- the screw head 16 is slightly narrower than the slot 14 of the Mounting rail 12, its shorter diagonal is longer than the width of the slot 14, but shorter than an inner width of the mounting rail 12. A longer one Diagonal of the screw head 16 is slightly longer than the inside width of the Mounting rail 12.
- a perforated disc 20 as a clamping element on one Screw shaft 22 of the hammer head screw 10 pushed on.
- the perforated disc 20 is provided with four short slots 24, which are in pairs with some distance from each other and opposite to the other two slots 24 on the circumference of the perforated disk 20 are attached.
- a rubber ring 26 as Tension spring element stretched over the screw head 16. The rubber ring 26 pulls the Perforated disk 20 against the screw head 16.
- a diameter of the perforated disk 20 is greater than the width of the slot 14 of the fastening rail 12.
- a nut 28 at a distance from the perforated disk 20 screwed onto the screw shaft 22.
- the nut 28 is twisted with a drop that is not visible in the drawing Securing lacquer secured in a manner known per se. Tightening the nut 28 will not hindered by this.
- the attachment of the hammer head screw 10 according to the invention on the Fastening rail 12 happens as follows:
- the hammer head screw 10 is with its screw head 16 aligned in the longitudinal direction of the slot 14 through the Slot 14 inserted into the interior of the mounting rail 12.
- the Perforated disc 20 on an outside of the mounting rail 12 to the plant, it will raised against the force of the rubber ring 26 from the screw head 16.
- the hammer head screw 10 in the Locking rail 12 locked ends of the screw head 16 engage behind it Rectangular tube profile of the mounting rail 12 on the side of the slot 14.
- the rubber ring 26 presses the perforated disc 20, which rests on the outside of the fastening rail 12 Hammer head screw 10 in the axial direction from the mounting rail 12 and thereby the screw head 16 in contact with the inside of the fastening rail 12.

- the Hammer head screw 10 by tightening the nut 28 with the mounting rail 12 braced.
- the parallelogram-shaped screw head 16 whose longer diagonal is longer than is an inner width of the mounting rail 12, limits the angle of rotation of the Hammer head screw 10, since the corners of the Bump the screw head 16 on the inside of the mounting rail 12 when the Screw head 16 has been rotated approximately perpendicular to the mounting rail 12 is.
- the rubber ring 26 After tightening the nut 28, the rubber ring 26 has no function, so that aging of the rubber ring 26 does not affect the function of the hammer head screw 10 impaired.
- the perforated disc 20 of the invention shown in Figure 3 Hammer head screw 10 has four indentations 30 of its peripheral edge that serve to attach the rubber head 26 spanning the screw head 16.
- FIG. 4 Another embodiment of a tension spring element is shown in FIG. 4. This is shown as cord-shaped rubber band 32 with drop-shaped thickenings 34 at its ends educated. The thickenings 34 are for hanging in two each other Opposing slots of a perforated disc, not shown, are provided. The Rubber band 32 spans the screw head 16.
- the tension spring element shown in top view in FIG. 5 is a wide rubber band 36 formed with slots 38 at its ends.
- the rubber band 36 spans the Screw head 16. It is one with its slots 38 over the circumferential edge conventional, not shown, circular perforated disc.
- This Design of the tension spring element has the advantage that a conventional Perforated disc without slots instead of the perforated disc 20 shown in Figure 2 as Clamping element can be used.
- FIG. 6 shows an embodiment of a hammer head screw 10 according to the invention, which has a compression spring element instead of a tension spring element.
- Compression spring element uses a spring ring 40 known per se, which is a full turn around the screw shaft 22 and which has an incline. This is between the perforated disc 20 and the nut 28 on the screw shaft 22 postponed. He resiliently presses the perforated disk 20 against the screw head 16.
- This embodiment of the invention has the advantage that a conventional circular Perforated disc 20 without slots can be used as a clamping element.
- the hammer head screw 10 shown in FIG. 6 has the same structure as that in FIG 2 hammer head screw 10 shown and works in the same way, it will insofar referred to the explanations for Figures 1 and 2.
- the spring force of the spring ring 40 (like the rubber ring 26) is so weak chosen that the screw head 16 with little force in the Press mounting rail 12, and that the hammer head screw 10 with little effort against the clamping force of the spring ring 40 in the longitudinal direction of the Fixing rail 12 can move.
- the spring force of the spring ring 40 so high that the hammer head screw 10 even when mounted vertically Fixing rail 12 clamps against the action of gravity.
- Corrugated spring washers come, for example, as compression spring elements Disc springs into consideration.
- Another compression spring element is shown in FIG. This consists of a perforated disc 42 with four one-piece spring tongues 44, the protrude outward at an angle to the perforated disc 42.
- the spring tongues 44 can also be designed to protrude inwards or in the tangential direction.
- the compression spring element shown in Figure 8 is a conical spring 46 which between the Nut 28 and the perforated disc 20 is arranged.
- the cone spring 46 is at Tension the hammer head screw 10 flat on the mounting rail 12 compressed, the individual turns of the conical spring 46 spiral interlock and form a flat contact surface for the nut 28.
- Figure 9 shows an embodiment of the hammer head screw 10, in which the underside the screw head 16 has a shoulder 48 extending transversely to its longitudinal direction having.
- the width of the shoulder 48 is slightly less than the clear width of the slot 14 of the mounting rail 12, so that after inserting the hammer head screw 10 in the mounting rail 12 and a rotation of the screw head 16 around 90 ° the shoulder 48 snaps into the slot 14. This results in an anti-twist device for the hammer head screw 10, both when unscrewing and loosening the nut 28 takes effect.
