Abstract: A trampoline is disclosed that includes first, second, and third frame members, a pole member, and a sleeve joint coupling. The sleeve joint coupling includes a first arm with a first passage, a second arm with a second passage, a third arm extending away from the second arm and including a third passage, and an aperture. The first passage has a first axis, and the second and third passages shares a substantially common axis. The first axis is substantially perpendicular to the substantially common axis. The first frame member is received in the first passage, the second frame member is received in the second passage, the third frame member is received in the third passage, and the pole member is received in the aperture to extend away from the first frame member. At least one of the second and third arms defines an uppermost surface of the sleeve joint coupling.

Abstract: A portable shelter includes a frame assembly and a canopy that is supported by the frame assembly. The canopy includes a transparent skylight.

Abstract: A portable shelter has a canopy assembly that includes a main portion and an awning. The shelter also includes a frame assembly with a main frame and an awning support member. The main frame defines a main area and supports the main portion of the canopy assembly such that the main portion covers the main area. The awning support member includes a first portion operably coupled to the main frame and a second portion that extends away from the main area. The awning support member is resiliently flexible, and the awning support member supports the awning such that the awning covers an adjacent area that is adjacent the main area.

Abstract: A support structure for use primarily as a lightweight, portable, strong, and fracture resistant tent support and the like, and method for making thereof. The support structure includes a fiberglass core and a resilient outer layer of material that is at least 0.2 millimeters thick. Preferably, the outer layer is made of polyethylene that is between 0.5 to 0.6 millimeters thick, inclusive. In a preferred embodiment, the support structure is curved to conform with the shape of the tent it supports, thereby preventing the support structure from springing back when inadvertently released from the tent. More preferably, the support member includes a plurality of elongate curved sections that are detachably secured together to form the support member.
