Definitions

• the invention relates to a pistol consisting of a basic housing and a sliding carriage guided thereon, which in cross section consists of two side walls and a cover wall in between, inside which sliding carriage a barrel is guided in front and an insert containing a firing pin and a striker spring is fastened behind it.
• the impact energy required to trigger the shot is applied to the firing pin by an impact spring housed inside the barrel.
• the space conditions are correspondingly narrow in the design of firing pin and firing spring.
• both parts are concentric, either the spring surrounds the striker, or the spring is accommodated in a quiver-like, extended quiver, and the entire assembly is inserted from behind into a long longitudinal bore in the insert.
• the disadvantage of these designs is that the above
• Assembly consists of very complicated parts that are very complex to manufacture and assemble. Due to the small diameter available, the striking spring is too slim, it kinks a little and rubs on the edge surfaces, either of the quiver or the hole in the insert, which has no smooth wall due to its length (unless it is costly to rework inside).
• the fact that the hole is drilled into the insert from the rear means that the assembly of the assembly in the insert and the insert in the slide is delicate in view of the bumps when firing. Their lifespan is limited.
• the available overall length of the assembly limits the spring force and thus also the impact force. This can lead to ignition problems. In the future, this problem will be more pronounced due to the more and more legally prescribed low-emission squibs, which require higher impact energy.
• the insert forms an interior on the side facing the top wall of the sliding carriage, an open cavity in which guide surfaces are provided for the firing pin
• the firing pin has mating surfaces lying on the guide surfaces of the cavity and on its side facing the top wall of the slide between the firing pin and the top wall leaves a longitudinal space
• the free space contains the striking spring, the front end of which rests on the firing pin and the rear end thereof is supported on an abutment.
• the insert is easy to machine (no more deep drilling!) And offers plenty of space inside for firing pin and striker, which is simply inserted into the cavity from above before the insert is installed.
• the insert has the shape of a trough, the rear wall of which can be connected to the sliding carriage in a way that it is resistant to impact, which benefits the service life.
• the guide surfaces can be simple surfaces, which allows clean guidance with little manufacturing effort.
• the recess on the top of the firing pin for receiving the firing spring does not need to be concentric with the tip of the firing pin, also thanks to the good guidance in the insert.
• the end walls that delimit the front and rear recesses can be very far apart, so that there is more space for the striking spring in the longitudinal direction as well.
• the spring can not only be dimensioned stronger, it is also less hindered in its movement.
• the cross section of the firing pin and thus also that of the free space, can be designed very freely within the scope of the invention. In the extreme case, it is so wide that the free space on the side is limited to the Longitudinal walls of the insert is limited. In another
• the recess is a longitudinal groove open at the top.
• the spring is surrounded on all sides by surfaces despite its mostly eccentric position, but with enough distance. Both the longitudinal wall of the insert and the groove can be machined easily and cheaply with high accuracy, for example by milling.
• the guide surfaces in the insert and the counter surfaces of the firing pin form the three sides of a rectangle.
• the entire firing pin is a cuboid body in its basic form and can therefore be easily machined.
• the formwork bolt is secured against twisting and its mass, and thus the possible impact energy, can be increased
• the rear wall of the box-shaped insert piece forms the abutment for the rear end of the striking spring and lies against the rear end of the slide.
• the former means that there is no need for a separate abutment or screw connection for the assembly. The latter increases the resistance to bumping and thus the service life.
• the insert is connected to the running carriage at two points by means of horizontal pins or the like, which pins penetrate the entire width of the running carriage.
• the pin can penetrate the rear wall of the insert at the rear connection point.
• the rear wall of the insert has a transverse groove for the insertion of the Kimme, for which purpose it is thickened in the upper part in the longitudinal direction of the gun.
• the rear sight can even be formed in one piece with it on the rear wall of the insert.
• the rear sight can be arranged very deep with respect to the barrel axis, which makes sighting easier and helps to achieve better hit results.
• the manufacturing costs and the number of parts are further reduced.
• FIG. 2 shows a top view according to II in FIG. 1
• FIG. 3 shows a cross section according to III-III in FIG. 1
• FIG. 4 like FIG. 3, but in a variant
• FIG. 5 like FIG. 1 in another 6 shows a cross section according to III-III in FIG. 5, FIG. 7 as in FIG. 1, in yet another variant.
• Fig. 1 the basic housing 1 is only hinted at.
• a carriage 2 is slidably guided in a known manner. You can only see the rear part of it, its cross-section (Fig. 3) is approximately U-shaped and consists of two side walls 3, 4 and 5 see a top wall 5.
• the top wall 5 of the carriage 2 has an opening 6 approximately in the middle of its length and ends at the rear on an end surface 7.
• An insert 8 10 is fastened on the inside in the rear part of the carriage 2. It is trough-like and has two side walls 9, 10, a base 11 with a slot 12, an end wall 13 at the front and a rear wall forming an abutment 14. A high space 15 is thus formed in the interior of the insert 8 and has guide surfaces 16, 17 and 18 which (see FIG. 3 and even better in FIG. 4) 15 are the three sides of a rectangle in cross section.
• the insert 8 is firmly connected to the carriage 2 by means of shear pins 29, 30.
• the pins 29, 30 or the like penetrate the side walls 3, 4 of the carriage and the end wall 13 or the rear wall 14 of the insert 8.
• the two shear pins 29, 20 30 at a great distance from one another serve to fasten the insert 8 in the carriage 2. This attachment and the abutment of the rear wall 14 on the end face 7 of the carriage 2 result in a shockproof and durable connection.
• a firing pin 20 is arranged to be displaceable in the longitudinal direction. It is an approximately cuboid body which has the actual striking pin 22 at the front and a flag 21 projecting downward through the slot 12 at the rear, which is connected to a trigger device (not shown).
• the firing pin 20 has counter surfaces 26, 27, 28 which, together with the guide surfaces 16, 17, 18 of the insert 8, form a precise longitudinal guide. Furthermore, the firing pin 20 has in its front part an open back shoulder 23, of which from up to the rear end of the firing pin 20 a free space
• This free space 24 is delimited here laterally by the side walls 9, 10 of the insert 8, at the bottom by the body of the firing pin 20 and at the top by the top wall 5 of the carriage 2. To the rear it extends to the abutment 14.
• a striking spring 33 is accommodated in this free space, which is rectangular in the exemplary embodiment shown.
• the front end 34 is supported on the shoulder 23 and the rear end 35 of the abutment 14. It can be seen how much space is available in the construction according to the invention for accommodating a generously dimensioned impact spring 33.
• the variant of FIG. 4 differs from that of FIG. 3 in that the insert 108 has a larger cavity 115 for receiving a more massive firing pin 20.
• This firing pin fulfills the entire height of the insert 8 approximately up to the top wall 105.
• the free space for the striking spring 33 is here a groove 130 which is milled into the firing pin. Simple and easy-to-manufacture parts are used in both variants. Assembly is also easy: firing pin and
• Impact springs are inserted into the insert, then the insert is inserted into the carriage from below and fastened by means of the shear pins.
• the rear wall 14 of the insert 8 is thickened in the longitudinal direction and the top wall 5 of the carriage 2 is shortened accordingly.
• a rear sight is formed in one piece with the upper part of the insert 8. As in Fig. 6, it rises just above the silhouette of the slide, so it is very close to the barrel axis.
• a dovetail groove 50 is provided at the same point on the insert 8 for inserting a rear sight 51 (indicated by dashed lines).
