Definitions

  • the invention relates to a mechanical and electrical locking device a motorized switchgear, which is a motor-driven shift knob, a mechanical blocking element interacting with the switching knob as well as one in the supply circuit of the motor Electric interlock switch used in the drive having.
  • a locking device is known for example from DE 694 06 026 T2.
  • the locking device known from DE 694 06 026 T2 has a locking member for mechanical and electrical Securing an engine drive block, which is essentially one retractable in the housing of the motor drive block Includes temple.
  • the bracket works directly with a shift knob and indirectly with a switch in the supply circuit of the Engine drive blocks together.
  • the invention is based, a particularly simple task and space-saving mechanical and electrical Locking device for a motor-operated Specify switching device.
  • This object is achieved according to the invention by a locking device with the features of claim 1.
  • This Locking device serves both mechanical and also the electrical locking of a switching device, which has a motor-driven shift knob. With the switching toggle acts mechanically a blocking element Locking device together, which is also the direct Actuation of one in the supply circuit of the motor Electric interlock switch used in the drive serves.
  • direct actuation of the electrical Switch by means of the mechanical blocking element is both a structurally simple and a space-saving Structure of the locking device given.
  • the locking device is preferably designed such that that the electrical interlock switch to the mechanical Blocking element is leading.
  • the blocking element If the blocking element is actuated, the switch toggle mechanically and electrically blocking, it is inevitable the mechanical blocking of the switching knob of the supply circuit the motor drive by opening the Locking switch electrically locked.
  • the leading Switching behavior of the electric interlock switch ensures that mechanically blocked Switch knob never with its electric drive Energy can be supplied.
  • the blocking element preferably has a first opening on, a fuse in the locked position of the shift knob by means of a lock, for example a padlock, allows.
  • a second opening in the blocking element is preferably provided for a sealing wire.
  • a Locking the blocking element in at least one locking position can be made possible by an appropriate locking device his.
  • the blocking element is by means of a manual actuation device and / or a tool-operated adjustment device actuated.
  • the manual actuator can when the blocking element is designed as a pivotable lever for example in the form of a handle molded onto the lever be realized.
  • the blocking element as rotatable Disc formed.
  • a flat disc is special easy to integrate into a device housing and projects independently of the switching position is not or not significantly over the housing contour out. An unintentional adjustment of the Disc is therefore, even if this is not by means of a Lock is determined, practically excluded.
  • a Locking function of the disc is preferably by means of a this cooperating or molded on this spring element given.
  • a display element is preferably integrated into the pane. Is an actuation of the disc exclusively or alternatively to manual operation using a tool provided, so the adjustment device for attachment of the tool also prefers the display element.
  • FIG 1 to 4 show a switching device 1 with an in not Shown in more detail, motor-driven switching knob 2, which is in the off position in the representations (FIG 1 and 3: front view; FIG 2 and 4: rear view). Only in the shown in all the FIG The switch toggle 2 is in the off position by means of a lever trained blocking element 3 can be blocked.
  • blocking element 3 has a projection 4, which engages behind a recess 5 of the shift knob 2 can. Is the blocking element 3 from the housing 6 of the switching device 1 swung out (FIG 1 and 2), so is a first opening 7 for a padlock and a second opening 8 for a sealing wire visible.
  • the control knob 2 is driven as a microswitch trained locking switch 9 used.
  • the Locking switch 9 is directly through the blocking element 3 operable, which is shown in more detail in FIG 5.
  • the Blocking element 3 essentially has an L-shaped outer contour on, with an upper edge 10 in the folded state of the blocking element 3, in which the shift knob 2 is released is (FIG 3 and 4), flush with an upper edge of the housing 11 of the switching device 1 completes.
  • the blocking element 3 is thus from the housing side edge 12 off accessible for manual operation.
  • the Handle 13 is on a lever arm 14 of the blocking element 3 integrally formed, which in addition two locking recesses 15 as Has latching devices, which are molded onto the housing 6 Interlocking spring 16 cooperate.
  • the blocking element 3 both in the position blocking the switching knob 2 (FIG 1 and 2) as well as in the releasing the switching knob 2 Position (FIG 3 and 4) can be locked.
  • Folding the blocking element 3 out of the housing 6 is only possible if the shift knob 2 in the shown off position.
  • the blocking element 3 first opens with the lever arm 14 cooperating locking switch 9 before the blocking element 3 the shift knob 2 mechanically blocked.
  • the electric interlock switch 9 it is excluded that a motor Actuation of the control knob 2 is started, if it is mechanically locked. The risk of damage of the switching device 1 by switching on the electrical Actuator despite mechanical blocking is therefore not given.
  • Switch toggle 2 shows in perspective the switching device 1, which for It is intended to be placed on a mounting rail.
  • a connecting rail 17 is pushed on, by means of which serves as a remote control unit Switchgear 1 with a switch that can also be placed on the mounting rail, generally contour-matched modular device is connectable.
  • FIG. 7 to 10 show a switching device 1 in a preferred alternative embodiment.
  • blocking element 3 is in this case as rotatable disc, which is parallel to the upper edge of the housing 11 arranged almost completely within the housing 6 is.
  • an actuator 13 here in the form of a corrugated edge of the disc 3, the housing side edge 12 facing. Due to the design of the blocking element 3 as a disc, however, this is independent of the switch position always practically completely in the contours of the switchgear 1 integrated. Accidental activity, such as it is easily possible, for example, by touching a lever would have to be in the case of the disk-shaped blocking element 3 should not be considered.
  • the disk-shaped blocking element 3 has on its circumference a projection 4, which is similar to the embodiment 1 to 6 of the locking of the shift knob 2 serves. Circumferential side of the disk-shaped blocking element 3 is also an arcuate spring element 18 as a locking device formed.
  • the elastic locking device 18 acts in a manner not shown with a rigid structure inside the housing 6 together.
  • a switching contour 19 which the direct actuation of the electric interlock switch 9 serves. As can also be seen from FIG. 11b, extends the switching contour 19 over a further angular range than the protrusion 4, with a leading switching behavior of the electric locking switch 9 in relation for the mechanical blocking function of the blocking element 3 is given.
  • FIGS 7 to 9 show the switching device 1 in three different Switching states.
  • An adjustment device 20 with a Slot 21 is arranged centrally on the blocking element 3 and accessible through an actuating opening 22 in the housing 6.
  • the adjustment device 20 is essentially as far from that flat blocking element 3 highlighted that its surface arranged approximately flush with the surface of the housing 6 is.
  • the slot 21 serves both for actuation by means of a Screwdriver and the display of the switching state of the Blocking element 3.
  • the switching device 1 is both electrical as well as manually switchable. Will the blocking element 3 rotated about 45 ° to the left is the switchgear 1 still switchable manually, i.e. the projection 4 is located not yet engaged with the shift knob 2, however electrically switched off, i.e. the lock switch 9 actuated by the blocking element 3 (FIG 8). With another Rotation of the blocking element 3 by 45 ° also occurs the mechanical Blocking of the toggle 2 in operation.
  • this Switching state (FIG 9) are through a housing recess 23 the openings 7, 8 for a padlock or a sealing wire accessible.
  • the spring element 18 causes a locking of the blocking element 3 in each of the 7 to 9 shown switching states.
