Description

DESCRIPTION OF THE DRAWINGS

[0019] To complement the description being carried out and in order to assist to a best understanding of the characteristics of the invention, attached to this specification, as an integral part thereof, there is a set of drawings in which for illustrating and not limiting purpose the following has been represented:

[0020] The figure number 1.It shows a front view in perspective of an example of embodiment of the ball throwing machine, object of the invention, the main parts and elements it comprises can be seen, as well as its configuration and disposition; and

[0021] The figure number 2.It shows a rear view in perspective of an example of embodiment of the machine, allowing to see the rest of the parts and elements it comprises.

PREFERRED EMBODIMENT OF THE INVENTION

[0022] At the sight of the said figures, and according to the numbering adopted in them, a non-limiting example of the ball throwing machine of the invention can be seen which comprises the parts and elements that are stated and disclosed below.

[0023] Thus, as it can be seen in the FIG. 1, the machine (1) involved is configured, in a known manner, from a frame (2) with two rollers (3) that, operated by means of electric motors (4), rotate in opposite directions to shoot a ball (5) that is located between them, the said rollers (3) being linked to the frame (2) through a hinged joint (6) that allows to move them to vary their position with respect to the frame (2) and, so, the trajectory of the shoot.

[0024] From that already known configuration, the machine (1) is distinguished in that it comprises, essentially, means (7) to vary the position of the rollers (3) with respect to the structure (2), that can be locked by means of pushbuttons (8) to set the said position, which, preferably, consist in respective hydraulic springs (71) that, by one lower end are coupled to the hinged joint (6) and by a upper end, the opposite, they are coupled to a handle (9) that raises by the rear part of the machine (1), the opposite to which the shot is made by means of the rollers (3), and serving to manoeuvre it, the pushbuttons (8) that operate and lock, depending on whether pressing or not the said springs (71), being incorporated in the upper end of the said handle (9).

[0025] Preferably, the hinged joint (6) comprises three standard type joints matched so that they provide a triaxial movement, that means, a rotation joint towards both sides, a swinging joint upwards and downwards and a tilting joint towards one side and the other.

[0026] Also, in a preferred manner, the rollers (3) are protected within related shells (31), the machine (1) incorporating in addition suitable wheels (10) to facilitate its carriage and arranged, preferably, two in the front part of the base (21) of the frame (2), and a rotatory one in the rear part of the said base.

[0027] Anyway, according to another optional characteristic of the machine, the handle (9) is telescopically extensible allowing to incorporate up to, for example, five balls (5) to feed the throwing rollers (3).

[0028] Advantageously, the said handle (9) is formed by two extensible and parallel bars (91) that, ending in respective handgrips (92), determine a guide channel to hold the said balls (5) that, by gravity, are going down the rollers (3) located in their lower end.

[0029] The hydraulic springs (71) for setting the throwing position, are joined by their upper end to the middle area of the said bars (91) while the pushbuttons (8) that are connected by means of a related wiring (11) remain incorporated in the handgrips (92).

[0030] Also preferably, the machine (1) of the invention possesses a retaining mechanism (12) that controls the access of the ball (5) located downstream the handle (9) to the rollers (3) for it launching, the said mechanism (12) being linked to an electronic micro actuator, so that it can work, or by hand through a mechanical actuator (13) provided to that effect in the handle (9), or by means of a remote control device (not represented) that acts on a radiofrequency module provided to that effect in the said actuator.

[0031] Last, optionally, in the base (21) of the frame (2) the incorporation of a camera (14) has been provided, located at the front part of the machine, to record the user who receives the balls thrown by this machine.

[0032] The nature of this invention being sufficiently described, as well as the way of implementing it, it is not deemed necessary to further extend its explanation in order that any man of the art understands its extent and the advantages arising from it and it is pointed out that, within its essence, it can be implemented in other embodiments that differ in details from the one stated for example purpose and to which the protection sought shall extend provided that its fundamental principle is not altered, changed of modified.
