Abstract

The skate consists of a frame with a lower lengthwise member carrying the rollers (3) and an upper plate to which the boot is attached. It also has a ventilation channel beneath the boot, with air entering through an intake (11a) at its forward end and passing into the boot through apertures (12) in the sole. The ventilation channel is made from a plastics material by blow extrusion, and is divided into sections by one or more lengthwise ribs. It has inner deflectors to guide the air flow towards the apertures.

Description

La présente invention concerne un patin du type à roues, et notamment à roues en ligne, comprenant d'une part un châssis dont une partie inférieure longitudinale porte lesdites roues et d'autre part une chaussure formée par une tige surmontant une semelle destinée à être fixée sur une platine supérieure du châssis, le volume de ladite tige et/ou semelle étant en communication avec l'extérieur de façon à obtenir sa ventilation interne par amenée d'air.The present invention relates to a skate of the wheel type, and in particular to in-line wheels, comprising on the one hand a chassis of which a lower longitudinal part carries said wheels and on the other hand a shoe formed by a rod surmounting a sole intended to be fixed on an upper plate of the chassis, the volume of said rod and / or sole being in communication with the outside so as to obtain its internal ventilation by air intake.

Ce type de patin est destiné à l'entraínement des patineurs sur glace hors patinoire, mais également à tous sportifs désireux d'entretenir ou de perfectionner sur un sol dur goudronné, cimenté, etc. les techniques utilisées dans des sports de glisse tels que le ski de piste, le ski de fond, le patin à glace, etc.This type of skate is intended for the training of ice skaters outside the rink, but also to all athletes wishing to maintain or improve on hard paved soil, cemented, etc. techniques used in board sports such as downhill skiing, cross-country skiing background, ice skating, etc.

C'est ainsi que la pratique de ce sport comprend une phase motrice ou propulsive en faisant diverger le patin vers l'extérieur et en prenant un appui latéral sur les roues ainsi inclinées, à la manière d'une prise de carre, puis une phase de glisse s'effectuant en repositionnant les roues perpendiculairement par rapport au sol.This is how the practice of this sport includes a motor or propulsive phase in causing the skid to diverge outwards and taking lateral support on the wheels as well inclined, like an edge grip, then a sliding phase taking place repositioning the wheels perpendicular to the ground.

Une chaussure de ce type est connue par le brevet US N° 5 171 033. Celui-ci décrit une chaussure présentant la particularité d'être réalisée à partir d'une coque rigide comportant une pluralité d'ouvertures, de ventilation débouchant dans le volume interne de la coque. Un chausson est disposé librement dans cette coque afin que les mouvements du pied provoquent une ventilation interne par coopération entre une action de pompage fournie par le mouvement du chausson à l'intérieur de la coque et lesdites ouvertures de la coque.A shoe of this type is known from US Patent No. 5,171,033. This describes a shoe having the particularity of being made from a rigid shell comprising a plurality of openings, ventilation opening into the internal volume of the hull. A liner is freely placed in this shell so that the movements of the foot cause internal ventilation by cooperation between a pumping action provided by the movement of the liner inside the shell and said openings of the shell.

Si un tel concept est susceptible de favoriser l'aération du pied, en revanche il conserve à la chaussure toute sa rigidité, car la coque, même si elle reçoit un chausson souple, constitue une structure enveloppante ferme du pied.If such a concept is likely to promote ventilation of the foot, however it keeps the shoe in all its rigidity, because the shell, even if it receives a flexible liner, constitutes a firm enveloping structure of the foot.

Par ailleurs, l'efficacité de l'action de pompage exercée par le chausson est assez douteuse du fait que dans une chaussure de ce type on cherche justement à éviter tout mouvement relatif du pied générateur d'inconfort (frottement, ampoule) et de manque de précision.In addition, the effectiveness of the pumping action exerted by the liner is quite doubtful that in a shoe of this type one seeks precisely to avoid all relative movement of the foot generating discomfort (friction, blister) and lack of precision.

On recherche également dans un tel produit une structure de chaussure souple et légère assurant une bonne tenue du pied, un confort d'utilisation, et une moindre fatigue.We also look in such a product for a flexible and light shoe structure ensuring good foot hold, comfort of use, and less fatigue.

Le brevet américain n° 5 401 039 enseigne de ventiler le volume interne de la coque en amenant de l'air capté à l'extérieur par des trous ménagés sur le plan inférieur de la semelle et cela par l'intermédiaire d'un conduit à l'extrémité duquel se trouve une bouche d'entrée d'air et à l'intérieur duquel est placé une turbine solidaire d'une des roues du patin afin d'assurer son entraínement en rotation.US Patent No. 5,401,039 teaches to ventilate the internal volume of the hull by bringing air captured outside by holes made in the lower plane of the sole and this by means of a duct at the end of which is an air inlet mouth and inside which is placed a turbine secured to one of the wheels of the skate to ensure its rotational drive.

Il s'agit là d'une conception compliquée due au fait qu'elle conduit à la mise en oeuvre de pièces en mouvement. De plus, l'air est introduit dans la coque librement ce qui procure une aération diffuse ne tenant pas compte du fait qu'un pied en mouvement comporte des points de sudation bien particulier vers lesquels il faut diriger préférentiellement l'air de ventilation.This is a complicated concept due to the fact that it leads to the implementation moving parts. In addition, air is freely introduced into the hull which provides diffuse ventilation that does not take into account the fact that a moving foot has very specific sweat points to which it is preferable to direct the air of ventilation.

Le brevet US 2,751,692 concerne une chaussure dont la semelle comprend un volume d'air déformable sous l'effet de la pression exercée par le pied sur une semelle interne amortie.US Patent 2,751,692 relates to a shoe whose sole includes a volume deformable air under the effect of the pressure exerted by the foot on an inner sole amortized.

Le modèle d'utilité allemand DE-U-94 06 345 concerne un système de semelle déformable de chaussure favorisant la circulation d'air sous le pied.German utility model DE-U-94 06 345 relates to a sole system deformable shoe promoting air circulation under the foot.

Le brevet US 5,400,526 se rapporte à une chaussure de sport comprenant une semelle compressible au moyen de vessies en forme de bulbe compressibles afin d'assurer une ventilation pneumatique sous le pied. US Patent 5,400,526 relates to a sports shoe comprising a sole compressible by means of compressible bulb-shaped bladders to ensure pneumatic ventilation under the foot.

La demande de brevet WO 95/13716 se rapporte a une chaussure de sport munie d'un système anti-transpiration qui fonctionne selon le principe d'une semelle creuse déformable activée par une pression du talon.Patent application WO 95/13716 relates to a sports shoe provided with a anti-perspiration system which works on the principle of a deformable hollow sole activated by pressure on the heel.

Le brevet US 4,507,880 concerne une botte munie de moyens de ventilation sous forme d'un disque perforé logé sous la semelle.US Patent 4,507,880 relates to a boot provided with ventilation means in the form a perforated disc housed under the sole.

Le brevet US 3,624,930 se rapporte à une semelle interne comprenant des canaux de ventilation compressibles.US Patent 3,624,930 relates to an insole comprising channels of compressible ventilation.

Le brevet US 4,679,335 concerne une chaussure adaptée à la pratique de la bicyclette qui comprend des canaux de ventilation indépendants formés dans le support plantaire de la chaussure.US Patent 4,679,335 relates to a shoe adapted to the practice of cycling which includes independent ventilation channels formed in the plantar support of the shoe.

La demande de brevet WO 95/29605 se rapporte à un patin en ligne ayant une coque plastique aérée au moyen d'ouvertures ménagées sur le pourtour de la coque et des empiècements de rembourrage localisés aux endroits libres de toute ouverture.Patent application WO 95/29605 relates to an inline skate having a shell ventilated plastic by means of openings on the periphery of the hull and padding panels located in places free of any opening.

D'autres documents traitent de systèmes de ventilation comme le brevet US 5,390,941 ; US 4,939,851 ; US 3,012,342.Other documents deal with ventilation systems such as US patent 5,390,941; US 4,939,851; US 3,012,342.

La présente invention a pour objectif de remédier aux inconvénients précités et d'atteindre les résultats souhaités, venant d'être évoqués. Le but de la présente invention est donc de fournir un patin du type à roues en ligne amélioré, et notamment qui permette une bonne ventilation du pied et concilie tenue de pied, confort et légèreté.The present invention aims to remedy the aforementioned drawbacks and achieve the desired results, just mentioned. The object of the present invention is therefore to provide an improved in-line wheel type skate, and in particular which allows a good ventilation of the foot and combines foot holding, comfort and lightness.

A cet effet, elle concerne un patin à roues en ligne comprenant un châssis ayant une partie inférieure longitudinale sur laquelle sont montées des roues et une platine supérieure, une chaussure comprenant une tige surmontée par une semelle laquelle est fixée sur la platine supérieure du châssis, des moyens de canalisation de l'air s'étendant dans la direction longitudinale de la chaussure et comprenant au moins une zone de captage externe et une chambre de ventilation, ladite chambre de ventilation ayant un volume indéformable. Le patin est caractérisé en ce que les moyens de canalisation de l'air sont localisés dans une zone située au dessus de la platine supérieure du châssis et en ce que la chambre de ventilation s'étend sous un appui plantaire de la chaussure et en communication avec le volume interne de la tige.To this end, it relates to an in-line roller skate comprising a chassis having a longitudinal lower part on which wheels and an upper plate are mounted, a shoe comprising a upper surmounted by a sole which is fixed on the plate upper part of the chassis, air channeling means extending in the direction longitudinal of the shoe and comprising at least one external collection zone and one ventilation chamber, said ventilation chamber having a non-deformable volume. Skate is characterized in that the air channeling means are located in an area located above the upper plate of the chassis and in that the ventilation chamber extends under a plantar support of the shoe and in communication with the internal volume of the upper.

Avantageusement, ces moyens de canalisation de l'air sont constitués par une chambre de ventilation de volume indéformable ménagée sous un appui plantaire de la chaussure et en communication avec le volume interne de la tige.Advantageously, these air channeling means consist of a chamber non-deformable volume ventilation provided under the plantar support of the shoe and communication with the internal volume of the rod.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the characteristics which will emerge during of the description which follows, and which should be considered in isolation or according to all their possible technical combinations.

Le patin à roues en ligne 1 désigné dans son ensemble et représenté sur la figure 1 comprend d'une part un châssis 2 dont une partie inférieure longitudinale porte les roues 3 et d'autre part une chaussure 4 formée par une tige en forme de coque 5 rigide surmontant une semelle 6 destinée à être fixée sur une platine supérieure 7 du châssis 2, le volume intérieur de ladite coque 5 étant en communication avec l'extérieur de façon à obtenir la ventilation interne dudit volume par amenée d'air A, via des moyens de canalisation 8.The inline skate 1 designated as a whole and shown in Figure 1 firstly comprises a chassis 2, a longitudinal lower part of which carries the wheels 3 and on the other hand a shoe 4 formed by a rigid shell-shaped rod 5 surmounting a sole 6 intended to be fixed on an upper plate 7 of chassis 2, the internal volume of said shell 5 being in communication with the outside so as to obtain internal ventilation of said volume by air supply A, via channeling means 8.

D'une manière générale, les moyens de canalisation de l'air A, interposés entre une zone de captage externe et le volume interne de la coque 5, sont constitués par une chambre de ventilation 8 ménagée sous la semelle externe 6 définissant un appui plantaire 9 de la chaussure 4, et en communication avec le volume interne de la coque 5.In general, the air channeling means A, interposed between a zone of external collection and the internal volume of the shell 5, are constituted by a ventilation 8 provided under the outer sole 6 defining a plantar support 9 of the shoe 4, and in communication with the internal volume of the shell 5.

Selon l'exemple représenté sur les figures 1 à 4, la chambre de ventilation 8 est délimitée par le plan externe inférieur 6a de la semelle 6 de la chaussure 4 et par le plan supérieur 7a de la platine 7 du châssis 2, qui coopère en fermeture avec ledit plan 6a par l'intermédiaire d'un rebord périphérique de liaison 10 dans lequel est ménagée au moins une zone de captage 11 de l'air A. Cette chambre de ventilation 8, ménagée entre deux parties 6, 7, rigides, présente donc un volume indéformable.According to the example shown in Figures 1 to 4, the ventilation chamber 8 is delimited by the lower external plane 6a of the sole 6 of the shoe 4 and by the upper plane 7a of the plate 7 of the chassis 2, which cooperates in closing with said plane 6a by means of a peripheral connection rim 10 in which is provided at least one collection zone 11 of air A. This ventilation chamber 8, formed between two rigid parts 6, 7, therefore has an undeformable volume.

La zone de captage 11 est ici une bouche frontale formée par une interruption du rebord périphérique 10 entre l'avant de la platine 7 du châssis 2 et la semelle 6 du bout de la chaussure 4. Bien entendu, cette bouche d'entrée d'air pourrait être latérale voire même être combinée à plusieurs bouches frontales et/ou latérales. L'intérêt est que cette bouche d'entrée d'air soit positionnée sur une face du patin disposée perpendiculairement a la direction de déplacement, de façon que le courant d'air généré par le déplacement du patin s'engouffre directement à l'intérieur de la chambre de ventilation.The collection zone 11 is here a front mouth formed by an interruption of the rim device 10 between the front of the plate 7 of the chassis 2 and the sole 6 of the end of the shoe 4. Of course, this air intake mouth could be lateral or even be combined with several front and / or side vents. The interest is that this entry mouth air is positioned on a face of the shoe arranged perpendicular to the direction of displacement, so that the air current generated by the displacement of the skate engulfs directly inside the ventilation chamber.

La mise en communication de la chambre 8 de ventilation avec le volume interne de la coque 5 s'effectue par des trous 12 réalisés selon une disposition choisie sur l'appui plantaire 9, et en l'occurrence la semelle externe 6. Comme le montrent également les figures 2 et 3, la chambre de ventilation 8 peut être divisée par au moins une nervure longitudinale 13, de manière à constituer deux tuyères de canalisation 14, 15, de l'air capté A, et en regard desquelles sont ménagés une pluralité de trous d'aération 12.The communication of the ventilation chamber 8 with the internal volume of the shell 5 is made by holes 12 made in a chosen arrangement on the plantar support 9, and in this case the outer sole 6. As also shown in FIGS. 2 and 3, the ventilation chamber 8 can be divided by at least one longitudinal rib 13, of so as to constitute two pipe nozzles 14, 15, of the captured air A, and opposite which are provided with a plurality of ventilation holes 12.

Bien entendu, on peut très bien imaginer que soit réalisé un nombre de tuyères plus important. On peut également imaginer une seule tuyère.Of course, one can very well imagine that a greater number of nozzles be produced important. One can also imagine a single nozzle.

Selon une autre caractéristique de l'invention, représentée sur la figure 1, le fond 7a de chacune des tuyères 14, 15, de canalisation de l'air A comporte au droit de chacun des trous d'aération 12 des déflecteurs 16 destinés à créer des ressauts et tourbillons de l'air A afin d'augmenter sa vitesse d'écoulement et de favoriser son introduction forcée dans lesdits trous 12.According to another characteristic of the invention, represented in FIG. 1, the bottom 7a of each of the air ducting nozzles 14, 15 has at the right of each of the holes ventilation 12 of the deflectors 16 intended to create projections and vortices of air A so to increase its flow speed and to favor its forced introduction into said holes 12.

Par ailleurs, le plan interne supérieur 6b de la semelle formant l'appui plantaire 9 comporte une pluralité de nervures longitudinales 17 interrompues par des passages 18 de liaison entre elles de manière à constituer des couloirs en chicanes, favorisant la circulation et la répartition de l'air A sous le pied de l'utilisateur.Furthermore, the upper internal plane 6b of the sole forming the plantar support 9 comprises a plurality of longitudinal ribs 17 interrupted by passages 18 of connection between them so as to constitute corridors in baffles, promoting circulation and the distribution of air A under the foot of the user.

Ce premier exemple de réalisation de l'invention, avec collecte de l'air à l'avant, présente l'avantage de fournir une étanchéité bien meilleure par rapport à une construction avec des trous pratiqués directement sous la semelle ou directement sur la coque. Par ailleurs, l'introduction d'air est bien meilleure puisque la bouche d'entrée d'air se trouve directement perpendiculairement au flux de déplacement du courant d'air. This first exemplary embodiment of the invention, with air collection at the front, presents the advantage of providing a much better seal compared to a construction with holes made directly under the sole or directly on the shell. Otherwise, the introduction of air is much better since the air inlet mouth is located directly perpendicular to the flow of movement of the air stream.

Il est à préciser que l'extrémité arrière de la chambre de ventilation 8 peut comporter un bouchon 19 ou un clapet de fermeture à débit réglable afin de régler le débit d'air. Un tel clapet peut également être prévu à l'avant au niveau de la bouche d'entrée d'air.It should be noted that the rear end of the ventilation chamber 8 may include a plug 19 or an adjustable flow shut-off valve to adjust the air flow. Such a valve can also be provided at the front at the air intake opening.

Des variantes de réalisation basées sur le principe qui vient d'être décrit seront présentées sur les figures 5 à 9.Variant embodiments based on the principle which has just been described will be presented on the Figures 5 to 9.

C'est ainsi que selon les figures 5, 6 et 6a, la chambre de ventilation 8A est ménagée à l'intérieur de la semelle interne de la chaussure définissant un appui plantaire 9A à double paroi 9Aa et 9Ab formant un volume creux, d'épaisseur prédéterminée, rapporté à l'intérieur de la coque 5A sur le plan interne supérieur 6Aa de la semelle externe 6A.Thus, according to Figures 5, 6 and 6a, the ventilation chamber 8A is provided inside of the internal sole of the shoe defining a plantar support 9A with double wall 9Aa and 9Ab forming a hollow volume, of predetermined thickness, attached to the inside of the shell 5A on the plane upper inner 6Aa of the outer sole 6A.

Une telle conception permet non seulement de rendre amovible l'appui plantaire, pour le laver par exemple, mais peut constituer, en fonction du choix du matériau le constituant, un organe d'amortissement du poids du patineur.Such a design not only makes it possible to make the plantar support removable, to wash it by example, but may constitute, depending on the choice of the constituent material, an organ the weight of the skater.

Un tel appui plantaire 9A peut être obtenu par une opération d'extrusion soufflage d'une matière plastique, de façon indépendante du reste de la chaussure et donc amovible comme déjà cité.Such a plantar support 9A can be obtained by an extrusion blow-molding operation of a material plastic, independently of the rest of the shoe and therefore removable as already mentioned.

Dans ce cas, la bouche 11A d'entrée d'air A est obtenue au cours de l'opération d'extrusion sur l'appui plantaire proprement dit, et communique avec l'extérieur par une ouverture associée de la tige.In this case, the air inlet mouth 11A A is obtained during the extrusion operation on the plantar support proper, and communicates with the outside through an associated opening of the stem.

L'exemple de réalisation de la figure 7 diffère essentiellement des précédents en ce que la chambre de ventilation 8B se délimite entre un appui plantaire 9B rapporté à l'intérieur de la coque 5B et le plan interne supérieur 6Ba de la semelle 6B avec lequel il coopère en réalisant un écartement prédéterminé "e" par l'intermédiaire de nervures verticales longitudinales 20 issues de l'appui plantaire 9B. L'écartement "e" pourrait également être obtenu par l'intermédiaire d'une zone périphérique adjacente de l'appui plantaire 9B (non représentée sur le dessin).The embodiment of FIG. 7 essentially differs from the previous ones in that the chamber of ventilation 8B is delimited between a plantar support 9B reported inside the shell 5B and the plane upper internal 6Ba of the sole 6B with which it cooperates by achieving a predetermined spacing "e" by means of longitudinal vertical ribs 20 coming from the plantar support 9B. The spacing "e" could also be obtained by means of an adjacent peripheral zone of the plantar support 9B (not shown in the drawing).

Dans ce cas, l'écartement "e" entre l'appui plantaire 9B et le plan interne 6Ba de la semelle 6B formant la chambre de ventilation 8B est donné par le rebord périphérique interne 20 dudit appui plantaire.In this case, the spacing "e" between the plantar support 9B and the internal plane 6Ba of the sole 6B forming the ventilation chamber 8B is given by the internal peripheral rim 20 of said support plantar.

Dans l'exemple des figures 8 et 8bis, la différence réside dans le fait que l'écartement "e" entre l'appui plantaire 9c et le plan interne 6Ca de la semelle 6C de la chaussure formant la chambre de ventilation 8C est donné par des nervures longitudinales verticales 21 issues dudit plan interne 6Ca de la semelle 6C, sur le sommet desquelles repose l'appui plantaire 9C et dont les parois latérales forment des tuyères de canalisation 22, 23, 24, 25,..., de l'air A, en regard desquelles sont ménagés une pluralité de trous d'aération 12.In the example of FIGS. 8 and 8bis, the difference lies in the fact that the spacing "e" between the plantar support 9c and the internal plane 6Ca of the sole 6C of the shoe forming the ventilation 8C is given by vertical longitudinal ribs 21 coming from said internal plane 6Ca of the sole 6C, on the top of which rests the plantar support 9C and whose side walls form pipe nozzles 22, 23, 24, 25, ..., of air A, opposite which are formed a plurality of ventilation holes 12.

Une bouche 11C d'entrée d'air A est ménagée également à l'extrémité avant de la coque au-dessus de la semelle 6C.An air inlet mouth 11C A is also provided at the front end of the shell above of the sole 6C.

Enfin, selon le mode de réalisation des figures 9 et 9bis, la chambre de ventilation 8D est constituée par une semelle creuse 6D définissant un double fond obtenu au cours d'une opération de moulage de ladite semelle et dont le plan supérieur constitue l'appui plantaire 9D.Finally, according to the embodiment of Figures 9 and 9bis, the ventilation chamber 8D is constituted by a hollow sole 6D defining a double bottom obtained during a molding operation of said sole and the upper plane of which constitutes the plantar support 9D.

De même, une bouche 11D d'entrée d'air A est prévue frontalement sur ladite semelle 6D. Similarly, an air inlet mouth 11D A is provided frontally on said sole 6D.

Un tel mode de réalisation est particulièrement adapté à une construction de tige 5D souple assemblée par collage, de façon connue en soi, à la semelle 6D obtenue de façon indépendante par moulage.Such an embodiment is particularly suitable for a flexible 5D rod construction. assembled by gluing, in a manner known per se, to the sole 6D obtained independently by molding.

Bien entendu, l'appui plantaire délimitant le plan supérieur des chambres de ventilation pourra être conçu de toutes autres façons comme par exemple par assemblage de plusieurs éléments.Of course, the plantar support delimiting the upper plane of the ventilation chambers can be designed in any other way, for example by assembling several elements.
