Abstract

A device for driving fastening elements into an underlying surface has a mount for a fastening element, having a through-passage for a driving-in element, by which a fastening element in the mount is driven into the underlying surface in a driving-in direction, having a strip lead-through, which defines a strip plane and a transporting direction and is intended for a fastening-element bearing strip core, having a supporting element for supporting the strip and/or a fastening element, and having a supporting spring, wherein the supporting element can be deflected transversely to the driving-in direction, counter to a force of the supporting spring, when a fastening element is moved in the driving-in direction by the driving-in element in order for the fastening element to be separated from the strip.

First claim

The invention claimed is:

1. A device for driving fastening elements into a substrate, the device comprising a holder for a fastening element, a strip comprising a strip core defining a strip plane and a strip longitudinal direction and having fastening elements, which are held on the strip core, a strip transport channel, which defines a transporting direction, for the strip core carrying fastening elements, a passage for a driving-in element, wherein the driving-in element drives the fastening element in the holder in a driving-in direction into the substrate, a supporting element supporting the strip, and a supporting spring, wherein the supporting element is deflected, transverse to the driving-in direction, against a force of the supporting spring, when the fastening element is moved by the driving-in element in the driving-in direction in order to separate the fastening element from the strip, wherein each of the fastening elements has a head, the head loading the strip core against the supporting element when the individual fastening element in the holder is separated from the strip.

2. The device according to claim 1 , wherein the supporting element has a supporting surface, which points in a direction opposite to the driving-in direction or, points at an acute angle to a direction opposite to the driving-in direction, wherein the supporting surface is oriented transverse to the strip plane, in order to support the strip in a direction opposite to the driving-in direction, when a fastening element is moved by the driving-in element in the driving-in direction, so as to separate the fastening element from the strip.

3. The device according to claim 2 , wherein the supporting element is deflected, transverse to the transporting direction, against the force of the supporting spring, when the head of the individual fastening element loads the strip core against the supporting element.

4. The device according to claim 1 , wherein the supporting element is deflected, transverse to the transporting direction, against the force of the supporting spring, when the head of the individual fastening element loads the strip core against the supporting element.

5. The device according to claim 1 , wherein the supporting element comprises the supporting spring.

6. The device according to claim 1 , wherein the strip transport channel has a recess, into which the strip is moved transverse to the transporting direction and transverse to the driving-in direction, when a fastening element in the holder is separated from the strip.

7. The device according to claim 6 , wherein the supporting element is deflected, against the force of the supporting spring, into the recess, when a fastening element is moved by the driving-in element in the driving-in direction, in order to separate the fastening element from the strip.

8. The device according to claim 6 , wherein the head of the fastening element moves the strip core or a supporting foot of the strip core into the recess, when the individual fastening element in the holder is separated from the strip.

9. The device according to claim 1 , further comprising a contact sensor, which feeds a fastening element along the strip transport channel in the transporting direction into the holder, when the device is pressed against a substrate.

10. The device according to claim 1 , wherein the supporting spring is a leaf spring.

11. The device according to claim 1 , wherein the strip core has a counter-supporting surface and wherein the supporting element supports the counter-supporting surface in a direction opposite to the driving-in direction, when a fastening element in the holder is moved in the driving-in direction.

12. The device according to claim 11 , wherein the counter-supporting surface is arranged on a front side of the strip core, which points in the driving-in direction.

13. The device according to claim 11 , wherein the strip core has a transporting recess.

14. The device according to claim 13 , wherein the counter-supporting surface defines the transporting recess.

15. The device according to claim 13 , wherein the fastening elements are held in holders that project, on a side lying opposite the transporting recess, from the strip core transverse to the strip plane.

16. The device according to claim 1 , wherein the holder has a recess, into which the strip is moved transverse to the transporting direction and transverse to the driving-in direction, when a fastening element in the holder is separated from the strip.

17. The device according to claim 1 , wherein the supporting element supports the strip core.

18. The device according to claim 1 , wherein the supporting element supports a fastening element of the strip.

19. The device according to claim 1 , further comprising a contact sensor, which feeds a fastening element along the strip transport channel in the transporting direction into the holder, when the driving-in is ended.

20. The device according to claim 1 , wherein at least one of the fastening elements has a counter-supporting surface and wherein the supporting element supports the counter-supporting surface in a direction opposite to the driving-in direction, when a fastening element in the holder is moved in the driving-in direction.
