Abstract: A latch structure is provided herein. The latch structure comprises a base, a plate, a rotating element, hooks, a magnetic element, springs, locating posts, a latch element, a pushing element, and screws. One side of the magnetic element is rotatable by the pin, and the other side is mounted with the spring and the locating post. When door is closed inwardly, the pushing element pushes the rotating element forwardly to push the magnetic element contacting with the latch element which are attracting due to the magnetic field. The hooks then engage with the connecting portions. When power is off, spring abuts the magnetic element to release the hook from the connecting portion. The benefit is that as long as the attract force of the magnetic field larger than the pressure of the spring, the hooks and the latch element are decided to engage or separate, increasing the load ability of the latch structure. It is therefore large load ability is acquired only required few attract force, decreasing costs.

Abstract: A cargo seal assembly structured to maintain one or more doors on a cargo container in a closed and latched position comprising an elongated flexible material segment having a distal end, a proximal end and an intermediate portion extending therebetween. The flexible material segment is disposed and structured to extend in surrounding relation to the lock rods an concurrently into sealing engagement with the latch assembly. A lock body is attached to the flexible material segment at a location which prevents removal of the material segment from its operative position. As such unauthorized access to the interior of the cargo container can only be accomplished by destructive separation of the flexible material segment at two separate, spaced apart locations along its length. A single identifying indicia is disposed on the flexible material segment or an operative component associated therewith.

Abstract: A molded thermoplastic body is formed with a rectangular cavity. A molded thermoplastic insert is welded to the body in the cavity and has a top cross member, a stem member and a bottom member. The stem member has a plurality of molded fingers cantilevered on opposing sides inclined relative to the stem member longitudinal axis in one embodiment. The stem member forms the cavity into two channels. A wire shackle which may be round or square in section, a wire or molded plastic, is U-shaped with two legs. One leg is formed with notches to receive the tips of the fingers in one channel and the other leg is formed with a reversibly bent barb which engages the fingers in the other channel on the opposite side of the cavity. The bottom member limits the insertion depth of the legs. The notches and barb engage the fingers and lock the shackle to the body.

Abstract: One end of a stranded steel cable is attached to a cast zinc seal housing having a chamber in which a steel sleeve with a tapered bore is positioned. The sleeve in one embodiment is fixed to the housing in the chamber or may be displaceable and captured in the chamber in a further embodiment. A serpentine clip locking member captured in the housing chamber resiliently radially grips the a second end of the shackle inserted into the sleeve bore and wedges and locks to the cable and sleeve when the shackle is withdrawn. The sleeve precludes damage to the softer zinc housing by the locking member when the locking member is displaced in the housing chamber. Various embodiments are disclosed. In a further embodiment, the one end of the cable exits the housing in a plane different than where the second end enters the chamber to enhance ease of insertion of the second end into engagement with the locking member.

Abstract: A thermoplastic housing has a chamber open at one end and a thermoplastic rotor is locked axially in the chamber by snap fit ridges and grooves. Two pairs of bores on opposite sides; of the chamber are aligned, with one pair connected by a transverse slot. The rotor has two bores aligned with the housing bores and includes flexible pawl teeth which engage ratchet teeth in the chamber. The teeth rotationally lock the rotor relative to the housing in one direction while a seal filament inserted in the bores is wrapped about the rotor as the rotor is rotated in the other direction. The slot permits the filament to be fixed to the rotor when the rotor is rotated 180.degree. causing the filament to traverse the slot and permit the remaining adjacent bores in the same plane as the fixed filament to be aligned and free to receive the filament free end.

Abstract: A one-piece high-security cable type seal-lock having a locking body (10) consisting of: A length of multi-stranded cable (50) having one cable end (51) permanently attached to locking body (10) within a through hole identified as fixed cable hole (11). A longitudinal cylindrical through hole (14) running approximately parallel to fixed cable hole (11) and having a centrally located annular recessed groove, thereby creating center expansion cavity (25). A locking pin (40) is held in place within locking body (10) and positioned approximately perpendicular to, and centrally located above, free cable end (52). When installed, locking pin (40) is forcibly pushed down until it pierces free cable end (52) thereby staking the cable in place and simultaneously creating cable bulge (53). The enlarged diameter of cable bulge (53) within center expansion cavity (25) is unable to be removed from locking body (10) via the lessor diameters of adjacent first guide hole (20) or second guide hole (22).

Abstract: A thermoplastic housing has a chamber open at one end and a thermoplastic rotor inserted in the chamber. The housing wall contains bores aligned across the chamber and two annular grooves in the chamber adjacent the chamber entrance. Tabs are formed adjacent the chamber entrance. The rotor has a bore and two annular ridges near its top. The ridges are relieved complementarily to the tabs. The rotor is inserted and locked axially in the housing by snapping the ridges into the grooves. The tabs are located in the relieved areas to align all of the bores so that a seal wire may thereafter be inserted through the bores. The rotor includes flexible spiral-like co-planar pawl teeth which engage ratchet teeth formed on the housing in the chamber. The ratchet and pawl teeth rotationally lock the rotor relative to the housing while permitting the rotor to bend a seal wire inserted in the bores during rotation which rotation in one direction locks the rotor.

Abstract: An improved security seal includes a plastic housing with a chamber open at one end and a plastic rotor which is insertable in the chamber. The housing wall contains bores aligned across the chamber and two annular grooves adjacent the chamber entrance. Tabs are formed adjacent the chamber entrance. The rotor has a bore and two annular ridges near its top. The ridges are relieved complementarily to the tabs. The rotor may be partially inserted in the housing by snapping the lower ridge into the upper groove and locating the tabs in the relieved areas to align all of the bores so that a seal wire may thereafter be inserted through the seal. The ridge-groove and tab-relief cooperation prevent inadvertent relative rotation of the rotor and housing and full insertion of the rotor. With a seal wire inserted, the rotor and housing are relatively rotated to wrap the wire about the rotor. The rotor is then fully inserted into the housing so each ridge snaps into one groove.

Abstract: Device for tying an elongate object, a cable bundle for example, having a band to be tensioned round the object and a lock connecting the band ends, which exhibits a passage orifice for at least one band end and a bore oriented transversely thereto, which contains a pin to be driven through the band located in the passage orifice. For better securing of the pin in its closed position, the pin and the bore exhibit, on their side facing the object to be tied, catch edges engaging behind each other in the releasing direction of the pin.
