[5 7] ABSTRACT A mounting assembly for a bulbholder formed by a C- shaped yoke member having spaced end arms, and a pair of spring support sub-assemblies resiliently supporting opposite ends of the bulbholder from the end arms. Each spring sub-assembly is adjustable relative to the yoke end arm so that the bulbholder may be aimed upwardly or downwardly to project the light as desired.
11 Claims, 4 Drawing Figures I BULIIIIOLDER MOUNTING ASSEMBLY BACKGROUND OF THE INVENTION This invention relates generally to bulbholder support devices and more particularly to a bulbholder mounting assembly in which the bulbholder and the lamp contained therein are protected from vibration and shock damage, while at the same time the most efficient and maximum light projection from the lamp is obtained.
When larger wattage lamps, such as 1,000 watt multi vapor lamps, and their bulbholders are mounted in a conventional rigid fashion on a light pole, frequently they become damaged by vibration and shock conditions to which they are subjected, especially in heavily industrialized areas. While the bulb-holder must be adequately supported in a stable condition from a light pole, nevertheless it is desirable that the bulbholder have some degree of resiliency sufficient to protect the lamp from vibration and shock damage.
In addition, it is highly beneficial and desirable to have a lamp which may be adjusted either upwardly or downwardly so that the light emitted from the lamp may be projected or aimed as desired. There are no known bulbholder mounting assemblies which provide the total combination of these advantages and the invention described herein was developed with those desirable characteristics in mind to overcome the problems associated with prior known constructions.
SUMMARY OF THE INVENTION Accordingly, the primary object of this invention resides in the provision of a novel, bulbholder mounting assembly which provides a stable support for a lamp and its bulbholder and minimizes the amount of vibration and shock to which the lamp is subjected.
Another object of the invention resides in the provision of a novel bulbholder mounting assembly formed by a main C-shaped, yoke support member having spaced end arms and a pair of spring mounted subassemblies supporting opposite ends of a bulb holder between the end arms of the yoke member. The spring assemblies provide a resilient support connection between the bulb holder and the yoke member and thereby protect the lamp itself from vibration and shock damage which might be caused by forces applied to the main yoke member and the light pole on which it may be supported.
A further object of the invention resides in the provision of a novel bulbholder mounting assembly as discussed in the previous objects, wherein each of the spring support sub-assemblies is adjustable relative the yoke member so that the bulbholder may be adjusted through substantially 360 and the light from the lamp may be aimed or projected upwardly or downwardly as desired.
Still other objects and advantages of the invention will become apparent from reading the following detailed description of a preferred embodiment of the invention, in which like elements are indicated by like numerals. However, it is to be understood that the detailed description of the preferred embodiment is for illustrative purposes only, and that the scope of the invention is determined only by the appended claims.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a fragmentary front elevation view of the novel bulbholder mounting assembly, with the bulbholder itself positioned to project the light downwardly in a vertical direction;
FIG. 2 is a top plan view taken generally along line 2-2 of FIG. l, but with the bulbholder turned approximately 180 from its position in FIG. I to display the lamp therein, the light from which would then be projected vertically upwardly;
FIG. 3 is a fragmentary elevation view taken generally along line I'M-3 of FIG. I and illustrating the construction of the spring support sub-assemblies; and
FIG. 4 is a fragmentary side elevation view taken generally along line 4- of FIG. 2 illustrating the manner in which the mounting assembly would be attached to a conventional light pole.
DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, a lamp M), such as a L000 watt multi vapor lamp, is mounted in conventional fashion within a commercially available bulbholder 12 having opposed side extensions I4 and 16, one of which, e.g., extension I6, is formed as a conventional electrical socket to receive the socket end of the lamp 110 in conventional fashion. The outer tip end of the lamp may be additionally grasped and supported by a wire form support 17 within the bulbholder itself. The bulbholder 12 will be supported in suitable fashion, such as, for example, from a vertical light pole 64 by a mounting assembly 20 which constitutes the subject matter of this invention.
Spring assembly 3@ includes a channel plate member 34 the rear of which abuts against a small plate piece 36 that is welded to the end of the yoke arm 28. Plate 34 is fastened to arm 28 by way ofa weld nut 38 which is welded within the channel member and a bolt 39 lel to the plate member 34. A pair of springs 5h extend between one end of plate $6 and the end flanges 4d of plate all), while a second pair of springs 52 extend be-- tween the other end of plate 46 and the end flanges 4d of plate 42.
As shown in FIG. d, the yoke 22 is readily connected to a light pole, or a similar mounting member by way of a bracket assembly 5d which includes a U-shaped section $6 which extends around the center yoke section 2d, a flat abutment plate $8 welded to section 56 at the rear of center section 24 and a bolt 60 which threads through aligned openings in section 56, center section 24, and plate 58, and functions to properly position yoke 22 relative to plate 58. The flat mounting plate 58 provides sufficient mounting surface so that it may readily be attached to a corresponding bracket assembly 62 mounted on a light pole 64.
The described preferred embodiment of the invention provides the objects and advantages which were initially set forth above. For example, the C-shaped yoke member is sufficiently rigid to mount the bulbholder and the lamp supported therein in an elevated vertical position on a light pole, while the spring subassemblies 30 and 32 provide sufficient resiliency in the system to protect the bulbholder and lamp itself from damage due to shock and/or vibration which may be transmitted to the light pole and/or the yoke member 22.
ln addition, because the plates 34 of spring assemblies 30 and 32 are readily adjustable relative to the yoke arms 26 and 28 by loosening bolts 39, the bulb holder 12 is adjustable through essentially 360 so that the light from lamp may be projected or aimed upwardly or downwardly as desired. Thus, simply by loosening bolts 39, plates 34 may be rotated relative to arms 26 and 28, thus causing proper aiming or orientation of the bulb holder 12 and lamp 10.
The described bulb holder and mounting assembly provides a complete, lightweight floodlight unit having very good light projection qualities and providing maximum protection of the light itself, thereby affording reliable, efficient and long-term service life, and reducing operating costs. The bulbholder and its mounting assembly are well suited for extreme rough service, since the yoke and the resilient spring assemblies effectively shield the lamp itself from the vibration and shock forces.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
