The clamping elements are preferably tension wires. You can have polyamide or consist of this material.
Ein wesentlicher Aspekt der vorliegenden Erfindung besteht folglich darin, ein besonders kompakt aufgebautes Getriebe vorzusehen, das es ermöglicht, auf dem Rist des Schuhs angeordnet zu werden und den Drehverschluss des Schuhs zu betätigen. Dabei wird ein hinreichend hohes Drehmoment aufgebaut, um eine effektive Schnüren des Schuhs vornehmen zu können. Das vorgeschlagene Getriebe ist mehrstufig aufgebaut und erlaubt es daher, einen Elektromotor einzusetzen, der ein relativ geringes Drehmoment erzeugt, der indes mit einer hohen Drehzahl (beispielsweise mit einer Drehzahl von 20.000 min"1) arbeitet. An essential aspect of the present invention is therefore to provide a particularly compact gear that makes it possible to be placed on the instep of the shoe and to operate the screw cap of the shoe. In this case, a sufficiently high torque is built up to make an effective lacing the shoe can. The proposed transmission is multi-stage and therefore allows to use an electric motor that generates a relatively low torque, but at a high speed (for example, with a speed of 20,000 min "1 ) works.
Oberhalb des Getriebes können auch entsprechende Schalter für die Betätigung des Drehverschlusses angeordnet sein, beispielsweise ein Schalter für das Öffnen und ein Schalter für das Schließen des Drehverschlusses. Die Schalter können als Druckknöpfe ausgebildet sein. Above the transmission and corresponding switches for the operation of the rotary closure can be arranged, for example, a switch for opening and a switch for closing the rotary closure. The switches can be designed as push buttons.
Die Batterie kann in einer Zwischensohle des Schuhs angeordnet sein. Die für das Aufladen benötigte Elektronik kann direkt an der Batterie platziert sein. Durch das Vorsehen einer Induktionsspule kann die Batterie des Schuhs kontaktlos aufgeladen werden. Hierzu kann der Schuh auf einer entsprechenden Ladeplatte platziert und so die Batterie aufgeladen werden. Vorgesehen werden kann auch eine Steuerung des Drehverschlusses auf drahtlose Weise per Bluetooth über ein Smartphone, das mit einer entsprechenden App versehen ist. The battery may be located in a midsole of the shoe. The electronics needed for charging can be placed directly on the battery. By providing an induction coil, the battery of the shoe can be charged without contact. For this purpose, the shoe can be placed on a corresponding pallet and so charged the battery. Can also be provided a control of the rotary closure wirelessly via Bluetooth via a smartphone, which is provided with a corresponding App.
Der Drehverschluss weist - wie oben erläutert - bevorzugt zwei separate Spanndrähte auf, einen für den lateralen Bereich und einen für den medialen Bereich des Schuhs. Der hiermit erreichbare Effekt besteht darin, dass beim Spannen des Schuhs die Sohle insbesondere im Gelenkbereich nach oben gezogen wird („Sandwich-Effekt"); gleichermaßen wird die Ferse nach vorne gezogen. Hierdurch kann vorteilhaft die Schnürung verbessert werden. In der Zeichnung ist ein Ausfuhrungsbeispiel der Erfindung dargestellt. Es zeigen: The rotary closure has - as explained above - preferably two separate tension wires, one for the lateral area and one for the medial area of the shoe. The effect that can be achieved here is that when the shoe is tightened, the sole is pulled upwards, particularly in the area of the joint ("sandwich effect"), and the heel is likewise pulled forward, which can advantageously improve the lacing. In the drawing, an embodiment of the invention is shown. Show it:

In Figur 1 ist ein Schuh 1 in Form eines Sportschuhs zu sehen, der ein Schuhoberteil 2 und eine Sohle 32 aufweist. Die laterale Seite L des Schuhs 1 bzw. des Schuhoberteils 2 ist in der dargestellten Seitenansicht zu sehen; die mediale Seite M des Schuhs 1 bzw. des Schuhoberteils 2 liegt auf der nicht zu sehenden Rückseite des Schuhs 1 (angedeutet durch das Bezugszeichen M). FIG. 1 shows a shoe 1 in the form of a sports shoe, which has a shoe upper 2 and a sole 32. The lateral side L of the shoe 1 or of the shoe upper 2 can be seen in the illustrated side view; the medial side M of the shoe 1 or the upper 2 of the shoe lies on the non-visible back of the shoe 1 (indicated by the reference M).
Die Schnürung des Schuhs 1 erfolgt mittels eines Drehverschlusses 3 (d. h. eines Zentralverschlusses), wobei durch Drehen einer Spannrolle 7 zwei Spannelemente 4 und 5 auf der Spannrolle aufgewickelt werden und so das Schuhoberteil 2 am Fuß des Trägers des Schuhs 1 gespannt wird. The lacing of the shoe 1 is effected by means of a rotary closure 3 (i.e., a central closure), wherein two tensioning elements 4 and 5 are wound on the tensioning pulley by turning a tensioning roller 7 and thus the shoe upper 2 is tensioned at the foot of the wearer of the shoe 1.
Der Drehverschluss 3 ist auf dem Rist 6 des Schuhs 1 angeordnet. Demgemäß ist eine bequeme Zugänglichkeit zum Drehverschluss 3 durch den Benutzer des Schuhs gewährleistet, der zum Öffnen und Schließen des Drehverschlusses lediglich entsprechende (nicht dargestellte) Schalter betätigen muss, da der Drehverschluss 3 elektromotorisch betätigt ist. The rotary closure 3 is arranged on the instep 6 of the shoe 1. Accordingly, a comfortable accessibility to the rotary closure 3 is ensured by the user of the shoe, the opening and closing of the Rotary closure only corresponding switch (not shown) must operate, since the rotary closure 3 is actuated by an electric motor.
Die Drehachse a der Spannrolle 7 steht dabei senkrecht auf dem Bereich des Rists 6 des Schuhs. The axis of rotation a of the tension roller 7 stands perpendicular to the area of the instep 6 of the shoe.
Zum Öffnen und Schließen des Drehverschlusses 3 ist ein Elektromotor 8 vorgesehen, dessen Drehachse horizontal und quer zur Schuhlängsrichtung ausgerichtet ist. Die Drehbewegung des Elektromotors 8 wird über ein Getriebe 9 auf die Spannrolle 7 übertragen. Die wesentlichen Getriebekomponenten sind in Figur 2 dargestellt. To open and close the rotary closure 3, an electric motor 8 is provided, whose axis of rotation is aligned horizontally and transversely to the shoe longitudinal direction. The rotational movement of the electric motor 8 is transmitted via a gear 9 to the tension roller 7. The main transmission components are shown in FIG.
Hiernach weist das Getriebe 9 zunächst eine erste Stirnradstufe 10 auf, wobei ein Stirnrad 11 der ersten Stirnradstufe 10 mit einem Antriebsritzel 12 des Elektromotors 8 kämmt. Ein mit dem Stirnrad 1 1 der ersten Stirnradstufe 10 drehfest verbundenes Ritzel 13 kämmt mit einem Stirnrad 14 einer zweiten Stirnradstufe 15. After this, the transmission 9 initially has a first spur gear stage 10, wherein a spur gear 11 of the first spur gear stage 10 meshes with a drive sprocket 12 of the electric motor 8. A rotatably connected to the spur gear 1 1 of the first spur gear 10 pinion 13 meshes with a spur gear 14 of a second spur gear 15th
Die zweite Stirnradstufe 15 weist das Stirnrad 14 auf, das drehfest mit einer Schnecke 16 eines Schneckengetriebes 16, 17 drehfest verbunden ist. The second spur gear 15 has the spur gear 14 which is rotatably connected to a worm 16 of a worm gear 16, 17 rotatably connected.
Die Schnecke 16 des Schneckengetriebes 16, 17 kämmt mit einem Schneckenrad 17, wobei die Spannrolle 7 drehfest mit dem Schneckenrad 17 verbunden ist. The worm 16 of the worm gear 16, 17 meshes with a worm wheel 17, wherein the tension roller 7 is rotatably connected to the worm wheel 17.
Die Ritzel 12 bzw. 13 haben bevorzugt zwischen 10 und 14 Zähnen. Die Stirnräder 1 1 und 14 der ersten bzw. zweiten Stirnradstufe 10 bzw. 15 haben bevorzugt zwischen 50 und 70 Zähnen. Mit Blick auf Figur 1 ist zu sehen, dass in der Zwischensohle des Schuhs 1 eine Batterie 18 angeordnet ist, die den Elektromotor 8 mit Energie versorgt. Dabei ist ein Begrenzungselement 19 vorhanden, das den Strom zum Elektromotor 8 begrenzt und so für eine Begrenzung des Drehmoments sorgt, das auf die Spannrolle 7 aufgebracht werden kann. The pinions 12 and 13 preferably have between 10 and 14 teeth. The spur gears 1 1 and 14 of the first and second spur gear 10 and 15 preferably have between 50 and 70 teeth. With reference to Figure 1 it can be seen that in the midsole of the shoe 1, a battery 18 is arranged, which supplies the electric motor 8 with energy. In this case, a limiting element 19 is present, which limits the current to the electric motor 8 and thus provides for a limitation of the torque that can be applied to the tension roller 7.
Zum Aufladen der Batterie 18 ist eine Induktionsspule 20 vorhanden, über die drahtlos Energie in die Batterie eingetragen werden kann. Vorgesehen ist, dass ein erstes Spannelement 4 für die laterale Seite L des Schuhoberteils 2 und ein zweites Spannelement 5 für die mediale Seite M des Schuhoberteils 2 vorhanden sind. To charge the battery 18, an induction coil 20 is provided, via the wireless energy can be entered into the battery. It is provided that a first tension element 4 for the lateral side L of the upper 2 and a second tension element 5 for the medial side M of the upper 2 are provided.
Wie anhand der schematischen Darstellung gemäß Figur 3 gesehen werden kann, sind beide Enden 21 und 22 des ersten Spannelements 4 sowie die beiden Enden 23 und 24 des zweiten Spannelements 5 am Wickelbereich der Spannrolle 7 befestigt, so dass der effektiv für das Spannen zur Verfügung stehende Abschnitt der Spannelemente 4 bzw. 5 durch Drehen der Spannrolle 7 verkürzt werden kann und so die Schnürung des Schuhs erfolgt. As can be seen from the schematic illustration according to FIG. 3, both ends 21 and 22 of the first tensioning element 4 as well as the two ends 23 and 24 of the second tensioning element 5 are fastened to the winding region of the tensioning roller 7, so that the one available for tensioning Section of the clamping elements 4 and 5 can be shortened by turning the tension roller 7 and so the lacing of the shoe takes place.
Der für die laterale Seite L in Figur 1 dargestellte Kurvenzug 25 (s. Fig. 1) des ersten Spannelements 4 kontrahiert daher beim Drehen der Spannrolle 7 und führt dazu, dass das Schuhoberteil 2 an den Fuß des Trägers des Schuhs 1 gezogen wird. The curve 25 (see Fig. 1) of the first tensioning element 4 shown for the lateral side L in Fig. 1 therefore contracts during rotation of the tensioning roller 7 and causes the shoe upper 2 to be pulled against the foot of the wearer of the shoe 1.
Wie in Figur 1 gesehen werden kann, ist der Kurvenzug 25, d. h. die Führung des Spannelements 4 auf der lateralen Seite L des Schuhoberteils 2 (Entsprechendes gilt für die mediale Seite M des Schuhoberteils 2), speziell ausgebildet. Hierfür sind fünf Umlenkelemente vorhanden, nämlich ein erstes Umlenkelement 26, ein zweites Umlenkelement 28, ein drittes Umlenkelement 29, ein viertes Umlenkelement 30 und ein fünftes Umlenkelement 31. As can be seen in FIG. 1, the curve 25, ie the guidance of the tensioning element 4 on the lateral side L of the shoe upper 2 (the same applies to the medial side M of the shoe upper 2), is specially designed. For this purpose, five deflecting elements are present, namely a first Deflection element 26, a second deflecting element 28, a third deflecting element 29, a fourth deflecting element 30 and a fifth deflecting element 31.
Das erste Umlenkelement 26 ist dabei im vorderen Bereich des Schuhs angeordnet, und zwar an einer Längsposition des Schuhs, die zwischen 30 % und 42 % der gesamten Schuhlängserstreckung GL entspricht, gemessen von der Schuhspitze 27. Das als Schlaufe ausgebildete Umlenkelement 26 setzt dabei im wesentlichen im Übergangsbereich zwischen der Sohle 32 und Schuhoberteil 2 an. The first deflection element 26 is arranged in the front region of the shoe, namely at a longitudinal position of the shoe, which corresponds to between 30% and 42% of the total shoe extension GL, measured from the toe 27. The trained as a loop deflecting element 26 is essentially in the transition region between the sole 32 and shoe upper 2.
Das zweite Umlenkelement 28 ist so platziert, dass das Spannelement 4 im wesentlichen horizontal vom ersten Umlenkelement 26 nach hinten (in Richtung Ferse) geführt wird. Die Längsposition des zweiten Umlenkelements 28 liegt bei einer Marke zwischen 50 % und 60 % der Schuhlängserstreckung GL, wiederum gerechnet von der Schuhspitze 27. The second deflection element 28 is placed so that the tensioning element 4 is guided substantially horizontally from the first deflection element 26 to the rear (in the direction of the heel). The longitudinal position of the second deflecting element 28 lies at a mark between 50% and 60% of the shoe longitudinal extent GL, again calculated from the toe 27.
Vom zweiten Umlenkelement 28 wird das Spannelement 4 nach oben in Richtung Drehverschluss 3 geführt. Unterhalb des Drehverschlusses 3 befindet sich ein drittes Umlenkelement 29, das das Spannelement 4 im wesentlichen um 180° umlenkt und wiederum nach unten führt, nämlich zu einem vierten Umlenkelement 30, das bei einer Marke zwischen 55 % und 70 % der Schuhlängserstreckung GL liegt. From the second deflection element 28, the clamping element 4 is guided upward in the direction of rotary closure 3. Below the rotary closure 3 is a third deflecting element 29, which deflects the clamping element 4 substantially by 180 ° and in turn leads downwards, namely to a fourth deflecting element 30, which is at a mark between 55% and 70% of the shoe longitudinal extent GL.
Schließlich wird das Spannelement 4 vom vierten Umlenkelement 30 zu einem fünften Umlenkelement 31 geführt, das bezüglich seiner Höhenposition auf einem Niveau zwischen 33 % und 66 % der Gesamthöhe des Schuhs liegt. Hinsichtlich der Längsposition befindet sich das fünfte Umlenkelement 31 an einer Stelle, die im Bereich zwischen 75 % und 90 % der Schuhlängserstreckung GL liegt, gemessen ab der Schuhspitze 27. Vom fünften Umlenkelement 31 läuft das Spannelement 4 dann zurück zum Drehverschluss 3. Finally, the clamping element 4 is guided by the fourth deflecting element 30 to a fifth deflecting element 31, which lies with respect to its height position at a level between 33% and 66% of the total height of the shoe. With regard to the longitudinal position, the fifth deflecting element 31 is located at a point which is in the range between 75% and 90% of the shoe extension SE, measured from the toe 27. From the fifth Deflection element 31 then runs the clamping element 4 back to the rotary closure. 3
Alle Umlenkelemente 26, 28, 29, 30 und 31 sind im Ausführungsbeispiel als Bänder ausgeführt, die zu einer Schlaufe geformt und am Schuhoberteil befestigt sind. Hinsichtlich des fünften Umlenkelements 31 ist zu erkennen, dass dieses um den Fersenbereich 33 des Schuhs 1 herumläuft bzw. in diesem angreift. Die beiden in Figur 1 zu sehenden rechts liegenden Endbereiche des fünften Umlenkelements 31 greifen dabei an unterschiedlichen Höhenpositionen der Ferse 33 an, nämlich einmal relativ tief nahe der Sohle 32 und einmal nur etwas unterhalb des oberen Endes der Ferse 33. Es ergibt sich folglich die dargestellte V-förmige Struktur. All deflection elements 26, 28, 29, 30 and 31 are designed in the embodiment as bands, which are formed into a loop and attached to the shoe upper. With regard to the fifth deflecting element 31, it can be seen that this runs around the heel region 33 of the shoe 1 or engages in it. The two end regions of the fifth deflecting element 31 which can be seen in FIG. 1 engage at different height positions of the heel 33, namely once relatively deep near the sole 32 and once only slightly below the upper end of the heel 33. Consequently, the result is shown V-shaped structure.
Die Kurvenzüge 25 sind auf beiden Seiten des Schuhoberteils 2 weitgehend symmetrisch ausgebildet, und zwar zu einer Mittenebene, die mittig im Schuh 1 liegt, vertikal ausgerichtet ist und in Schuhlängsrichtung verläuft. Mit der vorgeschlagenen Ausgestaltung kann nicht nur der Schuh sehr einfach durch elektromotorisches betätigtes Drehen der Spannrolle 7 vom Träger des Schuhs geschnürt werden, der Druck der Spannelemente 4 und 5 wird auch sehr gleichmäßig verteilt und führt zu einer homogenen Anlage des Schuhs 1 am Fuß des Trägers. The curves 25 are formed on both sides of the shoe upper 2 largely symmetrical, to a central plane, which is located centrally in the shoe 1, is vertically aligned and runs in the shoe longitudinal direction. With the proposed embodiment not only the shoe can be laced very easily by electromotive actuated turning the tension roller 7 from the wearer of the shoe, the pressure of the clamping elements 4 and 5 is also very evenly distributed and leads to a homogeneous investment of the shoe 1 at the foot of the wearer ,
Vorgesehen kann dabei werden, dass die äußerste Lage des Schuhoberteils 2 die Spannelemente 4 und 5 abdeckt, so dass diese nicht zu sehen sind.
