Abstract
A plastic sheet support clip is provided for use in conjunction with a plastic sheet which performs the function of a protective seal to inhibit the passage of water into the cargo compartment of trucks having a door that is not adequate for water protection. This plastic sheet support clip is formed from a single thin piece of sheet metal. When the metal is stamped the invention is formed comprising a channel form retainer open at the top and a mounting flange having holes to assist in securing the invention to the side walls of the truck. The retainer has a bottom, a front wall and two side walls. A V-shaped notch is formed in the front wall and opening at the upper edge of the front wall. Lower portions of the notch are sharpened and act as a plastic sheet tearer or cutter.
Claims8
A plastic sheet support clip comprising an open-topped, channel-form retainer and a mounting flange that is connected with said retainer in structurally rigid relationship, said channel-form retainer having a relatively thin front wall provided with a V-shaped notch opening at the top of the retainer for receiving a gathered-together marginal edge portion of a plastic sheet therein and initially retaining such plastic sheet in suspended relationship, said notch having the side edges thereof inwardly convergent toward the lower closed end to sufficiently decrease the spacing therebetween so as to enable the side edges to perform severing of a plastic sheet when such sheet is pulled toward the notch's vertex by a force substantially greater than the suspended weight of such plastic sheet.
