Abstract

A fastener assembly includes an elongated fastener body with a head end part. A propelling member supported on the fastener body, wherein the propelling member has a lengthened shape, wherein a portion of the lengthened shape extends around the head end part of the fastener body. A method of propelling the fastener assembly is also provided.

First claim

The invention claimed is:

1. A fastener assembly, comprising:
a fastener body with an entry tip at a first end and an enlarged head part at a second end, and a shank extending between the first end and the second end and a longitudinal axis running between the first end and the second end;
a propelling member engaged with and carried on the fastener body and configured for being translated jointly with the fastener body out of an orifice of a propelling tool by an externally applied propulsion force that is applied by the propelling tool onto an external cylindrical surface of the propelling member, wherein the propelling member has a lengthened shape, wherein a portion of the lengthened shape extends around the head part, wherein the head part and a first portion of the shank are embedded in the propelling member such that both a side of the head part and an end face of the head part are surrounded and covered by the propelling member, the end face being covered by the propelling member as seen in a direction along the longitudinal axis and toward the end face, wherein a second portion of the shank extends axially beyond an end edge of the propelling member to expose the second portion of the shank and the entry tip externally of the propelling member such that the end edge of the propelling member is positioned axially between the first end and the second end of the fastener body, wherein the propelling member is configured to distort as the fastener body is set into a support and to separate from the fastener body and the support upon complete setting of the fastener body into the support.

2. The fastener assembly according to claim 1 , wherein the propelling member is configured so as to be at least partially dissociated from the fastener body upon a laying of the fastener body into a support.

3. The fastener assembly according to claim 1 , wherein the propelling member is made of a first material and the fastener body is made of a second material, wherein the first material is less hard than the second material.

4. The fastener assembly according to claim 1 , wherein the propelling member includes at least one weakening longitudinal side slot configured to facilitate dissociation of the propelling member from the fastener body upon a setting of the fastener body into a support.

5. The fastener assembly according to claim 1 , wherein the fastener body is formed as a nail and the propelling member presents, in section, a cylindrical or parallelepiped lengthened shape, wherein an extension axis of the propelling member and a longitudinal axis of the nail are juxtaposed.

6. The fastener assembly of claim 1 , wherein the fastener body is formed as a nail and the propelling member presents, in section, a cylindrical or parallelepiped lengthened shape having a transversal dimension or diameter that is larger than a diameter of the head part.

7. A fastener assembly, comprising:
an elongated fastener with a head end part and an entry tip end part and a longitudinal axis;
a propelling member engaged with and carried on the fastener and configured for being translated jointly with the fastener out of an orifice of a propelling tool by an externally applied propulsion force that is applied by the propelling tool onto an external lateral surface of the propelling member, wherein the propelling member has a lengthened shape, wherein a portion of the lengthened shape extends around the head end part of the fastener to cover an axial end of the head end part as seen in direction along the longitudinal axis and toward the head end part,
wherein the propelling member includes at least one weakening longitudinal side slot configured to facilitate at least partial dissociation of the propelling member from the fastener upon the laying of the fastener into a support;
wherein the propelling member is made of a first material and the fastener is made of a second material, wherein the first material is less hard than the second material, and
wherein the head end part of the fastener is embedded into the propelling member and the entry tip end part extends axially beyond an axial end of the lengthened shape of the propelling member such that the axial end of the lengthened shape of the propelling member is located axially between the head end part and the entry tip end part,
wherein the propelling member is configured to distort as the fastener is set into a support and to separate from the fastener and the support upon complete setting of the fastener into the support.

8. A method for setting a fastener into a support, the method comprising:
using an indirect firing fastening tool having first and second driving wheels,
wherein the fastener is formed as part of a fastener assembly that includes a propelling member engaged with and carried on the fastener for transferring an externally applied propulsion force to the fastener, wherein the fastener has a longitudinal axis and spaced apart axial ends, wherein the propelling member has a lengthened shape with spaced apart axial ends, wherein an axial length of the propelling member overlaps with part of an axial length of the fastener such that one axial end of the propelling member is located between the spaced apart axial ends of the fastener, and
driving the fastener assembly in translation from the tool by the first and second driving wheels directly engaging an external surface of the propelling member between the axial ends of the propelling member to apply a propulsion force to propel both the propelling member and the fastener out of an orifice of the tool such that the fastener is set into the support, wherein the propelling member distorts as the fastener is set into the support and separates from the fastener and the support upon complete setting of the fastener into the support.

9. The method of claim 8 wherein the driving wheels compress the propelling member as the propulsion force is applied.
