  • Patent number: 5382111
    Abstract: A children's play structure includes a hinged frame structure having mounted thereon a plurality of panels depicting murals or scenes. The hinged frame structure which is comprised of a plurality of hinging sections and which is of lightweight, simple and economical construction is provided with substantial rigidity by corner structures which include hinging apparatus at the upper and lower ends of vertical tubes to permit pivoting rotation of the corner structure relative to one but not the other of a pair of frame sections coupled thereby. Each of the upper and lower hinging apparatus includes a clevis and a lever releasably coupled to the horizontal tubes of the adjacent frame sections by plugs with resilient release tabs. The clevis and lever have interleaved legs which receive a shaft and an opposite cap within apertures therein to permit pivoting rotation between the lever and the clevis while at the same time providing substantial resistance to unwanted vertical flexure.

  • Patent number: 5362030
    Abstract: The present invention relates to a single post module which provides all the connections needed to make a fence. This module can be assembled, by unskilled persons, with other like modules to form fence posts by end-to-end assembly and connection. Each module in a post has a connector to which hollow fence rails or panel sleeves may be attached. Fence panels thus formed have a post at each end. Each module in every post has projecting hinge fins which, when overlapped with the fins of modules in similar posts, permits joining of up to four posts and their fence panels by making a pin connection at the common axis through the holes in the hinge fins at that location. This permits construction of a fence which can branch into as many as three new fences at any location.

  • Patent number: 5184800
    Abstract: A portable fence system including a snow fence panel having a wood frame of 2".times.6" posts bolted together at the corners, with a 4-foot wide strip of plastic snow fence material pulled taut across the center. Each panel is 8 feet long, with a height of 6'-8" or 8'-0", depending upon the application. In both cases the geometry of the frame is optimized for maximum snow trapping efficiency and maximum snow storage, and an opening at the bottom is optimized to eliminate the tendency for snow deposition at the fence. Panels are connected to one another by rebar pins passing through specially designed rotatably mounted U-clips, which also provide attachment to rebar anchors driven into the ground. The U-clip-and-pin connections allow rapid installation and take-down, and add flexibility needed for proper installation in irregular terrain. Panels can be overlapped at either the top or bottom as required to limit space between panels to 11/2", which improves trapping efficiency.

One or more sets of upper and lower ring-like fixtures and brackets with a pivoted element thereon may be provided at the opposite end of the panel to facilitate completion or extension of the pens. The pens are preferably constructed of upper and lower rails with horizontally spaced vertically arranged bars connected to the rails to form a rigid structure.

  • Patent number: 4174096
    Abstract: A fence is characterized by interchangeably mountable fence sections each having a front and a rear surface, and parallel pairs of vertical and horizontal edges. A mounting member having a mast-receiving opening therein is disposed adjacent each vertical edge of the wall portion of each of the fence sections. Each mounting member has a mating surface thereon disposed in the same plane as the mating surface provided on the other mounting member. When the first mating surface on the wall portion of a first fence section is matingly engaged with a mating surface provided on the other of the mounting members on a next-adjacent fence section, the mast-receiving openings therein are disposed in vertical registration. The fence section, including the wall portions and the mounting members, are integrally fabricated of a plastic material.

  • Patent number: 4072295
    Abstract: A baseball backstop or similar structure, such as dog run, fence section, etc., is constructed of panel sections uniquely connected together so the entire structure is foldable for shipment to the erection site. The panel sections are each made up of steel tubing, forming a frame, and of steel chain link fence fabric covering the frame. Adjoining frames are hingedly connected by sleeves of larger diameter steel tubing rigidly secured to the frame of one of the adjoining panel sections, as by welding, and closely but freely encircling a frame member of the other of the adjoining panel section. The chain link fence fabric of the one panel section is secured at one of its sides to the frame of that section and at its opposite side to the said frame member of the other section. Set screws in the sleeves provide rigidity for the structure after erection.
