Description

[Technical Field]

[0001] The present invention relates to a bollard used to prevent vehicle intrusion. [Background technology]

[0002] Conventional bollards have been disclosed that consist of a pillar-shaped car stopper body (core material) that is installed vertically in the ground, and multiple pieces of cover that can be individually and detachably attached around the car stopper body, so that the entire support post does not need to be replaced if it is damaged by a collision with a vehicle or the like (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-302633 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the bollard described in Patent Document 1, the cover is fixed to the core material with bolts, and bolt holes must be formed in the core material, which limits the specifications of the core material and makes it difficult to use existing bollards as core materials.

[0005] The present invention was made with an eye on such problems, and aims to provide a bollard that has a high degree of freedom in the specifications of the core material and can be easily used as the core material of existing bollards. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the bollard of the present invention is characterized in that it comprises a core material, a pair of frame materials, band fittings, and fixing members, the core material having an elongated shape and standing upright on the ground, the pair of frame materials sandwiching the sides of the core material, and the band fittings sandwiching the core material between each frame material and being detachably attached to each frame material by the fixing members.

[0007] The bollard of the present invention has a pair of frame materials that sandwich the sides of a core material, and band fittings that sandwich the core material between each frame material and are removably attached to each frame material by fixing members.Since no specifications are required to fix the frame materials to the core material, there is a high degree of freedom in the specifications of the core material, and it is also easy to use existing bollards as core materials.

[0008] In the bollard of the present invention, it is preferable that the pair of frame materials are arranged with a gap between them on the sides, and that a lighting device that diffuses indirect light to the outside from the gap is provided inside the frame materials. In this case, it can be used as an indirect lighting device, and can also be used as a street light or an object. Also, the lighting device can improve visibility at night.

[0009] In the bollard of the present invention, it is preferable that the lighting device has a light source and a reflector, the light source is attached to the reflector, and the reflector is attached to the inside of the frame material so as to diffuse indirect light from the light source to the outside through the gap. In this case, the light source of the lighting device is attached to a reflector, which is then attached to the frame material, so that the light source is less likely to scatter in the event of a vehicle collision, and safety is increased. In addition, the reflector can improve illuminance.

[0010] In the bollard of the present invention, it is preferable that the core material has a main body and a lid, the main body has a storage compartment inside, the lid is attached to the top of the main body so as to be able to open and close the storage compartment, the frame material has frame side portions and frame top portions, the frame side portions are attached along the sides of the main body, and the frame top portions are attached to cover part of the top surface of the lid, the frame material and the band fittings are attached above the core material so as to be removable when the fixing member is loosened, the light source is driven by electricity, and a light source driver for driving the light source is attached to the bottom of the lid and housed in the storage compartment.

[0011] In this case, the light source driver for the electrically powered light source is attached to the lower part of the lid of the core material and housed in the housing, and the light source driver can be removed from the housing by removing the lid from the main body, making it easy to repair or replace the light source driver. The frame material covers the sides of the main body with the frame side parts and covers part of the top surface of the lid with the frame upper part, so the core material can be protected from the sides and top. The frame material can be removed forward from the core material by removing the fixing members, and can also be removed upward from the core material together with the metal band with the fixing members loosened, making it easy to maintain or repair the core material and the light source driver housed in the core material.

[0012] The bollard of the present invention preferably has a sheath pipe, which is tubular and has at least its lower part underground and an insertion opening at its upper part, and the lower end of the core material is removably inserted into the insertion opening. In this case, the core material can be pulled out from the insertion opening of the sheath tube to allow vehicles to pass through. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a bollard that has a high degree of freedom in the specifications of the core material and can be easily used as a core material for existing bollards. [Brief explanation of the drawings]

[0015] Various embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a bollard according to a first embodiment of the present invention. As shown in FIGS. 1 to 4, the bollard of the first embodiment has a core material 1, a pair of frame materials 2A and 2B, a metal band 3, a fixing member 4, and a lighting device 5.

[0016] The core material 1 is a prefabricated H-shaped bollard and has a body 11 and a lid 12. The body 11 has a long, thin cylindrical shape. The body 11 has a storage section 13 inside. The lid 12 is disk-shaped and is screwed onto the top of the body 11 to open and close the storage section 13. The lid 12 is connected to the body 11 with a wire to prevent it from flying off in the event of a vehicle collision, etc. The bottom of the core material 1 is inserted into a vertical hole 6 formed in the ground and installed upright. The bottom of the core material 1 is fixed underground with bolts to a concrete foundation 7. Crushed roadbed stone 8 is laid on top of the foundation 7, and asphalt 9 is laid on top of that.

[0017] Each frame member 2A, 2B is made of wood or resin and integrally comprises a frame side portion 21 and a frame upper portion 22. The frame side portion 21 has a width greater than the diameter of the core member 1 and a length approximately equal to the length of the core member 1 protruding above ground, and is provided along the side of the main body 11. The frame side portion 21 has a pair of through-holes at the top and bottom that extend in the thickness direction. The pair of through-holes are spaced apart in the width direction of the frame side portion 21 and parallel to each other, sandwiching the main body 11 between them. The frame upper portion 22 extends perpendicular to the upper end of the frame side portion 21 and is provided to cover part of the top surface of the lid 12. The outer surfaces of the pair of frame members 2A, 2B are parallel to each other, sandwiching the sides of the core member 1. The pair of frame members 2A, 2B are arranged with a gap between them on the sides. Various designs may be applied to the outer surfaces of the frame members 2A, 2B.

[0018] As shown in Figures 2(B) and 3(A), the band metal fitting 3 has a long Ω-shaped metal fitting 31 and a short Ω-shaped metal fitting 32. The long Ω-shaped metal fitting 31 and the short Ω-shaped metal fitting 32 have an arc-shaped curved portion that follows the circumferential surface of the main body 11 and both end portions that are flat. Both end portions have mounting holes in the thickness direction. The arc-shaped curved portion of the short Ω-shaped metal fitting 32 is shorter than that of the long Ω-shaped metal fitting 31. The long Ω-shaped metal fitting 31 has both end portions detachably attached to the frame materials 2A, 2B by fixing members 4, with the main body 11 sandwiched between the long Ω-shaped metal fitting 31 and the frame materials 2A, 2B.

[0019] The short Ω-shaped metal fitting 32 is positioned along the main body 11 on the side of the frame members 2A and 2B, with both ends detachably attached to the frame members 2A and 2B by fixing members 4. The mounting positions of the band metal fittings 3 on the main body 11 are provided with projections or grooves to prevent the metal fittings from slipping, ensuring safety. The fixing members 4 consist of bolts and nuts. The bolts pass through through holes from the outside of the frame members 2A and 2B and through mounting holes at both ends of the long Ω-shaped metal fitting 31 or the short Ω-shaped metal fitting 32, and are detachably screwed into the nuts on the inside of the frame members 2A and 2B. As shown in Figure 2(B), the bolt heads and nuts are housed in recesses 14 formed in the frame members 2A and 2B.

[0020] The band metal fittings 3 are attached to the core material 1 at two points, one above the other, and one frame material 2A is attached to the core material 1 at two points, one above the other. The other frame material 2B is similarly attached to the core material 1 at two points, one above the other, offset from the one frame material 2A.

[0021] As shown in Fig. 2(C), the lighting device 5 has a light source 51 made up of an LED module and a reflector 52. The light source 51 is attached to the reflector 52, which is attached to the inside of the frame members 2A and 2B. The light source 51 diffuses indirect light from the gap between the frame members 2A and 2B to the outside. The reflector 52 diffuses the indirect light from the light source 51 from the gap between the frame members 2A and 2B to the outside.

[0022] A light source driver (power supply) 53 for driving the light source 51 is attached to the bottom of the lid 12 and housed in the housing 13. A U-shaped groove 15 is formed at the top end of the main body 11 of the core material 1, and an electric cable extending from the light source driver 53 passes through the U-shaped groove 15 and is connected to the light source 51. This improves the ease of feeding and pulling out the cable when attaching and detaching the lid 12 and the light source driver 53. The light source driver 53 is connected to an electric cable that runs through the inside from the bottom of the main body 11. A ventilation hole 16 is formed in the main body 11, and a breathable sheet for preventing foreign matter from entering the ventilation hole 16 is attached to the ventilation hole 16.

[0023] In the first embodiment of the bollard, a pair of frame materials 2A, 2B sandwich the sides of a core material 1, and band fittings 3 sandwich the core material 1 between each of the frame materials 2A, 2B and are removably attached to each of the frame materials 2A, 2B by fixing members 4.As there is no need for specifications to directly fix the frame materials 2A, 2B to the core material 1, there is a high degree of freedom in the specifications of the core material 1, and it is also easy to use existing bollards as the core material 1.

[0024] The bollard of the first embodiment can be used as an indirect lighting device, and can also be used as a street light or an object. Furthermore, the lighting device 5 can improve visibility at night. The light source 51 of the lighting device 5 is attached to a reflector 52, and is attached to the frame members 2A and 2B via the reflector 52, so that the light source 51 is less likely to fly off in the event of a vehicle collision, thereby improving safety. Furthermore, the reflector 52 can improve illuminance.

[0025] In the bollard, the light source driver 53 for the electrically powered light source 51 is attached to the bottom of the lid 12 of the core material 1 and housed in the housing 13. The light source driver 53 can be removed from the housing 13 by removing the lid 12 from the main body 11, making it easy to repair or replace the light source driver 53. When installing an LED light source driver inside a street light, it is common to provide a large-diameter opening to install the light source driver. In contrast, the bollard of this embodiment does not require a large-diameter opening, and the light source driver 53 is attached to the bottom of the lid 12 and housed in the core material 1, so the strength of the core material 1 is not sacrificed.

[0026] Frame members 2A and 2B cover the sides of main body 11 with frame side portions 21 and cover part of the top surface of lid 12 with frame upper portion 22, so that core member 1 can be protected from the sides and from above. Frame members 2A and 2B can be removed toward the front from core member 1 by removing fixing members 4, and can also be removed upward from core member 1 together with band metal fittings 3 with fixing members 4 loosened, which facilitates maintenance or repair of core member 1 and light source driver 53 housed in core member 1.

The band metal fitting 30 has a short Ω-shaped metal fitting 301 and a U-shaped metal fitting 302.

[0028] The short Ω-shaped metal fitting 301 has an arc-shaped curved portion that follows the circumferential surface of the main body 11 and both flat end portions. Both end portions have mounting holes in the thickness direction. The short Ω-shaped metal fitting 301 is arranged along the main body 11 on the frame material 20A side, and both end portions are fixed to the frame material 20A with screws. The U-shaped metal fitting 302 has mounting holes on both ends. One end of the U-shaped metal fitting 302 is attached to the short Ω-shaped metal fitting 301 by a fixing member 40.

[0029] The fixing member 40 consists of a stud bolt and a nut, and the stud bolt passes through an attachment hole in the short Ω-shaped metal fitting 301 and is detachably screwed into the nut on the inside of the U-shaped metal fitting 302. A similar short Ω-shaped metal fitting 301 is fixed to the other frame member 20B, and the other end of the U-shaped metal fitting 302 is attached to the short Ω-shaped metal fitting 301 on the other frame member 20B side. In this way, the band metal fittings 30 are detachably attached to each of the frame members 20A, 20B by the fixing members 40, with the core material 1 sandwiched between them. The band metal fittings 30 are attached to the core material 1 at two locations, one above and one below, and the pair of frame members 20A, 20B are attached to the core material 1 at two locations, one above and one below. The bollard of the second embodiment has an appearance in which the bolts are not visible on the outer surface.
