Definitions
- the invention relates to a flexible marking cord, which can advantageously be rolled up in a container containing paint, and which has color-emitting, spaced-apart marking points, and to methods for producing such cords.
- a marking device has become known from US Pat. No. 4,152,836, which consists of a non-stretchable metal wire serving as a core and a flexible sleeve with marking points which is pulled over the wire; it is expressly emphasized that this marking device resists changes in length. Neither this wire core nor the sleeve can therefore be stretched elastically. Because of the special stiffness of the non-stretchable wire core, it would also have no practical significance if the sleeve were made to be elastically stretchable; this would shortly be pierced by the wire and become unusable. It is also through. the use of the wire core and the sleeve pulled over this known structure is very complicated.
- Such sleeves or sleeve parts hinder the mobility of such cords; they also make the cords heavy so that they can sag when in use, which detracts from the accuracy of the marking.
- the elastically stretchable marking cord according to the invention is not hindered in its use, so that with a single cord very large differences in distance between the marking knobs and very large differences in length of the walls to be marked or the like. can be mastered.
- the marking cord according to the invention is therefore not only simpler, but also more powerful.
- the cord according to the invention is advantageously made of round rubber which is woven into fabric and which has the marking points, e.g. Pimples, is provided.
- the rubber-woven fabric has an extensibility of up to 230%, and the raw rubber has an extensibility of up to 600%, which is a great advantage in practice because the scope of use is extraordinarily large.
- a method for producing a cord according to the invention is characterized in that the color-emitting marking points, in particular the knobs, are sewn onto the temporarily extended cord, in particular onto the temporarily extended rubber cord, or sewn into the latter.
- FIG. 1 shows a flexible marking cord in the simplest design
- FIG. 2 shows a marking cord with an associated paint container
- FIG. 3 shows a marking made with it
- FIG. 4 shows the arrangement of pipe clamps produced in this way and an insulating pipe or the like held thereby. for electrical cables.
- the flexible marking cord 1 according to FIG. 1 consists of elastic round rubber which is woven into the fabric and which is provided with knobs 2. Instead of the two knobs shown here, several can also be provided, as can be seen in FIGS. 2 and 3.
- the knobs 2 are sewn in or on in the extended rubber, for example every 65 cm. This distance can be chosen according to the maximum length.
- the Nubs 2 reduce their distance evenly when the rubber is left behind.
- the marking cord is rolled up in a cord box 3 (Fig. 2), which is filled with paint, so that the rubber and the knobs are soaked with this paint.
- the marking cord is stopped according to Figures 2 and 3 as required on the ceiling, wall or floor and pulled to the correct length; Then the rubber cord is plucked and this transfers the color to the ceiling, wall or floor.
- FIG. 3 also illustrates, after the marking line 4 has been produced by the rubber cord 1 and the division marks 5 by the knobs 2 or the like by means of a drilling machine 6. e.g. the openings 7 for dowels or clamps or the like. 4 finally shows an insulating tube 8 which is held by means of clamps 9 which are in the aforementioned openings 7, e.g. are anchored via dowels attached to the clamps or the like.
- the marking device according to the invention with an elastically stretchable cord which carries only the color-emitting knobs on its surface, is easy to handle and, because of the low workload in the production and use, results in an enormous saving of time.
- it is particularly suitable for determining clamp spacings; but it can also be used for mounting cable trays and for marking special mounting clearances. It can also be used for carpentry to determine the distances, for example with slatted frames. You hold the rubber or the like on the wall. stretch it until the distance between the first two knobs has reached the desired length, and the remaining distances result automatically from the stretch. The same applies to wallpapering work for measuring the wallpaper spacing.
- knobs not only mark the knobs, but also the surrounding of the rubber takes up color and thus a line can also be marked.

Description
Die Erfindung betrifft eine biegsame Markierungsschnur, die vorteilhaft in einem Farbe enthaltenden Behälter aufrollbar ist, und die farbabgebende, voneinander distanzierte Markierungsstellen aufweist und Verfahren zur Herstellung solcher Schnüre.The invention relates to a flexible marking cord, which can advantageously be rolled up in a container containing paint, and which has color-emitting, spaced-apart marking points, and to methods for producing such cords.
Durch die US-PS 4 152 836 ist eine Markierungsvorrichtung bekannt geworden, die aus einem als Seele dienenden nicht dehnbaren Metalldraht und einer biegsamen über den Draht gezogenen Hülse mit Markierungsstellen besteht; dabei wird ausdrücklich betont, daß diese Markierungsvorrichtung Längenänderungen widersteht. Weder diese Drahtseele noch die Hülse sind also elastisch dehnbar. Wegen der besonderen Steifigkeit der nicht dehnbaren Drahtseele hätte es auch keine praktische Bedeutung, wenn man die Hülse elastisch dehnbar ausführen würde; diese würde in Kürze vom Draht durchstoßen und unbrauchbar werden. Außerdem ist durch. die Verwendung der Drahtseele und der darüber gezogenen Hülse dieser bekannte Aufbau sehr kompliziert.A marking device has become known from US Pat. No. 4,152,836, which consists of a non-stretchable metal wire serving as a core and a flexible sleeve with marking points which is pulled over the wire; it is expressly emphasized that this marking device resists changes in length. Neither this wire core nor the sleeve can therefore be stretched elastically. Because of the special stiffness of the non-stretchable wire core, it would also have no practical significance if the sleeve were made to be elastically stretchable; this would shortly be pierced by the wire and become unusable. It is also through. the use of the wire core and the sleeve pulled over this known structure is very complicated.
Die aufgezeigten Nachteile werden bei einer biegsamen Markierungsschnur, die vorteilhaft in einem Farbe enthaltenden Behälter aufrollbar ist, und die farbabgebende, voneinander distanzierte Markierungsstellen aufweist, erfindungsgemäß dadurch vermieden, daß die Schnur elastisch dehnbar ist und an ihrer Oberfläche nur die farbabgebenden Markierungsstellen, z.B. Noppen, trägt, keineswegs aber die vorerwähnten bekannten Hülsen.The disadvantages indicated are avoided according to the invention in the case of a flexible marking cord which can advantageously be rolled up in a container containing paint and which has color-releasing, spaced-apart marking points, in that the cord is elastically stretchable and only the color-releasing marking points, e.g. Knobs, wears, but in no way the aforementioned known sleeves.
Solche Hülsen bzw. Hülsenteile behindern übrigens die Beweglichkeit solcher Schnüre; sie machen die Schnüre außerdem schwer, so daß sie bei der Verwendung durchhängen können, was der Exaktheit der Markierung abträglich ist.Such sleeves or sleeve parts hinder the mobility of such cords; they also make the cords heavy so that they can sag when in use, which detracts from the accuracy of the marking.
Selbst wenn man die bekannte Hülse elastisch ausführen würde, würde deren Beweglichkeit durch den beim Bekannten vorgesehenen steifen Draht behindert werden, weil eine elastische Hülse bei einer Längendehnung sich innen verengt und sich an die Drahtseele anlegt. Deshalb ist wohl auch von einer elastischen Ausführung in der US-PS 4 152 836 nicht die Rede, sondern vielmehr von einem Widerstand gegen Längendehnungen.Even if the known sleeve were to be made elastic, its mobility would be hindered by the stiff wire provided in the known art, because an elastic sleeve narrows on the inside during elongation and lies against the wire core. Therefore probably not an elastic design in US Pat. No. 4,152,836, but rather a resistance to elongation.
Demgegenüber wird die erfindungsgemäße elastisch dehnbare Markierungsschnur bei ihrer Verwendung nicht behindert, so daß mit einer einzigen Schnur sehr große Abstandsunterschiede der Markierungsnoppen und sehr große Längenunterschiede der zu markierenden Wände od.dgl. beherrscht werden können. Die erfindungsgemäße Markierungsschnur ist somit nicht nur einfacher, sondern auch leistungsfähiger.In contrast, the elastically stretchable marking cord according to the invention is not hindered in its use, so that with a single cord very large differences in distance between the marking knobs and very large differences in length of the walls to be marked or the like. can be mastered. The marking cord according to the invention is therefore not only simpler, but also more powerful.
Vorteilhaft wird die Schnur nach der Erfindung aus Rundgummi hergestellt, der in Stoff eingewebt ist, und der mit den Markierungsstellen, z.B. Noppen, versehen ist. Der mit Stoff umwebte Gummi hat eine Dehnbarkeit bis 230%, und der Rohgrummi weist eine Dehnbarkeit bis 600% auf, was für die Praxis ein großer Vorteil ist, weil damit der Verwendungsumfang außerordentlich groß wird.The cord according to the invention is advantageously made of round rubber which is woven into fabric and which has the marking points, e.g. Pimples, is provided. The rubber-woven fabric has an extensibility of up to 230%, and the raw rubber has an extensibility of up to 600%, which is a great advantage in practice because the scope of use is extraordinarily large.
Gemäß der weiteren Ausgestaltung der Erfindung ist ein Verfahren zur Herstellung einer erfindungsgemäßen Schnur dadurch gekennzeichnet, daß die farbabgebenden Markierungsstellen, insbesondere die Noppen, auf die vorübergehend ausgedehnte Schnur, insbesondere auf die vorübergehend ausgedehnte Gummischnur, aufgenäht bzw. in diese eingenäht werden.According to the further embodiment of the invention, a method for producing a cord according to the invention is characterized in that the color-emitting marking points, in particular the knobs, are sewn onto the temporarily extended cord, in particular onto the temporarily extended rubber cord, or sewn into the latter.
Die Erfindung wird an Hand der Zeichnung beispielsweise beschrieben. Dabei zeigen Fig. 1 eine biegsame Markierungsschnur in einfachster Ausführung, Fig. 2 eine Markierungsschnur mit zugehörigem Farbbehälter, Fig. 3 eine hiermit hergestellte Markierung und schließlich Fig. 4 die auf diesem Weg hergestellte Anordnung von Rohrschellen und ein dadurch gehaltenes Isolierrohr od.dgl. für elektrische Leitungen.The invention is described for example with reference to the drawing. 1 shows a flexible marking cord in the simplest design, FIG. 2 shows a marking cord with an associated paint container, FIG. 3 shows a marking made with it, and finally FIG. 4 shows the arrangement of pipe clamps produced in this way and an insulating pipe or the like held thereby. for electrical cables.
Die biegsame Markierungsschnur 1 nach Fig. 1 besteht aus elastischem Rundgummi, der in Stoff eingewebt ist, und der mit Noppen 2 versehen wird. Statt der hier gezeigten zwei Noppen auch mehrere vorgesehen sein, wie die Fig. 2 und 3 erkennen lassen. Die Noppen 2 werden im ausgedehnten Gummi, z.B. alle 65 cm, ein- oder aufgenäht. Diesen Abstand kann man je nach Höchstlänge beliebig wählen. Die Noppen 2 verringern beim Zurücklassen des Gummis gleichmäßig ihren Abstand.The
Die Markierungsschnur wird in einem Schnurlkasten 3 (Fig. 2), der mit Farbe gefüllt ist, aufgerollt, damit der Gummi und die Noppen mit dieser Farbe getrankt werden. Die Markierungsschnur wird gemäß den Fig. 2 und 3 je nach Bedarf an der Decke, der Wand oder dem Boden angehalten und auf die richtige Länge gezogen; dann wird an der Gummischnur gezupft und diese überträgt die Farbe an die Decke bzw. Wand bzw. den Boden.The marking cord is rolled up in a cord box 3 (Fig. 2), which is filled with paint, so that the rubber and the knobs are soaked with this paint. The marking cord is stopped according to Figures 2 and 3 as required on the ceiling, wall or floor and pulled to the correct length; Then the rubber cord is plucked and this transfers the color to the ceiling, wall or floor.
Der Unterschied gegenüber den außerdem bekannten unelastischen einfachen Markierungsschnüren besteht vor allem darin, daß man erfindungsgemäß durch die eingenähten Noppen auch gleich die genauen Abstände mit überträgt; bei den herkömmlichen Geräten muß nach dem Aufbringen der Markierungslinie vermittels der unelastischen Schnur ohne Noppen erst die Strecke abgemessen, die Teilung errechnet und diese Teilung wiederum erst aufgetragen werden. Erfindungsgemäß erspart man sich das Vermessen, das Ausrechnen sowie das nochmalige Messen und Auftragen.The difference compared to the also known inelastic, simple marking cords is, above all, that according to the invention the exact distances are also transmitted through the sewn-in knobs; in the conventional devices, after the marking line has been applied, the distance must first be measured using the inelastic cord without knobs, the division calculated and this division again applied. According to the invention, there is no need to measure, calculate, and measure and apply again.
Wie Fig. 3 zusätzlich veranschaulicht, werden nach Herstellung der Markierungslinie 4 durch die Gummischnur 1 und der Teilungsmarken 5 durch die Noppen 2 mittels einer Bohrmaschine 6 od.dgl. z.B. die Öffnungen 7 für Dübel bzw. Schellen od.dgl. gebohrt, Fig. 4 zeigt schließlich ein Isolierrohr 8, das mit Hilfe von Schellen 9 gehalten wird, welche in den vorerwähnten Öffnungen 7, z.B. über an den Schellen befestigten Dübeln od.dgl., verankert sind.As FIG. 3 also illustrates, after the marking line 4 has been produced by the
Abschließend ist hervorzuheben, daß das erfindungsgemäße Markierungsgerät mit einer elastisch dehnbaren Schnur, die an ihrer Oberfläche nur die farbabgebenden Noppen trägt, einfach zu handhaben ist und wegen des geringen Arbeitsaufwandes bei der Herstellung und bei der Verwendung eine enorme Zeitersparnis ergibt. Wie oben dargelegt, ist es zum Bestimmen von Schellenabstanden besonders geeignet; es kann aber auch bei der Kabeltassenmontage und für die Markierung besonderer Montageabstände genutzt werden. Weiters kann es bei Tischlerarbeiten zur Bestimmung der Abstände, z.B. bei Lattenrosten, eingesetzt werden. Man hält den Gummi an die Wand od.dgl. an, dehnt ihn so lange, bis der Abstand der ersten zwei Noppen die gewünschte Länge erreicht hat, und die restlichen Abstände ergeben sich durch die Dehnung automatisch. Ähnliches gilt für Tapezierarbeiten zum Messen der Tapetenabstände.Finally, it should be emphasized that the marking device according to the invention with an elastically stretchable cord, which carries only the color-emitting knobs on its surface, is easy to handle and, because of the low workload in the production and use, results in an enormous saving of time. As stated above, it is particularly suitable for determining clamp spacings; but it can also be used for mounting cable trays and for marking special mounting clearances. It can also be used for carpentry to determine the distances, for example with slatted frames. You hold the rubber or the like on the wall. stretch it until the distance between the first two knobs has reached the desired length, and the remaining distances result automatically from the stretch. The same applies to wallpapering work for measuring the wallpaper spacing.
Es besteht die Möglichkeit, die Noppen aus PVC-Filz herzustellen und aufzukleben. Mit entsprechenden Klebemitteln halten die Noppen ausgezeichnet. Durch die Verwendung dieses PVC-Filzes, der besser Farbe aufnimmt als die genähten Noppen, werden die Markierungspunkte noch deutlicher sichtbar.It is possible to make and stick the knobs out of PVC felt. The pimples hold up well with the appropriate adhesives. By using this PVC felt, which absorbs color better than the sewn knobs, the marking points become even more visible.
Weiters ist noch zu bemerken, daß nicht nur die Noppen markieren, sondern auch die Umwebung des Gummis Farbe aufnimmt und dadurch auch ein Strich mitmarkiert werden kann.Furthermore, it should be noted that not only mark the knobs, but also the surrounding of the rubber takes up color and thus a line can also be marked.
