Definitions

  • the invention relates to a safety shoe with protective cap according to the preamble of claim 1.
  • Safety shoes are shoes in the form of shoes or boots, which are used as protective clothing. These are prescribed in the industry, in the construction industry as well as in gardening and landscaping, in the fire department, the technical relief organization and in the rescue service. For certain craft professions, such. As in chefs, safety shoes must also be worn.
  • the safety shoe is characterized in that in the front part of the shoe (eg between lining and outer shaft) a protective cap made of steel, aluminum, titanium or plastic is incorporated, which serves to protect the toes.
  • the protective cap usually extends to the toe root and protects the toe area against bruising by heavy objects falling on it.
  • the shoe bottom is often insulated or antistatic and has a puncture-resistant midsole for protection classes S1, P, S3 and S5.
  • the highly profiled outsole usually consists of an acid- and oil-resistant, well-adhering PU, TPU or a rubber compound.
  • the invention is therefore the object of developing a safety shoe according to the preamble of claim 1 so that it can be made much easier, that its production is cheaper and training as a heavy shoe or boots is avoided.
  • the invention is characterized by the technical teaching of claim 1.
  • the novel safety shoe consists of a flexible plastic material whose properties are not in themselves suitable for the production of a safety shoe.
  • plastic materials are highly flexible materials, as z. B. in garden clogs, sandals, galoshes or the like footwear known.
  • an insert part is embedded, which is connected at least from a bendable puncture-resistant structural sole and optionally with the protective cap and / or a rear cap insert.
  • this is understood to mean that an insert, which is inserted at least from a puncture-resistant structural sole in conjunction with a protective cap attached thereto immediately during the production of the plastic shoe in the casting or foaming mold and thus completely encapsulated or foamed by the plastic material.
  • the penetration-resistant textured sole in the bottom of the shoe is embedded (namely, foamed or poured), and because this structural sole is connected according to the invention with the cap, so that at the same time the cap is inserted with the foaming or casting mold and encapsulated or foamed.
  • the two parts protective cap and structural sole form a mechanically suspended part.
  • the essence of the invention is to use an insert consisting at least of a puncture-resistant structural sole, which is connected in the front with a protective cap, as an insert into a foaming or casting mold and to be completely encapsulated by the plastic or optionally as a loose part to insert in a conventional footwear and fix it there.
  • the insert is not limited to the connection of a puncture-resistant structural sole with a protective cap, but it may also be additionally provided that a rear cap insert is connected to the structural sole.
  • the insert is a total of three parts, namely consists of a protective cap which is connected in the front end to the structural sole and also consists of a rear cap insert, which is connected in the rear part of the structural sole.
  • the insert consists only of the structural sole and the rear cap and such a two-part insert can also be glued or foamed in the manner described above in all embodiments in the material of a shoe or loose insert can be integrated into a conventional footwear.
  • galoshes are overshoes that are worn over them to protect the shoes when needed (eg slush). Since they are usually made of rubber, dressing and undressing due to the elastic material is easy. In Europe, they are mainly used by builders, architects, veterinarians, etc., who need to be in a more polluted environment in the short term.
  • the invention now provides that such galoshes can be equipped with the abovementioned features of an insert and thus meet the requirements of safety shoes.
  • Clogs are slippery plastic shoes.
  • Birkenstock introduced clog-like polyurethane (designed for gardening) shoes that were later expanded to include a replaceable footbed to improve wearer comfort.
  • the invention therefore for the first time offers the possibility of inexpensively manufactured footwear, which is not actually suitable for training as a safety shoe, now convert as a safety shoe, but no complex measures are required, as they are relatively necessary in the production of conventional safety shoes.
  • FIG. 1 a structural sole 1 is shown, the structure and properties of which in the same applicant DE 196 41 866 A1 or the EP 1 097 650 B1 extensively described. The description therein is intended to be fully encompassed by the subject matter of the present invention.
  • the structural sole 1 after the FIGS. 1 and 2 preferably consists of a spring steel material, which according to FIG. 2 a corrugated structure 2, which is formed from a series of oppositely directed angle to each other angled bends 3, 4.
  • the mutually angled bends 3, 4 thus form at the bottom transverse grooves 5, according to the embodiment according to FIG. 1 are arranged obliquely to the longitudinal axis of the structural sole 1 parallel to each other and at a mutual distance.
  • recesses 6 are provided in the material of the structural sole, which are preferably formed as holes.
  • recesses 6 serve on the one hand for producing an air passage through the structural sole 1, but on the other hand they also serve as anchoring means for anchoring the plastic material 23, when formed from the structural sole 1 insert 18, 19, 22 in the foaming or casting mold for producing a Safety shoe 40-43 is inserted and the plastic material 23 is fixed in the recesses 6.
  • FIG. 1 shows, moreover, that although the transverse grooves 5 arranged in the heel region are likewise arranged parallel and at a mutual distance from one another, they describe a different angle to the longitudinal axis than the transverse grooves 5 arranged in the front toe and ball region.
  • FIGS. 3 to 5 schematically illustrated flexibility of the structural sole 1 achieved.
  • FIG. 4 shows that an excellent lateral stability is achieved under the action of forces in the arrow directions 8, as well as under the action of forces in the directions of arrows 9
  • FIG. 5 shows that it gives an excellent lateral stability, without causing undesirable deformation of the structural sole 1 under the action of forces in the directions of arrows 9.
  • FIG. 6 shows now that the structural sole 1 according to the invention can be mechanically connected in its front region with a protective cap 10 and here either a connection with a rear cap insert 20 can be done.
  • FIG. 7 shows according to the above combination according to paragraph 1, the combination of a structural sole 1 with a protective cap 10 and an arranged in the heel area Deutschenkappen-insert 20th
  • a slide-in guide is provided, which consists essentially of two mutually parallel legs 15, 16, which have a receiving opening 14 for engaging the structural sole 1 between them.
  • the structural sole 1 is thus received by clamping between the legs 15, 16.
  • additional layer securing means such as. As adhesive joints, welded joints or the like.
  • the same conditions with the same description also apply to the attachment of the rear cap insert 20 in the heel region of the structural sole 1.
  • the rear cap insert shows two mutually parallel legs 25, 26, the one Receiving opening 24 and thus form a slot guide.
  • the structural sole 1 is set in the same manner in the insertion guide.
  • all mechanical connections are claimed as essential to the invention here, such as. As bonding, welding, riveting, screws, clamps or wedging.
  • modified embodiment shows the FIG. 8 in that instead of a slide-in guide with two legs 15, 16 parallel to each other; 25, 26 also only a single leg (eg, the lower leg 16 or 26) may be present and the structural sole 1 is fastened with its underside by not shown fasteners 17 on the legs 16, 26.
  • Such a fastening 17 may, for. Example, a screw, rivet, adhesive joint, welded joint, pin-hole connection and the like.
  • FIG. 7 also shows only schematically the structure of such a protective cap 10, which is preferably made of a plastic material. However, it can also consist of a steel material, a plastic mesh or a cast or injected plastic.
  • the protective cap 10 has a receiving opening 11 suitable for the front toe region, and the front side 13 extending from the upper shell 12 extends forward, which merges into the two mutually parallel legs 15, 16.
  • FIG. 9 shows that in the FIGS. 7 and 8th formed insert 22 may be formed as a simplified two-part insert 18.
  • only one rear cap insert 20 is attached to the heel portion of the structural sole 1 via the previously described connection measures.
  • Such a two-part insert 18 therefore offers in conjunction with the special properties of the structural sole 1 for the first time the possibility that one has limp shoes, such.
  • a safety shoe is realized, which is characterized by a toe-side protective cap.
  • FIG. 7 shows with respect to the rear cap insert 20 only as an example that this has a rear wall 21 which is slightly curved in a conventional manner closes around the heel of the foot to be supported and that this rear wall 21 z. B. in the two mutually parallel legs 25, 26 merges, which form the insertion guide in connection with the receiving opening 24.
  • the rear cap insert 20 is preferably designed as a plastic part, which is produced by injection molding, blow molding or other methods.
  • the material of the rear cap insert can be made of a softer plastic with better wearing properties than comparatively the plastic of the protective cap 10, which should be impact and impact resistant.
  • Hinterkapppen-Einlage 20 is not restrictive for the present property right.
  • the rear cap insert 20 as shown in the drawing FIG. 11 is shown, this may also be formed only as a rear cap, ie it does not necessarily have to be embedded in the plastic material of a shoe by foaming or spraying.
  • the insert 18 after FIG. 9 also provide for insertion into a conventional, existing footwear, whereby this footwear is additionally equipped with the puncture-resistant sideways, but longitudinally flexible structural sole 1 and in addition a heel bed is provided.
  • this footwear is additionally equipped with the puncture-resistant sideways, but longitudinally flexible structural sole 1 and in addition a heel bed is provided.
  • the so-equipped footwear superior wearing properties are assigned.
  • FIG. 10 shows the alternative to FIG. 9 in that the rear cap insert 20 can also be dispensed with and the insertion part 19 thus formed consists only of the protective cap 10, which is connected to the structural sole 1 via a high-strength mechanical connection. Again, there is the possibility of inserting the thus formed insert 19 either in a foaming or casting mold for producing a plastic shoe and to integrate the insert 19 completely in the material of the plastic shoe.
  • the insert 19 is loosely or adhesively inserted into a conventional existing footwear and this footwear is thus designed as a safety shoe.
  • FIG. 11 shows that in FIG. 7 and 8th illustrated insert 22 is now completely embedded in the plastic material of a safety shoe 40 by foaming or injection molding. It has already been pointed out that the integration of the insert 22 is shown only by way of example. Just as well can the inserts 18 or 19 in the structure according to FIG. 11 be integrated.
  • the safety shoe 40 thus produced consists essentially of a plastic material 23, which forms the shaft 27, which merges forward into a toe cap 28, to which the outsole 29 is injection-molded in one piece.
  • the z. B. is designed as a clog, now the insert 22 is integrated by full enclosure with the plastic material 23.
  • the protective cap 10 and the rear cap insert 20 are mechanically fixedly connected to the structural sole 1, so that the safety strap 10 (eg in training as garden clog), which in itself is limp or highly flexible, is now assigned superior safety features become.
  • the protective cap 10 protects the toes against mechanical damage from the front, the structural sole 1 is resistant to penetration and gives superior wearing properties due to its longitudinal flexibility and transverse stability and the heel insert 20 connected in the heel area to the structural sole 1 forms a heel bed, whereby superior wearing properties are achieved.
  • FIG. 12 shows, however, the retrofitting of a conventional work shoe 41 with an insert 18 after FIG. 9 ,
  • the retrofitting could also be done with an insert 22 or an insert 18.
  • the work shoe 41 is formed as a twilled shoe whose shaft 31 consists of a plastic material or a leather material, wherein the shaft 31 merges into the front cap 32 on the front side and an outsole 36 is sewn or glued in the creasing region 33.
  • the outsole 36 has a profile 37.
  • the insole of such a work shoe 41 is formed by an insert 18 or 19 or 22, and on the underside of the insert 18, 19, 22 a ball mass 34 is arranged in a known manner, which the level balance at the bottom of Work shoe 41 for gluing or sewing the outsole 36 forms.
  • the shoe may have a rear cap 30 formed from the material of the shaft 31.
  • the rear cap 30 is omitted and instead only the rear wall 21 of the rear cap insert 20 is present.
  • the rear cap insert 20 may be omitted and instead only the rear cap 30 of the shoe may be present.
  • the rear wall 21 and the rear cap 30 may be connected to a single part.
  • FIG. 12 does not show that a conventional work shoe with a conventional insole and a conventional outsole can also be retrofitted as a safety shoe in which loosely or glued into the interior of this work shoe 41, the previously described inserts 18 or 19 or 22 are inserted and fixed there.
  • the said inserts 18, 19, 22 can then be covered on the top side by an insole 35.
  • this is also claimed as essential to the invention.
  • FIG. 13 shows a further embodiment of a safety shoe 42, in which only the underside of the structural sole 1 and thus of the insert 18, 19, 22 is molded from the plastic material 23, while the structural sole 1 in the direction of the interior of the safety shoe 42 thus formed is "naked" ,
  • an insole 35 can be placed on the surface of the structural sole 1 .
  • the insert 18, 19, 22 is completely enclosed by the plastic material 23 of the safety shoe 42. It is also sufficient, an external gating or foaming on the surfaces of the inserts 18, 19,22.
  • FIG. 14 a further embodiment of a safety shoe 43 is shown, in which - about the same as in the description of FIG. 11 -
  • the insert 19 is completely integrated and molded in the plastic material 23 of the plastic of the safety shoe 43.
  • a conventional, inexpensive to produce plastic shoe is converted as a safety shoe, in which with the longitudinally flexible, but highly stable structural sole a protective cap is connected and it is thereby possible for the first time to produce such a safety shoe 43 at a particularly low manufacturing cost and high safety.
  • the shoe-side rear cap 30 is omitted and the thus formed safety shoe 43 is formed as a sandal.
  • heel straps or the like are provided for holding the heel.
