Abstract
A bell end adapter arrangement facilitates assembly of conduit sections through which associated electrical wiring and/or cables are routed. The arrangement includes a bell end adapter assembly having an outer bell end adapter, and an inner sleeve portion fixed within the outer adapter. The adapter assembly particularly facilitates routing of wiring from a conduit section positioned within a concrete slab or like flooring element, with the adapter assembly configured to be inserted into the slab and joined to the conduit section disposed within the slab. The adapter assembly has a outwardly flared, bell-shaped open mouth which is configured to receive a second conduit section through which wiring form the first conduit section is routed.
Claims12
A bell end adapter arrangement, comprising:
- a concrete slab;
- a first section of electrical conduit positioned in the concrete slab;
- a second section of electrical conduit;
- and
- a bell end adapter assembly having a generally tubular configuration, including a first end defining a first opening for disposition in said first section of electrical conduit, and a second end defining a second opening for receiving said second section of electrical conduit, said adapter assembly extending above said concrete slab with the second end thereof being accessible to facilitate connection of said second conduit section thereto,
- said bell end adapter assembly comprising an outer bell end adapter, and an inner sleeve member extending below said outer bell end adapter, said inner sleeve member having an upper portion disposed within said bell end adapter, and a lower portion extending below said bell end adapter and extending into said first section of electrical conduit.
A bell end adapter arrangement in accordance with claim 4, wherein
- said outer surface of said inner sleeve member has an inwardly tapered configuration of about 3 degrees.
A bell end adapter arrangement, comprising:
- a concrete slab;
- a first section of electrical conduit positioned in the concrete slab;
- a second section of electrical conduit;
- and
- a bell end adapter assembly having a generally tubular configuration, including a first end defining a first opening for disposition in said first section of electrical conduit, and a second end defining a second opening for receiving said second section of electrical conduit, said adapter assembly extending above said concrete slab with the second end thereof being accessible to facilitate connection of said second section of electrical conduit thereto,
- said bell end adapter assembly comprising an outer bell end adapter, and an inner sleeve member extending within and below said bell end adapter, said inner sleeve member having an upper portion disposed within said bell end adapter, and a lower portion extending below said bell end adapter and extending into said first section of electrical conduit,
- said inner sleeve member including an outer surface at said first end of said bell adapter assembly having an inwardly tapered configuration, said first conduit section including an inside surface having an outwardly tapered configuration for receiving said outer surface of said inner sleeve member,
- wherein an inside diameter of said inner sleeve member is the same as an inside diameter of said first conduit section.
