Abstract

A method for assembling a device on two substantially parallel taut threads. The device includes an electronic chip and two substantially parallel grooves open on opposite sides of the device. The distance separating the grooves corresponds to the distance separating the threads. The device presents a penetrating shape along an axis perpendicular to the plane of the grooves, having a base at the level of the grooves and an apex of smaller size than the distance separating the threads. The method includes the steps consisting in placing the apex of the device between the two threads; in moving the device between the two threads resulting in the threads being separated from one another by the penetrating shape of the device; and in continuing movement of the device until the threads penetrate into the grooves reverting to their initial separation distance.

Claims

1. A method for assembling a device on two threads, comprising the following steps:

providing two substantially parallel taut threads;

providing a device comprising an electronic chip and two substantially parallel grooves open on opposite sides of the device, a distance separating the grooves corresponding to a distance separating the threads, said device presenting a penetrating shape along an axis perpendicular to the plane of the grooves, having;

a base at the level of the grooves, a length of the base being substantially equal to the distance separating the threads, and

an apex having a length that is shorter than the distance separating the threads;

placing said apex of the device between the two threads;

moving the device between the two threads resulting in the threads being separated from one another by the penetrating shape of the device; and

continuing movement of the device until said threads penetrate into the grooves reverting to their initial separation distance.

2. The method according to claim 1, wherein the penetrating shape of the device is conical and comprises a double thread screw with two screw threads each opening out into a respective groove, the method comprising the following steps:

placing the screw threads in contact with the two threads; and

applying a screwing movement to the device.

3. The method according to claim 1, wherein a groove of the device comprises a bump for electric connection, the thread corresponding to the groove provided with the bump being electrically conducting.

4. The method according to claim 1, wherein the device comprises a cover defining the grooves, in conjunction with the electronic chip.

5. The method according to claim 4, wherein the cover has the shape of a pyramid.

6. The method according to claim 4, wherein the cover has the shape of a cone.

7. The method according to claim 1, wherein the threads are consecutive weft threads or consecutive warp threads.

8. A fabric including a device comprising an electronic chip and two substantially parallel grooves open on opposite sides of the device, in which two substantially parallel consecutive threads of the fabric are inserted, wherein the device presents a penetrating shape along an axis perpendicular to the plane of the grooves, having:

a base at the level of the grooves, a length of the base being substantially equal to the distance separating the threads, and an apex having a length that is shorter than the distance separating the threads.

9. The fabric according to claim 8, wherein a groove of the device comprises a bump for electric connection, the thread inserted in the groove provided with the bump being electrically conducting and in electric contact with said bump.

10. The fabric according to claim 8, wherein the device comprises a cover delineating the grooves, in conjunction with the electronic chip.

11. The fabric according to claim 8, wherein in that the cover has the shape of a pyramid.

12. The fabric according to claim 8, wherein in that the cover has the shape of a cone.

13. The fabric according to claim 12, wherein the cone comprises a double thread screw with two screw threads, each screw thread opening out into one of the grooves.

14. The fabric according to claim 9, wherein the electronic chip comprises a light-emitting diode.

15. The fabric according to claim 8, wherein the device comprises four grooves arranged to form a rectangle, in which four threads are inserted forming a stitch of the fabric.

16. The fabric according to claim 8, wherein the threads are consecutive weft threads or consecutive warp threads.
