Abstract

Firearms including a secured firing pin retaining pin, the firearms having a barrel, a sliding block, a bolt head, a firing pin with a flange-like collar, a firing pin retaining pin with a safety device, and a weapon median plane. For facilitating handling, it is provided that the firing pin retaining pin is slidably mounted normally to the weapon median plane in a retaining bore, that it is designed as one piece and to be rotationally symmetrical with a head and a pin end and has two annular grooves. A locking pin mounted in a spring-loaded manner in the sliding block is designed such that, depending on the position of the firing pin retaining pin in the retaining bore, it can optionally engage in one of the annular grooves, which correspond to a holding position and a release position for the firing pin, respectively.

First claim

The invention claimed is:

1. A firearm having a weapon median plane, the firearm comprising:
a barrel;
a sliding block;
a bolt head;
a firing pin, the firing pin being designed as one piece and having a flange-like collar, and
a firing pin retaining pin having a safety device; wherein the firing pin retaining pin is slidably mounted normally to the weapon median plane in a retaining bore; and wherein the firing pin retaining pin is rotationally symmetrical having a head, a pin end, and a first and a second annular grooves; and
a locking pin mounted in a spring-loaded manner in the sliding block; wherein the locking pin is designed to releasably engage with the first or the second annular grooves of the firing pin retaining pin when the firing pin retaining pin is in either a holding position or a release position within the retaining bore.

2. The firearm according to claim 1 , wherein a first annular groove of the firing pin retaining pin is arranged near the head of the firing pin retaining pin and forms a first stop; and a second annular groove of the firing pin retaining pin is arranged near the pin end of the firing pin retaining pin and forms an end stop; and
the first annular groove is arranged on the firing pin retaining pin at a maximum distance of one- third of a length of the firing pin retaining pin from the head of the firing pin retaining pin; and the second annular groove is arranged on the firing pin retaining pin at a maximum distance of one-third of the length of the firing pin retaining pin from the end of the firing pin retaining pin.

3. The firearm according to claim 2 , wherein an engagement of the locking pin with the first annular groove retains the firing pin retaining pin in the holding position, such that the firing pin retaining pin lies in a motion path of the flange-like collar of the firing pin and thereby retains the firing pin within the sliding block.

4. The firearm according to claim 2 , wherein an engagement of the locking pin with the second annular groove retains the firing pin retaining pin in the release position, such that the firing pin retaining pin does not lie in a motion path of the flange-like collar of the firing pin and thereby permits the firing pin to be removed from the sliding block.

5. The firearm according to claim 2 , wherein the second annular groove forming the end stop defines, on a side nearest the pin end, a flank that runs normally to an axis of the firing pin retaining pin and that acts as a locking surface.

6. The firearm according to claim 2 , wherein the first annular groove forming the first stop defines, on both sides of the first annular groove, flanks that run obliquely to an axis of the firing pin retaining pin, each flank forming a run-up slope.

7. The firearm according to claim 1 , wherein an end of the locking pin that faces the firing pin retaining pin corresponds in shape and size to a cross-sectional shape of at least one of the first and second annular grooves.

8. The firearm according to claim 7 , wherein the end of the locking pin that faces the firing pin retaining pin corresponds in shape and size to the cross-sectional shape of the first annular groove.

9. The firearm according to claim 2 , wherein the locking pin is slidably mounted within a locking pin bore defined in the sliding block, and the locking pin bore intersects the retaining bore such that the locking pin can be extracted from the sliding block when the firing pin retaining pin is removed.

10. The firearm according to claim 9 , the sliding block further defining a maintenance opening that leads from a surface of the sliding block to the locking pin bore, wherein the maintenance opening permits the locking pin to be pushed against a force of its spring and away from an area of the end stop of the firing pin retaining pin, enabling the firing pin retaining pin to be removed from the sliding block.

11. The firearm according to claim 1 , wherein the pin end of the firing pin retaining pin has an essentially conical, dome-like, or semispherical shape.

12. The firearm according to claim 1 , wherein the pin end of the firing pin retaining pin defines an indentation in its axial area.

13. The firearm according to claim 12 , wherein the indentation is a blind bore in a form of a conical or a semispherical depression.

14. The firearm according to claim 1 , wherein the head of the firing pin retaining pin is mushroom-shaped.

15. The firearm according to claim 1 , wherein one or both openings of the retaining bore include a conical indentation or depression in a side of the sliding block.

16. The firearm according to claim 15 , wherein the openings of the retaining bore include a conical indentation or depression on both sides of the sliding block.
