Description

The invention relates to a ski boot with at least one shaft made of leather with a molded sole made of elastic Material.

In the case of highly stressed footwear such as ski boots, high demands are placed on durability and tightness posed. In the case of ski boots, special conditions are required insofar as through the commonly used ski bindings place excessive mechanical stress on the connection between the sole and shaft are exercised. Furthermore, it must be taken into account that a change in shape is caused by ski boots Expanding is extremely undesirable because the foot must sit as firmly and immovably in the boot as possible.

In itself, leather is relatively high quality as a material for Ski boot shafts are well suited, as leather clings tightly to the foot or the lower thigh. Also will Leather is preferred as the upper material for aesthetic reasons.

However, there are disadvantages to the leather material for ski boot shafts to the extent that * leather is relatively expensive is and on the other hand also not the desired resistance to mechanical Has stresses and especially against moisture. Ski boot uppers made of leather must therefore be special carefully maintained. Nevertheless, it cannot be avoided that the leather shafts gradually become special in the area facing the sole due to mechanical and moisture influences in appearance and their Properties decrease sharply

A particular difficulty with ski boot shafts made of leather is that the one that is absolutely desirable in itself Dimensional stability not of sufficient durability? is · Due to the constant use in conjunction with the accumulation of moisture the ski boots or the shafts are gradually widened so that the ski boot does not is more firmly attached to the foot.

The invention is based on the object of improving ski boots with at least one shaft made of leather and to develop further so that the aforementioned disadvantages are avoided. To solve this problem is Proposed by the invention that the sole with a molded or glued all around running ,, the shaft Deformation protection strips supporting clay on the outside

can be seen, which preferably extends into the area above the toes. The invention therefore provides that the shaft is protected on the outside in the most stressed area by a strip running all the way around especially against mechanical stresses, for example from the ski bindings, through the steel edges of the skis etc. The perforation protection strip expediently consists of an elastic material, preferably of the same material like the molded sole of the ski boot. This also ensures particularly good protection against the effects of moisture.

A ski boot according to the invention has great dimensional stability, although the upper requires little care in the area of the greatest stress, namely in the area of the deformation protection strip. As a result, the upper can also be made of less high-quality leather, so that the production of the ski boot is overall cheaper than known ski boots with the upper parts described at the beginning.

Another feature of the invention is that the anti-deformation strip at its base on the sole is wide in cross-section and tapers upward. As a result, with the protective strip having good resistance, relatively little material is required

and achieved a low dead weight. At the upper edge of the deformation protection strip a smooth one is created Transition to the yoke, which is favorable to the exterior of the ski boot influenced. In addition, there is no risk of entanglements during use.

It is also new and advantageous that an all-round lower part of the shaft facing the sole is made of a material deviating from the rest of the part (upper part), in particular made of suede, textile material or the like and the deformation protection strip up to above the connection point between the upper part and the lower part of the shaft enough. This proposal enables the use of less expensive shaft material in the area of the Deformation protection strip. The connection point between the two parts of the shaft is approximately here in height above the toes of the feet.

According to a further proposal of the concept of the invention, the shaft only has an upper part that is connected to the upper g area of the deformation protection strip and, moreover, by means of a lining known per se 4h the lower area of the deformation protection strip and the sole is connected. Following this proposal will completely dispensed with the lower part of the shaft. Instead of this lower shaft part, the Deformation protection strips soaked up from the sole.

Shaft 10 is suitably a sole 17 made of elastic material, for example rubber or plastic molded, molded or vulcanized.

According to the invention is to protect the most stressed and endangered part of the shaft 10, a deformation protection strip running around the shaft is determined, which is also expediently made of elastic material, in particular of the same material as the sole 17. This circumferential deformation protection strip 16 can molded together with the sole 17, vulcanized, or. be molded, but also attached by hand will.

After that in Pig. The embodiment of the invention illustrated in FIG. 2 is the one formed together with the sole 17 Deformation protection strips 16 on the up to the sole Reaching shaft 10 molded, so practically placed on the outside. The lower edge of the shaft 10 is conventional Connected to an insole (5), there is also a suitable putter on the inside of the shaft 10 21 is provided, which is also connected to the insole 15. Between the insole 15 and the injection-molded Outsole 17 is an insert 13, e.g. made of mushroom or the like.

The configuration according to Pig.3 is particularly advantageous. Here is how with the ski boot according to Pig. 2, the deforma-

rungsBeckutzstriene outside on the continuous down to the bottom Shank 10 attached In cross-section, however, this deformation protection strip 16 is designed so that at the base, that is to say at the connection point to the sole, a relatively wide cross-section arises which tapers upwards, so that the deformation protection strip 16 merges into the plane of the shaft 10 without a significant shoulder. This makes a more resilient Durable cross-section of the deformation protection strip 16 achieved without thereby adversely affecting the outer shape of the ski boot or the shaft.

A special feature of the invention is in Pig. 4 shown Here the shaft 10 consists of two parts, namely an upper part 11 and a lower part 12. The upper part 11 consists of the usual high-quality leather, while the lower part 12 consists of another material, for example leather, textile material or the like. This material can be cheaper than having the rest Sähaftmaterial and special Kerkmale such as mechanical strength, adaptability when worn, etc. The lower edge H of the lower part 12 is connected IAIT the insole 15 and UEN at the top by a seam 13 with the upper part 11 shank .
