Description

Shoe tongue, especially for ski boots with Clamp locks.

The invention relates to a shoe tongue, in particular for ski boots with tension lever closures, with the tongue with a preferably made of foam Abpol--. is provided.

In the known shoe tongues of this type, the cushion layer is covered on the outside by a cover made of soft material, generally leather. This means that the high specific pressures occurring when the clamping lever locks are closed, in the area of the clamping lever bearings, even if the padding layer is relatively thick, cannot be absorbed by the padding layer so far that no annoying or painful effects on the puss occur. This has always been seen as a disadvantage of ski boots with tension lever locks. In order to remedy this disadvantage, various measures have been proposed with regard to the design of the fasteners, such as, for example, an enlargement of the ajif riveted on the shaft

Base plate of the closures. However, these dimensions have proven to be inadequate for the purpose of the clamping lever bearing to keep outgoing pressure completely away from the foot.

The invention now takes a different approach to eliminate the aforementioned disadvantage. She is namely on a new design directed to the tongue of the shoe. In this context, the invention also has the further object of the To remedy the lack of known shoe tongues resulting from it shows that by the external, in general The leather cover of the upholstery shows moisture can penetrate into this, which makes the comfort essential and the dynamic spring characteristics of the upholstery are weakened.

The invention now proposes that the padding of the sebu tongue to the outside through a curve adapted to the junction, Moisture-impermeable molded part made of hard material is covered, the molded part forming a permanent part of the tongue. The molding preferably orders from a plastic injection molded part made of polystyrene or Hard PVG can be made; it can be considered a continuously trained Solid body, provided with recesses or designed as a hollow body, which is made in one piece or can be glued together from two appropriately shaped shells.

As a result of what is provided in the scope of the invention

hard standard part, the high pressures occurring at the clamping lever bearings over the entire surface of the shoe tongue
be evenly distributed that no longer as before
Pressure pain in the foot occurs. The shape of the molded part results from the shape of the foot. On its outward-facing side, the molded part is accordingly concave in the upper region of the back of the foot and convex in the transverse direction thereto.

Since the molded part is impermeable to moisture, the
padding generally formed from a foam
no moisture can penetrate.

In the drawing, the shoe tongue according to the invention is based on explained by examples. Show it

FIG. 1 shows a tongue in longitudinal section with a molded part designed as a continuous injection molding;

Figure 2 shows a section along the line H-II of Figure 1 and
FIG. 3 shows a sectional illustration corresponding to that in FIG. 2 through a tongue with a molded part designed as a hollow body.

The upholstery layer denoted by 1 is covered on the outside with a molded part 2 or 2 ′ according to the invention, which in turn is provided on its outer side with a cover 3, which consists for example of leather
can. Such a cover 4 is also on the inside

the side of the padding 1 is available. The covers 3, 4 can form a pocket which the molded part 2 or 2 ' and the cushion layer 1 receives. Of course, the individual layers of the shoe tongue can also be in other suitable Way, e.g. be held together by gluing. Due to the standard part, the shoe tongue is given a puss overall Adapted design, which counteracts a shifting of the tongue on the puss from the start.

That used in the embodiment according to FIGS Molded part 2 is designed as a continuously solid molded part. In contrast, Figure 3 shows the Use of a molded part 2 'designed as a hollow body, whose shells 6 and 7 enclosing the cavity 5 are different Have bulges. Such a design of the molded part is quite generally the possibility of a high To achieve flexural strength with economical use of material and with different curvature of the top and bottom to avoid undesirable deviations in the wall thickness in terms of injection molding

The invention is not limited to the following claims. It includes all the features from the above Description and the drawing, which are obviously inventive based on the prior art.
