Thereby, the ballast 5 can be fit easily and fitting workability of the ballast 5 can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floodlight mount for mounting a floodlight on a column, and more particularly to a floodlight mount having a ballast mount for mounting a ballast.

[0002]

2. Description of the Related Art FIG. 10 shows a conventional floodlight mount (first conventional example). This floodlight mount is used for mounting a floodlight 2 on a concrete pillar 1 when illuminating a ground or the like. The projector mounting base 3 and the ballast mounting base 4 are provided.

The floodlight mounting base 3 is a pair of rod-shaped members which are arranged substantially parallel to each other in a substantially vertical direction on the concrete pillar 1 which is a pillar erected on the ground and sandwiching the concrete pillar 1 therebetween. The mounting base body 3a and the floodlight mounting base 3 are installed between the mounting base body 3a and in the vicinity of the substantially central portion of the mounting base body 3a with the concrete pillar 1 interposed therebetween.
Mounting band 3b for mounting on the mounting base 3
It is configured to have a projector mounting plate 3c which is installed between a and for mounting the projector 2.

The ballast mount 4 is used to mount the ballast 5 on the concrete pillar 1, and is a flexible band 4a which can be wound around and fixed to the concrete pillar 1.
Is configured.

Therefore, when mounting the projector 2 and the ballast 5, after mounting the projector mounting base 3 of the projector base near the upper end of the concrete pillar 1 which is the mounting position for the concrete pillar 1, the projector mounting plate in the air is installed. The light projector 2 is attached to 3c, and then the ballast 5 is attached to the concrete pillar 1 in the vicinity of the light emitter mount 3 by the free band 4a that constitutes the ballast mount 4, and the light projector 2 and the power source are connected. The electric wiring was done and the construction was done.

FIG. 11 and FIG. 12 show a second conventional example of a floodlight mount, in which the point different from the first conventional example is a ballast mount 4, and the other is the first conventional example. Is configured similarly to.

The ballast mount 4 is suspended from the mount body 3a of the floodlight mount 3 to attach the ballast 5 to the concrete column 1.
It is used to mount on the projector mount 3
A pair of horizontal pieces 4b arranged substantially parallel to the mounting base body 3a and spaced apart from each other, vertical pieces 4c vertically fixed to the horizontal pieces 4b at both ends of the horizontal piece 4b, and the vertical pieces It is configured to have a plurality of ballast mounting plates 4d extending between the pieces 4c in parallel with the vertical pieces 4c, that is, in the vertical direction with respect to the concrete pillar 1. Also, the ballast mounting plate 4d
Is provided with an upper leg mounting hole 4e near the upper end for mounting an upper leg (not shown) of the stabilizer 5 with bolts and nuts, and a lower leg (not shown) of the stabilizer 5 is provided below the hole 4e. Is similarly provided with a lower leg mounting hole 4f for mounting with a bolt and a nut, and the lower leg mounting hole 4f is long in the vertical direction for mounting the ballast 5 of various sizes, for example, about 200 mm to 500 mm in total length. It is said to be a long hole.

In the floodlight mount thus constructed, when the floodlight 2 and the ballast 5 are mounted on the concrete pillar 1 which is a column, the floodlight mount is assembled on the ground, and the floodlight 2 and the ballast 5 are mounted to make the electrical connection. After wiring, they were lifted up to the mounting position of the concrete pillar 1 to be mounted, thereby reducing the work at high places and improving workability and safety.

[0009]

However, in the floodlight mount shown in the first conventional example configured as described above, since the stabilizer 5 is directly attached to the concrete column 1 which is the support column by the adjustable band 4a, It is necessary to perform the work at a high place above the concrete pillar 1 which is the mounting position of the ballast 5, and as a result, materials such as the ballast 5 which is a heavy load weighing several kilograms to 20 kilograms,
There is a problem in that work is performed by lifting the work up to the mounting position one by one, and the mounting work takes time and the workability is poor, and it is unfavorable for safety because there are many work at high places.

Further, in the floodlight mount shown in the second conventional example, it is possible to reduce the work at high places and increase the work on the ground, but the ballast 5 to the ballast mounting plate 4d is required.
Since the upper and lower legs of the ballast 5 are attached by bolts and nuts, it takes time to attach them, and there is a problem that workability is still poor.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a floodlight mount having excellent workability in mounting a ballast.

[0012]

In order to solve the above-mentioned problems, the present invention solves the above problems by mounting a projector 3 on which a projector 2 is mounted and to which a projector 2 is mounted, and a stabilizer 5 mounted on the projector mounting base 3. And a ballast mount 4 on which the ballast mount 4 is mounted, wherein the ballast mount 4 is
A ballast mounting plate 4d having a hanger portion 4g for hooking the upper leg 5a of the ballast 5 near the upper end, and the ballast mounting plate 4d and the lower leg 5b of the ballast 5 are simultaneously clamped, and
It is characterized in that it is configured to have a slide metal fitting 4h that is vertically slidable.

[0013]

As described above, according to the present invention, the projector mount 3 which is supported by the column 1 and to which the projector 2 is attached, and the ballast mount 4 which is attached to the projector mount 3 and to which the ballast 5 is attached are mounted. In the projector mount having the ballast mounting plate 4d, the ballast mounting base 4 has a hanger portion 4g for catching the upper leg 5a of the ballast 5 near the upper end.
Since the ballast mounting plate 4d and the lower leg 5b of the ballast 5 are sandwiched at the same time, and the slide metal fitting 4h is slidable in the vertical direction, the ballast 5 is mounted on the ballast mounting base. 4 is mounted on the ground, the hanger portion 4 near the upper end of the ballast mounting plate 4d is mounted.
The upper leg 5a of the ballast 5 is hung on the g to bring the ballast 5 into a suspended state, the lower leg 5b is brought into contact with the ballast mounting plate 4d, and the slide metal fitting 4h is slid upward from below to make a slide metal fitting. By fixing the lower leg 5b together with the ballast mounting plate 4d by 4h, the ballast 5 can be easily attached to the ballast mounting base 4 on the ground, and the projector mount is lifted to the mounting position of the column 1 to support the column. If it is attached to No. 1, the construction is completed and the workability of attaching the ballast 5 is improved.
