Definitions

  • the present invention relates to a shoe provided with a locking device, in particular sports, leisure or rehabilitation shoes, with a shaft material which is flexible with respect to tensile stresses in the closing area or with a plurality of flexible shaft materials according to the preamble of claim 1.
  • a sports shoe, namely soccer boots, with a closing device of this type is known from DD-PS 89 796.
  • each side of the instep shield can be tied by a lacing in the instep area, each with a tab provided on the side parts of the shoe upper, in that a shoelace is threaded through lacing holes in the instep plate and in the side flaps and can be tied behind the heel part of the football boot.
  • the present invention is intended to solve the problem of improving this known double lacing in the instep area in such a way that it is possible for the instep shield and the side parts of the shoe upper to be closed over the entire closing area in a simple manner and with closing that is as uniform as possible - or clamping force against each other in order to ensure the most uniform possible pressure distribution along the entire closing area, if possible also over the area of the arch of the instep of the foot, that is to say transversely to the longitudinal direction of the shoe.
  • the present invention ensures that the mutual position of the tensioning element guides in the riser plate or in the closing flap is precisely defined and optimized with respect to one another and that the tensioning element (s) is not pinched by the closing pressure of the riser plate and the closing flap or will not be selective and / or in partial areas of the closing area.
  • a largely continuous adjustment of the bracing is possible in a simple manner by means of the central turnbuckle.

  • one or more crossings of the tensioning element (s) can also be present.
  • a special configuration of the intersecting grooves ensures that the clamping element (s) crosses with little or no friction in these embodiments of the present invention, since these can be designed such that they do not lie on one another at any point.
  • the locking device can be easily tensioned and relaxed, and wear by avoiding high pressure at the point of intersection of the clamping element (s) is also completely avoided.
  • the use of elastic or resilient material for the closing device results in a relatively stable end edge at the shoe opening at the end of the closing area. This can i. Further development of the invention serve, through a special configuration of the tongue end part to stabilize or fix the position of the tongue with respect to the closing device and also to allow targeted guidance of the opening or closing upper end parts of the shoe upper.
  • DE-AS 20 46 890 discloses the use of central turnbuckles as a locking device for ski boots with shell-shaped plastic locking flaps in the closing area which are practically non-compliant with regard to tensile stresses.
  • this type of locking device is not applicable to shoes with shaft materials which are flexible with respect to tensile stresses in the locking area, since the locking area of the previously known locking devices extends to only a short section of the locking tabs of these rigid ski boots for alpine skiing.

Abstract

Une chaussure comprend un dispositif de fermeture, une tige en un matériau déformable par rapport aux efforts de tension au niveau de la zone de fermeture et une lame de protection du coup-de-pied susceptible d'être fixée des deux côtés aux pièces latérales de la tige de la chaussure. Afin de serrer la lame de protection du coup-de-pied et les pièces latérales de la tige de la chaussure sur toute la zone de fermeture avec une tension ou force de fermeture aussi uniformes que possible, l'extrémité (5) de la lame (2) de protection du coup-de-pied plus proche de la pointe de la chaussure est reliée à des languettes de fermeture (3, 4) élastiques qui s'étendent parallèment des deux côtés de la lame (2) de protection du coup-de-pied, ou qui forment avec celle-ci un angle aigu réduit (alpha), ou bien ces pièces (2; 3, 4) forment chacune un élément séparé. La lame (2) de protection de coup-de-pied est pourvue d'un tendeur central (12) qui permet aux languettes de fermeture (3, 4) et aux pièces latérales (6, 7) de la tige (8) de la chaussure de se déplacer par rapport à la lame (2) de protection du coup-de-pied par l'intermédiaire d'au moins un élément tendeur (11). Finalement, l'élément tendeur (11) relie sans croisements les languettes de fermeture (3, 4) avec la lame (2) de protection du coup-de-pied au moins dans les parties supérieure et inférieure (27, 28) de la lame (2) de protection du coup-de-pied.
