RU2324884C1 - Ring thrower - Google Patents

Abstract

FIELD: weapons.

SUBSTANCE: invention pertains to sporting and hunting weapons. The ring thrower consists of bow, stock, frame and butt. The stock is cylindrical. The inner diameter of the frame is larger than that of the stock. The outer diameter is less than the internal diameter of the annular bullets. On the front end of the stock there is a guard for the frame, the outer diameter of which is less than the external diameter of the frame. The invention provides for increased wear-resistance.

EFFECT: increased wear-resistance of the weapon.

Description

Technical field

The invention relates to sports and hunting weapons.

State of the art

Known ringmet (see patent RU No. 2150651) containing onions, a trihedral bed, twisted along the longitudinal axis. However, when accelerating an annular bullet along a trihedral bed, part of the onion energy is spent on overcoming the sliding friction force. In addition, an expensive bed wears out quickly. The crossbow bed is elongated due to the fact that when fired, the carriage travels to the zero position (when the bow is unbent) and travels some distance due to the accumulated kinetic energy, which is extinguished by the reverse tension of the bow.

Disclosure of invention

In order to increase the caliber of the annular bullet and eliminate the above disadvantages of the prototype, the crossbow bed is cylindrical. The inner diameter of the carriage exceeds the diameter of the bed, and the outer is smaller than the inner diameter of the annular bullet. At the front end of the bed in order to reduce its length, a carriage stop is installed, the outer diameter of which is less than the outer diameter of the carriage. In this case, two diametrically opposite pins can be installed on the outer side surface of the carriage. Also, two diametrically opposite helical grooves can be made on the side surface of the carriage. In addition, at the rear end of the bed, a permanent magnet can be installed to hold the annular bullet before firing.

The proposed technical solution is illustrated in the drawing, where:

1 - bow, 2 - bed, 3 - carriage, 4 - bowstring, 5 - ring bullet, 6 permanent magnet, 7 - butt and 8 - carriage travel stop.

The work of invention

The order of firing from the ring is as follows.

The bow 1 is cocked, while the carriage 3 is fixed on the trigger. An annular bullet 5 is mounted on the carriage 3. A permanent magnet 6 holds the annular bullet 5 until the moment of firing. When you press the trigger, the carriage 3, together with the ring bullet 5, accelerates along the bed 2 with the bowstring 4 connected with bow 1. At the moment when the acceleration of the acceleration of the carriage 3 with the ring bullet 5 decreases to zero, the ring bullet 5 slides off the carriage 3 and flies to the target, and the carriage 3 is stopped by the stroke limiter of the carriage 8. In this case, if the outer side surface of the carriage 3 is provided with pins, and screw grooves are made on the inner surface of the annular bullet 5, the annular bullet 5 is twisted in the axial direction (when leaving the carriages and). The same thing happens if the grooves are made on the carriage 3, and the annular bullet 5 is provided with pins.

The second option of twisting the annular bullet 5 is more technologically advanced than the first, however, the weight of the carriage 3 in this case is more than in the first.

If the point of application of the weight of the annular bullet 5 is in its front part, and the center of pressure is in the rear part, then the annular bullet 5 may not require the implementation of the 2nd or 3rd claim. In this case, an additional twist of the annular bullet 5 by the oncoming air flow during its flight is possible, for example, due to the implementation of the shank of the bullet in the form of a turbine.

To shoot at moving targets, instead of one or more annular bullets 5, an annular container with metal balls (shot) can be installed on the carriage 3.
