DETAILED DESCRIPTION OF THE INVENTION

(7) In FIG. 1 a shoe 1 being a sports shoe can be seen which has an upper 2 and a sole 11. The lacing of the shoe 1 takes place by means of a rotating closure 3 (i. e. of a central fastener), wherein by rotating of a tensioning roller 5 at least one tensioning element 4 is winded on the tensioning roller 5 and thus the upper 2 is tensioned and laced respectively at the foot of the wearer of the shoe 1.

(8) The rotating closure 3 is arranged on the instep 10 of the shoe 1. The axis of rotation of the tensioning roller is thereby perpendicular to the region of the instep 10 of the shoe 1. Accordingly, a convenient access to the rotating closure 3 is ensured for the user of the shoe who must only actuate corresponding buttons, namely a closing button 7 and an opening button 9 (s. FIG. 2), for opening and closing of the rotating closure because the rotating closure 3 is electric motor operated. The electric motor 6 is indicated which is required for that; it can drive the tensioning roller 5 via anot depictedgear. In the embodiment the axis of rotation of the electric motor 6 is arranged horizontally and transverse to the longitudinal direction of the shoe.

(9) The actuation of the electric motor 6 for the opening and the closing of the rotating closure 3 is initiated by a control system 8 which is correspondingly also connected with the closing button 7 and the opening button 9.

(10) For closing of the shoe 1 the user proceeds as follows:

(11) When he wants to put on the shoe at his foot with a first (low) tensioning force level he taps once onto the closing button 7. This tap impulse is denoted in FIG. 3a with the arrow. The control system 8 registers the tap impulse and waits a waiting time tW to find out if further tap impulses follow by the user. If this is not the case the software which is stored in the control system 8 knows that the user wanted to give a first closing signal S1 which corresponds to said first tensioning force level.

(12) Accordingly the electric motor 6 is driven until a first predetermined maximum value for the motor current is given, for example 1.5 A.

(13) When the user wants to put on the shoe at his foot with a second (medium) tensioning force level he taps twice onto the closing button 7. This sequence of tap impulses is denoted in FIG. 3b with the arrows. The control system 8 registers again the tap impulses wherein intended double impulsesas shown in FIG. 3bcan be identified by the fact that they follow within a predetermined following time tF. Otherwise the control system waits again the waiting time tW after the last identified tap impulse to find out if still further tap impulses follow by the user. If this is not the case the software which is stored in the control system 8 knows that the user wanted to give said second closing signal S2 which corresponds to said second tensioning force level.

(14) Accordingly the electric motor 6 is driven now until a second predetermined maximum value for the motor current is given which is higher than the first value, for example 2.5 A.

(15) The analogue applies, when the user wants to put on the shoe at his foot with a third (high) tensioning force level. He taps in this case three times onto the closing button 7. This sequence of tap impulses is denoted in FIG. 3c with the arrows. The control system 8 registers again the tap impulses wherein intended multiple impulseas shown in FIG. 3ccan be identified by the fact that the time distance between two tap impulses is within the predetermined following time tF. Otherwise the control system waits again the waiting time tW after the last identified tap impulse to find out if still further tap impulses follow by the user. If this is not the case the software which is stored in the control system 8 knows that the user wanted to give said third closing signal S3 which corresponds to said third tensioning force level.

(16) Accordingly the electric motor 6 is driven now until a third predetermined maximum value for the motor current is given which is higher than the second value, for example 3.5 A.

(17) Accordingly the possibility exists by the proposed proceedings to reach a selective tensioning force level by different closing signals S1, S2 and S3 respectively.

(18) The user needs notas in the state of the artactuate the closing button 7 for a longer time; rather it is sufficient that he gives the respective sequence of impulses. Furthermore, the user can thereby directly obtain a tensioning force level which fits to his desires without adjusting the same by a respective long pressing of the closing button.

(19) When the shoe fits at least with the first tensioning force level at the foot of the user and when the user presses once onto the closing button 7, when he thus gives a single tap impulse onto the button, the next tensioning force level can be automatically obtained according to a further embodiment, thus from the first into the second tensioning force level or from the second into the third tensioning force level. This is mentioned above when reciting the further closing signal which is applied in the given case by the user to the closing button.

(20) For opening of the shoe, i. e. for releasing of the tensioning element 4, the user presses once onto the opening button 9. The electric motor 6 drives then into the completely tensionless state which can detected by a respective rotation angle sensor at the tensioning roller 5.
