Abstract: A puck shaped lock including a substantially cylindrical body into which a cavity is formed and a movable bolt that passes through the cavity and is shiftable from a first position advanced across the cavity to a second position substantially withdrawn from the cavity and which can be releasably secured across the cavity fixedly connected to and extending from the puck shaped lock and being securable to a door or a door jamb. The invention further includes a hasp member supporting a first staple securable to a door or a doorjamb. When the puck shaped lock is positioned overlying the hasp member the staple is inserted into the cavity and the movable bolt can be advanced across the cavity and through the opening in the staple whereby the puck shaped lock and the hasp member are secured together and the door is locked.

Abstract: A gate latch including a bolt portion, a sleeve portion and a channel bolt. The sleeve portion is mounted on a generally U-shaped clamp assembly that is adapted to fit around tubular gate members. The sleeve portion further includes a receiving notch and a padlock portion. The padlock portion is adapted to receive a standard padlock and to surround the shackle of the padlock so as to deter attempts to attack the shackle with cutting tools. The bolt portion includes a C-shaped channel adapted to be secured around tubular gate members and a sleeve in which the channel bolt slides. The channel bolt generally includes an elongate channel, an adjustable stop, a dead stop, a handle and a locking notch.

Abstract: A kingpin lock device generally including a lock housing, a selectively engageable lock, and a sliding member. The lock housing can include a kingpin receiving aperture, a lock receiving channel, and a sliding channel. The sliding member can include a concave portion at one end for engaging the surface of the kingpin, a slot portion intermediate the sliding member for receiving the selectively engageable lock, and a stop lip/flange portion at the end distal the curved portion. The stop flange portion includes at least one lip for engaging the outer surface of the lock housing upon positioning of the sliding member within the sliding channel. As such, movement of the sliding member within the sliding channel is limited and the introduction of a substantial longitudinal force on the sliding member will not bring the lock into damaging forceable contact with the slot portion of the sliding member.
