RU2229082C1 - Balanced arbalest with kickback multibow - Google Patents

Abstract

FIELD: sporting weapon. SUBSTANCE: the balanced arbalest has a kickback multibow, whose unlimited quantity of block arms is installed on a joist perpendicular to the bed, and the arms are directed towards the bed, butt, trigger mechanism, bow-string tensioning mechanism. The block arms are located on a tapered surface formed by rotation of the block arm about the joist, the axes of the block arms. Besides, the two blocks that are nearest to the arrow may be installed on brackets with the axes of their rotation, parallel with the direction of the bow-string section connecting any of these blocks to the previous one. EFFECT: enhanced power of a shot from the arbalests and its compactness. 2 cl, 5 dwg

Description

The invention relates to sports and hunting weapons.

Known crossbow (see patent RU No. 2015488 C1, class F 41 5/00, 06/30/1994) containing two block bows, a box, a stock and a trigger.

However, the crossbow has large dimensions, and when fired, the center of gravity of the front bow is shifted, which reduces the accuracy of shooting.

The closest analogue is a ring-thrower (crossbow), described in patent RU 2150651 C1, class. F 41 B 5/12, 10.06.2000.

In this balanced crossbow containing a reverse multi-bow, whose block shoulders are mounted on a crossbeam perpendicular to the bed and directed towards the bed, butt, trigger, bowstring tension mechanism, the idea of a balanced reverse bow is laid down, allowing to keep its center of gravity invariant at the time of the shot, and by turning the bow shoulders through 180 °, it became possible to reduce the angle between the bowstring and the direction of acceleration of the ring to almost zero.

The objective of the invention is to increase the power and compactness of the crossbow.

The technical result is achieved due to the fact that in a balanced crossbow containing a reverse multi-bow, whose block shoulders are mounted on a crossbeam perpendicular to the bed and directed towards the bed, butt, trigger, bowstring tension mechanism, according to the invention, an unlimited number of block shoulders are installed on said crossbar located on a conical surface formed by the rotation of the block shoulder around the crossbar, while the axes of the blocks are parallel to the longitudinal axes of the block shoulders.

In addition, the two blocks closest to the boom are mounted on brackets with their rotation axes parallel to the direction of the section of the bowstring connecting any of these blocks with the previous one.

The invention is illustrated by drawings, where figure 1 shows a General view of a balanced crossbow; figure 2 is a possible sequence of connecting blocks of a bowstring; on figa - one of the possible layout of the crossbow, a view in the working position, on figb - the same in the passage position; figure 4 is a side view of the crossbow, where the dotted lines show the crossbow in the stowed position, and solid in the working position.

The crossbow has a box 1, butt 2, arrow 3, winch 4, crossbar 5, shoulders 6, bearing blocks 7, bowstring 8. The crossbar 5 is installed perpendicular to the bed 1. At the ends of the crossbar 5 an unlimited number of shoulders 6 with blocks 7 can be fixed the block arms 6 lie on a conical surface formed by the rotation of the block arm 6 around the crossbar 5. The axis of rotation of the blocks 7 are parallel to the longitudinal axes of the block arms 6. The two blocks 7 closest to the boom 3 can be mounted on brackets whose rotation axes are parallel to the direction A string of string 8 connecting any of these blocks to the previous one.

The crossbow works as follows. Arrow 3 is installed on the box 1, after which, using the winch 4, the string 8 is tensioned, while the blocks 7 are pulled to the crossbar 5. At the time of the shot, the block shoulders 6 are unbent, doing the work of accelerating the arrow 3. Block shoulders 6 with blocks 7 are returned to starting position. Moreover, if the two closest (by bowstring) to the boom 3 of block 7 are mounted on the brackets, then they are rotated approximately 90 ° using the axes located in their brackets.

The number of shoulders in the crossbow is not limited, while the general center of gravity of the multiloke practically does not move during cocking, which increases accuracy. Moreover, the sequence of connection of blocks 7 by bowstring 8 is not limited, i.e. can be any (see, for example, figure 2).

The crossbar 5 can be deployed during transportation of the crossbow (see, for example, figb).

To increase the versatility of the crossbow, the bed can be interchangeable. The crossbow can shoot both arrows and twisted rings.

The crossbow has a high power shot and sufficient compactness.
