Definitions

• the present invention relates to a safety shoe with outer metatarsal protection.
• Safety shoes of this type are provided with a steel toe cap, which serves as toe protection or protection for the front area of the foot.
• a steel toe cap which serves as toe protection or protection for the front area of the foot.
• outer metatarsal protection in the case of safety shoes in order to protect the metatarsus against shock or impact loads.
• a hard shell made of plastic, etc. has been arranged on the actual shoe and attached to it.
• such a hard shell has the disadvantage that it is impossible to bend the shoe in the midfoot area. The wearer of the shoe is hereby severely hindered in his movements, in particular working in the kneeled state is only possible with difficulty.
• the object of the invention is to create a safety shoe, the outer metatarsal protection of which, with a good protective effect against impact, impact, etc., enables the wearer to move as freely as possible.
• This object is achieved in a safety shoe with outer metatarsal protection in that the
• Metatarsal protection is designed as a flexible tab having at least two air chamber areas separated from one another by a flat section running transversely to the longitudinal direction of the foot.
• the invention therefore turns away from the solution of the prior art, in which a rigid, possibly hinged, metatarsal protection is used, and instead proposes a flexible metatarsal protector which, on the one hand, offers optimal possibilities of movement for the shoe wearer and on the other hand adequate protection against blows, impacts, etc. is guaranteed.
• This is achieved according to the invention through the use of a flexible tab into which at least two air chamber regions are integrated, which are separated from one another by a flat section which acts as a joint.
• the arrangement of the flat section which acts as a joint allows the shoe to be bent without hindrance by the metatarsal protection, so that the wearer of the shoe can work in a kneeled state.
• the air chamber areas provide sufficient damping of the shock or impact loads and provide adequate protection for the midfoot area located underneath.
• the tab has two flat sections running transversely to the longitudinal direction of the foot, both of which act as joints.
• three air chamber areas are therefore provided, which are separated from one another by the two flat sections.
• the tab preferably has a sheathing and at least one insert made of flexible material, which the
• This embodiment has the advantage that the provided metatarsal protection can be made of the same material as the rest of the shoe, for example leather, while the actual element providing protection, namely the insert, is inside the outer casing arranged and is therefore not recognizable from the outside.
• the casing can be pocket-shaped, into which the insert is inserted.
• the midfoot protection in particular the casing containing the insert, is preferably attached in the area of the toe protection, ie. H. the steel cap. This ensures that there is no unprotected area between the steel cap and the metatarsal guard.
• the fastening itself is preferably carried out by means of suitable rivets, the fastening expediently taking place only in the front region of the metatarsal protection or the casing, in order not to hinder the putting on and taking off of the shoe.
• the individual air chamber areas can be designed as continuous air chambers. A particularly good protective effect against impacts or bumps is achieved if the air chamber regions have a large number of individual ones
• Air chambers included With this division of the areas into a large number of individual air chambers, individual small air volumes are created which, since lateral deflection is only possible to a limited extent with the corresponding impact, only leads to improved stability or strength and thus an increased impact or Lead impact absorption.
• the individual air chambers can be separated from one another or connected to one another via relatively narrow areas.
• the individual air chambers are hemispherical.
• the carrier layer can be designed as a flat film, for example made of rubber, plastic, from which the air chambers, which are in particular hemispherical, extend upwards and downwards.
• Opposite air chambers can be connected to one another by the carrier film. However, they can also be separated from one another by the carrier film.
• the tab contains two inserts with air chamber areas arranged one above the other.
• the two inlays are preferably not fastened to one another, and thus can be moved relative to one another, with the arrangement of the inlays in the casing limiting the lateral displacement. pushability is specified.
• the air chambers of one insert are arranged offset to the air chambers of the other insert in such a way that the air chambers of the two inserts interlock.
• This embodiment also has the advantage that - in spite of the formation of a large number of individual air chambers which are separated from one another by air chamber-free regions - every point on the surface of the tab is ultimately covered by an air chamber, since the air chambers are located in the lower one and complete the upper insert to create a uniform, flat air chamber area.
• This also preferably applies to the flat sections arranged between the air chambers, which act as a joint.
• the upper insert is provided with the flat sections running transversely to the longitudinal direction of the foot, while the lower insert has air chambers over its entire surface.
• a transverse row of air chambers of the lower insert contacts a flat section of the upper insert.
• the two-layer embodiment of the metatarsal protection according to the invention offers a particularly high resistance to shock loads, because the interlocking air chambers of the upper and lower insert achieve a corresponding stabilizing effect.
• the composite effect achieved between adjacent chambers prevents the chambers from evading or being displaced to the side. This results in the desired increased resistance.
• a tab for tying is preferably provided.
• the shoe can be designed in a conventional manner below the tab-shaped metatarsal protection.
• FIG. 1 shows a spatial representation of a safety shoe provided with an outer metatarsal protection
• FIG. 2 shows a top view of the tab forming the metatarsal protection, the individual air chambers being shown,
• Figure 4 is an enlarged view of the details contained in the circle of Figure 3.
• the safety shoe shown in Figure 1 has a shaft 2 and a sole 1.
• a tab 4 serving as a midfoot protector is fastened with the aid of rivets 5 and consists of an outer casing and two inserts arranged one above the other. Both inlays have a large number of air chambers.
• the exact structure of the inserts is shown in the following FIGS. 2 to 4.
• the upper insert has three areas 6 of air chambers which are separated from one another by flat sections 7 running transversely to the longitudinal direction of the foot. These sections form joints.
• the sheathing of the flap 4 consists of the same material as the rest of the shoe, so that there is a uniform appearance.
• the strap 4 is fastened to the shoe with the aid of a strap 8.
• FIGS. 2 to 4 show the exact structure of the tab 4 serving as the middle foot protection. From the longitudinal section in FIG. 3 and the top view in FIG. 2, it can be seen that the flap 4 has an outer casing 16 which is sewn together laterally in a flat edge region, as shown at 17. In the casing there is an upper insert 10 and a lower insert 9, which are arranged one above the other. Both inlays have a flat edge II and a central air chamber area.
• the lower insert 9 has an air chamber area which consists of a plurality of hemispherical air chambers 12 which extend up and down from the plane of the insert. The corresponding hemispherical air chambers 12 are relatively evenly distributed over the entire area of the insert 9.
• the upper insert 10 is essentially congruent with the lower insert 9, but is shorter than this and only extends over approximately 2/3 of the area of the lower insert.
• the air chamber area of the upper insert 10 is in divides four areas 14, which are separated from one another by flat sections 13 running transversely to the longitudinal direction of the shoe. These sections 13 act as joints.
• the air chambers 18 of the upper insert 10 are also hemispherical and extend upwards and downwards from the plane of the insert.
• the two inlays 9, 10 are placed one on top of the other in such a way that the hemispherical air chambers of the upper inlay projecting downward engage in the interstices between the upwardly projecting air chambers 12 of the lower inlay.
• the downwardly projecting air chambers 18 of the upper insert therefore border on four upwardly projecting air chambers 12 of the lower insert and are prevented from evading laterally by them. In this way, a stable connection of the air chambers is achieved.
• the arrangement of the air chambers is such that a transverse row of the upwardly projecting air chambers of the lower insert contacts a flat section 13 of the upper insert, so that the flat areas 13 are also supported by air chambers.
• the air chambers of the lower and upper insert are predominantly hemispherical.
• Elongated, curved air chambers 15 are provided on the edge only in the front region of the upper insert 10.
• FIG. 4 shows the circled detail of FIG. 3. It can be seen that an upper and a lower layer of the casing are sewn together at 17 and with the flat edge 11 of the upper and lower insert 10, 9. In this way, the inserts are fixed in the casing. A hemispherical air chamber 18 protruding downward from the upper one Insert 10 engages between two upwardly projecting hemispherical air chambers 12 of the lower insert 9. When an impact load is applied to the air chamber 18 shown in FIG. 4, the latter tries to expand laterally, but is caused by the adjacent air chambers 12 of the lower insert 9 prevented from doing so, so that there is a stable elastic damping effect.
