Device for launching a projectile or a launch object in general, comprising: a stock having a longitudinal development direction between a rear or proximal end and a front or distal end; at least two bending members associated to said stock on opposite sides of it and having a preferential development direction, said bending members being apt to be subjected to bending in order to accumulate and supply energy usable to launch said projectile, and released in a rest condition; tensioning means of said bending members; pushing means of said projectile apt to cooperate with said bending members. Said tensioning means comprise at least two cams arranged on opposite sides of the stock, each of which is pivoted at a respective first axis of rotation and is associated to at least one corresponding bending member, so that an angular displacement of said cam around said first axis of rotation determines a bending action on said at least one corresponding bending member. Said pushing means comprise at least two arms arranged on opposite sides of the stock and connected to each other through a flexible member, wherein each of said arms has a first end pivoted at a second axis of rotation and a second end apt to support a portion of said flexible member. Each of said arms is operatively connected to a respective cam, so that a rotation of each arm in a first rotation direction determines a bending of said bending members by means of the cam during a loading phase of the device and that, during a launch phase of said projectile, a return of the bending members towards said rest condition determines, by means of the cam, a rotation in the opposite direction of each arm.
