Abstract: A locking system for closing and locking a lid on an enclosure such as a grade level enclosure. The locking system includes a latch formed on an edge of a lid of the enclosure. The latch includes a bolt recess on an upper face of the lid which opens into a slotted wall structure that forms a passage below the lid. The bolt recess has a slotted opening which receives an L-bolt that extends down into a hollow interior of the slotted wall structure. A right angle leg on the L-bolt protrudes below the slotted wall structure when a fastener head atop the L-bolt rests in the bolt recess. The fastener head of the bolt in its at-rest position in the bolt recess provides access for rotating the L-bolt (and its right angle leg) with a tool that fits into the bolt recess to engage the fastener head. The bottom leg of the L-bolt, when rotated to its locked position, protrudes under a locking surface inside the enclosure. This releasably locks the lid to the enclosure.

Abstract: A circuit board retaining assembly for coupling a component to a chassis without concern for the loss of mounting hardware, such as for coupling computer hardware to a computer chassis, and for doing so particularly when the component is in operation. The retaining assembly includes a mounting bracket for mounting the assembly to the chassis, a lever extending from the mounting bracket, and a lever biasing member for pivotally biasing the lever away from the chassis when the component is installed in or removed from the chassis. The mounting bracket includes at least one lever opening for receiving the lever. The lever includes a first end for releasably coupling the component to the chassis. The lever-biasing member is disposed between the mounting bracket and the lever to bias the lever away from the chassis when it is disengaged from the chassis.

Abstract: An electrical transformer having an integral cabinet with an apparatus for latching and locking the doors of the cabinet. The apparatus is comprised of a three point latch system. The first and second latch points are vertical latch rods which engage sills in the cabinet. The third latch point is a latch plate which rotates with a shaft extending through the first door and to which a handle is attached. In the secured position, the latch plate rotates behind a flange extending from an interior wall, thereby preventing the door from being pulled open. The internal wall divides the cabinet into low and high voltage compartments and forms a structural portion of the cabinet. A bolt extends through the first door, the second door, the latch plate and the flange, thereby preventing the doors from being pulled open and preventing rotation of the handle. A cylinder attached to the first door surrounds the head of the bolt and prevents access thereto.

The handle unit consists of the fixed seat attached to the door, a movable body connected to the fixed seat by a pivot, a latch member, and an operating handle for driving the latch member. The door handle device also has a setting bolt, an operating portion is positioned in the inside of the refrigerator. The setting bolt is inserted into a threaded bore provided in a rear portion of the movable body to fix the movable body to the door. The trapped person has only to turn the operating portion of the setting bolt to take out the bolt from the threaded bore and thereby permit the movable body to pivot and release the latch member from the latch receiver unit and then open the door.

Abstract: This invention relates to a rotary type latch for sliding screen doors wherein the rotary member is molded from a plastic material such as a polycarbonate and which is rotatable in either direction for universal application to either right hand or left hand door operations. The rotary latch engages a slot in a door pull molded from a similar plastic material and contacts the screen door frame through the slot to cam the door against a retaining channel mounted on a door frame. The rotary latch includes a plurality of flat cam faces affording multiple locking positions and which necessitate positive lock rotation to enable the latch to be disengaged. This latch mechanism is of particular usefulness for application to sliding patio screen doors where the screen door closes into a pocket within the side jamb of the patio door frame.

Abstract: A door security latch is disclosed including a link member pivotably attached to the door frame on the inside of the door and which is swingable to a position overlapping the inside face of the door. The link carries a threaded stop having a door face engageable portion which can be screwed into abutment with the door face.

Abstract: A firm closure and locking device to firmly close and lock a vent window pivotally mounted and adjacent to a rigid member. The device has a body portion configured in a U-shape which fits over the edge of the vent window adjacent to the rigid member. A locking arm is pivotally mounted to the body onto a pivot element, preferably a screw-like member projecting from the body. A pressure-bearing device, such as a handle with an internal threaded receptacle portion is threadedly engaged onto the screw-like member. The handle is rotated upon the screw-like member to advance it inwards towards the body, thereby applying pressure against the locking arm intermediate the handle and the body of the locking device. When the U-shaped portion of the body is fitted over the edge of the vent window adjacent the rigid member and no pressure is applied against the locking arm, the locking arm is free to rotate about the screw-like member until it abuts against the side of the adjacent rigid member.

Abstract: A door and handle latch for apparatus enclosures includes a recessed handle latch on the door which serves to immovably secure the door to the enclosure structure by engaging a portion of the enclosure when the handle latch is in the closed position. A bolt means is provided in the lower portion of the handle latch to secure the handle latch to the door in a closed position, thus, preventing opening of the enclosure.
