The security sealing mechanism comprises a sealing body including an abutting surface disposed at the end thereof contiguous to the coupling element rows for receiving the slider and locking means provided on the upper surface of the sealing body, and a pull tab having one end releasably jointed to the link pivotally connected to the slider and having the other end adapted for unreleasable locking engagement with the locking means.
Abstract: It is combination lock, in which the main rod is made of steel, while the movable sleeve is made of copper. The main rod is mounted with five combination rings. The lock is to be mounted between the shift rod and the hand-brake handle so as to prevent a burgler from operating the shift and releasing the hand-brake normally.
Abstract: An expansion plug including a cam lever with a securing portion, and a top plate with a flange. A first hole is centered in the securing portion and a second hole is centered in the flange. During engagement of the cam lever, the securing portion adjoins the flange, aligning the two holes. Thus, a lock may be inserted through both holes to securely fasten the cam lever to the top plate.
Abstract: The anti-theft device comprises a strong steel plate (1) having a flat, substantially horizontal section (1a) combined in one piece with fork-shaped, bent section (1b). At the rear end of the plate (1) is an attachment boss (2) which in locking position cooperates with the rear region of a gearbox (9). A lock (4) is welded to the plate (1) between the boss (2) and the slit (7) of the fork arrangement (3), said lock being a double locking cylinder (5) which is applied in the channell (10) of the gearbox (9) and is turned to a position below the upper limiting wall of the gearbox (9) when the key is turned. In locking position the end edge (6) of the slit (7) in the fork arrangement (3) is in the immediate vicinity of the gear lever (8) and locks this in parking position. The anti-theft device is simple to install and can easily be removed from the vehicle.
Abstract: A lock for cabinets wherein a lock component is attached to one element of the cabinet and a counter-locking component is attached to another element. The lock component includes a hook-shaped latching bolt which is slidable and swivelable to become engaged with and disengaged from the counter-locking component. The latching bolt is held in a latching position by a locking bolt part of a permutation lock, and also by a retaining mechanism in the form of a heart-shaped endless cam slot which effects a release of the latching bolt only in response to a displacement of the latter in a door-closing direction.
Abstract: Sliding doors of showcases are normally locked by safety locks, the installation of which must, however, be very precise when a play of the sliding door in rest position is to be avoided. By the new device a safe locking of a showcase is also to be achieved without having to pay attention to an especially precise installation. The sliding door (4) is held in the closed position and rest position, respectively, by permanent magnets (7) provided at the showcase, the magnetic force of which can be neutralized by an electric coil and direct current flowing therethrough. As the installation of the permanent magnets must not be so precise, such a showcase can be built up also outside a workshop, for instance on the building site. Furthermore, in this way the safe closure of sliding doors can be achieved when at positions where known locking means are difficult to reach.

Abstract: A latch mechanism for a door or the like includes first and second rotatable latch operating members which operate a latching bolt or the like. An axially movable square section spindle extends through complementary holes in both members. In an engaged position, the spindle operates both members when rotated. In a disengaged position, a circular section portion of the spindle registers with a hole in one of the members. In the disengaged position the bolt can be operated by the first member even though the second member may be prevented from rotating by means of pins. The spindle can be moved between engaged and disengaged positions by a push-rod extending out of the door. Thus, when the second member is locked it may be overriden by actuation of the rod and the first member.
