Description

The present invention relates to a columnar sign that is installed on the road surface of a road or a parking lot for the purpose of marking, for example, the center line of a lane, lane guidance sign, traffic regulation guidance sign, or vehicle stopping position sign in a parking lot.

These types of pillar-shaped sign posts installed on centerlines etc. can be broken or damaged in vehicle collisions. For this reason, various inventions have been disclosed in which the pillar body and base are formed separately and then assembled in a disassembly manner, allowing pillar bodies damaged in vehicle collisions or deteriorated over time to be replaced.

For example, in Patent Document 1, the applicant has disclosed a flexible sign post that includes a cylindrical pole that is flexible enough to bend elastically when contacted by a vehicle, and a base that is installed on the road surface to support the pole upright when the pole is attached from above, with a protrusion that protrudes radially outward at the lower end of the pole, and the base has a support surface that supports the outer circumferential surface of the lower end of the pole, with the support surface being formed with a first recess into which the protrusion of the pole is inserted from above and a second recess that extends circumferentially from the first recess and into which the protrusion can enter, and an insert member is inserted into the first recess of the base when the protrusion of the pole has entered the second recess.

JP 2012-255273 A

Patent document 1 shows a configuration in which an insert member that prevents the pole from rotating is screwed to the base, and when attaching or detaching the pole, it is necessary to attach and remove this screw.

The present invention provides a pillar-shaped sign that allows easy installation and removal of the pillar.

In order to achieve the above object, the present invention has the following configuration.
In other words, the columnar sign of the present invention comprises a column, and a base onto which the column is attached from above and which supports the column upright, the base being formed with a first recess into which the protrusion of the column can be inserted from above, and a second recess extending circumferentially from the first recess into which the protrusion can enter, an insert member having an engaging claw portion is inserted into the first recess which connects to the second recess into which the protrusion has entered, the insert member being attached such that the engaging claw portion engages with the engaging portion of the base portion, and the base being formed with a hole portion leading from the outside to the engaging claw portion .

According to the columnar marker of the present invention, the protrusion of the column is inserted from above into the first recess of the base and enters the second recess extending in the circumferential direction, so that the protrusion is locked in the second recess and the column is prevented from moving upward. Also, since an insert member is inserted into the first recess of the base that connects to the second recess into which the protrusion has entered, the insert member prevents the protrusion that has entered the second recess from returning to the first recess, and the column can be stably attached without coming off the base.
Furthermore, since the plug-in member has an engaging claw portion and is attached by engaging the engaging claw portion with the engaging portion of the base portion, the operation of attaching the plug-in member can be easily performed.
Furthermore, the insertion member can be removed by releasing the engagement between the engaging claw portion and the engaging portion, so that the column can be easily removed from the base.

In addition, if a hole leading from the outside to the engaging claw is formed in the base and the engaging portion is provided at the end of this hole, the operation of releasing the engagement between the engaging portion and the engaging claw can be performed through the hole, which is preferable as it makes it easier to remove the column from the base.

In addition, if the engaging claw is arranged to protrude from the center of the column in a direction toward the outside, and the hole is drilled at an angle to the protruding direction of the engaging claw, the engaging claw is less likely to be released from its engagement due to pressure from foreign matter such as dirt that has entered the inside of the hole, and the insertion member can be stably attached to the base, which is preferable.

Furthermore, if the outer shape of the base when viewed in a plane is formed into a non-circular shape that is larger in the front-to-back direction than in the left-to-right direction, it is preferable to install the columnar sign with the front-to-back direction of the larger base facing the direction of vehicle travel, as this makes it less likely for the base to detach from the installation surface if an external force in the front-to-back direction is applied to the columnar sign, such as by a vehicle coming into contact with it.
Furthermore, if the hole is drilled along the left-right direction of the base, the columnar marker is installed with the front-rear direction of the base facing the vehicle's traveling direction, so that the hole is oriented perpendicular to the vehicle's traveling direction. By oriented in this way, when an external force in the front-rear direction is applied to the columnar marker due to contact with a vehicle, for example, foreign matter such as dirt that has entered the hole is less likely to move toward the engaging claw, and therefore the engaging claw is less likely to be released from engagement due to the engaging claw being pressed by the foreign matter, which is preferable.

The pillar-shaped sign of the present invention makes it easy to attach and detach the pillar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described with reference to the drawings.
In the drawings, F is a column-shaped marker, 1 is a column, 2 is a base, and 6 is an insert member.
The pillar-shaped marker F of this embodiment is formed by erecting a pillar 1 so as to protrude above a base 2 .
The columnar body 1 is attached from above the base 2 so as to be freely detachable.

The column 1 has a column portion 11 formed as a cylindrical hollow column, and a cap 12 is fixed to close the open upper end thereof.
In addition, a reflective sheet 14 having retroreflective properties that reflects irradiated light toward the light source is attached to the outer surface of the column 11. The reflective sheet 14 is wrapped around and attached to the outer surface of the column 11, and three reflective sheets 14 are arranged at intervals above and below the column 11 as shown in FIG.

The pillar body 1 is formed of a pillar portion 11 made of a thermoplastic polyurethane resin so that it has the flexibility to bend elastically when contacted by a vehicle, and then return to its original state. However, this is not limited to this, and soft polyolefins, elastomers, etc. can also be suitably used.
The cap 12 is also formed from the same thermoplastic polyurethane resin as the column portion 11, and is fixed to the column portion 11 by a method such as fusion or adhesion.

2 is a front view of the vicinity of the base 2 in FIG. 1, FIG. 3 is a side view of the vicinity of the base 2 in FIG. 1, and FIG. 4 is a plan view of FIG.
The base 2 has a rectangular shape formed of curved surfaces in a plan view, and is formed into an outer shape whose size in the front-to-rear direction is greater than its size in the left-to-right direction.
A mounting portion 20 for mounting the columnar body 1 is provided in the center of the base 2, and a strip-shaped reflective member R is wound around and attached to the outer wall of the mounting portion 20 which is formed in a flat, approximately truncated cone shape.

5 is a cross-sectional view taken along line AA in FIG. 4, and FIG. 6 is a view showing the state in which the columnar body 1 in FIG.
A base 4 is provided at the lower end of the column 1 .
Specifically, the base portion 4 is formed in a generally cylindrical shape separate from the column portion 11 and is fixed to the lower end of the column portion 11 .
In detail, the lower end of the column portion 11 formed in a cylindrical shape is inserted into an annular groove 41 formed concentrically on the upper surface of the base portion 4 and is fused and fixed.
A reinforcing tube 13 formed in a cylindrical shape with an outer diameter smaller than the inner diameter of the column 1 is fitted inside the hollow of the column 1 and fixed to the base 4. The lower end of the reinforcing tube 13 is inserted into an annular groove 42 formed concentrically inside annular groove 41 on the upper surface of the base 4, and is fused and fixed.

A support recess 21 is provided on the inside of the mounting portion 20 of the base 2, recessed in a shape corresponding to the base portion 4 at the lower end of the column 1, and the support recess 21 is formed so that the base portion 4 can be inserted freely.
The inner surface of the support recess 21 is formed into a support surface 23 capable of supporting the outer surface 43 of the inserted base portion 4, and the column 1 with the base portion 4 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.
The column 1 and the base 2 are fixed together using an insert member 6 .

7 shows the base 2 of FIG. 6, (a) is a plan view, (b) is a front view, FIG. 8 is a perspective view of the base 2 of FIG. 7, FIG. 9 is a front view showing the lower part of the pillar 1 of FIG. 6, FIG. 10 is a perspective view of FIG. 9, FIG. 11 is a cross-sectional view taken along line A-A of FIG. 9, and FIG. 14 shows the state before the lower end of the pillar 1 of FIG. 10 is inserted into the base 2 of FIG. 8.
As shown in FIGS. 9 to 11, a rectangular projection 45 that projects radially outward is formed on the outer circumferential surface 43 of the base portion 4 at the lower end of the column 1 .
The base portion 4 is formed with four projections 45 at equal intervals in the circumferential direction, and each projection 45 is formed to have the same shape.

A plate-shaped lid portion 44 that protrudes radially outward is formed on the outer circumferential surface 43 of the base portion 4 at the upper end of the base portion 4 .
The lid portion 44 has a flat underside all over and is umbrella-shaped all around the circumferential direction of the base portion 4, with the amount of outward protrusion being greater than that of the protrusion 45.

The umbrella-shaped lid portion 44 is formed with a notch 46 .
The cutout 46 is formed in a shape such that the protruding portion of the lid portion 44 is cut out in a rectangular shape from the edge side, and is formed at a position shifted in the circumferential direction from the formation position of the protrusion 45. Specifically, in a plan view, the cutout 46 is formed at a position shifted in the counterclockwise direction in the circumferential direction from the protrusion 45, and a side end 46a on the clockwise side of the cutout 46 is formed to be located directly above a side end 45a on the counterclockwise side of the protrusion 45.

As shown in FIGS. 7 and 8, the entire upper surface 24 of the mounting portion 20 of the base 2 is formed flat, and the support recess 21 is formed in the center of this upper surface 24 .
The support surface 23 of the support recess 21 is provided with a first recess 25 formed in a groove shape in the vertical direction from the upper surface 24 downward, and four first recesses 25 are formed at equal intervals around the circumferential direction of the support surface 23.
The groove width of each of the first recesses 25 is formed to correspond to the lateral size of the protrusion 45 of the base portion 4 of the column 1, and the groove recess size is formed to correspond to the protrusion size of the protrusion 45.
In other words, each first recess 25 is sized to allow the protrusions 45 to be inserted therein and to move in and out in the vertical direction, and is arranged so that when the base 4 of the column 1 is inserted into the support recess 21, each protrusion 45 formed on the lower end of the base 4 passes through each first recess 25. Each first recess 25 is formed to have the same shape, and is formed so that any of the four protrusions 45 can be inserted therein.

A groove-shaped second recess 26 is formed on the lower end of each of the first recesses 25 and extends circumferentially therefrom.
Each second recess 26 is formed so as to extend clockwise from each first recess 25 in a plan view.
As shown in Figures 8 and 14, each of the first recesses 25 and second recesses 26 is provided so as to form an approximately L-shaped groove in the support surface 23 by combining the first recess 25 extending in the vertical direction with the second recess 26 extending in the circumferential direction.
The size of the groove recess of each of the second recesses 26 is formed to be the same as the size of the protrusion of each of the protrusions 45, i.e., the same size as each of the first recesses 25, the size of the groove width in the vertical direction is formed to correspond to the vertical size of each of the protrusions 45, and the size of the groove in the horizontal direction is formed to correspond to the horizontal size of each of the protrusions 45.
In other words, after the base portion 4 of the cylinder 1 is inserted into the support recess 21, each of the second recesses 26 is formed so that when the cylinder 1 is rotated in a clockwise direction in a plan view, each of the protrusions 45 enters each of the first recesses 25 and is stored in each of the second recesses 26.

The mounting portion 20 of the base 2 is formed with a circular hole 27 that penetrates from a bottom surface 25a of the first recess 25 formed in a vertical groove shape to the outside.
One hole 27 is formed in the bottom surface 25 a of each first recess 25 , and a total of four holes 27 are provided in the mounting portion 20 .
As shown in FIG. 7A, the holes 27 are drilled and oriented so as to extend along the left-right direction of the base 2, which has an outer shape smaller than the front-rear direction in a plan view.
Each hole 27 is disposed so as to be inclined with respect to the recessed direction of the first recess 25 to which one opening portion is connected.
Specifically, each hole 27 is drilled at an angle toward the center of the support recess 21, and is arranged at an angle with respect to each of the first recesses 25 which are formed so as to be recessed radially outward from the support surface 23.

FIG. 15 is a diagram showing a state in which the lower end of the column 1 is inserted into the base 2 of FIG. 14, and FIG. 16 is a diagram showing a state in which the column 1 of FIG. 15 is rotated.
As shown in Figure 15, each protrusion 45 is inserted into each first recess 25, and the base portion 4 of the cylinder 1 is inserted into the support recess 21. Then, as shown in Figure 16, the cylinder 1 is rotated clockwise in a plan view, and each protrusion 45 enters each second recess 26.
In detail, the lateral size of the second recess 26 is formed to correspond to the lateral size of the protrusion 45, so that by rotating the cylinder 1 so that each of the protrusions 45 moves by its lateral size, each of the protrusions 45 enters the second recess 26 and is stored inside it.
By storing each protrusion 45 in the second recess 26 in this manner, the base 4 will not come out of the support recess 21 in the upward direction, and the column 1 will be attached to the base 2 .
Conversely, if the cylinder 1 in FIG. 16 is rotated counterclockwise in a plan view, each protrusion 45 will return and enter each of the first recesses 25, so that the cylinder 1 can be pulled upward and removed from the base 2.

Furthermore, as shown in Figure 15, when each protrusion 45 is inserted into each first recess 25 and the base portion 4 of the column 1 is inserted into the support recess 21, the lower surface of the lid portion 44 of the base portion 4 abuts against the upper surface 24 of the mounting portion 20 of the base 2, and the base 2 and the column 1 are formed so that the lid portion 44 covers the openings of each first recess 25 of the base 2.
When using the columnar marker F, if sand, debris, etc. enters the first recess 25 through the opening, this may damage the first recess 25 or the outer surface 43 of the base 4, or may hinder the removal of the column 1 from the base 2; however, the lid 44 covers the opening of each first recess 25, thereby preventing these problems from occurring.
Furthermore, since the lid portion 44 is formed around the entire circumference of the base portion 4 except for the position where the cutout portion 46 is formed, the gap between the support surface 23 of the base 2 and the outer peripheral surface 43 of the base portion 4 of the column 1 is not opened upward, thereby preventing sand, debris, etc. from entering this gap.
Furthermore, since the upper surface 24 of the base 2 and the lower surface of the lid portion 44 are each formed flat over the entire surface, there is no problem in that contact between the lid portion 44 and the upper surface 24 of the base 2 becomes an obstacle when the cylinder 1 inserted into the base 2 is rotated.

As shown in Figure 16, when the cylinder 1 is rotated and each protrusion 45 is stored in each second recess 26 of the base 2, the notch 46 formed in the lid 44 of the cylinder 1 is positioned above the first recess 25 of the base 2.
Furthermore, since the cutout portion 46 is formed to have the same lateral dimension as the protrusion 45, the first recess 25, which is formed with a lateral width and recess size corresponding to the protrusion 45, opens upward through the cutout portion 46 located directly above.

12 shows the insertion member 6 of FIG. 6, where (a) is a plan view, (b) is a front view, and (c) is a right side view, and FIG. 13 is a cross-sectional view taken along line AA of FIG.
The insertion member 6 has a pin body 61 formed in a generally rectangular shape that is long in the vertical direction, and a plate-shaped locking projection 62 that projects forward from the upper end of a front surface 61 a of the pin body 61 .
The width of the locking projection 62 is set to the same size as the width of the pin body 61 .

An engagement claw portion 67 is formed near the center of the pin body 61 of the insertion member 6 so as to be disposed inside a substantially rectangular hole portion 66 extending from the front surface 61a to the rear surface 61b. The engagement claw portion 67 has a substantially rectangular plate-like base portion 67a that is thinner than the pin body 61, and the lower end of the base portion 67a is connected to the pin body 61, and a claw-shaped portion 67b that protrudes forward is formed at the upper portion of the base portion 67a.
As shown in Figure 12, the engagement claw portion 67 has a base portion 67a bent forward to form a roughly L-shaped claw portion 67b, and as shown in Figure 13, the claw portion 67b is formed so as to protrude forward from the front surface 61a of the pin body 61.
The engaging claw portion 67 is configured so that when force is applied to the claw-shaped portion 67b from the front side, the base 67a bends and deforms, and the entire engaging claw portion 67 including the claw-shaped portion 67b is stored inside the hole portion 66, and when the force from the front side is removed, it undergoes elastic deformation to return to its original state.

The pin body 61 has a vertical size, horizontal width, and thickness that correspond to the vertical groove size, groove width, and groove depression size of the first recess 25 of the base 2, respectively, and the front surface 61a of the pin body 61 is formed into a curved shape that corresponds to the bottom surface 25a of the groove of the first recess 25.
That is, the pin body 61 is formed to a size that can be housed inside the first recess 25 .
In addition, the rear surface 61b of the pin body 61 is formed into a curved shape corresponding to the support surface 23 of the base 2, and is configured so that when the pin body 61 is stored in the first recess 25, the rear surface 61b of the pin body 61 does not protrude into the circularly recessed support recess 21.
In addition, the lower part of the first recess 25 is formed as a through hole that penetrates the bottom surface of the support recess 21 and reaches the lower outside of the base 2, and is configured so that when the pin body 61 is stored in the first recess 25, the lower end of the pin body 61 is inserted into the hole-shaped portion at the lower part of the first recess 25.

As shown in Figure 16, the columnar marker 1 shown in Figure 1 is constructed by inserting and attaching the insertion member 6 from above into the inside of the first recess 25, which is located directly below the cutout portion 46 and opens upward.
By attaching the insert member 6 into the first recess 25, the protrusion 45 is engaged with the insert member 6, restricting the rotation of the cylinder 1 such that the protrusion 45 returns to the first recess 25, and the cylinder 1 is stably attached to the base 2.
In addition, the insertion member 6 stored inside the first recess 25 blocks the opening of the first recess 25 located directly below the cutout portion 46, thereby preventing sand, debris, etc. from entering the first recess 25.
Then, by removing the insertion member 6 from the first recess 25, the cylinder 1 can be rotated in the reverse direction, and each protrusion 45 can be inserted from the second recess 26 into the first recess 25, allowing the cylinder 1 to be removed from the base 2.

The insertion member 6 inserted into the first recess 25 is attached by engaging the engaging claw portion 67 with the base 2 .
FIG. 17 is a vertical cross-sectional view of the vicinity of the insert member 6 of FIG.
The insertion member 6 is formed so that when inserted into the first recess 25 , the lower surface of the protruding locking protrusion 62 comes into contact with the upper surface 24 of the base 2 for attachment.
The insertion member 6 is engaged by inserting the protruding portion of the claw-shaped portion 67b of the engaging claw portion 67 into the inside of the hole portion 27 that opens into the bottom surface 25a of the first recess 25. That is, the inner end of the hole portion 27 functions as an engaging portion that engages the engaging claw portion 67.
By engaging the engaging claw portion 67 in this manner to attach the insertion member 6 to the base 2, problems such as the insertion member 6 falling out of the base 2 while the column-shaped sign F is in use are less likely to occur.
Furthermore, by inserting the insertion member 6 into the first recess 25, the claw-like portions 67b engage with the holes 27, making it easier to attach the insertion member 6.
When removing the plug-in member 6 attached to the base 2, a rod-shaped body is inserted from the outside into the inside of the hole portion 27 and the tip of the rod-shaped body is used to press the protruding portion of the claw-shaped portion 67b, whereby the engagement between the claw-shaped portion 67b and the hole portion 27 is easily released and the plug-in member 6 can be pulled out upward.

The insertion member 6 shown in FIG. 1 and FIG. 17 is stored inside the first recess 25 so as to fit into it, and the engagement claw portion 67 of the insertion member 6 is arranged so that the claw-shaped portion 67b protrudes in the direction in which the first recess 25 is recessed. In other words, the protruding direction of the claw-shaped portion 67b is arranged at an angle to the direction of the hole portion 27, which is formed at an angle to the direction in which the first recess is recessed. By forming the hole portion 27 in this manner, when an external force is applied to the column-shaped sign F due to vehicle contact or the like, and a foreign object such as dirt that has entered the inside of the hole portion 27 moves along the hole portion 27 and contacts the claw-shaped portion 67b, a force is applied in a direction inclined to the protruding direction of the claw-shaped portion 67b, and the engagement of the engagement claw portion due to contact with the foreign object is less likely to be released. With the above configuration, the insertion member can be stably attached to the base.

The columnar marker F is provided so that the column 1 has flexibility, and assumes a situation in which a vehicle or the like may come into contact with the column 1. For this reason, when the columnar marker F is installed near a road, the base 2, which is formed to be larger than the left-right dimension, is arranged so that the front-rear direction is aligned with the direction of travel of the vehicle, so that when an external force in the front-rear direction is applied to the columnar marker F due to contact with a vehicle or the like, the base 2 is unlikely to come off the installation surface, such as the road surface.
In addition, by arranging the columnar marker F so that the front-rear direction of the base 2 is aligned with the vehicle's traveling direction as described above, the holes 27 formed along the left-right direction are arranged perpendicular to the vehicle's traveling direction. By arranging the holes 27 in this manner, when an external force is applied to the columnar marker in the front-rear direction, which is the traveling direction of the vehicle, due to contact with the vehicle, etc., foreign matter such as dirt that has entered the inside of the hole 27 is made less likely to move toward the engaging claws 67 arranged in the left-right direction, so that the engagement is less likely to be released due to the foreign matter pressing the engaging claws 27. In other words, the insertion member 6 is prevented from coming off the base 2 due to contact with the vehicle, etc., and the attachment of the column 1 to the base 2 is more stable.

The pillar-shaped marker F according to the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present invention.
For example, the columnar marker F according to the present invention has the column portion 11 of the column 1 formed in a cylindrical shape, but is not limited to this. A part of the column 1 may be made flat to make the display on its surface easier to see, and a plurality of columnar markers F standing at intervals may be connected by a beam-shaped member detachably attached to the column 1.
