Abstract

The electric hand drill is of the usual form with a body, handle, switch drill bit and chuck (6). A small electric bulb (14) is fitted in a holder (11) in a housing (8). The housing (8) is provided with a reflector (12) and a lens (13). Two contact pins (15) which project from the lower surface of the holder (8) are inserted into sockets in the housing (2). The sockets are electrically connected to the drill switch (4) so that the light is switched on with the drill. The light is so positioned that it shines on the drill bit (5) and illuminates the area around the hole being drilled. An additional switch in parallel to the drill switch (4) may also be provided.

Description

Beleuchtungsvorrichtung für elektrische Handbohrmaschinen Die Erfindung betrifft eine Beleuchtungsvorrichtung an elektrisehen Handbohrmaschinen. Bei elektrischen Handbohrmaschinen wird es als sehr nachteilig angesehen, dass eine Beleuchtung an der Ansetzstelle der Bohrspindel oder an der ganzen Bohrstelle fehlt. Da das genaue Ansetzen der Bohrspindel an der Bohrstelle erforderlich ist, ist es häufig notwendig, dass eine zweite Arbeitskraft die Bohrstelle mit einer Hilfsbeleuchtung beleuchten muss, zumal der Bedienungsnann für die Bohrmaschine fUr eine zusätzliche Beleuchtungsvorrichtung keine Hand frei hat. Lighting device for electric hand drills The invention relates to a lighting device on electric hand drills. With electrical Hand drills it is considered very disadvantageous to have lighting on the attachment point of the drilling spindle or the entire drilling point is missing. Since the exact It is necessary to position the drilling spindle at the drilling site, it is often necessary to that a second worker illuminates the drilling site with auxiliary lighting must, especially since the operator for the drill for an additional lighting device has no hand free.

Erfindungsgemäss wird diesem Ubelstand dadurch abgeholfen, dass eine Beleuchtungsvorrichtung mit Glühbirnenhalter oder Gehäuse, Glilhbirne, Reflektor und Schalter unter Benutzung der Stromquelle oder der Stromzuführung der Bohrmaschine in derem Gehäuse oder an dem Gehäuse derart angebracht ist, dass der Lichtkegel auf die Bohrstelle oder auf die Ansetzstelle der Bohrspindel gerichtet ist.According to the invention, this disadvantage is remedied in that a Lighting device with bulb holder or housing, incandescent bulb, reflector and switches using the power source or the power supply of the drill is mounted in the housing or on the housing in such a way that the light cone is directed to the drilling site or to the attachment point of the drilling spindle.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung an einer elktrischen Handbohrmaschine schematisch dargestellt. Es zeigt: Fig. 1 den vorderen Teil einer elktrischen Handbohrmaschine mit auf derem vorderen Teil angebauter Beleuchtungsvorrichtung in Seitenansicht, Fig. 2 eine elktrische Handbohrmaschine mit Bohrspindel und in derem Gehäuse eingebauter Beleuchtungsvorrichtung, in Seitenansicht, mit aufgebrochnem, die Beleuchtungsvorrichtung enthaltenen Teil des Gehäuses.In the drawing is an embodiment of the subject matter of Invention shown schematically on an electric hand drill. It shows: Fig. 1 shows the front part of an electric hand drill with on the front Part of the built-on lighting device in side view, FIG. 2 shows an electric Hand drill with drill spindle and lighting device built into its housing, in side view, with the part containing the lighting device broken open of the housing.

In Fig. 1 ist 1 eine elektrische Handbohrmaschine mit Gehäuse 2, Handgriff 3, Schalter 4 für die Stromzufuhr zum Bohrmaschinenmotor, 5 die Bohrspindel und 6 die Einspanneinrichtung für die Bohrspindel 5. Auf dem vorderen Teil des Bohrmaschinengehäuses 2 ist auf einer Tragplatte 7 ein Gehäuse 8 für eine Beleuchtungsvorrichtung 9 mit Stromzufuhrsteckern 10, GlUhbirnenfassung 11, Reflektor 12, Abdecklinsenglas 13 und GlUhbirne 14 angeordnet.In Fig. 1, 1 is an electric hand drill with housing 2, handle 3, switch 4 for the power supply to the drill motor, 5 the drill spindle and 6 the clamping device for the drilling spindle 5. On the front part of the drilling machine housing 2, a housing 8 for a lighting device 9 is provided on a support plate 7 Power supply plugs 10, light bulb socket 11, reflector 12, cover lens glass 13 and light bulb 14 arranged.

Die Tragplatte 7 kann mittels Gewindeschrauben am Bohrmaschinengehäuse 2 befestigt werden, oder mit der Beleuchtungseinrichtung durch die Steckerstifte 10, welche in entsprechenden Stromanschlu sbuchsen 15 des Bohrmaschinengehäuses 2 eingesteckt werden.The support plate 7 can be attached to the drill housing by means of threaded screws 2, or with the lighting device through the connector pins 10, which in corresponding Stromanschlu sbuchsen 15 of the drill housing 2 can be plugged in.

Die Steckerbuchsen 15 haben im Inneren des Bohrmaschinengehäuses 2 einen isolierten Anschluss an die Stromzufuhr fUr den Bohrmaschinenmotor der Bohrmaschine, so dass die Glühbirne 14 aufleuchtet, sobald die Handbohrmaschine eingeschaltet wird.The plug sockets 15 have 2 inside the drilling machine housing an isolated connection to the power supply for the drill motor of the drill, so that the light bulb 14 lights up as soon as the hand drill is switched on will.

Die Beleuchtungsvorrichtung 9 kann auch über die Stromzufuhr zum Bohrmaschinenmotor parallel zum Schalter 4 mit besonderem äusserem Schalter s Pnagerden. -So Fig, 2 ist die Beleuchtungsvorrichtung 9 mit Gehäuse 8, Glühbirnenfassung 11, Reflektor 12, Abdecklinsenglas 13, Glühlampe 14 in das Gehäuse der Bohrmaschine eingebaut und wieder Uber Stromzuführungsleitung über den Schalter 4 der Bohrmaschine 1 oder über besonderen Schalter verbunden.The lighting device 9 can also be connected to the power supply to the drill motor parallel to switch 4 with a special external switch s pnagerden. -So Fig, 2 is the lighting device 9 with housing 8, bulb holder 11, reflector 12, cover lens glass 13, incandescent lamp 14 built into the housing of the drill and again via the power supply line via the switch 4 of the drill 1 or connected via special switch.

Bei nachträglichem Anbau der Beleuchtungsvorrichtung, kann deren Stromzufuhr auchaussen über ein Kabel mit Zwischensteck r oder dergl. mit der Stromzuführungsleitung der Bohrmaschine in Verbindung gebracht werden.If the lighting device is retrofitted, its power supply also on the outside via a cable with adapter plug r or the like with the power supply line the drill.

Die dargestellten und beschriebenen Ausführungsbeispiele können in Anpassung an deren Verwendungszweck in den Einzelheiten zahlreiche Abänderungen erfahren, ohne dass der Bereich der Erfindung verlassen wird.The illustrated and described exemplary embodiments can be found in Adaptation to their intended use in the details numerous changes without departing from the scope of the invention.
