Abstract

A firing device for firing cartridge ammunition comprising a case head, which has on its outer circumference at least one peripheral, groove-shaped depression. In order to achieve secure arrestment of the ammunition in the firing device when the firing device is loaded from the muzzle end, a head piece and a tubular ammunition receiving-device is provided, wherein the ammunition receiving-device is arranged such that it can be moved axially in the direction of the head piece against the pressure of a restoring element. In this case, the head piece includes an annular guiding element, which extends axially into the ammunition receiving-device and has multiple guiding openings, which extend through the wall of the guiding element and are in each case of a form that is angled from the outer side of the guiding element in the direction of the opening of the ammunition receiving-device.

First claim

The invention claimed is:

1. A firing device for firing cartridge ammunition with a case head, having on its outer circumference at least one circumferential, groove-shaped depression, the firing device comprising:
a head piece; and
a tubular ammunition receiving-device fixed to a front-side of the head piece;
wherein the ammunition receiving-device is slidably mounted against the pressure of a restoring element, axially in the direction of the head piece; and
wherein the head piece has an annular guiding element, which axially extends inside of the ammunition receiving-device, such that when the firing device is loaded with the ammunition, the groove-shaped depression of the ammunition is at least partially enclosed by the annular guiding element.

2. The firing device according to claim 1 , wherein the annular guiding element includes multiple guiding openings, in each of which a locking element is slidably disposed, and which are arranged distributed over the periphery and which extend through a wall of the guiding element.

3. The firing device according to claim 2 , wherein the guiding openings are each obliquely directed from the outside of the guiding element to a muzzle of the ammunition receiving-device.

4. The firing device according to claim 2 , wherein the locking elements are acted upon by spring elements, on the side facing away from the ammunition receiving-device, such that when the firing device is loaded with the ammunition, the locking elements of the spring elements are pressed into the groove-shaped depression of the ammunition to lock the ammunition.

5. The firing device according to claim 4 , wherein the locking elements are displaceably arranged by the ammunition receiving-device in such a way that upon an axial displacement of the ammunition receiving-device in the direction of the head piece, the locking elements are slidable against the pressure of the spring elements from the groove-shaped depression of the ammunition into the guiding openings of the guiding element, so that the locking of the ammunition is lifted by the locking elements.

6. The firing device according to claim 4 , wherein the spring elements acting on the locking elements are wave springs.

7. The firing device according to claim 6 , wherein the wave springs circumferentially surround the annular guiding element and abut against a first side of a movable ring that is slidably mounted on the annular guiding element, wherein a second side of the movable ring, that opposes the first side, abuts the locking elements, such that the wave springs act on the locking elements via the movable ring.

8. The firing device according to claim 4 , wherein the locking elements are cylindrical pins, wherein the cylindrical pins each have a cylindrical body portion and two end faces, and wherein the cylindrical body portion contacts the groove-shaped depression when the ammunition is locked.

9. The firing device according to claim 2 , wherein the locking elements are pin-shaped.

10. The firing device according to claim 2 , wherein the locking elements are cylindrical pins.

11. The firing device according to claim 10 , wherein the cylindrical pins are each slidable in a direction that is transverse to the longitudinal axis of the cylindrical pins.

12. The firing device according to claim 1 , wherein the head piece and the ammunition receiving-device are detachably interconnected.

13. The firing device according to claim 12 , wherein the head piece and the ammunition receiving-device are interconnected via a bayonet connection.

14. The firing device according to claim 1 , wherein the restoring element is a spring.
