Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to an illuminated staircase, and more specifically, to an illuminated staircase in which a stair handrail is provided with an illumination section that illuminates the stair steps and the like.

<Conventional technology> In recent years, there has been a trend toward higher quality indoor furnishings such as furniture, and with this trend, stairs are also being used that have a dignified appearance that is comparable to the furnishings. . By the way, in order to give such a profound feeling to the staircase, methods are generally used such as using a material with a deep dark color or painting the surface with a dark wood grain finish, for example.

<Problem that the invention aims to solve> By the way, finishing the surface in a dark color like this can be said to be very effective in creating a sense of solidity, but it is not desirable from the perspective of ensuring the safety of stairs users. I can't say that. This is because the surface of such stairs is dark colored, making it difficult to clearly see the separation between the steps and the landing or the upper and lower floors. For this reason, when there is no lighting at night, users may trip over the risers of the steps that touch the lower floor or the top of the landing when climbing the stairs, or may mistake the landing for a tread. It's easy to lose your balance. Furthermore, when descending the stairs, it becomes difficult to see the boundary between the upper floor surface and the step section, or the boundary between the landing and the tread, which increases the risk of injury from stepping off the step. This tendency is particularly noticeable when a material with many lines appearing on its surface, such as laminated wood, is used as the material for the stairs.

<Means for solving the problem> The lighted staircase of this invention, which was devised in view of the above problems, is made of a base material with a dark-colored surface, and includes a relatively thin child pillar and a relatively thick main pillar. In the staircase having a handrail section, a lighting fixture is provided inside the main pillar, and a part of the surface of the main pillar facing the step part is made transparent or translucent.

<Function> The main pillar as described above is normally used as a handrail support located at a step joint between a tread and a landing of a stairway, or between an upper and lower floor surface and a tread. By using the above-mentioned means, this step joint portion can be made brighter, so that stair users can easily and reliably see this portion even at night.

<Example> Fig. 1 shows a step part 1 consisting of a tread 1a and a riser 1b, the surface of which is finished in a dark tone, with one side facing a wall 2 and the other side facing a handrail 3. This shows an example in which the present invention is applied to facing stairs. In the same figure, handrail part 3
is composed of main pillars 4, 5, and 6, a large number of child pillars 7 provided between the main pillars, and a handrail 8 supported by these pillars.

A known illumination means (not shown) comprising a light bulb or a fluorescent light is built in the main pillars 4, 5, or 6, and the step portion facing surface of the main pillars 4, 5, 6 or Lower surfaces 4a, 4 of upper and lower floors facing each other
b, 5a, 5b, etc. are composed of transparent glass plates, frosted glass plates, transparent plastic plates, semi-transparent plastic plates, etc., and the illumination light inside the main pillar is transmitted through these lower surfaces 4a, 4b, 5a, 5b. are located near the lower surface of the tread 1a and the riser 1
b, the landing 1c, the lower floor surface 9, the upper floor surface 10, etc. are illuminated. The other parts of the main pillars 4, 5, 6, the child pillar 7, or the handrail 8 are finished in the same color as the step part 1.

FIG. 2 shows the step part 12 at the lower floor of the staircase.
This figure shows an example in which the present invention is applied to a staircase in which both sides face the handrail part 13. In the figure, the main pillars 14, 15, and 16 are each equipped with known illumination means (not shown) inside the main pillars 14, 15, and 16. The lower surfaces 14a, 14b, 15a, 15 which are the surfaces facing the steps or the surfaces of the upper and lower floors are built-in.
b, 15c, etc. are constructed of transparent glass plates, etc., as in the previous embodiment.

<Effects of the invention> According to the illuminated staircase of this invention constructed as described above, the step joints such as between the treads of the stair step portion and the landing or between the upper and lower floor surfaces and the treads can be brightened. Since this part can be easily and reliably seen by the stair users, it is possible to prevent stair users from tripping on the steps at night, etc., and to ensure their safety. . In addition, the above-mentioned transparent or semi-transparent parts provided on the main pillars serve as a kind of accent and improve the quality of the entire staircase, which also has the advantage of increasing the high quality value of the stairs.
