1. A system for attaching a first object to a second object such that the first object can be quick released from the second object, comprising:

  • (a) a stepped bolt structure, comprising a shaft having an outer diameter, and a threaded stepped down portion having an outer diameter smaller than the outer diameter of the shaft, said stepped bolt structure further having a hole through the shaft along a non-parallel path with respect to an axis of the shaft;

    (b) a receiving structure for receiving the threaded stepped down portion of said stepped bolt structure;

    (c) a nut, having a thread corresponding to the thread on said sleeve, wherein the sleeve is configured to pass through a hole in the first object and engage with the nut, to thereby retain the first object;

    (d) a sleeve, having an inner diameter larger than the outer diameter of said shaft and being configured to pass over the shaft of the stepped bolt structure, said sleeve being threaded on at least a portion of an outer diameter thereof and having a hole corresponding to said hole in said shaft, and being configured to permit a in to extend through the hole in the sleeve, the hole in the spacer, and the hole in the shaft, said sleeve has a length and at least two different outer diameters, the largest of the two outer diameters being disposed on a first end having the hole in the sleeve and being larger than an inner diameter of said spacer;

    wherein a depth along said sleeve from a second end to a shoulder at a transition between the two different outer diameters is greater than the depth of said spacer;

    (e) a spacer, configured to be disposed between the first object and the second object, said spacer having a spacer hole having an inner diameter larger than the outer diameter of the sleeve and being configured to freely permit insertion of the sleeve over the shaft of the stepped bolt structure, and further having at least one hole cross-bored through the spacer hole corresponding to the spacer hole and the hole through the shaft of the stepped bolt structure; and

    (f) a pin, sized to be concurrently inserted through the cross-bored hole in the spacer, the hole in the shaft, and the corresponding hole in the sleeve;

    wherein;

    said receiving structure is disposed in the second object and the stepped bolt is connected thereto;

    said sleeve and said spacer are placed over the shaft of said stepped bolt and are connected together with said pin;

    the first object has a hole of sufficient diameter and disposed in position to allow the first object to be placed over the sleeve with clearance, said hole adapted to serve as an attachment point for the first object;

    the second object has a hole having a diameter larger than the outer diameter of the thread of the stepped down portion of said stepped bolt, and smaller than an outer dimension of said nut, to thereby retain the stepped bolt and said nut;

    the first object is placed through the sleeve and fastened in place with the nut, thereby being attached to the second object; and

    the pin is configured to be retained in the spacer, sleeve and the shaft when subject to tensile forces directly separating the first object and the second object, and the pin is configured to be readily extracted from the spacer, sleeve and the shaft to thereby quick-release the first object from the second object by application of a force along the axis of the shaft, to therefore separate the shaft and the sleeve.
