Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Schleifen von Laufflächenkanten eines Wintersportgerätes mit einer Topfscheibe, die mit einer Antriebseinrichtung antriebsverbunden und mit ihrer Stirnseite mittels einer Stelleinrichtung in Zustellrichtung verlagerbar ist und mit einer Führung für die entlang der Kantenflächen des Wintersportgerätes verlagerbare Topfscheibe, welche Topfscheibe mittels der Stelleinrichtung quer zur Führungsebene verlagerbar ist, wobei die Topfscheibe samt Antriebseinrichtung in einem die Führung bildenden Gehäuse in Richtung der Drehachse der Topfscheibe (5) verlagerbar istThe invention relates to a device for grinding tread edges of a winter sports equipment with a cup wheel which is drivingly connected to a drive means and with its front side by means of an adjusting device in the delivery direction and with a guide for the movable along the edge surfaces of the winter sports device cup wheel, which cup disc means the adjusting device is displaceable transversely to the guide plane, wherein the cup wheel together with drive means in a housing forming the guide in the direction of the axis of rotation of the cup wheel (5) is displaceable

Skier besitzen als längsseitigen Abschluss ihrer Lauffläche zwei in der Regel aus Stahl bestehende metallische Leisten, die als "Stahlkanten" bezeichnet werden. Diese Stahlkanten sorgen für guten "Griff" bei eisigem - oder Kunstschneeuntergrund. Im Laufe der Zeit werden diese Kanten jedoch stumpf, da das Metall verformt oder abgeschliffen wird. Es bedarf daher eines regelmäßigen Nachschleifens dieser Stahlkanten, um die guten Fahreigenschaften zu erhalten. Zum Nachschleifen im Selbstschleifverfahren wurden bisher von den Skifahrern beispielsweise mit Handfeilen ausgebildete Skikanten-Schleifgeräte verwendet.Skis have as a longitudinal end of their tread two usually made of steel metallic strips, which are referred to as "steel edges". These steel edges provide good grip on icy or artificial snow surfaces. Over time, however, these edges become dull as the metal is deformed or abraded. It therefore requires a regular regrinding of these steel edges in order to maintain the good handling characteristics. For regrinding in the self-grinding process previously trained by the skiers, for example, with hand files Skikanten-Schleifgeräte were used.

Aus der AT 2 92 495B ist bereits ein Schleifgerät zum Schärfen von Schikanten bekannt, dessen Trag- und Führungskörper aus zwei Teilen besteht, die mittels einer Schwalbenschwanzführung beweglich zueinander angeordnet sind. Von diesen beiden Teilen ist der Führungskörper (Grundführungsplatte) auf der aufliegenden Fläche am Wintersportgerät mit Rollen ausgestattet, die teilweise als Laufrollen und teilweise als Kantenführung dienen, während an dem Tragkörper (Fußteil des Motortragekörper), zu dem vorerwähnten Teil relativ beweglichen Teil die dem Antrieb der Schleifscheibe dienende Motoreinheit starr befestigt und der Schleifscheibe koaxial zur Motorantriebswelle angeordnet ist. Dieses Gerät hat die Nachteile, dass es durch die Schwalbenschwanzführung sehr aufwändig in der Herstellung ist und dadurch die Fertigungskosten hoch sind, und es obendrein ein sehr komplexes Gerät ist.
Aus der DE 3048253A1 ist bekannt, dass die Topfscheibe (Schleifscheibe) die optimalen Voraussetzungen für das Schleifen von Kantenflächen bietet, wobei dieses Gerät von der Handhabe nicht optimal ausgeführt ist, da die Verstellung der Arbeitstiefe der Topfscheibe während der Bearbeitung nur umständlich zu bedienen ist. Durch das Winkelgetriebe oder das Schneckengetriebe können wiederum Fehlerquellen auftreten. Da bei dieser Vorrichtung alle beweglichen Teile nicht ohne Axialspiel der Drehachse der Topfscheibe bearbeitet werden können, ist es nicht möglich mit einer exakten Arbeitstiefeneinstellung der Topfscheibe über die Stahlkanten zu gleiten. Die Gleitsteine (Führung für die Laufflächenkante) sind mit einem relativ kleinen Radius ausgeführt, was ein Hindernis bei Vertiefungen der Stahlkanten darstellt. Wenn ein Gleitstein mit einem kleinen Radius in eine Vertiefung der Stahlkante eintaucht, dann schleift die Schleifscheibe um den Abstand vom Gleitstein zur Schleifscheibe ebenso eine Vertiefung in die Stahlkante, so werden die Vertiefungen in der Stahlkante nach jeden Schleifvorgang verdoppelt. Es ist auch keine Stahlkantenwinkeleinstellvorrichtung vorhanden, daher kann nur der Stahlkantenwinkel geschliffen werden, der durch die Konstruktion des Kantenschleifgerätes vorgegeben ist. Da bei den verschiedenen Schneeverhältnissen ein verschiedener Stahlkantenwinkel erforderlich ist, ist es sehr wichtig, einen verschiedenen Stahlkantenwinkel schleifen zu können.
Aus DE 3026776 A1 ist ein Gerät zum Schärfen von Schikanten bekannt, in der auch die Zustelleinrichtung der Schleifscheibe mit einer integrierten Druckfeder ausgestattet ist. Bei diesem Gerät drückt die Druckfeder die Schleifscheibe in die Richtung der zu schleifenden Stahlkante, dadurch ist immer ein Druck auf der Schleifscheibe der gegen die zu bearbeitende Kantenfläche drückt.
Dadurch kann keine exakte Arbeitstiefe der Schleifscheibe eingestellt werden, bei einem Anhalten mit dem Schleifgerät unter dem Schleifvorgang, schleift sich die Schleifscheibe in die Stahlkante eine Vertiefung hinein.
From AT 2 92 495B a grinder for sharpening Schikanten is already known, the support and guide body consists of two parts, which are arranged movable by means of a dovetail guide to each other. Of these two parts, the guide body (basic guide plate) on the overlying surface on winter sports equipment equipped with rollers, which serve partly as rollers and partly as edge guide, while on the support body (foot part of the motor support body), to the aforementioned part relatively movable part of the drive rigidly attached to the grinding wheel motor unit and the Grinding wheel is arranged coaxially to the motor drive shaft. This device has the disadvantages that it is very laborious to produce due to the dovetail guide, and thus the manufacturing costs are high, and on top of that it is a very complex device.
From DE 3048253A1 it is known that the cup wheel (grinding wheel) provides the optimum conditions for the grinding of edge surfaces, this device is not optimally executed by the handle, since the adjustment of the working depth of the cup wheel during processing is only cumbersome to use. By the angle gear or worm gear error sources can again occur. Since in this device all moving parts can not be processed without axial clearance of the rotary axis of the cup wheel, it is not possible with an exact working depth adjustment of the cup wheel to slide over the steel edges. The sliding blocks (guide for the tread edge) are designed with a relatively small radius, which is an obstacle at recesses of the steel edges. If a sliding block with a small radius dips into a recess in the steel edge, then the grinding wheel also grinds a recess in the steel edge by the distance from the sliding block to the grinding wheel so that the recesses in the steel edge are doubled after each grinding process. Also, there is no steel edge angle adjuster, therefore, only the steel edge angle specified by the design of the edge grinder can be ground. Since different steel edge angles are required for different snow conditions, it is very important to be able to grind a different steel edge angle.
From DE 3026776 A1 a device for sharpening Schikanten is known, in which the feed device of the grinding wheel is equipped with an integrated compression spring. In this device, the compression spring presses the grinding wheel in the direction of the steel edge to be ground, thereby always a pressure on the grinding wheel presses against the edge surface to be machined.
As a result, an exact working depth of the grinding wheel can not be adjusted; when stopping with the grinding device under the grinding process, the grinding wheel grinds a recess into the steel edge.

Aus CH 661 876 A5 ist ein Schleifgerät bekannt, welches die Vorteile einer Topfscheibe aufweist, aber keine spielfreie Zustellung durch einen federbelasteten Gewindetrieb aufweist, und die Arbeitstiefe der Topfscheibe nicht während eines Schleifvorganges nachgestellt werden kann.From CH 661 876 A5 a grinding device is known, which has the advantages of a cup wheel, but has no play-free delivery by a spring-loaded screw, and the working depth of the cup wheel can not be readjusted during a grinding process.

Es ist die Aufgabe der vorliegenden Erfindung ein als Handgerät ausgebildetes Stahlkantenschleifgerät zu schaffen, das eine zentrale, axialspielfreie Arbeitstiefenzustellung der Topfscheibe ermöglicht und breite Führungsbacken aufweist, um über durch Steine verursachte Vertiefungen (Scharten) der Stahlkanten zu gleiten. Das sehr handlich und leicht zu transportieren ist, sich leicht bedienen lässt und das zuletzt ein hervorragendes Schleifergebnis liefert. So liegt ein handliches Gerät vor, das ein Schärfen von Laufkantenflächen einfach ausführen lässt.It is the object of the present invention to provide a trained as a hand-held steel edge grinder, which allows a central, axial play free working depth of the cup wheel and has wide guide jaws to slide over stones caused by pits (nicks) of the steel edges. This is very handy and easy to transport, easy to operate and the last one delivers an excellent sanding result. This is a handy device that makes it easy to sharpen running surfaces.

Die Erfindung löst die Aufgabe dadurch, dass die Topfscheibe und die Antriebseinrichtung mittels eines federbelasteten Gewindetriebes als Stelleinrichtung gegen die Kraft einer Feder in Zustellrichtung der Topfscheibe und in Richtung der Drehachse der Topfscheibe verlagerbar sind. Das ergibt eine exakte Arbeitstiefenzustellung, der Topfscheibe und durch die breite Führung (Gleitflächen) einen exakten Schleifverlauf.The invention solves the problem in that the cup wheel and the drive means are displaceable by means of a spring-loaded screw drive as an adjusting device against the force of a spring in the feed direction of the cup wheel and in the direction of the axis of rotation of the cup wheel. This results in an exact working depth, the cup wheel and through the wide guide (sliding surfaces) a precise grinding process.

Zu vorteilhafter Weise ist die Stelleinrichtung aus einer im Gehäuse drehfest gelagerten aber in Richtung der Drehachse der Topfscheibe verlagerbaren Motorführungshülse mit einem Gewinde und einer im Gehäuse drehbar gelagerten, mit dem Gewinde zusammenwirkende Rändelmutter besteht. Dadurch kann kein Axialspiel der Topfscheibe auftreten.Advantageously, the adjusting device consists of a rotatably mounted in the housing but displaceable in the direction of the axis of rotation of the cup wheel motor guide sleeve with a thread and a rotatably mounted in the housing, cooperating with the thread knurled nut. As a result, no axial play of the cup wheel occur.

Weiters ist vorzugsweise vorgesehen, dass der Anstellwinkel der Topfscheibe an die zu schleifende Kantenfläche um eine zur Vorschubachse parallele Achse mittels einer Winkeleinstelleinrichtung einstellbar ist, die einen einerseits die Lauffläche des Wintersportgerätes stützenden und andererseits am Gehäuse befestigten Verstellkörper umfasst.Furthermore, it is preferably provided that the angle of attack of the cup wheel is adjustable to the edge surface to be ground about an axis parallel to the feed axis by means of a Winkeleinstelleinrichtung comprising on the one hand the running surface of the winter sports equipment supporting and on the other hand attached to the housing adjusting body.

Die Erfindung löst die Aufgabe weiters nach einer anderen vorteilhaften Ausführungsvariante dadurch, dass ein am Gehäuse lösbar befestigter, an die Antriebseinrichtung anschließbarer Akkumulator vorgesehen ist. Damit ist eine Mobilität der Vorrichtung gewährleistet.The invention further solves the object according to another advantageous embodiment variant in that a rechargeable battery fastened to the housing and connectable to the drive device is provided. This ensures mobility of the device.

Zur Lösung der Aufgabe ist erforderlich:

  1. 1. Die Arbeitstiefenzustellung der Topfscheibe (Stelleinrichtung), die zentral am Gerät platziert ist.
  2. 2. Die Federkraft der Feder, die vom Gehäuse in Achsrichtung der Topfscheibe gegen die Motorführungshülse drückt, wird zur Axialspielvermeidung der Stelleinrichtung und zur Schwingungsdämpfung der Antriebseinrichtung verwendet.
  3. 3. Die Winkeleinstelleinrichtung, die einen variablen Laufflächenkantenwinkel ausführen lässt
  4. 4. Eine breite Führung der Laufflächenkante, die über Vertiefungen der Laufflächenkanten (z. B. durch Steine verursacht) gleitet.
To solve the task is required:
  1. 1. The working depth of the cup wheel (adjusting device), which is placed centrally on the device.
  2. 2. The spring force of the spring, which presses from the housing in the axial direction of the cup wheel against the motor guide sleeve is used to Axialspielvermeidung the actuator and the vibration damping of the drive device.
  3. 3. The angle adjuster that makes a variable tread edge angle
  4. 4. A wide guide of the tread edge that slides over recesses of the tread edges (eg caused by stones).

Auf diese Weise konnten der Grundaufbau des Kantenschleifgerätes erheblich vereinfacht und damit sowohl der Fertigungsaufwand als auch die Herstellkosten reduziert und auch sichergestellt werden, damit die Topfscheibe, die sich für die Bearbeitung von Kantenflächen besonders eignet, Anwendung findet.In this way, the basic structure of the edge sanding device could be considerably simplified and thus both the production cost and the production costs can be reduced and also ensured, so that the cup wheel, which is particularly suitable for the processing of edge surfaces, applies.

Es zeigt Fig.1 eine zentrale und einfach verstellbare Stelleinrichtung 2,3, die aus einer Motorführungshülse 2 mit Gewinde und einer Rändelmutter 3 besteht, die im Gehäuse 8 gelagert sind. Die durch die Feder 4 auftretende Federkraft, die vom Gehäuse 8 in Richtung der Drehachse der Topfscheibe 5 gegen die Motorführungshülse 2 drückt wird zur Axialspielvermeidung der Topfscheibe 5 und zur Schwingungsdämpfung der Antriebseinrichtung 1 verwendet. Damit sich die Führungshülse 2 im Gehäuse 8 nicht radial verdrehen kann ist im Gehäuse 8 eine Nut, und in der Motorführungshülse 2 eine Kulisse 10 vorhanden.1 shows a central and easily adjustable adjusting device 2, 3, which consists of a threaded motor guide sleeve 2 and a knurled nut 3, which are mounted in the housing 8. The spring force occurring by the spring 4, which presses from the housing 8 in the direction of the axis of rotation of the cup wheel 5 against the motor guide sleeve 2 is used for Axialspielvermeidung the cup wheel 5 and the vibration damping of the drive device 1. Thus, the guide sleeve 2 in the housing 8 can not rotate radially in the housing 8 is a groove, and in the motor guide sleeve 2, a link 10 available.

Durch die Verdrehung der Rändelmutter 3 auf dem Gewinde der Motorführungshülse 2, wird die Drehbewegung der Rändelmutter 3 in die Axialbewegung der Motorführungshülse 2 umgewandelt. Die axiale Verlagerung der Topfscheibe 5 zur zu schärfenden Kantenfläche 12 (Stahlkante) erfolgt über die zu verdrehende Rändelmutter 3 über die Motorführungshülse 2, die mit der Antriebseinrichtung 1 fix verbunden ist, und über den Schleifscheibenadapter 6, der mit der Welle der Antriebseinrichtung 1 verbunden ist, über die Topfscheibe 5, die mittels einer Klemmschraube 7 auf den Schleifscheibenadapter 6 geklemmt ist.
Damit die Topfscheibe 5 lösbar und fixierbar ist, ist im Gehäuse 8 eine Bohrung 15 vorgesehen, wo man mit einem hindurch gesteckten Steckbolzen den Schleifscheibenadapter 6 fixiert, wobei mit einem dafür vorgesehenem Werkzeug die Klemmschraube 7 und damit die Topfscheibe 5 zu lösen oder fixieren ist. Das Wintersportgerät 20 wird mit einer Klemmvorrichtung so geklemmt, dass die zu schleifende Kantenfläche 12 nach oben zeigt und das mit der Hand geführte Kantenschleifgerät wird mit einem leichten Anpressdruck über das Wintersportgerät 20 geschoben. Die Vorschubrichtung 16, die vorwärts oder rückwärts sein kann, ist nicht vorgegeben. Mittels der Führung 11 liegt das Kantenschleifgerät auf den Laufkantenflächen 12,13 an und mittels der Winkeleinstelleinrichtung 9 liegt das Kantenschleifgerät auf der Lauffläche 18 an. Der Anstellwinkel 17 der Topfscheibe 5 an die zu schleifenden Kantenfläche 12 wird mittels der Winkeleinstelleinrichtung 9, ersichtlich durch eine Winkelskala, eingestellt. Wie aus Fig.1 ersichtlich, ist ein Anstellwinkel 17 von ca. 3° eingestellt, das entspricht einem Stahlkantenwinkel 21 von ca. 87°. Desto mehr die Winkeleinstelleinrichtung 9 in Richtung Lauffläche 18 verschoben wird, umso mehr verlagert sich das Kantenschleifgerät (Drehpunkt ist die Laufflächenkante) in Richtung des Wintersportgerätes 18 und dadurch wird der Stahlkantenwinkel 21 spitzer.
In den Figuren 1, 2, und 3 ist das Gerät mit einem Akkumulator 19 ersichtlich, die Antriebseinrichtung 1 kann auch mit einer anderen Energiequelle versorgt werden.
Due to the rotation of the knurled nut 3 on the thread of the motor guide sleeve 2, the rotational movement of the knurled nut 3 is converted into the axial movement of the motor guide sleeve 2. The axial displacement of the cup wheel 5 to be sharpened edge surface 12 (steel edge) via the knurled nut 3 via the motor guide sleeve 2, which is fixedly connected to the drive device 1, and via the grinding wheel adapter 6, which is connected to the shaft of the drive device 1 , via the cup wheel 5, which is clamped by means of a clamping screw 7 on the grinding wheel adapter 6.
Thus, the cup wheel 5 is detachable and fixable, a bore 15 is provided in the housing 8, where fixed with a plug pin inserted through the grinding wheel adapter 6, with a designated tool, the clamping screw 7 and thus the cup wheel 5 to solve or fix. The winter sports device 20 is clamped with a clamping device so that the edge surface 12 to be ground points upward and the hand-guided edge sanding device is pushed over the winter sports device 20 with a slight contact pressure. The feed direction 16, which may be forward or backward, is not predetermined. By means of the guide 11, the edge sanding device rests on the running edge surfaces 12, 13, and by means of the angle adjustment device 9, the edge sanding device rests on the running surface 18. The angle of attack 17 of the cup wheel 5 to the edge surface 12 to be ground is adjusted by means of the angle adjustment 9, indicated by an angle scale. As can be seen from Fig.1, an angle 17 is set by about 3 °, which corresponds to a steel edge angle 21 of about 87 °. The more the Winkeleinstelleinrichtung 9 is displaced in the direction of tread 18, the more displaces the edge sanding (fulcrum is the tread edge) in the direction of winter sports equipment 18 and thereby the steel edge angle 21 is sharpener.
In Figures 1, 2, and 3, the device with an accumulator 19 can be seen, the drive device 1 can also be supplied with a different energy source.

Vor dem Aufsetzen des Kantenschleifgerätes auf das Wintersportgerät 20, wird der Anstellwinkel 17 der Topfscheibe 5 mittels der Winkeleinstelleinrichtung 9 eingestellt und darauf geachtet, dass die Topfscheibe 5 nicht über die Führung 11 für die zu schleifende Laufflächenkanten vorragt, damit die Topfscheibe 5 beim Einschalten des Kantenschleifgerätes nicht unkontrolliert auf der Laufkantenfläche 12 herumschleift. Wie aus FIG. 1 ersichtlich, wird das Kantenschleifgerät mit den Führungsbacken 11 und der Winkeleinstelleinrichtung 9 gegen das Wintersportgerät 20 gedrückt. Nach dem Einschalten des Kantenschleifgerätes muss man mit der freien Hand an der Rändelmutter 3 so lange gegen den Uhrzeigersinn drehen, bis die gewünschte Arbeitstiefe der Topfscheibe 5 erreicht ist. Dann wird das Kantenschleifgerät händisch in Vorschubrichtung 16, welche vorwärts oder rückwärts sein kann, geschoben. Das Kantenschleifgerät befindet sich in der Arbeitsstellung im stabilen Gleichgewicht. So lässt sich bei einer derart ergonomischen Handhabung des Kantenschleifgerätes durch keinen besonderen Kraftaufwand, sondern nur durch einen leichten Anpressdruck und leichten Vorschub verschieben. Je langsamer die Vorschubsgeschwindigkeit ist, desto feiner wird die Oberfläche der zu schleifenden Laufkantenfläche 12. Zum Wechseln der Topfscheibe 5 ist im Gehäuse 8 sowie in der Motorführungshülse 2 eine Bohrung 15 vorgesehen, worin man mitels einem Ansteckbolzen der durch die Bohrung 15 in den Schleifscheibenadapter 6, in dem ebenfalls eine Bohrung ist, gesteckt wird, den Schleifscheibenadapter 6 auf Verdrehung sichert, und dann die Klemmschraube 7 mit einem dafür vorgesehenem Werkzeug lösen oder fixieren kann.Before placing the edge sanding device on the winter sports equipment 20, the pitch 17 of the cup wheel 5 is adjusted by means of the Winkeleinstelleinrichtung 9 and ensured that the cup wheel 5 does not project beyond the guide 11 for the running surface edges to be ground so that the cup wheel 5 when switching the edge sanding not uncontrollably on the running edge surface 12 herumschleift. As shown in FIG. 1, the edge sanding device with the Guide jaws 11 and the Winkeleinstelleinrichtung 9 pressed against the winter sports equipment 20. After switching on the edge sanding unit, you must turn the knurled nut 3 with your free hand counterclockwise until the desired working depth of the cup wheel 5 is reached. Then, the edge grinder is pushed manually in the feed direction 16, which may be forward or backward. The edge sanding unit is in stable working position in the working position. Thus, with such an ergonomic handling of the edge sanding device by no special effort, but only by a slight contact pressure and slight feed move. The slower the feed rate, the finer is the surface of the running edge surface 12 to be ground. For changing the cup wheel 5, a bore 15 is provided in the housing 8 and in the motor guide sleeve 2, wherein mitels a Ansteckbolzen through the hole 15 in the grinding wheel adapter. 6 , in which also is a hole is plugged, the grinding wheel adapter 6 secures to rotation, and then solve the clamping screw 7 with a dedicated tool or can fix.

Es zeigt Fig.5 eine Überarbeitung des Kantenschleifgerätes mit einer Rändelmutter 3, die mit einer 30° Fase versehen ist, durch diese Fase zentriert sich die Rändelmutter radial im Gehäuse 8. Die Mündungshülse 23 wird aus Spritzgusstechnischen Gründen dem Gehäuse 8 beigelegt. Im Innendurchmesser hat die Mündungshülse drei Auflagepunkte wodurch die Motorführungshülse 2 radial gelagert ist, und eine Verklemmung der Motorführungshülse 2 mit der Mündungshülse 23 durch Schleifstaub (Schmutz) zu vermeidet. Durch den Ventilator 22 der mit der Topfscheibe 5 auf den Schleifscheibenadapter 6 geklemmt ist, wird Luft über die Topfscheibe 5 geblasen und bläst den Schleifstaub weg.5 shows a revision of the edge sanding device with a knurled nut 3, which is provided with a 30 ° chamfer, through this chamfer, the knurled nut is centered radially in the housing 8. The mouth sleeve 23 is added to the housing 8 for injection-technical reasons. In the inner diameter of the mouth sleeve has three support points whereby the motor guide sleeve 2 is radially mounted, and to avoid jamming of the motor guide sleeve 2 with the mouth sleeve 23 by grinding dust (dirt). By the fan 22 is clamped with the cup wheel 5 on the grinding wheel adapter 6, air is blown over the cup wheel 5 and blows off the grinding dust.

Damit das Gehäuse 8 im Bereich der Führung nicht durch die (scharfen) Laufflächenkanten 14 beschädigt wird, werden als Verbesserungsmaßnahme, wie in Fig.6 ersichtlich, auswechselbare Führungsbacken 24, eingesetzt.So that the housing 8 is not damaged by the (sharp) running surface edges 14 in the region of the guide, interchangeable guide jaws 24 are used as an improvement measure, as can be seen in FIG.
