Abstract

It is important to reliably position a tower (20), which has a lock cylinder or a styling dummy, in its inserted position in a carrier and secure it with a securing screw (50). For this purpose, it is proposed to mount in the carrier (10) a control lever (30) pivotally having a locking arm (31). The tower (20) in turn has a lateral locking opening (21) for the locking arm (31). If, after inserting the tower (20), the control lever (30) is brought into a blocking position (30.1), its blocking arm (31) engages in the blocking opening (21) of the tower (20) and prevents the tower from being pulled out (14) (20). Bringing the control lever (30) in a position where the locking arm (31) is located outside the locking opening (21), then there is a release position, where the tower (20) can be removed or installed. The locking position of the control lever (30) is additionally secured by the locking screw (50).

Description

The invention is directed to a handle specified in the preamble of claim 1. Art. To secure the insertion position of the tower in the carrier, there are various known measures in which a screw is involved.

In a handle of the type mentioned in the preamble (DE 30 30 519 A1), the tower is mounted by a Einrenkbewegung in the carrier. In this Einrenkbewegung the tower is first inserted into the carrier and then, parallel to the outside of the door, moved against the already previously mounted in the carrier handle. The end position of the tower in this shift is locked by a locking screw, which can be screwed laterally in the carrier.

Another known measure for securing the tower consists in the use of a sliding parallel to the door plane in the carrier slide, which is displaced by a rotatably mounted in the carrier actuating screw (DE 199 50 172 A1, DE 101 46 026 C1). The carrier has blocking means which retract into the tower's anti-locking means and secure it in the inserted position in the carrier.

The invention has for its object to develop a reliable device for handling mentioned in the preamble of claim 1 species, which secures the tower in its inserted position in the carrier in a new way. This is inventively achieved by the measures listed in claim 1, which have the following special significance.

The invention proposes to pivotally support at least one control lever in the carrier, which has a blocking arm. This locking arm is associated with a locking opening on a side surface of the tower. Normally, the control lever is in a release position where its barrier arm is positioned outside the tower-side barrier opening. Then the tower can easily be plugged in and pulled out again. However, the control lever can also be transferred to a locked position, where its locking arm engages in the tower-side locking opening. Then the insertion position of the tower is held in the carrier. By securing screws the locking lever is secured at least in its locked position. At least the reversal of the control lever between the release position and the blocking position can be effected in an advantageous manner by the tower located on the control surfaces, as proposed in claim 2. This relieves the fitter, who only needs to insert the tower into the carrier from the outside of the door. The reversal of the control lever in its lock-holding the locked position then takes place automatically.

Of the handle according to the invention, only a carrier 10, a door outer panel 11 and a tower 20 are shown in the drawings. The carrier 10 is mounted in the door interior of the inside of the door and comes to rest on the back 12 of the door outer panel 11. The tower 20 has in the present case a lock cylinder of the only one working end 15 can be seen, which cooperates with a lock not shown in detail inside the door. A pulse spring, the turns 16 in the cross-sectional view of FIG. 2 can be seen, provides for a defined zero position of the working end 15. The lock cylinder is, as is apparent from Fig. 3, inserted from the outside of the door in the direction of the arrow 24. For this purpose, the carrier 10 has a passage 17 and the door outer panel 11 a cutout 18. The end position of the insertion movement is shown in Fig. 6. As can be seen, then comes the tower 20 with its tower end 23 on the front side 13 of the door outer panel 11 to lie. The lock cylinder located inside the tower is then accessible from the outside of the door 13 for a key.

The peculiarity of the invention can best be seen from the cross-sectional view of FIG. 2 and in perspective views of FIGS. 7 and 8. The invention has two control levers 30, 30 ', which are pivotally mounted on opposite sides of the tower 20, which by the position of the pivot axes 34, 34' in Fig. 2nd is clear. The two control levers 30, 30 'have an analogous structure, but are arranged in opposite directions to each other in the carrier and act together in unison with the tower 20 together. Because of their analogy, it is sufficient to describe only the structure of a control lever 30 with reference to FIGS. 7 and 8, because it also determines the structure of the mirror-image control lever 30 '.

The control lever 30 includes three arms 31 to 33. These include first a locking arm 31 and a stop arm 32, the two each consist of transverse strips 35, 36. The longitudinal course of the strips 35, 36 extends parallel to the in Fig. 2 indicated by dash-dotted lines 19 level of the carrier 10. The two arms 31, 32 are thus formed by the cross section of the two strips 35, 36 and extend substantially parallel to the dash-dotted lines in Fig. 3 illustrated tower axis 25. The third arm 33 will be referred to for even more apparent reasons "reinforcing arm". The reinforcing arm 33 extends in the position of the control lever 30 shown in FIG. 6 at 30.1 substantially parallel to the aforementioned support plane 19 and thus perpendicular to the tower axis 25. The position 30.1 is then a "locked position" of the control lever 30 for the following reason.

The tower 20 has a rectangular cross-section with recognizable from Fig. 6, substantially flat side surfaces 26, 49, 26 '. On opposite side surfaces 26, 26 'is, as is apparent from Fig. 2, the tower 20 with locking openings 21, 21' is provided. These consist of a continuous transverse channel 27, 27 ', the insertion of the movement 24 opposing inner channel side walls 28, 28' play a special role. In the final insertion position according to FIG. 2, namely, the two locking arms 31, 31 'engage in the locking openings 21, 21'. The tower 20 has in the transition region to its outer tower end 23 has a shoulder, in which there are two axial grooves 22, 22 ', which are open and linear in the insertion direction. 2, the stop arms 32, 32 'travel into the axial grooves 22, 22'.

If unauthorized persons attempt to remove the built-in tower 20 from its installation position in the direction of the force arrow 14, a pressure is exerted on the free ends of the blocking arms 31, 31 'by the mentioned channel side walls 28, 28'. exercised. It arises with respect to the pivot axes 34, 34 ', a torque 37, 37', which, with suitable profiling of the locking arm end and the pressure-effective channel side wall 28, 28 'drives the arms even deeper into the locking openings 21, 21' from the tower 20. These torques 37, 37 'are received by the outer inner walls 29 and 29' of the axial grooves 22, 22 'because the upper end portions of the respective stop arms 32, 32' are supported thereon.

As best seen in FIG. 6, the pivot bearings 40, 40 'of the two control levers 30, 30' are arranged on the rear side 38 of the carrier 10. The bearing parts 41 of the control lever 30, 30 'consist of two bearing journals, which, as FIG. 7 illustrates, extend the two strips 35, 36 in the longitudinal direction. The abutment parts 42, 42 'consist of bearing receptacles 42, 42', which can be open in the insertion direction 24 of the tower 20. In this area, but spring means are also provided, which consist of a formed on the carrier 10 spring nose 39 and 39 ', as can be seen from Fig. 4. These spring lugs extend in extension of a section of the carrier-side counter bearing 42, 42 '. The spring lugs 39, 39 'endeavor to exert otherwise already, in connection with FIG. 2 explained torque 37 or 37' on the two levers 30, 30 '. The spring lugs 39, 39 'endeavor to transfer the blocking arms 31, 31' into the blocking position 30.1 or 30.1 ', which has already been mentioned several times, ie to move in the direction of folding of the blocking arms 31, 31' towards the tower 20.

In the insertion movement 24 of the tower, various control surfaces 43, 43 ', which can be seen from FIGS. 3 and 4, abut against the inclined inner flanks of the locking arms 31, 31' and transfer them into a second pivot position, designated 30.2 and 30.2 'in FIG. 4 , In the sense of such control surfaces then act, in the train of further axial movement, the tower side surfaces 26 and 26 '. This changes only at the transition between the insertion phase of Fig. 5 in Fig. 6, when the two-sided locking arms 31, 31 'are aligned with the locking opening 21, 21' in the tower 20. Then snap the locking arms 31, 31 'and provide the above-described securing the insertion position of the tower 20 in the carrier 10th

To be able to dismantle the tower 20 again, the locking arms 31, 31 'must be transferred again into the last-mentioned pivoting position 30.2, 30.2' until the Locking openings 21, 21 'in the tower 20 are released. This pivotal position 30.2, 30.2 'thus proves to be a "release position" of the two-sided control lever 30, 30'. In the release position 30.2, 30.2 ', the reinforcement arms 30, 30' occupy an inclination position illustrated by the auxiliary lines 44, 44 'in FIG. 4. This inclination position 44, 44 'can be achieved by moving the reinforcing arms 33, 33', so that they can be used as handles for releasing the tower 20.

In the blocking position 30.1, 30.1 'of the two control levers 30, 30' according to FIG. 6 are, as can be seen from Fig. 7, the locking arms 33, 33 'side by side. They are based, according to FIG. 6, on the back of the carrier 38. The pull-out forces 14 acting on the tower 20 mean that not only the bearing pins 41, 41 'increasingly press against the carrier 10, but also the reinforcing arms 33, 33'. As a result, the handle according to the invention can withstand much higher pull-out forces 14; the departure of the vehicle door is prevented. On the other hand, instead of metallic materials for producing the self-contained locking arms 31, 31 'on the one hand and the support 10 with its counter bearing points 42, it is also possible to use inexpensive plastics. The support position 45, 45 'of the reinforcing arms 33, 33' on both sides is illustrated in FIGS. 6, 7 by the auxiliary lines 45, 45 '.

In this support position 45, 45 'are also the two ends of the reinforcing arms 33, 33' engaged with each other, as a comparison between Fig. 7 and 8 shows. For this purpose, the dome surfaces 46, 46 'and counterdoscoupling surfaces 47, 47' shown in FIG. 8 are used. The dome surfaces consist of apertures 46, 46 'at the free ends of the two-sided arms 33, 33', while the Gegenkuppelflächen are simply formed from extension pieces 47, 47 'of the respective bearing pins 41, 41'. In the blocking position 30.1, 30.1 'is an engagement between 47, 46' and 47 ', 46 before. The two arms 33, 33 'are connected in pairs at both ends. By this mutual engagement of adjacent pairs of arms 33, 33 ', the carrier 10 can withstand much higher extraction forces 14. It is advantageous to provide two such reinforcing arms 33, 33 'at both ends of the strips 35, 36 shown in FIG. This gives in the blocking position 30.1, 30.1 'a frame-shaped structure, to which four reinforcing arms and the Both strips 31, 32 are involved. The tower 20 is then enclosed on all sides. This results in a very high pull-out strength.

In the blocking position 30.1, 30.1 ', the two levers 30, 30' are secured by a locking screw 50 shown in FIG. 6, the screw shank 52 of which can be screwed into a shoulder 48 of the carrier 10. The screw head 51 can either directly or by means of washers od. Like. The locking arms 31 and 31 'engage behind and lock them in their described support position 45, 45' on the carrier 10.
