Abstract

A fixing tool including a nose for guiding of fixing elements and a striking plate for striking of the fixing elements, wherein the fixing tool is configured to fire a fixing element of a first type and a fixing element of a second type with dimensional and/or geometric characteristics which are different from those of the fixing element of the first type.

First claim

The invention claimed is:

1. A nose for a fixing tool and for guiding of fixing elements provided from a supply store of the fixing tool, the nose comprising:
a stepped wall having a first portion configured to be contacted by a first head of a first fixing element of a first type to position the first head before firing and a second portion configured to be contacted by a second head of a second fixing element of a second type to position the second head before firing, the second fixing element of the second type having one or more dimensional and/or geometric characteristics different from those of the first fixing element of the first type, wherein the first portion is closer to a part of the supply store than the second portion;
a first support area configured to receive the first head of the first fixing element of the first type before firing, the first support area being partially defined by the first portion of the stepped wall; and
a second support area that is spaced from the first support area, the second support area configured to receive the second head of the second fixing element of the second type before firing, the second support area being partially defined by the second portion of the stepped wall.

2. The nose of claim 1 , which partly defines a firing chamber of the fixing tool.

3. The nose of claim 2 , wherein the first support area and the second support area are aligned according to an axis of extension of the stepped wall.

4. The nose of claim 3 , which includes a rim engagable in a groove defined by a striking plate of the fixing tool.

5. A fixing tool comprising:
a supply store configured to hold a plurality of fixing elements to be fired, the plurality of fixing elements including a first fixing element of a first type and a second fixing element of a second type, wherein the second fixing element of the second type has one or more dimensional and/or geometric characteristics different from those of the first fixing element of the first type;
a nose configured to receive the first and the second fixing elements from the supply store, the nose partly defining a firing chamber; and
a striking plate configured to strike each of the first and the second fixing elements after that fixing element is received in the nose;
wherein the nose includes a stepped wall having a first portion configured to be contacted by a first head of the first fixing element of the first type to position the first head before firing and a second portion configured to be contacted by a second head of the second fixing element of the second type to position the second head before firing, wherein the first portion is closer to a part of the supply store than the second portion;
wherein the nose further includes: (i) a first support area configured to receive the first head of the first fixing element of the first type before firing, the first support area being partially defined by the first portion of the stepped wall; (ii) a second support area that is spaced from the first support area and configured to receive the second head of the second fixing element before firing, the second support area being partially defined by the second portion of the stepped wall; and (iii) a rim;
wherein the striking plate defines a groove, the groove being configured to receive the rim of the nose.

6. The fixing tool of claim 5 , which includes a shearing block supported on the nose along a joining plane, wherein the shearing block defines a guide track for the first fixing element and/or the second fixing element, the guide track being opposite the first support area and the second support area.

7. The fixing tool of claim 6 , wherein the shearing block defines a central window extending along a longitudinal axis (X) of the nose.

8. The fixing tool of claim 7 , wherein the shearing block defines two notches that define the guide track, the notches being opposite one another relative to a longitudinal plane of the shearing block and at least partially bordering the window.

9. The fixing tool of claim 6 , wherein the shearing block defines a part of the firing chamber opposite to the part of the firing chamber defined by the nose relative to a plane perpendicular to the longitudinal plane.

10. The fixing tool of claim 6 , which includes a workpiece surface sensor assembly, the sensor assembly being mobile in translation relative to the nose along a longitudinal axis extending from the nose.

11. A fixing tool comprising:
a supply store configured to hold a plurality of fixing elements to be fired, the plurality of fixing elements including a first fixing element of a first type and a second fixing element of a second type, wherein the second fixing element of the second type has one or more dimensional and/or geometric characteristics different from those of the first fixing element of the first type; and
a nose configured to receive the first and the second fixing elements from the supply store, the nose partially defining a firing chamber;
wherein the nose includes a stepped wall having a first portion configured to be contacted by a first head of the first fixing element of the first type to position the first head before firing and a second portion configured to be contacted by a second head of the second fixing element of the second type to position the second head before firing, wherein the first portion is closer to a part of the supply store than the second portion;
wherein the nose further includes a first support area and a second support area, the first support area being configured to receive the first head of the first fixing element of the first type before firing, the second support area being spaced from the first support area and configured to receive the second head of the second fixing element before firing, wherein the first support area is partially defined by the first portion of the stepped wall and the second support area is partially defined by the second portion of the stepped wall.

12. A striking plate for a fixing tool and configured to drive a first fixing element of a first type and a second fixing element of a second type with one or more dimensional and/or geometric characteristics different from those of the first fixing element of the first type, the striking plate comprising:
a striking surface at a first longitudinal end, the striking surface configured to strike a first head of the first fixing element at a first location of a nose of the fixing tool and to strike a second head of the second fixing element at a second location of the nose;
a drive device fixing mechanism at a second longitudinal end opposite the first longitudinal end; and
an elongated body between the first and the second longitudinal ends, the body configured to be slidable in a firing chamber in which the first fixing element or the second fixing element is located, wherein the body defines a longitudinal groove configured to receive a rim of a nose of the fixing tool, the groove being positioned such that it is centered relative to a longitudinal plane on an upper face of the body and extends longitudinally from a position near the second longitudinal end toward and through the striking surface at the first longitudinal end;
wherein the striking plate is symmetrical along the longitudinal plane.

13. The striking plate of claim 12 , which plate defines a first recess and a second recess each disposed on a lower face of the body opposite the upper face in which the groove is disposed, the first recess being disposed on a side of the longitudinal plane and the second recess being disposed on a side of the longitudinal plane opposite the first recess, wherein the first
