Abstract:
1. A one-piece holder for clamping a flexible sheet material, comprising: an extruded plastic, elongated channel member produced in a single extrusion of a single plastic material having a uniform durometer throughout, comprising a generally rectilinear base wall, a forward leg, a rearward leg, and a top wall each having two opposite ends, formed in situ; wherein said rearward leg and said forward leg also are generally rectilinear and are disposed generally perpendicular to said base wall with one of said ends of said rearward leg being connected to one of said ends of said base wall and one of said ends of said forward leg being connected to the opposite one of said ends of said base wall, and said other end of said forward leg defining a free end, wherein said forward leg is short relative to said rearward leg and has an inner face forming a bearing surface, and wherein one of said ends of said top wall is connected to the other of said ends of said rearward leg and the other of said ends of said top wall defines a free end, and wherein said top wall slopes downwardly from said rearward leg towards said front leg and extends down from said rearward leg to a position lying inside said forward leg and below said free end of said forward leg so that it is urged towards the inner face of the forward leg, so that its free end biasedly and resiliently engages the bearing surface of said inner face of said forward leg, thereby eliminating the necessity of further manipulation of the legs after extrusion to orient them in their proper gripping position.
