Architectural light and adjustment means therefor

Claim 2

In a lighting fixture of the type which is to be supported from spaced hanger bars, the improvement comprising, in combination: a mounting frame defining an open center portion and having diametrically located support means thereon adapted for securement to said hanger bars to support the mounting frame therefrom, a circularly cylindrical housing of smaller crosssectional area than the area of the open center portion defined by the mounting frame, the housing having means for carrying a light bulb therein, connecting means for supporting the housing on the mounting frame at selected positions relative to the mounting frame, said connecting means including a plurality of circumferentially spaced resilient members mounted on said frame that provide a plurality of inwardly directed protuberances; the housing having locating means comprising a plurality of annular recesses axially spaced along its outer surface for cooperating witH said connecting means to permit manual selective axial positioning and rotative adjustment of the housing with respect to the mounting frame by releasable cooperative engagement of the plurality of protuberances with an annular recess.

Claim 3

A construction as in claim 1 further including means within said annular recesses for engaging said protuberances to restrain the housing from rotating relative to the connecting means.

Claim 4

In a lighting fixture of the type which is to be supported from spaced hanger bars, the improvement comprising, in combination: a mounting frame defining an open center portion and having diametrically located support means thereon adapted for securement to said hanger bars to support the mounting frame therefrom, a housing of smaller cross-sectional area than the area of the open center portion defined by the mounting frame, the housing having means for carrying a light bulb therein, connecting means for supporting the housing on the mounting frame; the housing having means axially spaced along its outer surface for cooperating with said connecting means to enable selective axial positioning of the housing with respect to the mounting frame; the support means comprising spring members each with a hanger bar-receiving aperture therethrough and biased to normally grip a hanger bar, but affording selective movement of the spring members against said bias to a position permitting relative sliding movement between the spring members and the hanger bars.

Claim 5

In a lighting fixture of the type which is to be supported from spaced hanger bars, the improvement comprising, in combination: a mounting frame defining an open center portion and having diametrically located support means thereon adapted for securement to said hanger bars to support the mounting frame therefrom, a housing of smaller cross-sectional area than the area of the open center portion defined by the mounting frame, the housing having means for carrying a light bulb therein, connecting means for supporting the housing on the mounting frame; the housing having means axially spaced along its outer surface for cooperating with said connecting means to enable selective axial positioning of the housing with respect to the mounting frame; the support means comprising spring members each with a hanger bar-receiving aperture therethrough and biased to normally grip a hanger bar, but affording selective movement of the spring members against said bias to a position permitting relative sliding movement between the spring members and the hanger bars.

Claim 6

A construction as in claim 3 wherein each of said support means comprises a generally V-shaped metal spring member with each side of the V defining a slot therein for receiving a hanger bar adapted to extend through both slots of said support means, whereby manual movement of the sides of the V toward each other against the normal bias of the spring member will align the slots for unobstructed sliding entry therethrough of a hanger bar, and release of the sides of the V when the hanger bar is in the slots will enable the walls defining the slots to frictionally engage the hanger bar to provide a restraining force against relative sliding movement between the generally V-shaped spring member and the hanger bar.

Claim 7

A construction as in claim 3 wherein said housing is circularly cylindrical and said mounting frame is annular, said mounting frame having an inside diameter that is greater than the outside diameter of the cylindrical housing whereby said housing can move axially through said mounting frame.

Claim 8

A construction as in claim 3 wherein said connecting means and said support means comprise metal spring members, and vertical posts carried by the mounting frame for securing the metal spring members to the mounting frame.

Claim 9

A construction as in claim 4 wherein the slots are generally L-shaped to receive substantially flat bars with their surfaces lying in either a horizontal plane or a vertical plane or to receive bars having an L-shaped cross-sectional configuration.

Claim 10

A construction as in claim 5 further including cylindrical skirt means for enclosing the portion of the housing extending below the mounting frame, and means for supporting said skirt means from the housing.

Claim 11

In a lighting fixture of the type which is to be supported from spaced hanger bars, the improvement comprising, in combination, a mounting frame defining an open center portion and having diametrically located support means thereon adapted for securement to hanger bars to support the mounting frame therefrom, a housing for carrying a light bulb, means for connecting said mounting frame to the housing, each of said support means including at least one spring member with a hanger bar-receiving aperture therethrough and biased to frictionally grip the hanger bar extending therethrough, but affording selective movement of said spring member against said bias to a position that permits relative sliding movement between the spring member and the hanger bar, each of the support means including a genErally V-shaped metal spring member with each side of the V defining a slot therein for receiving a hanger bar adapted to extend through the two slots of the two sides of the hanger bar-carrying means, whereby manual flexing of the sides of the V toward each other against the normal bias of the spring member will align the slots to permit sliding movement of the spring member relative to the hanger bar and release of the sides of the V with the hanger bar in the slots will enable the sides of the spring member to grip the hanger bar to prevent such sliding movement.

Claim 12

In a lighting fixture of the type which is to be supported from spaced hanger bars, the improvement comprising, in combination, a mounting frame defining an open center portion and having diametrically located support means thereon adapted for securement to hanger bars to support the mounting frame therefrom, a housing for carrying a light bulb, means for connecting said mounting frame to the housing, each of said support means including at least one spring member with a hanger bar-receiving aperture therethrough and biased to frictionally grip the hanger bar extending therethrough, but affording selective movement of said spring member against said bias to a position that permits relative sliding movement between the spring member and the hanger bar, each of the support means including a genErally V-shaped metal spring member with each side of the V defining a slot therein for receiving a hanger bar adapted to extend through the two slots of the two sides of the hanger bar-carrying means, whereby manual flexing of the sides of the V toward each other against the normal bias of the spring member will align the slots to permit sliding movement of the spring member relative to the hanger bar and release of the sides of the V with the hanger bar in the slots will enable the sides of the spring member to grip the hanger bar to prevent such sliding movement.

Claim 13

A construction as described in claim 9, wherein the slots are generally L-shaped to receive substantially flat bars with their surfaces lying in either a horizontal plane or a vertical plane or to receive bars having an L-shaped cross-sectional configuration.
