DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention has for its object an electromechanical training apparatus for launching balls, particularly footballs.
BACKGROUND OF THE INVENTION
The state of the art can be defined by the following patents:
FR-A-2,334.381 "Process for launching footballs toward a predetermined emplacement, characterized by the fact that the balls are withdrawn from a supply, mechanically or by gravity, they are dispatched one by one to a launching station and are launched by applying to the desired position a blow whose force is adjustable. There is applied to the ball a blow oriented as desired horizontally or upwardly. The position of the point of impact on the ball can be modified over a range comprised between the horizontal median plane of the ball and the plane passing through the center of this ball and making with this horizontal plane a downward angle greater than 30.degree.. The percussion is graded by a plunger having substantially the length of the leg and oscillating in the manner of a lever. The apparatus comprises a supply of balls, a device for emplacing these balls, which opens at the launching station, and a percussion mechanism, as well as a control apparatus for this emplacement device and of this mechanism."
FR-A-2.433.956: "Apparatus comprising according to the principal patent a supply, a launching station and an emplacement device permitting removing balls from the supply and placing them individually in the launching station, this apparatus comprising moreover a striking mechanism and a control apparatus adapted to permit the launching of the balls with a force whose intensity is adjustable and whose point of impact on the ball can be selected. The device is mounted on a pivoting lever, the pivoting of this lever permitting adjusting the position of the percussion mechanism relative to the ball. Use for training football players."
FR-A-2.409.059: "Apparatus for launching balls characterized in that it comprises a tube provided at one of its ends with an opening of a section greater than the size of the balls to be launched, as well as a supply device connected to a supply of balls adapted to introduce a ball into the tube, the tube enclosing an expulsion device adapted to expel the ball from the tube at a given moment and under predetermined conditions."
FR-A-2.580.507: "The invention relates to sporting equipment. The device which is the object of the invention is characterized particularly in that the synchronization mechanism for the movements of the pusher and the striker comprise a crank connected mechanically to the pusher and mounted on a drive shaft supported by the base, disposed substantially parallel to the control shaft and turning in a direction opposite to the latter, the crank being movable in rotation, conjointly with the drive shaft and at the speed of this latter, as well as at a speed higher than this latter during the displacement of a ball by the pusher toward the striking position. It is advantageous to use the device in question to launch balls or the like for training particularly tennis players, football players, hockey players."
FR-A-2.577.813: "The invention relates to sporting equipment. The device which is the object of the invention is characterized in that it comprises a chamber for the securement of balls or the like, in striking position, connected to the separator, communicating with this latter, enclosing the pusher and formed by lateral walls, an upper wall and a lower wall, one of said lateral walls being disposed on one side of the plane of angular displacement of the striker, transversely to the control shaft, while the function of the lateral wall opposite to the lateral wall is fulfilled by the pusher in the course of the securement of the balls or the like and said walls of the chamber being traversed by openings for entry and exit of the striker and for the passage of the balls or the like that are launched. The device in question can be used particularly for training tennis players, football players, hockey players."
