A panel fasteners (20) is disclosed in the form of a hook and cam assembly (21) having two side walls (24) with a boss (27) through which a cam shaft (28) is journalled. The cam shaft has a socket (29) and a round cam (30). A hook (32) is frictionally mounted in camming engagement with the cam. A leaf clutch spring (33) is mounted within a spring mounting notch (36) and in frictional engagement with a substantially round cam engagement hole (34) of the hook. To position the spring into the spring mounting notch and cam engagement hole the spring is pre-compressed prior to mounting it within the spring mounting notch by forcing it through a narrowing channel positioned adjacent the cam.

A railcar locking system that includes a railcar with a first radial door and second radial door. The first radial door includes a first keeper on the first radial door and a second keeper disposed above the first keeper on the first radial door. The second radial door includes a first hinge on the second radial door and a second hinge disposed above the first hinge on the second radial door. The second radial door further includes a locking rod that includes a first cam disposed at a first end of the locking rod and a second cam disposed at a second end of the locking rod. The first cam is configured to engage with a first lobe of the first keeper and the second cam is configured to engage with a second lobe of the second keeper when the locking rod is in the locked position.

Hardware for a lift glide door assembly and lift glide window assembly provides ease of opening with an operational opening assist that urges the door or window to an open position on operation of an opening handle. A lock mechanism actuates a lock pin, blocks opening gear mechanisms from operating and extends a security bolt for locking. A guide blade is provided for assisting the door during opening or closing operations.

A latch mechanism includes a handle connected to a pin by a linkage. The linkage converts rotation of the handle relative to a frame into axial movement of the pin between extended and retracted positions relative to the frame. The pin engages with a pre-load adjustment mechanism in the extended position to apply a pre-load through the linkage that biases the pin toward the extended position. The pre-load adjustment mechanism is adjustable to set the pre-load through the linkage to a predetermined value as selected by a user.

Fenestration systems and associated methods include use of a lock assembly having a housing, a cam gear, a reversal gear, and one or more catches. Various aspects relate to enhanced locking/security, including repeatability and overall efficacy.

A sliding door locking system includes a sliding door having an inner surface that slides over a doorway opening when the door is slidably mounted above the doorway opening, and an outer surface. A lock housing is mounted in the sliding door, the housing having an aperture extending through the inner surface of the sliding door. A latch is hingedly mounted in the aperture such that the latch is moveable from a retracted position, in which the door is slidable along the door opening, and an extended position, in which the latch engages a catch opposite the inner surface of the door and adjacent the doorway opening. At least one of the inner and outer surfaces of the sliding door includes an actuator that, when moved from a first position to a second position, moves the latch from the retracted position to the extended position.

A lock capable of locking a movable door includes a lock shell having opening parts, and hook tongues extending out of the opening parts. The lock further includes lock tongue support frames, lock tongue reset springs, left and right first guide grooves, and shifting blocks. The lock tongue support frames are movably disposed on the lock shell and combined with shaft pins. The hook tongues have lower shaft holes and rotatably sleeve the shaft pins via the lower shaft holes. Each lock tongue reset springs has one free end combined with the lock tongue support frames, and another one free end combined with the hook tongues. The left and right first guide grooves are symmetrically-arranged and correspond to the shaft pins. Two ends of the shaft pins respectively extending into the left and right first guide grooves. The shaft pins drive the hook tongues to move to be unhooked or locked when the lock tongue support frames move to drive the shaft pins to move along the left and right first guide grooves. Axial centers of the shifting blocks have center holes that allow shifting sheets to be inserted therein. The lock tongue support frames are able to move back and forth to respond to rotation of shifting handles on the shifting blocks when the shifting blocks rotate.

A latch mechanism includes a handle connected to a pin by a linkage. The linkage converts rotation of the handle relative to a frame into axial movement of the pin between extended and retracted positions relative to the frame.
