Bei
Wie vorstehend aufgeführt weist die Stromunterbrechungsvorrichtung 100 nach einem praktischen Ausführungsbeispiel der vorliegenden Erfindung die folgenden Vorteile auf:
- 1. Das gleitend bewegliche Teil 133 weist grundsätzlich eine U-Form auf, wobei
die U-förmige Öffnung 1330 und dieEingangsöffnung 1323 gegenüber befindlich sind. Auf diese Weisewird das Nockenradteil 1314 aus der zweiten Richtung D2 durch dieEingangsöffnung 1323 und dieU-förmige Öffnung 1330 zwischen die ersteSeitenplatte 1332 und diezweite Seitenplatte 1334 des gleitend beweglichen Teiles 133 gesteckt, treibt das gleitend bewegliche Teil 133 zur Bewegung an und bewirkt die Verriegelung desHandgriffes 120 durch den erstenBolzen 1335. Aus diesem Grund bestehen relativ geringe Anforderungen an die Präzision der Abstimmung zwischendem Nockenradteil 1314 und dem gleitend beweglichen Teil 133 - insbesondere in der zweiten Richtung D2 und der dritten Richtung D3 -, was die Herstellungskosten senkt und die Montage erleichtert. - 2. Die Anordnung
von erstem Bolzen 1335 und zweitem Bolzen 1336 an der ersten Seitenplatte 1332 weicht von der Anordnungvon erstem Bolzen 1335 und zweitem Bolzen 1336 an der zweiten Seitenplatte 1334 ab, so dass verhindert wird, dass der Verwender infolge von Unachtsamkeit bei der Montage die zweite Seitenplatte 1334 - also die Verriegelungsseite für die Verriegelung in geschlossener Position - zur Verriegelung des in geöffneterPosition befindlichen Handgriffes 120 verwendet, beziehungsweise die erste Seitenplatte 1332 - also die Verriegelungsseite für die Verriegelung in geöffneter Position - zur Verriegelung des in geschlossenerPosition befindlichen Handgriffes 120 verwendet. Somit kann die Sicherheit des Bedienungspersonals bei geöffnetem, geschlossenem oder in Wartung befindlichem Zustand gewährleistet werden. - 3. Dadurch dass die erste
Seitenplatte 1332 des gleitend beweglichen Teiles 133 als Verriegelungsseite für die Verriegelung in geöffneter Position verwendet wird und diezweite Seitenplatte 1334 als Verriegelungsseite für die Verriegelung in geschlossener Position verwendet wird, kann wahlweise die ersteSeitenplatte 1332/zweite Seitenplatte 1334 zur Verriegelung desHandgriffes 120 in geöffneter/geschlossener Position verwendet werden.
- 1. The sliding
member 133 has basically a U-shape with theU-shaped opening 1330 and theentrance opening 1323 facing each other. In this way, thecam gear member 1314 is inserted from the second direction D2 through theinput port 1323 and theU-shaped opening 1330 between thefirst side plate 1332 and thesecond side plate 1334 of the slidablymovable member 133, drives theslidable member 133 to move and causes the locking of thehandle 120 by thefirst bolt 1335. For this reason, there are relatively low demands on the precision of the coordination between theNockenradteil 1314 and the sliding part 133 - in particular in the second direction D2 and the third direction D3 - Lowers production costs and facilitates assembly. - 2. The arrangement of the
first bolt 1335 and thesecond bolt 1336 on thefirst side plate 1332 deviates from the arrangement of thefirst bolt 1335 and thesecond bolt 1336 on thesecond side plate 1334, thus preventing the user from being careless when assembling the second side plate 1334 - so the locking side for the lock in the closed position - used to lock thehandle 120 in the open position, or the first side plate 1332 - so the locking side for the lock in the open position - used to lock thehandle 120 in the closed position. Thus, the safety of the operators can be ensured in the open, closed or in maintenance befindlichem state. - 3. By using the
first side plate 1332 of the slidingmovable member 133 as the locking side for the lock in the open position and thesecond side plate 1334 as the locking side for the lock in the closed position, thefirst side plate 1332 /second side plate 1334 may optionally be used Locking thehandle 120 are used in the open / closed position.
