Definitions

• the invention relates to a retractable closure for doors of thin-walled switch cabinets in particular, with a trough to be placed on the front of the door leaf and set up for the retractable reception of a lever handle, the lever handle in the retracted position can be fixed via a locking device and via a release path from the retracted Position in an actuating position can be folded out of the trough and the further rotation of the lever handle can be implemented via an actuation path in the rotary movement of a locking rod which is guided longitudinally displaceably on the inside of the door leaf by engagement of its external toothing in rod recesses.
• a swivel lever lock with the aforementioned features is described in EP 0 261 266; in such, coupled with at least one locking rod Locks for driving the locking rod on the inside of the door is a lock case with a pinion mounted therein in a plane aligned parallel to the door leaf, the locking rod being guided through the lock case so that the engagement of the externally toothed pinion takes place in the rod recesses in the lock case .
• the pivoting lever mounted in the recess engages with its actuating shaft on the inside of the door leaf in the bearing bore of the pinion in the lock case and is therefore also pivotable in a plane aligned parallel to the door leaf to drive the pinion via its actuating path.
• the swivel lever can be folded out of its position in the trough via a release path from the trough into an actuating position.
• the basic idea of the invention is that the actuation path of the lever handle is set up in a plane perpendicular to the door leaf and that the pinion engaging in the rod recesses of the locking rod is mounted in the trough on the bearing axis of the lever handle and immediately forms a freewheel that bridges the release path of the lever handle is coupled to the rotary movement of the lever handle.
• the invention has the advantage that the pinion arranged perpendicular to the door leaf plane engages directly in the rod recesses, so that a separate lock case is completely avoided. Since the lever handle can only be rotated in one direction via the release path and its actuation path, which is activated in series, the storage of the lever handle in the recess is simplified.
• the pinion has an elongated hole and the lever handle has a pin which engages in the elongated hole of the pinion and is movable in the elongated hole.
• the freewheel between the lever handle and pinion can also be formed in the region of the common bearing axis, it being possible for corresponding rotary stops to be formed on adjoining rotary surfaces of the lever handle and pinion, which effect the entrainment effect following the release position of the lever handle.
• the lever handle is supported with respect to the pinion by a spring which prestresses the lever handle in its release position which is folded out of the recess.
• the pinion on its side facing away from the door leaf can have a flattened portion on which the compression spring located in a blind hole of the lever handle is supported. In the retracted position of the lever handle, this spring preload simultaneously loads the pinion into the closed position of the locking rod, so that the locking rod is fixed accordingly.
• a pin guide is assigned directly adjacent to the pinion, the pin guide being expediently arranged approximately in the center of the longitudinal extension of the lever handle in its folded position.
• This rod guide can be screwed to the trough by reaching through the door leaf; the rod guide can also be attached in one piece to the trough.
• a U-shaped hollow body and on the trough captive slide cap is provided, which to release the locking device in the longitudinal direction of the trough in the direction of the lever handle is displaceable with support on the door leaf.
• Fig. 1 a retractable mounted on a door leaf
• Fig. 2 shows the subject of Figure 1 in the
• Fig. 4 shows a trough as part of the closure shown in Figures 1 to 3 including rod guide mounted thereon in a single representation.
• a trough 11 can be fastened to a door leaf 10 on the outside thereof via fasteners 12.
• the trough 11 extends through the door leaf with an upper attachment 13 and with a lower attachment 1.
• a lever handle 15 is rotatably mounted in the trough 11 on a bearing axis 16 in such a way that the lever handle 15 is rotated in a plane perpendicular to the door leaf 10.
• a locking device 17 which acts on a lock 18 arranged in the trough 11 for the lever handle 15, so that the lever handle 15 can be fixed in the folded position via the locking device 17 .
• the locking device 17 is covered by a sliding cap 19 which is captively guided on the trough 11 and is designed as a U-shaped hollow body and which can be displaced to release the locking device 17 in the longitudinal direction of the trough, namely in the direction away from the lever handle 15, and thereby engages supports the door leaf 10 on the outside.
• a pinion 20 with an external toothing 21 is rotatably mounted in a plane oriented perpendicular to the door leaf 10, the external toothing 21 of which engages in rod recesses 23 of a longitudinally displaceable locking rod 22.
• the pinion 20 On its side facing away from the door leaf 10, the pinion 20 is provided with a flat 24, against which a compression spring 26 accommodated in a blind hole 25 of the lever handle 15 is supported in such a way that the lever handle 15 is preloaded from the folded position (FIG. 1) the actuation position (FIG. 2) results when the lever handle 15 is released from the trough 11 via the locking device 17 or the lock 18.
• the lever handle 15 and the pinion 20 are coupled to one another in their rotational movement perpendicular to the door leaf 10 via a freewheel, for which purpose the pinion 20 has an elongated hole 27 and the lever handle 15 has a pin 28 engaging in the elongated hole 27.
• the pin 28 is in the folded position of the lever handle 15 on the locking rod 22 facing the end of the elongated hole 27; If the lever handle 15 is released from the trough 11 via the locking device 17, the compression spring 26, when the pinion position is initially unchanged, ensures that the lever handle 15 folds out of the trough 11, the pin 28 seated on the lever handle 15 into the end position facing away from the locking rod 22 the slot 27 comes to rest. A further rotation of the lever handle 15 over its actuation path now leads to Driving the pinion 20 by the contact of the pin 28 at the associated end of the elongated hole 27, so that the pinion 20 rotates with the rotary movement of the lever handle 15 and thereby drives the locking rod 22.
• a pin guide 29 is provided immediately adjacent to the pinion 20, which is shown schematically in FIGS. 1 to 3 and according to the embodiment shown in FIG Door leaf 10 is attached to the trough 11 by means of an associated fastening 30.
