Wheel chair canopy

Abstract

An adjustable canopy for a wheelchair, and the like, which includes a tubular frame which may be extended to one angular position, and which may be coupled to a tubular back frame of the chair so that the canopy may be set to one front elevation.

1 . A canopy for a chair, said chair including a pair of spaced and parallel upright tubular side members, and said canopy assembly comprising: a U-shaped frame having first and second elongated side members and an elongated cross member at the forward end thereof; third and fourth elongated side members to be telescopically and removably in respective ones of said tubular side members of said chair; a tubular cross member secured to the upper ends of said third and fourth elongated side members; first and second frictional coupling assemblies for respectively coupling said first and second side members of said U-shaped frame members to said tubular cross members to permit said frame to be turned and set to a frontward angular position, third and fourth frictional coupling assemblies for respectively coupling said third and fourth elongated side members to said tubular side members and to be set at a frontward linear position with respect thereto, and to permit said frame to be removed from said tubular side members, said third and fourth frictional coupling assemblies mounted in press fit in the end of the corresponding one of said third and fourth elongated side members, radially acting compressing member mounted on the lower end of the corresponding one of said third and fourth elongated side member in frictional engagement with the inner surface of the corresponding one of said tubular side members of said chair, said compressing member having a tubular upper portion to be received in press fit with said frictional coupling when the canopy is removed from the chair to enable said coupling to be held on the end of the corresponding one of said third and fourth side members upon such removal of the canopy from the chair. 
   
   
       2 . The canopy assembly defined in  claim 1 , in which said first and second frictional coupling assemblies each includes: said tubular cross member from one end thereof to the other. 
   
   
       3 . The canopy assembly defined in  claim 1 , in which said chair is a wheelchair. 
   
   
       4 . The canopy assembly defined in  claim 1 , in which includes a fabric canopy supported on said rectangular frame appropriately to shield the user from the sun. 
   
   
       5 . The canopy assembly defined in  claim 5 , in which said fabric canopy includes a back flap. 
   
   
       6 . The canopy assembly defined in  claim 5 , in which said fabric canopy includes a pair of side flaps. 
   
   
       7 . The canopy assembly defined in  claim 5 , in which said side flaps are adaptable to be folded inward of the canopy when not in use, and which includes fastener means for holding the canopy side flaps in folded inward position.
