Abstract

The tacker has the pushrod (1), punch (2) and punch guide (3) made in the form of a one-piece plastic component, onto which the handle (4) and spring holder (5) can be directly molded. The pushrod has a cross-section profile which can be produced in only two deforming devices, e.g. in the outline of a Swiss cross.

Description

Zum Setzen von Haltern zur Rohrbefestigung bei einer Fuß bodenheizung werden häufig sogenannte Tackergeräte einge setzt, die bislang aus Metall hergestellt werden. Zum einen ist der Verschleiß an derartigen Geräten durch die Reibung von Metall auf Metall sehr groß, zum anderen ist das Gewicht der Metallgeräte ein Problem. Derartige Me tallgeräte sind relativ teuer in der Herstellung, so daß sich eine Anschaffung derartiger Geräte nur für Firmen lohnt, die häufiger Fußbodenheizungen verlegen.For placing brackets for pipe fastening on one foot Floor heating is often used in so-called tacker tools sets that were previously made of metal. To the one is the wear and tear on such devices due to the Friction from metal to metal is very large, on the other hand the weight of the metal equipment is a problem. Such me tall devices are relatively expensive to manufacture, so that a purchase of such devices only for companies worthwhile to install the underfloor heating more often.

Aufgabe der Erfindung war es, ein Gerät so zu gestalten, daß es im Kunststoffspritzgußverfahren herzustellen ist, bei dem das Eigengewicht reduziert ist und das für den harten Baustellenbetrieb geeignet ist.The object of the invention was to design a device in such a way that it can be manufactured using the plastic injection molding process, in which the dead weight is reduced and that for the tough construction site operation.

Diese Aufgabe erfüllt das Tackergerät nach den Ansprüchen 1-9.The staple gun fulfills this task according to the requirements 1-9.

Durch die kunststoffgerechte Gestaltung des Gerätes ist eine Herstellung im Spritzgußverfahren aus Kunststoff mög lich, hierdurch werden die Kosten und das Gewicht mini miert.Due to the plastic design of the device production by injection molding from plastic possible Lich, the costs and weight are mini lubricated.

Durch die spezielle Konturgebung der Stößelstange, durch die doppelte Magazinbefestigung mit dem zusätzlichen Ver bindungsteil sowie durch die Führungsnut und Verdrehsiche rung im Gehäuse ist das Gerät sehr robust und baustellen gerecht. Durch die eingesetzten Spezialmaterialen ist dieses Tackergerät sehr verschleißarm.Due to the special contour of the push rod, through the double magazine attachment with the additional ver binding part as well as through the guide groove and torsion lock The device is very robust and works on site fair. Due to the special materials used this tacker is very wear-resistant.

Durch die spezielle Bauart dieses Gerätes sind die Pro duktionskosten so weit gesenkt, daß dieses Gerät die Ein führung des Tackersystems in vollkommen neue Märkte er laubt, zum Beispiel in den DIY-Bereich.Due to the special design of this device, the Pro Production costs reduced so far that this device the one leading the tacker system into completely new markets leaves, for example in the DIY area.

Viele, bislang nötige, Zusatzarbeiten, wie das Anbringen der Rasten, der Federnhalterung oder des oberen Anschla gens sind bei den Kunststoffteilen direkt integriert und verursachen somit keine zusätzlichen Kosten. Lots of additional work that has been necessary so far, such as fitting the catches, the spring bracket or the upper connection gens are directly integrated into the plastic parts and therefore cause no additional costs.

Claims

1. tacker for pushing in holders of a Bodenbodenhei supply in the under insulation layer, characterized in that the push rod ( 1 ), the stamp ( 2 ) and the stamp guide ( 3 ) are designed as a one-piece plastic part to which a handle ( 4 ) and a spring holder ( 5 ) can be molded directly.

2. tacker according to claim 1, characterized in that the push rod ( 1 ) in the cross-section of the con has a stability and still based on low material thickness profile, which can be removed from the mold in only two directions, for example in cross-section the contour of Swiss cross.

3. Tacker device according to one of the preceding claims, characterized in that the magazine rod ( 6 ) is attached to the housing ( 7 ) at two or more points, preferably before the attachment with the screws ( 8 ) which hold the housing parts together.

4. tacker according to one of the preceding claims, characterized in that at the lower edge of the housing ( 7 ) a recess ( 9 ) is provided for fitting and partially over gripping the heating tube to be fastened.

5. tacker according to one of the preceding claims, characterized in that in the housing ( 7 ) a guide groove ( 10 ) for the stamp guide ( 3 ), an upper stop ( 11 ) and a plastic catch ( 12 ) are provided.

6. tacker according to any one of the preceding claims, characterized in that the push rod ( 1 ) and the magazine rod ( 6 ) are made of a material with a high egg strength, for example fiber-reinforced plastic, the housing ( 7 ), however, from a highly abrasion-resistant Plastic.

7. tacker according to one of the preceding claims 7, characterized in that the guide of the stamp ( 2 ) and the stamp guide ( 3 ) in the housing ( 7 ) are provided so that the push rod ( 1 ) is secured against rotation and that a correspondingly long Guide groove ( 10 ) prevents the punch guide ( 3 ) from kinking.

8. tacker according to one of the preceding claims, characterized in that the actual Schußkopfbe rich in the housing ( 7 ) and the stamp ( 2 ) are adapted to the material thickness of the holder, that the actual Ge housing but by webs ( 13 ) or frankings ( 14 ) is so reinforced that there is sufficient stability for the push rod ( 1 ) and the magazine rod ( 6 ).

9. tacker according to one of the preceding claims, characterized in that an additional connecting part ( 15 ) is provided with which the magazine rod ( 6 ) is additionally fastened to the housing ( 7 ) in order to prevent breaking of the fastening point ( 16 ).
