Description

Die Erfindung geht aus von einem Handhobel nach der Gattung des Hauptanspruchs. Solche Handhobel sind schon bekannt, durch die CH-A-252181 oderdieAT-B-165140. Die Einstellvorrichtungen sind dort aber nur mittels zusätzlicher Messmittel schon beim Einstellen kontrollierbar und/oder relativ ungenau und nicht genügend stabil. Die Einstellarbeit erfordert ausserdem viel Geschicklichkeit, weil beim Festziehen der Klemmschraube stets wieder die aufgesuchte Stellung sich verändert. Dort wo das Einstellen mittels einer Feder erleichtert ist, können schon kleine Erschütterungen den Einstellerfolg wieder zunichte machen.The invention relates to a planer according to the type of the main claim. Such hand planes are already known from CH-A-252181 or AT-B-165140. However, the setting devices can only be checked during setting by means of additional measuring means and / or are relatively imprecise and not sufficiently stable. The adjustment work also requires a lot of skill, because when you tighten the clamping screw, the position you visit changes again and again. Wherever adjustment is made easier with a spring, even small vibrations can negate the setting success.

Der erfindungsgemässe Handhobel mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil eines äusserst einfachen Aufbaues und dennoch hoher Standfestigkeit bei leichter Handhabung. Die eingestellte Hobeltiefe ist ohne zusätzliche Mittel direkt von dem Teil der Maschine ablesbar, der zur Veränderung der Hobeltiefe eingestellt wird, weil die obere Fläche des Keils eine Skala hat, die an der ihr zugeordneten Gehäusekante abgelesen werden kann. Zusätzlich hat der Keil durch mindestens eine Führungsschiene und mindestens eine Führungsnut eine gute Führung. Die dem Handhobelgehäuse zuordnete Rastvorrichtung, die die verschiedenen Einstellungen für verschiedene Hobeltiefen mittels einer Feder sichert, indem sie den Keil in Eingriffsstellung zieht, macht einfaches, schnelles und sicheres Verstellen möglich.The planer according to the invention with the characterizing features of the main claim has the advantage of an extremely simple structure and yet high stability with easy handling. The set planing depth can be read directly from the part of the machine that is set to change the planing depth without additional means, because the upper surface of the wedge has a scale that can be read from the housing edge assigned to it. In addition, the wedge has good guidance through at least one guide rail and at least one guide groove. The locking device assigned to the planer housing, which secures the various settings for different planing depths by means of a spring by pulling the wedge into the engaged position, enables simple, quick and safe adjustment.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die Figur zeigt eine seitliche Teilansicht einer Handhobelmaschine mit der erfindungsgemässen Einstellvorrichtung, teilweise geschnitten.An embodiment of the subject of the invention is shown in the drawing and explained in more detail in the following description. The figure shows a partial side view of a hand planer with the adjusting device according to the invention, partially in section.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Es ist eine Handhobelmaschine 1 mit einem Handhobelgehäuse 2 gezeigt. Das Handhobelgehäuse 2 besitzt eine schräge Auflagefläche 3. An diese Auflagefläche ist ein Keil 4 angesetzt, der an seiner oberen Fläche eine Skala 5, eine Rasterung 6 und einen als Handhabe dienenden Steg 7 trägt. Neben diesem Steg 7 ist an der Oberfläche des Keils 4 noch eine Öse 8 angeordnet, in die eine Zugfeder 9 eingreifen kann. Ihr Widerlager findet diese Zugfeder 9 an einer Öse 10 an der Innenseite der oberen Wand des Handhobelgehäuses 2. Diese obere Gehäusewand besitzt auch einen Längsdurchbruch 11 durch den das Ende des Stegs 7 hindurchragt. Ein Steg 12 im Inneren des Handhobelgehäuses 2 besitzt eine Rastkante, mit der er in die Rasterung 6 eingreifen kann. Die Teilung der Rasterung 6 ist der Teilung der Skala 5 angepasst. Beide Teilungen geben ein entsprechendes Mass in Millimetern für die veränderliche Lage einer Auflagefläche 13 des Teils 4 an, die der eingestellten Hobeltiefe entspricht. Der Längsdurchbruch 11 gibt dem Steg 7, der als Handhabe oben aus dem Handhobelgehäuse 2 herausragt, zugleich eine Längsführung. Die Vorderkante des Handhobelgehäuses 2, die dem Ablesen der Skala 5 dient, ist mit 14 bezeichnet.A hand planer 1 with a hand planer housing 2 is shown. The hand planer housing 2 has an inclined support surface 3. A wedge 4 is attached to this support surface, which carries on its upper surface a scale 5, a grid 6 and a web 7 serving as a handle. In addition to this web 7, an eyelet 8 is also arranged on the surface of the wedge 4, in which a tension spring 9 can engage. Your abutment finds this tension spring 9 on an eyelet 10 on the inside of the upper wall of the planer housing 2. This upper housing wall also has a longitudinal opening 11 through which the end of the web 7 projects. A web 12 in the interior of the planer housing 2 has a locking edge with which it can engage in the grid 6. The division of the grid 6 is adapted to the division of the scale 5. Both divisions indicate a corresponding dimension in millimeters for the variable position of a support surface 13 of part 4, which corresponds to the planing depth set. The longitudinal opening 11 also gives the web 7, which protrudes as a handle from the planer housing 2 at the top, a longitudinal guide. The front edge of the planer housing 2, which is used to read the scale 5, is designated by 14.

Zum Einstellen der Hobeltiefe drückt man den Steg 7 soweit in das Handhobelgehäuse hinein, bis die Rasterung 6 des Keils 4 vom Steg 12 abgehoben ist. Danach verschiebt man mit dem Steg 7 den Keil 4 bis die gewünschte Hobeltiefe mittels der Kante 14 und der Skala 5 abzulesen ist. Lässt man nun den Steg 7 los, zieht die Zugfeder 9 die Rasterung 6 wieder in Eingriffsstellung mit dem Steg 12. Die eingestellte Hobeltiefe ist damit gesichert.To adjust the planing depth, press the web 7 into the planer housing until the grid 6 of the wedge 4 is lifted off the web 12. Then you move the wedge 4 with the web 7 until the desired planing depth can be read off using the edge 14 and the scale 5. If you now let go of the web 7, the tension spring 9 pulls the catch 6 back into the engagement position with the web 12. The planing depth set is thus secured.

Claims (3)

1. Portable plane, in particular a portable planing machine (1) designed as an electrically powered portable machine tool, with a setting device for the planing depth which makes the bearing surface located in front of the tool of the portable planing machine adjustable and the set planing depth readable, with the bearing surface (13) being the base of a wedge (4) which is adjustably fixed in front of the tool on an inclined surface (3) of the plane housing (2) and projects in the adjusting direction beyond an edge (14) of the portable plane housing (2) located above it, characterized in that
a) the upper surface of the wedge 4 projecting beyond the edge (14) of the portable plane housing (2) has a scale (5) on which the planing depth can be read by means of the housing edge (14),
b) the wedge (4) bears a handle (7) which projects up through a corresponding recess (11) in the portable plane housing (2) and thus gives the wedge (4) guidance in the portable plane housing,
c) the wedge (4) and portable plane housing (2) have an arresting device (12, 6) which secures arrested positions of the wedge (4) on the portable plane housing (2), which arrested positions correspond to various planing depths, and
d) the wedge (4) is firmly held by at least one spring (9) on the portable plane housing (2).
2. Portable plane according to Claim 1, characterized in that the surface of the wedge (4) protruding from beneath the housing edge (14) of the portable plane housing (2) bears a scale (5) attached by adhesive.
