Definitions
- the present invention relates to improvements made to air rifles of the tilting barrel type, serving as a lever for a mechanism intended to compress a spring located in the compression chamber, said barrel comprising, on its rear end, an enlarged casing which comprises essentially a transverse stud and a pawl intended respectively for its articulation and for its locking on a fork which ends in a cylindrical part made integral with the compression chamber mounted on the barrel of the stick, this cylindrical part comprising an axial communication conduit with said compression chamber, which aligns coaxially with the axis of the barrel, in the cocking position.
- the object of the invention relates mainly to the particular embodiment of the fork-shaped part, articulated on the barrel, and its attachment to the end of the compression chamber, as well as to the realization of the rear part of the 'envelope of said barrel, essentially determining a significant saving in the cost of producing each piece, without reducing the functional and precision characteristics of the parts concerned by the improvements.
- the requirements that said fork must have are, in addition to ensuring the hermetic connection of the end of the compression chamber, those of allowing a positioning of the barrel, in closed position, with coaxial alignment of the axis of the body. of said barrel with the axial duct for the outlet of the compressed air from the compression chamber.
- the object of the invention is to solve the aforementioned drawbacks, by implementing an embodiment of the parts used providing a significant saving in the cost of production without losing the performance of the rifle.
- it is the ease and economy of production which is sought by combining the functions of connection, articulation and centering on two molded sub-assemblies and using a barrel and a compression chamber of a classic type.
- the invention proposes an embodiment of the fork-shaped part which terminates the compressed air chamber and which comprises the axial duct which aligns coaxially with the axis of the barrel, in the cocking position, innovative, making it possible to obtain said piece in the form of a one-piece body produced by means of an injection molding operation of an appropriate material, advantageously a plastic material of high strength and mechanical strength, capable of withstanding shocks and frictional forces. and shear, with a cylindrical rear part capable of being inserted with adjustment in the front inlet of the compression chamber, comprising hermetic means interposed between the corresponding profile and fixed by simple transverse rods, thus significantly simplifying the manufacturing process allowing savings on each assembly produced.
- the enveloping part of the rear portion of the barrel enlarged and provided with holes for articulation, holes for fixing the spring loading lever, a cavity for mounting the locking element of two parts of the rifle, in the closed position, and of the raising support, intended to be connected to the fork in an articulated manner, is also obtained by means of a molding operation by injection of a material, in particular plastic such as that mentioned above, which produces both a complete envelope of said barrel, with an orifice at its front end for the exit of the projectiles with a rear portion of said barrel projecting from said envelope .
- the rifle shown in the figures comprises a tilting barrel 1 serving as a lever for a mechanism of articulated levers 13 intended to compress the spring 2 associated with the piston 27 of the compression chamber 3, said barrel comprising at its rear end, an enlarged casing 4 which essentially comprises a transverse stud 5 and a pawl 6 intended respectively for its articulation and for its locking on a fork 7 which ends in a cylindrical part 8 made integral with the compression chamber mounted on the barrel of the stick: said fork and its cylindrical extension being constituted by a one-piece body which is produced by means of an injection molding operation of a suitable material, in particular plastic material of high strength and mechanical strength, said one-piece body being attached to the rear part of the compression chamber, by adjusted insertion of its cylindrical part, with a pre-assembly lable of coaxial hermetic means 9 in particular of the O-ring type, the two parts being firmly fixed by means of transverse studs 10 which pass through the cylindrical part of the fork extension and the wall of the compression chamber, ensuring the fixing
- the casing 4 of the rear part of the barrel, enlarged, provided with orifices intended for its articulation 5 with the fork and for fixing 12 of the compression lever 13 of the spring of the compression chamber, of a housing 14 for the mounting of a locking element, in particular a pawl 6, of the rifle in the closed position and of a raising support 15, is also carried out by means of an injection molding operation which makes it possible to obtain the complete envelope of said barrel with an orifice on its front end for the exit of the projectile and a rear section 16 of said barrel, projecting from the rear part of said casing, designed to adapt to the existing configuration 17 in the bottom of the fork, intended for its adequate centering.
- the connecting part of the casing 4 of the rear section of the barrel to the compression chamber 3 is formed of a one-piece body with an advantageously cylindrical part 8, massive, of adequate diametral dimension to allow its connection with said chamber by a fitting adjusted at the front end thereof, which is extended by a fork shape 7 which comprises two parallel branches 18, substantially symmetrical, of planar internal faces connected by an intermediate face 19, also planar and which is limited by a wall 17, located below an orifice opening from an axial duct 20 to the cylindrical section which communicates with the compression chamber, wall which has, on the side closest to said orifice, a rebate 17 of semi-shaped cylindrical, centered with respect to said orifice, to serve as a support for the rear section of the barrel 16 in excess and for coaxial centering of the axis 21 of the body of said barrel with the conduit t axial outlet 20 of the compressed air from the compression chamber, and on the opposite side of said wall, a sloping plane 22 which is located opposite the locking element in the closed position of the rifle, said wall being
- the axial communication conduit 20, which passes through the cylindrical part of the monobloc body of fork configuration, opens onto a cylindrical cavity 24 located at the base of said fork, intended to contain a seal 25, also cylindrical, comprising a central passage in the extension of the axial intercommunication duct with the compression chamber, slightly projecting from the bottom plane of the fork.
- the one-piece fork configuration has, on the outer surface of the parallel legs of the fork, longitudinal ribs of reinforcement 26 which extend over an area which surrounds the orifices through which the pin 5 serving for the articulation of the two parts of the rifle passes.
