[Prior art]

 An example of an accident that occurs in a building is an accident on stairs. Especially at night, it is difficult to recognize not only the position of the steps of the stairs, but also the width and depth of the steps, which may lead to a serious accident by falling off the foot.

Therefore, a spotlight may be provided by using the side wall of the stairs or a handrail, but depending on the position and ability of the light, a shadow or the like may be difficult to see on the tread, or the foot may be illuminated well. There is a problem that you can not.

As means for displaying the position of the stair tread portion at night, for example, those disclosed in Japanese Utility Model Publication No. 5-14976 and Japanese Utility Model Publication No. 5-14978 are known. In the former case, in order to illuminate the front edge upper edge portion including the side edge corners of the tread, the front edge upper edge portion is formed of a translucent synthetic resin material and the light source is arranged on the back portion. The position of is displayed. According to this structure, the light source may have a low luminous intensity because of the position display, and the power consumption may be small.

On the other hand, the latter is composed of means for providing a recess on the lower surface of the front end of the tread, forming a small hole communicating from the recess to the surface (upper surface) of the tread, and accommodating a lighting fixture in the recess. It illuminates the bottom tread and allows the position to be confirmed by the light leaking from the small hole to the top of the tread.

However, there is a problem that any of the above means cannot be solved from the practicality. That is, in the former case, since the upper edge of the front end of the tread is only displayed in position and the tread surface is not illuminated, the depth of the tread surface is difficult to see at a glance. For this reason, for example, there is a fear of stepping off when the person is not fully awake, such as when waking up during bedtime due to an emergency.

Further, although the tread surface can be illuminated with the latter structure, the tip of the tread is confirmed by the light emitted from the small hole with high illuminance, so that the radiated light is likely to enter the eye when moving up and down. However, there is also the problem that it is difficult to check because of the glare. Furthermore, there is a problem that the small holes are easily clogged with dust or the like, making it difficult to achieve the intended purpose.

[0008]

[Problems to be solved by the device]

 The present invention has been proposed in view of such a point, and it is an object of the present invention to provide a staircase in which not only the end portion of the tread plate but also the entire tread plate is effectively illuminated and which can be safely lifted and lowered.

[0009]

[Means for Solving the Problems]

 That is, this invention forms a hollow illumination space at the front end of the tread along the width direction of the tread, where the front surface is a light-transmissive surface, the inner and upper surfaces are a reflective surface, and the lower surface is an open or light-transmissive surface. The present invention relates to a staircase characterized in that a light source is arranged in the illumination space.

[0010]

[Action]

 According to the staircase of this invention, by turning on the light source, the light illuminates the front end of the tread and the entire lower tread through the light-transmitting surface at the front end of the tread and the opening in the lower surface. Therefore, not only the position of the front end of the tread is confirmed, but also the depth and width of the tread itself are clearly indicated, so that the stairs can be safely climbed up and down even at night. Further, according to the stairs of the present invention, the reflective surface in the illumination space allows the front end of the tread to be clearly displayed without glare, and the entire tread to be effectively illuminated, which is extremely practical. Offered as stairs.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the staircase of the present invention, FIG. 2 is an enlarged perspective view of an essential part thereof, and FIG. 3 is a sectional view thereof.

As shown in FIGS. 1 and 2, the staircase 10 of the present invention is made of wood, concrete, or the like, and is composed of a predetermined number of steps 11 and risers 12. Reference numeral 13 is a non-slip rubber plate provided on the front end portion of the upper surface of the step board 11.

A hollow illumination space 14 is provided below the front end of the tread 11 along the lateral width direction of the tread 11. The illumination space 14 is partitioned by the translucent surface 15, the reflective surface 16 and the opening 17.

The transparent surface 15 is provided at the front end of the tread 11 and forms the front surface of the illumination space 14. The transparent surface 15 is made of an opaque and transparent colored acrylic plate or the like.

The reflective surface 16 forms an upper surface 18 and a rear surface 19 of the illumination space 14. A metal plate or aluminum foil having a smooth surface is attached to one surface of the reflective surface 16, or an appropriate mirror surface treatment is applied to the reflective surface 16 so as to effectively reflect light from a light source 20 described later. Has become.

The lower surface of the illumination space 14 is formed with an opening 17, which has a structure for transmitting light and is convenient for exchanging the light source 20. It should be noted that this opening 17 may be formed by the light transmitting surface described above.

A light source 20 is arranged in the illumination space 14. In this example, a large number of miniature electric balls are arranged at appropriate intervals and are turned on by a switch or the like near the stairs (not shown). The light source 20 may be, in addition to the miniature bulb described above, a fluorescent lamp or a luminous body coated with fluorescent paint.

As can be seen from FIG. 3, according to this staircase 10, the light from the light source 20 illuminates the front surface through the light-transmitting surface 15 at the front end of the tread plate 11 and also through the opening 17 on the lower surface to the lower tread plate. Illuminate 11a. Thereby, not only the front end position of the tread 11 can be clearly shown, but also the depth and width of the entire tread 11 can be easily recognized. Further, as described above, since the upper surface 18 and the rear surface 19 inside the illumination space 14 are composed of the reflecting surface 16, even if the light amount from the light source 20 is small, the front end of the tread and the entire tread 11 are effectively illuminated, and , People who go up and down do not feel glare.

[0019]

[Effect of device]

 As shown and described above, according to the staircase of the present invention, not only the position of the front end portion of the tread plate but also the entire tread plate is illuminated, so that it is possible to move up and down extremely safely. In addition, since the reflective surface is provided in the lighting space, it is possible to effectively illuminate the entire tread even with a small amount of light, and to provide a safe stairway lighting system that prevents glare at low cost. it can.
