Description

The invention relates to a door handle for a door, flap, hood or the like on a motor vehicle with a mounting bracket and a handle whose bearing end is rotatably mounted on the mounting bracket and the operating end in an actuating opening of the mounting bracket protruding with an actuating transmission member, in particular in the form of a Bowden cable , a push or pull rod, a lever or the like is connected.

The DE 10 2004 061 092 A1 . DE 10 2007 049 900 A1 . DE 102 32 583 A1 . EP 1 556 596 B1 . EP 1026 351 B1 . EP 1 031 683 B1 and the DE 42 29 930 C1 show such door handles. For the storage of such a door handle on a motor vehicle door is a mounting bracket which is fixed on the inside wall side of the door panel. The door outside arranged handle has a bearing end, with which it is rotatably mounted on the mounting bracket with a hook-like bearing end. From the bearing end opposite end of the handle protrudes an actuating arm, which projects into an actuating opening of the mounting bracket. He is there via an actuating transmission member, for example via a lever mechanism or directly connected to a linkage or a Bowden cable to cooperate by pulling the handle in an operating direction with a lock.

The invention has for its object to simplify the assembly of the handle.

The object is achieved by the invention specified in the claims, wherein initially and essentially a guide slider is provided which is fixed in a pre-assembly position in which the handle is not yet connected to the mounting bracket on the mounting bracket by means of a holding means. The guide slider is already connected to the actuating element, for example to the end of a Bowden cable. The mounting bracket can thus be fixed to the door together with the guide slider and the Bowden cable attached thereto or a transmission lever or the like. The actuating transmission member may already be firmly connected to the guide slider before the attachment of the guide slide on the mounting bracket. It may together with the guide slide form a mounting unit, which is brought there in assembling the mounting bracket in a temporary holding connection. When mounting the handle on the mounting bracket, the handle enters into such firm connection with the guide slider that it will be taken along by a release of the holding means with which the guide slider is temporarily attached to the mounting bracket by the handle during its operation. The guide slider is immovably fixed to the actuating arm and thus performs the same movement as the actuating arm when the handle is pivoted. The guide slider effectively forms the end of the actuating arm and in particular those portions of the actuating arm with which the guide slider is guided as part of the actuating arm in the actuating opening. The connection of guide slider to actuator arm is preferably carried out by means of a hook connection. The guide slider may form a cavity flanked by two U-shaped legs. In this cavity, the mounting arm enters during the assembly of the handle. The U-legs can each form pairs of hooks which engage over counter-hooks of the actuating arm. At the end facing away from the handle of the guide glider can form a frame-like extension. In this is an end portion of the actuating arm. If a movement deflection, for example, of a Bowden cable is required, this can be done with a sheave. But it is also possible that the actuating element is formed by a reversing lever and the Bowden cable acts on the actuating element. The actuator can also be otherwise, for example. Of a push-pull rod, be formed. It is also possible to use a textile rope as an alternative to the Bowden cable. The pulley may be rotatably mounted on the mounting bracket and for this purpose form a bearing axis. Preferably, the sheave is motion-coupled with the guide slider. This is done via coupling elements. For example, a coupling pin of the guide slide engage in a coupling recess of the pulley. Further, a spring is provided, the spring force acts against the guide slider against the operating direction of the handle. If the handle is pivoted from its rest position by pulling on the handle, the spring is tensioned. The actuation of the handle thus takes place against the restoring force of the spring. The spring can attack directly on the guide glider. However, it is preferred that the spring acts, for example, in the form of a torsion spring on the sheave. The pulley may also be a carrier of a chamber for receiving a balance weight. The balance weight is located at the end of an arm of the pulley, which faces the coupling elements. The balancing mass is dimensioned so large that in a side impact, so when the door has a high lateral acceleration acting outwards, according to an acting on the balancing mass inertia force on the sheave torque is applied, which acts against the handle against its actuating direction. The torque acting on the pulley in the opposite direction due to the force acting on the handle inertial forces is therefore smaller. To stabilize the actuating arm within the actuating opening may form the latter sliding elements. These sliding elements protrude out of the walls of the actuating opening and may be rounded extensions. The extensions can, for example, form cylinder surfaces or spherical surfaces. Sliding surfaces of the guide slide slide along these sliding elements when the handle is operated. The mounting of the mounting bracket is done in several steps. First, the guide slider with attached actuating transmission member, for example. A Bowden cable, and the pulley attached to the mounting bracket. Then the mounting bracket is struck on the inside of the door. The attachment of the handle takes place in several successive steps. First, the bearing end of the handle is hooked into a bearing opening of the mounting bracket. For this purpose, the bearing end of the handle is formed like a hook. Then, the handle is pivoted counter to its actuating direction about the bearing end, so that the actuating arm enters the actuating opening, in which the guide slider is temporarily held by the holding means, which is a headband for a lock cylinder. The actuating arm is inserted into the actuating opening until the hooks of the guide slide lie at the level of the counter hooks of the actuating arm. Then the handle is moved transversely to its direction of actuation. It is a shift towards its end of storage. The hooks enter the hooks. Subsequently, the headband is moved. During this displacement, the retaining extensions of the retaining clip come out of the retaining recesses of the guide slider. The spring described above, acting on the sheave or directly on the guide slide then causes a slight displacement of the guide slide against the actuation direction of the handle, so that the hooks engage in the counter hooks. The spring pulls the handle to its rest position. The guide slider is now firmly connected to the actuating arm and, when the actuating arm is displaced in the actuating direction by pivoting the handle from the rest position to an actuating position, taken along.

The inventive door handle shown in the drawings has a mounting bracket 1 made of plastic. This can be fastened on the inside of the door panel of a motor vehicle door. It has a bearing opening 27 for storage of a storage end 3 an actuating handle forming a handle 2 ,

The mounting bracket 1 also has an opening 7 on, the handle length of the bearing opening 27 is spaced. This attachment opening 7 serves to accommodate an actuating arm 4 of the handle 2 and a lock cylinder, not illustrated in the drawings, or a filler piece of the same shape as a lock cylinder.

Inside the opening 7 is a headband 6 arranged. This is for mounting purposes transverse to the direction of extension of the opening 7 displaced. The headband 6 forms two spaced arms 32 out, the end with a bridge 31 connected to each other. The bridge has an internal thread 33 for screwing a fastening screw, not shown. To operate the fastening screw is an opening 34 in the mounting bracket 1 , The two free ends of the poor 32 form holding extensions 26 made with holding recesses 21 a guide glider 8th interact. They also form hook-like inwardly directed attachment projections 20 from, with which the above-mentioned lock cylinder or the above-mentioned filler in the opening 7 can be fixed.

The handle 2 consists of a plastic molding and has at one end the bearing hook 3 on that in the bearing opening 27 the mounting bracket 1 can be inserted and there acts as a grip bearing. At his the end of the camp 3 the end facing away carries the handle 2 the actuating arm 4 in the operating opening 7 the mounting bracket 1 protrudes. The actuating arm 4 has an end section 13 and between end portion 13 and root of the actuator arm 4 arranged hook cutouts 10 , These hook cutouts 10 make counter hooks for hooks 9 of the guide glider 8th ,

The guide glider 8th also consists of a plastic molding and has a substantially U-shaped shape. On both sides of a cavity 11 extend U-legs, the two hooks on its inside 9 exhibit. The two U-legs also form the hook recesses 21 in, in the pre-assembly, the holding processes 26 of the retaining clip 6 intervention.

The guide glider 8th also has a frame extension 12 , which is formed by two mutually parallel legs. The two thighs 12 are end over a bridge 13 connected with each other.

An end section 28 a Bowden cable 5 is stuck with the guide glider 8th connected. The end section 28 can in the production of the guide glide 8th in the plastic mass of the guide glide 8th be admitted. For example, it can be overmoulded. But it is also possible that the fastening end 28 of the Bowden cable 5 only in an opening made with a corresponding undersize of the guide slider 8th is pressed.

The soul of the Bowden cable 5 that are attached to the end of the attachment 28 connects, extends between the two frame extensions 12 and lies on a pulley 15 on.

The pulley 15 has a bearing axle, that of two axle stubs 16 is trained. The stub axles 16 are in corresponding bearing eyes of the mounting bracket 1 stored in such a way that the pulley 15 by a certain swing angle around the bearing axis 16 can pivot. The pulley 15 also owns a chamber 19 for receiving a balancing mass. The balancing mass 19 is sized so that in case of a side impact torque on the sheave 15 which is greater than the torque which is from the handle 2 is applied to the pulley. As a result, the handle is applied in the side impact against its actuation direction. This has the consequence that the side impact of the Bowden cable 5 not operated.

In a regular operation of the finished handle from the in 4 illustrated rest position in the in 7 shown actuating position pivots the handle 2 around the end of the camp 3 assigned bearing axis. The actuating arm shifts 4 and firmly with the operating arm 4 connected guide glides 8th inside the opening 7 , The fixed to the guide slider 8 Bowden cable 5 is pressed. As the pulley over one of the guide glider 8th protruding coupling pin 18 which is in a coupling recess 17 engages, with the guide glider 8th is motion coupled, the pulley rotates 15 upon actuation of the handle 2 around the bearing axis 16 With. During the movement of the guide glider 8th in the extension direction of the opening 7 glide the outer walls of the guide slider 8th , so in particular the outer walls of the U-legs 14 on sliding elements 22 . 23 from the wall of the opening 7 assigned. A dome-shaped sliding element 22 acts with a rear wall of the guide slider 8th together, in a stop cam 29 goes over, in the Betätigungsendstellung on a counter-stop 30 the mounting bracket 1 is applied. Two opposing cylindrical sliding elements 23 glide on the two facing away from each outer walls of the U-legs 14 from.

The handle is assembled as follows:

The 9 shows the door handle in a pre-assembly. In this pre-assembly is the guide glider 8th temporarily, ie detachable, with the mounting bracket 1 connected. The Bowden cable 5 is part of this assembly unit. His soul lies on the pulley 15 , This from mounting bracket 1 , Bowden cable 5 and guide glides 8th existing mounting unit is mounted on the inside of the door panel of a motor vehicle door. The other end of the Bowden cable, not shown 5 can then be mounted directly on a door lock to be operated. The guide glider 8th is in this pre-assembly of the headband 6 held. An unillustrated, in the threaded opening 34 Screwed screw holds the headband 6 on a position in which the holding processes 26 in the retaining recesses 21 of the guide glider 8th intervention. By a force applied in the engagement direction of the guide slider 8 is against the sliding member 22 or the sliding element 22 adjacent wall of the opening 7 pressed.

Only after mounting this assembly unit on the door is the handle with its end of storage 3 in the bearing opening 27 hooked so that in 9 achieved first handle assembly position is reached.

In a next step, the handle becomes 2 at the end of his bearing 3 pivoted in the direction of the arrow a, wherein the actuating arm 4 in the opening 7 dips. The actuating arm 4 is doing on the guide glider 8th moved past ( 10 ).

In another assembly step, in the 11 is shown, the handle becomes 2 in the direction of the arrow b relocated, leaving the hooks 9 the counter hooks 10 of the actuating arm 4 can overflow. This puts the operating arm 4 in the U-opening of the guide slider 8th , The actuating arm 4 lies form-fitting between the two U-thighs 14 and lies with its side walls on the inner walls of the U-legs 14 at.

The 12 shows the fully into the U-space of the guide slider 8th inwardly displaced actuating arm 4 before the final intervention of the hook 9 in the counter hook 10 ,

In this mounting position is by pressing the not shown, in the internal thread 33 screwed screw the headband 6 in the direction of the arrow c in 13 postponed. This is where the holding processes occur 26 from the retaining recesses 21 out.

The mounting of the handle 2 is thus essentially two stages. First, the handle is pivoted about its hinge axis until the hooks 9 a Einhakposition to the counter hook 10 taking. Then the handle 2 displaced linearly substantially transversely to the pivoting direction, the hooks 9 towards the counter hook 10 move. After loosening the temporary support of the guide glider 8th at the mounting bracket 1 then the hook engagement is completed.

The feather 25 that the guide glider 8th against the direction of actuation of the handle 2 impinges, shifts the guide glider 8th do so in the direction of the arrow a, leaving the hooks 9 in the counter hook 10 intervention. This is the handle 2 to the in 4 shown rest position entrained. In this position, the guide glides 8th permanently spring-loaded. The handle 2 is thus from the spring 25 kept in its rest position. Because this is about the guide glider 8th is done, the hooks 9 permanently in the direction of the hook engagement position in the counter hooks 10 applied.

If the handle - as mentioned above - from the in the 3 and 4 illustrated rest position in the in the 7 and 8th displaced illustrated operating position, so is the handle 2 the guide glider 8th dragged along and the Bowden cable 5 actuated. If the handle in the operating position according to 7 and 8th released again, so pivoted when operating the handle spring 25 the handle 2 back in the in the 3 and 4 illustrated rest position.
