Description

The invention relates to a device, in particular animal guide device, with a housing and with a rotatably mounted relative to the housing winding drum on which a leash or a tape wound and, in particular against the restoring force of a spring device, again unwound, and with a stopping device, with in that a rotation of the winding drum can be blocked at least for the unwinding direction by means of a blocking element which can be transferred from a release position into a blocking position.

Often, animals, especially dogs, are guided by means of devices in which a leash or band from a departing animal can be unwound from a winding drum against the return force of a spring device. As soon as the animal approaches again, the leash or ribbon is automatically rewound. Devices of this type are often designed as dog leashes, which usually have a leash or a band of a length in the range of 3 meters to 10 meters.

Often, however, it is not desirable to give the guided animal an exit along the entire available length. This, for example, in busy areas of a city, where there is a risk that the animal runs unchecked from the pavement to the road. In that regard, there is a need to be able to limit the freely extendable line length. This, for example, such that a dog leash with a 5-meter-long band is temporarily adjustable so that only a maximum of 2 meters of the guided animal can be freely pulled out.

In most cases, dog leashes have a blocking device with a lock button, with which the winding drum can be blocked for both winding directions. However, when the lock button is operated, the function is disabled so that the dog can take off the leash or the strap itself and the leash or strap is automatically retracted as the dog approaches the dog leash. In conventional dog collars of this kind, as for example DE 78 28 193 U1 are known, a withdrawal of the line to the full length can always be done as long as the operator does not operate the brake, ie the lock button or the locking lever. By manually depressing the lock button or a locking lever, the winding drum can be blocked, whereby the Ab- or the winding process is stopped and the present at this moment extension length is maintained until the release of the lock button or a locking lever.

Out DE 85 09 585 U1 For example, a dog hauling leash having a winding drum is known in which, for limiting the runout of a predetermined line length, a spring-loaded button serving for the control function is pressed against the surface of the leash or webbing wound on the winding drum. However, this dog leash has the disadvantage that limiting the spout is not precise and does not work reliably. In particular, there are problems when rewinding the leash. This, on the one hand, because the individual latching lugs arranged on the winding drum constantly strike a locking cam and thus cause undesired noises when a blocking position is activated. In addition, a once induced locking position of the locking cam can only be canceled by the fact that the entire line is completely rewound.

Out DE 33 15 928 A1 a Tiergurtleine with optional program switching is known in which by a slider, if desired, sometimes several different limiting positions for the lead of the line, ie their unwinding from the winding drum, can be adjusted. To adjust the leadership of the dog to the particular environment in which the dog handler and the dog are, an additional holding element in the form of gripping claw on a channel web by means of the slider on an end face of a paragraph on the webbing can be positioned. This makes it possible to allow a freewheeling of the webbing only up to a certain belt length without actuation of the slider. When this particular webbing length is reached, a piece of fabric sewn onto the webbing or a metal eyelet abuts the retaining pawl and thus prematurely stops the dog's freewheeling run prior to the end of the overall webbing length. Although this belt leash avoids the at the DE 85 09 585 U1 However, disadvantageously, it is structurally very expensive. In addition, the extended webbing by the sewn on the webbing fabric part or attached to the webbing metal eye inadvertently on objects outside the animal belt line, such as a fence, a bush or a tree or the dog leash of another dog, hooked.

It is therefore an object of the present invention to provide a device of the type described above, which has a precise and reliable stopping device.

The object is achieved by a device of the type mentioned, which is characterized in that the stopping device has a relative to the housing movably mounted base member on which the locking element is movably mounted.

The invention has the very special advantage that a precise and reliable transfer of the locking element from a release position into a blocking position and / or from a blocking position into a release position is made possible. Here, as will be explained in more detail below, the stopping device, for example, as a blocking device with which the winding drum by manual operation, at least for the unwinding and especially for both winding directions, temporarily blocked, or as, in particular automatically working, reducing device for limiting the be formed freely extendable length of the leash or the band.

In a particular embodiment, the movably mounted base part is formed as a lever pivotally mounted relative to the housing. Alternatively or additionally, it can also be provided that the movably mounted base part is mounted on the housing, in particular pivotally. In particular, the movably mounted base part can be pivotably mounted about a pivot axis, which is aligned parallel to the axis of rotation of the winding drum. Such an embodiment is particularly easy to implement, for example by a bearing pin is present on the inside of the housing, on which the base part is fixed rotatably.

Alternatively or in addition to a pivot bearing, the movably mounted base part may also be displaceable, in particular linearly displaceable, relative to the housing.

In a particularly advantageous embodiment, the stopping device is coupled or coupled to the winding coupling such that at least part of the kinetic energy, in particular the entire kinetic energy, for transferring a blocking element from a release position to a blocking position and / or from a blocking position to a release position of the Winding drum is transferred to the locking element. Such a design has the very special advantage that sufficient energy is available in order to be able to accomplish a switching operation from the release position to the blocking position or vice versa from the blocking position to the release position, in particular quickly and precisely over short switching paths.

In particular, this can advantageously be provided that a part of the rotational energy of the winding drum, in particular directly, is used to move the components quickly and reliably, with which a transfer from the blocking position to the release position or vice versa is effected.

In a particularly advantageous embodiment, the stopping device engages the rotational energy of the winding drum directly by frictional engagement and / or by form fit on one of the cheeks of the winding drum, in particular at the same time on both cheeks of the winding drum from.

As will be explained in detail below, for example, can be advantageously provided that a portion of the rotational energy of the winding drum is used to rotate a rotatably or pivotally mounted locking element from a release position to a blocking position or vice versa from a blocking position to a release position or to swing.

In a particular embodiment, at least one driver for transmitting the kinetic energy from the winding drum to the blocking element is present. The driver can in particular be designed and arranged such that it comes into contact with the winding drum, in particular with at least one tangential peripheral surface of the winding drum, in particular in frictional contact, as soon as the thickness of the wound on the winding drum winding layers falls below a predetermined or predetermined trigger value.

In particular, can be advantageously provided in a design designed as a reduction device that the driver with a tangential peripheral surface of the winding drum, in particular with two tangential peripheral surfaces of both cheeks of the winding drum, in frictional contact occurs when it is determined via the Abtastsonde that wound on the winding drum winding layers has fallen below a predetermined or predeterminable external triggering value in terms of their thickness.

In a particular embodiment, the driver is designed as Mitnehmerrad. In particular, it can be advantageously provided that the driver is frictionally connected to the blocking element. As soon as the driver wheel comes into contact with the winding drum in this embodiment, it is set in rotation by the winding drum. Since the blocking element is in frictional contact with the driver, the rotational movement of the driver is transmitted to the blocking element and this moves from the release position to the blocking position. This can be done, for example, if the thickness of the wound on the winding drum winding layers falls below the trigger value or as soon as a user brings the driver in contact with the winding drum by pressing a button.

In particular, it can be advantageously provided that the driver, in particular relative to a housing of the device, is rotatably or pivotally mounted. For example, the driver can be mounted rotatably or pivotably on a lever pivotably mounted relative to the housing be. In a particularly advantageous embodiment, the driver is rotatably or pivotably mounted on the same shaft and / or about the same axis as the blocking element.

In a particular embodiment, the driver is rotatably or pivotally mounted. In particular, it can be advantageously provided that the driver is rotatably or pivotably mounted on the base part, and / or that the driver is rotatably or pivotally mounted on the same shaft and / or about the same axis as the blocking element.

In order to ensure that a sufficiently good frictional contact between the driver and the winding drum can be produced, is provided in a particular embodiment that the driver at least in the area in which he comes into contact with the winding drum made of an elastic material and / / or of a material which allows a high coefficient of friction to the winding drum, in particular made of rubber. Alternatively, of course, it can also be provided that the winding drum in the region in which it comes in contact with the driver, having such a coating.

In order to prevent that the blocking element automatically moves accidentally from the release position into the blocking position or vice versa from the blocking position to the release position, advantageously, in particular frictionally coupled, locking means may be present. The locking means may for example comprise a spring-loaded bolt which is frictionally in operative contact with the rotatably mounted shaft of the locking element. The frictional contact is preferably selected such that it can be easily overcome at a desired switching from the release position to the blocking position or vice versa from the locking position to the release position, but at least so great that an unwanted movement of the locking element, for example due to hand movements of the device holding user is excluded.

As already mentioned, advantageously, a manually operable trigger can be present, with which the driver can be brought into operative contact with the winding roller. This in particular if the stopping device is designed as a blocking device.

Alternatively or additionally, an automatically operating trigger may be present, with which the driver can be brought into operative contact with the winding roller. This in particular if the stopping device is designed as a reducing device. In particular, an automatically operating trigger may be present, which brings the driver into operative contact with the winding roll as soon as a predetermined or predeterminable extension length of the line or the band has been pulled out, and / or as soon as the thickness of the wound on the winding drum winding layers a predetermined or predetermined trigger value below.

As already mentioned, the stopping device can be designed in particular as a selectively switchable on and off reduction device for limiting the freely extendable length of the leash or the band.

The device according to the invention can advantageously be switched into a limiting mode in which it behaves reliably like a device with a shorter line or shorter band. The animal can move freely in this limiting mode as usual and in particular pull the leash or the band against the force of the return spring, wherein only the radius of movement is reduced. If the limit mode is switched off, the full length of the leash or the band is available again.

Preferably, when the reducing device is switched off during a unwinding process, the entire line or the entire strip can be unwound, while with the reducing device switched on, only a part of the line or of the strip, in particular a part with a length of 2 meters, can be unwound.

In a particularly advantageous embodiment, the freely extendable length of the leash or the band is automatically and in particular limited without further action by the user by the switched-Reduziervorrichtung. This has the advantage that the activated limit mode does not require a change in the behavior of the user when handling the device.

Preferably, the device is designed such that, in spite of active extraction limitation, a retraction of the line or the band is made possible. In the described particular can be advantageously provided that when winding the rotational energy of the rotating in the opposite direction winding drum (winding) is partially used to switch the locking element again from the blocking position to the release position. This can be done in particular by the fact that the driver, which is still in frictional contact with the winding drum, is now driven in the opposite direction to rotate and therefore in turn rotates the frictionally coupled thereto locking element from the blocking position back into the release position.

This embodiment has the very special advantage that the leash can be retracted without the locking lugs permanently abut the locking cams of the locking element and thereby cause disturbing noises. Rather, the linen feeder can advantageously be the same as if the reducer was switched off or not available.

In a particularly advantageous embodiment, the stopping device designed as a reducing device has a scanning device for mechanically scanning the thickness of the winding layers wound onto the winding drum. In this way it can be reliably determined how much line or how much band has already been pulled out.

The scanning device may advantageously have at least one wheel, which rolls on the outside of the outermost layer of the wound on the winding drum winding layers during winding and / or unwinding.

Such a design has the very special advantage that the winding layers wound up by the scanning device for mechanical scanning of the thickness of the winding layers wound on the winding drum exert only a very slight friction and therefore at most a very small braking effect on the winding drum. This has the further advantage that the entire line or the entire band - even starting from short extension lengths - easily rewound without a particularly strong return spring must be used. Rather, the same return springs can be used as they are also used in dog collars without pullout limit.

Advantageously, no or at most a very low friction occurs between the line or the band and the wheel, since the wheel rolls on the respectively outermost layer of the line or of the band. The storage of the wheel itself plays in terms of friction in practice, no essential role, since the wheel, for example, by the use of a rolling bearing or a plain bearing, can be stored frictionless without great technical effort.

In an advantageous embodiment, the wheel is rotatably mounted about an axis which is arranged parallel to the axis of rotation of the winding drum. In this way, it is ensured that the wheel can roll smoothly and largely without friction on the outermost layer of the wound on the winding drum leash or on the outermost layer of the wound on the winding drum belt.

In a particularly advantageous embodiment, a spring device is provided which presses the wheel and / or the scanning probe against the outer layer of the winding layers wound on the winding drum. Such a spring device may for example have a leg spring. In particular, can be advantageously provided that the spring device comprises a leg spring, wherein a spring leg on the housing and another spring leg on a pivotally mounted sensing lever, at the free end of the wheel is arranged, is supported. In particular, it can be advantageously provided that the force with which the spring device pushes the wheel and / or the scanning probe against the outermost layer of the winding layers wound on the winding drum, in particular by means of a Einstellhandhabe the device is adjustable. The Einstellhandhabe may be formed, for example, as a knob or as a pivotally mounted adjustment lever.

As an alternative or in addition to a scanning of the thickness of the winding layers wound on the winding drum, it can also be provided that the reducing device has a scanning device for mechanically scanning the radial position of a probe head displaceably mounted in a spirally wound guide track. For example, the guideway may be formed as a groove in one of the end faces of the winding drum. The radial position is a reliable measure of how many rotations the winding drum has completed since the start of an extraction process and thus a reliable measure of how much line or how much band has already been processed.

In a particularly advantageous manner it can be provided that the base part is part of the scanning device and / or that the base part is designed as a movably mounted scanning probe, in particular as a scanning lever. Such an embodiment allows a particularly effective and reliable switching of the locking element.

In a particular embodiment, the scanning device has a movably mounted scanning probe, in particular a scanning lever.

In an advantageous embodiment, the scanning device has a movably arranged scanning probe, at the scanning end of which the already mentioned wheel is arranged. In particular, can be advantageously provided that the scanning device has a pivotally mounted sensing lever, at the free end of the wheel is rotatably mounted. The scanning lever may be pivotably mounted on the housing, for example. A movably mounted scanning probe, in particular in the form of a pivotally mounted scanning lever, has the very special advantage that depending on the Position of the scanning probe a switching operation can be triggered. As already mentioned, in particular the base part can be designed as a scanning lever.

As will be described in detail below, it can be provided in particular that the blocking element, in particular mechanically, is coupled to the scanning probe and switched into a blocking position as soon as the thickness of the wound layers wound on the winding drum falls below a predetermined or specifiable triggering value or as soon as possible the probe reaches a predetermined or predeterminable radial position.

In particular, the wheel can be mounted rotatably about an axis which is arranged parallel to the axis of rotation of the winding drum.

In a particular embodiment, the blocking element is mechanically coupled to the scanning probe, which may be formed in particular by the base part. In particular, it can be advantageously provided that the blocking element - directly or indirectly - is coupled to the scanning probe, in particular in the form of a scanning lever, and is switched, in particular automatically, depending on the position of the scanning probe in the blocking position or in the release position.

In a particularly advantageous embodiment, the blocking element is rotatable or pivotable on the pivotally mounted scanning lever, which may be formed in particular by the base part arranged. Such a design allows a particularly compact and reliable coupling of the blocking element to the scanning probe.

As already mentioned, it can be advantageously provided that the blocking element is coupled to the scanning direction in such a way that it automatically switches into the blocking position as soon as the thickness of the winding layers wound on the winding drum falls below a predetermined or predefinable release value. In addition, it may be advantageous to automatically switch to the release position as soon as the thickness of the wound on the winding drum winding layers exceeds the predetermined or predetermined trigger value again.

The coupling can be realized in particular in such a way that the driver, in particular directly, on the scanning probe, in particular on a pivotable scanning lever, is fixed, so that this together with the Abtasthebel depending on the thickness of the wound on the winding drum winding layers or in Dependence of the radial position of a probe is moved in a spirally wound guideway.

The trajectory and the extent of the movement can advantageously be chosen so that the driver comes into contact with the winding drum as soon as the thickness of the winding layers wound on the winding drum falls below the triggering value. In particular, it can also be provided that the driver, in particular automatically, comes out of active contact with the winding drum as soon as the thickness of the winding layers wound on the winding drum exceeds the predetermined triggering value.

Alternatively it can be advantageously provided that the driver comes into contact with the winding drum as soon as a predetermined or predeterminable radial position of a probe is achieved in a spirally wound guideway. It can be advantageously provided that the wheel rolls in the spirally wound guideway.

As already mentioned, it can be advantageously provided that the reducing device blocks the rotatability of the winding drum-in particular exclusively for the unwinding direction-as soon as the thickness of the winding layers wound on the winding drum falls below a predetermined or predefinable release value. In addition, it may be advantageously provided that the blockage of the rotatability is canceled again as soon as the thickness of the wound on the winding drum winding layers exceeds the predetermined or predetermined trigger value again. Once the trigger level is reached, further unwinding is effectively prevented so that the animal can not move further from the device. In this case, however, it may be provided that automatic winding is still possible, so that the animal can approach the device again, without the extended part of the line or the band sagging.

In a particularly advantageous embodiment, the trigger value can be set by the user, for example with a knob. In this way it is possible to set the extension limit to different lengths as needed. For example, it is possible to limit the extension length to a length of one meter by setting a first setting, for example, when a dog is to be guided close to the dog handler. In a second setting, for example, the maximum extension length can be limited to two meters, for example, to comply with legal requirements in the city. Apart from the fact that even more settings for the length of the maximum linen extension can be provided, the user can of course also turn off the stopper designed as a reduction, then to the full extension length, for example, three meters or five meters to be able to dispose of the wound on the winding drum leash or wound on the winding drum band.

In a particularly advantageous embodiment, the distance and / or the radial distance between the wheel and the driver, in particular in different locking steps adjustable. Such a design has the particular advantage that can be adjusted by adjusting the distance and / or radial distance of the trigger value. In this way it is possible to set different maximum extension lengths. In particular, it may be advantageously provided that the distance and / or the radial distance between the wheel and the driver, in particular in different latching steps is variable, so that the driver depending on the setting of the distance and / or the radial distance at a different thickness of the scanned winding position the winding drum comes into contact.

As already mentioned, the stopping device can advantageously be designed as a blocking device, with which the winding drum, in particular at any extension length, by manually pressing a button, can be blocked. Alternatively or additionally, the stopping device may be formed as a blocking device, with which the winding drum at any extension length, by manually pressing a button, at least for the unwinding direction, in particular for both winding directions, can be blocked.

In a particular embodiment stopping device is designed as a blocking device with which the winding drum at any extension length by manually pressing a button is blockable only for the unwinding can be blocked. However, the blocking device, in particular by means of a slide switch, can be switched to a special blocking mode in which the winding drum is also blocked for the winding direction.

It can be provided in particular that the device has a manually operable button, in particular a pivotally mounted button lever, with which the user can trigger a blocking of the winding drum. For example, the base part with a manually operable button, in particular a pivotally mounted button lever, such - in particular resiliently - be coupled, that the base part is set by actuation of the key in motion. Alternatively, it can also be provided that the base part is designed as a manually operable button, in particular as a pivotally mounted button lever. It is also possible that the device has a manually operable button, in particular a pivotally mounted button lever, with which a driver for transmitting the kinetic energy to the blocking element in active coupling with the winding drum bring is bar.

In a particularly advantageous embodiment, the device has a manually operable button, in particular a pivotally mounted button, which is coupled via a coupling spring with the driver and / or with the base part. Such a design has the very special advantage that it does not interfere with engagement, in particular snagging occurs when the locking cams of the locking element accidentally do not engage in the space between two locking lugs of the winding drum, but the switching movement of the locking cam is executed precisely at the moment , When locking cam and latch are just radially opposite each other. In this case, it is ensured by the coupling spring, that the locking cams of the locking element is pressed into the space between two locking lugs, as soon as the winding drum has rotated slightly further and thus locking cams and locking lugs are no longer radially opposite each other. In addition, the movements of the locking cam are not transmitted or at least in a reduced form on the button, so that the user is not disturbed by a moving button or even unsure.

The blocking element can advantageously be designed in such a way that it engages in the blocking position in at least one of a plurality of latching lugs arranged on the winding drum.

The blocking element may have a locking cam which is in operative contact with one of the locking lugs of the winding drum in the locking position. In particular, the blocking element may also have a plurality of locking cams, which are in operative contact in the blocking position with the latching lugs of the winding drum.

In particular, it can be advantageously provided that the blocking element is aligned in the release position such that the locking cams outside the range in which latching lugs of the winding drum move during winding and unwinding, are.

In a particular embodiment, at least one stopper is provided which blocks the mobility of the blocking element in such a way that it can not be rotated out of the blocking position by the winding drum.

The latching lugs can advantageously be arranged in particular at least on one of the axial end faces of the winding drum. In particular, it is advantageous if the latching lugs on the axial End face of the winding drum at the peripheral edge, in particular distributed equidistantly, are arranged.

Of particular advantage is an embodiment in which the latching lugs are arranged on both axial end faces of the winding drum, wherein the blocking element has both locking cams which engage in the latching lugs on the first side, as well as locking cams which engage in the latching lugs of the second end face , Such a design has the very special advantage that no transverse forces act on the rotational support of the winding drum, which could tilt the winding drum and / or could lead to premature wear of the winding drum bearing.

In a particularly advantageous embodiment, the blocking element is mounted relative to the winding drum against the force of a return spring, which may be formed in particular as the coupling spring mentioned above, movable. Such a design has the very special advantage that it does not interfere with engagement, in particular snagging occurs when the locking cams of the locking element accidentally do not engage in the space between two locking lugs of the winding drum, but the switching movement of the locking cam is executed precisely at the moment , When locking cam and latch are just radially opposite each other. In this case, it is ensured by the return spring, that the locking cams of the locking element is pressed into the space between two locking lugs, as soon as the winding drum has rotated slightly further and thus locking cams and locking lugs are no longer radially opposite each other.

In a particular embodiment, in addition to the stopping device, a further stopping device is provided, wherein the stopping device is designed as selectively on and off reducer for limiting the freely extendable length of the leash or the band, and wherein the further stopping device is designed as a blocking device with the the winding drum, in particular at any extension length and / or in particular for both winding directions, by manually pressing a button, can be blocked.

However, it can also be provided that there are two stopping devices, namely a reducing device and a blocking device, wherein only one of the two stopping devices is designed as described above, while the other stopping device is formed according to the prior art.

In the drawing, the subject invention is exemplified and shown schematically and will be described with reference to the figures below, wherein the same or equivalent elements are usually provided with the same reference numerals. Showing:

9 another embodiment of a device according to the invention, in which the stopping device is designed as a blocking device.

1 shows a detailed view of an embodiment of a device according to the invention, in which the stopping device as a reducing device 3 is designed to limit the freely extendible length of the band. The device has a winding drum rotatably mounted relative to a housing (not shown) 1 on top of that, a band 2 aufwickelbar and against the restoring force of a (not shown) spring device is unwound. The spring device may for example be formed as a spiral spring, which is inside the winding drum 1 is arranged and on the one hand on a shaft 11 on which the winding drum 1 is rotatably mounted, and on the other hand on the winding drum 1 supported.

The device according to the invention has a reducing device 3 to limit the free extendible length of the band 2 on. The reducer 3 includes a scanning device 4 for mechanically sensing the thickness of the winding drum 1 wound up winding layers of the tape 2 ,

The scanning device 4 includes a movably mounted scanning probe, namely a relative to the housing about a pivot axis 5 pivotally mounted base part 31 namely a stored scanning lever 6 , At the free end of the scanning lever 6 is a wheel 7 rotatably mounted, that when winding and / or unwinding on the outermost layer 8th the on the winding drum 1 rolled up winding layers rolls.

The reducer 3 also includes a thigh spring 9 that the scanning lever 6 including his bike 7 , the extreme situation 8th suppressed. For this the leg spring is supported 9 on the one hand on a housing-fixed bearing 10 and on the other hand indirectly on the scanning lever 6 which will be described in detail below.

To turn off the reducer, the scan lever will pivot about the pivot axis 5 pivoted so that the wheel 7 no longer in contact with the outermost bearing 8th which stands on the winding drum wound up winding layers. In this disengaged position, the reducer is rusted if there is no limit to the freely extendable length of the band 2 is desired. This, for example, if it is desired to run a guided animal, especially a dog, for example, in the forest or in a park until the entire band is unwound from the winding drum.

To turn on the reducer is to cancel the locking of the scanning 6 pivoted to the winding drum out so that the wheel on the outermost layer 8th which can roll wound on the winding drum winding layers. During the rolling process, the radial distance of the free end of the scanning lever is reduced 6 from the axis of rotation 11 the winding drum 1 the more, the more volume 2 from the winding drum 1 is unwound because of the thickness of the winding drum 1 wound up winding layers by unwinding the tape 2 decreases.

If so much tape 2 from the winding drum 1 has been wound that one rotatable about an axis of rotation 12 stored driver 13 with the tangential outside 14 the winding drum 1 comes into contact, so is the Mitnehmerrad 15 trained drivers 13 in turn set in rotation. In that regard, a part of the kinetic energy of the winding drum on the Mitnehmerrad 15 transfer.

The Mitnehmerrad 15 is in frictional contact with a blocking element 16 that has a locking cam 17 having. The blocking element 16 is also about the second axis of rotation 12 rotatably mounted. By the frictional engagement between the Mitnehmerrad 15 and the blocking element 16 becomes the blocking element 16 from the rotated Mitnehmerrad 15 from the in 1 shown release position transferred into a locked position in which the locking cam 17 with the locking lugs 18 the winding drum 1 comes into operative contact and thereby the winding drum 1 clocking. This process is in 2a shown.

When the guided animal approaches the device again, the winding drum becomes 1 from the (not shown) spring device for winding the tape 2 automatically turned in the opposite direction, which also causes the Mitnehmerrad 15 is rotated in the opposite direction. The Mitnehmerrad 15 thus pivots the frictionally coupled with him blocking element 16 back to the release position. This has the advantage that the band can continue to be wound up as the animal continues to approach the device without the blocking element 16 in conflict with one of the locking lugs 18 occurs, this will be in 2 B shown.

2c shows a radial plan view of the in 2a represented parts.

In 2c it can be seen that the driver 13 a first Mitnehmerrad 15a and a second Mitnehmerrad 15b has, wherein the first Mitnehmerrad 15a is designed and arranged with the tangential outside of a first winding drum cheek 19 to contact while the second Mitnehmerrad 15b is formed and arranged with the tangential outer side of the second winding drum cheek 20 to get in touch.

2c also shows that the blocking element 16 a first blocking element part 16a and a second blocking element part 16b has, which are rotatably connected to each other and the respective locking cams 17 exhibit. The locking cams 17 of the first blocking element part 16a are designed and determined to come into operative contact with the locking lugs on the first winding drum cheek 19 are arranged while the locking cams 17 of the second blocking element part 16b are designed and arranged with the locking lugs 18 the second winding drum cheek 20 to come into operative contact when the thickness of the wound on the winding drum winding layers falls below a predetermined triggering value, so that the driver 13 in contact with the winding drum 1 occurs.

2d shows an axial section through the device in the in 2a shown active position of reducer 3 , namely in the locked position. In the central interior 21 the winding drum 1 can the initially mentioned (not shown) spring device, against the restoring force of the band 2 from the rotatably mounted winding drum 1 unwindable, be arranged.

3 shows an axial cross-sectional view through the reducing device 3 , As already mentioned, the leg spring is supported 9 on the one hand on a housing-fixed bearing 10 from. The other leg of the leg spring 9 moves over a bolt 23 on a connecting shaft 23 between the first blocking element part 16a and the second (not shown in this figure) second blocking element 16b , The bolt 22 stands in frictional contact with the connecting shaft 23 so that the blocking element 16 can only be rotated by overcoming this frictional force. This has the very special advantage that the blocking element 16 can not unintentionally turn from the release position into the blocking position or from the blocking position to the release position. In that regard, it is advantageously avoided that the blocking element 16 adjusted by its inertia when the user jerks the hand-held device and jerks in particular rotates.

4 shows a further embodiment of a device according to the invention, which is a reducing device 3 has, as its sampling 6 trained base part 32 a first sensing leg 24 and a second scanning leg 25 having. The first scanning leg 24 and the second scanning leg 25 are hinged together, the angular position of the first Abtastschenkel 24 and the second sensing leg 25 by means of an adjusting lever 26 can be adjusted. The scanning lever 6 has a locking device 27 on, the engagement of the first Abtastschenkels 24 relative to the second sensing leg 25 allowed in three different positions. Each of the different locking positions is a different radial distance of Mitnehmerrades 15 to the winding drum 1 assigned, so that in each case a different thickness of the on the winding drum 1 wound up winding layers of the tape 2 each defines a different trigger value for switching from the release position to the blocking position. Until the Mitnehmerrad 15 with the winding drum 1 must come into operative contact yes after adjustment of the adjusting lever 26 the more volume 2 from the winding drum 1 be handled, the larger the original radial distance was at fully wound tape.

4 shows a detent adjustment of the scanning lever 6 for a smaller maximum extendable length of leash while 5 a setting of the scanning lever 6 the detent position for a relatively larger maximum extension length of the tape shows.

6 shows in a schematic cross-sectional representation of the further embodiment of the device according to the invention with a schematically indicated housing 28 , On the outside of the housing are different setting values "1", "2" and "3" for different settings of a setting pointer 28 which the user can pan marks. Depending on the swivel position of the adjustment hand 29 are the first scanning leg 24 and the second scanning leg 25 rusted relative to each other in different positions, so that in each case a short, a medium or a large extension limit is set.

7 another embodiment of a device according to the invention. In this device, unlike those in the 1 to 6 shown devices, not the thickness of the winding drum 1 wound winding layers scanned to determine how much tape has already been unwound, but the radial position of one in a spirally wound guideway 31 slidably mounted probe 30 , The guideway 31 is as a groove in one of the end faces of the winding drum 1 educated. The radial position of the probe 30 is a reliable measure of how many rotations the winding drum 1 Since the beginning of an extraction process has completed and thus a reliable measure of how much tape 2 has already been settled.

Depending on the radial position, in particular the radial distance of the probe 30 from the axis of rotation 11 the winding drum 1 , A blocking element not shown in this figure for the sake of clarity is shown 16 switched into a blocking position as soon as the probe 30 a predetermined or predeterminable radial distance to the axis of rotation 11 the winding drum 1 below. Also for this purpose, a part of the kinetic energy, in particular the entire kinetic energy, for the transfer of a blocking element 16 from the release position into the blocking position of the winding drum 1 on the blocking element 16 transfer. This can also be done in this embodiment, for example, as above with respect to the 1 to 6 is described.

8a shows an embodiment of a device according to the invention, in which the stopping device as a blocking device 33 is trained. The blocking device 33 has a base part 32 on, that around a swivel axis 5 is pivotally mounted.

The base part 32 can against the force of a return spring, not shown in this figure by means of a button, not shown, from a rest position (dashed lines) in the direction of the winding drum 1 be pivoted so far until a rotatable about an axis of rotation 12 stored driver 13 with the tangential outside 14 the winding drum 1 comes into contact, so is the Mitnehmerrad 15 trained drivers 13 in turn set in rotation. In that regard, a part of the kinetic energy of the winding drum on the Mitnehmerrad 15 transfer.

The Mitnehmerrad 15 is in frictional contact with a blocking element 16 that has a locking cam 17 and the movable on the base part 32 is stored. The blocking element 16 is also about the second axis of rotation 12 rotatably mounted. By the frictional engagement between the Mitnehmerrad 15 and the blocking element 16 becomes the blocking element 16 from the rotated Mitnehmerrad 15 transferred from the release position, not shown in the illustrated blocking position in which the locking cam 17 with the locking lugs 18 the winding drum 1 comes into operative contact and thereby the winding drum 1 clocking.

When the guided animal approaches the device again, the winding drum becomes 1 from a (not shown) spring device for winding the tape 2 automatically turned in the opposite direction, which also causes the Mitnehmerrad 15 is rotated in the opposite direction. The Mitnehmerrad 15 thus pivots the frictionally coupled with him blocking element 16 back to the release position. This has the advantage that the band can continue to be wound up as the animal continues to approach the device without the blocking element 16 in conflict with one of the locking lugs 18 occurs.

8b shows a sectional view along in 8a Plotted cutting plane AB. In the sectional view is to recognize that the blocking element 16 is constructed in two parts and a first blocking element part 16a , as well as a second blocking element part 16b having. Both the blocking element part 16a , as well as the second blocking element part 16b each have a shaft part in the driver 13 protrudes, leaving the blocking element 16 relative to the driver 13 is rotatably mounted. The first blocking element part 16a and the second blocking element part 16b be from a tension spring 34 pulled towards each other, so that the driver 13 between the blocking element part 16a and the second blocking element part 16b is trapped and so creates a frictional connection. The frictional engagement allows a torque from the driver to the blocking element 16 can be transferred.

9a shows another embodiment of a device according to the invention, in which the stopping device as a blocking device 33 is trained.

The blocking device 33 has a base part 32 on, that around a swivel axis 5 is pivotally mounted.

The base part 32 can against the force of a return spring 9 by means of an actuating button 35 that against the base part 32 is pivotable, from the rest position shown in the direction of the winding drum 1 be pivoted so far until a rotatable about an axis of rotation 12 stored driver 13 with the tangential outside 14 the winding drum 1 comes into contact, so is the Mitnehmerrad 15 trained drivers 13 in turn set in rotation. In that regard, a part of the kinetic energy of the winding drum on the Mitnehmerrad 15 transfer.

The Mitnehmerrad 15 is in frictional contact with a blocking element 16 that has a locking cam 17 and the movable on the base part 32 is stored. The blocking element 16 is also about the second axis of rotation 12 rotatably mounted. By the frictional engagement between the Mitnehmerrad 15 and the blocking element 16 becomes the blocking element 16 from the rotated Mitnehmerrad 15 transferred from the release position, not shown in the illustrated blocking position in which the locking cam 17 with the locking lugs 18 the winding drum 1 comes into operative contact and thereby the winding drum 1 clocking.

When the guided animal approaches the device again, the winding drum becomes 1 from a (not shown) spring device for winding the tape 2 automatically turned in the opposite direction, which also causes the Mitnehmerrad 15 is rotated in the opposite direction. The Mitnehmerrad 15 thus pivots the frictionally coupled with him blocking element 16 back to the release position. This has the advantage that the band can continue to be wound up as the animal continues to approach the device without the blocking element 16 in conflict with one of the locking lugs 18 occurs.

9b shows that the lock button is still a locking slide 36 Having, along a Arretierweges 37 can be moved into a locked position. In this locking position, the in 9b is shown blocks a locking projection 38 of the locking slide 36 turning back the locking element 16 in the release position. The blocking element 16 has a locking cam 39 on, at the blocking tab 38 abuts when the locking slide 36 is moved into the locked position.

When the guided animal approaches the device again, the winding drum becomes 1 from the spring device for winding the tape 2 no longer turned in the opposite direction. Rather, the winding drum 1 blocked in both directions when the locking slide 36 is moved into the locked position. The band 2 is not retracted in this position. To the locking slide 36 to be able to move into the locked position, the operation key must 35 be pressed first.
