It has a lower part 3B in the shape of a truncated cone. The lower part of the column part 2 is fixed to the upper part 3A. Although not essential, a plurality of reflective sheets 7 are fixed around the upper portion 3A.

As shown in FIG. 2, the upper part of a bolt 8 having a male thread 4 is buried in the lower part 3B of the pedestal part 3. Therefore, the male screw 4 is firmly fixed to the base portion 3. The bolt 8 is made of metal, for example steel.

Two holes 9 are formed in the lower part 3B. The two holes 9 extend downward from the upper surface of the lower portion 3B of the base portion 3. The two holes 9 are arranged on one straight line orthogonal to the central axis Ax, and the column 2 is arranged between the two holes 9 when viewed from above. A gap G1 is provided between the two holes 9.

Although the hole 9 penetrates the lower part 3B, it does not have to. Hole 9 is used to rotate pole cone 1 around central axis Ax.

The male screw 4 is screwed into and attached to an anchor (female screw) 11 buried in the ground 10 of the road. Anchor 11 is fixed to ground 10 with an adhesive, such as mortar. The anchor 11 has a lower part 11A with a female thread formed in the center and a cylindrical upper part 11B.

A gap G2 is provided between the two holes 29. The spacing G2 is smaller than the spacing G1 between the holes 9 of the type A pole cone 1.

Although the hole 29 penetrates the lower part 23B, it does not have to penetrate therethrough. Hole 29 is used to rotate pole cone 21 around central axis Ax.

In the above configuration, by rotating the pole cone 21 around the central axis Ax, the male screw 4 can be fastened to the anchor 11 to fix the pole cone 21 to the ground 10. Further, by rotating the pole cone 21 in the opposite direction, the male screw 4 can be taken out from the anchor 11 and the pole cone 21 can be removed from the ground 10.

The male screw 4 is inserted into a cylindrical spacer 32 made of resin or metal. The spacer 32 is arranged in the internal space of the upper part 11B of the anchor 11 and is sandwiched between the bottom surface of the lower part 23B of the pedestal part 23 and the lower part 11A of the anchor 11. The spacer 32 may be formed integrally with the pedestal part 23 from the same material as the pedestal part 23.

As shown in FIG. 5, the type C pole cone 41 has a column part 2, a pedestal part 43, and a male thread 4.

The pedestal portion 43 is a circular plate having a larger area than the column portion 2. Although the specific shape and material of the pedestal part 43 are not limited, in one example, the pedestal part 43 is a solid cylinder made of an elastic material such as polyurethane, and the pedestal part 43 has a lower part of the pillar part 2. Fixed. The diameter D of the pedestal portion 43 is smaller than the interval G1 between the holes 9 of the type A pole cone 1, and approximately equal to the interval G2 between the holes 29 of the type B pole cone 21.

Although not essential, a reflective sheet 47 is fixed around the base portion 43.

As shown in FIG. 6, the upper part of the bolt 8 having the male thread 4 is embedded in the pedestal portion 43. Therefore, the male screw 4 is firmly fixed to the base portion 43.

One hole 49 is formed in the base portion 43. The hole 49 extends from the outer peripheral surface of the pedestal portion 43 toward the radially inner side of the pedestal portion 43 . Hole 49 is used to rotate pole cone 41 around central axis Ax.

In the above configuration, by rotating the pole cone 41 around the central axis Ax, the male screw 4 can be fastened to the anchor 11 to fix the pole cone 41 to the ground 10. Further, by rotating the pole cone 41 in the opposite direction, the male screw 4 can be taken out from the anchor 11 and the pole cone 41 can be removed from the ground 10.

The male screw 4 is inserted into a cylindrical spacer 52 made of resin or metal. The spacer 52 is arranged in the internal space of the upper part 11B of the anchor 11 and is sandwiched between the bottom surface of the lower part 43B of the pedestal part 43 and the lower part 11A of the anchor 11. The spacer 52 may be formed integrally with the pedestal part 43 from the same material as the pedestal part 43.

Next, a fastening tool 60 according to a first embodiment of the present invention will be described with reference to FIGS. 7 to 17. The fastening tool 60 can be used to rotate any of the type A pole cone 1, the type B pole cone 21, and the type C pole cone 41.

As shown in FIGS. 7 to 9, the fastening tool 60 has a line-symmetrical shape and includes a main part 61 and two sub-parts 62. The main part 61 and the sub-part 62 are made of metal, for example steel.

As shown in FIGS. 7 to 10, the main part 61 has a base 63, two arms 64A, 64B, two insertion projections 66, two insertion projections 68A, 68B, and two tubes 70.

Base 63 is generally a single rod. In this embodiment, the base 63 is formed by bending one round rod.

Arms 64A, 64B extend from one end of base 63 in directions away from each other. Arms 64A, 64B exist on the same plane as base 63. Each of the arms 64A, 64B has a diagonal portion connected to the base 63 and extending diagonally from the base 63, and a tip portion connected to this portion and extending parallel to the base 63.

The two insertion protrusions 66 protrude from the tip portions of the two arms 64A, 64B, respectively. Each of the insertion projections 66 is perpendicular to the arm 64A or 64B from which the insertion projection 66 projects. Therefore, the two insertion protrusions 66 are perpendicular to the plane in which the base 63 and the arms 64A, 64B exist. The two insertion protrusions 66 extend parallel to each other.

The two insertion protrusions 66 are inserted into the two holes 9 (see FIGS. 1 and 2) of the type A pole cone 1, respectively. Therefore, the spacing between the insertion protrusions 66 is equal to the spacing G1 between the holes 9.

The base portion 63, the arms 64A, 64B, and the insertion protrusion 66 can be formed, for example, by bending a single round rod having a uniform diameter along its length.

The two insertion protrusions 68A, 68B protrude from the tip portions of the two arms 64A, 64B, respectively. Specifically, the insertion projection 68A extends from the arm 64A from which the insertion projection projects toward the other arm 64B, and the insertion projection 68B extends from the arm 64B from which the insertion projection projects toward the other arm 64A. . Therefore, the insertion protrusions 68A, 68B exist in the same plane as the plane in which the base 63 and the arms 64A, 64B exist.

The two insertion projections 68A, 68B are inserted into one hole 49 (see FIGS. 5 and 6) of the type C pole cone 41. As will be described later, when rotating the pole cone 41 to fix it to the ground 10, the insertion protrusion 68A is inserted into the hole 49, and when rotating the pole cone 41 in the opposite direction to remove it from the ground 10, the insertion protrusion 68A is inserted into the hole 49. , the insertion protrusion 68B is inserted into the hole 49. The interval between the insertion protrusions 68A and 68B is larger than the diameter D of the base portion 43 of the pole cone 41.

The two tubes 70 are fixed to intermediate portions of the two arms 64A, 64B, respectively. Specifically, the ends of the tubes 70 can be fixed to the diagonal portions of the arms 64A, 64B by, for example, welding.

The rods 72 of the two sub-components 62 are removably inserted into the two tubes 70, respectively. Each subcomponent 62 has a straight rod 72 and an insertion projection 74 projecting from the end of the rod 72 orthogonally to the rod 72 . Each subcomponent 62 can be formed, for example, by bending a round bar having a uniform diameter along its length. When inserted into the tube 70, the insertion projections 74 of the two sub-components 62 extend parallel to each other.

The two insertion protrusions 74 are inserted into the two holes 29 (see FIGS. 3 and 4) of the type B pole cone 21, respectively. Therefore, the spacing between the insertion protrusions 74 is equal to the spacing G2 between the holes 29.

The rod 72 of each subcomponent 62 is secured to the tube 70 by at least one set screw. In this embodiment, each rod 72 is secured to the tube 70 by two setscrews 76A, 76B, although the number of setscrews is not limited to the embodiment.

As shown in FIG. 11, an arm 64A or 64B is sandwiched between the upper and lower walls of the tube 70. A through hole 77 into which the rod 72 of the subcomponent 62 is inserted is formed in the arms 64A, 64B.

A through hole 78 into which a set screw 76A is inserted is formed in the arms 64A, 64B. Two through holes 80A and 80B are formed in the upper wall of the tube 70, into which two set screws 76A and 76B are respectively inserted, and two through holes 80A and 80B are formed in the lower wall of the tube 70, into which two set screws 76A and 76B are respectively inserted. Screw holes 82A and 82B are formed.

As shown in FIGS. 12 and 13, a plurality of through holes 84 are formed in the rod 72 of the subcomponent 62. As shown in FIGS. In this embodiment, four through holes 84 are formed, but the number of through holes 84 is not limited to the embodiment. Each through hole 84 extends parallel to the insertion protrusion 74 .

Although not essential, the upper surface of the subcomponent 62 is formed as a flat surface 86. Each through hole 84 is orthogonal to the flat surface 86.

The rod 72 inserted into the through hole 77 of the tube 70 and the arm 64A or 64B is movable along the tube 70 and can also be removed from the tube 70 when it is not fixed with the set screws 76A, 76B. It is.

The set screw 76A is inserted into the through hole 80A of the tube 70, the through hole 78 of the arm, or the through hole 84 of the rod 72, and screwed into the threaded hole 82A of the tube 70. The set screw 76B is inserted into the through hole 80B of the tube 70 or the through hole 84 of the rod 72, and screwed into the threaded hole 82B of the tube 70. In this way, the secondary part 62 is fixed to the tube 70 and thus to the main part 61 with set screws 76A, 76B.

By selecting the through holes 84 into which the setscrews 76A and 76B are inserted, the relative position of the sub-component 62 with respect to the main part 61 (that is, the position of the insertion protrusion 74 with respect to the base 63) can be determined as shown in FIGS. 7 and 14. It is possible to adjust. In FIG. 7, the insertion protrusion 74 is the furthest away from the base 63, and in FIG. 14, the insertion protrusion 74 is the closest to the base 63.

As mentioned above, the fastening tool 60 can be used to rotate any of the type A pole cone 1, the type B pole cone 21, and the type C pole cone 41.

When rotating the type A pole cone 1 (see FIGS. 1 and 2), as shown in FIG. Insert into two holes 9 extending in the direction.

The user holds the fastening tool 60 in an appropriate position, for example the base 63, and applies torque to the pole cone 1 via the fastening tool 60. Thereby, the male screw 4 of the pole cone 1 can be rotated. By holding the position away from the insertion protrusion 66 and applying force for rotation, the male screw 4 can be inserted with a small force when installing the pole cone 1 on the ground 10 or when removing the pole cone 1 from the ground 10. It is possible to rotate.

In this case, from the tube 70 so that the rod 72 and/or the insertion projection 74 of the subcomponent 62 does not come into contact with the pedestal 3 (so that the rod 72 and/or the insertion projection 74 do not get in the way of the rotation of the pole cone 1). It is possible to remove the subcomponent 62. Alternatively, as shown in FIG. 14, the position of the subcomponent 62 may be adjusted and the insertion protrusion 74 may be retracted to a position away from the base portion 3.

When rotating the type B pole cone 21 (see FIGS. 3 and 4), as shown in FIG. It is inserted into two holes 29 extending in the direction.

The user holds the fastening tool 60 in an appropriate position, such as the base 63, and applies torque to the pole cone 21 through the fastening tool 60. Thereby, the male screw 4 of the pole cone 21 can be rotated. By holding the position away from the insertion protrusion 74 by the user and applying force for rotation, the male screw 4 can be inserted with a small force when installing the pole cone 21 on the ground 10 or when removing the pole cone 21 from the ground 10. It is possible to rotate.

In this case, in order to facilitate insertion of the insertion protrusion 74 of the sub-component 62 into the hole 29, it is preferable to adjust the position of the sub-component 62 so that the insertion protrusion 74 is as far away from the base 63 as possible.

When rotating the type C pole cone 41 (see FIGS. 5 and 6), as shown in FIG. It is inserted into one radially extending hole 49 formed in the section 43. In this case, the fastening tool 60 is turned over (the insertion projection 66 is directed upward) so that the insertion projection 66 does not contact the ground 10.

The user can insert into the hole 49 the insertion protrusion 68A or 68B that can rotate the male screw 4 with less force. A typical screw tightens when turned clockwise, and loosens when turned counterclockwise. The male screw 4 is a general screw, and when the pole cone 41 is removed from the ground 10 by rotating the male screw 4 counterclockwise, the insertion protrusion 68B is inserted into the hole 49, as shown in FIG. The male screw 4 is a general screw, and when the pole cone 41 is installed on the ground 10 by rotating the male screw 4 clockwise, the insertion protrusion 68A is inserted into the hole 49.

The user holds the fastening tool 60 in an appropriate position, such as the base 63, and applies torque to the pole cone 41 through the fastening tool 60. Thereby, the male screw 4 of the pole cone 41 can be rotated. By having the user hold a position away from the insertion protrusions 68A and 68B and applying force for rotation, the pole cone 41 can be installed on the ground 10 and removed from the ground 10 with a small force. It is possible to rotate the male screw 4.

In this case, the rod 72 and/or the insertion protrusion 74 of the sub-component 62 should not come into contact with the pedestal 43 (so that the rod 72 and/or the insertion protrusion 74 should not get in the way of the rotation of the pole cone 41). The insertion projection 74 may be retracted to a position away from the base portion 43 by adjusting the position of the insertion projection 74 (in this case, not only the insertion projection 66 but also the insertion projection 74 are directed upward). Alternatively, subcomponent 62 may be removed from tube 70.

Second Embodiment First, two types (types D and E) of pole cones with which the fastening tool according to the second embodiment of the present invention can be used will be described.

As shown in FIG. 18, the type D pole cone 91 has a column portion 2, a pedestal portion 93, and a male thread 4.

The pedestal portion 93 is a disk having a larger area than the column portion 2. Although the specific shape and material of the pedestal part 93 are not limited, in one example, the pedestal part 93 is a solid disc made of an elastic material such as polyurethane, and has a small diameter truncated conical upper part 93A and a large diameter part 93A. It has a lower part 93B in the shape of a truncated cone. The lower part of the column part 2 is fixed to the upper part 93A.

As shown in FIG. 19, the upper part of the bolt 8 having the male thread 4 is embedded in the lower part 93B of the pedestal part 93. Therefore, the male screw 4 is firmly fixed to the base portion 93.

Two holes 99 are formed in the lower part 93B. The two holes 99 extend downward from the upper surface of the lower portion 93B of the pedestal portion 93. The two holes 99 are arranged on one straight line orthogonal to the central axis Ax, and the column 2 is arranged between the two holes 99 when viewed from above. A gap G4 is provided between the two holes 99. The spacing G4 is smaller than the spacing G1 between the holes 9 of the type A pole cone 1 and larger than the spacing G2 between the holes 29 of the type B pole cone 21.

The hole 99 penetrates the lower part 93B, but does not have to. Hole 99 is used to rotate pole cone 91 around central axis Ax.

In the above configuration, by rotating the pole cone 91 around the central axis Ax, the male screw 4 can be fastened to the anchor 11 to fix the pole cone 91 to the ground 10. Further, by rotating the pole cone 91 in the opposite direction, the male screw 4 can be taken out from the anchor 11 and the pole cone 91 can be removed from the ground 10.

The male screw 4 is inserted into a metal ring-shaped washer 12. The washer 12 is sandwiched between the bottom surface of the lower part 93B of the pedestal part 93 and the upper part 11B of the anchor 11.

As shown in FIG. 20, the type E pole cone 101 has a column part 2, a pedestal part 103, and a male thread 4. In type E, the diameter of the pillar portion 2 is larger than that in types A to D.

The pedestal portion 103 is a circular plate having a larger area than the column portion 2. Although the specific shape and material of the pedestal part 103 are not limited, in one example, the pedestal part 103 is a solid disc made of an elastic material, for example, polyurethane, and has a small diameter disc-shaped upper part 103A and a large diameter disc-shaped upper part 103A. It has a lower part 103B in the shape of a truncated cone. The lower part of the column part 2 is fixed to the upper part 103A.

Although not essential, a reflective sheet 107 is fixed around the upper portion 103A of the pedestal portion 103.

As shown in FIG. 21, the upper part of the bolt 8 having the male thread 4 is buried in the lower part 103B of the pedestal part 103. Therefore, the male screw 4 is firmly fixed to the base portion 103.

Two holes 109 are formed in the lower part 103B. The two holes 109 extend downward from the upper surface of the lower portion 103B of the pedestal portion 103. The two holes 109 are arranged on one straight line orthogonal to the central axis Ax, and the column 2 is arranged between the two holes 109 when viewed from above. A gap G5 is provided between the two holes 109. The spacing G5 is smaller than the spacing G1 between the holes 9 of the type A pole cone 1 and larger than the spacing G4 between the holes 99 of the type D pole cone 91.

Hole 109 penetrates lower portion 103B, but does not have to. Hole 109 is used to rotate pole cone 101 around central axis Ax.

In the above configuration, the pole cone 101 can be fixed to the ground 10 by fastening the male screw 4 to the anchor 11 by rotating the pole cone 101 around the central axis Ax. Further, by rotating the pole cone 101 in the opposite direction, the male screw 4 can be taken out from the anchor 11 and the pole cone 101 can be removed from the ground 10.

The male screw 4 is inserted into a cylindrical spacer 112 made of resin or metal. The spacer 112 is arranged in the internal space of the upper part 11B of the anchor 11 and is sandwiched between the bottom surface of the lower part 103B of the pedestal part 103 and the lower part 11A of the anchor 11. The spacer 112 may be formed integrally with the pedestal part 103 from the same material as the pedestal part 103.

Next, a fastening tool 120 according to a second embodiment of the present invention will be described with reference to FIGS. 22 to 24. The fastening tool 120 can be used to rotate both the type D pole cone 91 and the type E pole cone 101.

As shown in FIGS. 22 and 23, the fastening tool 120 has a line-symmetrical shape. Fastening tool 120 is made of metal, for example steel. The fastening tool 120 is formed by fixing two round bars 120A and 120B having uniform diameters in the length direction to each other, for example, by welding. The round bars 120A and 120B are bent in the same manner to form a line-symmetrical shape of the fastening tool 120.

The fastening tool 120 has a centrally arranged base 121, a part 122 for the rotation of the type D pole cone 91, and a part 123 for the rotation of the type E pole cone 101.

Portion 122 has two arms 124 and two insertion projections 126.

The two arms 124 extend from one end of the base 121 in directions away from each other. Arm 124 lies in the same plane as base 121. Each of the arms 124 has a diagonal portion connected to and extending obliquely from the base 121, and a tip portion connected to this portion and extending parallel to the base 121.
