Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marker for guiding a visually impaired person laid on a walking road surface.

[0002]

2. Description of the Related Art As shown in FIG. 6, a marker for guiding a visually impaired person has a marker body a formed in a circular shape, an oval shape or the like.
Are laid in a predetermined arrangement on a walking road surface b such as an outdoor sidewalk or an indoor passageway, and are used for guiding visually impaired persons.

In such a marker for guiding the visually impaired, there is a marker using an anchor made of a glass tube filled with an adhesive as one of means for fixing the marker body a to the walking road surface b. As shown in FIG. 4, the anchor c is filled with an adhesive e in an elongated glass tube d and closed at both ends with sealing members f, f. To form a plurality of cuts g. Then, using the anchor c, the marker body a
First, as shown in FIG. 5A, a glass tube d is inserted into a mounting hole h formed in a walking road surface b, and the glass tube d is cut to a predetermined length by a cut g so as to be turned sideways. Then, as shown in FIG. 5B, a screw rod is formed by projecting downward from the upper side of the glass tube d having a predetermined length inserted into the mounting hole h to the lower bottom surface of the marker body a. In a state where the connecting rod i is applied, the marker main body a is hit downward with a tool such as a hammer, and the connecting rod i is hit to the bottom of the hole, so that the glass tube d is broken and the adhesive e is inserted into the mounting hole h. Spread. Then, as shown in FIG.
Thus, the connecting rod i is fixed to the mounting hole h, thereby fixing the marker body a.

[0004]

In the above-mentioned anchor c, since the glass tube d is long, the glass tube d is liable to be broken during transportation due to an impact, and must be cut to a predetermined length at the time of construction. However, there are various problems such as the adhesive e being hardened in the glass tube d if the device is left for a long time during use without being completely used up. Further, as shown in FIG. 5B, a connecting rod i having substantially the same diameter is applied to the glass tube d having a predetermined length inserted into the mounting hole h from above, and the connecting rod i is beaten to the bottom of the hole. Since the glass tube d is broken, most of the crushed glass tube d is pushed down by the connecting rod i and accumulates at the bottom of the hole, and the crushed pieces x are used as aggregates for increasing the bonding strength of the adhesive e. However, there is a problem that the function of (1) cannot be achieved very much.

An object of the present invention is to provide a marker for guiding a visually impaired person which can solve such a conventional problem.

[0006]

According to the present invention, there is provided a marker body having a connecting rod projecting downward from a lower bottom surface, and an adhesive which is screwed to a lower end portion of the connecting rod and which is filled inside by the screwing. And a bottomed cylindrical tube made of an easily crushable material that seals the marker.

Here, materials such as glass, ceramics, and plastics have been proposed as the friable material.
Among them, glass can be used as the most suitable one.

In this configuration, with the bottomed cylindrical tube screwed to the lower end of the connecting rod inserted into the mounting hole formed in the walking road surface, the marker body is fitted with an appropriate tool such as a hammer. By pressing down, the connecting rod is pushed into the bottom of the mounting hole through the inside of the bottomed cylindrical pipe, and the bottomed cylindrical pipe is crushed so as to be substantially uniformly dispersed around the connecting rod, and The internal adhesive diffuses in the mounting holes. Thus, when the adhesive cures, the connecting rod is fixed to the mounting hole, and the marker body is fixed to the walking road surface. In addition, the crushed pieces of the cylindrical tube with the bottom, which are substantially uniformly dispersed around the connecting rod, effectively act as an aggregate for increasing the bonding strength of the adhesive.

[0009] A hardener layer may be formed on the outer peripheral surface of the bottomed cylindrical tube. In this case, the adhesive serving as the main component of the two-component adhesive is filled in the bottomed cylindrical tube,
The curing agent of the main agent is applied to the outer peripheral surface of the bottomed cylindrical tube. When the bottomed cylindrical tube is crushed as described above, the main agent and the curing agent are mixed, and the adhesive can be cured in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.
Will be described.

In the drawings, reference numeral 1 denotes a marker for guiding a visually impaired person according to the present invention. The marker body 2 of the marker 1 for guiding the visually impaired is formed in a predetermined shape such as a circle or an oval (see FIG. 6) in accordance with the standard defined by the regulations. A plurality of connecting rods 3 project downward. The connecting rod 3 may be formed integrally with the marker body 2 or may be formed separately and fixed to the marker body 2 via welding or the like. Also,
A male screw 4 is formed on the outer peripheral surface of the connecting rod 3,
The male screw 4 can be screwed into a female screw 6 of a bottomed cylindrical tube 5 described later.

The bottomed cylindrical tube 5 has a bottom plate portion 5a and is formed into a cylindrical tube capable of being filled with an adhesive 7 therein. The bottomed cylindrical tube 5 is made of an easily crushable material. , Glass, ceramics, plastics and the like. Of these, glass is particularly workable, easily crushable,
It is advantageous in terms of cost and can be most preferably used. Further, the bottom plate portion 5a of the bottomed cylindrical tube 5 may be integrally formed with the side peripheral portion 5b as shown in the figure, or may be constituted by shielding the lower opening of the cylindrical tube with a cap, filling, or the like. Is also good. Further, a female screw 6 that can be screwed with the male screw 4 of the connecting rod 3 is formed on the inner peripheral upper portion of the bottomed cylindrical tube 5, and the female screw 6 and the male screw 4 are screwed together. ,
The bottomed cylindrical tube 5 is screwed to the lower end of the connecting rod 3. Then, the adhesive 7 filled in the bottomed cylindrical tube 5 is sealed by the screwing.

As the adhesive 7, a polyester adhesive which is a main component of a two-component adhesive is used.
On the outer peripheral surface of the bottomed cylindrical tube 5, there is formed a hardener layer 8 formed by applying a hardener which promotes hardening when mixed with the adhesive. Bengel peroxide may be used as the curing agent.

In such a configuration, the marker body 2 is
As shown in FIG. 2, the length of the connecting rod 3 protruding from the lower part of the marker body 2 and the outer diameter of the bottomed cylindrical pipe 5 are fixed to the walking road surface 10 such as an outdoor sidewalk or an indoor passageway. A bottomed mounting hole 11 substantially corresponding to the size is formed in the walking road surface 10, and the connecting rod 3 of the marker body 2 is inserted into the mounting hole 11.
The cylindrical tube 5 with a bottom screwed into is inserted as it is.

Next, when the marker main body 2 is pressed downward by a suitable tool such as a hammer in this state, the connecting rod 3 is pushed into the bottom of the mounting hole 11 through the bottomed cylindrical tube 5,
By this pushing, the bottomed cylindrical tube 5 is crushed, and as shown in FIG. 3, the crushed pieces x are substantially uniformly dispersed around the connecting rod 3, and the adhesive 7 is diffused into the mounting hole 11. Then, the adhesive 7 thus diffused and the curing agent of the curing agent layer 8 adhering to the crushed pieces x of the bottomed cylindrical tube 5 are mixed, and the adhesive 7 is quickly cured. . Here, the crushed pieces x of the bottomed cylindrical tube 5 dispersed substantially uniformly around the connecting rod 3 as described above have an effect as an aggregate for increasing the bonding strength of the adhesive 7.

As a result, the connecting rod 3 is fixed to the mounting hole 11, and the marker body 2 can be fixed to the walking road surface 10.

In the above embodiment, the adhesive 7 which is the main agent of the two-component adhesive is filled in the bottomed cylindrical tube 5 and the hardener is applied to the outer peripheral surface of the bottomed cylindrical tube 5. However, instead of this configuration, the inside of the bottomed cylindrical tube 5 is divided into two chambers and the adhesive 7
And a curing agent, respectively. here,
As in the embodiment, when the adhesive 7 as the main agent is filled in the bottomed cylindrical tube 5 and the hardening agent is applied to the outer peripheral surface of the bottomed cylindrical tube 5, the two-agent separation can be easily configured. There are benefits that you can do.
In addition, it is also possible to fill the bottomed cylindrical tube 5 with the quick-drying adhesive 7 made of one agent, and in this case, the curing agent layer 8 in the embodiment becomes unnecessary.

[0018]

According to the present invention, as described above, the bottomed cylindrical tube 5 made of an easily crushable material filled with the adhesive 7 is connected to the lower end of the connecting rod 3 projecting downward from the lower bottom surface of the marker body 2. , And the adhesive 7 is sealed by the screwing. The bottomed cylindrical tube 5 is directly inserted into the mounting hole 11 formed in the walking road surface 10, and the marker is placed in this state. By pressing the main body 2 downward, the connecting rod 3 is pushed to the bottom of the mounting hole 11 to crush the bottomed cylindrical tube 5, and
Since the adhesive 7 is diffused into the mounting hole 11 and the marker body 2 is fixed by the hardening thereof, the bottomed cylindrical tube 5 is formed in comparison with a conventional elongated glass tube filled with an adhesive. Because it is short, it is less likely to break during transportation,
At the time of the construction, it is not necessary to cut into a predetermined length each time, so that the workability is good. Further, the bottomed cylindrical tube 5 is screwed to the lower end of the connecting rod 3, and the adhesive 7 is sealed by the screwing. Since it is stopped, the curing of the adhesive 7 during storage can be prevented. In addition, crushed pieces x of the bottomed cylindrical tube 5
Can be dispersed substantially uniformly around the connecting rod 3, so that there is an excellent effect that the crushed pieces x can effectively act as an aggregate for increasing the bonding strength of the adhesive 7.

When a two-component adhesive is used, a hardener layer 8 made of the hardener is applied to the bottomed cylindrical tube 5.
There is an advantage that the two-agent separation can be easily configured by forming the outer peripheral surface on the outer peripheral surface.
