Abstract: A removable chin-up bar arrangement includes spaced body members situated at opposite ends of a chin-up bar extending therebetween, the bar being rotatable with respect to the body members. Opposed pincher members are swingably attached to each of the body members and are adapted to extend about and hang the body members and the chin-up bar from and overhead support, such as the framing extending about an interior doorway. A gear tooth lock mechanism extending between the ends of the chin-up bar and each of the pincher members, the lock mechanism moving the pincher members in unison toward each other and causing the chin-up bar to rotate in a first direction and upon rotation of the bar in the opposite direction causes the pincher members to open from each other, permitting removal of the chin-up bar arrangement from the doorway.

Abstract: A tent is provided for selective attachment to a conventional trampoline. The tent includes a low profile domed shell having a base that is removably secured around the perimeter of the trampoline. A pair of primary support rods are hingedly mounted on opposing sides of the trampoline and are biased against the shell to keep the shell elevated off of the trampoline. An adjustable support rod has opposing ends slidably mounted to opposing ends of one of the primary support rods. By disconnecting the shell from the trampoline along one side of the trampoline, the shell and support rods can be folded about the opposing side of the trampoline. An apron is attached to the shell along the opposing side of the trampoline and is configured to enclose the shell and support rods below the top of the trampoline. Ties are then used to secure the apron around the shell which is connected to the trampoline frame.
