A latch assembly for closing a door of a glovebox compartment includes a key cylinder having an eccentric shaft; a striker connected to the key cylinder to form a scotch-yoke connection to the eccentric shaft so that a rotation of the key cylinder is transformed to a linear movement of the striker; and a pair of latching members to lock the door. The pair of latching members includes a first latching member having an operation portion to engage or disengage from the striker, and a second latching member connected to the first latching member to simultaneously move with the first latching member. The key cylinder rotates to switch between an unlocked state in which the striker engages the operation portion and a locked state in which the striker is disengaged from the operation portion.

A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.

A mechanism for selectively coupling a first moving part with a second moving part. The mechanism includes and engaging member that is movable between a detent position, a uncoupled position, and a coupled position in which the load transferring surface is within the aperture. A biasing member biases the engaging member into the detent position or coupled position. The engaging member overrides the biasing force and moves out of the detent position into the uncoupled position when first and second moving parts move relative to each other. When the engaging member is in the coupled position, the first and second moving parts are coupled for movement together. One embodiment of the invention is a child safety door handle rotating on a spindle. Other embodiments include water faucets, stove or burner controls, or any other rotatable or movable parts.

A device for blocking the pull-out movement of pull-out furniture parts including, for each of the pull-out furniture parts, a driver, a blocking unit which has a shiftable actuating, and a retraction spring and blocking rods which cooperate with the actuating parts, a respective actuating part that is shifted due to movement of the driver when the pull-out furniture part is pulled out and that displaces a blocking rod in a longitudinal axis direction, the blocking rods being blocked from any further axial displacement by a stop. Each of the blocking units has a pivotable catch arm that swivelable about a stationary pivot axis lying parallel to the longitudinal axes of the blocking rods and is loaded by the refraction spring, the catch arm being pivoted by the driver from an initial position to a final position when the pull-out furniture part is pulled out, thereby shifting the actuating part.

A door interlock device for a power transformer room in a vacuum circuit breaker includes a cam disposed on a shaft of a ground switch, a supporter disposed on a side plate of a power transformer room, a shaft disposed at the supporter to be slidable and having one end contacting the cam to be upward and downward movable, a spring disposed within the supporter to provide an upward elastic force to the shaft, and an interlock plate disposed at one side of the power transformer room door and configured to be in contact with the shaft.

This invention relates to a latch (preferably a slam latch) and to methods of operating a door/gate/panel using the latch. The latch comprises: (i) a mounting body; (ii) a latch bolt mounted relative to the mounting body for movement between a locking position and an unlocking position, said latch bolt having a keeper-engaging region extending from the mounting body and terminating at a keeper-engaging end; and (iii) a keeper having at least a first wall and a second wall which are spaced to define an opening for receiving the keeper-engaging region, wherein the first and second walls are adapted to engage the keeper-engaging region of the latch bolt when the latch bolt is in the locking position.

Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

A door lock assembly for use with a door comprising a movable locking assembly disposed within a recess formed in an edge of a door panel having one or more movable wedge shaped locking elements disposable between a locked position and an unlocked position and having first teeth associated therewith, and a frame member having a channel and second teeth associated therewith, wherein when assembled the locking element is disposed substantially within the channel formed in the frame element when disposed in the locked position, and wherein one or more the first teeth of the locking element are adapted to selectively engage with one or more of the second teeth when a force is applied to the door.

A locking system is mounted to a door with three rods extending therefrom. The rods have a locked position extending beyond the periphery of the door and an unlocked position not extending beyond the periphery of the door. Three rod receivers are adapted to receive the three rods in the locked position. A handle rotatably engages cam plates which are operatively engaged with the rods whereby rotation of the handle rotates the cam which moves the rod ends from one position to the other. A locking tab extends forwardly from the lower cam plate into a recess and is engaged by a circular lock while the recess prevents movement of the engaged circular lock. A second locking tab extends forwardly from the rod-locking link and a stationary locking tab is aligned thereto. Both locking tabs are engaged by a padlock preventing movement of the rod-locking link.

A delayed return mechanism, such as for a door latch, including a housing having a hole with an axis, a cavity in the housing at least partially filled with a fluid media, a hub disposed in the cavity including a spindle hole coaxial with the hole in the housing including teeth within the spindle hole to engage a spindle, the hub being rotatable about the axis and having a fin extending radially outward in the cavity, and a channel through which the fluid media passes during rotation of the hub to control flow of the fluid media about the cavity.
