Abstract

Abstract This is a recess ceiling dome particularly adapted to be installed in an existing building and specifically includes supporting members for ceiling joists that have been cut out to provide the opening to receive the dome which is adapted to permit a chandelier to be mounted therein while still providing adequate head room thereunder. This invention also consists in the method of installing the dome which includes initially cutting out an opening in the finished layer of the ceiling to expose the ceiling joists to be cut, supporting each of the joists to be cut from a portion of the frame structure of the existing building thereafter cutting through the joists around the edges of the opening and installing a chandelier receiving dome in the opening thus provided.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 85 words
The method of mounting a concave chandelier receiving dome in an existing ceiling comprising initially cutting in the finished ceiling layer an opening the size of the dome to be installed to expose the ceiling joists to be cut out above the opening area, supporting each of the joists to be cut from the frame structure of the building, cutting through said joists around the edges of said opening after supporting each of joists to be cut, and installing a concave dome in the opening.
Claim 2
Independent Claim 85 words
The method of mounting a concave chandelier receiving dome in an existing ceiling comprising initially cutting in the finished ceiling layer an opening the size of the dome to be installed to expose the ceiling joists to be cut out above the opening area, supporting each of the joists to be cut from the frame structure of the building, cutting through said joists around the edges of said opening after supporting each of joists to be cut, and installing a concave dome in the opening.
Claim 3
Dependent Claim 34 words
The method set forth in claim 1 and installing a pair of main support beams across the ceiling joists to be cut as well as selected joists which are not to be cut, and
Claim 4
Dependent Claim 20 words
attaching each of the joists to be cut to said beams to provide said support for the cut out joists.
Claim 5
Dependent Claim 20 words
attaching each of the joists to be cut to said beams to provide said support for the cut out joists.
Claim 6
Dependent Claim 17 words
The method set forth in claim 1 and installing a chandelier in the recess of the dome.
Claim 7
Dependent Claim 19 words
The method set forth in claim 3 and supporting the chandelier directly from the frame structure of the building.
Claim 8
Dependent Claim 125 words
A room ceiling structure in a building and including a finished ceiling a plurality of structural joist members supporting said ceiling and a concave dome mounted in said ceiling in a building for suspending a chandelier type hanging fixture and comprising an integrally formed pre-fabricated concave open bottom dome unit adapted to be installed in a ceiling opening of a size substantially greater than the space between more than two joist members and formed in the ceiling of a building, and having a peripheral flange integrally formed around the lower edge thereof and extending radially outwardly from said lower edge, means supporting the dome unit from the ceiling structure of the building with the flange thereof attached to said ceiling and engaging the surface thereof.
Claim 9
Dependent Claim 125 words
A room ceiling structure in a building and including a finished ceiling a plurality of structural joist members supporting said ceiling and a concave dome mounted in said ceiling in a building for suspending a chandelier type hanging fixture and comprising an integrally formed pre-fabricated concave open bottom dome unit adapted to be installed in a ceiling opening of a size substantially greater than the space between more than two joist members and formed in the ceiling of a building, and having a peripheral flange integrally formed around the lower edge thereof and extending radially outwardly from said lower edge, means supporting the dome unit from the ceiling structure of the building with the flange thereof attached to said ceiling and engaging the surface thereof.
Claim 10
Dependent Claim 52 words
The structure set forth in claim 5 and supporting means comprising a pair of beams extending across in overlying relation the cut joist members forming said opening and pre-determined continuous joist members disposed beyond said opening, and means connecting said beams to the underlying joist members to support the cut joist members.
Claim 11
Dependent Claim 47 words
The structure set forth in claim 5 and said supporting means comprising a plurality of substantially vertically extending tying elements connected at their lower ends to the cut joist members forming said opening and at their upper ends to the rafters of the roof of the building.
Claim 12
Dependent Claim 38 words
The structure set forth in claim 6 and a plurality of spaced substantially vertically extending tying members attached to said supporting beams at their lower ends and to the roof rafters of the building at their upper ends.
Claim 13
