For secure anchoring in the wall, we lohe before the Breaking the breaking point should be achieved is it Particularly useful if the «anchoring parts that can be inserted into the wall are self-anchoring radial parts» Has radial fingers arranged like a star. These can be easily inserted into a hole, but they work in Opposite direction barb-like * This effect can be increased by the fact that the "adial fingers or the like" Anchor part have a greater radial extent than it dea Borehole diameter ohmea ser corresponds to »and somewhat elastic bend ata are trained. They then slip under something at an angle backwards deformed position into the borehole and claw well on its inner wall.

At the outer end of the anchor part in the division of functions A stop flange is provided in a special bit with a slightly larger diameter than the diameter of the Loohungsrandes · This means that after inserting the anchor, a Blnechlagkraft achieved "which is sufficient to break the predetermined breaking points and push the sleeve and the pin together as well as to establish the quick connection between these parts."

In particular, when one or more of the aforementioned measures are combined, a fastening device, especially for insulating panels, which can be used for insulating panels of different thicknesses, is made in one piece can be made and trotaedem ensures clear sefeetigungeverhiilt conditions even with the telescopic shortening. An inaccurate holding force in the axial direction even with only a slight overlap or tilting of one of the telescopic parts with respect to the other is through the Shaping in the transition area »wipe pin and sleeve and the snap-in connection between these parts after

inserted into the wall anchor part 2 and a the insulating od. like. penetrating, designated as a whole by 3 and an armature shaft which Aui3enseite the plate cross head h au! *.

The anchor shaft 3 is composed of a pin 5 and a sleeve 6 which at least partially overlaps it and is telescopically displaceable relative to the pin 5.

Especially with reference to FIGS. 3, 5 and 6 it can be seen that before the pin 5 and the sleeve 6 are pushed together, these parts are connected to one another by predetermined breaking points 7, so that the entire fastening device 1 can be manufactured in one piece, at least in the embodiment according to FIG can. The driving resistance of the anchor part 2 to be inserted into the wall is lower than the breaking strength of the predetermined breaking points 7. This ensures that the anchor part 2 can first be driven into the holes provided during assembly before the anchor shank 3 is adjusted to the thickness The plate to be fastened is carried out by breaking the predetermined breaking points 7 and pushing the two parts forming the anchor shaft 3 together. For this purpose, a stop flange 8 with possibly a slightly larger diameter than the diameter of the perforation edge is provided in the functional position of the outer end of the anchor part 2, so that the impact resistance increases sharply when this flange 3 has reached the perforation edge. The »then leads to the breaking of the predetermined breaking points 7 when a further impact force is applied and the pin and sleeve are pushed together.

An essential embodiment of the improper fastening device 1 is that after a short pushing together of pin 5 and sleeve 6 at least one locking position acting in the axial direction is achieved. I "versions" ispd "l is provided a positive connection It can be seen above all in FIGS. 5 and 6 that the sleeve 6 is around its insertion area facing the pin 5

The teeth or the like «projections of the internal toothing 9 of the Hill se 6 and those of the external toothing 10 of the pin 5 run in the exemplary embodiment over the entire circumference, so that the two parts 5 and 6 can also be tilted against each other Connection with Ztxsarmnonöchieben results. The toothing 10 of the pin 5 rises, withdrawn from the B inste device, in the sleeve achrilg and then falls steeply in each case. Such a serrated toothing 10 allows a relatively simple reassembly, but prevents a subsequent loosening in the opposite direction from a desired high resistance. Even if the two parts 5 and 6 are pushed together relatively slightly, the result is a sufficiently secure fixing of a relatively thick plate. "

Execution of eboi game according to PIc. 6 iat shown that the cross-section of the internal toothing $ of the sleeve can also be approximately wave-shaped. Since such an internal toothing is easy to produce and yet, when interacting with a saw-like external toothing 10, results in an almost linear hold as in the embodiment according to FIG for the production of the interior profile and toothing: the sleeve 6 by means of a core needle of its own inventive importance, which is characterized in that a core needle, not shown in the drawing, is used with a counter-profile approximately corresponding to the internal toothing 9 and this core needle is still tin-hardened Kunstatoffee the fastening device is »pulled» out of it. This means that a simple core needle can be used, since the undulating profile yields somewhat when it is pulled out, but without disappearing. After hardening, there is sufficient internal toothing 9. Special measures as a sharp formation

-like profiling of the inside verisalmun £ s | can be avoided.In addition, the one-piece production of the said Berosti ^ uncsvorrichtunft is thereby facilitated with the arrangement of the predetermined parts at the transition area between the pin and the sleeve. It is also made possible _for the pin 5 to protrude into the interior of the sleeve with a shoulder before being driven into the ileus 6, which with its circumference opposite the inside of the sleeve 6, with the exception of in the axial direction, preferably over the cresamten l ^! Overlap area extending connecting ribs 13 maintains a small Abctand. This can be achieved by means of a core needle which is hollow in its front area and which has slots on the front side corresponding to the Arihindunjsrippen. This embodiment has the advantage that from the very first moment the two parts that can be pushed into one another are safely guided against each other) so that tilting of the part having the head relative to the other part can be avoided.

In the axial direction, in continuation of the attachment 11 having the attachment ribs 13, a guide area 14 is provided on the pin 5, the outer diameter of which corresponds approximately to the inner diameter of the sleeve 6. This is a further measure for the safe joining of the two telescopic parts that can be slid into one another while at the same time avoiding a kink with an even slight overlap "

According to FIGS. 3 and k , the anchor part 2 which can be inserted into the wall has radial parts which are self-anchoring, radial fingers 15 arranged in a star-like manner in the exemplary embodiment. The radial fingers 15 in »Execution belly ·! a "greater radial extent it ale * about the matching particular dom HUlaenaußendurchmosaer Bohrlochdurohmesser corresponds _f and they are about aueijebildet" elastically pliable. When the anchor arm 2 is driven in, the radial finjjer 15 are therefore bent back a little and can hook-like claws into the borehole wall. Due to the fact that the outer diameter of the sleeve corresponds to each other

and borehole diameters can also be advantageously implemented when drilling the hole in the wall and in the insulation flat a step drill can be avoided.

The manufacture of the fastening device 1 is particularly simple if - as shown in the exemplary embodiment - the pin 5 is connected to the anchor part 2 and the sleeve 6 is connected to the dome head k . The above-mentioned core needle oil for producing the sleeve 6 can then be easily withdrawn from the head. If the arrangement is reversed, the armature part would also have to be hollow for such a manufacture.

Since the Befest icungavorrichtung 1 erfindunssgeiaiiß to different plates conformable, it may also be appropriate "a, to adjust the plates Cross-area corresponding · do so, in Ausführunfjsbeiapiel a central Loohung l6 having a diameter approximately corresponding to the outer diameter of the Ankeraohaftes 3 - in particular of the sleeve 6 - having additional elements 17 with radially protruding arms 18 to enlarge the stop surface ßregenütoer an insulating plate or the like. Provided. The fastening device tune 1 can thus be inserted through the looper 16, whereby with the aid of the additional element 17 a considerable enlargement of the head k occurs. An additional element 17 can be provided with at least two, preferably three or, as in the exemplary embodiment, four arms 18 protruding radially and in a star shape, which can be partially overlapped by the head of the fastening device 1. Especially in Pig. 2 and also in PIs. 7 it can be seen that the additional element 17 in its central area, from which the arms 18 extend, has an insert 19 corresponding to the foot contour of the head h , at the bottom of which the perforation 16 for inserting the anchor shaft 3 of the fastening device 1 is arranged. This enables the head k to be lowered into such an additional element, so that when it is used, the area of this baffle is still on the outside of an insulating plate or the like.

The lightweight board is not provided with too many shoulders.

The lower sides of the arms 16 of the additional element 17 facing the plate to be held in the functional position in each case at least one preferably pointed projection 20, wherein in the exemplary embodiment such a projection 20 is provided on the ends of the arms. Furthermore is however, such a projection 20 is also indicated in the course of the arms.

Fig. 7 shows below the perforation 16 on the additional element 17, a basket or funnel 21, which also has a Hopf 22 of a much smaller diameter, for example of a smaller diameter than that of the perforation 16 corresponds, can reach under. As a result, the production of the actual fastening device can be simplified, because the head can have a lesser greetings and still with With the help of the additional element 17, a sufficiently large stop surface can be created with respect to a plate to be held.

Overall, there is a fastening device 1, which can be easily assembled and manufactured and can still be adapted to different panel thicknesses with the same drill hole depth or the same binding ring length of the Anchor part 2 allowed * Even when the parts forming the anchor shank are pushed together telescopically, a Secure fastening, in which the anchor part is first fully driven in and, even with a slight overlap of the parts that can be pushed into one another, a sufficient axial one Strength is achieved. A tilting of one part in relation to the other, which adversely affects this strength is avoided. Due to the adaptability to different panels, storage is also relieved.
