  • Publication number: 20240092054
    Abstract: A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

  • Patent number: 9121222
    Abstract: A gate bracket is formed of a planar web in which two rectangular portions along two edges of the web are bent to define a first pair of perpendicular flanges, and two other rectangular portions are bent from an inner portion of the web to form a second pair of perpendicular flanges. The flanges of the first pair are spaced from the flanges of the second pair by a distance corresponding to the dimensions of the structural members used to construct the gate. The invention provides a rigid bracket of simpler and lighter construction than prior art brackets.

  • Patent number: 7494095
    Abstract: A hanger for mounting a gutter to a structure with a fastener. The hanger may include a bracket arm having first and second ends and extend widthwise to the gutter. A raised fastener guide portion may be connected to the first end of the bracket for delivery of the fastener. An outside gutter engagement device connected to the second end of the bracket arm for engaging the outside wall of the gutter and an inside gutter engagement device connected to the fastener guide portion for engaging the inside wall of the gutter and for receiving the fastener to mount the gutter to the structure may also be provided. A support arm may also be provided having first and second ends. The first end may be connected to the raised fastener guide portion and the second end of the support arm may abut the inside wall of the gutter when the hanger is attached to the gutter.
