Abstract

A fastening pin, or peg is partially inserted into an aligned aperture and attached thereto by a webbed flashing. In a one-step assembly operation, the pin is driven further into the aperture as the flashing is broken and driven through an aligned aperture of a second component.

Claims

1. A fastening construction for securing items together, comprising:

a fastening pin, having a body with a nose at one end;

means for receiving said pin; and

frangible means supporting said pin axially aligned with and close to said receiving means;

wherein said frangible means is a flashing formed in molding said pin and said receiving means, and said frangible means is easily broken upon driving said pin further into said receiving means, and further wherein said means for receiving is a lug of a handle or lid, having an aperture formed therein.

2. The construction of claim 1, wherein said handle or lid is secured to a container by said fastening pin.

3. The construction of claim 1, wherein said frangible means joins said nose to a wall of said receiving means.

4. The construction of claim 1, further comprising means for securing said fastening pin in said receiving means after said frangible means has been broken and the pin has been driven further into said receiving means.

5. A fastening construction, as defined by claim 4, wherein said securing means comprises a shoulder, formed at the juncture of said nose and said body.

6. The construction of claim 5, wherein said pin includes an internal deformation slot in the area of said shoulder that permits said nose to fit through said aperture.

7. The construction of claim 1, wherein said pin and frangible means are formed from plastic.

8. The construction of claim 1, wherein said pin is initially partially within said receiving means.

9. A fastening construction for securing a handle to a container comprising:

a bullet shaped pin, having a flanged head portion, a conical nose and an elongate cylindrical body;

a pair of longitudinally aligned pivot legs, on an edge of said handle, each of said pivot legs having a longitudinally aligned aperture extending therethrough; and

a thin webbed flashing attaching and aligning said pin at least partially within one of said pivot legs, said flashing being adapted to be broken away when the pin is driven through said aperture.

10. A method of securing a handle to a container, comprising the steps of:

providing a handle having one or more pivot lugs disposed along an edge thereof, to mate with one or more lugs on the container, wherein one of said pivot lugs is provided with a fastening pin which is partially inserted or aligned to be inserted in one of said pivot lugs and attached thereto by a thin flashing;

aligning said pivot lugs of said handle with said container lugs; and

breaking the attachment of said flashing to said pin by forcing said fastening pin through said pivot lugs so as to secure said handle to said container.

11. The method of claim 10, wherein said pin has a nose and a body and shoulder at the junction of said nose and said body to hold said pin in position after the pin nose has been driven through said aperture and said breaking step includes driving said pin nose through said apertures.

12. The method of claim 11, wherein said pin includes an internal deformation slot in the area of said shoulder that permits said nose to fit through said aperture, and said breaking stp includes deforming said nose as it is driven through said aperture.
