Quick detach shackle
A shackle is provided that is fixedly mounted to a surface. The shackle can have a body, a hasp, and a locking pin. The body can define at least one mounting bore that is configured for mounting the shackle to the surface. The proximal end of the hasp is configured to rotate relative to the body and the distal end of the hasp is configured to selectively engage the locking pin, such that an enclosed area is defined. A tethering device can be attached to the shackle via cooperative engagement with the selectively enclosed area.
1. A shackle for a helmet having a mounting surface comprising:
a body having a front surface, an opposing rear surface, a upper edge surface, an opposing lower edge surface, wherein the body defines a body locking pin bore extending from the upper edge surface to the lower edge surface, wherein the body defines at least one mounting bore extending from the front surface to the rear surface substantially transverse to the body locking pin bore, and wherein the body defines a recess extending from the lower edge surface towards the upper edge surface;
a locking pin configured for selective axial movement therein the body locking pin bore; and
a hasp having a distal end defining a hasp locking pin bore and comprising a shoulder member positioned at a proximal end of the hasp, wherein in a closed position, at least a portion of a proximal end of the locking pin extends from the body and through at least a portion of the hasp locking pin bore and at least a portion of the shoulder member of the hasp extends into the recess of the body, and wherein in an open position, the hasp is separable from the body,
wherein the at least one mounting bore is positioned therebetween the body locking pin bore and the hasp when the hasp is in the closed position.
2. The shackle of claim 1 , wherein the hasp has a central portion defining a cavity between an outer hasp wall and an inner hasp wall and further comprising a tethering device securedly attached to the cavity of the hasp.
3. The shackle of claim 2 , wherein an opening of the tethering device can enclose at least a portion of the outer hasp wall.
4. The shackle of claim 1 , wherein a distal end of the locking pin defines a bore configured to receive a pull ring.
5. The shackle of claim 1 , wherein a distal end of the locking pin defines a bore configured to receive a releasing lever.
6. The shackle of claim 1 , further comprising a bias element having a proximal end, and a distal end, wherein a portion of a proximal end of the bias element engage a portion of the body locking pin bore, and wherein a portion of a distal end of the bias element engages a portion of the locking pin.
7. The shackle of claim 6 , wherein in a first state, in which external force is not applied to the bias element, the bias element urges at least a portion of the proximal end of the locking pin to extend from the body.
8. The shackle of claim 7 , wherein in a second state, in which external force is applied to the bias element, at least a portion of the proximal end of the locking pin is contained therein the body locking pin bore.
9. The shackle of claim 1 , wherein the mounting surface is an exterior surface of a protective helmet.
10. The shackle of claim 1 , wherein the recess of the body comprises a plurality of walls.
11. The shackle of claim 10 , wherein at least one wall of the plurality of walls is positioned in a plane substantially parallel to an axis of the body locking pin bore.
12. The shackle of claim 11 , wherein at least one wall of the plurality of walls is positioned in a plane at an acute angle to the axis of the body locking pin bore.
13. The shackle of claim 1 , wherein the recess is positioned in a plane bisecting the at least one mounting bore.
14. The shackle of claim 1 , wherein at least a portion of the recess is arcuate and wherein at least a portion of the shoulder member is arcuate.
15. The shackle of claim 14 , wherein at least a portion of the arcuate recess is positioned around at least a portion of the at least one mounting bore.
16. The shackle of claim 1 , wherein the shoulder member is positioned in a plane substantially parallel to a longitudinal axis of the hasp locking pin bore.
17. The shackle of claim 1 , wherein the shoulder member is positioned in a plane at an acute angle relative to the longitudinal axis of the hasp locking pin bore.
