Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative structure for a building, and more particularly to a transillumination type decorative device having a structure in which a flexible sheet is covered with a frame containing a lighting fixture.

[0002]

2. Description of the Related Art A decorative structure as shown in FIG. 5 is often used to enhance the decorativeness of a building facing the street.

This shows an example of decoration of the roof portion of a gas station. On the front surface and both side surfaces of the roof 1, a transmitted light type signboard 2 displaying decorative patterns and characters such as trademarks and trade names is attached. In addition, the illumination of the fluorescent tube provided on the back side makes it easy to recognize from a distance at night and enhances the effect of decoration and advertisement.

By the way, as the signboard 2, conventionally, a hard one made of an acrylic plate or the like has been mainly used. In recent years, however, a flexible special synthetic resin sheet has started to be used instead. FIG. 6 is a plan view showing the outline of the signboard structure. The U-shaped frame 3 surrounding the roof part is covered with the sheet 4 so as to cover the open part formed from the front surface to both side surfaces. It is covered. Although the sheet 4 is flexible, it is fixed in a state in which a certain amount of tension is applied by a special clamp at the longitudinal end portion and the upper and lower end portions of the frame 3, so that it has a neat flat appearance. I am doing it.

The frame 3 has a built-in illumination means L including a fluorescent tube along the longitudinal direction so as to be located behind the sheet 4, and the pattern or characters printed on the sheet 4 by the transmitted illumination light. Is clearly visible.

[0006]

However, in such a conventional decorative structure, as shown in FIG. 6, in each portion of the frame 3, the bent portion of the seat 4 is supported from the back surface side thereof to provide an external appearance. In order to arrange the above, a metal support P is attached to the corner in the vertical direction. For this reason, there is a drawback that the illumination light from the illumination means L is blocked by the support columns P, and only the corner portions are darkened.

Further, depending on the shape of the site of the building, the planar shape of the roof corner portion may become an acute angle. In such a case, in the conventional case, the tension force is evenly applied to the bent portion of the seat 4. However, there is a problem that wrinkles occur.

An object of the present invention is to eliminate such conventional problems.

[0009]

In order to achieve the above object, according to the present invention, an opening on one side surface of a frame is covered with a flexible sheet, and the frame is illuminated so as to be positioned behind the sheet. In a decorative structure incorporating means, a supporting member made of a transparent plate-shaped material is provided in a substantially diagonal direction at a corner portion of a frame which is bent and covered with the sheet, and one edge portion forming the corner portion is formed into a curved surface. The bent portion of the sheet is supported from the back side by the one edge portion, and the illuminating means is exposed to the light receiving portion formed of the notch formed inside the supporting member.

[0010]

According to the above-mentioned structure, the transparent plate-shaped supporting member hardly interferes with the light rays from the illumination, and the light incident from the light receiving portion inside the transparent member passes through the inside of the member and reaches the edge supporting the sheet. Therefore, the bent portion of the sheet is kept bright enough to compare with its surroundings.

In particular, since the portion of the support member that supports the bent portion of the sheet is formed into a curved surface, the light from the light receiving portion is well-circulated, and therefore even if the bent portion has an acute angle, a uniform illumination effect is obtained. In addition, since the bending portion is not subjected to excessive force when the sheet is tensioned, wrinkles can be prevented from occurring and a beautiful appearance can be formed.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1 or 2, reference numeral 3 denotes a frame whose plane shape is formed in a U-shape, and the rear and upper and lower surfaces of a frame body 3A assembled as a skeleton made of aluminum extruded material and the like are provided with a reflection plate. Aluminum colored plate 3B that functions as
It is formed by coating with, and the side surface facing outward is open.

The opening portion of the frame 3 is covered with the sheet 4 from both side surfaces to the front surface. The proximal end portion of the seat 4 in the longitudinal direction is fixed in a state where tension is applied by a clamp device as shown in FIG.

That is, the L-shaped angle member 5 welded to the front end of the side surface of the frame 3 is attached to the longitudinal direction (lateral direction) of the seat 4.
A vertical frame portion 6 that supports the tension force is fastened, and the seat end portion 4A guided to the rear side around the vertical frame portion 6 is fastened to the clamp 7.

The amount of advance / retreat of the clamp 7 can be adjusted by a bolt 9 which is interposed between the clamp 7 and the supporting member 8 on the rear side, that is, the seat end 4A with the bolt 9 loosened.
Is fixed to the clamp 7, and then the bolt 9 is loosened and retracted, whereby the seat 4 is appropriately tensioned and the slack is removed.

On the other hand, the upper and lower edges of the seat 4 are also fixed to the upper and lower edges of the open portion of the frame 3 with appropriate tension in the vertical direction through the clips as shown in FIGS. 3 and 4. Has been done.

That is, in FIG. 3 or FIG.
Indicates the clamp portion, and the edge portion of the sheet 4 is fixed to the rear edge portion thereof with the clip 33. A hinge device 22 is a seat plate 22A fixed to the L-shaped angle member 23 horizontally fixed to the upper front end of the frame 3 by a fixing means such as welding or screwing so that the hinge pin 22B is positioned horizontally. And a movable plate 22C rotatably connected to the seat plate 22A via the hinge pin 22B.

The clamp portion 21 is attached to the movable plate 22C via an L-shaped angle member 24 so that the attachment angles are perpendicular to each other. The movable plate 22C and the clamp portion 21 are also fixed to the angle member 24 by welding, screwing or the like. The hinge pin 22B is parallel to the seat 4, that is, at a right angle to the tension direction of the seat 4 (see the arrow T in the drawing).

Numeral 25 is a bolt as a fixing means, which penetrates the angle member 23, the seat plate 22A, the movable plate 22C and the angle member 24 from the rear side of the frame 3 to form the angle member 2
It is fastened to the nut nut 26 welded to No. 4. Instead of providing the nut 26, the angle member 24 or the movable plate 22
A female screw may be formed on C in advance. Reference numeral 27 in the figure indicates a reinforcing member for the frame 3.

FIG. 3 shows a state before the seat 4 is completely attached. As shown in the drawing, the edge portion of the seat 4 is fixed to the clamp portion 21 by using the clip 33 with the hinge device 22 slightly opened. To do. At this time, the seat 4 may be slightly loosened.

After fixing the seat 4 to the clamp portion 21, when the movable plate 22A of the hinge is rotated in the clockwise direction in the figure as it is, the clamp portion 21 is also rotated around the hinge pin 22B to fix the seat 4. Pull the edge parallel upwards.

Next, when the bolt 25 is inserted into the nut 26 and the movable plate 22C is fastened to the seat plate 22A as shown in FIG. 4, the seat 4 is framed in a state in which an appropriate tension acts in the vertical direction. It is fixed at 3.

At this time, the clamp portion 21 has the hinge pin 2
2B, the tension is evenly generated in the longitudinal direction of the seat 4 as the seat 4 rotates.
Is uniformly stretched over its entire length and thus exhibits good flatness.

In this case, the hinge device 22 includes the frame 3
In addition, since the seat 4 can be fixed to the clamp portion 21 in advance, the mounting work of the seat 4 is extremely simple as described above.

Although the upper and lower edges of the seat 4 can be fixed by the clamps 7 as shown in FIG. 1, the long portion has a clamp structure as shown in FIGS. 3 and 4. This makes it possible to exert a stable tension over the entire area, and the work is easy. Further, since the structure is relatively simple, it also contributes to cost reduction.

Next, inside the frame 3 coated with the sheet 4 in this manner, a fluorescent tube 10 as a lighting means is provided.
Is provided. As shown in FIG. 2, the fluorescent tubes 10 are provided in two rows in the vertical direction in order to reduce uneven illumination, and the fluorescent tubes 10 are provided in series in the horizontal direction by the number corresponding to the longitudinal dimension of the frame 3. There is.

In this case, the fluorescent tubes 10 connected in the horizontal direction
Are provided so that the vicinity of their respective electrode portions overlaps each other, thereby compensating for the shortage of the amount of light in the electrode portions, so that a more uniform illumination effect can be obtained.

In addition to the colored plate 3B, the frame 3 is also provided with a reflection plate which is coated with magnesium oxide or the like on its surface so as to face obliquely upward from the rear surface of the fluorescent tube 10 to the front thereof and which has been subjected to diffuse reflection processing. 3C is provided. The reflector 3C reduces the number of fluorescent tubes 10 arranged in the vertical direction and further reduces the uneven illumination on the sheet surface.

A support member 12 made of a transparent plate-shaped material is attached to the corner portion 11 of the frame 3 so as to be located on the diagonal line thereof. This support member 12
Is fastened via a bolt 14 between two flanges 13 raised at the abutting portions of the front surface side portion and the side surface side portion of the frame 3 as shown in FIG. The edge portion facing toward has a curved surface shape as shown in the drawing, and when the frame 3 is covered with the sheet 4, the bent portion of the sheet 4 in the corner portion 11 is supported from the back surface side, and the outer shape of the bent portion is Arrange it into a straight cylinder.

A notch 15 as a light receiving portion is formed in the support member 12 so as to correspond to the height of the fluorescent lamps 10 arranged in two rows. On the other hand, in the corner portion 11 of the frame 3, as shown in FIG. 1, the fluorescent tube 10 located at the front end and the fluorescent tube 1 located at the side front end.
0 and 0 are attached so that their one ends intersect with each other, and one end of the fluorescent tube 10 projecting from the intersecting part is passed through the notch 15.

In the above structure, the transparent plate-shaped support member 1
2 does not easily block the illumination light from the fluorescent tube 10, and the illumination light enters from the end face (cut) of the notch 15 inside thereof.
Since the light ray passes through the inside of the member and reaches the edge supporting the sheet 4, the illumination light reaches the outside even at the bent portion of the sheet. Further, this illumination light is evenly distributed in the circumferential direction because the edge of the support member 12 is a curved surface. As a result, the corner portion 11 is kept sufficiently bright even if it has an acute angle.

The support member 12 is located on the diagonal line of the frame 3, and the resultant force of the tension acting on the front surface side and the side surface centering on the bent portion of the seat 4 is brought into contact with the member surface at the support edge portion. Since the external force does not act in the direction in which the sheet 4 is received in parallel, that is, in the direction in which the plate surface is bent, even if a large tension force is applied to the seat 4, it can be firmly supported.

Further, since the edge portion of the support member 12 has a smooth curved surface shape, even if a strong tension force is applied to the seat 4, an unreasonable force does not act, and therefore, as shown by an imaginary line Q in FIG. Even if the structure has a sharp corner, it can form a beautiful appearance without wrinkles.

The support member 12 does not have to be colorless and transparent, but by applying a lightly colored semitransparent member, it is possible to cause only the corner portions 11 to develop a unique color.

Further, as the light receiving part, the illuminating means may be made to face the rear end face of the transparent plate-like material so that the light is simply incident from the end face of the plate, but as in the above embodiment. An opening notch 15 is provided, and the fluorescent tube 1 is provided inside thereof.
When the illuminating means such as 0 is penetrated, the illuminating means is surrounded by the end surface on which the illuminating light enters, so that the illuminating light can be efficiently taken into the support member 12.

[0037]

As described above, according to the present invention, the bent portion of the sheet is supported by the transparent plate-like supporting members provided in the corner portions of the frame in a substantially diagonal direction, and the fluorescent tube is provided in the light receiving portion provided in the supporting member. Since the illumination light is transmitted through the inside of the supporting member from the opening end face to the edge supporting the sheet through the illuminating means such as, it is possible to keep the bent portion of the sheet sufficiently bright. It has an unprecedented excellent decorative effect.

In particular, in the present invention, since the edge of the supporting member for supporting the bent portion of the sheet is formed by the curved surface, the illumination can be surely distributed over the entire corner even if the corner of the roof is sharp. It is possible to maximize the lighting effect.

Further, since the edge portion of the supporting member is a curved surface, it is possible to support the sheet tension without difficulty, and thus it is possible to prevent wrinkles from being generated and form a beautiful appearance.
