Abstract
Abstract A weatherproof terminal or junction box structure for a luminaire adapted for connection by a mast to a building or pole. The structure enables access to the terminal or junction box area for wiring and inspection without disassembly of the mounting of the luminaire to the mast and without the necessity of disassembling the luminaire itself. The mast telescopes within a channel receiver of the luminaire housing for mounting purposes. The mast is slotted at its entry end, the slot being encompassed within an access opening which may be covered by a wire way cover. Removal of the cover exposes the wiring for connection and inspection. With the cover in place, recessed within the receiver, the connection of mast to luminaire produces a weatherproof mounting. A second embodiment omits the need for the cover by normally setting the entry end slot rotated out of registration with the channel opening. Access to the slot may be had by rotating the luminaire about the axis of the channel receiver.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 words
A luminaire support structure for mounting a luminaire on a supporting mast having a tubular wall, comprising a mast receiver extending from said luminaire, said receiver comprising an open channel section with an open port at the end thereof, the base of said channel section sized to receive said mast wall in a tight-fitting, telescoping relation, said mast having a wire-receiving plug closing the bore of said mast at a location remote from the luminaire mounting, a longitudinal slot in the wall of said mast within the area telescoped within said receiver, means for clamping and holding said mast in said receiver, said clamping means allowing ready access to said mast slot through the open side of said channel, said mast and receiver cooperatively forming a terminal compartment to allow the making and inspecting of electrical connections within said mast through the opening formed by the alignment of said slot with the open side of the channel without disturbing the holding of the mast in said receiver, and means for covering the open side of said channel section to close access to said compartment through said slot whereby to weatherproof said compartment and its connection to the luminaire.
Claim 2
Dependent Claim
198 words
A luminaire support structure for mounting a luminaire on a supporting mast having a tubular wall, comprising a mast receiver extending from said luminaire, said receiver comprising an open channel section with an open port at the end thereof, the base of said channel section sized to receive said mast wall in a tight-fitting, telescoping relation, said mast having a wire-receiving plug closing the bore of said mast at a location remote from the luminaire mounting, a longitudinal slot in the wall of said mast within the area telescoped within said receiver, means for clamping and holding said mast in said receiver, said clamping means allowing ready access to said mast slot through the open side of said channel, said mast and receiver cooperatively forming a terminal compartment to allow the making and inspecting of electrical connections within said mast through the opening formed by the alignment of said slot with the open side of the channel without disturbing the holding of the mast in said receiver, and means for covering the open side of said channel section to close access to said compartment through said slot whereby to weatherproof said compartment and its connection to the luminaire.
Claim 3
Dependent Claim
49 words
A support structure as claimed in claim 1, wherein said clamping means comprises a support bar extending across the legs of the channel section and secured thereto, said covering means comprises a flat sheet member adapted to rest between the legs of said channel and to be secured thereto.
Claim 4
Dependent Claim
50 words
A support structure as claimed in claim 1, wherein said covering means include the wall of said mast adjacent said slot and the wall of said channel section, with one of said walls rotatable about an axis parallel to the length of said mast to cover or uncover said slot.
Claim 5
Dependent Claim
201 words
A luminaire support structure adapted to support a luminaire on a supporting mast by means of a mast receiver extending from said luminaire, in which said receiver comprises an open channel section with a U-shaped wall member having a port at the end of the channel section, the base of said channel section wall member sized to receive said mast in a tight-fitting telescoping relation, said mast comprising a tubular wall member, a longitudinal slot inset into the tubular wall member of said mast extending only within the area telescoped within said receiver, a clamping plate securable to said receiver for clamping said mast firmly in said receiver, said clamping plate allowing ready access to said mast slot through the open channel of the U-shaped wall member, said mast and receiver cooperatively forming a terminal compartment externally of the luminaire to allow the making and inspecting of electrical connections to said luminaire through the opening produced by the registry of the slot with said open channel, the receiver channel wall member positioned to cover the slot with one of said wall members rotated to close the opening to said compartment whereby to weatherproof said compartment and its connection to the luminaire.
Claim 6
Dependent Claim
201 words
A luminaire support structure adapted to support a luminaire on a supporting mast by means of a mast receiver extending from said luminaire, in which said receiver comprises an open channel section with a U-shaped wall member having a port at the end of the channel section, the base of said channel section wall member sized to receive said mast in a tight-fitting telescoping relation, said mast comprising a tubular wall member, a longitudinal slot inset into the tubular wall member of said mast extending only within the area telescoped within said receiver, a clamping plate securable to said receiver for clamping said mast firmly in said receiver, said clamping plate allowing ready access to said mast slot through the open channel of the U-shaped wall member, said mast and receiver cooperatively forming a terminal compartment externally of the luminaire to allow the making and inspecting of electrical connections to said luminaire through the opening produced by the registry of the slot with said open channel, the receiver channel wall member positioned to cover the slot with one of said wall members rotated to close the opening to said compartment whereby to weatherproof said compartment and its connection to the luminaire.
