The support has a flat base (11) with a peripheral rim (12) projecting vertically downwards to define a space for receiving a runner (15). The support is fixed to the end of the leg by a screw (30) passing through the opening and forced into the end of the leg. The opening is wider than the screw head or the point (3) so as to create a play between the head and the opening wall (140) and allow an angular displacement of the support relative to the foot axis.

Description

La présente invention a pour objet un dispositif de patin adaptable en extrémité de chacun des pieds d'un meuble, notamment d'une chaise en bois plein.The present invention relates to a skid device adaptable at the end of each of the legs of a piece of furniture, in particular of a solid wooden chair.

Il est d'usage courant de garnir les extrémités des pieds d'un meuble, et plus particulièrement ceux d'une chaise, de patins destinés à en faciliter le déplacement sans bruit et sans dommages pour le sol, lorsque ce dernier est un parquet ou un revêtement de sol en matière plastique de type linoléum.It is common practice to garnish the ends of the legs of a piece of furniture, and more particularly those of a chair, with glides intended to facilitate movement without noise and without damage to the floor, when the latter is parquet or linoleum-type plastic flooring.

Les dispositifs connus comprennent généralement un support qui est solidarisable à l'extrémité des pieds d'un meuble, au moyen par exemple d'un clou ou d'une vis, et sur lequel on fixe un patin de feutre dont une des faces est adhésive.Known devices generally include a support which can be joined at the end of the legs of a piece of furniture, for example by means of a nail or a screw, and on which a felt pad is fixed, one of the faces of which is adhesive. .

Toutefois ces dispositifs, une fois solidarisés aux pieds d'un meuble, ne reposent pas toujours à plat sur le sol, du fait de l'inclinaison de certains pieds par rapport audit sol, ce qui peut provoquer le décollement progressif du patin de feutre de son support, le pied ne reposant alors plus que sur ledit support ou sur une de ses arêtes, au risque de rayer le revêtement du sol.However, these devices, once secured to the feet of a piece of furniture, do not always rest flat on the ground, due to the inclination of certain feet relative to said ground, which can cause the felt pad to gradually come off. its support, the foot then resting only on said support or on one of its edges, at the risk of scratching the floor covering.

Pour remédier à cet inconvénient on a proposé des dispositifs utilisant un système de rotule, mais ils sont d'un prix de revient relativement élevé.To overcome this drawback, devices using a ball joint system have been proposed, but they are relatively expensive.

La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de patin d'une conception simple, et donc d'un coût de fabrication peu élevé, qui permet au patin de feutre d'être parfaitement à plat sur le sol, indépendamment de l'inclinaison du pied de meuble.The aim of the present invention is to remedy these drawbacks by proposing a shoe device of a simple design, and therefore of a low manufacturing cost, which allows the felt shoe to be perfectly flat on the ground, regardless of the inclination of the furniture leg.

A cet effet le dispositif de patin objet de la présente invention se caractérise essentiellement en ce qu'il comprend un support en forme de coupelle comportant un fond plat et un rebord périphérique saillant autour dudit fond plat en délimitant un espace destiné à recevoir un patin de feutre ; et en ce que le fond plat est prolongé par une partie pleine sensiblement cônique munie centralement d'un orifice tronconique ou semi-sphérique débouchant au sommet de ladite partie cônique, ledit dispositif étant destiné à être solidarisé à l'extrémité du pied d'un meuble au moyen d'une vis ou d'une pointe à tête fraisée passant à travers ledit orifice et enfoncée dans ladite extrémité du pied de meuble, ledit orifice étant plus évasé que la tête de la vis ou de la pointe de manière à créer un jeu entre ladite tête et ledit orifice, en vue de permettre un déplacement angulaire du support par rapport à l'axe du pied du meuble.To this end, the skate device which is the subject of the present invention is essentially characterized in that it comprises a cup-shaped support comprising a flat bottom and a peripheral rim projecting around said flat bottom delimiting a space intended to receive a skid. felt; and in that the flat bottom is extended by a substantially conical solid part provided centrally with a frustoconical or semi-spherical orifice opening at the top of said conical part, said device being intended to be secured to the end of the foot of a furniture by means of a screw or a point with a countersunk head passing through said orifice and pressed into said end of the furniture leg, said orifice being more flared than the head of the screw or the point so as to create a clearance between said head and said orifice, in order to allow an angular displacement of the support relative to the axis of the base of the piece of furniture.

Le support en forme de coupelle du dispositif selon l'invention est avantageusement réalisé par moulage par injection à partir de matériaux thermoplastiques appropriés.The cup-shaped support of the device according to the invention is advantageously produced by injection molding from suitable thermoplastic materials.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé :

  • la figure 1 représente une vue en coupe selon un plan vertical médian d'un dispositif selon l'invention.
  • la figure 2 représente une vue en coupe selon un plan vertical médian d'un dispositif selon l'invention solidarisé à un pied de meuble en bois plein.
  • la figure 3 représente une vue en coupe selon un plan vertical médian d'un dispositif selon l'invention solidarisé à un autre pied de meuble en bois plein.
In the attached drawing:
  • Figure 1 shows a sectional view along a median vertical plane of a device according to the invention.
  • 2 shows a sectional view along a vertical median plane of a device according to the invention secured to a base of solid wood furniture.
  • 3 shows a sectional view along a median vertical plane of a device according to the invention secured to another base of solid wood furniture.

Si on se réfère à la figure 1 on peut voir que le dispositif selon l'invention comprend un support 1 en forme de coupelle, venant de moulage d'une matière plastique et comportant un fond 11 et un rebord saillant 12 délimitant un espace 120 destiné à recevoir un patin de feutre, non représenté, solidarisé au fond 11 par une face adhésive.If we refer to Figure 1 we can see that the device according to the invention comprises a support 1 in the form of a cup, coming from molding of a plastic material and comprising a bottom 11 and a projecting rim 12 delimiting a space 120 intended to receive a felt pad, not shown, secured to the bottom 11 by an adhesive face.

Le fond 11 est prolongé par une partie 13 cônique et comporte en son centre un orifice 14 troncônique.The bottom 11 is extended by a conical portion 13 and has at its center a frustoconical orifice 14.

Si on se réfère maintenant à la figure 2 on peut voir que le support 1 est solidarisé à l'extrémité 20 d'un pied de meuble 2 au moyen d'une vis 3 traversant sensiblement centralement ledit support 1 par l'orifice 14 troncônique.Referring now to Figure 2 we can see that the support 1 is secured to the end 20 of a furniture leg 2 by means of a screw 3 passing substantially centrally through said support 1 through the frustoconical orifice 14.

Dans l'espace 120 est fixé ,par collage contre le fond 11, un patin de feutre 15 reposant sur le sol 4, le pied de meuble 2 s'appuyant sur le sommet de la partie cônique 13 du support 1, sa face inférieure 20 parallèle au patin 15.In space 120 is fixed, by gluing against the bottom 11, a felt pad 15 resting on the floor 4, the furniture leg 2 resting on the top of the conical part 13 of the support 1, its underside 20 parallel to shoe 15.

Le diamètre de la tige 30 de la vis 3 est légèrement inférieur au diamètre de la plus petite ouverture 140 de l'orifice 14, alors que la tête fraisée 31 de la vis 3 est moins évasée que l'orifice 14 de manière qu'il y ait un certain jeu entre ladite tête 31 et ledit orifice 14.The diameter of the rod 30 of the screw 3 is slightly less than the diameter of the smallest opening 140 of the orifice 14, while the countersunk head 31 of the screw 3 is less flared than the orifice 14 so that it there is a certain clearance between said head 31 and said orifice 14.

On peut voir également que l'angle a formé par le plan contenant la face inférieure 20 du pied 2 et la face externe inclinée 130 de la partie conique 13 est sensiblement égal à l'angle b existant entre la tête 31 de la vis 3 et la paroi interne 140 de l'orifice 14.It can also be seen that the angle a formed by the plane containing the lower face 20 of the leg 2 and the inclined external face 130 of the conical part 13 is substantially equal to the angle b existing between the head 31 of the screw 3 and the internal wall 140 of the orifice 14.

Si on se réfère maintenant à la figure 3 on peut voir que dans le cas d'un pied de meuble 2 incliné par rapport au sol, la vis 3 est enfoncée axialement dans le pied 2 et le patin de feutre 15 repose à plat sur le sol 4, du fait de la conicité de la partie 13 et du jeu possible entre la tête fraisée 31 de la vis 3 et la paroi 140 de l'orifice 14, qui permet au pied 2 d'être incliné sans risque que le patin de feutre 15 se décolle du support 1.If we now refer to Figure 3 we can see that in the case of a furniture leg 2 inclined relative to the ground, the screw 3 is driven axially into the foot 2 and the felt pad 15 rests flat on the floor 4, from made of the taper of the part 13 and of the possible play between the countersunk head 31 of the screw 3 and the wall 140 of the orifice 14, which allows the foot 2 to be inclined without risk of the felt pad 15 coming off support 1.
