The present invention relates generally to high security padlocks and particularly to a high security padlock with lockable hasp assembly.
Many high security padlocks are commercially available. For example, Mul-T-Lock Ltd. produces C-Series Padlocks that include a single pin, for general use with commercially available hasps or heavy duty chains which accept 13 mm pins.
Padlocks that have protected hasps are also known. For example, U.S. Pat. No. 4,548,058 to Bahry and Dolev describes a padlock assembly in which each side of a door opening, e.g., a hinged door and a jamb, or two sliding doors, is provided with a protective hasp for a lock body and shackle of a lock. Each half of the hasp is so formed that, when mated, as on joining of the doors or closing of the doors, provisions are made for insertion of a lock body into the protective hasp, and insertion of a shackle through the hasp and the lock body to lock the closure. More specifically, the padlock assembly includes two complementary shells, which when abutting each other, enclose the entire padlock. Each shell has an opening from the top for the insertion of one leg of the shackle, and a larger opening from the bottom to house the lock body when the shells abut against each other. The shells provide the attachment means for the padlock on the door and jamb.
The present invention seeks to provide an improved padlock including a hasp assembly with a locking mechanism, having members that are lockable together, as described more in detail hereinbelow.
It is noted that the term “door” as used throughout the specification and claims encompasses any kind of door, window, gate or panel, for example.
There is thus provided in accordance with an embodiment of the present invention a padlock hasp assembly including a first hasp member and a second hasp member including interface contours including complimentary shaped protrusions and recesses that mate with one another, and a locking assembly housed in the first hasp member, the locking assembly including a cylinder lock including a tumbler adapted to bring a locking element into locking engagement with a notch formed in a locking bolt, the locking bolt being arranged for sliding motion through a first bore formed in the first hasp member, and when the second hasp member is aligned with the first hasp member, the locking bolt is slidable into a second bore formed in the second hasp member so as to lock the first and second hasp members together. The locking element may be movable into locking engagement with a second notch formed in the locking bolt so as to prevent moving the locking bolt completely out of the first hasp member.
The present invention will be understood and appreciated more fully from the following detailed description taken in conjunction with the drawings in which:
Reference is now made to
Padlock hasp assembly 10 may include a first hasp member 12 and a second hasp member 14. The first hasp member 12 may house a locking assembly that includes a locking bolt 16 that may pass through a portion of second hasp member 14 so as to lock the two hasp members together. The hasp members 12 and 14 and locking bolt 16 may be constructed of any suitable material, such as but not limited to, hardened steel alloy. Locking bolt 16 may include a head 15 that may have a narrow neck portion for shearing off upon attempted tampering therewith.
The locking assembly may include a cylinder lock 18, such as but not limited to, a Mul-T-Lock high precision telescopic pin tumbler system, which may be pick and drill resistant for high security needs. As is well known in the art, cylinder lock 18 may include a tumbler or plug 20 which may be rotated by means of an authorized key (not shown) inserted in the keyway 21 (
When locking element 26 is moved away from locking element 26 and out of locking engagement with first notch 24, locking bolt 16 may be slid in the direction outwards of first hasp member 12. As long as the portion of shank 22 between first and second notches 24 and 25 slides past locking element 26, the thickness of the shank 22 prevents locking element 26 from moving back inwards. When the second notch 25 moves in alignment with locking element 26, the smaller diameter of second notch 25 permits locking element 26 to move back inwards, thereby locking against second notch 25. This prevents locking bolt 16 from being pulled completely out of first hasp member 12.
The first and second hasp members 12 and 14 may have interface contours including complimentary shaped protrusions and recesses that mate with one another. By “mating with another” it is meant that when the hasp members 12 and 14 are mounted on each side of a door opening, e.g., a hinged door and a jamb, or two sliding doors, the interface contours can mesh together without interference when closing the doors (the locking bolt 16 being in an unlocked position wherein it juts out of first bore 28 and does not interfere with the second hasp member 14), no matter whether the doors are sliding or hinged doors.
The interface contour of first hasp member 12 may include a first straight surface 31 (vertical in the sense of
Similarly, the interface contour of second hasp member 14 may include a first straight surface 41 (vertical in the sense of
Surfaces 44, 45 and 46 define a tongue 40 that mates with a recess defined by surfaces 34, 35 and 36. As mentioned above, locking bolt 16 may pass through second bore 30 formed in second hasp member 14, and second bore 30 passes through tongue 40.

It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the features described hereinabove as well as modifications and variations thereof which would occur to a person of skill in the art upon reading the foregoing description and which are not in the prior art.
