An adapter piece for mounting weapon accessory parts on a handheld firearm and a handheld firearm with such an adapter piece are disclosed.
To mount accessory parts, e.g., bipods, lamps, sights, cameras and the like, quickly and repetitively accurately on handheld firearms, so-called Picatinny rails are often used. However, these generally standardized mounting rails or other suitable adapters are, as a rule, integrated into the weapon housing or stationarily attached on a front stock or on other parts of the weapon. As a result, these mounting devices are not very flexible and, in addition, cannot be easily mounted and dismounted.
At least some embodiments of the disclosure relate to an easily mountable and dismountable adapter piece and a handheld firearm comprising such an adapter piece which allows accessory parts to be flexibly and accurately mounted.
Other useful embodiments and advanced embodiments are also disclosed.
On the adapter piece according to the present invention, a fastening element for detachably attaching the main body to a front stock of a handheld firearm is disposed on the main body which is fitted with mounting elements. As a result, when required, the adapter piece can be easily mounted and can be rapidly dismounted as well. To be able to mount accessory parts, the adapter piece offers a specially adapted front stock extension, thereby allowing any handheld firearm thus equipped to be modularly adjusted to the given needs without great effort.
In an especially preferred embodiment of the invention, the fastening element comprises a fastening pin which can be inserted into an opening of the front stock.
A ball ratchet mechanism with spring-loaded ratchet balls for the ratchet mounting of the adapter piece on the front stock can be conveniently disposed on the fastening element. The ratchet balls which are preferably evenly distributed along the circumferential direction are advantageously disposed in the fastening pin. This type of ball ratchet mechanism ensures not only quick and simple mounting and dismounting, but also enables accurate positioning and protects the adapter piece from being inadvertently pulled out and twisted.
Versatile mounting on the main body can be achieved, e.g., by configuring the mounting elements in the form of Picatinny rails which are disposed on the lower surface and the two outside surfaces of the main body which has a U-shaped cross section. The mounting elements can also be Weaver rails or other similar fastening bases that are suitable to receive accessory parts.
To expand the range of applications of the adapter, a roof-shaped upper part with an additional Picatinny rail or other mounting elements can be disposed on the main body.
The upper part is preferably removably attached to the main body. To this end, on the outside surfaces of two downwardly projecting legs, the upper part can comprise guide rails, which extend in the longitudinal direction relative to the upper part and which are spaced apart by a recess, for reaching under rib-like guide members on the inside surfaces of two upwardly projecting rib-like members of the main body. Because of the removable attachment of the upper part, it is possible to attach the upper part after the main body has been mounted on the front stock. This allows the adapter part to be mounted on handheld firearms which have, e.g., an open sight (rear and front sight) or a silencer with a larger diameter, without requiring a size adjustment. In contrast, on an adapter piece with a fixedly mounted upper part, the passage opening would need to be appropriately adjusted, which requires a corresponding size. Because of the removable upper part, the adapter piece can instead be manufactured in a slender design for a large variety of weapons.
To affix the upper part precisely positioned and securely to the main body, a ball ratcheting mechanism with, e.g., pressure pins for engaging in depressions of the upper part can be disposed in the main body. The pressure pins are preferably disposed in the main body in such a manner that in the mounted position of the upper part, the center line of said pressure pins is staggered in the direction of the stop surfaces in the main body with respect to the center line of the depressions of the upper part which are configured in the form of tapered bores. As a result, the upper part is continually pressed upwardly and forwardly against the stop surfaces of the main body so that the upper part can be positioned repetitively accurately on the main body.
On its end lying opposite to the fastening pin, the fastening element can have a receiving part for a sling mount. The receiving part can be configured in such a manner that as said receiving part is activated, the ratchet balls disposed on the fastening pin are moved into a disengaged position, thereby making it possible for the ratchet mechanism to be disengaged.
The fastening element can be detachably attached to the main body. However, it can also be integrally formed in one piece with the main body.
The present invention also relates to a gun or another suitable handheld firearm fitted with such an adapter piece.
Additional features and advantages of the present invention follow from the description of a preferred practical example below based on the drawings. As can be seen

The roof-shaped upper part 5 is configured with two downwardly projecting legs 14. For weight reduction, the upper part 5 has lateral cutouts 15 as well. On its upper surface, the upper part comprises an upper mounting element 16 again configured in the form of a Picatinny rail 16 and having a longitudinal groove 11 and rectangular transverse grooves 12 spaced at regular intervals from each other so as to form tooth-like elevations 13.
The fastening element 6, which is shown separately in
The sling mount 22 can be part of an Allen key which can be inserted into an opening on the receiving part 20 of the pin-shaped fastening element 6 and detachably attached to the fastening element 6 by means of spring-loaded ratchet balls which engage in the bores 21. The sling mount 22 can also be inserted into the opening of the front stock 2 when the adapter piece 3 is being dismounted. The ball ratchet mechanism of the ratchet balls 19 can be released by means of the receiving part 20 which can be axially moved relative to the clamping area 17, thereby making it possible for the main body 4 to be removed from the front stock 2. In this manner, the sling mount 22 which is inserted in the receiving part 20 can serve as a release button for the ball ratchet mechanism of the pin-shaped fastening element 6. The fastening element 6 can be mounted in the main body 4 by means of spring clamping bolts 23 (seen in
