Door stops for car doors

The innovation relates to a door holder for car doors with a pivoting, hinged to the door post, protruding through an opening into the interior of the door and into a brake and guide housing arranged therein Extension arm, in which the free end of the extension arm, designed as a buffer, slides in the housing in a manner known per se is performed, but the housing by connecting the hat-shaped folded flanges of a sheet metal rail of TJ-shaped Cross-section is formed with the door inner wall and on the opposite wall of the door of the housing on a Place that is far away from the articulation point of the extension arm, a steel spring leaf is attached so that it approaches the inside wall of the door like a ramp.

A well-known door holder keeps the weight of the door open against the effect of gravity. To that end is a Helical spring supported in a housing which is attached to the front wall of the door and at the same time to the door inner wall. The extension arm reaches through the helical spring and is at the end of the cabinet furthest from the door jamb slidingly guided. The door holder closes the door or opens it completely. He does not allow an intermediate position

It is also known to have a door stop whose extension arm is on at its end Hollen bears on the ramps of the lock housing run and spread a U-shaped steel spring over a plastic ring when the door is opened.

In the case of another door holder, the end of the extension arm is guided over lobes in the rails of the housing and it lies an equiaxed roller arranged in between on a steel leaf spring with detents, which this when opening the door tense.

The last two brakes described are on the front wall arranged by the door. The leadership of the Ausstellarmendes has the advantage that next to the housing in the door interior space for a retractable disc, but the housings are cast and the brakes are on during final assembly Assembly line screwed on as a complete unit.

In a known door arrester, the extension arm pivots over practically the entire area of the inside width of the door, so that there is no room for a crank window. The housing is attached to the front wall of the door adjacent to the door post.

A window stay is also known, the extension arm of which with its free end is embedded in the window frame Protective sleeve out and is pushed into this protective sleeve when the window sash is closed. The extension arm has like this

a certain swivel range and e.g. not the attachment obstruct a blind. In this window stay, the extension arm is bent considerably, so that reliable work is called into question.

Finally, the French patent 822 024 is known in which the free end of the extension arm between the Door inner wall and a spring clamped on one side is guided, which approaches the inner door wall at its free end.

The task of the innovation is to increase the durability of the steel spring leaf to increase the resistance of the steel spring leaf, which it opposes to the buffer on the extension arm when the door is opened, to make it more effective.

The innovation according to the solution is that the ramp-shaped Steel spring leaf at both ends on one wall of the housing is riveted and roughly at the point where the ramp comes closest to the inner door wall, between the steel spring leaf and a rubber pad is disposed on the wall of the housing. Instead of high-quality spring steel, the steel spring leaf can be used then manufacture r.us case-hardening steel. Next is the resistance that the buffer passes through as the door is opened more and more the ramp is opposite, enlarged by the rubber cushion and finally the force with which the door is in the The open position is held larger than when using the steel spring leaf clamped on one side.

A further development of the innovation can consist in that the rubber cushion is clipped into a recess in the wall of the housing.

The drawing shows an example of an embodiment of the furnace,

Fig. 1 is a section through part of the post, through the door hinge and through part of the door

the door holder,
Pig. 2 shows a detail from FIG. 1,
Pig. 3 shows a detail from FIG. 1 in a perspective illustration.

A door holder 2 is attached to the motor vehicle door 1, its extension arm 4 around the articulation point 5 on the door post 3 is pivotable. The extension arm 4 protrudes through an opening into the interior of the door 1 and the brake and brake lever arranged therein Guide housing 7j includes the extension arm 4 with the buffer is sliding. The housing 7 is screwed on the hat-shaped beveled flanges 9, 10 (Fig. 2) a Sheet metal rail 11 formed with a U-shaped cross section with the door inner wall 12. On the opposite of the door inner wall 12 Wall 13 of the housing 7 is a steel spring leaf 14a at a point which is far away from the articulation point 5 riveted. The other end of the steel spring leaf is also riveted to the wall 13. The steel spring leaf 14a approaches the inner door wall 12 like a ramp and moves away shortly before the point at which it is riveted to the housing 7

is, again from the door inner wall 12, so that a paragraph 16a arises.

The extension arm 4 comprises the cylindrical central part 17 of the Buffer 8. On both sides of this central part 17, collars 18, 19 are connected, which are wider than the central part 17. With their outer surfaces, the collars rest on the steel spring leaf 14a and on the wall 19a of the housing 7. Between the At the highest part of the ramp of the steel spring leaf 14a and the wall 13, a rubber cushion 15a is clipped into the opening 16b.

When the door is opened, the buffer 8 slides on the spring leaf 14a along, wherein a frictional resistance increases increasingly due to the ramp shape of the steel spring leaf. If the buffer 8 is at the level of the cushion 15a, then it has reached the highest point of the ramp and its frictional resistance stand no longer increases, but slides with further opening of the door with its rear wall 8a in the paragraph 16a and locked in this position the door. When closing the door, a relatively large resistance must first be overcome, if the buffer 8 with its rear wall 8a overcomes the shoulder 16a and thereby compresses the rubber cushion 15a. When the buffer 8 has slid over the highest point of the ramp of the steel spring leaf 14a, its braking resistance decreases.
