COLLAPSIBLE TENT AND FRAME THEREFOR

This invention provides an improved collapsible tent and tent frame, more particularly of the type commonly called an umbrella tent.

BACKGROUND OF THE INVENTION

Umbrella tents have long been known and widely used. Collapsible umbrella tents of various types go back at least to the turn of this century and have usually included a collapsible frame on which the fabric or other flexible sheet material of the tent is supported when the tent has been erected. The term "umbrella tent" is commonly used in the trade because the frames for such tents can be erected and collapsed in much the same manner as an umbrella. Typical tents of this type are shown, for example, in the following United States of America patents:

1,079,757 Gould
1,124,420 Gough
1,666,757 Snyder
3,000,386 Shulze et al
3,794,054 Watts
4,033,366 Forget

Though such tents have achieved considerable popularity and commercial success, there has been a continuing need for improvement.
