Description

The invention relates to a door lock for folding doors on motor vehicles.

The door lock serves to lock a door leaf, which is fastened in a conventional manner by means of hinges preferably on a D-pillar of a motor vehicle for opening and closing the rear side of the motor vehicle. The lock should have the simplest possible structure of as few components as possible, ensure a secure locking of the door leaf in a 90 ° position, even under unfavorable conditions and finally the longest possible service life.

Current door retainers are, for example, from the DE 195 47 321 known. This door arrester has a locking lever mounted on the door-side hinge part, which interacts with blocking bodies on the frame-side hinge part. The locking bracket is this pressed by spring force on the locking body, which has pockets for locking the door to accommodate the locking bracket at a 90 ° position and a 180 ° position. When opening the door of the locking bar runs under spring force on the locking body and locks at the predetermined opening position of the door in a pocket. To release the finding of the locking bracket must be lifted manually out of the bag.

These door retainers are disadvantageous. Since the locking bodies are formed of narrow webs, they are engaged with only a small portion of the locking bracket. This results in a high wear on the portion of the locking bracket and an insufficient detent. Furthermore, a manual intervention in the locking device for releasing the detent is necessary, which on the one hand represents a significant risk of pinching for the operator and on the other hand, with regard to the simplest possible operation is not a satisfactory solution.

From the DE 34 35 009 A1 a door lock for doors on motor vehicles is known in which a two parallel and at the end connected by a bar rods having headband is pivotally mounted with the free ends of the rods to a mounted on the body bearing part and with the web at the other U-shaped end Hold the door in its 90 ° position. For this purpose, the web of the strap end at the end of the opening movement of the door in the openings of two fishing hooks formed on a U-shaped sheet metal part and are screwed at a distance from each other by means of angled hook feet on a stiffening plate of a housing-shaped reinforcement of the door. Between the fishing hook, a U-shaped clamping member made of sheet metal below the hook openings is rotatably mounted on the fishing hook, which extends from the fishing hooks with a sliding and guide surface through the stiffening sheet and is supported there by a coil spring in the housing-shaped reinforcement is arranged between the clamping member and a base mounting plate which extends from the fishing hooks integrally therewith in the box-shaped reinforcement.

When opening the door slides the web of the U-shaped end of the retaining clip under the spring pressure of a leg spring in the bearing part on the sliding and guide surface of the clamping member until it falls into Rastierungsöffnungen, each on one side of the two hook openings and on the other Side of arcuate depressions of the clamping member are formed.

Therefore, the object is to provide a door lock, in which no manual intervention is necessary, which allows easy handling, ensures safe locking in a compact design and has the longest possible service life, namely as little wear as possible.

According to the invention, the door arrester thus consists of a base plate, which is fastened to a corresponding point of the body, for example. On a D-pillar, and thus forms the frame-side basic element of the door arrester. For attachment to the vehicle body, the base plate may have recesses for fastening means, conceivable are, for example, holes for screws. Other fixings such as by welding, soldering, riveting and clamping are also conceivable. Arranged transversely on the base plate is the frame part which is fastened to the base plate. An integral shaping of the base plate with the frame part is possible. The attachable to a door bearing part of the door arrester may also have recesses for fastening means. Again, other fasteners are conceivable. The headband serves as a connecting element between the door-side bearing part and the frame-side parts of the door arrester. The headband is suitably designed so that it withstands the forces occurring during the movement or detenting of the door leaf. Preferably, the mounting of the retaining clip on the bearing part is designed so that it works reliably even with a high number of operating cycles. The leadership of the retaining clip on the component is designed so that a uniform opening and closing of the door is possible with little effort. The guide can be formed by a sliding guide, roller guide or similar suitable guides. The arrangement of the component on both sides of the base plate is a long guide for the headband at low

Installation dimensions between door and body part possible.

The frame part is attached as a support of the component to the base plate and has an inner portion and an outer portion. With this embodiment, the stability of the construction and in particular the guidance on the component is increased. The inner portion is in this case arranged on the side of the base plate, which faces away from the door. Preferably, this portion of the frame part is located in a designated cavity of the body, for example. In a recess of the D-pillar. The outer portion of the frame part is arranged on the side of the base plate, which faces the door.

The component has a track for the headband. With this embodiment, the headband can, for example, be performed slidingly or rolling on the track, whereby a cost-effective guidance is achieved. Preferably, the track is wear-reduced, for example. By a suitable surface treatment.

Suitably, the track is formed substantially smooth surface and passed through the plane of the base plate (claim 2). The smooth surface formation ensures a uniform opening and closing movement, wherein the track is adapted to the movement path of the retaining clip. The arrangement of the track through the plane of the base plate through a very compact design is achieved. The headband is preferably designed so that it is largely closed door leaf on the inner side of the base plate. When the door leaf is opened, the retaining clip is then guided on the track until it is locked in the latching element in the open position of the door leaf.

At the outer end of the frame part the Rastierungselement is arranged. This is advantageous because the Rastierungselement, depending on the design, may be subject to regular maintenance. By this arrangement, the reaching of the Rastierungselements without disassembly of the door arrester is possible. Is it furthermore necessary to open the door wider than the predetermined Rastierungsposition allows this, for example. When loading the vehicle with a forklift, so it is possible to easily reach the Rastierungselement from the outside and the hinged door manually from the detent to to solve. Due to the arrangement at the outer end of the frame part, a long guide path of the retaining clip is further given to the detent.

The fishing hook is part of the Rastierungselementes. The fishing hook is a reasonably manufactured Rastierungselement that withstands larger forces.

The fishing hook has a formed with the frame part sword, which continues in a located on the other side of the base plate projection. The sword and the projection are formed integrally with the frame part, wherein the base plate has a recess which serves to receive this arrangement. It would also be conceivable, however, a multi-part design, the sword and the projection are each attached to the base plate. In both cases, an attachment may be formed by common attachment means, such as e.g. Screws and rivets. Preferably, however, the elements are secured by welding to the base plate.

The headband has a contact element which is guided on the track and is in the open position of the door leaf with the Rastierungselement engaged. This makes it possible to design the contact element subjected to wear by the guide in such a way that it can be exchanged if necessary. Also, the contact element can be formed so that it has good Rastierungseigenschaften so that the door, for example. By a gust of wind, not accidentally released from the detent.

The headband consists of two arms whose door-side ends are connected to the bearing part and the frame-side ends are connected by a web. In this form, the headband can be easily produced, for example. By a curved round steel. The headband also has by the arrangement of two arms high stability. Suitably, the contact element is arranged on the web of the retaining clip (claim 3).

According to an advantageous embodiment of the invention according to which the headband is guided on the track under spring pressure, the headband is under spring force with the Track kept in contact (claim 4). Due to the power support of the retaining clip a uniform contact with the track, regardless of the installation position of the door arrester, given, creating a safe operation is guaranteed. Preferably, the spring force is generated by one or more acting between the bearing part and the headband torsion springs (claim 5). The leg springs form low-maintenance and inexpensive spring elements that can be easily mounted between the bearing part and the headband. The arrangement between the bearing part and headband is therefore advantageous because the leg springs can be reached there without further disassembly of the door arrester.

The free end of the component together with the catch hook the Rastierungselement. By this structure it follows that the headband is also performed at the detent. The free end of the track of the component forms with the catch hook the Rastierungselement such that the contact element is also in running into the Rastierungselement exclusively with the track in contact. In a wear-reduced design of the track, the wear reduction is thus also given in the detent.

The locking element has a spring clip and is designed to receive and hold the retaining clip in the open position of the door leaf. The spring clamp is particularly cost-effective and enables reliable locking. Preferably, the spring clip is arranged in the catch hook.

Preferably, the track for the headband from an elongated hook spring (claim 6). The hook spring is preferably made of spring steel and has at its free end a hook, preferably designed as a hook spring clamp. Such a spring clip is arranged in the catch hook and thus serves to receive and hold the retaining clip. Thus, a resilient clamping of the retaining clip can be achieved in the open position of the door leaf, wherein the catch hook of the Rastierungselements can serve as a stop against tensile forces on the door.

In a preferred embodiment of the invention, the contact element is a plastic extrusion (Claim 7). The contact element may be exposed by the constant engagement with the component heavy wear. A plastic extrusion is an economical solution for reducing wear. Preferably, the contact element consists of a plastic-encapsulated sliding guide bushing (claim 8). The additional storage reduces wear on the contact element.

Alternatively, in another embodiment, the contact element is formed by one or more rotatably mounted on the headband Rastierungsrollen (claim 9). Suitably, the Rastierungsrolle made of metal, preferably made of steel (claim 10). Alternatively, other materials are conceivable, such as e.g. Plastics, preferably abrasion-resistant plastics, or ceramics. Material combinations, such as, for example, a steel roll with plastic coating, are conceivable.

On the arms and / or on the web of the retaining clip, in particular at the transition areas between the arms and the web, plastic body are arranged, and the frame part or the component has in the region of the catch on sliding plates, with the plastic bodies at the inlet of the web of the Holding bracket cooperate in the locking element so that the contact element is lifted from the track when entering the locking element. By this arrangement, the wear on the contact element of the retaining clip is further reduced. When the contact element enters the detent element, it engages with the raceway and is locked in the detent element, as a result of which the contact element engages in at least two places. Due to the arrangement of the plastic body and the sliding plates, the contact element is lifted from the track and stands when entering the locking element only at one point with the spring clip into engagement. By reducing the contact points at the inlet of the contact element in the Rastierungselement a significant reduction in the wear of the contact element is given. The contact element comes when entering the locking element with the raceway opposite part of the Rastierungselements namely with the spring clip, into engagement. The plastic body cause an increase of the contact element against the raceway against the spring force. As a result, the contact element is pressed into the detent position in the detent element, whereby the headband is held in the detent element.

According to an advantageous embodiment of the invention, the web forms an axis on which at least one Rastierungsrolle is arranged as a contact element which comes into engagement with the spring clip (claim 11). The Rastierungsrollen can thus be advantageously formed according to their function. Conceivable, of course, is only a role that is adapted according to their interaction with the spring clip.

Fig. 1 is used to understand the assignment of a door arrester in the region of a D-pillar 1 and a rotatably connected to the D-pillar by at least one door hinge 3 door leaf 2. The illustration is purely schematic. It is not to scale. Nevertheless, the basic structure of the door arrester, as will be apparent from the following, as well as its operation can be explained with reference to this illustration, before in the rest of the description of the structure, the function and the individual components of

Door closer will be described in detail with reference to the Figures 2-18 ,

In Fig. 1 It can be seen that a pillar bracket 4 of the door hinge 3 is attached to the D-pillar 1 and a door bracket 5 of the door hinge 3 on the door leaf 2. Both consoles 4, 5 are rotatably connected to one another by the hinge pin 6. The door hinge 3 allows the door 2 from the in Fig. 1 illustrated closed position on the D-pillar 1 by pivoting about the axis of rotation A in the direction of arrow 21 to open, if possible with an opening angle up to 180 or 270 °. The door 2 can, as in Fig. 1 represented at the rear of the motor vehicle, namely located on one of the D-pillars. It may be a symmetrically or asymmetrically split rear door or even an undivided door. The door lock according to the invention is to be used for each of these cases.

The door lock is located, as Fig. 1 clarified, in the area of a recess 7 of the D-pillar 1. There is a locking block 8 of the door arrester with its base plate 9 on a receiving plate 10, for example, by means of screws firmly mounted. A fishing hook 11 extends, as the drawing shows, with a hook blade 13 through the base plate 9 through and is fixed to this, namely welded to this, as will be explained. With 12 the actual hook part of the fishing hook 11 and 13 is referred to its already mentioned hook sword.

With the locking block 8 a headband 18 cooperates, located in the in Fig. 1 illustrated closed position of the door leaf 2 freely extends through the base plate 9. At the free end of the headband 18 carries a Rastierungsrolle 19 as a contact element in a rotatable arrangement. In Fig. 1 are plastic body 46, as in Fig. 7 can be seen at the corners of the retaining clip 18, omitted for reasons of clarity. At the other end of the headband 18 by means of journals 17, as will be explained in detail later, mounted in bearing openings 16 of a bearing part 15 pivotally. The bearing part 15 is fastened to the door leaf 2 by means of a screw 20.

When the door 2 is opened, the bearing part 15 and thus also the headband 18 is taken, the Rastierungsrolle 19 while on a, as shown, arcuate Hook spring 14 rolls as career approximately in the direction of arrow 21a. If the door 2, the in Fig. 1 dashed lines (headband 18 ') shown 90 ° -Offnungsposition reached snaps the Rastierungsrolle 19' shown in dashed lines in a yet to be explained spring clip 39 in the hook portion 12 at the end of the hook spring 14, so that the door 2 is securely held in this position. The bearing journal 17 is shown purely schematically as 21 b of the pitch circle of the web until it reaches the position as a bearing journal 17 'in the 90 ° opening position of the door leaf 2. It can be seen the detent position of the retaining clip 18 'with the Rastierungsrolle 19' in the aforementioned spring clip 39 of the hook portion 12th

Details of in Fig. 1 shown bearing part 15 arise from Fig. 2, 3rd and 6 - 9 , The housing-like bearing part 15 has a particular for fixing to the door 2 rear wall 35 from which opposing side walls 25 are bent (sheet metal part). At the bottom are each outside stops 26 for limiting the pivotal movement of the retaining clip 18 (see. Fig. 8 ).

The headband 18 consists of two arms 27, 28, preferably made of round steel, starting from a hanger back 29. At the free ends, the arms 27, 28 angled to form the bearing pin 17 to the outside. The bridge back 29 has a plastic extrusion 30 as a sliding aid.

Thus, the headband 18 is pressed upon rotational movement of the door leaf 2 on the hook spring 14, preferably a leg spring 33 'is preferably arranged on the inside of the bearing part 15 arranged portions of the bearing pin 17. This is supported in each case with one end 33 on a projection 34 on the side parts 25 of the bearing part 15 and with the other leg 32 in the manner shown on the respective arms 27 and 28 from. Internal single springs take up little space and have a protected position in the housing-shaped bearing part 15.

The base plate 9 has for attachment to the receiving plate 10 ( Fig. 1 ) of the D-pillar 1 screw holes 23, 24 and in the upper portion of an approximately rectangular window 22 through which the headband 18, as in Fig. 2 represented, freely extending therethrough. In particular from Fig. 3 . 4 and 5 shows that the base plate 9 is a solid, easy to produce and also without much effort with the fishing hook 11 to be connected component. The same applies to the fishing hook 11, as well as out 10, 11 and 12 evident. Particularly noteworthy is that the one-piece fishing hooks 11 in a simple manner allows a high-strength connection to the base plate 9, so that the fishing hook 11 and in particular its hook portion 12 itself is highly resilient, both to high stresses in an individual case by quickly opening the door leaf. 2 with sudden engagement of the web 29 with the Rastierungsrolle 19 and the Kunststoffumspritzung 30 in the hook portion 12 as well as on the lifetime total.

The locking block 8 is mounted as follows: The base plate 9 has approximately centrally at the bottom of the window 22 a slot 36 whose width corresponds approximately to the sheet thickness of the fishing hook 11. The fishing hook 11 is on its underside, namely on its hook sword 13, with a paragraph 37 ( Fig. 10 ) Mistake. The fishing hook 11 is inserted with the hook blade 13 in the window 22 of the base plate 9 in the slot 36 such that the step 37 rests against the back of the base plate 9 ( Fig. 4 ), while a projection 38 extends from the front of the base plate 9 to the front ( Fig. 5 ). In this position, the hook blade 13 is welded to the back of the base plate 9 from top to bottom on both sides. It is also possible to additionally weld the projection 38 on the front side of the base plate 9 to the base plate 9 as well. In any case, a high-strength connection is created.

Now the hook spring 14 is mounted from spring steel, which has a long continuous, namely one-piece guide track for the encapsulation 30 (FIG. Fig. 2, 3rd . 6 ) and in particular for the Rastierungsrolle 19 ( Fig. 1 . 7 . 14 17) into the spring clip 39 forms, which closes the hook-side end of the hook spring 14. When inserting the hook spring 14 in the fishing hook 11, it is positioned so that a square projection 40 which is located in the vertical plane of the base plate 9 on the top of the fishing hook 11 ( Fig. 10 ), with a correspondingly square and appropriately sized opening 41 in the hook spring 14 is engaged (see. Fig. 4, 5 and 11 ). With the upper end of the projection 40, the hook spring 14 is now riveted so that the track of the hook spring 14 is smooth and level.

The long hook spring 14 has a rounded edge of material to the spring properties to improve and at the same time to avoid wear on the encapsulation 30.

The formation of the spring clip 39, in particular as a continuation of the uninterrupted track of the hook spring 14, has an important function. Between the upper arch 42 of the spring clip 39 and the adjacent hook portion 12 is a gap (see. Fig. 5 or 13 ), so that the upper part 42 spring back and thus the spring clip 39 can open when the bridge back 29 meets with the encapsulation 30 on the spring clip 39, then take his detent position within the spring clip 39.

In one embodiment of the door arrester according to the invention, without significant changes to be made to the structure described above, instead of the encapsulation 30 already out Fig. 1 apparent Rastierungsrolle 19 used in Fig. 7-17 can be seen in different views and functional positions. It preferably consists of a longitudinally slotted slide bushing 43 made of plastic ( Fig. 14 ), which expediently carries on its outside a thin metal slit also slotted. The Gleitführungsbuchse 43 is placed on the bridge back 29, so that they are the z. In Fig. 14 shown position occupies. There it is provided after insertion into an injection mold with a wear-resistant plastic encapsulation 44, so that a rotatably mounted on the bridge back 29 Rastierungsrolle 19 is formed. At the same time 18 molded plastic sliders, hereinafter referred to as plastic body 46, injected onto the arcuate portions 45 of the retaining clip 18, whose underside is substantially equal to the underside of the encapsulation 44 ( Fig. 16, 17 ).

With the replacement of the molded on the bridge back 29 extrusion coating 30 ( Fig. 2 and 6 ) By the above-described and shown in the drawings rotatably mounted on the bridge back 29 Rastierungsrolle 19, the wear of this component, which results along the guideway on the hook spring 14, very substantially reduced, so that a correspondingly long life for this by friction claimed component of the door arrester invention.

A further reduction of the friction-related wear results from a further special feature in the design of the hook spring 14, namely in the formation of the Spring clip 39. Their opening must be spread by the Rastierungsrolle 19 at each inlet into the detent position within the spring clip 39, with the result of a corresponding friction between the plastic extrusion coating 30 and 44 and the spring clip 39. To avoid this friction is namely a sliding plate 47 (in particular Fig. 10-17 ) are fastened to the catch hook 11 with two opposite slide tracks 48 in the manner shown in the drawings. This is preferably done by simply interposing the slide plate 47 between the hook spring 14 and the underlying fishing hooks 11 in the region of the spring clip 39. The shape and position of the slide plate 47 is best off Fig. 10 to recognize. In this position on the fishing hook 11, the sliding plate 47 is securely positioned and is secured with the riveting of the hook spring 14 by the projection 40 on the fishing hook 11.

The two slideways 48 are slightly, in the present embodiment by 0.5 mm, higher on the fishing hook 11 as the intermediate middle part 50 therebetween. This means that the Rastierungsrolle 19 upon reaching the spring clip 39 (FIG. Fig. 16 ) down no contact with the hook spring 14 has. For now, the plastic body 46 comes into engagement with the slideways 48 and so support the headband 18 when entering the Rastierungsrolle 19 in the spring clip 39. Once the Rastierungsrolle 19, as in Fig. 16 shown, impinges on the upwardly curved portion 51 of the spring clip 39, it now rolls on the upper inside of the spring clip 39 in a clockwise rotation - from until reaching the in Fig. 17 shown latching position. In FIGS. 16 and 17 is omitted for reasons of clarity of the hook portion 12 in the illustration. It goes without saying that the return path of the Rastierungsrolle 19 runs just as gently and with very little wear, both what the running out of the spring clip 39 and the leadership and contact on the track of the hook spring 14 under the pressure of the torsion springs 31st As for.

In Fig. 7 . 8, 9 and in particular in Fig. 15 For example, another preferred embodiment of the retaining clip 18 is illustrated in connection with a single leg spring 31a. The arm 27 has in the region of its free end on a step-shaped angled portion 50 having an inwardly angled bearing pin 17a at the end, which is aligned with the bearing pin 17 of the other arm 28, which is not changed from the previously described form, and a common pivot axis for the headband 18 on the Bearing part 15 forms. For mounting the headband 18 is attached to the bearing part 15, that the bearing pins 17, 17 a their associated bearing openings 16 (in Fig. 15 concealed), so that the headband 18 can be brought into the assigned position on the bearing part 15 by simple lateral displacement, in which the bearing pins 17, 17a get into the bearing openings 16. With a locking ring 51a of the bearing pin 17a is rotatably fixed to the bearing part 15, so that thus the headband 18 is secured in the associated position. For pressing the bearing bracket 18 to the hook spring 14 is a single leg spring 31 a of the type shown on the bearing pin 17, the free leg ends 33 a and 32 a attack on the bearing part 15 and on the arm 28 of the retaining clip 18 and secured there. The aforementioned type of mounting of the retaining clip 18 in the unsymmetrical shape described is much simpler than the assembly of the symmetrical retaining bracket 18 z. B. according to Fig. 6 , Because this bracket 18 must, so that its bearing pin 17 can engage in the bearing openings 16 of the bearing part 15, 27 resiliently compressed in the region of the free ends of the arms 27, then placed in the bearing part 15 in position and after releasing the pressure force in the final position to be brought.

In Fig. 18 is a modification of components of the embodiment according to Fig. 7-17 shown. Notwithstanding the structure eg according to Fig. 11 the sliding plate 47 is disposed over the hook spring 14 and secured to the catch hook 11 to reliably press down the end of the hook spring 14 in the region of the spring clip 39. The projection 40 on the hook blade 13 of the fishing hook 11 is at a distance in front of the base plate 9. The shrinkage of the Rastierungsrolle 19 (not shown here, but for example FIGS. 16 and 17 apparent) in the spring clip 39 runs in the rest, as already described above, from. When the plastic bodies 46 ( Fig. 14 Get into engagement with the sliding plate 47, they lift the Rastierungsrolle 19, so that it rolls when hitting the upwardly curved portion 51 of the spring clip 39 on the upper inside of the spring clip 39 - clockwise turning - until reaching the in Fig. 17 shown latching position. To lift the Rastierungsrolle 19 are either when the sliding plate 47 smooth and flat on the surface - in contrast to the upwardly projecting lateral slideways 48 (see. Fig. 10 ) -, the plastic body 46 against the Rastierungsrolle 19 downward, so that the Rastierungsrolle 19, the sliding plate 47 is not affected. Or the sliding plate 47 has as in Fig. 10 lateral slideways 48, which also raise the Rastierungsrolle 19 effect, if as in Fig. 16 the plastic body 46 engage with the slideways 48. The fact that the sliding plate 47 presses the hook spring 14 down, it is reliably avoided that the Rastierungsrolle 19, the hook spring 14 can touch when it enters the spring clamp 39. Otherwise, the in Fig. 18 not shown further components of the door arrester the components of the embodiment according to Fig. 7-17 correspond.

It goes without saying that the features of the various embodiments shown and described are interchangeable without departing from the invention defined in the claims. So you can, for example, instead of the Rastierungsrolle 19 on the bridge back 29 of the retaining clip 18 in the embodiment according to Fig. 15 use a mere plastic encapsulation as a contact element, as in the embodiment in Fig. 2 represented and designated 30. Instead of a single component for the fishing hook 11 starting from the hook part 12 to the projection 38 can also be a multi-part fishing hook 11 connect to the base plate 9, which in turn can also be made in several parts, even if the illustrated and described form preferred because of their advantages becomes.
