  • Patent number: 11619068
    Abstract: The lock according to the invention is meant for locking cabinets, vaults and different machines. The lock has a lock frame, which comprises a bolt. A lock cylinder has been arranged in connection with the lock frame. The lock frame further comprises a power transmission mechanism between the lock cylinder and the bolt. The power transmission mechanism comprises a transmission lever and a latch. The transmission lever additionally comprises a retaining protrusion. The bolt comprises a locking pin and the lock frame additionally comprises a hole for the locking pin. The lock is arranged to allow movement of the lock cylinder and the power transmission mechanism in the direction of the longitudinal axis of the lock cylinder due to an external hit or drilling of the lock cylinder, whereby the movement in the direction of the longitudinal axis moves the retaining protrusion away from the locking pin. Thus, the end of the locking pin moves into the hole in the frame.

  • Patent number: 8360482
    Abstract: A dead bolt latch (10) readily adjustable between forward and rear backset positions. A bolt casing (56) connects to a faceplate (48) installed on an outer face of a door (D). A bolt (15) fitting within the casing extends and retracts to latch or unlatch the door. A latch operator (12) and the bolt casing each have slots (64, 78) of a length corresponding to the distance between the backset positions, and a spring (72) seats between the bolt and latch operator. When the latch is being installed and needs to be adjusted between backset positions, the installer blocks movement of the bolt and then, by turning the latch operator, moves the relative position of the latch operator and bolt between backset positions using the force of the spring. This facilitates latch adjustment even by relatively unskilled installers.

    Abstract: An adjustable door latch that enables one to adjust its length without removing any functionality from other areas of the door latch assembly. The improved door latch assembly includes a strike plate, adjustment head, adjustment stem, resilient member, and housing. The improved door latch utilizes a threaded adjustment head, which is screwed into an adjustment stem. The adjustment stem has a threaded aperture located on the front surface of a circular disc. The circular disc has at least one rib, which fits into the groove of a drum, this configuration prevents rotation of the circular disc when adjustment is necessary. The adjustment member and stem have apertures that allow one to thread the spindle of a door knob through the door latch assembly and to the other door knob.

  • Publication number: 20090152875
    Abstract: A lock assembly comprises a housing and a latchbolt including an attachment member. A retractor element is disposed within the housing for linear reciprocating movement. The retractor element includes a first attachment location at a first position relative to the axis of reciprocation of the retractor element and a second attachment location at a second position relative to the axis of reciprocation of the retractor element. The second attachment location is spaced from the first attachment location by a distance along the axis of reciprocation of the retractor element. The attachment member of the latchbolt is selectively engageable with the retractor element at either the first attachment location or the second attachment location for movement together with the retractor element. An operator is operatively connected to the retractor element for facilitating selective reciprocation of the retractor element for moving the latchbolt between a latched position and an unlatched position.

  • Publication number: 20080185830
    Abstract: A support mechanism for a collapsible steering column assembly having a rake adjustment is provided. The steering column assembly includes a mounting bracket and a column jacket pivotably attached to the mounting bracket for rotation about a rake axis. The support mechanism includes a rod pivotably coupled to the column jacket and a clamp pivotably coupled to the mounting bracket and interconnecting the rod and the mounting bracket. The clamp permits movement of the rod therethrough during collapse of the steering column assembly in only one direction, and is offset from the rake axis. Accordingly, the clamp prevents backward movement of the rod therethrough, thereby preventing rotation of the column jacket about the rake axis post collapse of the steering column assembly to support the column jacket in an elevated position.

  • Publication number: 20070205606
    Abstract: A dual backset latch assembly includes a housing, a latch, a casing, a transmission member, an auxiliary plate, and a retractor. The retractor and the auxiliary plate are jointly movable for selective engagement with one of first and second mounting positions in a slot of the casing corresponding to shorter and longer backset lengths. When the retractor is in the first mounting position, a first mounting hole and a second mounting hole of the casing are respectively aligned with a first through-hole and a second through-hole of the auxiliary plate and respectively extended through by two mounting posts. When the retractor is in the second mounting position, a third mounting hole of the casing is aligned with the first through-hole of the auxiliary plate and extended through by one of the mounting posts, with the other mounting post extending through the second through-hole of the auxiliary plate.
