Definitions
- a quality table tennis table must meet. It must first offer a flat upper surface.
- the dimensions of such a tray are of the order of 140 x 150 cm, which implies using a material sufficiently rigid in itself so that it does not warp under its own weight when it rests on its feet, or to equip the underside of the tray with a stiffening frame or finally, as is most often the case, to achieve a compromise between the two.
- the plate must also allow a good rebound of the ball. This rebound depends on many factors which are due in particular to the surface condition of the table top (more or less tender nature of the coating, its roughness, etc.) and also to the mass presented by the portion of the table concerned by the impact. In fact, the denser a plateau, the better the rebound for a given ball.
- the plate is not subject to deformation because the expansions of the two metal sheets are substantially identical, the intermediate plastic material transmitting heat well, this plate does not have the qualities of density and stiffness on the surface required to ensure an acceptable rebound of the ball.
- Another metal table is also known in which an upper sheet forming a playing surface is associated with a lower sheet which has stamped shapes in the form of cups intended to stiffen it. The upper sheet is linked to the outside face of the cup bottoms by an agent sandwiched between them, this agent being a poor conductor of heat and sensitive to humidity.
- the dimensional stability of such a table is not satisfactory and, moreover, it has heterogeneities in its thickness such that the qualities of the rebound are very variable depending on the location of the impact of the ball.
- the price of this table places it at the top of the range of outdoor tables, which are already more expensive than indoor tables.
- the present invention intends to propose a table tennis table which optimally meets the requirements required for a good quality mobile table which can remain without any particular precautions outside.
- the subject of the invention is therefore a tray for a table tennis table, intended to be associated with a base and constituted by a thin panel and by a rigid metallic structure in the form of a frame at least. partial and fixed to one of the faces of the panel along at least three of its sides by means of a flexible adhesive material.
- a thin panel that is to say less than 15 millimeters has the advantage of being light compared to known panels. It involves associating it with a stiffening structure on the one hand to make it flat, because in the dimensions considered, its flatness cannot be guaranteed to be produced, and on the other hand to keep it flat.
- a flexible adhesive as a fixing means allows the two elements to play relative to each other without creating deformation, despite the small thickness of the panel.
- the structure is a complete frame whose cross member located under the edge of the panel forming the middle part of the standing table, is of reduced thickness.
- FIG 1 there is shown a corner of the panel 1 according to the invention and more specifically the corner that forms one of the side edges 2 of the table with the edge 3 of the panel which, the table assembled, is in the middle zone of this table, substantially under the net.
- the corner of the panel is shown turned over so that we can see its association with the frame 4 which, in its entirety, forms a frame associated with the panel by being glued to its underside 5 by means of a double adhesive tape. side 6 inserted between the frame 4 and the face 5.
- the panel 1 is made of a material known in itself which consists of a core comprising a plurality of superimposed sheets of kraft paper impregnated with a phenolic resin and two sheets of cover of kraft paper, also dyed in the mass and impregnated with a melamine resin, the whole being hardened or polymerized under pressure to form a laminated panel.
- This product has many properties, some of which are interesting for its use as a table tennis table. First of all it is a dense and stiff product which has a sufficiently polished surface to give a ball a good quality rebound even under a small thickness (of the order of 6 millimeters). The quality of the rebound will be all the better as the thickness is increased. It is therefore possible to have, in small thicknesses, a light panel providing an acceptable rebound.
- this product is completely chemically inert and has very high dimensional stability with regard to variations in humidity and temperature.
- the means of making such a panel planar resides in a metal frame-shaped frame.
- This frame can be obtained by folding sheet metal, or be tubular.
- the upright 7 of the frame visible in the figure is in the form of a sheet metal box folded in C.
- the frame can be complete, that is to say have four sides, or open then comprising only three sides, the side missing being that located to the right of edge 3 of the panel.
- the classic binding of a reinforcement under a panel implies the implementation of particular means which must not protrude above the playing surface, which imposes a significant thickness of the panel to have a sufficient anchoring length for the screws fixing and consequently increases the weight of the panel.
- the expansion coefficients of the panel and of the frame are different, a variation in temperature causes warping of the plate rigidly fixed to the frame.
- the fixing according to the invention by double-sided adhesive tape 6 made it possible to remove these obstacles. Indeed, the quality of the fixing no longer depends on the thickness of the panel which can be as thin as six millimeters. It is understood that, in this respect, the thinner the panel and the less the efforts to develop to keep it flat.
- the adhesive attachment therefore makes it possible to lighten the support structure and the weight gain takes place on the two components, panel and structure.
- the adhesive tape is a flexible and deformable material which allows a slight relative movement between panel and structure which is favorable to compensate for the effects of expansion or retraction of different amplitudes between structure and panel.
- the frame forming the structure of stiffening of the panel can be closed on its fourth side (to the right of the edge 3) by a cross member 9 of thickness thinner than the thickness of the other uprights.
- this crosspiece is connected to the panel by an adhesive tape 6 and to the ends of the uprights of the frame (for example by means of rivets 10 coupling it to a wing in return 11 of the upright).
- the cross member 9 is set back relative to the edge 3 because the lateral uprights such as 7 are shortened to allow the pinching on the edge of the plate of the net support members.
- the cross member 9 is of reduced thickness so as not to prevent the folding down of some of the feet articulated to the frame so that they extend parallel to the plate in the folded position.
- the arrangements of articulations of the base to the frame of the tray are known in themselves.
- FIGS 2 to 4 show an alternative embodiment of Figure 1 in which we find some of the elements already described with the same references.
- the lateral upright 7 of the frame visible in this figure has a return 12 instead of the tab 11.
- This return is connected to the end cross member of the frame by a secondary longitudinal upright 13 parallel to the upright 7.
- the return 12 as the secondary upright 13 will also be fixed to the panel 1 by a double-sided adhesive tape 6.
- the cross-member 9 is in this case fixed by riveting to the return 12 and to the panel by an adhesive tape 6.
- FIG. 4 shows a foot 14 articulated on the secondary upright 13 of the frame folded down along the internal face 5 of the panel 1 and parallel to the latter thanks to the low height of the cross-member 9.
- an adhesive can be used which retains a certain flexibility in the final state. They may, for example, be adhesives known commercially under the name of LOCTITE 326 or 380 (cyanoacrylate adhesive) or SILICOMET.
- the plate can be made of any synthetic material which can be manufactured in a thin, rot-proof plate and having mechanical surface qualities capable of obtaining an acceptable rebound for a table tennis ball. These include asbestos concrete, loaded resins, laminated structures ...
Abstract
Description
Les exigences auxquelles doit satisfaire un plateau de qualité de table de tennis de table sont de plusieurs ordres. Il doit tout d'abord offrir une surface supérieure plane. Les dimensions d'un tel plateau sont de l'ordre de 140 x 150 cm, ce qui implique d'utiliser un matériau suffisamment rigide en lui-même pour qu'il ne se gauchisse pas sous son propre poids lorsqu'il repose sur ses pieds, ou d'équiper la face inférieure du plateau d' une armature de raidissage ou enfin, comme c'est le cas le plus souvent, de réaliser un compromis entre les deux.There are several types of requirements that a quality table tennis table must meet. It must first offer a flat upper surface. The dimensions of such a tray are of the order of 140 x 150 cm, which implies using a material sufficiently rigid in itself so that it does not warp under its own weight when it rests on its feet, or to equip the underside of the tray with a stiffening frame or finally, as is most often the case, to achieve a compromise between the two.
Le plateau doit également permettre un bon rebond de la balle. Ce rebond dépend de nombreux facteurs qui tiennent notamment à l'état de surface du plateau (caractère plus ou moins tendre du revêtement, sa rugosité...) et également à la masse que présente la portion de table concernée par l'impact. En effet, plus un plateau est dense et meilleur est le rebond pour une balle donnée.The plate must also allow a good rebound of the ball. This rebound depends on many factors which are due in particular to the surface condition of the table top (more or less tender nature of the coating, its roughness, etc.) and also to the mass presented by the portion of the table concerned by the impact. In fact, the denser a plateau, the better the rebound for a given ball.
D'autres exigences découlent de l'usage auquel la table est destinée. Ainsi, si la table est transportable, elle doit être aussi légère que possible. Par ailleurs, si elle est destinée à une utilisation en plein air, elle doit pouvoir résister sans déformations temporaires ou permanentes, aux variations du taux d'humidité de l'air ou de sa température.Other requirements arise from the use for which the table is intended. So, if the table is transportable, it should be as light as possible. Furthermore, if it is intended for outdoor use, it must be able to withstand, without temporary or permanent deformation, variations in the humidity of the air or its temperature.
Aussi la table de tennis de table la plus difficile à construire, puisque devant satisfaire à toutes les exigences énoncées ci-dessus, est une table mobile pouvant séjourner longuement en plein air.Also the most difficult table tennis table to build, since it must meet all of the requirements set out above, is a mobile table that can stay outdoors for a long time.
Aucune des solutions connues ne donne pleinement satisfaction. On ne mentionnera que pour mémoire les tables d'extérieur en béton, puisqu'elles sont fixées à demeure au sol, bien qu'elles présentent un plateau qui soit indéformable et offrent d'excellentes qualités de rebond à la balle. Les autres tables comprennent celles à plateaux en bois ou produits de synthèse (aggloméré) issus du bois qui sont relativement lourds et sont très sensibles à l'hygrométrie de l'atmosphère, qui engendre des déformations indésirables. Il existe également des tables métalliques dans lesquelles le plateau est constitué par un produit plat composite comprenant un matériau plastique en sandwich entre deux feuilles d'aluminium et dont la raideur est assurée par un repli en retour des bords de la feuille sur au moins trois côtés. Bien que le plateau ne soit pas sujet aux déformations car les dilatations des deux feuilles métalliques sont sensiblement identiques, la matière plastique intercalaire transmettant bien la chaleur, ce plateau ne possède pas les qualités de densité et de raideur en surface requises pour assurer un rebond acceptable de la balle. On connaît également une autre table métallique dans laquelle une feuille supérieure formant surface de jeu est associée à une feuille inférieure qui possède des emboutis en forme de coupelles destinés à la raidir. La feuille supérieure est liée à la face extérieure des fonds de coupelle par un agent pris en sandwich entre eux, cet agent étant mauvais conducteur de la chaleur et sensible à l'humidité. La stabilité dimensionnelle d'une telle table n'est pas satisfaisante et, de plus, elle présente des hétérogénéités dans son épaisseur telles que les qualités du rebond sont très variables selon l'endroit de l'impact de la balle. En outre, le prix de cette table la place dans le haut de la gamme des tables d'extérieur, qui sont déjà plus chères que les tables d'intérieur.None of the known solutions gives full satisfaction. For the record, we will only mention the concrete outdoor tables, since they are permanently fixed to the ground, although they have a table that is non-deformable and offer excellent rebound qualities to the ball. The other tables include those with wooden trays or synthetic products (agglomerated) from wood which are relatively heavy and are very sensitive to the humidity of the atmosphere, which generates undesirable deformations. There are also metal tables in which the tray is constituted by a composite flat product comprising a plastic material sandwiched between two aluminum sheets and the stiffness of which is ensured by a backward folding of the edges of the sheet on at least three sides. . Although the plate is not subject to deformation because the expansions of the two metal sheets are substantially identical, the intermediate plastic material transmitting heat well, this plate does not have the qualities of density and stiffness on the surface required to ensure an acceptable rebound of the ball. Another metal table is also known in which an upper sheet forming a playing surface is associated with a lower sheet which has stamped shapes in the form of cups intended to stiffen it. The upper sheet is linked to the outside face of the cup bottoms by an agent sandwiched between them, this agent being a poor conductor of heat and sensitive to humidity. The dimensional stability of such a table is not satisfactory and, moreover, it has heterogeneities in its thickness such that the qualities of the rebound are very variable depending on the location of the impact of the ball. In addition, the price of this table places it at the top of the range of outdoor tables, which are already more expensive than indoor tables.
La présente invention entend proposer une table de tennis de table qui réponde de manière optimale aux exigences requises pour une table mobile de bonne qualité pouvant séjourner sans précautions particulières à l'extérieur.The present invention intends to propose a table tennis table which optimally meets the requirements required for a good quality mobile table which can remain without any particular precautions outside.
A cet effet, l'invention a donc pour objet un plateau pour table de tennis de table, destiné à être associé à un piètement et constitué par un panneau de faible épaisseur et par une structure rigide métallique en forme de cadre au moins partiel et fixée à l'une des faces du panneau le long d'au moins trois de ses côtés au moyen d'une matière adhésive souple.To this end, the subject of the invention is therefore a tray for a table tennis table, intended to be associated with a base and constituted by a thin panel and by a rigid metallic structure in the form of a frame at least. partial and fixed to one of the faces of the panel along at least three of its sides by means of a flexible adhesive material.
Un panneau de faible épaisseur, c'est-à-dire inférieur à 15 millimètres présente l'avantage d'être léger par rapport aux panneaux connus. Il implique de l'associer à une structure de raidissage pour d'une part le rendre plan, car dans les dimensions considérées, sa planéité ne peut être garantie de fabrication, et d'autre part lui conserver cette planéité. Pour tenir compte des différences de coefficient de dilatation du panneau et de l'armature, l'usage d'une colle souple comme moyen de fixation permet aux deux éléments de jouer l'un par rapport à l'autre sans créer de déformation, malgré la faible épaisseur du panneau.A thin panel, that is to say less than 15 millimeters has the advantage of being light compared to known panels. It involves associating it with a stiffening structure on the one hand to make it flat, because in the dimensions considered, its flatness cannot be guaranteed to be produced, and on the other hand to keep it flat. To take into account the differences in the expansion coefficient of the panel and the reinforcement, the use of a flexible adhesive as a fixing means allows the two elements to play relative to each other without creating deformation, despite the small thickness of the panel.
De manière préférée, la structure est un cadre complet dont la traverse située sous le bord du panneau formant partie médiane de la table dressée, est d'épaisseur réduite.Preferably, the structure is a complete frame whose cross member located under the edge of the panel forming the middle part of the standing table, is of reduced thickness.
L'invention sera mieux comprise par la description donnée ci-après d'un exemple de réalisation en référence aux dessins annexés dans lesquels:
- la figure 1 est une représentation d'un coin de plateau, vu de dessous, conforme à l'invention;
- la figure 2 illustre par une même vue une variante de réalisation;
- les figures 3 et 4 sont deux coupes selon les plans III-III et IV-IV de la figure 2.
- Figure 1 is a representation of a tray corner, seen from below, according to the invention;
- Figure 2 illustrates in a single view an alternative embodiment;
- Figures 3 and 4 are two sections along planes III-III and IV-IV of Figure 2.
Sur la figure 1, on a représenté un coin du panneau 1 selon l'invention et plus précisément le coin que forme l'un des bords latéraux 2 de la table avec le bord 3 du panneau qui, la table montée, se trouve dans la zone médiane de cette table, sensiblement sous le filet. Le coin de panneau est représenté retourné pour que l'on puisse voir son association avec l'armature 4 qui, dans sa totalité, forme un cadre associé au panneau en étant collé sur sa face inférieure 5 par le moyen d'un ruban adhésif double face 6 intercalé entre l'armature 4 et la face 5.In Figure 1, there is shown a corner of the
Le panneau 1 est en un matériau connu en lui-même qui se compose d'un noyau comprenant une pluralité de feuilles de papier kraft superposées imprégnées d'une résine phénolique et de deux feuilles de couverture en papier kraft, également teintées dans la masse et imprégnées d'une résine mélamine, le tout étant durci ou polymérisé sous pression pour former un panneau stratifié. Ce produit présente de nombreuses propriétés dont certaines sont intéressantes pour son utilisation comme table de tennis de table. Tout d'abord c'est un produit dense et raide qui présente une surface suffisamment polie pour conférer à une balle un rebond de bonne qualité même sous une faible épaisseur (de l'ordre de 6 millimètres). La qualité du rebond sera d'autant meilleure que l'épaisseur est augmentée. On peut donc disposer dans les faibles épaisseurs d'un panneau léger fournissant un rebond acceptable.The
En outre, ce produit est complètement inerte chimiquement et d'une très grande stabilité dimensionnelle à l'égard des variations du taux d'humidité et de la température.In addition, this product is completely chemically inert and has very high dimensional stability with regard to variations in humidity and temperature.
Cependant, l'inconvénient de ce produit réside dans le fait qu'on ne peut pas garantir sa planéité au sortir de sa fabrication. Son utilisation pour une table de tennis ne pouvait donc pas s'envisager, sans une adaptation ou un traitement du matériau pour lui conférer la planéité requise.However, the disadvantage of this product lies in the fact that one cannot guarantee its flatness at the end of its manufacture. Its use for a tennis table could not be envisaged, without an adaptation or a treatment of the material to give it the required flatness.
Selon l'invention, le moyen de rendre plan un tel panneau réside dans une armature métallique en forme de cadre. Cette armature peut être obtenue par pliage de tôle, ou être tubulaire.According to the invention, the means of making such a panel planar resides in a metal frame-shaped frame. This frame can be obtained by folding sheet metal, or be tubular.
Le montant 7 de l'armature visible sur la figure est en forme de caisson en tôle pliée en C. Le cadre peut être complet, c'est-à-dire comporter quatre côtés, ou ouvert ne comportant alors que trois côtés, le côté manquant étant celui situé au droit du bord 3 du panneau. La fixation classique d'une armature sous un panneau implique la mise en oeuvre de moyens particuliers qui ne doivent pas faire saillie au-dessus de la surface de jeu, ce qui impose une épaisseur importante du panneau pour disposer d'une longueur d'ancrage suffisante aux vis de fixation et en conséquence augmente le poids du panneau. Comme par ailleurs les coefficients de dilatation du panneau et de l'armature sont différents, une variation de température provoque un gauchissement du plateau fixé rigidement à l'armature.The upright 7 of the frame visible in the figure is in the form of a sheet metal box folded in C. The frame can be complete, that is to say have four sides, or open then comprising only three sides, the side missing being that located to the right of edge 3 of the panel. The classic binding of a reinforcement under a panel implies the implementation of particular means which must not protrude above the playing surface, which imposes a significant thickness of the panel to have a sufficient anchoring length for the screws fixing and consequently increases the weight of the panel. As, moreover, the expansion coefficients of the panel and of the frame are different, a variation in temperature causes warping of the plate rigidly fixed to the frame.
La fixation selon l'invention par ruban adhésif 6 double-face a permis de lever ces obstacles. En effet, la qualité de la fixation ne dépend plus de l'épaisseur du panneau qui peut être aussi mince que six millimètres. On comprend que, à cet égard, plus le panneau est mince et moins les efforts à développer pour le maintenir plan sont importants. La fixation adhésive permet donc d'alléger la structure de soutien et le gain de poids s'opère sur les deux composants, panneau et structure. En outre, le ruban adhésif est un matériau souple et déformable qui autorise un léger mouvement relatif entre panneau et structure ce qui est favorable pour compenser les effets des dilatations ou rétractions d'amplitudes différentes entre structure et panneau.The fixing according to the invention by double-sided
Il sera avantageux de prévoir une armature dont le contour est identique, pour trois côtés, au contour du panneau de manière que les flancs latéraux extérieurs tels que 8, des montants 7 de la structure soient sensiblement dans le plan des chants 2 correspondants du panneau. La largeur du ruban 6 sera légèrement inférieure à la largeur des montants 7 de manière à ne pas déborder ou effleurer le plan contenant les chants et les flancs. Cette disposition permet d'éviter une manipulation du plateau (notamment s'il est mis en oeuvre dans une table pliante) par préhension du seul panneau qui pourrait entraîner des sollicitations excessives de l'adhésif.It will be advantageous to provide an armature whose outline is identical, for three sides, to the outline of the panel so that the external lateral flanks such as 8,
On remarquera que le cadre formant structure de raidissement du panneau peut être fermé sur son quatrième côté (au droit du bord 3) par une traverse 9 d'épaisseur plus faible que l'épaisseur des autres montants. Dans le dessin, cette traverse est reliée au panneau par un ruban adhésif 6 et aux extrémités des montants du cadre (par exemple au moyen de rivets 10 l'attelant à une aile en retour 11 du montant). La traverse 9 est en retrait par rapport au bord 3 car les montants latéraux tels que 7 sont écourtés pour permettre le pincement sur le bord du plateau des organes de support du filet. La traverse 9 est d'épaisseur réduite pour ne pas empêcher le rabattement de certains des pieds articulés à l'armature afin que ceux-ci s'étendent parallèlement au plateau en position rabattue. Les dispositions d'articulations du piètement à l'armature du plateau sont connues en elles - mêmes.Note that the frame forming the structure of stiffening of the panel can be closed on its fourth side (to the right of the edge 3) by a
Les figures 2 à 4 représentent une variante de réalisation de la figure 1 dans laquelle on retrouve certains des éléments déjà décrits avec les mêmes références.Figures 2 to 4 show an alternative embodiment of Figure 1 in which we find some of the elements already described with the same references.
Le montant latéral 7 de l'armature visible sur cette figure possède un retour 12 aux lieu et place de la patte 11. Ce retour est relié à la traverse d'extrémité du cadre par un montant longitudinal secondaire 13 parallèle au montant 7. Ainsi, de chaque côté du plateau on forme deux cadres secondaires, dont les côtés intérieurs 13 pourront servir d'armature de fixation et/ou d'articulation pour le piètement de la table. Le retour 12 comme le montant secondaire 13 sera fixé également au panneau 1 par un ruban adhésif double face 6. La traverse 9 est dans ce cas fixée par rivetage au retour 12 et au panneau par un ruban adhésif 6.The lateral upright 7 of the frame visible in this figure has a
On voit sur la figure 4 un pied 14 articulé sur le montant secondaire 13 de l'armature rabattu le long de la face interne 5 du panneau 1 et parallèlement à cette dernière grâce à la faible hauteur de la traverse 9.FIG. 4 shows a
L'invention n'est pas limitée aux matériaux décrits dans l'exemple de réalisation exposé ci-dessus. En particulier, au lieu d'un ruban adhésif double face, on peut mettre en oeuvre une colle qui conserve à l'état final une certaine souplesse. Il peut s'agir par exemple d'adhésifs connus commercialement sous le nom de LOCTITE 326 ou 380 (adhésif cyanoacrylate) ou SILICOMET. Par ailleurs, le plateau peut être réalisé en tout matériau synthétique pouvant être fabriqué en plaque mince, imputrescible et possédant des qualités mécaniques de surface propres à obtenir un rebond acceptable pour une balle de tennis de table. On citera les bétons d'amiante, les résines chargées, les structures stratifiées...The invention is not limited to the materials described in the embodiment described above. In particular, instead of a double-sided adhesive tape, an adhesive can be used which retains a certain flexibility in the final state. They may, for example, be adhesives known commercially under the name of LOCTITE 326 or 380 (cyanoacrylate adhesive) or SILICOMET. Furthermore, the plate can be made of any synthetic material which can be manufactured in a thin, rot-proof plate and having mechanical surface qualities capable of obtaining an acceptable rebound for a table tennis ball. These include asbestos concrete, loaded resins, laminated structures ...
