Description

[Detailed description of the invention] The present invention is a portable sign for construction regulations, and the part where the sign is displayed is replaced with a metal plate by a sheet of cloth or resin, and the part to which this sheet is attached and detached is made of a wire frame. This aims to reduce the weight, make it more versatile, and reduce the wind pressure during transportation of the sign by letting it escape through the space inside the wire frame.Ribs are fixed inside the wire frame that regulates the outer shape, This rib is attached to the post via a fixture to integrate the wire frame and the post, and a sign is displayed on the part that should be located on the front side of the wire frame and attached to the appropriate place on the part that should be located on the back side of the steel frame. By stretching the elastic tension material between the locking holes via a locking tool or removing the bulk of the sheet provided with the locking holes, the sheet can be removably attached to the wire frame, and the wind pressure applied during transportation can be absorbed. The method is characterized in that the sheet is moved and released through the space inside the wire that appears.

Traffic regulations are necessary for construction work on expressways that are in use.

For example, the number of restrictions per year on the 250 km stretch of the Tomei Expressway within the Tokyo Metropolitan Area reaches approximately 8,000.

All regulations other than road shoulder regulations are implemented by installing various regulation signs in the median strip.

In this case, a sign carrier is parked on the roadside, a person carries the sign, crosses the main road, and secures it to the median strip.
There are the following problems.

(1) The heavy weight of the regulatory sign makes it difficult to cross the main line quickly, which poses a great danger.

(2) The wind resistance against the sign board is large, making it difficult to transport it during strong winds.

(3) Due to the frequent installation and removal of signs and easy handling, the boards become extremely dirty and damaged.
The sign becomes unclear.

The present invention solves the above-mentioned problems, and the embodiment thereof will be described in detail with reference to the drawings as follows.

Note that reference numerals in the middle of the drawings indicate the same or corresponding parts.

Reference numeral 1 denotes a wire frame made of, for example, piano wire, which is appropriately bent or curved to form an appropriate external shape such as a circle or a corner.

2 is a rib located within this frame 1, and its end portion is fixed to the frame 1.

If the ribs 2 cannot be directly fixed to the frame 1, a mounting auxiliary material 3 is attached to the frame 1, and the ends of the ribs 2 are fixed to this auxiliary material 3.

Reference numeral 4 denotes a column to which the rib 2 is attached via an ordinary ring-shaped fixture 5.

In the illustrated case, the rib 2 has reinforcing cross-sectional protrusions 6a and 6b facing each other in the longitudinal direction on the back surface, and the leg pieces 8 of the fixture 5 are fitted into the grooves 7 formed therein. A nut 11 is screwed onto a bolt 10 passing through the ear piece 9 to fix the rib 2 to the support column 4.

A sheet 12 is made of cloth or resin, and a sign 14 is displayed on a portion 13 that should be located on the front side of the wire frame 1, that is, on the side facing the driver of the vehicle.

Generally, the mark 14 is displayed on the front side of the portion 13, but if the sheet 12 is transparent, it may be displayed on the back side.

A locking hole 16 is provided at an appropriate position in a portion 15 of this sheet 12 that should be located on the back side of the wire frame 1.

Reference numeral 17 is an elastic tension material that is stretched between the locking holes 16 of the portion 15 located on the back side of the wire frame 1 via locking tools 18, and the sheet 12 is stretched around the frame 1 by this tension.

The locking tool 18 may be attached to the end of the tension member 17 in advance, but if the tension member 17 is made separate and has a ring shape, a wheel chain attachment method can be adopted in this case.

Portion 15 of the sheet 12 that should be located on the back side of the wire frame 1
Assuming that a part of the sheet 12 is a bag-like part 21 that covers the wire frame 1, if the bag-like part 21 is first placed over the frame 1 when attaching the sheet 12, the sheet 12 will remain in the frame 1 even if the sheet 12 is removed. Since the tension member 17 is hooked on the tension member 17, the installation work is facilitated.

Furthermore, if the position of the bag-shaped portion 21 is determined in advance, for example at the top, the sign 14 can be easily attached to the frame 1 by simply attaching the sheet 12 to the frame 1 without having to visually check the upright state of the sign 14.
It is possible to ensure that the erect state of the body is maintained.

In the illustrated sign body, the sheet 12 is stretched over the frame 1 via the tension material 17 and transported to the installation location in the construction regulation area, and the support 4 is installed.

In addition, when the wind is strong, the sheet 12 is removed from the frame 1 or wrapped around a part of the frame 1, and the sheet 12 is moved and carried to a designated location where the tension material 17 is attached to the frame 1. , and establish the support column 4.

If you want to change the content, type, etc. of sign 14, please use sheet 12.
Just remove it and stretch another sheet in the same way.

Furthermore, if the sign 14 becomes soiled and cannot perform its function satisfactorily, it can be removed from the frame 1 and replaced with a new one.According to the present invention, the frame that regulates the external shape is constructed using wire rods,
By attaching a sheet with a sign to this frame, it is much lighter than the conventional aluminum sign plate type, and when the wind is strong, by moving the sheet, the wind pressure can be released through the space inside the wire frame. It can be transported safely with as little impact as possible, and if you want to change the content or type of the sign, it can be easily attached and removed, and the sheet can be updated easily and inexpensively.
It has various effects.
