Description

The invention relates to a motor vehicle door handle with a motor vehicle door assignable carrier, which is assigned a particular outside door handle, wherein the handle bar has a bearing end and a mounting end, and is fastened to the bearing end via a spring element pivotally mounted on the carrier, that a associated with the actuating end, immersed in an actuating opening of the carrier Zugstück is displaceable relative to the carrier.

Such a door handle is in the DE 32 31 210 A1 described. There, the bearing end of a handle strap is connected by means of a Anschraubböckchens with a carrier. Between handle and Anschraubböckchen extends a U-shaped spring element.

The DE 103 06 679 B4 describes a formed by a spring band centering, which also performs a pivot bearing function of a handle bracket.

The invention is based on the object to improve a motor vehicle door handle manufacturing technology.

The object is achieved by the invention specified in the claims wherein initially and essentially provided that the spring element is the connecting means between the handle and carrier and in particular a leaf spring strip having a first end on the carrier and with a second end at the bearing end of Handle is attached. The carrier can be fastened in particular to the inside of the door on a motor vehicle door. The outside of the door arranged handle bar is connected via the leaf spring strip to the carrier. The connection is made at the bearing end of the handlebar. The leaf spring strip thus forms a pivoting hinge for the handle. The spring element is preferably the only connection between the bearing end and the carrier. When the handle bar is pivoted about the hinge formed by the leaf spring strip, the leaf spring strip bends slightly. The operating end of the handle strap sets in the pivoting movement a path substantially transverse to the plane of extension of the motor vehicle door. At the operating end sits a pulling piece, which dips into the actuating opening of the wearer. With the Zugstück a door inside arranged in the region of the carrier locking device can be actuated. For example, a rotary latch lock can be opened via a Bowden cable, which holds the motor vehicle door in its closed position in a closed position and which is brought by train on the handle in a release position in which the vehicle door can be opened. It is further provided that the bearing end of the handle strap after insertion of the Zugstücks in the actuating opening by means of fastening means on the carrier can be fastened. As a result of this embodiment, the handle bar can be assigned during assembly first with its operating end of the carrier. During assembly, the pull piece is thus first inserted into the actuating opening. In this case, the handle bar relative to the carrier can be angled so that relatively long transversely to the direction of extension of the pulling piece projecting extensions can be inserted through the narrow actuating opening. The protruding substantially transversely from the Zugstück extensions have a transverse extension length, which is greater than the transverse opening width of the actuating opening. This has the consequence that very high tensile forces can be exerted on the handle. The ends of the transverse processes can strike at the door inside opening edges of the actuating opening with fully swung handle. The fastening means with which the bearing end of the handle can be secured to the carrier can be arranged at the second end of the leaf spring strip. The first end of the leaf spring strip can be firmly connected to the carrier. The carrier can be made of a plastic. Preferably, the leaf spring strip material is uniformly associated with the carrier and has at its second end, which projects freely into a bearing opening of the carrier, the fastening means. These can have two jaws. A jaw may be rigidly connected to the second end of the leaf spring strip. The movable jaw can be connected via bending film strip with the firmly seated on the leaf spring strip jaw. The jaws, which are spaced apart from each other, and the bending film strips form a shaft into which a clamping extension fixedly connected to the bearing end of the handle can be inserted. The assignment of the clamping extension to the fastening means takes place after the pulling piece has been inserted into the actuating opening of the carrier. In a variant of the invention it is provided that the clamping device, so for example clamping jaws, are arranged on the handle. From the freely projecting into the bearing opening end of the leaf spring strip then protrude from an extension which can be fixed by means of the clamping device at the bearing end of the handle bracket. In the preferred variant, in which the jaw assembly are associated with the free end of the spring element, can protrude from the freely projecting into the bearing opening spring element and in particular of the clamping device transverse processes, which have as well as the projecting from the Zugfor Querfortsätze a transverse extension length which is greater than the transverse extension length of the bearing opening, so that these transverse extensions strike against the inside of the door against the edge of the bearing opening, if a high tensile force on the handle is exercised. In a further development of the invention it is provided that the pull piece is coupled with a handlebar.

The handlebar may have two link arms, which are rigidly interconnected by means of a shaft. The shaft is pivotally connected to the carrier about a carrier-fixed pivot axis. The links themselves are connected to the protruding from the Zugstück extensions.

An embodiment of the invention will be explained below with reference to accompanying drawings. Show it:

The door handle shown in the drawings has a carrier 1 , which in particular can be fastened to the door skin on the inside of the door. In the drawings is the carrier 1 shown as a molded plastic plate. He can below the handlebar 2 have a recessed grip.

The carrier 1 has at its one end a bearing opening 22 , in the one material with the carrier 1 connected extension protrudes in the form of a leaf spring strip. A first end 5 ' of the leaf spring strip 5 is fixed to the edge of the bearing opening 22 connected. Parallel to the opening plane of the bearing opening 22 the leaf spring strip protrudes 5 in the storage opening 22 into it, that the free end 5 '' freely located in the bearing opening.

At the free end 5 '' of the leaf spring strip 5 is a jaw 9 attached. The jaw 9 is rigid with the second end 5 '' connected to the spring element. This firm jaw 9 is over bending film webs 12 with a movable jaw 10 connected, which are parallel to the fixed jaw 9 extends. Between the fixed jaw 9 and the movable jaw 10 there remains a shaft 11 , whose narrow shaft walls from the bending film strips 12 are formed. It is a clamping screw 13 provided, which are transverse to the extension of the shaft 11 in an opening of the jaw 10 can be put into it. The thread of the clamping screw 13 can into a threaded opening of the fixed jaw 9 be screwed.

The two jaws 9 . 10 protrude inside the door on the base plate of the carrier 1 out. There may protrude in the drawings, not shown Querfortsitze whose transverse extension length is greater than the transverse opening width of the bearing opening 22 , The leaf spring strip 5 forms a hinge axis around the handlebar 2 is pivotable. Will be on the second end 5 '' of the leaf spring strip 5 applied a very large tensile force, so the transverse processes, not shown, can strike against the underside of the support plate, so that high tensile forces on the handle 2 can be applied.

The end of the warehouse 3 of the handlebar 2 has a fixed to the handle 2 connected clamping extension 8th , The terminal extension 8th can the same material handle the handle 2 be formed. The terminal extension 8th can between the two jaws 9 . 10 be plugged. By tightening the clamping screw 13 becomes the terminal extension 8th firmly between the two jaws 9 . 10 trapped.

The other end of the carrier plate of the carrier 1 has a cutout T-shaped actuating opening 6 ,

The end of the operation 4 of the handlebar 2 has a pull piece 7 on whose end transverse processes 14 formed. The transverse processes 14 protrude in a T-shape from the Zugstück 7 from. The Zugstück 7 extends substantially parallel to the terminal extension 8th and can also be made of the same material from the handle 2 be educated. The two ends 14 ' of the transverse processes 14 have a distance that is the transverse extension length of the transverse process 14 Are defined. The latter is greater than the transverse opening width of the actuating opening 6 passing through the two surface elements 6 ' and 6 '' is determined.

From the back of the carrier plate of the carrier 1 protrude two Lagerböckchen 20 off, each a bearing eye 21 form, through which an axle pin 19 can be plugged. It is a handlebar 15 provided with a hollow handlebar shaft through which the axle pin 19 is pluggable to the handlebar shaft of the handlebar 15 at the Lagerböckchen 20 to hinge.

On a shaft extension of the bearing shaft sits a leg spring 18 to the handlebars 15 with a Apply torque to the handle bar 2 in its normal position ( 4 ) holds.

The driver 15 is via handlebar arms 16 with the handle 2 connected. The handlebar arms 16 are parallel and spaced from each other and form at their free ends snap openings 17 out, in which the free ends 14 ' of the transverse processes 14 can intervene.

The assembly of the handlebar 2 takes place in several consecutive steps. First, the handlebar 2 in such a tilted position to the base plate of the carrier 1 brought that, then obliquely to the opening plane of the actuating opening 6 extending extensions 14 through the actuating opening 6 can be angled. Subsequently, the handle bar is brought into the untilted position, in which the free ends 14 ' of the extensions 14 in the snap openings 17 be introduced. Subsequently, the clamping extension 8th in the clamping shaft 11 between the two jaws 9 . 10 plugged in. Finally, the clamping screw 13 dressed so that the end of the warehouse 3 firmly with the leaf spring strip 5 connected is.

Applying a tensile force to the grip handle on the fully assembled handle 2 Applied, so the handle bar shifts 2 from the in 4 shown normal position in the in 6 shown pivoting position. In the course of this pivoting is the Zugstück 7 through the actuating opening 6 relocated. The driver 15 is pivoted. With a Bowden cable, not shown, a linkage, not shown, or with other transmission means, this pivotal movement can be transmitted to a door lock to open it. In the course of the pivoting movement of the leaf spring strip 5 slightly bent.

It is considered advantageous that the order of assembly can be reversed according to the innovation over the prior art. First, the rearward facing end of the handle is mounted in the direction of travel, which is the T-shaped extension 7 . 14 having. In which the extension 14 wider than its associated Einfädelöffnung 6 Must be the handle 2 slightly tilted during assembly, which is possible because the end of the bearing 3 not yet with the carrier 1 connected is. Another advantage of the innovation is the freedom of the handlebar 2 seen both in the direction of travel and in the vertical direction. This results because of the rigid mounting of the bearing end 3 on the carrier 1 , In addition, the novelty brings the advantage that pull-out forces on the handlebar 2 are applied over the transverse processes directly into the carrier 1 and thus can be introduced into the door panel.
