Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a Braille stud set on a walking surface.

[0002]

2. Description of the Related Art Braille tacks are installed on a walking surface such as a road surface, a building floor, or the like, to give a predetermined warning to a pedestrian,
For guiding a pedestrian in a predetermined direction, a warning-type Braille tack and a guidance-type Braille tack are known to meet such applications.

[0003] The warning-type Braille tack usually has a circular flat shape and a rod-shaped leg integrally formed on the lower surface thereof, and a display material recessed on the upper surface of the tack. A flat display material made of, for example, a resin material colored yellow or the like is adhered and fixed in the mounting portion, and is mounted on the walking surface by burying and fixing the legs on the walking surface side.
Then, a plurality of such warning braille studs are installed singly or in a predetermined installation pattern.

[0004] On the other hand, the guide-type Braille tack usually has a generally rectangular flat shape having a predetermined length, and has a plurality of rod-shaped legs formed on the lower surface thereof at predetermined intervals in the longitudinal direction thereof. And a substantially long rectangular flat display material made of, for example, a resin material colored yellow or the like is adhered and fixed in a substantially long rectangular display material mounting portion recessed on the upper surface of the tack body. Each of the legs is buried and fixed on the side of the walking surface to be installed on the walking surface.

[0005]

However, in such a conventional braille stud, the stud body is firmly fixed to the side of the walking surface via a leg, but the display material is provided on the upper surface of the stud body. It is originally difficult to control the bonding strength during the bonding operation and to maintain the bonding strength for a long period of time because it is only bonded and fixed to the display material mounting portion.

[0006] For this reason, when the braille studs are installed on a walking surface for use, the display material is gradually peeled off from the stud body side due to being hit by a pedestrian's shoes or being scratched by the shoes. However, not only is it difficult to achieve the intended purpose as a Braille tack, but also, in some cases, a problem occurs that the peeled display material hinders walking. Such a problem was remarkable particularly in the case of a guided braille that has a rectangular display material.

SUMMARY OF THE INVENTION The present invention has been made to provide a braille stud which can prevent peeling of a display material as much as possible.

[0008]

Means for Solving the Problems The present invention employs the following configuration as specific means for solving such problems.

In the first invention of the present application, a metal stud body 1 that is abutted and fixed on a walking surface 31 and an upper surface 1 of the stud body 1
In the case of a Braille tack comprising a display material 2 made of resin that is adhered and fixed to the display material mounting portion 11 provided in a, the display material mounting portion 11 of the tack main body 1 is attached to the display material mounting portion 11. A mounting hole 12 is provided to penetrate the display material 2 in the up-down direction.
Is formed integrally with the display material 2, the display material 2 is adhered and fixed to the display material mounting portion 11 of the tack main body 1, and the mounting legs 22 pass through the mounting holes 12 in a state where they are integrated. The stud body 1 is characterized in that it protrudes toward the back surface 1b.

In the second invention of the present application, in the Braille tack according to the first invention, the display material is attached to the periphery 11b of the display material mounting portion 11 of the tack main body 1 by being hooked to the display material 2. 2 is provided with a detachment restricting means 3 for restricting detachment from the display material attaching portion 11.

[0011]

According to the present invention, the following effects can be obtained by adopting such a configuration.

In the Braille stud according to the first invention of the present application, a metal stud body 1 that is abutted and fixed on a walking surface 31.
And a resin display material 2 adhesively fixed to a display material mounting portion 11 provided on the upper surface 1a of the tack main body 1 in a Braille tack.
The display material mounting portion 11 is vertically inserted through the mounting hole 12.
While the back surface 2b of the display material 2 is provided on the back surface 2b.
A mounting leg 22 is formed integrally with the display material 2, and the display material 2 is adhered and fixed to the display material mounting portion 11 of the stud body 1, and the mounting leg 22 is integrated therewith. Project through the mounting hole 12 to the back surface 1b side of the stud body 1.

Therefore, according to the Braille tack of the present invention, when the Braille tack is installed on the walking surface 31 side, the mounting leg 22 of the display material 2 protruding toward the back surface 1b of the tack main body 1 is walked. By fixing to the surface 31, the display material 2 is directly fixed to the walking surface 31 with the tack main body 1 interposed between the display material 2 and the walking surface 31.

For this reason, the display material 2 is connected to the tack main body 1.
For example, due to the synergistic effect of the adhesive action to the display material mounting portion 11 and the fixing action to the walking surface 31 side, for example,
Even if the bonding strength of the display material 2 to the display material mounting portion 11 is not sufficient, or if the display material 2 has been subjected to a striking or scratching action from the pedestrian for a long period of time, Separation from the material mounting portion 11 is prevented as much as possible, and even if the display material 2 is peeled off, the floating of the display material 2 from the stud body 1 side is suppressed as small as possible. In particular, it is reliably prevented that the peeled display material 2 is detached from the stud body 1 side, and as a result, the durability and the safety in use of the braille stud are remarkably enhanced.

In the second invention of the present application, in the Braille tack according to the first invention, the display material is attached to the periphery 11b of the display material attachment portion 11 of the tack main body 1 by being hooked to the display material 2. 2 is provided with a detachment restricting means 3 for restricting detachment from the display material mounting portion 11, so that the display material 2 has an adhesive effect of the tack main body 1 to the display material mounting portion 11 and the walking surface 31. In addition to the fixing action on the side, the detachment restricting action by the detachment restricting means 3 works, and the peeling and detachment of the display material 2 from the stud body 1 from the display material mounting portion 11 can be more reliably prevented.
