Abstract

The invention concerns a shoe, in particular a shoe for sport, leisure or rehabilitation purposes, with a centrally positioned clasp mounted on a dimensionally stable instep covering which can be moved towards or away from the instep. The clasp is designed so that it can be used with shoes having uppers made of material which is flexible with respect to tensional forces, i.e. with shoes which do not have dimensionally stable sheath-like uppers. This is achieved by virtue of the fact that the centrally positioned clasp (24) is fitted on a mounting plate (23) which is attached to a flexible tongue (15). The mounting plate (23) is significantly smaller than the length on the instep (26), thus allowing substantial parts of the tongue (15) to remain flexible.

Description

The present invention relates to a shoe of the type defined in the preamble of claim 1 with a central fastener.

A shoe of this type is known from German Utility Model U-8912788. In this case, an upper cover made of a hard elastic material is provided on the soft elastic tongue. The instep cover is pivotally mounted on the front section of the shoe with laterally pivotable closing ears, each of which is rigidly connected to a lateral part of the upper. A central fastener is rigidly attached to the upper cover, i.e., is permanently attached to the upper cover. From the central fastener, at least one string-like tightening element is alternately guided via the closing tab and the turning element of the upper cover. The central fasteners, upper cover and closure earpieces are pre-manufactured and inspected to ensure a functioning technical one
Form one unit.

German Patent Application DE-A-2 341 658 also discloses a shoe with a central fastening and a tongue-shaped central upper, in which the central upper is hinged at the tip for the purpose of easy shoeing. Connected to the front of the shoe. A central fastener is provided on the center shoe upper in the form of a toggle that can rotate about the center of the shoe upper. Up and down from the central fastener, a lace extends substantially sideways toward the central upper. The lace forms a loop on the outside, returns laterally through the center shoe upper, and on the other side edge of the center shoe upper at the level of the first loop, respectively, based on the formation of another loop on the center shoe upper. It is fixed to. The opposing loops are located within the fold at the end of the instep, ie within the joint at the transition to the shin.
The other two loops are provided in the area of the ball of the toe or the joint of the toe. The hook is integrally formed with the upper material of the ski boot. The loops are arranged via hooks in the layer of the central shoe upper, which is pivotally attached to the shoe upper, and the rotation of the toggle tightens the tightening lace via a lace roller connected to the toggle, thereby closing the ski boot tightly . in this case,
The tension acts in a direction perpendicular to the direction of extension of the center shoe upper, and the center shoe upper overlaps the side shoe uppers. Although this makes it possible to put on good ski shoes, it is troublesome and time-consuming to tie the hooks when closing the ski boots, which is a problem particularly in hooks closed with snow or ice. is there.

The object of the present invention is therefore to improve a shoe with a central fastening of the type mentioned at the outset, in which the central fastening can be easily replaced like a shoelace of a conventional shoe, in which case the foot, in particular In order to allow a good fit of the shoe in the instep range, the foot should be in the area of the toe joints and the upper and lower talar joints, despite the good fixation of the foot in the shoe. The goal is not to limit the possibility of movement.

This problem has been solved by the features of claim 1.

With the arrangement according to the invention, the shoe is able to flex and resilient in the region of the toe joint, and the tongue, in particular the material of the tongue, is of a soft elastic construction so that the instep of the foot, i.e. Good fit for curvature. Important for non-Alpine ski shoes, as the retaining plate for the central fastener does not completely cover the instep length, but the lower part of the tongue is open and thus maintained elastically Possibility of movement of the foot is guaranteed in the area of the toe joint. This is also true for the mobility of the upper and lower talar joints on the basis of the length dimension of the holding plate, and such mobility is also present in shoes of the type covered by the present invention--also in Alpine ski shoes. On the contrary-must not be impaired and must never be excluded.
