Definitions

the invention is directed to a shoe, in particular an occupational safety shoe, with at least one damping element arranged in the heel area.
damping elements In known occupational safety shoes with a damping element, these damping elements essentially consist of plastic blocks inserted into the heel or sole.
a shoe is known in which several cushioning elements are distributed over the heel and are arranged below the insole. A direct introduction of force from the foot into the damping element when it occurs cannot be achieved in this way.
recesses are provided in the heel, which extend parallel to the tread, wherein interchangeable damping elements can be inserted into these recesses.
This basic construction has also been further developed such that the longitudinal recesses extend in two directions perpendicular to one another, in particular in the longitudinal and transverse directions of the shoe, each parallel to the tread.
Sports shoes are known from FR-A-2 535 950, EP-A-0 399 332 and FR-A-2 639 519, the heels of which have recesses which extend more or less through the entire heel in the vertical direction.
the damping elements consist of air chambers or absorption bodies or combinations thereof. The type of attachment of these damping elements and their damping effect is based on the manufacturing technology and the specific load on sports shoes.
the object of the invention is to design a protective work shoe in such a way that such hydraulic damping elements can be installed on the one hand with an optimal damping effect and on the other hand with a manufacturing technique suitable for protective work shoes.
the insole of the shoe has a recess which is slightly larger than the diameter of the base body of the damping element, and that an outsole with heel is foamed on the insole, the flange on the side facing away from the outsole Insole rests and a cover is arranged between the foamed sole or the heel and the damping element.
a preferably hydraulic damping element arranged in this way does not sit positively in the finished heel, but has a radial play, which enables the base body to react elastically to the damping fluid displaced under pressure, to a certain extent in the direction parallel to the running plane.
Such hydraulic damping elements basically consist of two elastic, lamellar disks, between which an oil cell is embedded. When stepping on the heel bone, the oil is pressed between the flexible lamellae, which means that the energy is dissipated smoothly, precisely at the critical moment of the movement. This active participation of the damping system in the shoe is fully guaranteed by the installation according to the invention.
this installation technique enables a very efficient production, in that the damping element is first connected to the insole via its flange, the lower cover also preferably being attached at the same time, in particular being attached by sewing through.
the cushioning element, cover and insole form a preassembled, easy-to-use unit to which the heel and the outsole can be directly foamed.
the cover not only ensures that a space ensuring its functionality remains around the damping element, but at the same time the cover also acts as thermal insulation, which protects such temperature-sensitive hydraulic damping elements against the hot foam during the manufacturing process.
the damping element is preferably arranged such that the flange approximately closes with the rear edge of the insole. This ensures that when running and putting on the heel, which first comes into contact with the ground via the rear edge, there is a central introduction of force into the damping element and thus a particularly advantageous effect of such hydraulic damping elements is ensured.
a shoe 1 shown in the drawing comprises an upper leather 2, an insole 3 with a lining 4, a foamed outsole 5 with an integrated heel 6 and a wear profile 7.
the insole 3 has a recess 8 in the area of the rear edge of the heel 6.
a damping element 9 is inserted into this recess 8 in such a way that a spherical section 10 of the damping element 9 sits in the recess 8 with slight radial play and slightly protrudes beyond the insole 3.
the damping element 9 is composed of two plastic molded elements 11 and 12, which are connected to one another along a circumferential flange 13.
a plastic molded part 14 which is of approximately flat, conical shape and has a plurality of ribs and grooves which extend radially outward from the tip of the cone.
a hydraulic fluid e.g. Oil
Such a damping element 9 is e.g. described in German patent application P 39 06 466.
the flange 13 of the insole 3 bears from below.
the flange 13 is the Insole 3 or lining 4 from above, ie from the inside of shoe 1.
a cover 15 is additionally provided in this embodiment, which extends over the damping element 9 into the area of the insole 3.
the distance s of the actual damping element 9 from the rear edge 16 of the insole 3 is selected so that during normal running, when the paragraph 6 strikes the surface and accordingly a counterforce to the impact force on the paragraph 6 or the foot (arrow F) acts, this force, as illustrated in FIG. 2, is intercepted by the damping element 9.
