Abstract

The method involves locally applying a protective layer (2) on an upper (1) of an ice skating boot by scrapping the leather in an area to be protected and applying a polyurethane adhesive on the scraped surface to locally apply the layer, where the protective layer is formed of a micro-injected polyurethane synthetic material. The protective layer is injected by a mold part equipped with several blowholes, where the mold part is applied with pressure on the leather. An independent claim is also included for a boot equipped with a protection layer obtained by an ice skating boot protection method.

Description

       

  [0001] L'invention a pour objet un procédé de protection d'une bottine de patin à glace, à tige en cuir, particulièrement pour le patinage en couple et pour la danse.

[0002] Aussi bien en patinage de compétition en couple qu'en danse, les bottines des patineurs, particulièrement le côté intérieur du pied, sont exposées à recevoir des coups de lame abîmant le cuir et pouvant aller jusqu'à couper l'épaisseur du cuir. Il serait possible de protéger la bottine en cousant ou collant un morceau de cuir.

   Ceci aurait pour effet toutefois d'augmenter sensiblement l'épaisseur de la bottine et de créer une protubérance inesthétique inadmissible.

[0003] L'invention a pour but d'obtenir une protection efficace de la bottine sans affecter sensiblement l'aspect esthétique de la bottine.

[0004] A cet effet, le procédé selon l'invention est caractérisé en ce qu'on applique localement sur la tige au moins du côté intérieur du pied, une couche protectrice en matière synthétique par injection. L'injection sera, de préférence, une micro-injection.

[0005] La micro-injection est une injection répartie sur une multitude de points de faible diamètre.

   Ceci permet d'obtenir un très bon ancrage en une multitude de points d'une mince couche de matière synthétique.

[0006] De préférence, afin d'obtenir une très bonne adhérence, on gratte préalablement la surface du cuir destinée à recevoir la matière synthétique, de préférence du polyuréthane, puis on enduit la surface grattée de colle avant de procéder à la micro-injection. La colle est, de préférence, une colle polyuréthane réactivable.

[0007] La protection obtenue présente une épaisseur inférieure ou égale à 1 mm.

[0008] L'invention a également pour objet une bottine de patin à glace équipée d'une telle protection.

[0009] Le dessin annexé représente, à titre d'exemple, une bottine obtenue par le procédé selon l'invention.

[0010] L'unique figure du dessin représente une bottine de patinage sur glace comprenant une tige en cuir 1.

   Le côté intérieur de la bottine est muni, dans la zone exposée aux coups de lame, d'une couche de matière synthétique 2, en l'occurrence du polyuréthane, fixée au cuir par micro-injection. Le côté extérieur de la bottine pourrait, bien entendu, être également muni d'une telle couche de protection.

[0011] La protection est appliquée sur le cuir à plat, avant le montage de la tige de la bottine. La surface du cuir à revêtir est préalablement grattée, puis enduite de colle polyuréthane réactivable. Puis on procède, toujours à plat, à la micro-injection de la couche protectrice. Pour ce faire, on applique par pression, dans le but d'assurer l'étanchéité, un demi-moule sur le cuir, demi-moule dont la face supérieure présente une multitude de trous d'injection pour la matière thermoplastique ramollie par chauffage.

   La couche protectrice est, de préférence, colorée dans la masse, de la même couleur que le cuir.

[0012] En variante, il est possible d'appliquer la couche protectrice sur une tige déjà mise en forme, mais cette méthode est plus coûteuse car elle exige des moules plus compliqués.

[0013] D'autres matières synthétiques que le polyuréthane pourraient, bien entendu, être utilisées.

[0014] En variante, la protection 2 pourrait être fabriquée séparément par moulage dans un moule approprié, puis fixée par collage sur le cuir.



  The invention relates to a method of protecting an ice skating boot with leather upper, particularly for pair skating and for dancing.

[0002] In both pairs and dance competition skating, the boots of skaters, particularly the inner side of the foot, are exposed to receiving blows of blade damaging the leather and up to cutting the thickness of the skate. leather. It would be possible to protect the boot by sewing or gluing a piece of leather.

   This would, however, have the effect of substantially increasing the thickness of the boot and create an unsightly unaesthetic protrusion.

The invention aims to obtain effective protection of the boot without significantly affecting the aesthetic appearance of the boot.

For this purpose, the method according to the invention is characterized in that locally applied on the rod at least on the inner side of the foot, a protective layer of synthetic material by injection. The injection will preferably be a microinjection.

Microinjection is an injection distributed over a multitude of small diameter points.

   This provides a very good anchoring in a multitude of points of a thin layer of synthetic material.

Preferably, in order to obtain a very good adhesion, the surface of the leather intended to receive the synthetic material, preferably polyurethane, is first scraped, then the scraped surface is coated with glue before proceeding with the microinjection. . The glue is preferably a reactive polyurethane glue.

The protection obtained has a thickness less than or equal to 1 mm.

The invention also relates to an ice skating boot equipped with such a protection.

The accompanying drawing shows, for example, an ankle obtained by the method according to the invention.

The sole figure of the drawing shows an ice skating boot comprising a leather upper 1.

   The inner side of the boot is provided in the area exposed to blows of a layer of synthetic material 2, in this case polyurethane, attached to the leather by micro-injection. The outer side of the boot could, of course, also be provided with such a protective layer.

The protection is applied to the leather flat, before mounting the stem of the boot. The surface of the leather to be coated is scraped beforehand, then coated with reactive polyurethane glue. Then one proceeds, always flat, the micro-injection of the protective layer. To do this, is applied by pressure, for the purpose of sealing, a half-mold on the leather half-mold whose upper face has a multitude of injection holes for the thermoplastic softened by heating.

   The protective layer is preferably colored in the mass, the same color as the leather.

Alternatively, it is possible to apply the protective layer on a rod already shaped, but this method is more expensive because it requires more complicated molds.

Other synthetic materials than polyurethane could, of course, be used.

Alternatively, the protection 2 could be manufactured separately by molding in a suitable mold, and then fixed by gluing on the leather.
