Abstract
Description
Die Erfindung schafft einen Schraubenkopf mit einer darin ausgebildeten Eingriffs-Ausnehmung (Konkavität), welche eine Mehrzahl von sich radial erstreckenden konischen Ausnehmungen aufweist und für verschiedene Schraubenbits geeignet ist.The The invention provides a screw head having a therein formed Engaging recess (concavity), which a plurality of radially extending conical recesses and for different screw bits is suitable.
Eine
herkömmliche
Schraube, wie in
Mit der vorliegenden Erfindung wird eine Schraube mit einem Schraubenkopf geschaffen, bei welchem die radial verlaufenden Ausnehmungen jeweils gekrümmte Innenseiten und eine kleiner Öffnung aufweisen, welche mit einem Mittelabschnitt der Eingriffs-Ausnehmung in Verbindung steht. Es sind Schraubenbits mit unterschiedlicher Form und Größe geeignet, mit den radialen Ausnehmungen und dem Mittelabschnitt der Eingriffs-Ausnehmung in Eingriff zu sein.With The present invention is a screw with a screw head created in which the radially extending recesses respectively curved Insides and a small opening having, which with a central portion of the engagement recess communicates. There are screw bits with different Suitable shape and size, with the radial recesses and the central portion of the engagement recess to be engaged.
Die vorliegende Erfindung schafft eine Schraube, die einen Kopf, einen Schaft und an dem Schaft ausgebildete Gewindegänge aufweist. Eine in der Oberseite des Kopfes ausgebildete Eingriffs-Ausnehmung weist einen Mittelabschnitt und eine Mehrzahl von radialen Ausnehmungen auf, die um den Mittelabschnitt herum und in Verbindung mit dem Mittelabschnitt angeordnet sind. Jeder der radialen Ausnehmungen weist zwei Innenseiten und eine Endfläche auf, die zwischen den beiden Innenseiten eingefügt ist und die radiale Ausnehmung an der dem Mittelabschnitt gegenüberliegenden Seite begrenzt. Der Endfläche gegenüberliegend ist zwischen den zwei Innenseiten eine Öffnung vorgesehen. Zwei (gedachte) Verlängerungslinien der zwei Innenseiten einer jeden Ausnehmung kreuzen sich in der Mitte des Mittelabschnitts. Die Öffnung befindet sich im Übergang zwischen den radialen Ausnehmungen und dem Mittelabschnitt der Eingriffs-Ausnehmung. Die Weite der Öffnung ist kleiner als die Breite der Endfläche.The The present invention provides a screw comprising a head, a head and a head Shank and formed on the shaft threads. One in the top The engaging recess formed in the head has a central portion and a plurality of radial recesses formed around the central portion are arranged around and in connection with the central portion. Each of the radial recesses has two inner sides and one end face on, which is inserted between the two inner sides and the radial recess at the middle section opposite Limited page. The endface opposite is provided between the two inner sides of an opening. Two (imaginary) extension lines the two insides of each recess intersect in the Middle of the middle section. The opening is in transition between the radial recesses and the central portion of the engagement recess. The width of the opening is smaller than the width of the endface.
