Liner for ski boots and an assortment of liner

The invention relates to ski boots with an outer shoe and. removable inner shoe and is concerned with the task of improving the fit of the inner shoe and at the same time simplifying the manufacture of the same in such a way that the provision of the range of sizes and widths required in practice with '_ .; ·, is essential 'can be' secured 'at a lower cost than before .. ^: can,''_ ■ ...: ■

The previously common inner shoes for ski boots are made of artificial ■ '^; fabric or leather blanks of uniform thickness produced by gluing or sewing, the shaft inside locally, especially -: -. Especially in the ankle area, it is padded with foam inserts. Inner shoes of this type ensure good adaptation to the anatomical shape of the foot only in the padded areas. In addition, they can only be produced with a relatively large amount of work and expense and require the various,

different sizes of the leather or Plastic parts as well as careful work when sewing or gluing these parts and when attaching the upholstery.

It is also very difficult to achieve a fine gradation to the different foot sizes for an outer shoe of a given size by varying the inner shoe, because this is only possible by changing the local padding. and the foot with thick local padding in the other ■: 'areas. no longer finds proper support "" [■

According to the invention, the disadvantages of the. hitherto known inner shoes for ski boots avoided in that the inner shoe is molded in one piece from foamed plastic or: rubber, the outer side of the inner shoe being adapted to the inner side of the outer shoe and the inner side of the inner shoe to the anatomical shape of the foot: so that ■ the Wall thickness of the inner shoe both in the shaft and in the '■ sole area is locally different.

Due to the one-piece design of the inner school with adaption If its inner shape is adapted to the anatomical shape of the foot, the entire foot is given a good grip in all places. and in particular, just below the ... Ankle and above the calcaneus a warid thickening of the ' Inner shoe that gives the foot an ideal heel hold.

For the production of the inner shoe a branch, divided hollow form used, the dividing line in the central. , plane of the shoe and into which a one-piece core '·' is used. The inside of the hollow shape corresponds to visibly their design of the inside of the outer shoe, ■ · for which the inner shoe is intended, whereas the surface of the core is shaped according to the anatomical shape of the foot is. In an outer shape of a predetermined size, which corresponds, for example, to the English shoe size 8, '- ;.

alternatively, two or more cores can be used, which are more finely graduated than the nominal sizes of the outer shoes. For example, the nominal sizes of the outer shoes on the numbers 7j 8 and 9 stepped so cores can be inserted into the associated hollow shapes that either liners for nominal sizes 7 »8, 9 or liners for the nominal sizes of 7 ^1/2, 8 '/ 2 , 9 ^1/2 indicate only the average γ / andstärke the larger number by a half liners each bit is reduced.

In an analogous manner, for each inner shoe size, for example for the. Sizes 8 and 8i / 2, two or more cores are used, the <■ are made with various ball length, for example having a narrow, medium and wide ball area, so that, for each inner shoe size, for example 8 or 81/2, respectively versions for narrow, medium or wide feet can be produced.

In all of these cases the desired anatomical view results The shape of the inside of the inner shoe that is adapted to the shape of the foot directly through the molding process, i.e. it is not of the. Skill of workers dependent.

According to the invention, a range of sizes of inner shoes can thus are produced, the characteristic of which is that for each of the graduated outer shoe sizes two or more inner. shoes with the same external size, but by varying the wall thickness graduated in fractions of the gradation of the external size Inner size (foot size) are provided. In the same way, a wide range of inner shoes can be produced whose ' It is characterized by the fact that for each inner shoe size several, ·., Inner shoes with by varying the wall thickness in the ball area differently dimensioned bale widths, e.g. narrow, medium and wide inner shoes are provided.

Since the inner shoes can alternatively ground τ / inserted into the outer shoes as required, there is the commercial advantage of ';' that the storage of outer shoes, which is very expensive "

The range only needs in terms of the much cheaper and less space-consuming inner shoes with the increased diversity will.

A Fut-P is preferably placed on the inside of the inner shoe ter made of plastic or thin leather, which can be done very easily in the v / eise that the inner lining on a last is pulled up and coated with an adhesive, whereupon the inner shoe on which the inner lining is carried ■ is placed on the lower edge.

'' Fastening means, e.g. Velcro fasteners or snap fasteners, are attached in a known manner to the upper outer edge of the upper of the inner shoe provided, with which the inner shoe can be detachably fixed to the shaft of the outer shoe.

An embodiment of the invention will now be referred to ^ explained on the drawings.
