Fastener

Claim 2

A fastener assembly which can be secured to an object and used in combination with anchor means secured to another object for securing the two objects together comprising: a fastener in the form of an open-ended loop which forms a bore with the opposite ends of said loop forming at least one arm which extends from the loop and is curved to form a hook, an integrally formed projection within said bore whose opposite edges form a pair of stops; an eccentric member disposed within said bore formed by said loop and having a reduced diameter portion which extends about substantially one-half of its circumference and forms a pair of stops which are engageable with said stops on said fastener, the engagement of respective pairs of said stops preventing further rotation of said eccentric member within said bore; said bore being slightly smaller in diameter than said eccentric member so that the peripheral edges thereof frictionally grip the circumference of said eccentric member, and means retaining said fastener and said eccentric in operable assembled relation, whereby rotating said eccentric member will cause said fastener to rotate to engage said hook with said anchor means, further rotation of said eccentric member rotating said eccentric member within said bore such as to stretch said hook engaged with said anchor means, the stretching of said hook increasing the spring load capacity of said fastener and maintaining tight frictional hold on said eccentric member, and said hook being releasably disengaged from said anchor means by reversing the rotation of said eccentric member.

Claim 3

The fastener assembly of claim 1, wherein said fastener is stamped from sheet material.

Claim 4

The fastener assembly of claim 2, wherein said eccentric member is formed from two circular-shaped pieces which are stamped from sheet material and affixed together, each of said pieces having a stamped extrusion provided off-center thereof with a keyed bore therein for receiving a key member for rotating the eccentric member.

Claim 5

A fastener assembly which can be secured to an object and used in combination with anchor means secured to another object for securing the two objects together comprising: a fastener in the form of an open-ended loop which forms a bore with the opposite ends of said loop forming a pair of arms which extend substantially concentrically with one another and are curved to form a pair of hooks, an integrally formed projection within said bore whose opposite edges form a pair of stops; an eccentric member disposed within said bore formed by said loop and having a reduced diameter portion which extends about substantially one-half of its circumference and forms a pair of stops which are engageable with said stops on said fastener, the engagement of respective pairs of said stops preventing further rotation of said eccentric member within said bore; said bore being slightly smaller in diameter than said eccentric member so that the peripheral edges thereof frictionally grip the circumference of said eccentric member, and means retaining said fastener and said eccentric in operable assembled relation whereby rotating said eccentric member will cause said fastener to rotate to engage said hook with said anchor means, further rotation of said eccentric member rotating said eccentric member within said bore such as to stretch said hook engaged with said anchor means, the stretching of said hook increasing the spring load capacity of said fastener and maintaining tight frictional hold on said eccentric member, and said hook being releasably disengaged from said anchor means by reversing the rotation of said eccentric member.

Claim 6

A fastener assembly which can be secured to an object and used in combination with anchor means secured to another object for securing the two objects together comprising: a fastener in the form of an open-ended loop which forms a bore with the opposite ends of said loop forming a pair of arms which extend substantially concentrically with one another and are curved to form a pair of hooks, an integrally formed projection within said bore whose opposite edges form a pair of stops; an eccentric member disposed within said bore formed by said loop and having a reduced diameter portion which extends about substantially one-half of its circumference and forms a pair of stops which are engageable with said stops on said fastener, the engagement of respective pairs of said stops preventing further rotation of said eccentric member within said bore; said bore being slightly smaller in diameter than said eccentric member so that the peripheral edges thereof frictionally grip the circumference of said eccentric member, and means retaining said fastener and said eccentric in operable assembled relation whereby rotating said eccentric member will cause said fastener to rotate to engage said hook with said anchor means, further rotation of said eccentric member rotating said eccentric member within said bore such as to stretch said hook engaged with said anchor means, the stretching of said hook increasing the spring load capacity of said fastener and maintaining tight frictional hold on said eccentric member, and said hook being releasably disengaged from said anchor means by reversing the rotation of said eccentric member.

Claim 7

The fastener assembly of claim 4, wherein said fastener is stamped from sheet material.

Claim 8

The fastener assembly of claim 5, wherein said eccentric member is formed from two circular-shaped pieces which are stamped from sheet material and affixed together, each of said pieces having a stamped extrusion provided off-center thereof with a keyed bore therein for receiving a key member for rotating the eccentric member.
