JP2000226818A - Marker rivet for pavement - Google Patents

Abstract

PROBLEM TO BE SOLVED: To freely form a marker for pedestrians on an existing pavement. SOLUTION: A rivet main body A is so constituted that an appropriate number of locking part pieces 6 lined along a peripheral edge of an engaging hole 2 are protruded from a lower surface of a marker bedrock 1 provided with the engaging hole 2. A locking edge 7 for bringing in pressure contact with a wall surface 11' in an attaching hole 11 formed on a pavement is protruded from an outer surface of a lower part of the locking part pieces 6 of the rivet main body A. Further, a head part piece 4 locked with the rivet main body A by engaging with the engaging hole 2 is provided on a top end of a fixing rod 3 compulsorily inserted on an inner side of a lower part of the locking part pieces 6 through the engaging hole 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign installed on a pavement (an artificial place provided for walking or coming of people such as a road or a platform of a station) to assist a blind person to walk. It is about tacks.

[0002]

2. Description of the Related Art Generally, a concrete plate having an uneven pattern on its upper surface so as to be seen in a station yard or a sidewalk is installed at a specific location to assist a blind person in walking.

[0003]

In the prior art, a sign is formed by a concrete plate of a specific size or shape. Therefore, in order to install a "sign" on an existing pavement, at least a part of the pavement is required. In this case, the concrete slab must be laid and the work is complicated, and depending on the location (for example, a staircase in a station yard), laying may not be possible.

[0004] In view of such circumstances, the present invention has been devised for the purpose of providing an article suitable for placing a "sign" on a pavement.

[0005]

An appropriate number of locking pieces are arranged on the lower surface of the sign base provided with the engaging holes and are arranged along the periphery of the engaging holes to form a main body of a tack. A locking edge that presses against a wall surface of a mounting hole formed in a pavement road is protruded from a lower outer surface of the locking portion piece mainly composed of the studs, and is forced inside the lower portion of the locking portion piece through the engagement hole. A head piece is provided at the upper end of the fixed rod to be inserted so as to be engaged with the engagement hole and locked to the tack.

[0006]

A mounting hole is provided in a pavement, a locking piece is engaged with the mounting hole, the mounting hole is closed with a sign board, and a tack member is assembled on the pavement, and a fixed rod is attached to the sign board. When the head piece of the fixed rod is hit with a tool such as a hammer, the fixed rod descends and is forcibly inserted into the lower inside of the locking piece. As a result, the locking piece is expanded, the locking edge provided on the lower outer surface thereof is pressed (inserted) into the wall surface of the mounting hole, and the head piece is engaged with the engaging hole. They are joined together, locked by the tacks, and fixed to the pavement.

[0007] In this fixed state, the sign base protrudes from the pavement road surface, and irregularities are formed on a part of the pavement road surface to become a "sign".

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view showing an embodiment of a pavement marker stud according to the present invention. FIG. 1 is a sectional view showing a used state, and FIG. 3 is a perspective view mainly of the tack.

In the drawing, reference numeral 1 denotes a sign base mainly composed of tacks A. The sign base 1 is provided with an engaging hole 2 having a circular cross section at the center of the truncated cone, and the engaging hole 2 is surrounded on the upper surface. A groove 10 for preventing slippage is provided. The engaging hole 2 engages with the upper portion 2a having a large diameter and the lower portion 2b having a small diameter so as to engage with the bottom edge 5 of the upper portion 2a. It is.

On the lower surface of the sign base 1, engaging portions 6, 6, 6, 6 are projected so as to be arranged along the peripheral edge of the engaging hole 2, thereby forming the tack main body A. The lower portion of the locking piece 6 is made thicker, and a triangular locking edge 7 is projected on the outer surface and a pressure receiving edge 8 is projected on the inner surface.

The locking piece 6 communicates with the engaging hole 2 on the lower surface of the sign base 1 and projects from a cylindrical body which is the same as the axis of the engaging hole 2. The cylindrical body formed by providing slits 9, 9, 9, 9 in the opening on the lower end side at equal intervals is constituted by a branch piece.

The fixed rod 3 is provided with a circular piece-shaped head piece 4 corresponding to the upper part 2a of the engaging hole 2 at the upper end of an upper part 3a having a larger diameter than the lower part 3b. The outer diameter is made larger by the diameter of the space formed by surrounding the pressure receiving edge 8 below the locking piece 6, and the lower portion 3 b is inserted into the pressure receiving edge 8 so as to be engaged. The stop piece 6 is expanded and plastically deformed.

Thus, a mounting hole 11 is formed in the pavement road, and the locking portion piece 6 is inserted into the mounting hole 11 so as to close the mounting hole 11 with the sign board 1 so as to pave the tack main body A. When the fixed rod 3 is inserted on the inside of the locking piece 6 through the engagement hole 2 and the head piece 4 of the fixed rod 3 is hit with a hammer or the like, the fixed rod 3 is lowered and its tip is disposed. Lower 2
b is forcibly inserted between the pressure receiving edges 8, the locking piece 6 expands, and the locking edge 7 provided on the lower outer surface is pressed (press-fitted) into the wall surface 11 ′ of the mounting hole 11, thereby paving the pavement. A "sign" is formed on the road.

[0014] Various types of "signs" can be provided by arranging a proper number of them at appropriate places on the pavement.

Since the fixing rod 3 is locked (vertically) by the tack main body 1, there is no problem even if the mounting hole 11 is formed deeper than necessary.

The tack main body A and the fixing rod 3 are made of stainless steel, but may be made of other metal (synthetic resin in some cases). is there.

The surface (upper surface) of the sign board 1 to the head piece 4
Is colored with an appropriate color, thereby providing a more effective marker for amblyopia.

For example, it is a matter of course that the article of the present invention can be applied to a so-called tile laid in a building as a pavement path.

[0019]

The present invention has the configuration described above,
A sign for pedestrians can be freely formed on an existing pavement, and is not bulky, and is suitable for transportation and storage.

Claims (1)

[Claims] 1. A main body of a tack is formed by projecting an appropriate number of locking portions along the periphery of the engaging hole on a lower surface of a sign base provided with an engaging hole. At the lower outer surface of the locking piece, a locking edge for pressing against the wall surface of the mounting hole formed on the pavement is protruded, and forcibly inserted into the lower inside of the locking piece through the engaging hole. A pavement road marking stud provided with a head piece at the upper end of a fixed rod to be engaged with the engagement hole and locked to the stud main body.
