[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a street light, and more particularly, to a mounting structure for an arm that suspends or stands a street light and a pole for the street light.

[0002]

[Prior art]

 In the past, street lamp arms and poles were often attached by welding the arm directly to the pole. There was also a screwing type attachment means, but in this case as well, it was completely fixed so as to withstand large gravity, and could not be easily removed, but it was an integral part like welding.

Therefore, in the case of a so-called single-lamp system in which only one street light is attached to one pole, the volume is not so large because the connection between the arm and the pole is flat, but one 2 or 3 street lights with 2 or 3 street lights attached at the same height on the pole will be three-dimensional because multiple arms are attached with an opening of 45 degrees or 60 degrees, and its volume Will be very large.

Conventionally, since the pole and the arm are integrated by welding or screwing as described above, a large plating tank or equipment for a coating device is required for plating or painting, and much less. The two- or three-lamp system became three-dimensional and required significantly larger equipment.

Further, the two-lamp type and three-lamp type street lights require a large volume for packing, transporting, etc., are difficult to handle and costly, and installing the street lights on the road is also a difficult task. The workability and workability were also very poor.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to solve the problems of the conventional street lights as described above. It is also possible to attach or remove the arm after it has been erected, the pole and arm can be standardized separately, and the painting and plating equipment can be small, and packing, transportation, storage, stockability, and work can be done. It aims to provide a new type of attachment / detachment mounting structure for a streetlight arm, which has a great effect on workability, workability, and cost.

[0007]

[Means for Solving the Problems]

 As a result of various studies to achieve the above purpose, the arm was fixed to the long plate flange, and a mushroom-shaped projection was provided on the back side of the long plate flange with respect to the arm fixing surface, and this projection was drilled in the pole. It has been found that a very suitable detachable structure can be obtained by inserting it into the attachment / detachment hole with the elongated hole and lowering it to form the elongated hole portion to receive the projection.

That is, according to the present invention, an arm for mounting a street light is fixed to a long plate flange by welding or the like, and at least two or more mushroom-shaped projections are provided on the back surface of the long plate flange at appropriate intervals. The long plate flange with the arm is attached to the pole by inserting the mushroom-shaped projection into the attachment / detachment hole formed in the pole for reception and receiving it by the downward long hole provided in the attachment / detachment hole. The gist is a detachable mounting structure of a street light arm, which is characterized by the above.

The present invention will be described in detail with reference to the drawings with reference to embodiments. FIG. 1 is a schematic side view showing an outline of one embodiment of the present invention. As shown in this figure, the present invention relates to a mounting structure of a pole (2) standing for installing a street light (1) and an arm (3) to which the street light (1) is directly mounted. (3) is detachably attached to the pole (2) through the long plate flange (4). The pole (2) and the upper arm (3) are pipe-shaped and have wiring inside to energize the electric lights in the street light (1). . (See Figure 6)

FIG. 2 is a rear view showing an embodiment of the long plate flange according to the present invention. FIG. 3 is a sectional view taken along line AA of FIG. FIG. 4 is a plan view of FIG.

As shown in these figures, at least two mushroom-shaped projections (5) are provided on the back surface of the long plate flange (4) in the present invention by welding or the like. As shown in FIGS. 3 and 4, the arm (3) is fixed to the front side of the long plate flange (4) by welding or the like. (Since the upper arm (3) is a square pipe in this embodiment, the thicknesses of FIGS. 3 and 4 are different.) Also, (6) of the figure is used as necessary. A screw hole is shown, and similarly (11) is a wiring hole.

FIG. 5 is a front view showing an embodiment of the pole according to the present invention. As shown in this figure, the pole (2) of the present invention is provided with a mounting hole (7) at a position corresponding to the mushroom-shaped projection (5), and below the mounting hole (7). A long hole (8) continuous with this is provided. The elongated hole (8) is preferably tapered as shown in the figure. If necessary, a female screw (9) is provided at a position corresponding to the screw hole (6), and a hole (11) for wiring is also formed in this pole (2).

When the elongated plate flange with arm (4) shown in FIGS. 2 to 4 is inserted into the attachment / detachment hole (7) of the pole (2) and pushed down, The long hole (8) receives the mushroom-shaped projection (5), and the long plate flange (4) is attached.

FIG. 6 is an enlarged partial cross-sectional view of one embodiment showing that the mushroom-shaped projection is received in the slot. As shown in this figure, the mushroom-shaped projection (5) has a thin root and a mushroom-shaped head, and if the front of this head is an umbrella-shaped attachment (7) ) Is easy to insert, and if the back side of this head is tapered like an inverted cone, it can be stably received while it is biting into the long hole (8). In addition, when the fixation of the pole (2) and the long plate flange (4) is reinforced by the screw (10), when the mushroom-shaped projection (5) is received in the long hole (8), it is just screwed hole (6). Of course, it is necessary to design so that the positions of () and the female screw (9) match. (In FIG. 6, the thickness of the arm (3) through which the wiring (12) is inserted is drawn smaller than the others because of the limitation of space.

In the present invention, in the case of the one-lamp type, the pole (2) may be provided with a detachable hole (7) with two or more long holes (8) in one row vertically, but the two-lamp type In the case of, the two holes vertically, in the case of the three-lamp type, three rows vertically, with the attachment / detachment holes (7) and the like at the same height position at an appropriate angle of 45 to 90 degrees according to the design You can leave it. Then, after the pole (2) is erected, the long plate flange (4) with the arm can be attached to the corresponding attachment / detachment hole (7) or the like. It can be easily installed even with multiple lights.

The long plate flange (4), the mushroom-shaped projection (5), the attachment / detachment hole (7), the elongated hole (8), and other dimensional objects, or the mushroom-shaped projection ( The number of 5) and the like may be appropriately designed according to the size and number of street lights (1) and the thickness and height of poles (2). However, the number of the mushroom-shaped projections (5), the corresponding attachment / detachment holes (7) and the corresponding long holes (8) must be at least two or more for one long plate flange (4), so that it is stable. It goes without saying that it cannot be installed.

[0017]

[Action]

 The present invention is constructed as described above, and the pole (2) and the arm (3) are detachable. Therefore, the pole (2) is erected first and then the arm (3) is fixed. Since the long plate flange (4) can be removably attached to the pole (2), it exerts a very excellent effect.

First, since the long plate flange (4) with the pole (2) and the arm (3) can be manufactured separately, the equipment for plating or painting these is small regardless of whether it is a single light type or a multiple light type. However, the workability is very suitable. In addition, since the volume is small in packing, transportation, and storage, it is very effective in terms of space and is suitable for cost reduction.

Further, since the pole (2) and the long plate flange (4) with the arm (3) can be standardized and manufactured separately according to various purposes of use, the purpose can be achieved by arbitrarily combining these. It is possible to easily obtain the street lights to be used and mass-produce and stock these standardized poles and arms, shorten the delivery time, and standardize to improve quality evenly. Also becomes advantageous.

Further, for further construction, since it can be assembled on-site, a large crane vehicle etc. is not required, work efficiency is improved, wiring is easy, and the arm is removed even during repair or repair. It is very convenient because it can be done.
