Date Aug. 18, 1994The object of the invention is to improve a central closing device for shoes with a rotationally supported cord disc for at least one cord-type tensioning member for closing the shoe in such a way that the number of rotations of the cord disci is limited without any increasing the space required. This object is achieved by the fact that both the cord disc (3) and a stationary member (1 or 41) each have mutually-cooperating tooth profiles (41a, 42a or 41b, 42b) having the same tooth pitch but of different diameters. Located in the intermediate space (49) created due to the different diameters of the tooth profiles (41a, 42a or 41b, 42b) is an idling pinion (43) of the same pitch, which meshes with the two tooth profiles (41a, 42a or 41b, 42b). At least one stop (46, 46') is provided to limit the travel of the idling pinion (43).

Description

Zentralverschluß für Schuhe Central lock for shoes
Die vorliegende Erfindung bezieht sich auf einen Zentral¬ verschluß für Schuhe gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a central closure for shoes according to the preamble of claim 1.
Ein derartiger, als Drehverschluß ausgebildeter Zentralver¬ schluß ist aus der EP-0 393 380 Bl bekannt. Die Begrenzung der Umdrehungszahl der Seilscheibe auf etwas weniger als zwei volle Umdrehungen ist dort durch die Anwendung des Schleppscheibenprinzips bedingt. Die eine Schleppscheibe ist hierbei durch die Seilscheibe gebildet. Diese besitzt einen Mitnehmer, der nach etwa einer Umdrehung an einem drehbaren Arm anschlagen kann, der die zweite Schleppscheibe verkörpert und der mit einem Anschlagvorsprung an einer Gehäusekante anschlagen kann. Angestrebt sind dabei geringe bauliche .Abmessungen und zwar auch dann, wenn ein langer Seilweg zum Schließen des Schuhes notwendig ist.Such a central lock designed as a rotary lock is known from EP-0 393 380 B1. The limitation of the number of revolutions of the sheave to a little less than two full revolutions is there due to the application of the traction sheave principle. One drag pulley is formed by the rope pulley. This has a driver which, after about one revolution, can strike a rotatable arm, which embodies the second drag disc, and which can strike a housing edge with a stop projection. The aim is to achieve small structural dimensions, even if a long cable route is necessary to close the shoe.
Bei dieser bekannten Vorrichtung muß der Durchmesser der Seilscheibe entsprechend dem Seilweg und den dort möglichen, nicht ganz zwei vollständigen Umdrehungen der Seilscheibe gewählt werden. Bei großen Seilwegen ist daher auch der Durchmesser der Seilscheibe entsprechend groß zu wählen. Bei dieser bekannten Vorrichtung ist man daher in der Freiheit der Wahl der Bemessung der Abmessungen dieser Vorrichtung stark eingeschränkt. Andererseits könnte durch Verwendung zusätzlicher Schlepp¬ scheiben die Umdrehungszahl der Seilscheibe erhöht werden, so daß ein größerer Seilweg durch Erhöhung der Windungszahl auf der Seilscheibe beherrschbar wäre. Dies würde jedoch eine der Dicke der zusätzlichen Schleppscheiben entsprechend größeres Bauvolumen erfordern.In this known device, the diameter of the rope sheave must be selected according to the rope path and the possible, not quite two complete turns of the rope sheave. For large rope routes, the diameter of the rope sheave should therefore be chosen accordingly. In this known device, the freedom to choose the dimensions of this device is therefore greatly restricted. On the other hand, the number of revolutions of the rope sheave could be increased by using additional drag disks, so that a larger rope path would be manageable by increasing the number of turns on the rope sheave. However, this would require a larger construction volume corresponding to the thickness of the additional drag disks.
Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, einen Zentralverschluß der eingangs erwähnten Art, d.h. mit einer Begrenzung der Umdrehungszahl der Seilscheibe, so zu verbessern, daß ohne Vergrößerung des Bauvolumens eine Erhöhung der zu begrenzenden Umdrehungszahl der Seilscheibe ermöglicht wird.The object of the present invention is to achieve a central lock of the type mentioned at the outset, i.e. with a limitation of the number of revolutions of the rope sheave, so that an increase in the number of revolutions of the rope sheave to be limited is made possible without increasing the construction volume.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with the features of claim 1.
Durch die auf dem Prinzip eines Planetentriebes aufbauende Begrenzungseinrichtung der Umdrehungszahl der Seilscheibe ist es durch die Wahl des Übersetzungsverhältnisses des Getriebes sowie durch die Anordnung des bzw. der Anschläge(s) in einfacher Weise möglich, die Umdrehungszahl der Seilscheibe unabhängig von äußeren Abmessungen in relativ weiten Bereichen, beispielsweise in einem Verhältnis zwischen 2:1 bis 10:1, zu wählen. So kann durch Veränderung, beispielsweise Vergrößerung des Durchmessers der Zahnung der Seilscheibe und entsprechende Veränderung, beispielsweise Verkleinerung des Durchmessers des freilaufenden Zahnrades, ein vorgegebener Zentralverschluß mit an den jeweiligen Verwendungszweck angepaßten Übersetzungsverhältnissen hergestellt werden, ohne daß sonstige bauliche Veränderungen notwendig werden.Due to the principle of a planetary gear limiting device for the number of revolutions of the sheave, it is possible in a simple manner through the choice of the transmission ratio of the transmission and through the arrangement of the stop (s), the number of revolutions of the sheave to a relatively large extent regardless of external dimensions Ranges, for example in a ratio between 2: 1 to 10: 1. Thus, by changing, for example increasing the diameter of the toothing of the sheave and corresponding changes, for example reducing the diameter of the free-running gear, a predetermined central lock can be produced with gear ratios adapted to the respective intended use, without any other structural changes being necessary.

Nachfolgend wird anhand der in der Zeichnung veranschaulichten Ausführungsbeispiele die Erfindung näher beschrieben. Es zeigen:Further advantageous details of the invention are specified in the subclaims. The invention is described in more detail below with reference to the exemplary embodiments illustrated in the drawing. Show it:

In Fig. 1 ist ein Zentralverschluß für Schuhe, insbesondere für Sport-, Freizeit- oder Rehabilitationsschuhe, von der Seite im Querschnitt - d.h. in einem Schnitt durch die Zentralachse - dargestellt, der ein als flache Gehäuse¬ schale ausgebildetes Gehäuseteil 1 mit einer kreisförmigen Aussparung 2 zur Aufnahme einer Seilscheibe 3 aufweist. Die Seilscheibe 3 ist über ein Getriebe antreibbar, das zwischen der Seilscheibe 3 und einem von außen betätigbaren Drehglied 33 oder von einem anderen Betätigungsglied, beispielsweise einem Hebel oder Hebelsystem, vorgesehen ist.In Fig. 1 is a central closure for shoes, especially for sports, leisure or rehabilitation shoes, from the side in cross section - i.e. in a section through the central axis - which has a housing part 1 designed as a flat housing shell with a circular recess 2 for receiving a rope pulley 3. The rope sheave 3 can be driven via a gear mechanism which is provided between the rope sheave 3 and an externally actuatable rotary member 33 or another actuating member, for example a lever or lever system.
Vorzugsweise kommt ein Getriebe zur Anwendung, wie es in dem älteren Patent DE 42 40 916 Cl vom 4.12.1992 beschrieben ist. Die vorliegende erfindungsgemäße Ausführung ist jedoch nicht auf die Kombination mit dieser Getriebeart beschränkt. Zwischen der Seilscheibe 3 und dem Boden 8 des Gehäuse¬ teils 1 ist ein flacher, scheibenförmiger Hohlraum 40 vorge¬ sehen, in den ein als Zahnritzel 41 mit einer Zahnung 41a ausgebildeter Achsansatz der Seilscheibe 3 hineinragt. Die senkrechte Gehäuseinnenwand des Hohlraums 40 ist mit einer kreisrunden Zahnung 42a in Form eines Innenzahnkranzes 42 versehen. In dem zwischen dem Zahnritzel 41 und der Zahnung 42a des Innenzahnkranzes 42 gebildeten Zwischenraum 49 ist ein mit diesen beiden Getriebeteilen 41, 42 kämmendes Zahnrad 43 mit gleichem Modul wie die beiden anderen Getriebeteile 41, 42 angeordnet und durch die Unterseite 44 der Seilscheibe 3 und die innere Bodenfläche 45 des Bodens 8 freilaufend geführt.A transmission is preferably used, as described in the older patent DE 42 40 916 Cl of December 4, 1992. However, the present embodiment according to the invention is not limited to the combination with this type of transmission. Between the sheave 3 and the bottom 8 of the housing part 1, a flat, disc-shaped cavity 40 is provided, into which an axial extension of the sheave 3 formed as a pinion 41 with teeth 41a projects. The vertical housing inner wall of the cavity 40 is provided with a circular toothing 42a in the form of an internal ring gear 42. In the space 49 formed between the pinion 41 and the toothing 42a of the internal ring gear 42, a gear 43 meshing with these two gear parts 41, 42 is arranged with the same module as the other two gear parts 41, 42 and through the underside 44 of the pulley 3 and the inner bottom surface 45 of the bottom 8 guided freely.
Im Hohlraum 40 ist an einer Stelle ein Anschlag 46, beispielsweise ein am Boden 8 angeformter oder in diesen eingesetzter Zapfen vorgesehen, der in die Kreisbahn, auf der das Zahnrad 43 umläuft, hineinragt und so dessen Be¬ wegungsspielraum nach beiden Drehrichtungen hin begrenzt.Provided in the cavity 40 at one point is a stop 46, for example a pin molded onto or inserted into the base 8, which protrudes into the circular path on which the toothed wheel 43 rotates and thus limits its range of motion in both directions of rotation.
Durch diese Maßnahmen ist die Umdrehungszahl der Seil¬ scheibe 3 entsprechend dem Übersetzungsverhältnis des Getriebes aus Zahnritzel 41, Innenzahnkranz 42 bzw. Zahnung 42a und Zahnrad 43 sowie der Anordnung des Anschlags 46 vorgegeben bzw. errechenbar und damit an die gegebenen An¬ forderungen anpaßbar. Durch die Wahl der Teilkreisdurch¬ messer des Zahnritzels 41 und des Zahnrades 43 und/oder entsprechend der Länge des durch den Anschlag 46 für das Zahnrad 43 gesperrten Kreisbahnweges ist es möglich, die Umdrehungszahl der Seilscheibe 3 festzulegen bzw. spezifischen Anforderungen anzupassen.By means of these measures, the number of revolutions of the cable pulley 3 is predetermined or calculable in accordance with the transmission ratio of the gear comprising pinion 41, internal ring gear 42 or toothing 42a and gear 43 and the arrangement of the stop 46 and can therefore be adapted to the given requirements. By selecting the pitch circle diameter of the pinion 41 and the gear 43 and / or according to the length of the circular path blocked by the stop 46 for the gear 43, it is possible to determine the number of revolutions of the sheave 3 or to adapt it to specific requirements.
Der Teilkreisdurchmesser des Zahnritzels 41 bzw. des Zahnrades 43 entspricht jeweils dem Produkt aus dem Modul (gemessen beispielsweise in "mm") und der Zähnezahl.The pitch circle diameter of the pinion 41 or the gear 43 corresponds to the product of the module (measured for example in "mm") and the number of teeth.
Das erfindungsgemäße, zur Begrenzung der Umdrehungszahl der Seilscheibe 3 vorgesehene Getriebe ist prinzipiell ein Planetentrieb, wobei das Zahnritzel 41 das Sonnenrad und das freilaufende Zahnrad 43 das Planetenrad bildet.The transmission according to the invention, intended to limit the number of revolutions of the rope pulley 3, is in principle a planetary gear, the pinion gear 41 forming the sun gear and the freewheel gear 43 forming the planet gear.
Die Wirkungsweise der erfindungsgemäßen .Anordnung zur Begrenzung der Umdrehungszahl der Seilscheibe 3 ist folgende:The mode of operation of the arrangement according to the invention for limiting the number of revolutions of the sheave 3 is as follows:
Wird das Zahnritzel 41 aus der in Fig. 2 dargestellten Einstellung entgegen dem Uhrzeigersinn gedreht, so wird das Zahnrad 43 im Uhrzeigersinn angetrieben und es bewegt sich entgegen dem Uhrzeigersinn auf einer Kreisbahn.If the pinion 41 is rotated counterclockwise from the setting shown in FIG. 2, the gear 43 is driven clockwise and it moves in a counterclockwise direction on a circular path.
Die Fig. 3 zeigt die Stellung des Getriebes nach einer Drehung des Zahnritzels 41 um 180°. Entsprechend der dargestellten Zähnezahl von 14 für das Zahnritzel 41 und von 56 Zähnen der Zahnung 42a des Innenzahnkranzes 42 und dem daraus resultierenden Übersetzunsverhältnis:Fig. 3 shows the position of the transmission after rotation of the pinion 41 by 180 °. Corresponding to the number of teeth shown of 14 for the pinion 41 and of 56 teeth of the teeth 42a of the internal ring gear 42 and the resulting transmission ratio:
Zähnezahl AußenradNumber of teeth outer wheel
Ü = 1 +Ü = 1 +
Zähnezahl InnenradNumber of teeth inner wheel
von 5 hat sich hierbei das Zahnrad 43 um 36° weiterbewegt.of 5 the gear 43 has moved further by 36 °.
Beim Weiterdrehen des Zahnritzels 41 kommt nach vier vollen Umdrehungen schließlich das Zahnrad 43 an den Anschlag 46, wie in Fig. 4 dargestellt. Dabei hat sich das Zahnrad 43 um 288° auf seiner Kreisbahn weiterbewegt. Wie ohne weiteres erkennbar, kann der Bewegungsbereich des Zahnrads 43 in einfacher Weise dadurch noch weiter beschränkt werden, daß. wie beispielsweise in den Fig. 2 bis 4 gestrichelt einge¬ zeichnet, ein zweiter Anschlag 46' vorgesehen ist. Hierzu können im Boden 8 des Gehäuseteils 1 mehrere Stecköffnungen in verschiedenen Winkelabständen voneinander vorhanden sein, in die je nach gewünschter Begrenzung der Umdrehungszahl der Seilscheibe 3 weitere Zapfen 46' eingesteckt werden können. Anstelle von zwei Anschlägen 46, 46' kann auch nur ein Anschlag vorgesehen sein, der sich über einen gewünschten, zu sperrenden Winkelbereich erstreckt oder es sind mehrere solcher Anschläge angebracht. Auf diese Weise kann durch die Wahl der Anschläge 46, 46' usw. auch ohne Änderung der Be¬ messungen des Getriebes aus Zahnritzel 41, Innenzahnkranz 42 und Zahnrad 43 ein großer Variationsbereich der möglichen Umdrehungszahlen der Seilscheibe 3 eingestellt werden.When the pinion 41 continues to rotate, the gear 43 finally comes to the stop 46 after four full rotations, as shown in FIG. 4. The gear 43 has moved 288 ° on its circular path. As can be readily recognized, the range of motion of the gear 43 can be further limited in a simple manner by the fact that. as shown in dashed lines in FIGS. 2 to 4, a second stop 46 'is provided. For this purpose, several plug openings can be present in the bottom 8 of the housing part 1 at different angular distances from one another, into which, depending on the desired limitation of the number of revolutions of the sheave 3, further pins 46 'can be inserted. Instead of two stops 46, 46 ', it is also possible to provide only one stop which extends over a desired angular range to be blocked, or a plurality of such stops are attached. In this way, by selecting the stops 46, 46 ', etc., a large range of possible rotation speeds of the pulley 3 can be set even without changing the dimensions of the gear comprising the pinion 41, the internal ring gear 42 and the gear 43.
Bei dem in den Fig. 5 bis 7 dargestellten Ausführungsbei¬ spiel eines Begrenzungsgetriebes für die Umdrehungszahl der Seilscheibe 3 ist das Zahnritzel 41 feststehend angeordnet, indem es beispielsweise ein Teil des Gehäuseteils 1 selbst oder an diesem unverdrehbar befestigt ist. Der Antrieb des Zahnrads 43 erfolgt über die an der Seilscheibe 3 vorge¬ sehene Zahnung 42b in Form eines Innenzahnkranzes 42. Jedoch ist hierbei die Zahnung 42b nicht vollständig durchgebildet und der nicht gezahnte, einen nach innen ragenden Steg 47 aufweisende Abschnitt 48 (Fig. 6) bildet den Anschlag 46 zur Begrenzung des Weges des Zahnrades 43.In the exemplary embodiment of a limiting gear for the number of revolutions of the rope pulley 3 shown in FIGS. 5 to 7, the pinion 41 is arranged in a fixed manner, for example by fastening part of the housing part 1 itself or non-rotatably on it. The gear 43 is driven via the toothing 42b provided on the rope pulley 3 in the form of an internal ring gear 42. However, the toothing 42b is not completely formed here and the non-toothed section 48 having an inwardly projecting web 47 (FIG. 6 ) forms the stop 46 to limit the path of the gear 43.
Wird bei dieser Ausführung die Seilscheibe 3 über das Drehglied 33 gemäß Fig. 5 entgegen dem Uhrzeigersinn gedreht, so wird auch das Zahnrad 43 entgegen dem Uhrzeiger¬ sinn gedreht und zugleich auch im gleichen Richtungssinn auf seiner Kreisbahn um das Zahnritzel 41 bewegt. Nach einer halben Umdrehung der Seilscheibe 3 ist die in Fig. 6 gezeigte Einstellung erreicht. Bei dem hier gewählten ÜbersetzungsverhältnisIn this embodiment, if the rope pulley 3 is rotated counterclockwise via the rotary member 33 according to FIG. 5, the gear 43 is also rotated counterclockwise and at the same time is also moved in the same direction on the circular path around the pinion 41. After half a turn of the sheave 3, the setting shown in FIG. 6 is reached. With the gear ratio chosen here
Zähnezahl AußenradNumber of teeth outer wheel

von 4 durch 42 Zähne der Zahnung 42b und 14 Zähne des Zahn¬ ritzels 41 ist hierbei der relative Weg des Zahnritzels 41 zur Seilscheibe 3 genau 45°, d.h. eine Umdrehung der Seil¬ scheibe 3 entspricht der Weiterbewegung um den relativen Weg von 90°.of 4 by 42 teeth of the teeth 42b and 14 teeth of the pinion 41, the relative path of the pinion 41 to the pulley 3 is exactly 45 °, i.e. one revolution of the sheave 3 corresponds to the further movement by the relative path of 90 °.
Nach drei vollen Umdrehungen der Seilscheibe 3 ist die in Fig. 7 dargestellte Endstellung erreicht. Die Größe des Abschnitts 48 entspricht hier der Sperrung einer ganzen Umdrehung der Seilscheibe 3. Der relative Weg von Zahn¬ ritzel 41 zur Seilscheibe 3 erreicht hier 270°.After three full rotations of the sheave 3, the end position shown in FIG. 7 is reached. The size of the section 48 corresponds here to the blocking of a complete revolution of the rope sheave 3. The relative path from the toothed pinion 41 to the rope sheave 3 reaches 270 ° here.
Mit der Erfindung kann also ohne Vergrößerung des Bauvolumens des Zentralverschlusses die gewünschte Um¬ drehungszahl der Seilscheibe 3 auf beispielsweise zwei bis zehn Umdrehungen eingestellt werden, was durch das Einsetzen bzw. Vorsehen von Anschlägen 46, 46' oder dgl. und/oder durch Änderung der Durchmesser von Zahnritzel 41 und Zahnung 42a bzw. 42b des Innenzahnkranzes 42 bei entsprechender Anpassung des Zahnrades 43 ermöglicht wird.With the invention, the desired number of revolutions of the rope sheave 3 can thus be set to, for example, two to ten revolutions without increasing the overall volume of the central lock, which is achieved by inserting or providing stops 46, 46 'or the like and / or by changing the Diameter of pinion 41 and toothing 42a or 42b of the inner ring gear 42 is made possible with a corresponding adjustment of the gear 43.
Die beiden Ausführungsvarianten der Erfindung, wie in den Fig. 2 bis 4, einerseits und in den Fig. 5 bis 7 anderer¬ seits dargestellt, sind dadurch gekennzeichnet, daß jeweils wenigstens eine Zahnnut der Zahnung 42a des unbeweglichen Teils- Gehäuseteils 1 - bzw. der Zahnung 42b des beweglichen Teils - Seilscheibe 3 - geschlossen ist oder nicht oder jedenfalls nicht vollständig als Zahnnut ausgebildet ist. The two embodiment variants of the invention, as shown in FIGS. 2 to 4 on the one hand and in FIGS. 5 to 7 on the other hand, are characterized in that at least one tooth groove of the toothing 42a of the immovable Part housing part 1 - or the toothing 42b of the movable part - rope pulley 3 - is closed or not, or in any case not completely, in the form of a tooth groove.
