Claim 6

A fitting as defined in claim 1 and further characterized by: said first member having a substantially planar, rectangular body portion; said groove forming means formed on said first member and comprising a pair of depending, offset rib portions extending transversely along opposite, parallel side edge portions of said rectangular body portion, each said rib having a slot longitudinally cut therealong and opening laterally outwardly of said body portion said grooves each having a sidewall forming said load bearing surface and disposed parallel to opposite ones of a pair of downwardly converging planes disposed obliquely to a plane containing said planar body portion and equally slanted downwardly therefrom.

Claim 7

A fitting as defined in claim 5 and further characterized by: said second member comprising an upwardly opening channel-shaped member having a substantially planar medial section and a spaced pair of substantially upstanding sidewalls extending transversely along opposite side edge portions of said medial section; said tongue forming means formed on said second member and comprising a pair of flanges formed along upper terminal edge portions of said upstanding sidewalls and extending obliquely thereof and inwardly of said channel-shape member, said pair of flanges disposed along opposite ones of a pair of planes converging inwardly of said channel-shaped member and disposed parallel to said planes containing said load bearing surfaces.

Claim 8

A fitting as defined in claim 1 and further characterized by: said first member having a substantially planar body portion, and said means for attaching said first member to the conduit line comprising a junction box; and fastening means attaching said planer body to said junction box.

Claim 9

A fitting as defined in claim 7 and further characterized by said planar body portion of said first member having a substantially centrally disposed cutout formed therethrough for receiving electrical leads extending from the junction box.

Claim 10

A fitting as defined in claim 1 and further characterized by: said means for attaching said first member to the conduit line comprising a hub portion disposed on said first member and having an internally threaded throughbore formed therein for receiving a complementary threaded nipple depending from the conduit line.

Claim 11

A fitting as defined in claim 1 and further characterized by: said second member comprising a channel-shaped member having a planar medial section and a spaced pair of upstanding sidewalls disposed at opposite side edge portions of said medial section; said means for attaching said second member to the pendent light fixture comprising said medial section having an aperture formed therethrough, and a hub fixedly received in said aperture and having an internally threaded throughbore formed therein for receiving an upstanding, complementary threaded nipple attached to the light fixture.

Claim 12

A fitting as defined in claim 10 and further characterized by: said hub having a radially extending flange formed thereon and overlying said medial section; a resilient gasket interposed between said radial flange and said medial portion for absorbing vibrations; and fastening means attaching said radial flange to said medial section and clamping said gasket therebetween.

Claim 13

A fitting as defined in claim 10 and further characterized by said hub having means forming a swivel joint.

Claim 14

A fitting as defined in claim 1 and further characterized by: said means for attaching said second member to the pendent light fixture comprising means forming a hook member fixedly attached to said second member and including a shank portion depending from said second member, and an upwardly opening hook portion having an upstanding tip; and an electrical power receptacle attached to said second member; said tip of said hook member being disposed relative to said electrical power receptacle so that substantially no space remains between said tip and an electrical plug whenever the latter is inserted in said receptacle.

Claim 15

A fitting for attaching pendent light fixtures to a conduit line, comprising: first and second interconnected members, means for attaching said members respectively to a conduit line and a pendent light fixture, said members forming a wiring compartment for receiving lead wires to electrically connect the light fixture; means on one of said members forming at least one elongated, laterally opening groove having an open end; means on another of said members forming a tongue portion slidably inserted into said groove; and cover means selectively attached to one of said members and disposed to close said groove open end for restraining relative movement between said members when in an attached position and to close said wiring compartment for concealing lead wires disposed therewithin.

Claim 16

A fitting for attaching pendent light fixtures to a conduit line, comprising: first and second interconnected members, means for attaching said members respectively to a conduit line and a pendent light fixture, said members forming a wiring compartment for receiving lead wires to electrically connect the light fixture; means on one of said members forming at least one elongated, laterally opening groove having an open end; means on another of said members forming a tongue portion slidably inserted into said groove; and cover means selectively attached to one of said members and disposed to close said groove open end for restraining relative movement between said members when in an attached position and to close said wiring compartment for concealing lead wires disposed therewithin.

Claim 17

A fitting as defined in claim 14, one of said members being attachable to a conduit line and forming an opening from said wiring compartment to an interior of the conduit line; and another of said members being attachable to a pendent light fixture and forming an opening into said wiring compartment for receiving lead wires from the light fixture.

Claim 18

A fitting as defined in claim 14, one of said members comprising a channel shaped member having a medial portion and a pair of spaced-apart, sidewalls extending toward the other of said members and cooperating with said other member to form said wiring compartment between said members.

Claim 19

A fitting for use in attaching a high bay pendent light fixture to a conduit line comprising: first and second parts together with one another forming said fitting; one of said parts having coupling means for attaching said one part to a conduit line; the other of said parts having coupling means for attaching said other of said parts to a pendent light fixture; said first and second parts having mating tongue and groove portions formed therebetween so that the pendent light fixture with one of said parts connected thereto may be slidably connected in assembly with the conduit line having the other part connected thereto.

Claim 20

A fitting for use in attaching a high bay pendent light fixture to a conduit line comprising: first and second parts together with one another forming said fitting; one of said parts having coupling means for attaching said one part to a conduit line; the other of said parts having coupling means for attaching said other of said parts to a pendent light fixture; said first and second parts having mating tongue and groove portions formed therebetween so that the pendent light fixture with one of said parts connected thereto may be slidably connected in assembly with the conduit line having the other part connected thereto.
