As shown in FIG. 11, when traffic is restricted on an expressway or the like, the rubber cones 1 are placed on the road RD at predetermined intervals over the vehicle restricted section to ensure that traffic is restricted. to the driver of the running vehicle VH.

In the following description, the direction in which the sensor 60 is positioned with respect to the cone central axis Cac, which is the central axis of the rubber cone 1 in an upright state to which the fixture 20 (FIG. 1) is attached when viewed in plan view, is the rear side (back side). ), the direction in which the cone center axis Cac of the rubber cone 1 is positioned with respect to the sensor 60 is the front side (front side), and the left and right sides as viewed from the worker facing the front side of the rubber cone 1 are the left side and the right side, respectively. , the upper side and the lower side are further defined and explained. Further, hereinafter, the direction parallel to the cone center axis Cac of the rubber cone 1 along the vertical direction of the rubber cone 1 in the upright state is defined as the axial direction. Further, the central axis of the fixture 20 along the vertical direction of the fixture 20 in the state of being mounted on the rubber cone 1 in the upright state is defined as the fixture central axis Caf. In the attached state, the cone central axis Cac and the fixture central axis Caf are aligned (Fig. 1). Below, the cone central axis Cac and the fixture central axis Caf are also collectively referred to as the central axis Ca. Further, the direction along the outer periphery of the main body portion 4 (described later) of the rubber cone 1 around the central axis Ca when the attachment 20 and the rubber cone 1 are viewed in a plan view is defined as the circumferential direction. Regarding the axial direction, the direction in which the mounting fixture 20 approaches downward from the upper side of the rubber cone 1 when the mounting fixture 20 is mounted on the rubber cone 1 is also referred to as a mounting direction Df. The upward direction in which the fitting 20 is separated from the rubber cone 1 when it is detached from the cone 1 is also called a detaching direction Dd. Further, the direction perpendicular to the circumferential direction when viewed from above the central axis Ca and approaching the central axis Ca is defined as the inner circumferential direction, and the direction orthogonal to the circumferential direction when viewed from above the central axis Ca is separated from the central axis Ca. The direction to do so is called the outer peripheral direction. Further, the direction orthogonal to the axial direction and along the inner peripheral direction and the outer peripheral direction is also called the radial direction. Furthermore, regarding the radial direction, the side close to the central axis Ca is also called the inner side or the inner peripheral side, and the side separated from the central axis Ca is also called the outer side or the outer peripheral side.

The bottom part 2 is rectangular in plan view, thinly formed vertically, and has a circular opening in the center, so that when the rubber cone 1 is placed on the road, the lower surface thereof contacts the road.

The body portion 4 has a hollow conical shape as a whole with a predetermined thickness, and stands upright from the bottom portion 2 along the cone central axis Cac. Further, the body portion 4 has a truncated cone-shaped internal space 6 in which the upper end portion and the lower end portion are open. Further, the body portion 4 has a shape in which the upper end portion (that is, the top of the head) is cut off along the horizontal direction, and a circular opening 8 is formed in the upper end portion in a plan view. Further, on the outer peripheral side of the opening 8, an upper edge surface 10, which is a ring-shaped (ring-shaped) plane in plan view along the horizontal direction, is formed with a width corresponding to the thickness of the main body 4.

Further, a groove portion 14 is formed in the body portion 4 . This groove portion 14 is a recess that is recessed from the fitting surface 12 toward the outer peripheral side so as to have a depth in the radial direction that is about half the thickness of the main body portion 4, and is about 30 [°] in plan view. It is formed along the circumferential direction over the range of the circumferential direction. Further, the groove portion 14 is continuously formed along the axial direction from the upper end portion (that is, the upper edge surface 10) of the main body portion 4 toward the mounting direction Df by the groove portion length L1. Further, the body portion 4 has a projecting portion locking surface 16 which is a flat surface facing the mounting direction Df side along the horizontal direction at a location other than the groove portion 14 in the circumferential direction at the same axial position as the lower end portion of the groove portion 14 . is formed. For this reason, the projecting portion locking surface 16 is formed to face the mounting direction Df side at a position axially extending from the upper edge surface 10 by the groove portion length L1 toward the mounting direction Df.

In such a configuration, the rubber cone 1 as a member to which the attachment is attached is moved in the mounting direction Df along the downward direction from the upper side to the lower side of the rubber cone 1 while the attachment 20 is gripped by the worker. Then, the fitting 20 is inserted into the internal space 6 from the opening 8 while the fitting 20 is properly rotated, so that the fitting 20 is attached to the rubber cone 1 (details will be described later).

As shown in FIGS. 4, 5, 6, and 7, the fixture 20 is formed by molding resin, has a shape like an English capital letter "T" when viewed from the side, and has a lower side (mounting It has a shaft portion 22 formed on the side of the direction Df) and a body portion 40 formed on the upper side (the side of the attachment/detachment direction Dd).

[2-1. Configuration of Shaft Part]
The shaft portion 22 extends along the axial direction and has a hollow, substantially truncated cone shape that is open on the attachment/detachment direction Dd side. This shaft portion 22 is a portion that is not exposed to the outside of the rubber cone 1 by being accommodated in the internal space 6 of the rubber cone 1 in the attached state, and has a fitting portion 26 on the upper side and an insertion portion for stacking on the lower side. 28 are formed respectively. The center axis of this shaft portion 22 is the fixture center axis Caf.

[2-1-1. Configuration of Fitting Portion]
The fitting portion 26 occupies about half of the shaft portion 22 on the attachment/detachment direction Dd side, and has a cylindrical shape with an outer diameter slightly narrower than the inner diameter of the opening 8 of the rubber cone 1 . The fitting portion 26 is fitted to the inner peripheral side of the fitting surface 12 in the mounted state.

[2-1-2. Configuration of Insertion Portion for Stacking]
The stacking insertion portion 28 occupies about a half range of the shaft portion 22 on the mounting direction Df side, and the end portion on the detachment direction Dd side is configured to be shorter than the outer diameter of the fitting portion 26 in the mounting direction. It has a truncated cone shape that tapers toward Df. The overlapping insertion portion 28 is located on the mounting direction Df side of the fitting surface 12 in the mounted state, and is located on the inner peripheral side of the fitting portion 26 of the other fixture 20 in the overlapping state (described later). Enter the interior space 24 .

[2-1-3. Configuration of projecting portion]
A substantially rectangular parallelepiped upper projecting portion 30 having an open outer peripheral side protrudes outward from the outer peripheral surface of the fitting portion 26 on the mounting direction Df side, that is, the axially central portion of the shaft portion 22 . . The end portion of the upper projecting portion 30 on the outer peripheral side protrudes further to the outer peripheral side than the outer peripheral surface of the end portion of the insertion portion 28 on the mounting direction Df side. The upper protruding part 30 is rotated 180[°] with respect to the sensor 60 (to be described later) around the central axis Caf of the fixture when viewed from above the central axis Caf of the fixture, that is, the central axis Caf of the fixture. It is located on the opposite side of the sensor 60 as an axis. Further, the axial distance between the main body mounting surface 42S (described later) and the end surface of the upper protrusion 30 on the detachment direction Dd side is the bottom upper protrusion spacing L2 (FIG. 6). This bottom surface upper projection interval L2 is set slightly longer than the groove length L1.

In addition, a substantially rectangular parallelepiped lower projecting portion 32 whose outer peripheral side is open extends from the outer peripheral surface of the end portion of the insertion portion 28 on the mounting direction Df side, that is, the end portion of the shaft portion 22 on the mounting direction Df side. protruding to A protrusion spacing L3, which is the axial spacing between the end face of the upper protrusion 30 on the mounting direction Df side and the end face of the lower protrusion 32 on the detachment direction Dd, is set slightly longer than the groove length L1.

As simplistically shown in FIG. 8, rotation along the circumferential direction between the upper protruding portion 30 and the lower protruding portion 32 about the mounting tool central axis Caf when viewed from above the mounting tool central axis Caf. The angle is defined as a protrusion arrangement rotation angle Ar. The lower protruding part 32 is arranged at a position rotated clockwise by the protruding part arrangement rotation angle Ar with respect to the upper protruding part 30 when viewed from the attachment/detachment direction Dd on the fixture central axis Caf. Here, in order to prevent the mounting fixture 20 from coming off the rubber cone 1 even when the vehicle VH collides with the rubber cone 1, the inventors of the present invention believe that the protrusion arrangement rotation angle Ar should be 40[°] or more. This has been clarified by experiments by et al. In addition, as an angle at which a worker can attach the fixture 20 to the rubber cone 1 with one twist (that is, an angle at which the attachment work is not complicated), the protrusion arrangement rotation angle Ar may be 75 [°] or less. This has been clarified by the experiments of the inventors. Therefore, the protrusion arrangement rotation angle Ar is preferably in the range of 40[°] or more and 75[°] or less. In the present embodiment, the protrusion arrangement rotation angle Ar is set to 45[°]. there is

[2-1-4. Configuration of slit]
Further, the fitting 20 is formed with an overlap slit 34 along the axial direction at the fitting portion 26 of the shaft portion 22 on the detachment direction Dd side of the lower projecting portion 32 . The overlapping slit 34 is arranged at the same circumferential position as the lower projecting portion 32 . The overlapping slit 34 has an end portion on the detachment direction Dd side formed in the main body bottom portion 42 (to be described later), the end portion on the detachment direction Dd side is open, and extends axially toward the mounting direction Df. Extends about the length of the insertion portion 28 at the time of stacking so as to pierce the shaft portion 22 along, and communicates the inner space 24 of the shaft portion 22 with the space on the outer peripheral side, and the end portion on the mounting direction Df side is closed. . Further, the overlapping slit 34 is an opening in the main body bottom portion 42 (to be described later) that has a shape similar to that of the lower projecting portion 32 when viewed from the attachment/detachment direction Dd and has a slightly larger width in the circumferential direction. ing.

As shown in FIG. 9, the overlapping slit 34 is provided on the other mounting fixture 20 arranged on the upper side in FIG. The lower protruding portion 32 of the fixture 20 enters from the attachment/detachment direction Dd side, thereby inserting the overlapping insertion portion 28 of the other fixture 20 into the internal space 24 of the fitting portion 26 of the one fixture 20. . As a result, the fixture 20 can stack a plurality of fixtures 20 along the axial direction. This state is hereinafter also referred to as a superimposed state. In this overlapped state, the end surface of the upper projection 30 of the other fixture 20 on the mounting direction Df side is in contact with the main body mounting surface 42S (described later) of the other fixture 20 .

[2-1-5. Configuration of drainage hole]
Further, the fixture 20 is formed with a drain hole 29 at the end of the shaft portion 22 on the mounting direction Df side. The drain hole 29 has a circular shape, and allows the internal space 24 of the shaft portion 22 and the space on the mounting direction Df side of the shaft portion 22 to communicate with each other. The drain hole 29 discharges rainwater or the like that has entered the internal space 24 through the main body bottom opening 42a (described later) and the overlapping slit 34 to the outside of the internal space 24, and the rainwater or the like is retained in the internal space 24. The performance of the sensor 60 is ensured by preventing the accumulation of water.

[2-2. Configuration of main unit]
The body portion 40 mainly includes a body bottom portion 42, a body portion outer wall portion 44, and a sensor holding portion 50, which are exposed to the outside of the rubber cone 1 in the mounted state.

[2-2-1. Configuration of the bottom of the main body]
The main body bottom portion 42 has a shape like an English capital letter “U” when viewed along the axial direction, and is connected to the end portion of the fitting portion 26 of the shaft portion 22 on the detachment direction Dd side. It is an axially thin plate-like member extending from the end portion of the joining portion 26 on the detachment direction Dd side to the outer peripheral side. For this reason, the bottom portion 42 of the main body has an outer shape larger than that of the shaft portion 22 , that is, an outer shape larger than the inner diameter of the opening 8 of the rubber cone 1 . In the central portion of the bottom portion 42 of the main body, there is a main body bottom opening that allows communication between the inner space 24 of the shaft portion 22 and the mounting and dismounting direction Dd side of the shaft portion 22, and opens the inner space 24 toward the mounting and demounting direction Dd side. 42a is formed.

Further, on the mounting direction Df side of the main body bottom portion 42, a main body mounting surface 42S that is a flat surface along the radial direction is formed. The main body placement surface 42S abuts on the upper edge surface 10 of the rubber cone 1 when the attachment 20 is attached to the rubber cone 1. As shown in FIG. As a result, the attachment 20 is prevented from falling into the inner space 6 of the rubber cone 1 by hooking the bottom portion 42 of the main body to the upper edge surface 10 of the rubber cone 1 in the attached state.

[2-2-2. Configuration of Main Body Outer Wall]
[2-2-2-1. Overall configuration of outer wall of main body]
The outer wall portion 44 of the main body portion is erected from the outer peripheral portion of the bottom portion 42 of the main body portion at a right angle toward the attachment/detachment direction Dd. The outer wall portion 44 of the main body has an arc shape along a part of a concentric circle with the bottom opening 42a of the main body, on the opposite side (the front side rotated by 180[°]) from the sensor holding portion 50 across the center axis Caf of the fixture. In addition, the width of the sensor holding portion 50 increases toward both ends in the left-right direction. Further, on the outer peripheral side surface of the main body outer wall section 44, a main body outer side surface 44S, which is a surface facing the outer peripheral side along the axial direction, is formed.

[2-2-2-2. Configuration of mark part]
An upper projecting portion mark 46 and a lower projecting portion mark 48 are formed on the outer wall portion 44 of the main body portion. The upper protrusion mark 46 as the second mark is formed at the same position as the upper protrusion 30 in the circumferential direction, and has an upper protrusion mark upper portion 46u and an upper protrusion mark side portion 46s. there is The upper protruding portion mark upper portion 46u protrudes from the upper end portion of the main body portion outer wall portion 44 in the attachment/detachment direction Dd. The upper protruding portion mark side surface portion 46s protrudes toward the outer peripheral side from the vicinity of the upper end portion to the lower end portion of the main body portion outer side surface 44S.

The lower protrusion mark 48 as the first mark is formed at the same position as the lower protrusion 32 in the circumferential direction, and has a lower protrusion mark upper portion 48u and a lower protrusion mark side portion 48s. have. The lower protrusion mark upper portion 48u protrudes from the upper end portion of the main body outer wall portion 44 toward the attachment/detachment direction Dd by the same height as the upper protrusion mark upper portion 46u. The lower projecting portion mark side surface portion 48s protrudes toward the attachment/detachment direction Dd by the same height as the upper projecting portion mark upper portion 46u in the vicinity of the lower end portion of the main body portion outer side surface 44S.

As described above, the outer wall portion 44 of the main body is formed with the upper protrusion mark 46 and the lower protrusion mark 48 at the same circumferential positions corresponding to the upper protrusion 30 and the lower protrusion 32, respectively. . For this reason, in the attached state, the upper projecting portion 30 and the lower projecting portion 32 are housed in the internal space 6 of the rubber cone 1 , so that the upper projecting portion 30 and the lower projecting portion 32 are located outside the main body portion 4 . Even if the operator cannot see the upper protrusion 30 and the lower protrusion 32 visually, the upper protrusion mark 46 and the lower protrusion mark 48 can be exposed to the outside of the rubber cone 1. . As a result, the mounting fixture 20 allows the worker to visually recognize the rotational positions of the upper protruding part 30 and the lower protruding part 32 in the circumferential direction when the mounting fixture 20 is mounted. It can be used as a guideline for operation.

The upper protrusion mark side surface 46s extends from the vicinity of the upper end to the lower end of the main body outer side surface 44S, while the lower protrusion mark side surface 48s extends to the lower end of the main body outer side surface 44S. It is formed only in the vicinity. For this reason, the mounting fixture 20 is based on the actual axial positional relationship between the upper projecting portion 30 and the lower projecting portion 32, and the axial positions of the upper projecting portion mark side surface portion 46s and the lower projecting portion mark side surface portion 48s. relationship can be matched. Accordingly, the mounting fixture 20 allows the worker to visually recognize the axial positions of the upper protruding portion 30 and the lower protruding portion 32 in the attached state.

[2-2-3. Configuration of sensor holder]
The sensor holding portion 50 is positioned at a position rotated 180[°] with respect to the upper protruding portion 30 about the central axis Caf of the fixture, that is, on the opposite side of the upper protruding portion 30 about the central axis Caf of the fixture. . Therefore, the sensor holding portion 50 and the sensor 60 held by the sensor holding portion 50 are not positioned on the fixture central axis Caf, but are arranged at positions separated from the fixture central axis Caf to the outer peripheral side. It is

The sensor holding portion 50 has a cross section along the axial direction as a whole that is shaped like an English capital letter "U" with an outer peripheral side open, and a sensor side contact portion 50a, a sensor protection eaves 50b, and a sensor holding bottom portion 50c. formed. The sensor side contact portion 50a is a plate-like member formed with a flat surface facing the outer peripheral side, and the sensor 60 is screwed thereon. The sensor protection canopy 50b is a plate-like member projecting perpendicularly from the end of the sensor side contact portion 50a on the detachment direction Dd side toward the outer peripheral side. to prevent The sensor holding bottom portion 50c is a plate-shaped member that protrudes toward the outer peripheral side at right angles from the end portion of the sensor side contact portion 50a on the mounting direction Df side. A sensor 60 can be attached to and detached from the sensor holder 50 .

[2-3. Configuration of sensor]
The sensor 60 as a communication device is, for example, a sensor having a wireless communication function that detects vibrations and tilts. When abnormal vibrations or tilts are detected, it is determined that the rubber cone 1 has fallen, and a predetermined warning is issued by the wireless communication unit. Notify the notification terminal. The warning notification terminal issues an alarm when a predetermined notification is received from the sensor 60 .

[3. Mounting process of fitting to rubber cone]
In such a configuration, a procedure for attaching the fixture 20 gripped by the operator to the rubber cone 1 will be described with reference to FIG. 10 . First, with the fitting 20 positioned above the rubber cone 1 in the upright state (on the attachment/detachment direction Dd side), the circumferential positions of the lower projecting portion 32 of the fitting 20 and the groove portion 14 of the rubber cone 1 are be matched. Next, as shown in FIG. 10A, until the upper protruding portion 30 of the fitting 20 is caught by the upper edge surface 10 of the rubber cone 1 and the fitting 20 stops moving in the mounting direction Df any more, the fitting 20 is moved. is moved in the mounting direction Df (downward), and the shaft portion 22 of the fixture 20 is inserted into the internal space 6 from the opening 8 of the rubber cone 1 . As described above, since the projection interval L3 is set slightly longer than the groove length L1, in the state shown in FIG. The end surface is located on the mounting direction Df side of the protrusion locking surface 16 of the rubber cone 1 .

Next, when the upper protruding portion 30 of the fitting 20 is caught by the upper edge surface 10 of the rubber cone 1 and the fitting 20 does not move further in the mounting direction Df, as shown in FIG. 10B, the fitting 20 is formed. is rotated by 45[°], which is the protrusion arrangement rotation angle Ar, toward the mounted rotation direction Drf that is clockwise in plan view. As a result, the upper projecting portion 30 of the fitting 20 and the groove portion 14 of the rubber cone 1 are aligned in the circumferential direction. In the state shown in FIG. 10C, the end surface of the lower projecting portion 32 of the fixture 20 on the attachment/detachment direction Dd faces the projecting portion locking surface 16 of the rubber cone 1 in the vertical direction.

Next, as shown in FIG. 10(C), the fixture 20 is moved in the mounting direction Df, and the shaft portion 22 of the fixture 20 is further inserted into the internal space 6 from the opening 8 of the rubber cone 1, and the mounting is performed. The main body mounting surface 42S (FIGS. 5 and 6) of the tool 20 comes into contact with the upper edge surface 10 of the rubber cone 1 (FIGS. 2 and 3). As described above, the interval L2 between the bottom upper protrusions is set to be slightly longer than the length L1 of the groove, so in this mounted state, the end surface of the upper protrusion 30 of the fixture 20 on the attachment/detachment direction Dd side is a rubber cone. 1 is located on the mounting direction Df side of the protrusion locking surface 16 . Therefore, the mounting fixture 20 is rotatable with respect to the rubber cone 1 with the upper protruding part 30 located on the mounting direction Df side of the groove part 14 . In this mounted state, the fitting 20 is appropriately rotated in the circumferential direction with respect to the rubber cone 1, and the orientation of the fitting 20 is adjusted. When the orientation of the fixture 20 is adjusted, the end surfaces of the lower protrusion 32 and the upper protrusion 30 of the fixture 20 on the attachment/detachment direction Dd face the protrusion locking surface 16 of the rubber cone 1 in the vertical direction. is doing.

[4. Positional relationship between the rubber cone and the sensor when the rubber cone is installed]
As shown in FIG. 11, the fixture 20 is oriented with respect to the rubber cone 1 installed on the side of the road RD so that the sensor 60 is positioned on the vehicle traveling direction Dv side, which is the traveling direction of the vehicle VH traveling on the road RD. , that is, the orientation of the fixture 20 is adjusted so that the sensor 60 faces the vehicle traveling direction Dv with respect to the rubber cone 1 . Therefore, the mounting fixture 20 is in a state in which the body portion 40 of the mounting fixture 20 and the rubber cone 1 are interposed between the mounting fixture 20 and the vehicle VH traveling in the vehicle traveling direction Dv. Therefore, when the vehicle VH traveling in the vehicle traveling direction Dv collides with the rubber cone 1 or the mounting fixture 20, the mounting fixture 20 can prevent the sensor 60 from directly contacting the vehicle VH and being destroyed.

[5. effects, etc.]
In the above configuration, the fixture 20 has a protrusion arrangement rotation angle Ar, which is a rotation angle between the upper protrusion 30 and the lower protrusion 32 in the circumferential direction about the fixture central axis Caf, set to 40[° ] or more, 45[°]. Therefore, when the fitting 20 is attached to the rubber cone 1, the lower protruding portion 32 and the groove portion 14 are aligned in the circumferential direction, and the lower protruding portion 32 is mounted on the attachment/detachment direction Dd side. From the state in which the end face is positioned on the mounting direction Df side of the rubber cone 1 with respect to the protrusion locking surface 16 (FIG. 10B), the protrusion arrangement rotation is performed as shown in FIG. 10C. When rotated in the mounting rotation direction Drf by the angle Ar, the lower protrusion 32 rotates in the mounting rotation direction Drf by the protrusion arrangement rotation angle Ar with respect to the groove 14 . By setting the protrusion arrangement rotation angle Ar to 40[°] or more in this way, the attachment 20 is rotated with respect to the rubber cone 1 by applying an impact to the rubber cone 1 and the attachment 20 in the attached state. Even so, the possibility that the groove 14 and the lower protruding portion 32 are aligned in the circumferential direction can be extremely reduced. For this reason, the mounting fixture 20 maintains a state in which the end surface of the lower projecting portion 32 on the attachment/detachment direction Dd side is positioned on the mounting direction Df side of the projecting portion locking surface 16 of the rubber cone 1 and faces the vertical direction. 32 can be hooked on the projecting portion locking surface 16 to prevent separation from the rubber cone 1 when the rubber cone 1 is overturned.

In addition, the mounting fixture 20 has a protrusion arrangement rotation angle Ar set to 45[°], which is 75[°] or less, at which the mounting fixture 20 can be easily attached to the rubber cone 1 with one twist. Therefore, when the mounting fixture 20 is mounted on the rubber cone 1, the upper protruding part 30 is caught by the upper edge surface 10 (FIG. 10(B)), and the mounting fixture 20 is only twisted once in the mounting rotation direction Drf. (only rotated by 45[°]), the upper protruding portion 30 and the groove portion 14 can be aligned in the circumferential direction. Therefore, the attachment tool 20 can be attached to the rubber cone 1 with one twist by a worker, and the attachment property can be improved. Further, when the attachment tool 20 is removed from the rubber cone 1, the upper protruding part 30 and the groove part 14 are aligned in the circumferential direction, and the attachment tool 20 rotates 45 [ in the direction opposite to the rotation direction Drf at the time of attachment. °] The positions of the lower protruding portion 32 and the groove portion 14 in the circumferential direction can be aligned simply by rotating. In particular, a vehicle-restricted section at a construction site such as an expressway often extends several kilometers depending on the case, and a large number of rubber cones 1 are installed. Therefore, it is useful to ensure the attachment of the fitting 20 to the rubber cone 1 .

Here, due to the structure of the human body, it is easier for the worker to rotate the right arm clockwise than to rotate it counterclockwise when the right arm is extended. Therefore, when the mounting tool 20 is attached to the rubber cone 1 and the mounting tool 20 is held and rotated with the right hand, the worker is more likely to rotate the right arm clockwise than counterclockwise. On the other hand, the fixture 20 is located at a position where the lower protruding part 32 is rotated clockwise from the upper protruding part 30 by the protruding part arrangement rotation angle Ar when viewed from the attachment/detachment direction Dd on the central axis Caf of the fixture. placed in For this reason, the fixture 20 can be rotated clockwise from the state shown in FIG. 10(B). When attaching 20, the fixture 20 can be easily rotated.

In this manner, the mounting fixture 20 sets the protrusion arrangement rotation angle Ar to 40[°] or more and 75[°] or less. For this reason, the mounting fixture 20 prevents the mounting fixture 20 from being separated from the rubber cone 1 when the rubber cone 1 is overturned, while controlling the amount of rotation that the worker rotates the mounting fixture 20 during the mounting work on the rubber cone 1. It can be greatly reduced and the mountability can be improved.

Further, the mounting fixture 20 is formed with an overlapping slit 34 along the axial direction at the same circumferential position as the lower projecting portion 32 on the detachment direction Dd side of the shaft portion 22. . For this reason, the mounting fixture 20 can be adjusted in the mounting and demounting direction of the other mounting fixture 20 with the position of the lower protruding portion 32 aligned with the position of the overlapping slit 34 on the mounting and demounting direction Dd side of the other mounting fixture 20 . The shaft portion 22 can be inserted into the internal space 24 of the shaft portion 22 of the other fixture 20 by inserting the lower protruding portion 32 of itself into the overlapping slit 34 from the Dd side. As a result, since a plurality of mounting fixtures 20 can be stacked along the axial direction, the mounting fixtures 20 can be easily carried in a stacked state, and the labor for transportation can be saved. In addition, when a plurality of fixtures 20 are stacked along the axial direction, the fixture 20 can occupy a smaller range in the axial direction and can be made compact.

By the way, conventionally, in a mounting tool, a construction light, or the like, which is inserted into the opening of the top of the rubber cone 1, which is a cut cone, there was no need to open the end of the hollow shaft in the attachment/detachment direction. It is not necessary to disturb the balance and dispose the sensor at a position spaced apart from the center axis of the fixture to the outer peripheral side without being positioned on the center axis of the fixture.

On the other hand, in the fixture 20 according to the present embodiment, the sensor 60 is positioned on the fixture center axis Caf, although there is a possibility that the center of gravity balance of the fixture 20 to which the sensor 60 is attached may be slightly disturbed. Instead, it was arranged at a position spaced outward from the central axis Caf of the fixture. Therefore, the attachment tool 20 can open the end portion of the hollow shaft portion 22 on the attachment/detachment direction Dd side, and allow the inner space 24 and the attachment/detachment direction Dd side of the shaft portion 22 to communicate with each other. Therefore, the fitting 20 inserts the insertion portion 28 of the shaft portion 22 into the shaft portion of the other fitting 20 so that the lower protruding portion 32 of the fitting 20 is inserted into the stacking slit 34 of the other fitting 20 . It can be inserted into the interior space 24 at 22 .

Here, conventionally, as a method of integrating the rubber cone and the sensor, a mounting fixture to which the sensor is fixed is attached to the neck portion of construction equipment such as a construction light attached to the upper end of the rubber cone. There was a way.

However, in that case, the fixture cannot be attached to the rubber cone without a construction light, so even if road construction is carried out during bright hours such as the daytime when construction lights are not needed, the fixture alone cannot be used. Instead, it is necessary to carry the unnecessary construction light to which the fixture is fixed, which becomes a useless load, requiring the use of a large truck or an increase in the number of trucks. For this reason, there has been a demand to attach sensors to rubber cones without using construction lights.

In contrast, in the fixture 20 according to the present embodiment, the fixture 20 to which the sensor 60 is fixed can be directly attached to the rubber cone 1 without using the construction light. Therefore, when carrying the fixture to the construction site, the worker only has to carry the fixture without carrying the work light. As a result, the mounting tool 20 can reduce the amount of cargo when transporting the mounting tool 20 compared with the conventional one, and the trucks for transportation can be made smaller or the number of trucks can be reduced.

By the way, as described above, the rubber cone 1 is installed on the road RD in a state in which the upper projecting portion 30 of the fixture 20 faces the vehicle VH. Therefore, when the vehicle VH collides with the mounting fixture 20, the side of the mounting fixture 20 on which the upper projecting portion 30 is provided (that is, the opposite side of the sensor 60 when viewed from the mounting direction Df) is the portion that receives the greatest impact. becomes.

On the other hand, in the mounting fixture 20, the upper projecting portion 30 is arranged on the opposite side of the sensor 60 in plan view. Therefore, the fixture 20 can strengthen the strength of the vicinity of the part of the fixture 20 where the vehicle is likely to collide directly, and the fixture 20 can be less likely to be destroyed even if the vehicle VH collides.

In addition, since the overlapping slit 34 is formed on the shaft portion 22 on the attachment/detachment direction Dd side along the axial direction of the lower protruding portion 32, the vicinity of the overlapping slit 34 in the fixture 20 is located in other places. Slightly lower strength compared to

On the other hand, the fixture 20 rotates the lower projecting portion 32 (that is, the overlapping slit 34) by the projecting portion arrangement rotation angle Ar with respect to the vicinity of the upper projecting portion 30, which is the portion that receives the most impact when the vehicle VH collides. It was arranged in a position shifted in the circumferential direction. Therefore, in the fixture 20, the vicinity of the overlapping slit 34 whose strength is reduced can be displaced from the position where the greatest impact is applied when the vehicle VH collides. The vicinity of the overlapping slit 34, whose strength is lowered by the above, can be made difficult to break.

According to the above configuration, the fixture 20 has an open upper end, is formed over a predetermined circumferential range and a predetermined axial range along the cone center axis Cac, and extends from the inner peripheral side to the outer peripheral side. The mounting direction Df along the cone center axis Cac is such that the upper protrusion 30 and the lower protrusion 32 as protrusions enter the groove 14 with respect to the rubber cone 1 as the attached device having the recessed groove 14 at the upper end. The fixture 20 is attached by being moved toward the outer periphery, and the lower protruding part 32 protruding to the outer peripheral side and the lower protruding part 32 on the side of the attachment and detachment direction Dd opposite to the mounting direction Df. An upper projecting portion 30 projecting to the side is provided, and the projecting portion arrangement rotation angle Ar, which is the angle between the lower projecting portion 32 and the upper projecting portion 30 in the circumferential direction about the fixture central axis Caf, is 40 [ °] or more and 75 [°] or less.

As a result, the mounting fixture 20 secures the holding force for the rubber cone 1, and can greatly reduce the amount of rotation of the mounting fixture 20 by a worker during the mounting work on the rubber cone 1, thereby improving the mountability.

The fitting 20 is a hollow shaft portion that extends along the fitting center axis Caf and enters the rubber cone 1 when the fitting 20 is attached to the rubber cone 1 and has an open end on the attachment/detachment direction Dd side. 22, a lower projecting portion 32 projecting from the outer peripheral surface of the shaft portion 22 toward the outer peripheral side; A slit 34 for stacking formed facing is provided.

As a result, the fitting 20 inserts the insertion portion 28 of the shaft portion 22 into the shaft of the other fitting 20 so that the lower protruding portion 32 of the fitting 20 is inserted into the stacking slit 34 of the other fitting 20 . A plurality of fixtures 20 can be inserted into the inner space 24 of the portion 22 and overlapped along the axial direction to reduce the range occupied in the axial direction.
