The invention concerns a pistol with a frame and slide and in particular the detachable combination of the frame and slide corresponding to the generic concept of claim 1.
U.S. Pat. No. 5,024,139 (Knight) discloses a semi-automatic, double action only pistol with a rotating barrel that is disassembled upon the removal of the magazine and the manipulation of a lever located on the frame by turning the lever 90°. This rotation brings a notch out of the way of a barrel lug thus allowing the slide to move forward until it disengages from its guides on the frame. The pistol according to U.S. Pat. No. 4,984,504 (Beretta) also uses a lever located on the frame for disassembly.
U.S. Pat. No. 1,427,966 (Nickl) discloses a similar rotating barrel pistol that is designed with a disassembly mechanism located in the frame. One of the main differences between Nickl and Knight/Beretta is that the disassembly mechanism in Nickl is a pin that must be pushed against a spring perpendicular to the symmetry plane of the pistol in order to allow the displacement of certain parts in the slide.
The content of the three mentioned documents is hereby incorporated by reference in their entireties for all purposes, and shall therefore become an integral part of this description for all jurisdictions in which this is possible.
Disassembly of a pistol requires separating the slide from the frame of the pistol. While there are various approaches to disassembling pistols, the present invention's purpose is to provide an alternative takedown system based on a slide mount mechanism.
This object is accomplished according to the present invention by the characterizing part of claim 1, in other words, the slide mount is fitted on a component connected to the firing pin guide (spacer sleeve), so that the slide can be moved forward when the mount is released, while the firing pin and its carrier remain behind the trigger edge of the trigger bar in the frame. The mounting component together with the firing pin can either be removed from the slide or it can only be pushed back far enough in the slide, while being captive, if the slide is moved forward and is then removed from the frame together with the slide once the guides between the slide and the frame are no longer engaged.
With other words, all parts necessary for dismantling are concentrated on the slide and its parts. To say so, the invention relates to a pistol with a frame, in which there is a trigger mechanism and with a slide movable along guides in the frame which are preferably parallel to the axis of the barrel, in the slide a barrel, a recoil spring and a firing and holding mechanism are located, the latter comprises a firing pin, which is movably mounted in a firing pin guide (spacer sleeve), the pistol is characterized by the fact that, the mechanism for disassembling the slide from the frame is situated in the slide only.
Features, functions, and advantages may be achieved independently in various embodiments of the present disclosure, or may be combined in yet other embodiments, further details of which can be seen with reference to the following description and drawings.
In the description and the claims the terms “front”, “back”, “top”, “bottom” etc. are used in the generally accepted form and with reference to a pistol, in the usual manner. This means that the muzzle of the barrel is at the “front”, that the slide is displaced backwards by the explosive gases, etc. The description is based on a pistol with a rotating barrel; however the invention is not limited to the described and shown embodiments.
As can be seen in
The firing and holding mechanism 6 has a firing pin guide (spacer sleeve) 11, around which there is a pivoting holding plate 12, which is primarily normal to the axis of the firing pin 7 which protrudes to the outside. This holding plate 12 is, when mounted, retained in a holding notch 13 in the slide 3. At the bottom end, facing the frame 2, the holding plate 12 has a stop retainer 14, which in mounted condition, is held by the force of the recoil spring 5 on a surface, the stop level 15, of the frame 2 and prevents the slide 3 from being able to move any further forward than that.
As shown in
When dismantling the pistol, it is then necessary to release the firing and holding mechanism 6, as shown in
This is shown in
It can also be seen in
A plunger lock 24 (
Further dismantling is then possible by pushing the plunger lock 24 from the underside of the slide 3 against the spring force, if necessary by way of the interaction of the plunger lock 24 with the depressure plunger bearing 22, so far that the firing and holding mechanism 6, in accordance with the bulge in the plunger lock 24, to move out of that area so that it can be removed from the slide 3. In the same way, the extractor group 27 and the safety mechanism 10 can also be dismantled or removed from the slide 3.
As is immediately evident, the three functional assemblies:
Due to the invention's combination of features it is also possible to, irrespective of the movement of the slide 3, to separate the firing and holding mechanism 6 on the one hand and the trigger mechanism 9 on the other hand, which has not been possible until now.
Although the present invention has been shown and described with reference to the foregoing operational principles and preferred embodiments, it will be apparent to those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention. The present invention is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
