Sliding Bolt With Sliding Operating Means Patents (Class 70/DIG80)
  • Patent number: 5974842
    Abstract: A locking slide latch comprises components that are easily assembled without the need for separate fasteners or adhesives. A presently preferred latch comprises a housing, a pawl received within the housing and an actuating member associated with and slidable relative to the housing for displacing the pawl from an extended position to a retracted position. These components are assembled together without the use of separate fasteners or adhesives, thereby simplifying assembly and allowing for interchangeability of parts to meet varying latch requirements. The latches are preferably manufactured from corrosion resistant materials such as plastics, composites and corrosion resistant metals, and are highly suitable for use in automotive, recreational vehicle and marine applications.

  • Patent number: 4782675
    Abstract: Lock assembly particularly suitable for use on rental storage spaces and the like. The assembly includes a lock bolt which is movable between extended and retracted positions and a slide plate which can move with the bolt. The slide plate is normally locked in a fixed position by a lock which is controlled by the owner of the rental space. The renter can lock the bolt to the slide plate to secure the space. The owner-controlled lock permits the owner to release the slide plate and retract that plate along with the bolt to gain access to the space with the renter's padlock in place. This lock also permits the owner to lock the bolt in the extended position so that the renter will no longer have access to the space even though he may remove his padlock.

  • Patent number: 4676081
    Abstract: The panel lock comprises an elongated housing having resilient wedging means at each end to secure the panel lock in place in a recess in a door, panel or like member. Formed integrally with the elongated housing are a lock housing with a cylindrical opening, a central recessed portion, and a bolt housing. A lock is rotatably secured in the opening in the lock housing. A bolt is slidably positioned in the bolt housing. A spring is operative between the bolt and the bolt housing to bias the bolt outwardly from the bolt housing into locking position. An actuator is slidably secured to the elongated housing and is adapted to engage the bolt. When the actuator is moved in one direction, the bolt is biased outwardly to a latching position by the spring. Movement of the actuator in an opposite direction will move the bolt against the bias of the spring to a release position. Cam means are secured to the lock and are rotatable therewith to lock or to release the actuator.

  • Patent number: 4583381
    Abstract: A compact push-pull right-angle lock especially suited for use on patio doors and on windows has a cylindrical bolt with rack teeth on its central section, a barrel lock assembly, and a rotatable disk all contained in a horizontally split case. The bolt can be extended in either direction by the right angled linear motion of the barrel lock assembly. Linear motion of the barrel lock assembly is transferred to linear motion of the bolt through a disk that is free to rotate some fifty degrees about a shaft. The barrel lock assembly is loosely linked to a crank pin set perpendicularly to the plane of the disk and the bolt rack is meshed with an arcuate section of a pinion gear on the disk located some ninety degrees from the crank pin. The bolt can be locked in either extended position by means of a cam lug which cna be moved from the barrel lock assembly housing into locking recesses in the case by rotational movement of the keyed barrel lock.

  • Patent number: 4305609
    Abstract: A door lock for attachment to a door which can move into a position adjacent to a jamb having a door strike. The lock includes a support member formed from a pair of spaced, generally parallel sides and an end wall interconnecting the sides. The sides and end wall are adapted to enclose a recess cut in the edge of the door. A shiftable lock bolt is carried between the sides and movable through an opening in the end wall and into locked relationship to the door strike when the door is in a closed position.

  • Patent number: 4163375
    Abstract: A lock has a bolt and a key-operated barrel at right angles, and with their axes coplanar. A pinion has teeth which engage teeth on the bolt and teeth on an extension of the barrel. The pinion, bolt and barrel are in a longitudinally split housing, held together by screws, the pinion having a slot to receive one of the screws. The barrel lock moves a latch plate transverse to its axes, so as to extend into a slot in the housing to prevent movement of the barrel.
