Claims (3)

1. A base that is placed between the sign and the mounting surface and is fixed to the mounting surface by adhesive, It comprises a base whose lower surface serves as an adhesive surface, and a threaded portion formed above the lower surface, It is provided so as to be detachably attached to the indicator body via the screw portion, The base is formed of a metal material , A base characterized in that one screw portion is formed on the base, and a screw member is formed separately from the indicator body, and the screw member is screwed onto the one screw portion so that the base, which is made of a metal material, can be detachably attached to the indicator body which is formed separately .
2. The base according to claim 1 , characterized in that the base portion is formed to be smaller than the lower surface of the marker.
3. The marker according to any one of claims 1 to 2, characterized in that the base is attached via the screw portion.

Description

This invention relates to a base for adhesively fixing a marker to a place where vehicles travel, such as a road or parking lot. Markings installed on roads and in parking lots to indicate lane center lines, lane guidance markings, and traffic control markings are fixed to their installation locations using methods appropriate to the location and purpose. For example, methods using anchor bolts or adhesives have been conventionally used, and various inventions have been proposed for methods using adhesives. For example, Patent Document 1 proposes a method for attaching a road marking to a road surface by adhesive, comprising a base portion having a recessed portion with an opening in its surface, and a main body portion projecting above the base portion. The mounting portion is formed in the center of the base portion and is designed to detachably attach a first anchor bolt for fixing the base portion by screwing it into an anchor nut embedded and fixed in the road surface. The method is characterized by attaching a bottom plate material, formed to close the opening in the recessed portion, to the lower surface of the base portion via the mounting portion, and then adhering the bottom plate material to the road surface with an adhesive applied to its bottom surface. Japanese Patent Publication No. 2010-84452 This is a front view showing one embodiment of the marker according to the present invention.This is a bottom view of Figure 1.This figure shows the column and base separated from each other, as shown in Figure 1.This figure shows the base and pedestal separated from Figure 3.Figure 4 is a front view showing the base.Figure 5 is a plan view.This is a cross-sectional view taken along line A-A in Figure 6, showing the longitudinal section of the base.This figure shows the base of Figure 7 in place.This figure shows the base of the sign placed on the pedestal shown in Figure 8.This figure shows the base attached to the pedestal shown in Figure 9. Embodiments of the present invention will be specifically described with reference to the drawings. In the drawing, 1 is a sign. The sign body 1 shown in Figure 1 comprises a column 10 and a base 2, and is formed by erecting the column 10 so as to protrude above the base 2. A base 5 is attached to the underside of the base 2 of the sign body 1. The column 10 comprises a column portion 11 formed from a cylindrical hollow columnar body, and a cap 12 is fixed to close its open upper end. Furthermore, a reflective sheet 14 having retroreflective properties that reflects irradiated light back towards the light source is attached to the outer surface of the column portion 11. The reflective sheet 14 is wrapped around and attached to the outer surface of the column portion 11, and as shown in Figure 1, three reflective sheets 14 are arranged on the column portion 11 with gaps between them vertically. The column 10 is formed from thermoplastic polyurethane resin so that it has flexibility to bend elastically due to contact with a vehicle, etc., and then return to its original state. However, it is not limited to this, and soft polyolefins, elastomers, etc. can be suitably used. Furthermore, the cap 12 is also made of the same thermoplastic polyurethane resin as the column portion 11 and is fixed to the column portion 11 by methods such as fusion or adhesive bonding. Figure 2 is a bottom view of Figure 1. The base 2 has a rectangular shape when viewed from below, with the entire shape composed of curves, and its size in the front-to-back direction is larger than that in the left-to-right direction. The base 2 is made of acrylonitrile-styrene-acrylate resin (ASA resin), which is harder than the column 10, but is not limited to this, and may be formed by selecting or combining synthetic resins other than ASA resin. The column 10 is detachably attached to the base 2. Furthermore, a base 5 having a disc-shaped base 51 is detachably attached to the lower surface of the base 2. Figure 3 shows the column section 11 and base 2 separated from each other as shown in Figure 1. A base portion 15 is provided at the lower end of the column 10. Specifically, the base portion 15 is formed in a substantially cylindrical shape, separate from the column portion 11, and is fixed to the lower end of the column portion 11. The upper part of the base 2 is provided with a support recess 21 that is recessed in a shape corresponding to the base portion 15, and the support recess 21 is formed so that the base portion 15 can be inserted into it freely. The inner circumferential surface of the support recess 21 is formed as a support surface 23 capable of supporting the outer circumferential surface 15a of the inserted base portion 15, and the column 10, with the base portion 15 inserted into the support recess 21 of the base 2, is erected with its lower end supported by the support surface 23 of the base 2. Furthermore, the outer circumferential surface 15a of the base portion 15 has multiple rectang
