JP 2003-208808 A

  Various stair lighting devices are known in addition to the device described in Patent Document 1 above, all of which illuminate the entire staircase or darken the tread on each step. It was intended to illuminate a specific part.

  However, when actually going up and down the stairs, the place where pedestrians should pay the most attention because there is a risk of stepping off or crawling is the stairs entrance. In other words, when going down the stairs, it is most important for pedestrians to step down from the upper floor to the staircase with a step and carry a few steps along the steps. Pedestrians can feel the slope and spacing of the steps by carrying a few steps along the steps, and there is less danger because they can walk at the same pace on subsequent descents.

  On the other hand, at the lower end of the stairs, on the contrary, it is necessary to stop the steps that have been taken down along the stairs, and in order to perform this smoothly, pedestrians on the way down the stairs are clearly visible. It is necessary to recognize the lower end (end) of the stairs.

  Similarly, when a pedestrian goes up the stairs from the lower floor, the pedestrian needs the most attention until he goes up the steps from the lower floor to the staircase with a step and carries a few steps along the step. By the way. Pedestrians can feel the slope and spacing of the steps by carrying two or three steps along the steps, and the subsequent climbs only need to proceed at the same pace, so there is little danger.

  On the other hand, at the upper end of the stairs, on the contrary, the feet that have been raised along the stairs must be stopped. In order to do this smoothly, pedestrians on the stairs are clearly visible It is necessary to recognize the top (end) of the stairs.

  From the above viewpoint, with the conventional lighting device that illuminates the entire staircase, the pedestrian's attention is dispersed, and the risk of the pedestrian stepping out and crawling at the stair lift is sufficiently reduced. It is difficult to do.

  In addition, in the lighting device described in Patent Document 1, the steps before and after the step that the pedestrian steps on are not illuminated, but follow the movement of the pedestrian. When going down the stairs from the floor, the lower end of the stairs is not illuminated, so the pedestrian cannot clearly recognize the lower end of the stairs visually in the middle of the stairs, and the distance from the current position to the lower end of the stairs It is difficult to grasp clearly, and there is a risk that pedestrians may crawl or fall over at the exit of stairs, and it cannot be said that safety is sufficiently achieved.

  Therefore, according to the present invention, the stair lift that the pedestrian should pay the most attention to is recognized distinctly from the steps in the middle of the staircase, etc., and it is possible to prevent the pedestrian from stepping or stroking. An object of the present invention is to provide a highly safe stair lighting device.

In order to achieve the above object, the invention according to claim 1 includes an upper tread that continues to the floor of the upper floor, a lower tread that continues to the floor of the lower floor, and a step tread that is disposed between the upper tread and the lower tread. A plurality of stepped surfaces close to the upper stepped surface, embedded in the stepped surface and illuminating the stepped surface, and an upper guide light that illuminates the stepped surface, A plurality of stepped surfaces close to the lower stepped surface are provided with a lower guide light that is buried in the stepped surface and illuminates the stepped surface, and the upper stepped surface and / or the lower stepped surface, A boundary indicator light extending in a direction perpendicular to the ascending / descending direction of the stairs and further showing a boundary between the stairs and the floor is further provided, and the boundary indicator light is allowed to go down to the step surface and / or the upper tread surface and / or The top is on the step surface It is characterized only provided Rukoto on the lower tread allowed go.

According to the first aspect of the present invention, the stairs to which pedestrians should pay most attention are clearly distinguished from the steps in the middle of the stairs, etc., to prevent the pedestrian from stepping off or stroking. In addition to improving safety, the stairs can be clearly recognized from pedestrians passing through the upper and lower floors, and safety at the stairs can be further enhanced. it can. Moreover, the advancing direction of a pedestrian can be ordered and the safety | security in the lift of a staircase can be improved more.

  Hereinafter, a lighting device according to a first embodiment of the present invention will be described with reference to FIG. First, the structure of the staircase provided with the lighting device will be described. The staircase 1 is disposed between the upper tread 21 and the lower tread 22, and the upper tread 21 having a relatively large area that is continuous with the upper floor, the lower tread 22 having a relatively large area that is continuous with the lower floor. 8-step step surfaces 31, 32, 33, 34, 35, 36, 37, 38, side walls 41, 42 orthogonal to the step surfaces on both sides of the step surfaces 31-38, and inclinations of the step surfaces 31-38 Are provided with handrails 51 and 52 attached to both side walls 41 and 42.

  In the first embodiment, the upper guide lights 61, embedded in the respective step surfaces, near the right ends of the first, second and third step surfaces 31, 32, 33 close to the upper step surface 21, 62, 63 are provided, and the lower guide lights 71, 72 are embedded in the respective step surfaces near the right ends of the sixth, seventh and eighth step surfaces 36, 37, 38 close to the lower step surface 22. 73 is provided.

  The upper guide lights 61, 62, 63 and the lower guide lights 71, 72, 73 have the same structure, and the structure of the upper guide light 61 is shown in FIG. 8 as a representative. The upper guide light 61 includes a box casing 101 embedded in the step surface 31, two tempered glasses 102 and 103 fixed to the top of the box casing 101, and a support base 104 inside the box casing 101. The LED unit 105 is fixed via a lead wire, and a lead wire retainer 107 for fixing the lead wire 106 from the LED unit 105 is provided. When power is supplied to the LED unit 105 from a power source (not shown) via the lead wire 106, the LED 108 emits light and is illuminated through the tempered glass 102 and 103.

  In addition, when the place where the staircase is installed is outdoors, the guide lights 61, 62, 63, 71, 72, 73 may be supplied with power by solar cells. FIG. 9 shows the structure of a guide light 161 with a solar cell. The same structural parts as those of the guide light 61 shown in FIG. A guide light 161 with a solar cell includes two solar cell panels 111 and 112 at the lower ends of the tempered glasses 102 and 103, and electricity generated in the solar cell panel is below one solar cell panel 111. Is stored in a storage battery 113 provided in the battery. When this guide light 161 with a solar cell is used, it is not necessary to supply electricity, and it is not necessary to attach power supply equipment such as a power cable, so that the equipment cost can be reduced.

  Next, the case where a pedestrian goes up and down the stairs 1 provided with the illuminating device of 1st Embodiment is demonstrated. Assuming that the pedestrian goes down the stairs from the upper floor to the lower floor, the pedestrian is in the first to third steps close to the upper tread 21 by the upper guide lights 61, 62, 63 emitting light. The stepped surfaces 31, 32, and 33 can be clearly seen, and the feet can be safely and reliably lowered on the stepped surfaces 31, 32, and 33.

  A pedestrian who has stepped up to the third step surface 33 can feel the gradient of the stairs 1 and the distance between the step surfaces 31 to 33 (required step length), and the fourth and fifth step surfaces 34 and 35. Can be safely lowered even if the fourth and fifth step surfaces 34 and 35 are not brightly illuminated.

  And the pedestrian can clearly recognize the step surfaces 36, 37, 38 from the sixth to the eighth step close to the lower step surface 22 by the lower guide lights 71, 72, 73 emitting light, The end of the stairs 1 can be reliably recognized, and the foot can be lowered safely and reliably from the last step surface (eighth step surface) 38 to the lower step surface 22.

  In addition, the illuminating device of this embodiment is an example in which the upper guide lights 61, 62, 63 and the lower guide lights 71, 72, 73 are provided over the three stepped surfaces 31-33, 36-38. However, both the upper guide light and the lower guide light may be provided over the two stepped treads 31, 32, 37, and 38, or the four stepped treads 31 adjacent to the upper tread 21 and the lower tread 22. -34, 35-38 may be provided. Further, in the case of a long staircase having more step surfaces, a configuration in which five or more step surfaces are illuminated by the upper guide light and the lower guide light may be employed.

  In the case of the stairs 1 having the eight step surfaces 31 to 38 as in the present embodiment, if each of the upper guide light and the lower guide light illuminates the two step surfaces 31, 32, 37, 38, The third to sixth step surfaces 33, 34, 35, and 36 are step surfaces that are not illuminated by the guide light. In addition, if each of the upper guide light and the lower guide light is configured to illuminate the four stepped surfaces 31, 32, 33, 34, 35, 36, 37, 38, all the stepped surfaces are illuminated by the guide lights. It will be.

  The number of step surfaces illuminated by the upper guide light and the lower guide light is appropriate to be 3 steps. When the number of stepped surfaces on which the guide light is provided is 2, the equipment cost is reduced, but the number of steps that can be clearly seen by pedestrians at the exit or exit of the stairs is reduced, so that pedestrians can safely walk. The number of steps that can be carried is reduced, and the safety is reduced accordingly. Further, when the step surface on which the guide light is provided is 4, the number of steps on which the pedestrian can surely go is increased, and the safety is improved correspondingly, but the equipment cost is increased. On the other hand, if the pedestrian advances about 3 steps along the stepped surfaces 31 to 38 with steps, the pedestrian can feel the gradient of the stairs, the interval between the stepped surfaces (required step length), and the like.

  Next, an illumination device according to a second embodiment will be described with reference to FIG. The structure of the staircase 1 provided with the illumination device of the second embodiment is the same as the staircase in the first embodiment. In the second embodiment, the reflective surfaces 261a, 262a, and 263a are fixed to the step surfaces near the right ends of the first, second, and third step surfaces 31, 32, and 33 that are close to the upper step surface 21, respectively. The upper guide lights 261, 262, and 263 are provided at the position of the handrail 52 facing the reflecting surfaces 261a to 263a. Further, reflecting surfaces 271a, 272a, and 273a are provided near the right ends of the sixth, seventh, and eighth step surfaces 36, 37, and 38 adjacent to the lower tread surface 22, and are provided on the step surfaces. Lower guide lights 271, 272, and 273 are provided at positions of the handrail 52 facing the 271 a to 273 a. The reflective surfaces 261a to 263a and 271a to 273a can be made of tempered glass or metal plate having a high light reflectivity, and directly apply a highly reflective paint to the step surfaces 31 to 33 and 36 to 38. It can also be configured.

  When the upper guide lights 261 to 263 are turned on, the reflecting surfaces 261a to 263a of the first, second and third stepping surfaces 31 to 33 are illuminated, and the first, second and third pedestrians are illuminated by the pedestrian. The positions of the step surfaces 31 to 33 are clearly visible. Similarly, when the lower guide lights 271 to 273 are turned on, the reflecting surfaces 271a to 273a of the sixth, seventh and eighth step surfaces 36 to 38 are illuminated, and the sixth, seventh and eighth steps are illuminated by the pedestrian. The positions of the stepped surfaces 36 to 38 are clearly visible.

  Similarly to the first embodiment, the staircase 1 including the lighting device of the second embodiment is lit mainly in the vicinity of the lower end and the upper end of the staircase that requires the most attention. The stairs can be raised and lowered safely without making a mistake such as stepping off the tread 21 or hitting the lowermost step tread 38.

  In addition, when the light reflectivity of the step surfaces 31 to 38 itself is high, it is not necessary to provide a reflection surface on the step surfaces 31 to 38. Also, the mounting positions of the upper guide lights 261 to 263 and the lower guide lights 271 to 273 are not the handrail 52, but the positions on the side walls 42 facing the first, second, and third step surfaces 31 to 33, and The position on the side wall 42 facing the sixth, seventh, and eighth step surfaces 36 to 38 may be used. In this case, the upper guide lights 261 to 263 and the lower guide lights 271 to 273 can be provided close to the reflecting surfaces 261a to 263a and 271a to 273a, so that the step surfaces 31 to 33 and 36 to 38 are brighter. Can be illuminated.

  Next, a lighting device according to a third embodiment will be described with reference to FIG. The structure of the staircase 1 in which the illumination device of the third embodiment is provided is the same as the staircase in the first embodiment. The lighting device of the third embodiment has the same structure as that of the lighting device of the first embodiment (the description is omitted by assigning the same number to the same structural portion), and the upper tread 21 and the lower tread 22. In addition, boundary display lights 301 and 302 indicating the boundary between the staircase 1 and the upper and lower floors are provided.

  The boundary display lights 301 and 302 have the same structure as the upper guide light 61 shown in FIG. 8, and are formed in a rectangular shape extending long in a direction orthogonal to the ascending / descending direction of the stairs as shown in FIG. Yes.

  In the case of the third embodiment, as in the first embodiment, the upper guide lights 61 to 63 provided on the step surfaces 31 to 33 and the lower guide lights 71 provided on the step surfaces 36 to 38. The pedestrian can safely move up and down the stairs 1 through 73, and the boundary display lights 301 and 302 having shapes that are clearly different from the guide lights 61 through 63 and 71 through 73 can respectively be used to connect the upper tread 21 to the step 31. Since the exit from the exit and the lower tread 22 to the step surface 38 is displayed, a pedestrian walking on the upper floor and the lower floor can clearly see the elevator of the stairs 1 and walking on the upper floor The risk of a pedestrian walking off the stairs (step surface 31) or a pedestrian walking on the lower floor crawling on the lowermost step surface 38 is reduced.

  Further, since the boundary display lights 301 and 302 and the respective guide lights 61 to 63 and 71 to 73 are disposed near the right end in FIG. 3 and are disposed close to one handrail 52, the pedestrian displays the boundary display lights 301. , 302 and each of the guide lights 61 to 63 and 71 to 73, the pedestrian is guided to the handrail 52, and the pedestrian moves up and down the stairs 1 while handrailing the handrail, so that safety is further improved.

  Next, an illumination device according to a fourth embodiment will be described with reference to FIG. The structure of the staircase 1 in which the illumination device of the fourth embodiment is provided is the same as that of the staircase 1 in the first embodiment, but is a staircase in which the traveling direction of the pedestrian is restricted to left-hand traffic. The traveling direction of the pedestrian is indicated by an arrow in FIG. The illumination device of the fourth embodiment includes upper guide lights 401 to 403 and 411 to 413 embedded on both sides of the first, second and third step surfaces 31, 32 and 33 close to the upper step surface 21. Lower guide lights 404 to 406 and 414 to 416 embedded on both sides of the sixth, seventh and eighth step surfaces 36, 37 and 38 adjacent to the lower tread surface 22, and embedded near the right end of the upper tread surface 21. A boundary display light 421 and a boundary display light 422 embedded near the left end of the lower tread 22 are configured.

  Since the entrance to stairs 1 is illuminated by boundary indicator lights 421 and 422, a pedestrian who goes down stairs 1 from the upper floor is guided to the left side toward stairs 1, and a pedestrian who goes up stairs 1 from the lower floor , You will be directed to the left side towards stairs 1. Accordingly, the risk that a pedestrian walking on the upper floor and the lower floor will step out of the upper tread 21 at the entrance of the staircase 1 or go to the lowermost step surface 38 is reduced, and the stairs 1 The pedestrian's flow is correctly restricted to the left-hand traffic. By restricting pedestrians to left-hand traffic, collision, approach, crossing, and the like between pedestrians are less likely to occur, and safety is further enhanced. In the case of a stairs restricted to right-hand traffic, a boundary display light 421 is provided near the left end of the upper tread surface 21 and a boundary display light 422 is provided near the right end of the lower tread surface 22 in FIG.

  Next, a lighting device according to a fifth embodiment will be described with reference to FIG. The structure of the staircase 1 provided with the lighting device of the fifth embodiment is the same as the staircase 1 in the first embodiment, and the traveling direction of the pedestrian is restricted to the left-hand traffic as in the fourth embodiment. It is a stairs. The traveling direction of the pedestrian is indicated by an arrow in FIG.

  Further, the lighting device of the fifth embodiment is embedded in the left end of the upper tread 21 in addition to the same structure as that of the lighting device of the fourth embodiment (description is omitted by attaching the same number to the same structure portion). The boundary display light 501 and the boundary display light 502 embedded in the right end of the lower tread 22 are provided. Then, the boundary display light 501 on the left side of the upper tread 21 corresponding to the position where the pedestrian is away from the stairs 1 and the boundary display light 502 on the right side of the lower tread 22 emit red light to alert the pedestrian. The remaining boundary display lights 421 and 422 and guide lights 401 to 403, 411 to 413, 404 to 406, and 414 to 416 are configured to emit white light.

  Accordingly, the pedestrian is guided by the white boundary display lights 421 and 422 and the white guide lights 411 to 413 and 406 to 404 that follow the white boundary display lights 421 and 422, and then goes down the stairs 1 (arrow A) or up ( Arrow B), the red boundary indicator lights 502 and 501 can clearly recognize the end of the staircase 1 and safely leave the step surfaces 38 and 31 of the staircase and proceed to the lower or upper floor (arrow C). , Arrow D). Further, similarly to the fourth embodiment, the flow of pedestrians is correctly restricted to left-hand traffic, and collisions, approaching, crossing, and the like between pedestrians are less likely to occur, further improving safety. The emission colors of the boundary display lights 501 and 502 corresponding to the separation position from the staircase 1 are not limited to red, and may be other colors. Other boundary display lights 421 and 422 and guide lights 401 to 406 and 411 to 416 Any color can be used as long as the distinction is clear.

  Next, an illumination device according to a sixth embodiment will be described with reference to FIG. The structure of the staircase 1 in which the illumination device of the sixth embodiment is provided is the same as that of the staircase 1 in the first embodiment. The lighting device of the sixth embodiment includes upper guide lights 601, 602 embedded in the side wall 42 in the vicinity of the first, second and third step surfaces 31, 32, 33 close to the upper step surface 21. 603, lower guide lights 604, 605, 606 embedded in the side wall 42 in the vicinity of the sixth, seventh and eighth step surfaces 36, 37, 38 adjacent to the lower tread surface 22, and in the vicinity of the upper tread surface 21 A boundary display light 611 embedded in the side wall 42 and a boundary display light 612 embedded in the side wall 42 in the vicinity of the lower tread 22 are configured. The upper guide lights 601 to 603, the lower guide lights 604 to 606, and the boundary display lights 611 and 612 have the same structure as the upper guide light 61 shown in FIG.

  In the stairs 1 of the sixth embodiment, the pedestrian can safely ascend and descend the stairs 1 in the same manner as the stairs 1 of the third embodiment described above, and each guide light 601 to 606 and the boundary display light 611 , 612 are provided on the side wall 42 instead of the treads 21 and 22 and the step treads 31 to 38, and the following advantages are obtained.

  That is, the step surfaces 31 to 38 of the staircase 1 may be variously restricted in terms of anti-overload and safety against slipping, particularly in the staircase 1 installed outdoors. Even in that case, in the sixth embodiment, each of the guide lights 601 to 606 and the boundary display lights 611 and 612 are provided on the side wall 42, so that they can be installed relatively freely regardless of the regulations regarding the stepped surfaces. . Further, the step surfaces 31 to 38 can be freely manufactured within the range of the regulation. In other words, for example, when a guide light is provided on the stepped surfaces 31 to 38 under the above-described regulations, there is a problem that the strength of the tempered glass on the surface of the guide light must be considerably increased. However, when the guide lights 601 to 606 and the boundary display lights 611 and 612 are provided on the side wall 42, such a problem can be avoided.

  As shown in FIG. 7, only the boundary display lights 611 and 612 for clearly showing the elevator of the staircase 1 are not provided on the side wall 42, but are provided on the upper tread 21 and the lower tread 22, respectively. Also good. In this case, since the stairs are more clearly recognized by the pedestrian than in the stairs 1 shown in FIG. 6, safety is further enhanced.
