Wiring duct unit

Claim 2

An elongated wiring duct-like enclosure for surface mounting of electrical wiring to a support structure, comprising a base member having a first sidewall and a second sidewall joined by a bottom wall and said sidewalls having substantially aligned outer ends, a cover integrally connected to the outer end of said first sidewall, said cover having an outer edge, said base member including its sidewalls and bottom wall being formed of plastic, the outer edge of said cover adapted to mate with the outer end of said second sidewall, said cover and said second sidewall having a releasable connection means for releasably securing of said cover to said second sidewall, and means for securing said base member to a support structure with said cover located in spaced relation to said support structure for movement of the cover between a closed position and an open position, a first locking wall secured to said first sidewall and projecting toward said second sidewall in spaced relation to said bottom wall, a second locking wall secured to said second sidewall and projecting partially inwardly toward said first sidewall in substantial alignment with said first locking wall, said first and second locking walls being aligned and defining a locking slot for receiving a locking tab for interconnection of similar abutting enclosures.

Claim 3

The elongated wiring duct-like enclosure of claim 1 wherein said base member is an extruded plastic member of a substantially rectangular cross-section, said cover is integrally molded with said first sidewall and connected thereto by an integral hinge portion permitting manual pivoting of the cover relative to said sidewalls.

Claim 4

The elongated wiring duct-like enclosure of claim 2 wherein said hinge portion and cover and base member are an integral duodurometer extruded assembly and wherein said hinge portion is formed of a flexible plastic, and said cover and said base member are formed of a rigid plastic.

Claim 5

The elongated wiring duct-like enclosure of claim 1 wherein said releasable connection means includes a latching wall secured to said second sidewall and defining a latching recess extending along the length of said second sidewall, said cover having a latching projection of a cross section substantially complementing said latching recess and located to mate with said latching recess with the cover pivoted downwardly into abutting engagement with said second sidewall.

Claim 6

The elongated wiring duct-like enclosure of claim 1 including a second base member corresponding in structure to said first-named base member and having an opening in the lower portion of one of its spaced sidewalls, said first-named base member having an end abutting said second base member at said opening, and a locking tab extending between said first and second base members and into at least one of said locking slots.

Claim 7

The elongated wiring duct-like enclosure of claim 1 wherein a second base member corresponding in structure to said first-named base member is joined at one end to an end of the first-named base member with said ends abutting, said ends of said base members being formed with mating angled surfaces to define an angled conduit, and a locking tab extends between said abutting ends and into locking engagement with said locking slots in said base members.

Claim 8

The elongated wiring duct-like enclosure of claim 1 wherein said enclosure is formed of an extruded plastic.

Claim 9

The elongated wiring duct-like enclosure of claim 1 wherein said base member is rectangular in cross-section and said first and second spaced sidewalls and said bottom wall are each a flat wall of the same thickness, said cover being of the same thickness as said bottom wall and connected to said first sidewall by a thin integral portion defining a hinge.

Claim 10

A wiring enclosure for enclosing wires extended along the surfaces of a housing structure, comprising an extruded plastic conduit member of a substantially rectangular cross-section, said conduit member having a substantially rigid U-shaped base including a flat mounting wall and first and second outwardly extending parallel sidewalls integrally formed with said mounting wall, a cover integrally molded with said first sidewall and connected thereto by a thin integral hinge portion having a thickness significantly less than the thickness of said cover and said first sidewall, said thin hinge portion permitting manual pivoting of the cover relative to said sidewalls, a latching wall secured to said second sidewall and defining a latching recess extending along the length of said second sidewall, said cover having a latching projection of a cross-section substantially complementing said latching recess and located to mate with said latching recess with the cover pivoted downwardly into abutting engagement with said second sidewall, said latching wall being spaced from the mounting wall of said base, a locking wall secured to the interior of said first sidewall and projecting partially inwardly into said U-shaped base in outwardly spaced relation to the mounting wall, said latching wall and said locking wall defining a locking slot for receiving a locking tab for interconnection of similar abutting enclosures.

Claim 11

A wiring enclosure for enclosing wires extended along the surfaces of a housing structure, comprising an extruded plastic conduit member of a substantially rectangular cross-section, said conduit member having a substantially rigid U-shaped base including a flat mounting wall and first and second outwardly extending parallel sidewalls integrally formed with said mounting wall, a cover integrally molded with said first sidewall and connected thereto by a thin integral hinge portion having a thickness significantly less than the thickness of said cover and said first sidewall, said thin hinge portion permitting manual pivoting of the cover relative to said sidewalls, a latching wall secured to said second sidewall and defining a latching recess extending along the length of said second sidewall, said cover having a latching projection of a cross-section substantially complementing said latching recess and located to mate with said latching recess with the cover pivoted downwardly into abutting engagement with said second sidewall, said latching wall being spaced from the mounting wall of said base, a locking wall secured to the interior of said first sidewall and projecting partially inwardly into said U-shaped base in outwardly spaced relation to the mounting wall, said latching wall and said locking wall defining a locking slot for receiving a locking tab for interconnection of similar abutting enclosures.

Claim 12

The wiring enclosure of claim 9 wherein said latching recess is formed with a slightly narrow entrance opening adjacent the outer edge of said second sidewall, said latching projection on said cover having an outer portion slightly larger than said entrance opening to provide a releasable friction latch of said cover to said second sidewall.

Claim 13

The wiring enclosure of claim 9 wherein said enclosure is formed of polyvinyl chloride plastic.
