Each of said limbs having a loose end. The crossbow further includes a first cam having a first rotation axle and a second cam having a second rotation axle. The cams rotatably arranged on a first holder and on a second holder, respectively. The holders fixed on said frame on opposite sides from the movement trajectory. In addition, the crossbow is provided with a bowstring connecting the first cam and the second cam, a first cable connecting the first cam and the loose end of the first limb, and a second cable connecting the second cam and the loose end of the second limb. ## Claims ### Claim 1 A crossbow, comprising: a frame along which a movement trajectory of an arrow substantially passes, a first limb and a second limb connected to the frame on opposite sides from the movement trajectory, each of said limbs having a loose end, a first cam having a first rotation axle and a second cam having a second rotation axle, said cams rotatably arranged on a first holder and on a second holder, respectively, said holders fixed on said frame on opposite sides from the movement trajectory, a bowstring connecting the first cam and the second cam, a first cable connecting the first cam and the loose end of the first limb, and a second cable connecting the second cam and the loose end of the second limb, wherein in both released and drawn states of the crossbow, the loose end of the first limb and the loose end of the second limb are located between the first rotation axle and the second rotation axle, and wherein only a projection of the bowstring to a plane of the crossbow crosses a projection of the movement trajectory to said plane. ### Claim 2 (depends on 1) The crossbow of claim 1, wherein the first cable is located completely on one side with the first cam relative to the movement trajectory, and the second cable is located completely on one side with the second cam relative to the movement trajectory. ### Claim 3 (depends on 1) The crossbow of claim 1, wherein each of the limbs consists of two or more limb portions. ### Claim 4 (depends on 1) The crossbow of claim 1, wherein the first holder and the second holder are made immovable when the bowstring is being drawn. ### Claim 5 (depends on 1) The crossbow of claim 1, wherein the first holder and the second holder are made movable, when the bowstring is being drawn. ### Claim 6 (depends on 1) The crossbow of claim 1, wherein the first holder and the second holder are made integral with the frame. ### Claim 7 (depends on 1) The crossbow of claim 1, wherein the first holder and the second holder are made separate from the frame. ### Claim 8 (depends on 1) The crossbow of claim 1, wherein t the first holder and the second holder are made as a single part. ### Claim 9 (depends on 1) The crossbow of claim 1, wherein, when the bowstring is drawn, the loose end of the first limb is located above the first cam, and the loose end of the second limb is located above the second cam. ### Claim 10 (depends on 1) The crossbow of claim 1, wherein, when the bowstring is drawn, the loose end of the first limb is located below the first cam, and the loose end of the second limb is located below the second cam. ### Claim 11 A crossbow, comprising: a frame along which a movement trajectory of an arrow substantially passes, a first limb and a second limb connected to the frame on opposite sides from the movement trajectory, each of said limbs having two loose ends, a first cam having a first rotation axle and a second cam having a second rotation axle, said cams rotatably arranged on a first holder and on a second holder, respectively, said holders fixed on said frame on opposite sides from the movement trajectory, a bowstring connecting the first cam and the second cam, at least one first cable connecting the first cam and said two loose ends of the first limb, and at least one second cable connecting the second cam and said two loose ends of the second limb, wherein said two loose ends of the first limb are located between the movement trajectory and the first rotation axle, and wherein said two loose ends of the second limb are located between the movement trajectory and the second rotation axle. ### Claim 12 (depends on 11) The crossbow of claim 11, wherein said at least one first cable is located completely on one side with the first cam relative to the movement trajectory, and said at least one second cable is located completely on one side with the second cam relative to the movement trajectory. ### Claim 13 (depends on 11) The crossbow of claim 11, wherein each of the limbs consists of two or more limb portions. ### Claim 14 (depends on 11) The crossbow of claim 11, wherein the first holder and the second holder are made immovable, when the bowstring is being drawn. ### Claim 15 (depends on 11) The crossbow of claim 11, wherein the first holder and the second holder are made movable, when the bowstring is being drawn. ### Claim 16 (depends on 11) The crossbow of claim 11, wherein the first holder and the second holder are made integral with the frame. ### Claim 17 (depends on 11) The crossbow of claim 11, wherein the first holder and the second holder are made separate from the frame. ### Claim 18 (depends on 11) The crossbow of claim 11, wherein the first holder and the second holder are made as a single part. ### Claim 19 (depends on 11) The crossbow of claim 11, wherein, when the bowstring is drawn, one loose end of the first limb and one loose end of the second limb are located above the first cam and the second cam, respectively, and the other loose end of the first limb and the other loose end of the second limb are located below the first cam and the second cam, respectively.
