Abstract: A locking system for a stop button employed in a mortise lock having a spindle for operating a latch utilizing a first spindle base and a second spindle base which are nested relative to one another. Each base includes an opening for the mortise lock spindle such that the spindle may enter the combined first and second bases from the left side or the right side. A locking hub overrides either the first or second base and is capable of selectively lying over either the first or second base. An abutment linked to the stop button interacts with the locking hub such that either the first or second base may not be turned by the spindle when this occurs. Locking hub selectively locks either the first or second base through its position relative to the same and allows the mortise lock to easily transform from a left-hand version to a right-hand version.

Abstract: Safety lock for doors, gates or the like, comprising a box-shaped body (2) which contains and supports a bolt (5) able to slide between several operating positions (9, 10), actuating means (8) for displacing the bolt (5) between the above-mentioned position, a movable plate (15) capable of engaging by means of engaging means (17) inside seats (14) formed along the bolt (5) so as to retain it in the above-mentioned retracted and projecting positions. The lock (1) also has adjustment means (20) which are accessible from the outside of the box-shaped body (2) and are able to act on the movable plate (15) so as to engage it/disengage it with respect to the bolt (5) so as to allow the latter to be arranged with the part (5a) projecting by the desired length. The movable plate (15) is mounted rotatably on the box-shaped body (2) about an axis of rotation (Z) by means of a pin (19); with respect to which it is able to rotate as a result of the action of adjustment means (20).

Abstract: A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, the turn knob is moved to the locked positioned and then pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the locked position.

Abstract: A multifunction hinged door lock with independently biased lever assemblies positioned one on each side of a door that drive the latch bolt of a latchbolt subassembly through the medium of a drive slide positioned for slidable movement in the sub assembly. The lever assemblies include at least one lock actuator such as a keyed cylinder to optionally displace at least one locking device between locked and unlocked configurations.The subassembly may optionally include an extended length bolt, a detent to restrain the bolt from fully extending prior to latching and optionally also include a detent to restrain the bolt from fully displacing prior to locking. The subassembly may optionally include an extended length bolt with a latching lever to assist initial latching.The subassembly may also optionally include a facility whereby inward displacement of the bolt during latching drives the locking device to the unlocked position if it were actuated to the locked position prior to latching.

Abstract: Door lock and lock assemblies are useful, for example, in vehicle cabs. Latch and lock assemblies of known structures which can be unlocked from inside the cab while remaining locked from outside the cab require complex and bulky linkage assemblies. The subject door latch and lock assembly includes pivotal outer and inner actuator. The pivotal movement of the outer actuator simultaneously pivots the inner actuator to open a catch mechanism. Pivot movement of the inner actuator can be independent of the outer actuator. A locking lever can be pivoted to a locked position to prevent pivotal movement of the outer actuator. Pivotal movement of the inner actuator is not prevented by the locking lever. Thus, the disclosed door latch and lock assembly can be opened from inside the cab while remaining locked from outside the cab without requiring complex and bulky linkage assemblies.

Abstract: A vehicle door lock (106) and latch (104) assembly is provided whereby a key may be used to lock the door (100) and to prevent rotation of the outside door handle (108). A lock handle (116) is provided inside the vehicle door (100) for overriding the key lock (110) to permit the inside and outside handles (114,108) to operate to open the door. Both the key lock (110) and the lock handle (116) when turned operate a linkage (172,168) which is connected to the locking cam (158) enabling the locking cam (158) to be moved between its locked and unlocked positions. Even with the lock handle (116) and the key lock (110) in the locked position, the inside handle (114) can be turned to move the locking cam (158) to the unlocked position and to open the door (100). The outside handle (108) can now be used to open the door also. The outside handle (108) can also be released for operation by turning the key in the key lock (110) to the unlocked position.

Abstract: A mechanism which may be added to existing conventional type cylindrical door locks at the time of manufacture thereof or to such locks already in the field with just a slight modification of the existing lock. The structure of the added security mechanism blocks the throw of the latch bolt and at the same time blocks the retractor to positively prevent opening of the lock by key, turning of the knob, or tampering with the latch. The security device is tamperproof as it is inserted into the interior of the cylindrical lock and can only be disengaged to allow entry from inside the building structure. The lock cannot be opened from the exterior of the door when the security device is engaged, by any conventional method or tampering.

Abstract: A lock mechanism housed in a steel case and directly weldable to iron doors, gates, grilles and similar objects, a bolt slideable in either direction along its longitudinal axis, a fixed member adjacent a long side of said bolt, said fixed member having an opening alignable with a dimple in said bolt side, a sliding member driven in either direction along its longitudinal axis by key or knob operated lock cylinder mechanisms, said sliding member having an opening alignable with dimple in said bolt, a ball retained in opening of fixed member and movable between dimple in said bolt and opening in said sliding member.

Abstract: A lock housing is provided for mounting upon or in a door, but which may also be mounted upon or in a door frame. Latch and bolt bars disposed in side-by-side relation are supported from the housing for lengthwise extension and retraction relative thereto. A locking pawl is mounted on a shaft oscillatably supported in the housing and extending transversely of the inner ends of the latch and bolt bars and the pawl is swingable into and out of position behind the inner ends of the bars when the latter are in their extended positions. A first pair of solenoids are selectively operative on 12 volt D.C. and 110 or 12 volt A.C. current to shift the shaft to a position with the pawl in an unlocked position and the third solenoid is operative to shift the shaft to a position with the locking pawl in the locked position.
