  • Patent number: 9062456
    Abstract: In a load-bearing construction (1) having at least one load-bearing element (2), the load-bearing element (2) has at least one cavity (5) in which at least one rod (4) is disposed, the total cross-sectional area of all rods (4) each arranged in a cavity (5) being smaller than the cross-sectional area of this cavity (5), and the remaining volume of the cavity (5) being filled with a material (6). The rod (4) is displaceable along its length relative to the load-bearing element (2) when the load-bearing element (2) is deformed, the rod (4) being non-displaceably fixed at only one point relative to the load-bearing element (2) and being designed such that it dissipates energy upon the occurrence of a relative displacement with respect to the load-bearing element (2).

  • Patent number: 6113076
    Abstract: A sheet of plastic used with a perimeter structure (e.g., fence) to prevent certain animals from climbing up the fence. The sheet of plastic is characterized by a smooth, slippery surface so that animals are unable to obtain a foothold on the sheet. Apertures may be preformed in the plastic sheet for permitting a fastener to be coupled to the sheet to enable the sheet to be mounted to the outside surface of the perimeter fence. Backing strips having preattached fasteners may be placed on the inside surface of the fence to facilitate attachment of the plastic sheet on the outside surface and to permit some degree of natural movement thereof after installation. The plastic sheet preferably comprises polyethylene having a thickness between about 0.050-0.060 inches.

  • Patent number: 5975789
    Abstract: A plastic clip, a plurality of which are employed to attach a plastic or fabric material to wire frame garden structures and wire fences, is formed in the general shape of a cylindrical shell, open at one end and closed at the other end, a peripheral wall of the shell having a pair of diametrically opposed slots formed longitudinally therein, each of the slots being tapered and terminating at an interior end thereof in a circular notch portion having a diameter slightly larger than the width of the tapered slot at its narrowest point. Each plastic clip may be quickly snapped into place over the plastic or fabric material and onto a wire member of the wire frame structure or wire fence. At such time as it is desired to remove the installed plastic or fabric material, each of the plastic clips holding it in place may be quickly and easily unsnapped from the wire member to which it was previously attached.

  • Patent number: 5836572
    Abstract: Artificial stones (10) are molded in a predetermined number of different shapes and a substrate (20) is expansion-molded from foam plastics. Artificial stone receiving recesses (22) are molded integrally with the substrate (20) so as to be paired with the respective artificial stones (10). The artificial stones (10) are adhesively inserted into the corresponding receiving recesses (22) so that such insertion may serve to provisionally prevent the artificial stones (10) from scaling off or falling off before setting of adhesive agent. A protruding rib (21) bordering and defining the respective artificial stone receiving recesses (22) serves also as a joint base adapted to support the overlying joint mortary (23).

  • Patent number: 3950803
    Abstract: A boat stanchion is formed of a single, continuous strand of fiberglass and thermosetting resin. The fiberglass strand is wound into a loop having a multiplicity of turns and the loop is then flattened to form a substantially straight bundle of overlapping strand sections. The strand bundle is placed in a mold with thermosetting resin. One half of the mold includes a pair of pointed rods which separate the strand sections when the two mold halfs are brought together to form two holes. The partial loop of overlapping strand sections at one end of the bundle encompasses one of the holes and approximately one half of the overlapping strand sections at approximately a mid-point of the bundle are positioned on one side of the other hole and the remainder thereof are positioned on the other side of that hole.
