Patent

CA 2199012

A shoe has a sole (3) and an upper (2). The border of the sole (3) has at least in sections a profile (7) associated to a complementary profile (8) of the upper (2). The profile (7) and the complementary profile (8) are form- fittingly interconnected by a plurality of mutually spaced joining elements (9) such as locking lugs, hooks, rivets, pins, screws, soulderable studs or the like. A shell type shoe of this type may be easily produced by injection moulding two partial sections (52a, 52b) of the upper (2) each in a separate mould (54a, 54b), for example in a plastic material, then by joining them with each other and with a sole (3). Appropriate moulds for producing the partial sections are disclosed.

Une chaussure comprend une semelle (3) et une tige (2). Au moins des sections de la bordure de la semelle (3) ont un profil (7) auquel correspond un profil complémentaire (8) de la tige (2). Le profil (7) et le profil complémentaire (8) sont reliés l'un à l'autre par liaison de forme au moyen d'une pluralité d'éléments de liaison (9) mutuellement espacés, tels que des taquets d'arrêt, des crochets, des rivets, des chevilles, des vis, des goupilles soudables ou similaire. Une chaussure monocoque de ce type peut être aisément produite par moulage par injection de deux sections partielles (52a, 52b) de la tige (2), par exemple en plastique, chacune dans un moule (54a, 54b), puis par leur assemblage mutuel et avec une semelle (3) en une seule opération. L'invention concerne également des moules appropriés pour produire les sections partielles.
