  • Patent number: 5987707
    Abstract: A cord retaining device consisting of a T-shaped housing with three legs. Through holes extend through each leg with two of the holes in two legs being aligned with each other. The third or other leg's through hole intersects with the two aligned holes. At the third leg there are two opposite cord retaining grooves that open upwardly and taper downwardly. A bottom slot extends along the length of the two aligned legs and has an enlarged mid portion. By placing a cord having a diameter slightly greater than the diameter of the two aligned housing through holes, such as a bungee cord, through the bottom slot and pulling a mid portion of the cord into the third leg, a loop may be formed by the pulled portion. Lower portions of this formed loop may be inserted into the cord retaining grooves to fix the cord therein. A second bungee cord may also be used with the first bungee cord and housing.

  • Patent number: 5511290
    Abstract: The elastic cord tensioning and length adjusting apparatus is designed to allow the user to have much more flexibility with a single length elastic cord, rather than using a number of cords of different lengths. The apparatus can adjust, both the tension and length of elastic cords, by allowing the user to loop different lengths of the cord in a mechanism that can lock the looped section of elastic cord so that the length of the cord not in the loop is shortened and the tension is increased. The apparatus comprises a main horizontal body having two apertures designed for the cord to pass through. A locking mechanism fits into a center aperture in the main horizontal body and has two end notches to allow the elastic cord to fit into those notches. A spring tensioning device and a retaining piece maintain the lock in position.

  • Patent number: 5255866
    Abstract: A stair relief device is positioned around connecting plugs, splice or the like to relieve the contained plugs, splice or the like from any tension which is in the cord. It consists of a rigid hollow cylinder having two rigid circular flanges, extending outwardly at opposite ends of the cylinder. Each of these flanges has positioned therein two slots of appropriate size and shape to permit an electrical cord to pass through the slot. On each flange the two slots are positioned one hundred and eighty degrees (180.degree.) around the flange from each other. The slots in each flange are aligned directly opposite the slots in the other flange. The section of the cord to be protected is positioned within the cylindrical portion of the device. The cord at either end of the device is then positioned back through the slots in the flanges and turned at least one hundred and eighty degrees (180.degree.

  • Patent number: 5226216
    Abstract: A clamp assembly with a releasable bail for securing and suspending cables, drop wires or the like that utilizes a locking structure cooperating with an aperture in a tail of the clamp assembly to secure and lock the releasable free end of the bail to the clamp assembly. Preferably, the locking structure is a foot segment and head at the end of a leg of the bail with a reduced portion permitting passage of the foot segment from an entry portion along a connecting portion to locate the head at a lock portion. Additionally, the other leg of the bail can be slideably attached utilizing an interlocking structure that reduces bail deformations during installation. Furthermore, the present invention provides a method for assembling the cable clamp assembly wherein the first and second legs are assembled and attached to the tail, and also providing a method for simultaneously forming the reduced portion of the second leg and a deformed region in the tail to capture the first leg in the tail.

    Abstract: A rope-tying device is disclosed which facilitates convenient and efficient formation of a loop in the free end portion of a rope. Economical fabrication and efficient use of the device is facilitated by its configuration as a unitary, generally cylindrical tubular body formed from a single piece of material. The tubular defines a pair of diametrically opposed, longitudinally extending slots, with the body including a pair of annular end body portions, and a pair of diametrically opposed side body portions extending between the end body portions. For loop-formation, the free end portion of a rope is inserted through the device, and a half-loop displaced laterally through one of the slots. The free end of the rope is thereafter inserted through the half-loop, with tension exerted to complete loop-formation.

  • Patent number: 4769874
    Abstract: The line retension device includes a relatively thin plate having means defining an elongated passageway for receiving the line in a friction tight manner. The cross-sectional area of at least a portion of the passageway is complementary shaped and sized relative to the cross-sectional shape and size of the line. In one form of the invention, the passageway extends in a tortuous or non-linear configuration in the unstressed condition of the plate to grip the line frictionally. The plate is adapted to be flexed manually to deform it to a position where the configuration of the passageway is closer to that of a straight line, thereby permitting the line and the plate to be moved relative to one another in a much more facile manner.

  • Patent number: 4506417
    Abstract: A fastener for securing in position a string to be used for gathering the skirt of a coat or the open edge of a pouch, for example, is constructed of a housing provided therein with a blind cavity, a sliding member admitted into the blind cavity of the housing, and a spring interposed between the housing and the sliding member; the housing and the sliding member being respectively provided laterally therein with perforations and insertion holes adapted to come into mutual coincidence when the sliding member is pushed into the housing against the energizing force of the spring. Since opposed end portions of a given string can be inserted sidewise through the coinciding insertion holes into the perforations, this string fastener can be used advantageously without requiring the opposed end portions of the string to be always kept in mutual contact. It imposes no limitation upon the length of the string to be tied and enjoys ease of handling.
