Abstract

An electric hand plane (1) with a planing depth adjuster with readable planing depth indication comprises a wedge-shaped body (9), the lower edge surface (20) of which bears on a workpiece (10) and the upper wedge surface (19) of which supports the plane housing (2). A device generates a clamping force between the upper wedge surface (19) and the matching counter-surface (21) of the plane housing (2), where the relative position of the wedge-shaped body (9) to the plane housing (2) is determined by means of a scale (36) and where it is possible with a single handle (12) to both release the clamping force during the adjustment process and move the wedge-shaped body (9). The planing depth can be finely adjusted in a controlled manner because the handle (12) is coupled to actuating components (16, 33) by means of the movement of which, especially their rotation, the wedge-shaped body (9) is moved in relation to the plane housing (2).

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem elektrischen Handhobel nach der Gattung des Anspruchs 1.The invention relates to an electric hand plane according to the preamble of claim 1.

Durch die US-A-4 555 850 ist ein gattungsgemäßer Handhobel bekannt. Dessen Hobeltiefeneinstellvorrichtung mit ablesbarer Hobeltiefe wird mittels einer einzigen Handhabe durchgeführt, die mit einem keilförmigen Körper gekoppelt ist, der an der Unterseite des Handhobels in der Art einer schiefen Ebene hin und her schiebbar ist. Bei diesem Handhobel ist die Hobeltiefeneinstellung auf verhältnismäßig einfacher Art und Weise, mit geringem konstruktivem und herstellungsmäßigem Aufwand gelöst. Dieser Handhobel hat allerdings den Nachteil, daß ein genaues Einstellen der Hobeltiefe verhältnismäßig viel Gefühl und Zeitaufwand erfordertA generic planer is known from US-A-4 555 850. Whose planing depth setting device with readable planing depth is carried out by means of a single handle which is coupled to a wedge-shaped body which can be pushed back and forth in the manner of an inclined plane on the underside of the hand plane. With this hand planer, the planing depth adjustment is achieved in a relatively simple manner, with little design and manufacturing effort. However, this hand planer has the disadvantage that an exact adjustment of the planing depth requires a lot of feeling and time

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemäße elektrische Handhobel mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß die Hobeltiefe besonders genau, kontrolliert und schnell einstellbar ist.The electric planer according to the invention with the characterizing features of claim 1 has the advantage that the planing depth is particularly precise, controlled and quickly adjustable.

Durch die DE-OS 34 41 943 ist ein elektrischer Handhobel bekannt, der über ein Spiralnockengetriebe durch Drehen seiner Zusatzhandhabe ein Verschieben des keilförmigen Körpers zur Einstellung der Spantiefe ermöglicht. Das Spiralnockengetriebe besteht aus einer Vielzahl aufwendig herzustellender Teile. Dadurch sind die Herstellungskosten für den bekannten Handhobel hoch. Außerdem neigt das Spiralnockengetriebe infolge von eintretenden Hobelspänen und Staub zum Blöckieren.From DE-OS 34 41 943 an electric hand planer is known which enables the wedge-shaped body to be adjusted to adjust the depth of cut by means of a spiral cam gear by rotating its additional handle. The spiral cam gear consists of a large number of parts that are difficult to manufacture. As a result, the manufacturing costs for the known planer are high. In addition, the spiral cam gear tends to block due to incoming wood shavings and dust.

Die verbesserte Handlichkeit erhöht den Gebrauchswert des Handhobels so wesentlich, daß demgegenüber der erhöhte Konstruktions- und Herstellungsaufwand vernachlässigbar gering ist.The improved manageability increases the practical value of the hand plane so significantly that, in contrast, the increased design and manufacturing effort is negligible.

Weitere, vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.

Zeichnungdrawing

Ausführungsbeispiele der Erfindung sind in der nachfolgenden Beschreibung anhand der zugehörigen Zeichnung näher erläutert.Exemplary embodiments of the invention are explained in more detail in the following description with reference to the accompanying drawing.

Es zeigen Figur 1 eine Seitenansicht eines erfindungsgemäßen Handhobels, Figur 2 eine seitliche Schnittdarstellung des vorderen Bereichs des Handhobels und Figur 2 die Draufsicht auf diesen Bereich des Handhobels.FIG. 1 shows a side view of a hand plane according to the invention, FIG. 2 shows a sectional side view of the front area of the hand plane and FIG. 2 shows the top view of this area of the hand plane.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Das in Figur 1 dargestellte Ausführungsbeispiel eines Handhobels 1 zeigt dessen Aufbau, bestehend aus einem Hobelgehäuse 2 mit Haupthandgriff 3, in dem ein Ein-Aus-Schalter 4 angeordnet ist. Ein im hinteren Bereich des Handhobels 1 nach außen führendes Elektro-Kabel 5 ist im Inneren des Handhobelgehäuses 2 mit einem nicht im Einzelnen dargestellten Elektromotor verbunden. Der Sitz des Elektromotors ist durch die Kontur des Motorgehäuses 6 angedeutet.
Im Mittenbereich des Handhobels 1 ist eine schematisch dargestellte Hobelwalze mit Hobelmessern 7 erkennbar, oberhalb derer eine Spanauswurföffnung 8 angeordnet ist.
Der Handhobel 1 sitzt mit seinem im vorderen Bereich angeordneten keilförmigen Körper 9 auf einem Werkstück 10 auf. Dabei ist hier die maximale Spantiefe eingestellt, vorgegeben durch die Stufung in der Sohle 11 des Handhobels 1 nahe der Hobelwalze 7.
Vorn trägt der Handhobel 1 eine vordere Handhabe 12, mit deren Drehung um ihre Achse 13 sich der keilförmige Körper 9 verschiebt und die Spantiefe verändert.
The embodiment of a hand planer 1 shown in FIG. 1 shows its construction, consisting of a planer housing 2 with a main handle 3, in which an on-off switch 4 is arranged. An electric cable 5 leading to the outside in the rear area of the hand plane 1 is connected in the interior of the hand plane housing 2 to an electric motor, not shown in detail. The seat of the electric motor is indicated by the contour of the motor housing 6.
A schematically represented planing roller with planing knives 7 can be seen in the center area of the hand plane 1, above which a chip ejection opening 8 is arranged.
The hand planer 1 sits on a workpiece 10 with its wedge-shaped body 9 arranged in the front region. The maximum cutting depth is set here, specified by the grading in the Sole 11 of the planer 1 near the planing roller 7.
At the front, the planer 1 carries a front handle 12, with its rotation about its axis 13 the wedge-shaped body 9 moves and the depth of cut changes.

Der in der Figur 2 gezeigte Vorderbereich des Handhobels 1 zeigt dessen Hobelgehäuse 2 mit der nach oben über das Hobelgehäuse 2 hinausragenden Handhabe 12, die auch als Zusatzhandgriff dient. Die Handhabe 12 ist um die Achse 13 drehbar und in einer langlochartigen Ausnehmung 15 des Hobelgehäuses 2 verschiebbar. Die Handhabe 12 ragt mit einem zylinderartigen als Zahnwalze 16 ausgestalteten Fortsatz in das Hobelgehäuse 2 hinein. Die Zahnwalze 16 ragt mit ihrem freien Ende 17 in eine Aufnahmebohrung 18 des keilförmigen Körpers 9. Dieser hat eine obere Keilfläche 19 und eine untere Abstützfläche 20. Mit der oberen Keilfläche 19 ist der keilförmige Körper 9 an der schiefebenen Gegenfläche 21 des Hobelgehäuses 2 verschiebbar gelagert.
Die Aufnahmebohrung 18 befindet sich in einem tubusartigen Fortsatz 22 des keilförmigen Körpers 9, in dem die als Schraubbolzen ausgestaltete Achse 13 mit einem Sechskantkopf 23 drehfest angeordnet ist. Die Achse 13 durchtritt zentral die Zahnwalze 16 sowie die Handhabe 12, an der sie mit ihrem freien Ende axial gesichert ist. Dazu ist die Achse 13 an ihrem freien Ende mit einem Gewinde 24 versehen, auf das eine Sechskantmutter 25 geschraubt ist. Gegen die Sechskantmutter 25 stützt sich über eine Unterlegscheibe 26 eine Druckfeder 27 ab, die sich auf der der Unterlegscheibe 26 gegenüberliegenden Seite in eine Stufenbohrung 28 der Handhabe 12 abstützt.
The front area of the planer 1 shown in FIG. 2 shows the planer housing 2 thereof with the handle 12 protruding upwards beyond the planer housing 2, which also serves as an additional handle. The handle 12 is rotatable about the axis 13 and slidable in an elongated hole 15 of the planer housing 2. The handle 12 projects into the planer housing 2 with a cylindrical extension configured as a toothed roller 16. The toothed roller 16 projects with its free end 17 into a receiving bore 18 of the wedge-shaped body 9. This has an upper wedge surface 19 and a lower support surface 20. With the upper wedge surface 19, the wedge-shaped body 9 is slidably mounted on the obliquely counter surface 21 of the planer housing 2 .
The receiving bore 18 is located in a tube-like extension 22 of the wedge-shaped body 9, in which the axis 13 designed as a screw bolt with a hexagon head 23 is arranged in a rotationally fixed manner. The axis 13 passes centrally through the toothed roller 16 and the handle 12, on which it is axially secured with its free end. For this purpose, the axis 13 is provided at its free end with a thread 24 onto which a hexagon nut 25 is screwed. A compression spring 27 is supported against the hexagon nut 25 via a washer 26, which is supported on the side opposite the washer 26 in a stepped bore 28 of the handle 12.

In einer zur Achse 13 parallelen Sackbohrung 29 ist eng geführt, axial verschiebbar ein Raststift 30 angeordnet, der sich mit seiner Rückseite gegen eine Feder 31 stützt und in eine der Rastausnehmungen 32 des Hobelgehäuses 2 ragt.
Die Zahnwalze 16 greift mit ihrem äußeren Zahnbereich in zwei parallel zueinander fest im Hobelgehäuse 2 angeordnete Zahnstangen 33, 34.
In a blind bore 29 parallel to the axis 13, a locking pin 30 is closely guided, axially displaceably arranged, which is supported with its rear side against a spring 31 and projects into one of the locking recesses 32 of the planer housing 2.
The toothed roller 16 engages with its outer tooth region in two toothed racks 33, 34 which are fixedly arranged parallel to one another in the planer housing 2.

Die untere, sohlenartige Keilfläche 20 des keilförmigen Körpers 9 ist einem nicht dargestellten Werkstück zugeordnet, bestimmt den Abstand der nichtdargestellten Hobelwalze zur Werkstückoberfläche und damit die Spantiefe. Je weiter also der keilförmige Körper 9 nach vorn verschoben wird, umso weiter nach oben verschiebt sich die untere Keilfläche 20 und desto größer wird die Spantiefe.The lower, sole-like wedge surface 20 of the wedge-shaped body 9 is assigned to a workpiece (not shown), determines the distance between the planing roller (not shown) and the workpiece surface and thus the cutting depth. Thus, the further the wedge-shaped body 9 is moved forward, the further upwards the lower wedge surface 20 moves and the greater the depth of cut.

Wird die Handhabe 12 um die Achse 13 gedreht, wälzt sich der äußere Zahnbereich der Zahnwalze 16 auf den Zahnbereichen der Zahnstangen 33, 34 ab. Dadurch wird infolge des Formschlusses die Rotation schlupffrei in eine Translation umgewandelt, so daß sich die Handhabe 12 gemeinsam mit der Zahnwalze 16, der Achse 13 und dem keilförmigen Körper 9 entlang der Zahnstangen 33, 34 bzw. entlang der langlochartigen Ausnehmung 15 verschiebt.If the handle 12 is rotated about the axis 13, the outer tooth region of the toothed roller 16 rolls on the tooth regions of the toothed racks 33, 34. As a result of the positive locking, the rotation is converted into a translation without slip, so that the handle 12 moves together with the toothed roller 16, the axis 13 and the wedge-shaped body 9 along the racks 33, 34 or along the slot-like recess 15.

Dabei ist der keilförmige Körper 9 mit seiner oberen Keilfläche 19 an der Gegenfläche 21 am Gehäuse 2 durch nicht dargestellte, parallel zur Verschieberichtung verlaufende Rippen bzw. Nuten quer zur Verschieberichtung lagegesichert. Im gleichen Sinne ist die Handhabe 12 in der langlochartigen Ausnehmung 15 des Hobelgehäuses 2 gegen ein Ausweichen quer zur Verschieberichtung zumindest an zwei gegenüberliegenden Seiten geführt, so daß die Zahnwalze 16 stets mit geringem Spiel gegen die Zahnstangen 33, 34 gehalten wird.Here, the wedge-shaped body 9 is secured in position with its upper wedge surface 19 on the counter surface 21 on the housing 2 by ribs or grooves, not shown, running parallel to the direction of displacement, transversely to the direction of displacement. In the same sense, the handle 12 is guided in the slot-like recess 15 of the planer housing 2 against evasion transversely to the direction of displacement at least on two opposite sides, so that the toothed roller 16 is always held against the racks 33, 34 with little play.

Weil die Achse 13 die Handhabe 12 und/oder den keilförmigen Körper 9 an entgegengesetzten Enden axial federnd verschieblich festhält, streben die Handhabe 12 und der keilförmige Körper 9 aufeinander zu und spannen dabei zwischeneinander das Hobelgehäuse 2 ein. Dadurch besteht ein elastischer Längenausgleich für die Position des keilförmigen Körpers 9 bezüglich der Achse 13 bzw. bezüglich der Handhabe 12. Bei jeder Hobeltiefenverstellung wird der keilförmige Körper 9 fest an die schiefebene Gegenfläche 21 des Gehäuses 2 gezogen und kann allen Positionsänderungen normal zum Hobelgehäuse 2 spielfrei folgen.Because the axis 13 axially resiliently holds the handle 12 and / or the wedge-shaped body 9 at opposite ends, the handle 12 and the wedge-shaped body 9 strive towards one another and clamp the plane housing 2 between them. As a result, there is an elastic length compensation for the position of the wedge-shaped body 9 with respect to the axis 13 or with respect to the handle 12. With each planing depth adjustment, the wedge-shaped body 9 is pulled firmly against the obliquely level counter surface 21 of the housing 2 and can make any position changes to the planing housing 2 without play consequences.

In Figur 3 verdeutlicht die Draufsicht auf das Ausführungsbeispiel gemäß der Figur 2 die Anordnung der Handhabe 12 sowie der Rastausnehmungen 32. Außerdem ist ein drehfest an der Achse 13 angeordneter, zeigerartiger Markierungsträger 35 zu erkennen, dessen Lage bezüglich einer Skala 36 ein genaues Einstellen bestimmter Spantiefenmaße zwischen 0 und 1,5 mm erlaubt. Außerdem ist mit P eine "Parkstellung" bezeichnet, in der der Handhobel 1 abgesetzt werden kann, ohne daß Verletzungsgefahr an der eventuell unbeabsichtigt inganggesetzten Hobelwalze 7 mit Hobelmessern besteht.In FIG. 3, the top view of the exemplary embodiment according to FIG. 2 illustrates the arrangement of the handle 12 and the latching recesses 32. In addition, a pointer-like marking carrier 35, which is arranged on the axis 13 in a manner fixed against rotation, whose position with respect to a scale 36 enables an exact setting of certain chip depth dimensions allowed between 0 and 1.5 mm. In addition, P designates a "parking position" in which the planer 1 can be set down without the risk of injury to the planing roller 7 with planing knives which may have been started unintentionally.

Bei einem nicht dargestellten Ausführungsbeispiel der Erfindung ist an Stelle der Zahnwalze und der Zahnstangen an der Handhabe ein Kurbelgetriebe angeordnet, das sich im Inneren des Hobelgehäuses abstützt und im Prinzip die gleiche Wirkung hat wie das Zahngetriebe.In an embodiment of the invention, not shown, a crank gear is arranged on the handle instead of the toothed roller and the toothed racks, which is supported in the interior of the planer housing and in principle has the same effect as the toothed gear.

Bei einem weiteren nicht dargestellten Ausführungsbeispiel ist anstelle der Achse gemäß Figur 2 ein die Handhabe tragender Schwenkhebel mit einem Ende im keilförmigen Körper gelenkig gelagert. Nahe dem Lager stützt sich der Schwenkhebel an einer gehäusefesten Achse wippenartig am Gehäuse ab. Dadurch wird ein zweiarmiger Hebel gebildet, dessen Schwenkbewegung der keilförmige Körper folgen muß. Durch-Schwenken der Handhabe in und entgegen der Vorschubrichtung wird der keilförmige Körpers verschoben. Ein elastischer Längenausgleich zwischen dem Schwenkhebel und dem keilförmigem Körper ist analog zum Ausführungsbeispiel nach Figur 2 herstellbar.In a further exemplary embodiment, not shown, instead of the axis according to FIG. 2, a pivot lever carrying the handle is articulated with one end in the wedge-shaped body. Near the bearing, the swivel lever is supported on the housing on a shaft that is fixed to the rocker. This forms a two-armed lever, the pivoting movement of which must follow the wedge-shaped body. The wedge-shaped body is displaced by pivoting the handle in and against the feed direction. An elastic length compensation between the pivot lever and the wedge-shaped body can be produced analogously to the exemplary embodiment according to FIG. 2.
