Door stops, in particular for motor vehicle doors

The invention relates to a door arrester, in particular for motor vehicle doors, in which one on a door assembly part door or door pillar, hinged Door holding rod with its free end in an elongated holder housing attached to the other door arrangement part immersed and at the bottom of which is supported by at least one roller and in which the door holding forces during passage the support role of the door support rod through the interaction Brake ramps and locking cams arranged on the holder housing with at least one on the door support rod or its support roller acting loading spring, which can optionally be designed as a torsion bar spring, are applied.

In a known door arrester of this type, an axis parallel to the hinge axis of the door emerges a door support rod hinged to a door assembly part elongated, in cross-section U-shaped, on the other door assembly part a hinged holder housing and is supported on the bottom of a pair of rollers. The dem Roller tracks of the holder housing assigned to a pair of rollers have upward braking ramps and Brake cams are provided, while the pair of rollers has a simultaneously bearing a centrally arranged brake roller forming axis is mounted on the free end of the door holding rod that plunges into the holder housing.

centrally arranged brake roller acts the lowest Peaer- "sheet of a leaf spring assembly clamped at the end of the holder housing opposite the inlet opening for the door support rod in such a way that the outer rollers are provided with braking ramps and brake cams by the force of the load through the leaf spring assembly The leaf spring package dips into the upwardly directed profile opening of the holder housing and is bent over with respect to its lowest spring leaf, which interacts with the brake roller, in the area of the brake ramps and brake cams provided in the raceways of the rollers against the housing base Mn This is intended to achieve a greater spring loading of the rollers towards certain sections of the roller tracks erpaket and the formation of the braking ramps and locking cams in the raceways of the rollers at certain door opening angles increasing braking forces or holding forces are generated, which brake the door over certain opening angle ranges and can hold it in certain opening positions. Usually, the brake ramps and brake cams of the holder housing are designed and arranged so that the door is first braked in two different opening positions and then held in place with a certain force, the handles having to be dimensioned so that the door can be opened further with moderate use of force can. Achieving a desired braking and holding characteristic of the door over a certain opening angle range requires, in addition to a corresponding design of the braking ramps and holding cams, a suitable dosage of the loading force to be applied by the loading spring over the respective roller track section. In the known application of a leaf spring assembly, a uniform distribution of the spring force is achieved with several successively arranged braking ramps and locking cams

Load spring not possible or only possible with a disproportionately high effort, so that this known type The disadvantage of door arresters is that "different opening angles of the door Holding forces are applied, with the smaller door opening angle the larger braking and holding forces fall. What is desirable, however, is a distribution of the braking and holding forces in such a way that the smaller door opening angle lower braking and especially holding forces are applied than with the larger door opening angle. In addition, the use of a leaf spring assembly as a loading spring for the Rollers are one for mass-produced parts, both in terms of production and the cost of materials and assembly very high manufacturing costs.

The invention is therefore based on the object of a door arrester of the type described in the introduction in such a way that with the least possible manufacturing effort at least two brakes or latches of the door assigned to each narrowly limited door opening angle the braking and latching forces associated with the smaller door opening angle at least not are greater than the braking and latching forces associated with the larger door opening angle.

According to the invention, this object is essentially achieved in that the transmission of the forces of the loading spring on the door support rod or its support roller at least over the area of the braking ramps and locking cams reaching out into the profile of the holder housing Pressure distribution member is assigned on which the supported in a manner known per se against the holder housing Loading spring engages in the region of the end of the holder housing which has the entry opening for the door holding rod.

The pressure distribution member is according to the invention by a preferably at that of the inlet opening for the Door support rod opposite end of the holder housing

Articulated, rigid rocker is formed whose Anlenkacb.ee on the holder housing is arranged at least approximately by the height of the support roller of the door holding rod or a brake roller arranged between a pair of support rollers above the general plane of the housing bottom .

According to a preferred embodiment of the invention , the brake ramps and east cams are formed on the holder housing and the rocker arm forming the pressure distribution element is cut to size by a smooth-surfaced flat or other profile material provided at one end with a hinge eye for articulation on the holder housing , or a cast part, in particular pressure - Or injection molding formed.

Another preferred embodiment of the invention can be provided that the holder housing formed by a simple U-shaped sheet metal housing and the pressure distribution member on its underside facing the smooth-surfaced housing base with locking cams and braking ramps is provided. In this Palle it is Pressure distribution member preferably by a deformed perpendicular to its plane and thereby with braking ramps and Locking cams provided profile, in particular Ilach material cut shown,. . The pressure distribution element can also have any other suitable profile cross-section have and in particular be formed by a casting, in particular a pressure or injection molded part. Regardless of the chosen form of the holder housing "or the pressure distribution element as well as the loading spring assigned to this can be used in all those cases in which the door retaining rod is over zv / ei lateral rollers against the raceways of the holder housing is supported and cooperates with the pressure distribution member via a centrally arranged brake roller this be made relatively narrow, so that its width is much smaller than the track distance and thus the holder housing in general.

According to a preferred embodiment of the door arrester according to the invention, the ^{load spring assigned to the "1st} pressure distribution element is formed by a torsion bar spring which is arranged and supported opposite the articulation point of the pressure distribution element in the area of the holder housing that has the inlet opening for the support rod , in particular formed a Z-shaped or C-shaped bent spring wire blank and supported via its bracket part on upwardly directed tabs of the holder housing side walls, with one of its free legs fixed in a bore recess on one holder housing side wall and secured against transverse displacement, above its other free, the 3elastungsschenkel forming leg is supported on the top of the pressure distribution member.

It is true that the application is already quite general due to its own older proposal (patent application P 24 15 0I8.3) of torsion bar springs for surf locks here in The type in question has been proposed, but this earlier proposal relates to an arrangement in which the Door holding rod having at least two rollers arranged at a distance from one another in the longitudinal direction Roller carriage is supported in the holder housing and in which the torsion bar spring continues directly between the Brake rollers arranged on rollers acts together. In this one belonging to a different type of door arrester Design result in relatively steeply increasing force peaks of the holding forces, which are not for everyone Application of such a door arrester are desirable.

Bach can another embodiment of the invention be provided that the pressure distribution member regardless of its training and regardless of the design of the Holder housing in which the entry opening for the door holder
