Abstract

The manual apparatus has a calliper (11) with a probe edge (11a) which is fixedly connected to a housing part (1b). The calliper (11) is arranged on a probe body (8) which accommodates a ball bearing (9) for a peripheral milling cutter (10). This peripheral milling cutter (10) extends through a recess (11c), having the shape of an arc of a circle, in the calliper (11). To grind the ski edge (13), the calliper (11) is to be placed against the side surface thereof. The precise guidance of the peripheral milling cutter (10) during the movement of the manual apparatus in the longitudinal direction of the ski edge (13) permits exact machining of the edges (13) of the skis, even in non-linear areas. <IMAGE>

Description

Die Erfindung betrifft ein Handgerät nach dem Oberbegriff des unabhängigen Patentanspruchs 1. Ein Handgerät dieser Gattung ist durch die AT-B-270 426 bekannt geworden. Nicht zuletzt aus Gründen der Sicherheit, sollten Skikanten regelmässig nachgeschliffen werden. Zum Nachschleifen sind feilenartige Geräte bekannt, die jedoch eine Geschicklichkeit und einen Kraftaufwand erfordern, der meist nicht vorausgesetzt werden kann. Skis können auch im Sportgeschäft nachgeschliffen werden. Hierzu werden Bandschleifgeräte benutzt, die laufflächenseitig die Skikanten abschleifen. Dies ist vergleichsweise teuer und oft ist ein geeignetes Sportgeschäft nicht erreichbar.The invention relates to a hand-held device according to the preamble of independent claim 1. A hand-held device of this type has become known from AT-B-270 426. Not least for safety reasons, ski edges should be reground regularly. File-like devices are known for regrinding, but they require skill and effort, which usually cannot be assumed. Skis can also be reground in the sports shop. Belt sanders are used for this purpose, which sand the ski edges on the tread side. This is comparatively expensive and often a suitable sports shop cannot be reached.

Ebenfalls bekannt sind Handgeräte, die ein rotierendes Werkzeug, beispielsweise eine Schleifscheibe aufweisen, die von einem Motor angetrieben ist. Da nun Skis an ihren Schmalseiten nicht gerade, sondern insbesondere hinter dem Spitz und am hinteren Ende tailliert sind, besteht bei den bekannten Handgeräten die Schwierigkeit, dass die Skikanten in diesen Bereichen nicht exakt geschliffen werden können, und insbesondere die Bearbeitungstiefe über den ganzen Bereich der Skikanten nicht gleichmässig ist. Ein solches Handgerät ist ausser durch die genannte AT-B-270 426 in ähnlicher Ausführung auch durch die EP-B 0 058 983 und die CH-A 661 876 bekannt geworden. Diese Geräte erfordern zudem Einstellarbeiten, was die Bedienung erschwert.Also known are hand-held devices which have a rotating tool, for example a grinding wheel, which is driven by a motor. Since skis are not straight on their narrow sides, but especially tailored behind the point and at the rear end, the known ones exist Handheld devices the difficulty that the ski edges in these areas can not be ground exactly, and in particular the machining depth is not uniform over the entire area of the ski edges. Such a hand-held device is known not only from AT-B-270 426, but also from EP-B 0 058 983 and CH-A 661 876, in a similar design. These devices also require adjustment work, which makes operation more difficult.

Der Erfindung liegt die Aufgabe zugrunde, ein Handgerät der genannten Gattung zu schaffen, aus keine Einstellarbeiten erfordert und mit dem dennoch Skikanten über ihren ganzen Bereich gleichmässig bearbeitbar sind. Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst.The invention has for its object to provide a handheld device of the type mentioned, requires no adjustment work and with which ski edges can still be machined uniformly over their entire area. The object is achieved by the invention according to claim 1.

Ein wesentlicher Aspekt des erfindungsgemässen Handgerätes liegt darin, dass Führungsflächen sich bis nahe an den Umfang des Werkzeuges erstrecken und dass diese Führungsflächen bei der Bearbeitung der Skikanten ausschliesslich auf der zu bearbeitenden Fläche der Skikanten aufliegen. Das Werkzeug folgt damit präzis jeder Biegung einer Skikante. Auf eine Verstellung der Frästiefe kann dadurch verzichtet werden, was den konstruktiven Aufwand und die Bedienung vereinfacht. Weitere vorteilhafte Merkmale und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

An essential aspect of the hand-held device according to the invention is that guide surfaces extend close to the circumference of the tool and that these guide surfaces rest exclusively on the surface of the ski edges to be machined when machining the ski edges. The tool thus precisely follows every curve of a ski edge. An adjustment of the milling depth can be dispensed with, which simplifies the construction effort and the operation. Further advantageous features and developments result from the dependent claims and the following description. An embodiment of the invention is explained below with reference to the drawings. Show it:

Das Handgerät besitzt ein im Spritzgussverfahren aus einem geeigneten Kunststoff hergestelltes Gehäuse 1, das zwei lösbar miteinander verbundene Schaltenteile 1a und 1b aufweist. Die Teile 1a und 1b bilden einen Innenraum 1c, in den eine Motorwelle 3 mit einem Kegelrad 4 hineinragt. Die Welle 3 ist Teil eines Elektromotors, der über einen hier nicht gezeigten Deckel in das Gehäuse 1 eingesetzt ist. Mit dem Kegelrad 4 kämmt ein grösseres Kegelrad 5, das sich ebenfalls im Zwischenraum 1c befindet und das auf den Schaft eines Umfangfräsers 10 aufgespritzt ist. Der Umfangfräser 10 ist mit zwei Kugellagern 7 und 9 in den Gehäuseteilen 1a und 1b gelagert. Diese Kugellager 7 und 9 sind in Lagerschalen 6 und 8 eingesetzt, die vorzugsweise aus Stahl hergestellt und in die Teile 1a und 1b eingespritzt sind. Nach Entfernen des Gehäuseteils 1a kann das Kegelrad 5 mit dem Umfangfräser 10 aus dem Gehäuse 1 herausgenommen und geschärft oder ausgewechselt werden.The hand-held device has a housing 1 which is injection molded from a suitable plastic and has two switch parts 1a and 1b which are detachably connected to one another. The parts 1a and 1b form an interior 1c, into which a motor shaft 3 with a bevel gear 4 projects. The shaft 3 is part of an electric motor which is inserted into the housing 1 via a cover, not shown here. A larger bevel gear 5 meshes with the bevel gear 4, which is also located in the intermediate space 1c and which is sprayed onto the shaft of a circumferential cutter 10. The circumferential cutter 10 is mounted with two ball bearings 7 and 9 in the housing parts 1a and 1b. These ball bearings 7 and 9 are used in bearing shells 6 and 8, which are preferably made of steel and are injected into parts 1a and 1b. After removing the housing part 1a, the bevel gear 5 with the circumferential cutter 10 can be removed from the housing 1 and sharpened or replaced.

Der Gehäuseteil 1b besitzt zwei im Abstand angeordnete Führungsbahnen 15 und 16, die wie in Fig. 1 gezeigt an die Lauffläche 14a des Skis 14 angelegt werden. Zur Führung des Handgerätes dient ebenfalls ein Taster 11, der wie in Fig. 1 gezeigt während der Bearbeitung einer Skikante 13 an der Aussenseite 13a anliegt. Die Berührungsfläche zwischen dem Taster 11 und der Skikante 13 bildet einen schmalen Streifen und befindet sich in Fig. 2 vorzugsweise unterhalb der gezeigten Position. Der Taster 11 liegt somit vorzugsweise auf der inneren Hälfte der Fläche 13a auf. Der Taster 11 besitzt eine Führungsfläche 11a, die durch eine teilkreisförmige Ausnehmung 11c im Taster 11 unterbrochen ist. Die Tastfläche 11a bzw. die entsprechende Tastkante verläuft wie aus Fig. 2 ersichtlich geradlinig und parallel zum angelegten Ski 14. In Längsrichtung der Kante 13 gesehen besteht zwischen dem Umfang des Fräsers 10 und der Tastkante 11a ein fester Abstand Z, der vorzugsweise kleiner als 1 mm ist. Dieser Abstand Z kann nahe bei 0 mm liegen. Wesentlich ist, dass die Kante 11a durch die Ausnehmung 11c nur soweit benötigt unterbrochen wird.The housing part 1b has two spaced-apart guideways 15 and 16 which, as shown in FIG. 1, contact the running surface 14a of the ski 14 are created. Also used to guide the hand-held device is a button 11 which, as shown in FIG. 1, bears against the outside 13a during the processing of a ski edge 13. The contact surface between the button 11 and the ski edge 13 forms a narrow strip and is preferably located below the position shown in FIG. 2. The button 11 is thus preferably on the inner half of the surface 13a. The button 11 has a guide surface 11a which is interrupted by a part-circular recess 11c in the button 11. As can be seen in FIG. 2, the touch surface 11a or the corresponding touch edge runs in a straight line and parallel to the ski 14 applied. In the longitudinal direction of the edge 13 there is a fixed distance Z between the circumference of the milling cutter 10 and the touch edge 11a, which is preferably less than 1 mm is. This distance Z can be close to 0 mm. It is essential that the edge 11a is interrupted by the recess 11c only as far as required.

Die teilkreisförmige Ausnehmung 11c besitzt einen Durchmesser, der nur wenig grösser ist als der Durchmesser des Umfangfräsers 10. Vor und nach dem geraden Bereich der Tastkante 11a schliesst sich ein Bereich 11b an, der mit zunehmendem Abstand zum Umfangfräser 10 einen zunehmenden Abstand zur anliegenden Skikante 13 aufweist. Der gerade Bereich 11a ist somit vergleichsweise kurz. Die Neigung des Bereichs 11b zum Bereich 11a liegt im Bereich von etwa 0 bis 30°.The part-circular recess 11c has a diameter which is only slightly larger than the diameter of the circumferential cutter 10. Before and after the straight region of the tracing edge 11a, there is an area 11b which, with an increasing distance from the circumferential cutter 10, an increasing distance from the adjacent ski edge 13 having. The straight region 11a is therefore comparatively short. The inclination of the area 11b to the area 11a is in the range of approximately 0 to 30 °.

Die Seiten 13a der Kanten 13 besitzen zur Belagsseite 14a einen Winkel, der im Bereich zwischen 90° und 60° liegt. Um dieser Neigung und einer entsprechenden konischen Bearbeitung der Skikanten 13 Rechnung zu tragen, ist entweder der Umfangfräser 10 mit einer entsprechenden Neigung im Gehäuse 1 gelagert oder wird ein entsprechend konischer Fräser eingesetzt. Ein Auswechseln des Fräsers 10 ist wie oben erläutert ohne weiteres und ohne Werkzeug möglich.The sides 13a of the edges 13 have an angle to the covering side 14a which is in the range between 90 ° and 60 °. In order to take this inclination and a corresponding conical processing of the ski edges 13 into account, either the circumferential cutter 10 is mounted in the housing 1 with a corresponding inclination or a correspondingly conical cutter is used. As explained above, the milling cutter 10 can be replaced easily and without tools.

Wie aus Fig. 1 ersichtlich, ist am Gehäuseteil 1b ein Sicherungsnocken 12 angeformt, der einerseits eine nicht beabsichtigte Berührung des Fräsers 10 verhindert und der anderseits ein zu tiefes Nachfräsen der Kanten 13 durch einen Anschlag am Ski 14 verhindert.As can be seen from FIG. 1, a securing cam 12 is formed on the housing part 1b, which on the one hand prevents the milling cutter 10 from unintentional contact and on the other hand prevents the edges 13 from being too deeply milled by a stop on the ski 14.

Damit von den Skikanten 13 abgearbeitete Brauen weggeführt werden können, besitzt der Körper 8 über dem Taster 11 eine sich in Längsrichtung der Kante 11a erstreckende Ausnehmung 8a.So that brows worked off from the ski edges 13 can be guided away, the body 8 has a recess 8a extending over the button 11 in the longitudinal direction of the edge 11a.

Die in den Figuren 3 und 4 gezeigte Ausführung unterscheidet sich bezüglich der Lagerung des Fräsers 10 von der oben beschriebenen Ausführung. Hier ist der Fräser 10 einerseits in einem fest mit dem Gehäuse 1 verbundenen Tastkörper 8' und anderseits in einem lösbar mit dem Tastkörper 8' verbundenen Deckel 17 gelagert. Der Deckel 17 ist über ein Gewinde 20 oder eine andere geeignete Verbindung mit dem Tastkörper 8' verbunden und kann zum einfachen Auswechseln des Fräsers 10 mit einem in eine Ausnehmung 17a eingesetzten Sechskantschlüssel gelöst werden. Diese Lagerung zeichnet sich durch eine besonders genaue und stabile Ausrichtung des Fräsers 10 bezüglich der Tastkante 11a aus, wobei zudem das Auswechseln des Fräsers besonders einfach ist. Das Handgerät ist über ein elektrisches Kabel 18 mit einer elektrischen Energiequelle verbunden und kann an einem Schalter 19 ein- und ausgeschaltet werden.The embodiment shown in FIGS. 3 and 4 differs in terms of the mounting of the milling cutter 10 from the embodiment described above. Here, the milling cutter 10 is mounted on the one hand in a probe body 8 'which is fixedly connected to the housing 1 and on the other hand in a cover 17 which is detachably connected to the probe body 8'. The cover 17 has a thread 20 or another suitable connection is connected to the probe body 8 'and can be released for easy replacement of the milling cutter 10 with a hex key inserted into a recess 17a. This mounting is characterized by a particularly precise and stable alignment of the milling cutter 10 with respect to the touch edge 11a, and the milling cutter is also particularly easy to replace. The hand-held device is connected to an electrical energy source via an electrical cable 18 and can be switched on and off at a switch 19.

Trotz der erheblichen Vorteile des erfindungsgemässen Handgerätes ist dieses ersichtlich mit verhältnismässig wenigen, einfachen und robusten Bauteilen realisierbar. Es wurde damit ein Handgerät geschaffen, welches nicht nur sehr bedienungsfreundlich ist, sondern aufgrund seiner einfachen und robusten Ausführbarkeit wegen kostengünstig und betrieblich äusserst zuverlässig ist.Despite the considerable advantages of the hand-held device according to the invention, it can obviously be realized with relatively few, simple and robust components. A hand-held device was thus created which is not only very user-friendly, but is also extremely reliable due to its simple and robust design because it is inexpensive and operationally reliable.
