PATENTANSPRÜCHE 1. Zusatzeinrichtung für eine Handbohrmaschine, dadurch gekennzeichnet, dass sie zum richtungsgenauen Führen der Bohrmaschine mit zwei als Libellen (3, 4) ausgebildeten Wasserwaagen ausgerüstet ist. PATENT CLAIMS 1. Additional device for a hand drill, characterized in that it is equipped with two spirit levels designed as vials (3, 4) for guiding the drill accurately.
2. Zusatzeinrichtung nach Patentanspruch 1, dadurch gekennzeichnet, dass die Anzeigeebenen der beiden Libellen senkrecht aufeinander stehen, derart, dass sie ein genaues waagrechtes bzw. senkrechtes Führen der Bohrmaschine ermöglichen. 2. Additional device according to claim 1, characterized in that the display planes of the two dragonflies are perpendicular to each other, such that they enable precise horizontal or vertical guidance of the drilling machine.
3. Zusatzeinrichtung nach Patentanspruch 2, dadurch gekennzeichnet, dass die beiden Libellen an einem Klemmring (1) angeordnet sind, der zum Aufstecken auf die zylindrische Frontpartie eines Bohrmaschinengehäuses ausgebildet ist. 3. Additional device according to claim 2, characterized in that the two vials are arranged on a clamping ring (1) which is designed to be plugged onto the cylindrical front part of a drill housing.
4. Handbohrmaschine mit einer Zusatzeinrichtung nach Patentanspruch 2, dadurch gekennzeichnet, dass die beiden Libellen fest im Gehäuse der Bohrmaschine eingebaut sind. 4. Hand drill with an additional device according to claim 2, characterized in that the two vials are firmly installed in the housing of the drill.
Die erfindungsgemässe Zusatzeinrichtung soll es ermöglichen mit einer Handbohrmaschine eine vorgeschriebene Bohrrichtung, z.B. senkrecht zu einer vertikalen oder horizontalen Fläche, genau einzuhalten. The additional device according to the invention is intended to enable a prescribed drilling direction, e.g. perpendicular to a vertical or horizontal surface.
Bisher war stets die Geschicklichkeit des die Bohrmaschine Führenden massgebend, ob die Bohrlochachse genau senkrecht zu einer Wand, einem Boden oder einer Decke stand. So far, the skill of the operator of the drill has always been decisive, whether the borehole axis was exactly perpendicular to a wall, a floor or a ceiling.
Die Erfindung löst dieses Problem dadurch, dass zwei als Libellen ausgebildete Wasserwaagen fest oder lösbar an der Handbohrmaschine angeordnet werden. The invention solves this problem in that two spirit levels designed as vials are arranged fixedly or releasably on the hand drill.
Anhand der Zeichnung werden nachfolgend Ausführungsbeispiele der Erfindung näher erläutert. Exemplary embodiments of the invention are explained in more detail below with the aid of the drawing.
Die Figuren 1 und 2 zeigen einen Klemmring 1, der auf die zylindrische Frontpartie des Gehäuses einer Handbohrmaschine aufgesetzt und mittels einer Schraube 2 fixiert werden kann. Auf dem Ring 1 sind zwei Libellen 3, 4 angeordnet, deren Anzeigeebenen senkrecht aufeinander stehen. Wie aus Figur 3 klar ersichtlich, dient die Libelle 4 zum genauen horizontalen Führen der Maschine, wenn ein Loch in eine vertikale Wand gebohrt werden soll. Die Libelle 3 dient zum genauen vertikalen Führen der Maschine beim Bohren von Löchern in Böden oder Decken. Figures 1 and 2 show a clamping ring 1, which can be placed on the cylindrical front part of the housing of a hand drill and fixed by means of a screw 2. Two dragonflies 3, 4 are arranged on the ring 1, the display planes of which are perpendicular to one another. As can clearly be seen in FIG. 3, the level 4 serves to guide the machine precisely horizontally when a hole is to be drilled in a vertical wall. The level 3 is used to precisely guide the machine vertically when drilling holes in floors or ceilings.
Beim Ausführungsbeispiel nach Figur 4, das für relativ schwere Handbohrmaschinen bestimmt ist, ist der Ring nach den Figuren 1, 2 noch mit einem Handgriff 6 kombiniert. An einem Seitenarm des Ringes, der mit 5 bezeichnet ist, kann in an sich bekannter Weise ein Distanzstab 7 eingeschoben sein. In the embodiment according to FIG. 4, which is intended for relatively heavy hand drills, the ring according to FIGS. 1, 2 is still combined with a handle 6. On a side arm of the ring, which is denoted by 5, a spacer rod 7 can be inserted in a manner known per se.
Schliesslich ist in Figur 5 noch eine Ausführungsform dargestellt, bei der die beiden Libellen 3, 4 fest im Getriebegehäuse der Maschine eingebaut sind. Um das richtungsgenaue Bohren von Löchern auch unter einem anderen als einen rechten Winkel zu einer senkrechten oder waagrechten Fläche zu ermöglichen, könnte eine Libelle auch schwenkbar am Haltering bzw. am Gehäuse angebracht werden, wobei sie in jeder bezüglich einer Winkelskala eingestellten Lage fixiert werden könnte. Beim Bohren müsste dann die Maschinenachse gerade um diesen Winkel geneigt werden, damit die Libelle zum Einspielen kommt. Finally, FIG. 5 shows an embodiment in which the two vials 3, 4 are permanently installed in the gear housing of the machine. In order to enable the directional drilling of holes at a angle other than a right angle to a vertical or horizontal surface, a dragonfly could also be pivotally attached to the retaining ring or the housing, whereby it could be fixed in any position set with respect to an angle scale. When drilling, the machine axis would then have to be inclined at just this angle so that the dragonfly comes into play.
