Definitions
- the invention relates to a fore-end made of plastic, on a handgun in terms of its barrel essentially is fixed in position, with at least one at least one threaded hole for fastening on the long sides an additional device is arranged.
- Fore stock is on many rifles, submachine guns, light machine guns and even pistols.
- Modern ordnance weapons usually have forearms made of plastic, the barrel and possibly the gas piston or a tube for the closing spring at least from below enclose here.
- These forearms always provide one Hand protection and are usually easy to remove and exchange for other fore-stems that are about Additional devices are adapted, e.g. with the US rifle M 16, whose Forend made of plastic against a metal forend is interchangeable, to the rifle grenade device M 203 is adapted.
- the attachment of such additional devices on the fore-end offers many advantages: is amazing the position of the fore-end in relation to the barrel at least determined as well as the position of the handle for Run.
- the attachment on the handle is a target optic but commonplace (such as the night vision device on the US rifle M 16).
- a special feature are the injected threaded bushings; on the one hand, they ensure a reliable hold of the additional device; secondly, that of the additional device (s) applied load over a relatively large Area distributed. This allows the plastic forend the loads brought in easily resist.
- the person skilled in the art can also use the Increase the wall thickness in the area of the threaded bushes locally and / or insert reinforcements in the plastic, for example Glass fibers, metal rails or the like ..
- that is Occurrence of shear forces minimized by a bracket could be introduced, and the additional device can possibly be on the fore-end and thus forces transmitted to the fore-end by friction.
- the self-locking property of the threaded bush (es) has the advantage that a screw inserted therein is not must be tightened excessively, what else might the Holding the threaded sleeve in the plastic could endanger.
- the additional device by means of at least one Screw into or into an associated threaded sleeve is screwed in from the outside, and by means of at least one additional bracket is firmly attached to the fore-end.
- the additional bracket (s) provide one Distribution of burdens.
- the Another bracket is another screw that fits into one further threaded bushing is screwed in, which is also in the fore-end is injected. Because these threaded bushings be injected with high accuracy in composite casting are their locations and therefore their mutual Distance precisely defined. This will introduce additional tensions in the fore-end as a result imprecise mutual distances between the threaded bushings excluded.
- the further Bracket advantageously a rivet, which the wall of the Enforced fore-end.
- a rivet ensures Pressing the additional device on the forend for one flat distribution of the introduced loads. Indeed If necessary, the wall thickness of the hand protection in the area to increase the rivet.
- the considerable size of the cross-sectional dimensions of the Picatinny rail allows their simple manufacture, for example as a precision casting, without post-processing; otherwise, will be significant Manufacturing tolerances added without the positional accuracy to affect. Ensure the transverse grooves in the rail a reliable fit of the attached devices in a variety of places without their jamming the latter is too heavily burdened by rail. Cheap production Materials such as plastic that do not have strength of steel can therefore be used easily become.
- Sufficient threaded bushes in the fore-end are preferred injected to him at the bottom as well as left and right respectively to be able to attach a rail, depending on how many devices have to be attached to the fore-end.
- the accessory or one of the accessories is a contact carrier.
- This contact carrier can be coupled to parts of the rifle, such as the Fuse or a separate switch that is within easy reach near the other controls of the rifle is. So it is possible to have one on a rail To attach headlights or infrared headlights, the is then connectable to the contact carrier. The press then a switch on the rifle or the release button the headlight. Even the power supply of a passive Night aiming device, a laser pointer, range finder or another electrical device is over one Contact carrier can be actuated.
- the invention provides a simple and inexpensive Means to make a handgun quickly, universally and according to individual wishes with additional devices equip.
- the forend or handguard is made in one piece Plastic main part 1 formed on the top of a hinged Cover 3 is put on.
- the main part 1 with opened Cover 3 is from the front over the barrel, gas sampling piece, Pushed gas cylinder and boom of a rifle, and then the cover is closed.
- the front of the main part 1 is closed by an attached lid 2.
- a secured one Cross pin (not shown) can have openings 5 (Fig. 2) enforce and is attached to the gas sampling piece.
- projections 7 and a recess 9 on the back of the main part 1 stand with complementary training in the housing of the rifle (not shown) engaged.
- a rail is similar in an illustration Fig. 2 shown, but with a different equipment.
- Near the front is a short rail 15 by means of a screw 10 and two rivets 17 attached together the short rail 15 the stop for receiving a headlight (not shown). Push through the rivets 17 the wall of the main part 1 cast in or at the Mounting holes drilled and fasten the short rail 15 on this permanently.
- the screw 10 serves in addition the power transmission also to fix the short rail assembly and before riveting and sits in one self-locking threaded bush 11.
- a contact carrier 19 attached, which is riveted or clamped and which only the weight of a plug-like contact slide has to record, the exact location is immaterial.
