Abstract

A method of anchoring a connector element (10) in a receiving object (66) comprises inserting a distal end of the connector element (10) into a mounting hole in an insertion direction along an insertion axis; inserting a sleeve (36) comprising a thermoplastic material into the mounting hole, the sleeve (36) enclosing the connector element (10); and transferring energy to liquefy at least a portion of the thermoplastic material of the sleeve (36). A machine (500) configured for carrying out the method and a connector element anchoring kit comprising a connector element (10) and a sleeve (36) comprising thermoplastic material.

First claim

The invention claimed is:

1. A method of anchoring a connector element in a receiving object, the receiving object having an anchoring region provided with a mounting hole for receiving the connector element made of a relatively non-thermoplastic material, and the connector element having a distal end and a proximal end, the proximal end being provided with a first connector interface for engaging with a mating second connector interface, the method comprising:
inserting the distal end of the connector element into the mounting hole in an insertion direction along an insertion axis (A);
inserting a sleeve comprising a thermoplastic material into the mounting hole, the sleeve enclosing and being unbonded to the connector element; and
transferring energy to liquefy at least a portion of the thermoplastic material of the sleeve.

2. The method according to claim 1 , wherein the sleeve and the connector element are pre-assembled and inserted into said mounting hole simultaneously.

3. The method according to claim 1 , wherein the energy is transferred by means of mechanical energy transfer.

4. The method according to claim 1 , wherein the liquefaction of the thermoplastic material is initiated at a liquefaction initiation interface between the sleeve and the connector element.

5. The method according to claim 4 , wherein said liquefaction initiation interface is located at a distal end of the sleeve.

6. The method according to claim 1 , wherein the energy is transferred to sequentially liquefy a plurality of axially separate portions of the thermoplastic material of the sleeve.

7. The method according to claim 1 , wherein the distal end of the connector element is moved into an axial end position, in which it abuts an axial support face of the mounting hole, prior to liquefying said at least a portion of the thermoplastic material.

8. The method according to claim 1 , wherein the anchoring region comprises a solid material which is penetrable by the thermoplastic material of the sleeve when liquefied, the method further comprising
allowing at least a portion of the liquefied thermoplastic material to penetrate into the penetrable material.

9. The method according to claim 1 , further comprising
allowing at least a portion of the liquefied thermoplastic material to axially enclose a structure extending radially from a body of the connector element, and thereafter allowing the liquefied thermoplastic material to solidify to provide axial support between the connector element and the anchoring region.

10. The method according to claim 1 , further comprising allowing at least a portion of the liquefied thermoplastic material to enclose a tangentially varying surface structure of the connector element, and thereafter allowing the liquefied thermoplastic material to solidify to provide rotation resistance to the engagement between the connector element and the anchoring region.

11. The method according to claim 1 , wherein the receiving object is a furniture part, or a blank for forming a furniture part.

12. The method according to claim 1 , wherein the first connector interface is a female connector interface for engaging with a male connector interface.

13. The method according to claim 1 , further comprising moving a proximal end of the sleeve in the insertion direction while said at least a portion of the sleeve is liquefied.

14. The method according to claim 1 , wherein the connector element is inserted into the mounting hole to a position in which it is flush with, or countersunk into, an outer surface of the receiving object, and/or the sleeve is moved to a position in which a proximal end of the sleeve is flush with, or countersunk into, said outer surface of the receiving object.

15. A machine configured for carrying out the process according to claim 1 .

16. The method according to claim 3 , wherein the means of mechanical energy transfer comprises mechanical vibration.
