[0002]
[Prior art]
As shown in FIG. 6, the visually-impaired person guidance marker lays a marker body a formed in a circular shape, an oval shape, or the like on a walking road surface b such as an outdoor sidewalk or indoor passage in a predetermined arrangement state. It is used to guide visually impaired people.
[0003]
In such a visually-impaired person guidance marker, there is one that uses 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, closed at both ends by sealing members f and f, and further spaced apart from the outer peripheral surface of the glass tube d by a predetermined distance. And a plurality of cuts g are formed. Then, in order to fix the marker body a using the anchor c, first, as shown in FIG. 5A, the glass tube d is inserted into the mounting hole h drilled in the walking road surface b, and is tilted sideways. Then, the glass tube d is cut to a predetermined length at the cut line g, and then, as shown in FIG. 5B, from above the glass tube d having a predetermined length inserted into the mounting hole h, With the connecting rod i made of a screw rod projecting downward on the bottom surface, the marker body a is struck downward with a tool such as a hammer, and the connecting rod i is struck to the bottom of the hole, thereby removing the glass tube d. Split the adhesive e into the mounting hole h. Then, as shown in FIG. 5C, the connecting rod i is fixed to the mounting hole h by the cured adhesive e to fix the marker main body a.
[0004]
[Problems to be solved by the invention]
In the anchor c as described above, since the glass tube d is long, it is easy to break during transportation due to impact, and it is troublesome and poor in workability because it must be cut to a predetermined length each time during its construction. Furthermore, there are various problems such as the adhesive e being hardened in the glass tube d if left for a long time during use without being used up to the end. Further, as shown in FIG. 5B, by attaching a connecting rod i of substantially the same diameter from above to a glass tube d of a predetermined length inserted in the mounting hole h, and hitting the connecting rod i 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 aggregates that increase the bonding strength of the adhesive e. There is a problem that it is not possible to achieve the above-mentioned function.
[0005]
An object of the present invention is to provide a marker for guiding a visually impaired person that can solve such a conventional problem.
[0006]
[Means for Solving the Problems]
The present invention relates to a marker body in which a connecting rod projects downward from a bottom surface, and an easy crush that is screwed into the lower end portion of the connecting rod and seals the adhesive filled therein by the screwing. A marker for guiding visually handicapped persons, comprising a bottomed cylindrical tube made of a sex material.
[0007]
Here, as the easily friable material, materials such as glass, ceramics, and plastics are proposed, and among them, glass can be used as the most suitable material.
[0008]
In this configuration, with the bottomed cylindrical tube screwed to the lower end of the connecting rod inserted into the mounting hole drilled in the walking road surface, the marker body is hit downward with an appropriate tool such as a hammer. By pressing, the connecting rod is pushed through the bottomed cylindrical tube to the bottom of the mounting hole, and the bottomed cylindrical tube is crushed so that the bottomed cylindrical tube is distributed substantially uniformly around the connecting rod. The adhesive diffuses in the mounting hole. Thus, when the adhesive is cured, the connecting rod is fixed to the mounting hole, and the marker body is fixed to the walking road surface. In addition, the fragmented pieces of the bottomed cylindrical tube dispersed substantially uniformly around the connecting rods effectively act as an aggregate that increases the bonding strength of the adhesive.
[0009]
Moreover, you may make it form a hardening | curing agent layer in the outer peripheral surface of the said bottomed cylindrical tube. In this case, the bottomed cylindrical tube is filled with an adhesive that is the main agent of the two-component mixed adhesive, and the curing agent of the main agent is applied to the outer peripheral surface of the bottomed cylindrical tube. And if a bottomed cylindrical tube is crushed as mentioned above, a main ingredient and a hardening | curing agent will be mixed and an adhesive agent can be hardened in a short time.
