Description

The invention relates to assembled safety shoes, certified according to DIN EN 344 to 346, with certified orthopedic preparations according to the Preamble of claim 1. It relates to a method for producing such certified ready-made safety shoes with certified orthopedic Finishes.

An EC type examination is required for personal protective equipment of categories II and III compulsory. This test according to DIN EN 344 - 346 is carried out by an approved testing institute. If successful Upon completion of the test, the personal protective equipment becomes an EC type examination certificate granted.

1. Bereitstellung der technischen Unterlagen gemäß Anhang III der EG-Richtlinien 89/686 (EWG).

2. Durchführung einer EG-Baumusterprüfung bei einem Prüfinstitut. Diesem muß eine angemessene Anzahl von Schuhen als Prüfmuster vorgelegt werden, üblicherweise 12 bis 15 Paar. Das Prüfinstitut untersucht und prüft die Prüfmuster dahingehend, ob die grundlegenden Anforderungen der EG-Richtlinie 89/686 (EWG) erfüllt sind; dabei werden die Prüfmuster regelmäßig zerstört. Bei positivem Prüfergebnis wird eine EG-Baumusterprüfbescheinigung ausgestellt. Gleichzeitig muß der Schuhhersteller erklären, daß er nur Schuhe herstellen und in den Verkehr bringen wird, die identisch sind mit den Prüfmustern. Auf diese Schuhe kann der Hersteller dann auch das CE-Zeichen aufbringen.

The procedure for an EC type examination for shoes comprises the following stages:

1. Provision of the technical documents in accordance with Annex III of the EC Directives 89/686 (EEC).

2. Carrying out an EC type examination at a test institute. A suitable number of shoes must be submitted to the test sample, usually 12 to 15 pairs. The test institute examines and tests the test samples to determine whether the basic requirements of EC Directive 89/686 (EEC) are met; the test samples are destroyed regularly. If the test result is positive, an EC type examination certificate is issued. At the same time, the shoe manufacturer must declare that he will only produce and market shoes that are identical to the test samples. The manufacturer can then apply the CE mark to these shoes.

Any change in processes and materials compared to the The test certificate cancels the certification.

The EC type examination procedure described above is also up Use safety shoes with orthopedic dressing. at custom-made orthopedic footwear, however, is made to order, adapted to the patient's sick feet. As for the EC type examination The cost for a pair would be 12 to 15 test shoes Orthopedic protective shoes, certified according to EN 344 - 346, priceless high.

In the article "Safety shoe is just beginning", printed in the DE magazine "Orthopedic Shoe Technology", 4/2001, pages 16 and 17 is from competent representatives of the German orthopedic shoemaker craft outlined what problems when applying orthopedic dressings on safety shoes. This article shows that the The starting object must always be an orthopedic safety shoe, one Type test, i.e. a made-up safety shoe from the ongoing production. After the orthopedic shoemaker on this Had made changes, he had to check whether through his work safety-relevant requirements for the specific workplace of the patient are touched. With such a test, which is normally done by the accredited test centers, the orthopedic shoemaker is in generally overwhelmed. The advice given in this article, the Orthopedic shoemaker should contact the patient's employer, who Professional association, the company doctor and the company Contact a security practitioner to determine if he is the operator orthopedically modified and therefore no longer showing a certificate on respective workplace of the patient is still permissible because of this connected time expenditure and that to be taken over by all participants Responsibility is not practicable. The ultima ratio is therefore in this article suggested that the patient change jobs. This Situation is unsatisfactory.

After all, the above article strongly advises against one Safety shoe to cut off the sole because of the risk of damage of the shoe and a resulting loss of strength and Stability are too great. Thus, at best, orthopedic Dressings such as insoles or footbeds can be used. That too is unsatisfactory.

The present invention is therefore based on the object of safety shoes for the orthopedic care of less severely ill feet, the certified according to DIN EN 344 - 346 and still affordable.

This task is solved by a safety shoe with the characteristics of Claim 1.

The present invention makes use of the fact that the Type examination according to DIN EN 344 - 346 not only the 12 to 15 complete Shoes but also all shoe parts are checked individually by the steel toe over the insole, the outsole to the upper. By using it a prefabricated partial shoe and the associated outsole from the ongoing production of certified, assembled safety shoes is no longer required Type examination for these parts. All that remains is the need for that materials used for the manufacture of orthopedic dressings and of course to have the finished shoe made from it checked. This Exams for which 10 to 15 pairs of shoes must be provided however only be done once. This is done by the System supplier of the orthopedic shoemaker.

The main advantage of the present invention is that the Shoe rack can be sure that even after installing the orthopedic A certified safety shoe that complies with the applicable regulations Security standards and thus the highest possible security and the guaranteed the best possible accident protection. The orthopedic shoemaker in turn, can be sure that he is a fully orthopedic Safety shoe produced, the certificate of which is valid, so that it does not have to fear liability problems. It is natural Prerequisite that he only uses the tools and working methods in his work applies, which are part of the EC type examination certificate.

The term “orthopedic dressings” means the present invention Sole rolls, heels, solder structures etc., d. H. everything from the Midsole according to the invention can be produced.

According to an advantageous embodiment of the invention Midsole made of a material compatible with the outsole. this fact On the one hand, it makes certification easier because the outsole and the compatible one Construction material itself is already certified, and simplifies completion of the safety shoe after making the orthopedic dressings because it cannot give compatibility problems.

On the one hand, assembled safety shoes have according to their Purpose, but also to achieve the necessary Strengths a particularly stable insole. This makes safety shoes usually for patients with sensitive feet like them for example, widespread among diabetics, almost intolerable. Around Here To remedy the problem, get the insole and midsole on the orthopedic indicated places a recess in which a suitable cushion layer is inserted. This will remove the sensitive areas of the patient's foot particularly softly supported. The shoe still has its certification.

If the cushioning layer is needed in the area of the forefoot, the Production of the recess also the antistatic contact always provided there be eliminated. To restore the anti-static equipment, located according to a development of the invention in the recess or in at least part of it an antistatically active layer. This represents the electrical connection between the foot of the shoe wearer and the Midsole forth.

According to an advantageous embodiment of the invention, the antistatic is active Layer a mixture of an antistatic, after curing permanently elastic adhesive with cork granulate. Usually, the side surface of the midsole or from the Orthopedic dressings worked out by the midsole Laminated edge of the outsole. With a particularly thick midsole however, part of the side surface would remain visible. To remedy this create, according to a development of the invention, the side surface of the Midsole with a glued tape made of antistatic active material, preferably made of antistatic rubber. In the simplest case, a uniform plate is made from the Sole material or a compatible material used.

According to a further development, the midsole consists of at least two panels. These can have the same properties. Preferably however, they have different properties, so the orthopedic Preparations can be made from the most suitable material.

Another object of the present invention is to provide a method for Manufacture of ready-made certified safety shoes with certified Specify orthopedic dressings, the process being simple, quick and should be inexpensive without the safety certificate any compromises need to be made.

This object is achieved by a method with the features of the claim 11th

The main advantage of this procedure is that the orthopedic shoemaker only have to rely on working techniques familiar to him and that Damage to the used when performing the procedure Materials that reduce the strength and thus expire Result in certificates are excluded.

According to an advantageous development of the method according to the invention a cut out of the insole and the midsole or punched, into which an orthopedically effective cushion layer is then placed is used. It can be used to manufacture safety shoes that are also suitable for feet with discomfort are suitable, for example, for diabetics. So far for this purpose soft insoles must be put in the shoes what However, it had to be rejected for two reasons: First, insoles the space between the toes and the steel cap is inadmissibly reduced and on the other hand there is the electrically conductive contact between the foot and the sole of the shoe interrupted.

If the cut-out is needed for a tread pad at the point where If the standard antistatic contact is seated, the electrically conductive contact must between the foot and sole can be subsequently restored. To this Purpose is in the previously made recess next to the upholstery material an antistatically active and also soft layer is used, preferably a permanently elastic hardening mixture of cork granulate with antistatic active and certified adhesive.

To high side surfaces of the midsole or the one made from it To be able to board orthopedic dressings, is before Attach the outsole using the anti-static, certified Glue a tape made of an antistatic active material.

To produce various types of orthopedic dressings on a shoe To be able to, the midsole from at least two plate-shaped parts with different properties.
