DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to provide a visually impaired person with a warning of danger during walking, by coating a large number of button-shaped protrusions having a circular outer periphery on a flat band-shaped line constructed on a road surface with paint. The present invention relates to a method of constructing a round cognitive road line for laying warnings for visually impaired persons.

[0002]

2. Description of the Related Art Generally, a road line for the visually impaired is provided with a guide road line in which a number of rib-shaped protrusions having a rectangular outer periphery are provided on a band-like line, and a number of button-shaped protrusions having a circular outer periphery. Marked in combination with the warning round cognitive road line, the visually impaired walks along the guidance road line, and places where normal walking cannot be performed on the warning round cognitive road line, that is, stairs, platforms And the like, and recognizes a danger zone or a crossover portion.

[0003] Conventionally, a warning round perceived road line for warning of this danger is provided by arranging square tiles having a large number of button-shaped protrusions formed on the surface in advance on the road surface, or by providing button-shaped protrusions. The mainstream is a method in which a sheet-like object having many objects on the surface is adhered one by one to a road surface by an operator.

In recent years, Japanese Patent Application Laid-Open No. Hei 7-138921 discloses a method of constructing a round cognitive road line for warning a visually impaired person directly on a road surface using a paint mainly composed of a thermoplastic resin. A heat-fusible material having a thixotropic property at a site is caused to flow out of a line forming outlet of a storage tank containing the heat-fusible material to form a line having a predetermined width. A road surface line laying method in which an opening of an outlet is controlled so that a protrusion is integrally formed on the line, an outlet for forming a protrusion is provided, and a laying member having an opening / closing body for opening and closing the opening intermittently is provided. It is disclosed to lay button-like projections on the device.

Further, in Japanese Unexamined Patent Application Publication No. 9-170209, a warning type marking line for forming a large number of button-shaped projections having a circular outer periphery is constructed by previously forming a flat line of a predetermined width of 1 to 3 mm on a road surface. Then, a 4-6mm thick template with a large number of truncated cone holes is placed on top of it, and a thermoplastic paint is poured from above the template to form a large number of button-shaped projections. A method has been proposed.

In Japanese Patent Application No. 9-348556, a button-shaped projection is formed so that a template placed on a road surface can be injected in a non-contact manner and an appropriate amount of paint can be injected into a mold hole of the template. A construction apparatus capable of forming an accurate button-shaped projection is disclosed.

[0007]

However, of the above-mentioned conventional construction methods, the methods of arranging tiles having button-shaped projections formed in advance and joining or bonding the projection sheets are all troublesome. It is time-consuming and costly. In particular, it is difficult to arrange them neatly in a line and necessitate a large number of operators, and there is a problem in workability.

On the other hand, in JP-A-7-138921, it is very difficult to control the fluidity of the thermoplastic paint and the opening of the protrusion forming outlet, and if the fluidity is good, the paint will flow easily.
If the height of the button-shaped projections cannot be secured and the fluidity is not good, it takes time and there is a problem in workability. Also, even if the protrusion forming outlet is intermittently opened and closed by the opening and closing body, the outer periphery does not become a completely round button-like protrusion, and since the method is formed more naturally, the shape of each button-like protrusion varies. Yes, it is very difficult to lay clean lines.

In Japanese Patent Application Laid-Open No. 9-170209, since the road surface is not completely flat, the road surface does not completely adhere to the template and the template floats off the road surface. Leakage from the template causes an obstacle to drawing a clean line, and the problem that the cleaning of the template requires time and effort remains.

In Japanese Patent Application Laid-Open No. Hei 9-348556, there is an advantage that an accurate button-shaped projection for injecting an appropriate amount of paint into a mold hole of a mold plate can be formed, and the mold plate can be easily maintained. However, it is necessary to sequentially move a template of a certain size and place it on the road surface, and it takes time and effort to place the template, during which the construction work of protrusions is interrupted, However, there is a problem that it is not possible to perform a proper construction, the workability is poor, and an extra time is required for loading and unloading the template to and from the construction site.

The present invention has been developed in view of the above-mentioned conventional problems, and all of the button-shaped projections to be formed can have the same and accurate shape, and can be laid on the road surface continuously and in a short time. An object of the present invention is to provide a method of constructing a round cognitive road line for warning visually impaired persons that can be formed.

Another object of the present invention is to provide a method for constructing a round cognitive road line for warning a visually impaired person, in which the button-shaped projection does not come off the road surface.

[0013]

SUMMARY OF THE INVENTION According to the present invention, a round cognitive road for warning the visually impaired is formed with a thermoplastic paint by forming a number of button-shaped projections (2) on a flat strip-shaped line (1). In the method of constructing a line, the band-shaped line (1)
A rectangular projection (3) larger than the button-shaped projection (2) was previously formed at a position where the button-shaped projection (2) was to be formed, and the square-shaped projection (3) was solidified. Later, the square projection (3) is cut into the button-shaped projection (2).

It is explanatory drawing which performs cutting in a staggered shape.

In this figure, first, a flat strip line (1) having a thickness of 1.0 to 3 mm is formed on a road surface with a thermoplastic paint. Then, at the position where the button-shaped projection (2) is formed on the strip-shaped line (1) shown in FIG.
A rectangular projection (3) is formed which is appropriately larger as a whole than the button-shaped projection (2) (see FIG. 2). In this case, it is preferable that the rectangular projections (3) are integrally formed simultaneously with the belt-shaped line (1). Further, in order to form the rectangular projections (3) integrally with the belt-shaped line (1), by using the road lane marking construction device of Japanese Patent Publication No. Hei 8-16322 previously proposed by the present inventor, Strip line (1)
A rectangular protrusion (3) can be formed simultaneously and integrally on the top,
Moreover, the rectangular projections (3) constructed by the road lane marking construction apparatus can be constructed accurately and quickly even at the shape and the position where they are formed.

The rectangular projections (3) solidify in about 5 to 7 minutes. After this solidification, a square projection (3)
Is cut by a cutting device (4) in which a plurality of cutting tools (5) shown in FIG. 5 are arranged, and the entire button-shaped projection (2) is sequentially formed.

The cutting process will be described in more detail. As shown in FIG. 1, a cutting tool (5) is arranged in a cutting device (4) in a row at right angles to the traveling direction indicated by the arrow. This is a cutting method in which one horizontal row of the rectangular projections (3) is simultaneously cut and formed as a whole on the button-shaped projections (2).

As shown in FIG. 6, it is preferable that the cutting tools (5) are arranged in a staggered manner in the cutting device (4), and the square projections (3) are sequentially cut in a staggered manner. In this case, the space between the cutting tools (5) arranged in the cutting device (4) can be widened, and the space for the rotating means and the feeding means (not shown) for the cutting tools (5) can be widened. They can be easily incorporated into the cutting device (4). In the zigzag pattern, the zigzag form is selected as appropriate for the arrangement of the square projections (3) one by one.

As shown in FIG. 5, the cutting tool (5) comprises a plate-shaped cutting blade (5a) and a holder (5b) fixed on the cutting blade (5a), and the tip of the cutting blade (5a) is button-shaped. The protrusion (2) is formed on the blade portion (5c) having a vertical cross-sectional shape. This cutting tool (5) is rotated as shown by an arrow (not shown).
Is rotated by a feed means or the like (not shown) from above the rectangular projection (3) to below, and the rectangular projection (3) is held by the blade portion (5c) of the cutting blade (5a), Cut the outer periphery and upper surface. Therefore, the obtained button-shaped projection (2) has a very accurate shape, a smooth surface, and an accurate interval as shown in FIG.

In the above-mentioned cutting, the cutting device (4) may be one in which cutting tools (5) that can be vertically moved while rotating at least are mounted in a horizontal row or in a staggered manner. The rotation driving means and the feeding means may be designed as appropriate. Also, the cutting device (4)
Detects a rectangular protrusion (3) cut by a self-propelled type with a position sensor, stops the movement of the cutting device (4), and simultaneously starts cutting of the rectangular protrusion (3), At the end of machining, the cutting device (4) is moved by one pitch of the square projection (3) at a time, and the cutting tool (5) automatically cuts the square projection (3) sequentially into the button-like projection (2). Processing is also possible. Further, the cutting tool (5) shown in FIG. 5 is not limited to this shape, and may be, for example, a cylindrical reamer or the like. In other words, it can cut a square projection (3) into a button-shaped projection (2). Then it is good.

FIG. 4 is a process diagram showing the process sequence of the present invention. As described above, the process diagram (a) shows the first step (a) for constructing the strip line (1) on the road surface, and the strip process. A second step (b) of forming a square projection (3) on the line (1), and a third step (cutting of the square projection (3) to form a button-shaped projection (2) ( C) A processing method comprising: The process diagram (b) shows a first step (d) in which the strip-shaped line (1) and the square projection (3) are simultaneously formed integrally, and a second step (e) in which the button-shaped projection is formed by cutting. ).

[0025]

Since the present invention is the above-mentioned processing method,
It has the following effects.

According to the present invention, as described above, when the rectangular projection (3) is installed on the strip-shaped line (1),
Focusing on the fact that the construction can be performed automatically by using the road division line construction device of No. 16322, the square projection (3) is cut later to form a button-shaped projection (2). For this reason, the square projections (3) can be automatically formed at the positions of the button-shaped projections (2), and can be formed integrally with the strip-shaped line (1). Therefore, the button-shaped projections (2) obtained by cutting the square-shaped projections (3) are extremely accurate in arrangement and shape, and particularly, at the root and upper edges of the button-shaped projections (2). There is no deformation at all and the entire surface is finished smoothly.

The button-shaped projection (2) is a rectangular projection (3) which can be formed integrally with the strip-shaped line (1).
The button-shaped projection (2) is integrated with the band-shaped line (1) since it is cut after forming the square-shaped projection (3) on the band-shaped line (1).
In the present invention, the bonding between the band-shaped line (1) and the rectangular protrusion (3) is extremely strong, and the button-shaped protrusion (2) is hardly detached from the band-shaped line (1). .

Further, in the present invention, since the rectangular projection (3) to be applied first is cut later, there is no problem even if the shape is slightly deformed. In addition to the processing of the object (3), there is an advantage that the paint that has fallen on the strip-shaped line (1) near the rectangular projection (3) can be removed by cutting.
