Tool for fastening a chamber for electrical cables or the like

The present invention relates to a tool for fastening a Klaramer for electrical cables, pipes or the like on M a support, wherein the clamp of an arcuate shape and has legs that in the mounted state of the clip from the support weqra ^ s, and further comprising a centrally arranged pin, a screw shaft or the like is provided, which is directed opposite to the legs and is driven into the base.

The invention is characterized in that the tool is preferably at one end and at least along two opposite ends Sides is provided with a multitude of indentations, J into which the legs of the bracket can engage and extend from the end of the tool, where they widen step-like and wedge-like from the end, and that the end face of the tool with has excellent leadership or the like, into a correspondingly designed guide hole in the head of the bracket intervenes.

Such an inventive tool has some essential features

borrowed advantages over the previous tools. One can e.g.

The pin or screw shaft is held in the direction of friction. not only if the pin or screw shaft is perpendicular to the Pad is driven, but also when the driving direction one snitzen an angle with the base, the clamp becomes firm and safely guided. There is always a driving blow to the tool ^ Security on the head of the clamp and thus mittip on the pin or exceeded the screw shaft.

The invention also relates to a clip for fastening on the base by means of the V / Erkzeupes according to the invention. As already mentioned, the bracket is arched in shape and has a triangular shape Legs that are in the attached state of the clamp from the pad dig away; it is also provided with a largely central pin, screw shaft or the like, which leads to the legs is directed in the opposite direction and is driven into the substrate. According to the invention, the clip has a guide hole on the head which can accommodate the guide tip protruding from the end face of the tool.

The invention is now described in detail, and reference is made to the exemplary embodiments of the invention Tool and the bracket according to the invention depicting drawing. It shows:

The tool 1 has a handle 2, a guide head 3 and ' a bolt 4. At the end of the handle 21, the head 3 is by means of Bolt U attached, which is mounted in the center in a bore 12 in the handle and extends through a bore 13 in the guide head 3, the free end surface 17 of the bolt U with the head end surface 18 aligns.

The head 3 is on two opposite side surfaces 25 provided with depressions 5 which inwardly from the end face 18 and in the lateral direction (see FIG. 2) in such a step-shaped manner are designed that lateral guide ribs 22 arise. Of the

In Fig. 4, a bracket 7 is darrestellt, which on the head j ο has a bracket 24 with arcuate legs 9. The bracket is in the middle and in the opposite direction to the legs 9 with a pin, a screw shaft or the like 8 is provided. A guide hole 11 is located in the head Io of the clamp 7.

When a clamp 7 is placed on the tool 1, the bracket legs 9 are inserted into one of the sparks 5 according to their size and spread apart, while the guide tip 6 rides into the hole 11 at the same time. Ir VJerkzeu ¹ " ¹ now holds the clamp firmly and cannot be turned or tilted in any direction, even if the direction of movement of the clamp is not perpendicular to the base with the hole 11 in the clamp head Io, the driving impacts exerted on the tool are passed on centrally to the head Io of the clamp.

"The invention is not limited to the described and Design shown in the drawing. The head 3 can e.g. be attached to the handle 2 in some other way and can also be made in one piece with it, in which case the guide tip forms part of the head 3. The bottom surfaces 2o of the depressions 5, which are shown flat and inclined, can also have a different shape; you can z. B. convex or concave be curved and have any inclination to each other.

As far as the tool 1 is made in two parts from the handle 7 and the head, it is useful to connect the two parts

Bolt 4 in the region of its end face 17 with an opposite to the To provide bolt shank 15 enlarged bolt head 16 and to manufacture it from a hardened material so that the sensitive Guide tip 6 as low as possible in the course of a long period of use Is subject to wear and tear. So that the end face 17 of the bolt 4 is aligned with the head end face 18 even during the propulsive blows and cannot retreat into the interior of the guide head or the handle, an enlarged head recess 14 is provided in the guide head 3, which merges over a shoulder 23 into the tapered bore 13 for receiving the bolt, so that the associated paragraph 19 in the Bolt head 16 comes to rest on this shoulder 23 that ^ the end face 17 is aligned with the head end face 18.

When using the tool, the clamp 7 to be driven is inserted into the associated recess from below by means of the leg bracket 9 5 inserted, the legs spreading due to the inclination of the bottom surfaces 2o of the respective recess until the guide tip 6 of the bolt 4 in the guide hole of the clamp head it penetrates Io and the clamp on this VJeise tight is held by the guide Kottf 3, so that no tilting is possible during the subsequent driving, because the side surfaces 28 ^

Legs 9 are held by the FührunPsriD ^ en 22, which to both sides of the respective recess 5 are present, as shown in Fi ^. 2 and 5 can be seen. Another safeguard against jamming is by engaging the guide tip 6 in the guide hole 11 given.
