Abstract
Description
Le présent Certificat d'Addition concerne une variante apportée à la chaussure à effet de "tremplin" faisant l'objet du
Brevet Principal.This Certificate of Addition concerns a variant made to the "springboard" shoe which is the subject of
Main patent.
Selon le Brevet Principal, la semelle comporte une zone formant tremplin formée par le superposition d'une série de boudins légèrement décalés l'un par rapport au suivant, et délimitant intérieurement des évidements ; au surplus il est également prévu que lesdits boudins partent de la partie médiane de la semelle et sont légèrement écrasés vers la partie arrière, de manière à provoquer un relèvement de la semelle vers l'arrière. According to the main patent, the sole has a springboard area formed by the superposition of a series of flanges slightly offset one relative to the next, and internally delimiting recesses; furthermore, it is also provided that said flanges leave from the middle part of the sole and are slightly flattened towards the rear part, so as to cause the sole to rise up towards the rear.
I1 est apparu à la Déposante que l'effet recherché peut être obtenu en garnissant l'évidement des boudins au moyen d'un matériau spongieux. Au surplus, il est également apparu que l'un au moins des boudins peut constituer un intercalaire, partant depuis la zone avant de la chaussure, en étant protégé par le relèvement de la couche d'usure jusque vers la mi-hauteur du devant de l'empeigne. Enfin, sur un plan d'efficacité pratique, la superposition de deux "boudins" seulement est apparue suffisante pour obtenir l'effet technique recherché ; si l'esthétique l'impose, des bandes suggérant la périphérie de boudins additionnels peuvent'être ajoutées autour du talon, mais elles peuvent ne pas participer à l'effet "tremplin". It appeared to the Applicant that the desired effect can be obtained by filling the recess of the tubes with a spongy material. In addition, it also appeared that at least one of the flanges can constitute an interlayer, starting from the front zone of the shoe, while being protected by the raising of the wear layer up to mid-height of the front of the upper. Finally, in terms of practical efficiency, the superposition of only two "tubes" appeared sufficient to obtain the desired technical effect; if the aesthetics so dictate, bands suggesting the periphery of additional flanges may be added around the heel, but they may not participate in the "springboard" effect.
On va décrire cette variante de l'invention en se référant au dessin annexé représentant en perspective ladite variante, appliquée à une chaussure basse, du type "jogging". This variant of the invention will be described with reference to the attached drawing showing in perspective said variant, applied to a low shoe, of the "jogging" type.
Sur ce dessin, on retrouve, comme dans le brevet principal, une semelle se composant d'une couche d'usure 1, et de la zone formant tremplin 2. In this drawing, we find, as in the main patent, a sole consisting of a wear layer 1, and the springboard area 2.
Selon l'invention, cette zone 2 se compose, de bas en haut, d'un intercalaire 4, courant sur pratiquement toute la longueur de la chaussure et d'un boudin 5, partant de la partie médiane jusqu'au talon. According to the invention, this zone 2 is composed, from bottom to top, of an insert 4, running over practically the entire length of the shoe and of a flange 5, starting from the middle part up to the heel.
L'intercalaire 4 est, selon l'invention, réalisé en mousse de matière plastique, et présente vers l'avant de la chaussure, une portion amincie 6, recouverte par un retour 7 de la couche d'usure, venant recouvrir approximativement la moitié de la hauteur de l'empeigne 8. I1 est également légèrement aminci en 9 sous le talon, pour définir une légère remontée de celui-ci. The interlayer 4 is, according to the invention, made of plastic foam, and has towards the front of the shoe, a thinned portion 6, covered by a return 7 of the wear layer, coming to cover approximately half of the height of the vamp 8. I1 is also slightly thinned in 9 under the heel, to define a slight rise of the latter.
Le boudin 5 part approximativement du milieu de la chaussure, où il s'amincit en 10, pour se terminer à hauteur du talon, en étant légèrement plus court que l'intercalaire 4 de la couche d'usure 1. The flange 5 starts approximately from the middle of the shoe, where it thins out at 10, and ends at the heel, being slightly shorter than the interlayer 4 of the wear layer 1.
La portion 11 de l'empeigne entourant le talon est ellemême légèrement décalée vers l'intérieur, de sorte que l'ensemble de la chaussure est décalé vers l'avant d'un angle OC à partir de la couche d'usure, comme c'était déjà le cas dans la réalisation décrite au Brevet Principal. The portion 11 of the vamp surrounding the heel is itself slightly offset inward, so that the entire shoe is offset forward by an angle OC from the wear layer, as c was already the case in the embodiment described in the Main Patent.
Toutefois, l'efficacité de la semelle à jouer son rôle de "tremplin" étant assurée à un degré suffisant par les deux couches de mousse 4 et 5, les bandes représentées en 12 et 13 autour de la portion 11 située au-dessus de la zone d'application de la pression du pied peuvent n'être que superficielles, simulant des boudins additionnels factices n'ayant qu'un rôle décoratif. However, the effectiveness of the sole to play its role of "springboard" being ensured to a sufficient degree by the two layers of foam 4 and 5, the bands shown at 12 and 13 around the portion 11 located above the foot pressure application area may be only superficial, simulating additional dummy tubes having only a decorative role.
Bien entendu le nombre précis de boudins réels en mousse et de boudins superficiels factices pourrait varier, l'invention visant essentiellement le fait qu'avec le nombre minimum de deux boudins réels l'effet "tremplin" est assuré. Of course, the precise number of real foam tubes and artificial surface tubes could vary, the invention essentially aiming at the fact that with the minimum number of two real tubes the "springboard" effect is ensured.
