Description

The invention relates to a trigger device for handguns according to the preamble of claim 1. Such a trigger device is known from DE 3111037 known.

There are already deduction facilities of the type mentioned above, in which the Hammer must first be stretched over the trigger with each shot. By These so-called DAO trigger systems (Double Action Only) is a weapon in a high security guaranteed, since they have a constant trigger resistance and put away after shooting without any additional relaxation can. However, the conventional DAO trigger systems have a fixed Abzugsweg on, so that both the delivery of a first shot as well as for delivery Further shots each equal movement of the trigger is required.

The CH 685 262 A5 is a trigger device of a handgun with a cock, a trigger and cooperating with this trigger bar known. At this known extraction device works the trigger bar together with a cock holder, through the tap in a self-tensioning operation (single action) in a cocked Position and in a double-action operation in a semi-prestressed position (precocked) position is held. When operating the weapon by means of tension trigger of the Tap by moving the trigger bar first over a breaker in the Clamping position moves until the rear end of the tie rod via a stationary bevel is moved down. At the same time the breaker is pivoted upward, causing the contact between the trigger bar and the breaker is interrupted. This allows the tap to advance to firing a shot forward.

The object of the invention is to provide a trigger device for handguns whose Essentially the functionality of a DAO trigger system (Double Action Only) but offers the possibility, starting from the second shot with a substantial Shortened trigger to shoot.

This object is achieved by a trigger device with the features of claim 1 solved. Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

In the trigger device according to the invention is after triggering the first shot the trigger rail already when repeating the shutter by shifting the Spool brought from a lower release position in an upper catch position. As a result, the hammer, which is also taut when repeating, can already be used again be caught and held over the trigger, before leaving his completely relaxed front Starting position reached for the delivery of the next shot. If the trigger is from the shooter After the delivery of the shot is not released, so the next shot with a significantly shortened trigger path are delivered. We the deduction after the Release of the shot released, this moves back to its original position and to deliver the next shot, the complete withdrawal path is required again. This ensures a high level of security, since the gun after shooting without additional relaxation can be put away.

In a particularly advantageous embodiment of the invention, the spool is transverse to Longitudinal axis of the handgun slidably between two spaced apart Side parts of a support element arranged. The spool expediently contains a lower control radius through which the trigger rail in the starting position of the Spool is moved to its release position to release the percussion hammer. Of the Control slide also contains a cutout, in which the trigger rail in the after inside depressed functional position of the spool engages. This gets the Discharge rail in a catch position, in which the also stretched when repeating Hammer can be caught.

To move the spool is in a preferred embodiment of a Spool cross-section side wall of the closure provided a recess, in which engages the spool with closed shutter. If the shutter due the recoil is shifted in the firing, the spool gets out Engages with the recess and is pressed inwards into its functional position. In this Position jumps the trigger rail in the designated cutout of the spool a, whereby again an overlap between a catch catch of the trigger rail and a Feuerrast on the hammer is. At the same time, the spool is replaced by the Retraction rail held in its inwardly depressed functional position. When the through the backward movement of the shutter also cocked percussion hammer then again returns to its original position, he comes even before reaching his Starting position again in engagement with the trigger rail and pushes back, so that the spool moves back to its original position. In this position is a new shot triggering with a significantly reduced trigger path possible.

The spool contains a guide pin and a right-angled control pin, in a corresponding opening of the deduction rail facing side part of the Carrier element is arranged protruding outwards. On the guide pin is a Compression spring arranged through which the control pin of the spool to the adjacent Sidewall of the closure is pressed.
