If you want to prevent the door from closing, use a simple armrest in front of it. More advanced devices include a wedge, which is usually made of rubber material in addition to wood, and a pin that is attached to the door and presses its head against the floor, thus locking the door in place. The downside is that when the door moves slightly out of the prop, the prop usually collapses and then the door can close without hindrance. The use of the above-mentioned restraining devices usually requires bending, which makes their use difficult.

The door holder according to the present invention eliminates said disadvantages. It consists of a door-based door holder fixed to the door by a pivoting shaft at one end, characterized in that the end of the holder contacting the base has a hook-like shape by locking it in a latch made therefrom and in fact the latch consists of two parts. a press plate which presses the holder upwards, 2 58198 whereby the hook-like end remains behind the tongue, the Ranko body and the press plate being vulcanized together, e.g.

The accompanying figures show an embodiment of the invention.

In Fig. 1, the stand 1 is in the operating position, whereby it rests on the door 3 and at its lower end 4 on the base through the fastening point 2, thus preventing the door from closing. When the door is possibly opened more, the boom 1 immediately follows the efforts to close the door.

In Fig. 2, the stand 1 is raised, e.g. with the foot, to the storage position _ up against the door, in which position it remains because the distance of the center of the fixing pin 2 from the door 3 is greater than the distance of the center of gravity 5 from the door. The prop is brought to the operating position by swinging the door quickly, whereby as a result of the continuity of movement the prop oscillates out of the door and falls around the pin 2 down into the actuator (Fig. 1).

Fig. 3 shows a holder provided with a hook-like end 11 which locks in the latch 13 shown in Fig. 4, in which a cam 8 corresponding to the hook 11 is bent on the body plate 7, behind which the hook 11 of the holder 1 is pressed, pressing the press plate 9 under the soft rubber 10 when springing. Removal takes place, for example, by pressing the holder 1 with the foot, whereby the hook 11 disengages behind the cam 8 and at the same time pushing the door.

Claims (1)

58198 Claim A self-acting door holder (1) pivotally attached to a door at one end by a shaft (2), characterized in that the end (12) of the holder (1) contacting the base (6) is hook-shaped (11) locking to a latch (13) fixed to the base , consists essentially of two parts, a body (7), the locking of which behind the tongue (8) takes place, and an oblique pressure plate (9) which presses the holder (1) upwards, the hook-like end (11) remaining behind the tongue (8) and the body (7) and the pressure plate are vulcanized together, e.g. with rubber (10), which provides the necessary pressure between the pressure plate (9) and the body (7) to lock the holder (1) and prevents debris from entering the device.
