Abstract
Description
Die Erfindung bezeichnet eine Hubsägemaschine mit einer Hubzahleinstellung für die Hubfrequenz des sich hin- und herbewegenden Hubsägeblattes, insbesondere eine Handstichsäge oder eine Säbelsäge.The Invention refers to a Hubsägemaschine with a Hubzahleinstellung for the stroke frequency of the reciprocating hub saw blade, in particular a handstitch saw or a saber saw.
Bei einfachen Handstichsägen ist die Hubzahl konstant durch die praktisch konstante Drehzahl des Elektromotors vorgegeben.at simple hand jigsaws, the stroke rate is constant through the practically constant speed of the electric motor specified.

Die Aufgabe der Erfindung besteht darin eine Hubsägemaschine mit einer robusten und intuitiv einfachen Realisierung der diskreten Hubzahleinstellung bereitzustellen.The The object of the invention is a Hubsägemaschine with a robust and intuitively simple realization of the discreet To provide stroke adjustment.
Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The The object is essentially achieved by the features of claim 1 solved. Advantageous developments emerge from the Dependent claims.
So weist eine zur Hin- und Herbewegung eines Hubsägeblattes geeignete Hubsägemaschine ein handhabbares Gehäuse, einen Elektromotor, eine Motorsteuerung und einen von aussen manuel versetzbaren Drehknopf zur Einstellung einer vorwählbaren Hubzahl auf, der mit einem Regelwiderstand verbunden ist, welcher mit der Motorsteuerung verbunden ist, wobei die Motorsteuerung ein Rechenmittel enthält, welches eine Stufenabbildung eines Verdrehwinkels des Drehknopfes in die Hubzahl enthält.So has one for reciprocating a Hubsägeblattes suitable Hubsägemaschine a manageable housing, an electric motor, a motor control and an externally manuel displaceable Rotary knob for setting a preselectable number of strokes, which is connected to a variable resistor which is connected to the motor control is, wherein the motor controller includes a computing means, which is a step image of a rotation angle of the knob included in the number of strokes.
Durch die Verwendung eines Drehknopfes zur Einstellung der Hubzahl ist diese intuitiv einfach ausgebildet, wobei vermittelt über die Stufenabbildung des Rechenmittels eine gegenüber geringem Winkelversatz robuste Vorwahl der optimalen Hubzahlstufe erfolgt.By the use of a knob to adjust the number of strokes is This intuitively trained simply, being conveyed via the step image of the computing means one against a slight angular misalignment Robust preselection of the optimal Hubzahlstufe done.
Vorteilhaft liegen über die Hälfte der Hubzahlstufen (im Weiteren die obere Hälfte) innerhalb des oberen Drittels des Hubzahlbereiches, wodurch dort eine besonders feine Hubzahlstufung ermöglicht ist.Advantageous are more than half of the number of strokes (hereinafter the upper half) within the upper third of the stroke rate range, whereby a particularly fine Hubzahlstufung is possible there.
Vorteilhaft ist die obere Hälfte der Hubzahlstufen über einen Verdrehwinkelbereich auswählbar, der sich zumindest über zwei Drittel des maximalen Verdrehwinkels des Regelwiderstandes erstreckt, wodurch der Winkelabstand für die Vorwahl der oberen Hälfte der Hubzahlstufen gespreizt ist.Advantageous is the upper half of the number of strokes over one Twist angle range selectable, at least about two-thirds of the maximum angle of rotation of the variable resistor extends, whereby the angular distance for the area code of upper half of Hubzahlstufen is spread.
Vorteilhaft ist das obere Viertel des Hubzahlbereiches in der Hubzahl bezüglich des Verdrehwinkels des Drehknopfes (und somit des Regelwiderstandes) linear wachsend gestuft, wodurch die obere Hälfte der Hubzahlstufen gleichmässig beabstandet vorwählbar ist.Advantageous is the upper quarter of the Hubzahlbereiches in the number of strokes with respect the angle of rotation of the knob (and thus the resistance) graded linearly increasing the upper half of the stroke rate steps evenly spaced preselected.
Vorteilhaft sind die unteren drei Viertel des Hubzahlbereiches in der Hubzahl bezüglich des Verdrehwinkels des Drehknopfes (und somit des Regelwiderstandes) degressiv wachsend (bspw. wie eine Logarithmusfunktion) gestuft, wodurch über die untere Hälfte der Hubzahlstufen bei kleinem Verdrehwinkel des Drehknopfes (und somit des Regelwiderstandes) ein grosser Hubzahlbereich vorwählbar ist.Advantageous are the lower three quarters of the stroke rate range in the number of strokes with respect to the angle of rotation of the knob (and thus of the variable resistor) decreasingly increasing (for example like a logarithmic function) graded, thereby over the lower half of the Hubzahlstufen at a small angle of rotation of the rotary knob (and thus the resistance) a large Hubzahlbereich is preselected.
Die Erfindung wird bezüglich eines vorteilhaften Ausführungsbeispiels näher erläutert mit:The Invention will be with respect to an advantageous embodiment explained in more detail with:
