Abstract

An automatic combination rifle with a large caliber automatic rifle system and a normal caliber automatic rifle system that include respective triggering arrangements which are connected with a single, movable trigger lever with the use of an activated change-over mechanism. Each triggering arrangement comprises a movable release mechanism to control the respective trigger function. The change-over mechanism establishes a selective connection with one of the release mechanisms for cooperative movement with the trigger lever.

Claims

1. A switch-over mechanism used to selectively couple first actuating means of a first self-loading system with a trigger and second actuating means of a second self-loading system with the trigger in a combination rifle comprising:

an axle coupled with the trigger disposed to provide an axis of rotation for the trigger;

a sleeve mounted on the axle including at least one longitudinally extending gear; and

stop means located at the ends of the axle for defining first and second positions for the switch-over mechanism such that, in the first position the gear engages the first actuating means while being disengaged from the second actuating means, and in the second position the gear engages the second actuating means while being disengaged from the first actuating means.

2. An automatic combination rifle including a first caliber rifle system and a second caliber rifle system, the second caliber rifle system having a smaller caliber than the first rifle system and disposed adjacent to the first caliber rifle system, each of the rifle systems being connected to a movable trigger lever, comprising:

a first triggering mechanism with a first release for actuating the first caliber rifle system;

a second triggering mechanism with a second release for actuating the second caliber rifle system; and

a change-over mechanism for selectively coupling either the first release or the second release with the trigger lever, the change-over mechanism comprises a transverse axle having the trigger lever pivotally mounted thereto and establishes an interconnection between the trigger lever and a selected one of the first or second releases, the transverse axle is movable in the axial direction between first and second end positions and comprises a section with a non-circular cross section which, in each of the end positions, transmits a moment of torsion between the trigger lever and a selected one of the releases.

3. The invention as in claim 2, wherein the transverse axle has two lateral end portions where at least one of the lateral end portions of the transverse axle projects from a handle housing to present a change-over activation button.

4. The invention as in claim 2, wherein the non-circular cross section has a serration profile.
