DESCRIPTION:
BRIEF SUMMARY
The invention concerns a safety device for firearms, especially for rifles, to prevent the accidental discharge of a round.
Safety devices are known in which a press button is acting directly on a trigger element actuating the firing pin, for example a safety catch. These devices have the disadvantage that if the firearm drops to the ground or when the safety catch is broken, a shot may be discharged even though the weapon is secured. Safety devices are further known, in which the firing pin is arrested by means of a press button through a comparatively complex lever gear mechanism. These devices are again unable to provide complete safety.
A further disadvantage of the known safety devices consists of the fact that for safety reasons the safety press button must be located as far as possible from the trigger, with the consequence that to release the weapon, the finger must be taken from the trigger and the release of the safety immediately prior to firing is not possible.
It is the object of the present invention to provide a safety device which offers the highest possible degree of safety by the fact that in the safety position both the trigger and the bolt and the firing pin are locked. Furthermore, the release of the safety device should be possible from the trigger guard. Finally, the device should be capable of preventing the accidental dropping of the bolt from the weapon in the unsecured state, but should not interfere with the intentional removal of the bolt.
The attainment of this object is characterized in the principal claim. The device according to the invention provides a triple safety effect, by that the trigger, the bolt and the firing pin are immobilized. Furthermore, the rifleman will note immediately upon the insertion of his finger into the trigger guard whether the weapon is secured. He is then able to effect its release during the aiming process. Finally, there is no danger in the case of the device according to the invention that the bolt will be pulled out unintentionally in the unsecured state, for example during the repeating of the weapon.
An example of the embodiment of the weapon is shown in the drawing as an example. In the drawing:
FIGS. 1 and 2 show the safety device in the safety and the release state, and
FIGS. 3 and 4 show the safety in the safety and the release state relative to removal of the bolt.
FIG. 5 is an enlarged view of a spring and lever assembly which acts upon two slides when the latter are in their release state corresponding to FIG. 2.
The drawing shows a trigger block 1 in combination with a conventional rifle, of which only part of the bolt 15 and of the firing pin 16 are indicated. Under the trigger block 1 a trigger guard 2 is located; it defines the path of the movement of the trigger 4.
The unit consisting of the trigger 4 and the trigger body 6 is articulated to the trigger block 1 at 5. The trigger 4 may be pivoted within the guard 3, while the trigger body 6 is actively connected with a conventional trigger element of the lock, not shown.
Two slides 7 and 8 are associated with the trigger block; they are arranged adjacently to each other and may be displaced perpendicularly to the longitudinal axis of the bolt 15, while guided in grooves located in the block 1. The two slides 7, 8 are connected with each other by means of a double arm lever 9, so that the lower end at least of the slide 8 extends into the space 3 defined by the guard 2.
The lever 9 has to lever arms 9a and 9b, the free ends of which are engaging articulation sockets of the slides 7 and 8, and a center piece 9c connecting the two lever arms with each other. The center piece 9c is cylindrical in configuration, with the longitudinal axis of the cylinder extending perpendicularly to the plane of the drawing, and is bearingly supported in a small bearing block 10 with a cylindrical supporting surface and fastened to the trigger block 1.
The end of a spring 13 is fastened to the center piece 9c of the lever 9 and eccentrically to said lever, with the other end of the spring being connec
