnection with a front wheel assembly mounting bracket (32) with mechanical fasteners. A swing away leg rest mounting bracket (50) is also connected with the forward tubular portion and reinforcing tube for selectively supporting a swing away leg rest assembly thereon. A folding mechanism (D) includes a pair of pivotally connected seat support structures (100). The seat support structures include seat side supports (102) which have a longer free end (106) and shorter free end (108), cross members 104 and fittings (120). Circumferentially disposed grooves (124) are offset in such a manner that the seat support structures are interchangeable. An arm rest assembly (F) is releasably connected with the side frames with brackets (162, 174) such that the arm support structure can be selectively removed from the brackets or pivoted about one of them.

US Classification:

280 42

Abstract:

Wheelchair side frames (A) include forward and rearward side frame fortions (10, 12) which are telescopically interconnected such that the length of the side frames is selectively adjustable. A cross brace folding assembly (B) interconnects the side frames and selectively moves the side frames between folded and open configurations. The cross brace mechanism includes a pair of cross brace members (30, 32) which are pivotally interconnected (34) and which are each adjustable in length to adjust the width of the wheelchair in the open configuration without adjusting the height of the seat (100). A pair of rear seat support members (114) are telescopically mounted on posts (112) of the rear frame and are interconnected with stand-off members (120) for supporting a seat back portion (110). The stand-off members hold the seat back away from the rear seat support members such that the clamps from orthopedic braces and appliances may be freely mounted therealong. A front foot rest assembly (D) includes a foot rest supporting member (174) which adjusts up/down, fore/aft, and the degree of tilt.

Abstract:

Wheelchair side frames (A) include forward and rearward side frame portions (10, 12) which are telescopically interconnected such that the length of the side frames is selectively adjustable.

US Classification:

280 30

Abstract:

A stroller base (A) detachably receives a seat structure (B) therein. The base includes forward wheel assemblies (12), rearward wheel assemblies (14) for rollably supporting the base, and wheel lock structures (60) for selectively locking the rear wheels against rotation. An upper base frame portion (20) is collapsable to a folded position (FIG. 3) and raiseable to a seat structure receiving position (FIG. 2). The upper base frame portion includes a channel guide (30) having a transverse slot (38) therein. The detachable seat structure includes a seat frame (80) with a plurality of patient supporting pads (90, 92, 94, 96) adjustably mounted thereon. Handles (84) selectively enable an attendant to lift a rearward portion of the detachable seat structure. A transverse seat frame member (88) is selectively received in the channel guide slot as the seat structure is positioned thereon and selectively lifted out of the channel guide slot as the seat is lifted therefrom. The seat frame adjustably mounts a footrest structure (140) and a roller (130) at a forward, lower end thereof.

Abstract:

A convertible wheelchair permits change over from an attended wheelchair arrangement to a self propelled wheelchair arrangement. The wheelchair accommodates both lateral and longitudinal dimensional changes. Further, the seat can pivot relative to the frame, as well as permitting a seat back to tilt relative to the seat portion. In the attended wheelchair arrangement, the rear wheels are simultaneously locked.
