  • Patent number: 5044587
    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.

  • Patent number: 5040392
    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.

  • Patent number: 5037050
    Abstract: A display mount includes a pair of interlocking portions. An aperture or slot is defined in one portion and a protrusion is formed in the other portion. During assembly, the protrusion is inserted into the aperture or slot. To retain the protrusion in the slot, the protrusion is formed with an enlarged element, and a resilient tab prevents disengagement of the enlarged element from the aperture or slot. The enlarged element, for example, has a ledge defining an underside surface and an outer surface above the underside surface. The resilient tab is disposed adjacent the aperture or slot so that the outer surface of the ledge abuts against the outer surface of the tab to deflect the tab inward during assembly, to release the tab when the enlarged element is moved within the aperture or slot, and to prevent disengagement of the protrusion from the aperture or slot by interference of the underside surface of the ledge with an inner surface of the tab.

  • Patent number: 5036687
    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.

  • Patent number: 5035126
    Abstract: A latch for securing the door of an animal cage or cell which comprises a cylindrical metal barrel having an open end internally screw threaded, and an opposite end internally constricted for holding the terminal of a cable which is interposed in slideable relation into the constriction. The cable is constructed to bind the cage door frame to the door post. The other end of the cable terminates in a loop which fits into a biased slot near the end of the metal barrel. A key interposed from the open end engages a screw threaded arbor stud, rotating it to move along the inner axis of the barrel. The screw threaded arbor stud has an axial projection at its inner end which penetrates the loop and holds it in place in fully locked position. When the key is removed from the barrel, the screw member is inaccessible and cannot be loosened, until the key is reapplied by an attendant or keeper to re-engage the arbor stud, releasing the loop of the cable.
