Abstract

The invention relates to projectile weapon and can be used for hunting and for submarine, sport and entertaining shooting. The inventive pulley-provided projectile weapon comprises a gunstock (1), the lower part of which is provided with fixed thrusts (11, 12). An elastic strain mechanism is placed between said thrusts (11, 12). The front part of the gunstock is embodied in the form of fixed arms (2) which are arranged perpendicularly to a longitudinal axis. Said arms comprise three pairs of rotatable receiving pulleys (3) which are fastened, at an angle of 90° therebetween, to a corner fixed to the gunstock, guides (5) which are connected to the front vertical surface of the fixed arms and bow-string forming means which are fixed to the ends of the top part of the fixed arms (7). The invention makes it possible to produce a small-sized weapon, to exclude the side displacement of the bow-string and the jump of the weapon and to protect against the bow-string rupture.

Description

Title

Spring (vacuum) - block throwing weapon.

Technical field

Throwing weapons (throwing arrows). Designed for hunting, sport shooting, recreational shooting, can be used for spearfishing.

The prior art has no analogues.

SUMMARY OF THE INVENTION Creating a new type of throwing weapon.

Technical result

1. In the design of weapons, the following sources of mechanical energy are used:

A. Energy of a coil spring working in compression or

B. Energy of a coil spring operating in tension or

B. Discharged gas (vacuum) energy Hybrid combinations possible

2. The weapon can be used both for entertaining shooting and for hunting. The strength of the bowstring tension varies widely from 20 to 150 kg. To increase power, it is enough to replace the coil spring (tools and accessories are not required). Spring replacement time 1-2 min.

An increase in the power of a weapon using vacuum energy is carried out by pumping air from a vacuum cylinder. Pumping is performed by a special pump. The degree of vacuum in the vacuum cylinder is controlled by the vacuum gauge.

SUBSTITUTE SHEET (RULE 26) 3. The weapon fires in the air and in the water column.

4. The power of the orcish depends on the range of the fixed shoulders, the characteristics of the twisted spring (length, diameter, wire thickness, inter-turn distance, speed).

5. The weapon is compact. The range of fixed shoulders - 40 cm provides sufficient power and high speed boom flight. The bowstring speed is 1.7 times higher than the straightening (compression) speed of a twisted spring (if the shoulder span is 40cm). If the shoulder span is more than 40 cm, then the bowstring speed is 2 times higher than the straightening (compression) speed of the twisted spring. Conversely, the smaller the swing of the fixed shoulders, the lower the speed of the bowstring.

6. 100% lack of lateral displacement of the bowstring.

7. Lack of feedback.

8. The weapon is safe when a bowstring breaks.

9. The weapon is well balanced.

10. Short motionless shoulders allow you to hunt in dense vegetation.

11. To quickly discharge the vacuum weapon, in which the bow is in a tense state, it is necessary to open the quick-release valve. The pressure inside the vacuum cylinder is equal to atmospheric.

12. The weapon is equipped with a fuse that blocks mechanical energy sources.

Spring (vacuum) - block throwing weapon.

The weapon consists of: a weapon bed 1 (Fig. 1; 3), fixed shoulders 2 (Fig. 1; 2). On fixed shoulders are three pairs of blocks. A ball bearing is pressed in the center of each block. The first pair of blocks are receiving 3 (Fig. T). The receiving blocks are attached to the bottom of the fixed shoulders through the corner 4 (Fig. 2). The angle between the receiving units is 90 °. The second pair of blocks - guides 5 (Fig. 2). The guide blocks are attached through the stirrup 6 (Fig. 1; 4) to the front vertical plane of the shoulders. The third pair of blocks is string-forming 7 (Fig. 1; 2; 3). The bow-forming blocks are located on the edges of the shoulders parallel to the upper plane. A cable 8 passes through the blocks (Fig. 1; 2; 4). The cable passing between the string-forming blocks is a string 9 (Fig. 1; 2). On the gun bed is the retention mechanism of the bowstring 10 (Fig.l). Two stops 11; 12 are fixed on the lower part of the bed (Fig. 3). The emphasis 11 (Fig. 3), is part of the fixed shoulders. Between the stops 11 and 12, in the pipe 13 (Fig. 3; 4; 5), a spring or vacuum mechanism is located.

A. The device of the spring mechanism using the energy of a twisted spring, working on compression:

Through pipe 13 (Fig. 3; 4; 5). Inside the pipe are located: twisted compression spring 14 (Fig. 4; 5), piston 15 (Fig. 4; 5). Two cables 8 are attached to the piston (Fig. 4; 5), the cables pass through the spring parallel to each other. At the end of the pipe 13 adjacent to the abutment 12 is a pad of soft rubber - emergency shock absorber 16 (Fig. 4; 5). Fuse 17 (Fig. 5).

Through pipe 13. Spring 14, the rear end of the tension spring can be attached to the stop 12 or to the pin 18, two parallel cables are attached to the front edge of the spring 8. A fuse 17 can be installed in the spring mechanism. To install a fuse 17, it is necessary between the parallel cables 8 and the end of the spring 14 to install a light piston 15.

SUBSTITUTE SHEET (RULE 26) Work

A. Spring (vacuum) - block throwing weapons using the energy of a twisted spring working in compression (Fig. 5; 6)

When the bowstring tension is 9- → 9A (Fig. 1), two cables 8 pull the piston 15. The blocks rotate - they direct the cable. Fuse 17 blocks the piston. To fire the shot, turn off safety 17. At the moment of the shot, the mechanism for holding the bowstring 10 releases the bowstring 9A. The spring 14 is straightened by moving the piston 15. The piston pulls two cables 8, the blocks rotate, guide the cable. Bowstring 9 A - »9 (Fig. 1) is straightened and a shot occurs. Compressed air generated during the movement of the piston enters the decompression hole located at the stop 12. In the event of a bowstring break, the blow of the freely moving piston 15 is suppressed by the soft rubber gasket 16 (emergency shock absorber).

With a swing of fixed shoulders of 40 cm, a working stroke of a bowstring of 30 cm, the working stroke of the spring (piston) is 17 cm.

Work

B. Spring (vacuum) - block throwing weapons that use the energy of a twisted spring working in tension (Fig. 7; 8).

When the bowstring 9- → 9A is tensioned (Fig. 1), two cables 8 pull the tension spring 14. The blocks rotate to guide the cable. The spring 14 is stretched.

If the fuse 17 is installed in the design, then two cables 8 pull a light piston 15. In this case, the fuse 17 blocks the compression of the spring 14 through the piston 15. To fire the shot, it is necessary to turn off the fuse 17. At the moment of shooting, the bowstring 9A → 9 (Fig. 1) is released from the holding mechanism 10. The spring 14 is compressed, pulls two cables 8, the blocks rotate, guide the cable. The bowstring straightens, a shot occurs.

With a swing of fixed shoulders of 40 cm, a working stroke of a bowstring of 30 cm, the working stroke of the spring is 17 cm.

Work

B. Spring (vacuum) - block throwing weapons that use the energy of a discharged gas (vacuum) (Fig 9; 10).

When the string 9- → 9A is tensioned (Fig. 1), two cables 8 pull the piston 15. The blocks rotate - they direct the cable. When the piston moves, the volume of the sealed chamber 18 increases. With an increase in the volume of the chamber 18, an increase in the degree

SUBSTITUTE SHEET (RULE 26) gas discharge. The movement of the piston 15 blocks the fuse 17. For firing, you must turn off the fuse 17. At the moment of shooting the bowstring 9A- → 9 (Fig. 1) is released from the holding mechanism 10. The piston 15 moves to the stop 12, pulls two cables S. The blocks rotate, directing cable. The bowstring straightens, a shot occurs. When a bowstring breaks, the shock absorber takes over the piston stroke 16. The vacuum gauge 20 shows the degree of vacuum in the vacuum chamber 18. The pump for additional air pumping 19 allows you to change the power of the weapon over a wide range. If the weapon is on a combat platoon, and you need to make it safe (without a shot). Open the quick release valve 21. The pressure in the chamber 18 is equal to atmospheric.
