Abstract
The lock construction of the present invention has a lock body defining an interior cavity and a shackle that is releasably received in the interior cavity. The shackle is movable to a locked position for securing to an object and an unlocked position for releasing the object between the shackle and the lock body. A locking mechanism is disposed within the interior cavity of the lock and comprises rotatable first and second members. A motor is included to rotate said second member and thereby rotate the first member to secure and release the shackle between the locked and unlocked positions.
Claims41
A lock construction, comprising:
- a) a lock body defining all interior cavity;
- b) a shackle connected to said lock body and movable to a locked position for securing to an object between said shackle and lock body and an unlocked position for releasing said object secured therebetween;
- c) a lock mechanism disposed within the interior cavity, including:
- i) a rotatable first member having it toothed section and operatively connected to said shackle for rotation between a first position, to secure said shackle in said locked position in said lock body, and a second position, to release said shackle for movement to said unlocked position, and
- ii) a rotatable second member disposed adjacent to said first member and having a threaded section configured to intermesh and rotate with said toothed section of said first member, wherein said second member is rotated in a first direction to engage the lock mechanism and in a second direction to disengage the lock mechanism;
- and
- d) a motor for rotating said second member and thereby rotates said first member between said first and second positions to respectively secure and release said shackle.
