Machine for tackle training, comprising: - a base comprising a guiding system and securing means which are designed for securing the base, - a slider which is mounted so as to be able to move in translation with respect to the guiding system in a direction of translation, between an extended position in which the slider is at its maximum extension out of the guiding system and a retracted position in which the slider is at its minimum extension out of the guiding system, and vice versa, - a dummy comprising: - a foot which is mounted so as to be able to move in rotation on the slider about a tipping axis perpendicular to the vertical plane parallel to the direction of translation between a locked position and an unlocked position and vice versa, - a frame which is mounted so as to be able to move in rotation on the foot about a tackling axis which is essentially parallel to the direction of translation when the foot is in the unlocked position, and - a block of foam which is attached to the frame and represents the opponent, - a blocking system which is able to move between a blocking position in which the slider is fixed in the extended position and a non-blocking position in which the slider is free to move towards the retracted position, and - a synchronization means which is designed to make the blocking system pass from the blocking position to the non-blocking position, when the foot passes from the locked position to the unlocked position. - a base comprising a guiding system and securing means which are designed for securing the base, - a slider which is mounted so as to be able to move in translation with respect to the guiding system in a direction of translation, between an extended position in which the slider is at its maximum extension out of the guiding system and a retracted position in which the slider is at its minimum extension out of the guiding system, and vice versa, - a dummy comprising: - a foot which is mounted so as to be able to move in rotation on the slider about a tipping axis perpendicular to the vertical plane parallel to the direction of translation between a locked position and an unlocked position and vice versa, - a frame which is mounted so as to be able to move in rotation on the foot about a tackling axis which is essentially parallel to the direction of translation when the foot is in the unlocked position, and - a block of foam which is attached to the frame and represents the opponent, - a foot which is mounted so as to be able to move in rotation on the slider about a tipping axis perpendicular to the vertical plane parallel to the direction of translation between a locked position and an unlocked position and vice versa, - a frame which is mounted so as to be able to move in rotation on the foot about a tackling axis which is essentially parallel to the direction of translation when the foot is in the unlocked position, and - a block of foam which is attached to the frame and represents the opponent, - a blocking system which is able to move between a blocking position in which the slider is fixed in the extended position and a non-blocking position in which the slider is free to move towards the retracted position, and - a synchronization means which is designed to make the blocking system pass from the blocking position to the non-blocking position, when the foot passes from the locked position to the unlocked position.
