Description

Die Erfindung betrifft ein Verfahren zum Schnüren eines Schuhs, insbesondere eines Sportschuhs, wobei der Schuh aufweist:

  • ein Schuhoberteil, wobei an oder auf dem Schuhoberteil ein Drehverschluss zum Schnüren des Schuhs am Fuß des Trägers mittels mindestens eines Spannelements angeordnet ist,
  • wobei der Drehverschluss eine drehbar angeordnete Spannrolle aufweist, wobei die Spannrolle mittels eines Elektromotors angetrieben wird,
  • wobei der Drehverschluss weiterhin mindestens einen Schließ-Schalter aufweist oder umfasst, der mit einer Steuerung in Verbindung steht, die den Elektromotor betätigt,
wobei das Schnüren des Schuhs erfolgt, indem der Benutzer des Schuhs auf den Schließ-Schalter ein Schließsignal aufgibt.The invention relates to a method for lacing a shoe, in particular a sports shoe, the shoe comprising:
  • a shoe upper, wherein on or on the shoe upper a screw cap for lacing the shoe is arranged at the foot of the carrier by means of at least one tensioning element,
  • wherein the rotary closure has a rotatably arranged tensioning roller, wherein the tensioning roller is driven by means of an electric motor,
  • wherein the rotary closure further comprises or comprises at least one closing switch which is in communication with a controller which actuates the electric motor,
wherein the lacing of the shoe is done by the user of the shoe on the closing switch gives a closing signal.

Ein Schuh mit einem elektromotorisch betriebenen Drehverschlusses ist aus der DE 298 17 003 U1 bekannt. Hier wird eine Spannrolle zum Aufwickeln eines Spannelements elektromotorisch angetrieben, so dass der Schuh automatisch geschnürt und entschnürt werden kann.A shoe with an electric motor driven rotary closure is from the DE 298 17 003 U1 known. Here is a tensioner for winding a tensioning element driven by an electric motor, so that the shoe can be laced and untied automatically.

Zum Schnüren des Schuhs wird vom Benutzer ein elektrischer Schalter betätigt und der Elektromotor des Drehverschlusses solange aktiviert, wie der Schalter gedrückt wird. Entsprechend steigt die Schnürkraft allmählich an. Ist ein gewünschtes Schnürkraftniveau erreicht, lässt der Benutzer den Schalter wieder los. Zum Entschnüren des Schuhs kann entsprechend ein anderer Schalter betätigt werden.To lace the shoe, an electrical switch is actuated by the user and the electric motor of the rotary closure is activated as long as the switch is pressed. Accordingly, the lacing gradually increases. When a desired lacing level is reached, the user releases the switch. To untie the shoe can be operated according to another switch.

Demgemäß benötigt das Schnüren des Schuhs eine entsprechende Zeit, während der der Benutzer den Schalter drücken muss. Außerdem muss das jeweils gewünschte Schnürkraftniveau bei jeder Schnürung vom Benutzer eingestellt werden.Accordingly, lacing the shoe requires a corresponding amount of time during which the user must press the switch. In addition, the desired Schnürkraftniveau must be set at each lacing by the user.

Ein Verfahren der gattungsgemäßen Art ist in der WO 2014/036374 A1 offenbart. Ähnliche und andere Lösungen zeigen die US 2014/0082963 A1 und die US 2015/0289594 A1 . A method of the generic type is in the WO 2014/036374 A1 disclosed. Similar and other solutions show the US 2014/0082963 A1 and the US 2015/0289594 A1 ,

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art so weiterzubilden, dass das Schnüren des Schuhs komfortabler und in vereinfachter Weise bewerkstelligt werden kann. Dabei soll es insbesondere möglich sein, bedienerfreundlich die Schnürung des Schuhs an individuelle Wünsche anpassen zu können. Damit soll ohne großen Bedienaufwand der Schuh gemäß den Wünschen des Benutzers mit einem definierten Schnürkraftniveau anlegbar sein.The invention has the object of developing a method of the type mentioned so that the lacing of the shoe can be accomplished more comfortable and in a simplified manner. It should be possible in particular, user-friendly to be able to adapt the lacing of the shoe to individual needs. This should be able to be applied according to the wishes of the user with a defined lace level without great effort.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass das Verfahren die Schritte umfasst:

  • Schnüren des Schuhs mit einem ersten Schnürkraftniveau, das eine erste Spannung des mindestens einen Spannelements zur Folge hat, wenn der Benutzer des Schuhs auf den Schließ-Schalter ein erstes Schließsignal aufgibt, wobei das erste Schließsignal ein einmaliges Antippen des Schließ-Schalters ist, auf das innerhalb einer vorgegebenen Wartezeit kein weiterer Tipp-Impuls folgt, oder alternativ bzw. additiv
  • Schnüren des Schuhs mit einem zweiten Schnürkraftniveau, das eine zweite Spannung des mindestens einen Spannelements zur Folge hat, die größer ist als die erste Spannung, wenn der Benutzer des Schuhs auf den Schließ-Schalter ein zweites Schließsignal aufgibt, das sich vom ersten Schließsignal unterscheidet, wobei das zweite Schließsignal ein zweimaliges Antippen des Schließ-Schalters ist, wobei die beiden Tipp-Impulse innerhalb einer vorgegebenen Folgezeit aufeinander folgen und wobei auf die beiden Tipp-Impulse innerhalb einer vorgegebenen Wartezeit kein weiterer Tipp-Impuls folgt.
The solution of this problem by the invention is characterized in that the method comprises the steps:
  • Lace the shoe at a first lace level that results in a first tension of the at least one lace when the user of the shoe places a first close on the close button, the first close signal being a single tap of the close button on the first button within a given waiting time no further tapping pulse follows, or alternatively or additively
  • Lacing the shoe at a second lace level that results in a second tension of the at least one tension element greater than the first tension when the user of the shoe places a second close signal on the close button that is different than the first close signal; wherein the second closing signal is a two-time tap of the closing switch, wherein the two tapping pulses follow each other within a predetermined time sequence and wherein the two tapping pulses within a predetermined waiting time no further tapping pulse follows.

In Fortführung dieses Konzepts kann weiter vorgesehen werden, dass das Verfahren alternativ bzw. additiv den weiteren Schritt aufweist:

  • Schnüren des Schuhs mit einem dritten Schnürkraftniveau, das eine dritte Spannung des mindestens einen Spannelements zur Folge hat, die größer ist als die zweite Spannung, wenn der Benutzer des Schuhs auf den Schließ-Schalter ein drittes Schließsignal aufgibt, das sich vom ersten und vom zweiten Schließsignal unterscheidet.
Continuing this concept, it can further be provided that the method alternatively or additionally has the further step:
  • Lace the shoe at a third lace level that results in a third tension of the at least one tension element greater than the second tension when the user of the shoe places a third lock signal on the close switch extending from the first and second Lock signal distinguishes.

Nach dem Anfahren des ersten oder zweiten Schnürkraftniveaus in Abhängigkeit des aufgegebenen Schließsignals kann gemäß einer Weiterbildung der Schritt ausgeführt werden:

  • Erhöhung des Schnürkraftniveaus vom ersten Schnürkraftniveau zum zweiten Schnürkraftniveau oder vom zweiten Schnürkraftniveau zum dritten Schnürkraftniveau, indem der Benutzer des Schuhs auf den Schließ-Schalter ein weiteres Schließsignal aufgibt.
After starting the first or second Schnürkraftniveaus depending on the abandoned closing signal can be executed according to a further development of the step:
  • Increasing the lacing level from the first lacing level to the second lacing level or from the second lacing level to the third lacing level by giving the user of the shoe another closing signal on the closing switch.

Dieses weitere Schließsignal ist bevorzugt ein einmaliges Antippen des Schließ-Schalter.This further closing signal is preferably a single tap of the closing switch.

Demgemäß bietet das vorgeschlagene Konzept zunächst die Möglichkeit, elektromotorisch unterschiedliche Schnürkraftniveaus anzufahren, wobei das jeweilige Schnürkraftniveau durch Eingabe eines individuellen Schließsignals angefahren wird. Ist das erste oder das zweite Schnürkraftniveau bereits erreicht und gibt der Benutzer auf den Schließ-Schalter ein weiteres Schließsignal auf, wird automatisch ein Schnürkraftniveau mit höherer Schnürkraft angefahren.Accordingly, the proposed concept initially offers the possibility of approaching electric motor different Schnürkraftniveaus, the respective Schnürkraftniveau is approached by entering an individual closing signal. If the first or the second Schnürkraftniveau has already been reached and gives the user on the closing switch on another closing signal, a Schnürkraftniveau is automatically approached with higher lacing.

Das dritte Schließsignal ist bevorzugt ein dreimaliges Antippen des Schließ-Schalters, wobei jeweils zwei der Tipp-Impulse innerhalb einer vorgegebenen Folgezeit aufeinander folgen und wobei auf die drei Tipp-Impulse innerhalb einer vorgegebenen Wartezeit kein weiterer Tipp-Impuls folgt.The third closing signal is preferably a triple tapping of the closing switch, with two of the tapping pulses following each other within a predetermined follow-up time and with no further tapping pulse following the three tapping pulses within a predetermined waiting time.

Die Wartezeit beträgt bevorzugt höchstens 1,0 Sekunden.The waiting time is preferably at most 1.0 seconds.

Die Folgezeit liegt bevorzugt zwischen 0,05 Sekunden und 0,75 Sekunden, besonders bevorzugt zwischen 0,1 Sekunden und 0,5 Sekunden.The follow-up time is preferably between 0.05 seconds and 0.75 seconds, more preferably between 0.1 seconds and 0.5 seconds.

Das erste Schnürkraftniveau wird dabei vorzugsweise durch einen ersten vorgegebenen maximalen Strom definiert, den die Steuerung dem Elektromotor beim Schnürvorgang vorgibt; besagter Strom beträgt dabei bevorzugt zwischen 1,1 A und 1,9 A.The first Schnürkraftniveau is preferably defined by a first predetermined maximum current, which dictates the control of the electric motor during lacing; said current is preferably between 1.1 A and 1.9 A.

Das zweite Schnürkraftniveau wird analog bevorzugt durch einen zweiten vorgegebenen maximalen Strom definiert, den die Steuerung dem Elektromotor beim Schnürvorgang vorgibt, wobei der zweite maximale Strom höher ist als der erste maximale Strom; besagter Strom liegt bevorzugt zwischen 2,1 A und 2,9 A.The second Schnürkraftniveau is analogously preferably defined by a second predetermined maximum current that dictates the control of the electric motor during lacing, wherein the second maximum current is higher than the first maximum current; said current is preferably between 2.1 A and 2.9 A.

Das dritte Schnürkraftniveau wird entsprechend bevorzugt durch einen dritten vorgegebenen maximalen Strom definiert, den die Steuerung dem Elektromotor beim Schnürvorgang vorgibt, wobei der dritte maximale Strom höher ist als der zweite maximale Strom; der Strom liegt bevorzugt zwischen 3,1 A und 3,9 A.Accordingly, the third lace load level is preferably defined by a third predetermined maximum current that the control dictates to the electric motor during the lacing operation, wherein the third maximum current is higher than the second maximum current; the current is preferably between 3.1 A and 3.9 A.

Die Steuerung kann auch die Entspannung des mindestens einen Spannelements veranlassen, wenn ein Öffnungs-Schalter betätigt wird, der vom Schließ-Schalter unterschiedlich ist.The controller may also cause the relaxation of the at least one tensioning element when an opening switch is actuated, which is different from the closing switch.

Dabei wird bevorzugt ein Drehverschluss verwendet, bei dem zwischen dem Spannelement und dem Elektromotor ein Getriebe angeordnet ist.In this case, a rotary closure is preferably used, in which a transmission is arranged between the clamping element and the electric motor.

Der Drehverschluss wird bevorzugt auf dem Rist des Schuhs angeordnet. Die Drehachse der Spannrolle steht dabei bevorzugt auf der Oberfläche des Schuhs im Bereich des Rists senkrecht.The rotary closure is preferably arranged on the instep of the shoe. The axis of rotation of the tensioning roller is preferably perpendicular to the surface of the shoe in the region of the instep.

Weiterhin sieht eine vorteilhafte Fortbildung einen Drehverschluss vor, bei dem der Schließ-Schalter und der gegebenenfalls vorhandene Öffnungs-Schalter auf dem Drehverschluss angeordnet sind.Furthermore, an advantageous development provides a rotary closure in which the closing switch and the optional opening switch are arranged on the rotary closure.

Als spezielle Ausführungsform der Erfindung kann eine Steuerung zum Einsatz kommen, die über eine drahtlose Verbindung, insbesondere über eine Bluetooth-Verbindung, mit einem Mobiltelefon (Smartphone) in Verbindung steht, wobei der Schließ-Schalter und der gegebenenfalls vorhandene Öffnungs-Schalter durch das Mobiltelefon gebildet werden. Demnach kann also auch Steuerung des Drehverschlusses auf drahtlose Weise per Bluetooth über ein Smartphone vorgesehen werden, das zu diesem Zwecke mit einer entsprechenden App versehen ist.As a specific embodiment of the invention, a controller may be used, which is connected via a wireless connection, in particular via a Bluetooth connection, with a mobile phone (smartphone), wherein the closing switch and the possibly existing opening switch by the mobile phone be formed. Accordingly, therefore, control of the rotary closure can be provided wirelessly via Bluetooth via a smartphone, which is provided for this purpose with a corresponding app.

Die Drehachse des Elektromotors steht bevorzugt horizontal und quer zur Längsrichtung des Schuhs.The axis of rotation of the electric motor is preferably horizontal and transverse to the longitudinal direction of the shoe.

Die Spannelemente sind bevorzugt Spanndrähte. Sie können Polyamid aufweisen oder aus diesem Material bestehen.The clamping elements are preferably tension wires. You can have polyamide or consist of this material.

Die Batterie, die für den Betrieb des Motors benötigt wird, ist bevorzugt als wiederaufladbare Batterie ausgebildet. Diese kann über eine Induktionsspule mit einem Ladestrom versorgt werden. 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.The battery that is required for the operation of the engine is preferably designed as a rechargeable battery. This can be supplied via an induction coil with a charging current. 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.

Demgemäß stellt das vorgeschlagene Konzept darauf ab, durch unterschiedliche Signale (also beispielsweise einmaliges Tippen, zweimaliges Tippen bzw. dreimaliges Tippen auf den Schließ-Schalter) dem motorisierten Drehverschluss bis zu definierten jeweiligen Schließpositionen bzw. auf entsprechende Schnürkraftniveaus zu fahren. Besagte Schnürkraftniveaus sind dabei bevorzugt durch Vorgabe eines entsprechenden Motorstroms definiert (z. B. erstes Niveau: 1,5 A - zweites Niveau: 2,5 A - drittes Niveau: 3,5 A), so dass der Motor mit korrespondierenden maximalen Drehmomenten betrieben wird, was wiederum über das verwendete Getriebe zu einer korrespondierenden zunehmenden Zugkraft im Spannelement führt.Accordingly, the proposed concept is based on different signals (ie, for example, single tap, double tap or three times tapping on the closing switch) to drive the motorized rotary shutter up to defined respective closing positions or to corresponding Schnürkraftniveaus. Said Schnürkraftniveaus are preferably defined by specifying a corresponding motor current (eg, first level: 1.5 A - second level: 2.5 A - third level: 3.5 A), so that the engine operated with corresponding maximum torques which in turn leads via the gear used to a corresponding increasing tensile force in the clamping element.

Ein mehrmaliges Tippen auf den Schließ-Schalter erkennt die Steuerung dadurch, dass die Tippimpulse in einem maximalen zeitlichen Abstand liegen (s. oben genannte Folgezeit); ferner wird das vom Benutzer des Schuhs gewünschte Signal dadurch erkannt, dass nach den registrierten Tippimpulsen binnen einer vorgegebenen Wartezeit kein weiterer Impuls detektiert wird.A repeated touch of the close button detects the controller in that the tapping pulses are at a maximum time interval (see above following time); Furthermore, the signal desired by the user of the shoe is recognized by the fact that no further pulse is detected within a predetermined waiting time after the registered tapping pulses.

Neben diesem direkten Anfahren der (drei) genannten Schnürkraftniveaus besteht auch die Möglichkeit, nach dem Anziehen des Schuhs durch einmaliges Tippen in das nächsthöhere Schnürkraftniveau zu fahren.In addition to this direct approach of the (three) mentioned Schnürkraftniveaus there is also the possibility to go after putting on the shoe by tapping once in the next higher lacing level.

Das (vollständige) Öffnen der Schnürung kann in einem Schritt nach der Betätigung eines entsprechenden Öffnungs-Schalters erfolgen. Für die vollständig entschnürte Endposition kann die Spannrolle mit einem Drehwinkelsensor versehen sein, der in der Lage ist, die Null-Position der Spannrolle zu erkennen.The (complete) opening of the lacing can be done in one step after the operation of a corresponding opening switch. For the fully decoupled end position, the tension roller may be provided with a rotation angle sensor capable of detecting the zero position of the tension roller.

Natürlich kann das oben beschriebene Verfahren auch mit mehr als drei verschiedenen Schnürkraftniveaus realisiert werden.Of course, the method described above can also be realized with more than three different lace levels.

In vorteilhafter Weise kann so der Bedienungskomfort bei der Benutzung eines Schuhs mit elektromotorischem Schnürsystem per Drehverschluss verbessert werden.Advantageously, the ease of use when using a shoe with electromotive lacing system can be improved by twist-lock.

Der Drehverschluss 3 ist auf dem Rist 10 des Schuhs 1 angeordnet. Die Drehachse der Spannrolle 5 steht dabei senkrecht auf dem Bereich des Rists 10 des Schuhs 1. Demgemäß ist eine bequeme Zugänglichkeit zum Drehverschluss 3 durch den Benutzer des Schuhs gewährleistet, der zum Öffnen und Schließen des Drehverschlusses lediglich entsprechende Schalter, nämlich einen Schließ-Schalter 7 und einen Öffnungs-Schalter 9 (s. hierzu Fig. 2), betätigen muss, da der Drehverschluss 3 elektromotorisch betätigt ist. Der hierzu benötigte Elektromotor 6 ist angedeutet; er kann über ein - nicht dargestelltes - Getriebe die Spannrolle 5 antreiben. Die Drehachse des Elektromotors 6 liegt im Ausführungsbeispiel horizontal und quer zur Schuhlängsrichtung.The rotary closure 3 is arranged on the instep 10 of the shoe 1. The axis of rotation of the tension roller 5 is perpendicular to the area of the instep 10 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, namely a closing switch and an opening switch 9 (see Fig. 2 ), must operate, since the rotary closure 3 is actuated by an electric motor. The electric motor 6 required for this purpose is indicated; he can drive the tension roller 5 via a - not shown - gear. The axis of rotation of the electric motor 6 is horizontal in the embodiment and transverse to the shoe longitudinal direction.

Die Betätigung des Elektromotors 6 zum Öffnen und Schließen des Drehverschlusses 3 wird von einer Steuerung 8 veranlasst, die entsprechend auch mit dem Schließ-Schalter 7 und dem Öffnungs-Schalter 9 verbunden ist.The operation of the electric motor 6 for opening and closing the rotary closure 3 is initiated by a controller 8, which is also connected to the closing switch 7 and the opening switch 9 accordingly.

Zum Schließen des Schuhs 1 geht der Benutzer wie folgt vor:
Will er den Schuh mit einem ersten (niedrigen) Schnürkraftniveau an seinem Fuß anlegen, tippt er einmalig auf den Schließ-Schalter 7. Dieser Tipp-Impuls ist in Figur 3a mit dem Pfeil dargestellt. Die Steuerung 8 registriert den Tipp-Impuls und wartet eine Wartezeit tw ab, um festzustellen, ob weitere Tipp-Impulse vom Benutzer folgen. Ist dies nicht der Fall, weiß die in der Steuerung 8 gespeicherte Software, dass der Benutzer ein erstes Schließsignal S1 abgeben wollte, das zu besagtem ersten Schnürkraftniveau korrespondiert.To close the shoe 1, the user proceeds as follows:
If he wants to create the shoe with a first (low) lacing level on his foot, he taps once on the closing switch 7. This tip-impulse is in FIG. 3a represented by the arrow. The controller 8 registers the jogging pulse and waits for a waiting time t w to determine if further jogging pulses follow from the user. If this is not the case, the software stored in the controller 8 knows that the user wanted to deliver a first closing signal S 1 corresponding to said first lacing force level.

Demgemäß wird der Elektromotor 6 angetrieben, bis ein erster, vorgegebener Maximalwert für den Motorstrom vorliegt, beispielsweise 1,5 A.Accordingly, the electric motor 6 is driven until a first, predetermined maximum value for the motor current is present, for example 1.5 A.

Will der Benutzer den Schuh mit einem zweiten (mittleren) Schnürkraftniveau an seinem Fuß anlegen, tippt er zweimalig auf den Schließ-Schalter 7. Diese Abfolge von Tipp-Impulsen ist in Figur 3b mit den Pfeilen dargestellt. Die Steuerung 8 registriert wiederum die Tipp-Impulse, wobei beabsichtigte Doppelimpulse - wie in Figur 3b dargestellt - dadurch erkannt werden können, dass sie binnen einer vorgegebenen Folgezeit tF aufeinanderfolgen. Ansonsten wartet die Steuerung wiederum nach dem letzten wahrgenommenen Tipp-Impuls die Wartezeit tw ab, um festzustellen, ob noch weitere Tipp-Impulse vom Benutzer folgen. Ist dies nicht der Fall, weiß die in der Steuerung 8 gespeicherte Software, dass der Benutzer das genannte zweite Schließsignal S2 abgeben wollte, das zu besagtem zweiten Schnürkraftniveau korrespondiert.If the user wants to apply the shoe to his foot with a second (middle) lace-up level, he taps twice on the close button 7. This sequence of jogging pulses is in FIG. 3b shown with the arrows. The controller 8 in turn registers the jogging pulses, with intentional double pulses - as in FIG. 3b represented - can be recognized by the fact that they follow one another within a predetermined follow time t F. Otherwise, control again waits after the last perceived Tip pulse the waiting time t w off to determine whether to follow another tip pulses by the user. If this is not the case, the software stored in the controller 8 knows that the user wanted to deliver the said second closing signal S 2 , which corresponds to said second lacing force level.

Demgemäß wird der Elektromotor 6 jetzt angetrieben, bis ein zweiter, vorgegebener Maximalwert für den Motorstrom vorliegt, der höher als der erste Wert ist, beispielsweise 2,5 A.Accordingly, the electric motor 6 is now driven until there is a second, predetermined maximum value for the motor current, which is higher than the first value, for example 2.5 A.

Analoges gilt, wenn der Benutzer den Schuh mit einem dritten (hohen) Schnürkraftniveau an seinem Fuß anlegen will. Er tippt in diesem Falle drei Mal auf den Schließ-Schalter 7. Diese Abfolge von Tipp-Impulsen ist in Figur 3c mit den Pfeilen dargestellt. Die Steuerung 8 registriert wiederum die Tipp-Impulse, wobei der beabsichtigte Mehrfachimpuls - wie in Figur 3c dargestellt - dadurch erkannt werden kann, dass der zeitliche Abstand zwischen zwei Tipp-Impulsen innerhalb der vorgegebenen Folgezeit tF liegt. Ansonsten wartet die Steuerung wiederum nach dem letzten wahrgenommenen Tipp-Impuls die Wartezeit tw ab, um festzustellen, ob noch weitere Tipp-Impulse vom Benutzer folgen. Ist dies nicht der Fall, weiß die in der Steuerung 8 gespeicherte Software, dass der Benutzer das genannte dritte Schließsignal S3 abgeben wollte, das zu besagtem dritten Schnürkraftniveau korrespondiert.The same applies if the user wants to create the shoe with a third (high) lacing level on his foot. In this case, he taps the close switch 7 three times. This sequence of jogging pulses is in Figure 3c shown with the arrows. The controller 8 in turn registers the jogging pulses, the intended multi-pulse - as in Figure 3c shown - can be detected by the fact that the time interval between two jogging pulses within the predetermined follow time t F is. Otherwise, the control waits again for the last sensed Tip pulse the waiting time t w from to see if there are more tap pulses from the user follow. If this is not the case, the software stored in the controller 8 knows that the user wanted to deliver the said third closing signal S 3 , which corresponds to said third lacing force level.

Demgemäß wird der Elektromotor 6 jetzt angetrieben, bis ein dritter, vorgegebener Maximalwert für den Motorstrom vorliegt, der höher als der zweite Wert ist, beispielsweise 3,5 A.Accordingly, the electric motor 6 is now driven until there is a third predetermined maximum value for the motor current which is higher than the second value, for example 3.5 A.

Demgemäß besteht mit der vorgeschlagenen Vorgehensweise die Möglichkeit, durch unterschiedliche Schließsignale S1, S2 bzw. S3 gezielt ein bestimmtes Schnürkraftniveau anzufahren.Accordingly, there is the possibility with the proposed approach to selectively approach a certain laceing level by means of different closing signals S 1 , S 2 or S 3 .

Der Benutzer muss hierfür nicht - wie im Stand der Technik - längere Zeit den Schließ-Schalter 7 betätigen; es reicht hierfür vielmehr die Abgabe der entsprechenden Impuls-Abfolge. Außerdem kann der Benutzer hierdurch ein für seine Wünsche passendes Schnürkraftniveau direkt anfahren, ohne dass er dies durch entsprechend langes Drücken des Schließ-Schalters einstellen muss.The user does not have to operate the closing switch 7 for a long time, as in the prior art; Rather, it is sufficient for this the delivery of the corresponding pulse sequence. In addition, the user can thereby directly approach a suitable for his desires Schnürkraftniveau, without having to adjust this by a correspondingly long press the closing switch.

Liegt der Schuh mindestens mit dem ersten Schnürkraftniveau am Fuß des Benutzers an und drückt dieser einmalig auf den Schließ-Schalter 7, gibt er also einen einzelnen Tipp-Impuls auf den Schalter ab, kann weiterbildungsgemäß automatisch ins nächste Schnürkraftniveau gefahren werden, also vom ersten ins zweite Schnürkraftniveau oder vom zweiten ins dritte Schnürkraftniveau. Dies ist oben mit dem weiteren Schließsignal angesprochen, das im gegebenen Falle vom Benutzer auf den Schließ-Schalter aufgegeben wird.If the shoe is at least at the first Schnürkraftniveau at the foot of the user and presses it once on the closing switch 7, so he gives a single tap impulse on the switch off, can continue automatically driven to the next Schnürkraftniveau, so from the first ins second lace level or from second to third lace level. This is addressed above with the further closing signal, which is given in the given case by the user on the closing switch.

Zum Öffnen des Schuhs, d. h. zur Entspannung des Spannelements 4, drückt der Benutzer einmalig auf den Öffnungs-Schalter 9. Der Elektromotor 6 fährt dann in den vollständig entspannten Zustand, der durch einen entsprechenden Drehwinkelsensor an der Spannrolle 5 ermittelt werden kann.To open the shoe, ie for relaxation of the tensioning element 4, the user presses once on the opening switch 9. The electric motor 6 then moves into the fully relaxed state, which can be determined by a corresponding rotation angle sensor on the tension roller 5.
