The invention relates to a door arrester, in particular for motor vehicle doors, in which in addition to the Limitation of the opening angle of the door, it is braked during its pivoting movement.

The invention is based on such door stops, which are essentially formed from a pivotably hinged to the door post, serving as a brake band, flat and stiff extension arm and from brake roller bodies that slide on the latter and are guided in guide shafts of a housing penetrated by the extension arm, which is attached to the door frame and penetrated by the extension arm Brake roller body be pressed elastically against the two width surfaces of the extension arm.
. It is known to achieve a braking effect when closing and opening a door in that braking bodies are designed as eccentric pressure pieces. In this known embodiment, rollers provided with a cam and resting on the two opposite broad surfaces of the raising arm are arranged, which are supported elastically resiliently by means of spring leaves. Here, the cams rest with one of their flanks on the surface of the extension arm. During the movement of the door, the extension arm slides between the brake rollers through the ., _T housing ^ so; drag the printing blocks over the extension arm surfaces. By sitting at the end of the arm. Stool - however, the rollers are partially rotated, and the other flank of the cams comes to rest against the extension arm surface, the: i cam being inserted behind the stool arching like a latching tooth. In this position, the door is adequately secured against slamming in its open position. During the opening and closing positions of the door, an equally large braking effect occurs in both directions, which is only dependent on the force of the springs supporting the rollers.

The invention is now based on the object of reducing the braking friction of the brake body in the entire BeWe-- ' The range of movement of the door is small in one direction of movement, but in the opposite direction of movement make very big. Experience has shown that this takes into account that the slamming of a motor vehicle door always takes place with considerably greater force than can be used to open it. For this The basic purpose of the invention is to provide a very strong braking effect only in the closing direction of the door to enable.

For this purpose, according to the invention, the guide shafts provided with a breast at their open end designed to run at an acute angle to the extension arm.

As a result, the compact design of the brake housing, for example by reinforcement, is without enlargement the spring support of the brake rollers, a door stop, especially for car doors

sufficient braking effect 'as a result of the automatic Clamping effect of the roles achieved.'Es is therefore in an advantageous manner z. B. also then the door in theirs opening position held; when the 'Wagen · iIj So far, experience has shown that the door is under the effect of its own weight

Furthermore, according to the invention, the door arrester achieves the occurrence of the clamping effect through automatic noiseless displacement of the brake rollers ^{. :-! I}

A simple one. ¹ DieVgedrungeheBauart due to ^{1 the} simplest components, resulting design is, as is known, achieved by! That. the guide shafts are formed by the walls of differently sized nested brackets, both of which are held by a single base plate, from the side edges of which tabs are bent up, which laterally close the housing formed by the bracket.

In order to make it easier to push through the brake band when attaching the door holder, according to the invention in the apex of each bracket through slots for the extension arm and provided by both narrow sides of the outer bracket slot lugs bent inwards, which the brake rollers when pulled out Keep the extension arm at a distance.

This avoids considerable wear on the passage slots due to the start-up of the brake band is, according to the invention of the narrow edges of the in the base plate for the passage of the extension arm provided slot bent inwardly lobes on which the narrow surfaces of the extension arm are starting to lead.

Claims (4)

1 . In the drawing, an embodiment of the invention is shown Err. It shows Fig. 1 the plan view. Fig. 2 a side view with the door holder housing cut open,: ■ ■ '■ Fig..3 the front view of the latter and .'Abb. 4 shows a section along the line A-B in FIG. 3. The door arrester consists essentially of an extension arm 3, which is pivotably mounted around the bolt 2 by means of the hinge bearing block 1 and used as a brake band, perpendicular to the plane of the door. The latter occurs through the. Brake housing 4 through and has a buffer 5 at its free end to catch the door. Over a more or less long distance in front of the buffer, the brake band is preferably provided with a well-known corrugation 6 protruding on both sides. The brake housing 4 is provided with guide shafts 7 and T- which have a breast 8 and 8 'at their open ends. In the guide shafts 7 and T, elastically supported brake rollers 9 and 9 'are arranged in a manner known per se on both flat sides of the deployment arm 3. Rubber pads 10 are used for elastic support. The guide shafts 7 and T run at an acute angle to the deployment arm or brake band 3 passed between the brake rollers 9 formed bracket, both of which are held by a single base plate 13. On the side edges of the base plate 13 tabs 14 are bent up (Fig. 4), which laterally close the housing 4 formed by the bracket or 16. On the narrow sides of the outer bracket slot 15, lugs 17 are also bent inwards, which keep the brake rollers 9 at a distance when the extension arm 3 is pulled out inwardly bent tabs 19, on which the narrow surfaces of the extension arm 3 starting to lead. If the housing 4 is moved relative to the extension arm 3 in its longitudinal direction, then, when this movement is in the direction of the arrow α (Fig. 2), the brake rollers 9 automatically jam, so that the brake friction is considerably increased. When moving in the opposite direction, however, the rollers will give way against the elastic support. This increased braking effect occurs particularly strongly and therefore advantageously at the end of the extension arm 3 when the rollers 9 run against the corrugation 6 and can exert an increased effect (cf. the dash-dotted illustration in FIG. 2). For claims 2 to 4, protection is only sought in connection with the main claim. Patent SPIUH-. HE: 1.Door holder, in particular for motor vehicle doors, which essentially consists of a pivotably hinged to the door post, serving as a brake band, flat and rigid extension arm and brake roller bodies that slide on this and are guided in guide shafts of a housing through which the extension arm extends, the braking roller bodies being pressed elastically against the two broad surfaces of the raising arm, characterized in that the guide shafts (7, T) provided at their open end with a chest (8, 8 ^) extend at an acute angle to the raising arm (3), 2: Door holder according to claim 1, characterized in that the guide shafts (7, T) are formed by the walls of differently sized, interlocked - "-. ■ Side edges flaps (14) are bent up, which laterally close the housing (4) formed by the bracket. 3.
