  • Patent number: 4307861
    Abstract: A lightweight, collapsible frame for holding a plastic trash bag upright to receive trash. The frame includes a triangular base formed from three pivoted strips that can be folded together for storage when not in use. Additionally, the frame includes three tubular posts or props which are removably attachable to the corners of the triangular base in such a way as to stand upright around the space above the base. Each of the tubular posts has a crosspiece fitted to its upper end for pivotal movement between a first position crosswise of the post, where it serves to prop up the wall of a trash bag in the space above the base when the top of the bag is folded down over it, and a second position at right angles to the first for easy packing and storage purposes. A spring clip is fastened to each of the tubular posts near its upper end.

  • Patent number: 4203416
    Abstract: A device for holding a pot on a gas range burner in a moving recreational vehicle. The device is attachable to a burner grate of the type having radial bars with sloping lower edges, and it has a deck with lateral edges that interfit with a neighboring pair of the radial bars so as to support the deck on the bars and permit it to span the space between them. A pair of locking levers are pivotally supported at a common point under the deck. From their common pivot point, the locking levers extend forwardly and terminate in outturned, downwardly offset feet designed to swing outwardly into frictional contact with the lower edges of the neighboring radial bars from points intermediate the bars. To the rear, the locking levers are formed into a pair of handles. Mounted above the deck on a pair of pivoted brackets are two clamping members with forward portions formed into curved arms for embracing the pot, and rear portions serving as handles.
