A lock mechanism according to an embodiment includes an engaging portion, a hook, and a pressing portion. The engaging portion is provided in any one of a housing and a door that is configured to open and close a housing opening portion of the housing. The hook is provided in the other one of the housing and the door to be rotatable around a rotation axis, is engageable with the engaging portion, and is normally disengaged from the engaging portion by its own weight. The pressing portion is provided separately from the hook and is configured to press the hook. The hook includes a hook side engaging portion that is configured to engage with the engaging portion with the rotation axis interposed therebetween, and a hook side pressing portion that is configured to cause the engaging portion to engage with the hook side engaging portion by being pressed by the pressing portion.

A locking mechanism comprises a base comprising a pair of arms projecting therefrom and defining an open mouthed recess for receiving a member to be selectively retained in the recess. The mechanism further comprises a pair of locking elements mounted between said pair of arms for rotational movement between a retracted position in which they permit access to the recess and an extended position in which they extend at least partially across the mouth of the recess. The arms comprise respective guides to guide the movement of said locking elements between said retracted and extended positions. The mechanism further comprises a drive for simultaneously moving the locking elements in opposite rotational directions. The drive may comprise a drive shaft having left handed and right handed threaded portions.

In a work vehicle of the present invention, a load carrying bed includes a floor panel, a pair of left and right side panels, and a rear gate which is openable and closable. The rear gate includes left and right lock operational portions for maintaining the rear gate under a closing posture through engagement with locking engagement portions formed in the left and right side panels, a single handle disposed at an intermediate position in the left/right direction of the rear gate and supported to be pivotable about a horizontally oriented operational axis X, and left and right operational wires for operating left and right locking members in a direction for pulling these locking members out of the locking engagement portions by an operation of the handle about the operational axis X.

A latch mechanism is provided that includes a housing, a cap, and at least one indicator. The cap may include a central axis and may be mounted for selective rotational movement relative to the housing about the central axis between a latched position and an unlatched position. The at least one indicator may be interposed between the cap and the housing, such that the cap is in covering relationship to at least a portion of the at least one indicator. The at least one indicator may also be mounted for radial movement outwardly from the central axis relative to the cap as the cap is rotated from the latched position to the unlatched position such that the cap is no longer in covering relationship to the portion of the at least one indicator.

A compression latch assembly for latching a panel to a frame includes a housing assembly, a lockplug assembly, a handle actuator assembly, and a rotating pawl assembly. The housing assembly defines an exterior well and a first and second compartment. The lockplug assembly resides within the first compartment and includes a lockplug having a circumferential guide surface. The handle actuator assembly has a handle within the exterior well, a crank coupled to the handle, and a drive shaft coupled to the crank. The handle and the crank rotate about common pivot point within the second compartment. The handle is selectively captured and ejected by interaction between the circumferential guide surface and a locking pin on the handle. The rotating pawl assembly has a hook defining a slot that receives the drive shaft. Pivotal movement of the handle actuates the hook by movement of the drive shaft within the slot.

A sliding door lock system has a centrally-disposed operator. The operator has a casing with a trigger retractably extended from the casing. An operator mechanism disposed in the casing is operatively engaged with the trigger. A lock remotely disposed from the operator has a housing. A pair of opposed locking hooks extend from the housing and a spring biases each hook into an unlocked position. A block pivotably connected to the housing is configured to engage the hooks when the hooks are in a locked position. An elongate member operably connects the operator mechanism to the block.

A door-locking device for a self-cleaning oven includes a support configured to be fixed to a frame of the oven. A main slider is movable relative to the support along a longitudinal rectilinear direction, and is configured to be pushed elastically towards an extracted position and pushed by the door of the oven towards a retracted position. A locking arm is coupled to the support around an articulation axis perpendicular to the longitudinal rectilinear direction and oscillates around the articulation axis between an unlocked position and a locked position. A transmission mechanism connects the locking arm to the main slider and is arranged to swing the locking arm from the unlocked position to the locked position and vice versa via movement of the main slider from the extracted position to the retracted position, and vice versa. An electromagnetic switch includes an electromagnet that drives a movable member associated with a locking pin arranged to lock the main slider in the retracted position.

A fence system with a gate assembly mounted in a gap between first and second fence portions of the fence system. A hinge may be used to mount the gate assembly, where the hinge has a clamp fixed to a support with substantially the same cross-section, and the support is fixed to a first member of the hinge. A second member of the hinge can be mounted to the gate assembly with the first and second members being rotatably fixed together, thereby allowing rotation of the gate assembly between open, closed, and various other positions. A latch actuator can selectively secure and release a latch retainer thereby selectively allowing the gate to rotate to the various positions. A handle can be positioned proximate the latch actuator to allow gripping of the handle and manipulating the actuator with one hand, thereby releasing the retainer.

The invention relates to a lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with compartment doors (2) which are to be opened individually, and to an automatic storage machine having at least one such lock (1). The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2).
