Abstract

This invention belongs to projectile throwing instruments that use the energy of the strained hard body and can be used for the design and construction of a missile throwing weapon—namely for a bow and crossbow.

Claims

1. A cam with separated peripheral surfaces for the projectile throwing instrument is installed on the free end of the thrower'"'"'s limb, which is able to spin and has peripheral surfaces that give way to the string and cable strings. With this, the string'"'"'s peripheral surface stands from the cable strings'"'"' peripheral surfaces at a distance far enough to allow for the string and at least one cable string, in which the distance between the string'"'"'s peripheral surface and the nearest peripheral surface is enough for the cable string not to hinder the path of the thrown projectile. Moreover, the cable strings are completely intercrossed.

2. The cam of claim 1 wherein the cable strings are not intercrossed.

3. The cam of claim 1 wherein the symmetry axis coincides with the spinning axis.

4. The cam of claim 1 wherein the symmetry axis stands off from the spinning axis.

5. The cam of claim 1 wherein the cam is of a round shape.

6. The cam of claim 1 wherein the cam is of a non-round shape.
