Abstract

A quick release pin has an elongated body having an axial bore therethrough, a shaft extending at least partially through the axial bore for axial movement along the bore; a spindle separately mounted on a first end of the shaft; a button separately mounted on a second opposite end of the shaft; and a handle having a central passage through which the button extends, wherein the handle is mounted to the elongated body. The shaft can be interchanged with a variety of materials and lengths of shafts.

Claims

1. A quick release pin comprising:

an elongated body having an axial bore therethrough,

a flexible shaft extending at least partially through said axial bore for axial movement along said bore;

a spindle mounted on a first end of said shaft wherein said spindle and said shaft are separate components assembled together;

a button mounted on a second opposite end of said shaft,

a compression spring interposed between said button and said elongated body which engages said button to bias said button in a first axial direction; and

a handle having a central passage through which said button extends, wherein said handle is mounted to said elongated body, wherein said button comprises a flange, and said handle comprises a flange formed within said central passage configured to engage said flange of said button to restrict axial movement of said button.

2. The pin of claim 1, wherein said button comprises an indentation to be pressed by an end user.

3. The pin of claim 1, wherein said button is fixedly secured to said shaft.

4. The pin of claim 1, wherein said spindle comprises a recess which holds a pair of movable members.

5. The pin of claim 4, wherein said movable members move radially in lateral openings in said elongated body.

6. The pin of claim 5, wherein axial movement of said spindle brings said edge out of alignment with said movable members so said movable members move radially inwardly into openings of said elongated body.

7. The pin of claim 5, wherein axial movement of said spindle engage engages said movable members with a ramped edge of said spindle moving said movable members radially outwardly beyond an outer surface of said elongated body.

8. The pin of claim 1, wherein said spindle comprises a bearing surface to guide said spindle through said axial bore of said elongated body.

9. The pin of claim 1, wherein said button is depressed to move in a second axial direction;

wherein said first direction is opposite to said second direction.

10. The pin of claim 1, wherein said spindle and said button and said shaft are not integrally formed.

11. The pin of claim 1, wherein said shaft is flexible.

12. The pin of claim 1, wherein said shaft is guided by said axial bore of said elongated body.

13. The pin of claim 1, wherein said shaft is joined to said button via a locking bore formed in said shaft.

14. The pin of claim 1, wherein said shaft is joined to said spindle via a locking bore formed in said shaft.

15. The pin of claim 1, wherein said spindle is crimped to a said first end of said shaft.

16. A quick release pin comprising:

an elongated body having an axial bore therethrough,

a shaft extending at least partially through said axial bore for axial movement along said bore;

a spindle mounted on a first end of said shaft wherein said spindle and said shaft are separate components assembled together;

a button mounted on a second opposite end of said shaft; and

a handle having a central passage through which said button extends, wherein said handle is mounted to said elongated body;

wherein said shaft comprises wire rope.

17. The pin of claim 16, wherein said button is formed of aluminum.

18. The pin of claim 16, wherein said spindle is made of heat treatable steel.
