Abstract: An electrical connection mount system has an electrical connection mount and a controlled locking mechanism configured to lock/unlock a complementary electrical connection mount connected with the electrical connection mount. The locking mechanism includes at least one first lever and one second lever, and an electromagnet. The first lever forms a latch which is movable between a locking position and an unlocking position. The second lever is mechanically coupled to the electromagnet and cooperates with the first lever. Actuation of the electromagnet allows moving the first lever from the locking position to the unlocking position.

Abstract: A punch for punching a sheet of material, the punch having a body formed with a fissure for receiving the sheet of material, a pivot shaft defining a pivot point, and a lever pivotably mounted about said pivot shaft has an open position and a closed position. A block is provided which is positionable between the lever and the body. The body is provided with longitudinal support ridges and the lever is provided with side ridges, with the pivot point positioned in substantially the same plane as the longitudinal support ridge so that when the punch is closed, the side ridges of the lever pass outside of the support ridges of the body in a nesting relationship, allowing the punch to form a flat profile when closed.

Abstract: A latch mechanism for releasably securing a hinged gate to one or more latches. The latch mechanism includes a handle that is pivotally connected to a gate wall. The handle includes at least one retention arm that lockingly engages a latch when the hinged gate is in a latched position. According to certain embodiments, the handle includes a retention arm at both ends of the handle, with the handle extending generally along the length of the gate wall. Further, the handle may be pivotally displaced about the retention arm(s) so that the handle is displaced from the first position to a second position. As the handle is pivotally displaced to the second position, a release mechanism of the handle may engage and pivotally displace the adjacent latch so that the retention arm may be released from the locking engagement with the latch.

Abstract: An anti-ligature handle and escutcheon for operating a lock. The handle and escutcheon are smoothly curved in all directions to eliminate hanging points and prevent suicide by preventing the attachment of a ligature to the handle or escutcheon. The handle is curved to allow fingers to be inserted behind the handle to pull on the handle. The handle is attached to a handle plate that slides behind an escutcheon plate portion of the escutcheon. Multiple ligature traps in the form of an inverted “V” are positioned in parallel offset rows between the handle plate and the escutcheon plate to prevent the insertion of a ligature around the handle and handle plate.

Abstract: A latch system includes a catch member and a sear element engaged with the catch member when the catch member is in a latch position. A swing lever is in geared engagement with the sear element. When the latch system is subjected to an acceleration event, the swing lever pivots in one direction so that the sear element pivots in the opposite direction to move the sear element out of engagement with the catch member. The latch system may further include a security mechanism that is configured to prevent the swing lever and sear element from moving in response to an acceleration event under the condition the latch system is not oriented in an upright and vertical orientation. When the latch system is returned to its upright position, the security mechanism may be configured to not interfere with the normal operation of the latch system.

Abstract: A multi-position latch mechanism is provided for a subsurface aircraft ground servicing chamber formed by a pit having an upright interior wall and a pit lid seat disposed atop the pit. A pit lid is provided which, when closed, rests upon the pit lid seat. The latch mechanism includes a catch member depending from the pit lid adjacent the upright wall of the pit. The catch member is mounted to the pit lid for rotatable movement relative thereto. A latching member is mounted on the upright interior pit wall and has a plurality of vertically spaced teeth that face the catch member. The catch member has a hook facing the latching member. The hook is alternatively engageable with each of the teeth, depending upon the extent to which debris on the pit lid seat holds the pit lid off of its pit lid seat.

Abstract: A latch assembly for a trailer roll up door has a base plate, a handle and hook assembly with a locking flange rotatably mounted to the base plate, a closed keeper to selectively retain the handle in the closed position. The closed keeper is moveably mounted to the base plate for movement between a latched position and an unlatched position. The movement of the closed keeper is limited by stops on the base plate and further has a rotation stop that is adapted to contact a portion of the handle when the closed keeper is in the unlatched position and the handle is moved to the closed position to move the closed keeper into the latched position.

Abstract: A cover member for room partitions having a frame with at least one slotted cross-member. The cover member includes a pivoting lock member having a protruding lock tab shaped for reception in a slot in a slotted cross-member of a frame. A connecting member rotatably connects the lock member to a surface of the cover member in a manner which permits the lock member to be rotated about a center of rotation between an insertion position wherein the lock tab is in registry with the cross-member slot and an engaged position wherein the lock tab is engaged with the cross-member to positively yet removably lock the cover member on the frame. The lock member is set up such that the lock tab has a smaller lateral displacement from the center of rotation of the pivoting lock member in the engaged position than in the insertion position. At least one frictional member is configured to be connected to the cover member and extend through the pivoting lock member to frictionally hold the pivoting lock member in position.

Abstract: Locking latch device for use with roll-up doors on trucks and tractor-trailer vehicles which will automatically latch when closing the door and which can only be opened after a pendulous latch member is set to an unlatching position by the use of a release member. A locking device is provided to render the latching mechanism inoperable to prevent unauthorized opening of the roll-up door.

Abstract: Pilferage deterrent device for box car, container or trailer doors of the type in which the device is toward the top of the door out of reach of a person standing on the ground, and only accessible to release the latch from the top, by a person standing on a loading dock or elevated platform. The latch cooperates with a keeper and both the keeper and latch are enclosed so access cannot be had to the latch to release the latch by a pole or elongated tool.A pivoted release member termed a trigger extends above a housing for the latch and is transversely pivoted to the housing and protected by the housing to prevent access to said release member from the ground. The release member has camming engagement with the latch and is operable by hand to cam the latch out of engagement with the keeper and accommodate opening of the door.

Abstract: There is disclosed a self-adjusting latch for an overhead truck door comprising a latch bolt, a keeper, and a bolt catch all pivotally mounted at predetermined locations on a common support plate. The latch bolt has an integral actuating arm and an integral hook for latching engagement with a catch pin mounted in the bed of the truck. The weight of the latch bolt is distributed in such a manner that after latching, the latch bolt is continuously urged against the catch pin. Thus the latch is continuously self-adjusting during normal operation of the truck over rough or uneven terrain. The keeper is rotatable from a locked to an unlocked position, and when it is in the locked position it prevents unlatching of the latch bolt by abutting engagement thereagainst. When the truck is in transit, the keeper is maintained in the locked position by locking a finger thereon against a lug struck out from the support plate.
