Safety device for firearms with a firing pin lock

Abstract

The present invention provides a device wherein the safety is arrested in a position in that secures the weapon. The safety shaft, while securing the weapon, is fixed in such a way that any force applied to the safety wing cannot result in a movement of either the safety wing or the safety shaft.

Description

[0001] This invention relates to a safety device for firearms with a firing pin lock to prevent the unintended unlocking of the firearm wherein the safety device comprises a rotatable safety shaft connected to the firing pin lock with locking surfaces. The safety shaft is adjustable in at least two positions for locking of at least the firing pin.BACKGROUND OF INVENTION[0002] Hunting rifles and other firearms are commonly equipped with safety devices, which prevent unintended unlocking of the firearm. These safety devices secure the trigger so that it cannot be actuated. A safety device where the trigger is secured, is described in DE 78 449. Other safety devices function by securing the firing pins.[0003] Safety devices where both the trigger as well as the firing pin or bolt are secured are also known--the art. An example of such a safety device is described in EP 0 143 625 B1. A safety shaft, which is affixed at the firing pin lock, can be set to three positions. The adjustment i...

Benefits of technology

[0006] The present invention provides a device wherein the safety shaft is arrested in a position in that secures the weapon. The safety shaft, while securing the weapon, is fixed in such a way that any force applied to the safety wing cannot result in a movement of either the safety wing or the safety shaft.

[0010] A completely immobile alignment of the lock bar in its longitudinal direction is accomplished by inserting the lock bar into a slot--shaped like the lock bar--wherein the slot is located alongside the firing pin lock. This slot confines the lock bar so that even shearing the hinge pin on the wing will not bring the wing out of the secure or securing-position. The slot is mounted from an axial view of the weapon in front of the safety shaft and partly uncovers the bore for the safety shaft. Therefore, the safety shaft, and especially the herein existing flattening for the lock bar, is accessible. The mounting of the lock bar in this configuration is very advantageous, if the lock bar is affixed perpendicular to or at the firing pin lock. In this configuration, the safety wing and lock bar are then ergonomically situated towards each other. The lock bar is swiveled out with pressure of the index finger or the middle finger while at the same time the safety wing is pushed forward with the thumb. To release the weapon it is necessary to unlock the firing pin lock by pressure from the side and then by pressure from behind in the direction of firing. The simultaneous application of pressure in two different directions greatly reduces or eliminates the possibility of an unintentional discharge of the weapon. Finally, the matching fitting of the lock bar prevents a shearing of the retaining pin--even under extreme forces--at the safety wing.

Problems solved by technology

A shot however cannot be fired, since the lower part of the safety shaft has not unlocked the trigger.

These safety devices, however, suffer from the disadvantage that the safety wing can be unintentionally pushed forward from the secure position, especially while climbing an elevated blind, and when the weapon is jarred or bumped during normal use when hunting.

Since for the release of the safety using such a safety device requires only that the safety wing pass an angle of rotation less than 180.degree., the inadvertent release of the safety during normal use of the weapon cannot be excluded.
