A bolt module is disclosed. The bolt module comprises: a bolt moveable between a thrown position and a retracted position; an anti-thrust member moveable between a release position in which the bolt can be retracted and a plurality of blocking positions obstructing driving back of the bolt under action of an external force on the bolt and, a first rotor assembly capable of accepting a drive element, the first rotor assembly arranged to drive the bolt and to move the anti-thrust member between the plurality of blocking positions and the release position. Each of the plurality of blocking positions may respectively limit to different extents the driving back of the bolt under action of an external force on the bolt. There is also disclosed a leaf or door comprising the bolt module, wherein the bolt module is mounted on the leaf or door for securing the leaf or door.

A hinge lock for locking a door leaf with respect to a door frame and for pivoting the door leaf with respect to the door frame. The hinge lock has a first hinge element for arranging on the door leaf and a second hinge element for arranging on the door frame. The first hinge element and the second hinge element can be locked with respect to one another by means of a bolt which can be moved back and forth in a locking direction between an unlocking position and a locking position and the locking position by means of a drive rod which can be moved transversely to the locking direction. The disclosure further relates to a door having a hinge lock.

A system for use with an autonomous working machine such as a robotic lawn mower. The system may allow communication (directly or indirectly) between the machine and a gate or other barrier opening to allow unattended or remotely-controlled passage of the machine through the gate. In some embodiments, the mower may include a vision system operable to detect unknown objects within an area adjacent to the gate.

A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a keeper assembly including a magnet and a latch bolt assembly having: an elongated frame (32); a latch bolt (14) moveable between a latching position and a retracted position; a latch bolt biasing member urging the latch bolt into its retracted position; and a latch bolt operating mechanism configured to move the latch bolt from its latching position to its retracted position against a magnetic attraction. The latch bolt operating mechanism comprises: an effort link rod (37); a load link rod (34); and a second-order lever (35) interposed between the effort link rod and the load link rod. The second-order lever reduces the force required to operate the latch bolt operating mechanism thus allowing for an increased magnetic attraction of the latch bolt towards the magnet in the keeper assembly.

A door latch operator comprising: one of a knob and a lever on a door configured to articulate in response to a linear force, wherein the linear force is perpendicular to a central, longitudinal axis of a latch; a transmission configured to translate the linear force into a rotational motion; and a latch bolt configured to extend from the latch absent the rotational motion and retract into the latch upon reception of the rotational motion.

The present invention relates to a bidirectionally operating warfare lock mechanism (C) that prevents external interference (opening/unlocking) to hatches in military vehicles (A) during combat. The present invention particularly relates to a bidirectionally operating warfare lock mechanism (C) comprising a lock operating mechanism (100) that is connected to the vehicle (A) and that allows for opening and locking the hatch (B) when the user moves the lock lever (110) to P1 (161) and P2 (162) receptacles, and further comprising a lock bolt mechanism (200) that can be easily mounted by being rotated 180° around its axis without making any changes in the design, thereby allowing for being used in always-open or always-closed (locked) configurations according to the desired scenario.

A latch mechanism of a storage case where a case cover is openably and closably connected to a case body, the latch mechanism includes a latch arm connected to the case body and an arm receiving portion provided on the case cover. A hook is formed on a tip side of the latch arm. A locking claw is formed on a tip side of the arm receiving portion. The arm receiving portion is formed with an inclined surface that guides the hook toward a claw tip of the locking claw.

An interlock for an enclosure can include a primary interlock activator that translates a rod assembly upon movement of a primary door of the enclosure and a secondary interlock activator. The secondary interlock activator can be configured to be one of translated or rotated relative to the enclosure, by the rod assembly, to move a latch hook of the secondary interlock activator between engaged and disengaged positions. The secondary interlock activator can be configured to be placed in the engaged position by the translation of the rod assembly, when the primary door is closed, to prevent the secondary door from being opened. The primary interlock activator can be configured to be placed in the disengaged position by the translation of the rod assembly, when the primary door is open, to allow the secondary door to be opened.

A dock door assembly and a dock door assembly kit are provided for use in a dock door opening for installation in a warehouse. The dock door assembly comprises a pair of vertical tracks, with each vertical track configured to be attached to a wall along opposing lateral sides of the dock door opening. The dock door assembly also comprises a multiple, horizontal section door characterized by a vertical height when closed and mounted on the pair of vertical tracks. The dock door assembly further comprises a spring shaft assembly and a pair of headplates with each headplate having a U-shaped opening to receive each end of a torsion shaft. Further, the dock door assembly may comprise a pair of door cables and a pair of corner cable attachments connecting each door cable to the spring shaft assembly.

An improvement for use with a door latch assembly for a roll-up door includes a shim dimensioned and shaped to be positioned over a latch cover of the latch door assembly and to be slidingly moved to a shim extended position wherein a shim tang extends beyond a latch slide tang of the latch assembly. The shim is configured so that, if the latch assembly is mounted to a rolling door and is locked into an unsecured position by a first lock, wherein the slide tang does not engage the door jamb, the shim can be moved to and locked in the shim extended position to secure the rolling door without removing the first lock.
