A ceiling connector assembly for mounting an article includes a ceiling connector configured to present an article-mounting end region below a downward facing ceiling surface, a canopy structure for locating on the mounting end region and configured to cover, at least in part, the mounting end region in a covering position, the canopy structure and the mounting end region each respectively including at least one first mounting structure and at least one second mounting structure, wherein when the first and second mounting structures are configured to enable the canopy structure to be removably mounted on the mounting end region in the covering position.
1. A ceiling connector assembly for mounting an article, comprising a ceiling connector configured to present an article-mounting end region below a downward facing ceiling surface, a canopy structure for locating on the mounting end region and configured to cover, at least in part, the mounting end region in a covering position, the mounting end region and the canopy structure each respectively including at least one mounting post structure and at least one mounting sleeve structure, wherein the mounting post structure and the mounting sleeve structure are configured to enable the canopy structure to be removably mounted on the mounting end region in the covering position, the mounting-post structure and the mounting sleeve structure including respective outer and inner threaded portions, wherein the inner threaded portion on the mounting sleeve structure includes an inner passage having a first threaded section with a first diameter to threadably engage a corresponding outer threaded portion on the mounting post structure, and wherein the inner passage has a second section with a second diameter which is dimensioned to receive a stem structure therein.
2. The assembly of claim 1 , wherein the stem structure includes a stem inner passage with a stem inner threaded portion to threadably engage the mounting post structure.
3. A ceiling connector assembly for mounting an article, comprising a ceiling connector with at least one mounting post structure configured to present an article-mounting end region below a downward facing ceiling surface, a canopy structure for locating on the mounting end region and configured to cover, at least in part, the mounting end region in a covering position, the canopy structure including at least one mounting sleeve structure, wherein the at least one mounting post structure and the at least one mounting sleeve structure are configured to enable the canopy structure to be removably mounted on the mounting end region in the covering position, the at least one mounting post structure and the at least one mounting sleeve structure including respective outer and inner threaded portions, wherein the inner threaded portion includes an inner passage having a first threaded section with a first diameter to threadably engage the corresponding outer threaded portion on the at least one mounting post structure, wherein the at least one mounting sleeve structure and/or the at least one mounting post structure are/is configured for the mounting post structure to project beyond the mounting sleeve structure when the canopy structure is in the first mounted position.
4. The assembly of claim 3 , wherein the at least one mounting sleeve structure and the at least one mounting post structure are configured so that the inner passage is annular shaped to receive the stem structure.
5. The assembly of claim 4 , wherein the stem structure is configured to extend axially along the inner passage.
6. The assembly of claim 5 , wherein the stem inner passage is in communication with a cavity adjacent the ceiling connector to form a passageway for wiring therebetween to power the article to be mounted on the stem structure.
7. A canopy structure for locating on a mounting end region of a ceiling connector for mounting an article below a downward facing ceiling surface, comprising at least one mounting structure configured to enable the canopy structure to be removably mounted on the mounting end region in the covering position, wherein the mounting end region and the mounting structure include respective outer and inner threaded portions, and the inner threaded portion on the mounting structure includes an inner passage having a first threaded section with a first diameter to threadably engage a corresponding outer threaded portion on the mounting end region, wherein the inner passage has a second section with a second diameter which is dimensioned to receive a stem structure therein.
8. The assembly of claim 7 , wherein the stem structure includes a stem inner passage with a stem inner threaded portion to threadably engage the mounting end region.
9. The assembly as defined in claim 7 , wherein the mounting structure and/or the mounting end region are/is configured for the mounting end region to project beyond the mounting structure when the canopy structure is in a first mounted position.
10. The assembly of claim 9 , wherein the mounting structure and mounting end region are configured so that the inner passage is annular shaped to receive the stem structure.
11. The assembly of claim 10 , wherein the stem structure is configured to extend axially along the inner passage.
12. The assembly of claim 11 , wherein the stem inner passage is in communication with a cavity adjacent the ceiling connector to form a passageway for wiring therebetween to power the article to be mounted on the stem structure.
