• the object of the present invention is to provide a closure device which, on the one hand, permits a detachable connection of assemblies to one another, but on the other hand also allows the assemblies to be tensioned relative to one another.
• the second closure part has an actuating element with a first engagement device and a winding element arranged on the actuating element and rotatable for winding a tension element in a winding direction with a second engagement device.
• the first engagement device and the second engagement device are not engaged with each other in a release position, so that the winding element is rotatable relative to the actuating element.
• the first engagement device and the second engagement device can be brought into engagement with each other, so that in an engaged position, the winding element via the actuating element is rotatable.
• the first closure part also has a first toothing device and the second closure part has a second toothing device. The first toothing device and the second toothing device are in the closed position of the closure device engaged with each other such that the first closure part and the second closure part along the winding direction are held positively to each other.
• the closure device has two closure parts, which can be attached to one another along a closing direction and are held together in a closed position, so that assemblies associated with the closure parts are connected to one another via the closure parts and their hold and the assemblies are also detached from one another by separating the closure parts from one another can be.
• the second closure part has a winding element on which a tension element can be arranged.
• the winding element may, for example, have the form of a cylindrical roller and carry a winding groove in which the tension element can be accommodated. By rotating the winding element thus the tension element can be wound and thus tensioned.
• the first closure member may be disposed on a first assembly
• the second closure member may be connected via the tension member with a second assembly, wherein by winding the tension member on the winding element, the first assembly and the second assembly can be stretched to each other.

• the tension element may be, for example, a rope, a belt, a belt, a belt, a chain or an (electrically conductive) cable.
• the tension element can be fastened, for example, with two ends to the winding element, so that by twisting the winding element, the tension element can be wound with its two ends onto the winding element. It is also conceivable and possible, however, that only one end of the tension element is fastened to the winding element in order to wind this end only by turning the winding element. It is also conceivable and possible that an internal section of the tension element is arranged on the winding element in order to wind the tension element by turning the winding element. And it is conceivable that a plurality of different tension elements are arranged on the winding element and can be wound over the winding element.
• the actuating element and the winding element via engagement means with each other (releasably) operatively connected.
• This makes it possible, in particular when the closure device is in the closed position, to turn the winding element by actuating the actuating element so that a tension element arranged on the winding element can be wound onto the winding element.
• the first engagement means of the actuating element and the second engagement means of the winding element for this purpose are engaged, so that an actuating force transmitted from the actuating element to the winding element and the winding element is thus rotated together with the actuating element.
• the engagement means can be released from their engagement to allow relative movement between the actuator and the winding element. This allows, for example, when the closure device is opened, an independent rotation of the winding element relative to the actuating element, so that when the closure device is open, the tension element can be easily unwound from the winding element without, for example while the actuator must be rotated with. This can considerably simplify the operation of the closure device.
• the first engagement means and the second engagement means are preferably in the engaged position and are held in this engaged position.
• the actuating element and the winding element are thus operatively connected to each other, so that a rotation of the actuating element leads to a rotation of the winding element and thus an actuating force is introduced from the actuating element into the winding element.
• the engagement means may, in one embodiment, be such that in the engaged position, a rigid, resilient and bidirectional connection between the actuating element and the winding element is produced.
• the actuating element and the winding element are thus only in the winding direction and against the winding direction rotatable together.
• the engagement between the first engagement means and the second engagement means but also be such that actuating forces are transmitted in an adjustment of the actuating element in the winding direction to the winding element, a rotation of the actuating element against the winding direction but not to a rotation of the winding element leads, but the actuating element against the winding direction is independent of the winding element rotatable.
• one of the engagement means or both engagement means for example, have a sawtooth shape such that lock in engagement with a rotation of the actuating element in the winding direction, the engagement means to each other and thus the winding element is rotated together with the actuating element, with a rotation of the actuating element against the Winding direction, the engagement means, however, can slide over each other and in particular no (notable) force transmission via the engagement means.
• the engagement means are, for example, circumferentially attached to the closing direction on the one hand on the actuating element and on the other hand on the winding element.
• the engagement means are in this case formed on mutually facing surfaces of the actuating element and the winding element.
• the winding element can, for example, have a sawtooth-shaped toothing effecting the second engagement device, while the first engagement device of the actuation element is formed by a sequence of adjoining engagement openings, with which the sawtooth-shaped toothing of the winding element engages in the engaged position.
• the actuating element and the winding element for example, can be adjusted to one another axially along the closing direction.
• surfaces of the operating member and the winding member on which the engaging means are formed are axially spaced apart along the closing direction so that the engaging means are not engaged with each other.
• the surfaces are approximated to each other, so that there is an engagement between the engagement means.
• the actuating element and the winding element are spring-biased to each other, for example in the direction of the release position.
• a spring element for example in the form of a coil spring or in the form of a sprung on the actuating element or the winding element spring act, which causes a spring-mechanical bias between the actuating element and the winding element in the direction of the release position.
• the first closure part and the second closure part each have a toothing device, which in the closed position of the closure device a positive fit along the winding direction of the closure parts to each other hers inconvenience.
• a positive fit here means that at least certain forces acting between the closure parts along the winding direction can be positively supported and discharged without the closure parts being displaced relative to one another along the winding direction. Such a positive fit can exist in the winding direction and also against the winding direction. It is also conceivable and possible, however, for forces to be supported only in one direction, that is to say in the winding direction or counter to the winding direction.
• the positive-fit hold can be such that a movement of the second closure part in the closed position relative to the first closure part is locked against the winding direction and / or in the winding direction, ie the positive-locking stop does not readily, at least not without removing the second closure part can be overcome by the first closure part.
• the form-fitting hold can also be such that, when a certain limit torque, which depends on the geometry of the toothing devices, is exceeded, the form-fitting hold can be overcome, so that the second closure part is subjected to a force introduction with which the limit torque is exceeded first closure part can be rotated in the winding direction and / or counter to the winding direction.
• the second toothing device (of the second closure part) can in this case be arranged on the actuating element or the winding element. A positive retention in the closed position can thus be produced between the actuating element and the first closure part or between the winding element and the first closure part.
• a kind of freewheeling device can be provided, which allows the second closure part to be rotated to the first closure part in the winding direction, when the closure parts are attached to one another and thus are in the closed position, but block movement against the winding direction.
• the second toothing device of the second closure part slides over the first toothing device of the first closure part, so that a ratchet movement of the second closure part to the first closure part in the winding direction is possible.
• gear elements of the toothing devices engage with each other such that a movement is locked and the second closure part and thus also the winding element are held in its currently occupied position.
• the toothing devices can, for example, engage with one another in the axial direction. Upon a rotation of the second closure part in the winding direction to the first closure part, the toothing devices slide over one another, For example, by sawtooth-shaped gear elements slide on each other. If the first closure part and the second closure part are mounted rotatably to one another and guided axially against one another, this can be accompanied by a (minor) axial movement of the second closure part to the first closure part.
• At least one of the toothing devices has at least one toothed element which can be pushed aside when the second closure part is rotated in the winding direction, for example transversely to the winding direction.
• This may be particularly useful when the first closure member and the second closure member are mechanically locked together in the closed position and can not be moved axially against each other.
• the first closure part has a cylinder portion which engages in the closed position in an opening of the winding element for rotatably supporting the winding element on the first closure part.
• the first toothing device of the first closure part can be circumferentially extended around the surface section.
• a rotatable mounting of the second closure part, in particular of the winding element of the second closure part, on the first closure part is effected via the cylinder section, so that the second closure part can be rotated by actuation of the actuating element in a simple manner, for example for winding the tension element onto the winding element when sliding over the toothing devices of the first closure part and the second closure part.
• a closure device of the type described here can be designed as a purely mechanical closure device, in which the closure parts are attached to one another and are mechanically held together in the closed position.
• shear forces in a plane transverse to the closing direction can be received by way of such a mechanical hold and, if appropriate, also, in the case of a mechanical latching between the closure parts, forces against the closing direction.
• the closure device is magnetically formed.
• the first closure part and the second closure part each have at least one magnetic element which, when the closure parts are attached to one another, is magnetically attractive to closing the closure device and thus magnetically supports closing of the closure device.
• a magnetic element may in this case be formed by a permanent magnet or by a magnetic armature, for example of a ferromagnetic material.
• one of the closure parts may have a permanent magnet which interacts magnetically attractively with a magnetic armature of the other closure part. It is also conceivable, however, that both closure parts each have a permanent magnet or an arrangement of a plurality of permanent magnets, which face each other when attaching the closure parts with unlike poles and thus support a piecing by magnetic attraction.
• the toothing devices of the closure parts can be engaged with each other, so that in the closed position there is an engagement between the toothing devices.
• it can also be brought about via the magnetic elements that the engagement devices of the actuating element and of the winding element are engaged with one another in the closed position.
• a magnetic element which cooperates with an associated magnetic element on the first closure part upon closure of the closure device. Due to the magnetic attraction force can be made in the closed position, the engagement between the engagement means of the actuating element and the winding element by the actuator is pulled towards the winding element due to the magnetic effect on the actuating element.
• the magnetic attraction force in the closed position preferably exceeds the biasing spring force, so that due to the magnetic attraction of the engagement between the Engagement means of the actuating element and the winding element can be produced.
• the first closure part and the second closure part can, in one embodiment, be locked together mechanically in the closed position for holding the closure parts against the closing direction, in the case of a magnetic or non-magnetic configuration of the closure device.
• one of the closure parts for example, a locking device having at least one adjustable locking element which engages in a latched position in a latching engagement of the other closure part and thereby holds the closure parts against the closing direction to each other.
• the latching device By means of the latching device, a mechanical latching between the closure parts is thus produced when the closure parts are attached to one another.
• the latching device the closure parts are held against one another counter to a load directed against the closing direction, so that a removal of the closure parts from each other is not possible without releasing the latching.
• the latching device When the closure parts are attached, the latching device preferably automatically reaches one another in the latched position. When the closure parts are attached to one another, the closure parts thus engage automatically with one another, so that the hold of the closure parts is secured together in the closed position.
• the second closure part may in this case optionally be rotatable in spite of the latching in the winding direction to the first closure part, so that the tension element can be wound onto the winding element when the closure parts are attached to one another.
• the latching device may have one or more latching elements. These are, for example, spring-biased in the direction of their latched position, so that the latching elements, when the closure parts are attached to each other, preferably engage automatically with the associated latching engagement of the other closure part.
• the latching device has an engagement element which engages in the closed position in the other closure part and on which the at least one latching element is arranged. If the latching device is arranged, for example, on the second closure part, the engagement element engages in the closed position into an associated opening, for example in a cylinder section of the first closure part which supports the winding element. One or more latching elements are arranged on the engagement element, so that the latching between the closure parts in the closed position is produced via the engagement element. In one embodiment, when the latching device is formed on the second closure part, the engagement element is axially adjustable along the closing direction to the actuating element.
• the actuating element can thus be displaced axially by a certain distance to the engagement element, which in particular makes it possible for the second closure part to execute a compensating axial relative movement to the first closure part when twisted to the first closure part and when the toothing devices slide over one another, if there is locking between the two second closure part and the first closure part.
• the engagement element is preferably spring biased relative to the actuating element, for example via a compression spring, which presses the actuating element and thus also the winding element in the direction of the first closure part, when the closure device is in the closed position.
• the latching device In order to release the latching between the closure parts and to be able to separate the closure parts from one another for opening the closure device, the latching device preferably has an operating element which can be actuated in order to disengage the at least one latching element from the latching engagement.
• an operating element which can be actuated in order to disengage the at least one latching element from the latching engagement.
• a user can press on the control element, which is arranged to be adjustable on the engagement element, in order to move or at least release the latching elements arranged on the engagement element, so that the latching of the latching device can be released.
• the operating element is guided, for example, axially along the closing direction on the engagement element.
• the engagement element may for example be designed as a socket, within which the control element is slidably received axially along the closing direction.
• a transmission for example a planetary gear, may be provided between the actuating element and the winding element, so that a force is introduced from the actuating element into the winding element via a gear and thus in a staggered or translated manner.
• the actuation of the actuator can be done manually by turning the actuator.
• Such an electric motor can, for example, at one with the first closure part connected assembly can be arranged stationary and can, for example, via a suitable transmission element, for example a drive worm, engage with a toothing of the actuating element, when the closure device is in its closed position.
• a suitable transmission element for example a drive worm
• one or more electrical contact elements may be arranged on the first closure part and on the second closure part, so that an electrical contact between the closure parts is produced when the closure device is closed.

• the winch output element can for example be freely rotatable relative to the winding element and / or the actuating element and guides the tension element with respect to the winding element, so that the tension element runs into the winding element in a defined manner. This prevents uncontrolled unwinding of the tension element from the winding element and in particular a knotting of the tension element during unwinding.
• the closure device described here enables a detachable connection of closure parts in combination with a tensioning possibility for a tension element. This makes it possible, for example, to bias the pulling element to train in the case of separate closure parts in order then to close the closure device and, in the closed position of the closure device, to wind and retighten the tension element by turning the winding element.

• the shutter device 1 is for fixing an article 5, for example, a cellular phone or the like, to a bicycle, particularly a handlebar of a bicycle.
• the tension element 4 is here wrapped around the article 5 and can be stretched by winding in sections on the winding element 35 of the closure part 3.
• Fig. 50 shows another embodiment with different winding of the tension member 4 for fixing an article 5, for example a mobile phone, to a bicycle.
• the shutter device 1 serves to fix an object, for example, a luggage, in a loading space of a vehicle.
• the tension element 4 is in this case laid over the luggage piece and holds in this way the luggage stationary at the bottom of the cargo space.
• the tension element 4 can be tightened for attaching the luggage.
• FIGS. 52 to 56 show a further embodiment of a closure device 1, in which closure parts 2, 3 can be attached to one another along a closing direction X and are held together in a closed position.
• the tension element 4 is designed as a belt, which can be wound onto a winding element 35 in the form of a sleeve of the closure part 3.
• the closure part 3 can be attached to the closure part 2, which has, for example, a belt buckle, so that ends of the tension element 4 can be connected to one another via the closure device 1 and tensioned relative to one another.
• the closure part 3 has an actuating element 34 with a hand lever formed thereon, which can be brought into engagement with an engagement device 355 of the winding element 35 via an engagement device 345, so that the winding element 35 is rotated in a winding direction V with respect to the closure part 2 via the actuating element 34 can.
• the actuating element 34 has a pin 346 with an engagement opening 347, with which the actuating element 34 can be placed in the closing direction X on a cylinder section 201 on a body 20 of the closure part 2 in order to fit the Closing parts 2, 3 to connect with each other.
• the engagement means 345, 355 are not engaged with each other when the closure members 2, 3 are separated from each other.
• the winding element 35 can thus be rotated freely relative to the actuating element 34, so that the tension element 4 can be unwound, for example, from the winding element 35.
• the closure part 3 is attached to the closure part 3 in such a way that the engagement opening 347 on the journal 346 of the actuating element 34 engages with the cylinder section 201 of the closure part 2, the winding element 35 being supported on the body 20 of the closure part 2 and due to a magnetic attraction of magnetic elements 23, 33 on the cylinder portion 201 on the one hand and the pin 346 of the actuating element 34 on the other hand (see Fig. 56) pulled the actuator 34 toward the winding element 35 and thereby engage the engaging means 345, 355 form-fitting with each other.
• the winding element 35 has a toothing device 351 in the form of a sawtooth-shaped toothing, which engages with a toothing device 25 on the body 20 when the closure parts 2, 3 are connected to one another.
• the engagement of the toothing means 25, 351 causes the closure parts 2, 3 can be rotated in the winding direction V to each other to tension the tension element 4 on the winding element 35, but not opposite to the winding direction V.
• the closure parts 2, 3 can be withdrawn from one another in the opposite direction to the closing direction X, so that in this way the closure parts 2, 3 are separated from one another.
• Figures 57A and 57B show the closure device 1 with separate closure parts 2, 3 ( Figure 57A) and with the closure device 1 closed ( Figure 57B).
• the closure device 1 can serve, for example, for tensioning a belt in the form of a belt.
• closure device 58 shows a further embodiment of a closure device 1, in which closure parts 2, 3 can be attached to one another in a closing direction X, analogous to what has been described above.
• a gear 26 is provided on the closure part 2, which may, for example, have the shape of a bevel gear or worm gear and serves, via the toothing device 25 (the closure parts 2, 3 connected to the toothing device 351 of the closure part 3 is engaged, as can be seen, for example, from Fig. 52) to rotate the closure member 3 relative to the closure member 2, so as to tension the tension member 4.
• the closure parts 2, 3 are thus rotated relative to one another via a gear provided on the closure part 2, which can be actuated manually, for example.
• 59 to 62A, 62B show a further embodiment in which just such a gear 26 is implemented for tensioning the winding element 35.
• the transmission 26 is formed in the embodiment according to FIGS. 59 to 62 A, 62 B as a tensioning gear, in which a tensioning lever 260 about a pivot axis 265th mounted pivotably on the body 20 of the closure part 2 and biased by a spring element 261 relative to the body 20 in a basic position (shown in Fig. 62A, 62B).
• the closure member 3 can be placed with a winding element 35 on a cylinder portion 201 of the body 20 and engages, in the connected position, via a toothing device 351 with an associated toothing device 25 of the body 20, as has also been described above.
• a clamping engagement 356 is formed in the form of a toothing, which rotates about the winding element 35 and serves to interact with the gear 26.
• An engagement lever 262 which serves to engage in the clamping engagement 356 of the winding element 35, is arranged on the tensioning lever 260 of the transmission 26, pivotable about a pivot axis 263.
• the tensioning lever 260 As shown in Fig. 61 A, 61 B, are deflected from the basic position in a pivoting direction P1, in this way to remove the engagement lever 262 from a range the winding element 35 in interconnected closure parts 2, 3 occupies.
• the closure parts 2, 3 can thus be readily attached to each other without interference from the transmission 26.
• the clamping takes place step by step. Due to the spring element 261 and the spring preload provided thereby, the tensioning lever 260 is automatically returned to an operating position in the basic position, the engagement lever 262 over the clamping engagement 356 away, under elastic deflection of the spring element 264, via which the engagement lever 262 to the tensioning lever 260 elastic is biased. The tensioning of the tension element 4 is thus effected stepwise by repeated actuation of the tensioning lever 260.
• a freewheel is provided about the spring element 264.
• the winding element 35 can also be twisted by hand in the winding direction V. In this case, the engagement 262 slides under elastic deflection of the spring element 264 via the clamping engagement 356 of the winding element 35.
• a closure device of the type described here can be used in very different applications.
• a closure device of the type described here a clamping device is combined with separable closure parts, which allows a connection of assemblies while simultaneously stressing the assemblies to each other.
