DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) With reference to FIG. 1, a sport game footwear, 1, commonly used also by football referees, includes an upper, T, provided with lacing strings, and a sole, S, joined to said upper T along its profile, on which they can be inserted in a removable way or can be obtained some cleats. Said footwear 1, as evident in FIG. 2, is provided with a small tank, 11, filled with a pressure substance, 111, of the timed evanescence marker type, externally fixed to the upper T in the area behind it, while at the front, near the tip of the sole S, there is an opening, 12, connected, inside the footwear 1, to said tank 11 with connection means, 16. Said opening 12 is regulated in its operation by a check valve 121, as well operated by electromechanical actuation means 13, suitable for opening and closing on condition said check valve 121, and is adapted to spout said pressure substance 111 according to a predetermined direction. Said electromechanical actuation means 13 are located, in the hypothesis of greater comfort, inside the footwear 1, in the vicinity of said opening 12, and, presumably, comprise motorizing means, 131, the check valve 121, energy storage means, 132, of the rechargeable battery type, suitable for supplying said motorizing means 131, and at least one wireless receiving card 133, supplied by said energy storage means 132, and adapted to establish a remote connection with adjustment and control accessories. The tank 11 is also suitable to be filled and recharged with said pressure substance 111 by means of suitable instruments able to penetrate said tank 11 through a dedicated valve present on its outer surface. This way, at the end of a match or whenever necessary, it is possible to return tank 11 to the fullness regime and ensure the sufficient quantity of pressure substance 111 for at least one whole match. The energy storage means 132, of the rechargeable battery type, can be connected by means of suitable charging cables, to an external current supply source. This feature, together with the possibility of also recharging the tank 11, makes the footwear 1 durable and economical in the long term.

(7) FIG. 3 shows a clock, O, accessory of the embodiment of the invention, provided with suitable control means, 14, of the push-button type, which can be activated by pressure and suitable for operating remotely, by means of a wireless network card, 15, inside said clock O and univocally connected to the wireless receiving card 133 of the footwear 1, said electromechanical actuation means 13 of the footwear 1 itself. The wireless connection established between the wireless network card 15 and the wireless receiving card 133 is preferably of the Bluetooth type, but connections of the wi-fi type, infrared etc. are still valid and effective, provided they are always of the wireless type.

(8) FIG. 4 schematically shows the assembly of the elements included within the embodiment of the invention and clarifies the operating mechanism thereof. It is highlighted how a remote accessory, in this case the clock O, is able to communicate by means of the wireless network card 15, driven by the control means 14, with the wireless receiving card 133 of the electromechanical actuation means 13 contained within the footwear 1. The control means 15 can be activated by pressing the specific button present in the clock O, as weel as the other control buttons already existing in the clock O itself. The electromechanical actuation means 13, once the control signal is received, trigger the actuation of the check valve 121 which opens the passage of the pressure substance 111 allowing the jet spout through the opening 12. This way the pressure substance 111 is spout from the footwear 1 towards the surface of the playing field and it is thus allowed the referee to mark points or lines on the same field without having to bend to the ground and without having to use additional tools to be hold for all the time of match. This embodiment also makes it much easier to send the command, since the clock O is a necessary tool, always present at the wrist of a referee. The pressure substance 111 spout on the surface of the playing field, as previously specified, is of the timed evanescence marker type and for this reason its durability on the field is no more than about one minute.

(9) In a variant embodiment of the invention described above, the accessory on which the remote control means are installed is a simple button provided with a suitable wireless network card for the communication with the wireless receiving card present inside the footwear. The button is simply housed on any of the clothes the referee wears during the match. It can therefore be directly located on the shirt, on the shorts, on a wrist strap or even on the small register kept in the pocket. In this variant embodiment, like the previous one, the referee must simply press the button when the marking of the ground is requested and keep the tip of the footwear with the opening facing the surface of the field.

(10) An advantageous variant embodiment of the invention described above provides for the possibility of removing and replacing the tank with one of the same type. This way, when the tank is empty or does not have enough pressure substance to start a new match, the empty tank is replaced by a full tank without having to resort to additional external equipment to carry out the recharge. This feature therefore allows the referees themselves to be able to easily carry out the replacement in complete autonomy. In this case the tank is provided with quick coupling and releasing elements to the body of the footwear which can advantageously be of a pressure type.

(11) In a further variant embodiment, the connection means between the tank and the opening are located outside the footwear and more precisely below the outer profile of the sole. This way, it is exploited the available space between the playing field and the lower profile of the sole, thus existing thanks to the fact that the footwear cleats allow it to remain slightly raised with respect to the ground. Alternatively, the passage of the connection means always takes place outside the footwear but superficially along the upper.

(12) In a further variant of the described embodiment, the tank is located at the front near the tip of the footwear and the opening is located on the outer surface of the tank in such a way that the connection means are not necessary but instead it is possible to spout the pressure substance directly from the tank through the opening itself. The latter remains in any case operated by the same check valve, which can be controlled by the same electromechanical actuation means, remotely controlled by the control elements themselves, and communicated with them always in wireless mode. In this embodiment, less cumbersome and more economical, each element of the invention installed on the footwear is located near the tip, and therefore it is allowed greater freedom in use and in the eventual decoration of the footwear.

(13) In a variant embodiment there is a specific application inside the clock software for the management and real-time display of the quantity of pressure substance present inside the tank. This way the referee is able to immediately know the pressure substance level and then evaluate a possible recharge of the same.

(14) The above and further variations and modifications of practical application nature may of course be provided, while still remaining within the scope of protection defined by the claims below.
