Abstract

An automotive door or hatch has a hand operated lever and locking mechanism. The lock has a screw whose action is reinforced by a one-piece pivoting L-shaped bar within the surrounding frame. One end of the bar (25) forms part of the lock mechanism and pivots between locked presentation and an open presentation.

Description

The invention is directed to a handle fitting specified in the preamble of claim 1 Art.

In the known handle fitting of this type ( DE 30 30 519 C2 ), the carrier is fastened to the door from the inside of the door with two screws. The corresponding handle, however, is passed from the outside of the door through suitable openings in the door outer panel and in the carrier and hooked by a Einrenkbewegung with his one end of the handle in a bearing on the back of the carrier. The other end of the handle is then aligned with an actuating linkage from the lock. To secure this mounting position of the handle, a lock cylinder tower is used, which may be formed without lock cylinder and then acts as a tower dummy. These elements are to be called "tower" shortly afterwards. This tower is mounted from the outside of the door by a Einrenkbewegung positive fit in the carrier. This Einrenkbewegung comprises in the case of assembly initially takes place substantially perpendicular to the carrier insertion phase of the tower through an opening in the carrier, which is then a shift phase in the direction of the wearer followed. Here shoulders on the tower drive behind counter shoulders on the carrier. To secure the mounting position of the tower serves as a holding means transverse to the tower screw, which is screwed in a threaded receptacle of the carrier. The screw is accessible laterally through an opening in the rebate area of the door and runs with its threaded axis in the direction of the phase of displacement of the tower during assembly. If the screw is tightened, its inner end of the screw is supported on a side face of the tower and thus prevents a reverse displacement of the tower in the support which is opposite the displacement phase of the pivoting movement and thus precludes unintentional disassembly of the tower from the support.

In another handle fitting of this type ( DE 196 33 894 A1 ), the tower is also mounted by a Einrenkbewegung positive fit in the carrier. Also there serves as a holding means for securing the mounting position of the tower a screw. But this screw is accessible from the inside of the door. The screw passes through an attachment point in the carrier and can be screwed into a threaded receptacle in the checkered area of the tower, which, as described above, comes to lie next to the handle after assembly on the outside of the door. The screw has here the double function on the one hand to ensure the completed positive mounting of the tower and on the other hand to serve for fastening the outer lining of the door to the carrier.

In the case of a handle fitting which is not manually mounted in a form-fitting manner in the carrier but is inserted into the carrier only perpendicular to the door plane ( DE 101 46 026 C1 ) is used in the carrier transversely to the tower guided slide for a subsequent positive connection between the slide and tower. The movement of the slider is also done here by a transverse to the tower in the carrier rotatably mounted screw, which engages with its threaded end in a threaded receptacle in the carrier. In order to achieve a positive fit, here the slider is used by the screw against the tower back, with shoulders at the inner end of the slide drive behind counter-shoulders on the back of the tower. After the carriage has traced behind the tower form-fitting and thus only indirectly, namely on the guides in the carrier, the tower holds in the carrier, also engages the slider serving for movement screw with its inner end in a lateral recess of the tower.

The strength of the mounting position of the tower depends on handle fittings with slide on the strength of the slider in the carrier. This handle fitting is expensive and space-consuming, because for mounting a slide, a carriage guide on the carrier, a screw for actuating the slide and a bearing of the screw in the carrier are required.

There is another handle fitting ( DE 199 50 172 A1 ) according to the preamble of claim 1, wherein the tower is manually inserted only in a corresponding opening of the carrier, without first a positive connection comes about. On guide rails in the carrier a slider is arranged transversely to the tower slidably. To displace the carriage, an engaging in a threaded receptacle of the slider screw, which is supported with its screw head on a side surface of the carrier. A threaded shaft enclosing the compression spring supports the retraction movement of the slider when turning the screw. By pressing the screw, the slider moves the inserted tower transversely to the previous insertion direction, until a positive connection between slide and carrier on the one hand and tower and slide on the other hand is achieved. The screw runs here in the direction of the rails in the carrier and is accessible through a side opening in the door rabbet. In In this case, the positive connection between the tower and the carrier only comes about through the slide.

The invention has for its object to develop a low-cost handle fitting that improves the risk of theft of equipped with this fitting vehicles and the ease of use of the tower. Installation and removal guaranteed. This is inventively achieved by the measures listed in claim 1, which have the following special significance.

In the handle fitting according to claim 1, in addition to the holding means, which ensures the positive connection of the tower on the carrier, still an integrally formed latch on the carrier, which has a bolt end and an actuating end. Upon actuation of the actuation end of the latch, the latch end is conformally moved and displaces between a latch position and an unlock position. In this case, the tower has a receptacle for the bolt end, in which the bolt end enters in the locking position. In addition, the latch is spring-loaded at least in the direction of the locking position of its locking end.

In the invention, the latch is a rotary latch whose axis of rotation is seated on the carrier and the operating end of the rotary latch covers at least partially in the locking or unlocking the holding means.

The operating end of the bolt is accessible at least in the unlocked position from the inside of the door. Thus, the bolt provided on the carrier from the outside for unauthorized persons neither in the region of its bolt end nor its operating end can be manipulated. Only authorized persons who have access to the inside of the door can act on the bolt during assembly or disassembly of the tower and transfer it to its unlocking position against the spring load. This takes place during the production of the vehicle or subsequently during the repair. Only then is the holding means detachable or securable and the tower by a manual Einrenkbewegung from its positive connection in the carrier or expandable. Thus, both the theft security given, as well as a comfortable handling of the tower during installation and removal guaranteed.

It is particularly advantageous to use a tilt spring for spring loading of the bolt. The tilt spring engages at one end on the carrier and the other on the bolt and determines on both sides of a central dead center two stable end positions of the bolt. In one end position, the locking end is in the locking position and in the other end position is the unlocking position of the locking end. For assembly and disassembly, except the setting or loosening of the holding means between tower and carrier only the operating end of the bolt manually moved to the dead center, whereupon the bolt end automatically snaps into the stable locking position or unlocking position, which then each by the spring action of the tilt spring are secured.

One should set the access point for the operating end of the bolt to that place, where also the actuating point for the holding means of the carrier located, for example, the head of a fastening screw. This point must in any case be accessible from the inside of the door. All other areas of the carrier and the door can be easily occupied by other components. This allows a particularly intensive utilization of the door inner surface.

Further measures and advantages of the invention will become apparent from the dependent claims, the following description and the drawings. In the drawings, the invention is illustrated in two embodiments; show it:

The in Fig. 1 and 2 handle fitting shown comprises a carrier 10, which on the in the Fig. 1 visible inside a door or flap in two places 13, 14 can be attached. In dashed lines is in the Fig. 1 only a portion 12 of the outer lining of the door indicated. In breakthroughs 15, 16 and 17 of the carrier 10 further components of the handle fitting are visible.

To these other components of the handle fitting belongs above all a handle 20 having two angled ends 21, 22. The handle 20 is of the in the Fig. 1 invisible outside of the door 12 from manually mounted through two openings in the door outer panel, which are at least partially aligned with the openings 15 and 17 of the support 10. The one end of the handle 21 is mounted in bearings 18 of the carrier 10, which is done by a Einrenkbewegung. In this Einrenkbewegung also takes the other end of the handle 22 part, which has a hook head 24 at its inner front end, which in use on the back of the carrier with a located in the door, not closer together shown lock linkage, such as a lock lever. This grip end 22 with the hook head 24 moves through the mentioned third opening 17 in the carrier 10 a.

The opening 17 is provided in the present case with a narrow and wide range. In the wide area of the opening 17, the already mentioned above tower 30 is mounted, also from the outside of the door. This can also be done by a manual Einrenkbewegung. For this purpose, the tower 30 has two shoulders 31, 32, which drive in the Einrenkmontage behind wall portions of the carrier 10, which are arranged in the transition between the narrow and wide region of the third opening 17. Opposite them, the tower 30 still has a tab 35, which is part of the above-mentioned second attachment point 14. As a holding means at both attachment points 13, 14 are used in the present case screws whose handle to be handled 33, 34 are accessible only from the inside of the door 11 from. The attachment point 14 thus comprises, besides the actual screw with its screw head 34, also a threaded receptacle in the tower 30. There is a three-point attachment of the tower 30 on the carrier 10 before. Finally, the screw at the fastening point 14 also serves for fastening the outer lining of the door 12 to the carrier 10.

How out Fig. 1 can be seen further, the carrier 10 has a latch 25 which is formed as a one-piece rotary latch. For this purpose, the carrier 10 has an axis of rotation 19, which in the present case substantially runs perpendicular to the door plane and on which the bolt 25 is rotatably mounted. The bolt 25 has an active actuating end to be actuated 27 and a passive, the actuation following bolt end 26. The bolt 25 is force-loaded by a spring 28 whose endeavored by the arrow 29 spring load strives the bolt 25 in its by the auxiliary line 25.1 in Fig. 1 clarified illustrated locking position. This locking position 25.1 results because the latch end 26 moves into a receptacle 36 of the tower 30. The receptacle 36 may include the latch end 26 on all sides, such as a bag, which is why not only the expansion of the tower, but also his further impressions are prevented inside the door.

In the locking position 25.1 is its operating end 27 substantially in alignment with the screw head 34. For installation and removal of the tower 30, its operating end 27 is moved from the inside of the door until the latch 25 by the auxiliary line 25.2 in Fig. 2 clarified unlocking position has reached. Then the latch end 26 is located outside of the receptacle 36 from the tower 30 and the operating end 27 is removed from the screw head 34, so the installation and removal of the tower 30 in the carrier 10 are possible; the screw head 34 of the attachment 14 is easily accessible. When the screw is released, the tower 30 can then be removed from the third breakthrough 17 by a sequence of movements in the opposite direction to that during the mounting movement.

In the unlocking position 25.2, of course, the spring 28 is more taut than in the locking position 25.1 and generates a greater restoring force 29. This does not bother, however, because when screwing and unscrewing the screw head 34 at this point a turning tool is anyway, which is the bolt Operation end 27 can hold back.

Of particular importance is that the actuating end 27 of the latch 25 is located at the same location where the one attachment point 14 of the carrier 10 is present. The screw at the attachment point 14 is the rest, as described, at the same time the retaining means for securing the tower 30 on the support 10. This point 27 is therefore accessible to a tool from the inside of the door in any case, while all other areas on the inside of the door from others Components of the door, such as insulation means, can be covered. This includes, for example, the already mentioned, not shown in detail lock for securing and unlocking an integrated into the tower 30 lock cylinder 37 is used. The lock cylinder 37 has a cylinder outlet 38, which acts on the securing and Entsicherungsmittel in the lock when the lock cylinder 37 is rotated by a key.

In the 3 and 4 a further embodiment of a handle fitting according to the invention is shown. For the naming of analog components, the same reference numerals are used as in the previous embodiment, which is why the previous description applies to that extent. All you have to do is address the differences.

The main difference is that instead of the compression spring used in the preceding embodiment, a tilt spring 40 is used, the two spring legs are hinged at one end fixed at 41 on the carrier 10 and the other movable on the latch 25. In the figures, a so-called "dead center" is shown in phantom, which connects the fixed connection point 41 with the axis of rotation 19 of the rotary latch 25. In Fig. 3 the tilt spring 40 is in its first end position, where the movable connection point of the tilt spring 40 in Fig. 3 located above the dead center 43 at 42.1. In the present case, this second connection point acts on the actuating end 27 of the bolt 25. In this first end position 42.1 the tilt spring exerts a by the arrow 44.1 in Fig. 3 illustrated torque on the latch 25 from. As a result, its bolt end 26 in the clockwise direction according to the rotation arrow 45.1 of Fig. 3 emotional. It then lies, as the auxiliary line 25.1 in Fig. 3 illustrates a locking position of the rotary latch 25 before. Then, similar to the first embodiment, the second attachment point 14 is free to tighten or loosen the screw 34 can. Also in this case, the screw 34 serves as a holding means for securing the tower 30 on the carrier and on in Fig. 3 not shown in detail outside door trim.

If you want to remove the tower, so first the fixing screw 34 must be solved, with its threaded end in a threaded receptacle that Area is screwed by the tower 30, which is located on the outside of the door paneling. But that is not enough. Then the latch 25 is lifted out of its locking position 25.1 in the tower 30. This is done by manipulating a rib provided on the operating end 27 of the bolt; the rib or handle is moved counterclockwise. During this movement, the second connection point of the tipping spring 40 crosses the dead center line 43. Until the dead center line, the tipping spring 40 is tensioned under pressure. But then, when the dead center line 43 is exceeded, the spring 40 automatically snaps into its second, in Fig. 4 42.2 designated second stable end position, which is marked 42.2. The second junction 42.2 is then below the also in Fig. 4 dash-dotted lines, already mentioned dead center line 43. In this second end position 42.2, the tilt spring 40 exerts a torque in the counterclockwise direction on the actuating end 27, which in Fig. 4 is illustrated with 44.2. Then also the bolt end 26 is in the counterclockwise direction in the sense of the rotary arrow 45.2 out of the pocket of the tower 30. There is already described in the first embodiment unlocking 25.2 of the rotary latch 25 before. Now can be disassembled by a retrograde Einrenkbewegung the tower 30 from the carrier.

In the present case, the area of the carrier 10, which receives the tower 30 and at the same time serves for pivotal mounting of the bolt 25, a self-made insert 39, which is firmly connected before use of the carrier with this structural unit. This has the advantage of a unitary support base in which different inserts 39 can be inserted as needed to create supports for different types of construction or towers 30.
