DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting stair which is suitably used as an inner stair of a detached house and a method of constructing the stair.

[0002]

2. Description of the Related Art
As lighting stairs suitably used as inner stairs of a detached house, Japanese Utility Model Laid-Open Nos. 54-94012 and 58-11
No. 801, No. 2-40835 and No. 7-1
No. 6840 is known. Each of these illumination stairs has a light source provided on the lower surface of the step nose of the step plate, and illuminates the step plate below the light source.

However, Japanese Utility Model Application Laid-Open No. 54-94012
No. 2-40835 and No. 7-1684
As shown in No. 0, when a light source accommodating recess is formed on the lower surface of the nosing portion of each step plate and a light source is accommodated in the light source accommodating recess, the thickness of the nosing portion of the step plate is reduced by the amount of the light source accommodating recess. There is a problem that the thickness becomes thin and the strength of the nose decreases.

In addition, as shown in Japanese Utility Model Laid-Open No. 58-11801 and Japanese Utility Model Laid-Open No. 7-16840, when a light source cover is provided in front of a light source provided on the lower surface of the nosing portion of each step board. However, there is a problem that the foot of a person climbing the stairs may contact the light source cover and damage the light source cover.

Further, as shown in Japanese Utility Model Laid-Open No. 54-94012, Japanese Utility Model Laid-Open No. 58-11801 and Japanese Utility Model Laid-Open No. 7-16840, a light source is provided on the lower surface of the nosing portion of each step board so as to point vertically downward. In such a case, there is a problem in that illumination is performed mainly on the base end of the step plate immediately below the light source, and the end of each step plate is hardly illuminated.

On the other hand, in addition to the above-described lighting steps,
Illumination stairs such as shown in 0-269841 are known. This lighting staircase has a light source on the lower surface of the nosing part of each stepboard at a certain angle with respect to the stepboard so that the tip of the stepboard is dark and the other parts are brightly lit when viewed from the direction of descending the stairs. It is provided in such a manner. According to this, since the light source is provided directly on the lower surface of the nosing portion without forming the light source accommodating concave portion on the lower surface of the nosing portion, the strength of the nosing portion of the step plate does not decrease. In addition, since the light source cover is provided at a certain angle with respect to the step board, the foot of a person climbing the stairs is prevented from contacting the light source and the light source cover.

However, in this lighting staircase, the tip of the step board is dark and the other part is brightly illuminated when viewed from the direction of descending the stairs. If the part is dark, it is rather difficult to see the stairs. In addition, if only the light source or the light source cover is provided in an exposed state on the lower surface of the step nose of each step board, there is a problem that the appearance is poor when viewed from the direction of ascending the stairs.
Furthermore, the lower surface of the step nose of each step board requires a cosmetic finish because it can be seen from the direction of ascending the stairs, but in this lighting staircase, a decorative finish must be separately applied to portions other than the portion where the light source is provided. There was also a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an illuminated staircase which illuminates a step surface of a staircase preferably over a wide area and has excellent strength, appearance, and safety. And

[0009]

In order to achieve the above object, according to the present invention, a nose cover of a stair plate of a stair is provided, and the nose cover corresponds to an upper surface of the nose of the step plate. A horizontal portion, a vertical portion extending downward from the horizontal portion and corresponding to the tip of the nosing portion, and an inclined portion extending obliquely downward from the lower end of the vertical portion toward the back surface; One or a plurality of light sources are provided to the portion obliquely downward.

According to this, one or a plurality of light sources are provided obliquely downward on the inclined portion of the nose cover, so that the step plate surface below the light source of the stairs can be suitably illuminated over a wide area. can do. Further, since the light source is provided integrally with the nosing cover, the strength of the nosing portion can be maintained without the necessity of forming a light source accommodating recess in the nosing portion. Also, the nostril cover provided with the light source,
Since it covers the lower part of the nosing part and the contact part between the step board and the riser,
It is not necessary to separately apply a decorative finish to the lower surface of the stepped nose or to compensate for an assembling error of the contact portion between the stepped plate and the riser plate, and a good aesthetic feeling can be easily and reliably secured. Furthermore, since the slope of the nostril cover provided with the light source extends obliquely downward from the lower end of the vertical portion toward the back side, the toe of a person climbing the lighting stairs may have the slope of the nostril cover. And no contact with the light source, thereby preventing damage to the inclined portion of the nostril cover and the light source.

Preferably, the light source is a light emitting diode. According to this, since the light emitting diode can be used semi-permanently, there is no need to perform maintenance, and power consumption is low and economical. In addition, since the light-emitting diode generates little heat, high-temperature damage such as thermal deformation can be prevented, and moreover, it is possible to produce a softer illumination than other light sources such as a light bulb.

Preferably, the inclined portion of the nasal cover extends obliquely downward from the lower end of the vertical portion toward the rear surface at an angle of 33 to 70 degrees with respect to the horizontal portion. . According to this, it can be applied to all normal stairs.

It is desirable that the nostril cover is made of a hard elastic synthetic resin. According to this, the nose cover can be easily and securely attached to the nose portion of the step board by its elastic force.

On the other hand, the method of constructing the lighting stairs for transforming the existing stairs into the lighting stairs includes a horizontal portion corresponding to the upper surface of the nosing portion of the step board of the existing stairs, and a lower portion extending from the horizontal portion to correspond to the tip surface of the nosing portion. Having a vertical portion, and a slant portion extending obliquely downward from the lower end of the vertical portion toward the back side, and one or more light sources being provided on the slant portion so as to point diagonally downward. The cover is attached to the nosing portion of the stepboard of the existing staircase, and the decorative plate is arranged on the upper surface of the region excluding the nosing portion of the stepboard such that the upper surface is flush with the upper surface of the horizontal portion of the nosing cover. It is characterized in that it is installed.

According to this method, the existing staircase can be easily and reliably remodeled into a lighting staircase. In addition, since the upper surface of the horizontal portion of the nasal cover and the upper surface of the decorative board are flush with each other, the appearance is excellent. Note that the same plane in the present invention includes not only a completely flush state, but also a state in which a slight step is formed between the upper surface of the horizontal portion of the nosing cover and the upper surface of the decorative plate.
