Description

Heat cover for rackets.

Object of the invention

The present invention relates to a sheath for rackets, in particular for rackets or paddles provided with a rubber coating in your area or impact zones of the ball.

The object of the invention is also to achieve of the protection that for the racket implies its introduction in the inside a holster, keep said racket in optimum functional conditions, that is in optimal striking conditions of the ball.

Background of the invention

They are known covers for rackets and shovels that they usually have the common denominator to configure a practicable receptacle, usually through a zipper, which covers the racket to a greater or lesser extent and protects it against friction, bumps, etc., when it is out of use.

So, regardless of their structural features, the racket covers known so far they only offer the aforementioned benefit protective

On the other hand the rackets or shovels that incorporate the impact surface on the materialized ball in a rubber lining or other elastic material, they offer a optimal functionality at certain temperatures, so that the bouncing effect on the hit on the ball is impaired when the ambient temperature drops below a level pre-established, the performance being both lower of the racket the lower the temperature, which is precisely the temperature at which she is.

On the other hand, this problem also affects the player, since the performance of the racket from the moment When the game starts, they vary as it heats up by hitting the ball.

Description of the invention

The racket cover that the invention proposes solves the problem fully satisfactorily previously exposed, without prejudice to its classic benefits protective element of the racket against bumps, rubs and Similar.

To do this more concretely, the cover that the invention proposes, from the structuring of a cover Conventional for rackets, it focuses its characteristics on the fact that incorporates a heat generating element inside it, properly activated before starting the game, ensures that the Racket temperature is adequate at the time of such beginning, so that its effectiveness is optimal from the beginning of game.

In practice there are different alternatives for the materialization of the heat generating element, being able to use electrical resistors, well fed from the network or either of batteries or energy storage media existing in the own case and consequently rechargeable, or thermal bags reusable that constitute market elements capable of reach a temperature of the order of 50ºC, practically snapshot after activation, maintaining this temperature for a time between 2 and 3 hours.

In the case of using electrical resistors, these will be flat to fit the cover and the surface of rubber of the racket, and improve the thermal distribution on the latter, reaching in this case temperatures between 30 ° C and 40 ° C in a few minutes, the system can be activated / deactivated Racket heat generator with the frequency estimated timely.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a plan view of a Racket cover object of the present invention, in accordance with the example of practical realization for it in which it Use electrical resistors.

Figure 2.- Shows a profile of the cover of the previous figure.

Figure 3.- Shows a partial detail in section of the different layers of the cover and with the racket inside.

Figures 4, 5 and 6.- Correspond respectively with figures 1, 2 and 3, but in them appears the alternative in which the resistors have been replaced by bags Thermo-gel

Preferred Embodiment of the Invention

In view of the figures outlined and in particular of figures 1 to 3, can be seen as the cover that it is recommended that it is constituted by an envelope (1), of any conventional type, contour and thickness appropriate to the type of racket (2) to contain, in any case a racket or paddle (2) whose core is coated on both sides of respective layers rubber (3), envelope (1) equipped with classic means of access to inside, such as the zipper (4) that is observed particularly in figure 2.

To each major wall (5) of said envelope or cover itself, adapts and fixes a layer (6) of material insulator, to avoid thermal losses, and inside said layer insulator (6) is placed an electrical resistance (7) that remains retained with respect to the outer wall (5) with the collaboration of a grid (8) that allows heat to pass to the vane or racket (2).

The electrical resistors (7) located at both Racket sides (2) can be fed from the net by an appropriate plug head and also an appropriate element, or well the case can be totally autonomous incorporating batteries (9) rechargeable by a charger (10), leaving batteries and charger housed in a small receptacle (11) established in one of the walls of the envelope (1), preferably in one of their major faces and as seen particularly in the figure 2.

The heat generated by the resistance (7) is mainly concentrates on the palette (2) when passing directly through the grilles (8), while the thermal losses are nil thanks to the existence of a layer insulator (6) that internally covers each of the walls greater (1) of the cover or envelope.

As previously stated, in the Figures 4 to 6 have represented an alternative for the cover in issue in which the resistors (7) has been replaced by thermal bags (7 ') which, as previously stated, when they are activated generate an instantaneous temperature of the order of 50 ° C, which is mostly maintained for a time between 2 and 3 hours, once used bags can be reused introducing them in boiling water for 10 minutes approximately and letting them cool later.

Claims (4)
