(57) ABSTRACT
The present lock construction, for securing a movable object to a fixed object, includes a housing having an interior cavity and an elongated member having a first portion secured within the housing and a second portion slidably received within the housing. The elongated member is slidable within the passageway to a locked position, securing the movable object to the fixed position and to an unlocked position, releasing the object from the fixed object. First and second members are slidably disposed in the housing and are movable to engage the cable in the locked position. A rotatable locking mechanism is disposed within said housing and is engageable with the first member to permit slidable movement of the first member and thereby allow slidable movement of the elongated member to different locked positions. The rotatable locking mechanism is also engageable with the second member to permit slidable movement of the second member and thereby prevent movement of said elongated member in the locked position.
