Abstract: A collapsible shelter/tent, such as for example an umbrella tent, has a collapsible frame with a plurality of legs that are erected by manually moving two devises toward one another. The shelter/tent includes an improved locking mechanism that very securely maintains the structure in an erected position. The improved locking mechanism includes a generally vertical pin extending from one of the devises that is received inside a socket supported on the other of said clevises. The socket has an engaging member therein that can engage a groove in the generally vertical pin after said generally vertical pin has been inserted into said socket. Preferably, the engaging member is spring biased into the groove. The shelter/tent also includes a variety of novel frame structures. An erection device for erecting a collapsible tent is also included. The erection device includes an elongated pole and a slide member that can be used to control relative movement of the devises toward and away from one another.

Abstract: The present invention is directed to a modified clevis assembly for collapsible tents. The clevis assembly is modified so that it contains a conical pin entry guide on a first clevis member to allow safe directing of the tip of the pin on a second clevis member into the recess of the first clevis member. In the modified clevis assembly the pin is guided into the recess should any torque or twist to the frame occur when the tent is erected due to the inherent flexibility of the materials used in the construction of tent frames and the tendency for the user to inadvertently apply force off of vertical through pressure from the user's hands when moving the lower clevis member toward the upper clevis member. The conical pin entry guide preferably forms an integral part of the under surface of the upper clevis member or of the upper surface of the lower clevis member. The clevis assembly is further optionally modified to include in or on the upper clevis member means to receive a fly adaptor assembly.

Abstract: The invention provides an improved collapsible tent and tent frame of the umbrella type. The frame includes a plurality of legs pivoted, at the upper ends of the legs, to an upper clevis member. Each leg has pivoted thereto a radial stay member spaced downwardly from the upper end of the leg. The stay member extends inwardly of the tent to be pivoted to the lower clevis. The upper clevis includes a central downwardly opening recess and the lower clevis has fixed thereto an upperwardly projecting post or rod which is adapted to engage the upper clevis so as to stop movement of the lower clevis. Each leg comprises an elongated lower section which can be relatively stiff. The upper end of the lower section is pivoted to an upper section which is relatively flexible and resilient so that the upper portion of the legs can conform to the dome of the sheet material forming the tent cover or ceiling.
