DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heart building marker formed as a projection on a floor on which a carpet is laid for guiding a visually impaired person or the like.

[0002]

2. Description of the Related Art Conventionally, in order to guide a visually impaired person,
Among the heart-building markers attached as protrusions on the floor, those that are attached to the floor on which the carpet is laid are used as methods of attachment to the carpet, such as a screw fastening type shown in FIG. 17, a caulking fastening type shown in FIG. Various attachment methods have been proposed, such as a hook-stop type shown in FIG.

[0003] The screwing type shown in FIG. 17 is such that the carpet C is sandwiched between a marker body 911 which becomes a projection on the carpet C and a receiving tool 951, and in this state, the carpet C is provided from the lower surface side of the receiving tool 951. In this method, a screw 961 is screwed into a screw hole 921 on the lower surface of the marker body 911 via the hole H.

In the caulking type shown in FIG. 18, a leg 922 penetrating a hole H provided in a carpet C is formed on the lower surface of a marker body 912, and the leg 922 is formed on the back side of the carpet C. In this method, the marker body 912 is attached to the carpet C by deforming the lower end portion 923 so as to expand.

The hook stopper type shown in FIG.
The shaft portion 923 provided on the upper surface of the shaft 53 is inserted into the hollow portion 973 in the marker body 913 through the hole H provided in the carpet C, and is engaged with the engaging portion 933 formed at the tip of the shaft portion 923. This is a method in which the marker body 913 is attached to the carpet C by engaging with an engaged portion 983 formed on a peripheral portion of the hollow portion 973.

[0006]

However, in the conventional screwing type, the marker body 911 and the receiving member 951 must be positioned above and below the hole H of the carpet C, and the screw 961 must be inserted from the lower surface side. Therefore, the mounting operation is troublesome, and it is necessary to use screws 961 having different lengths depending on the thickness of the carpet C to be mounted. Furthermore, if a pedestrian or the like steps many times after the construction, the screw 961 is easily loosened and easily detached.

In addition, the caulking-stopping type requires a dedicated mounting device for deforming the lower end portion 932 of the leg portion 922 so as to be widened, and the mounting operation is difficult and requires skill, so that the workability is very poor. Was.

[0008] The hook-stop type is a
When the marker body 3 is fitted into the shaft portion 923 of the receiving member 953, the marker body 913 is easily displaced from the shaft portion 923 and is difficult to attach. Since the thickness of the central part of the main body 913 is reduced, the strength is weak, and there is a possibility that the main body 913 will be broken if it is stepped on many times after construction.

Further, when the carpet C is repeatedly stepped on by a pedestrian or the like after the construction and the elasticity of the carpet C is reduced, and the thickness of the carpet C is reduced, the heart-building marker according to the above-mentioned conventional mounting method becomes the marker body 911, 912,
913, a receiving tool 951, and a lower end portion 93 of the leg 922.
2. Since the coupling distance with the receiving tool 953 is constant, it may protrude more than necessary on the carpet C, and may be in an inappropriate state as a projection for guiding a visually impaired person or the like.

The present invention has been made in view of the above problems, and has as its object to provide a heart building marker that can be easily attached to a carpet.
