Abstract

PROBLEM TO BE SOLVED: To easily change and adjust to height of a lamp after the installation of an outdoor lamp by mounting a plurality of pole elements having male and female engagement portions on an utility pole, and mounting a stopper means for determining the engagement amount on the male and female engagement portions. SOLUTION: A telescopic pole 3 comprises three pole elements 3a, 3b, 3c comprising male and female engagement portions 4, 5, and the male and female engagement portions 4, 5 respectively comprise stopper means for determining an engagement amount L. The pole elements 3a, 3b, 3c are hollow, an upper side thereof is thinner than a lower side thereof, so that a lower end portion of the upper side serves as the male engagement portion 5 and an upper end portion of the lower side serves as the female engagement portion 4. As the stopper means 6, for example, the holes are formed on the opposite side faces of the female engagement portion 4, the through holes are formed on the male engagement portion 5 in multi-stage, and a headed pin is inserted into one through hole from the hole to be projected from the opposite hole.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an outdoor light used for lighting a street, a plaza, a park, or the like.

[0002]

2. Description of the Related Art Outside lights were built for crime prevention in the old days, but due to the development of automobile traffic, they are always lit for traffic safety on main streets and highways. In addition, outdoor lights are often built in shopping streets and parks to beautify the streets and parks. In general, the height of the pole of the external light is determined in advance at the time of design, and a lamp is generally installed at the upper end thereof.

[0003]

However, once the outdoor light is installed in a shopping street or a park, it is easy to change the height of the lamp in accordance with the installation site or the surrounding environment. There was a problem that can not be changed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has been made to solve the above-mentioned problems. The exterior light illumination can be easily changed and adjusted in accordance with the installation site and surrounding environment even after the exterior light is installed. It is intended to provide structure.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a pole provided with a lamp at its upper end, a plurality of pole elements having male and female fitting portions, The fitting portion is provided with a stopper means for determining the fitting amount, and the pole is configured to be adjustable in expansion and contraction by adjusting the fitting amount of each male and female fitting portion.

According to a second aspect of the present invention, the pole element is formed such that an upper stage side is made thinner than a lower stage side, so that an external light pole can be provided with a sense of stability. .

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an installation state of a lamp outside the present application, and FIGS. 2A and 2B are enlarged perspective views showing stopper means.

The external lamp body 1 comprises a lamp 2 and an extendable pole 3 having the lamp 2 at its upper end. Light 2
Fluorescent lamps, mercury lamps, sodium lamps that pass light even in fog, and the like are used.

The extendable pole 3 has a plurality of male and female fitting portions 4 and 5 (three in this embodiment).
And the male and female fitting portions 4, 5 are provided with stopper means 6 for determining the fitting amount L.

Each of the pole elements 3a, 3b, 3c
Is the longest at the bottom. That is, the male and female fitting portion 4,
This is to prevent the stopper means 6 for determining the fitting amount L of 5 from reaching even the height of an adult so as not to be tampered with during normal times.

Each of the pole elements 3a, 3b, 3c
Is formed hollow (the uppermost stage does not have to be hollow), the upper stage is made thinner than the lower stage, the lower end of the upper stage is formed as a male fitting portion 5, and the upper end of the lower stage is formed. Can be fitted as the female fitting portion 4. Although not shown, each of the pole elements 3a, 3b, and 3c may have a common thickness, and the male and female fitting portions 4, 5 may be provided at each end.
Is the same as long as

Although the structure of the stopper means 6 is not particularly limited, FIGS. 2 (a) and 2 (b) show typical examples of this embodiment. First, FIG. 2A shows the lower female fitting portion 4.
Are provided on the opposing side surfaces, and through holes 9a, 9b,... Are provided in the upper male side fitting portion 5 in multiple stages, and the tip of the headed pin 8 is fitted through the hole 7a. Through one of the holes 9a, 9b... And projecting from the opposing hole 7b, through the split hole 11 provided at the tip of the headed pin 8, and open the toe of the split pin 11 to pull out. The structure is shown to be eliminated.

In the above-mentioned structure, the male and female fitting portions 4, 5 are determined depending on which of the through holes 9a, 9b.
Can be determined in multiple stages. As a result, the length of the pole can be adjusted in a stretchable manner.

FIG. 2 shows the stopper means 6.
(B) shows a state in which the screw 12 is screwed into a screw hole provided on one side of the lower female fitting portion 4, and the screw 12 is inserted into a corresponding portion of the male fitting portion 5. A groove 13 is provided in which the tip of the male and female fitting portions 4 and 5 can be steplessly adjusted by tightening the screw 12 and abutting the tip against the bottom surface of the groove 13. It can be confirmed.

In the above case, if the bottom surface of the groove 13 is inclined such that the lower side is deeper than the upper side as shown in the figure, the tightening force of the tightening screw 12 is more effectively increased.

The stopper means 6 is not limited to the above two examples, and any other suitable structure may be used freely.

Note that a parent / child diagram A,
B is shown for the purpose of comparing the approximate heights of the poles 3 and does not form a part of the present invention.

[0018]

As described above, the present invention has a pole provided with a lamp at the upper end thereof, and the pole is fitted to a plurality of pole elements having a male and female fitting portion, and each of the male and female fitting portions is fitted to the pole element. Since the stopper means for determining the amount is provided, the pole can be extended and contracted by adjusting the fitting amount of each male and female fitting portion. Therefore, there is an excellent effect that the height of the lamp can be easily changed and adjusted in accordance with the installation site and the surrounding environment even after the external light is installed.

Further, the invention according to claim 2 is characterized in that the pole element is formed such that the upper stage is narrower than the lower stage, so that the external light pole can provide a sense of stability to the exterior, and the street light can have a sense of stability. It has the effect of being able to aesthetically harmonize with the average and landscape.
