Description

[Detailed Description of the Invention] The present invention relates to a traffic light attachment band for attaching a traffic light to a post.

Traditionally, traffic light attachment bands have been made to allow installation by adjusting the inner diameter according to the outside diameter of the support, so they have two parts: a band piece on the support member side that supports the traffic light, and a tightening band piece that is tightened and fixed to the support post. Each band piece is divided into two parts, each band piece is provided with a plurality of engaging parts, and the two band pieces are overlapped at the engaging part at a position that corresponds to the outer diameter of the support column, engaged with each other using a bolt, and then tightened. It was fixed to the column with bolts at the tightening part provided in the column. Such conventional traffic light mounting bands use bolts and nuts to engage the two divided band pieces, resulting in poor work efficiency and inconvenience in handling when carrying the band onto a support post during installation.

The present invention was made to eliminate the above-mentioned drawbacks, and includes providing a plurality of engaging parts that overlap each other on both the traffic light side band piece and the tightening band piece, and furthermore, a hole is bored in the tightening band piece. However, by forming a locking part on the signal side band piece that is inserted into the hole and locked, both band pieces can be easily engaged and the inner diameter can be freely adjusted. It provides a band.

Hereinafter, the present invention will be explained with reference to illustrated embodiments. In FIG. 1, 1 is a traffic light side band piece, and 2 is a tightening band piece.

As shown in FIGS. 2 and 3, the traffic light side band piece 1 is made of a single metal plate having an arc shape, and has an annular portion 3 bent inward at one end to be fixed to a traffic light support member. A plurality of protrusions 4 are formed outwardly on the other end side, and a substantially T-shaped elongated hole 5 is formed in the middle part thereof, with its wide part 6 facing toward the annular part 3. to drill. The elongated hole 5 allows the locking portion of the tightening band piece 2 to be inserted therein, and has a required length necessary for adjusting the inner diameter of the traffic light tightening band.

As shown in FIGS. 4 and 5, the tightening band piece 2 has an arc shape having approximately the same radius as the traffic light side band piece 1, and one end thereof is bent to form a tightening part 7. The tightening portion 7 is provided with reinforcing ribs 8 on both sides, and furthermore, a square hole 9 for insertion of a tightening bolt is bored in the center portion. Further, by providing notches 10 on both sides near the other end, a locking part 11 that protrudes on both sides is formed in front of the notch, and furthermore, at the tip thereof,
A T-shaped retaining means 12 is integrally provided. The width of the wide end portion 12a of the retaining means 12 is slightly narrower than the width of the wide portion 6 of the elongated hole 5, and the width of the wide end portion 12a of the retaining means 12 is slightly narrower than the width of the wide portion 6 of the elongated hole 5. The width of the connecting portion 13 with the stop portion 11 is also slightly narrower than the width of the elongated hole 5. Furthermore, the retaining means 12 is bent outward as a whole, and its wide portion 12a is further bent slightly inward. A tightening band piece 2 is placed between the tightening part 7 and the locking part 11 with a traffic light side band piece 1.
A plurality of protrusions 14 are provided at positions where they can overlap with each protrusion 4 provided on the traffic light side band piece 1 when brought into contact from the outside.

A case in which a traffic light is attached to a support using both band pieces 1 and 2 having the above configuration will be explained with reference to FIGS. 1A and 1B. A traffic light (not shown) is held from above and below by traffic light support fittings 15 via arms and fixed with bolts. The traffic light support fitting 15
A flange 17 is provided on both sides of the half cylinder 16, and on the support side of the flange 17, there is an upright part that stands upright at an angle approximately along the outer diameter of the support, and a flange whose tip is bent toward the flange 17 side. A bent portion 18 parallel to 17 is provided in series. Above flange 17
A notch is provided in a portion overlapping with the bent portion 18 into which the annular portion 3 of the traffic light side band piece 1 can fit. The signal side band 1 has the annular portion 3 between the bent portions 18 located above and below the abutting flange 17, with the signal sandwiched between the signal support fittings 15 via the arms. are fitted, and a bolt is inserted into the hole drilled in the bent portion 18 and into the annular portion 3 to be screwed together.

When the tightening band piece 2 is placed horizontally in the elongated hole 5 of the traffic light side band piece 1 fixed to the traffic light support fitting 15 as described above, the stopper means 1 on the tip side thereof is inserted.
2 and the locking part 11, and after rotating the tightening band piece 90 degrees at the notch 10, both band pieces 1 and 2 are inserted.
When the distal end wide portion 12a of the retaining means 12 is aligned with the wide portion 6 of the elongated hole 5, the retaining means 12 is bent outward, so that it cannot escape to the outside of the hole. Can be done. Next, by shifting the tightening band piece 2 toward the tip of the traffic light side band piece 1, the main part of the tightening band piece 2 and the retaining means 12 are moved to the outside of the traffic light side band piece 1, and the locking part 11 is moved to the outside of the traffic light side band piece 1. In this state, the widths of the connecting portions 13 and the narrow portions 12b at the front and rear of the locking portion 11 are approximately equal to the width of the elongated hole 5. The movement is restricted and does not rotate, so the locking part 11 does not come off from the elongated hole 5.

Therefore, the traffic light side band piece 1 and the tightening band piece 2
The two band pieces 1 and 2 are brought together onto a support post, and the positions of the protrusions 4 and 14 of both band pieces 1 and 2 are adjusted according to the outer diameter of the mounting position of the support post, and the band pieces 1 and 2 are overlapped. Next, a bolt is inserted between the tightening parts 7 and 7, and is fastened and fixed.

Therefore, the traffic light attachment band according to this embodiment is as follows:
Both band pieces 1 and 2 can be easily engaged, and the inner diameter can be freely adjusted on the support, and since the retaining means 12 is formed, both band pieces 1 and 2 can be easily engaged.
There is no risk that the two will come apart even if you lift them onto the support column while they are combined.

As described above, in the present invention, a plurality of concave and convex engaging parts are provided at a predetermined interval on the distal end side of the traffic light side band piece, and a concave and convex engaging part that overlaps with the above engaging parts is provided on the distal end side of the tightening band piece. Furthermore, a T-shaped elongated hole with a wide part on the proximal end is bored in the middle part of the traffic light side band piece, while a cut is made from both sides on the distal end side of the tightening band piece so that it overhangs on both sides. A locking portion is formed, and a T-shaped retaining means is integrally extended thereto, and the T-shaped retaining means and the cut width are slightly wider than the T-shaped elongated hole of the traffic light side band piece. Since the tightening band piece has a configuration in which the tip of the tightening band piece is curved outward, the tip of the tightening band piece is inserted into the T-shaped elongated hole of the traffic light side band piece from the outside. By doing so, the two band pieces can be easily connected using the locking parts projecting on both sides as fulcrums, and the inner diameter of the band can be arbitrarily adjusted according to the multi-stage expansion/contraction engagement by the plurality of concave and convex engaging parts of both band pieces. There is an effect that can be performed on the pillar. Moreover, in the connected state, the connecting portion of the tightening band piece with the T-shaped elongated hole width portion of the traffic light side band piece, which is formed by the T-shaped retaining means width portion and the notch, fits into the T-shaped elongated hole width portion of the traffic light side band piece. Since both band pieces are prevented from coming apart due to rotation, and the retaining means at the tip of the tightening band piece is abutted from the outside, there is no risk of the two band pieces coming off, and the two band pieces can be mounted on the support in a connected state. It has the advantage of being able to carry out lifting work, etc.
