Description

Die Erfindung betrifft eine Halterung für einen Handbandschleifer zum stationären Betrieb, mit einem Rahmen, in dem der Handbandschleifer lösbar befestigt werden kann und die eine vertikale und eine horizontale Standfläche für den Handbandschleifer schafft.The invention relates to a holder for a hand belt sander for stationary operation, with a frame in which the hand belt sander can be detachably attached and which creates a vertical and a horizontal footprint for the hand belt sander.

Es ist bekannt, Handbandschleifer dann, wenn sie in stationärem Betrieb verwendet werden sollen, in dafür geeigneten Rahmen bzw. Ständern zu befestigen. Diese aus Gründen der Standfestigkeit relativ großflächig ausgebildete Rahmen behindern jedoch den Bearbeitungsvorgang.It is known to fix hand-held belt grinders in frames or stands which are suitable for this purpose if they are to be used in stationary operation. However, these frames, which have a relatively large surface area for reasons of stability, hinder the machining process.

Der Erfindung liegt die Aufgabe zugrunde, eine Halterung für einen Handbandschleifer zu schaffen, die eine stabile Aufnahme eines Handbandschleifers im stationären Betrieb ermöglicht, die sich einfach handhaben läßt, eine einfache Befestigung des Handbandschleifers ermöglicht und die außerdem eine Bearbeitung auch von großflächigen Werkstücken nicht beeinträchtigt.The invention has for its object to provide a holder for a hand-held belt sander, which enables a stable mounting of a hand-held belt sander in stationary operation, which is easy to handle, enables simple attachment of the hand-held belt sander and which also does not impair the machining of large workpieces.

Die Erfindung besteht darin, daß als Rahmen ein Winkel vorgesehen ist, dessen beide, einen rechten Winkel zueinander bildende Schenkel je eine Standfläche bilden, wobei der erste Schenkel, der die Standfläche für den vertikalen Betrieb bildet, so ausgebildet ist, daß er nicht über die von dem Schleifband gebildete Arbeitsfläche bei montiertem Handbandschleifer vorsteht. Ein solcher als Winkel ausgebildeter Rahmen kann einfach durch Kippen von einer horizontalen in eine vertikale Lage geschwenkt werden und bietet somit die Möglichkeit, den Handbandschleifer sehr einfach in eine der beiden Positionen zu stellen. Der Winkel kann stabil und entsprechend schwer ausgebildet werden, so daß er eine gute Standfestigkeit beim Abstellen auf einer Arbeitsunterlage o.dgl. bietet. Dadurch, daß der erste Schenkel, der als Standfläche für den vertikalen Betrieb ausgebildet ist, nicht über die von dem Schleifband gebildete Arbeitsfläche hinaus ragt, wird die Bearbeitung großer Flächen ohne Behinderung möglich.The invention is that an angle is provided as a frame, the two legs forming a right angle to each other each form a standing surface, the first leg, which forms the standing surface for vertical operation, is designed so that it does not have the working surface formed by the sanding belt protrudes when the hand belt sander is mounted. Such a frame, which is designed as an angle, can be swiveled from a horizontal to a vertical position simply by tilting and thus offers the possibility of placing the hand-held belt sander very easily in one of the two positions. The angle can be designed to be stable and correspondingly heavy, so that it has a good stability when it is placed on a work surface or the like. offers. The fact that the first leg, which is designed as a standing surface for vertical operation, does not protrude beyond the working surface formed by the grinding belt, makes it possible to machine large surfaces without hindrance.

Wenn die Schenkel mit in ihrem Verlauf den Handbandschleiferkonturen angepaßten Auflagenflächen versehen sind, kann der Handbandschleifer im wesentlichen durch diese Auflageflächen allein gehalten und abgestützt werden. Es genügt dann, lediglich zur Lagefixierung eine Schraube vorzusehen, so daß insgesamt die Montage des Handbandschleifers in der Halterung sehr einfach möglich ist.If the legs are provided with support surfaces which are adapted to the contours of the hand-held belt grinder, the hand-held belt grinder can essentially be held and supported solely by these support surfaces. It is then sufficient to provide only a screw to fix the position, so that the assembly of the hand-held sander in the holder is very simple.

In vorteilhafter Weiterbildung der Erfindung ist vorgesehen, daß die Breite der Schenkel etwa der Breite des Handbandschleifers entspricht und daß auf einem Schenkel (zweiter Schenkel) zwei Lagerbacken zur Abstützung des Motorgehäuses vorgesehen sind. Diese Lagerbacken bilden vorteilhaft jeweils -eine Stützstelle für den vertikalen und für den horizontalen Betrieb und sind an den Auflagestellen des Motorgehäuses mit Gummipuffern o.dgl. versehen. Damit wird der Handbandschleifer direkt an seinem schwersten Teil, dem Motorgehäuse, abgestützt und kann dadurch zuverlässig gelagert werden. Zur Vibrationsdämpfung dienen dann die Gummipuffer an den Auflagestellen. Während die Lagerbacken im zweiten Schenkel ausgebildet sind, genügt es, am ersten Schenkel als Auflagefläche eine eine Einbuchtung schaffende Stütze auszubilden. Auf dieser Stütze kann sich der Handbandschleiter beispielsweise mit der Stirnseite seines Griffes auflegen. Dort kann dann auch die Fixierschraube die Verbindung zur Halterung herstellen. Die Einbuchtung wird dabei vorteilhaft so beschaffen, daß sie den Kopf der Fixierschraube so aufnehmen kann, daß diese nicht über die vom ersten Schenkel gebildete Auflagefläche übersteht. Durch diese Maßnahme wird sichergestellt, daß der Kopf der Fixierschraube das Aufstellen für den vertikalen Betrieb nicht behindert.In an advantageous development of the invention it is provided that the width of the legs corresponds approximately to the width of the hand-held belt sander and that two bearing jaws are provided on one leg (second leg) to support the motor housing. These bearing jaws each advantageously form a support point for vertical and horizontal operation and are provided with rubber buffers or the like at the support points of the motor housing. Mistake. This supports the hand belt sander directly on its heaviest part, the motor housing and can therefore be stored reliably. The rubber buffers at the support points then serve to dampen vibrations. While the bearing jaws are formed in the second leg, it is sufficient to form a support that creates an indentation on the first leg as a support surface. The hand strap ladder can lay down on this support, for example, with the front of its handle. The fixing screw can then also establish the connection to the holder there. The indentation is advantageously provided in such a way that it can accommodate the head of the fixing screw in such a way that it does not protrude beyond the contact surface formed by the first leg. This measure ensures that the head of the fixing screw does not hinder the installation for vertical operation.

Bei einer vorteilhaften Weiterbildung der Erfindung wird am Winkel mindestens ein Träger für eine aufschraubbare, eine Anschlagfläche auf der Schleifbandfläche schaffende Zusatzeinrichtung vorgesehen. Diese abnehmbare Anschlagfläche kann dann mit dem Winkel beispielsweise verschraubt werden, so daß sie eine sichere Führung eines zu bearbeitenden Werkstückes über die Arbeitsfläche des Schleifbandes möglich macht. Um die Aufnahme des Handbandschleifers selbst im Winkel nicht zu beeinträchtigen und zur besseren Befestigung ist es dann günstig, wenn dieser Träger von einem an den Winkel angeformten, seitlich über die Kontur des Winkels abstehenden Elementes gebildet wird.In an advantageous development of the invention, at least one support for an additional device which can be screwed on and creates a stop surface on the grinding belt surface is provided on the bracket. This removable stop surface can then be screwed to the angle, for example, so that it makes it possible to securely guide a workpiece to be machined over the working surface of the grinding belt. In order not to adversely affect the inclusion of the hand-held belt grinder itself and for better fastening, it is then advantageous if this carrier is formed by an element which is molded onto the angle and protrudes laterally beyond the contour of the angle.

Vorteilhaft kann es auch sein, wenn am freien Ende des ersten Schenkels eine eine Arbeitsfläche schaffende und die Arbeitsfläche des Schleifbandes umgebende Platte schwenkbar befestigt ist. Diese Platte kann dann ebenfalls abnehmbar befestigt sein und kann eine großflächige Arbeitsfläche schaffen.It can also be advantageous if a plate that creates a work surface and surrounds the work surface of the grinding belt is pivotally attached to the free end of the first leg. This plate can then also be removably attached and can create a large work surface.

In manchen Fällen kann es wünschenswert sein, den Winkel selbst noch gegenüber einer Arbeitsfläche zu fixieren. Dies ist dann einfach möglich, wenn die beiden Schenkel mit Bohrungen und Vertiefungen zum Ansetzen einer Schraubklammer, über die der Winkel auf eine Arbeitsunterlage aufspannbar ist, versehen sind. Somit kann die Halterung sehr fest mit einer Abstellfläche verbunden sein.In some cases it may be desirable to fix the angle itself in relation to a work surface. This is easily possible if the two legs are provided with bores and depressions for attaching a screw clamp, by means of which the angle can be clamped onto a work surface. Thus, the bracket can be very firmly connected to a shelf.

Die Vorteile und Merkmale der Erfindung ergeben sich auch aus den in den Figuren dargestellten Ausführungsbeispielen, die im folgenden erläutert werden. Es zeigt:

  • Fig. 1 eine seitliche Ansicht einer erfindungsgemäßen Halterung,
  • Fig. 2 eine Draufsicht auf die in Fig. 1 dargestellte erfindungsgemäße Halterung,
  • Fig. 3 einen Querschnitt durch eine erfindungsgemäße Halterung mit in dieser aufgenommene Handbandschleifmaschine in horizontaler Arbeitsstellung und
  • Fig. 4 eine erfindungsgemäße Halterung mit aufgenommener Handbandschleifmaschine mit vertikaler Arbeitsstellung.
The advantages and features of the invention also result from the exemplary embodiments illustrated in the figures, which are explained below. It shows:
  • 1 is a side view of a bracket according to the invention,
  • 2 is a plan view of the holder according to the invention shown in FIG. 1,
  • Fig. 3 shows a cross section through a holder according to the invention with a hand-held belt grinder incorporated therein in the horizontal working position and
  • Fig. 4 shows a holder according to the invention with a hand-held belt grinder with a vertical working position.

Ein Ausführungsbeispiel einer erfindungsgemäßen Halterung ist in Fig. 1 im ganzen mit 1 bezeichnet. Es ist zu erkennen, daß die Halterung 1 als Winkel ausgebildet ist und zwei Schenkel 2 und 3 aufweist, die einstückig miteinander verbunden sind. Der erste Schenkel 2 bildet dabei eine Stützfläche 2a, wenn der Handbandschleifer in die Halterung eingehängt wird und vertikal betrieben werden soll, der zweite Schenkel 3 bildet die Auflagefläche 3a, wenn der Handbandschleifer im horizontalen Betrieb arbeiten soll. Auf den Schenkeln 2 und 3 sind den Konturen des aufzunehmenden Handbandschleifers, der in Fig. 3 und 4 gezeigt ist, angepaßte Auflageflächen.vorgesehen, an denen sich entsprechende Teile des Handbandschleifers abstützen. Diese Auflageflächen sind im wesentlichen die Stütze 5 und die Lagerbacken 4, auf denen sich der Handbandschleifer in aufgenommener Stellung sowohl im vertikalen als auch im horizontalen Betrieb abstützt. Durch Kippen dieser Halterung auf eine der beiden Standflächen 2a oder 3a kann der Handbandschleifer sehr einfach in die jeweils gewünschte, beim stationären Betrieb einzunehmende Position gebracht werden.An embodiment of a holder according to the invention is generally designated 1 in FIG. 1. It can be seen that the holder 1 is designed as an angle and has two legs 2 and 3, which are integrally connected to one another. The first leg 2 forms a support surface 2a when the hand-held belt grinder is suspended in the holder and is to be operated vertically, the second leg 3 forms the support surface 3a when the hand-held belt grinder is to operate in horizontal operation. On legs 2 and 3 are 3 and 4, adapted to the contours of the hand-held belt grinder to be accommodated. Provided on which corresponding parts of the hand-held belt grinder are supported. These bearing surfaces are essentially the support 5 and the bearing jaws 4, on which the hand-held belt grinder is supported in the recorded position both in vertical and in horizontal operation. By tilting this holder onto one of the two standing surfaces 2a or 3a, the hand belt sander can be brought very easily into the desired position to be assumed during stationary operation.

Die Breite der Schenkel 2 und 3 entspricht etwa der Breite des aufzunehmenden Handbandschleifers, so daß in geeignetem Abstand die beiden Lagerbacken 4a und 4b (vgl. Fig. 2) vorgesehen sein können. Auf diesen Lagerbacken 4a und 4b sind jeweils Bohrungen 7 vorgesehen, in die Gummipuffer 15 eingespannt werden können.The width of the legs 2 and 3 corresponds approximately to the width of the hand-held belt grinder, so that the two bearing jaws 4a and 4b (cf. FIG. 2) can be provided at a suitable distance. Holes 7 are provided in each of these bearing jaws 4a and 4b, in which rubber buffers 15 can be clamped.

Der Bereich der Stütze 5 schafft eine Einbuchtung 10, in die in noch weiter unten beschriebener Weise eine Schraube aufgenommen werden kann, mit der der einzuhängende Handbandschleifer an die Stütze 5 geschraubt werden kann. Seitlich über die Kontur der Halterung überstehend ist ein Träger 6 einstückig mit der Halterung ausgebildet, der zum Aufschrauben einer Zusatzeinrichtung dienen kann. Wenn eine besonders stabile Befestigungsmöglichkeit für die Zusatzeinrichtung vorhanden sein soll, kann auch auf der in Fig. 2 dem dargestellten Träger 6 gegenüberliegenden Seite 3b ein ähnlicher oder gleicher Träger ausgebildet sein, der sich beispielsweise rippenartig vom Schenkel 2 weg in der Höhe der durch den Träger 6 gebildeten Befestigungsstelle erstrecken kann, wodurch dann eine Zusatzeinrichtung an zwei Seiten und damit besonders stabil abgestützt und befestigt werden kann.The area of the support 5 creates an indentation 10, into which a screw can be received in the manner described further below, with which the hand-held belt sander to be attached can be screwed to the support 5. Projecting laterally beyond the contour of the holder, a carrier 6 is formed in one piece with the holder, which can be used for screwing on an additional device. If there is to be a particularly stable fastening option for the additional device, a similar or identical carrier can also be formed on the side 3b opposite the carrier 6 shown in FIG. 2, which, for example, ribs away from the leg 2 at the height of the carrier 6 formed attachment point can extend, which then an additional device can be supported and attached on two sides and thus particularly stable.

Zur Erhöhung der Stabilität verbindet die beiden Schenkel 2 und 3 noch zusätzlich eine Querstrebe 25, die gleichzeitig auch zur Arretierung und als Anschlag für den Griff einer aufgenommenen Handbohrschleifmaschine dienen kann.To increase the stability, the two legs 2 and 3 additionally connect a cross strut 25, which can also serve for locking and as a stop for the handle of a hand-held grinder.

Anhand von Fig. 3 ist zu erkennen, wie ein Handbandschleifer 14 in der erfindungsgemäßen Halterung aufgenommen wird. Die Halterung ist dabei im Querschnitt dargestellt. Im Bereich des Motorgehäuses 16 bilden die Lagerbacken 4 die Stützstellen 9a und 9b, wobei Gummipuffer 15 die Vibrationsübertragung auf die Halterung beim Betrieb des Handbandschleifers dämpfen. Zur Fixierung der Position des Handbandschleifers ist die Fixierschraube 17 vorgesehen, die im Bereich der Stütze 5 von der Standfläche 2a (für den in Fig. 4 gezeigten vertikalen Betrieb) aus in die geschaffene Einbuchtung 10 eingesetzt wird und dort den Griff 21 des Handbandschleifers gegen die Stütze 5 verspannt. Die Einbuchtung 10 ist dabei so ausgebildet, daß der Kopf 17a der Fixierschraube 17 in der Einbuchtung 10 so aufgenommen werden kann, daß er nicht über die Fläche 2a übersteht.3 shows how a hand-held belt sander 14 is received in the holder according to the invention. The bracket is shown in cross section. In the area of the motor housing 16, the bearing jaws 4 form the support points 9a and 9b, with rubber buffers 15 damping the transmission of vibrations to the holder during operation of the hand-held belt sander. To fix the position of the hand-held belt grinder, the fixing screw 17 is provided, which is inserted in the area of the support 5 from the standing surface 2a (for the vertical operation shown in FIG. 4) into the indentation 10 created and there the handle 21 of the hand-held belt grinder against Support 5 braced. The indentation 10 is designed such that the head 17a of the fixing screw 17 can be received in the indentation 10 such that it does not protrude beyond the surface 2a.

Diese in Fig. 3 gezeigte Arbeitsstellung entspricht dem Betrieb, in dem der Handbandschleifer 14 eine horizontale Arbeitsfläche schafft. Um ihn gegenüber dem Arbeitstisch 11 besser zu fixieren, kann er mit Hilfe einer Spannklammer 12, die in eine entsprechende Vertiefung 8 (vgl. auch Fig. 1 und 2) eingreift, festgespannt werden.This working position shown in FIG. 3 corresponds to the operation in which the hand belt sander 14 creates a horizontal working surface. In order to fix it better in relation to the work table 11, it can be clamped with the aid of a clamping clip 12 which engages in a corresponding recess 8 (cf. also FIGS. 1 and 2).

Wie weiterhin aus Fig. 3 zu erkennen ist, ist der erste Schenkel 2 der Halterung so ausgebildet, daß er bei aufgenommenem Handbandschleifer 14 nicht über die von dem Schleifband gebildeten Arbeitsfläche E-E übersteht. Damit wird sichergestellt, daß Teile der Halterung das freie Bewegen auch von größeren Werkstücken über die Schleiferbandfläche nicht behindern.As can also be seen from FIG. 3, the first leg 2 of the holder is designed such that it does not protrude beyond the working surface E-E formed by the grinding belt when the hand belt sander 14 is picked up. This ensures that parts of the bracket do not hinder the free movement of larger workpieces across the grinder belt surface.

Um das Ablegen von Werkstücken einfacher möglich zu machen, ist in dem in Fig. 3 gezeigten Ausführungsbeispiel noch eine Arbeitsplatte 18 vorgesehen, die am freien Ende des ersten Schenkels 2 schwenkbar befestigt ist und eine Aussparung für das Schleifband bildet, so daß die Arbeitsplatte 18 das Schleifband umgibt. Die Arbeitsplatte 18 stützt sich über die Schraube 19 an geeigneten Stellen (Haken 26 und Schlitz 27) des Handbandschleifers ab.In order to make the placement of workpieces easier, a worktop 18 is provided in the embodiment shown in Fig. 3, which is pivotally attached to the free end of the first leg 2 and forms a recess for the grinding belt, so that the worktop 18 Sanding belt surrounds. The worktop 18 is supported on the screw 19 at suitable points (hook 26 and slot 27) of the hand-held belt sander.

Fig. 4 zeigt den in der erfindungsgemäßen Halterung aufgenommenen Handbandschleifer in einer vertikalen Arbeitsstellung, wobei sich auch in dieser Stellung die erfindungsgemäße Ausbildung des ersten Schenkels 2 vorteilhaft bemerkbar macht, da das Längsschleifen auch großer Flächen damit ohne weiteres möglich ist. Als Zusatzeinrichtung, die auf dem auch in Fig.1 und 2 dargestellten Träger 6 und gegebenenfalls eines weiteren, nicht dargestellten Trägers, über die Schraube 24 aufschraubbar ist, dient eine für das Werkstück 23 einen Anschlag schaffende, im ganzen mit 22 bezeichnete Vorrichtung, die es auch ermöglicht, verschiedene Winkel einzustellen, so daß am Werkstück auch entsprechende Neigungswinkel erhalten werden. Diese Zusatzeinrichtung 22 kann aber auch vom Träger 6 abgeschraubt werden und in einer Bohrung 27 am Handbandschleifer verankert werden, so daß eine Anschlagfläche quer zu der in Fig. 4 gezeigten geschaffen wird. Dann lassen sich z.B. größere Bretter mit Längsführung bearbeiten. Auch für diesen vertikalen Betrieb kann die Halterung über eine Spannklammer 12 auf einem Arbeitstisch 11 aufgespannt werden. Für die Spannklammer 12, die am freien Ende des ersten Schenkels 2 angesetzt ist, ist eine geeignete Bohrung 13 vorgesehen, in die die Spannklammer eingreift. Solche Bohrungen sind noch an weiteren, geeigneten Stellen der Halterung vorgesehen, so daß verschiedene Möglichkeiten zum Anbringen der Spannklammer bestehen.FIG. 4 shows the hand-held belt grinder accommodated in the holder according to the invention in a vertical working position, the configuration of the first leg 2 according to the invention also having an advantageous effect in this position, since longitudinal grinding of large surfaces is thus easily possible. As an additional device, which can be screwed onto the carrier 6, which is also shown in FIGS. 1 and 2, and possibly a further carrier, not shown, via the screw 24, a device, which is designated 22 as a stop, for the workpiece 23 is used it also enables different angles to be set, so that corresponding angles of inclination are also obtained on the workpiece. This additional device 22 can also be unscrewed from the carrier 6 and anchored in a bore 27 on the hand belt sander, so that a stop surface is created transversely to that shown in FIG. 4. Then e.g. Process larger boards with a longitudinal guide. For this vertical operation too, the holder can be clamped on a work table 11 by means of a clamping clip 12. A suitable bore 13 is provided for the clamp 12, which is attached to the free end of the first leg 2, into which the clamp engages. Such holes are also provided at other suitable locations on the holder, so that there are various options for attaching the tensioning clip.

Durch die Lagerung und Abstützung des Handbandschleifers am Motorgehäuse über die Spannbacken 4 wird der Schwerpunkt des Handbandschleifers etwa in der Mittelebene der durch den ersten Schenkel 2 gebildeten Standfläche gehalten, so daß sich ein recht stabiler Zustand erreichen läßt, ohne daß die gebildeten Standflächen sehr groß sein müssen.By storing and supporting the hand belt sander on the motor housing via the jaws 4, the center of gravity of the hand belt sander is held approximately in the central plane of the standing area formed by the first leg 2, so that a fairly stable condition can be achieved without the standing areas formed being very large have to.

Diese Halterung bietet insbesondere die Vorteile, daß sich ein Handbandschleifer ohne weiteres sehr einfach aufnehmen läßt, daß er nur an einer Stelle über eine Schraube fixiert werden muß und daß in sehr einfacher Weise ein Umbau von horizontalen in vertikalen Betrieb möglich ist. Auch behindern Teile der Halterung beim Schleifen großflächiger Werkstücke nicht die auszuführenden Bewegungen der Werkstücke, so daß insgesamt ein handlicher und praktischer, stationärer Betrieb eines Handbandschleifers mit der erfindungsgemäßen Halterung ermöglicht wird.This holder has the particular advantages that a hand-held belt sander can be easily picked up, that it is fixed at one point by a screw must and that a conversion from horizontal to vertical operation is possible in a very simple manner. Also parts of the holder do not hinder the movements of the workpieces to be carried out when grinding large-area workpieces, so that overall a handy and practical, stationary operation of a hand-held belt grinder with the holder according to the invention is made possible.
