Abstract
A pistol is provided, on the plastic housing of which a sliding carriage containing the barrel is guided in the longitudinal direction, which housing has a trigger guard at the transition to a grip stock, and in which housing a locking block is arranged; for an especially light embodiment that is simple to manufacture and nevertheless robust, the locking block forms a unit with the guiding elements of the sliding carriage, which unit is arranged in front of the magazine well and extends forward as far as the trigger guard, as a result of which the guide length is shortened. The locking block is fixed in the housing by a front cross pin and a rear cross pin and accommodates a locking bolt approximately over the second cross pin.

DETAILED DESCRIPTION
(10) In FIG. 1, a pistol housing consisting of plastic is identified with 1, the grip stock thereof is identified with 2 and the trigger guard thereof is identified with 3. A sliding carriage 5, which accommodates a barrel 4, is guided on the housing 1 in the longitudinal direction. The housing-fixed guide elements 6 of said sliding carriage and corresponding guide grooves 7 in the sliding carriage 5 are only suggested here, because they are described in detail below; in the same manner as a locking block 8. The grip stock 2 includes a non-illustrated magazine compartment.
(11) Several details can be seen in FIG. 2. A space 11 for accommodating the unit consisting of the locking block 8 and the guide elements 6, 6, which are separate here, is present in the housing 1 behind a stop 10 for the sliding carriage 5. Together, they take up the entire width of the space 11. This unit is fixed in the housing 1 by means of cross pins 12, 13, which extend through bores 14, 15 and 16. The length of the locking block 8 is approximately identical to the length of the trigger guard 3. In front of it, there is room for a non-illustrated return spring. A locking bolt 17 is transversely located in bores 18 in the side walls 20 of the locking block 8 at right angles. Said locking block cooperates in the known manner with a lug 19 on the underside of the barrel 4. A depression as clearance 21 for the lug 19 is located between the side walls 20. The guide elements 6 are plates 6 which abut on the locking block 8 on the one side and on the inner walls of the housing 1 on the other side.
(12) FIG. 3 shows such a guide element 6 or plate 6, respectively, in an enlarged manner. It is a stamped part of a flat basic shape of a very hard or hardened plate having, on its upper edge, a first (23) and a second (24) claw 23, 24, which is bent outwards at a right angle. These claws 23, 24 engage with guide grooves 7 of the sliding carriage 5. To be fastened in the housing 1, the cross pins 12, 13 extend through the bores 15, 16. Smaller bores 22 accommodate ends of the locking bolt 17.
(13) As alternative, FIG. 4 shows a tab 25 which is directed upward between the two claws 23, 24 and which can provide an additional lateral guide in cooperation with the inner walls of the sliding carriage 5.
(14) FIG. 5 shows the locking block 8 with all details. The guide elements or plates 6, respectively, and 6, respectively, could simply abut on the outer wall of the locking block 8. However, they are inserted with a positive fit into recesses 31 in the side walls of the locking block 8 here. The guide plates 6 or 6, respectively, are embodied here as angle plates having a vertical leg 32 and a horizontal leg 33. The locking block 8 can thus take up the full width of the room 11 in the housing 1. More room is also available for further functional installations in the interior of the locking block 8. These functional installations could be, e.g., a non-illustrated trigger mechanism having springs and a carriage catch lever. Only one functional bore 30 can be seen in FIG. 5. A clearance 21, which ends with the rear at a rear wall 26, is located between the side walls 20. The locking bolt 17 is supported on this rear wall 26.
(15) The sliding carriage 5 with its guide grooves 7 can be seen in FIGS. 6, 7 and 8. In its basic shape, it is a hollow cuboid having side walls 34 and a cover wall 35, which is interrupted by an ejection window 36. It ends in the front in spectacles 37 and includes a non-illustrated striking mechanism in its rear half. The guide grooves 7 are milled out close to the lower edge of the side wall 34. However, they do not extend across the entire length of the sliding carriage 5, as usual, wherein the sliding carriage 5 is inserted into the guide in the longitudinal direction. Thanks to the described claws 23, 24, which are arranged in accordance with the invention (see also FIGS. 3, 4 and 5), it is sufficient, when the guide grooves 7 extend only along slightly more than the front half of the sliding carriage 5.
(16) For the purpose of assembly, apertures 38, 39 are provided in the guide grooves 7, see FIGS. 6, 7 and 8. The distance 40 between the apertures 38, 39 is equal to the distance between the claws 23, 24 of the housing-fixed guide elements 6. The position of the apertures 38, 39 determines an assembly position, in which the sliding carriage 5 is simply placed onto the housing 1 with the guides 6. The sliding carriage 5 is then displaced rearward by the length of the claws 23, 24, into the operating position, in which it is held in such a way that it can no longer be displaced forward. The sliding carriage can be pushed forward again until it can be lifted off towards the top, only when a non-illustrated dismounting lever is activated.
