Abstract

A sun shade is disclosed which is readily convertible from a ground supported shade to a chair-back supported shade for use while sunbathing. The sun shade includes a U-shaped support member having the bottom portion of the U as a rearward support for the shade and the legs of the U being forwardly positioned. A pair of upright support members are each pivotally mounted on each of the legs of the U-shaped member, proximate to the bottom portion of the U. A canopy is pivotally mounted between the upright support members on the upper end thereof, for shielding sunlight from the region between the legs of the U-shaped member. When the shade is employed in its ground supported embodiment, a pair of anchor spikes are pivotally mounted, one on each of the legs of the U-shaped member, as a forward ground support for the shade, the spikes being driven into the ground for anchorage. The bottom portion of the U for the U-shaped member serves as the rearward ground support for the shade. When the shade is employed in its chair-back support embodiment, a pair of clamps are used to clamp each of the legs of the U-shaped member to the frame of the back of a chair so that the canopy shades the back of the chair. A special clamping mechanism is employed to lock the pivotal mounting of the canopy to the upright support members, thereby making the canopy manually adjustable to follow the position of the sun.

Claims

1. A self-supporting sun shade, comprising:

a U-shaped support member having the bottom portion of the U as a rearward support for the shade and the legs of the U being forwardly positioned;

a pair of upright support members, one pivotally mounted on each of said legs of said U-shaped member, proximate to said bottom portion of the U;

a canopy pivotally mounted between said upright support members, on the upper ends thereof, for shielding sunlight from the region between said legs of said U-shaped member;

said pivotal mounting for said canopy to said upright support member, further comprising;

said upright support member being a hollow tubular structure;

a shaft rigidly mounted to said canopy and passing through a hole in the side of said upright support member;

a substantially U-shaped, resilient clamping member within said hollow tubular structure at the upper end thereof, having two legs, one on each side of said shaft;

a screw passing through the side of said upright support member and through a first one of said legs of said clamp and threadably engaging a second one of said legs of said clamp, for tightening said clamp about said shaft;

a cap sealably engaging said upper end of said hollow tubular structure for protecting said clamping member from environmental elements;

whereby said canopy can be locked into a fixed position with respect to said upright support member.

2. The sun shade of claim 1, wherein said canopy further comprises:

a storage compartment attached to the underside of said canopy.

3. The sun shade of claim 1, which further comprises:

a pair of anchor spikes, one pivotally mounted on each of said legs of said U-shaped member, as a forward ground support for the shade, driven into the ground for anchorage;

said bottom portion of the U for said U-shaped member serving as a rearward ground support for the shade;

said canopy further comprising a storage compartment attached to the underside of said canopy.

4. The sun shade of claim 1, which further comprises:

a pair of anchor spikes, one pivotally mounted on each of said legs of said U-shaped member, as a forward ground support for the shade, driven into the ground for anchorage;

said bottom portion of the U for said U-shaped member serving as a rearward ground support for the shade.

5. The sun shade of claim 4, which further comprises:

said canopy further comprising a storage compartment attached to the underside of said canopy.

6. The sun shade of claim 4, wherein said sun shade can be converted from a ground supported shade to a chair-back supported shade, by means of a pair of clamps, each clamping one of said legs of said U-shaped member to the frame of the back of said chair.

7. The sun shade of claim 1, which further comprises:

a pair of clamps, each clamping one of said legs of said U-shaped member to the frame of the back of a chair;

whereby said canopy shades the back of the chair.

8. The sun shade of claim 7, wherein said sun shade can be converted from a chair-back supported shade to a ground supported shade, by a pair of anchor spikes, one pivotally mounted on each of said legs of said U-shaped member, as a forward ground support for the shade, driven into the ground for anchorage, said bottom portion of the U for said U-shaped member serving as a rearward ground support for the shade.

9. The sun shade of claim 7, wherein said bottom portion of the U for said U-shaped member is removed, leaving said legs clamped to said chair frame.

10. The sun shade of claim 1, which further comprises:

a pair of clamps, each clamping one of said legs of said U-shaped member to the frame of the back of a chair;

said canopy further comprising a storage compartment attached to the underside of said canopy;

whereby said canopy shades the back of the chair.

11. The sun shade of claim 10, wherein said bottom portion of the U for said U-shaped member is removed, leaving said legs clamped to said chair frame.
