Description

  The present invention relates to a road sign post that is detachably mounted on a road surface for vehicle regulation and guidance, and more particularly to a road sign post that allows a display device to be detachably attached to a head.

  When pavement work on roads with heavy traffic, such as national roads in the Tokyo metropolitan area, it may be necessary to restrict some lanes. Due to heavy traffic during the day, such construction is often done at night.

  During construction, barricades, protective fences, road cones, etc. are generally installed on the road surface for the purpose of indicating the construction site or regulating or guiding the vehicle. There is also a method of using a road sign post erected on the road. A plurality of road sign pillars are used to display the outer line and center line of the road or to perform a diversion by standing up and down on the road surface with high visibility. In addition, it has the advantage that it can easily bend and bend, so it has the advantage of less damage to the other party even if it comes into contact with the vehicle etc., so it is also effective for vehicle regulation and guidance during construction. It is believed that there is.

  In addition to the adhesive fixed type that completely fixes the pedestal to the road surface with an adhesive, the road sign post has a bolt at the lower end of the road sign post attached to the embedded leg embedded in the road surface. There is a detachable type that can be detachably attached by screwing while rotating the marker column itself. However, because nighttime work is restricted only at night, it is necessary to remove the road sign pillars from the road surface at the end of each work and reduce the time required for regulation. A detachable road sign post is preferable instead of an adhesive fixed type that cannot be removed.

  By the way, in night construction, since it is necessary to call attention higher than that in daytime, it is necessary to use a display device such as a construction light that flashes and emits light or a reflecting member (Patent Document 1).

  An example of a display device generally used conventionally is shown in FIGS.

  This display device is an example of a construction light 10 and includes a construction light main body 11 in which a light emitting unit (not shown) made of an LED or the like is accommodated, and a cylindrical tube provided at the lower end of the construction light main body 11. It consists of a body 12. In general, the cylindrical body 12 is made of synthetic resin, and two protrusions 13 and 14 that protrude in a rectangular shape are integrally formed on the outer peripheral surface of the cylindrical body 12 so as to be divided into a lower side and an upper side. The position of the lower protrusion 13 around the axis of the cylindrical body 12 is arranged at a position rotated 90 ° counterclockwise with respect to the upper protrusion 14 in a plan view as viewed from above the construction lamp main body 11.

  The case where the construction lamp 10 is attached to the top of the load cone will be described. As shown in FIG. 9, the upper end surface 101 of the load cone 100 is formed flat, and the outer diameter of the cylindrical body 12 of the construction lamp 10 is A mounting hole 102 having the same or slightly larger diameter is provided. A key groove 103 into which the lower protrusion 13 and the upper protrusion 14 of the cylindrical body 12 can be inserted is formed along a part of the periphery of the attachment hole 102 along the axial direction (vertical direction) of the attachment hole 102. .

  When mounting the construction lamp 10 in the mounting hole 102 of the load cone 100, first, the cylindrical body 12 is inserted into the mounting hole 102 so that the lower protrusion 13 of the cylindrical body 12 is fitted in the key groove 103. When the lower projection 13 comes out below the keyway 103 (FIG. 10A), the construction lamp 10 is rotated 90 ° counterclockwise to fit the upper projection 14 into the keyway 103, and the construction lamp The main body 11 is further pushed downward until the lower end edge 11a of the main body 11 contacts the upper end surface 101 of the load cone 100 (FIG. 10B). The construction lamp 10 thus mounted on the load cone 100 is prevented from coming off from the mounting hole 102 by the lower projection 13 and is prevented from rotating by the upper projection 14 engaging the key groove 103. The

  Therefore, when the display device is attached to the road sign post, it is convenient if the display device can be attached by providing the same mounting hole and keyway as the above in the head of the sign post main body.

JP 2006-112085 A

  However, when such a display device is attached to a road sign post, there are the following problems specific to the road sign post.

  The display device needs to be installed so as to face in an appropriate direction in order to be able to effectively prompt attention when performing vehicle regulation and guidance during night construction. In the case of a load cone that is only placed on the road surface, the display device can be easily set to an appropriate orientation by freely adjusting the direction of the load cone itself, but the embedded leg embedded in the road surface In the case of a road sign post erected so as to be detachable by screwing to the part, the direction around the axis of the road sign post at the time of screwing is determined by the combination with the embedded leg part. The orientation of the display device attached to the head is also determined. In other words, with a combination of a certain road sign post and embedment leg, even if the orientation of the display device is in the proper direction for vehicle regulation and guidance, the road sign post is put on another place on the road surface. If it is attached to the embedded leg, the display device may not be oriented in the proper direction.

  For this reason, even if it is a road sign pillar that is erected on the road surface so that the orientation of the display device is an appropriate orientation, if it is removed from the embedment leg every time night work is completed, When it is combined with another embedment leg when starting the night work, there is a problem that the direction of the display device is different and proper regulation and guidance of the vehicle cannot be performed.

  Such a problem can be solved by putting a number on the road sign pillar in advance and combining it with the same embedment leg every time, but it is a very time-consuming work and limited. This is not a realistic solution for night work that requires work within the time limit.

  It is also conceivable that the upper projection 14 can be rotated without being engaged with the key groove 103 so that the display device can be directed in an arbitrary direction. In order to reduce the damage caused when contacting with vehicles, etc., the whole can be flexed elastically. The side is easy to swing, and the vibration generated at that time may cause the display device to face in an unintended direction, which is not a realistic solution.

  In this way, when providing a display device at the head of the road sign post, not to be easily detached when it comes into contact with the vehicle, etc., of course, after standing the road sign post, It is required to solve the conflicting problem that the display device can be directed in an arbitrary direction and the display device is not directed in an unintended direction.

  Therefore, the present invention can removably attach the display device to the head of a road sign post that is attached to the embedment leg embedded in the road surface and attach the display device in any direction around the axis. It is an object of the present invention to provide a road sign pillar that can be directed and can maintain its direction.

  Other problems of the present invention will become apparent from the following description.

  The above problems are solved by the following inventions.

(Claim 2)
2. The road sign post according to claim 1, wherein the head is formed separately from the sign post main body, and is fixed to an upper end of the sign post main body.

  According to the present invention, the display device can be detachably attached to the head of the road sign post that is attached to the embedment leg embedded in the road surface, and the display device can be mounted in any direction around the axis. It is possible to provide a road sign pillar that can be directed and maintained in its direction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of a road sign post according to the present invention. The road sign post 1 has a base 3 that is slightly larger in diameter than the sign post main body 2 fixed to the lower end of a cylindrical sign post main body 2. And a cap-like head 4 is fixed to the upper end.

  The sign post body 2 is generally formed in a hollow cylindrical shape having upper and lower ends opened with flexible polyurethane resin such as polyurethane elastomer, and an outer peripheral surface on the upper side thereof is appropriately arranged to alert the driver. A number of retroreflective sheets 5 are wound.

  One mounting bolt 6 projects downward from the center of the lower end of the pedestal 3. The head (not shown) of the mounting bolt 6 is integrally attached to the pedestal 3, and the road marking column 1 attaches the mounting bolt 6 to the female screw of the embedded leg 7 embedded in the road surface in advance. The sign post main body 2 itself is screwed while rotating, so that it is attached to the burying leg 7 and is erected on the road surface. Such mounting structures and methods are known.

  The head 4 is formed of a synthetic resin separately from the sign post body 2, is attached so as to cover the upper end opening 2 a of the sign post body 2, and is integrally fixed by an adhesive. By forming the head 4 separately from the sign post body 2 in this way, the existing sign post main body 2 can be used as it is, so only the head part is changed in the existing manufacturing process. Thus, the manufacturing cost can be reduced, and the display device can be easily modified to be detachable from the existing road sign post.

  Details of the head 4 are shown in FIG. 2A is a plan view of the head 4 and FIG. 2B is a cross-sectional view.

  The upper end surface 4a of the head 4 is formed as a flat surface, and a circular recess 4b is formed in the center thereof. The inner diameter of the recess 4b is the same as or slightly larger than the outer diameter of the cylindrical body 12 including the lower protrusion 13 and the upper protrusion 14 that are provided to protrude from the cylindrical body 12 of the display device (construction lamp 10) shown in FIG. It is formed to become. A circular standing wall portion 4c rising from the bottom surface of the recess 4b is formed by the recess 4b.

  At the center of the recess 4b, there is a circular mounting hole 4d having the same or slightly larger outer diameter than the lower protrusion 13 and the upper protrusion 14 of the cylindrical body 12. The mounting hole 4d has a size that allows the cylindrical body 12 to pass through, but does not allow the upper projection 14 and the lower projection 13 to pass therethrough, and is formed concentrically with the standing wall 4c. Yes. The specific diameter is determined by the outer diameter of the cylindrical body 12 of the display device to be mounted.

  The mounting hole 4d extends in the thickness direction of the head 4 and is formed so as to penetrate the head 4. The axial length L1 of the mounting hole 4d is set to L2 (FIG. 8) as the axial distance between the lower end of the upper projection 14 formed on the cylindrical body 12 and the upper end of the lower projection 13. At this time, L1 ≦ L2.

  A part of the peripheral edge of the mounting hole 4d has a key groove 4e into which the lower protrusion 13 can be inserted when the cylindrical body 12 is inserted into the mounting hole 4d and inserted in the axial direction of the mounting hole 4d. It is formed along (vertical direction). Similarly to the mounting hole 4d, the key groove 4e extends in the thickness direction of the head 4 and is formed so as to penetrate the head 4. The axial length of the key groove 4e is the length of the mounting hole 4d in the axial direction. It is the same as L1.

  On the inner peripheral surface of the upright wall portion 4c, a large number of convex portions 4f are integrally projected at a predetermined height toward the center except for a portion where the key groove 4e is disposed. Although the convex part 4f shown in this embodiment has shown the preferable aspect formed by the protruding item | line extended along the height direction of the standing wall part 4c, it has protruded in at least one part of the height direction of the standing wall part 4c. That's fine.

  The convex portions 4f are arranged at regular intervals along the inner peripheral surface of the standing wall portion 4c except for the portion where the key groove 4e is arranged. This space | interval is set to the space | interval which can be mutually engaged by the upper side protrusion 13 of the cylindrical body 12 fitting between adjacent convex parts 4f and 4f. In the present embodiment, except for the portion where the key groove 4e is arranged, a total of ten convex portions 4f are formed by shifting by 30 ° in the circumferential direction with respect to the center (θ = 30 °). The angle θ is appropriately determined according to the width of the upper protrusion 14.

  Next, a method of mounting the construction lamp 10 shown in FIG. 8 on the head 4 of the road sign pillar 1 will be described with reference to FIGS.

  3 is a cross-sectional view showing a portion of the head 4 of the road sign pillar 1, and FIG. 4 is a plan view.

  First, the cylindrical body 12 is inserted into the mounting hole 4d so that the lower protrusion 13 of the cylindrical body 12 is fitted in the key groove 4e (FIGS. 3A and 4A).

  When pushed down as it is, the upper protrusion 14 comes into contact with the bottom surface (upper surface) of the recess 4b, and further pushing is prevented. Since L1 ≦ L2, at this time, the lower protrusion 13 protrudes from the lower end of the key groove 4e.

  When the upper projection 14 comes into contact with the bottom surface of the recess 4b, the construction lamp main body 11 is rotated about its axis so that the construction lamp main body 11 is in a desired direction. Here, the construction lamp main body 11 is shown rotated 90 ° clockwise in plan view, but the rotation angle may be arbitrary as long as the upper protrusion 14 does not coincide with the key groove 4e.

  Due to this rotation, the cylindrical body 12 is also integrally rotated around the axis, so that the lower protrusion 13 is located below the position of the key groove 4e below the mounting hole 4d (FIG. 3 (b), FIG. 4 ( b)). As a result, the construction light 10 is prevented from coming off, and even if a vehicle or the like comes into contact with the road sign pillar 1, the construction light 10 is prevented from being separated and scattered.

  During this rotation, the upper protrusion 14 rotates in the circumferential direction on the inner side of the standing wall 4c. At this time, the tip of the upper protrusion 14 is in contact with each convex portion 4f protruding from the inner peripheral surface of the standing wall portion 4c and elastically climbs over the convex portions 4f one after another. ”And rotate. Since each convex part 4f is rounded at the tip, the upper protrusion 14 can be smoothly and elastically overcome.

  The upper projection 14 overcoming the convex portion 4f is fitted between the adjacent convex portions 4f and 4f at the position where the construction lamp main body 11 is in a desired direction, and is engaged between the convex portions 4f and 4f. Thereby, the road sign pillar 1 with the display device (construction lamp 10) in which the construction lamp 10 is arranged in a desired direction is obtained (FIG. 5).

  The direction of the construction lamp 10 is held at a position where the upper projection 14 is engaged between the adjacent convex portions 4f and 4f, and the upper projection 14 does not apply a forcible rotational force that elastically climbs over the convex portion 4f. Since it does not rotate as much as possible, there is no problem that the construction lamp 10 is directed in an unintended direction due to vibration or the like. Therefore, according to the road sign pillar 1, the vehicle can be safely regulated and guided during construction by the display device attached to the head 4 thereof.

  In the present invention, the display device is a device that urges a vehicle or a person to call attention or displays information. The display device is not limited to the flashing construction light 10 described above, and is exemplified below. It may be.

  FIG. 6 shows a display device comprising a reflector 20 used as a so-called delineator. By attaching the reflector main body 21 to the upper end of the cylindrical body 12 having the lower protrusion 13 and the lower protrusion 14, the head 4 of the road sign pillar 1 can be arbitrarily attached in the same manner as in the case of the construction light 10. It can be detachably attached so as to be oriented.

  FIG. 7 shows a display device including a display board 30 displaying characters and figures. By attaching the display panel main body 31 to the upper end of the cylindrical body 12 having the lower protrusion 13 and the lower protrusion 14, the head 4 of the road sign post 1 can be arbitrarily attached to the head 4 of the road sign pillar 1. It can be detachably attached so as to be oriented.

  According to the road sign pillar 1 according to the present invention, these various display devices can be used in appropriate combination during the construction period according to the standing place of the road sign pillar 1, the regulation, and the purpose of guidance.
