ボの回転に繋がる力をダボに与えることになる。[Prior Art] For example, in order to insert a leg dowel into a hole provided in a wall, a fixing member or a fixing screw is often used as an auxiliary means, and the dowel is inserted onto the fixing screw in advance. In this case, the fixing screw is only used to insert the dowel into the hole. Additionally, if the dowel is inserted very deeply, the threads of the screw must bite into the dowel material to allow the dowel to be pulled back by tightening the screw. Under no circumstances should the cutting of the thread lead to an opening action of the dowel. West German patent no.
From JP 27, 29, 828, an open leg dowel of the aforementioned type is known which is provided with a rib extending in the longitudinal direction of the dowel in the cylindrical neck of the receiving channel. When inserting the dowel, the screw thread stops at the rib. However, if it is desired to firmly connect the fixing screw and the leg dowel, it is necessary to cut a screw into the rib. Driving the threads may impose forces on the dowel that can lead to undesirable slippage and/or undesirable rotation of the dowel in the hole in the wall.

The problem of the saw invention is to connect a fixing screw to the neck of the dowel without deforming the dowel even without applying a large force, and by means of this screw, the desired position in the axial direction can be set, for example, inside a hole in a wall. The purpose is to provide a leg dowel that can be inserted into the.

The protuberance according to the present invention on the cylindrical part of the receiving passage not only solves the above problems, but also eliminates the possibility of displacement of the dowel when the screw is pressed in the axial direction of the dowel, and allows the fixing screw to be completely inserted into the dowel afterwards. Another advantage is that it can be screwed into the In that case, the at least one protuberance engages with the thread for rotation of the screw which generates a thrust in the axial direction of the dowel, the rotation of which allows the screw for opening the dowel to be inserted into the dowel.

に配設してある。 The legs of the dowel are connected to each other in a manner known per se via the target interposition, so that the legs assume the desired shape. However, it is clear that if the connecting piece connecting the legs at the end of the dowel is arranged in a known manner towards the axis of the dowel, the screw will deviate from the axis of the dowel when screwed in further.
According to a preferred embodiment of the invention, therefore, a connecting piece is provided between the legs of the dowel forming a target gap at the end of the dowel, the legs intersecting in the longitudinal direction of the dowel. The dowels are spaced apart from each other and are disposed on both sides of the axis of the dowel.

仕上げてある。 The substantially cylindrical leg dowel 2 is shown in FIGS. 4 and 5.
As shown, there is a receiving passageway 4 extending over most of its length. This receiving passage is shown in dotted lines in FIGS. 1 and 2. At the neck 6 of the dowel,
The receiving channel has a flared cylindrical section 8, which transitions via a conical inner wall 10 into a tube section 12 of rectangular cross section extending over most of the entire length of the dowel legs 14, 16. do. Both legs are formed by one slit 18. This slit extends from the tip 20 of the dowel to the neck 6,
There is a transition between the straight initial section 22 and the straight final section 24 in the form of two undulating slit sections 26,28. Since the wavy lines of both slit parts are shifted from each other in the longitudinal direction, as can be seen from Figure 1, the crest of the wave of one slit part and the trough of the wave of the other slit part are perpendicular to the longitudinal direction of the dowel. are facing each other. This waveform is finished in a flat zigzag shape.

引き裂くので、このネジは横にずれない。 Both legs 14, 16 are connected to individual wall pieces 3 disposed along the inner edges 36, 38 at both longitudinally extending slit portions 26, 28 of the dowel.
They are connected to each other by 0 to 34. As shown in FIG. 4, the wall pieces 30 to 32 are disposed offset in the longitudinal direction of the dowel with respect to the remaining wall pieces 31 and 34 disposed on the opposite edge 36 of the inner edge 38. The wall pieces 31-34 thus together form a target partition area extending in the longitudinal direction of the slit. At the tip 20 of the dowel, both legs 14 and 16 are connected to each other via connecting pieces 40 provided on both sides of the central axis of the dowel. The tip of the screw is connected to this connecting piece 4 when the legs are opened.
This screw does not displace laterally as it reaches between 0 and tears both connecting pieces under symmetrical forces.

にする割れ目防止溝５２がある。 The dowel portion connected to the neck 6 in the longitudinal direction has two recesses 42 and 44 facing each other on the circumference. Restriction tongues 46 and 48 are formed at the ends of the recesses on the tip side of the dowel, respectively. These restraining tongues curve inward when the dowel is inserted into the mounting hole. In that case, the cross sections of the recesses 42, 44 receive this tongue. The width at the base 50 of the tongues 46, 48 is made fairly wide so that both tongues do not bend laterally in response to forces acting tangentially around the dowel. Furthermore, at the base of the tongue there is an anti-split groove 52 which extends perpendicularly to the longitudinal direction of the dowel and facilitates the design of the tongue.

4, 16 have a tongue portion 46, up to the head of the dowel.
48, there is an outer shape formed by a number of split-like cutouts 54, 56. As a result, between longitudinally adjacent cutouts of the dowel there are tooth-like ridges 58, respectively.
60, but these ridges do not protrude from the outer periphery of the dowel. In this case, as can be seen from FIG. 2, two outer circumferential rows are arranged, each of which is offset by one cutout in the longitudinal direction of the dowel. In this way, one tooth-like ridge 58 on the circumference of the dowel is in each case arranged with one cutout 54 oppositely, and at the transition point there are tooth flanks 62, 64 extending in the longitudinal direction of the dowel. . These tooth surfaces counteract the rotation of the dowel when it engages the receiving channel material. Each cutout is bounded in the longitudinal direction of the dowel by two toothed surfaces 66, 68 that form an angle of 90° or more with respect to the axis of the dowel. These flanks are primarily convexly curved, as seen by flank 66 in FIG.

して伝達される。 As can be seen in FIGS. 4 and 5, two ridges 70 are arranged on the enlarged cylindrical part 8 of the receiving passage for the screw. These ridges are arranged at opposite positions on the circumference and are offset in the longitudinal direction of the dowel to match the pitch of the fixing screw.
FIG. 5 shows an embodiment of the protuberance 70 in the form of a short threaded piece. This threaded piece extends approximately in the direction of the outer circumference of the inner wall of the dowel, depending on the inclination angle of the thread. Both ridges have a width in the longitudinal direction of the dowel that is slightly less than the distance between the two threads of the fixing screw. Therefore, when screwing in a screw, these ridges engage with the screw thread without deforming it, and a connection between the dowel and the screw occurs. This connection takes up both longitudinal forces before screwing the fixing screw further into the dowel and deforming the dowel. The above thus provides the advantage that by installing a screw, the dowel can be slid into the desired position inside the hole in the wall. When the screw is further screwed in, the axial screw force generated by the ridge 70 is transmitted as a force pressing the screw into the receiving channel.
