    • The invention relates to a bow device (10) comprising a central part (11) with a handle part (20) for holding the bow as well as two projection limbs (12, 12'), one end of each of which adjoins the central part and the other end of each of which is connected to a string (17) of the bow. By attaching two deflection rollers (15, 15') to the central part which deflect the string (17) situated between the projection limbs towards the shooter when the bow is being tensed, the path followed by the string (17) when the bow (10) moves from a tensed state to a relaxed state has a length which is optimal for the acceleration of an arrow (21). Each limb (12, 12') can consist of two limb parts (12, 13, 12', 13') connected to each other by a connecting device (16, 16') in such a way that they can be detached.
    • 用片装置(10)和具有用于检测电弧的手柄部分(20)的中心部分(11)和两个投掷臂(12,12“),其各自的一个端部到相邻的中间部分,并且其另一端(与腱 17)被连接到电弧时,在片材的张紧期间其特征在于,在投掷臂之间的中央部分的两个导辊(15,15“)是固定的,其中偏转所述腱(17),用于保护出确保了弦的路径长度 (17)从所述薄片(10)的无应力状态下的片材(10)的夹紧状态具有用于沿箭头(21)的加速度的最佳长度。 每个腿(12,12“)可各自包括两个腿部(12,13,12”,13“)被组装,上述连接装置(16,16”)可拆卸地连接到彼此。
