Description

The invention is based on a locking device for a switch cabinet, with a lock door and a side door, with the side door on one of its hinge side opposite vertical outer edge a U-profile formed on a door leaf of the side door with an opposite to the door leaf in the switch cabinet interior and set back the door leaf has open receptacle for a lock mechanism of the castle door. Such a locking device is from DE 198 06 064 C1 known. A similar locking device also describes the DE 199 46 773 C2 .

The locking devices of the type described above known from the prior art have the disadvantage that the mechanism to be manually operated for locking the side door is only inadequately accessible when the lock door is open, which is particularly due to the fact that the mechanism for operating the side door lock is manually closed pivoting lever is arranged on a side of the side door facing the switch cabinet interior and is therefore not visible to the user.

It is therefore the object of the invention to further develop a locking device of the type described at the beginning in such a way that it is comfortable to use.

This object is achieved by a locking device with the features of claim 1. The independent claim 16 relates to a corresponding switch cabinet. Exemplary embodiments are the subject of the dependent claims.

Accordingly, it is provided that on an outer free profile side of the U-profile, a pivot lever of a locking device for the side door is fastened so that it can pivot about an axis of rotation between an open position and a closed position.

The outer free profile side can in particular be an outer end face of the side door, which extends at a right or an obtuse angle to the door leaf of the side door. When the swivel lever of the side door lock is around the The axis of rotation is displaceable between the open position and the closed position, this axis of rotation can in particular extend perpendicular to the end face, so that the pivot lever between the open position and the closed position is also essentially at right angles or at an obtuse angle to the plane of the door leaf of the side door emotional. The pivot lever is thus accessible in every setting position from the front of the locking device, in particular also from the front of a control cabinet, and, unlike the arrangement known from the prior art, is not covered by the side door. The pivot lever can be pivotable in a plane between the open position and the closed position, which plane extends parallel to the free profile side. In particular, the axis of rotation can extend perpendicular to the free profile side.

The free profile side can run at least approximately perpendicularly or at an obtuse angle to the door leaf.

In the open position, the pivot lever can extend beyond the door leaf plane to the front of the side door. Furthermore, the pivot lever can be arranged completely behind the door leaf plane in the closing lever position. In particular, the pivot lever can be positioned in front of the outer free profile side of the U-profile or the end face of the side door.

The locking of the side door can have a first and a second push rod, with which the pivot lever is mechanically coupled via a scissor link, wherein the push rods extend along an outer side of a further profile side of the U-profile which is arranged on the rear side of the side door and which extends over a fold is formed on the outer free profile side of the U-profile.

The U-profile can be formed in one piece with the door leaf of the side door. In particular, the U-profile can be formed by folding the door leaf of the side door on the vertical longitudinal edge of the side door opposite the hinge side of the side door. The U-profile can be formed, for example, by three successive 90 ° folds and / or obtuse-angled folds of the door leaf. A suitable U-profile, which is formed in one piece with the door leaf of the side door, is from the DE 198 06 064 C1 known.

The locking of the side door can have a first and a second push rod, with which the pivot lever is mechanically coupled via a scissor link, with a first toggle lever of the scissor link at opposite ends via a first rotary connector to the first push rod and the pivot lever and a second toggle lever of the Scissor link is connected at opposite ends via a second rotary connector with the second push rod and the pivot lever.

In each setting position of the pivot lever, at least one of the toggle levers can overlap over its entire length with the outer free profile side of the U-profile or with a clamping protection panel fixed on this and protruding beyond it.

At least one of the toggle levers can be made in several parts or in one part. The toggle lever can have a toggle lever rod and a V-shaped clamping protection cover. The protective cover panel can be integrally formed on the toggle lever rod or can be detachably connected to the toggle lever rod. The releasable connection can be, for example, a clip or plug connection. The releasably connectable anti-clamping panel can in particular be a molded plastic part. The anti-pinch cover is intended in particular to prevent fingers from being trapped during the adjustment of the pivot lever between the open position and the closed position when the toggle rods of the scissor link are pivoted with a varying overlap between the toggle rod and the outer free profile side of the U-profile with respect to the outer free profile side .

The toggle levers can each be connected to the respective push rod via an L-shaped coupling piece. The coupling piece can have a first fastening side, which extends parallel to the outer free profile side of the U-profile and has the rotary connector. The coupling piece can furthermore have a second fastening side which is connected to the push rod and extends parallel to an outer side of a further profile side of the U-shaped profile arranged on the rear side of the side door.

A protective cover panel can be fixed to the U-profile and extend parallel to the outer free profile side of the U-profile and protrude from the U-profile.

In the open position of the pivot lever, a first of the toggle levers can extend parallel to the outer free profile side of the U-profile and protrude from the rear of the U-profile.

Furthermore, in the open position of the pivot lever, a second toggle lever can extend parallel to the outer free profile side of the U-profile and protrude over the front of the U-profile.

The toggle levers can be attached to the swivel lever opposite to the axis of rotation of the swivel lever, further axes of rotation of the rotary connectors connecting the toggle levers to the swivel lever being arranged between the toggle levers and the swivel lever parallel to the axis of rotation of the swivel lever.

The other axes of rotation can be arranged opposite the door leaf in the open position of the pivot lever and protrude on opposite sides of the door leaf and the U-profile, the other axes of rotation in the closed position of the pivot lever of the outer free profile side of the U-profile are upstream.

According to another aspect, a switchgear cabinet is described which has a locking device of the type described above, the lock door and the side door being hinged to opposite vertical profiles of a frame of the control cabinet, wherein in a closed position of the lock door and side door the receptacle of the side door is covered by the lock door is. A suitable switch cabinet frame and suitable hinges for hinging the lock door and side door to the vertical profiles of the frame are from the DE 2016 10 117 378 B3 known.

The frame can have a horizontal strut that connects opposite ends of the vertical profiles with each other, with a sealing center piece with a profile receptacle open to the outside of the frame being attached to the horizontal strut, and with a sealing element being received in the profile receptacle, which attaches the U-profile to a seals their longitudinal ends against the profile holder.

The center seal piece can be fastened to a Z-fold of the horizontal strut, an upper horizontal profile side of the Z-fold having a system perforation made up of regularly spaced fastening receptacles, the center seal piece having a passage aligned with one of the fastening receptacles for the free end of a push rod of the lock, and wherein the free end in the closed position of the pivot lever extends through the passage and the aligned fastening receptacle into the horizontal strut. In the open position, the free end can be completely removed from the fastening receptacle and the aligned passage so that the side door is unlocked from the frame and can be pivoted away from it.

The sealing center piece can have a hard component having the profile receptacle and a soft component forming the sealing element. The sealing element can line the profile receptacle along its inner circumference, the sealing element having a plurality of sealing lips which are spaced parallel to one another and protrude horizontally from the inner circumference.

On a side facing the interior of the frame, the profile receptacle can have a cutout into which a portion of the sealing element projects.

The hard component can have a passage for the free end of the push rod of the lock that is aligned with one of the fastening receptacles of a horizontal profile of the rack. The passage can be delimited by at least one horizontal inlet guide and preferably has two parallel inlet guides so that the free end of the push rod is guided in the horizontal direction, for example to provide tolerance compensation for the overall system. As a result, manufacturing tolerances of the control cabinet, in particular of the frame and the locking system, can be compensated.

The passage can furthermore have a run-on slope extending perpendicular to the horizontal inlet guide and at an acute angle to the horizontal for the purpose of sealing the seal.

The hard component can have a centering dome on its rear side facing the vertical profile, via which the hard component can be inserted into a fastening receptacle the horizontal strut engages so that the hard component is pre-positioned with respect to the horizontal strut.

The hard component can furthermore have an essentially U-shaped clamping contour with which the hard component engages around a profile web of the horizontal strut, so that the hard component is oriented in a direction perpendicular to the horizontal strut.

The soft component can have several, in particular four, slats for sealing the switchgear cabinet, three of the slats being designed for direct contact with the U-profile formed on the side door.

A division of the locking force through offset contact of the lamellae on the U-profile can be achieved in that the lamellae have different lamella lengths, with lengths falling in the vertical direction from a first of the lamellae to a third of the lamellae.

By inclining the slats, for example inclined by 18 ° to the horizontal, a reproducible slat system can be achieved with the door closed. In particular, this ensures that the lamellas always lie against the incoming water radiation and are therefore pressed against the door when exposed to water, so that an increased sealing effect is achieved. The free end faces of the sealing lamellae can have a wave contour.

A fourth lamella can extend over a door panel of the side door and in particular serve to keep water from entering from the bottom side or from the roof side of the switch cabinet. For this purpose, the lamella rests on the door panel under water pressure and thus closes or covers the U-shaped receptacle for the soft component.

Double sealing lips can be provided for increased IP protection. Furthermore, a form fit between the soft component and the hard component can be produced, so that an increase in the soft component adhesion and the dimensional stability in the critical sealing area is achieved.

Figure 7

a detailed view of a further embodiment of a locking device according to the invention.

In the Figure 1 The locking device shown for a switchgear cabinet is shown without the lock door 1 complementary to the side door 2 shown to simplify the illustration. The side door 2 is designed as a shaped sheet metal part with a door leaf 6, on the vertical longitudinal edge of which a U-profile 7 is formed in one piece, in particular bent from the door leaf 6. Such a side door 2 is for example from the DE 198 06 064 C1 known.

On an outer end face the U-profile 7 has an outer free profile side 10, to which the pivot lever 11 can be pivoted parallel between an open position and a closed position of the locking mechanism 12 of the side door 2. In particular, the pivot lever 11 can be rotated about an axis of rotation x which extends perpendicular to the outer free profile side 10 of the U-profile 7.

With reference to the axes of rotation x, which are located upstream and downstream of the axis of rotation y, a respective toggle lever 15 is fixed on the pivot lever 11 so that it can rotate relative to the pivot lever 11 via a pivot connector 16. The two toggle levers 15 are connected at their ends facing away from the pivoting lever 11 via a further rotary connector 16 to a coupling piece 19, via which the toggle levers 15 are each coupled to a push rod which is arranged on the rear of the U-profile 7. While the push rod mechanism, as in the case of the locking devices known from the prior art, is further arranged on the side of the side door facing the inside of the switch cabinet, the side door lock 12 and in particular the pivot lever 11 is accessible via the front of the side door 2, so that the side door 2 is easy to use.

With reference to the Figures 2 and 3 further details of the in Figure 1 locking device shown clearly. In particular, in the open position of the side door lock 12, the toggle lever 15 protruding beyond the front side of the side door 2 has a clamping protection panel 17 formed on a toggle lever rod 18 of the toggle lever 15. The protective cover 17 covers, as in Figure 2 can be seen, that area which between the outer free profile side 10 of the U-profile 7, the protruding over the front of the side door 2 toggle lever rod 18 and the pivot lever 11 to pinch fingers when giving away the pivot lever 11 and thus a shift to prevent said components of the scissors member 14 from each other.

On the outside 3 of the further profile side 22 of the U-profile 7 facing the switch cabinet interior, a further clamping protection 17 is attached, which extends beyond the outside 3 and thus in the installation situation in the direction of the switch cabinet interior. The further clamping protection panel 17 can be fastened to the U-profile 7, for example screwed to the further profile side 22 of the U-profile 7.

Figure 2 It can also be seen that the push rods 13 are fixed to the further profile side 22 of the U-profile 7 via a weld-on bolt 9, the push rods 13 having an elongated hole in an end area over which they are placed on the bolt 9 via a keyhole, along which the respective push rod 13 can be displaced via the respective bolt 9. Further details can be found in Figure 3 shown.

The two toggle levers 15 are each connected to the push rod via an L-shaped coupling piece 19. While the toggle levers 15 are pivotable in a plane that extends parallel to the outer free profile side 10 of the U-profile 7, the translational linear movement achieved with the help of the scissors member 14 is shifted into a plane via the L-shaped coupling pieces 19 extends along the outside 3 of the further profile side 22 of the U-profile 7 on the rear side of the side door 2. In this way, it is possible that, with the push rod mechanism still concealed behind the side door 2, the pivot lever 11 itself can be arranged in front of the side door 2 and can thus be easily accessible to a user. The synopsis of Figures 1 to 3 It can also be seen that the embodiment shown is implemented with the aid of simple technical means. The L-shaped coupling pieces can also be designed, for example, as simple, folded sheet metal parts.

The Figure 4 shows an exemplary embodiment of a switch cabinet 100 in the area of the floor frame of the rack 110. The floor frame has a front horizontal strut 120 which delimits the door-side opening of the rack 110 on the floor. The castle door 1 and the side door 3 are hinged to opposite vertical profiles (not shown) of the frame 110, as shown, for example, from FIG DE 10 2016 117 378 B3 is known.

The horizontal strut 120 of the rack 110 connects the opposite ends of the vertical profiles to one another and has a sealing center piece 200 which is fastened to the horizontal strut 120 with a profile receptacle 210 open to the outside of the rack 110. A sealing element 220 is received in the profile holder 210, which seals the U-profile 7 of the side door 3 at its bottom-side longitudinal end with respect to the profile holder 210.

A suitable floor frame is, for example, from DE 10 2015 121 193 B4 known. The horizontal strut 120 of the in Figure 4 The embodiment shown is designed accordingly and accordingly has a Z-edging 121 on its outer circumference, via which the central sealing piece 200 is fastened to the horizontal strut 120. Furthermore, an upper horizontal profile side 122 of the Z-edging 121 has a system perforation made of regularly spaced fastening receptacles 123. The center seal piece 200 has a passage 230, which is aligned with one of the fastening receptacles 123, for the free end of the push rod 13 of the lock 12, the free end of the push rod 13 in the closed position extending through the passage 230 and the aligned fastening receptacle 123 into the horizontal strut 120 extends and thus locks the side door with respect to the frame.

As in Figure 5 As can be seen, the passage 230 has a bevel 270 which the free end of the push rod meets when the push rod 13 is transferred from its release position into the closed position. The U-profile 7 is pressed further into the profile receptacle 210 under the pretension of the sealing element 220, the sealing element 220 being compressed and thus an effective sealing of the U-profile 7 of the side door 3 against the frame is achieved.

The sealing center piece 200 can in particular be designed as a molded plastic part and the sealing element 220 can line the profile receptacle 210 along its inner circumference. The sealing element 220 has a plurality of sealing lips 240 spaced parallel to one another and protruding horizontally from the inner circumference.

The synopsis of Figures 4 and 5 It can also be seen that the sealing element 220 has a sealing web 260 opposite each other at its end protruding from the profile receptacle 210, with which the sealing center piece 200 in the FIG Figure 4 The closed position of the side door 2 shown is sealed against a seal 24 applied to the inside of the side door 2.

Similarly, a further sealing center piece can be arranged on an upper horizontal strut of the frame, which seals the U-profile 7 at its upper end with respect to the frame. With the help of the seal center pieces and the seal 24 applied to the inside of the door, a circumferential closed sealing of the control cabinet door side against the control cabinet frame can be achieved.

In Figure 6 An embodiment of a locking device is shown in the closed position, in which all components of the scissor link, in particular the two toggle levers 15 and the pivot lever 11 itself, are arranged in alignment with the outer free profile side 10 of the U-profile 7 and thus in a space-saving manner, so that On the one hand, when the lock door of the locking device is closed, the side door lock 12 cannot collide with the lock door and, on the other hand, the elements of the scissor link 14 cannot protrude into the installation space of the switch cabinet housing and collide there with switch cabinet fittings. The only elements of the locking device that protrude beyond the push rod mechanism into the interior of the switch cabinet housing are the anti-trap covers 17. In one embodiment, these can be detachably connected to the toggle rod 18 or the U-profile 7, so that in the application where there is a risk of collision exists between the anti-trap screens 17 and built-in switch cabinets, the use of the anti-trap screens 17 can be dispensed with at the expense of the anti-trap protection.

A tubular door frame 23 is arranged on the inside of the door of the castle door 1 and side door 2, the tubular door frame 23 on the castle door being arranged in such a way that in the in Figure 6 Shown closed position of side door 2 and lock door 1 between the outer free profile side 10 of the U-profile 7 and the tubular door frame 23, sufficient space is created to accommodate the side door lock 12 between the tubular door frame 23 and the outer free profile side 10 in the closed position of the side door lock 12 to be able to.

Regarding Figure 7 the attachment of the push rod mechanism to the outside 3 of the further profile side 22 of the U-profile 7 is shown. On the outside 3, welding studs 9 are fixed on the further profile side 22, on which in turn the push rods are placed via a keyhole-shaped elongated hole. In order to avoid detachment of the push rods 13 from the bolt 9, the push rods are secured by a securing attachment 25 placed on the bolts, which additionally has the function of a stop by, like the lower detailed view of Figure 7 shows, engages in the elongated keyhole 26, so that the portion of the safety attachment 25 engaging in the hole 26 forms a stop which prevents the bolt 9 from being aligned with the wide end of the keyhole 26 and thus a detachment of the push rod 13 would be possible.
