Description

Zweifacher Fußantrieb für einfache Schleifsteine. Die Erfindung bildet einen zweifachen Füßantr.ieb für einfache Schleifsteine mit Gewichtswirkung des Antreibenden, bei welchem die Einzelpedale mit einem waagebalkenartigen, schwingbaren Hebel verbunden und dessen Endpunkte wieder infolge kardanischer Gelenke mit den Lenkstangen der Endkurbeln des Schleifsteines in Verbindung gebracht sind.Double foot drive for simple grindstones. The invention forms a double foot drive for simple grindstones with the weight effect of the Driving force, in which the individual pedals swing with a horizontal bar-like Lever connected and its end points again as a result of cardanic joints with the Handlebars of the end cranks of the grindstone are connected.

Die Zeichnung veranschaulicht den Antrieb in einer beispielsweisen Ausführung. Abb. i ist eine Seitenansicht; Abb.2 ist ein Querschnitt des Antriebs.The drawing illustrates the drive in an exemplary manner Execution. Fig. I is a side view; Fig 2 is a cross section of the drive.

Auf dem Gestell i ist eine von einem ausziehbaren Wasserbehälter 2 unterfangene Schleifsteinscheibe 3 drehbar gelagert, dessen Welle und Kurbeln infolge Lenkstangen und kardanischer Gelenke 5 mit einem auf einer Achse 6 waagebalkenförmig gelagerten Hebel 7 verbunden sind. Durch den Hebel 7 führen zwei einerseits mittels Gelenke 8 am Gestell i befestigte und anderseits Einzelpedale 9, io tragende frei schwingende Hebel i i. die durch Zugfedern i2 selbsttätig gehoben' werden. Über der Schleifsteinscheibe 3 ist eine durch umsteckbare Bolzen 13 zu verändernde Armstütze i4.- vertikal verschieb-und feststellbar angeordnet. Durch Treten der Pedale 9, io und wechselndes Auf- und Abbewegen derselben in Pfeilrichtung A wird der Hebel 7 in Pf eilr ichtung B waagebalkenartig geschwungen und so durch die Übertragung der Gestänge q. der Schleifstein gedreht. Infolge der Anordnung der verstellbaren Armstütze 1q. ist ein nach jeder Schl'eifsteingröße einstellbarer Körperstützpunkt geschaffen, der zugleich beim Antreiben des Schleifsteins einen Teil des Körpergewichtes aufnimmt.On the frame i a grindstone disk 3 underpinned by a pull-out water tank 2 is rotatably mounted, the shaft and cranks of which are connected to a lever 7 mounted on an axis 6 in the form of a horizontal bar as a result of handlebars and cardanic joints 5. Two freely oscillating levers i i, which are attached to the frame i by means of joints 8 and carry individual pedals 9, io on the other, lead through the lever 7. which are lifted automatically by tension springs i2. Arranged above the grinding stone disk 3 is an armrest 14, which can be changed by means of reversible bolts 13 and can be vertically displaced and locked. The same in the direction of arrow A of the lever 7 is swung balance-beam-like manner in Pf eilr ichtung B and q so through the transfer of the linkage by the pedals 9, io and changing up and down. turned the grindstone. Due to the arrangement of the adjustable armrest 1q. a body support point is created which can be adjusted according to each whetstone size and which at the same time absorbs part of the body weight when the whetstone is driven.
