Process for the manufacture of footwear

The invention relates to a method of manufacture Clay footwear, in particular for ski boots, of plastic or rubber in forms

There are a large number of methods of manufacture Known of ski boots made of materials that can be processed in the molding process, the ski boots either from a mold or the like, are formed or by injection molding getting produced·

The known methods all have the disadvantage which is particularly uncomfortable in the case of ski shoes that the shoe cannot have a split shaft, its parts overlap at the edge when closing the shoe.

The object of the invention is to provide a method for the production of footwear, in particular of ski boots, to create the production of footwear and / or ski boots made possible, the upper part of which resembles that of the usual leather shoes

109 882/046 U

This object is achieved according to the invention in that first two halves corresponding to the vertical Longitudinal median plane of the shoe made separately in molds and these halves are connected to each other

With this method, the two halves can be given any shape in the shaft part, i.e. the shaft parts of the two halves can go beyond the vertical longitudinal plane or »the vertical connecting plane, so that they can overlap with their ribbons.

Ψ The connection of the two halves can be done in any way according to the material used for the halves, in particular hot welding or gluing with vulcanization can be used

The joint lines of the two halves can be covered by cover strips, whereby their shape and / or the appearance of the shoes and also the tightness of the connections is improved by color.

IM to facilitate the joining of the two halves, the sole part of one of the two halves is provided with lateral pegs that are inserted into blind holes in the side wall of the Fit the sole part of the other half.

The drawing illustrates the method according to the invention. It shows:

4 shows a cross section through a sole part with indentations or grooves on the upper surface - on a larger scale}

5 shows a view of the finished ski boot from behind

As already noted, in making a ski boot according to the invention, first two separate halves of the type illustrated in Fig. 1 are made * Each half is obtained by injecting rubber or a plastic (e.g. polyvinyl chloride) into a corresponding mold * Each half contains one upper part 1, which corresponds to the front and rear part of the upper or upper of a conventional shoe, which is cut through, so to speak, in the longitudinal axis of the shoe, and a lower part 2, which accordingly forms half the sole. As is apparent from Figure ₀ 2 and 3, the two halves with 1.2 or 1 'and 2 * denotes "The rear portion of the shank part 1, respectively, 1 * has the usual bulge for the ankle of the wearer of the shoe, while the Front sections 3 »3 ^f encompass the front foot part overlapping one another and are provided with closing means 4,4 * in the form of buckles. Top of the upper part 1, thus at one-half, extensions are provided in the form of Eiemen 5, for which the other shaft part 1 ^f is provided with the corresponding closing ·

The lower part or sole part 2 of one of the halves is provided with lateral pegs 6 (FIG. 3) which are arranged transversely so that they ^{fit into blind holes 6 'in the side wall of the sole part 2 1 of} the other half the exact centering of the two halves during the connection process · The connection

can be implemented in any way, for example by. Heat welding, if it is a plastic or by gluing and vulcanizing} if it is rubber. The connection is made on the vertical rear hand of the two shaft parts 1 and 1 * and below on the front hand of the same. Of course, also the longitudinal surfaces of the sole portions 2 and 2 ¹ are connected · The surge lines of the two halves are covered by cover strip 7 (FIG x 5), which can have any shape and color _e The shoe is further provided with an outer sole 8 is attached to the lower surface of the sole parts 2 and 2 *

Of course, the ski boots made according to the invention can with a tongue or · flap of leather or Pell be provided that ^f is below the overlap of the front portions 3 '3 and the belt 5 extends · The ski boot can be used in the prepared embodiment · As Alternatively, it can also be used with a removable inner shoe A, as indicated by dashed lines in FIG there are air bubbles

Investigations have shown that ski boots can be manufactured according to the method according to the invention, which are essentially equivalent in appearance and use to the usual ski boots made of leather are »Of course, the two halves of the ski boot can not only be injection molded, but through Customary compression molding or the like can be produced.
