Abstract

A method of securing a first component part and a second component part together, the method comprising providing an electrically conductive member between a first surface of the first component part and a facing first surface of the second component part and securing the first and second components together by passing a current through the electrically conductive member. The electrically conductive member may comprise a first portion connectable to a source of current and a second portion electrically connected to the first portion and comprising a plurality of sub-conductive members. The electrically conductive member may be distributed across at least 50% of the surface area of the first surface of the first component part.

First claim

1 . A method of securing a first component part and a second component part together, the method comprising:
(a) providing an electrically conductive member between a first surface of the first component part and a facing first surface of the second component part wherein the electrically conductive member comprises a first portion connectable to a source of current and a second portion electrically connected to the first portion and comprising a plurality of sub-conductive members; and, (b) securing the first and second components together by passing a current through the electrically conductive member.

2 . The method of claim 1 wherein the first face of the first component has a surface area that is to be connected to the first face of the second component and the plurality of sub-conductive members are distributed across at least 50% of the surface area.

3 . The method of claim 1 wherein the first face of the first component has a surface area that is to be connected to the first face of the second component and the plurality of sub-conductive members are distributed across at least 75% of the surface area.

4 . The method of claim 1 wherein the sub-conductive members are generally evenly spaced apart from each other.

5 . The method of claim 1 wherein the first portion of the electrically conductive member and each of the sub-conductive members has a longitudinal length and a width ire a direction transverse to the length and the width of each of the sub-conductive members is narrower than the width of the first portion of the electrically conductive member.

6 . The method of claim 1 wherein step (a) comprises providing the electrically conductive member on a substrate and placing the substrate between the first surface of the first component part and the facing first surface of the second component.

7 . The method of claim 1 wherein the substrate is a meltable substrate at a temperature which is achieved when step (b) is conducted.

8 . The method of claim 1 wherein at least the first component part is not melted at a temperature which is achieved when step (b) is conducted.

9 . The method of claim 8 wherein at least the first component part comprises wood.

10 . A substrate having an electrically conductive member provided thereon wherein the electrically conductive member comprises a first portion connectable to a source of current and a second portion electrically connected to the first portion and comprising a plurality of sub-conductive members.

11 . The substrate of claim 10 wherein a face of the substrate on which the electrically conductive member is provided has a surface area and the sub-conductive members are distributed across at least 50% of the surface area.

12 . The substrate of claim 10 wherein a face of the substrate on which the electrically conductive member is provided has a surface area and the sub-conductive members are distributed across at least 75% of the surface area.

13 . The substrate of claim 10 wherein the sub-conductive members are generally evenly spaced apart from each other.

14 . The substrate of claim 10 wherein the first portion of the electrically conductive member and each of the sub-conductive members has a longitudinal length and a width in a direction transverse to the length and the width of each of the sub-conductive members is narrower than the width of the first portion of the electrically conductive member.

15 . A manufactured part comprising first and second component parts that are secured, together, the manufactured part comprising an electrically conductive member positioned at an interface of the first and second component parts, wherein the electrically conductive member comprises a first lead portion and a plurality of sub-conductive members each of which extends from the lead first portion.

16 . The manufactured part of claim 15 wherein the interface of the first and second parts has a surface area and the sub-conductive members are distributed across at least 50% of the surface area.

17 . The manufactured part of claim 15 wherein the interface of the first and second parts has a surface area and the sub-conductive members are distributed across at least 75% of the surface area.

18 . The manufactured part of claim 15 wherein the sub-conductive members are generally evenly spaced apart from each other.

19 . The manufactured part of claim 15 wherein the first portion of the electrically conductive member and each of the sub-conductive members has a longitudinal length and a width in a direction transverse to the length and the width of each of the sub-conductive members is narrower than the width of the first portion of the electrically conductive member.

20 . The manufactured part of claim 15 wherein the first component part is made of wood.

21 . The manufactured part of claim 15 wherein the first component part is made of plastic.
