• ein Schaltelement, das mit einer Steuerung in Verbindung steht, wobei über das Schaltelement und die Steuerung der Elektromotor betätigt werden kann,

wobei das Spannen der Mütze, der Jacke, der Hose, des Kapuzenpullis, des BHs oder des Gürtels am Träger oder Entspannen derselben oder desselben vom Träger oder das Schließen, Anlegen, Öffnen oder Ablegen des Rucksacks oder der Sport- oder Reisetasche erfolgt, indem der Benutzer derselben oder desselben das Schaltelement, vorzugsweise mit einem Finger, betätigt.The invention relates to a method for putting on or taking off a cap, jacket, trousers, hooded sweater, bra or belt on the wearer or by the wearer of the same or for closing, putting on, opening or taking off a backpack worn by a person or a sports or travel bag, where the cap, jacket, trousers, hoodie, bra, belt, backpack or sports or travel bag have:

• a twist lock for tensioning the cap, jacket, pants, hoodie, bra or belt on the wearer or relaxing the same or the same from the wearer or for closing, putting on, opening or putting down the backpack or the sports or travel bag by means of at least one Tensioning element, the twist lock having a rotatably arranged tensioning roller for winding up the tensioning element, the tensioning roller being driven by means of an electric motor,
• a switching element that is connected to a controller, whereby the electric motor can be operated via the switching element and the controller,

The tensioning of the cap, jacket, trousers, hoodie, bra or belt on the wearer or relaxation of the same or the same from the wearer or the closing, putting on, opening or taking off of the backpack or sports or travel bag takes place by the User of the same or the same actuates the switching element, preferably with a finger.

The rotary fasteners mentioned are known for shoes. For example, consider the DE 298 17 003 U1 referenced, which discloses a shoe that works with an electromotive operated twist lock. Here a tensioning roller for winding up a tensioning element is driven by an electric motor so that the shoe can be laced and untied automatically. To lace up the shoe, the user operates an electrical switch and the electric motor of the twist lock is activated as long as the switch is pressed. Accordingly, the lacing force increases gradually. Once a desired level of lacing force has been reached, the user releases the switch. Another switch can be operated to unthread the shoe.

Accordingly, the lacing of the shoe takes a corresponding time during which the user has to press the switch. In addition, the respective desired lacing force level must be set by the user for each lacing.

Similar considerations also apply if an automated fastener is to be used that can be used on other items of clothing or items of luggage. Here, too, the task sometimes arises of putting on the item of clothing (for example in the form of a cap or jacket) or the item of luggage (for example in the form of a rucksack) and fixing it to the wearer's body with a predetermined tension level.

The US 2014/0257156 A1 discloses a medical device which can be placed on the wearer's body for limb support. The device is equipped with an electromotive clamping device. From the US 2014/0082963 A1 a sports shoe is known, which is provided with a motor-operated twist lock; this is connected to a mobile phone and can be controlled via this. Other solutions show that US 2008/0301919 A1 and the US 2015/0185764 A1 .

• Überstreichen der Oberfläche der berührungssensitiven Sensoren durch den Benutzer, vorzugsweise mit dem Finger, in eine erste Richtung,
• Detektieren des Signals der berührungssensitiven Sensoren von der Steuerung und Veranlassung des Anlegens der Mütze, der Jacke, der Hose, des Kapuzenpullis, des BHs oder des Gürtels an den Träger derselben oder desselben oder das Schließen oder Anlegen des getragenen Rucksacks oder der Sport- oder Reisetasche mit einem ersten Spannkraftniveau oder einem ersten Schließweg des Spannelements durch die Steuerung und den Elektromotor.

The invention is based on the object of developing a method of the type mentioned at the outset in such a way that generally putting on or taking off an item of clothing on the wearer or from the wearer or closing, putting on, opening or putting down an item of luggage carried by a person can be simplified. In particular, it should be possible to achieve this in a convenient and simple manner. It should be possible in particular to be able to adjust the putting on or taking off of the item of clothing or the closing, putting on, opening or putting down of the item of luggage to individual wishes in a user-friendly manner. In this way, it should be possible to put on the item of clothing or the item of luggage according to the user's wishes with a defined tension level without great operating effort. The solution to this problem by the invention is characterized in that the switching element has a number of touch-sensitive sensors arranged next to one another, which form a surface accessible to the user of the item of clothing or the item of luggage, the method comprising the steps:

• The user sweeps over the surface of the touch-sensitive sensors, preferably with his finger, in a first direction,
• Detecting the signal from the touch-sensitive sensors from the control and causing the hat, jacket, trousers, hoodie, bra or belt to be put on the wearer of the same or the same or the closing or putting on of the backpack or sports bag or travel bag being carried with a first clamping force level or a first closing path of the clamping element through the controller and the electric motor.

• Nochmaliges Überstreichen der Oberfläche der berührungssensitiven Sensoren durch den Benutzer, vorzugsweise mit dem Finger, in die erste Richtung,
• Detektieren des Signals der berührungssensitiven Sensoren von der Steuerung und Veranlassung des Anlegens der Mütze, der Jacke, der Hose, des Kapuzenpullis, des BHs oder des Gürtels an den Träger derselben oder desselben oder das Schließen oder Anlegen des getragenen Rucksacks oder der Sport- oder Reisetasche mit einem zweiten Spannkraftniveau oder einem zweiten Schließweg des Spannelements durch die Steuerung und den Elektromotor, wobei das zweite Spannkraftniveau höher ist als das erste Spannkraftniveau oder der zweite Schließweg größer ist als der erste Schließweg.

The method can further comprise the steps:

• Repeated sweeping over the surface of the touch-sensitive sensors by the user, preferably with his finger, in the first direction,
• Detecting the signal from the touch-sensitive sensors from the control and causing the hat, jacket, trousers, hoodie, bra or belt to be put on the wearer of the same or the same or the closing or putting on of the backpack or sports bag or travel bag being carried With a second clamping force level or a second closing path of the clamping element by the controller and the electric motor, the second clamping force level being higher than the first clamping force level or the second closing path being greater than the first closing path.

• Nochmaliges Überstreichen der Oberfläche der berührungssensitiven Sensoren durch den Benutzer, vorzugsweise mit dem Finger, in die erste Richtung,
• Detektieren des Signals der berührungssensitiven Sensoren von der Steuerung und Veranlassung des Anlegens der Mütze, der Jacke, der Hose, des Kapuzenpullis, des BHs oder des Gürtels an den Träger derselben oder desselben oder das Schließen oder Anlegen des getragenen Rucksacks oder der Sport- oder Reisetasche mit einem dritten Spannkraftniveau oder einem dritten Schließweg des Spannelements durch die Steuerung und den Elektromotor, wobei das dritte Spannkraftniveau höher ist als das zweite Spannkraftniveau oder der dritte Schließweg größer ist als der zweite Schließweg.

A second, higher clamping force level can thus be approached in a simple manner. This principle can also be continued: The method can further comprise the steps:

• Repeated sweeping over the surface of the touch-sensitive sensors by the user, preferably with his finger, in the first direction,
• Detecting the signal from the touch-sensitive sensors from the control and causing the hat, jacket, trousers, hoodie, bra or belt to be put on the wearer of the same or the same or the closing or putting on of the backpack or sports bag or travel bag being carried with a third clamping force level or a third closing path of the clamping element by the controller and the electric motor, the third clamping force level being higher than the second clamping force level or the third closing path being greater than the second closing path.

The touch-sensitive sensors can also be scanned further to further increase the clamping force level or the closing path. A clamping force level is preferred by Specification of the current with which the electric motor is operated is defined (see below).

• Überstreichen der Oberfläche der berührungssensitiven Sensoren durch den Benutzer, vorzugsweise mit dem Finger, in eine zweite Richtung, die der ersten Richtung entgegengesetzt ist,
• Detektieren des Signals der berührungssensitiven Sensoren von der Steuerung und Veranlassung des Entspannens des Spannelements auf ein reduziertes Spannkraftniveau oder auf einen reduzierten Schließweg durch die Steuerung und den Elektromotor.

The opening of the item of clothing or luggage or the reduction of the tension force level are preferably carried out by performing the following steps:

• Sweeping over the surface of the touch-sensitive sensors by the user, preferably with the finger, in a second direction which is opposite to the first direction,
• Detecting the signal from the touch-sensitive sensors from the control and initiating the relaxation of the clamping element to a reduced clamping force level or to a reduced closing path by the control and the electric motor.

For the completely relaxed end position, the tension pulley can be provided with a rotation angle sensor which is able to detect the zero position of the tension pulley.

The above-mentioned sweeping over the surface of the touch-sensitive sensors takes place according to a preferred procedure such that the user (preferably by means of a finger) sweeps over the sensors completely, ie over the entire extent of the surface of the sensors. In this way - as described - the clamping force level or the closing path can be increased gradually or in steps; in the same way (if the surface is swept over in the opposite direction) the tension force level can be reduced or the The item of clothing or luggage must be completely opened or prepared for storage.

However, it is also just as possible not to sweep over the surface of the touch-sensitive sensors completely, but only over part of their extension (with the finger). Depending on the length over which the user has swept over the surface, the control can send a (preferably proportional) signal to the electric motor so that the voltage increases accordingly or the closing path increases or (when swiping in the opposite direction) is reduced.

Thus, the proposed method allows a step-by-step closing (tensioning) and opening (relaxing) of the item of clothing or a step-by-step closing, putting on, opening or depositing of the piece of luggage that is carried by the person, including the surface of the touch-sensitive sensors completely or also is only partially covered in order to be able to fine-tune said tensioning or opening.

There is thus the possibility, by simply sweeping over the number of touch-sensitive sensors (in the first direction), to move to specifically defined tension force levels of the item of clothing or luggage and also to open the item of clothing or luggage, i.e. H. relaxation of the tensioning element by sweeping over the sensors once (in the second direction).

Tensioning and releasing or opening and closing are thus possible in a very simple and convenient manner.

A number of light-emitting elements, in particular in the form of light-emitting diodes (LED), can be arranged on or on the switching element, the current tension force level being indicated by the number of activated light-emitting elements. In this way, the user of the item of clothing or luggage can be shown in a simple manner how much the item of clothing or luggage is currently stretched on the body. The more LEDs light up, the more the item of clothing or luggage is taut. The opened state of the item of clothing or luggage can also be displayed via the LEDs.

The hat, jacket, pants, hoodie, bra, belt, rucksack or sports or travel bag with a twist lock and switch element can be characterized in that the switch element is formed by a number of touch-sensitive sensors arranged next to one another, the one Form surface accessible to the user of the item of clothing or luggage (in particular for a finger of the user). The common surface of the sensors is made as smooth and even as possible.

This is to be understood in such a way that the individual touch-sensitive sensors can be activated by swiping over the surface in order to generate the above-mentioned functionality.

The individual touch-sensitive sensors are preferably designed as capacitive sensors.

The individual touch-sensitive sensors are preferably positioned next to one another in a linear arrangement, with between three and seven touch-sensitive sensors preferably being arranged next to one another.

A number of light-emitting elements, in particular LEDs, are preferably arranged on or on the switching element.

According to a preferred embodiment, the switching element and the twist lock are arranged at different points on the said item of clothing or luggage. However, a combination with the twist lock to form a unit (consisting of a twist lock and switching element) is also possible.

As explained above, the user will usually sweep over the surface of the touch-sensitive sensors with his finger. However, this is not mandatory; In this regard, it can also be provided that an aid (e.g. a pen) is used to paint over it.

In the said item of clothing or luggage, spring means can be arranged which bias the said item of clothing or luggage into an open position against the action of the tensioning element. This means that after opening the twist lock, the item of clothing or luggage "folds open" into an open position and thus enables the item of clothing or luggage to be put on and taken off more easily.

For the energy supply, a rechargeable battery is preferably arranged in the item of clothing or luggage, which can be charged inductively or without contact. The battery that is required to operate the motor is in this case designed as a rechargeable battery and is supplied with a charging current via an induction coil. The ones for charging The electronics required can be placed directly on the battery. By providing an induction coil, the battery of the item of clothing or luggage can be charged without contact. For this purpose, the item of clothing or luggage can be placed on a corresponding charging plate and the battery can be charged. The LEDs mentioned above can also be used to indicate the charging or the charging status. For example, while the battery is charging, the LEDs can flash, with more and more LEDs flashing the more the battery is charged.

It can also be provided that the charge status of the battery is displayed by the LEDs while the item of clothing or luggage is in use. For example, it is possible for the LEDs to start flashing from a certain state of charge (e.g. when the battery has less than 50% of the maximum state of charge).

The proposed method and the explained locking system can be used particularly advantageously in the applications mentioned.

The touch-sensitive sensors discussed here are commercially available as such and are also referred to as “swipe sensors” or “touch panels”. It is generally a number (usually between three and seven) of sensors arranged next to one another, each of which is touch-sensitive, which enables the control to recognize through the sequence of the measured pulses of the individual sensors when swiping in the first or second direction, which measure (closing or opening / creating or storing) is to be carried out.

The first clamping force level is preferably defined by a first predetermined maximum current that the controller specifies for the electric motor during the clamping process; Said current is preferably between 1.1 A and 1.9 A. The second clamping force level is similarly preferably defined by a second predetermined maximum current that the controller specifies for the electric motor during the clamping process, the second maximum current being higher than the first maximum Electricity; Said current is preferably between 2.1 A and 2.9 A. The third clamping force level is correspondingly preferably defined by a third predetermined maximum current that the controller specifies for the electric motor during the clamping process, the third maximum current being higher than the second maximum current ; the current is preferably between 3.1 A and 3.9 A.

Said clamping force levels are thus defined by specifying a corresponding motor current (e.g. first level: 1.5 A - second level: 2.5 A - third level: 3.5 A) so that the motor is operated with corresponding maximum torques is, which in turn leads to a corresponding increasing tensile force in the tensioning element via the gearbox, which is preferably used between the motor and tensioning roller.

The tensioning elements are preferably tension wires. They can have polyamide or consist of this material.

Advantageously, the ease of use when using an item of clothing or luggage with an electromotive clamping system can be improved by means of a twist lock.

According to a further development of the item of clothing or luggage it can be provided that two tensioning elements are provided, which are simultaneously wound up by the tensioning roller and thus exert an even tensioning pressure on the body of the person who is wearing the item of clothing or luggage.

Of course, this configuration will not make sense in all of the applications mentioned. However, this can advantageously be used, for example, when putting on a rucksack, the two carrying straps of the rucksack then being tensioned simultaneously by two tensioning elements. The same applies to a jacket and trousers.

Both ends of the two tensioning elements are attached to the tensioning roller and each form a closed curve on two sides of the item of clothing or luggage. The two curves of the two tensioning elements can be designed essentially symmetrically to a central plane of the item of clothing or luggage.

The proposed method can also be further developed in such a way that a pressure sensor is arranged on or in the item of clothing or luggage, which detects the degree of tension of the item of clothing or luggage on the wearer's body. This pressure can be compared with a value that is stored in the controller. If too high a pressure is detected while the item of clothing or luggage is being worn, provision can be made for the control to autonomously cause the voltage to be reduced. Conversely, if the pressure is too low, the item of clothing or luggage can also be re-tensioned, which the controller does independently.

An exemplary embodiment of the invention is shown in the drawing. Show it:

Fig. 1

schematically in the side view of a partially sectioned cap that can be tightened with a twist lock on the wearer's head, and

Fig. 2

a perspective view of a switching element for actuating the twist lock by the finger of the person using the hat.

In Figure 1 a piece of clothing 1 can be seen in the form of a cap. The cap 1 is designed as a peaked cap; the screen is labeled 13. When the cap 1 is placed on the wearer's head (not shown), it can be tensioned with a desired tensioning force level on the wearer's head. A tensioning strap 12 is provided for this purpose. With conventional solutions, the tensioning strap is set by hand to a desired tensioning force level.

In the proposed solution, an electromotive solution is provided for this purpose: a twist lock 2, which has a tensioning roller 4, is integrated into the cap 1. The tensioning roller 4 tensions a tensioning element 3, which is connected to the tensioning band 12. An electric motor 5 actuates the tensioning roller 4 via a transmission (not shown). The electric motor 5 is controlled by a controller 7. A switching element 6 is provided for operating the rotary lock 2 (via the electric motor 5 and the controller 7).

In the exemplary embodiment, the switching element 6 is located in the front of the cap and is easily accessible by a finger of the user.

To tighten and loosen the tensioning strap 12 on the head of the wearer of the cap 1, the user proceeds as follows:
The switching element 6 has, as it is from Figure 2 can be seen, a surface 10 which is provided with a number of touch-sensitive sensors 9. Specifically, five touch-sensitive sensors 9 are arranged linearly next to one another in the present case. The individual touch-sensitive sensors 9 are designed as capacitive sensors which are known as such in the prior art. They respond to the contact being made with the finger 8 of the user of the cap 1.

To close the tensioning strap 12 of the cap 1, the user passes his finger 8 over the touch-sensitive sensors 9 in a first direction R1. If the controller 7 detects said contacting of the sensors 9, it causes a first clamping force level to be approached, i. H. the electric motor 5 is operated with a first, predetermined maximum value for the motor current, for example 1.5 A.

Luminous elements 11 in the form of LEDs are arranged on the switching element 6. By activating one or more of the lighting elements 11, the applied tension force level can be displayed to the user (which in the exemplary embodiment the user can only see in a mirror).

If the scanning of the sensors 9 with the finger 8 is repeated in the first direction R1, a second, higher clamping force level can be approached will; a second, specified maximum value for the motor current can now be 2.5 A, for example.

If the sensors 9 are passed over again, the clamping force level can be increased further; a third, specified maximum value for the motor current can now be 3.5 A, for example.

As a function of the translation between the motor 5 and the tensioning roller 4 and as a function of the geometric relationships up to the engagement of the tensioning element 3 on the tensioning band 12, corresponding tensioning force levels result.

The light elements 11 can in turn be used to display the current tension force level.

To open the tensioning strap 12, the user strokes the surface 10 with his finger 8, i. H. the touch-sensitive sensors 9, in a second direction R2, which is opposite to the first direction R1. The controller 7 then causes the tensioning strap 12 to open completely. The electric motor 5 then moves into the completely relaxed state, which can be determined by a corresponding angle of rotation sensor on the tensioning roller 4.

The user does not have to operate a closing or opening switch for a long time; it is sufficient to pass over the touch-sensitive sensors 9 in the manner described.

In this way, the user can advantageously select a clamping force level that suits his needs without having to set this by pressing the closing switch for a correspondingly long time.

The embodiment shows a cap. Of course, the proposed principle can also be used for many other applications.

For this purpose, items of clothing such as (sports) jackets and (sports) trousers, in which certain geometrical relationships are adjustable, for example the tension of the garment in the hip area or the length of the trouser legs and sleeves, may be mentioned. The automated raising or lowering of a hood is also conceivable for a (sports) jacket. The automated opening and closing of jackets can also be provided for jackets in particular. The embodiment explained can also be used very advantageously with a bra (brassiere).

Other particularly advantageous applications are rucksacks. The length of the shoulder straps can be adjusted here as described in order to be able to adapt the backpack to the needs of the wearer. Again, automated opening and closing can also be provided for this application. The same applies to bags, in particular to sports bags and travel bags, with these mostly only providing for automated opening and closing.

Another application is the integration of the device described in a belt, with which the (instep) length adjustment can then take place in the manner explained.
