ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a holder for electric lights, and more particularly to a holder for holding large glass dome lights suspended from high ceilings.
2. Description of Prior Art
In most glass dome holders and supports, the glass dome and holder are connected to a high bay unit above an auditorium, gymnasium or other type of large room using glass dome lights. The dome and its support are fixed to the high bay unit. The electrician then installs the wiring necessary to run power from the bay unit to a socket and bulb assembly. The socket and bulb assembly is then fixed, so that the bulb is positioned within the glass dome.
The electrician's work is long and cumbersome because he must work around the large glass dome and its support structure when he installs the wiring, and the socket and bulb assembly. Additionally, the electrician must install the wiring high above the ground, and may decide that the location of the bulb inside the dome is not given the appropriate lighting. The electrician must then undo the wiring or adjust the wiring, so that the bulb is in the appropriate location. This trial and error method continues for every light in the room.
The present invention eliminates this problem by providing a large glass dome holder that can be installed quickly and easily after the wiring of the socket and bulb assembly has been put into place. The invention also allows for fixed adjustments of the location of the bulb within the glass dome.
SUMMARY OF THE INVENTION
In accordance with a preferred embodiment of the present invention, a glass dome holder is provided having a lower ring assembly for supporting the bottom flange of a glass dome, and an upper ring assembly for supporting the neck of the glass dome. The holder includes a plurality of elongated spoke members, each having a hooked end and a looped end. The bottom flange of the glass dome is disposed on the lower ring assembly. The upper ring assembly is located on the neck of the glass dome. The hooked end of the elongated wire members are each placed over the upper ring assembly. The body of the wire members run from neck of the glass dome to the bottom flange of the glass dome. The looped end of the wire members are each fixedly attached to the lower ring assembly by conventional means. The dome holder surrounds the glass dome.
A pair of J-bracket assemblies are fixed to the upper ring assembly and are positioned at opposite sides of the ring assembly. The J-bracket assemblies each include a lower portion that conforms to the circumference of the ring assembly, and an upper portion having right and left rod holding members. The middle of the upper portion is adapted to receive a rod holding member from a J-bracket. The J-bracket has a first end having a rod holding member and a second end that is shaped like a J or a hook. The rod holding member of the J-bracket is placed between right and left holding members of one of the J-bracket assemblies. A conventional rod or bolt is placed through the three rod holding members and locked in place. This fixes the J-bracket to the ring assembly.
A pair of connecting brackets are mounted to opposite ends of a customer supplied U-bracket that is mounted to a high bay unit. The connecting bracket is mounted via connection holes on top of the connecting bracket. The bracket may include a plurality of guide hole pairs and slots for holding a socket and bracket assembly in an adjustably fixed position. The connecting bracket includes a lower end with a right and left rod holder. A conventional rod or bolt extends through the right and left rod holder such that the middle portion of the rod or bolt is exposed between the right and left rod holder. The entire glass dome and holder structure can be easily mounted to the ceiling, after the electrical wiring has been completed, by placing the J or hooked end of the J-bracket over the exposed portion of the rod or bolt through the connecting bracket. The rod or bolt can then be tightened to cause the right and left rod holder to lock in the J or hooked end of the J-bracket. The J-bracket on the other side of the upper ring assembly is then locked into place causing the entire glass dome structure to be connected to the high bay unit, and to be suspended high above the ground or floor. In other words the connecting brackets, the J brackets and the J bracket assemblies are holding means for connecting the glass dome holder to the high bay unit.
An object of this invention is to provide a glass dome holder that can fix a glass dome to a support structure after the electrical wiring of the bulb socket has been completed.
Another object of this invention is to provide a glass dome holder that can be easily fixed and removed from the support structure.
An additional object of this invention is to provide a glass dome holder that provides easy adjustment of the placement of the bulb within the glass dome.
Another object of this invention is to provide an adjustment of the position of the bulb within the glass dome that can be performed before or after the placement of the glass dome.
A further object of this invention is to provide a glass dome holder that is low in cost, easy to manufacture, easy to assemble and easy to adjust.
