Abstract
A plastic floor box assembly for use with electrical raceways installed in concrete floors, having a plastic box, an activation ring, a cover plate for retaining an electrical outlet, and an outlet cover securable to the cover plate. The activation ring is secured within the open top of the floor box by a plurality of retaining clips, having barbs extending outwardly and upwardly therefrom. The barbs allow easy insertion of the activation ring into the box, while preventing withdrawal. In a second embodiment designed for use in tile floors, a pair of support clips are also provided on the activation ring to prevent over-insertion of the ring into the box.
Claims11
A floor box assembly for use with electrical conduits and related wiring, comprising:
- a box having an open top bounded by a peripheral edge having an inner side surface, with at least one hub formed in a wall thereof for operatively attaching one of said electrical conduits, whereby said wiring is received within said box, said box being disposable in a concrete floor;
- an activation ring receivable within said open top of said box;
- at least one retaining clip fastenable to said activation ring, said retaining clip having gripping means associated therewith for operatively engaging at least a portion of said inner side surface of said peripheral edge, said gripping means including at least one barb extending laterally outwardly and upwardly from said retaining clip, said barb being operative to engage said inner side surface of said peripheral edge of said open top thereby resisting removal of said activation ring from said box and securing said activation ring within said box upon insertion of said ring through said open top;
- a cover plate securable to said activation ring, having mounting means associated therewith for retaining an outlet operatively connectable to said wiring;
- and
- an outlet cover, securable to said cover plate.
A floor box assembly for use with electrical conduits and related wiring, comprising:
- a box having an open top bounded by a peripheral edge having an inner side surface, with at least one hub formed in a wall thereof for operatively attaching one of said electrical conduits, whereby said wiring is received within said box, said box being disposable in a concrete floor;
- an activation ring receivable within said open top of said box;
- at least one retaining clip fastenable to said activation ring, said retaining clip having gripping means associated therewith for operatively engaging at least a portion of said inner side surface of said peripheral edge, thereby securing said activation ring within said box upon insertion of said ring through said open top;
- and
- at least one support clip engaging an underside portion of said activation ring, having an upper lip extending laterally therefrom for operatively engaging said peripheral edge of said box and at least a portion of the floor adjacent said edge upon installation of said activation ring, said support clip being operative to prevent over-insertion of said activation ring within said box.
An activation ring assembly for use with a plastic electric floor box having an open top end, comprising:
- a ring member comprising an annular wall adapted to fit within said open top end of said box;
- at least one retaining clip secured to said wall of said ring member, said clip having gripping means associated therewith for engaging said top end of said box upon insertion of said ring member therein, said gripping means including at least one barb extending outwardly and upwardly from said retaining clip, said barb being operative to engage said open top, thereby resisting removal of said ring member from said box and retaining said ring member within said box.
A floor box assembly for use with electrical conduits and related wiring, comprising:
- a box having an open top bounded by a peripheral edge having an inner side surface, with at least one hub formed in a wall thereof for operatively attaching one of said electrical conduits, whereby said wiring is received within said box, said box being disposable in a concrete floor;
- an activation ring receivable within said open top of said box;
- at least one retaining clip fastenable to said activation ring, said retaining clip having gripping means associated therewith for operatively engaging at least a portion of said inner side surface of said peripheral edge, said gripping means including a plurality of barbs extending from said retaining clip, said barbs being operative to engage said inner side surface of said peripheral edge of said open top, thereby resisting removal of said activation ring from said box and securing said activation ring within said box upon insertion of said ring through said open top;
- a cover plate securable to said activation ring, having mounting means associated therewith for retaining an outlet operatively connectable to said wiring;
- and
- an outlet cover, securable to said cover plate.
An activation ring assembly for use with a plastic electric floor box having an open top end, comprising:
- a ring member comprising an annular wall adapted to fit within said open top end of said box;
- and
- at least one retaining clip secured to said wall of said ring member, said retaining clip having gripping means associated therewith for engaging said top end of said box upon insertion of said ring member therein, said gripping means comprises a plurality of barbs extending from said retaining clip, said barbs being operative to engage said open top, thereby resisting removal of said ring member from said box and retaining said ring member within said box.
