Description

locking system

The invention relates to a closure system for a commodity, in particular items of clothing, bags, cases, panels, covers, as described in the preamble of claim 1.

WO 95/03720 A2 describes a generic closure system with a rotary closure arrangement and further refers to the closer formation thereof, as described in more detail in EP 0 412 290 A2. The closure system further comprises a closure piece and a tensioning element. The rotary closure assembly has a

Base part, a rotatably mounted on the base part clamping disc for winding and unwinding at least one held thereon tension element and a releasable latching unit for fixing the clamping disk in a made up and unwinding of the clamping disk. The latching unit has a manually operable actuating device with at least one actuating element. The release unit is triggered by an actuating force acting on the actuating element in the axial direction. A decrease in the rotary closure arrangement of the commodity is not provided.

WO 2014/059459 A1 describes a closure system for an article of daily use, with a zipper, a slide and a zipper grip, in which, in the closed position of the zipper, the zipper grip is guided at least partially through a closure piece formed or arranged on the article of daily use. The slider is kept positioned in this closed position on the commodity. Furthermore, at least one plate is arranged in the closed position of the zipper in the region of the closure piece. The plate is designed as an application element, in particular as a decorative object, art ornament, motif, stone, clothing accessory, and is fastened to the side facing away from the slider, ie on the outside of the utility object, on the closure piece. The closure piece is formed by a hollow profile-shaped base part.

From DE 195 43 758 Cl a trouser button with a mechanism incorporated in the housing for closing a zipper is known. The knob housing has a spiral spring. This coil spring is connected to a coil. About the coil is wound a string that emerges through an opening at the bottom of the button housing. At the bottom of the coil are in the winding direction of the string acting barbs, which engage in a connected to the knob housing perforated disc. The perforated disc is displaceable by compressing the entire knob to the rear. At the emerging from the button cord a hook for attaching the zipper guide is attached. When the zipper is opened, the cord unwinds from the spool and thereby tensions the coil spring. The barbs, however, the pulling force can not act on the zipper guide. By squeezing the button, the perforated disc moves backwards. The coil now rotates in the winding direction by the tensile force of the spiral spring, whereby the zipper closes. At the rear part of the knob, a thread for mounting the knob is embedded.

The present invention has for its object to provide a compact closure system with a rotary closure assembly, which closure system allows a more universal use with simple and safe operation.

This object of the invention can be achieved in that the rotary closure arrangement is held removably by means of a coupling arrangement on the closure piece, and the coupling arrangement comprises at least a first coupling element and at least one cooperating with the first coupling element second coupling element, wherein the first coupling element is arranged or formed on the closure piece in that the at least one actuating element of the actuating device is adjustable in a vertical direction with respect to an axis of rotation of the clamping disk, wherein both the second coupling element of the coupling arrangement and a first locking element of the latching unit are arranged or formed on the at least one actuating element, and in that at least one actuating element by means of an adjusting force acting thereon, starting from its non-actuated initial position after a first adjustment path into a first unlocking position and after a following In the first unlocking position, the first latching element of the latching unit is out of latching engagement with at least one second latching element arranged or formed on the clamping plate, and in the second unlocking position is the at least second latching element in the same unlocking position Coupling element of the coupling arrangement is brought out of engagement with the at least first coupling element on the closure piece. The advantage achieved in this way is that by means of the at least one actuating element and its relative possible adjustment into two different unlocking positions, the latching of the tensioning disk can be achieved when the first unlocking position is reached. This ensures that the wound on the tensioning pulley tension element can unwind so far that the preload built first loosens or is canceled at all. This only leads to an enlargement of the closed circumferential length of the closure system and still no separation of the same. This can be carried out, for example, in a sitting position, such as when driving a car, food or the like. A Weitenverstellung. Should the sitting posture be terminated, the user of the closure system only needs to shorten the effective length of the tension element accordingly by rotating the tension pulley and the associated winding thereof, whereby the entire closure system is tensioned again. For example, if the closure system is used in conjunction with a pair of trousers or a skirt, and the waistband should be opened wide enough to change the garment or remove it from the area of the hip to the legs to take a seated posture on a toilet an actuator first in the first unlocking position to reduce the bias of the tension member and in addition to spend even more in the second unlocked position. In this second unlocking position, the coupling connection between the rotary closure arrangement and the closure piece can then be released. If the decrease of the rotary closure arrangement is carried out by the closure piece, the collar and possibly the zipper or the button assembly can be opened. Then, the user can spend the garment from the area of the hip toward the legs. Since one end of the tension element is also held in an end region of the tensioning element, the uncoupled rotational closure arrangement also remains in operative connection with the tensioning element via the tension element and does not need to be stowed or stored separately. For the reverse process of putting on the garment, this is first to spend with the waistband in the area of the hip. Then the zipper or the button assembly and possibly the federal government to close. Subsequently, the rotary closure arrangement is to be coupled to the closure piece by means of the coupling arrangement. If this is done, the clamping disc can be rotated, which is shortened by the winding the effective length of the tension element and the desired width adjustment can be adjusted in the waistband. Furthermore, it may be advantageous if, when the actuating element is in the first unlocking position, the at least first and the at least second coupling elements are still in coupling engagement with each other. The two unlocking positions can be realized by means of a single actuating element for the actuation of the rotary closure arrangement. Since only the locking device with the cooperating first and second locking elements is unlocked after the adjustment in the first unlocked position, so that the clamping plate can be rotated or adjusted relative to the base part. Thus, the bias of the entire closure system can be reduced or even reduced. Furthermore, in the first unlocked position, the rotary closure arrangement still remains coupled to the closure piece.

Another embodiment is characterized in that the at least one actuating element guided in an aligned in the vertical direction with respect to the axis of rotation adjustment plane on the base part, in particular guided in a straight line, is. As a result, a space-saving and in the direction of the axis of rotation small overall height of the rotary closure arrangement can be realized. Another advantage is that thereby the risk of unintentional release of the latching unit or latching device can be avoided rather than would otherwise be the case with a releasable latching unit in the axial direction.

Another alternative embodiment is characterized in that arranged on the at least one actuating element or formed first locking element on that of

Clamping disk facing side and the second coupling element of the coupling arrangement is disposed on that side facing away from the clamping disk. By the opposing arrangement of the locking element and the coupling element, a clear separation between the two adjustment operations can be ensured to the two unlocked positions.

Another possible embodiment has the features that the base part is cap-shaped and has a hollow-cylindrical cap wall and a tensioning disk. having turned cover wall. This can be created on the base part for the clamping disk and the actuator each independent support or storage. In addition, as well as a high guiding and holding accuracy can be achieved. A further embodiment provides that on the top wall of the base part in the region of the axis of rotation in the direction of the clamping disc protruding trained bearing element is arranged or formed, and on which bearing element the clamping disk is rotatably mounted. Thus, an additional central bearing point can be created so as to avoid mutual tilting during the adjustment or clamping operation.

A further preferred embodiment is characterized in that in the top wall of the base part at least one opening is formed and the first latching element of the latching unit protrudes through the opening and projects beyond the top wall in the direction of the clamping disk. This creates the possibility, on the one hand to be able to properly guide the actuating elements in the base part for their transverse adjustment and, on the other hand, to nevertheless be able to create an engagement of the latching elements which are in operative connection with one another.

Furthermore, it may be advantageous if the at least one opening forms a longitudinal guide for the first latching element. This not only an even better longitudinal guide but also a lateral support of the breakthrough projecting, first locking elements can be created.

Another embodiment is characterized in that the at least one actuating element is adjustable at least along its first adjustment against a restoring force built by a spring element and is reset after the removal of the adjusting of the restoring force of the spring element in its unactuated initial position. This always ensures that the clamping disk can be kept in a locked position relative to the base part positioned. In addition, however, an unintentional decrease or release of the rotary closure arrangement from the closure piece is prevented. Another possible embodiment has the features that the first locking element is cylindrical. This has the advantage that such tilting during the transverse adjustment or radial adjustment of the first locking elements can be prevented. A further embodiment provides that the actuator comprises two mutually adjustable actuators, and to each of the actuators an actuator is arranged, wherein the actuators are arranged approximately diametrically opposite each other. As a result of the multiple arrangement of the actuating elements, an even safer and simpler operation of the rotary closure arrangement can be created.

Another embodiment is characterized in that the latching unit has a plurality of second latching elements arranged one behind the other in the starting direction, which second latching elements form a latching toothing, which latching toothing is located on the tensioning disk in the region of the rotational axis. As a result, a plurality of distributed over the circumference arranged locking positions can be created.

A further preferred embodiment is characterized in that the rotary closure arrangement has at least one application element on its side facing away from the base part. By arranging or providing the application element on the rotary closure arrangement, this can be adapted individually to the user and optically and creatively to the appearance of the garments.

Furthermore, it may be advantageous if a support element is arranged between the application element and the tensioning disc. Thus, an even higher variation possibility for the respective user can be created. In addition, however, as an additional protection for the application element can be created.

Another embodiment is characterized in that the at least one application element or the support element is preferably fixedly held on the base part. This prevents inadvertent adjustment of the clamping disk and beyond always a constant orientation of the application element can be maintained. Another possible embodiment has the features that the closure piece has a fastening arrangement for attachment to the commodity and a hollow cylindrical connector formed. By providing the hollow cylindrical connector formed a suitably trained zipper handle of the slider for positionally fixed support in the closed position of the zipper on the closure piece can be created.

A further embodiment provides that the clamping element has at its first end portion a coupling element attached thereto, with which coupling element, the first end of the tension element is in particular releasably connected. As a result, a circumferentially continuous closure system can be created, wherein additionally a simple coupling possibility between the tension element and the tensioning element can be created.

Another alternative embodiment is characterized in that the clamping element is strip-shaped or belt-shaped and is held at its second end region on the closure piece. As a result, a simple fastening possibility of the revolving clamping element in the region of its second end region in the region of the rotary closure arrangement can be created. A further preferred embodiment is characterized in that, in the section of its second end region, the tensioning element has a plurality of openings arranged one behind the other in the longitudinal extent thereof and arranged at a distance from one another, and the closure piece is accommodated in one of the openings. By providing the openings arranged one behind the other, it is thus easy to make a rough width adjustment and pre-adjustment by the user.

Furthermore, it may be advantageous if the closure system comprises a zipper with a slider and a zipper handle connected to the slider. As a result, an even higher possibility of combination with a wide variety of consumer goods, in particular items of clothing, can be created.

Finally, another embodiment may be characterized in that the zip fastener handle at least partially in the hollow cylindrical connector is included. Thus, in the closed state of the zipper unintentional opening of the same can be safely prevented. In addition, but also a more cost effective design of the slider itself can be achieved, since so can be dispensed with arranged in the slide locking mechanisms.

Another possible embodiment is also that the actuating device has an electromotive or an electromagnetic actuator. As an electromotive actuator can, for example, a DC motor can be used. It is advantageous to use a servomotor, since the determination and / or knowledge of the number of revolutions, the first and second adjustment can be determined or determined. As an electromagnetic actuator, for example, a two-stage acting / working solenoid is provided, in particular a solenoid. By means of two separate and separately controllable windings, or by means of a winding and control with two different high voltages, two different tightening paths and thus the first and second adjustment can be realized.

Accordingly, it is provided according to a development that the actuating device further comprises a control electronics, which is connected via a control output to the adjusting device. In order to realize the two adjustment paths, the control electronics can apply a voltage to the control output for a specific time in the case of an electric-motor actuating device. The duration is thus the determining factor for the number of revolutions of the shaft output. It is also possible that a voltage is applied and a feedback signal of the motor is evaluated, this feedback signal has a clear reference to the revolutions of the shaft output. In the same sense, it is also possible that a first adjustment path can be realized by applying a first electrical voltage to an electromagnetic actuator. By increasing the voltage to a second value, the second adjustment path is realized. Equally meaningful this also applies to an embodiment with as coils, wherein by applying the first coil with voltage of the first adjustment and by additional or alternative loading of the second coil with voltage of the second adjustment is realized.

An advantageous development is also that the control electronics has a communication interface, which for wireless communication with a communication Onsgegenstelle is formed, preferably by means of Bluetooth. With this development it is achieved that the actuating device can be addressed without a physical contact. This is in particular to the advantage that thus protection against direct access to the actuator can be realized. With regard to securing the closure, that is to say a protection against unauthorized opening, this is likewise advantageous since the actuating device can only be unlocked if the communication counterpart is in the range determined or determined by the wireless communication method. A development also consists in that the communication counterpart is designed as a mobile data terminal, for example, as a mobile phone, PDA, laptop, tablet, this list is not meant to be exhaustive. Such devices are now very widely used and belong to a variety of people for everyday use. Another advantage lies in the fact that such devices, due to their multi-functionality, provide processing capability as well as sufficient processing capacity to perform, for example, backup, encryption or access checks. Optionally, such systems also

With regard to a self-sufficient operation of the actuating device or the closure system, it is advantageous if the control electronics with an energy source and / or a

Energy storage is connected. Primary cells are used as the energy source, preferably Li-based batteries, since they have a very high energy density and a low self-discharge. As energy storage secondary cells are used. For charging of energy storage can be provided that the actuator has a charging port. With regard to an encapsulation of the actuator to protect against unauthorized access, it is also advantageous if the charging of the energy storage can be done wirelessly, for example. Via an induction loop.

Further developments also consist in that a shaft output designed for rotation of the electromotive adjusting device is connected to the actuating element via a pull or push rod gear, or that an actuating element of the electromagnetic adjusting device designed for linear movement is motion-connected to the actuating element, if necessary with the interposition of a deflection unit , To the first and second adjustment of the second coupling elements of the actuating elements to be able to realize with a rotational movement or with a linear movement, it may be necessary to implement the drive movement in the adjustment movement. For example, two threads can be arranged with opposite inclines in the shaft exit, in which engage the respective corresponding pull or push rods of the actuating elements. In one of the electromagnetic adjusting device, it may be necessary to divert the linear movement of the adjusting element in an opposite movement of the actuating elements, for example. Via a deflection bar or deflection device. With a further development, according to which the actuating device is arranged in a recess of the base part is achieved in an advantageous manner that a compact design is maintained and in particular the actuator is protected by the base part against unauthorized access. Respectively, a manipulation attempt is immediately recognizable. To secure the locking system and in particular the actuating device is provided according to a development that the actuating device or the adjusting device has a tamper-evident feature. This can for example be formed by a tear-off, which is irreversibly damaged when opening the closure system, both authorized and unauthorized. Thus, in particular, an unauthorized manipulation attempt can be clearly identified. For example, the tamper-evident feature may be located on the actuator and damaged by movement thereof.

A further development also consists in the fact that a further tension element is arranged on the second end region of the tensioning element, said tension element also being held on and unwound from the tensioning disk. With this development, a closure system is created in the rotary closure assembly and strap are separable. This has the advantage that the tension belt can be provided as a wearing part and can be easily replaced, and furthermore that the rotary closure arrangement is protected against damage when attaching the tensioning belt.

A further development consists in the fact that the clamping element is designed to be divided in its longitudinal extent between the two end regions, and wherein the two dividing ends are each firmly connected to the commodity. This enables a training training of prefabricated articles of daily use, in which the tensioning element, or the two sub-elements can be arranged firmly and at optimal use points on the object of daily use. Also, with this development, a manipulation attempt is suppressed, in which the entire clamping element is removed from the commodity in order to gain unauthorized access.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

In each case, in a highly simplified, schematic representation:

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.

In Figs. 1 to 4, a closure system 1 for a commodity, especially clothing, bags, cases, panels, covers, etc. is shown. The cover can be used, for example, as a boat cover, this form of cover is called a cover. For example, the garment may be trousers, be formed a skirt or the like. Usually, such garments are provided in the region of the waistband for dressing and undressing with an incision, which in turn can be closed by a person, for example, with a zipper, multiple buttons or the like.

In the present exemplary embodiment, the closure system 1 comprises a rotary closure arrangement 2, which in turn is held on a closure piece 3. The closure piece 3 can in turn be arranged on or attached to the article of daily use or it can be fastened thereto. The closure piece 3 can, as best seen in FIGS. 3 and 4, have a fastening arrangement 4 for attachment to the article of daily use. The attachment assembly 4 could be e.g. be formed by connectable parts of a riveted joint. Furthermore, it is possible that the closure piece 3 also has a hollow cylindrical connector 5 whose function will be described in more detail below.

Furthermore, the closure system 1 can also comprise a tensioning element 6 with a first end region 7 and a second end region 8 arranged at a distance from it in the longitudinal extent of the tensioning element 6. The tensioning element 6 can be designed, for example, in the form of a ribbon, a belt or a rope. Usually, the clamping element 6 is also referred to as a belt, tensioning cable or the like.

The rotary closure arrangement 2 in turn comprises a plurality of component components, wherein the most essential of a synopsis of Figs. 3 and 4 can be seen. For example, the rotary closure arrangement 2 can comprise a base part 9, a tensioning disk 10 rotatably mounted on the base part 9 and at least one tensioning element 11 held on the tensioning disk 10. The clamping disk 10 may also be referred to as a pulley. The tension element 11 can be wound up or unwound on the tensioning pulley 10 to change its effective length by turning the tensioning pulley 10. In most cases, the tension element 11 is designed to be loop-shaped or wire-shaped and can itself be formed from a very wide variety of materials or combinations of materials.

Furthermore, a releasable latching unit 12 is also provided, which for fixing the clamping disk 10 in an up and unwinding position of the clamping disk 10 serves. The latching unit 12 may further comprise an actuating device 13 with at least one actuating element 14.

As can be seen again from FIG. 1, a first end 15 of the tension element 11 can be held on the first end region 7 of the tensioning element 6 for circumferentially closing the closure system 1 and the subsequent tensioning operation. An unspecified and illustrated second end of the tension element 11 is optionally releasably held on the tensioning disc 10. The rotary closure arrangement 2 is held detachably on the closure piece 3 in this embodiment shown here by means of a coupling arrangement 16. For this purpose, the coupling arrangement 16 at least a first coupling element 17, which is arranged or formed on the closure piece 3. At least one further, second coupling element 18 is provided for cooperation with at least one first coupling element 17. The second coupling element 18 of the coupling arrangement 16 is arranged in the present embodiment on the at least one actuating element 14 of the actuating device 13. The first coupling element 17 may be formed, for example, by a disk-shaped body which has sections running parallel to one another on diametrically opposite sides. The one or more first coupling elements 17 may then be formed, for example, as a circular-shaped circular sections. But there would be other forms of space of the coupling or elements 17, 18 conceivable. The at least one first coupling element 17 is arranged or formed on the closure piece 3 on the side facing the rotary closure arrangement 2. The or the second coupling elements 18 of the coupling assembly 16 may be formed, for example, hook-shaped and engage over or engage behind the engagement or the first coupling elements 17 in the radial direction.

The latching unit 12 of the rotary closure arrangement 2, which can usually be triggered manually by a user, may for example comprise a first latching element 19, which in the present exemplary embodiment is likewise arranged or formed on the at least one actuating element 14 of the actuating device 13. Thus, both the second head pelelement 18 and the first latching element 19 is arranged or formed on the at least one first actuating element 14.

Furthermore, it is provided here that the at least one actuating element 14 of the actuating device 13 is preferably adjustable in a mostly vertical direction or a radial direction with respect to a rotation axis 20 of the clamping disk. The transverse adjustment of the at least one actuating element 14 with respect to the axis of rotation 20 may, for example, be rectilinear or curve-shaped in a plane or adjustment plane oriented perpendicular thereto with respect to the axis of rotation 20.

The latching unit 12 described above may in turn comprise a plurality of circumferentially successively arranged second latching elements 21, wherein the second latching elements 21 form a latching toothing in a known manner. The second locking elements 21 and the locking teeth formed by these is arranged or formed in the region of the axis of rotation 20 on the clamping plate 10 on the base part 9 or the at least one actuating element 14 facing side thereto. The first detent element 19, which interacts with the one or more second detent elements 21, may, for example, be cylindrical or bolt-shaped. The at least one actuating element 14 can, as has already been described above, in an adjustment direction oriented perpendicular or radial with respect to the axis of rotation 20 in an adjustment plane oriented perpendicularly to the axis of rotation 20 by means of an adjusting force acting on the actuating element 14, starting from its unactuated initial position a first adjustment travel can be spent in a first unlocked position. If the first unlocked position is reached, the first locking element 19 of the locking unit 12 is out of engagement with at least one of the second, arranged on the clamping plate 10 or second locking elements 21 By unlocking the detent position of the locking unit 12, the effective length of the tension element 11, for example further unwinding of the clamping plate 10, be enlarged or extended.

If the at least one actuating element 14 is moved or adjusted in a second unlocking position via a further second adjustment path in the same adjustment direction, is the at least second coupling element 18 of the coupling assembly 16 out of engagement with the at least one first coupling element 17 of the closure piece 3. If the coupling assembly 16 with its coupling elements 17, 18 disengaged, the entire rotary closure assembly 2 can be removed from the closure piece 3. If the at least one actuating element 14 is still in the first unlocking position, the at least first and the at least second coupling elements 17, 18 are still in coupling engagement with each other, whereby no removal of the rotary closure arrangement 2 from the closure piece 3 is possible, but only a width adjustment of the closure system is performed can be.

The base part 9 is cap-shaped in the present embodiment and has an approximately hollow cylinder-shaped cap wall 22 and a clamping plate 10 facing the top wall 23 or this is formed by the aforementioned components. Furthermore, additional guide webs 24 can be arranged or formed within the cap wall 22 on the top wall 23. At the one or more guide webs 24, for example, the at least one actuating element 14 may be performed in a plane aligned in the vertical direction with respect to the axis of rotation 20 on the base part. This guide can in particular be oriented in a straight line. In order to provide a certain security against rotation of the rotary closure arrangement 2 with its base part 9 on the closure piece 3, in particular its first coupling element 17, the previously described disk-shaped body with the lateral sections on the guide webs 24 can be supported in the circumferential direction. If the closure piece 3 also rotatably on the commodity, especially the garment arranged, can be achieved on this positive formation of the coupling elements 17 in cooperation with the guide webs or 24, a rotationally fixed mounting of the rotary closure arrangement.

Furthermore, it can still be seen from a synopsis of FIGS. 3 and 4 that the first detent element 19 arranged or formed on the at least one actuating element 14 is arranged on that side facing the tensioning disc 10. The second coupling element 18 of the coupling arrangement 16 is arranged on the at least one actuating element 14 on that side which is turned away from the tensioning disk 10 and thus facing the closure piece 3. The at least one actuating element 14 is, as already previously described, taken guided in the base part 9 and arranged on that side of the top wall 23, which is averted from the clamping plate 10. For receiving the at least one actuating element 14 corresponding recesses, openings or slots are provided in the circumferential cap wall 22.

To mount the clamping disk 10 on the base part 9 is still provided that on the top wall 23 of the base part 9 in the region of the rotation axis 20 in the direction of the clamping disk 10 protruding trained bearing element 25 is arranged or formed. The bearing element 25 can be formed either as a bearing journal or as a hollow cylindrical design. For storage of the clamping disk 10 on the bearing element 25 a corresponding bearing bore 26 is provided in this. Thus, the clamping disk 10 can be rotatably mounted on the base part 9.

Furthermore, at least one opening 27 may be formed or arranged in the top wall 23 of the base part 9. The at least one opening 27 is to be arranged such that the first latching element 19 of the latching unit 12 can penetrate through the opening 27 and further surmounted the top wall 23 in the direction of the clamping plate 10 so far that in the assembled state engagement of the first latching element 19 with the at least one second locking element 21 on the clamping plate 10 is possible. In this way, the at least one first catch element 19 also projects beyond the top wall 23 in the axial direction. The at least one breakthrough 27 can also be designed so that it forms an additional longitudinal guide for the first locking element 19.

In order to keep the at least one actuating element 14 in its unactuated initial position and, moreover, to adjust it back into the unactuated initial position after its adjustment along a previously described adjustment path, here the at least one actuating element 14 is assigned a spring element 28. The spring element 28 is shown schematically in Fig. 2 which is e.g. may be formed as a compression spring or the like.

If the at least one actuating element 14 is adjusted along its first displacement path, this takes place according to the arrow in the direction of the axis of rotation 20 against the restoring force built up by the at least one spring element 28. After the removal of the the at least one actuating element 14 applied adjusting force is automatically reset by the restoring force built up by the spring element 28, the at least one actuating element 14 in its unactuated initial position. Thus, an automatic re-locking of the tensioning disk 10 takes place by means of the locking elements 19, 21, which in turn are brought into latching engagement.

The arrangement of the at least one spring element 28 may be e.g. take place between the outside of the cap wall 22 and an actuating member 29 of the actuating element 14. However, it would also be possible, as indicated in dashed lines, to arrange the at least one spring element 28 within the cap wall 22 and to support the second coupling element 18.

Thus, it would be possible to use a circumferentially formed pressure ring made of an elastically deformable, automatically resettable material instead of the pressure spring indicated here.

Advantageously, the actuator 13 comprises two mutually adjustable actuators 14, wherein each of the actuators 14 each have their own actuator 29 is arranged or formed. The actuators 29 arranged and formed on the actuating elements 14 are preferably arranged such that they are approximately diametrically opposite one another. Thus, a simple succession-Zubewegung the two actuators 29 for the opposite adjustment of the actuators 14 to each other. This can be done for example by a simple joint movement between the thumb and forefinger. Due to the selected arrangement of the first locking elements 19 and the second coupling elements 18 each on the opposite side of the respective actuators 29 side with respect to the axis of rotation 20, is at an adjustment of the actuators 14, the radial distance between the axis of rotation 20 and the first locking elements 19 and the second Coupling elements 18 increases. But it would also be conceivable an opposite adjustment mechanism.

For axial retention of the clamping plate 10 on the base part 9 may serve a non-descript holder. In the region of the clamping disk 10, a plurality of first holding elements 37 arranged distributed over the circumference are provided on the side facing the base part 9. see which are preferably integrally connected to the clamping plate 10 and formed thereon. The first holding elements 37 protrude in the axial direction web-like from the clamping disk 10 on the base part 9 and engage with a radially inwardly projecting locking lug in a groove-shaped recess arranged on the outer circumference, which forms the second holding element 38. This can be seen from a synopsis of FIGS. 2 and 3.

For the design and / or decoration of the rotary closure arrangement 2, the latter can have at least one application element 30 on its side facing away from the base part 9. The application element 30 can be formed, for example, by a decorative object, an art ornament, a motif, a stone, a clothing accessory or the like. Preferably, the at least one application element 30 can be held or fastened interchangeably on the rotary closure arrangement 2, in particular the base part 9. In addition, however, it would still be possible for an additional support element 31 to be arranged between the application element 30 and the tensioning disk 10. The support element 31 itself can also form an application element and additionally serve as a holder or receptacle for the application element 30. In the present embodiment, the approximately disk-shaped application element 30 has a connection projection 32 in which, for example, a thread or the like is arranged. Thus, a screw connection between the application element 30 and the base part 9 can be provided. Preferably, the at least one application element 30 and / or the support element 31 on the base part 9 is fixed and thus not held rotatably.

As can be seen again from FIG. 1, the clamping element 6 can have at its first end region 7 a first coupling element 33 fastened or held thereto. At this first coupling element 33 or with this first coupling element 33, the first end 15 of the previously described tension element 11, in particular detachably, be connected or coupled. For this purpose, a unspecified second coupling element may be arranged or formed at the first end 15 of the tension element 11. In the embodiment shown here, the second coupling element is formed by a bolt or a pin. This makes it possible to replace the rotary closure arrangement 2 after decoupling the coupling arrangement 16 and the separation from the clamping element 6 against another rotary closure arrangement 2. The clamping element 6 may further be held in the region of its second end region 8 on the closure piece 3. For this purpose, in the section of its second end region 8, the tensioning element 6 can have a plurality of openings 34 arranged one behind the other in the longitudinal direction thereof and arranged at a distance from each other. For holding and fixing the circumferential width of the tensioning element 6, the closure piece 3 is then received in one of the openings 34. By providing a plurality of such openings 34, a coarse width adjustment of the clamping element 6 for the user can take place here.

As already described above, a slot or incision may be provided in the region of the waistband to increase the width of the waistband, which slot can be opened or in turn closed by a zipper which is not shown in detail but is well known. On the representation of the zipper was omitted in the figures.

In FIGS. 3 and 4, however, only one slider 35 of the zipper is shown, wherein this additionally comprises a zipper 36 connected to the slider 35, which may also be referred to as a slider handle. The zipper handle 36 may be formed, for example, bolt-shaped or peg-shaped and at least partially received in the hollow cylindrical connector 5 of the closure piece 3. Thus, in addition, the zipper can be prevented from unintentional opening, since the zipper handle 36 can thus be kept stationarily positioned on the closure piece 3.

To open the collar and the zipper, the rotary closure assembly 2 is first removed from the closure piece 3, in which case the zipper grip 36 can subsequently be removed from the closure piece 3 and the zipper can subsequently be opened.

In this embodiment shown here according to FIG. 1, the closure piece 3 is fastened to the outer part and thus to the overlapping part of the item of clothing which covers the zipper. After closing the zipper then the zipper handle 36 is inserted into the closure piece 3 and thus the federal government closed so far. Subsequently, the rotary closure arrangement 2 is to be fastened to the closure piece 3, which takes place via the coupling arrangement 16. The circumferential width of the closure system can be done by the rough presetting of the clamping element 6. If the first end 15 of the tension element 11 is also already connected to the first end region 7 of the tensioning element 6, the fine adjustment of the width adjustment of the closure system 1 can be carried out by rotating the tensioning disk 10.

The tensioning element 6 may e.g. arranged outside or in the form of a belt on the garment or worn. Another possibility, which may be independent, would be to receive the tensioning element 6 within the collar and to arrange only at least the first end area 7 for connection to the first end 15 of the tensioning element 11 outside the waistband. The second end region 8 of the tensioning element 6 is to be held in the region of the adjacent waistband section.

Another way to connect the waistband of the garment would still be to provide a conventional zipper arrangement and to have an opening in e.g. that portion of the garment which covers the zipper on the outside. to provide in the form of a buttonhole, and to attach the closure piece 3 to the underlying portion of the federal government. In this case, the slider 35 of the zipper can be formed in a conventionally known manner, since the zipper handle 36 can then no longer be brought into connection or coupling engagement with the closure piece 3. Thus, the slider 35 may have its own well-known opening assurance and the zipper handle 36 may be formed as a conventional slider handle in flat profile or rod shape. In this embodiment or embodiment, the closure piece 3 may be formed approximately knob-shaped and have at least one first coupling element 17 in order to perform the coupling described above with the rotary closure assembly 2 can. In this case, the closure piece 3 may comprise the fastening arrangement 4, an adjoining shaft part and, distanced from the fastening arrangement 4, the at least first coupling element 17. The at least one first coupling element 17 may project beyond the shaft part in the radial direction. The remaining arrangement and design of the closure system 1 can be maintained the same and the rotary closure assembly 2, the clamping element 6 and the closure piece 3 include.

In the case of a possible and optionally separate embodiment of the rotary closure arrangement 2, it can also be provided that the actuating device 13, in particular In particular, the at least one actuating element 14 itself, is formed lockable or is provided with a locking device not shown. This creates the possibility of protecting the rotary closure arrangement 2 in its pretensioned position, in particular a winding position of the tensioning disc 10, against unauthorized opening of the actuating device 13. Thus, the most diverse covers could be kept simply biased on the object to be covered not only by means of the closure system 1, but also be protected against unauthorized removal or unauthorized removal of the cover. FIG. 5 a shows a further possible embodiment, in which the actuating device 13 has an electromotive actuating device 39. The electromotive adjusting device 39 is designed for example as a motor, in particular as a servomotor or servo motor, and provides a rotary output at a shaft output 40. For driving or for controlling the electromotive adjusting device 39, the actuating device 13 furthermore has a control electronics 41, which is connected to the adjusting device 39 via a control output 42. For operation of the control electronics 41 and the adjusting device 39 is further provided that the control electronics 41 is connected to a power source 43 and / or an energy storage 44. The control electronics 41 further has a communication interface 45, which is preferably designed for wireless communication with a communication opposite party, not shown. Preferably, the communication interface 45 is designed as a Bluetooth interface, which has the particular advantage that Bluetooth is largely supported by mobile data terminals as a communication counterpart. As mobile Datenendge- device are communication devices or systems understood that provide in terms of their built-data technology and communication technology advantageously mobile data processing or a mobile data access. In particular, smartphones are mentioned here, since they can establish communication with a remote authentication service via a public cellular mobile radio network on the one hand and can transmit the result of this authentication via Bluetooth to the communication interface 45. In an exemplary embodiment 40, two threaded portions 46 may be arranged at the shaft outlet, wherein the threaded portions 46 have an opposite slope. In these threaded portions 46 engage corresponding thread segments of the train or

Push rods 47 of the respective actuating element 14 a. Upon a rotational movement of the shaft outlet 40, the actuating elements 14 and in particular the second coupling elements will move towards each other or away from each other and thus establish or release the latching engagement or the coupling engagement, as has already been described in the manual operation of the actuator. By controlling the adjusting device 39 for a certain time or for a certain number of revolutions of the shaft output 40, the first and second adjustment path can be realized on the basis of the knowledge of the pitch of the threaded portions 46.

FIG. 5 b shows a further possible embodiment of the actuating device 13 with an electromagnetic actuating device 39. To simplify the illustration, only the detailed view is shown in FIG. 5 b. All other features are shown in Fig. 5a. The adjusting device 39 has an adjusting element 48, which performs a linear movement in the longitudinal direction of the adjusting element 48 when the adjusting device is actuated by the control electronics 41. By specific control by means of two different high voltages or by selective control of two different electric windings of the

Control element, two different adjustment paths can be realized. As already described above for a rotational movement in FIG. 5a, it is also provided in this embodiment that the linear movement of the adjusting element 48, which acts on an actuating element 14, is converted into a counterbalancing linear movement, which acts on the second actuating element 14. This is done, for example, by interposing a deflection unit 49, wherein the holding points for the movement deflection, in particular the holding device for fixing a rotation axis 50 of the deflection unit 49, are not shown in FIG. 5b. The particular advantage of the embodiments according to FIGS. 5a and 5b is that the closure state of the subject closure system can be fixed via an external communication counterpart. In particular, a manual opening can therefore be prevented or, according to further embodiments, a feature of originality, a malfunctioning recognize a common opening attempt. By this embodiment, in particular a two- or three-factor authentication can be realized in which the closure is only released when the external communication partner is connected via the wireless communication link to the control electronics. A three-factor authentication is achieved if the external communication partner is connected via an additional data network with an authentication service in order to check the admissibility of an opening request. Thus, it can be checked when and also by whom the closure status of the subject closure system has been changed, or explicitly determine a release of the closure.

The embodiments show a possible embodiment of the closure system 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments of the same, but also various combinations of the individual embodiments are mutually possible and this variation possible due to the teaching of technical action by objective invention in the skill of working in this technical field expert.

Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

The task underlying the independent inventive solutions can be taken from the description. For the sake of order, it should finally be pointed out that for a better understanding of the construction of the closure system 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.
