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.

Description

BACKGROUND OF THE INVENTION

Most present-day outdoor chairs are without any provided shade. An object of the present invention is to provide an exstenable canopy which may be retained on or removed from the chair and folded into a compact configuration for convenient carrying, and which is constructed to be simply adjustable so that the canopy may be set to any desired height according to the desires of the user, and to any desired angle appropriately to shield the user from the sun.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENT

The canopy, of the invention, is more clearly shown in FIGS. 1 and 3 include a back frame having first and second spaced and parallel elongated tubular members 4 and 5. Frictional coupling members are provided so that the frame may be angled at a frontward position FIG. 3 elongated tubulars are inserted inside casing members to support canopy.
The canopy also includes a frame having first and second spaced and parallel elongated side members 4 and 5. The canopy frame is pivotally coupled to the cross members of the frame through frictional coupling members 3 so that the canopy frame may be at a frontward position held in that position by the frictional coupling members.
As shown in FIG. 1 the canopy may be removably mounted on a wheelchair with the side members. The tubular members are attached to the frame of the wheelchair by appropriate bar clamps.
The invention provides, therefore, a simple removable canopy which is frictionally held in the position to which it is set.
It will be appreciated that while a particular embodiment of the invention has been shown and described, modifications may be made. It is intended in the claims to cover all modifications which come within the spirit and scope of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective representation of one embodiment of the collapsible chair and canopy combination of the invention;
FIG. 2 is a view like FIG. 1, but with the canopy frame turned down prior to folding the chair to its carrying position;
FIG. 3 is a perspective view, like FIG. 1, but with the fabric covers of the chair removed to reveal the tubular frame in greater detail;
FIG. 4 shows a side view of the cover with side flaps an upright tubular member;
FIG. 5 is a perspective view of the canopy assembly of the invention.

Claims

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.
