Abstract

The seat consists of a rigid base with a flat horizontal section (11) and a curved section (12) with a radius of curvature reducing continuously towards the seat's front edge (10). The seat consists of a rigid base with a flat horizontal section (11) and a curved section (12) with a radius of curvature reducing continuously towards the seat's front edge (10), such that the angle formed between a tangent to the curved surface and the plane of the flat section increases from the flat section to the front edge from 0 to 50 degrees. The seat is covered with a material that is sufficiently firm so as to follow the contour of the seat, and is covered in turn by a thin layer of horse hair and cotton or tapestry.

Description

La présente invention concerne une banquette pour musicien, et en particulier une banquette pour pianiste.The present invention relates to a bench for a musician, and in particular a bench for a pianist.

Les banquettes pour musiciens connues possèdent une assise sensiblement rigide, plane et horizontale, éventuellement recouverte d'un revêtement de mousse très souple pour la rendre plus confortable et d'une tapisserie traditionnelle.The benches for known musicians have a substantially rigid seat, flat and horizontal, possibly covered with a very flexible foam coating to make it more comfortable and a traditional tapestry.

Ce type de banquettes pose un certain nombre de problèmes. En premier lieu, l'angle d'appui idéal du musicien sur la banquette varie suivant la taille, la morphologie, et éventuellement la caractère de la musique jouée ; la banquette connue, du fait de sa forme figée, ne permet pas de satisfaire toutes ces contraintes. Ainsi, le musicien ne peut pas choisir l'angle avec l'horizontale de son appui fessier.This type of bench poses a number of problems. In the first place, the ideal support angle of the musician on the bench varies according to the size, the morphology, and possibly the character of the music played; the known bench, because of its frozen form, does not meet all these constraints. Thus, the musician can not choose the angle with the horizontal of his gluteal support.

Notamment, pour ce qui est de la taille, la hauteur d'un piano ou d'une harpe par exemple étant déterminée, les seuls éléments que l'on peut faire varier sont la hauteur et la position de la banquette ; par conséquent, l'angle entre la verticale et le plan des cuisses du musicien doit varier, de sorte que le point d'appui du musicien sur la banquette n'est pas toujours adéquat.In particular, as regards the size, the height of a piano or a harp for example being determined, the only elements that can be varied are the height and position of the bench; therefore, the angle between the vertical and the plane of the thighs of the musician must vary, so that the point of support of the musician on the seat is not always adequate.

Quant à la morphologie du musicien (proportion tronc/jambes, cambrure lombaire, basculement du bassin, etc...), elle varie d'un individu à l'autre et l'angle d'appui idéal n'est donc pas la même pour tous.As for the morphology of the musician (proportion trunk / legs, lumbar arch, tilting of the pelvis, etc ...), it varies from one individual to another and the ideal angle of support is not the same for everyone.

En outre, après un temps d'assise assez long sur ce type de banquettes, la circulation sanguine peut être affectée par l'effet de barre produit par la pression exercée sur la jambe, et plus précisément sur la cuisse, du musicien par la bordure de la banquette.In addition, after a long sitting time on this type of bench, the blood circulation can be affected by the bar effect produced by the pressure exerted on the leg, and more precisely on the thigh, the musician by the curb from the bench.

On connaît par ailleurs par le document US-4 671 570, une chaise pour musicien selon le préambule de la revendication 1 et ajustable en fonction du type d'instrument joué, destinée plus particulièrement aux musiciens jouant des instruments à vent ou à cordes. L'assise de cette chaise a une forme galbée et est inclinable au moyen de mécanismes à came, l'inclinaison étant opérée par le musicien par action sur un levier.Also known from US-4,671,570, a chair for musician according to the preamble of claim 1 and adjustable depending on the type of instrument played, especially for musicians playing wind instruments or string. The seat of this chair has a curved shape and is reclining by means of cam mechanisms, the inclination being operated by the musician by action on a lever.

Tout comme la banquette décrite plus haut, cette chaise ne permet pas de satisfaire toutes les contraintes de la pratique de la musique, et ne résout pas le problème de la mauvaise circulation sanguine causée par un temps d'assise prolongé sur une telle chaise.Like the bench described above, this chair does not meet all the constraints of the practice of music, and does not solve the problem of poor blood circulation caused by prolonged sitting on such a chair.

La présente invention a donc pour objet de mettre au point une banquette pour musicien adaptée à plusieurs types d'instruments, de taille et de morphologie du musicien ainsi qu'à plusieurs types de morceaux travaillés.The present invention therefore aims to develop a bench for musician adapted to several types of instruments, size and morphology of the musician and several types of pieces worked.

La présente invention a également pour but de mettre au point une telle banquette qui permette d'éviter les nuisances à la circulation sanguine causées par les banquettes de l'art antérieur.The present invention also aims to develop such a bench that avoids the nuisance to blood circulation caused by the benches of the prior art.

La présente invention propose à cet effet une banquette pour musicien comprenant une assise comportant une base rigide, comprenant
une portion plane destinée à être horizontale prolongée par une portion courbée dont le rayon de courbure diminue de manière continue jusqu'au bord de l'assise de sorte que l'angle formé entre la tangente à la surface de la portion courbée et le plan de la portion plane croît depuis la zone de l'assise reliant la portion courbée à la portion plane jusqu'au bord de l'assise, caractérisée en ce que la projection de la dite portion courbée sur le plan de la dite portion plane a une longueur au moins égale à celle de la portion plane.The present invention proposes for this purpose a bench for a musician comprising a seat comprising a rigid base, comprising
a flat portion intended to be horizontal extended by a curved portion whose radius of curvature decreases continuously to the edge of the seat so that the angle formed between the tangent to the surface of the curved portion and the plane of the flat portion increases from the zone of the seat connecting the curved portion to the flat portion to the edge of the seat, characterized in that the projection of said curved portion on the plane of said flat portion has a length at least equal to that of the flat portion.

Grâce à la forme particulière du galbe (portion courbée) de la banquette selon l'invention, le musicien peut choisir sa position sur la banquette en fonction de l'instrument joué, de sa taille, de sa morphologie ou du type de morceau travaillé, et de plus, cette forme particulière nuit nettement moins à la circulation sanguine que les formes de l'art antérieur.Thanks to the particular shape of the curve (curved portion) of the seat according to the invention, the musician can choose his position on the seat according to the instrument played, its size, its morphology or the type of piece worked, and further, this particular form is significantly less harmful to blood circulation than the prior art forms.

Plus précisément, lorsque le musicien est assis sur une banquette de l'art antérieur, il existe un point de compression localisé au niveau de son assise, alors qu'avec la banquette selon l'invention, le point de compression est remplacé par une zone de compression plus étendue. En outre, avec la banquette de l'invention, le point d'appui des ischions (parties de l'os se trouvant en bas et en arrière du bassin) du musicien se trouve dans la zone de compression et non plus à une distance relativement importante de cette dernière. Ceci permet une meilleure répartition du poids du corps sur l'assise, un meilleur équilibre et une meilleure circulation sanguine.More specifically, when the musician sits on a seat of the prior art, there is a point of compression located at its seat, while with the seat according to the invention, the compression point is replaced by a zone more extensive compression. In addition, with the seat of the invention, the point of support of the ischia (parts of the bone located at the bottom and back of the pool) of the musician is in the compression zone and no longer at a relatively large distance from the latter. This allows a better distribution of the weight of the body on the seat, a better balance and a better blood circulation.

De manière très avantageuse, l'angle formé entre la tangente à la surface de la portion courbée et le plan de la portion plane croît de 0° à 50°. Cet intervalle d'angles est optimal pour obtenir l'effet souhaité tout en conservant une assise confortable et favorable à la circulation sanguine.Very advantageously, the angle formed between the tangent to the surface of the curved portion and the plane of the flat portion increases from 0 ° to 50 °. This range of angles is optimal to achieve the desired effect while maintaining a comfortable seat and favorable to blood circulation.

Selon un mode de réalisation de l'invention, le rayon de courbure de la portion courbée décroît depuis la zone de l'assise reliant la portion courbée à la portion plane jusqu'au bord de l'assise.According to one embodiment of the invention, the radius of curvature of the curved portion decreases from the area of the seat connecting the curved portion to the flat portion to the edge of the seat.

Selon une caractéristique avantageuse, l'assise est recouverte d'un revêtement en matériau suffisamment ferme pour suivre le contour de l'assise. Le revêtement est par exemple en un matériau à base de polyétheruréthane cellulaire de dureté voisine de celle du SYLOMER R25.According to an advantageous characteristic, the seat is covered with a material coating sufficiently firm to follow the contour of the seat. The coating is for example a material based on cellular polyetherurethane of hardness close to that of SYLOMER R25.

Selon une autre caractéristique avantageuse de l'invention.According to another advantageous characteristic of the invention.

D'autres caractéristiques et avantages de la présente invention apparaîtront dans la description suivante d'un mode de réalisation de l'invention, donné à titre illustratif et nullement limitatif.Other features and advantages of the present invention will appear in the following description of an embodiment of the invention, given by way of illustration and in no way limiting.

La figure unique représente en perspective l'assise d'une banquette pour musicien selon l'invention.The single figure shows in perspective the seat of a bench for a musician according to the invention.

On voit sur cette figure l'assise 10 d'une banquette pour musicien selon l'invention. La zone supérieure de cette assise, c'est-à-dire celle sur laquelle le musicien s'assoit, comporte à sa partie arrière une portion plane 11 prolongée par une portion courbée 12. Pour la clarté du dessin, la séparation entre les deux portions a été représentée par un trait mixte ; on comprendra néanmoins qu'en pratique, les deux portions 11 et 12 sont dans la prolongation l'une de l'autre sans séparation.This figure shows the seat 10 of a bench for a musician according to the invention. The upper zone of this seat, that is to say the one on which the musician sits, comprises at its rear part a flat portion 11 extended by a curved portion 12. For clarity of the drawing, the separation between the two portions was represented by a dashed line; we will understand nevertheless that in practice, the two portions 11 and 12 are in the extension of one another without separation.

La portion courbée 12 se trouve à l'avant de la banquette, et la portion plane 11 à l'arrière. On appelle avant de la banquette la partie de cette dernière se trouvant à l'avant lorsqu'un musicien y est assis.The curved portion 12 is at the front of the seat, and the flat portion 11 at the rear. The front part of the seat is called before the seat when a musician sits there.

Plus précisément, la portion plane 11, destinée à être horizontale, est délimitée à sa partie supérieure par le segment AB de longueur environ égale à 16,5 cm.More specifically, the flat portion 11, intended to be horizontal, is delimited at its upper part by the segment AB of length approximately equal to 16.5 cm.

La portion courbée 12 a un rayon de courbure qui diminue depuis l'arrière de l'assise 10 jusqu'à l'avant de cette dernière. Elle est schématiquement subdivisée à sa partie supérieure en plusieurs arcs BC, CD, DE, EF et FG. Le rayon de courbure de ces différents arcs diminue depuis l'arrière de l'assise 10 jusqu'à l'avant de cette dernière.The curved portion 12 has a radius of curvature that decreases from the back of the seat 10 to the front thereof. It is schematically subdivided at its upper part into several arcs BC, CD, DE, EF and FG. The radius of curvature of these different arches decreases from the back of the seat 10 to the front of the latter.

Dans l'exemple illustré sur la figure, les rayons de courbures des différents arcs sont ainsi les suivants :

  • RBC = 56 cm
  • RCD = 39 cm
  • RDE = 21 cm
  • REF = 11 cm
  • RFG = 3,5 cm
In the example illustrated in the figure, the radii of curvature of the different arcs are thus as follows:
  • R BC = 56 cm
  • R CD = 39 cm
  • R DE = 21 cm
  • R EF = 11 cm
  • R FG = 3.5 cm

En outre, l'angle entre la tangente aux points B, C, D, E et F et le plan de la portion plane 11 augmente depuis le point B jusqu'au point F. Il vaut ainsi successivement 0°, 10°, 20°, 30° et 48° respectivement aux points B, C, D, E et F.In addition, the angle between the tangent at the points B, C, D, E and F and the plane of the planar portion 11 increases from the point B to the point F. It is thus successively 0 °, 10 °, 20 °, 30 ° and 48 ° respectively at points B, C, D, E and F.

La longueur de la projection de la portion courbée 12 sur le plan de la portion plane 11 est d'environ 23,5 cm.The length of the projection of the curved portion 12 on the plane of the flat portion 11 is about 23.5 cm.

Enfin, la hauteur de l'assise 10 au niveau de la portion plane 10 est d'environ 9 cm.Finally, the height of the seat 10 at the flat portion 10 is about 9 cm.

L'assise 10 peut être fabriquée en tout matériau suffisamment rigide, comme par exemple du bois. Elle est recouverte au niveau de sa zone supérieure d'un revêtement (non représenté) constitué d'un matériau suffisamment ferme pour suivre de très près le contour de l'assise 10. Ce matériau peut être notamment un polyétheruréthane cellulaire de dureté comparable à celle du SYLOMER R25 d'épaisseur 25 mm. Ce matériau est recouvert d'une mince couche de crin ou de coton, elle-même recouverte d'une toile, puis d'une tapisserie au choix.The seat 10 can be made of any sufficiently rigid material, such as wood. It is covered in its area upper of a coating (not shown) consisting of a sufficiently firm material to follow very closely the contour of the seat 10. This material may be in particular a cellular polyetherurethane hardness comparable to that of SYLOMER R25 25 mm thick . This material is covered with a thin layer of horsehair or cotton, itself covered with a cloth, then a tapestry of your choice.

La banquette selon l'invention peut être utilisée par tout type de musicien. Elle est tout particulièrement adaptée aux pianistes.The bench according to the invention can be used by any type of musician. It is particularly suitable for pianists.

La figure unique montre seulement l'assise d'une banquette pour musicien selon l'invention, mais il est bien évident que cette assise munie d'une structure porteuse adaptée (quatre pieds par exemple) forme la banquette selon l'invention.The single figure shows only the seat of a bench for musician according to the invention, but it is obvious that this seat provided with a suitable supporting structure (four feet for example) forms the seat according to the invention.

Bien entendu, la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit.Of course, the present invention is not limited to the embodiment which has just been described.

Notamment, les dimensions données ci-dessus l'ont été à titre d'exemple et l'on pourra choisir d'autres dimensions du moment que la caractéristique principale de l'invention, à savoir la courbure de la portion courbée, est respectée.In particular, the dimensions given above have been given by way of example and other dimensions can be chosen from the moment that the main characteristic of the invention, namely the curvature of the curved portion, is respected.

Par ailleurs, on pourra employer pour fabriquer l'assise de la banquette selon l'invention tout matériau adapté.Furthermore, it can be used to manufacture the seat of the seat according to the invention any suitable material.

Enfin, on pourra remplacer tout moyen par un moyen équivalent sans sortir du cadre de la présente invention, définie par les revendications.Finally, any means can be replaced by equivalent means without departing from the scope of the present invention, defined by the claims.
