Abstract:
A high strength, low strap insertion force cable tie having a locking head that locks the distal ends of a strap in two strap positioning channels in the head with two metal barbs each carried by a pawl hingedly mounted to a side wall of the head.
Abstract:
A positive, secure two-loop restraint for law enforcement is light-weight, strong, inexpensive and disposable and which may be attached to the wrists or ankles to be used in place of traditional handcuffs. The restraint is formed from a single elongated, substantially flat plastic strap having a pair of closely spaced socket clasps centrally located therein generally mid-way between first and second strap extremities. The extremities are insertable through openings in the socket clasps which are perpendicular to the plane of the strap and when receiving the extremities form double loops with the strap ends extending parallel to each other when the loops are formed by positioning the extremities through the socket clasps. Each of the extremities has a toothed surface whose teeth all slope in the same direction, and each socket includes a latch stop extending in the same direction as the slope of the teeth for permitting the stop to ride over the teeth during insertion movement and preventing extraction movement, thereby providing a flat ratchet arrangement such that a two-loop restraint is provided, with the sizes of the loops being adjustable in the same direction and which are formed and positioned on wrists or ankles of the restrained person when the extremities are inserted in the same direction through the socket clasps. The straps are made of a high density plastic, are light-weight and a large number may be conveniently carried by a law enforcement user as contrasted with bulky, expensive, heavy and difficult to use handcuffs.
Abstract:
A self-locking cable tie for forming a plurality of wires or the like into a bundle. The tie comprises a stretched elongate flexible strap portion for positioning about the wires. The strap portion is made of a plastic material comprising stretch-oriented molecules. An integral head portion extends from one end of the strap portion and has a strap entrance face, a strap exit face, and a generally transverse aperture extending from the strap entrance face to the strap exit face for receiving the distal end of the strap portion. The aperture has a predetermined strap path therethrough. The tie also includes a locking means non-integral with the head portion and which has a free end portion extending into the strap path and toward the strap exit face. The free end portion and the strap portion each have an engageable component for causing a localized stress concentration in the strap portion. Insertion of the distal end of the strap portion into the aperture from the strap entrance face causes the strap portion to interfere with and to deflect the free end portion to permit tightening of the tie around the wires. The engageable components cause the localized stress concentration in the strap portion upon application of withdrawal forces to enable the free end portion to pierce the strap portion and prevent retrograde movement thereof.
Abstract:
D R A W I N G THE INVENTION IS DIRECTED TO A TAMPERPROOF SEAL WHICH CAN BE INSTALLED OR REMOVED WITHOUT TOOLS AND WHICH READILY SHOWS WHEN THE SEAL HAS BEEN TAMPERED WITH. THE SEAL IS COMPRISED OF AN ELONGATED BODY PORTION COUPLED BY A WEAKENED PORTION TO A SEAL PORTION. THE SEAL PORTION EXTENDS TO A LOCKING HEAD MEMBER, SHROUDED SUCH AS TO PREVENT THE INTRUSION OF TOOLS OR OTHER DEVICES ONTO THE HEAD TO UNLOCK THE SEAL. EXCESS PRESSURE UPON THE SEAL RUPTURES THE WEAKENED PORTION TO SHOW TAMPERING.
