Electrical enclosure apparatus
View Patent ↗An openable cover for an enclosure configured to house a switching device, the switching device being configured with an operating member operable between a first position and a second position. The openable cover comprises a moveable member operable in response to movement of the operating member. The movable member is configured to prevent opening of the cover member when the operating member is in the first position, and configured to prevent closing of the cover member when the operating member is in the second position.
1. An enclosure for a switching device, the switching device being configured with an operating member operable between a first ON position and a second OFF position, the enclosure comprising:
a housing configured to support the switching device, said housing comprising an interlock formation:
a housing cover operable between a first closed position and a second open position, said housing cover configured with an aperture therethough;
an interlock member moveably connected to said cover, said interlock member defining an aperture therethrough sized to operatively receive the switching device operating member, the interlock member operative to move in response to movement of switching device operating member;
said interlock member configured to engage said housing interlock formation to prevent movement of said housing cover from said first closed position to said second open position when the switching device operating member is in the first ON position; and wherein
said interlock member aperture and said cover aperture are configured to cooperate to permit the switching device operating member to operably protrude from said housing when said housing cover is in the first closed position.
2. The enclosure of claim 1 , wherein said interlock member is further configured to prevent movement of said housing cover from said second open position to said first closed, position when the switch device operating member is in the second OFF position.
3. The enclosure of claim 1 , wherein said interlock member is movably connected to said housing cover by fasteners.
4. The enclosure of claim 3 , wherein said fasteners are shouldered rivets.
5. The enclosure of claim 1 , wherein said interlock formation comprises a tab.
6. The enclosure of claim 1 , wherein said interlock formation comprises an aperture.
7. An openable cover for a housing for a switching device, the switching device being configured with an operating member operable between a first ON position and a second OFF position, the openable cover comprising:
a first aperture defined therethrough; and
an interlock member moveably coupled to said cover, defining a second aperture therethrough sized to operatively receive the switching device operating member, said interlock member operative to move in response to movement of the switching device operating member;
said interlock member configured to engage a formation in the housing to prevent opening, of said cover when the switching device operating member is in the first ON position; wherein
said cover first aperture and said interlock member second aperture are configured to cooperate to permit the switching device operating member to operably protrude from said housing when said housing cover is in the first closed position.
8. The cover of claim 7 , wherein said interlock member is further configured to prevent closing of said cover when the switch device operating member is in the second OFF position.
9. The enclosure of claim 7 , wherein said interlock member is movably connected to said housing cover by fasteners.
10. The enclosure of claim 9 , wherein said fasteners are shouldered rivets.
11. The enclosure of claim 7 , wherein said interlock formation comprises a tab.
12. The enclosure of claim 7 , wherein said interlock formation comprises an aperture.
