  • Patent number: 6688657
    Abstract: A dual hinge door assembly is provided that enables selective opening of one side of a two sided door or removal of the door. The two sides of the door have identical assemblies that connect via a horizontal bar. Actuating a switch causes the bar to move horizontally in one of two directions. Movement of the bar causes assemblies on each side of the door to rotate and translate the horizontal motion of the bar to vertical motion of a set of lock pins, and causes the handle on the side of the door selected for opening to become visible to the operator. Upon pulling the handle, the side of the door adjacent to the lock will open while the opposite side remains stationary. Alternatively, the assembly may be modified to cause both handles to release. The operator may then pull both handles to remove the door from the housing.

    Abstract: A locking system for a door for use in conjunction with a commonly available locking mechanism has an interconnecting rod attached to one end of the primary sliding bolt of the locking mechanism, and at the other end to a pivoted link. A draw bar extends from the pivoted link to other pivoted links that are each attached to an additional sliding bolt. As the primary sliding bolt is extended outwardly from the edge of the door via the locking mechanism, the interconnecting rod communicates this motion via the pivoted links and draw bar to each of the other sliding bolts, thereby causing these sliding bolts to extend from the edge of the door in a like manner. Similarly, as the primary sliding bolt is retracted, the reverse process occurs and the secondary sliding bolts retract into the edge of the door.

  • Patent number: 4429908
    Abstract: By providing a single biasing element (spring) connected through pull rods to toggle means in laterally-inverted relationship, there are overcome the problems of (1) inequality of forces on the latching beams and (2) the need for relatively massive springs. The toggle means provide a force-multiplying effect. Moreover, no special actuating element is required for latching or unlatching.

  • Patent number: 4335909
    Abstract: An articulated linkage locks the various access panels, covers, and plates opening into an engine and its accessories. A spring loaded shaft is used to drive a bell crank and a set of catch bolts. Each catch bolt is matched with a catch plate joined to one of the panels, covers and plates granting access to the engine and its components. A pair of doors covering the instrument panel is used to reposition the spring loaded shaft and bell crank. Locking the doors together therefore locks the catch bolt and catch plates together in one stroke and with one lock.

  • Patent number: 4257647
    Abstract: A latch assembly for a pivoted vehicle seat (14) which provides sufficient locking capability to permit a seat belt (15) to be mounted on the frame (10) of the seat as opposed to the base (16) of the vehicle. The latch assembly includes two slidable horizontally spaced apart latch blocks (20,20') mounted on the frame (10) of the seat (14) for engaging base mounted catches (22,22'). Two actuator arms (48,48') coupled to the frame, are operatively connected to each latch block (20,20') and are secured to and positioned by an operator actuated release member (36). Movement of the actuator arms (48,48') causes the latch blocks (20,20') to disengage the base (16) mounted catches (22,22') substantially simultaneously.

  • Patent number: 4193618
    Abstract: Valve means associatable with free traveling spherical means are sealing engageable onto and wipable off of companion seats to selectively control flow. A spool permits selective movement of the head means to the seat means and selective engagement of the head and seat means upon shuttling.An interface assembly comprises means which are extendible to the spool and a piston head element within the housing and carried around an extension for travel along the extension in response to pressure variation. The piston head is shiftable in a first direction in response to fluid variation for travel along the extension for transfer of the spherical means within the piston from one camway to another camway without movement of the spool within the housing.

  • Patent number: 4011741
    Abstract: A lock cylinder with dual driver whereby an independent drive for the dead bolt mechanism and the door latch mechanism may be achieved with a single lock so as to provide withdrawal of both the latch bolt and the dead bolt by rotation of the key inserted into the lock cylinder. The drive for the dead bolt actuating mechanism is a conventional lost motion drive extending from the rear of the cylinder assembly. In addition, a cam is coupled to the cylinder assembly threaded cap so as to provide a direct drive thereto, with a cam being coupled to the latch mechanism so that both the dead bolt and the latch bolt are retracted upon rotation of a key in the lock.

  • Patent number: 4005886
    Abstract: A flush bolt mechanism is disclosed for latching the inactive one of a pair of swinging doors, the mechanism functioning to latch the closed inactive door in response to closing of the other door. The latch mechanism includes a bolt that is driven home by cam and spring assemblies. A heat-responsive mechanism is provided for retaining the bolt in its extended position when the heat-responsive mechanism is subjected to a temperature and for a time sufficient to melt one of its components. A release mechanism may be provided for retracting the extended bolt in response to a force of preselected magnitude applied against the inside of the inactive door.

  • Patent number: 3999789
    Abstract: A lock of the type enabling panic exit, there being a unique drive arrangement from the inner knob to the latch bolt mechanism and the security dead bolt mechanism. This drive utilizes a vertically reciprocable slide at the inside of the door panel, biased in one direction, and shiftable in the other direction by rotation of the inner knob for retraction of both the latch bolt and the security dead bolt. The drive is not responsive to tampering with the spindle elements, e.g. after forced removal of the outside knob. The lock can be employed on either left or right-hand door arrangements, directly, without requiring handing.
