Description

There is an application for exception to loss of novelty

The present invention relates to an interior corridor lighting structure, and more particularly to an interior corridor lighting structure capable of taking in natural light into the internal common corridors of collective housing such as condominiums and the interior corridors of office buildings and the like, which is excellent in terms of the exterior design of the building.

Conventionally, in high-grade condominiums and the like, inner common corridors (hereinafter referred to as inner corridors) are often adopted because they provide quietness and a sense of calmness. In general, interior corridors do not receive external light, so downlights or the like are arranged along the interior corridors to ensure a predetermined level of brightness. On the other hand, since it is not possible to illuminate the entire inner corridor only with lighting such as downlights, there are cases where a feeling of blockage is felt, and there is a demand to take in natural light while maintaining the calmness of the inner corridor. If a lighting structure such as a window is provided on the outer wall side in response to this demand, the inside of the building becomes visible from neighboring buildings, and there is also the problem that privacy cannot be ensured.

In relation to this problem, in order to increase the lighting of the living rooms on the outer corridor side of apartment buildings such as condominiums, there has been proposed a collective housing structure in which bay windows are installed from the living room side to the outer corridor side to ensure the privacy of the living rooms. (Patent Document 1).

In the collective housing structure disclosed in Patent Document 1, a bay window assembly protrudes from the living room side to the outer corridor. This bay window assembly consists of a triangular bay window shape part and a lattice, and the oblique sides of the overhanging triangle are made of translucent frosted glass or glass blocks, ensuring privacy in the living room and facing the outside corridor. It is designed to allow natural light from

JP-A-2002-81218

In Patent Document 1, the disclosed bay window assembly allows natural light from the outer corridor to be taken into the living room, thereby ensuring privacy in the living room at that time. No. Therefore, it is desirable to install a lighting structure similar to a bay window assembly on the exterior wall of the building. In that case, since the bay window assembly disclosed in Patent Document 1 is a structure that is applied to the window portion of each living room, when it is arranged on the exterior of the building, there is a risk that the exterior wall surface of the building will lack integrity and beauty.

SUMMARY OF THE INVENTION Accordingly, the object of the present invention is to solve the problems of the above-described conventional techniques, and to provide an interior corridor with an excellent design appearance that allows natural light to enter the interior corridor while ensuring privacy inside the building. To provide a lighting structure.

In the present invention, an expanded floor is formed by extending a part of the inner corridor to the outer wall side of the building at a predetermined interval in the longitudinal direction of the building, and following the shape of the expanded floor, a part of the outer wall of the building is extended to the building height. A prismatic portion extending in a vertical direction is constructed integrally with the building, and a lighting window corresponding to each floor of the building is provided on one surface of the prismatic portion.

It is preferable that the widened floor has a triangular shape and the prism portion has a substantially triangular prism shape.

It is preferable that the triangular shape is an isosceles right triangle, the two oblique sides of which correspond to the two faces of the prism portion.

It is preferable that the lighting window has a total height substantially equal to the height from the floor surface to the ceiling surface of the inner corridor.

As described above, according to the present invention, it is possible to provide a lighting structure that allows natural light to enter the inner corridors while ensuring privacy inside a building such as an apartment complex, and that has an excellent design appearance. can be realized.

An embodiment of the lighting structure for an inner corridor according to the present invention will be described below with reference to the accompanying drawings.

1 and 2 are a plan view (roof plan) and a front view (entrance) showing the overall shape of a three-story housing complex building 1 that employs an embodiment of the interior corridor lighting structure of the present invention. side elevation) and rear view (outer staircase side elevation). In FIG. 1, a part of the roof 2 is cut away, and a part of the inner corridor 3 and living room 4 are drawn. As shown in FIG. 2 and FIG. 2(a), this collective housing consists of a plurality of one-room type living rooms 4 of approximately the same shape facing an inner corridor 3 extending in the longitudinal direction of the building 1. . As shown in FIGS. 1 and 2(b), on the exterior wall surface 5 of the building 1 on the back side (outside staircase side), an elongated substantially triangular prism-shaped lighting structure 10 is constructed integrally with the exterior wall surface 5. It is As shown in each figure, this lighting structure 10 includes a living room 4A in which both ends of the building 1 partially protrude toward the back side, two external stairs 6, and an elevator installation section 7. It is built in 5 places with a predetermined interval along the direction.

As shown in FIGS. 2(b) and 3, the lighting structure 10 of the present invention has an external shape of a substantially right-angled isosceles triangle in plan view, and a triangular prism shape extending substantially over the entire height of the building 1. It consists of a portion constructed integrally with the building outer wall surface 5, and the surface is finished in the same manner as the other outer wall surface 5. - 特許庁As shown in FIG. 3, the triangular prism-shaped apex 10c has a flattened triangular pyramidal roof shape.

In this embodiment, one wall surface 10a of the two wall surfaces 10a and 10b corresponding to the oblique side of an isosceles right triangle has a lighting window 20 for taking in natural light into the inner corridor 3 of each floor. are provided at approximately equal intervals. In this embodiment, as shown in FIG. 3, each lighting window 20 consists of a two-stage window (hereinafter also denoted by reference numeral 20), the upper window 20U is a single hinged window, and the lower window 20L is a FIX window. It's becoming All windows are made of transparent glass. Further, as shown in FIG. 5, which will be described later, the height of the two-tiered window 20 is approximately equivalent to the height of the inner corridor 3, and the wide range from the floor surface of the inner corridor 3 to the vicinity of the ceiling is possible. The daylighting is sufficient. In this embodiment, the width of the side wall is 800 mm in wall center dimension, and the lighting window 20 having a well-balanced width (for example, about 450 mm) with respect to this width is incorporated. Needless to say, various window dimensions, number of window divisions, window frame types, window opening/closing structures, and window glass types can be adopted as long as they are suitable for the appearance of the building.

Further, in the lighting structure 10 of the present embodiment, as shown in FIG. It is also possible to leave it as it is or not to provide the lighting structure 10 itself on the top floor or the ground floor. On the other hand, it is also possible to provide small lighting windows 20 on both sides of the wall surfaces 10 a and 10 b of the lighting structure 10 .

FIG. 4 is a partial plan view showing a part of the inside of the building and a cross-sectional shape of the lighting structure 10 integrally formed with the building outer wall surface 5, which is a part of the roof 2 cut away in FIG. shows almost the same location as In the figure, two lighting structures 10 are positioned with an outside staircase 6 interposed therebetween. Both of these lighting structures 10 are provided with a two-stage window 20 on the surface facing the center of the building (right side in the figure). For the upper window 20U of the two-tiered window 20, a one-way window that can be opened and closed as shown in the figure is adopted for ventilation of the inner corridor 3. As shown in FIG. Since the glass surface of each lighting window 20 forms an angle of approximately 45° with respect to an adjacent building (not shown), it is difficult to see inside the inner corridor 3 from the side of the adjacent building together with the reflection of the glass surface. This candy ensures sufficient privacy inside the building. In addition, since the light from the lighting window 20 obliquely enters the inner corridor 3 and illuminates the inner corridor 3 brightly over a wide range, the feeling of blockage in the inner corridor 3 is alleviated. Furthermore, the wall surface position of the inner corridor 3 where the lighting structure 10 is provided has a shape following the overhanging widened floor 3a, and has a substantially right-angled isosceles triangular prism shape, and the widened space 12 formed above the widened floor 3a (Fig. In 5), natural light is taken in from the lighting window 20, which further contributes to eliminating the feeling of blockage in the inner corridor 3.

FIG. 5 is a partially developed view partially showing the wall surface of the inner corridor 3 along the arrow line shown in FIG. As shown in the figure, the widened space 12 of the inner corridor 3 of the lighting structure 10 reaches the full height from the floor surface of the widened floor 3a projecting in a triangular shape to the ceiling, and the two-step window 20 extends into the widened space 12. installed over almost the entire height. Therefore, natural light can be sufficiently taken into the inner corridor 3. - 特許庁

FIGS. 6A to 6D show various examples of planar forms of the lighting structure 10 of the present invention. FIG. 6A shows a plan view of the lighting structure 10 shown in FIGS. 1 and 4. FIG. In this lighting structure 10, the oblique side of the triangular shape is about 45° from the side of the inner corridor 3, and the space formed above the widened floor 3a projecting in a substantially right-angled isosceles triangle shape is the widened space 12 of the inner corridor 3. It's becoming On the other hand, the lighting structure 10 shown in FIG. 6B also has an expansion space 12 projecting in a triangular shape. The corridor 3 is about 30 degrees, and the other oblique side where the lighting window 20 is installed is about 60 degrees with the inner corridor 3. By forming the expansion space 12 into such a right-angled triangular shape, the natural light from the lighting window 20 penetrates further into the inner corridor 3, and the closed feeling of the inner corridor 3 is further eliminated. Moreover, since the wall surface of the lighting structure 10 bends and protrudes from the outer wall of the building at a loose angle, an effect that the lighting structure 10 provided on the outer wall surface 5 of the building is less conspicuous can be expected. FIG. 6(c) shows an example in which the lighting window 20 provided in the lighting structure 10 is enlarged when securing privacy from the adjacent building is not so required. In this case, by suppressing the angle formed by the oblique sides on the lighting window 20 side, it is possible to sufficiently take in natural light into the inner corridor 3 while suppressing the influence on the appearance of the building. In the lighting structure 10 shown in FIG. 6(d), the expansion space 12 is about half of the example shown in FIG. 6(a). Since it has a shape that protrudes slightly from the outside of the building, it is difficult to stand out from the outside of the building.

In the above description, an example in which the lighting structure 10 is provided in a collective housing provided in an inner corridor has been described, but it goes without saying that it can also be employed in an office building, a hotel, etc. having the same kind of inner corridor.

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope indicated in each claim. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.
