Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts (5a,5b) is ensured.Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automatically to its initial position.

Abstract: A cylinder lock has an external cylinder member and an internal cylinder member inserted in the external member. Further it has an elevatable plate provided with its lower end protruding in a key slot axially formed in the internal cylinder member and a stopper placed on the top arc periphery of the elevatable plate. A key adapted to be used exclusively for exchanging or removing the internal cylinder member is used in a situation that the key is lost and another key having another key code is necessary to use in place of the old key. When the lock is to be opened, the key to be exclusively used to remove the internal cylinder member is inserted into the key slot and the elevatable plate is raised together with the stopper, so that the stopper is disengaged from the internal cylinder member.
Abstract: The present invention comprises a key identification cover having universal adaptability to all manner of conventional keys. More specifically, the key cover of the present invention includes two substantially planar panels linked at their periphery by a hinge means having an aperture therethrough for receiving a key shank, and fastening means for securing the panels together at their periphery as they lie against a key head. Identifier means for identifying the lock for which the covered key is intended are associated with at least one of the panels, and may comprise labels or other markings. The key cover, or at least a portion of the panel carrying the identifier means, is substantially transparent so as to permit the placement of the identifier means in a protected position while enabling the user to view it.
Abstract: A T-handle lock assembly for vending machines or the like include a two-piece cylinder front handle and cylinder/extension rod housing subassembly which interlock by means of first and second asymmetrical flange edges integrally formed on the housing and corresponding recessed slots within the cylinder front handle. A single set screw is threaded into an aperture in the front handle extending in the direction of the slots to engage and rigidly secure the housing to the handle so that the lock cylinder is in alignment with a key access passage in the front surface of the cylinder front handle. The arrangement prevents access to the lock cylinder when in a locked condition even if the set screw is removed.
Abstract: A steering lock system for an automotive vehicle includes a steering lock actuator, a control rod, a solenoid with a corresponding plunger and a portable transmitter which produces a radio signal indicative of a transmitter self-identifying code. When the transmitter self-identifying code matches a preset reference code, the solenoid is energized to move the plunger so as to release an engagement between the plunger and the control rod. Accordingly, the control rod is free to move to a position where no engagement between the control rod and the steering lock actuator is established, to allow the steering lock actuator to shift to a steering wheel unlocking position from a steering wheel locking position.
