[Technical Field]

[0001] The present invention relates to a delineator connector for a road sign, which is used to connect a delineator to a road sign as needed. [Background technology]

[0002] When traffic restrictions are implemented for a certain period of time, it is sometimes necessary to install road signs for a specified period of time, and in such cases, mountain-shaped signboards are used, such as those described in Patent Document 1. These mountain-shaped signboards have arrows displayed on them and are placed on roads etc. to guide passing vehicles in the direction indicated by the arrows. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-218332 Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, delineators are used on roads, parking lots, facilities where vehicles enter and exit, and other areas to support driving by guiding the driver's line of sight. Conventionally, delineators have been installed separately from road signs, with the support poles set underground (in the ground) or in concrete, or the base plates fixed to the concrete surface with anchor bolts. However, if delineators can be integrated with road signs, it would be preferable because it would reduce the component that occupies a part of the road landscape.

[0005] The present invention was made in response to the above-mentioned conventional problems, and its purpose is to provide a new and useful delineator connector for road signs that can be detachably attached to mountain-shaped signboard-type road signs and used to connect delineators. [Means for solving the problem]

[0006] The present invention has been made to solve the above problems, and is a road sign delineator connector for connecting a delineator to a mountain-shaped sign board that forms a road sign, a folded plate body formed by bending a plate and having a rectangular upper surface portion, a pair of inclined flaps connected to both left and right sides of the upper surface portion to form a V-shape, and a fold-in flap connected to the front side of the upper surface portion and having a lower surface portion with its tip side parallel to the upper surface portion, with a female hole provided on the lower surface portion; a cylindrical socket fitting portion connected to the upper surface of the upper surface portion and into which a delineator socket is fitted from above; a bolt that is inserted into the female hole with its head facing downward so as to be able to threadably advance and retreat; and the socket. This is a delineator connector for road signs, characterized in that it is provided with a releasable locking means on the inner fitting side that locks the socket while it is fitted into the socket inner fitting portion, and the top of the mountain-shaped sign board is inserted relatively between the upper and lower surfaces of the folded plate body, is pressed against the shaft end side of the bolt and the upper surface, and is fixed to the mountain-shaped sign board while being pressed from above by the inclined flap, thereby making the delineator connectable to the mountain-shaped sign board.

[0007] Preferably, the pressure contact side of the bolt is configured as a sphere. More preferably, the crimp side of the bolt comprises a plastic grip. Preferably, rising flaps are further connected to both left and right sides of the lower surface of the fold-in flap.

[0008] Preferably, the socket fitting portion is cylindrical and is provided in a positional relationship where it is coaxial with the axis of the bolt. More preferably, the locking means is composed of an L-shaped slit extending from the upper edge of the socket fitting portion, and is locked by a locking protrusion protruding from the outer surface of the socket on the delineator side engaging with the slit at a position where it cannot move vertically. [Effects of the Invention]

[0009] By using the road sign delineator connector of the present invention, the delineator can be easily connected in the correct position to road signs such as mountain-shaped signs. [Brief explanation of the drawings]

FIG. [Figure 3] FIG. 3 is a side view of FIG. 2. [Figure 4] 3 is a side view of the road sign delineator coupler of FIG. 2 in two directions perpendicular to each other at the installation location, with some of the surface portions made transparent. DETAILED DESCRIPTION OF THE INVENTION

[0011] As shown in Figure 2, the mountain-shaped sign A, which forms a road sign, is made of aluminum and is made by bending the plate into an acute mountain shape. The outer surfaces of the two inclined surfaces a2 on either side of the top a1 are display surfaces with arrows drawn on them. When traffic restrictions are in place, the sign is placed on the road in an upright position with the top a1 at the top, and guides passing vehicles in the direction indicated by the arrows. The air hole a3 is hexagonal. A road sign delineator connector 1 according to an embodiment of the present invention is fixed to the mountain-shaped sign board A thus installed.

[0012] The configuration of the road sign delineator coupler 1 will be described in detail below with reference to FIGS. The road sign delineator connector 1 is made of aluminum. Reference numeral 3 denotes a folded plate body formed three-dimensionally by bending a plate. This folded plate body 3 is composed of a combination of multiple flat surfaces, and will be described based on the up-down, front-rear, left-right directions with the rectangular top surface 5 shown in Figures 3 and 4(2) as the reference. Rectangular inclined flaps 7, 7 are connected to the left and right sides of the top surface portion 5 over almost the entire length. The left and right sides are each folded, and the plate surface of the inclined flap 7 is inclined diagonally downward relative to the plate surface of the top surface portion 5. The pair of inclined flaps 7, 7 are symmetrical, and form the shape of the Japanese character "V" when viewed from the front to back.

[0013] Additionally, a rectangular fold-in flap 9 extends along almost the entire length of the front edge of the top surface portion 5. The front edge is a bent portion, and the base end surface of the fold-in flap 9 is perpendicular to the surface of the top surface portion 5. The fold-in flap 9 is further bent in the folding direction midway. The tip end surface is parallel to the surface of the top surface portion 5 and wraps around to the underside of the top surface portion 5, forming the under surface portion 11. Furthermore, rectangular rising flaps 13, 13 are connected to the left and right sides of the lower surface portion 11 over almost the entire length. The left and right sides are bent portions that are bent vertically and rise up, with the respective plate surfaces facing each other.

[0014] The upper surface portion 5 and the lower surface portion 11 are approximately the same size. A gap is formed in the vertical direction between the lower edge of each of the pair of inclined flaps 7, 7 and the upper edge of each of the rising flaps 13, 13, and the space is open in the left-right direction via this gap. The lower edge of the inclined flap 7 is located outward in the left-right direction from the upper edge of the rising flap 13.

[0015] A round through-hole penetrates the center of the underside 11, and a reinforcing ring is attached to the edge of the hole. A nut 15 is attached coaxially above the hole, and this configuration forms a female hole 17 that penetrates the underside 11 in the vertical direction. A shaft 19b of the knob bolt 19 is inserted into this female hole 17 with the knob 19a of the knob bolt 19 facing downward, and is screwed onto the nut 15. The tip of the shaft 19b is embedded in and integrated with the sphere 21. The sphere 21 is made of a plastic grip, and its center is located on the axis of the shaft 19b. In the road sign delineator connector 1, only the sphere 21 is made of plastic. The sphere 21 is sized to fit within the upper surface portion 5 and the lower surface portion 11, and is disposed between the upper surface portion 5 and the lower surface portion 11, and moves up and down as the nut 15 is threaded forward and backward.

[0016] A socket fitting portion 23 is provided adjacent to the upper surface portion 5 of the folded plate body 3 . This socket fitting portion 23 has a straight cylindrical shape, and one axial end edge is welded and fixed to the center of the upper surface portion 5. Therefore, the socket fitting portion 23 is positioned coaxially with the axis 19b of the knob bolt 19 that is inserted therethrough. A slit 25 that penetrates the wall thickness of the tubular portion and is open to the inside and outside in the circumferential direction is formed in the socket inner fitting portion 23. This slit 25 extends straight downward from the upper end edge, then changes direction at a right angle around the middle and extends horizontally, with the vertical slit 25a and horizontal slit 25b continuing together to form an L shape overall.

[0017] The road sign delineator connector 1 is configured as described above, and can be connected to a delineator D. A delineator has a pole on the upper side of the fixed side, which is installed underground or on a concrete surface or fixed to a base plate, and a reflector that reflects light is attached to the top of this pole. In the delineator D, which is intended to be attached integrally to the road sign delineator connector 1, the reflector d1 is composed of a reflector plate inside a square cylindrical case with a top and a solar panel on its top. A battery box is fixed to a holder d2 attached to the underside of the reflector d1. The holder d2 has a cylindrical shape, partially cut along a plane parallel to the axial direction, but approximately three-quarters of a circle remains when viewed from the axial direction. The holder d2 and reflector d1 are connected coaxially, with the outer periphery of the holder d2 having a smaller diameter than the outer surface of the reflector d1, creating a step at the boundary between them. A convex locking projection d3 is provided on the arcuate outer peripheral surface of the holder d2.

[0018] This Delineator D is sold by T-Cube Co., Ltd. as the "Santo Moon Solar Construction Light TCS-88RG." However, it is recommended that it be installed by inserting it into a cut cone. The dimensions of the socket internal fitting portion 23 are designed to fit this type, and the holder d2 is fitted inside. At that time, the locking protrusion d3 is slidably fitted into the slit 25 with a loose fit, so the holder d2 is fitted inside within the range where the locking protrusion d3 can move within the slit 25.

[0019] The holder d2 is inserted and fitted into the socket fitting portion 23 while the locking protrusion d3 on the holder d2 side of the delineator D slides into the slit 25 on the socket fitting portion 23 side. Because the reflector d1 has a larger diameter than the holder d2, when the underside of the reflector d1 abuts against the upper edge of the socket fitting portion 23, it cannot be inserted any further and is inserted as far as possible and fitted in. At this time, the locking protrusion d3 passes through the vertical slit 25a and reaches the horizontal slit 25b, and when the holder d2 is further rotated circumferentially relative to the socket fitting portion 23 and abuts against its inner end, the holder d2 is locked in an attached state where it cannot move axially relative to the socket fitting portion 23.

[0020] For ease of viewing, Figure 4(1) is a side view in which the inclined surface portion a2, inclined flap 7, and rising flap 13 that are located in front of the mountain-shaped display board A from the installation point of the road sign delineator connector 1 are made transparent, and Figure 4(2) is a side view in which the plate surface portion on the base end side of the fold-in flap 9 is made transparent from the installation point of the road sign delineator connector 1.

[0021] After connecting the delineator D as described above, the road sign delineator connector 1 is fixed to the mountain-shaped sign board A, whereby the delineator D is indirectly connected to the mountain-shaped sign board A. Specifically, the top a1 of the mountain-shaped display board A is sandwiched between the upper surface 5 of the folded plate body 3 and the sphere 21 protruding from the lower surface 11, so that the top a1 is relatively inserted between the upper surface 5 and the sphere 21. Thereafter, the shaft 19b of the knob bolt 19 is screwed forward, and the sphere 21 presses against the top portion a1, thereby bringing the top portion a1 into a pressure-contact state with the upper surface portion 5.

[0022] The radius of curvature of the sphere 21 is set to be smaller than the radius of curvature of the apex a1, so that the sphere 21 reliably contacts the inner surface of the apex a1. In addition, the lower edges of the inclined flaps 7 press down on the inclined surface portions a2 from above. The road sign delineator coupler 1 is fixed with the socket fitting portion 23 in an upright position on the apex a1, and this fixed state is stably maintained. Therefore, if the mountain-shaped sign A is placed on the road or the like in an upright position with the apex a1 at the top, the reflector d1 of the delineator D will automatically face sideways.

[0023] The dimensional relationship between the mountain-shaped sign board A and each part of the road sign delineator connector 1 is shown in Figures 2 and 3, and the mountain-shaped sign board A used is one with dimensions of x: 700 mm, y: 700 mm, z: 600 mm. The socket fitting portion 23 has an outer diameter of 45 mm, a thickness of 2 mm, and a length of 80 mm, and the knob bolt 19 is an M10 knob bolt.

[0024] The work of connecting the delineator D to the road sign delineator connector 1 and the work of fixing the road sign delineator connector 1 to the mountain-shaped display board A can be easily performed on site. Furthermore, in the above example, the operation of connecting the delineator D to the road sign delineator connector 1 is performed first, but the order can also be reversed.

[0025] The above describes in detail the embodiment of the present invention, but the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are also included in the invention. For example, the road sign delineator connector 1 can be made of a material other than aluminum, such as stainless steel or synthetic resin. The size and orientation of each part of the road sign delineator connector 1 can be optimized appropriately to match the actual angle of the top a1 of the mountain-shaped display board A so that the sphere 21 is in secure contact with the inner surface of the top a1 and the lower edges of each of the inclined flaps 7, 7 press down on the inclined surface parts a2, a2 ​​from above, as described above.
