A door leaf 60 provided with a bevel 61 Cabinet or housing is against a frame profile 62 closed cabinet or housing can be created, in which Frame profile a locking mechanism 63 is arranged, such as these in detail in the generic EP 0 675 994 B1 with the locking rod 12 and interacting parts is described.

To actuate the locking mechanism 63 is on the outside the door leaf 60 a door plate 10 attached .which a first door plate area 11 with the one arranged therein Handle 13 and a second door panel area 12, in which one to be described in detail Locking device for the handle 13 is arranged. During the first door plate area 11 with handle 13 at closed door comes to rest in front of the frame profile 62, is the second door plate area 12 outside the Frame profile 62 of the cabinet or housing, so that over the door leaf 60 functionally necessary in the Cabinet or housing protruding parts with Cover caps 16 are provided, the door leaf in assigned Pass through recesses 64. As Fig. 1 continues to can be seen is at the upper end of the door plate 10 inserted blind cap 14 provided for receiving for example, a manufacturer emblem can serve at the bottom of the door plate 10 to cover the there intended opening for a here in this case used locking device for the handle 13 a Sliding cap 15 is arranged which when handling the Locking device can be moved to the left, so that the locking device arranged behind it for example in the form of a cylinder lock, which cylinder lock on the back by the assigned Cover cap 16 is covered.

The functional structure of the closure device or Door sign as the carrier of the actuation functions is the 2 and 3 in detail. Is to forward that with regard to any Installation of the door plate 10 for a left and Right-hinged door, which rotates 180 ° Door sign required, the door sign symmetrical is designed and equipped so that for a conversion of the Door plate only the one inserted in the door plate Handle is to be implemented accordingly, as is the case in detail is still described.

In the area of the two ends of the handle 13 jumps to the Door sign and here at its first door sign area on the inside in each case a hat-shaped bearing collar 17 in front which is each a pinion 18 is mounted. The basic body of the pinion 18 consists of a disc 19 which with a bearing projection 19a directed towards the handle 13 in engages the hat-shaped bearing ring 17 and stored here is (see Fig. 4 b). On the one facing the door leaf 60 One side is placed on the disc 19 Pinion gear 20, the diameter of the Pinion gear 20 is less than the diameter of the Disc 19. On the bearing side, pinion 18 additionally a U-shaped closed projection 21, the through the hat-shaped bearing ring 17 through to the receptacle of the handle 13 serving depression is sufficient that the handle 13 directly on the pinion 18th is to be determined. The axis of rotation for the handle 13 Forming joint mandrel 22 is positively in the assigned opening 18a of the pinion 18 and is inserted together with corresponding storage projections of the handle 13 by means of corresponding recordings in Joint mandrel 22 and handle 13 on the projection 21 of the Pinion 18 fixed so that on the one hand the handle 13 around the axis 23 pivotable perpendicular to the plane of the door plate , but on the other hand when the handle 13 is rotated parallel to the plane of the door plate 10, a rotary movement of the Pinion 18 takes place. As can be seen in FIG. 5, the Handle 13 under the effect of one in from the Door plate 10 extended position biasing spring 24th

To transmit the rotational movement of the pinion 18 in a A rack 25 is the longitudinal movement of the locking mechanism 63 provided that is designed as a two-leg angle. On the leg 26 arranged parallel to the door plate level is at the front edge 27 with the pinion 18th interacting gearing arranged while the Rack 25 with the angled guide leg 30 on the inside of the housing surface of the door plate 10 located guide tabs 31 is guided. On the thigh 26 connection openings 29 are formed, in which in a way, not shown, with the door closed the locking mechanism 63 engage trained approaches, so that the displacement of the rack 25 in the actuation the locking mechanism 63 is implemented. Because of the symmetrical design of the door plate two pinion 18 the bearing rings 17 are stored, the extends Rack 25 over both pinions 18, only one each Pinion under the action of the handle 13 as a drive pinion works while the other sprocket at the Displacement of the rack 25 rotates empty.

Since the leg 26 of the rack 25 on the opposite of the Pinion toothing 20 protruding disk 19, are both pinions by the rack 25 in their Storage held in the respective bearing rim 17; the Rack 25, for its part, points in the guide leg 30 an elongated slot 32 in which one a locking plate 33 to be described Nose 34 engages so that on the door plate 10th held locking plate 33, the rack 25 out and is fixed and therefore without additional Attachment measures the pinion 18 holds, the pinion 18 again hold the handle 13 as described.

The mentioned locking plate 33 is by means of it penetrating screws 38 on the inside of the door plate 10 held such that the locking plate 33 in the Vertical is slidable. In their middle range the locking plate 33 has a locking projection 41, which in a hook 66 formed on the handle 13 (Fig. 5) engages or releases it, so that depending on the Position of the locking plate 32 in the door plate 10, the handle 13 under the action of the spring 24 from the door plate 10 folded out or in their folded position is held.

The locking plate 33 extends from its attachment the screws 38 laterally to over the second Door plate area 12 and acts here trained on her projecting actuating surfaces 35 with the closing thumb of a lock cylinder, not shown, which, 1, in the lower opening 44 in Door plate 10 inserted and backwards by one Holding bracket 37 is held. As in the synopsis with 1, covers the lower cover cap 16 insofar as the locking cylinder, not shown Bracket 37 from. The actuating surfaces 35 are with a End stop 36 for the lock thumb, not shown Cylinder lock provided as a locking device. Between the two symmetrically arranged actuating surfaces 35 there is an enclosure 39 for an underlying one Spring 40, which on projections of the door plate 10 and on the inside of the housing 39 of the locking plate 33 supports that the spring action in both Actuating directions of the locking plate 33 affects.

As can be seen in particular from FIG. 3, the Openings 44 for insertion of the locking device Guide slot 45 in which each of the inserted sliding cover 15 is guided or the blind cap 14 can be inserted.

The door plate 10 is attached to the door leaf reaching through the door leaf and in screw domes 42 of the Door plate 10 screwed fastening screws, wherein also the ones on the back and with screw domes 43 screwed cover caps 16 by pinching the Ensure that the door leaf is attached to the door plate 10.

Is arranged behind the sliding cap 15 Locking device actuated, so the movement of the Closing thumb, not shown, along the associated Actuating surface 35 of the locking plate 33, the locking plate moved against the action of the spring 40 so that the Latch projection 41 releases the hook 66 of the handle 13 and the handle 13 from the plane of the door plate 10 below the action of the spring 24 folds out. After that, the Handle 13 and taken to the level of Door plate 10 parallel plane can be pivoted.

This pivoting is converted into a rotary movement of the Pinion 18, which moves the rack 25, the in turn the bolt mechanism 63 connected to it of their displacement.

The peculiarity of the closure device is in addition to the Assignment of the first and second door plate area in it that the moving parts such as handle, hinge pin, pinion and rack each hold itself or from the nose 34 of the locking plate 33 are fixed, so that only the Bolt plate 33 is to be screwed to the door plate 10. Should that in the illustration in Fig. 1 on a right hinged door mounted door plate 10 either by turning the door leaf or by converting the Door sign set up for a left-hinged door , it is only necessary to use the handle 13 can be seen from the door plate 10 and after rotation by 180 ° reinstall, due to the symmetrical structure all existing inside the door plate 10 Functional parts such as pinions, racks, etc. no other Adjustments are required. The modification of the handle can made from the front of the door plate be that in the extended position of the handle the axis 23 from the projection 21 of the pinion 18th is removed, whereby the hinge pin 22 as well as the Handle 13 free from the pinion 18; after turning the Door plate 10 only needs the hinge pin in that opposite pinion 18 inserted and together with the handle 13 by inserting the axis 23 in the Projection 21 of the other pinion 18 are assembled. In the same way, the conversion of the locking device in be made in a simple manner that the Blind cap 14 as well as the sliding cap 15 from the Guide slots 45 of the openings 44 removed become. After unscrewing the two caps 16 the support bracket 37 is removed from the door plate 10 and in a 180 ° offset position of the door plate 10 in Area of the other opening 44 are pushed so that the locking device in the form of a not shown Cylinder lock can be used and fixed in it. To Unscrew the cover caps 16 and insert them of blind cap 14 and sliding cap 15 is the Locking device ready for use again.

The closure device described above is therefore for installation in cabinets or housings with different Suitable height because a total of three in the rack 25 Connection openings 29 for coupling the locking mechanism 63 are trained. Because with a smaller one Cabinet or housing only correspondingly short Locking bars used as locking mechanism 63, so can this to the middle connection opening 29th be connected. In the case of a correspondingly high one Cabinet or housing can be shorter locking bars than Bolt mechanism 63 in the respective outer connection openings 29 of the rack 25 are connected, so that also larger cabinet height the use of shorter Locking rods as locking mechanism 63 is made possible.
