ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
This invention relates to a hand weapon, such as a pistol, and is particularly concerned with a safety mechanism for locking a disassembly lever to thus prevent an accidental firing of the weapon in the course of a disassembling operation.
European Patent No. 77,790 describes a pistol having a frame and a slide which is displaceable thereon and in which a breechblock (also referred to as “bolt”) is disposed. A spring-loaded firing pin, having a firing pin catch, is slidably received in the bolt. To a pivotal trigger a trigger rail is articulated which, at its rear, is jointed to a sear lever which arrests and holds the firing pin catch during the forward motion of the slide/bolt assembly, whereby the firing pin spring is armed. Upon pulling the trigger, the rearward end of the trigger rail runs up on a control cam of a leaf spring and, as a result, the trigger rail is lowered. This occurrence also causes a lowering of the sear lever and thus the firing pin is released and urged forwardly by the firing pin spring. After a shot is fired, the slide recoils on the frame. At the same time, a cam track provided on the bolt laterally displaces the leaf spring so that its control cam is out of engagement with the trigger rail and thus the latter, together with the sear lever, is pivoted upwardly. Thereafter, during the successive forward motion (recuperating motion) of the slide, the firing pin catch is again caught by the sear lever.
The above-described trigger mechanism is relatively complicated and requires a great number of individual components. Since the sear lever, during arming of the firing pin spring, executes a pivotal motion, it may only provide a linear contact with the firing pin catch which results in a relatively substantial wear and requires significant main tenance. The bolt is separately installed in the slide which increases manufacturing costs.
In case the above-described prior art pistol is to be disassembled, first the magazine is removed from the grip well and by performing a charging operation (that is, by pulling back and releasing the slide), a cartridge which may have remained in the pistol chamber is ejected. A transverse pin which secures the slide on the frame is depressed. Since the firing pin catch is still held back by the sear lever, in this position the slide may not yet be pulled off in a forward direction from the frame. To allow such a removal, first the trigger has to be pulled. In case an earlier loading motion has not been fully performed or in case the unloading operation has been performed in a reverse sequence, risks are considerable that an unintentional and thus uncontrolled shot is fired.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved pistol of the above-outlined type from which at least one of the above-discussed disadvantages is eliminated.
This object and others to become apparent as the specification progresses, are accomplished by the invention according to which, briefly stated, the pistol includes a frame; a slide reciprocating on the frame between a forward position and a pulled-back position; a firing pin mounted in the slide for motions relative to the slide; a firing pin catch affixed to the firing pin; a firing pin spring mounted in the slide and urging the firing pin forwardly; a trigger supported in the frame; a trigger rail coupled to the trigger for executing a triggering motion when the trigger is pulled; and a sear for connecting the trigger rail with the firing pin catch such that during forward motion of the slide the sear arrests and holds the firing pin catch thus arming the firing pin spring and that upon pulling the trigger, the sear is moved away from the firing pin catch by the trigger rail for allowing the firing pin to accelerate forwardly. A manually operable disassembly member which has an open and a closed position, is movable into a pulled-out state for allowing the slide to be taken off the frame. A first cooperating locking arrangement is provided on the frame and the disassembly member for allowing the disassembly member to be moved into the pulled-out state solely in the open position of the disassembly member. A second cooperating locking arrangement is provided on the slide and the disassembly member for allowing the disassembly member to be moved from the closed position into the open position solely in the pulled-back position of the slide.
