FR2640150A1 - Modular and removable panel for playing tennis by oneself - Google Patents

Abstract

The invention relates to a panel for playing tennis, giving a more or less random rebound of the ball. It consists of a decorative design with variable reliefs 3, 4, 5, 6. It may be equipped with a device for allocating and displaying the points scored. The panel according to the invention is intended for sports games.

Description

The present invention relates to a removable and modular panel characterized in that it causes a more or less random rebound of the game ball.
In the usual situation of playing solo tennis against a pediment, a built wall, or a garage door; it follows that the rebound of the ball is subject to the law of reflection, that is to say that the rebound angle (ss) of the ball is equal to the angle of incidence () Fig.I.

 Therefore, the player can more or less easily understand the return area of the ball in view of the angle of incidence that it will have upon impact on the wall.

The removable panel which is the subject of the present invention and which will be described hereinafter 2 essentially for the purpose of increasing the share of uncertainty in the bouncing zone of the ball and thereby enriching the playfulness a game of tennis alone,
According to a preferred but not exhaustive configuration, this removable and modular panel (1) Pig. 2 will be rectangular in shape, the impact face (2) of which has a decorative pattern having a variable relief resulting from a positioning of plane facets (3 ), oblique (4), concave (5), convex (6) as shown in section Fig. 3.

I1 thus results that for a same angle of incidence oc of the ball, and according to the impact zone a multitude of angles of rebounds in relation to the game plan.
In a preferred embodiment, Fig.5 shows a panel whose relief and decorative pattern correspond to the image of an opposing player thus giving the impression of a game of duet and being more attractive.

 es fiv. 6,7,8 represent panels whose relief and decorative motif correspond to products of common utility: edible ice, drinks, car.

 Fiv. 9 represents a panel with a naturei site motif with trees and greenery (7).

 a Fig. IO represents a natural mountain site with a lake or sea shore (8, '.

 These different patterns have the particularity of being able to be juxtaposed at the option of the player and yet ensuring continuity and homogeneity of the decorative frame as shown in Fig.II.

 According to a more elaborate variant, the panel can be provided with a device for allocating points in the event that the ball hits a predeter ~ born area.

 Fig.I2 represents a humorous character (9) whose nose (IO) communicates with a point display device (II) by mechanical, electrical or pneumatic means known in this kind of game apparatus. A point totalizer can be added as well as any electronic motif with light effects and / or wasicPux (I7).

 The panel will be made of a sufficiently rigid material to allow a correct rebounding of the ball, such as a molded or thermoforced plastic material presented in soup Fig.I3. Laminate coated with synthetic resin is also suitable. The back side can be filled with a light material (I2) such as compacted wood or synthetic foam. Raldissage fabrics (I3) assure a geometrical rigidity to the unit, which, associated with the filling product also attenuate the noise. he panel is fitted with holes (I4) or any other fixing means. The impact face is decorated and painted with colors appropriate to the pattern shown.

 In order to vary the rebound effect of the game ball, the impact face can be provided with zones with variable reflecting power such as an elastic mattress (I5) having the particularity of absorbing part of the energy of percussion, and to considerably attenuate the rebound of the ball.

 the front face of the panel may be translucent in whole or in part and be tinted with different colors (I8) appropriate to the subject shown in Fig.I4.

 To such a panel can also be added a light effects control device (I6) interconnected with heath axes (20) and the impact information of which is supplied by probes (I9) reacting to the shock such as a polyvinylidene fluoride (PVF 2) piezoelectric polymer.

 The removable panel according to the invention is intended for sports games.
