Claim 2

Mounting device for a luminaire adapted to be mounted on an elongated support comprising, in combination, a support member, a pair of spaced bracket members secured to and projecting from said support member, a base member spaced from said support member, a pair of brace members secured to said base member and projecting therefrom toward said support member in juxtaposed relation respectively to said bracket members, and clamping means adjustably secured to said base member defining a passage between said brace members for receiving the elongated support along the axis of said passage and for clamping the same therein, said bracket members respectively being adjustably secured to said brace members for adjustment relative thereto about an axis transverse said first mentioned axis.

Claim 3

A device as defined in claim 1, said brace members and said bracket members comprising plate-like members, said bracket members being arranged in overlapping relation with the respective brace members.

Claim 4

Mounting device for a luminaire adapted to be mounted on an elongated support comprising, in combination, a support member, a pair of spaced bracket members secured to and projecting from said support member, a base member spaced from said support member, a pair of brace members secured to said base member and projecting therefrom toward said support member in juxtaposed relation respectively to said bracket members, and clamping means adjustably secured to said base member defining a passage between said brace members for receiving the elongated support along the axis of said passage and for clamping the same therein, said bracket members respectively being adjustably secured to said brace members for adjustment relative thereto about an axis transverse said first mentioned axis, said brace members and said bracket members comprising plate-like members, said bracket members being arranged in overlapping relation with the respective brace members, first connecting means securing each bracket member to the adjacent brace member along said transverse axis, each bracket member having a slot and being secured to the adjacent brace member by second fastening means passing through said slot, whereby said bracket member is adjustable to selected positions relative to said brace member about said first connecting means.

Claim 5

Mounting device for a luminaire adapted to be mounted on an elongated support comprising, in combination, a support member, a pair of spaced bracket members secured to and projecting from said support member, a base member spaced from said support member, a pair of brace members secured to said base member and projecting therefrom toward said support member in juxtaposed relation respectively to said bracket members, and clamping means adjustably secured to said base member defining a passage between said brace members for receiving the elongated support along the axis of said passage and for clamping the same therein, said bracket members respectively being adjustably secured to said brace members for adjustment relative thereto about an axis transverse said first mentioned axis, said brace members and said bracket members comprising plate-like members, said bracket members being arranged in overlapping relation with the respective brace members, first connecting means securing each bracket member to the adjacent brace member along said transverse axis, each bracket member having a slot and being secured to the adjacent brace member by second fastening means passing through said slot, whereby said bracket member is adjustable to selected positions relative to said brace member about said first connecting means.

Claim 6

A device as defined in claim 3, said first and second connecting means being in vertically spaced alignment.

Claim 7

A device as defined in claim 2, said brace members being substantially L-shaped with leg portions thereof resting on said base member and having end edges facing each other in spaced relation on opposite sides of said first mentioned axis, whereby the support member may be clamped against said end edges of said brace members for holding the mounting device in tight engagement with the support member.

Claim 8

A device as defined in claim 2, said clamping means comprising a pair of U-bolts arranged spaced on said base member along said first mentioned axis.

Claim 9

A luminaire comprising, in combination, a support member, a first housing covering one side of said support member, a second housing covering the opposite side of said support member, and slipfitter means secured to said support member for mounting the luminaire on an elongated support, said slipfitter means comprising a pair of spaced bracket members secured to and projecting from said support member, a base member spaced from said support member, a pair of brace members secured to said base member and projecting therefrom toward said support member in juxtaposed relation respectively to said bracket members, and clamping means adjustably secured to said base member defining a passage between said brace members for receiving the elongated support along the axis of said passage and for clamping the same therein, said bracket members respectively being adjustably secured to said brace members for adjustment relative thereto about an axis transverse said first mentioned axis.

Claim 10

A luminaire comprising, in combination, a support member, a first housing covering one side of said support member, a second housing covering the opposite side of said support member, and slipfitter means secured to said support member for mounting the luminaire on an elongated support, said slipfitter means comprising a pair of spaced bracket members secured to and projecting from said support member, a base member spaced from said support member, a pair of brace members secured to said base member and projecting therefrom toward said support member in juxtaposed relation respectively to said bracket members, and clamping means adjustably secured to said base member defining a passage between said brace members for receiving the elongated support along the axis of said passage and for clamping the same therein, said bracket members respectively being adjustably secured to said brace members for adjustment relative thereto about an axis transverse said first mentioned axis.

Claim 11

A luminaire as defined in claim 7, said slipfitter means extending into and being enclosed by said second housing, said luminaire including an optical assembly secured to said second housing.

Claim 12

A luminaire as defined in claim 8, said transverse axis extending in a direction normal to said first mentioned axis.
