Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a staircase in which a lighting fixture embedded in the tip of the tread illuminates the staircase surface to prevent people from stepping off the staircase.

[Prior art and its problems]

Generally, in stairs, lighting is provided on the ceiling or on a wall near the ceiling.

However, if such lighting is placed close to the ceiling, the shadow of the upper tread will be reflected on the lower tread, making it difficult to discern the depth of the tread. In addition, the shadows of the upper and lower treads overlapped, making it difficult to distinguish between the tips of the treads, resulting in people often misstepping.

In order to eliminate this kind of danger, for example,
-A proposal has been made to embed lighting equipment at the tip of the tread, as in No. 199909. However, this proposal still has the problem that when a person ascends or descends, the light from the lighting equipment appears in a straight line along the slope of the stairs, making it difficult to see the tips of the treads due to the light emitted from them.

[Means for solving problems and their effects]

The present invention adopts the following configuration in order to solve the above-mentioned dangers of stairs. That is, in the staircase of the present invention, recesses 5 and 8 are formed in the inner surface of the tread 1 in contact with the riser 2 and in the lower floor surface 4 in contact with the lowest riser 2, and the upper tread is placed in the recess 5. A lighting fixture 6 that illuminates the room 1 is housed therein.

In this way, by illuminating the surface of the treadle 1, the present invention can locally illuminate the tip and depth of the treadle 1 in a concentrated manner, thereby eliminating the danger of a person misstepping. It is.

[Description of First Embodiment] An embodiment of the present invention will be described below. First, 1st~
The first embodiment shown in FIG. 5 will be described.

In Figures 1 to 5, 1 is a tread, 2 is a riser, 3 is an upper floor surface, 4 is a lower floor surface, and 5 is a recess provided in the deep part of the tread surface that contacts the riser 2, which is rectangular at the base of the tread. It is provided.
6 is a lighting fixture housed in the recess 5; 7 is the recess 5
The cover is made of a transparent or semi-transparent synthetic resin, and its periphery is placed on the mounting margin 5a of the recess 5.
8 is a recess provided in contact with the lowermost riser board 2 of the lower floor surface 4, and is also provided in a rectangular shape. 9 is the wiring for the lighting equipment. 10 is a reflective mirror surface using a metal coating sheet, metal foil, or the like.

In the embodiment shown in FIGS. 1 to 5, a rectangular recess 5 is provided in the width direction at the back of the tread 1 in contact with the riser 2.

Lighting equipment 6 such as miniature light bulbs and fluorescent lamps is placed in the recess 5.
Several are installed.

Further, although it is not necessary to particularly attach the lighting equipment 6 to the upper floor surface 3, it is desirable to provide a recess 8 in the lower floor surface 4 in contact with the lowermost riser board 2. This is because there is a high probability that the bottom step board 1 will be missed.

In the case of FIGS. 1 to 5, the light from the lighting fixture 6 in the recess 5 is transmitted to the protruding tip 1 of the upper step board 1 as shown in FIG.
Since the front side of the step board 1 is illuminated, it is easy for people going up and down to distinguish the tip of the step board 1, and there is little risk of stepping on it.

In addition, since the recess 5 is made very small and accommodates a small lighting device 6, the stairs of the present invention can illuminate only one part of the tread in a localized manner while keeping the entire passageway dark. Therefore, it does not disturb people's sleep.

The lighting equipment 6 may be a commonly used one such as a light bulb or fluorescent light, and is connected to the wiring inside the recess 2 from the side of the tread, passing through the back side of the stairs or the side wall of the stairs, and installed at the top or bottom of the stairs. Flashing is performed by the switch.

Further, instead of a manual switch, the blinking may be performed by an automatic switch using various sensors such as a proximity switch, a phototube switch, a reflective phototube switch, an infrared switch, or a weight switch.

The inner surface and bottom surface of the recess 5 may be painted or coated with a reflective sheet, if necessary, to form a reflective mirror surface 10.

A lighting equipment cover 7 is provided at the upper part of the periphery of the recesses 5 and 8.
Place it so that it can be removed and placed freely.5
Provide a.

The lighting equipment cover 7 is provided with a finger hook 7a at one corner so that it can be easily removed.

By placing the lighting equipment cover 7, the light from the lighting equipment in the recess 5 does not directly enter the eyes.
The tip of the tread below can be illuminated.

By making the cover removable,
This makes it easy to replace the lighting equipment in the recess 5 or to clean dust that has accumulated in the recess 5.

(Description of Second Embodiment) Next, the second embodiment shown in FIGS. 6 and 7 will be described.

The second embodiment differs from the first embodiment in that the recess 5 is inclined toward the riser 2.

By inclining the recess 5 in this way,
The light from the lighting fixture 6 once hits the riser 2 and is reflected,
The vicinity of the protruding tip 1a of the upper step board 1 is shown.

By once reflecting the illumination light on the riser board 2 in this manner, the depth portion of the lower step board 1 and the tip end portion of the upper step board 1 are illuminated at the same time. Therefore, as a whole, the shadowed portion of the upper step board 1 becomes brighter, and the boundary between the upper and lower step boards 1 can be clearly seen.

However, the light irradiation portion in the second embodiment is substantially the same as that in FIG. 11.

(Other Modifications) Next, some modifications of the present invention other than the above embodiments will be described.

FIG. 8 shows a recess 5 in place of the recess 5 of the first embodiment;
5 are provided separately on both sides of the footboard 1.

9 and 10 show a case where the recess 5 is provided separately into three parts. Figure 10 is - of Figure 9.
A cross section is shown.

[Effect of the invention] As shown in Fig. 11, the surface of the tread plate 1 is also
Since the lighting fixture 6 is attached to the inner surface in contact with the riser board 2 and the lower floor surface 4 in contact with the bottom riser board 2, the light emitted from the lighting fixture 6 is attached to the bottom surface of the riser board 2.
The entire body and the tip of the tread 1 are illuminated from the back side, making the most extreme corner of the tread 1 particularly visible when climbing stairs, and also making it possible to reliably recognize the drop of the stairway, thereby preventing people from stepping off the stairs. It is something to do. Furthermore, when descending from the stairs, the light emitted from the lighting equipment is affected by the difference in brightness caused by the part of the tread 1 that is blocked by the back of the part of the tread 1 that protrudes from the riser 2, and the part that goes straight ahead without being blocked. , the tip of the footboard 1 can be emphasized.

As shown in FIG. 12, the part where the lighting fixture 6 is installed is in the inner part that contacts the riser board 2, so it is a part that is not generally stepped on by shoes when going up and down the stairs, so it can be used for a long time. Since the cover of the lighting fixture 6 is less likely to be scratched and no heavy object is placed on it, there is less risk of damage.
