Abstract

Table tennis racket comprised of a plate (1) of conventional size whose edge may be thicker (3). The assembly is covered by an elastic membrane (7) which allows, by its thightening in a groove (4) on the contour of the plate, to obtain a variable tension surface and consequently a different rebound quality. By pulling the strip by means of a knurled (13) screw (11) system situated in the handle (2) of the racket, it is possible to adjust the tension of the membrane (7). When the ball rebounds, the membrane (7) is depressed till it touches the plate (1) or the foam layer (6) lining the plate, and expands elastically conferring the desired effect to the ball.

Description

Baquette de tennis de table à surface de rebond membranaire, à rapidité et contrôle modifiable  Table tennis bench with membrane rebound surface, speed and modifiable control
La présente invention concerne une raquette de tennis de table ou de type apparenté, dont le revêtement (constitué d'une membrane tendue selon le choix du loueur) permet de changer la qualité du rebond de la balle, ou de lui donner des effets inédits.  The present invention relates to a table tennis racket or similar type, the coating (consisting of a stretched membrane according to the choice of the rental company) can change the quality of the bounce of the ball, or give it new effects.
Cette invention appartient au domaine du jeu de tennis de table, ou de type apparenté, tel le ping-pong.  This invention belongs to the field of table tennis, or related type, such as table tennis.
Jusqu'à présent les raquettes en usage dans ce domaine, sont constituées d'un bâtis rigide sur lequel sont collées une ou plusieurs couches fixées (voire amovibles) de mousse ou d'un picot élastique, ne permettant au plus que deux qualités de rebonds (une pour chaque face)  Until now, snowshoes in use in this area have consisted of a rigid frame onto which one or more fixed (or even removable) layers of foam or an elastic spike are glued, allowing at most only two rebound qualities. (one for each side)
Le joueur, très sensible aux paramètres caractérisant la qualité du rebond, se trouve généralement contraint à un choix limité dans les caractéristiques de la raquette, qui sont essentiellement reliées aux types de surfaces ainsi qu'à l'épaisseur de celles-ci  The player, very sensitive to the parameters characterizing the quality of the rebound, is generally constrained to a limited choice in the characteristics of the racket, which are essentially related to the types of surfaces as well as to their thickness.
De plus, une fois la raquette choisie, le joueur ne peut pratiquement plus modifier ces caractéristiques qu'en recollant de nouvelles couches de revétement, ce qui reste contraignant et peu aisé.  In addition, once the racket has been chosen, the player can practically no longer modify these characteristics except by sticking on new layers of coating, which remains restrictive and not very easy.
On peut enfin remarquer la stagnation relative de l'état de la technique, par rapport aux raquettes de tennis par exemple .  We can finally note the relative stagnation of the state of the art, compared to tennis rackets for example.
La présente invention consiste en un dispositif simple et efficace, qui permet d'offrir des possiblitès nouvelles, en matière de rebond et de toucher de balle, en proposant un type de surface de raquette adaptable selon les propres critères du joueur et â tout moment par simple réglage. L'ensemble du corps de la raquette garde les dimensions standard, mais s'écarte des modèles conventionnels par les spécifications suivantes ;  The present invention consists of a simple and effective device, which makes it possible to offer new possibilities, in terms of rebound and touching the ball, by proposing a type of racket surface adaptable according to the player's own criteria and at any time by simple adjustment. The whole body of the racket keeps the standard dimensions, but deviates from conventional models by the following specifications;
La raquette comporte un plateau qui peut être plus fin que la normale, mais dont la circonférence fait un débordement par rapport au niveau de la surface du plateau. Une ou plusieurs rainures profonde de quelques millimètres et peu large y sont creusées sur le pourtour, dans la tranche du plateau. On peut encore utiliser un rebord profilé séparément puis accolé a/dans la tranche. Une membrane légèrement élastique vient envelopper la raquette (totalement ou sur une seule face), manche excepté. Cette membrane se trouve tendue par serrage d'un ruban, qui vient s'enchâsser par dessus, dans la gorge du plateau . Le système de serrage, relie au ruban, peut par exemple être constitué à l'aide d'une vis moletèe, localisée dans le manche de la raquette The racket has a plate which can be thinner than normal, but the circumference of which extends beyond the level of the surface of the plate. One or more grooves a few millimeters deep and not very wide are dug around the periphery, in the edge of the tray. It is also possible to use a separately profiled rim then attached to / in the edge. A slightly elastic membrane wraps the racket (totally or on one side), except the handle. This membrane is stretched by tightening a ribbon, which is embedded over it, in the throat of the plateau. The clamping system, connected to the tape, can for example be formed using a knurled screw, located in the handle of the racket
Selon une première variante, la membrane élastique recouvre l'ensemble du plateau en laissant dans l'entre deux une nappe d'air, qui permet au moment du rebond, de faire jouer transversalement l'élasticité en fonction du serrage  According to a first variant, the elastic membrane covers the whole of the plate, leaving an air layer in between, which allows the elasticity to act transversely at the moment of the rebound as a function of the tightening.
Selon une seconde variante, une couche fine de mousse ou de matériau élastique se trouve collée ( sur le plateau de la raquette bord non compris) en dessous de la membrane, et/ou sépare d'elle par une couche d'air de faible épaisseur. Le rebond est ici fonction de l'écrasement de la mousse.  According to a second variant, a thin layer of foam or elastic material is bonded (on the racket with the edge not included) below the membrane, and / or separated from it by a thin layer of air. . The rebound here is a function of the crushing of the foam.
Selon une troisième variante, combinable aux versions précédentes, un patin de matière élastique ou un picot conventionnel est collé sur la membrane tendue, pour donner un meilleur toucher de balle.  According to a third variant, which can be combined with the previous versions, a pad of elastic material or a conventional spike is glued to the stretched membrane, to give a better ball feel.
selon une quatrième variante, le rebord est affèrant a la surface du plateau, par exemple si l'épaisseur de membrane suffit à elle seule à la qualité rebond. Quelque soit la variante, le changement de tension entraine un amincissement et simultanément un durcissement de la membrane, qui modifie ici directement la "rapidité" de la surface. On peut remarquer que suivant le profil considéré, on peut atteindre des variations de surface de la membrane de l'ordre de 25 % et donc une gamme de tension large  according to a fourth variant, the edge is afferrant to the surface of the plate, for example if the thickness of the membrane alone is sufficient for the rebound quality. Whatever the variant, the change in tension leads to a thinning and simultaneously a hardening of the membrane, which here directly modifies the "speed" of the surface. It can be noted that depending on the profile considered, it is possible to reach variations in the surface of the membrane of the order of 25% and therefore a wide voltage range.
Selon une cinquième variante, une membrane fine et très adhérante sur sa face externe, en matériau super élastique recouvre la membrane principale, cette dernière améliorant substantiellement le rebond alors que la première confère â la balle un mouvement de rotation accru par son mouvement de glissement latéral, permettant ainsi des effets inédits.  According to a fifth variant, a thin and very adherent membrane on its outer face, made of super elastic material covers the main membrane, the latter substantially improving the rebound while the first gives the ball a rotational movement increased by its lateral sliding movement. , allowing unique effects.
Selon une sixième variante, les deux faces de la raquette sont différenciées, selon un choix de combinaison parmi les variantes précédentes.  According to a sixth variant, the two sides of the racket are differentiated, according to a choice of combination from the preceding variants.
Selon une septième variante , la membrane peut être constitué en plusieurs parties spécifiques, par exemple dans leur elasticte ou épaisseur, ou dureté; afin de les adapter aux différentes fonction de rebond, de serrage et â l'encolure du manche Le corps de la raquette peut être constitué en bois, ou plus avantageusement dans un (à plusieurs) matériau(x) facilement usinables tels que l'aluminium, des plastiques ou des matériaux composites , présentant une grande résistance aux effets mécaniques qui s'exercent sur certaines parties de la raquette (bordure du plateau ou manche en particulier). According to a seventh variant, the membrane can be made up of several specific parts, for example in their elasticity or thickness, or hardness; in order to adapt them to the different rebound, tightening and neck neck functions The body of the racket can be made of wood, or more advantageously of one (or several) easily machinable material (s) such as aluminum, plastics or composite materials, having great resistance to the mechanical effects which are exerted. on certain parts of the racket (edge of the plate or handle in particular).
Selon un mode de réalisation particulier du système de tension de la membrane, le ruban de serrage se trouve introduit dans le manche de raquette symétriquement de chaque coté et est tiré à l'aide d'une vis moletêe montée sur pivot. Un boulon monté sur le filetage permet, lors du vissage, de tendre le ruban pinçant la menbrane dans le pourtour du plateau .  According to a particular embodiment of the membrane tensioning system, the tightening tape is inserted into the racket handle symmetrically on each side and is pulled using a knurled screw mounted on a pivot. A bolt mounted on the thread makes it possible, during screwing, to tighten the ribbon pinching the menbrane around the edge of the plate.
L'invention sera mieux comprise en se référant aux dessins annexés représentant, à titre d'exemple, une forme de réalisation de la raquette selon les principes exposés.  The invention will be better understood by referring to the accompanying drawings showing, by way of example, an embodiment of the racket according to the principles set out.

les figures 1-2-3 représentent le dispositif selon son principe dans un mode de réalisation simple  Figures 1-2-3 show the device according to its principle in a simple embodiment
Le plateau (1) constituant le corps de la raquette, forme avec la coque du manche (2) un châssis d'un seul tenant. Sur le pourtour du plateau (1), un rebord (3) épaté d'une largeur de l'ordre de 15 mm pour fixer une idée, fait saillie de chaque côté de la raquette ; une ornière centrale (4) est creusée dans le rebord (3) en son milieu sur une profondeur de quelques millimètres. Sur chaque face (6) du plateau (1), des patins (6) de mousse de l'ordre du mm d'épaisseur sont accolés Une menbrane (7) semi-elastique vient gainer l'ensemble du plateau (1) sur le bord duquel elle s'appuie (4). Une fente (10) pratiquée dans le haut du manche (2) permet le recouvrement quasi total du plateau. Une nappe d'air (11) se trouve ainsi emprisonnée entre les patins de mousse (6) et la membrane (7), permettant â celle ci de faire louer son élasticité au moment du choc avec la balle . Le ruban (5) de serrage de la membrane (7) vient enchâsser celle ci dans la rainure (4) du rebord (3) du plateau (1) . Une vis (11) moletêe (13) prenant appui sur une cullèe (8) et enchâssée dans le manche (2), permet, par rotation de la molette (13), de tirer sur le collet formé par le ruban de serrage (5), et les pivots (14) bordés par un ècrou (9) pouvant coulisser dans la chambre (12)par rotation de la molette (13) The plate (1) constituting the body of the racket, forms with the shell of the handle (2) a frame in one piece. On the periphery of the plate (1), a flat edge (3) with a width of the order of 15 mm to fix an idea, protrudes on each side of the racket; a central rut (4) is hollowed out in the rim (3) in the middle over a depth of a few millimeters. On each face (6) of the plate (1), pads (6) of foam of the order of a mm of thickness are placed side by side A semi-elastic menbran (7) sheaths the entire plate (1) on the edge of which it rests (4). A slit (10) in the top of the handle (2) allows almost total recovery of the plate. An air layer (11) is thus trapped between the foam pads (6) and the membrane (7), allowing the latter to rent its elasticity at the time of impact with the ball. The ribbon (5) for clamping the membrane (7) is encased in the groove (4) of the flange (3) of the plate (1). A knurled screw (11) (13) resting on a wedge (8) and embedded in the handle (2), allows, by rotation of the knurl (13), to pull on the collar formed by the tightening tape (5 ), and the pivots (14) bordered by a nut (9) which can slide in the chamber (12) by rotation of the thumb wheel (13)
Le principe de base reposant sur la notion de tamis membranaire permet donc une grande variété de paramètres de rebonds de la balle sur la raquette tels : rapidité, contrôle, effets sur la balle ..., facilement modifiables par le joueur. Celui ci peut donc adapter une raquette selon son tempérament ou son humeur Le châssis de la raquette peut facilement être fabriqué en bois menuisé puis colle ou par exemple, en accolant une bordure en plastique moule sur un bois traditionnel réadapté.  The basic principle based on the notion of membrane sieve therefore allows a wide variety of parameters of bouncing of the ball on the racket such as: speed, control, effects on the ball ..., easily modifiable by the player. This one can therefore adapt a racket according to his temperament or his mood. The frame of the racket can easily be made of carved wood then glue or for example, by attaching a molded plastic border on a traditional readjusted wood.
