Abstract
Abstract An adjustable canopy for a wheel chair, beach chair and the like, which includes a tubular frame which may be turned and set to any desired angular position, and which may be coupled to a tubular back frame of the chair in frictional relationship to be slidable in the back frame so that the canopy may be set to any desired elevation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
327 words
A canopy assembly 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 received 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 member to said tubular cross member to permit said frame to be turned and set to any desired angular position; third and fourth frictional coupling assemblies for respectively coupling said third and fourth elongated side members to said tubular side members of said chair to permit said frame to be moved linearly with respect to said tubular side members and to be set at any desired 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 each including a bushing mounted in press fit in the end of the corresponding one of said tubular side members of said chair for receiving the corresponding one of said third and fourth elongated side members, and a radially acting spring member mounted on the lower end of the corresponding one of said third and fourth elongated side members in frictional engagement with the inner surface of the corresponding one of said tubular side members of said chair, said spring member having a tubular upper portion to be received in press fit with said bushing when the canopy is removed from the chair to enable said bushing 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.
Claim 2
Dependent Claim
327 words
A canopy assembly 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 received 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 member to said tubular cross member to permit said frame to be turned and set to any desired angular position; third and fourth frictional coupling assemblies for respectively coupling said third and fourth elongated side members to said tubular side members of said chair to permit said frame to be moved linearly with respect to said tubular side members and to be set at any desired 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 each including a bushing mounted in press fit in the end of the corresponding one of said tubular side members of said chair for receiving the corresponding one of said third and fourth elongated side members, and a radially acting spring member mounted on the lower end of the corresponding one of said third and fourth elongated side members in frictional engagement with the inner surface of the corresponding one of said tubular side members of said chair, said spring member having a tubular upper portion to be received in press fit with said bushing when the canopy is removed from the chair to enable said bushing 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.
Claim 3
Dependent Claim
76 words
The canopy assembly defined in claim 1, in which said first and second frictional coupling assemblies each includes: a rod extending coaxially through said tubular cross member from one end thereof to the other, a pair of bushings extending into the respective end of said tubular cross member; and a pair of nuts threaded on the respective ends of said rod to tighten the ends of said first and second elongated side members against said bushings.
Claim 4
Dependent Claim
15 words
The canopy assembly defined in claim 1, in which said chair is a beach chair.
Claim 5
Dependent Claim
15 words
The canopy assembly defined in claim 1, in which said chair is a wheel chair.

Claim 7
Dependent Claim
16 words
The canopy assembly defined in claim 5, in which said fabric canopy includes a back flap.
Claim 8
Dependent Claim
18 words
The canopy assembly defined in claim 5, in which said fabric canopy includes a pair of side flaps.
Claim 9
Dependent Claim
40 words
The canopy assembly defined in claim 7, in which said side flaps are adaptable to be folded over the top of the canopy when not in use, and which includes fastener means for holding the side flaps in folded-over position.
