Abstract: A clip for coupling a first wall panel comprising a first joiner and a core adjacent to the first joiner and a second wall panel comprising a second joiner includes a longitudinal wall, a vertical wall perpendicular coupled to the longitudinal wall, a recessed wall coupled to the vertical wall and a retaining wall coupled to the recessed wall extending from the recessed wall. The vertical wall, the recessed wall and said retaining wall extend into a channel formed by the second joiner. An insert wall extends from the longitudinal wall and is sized to be received outside the first channel.

Abstract: A wall panel includes a first and second planar skins and a core disposed therebetween. A first and second lateral edge extends between the skins. The second lateral edge comprises a female receiver. The first lateral edge comprises a male extension extending therefrom. The female receiver is formed in the core and has a depth equal to or greater than a length of the male extension. The male extension is formed from the core comprises a first parallel surface extending parallel to and offset from the first planar skin and a second parallel surface extending parallel to and offset from the second planar skin. A first tapered portion comprises a first tapered surface extending at an angle relative to a longitudinal axis from the first parallel surface to a rounded end, and a second tapered surface extending at the angle from the second parallel surface to the rounded end.

Abstract: An exemplary exercise device includes, among other things, an attachment structure configured to be mounted to a support assembly, a first arm directly pivotably connected to the attachment structure, a second arm directly pivotably connected to the attachment structure, a bracket directly pivotably connected to the first arm and directly pivotably connected to the second arm, and a catch member configured for accepting a weight bar. The catch member is pivotably connected to at least one of the first arm, the second arm, or the at least one bracket such that the at least one catch member is pivotable relative to the at least one bracket.

Abstract: An example resistive pull exercise device includes a support housing having a first passageway and an opposing, second passageway, and a tension member to selectively impart a resistive force to a length of material spanning the first and second passageways.

Abstract: An Emergency Isolation and Treatment Shelter (EITS) rigid wall system is modular and includes two support columns and a rigid wall assembly therebetween. Each support column is a tubular generally rectilinear member in cross-section having a center opening and a wall receipt slot on each side thereof. Intermediate each wall receipt slot is an auxiliary area which permits running of conduits for electrical wiring, plumbing conduits as well as junction boxes, switch boxes or the like.

Abstract: A weightlifting system includes a weight arm system which may include various arm systems such as an incline arm system or a decline arm system. The weight arm system includes a weight arm mounted to a bracket assembly through an omni directional pivot system to permit the weight arm to pivot about a first axis and a second axis. The first axis is defined along the length of the bracket assembly while the second axis is transverse thereto. The combination of the movement about the first and second axis relative the bracket assembly permits the novel omni directional movement.

Abstract: A weightlifting system includes a weight arm system having a handle which may be mounted in one of a multitude of clocked positions. A handle engagement member extends radially from the handle adjacent the end section and includes a multitude of radially extending engagement male members to take the shape of a gear or multi-pointed star. The multitude of radially extending engagement members of the handle engagement member corresponds with a multitude of radially extending engagement members which defines an arm engagement member on the weight arm about an opening.

Abstract: A stage system and apparatus for construction of flat stages, choral risers, and the like which utilizes a basic structural flat rectangular panel module with an edge of extruded material having a re-entrant groove on the outer surface and upper and lower sockets on each side of each corner of the panel to receive support legs fashioned to be received in the bottom sockets. Railing stanchions are provided to seat in the top sockets. In the vertically spaced and overlapping choral risers, the top sockets serve to locate the overlap and mechanically lock the panels in an overlap position. Inserts received in the re-entrant groove interengage with the re-entrant groove of an adjacent panel to provide lateral and vertical stability to adjacent panels.Special leg brackets are provided to engage the bottom sockets of two to four adjacent module panels to provide vertical support and lateral retention. Leg assemblies can be formed as a folding frame to facilitate shipping and storage.
