29 Chain 37 passes over guide 301, which functions to keep chain 37 in alignment.
28 Lower bolt hole 42A is aligned and connected with engaging orifice 45A at the first end of ratchet 41.
27 Ratchet 41 is a commercially available ratchet which can be purchased at most hardware stores.
26 Axle 36 is mounted to frame 31 by inserting axle 36 through each of openings 38 in frame 31.
25 Frame 31 is provided with finger like protrusions 31A for engagement with brackets 22 of support means 20.
24 In order to facilitate use of the wheelchair without the need for remodeling of buildings, it is important that the total width of the wheelchair when support means 20 is engaged with propulsion means 30 be less wide than a standard door.
23 The wheelchair of the present invention includes three component parts: a propulsion means, a mobile support means provided with means for receiving the legs of a chair, and a chair.
22 In order to overcome the problems described above, occupant propelled wheelchairs which use a rowing mechanism to provide propulsion have been proposed.
21 As is well known in the art, a conventional wheelchair has two large, rear wheels on either side of a seat while small caster wheels are positioned on either side of a footrest.
20 This invention relates to an occupant propelled wheelchair comprising three separable and interchangeable components.
