Definitions
- the present invention relates to a circuit breaker blocking device, in particular a circuit breaker blocking device, comprising a base body with a first section, a second section and a recess formed between the first and the second section for receiving a switching lever, in particular a toggle lever, a circuit breaker, in particular a circuit breaker, a locking element mounted on the first section of the base body, in particular a locking screw, with an actuating section to fix the base body on a switching lever of a circuit breaker received in the recess, and a cover adjustably fastened to the base body between a release position and a lockout position , wherein the actuating section of the locking element is accessible for actuation in the release position and covered inaccessible for actuation by the cover in the locked-out position is, and wherein means are provided to fix the cover in the locked-out position by means of a locking element, in particular a shackle of a padlock, on the base body in order to block an adjustment of the cover from the locked-out
- a switching lever of a circuit breaker in particular a circuit breaker, which is in its position in which the circuit to be protected is switched off, in particular the tilt position, can be locked or secured by a person against actuation by a third party in order to be connected to the circuit To be able to carry out work without risk, ie without running the risk of the circuit being interrupted by another Person is accidentally reactivated or out of ignorance of the ongoing work.
- the switching lever of the circuit breaker is received in the recess of the base body of the circuit breaker locking device and then the base body is fixed to the switching lever or the circuit breaker by means of the locking element.
- the cover is then moved into its locked-out position so that the actuating section of the locking element is no longer accessible.
- the cover is fixed to the base body by means of a locking element, in particular a padlock or a bracket of a padlock, in order to block an adjustment of the cover from the locked-out position until the padlock is removed again.
- Such a circuit breaker locking device is from US 9,208,964 B2 known.
- the means for fixing the cover to the base body in the locked-out position consist in that two channels with two openings each run through the base body, which in the locked-out position of the cover are aligned with corresponding openings in the cover.
- one of the two channels runs horizontally between two lateral sides of the base body, and the other of the two channels runs transversely, from a side of the base body opposite the recess to an underside of the base body, so that in the locked-out position the Cover a padlock either in a horizontal position or in a vertical position, ie hanging down, can be suspended.
- the padlock When hung horizontally, however, the padlock takes up a lot of space in the horizontal direction, so that if there are several circuit breakers that are arranged directly next to one another, the attachment of the padlock is made more difficult by the adjacent circuit breakers and, due to lack of space, at least not all of the circuit breakers with such a circuit breaker Circuit breaker interlocking device can be provided.
- the bracket of the padlock With a vertical To hang up, the bracket of the padlock has to be threaded into the corresponding passage, which is comparatively laborious.
- the operation of such a circuit breaker locking device be it for a horizontal mounting or for a vertical mounting of a padlock, is not intuitive to the user.
- a circuit breaker locking device is from the document U.S. 5,500,495 A known.
- the invention is therefore based in particular on the object of creating a circuit breaker locking device of the type mentioned at the beginning, which facilitates the attachment of a padlock and enables intuitive operation.
- a circuit breaker locking device with the features of claim 1, and in particular in that the means include that the base body has a projection on a side opposite the recess, with which the base body in the locked-out position from the inside of the cover by an in the cover formed, in particular rectangular, recess extends through to the outside of the cover, the projection on the outside of the cover being provided with at least one passage through which a locking element can be passed, in particular in each case.
- the projection of the base body engages with the at least one passage through the cover to the outside, so that the at least one passage is particularly easily accessible and a locking element can be passed through particularly easily or a padlock can be attached particularly easily. Because the at least one passage is shifted away from the recess, there is also sufficient spatial distance to the respective circuit breaker when a padlock is hooked in so that it can be hooked in without hindrance.
- the projection can be kept particularly compact, so that in a position of use of the circuit breaker blocking device, it is horizontal aligned passage can be kept particularly short, so that even with a horizontal passage a padlock can be hung hanging down, with the result that more space is available for an adjacent circuit breaker for its own circuit breaker locking device. If, as an alternative or in addition, a vertically aligned passage is provided, a locking element, in particular a padlock, does not have to be laboriously threaded into it.
- a padlock hooked into a vertically oriented passage can be rotated on both sides in the hooked state, for example in order to be able to read an engraving on the lock body of the padlock in a targeted manner, for example, a conclusion about the owner of the padlock, ie the person who has the Exclusion of the circuit breaker has made, allowed.
- a padlock hung in this way can also be turned away in order to create space when an adjacent circuit breaker is to be accessed, in particular in order to also set a circuit breaker blocking device there.
- the at least one passage horizontally ie in particular from a first lateral side to a second lateral side of the projection , and / or vertically, ie in particular from one Top to a bottom of the projection, is aligned.
- a horizontal passage is useful, for example, if an engraving on the lock body should be able to be read without turning the padlock used. If several circuit breakers arranged directly next to one another are provided, each of which is to be provided with a circuit breaker blocking device, vertical passages are available to enable the padlocks to be hung next to one another without hindrance.
- a locking element can be a padlock, in particular a bracket of a padlock, wherein the bracket can be rigid or flexible, in particular as a cable bracket.
- a locking element can also be designed as a cable lock with a cable, in particular it is also possible that one cable is passed through the passages of several circuit breaker locking devices, so that several circuit breaker locking devices can be secured simultaneously with a single cable lock.
- the at least one passage comprises a first passage and a second passage, so that the user has several variants available for aligning a locking element to be used to fix the cover on the base body relative to the circuit breaker blocking device.
- the first passage and the second passage are a horizontal passage and a vertical passage as described above, or vice versa. In principle, it is conceivable that more than two passages are provided.
- first passage and the second passage intersect, since in this case the two passages take up as little space as possible.
- the diameter of the first, for example horizontal or vertical passage is smaller than the diameter of the second, for example vertical or horizontal passage.
- the diameter of the first passage and the diameter of the second passage can also be identical.
- an edge of the projection formed on an end facing upwards in the aforementioned position of use of the circuit breaker blocking device, on a side facing away from the recess has a bevel that extends into the vertically oriented passage, such that In the region of the bevel, a section of an opening edge of the vertically oriented passage is formed which defines a plane which is inclined with respect to the horizontal.
- the opening edge of the vertically aligned passage in the area of the bevel forms a particularly rounded receptacle for the shackle of a padlock.
- a padlock can hang in a defined position in the vertically oriented passage, which is particularly advantageous when there are several padlocks hanging next to one another.
- a bracket of a padlock is usually designed as a round bracket and can be received in a rounded receptacle in a particularly stable position.
- the padlock can be lifted slightly before turning.
- the first section of the base body can have a blocking section which shields the actuating section of the locking element from access from the recess side or from access from the recess side. Access from the otherwise open sides is shielded by moving the cover into its locked-out position.
- the cover is designed in such a way that it also shields the access on the recess side in its locked-out position.
- the cover can comprise at least one rear wall assigned to the side of the base body opposite the recess, a front wall assigned to the first section of the base body and two opposite side walls in order to cover the actuating section of the locking element inaccessibly in the locked position. This makes it possible to ensure in a simple manner that, in the locked position of the cover, the actuating section of the locking element is covered inaccessibly from the outside. It is preferred here if the recess is provided in the rear wall of the cover.
- the adjustable fastening of the cover to the base body comprises that the cover is fastened to the base body, in particular to the second section of the base body, pivotably between the release position and the lockout position via a pivoting device.
- a fastening can be implemented in a particularly simple manner, in particular in connection with the protrusion reaching through the recess formed in the cover.
- the cover can preferably be pivoted over a pivoting range of at least 45 °, in particular at least 90 °.
- the pivoting device can include that the cover has an opening in each of the two aforementioned, mutually opposite side walls and the second section of the base body on two mutually opposite lateral sides each has a pin which engages, in particular is latched, into a respective one of the two openings.
- the respective side wall of the cover can have a channel-shaped recess on its inside, one end of which into the respective opening opens and extends with its other end to an edge of the respective side wall.
- the two depressions run parallel to one another and at the same height.
- the two pins can each have a run-up slope for the side walls of the cover in order to make it easier for the cover to be pushed onto the base body.
- the two pins can, for example, each be designed so that they can be pushed back. When the two pins that are pushed back when the cover is pushed open have retracted as far as the openings at the end of the pushing-on process, they can extend there again in order to lock into the openings. According to another embodiment, however, the two pins are designed to be immovable, and the two side walls of the cover can be pushed apart. In particular in connection with this embodiment, it is preferred if at least the two side walls of the cover are designed to be resilient in order to enable the two side walls to be pushed apart when the cover is pushed onto the base body.
- the base body and / or the cover are designed as an injection-molded part and / or in one piece, so that the circuit breaker blocking device or its parts can be manufactured particularly easily or are.
- complex shapes can easily be produced with an injection molding process.
- the circuit breaker blocking device 9 shown in the figures can be fastened to a toggle switch lever 23 of a circuit breaker 25 in order to prevent the toggle switch lever 23 from being actuated (cf. Figures 3 and 4 ). This is particularly necessary when a person is working on a circuit and the circuit is switched off for this purpose by an associated circuit breaker and an unintentional switching on of the circuit breaker by a third party is to be prevented.
- the circuit breaker blocking device 9 shown comprises a base body 11, a locking screw 13 and an at least essentially box-shaped cover 15 (cf. Fig. 1 ).
- the base body 11 has a first section 17, a second section 19 and a recess 21 formed between the first section 17 and the second section 19 (cf. Fig. 6 ).
- the base body 11 and the cover 15 are each formed in one piece and are produced by an injection molding process.
- the circuit breaker blocking device 9 is shown in the figures in a position of use in which the first section 17 of the base body 11 is oriented upwards.
- the circuit breaker blocking device 9 can be attached to the toggle lever 23 of the circuit breaker 25 via the recess 21 and by means of the locking screw 13 (cf. Figures 3 and 4 ).
- the toggle lever 23 is first received in the recess 21 of the base body 11, which in particular runs obliquely to the horizontal.
- the base body 11 fixed to the toggle lever 23 by means of the locking screw 13, which is mounted on the first section 17 of the base body 11.
- the locking screw 13 has an actuating section arranged above the first section 17 in the form of a manually operable rotary knob 27 and a threaded shaft 29 firmly connected to it, which extends with its free end through the first section 17 into the recess 21.
- the locking screw 13 can be screwed further into the recess 21 in order to fix the circuit breaker locking device 9 on the circuit breaker 25.
- the locking screw 13 can be screwed back out of the recess 21 by turning the knob 27 in the opposite direction, whereby the fixing of the circuit breaker locking device 9 is released again.
- the cover 15 is pivotably attached to the first section 17 of the base body 11 via a pivot device 31.
- the cover 15 is between one in Fig. 1 release position shown and one in Fig. 2 lockout position shown adjustable.
- the rotary knob 27 of the locking screw 13 is accessible to a user.
- the rotary knob 27 is covered by the cover 15, and access to the rotary knob 27 is blocked for the user.
- the cover 15 can by means of the in Figures 3 and 4 Padlocks 35, 37 shown are fixed in the locked-out position on the base body 11, as will be explained in more detail below. This can prevent the cover 15 from moving out of the locked-out position according to FIG Fig. 2 in the release position according to Fig. 1 is adjusted.
- the rotary knob 27 of the locking screw 13 is therefore not accessible for actuation, ie the circuit breaker locking device 9 can no longer be removed from the circuit breaker 25, so that the toggle lever 23 is not actuated, in particular cannot be switched into its position in which the circuit to be monitored is switched on.
- the cover 15 has a rear wall 39 which, in the locked-out position, covers the side of the base body 11 opposite the recess 21, an end wall 41 which, in the locked-out position, covers the first section 17 of the base body 11, and two opposing side walls 43 (cf. . Fig. 7 ).
- the cover 15 also has a further end wall 61 opposite the end wall 41.
- the blocking of access to the rotary knob 27 by the cover 15 is supported by the fact that the first section 17 has a blocking section 33 in the direction of the side of the recess 21, which prevents the rotary knob 27 from being accessible from this direction.
- a particularly window-like recess 45 is provided (cf. Figures 7 and 8 ), through which a projection 47 (cf. Figures 5 and 6 ), which is formed on the side of the base body 11 opposite the recess 21, extends therethrough (cf. Fig. 5 ).
- a horizontal passage 49 with a first diameter and a vertical passage 51 with a comparatively larger second diameter are formed in the projection 47, which intersect approximately in the center of the projection 47 and through which a bracket of the padlock 35 and 37 respectively can be passed through, so that the cover 15 can be fixed in its locked-out position on the base body 11, ie can be blocked against being moved into the release position.
- the projection 47 according to Fig. 9 differs from that related to the Figures 1 to 8 projection 47 described in that it has a bevel 65 on its edge 63, which is formed on its upwardly directed end and on the side facing away from recess 21.
- the bevel 65 is designed in such a way that it extends into the vertical passage 51, so that the plane formed by the opening edge 67 of the vertical passage 51 formed in this area is positioned obliquely with respect to the horizontal.
- the opening edge 67 in this area therefore forms a rounded receptacle with a vertical component, into which a padlock bracket, which is usually designed as a round bracket, can be hung vertically in a defined position.
- the projection 47 in particular as shown in the figures, can be designed as an eyelet or in the manner of an eyelet, in particular as a double eyelet or in the manner of a double eyelet, and / or in the shape of a cylinder.
- the pivoting device 31 for the cover 15, in order to adjust it between the release position and the lock-out position, is formed in that an opening 53 is formed in each of the two side walls 43 of the cover 15, into which two pins 55 engage, which on two each other opposite lateral sides of the base body 11 are formed.
- the two side walls 43 are each provided on the inside with a channel-shaped recess 57, which extends between the respective opening 53 and a respective edge of the side wall 43, so that the respective pin 55 of the base body 11 to can be pushed into the respective opening 53 of the respective side wall 43 of the cover 15 in order to snap into place there.
- This is made possible in particular by the fact that the two side walls 43 of the cover 15 are designed to be resilient, so that they are pressed apart when the cover 15 is pushed onto the base body 11.
- the two pins 55 each have a run-up bevel 59 oriented in the direction of the respective channel-shaped recess 57.

Die vorliegende Erfindung betrifft eine Schutzschalter-Sperrvorrichtung, insbesondere eine Leistungsschutzschalter-Sperrvorrichtung, umfassend einen Grundkörper mit einem ersten Abschnitt, einem zweiten Abschnitt und einer zwischen dem ersten und dem zweiten Abschnitt ausgebildeten Ausnehmung zur Aufnahme eines Schalthebels, insbesondere eines Kippschalthebels, eines Schutzschalters, insbesondere eines Leistungsschutzschalters, ein an dem ersten Abschnitt des Grundkörpers montiertes Feststellelement, insbesondere eine Feststellschraube, mit einem Betätigungsabschnitt, um den Grundkörper an einem in der Ausnehmung aufgenommenen Schalthebel eines Schutzschalters zu fixieren, und eine an dem Grundkörper zwischen einer Freigabestellung und einer Aussperrstellung verstellbar befestigte Abdeckung, wobei der Betätigungsabschnitt des Feststellelements in der Freigabestellung für eine Betätigung zugänglich und in der Aussperrstellung von der Abdeckung für eine Betätigung unzugänglich abgedeckt ist, und wobei Mittel vorgesehen sind, um die Abdeckung in der Aussperrstellung mittels eines Verriegelungselements, insbesondere eines Bügels eines Vorhangschlosses, an dem Grundkörper festzusetzen, um ein Verstellen der Abdeckung aus der Aussperrstellung in die Freigabestellung zu blockieren.The present invention relates to a circuit breaker blocking device, in particular a circuit breaker blocking device, comprising a base body with a first section, a second section and a recess formed between the first and the second section for receiving a switching lever, in particular a toggle lever, a circuit breaker, in particular a circuit breaker, a locking element mounted on the first section of the base body, in particular a locking screw, with an actuating section to fix the base body on a switching lever of a circuit breaker received in the recess, and a cover adjustably fastened to the base body between a release position and a lockout position , wherein the actuating section of the locking element is accessible for actuation in the release position and covered inaccessible for actuation by the cover in the locked-out position is, and wherein means are provided to fix the cover in the locked-out position by means of a locking element, in particular a shackle of a padlock, on the base body in order to block an adjustment of the cover from the locked-out position into the release position.
Durch eine derartige Schutzschalter-Sperrvorrichtung kann ein Schalthebel eines Schutzschalters, insbesondere eines Leistungsschutzschalters, der sich in seiner den abzusichernden Stromkreis abschaltenden Position, insbesondere Kippposition, befindet, von einer Person gegen eine Betätigung durch einen Dritten gesperrt bzw. gesichert werden, um an dem Stromkreis gefahrlos Arbeiten vornehmen zu können, d.h. ohne dabei Gefahr zu laufen, dass der Stromkreis durch eine andere Person versehentlich bzw. aus Unwissenheit über die laufenden Arbeiten wieder aktiviert wird. Hierzu wird der Schalthebel des Schutzschalters in die Ausnehmung des Grundkörpers der Schutzschalter-Sperrvorrichtung aufgenommen und anschließend wird der Grundkörper mittels des Feststellelements an dem Schalthebel bzw. dem Schutzschalter fixiert. Danach wird die Abdeckung in ihre Aussperrstellung verstellt, so dass der Betätigungsabschnitt des Feststellelements nicht mehr zugänglich ist. Schließlich wird die Abdeckung in der Aussperrstellung mittels eines Verriegelungselements, insbesondere einem Vorhangschloss bzw. einem Bügel eines Vorhangschlosses, an dem Grundkörper festgesetzt, um ein Verstellen der Abdeckung aus der Aussperrstellung solange zu blockieren, bis das Vorhangschloss wieder abgenommen wird.By means of such a circuit breaker locking device, a switching lever of a circuit breaker, in particular a circuit breaker, which is in its position in which the circuit to be protected is switched off, in particular the tilt position, can be locked or secured by a person against actuation by a third party in order to be connected to the circuit To be able to carry out work without risk, ie without running the risk of the circuit being interrupted by another Person is accidentally reactivated or out of ignorance of the ongoing work. For this purpose, the switching lever of the circuit breaker is received in the recess of the base body of the circuit breaker locking device and then the base body is fixed to the switching lever or the circuit breaker by means of the locking element. The cover is then moved into its locked-out position so that the actuating section of the locking element is no longer accessible. Finally, in the locked-out position, the cover is fixed to the base body by means of a locking element, in particular a padlock or a bracket of a padlock, in order to block an adjustment of the cover from the locked-out position until the padlock is removed again.
Eine derartige Schutzschalter-Sperrvorrichtung ist aus der
Bei einem horizontalen Einhängen beansprucht das Vorhangschloss in horizontaler Richtung jedoch viel Platz, so dass bei Vorliegen mehrerer Schutzschalter, die unmittelbar nebeneinander angeordnet sind, die Anbringung des Vorhangschlosses durch die benachbarten Schutzschalter erschwert wird und aus Platzmangel unter Umständen zumindest nicht alle der Schutzschalter mit einer derartigen Schutzschalter-Sperrvorrichtung versehen werden können. Bei einem vertikalen Einhängen muss der Bügel des Vorhangschlosses vergleichsweise umständlich in den entsprechenden Durchgang eingefädelt werden. Im Übrigen erschließt sich die Bedienung einer derartigen Schutzschalter-Sperrvorrichtung, sei es für ein horizontales Einhängen oder für ein vertikales Einhängen eines Vorhangschlosses, dem Benutzer nicht intuitiv.When hung horizontally, however, the padlock takes up a lot of space in the horizontal direction, so that if there are several circuit breakers that are arranged directly next to one another, the attachment of the padlock is made more difficult by the adjacent circuit breakers and, due to lack of space, at least not all of the circuit breakers with such a circuit breaker Circuit breaker interlocking device can be provided. With a vertical To hang up, the bracket of the padlock has to be threaded into the corresponding passage, which is comparatively laborious. In addition, the operation of such a circuit breaker locking device, be it for a horizontal mounting or for a vertical mounting of a padlock, is not intuitive to the user.
Eine Schutzschalter-Sperrvorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus dem Dokument
Der Erfindung liegt daher insbesondere die Aufgabe zugrunde, eine Schutzschalter-Sperrvorrichtung der eingangs genannten Art zu schaffen, die die Anbringung eines Vorhangschlosses erleichtert sowie eine intuitive Bedienung ermöglicht.The invention is therefore based in particular on the object of creating a circuit breaker locking device of the type mentioned at the beginning, which facilitates the attachment of a padlock and enables intuitive operation.
Diese Aufgabe wird durch eine Schutzschalter-Sperrvorrichtung mit den Merkmalen des Anspruchs 1 gelöst, und insbesondere dadurch, dass die Mittel umfassen, dass der Grundkörper an einer der Ausnehmung gegenüberliegenden Seite eine Auskragung aufweist, mit der der Grundkörper in der Aussperrstellung von abdeckungsinnenseitig durch eine in der Abdeckung ausgebildete, insbesondere rechteckige, Aussparung nach abdeckungsaußenseitig hindurchgreift, wobei die Auskragung abdeckungsaußenseitig mit wenigstens einem Durchgang versehen ist, durch den, insbesondere jeweils, ein Verriegelungselement hindurchführbar ist.This object is achieved by a circuit breaker locking device with the features of claim 1, and in particular in that the means include that the base body has a projection on a side opposite the recess, with which the base body in the locked-out position from the inside of the cover by an in the cover formed, in particular rectangular, recess extends through to the outside of the cover, the projection on the outside of the cover being provided with at least one passage through which a locking element can be passed, in particular in each case.
Erfindungsgemäß greift also die Auskragung des Grundkörpers mit dem wenigstens einem Durchgang durch die Abdeckung nach außen hindurch, so dass der wenigstens eine Durchgang besonders gut zugänglich und ein Verriegelungselement besonders einfach hindurchführbar bzw. ein Vorhangschloss besonders einfach einhängbar ist. Dadurch, dass der wenigstens eine Durchgang von der Ausnehmung weg verlagert ist, besteht beim Einhängen eines Vorhangschlosses auch genügend räumliche Distanz zu dem jeweiligen Schutzschalter, so dass ein behinderungsfreies Einhängen möglich ist.According to the invention, the projection of the base body engages with the at least one passage through the cover to the outside, so that the at least one passage is particularly easily accessible and a locking element can be passed through particularly easily or a padlock can be attached particularly easily. Because the at least one passage is shifted away from the recess, there is also sufficient spatial distance to the respective circuit breaker when a padlock is hooked in so that it can be hooked in without hindrance.
Insbesondere kann die Auskragung besonders kompakt gehalten werden, so dass ein in einer Verwendungsstellung der Schutzschalter-Sperrvorrichtung horizontal ausgerichteter Durchgang besonders kurz gehalten werden kann, so dass auch bei einem horizontalen Durchgang ein Vorhangschloss nach unten hängend eingehängt werden kann, mit der Folge, dass auch für einen benachbarten Schutzschalter mehr Platz für eine eigene Schutzschalter-Sperrvorrichtung zur Verfügung steht. Sofern alternativ oder zusätzlich ein vertikal ausgerichteter Durchgang vorgesehen ist, muss in diesen ein Verriegelungselement, insbesondere ein Vorhangschloss, nicht umständlich eingefädelt werden.In particular, the projection can be kept particularly compact, so that in a position of use of the circuit breaker blocking device, it is horizontal aligned passage can be kept particularly short, so that even with a horizontal passage a padlock can be hung hanging down, with the result that more space is available for an adjacent circuit breaker for its own circuit breaker locking device. If, as an alternative or in addition, a vertically aligned passage is provided, a locking element, in particular a padlock, does not have to be laboriously threaded into it.
Ferner kann ein in einen vertikal ausgerichteten Durchgang eingehängtes Vorhangschloss im eingehängten Zustand zu beiden Seiten gedreht werden, um beispielsweise gezielt eine Gravur auf dem Schlosskörper des Vorhangschlosses lesen zu können, die z.B. einen Rückschluss auf den Besitzer des Vorhangschlosses, d.h. auf die Person, die den Ausschluss des Schutzschalters vorgenommen hat, erlaubt. Insbesondere kann ein derartig eingehängtes Vorhangschloss auch deshalb weggedreht werden, um Platz zu schaffen, wenn auf einen benachbarten Schutzschalter zugegriffen werden soll, insbesondere um auch dort eine Schutzschalter-Sperrvorrichtung zu setzen.Furthermore, a padlock hooked into a vertically oriented passage can be rotated on both sides in the hooked state, for example in order to be able to read an engraving on the lock body of the padlock in a targeted manner, for example, a conclusion about the owner of the padlock, ie the person who has the Exclusion of the circuit breaker has made, allowed. In particular, a padlock hung in this way can also be turned away in order to create space when an adjacent circuit breaker is to be accessed, in particular in order to also set a circuit breaker blocking device there.
Außerdem erschließt sich aufgrund der Anordnung des wenigstens einen Durchgangs außerhalb der Abdeckung für den Benutzer sofort, wo das Verriegelungselement hindurchgeführt werden muss. Insbesondere ist bei mehreren Durchgängen leicht erkennbar, dass mehrere Einhängevarianten für ein Vorhangschloss, beispielsweise horizontal oder vertikal, möglich sind. Die erfindungsgemäße Schutzschalter-Sperrvorrichtung ist daher auch besonders intuitiv bedienbar.In addition, because of the arrangement of the at least one passage outside the cover, it is immediately apparent to the user where the locking element has to be passed. In particular, when there are several passages, it is easy to see that several suspension variants for a padlock, for example horizontal or vertical, are possible. The circuit breaker blocking device according to the invention can therefore also be operated particularly intuitively.
Wie bereits vorstehend angedeutet ist, ist vorgesehen, dass in einer Verwendungsstellung der Schutzschalter-Sperrvorrichtung, in der der erste Abschnitt des Grundkörpers nach oben ausgerichtet ist, der wenigstens eine Durchgang horizontal, d.h. insbesondere von einer ersten lateralen Seite zu einer zweiten lateralen Seite der Auskragung, und/oder vertikal, d.h. insbesondere von einer Oberseite zu einer Unterseite der Auskragung, ausgerichtet ist. Ein horizontaler Durchgang bietet sich beispielsweise an, wenn ein Lesen einer Gravur auf dem Schlosskörper ohne Drehung des verwendeten Vorhangschlosses möglich sein soll. Sofern mehrere unmittelbar nebeneinander angeordnete Schutzschalter vorgesehen sind, die jeweils mit einer Schutzschalter-Sperrvorrichtung versehen werden sollen, bieten sich vertikale Durchgänge an, um ein behinderungsfreies Nebeneinandereinhängen der Vorhangschlösser zu ermöglichen.As already indicated above, it is provided that in a use position of the circuit breaker blocking device in which the first section of the base body is oriented upwards, the at least one passage horizontally, ie in particular from a first lateral side to a second lateral side of the projection , and / or vertically, ie in particular from one Top to a bottom of the projection, is aligned. A horizontal passage is useful, for example, if an engraving on the lock body should be able to be read without turning the padlock used. If several circuit breakers arranged directly next to one another are provided, each of which is to be provided with a circuit breaker blocking device, vertical passages are available to enable the padlocks to be hung next to one another without hindrance.
Bei einem Verriegelungselement kann es sich um ein Vorhangschloss, insbesondere einen Bügel eines Vorhangschlosses, handeln, wobei der Bügel starr oder flexibel, insbesondere als Kabelbügel, ausgebildet sein kann. Darüber hinaus kann ein Verriegelungselement auch als eine Kabelverriegelung mit einem Kabel ausgebildet sein, wobei insbesondere auch möglich ist, dass das eine Kabel durch die Durchgänge mehrerer Schutzschalter-Sperrvorrichtungen hindurchgeführt wird, so dass mit einer einzigen Kabelverriegelung gleichzeitig mehrere Schutzschalter-Sperrvorrichtungen gesichert werden können.A locking element can be a padlock, in particular a bracket of a padlock, wherein the bracket can be rigid or flexible, in particular as a cable bracket. In addition, a locking element can also be designed as a cable lock with a cable, in particular it is also possible that one cable is passed through the passages of several circuit breaker locking devices, so that several circuit breaker locking devices can be secured simultaneously with a single cable lock.
Der wenigstens eine Durchgang umfasst einen ersten Durchgang und einen zweiten Durchgang, so dass dem Benutzer mehrere Varianten zur Verfügung stehen, ein zur Festsetzung der Abdeckung an dem Grundkörper zu verwendendes Verriegelungselement relativ zu der Schutzschalter-Sperrvor-richtung auszurichten. Bei dem ersten Durchgang und dem zweiten Durchgang handelt es sich um einen horizontalen Durchgang und einen vertikalen Durchgang, wie sie vorstehend beschrieben sind, oder umgekehrt. Grundsätzlich ist es denkbar, dass mehr als zwei Durchgänge vorgesehen sind.The at least one passage comprises a first passage and a second passage, so that the user has several variants available for aligning a locking element to be used to fix the cover on the base body relative to the circuit breaker blocking device. The first passage and the second passage are a horizontal passage and a vertical passage as described above, or vice versa. In principle, it is conceivable that more than two passages are provided.
Im Sinne einer kompakten Ausbildung der Auskragung bzw. der Schutzschalter-Sperrvorrichtung ist es vorteilhaft, wenn sich der erste Durchgang und der zweite Durchgang schneiden, da in diesem Fall von den beiden Durchgängen möglichst wenig Platz beansprucht wird.In terms of a compact design of the projection or the circuit breaker blocking device, it is advantageous if the first passage and the second passage intersect, since in this case the two passages take up as little space as possible.
Insbesondere kann auch vorgesehen sein, dass der Durchmesser des ersten, beispielsweise horizontalen oder vertikalen Durchgangs kleiner ist als der Durchmesser des zweiten, beispielsweise vertikalen oder horizontalen Durchgangs. Durch das Vorsehen unterschiedlich großer Durchmesser für die beiden Durchgänge kann erreicht werden, dass für den Durchgang mit dem kleineren Durchmesser nur bestimmte Vorhangschloss-Typen - nämlich abhängig von der Dicke des Bügels des jeweiligen Vorhangschlosses - verwendet werden können. Der Durchdurchmesser des ersten Durchgangs und der Durchmesser des zweiten Durchgangs können jedoch auch identisch sein.In particular, it can also be provided that the diameter of the first, for example horizontal or vertical passage is smaller than the diameter of the second, for example vertical or horizontal passage. By providing diameters of different sizes for the two passages, it can be achieved that only certain padlock types - namely depending on the thickness of the shackle of the respective padlock - can be used for the passage with the smaller diameter. However, the diameter of the first passage and the diameter of the second passage can also be identical.
Darüber hinaus ist es bevorzugt, wenn eine an einem in der vorgenannten Verwendungsstellung der Schutzschalter-Sperrvorrichtung nach oben gerichteten Ende, an einer der Ausnehmung abgewandten Seite ausgebildete Kante der Auskragung eine Abschrägung aufweist, die sich bis in den vertikal ausgerichteten Durchgang erstreckt, derart, dass im Bereich der Abschrägung ein Abschnitt eines Öffnungsrands des vertikal ausgerichteten Durchgangs ausgebildet ist, der eine Ebene definiert, die gegen die Horizontale geneigt ist.In addition, it is preferred if an edge of the projection formed on an end facing upwards in the aforementioned position of use of the circuit breaker blocking device, on a side facing away from the recess, has a bevel that extends into the vertically oriented passage, such that In the region of the bevel, a section of an opening edge of the vertically oriented passage is formed which defines a plane which is inclined with respect to the horizontal.
Somit bildet der Öffnungsrand des vertikalen ausgerichteten Durchgangs im Bereich der Abschrägung eine insbesondere gerundete Aufnahme für den Bügel eines Vorhangschlosses. Hierdurch kann ein Vorhangschloss in definierter Lage in dem vertikal ausgerichteten Durchgang hängen, was insbesondere bei mehreren nebeneinander hängenden Vorhangschlössern von Vorteil ist. Dies gilt umso mehr, als ein Bügel eines Vorhangschlosses üblicherweise als Rundbügel ausgebildet ist und in einer gerundeten Aufnahme besonders lagestabil aufgenommen werden kann. Um ein seitliches Drehen eines vertikal eingehängten Vorhangschlosses zu erleichtern, kann das Vorhangschloss vor dem Drehen leicht angehoben werden.Thus, the opening edge of the vertically aligned passage in the area of the bevel forms a particularly rounded receptacle for the shackle of a padlock. As a result, a padlock can hang in a defined position in the vertically oriented passage, which is particularly advantageous when there are several padlocks hanging next to one another. This is all the more true as a bracket of a padlock is usually designed as a round bracket and can be received in a rounded receptacle in a particularly stable position. To make it easier to turn a vertically hung padlock sideways, the padlock can be lifted slightly before turning.
Darüber hinaus kann der erste Abschnitt des Grundkörpers einen Blockadeabschnitt aufweisen, der den Betätigungsabschnitt des Feststellelements gegen einen Zugang von ausnehmungsseitig bzw. einen ausnehmungsseitigen Zugang abschirmt. Der Zugang von den ansonsten offenen Seiten wird durch Verstellen der Abdeckung in ihre Aussperrstellung abgeschirmt. Grundsätzlich kann jedoch auch vorgesehen sein, dass die Abdeckung derart ausgebildet ist, dass sie in ihrer Aussperrstellung auch den ausnehmungsseitigen Zugang abschirmt.In addition, the first section of the base body can have a blocking section which shields the actuating section of the locking element from access from the recess side or from access from the recess side. Access from the otherwise open sides is shielded by moving the cover into its locked-out position. In principle, however, it can also be provided that the cover is designed in such a way that it also shields the access on the recess side in its locked-out position.
Die Abdeckung kann zumindest eine der der Ausnehmung gegenüberliegenden Seite des Grundkörpers zugeordnete Rückwand, eine dem ersten Abschnitt des Grundkörpers zugeordnete stirnseitige Wand und zwei einander gegenüberliegende Seitenwände umfassen, um in der Aussperrstellung den Betätigungsabschnitt des Feststellelements unzugänglich abzudecken. Hierdurch kann auf einfache Weise gewährleistet werden, dass in der Aussperrstellung der Abdeckung der Betätigungsabschnitt des Feststellelements von außen unzugänglich abgedeckt wird. Dabei ist es bevorzugt, wenn die Aussparung in der Rückwand der Abdeckung vorgesehen ist.The cover can comprise at least one rear wall assigned to the side of the base body opposite the recess, a front wall assigned to the first section of the base body and two opposite side walls in order to cover the actuating section of the locking element inaccessibly in the locked position. This makes it possible to ensure in a simple manner that, in the locked position of the cover, the actuating section of the locking element is covered inaccessibly from the outside. It is preferred here if the recess is provided in the rear wall of the cover.
Nach einer Ausführungsform der Erfindung umfasst die verstellbare Befestigung der Abdeckung an dem Grundkörper, dass die Abdeckung über eine Schwenkeinrichtung an dem Grundkörper, insbesondere an dem zweiten Abschnitt des Grundkörpers, zwischen der Freigabestellung und der Aussperrstellung schwenkbar befestigt ist. Eine derartige Befestigung kann besonders einfach realisiert werden, insbesondere im Zusammenhang mit dem Hindurchgreifen der Auskragung durch die in der Abdeckung ausgebildete Aussparung. Bevorzugt ist die Abdeckung über einen Schwenkbereich von wenigstens 45°, insbesondere wenigstens 90°, verschwenkbar.According to one embodiment of the invention, the adjustable fastening of the cover to the base body comprises that the cover is fastened to the base body, in particular to the second section of the base body, pivotably between the release position and the lockout position via a pivoting device. Such a fastening can be implemented in a particularly simple manner, in particular in connection with the protrusion reaching through the recess formed in the cover. The cover can preferably be pivoted over a pivoting range of at least 45 °, in particular at least 90 °.
Dabei kann die Schwenkeinrichtung umfassen, dass die Abdeckung in den zwei vorgenannten, einander gegenüberliegenden Seitenwänden jeweils eine Öffnung aufweist und der zweite Abschnitt des Grundkörpers an zwei einander gegenüberliegenden lateralen Seiten jeweils einen Zapfen aufweist, der in eine jeweilige der beiden Öffnungen eingreift, insbesondere eingerastet ist.In this case, the pivoting device can include that the cover has an opening in each of the two aforementioned, mutually opposite side walls and the second section of the base body on two mutually opposite lateral sides each has a pin which engages, in particular is latched, into a respective one of the two openings.
Um beim Zusammenbau der Schutzschalter-Sperrvorrichtung ein Aufschieben der Abdeckung auf den Grundkörper, insbesondere ein Einfahren des jeweiligen Zapfens bis zu der jeweiligen Öffnung, zu ermöglichen, kann die jeweilige Seitenwand der Abdeckung an ihrer Innenseite eine rinnenförmige Vertiefung aufweisen, die mit ihrem einen Ende in die jeweilige Öffnung mündet und sich mit ihrem anderen Ende bis zu einem Rand der jeweiligen Seitenwand erstreckt. Insbesondere verlaufen die beiden Vertiefungen parallel zueinander und auf gleicher Höhe. Die beiden Zapfen können jeweils eine Auflaufschräge für die Seitenwände der Abdeckung aufweisen, um ein Aufschieben der Abdeckung auf den Grundkörper zu erleichtern.In order to enable the cover to be slid onto the base body when assembling the circuit breaker blocking device, in particular to allow the respective pin to be retracted up to the respective opening, the respective side wall of the cover can have a channel-shaped recess on its inside, one end of which into the respective opening opens and extends with its other end to an edge of the respective side wall. In particular, the two depressions run parallel to one another and at the same height. The two pins can each have a run-up slope for the side walls of the cover in order to make it easier for the cover to be pushed onto the base body.
Die beiden Zapfen können z.B. jeweils zurückdrückbar ausgebildet sein. Wenn die beiden bei einem Aufschieben der Abdeckung zurückgedrückten Zapfen am Ende des Aufschiebevorgangs bis zu den Öffnungen eingefahren sind, können sie dort wieder ausfahren, um in die Öffnungen einzurasten. Gemäß einer anderen Ausbildung sind die beiden Zapfen jedoch unbeweglich ausgebildet, und die beiden Seitenwände der Abdeckung sind auseinanderdrückbar. Insbesondere im Zusammenhang mit dieser Ausbildung ist es bevorzugt, wenn zumindest die beiden Seitenwände der Abdeckung federelastisch ausgebildet sind, um bei einem Aufschieben der Abdeckung auf den Grundkörper ein Auseinanderdrücken der beiden Seitenwände zu ermöglichen.The two pins can, for example, each be designed so that they can be pushed back. When the two pins that are pushed back when the cover is pushed open have retracted as far as the openings at the end of the pushing-on process, they can extend there again in order to lock into the openings. According to another embodiment, however, the two pins are designed to be immovable, and the two side walls of the cover can be pushed apart. In particular in connection with this embodiment, it is preferred if at least the two side walls of the cover are designed to be resilient in order to enable the two side walls to be pushed apart when the cover is pushed onto the base body.
Vorzugsweise ist bzw. sind der Grundkörper und/oder die Abdeckung, insbesondere jeweils, als ein Spritzgussteil und/oder einstückig ausgebildet, so dass die Schutzschalter-Sperrvorrichtung bzw. deren Teile besonders einfach herstellbar ist bzw. sind. Darüber hinaus können mit einem Spritzgussverfahren ohne weiteres auch komplexe Formen hergestellt werden.Preferably, the base body and / or the cover, in particular in each case, are designed as an injection-molded part and / or in one piece, so that the circuit breaker blocking device or its parts can be manufactured particularly easily or are. In addition, complex shapes can easily be produced with an injection molding process.
