Abstract
Abstract A ceiling ring for mounting speakers in a ceiling. The ceiling ring is especially adapted for mounting a speaker from the bottom side of the ceiling after the ceiling has been constructed. The ceiling ring comprises a plaster ring inserted through the top of a hole in the ceiling and a closing plate which nests from below the ceiling within the plaster ring after the ceiling has been finished. The closing plate has an inwardly extending flange defining a central opening and opposite cutout portions which receive the speaker which is provided with a circular grill extending beyond the bottom edges of the speaker and which has a pair of flat sides which fit through the cutout opening in the rim-like flange of the closing plate when the speaker is turned perpendicularly on its side. The speaker, after it has been inserted, is righted and rests upon the flange by gravity. The closing plate can be clamped to the plaster ring by a workman who has availability through the central opening of the plaster ring to fasten connecting bolts extending from the plaster ring through slots in the closing plate.

Claim 2
Dependent Claim
117 words
A ceiling ring for mounting a speaker in a ceiling as it is being constructed and a speaker, said ceiling ring comprising a plaster ring having a shallow tubular configuration and a retaining element extending outwardly from a top end of the ring, said ring being adapted to be inserted from the top of a ceiling wall through a hole therein, a closing plate having a shallow tubular configuration receivable within said plaster ring through a bottom end of the ring, said closing plate being provided with an outwardly extending rim-like element adapted to cover the bottom portion of the finished ceiling around said hole, said closing plate being further provided with means for supporting the speaker.
Claim 3
Dependent Claim
109 words
The ceiling ring of claim 1 in which the means for supporting the speaker in the closing plate comprises an inwardly extending rim-like flange defining a central opening and having opposite side portions of a greater opening diameter than the remainder of said flange, said speaker having a flat generally circular rigid speaker grill extending beyond the bottom of the speaker, said grill having a width in at least one direction greater than the diameter of the central opening in the closing plate in order that the speaker may be turned perpendicular-ly to the horizon and inserted through the opening and mounted in the righted position upon said flange.
Claim 4
Dependent Claim
110 words
The ceiling ring of claim 1 in which the means for supporting the speaker in the closing plate comprises an inwardly extending rim-like flange defining a central opening and having opposite side portions of a greater opening diameter than the remainder of said flange, said speaker having a flat generally circular rigid speaker grill extending beyond the bottom of the speaker cone, said grill having a pair of flat opposite sides with the distance therebetween being less than central opening of said rim-like flange in order that the speaker may be turned perpendicularly to the horizon and inserted through the opening and mounted in the righted position upon said flange.
Claim 5
Dependent Claim
43 words
The ceiling ring of claim 1 in which the plaster ring is provided with inwardly extending elongated elements which are receivable within openings in the closing plate and means cooperating with said elongated elements for clamping the closing plate to the plaster ring.
Claim 6
Dependent Claim
43 words
The ceiling ring of claim 2 in which the plaster ring is provided with inwardly extending elongated elements which are receivable within openings in the closing plate and means cooperating with said elongated elements for clamping the closing plate to the plaster ring.
Claim 7
Dependent Claim
67 words
The ceiling ring of claim 4 in which the elongated elements on the plaster ring comprise bolts fitting through vertically elongated openings in the closing plate and nuts are provided to bear against the interior of the closing plate and clamp it to the plaster ring, said closing plate being adjustable along its axis toward and away from the plaster ring to accommodate ceilings of varying thicknesses.
Claim 8
Dependent Claim
