Safety shoe with puncture-proof insert

The innovation concerns a safety shoe with one between the Outsole and the insole arranged-penetration-proof insert, preferably made of sheet steel, from the heel area reaches to the tip of the shoe.

Eb is known to use such an insert by means of its entire Area of distributed nails or the like that penetrate the insert to be attached to the insole before the Outsole is attached.

It is also known to glue the insert to the insole to be fixed permanently.

OiBBB types of fastenings between the insert and the insole lead to an ar. not aimed at reduction the flexibility of the entire footwear.

But if you omit a connection between the insole and of the deposit, the deposit may be a result of more or less Large bite loads when using the shoe migrate between the insole and the outsole and practice with the rslativ

sharp edges from cutting effects that can lead to the insole is removed from the shoe substructure.

The task of the innovation is now to introduce a safety shoe of the type described both in terms of its flexibility and to improve its durability and penetration resistance.

The solution to this problem is characterized according to the innovation that the insert in the heel area is firmly connected to the insole, and that at a distance from this! Fastening point on the insole at least one strip is attached, the end parts of which are bent over the insole laterally in sufficient overlying on the underside of the insert, preferably also the strip, preferably made of sheet metal, in the ball bziu. The tip area of the insole is arranged.

Through these measures, the deposit is on the one hand ζωischen the and the insole are stored in a hitherto unachieved secure manner, on the other hand there are relative movements between the insert and the Shoe substructure possible, resulting in a previously unattained flexibility of the shoe results.

It has been found to be advantageous if the strip is made of sheet metal, preferably sheet steel.

An advantageous and inventive embodiment of the above-described object is characterized by a strip with more than two plastically inflexible end parts.

As a result, the insert is attached to more than one piece by means of a strip Make sure to be fixed.

Furthermore, an advantageous feature is characterized in that openings are arranged in the end parts of the strips.

Through these measures, material can be used when vulcanizing the outsole the same penetrate into the strip openings, so that the Strip end parts are now also secured in a form-fitting manner against unintentional bending.

For this purpose, a variant preferred under certain circumstances is characterized in that the end parts of the strips can engage in the outsole Have Uoraprungβ.

Embodiments of the innovation are shown in the drawings and are described in more detail below.

The figures show: FIG. 1 a shoe lower structure, seen from below, without

Outsole,

In Fig. 1 is attached to the insole 1 of the SchuhuierkunterbauBB Bin interlocking strip 2 made of sheet steel, the end parts 3 of which are bent around the longitudinal edges of a penetration-resistant insert U made of sheet steel so that they lie flat on the underside of the insert. In the end parts 3 perforations 5 are arranged, into which Sahisnmaterial penetrates when the rubber outsole is vulcanized. In the heel area, the insert k is still attached to the insole 1 by means of a nail 6 penetrating the insert.

Also in the Flg. Haltestrsifbn shown in k + 5 is three

In Figs. 6 + 7, a retaining strip Z is cut with four End parts 3 shown. All these strips 2 still have holes 7 for the implementation of

fastening means not shown.

The retaining strips 2 can under certain circumstances also on the Zωickrand of the Schuhtiierks are attached. In order to avoid corrosion, it is beneficial to remove the strips

and the fasteners, such as nails, are made of stainless steel to manufacture.
