Description

The present invention relates to a light emitting body, and more particularly to a light emitting body installed on an upper part of a pillar such as a line-of-sight guide pillar.

It is known to install columns such as line-of-sight guide pillars to indicate the median strip of the roadway, the center line, the lane change line, the prohibition of vehicle entry, and the boundary line between the roadway and other roads.

For example, in Patent Document 1, a reflective sheet having a first color tone (for example, red) and a reflective sheet having a second color tone (for example, green) are arranged around a pole body having a white color tone under sunlight. The line-of-sight guide pillars that are tightly wrapped around are described. According to Patent Document 1, by configuring as described above, excellent visibility can be exhibited both in the daytime and at night.

Further, for the purpose of increasing visibility, a light emitting body may be installed on the upper part of a support such as a line-of-sight guide pillar as described above.

For example, Patent Document 2 describes a light emitting sign device installed on an upper part of a pillar such as a line-of-sight guide pillar. Specifically, the light emitting marking device in Patent Document 2 covers the lower holder attached to the support, the casing attached to the lower holder, the upper holder attached to the upper part of the casing, and the entire upper surface of the upper holder. It has a light emitter cover that can be attached. According to Patent Document 2, the substrate to be fixedly instructed between the upper holder and the illuminant cover has a frame shape provided with a notch. With such a configuration, it is possible to obtain a lamp body with visibility similar to that provided with a large number of light emitting diodes with a small number of light emitting diodes.

In the present embodiment, as shown in FIG. 1, for the line-of-sight guide pillar 4 (post cone, support) installed above the line-of-sight guide pillar 4 (post cone, pillar) installed to show a boundary line such as a median strip of a roadway. The light emitting body 1 (light emitting body) will be described. As will be described later, the line-of-sight guidance pillar light emitter 1 is the second upper end side of the housing 2 having a shape in which the first housing portion 21 and the second housing portion 22 having different outer diameters are combined. The light emitting device 3 is housed inside the housing portion 22 and is installed on the upper part of the line-of-sight guide pillar 4.

In this embodiment, the side of FIGS. 1 and 2 in which the second housing portion 22 is arranged is defined as the upper side when viewed from the side in which the first housing portion 21 is arranged. explain. For example, in the case of FIG. 1, a light emitting device 3 is housed inside the light emitting body 1 for the line-of-sight guidance pillar, and the upper end portion of the line-of-sight guidance pillar 4 is inserted under the light emitting body 1 for the line-of-sight guidance pillar. ing.

FIG. 2 is a perspective view showing an example of the configuration of the light emitting body 1 for the line-of-sight guide pillar. Further, FIG. 3 is an exploded view showing an example of the configuration of the light emitting body 1 for the line-of-sight guidance pillar. With reference to FIGS. 2 and 3, the line-of-sight guidance pillar light emitter 1 has a housing 2 having a shape in which a first housing portion 21 and a second housing portion 22 having different outer diameters are combined, and a middle plate 31. It is composed of a light emitting device 3 including a substrate 32 and an upper plate 33.

As shown in FIG. 2, the light emitting device 3 can be housed inside the second housing portion 22 located on the upper end side of the housing 2. Further, as shown in FIG. 3, the light emitting device 3 housed inside the second housing portion 22 (light emitting body 1 for the line-of-sight guide pillar) can be removed from the lower end side of the housing 2. As will be described later, the housing 2 has an insertion hole through which the line-of-sight guide pillar 4 is inserted, and the light emitting device 3 is housed in the upper end side of the insertion hole formed in the housing 2.

Referring to FIGS. 3 and 4, the housing 2 has a substantially cylindrical shape in which the upper end side is curved above the substantially cylindrical first housing portion 21, and is larger than the first housing portion 21 in a plan view. It has a shape in which a second housing portion 22 having a small outer diameter is connected. Further, as shown in the cross-sectional view taken along the line AA of FIG. 5, an insertion hole is formed in the housing 2 from the lower end side of the housing 2 upward. Specifically, the first insertion hole 211 is formed in the portion of the housing 2 corresponding to the first housing portion 21, and the second insertion hole 221 is formed in the portion corresponding to the second housing portion 22. Is formed. Further, the first insertion hole 211 formed in the first housing portion 21 and the second insertion hole 221 formed in the second housing portion 22 are smoothly connected to each other. By forming the housing 2 in this way, the light emitting device 3 can be housed inside the second insertion hole 221 from the lower end side of the housing 2 via the first insertion hole 211. The first insertion hole 211 and the second insertion hole 221 have, for example, an inner diameter corresponding to the outer diameter of the housing in which each insertion hole is formed. For example, in the present embodiment, the second insertion hole 221 has an inner diameter smaller than that of the first insertion hole 211 in a plan view.

With reference to FIGS. 4 and 5, the side surface of the second insertion hole 221 (that is, the upper side of the housing 2) formed in the second housing portion 22 is covered with a casing from the inner surface of the second insertion hole 221. A plurality of (singular, for example, four) lower locking pieces 222 (locking pieces) and upper locking pieces 223 (locking pieces) projecting horizontally toward the inside of the body 2 are formed. Has been done. That is, for example, four lower locking pieces 222 are formed on the lower side of the inner surface of the second insertion hole 221 and, for example, four upper locking pieces 223 are formed on the upper side of the inner surface of the second insertion hole 221. Has been done. As will be described later, among the constituent elements constituting the light emitting device 3, the middle plate 31 is locked by the lower locking piece 222, and the upper plate 33 is locked by the upper locking piece 223. As a result, the light emitting device 3 is locked inside the second insertion hole 221.

Further, as shown in FIGS. 2 to 6, the inner surface of the second insertion hole 221 formed in the second housing portion 22 has an arcuate convex portion 224 (an arc-shaped convex portion 224 protruding toward the inside of the housing 2). A plurality of convex portions for light diffusion) are formed. By forming a plurality of convex portions 224 on the inner surface of the second insertion hole 221, the light emitted by the light emitting device 3 can be diffused. As a result, the light emitted by the light emitting device 3 can be diffused over a wider range.

In the present embodiment, as shown in FIGS. 4 and 7, of the above-mentioned upper locking piece 223 and lower locking piece 222, the upper locking piece 223 is formed on the convex portion 224. The lower locking piece 222 is formed below the portion where the convex portion 224 is formed. The upper locking piece 223 and the lower locking piece 222 may be formed in places other than those illustrated in the present embodiment.

Further, referring to FIGS. 3 to 5, the rivet penetration penetrating the first housing portion 21 from the outside to the inside of the housing 2 (that is, toward the thickness direction of the first housing portion 21). For example, four holes 212 are formed. By inserting the upper end portion of the line-of-sight guide pillar 4 into the first housing portion 21 located below the housing 2 and then inserting the rivet into the rivet through hole 212, the housing 2 (that is, the light emitting body for the line-of-sight guide pillar) is inserted. 1) will be fixed to the line-of-sight guide pillar 4.

As the rivet to be inserted into the rivet through hole 212, it is desirable to use a resin-made rivet (for example, weather-resistant AES (acrylonitrile / ethylene-propylene-diene / styrene) resin). If a metal member such as a screw is used when attaching the line-of-sight guide pillar 1 to the line-of-sight guide pillar 4, the metal member may cause secondary damage such as injury or puncture when damaged due to a traffic accident or the like. .. By using a resin rivet when attaching the line-of-sight guide pillar 1 to the line-of-sight guide pillar 4, it is possible to reduce the above risk.

Further, the rivet in the present embodiment has a recessed portion formed near the center of the head, and is configured so that the rivet can be easily broken by pushing a predetermined tool into the recessed portion. By configuring the rivet in this way, it is possible to easily remove the light emitting body 1 for the line-of-sight guide pillar 4 from the line-of-sight guide pillar 4 after the light-emitting body 1 for the line-of-sight guide pillar is installed on the line-of-sight guide pillar 4 by the rivet. Will be.

The light emitting device 3 includes a middle plate 31 arranged on the lower end side when the light emitting device 3 is locked inside the second insertion hole 221 and an upper plate 33 arranged on the upper end side, and the middle plate 31 and the upper side. It includes a substrate 32 arranged between the plates 33 (see FIG. 3).

As shown in FIG. 3, the middle plate 31 has, for example, a substantially circular shape in a plan view. Further, on the side surface of the middle plate 31, for example, four middle plate notches 311 which are recesses are formed. The middle plate notch portion 311 is formed at a position corresponding to the formation position of the lower locking piece 222 formed in the second housing portion 22. By inserting the middle plate 31 into the upper part in a state where the middle plate notch 311 is aligned with the forming portion of the lower locking piece 222, the middle plate 31 is seconded without being locked to the lower locking piece 222. It can be inserted into the upper part of the insertion hole 221. Further, by rotating the middle plate 31 in the horizontal direction in that state, the lower locking piece 222 can be brought into contact with the lower part of the middle plate 31 where the middle plate notch 311 is not formed. The side locking piece 222 makes it possible to lock the middle plate 31.

Further, as shown in FIG. 3, a finger insertion hole 312 penetrating in the vertical direction (thickness direction of the middle plate 31) is formed at a predetermined position of the middle plate 31. The finger insertion hole 312 can be used when rotating the above-mentioned middle plate 31. By rotating the middle plate 31 with the finger inserted in the finger insertion hole 312, the middle plate 31 can be easily rotated. A finger is inserted into the finger insertion hole 312, and the middle plate 31 is rotated with the finger inserted. Therefore, it is desirable that the finger insertion hole 312 has a shape (for example, an elliptical shape) in which a finger can be easily inserted rather than a perfect circular shape.

Further, for example, four middle plate columns 313 extending upward are formed on the upper surface of the middle plate 31. The middle plate 31 is connected to the upper plate 33 by connecting the middle plate pillar 313 and the upper plate pillar 333 formed on the upper plate 33, which will be described later, with the substrate 32 sandwiched between them. The middle plate pillar 313 and the upper plate pillar 333 are connected by, for example, inserting a convex portion formed at one side end portion into a concave portion formed at the other side end portion. Due to such a structure, the connection state between the middle plate pillar 313 and the upper plate pillar 333 can be easily released, and the substrate 32 sandwiched between the middle plate pillar 313 and the upper plate pillar 333 can be separated. It can also be easily removed.

The substrate 32 has, for example, a substantially quadrangular shape in a plan view. Through holes are formed at the four corners of the substrate 32 so as to penetrate in the thickness direction of the substrate 32. By inserting a convex portion formed on one of the middle plate pillar 313 or the upper plate pillar 333 into the through hole formed in the substrate 32, the substrate 32 is sandwiched between the middle plate pillar 313 and the upper plate pillar 333. It is possible to connect in a state of being.

As shown in FIGS. 5 and 7, a light emitting diode 321 is provided at a predetermined position on the lower side of the substrate 32. For example, light emitting diodes 321 are provided near the center of each side of the quadrangle forming the substrate 32. That is, the light emitting diodes 321 are provided in four directions of the substrate 32. Further, as shown in FIGS. 4 and 5, for example, a cylindrical storage battery 322 is arranged on the upper part of the substrate 32.

The storage battery 322 is connected to a solar cell 332 arranged above the upper plate 33, which will be described later, and stores electricity generated by the solar cell 332. Further, the storage battery 322 is connected to the light emitting diode 321. The light emitting diode 321 emits light having a predetermined wavelength by receiving electricity from the storage battery 322 (the wavelength of the light emitted by the light emitting diode 321 is not particularly limited). The light emitting diode 321 may be configured to emit light having a predetermined wavelength by receiving electricity directly from the solar cell 332.

An optical sensor (not shown) can be arranged on the substrate 32 (or the upper plate 33). By providing the optical sensor, for example, it is possible to configure the light emitting diode 321 to light only when the surroundings become dark. The light emitting diode 321 may have a function as an optical sensor.

As shown in FIG. 3, the upper plate 33 has, for example, a substantially circular shape in a plan view. Further, on the side surface of the upper plate 33, for example, four upper plate notch portions 331 are formed. The upper plate notch portion 331 is formed at a position corresponding to the formation position of the upper locking piece 223 formed in the second housing portion 22. By inserting the upper plate 33 into the upper part in a state where the upper plate notch 331 is aligned with the forming portion of the upper locking piece 223, the upper plate 33 is inserted into the second insertion hole without being locked by the upper locking piece 223. It can be inserted into the upper part of 221. Further, by rotating the upper plate 33 in that state, the upper locking piece 223 can be brought into contact with the lower part of the upper plate 33 where the upper plate notch 331 is not formed, and the upper locking piece 223 can be brought into contact with the upper plate 33. This makes it possible to lock the upper plate 33. As described above, the upper plate 33 is connected to the lower plate 31 via the upper plate pillar 333, which will be described later. Therefore, by rotating the lower plate 31, the upper plate 33 also rotates with the rotation of the lower plate 31.

As shown in FIG. 3, for example, a solar cell 332 having a substantially rectangular shape in a plan view is arranged on the upper surface of the upper plate 33. As described above, the solar cell 332 can be connected to the light emitting diode 321 and the storage battery 322.

Further, on the lower surface of the upper plate 33, for example, four upper plate columns 333 extending downward are formed. As described above, the upper plate 33 can be connected to the middle plate 31 by connecting the upper plate pillar 333 and the middle plate pillar 313 with the substrate 32 sandwiched between them.

As shown in FIG. 4, in the present embodiment, the upper plate 33 has a circular shape having a diameter slightly smaller than that of the middle plate 31 in a plan view. This is because the convex portion 224 is formed on the second housing portion 22.

The above is an example of the configuration of the light emitting body 1 for the line-of-sight guide pillar.

なお、表１のうち、引張降状応力は、材料が破損しない目安を示している。曲げ弾性率は、変形のしにくさの値を示している。曲げ強度は、破壊に至るまでの最大荷重を基に算出した曲げ応力の値を示している。ノッチ付きシャルピー衝撃強さは、対象の両端を支え、ノッチ部の背面をハンマーで打撃させたときの破壊する値を示している。ロックウェル硬度は、押し込みの硬さを示している。荷重たわみ温度は、温度を上げてたわみの大きさが一定になる値を示している。線膨張係数は、温度上昇により物体の長さが膨張するときの割合を示している。 Here, Table 1 shows an example of a physical property comparison table comparing specific material types and physical properties of the housing 2, the rivet, and the line-of-sight guide pillar 4. However, Table 1 shows only an example of the types and physical characteristics of the housing 2, the rivet, and the line-of-sight guide pillar 4. Needless to say, the types and physical properties of the housing 2, the rivet, and the line-of-sight guide pillar 4 are not limited to those shown in Table 1 below.

In Table 1, the tensile descending stress shows a guideline for not damaging the material. The flexural modulus indicates the value of the difficulty of deformation. Bending strength indicates the value of bending stress calculated based on the maximum load leading to fracture. The notched Charpy impact strength indicates the value at which both ends of the object are supported and the back surface of the notch is destroyed when hit with a hammer. Rockwell hardness indicates the hardness of indentation. The deflection temperature under load indicates a value at which the magnitude of deflection becomes constant as the temperature is raised. The coefficient of linear expansion indicates the rate at which the length of an object expands due to an increase in temperature.

Referring to Table 1, the housing 2 is less likely to bend than the line-of-sight guide pillar 4, and is less likely to be broken by tension, bending, or impact. That is, the housing 2 is stronger than the line-of-sight guide pillar 4. Further, the rivet is more fragile than the housing 2 due to tension, bending, and impact. Therefore, when an impact is generated due to an accident or the like, the rivet is broken before the housing 2. As a result, the housing 2 is separated from the line-of-sight guide pillar 4, and the possibility that the housing 2 is broken can be reduced.

Further, as shown in Table 1, the tendency is that the strength of the rivet is stronger than the strength of the line-of-sight guide pillar 4. On the other hand, regarding the notched Charpy impact strength, the line-of-sight guide pillar 4 has a higher value than the rivet. This is because urethane is soft and therefore elastic and has the property of absorbing the impact of a hammer or the like, while rivets are vulnerable to impact due to their high hardness. Further, the housing 2 has a higher value than the rivet and the line-of-sight guide pillar 4 with respect to the notched Charpy impact strength. That is, the housing 2 is stronger against impact than the line-of-sight guide pillar 4, while the rivet is weaker than the line-of-sight guide pillar 4. By configuring the housing 2, the rivet, and the line-of-sight guide pillar 4 in this way, for example, when an impact occurs due to an accident or the like, the rivet breaks before the housing 2, the line-of-sight guide pillar 4, breaks. become. As a result, it is possible to reduce the possibility that the housing 2 is broken, and it is possible to suppress the occurrence of secondary damage due to the broken housing 2.

Further, referring to Table 1, the housing 2 and the rivet have higher heat resistance than the line-of-sight guide pillar 4, and are less likely to expand due to heat. That is, the housing 2 and the rivet in the present embodiment are more resistant to heat than the general line-of-sight guide pillar 4.

As described above, the line-of-sight guidance pillar light emitting body 1 has a housing 2 and a light emitting device 3. Further, an insertion hole is formed in the housing 2, and a lower locking piece 222 and an upper locking piece 223 are formed. With such a configuration, the light emitting device 3 is housed inside the second housing portion 22 which is the upper end side of the housing 2, and the light emitting device is formed by the lower locking piece 222 and the upper locking piece 223. 3 can be easily locked. Then, with the light emitting device 3 locked inside the second housing portion 22, the upper end portion of the line-of-sight guidance pillar 4 is inserted into the inside of the first housing portion 21 which is the lower end side of the housing 2. .. After that, the housing 2 (that is, the light emitting body 1 for the line-of-sight guide pillar) is installed in the line-of-sight guide pillar 4 by inserting a resin rivet through the rivet through hole 212. Thereby, the light emitting body 1 for the line-of-sight guide pillar can be installed on the line-of-sight guide pillar 4 by an easy method.

Conventionally, in a state where the upper end of the line-of-sight guide pillar 4 is cut and the line-of-sight guide pillar 4 is inserted into the line-of-sight guide pillar 4, the light-emitting body 1 for the line-of-sight guide pillar 1 is used with a metal screw or the like. Was generally fixed to the line-of-sight guide pillar 4. According to the light emitting body 1 for the line-of-sight guide pillar described in the present embodiment, the light-emitting body 1 for the line-of-sight guide pillar 4 can be attached to the line-of-sight guide pillar 4 only by providing a through hole for inserting a rivet in the line-of-sight guide pillar 4. Therefore, the work required at the site for installation is reduced, and easy installation is possible.

Further, according to the present embodiment, after releasing the installation state with respect to the line-of-sight guide pillar 4 (for example, by breaking the rivet), for example, by inserting a finger into the finger insertion hole 312 and rotating the middle plate 31 (described above). As described above, the upper plate 33 also rotates), the locked state by the lower locking piece 222 and the upper locking piece 223 is released, and the light emitting device 3 can be easily removed from the housing 2. As a result, for example, the substrate 32 and the solar cell 332 can be easily removed, and even if any failure occurs in any of the members constituting the light emitting device 3 such as the substrate 32 and the solar cell 332. It is possible to replace only the part where the failure has occurred by various methods.

The light emitting body 1 for the line-of-sight guide pillar in the present embodiment does not have a square portion in its outer shape, and each corner portion is curved. Since the light emitting body 1 for the line-of-sight guide pillar is installed outside, for example, a child or the like may touch it. By adopting the housing 2 that does not have an angular portion like the light emitting body 1 for the line-of-sight guidance pillar in the present embodiment, it is possible to reduce the risk of injury when a child or the like touches it.

Further, in the present embodiment, the housing 2 has a shape in which the first housing portion 21 and the second housing portion 22 having different outer diameters are combined. However, the housing 2 does not necessarily have to have a shape in which the first housing portion 21 and the second housing portion 22 having different outer diameters are combined. The housing 2 may have, for example, a cylindrical shape having an insertion hole from the lower end side toward the upper side. That is, the outer diameters of the first housing portion 21 and the second housing portion 22 may be the same. Further, in the present embodiment, the entire light emitting device 3 is housed inside the second insertion hole 221 of the second housing portion 22, but for example, a part of the light emitting device 3 such as the middle plate 31 is housed in the first housing. It may be configured to be locked while remaining inside the first insertion hole 211 of the body portion 21.

Further, it is also conceivable to apply a reflection treatment for reflecting light such as silver plating or silver coating on the surface of the middle plate 31 and the upper plate 33 on the substrate 32 side. The reflection treatment may be applied to only one of the above, for example, only the surface of the middle plate 31. With this configuration, the light emitted from the light emitting diode 321 can be emitted to the outside more efficiently.

Further, in the present embodiment, it is assumed that the light emitting body 1 for the line-of-sight guide pillar is installed above the line-of-sight guide pillar 4. However, the target on which the light emitting body 1 for the line-of-sight guide pillar 1 is installed is not limited to the line-of-sight guide pillar 4. The light emitting body 1 for the line-of-sight guide pillar may be installed on various pillars other than the line-of-sight guide pillar 4.

Further, in the present embodiment, it is assumed that the lower locking piece 222 and the upper locking piece 223 are formed on the second housing portion 22. However, as long as either one of the lower locking piece 222 and the upper locking piece 223 is formed on the second housing portion 22, both may not necessarily be formed.
