Definitions
- the invention relates to the field of firearms and more particularly to a pistol.
- the main stresses obtained when unlocking, via the axis or at least one ramp of the same name, tend to raise and generate a significant bending of the chassis which transmits these strong mechanical stresses to the rear part of the chassis via the support. .
- the amplitude of these mechanical stresses is sufficient to cause fatigue cracks in the frame.
- the object of the invention is to overcome at least one of the drawbacks of the above-mentioned state of the art. More particularly, the object of the invention is to improve the mechanical strength of the weapon.
- the invention may also relate to a pistol comprising: a synthetic material carcass having a channel formed inside the carcass, said carcass comprising a handle disposed below said channel; a barrel slide guided in a longitudinal direction of the carcass, said slide comprising a barrel and a breech; a trigger mechanism; a preferably one-piece frame having an elongated shape extending from a central portion of said carcass to a rear end of the carcass, in particular ensuring the maintenance and / or guiding of the movable elements of the trigger mechanism, said frame further comprising guide elements for guiding the barrel slide, the gun being such that the channel is designed to removably receive the frame and that the frame includes a slide disassembly pin rotatably mounted in the frame , characterized in that the axis for removing the slide is not in contact with the carcass.

- the shape of the ramp 24 and the positioning of the unlocking axis 20 are chosen to ensure tilting of the barrel.
- the tilting of the barrel 22 makes it possible to facilitate the feeding of a cartridge following the lowering of the barrel 22 towards the lips of the magazine.
- an unlocking pin 20 is proposed.
- other means can be envisaged for inducing the tilting of the barrel such as, for example, lugs formed on the internal side walls facing the frame 4.
- the unlocking pin 20 or, the equivalent means and the frame 4 can form a single piece (monobloc).
- the dismantling function and the unlocking function are provided by the same axis called unlocking and dismantling. It is nevertheless obvious to those skilled in the art that these two functions can be performed by distinct elements. This is in particular the case when the unlocking element and the frame are formed in one piece (monobloc).
- the figure 4a also illustrates rear 42 and front 44 guide elements for the barrel slide 22.
- the figure 4b shows the rear part of the barrel 22 and the frame 4 at the top where the unlocking axis 20 is impacted by the or each an unlocking ramp 24 of the barrel 22.

This configuration makes it possible not to transfer torque resulting from the unlocking force by the shaped connection ensuring homogenization of the resulting stresses.
- the first unlocking means 24 can comprise two unlocking ramps 24 positioned on either side of the median plane of the gun.
- the or each unlocking ramp 24 may be formed by a portion of an edge of an orifice (for example in the form of a bean), a notch or an arm formed at the rear of the barrel 22.

- the female part of the form connection is formed at the front end of the frame 4 so that the forces associated with firing cycles (eg unlocking) are transmitted directly to the carcass via the form link by "bypassing" the central and rear part of the frame 4.
- the carcass 2 may include, at the level of the form connection, extra thicknesses at the level of the lateral flanks of the channel 6 in order to reduce the constraints linked to the transfer of the firing forces.
- the partitions (branches) 16A, 16B are preferably connected at least at the level of a front part of the frame 4, at the front of the loading area, by a barrel dismantling pin ( figure 2 ).

More specifically, this interface includes a part the vertical component of the forces linked to the firing cycles (for example the rear stop force of the barrel).

De manière générale, les modes avantageux de chaque objet de l'invention sont également applicables aux autres objets de l'invention. Dans la mesure du possible, chaque objet de l'invention est combinable aux autres objets. Les objets de l'invention sont également combinables aux modes de réalisation de la description, qui en plus sont combinables entre eux.In general, the advantageous modes of each subject of the invention are also applicable to the other subjects of the invention. As far as possible, each object of the invention can be combined with other objects. The subjects of the invention can also be combined with the embodiments of the description, which in addition can be combined with one another.
Les mesures de l'invention sont intéressantes en ce qu'elles permettent à résistance mécanique égale de limiter au mieux les sollicitations, et donc d'optimiser la géométrie générale du châssis. Par exemple, les branches du châssis qui lient la partie avant à la partie arrière peuvent être affinées. La fine épaisseur des branches du châssis ainsi obtenue permet un encombrement en largeur autour du chargeur assez fin, suffisant pour laisser la place à un chargeur sans déquinconcement, c.-à-d. fonctionnant sur un principe de double colonne jusqu'aux lèvres supérieures du chargeur. De surcroît, les mesures de l'invention permettent une localisation et un maintien des pièces de mise à feu dans une pièce métallique offrant moins de dispersions géométriques par rapport à une carcasse plastique et une flexibilité sur le design de la carcasse car celle-ci devient uniquement un élément de préhension beaucoup moins fonctionnel que l'état de l'art antérieur.The measures of the invention are advantageous in that they allow equal mechanical strength to best limit the stresses, and therefore to optimize the general geometry of the chassis. For example, the branches of the chassis which link the front part to the rear part can be slimmed down. The thin thickness of the branches of the frame thus obtained allows a space requirement in width around the loader that is thin enough, sufficient to make room for a loader without squashing, ie. operating on a double column principle up to the upper lips of the loader. In addition, the measures of the invention allow localization and maintenance of the firing parts in a metal part offering less geometric dispersions compared to a plastic carcass and flexibility in the design of the carcass because the latter becomes only a gripping element much less functional than the state of the prior art.
D'autres caractéristiques et avantages de la présente invention seront mieux compris à l'aide de la description et des dessins.Other features and advantages of the present invention will be better understood from the description and the drawings.
