Abstract
Description
"Disposttif pour l'injection d'articles chaussants notan- ment de mOles et articles ainsi obtenus",
L'invention concerne un dispos-itif d'inw
jection pour la fabrication d'articles chaussants notamment de mûles,à bout ouvert ou non, desttnes en priorite
aux professionnels exercant une activite debout tels qu'infirmiers, infirm1eres, coiffeurs, enseignants,etc..."Device for injecting footwear, in particular molds and articles thus obtained",
The invention relates to an information device.
jection for the manufacture of footwear including blackberries, open toe or not, desttnes in priority
to professionals exercising a standing activity such as nurses, hairdressers, teachers, etc ...
La station debout provoque,(les phlébolo-
gues et les pédologues en conviennent), de graves pertur--
Bations physiologiques et morphologiques qui ont dues, le plus souvent, au- chaussant. des chaussures et a la fatigue. C'est pour cette raison que l'on a vu apparattre il y a plusieurs années des articles chassants com- portant des semelles dont la surface, en contact avec le pied, a été façonnée ou usinée pour épouser le plus étroitement possible la morphologie du pied, c'est-à- dire la convexite des orteils et la concavité de la voûte plantaire.Ces semelles sont le plus souvent réalisées en bois et doivent etre usines ou gravées une a une, ce qui, bien entendu, alourdit les courts de fabrication.The standing position causes, (the phlebolo-
gues and soil scientists agree), serious disruption--
Physiological and morphological bations which have, more often than not, caused over-sleep. shoes and fatigue. It is for this reason that we saw appear several years ago hunting articles comprising soles whose surface, in contact with the foot, was shaped or machined to marry as closely as possible the morphology of the foot, that is to say the convexity of the toes and the concavity of the arch of the foot. These soles are most often made of wood and must be planted or engraved one by one, which, of course, increases the short manufacturing.
L'invention a pour but de realiser en série et par inJection des articles chaussants presen- tant une configuration adaptée a la morphologie du pied tout en permettant par l'automatisation du procédé de reduire très sensiblement le prix de revient de l'article. The object of the invention is to produce, in series and by injection, footwear having a configuration adapted to the morphology of the foot while allowing, by the automation of the process, to reduce the cost price of the article very appreciably.
Pour ce faire le dispositif d'injection qui est constitue de façon usuelle d'une forme metallique et d'un pave de semelle,pourvu d'une cavité de mou-lage, est caractérisé en ce que la base de la forme est usinée et presente une configuration compatible avec la morphologie du pied. Ainsi lors de l'injection de la semelle dans la cavité de moulage la matière sous pres sion épousera pleinement la configuration de la forme et par suite de gazonner a cette configuration la première de montage affichée sur la forme,avant l'injec- tion de la semelle. To do this, the injection device, which usually consists of a metallic form and a sole pave, provided with a molding cavity, is characterized in that the base of the form is machined and has a configuration compatible with the morphology of the foot. Thus, during the injection of the sole into the molding cavity, the material under pressure will fully conform to the configuration of the form and, consequently, to pitch in this configuration the first mounting displayed on the form, before the injection of the sole.

Le but essentiel de l'invention réside
dans un nouveau procede de fabrication d'articles chaus
sants notamment de mules dont la face supérieure de la
semelle presente une configuration coïncidant avec la morphologie du pied afin d'assurer le meilleur confort
à l'utilisateur.The essential object of the invention lies
in a new process for manufacturing articles
including mules whose upper side of the
sole has a configuration coinciding with the morphology of the foot to ensure the best comfort
to the user.
Conformément à l'invention la base et no-
tamment la face inférieure 11 de la forme metalltque 1
est usinée, de préférence gravee, pour présenter, au niveau du bout, de legers bossages en relief préfigurant
la position des orteils du pied, ces bossages etant le
négatif des cavités qu'ils permettront d'obtenir dans
la face superieure de la semelle injectée. La base de
la forme comporte encore une concavité 12, au niveau de
la cambrure, préfigurant la voûte plantaire. Ainsi cette
forme est façonnée pour presenter une configuration pro
che du negatif de la morphologie du pied de maniere à ce
que la semelle qui sera obtenue a l'aide de cette forme
presente les cavités d'orteils et le bossage de soutien
de la volte plantaire.According to the invention the base and no-
especially the underside 11 of the metal shape 1
is machined, preferably engraved, to present, at the end, slight bosses in relief foreshadowing
the position of the toes of the foot, these bosses being the
negative cavities they will get in
the upper face of the injected sole. The base of
the shape also has a concavity 12, at the level of
the arch, foreshadowing the arch of the foot. So this
shape is shaped to present a professional configuration
che of the negative of the morphology of the foot so that
that the sole that will be obtained using this shape
has toe cavities and support boss
of the plantar.
Sur la forme ainsi usinée on affiche l'em- peigne 2 après l'avoir préalablement assemblée à une première de montage 3 a l'aide d'une piqDre se situant de préférence en retrait de la carre de forme,c'est- -dire sous la forme,de manière a ce que celle-ci soit noyee dans la matière injectée. On the shape thus machined, the symbol 2 is displayed after having previously assembled it to a first assembly 3 using a pin preferably located behind the shaped edge, that is - say in the form, so that it is embedded in the injected material.
Etant donne que la tige ne comporte pas de quartiers ni d'embottage, on assure sa stabilisation sur la forme métallique par une talonnette 5,débordant de la première de montage 3,et qui permet de positionner la tige par une simple pointe 6. Wien entendu, cette lan- guette sera arasée au contour de la semelle après injection. Since the rod does not have any quarters or embedding, it is stabilized on the metallic form by a heel-piece 5, projecting from the first mounting 3, and which makes it possible to position the rod by a simple point 6. Wien of course, this tongue will be leveled off around the sole of the sole after injection.
Le pave de semelle 7 est pourvu d'une cavité de moulage 8 correspondant au volume et au profil de la semelle. On peut, s nécessaire, introduire dans cette cavité, préalablement a l'inJection, un talon compense g (figure 3) permettant d'économiser de la matière et d'alleger l'article.Dans ce cas le talon est isolé du fond de la cavité de moulage par un ou plusieurs tétons 10 laissant subsis-ter, autour du talon, un passage periphe rique destiné son enrobage,
Lorsque la forme est équipée de l'emplie gne et de la première de montage (montage bonnet) on ame- ne la forme au-dessus de la cavité de moulage puis on injecte dans cette cavité, par la voie d'un ou plusieurs canneaux d'injection 11, reliés a une tête d'extrusion, la matière destinée a constituer la semelle. La pression d'injection est suffisante pour deformer la première de montage 3 afin de lui faire épouser la confit guration de la forme telle qu'elle a eté ci-dessus décrite.Ainsi la face de la semelle en contact avec le pied presentera, après moulage, la configuration inverse de la base de la forme.The sole pave 7 is provided with a molding cavity 8 corresponding to the volume and the profile of the sole. It is possible, if necessary, to introduce into this cavity, prior to injection, a compensating heel g (FIG. 3) making it possible to save material and to lighten the article. In this case the heel is isolated from the bottom of the molding cavity by one or more pins 10 leaving a periphic passage intended for its coating around the heel,
When the shape is equipped with the filled mold and the first mounting (cup mounting), the shape is brought above the molding cavity and then injected into this cavity, by means of one or more channels injection 11, connected to an extrusion head, the material intended to constitute the sole. The injection pressure is sufficient to deform the first mounting 3 in order to make it conform to the confit guration of the shape as it was described above. Thus the face of the sole in contact with the foot will present, after molding, the reverse configuration of the base of the form.
On peut utiliser, pour l'injection de la semelle,du P,VC. expansé ou encore des matières plaste ques anti-statiques et stérilisables connues du commerce,La première de montage est réalisée en matière synthetique, notamment en P.V.C, expansé ou encore en tissu synthéti- que et pur coton de type eponge a bouclettes. P, VC can be used for the injection of the sole. expanded or still plast ques anti-static and sterilizable materials known from the trade, The first assembly is made of synthetic material, in particular of P.V.C, expanded or also of synthetic fabric and pure cotton of the terry type with loops.
Avantageusement, la première de montage peut comporter sur sa face extérieure, en contact avec le pied, des saillies tels que des picots assurant un massage de la face inférieure du pied favorisant la ciro culation du sang. Advantageously, the first mounting may include on its outer face, in contact with the foot, projections such as spikes ensuring a massage of the underside of the foot promoting ciro culation of blood.
Une mûle réalisée à partir du dispositif d'injection selon l'invention est illustrée en figure 4 où l'on observe effectivement que la talonnette de positionnement de l'empeigne 5 a été arasée. Ben entendu, l'empeigne peut être ouverte ou fermee a son estrémi:te c'est-a-dire au niveau des orteils. A mulberry produced from the injection device according to the invention is illustrated in FIG. 4 where it is effectively observed that the heel for positioning the upper 5 has been leveled. Of course, the upper can be opened or closed at its hem: you ie at the toes.
Le matériel ciodessus décrit permet d'ace crottre considérablement le confort des articles ciaus- sants et, surtout, de réduire dans des porportions notables les courts de fabrication de manière admettre a la disposition des professionnels des articles chaussants notamment des mUles évitant la fatigue et les lésions dues aux stations prolongées debout. The material described above makes it possible to considerably increase the comfort of waxing articles and, above all, to reduce manufacturing shortages in notable portions so as to allow footwear to be made available to professionals, in particular males avoiding fatigue and lesions due to prolonged standing.
Bien entendu, il faut disposer d'autant de formes qu'il y a de pointures dans une gamme d'articles chaussants donnée. Of course, there must be as many shapes as there are sizes in a given range of footwear.
