Description
Klammer. Zur Verhinderung des Reißens von Hölzern sind bereits verschiedene Klammern in Vorschlag gebracht worden. Eine Gruppe derselben weist in die Längsachse der Klammer fallende, zur Aufnahme der Zugkräfte bestimmte Stegteile auf, aus denen in halber Höhe der Klammer gerade Zungen abgebogen sind. Eine andere Gruppe der bekannten Klammern ist ohne solche Stegteile mit abwechselnd nach entgegengesetzten Seiten gerichteten Einbuchtungen ausgebildet.Bracket. There are already various ways of preventing wood from tearing Brackets have been proposed. A group of these points in the longitudinal axis the bracket falling, to absorb the tensile forces on certain web parts, from which straight tongues are bent halfway up the clamp. Another group of known brackets is without such web parts with alternating to opposite Side-facing indentations formed.
Die Klammer gemäß der Erfindung ist ebenfalls aus Bandeisen hergestellt, sie besitzt sowohl abwechselnd nach entgegengesetzten Seiten gerichtete Einbuchtungen wie in halber Höhe der Klammer abgebogene Zungen. Die mit geraden Stegteilen abwechselnden Einbuchtungen haben aber trapezförmigen Querschnitt, und die Zungen sind aus den geraden Stegteilen entgegen der Zugkraft der Klammer stumpfwinklig über die Einbuchtungen zurückgebogen.The clip according to the invention is also made of band iron, it has indentations directed alternately towards opposite sides like tongues bent halfway up the bracket. The alternating ones with straight bridge parts Indentations but have a trapezoidal cross-section, and the tongues are from the straight web parts against the tensile force of the clamp at obtuse angles over the indentations bent back.
Durch die trapezförmige Ausbildung der Einbuchtungen und das stumpfwinklige Zurückbiegen der Zungen über die Einbuchtungen wird eine für die Wirkung vorteilhafte gewölbeartige Umfassung verhältnismäßig vieler Holzfasern erreicht; der Scheitelpunkt des Gewölbes fällt in die Richtung der Hauptbeanspruchung,_und eine Geradestreckun; der Einbuchtungen wird verhindert. .Due to the trapezoidal design of the indentations and the obtuse angle Bending the tongues back over the indentations is advantageous for the effect vault-like enclosing achieved a relatively large number of wood fibers; the vertex the vault falls in the direction of the main stress, _and a straight stretch; the indentations is prevented. .
Auf der Zeichnung sind zwei Ausführungen der neuen Klammer veranschaulicht.Two versions of the new clamp are illustrated in the drawing.
Die Klammer a aus Bandeisen ist an einen Längsrande f zur Erleichterung des @intreibens zugeschärft. In beliebiger Entfernung voneinander und abwechselnd in entgegengesetzter Richtung sind trapezfi3rmige Einbuchtungen b ausgebildet. Entlang dem nicht zugeschärften Rande sind durch je zwei Einschnitte die Zungen d freigelegt und um einen stumpfen Winkel aus der Ebene der Klammer über die Einbuchtungen zurückgebogen.The bracket a made of band iron is on a longitudinal edge f for ease of @inreibens sharpened. At any distance from each other and alternately Trapezoidal indentations b are formed in the opposite direction. Along The tongues d are exposed through two incisions on the edge that has not been sharpened and bent back over the indentations at an obtuse angle from the plane of the bracket.
Die Enden des Klammerkörpers sind in ihrer ganzen Breite ebenso zurückgebogen.The ends of the clip body are also bent back over their entire width.
