Abstract: A light weight and collapsible platform and platform support structure usable as the deck and central structure of a folding boat and of a levelable, raised platform tent camper. This collapsible platform support structure is a unique arrangmeent of compression carrying arms radiating out from a central hub and jacking device, with an arrangement of tension carrying cables linking and supporting the radial arms into a rigid geometry. By concept and design the structure maximizes horizontal platform area for a minimum of weight and structure. Light weight allows transportability and collaspsibility allows stowability. The structure is opened from a collapsed state to a rigid erected state by operation of the jack, which moves the cable hub away from the arm hub. This action rotates the arms downward, loading the arms in compression and the cables and platform in tension, eventually locking the the structure into it's rigid erected geometry.

Abstract: An automatic sprinkler head comprising a body with a passageway for fire-extinguishing fluid, a frame extending from the body having a deflector plate opposite the passageway, a closure assembly (including a closure thimble) for closing the passageway, a thermally responsive glass bulb interposed between the closure assembly and the deflector plate, and a means to minimize lodgement of the closure assembly. The means to minimize lodgement of the closure assembly is interposed between the glass bulb and the closure thimble. The means to minimize lodgement is preferably an underground spiral spring and causes the closure assembly and any glass bulb fragments to tumble away from the axis of the passageway when the glass bulb fractures, thus minimizing the possibility of the closure assembly and glass bulb fragments becoming lodged against the deflector plate.
