Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a support pole device used to support any object.

For example, outdoor lighting equipment is sometimes supported at the tip of a pole, and in this case, when the direction of light projection of the lighting equipment is variable, it is required that the angle at which the lighting equipment is attached to the pole is adjustable. In order to support a lighting fixture on a pole so that the angle can be adjusted in this way, conventionally a U-shaped frame is fixed to the top end of the pole, and a similarly U-shaped frame is fixed to the rear of the lighting fixture. By interlocking the two frames, the lighting fixture was supported on the upper end of the pole, and one frame was rotatable relative to the other frame.

However, with such a support structure, a frame must be fixed to each of the lighting equipment and the pole, making the structure complicated. The most important thing is that this support involves the inconvenience of having to continue supporting the lighting fixture in some way until both frames are connected. When the weight of a lighting fixture is large, supporting it is extremely cumbersome.

The purpose of this invention is to facilitate support on a pole and to simplify the configuration for this purpose.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a pole, and a recess 2 is formed in the periphery of the upper end of the pole. Further, a pair of nuts 3 are fixed to the peripheral wall near the upper end by welding or the like. 4 is the support metal fittings,
At least the bottom surface is open, and on the top surface 5,
The object to be supported, ie, the lower surface 7 of the lighting fixture 6, is placed and fixed by bolts 8A and nuts 8B. Top surface 5. A hole 9.10 is formed in the lower surface 7, through which a cable (not shown) from the luminaire 6 is guided into the pole 1. An arm 11 is arranged in the support fitting 4 so as to cross the inside thereof. The arm 11 is fixed to the side wall 4A of the support fitting 4 by welding or the like. Further, arc-shaped elongated holes 12 are formed in the opposite side walls 4A. A bolt 13 is inserted into the support fitting 4 through this elongated hole 12. The tip thereof is screwed into a nut 3. 14 is a spring washer. 15 is a washer.

As mentioned above, the mounting bracket 4 is fixed to the lighting fixture 6 in advance with bolts 8A and nuts 8B.
To support the lighting fixture 6 on the pole 1,
The pole 1 is installed so that the upper end thereof is covered with the mounting bracket 4, that is, the upper end of the pole 1 is inserted into the mounting bracket 4. During this process, the arm 11 is dropped into the recess 2. As a result, the mounting bracket 4 is placed on the upper end of the pole 1. The position of the nut 3 is adjusted in advance so that it faces the elongated hole 12 in this placed state. In this state, the mounting bracket 4 can be easily rotated about the arm 11 in the direction A (FIG. 1). Therefore, the bolt 13 is screwed into the nut 3 through the elongated hole 12 at any rotational position. The mounting bracket 4 is fixed to the pole 1 by this screwing.

Pole 1 of mounting bracket 4 once installed
To change the angle with respect to the angle, loosen the bolt 13 to release the fixation with the mounting bracket 4, and then tighten the bolt 13 again at the required angle position. Alternatively, the bolt 13 may be removed. In this case, the arm 11 is in the recess 2, so the mounting bracket 4
will not fall off pole 1. In this state, the mounting bracket 4 is attached to the upper end of the pole 1 and the arm 1
It can be easily rotated around 1. 16 is a scale plate indicating this angle. Note that in place of the elongated hole 12, a plurality of holes may be provided independently.

As detailed above, according to this invention, the mounting bracket is placed on the top of the pole by placing it over the top of the pole and dropping the arm into the recess. There is no need to continue supporting the object with the mounting bracket until it is fixed to the object, which makes the supporting work that much easier.Furthermore, the mounting bracket only needs to be fixed to the object, and the pole does not have a frame. Since mounting metal fittings are not required, the structure for support is simplified, which is advantageous.

In the illustrated embodiment, a lighting fixture is supported by a pole, but the supported object is not limited to a lighting fixture; for example, a speaker. It can be used to support electrical equipment such as ultrasonic vehicle detector sensors and other arbitrary items. Further, in the configuration shown in the figures, instead of installing the nut 3, a threaded portion may be formed directly on the pole 1, and the bolt 13 may be screwed into this.
