Abstract

The invention is related to construction, namely, discloses a shackle and a locking device comprising said shackle. The technical effect is improving the performance of the device due to a certain design of the shackle. The technical effect is achieved by the fact that the shackle comprises: a first end; a second end, and a plurality of bends between the first end and the second end, thereby forming: a first segment between the first end and a first bend, a second segment between the first bend and a second bend, a third segment between the second bend and a third bend, and a fourth segment between the third bend and the second end, wherein the first segment lies in a first plane and the fourth segment is substantially co-planar with the first segment, and the technical effect is also achieved by design options of the locking device comprising said shackle.

Claims (32)

1. A shackle comprising:

a first end;

a second end; and

a plurality of bends between the first end and the second end, thereby forming:

a first segment between the first end and a first bend, the first segment including an arcuate portion adjacent the first bend;

a second segment comprising an entirety of the shackle between the first bend and a second bend;

a third segment comprising an entirety of the shackle between the second bend and a third bend; and

a fourth segment between the third bend and the second end, the fourth segment including an arcuate portion adjacent the third bend,

wherein the first segment lies in a first plane and the fourth segment is substantially co-planar with the first segment, the second segment lies in a second plane substantially perpendicular to the first plane and the third segment is substantially co-planar with the second segment, and the second segment is disposed more distally from both the first end and the second end than is the third segment.

2. A locking device comprising:

a lock body;

a locking mechanism within the lock body; and

a shackle having:

a first end;

a second end;

a plurality of bends between the first end and the second end, thereby forming:

a first segment between the first end and a first bend, the first segment including an arcuate portion adjacent the first bend;

a second segment comprising an entirety of the shackle between the first bend and a second bend;

a third segment comprising an entirety of the shackle between the second bend and a third bend; and

a fourth segment between the third bend and the second end, the fourth segment including an arcuate portion adjacent the third bend,

wherein the first segment lies in a first plane and the fourth segment is substantially co-planar with the first segment, the second segment lies in a second plane substantially perpendicular to the first plane and the third segment is substantially co-planar with the second segment, and the second segment is disposed more distally from both the first end and the second end than is the third segment, and

wherein at least one of the first end and the second end of the shackle is alternately removable from the lock body and securable within the lock body by the locking mechanism.

3. The locking device of claim 2 , further comprising:

a placard affixed to a surface of the lock body.

4. The locking device of claim 3 , wherein the placard is affixed to the lock body with an adhesive, a screw, or both.

5. The locking device of claim 3 , wherein the placard is welded to the lock body.

6. The locking device of claim 3 , wherein the placard is affixed to the lock body with one or more magnets.

7. The locking device of claim 3 , wherein the placard includes at least one hole extending from a surface affixed to the lock body to an opposite surface.

8. The locking device of claim 7 , further comprising a plug device, a portion of which is sized to pass through the at least one hole.

9. The locking device of claim 8 , wherein the plug device comprises:

a head; and

at least one deformable barbed member.
