Abstract: A bow includes a string; a frame for resting a projectile, with a first wing and a second wing and a middle portion in between; a first limb attached on an end of the first wing at a distance, the first limb having a first free end and a second free end with first and second placing means for positioning the string; a second limb attached on an end of the second wing, the second limb having a first free end and a second free end with first and second placing means for positioning the string; a first deflecting means for pulling the string from the first placing means and the second placing means of the first wing, and a second deflecting means on the first wing between the middle portion and the first limb; same for the second wing. The string crosses a path of the projectile only once.

Abstract: This invention belongs to the group of projectile throwing instruments working without an explosive or a combustible propelling charge in particular to the group of projectile throwing instruments using strained hard body energy and can be used for the design and construction of a missile throwing weapon using a string—namely a bow and crossbow.

Abstract: A unit for fastening a bowstring of a throwing device the containing a first pulley mounted with a possibility of rotation about the axis of rotation of the first pulley and having the first and the second peripheral surfaces, the second pulley mounted with a possibility of rotation about the axis of rotation of the second pulley, spaced apart from the axis of rotation of the first pulley and having the first and the second peripheral surfaces, a bowstring for throwing a projectile having one end fixed to the first pulley, and other end fixed to the second pulley so the bowstring for throwing a projectile is, at least, partly wrapping the first peripheral surfaces of the first and the second pulleys, the first tension bowstring having one end fixed to the axis of rotation of the first pulley, and other end fixed to the second pulley so the first tension bowstring is, at least, partly wrapping the second peripheral surface of the second pulley, the second tension bowstring having one end fixed to the axis of r

Abstract: This invention relates to sporting and hunting throwing weaponry, more specifically, crossbow. The crossbow comprises a limbs riser, limbs oriented towards the shot direction, cams installed on the ends of said limbs, bowstring and cables passing through said cams and a barrel on which said limbs riser, a trigger mechanism and a foregrip are installed.

Abstract: The invention relates sports and hunting throwing weapon. Reverse crossbow contains limbs riser 1 in combination with limbs 2, cams 9, bowstrings and cables 11, 12, 13, a barrel where said limbs riser is placed, a trigger mechanism 4 and a foregrip. The limbs riser 1 of limbs 2 is located on the edge of the barrel behind the trigger mechanism 4 and is centered about the barrel using a cone. The initial angle of installation of limbs 2 on their riser and the distance between the points of their fastening is chosen in such a manner that when rising the crossbow the axis of rotation of each cam 9 crosses the line parallel to the central axis of the crossbow. The cam 9 is placed with a possibility of rotation, where during such a rotation the said mechanical center does not cross the straight line parallel to the straight line connecting the mechanical center of said cam and the exit point of the said bowstring.
