  • FIG. 6 shows a sectional view of the receiving element 6. It can be seen that each wheel 3 is mounted in a bearing block 4, which is constructed as a U-shaped wheel cage. An elastomeric damping material 37 is provided between the bearing block 4 and a metal support 36 of the receiving element 6, which is also U-shaped in cross section, and determines the damping properties of the wheels 3 relative to the receiving element 6. It should also be pointed out that the connecting rod 31 in the front region, ie in the region of the hook element 26, is bent downward towards the front wheel 3, so that the entry with the shoe 1 and its locking element 23 can take place downwards, as is the case is also the case with ski bindings, for example. This makes handling the inline skater more convenient.

Abstract

L'invention concerne un patin à roulettes en ligne comprenant une chaussure (1) comportant une semelle (2) et plusieurs éléments de roulement disposés dans la zone de la semelle et montés rotatifs les uns derrière les autres dans le sens longitudinal de la semelle (2), dans des paliers (4). Les pivots (5) des éléments de roulement s'étendent à angle droit par rapport au sens longitudinal de la semelle (2). Les paliers (4) font, conjointement avec les éléments de roulement, partie intégrante d'un élément de réception(6) et la chaussure (1) est fixée de manière amovible sur l'élément de réception (6). Afin de réaliser un patin à roulettes en ligne, qui présente une chaussure (1) amovible, facile et rapide à fixer ou à enlever, et comportant par ailleurs des propriétés remarquables en termes de marche, lorsqu'elle est désolidarisée du patin, notamment un degré de dureté globalement habituel dans les chaussures de sport connues, sans que la manipulation du patin à roulettes en ligne ne soit affectée par la chaussure (1) sensiblement souple, il est prévu que ladite chaussure (1) présente, au moins dans la zone de la semelle (2), un élément de renforcement (11) conçu de manière spécifique à la forme et/ou au matériau, de manière à être souple dans le sens de roulement habituel du pied et à être rigide et/ou semi-rigide, aussi idéalement que possible, dans le sens opposé.
