Description

The present invention relates to a marker column.

In spaces with traffic such as roads and parking lots, multiple areas with different traffic divisions coexist. For example, sidewalks and driveways, outbound and inbound routes, and parallel lanes (traffic lanes) are areas with different traffic divisions.

In order to ensure traffic safety and smoothness, it is necessary to physically or visually divide areas with different traffic divisions. As one of the methods for that purpose, a sign post in which a cylindrical post is erected on a pedestal fixed to the ground is widely used. The signpost can physically and visually divide areas having different traffic divisions (see, for example, Patent Document 1, FIG. 10 and the like).

Sign pillars are used in a wide range of fields, such as median strips, lane strips, guidance to ETCs, vehicle entry restraints, parking / stopping prohibitions, pedestrian road separations, and bicycle pedestrian separations.

One of the challenges that arises when using signposts is dealing with areas where the ground is sloping. Surprisingly, there are many places where the ground is sloped, roads have a water gradient for drainage, and slopes and slopes have slopes in the first place. Since the post is fixed at a right angle to the pedestal, if the ground where the sign pillar is installed is inclined, the post will also be inclined. If the post is to be placed vertically, it is necessary to set the mounting angle of the post with respect to the pedestal according to the tilt angle of the installation location of the sign post.

Patent Document 2 discloses a sign column integrated with a pedestal (1) in a state where a post (pole body (2)) is tilted. The integration is performed by inclining and holding the pole body (2) in the mounting hole of the pedestal (1) and pouring a polyurethane material into the mounting hole to solidify it. At this time, the inclination angle of the pole body (2) is determined according to the inclination angle of the road on which the pole body (2) is installed (see paragraph [0014] of Document 2, FIG. 1).

Patent Document 3 discloses a sign column capable of varying the angle of the post with respect to the pedestal. In this sign column, a spherical portion (8) is provided on the upper portion of the pedestal (base (4)) so that the post (tube portion (9)) can be fixed at any position of the spherical portion (8). By adjusting the fixed position with respect to the spherical surface portion (8), the angle of the pipe portion (9) can be freely set (see paragraph [0014] of Document 3).

As a structure for fixing the pipe portion (9) to the spherical portion (8), Patent Document 1 describes a penetrating shaft (13) penetrating the pipe portion (9) and a cam lever attached to the upper end of the penetrating shaft (13). It is combined with the locking mechanism according to (15) (see paragraphs [0015] and [0016] in Document 3).

The penetrating shaft (13) is prevented from coming off the lower end side by the lower surface of the base portion (4), and the upper end side is penetrated by the lid portion (11) covered with the pipe portion (9). The cam lever (15) has a lever portion (15a) and a cam portion (15b), and gives the cam portion (15b) a cam profile that varies the distance to the lid portion (11). The cam lever (15) as a locking mechanism rotates the cam portion (15b) by operating the lever portion (15a), thereby pulling up the through shaft (13) to control locking and unlocking, and the spherical surface portion (15a). The fixing of the pipe portion (9) to 8) and the release thereof are realized.

According to the sign columns described in Patent Documents 2 and 3, the posts can be arranged vertically even if the installation location is inclined. In the case of the signpost described in Patent Document 2, a signpost having an inclination angle of the post corresponding to the inclination of the installation location is prepared in advance. In the case of the sign post described in Patent Document 3, after installation, the angle of the post is adjusted according to the inclination of the installation location.

However, it is rare that the signposts are installed independently, and it is common that a number of signposts are arranged at regular intervals along the traffic division. At this time, it is not uncommon for the location of the signpost to continue to incline. Therefore, according to Patent Document 2, it is necessary to prepare a large number of sign columns whose posts are tilted according to the tilt of the installation location. According to Patent Document 3, it is necessary to perform a lot of work to adjust the angle of the post according to the inclination of the installation place.

However, in any of the sign columns of Patent Documents 2 and 3, the inclination angle of the post must be set manually for each sign column. Therefore, as the number of sign columns that require the angle setting of the post increases, the work load increases. Improvement measures are required to reduce the work load.

The sign post includes a pedestal fixed to the installation location, a post, and a fixture for fixing the post to the pedestal, and the pedestal is a mounting wall that fits into the lower end of the post inserted from the upper surface side. And a pair of fixing holes, each arranged on a horizon and horizontally penetrating at two locations on the mounting wall, the post is on a reference line inclined with respect to a line orthogonal to the axis of the post. The post is provided with a pair of through holes that are respectively positioned in the pair of fixing holes in a state of being fitted to the mounting wall, and the fixing tool is inserted into the pair of the fixing holes and the through holes. The post is fixed to the pedestal.

It is possible to easily manufacture a sign post whose post is tilted according to the tilt of the installation location, and it is possible to reduce the work load.

An embodiment of the sign column will be described with reference to the drawings. The signpost is used in various scenes such as median strip, lane separation zone, guidance to ETC, vehicle entry restraint, parking / stop prohibition, pedestrian road separation, and bicycle pedestrian separation. For this reason, there are various places where sign pillars are installed, such as the ground, the road surface, and the floor surface of buildings. In this embodiment, an example of installation on a road provided on a bridge is shown.

As shown in FIG. 1, a road 13 having one facing lane with sidewalks 12 arranged on both sides is arranged on the bridge 11, and a median strip 15 is provided between the lanes 14. The median strip 15 is inclined downward to the left when viewed from the direction shown in FIG. 1, and sign columns 101 are installed at regular intervals in the inclined portion. The median strip 15 is an installation place for fixing the sign column 101.

An embodiment of the sign column 101 will be described with reference to FIGS. 1 to 7 (A) and 7 (B).

As shown in FIGS. 1 to 4, the sign column 101 has a structure in which a pedestal 111 and a cylindrical post 121 are combined and both are fixed by a pair of fixtures 131. The pedestal 111 and the post 121 are molded from a resin such as polyurethane elastomer. Fixture 131 is a metal shoulder bolt.

The pedestal 111 is composed of a base 112 and a boss 113, and the boss 113 is integrally provided on the upper surface BU of the base 112 which is square when viewed from a plane.

The base 112 is a portion fixed to the installation location by adhesion, and the lower surface BB is made flat so as to enable adhesion to the installation location.

The boss 113 is a portion for connecting the post 121 to the base 112, and is provided with a mounting groove 114 on the upper surface for inserting the lower end portion 121L (see FIG. 4) of the post 121. The mounting groove 114 is provided with a cylindrical first wall W1 on the outer peripheral side and a cylindrical second wall W2 having a diameter smaller than that of the first wall W1 on the inner peripheral side. The first wall W1 and the second wall W2 are perpendicular to the lower surface BB of the base 112 and are arranged concentrically with each other. The bottom surface B of the mounting groove 114 is parallel to the bottom surface BB of the base 112.

The groove width of the mounting groove 114, that is, the distance between the first wall W1 and the second wall W2, has a size suitable for the cylindrical post 121, whereby the post 121 to the mounting groove 114 has a size suitable for the cylindrical post 121. It can be inserted. The first wall W1 and the second wall W2 form a mounting wall W that fits with the post 121.

In order to obtain the first wall W1 and the second wall W2, the boss 113 is provided with a first protrusion 114A on the outer peripheral side of the mounting groove 114 and a second protrusion 114B on the inner peripheral side. The first wall W1 is the inner peripheral surface of the first protrusion 114A, and the second wall W2 is the outer peripheral surface of the second protrusion 114B.

The post 121 has a cap 123 on the upper end of the hollow main body 122, and a three-row reflective sheet 124 is fixedly wound around the upper portion of the outer peripheral surface. The substance of the post 121 is a cylindrical body 122.

In this embodiment, the concept of a shaft is set on the pedestal 111 and the post 121. The axis of the pedestal 111 is referred to as the axis O1, and the axis of the post 121 is referred to as the axis O2 (see FIGS. 2 and 3).

The axis O1 of the pedestal 111 is a straight line orthogonal to the horizontal plane including the lower surface BB of the base 112 and passing through the center of the mounting groove 114.

The axis O2 of the post 121 is a straight line extending in the extending direction of the main body 122 and passing through the center of the horizontal cross section of the main body 122 standing vertically.

The boss 113 is provided with a pair of fixing holes 115. These fixing holes 115 are provided side by side on the horizontal line HL1 orthogonal to the axis O1 of the pedestal (see FIG. 2). The fixing hole 115 horizontally penetrates the mounting wall W so as to straddle the two regions A1 and A2 divided by the vertical surface VL1 including the axis O1 of the pedestal 111 and penetrate the mounting groove 114. It penetrates the pedestal 111 (see FIG. 3).

In the present embodiment, since the mounting wall W has the first wall W1 and the second wall W2, the fixing holes 115 have two places of the first wall W1 and two places of the second wall W2. Penetrates. The two places in this case mean that there is one place in each of the two regions A1 and A2 divided by the vertical plane VL1.

A pair of through holes 125 are provided in the lower end portion 121L of the post 121 (see FIG. 4). These through holes 125 are arranged at positions corresponding to the pair of fixing holes 115 in a state where the post 121 is inserted into the mounting groove 114.

As shown in FIG. 3, the pair of fixatives 131 (shoulder bolts) are provided with a threaded portion 134 at the tip of the shoulder 133 continuous from the head 132. The threaded portion 134 has a smaller diameter than the shoulder 133.

These fixtures 131 penetrate the fixing hole 115 and the through hole 125, and fix the pedestal 111 and the post 121 in a skewered manner.

The inside of the fixing hole 115 is formed in a stepped shape having a two-step step portion according to the shape of the head 132, the shoulder 133, and the screw portion 134 of the fixing tool 131 (indicated by a hidden line in FIG. 3). ). The inner diameter of the fixing hole 115 is reduced with the step portion as a boundary. When the fixture 131 was inserted into the fixing hole 115, the head 132 hit the first step, the shoulder 133 hit the second step, and the threaded 134 had the smallest diameter in the fixing hole 115. It is press-fitted into the part. As a result, the fixative 131 is positioned and fixed in the fixing hole 115.

At this time, the first step portion to which the head 132 abuts, the second step portion to which the shoulder 133 abuts, and the small diameter portion into which the screw portion 134 is press-fitted are all provided in the first protrusion 114A. The fixing hole 115 provided in the second protrusion 114B and penetrating the second wall W2 is set to a diameter that only allows the inserted fixing tool 131 to pass through and does not press-fit the fixing tool 131.

The sign column 101 of the present embodiment allows the post 121 to be arranged vertically even if it is installed in the inclined median strip 15 (see FIG. 1). As a mechanism for that purpose, the sign column 101 does not arrange a pair of through holes 125 provided in the lower end portion 121L of the post 121 on the horizontal line HL2 orthogonal to the axis O2 of the post 121, but with respect to the horizontal line HL2. It is arranged on the inclined reference line L2 (see FIG. 4). explain in detail.

The first thing you need to know in order to arrange the post 121 vertically is the tilt angle of the installation location where the sign post 101 is installed. In the case of this embodiment, it is necessary to know the inclination angle of the median strip 15 on which the sign column 101 is installed. Therefore, the inclination angle of the median strip 15 is grasped from the design drawing of the bridge 11 or by actual measurement.

Here, it is assumed that the inclination angle of the median strip 15 is α degrees, that is, it is inclined by an angle α with respect to the horizontal plane.

Next, in order to determine the arrangement position of the pair of through holes 125, the reference line L2 is virtualized. The reference line L2 is a virtual line inclined by the same angle α as the inclination angle of the median strip 15 with respect to the horizontal line HL2 orthogonal to the axis O2 of the post 121.

If the reference line L2 is virtualized, a pair of through holes 125 are formed on the reference line L2 (see FIG. 4). This is the structure for vertically arranging the post 121.

When the positions of the pair of through holes 125 are determined in this way, the lower end portion 121L of the post 121 is inserted into the mounting groove 114 of the pedestal 111, and the pair of through holes 125 are inserted into the pair of fixing holes 115 positioned on the horizontal line HL1. When aligned, the post 121 is tilted by an angle α with respect to the axis O1 of the pedestal 111 (see FIG. 2). If the post 121 is fixed with the fixative 131 in this state, the post 121 is maintained at that angle.

When the completed sign column 101 is installed in the median strip 15, the pedestal 111 is tilted along the inclination of the installation location, and the post 121 is vertically arranged (see FIG. 1).

The basic structure for vertically arranging the post 121 is as described above. The marker column 101 of the present embodiment also has a structure of an appropriately set groove width of the mounting groove 114 as a structure required because such a basic structure is adopted.

In order to explain this "groove width of the mounting groove 114 appropriately set", in this embodiment, the concept of the occupied area of the post 121 in the mounting groove 114 is introduced. The occupied area means the area occupied by the post 121 in the horizontal plane in the mounting groove 114 in which the horizontally installed pedestal 111 is viewed in a plan view.

This will be described in detail with reference to FIGS. 5 (A) and 5 (B) and FIGS. 6 (A)-(C). In FIGS. 5A and 5B, the post 121 is schematically shown in a pillar shape for the sake of simplicity. HL indicates the height position of the bottom surface B of the mounting groove 114, and HH indicates the height position of the frontage of the mounting groove 114. FIG. 5 (A) shows the occupied area when the post 121 is oriented vertically by hatching, and FIG. 5 (B) shows the occupied area when the post 121 is tilted from the vertical direction by hatching. There is.

As shown in FIG. 5A, the occupied area of the post 121 when the post 121 is oriented vertically, that is, the area occupied by the post 121 in the horizontal plane in the mounting groove 114 is the occupied area E1 at the height HL. At height HH, the occupied area is E2. At this time, the occupied areas E1 and E2 at the two locations are the same, and they completely overlap each other in the vertical plane. Here, the width of the two occupied areas E1 and E2 in a plan view is defined as the width Wa.

As shown in FIG. 5B, when the post 121 is tilted from the vertical direction, the occupied area of the post 121 becomes the occupied area E3 at the height HL and the occupied area E4 at the height HH. At this time, the occupied areas E3 and E4 at the two locations are the same, but each has a shape that extends long in the inclined direction, and moreover, there is a portion that is horizontally displaced from each other and does not overlap in the vertical plane. Therefore, if the width Wb is the width of the two occupied areas E3 and E4 in a plan view, the width Wb is larger than the width Wa.

FIG. 6A schematically shows two occupied areas E3 and E4 in a plan view by hatching. It can be seen that the occupied areas E3 and E4 each have a long shape in the tilting direction of the post 121 (left-right direction in FIG. 6A) and are displaced in the tilting direction of the post 121.

FIG. 6B shows the occupied area of the entire post 121 in the mounting groove 114 by hatching. The occupied area E3 is the occupied area at the height position HL of the bottom surface B of the mounting groove 114, and the occupied area E4 is the occupied area at the height position HH of the frontage of the mounting groove 114. The state in which the areas E3 and E4 are viewed in a plan view represents the occupied area of the entire post 121 in the mounting groove 114.

In the present embodiment, of the occupied area of the entire post 121 in the mounting groove 114, the occupied area of the post 121 (see FIG. 5A) mounted at right angles to the pedestal 111 is EA, tilted to the pedestal 111. The occupied area of the attached post 121 (see FIG. 5B) is referred to as EB.

In FIG. 6C, in order to compare the occupied area EA and the occupied area EB, both are superimposed and shown by hatching. Comparing the occupied area EA and the occupied area EB, the length in the direction orthogonal to the inclination direction of the post 121 (the left-right direction in FIG. 6C) does not change, but the occupied area EB has the inclination of the post 121. You can see that it is getting longer in the direction.

From the above description, it can be said that the occupied area of the post 121 in the mounting groove 114 is the area occupied in the horizontal plane when the entire region of the post 121 entering the mounting groove 114 is made into a horizontal cross section.

7 (A) and 7 (B) show the occupied areas EA and EB of the post 121 in the mounting groove 114 by hatching according to the post 121 of the embodiment shown in FIGS. 1 to 4. FIG. 7A is an occupied area EA of the post 121 attached to the pedestal 111 at a right angle, and FIG. 7B is an occupied area EB of the post 121 inclined and attached to the pedestal 111.

As shown in FIG. 7 (A), the occupied area EA of the post 121, which was uniform over the entire circumference when mounted on the pedestal 111 at a right angle, is tilted when the post 121 is tilted as shown in FIG. 7 (B). It becomes an occupied area EB that extends in the direction (left-right direction in FIG. 7) and becomes larger. Therefore, the sign column 101 of the present embodiment assumes a state in which the post 121 is tilted to the maximum so as to cope with the increase in the occupied area of the post 121, and at this time, the post 121 occupies the mounting groove 114. The groove width of the mounting groove 114 is set to the same width as the maximum width based on the location of the maximum width.

The "groove width of the mounting groove 114 appropriately set" has been described above.

The action will be described. According to the sign column 101 of the present embodiment, the post 121 can be arranged vertically by a simple method of setting the arrangement position of the pair of through holes 125 according to the inclination angle of the installation place. Moreover, once the arrangement position of the pair of through holes 125 is determined, it is easy to mass-produce the sign pillar 101 in which the post 121 is inclined by the same angle with respect to the pedestal 111. Therefore, it is possible to facilitate the manufacture of the sign column 101 in which the post 121 can be arranged vertically.

In the installation work of the sign column 101 manufactured in this way, it is only necessary to fix the pedestal 111 to the installation place so that the post 121 is vertical, and the workability is good. Therefore, even in a place where the inclination of the installation place where the sign pillar 101 is installed is continuous over a long distance, the work load of the work of installing the sign pillar 101 can be lightened and the workability can be improved.

Yet another advantage of the sign column 101 of the present embodiment is that the tilt angle of the post 121 with respect to the pedestal 111 can be set steplessly, at which time the tilt angle of the post 121 can be any angle of the component. It is possible to make it common.

As described above, the tilt angle of the post 121 with respect to the pedestal 111 depends on the tilt angle of the reference line L2 with respect to the horizontal line HL2 orthogonal to the axis O2 of the post 121. Of course, the reference line L2 is virtual, and its inclination angle can be freely set. Therefore, the setting of the tilt angle of the post 121 with respect to the pedestal 111 is stepless, and the post 121 can be arranged vertically according to the tilted state of various installation locations.

Moreover, the pedestal 111, the post 121, and the fixture 131, which form the marker pillar 101, are not subject to physical restrictions such as different dimensions and angles depending on the inclination angle of the post 121 with respect to the pedestal 111. Common parts can be used for the pedestal 111, the post 121, and the fixative 131 at any tilt angle. Therefore, it is possible to standardize the parts.

Yet another advantage of the marker column 101 of the present embodiment is that the mounting groove 114 has a circular shape in a plan view. The circular mounting groove 114 has good workability due to the simplicity of its shape, and contributes to facilitation of manufacturing.

As described above, by mounting the sign column 101 with the post 121 tilted with respect to the pedestal 111, the post 121 can be arranged vertically even if the installation location is tilted. However, the mode of use of the marker pillar 101 of the present embodiment is not limited to the mode of vertically arranging the post 121. It is also permissible to use the sign column 101 in a state where the post 121 is set at an angle other than vertical.

Another embodiment will be described with reference to FIG. The same parts as those of the embodiments shown in FIGS. 1 to 7 (A) and 7 (B) are indicated by the same reference numerals, and the description thereof will be omitted.

The boss 113 of the present embodiment has a shape in which only the first protrusion 114A is provided and the second protrusion 114B is omitted. Therefore, the mounting groove 114 is not formed, and the mounting wall W is composed of only the first wall W1.

According to the present embodiment, the lower end portion 121L of the post 121 fits into the mounting wall W of only the first wall W1 provided on the boss 113, and is fixed to the pedestal 111 by the fixing tool 131. The structure for inclining the post 121 with respect to the pedestal 111, the method for attaching the post 121 to the pedestal 111, and the like are the same as those of the embodiments shown in FIGS. 1 to 7 (A) and 7 (B).

In the present embodiment, when the post 121 is attached to the pedestal 111, the second protrusion 114B forming the second wall W2 is not provided, so that the mounting wall W (the first) of the first protrusion 114A provided on the boss 113 is provided. It is possible to facilitate the fitting work of the post 121 with respect to one wall W1). The shape of the boss 113 is also simplified, the manufacturing cost of the pedestal 111 can be reduced, and the processing of the fixing hole 115 can be simplified. Since the second protrusion 114B is omitted, it is possible to use a post 121 that is not hollow.

Another embodiment will be described with reference to FIG. The same parts as those of the embodiments shown in FIGS. 1 to 7 (A) and 7 (B) are indicated by the same reference numerals, and the description thereof will be omitted.

The boss 113 of the present embodiment has a shape in which only the second protrusion 114B is provided and the first protrusion 114A is omitted. Therefore, the mounting groove 114 is not formed, and the mounting wall W is composed of only the second wall W2.

Since the mounting wall W is composed of only the second wall W2, the fixing hole 115 of the present embodiment penetrates only the second wall W2 provided in the second protrusion 114B. At this time, the fixing holes 115 penetrating the two places of the second wall W2 are different from the embodiments shown in FIGS. 1 to 7 (A) (B) and FIG. The 131 is press-fitted. By this press fitting, the post 121 is fixedly attached to the pedestal 111.

According to the present embodiment, the lower end portion 121L of the post 121 fits into the mounting wall W of only the second wall W2 provided on the boss 113, and is fixed to the pedestal 111 by the fixing tool 131. At this time, since the boss 113 does not have the first protrusion 114A forming the first wall W1, the post 121 can be easily inserted. Further, since the shape of the boss 113 is simplified, the manufacturing cost thereof can be reduced and the processing of the fixing hole 115 can be simplified.

Another embodiment will be described with reference to FIG. The same parts as those of the embodiments shown in FIGS. 1 to 7 (A) and 7 (B), 8 and 9, respectively, are indicated by the same reference numerals, and description thereof will be omitted.

The post 121 of the present embodiment has a lower end portion 121L cut so as to be parallel to a line connecting a pair of through holes 125 (equal to a reference line L2 inclined with respect to the horizontal line HL2).

According to the marker column 101 of the present embodiment, the insertion depth of the post 121 with respect to the mounting groove 114 of the pedestal 111 can be increased. Increasing the insertion depth of the post 121 brings advantages such as improved stabilization of the support state of the post 121 and reduction of material cost by lowering the height of the boss 113.

Another embodiment will be described with reference to FIGS. 11 and 12 (A) and 12 (B). The same parts as those of the embodiments shown in FIGS. 1 to 7 (A) and 7 (B) are indicated by the same reference numerals, and the description thereof will be omitted.

The mounting groove 114 of the present embodiment has a groove width in the direction connecting the pair of fixing holes 115 (inclination direction of the post 121) wider than the groove width in the direction orthogonal to this direction.

Various modifications and changes are possible at the time of implementation.

For example, the post 121 may have a non-hollow structure as well as a hollow structure as introduced in the above embodiment. In this case, when the application is made to the pedestal 111 provided with the mounting groove 114, the bottom portion of the post 121 interferes with the second protrusion 114B constituting the mounting groove 114. This problem is solved by providing a recess in the bottom of the post 121 to prevent interference with the second protrusion 114B.

In the above embodiment, the pedestal 111 in which the boss 113 is integrally provided on the base 112 has been introduced, but in the implementation, the base 112 and the boss 113 are prepared separately, and the boss 113 is bonded to the base 112, for example. It may be fixed and integrated by a method such as. The fixing of the boss 113 to the base 112 may be realized by any method such as heat welding as well as adhesion.

The pedestal 111 does not have to have a structure in which the boss 113 is provided on the base 112 in the first place, that is, the portion that is the base 112 and the portion that is the boss 113 are not physically separated. For example, as shown in FIG. 17, a boss 113 having a portion acting as a base 112 fixed to an installation location and a mounting groove 114 for mounting a post 121 on a pedestal 111 in the form of a single block. It may have a part that plays a role. Conceptually, the pedestal 111 in such a form can be interpreted as having neither the base 112 nor the boss 113, or it is interpreted that the base 112 has the mounting groove 114 without the boss 113. You can also.

As for the form of the pedestal 111, various forms are allowed. For example, a boss 113 may be provided only on a part of the upper surface BU of the base 112, and a mounting wall W may be provided straddling the upper surface BU of the base 112 and the upper surface of the boss 113.

In the pedestal 111 of various forms described above, it is possible to apply various forms of the mounting wall W. For example, the form of the mounting groove 114 having the first wall W1 and the second wall W2 (such as FIGS. 1 to 7 (A) and (B)) and the form of only the first wall W1 (see FIG. 8). Also, the form of only the second wall W2 (see FIG. 9) can be applied to the pedestal 111 of various forms.

The bottom surface B of the mounting groove 114 does not necessarily have to be horizontal. When the bottom surface B of the mounting groove 114 is not horizontal, under the condition that the pedestal 111 is installed on a horizontal surface, the post 121 inserted in the mounting groove 114 does not have the axis O2 naturally oriented vertically. The form of the bottom surface B of the mounting groove 114 that brings about such a state is also allowed.

The structure for fixing the fixture 131 to the pedestal 111 is not only a structure in which the screw portion 134 of the fixture 131 is press-fitted into the fixing hole 115, but also, for example, a nut is screwed into the screw portion 134 and tightened. A structure may be adopted. Alternatively, the end of the shoulder 133 of the fixture 131 may be abutted against the inner peripheral wall of the post 121 to fix the post 121 to the pedestal 111.

Any other modifications or changes are allowed in the implementation.
