  • the insert part may preferably be formed or molded in one piece from plastic so that the shaped spring 125 is integrated into the insert part 123, for example as a plastic injection-molded part.
  • alternative forms of the insert part and its form spring 125 as well as different materials, for example metal or metal plastic composites are usable.
  • the form of spring 125 can be formed as a separate component and then attach to the insert 123 via suitable fasteners.
  • the insert part 123 can be fastened at the front upper end of the housing-side section 35 of the adapter 3 by means of transverse pins or transverse bolts, which can be sprung, for example, for easy assembly and disassembly.
  • the pins 149 (see Fig. 9a) penetrate with pin holes or passages 34 on the adapter 3 aligned pin holes or holes 147 on the insert part 123.
  • Above the pin holes or recesses 147 extends approximately centrally in the longitudinal direction of the insert a web 137, the two-sided recesses 135 limited production-related, to make the insert 123 easier to design.
  • an attachment 133 is provided, which extends approximately to the form of spring 125, is integrally formed and forms an abutment for the folding grain 41 at its top.
  • a bolt spring construction is provided for locking the folding grain in its erected and folded position.
  • the insert extends saddle-shaped and stepped in a rearwardly extending flat, approximately rectangular longitudinal section 141.
  • a longitudinally extending piston rod guide 169 for guiding the gas piston rod 159 is provided approximately in the center (see Fig. 9b, 10a and 11).
  • the gas piston rod guide 169 tapers to form an abutment 171 for supporting a gas piston rod spring 173 (compare FIGS. 9a, 10a and 11).
  • two guide lugs 143 for centering the insert and the gas piston rod guide 169 are arranged projecting in the direction of the housing 4.
  • the guide lugs 143 engage with the orientation recess 103 (compare FIGS. 6a and 6b) on the front side of the housing 4 above the tube receptacle 99.
  • the gas piston rod guide 169 with an extension of the gas piston rod guide 175 in the housing 4 center each other and are aligned.
  • Recesses 145 are provided on the underside of the insert part 123 as semicircular transverse grooves extending transversely to the insert part 123.
  • transverse screws 49 by means of tangential and / or transverse screws (see Fig. 1 1) penetrate the tangential pins or transverse screws 49 also the semicircular transverse grooves 145. In the case of transverse screws 49, these lie with their heads on one
  • Fig. 15d shows a cross-sectional view of the insert 123 from above, in section through the front spring-loaded transverse pin 149, which is biased by a coil spring 151 to the outside.
  • the front cross-loaded transverse bolt 149 can be mounted in its inserted position in the adapter housing 3.
  • Figures 16 and 17 show partial perspective views of the housing 4a. At the front upper end of the housing portion 4a, a base 96 is provided with counter-profile, over which the dovetail profile 109 is pushed during its assembly and then slides over the subsequent approximately rectangular recess 98.
  • FIGS. 16 and 17 instead of the integral non-locating counterprofile 97 from FIGS.
  • the non-locating counter-profile 177, 179 is provided as a separate part. This may be made of metal or metal plastic composite parts and fastened in a suitable manner in or on the housing 4a. Alternatively, this separate part can also be bonded to the housing 4.
  • the floating bearing counter-profile 177 here also includes a counter-profile for complementary engagement with the dovetail guide 109.
  • the contact surfaces of floating bearing Jacobpro file 177, 179 executed spherical to keep the contact surfaces and thus the mechanical transmission moments as low as possible.
  • the separate part 177 penetrates in each case two approximately V-shaped or wedge-like transverse grooves 179 which extend approximately centrally from the upper side over the entire width of the non-locating counter-profile 177.

Abstract

L'invention concerne un adaptateur (2) qui est conçu pour le montage d'au moins un dispositif supplémentaire (45) sur une arme à feu semi-automatique (1), qui s'étend dans le sens de la longueur de l'arme, et qui présente une partie côté canon (25) et une partie côté carter (35). L'adaptateur (3) est caractérisé en ce qu'il peut par une de ses deux parties (25 ; 35) être fixé à un dispositif de retenue (79, 89) au niveau du canon (19) ou au niveau du carter (4), et qu'il peut par son autre partie (25 ; 35) être monté mobile au moyen d'un guide mobile longitudinalement (96, 97, 109; 177, 179, 181) au niveau du carter (4) ou du canon (19). L'invention concerne également une arme à feu semi-automatique (1) comportant un adaptateur (3) selon un des revendications 1 à 19, un dispositif de retenue (79, 89) au niveau du canon (19) ou du carter (4) pour la fixation de l'adaptateur (3), ainsi qu'un palier libre au niveau du carter (4) ou du canon (19), conçu pour le guidage déplacement longitudinal de l'adaptateur (3).
