Description
- The present invention relates to an inertia rifle fitted with an improved trigger group.
- As is known, in the art inertia rifles and gas recovery rifles exist.
- In rifles functioning by means of inertia the recoil generated following firing is used directly to move the slide or obturator backwards; such backward stroke permits makes it possible both to rearm the hammer of the rifle and to place a new cartridge in the cartridge chamber according to a semi-automatic or automatic type functioning depending on the type of weapon.
- Such rifles functioning by means of inertia are quite simple as regards construction but do not always ensure precise, jam-free functioning. In fact, the use of cartridges having for example of relatively small calibres and therefore masses may cause the weapon to jam: in other words the inertial mass of the cartridge may not be sufficient to activate the inertial arming mechanism of the hammer and loading of a new cartridge connected with the backward stroke of the slide. Such rifles are therefore often constrained to use cartridges of a relatively high calibre.
- Alternatively it is known of to use gas recovery rifles in which part of the gas produced by firing is directly used to drive mechanisms, comprising levers and pistons, which cause the backward stroke of the slide so as to arm the hammer and load a new cartridge in the cartridge chamber. Such mechanisms can also function with smaller calibres having smaller firing forces: in fact the thrust exerted by the gas is amplified by the mechanisms connected to the recovery of gas and acting on the slide.
- Such gas recovery rifles are however more complicated to produce in that they require gas recovery mechanisms. An increase in the weight of the weapon results
- Consequently, the need is felt in the art for a rifle which is as simple and lightweight as possible and, at the same time, which does not jam even when using small calibre cartridges.
- The purpose of the present invention is to make a rifle which resolves the drawbacks mentioned with reference to the prior art.
- Such drawbacks are resolved by a rifle according to claim 1.
- Other embodiments of the rifle according to the invention are described in the subsequent claims.
- Further characteristics and advantages of the present invention will be clearer from the description given below of a preferred embodiment, made by way of a non-limiting example, wherein:
-
figure 1 shows a perspective view of a rifle according to one embodiment of the present invention; -
figures 1a and 1b show enlarged details offigure 1 ; -
figure 2 shows a perspective view of the rifle infigure 1 , from the side of the arrow II infigure 1 ; -
figure 3 shows a perspective view of the rifle infigure 1 , in a condition of movement of the trigger group; -
figures 3a and 3b show enlarged details offigure 3 ; -
figure 4 shows a perspective view of the rifle infigure 1 , from the side of the arrow IV infigure 3 ; -
figures 4a and 4b show enlarged details offigure 4 ; -
figures 5-7 show perspective views of the rifle infigure 1 , in subsequent phases of firing a cartridge; -
figures 6a and 6b show enlarged details offigure 6 . - With reference to the aforesaid drawings,
reference numeral 4 globally denotes a rifle comprising aslide group 8 and atrigger group 12. - The
slide group 8 comprises aslide 16 moving axially in a longitudinal direction X-X, parallel to a firing direction of therifle 4. - The
slide 16 has a backward stroke in relation to a closed position, in which theslide 16 closes and delimits rearwards acartridge chamber 20 able to house afirst cartridge 24 for firing. Theslide 16 also has a forward stroke wherein it returns to the closed position of thecartridge chamber 20. Theslide 16 is subject to the action of a spring which pushes it towards the closed position; such spring opposes the recoil effect impressed on theslide 16 by thefirst cartridge 24, as described further below. - The
slide 16 directly faces abase 28 of thefirst cartridge 24 so as to be subject to the direct recoil effect of the cartridge following firing of the same, to perform the backward stroke. In other words, the rifle is of the inertial type wherein the inertia of the bullet fired is used directly on the slide to impose the backward movement and subsequent loading of the weapon, as described further below. - The
slide 16 comprises afront portion 29 which interfaces directly with the cartridge to be fired and in particular which comes into contact with thebase 28 of thefirst cartridge 24. Saidfront portion 29 thus forms a wall or end of thecartridge chamber 20. Theslide 16 comprises, in addition, arear portion 30, opposite thefront portion 29 and suitable to interact with the trigger mechanism and in particular with the hammer of the rifle, as further described below. Theslide 16 comprises a firing pin (not shown) inside it, for example of the known type which, subjected to the action of the hammer, strikes thebase 28 of thefirst cartridge 24 generating the explosion of the blast of the latter. - The
rifle 4 further comprises thetrigger group 12 comprising atrigger 32 and means of activating the firing mechanism of therifle 4, listed below. - The
rifle 4 further comprises a cartridge magazine (not shown) containing at least onesecond cartridge 36 to load in thecartridge chamber 20 after expelling thefirst cartridge 24. - The cartridge magazine comprises a
push spring 40 which pre-loads thesecond cartridge 36 longitudinally, saidsecond cartridge 36 being housed inside the magazine substantially parallel to thefirst cartridge 24. - The
trigger group 12 comprises astop lever 48 and anelevator 52 suitable to interface with saidsecond cartridge 36 so as to block thesecond cartridge 36 at the insert of the magazine while thefirst cartridge 24 occupies thecartridge chamber 20 and so as to push thesecond cartridge 36 into thecartridge chamber 20 after the expulsion of thefirst cartridge 24. - The
stop lever 48 is joined to theelevator 52 so as to receive and block thesecond cartridge 36 on an insert of said cartridge magazine, and thesecond cartridge 36 is elastically pushed against alocking end 56 of thestop lever 48 in a direction substantially parallel to said longitudinal direction X-X. Such thrust is exerted by means of thepush spring 40 positioned inside the magazine (figures 1-2 ). - For example, the
locking end 56 of thestop lever 48 comprises aclaw 58 suitable to block on a perimetral rim of thebase 28 of the first cartridge 24 (figure 1b ). - The
stop lever 48 comprises thelocking end 56 which abuts directly against the base of thesecond cartridge 36 and aninterface end 60, opposite thelocking end 56, at which it interfaces with theelevator 52. - The
stop lever 48 is fixed to the body of the rifle by means of apin 62, positioned between saidstop 56 andinterface 60 ends. Thestop lever 48 is moreover influenced byelastic means 64 in rotation in relation to thepin 62. Theelastic means 64 are positioned on the opposite side to thelocking end 56, in relation to thepin 62; this way the elastic means 64 tend to rotate thestop lever 48 so as to release thelocking end 56 from thebase 28 of thesecond cartridge 36 to permit loading of thesecond cartridge 36 on theelevator 52. - The elastic action on the
stop lever 48 is contrasted by theelevator 52, on oneside 68 of the latter. In other words, theinterface end 60 of thestop lever 48, stops against acorresponding side 68 of theelevator 52, in a transversal blocking direction Y-Y (figure 1a ). Thestop lever 48 is elastically pre-sprung against theside 68 of theelevator 52, in said transversal direction Y-Y, by means of theelastic means 64. Transversal direction is taken to mean a direction perpendicular to the longitudinal direction X-X. - The
elevator 52 is elastically pressed away from thestop lever 48 by apush spring 72 and is blocked in position against thestop lever 48 by a catch 76 (figure 2b ). - The
elevator 52 is hinged to the body by atransversal pin 80 so as to be swivel mounted on a rotation axis parallel to said transversal direction Y-Y. - The
push spring 72 pushes theelevator 52 to rotate around thetransversal pin 80 away from the body, that is downwards. - The
elevator 52 is hinged in relation to thetransversal pin 80 so that following rotation of theelevator 52, the side of theelevator 52 is released from theinterface end 60 of the stop lever 48 (figures 3a, 4a ). - Such movement of the
elevator 52 is prevented by thecatch 76 situated, according to one embodiment, on the side opposite theassociable stop lever 48. - The
elevator 52 comprises aloading end 84 directly facing thesecond cartridge 36 and shaped so as to facilitate loading of the cartridge; for example saidloading end 84 comprises a downwardly inclined ramp so as to facilitate loading of thesecond cartridge 36. - According to one embodiment the
elevator 52 is joined in rotation with atooth 88 suitable to interface with the slide during its backward and forward stroke. - In particular, the
elevator 52 is joined in rotation to thetooth 88 which interferes with therear portion 30 of theslide 16 so that, in the backward stroke of theslide 16, thetooth 88 is pushed and the elevator is rotated, in a transversal direction towards thecartridge chamber 20, so as to insert thesecond cartridge 36 next to the cartridge chamber 20 (figure 6 ). - In particular, the tooth, in turn comprises a protuberance 92 able to engage in a
corresponding recess 94 made on theunderside 96 of the slide 16 (figure 6b ). So that during the forward stroke the protuberance 92 of thetooth 88 engages in therecess 94 and drags thetooth 88 with it causing theelevator 52 to rotate towards thecartridge chamber 20. This way thebase 28 of thesecond cartridge 32 is moved to the forward stroke of theslide 16 so as to interfere at least partially with thefront portion 29 of it. Such interference enables theslide 16 to push thesecond cartridge 36 fully inside thecartridge chamber 20. - The
trigger group 12 comprises thetrigger 32 operatively connected to ahammer 100 which acts by striking the firing pin, in the known manner. The movement of thetrigger 32 releases thehammer 100, previously cocked, so as to permit its lowering onto the firing pin. - Advantageously, the
trigger 32 is operatively connected to theelevator 52 so that, during the stroke of thetrigger 32 to perform firing, thetrigger 32 releases thecatch 76 of theelevator 52 and consequently thestop lever 48, so as to allow loading of thesecond cartridge 36 on theelevator 52 as described above. - According to one embodiment the
catch 76 of theelevator 52 is positioned on the opposite side to theassociable stop lever 48 and is operatively connected to the movement of thehammer 100 of therifle 4, so as to be released following lowering of thehammer 100. - The
hammer 100 is for example pushed by aspring 104 which lowers it against therear portion 30 of theslide 16; thehammer 100 is mechanically connected to afirst lever 108 hinged to atransmission 112 in turn connected to thecatch 76. As a result the movement of thefirst lever 108 permits the rotation of thecatch 76 which releases theelevator 52 as well as thestop lever 48 allowing loading of thesecond cartridge 36 on the elevator, as already described. - As may be appreciated from the description, the rifle according to the present invention makes it possible to overcome the drawbacks presented in the rifles of the prior art.
- In particular, the rifle is relatively simple and economical to make.
- The trigger mechanism is particularly efficient and may be efficaciously activated by the slide even using relatively small calibre cartridges, therefore having reduced inertia.
- In other words, the integration of the trigger group and the slide group according to the resent invention makes the semi-automatic functioning of the rifle possible without incurring in jamming even when using small calibre cartridges.
- The rifle according to the present invention is reliable and substantially free of jamming.
- In addition, the rifle according to the present invention has a reduced mass in that it does not envisage complex gas recovery activating mechanisms.
- A person skilled in the art may make numerous modifications and variations to the rifles described above so as to satisfy contingent and specific requirements, all contained within the sphere of protection as defined by the appended claims.
