Description

Die Erfindung betrifft einen Leitungssucher zum Orten von Leitungen in einer Wand, insbesondere zum Orten von Wasserleitungen, elektrischen Leitungen oder dgl., nach dem Oberbegriff des Anspruches 1.The invention relates to a line finder for locating Pipes in a wall, especially for locating water pipes electrical lines or the like, according to the generic term of claim 1.

Derartige Leitungssucher sind an sich bekannt und dienen dem Absuchen einer Wand nach Leitungen, bevor an vorgesehenen Stellen Löcher mit einer Bohrmaschine oder einem Bohrhammer oder Nuten mit einem Nutfräser gesetzt werden. Diese Leitungssucher haben sich in der Praxis bewährt und sind insbesondere dort unentbehrlich, wo der Verlauf oder die Anordnung von Leitungen unbekannt ist.Such line finders are known per se and serve searching a wall for wires before provided on Make holes with a drill or one Drill hammer or grooves can be set with a groove cutter. These line searchers have proven themselves in practice and are particularly indispensable where the course or the arrangement of lines is unknown.

Der Leitungssucher ist ein von der Bohrmaschine getrenntes Gerät und muß zusätzlich zur Bohrmaschine vor Ort zur Verfügung gehalten werden. In der Praxis hat sich gezeigt, daß der Leitungssucher oft vergessen wird, so daß dann auf Verdacht die notwendigen Bohrungen in einer Wand vorgenommen werden. Dies kann zu erheblichen Schäden führen, wenn eine Wasserleitung oder eine elektrische Leitung angebohrt wird. Meist muß dann die Wand in einem großen Bereich aufgestemmt werden, um den Schaden zu beheben. The line finder is separate from the drill Device and must be available on site in addition to the drill being held. In practice it has been shown that the line finder is often forgotten, so that then suspicion made the necessary holes in a wall become. This can cause significant damage if one Water pipe or an electrical line is drilled. Most of the time, the wall has to be pried open in a large area to fix the damage.

Zum Schutz des Benutzers einer Bohrmaschine vor elektrischem Schlag ist auch schon vorgeschlagen worden, bei elektrischem Kontakt der Bohrspitze mit einer stromführenden Leitung eine im Motorgehäuse der Bohrmaschine angeordnete Schutzschaltung zu aktivieren, die ein Abschalten der Bohrmaschine bewirkt. Eine derartige Anordnung schützt aber nicht vor Schäden an den in der Wand verlegten Leitungen.To protect the user from a drill electric shock has also been suggested with electrical contact of the drill tip with a live one Line arranged in the motor housing of the drill Activate protection circuit that a shutdown the drilling machine. Such an arrangement protects but not against damage to the cables laid in the wall.

Der Erfindung liegt die Aufgabe zugrunde, einen Leitungssucher der gattungsgemäßen Art derart zu gestalten, daß er jederzeit vor Ort verfügbar ist und vom Benutzer vorzugsweise auch während des Betriebes der Bohrmaschine verwendet werden kann.The invention has for its object a line finder to design the generic type in such a way that it is always available on site and preferred by the user also used during the operation of the drilling machine can be.

Die Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruches 1 gelöst.The task is inventively according to the characteristic Features of claim 1 solved.

Die Integration des Leitungssuchers in dem dem Werkzeug benachbarten vorderen Handgriff einer Werkzeugmaschine stellt sicher, daß - bevor z.B. eine Bohrung oder Nut gesetzt wird - mittels des Leitungssuchers im Bereich des beabsichtigten Bohrloches verlaufende Leitungen erkannt werden. Der Bohrvorgang wird daher bei Ansprechen des im Handgriff der Bohrmaschine integrierten Leitungssuchers gar nicht erst begonnen, so daß sowohl Schäden an elektrischen Leitungen als auch Schäden der Wand vermieden sind.The integration of the line finder in the one adjacent to the tool front handle of a machine tool sure that - before e.g. a hole or groove set is - by means of the line finder in the area of the intended Lines running down the borehole are recognized. The drilling process is therefore in response to the in the handle the drill integrated line finder not at all only started, so that both damage to electrical Lines and damage to the wall are avoided.

Bevorzugt wird zur Spannungsversorgung des Leitungssuchers eine im Handgriff angeordnete Batterie oder ein Akku-Pack verwendet; es kann auch zweckmäßig sein, eine Verbindung zum Spannungsnetz der Bohrmaschine vorzusehen. Preference is given to supplying power to the line finder a battery or a battery pack arranged in the handle used; it may also be appropriate to connect to be provided for the power supply of the drilling machine.

Die Sensorik des Leitungssuchers liegt vorteilhaft in einem nasenförmigen Gehäusevorsprung des freien Endes des Handgriffes, so daß durch den nasenförmigen Gehäusevorsprung ein geringer Abstand zur Wand gegeben ist, was die Funktionssicherheit erhöht.The sensor technology of the line finder advantageously lies in one nose-shaped housing projection of the free end of the handle, so that through the nose-shaped housing projection a small distance from the wall is what the Functional reliability increased.

In bevorzugter Ausgestaltung der Erfindung liegen die Sensorik, die Elektronik und die Spannungsquelle innerhalb eines Innengehäuses des Handgriffes, welches von einem äußeren Griffgehäuse umgeben ist. Dabei ist das Innengehäuse zusammen mit dem Leitungssucher zweckmäßig als axial in das Griffgehäuse einschiebbares Modul ausgebildet, welches bevorzugt auch außerhalb des Griffgehäuses betriebsfertig ist und eingesetzt werden kann.In a preferred embodiment of the invention, the sensors, the electronics and the voltage source inside of an inner housing of the handle, which by a outer handle housing is surrounded. Here is the inner case together with the line finder useful as module axially insertable into the handle housing, which preferably also ready for use outside the handle housing is and can be used.

Der mit einem integrierten Leitungssucher versehene Handgriff 1 wird nahe dem Spannfutter 31 einer Bohrmaschine 32 (Fig. 1) an einem zylindrischen Befestigungsabschnitt 33 maschinenfest fixiert.The handle with an integrated line finder 1 is near the chuck 31 of a drill 32 (Fig. 1) on a cylindrical fastening portion 33 machine-fixed.

Der Handgriff 1 besteht im wesentlichen aus einem etwa zylinderförmigen, vorteilhaft im Schnitt elliptischen Griffgehäuse 7 (Fig. 5, 6), welches an einem Ende 3 eine im Durchmesser erweiterte Ringschulter 8 zeigt. Die Ringschulter 8 trennt den Handgriff 1 von einem Geräteanschluß 9, mit dem der Handgriff 1 an dem Befestigungsabschnitt 33 der Bohrmaschine 32 eines Bohrhammers oder dgl. montiert wird. Der Geräteanschluß 9 besteht im wesentlichen aus einer zylindrischen, geschlitzten Schelle 2, die über einen Sockel 10 starr mit dem Ende 3 des Handgriffes 1 verbunden ist. Der Klemmschlitz der Schelle 2 wird von einer Klemmschraube 5 überbrückt, welche in den Sockel 10 eingreift. Mittels der Klemmschraube 5 wird die Schelle 2 auf dem zylindrischen Befestigungsabschnitt 33 in einer gewünschten Lage kraftschlüssig festgelegt.The handle 1 consists essentially of an approximately cylindrical, advantageous in section elliptical handle housing 7 (Fig. 5, 6), which at one end 3 in Diameter expanded ring shoulder 8 shows. The ring shoulder 8 separates the handle 1 from a device connection 9, with which the handle 1 on the mounting portion 33 of the Drill 32 of a rotary hammer or the like. Is mounted. The device connection 9 consists essentially of a cylindrical, slotted clamp 2 over a base 10 is rigidly connected to the end 3 of the handle 1. The clamp slot of clamp 2 is a clamp screw 5 bridges, which engages in the base 10. Means the clamping screw 5, the clamp 2 on the cylindrical Attachment section 33 in a desired Position determined non-positively.

Der zylindrische Mantel 4 der Schelle 2 hat eine Längsmittelachse 6, welche bei an der Bohrmaschine, dem Bohrhammer oder dgl. Werkzeugmaschine montiertem Handgriff 1 gleichachsig mit der Drehachse 34 des Werkzeuges ist.The cylindrical jacket 4 of the clamp 2 has a longitudinal central axis 6, which at the drill, the hammer drill or the like. Machine tool-mounted handle 1 is coaxial with the axis of rotation 34 of the tool.

Der Sockel 10 hat etwa rechteckförmige Gestalt und weist - wie die Fig. 2 und 4 zeigen - in Richtung der Längsmittelachse 6 eine axiale Erstreckung auf, die der Breite der Schelle 2 entspricht. Aus Fig. 3 ist zu entnehmen, daß der Sockel 10 eine Breite aufweist, die geringfügig kleiner als der Außendurchmesser der Schelle 2 ist. The base 10 has an approximately rectangular shape and has - As shown in FIGS. 2 and 4 - in the direction of the longitudinal central axis 6 an axial extent that the width corresponds to the clamp 2. From Fig. 3 it can be seen that the base 10 has a width that is slightly smaller than the outside diameter of the clamp 2.

Das Griffgehäuse 1 hat ausweislich der Fig. 5 und 6 einen ovalen Querschnitt, wobei die größere Achse A des Querschnittes in gleicher Richtung wie die Längsmittelachse 6 der Schelle 2 orientiert ist und parallel zu dieser Längsmittelachse 6 liegt. Ausweislich Fig. 4 ist das Griffgehäuse 7 hohl ausgebildet und an seinem der Manschette 2 abgewandten Ende 11 offen. Das Griffgehäuse 7 weist - wie die Fig. 2 und 3 zeigen - eine bevorzugt nach vorne gewandte Riffelung 12 zur Erhöhung der Griffigkeit auf. Es kann zweckmäßig sein, die Riffelung 12 über den gesamten Umfang des Griffgehäuses 7 vorzusehen.According to FIGS. 5 and 6, the handle housing 1 has one oval cross-section, the major axis A of the cross-section in the same direction as the longitudinal central axis 6 the clamp 2 is oriented and parallel to this longitudinal central axis 6 lies. According to Fig. 4 is the handle housing 7 hollow and on its facing away from the cuff 2 Open late 11. The handle housing 7 has - like that 2 and 3 show - a preferably facing forward Grooving 12 to increase grip. It can be appropriate, the corrugation 12 over the entire circumference to provide the handle housing 7.

In das Griffgehäuse 7 ist ein im Querschnitt etwa rechteckiges Innengehäuse 13 axial einzuschieben, wobei das Innengehäuse 13 mit seinen vorzugsweise gerundeten Längskanten 14 an der Wandung des Griffgehäuses 7 anliegt und dadurch im wesentlichen spielfrei im Innenraum 15 des Griffgehäuses 7 gehalten ist. Das Innengehäuse 13 ragt mit einem nasenförmig gestalteten Ende 16 aus dem Griffgehäuse 7 heraus, wobei die offene Stirnseite des Endes 11 auf einer Ringschulter 17 des nasenförmigen Endes 16 aufliegt. Dadurch ist der Innenraum 15 des Griffgehäuses 7 weitgehend staub- und flüssigkeitsdicht verschlossen.In the handle housing 7 is an approximately rectangular in cross section Insert the inner housing 13 axially, the Inner housing 13 with its preferably rounded longitudinal edges 14 rests against the wall of the handle housing 7 and thereby essentially free of play in the interior 15 of the Handle housing 7 is held. The inner housing 13 also projects a nose-shaped end 16 from the handle housing 7 out, with the open end of the end 11 on an annular shoulder 17 of the nose-shaped end 16 rests. As a result, the interior 15 of the handle housing 7 is largely sealed dust and liquid tight.

Wie aus den Schnittdarstellungen Fig. 5 und 6 zu ersehen, entspricht die Außenkontur des nasenförmigen Endes 16 bis auf die Nasen 18 im Querschnitt der elliptischen Kontur des Griffgehäuses 7; die Nase 18 steht in Richtung der großen Längsachse A über den mit Riffelung 12 versehenen vorderen Mantelabschnitt 19 des Griffgehäuses 7 über, so daß die Nase 18 im wesentlichen in Richtung der Längsmittelachse 6 der Schelle 2 in Richtung zum Spannfutter 31 zeigt. As can be seen from the sectional views of FIGS. 5 and 6, corresponds to the outer contour of the nose-shaped end 16 to on the lugs 18 in cross section of the elliptical contour of the Handle housing 7; the nose 18 faces the large one Longitudinal axis A over the front with corrugation 12 Sheath section 19 of the handle housing 7 so that the nose 18 essentially in the direction of the longitudinal central axis 6 the clamp 2 shows in the direction of the chuck 31.

Das Innengehäuse 13 dient der Aufnahme der Bauteile eines Leitungssuchers 20, mit dem Leitungen, insbesondere Wasserleitungen, elektrische Leitungen oder dgl., in einer Wand geortet werden können.The inner housing 13 serves to hold the components of a Line finder 20 with which lines, in particular water lines, electrical lines or the like, in a wall can be located.

Der Leitungssucher 20 besteht im wesentlichen aus einer Sensorik 21 aus einem oder mehreren Sensoren, die in dem nasenförmigen Ende 16 des Innengehäuses 13 angeordnet ist. Die Sensorik 21 liegt dabei in der in Richtung auf die Wand orientierte Nase 18, wodurch ein ausreichend geringer Abstand zur Wand gegeben ist, was eine ordnungsgemäße Funktion des Leitungssuchers sicherstellt. Die in der Nase 18 liegende Sensorik 21 des Leitungssuchers 20 ist mit einer die Sensorsignale auswertenden Elektronik 22 verbunden, welche zweckmäßig benachbart zum Sensor 11 im Bereich des offenen Endes 11 des Griffgehäuses 7 im Innengehäuse 13 liegt. Die Elektronik 22 steuert eine Anzeige, die im gezeigten Ausführungsbeispiel eine akustische Anzeige in Form eines Summers 23 sein kann. Zweckmäßig ist auch eine optische Anzeige an geeigneter Stelle.The line finder 20 consists essentially of a Sensor system 21 from one or more sensors, which in the nose-shaped end 16 of the inner housing 13 is arranged. The sensor system 21 lies in the direction of the wall oriented nose 18, creating a sufficiently small distance given to the wall what is a proper Ensures the function of the line finder. The one in the nose 18 lying sensor system 21 of the line finder 20 is with connected to electronics 22 evaluating the sensor signals, which expediently adjacent to the sensor 11 in the area of the open end 11 of the handle housing 7 in the inner housing 13 lies. The electronics 22 controls a display that is in the shown embodiment an acoustic display in May be in the form of a buzzer 23. One is also useful visual display at a suitable point.

Das Innengehäuse 13 ist an seinem inneren Ende 24 zur Aufnahme einer Spannungsquelle 25 offen, die im gezeigten Ausführungsbeispiel eine Batterie in Form eines 9-Volt-Blocks oder ein Akku-Pack sein kann. Die Batterie bzw. der Akku-Pack dient der Spannungsversorgung der Elektronik 22 sowie der Anzeige in Form des Summers 23.The inner housing 13 is at its inner end 24 for receiving a voltage source 25 open in the embodiment shown a battery in the form of a 9 volt block or can be a battery pack. The battery or the battery pack serves to supply power to the electronics 22 and the display in the form of the buzzer 23.

Es kann zweckmäßig sein, die Batterie 25 mittels einer Feder 27 in einer Außerbetriebsstellung zu halten, in der ihre Kontakte 28 mit Abstand zu den Kontakten 26 der Elektronik 22 liegen. Beim Einschieben des modulartigen Innengehäuses 13 in das Griffgehäuse 7 gelangt die Batterie auf den Boden 29 des Griffgehäuses unter Zwischenschaltung einer Feder 40 zur Anlage und wird gegen die Kraft der schwächeren Feder 27 in das Innengehäuse 13 eingeschoben, bis ihre Kontakte 28 auf den Kontakten 26 zur Anlage kommen. Der elektrische Stromkreis der Elektronik 22 ist geschlossen; die Elektronik ist betriebsbereit.It may be appropriate to use the battery 25 by means of a spring 27 to keep in a non-operating position, in the their contacts 28 at a distance from the contacts 26 of the Electronics 22 lie. When inserting the modular Inner battery 13 enters the handle housing 7, the battery to the bottom 29 of the handle housing with interposition a spring 40 to the system and is against the force of weaker spring 27 inserted into the inner housing 13, until their contacts 28 come into contact with the contacts 26. The electrical circuit of the electronics 22 is closed; the electronics are ready for operation.

Zweckmäßig ist das innere Ende 24 mit einem Deckel 39 verschlossen, so daß das Innengehäuse 13 als vom Handgriff 1 getrenntes Modul als Leitungssucher genutzt werden kann.The inner end 24 is expediently closed with a cover 39, so that the inner housing 13 as from the handle 1st separate module can be used as a line finder.

Da über den Handgriff 1 oft große Kräfte in das Werkzeug eingeleitet werden, ist es zweckmäßig, das Griffgehäuse 7 mit dem Sockel 10 und der Manschette 2 einteilig aus widerstandsfähigem Kunststoff, Metall oder einer Leichtmetallegierung zu gestalten. Bei einem Metallgehäuse ist zudem sichergestellt, daß die im Griffgehäuse 7 liegende Elektronik gegen Störstrahlungen geschützt liegt. Das Innengehäuse 13 hingegen ist zweckmäßig aus Kunststoff gestaltet, insbesondere das nasenförmige Ende 16, da Kunststoff die Wirkung der Sensoren 21 nicht beeinträchtigt.Because of the handle 1 often large forces in the tool initiated, it is appropriate to the handle housing 7th with the base 10 and the sleeve 2 in one piece from resistant Plastic, metal or a light metal alloy to design. With a metal case also ensured that the lying in the handle housing 7 Electronics is protected against interference. The inner case 13, on the other hand, is expediently made of plastic, in particular the nose-shaped end 16, since plastic the effect of the sensors 21 is not impaired.

Das Innengehäuse 13 ist zusammen mit dem Leitungssucher 20, d.h. der Sensorik 21, der Elektronik 22, der akustischen Anzeige in Form eines Summers 23 und der Spannungsquelle 25, als Einschubmodul gestaltet.
