Abstract
Description
La présente invention concerne un support tournant pour plateau de table circulaire destiné à ètre installé au centre d'une table ronde. The present invention relates to a rotating support for a circular table top intended to be installed in the center of a round table.
Ces tables rondes à plateau central tournant-sont d'origine chinoise et très répandues de nos jours en extrème-
Orient. Traditionnellement ces grandes tables sont construites entibrement en bois . Le plateau central est relié en son centre å un demi-arbre assez long pour atteindre le sol ou il repose sur une crapaudine. Cet arbre passe par un trou central de la table ronde avec un faible jeu,formant ainsi le palier de guidage supérieur du demi -arbre . En veillissant,cet assemblage rustique a une facheuse tendance à la dislocation.These round tables with central turntable - are of Chinese origin and very widespread today in the extreme -
East. Traditionally these large tables are built entirely of wood. The central plate is connected in its center to a half-tree long enough to reach the ground where it rests on a basket. This shaft passes through a central hole in the round table with little play, thus forming the upper guide bearing of the half-shaft. By taking care, this rustic assembly has an annoying tendency to dislocation.
Malgré tous les renforts on constate que ce mobilier est généralement assez branlant. Despite all the reinforcements we see that this furniture is generally quite shaky.
La présente invention a pour but de proposer une solution originale permettant
I) L'adaptation d'un unique type de support tournant à toutes les tables rondes , Quelque soit leur matière ou épaisseur.The object of the present invention is to propose an original solution allowing
I) The adaptation of a single type of rotating support to all round tables, whatever their material or thickness.
2) L'indestructibilité de ce support tournant,tant-par la surcharge du plateau tournant,que la corrosion du mécanisme.2) The indestructibility of this rotating support, both by the overload of the turntable, and the corrosion of the mechanism.
3) La grande douceur de rotation du plateau tournant.3) The great smooth rotation of the turntable.
4) L'extrême facilité de la pose du mécanisme.
Cette invention doit permettre une commercialisation de tables rondes monumentales à plateau central tournant encore peu connues et utilisées en'Europe. Par la diffusion du mécanisme seul, chacun peut transformer une grande table ronde en "table chinoise".4) The extreme ease of installing the mechanism.
This invention should allow the commercialization of monumental round tables with a central turntable still little known and used in Europe. By diffusing the mechanism alone, everyone can transform a large round table into a "Chinese table".
Bien entendu la présente invention n'est pas limitée à cet usage précis ni aux modes de réalisation décrits. Of course, the present invention is not limited to this specific use or to the embodiments described.
Elle est susceptible de variantes accessibles à l'homme de l'art sans que l'on s'écarte de l'esprit de l'invention. It is susceptible of variants accessible to a person skilled in the art without departing from the spirit of the invention.
Le support de plateau tournant est composé de deux organes principaux : l'un fixe et l'autre mobile.The turntable support is made up of two main parts: one fixed and the other mobile.
A titre d'exemple la partie fixe est composée d'une platine en acier inoxydable de 140 mm de diamètre, épaisseur 3 mm avec un trou central de 32 mm de diamètre. Cette platine a sa face supérieure polie et porte sur sa face inférieure trois écrous soudés M IO recevant trois tiges filetées verticales.For example, the fixed part consists of a stainless steel plate 140 mm in diameter, 3 mm thick with a central hole of 32 mm in diameter. This plate has its polished upper face and carries on its lower face three welded nuts M IO receiving three vertical threaded rods.
Ces tiges filetées sont munies d'écrous et de rondelles frein pour maintenir parallèles deux paliers à billes de 30 mm du type à plaques. Ce roulement à bille particulier a sa cage extérieure sphérique et oscille dans un logement constitué de deux plaques de tôle emboutie percées de trois trous équidistants. L'entre-axe des tiges filetées correspond à l'entre-axe de ces trous. Ces roulements graissés à vie ont un dispositif de bloquage surl'arbre par pression d'une vis allen.These threaded rods are provided with nuts and lock washers to keep two 30 mm ball bearings of the plate type parallel. This particular ball bearing has its spherical outer cage and oscillates in a housing consisting of two stamped sheet metal plates pierced with three equidistant holes. The center distance of the threaded rods corresponds to the center distance of these holes. These bearings greased for life have a locking device on the shaft by pressing an allen screw.
Pour protéger ces paliers de la poussière et surtout de l'oxydation un couvercle d'acier,en forme de casserole dont le fond est perce de trois trous à l'entre-axe pré-cité est enfilée sur les tiges filetées . Le diamètre ext. To protect these bearings from dust and above all from oxidation, a steel cover, in the shape of a pan, the bottom of which is drilled with three holes at the above-mentioned center distance, is threaded onto the threaded rods. The ext.
du couvercle est le même que celui de la platine.of the cover is the same as that of the plate.
La table sur laquelle on veut fixer le support tournant doit ètre percée d'un trou central de I20 mm de diamètre par ou est introduit l'organe fixe avec interposition d'un joint de caoutchouc. le couvercle est en'suite boulonné sous la table avec interposition également d'un joint d'étanchéité. The table on which we want to fix the rotating support must be pierced with a central hole 120 mm in diameter through which the fixed member is inserted with the interposition of a rubber seal. the cover is then bolted under the table with the interposition of a seal.
Ces écrous doivent ètre étanchés à l'aide d'une pâte à joints par exemple.These nuts must be sealed using a joint compound for example.
Cet ensemble platine,roulements à plaque, entretoises et couvercle n'a de rigidité qu'une fois serré sur la table. This set of plate, plate bearings, spacers and cover has rigidity only when tightened on the table.
Celle ci tient lieu de corps au double palier ainsi constitué.This takes the place of a body at the double level thus formed.
La partie mobile du support tournant est composée d'un moyeu fait d'un disque cylindrique en acier qui ioe mm e=IO mm soudé sur un arbre 30-mm et dont la longueur sera fonction de l'épaisseur du plateau fixe de la table ronde. L'ensemble arbre et moyeu est usiné après soudure,pour avoir une parfaite géométrie. Le moyeu porte 4 bras ou plus , soudés sur la tranche cylindrique du moyeu. Ces bras 1= 500 mm sont en acier IOx20mm d'une nuance permettant flexibilité et soudabilité. The movable part of the rotating support is composed of a hub made of a cylindrical steel disc which ioe mm e = IO mm welded on a 30-mm shaft and whose length will depend on the thickness of the fixed table top round. The shaft and hub assembly is machined after welding, to have a perfect geometry. The hub has 4 or more arms welded to the cylindrical edge of the hub. These arms 1 = 500 mm are made of IOx20mm steel of a grade allowing flexibility and weldability.
Ces bras sont munis sur leur face supérieure de pièces anti-dérapantes en forme de pastilles par exemple pour recevoir la pression de contact du plateau tournant proprement dit. A la partie inférieure,ces bras sont munis en extrémité de plots de caoutchouc encastrés et collés formant une sallie face au plateau fixe de la table.These arms are provided on their upper face with non-slip parts in the form of pellets for example to receive the contact pressure of the turntable itself. At the bottom, these arms are fitted at the end with embedded and glued rubber studs forming a projection facing the fixed table top.
Ces butoirs évitent en cas de surcharge accidentelle d'un bras de dépasser la limite d'élasticité de celui-ci et une avarie par déformation permanente. D'autre part ces tampons de caout chouc venant alors frotter sur la table fixe,le plateau mobile ne peut plus tourner, ce qui évite que des enfants n' utilisent le plateau tournant comme jeu en montant dessus.These stops prevent accidental overloading of an arm from exceeding the elastic limit of the latter and damage by permanent deformation. On the other hand these rubber pads then rubbing on the fixed table, the movable plate can no longer rotate, which prevents children from using the turntable as a game when climbing on it.
C'est une sécurité contre un usage qui n'est pas prévu.It is a security against a use which is not intended.
Les joints de caoutchouc épais est souples situés sous la platine et entre la coiffe et la table favorisent par leur écrasement un délignage accidentel de l'arbre en cas de surcharge excentrée du plateau tournant. Ces élasticités co combinées évitent de fausser des pièces du support tournant.The thick, flexible rubber seals located under the plate and between the cover and the table favor, by their crushing, an accidental alignment of the shaft in the event of an eccentric overload of the turntable. These combined elasticities avoid distorting parts of the rotating support.
Si le support tournant est destiné à recevoir un plateau circulaire très lourd en marbre ,granit ou autre, les bras sont soudés sur le moyeu avec un léger angle de l'ordre de IO l'extrémité des bras étant plus haute que le plan horizontal du dessus de moyeu. Sous l'effet de la charge statique du plateau tournant,les bras fléchissent et se mettent dans le mème plan horizontal,assurant une répartition de la pression d'appui . L'ensemble acquiert alors une plus grande rigidité autour de l'axe de rotation. If the rotating support is intended to receive a very heavy circular plate in marble, granite or other, the arms are welded to the hub with a slight angle of the order of 10 the end of the arms being higher than the horizontal plane of the above hub. Under the effect of the static load on the turntable, the arms flex and fall into the same horizontal plane, ensuring a distribution of the support pressure. The assembly then acquires greater rigidity around the axis of rotation.
Si le support tournant est destiné à recevoir un plateau circulaire plus léger,les bras peuvent ètre soudés dans le plan du dessus de moyeu . On interposera des pastilles antidérapantes d'épaisseur variable,plus épaisses vers l'extrémité des bras pour compenser leur légère flexion et pour la raison préceXemment invQgude. If the rotating support is intended to receive a lighter circular plate, the arms can be welded in the plane of the hub top. Interpose non-slip pads of variable thickness, thicker towards the end of the arms to compensate for their slight bending and for the reason previously invQgude.
Le couvercle protégeant les paliers peut être réduit à une simple plaque percée de trois trous si l'épaisseur de la
table permet le logement des paliers plaques La profondeur de ce couvercle variera avec les divers types de tables, et la rigidité recherchée du support tournant. L'écartement des roulements-permet d'avoir un arbre plus long et plus de raideur. L'illustration montre un exemple de roulements très écartés l'un de l'autre alors que la forte épaisseur de la table aurait permis de mettre les roulements cote à cote avec un flasque plat en guise de couvercle et un arbre plus court. Dans le cas présent l'expérience montre que ce montage sur une table de béton de dimensions très particulières donne de meilleurs résultats quant à la stabilité du plateau tournant.The cover protecting the bearings can be reduced to a simple plate pierced with three holes if the thickness of the
table allows housing of plate bearings The depth of this cover will vary with the various types of tables, and the desired rigidity of the rotating support. The spacing of the bearings-allows for a longer shaft and more stiffness. The illustration shows an example of bearings that are very far apart from each other when the high thickness of the table would have made it possible to put the bearings side by side with a flat flange as a cover and a shorter shaft. In the present case, experience shows that this mounting on a concrete table of very specific dimensions gives better results as to the stability of the turntable.
Un dispositif d'étanchéité à lèvre est fixé sur l'arbre sous le moyeu. Cette lèvre frotte sur la surface polie de la platine en acier inoxydable. Ce joint tournant permet de laver la table et son plateau tournant avec un jet d'eu sous pression sans risque d'endommagement des roulements à billes. Cette étanchéité est indispensable dans le cas d'une table de jardin exposée de plus aux intempéries. A lip seal is attached to the shaft under the hub. This lip rubs on the polished surface of the stainless steel stage. This rotating joint allows the table and its turntable to be washed with a pressurized jet of water without risk of damage to the ball bearings. This tightness is essential in the case of a garden table exposed more to the weather.
