Definitions
- the invention relates to a pistol with a frame, a barrel, a slide which can be moved along the frame and a return device which is arranged between the frame and the slide and urges the slide into its front position.
- Such pistols are known in a large number of technical variants and configurations. Common features in such pistols are: a fixed or movable barrel, a grip part, a magazine and a slide.
- the lock is defined between the barrel and the slide.
- the carriage can be displaced on the handle part in a direction which corresponds at least approximately to the direction of travel. The sleeve of the last fired cartridge is pulled out of the breech by the movement of the carriage and the next cartridge is loaded from the magazine into the breech.
- the movement of the carriage takes place after a shot has been fired by the pulse in the breech, and after a return device has reached the rear end point of the movement to the front.
- the return device usually consists of a coil spring and is arranged below or around the barrel. It essentially takes up its entire length in order to be able to apply the force required to move the slide over the required length of movement of the slide.
- the carriage must move over a length that allows the sleeve to be removed and the next cartridge to be inserted. With the necessary spacing in the axial direction, the carriage movement must be at least significantly longer than the length of the cartridges. It has been around for some time, especially among professional users of pistols, such as police officers, gendarmes, members of the security services and the like. the desire to make the weapons as compact as possible without having to resort to small calibres.
- the return device was broken up into two individual springs which are arranged on the left and right of the slide. This arrangement makes the weapon very wide, so that the carrying and handling comfort is impaired and requires extensive constructive measures in the covering and guiding of the springs. In addition, the maintenance and disassembly of the weapon is more complicated than with the weapons with the return device under the barrel.
- buffer devices are also used for the breech in various ways in order to prevent the breech from hitting the frame parts too hard under the action of the propellant gases. The issue of shortening the barrel does not matter.
- Such a device is known from DE-A 21 11 126 and has a radially deformable squeeze body which is rubbed against the force of two coaxial springs on a cylindrical inner wall upon impact of the closure and thus brakes the closure.
- the squeeze body When the closure is brought forward by the return spring, the squeeze body is also brought back into its foremost position under the action of the two coaxial springs.
- Two springs are only provided to increase the spring force.
- the invention aims to provide a pistol of the type mentioned with a further shortened barrel while still arranging the return device under the barrel.
- the return device has at least one outer spring and one inner spring and a connecting sleeve arranged between them.
- the working paths of the individual springs are added to the working path of the return device.
- the return device has at least two helical springs which have different diameters and are arranged telescopically one inside the other, with a connecting sleeve being arranged between them and having a shoulder at each of its ends, with one end of each of the springs on each is present.
- the two springs are essentially pushed into one another. In this starting position, a pretension is necessary in order to press the carriage firmly and reliably into its foremost position and to hold it in it.
- FIG. 1 shows a pistol according to the invention with a return device in its pretensioned starting position
- FIG. 2 shows the pistol according to FIG. 1 in the position in which the carriage takes its rearmost position.
- a pistol according to the invention is shown in section along its plane of symmetry.
- a frame 1 can be seen, which also comprises a trigger guard around the trigger 2, a barrel 3 and the front part of a slide 4.
- the prestressed starting position of the return device 5 is shown.
- the return device is arranged between the frame 1 and the carriage 4 and exerts a force on these two components which tends to bring the carriage 4 into the foremost position shown in FIG. 1. In this state, the pistol is ready to fire when a cartridge is in the breech.
- the return device has two helical springs: an inner spring 7 which is supported at one end on an end face of the frame 1 and at the other end on an inner collar 12 of a connecting sleeve 8 and an outer spring 6 which is in contact with one another with one end supported on a collar of the slide 4 and with its other end on an outer collar 11 of the connecting sleeve 8.
- the two springs are of different lengths and the connecting sleeve 8 determines the length of the shorter spring in the starting position.
- a guide 9 in the form of a tube or rod is provided within the turns of the inner spring 7 in a known manner.
- Fig. 2 the carriage and the return device are shown in the rearmost position of the carriage.
- the inner spring 7 is compressed in such a way that its individual turns touch each other, overstress is prevented by a corresponding length dimensioning of the connecting sleeve 8.
- the outer spring 6 is also compressed until the individual turns come into contact, the stop 10 of the slide 4 on the frame 1 prevents its overstressing. Add to that both springs in the state the compression is carried out both inside and outside, so that the danger of winds colliding or buckling has been countered.
- the invention can be modified in many ways. It is thus possible to manufacture the springs from flat wire, so that the windings are in flat contact with one another in the case of compression. It is also possible to choose the length ratio or the ratio of the number of turns of the springs to one another differently from what is shown, taking into account the axial length by which the individual springs can be shortened (their working length) to achieve the required work path of the return device overall.
