PISTOL

Abstract

A pistol having a handle piece, a slide that is movable on the handle piece along guides, and a barrel. Provided in the handle piece is a blocking device for the forward movement of the barrel, where the blocking device has a retaining platelet that is movable in a slot and is under the action of a spring, for a barrel projection. A spring platelet is provided in the slot between the spring and the retaining platelet, where the spring platelet is designed such that it can be partially extracted from the slot transversely with respect to the center plane of the pistol. In this extracted position, the spring platelet is pivotable, together with the retaining platelet, against the force of the spring, with the result that the retaining platelet passes out of the movement path of the barrel projection and the slide can be withdrawn forward.

Claims

6. A pistol, comprising: a handle piece having guides thereon; a slide that is movable on the handle piece along the guides; a barrel having a barrel projection; and a blocking device provided in the handle piece that is configured so that when the blocking device is in a retaining position, the blocking device blocks the forward movement of the barrel, wherein the blocking device includes: a retaining platelet that is movably disposed in a slot in the handle piece; a spring configured to apply a force to the retaining platelet so that the retaining platelet is disposed in a movement path of the barrel projection; and a spring platelet that is disposed in the slot between the spring and the retaining platelet and configured so that the spring platelet can be partially extracted from the slot transversely with respect to a center plane of the pistol, and when the spring platelet is partially extracted it can be pivoted with the retaining platelet against the force of the spring, so that the retaining platelet is removed from the movement path of the barrel projection.

7. The pistol of claim 6, wherein the retaining platelet is substantially “A”-shaped and the spring platelet is substantially “U”-shaped, so that when the blocking device is disposed in the retaining position, the legs of the retaining platelet and the legs of the spring platelet are opposed to one another, and contact one another at latching surfaces disposed at the ends of their respective legs.

8. The pistol of claim 7, wherein when the blocking device is disposed in a release position, a leg of the “U”-shape of the spring platelet nests in a concavity defined by the “A”-shape of the retaining platelet, and a leg of the “A”-shape of the retaining platelet nests in a concavity defined by the “U”-shape of the spring platelet.

9. The pistol of claim 7, wherein when disposed in the retaining position, an overall height of the retaining platelet and the spring platelet in combination is greater than a depth of the slot.

10. The pistol of claim 1, wherein the spring platelet defines an undercut or hook shape, and the retaining platelet defines a complementary undercut or hook shape, such that an interaction between the two undercut or hook shapes limits an extent to which the spring platelet can be extracted.

Description

[0011] The invention is explained in more detail hereinbelow with reference to the drawing, in which

[0012] FIG. 1 shows a perspective view of a blocking slider according to the invention in its application on a pistol with a rotating barrel,

[0013] FIGS. 2a to 2d show the barrel and the retaining platelet in the blocking position in four different views in a pistol corresponding to FIG. 1,

[0014] FIGS. 3a to 3c show a pistol formed according to the invention in a side view and rear view and along the section C-C of FIG. 3a,

[0015] FIGS. 4a to 4c show corresponding views of the various positions of the individual parts during disassembly or assembly, and

[0016] FIG. 5 shows the removal of the slide from the handle piece.

[0017] In the description and the claims, the terms “front”, “forward”, “rear”, “rearward”, “top”, “upward”, “bottom”, “downward” and so on are used in the common form and with reference to a pistol which is held in the customary manner. This means that the mouth of the barrel is at the “front”, that the breech or slide is moved “rearward” by the explosion gases, etc.

[0018] FIG. 1 shows a perspective view of a blocking slider according to the invention in a purely schematic manner and limited exclusively to the region of the blocking slider with a schematically indicated barrel, without going into the details of the pistol itself. Provided in a handle piece 1 is a slot 2 which extends obliquely to the barrel axis 3 and transversely through the weapon. In the case of pistols with a drop barrel, the barrel axis 3 represented as reference is the axis which the barrel has with respect to the handle piece if it is in its rest position before the firing of a shot. A blocking slider consisting of two platelets is accommodated in the slot 2 which, with respect to the plane normal to the barrel axis 3, is slightly inclined from top front to bottom rear (in FIG. 1, the mouth of the barrel is on the left-hand side, with the breech, the firing mechanism and the handle being considered to be on the right-hand side). Said blocking slider has an upper retaining platelet 4, which, depending on its position along the axis of a helical spring 7, interacts with a projection 5 of the barrel or not, and a lower platelet, a spring platelet 6, onto which the helical spring 7 presses obliquely from the bottom in the direction of the slot 2 so as to press said spring platelet upward in the direction of the barrel 8.

[0019] In the mounted state, and when viewed for instance in the direction of the barrel axis 3, the retaining platelet 4 has the shape of an “A” in rough outline. Its central part is designed here such that it is guided with slight play in the direction transverse to the weapon by the flanks of the handle piece 1 or strip-like projections provided specially therefor or a plurality of punctiform projections provided specially therefor. The spring platelet 6 substantially has the shape of a “U”.

[0020] FIG. 1 shows the situation in which the spring platelet 6 has been partially extracted from the slot 2 into the release position from its customary locking position with the aid of a projection 10, which serves as a grip, transversely to the center plane of the pistol. For this purpose, the spring platelet 6 is dimensioned such that, even in the blocking position, the projection 10 has a small spacing from the outer wall of the handle piece 1 at this point in order that it can be rearwardly engaged by means of a finger or fingernail and extracted.

[0021] It should be noted that, owing to the U shape of the spring platelet 6 with an oblique groove wall 11 on its extraction side, an upward movement within the groove in the direction of the axis of the spring 7 toward the barrel occurs during the extraction, wherein at the same time the extraction-remote end of the spring platelet 6 on an oblique groove surface 11′ on the underside of the retaining platelet 4, and, during this extraction, the spring platelet 6 carries out no, or at least no noticeable, rotary movement, but is displaced then only at first transversely to the axis of the spring 7. This is achieved by the parallel formation of the groove wall 11 with the groove surface 11′. Furthermore, the hook-shaped formation of the mutually facing surfaces of the two platelets causes a limitation of the extraction movement of the spring platelet 6, and the retaining platelet 4 is guided and secured by a narrowing above the slot and an analogous narrowing of the retaining platelet 4.

[0022] Furthermore, it is of importance that the extraction-remote part of the spring platelet 6 is of undercut design and comes into flat contact with an oppositely undercut groove surface of the retaining platelet 4, with the result that, in the position shown in FIG. 1, the two platelets are positively connected to one another, and a separation is possible only in the direction of the two oblique groove surfaces 11. If the position represented has been reached, it is easily possible for the user to press the remote end 12 of the retaining platelet downwardly against the force of the spring 7 and, owing to the geometric conditions (the narrowing of the slot is tailored thereto), it occurs that the retaining platelet 4 is rotated with the spring platelet 6 like a single platelet in the clockwise direction about the support of the retaining platelet 4 on the upper surface of the slot 2, which is possible as a result of the design of the outer flanks of the retaining platelet 4 and the corresponding mating surfaces in the interior of the handle piece 1. This rotation causes the uppermost region, the retaining region 14, of the retaining platelet to pass out of the movement path of the barrel projection 5 and the barrel, together with the slide, can be withdrawn forward.

[0023] As known from the prior art, it is possible through the corresponding formation of bevels on the front side of the retaining platelet 4 and the rear side of the barrel projection 5 (mouth at the front) to dispense with a corresponding manual release during assembly as long as only the spring platelet 6 is in the release position represented.

[0024] FIGS. 2a to 2d show the situation only with the barrel 8 and the two platelets 4 and 6 in the retaining position: the two platelets rest on one another by way of their mutually facing latching surfaces (designated equally by 9) each provided at the end of the legs of the “A” and of the “U”. The “U” shape and the “A” shape give rise to an opening in the central region and the retaining region 14 assumes the uppermost position which is closest to (or contacts) the barrel 8. A comparison with the release position of FIG. 1 shows the considerably greater height of the two plates as a whole in this retaining position. Here, the barrel projection 5 bears on the retaining region 14 such that it cannot move forward past it in the direction of the axis 3 in the direction of the arrow V; the barrel 8, and thus the slide 16, is fixed (movably) on the handle piece.

[0025] FIG. 3a shows a side view of a pistol 15 with a handle piece 1 and a slide 16 and also the retaining device 17 explained with reference to FIGS. 1 and 2. The barrel mouth (at the front) is on the left in the illustration, with the carriage 16 above the handle piece 1.

[0026] FIG. 3b shows the view in the direction of the arrow B; the spring platelet 6 is extracted laterally from the handle piece out of its rest position—operating position —; its projection 10, which facilitates this extraction, can be seen clearly, as can the extraction-side shoulder of the oblique groove wall 11.

[0027] FIG. 3c shows the section C-C of FIG. 3a, likewise with extracted spring platelet 6. The spring 7, by which it is urged toward the barrel 8, can be seen clearly, as can the retaining platelet 4. The slot 2, which contains the platelets and partially also the spring, has a dimension away from the barrel 8 that allows the removal of the slide 16 explained hereinbelow.

[0028] If, in the position between slide and handle piece illustrated in FIG. 3, the spring platelet is, as illustrated in FIG. 4, pivoted in the clockwise direction by a force being exerted, for unlocking, in the direction of the arrow E on the part of the spring platelet 6 projecting from the handle piece, the spring platelet 6 and retaining platelet 4 are rotated together against the force of the spring 7 about the outer edge of the handle piece in the region of the support 13 (FIG. 1), with the result that the retaining region 14 passes out of the movement path, which extends parallel to the axis 3, of the barrel projection 5; the barrel and slide can be moved forward along the guides 18 between them and the handle piece until the position in FIG. 4 has been reached.

[0029] FIG. 4 shows, in the same illustrations as FIG. 3, the situation directly before lifting off the slide in the upward direction. Only the most important reference signs have been entered; what should be noted is the rotation of the spring platelet 6 together with the retaining platelet 4 as a result of the engagement of the undercuts or hooks of the two platelets. Consequently, the overall height thereof is also reduced and allows pivoting about the outer edge of the retaining region 14. In the position of the slide with respect to the handle piece that is shown in FIG. 4, the guides 18 between these two parts have come out of engagement, and, as shown in FIG. 5, the slide 16 can be lifted off from the handle piece 1.

[0030] The invention is not restricted to the example which has been represented and described, but can be modified in a variety of ways. Thus, particularly an adaptation to the drop barrels mentioned at the outset is no problem for a person skilled in the art with knowledge of the invention; the axis 3 then corresponds to the position of the barrel axis in the ready-for-firing state. The reasons for the oblique position of the slot 2 have been dealt with at the outset, it of course being possible to choose another orientation or to provide the slot in a plane normal to the axis 3.

[0031] The shape of the platelets can vary, it only being essential that pivoting of the two platelets is ensured in the extracted position of the spring platelet. The fact that, as in the example illustrated, positive securement is achieved in addition to the spring 7 in the use mode, because the overall constructional height of the two platelets in the direction of action of the spring 7 is large enough for the barrel projection 5 to be securely held, is a bonus but not a necessity.

[0032] The material employed can be all the materials also used hitherto in the prior art, with the production and processing also presenting no problem with knowledge of the invention.
