Abstract

Disclosed is a magazine attachment for a device for driving fastening elements into a support, comprising an attachment part which has a connecting region for connecting the magazine attachment to the device, and a pressing part which has a contact region for placing the magazine attachment against the support. The attachment part and the pressing part are held together in such a way as to be movable along a movement path which is delimited by a normal position and a pressing position. An outer contour of the pressing part has three contact points which define two half-lines forming a right angle. In the normal position and in the pressing position, the attachment part and the pressing part are entirely located within a volume formed by the right angle and a straight line that intersects the two half-lines at the vertex of the right angle.

First claim

The invention claimed is:

1. A magazine attachment for a device to drive fastening elements into a first wall, the magazine attachment comprising an attachment part having a connecting area to connect the magazine attachment with the device, and a pressing part having a support region to place the magazine attachment in contact with the first wall and a second wall, wherein the first wall and the second wall are perpendicular to each other, defining a right-angle angular field between them, the first wall providing a first half-line and the second wall providing a second half-line, the first and the second half-lines contacting each other at a vertex and spanning the right-angle angular field,
the support region having an outer contact region for contacting the first wall and the second wall; wherein the attachment part and the pressing part are held next to one another so they can move along a movement path, wherein the movement path is delimited by a normal position and a pressing position,
wherein the outer contact region of the support part has three support points, each of the three support points for contacting the first wall or the second wall, and
wherein the attachment part and the pressing part, when in the normal position and in the pressing position, are situated completely within the right-angle angular field.

2. The magazine attachment of claim 1 , wherein the attachment part and the pressing part, when in the normal position and in the pressing position, are situated completely within the right-angle angular field and a line vertically intersecting the first and second half-lines at the vertex.

3. The magazine attachment of claim 2 , wherein the movement path is linear and defines a driving direction that is oriented within the right-angle angular field and is inclined relative to the first and second half-lines spanning the right-angle angular field.

4. The magazine attachment of claim 1 , wherein the movement path is linear and defines a driving direction that is oriented within the right-angle angular field and is inclined relative to the first and second half-lines.

5. The magazine attachment of claim 4 , wherein the driving direction is inclined relative to a first of the first and second half-lines by an angle between 5° and 30°, and relative to a second of the first and second half-lines by an angle between 60° and 85°.

6. The magazine attachment of claim 1 , wherein two of the three contact points are situated at a distance between them of at least 8 mm on one of the first and second half-lines.

7. The magazine attachment of claim 6 , wherein two of the three contact points are situated at a distance between them of at least 40 mm, on one of the two half-lines.

8. The magazine attachment of claim 1 , wherein the third contact point is situated at a distance of at least 5 mm from the vertex.

9. The magazine attachment of claim 8 , wherein the third contact point is situated at a distance of at least 10 mm from the vertex.

10. The magazine attachment of claim 1 , wherein at least one of the three contact points is situated at a distance of at least 30 mm from the vertex.

11. The magazine attachment of claim 10 , wherein at least one of the three contact points is situated at a distance of at least 60 mm from the vertex.

12. The magazine attachment of claim 1 , wherein the outer contour of the pressing part has three additional contact points, which define additional first and second half-lines spanning an additional right-angle angular field having a vertex, and wherein the attachment part and the pressing part, when in the normal position and in the pressing position, are situated completely within the additional right-angle angular field and a line intersecting the additional first and second half-lines at the vertex of the additional right-angle angular field, and wherein the right-angle angular field and the additional right-angle angular field define planes that are inclined toward one another.

13. The magazine attachment of claim 12 , wherein the right-angle angular field and the additional right-angle angular field define planes that have right angles relative to one another.

14. The magazine attachment of claim 1 , wherein the pressing part has a feedthrough for a fastening element and a transport mechanism, with the aid of which a fastening element can be transported along the feedthrough into a holder if the pressing part is pushed relative to the attachment part from the normal position into the pressing position and/or vice versa.

15. A fastening system comprising a device to drive fastening elements into a support and the magazine attachment according to claim 1 , wherein the connecting area can be connected with the device.

16. The fastening system of claim 15 , wherein when the device is in the normal position and in the pressing position, the magazine attachment is situated completely within the right-angle angular field.
