locking system

The invention relates to a closure system for closing a first element, in particular a panel door to a second element, in particular a panel body of a panel, with a to the first member to buildin ^¬ righting first closure member having a member driven by a drive pinion and a first Verriegelungsmit ^¬ tel having a second fastener to be fastened to the second closure part, which has a first locking ^¬ medium associated second locking means, where ^¬ in a driven by means of the pinion rack on which one of the two locking means is arranged to the one ^{¬ handle of} the one of the two locking means with the other of the two locking means by the pinion from an open position to a closed position is displaceable.

Such a closure system is known, for example, from the publications EP 0 261 265 A1 and EP 0 261 267 B1. In these known closure systems, the first element of a metal cabinet door and the second element of ei ^¬ nem cabinet body are formed. The sheet metal cabinet door assigned designated first locking means in the form of a Doppelrollzap ^¬ fens is arranged on the rack, which is displaceably held on the inside of the sheet metal cabinet door. The second locking means in the form of a hook-like projection assigned to the cabinet body is screwed to the cabinet body.

The object of the invention is a closure system with the features of the preamble of claim 1 (EP 0 261 265 Al; EP 0 261 267 B1) to the effect that the first element is relieved.

This output is achieved according to the invention in that the second locking means is arranged on the rack.

By arranging the second locking means on the rack is now also the rack element EIe- the second (in particular in the form of a panel body) zugeord ^¬ net. This leads to a substantial relief of the first element (in particular in the form of a panel door). This can prevent warping and twisting of the first element and thus its stability can be improved. At the same time, the modifications necessary for retrofitting the locking system, which must be carried out on the first element (in particular a control panel door), are reduced.

To reduce the number of components of the new closure system, it is advantageous if two guide slots of the rack are provided as the second Verriege ^¬ ment. In this case, the assigned first locking means can then be a locking ^pin held on the drive element.

To simplify the production of the rack is provided that it consists of two sheet metal parts, where it is to increase the stability of the new closure system of ^¬ part, when the two sheet metal parts bent U-shaped and are non-rotatably nested in three mutually perpendicular directions of rotation ,

For simple, secure storage and management of the rack on the second element is provided, this at one on the to guide the second element to be fastened holding part slidably.

For example, management is also a large sheet-shaped first EIe- reliably sealed to the second member, the rack is advantageously provided to be coupled by means of a first Kop ^¬ pelstange with a second rack and / or by means of a second coupling rod with a third toothed rack. In this case, the second and / or third rack may be coupled to further racks by means of further coupling rods.

In order to keep the required variety of parts of the new Verschlusssys ^{¬ system} as low as possible, the racks form identical and each as a component of each of a second closure member to be slidably guided on a to be attached to the second ele ^¬ ment holding part. Thus, in a simple manner, the second locking means of each of the racks can then interact in each case with a first locking means of a first closure part. In this case, only one of the first locking parts with the on ^¬ drive element, the pinion and to the drive member rotatably coupled driver for receiving a supply ^¬ Actuate the key needs to be provided.

The first closure parts, which have no drive element and no pinion, may be provided with a blanking plug instead of the carrier, in order to indicate to the operator that no actuation is required here.

In order to reliably prevent the operation of the blind plugs these are provided with two cylindrical pins for ^torsionally holding on the first element. To relieve pressure in case of failure, it is particularly advantageous when using the new closure system in switching fields when each of the second closure parts having Federele ^¬ ment provided fastening means which serve for resilient storage of the holding parts on the second element.

The new locking system can be used, in particular, with panels having a panel body and a panel door in order to close the panel door on the panel body.

In this case, the second closure parts can be ^fastened both on the left and on the right front side of the panel body, and therefore the new closure system can be used both for left and right side panel doors.

The invention will be explained nä ^¬ forth her for better understanding of ^¬ hand illustrated in the drawing, the scope of the invention not limiting embodiment. Showing:

FIG. 30 shows the hinge system of the power distribution unit according to FIG. 3.

FIGS. 1 and 2 show a frame of a switching field 1 of a switchgear known as a point distributor in power distribution technology. The panel consists of a switching ^¬ field carcass 2 and a panel door 3. The panel body 2 is cuboid and consists of a rear, horizontally extending frame sections 4, two front, horizontally extending frame sections 5 and 6 and a vertically extending rear wall 7 and two vertically extending side walls 8 and 9 in the form of Beplankungsblechen. The side walls 8 and 9 have bends 10 to 13 and 14 to 17, which serve for connection to the frame profiles 4 to 6 and the rear wall 7. The rear wall 7 has a fold 18 for connection to the side walls 8 and 9.

According to FIG. 3, a hinge system 19 for hinging the panel door 3 is provided on the left front side of the control panel 1. This hinge system 19 consists of a lower first door hinge 20 and an upper second door hinge 21. In this case, according to FIG. 30, each of the two door hinges 20, 21 has a first hinge part 22a associated with the control panel door 3; 22b, a second hinge part 23a associated with the panel body; 23b and a hinge pin 24a; 24b on. In this case, the first hinge part 22a; 22b two Schrau ^¬ ben 25a; 25b at the panel door and the second hinge part 23a; 23b via a screw 26a; 26b attached to the panel ^¬ corpus 2.

Further, according to the figure 3, a closure system 27 is arranged in the form of a bar lock on the right front side of the panel 1, that is composed of a lower first lock ^¬ part 28, an upper second lock part 29 and a Kop ^¬ pelstange 30th

In the figure 4, showing the lower lock member 28 of the new fastening system, there is a attached to the compartment door 3 lower first closure member 31 from a Roset ^¬ te 32a, a blanking plug 33 (see also FIG. 28), an Fe of the disc 34a, a tensioning pulley 35a, a two-part locking pin 36a, a bolt 38a provided for receiving the locking pin 36a with a through hole 37a, a cylindrical pin 39a for fixing the blind plug 33a to the bolt 38a and two cylinder pins 40 for axially fixing the blind plug 33 to the panel door 3. The cylindrical pin 39a passes through through holes 41a, 42a of the dummy plug 33a or of the bolt 38a, which is inserted axially into the blind plug (see also FIG.

A lower second closure part 43a fastened to the panel body 2 consists of a holding part 44a, a toothed rack 45a in the form of a striking plate composed of two sheet metal parts 46a, 47a, two retaining bolts 49a provided with spring elements 48a in the form of helical springs for fastening. tion of the holding part 44a on the outside of the fold 14 and a closure piece 50a. In this case, both ends of the retaining bolts 49a are each provided with a collar 51a and 52a. The one collar 51a serves in each case as an abutment for one of the spring elements 48a, while the other collar 52a is supported on the front side of a base portion 53a of the holding part 44a resting against the fold 14. In this case, the holding part in this portion 53a for introducing the unte ^¬ ren the two retaining bolts 49a on a downwardly open long hole 54a (see FIGS. 11 and 12). To insert the upper of the two bolts is a slot 55 a, which has adapted to the cross section of the collar ^{52 a} circle ^¬ shaped extension 56 a at the lower end. The retaining bolts 49 a are therefore each guided from the inside of the fold 14 forth through a hole 57 a system perforations before they are passed through the holding part, with which the folds 10 and 14 of the side walls are provided. For positioning of the holding part at the fold during assembly, the holding ^¬ part has a facing the front of the fold nose 74a, which engages in a hole 57a of the system perforations.

The two sheet metal parts 46a, 47a, which form the rack 45a (the striking plate), each have an L-shaped guide slot 58a for guiding the locking pin 36a, with a first guide section 59a of the guide slots perpendicular and a second guide section 60a parallel to the front side runs. The holding part 44a, which serves to guide the rack 45a (the striking plate) vertically and thus parallel to the front side, has two perpendicularly projecting from its base portion 53a side portions 61a and 62a, the end a U-shaped guide groove 63a and 64a for the Sheet metal parts 46a and 47a form. Since the base portion 53a of the holding part 44a forms further guide surfaces 65a and 66a and 67a and 68a for the sheet metal parts 46a and 47a, these are only vertically displaceable, but set horizontally with a certain play by the holding part. The Seitenab ^¬ sections 61a and 62a of the holding part are provided for inserting the locking pin 36a with front open, window-like recesses 69a and 70a, which are so large that a horizontally inserted locking pin 36a in its Betä ^¬ tion in the clockwise direction freely rotatable by 90 ° is. The rack 45a (the strike plate) is in two ^parts only for easy ^¬ ren production. However, it can also be in one piece, for example, bent from a single sheet metal part. The two sheet metal parts 46a, 47a are nested in one another that they have a shorter sleeve of rectangular cross section bil ^¬. They have both parallel to the front side and in the two directions transverse to the front side extending, mutually associated stop surfaces 71a, 72a; 73a on to prevent mutual rotation of the sheet metal parts.

Referring to FIG. 5, which shows the upper lock part 29 of the new lock system 27, another upper first lock part 75 fixed to the panel door 3 consists essentially of the same parts as the lower first lock part 31 with the following exceptions:

Instead of the dummy plug 33a, the upper first closure part 75 has a driver 76 (see also FIG. 29), which is provided with a wing-like recess 77 for receiving an actuating key (not shown). It lacks the cylindrical pins 40, which are provided in the lower first Ver ^¬-circuit part 31 to set the blanking plug 33rd On the free end of the bolt 38b of the upper first closure member 75, a drive element 78 is mounted in the form of a drive pin which is penetrated transversely to its longitudinal axis of the two-piece locking pin 36b so that the two free ends of the locking pin 36b from the Protruding drive element 78 out. A provided with a square socket 79 pinion 80 is mounted on a Außenvierkant 81 of the drive member 78.

According to the figures 4 and 6 to 21, the lower first Ver ^¬ final part 31 is disposed so that its locking pin 36a assumes a horizontal position and into the guide portions 59a of the guide slots 58a of the holding portion 44a and in the front side open, window-like recesses 69a or 70a of the striking plate 47a engages.

The first upper shutter portion 75 is disposed ^¬ in a position in which its locking pin 36b assumes a vertical position. In this case, the wing-like recess 77 of the driver 76 assumes a vertical position. In this flügelar ^¬ term recess 77, the not shown in further 27 for actuating the new fastening system in accordance inserted ge ^¬ molded actuation key.

According to Figures 4 and 5, the blind plug 33 and the driver 76 each have a collar 82 and 83 (see also Figures 28 and 29), of a lip 84a; 84b (see Figure 26) of the associated rosette 32a; 32b is behind handles. This is the rosette 32a; 32b set captive, as soon as the first closure parts 31 and 75 are attached to the panel ^¬ door 3.

According to FIGS. 13 to 15, when the closure system 27 is mounted, the panel door 3 is located between the rosette 32a; 32b and the spring washer 34a; 34b. The tensioning pulley 35a; 35b engages with spring arms 85a; 85b into a groove 86a; 86b of the bolt 38a; 38b (see also Figure 27) and thus puts the first closure member 31; 75 fixed to the panel door 3. According to Figures 24 and 25, the cylindrical pins 40 engage in a wing-like recess 87 of the panel door 3, and thus set the blind plug 33 axially so that it is mounted against rotation on the panel door 3. An actuation of the dummy plug 33 is additionally prevented by the fact that this front only a small centric Ausneh ^¬ tion 88 has, so that here the operating key can not be inserted.

The upper second closure part 43b and the lower second

Locking part 43a are ^{miteinan ¬} connected by means of the coupling rod 30, which has at their free ends in each case a constriction 89, in the assembled state in each case an angled end 90a; 90b, 91a; 91b, 92a; 92b and 93a; 93b of the two sheet metal parts of the racks 45a; 45b (the closing ^¬ plates) engages. For this purpose, the sheet metal parts 46a; 46b, 47a; 47b each have a window-like opening 94a; 94b and 95a, respectively; 95b on. This window-like opening is for axial insertion of the coupling rod 30 with an adapted to the cross section of the coupling rod 30, parallel to the fold 14 of the side wall extending first opening portion 96a; 96b and with a transverse to this first opening portion 96a; 96b extending arcuate second opening portion 97a; 97b provided. Here, the second opening portion 97a; 97b shorter than the first opening portion 96a; 96b and adapted to the cross section of the constriction 89 of the coupling rod 30 so that the provided with the constriction 89 portion of the coupling rod is rotatable therein by 90 ° counterclockwise. Thus, the coupling rod 30 and the two sheet metal parts 46a; 46b, 47a; 47b firmly connected in the longitudinal direction of the Kop ^¬ pelstange.

Figures 16 to 21 illustrate how the new closure system ^¬ (bar lock) to operate that is, from an open position Position (Figure 22) in a closed position (Figure 20) can be transferred. In the mounted position, the pinion 80 of the upper first closure part 75 placed on the drive element 78 (drive pin) engages in a perforation of the rack 45b formed as a perforation 98b of the left-hand sheet metal part 46b (see FIG.

Upon rotation of the driver 76 of the upper lock member 29 by the operating key, not shown, also rotates the drive element 78 (the drive pin) and thus the pinion 80 and moves the hole provided with the hole 98b left sheet metal part 46b and nested with him right sheet metal part 47b of the rack 45b (of the striking plate) upwards. At the same time, the locking pin 36b rotates with the drive element 78 in its horizontal position and enters the longitudinal direction of the displacement of the coupling rod 30 extending second guide portions 60b of the guide ^¬ slots 58b (see Figures 17 to 21).

Due to the coupling of the racks 45b (the striking plates) of the upper 29 and the lower 28 lock part by means of the coupling rod 30 and the rack 45a of the lower lock member 28 is shifted upward. In this case, the locking pin 36a of the lower lock part 28 in the along the direction of displacement of the coupling rod 30 extending guide portion 60a of the rack 45a of the lower lock ^¬ part 28 enters, whereby the panel door is closed at the panel body over the lower 28 and the upper 29 lock part ,

Figures 22 us 23 show a closure system 127 with three cams 128, 129 and 199. In contrast to the Ver ^¬ circuit system 27 having two cams 28 and 29 (according to the figures 16 to 21) here is the second lock portion 129 is not provided with a closure piece, but at the lower end of a second coupling rod 130 coupled to the upper end of the third lock part 199 is coupled. The third lock part 199 has, like the first lock part 128, no driver, no drive element and no pinion.

Of course, the end pieces 50, 150 of the lower first 128 and / or third 199 lock part can be replaced by further coupling rods to couple even more lock parts.

The new locking system can be used both as a single and multiple closure, whereby its retrofitting can be done without replacing the system door. The position of the driving, that is provided with the driver, drive element and pinion lock part is freely selectable on the door.

Due to the resilient mounting of the holding parts on the control panel ^¬ corpus pressure relief is ensured especially when used in switchgear in case of failure on the panel door.

The number of lock parts is variable. Length-variable coupling elements allow use at different door heights.

Since the holding part can be attached to both the left and to the right front of the panel body without having to rotate the holding part, panel doors can be retrofitted without having to take into account a height offset from right to left attacking.
