Abstract

A portable firearm with quick coupling removable stock comprising a firearm body, provided with a grip, and a removable stock, which can be associated with the firearm body by means of a quick coupling device; the quick coupling device includes a hollow body, which is fixed to the firearm body, and an elongated body, which is integral with the stock and can be at least partially inserted in the hollow body; the device includes an interference member adapted to lock the elongated body in the hollow body in a locking position; the interference member is movable from the locking position to a release position in which the elongated body is movable and can be extracted from the hollow body. The interference member can be actuated easily by using a component of the firearm itself as a tool.

Claims

1. A portable firearm with a quick coupling removable stock, said firearm comprising a firearm body, provided with a grip, and a removable stock, which can be associated with said firearm body by means of a quick coupling device, said firearm having a cocking handle with a stem;

said quick coupling device comprising a hollow body, which is fixed to said firearm body, and an elongated body, which is integral with said stock and can be at least partially inserted in said hollow body;

said quick coupling device further comprising an interference member adapted to lock said elongated body in said hollow body in a locking position, said interference member comprising a piston which moves in opposition to a force exerted by a contrast or compression spring in a seat formed in said elongated body, said piston having an end adapted to engage a hole formed in said hollow body, in said locking position said contrast or compression spring pushing said piston into a position for engaging said end in said hole of said hollow body, thereby preventing the movement of said elongated body in said hollow body;

said interference member being movable from said locking position to a release position in which said elongated body is movable and can be extracted from said hollow body, said release position being obtainable by pressing on said end of said piston, overcoming the force of said contrast or compression spring and disengaging said end from said hole, thereby allowing a sliding of said elongated body in said hollow body and a disconnecting of said stock from said firearm body, said end of said piston having a recess configured to accommodate a tip of said stem of the cocking handle for disengaging said end of said piston from said hole.

2. A portable firearm with quick coupling removable stock, said firearm comprising a firearm body, provided with a grip, and a removable stock, which can be associated with said firearm body by means of a quick coupling device;

said quick coupling device comprising a hollow body, which is fixed to said firearm body, and an elongated body, which is integral with said stock and can be at least partially inserted in said hollow body;

said quick coupling device further comprising an interference member adapted to lock said elongated body in said hollow body in a locking position, wherein said elongated body is telescopic and is constituted by a tubular body and by a central body that can slide in said tubular body;

said central body being fixed in said tubular body in different positions by means of a series of screws that can engage in seats formed in said central body.

3. The firearm according to claim 2, wherein said interference member comprises a piston which moves in opposition to a force exerted by a contrast or compression spring in a seat formed in said elongated body.

4. The firearm according to claim 3, wherein said piston is provided with an end adapted to engage a hole formed in said hollow body.

5. The firearm according to claim 4, wherein, in said locking position, said contrast or compression spring pushes said piston into a position for engaging said end in said hole of said hollow body, preventing the movement of said elongated body in said hollow body.

6. The firearm according to claim 5, wherein said release position is obtained by pressing on said end of said piston, overcoming the force of said contrast or compression spring and disengaging said end from said hole, thereby allowing a sliding of said elongated body in said hollow body and a disconnecting of said stock from said firearm body.

7. The firearm according to claim 6, wherein said firearm had a cocking handle with a stem and wherein said end of said piston has a recess that is configured to accommodate a tip of said stem of the cocking handle.
