SUMMARY OF THE INVENTION
Considered broadly, tents according to the invention are of the umbrella type and comprise a collapsible frame including a plurality of legs pivoted at their upper ends to an upper clevis member. At points spaced downwardly from their upper ends, each leg has pivoted thereto a radial stay member extending inwardly of the tent to be pivoted to a lower clevis. The upper clevis includes a central downwardly opening recess. The lower clevis has fixed thereto an upwardly projecting post or rod adapted to engage the upper clevis so as to stop upward movement of the lower clevis. Each leg comprises an elongated lower section which can be relatively stiff and the upper end of the lower section is pivoted to an upper section which is relatively flexible and resilient so that the upper portions of the legs conform to the dome of the sheet material forming the tent cover. The sheet material advantageously can include a complete or partial floor portion and the lower ends of the legs of the frame engage the floor when the tent is erected. Advantageously, the legs and stays of the frame are of extruded polymeric tubing. The clevis members are molded from polymeric material, as are all of the pivotal connector members of the frame.In the drawings, which form a part of this specification,
