  • Patent number: 6467742
    Abstract: A poster gripping extrusion device for the close-in maintenance and rigid support of a flexible sheet of display material. The device includes an elongated planar base having a first or distal edge and a proximal or second edge defining a width of said base. A leg extends parallel to the base, the leg having a distal edge and a proximal edge, and only a single web or bridging portion extending between the second edge and the proximal edge of the leg to provide compactness to the device. A pivotable clamp extends from the distal edge of the leg, the clamp providing a first and a second line of contact between the clamp and the base to securely hold a sheet of material therebetween. The clamp has a distalmost edge which extends beyond the distalmost edge of the base portion of the device, to permit ease of manipulation of the device in “close-in” locations.

  • Patent number: 5718402
    Abstract: The present invention comprises an elongated extruded plastic clip having a planar base portion joined to a planar leg in a parallel spaced apart manner. The leg and base are connected by a bridging portion. The leg has an elongated distal edge to which a curved clamp is attached. The clamp is secured to the leg by a flexible hinge. The clamp extends beyond the distal edge of the base to permit easy manual opening of the clamp and articulation thereof with respect to the base.
