A locking assembly comprising a fastener having a locking stud having a locking cavity and an aperture for receiving the locking stud, a lock having material adapted to contract when activated and having jaws adapted to engage the locking cavity of the locking stud when received in the aperture, and an unlocking mechanism comprising rotating body having an opening for a key.

A fix position device for casement latch includes a housing including a cavity, a through hole, first and second limit members, a hole having one end communicating with the cavity and the other end formed with threads, a spring biased steel ball in both the hole and the cavity, and an adjustment screw secured to the threads; a bolt including a cylindrical axis partially in the through hole, a channel having a square section and formed through the axis, two recesses on a periphery of the axis, and an engagement member at the other end; a cover plate including a central hole with the axis partially disposed therein; a face plate including an intermediate slit with the engagement member passing through; and a handle assembly including a peg member having a square section projecting through the channel, and a lever having one end co-rotated with the peg member.

A low profile actuating window lock for casement windows having a longitudinal slot in a sidewall of the casing for the lock, wherein a fork component translates within the slot in a direction perpendicular to an axis of rotation of the handle and the handle rotates along a plane perpendicular to the fork component, the handle pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle and restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

A position holding device for a rotating lever includes a rotating lever and a torsion spring. The rotating lever is elastically held at two positions, that is, a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part. The first arm part has a mountain portion formed thereon, and the second arm part has a reversely urging portion formed thereon. An urging force of the reversely urging portion is applied to the rotating lever as a braking force against an urging force of the mountain portion. Further, a regulating member is formed on a base member so as to abut against the first arm part when the rotating lever rotates toward the first position through a neutral position.

A key cylinder device includes a key cylinder attached inside a cylinder portion of a cylindrical mounting member and locked/unlocked by a mechanical key, and a packing insertion portion that is integrally formed on an outer surface of the key cylinder so as to have a shape without an undercut portion and includes an opening for insertion of a packing member in a vertical direction along the outer surface.

A low profile actuating window lock for casement windows having a handle actuate a lifter that slides vertically on a fork component in slidable communication with the window lock casing, the handle pivotable about the lifter and pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle, lifter, restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

The invention relates to a lock with an improved locking system, including a lock block attached to a support by means of at least two fastening screws, with a door arranged between the lock block and the support, the lock including grub screws screwed into the support, which project from the support by a length according to the portion of grub screw screwed into the support, such that the length matches a clearance between the door and the support.

A lock and a home appliance having the same are disclosed. The lock includes a holder provided at one selected from between the cabinet and the door, a housing provided at the other selected from between the cabinet and the door, a first stopper provided at the housing, a fastening unit separably coupled to the first stopper so as to be coupled to the holder when separated from the first stopper, an actuation unit configured to reciprocate in the housing, the actuation unit being configured to be moved away from the introduction port in the state of contacting the holder when the door is moved so as to close the introduction port, the actuation unit being configured to separate the fastening unit from the first stopper while being moved away from the introduction port, a first elastic member for providing force necessary to move the fastening unit away from the introduction port when the fastening unit is separated from the first stopper, a second elastic member for providing force necessary to move the actuation unit toward the introduction port, and an actuation unit lock for fixing the actuation unit to the housing when not in contact with the door and releasing coupling between the actuation unit and the housing when in contact with the door.

An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.

A lock cylinder includes a housing, in which a sleeve having a cylinder core accommodated therein is rotatably supported. The cylinder core has spring-loaded tumblers forming a form closure with recesses arranged in the sleeve when a key engaging the tumblers is removed. Inside the housing, the sleeve is coupled to a coupling element by means of a disengaging sleeve. The coupling element is supported inside the housing and connected to a bearing in a rotationally-fixed manner. The bearing supports an output element. At least one of the sleeve and the coupling element forms a form closure with the bearing to block the rotation of the output element if an improper object is used in operative connection with the cylinder core.
