A combination lock can be operated manually via the manipulation of dials and by way of an electronic key. The lock includes one or more rotatable selectors each having multiple indicia disposed thereon. Rotation of the rotatable selectors to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a closed position and a second position in which the lock is in an open position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

A molded access door assembly for an access opening in a covering material of a wall or ceiling is disclosed. The door assembly includes a frame defining a frame opening. The frame is positionable against the covering material with the frame opening in alignment with the access opening. The frame includes a lip extending about a perimeter of the frame opening for bearing against the covering material adjacent the access opening, and a plurality of fastener holes passing through the lip for receiving fasteners to secure the frame against the covering material. The door assembly further includes a molded door hingedly connected to the frame. The door is movable between an open position providing access to the frame opening and the fastener holes, and a closed position in which the door covers the frame opening and an entirety of the fastener holes.

One-piece sliding block consisting of plastic, in particular for locking tongues of fittings, comprising a base portion, wall portions and a cover portion, wherein the cover portion overlaps a subregion of the base portion so as to form an insert opening for a component that can be operatively connected to the cover portion, and wherein latching means which are moulded onto the cover portion are provided in the region of the sliding block.

The invention is related to a locking mechanism (A) which enables the attachment of the covers (B) on military vehicles having different thicknesses to the body (C) of the vehicles. The invention is characterized in comprising a locking pin (10) having a partial or complete screw structure; a lock bolt (70) which is coupled to the locking pin (10) and whose tightening distance is determined depending on the length of the locking pin (10) screw length thereon, which transfers the motion at the rotation direction (W) of said locking pin (10) as a vertical motion and which locks the cover (B) to the body (C) and then releases said cover (B) by means of the rotation motion received from the locking pin (10), a lock body (40) which forms a border to the lock bolt (70) and allows the required tightening force to be applied to the locking pin (10), which limits the motion of the stop surface (41) and the lock bolt (70) at the rotation axis (W), having the opposite stop surface (42) thereon and on which all of the components of the locking mechanism (A) is positioned, and a pressure spring (50) which is positioned on the locking pin (10) and creates pressure between the locking pin (10) and he lock bolt (70) and allows that lock bolt (70) to rotate at the same time when the locking pin (10) is rotated.

A device for locking a pivotal protective device, such as a safety bracket or a weather protection hood, of a chair for a chairlift. The device has interacting projections, one of which is connected to a frame of the chair and the other of which is connected to the protective device. At least one of the projections is resiliently mounted, and the projections are equipped with sliding surfaces which produce a deformation of the resilient bracket after a defined force has been applied to the safety bracket and allow the projections to slide past one another in both directions.

A utility cart with lock box which includes a fixed housing portion mounted to the top of a cart storage unit, and a rotating housing portion rotatably mounted to the fixed housing portion. The fixed housing portion includes spaced sidewalls joined to a clear see through arcuate back wall, and an open front. The rotating housing portion includes spaced sidewalls joined to a clear see through arcuate front wall, and an open back. The rotating housing portion is dimensioned such that it can be rotated rearwardly up and over the fixed housing to provide access to items stored in the fixed housing portion, or under the closed rotating housing portion. Alternatively the rotating housing can be rotated forwardly and downwardly to enclose all items in the lock box. The items located in the lock box are visible whether the box is opened or closed.

A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.

A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.

A latch is provided for latching the doors of cubicles or stalls provided in public washrooms. The latch includes a body mounted within a cavity formed between the inner and outer door surfaces, the body rotatably mounting a spindle having a latching member mounted at one end. Biasing means in the form of one or more cam followers acting on a corresponding number of cam surfaces is provided between the body and the spindle to hold the spindle in a closed position but, once displaced from the closed position, to bias the spindle toward a fully open position.

The invention relates to a closure system, comprising a locking arrangement, in particular a rotary latch arrangement having an evaluatable door contact, for controlling a display device such as a LED module, comprising a sliding shoe, which is to be placed on the locking tongue of a rotary latch mounted in a door, for running onto a sliding ramp supported by the door frame , wherein said sliding shoe includes a housing with a recess for the insertion of alternatively a magnet or a magnetic field sensor acting in a contactless manner.
