- the sheath 23 is composed of several parts comprising a vertical portion joined to the base 18, a horizontal portion and a bend connecting the vertical and horizontal portions.
- the horizontal portion is composed of at least one piece, and preferably several parts assembled to allow adjustment of the length of the sheath 23 as needed.
- a pulley may optionally be positioned at the elbow of the sheath to maximize the efficiency of the return angle.
- the sheath 23 may also be embodied by a rod or bar, in this case the flexible element is outside the rod.

- Said blocker 28 is rotatably mounted about an axis of rotation similar to the main axis 5.
- said blocker 28 comprises a disk portion section in a direction perpendicular to its axis of rotation. Said disk portion possibly corresponding to a quarter circle.
- a first portion of the blocker 28 is preferably convex and forms an arc capable of repelling the targets 29 arriving by the supply ramp 27 without moving said targets 29 on said supply ramp 27.
- a second part of the blocker 28 is concave in an arc. The angle of the arc of said concave portion preferably corresponds to the angle of the convex arc formed by the outer portion of the targets 29.
- the use of the target launching machine starts with a first foot pressure on the arming pedal 20 which will, through the arming cable 21, rotate the arming pulley 8 in the counterclockwise direction.
- the claw 13 held in contact with the gearwheel 12 by a biasing member of the claw 30, preferably a torsion spring, drives it.
- the actuator 3 embodied in this embodiment by at least torsion springs begin to compress.

- the operations described above represent a possible and preferred embodiment of an arming cycle.
- the energy storage is effected by a plurality of arming cycles.
- Another advantage of the reiteration of this arming cycle also makes it possible to modify the amount of energy accumulated as a function of the desired projection distance or the number of projected targets.
- the realization of several cycles will have the effect of increasing the energy accumulated in the accumulator 6. This is embodied in this embodiment in particular by the deformation of the torsion spring or springs.
- this repetition of the movement of the user which is preferably but not limited to a pumping movement on the arming pedal 20, reduces the physical strength necessary for the use of the machine.
- the complete arming of the machine by a user without reiteration of the movement requires a considerable force.
- the use of the machine is open to users with less physical strength (children for example). The use is therefore simplified.
- the decrease in the force required to store energy allows for a machine that does not need an anchor in the ground to operate and has a lower total mass. Due to the separation between the actuator 3 and the frame 7 a contraction force is formed on the sheath 23 connecting the base 18 and the frame 7. The resistance of the sheath 23 must therefore be sufficient which increases the weight and the volume of the target launching machine. By reducing the torque necessary to actuate the actuator 3, the force on the sheath is all more reduced. Thus, the lightening of the mass and volume of the machine is directly related to the ability of the machine to operate through a repetition of a user's movement to arm a throw.
- an angular sector of the toothed wheel 12 is devoid of teeth in order to prevent the claw 13 from driving the toothed wheel 12 further. Therefore, any further pressure on the arming pedal 20 will remain without effect, which will preserve the mechanism.
- a supply ramp 27 capable of receiving a target 29. This shape is in the extension of the storage magazine containing one or more targets 29.
- the projection element 4 will rotate preferably between 90 and 135 degrees in the trigonometric direction. The inclination will cause the target 29 to move towards the launching ramp 26 while maintaining contact with the projection element 4.
- the blocker 28 located beyond the supply ramp 27 then opposes the displacement under the effect of the gravity of the target 29.
- the spring or torsion springs of the accumulator will cause by their relaxation a sudden rotation of the main axis 5 and the projection element 4.
- the target 29 will then slide along the launching ramp 26 and enter in contact with the end of the projection element 4 comprising the asperities. These will generate or accentuate a rotation of the target 29 on itself to obtain a uniform trajectory.
- the launch cycle ends with the projection element 4 in the horizontal position receiving a new target 29.
- Release of the trip pedal 19 allows the return spring of the trigger pulley 15 to return the trigger pulley 16 to its original position and thus release the arms and retention claws so that they enter from again in contact with the toothed wheel 12.
