Device for winding a cable

The invention relates to a device for winding a cable, comprising a coil, which has a winding core and a receptacle for transmitting a rotational movement of the coil to the cable, a base body, to which the coil is rotatably mounted, and

a spring arranged in the winding core, which is connected in a spring-force-transmitting manner with the coil and the base body. Portable electrical appliances, be they mobile phones, tablet PCs or laptops, have become indispensable in everyday life. Especially mobile phones often need to be charged daily, which is why their charging cables are often in use. To store these, the cables are in drawers or

Collected storage containers, where they knot easily. Some people wrap charging cables manually, which often leads to cable breaks.

Many people also use headphones every day, whose cables have to be unraveled regularly before use. Furthermore, there are a variety of other cables in daily use, which are often in use and their handling causes trouble. Some cables are supplied by the manufacturer with automatic (spring-operated) cable reels. Such a cable winder is z. B. from US 2007/0295850 A1. Such cable reels have in a winding core a spring (a spiral spring with torque loading, often called "mainspring"), which is stretched when rolling out the cable to rewind the cable when relaxing the spring These cable reels are structurally designed so that the Cable from

Users can not be changed without considerable effort. In addition, the cable in the area where it emerges from the winding core, kinked when rolling around 180 ⁰ , which can quickly lead to breakage of the cable.

The invention is therefore an object of the invention to provide a device for winding a cable available, which prevents cable break despite compact design.

This object is achieved by a device for winding a cable with

a spool having a winding core and a receptacle for transmitting a rotational movement of the

Coil on the cable,

- A basic body to which the coil is rotatably mounted, and

a spring arranged in the winding core, which is spring-force-transmitting with the coil and the

Basic body is connected.

Characteristic is provided that the spring is arranged in an axial direction of the coil between the receptacle and the base body. The fact that the spring is arranged in the axial direction of the coil between the receptacle and the base body, the recording is much more space for gentle deflection of the cable available. A cable inserted into the device is thus guided by the receptacle so that the spring is arranged in an axial direction of the coil between the cable and the main body, that is, the cable extends beyond a side of the spring facing away from the main body. Thus, the receptacle may extend beyond an end face of the winding core facing away from the main body. Preferably, at least one entire, the base body facing away from the end face of

Winding core can be used for a cable-friendly configured geometry of the recording.

In particular, the receptacle is integrated in the winding core, so that an inserted cable emerges from the winding core. The inventive device thus a particularly compact cable winder (cable winder) was created, which spares an inserted cable during winding.

Because the receptacle is no longer arranged radially outside the spring in contrast to the prior art, relatively large bending radii of the cable are made possible within the receptacle, so that the cable is not kinked when it leaves the receptacle. So far were wide

Bend radii not practical, since in (relative to a rotation axis of the coil) radially outside of the spring arranged recordings increases with an increase in the bending radius of the diameter of the coil by twice the amount. In order to enable an approximately cylindrical winding core at a radially outside the spring arranged receptacle, in addition, an outer boundary for the spring was arranged eccentrically to make room for the inclusion within the winding core.

Due to the inventive arrangement of the recording on the side facing away from the base body of the spring, the spring can be arranged centrally. Thus, a portable (portable) device for spring-driven (automatic) winding of a cable is given. Characterized in that the receptacle is thus arranged on the side facing away from the base of the spring, thus a construction of a cable reel is provided, which in principle allows a user to insert even a cable in the device. Preferably, the device is designed so that a cable can be inserted by a user (non-destructive) into the device and / or exchangeable. Alternatively, however, the device may also be designed so that a cable is not interchangeable by the user (non-destructive).

In a typical use of the device, the main body does not rotate as a whole. However, it turns the coil relative to the main body. The main body can be plate-shaped and / or trough-shaped, or have such a region. In particular, the base body extends substantially in a radial direction of the coil, that is approximately parallel to an end face of the coil facing the base body, as a result of which the base body is designed in a particularly space-saving manner.

When winding the cable this is wound on the winding core of the rotating relative to the main body coil. In particular, a middle region of the cable is in the receptacle

so that the cable is pulled into the device on both sides of the central area and wound up on the winding core. The coil is rotatably mounted to the main body (ie, for example, in or on the base body).

Preferably, the device has a shaft or axis. The shaft is connected to the base torque transmitting, or an integral part of the body. Preferably, the spool is rotatably mounted on the shaft or the axis of the device.

The spring (ie that part of the spring which, when the spool is rotated, opposes the spool

Aufwickeldrehrichtung is deformed for energy storage), which in particular a coil spring (that is, a resilient coil on torque) is disposed in the winding core. The spring is arranged such that it is tensioned counter to a take-up rotation direction of the spool, that is to say in an unwinding direction of the spool. Thus, the spring relaxes in the winding rotation direction, whereby the spring allows the rotation of the coil and a winding of the cable. The spiral spring can also be referred to as a newly wound spiral spring, which is made of a spiral wound in a plane metal band (ie a mainspring). One end of the spring (in particular an outer end of the spiral spring) is connected with the coil, in particular with the winding core, so as to transmit spring force, while another end of the spring (in particular an inner end of the spiral spring) is connected in a spring-force-transmitting manner to the main body. Federerkraftübertragend means in this context that the spring is connected to the main body and the coil such that a spring force of the spring on the main body and the coil can be applied. The spring is preferably connected to the main body so as to transmit spring force, by being connected to the already mentioned shaft in a spring-force-transmitting manner, e.g. B. suspended in the shaft or hooked. The coil may nevertheless be mounted directly on the base body (for example on a projection of the main body) or alternatively also on the shaft.

In particular, the spring is so spring force transmitting connected to the main body and / or the coil, that when the coil is rotated in the unloaded state of the spring further in the Aufwickeldrehrichtung the coil, the spring to the main body and / or the coil is rotatable (stored). Thus, over-rotation of the spring, for example, when a user attempts to rotate the spool further than provided by the spring in the take-up rotation direction, is prevented. It is thus given the function of a freewheel, which locks against the Aufwickeldrehrichtung upon rotation of the spool.

The cable may in particular be a cable of a charger, headphone or earphone. Especially with such cables, there is a great need for a compact, spring-operated device for winding the cable. The receptacle, which can also be referred to as a driver, is in particular a (preferably groove-shaped) depression, as a result of which a particularly simple receptacle is created. The recess is open in particular to the side facing away from the base body. Thus, the rotational movement of the coil can be transmitted by means of a positive connection to the cable, so be pulled on the cable.

In particular, the receptacle extends transversely to the axial direction of the coil, in particular in a direction perpendicular to the axial direction extending plane. Because the cable emerging from the receptacle on both sides is resisting winding (for example because it is held by the user) on both sides of the cable, it does not slip out of the receptacle during winding, but is taken by the inclusion form-fitting. In addition, the cable is frictionally held within the receptacle by the rotation of the recording during winding. However, the cable is typically not pinched by the receptacle. It is particularly preferred that the recording by the (kinematic and / or

geometric) axis of rotation of the coil extends and / or the receptacle is adapted to guide the cable through this axis of rotation. By this configuration, the same amount of space for a cable gentle deflection of the cable is available on both sides of the recording. The recording can also be a multipart recording (or be referred to as such), whose parts z. B. outside a region of the axis of rotation of the coil are arranged.

The axial direction of the coil denotes the direction (independent of the sign) in which a (kinematic) axis of rotation of the coil extends. The radial direction indicates any direction as long as it is perpendicular to the axis of rotation of the spool or to the rotation axis. The radial direction of the coil thus runs at right angles to the axial direction.

Preferably, the receptacle protrudes into the winding core. As a result, an inserted in the receptacle cable from a radially outer boundary of the winding core (the winding surface) from the receptacle and thus the winding core, whereby a particularly space-saving arrangement of the recording is achieved. It is preferably provided that the recess less than 50%, preferably less than 40%, more preferably less than 33% of an axial length of the winding core (ie an axial

Extension of the hub) takes. Due to the fact that the receptacle occupies only a small part of the axial length of the winding core, more space for the spring remains inside the coil. Surprisingly, it has been found that even if the receptacle does not protrude at least into the middle of the winding core, or the receptacle is arranged only at the edge of the winding core, the cable is still neatly wound on the winding core. This can be done, for example, by manual guidance of the cable or below, advantageously designed guide window. Furthermore, it has been found that when the cable is wound up by the spring in which the cable is not held by the user, the dynamic movements of the cable mean that the cable will be stretched over the entire axial length of the winding core and not just around the winding core wraps.

The coil is rotatably held in particular on the base body, z. b. rotatably mounted on the base body. It is preferably provided that the coil is held rotatably on the base body by means of a positive connection. Due to the positive connection movement of the coil is prevented in the direction away from the main body, the axial direction of the coil.

Preferably, the positive connection between the spring and the base body is arranged. This allows a particularly space-saving and stable device. In addition, a distance between the positive connection and the base body is thereby minimized, which causes an increased rigidity. Due to the increased stiffness is a smooth running of the coil and a mechanical

Resistance of the device to external influences increased. In a preferred Arrangement of a locking mechanism between the coil and the base body is also the

Reliability of the locking mechanism increases because elastic deformations are reduced within the device. In addition, a part of the preferred shaft, which is arranged on a side facing away from the base body of the positive connection, and the spring with the main body connects (see above) are made relatively thin to provide more space in the winding core for the spring, while a part of the shaft between the positive connection and the base body can be made relatively thick to survive even high, acting on the outside of the coil forces unscathed. The positive connection can be realized for example by means of a shaft shoulder, by means of retaining lugs, or by means of a circumferential thickening of the shaft, which can be arranged on a side facing away from the base body of a arranged between the spring and the main body part of the coil. Furthermore, an annular boundary can be arranged on the shaft and connected to the shaft (immovable) (eg glued, pressed, or also positively connected). The annular boundary in turn provides the positive connection between the

Base body and the coil forth.

Preferably, the device has at least one guide window for feeding the cable to the winding core during winding of the cable. According to a preferred embodiment of the invention, it is provided that the device has two guide windows for feeding the cable to the winding core during winding of the cable, and the guide windows in particular have openings for insertion of the cable. The two guide windows are arranged in particular on opposite (radially outer) sides of the coil. The guide windows can be immovably connected to the main body, or be an integral part of the body. In particular, the collar

Guide window in the axial direction of the coil on a side facing the coil of

Basic body. Through the openings, the cable can be inserted laterally (ie not in a cable longitudinal direction) in the guide window. Through the guide window, an influence of an eccentrically arranged in the axial direction recording can be compensated. Preferably, the two guide windows to each other on an offset in the axial direction. Particularly preferably, a sliding region of a guide window arranged furthest forward in the cable winding rotation direction is inclined toward the base body. The sliding area thus does not extend in the axial direction, but faces the main body. Characterized in that a torque applied by the spring to the coil and the base body is supported by the sliding portions of the cable, the cable slides independently during winding in the direction of the body. Further preferably, a sliding region of the other guide window arranged furthest forward in the cable winding rotation direction is inclined away from the base body. The sliding area thus points away from the main body, whereby the cable automatically slides away from the main body. The openings of the guide windows are arranged in particular on the side facing away from the base body of the guide window, whereby they are easily accessible to a user. Instead of a sliding region, it is also preferable to use a roller so that the cable no longer slides over the sliding area but essentially adheres to the roller and rotates about a roller axis during winding and unwinding. The roller axis can be inclined like the sliding areas described above. But the roller axis can also run in particular parallel to the axis of rotation of the coil. The two roles of the two guide windows can be like that

Sliding areas have inclinations, so that the rollers have a tapered area. At The roller may have a flange at that end of the smaller diameter tapered portion of the roller. Thus, the cable from the tapered portion is not pressed against the housing (or a lid) but against the flange, thereby further reducing friction on the cable.

In particular, both guide windows each have at least one roller.

Preferably, it is provided that the coil comprises at least two retaining projections for holding the cable on the winding core, wherein the retaining projections on a side facing away from the base body of the winding core of the winding core transversely to the axial direction (in particular in the radial direction) of the coil and between the retaining projections at least two recesses are provided for inserting the cable. The term "across one direction" means "a direction different from the direction". The retaining projections extend in particular in the radial direction of the coil. The two retaining projections can be considered together as a doubly interrupted end flange of the coil. The recesses between the retaining projections can be regarded as a free distance between the retaining projections. In particular, the recesses are elongated recesses. A cable exiting the receptacle may be routed through the recesses into the interior of the spool (into a reel spool space) and subsequently to the guide windows. Of the retaining projections a rolled up on the winding core cable is held on the winding core and within the device. The two recesses can be supplemented by the inclusion to a continuous recess.

Further preferably, the device (in particular the coil) also has a particular circulating Aufwickelraumbegrenzung on a side facing the base body (ie a the

Retaining projections opposite side) of the winding core. The Aufwickelraumbegrenzung runs transversely to the axial direction, in particular in the radial direction. By the

Aufwickelraumbegrenzung a contact of an already wound part of the cable with the main body is prevented or at least reduced, whereby upon rotation of the coil relative to the base body, a friction between the cable and the base body is prevented or at least reduced. Preferably, it is provided that, in the insertion position of the coil, the receptacle extends transversely (ie obliquely) to a connecting line of the two guide windows, in particular of the two sliding areas. This can be unlocked by pulling on both emerging from the device ends of the cable against a Aufwickeldrehrichtung unlockable locking mechanism and released a rotational movement of the coil in the Aufwickeldrehrichtung.

Further preferably, the receptacle is adapted to receive (lead) the (inserted) cable (within the receptacle) S-shaped or mirrored S-shaped. According to a preferred embodiment of the invention it is provided that the receptacle has an S-shaped or mirrored S-shaped profile. As a result, the cable within the receptacle also takes on an S-shape or a mirrored S-shape, whereby cable routing of the cable within the receptacle is made possible. In particular, the course runs through the (kinematic and / or geometric) Rotary axis of the coil. Both curves of the S-shaped or mirrored S-shaped course thus have, in particular, an equal (preferably the largest possible) rounding radius.

It is preferably provided that the receptacle as a (in particular groove-shaped) recess

(In particular in the winding core) is formed with an S-shaped or mirrored S-shaped curve. Further, it is preferably provided that the receptacle is formed as a recess (in particular with an S-shaped or mirrored S-shaped course), and the recesses between the retaining projections at least in an insertion position of the coil to the guide windows (in particular to the openings of the guide window ) to lead. By this configuration, the cable can be easily pressed or striped in the receptacle and the recess. By the S- or mirrored S-shaped profile of the recording, the cable within the receptacle also takes on an S-shape or a mirrored S-shape, whereby a cable-friendly guidance of the cable is made possible within the recording. In particular, the S- or mirrored S-shaped profile of the receptacle transitions tangentially into a winding surface of the winding core, whereby the load on the cable is further reduced. Further preferably, the S- or mirrored S-shaped course runs through the (kinematic)

Rotary axis of the coil. As a result, an equal bending radius is made possible in both deflections of the cable in the recording. Due to the S-shaped course, a cable located in the receptacle extends in the insertion position, in particular transversely to a connecting line of the two guide windows. In addition, the cable is held by friction with the recording in the device by the S or mirrored S-shaped deflection of the cable in the insertion position of the coil. The recesses may in particular be a part or an extension of the S-shaped or mirrored S-shaped course, whereby a particularly simple insertion of the cable is made possible in the device. Preferably, the receptacle (in particular the recess of the receptacle) passes directly into the recesses.

Further preferably, the receptacle projects beyond the winding core in the radial direction. In other words, the receptacle has a larger diameter than the winding core. Thus, the recording for a cable-friendly deflection more space available than her the end face of the winding core (the side facing away from the base body of the winding core) can provide. This is advantageous in particular in the case of an S-shaped or mirrored S-shaped profile of the receptacle, since the curved outer regions of the profile protrude beyond the winding core. If the receptacle is formed as a groove, thus in particular also a groove bottom of the groove projects beyond the groove

Hub beyond. Preferably, the device has an insertion path for inserting the cable into the device, which (at least 80% of its length, in particular at least 90% of its length) has an S-shape or a mirrored S-shape, and to the openings of the guide window leads. Thus, an easily recognizable Einlegepfad the user is given, making the insertion of the cable is much easier. The insertion path thus passes through the receptacle, outside the receptacle through the recesses between the retaining projections and through the openings of the guide window. Thus, along the insertion path, the cable can be inserted into the receptacle by a user

Holding projections, as well as the openings of the guide window are inserted into the device. According to a preferred embodiment of the invention it is provided that the coil has at least one holding means, which is designed to be movable between an open position for insertion of the cable through the recesses and a closed, the recesses at least partially closing position. Thus, the holding means rotates with the coil. In particular, at least in the insertion position of the coil (to the main body) closes the at least one

Holding means thus the recesses. Preferably, the recesses are closed in a radially outer region of the at least one holding means, wherein in particular per recess a holding means is provided. Thus, in a normal operation of the device prevents an already inserted cable unintentionally leaves the device on the recesses (or the insertion path) again. By the at least one holding means can be dispensed with a lid, which covers the coil on a side facing away from the base body, without the cable is lost.

It is preferably provided that the at least one holding means is designed to be elastically movable between the two positions. Characterized in that the holding means so by means of an elastic

Deformation is designed to be movable, a complex and expensive mechanism for the holding means is not required.

In particular, the at least one holding means is an elastically deformable portion of the

Retaining projection. The retaining projection typically has a relatively high ratio of its length (in the radial direction) to its thickness (in the axial direction), whereby the elastic

Deformability is favored. In order to hold the cable at a respective outer end of the recesses in the device, the at least two holding projections in particular each have an elastically deformable portion. The elastically deformable section extends in particular from a radially outer end of the retaining projection to the winding core.

It is preferably provided that an elastic deflection of the at least one holding means in a direction away from the main body direction (in particular in the axial direction of the coil) is limited by at least one stop element. Thus, only with an elastic deformation of the holding means in the direction of the base body, in particular in the axial direction of the coil, the recess for inserting a cable is released. At least in the insertion of the coil, however, a deformation in a direction away from the main body direction of the

Limit stop element such that the recess for a cable is not released. Preferably, the at least one stop element is immovably connected to the retaining projection, or an integral part of the retaining projection. Thus, the at least one holding means ends on the side facing the base body of the adjacent retaining projection. As a result, a mechanically particularly stable stop is given. Preferably, the at least one stop element is immovable with the base body,

in particular the guide window, connected, or an integral part of. As a result, a particularly easy-to-produce stop is given. It is preferably provided that the at least two holding projections in an insertion position of the coil reach as far as the guide windows. This prevents incorrect operation of the user when inserting the cable.

According to a preferred embodiment of the invention it is provided that the at least one holding means at least partially closes the openings of the guide window in an insertion position of the coil. This can be made possible by the guide windows in close proximity to the retaining projections (which is a substantially circular or interrupted circular

Having outer contour) are arranged. The openings of the guide windows can be closed by the at least one retaining means and also by the retaining projection such that an inserted cable is prevented from leaving the guide window. With a substantially circular outer contour of the retaining projection, the guide areas thus remain closed as long as the recesses between the retaining projections are not released by actuating the at least one retaining means. Thus, in the insertion position of the spool (relative to

Body) prevents the cable from leaving the guide windows.

Alternatively or additionally, the openings of the guide window could each also with others

(In particular elastically disclosed) retaining means be reversibly closed, which in each case with the main body, in particular with the respective guide window, (in particular immovable) connected or an integral part of it.

It is preferably provided that the coil has a retaining lug which is designed such that the cable inserted into the device extends on a side of the retaining lug facing the base body. The cable is inserted into the device around the retaining lug when it is inserted into the device. The Einlegepfad for inserting the cable into the device thus extends around an outer contour of the retaining lug. In particular, by an elastic recovery of the cable (or when pulling on both sides of the cable by the user) the cable runs on the side facing the base of the retaining lug. This prevents the cable from leaving the device, in particular the receptacle. The retaining lug is thus preferably arranged in a region of the receptacle (in particular the axis of rotation intersects the retaining lug).

It is preferably provided that the device (within a take-up space of the device provided for the wound-up cable) forms a ramp which rises in the (thus tangential to) take-up rotation direction. Further preferably, the ramp may additionally or alternatively also increase outward in the radial direction. The ramp may be immovably connected to the main body, a lid and / or one of the guide windows or an integral part thereof. If a cable is wound on the winding core, the diameter of the winding of the cable increases with each revolution by twice the cable diameter. If the cable is long enough, that reaches Winding in the radial direction of the guide window. This can cause the coiled cable to jam between the bobbin and the base. Through the ramp, the outermost cable path slides onto the ramp, is raised by the ramp from the take-up in the axial direction (either toward or away from the body), and is pulled toward the hub by the rotation of the spool. As a result, the cable next to the winding forms another winding. Thus, a maximum windable by means of the device length of the cable is increased.

Preferably, it is provided that the winding core on a side facing away from the base body has a wedge whose tip in the direction of Aufwickeid direction (ie tangential to the take-up rotation direction), wherein the ramp thickened in the direction of the body. If a cable is wound, this emerges from the receptacle and is wound around the winding core. The cable is pressed by the ramp in the direction of the body. The portion of the cable pressed by the ramp in the direction of the main body is thus wound around a part of the winding core arranged closer to the main body than that part of the cable which exits from the receptacle on the opposite side. Thus, the axial length of the winding core is better utilized.

It is preferably provided that the device has a locking mechanism for blocking a rotation of the spool in a take-up rotation direction, which in particular can be unlocked by means of a rotation of the spool against the take-up rotation direction. Thus, a locking mechanism is realized which, after a rotation of the spool against the Aufwickeldrehrichtung (at a unwinding of the cable) automatically blocks the rotation of the coil and after a relatively short rotation of the coil (in particular less than 180 °, preferably less than 90 °) against the Aufwickeldrehrichtung (ie by pulling the cable) is unlocked.

Such, by means of a rotation of the spool against the Aufwickeldrehrichtung unlocked

Locking mechanisms typically have in the base body and the spool opposite arranged guideways, in which a locking body is slidably disposed. The

Guideways are in particular formed as groove-shaped depressions (preferably at least partially in the winding-space boundary).

According to a preferred embodiment of the invention, it is provided that the guide track on a first side, which is assigned to the main body or the coil, has:

a circulating winding track, in which a locking body during a rotation of the coil in a direction of Aufwickeid is displaced,

an encircling unwinding track in which the blocking body is displaceable in a rotation of the spool opposite to the take-up rotation direction (in an unwinding direction of rotation),

a connecting track, in which the blocking body is displaceable against the Aufwickeldrehrichtung of the take-up in the unwinding during rotation of the spool, and / or - a Sperrausbuchtung, in which the locking body upon rotation of the spool in the

Aufwickeldrehrichtung is displaceable from the unwinding, and from which the Locking body is displaceable against the Aufwickeldrehrichtung in the take-up when a rotation of the spool.

Typically, the Sperrausbuchtung is provided between the take-up and the unwinding. The guideway on a first side can thus be subdivided into several functional sections according to the function of their respective sections.

According to a further preferred embodiment, it is provided that on a second side, which is assigned to the coil or the main body, and which is arranged opposite to the first side, the guide tracks have:

- A displacement track, in which the locking body is guided and which extends (relative to a rotational axis of the coil) substantially in a radial direction.

The displacement track allows a displacement of the locking body within the guideway of the first side. The unwinding can be provided outside of the take-up. When the translation path is arranged in the spool, as the spool is rotated, the spool also rotates about the axis of the spool. As a result, acts on the locking body, a centrifugal force, which presses him radially outward. Thus, a preferred centrifugal clutch is realized, which is too fast rotation of the coil, for. B. if no cable is inserted, prevents.

Preferably, the take-up is provided outside of the unwinding. In a fast rotation of the spool in the direction of Aufwickeid direction of the locking body is thus no longer pressed by the centrifugal force from the take-up in the Sperrausbuchtung, but pushed away from this, whereby a displacement of the locking body is improved in the Sperrbucht.

The take-up and the unwinding are typically arranged radially offset from one another. In this case, the connecting track can deviate from the radial direction in such a way that, in the case of a direction of rotation of the spool, the blocking body is displaced from the winding track into the unwinding track counter to the direction of winding movement. The Sperrausbuchtung can be connected by means of an inlet track to the unwinding. In this case, the introduction track can deviate from the radial direction in such a way that the blocking body, upon rotation of the spool in the take-up rotation direction, passes from the unwinding track into the barrier bulge. Further, the Sperrausbuchtung be connected by means of a diversion path with the take-up. In this case, the diversion path can deviate from the radial direction in such a way that the blocking body, upon rotation of the spool, counteracts the direction of winding movement of the locking recess in the

Aufwickelbahn is moved. Between the tracks elevations may be provided, which allow the locking body to reach only in the desired direction of rotation in the respective tracks. Furthermore, beginnings of the respective webs may be arranged on such a radius that the blocking body automatically slides into the desired path in the desired direction of rotation as a result of being stuck in its current radial position.

The blocking body can be a ball. As an alternative to the ball, the blocking body may also be a lever which is mounted in particular in the base body in a pivot point and at its the Pivot point facing away from engages in a guideway of the coil. In this case, the (radial) displacement track may be omitted, this variant still requires a lot of space because of the lever. Another alternative may be a U-shaped locking body, which in particular in

Basic body is arranged in a U-shaped, radial displacement track. The legs of the Us surround the shaft of the device. From the U protrudes a cylinder, which slides in the guideway of the coil.

Preferably, however, it is provided that the blocking body is a cylinder. The cylinder can therefore be a hollow cylinder or a solid cylinder. Preferably, it is provided that the locking mechanism in the main body and the spool has oppositely arranged guide tracks, in which the cylinder is slidably disposed, wherein the one end face of the cylinder in the guide track of the base body and the other end face of the cylinder is arranged in the guideway of the coil , One end face of the cylinder thus faces the main body, while the other end side faces the spool. To lock the rotation of the spool in the take-up rotation direction, a positive connection between the guideways of the main body and the spool is thus produced via the cylinder surface of the cylinder. Usually, as mentioned above, a ball is used for such locking mechanisms instead of the cylinder. However, if the coil is accessible to a user and palpable with the hands, the user can apply relatively high torques to the coil, which can lead to an elastic deformation of the device, so that the ball from the

Sperrausbuchtung can slip out and the positive connection is thereby lifted.

Surprisingly, it has been found that even a cylinder sliding in the two guideways is suitable for such a locking mechanism, since the expected

Friction losses of the cylinder in the guideways have surprisingly been found to be irrelevant. Compared to a lever, the cylinder takes up much less space inside the device. Furthermore, the cylinder is characterized by the fact that this in contrast to the ball below

practice-relevant conditions can not slip out of its Sperrausbuchtung, but only slightly tilted. This is the case since the cylinder does not have a spherical surface but a cylindrical surface. It is preferably provided that a diameter of the cylinder is at least 1 time, in particular at least 1.3 times, particularly preferably at least 1.5 times, an axial length of the cylinder. Thereby, the above-mentioned tilting of the cylinder is minimized in an action of an external force in the Aufwickeid direction of rotation of the coil. The locking mechanism is thus more resistant to external influences. In addition, a lubricity of the cylinder is improved.

It is preferably provided that the device has a blocking mechanism which by means of pushing or pushing by a user into a rotation of the coil at least in the

Aufwickeldrehrichtung blocking position and the rotation of the coil permitting position is switchable. In particular, in the blocking position, the rotation of the spool is blocked against the Aufwickeldrehrichtung. The blocking mechanism remains independently in the respective position (until it is switched by the user). As a result, the rotation of the spool can be locked by the user independently of the locking mechanism, so that it does not accidentally unlocked. In addition, the rotation of the spool can be locked by means of the blocking mechanism in intermediate positions of the locking mechanism. Furthermore, it can be provided that the blocking mechanism against the Aufwickeldrehrichtung not block the rotation of the coil, so that the cable can be unrolled by the user.

According to a preferred embodiment of the invention it is provided that the coil is arranged transversely to the axial direction of the coil (ie extending transversely to the axial direction)

Mechanism for limiting rotation of the spool (especially against the

Aufwickeldrehrichtung), wherein the mechanism has a first portion which for blocking the rotation of the coil, in particular from the retaining projection, protrudes and the

Mechanism has a second portion which extends into the receptacle, so that the cable arranged in the recording in a tensile load, the mechanism is actuated such that the first portion in the direction of the coil, in particular in the direction of the retaining projection, retracts and the rotation (in particular against the take-up rotation direction) of the spool releases. As a result, the coil z. B. locked regardless of a locking mechanism. When the mechanism locks the rotation against the take-up rotation direction, the lock mechanism can not be unlocked counter to the take-up rotation direction. For this purpose, it is provided in particular that one of the

Mechanism permitted rotation angle opposite to the take - up rotation direction smaller than one to

Unlocking the locking mechanism necessary rotation angle is. In addition, a torque which can be applied by the user to the axle is limited in the opposite direction to the take-up rotation direction (which keeps the spring tensioning). Preferably, the mechanism is a lever, or the mechanism comprises one which is pivotally mounted in particular between its first and second portion. Further preferably, the mechanism is a slider or includes such, which is slidably mounted in particular between its first and second portion. The mechanism may comprise a spring element, which biases the mechanism (ie, the lever or the slide) such that its first portion protrudes from the coil, in particular from the retaining projection, if the tensile load fails. In particular, by a deflection of the cable (ie by a change in direction of the longitudinal extent of the cable) by means of the recording, it is possible that the mechanism is actuated by a tensile load of the cable. In particular, the mechanism forms at least a part of the retaining projection.

It is preferably provided that the device has a cover on a side of the coil facing away from the main body. Thus, at least one part of the coil facing away from the main body can be covered by means of the cover. The lid is in particular (by a user) apparently, z. B. folding, swiveling or removable. With an open lid, the cable is inserted into the device, while a closed lid prevents removal of the cable.

Preferably, the lid closes the openings of the guide window, further preferably (also) the recesses between the retaining projections and in particular (also) the recording.

Preferably, the device comprises a barrier which by means of opening the lid in a position blocking the rotation of the spool and by closing the lid in a rotation of the coil permissable position is switchable. This provides a simple fuse to prevent the coil from rotating without an inserted cable (for example, when inserting the cable).

Preferably, it is provided that the lid is pivotally connected to the base body, wherein a pivot axis for pivoting the lid is preferably arranged transversely, in particular at right angles, to the axial direction of the coil. Further preferably, the lid has a in the axial direction in the direction of the base body and / or radial direction in the direction of the axis of rotation extending stopper body which engages upon opening of the lid in a blocking recess of the retaining projections or Aufwickelraumbegrenzung. Thus, a reliable positive connection between the lid and the associated base body on the one hand and the coil on the other hand given. Depending on whether the Sperraussparung in the retaining projections or the

Aufwickelraumbegrenzung is arranged, it may be useful to arrange the pivot axis on the retaining projections or the Aufwickelraumbegrenzung associated side of the device. Preferably, the lid is pivotally connected to the body in a confinement of one of the guide windows, whereby a space-saving arrangement is realized. The stopper body can also be connected to transmit power as a separate component with the lid.

If only a single Sperrauussparung is present, in which the stopper body in a

Insertion of the coil can engage, so opening the lid is prevented in other positions of the coil. The holding projections or the Aufwickelraumbegrenzung have in particular a plurality, preferably evenly distributed, barrier recesses. Thus, the lid can be opened in several positions of the coil. Preferably, webs between the blocking recesses have a tapering towards the stopper body shape. Also preferably, the stopper body has a tapered towards the barrier recesses shape. Thus, an intervention of the

Stop body facilitates in the Sperraussparungen.

Preferably, the lock on a stop body, which (spring-loaded) is connected to the base body and / or the lid, that the stopper body in an open lid in a rotation of the spool blocking position and a closed lid in a rotation of the Coil permitting position is located. As a result, a simple fuse is provided to prevent rotation of the coil with an open lid. The lid and / or the body can do so in the closed position of the lid to move the stopper body in the rotation of the coil permitting position. For example, the stopper body may be spring-loaded connected to the main body. In the closed position of the lid, the stopper body is then pressed from the lid to the base body and thus away from the coil. In an open lid, however, the spring-loaded stopper body is pressed to the coil and blocks it.

The blocking mechanism, the mechanism for limiting a rotation of the spool and / or the lock are preferably designed to block the rotation of the coil positively and / or non-positively. According to a preferred embodiment of the invention it is provided that the lid has a centrally disposed opening or a (in particular centrally arranged) viewing window. Thus it can be recognized if an inserted cable has slipped at least partially out of the receptacle. The alternative with the centrally located opening also has the advantage that a cable which has slid at least partially out of the receptacle does not grind on the lid. The opening is preferably circular and / or coaxial with an axis of rotation of the coil. The viewing window is formed in particular by a transparent material. Furthermore, the lid itself may be transparent.

Preferably, the receptacle protrudes at least partially into the opening. By this design height is saved, since a space requirement in the axial direction, which claimed the cover for himself, is not added to a space requirement of the recording. In particular, a diameter of the opening is larger than a diameter of the winding core, in particular the receptacle. Thus, the entire recording takes place within the opening. With a further increased diameter of the opening, a deflection of the cable at an exit from the receptacle in the direction of the main body can still be done within the opening, so that the cable does not come into contact with the lid. Furthermore, it can be provided, in particular, that an outer surface of the coil, in particular of the receptacle, terminates flush with an outer surface of the lid. Thus, a particularly compact device is created.

Preferably, the device also includes a garment-fixing means (e.g., a clip) for securing the device to a user's clothing, making the device particularly suitable for use with headphone cables. Furthermore, the device preferably has at least one cable fixing means for fixing one end of the cable to the device. The cable fixing agent may, for. B. may be formed as a tapered slot for clamping the cable. Furthermore, the fixing means may have a through-opening and a channel (in particular with a width smaller than a diameter of the through-opening), wherein the channel connects the through-opening with the surroundings. Thus, the cable can be inserted laterally through the channel in the through hole. Pulls the coil on the cable, it remains z. B. hang a plug of the cable to the border of the through hole and the cable is fixed. The cable fixing means can also be formed as a notch, in which the cable is inserted laterally, wherein the notch is oriented such that when the coil pulls on the cable, the cable is pulled in the direction of the notch base and z. B. a plug of the cable gets stuck on the notch. The garment fixing means and / or the cable fixing means may be disposed on the housing or the lid. In addition, a system comprising a device according to the invention and a cable is provided. The cable is in particular inserted in the receptacle of the device. By the device, the cable can be rolled up gently by the spring cable. The device may be designed so that the cable is integrated into the device, ie not by a user

(non-destructive) is interchangeable. This can be z. B. by means of a glued to the base lid. Furthermore, the device can also be designed such that the cable is exchangeable by a user. It is also provided, a device for winding a cable with

a coil having a winding core and a receptacle for transmitting a rotational movement of the coil to the cable, and

a base body, to which the coil is rotatably mounted.

Also, this device is with the above-mentioned, preferred embodiments

combined. Preferably, this device also comprises a spring (in particular arranged in the winding core) which is connected to the coil and the base body in a manner transmitting spring force. Further preferably, it is provided that the spring is arranged in an axial direction of the coil between the receptacle and the base body. Thus, here are the benefits mentioned in the introduction.

Figures 1 to 1 1 show a device 10 (or individual parts thereof) for reversibly inserting and winding a cable 1 1 according to a preferred embodiment of the invention. Further preferred embodiments of the invention can be seen in FIGS. 12 to 20. The device 10 comprises a coil 12, which has a winding core 14 and a receptacle 16. The receptacle 16 is used to transmit a rotary movement of the coil 12 on the cable 1 1 (see Figure 10).

The device 10 comprises a main body 20, to which the spool 12 is rotatably mounted.

In addition, the device comprises a spring 22, which is arranged in the winding core 14, and is connected to the coil 12 and the main body 20 so as to transmit spring force. The spring 22 is arranged in an axial direction A of the coil 12 between the receptacle 16 and the base body 20. This is best seen in Figure 9, which shows a section B-B of Figure 8.

The spring 22 may be connected via the shaft 21 with the main body 20 to transmit spring force. With the coil 12, the spring 22 may be connected to transmit spring force by the spring in a Federhalterhalterungsabschnitt 23 of the winding core 14 hooks (see Figures 9, 1 1, 12). The spring 22 may be a coil spring capable of bearing torque. The spring 22 is oriented so that it is tensioned against the Aufwickeldrehrichtung 44 of the coil 12, ie in a Abwickeldrehrichtung the coil 12.

The coil 12 may be connected via the shaft 21 to the base body 20 and rotatably mounted on the shaft 21. The coil 12 could, however, also be mounted on a (hollow) axis formed by the main body 20, that is to say a projection of the main body 20 through which the shaft 21 protrudes. The coil 12 can thereby by means of a positive connection 24 rotatably on

Main body 20 are held. In the example shown, the positive connection 24 between the spring 22 and the base body 20 is arranged. For this purpose, the shaft 21 may have a particular peripheral thickening 25, which holds the coil 12 positively on the base body 20 (see Figures 2, 5 and 9).

The device 10 may have two on opposite (radial) sides arranged guide window 26 for feeding the cable 1 1 to the winding core 14 during winding of the cable 1 1. The guide window 26 may have openings 33 for inserting the cable 1 1. As shown (see in particular FIG. 11), the guide windows 26 can be integral components of the main body 20. As can be seen, the main body 20 may be plate-shaped and / or trough-shaped apart from the guide windows 26. The guide windows 26 have boundaries 27 (see FIG. 7), which prevent retraction of a thickened end (eg a plug) of the cable 1 1. The

Limitations 27 can also be omitted, whereby the guide window 26 each extend over almost 180 ⁰ . Thus, the openings 33 of the guide window 26 are largely closed by retaining projections 28.

The coil 12 may comprise at least two retaining projections 28 for holding the cable 1 1 on the winding core 14. In the example shown, exactly two retaining projections 28 can be seen, but the two retaining projections 28 could also be divided into a plurality of retaining projections 28.

Retaining projections 28 project from the winding core 14 transversely to the axial direction A of the spool 12 on a side of the winding core 14 facing away from the main body 20. In addition, two recesses 32 for inserting the cable 1 1 may be provided between the retaining projections 28.

The receptacle 16 may be designed to make the cable S-shaped or mirrored S-shaped

take. For this purpose, the receptacle 16 can have an S-shaped or mirrored S-shaped profile, in particular, as shown, be formed as a recess with an S-shaped (or alternatively also with a mirrored S-shaped) course (see in particular those framed in FIG Picture 16). Further, the recesses 32 between the retaining protrusions 28 in an insertion position of the spool 12 (the position shown in the figures) to the openings 33 of the

Guide window 26 lead. In particular, an insertion path 30 for inserting the cable 1 1 into the device 10 may have the S-shaped (or alternatively also the mirrored S-shaped) profile (see FIG. 8). As a result, the insertion of the cable 1 1 is greatly facilitated by the user.

The spool 12 may comprise at least one holding means 34 which is movable between an open position 38 for inserting the cable 1 1 through the recesses 32 and a closed, the recesses 32 at least partially closing position 39 (see in particular Figures 7 and 8). In the example shown, the device has two holding means 34, which each have a

At least partially close recess 32. The holding means 34 shown are designed to be elastically movable between the two positions 38, 39, in that the at least one holding means 34 is an elastically deformable section of the holding projection 28. The deformable portion extends from a radially outer end of the retaining projection 28 to the winding core.

An elastic deflection of the at least one holding means 34 in a direction away from the main body 20 direction, in particular in the axial direction A, at least in the shown

Insertion of the coil 12 is limited by means of stop elements 36.

The two holding means 34 close in an insertion position of the coil 12, the openings 33 of the guide window 26 at least partially. In part, the openings 33 are also of the

adjacent retaining projection 28 closed. Also, between the holding means 34 and the adjacent holding projections 28, the cutouts 32 can also extend to the openings 33 with a substantially narrower width in plan view. However, the width of the recesses 32 in the region of the holding means 34 is less than a diameter of typically with the

Device 10 wound cables 1 1. Also a gap between the guide windows 26 and the Holding projections 28 are dimensioned so that it is smaller than the diameter of the typically wound with the device 10 cable 1 1.

The coil 12 may have a retaining lug 40. The inserted into the device 10 cable 1 1 extends on a side facing the base 20 side of the retaining lug 40 (see Figure 10).

The device may include a locking mechanism 42 for blocking rotation of the spool 12 in the take-up rotation direction 44 (see FIGS. 3 and 4), which is unlockable by rotation of the spool 12 against the take-up rotation direction 44. The locking mechanism 42 may further in the base body 20 and the spool 12 oppositely disposed guide tracks 46, 47 (grooves), in which a locking body 48, in this case a cylinder 48, is slidably disposed. The one end face 49 of the cylinder 48 is arranged in the guide track 46 of the base body 12 and the other end face 49 of the cylinder 48 in the guide track 47 of the coil 12. On a first side, which is assigned to the base body 20 in the example, has the guideway

46, a circumferential winding track 52 (the innermost track in Figure 3), in which the locking body 48 is displaceable upon rotation of the spool 12 in a Aufwickeldrehrichtung 44. In addition, this guideway 46 has a circumferential Abwickelbahn 53 (the outermost track in Figure 3), in which the locking body 48 is displaceable against the Aufwickeldrehrichtung 44 upon rotation of the spool 12. Furthermore, the guide track 46 has a connecting track 54, in which the locking body 48 is displaceable against the Aufwickeldrehrichtung 44 of the take-up track 52 in the Abwickelbahn 53 upon rotation of the coil 12. The guideway 46 also has a Sperrausbuchtung 55, in which the locking body 48 is displaceable upon rotation of the spool 12 in the Aufwickeldrehrichtung 44 from the Abwickelbahn 53, and from which the locking body 48 during rotation of the spool 12 against the Aufwickeldrehrichtung 44th is slidable in the take-up web 52. The

Sperususbuchtung 55 is provided between the take-up web 52 and the Abwickelbahn 53.

On a second side of the locking mechanism 42, which is associated with the coil 12, and which is arranged opposite to the first side, a guide track 47 is arranged (see Figure 4). The guideway 47 may be provided in a particular circulating Aufwickelraumbegrenzung 56 of the coil 12. The Aufwickelraumbegrenzung 56 is disposed on a base body 20 facing side of the winding core 14 and reduces or prevents contact of a wound cable 1 1 with the base body 20, whereby friction during winding is reduced. The guideway

47 is a displacement track 47, which (relative to a rotational axis D of the coil 12) in

Substantially in a radial direction R extends. The radial direction R denotes an arbitrary direction as long as it points perpendicularly from the rotation axis D (see FIG. 9) or toward the rotation axis D. The sliding track 47 allows a displacement of the locking body 48 within the guide track 46 of the first side. The sum of the depths of the guideways 46, 47 may be approximately equal to an axial length of the cylinder 48. By a game between the guideways 46, 47 thus results in a game of the cylinder 48 to the guideways 46, 47. Furthermore, the sum of the depths can also be less than that be axial length of the cylinder 48, so that the cylinder 48 is substantially free of play in the guideways 46, 47 is displaceable or even slightly pressed by the guideways 46, 47. The unwinding web 53 can be provided outside the take-up web 52, as shown in the example. Characterized in that the locking body 48 rotates with a rotation of the spool 12 with this, acts on the locking body 48, a centrifugal force, which presses him radially outward. At extremely large

Angular velocities, as z. B. occur when a relaxation of the spring 22 without a pickled cable 1 1, the locking body by the centrifugal force of the take-up web 52 in the

Sperrausbuchtung 55 pressed. As a result, a centrifugal clutch is realized which a

Uncontrolled relaxation of the spring 22 prevented.

Alternatively, the take-up web 52 may also be provided outside the unwinding web 53. With a fast rotation of the spool 12 in the take-up rotation direction 44, the blocking body 48 can thus no longer be pressed out of the take-up web 52 into the barrier groove 55 by the centrifugal force. Rather, the locking body 48 is pushed away from the Sperrausbuchtung 55. By this arrangement, a deliberate locking of the lock mechanism 42 is improved. This is triggered by the locking body is in the (now inner) Abwickelbahn 53 and the coil 12 in the

Winding direction of rotation 44 rotates. The centrifugal force now a leakage of the locking body 48 from the Abwickelbahn 53 and an entry of the locking body 48 in the Sperrausbuchtung 55 (which is now arranged outside the Abwickelbahn 53) is supported.

As already known, the take-up web 52 and the take-off web 53 are typically arranged offset radially relative to one another. In this case, the connecting track 54 can deviate from the radial direction R such that the blocking body 48 counteracts the direction of rotation of the spool

Aufwickeldrehrichtung 44 is shifted from the take-up web 52 in the unwinding 53. The Sperrausbuchtung 55 can be connected by means of an inlet track 57 with the Abwickelbahn 53. In the example shown, the inlet track 57 is designed to be extremely short, essentially the inlet track 57 has only one outer wall for guiding the blocking body 48. In this case, the introduction path 57 can deviate from the radial direction R in such a way that, when the coil 12 rotates in the take-up rotation direction 44, the blocking body 48 passes from the unwinding track 53 into the barrier groove 55. Furthermore, the barrier bulge 55 may be connected to the winding track 52 by means of a diversion path 58. In this case, the diversion path 58 can deviate from the radial direction R in such a way that the locking body 48 is displaced from the locking recess 55 into the take-up track 52 when the spool is rotated counter to the take-up rotation direction 44. Between the tracks 52, 53, 54, 57, 58 may be provided (eg ramp-shaped or wedge-shaped) elevations (not shown) which allow the locking body 48 to move into the respective track 52, 53 only in the desired direction of rotation , 54, 57, 58 arrive. Furthermore, starts of the respective track 52, 53, 54, 57, 58 may be arranged on such a radius that the locking body 48 automatically slides in the desired direction of rotation in the desired direction of rotation as a result of being stuck in its current radial position (see FIG. 3). Characterized in that the positive connection 24 which rotatably holds the coil 12 rotatably on the base body 20 is disposed between the spring 22 and the base body 20, a possible play-free and rigid construction of the locking mechanism 42 is given. The shaft 21 is connected to the

Base body 12 connected such that a torque from the shaft 21 to the base body 12 is transferable. In the example shown, the shaft 21 is immovably connected to the base body 20. This is done by the shaft 21 shown in Figure 5 has a slotted form caliper 60. A form saddle slot 61 which divides the form caliper 60 into two halves is disposed in a common plane with a spring retainer slot 62 in which the spring 22 is hooked. Of the

Formsattelschlitz 61 may reach 25 to the circumferential thickening and thus divide a bearing surface 63 for (sliding) storage of the coil 12.

Alternatively, the shaft 21 could, for example, also integrally connected to the base body 12, so be an integral part of the body 12. Furthermore, the device 10 may include a blocking mechanism 64 which, by pushing or pushing by a user, into a rotation of the spool 12 at least in the

Aufwickeldrehrichtung 44 blocking position 78 and the rotation of the coil 12 permitting position 79 is switchable. For this purpose, the blocking mechanism 64 shown in FIGS. 3, 4, 6 and 7 has a slide 65, which is shown on an underside of the device 10 which can be seen in FIG. The slider 65 is immovable or integrally connected to a blocking nose 66. By means of the blocking nose 66 is a positive connection with a in the

Aufwickelraumbegrenzung 56 arranged teeth 67 produced.

The device 10 may have ramps 68 immovably connected or integrally formed with the base body 20 (see FIG. 7). Furthermore, the coil may have a wedge 69 (see FIG. 12). The ramps 68 and the wedge 69 lead the cable 1 1 during winding.

FIG. 12 shows a coil 12 (or a part of the coil 12) that is alternative to the preceding figures. Accordingly, the coil 12 itself has two stop elements 37. The holding means 34 terminate on the base body 12 facing side of the adjacent retaining projection 28 and the stop element 37. The holding means 34 thus overlap the stop elements 37. This gives a mechanically particularly stable stop, which also with the Stop elements 36 can be combined. In Figs. 13 and 14, a mechanism 70 integrated with the spool 12 for limiting rotation of the spool 12 is provided. The mechanism shown limits a rotation of the spool 12 against the take-up rotation direction 44. One possible, permitted rotation of the spool 12 opposite to the take-up rotation direction 44 is smaller than a rotation at least necessary for unlocking the lock mechanism 42. The at least necessary for unlocking rotation is that rotation which is required to move the locking body 48 so far in the take-up web 52 that this remains in a subsequent rotation of the spool 12 in the take-up rotation direction 44 in the take-up web 52. The mechanism 70 is arranged transversely to the axial direction A of the spool 12. It can adjoin one of the holding projections 28 and extend on its side facing the main body 20. The mechanism 70 may be formed as (or include) a lever 70a and include a first portion 72 that protrudes from the retention projection 28 to block rotation of the spool 12. Furthermore, the mechanism 70 may include a second portion 74 which extends into the receptacle 16. The lever 70a may be pivotally mounted on a shaft (not shown) of a screw 76. Instead of the shaft of the screw 76, any other storage for the lever 70 a may be provided. The lever 70a can be supported by means of an end stop 77. An unillustrated spring element which, for example, an integral

Component of the lever 70a, biases the lever 70a such that its first portion 72 protrudes from the retaining projection 28. It may also be provided per holding projection 28, a separate mechanism 70. The mechanism 70 may, according to FIGS. 15 and 16, also be in the form of or comprise a slider 70b instead of a lever 70a. The slider 70b is, for. B. along its longitudinal direction, in the coil 12 slidably formed - see Figures 15 and 16. Otherwise, its function corresponds to that of the lever 70 a. The slider 70b extends between the receptacle 16 and the spring 22 and in particular forms at least part of the receptacle 16th

According to FIGS. 17 and 18, the device 10 can have a cover 80 on a side of the coil 12 facing away from the main body 20. In addition, the device 10 may have a barrier 82, which by means of opening the lid 80 in a rotation of the spool 12 blocking position 78 and by closing the lid 80 in a rotation of the coil 12 permitting position 79 is switched. The lock 82 may be formed as (or comprise) a stopper body 82 and connected to the lid 80, e.g. B. fixed (ie, for example, integral), be connected. The stopper body 82 can engage in a blocking recess 81 of the retaining projection 28 (or in one of a plurality of blocking recesses 81 of the retaining projections 28). As can be seen in FIGS. 19 and 20, the stopper body 82 can also engage in a blocking recess 81 (in particular of a plurality of blocking recesses 81) in the winding-space boundary 56. By apparent in Figures 19 and 20, (oppositely oriented) tapered shape of the stopper body 82 and / or webs 83 between the Sperraussparungen 81 an engagement of the stopper body 82 is facilitated in the Sperraussparungen 81.

It can also be seen in FIGS. 19 and 20 that the cover 80 can have a centrally arranged opening 88. The coil 12, in particular the receptacle 16, can project into the opening 88. Furthermore, an outer surface 89 a of the coil 12, in particular of the receptacle 16, can be flush with an outer surface 89 b of the lid 80.

The embodiment according to FIGS. 19 and 20 has no holding means 34 and stop elements 36, 37, since the lid 80 ensures the fixation of an inserted cable 11 in the device 10. Likewise, it could also be dispensed with in an embodiment according to FIGS. 17 and 18. However, it would also be possible in the embodiment according to FIGS. 19 and 20 to provide the holding means 34 and in particular also the stop elements 36 and / or 37. In addition, the barriers 82 (see FIGS. 17 to 20) can also be combined with the mechanisms 70 (see FIGS. 13 to 16).

In Figure 1 1 is best seen how the device 10 can be assembled. First, the blocking mechanism 64 is connected to the main body 20, z. B. by the slider 65 is clipped together with a support of the blocking lug 66. Subsequently, the blocking body 48 can be inserted into the guide track 46 (see FIG. 3).

Subsequently, the Aufwickelraumbegrenzung 56 of the coil 12 is placed on the base body 20 and the shaft 21 is inserted. This is done by expanding the spring retainer slot 62, thereby narrowing the saddle slot 61. Thus, the form saddle 60 can be inserted into the base body 20, and the

Form saddle 60 are spread by a grub screw 84 (see Figure 6). As a result, the device 10 according to FIG. 2 is obtained. Alternatively, the coil 12 could also be held in a form-fitting manner on the base body 20 by means of a clip connection (not shown) provided on the shaft 21.

Subsequently, the spring 22 is suspended in the spring support portion 23 (see FIG. 12) and inserted into the winding core 14. Then, the spring 22 hooked into the spring retaining slot 62 of the shaft 21 and the upper part of the coil 12 (the winding core 14 together with the retaining projections 28) are placed on the Aufwickelraumbegrenzung 56. In this state, the mechanism 70 can still be used in the coil 12. Subsequently, the upper part of the coil 12 needs with the

Aufwickelraumbegrenzung 56 are screwed only with the two screws 76. For this purpose, not shown nuts in nut holders 86 (see Figure 4) may be provided. Instead of the

Screws 76 may of course also retaining clips (not shown) may be provided by means of which the coil 12 can be connected in itself (in the example, the upper part of the coil 12 with the Aufwickelraumbegrenzung 56).

Before the delivery of the device 10, the spring 22 can still be tensioned counter to the take-up rotation direction 44. A rotation of the spool 12 in the take-up rotation direction 44 is determined by the

Locking mechanism 42 prevents. In addition, a rotation of the coil 12 still through the

Mechanism 70, the lock 82 of the lid 80 and / or the blocking mechanism 64 are prevented.

From the cylinder 48 relatively large, acting on the spool 12 in the winding rotation direction 44 torques are absorbed, whereby the cylindrical surface 50 of the cylinder 48, even with an elastic extension of a game between the main body 20 and the retaining restriction 56 not from the guideways (guide grooves) 46th , 47 can slide, but only obliquely. This stability is further increased, the larger the ratio of the diameter of the cylinder 48 to its axial length. The operation of the device 10 according to a preferred embodiment of the invention will be discussed below: The cable 1 1 is inserted along the insertion path 30 in the device 10 (see Figure 8). For this purpose, the approximate center of the cable 1 1 is first determined. Subsequently, the cable 1 1 is pressed under the retaining lug 40 or suspended in this. Thereafter, the cable 1 1 is placed on both sides of the retaining lug 40 in the receptacle 16 and by the adjacent recesses 32, or striped. To put the cable 1 1 through the openings 33 in the guide window 26, the elastic holding means 34 can be pressed to the base body 20 (see Figure 7), whereby the holding means 34 are transferred from the closed position 39 to the open position 38 and the outer part of the recesses 32 and the openings 33 of the cable guide portions 26 release. Then the cable 1 1 can be placed in the guide window 26. Alternatively, one end of the cable 1 1 can be pulled in the direction of the main body 20, whereupon the cable 1 1 presses the respective holding means 34 to the main body 20. Through the preceding steps, the cable 1 1 in the device 10 is inserted (see Figure 10). Thus, the cable runs on the side facing the base body 20 of the retaining projections 28 and the retaining lug 40, as well as within the receptacle 16 and the guide window 26. In one embodiment of the device according to FIGS 17 to 20 can still be closed, the lid 80, which z. B. by means of at least one retaining clip 87 in its closed position (see Figures 19 to 20) can be held. By closing the

Cover 80, the stopper body 82 is moved out of the Sperraussparung 81, whereby the lock 82 no longer blocks rotation of the spool 12.

Overall, a system 100 (see FIG. 10) is now realized which comprises the device 10 and the cable 11.

In the position shown in FIG. 10, ie the insertion position of the coil 12 relative to the main body 20, the cable is prevented by the holding means 34, the retaining lug 40 and the S-shaped profile of the receptacle 16 from passing through the insertion path 20 to leave. In addition or alternatively, the cable can also be prevented by the cover 80 (see FIG. 17 or 19).

The holding means 34 prevent the cable 1 1 z. B. then leaving the device 10 when the ends of the cable 1 1 are pulled in a direction away from the base body 20, axial direction A. This is done by limiting or preventing elastic deformation of the holding means 34 in this axial direction A by means of the stop elements 36 or 37 (see FIG. 12). In a very strong train on the cable 1 1, however, the holding means 34 can slide by an increasing elastic deformation of the holding means 34 and release the cable 1 1 to prevent damage to the cable 1 1. The S-shaped receptacle 16 prevents the cable 1 1 from leaving the device 10 by the cable 1 1 is frictionally held in the receptacle 16 by the double, opposite bending of the cable 1 1, without being trapped in the receptacle 16. The cable 10 extends between the two curves of the S-shaped receptacle substantially straight, whereby the cable 1 1 is held by the retaining lug 40 in the device 10 (see Figure 10). The cables 11 for which the device 10 is provided are typically substantially thicker than the cable 11 shown in FIG. 10 - typically twice as thick. Thus, the effect of the retaining lug 40 is improved because the inserted cable 1 1 in the form of the insertion path 30 (see Figure 8) must be bent around the retaining lug 40 in order to leave the device 10 again. A length of the retaining lug 40 perpendicular to the insertion path 30 may in particular correspond to a width of the receptacle 16, whereby the effect of the retaining lug 40 is further improved. The retaining lug 40 may, for example, extend as far as the position 41 (marked by the arrowhead in FIGS. 8 and 10) or even beyond. As a result, it may be necessary that as compared to the illustration in Figure 8 and 10, the recess (groove) of the receptacle 16 in the area of the retaining lug 40 expands (ie widened) is that the cable 1 1 can be guided around the retaining lug 40.

For winding the cable 1 1, of which only a very small, central portion is shown in FIG. 10, the blocking mechanism 64 (if present) is first unlocked. For this purpose, the slider 65 of the blocking mechanism 64 (see Figure 6) is pushed outwards. As a result, the blocking lug 66 (see FIG. 3) is pushed out of the toothing 67 (see FIG. 4).

Then 1 1 is pulled on the cable. When the device 10 has the mechanism 70 shown in FIGS. 13 and 14 in the form of the lever 70a, pulling pulls the lever 70a (clockwise) against its spring, not shown, whereby its first portion 72 disappears in the retaining projection 28 and the Rotation of the spool 12 against the Aufwickeldrehrichtung 44 releases. When the mechanism 70 includes the slider 70b (FIGS. 15 and 16), pulling pulls the slider 70b inwardly against its unillustrated spring causing its first portion 72 to disappear in the retaining projection 28 and rotate the spool 12 counter to the winding rotational direction 44 releases.

By pulling on both ends of the cable 1 1, the locking body 48 is pushed by the displacement track 47 through the diversion path 58 in the take-up web 52. If the cable 1 1 then released or its ends moved in the direction of the device 10, so the spring 22 independently rolls the cable 1 1, by relaxing and the spool 12 in the take-up rotation 44 rotates.

The cable 1 1 is gently deflected during winding of the S-shaped receptacle 16 on the largest possible bending radius, which corresponds approximately to half the diameter of the winding core, whereby cable break is prevented. It is particularly advantageous if the S-shaped, or mirrored S-shaped receptacle 16 in the insertion position such an angle to the

Guide windows 26 has that of the receptacle 16 located in the part of the cable 1 1 at

Unlock the locking mechanism 42 not against its S-shaped or mirrored S-shaped Bend is bent straight. This prevents a repeated bend on the radius of the recording.

The winding takes place until the cable 1 1 is either completely rolled up, or the slider 65 of the blocking mechanism 64 is pushed in the direction of the center of the device 10 and its blocking lug 65 engages in the toothing 67. The blocking mechanism 64 has notches in its two end positions so that it dwells safely in the respective position.

In addition, the winding of the cable 1 1 can be terminated by a short distance is pulled at the ends of the cable 1 1 against the spring force of the spring 22, whereby the coil 12 is rotated counter to the take-up rotation 44. As a result, the locking body 48 is moved in the take-up web 52 against the Aufwickeid direction of rotation 44, passes through a Abwickelnocke 90 to a radius closer to the Abwickelbahn 53 (a larger radius) and thereby in the connecting path 54. During the locking body 48 in the Abwickelbahn 53 opposite the take-up rotation direction 44 is shifted, it is moved by a locking cam 92 to a radius closer to the take-up web 52 (a smaller radius). If the user now lets go of the cable 1 1, then the locking body 48 is moved in the Aufwickeldrehrichtung 48 and passes through the inlet path 57 into the Sperrausbuchtung 55. Thus, a desired length of the cable 1 1 outside of the device 10 is reached. In order to pull out the cable 1 1 to any length or completely, needs to be pulled on the cable 1 1 only, whereby the locking body 48 of a Entsperrnocke 94 in the take-up web 52 (a smaller

Radius) is moved, whereupon the locking mechanism 42 also passes through the phases described in the introduction in this paragraph.

Even if the rotation of the spool 12 is blocked by the lock mechanism 42, the user can additionally lock the rotation by means of the lock mechanism 64. This prevents inadvertent unlocking of the lock mechanism 42.

As soon as a tensile force is applied to the cable 1 1 by the spring 22 during winding or unwinding, the base body 20 is supported on the cable 1 1 via the guide window 26. To an allocation of the cable 1 1 on certain axial areas of the winding core 14 even with the largest possible

To allow guide windows 26, at least one of the guide window 26 has an inclined sliding portion 96 (see Figure 7). The inclined sliding portion 96 is located in the guide window 26 furthest in the take-up rotation 44. The inclined sliding portion 96 is inclined to the base body, whereby the cable 11 slides in the direction of the base body 20 through the support of the base body 20 via the inclined sliding portion 96. The second guide window 26 may have another, inclined away from the base body 20, inclined sliding portion (not shown), whereby at this the cable 1 1 slides away from the base body 20. Since the recording 16 but at the

Body 20 is remote from the side of the winding core 14, it is sufficient if the second, oppositely arranged guide window 26 forms an axially extending sliding portion 98 (see Figure 7). When winding the cable 1 1 can additionally or alternatively to the inclined sliding portion of the wedge 69, the cable 1 1 press in the direction of the body 20, whereupon by the axial offset of the two sides of the cable 1 1 on the device 10 acts a torque which the device 10 obliquely relative to the cable 1 1 and a winding of the cable 1 1 favors in separate, axially staggered windings.

If the cable 1 1 wound on the winding core 14, so the diameter of the winding (not shown) of the cable 1 1 increases. If the cable 1 1 is long enough, the winding in the radial direction R reaches the guide window 26. By the ramps 68 (one of which can be seen in Figure 7) slides the outermost cable path of the winding on the ramp 68, is through the ramp 68th of the

Winding in the axial direction A lifted away from the base body 20 and pulled by the rotational movement of the spool 12 to the winding core 14. As a result, the cable 1 1 forms next to the winding another winding. Thus, by means of the device 10 maximum windable length of the cable 1 1 is increased by the ramp 68. The device 10 may also have at least one oppositely oriented ramp (not shown), which counteracts the winding of a farthest from the base body 20 end of the winding core 14 in the axial direction A of the main body 20.

If the device 10 has a cover 80 (FIGS. 17 to 20) and the cover 80 forms an opening 88, then a cable 1 1 slipped slightly out of the receptacle 16 does not drag on the cover 88.

To remove the cable 1 1, the cable 1 1 is rolled to its maximum length. Subsequently, the holding means 34 are pressed to the base body 20 and the cable 1 1 removed. If provided, the spring-loaded lever 70a pivots counterclockwise by eliminating the voltage in the cable 1 1 or the spring-loaded slide 70b pushed out of the retaining projection 28, whereby its first portion 72 blocks re-rotation of the coil 12 against the Aufwickeldrehrichtung 44. Additionally or alternatively, the lid 80 may be opened, whereby the lock 82 automatically blocks the rotation of the spool 12.

In summary, it can be stated that a device 10 for rolling up a cable 1 1 has been created by the device 10, which device is easy to operate and operate effectively. LIST OF REFERENCE NUMBERS
