Definitions
- the invention relates to a lockable manually operated rotary drive for electrical switching devices, such as motor protection switch or smaller circuit breaker.
- Such rotary actuators are from the publications DE 1 200 923 B . DE 42 06 378 A1 and WO 97/28551 A1 known. These rotary actuators are connectable to an actuating axis for the switching device and equipped with a rotary handle, with a pivotable or displaceable locking member and with a Absch thoroughlyö réelle.
- the locking member cooperates in the Absch occidental ein with a locking element of a housing, on which the rotary handle is arranged.
- the locking member can be through the Abschrudö réelle closing means, in particular the bow of a U-lock or multiple U-locks, pass and thus complete the rotary drive and thus the switching device in the off position.
- the invention is therefore based on the object to protect the aforementioned rotary drive with simple means largely before the violent overcoming of the closed position.
- a well-known rotary actuators complementary and largely slipped over the rotary handle cap is adapted to the shape of the rotary handle and allows access to the at least one Absch.ö réelle to allow the hanging of the bracket of a U-lock for completing the rotary drive in the off state of the switching device.
- the turned-over protective cap is fixed in conjunction with the hinged bracket on the housing via a positive connection.
- a lockable rotary drive is created, which offers both a significantly lower attack surface and a much greater resistance to externally applied forces compared to an unprotected rotary drive with which an attempt is made to forcibly transfer the completed twist grip from the off position to the on position.
- the rotary drive according to the invention the safety in terms of overcoming the closed state and thus against dangerous consequences of vandalistic interventions is considerably increased, - are to be carried out from a conventional lockable rotary drive according to the prior art - only easy to implement measures without much cost.
- the housing with which the protective cap enters into the positive connection in an advantageous embodiment of the invention, that housing which is structurally associated with the rotary handle, or - if this structural association does not exist - which structurally combined either with the switching device to be actuated via the rotary drive or is as a separate housing, for example as an installation housing or as a control cabinet, mounted on the door of the rotary drive in the form of a door coupling rotary handle, the switching device surrounds.
- the protective cap is at least one Anformung from the protective cap on its rear facing the switching device, which engages in the over-slipped state of the cap each in a correspondingly shaped front molding in the housing, whereby the protective cap is fixed radially to the course of the actuating axis.
- the fixation of the protective cap in the axial direction causes the at least one U-lock in cooperation with the largely covering the rotary handle form of the protective cap.
- the protective cap engages with at least one of its side walls positively around at least one side wall of the housing.
- the protective cap with the rear end face of at least one of its side walls engages positively in at least one recessed on the front side of the housing groove.
- the protective cap is an injection molded part made of plastic or metal.
- a protective plastic cap is easy and cheap to manufacture.
- a protective metal cap provides even greater resistance to attacking forces, with no additional grounding required.
- Fig. 1 shows the lockable manually operated rotary drive 1, which is connected in the usual way via a back to be introduced into the rotary actuator 1 actuating axis with a switching device.
- the rotary drive 1 includes a box-shaped housing 3, on which a rotary handle 5 is mounted captive.
- the rotary handle 5 is pulled up on one side and has on this page three Absch thoughö réelleen 7 for attaching U-locks.
- the locking openings 7 are covered by a locking member 9 located in the rest position.
- the locking member 9 In the off position of the rotary handle 5, the locking member 9 in a known manner against in the housing 3 mounted spring means of the in Fig. 1 shown rest position in the direction of the axially extending direction arrow 11 in a Absch Strukturbericht ein slidably.
- the locking member 9 spent in the locking position causes the rotary handle 5 can not be rotated from the off position.
- Fig. 1 further shows a protective cap 13, which is largely slipped in the direction of the directional arrow 11 on the rotary handle 5.
- the protective cap 13 is an injection molded part made of plastic or metal.
- the protective cap 13 is adapted to the shape of the rotary handle 3 in such a way that it can largely cover the rotary handle 3, wherein the access for hanging U-locks in the Abschforö réelleen 7 is ensured by a rectangular recessed front release opening 15, such as Fig. 2 and Fig. 3 demonstrate.
- Fig. 2 shows that the rotary handle 3 is enclosed except for the region of the Abschforö réelleen 7 and the locking member 9 of the protective cap 13.
- the Absch apartö réelleen 7 are still blocked by the rest member located in the locking member 9.
- the locking member 9 has been moved to the Absch partners ein, so that the Abschforö réelleen 7 are now accessible. This can, as in Fig. 3 shown for the middle Absch forö réelle, the bracket 25 a padlock 27 are passed through.
- the rotary drive 1 is completed and connected to the rotary drive 1 switching device protected against switching.
- guard 13 of the rotary drive 1 is now protected to a much greater extent against violent transfer into the on state.
- the present invention is not limited to the embodiments described above, but also includes all the same in the context of the invention embodiments.
- the invention can be redesigned, for example, to the effect that instead of the interlocking projections 19 and protrusions 21 at least one of the lateral protective cap walls 29 with its rear end face 31 positively engages in a recessed on the front side 23 of the housing 3 groove (not shown). It is also possible that the protective cap 13 with its lateral protective cap walls 29 engages positively around the housing side walls 33 (also not shown).
- the invention described above finds application in the low-voltage technology for switching and protecting electrical drives and systems.
- the rotary drive according to the invention can be mounted, for example, on a control cabinet door, on the operating side of a control cabinet insert or an installation housing or directly on a switching device.
