Description

Die Erfindung bezieht sich auf eine transportable Vor­richtung zum Schneiden von Platten aus weichem Material mit Hilfe eines Schneidorgans und einer Grundplatte mit seitlichen Führungen, in denen ein Anpress-Schneidlineal auf- und abwärts bewegbar parallel zum Rand der Grund­platte geführt ist. Ist die zu schneidende Platte eine Kunststoff-Schaumplatte, kommt als Schneidorgan ein elek­trisch erhitzter Draht in Frage. Ist die Platte beispiels­weise aus Glaswolle, kann sie mit Hilfe eines entlang des Anpress-Schneidlineals geführten Messers geschnitten wer­den.
Aehnliche Vorrichtungen sind bekannt. Sie finden meist Verwendung auf dem Bau. Daher ist die Vorrichtung trans­portabel ausgebildet und die Energie zum Aufheizen des Schneiddrahtes wird meist aus einer Batterie bezogen. Es kommt dabei vor, dass nach dem Schneiden vergessen wird, den Strom abzuschalten. Dies hat den Nachteil, dass da­ durch die Batterie unnötig entladen wird und birgt zu dem die Gefahr in sich, dass man sich am heissen Draht ver­brennt. Durch Unachtsamkeit kann sogar ein Brand ent­stehen, wenn ein leicht brennbarer Gegenstand mit dem heissen Draht in Berührung kommt.The invention relates to a transportable device for cutting plates made of soft material with the aid of a cutting member and a base plate with lateral guides, in which a pressure-cutting ruler is guided to move up and down parallel to the edge of the base plate. If the plate to be cut is a plastic foam plate, an electrically heated wire can be used as the cutting element. If the plate is made of glass wool, for example, it can be cut with the help of a knife that runs along the pressure-cutting ruler.
Similar devices are known. They are mostly used in construction. The device is therefore designed to be transportable and the energy for heating the cutting wire is usually obtained from a battery. It happens that after cutting is forgotten to turn off the power. This has the disadvantage that there is unnecessarily discharged by the battery and also entails the risk of burning yourself on the hot wire. Carelessness can even cause a fire if an easily flammable object comes into contact with the hot wire.

Die Erfindung stellt sich zur Aufgabe diese Nachteile, wie sie bei der Schneidarbeit mit einem erhitzten Draht ent­stehen, zu beheben.The object of the invention is to remedy these disadvantages, such as those which arise during cutting work with a heated wire.

Die Erfindung löst diese Aufgabe mit einer Vorrichtung, die die im kennzeichnenden Teil des Patentanspruches 1 ge­nannten Merkmale aufweist. Die elektrisch leitenden Auf­lageleisten können dauernd an Spannung liegen, ohne dass dabei die Batterie entladen wird. Der Schneiddraht ist in einem separaten Bügel, ähnlich einer Spannsäge, gehalten. Nur zum Schneiden werden die nach unten gerichteten Arme des Bügels an die Auflageliesten gedrückt, so dass nur dann Strom durch den Schneiddraht fliesst und mit dem Draht geschnitten werden kann. Nach Beendigung eines Schnittes wird der Bügel mit dem Draht auf die Seite ge­legt und es fliesst kein Strom mehr.
In der beigefügten Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt und nachfolgend be­ schrieben.

  • Figur 1 zeigt die Vorrichtung in vereinfachter Dar­stellung;
  • Figur 2 einem Teil der Vorrichtung in Ansicht von oben in grösserem Masstab;
  • Figur 3 einen Vertikalschnitt der Vorrichtung in grösserem Masstab.
The invention solves this problem with a device having the features mentioned in the characterizing part of claim 1. The electrically conductive support strips can be permanently live without the battery being discharged. The cutting wire is held in a separate bracket, similar to a jig saw. The arms of the bracket, which are directed downwards, are pressed against the support members only for cutting, so that only then does current flow through the cutting wire and can be cut with the wire. After completing a cut, the wire is put on the side with the wire and no more current flows.
In the accompanying drawing an embodiment of the subject matter of the invention is shown and below be wrote.
  • Figure 1 shows the device in a simplified representation;
  • Figure 2 shows part of the device in a view from above on a larger scale;
  • Figure 3 is a vertical section of the device on a larger scale.

Figur 1 zeigt die Vorrichtung in perspektivischer Dar­stellung. Sie umfasst einen im unteren Teil der Zeichnung dargestellten Teil A mit einer Grundplatte und einen se­paraten Teil B mit dem in einem Bügel, spannsägeartig ge­spannten Schneiddraht.
Teil A umfasst eine Grundplatte 1, an dessen vorderen Rand zwei U-förmige Führungsschienen 2 angeordnet sind, die der Führung eines Anpress-Schneidlineals 3 dienen. Auf der Grundplatte ist eine Führungsschiene 4 für eine zu schnei­dende Platte befestigbar.
Vorne auf jeder Führung sind von den Führungsschienen 2 isolierte, im Querschnitt L-förmige Auflageleisten 5 ange­bracht. Durch die Grundplatte hindurchgeführte Anschluss­ leitungen 51 sind mit den Auflageleisten 5 verbunden. An den äusseren Enden sind Stecker 52 angebracht zum An­schluss an eine Stromquelle wie zum Beispiel eine Auto­batterie. An der Schmalseite der Grundplatte sind schieberartig herausziehbare Aufhängelaschen 11 ange­ordnet. Die Vorrichtung kann dann horizontal stehend oder an der Wand hängend gebraucht werden.
Unten an der Grundplatte 1 sind Anschläge 12 angeordnet, die auf die Schnittebene ausgerichtet sind.
Das Schneidorgan B besteht aus einem Bügel, an dem der Schneiddraht 6 in gespannter Lage gehalten ist. Der Bügel selber besteht aus einem Längsstab 7 aus elektrisch iso­lierendem Material und an den Enden des Stabes sind nach unten gerichtete Arme 8 angeordnet zwischen denen der Schneiddraht 6 gespannt ist. Die Arme 8 bestehen aus elek­trisch leitendem Material. Am linken Arm 8 ist der Schneiddraht 6 bei 81 bestigt. Am rechten Arm 8 ist er über einen Zapfen 82 umgelenkt und wird mittels einer Zugfeder 83 in gespanntem Zustand gehalten.Figure 1 shows the device in perspective. It comprises a part A shown in the lower part of the drawing with a base plate and a separate part B with the cutting wire clamped in a bracket like a saw.
Part A comprises a base plate 1, on the front edge of which two U-shaped guide rails 2 are arranged, which serve to guide a pressure-cutting ruler 3. A guide rail 4 for a plate to be cut can be fastened on the base plate.
On the front of each guide 2 support strips 5 with an L-shaped cross section are insulated from the guide rails. Connection led through the base plate Lines 51 are connected to the support strips 5. At the outer ends there are plugs 52 for connection to a power source such as a car battery. On the narrow side of the base plate slidable pull-out hangers 11 are arranged. The device can then be used standing horizontally or hanging on the wall.
At the bottom of the base plate 1 stops 12 are arranged, which are aligned with the cutting plane.
The cutting member B consists of a bracket on which the cutting wire 6 is held in a tensioned position. The bracket itself consists of a longitudinal rod 7 made of electrically insulating material and at the ends of the rod downward arms 8 are arranged between which the cutting wire 6 is stretched. The arms 8 are made of electrically conductive material. The cutting wire 6 is secured at 81 on the left arm 8. On the right arm 8 it is deflected by a pin 82 and is held in a tensioned state by means of a tension spring 83.

Die Figuren 2 und 3 zeigen Teile der Vorrichtung in grös­serem Masstab, in denen auch weitere Details ersichtlich sind. In dieser Zeichnung ist die Isolationsschicht 53 zwischen den Führungsschienen 2 und den Auflageleisten deutlich erkennbar. Auch die Grundplatte 1 ist an ihrem vorderen Rand mit einer Isolationsschicht 13 versehen, genauso wie der Anpress-Schneidlineal 3. Dieser weist an seiner Vorderseite einen Isolationsschicht 31 auf. Der Sinn dieser Isolationsschichten 31,13 ist klar, wenn man bedenkt, dass der Schneiddraht 6 sich beim Schneiden längs der strichpunktierten Linie nahe am Anpress-Schneidlineal und der Grundplatte vorbei geführt wird.
Der Längsstab 7 des Bügel B ragt bei 71 ein wenig über die Arme 8 hinaus. Diese Vorsprünge 71 des Längsstabes bilden einen Anschlag auf den oberen Enden 54 der im Querschnitt L-förmigen Auflageleisten, damit der Schneiddraht die Grundplatte nicht berührt.
In Figur 3 ist eine Schaumstoffplatte P zwischen der Grundplatte und dem Anpress-Schneidlineal gehalten, bereit um durch den erhitzten Schneiddraht zugeschnitten zu wer­den.
Beim Schneiden mit dem erhitzten Schneiddraht geht man wie folgt vor:

  • a) die zu schneidende Platte P soweit unter den Anpress-­Schneidlineal vorschieben wie abgeschnitten werden soll.
  • b) den Anpress-Schneidlineal auf die Platte drücken um sie in der gewünschten Lage zu halten.
  • c) den Bügel B mit dem Schneiddraht 6 mit seinen Armen an die Auflageleisten 5 drücken, damit Strom durch den Draht 6 fliesst und sich dieser erhitzt.
  • d) unter ständigem Andrücken an die Leisten 5, den Bügel abwärts führen und schneiden.
Figures 2 and 3 show parts of the device on a larger scale, in which further details can also be seen. In this drawing, the insulation layer 53 is between the guide rails 2 and the support strips clearly. The base plate 1 is also provided with an insulation layer 13 on its front edge, just like the pressure-cutting ruler 3. This has an insulation layer 31 on its front side. The meaning of these insulation layers 31, 13 is clear when one considers that the cutting wire 6 is guided past the pressure-cutting ruler and the base plate when cutting along the dash-dotted line.
The longitudinal bar 7 of the bracket B protrudes slightly beyond the arms 8 at 71. These projections 71 of the longitudinal bar form a stop on the upper ends 54 of the L-shaped support strips so that the cutting wire does not touch the base plate.
In Figure 3, a foam plate P is held between the base plate and the press-on ruler ready to be cut by the heated cutting wire.
When cutting with the heated cutting wire, proceed as follows:
  • a) Push the plate P to be cut as far under the pressure cutting ruler as is to be cut off.
  • b) press the pressure-cutting ruler onto the plate to hold it in the desired position.
  • c) press the bracket B with the cutting wire 6 with its arms against the support strips 5 so that current flows through the wire 6 and this heats up.
  • d) with constant pressure on the strips 5, guide the bar downwards and cut.

Die Anschläge 12 unter der Grundplatte 1 können als An­schlag an bereits verlegten Platten dienen.
Besteht die zu schneidende Platte P aus Glaswolle, muss sie mit einem Messer geschnitten werden. Damit der Schnitt senkrecht zur Plattenoberfläche verläuft, muss das Messer richtig geführt werden. Es wird dabei entlang dem Anpress-­Schneidlineal geführt. Damit der Schnitt senkrecht zur Plattenoberfläche verläuft, ist in einem Vorsprung 14 der Grundplatte 1, eine Führungsnut 15 für die Führung der Messerspitze vorgesehen.
Auf der Grundplatte 1 kann auch noch eine Anschlagleiste 4 befestigt sein, die der Plattenführung dient.The stops 12 under the base plate 1 can serve as a stop on already laid plates.
If the plate P to be cut is made of glass wool, it must be cut with a knife. The knife must be guided correctly so that the cut is perpendicular to the plate surface. It is guided along the pressure cutting ruler. So that the cut runs perpendicular to the plate surface, a guide groove 15 is provided in a projection 14 of the base plate 1 for guiding the knife tip.
A stop bar 4 can also be attached to the base plate 1, which serves to guide the plate.
