EMIL DIETERLE in CHEMNITZ-GABLENZ.

Patented in the German Empire on March 2, 1913.

The previously known door closers, in which the closing of the door on the more or less large tension of tension or spiral-wound leaf springs is based, and their tension by means of any, in Guides sliding rod connections came into effect, made the Ubelstand noticeable that in the mutually shifting means the lubricating

ίο Material used up or stripped soon and an uncomfortable, even very annoying one, due to the drying out only too soon Noise was generated, which also changes with each opening and closing of the door, like expected otherwise, repeated.

The novelty of the invention consists in the fact that a rocking angle lever is mediated a roller arranged on its angularly bent part constantly with the train of one or more springs one that is partially turned over when the door is opened by the lock arm and has a notch provided disc is held in contact.

Because the tension of the springs, which increases when the door is opened, then acts on closing the door, achieved by swinging and rolling intermediate means a quiet and noiseless closing of the door is achieved because As is known, the lubricating material is in closed bearings suitable for rotation gets better.

It show in the drawing:

Fig. Ι and 2 a door closer according to the invention in two views, namely in the position with the door closed,

Fig. 3 in plan view and in the position with the door open by 90 ° and

4 shows the door closer, attached to a door, on a reduced scale.

In the housing α pressed or cast from sheet metal, an angle lever f is pivotably mounted on the bolt k.

This angle lever is pressed in the embodiment from a piece of sheet metal but also made of any other suitable material and in a different shape can be.

The angled part e of the lever f is equipped with a roller d , while its free end carries a web h which, sliding in guides m , can be moved by a screw i.

The ends of the web h protruding on both sides of the guides m serve to attach the springs g, which in turn are pushed onto pins 0 with their eyelets bent on the other side, which are arranged flat on a disk c .

The disc c itself, which is assumed to be known and is rotatably mounted in the same housing a at an appropriate distance from the angle lever, is provided on its circumference on the one hand with a notch I and on the other hand carries the locking arm b.

Claims (1)

The springs g cause the roller d to be kept in constant contact with the disk c. The effect is as follows: When the door is closed, the roller d is at the angle lever end e as a result of the tension of the springs g in the notch I of the disc c (Fig. Ι and 2) and the arm b is pressed against the pin η attached to the door (Fig. 4). The pin η is only provided to protect the door, since the arm b can also be bent accordingly, so that it then rests directly against the door in a pressing manner. When the door is opened, the pin η causes the disk c to rotate in the direction of the arrow A by means of the arm b , whereby the roller d is first pushed out of the notch I and the angle lever swings into the position of FIG. 3, in which it swings while the door continues to open and the disc c continues to rotate, the roller «! on the now circular circumference of the disc c rolls. If the springs g have already been tensioned initially during this opening process of the door, then with the door opening more and more and the disc c rotating at the same time, a steadily increasing tension occurs, through which the roller d with the greater Force is pressed onto the periphery of the disc c and thereby a greater inhibition is brought about, but this is not noticeable when the door is opened due to the rolling of the roller d on the circular periphery of the disc. Fig. 3 shows e.g. B. the door closer position with a door opening of 90 °. When the open door is released, the springs g tensioned with the opening of the door cause the disc c to rotate in the direction opposite to the direction of the arrow A and thus to close the door, in fact only at a moderate pace, because the roller d is pressed against the circular circumference of the disc c there is enough inhibition. At the end of the closing movement, the roller d then re-enters the notch I of the disc c , so that the door is securely pressed into the lock by the rapid relaxation of the springs g that occurs as a result. The tension of the springs g can be regulated according to the position and gravity of the door in that the springs g can be tensioned according to the respective desired tension by the web h which carries the same and which can be displaced by the screw * 'in its guides m. It should be noted in this regard that the adjustable tension of the springs g through the displacement of the web h in its guides m by means of the screw i does not form part of the invention. If, in the exemplary embodiment, two springs g are arranged, one on each side of the disc c and the angle lever, then only one spring of the appropriate clamping capacity needs to be arranged in the middle of the angle lever and the disc c, with which the same effect is achieved than with two springs, which arrangement is readily, as understandable, not shown in the drawing. - Godfather τ-An saying: Door closer with spring tension, and by means of the lock arm partially convert rotating, provided with a notch disc, characterized in that a bearing supported on the door jamb angle lever (f) by one or more tension springs (g) is connected to the part by the locking arm (b) convert the rotating disc (C ) that a roller (d) provided in the angled part (e) of the lever (f) is kept constantly in contact with the disc '(c). . 1 sheet of drawings.
