Description
Die Erfindung betrifft eine Kopfschraube gemäß dem Oberbegriff des Hauptanspruchs,The invention relates to a head screw according to the preamble of the main claim,
Im Einbauzustand werden die Köpfe derartiger, handelsüblicher Schrauben häufig - meistens aus optischen Gründen - mit einer Kunststoffabdeckung versehen, die unter Ausnutzung ihrer Elastizität den Schraubenkopf eng umschließt und mit ihm eine kraftschlüssige Verbindung eingeht. Während bei nur statisch beanspruchten Schrauben die bekannten Abdeckungen im allgemeinen ausreichend sind, gibt es bei Schrauben, die zusätzlich dynamisch beansprucht werden, aber auch bei solchen, die starken Temperaturunterschieden ausgesetzt sind, immer wieder Probleme bezüglich eines dauerhaften Festsitz 3S der Abdeckung.When installed, the heads of such commercially available screws are often - mostly for aesthetic reasons - provided with a plastic cover which, using its elasticity, tightly encloses the screw head and forms a force-fit connection with it. While the known covers are generally sufficient for screws which are only subject to static stress, there are always problems with the permanent tight fit of the cover for screws which are also subject to dynamic stress, but also for those which are exposed to strong temperature differences.
Der Erfindung liegt die Aufgabe zugrunde, hier Abhilfe zu schaffen und durch eine konstruktive Maßnahme ein Abfallen der Abdeckung vom Schraubenkopf zu verhindern. Mit rien kennzeichnenden Merkmalen des Hauptanspruchs wird die Aufgabe in einfacher Weise gelöst. Durch den Hinterschnitt, in den die Abdeckkappe vorzugsweise mittels besonderer nach innen gerichteter Vorsprünge eingreift, wird aus der bekannten kraftschlüssigen Verbindung nun eine formschlüssige.The invention is based on the object of remedying this situation and using a constructive measure to prevent the cover from falling off the screw head. The object is solved in a simple manner using the characterizing features of the main claim. The undercut, into which the cover cap preferably engages by means of special inward-facing projections, turns the known force-fitting connection into a form-fitting one.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung; in der eine vorschlagsgemäße Sechskantschraube mit einer Scheibe und - strichpunktiert - sine dazu passende Abdeckkappe dargestellt sind, näher erläutert.An embodiment of the invention is explained in more detail below with reference to the drawing; in which a proposed hexagon screw with a washer and - in dash-dotted lines - a matching cover cap are shown.

Die Sechskantschraube umfaßt einen Schraubenkopf i und einen Gewindeschaft 2, auf dem eine Scheibe 3 angeordnet ist. Der dem Gewindescfiäft 2 zugekehrte Bereich 4 des Kopfes 1 hat die Form eines Kegelstumpfes, dessen der Scheibe 3 benachbarte Querschnittsfiäche 5 immer noch deutlich großer ist als der Querschnitt des Gewindeschaftes 2, so daß der Kegelstumpf 4 an seiner Unterseite eine kreisringförmige Auflageflache 6 hat, mit der sich der Schraubenköpf 1 auf der Scheibe 3 abstützt* Die Scheibe 3 kann angeformt öder als separates Teil auf den Gewihdeschäft 2 aufgesteckt sein. Der Kegelwinkel öC des Kegelstumpfes 4 beträgt vorzugsweise etwa 6ÖÖ. The hexagon screw comprises a screw head 1 and a threaded shaft 2 on which a disk 3 is arranged. The area 4 of the head 1 facing the threaded shaft 2 has the shape of a truncated cone, the cross-sectional area 5 of which adjacent to the disk 3 is still significantly larger than the cross-section of the threaded shaft 2, so that the truncated cone 4 has a circular bearing surface 6 on its underside, with which the screw head 1 rests on the disk 3. The disk 3 can be molded onto the threaded shaft 2 or attached as a separate part. The cone angle δC of the truncated cone 4 is preferably about 6δδ .
Auf den Schraubenkopf 1 ist eine Abdeckkappe 7 aus elastischem Kunststoff aufgekÜpst. Sie hat einen flachen Kopf 8 und einen im wesentlichen zylindrischen Klemmteil 9 mit wenigstens einem, am freien Ende des Kiemmteils angeformten, nach innen gerichteten Fortsatz 10, der das Oberteil des Sßhraubenkopfes 1 federnd hintergreift und so eine formschlüssige Verbindung zwischen Schraubenkopf 1 und Abdeckkappe 7 herstellt.A cover cap 7 made of elastic plastic is clipped onto the screw head 1. It has a flat head 8 and a substantially cylindrical clamping part 9 with at least one inwardly directed extension 10 formed on the free end of the clamping part, which springily grips behind the upper part of the screw head 1 and thus creates a positive connection between the screw head 1 and the cover cap 7.
