  • Patent number: 4821543
    Abstract: The present invention provides a double ended key ring that includes a pair of key holders for retaining a set of keys. The key holders are movably connected to a central housing and are biased to retract into a pair of seats located at the ends of the housing to prevent the removal of the keys from the key holders. When the key holders are pulled away from the housing, the keys may then be removed from the key holders.The biasing mechanism for the key holders is located entirely within the housing. To this end the housing includes a central passageway that has a narrow bore, at one end, to preferably slidably receive a spring loaded lock pin that projects through the bore and is connected to one of the key holders. In order to permit the spring loaded lock pin and key holder to be assembled, the other end of the bore remains open until closed by a bushing. The bushing includes a tubular sidewall and an endwall having another narrow bore.

  • Patent number: 4754531
    Abstract: An elastic tie down comprises an elastic tube that carries a slack rope inside thereof. The tube is tightly crimped directly to the rope, so that pulling the rope ends stretches the tube and imparts elastic qualities to the tie down. In a modified embodiment, an annular insert is placed into the ends of the tube, and the rope passes through the insert. The tube and insert are clamped, causing the insert to collapse to grip the rope. The present invention also includes abutments crimped to the rope for cooperating with bushings placed within the tube ends. The bushings are split and have inwardly converging surfaces that terminate in grooves. Tension applied to the rope ends causes the abutments to contact the bushing converging surfaces and force the bushings apart and into a tight grip with the tube and with solid rings surrounding the tube over the respective bushings. The invention further includes split sleeves held in place in the tubing ends with wedges. A passage through the sleeves receives the rope.

  • Patent number: 4694541
    Abstract: An elastic tie-down comprises as inelastic rope having enlargements thereon that are captured by an elastic sleeve. The elastic sleeve is shorter than the spacing between the rope enlargements. Pulling the rope ends causes the rope enlargements to bear against the sleeve ends and stretch the sleeve. The rope ends are provided with hooks. The length between the hooks is adjustable without affecting the elastic properties of the tie-down by a clip that slidably receives the standing end of one of the rope ends extending from the sleeve. The clip also secures the rope end, thereby creating an adjustable sized loop in the rope. A hook is slidably received over the rope in the loop. Sliding the clip along the rope standing end varies the size of the loop and thereby alters the length between the two hooks independently of the tension in the elastic sleeve.

  • Patent number: 4279062
    Abstract: A snap shackle has a body formed on one side with an attachment such as a swivel eye and on the other side with a C-shaped arm having an outer end forming a pivot for a complementarily shaped pivotal arm whose free end in turn is engageable against the shackle body to form another eye. A latch constituted as a stirrup pivotal about an axis parallel to the pivot axis of the pivotal arm is mounted on the shackle body and has a bight that can engage in a holding position over the free end of the pivotal arm to hold it in a closed position. This arm can be springy in such a manner that it seeks the holding position, or can be biased by a spring into the holding position. A trip line attached to the stirrup can displace it into a freeing position in which it allows the pivotal arm to swing away from the body and open up the shackle.
