FIREARM WITHOUT RECOIL
Document Type and Number:
WIPO Patent Application WO/2000/029803
Kind Code:
A1
Abstract:
A recoil free rifle consists of a fixed (F) and a mobile (G) assembly. The fixed assembly (F) comprises a barrel guide support (H) and a recoil mechanism support (I), both of them connected to each other by a handle bar. On firing, the recoil experienced by the mobile assembly (G) comprising the barrel (2), the rifle body (3), and the support of the rifle stock (4) is absorbed by an antirecoil mechanism (J) connecting both of the assemblies.

Description:
FIREARM WITHOUT RECOIL The patent refers to a rifle without recoil, from the portable arms category used as guns or simple, authomatic or semiauthomatic rifles (lestinated for precise shots upon static or mobile target from"stand up"or"lay down"position.

A rifle is made up by a barrel, a shell store, a handly or authomaticaly load and n stock in which you can fix the barrel. At the execution of shooting you have to put the barrel on the direction of the target, fix well the stock into the frontal! ; Ide of shoter's shoulder, take the target line and pull the trigger with your finger detaching the timing pin. This rifle presents the following drawback: the force of the recoil should be tak<n over by the shoter's shoulder and in the same time this influences in the negative way upon the precision of shooting by drawing the barrel out of the terget line.

It is known that a rifle stabilization devrce fLxed 3t its hinder side, made up bv a catching handle and a frame which extends to backward: of the mentioned handle. In the empty space from inside the frame the shoter introduces his arm rad fixes it there, such as the forces aroused by the recoil to be taken over by the shoulder's superior, hinder and inferior side together with the side which contain the handle and aply a supplement ry force, which contnbutes to the stabilization of arm (patent request P. C. T. W 081/2925 SUA 1980).

The technical problem which is solved by this patent, consists in the annihilation, almost entirely, of the recoil's energy action such as the hand remains stable on the target direction.

The rifle without recoil, in accordance lsith the patent, solves the uppvr technical problem, by being endowed with a static ensemble contaicing a previos and a hinder support mited by a metalic bundle and a mobile ensemble containing a catching support of the stock and a absorbtion mechanism of the recoil's energy. The barrel guic, e support, contains a body, a barrel guide and a bringing back resort, the support body presenting some holes, and the barrel guide presents some screwed on orifices which solidaries the body wii : h the barrel guide throw some screws. The hinder support contains a tubular body, a consolidation addition, a carcasse and a catching ring for the ansamblation and consolidation of the mentioned components throw some screws. The tubular body presents a support for setting the metalich bundle, a guide at the superior side, a guide at the inferior side, some guide windows on the lateral sides, a mndow and a screwed orifice, applied into a sole which presents at the hinder side a camp. Th : catching ring presents a ear with holes for screws and another ear for the fixing screws. The support is bound with the rifle body throw two screws and with the levers of recoil's mechanisw throw two axles containing guide roles, a circular guide lever of the articulate parallelogram, is presented with a window in which an axle skates, some resorts provide for reversible elastic bundles, between quadrilaterals, between the lever and the rifle's fixed ensemble.

The rifle without recoil presents the follomng avantages: -it eliminates, almost entirely, the recoil's energy of the existing guns; -it ensures great posibilities that the target line to remain the same in the moment of fire by fire percussion and authomaticaly fire; -the rifle's fire without recoil mechanism can be used at all kinds of guns.

In the following context we present you urn achievment example of the patent and the figures from 1 to 13 which represent: -fig. 1, lateral view with section throw n : ile's stock; ; -fig. 2, lateral view with a break throw the barrel's guide support; -fig. 3, transversal section after a plan} i-S throu the support from fia. 3 ; -fig. 4, view with section in longitudinal plan throw the antirecoil mechanism's hinder support; -fig. 5, longitudinal section throw the catching support of the rifle's stock and the bound with the rifle's body; -fig. 6, transversal section after a plan B-B throw the support represented by fig. 4; -fig. 7, horizontal section after a plan C-C throw the support from fig. 4 -fig. 8, bound ring's view in transversal plan; -fig. 9, longitudinal section throw the catching support of the rifle's stock : -tig. lU, section after a plan D-D throw the catching support from fig. 9; -fig. 1l, lateral view of antirecoil machamsm; -fig. hoiizontal plan of the anncecoil mechanism; -fig. 13, section after a plan E-E throw atKirecoil mechanism from fig. 11.

The rifle without recoil, in accordance with the patent, is made up by a first fixed F ensemble with the role of catching, mounting and manipulation and a second G ensemble with relativ mobility as the first, having the role to get fire, guide and expel the bulit towards the target, absorbtion of the recoil's energy and rille's stability ensurance on the target line.

The fixed G ensemble has in composition an H barrel's guide support, set on the previous side of the rifle, a support of the absorbtion mechanism of the I recoil's energy set on the hinder side, and a bandle bar 1 which solidarises the ensembles H and I.

The mobil G ensemble has a tube 2, a rifle body 3, a catching support of the rifle's stock 4 and a antirecoil mechanism J.

The guide support of the guide tube H (fig. 2) is made up by a body 5, a barrel guide 6, a btingback resort 7 and a ring for the position of the resort 8. The body 5 (fig. 3) is tubular for catching the profile of the rifle and presents on the lateral sides some holes a, and the barrel guide 6 has some screwed lateral orifices b which ensure the solidarization of the body 5, with the barrel guide 6 throw some screws 9.

The recoil's mechanism support I (fig. 1) represents a complex ensemble made up by a tubular body K (fig. 4), which joins with a addition of consolidation 10, at the inferior side (fig. 5), a carcasse of the stock 11 at the hinder side, having the role of closing and protecting, and a catching ring 12 which realizes the ensemble's consolidation. These blended are achieved with some screws 13,14,15,16 (fig. ).

The K tubular body (fig. 4) has at the superior side a support in U fettle 1/ (fig. 6) in which is fixed the bundle bar 1 (fig. 1), and at inferior s. ide has some guide elements such as: a parallelipipedic guide at the superior side and at the inferior side 18,19 and some guide windows c, d, parallels and by different lenghts, on the lateral sides of the body. Into a sole o from the K body's base is practised a f window, and at hinder extremity of this thereis a camp 20 of fixmg the recoil mechanism (fig. 4,7).

In the sole"o"there is also a screwed oriGce"g", throw which the Gxing screw 15 of the stock's carcasse passes by K support.

The catching ring 12 (fig. 8), is oval, as the stock fettle and it has an ear H. with two holes for the screws 16 at the superior side. and with another ear I, also with two holes for the screws 13,14.

The rifle's stock support 4 (fig. 5), penetrates guidely in the tubular body K and it is bound with the rifle's body throw two screws 21,22 and with the levers of recoil's mechanism throw two transversal axles 23,24 (fig. 9,10) which ar< gifted with two guide i-ous 25, which skate in the lateral windows"c, d" body, being ensure with some fuses 26.

The antircoil mechanism J (fig. 1,5) is ar ensemble made up by three umiculated parallelograms, set between the fix side of the"F"hfle (Hg. l) and the rifle's side with relative mobility 6 (fig. l). The antirecoil mechanism (fig. 11,12,13) absorbs the rifle's recoil energy in the percussion moment such as: between the rifle's fix side F (fig. 1) and the rifle's mobile part G is made up the functional mounting of the antin coil mechanism, throw the 45 axle (Gg. 11) of the camp 20 (fig. 4) from the composition of the tubular support K of the rifle's catching support stock 4 (fig. 5)
