Abstract: Sports equipment include a frame with an outer telescoping member including a row of a plurality of openings along its length and a rotation-limiting slot at a first end. An inner telescoping member includes a push button that engages one of the plurality of openings of the outer telescoping member to secure the inner telescoping member to the outer telescoping member. A stub includes a pin that engages the rotation-limiting slot of the outer telescoping member to limit rotation of the outer telescoping member relative to the inner telescoping member. The outer telescoping member may rotate relative to the stub and the inner telescoping member to change a length of at least one member of the sports equipment frame.

Abstract: One embodiment provides a foldable throwback device comprising a front frame, a base frame, and telescoping angle members. The front frame is adapted to secure a bounce-back surface and is foldable into at least three sections without removal of the bounce-back surface. The base frame is coupled to the front frame by hinge brackets that allow the base frame to fold substantially flat onto the front frame without significant disassembly. Each telescoping angle member extends from the base frame to the front frame, and is adjustable to allow angling the front frame relative to the base frame. Each telescoping angle member may include a rotation-limiting mechanism and a safety mechanism that prevents unintentional detachment.

Abstract: A fastening mechanism for temporary structures with a frame with one or more attachment points disposed therein, a rope, a cover configured with one or more sleeves through which the rope may be inserted, one or more fasteners for securing the rope to the attachment points, and a pass-through loop pre-configured in the rope, such that a further loop can be formed by passing a section of the rope through the pass-through loop.
