Technical Field

The invention relates to an incentive safety shoe.

Background

Safety or anti-injury shoes are known in the prior art, which are able to provide a high degree of protection for the user in the event of an accident.

In order to be able to be defined as being injury-proof, such footwear must comply with strict standards. At present, such shoes must comply with standards EN ISO20344 and EN ISO 20345.

As is known, in order to comply with the current standards in the field, all safety shoes comprise an upper provided at the toe with a safety toe cap sufficiently structured and therefore rigid to withstand impacts and compressions, thus protecting the user's foot.

Since they relate to work shoes, they are not only intended to be worn by a user for many hours per day, but also during activities in which the user is continuously moving.

Therefore, there is a need for the safety shoe in question to be able to ensure a satisfactory level of comfort for the user as well.

To this end, it is known in the prior art to provide a safety shoe equipped with a layered sole comprising an insert made of elastic material which makes it possible to make the stepping on the floor more comfortable during walking.

More specifically, safety shoes are known, for example, in the prior art, which comprise a sole equipped with an elastic insert that extends substantially over the entire sole of the foot of the user. Such resilient inserts are provided to provide soft and dynamic impact absorption that returns energy during walking.

While such anti-injury shoes have been very successful for users and are currently very popular, they are not without their drawbacks.

Disclosure of Invention

The main task of the present invention therefore consists of making a safety shoe which solves the above technical problems and which avoids the drawbacks and overcomes the limitations of the prior art, making it possible to ensure complete comfort for the user while maintaining a satisfactory appearance.

In this task, therefore, the object of the present invention is to make a safety shoe that is absolutely comfortable to walk.

A further object of the invention consists in making a safety shoe which ensures maximum reliability and safety in use.

Another object of the invention consists in making a safety shoe that is easy to manufacture and economically competitive if compared with the prior art.

The aforementioned task, as well as the objects and others that will become clearer below, are achieved by an incentive safety shoe according to claim 1.

Further characteristics are foreseen in the dependent claims.

Drawings

Further characteristics and advantages will become clear from the description of a preferred but not exclusive embodiment of an energizing safety shoe according to the invention, which is shown as an example and not for the purpose of limitation by means of the attached drawings, in which:

FIG. 1 is an overall side elevational view of an energized safety shoe according to the invention;

fig. 2 is an exploded side view of the safety shoe of fig. 1.

Detailed Description

With reference to the cited figures, a safety shoe according to the invention, designated as a whole by the reference numeral 1, comprises an upper 2 equipped with a safety toe cap 4 at the toe and a layered sole 3 associated with said upper 2. The layered sole 3 comprises a lower layer 5 adapted to be in contact with the ground, a middle layer 6 associated with the upper 2 and the lower layer 5, respectively, and an upper layer 9.

According to the invention, an elastic insert 7 is embedded in the intermediate layer 6, which extends only on a surface of less than 55% of the total surface of the layered sole 3 in the rear region of the shoe 1, wherein the upper layer 9 completely overlaps the elastic insert 7.

Basically, the layered sole 3 has no elastic insert, except in the heel region where the elastic insert 5 is present.

The elastic insert 7 is advantageously made of foamed thermoplastic polyurethane.

Preferably, the elastic insert 7 is made entirely of foamed thermoplastic polyurethane.

Advantageously, the elastic insert 7 extends over a surface comprised between 30% and 50% of the total surface of the layered sole 3.

In particular, the elastic insert 7 has a length at most equal to 55% of the total length of the layered sole 3 and a width slightly smaller, if not substantially equal, to the total width of the layered sole 3. Preferably, the elastic insert 7 has a length comprised between 30% and 50% of the overall length of the layered sole 3.

Advantageously, in the front region, the layered sole 3 is constituted only by the superposition of the lower layer 5, of the intermediate layer 6 and of the upper layer 9.

Basically, in the front region of the shoe 1, the layered sole 3 is advantageously free of any type of insert.

Advantageously, the maximum thickness of the elastic insert 7 is less than 21 mm.

The maximum thickness of the insert 7 is in fact advantageously comprised between 18 and 21 mm, depending on the dimensions of the footwear 1, and therefore on its size. For example, for a shoe 1 sized between 35 and 37 French points (French points), the maximum thickness of the insert 7 is about 18 mm, whereas for a shoe 1 sized between 45 and 48 French points, the maximum thickness of the insert is about 21 mm.

Advantageously, the layered sole 3 has a thickness in the front region that is substantially smaller than the thickness of the layered sole 3 in the rear region.

In this way, a slight level difference is formed between the heel and the forefoot of the user, which makes the shoe 1 more comfortable, especially during walking.

In addition, the fact that the thickness of the layered sole 3 is smaller at the front region of the shoe 1 than at the rear region makes the shoe 1 more streamlined, making it more aesthetically pleasing.

Advantageously, the thickness of the layered sole 3 at the front region of the shoe 1 is at most equal to 65% of the thickness of the layered sole 3 at the rear region of the shoe 1.

Advantageously, the maximum thickness of the layered sole 3 is less than 55 mm.

This maximum thickness of 55 mm of the layered sole 3 is reached at the heel of the user, in the rear region of the shoe 1.

On the other hand, the maximum thickness of the layered sole 3 at the front region of the shoe 1 (i.e. at the forefoot of the user) is less than 35 mm.

The lower layer 5 is preferably made of a polyurethane or nitrile material or a combination of these two components.

The intermediate layer 6 is preferably also made of a polyurethane material.

According to a preferred embodiment of the stimulating safety shoe according to the present invention, the upper layer 9 covering said elastic insert 7 preferably comprises a puncture-proof sheet.

Advantageously, said anti-piercing tabs extend so as to completely cover and protect the sole of the user's foot when wearing the shoe.

The anti-puncture sheet is preferably made of a non-metallic material, such as a polyester resin-based material or the like.

The upper layer 9 may be defined by the same material from which the intermediate layer 6 is made. In this way, the elastic insert 7 is completely embedded in the material from which the intermediate layer 6 and the upper layer 9 are made, except for the portion facing the window 12. The energized safety shoe according to the invention includes a safety toe cap 4 in the front region of the upper 2 that meets current safety standards, including EN ISO20344 and EN ISO 20345.

According to the solution developed by the applicant, the shoe 1 according to the invention is advantageously equipped with a safety toe cap 4 equipped with a hole configured to ensure the evaporation of the foot, although the minimum requirement to meet the requirements established by the standards is simply the presence of the safety toe cap 4.

In addition, a protective membrane 11 is preferably provided to close the hole made in the toe cap 4, so as to allow both evaporation and protection of the user's foot.

According to a preferred embodiment of the shoe, one or more windows 12 can be provided on the lateral surface of the intermediate layer 6, so as to make visible the elastic inserts 7 arranged inside the intermediate layer 6 itself, while at the same time they also perform the technical function of allowing the outward deformation of the elastic material making such elastic inserts 7, so as to assist the deformation of the material after compression, increasing the capacity of deformation, the elasticity absorbing the forces generated by the user's weight during walking behaviour.

It has thus been seen how the motivation safety shoe, object of the present invention as described herein, makes it possible to perform tasks and achieve its design objectives.

In particular, the active safety footwear of the present invention is intended to be comfortable to wear, easy to use, and aesthetically pleasing.

Due to the fact that the incentive safety shoe object of the present invention has a thinner sole, the incentive safety shoe object of the present invention is generally more aesthetically pleasing, streamlined and lightweight to the extent that it looks more aesthetically like an athletic shoe than a safety shoe.

It should be understood that the embodiment described as an example may be subject to numerous modifications and variations, all of which are covered by the present invention; moreover, all the details may be replaced with technically equivalent elements.

In particular, the materials used, as well as the dimensions, may be any according to the technical requirements.
