Hunting rifle recoilless buttstock
Stock for a recoilless hunting rifle, for medium and large caliber hunting guns, which eliminates the stress produced by the effect of the recoil on the shooter's shoulder, providing at the same time good targeting precision and reduced consumption of bullet cartridges or shot cartridges. The stock has a stock butt and a mechanical anti-recoil module, with fast assembling, and a gun stock resembling the classical gun stocks but without transferring the recoil force to the shooter's shoulder. The recoilless buttstock includes a mechanical anti-recoil module, presented as an assembly having a pair of coupling parts, an elastic mechanism, a fixed support with rollers, an upper guide with a spring, a lower guide with a spring and the case of the stock.
1. A hunting rifle recoilless buttstock comprising:
a stock body provided with a passing hole and a mounting screw;
an anti-recoil module comprising a pair of coupling parts, an elastic anti-recoil mechanism, a fixed support with rollers, an upper guide with a first spring and a lower guide with a second spring;
the elastic anti-recoil mechanism comprising:
a fixed joint plate, which is coupled to ends of a pair of pushing levers by way of a joint pivot having a lock;
the other end of the pair of pushing levers being coupled to each end of a pair of elongated levers by a joint spring carrying pivot having a lock;
the elongated levers being joined at their centers by a joint rivet, while the other ends of the elongated levers are coupled to screwed spring carrying pivots; and
a first absorption spring, a second absorption spring, annulling springs and a blocking-compensation spring;
wherein the elastic anti-recoil mechanism has an operation relationship to said fixed support with rollers and upper and lower return springs.
2. The hunting rifle recoilless buttstock of claim 1 , wherein the first absorption spring is arranged between the joint spring carrying pivots at each of their ends, the second absorption spring is arranged between the screwed spring carrying pivots at each of their ends, while the annulling springs with the respectively screwed spring carrying pivots, are arranged between the back ends of the elongated levers and the fixed support with rollers.
3. The hunting rifle recoilless buttstock of claim 1 , wherein the fixed support with rollers comprises a fixed central support, blocking rollers, which are mounted on corresponding roller carrier pivots, a blocking-compensation spring, which is mounted within a circular notch, the fixed central support being fitted on a bed plate with mounting screws.
4. The hunting rifle recoilless buttstock of claim 1 , wherein at its upper and lower parts, the fixed central support has screwed spring carrying pivots for the annulling springs, and the bed plate is provided with an adjustment screw.
5. The hunting rifle recoilless buttstock of claim 1 , wherein the entire anti-recoil module is enclosed in a stock case which is fitted with the mounting screws.
6. The hunting rifle recoilless buttstock of claim 1 , wherein the upper guide with a first spring comprises a screwed rod assembly, an ending ring, an upper return spring, a guiding bolt, a screwed guiding member and a bolt nut.
