Definitions
- the technical field of the invention is that of non-selective single-shot rifles, the stroke of which relaxation is limited by safety.
- the present invention relates more particularly to an adjustable safety allowing limit the trigger stroke after triggering the first time to provoke faster hooking the second shot.
- the user can bring out at his convenience the movable part of the channel so as to increase the length apparent from the elongated part of the security.
- the internal channel consists of an upper channel threaded in communication with a lower channel located in the elongated part of the safety, said channel upper containing a screw.
- the channel upper is inclined to the lower channel and the screw has a pointed end.
- the screw is a needle screw.
- the unscrewing of the screw can cause a displacement of said part in direction reverse allowing to decrease the length of the protrusion.
- a ball is inserted between the upper channel screw and one end of the cylindrical part housed in the lower canal.
- the ball is in steel.
- the pointed end of the screw is pyramidal in shape four sides.
- the screw is a six screw HC hollow sides.
- Screwing the screw into the upper channel generates pressure on the ball. This pressure is returned on the cylindrical part which will move in the lower channel.
- the precision of the adjustment corresponds to the displacement of the cylindrical part induced by a quarter-turn rotation of the screw. This precision is possible thanks to clicks caused by the ball when the user turns the screw and that occurs during successive contacts of the ball with the faces from the pointed end of the screw.
- all interfaces implemented in safety are nitrided to slow the wear of all parts in contact with each other.
- the screw is a six screw HC hollow sides.
- the end of the screw serving as a stop is flat.
- the adjustable safety according to the invention presents the advantage of being machined from the safety system existing without any retouching of the rifle. Moreover, the user can adjust the stop without dismantling the rifle using a wrench or a simple screwdriver, thus authorizing the adjustment operation on the launch pad. In addition, the association of a pointed screw with four faces and a ball in the mechanism of the adjustable safety allows fine and precise adjustment of the length of the stop. Ultimately, adjustable safety according to the invention provides the user with comfort allowing it to improve rifle performance.
- Figure 1 is a view in section of adjustable safety.
- Figure 2 is a diagram for repositioning adjustable safety compared to the trigger tail.
- the adjustable safety consists of a single piece 1 which distinguishes an upper part 2 emerging from the rifle and an elongated lower part 3.
- the upper part 2 is hollowed out by a straight cylindrical threaded channel 4 of which one end located in depth of safety 1 is closed and the other end is open.
- Said channel 4 contains an adjustment screw 5 which is composed of a cylindrical body having a pointed front end 6 pyramid-shaped with four faces and one end flat rear 7 whose central part is hollowed out thus making appear a hexagonal recess.
- the adjusting screw 5 is introduced into channel 4 by its pointed front end 6, then screwed in at its rear end 7 using a hexagon wrench.
- the elongated lower part 3 is hollowed out by a cylindrical channel with an internal shoulder making it possible to distinguish an upstream channel 8 and a channel downstream 9 of larger diameter, said upstream channel 8 being in communication with the cylindrical channel 4 of the upper part 2 near its end closed.
- the cylindrical channel of the lower part elongated 3 contains a one-piece cylindrical part having an upstream part 10 occupying the upstream channel 8.
- Said upstream part 10 is extended by a base cylindrical enlarged 11 intended to come into abutment against the internal shoulder, said upstream part 10 being terminated by a downstream part 12 of the same diameter.
- the one-piece cylindrical piece is held in the channel from the elongated lower part 3 through a spring 13 surrounding the downstream part 12 and compressed between the enlarged base 11 and a reamed ring 14, threaded on its outer surface.
- Said ring 14 is screwed inside the downstream channel 9 and is crossed by the downstream part 12 of the one-piece cylindrical part.
- a steel ball 15 whose diameter is slightly lower than that of the upstream channel 8 is interposed between the adjusting screw 5 and the workpiece cylindrical monobloc housed in the channel of the part lower.
- the precision of the stop adjustment corresponds to displacement of the moving part when the screw 5 has been quarter turn tour.
- the setting of the setting is made possible by the clicks caused by the ball 15 when the user turns screw 5 and which produced during successive contacts of the ball 15 with the faces of the pointed end 6 of the screw 5.
