Abstract

The invention relates to a traction device which produces large transmission when the tension of the traction cable is reduced and/or is zero, such that during rotation of a handwheel, lengths of the traction cable can vary significantly. As soon as the tension of the traction cable exceeds a threshold value, the clamping device produces transmission in a slow manner such that rotation of the handwheel produces comparatively small variations of the length of the traction cable and enables the clamping force to be adjusted in a delicate manner.

Description

Die Erfindung bezieht sich auf eine Spannvorrichtung für Zugkabel, insbesondere von Zugkabel-Schnürungen an Schuhen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a tensioning device for tension cables, in particular tension cable laces on shoes, according to the preamble of claim 1.

Schuhe mit Zugkabel-Schnürungen und zugeordneten Spannvorrichtungen, die mittels eines Handrades betätigt werden, sind auf dem Markt erhältlich.Shoes with pull cord laces and associated tensioners operated by a handwheel are available on the market.

Bei diesen Spannvorrichtungen sind einerseits Konstruktionen bekannt, bei denen das Handrad zumindest bei Drehung in der zur Erhöhung der Spannung des Zugkabels vorgesehenen Drehrichtung unmittelbar mit der Kabeltrommel zwangsgekoppelt ist und die Kabeltrommel dementsprechend gleiche Drehwinkel wie das Handrad ausführt. In diesem Zusammenhang kann beispielhaft auf die EP 0 651 954 B1 , die EP 0 540 251 A1 sowie die AT-PS 195 751 verwiesen werden. Bei derartigen Konstruktionen ist vorteilhaft, dass mit vergleichsweise geringer Drehverstellung des Handrades eine größere Veränderung der Länge des Zugkabels erreichbar ist.In these clamping devices on the one hand constructions are known in which the handwheel is forcibly coupled directly to the cable drum at least during rotation in the direction provided for increasing the tension of the tensioning cable and the cable drum accordingly performs the same rotation angle as the handwheel. In this context can be exemplified on the EP 0 651 954 B1 , the EP 0 540 251 A1 as well as the AT-PS 195 751 to get expelled. In such constructions is advantageous that with a relatively small rotational adjustment of the handwheel, a larger change in the length of the pull cable can be achieved.

Andererseits sind auch Spannvorrichtungen bekannt, bei denen zwischen Handrad und Kabeltrommel ein Getriebe angeordnet ist, welches die Drehbewegungen des Handrades ins Langsame übersetzt. Bei Verkürzung des Zugkabels führt also die Kabeltrommel relativ zum Handrad einen deutlich verminderten Drehhub aus. Hinsichtlich solcher Konstruktionen kann beispielhaft auf die US 4,961,544 , die US 6,202,953 B1 sowie die US 6,289,558 B1 verwiesen werden. Vorteilhaft an solchen mit Getriebe versehenen Spannvorrichtungen ist, dass auch sehr kleine Längenänderungen des Zugkabels und dementsprechend geringfügige Änderungen der Zugspannung leicht einstellbar sind.On the other hand, clamping devices are known in which a gear is arranged between the handwheel and the cable drum, which translates the rotational movements of the handwheel slower. When shortening the Zugkabels thus leads the cable drum relative to the handwheel significantly reduced rotational stroke. With regard to such constructions can be exemplified in the US 4,961,544 , the US 6,202,953 B1 as well as the US 6,289,558 B1 to get expelled. An advantage of such provided with gear tensioners is that even very small changes in length of the tension cable and, accordingly, minor changes in tension are easily adjustable.

Die Firma BOA Technology, Inc. bietet auch mit Planetengetriebe versehene Spannvorrichtungen an, so dass trotz des Getriebes nur ein geringes Bauvolumen benötigt wird.BOA Technology, Inc. also offers planetary-geared tensioners, so that despite the gearbox, only a small amount of space is required.

Aus der US 4,748,726 ist eine Spannvorrichtung gemäß dem Oberbegriff des Anspruches 1 bekannt. Eine derartige Konstruktion ist vorteilhaft, weil zwischen Handrad und Kabeltrommel bzw. Kabeltrommeln zwei Antriebsverbindungen vorgesehen sind, und zwar eine nur zur Erzielung geringer Spannkräfte geeignete Kraftschlussverbindung sowie eine prinzipiell für beliebig hohe Spannkräfte geeignete Formschlussverbindung.From the US 4,748,726 a tensioning device according to the preamble of claim 1 is known. Such a construction is advantageous because between the handwheel and cable drum or cable drums two drive connections are provided, namely a suitable only to achieve low clamping forces frictional connection and a principle suitable for arbitrarily high clamping forces positive connection.

Die Formschlußverbindung weist relativ zur Kraftschlußverbindung eine Übersetzung ins Langsame auf, so dass bei losem Spannkabel zunächst die Kraftschlußverbindung wirksam wird und eine schnelle Beseitigung der Lose des Spannkabels ermöglicht, während danach bei Überschreitung eines durch den Kraftschluß vorgegebenen Schwellwertes der Spannkraft automatisch die Formschlußverbindung wirksam wird und eine sehr feinfühlige Einstellung der gewünschten Spannkraft ermöglicht. Zur Verwirklichung dieses Konzeptes kann das die Formschlußverbindung verwirklichende Getriebe derart ausgebildet sein, dass die Kabeltrommel bzw. den Kabeltrommeln ein in Spannrichtung wirksamer, durch begrenzte Kräfte gehemmter Freilauf zugeordnet ist.The positive connection has relative to the frictional connection on a translation to the slow, so that in loose tension cable first the frictional connection is effective and a quick elimination of the lots of the tensioning cable allows, while thereafter when exceeding a predetermined by the frictional threshold of the clamping force automatically the positive connection is effective and allows a very sensitive adjustment of the desired clamping force. To realize this concept, the form-fitting connection realizing the transmission can be designed such that the cable drum or the cable drums is associated with a more effective in the clamping direction, inhibited by limited forces freewheel.

Aufgabe der Erfindung ist es nun, für eine solche Spannvorrichtung eine besonders vorteilhafte und kompakte Konstruktion aufzuzeigen. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The object of the invention is now to show a particularly advantageous and compact design for such a clamping device. This object is achieved by the characterizing features of claim 1.

Bei der Erfindung kann in besonders vorteilhafter weise der Planetenträger relativ zum Hohlrad gegen Drehung entgegen der Spannrichtung durch eine erste Sperre gesperrt und dem Hohlrad eine auslösbare zweite Sperre zugeordnet sein, die im wirksamen Zustand nur eine zur Spannrichtung des Planetenträgers gleich gerichtete Bewegung des Hohlrades zuläßt.In the invention, the planet carrier can be locked relative to the ring gear against rotation against the clamping direction by a first lock and the ring gear to be associated with a releasable second lock, which allows in the effective state only one direction of clamping the planet carrier the same direction movement of the ring gear in a particularly advantageous manner.

Insbesondere kann vorgesehen sein, dass Planetenträger und Hohlrad über die erste Sperre in deren Öffnungsrichtung mit Kraftschluß gekoppelt sind, welcher größer ist als die Hemmkräfte, die von der zweiten Sperre auf das Hohlrad bei dessen Drehung in Freilaufrichtung der zweiten Sperre ausgeübt werden.In particular, it can be provided that planet carrier and ring gear are coupled via the first lock in the opening direction with adhesion, which is greater than the restraining forces exerted by the second lock on the ring gear during its rotation in the freewheeling direction of the second lock.

Bei dieser Ausführungsform hat die erste Sperre eine Doppelfunktion:In this embodiment, the first barrier has a dual function:

Einerseits verhindert sie bei wirksamer zweiter Sperre, dass sich die Kabeltrommel bzw. Kabeltrommeln in Entlastungsrichtung des Zugkabels bzw. der Zugkabel drehen können. Andererseits bewirkt die erste Sperre einen Kraftschluß zwischen Planetenträger und Hohlrad, so dass bei geringer Zugspannung des Zugkabels bzw. der Zugkabel Sonnenrad, Planetenträger und Hohlrad gleiche und gleich gerichtete Drehungen in Spannrichtung ausführen können und dementsprechend eine Schnellverstellung des Zugkabels bzw. der Zugkabel erfolgen kann.On the one hand, it prevents with effective second lock that the cable drum or cable drums can rotate in the discharge direction of the pull cable or the pull cable. On the other hand, the first lock causes a frictional connection between the planet carrier and ring gear, so that at low tension of the pull cable or the Zugkabel sun gear, planet carrier and ring equally and identically directed rotations can perform in the clamping direction and accordingly can be done a quick adjustment of the pull cable or pull cable.

Im übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der besonders bevorzugte Ausführungsformen der Erfindung näher beschrieben werden. Der Schutzumfang ist selbstverständlich nicht auf die ausdrücklich beanspruchten oder dargestellten Merkmalskombinationen beschränkt, vielmehr wird Schutz auch für prinzipiell beliebige Unterkombinationen der Merkmale beansprucht.Moreover, reference is made with regard to preferred features of the invention to the claims and the following explanation of the drawing, are described in detail with reference to the particularly preferred embodiments of the invention. The scope of protection is of course not limited to the expressly claimed or illustrated combinations of features, but protection is also claimed for in principle any sub-combinations of the features.

  • Fig. 1 Einen schematisierten Axialschnitt einer erfindungsgemäßen Spannvorrichtung mit Planetengetriebe,
  • Fig. 2 einen schematisierten Querschnitt entsprechend der Schnittebene II-II in Fig. 1 und

In the drawing shows:
  • Fig. 1 A schematic axial section of a clamping device according to the invention with planetary gear,
  • Fig. 2 a schematic cross section corresponding to the section plane II-II in Fig. 1 and
  • Fig. 3 a schematic cross section corresponding to the sectional plane III-III in Fig. 1 ,

Innerhalb eines Gehäuses 1 ist eine Welle 2 drehgelagert, auf der außerhalb des Gehäuses 1 ein Handrad 3 und innerhalb des Gehäuses 1 ein Sonnenrad 4 eines im Gehäuse 1 untergebrachten Planetengetriebes 5 drehfest angeordnet ist. Das Planetengetriebe 5 besitzt ein auf der Welle 2 drehbar gelagertes Hohlrad 6 sowie einen ebenfalls auf der Welle 2 drehgelagerten Planetenträger 7. Dieser ist über die Achsen seiner Planetenräder 8 drehfest mit einer auf der Welle 2 drehgelagerten Kabeltrommel 9 verbunden, die ihrerseits mit Zugkabeln 10 verbunden ist.Within a housing 1, a shaft 2 is rotatably mounted on the outside of the housing 1, a handwheel 3 and within the housing 1, a sun gear 4 of a housed in the housing 1 planetary gear 5 is rotatably disposed. The planetary gear 5 has a rotatably mounted on the shaft 2 ring gear 6 and also rotatably mounted on the shaft 2 planet carrier 7. This is rotatably connected via the axes of its planetary gears 8 with a rotatably mounted on the shaft 2 cable drum 9, which in turn connected with tension cables 10 is.

Die Planetenräder 8 besitzen eine übliche Verzahnung, die mit entsprechenden Verzahnungen am Außenumfang des Sonnenrades sowie am den Planetenrädern 8 zugeordneten Innenumfangsbereich des Hohlrades 6 kämmt.The planet gears 8 have a conventional toothing, which meshes with corresponding toothings on the outer circumference of the sun gear and on the planetary gears 8 associated inner peripheral portion of the ring gear 6.

Im Axialbereich des Planetenträgers 7 ist am Innenumfang des Hohlrades 6 gemäß Fig. 3 eine sägezahnartige Verzahnung angeordnet, in die am Planetenträger 7 angeordnete bzw. angeformte Sperrklinken 11 in einer Umfangsrichtung sperrend und in der anderen Umfangsrichtung rastend eingreifen. Dementsprechend ist der Planetenträger 7 im Beispiel der Fig. 3 relativ zum Hohlrad 6 im Uhrzeigersinn undrehbar. Entgegen dem Uhrzeigersinn läßt sich der Planetenträger 7 gegen den Rastwiderstand, den die Sperrklinken 11 in der genannten Innenumfangsverzahnung des Hohlrades bewirken, relativ zum Hohlrad 6 drehen.In the axial region of the planet carrier 7 is according to the inner circumference of the ring gear 6 Fig. 3 a sawtooth-like toothing arranged in the arranged on the planet carrier 7 or molded pawls 11 engage locking in a circumferential direction and latching in the other circumferential direction. Accordingly, the planet carrier 7 in the example of Fig. 3 relative to the ring gear 6 clockwise non-rotatable. Counterclockwise, the planet carrier 7 can rotate relative to the ring gear 6 against the latching resistance caused by the pawls 11 in said inner peripheral teeth of the ring gear.

Am Außenumfang des Hohlrades 6 ist eine weitere sägezahnartige Verzahnung, die mit einer am Gehäuse 1 angeordneten, manuell auslösbaren Sperrklinke 12 zusammenwirkt. Im wirksamen Zustand der Sperrklinke 12 läßt sich das Hohlrad 6 relativ zum Gehäuse 1 im Beispiel der Fig. 3 nur entgegen dem Uhrzeigersinn drehen, d. h. die mögliche Drehrichtung des Hohlrades 6 relativ zum Gehäuse 1 ist gleich gerichtet zu der möglichen Drehung des Planetenträgers 7 relativ zum Hohlrad 6. Die durch die Sperrklinke 12 einer Drehung des Hohlrades 6 entgegen dem Uhrzeigersinn entgegen wirkende Hemmkraft ist geringer, als die Hemmkraft, welche von den Sperrklinken 11 einer Drehung des Planetenträgers relativ zum Hohlrad 6 entgegengesetzt wird.On the outer circumference of the ring gear 6 is a further sawtooth-like toothing, which cooperates with a arranged on the housing 1, manually releasable pawl 12. In the effective state of the pawl 12, the ring gear 6 can be relative to the housing 1 in the example of Fig. 3 rotate only counterclockwise, ie the possible direction of rotation of the ring gear 6 relative to the housing 1 is directed the same to the possible rotation of the planet carrier 7 relative to the ring gear 6. The by the pawl 12 counterclockwise rotation of the ring gear 6 counteracting inhibiting force is lower than the restraining force which is opposed by the pawls 11 to a rotation of the planetary carrier relative to the ring gear 6.

Die dargestellte Anordnung funktioniert wie folgt:The arrangement shown works as follows:

Bei Ansicht in Pfeilrichtung P in Fig. 1 wird das Handrad 3 zum Spannen der Kabel 10 entgegen dem Uhrzeigersinn gedreht, wenn die sägezahnartigen Verzahnungen am Außen- und Innenumfang des Hohlrades entsprechend Fig. 3 ausgerichtet sind.When viewed in the direction of arrow P in Fig. 1 the hand wheel 3 is rotated for tensioning the cable 10 in the counterclockwise direction, when the sawtooth teeth on the outer and inner circumference of the ring gear accordingly Fig. 3 are aligned.

Zunächst mögen die Kabel 10 eine Lose aufweisen, d. h. die Zugspannung der Kabel 10 ist zunächst verschwindend gering. Wenn nun das Handrad 3 entgegen dem Uhrzeigersinn gedreht wird, kann die zwischen Planetenträger 7 und Hohlrad 6 durch die Sperrklinken 11 bewirkte Hemmkraft noch nicht überwunden werden. Dementsprechend führen das Handrad 3, das Sonnenrad 4, der Planetenträger 7 sowie das Hohlrad 6 gleich gerichtete und größenmäßig gleiche Drehwinkel aus. Dies ist gleichbedeutend damit, dass die mit dem Planetenträger 7 drehfest verbundene Kabeltrommel 9 in Spannrichtung der Kabel 10 die gleiche Drehbewegung wie das Handrad 3 ausführt. Im Ergebnis kann also die Lose der Kabel 10 schnell beseitigt werden.First, the cables 10 may have a lot, i. H. the tension of the cable 10 is initially negligible. Now, if the handwheel 3 is rotated counterclockwise, the between planet carrier 7 and ring gear 6 caused by the pawls 11 inhibiting force can not be overcome. Accordingly, the handwheel 3, the sun gear 4, the planetary carrier 7 and the ring gear 6 execute the same direction and the same rotational angle. This is equivalent to the fact that the cable drum 9 rotatably connected to the planet carrier 7 in the clamping direction of the cable 10 performs the same rotational movement as the handwheel 3. As a result, therefore, the lots of the cables 10 can be eliminated quickly.

Nunmehr möge die Zugspannung der Kabel 10 einen durch die zwischen Hohlrad 6 und Planetenträger 7 vorliegende Hemmkraft bestimmten Schwellwert überschreiten. Wenn nun das Handrad 3 entgegen dem Uhrzeigersinn weiter gedreht wird, wird vom Sonnenrad 4 über die Planetenräder 8 auf das Hohlrad 6 ein hinreichend großes Drehmoment im Uhrzeigersinn übertragen, derart, dass sich das Hohlrad 6 im Uhrzeigersinn zu drehen sucht; eine solche Drehbewegung wird jedoch von der wirksamen Sperrklinke 12 verhindert, d. h. das Hohlrad 6 bleibt relativ zum Gehäuse 1 stationär. Entsprechend dem Übersetzungsverhältnis des Planetengetriebes 5 wird nunmehr der Planetenträger mit gegenüber der Drehung des Handrades 3 verlangsamter Drehung weiterbewegt, so dass auch die Kabeltrommel 9 entsprechend langsam in Spannrichtung der Kabel 10 gedreht wird. Im Ergebnis lassen sich damit die Längen und Spannkräfte der Zugkabel 10 sehr feinfühlig einstellen.Now let the tension of the cable 10 exceed a certain threshold between the ring gear 6 and planet carrier present inhibiting force. Now, if the handwheel 3 is rotated counterclockwise, a sufficiently large torque is transmitted clockwise from the sun gear 4 via the planetary gears 8 to the ring gear 6, such that the ring gear 6 seeks to turn in a clockwise direction; However, such a rotational movement is from the effective Pawl 12 prevents, ie the ring gear 6 remains stationary relative to the housing 1. According to the gear ratio of the planetary gear 5, the planet carrier is now moved with respect to the rotation of the handwheel 3 slowed rotation, so that the cable drum 9 is rotated accordingly slowly in the clamping direction of the cable 10. As a result, the lengths and clamping forces of the tension cable 10 can be adjusted very sensitively.

Wenn die Zugkabel 10 gelockert bzw. gelöst werden sollen, wird die Sperrklinke 12 entsprechend dem Pfeil Q in Fig. 3 manuell geschwenkt, so dass sich das Hohlrad 6 und damit auch die Kabeltrommel 9 im Uhrzeigersinn und dementsprechend in Entspannrichtung der Kabel 10 drehen können. Diese Drehung kann durch eine entsprechende manuelle Drehverstellung des Handrades 3 im Uhrzeigersinn unterstützt werden.If the tension cables 10 are to be loosened or loosened, the pawl 12 is in accordance with the arrow Q in Fig. 3 pivoted manually, so that the ring gear 6 and thus the cable drum 9 can rotate clockwise and accordingly in the direction of relaxation of the cable 10. This rotation can be supported by a corresponding manual rotation adjustment of the handwheel 3 in the clockwise direction.
