Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the improvement of a band used for mounting road traffic signals, particularly pedestrian signals.

[Conventional technology]

Conventional bands of this kind, when wrapped around a support,
It was fastened with commonly used bolts and nuts.

Therefore, even when firmly tightened, the signal often loosens during long-term use, making the installation of the traffic light unstable.

[Problem that the invention attempts to solve]

Therefore, with this invention, the band can be firmly tightened and fixed to the pillar, and it will not loosen even when used for a long time, and can be removed as necessary, making it possible to maintain a stable mounting condition for road traffic signals over a long period of time. It is an object of the present invention to provide a band for mounting a traffic light that can be obtained.

[Means for solving problems]

To this end, in this invention, connecting portions are formed facing each other at appropriate intervals at the rear ends of the bands curved into an arc shape corresponding to the peripheral shape of the support, and the head of the bolt is attached to one of the connecting portions. A nut is screwed onto the bolt at the other connecting portion, and a recessed groove having a U-shaped cross section is formed inside the nut, and the groove is inserted into the connecting portion. A band for attaching a traffic light is attached to a protrusion with a U-shaped cross section provided on the outside.

[Function] The traffic light mounting band having the above-mentioned configuration has two opposing connecting parts spaced apart from each other by bolts to tighten and fix them, and the heads of the bolts have a non-rotating structure. On the other side of the bolt, the convex part of the plate engages with the groove of the nut, so there is no risk of the nut turning in the direction of loosening, and the bolt
The tightened state of the nut will not loosen, and
When the nut is turned strongly in the direction of loosening if necessary, the groove and the convex part are both locked in a U-shaped cross section, and the connecting part has some elasticity due to the appropriate spacing at the rear end of the band. The nut can be removed by climbing over the convex portion and turning in the direction of loosening, so that the signal can be firmly and stably attached to the support even after long-term use.

〔Example〕

The configuration of this invention will be explained below with reference to the drawings showing examples.

Reference numeral 1 denotes a post, which is erected on a road or the like, and a traffic light 6 is attached to this post 1 via a band 2, a connecting fitting 3, an arm 4, and a hanging fitting 5.

The band 2 is formed into an arcuate shape corresponding to the peripheral shape of the support column 1.

At the rear end of this band 2, connecting portions 7 and 8 are formed facing each other with an appropriate interval.

A head 10 of a bolt 9 is inserted into the one connecting portion 7 so as to form a rotation preventing structure.

That is, in the illustrated embodiment, the bolt 9 insertion hole 11 of the connecting portion 7 is formed in a polygonal shape, and an inner flange 12 having a shape matching the polygon is formed inside the head 10 of the bolt 9. .

Therefore, when the inner flange 12 and the insertion hole 11 are engaged with each other, the bolt 9 has a rotation preventing structure and is inserted into the connecting portion 7.

The bolt 9 inserted through the other connecting portion 8 is
The nut 13 is screwed together.

A plate 15 with a convex portion 14 is disposed on the connecting portion 8, and a groove 16 is formed inside the nut 13, and the groove 16 is engaged with the convex portion 14 of the plate 15.

This nut 13 is installed by locking the groove 16 to the convex portion 14, so it needs to be tightened somewhat strongly, but once it is locked with a strong tightening force, it can be turned in the strong opening direction. There is no risk of it loosening unless force is applied.

The embodiment shown in FIG. 3 shows a state in which the upper and lower edges 17 of the connecting parts 7 and 8 are bent outward, and the embodiment shown in FIG. This shows the state bent inward.

In the embodiment shown in FIG.
The nut 13 is secured to the convex portion 19 formed on the connecting portion 8.
The groove 16 of the nut 13 is locked to prevent the nut 13 from loosening.

In each of the illustrated embodiments, a recessed groove 16 with a U-shaped cross section is formed inside the nut 13, and the groove 16 engages a convex portion 19 with a U-shaped cross section provided on the outside of the connecting portion 8. Although it has a locking structure, when the nut 13 is strongly turned in either the tightening direction or the opening direction, the groove 16 goes over the convex part 19. Furthermore, since an appropriate interval is formed at the rear end of the band, the connecting portion has some elasticity. Therefore, in all of the above-mentioned embodiments, once the nut 13 is tightened, it has a locking structure as described above, but when the nut 13 is strongly turned in the opening direction, the nut 13 climbs over the convex portion 19 and the tightened state is loosened. fields become possible.

[Effect of idea]

This invention has the above-mentioned structure, and therefore, the band can be strongly tightened and fixed without the risk of loosening, and it can also be used in various fields as needed, so that the signal can be used for a long period of time. It can be installed in a stable state.
