Description

The invention relates to a shoe, in particular a sports shoe, which has a shoe upper and a sole connected to the shoe upper, wherein the shoe upper has in its instep area two adjacently disposed and separated by a gap clamping portions, wherein a lacing system is present, with which the shoe on Foot of the wearer of the shoe can be laced by the adjacently arranged clamping portions are pulled towards each other, wherein the lacing system comprises a central closure, with which a first clamping element can be stretched.

Such a sports shoe with a central closure (screw cap) is for example from the DE 297 01 491 U1 known. The central or rotary closure allows the tension of the clamping element (Schnürfaden or wire) by turning the knob with low torque to produce a sufficiently high clamping force and thus to lace the shoe. In this case, for a uniform as possible application of the lacing force on the foot of the wearer of the favorable distribution of tension or lacing force is of great importance. This is especially true in sports applications, such as running, where it is therefore desirable to transmit the tension - caused by the tensioned tension wire - as evenly as possible on the foot of the wearer. Similar and others Solutions reveal that EP 1 795 085 A1 , the GB 214 719 A , the WO 99/37176 A1 , the US 5 791 021 A and the US 2003/204970 A1 ,

Previously known sports shoes are sometimes disadvantageous in this respect, because the tightening tension is distributed only to partial areas of the surface of the shoe upper, thus resulting in an overall not uniform distribution of the tension forces.

It is still not possible with known laces, targeted to lace certain areas of the foot. Again, it is therefore particularly disadvantageous in sports use that the forefoot can not be laced targeted.

The invention has for its object to develop a generic shoe so that an improved tension of the shoe at the foot of the wearer is achieved. In particular, the tensioning cable, which is produced by strapping the shoe by means of a central closure, should spread more evenly over the foot of the wearer. This should also improve the grip of the shoe on the foot of the user. Furthermore, it should be achieved that also the forefoot can be laced as such targeted.

The solution of this object by the invention is characterized in that at least one Zugübertragungselement is present, which comprises a first, preferably upper tension member and a second, preferably lower tension member, wherein the first clamping element engages in the first tension member and it during tightening of the first clamping element pulls in the direction of the instep area, wherein a second tensioning element is provided, which is fastened with its two ends to the sole or in a lower region of the shoe upper, wherein the second tensioning element engages in the second tension member and during clamping of the first tensioning element in the direction of Sole pulls, wherein the first tensile member and the second tensile member are interconnected via a tension member.

The tension element can be fastened with its one end to one of the two tension members, preferably on the second tension member, wherein the tension member passes through an opening, in particular through an eyelet on the other tension member, preferably on the first tensile member, and wherein the tension member with his other end is attached to the shoe upper. As a result, a power transmission effect can be achieved in a simple manner by using the principle of the pulley. The tension element is preferably formed as a band whose thickness is at most 20% of its width.

The central closure is preferably arranged on a tongue in the instep area of the shoe. The tongue is arranged under the gap, which separates the clamping sections from each other.

Arcuate guides for the first or second clamping element can be arranged in the pulling parts. The first tensile member preferably has a single arcuate guide for the first clamping element. However, according to an alternative solution, it can also be provided that the second pulling part has two curved guides for a second clamping element or two second clamping elements.

According to a further development, the second tensioning element is guided through at least one sole eyelet and is deflected by the latter, wherein the sole eyelet is arranged, ie fastened, on the sole or in a lower region of the shoe upper.

The second clamping element can be guided by a heel eyelet arranged in the heel region of the shoe. In this case, the second tensioning element preferably runs at least in sections between the second tension part and the heel eyelet in the interior of the shoe upper part or along the inside of the shoe upper part.

The first tensioning element can run through a plurality of first tensioning parts, which are arranged on both sides of the instep area. In this case, provision is made in particular for the first tensioning element to run on or on a tensioning section between two first tensioning parts through a guide element which is connected to the tensioning section.

A concrete embodiment of the proposed shoe provides that two Zugübertragungselemente are arranged on each side of the shoe upper.

The first clamping element or the second clamping element may consist of a wire of high-tensile material, in particular of aramid (brand name, among others KEVLAR). The first tensile member and the second tensile member are preferably made of a plastic, wherein at least one arcuate guide is preferably introduced by an injection molding process.

The proposed shoe is particularly preferably designed as a sports shoe, in particular as a running shoe.

The Zugübertragungselemente with engaging in these first, but especially second clamping elements are preferably over a significant part of the surface of the shoe upper in the fore, Metatarsal and Heel area arranged distributed. The hold of the shoe at the foot of the wearer can thus be optimized. At the same time, stress concentrations (so-called irritation points) can be reduced.

The second clamping elements can be guided so that they do not extend over the metatarsal heads of the metatarsals, whereby a natural and comfortable tension of the shoe can be ensured at the foot of the wearer.

The invention accordingly provides a lacing or tensioning system for a shoe, in particular for a sports shoe, in which a simple tightening or lacing of the shoe is possible by means of a rotary or central closure. In this case, a favorable stress distribution is achieved by the guidance of the clamping elements (especially the second clamping elements), wherein the second clamping elements are preferably fastened in the sole region and extend upwards to the Zugübertragungselementen.

A special development of the invention is based on the fact that the two shoes for the right and left foot are not mirror-symmetrical, but asymmetrical. Hereby, special requirements for some sports can be taken into account. When using the proposed shoe in golf, a lateral support function by the tension elements is desirable to counteract the forces occurring during the rotation of the foot during the golf swing. In this case, the right and the left shoe can be formed differently with respect to the course of the clamping elements in order to achieve the said effect.

With the proposed embodiment, an improved tension or lacing of the shoe is achieved at the foot of the wearer. There is a surface and distributed over large parts of the shoe upper tension or lacing, resulting in a more uniform distribution of the tensioning cable. In that regard, a clamping system is proposed, in which results by the provided tensile transfer elements and (second) clamping elements, a homogenization of the clamping forces on the foot surface. The thus improved grip of the shoe at the foot of the wearer is particularly useful in sports.

The second clamping elements are - as explained - fixed to the sole or in the area between the shoe upper and sole. But this is also to be understood that the fixation point (anchor point) is not exactly at the transition between the shoe upper and sole; it is also possible that the anchor point is slightly above the sole on the shoe upper; on the other hand, the anchor point may also be lower than the transition point from the shoe upper to the sole.

In the drawing, an embodiment of the invention is shown. Show it:

an enlarged section of the side view Fig. 1 ,

In the figures, a shoe 1 can be seen, which is designed as a sports shoe. The shoe 1 has in a known manner a shoe upper 2 and a sole 3, which is attached to the bottom of the shoe upper 2. For tensioning or lacing the Shoe 1 at the foot of the wearer are two tensioning sections 5 (only one of which is visible) in the instep area 4 of the shoe, which form a gap between them; the clamping sections 5 are pulled towards each other when lacing the shoe. Below the gap, a tongue 16 is arranged in a known manner, which has a padding on its underside.

For clamping or lacing itself a central closure (screw cap) 6 is used, which is arranged on the tongue 16. With the central closure, a first clamping element (tension wire) 7 is tensioned. The central closure 6 and the first clamping element 7 are thus part of a lacing system that serves to lace the shoe 1.

It is essential that a number of Zugübertragungselemente 8 are provided, in the present case two on each side of the shoe 1. Each Zugübertragungselement 8 has a first, upper tension member 9 and a second, lower tension member 10. The already mentioned first clamping element 7, that of the central closure 6 is tensioned, engages in the first tension member 9, in an arcuate guide 22 (s. Fig. 2 ) of the same. When tightening or lacing the shoe, the first tensile member 9 is thus pulled by the first clamping element 7 in the direction of the instep area 4 (high).

Furthermore, a plurality of second clamping elements 11 are present. These are attached with their respective ends 12 and 13 to the sole 3. Each of the second clamping elements 11 engages in the second tension member 10 and pulls it during tightening or lacing of the shoe down, ie in the direction of the sole 2. In the second tension member 10 also arcuate guide 23 are incorporated (s. Fig. 2 ), through the respective second clamping elements 11 lead.

The first tensile member 9 and the second tensile member 10 are connected to each other via a tension member 14. The tension element 14 is designed as a tension band and has a width B (s. Fig. 2 ), which is substantially larger than the thickness of the tension element 14. The tension element 14 is guided by an eyelet 15 in the first tension part 9. With its one end, the tension member 14 is connected to the second tension member 10 (this can be done in situ during injection molding of the second tension member 10 by inserting the tension member 14 in the injection mold). With its other end, the tension element 14 is connected to the shoe upper 2; it is sewn here, for example.

As in Fig. 1 can be seen for the forward train transmission element 8, here two second clamping elements 11 are present, which are guided by the arcuate guides 23 and secured to the upper end of the sole 3. The tensioning cable when lacing is thus distributed over a relatively large area.

On the other hand, in Fig. 1 be seen on the example of the rear train transmission element 8, that only a single second clamping element 11 is provided here, although it is also guided by two arcuate guides 23 in the second tension member 10; However, here are two sole eyelets 17 and 18 fixed to the sole 3, through which the second clamping element 11 is guided. The result is the leadership of the second clamping element 11, as in Fig. 1 to see.

Another particularity in the guidance of the second clamping element 11 of the rear (right) Zugübertragungselements 8 is the following: The right spout of the second clamping element 11 from the second tension member 10 leads along the foot opening in the heel region 19 of the shoe 1 and here to a heel 20th From the heel 20 from the second clamping element leads 11 then down to the sole. This in turn ensures that the lacing or tightening tension is distributed over a relatively large area onto the surface of the shoe upper 2. In this case, the second clamping element 11 extends partially inside the shoe upper along; For this purpose, openings 24 and 25 are provided, through which the second clamping element 11 from the outside inwards (opening 24) or from the inside to the outside (opening 25) passes.

The first tensioning element 7, which is tensioned directly by the central closure 6, extends through two first tensioning parts 9 which belong to the two tension transmission elements 8. However, between the two tension transmission elements 8 and second tension parts 9, a guide element 21 is fastened in the tensioning section 5, in which the first tensioning element 7 is guided by a corresponding arcuate guide.
