Patentiert im Deutschen Reiche vom 22. April 1906 ab.Patented in the German Empire on April 22, 1906.

Die Erfindung betrifft . ein mechanisches Glied aus Metallblech oder einem anderen federnden Stoff. Dasselbe hat einen gewölbten Rückenteil mit sich daran anschließenden Flügeln, der mit einer querverlaufenden Einknickung versehen ist, wodurch der Rückenteil eine rautenförmige oder quadratische, durch die Einknickung in zwei Dreiecke geteilte Form erhält, derart, daß die Ebenen der Dreiecke in einen Winkel zueinander gebracht und an den Spitzen gewölbt werden. Hierbei verlaufen die Seite"n der Dreiecke in die Flügel, 'so daß durch Zusammendrücken der Spitzen in der Weise, daß die Dreiecke in einen spitzeren Winkel zueinander kommen, die Flügel sich einander nähern, während beim Aufheben des Druckes sämtliche Teile des Gliedes in die erste Stellung wieder zurückfedern. The invention relates to. a mechanical link made of sheet metal or other springy fabric. The same thing has a curved back part with an adjoining one Wing, which is provided with a transverse kink, making the back part a diamond-shaped or square one, divided into two triangles by the kink Shape is given such that the planes of the triangles are at an angle to each other and be arched at the tips. Here the side "n of the triangles run in the wings, 'so that by squeezing the tips together in such a way that the triangles come at a more acute angle to each other, while the wings approach each other When the pressure is released, all parts of the link spring back into the first position.

Die fertig gebogene Platte hat eine in der Längsrichtung gewölbte Form und besteht aus einem Rückenteil α, an den sich die Flügel c anschließen. Der Rückenteil erhält durch eine querverlaufende Einknickung b eine rautenförmige oder quadratische Form und wird durch die Einknickung b in zwei Dreiecke y χy geteilt, deren Ebenen in einem Winkel zueinander stehen. An den Spitzen χ ist der Rückenteil gewölbt, während die Seiten d in die Flügel c verlaufen, die entweder gleichlaufend zueinander zusammen- oder auseinanderlaufend angeordnet sein können (vgl. Fig. 3, 3 b und 3c) und an der Innenseite hohlrund gestaltet sind. Die Flügel c sind also durch den durch Einknicken der gewölbten Platte gebildeten rautenförmigen oder quadratischen Rückenteil miteinander verbunden. The finished bent plate has an arched shape in the longitudinal direction and consists of a back part α, to which the wings c are connected. The back part is given a diamond-shaped or square shape by a transverse kink b and is divided by the kink b into two triangles y χy , the planes of which are at an angle to each other. At the tips χ the back part is curved, while the sides d extend into the wings c , which can be arranged either converging or diverging (cf. Fig. 3, 3b and 3c) and are designed to be hollow on the inside. The wings c are therefore connected to one another by the diamond-shaped or square back part formed by buckling the curved plate.

An den Enden der querverlaufenden Einkni.ckung, wo Gegenspannungen auftreten, sind Löcher i vorgesehen (Fig. 6), wodurch verhindert werden soll, daß sich das Glied am Ende der Einknickung infolge zu großerAt the ends of the transverse buckling, where counter-stresses occur, holes i are provided (Fig. 6), which is intended to prevent the link from becoming too large at the end of the buckling

Claims

Tension stretches or breaks at that point or at the side parts adjacent to the holes. In addition, this significantly increases the suspension of the device.
In order to bring the member from the rest position (Fig. 1 to 4) into the position according to Fig. Ia to 4a, the tips χ are pressed against each other, whereby the planes of the triangles are brought into a more acute angle to each other and the buckling b continues away from a line r connecting the two peaks. At the same time, the wings c (Fig. La, 2a and 3a) approach more or less, depending on the degree to which the tips χ are approaching each other. As soon as the tips are released again, all parts move into the first position ( Fig. 1 to 4) automatically back again.

The effect of the device can be in any way, for. B. by an intermediate piece g or the like arranged between the tips χ or the wings c (Fig. 5).

This link can be connected to the moving parts in any way, that the latter are either driven immediately or only when they are canceled the force affecting the limb. Leave for attaching connecting parts

Make openings s (Fig. 6) in the kink b or in the triangles or at another suitable location.

Instead of being made from one piece, the link can be made from several parts, the are connected to each other in a suitable manner.

In Fig. 7 the subject of the invention is shown as a bicycle brake. One point is connected to the frame η of the bicycle and the other point χ is connected to a wire 0 so that a braking effect can be exerted on the wheel ρ by tightening the wire .

As examples of further embodiments of the subject matter of the invention, it should be noted that it can also serve as a door closer, in which case one point on the door and the other point on the door frame fastened so that when the door is opened the tips are brought together; even as sugar tongs he can be trained by pressing the appropriately designed wings together hold the sugar lump on the tips. If a hook is used to hold the tips together, it can be the device as a clothes or letter clip ο. use.
