  • Patent number: 9353892
    Abstract: A cable retaining apparatus is disclosed. The apparatus includes a band that is wrapped around a group of cables and a clamping portion that holds the ends of the band. The clamping portion has a body portion that is fixed to one end of the band. The body portion also has an axle mounted to it, the axle having a slot cut into it to receive the other end of the band. The end of the axle has a rotatable head for engagement by a tool such as a spanner so that rotation of the head causes the axle to rotate. The body portion also has an aperture that is aligned with an aperture in the axle so that a pin can extend through the apertures to prevent rotation of the axle. In use the band is placed round the cables and its end inserted into the slot. The axle is then rotated and band winds around the axle until it tightens around the cable. The pin is then inserted into the apertures to prevent the band unwinding.

  • Patent number: 8894000
    Abstract: A cord winder device that may be used to shorten the length of a pull cord that hangs from a window covering, such that it can adjust the exposed length of window blinds. The cord winder device includes a spindle and sides that overlap the spindle. A cord hanging from the window covering may be wound around the spindle so that the length of the cord is reduced. Reducing the height of the cord may keep the cord out of reach of children and prevent injury. The sides of the spindle may have slots to secure the cord to the cord winder device after it is wound around the spindle.

  • Patent number: 8544784
    Abstract: A line tightening device with a detachable handle, a hook and a coupler for securing the handle and the hook together while the tightener is being used. After the line tightener is used to achieve the desired tension in the line tightened, the handle and coupler can be quickly and easily disengaged and removed from the hook, thereby leaving only the hook attached to the tightened line. The hook is adapted for tightening the line by forming and fixing convolutions about its shank. A tether secures the hook to adjacent portions of the line to prevent accidental separation of the hook from the tensioned line.

  • Patent number: 7878342
    Abstract: A clothesline system comprises at least two separate cables that are independently tensionable through separate cable tensioning devices. The tension devices are attached together to provide for common, parallel movement of the separate cables though the cables are separately passed around separate pulleys at the both ends of the system. The two separate cables add strength to the system. The separate cables are preferably wound in left and right windings to prevent unraveling of the braid of the cable. By providing separate cables, assembly of the system is less complex as the two loops of cable are separate.

    Abstract: A method and a spool (1, 10, 21, 22, 35) for shortening the length of a cord (14) and optionally tensioning it at the same time is provided. The spool has a shank having two ends each of which has a transverse retainer formation (4, 13, 20, 40, 51 and 5, 11, 25, 33, 36, 42, 49, 50, 58) adapted operatively to prevent unravelling off the shank of cord wound around the elongate shank, at least whilst it is held under tension and with the axis of the shank extending in the same general direction as that in which the cord extends. A keeper formation (4, 13, 20, 40, 51) that is preferably one in the same with the ring and a formation at one end of the shank cooperates with a cord to maintain said end in association with the cord whilst the shank is rotated to wind cord onto the shank by rotation thereof.

  • Patent number: 7252259
    Abstract: A method of drawing lines into a housing includes: rotating a dial in a first rotational direction of the dial such that a first spool located in an interior of the housing is mechanically rotated in a first rotational direction thereby winding a first line thereabout; and rotating the same dial in a second rotational direction opposite to the first rotational direction such that a second spool located in the interior of the housing is mechanically rotated in a first rotational direction thereby winding a second line thereabout. The rotating of the same dial in the second, opposite rotational direction does not result in unwinding of the first line from the first spool, and the rotating of the same dial in the first rotational direction does not result in unwinding of the second line from the second spool.

    Abstract: A tool for tightening a plurality of wire lengths that extend between a first bracing location on a first fence support and a second bracing location on a second fence support, the wire lengths defining an axis extending generally parallel to their lengths. The tool includes a body adapted to be transversely inserted between the wire lengths so that the wire lengths pass around the body. The body has at least one seating portion formed on its outer surface for retaining at least one of the wire lengths generally between the ends of the body when the body is inserted between the wire lengths. The body is adapted so that, when inserted between the wire lengths, the body can be selectively rotated about the axis to twist the wire lengths around one another and thereby exert a contracting force on the fence supports.

  • Patent number: 6341742
    Abstract: A line tightening device, for use in removing slack from a flexible line has a plate-like body member. The body member has a pair of spaced holes and a pair of opposing ends. The holes are between the ends of the member. One end is bent generally at a right angle to the body member. At least one line receiving groove is provided along an edge of the bent up region. A flexible rope or line is strung through the pair of holes. The rotation of the body member in a first direction, around an axis substantially perpendicular to said first plane winds the flexible line around itself along an axis substantially midway between said two holes. This is repeated until the flexible line is taut. Then the flexible line is locked into one of the line receiving grooves. The line receiving groove is on the side of the body member that faces away from said direction of rotation, such that the device cannot unwind.

  • Publication number: 20010015392
    Abstract: A reel which is driven by a motor is disposed in a casing. First and second restraining mechanisms for restraining movement of a cable are located at first and second openings formed in the casing for insertion of the cable. The cable extends between said first and second openings and is wound around the reel. One end of the cable is secured by the first restraining mechanism, and the motor is activated to rotate the reel, thereby winding the cable around the reel. When a pressure sensor located on the surface of the reel detects that the pressure between the cable and the reel reaches a given value, the motor is stopped. The other end of the cable is secured by the second restraining mechanism.
