PCT No. PCT/DE93/01140 Sec. 371 Date Jun. 5, 1995 Sec. 102(e) Date Jun. 5, 1995 PCT Filed Nov. 28, 1993 PCT Pub. No. WO94/13165 PCT Pub. Date Jun. 23, 1994A shoe closure, consisting of a rope pulley mounted rotatably in a bearing element to wind up at least one ropelike tightening element to close the shoe, a rotating element to actuate the rope pulley and a reducing gear between rotating element and rope pulley in the form of an eccentric drive, is to be improved so that no nonuniform tightening or pulling movements of the tightening element occur. This is achieved in that rope pulley (3) is designed as an independent unit mounted rotatably concentrically to central axis (9). Eccentric knob (10) is mounted movably parallel to rope pulley (3) and is movable, by eccentric driving pin (12), in a plane parallel to rope pulley (3). Eccentric knob (10) has one or more sector or sectors (16) on a circle (14) concentric to its axis of rotation (13), sector or sectors whose center or centers (15) lies or lie on concentric circle (14) and whose double radius (rK) is at least approximately equal to the sum of diameter (D) of a coupling pin (17) attached to rope pulley (3) and diameter (DK) of circular path (18) of eccentric driving pin (12) (FIG. 1 ).

Description

Die vorliegende Erfindung bezieht sich auf einen Schuhverschluß gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a shoe closure according to the preamble of claim 1.

Ein derartiger Schuhverschluß ist aus der DE-PS 29 00 077 bekannt.Such a shoe closure is known from DE-PS 29 00 077.

Dort ist als Untersetzungsgetriebe ein selbstsperrendes Exzentergetriebe vorgesehen. Dabei ist die Seilscheibe direkt am Exzentertriebrad angeordnet und macht beim Spannen und Entspannen des Spannelements die Exzenterbewegung des Exzentertriebrades mit. Hierdurch kommt es zu ungleichförmigen Spann- bzw. Zugbewegungen.There a self-locking eccentric gear is provided as a reduction gear. The rope pulley is arranged directly on the eccentric drive wheel and takes part in the eccentric movement of the eccentric drive wheel when tensioning and releasing the tensioning element. This leads to non-uniform tensioning or pulling movements.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, den bekannten Schuhverschluß so zu verbessern, daß keine ungleichförmigen Spann- bzw. Zugbewegungen des Spannelements bzw. der Spannelemente mehr auftreten.The object of the present invention is to improve the known shoe closure in such a way that nonuniform tensioning or pulling movements of the tensioning element or tensioning elements no longer occur.

Gelöst wird diese Aufgabe durch die im Anspruch 1 angegebenen Merkmale.This object is achieved by the features specified in claim 1.

Die vorliegende Erfindung zeichnet sich insbesondere dadurch aus, daß durch die gesonderte Anordnung der Seilscheibe und durch den Antrieb derselben über den bzw. die Kreisausschnitt(e) der Exzentertriebscheibe eine völlig gleichförmige Drehbewegung entsprechend der Drehung des Drehgliedes erzielt wird. Die gewünschte Untersetzung ergibt sich aus der gewählten Zähnezahl des Zahntriebes. Dadurch ist eine sehr feinstufige Einstellung der Schließkraft dieses erfindungsgemäßen Schuhverschlusses möglich.The present invention is characterized in particular in that a completely uniform rotary movement corresponding to the rotation of the rotary member is achieved by the separate arrangement of the cable pulley and by the drive thereof via the circular section (s) of the eccentric drive pulley. The desired reduction results from the selected number of teeth of the pinion. This enables a very fine adjustment of the closing force of this shoe fastener according to the invention.

Besonders vorteilhaft ist, daß der Exzentertrieb derart ausgelegt werden kann, daß er - im Gegensatz zu der vorbekannten Lösung - in beiden Richtungen selbstsperrend ist.It is particularly advantageous that the eccentric drive can be designed such that - in contrast to the previously known solution - it is self-locking in both directions.

Günstig ist auch, daß zwischen einem der drehbaren Teile und einem festen Gehäuseteil oder einem am Gehäuseteil befestigten oder befestigbaren Teil Rastsprungmittel vorgesehen sind, die in jeder eingestellten Drehstellung sperrend verrasten, deren Sperrwirkung jedoch zur Änderung der Drehstellung durch ein am Drehglied angreifendes Drehmoment überwindbar ist.It is also favorable that locking jump means are provided between one of the rotatable parts and a fixed housing part or a part fastened or fastened to the housing part, which lock in any set rotational position, but the locking effect of which can be overcome by a torque acting on the rotating element to change the rotational position.

Der erfindungsgemäße Schuhverschluß besitzt gemäß den Fig. 1 und 2 ein Gehäuseteil 1, das eine kreisförmige Aussparung 2 zur Aufnahme einer Seilscheibe 3 und des oder der seilartigen Spannelements(e) 3a aufweist. Die Einführung des oder der seilförmigen Spannelements(e) 3a in die Seilscheibe 3 erfolgt über an sich bekannte Zuführungen 3b in der Seilscheibe 3. Die Seilscheibe 3 besitzt eine zentrische Bohrung 4, durch die ein Lagerzapfen 5 einer Achseinheit 6 hindurchgreift und in einer Lagerbohrung 7 des Bodens 8 des Gehäuseteils 1 endet. Die Achse des Lagerzapfens 5 bildet zugleich die Zentralachse 9 des Schuhverschlusses.1 and 2, the shoe closure according to the invention has a housing part 1 which has a circular recess 2 for receiving a rope sheave 3 and the rope-like tensioning element (s) 3a. The rope-shaped tensioning element (s) 3a is introduced into the rope sheave 3 via known feeds 3b in the rope sheave 3. The rope sheave 3 has a central bore 4 through which a bearing pin 5 of an axle unit 6 extends and into a bearing bore 7 of the bottom 8 of the housing part 1 ends. The axis of the journal 5 also forms the central axis 9 of the shoe closure.

Auf der Seilscheibe 3 liegt eine Exzentertriebscheibe 10. Diese besitzt eine zentrale Lagerbohrung 11, mit der sie auf einem exzentrisch zur Zentralachse 9 angeordneten Exzentertriebzapfen 12 der Achseinheit 6 drehbar gelagert ist. Auf einem zur Drehachse 13 des Exzentertriebzapfens 12 konzentrischen Kreis 14 (Fig. 7) liegt jeweils der Mittelpunkt 15 von mehreren, hier als Ausführungsbeispiel sechs, Kreisausschnitten 16, in die je ein Kupplungsbolzen 17 der Seilscheibe 3 eingreift. Die Winkellage der Kreisausschnitte 16 entspricht derjenigen der Kupplungsbolzen 17. Vorzugsweise sind die Kreisausschnitte 16 jeweils um einen gleichen Winkel, beim Ausführungsbeispiel um 60°, gegeneinander versetzt. Ausreichend wäre grundsätzlich auch ein einziger Kreisausschnitt 16, der mit nur einem Kupplungsbolzen 17 in Wirkverbindung steht.An eccentric drive pulley 10 lies on the rope pulley 3. This has a central bearing bore 11, with which it is rotatably mounted on an eccentric drive journal 12 of the axle unit 6 arranged eccentrically to the central axis 9. On a circle 14 (FIG. 7) concentric with the axis of rotation 13 of the eccentric drive pin 12 lies the center point 15 of several, here six as an exemplary embodiment, circular sections 16, in each of which a coupling pin 17 of the rope pulley 3 engages. The angular position of the circular sections 16 corresponds to that of the coupling bolts 17. The circular sections 16 are preferably offset from one another by the same angle, in the exemplary embodiment by 60 °. A single circular section 16, which is in operative connection with only one coupling bolt 17, would in principle also be sufficient.

Durch Drehen der Achseinheit 6 um die Zentralachse 9 beschreibt die Drehachse 13 des Exzentertriebzapfens 12 eine zur Zentralachse 9 konzentrische Kreisbahn 18 (Fig. 11). Die Mittelpunkte 19 der Kupplungsbolzen 17 liegen auf einem zur Zentralachse 9 konzentrischen Mittelpunktskreis 20 (Fig. 11).By rotating the axis unit 6 about the central axis 9, the axis of rotation 13 of the eccentric drive pin 12 describes a circular path 18 which is concentric with the central axis 9 (FIG. 11). The center points 19 of the coupling bolts 17 lie on a Central axis 9 concentric center circle 20 (Fig. 11).

Die Außenkontur der Exzentertriebscheibe 10 bildet eine Zahnung 21, die mit einer als Gegenzahnung 22 ausgebildeten Innenkontur eines einseitig nach unten abstehenden Kragens 23 einer die Exzentertriebscheibe 10 überdeckenden Scheibe 24 abrollen kann. Die Scheibe 24 besitzt eine Zentralbohrung 25, mit der diese auf der Achseinheit 6 zur Zentralachse 9 konzentrisch drehbar gelagert ist. Die Scheibe 24 besitzt außerdem ein oder mehrere Befestigungsmittel 26, mittels dem bzw. derer sie am Gehäuseteil 1 in einer oder mehreren Drehstellungen unverdrehbar befestigt werden kann. Insoweit wird auf die Figuren 5, 6, 10 und 11 verwiesen.The outer contour of the eccentric drive disk 10 forms a toothing 21, which can roll with an inner contour, designed as counter toothing 22, of a collar 23 projecting downward on one side of a disk 24 covering the eccentric drive disk 10. The disc 24 has a central bore 25 with which it is rotatably mounted on the axis unit 6 to the central axis 9 concentrically. The disc 24 also has one or more fastening means 26, by means of which it can be fastened non-rotatably to the housing part 1 in one or more rotational positions. In this regard, reference is made to FIGS. 5, 6, 10 and 11.

Die Scheibe 24 besitzt auf der dem Kragen 23 gegenüberliegenden Seite einen weiteren, nach oben abstehenden Kragen 27. Dieser bildet durch seine Innenkontur einen Rastkranz 28 (siehe Fig. 10), gegen den ein Rastvorsprung 29 einer Rastfeder 30 federnd und rastend anliegt. Die Rastfeder 30 ist ihrerseits mittels Befestigungsaugen 31 an Haltezapfen 32 eines die Scheibe 24 überdeckenden Drehgliedes 33 befestigt. Das Drehglied 33 ist beispielsweise durch eine Schraube 34 mit der Achseinheit 6 verbunden oder besteht mit dieser aus einer baulichen Einheit. Das Drehglied 33 ist noch mit einer vorzugsweise elastischen Abdeckkappe 35 versehen, die bevorzugt als Betätigungsglied des vorliegenden Schuhverschlusses dient.On the side opposite the collar 23, the disk 24 has a further collar 27 which projects upwards. Due to its inner contour, this forms a locking collar 28 (see FIG. 10) against which a locking projection 29 of a locking spring 30 rests in a resilient and locking manner. The detent spring 30 is in turn fastened by means of fastening eyes 31 to retaining pins 32 of a rotary member 33 covering the disk 24. The rotary member 33 is connected to the axle unit 6 by a screw 34, for example, or consists of a structural unit. The rotary member 33 is also provided with a preferably elastic cover cap 35, which preferably serves as an actuator of the present shoe closure.

Um ein spielfreies Untersetzungsgetriebe zu erhalten, kann der Radius rK der Kreisausschnitte 16 gleich oder wenigstens annähernd gleich dem Durchmesser DK der Kreisbahn 18 des Exzentertriebzapfens 12 sein.In order to obtain a backlash-free reduction gear, the radius r K of the circular sections 16 can be the same or at least approximately the same as the diameter D K of the circular path 18 of the eccentric drive pin 12.

Grundsätzlich ist der Durchmesser D der Kupplungsbolzen 17 innerhalb bestimmter Grenzen frei wählbar, was auch für den Durchmesser DK der Kreisbahn 18 des Exzentertriebzapfens 12 gilt.In principle, the diameter D of the coupling bolt 17 can be freely selected within certain limits, which also applies to the diameter D K of the circular path 18 of the eccentric drive pin 12.

Es gilt also jeweils die Formel: 2 x r K = D + D K ,

Figure imgb0001
   zuzüglich einem Mindestspiel von etwa 0, 05 mm bis 0,1 mm.The formula therefore always applies: 2 xr K = D + D K ,
Figure imgb0001
 plus a minimum clearance of approximately 0.05 mm to 0.1 mm.

Dies bedeutet, daß der zweifache Radius rK der Kreisausschnitte 16 etwa gleich der Summe des Durchmessers D der Kupplungsbolzen 17 und des Durchmessers DK der Kreisbahn 18 des Exzentertriebzapfens 12 ist.This means that twice the radius r K of the circular sections 16 is approximately equal to the sum of the diameter D of the coupling bolts 17 and the diameter D K of the circular path 18 of the eccentric drive pin 12.

Die Höhe HZ der Gegenzahnung 22 ist wenigstens annähernd gleich der Dicke DE der Exzentertriebscheibe 10.The height H Z of the counter toothing 22 is at least approximately equal to the thickness D E of the eccentric drive pulley 10.

In Fig. 4 ist die Rastfeder 30 mit nur einem Rastvorsprung 29 dargestellt. Es können aber auch zwei oder mehr, bevorzugt gleichmäßig über diesen Federteil verteilte Rastvorsprünge, vorgesehen sein.4, the detent spring 30 is shown with only one detent projection 29. However, two or more locking projections, preferably evenly distributed over this spring part, can also be provided.

Auch können gegebenenfalls zwei oder mehr seilartige Spannelemente zum Schließen des Schuhes eingesetzt werden.If necessary, two or more rope-like tensioning elements can also be used to close the shoe.

Die in beiden Drehrichtungen selbstsperrende Ausgestaltung des Exzentertriebes 6, 10, 17 ist dadurch gegeben, daß die Vertiefungen 28a des Rastkranzes 28 in bezug auf den Rastvorsprung bzw. auf die Rastvorsprünge 29 unabhängig von der Drehrichtung symmetrisch ausgebildet sind. Das für die Überbrückung der Sperrwirkung erforderliche Drehmoment kann durch die Anzahl und das Profil der Vertiefungen 28a und des bzw. der Rastvorsprünge(s) 29 weitestgehend gesteuert werden.The self-locking configuration of the eccentric drive 6, 10, 17 in both directions of rotation is given by the fact that the recesses 28a of the locking ring 28 are formed symmetrically with respect to the locking projection or to the locking projections 29 regardless of the direction of rotation. The torque required for bridging the blocking action can be largely controlled by the number and the profile of the depressions 28a and of the latching projections (s) 29.

Der Lagerzapfen 5, der Exzentertriebzapfen 12 und der aus Figur 1 ersichtliche Lagerachsansatz 6.1 sind als Achseinheit 6 ausgebildet. Diese Achseinheit 6 ist mit dem Drehglied 33, 35 fest verbunden oder bildet mit diesem eine bauliche Einheit.The bearing journal 5, the eccentric drive journal 12 and the bearing axle extension 6.1 shown in FIG. 1 are designed as an axle unit 6. This axis unit 6 is fixed to the rotary member 33, 35 or forms a structural unit with this.
