Abstract

The invention relates to a pistol (1) with a frame (2), a closure (3) movable thereon and a rotary run (4) located in the closure. The rotation is rotated by cams and grooves with respect to the closure between a locked position and an open position and moved axially. In order to avoid the usual wear in such weapons wear is provided that the closure (3) has an obliquely to the axis of the soul extending abutment surface (11), and the barrel a corresponding contact surface (18). Thus, when locking by the surface contact between these surfaces (11, 18), the beginning of the relative rotational movement is initiated. Thus, it is possible to reduce the wear by orders of magnitude by precisely guided and directed interaction.

Description

  • The invention relating to a pistol with a rotary drive according to the preamble of claim 1.
  • Pistols with a turn are known per se, but not very widespread. On the one hand, they are considered to be particularly quiet-shooting and therefore desirable because the barrel performs a movement only about its axis or the axis of the soul, for example, when tilting pistols, the center of gravity of the barrel performs a vertical movement, in addition to a rotational movement about a transverse axis Weapon comes, which makes the weapon uneasy. On the other hand, since the necessary components for carrying out and limiting the rotational movement are subjected to the toughest of stresses and suffer heavy wear, which in practice always leads to problems in the reliability of such weapons, pistols with rotary motion have not really prevailed.
  • In contrast, pistols with Kipplauf are millions of times, it is in this context, for example, on the US 4,539,889 , the US 4,825,744 and the US 4,893,546 referred, which describe such weapons in detail. The content of these references is made to the jurisdictions in which this is possible by reference to the content of the present application.
  • There is thus a need to provide a revolving pistol which does not have the disadvantages mentioned, but which is as robust and reliable as a pistol with a tilting barrel and yet has the advantages associated with the revolver.
  • It is an object of the invention to provide such a weapon.
  • According to the invention, these objects are achieved by a weapon having the features specified in the characterizing part of claim 1. In other words, it is the barrel positively guided both in its longitudinal movement along the axis of the soul, as well as in its rotational movement about the axis of the soul over the entire length of the movement, it is particularly significant that when engaging the beginning of the Rotary movement of the barrel is caused by the interaction of control surfaces on the barrel and carriage. Through this durable, positive leadership to reach the mechanical stability and thus the reliability that has lacked such weapons in the prior art.
  • The invention will be explained in more detail below with reference to the drawing. It shows or show on the basis of an embodiment

  1. a) is a schematic bottom view of the carriage with parts of the frame, with
  2. b) a side view of the carriage, with
  3. c) a section normal to the axis of the soul at the position shown in b) and with
  4. d) shows a plan view of the carriage with a torn, front area.
  • In the specification and claims, the terms "front", "rear", "top", "bottom" and so on are used in the common form and with reference to a pistol held in a conventional manner. This means that the mouth of the barrel is "forward", that the shutter or carriage is moved by the explosion gases to the "back", etc ..
  • The Fig. 15 shows for guidance a pistol according to the invention in plan view (15a) and, schematically, in section through the plane of symmetry (15b). The term "plane of symmetry" is understood to be technical and not mathematical, since various components are not formed symmetrically to this level, but the essential and the entire appearance.
  • A weapon 1 has a frame 2, which, in one piece or built, also includes a handle in which a magazine is inserted. The illustration of the magazine spring shows that the cut is made schematically and not strictly geometrically. In the carriage 3, a firing pin and in the frame 2 a trigger mechanism are shown. All of this is state of the art and needs no further explanation. A barrel 4 is stored in the closure (slide) 3, as will be described below.
  • The Fig. 1 shows the situation immediately before the delivery of the shot. Fig. 1a is a bottom view of barrel 4 and slide with the part of the frame 2, which carries a control groove 9: longitudinally movable on the frame 2, the closure 3 is provided, in which the firing pin, together with any (n) backup (s) and holding mechanisms, as in the state The frame 2 carries the shutter 3 with the barrel 4 and the return spring 5 and other components, as is also known from the prior art. It is in this context to the cited documents and the Fig. 15 directed.
  • Between the barrel 4 and the closure 3 or the frame 2, the following geometrical and therefore also dynamic features are provided (also in FIGS Figs. 12-14 In the illustrated embodiment, the barrel 4 has two locking lugs 6, which are formed projecting in the radial direction and in the locked state, like the Fig. 1 shows him in locking grooves 7 ( Fig. 3d ) of the closure 3 and thus fixed in the axial direction, which also fixes the barrel with respect to the closure in the axial direction. These locking warts are formed differently from each other for reasons explained below and as can be seen from the illustrations d), but this does not affect the effectiveness of both warts in terms of the axial fixation of the barrel.
  • The term "axial direction" is understood to mean the direction of the axis of rotation or axis of the shaft 10, which is to be regarded as frame-fixed for the purposes of the description.
  • Furthermore, the barrel 4 has a control cam 8 which projects into a cam groove 9 of the frame 2 (not the shutter 3!). This control groove 9 has an oblique, central, region, at the one, the front, the end of an axially projecting locking region connects, in which in. In Fig. 1 shown position the control cam 8 is located. The control cam 8 can be moved in the locking area a small distance in the direction of the axis of the soul 10. The control groove 9 has at the other, the rear end on a holding area, the function of which will be explained below. Here, it should only be pointed out that the holding area at the front has a holding surface 17 (which runs normal to the axis of the soul 10). Fig. 2 ) has formed.
  • Like a comparison of Fig. 1 with the Fig. 2 directly shows, the latter represents the situation shortly after the delivery of the shot, thus shortly after the in Fig. 1 Shown in the illustration shown, shutter 3 and barrel 4 move together, without relative movement to each other, a short distance, in the range of 1-3 mm in length, in the direction of the axis of the shaft 10 to the rear, so that shutter and barrel remain reliably closed until the projectile has left the barrel 4. This joint movement of the lock and barrel on the frame without rotation ends when the rear surface of the control cam 8 at the rear End of the locking portion of the cam 9 arrives, as in Fig. 2 shown. The comparison of Fig. 1d with the Fig. 2d further shows that in this time the angular position of the barrel 4 around the axis of the soul 10 remains unchanged. The rear wall of the control cam 8 in this case has the same inclination with respect to the axis of the soul 10 as the contour of the cam 9, so that it comes to a surface contact, which is the impact forces to endure in the best possible way.
  • The Fig. 3 , shortly after the Fig. 2 lying, now shows the rotational movement, which forces the cam 9 in the frame 2 on the control cam 8 on the barrel 4 in the course of the common backward movement of the carriage together with the latter. This is clear on average Fig. 3d to recognize the locking lugs 6 are already completely out of the locking grooves 7 of the closure passes, run 4 and 3 are not connected in the axial direction.
  • This situation is in the Figs. 4e and 4f , a perspective view and an enlarged detail, easy to recognize. By this rotational movement in the extent shown, the axial connection between the shutter 3 and 4 barrel is released.
  • The final rotational position is in Fig. 5 (Temporarily after Fig. 4 The two locking lugs 6 have not only come completely out of the locking grooves of the closure 3, but now lie in the region of longitudinal guides 19 which are formed on the carriage 3, as in FIG Figs. 4f . 5d and 6d good to see. In the further axial movement, now separated by carriage and barrel, so the angular position, with play (maximum 8 °, preferably at most about 5 °, more preferably at most 4 °) secured around the axis of the soul.
  • It should also be noted that the lateral surface of the control cam 8 (parallel to the axis of the soul 10) is terminated by their contact with the lateral surface of the cam 9, the rotational movement of the barrel 4, leads to a flat contact, thus creating stable mechanical conditions. It should also be noted that the front surface of the control cam 8, which is normal to the axis of the soul 10, in this position a small distance from the support surface 17 (also Fig. 1 ), which means that the barrel 4 has a certain axial play with respect to the frame 2 in this position.
  • The Fig. 6 shows the time following situation with the carriage 3 as far back as possible at the end of the return: The barrel 4 is fixed by the control cam 8 and the control groove 9 with respect to the frame 2 (with the mentioned game), while the shutter 3 by the pressure of the explosion gases and the Thus brought initial pulse and the inertia is further brought to the rear, in its rearmost position: The barrel 4 protrudes in the axial direction far out of the shutter 3. The Fig. 7 shows the same situation as the Fig. 6 , only at the beginning of the flow of the shutter 3, otherwise there is nothing additional to say.
  • As a result, by the return spring 5 ( Fig. 15 ), the carriage 3 brought back to the front, the movements proceed as explained below, until finally the in Fig. 1 shown situation is reached again.
  • The Figs. 8a -8d show the engagement, the closure is compared to Fig. 7 has already reached far forward, the rotation of the barrel 4 has just begun, as the 8d shows:
    • A peculiarity of the invention lies in the fact that when the closure (when feeding a cartridge), the control cam 8 of the barrel 4 is pressed onto the holding surface 17 of the cam 9 (in frame 2), which is normal to the axis of the soul 10, whereby the rotational movement of the barrel 4 is not effected by this, with tolerated interaction, but by the interaction of the contact surface 18 of the associated locking lug 6 of the barrel 4 with the guide rail-like abutment surface 11 (see especially in Fig. 8c and Fig. 13b ) is introduced in the closure 3.
  • The Fig. 13b , A bottom view of the closure 3 with only partially inserted barrel 4, shows the stop surface 11 of the closure in its entirety. It is on the inner surface of the upper wall of the closure as an increase, thus inwardly projecting towards the soul axis 10, formed and cooperates with the in the various representations "d" upwardly projecting locking lug 6 together.
  • It is therefore the beginning of the rotational movement of the barrel by this control surface causes the abutment surface 11, which is much more accurate with respect to the barrel than any possible component which would be provided fixed to the frame 2. For this reason, and by matching the shape of the associated locking lug 6 on the shape of the stop surface 11, there is a reliable and mechanically stable leadership that shows no significant wear over the life of the weapon.
  • This particular shape of the associated locking lug 6 consists essentially in that the forward direction of rotation in the front face, the guide surface 18, in its inclination with respect to the axis of the axis coincides with the inclination of the stop surface 11, so that it comes to a two-dimensional contact. Thus, the static pressures and the dynamic loads compared to those that occur in the art, reduced by orders of magnitude.
  • During the advance thus the initiation of the rotation takes place via surface contacting of components which are equipped and guided with small tolerances to each other, and not via a linear contact between components, which are essentially only indirectly, via the carriage 3, very inaccurate to each other, as is the case in the prior art.
  • Only after this initiation of the rotational movement is the further and complete locking of the barrel in the closure by the control cam 8 in cooperation with the cam 9 in the frame 2, as shown in Fig. 10 evident.
  • After this complete lock the two components, shutter 3 and barrel 4, the above-mentioned short axial distance in the control groove 9 together and already locked together in the direction of the axis of the shaft 10 on the frame 2 forward, as in Fig. 11 shown.
  • Due to the invention initiation of the beginning of the locking of the barrel by initiating the rotational movement not by the control cam 8 (control cam) in cooperation with the frame 2, but by the control surface 18 and a ramp surface, the stop surface 11, between the shutter and barrel this movement completely defined and, judging by the circumstances, bumpless and initiated by two-dimensional contact. In addition, the pilot cam-to-cam timing is mechanically much more compatible than is possible in the prior art, thus ensuring the reliability and long life previously unrivaled in rotary guns.
  • An embodiment of the invention, which further increases the mechanical stability, can be seen from a synopsis of the individual representations "d". The closure 2 has in the axial region between the locking grooves 7 and the thrust plate 13 (FIG. Fig. 15 ), preferably adjacent to the locking grooves 7, has a shape which surrounds the barrel beyond its diameter and thus forms a positive-locking guide with the retaining aperture 14 for travel in the front face of the closure (albeit with a noticeable play in the range of 0.05 to 0.1 mm deviation from the ideal position in each direction) for the barrel 4 in the axial direction. Thus, the correct relative position of the contact surfaces of the locking lug 6 and the abutment surface 11 is best ensured, as well as the quiet movement of the carriage and the barrel when firing a shot.
  • Especially the Fig. 13 shows the formation of the carriage 3 in a circular shape with enveloping surfaces 16 which extend over the axial plane 15 (quasi equatorial plane) away, whereby the barrel 4 is prevented from tilting; only the axial displacement and the rotation about the axis of the soul 10 are through these hollow cylindrical envelope surfaces 16 ( Fig. 12b and, without reference numerals, Fig. 9d ) of the lock.
  • From the Figs. 12 to 14 the assembly of such a closure is clear, with the return spring 5 is not shown for reasons of clarity: The barrel 4 is inserted with its front end through the retaining hole 14 of the closure and pushed obliquely so far forward that its rear end in front of the envelope surfaces 16 to come to rest. He is so twisted that the locking lug, which carries the contact surface for the rotational movement, protrudes away from the frame and is located almost in the weapon center plane. In this situation can, like the Fig. 13 shows, the barrel can be pivoted into its operating position, and in this position, he can be moved backwards to the shock bottom, causing its rear part (but at this Movement is front!) In the area of the enveloping surfaces 16 comes and so, as described above, is performed. Fig. 14 shows the end position in which the (not visible here) contact surfaces on wart and closure have already carried out the beginning of twisting, locking lugs and locking grooves face each other.
  • The invention is not limited to the illustrated and described embodiment, but can be modified variously. Thus, it is possible to give the warts and grooves different shape and / or dimension, their position relative to the frame, the closure and the barrel may be different than shown.
  • It is essential in the preliminary run that the start of the rotational movement of the barrel with respect to the carriage takes place through the contact of a stop surface located on the closure on the one hand and a counter surface located on the barrel on the other hand. In this case, one of the surfaces is preferred, but not necessarily, provided on one of the locking lugs, since these must be present anyway. The surface on the closure is, because of a symmetrical introduction of force, preferably arranged in the region opposite to the frame, thus substantially in the plane of symmetry of the weapon in the upper, inner wall region of the closure.
  • It can also be designed so that they do not interact with the two locking lugs but with one of the locking lugs and the control lobe the leadership of the barrel through the longitudinal guides 19.
  • The materials to be used are the same as conventional guns and need no further discussion here, as well as the manufacturing processes and other technological details.
  • In summary, it can thus be stated that the invention relates to a pistol 1 with a frame 2, a closure 3 movable thereon and a revolving loop 4 located in the closure. The rotation is rotated by cams and grooves with respect to the closure between a locked position and an open position and moved axially.
  • In order to avoid the usual wear in such weapons wear is provided that the shutter 3 has an obliquely to the axis of gravity extending stop surface 11, and the barrel a corresponding contact surface 18. When locking is the flat contact between these surfaces 11, 18, the beginning of the relative Rotation initiated.
