  • Patent number: 6832499
    Abstract: The present invention discloses a vandal resistant coupled T-handle assembly for a T-handle locking assembly commonly used in vending machines. The coupled T-handle assembly comprises a hardened sleeve secured over a face element of the T-handle assembly. The hardened sleeve is formed from a tamper resistant, high strength material capable of resisting attempts by thieves and vandals to gain access to interior compartments of a vending machine by drilling through, battering or otherwise destroying the face element of the T-handle assembly and thereafter breaking the locking assembly. The T-handle assembly also includes additional lock holes at the base of the T-handle body to provide additional element passages for increased security.

  • Patent number: 5711506
    Abstract: A key-operated cylinder lock including a cylinder lock housing, a cylinder lock core assembly rotatably located within the housing, and an outwardly biased, radially movable lock bolt. The cylinder lock housing includes a cylindrical side wall encircling an axial cavity for receipt of the cylinder lock core assembly and a pair of opposed axially extending arcuate lugs extending inwardly from the cylindrical side wall into the axial cavity. The cylinder lock core assembly includes a core insert retaining several hardened key guides and biased tumblers. The core insert rotates within the cylinder lock housing to transfer force between a key inserted into a key entryway and an eccentric stud riding within a cam cavity defined within the lock bolt to effect radial movement of the lock bolt in conjunction with rotational movement of the key.

  • Patent number: 5636881
    Abstract: A latch housing defines an axial passage accessible at opposite ends thereof. Latch elements are radially displaced about the axis of the axial passage. A solenoid is mounted to an end of the latch housing and a post is inserted axially into the opposite end of the axial passage. The latch elements are biased to constrict around and preclude withdrawal of the post from the axial passage. An armature of the solenoid extends into the axial passage and a disengagement plate is attached to that end of the armature. As the post is inserted into the axial passage, a slot in the post mates with the disengagement plate, and the terminus of the slot contacts the disengagement plate causing the disengagement plate to translate along the axial passage with the post.

  • Patent number: 5467619
    Abstract: A latching system, in accordance with a first preferred, embodiment of the present invention, comprises a notched post assembly, a post gripping assembly and a handle assembly, and, in preferred embodiments, a lock assembly associated with the handle assembly. The notched post assembly is comprised of an elongated post formed at one end with at least two opposing, axially extending rows of notches or teeth and alternately disposed smooth surfaces. The post gripping assembly comprises a channel for accepting the notched end of the post and comprises movable latch elements which cooperate with the notches of the post to effect the primary latching function of the system. The unlatching of the post from the channel is accomplished by rotating the post to disengage the notches and the latch elements.
