Die Büchse 88 ist an die eine Ader 89 eines Anschlusskabels 90 angeschlossen, welches in den Schalen 80 durch ein Zugentlastungselement 91 gehalten ist. Die andere Ader 92 ist über einen Kippschalter 93 an eine weitere, seitlich versetzte, achsparallele Büchse 94 angeschlossen (Figur 4), welche in der einen Schale 80 gehalten ist. In der Büchse 94 ist der zweite, federbelastete Kontaktstift 95 verschiebbar. Die Stirnfläche des Stiftes 95 ist gegen die Stirnfläche des Flansches 73 angepresst. Damit ist der Heizdraht 20 mit beiden Enden über den Schalter 93 an die beiden Adern 89, 92 des Kabels 90 unabhängig von der Drehstellung des Griffs 1 oder Schwenkstellung des Halters 3 verbunden.A spring-loaded is located against the rear end face of the contact pin 25 Contact bolt 87 on. The pin 87 is in one Bushing 88, which is inserted into a shell 80, coaxial, insulating sleeve 96 is inserted. The rifle 88 is connected to one core 89 of a connecting cable 90, which is held in the shells 80 by a strain relief element 91 is. The other wire 92 is on via a toggle switch 93 a further, laterally offset, axially parallel sleeve 94 is connected (Figure 4), which is held in one shell 80. The second, spring-loaded contact pin 95 is in the bush 94 displaceable. The end face of the pin 95 is against the End face of the flange 73 pressed. This is the heating wire 20 with both ends via the switch 93 to the two wires 89, 92 of the cable 90 regardless of the rotational position of the handle 1 or pivoted position of the holder 3 connected.

Im Betrieb wird das beschriebene Gerät zum Beispiel wie folgt verwendet: Soll ein überstehender Rand der an der Mauer 58 befestigten Isolierschaumplatte 59 bündig mit dem Mauerende 98 abgeschnitten werden, wird zunächst die Schiene 4 so an die Platte 59 aufgelegt, dass die Richtkante 60 mit dem Ende 98 fluchtet. Hierauf werden die beiden Steckbleche 65 in die Platte 59 eingesteckt, womit die Schiene 4 fixiert ist. Die Leiste 53 wird in die Nut 63 eingesetzt, der Schalter 93 eingeschaltet und der Griff 1 gegen die Mauer 58 geschwenkt, bis die Gleitfläche 50 auf der Schiene 4 aufliegt. Nun wird das Gerät 1 bis 3 entlang der Schiene 4 verschoben, so dass der überstehende Rand der Platte 59 abgeschnitten wird. Wenn man sich einer konkaven Mauerkante nähert, wird der Kopf 37 hochgezogen und der Halter 3 im entsprechenden Sinne verschwenkt, so dass mit dem Draht 20 bis in die Mauerkante gefahren werden kann. Bei senkrechten Schnitten ist es vorteilhaft, den Griffteil 86 durch Zurückziehen des Schiebers 84 in die für die Arbeit bequemste Lage zu drehen und dort zu arretieren. Durch Verschwenken des Teils 33 sind Gerungsschnitte in einem wählbaren Winkel möglich.In operation, the device described is, for example, as follows used: Should a protruding edge of the attached to the wall 58 Insulating foam plate 59 cut flush with the end of the wall 98 first, the rail 4 is so on the plate 59 placed that the alignment edge 60 is aligned with the end 98. The two plug-in plates 65 are then inserted into the plate 59, with which the rail 4 is fixed. The bar 53 is in the groove 63 inserted, the switch 93 turned on and the Handle 1 pivoted against wall 58 until sliding surface 50 rests on the rail 4. Now the device 1 to 3 is along the rail 4 shifted so that the protruding edge of the Plate 59 is cut off. If you look at a concave wall edge approaches, the head 37 is raised and the holder 3 in corresponding senses pivoted so that with the wire 20 to can be driven into the edge of the wall. With vertical cuts it is advantageous to retract the handle portion 86 Slide 84 in the most convenient position for work and to lock there. By pivoting the part 33 are clenching cuts possible at a selectable angle.

Vorzugsweise wird ein Satz unterschiedlicher Halter 3 mit unterschiedlicher Länge des Bügels 14 und allenfalls unterschiedlichem Abstand des Bügelsteges vom Draht 20 bereitgestellt, um das Gerät unterschiedlichen Platzverhältnissen und Plattendicken anzupassen. Weil diese Halter 3 relativ einfach aufgebaut sind, kann damit ein sehr vielseitiges Gerät bereitgestellt werden. Das Gerät ist sehr einfach in der Handhabung. Es kann auch ohne die Führungsschiene 4 und das Führungselement 2 verwendet werden, indem ein zusätzliches Steckteil entsprechend dem Teil 33 bereitgestellt wird, welches jedoch einfacher ausgebildet ist, zum Beispiel zylindrisch und ohne den Exzenter 54 und Teile 34, 36, 37 und die zugehörige Feder. Es kann jedoch auch ein Halter 3 eingesetzt werden, der die gefederte Hülse 39 selbst enthält. Alternativ kann der Federmechanismus für den Bajonettverschluss auch im Kopf 70 eingebaut werden. Wenn die gefederte Hülse 39 zum Beispiel rechts des rechten Stirnendes des Schaftes 11 im Kopf 70 verschiebbar geführt ist und sich das Stirnende des Schaftes 11 gegen den Flansch entsprechend dem Flansch 40 abstützt, ist für die Freihandbedienung kein Übergangsstück erforderlich. Die Schnellkupplung zwischen Halter 3 und Griff 1 kann auch anders als ein Bajonettverschluss ausgebildet werden, zum Beispiel als Steckverbindung mit einem lösbaren Schnappelement.Preferably, a set of different holders 3 with different ones Length of the bracket 14 and possibly different Distance of the strap web from the wire 20 provided to the Adapt device to different space conditions and plate thicknesses. Because these holders 3 are relatively simple, can be used to provide a very versatile device. The device is very easy to use. It can also be done without the guide rail 4 and the guide element 2 are used, by an additional plug-in part corresponding to part 33 is provided, which is, however, made simpler, for example cylindrical and without the eccentric 54 and parts 34, 36, 37 and the associated spring. However, it can also be a holder 3 are used, which contains the spring-loaded sleeve 39 itself. Alternatively, the spring mechanism for the bayonet lock can also be installed in the head 70. If the spring-loaded sleeve 39 for example to the right of the right front end of the shaft 11 in Head 70 is slidably guided and the front of the Supports shaft 11 against the flange corresponding to flange 40, no transition piece is required for hands-free operation. The quick coupling between holder 3 and handle 1 can also be designed differently than a bayonet catch, for Example as a plug connection with a detachable snap element.

Der Draht 20 braucht nicht unbedingt gestreckt zu sein, sondern kann auch bogenförmig verlaufen, um zum Beispiel aus der Grossfläche der Platte 59 eine Struktur auszuschneiden. Der Halter 3 ist in diesem Fall entsprechend anders ausgebildet. Für die künstlerische Bearbeitung von Styroporblöcken können auch Halter 3 mit löffelförmigen Heizelementen eingesetzt werden. Das beschriebene Gerät ist deshalb sehr vielseitig in der Anwendung. The wire 20 need not necessarily be stretched, but rather can also run in an arc, for example from the large area cut out a structure of the plate 59. The holder 3 is designed differently in this case. For the Artistic processing of polystyrene blocks can also be made by holders 3 can be used with spoon-shaped heating elements. The described The device is therefore very versatile in use.

Das beschriebene Führungselement 2 mit der Führungsschiene 4 kann auch vorteilhaft für Geräte angewendet werden, in welchen der Halter 3 nicht austauschbar lösbar mit dem Griff 1 verbunden, sondern das Heizelement 20 direkt am Griff angebaut ist. Solche Geräte sind allerdings weniger vielseitig. Der Griff 1 braucht nicht abgekröpft zu sein, sondern kann auch kugelförmig ausgebildet werden. In diesem Fall entfällt der Schwenkmechanismus mit den Teilen 71 und 81-85. Der elektrische Anschluss des Heizdrahtes wird entsprechend vereinfacht. Bei fest am Halter 3 angebautem Griff 1 ist es jedoch vorteilhaft, wenn der Halter 3 samt Griff 1 austauschbar lösbar mit dem Führungselement 2 verbunden ist.The described guide element 2 with the guide rail 4 can also be used advantageously for devices in which the holder 3 is non-interchangeably detachably connected to the handle 1, but the heating element 20 is mounted directly on the handle. However, such devices are less versatile. The handle 1 does not need to be bent, but can also be spherical be formed. In this case, the swivel mechanism is omitted with parts 71 and 81-85. The electrical connection of the Heating wire is simplified accordingly. When firmly on the holder 3 attached handle 1, however, it is advantageous if the holder 3rd including the handle 1 interchangeably detachably connected to the guide element 2 is.

Statt des Heizdrahtes 20 kann unter Umständen auch ein anderes Schneidelement eingesetzt werden, zum Beispiel ein Lasergerät.Instead of the heating wire 20, another can also be used under certain circumstances Cutting element can be used, for example a laser device.
