DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to the field of personal firearms.
SUMMARY OF THE INVENTION
Numerous personal firearms have already been proposed.
The main object of the present invention is to improve existing personal firearm systems.
A particular object of the present invention is to provide a novel personal firearm system of improved handiness, which can use projectiles of a wide variety, both respect to range and with respect to mode of action, and which makes it possible to use projectiles of large mass with a portable gun.
In a first aspect, the present invention achieves these objects by a personal firearm characterized by the fact that it comprises at least two launch barrels and damper means associated with at least a main barrel and adapted to limit the recoil force generated thereby on firing.
In a second aspect, the present invention achieves the above-specified objects by a firearm including means adapted to enable the firearm to be supported on the forearm of the user.
Description of the Prior Art
Document U.S. Pat. No. 3,854,231 (BROYLES) describes a twin barrel firearm system. That document proposes limiting the recoil effect by expelling a countercharge from the back of the gun while simultaneously ejecting a useful charge from the front. That document neither teaches nor suggests associating an anti-recoil damping system with the gun.
Document FR-A-2 697 881 relates to a friction damper. That document does not teach a multi-barrel firearm system.
Documents U.S. Pat. No. 1,599,008 (DIENER) and U.S. Pat. No. 4,197,666 (NG) relate to multi-barrel guns. However those documents do not suggest damper means in any way.
BRIEF DESCRIPTION OF THE DRAWINGS
Other characteristics, objects and advantages of the present invention appear on reading the following detailed description with reference to the accompanying drawings, given by way of non-limiting example, and in which:
FIG. 1 is a diagrammatic perspective view of a firearm system in accordance with the present invention carried beneath the forearm of a user;
FIG. 2 is a diagrammatic longitudinal axial section view of a firearm system in accordance with the present invention;
FIG. 3 is a cross-section view of the same firearm system in a section plane referenced III in FIG. 2;
FIG. 4 is a second cross-section view of the same firearm system of the invention in a section plane referenced IV in FIG. 2;
FIGS. 5, 6, and 7 are longitudinal axial section views of three different rounds in accordance with the present invention; and
FIG. 8 is a longitudinal axial section view of a damper system in accordance with the present invention.
FIG. 9 is a front view of FIG. 8.
DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
The personal firearm system in accordance with the present invention shown in the accompanying figures essentially comprises: forearm of a user;
By way of non-limiting example, the main barrel 300 may, for example, have a calibre of 40 mm and the small calibre secondary barrel 500 may have a calibre of 5.56 mm.
The support base 100 may be implemented in numerous variants. It is essentially constituted by a rigid structure. The rigid structure defines two parallel chambers or channels 110 and 120 respectively housing the main barrel 300 and the secondary barrel 500.
The support means 200 are placed essentially on the top surface 102 of the base 100. The support means 200 include a main handle 210 projecting from the top surface 102 of the base 100, e.g. substantially halfway therealong.
The main handle 210 is fitted with a firing button 214 and with a safety switch 216.
The support means 200 advantageously also include a front handle 220 projecting from the top surface 102 and situated substantially on the front end of the base 100. By having two handles 210, 220, it is possible to hold the gun with both hands.
The support means 200 also preferably include a forearm or elbow cradle 230 near the back end of the base 100. The forearm or elbow cradle 230 is in the form of a concave shel
