Abstract

Suivant l'invention on part d'un bloc en bois (1) qui est usiné pour présenter le contour désiré pour les semelles, on creuse sur l'une au moins de ses faces une série d'entailles transversales (5, 6) qui sont ensuite remplies d'une couche de caoutchouc souple, et on taille longitudinalement ledit bloc au niveau du fond des entailles.According to the invention, we start from a wooden block (1) which is machined to present the desired contour for the soles, we hollow out on one at least of its faces a series of transverse notches (5, 6) which are then filled with a layer of flexible rubber, and said block is cut longitudinally at the bottom of the notches.

Description

La présente invention a trait aux semelles intérieures en bois de forme anatomique qui de par leur flexibilité sont particulièrement aptes à être utilisés dans des ambiances humides ou même dans l'eau.The present invention relates to wooden insoles of anatomical shape which due to their flexibility are particularly suitable for use in humid environments or even in water.

On sait qu'on utilise de plus en plus des sabots ou autres chaussures comprenant une enveloppe en matière synthétique formant boîtier pour une semelle interne en bois flexible ou simi-rigide, laquelle semelle offre au pied un appui en une matière naturelle propre à absorber et/ou à favoriser la sudation tout en autorisant l'immersion dans de l'eau et en comportant un degré de flexibilité suffisant pour ne pas gêner la libre articulation du pied lors de la marche.It is known that more and more hooves or other shoes are used comprising a plastic envelope forming a housing for a flexible or simi-rigid wooden insole, which sole provides the foot with support in a natural material capable of absorbing and / or to promote sweating while allowing immersion in water and having a sufficient degree of flexibility so as not to hinder the free articulation of the foot during walking.

Les semelles de ce type connues à l'heure actuelle sont réalisées en collant sur un support souple en matière synthétique des feuilles de bois qui peuvent présenter soit une épaisseur très réduite pour que l'ensemble reste flexible, soit une épaisseur plus accentuée, auquel cas il y a lieu, pour obtenir la flexibilité requise, de prévoir des cavités transversales.The soles of this type known at the present time are produced by gluing on a flexible support of synthetic material sheets of wood which may have either a very reduced thickness so that the assembly remains flexible, or a more accentuated thickness, in which case to obtain the required flexibility, provision should be made for transverse cavities.

On comprend aisément que la durée d'utilisation des semelles en feuilles très minces est réduite, tandis que celles à cavités transversales comportent un prix de fabrication plus élevé tout en provoquant un désagrément engendré par les pinçages de la peau ou des bas dus aux déplacements desdites cavités lors de la marche. On notera en outre que les semelles de l'un et l'autre type ne peuvent présenter qu'un profil plan.It is easy to understand that the duration of use of very thin sheet soles is reduced, while those with transverse cavities have a higher manufacturing price while causing an inconvenience caused by pinching of the skin or stockings due to the movements of said cavities when walking. It will also be noted that the soles of either type can only have a flat profile.

C'est à ces inconvénients qu'entend principalement remédier l'invention, laquelle a pour objets d'une part le procédé de réalisation de semelles intérieures flexibles défini dans la revendication 1, d'autre part les semelles obtenues par mise en oeuvre dudit procédé.It is to these drawbacks that the invention mainly intends to remedy, which has for its objects on the one hand the method of producing flexible insoles defined in claim 1, on the other hand the soles obtained by implementing said method .

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 à 5 illustrent schématiquement en perspective les différentes phases du procédé de réalisation suivant l'invention.
  • Fig. 6 montre de la même manière la semelle obtenue.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages it is likely to provide:
  • Fig. 1 to 5 schematically illustrate in perspective the different phases of the production method according to the invention.
  • Fig. 6 shows in the same way the sole obtained.

Conformément à l'invention, on commence par réaliser un bloc de bois 1 (fig. 1) présentant les dimensions et les caractéristiques compatibles avec les semelles à obtenir, étant observé que les faces latérales 2 dudit bloc sont déjà conformées en fonction du profil désiré pour celles-ci.According to the invention, we begin by making a block of wood 1 (fig. 1) having the dimensions and characteristics compatible with the soles to be obtained, it being observed that the lateral faces 2 of said block are already shaped according to the desired profile for these.

Ce bloc 1 est ensuite usiné latéralement de façon à lui conférer le profil voulu pour les semelles au niveau du contour de celles-ci et de leurs surfaces. Comme montré en fig. 2 on fait simultanément apparaître aux extrémités de ce bloc 1 deux bossages 3 et 4 qui sont destinés à permettre la préhension dudit bloc sur la machine spéciale de tournage et de profilage qui est utilisée pour le travail.This block 1 is then machined laterally so as to give it the desired profile for the soles at the level of the outline thereof and their surfaces. As shown in fig. 2 simultaneously reveals at the ends of this block 1 two bosses 3 and 4 which are intended to allow the gripping of said block on the special turning and profiling machine which is used for work.

Ensuite et comme montré en fig. 3, on réalise, sur chacune des deux surfaces opposées du bloc 1, une série d'entailles transversales 5, respectivement 6, orientées parallèlement les unes aux autres. On remarquera que les entailles de chaque série s'étendent, à partir de la surface envisagée, jusqu'à une courte distance de la zone médiane du bloc 1, de façon à ménager entre le fond des entailles 5 et 6 des deux séries une épaisseur suffisante pour conserver audit bloc sa rigidité.Then and as shown in fig. 3, a series of transverse notches 5, respectively 6, oriented parallel to each other, is produced on each of the two opposite surfaces of the block 1. It will be noted that the notches of each series extend, from the envisaged surface, up to a short distance from the median zone of block 1, so as to provide between the bottom of the notches 5 and 6 of the two series a thickness sufficient to maintain the rigidity of said block.

Ceci fait, on fait pénétrer à froid dans les entailles 5 et 6 une couche de caoutchouc 7 (fig. 5), à la suite de quoi une opération de fraisage exécutée à l'aide d'une machine appropriée permet d'éliminer la partie de ladite couche de caoutchouc qui recouvre la surface en bois, en ne laissant substister du caoutchouc qu'à l'intérieur des entailles susmentionnées, comme illustré en fig. 5.This done, a layer of rubber 7 (fig. 5) is made to cold penetrate into the notches 5 and 6, after which a milling operation carried out using an appropriate machine makes it possible to eliminate the part of said layer of rubber which covers the wooden surface, allowing rubber to remain only inside the notches above, as illustrated in fig. 5.

A ce moment on effectue une taille longitudinale du bloc 1 le long des lignes représentées en tracé interrompu en 8 et 9, ces lignes étant positionnées de manière à ce que la coupe intéresse toute la couche de bois disposée au delà du fond des entailles 5, respectivement 6. Ce processus est mené de façon à éliminer simultanément les deux bossages d'extrémité 3 et 4 du bloc 1, de telle sorte qu'on obtient finalement deux semelles opposées parfaitement symétriques, identiques à celle qui a été représentée à l'état isolé en 10 en fig. 6.At this time, a longitudinal size of the block 1 is carried out along the lines shown in broken lines at 8 and 9, these lines being positioned so that the cut affects the entire layer of wood disposed beyond the bottom of the notches 5, respectively 6. This process is carried out so as to simultaneously eliminate the two end bosses 3 and 4 from block 1, so that ultimately two perfectly symmetrical opposite flanges are obtained, identical to that which has been shown in the state isolated in 10 in fig. 6.

Les semelles en bois ainsi réalisées sont susceptibles, de par leur symétrie, de convenir pour les deux sabots d'une paire destinée à la même personne. Leur corps en bois présente un profil anatomique qui est profilé de manière précise sur leur face supérieure qui vient au contact du pied de l'usager, tandis que leur face inférieure, destinée à prendre appui contre la chaussure elle-même, est plane.The wooden soles thus produced are likely, by their symmetry, to be suitable for the two hooves of a pair intended for the same person. Their wooden body has an anatomical profile which is precisely profiled on their upper face which comes into contact with the foot of the user, while their lower face, intended to bear against the shoe itself, is flat.

La face supérieure.de chaque semelle 10 présente une série de bandes parallèles 11 disposées entre les couches de caoutchouc 12 qui correspondant aux cavités 5 ou 6 et qui assurent la liaison entre lesdites bandes en assurant la tenue de l'ensemble tout en conférant à celui-ci une flexibilité suffisante pour ne pas gêner l'articulation du pied au cours de la marche. Les couches 12 de caoutchouc évitent tout glissement intempestif du pied en même temps qu'elles s'opposent à tout déplacement intempestif de la semelle à l'intérieur du sabot ou autre chaussure. Les dimensions de la semelle sont parfaitement stables par suite de la déformabilité élastique des couches 12 sus-indiquées.The upper face of each sole 10 has a series of parallel strips 11 disposed between the layers of rubber 12 which correspond to the cavities 5 or 6 and which provide the connection between said strips while ensuring the holding of the assembly while giving that sufficient flexibility so as not to hinder the articulation of the foot during walking. The layers 12 of rubber prevent any untimely sliding of the foot at the same time as they oppose any untimely movement of the sole inside the shoe or other shoe. The dimensions of the sole are perfectly stable as a result of the elastic deformability of the layers 12 mentioned above.

Il va de soi qu'en dépit des avantages présentés, sur le plan du prix de revient notamment, par la réalisation simultanée de deux semelles à partir d'un même bloc de bois, telle qu'exposée ci-dessus et illustrée sur le dessin, l'invention est susceptible d'être mise en oeuvre pour l'obtention d'une semelle unique à partir d'un même bloc. En pareil das face inférieure de ce bloc n'est pas usinée et est prévue plane dès l'origine.It goes without saying that despite the advantages presented, particularly in terms of cost price, by the simultaneous production of two soles from the same block of wood, as set out above and illustrated in the drawing. , the invention is capable of being implemented for obtaining a single sole from a single block. In such a case, the underside of this block is not machined and is provided flat from the outset.
