This invention relates to a portable shelter or tent enclosure having a self supporting frame structure that may be pivotally erected and collapsed for supporting a fabric cover. The frame comprises at least three substantially U-shaped frame members which are linked at the ends of each of the parallel side arms remote the top of the U at about a common point. At least two of the three frame members are braceable in an angularly spaced apart position by segments comprising a pair of laterally braced parallelograms pivotally linked to the pairs of side arms. The frame structure has a removably securable horizontal frame brace that is easily connected to and removed from the top of the laterally braced parallelogram of the frame and includes arms extending angularly downwardly to the side from the brace to the parallel side arms forming the base of the laterally braced parallelogram thereby providing an effective lateral brace to the frame.

A portable shelter or tent enclosure comprising a pivotally collapsable self-supporting frame for supporting a fabric cover comprising a pivotally collapsable self-supporting frame having at least three substantially U-shaped frame members, each substantially U-shaped frame member having a pair of parallel side arms spaced from each other at the same end by a top arm, the three pairs of parallel side arms each at the end remote the top arm linked to about a common point, at least two of the three pairs of parallel side arms each at the end remote the top arm pivotally linked to the about common point sufficient to permit at least two of the three substantially U-shaped frame members to be pivotally spaceable so as to permit the three substantially U-shaped frame members to be angularly spaced apart one from the other, at least two of the three substantially U-shaped frame members braceable when angularly spaced one from the other by a pair of releasable locking means each one comprising a horizontal locking segment pivotally attached at one end to an intermediate point along one side arm, a second locking segment pivotally attached at one end to an intermediate point along a sidearm angularly spaceable from the other side arm, each of the two locking segments at the end opposite that which is linked to the side arms pivotally linked one to the other, the horizontal locking segment and second locking segment braceable in an angularly spaced position so as to form a parallelogram laterally braced when the frame is erected by a diagonal locking segment extending angularly downwardly between the horizontal locking segment and the second locking segment, the diagonal locking segment composed of two subsegments each one attached pivotally at one end to one locking segment and at the other end pivotally connected one to the other, and; the pair of parallel side arms of each of at least two of the three frame members laterally braced apart by a removably securable horizontal frame member extending between each horizontal locking segment of the pair of releasable locking means, the removably securable horizontal frame member carrying two lateral support arms each one connected at one end to an intermediate point along the removably securable horizontal frame member and extending angularly downwardly to the side each one to surmount at the opposite end one of the two side arms of a substantially U-shaped frame member.
