Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for detachably fixing a cylindrical illuminator for construction along a single pipe.

[0002]

2. Description of the Related Art Generally, there is a cylindrical luminaire called "Bomboli" as an instrument for illuminating a work zone at an underground site or a work zone at nighttime. This is a protective tube with a built-in fluorescent lamp, which normally divides the work passage from other places, and the construction zone from other places, and the lower part of the single pipe that constitutes the handrail etc. It is temporarily fixed along its length and illuminates the foot of a passage or construction zone, and is also used as a passage marker in the dark field.

[0003]

However, when the lighting fixture is attached, since the single tube and the protective tube are temporarily fixed together by, for example, a numbered wire or an adhesive tape, the numbered wire is used. In addition, it is necessary to bend the handrail (single pipe) to prevent the hand from touching the cut end, which is not only complicated but also in a dark work site. However, there was a risk that hands and clothes would touch the cut end. In addition, when moving the installation location, the number lines are cut or the tape is taken up and removed, which makes the installation and removal work complicated and inefficient. Not only was the management process increased, it was uneconomical. In particular, when the adhesive tape is used, there is a problem that a trace of the adhesive tape peeled off remains on the single pipe, which makes the handrail uncomfortable to touch and unsightly.

Further, since various attachments are made by the workers, when the illuminators have different parallelisms with respect to a single tube and different spacings, they are visually unappealing and a design ingenuity is required.

The present invention has been made to solve the above problems, and its object is to install and remove a lighting device from a single tube with one-touch operation, and also to convert the lighting device into a single tube, which is good in appearance and excellent in design. A fixture for a lighting fixture for a vehicle is provided.

[0006]

In order to achieve the above object, according to claim 1 of the present invention, a cylindrical illuminator arranged substantially horizontally along a single tube is detachably fixed to the single tube. A fixture main body in which a substantially semicircular holding piece corresponding to the cross-sectional shape of the single tube and the lighting fixture is vertically integrated, and a fastening band projecting around the periphery of the fixture main body is removable. And a projection for surrounding the single tube and / or the illuminator in a clamped state by fitting.

According to a second aspect of the present invention, the fixture body is made of an elastic body, and the holding piece is fitted to the outer periphery of the single tube and / or the illuminator while elastically expanding, and in the fitted state. It is characterized in that it is elastically reduced in diameter and held on the outer periphery of the single tube and / or the illuminator.

[0008]

According to the first aspect of the invention, the illuminator can be attached to and detached from the handrail by the attaching and detaching operation with respect to the protrusion of the band. Moreover, the removed mounting fixture is diverted at the time of the rearrangement. The illuminator fixed to the single tube is arranged in parallel along the single tube at a predetermined distance by interposing the fixture body.

According to the second aspect of the present invention, the fixture body itself can be temporarily fixed to the single tube and / or the illuminator, which facilitates the work.

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 3 show a first embodiment of the present invention, FIG. 1 is an exploded perspective view, FIG. 2 is an enlarged view of a main part, and FIG. 3 is an enlarged sectional view of the same. In the figure, reference numeral 1 is a single pipe that constitutes a handrail or the like, and is arranged at the side of a construction passage or along the boundary of a construction zone. A cylindrical illuminator 2 is detachably fixed to the lower portion of the single tube 1 with a proper interval therebetween via a pair of mounting fixtures 3.

The cylindrical illuminator 2 is referred to as a bomboli as described above, and is a transparent or translucent plastic protective tube 2a in which a fluorescent lamp A is disposed, and both ends thereof are covered with caps 2b. The power supply connecting cord 2c of the fluorescent lamp is pulled out from the one cap 2b.

Each attachment device 3 is a device body 4 made of a plastic molded body made of a hard elastic material and a pair of upper and lower fastening bands 5 and 6 detachably fixed to the device body 4.
It consists of The instrument body 4 includes substantially semicircular holding pieces 4a, 4 according to the cross-sectional shapes of the single tube 1 and the protective tube 2b.
Both sides of b are integrally connected by a continuous portion 4c, and mushroom-shaped protrusions 7 are provided on both sides of the outer peripheral portion of each sandwiching piece 4a, 4b.
Are projected integrally. Each of the fastening bands 5 and 6 is made of an elastic body such as soft plastic or rubber, and mounting holes 5a and 6a with slits which are elastically fitted to the respective projections 7 are opened on both sides thereof.

Therefore, in order to attach the lighting device 2 to the single tube 1 by using the attachment device 3 having the above-described configuration, first, one end of the fastening bands 5 and 6 is attached to one protrusion 7 of each of the holding pieces 4a and 4b. deep. In this state, the holding piece 4a is positioned and fitted to the outer periphery of the lower portion of the single pipe 1, and the fastening band 5 is made to circulate half, and its circling end is applied to the other end side projection 7 of the holding piece 4a, and its mounting hole 5a is projected. When the fitting band is fitted, the slit is opened and elastically fitted, and in the fitted state, the slit is closed and prevented from being pulled out from the projection 7, so that the fastening band 5 surrounds and binds the upper side of the single pipe 1. The sandwiching piece 4a is fixed to the lower portion of the single tube 1.

On the other hand, the holding piece 4b is fitted to the outer periphery of the upper end side of the protective tube 2b, and the fastening band 6 is half-turned to apply the other end side to the other end side projection 7 of the holding piece 4b, and its mounting hole 5a. By being elastically fitted to the projection 7, the holding piece 4b side is also fixed to the protective tube 2a. This mounting order may be first.

By performing the above-described mounting operation of the mounting fixture 3 at both ends of the protective tube 2a, both ends of the lighting fixture 2 can be fixed in parallel to the lower portion of the single tube 1 via the mounting fixture 3 in a horizontal state. If the holding piece 4b side is once fixed to the protective tube 2a by the fastening band 6 and then left as it is, the time and effort for subsequent attachment and detachment can be omitted.

In the removal work at the time of reassembling, if one end of each fastening band 5 is pulled, the mounting hole 5a is elastically removed from the projection 7, and the illuminator 2 can be removed from the single tube 1 with one touch. .

A plurality of mounting holes 5a, 6a, ... May be opened on one end side of the fastening bands 5, 6 so as to cope with the difference in diameter of the single tube 1 and the illuminator 2. Further, the fastening bands 5 and 6 can be given a design by making them different in color.

FIG. 4 shows a second embodiment of the present invention. In the figure, the same parts as those in the first embodiment are designated by the same reference numerals, and only newly added portions are designated by different reference numerals. In the figure, both ends 10 and 11 of the holding pieces 4a and 4b have a cross-sectional shape slightly beyond the semicircular cross section of the single pipe 1 and the tube 2a, and are formed in a curved state inward, and Both ends 10, 11 can be elastically expanded. Therefore, both clamping pieces 4a, 4
When b is fitted to the single pipe 1 and the tube 2a, respectively, both ends 10 and 11 are fitted while elastically expanding as shown by the arrow in the figure, and in the fitted state, elastic compression occurs by exceeding the maximum diameter portion. Diameter is fixed to each. Therefore, the instrument body 4 is itself a single tube 1 and a protective tube 2.
The fixing work can be completed by temporarily fixing it to a, and then wrapping the fastening bands 5 and 6 around the outer circumference of the single pipe 1 and the protection tube 2a.

In this embodiment, since the instrument body 3 can be positioned and fixed before the fastening bands 5 and 6 are wound, workability is further improved. Further, the fastening bands 5 and 6 are also unnecessary when firm fixation is not required.

In this embodiment, both holding pieces 4a,
Although 4b is designed to be fitted and held at the mounting location, it goes without saying that only one of them may be fitted.
