Description

TECHNICAL FIELD The present invention relates to a shutter device with a screen, which is installed in an opening of a building, a show window, or the like.

[Conventional technology]

The shutter device with the screen is a flexible screen on which decorative photographs, paintings, letters, patterns, and other advertisements are formed on the surface side of a rollable shutter curtain in which a large number of slats are connected. The shutter curtain is provided so as to be able to be wound integrally with or separately from the shutter curtain so that the shutter curtain can be used for a decorative wall surface or a space for advertisement, by means such as painting or attachment of a light emitting body. Compared with the case where the shutter curtain itself is decorated, so-called pattern change has an advantage that anyone can change the pattern easily, easily and quickly, and the technique is already known from Japanese Utility Model Laid-Open No. 58-151293.

[Problems to be solved by the invention]

By the way, the shutter device provided with the screen is only effective from the evening to the night, and generally, in order to enhance the decorative property of the screen and the effect of the advertisement, the direct light is applied to the upper part or the side part of the shutter curtain. Lighting equipment is provided.

However, it is extremely difficult to illuminate the entire screen evenly, and it is difficult to identify the pattern because strong light is reflected on the screen part near the light source, and conversely, the screen part away from the light source becomes dark. There was room for improvement in terms of decorativeness and advertising effects.

Alternatively, it is technically difficult to emphasize and illuminate a specific area of the screen.

The present invention was devised in view of the above situation, and by extremely simple and rational improvement, uniformly illuminates the screen in a planar manner, or emphasizes a specific range of the screen. The purpose is to provide a technique that can be illuminated.

[Means for solving problems]

In order to achieve the above object, the first invention of the present application is to provide a flexible screen on which a photograph, a painting, a character, a pattern or the like is formed, on the surface side of a retractable shutter curtain or integrally with the shutter curtain. A shutter device provided with a screen that can be separately wound, wherein the screen has a light-transmitting property, and a light source is provided on an end side of the shutter curtain, and light from the light source is provided on an end surface. The shutter curtain is provided with an optical transmission member that receives light from a front surface and projects the light from the front surface to the back surface side of the screen, and the optical transmission member arranges a large number of optical fibers in parallel to project light in a planar manner. There is.

Further, the second invention of the present application makes it possible to wind a flexible screen on which photographs, paintings, characters, patterns, etc. are formed, on the surface side of the windable shutter curtain, integrally with the shutter curtain or separately. A shutter device provided with a screen provided, wherein the screen has a light-transmitting property, and a light source is provided on an end side of the shutter curtain, and light from the light source is received by an end surface portion of the surface. Is provided on the shutter curtain, and the light transmission body is a substantially flat plate and is a light emitting plate that projects light in a planar shape.

[Action]

According to the above characteristic configuration, the light projected from the light source toward the end face portion of the light transmission body is projected on the back surface side of the screen in a planar manner through the light transmission body and is transmitted through the screen. The screen is illuminated from the back side.

Then, by dispersing the light projecting surface portion of the light transmitting body in a predetermined manner, the predetermined surface portion of the screen is evenly illuminated, or the light projecting surface portion of the light transmitting body is made dense, or By increasing the light amount of the light source with respect to the light transmission body, a specific range of the screen is emphasized and illuminated.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a left half of a shutter device B provided with a screen device A, and the shutter device B includes a building opening 1
A guide rail 3 is embedded in a side wall 2 of the shutter, and a shutter curtain 6 formed by connecting a large number of slats 4 ... Further, a curtain winding device (consisting of a drum 8 and a drive mechanism 9 incorporated in the case 7) for winding the shutter curtain 6 upward is provided.

On the other hand, the screen device A is composed of a screen 11 having flexibility and translucency of a size that covers the entire surface of the shutter curtain 6, and a drum 12 for winding the screen 11 upward, and The drum 12
Is built in the screen case 13, and the lower end of the screen 11 is attached to the lower seat plate 5 of the shutter curtain 6.
And is configured to be wound separately from the shutter device B.

In the illustrated example, an ornamental object (for example, a photograph, a painting, a letter, a pattern, or the like, which may be an advertisement, etc.) C is attached or printed on the intermediate portion on the front surface side of the screen 11. The shutter device B is provided with a lighting device 14 in order to enhance the decorativeness of the decoration C at night.

As shown in FIG. 2 to FIG. 5, the illuminating device 14 wraps a strip-shaped optical transmission body 16 formed by joining a number of optical fibers a in parallel with a double-sided tape 15 on the ornament C. Along the entire length of the slat 4 is attached to the surface side via the double-sided tape 15, and the portion of the light reflection coating b of the light transmission body 16 that is wrapped with the decoration C is scraped off. Peeling off the optical transmission body 1
6, a light projecting surface portion d for projecting the screen in a planar shape is formed, and a light source 17 for projecting light to both end surface portions of the light transmission body 16 in the extended state of the screen 11 is provided inside the guide rail 3. It is provided.

Therefore, when light is projected from the light source 17 to both end surfaces of the light transmission body 16 while the screen 11 is stretched, the light is reflected on the inner surface of the light reflection coating b and is emitted from the light projection surface portion d. Light is projected toward the back surface side of the screen 11, and thus the entire ornament C formed on the translucent screen 11 is uniformly illuminated from the back surface side.

In addition, by dividing the light source 17 into a plurality of light sources in the vertical direction and changing the light amount of each light source or changing the light amount, the specific range of the ornament C can be emphasized and illuminated. Alternatively, the specific range of the ornament C can be emphasized and illuminated by partially increasing the number of optical fibers.

In addition, in the structure in which the light source 17 is divided into a plurality of parts,
The decorative effect can be further enhanced by blinking the predetermined light sources 17 or projecting light of different colors from the respective light sources 17.

Further, the end face portion of the optical transmission body 16 may be bent and the light source 17 may be provided so as to correspond to the end face portion.

Next, another embodiment of the shutter device B with a screen will be described with reference to FIGS. 6 to 8. This example shows an example in which a screen 11 is provided in the middle part of the shutter curtain 6 and the screen 11 can be wound up integrally with the shutter curtain 6, and the upper edge of the screen 11 is used as the shutter curtain 6. The locking members 1 that are fixed to the left and right sides of the screen 11 and the shutter curtains 6 corresponding to the left and right sides of the screen 11 are arranged in a zigzag pattern at upper and lower sides at a predetermined interval.

The string-like body 20 fixed to the above is inserted from the upper side of the locking members 18 and 19 to the lower side one by one, and the spring 21 is connected to the lower end of the string-like body 20. The other end of the slat 4 is fixed to the lower seat plate 5 of the shutter curtain 6, and spacers 22 are provided on both ends of the slat 4.

According to the above configuration, the pitch dimension of the arc-shaped slat 4 when the shutter curtain 6 is wound is
It becomes larger than the pitch dimension of the slat 4 when it is linear, and when the screen 11 is directly adhered to the shutter curtain 6, it is impossible for the screen 11 due to the difference in the pitch dimension. Although the screen 11 is peeled off or damaged due to various tensions, the above-mentioned inconvenience can be avoided by absorbing the difference in the pitch dimension by the spring 21.

Since the spacers 22 are provided at both ends of the slat 4, the screen 11 and the light transmission body 16 are not sandwiched between the wound slats 4 and 4.

Illumination device 14 equipped in shutter device B having the above-described configuration
In the description, the light emitting plate (for example, a light emitting plate that forms an opening 23 in the portion of the slat 4 that wraps with the screen 11 and projects the light received at the end face portion from the surface portion on one side in the thickness direction (for example, A light transmission body 16 made of a product name of Meitaku System Co., Ltd .; a light emitting panel) is provided over the entire width of the slat 4 in a state in which the opening 23 is closed from the rear surface side of the shutter curtain 6, and The light emitting surface other than the portion facing the opening 23 of the transmission body 16 is covered by, for example, vapor deposition of aluminum as shown by the symbol e, and the strength and fire resistance are reduced by forming the opening 23 in the slat 4. Therefore, a reinforcing member 24 having a U-shaped cross section is provided over the entire length of the slat 4, and the spacer 22 is attached to the reinforcing member 24 while the screen In tensioned state of 11 made by providing a light source 17 for projecting on one end face of the plate-shaped light transmission body 16 (or across surface) inside the guide rail 3.

Therefore, when light is projected from the light source 17 to both end surface portions (or one end surface portions) of the light transmission body 16 while the screen 11 is stretched, the light is emitted from the light projecting surface portion d except the aluminum vapor deposition surface portion e. Light is projected to the back surface side of the screen 11 through the opening 23, and thus the entire screen 11 having the light-transmitting property is evenly illuminated from the back surface side.

Although the light transmission body 16 is provided over the entire length of the slat 4, the light transmission body 16 is provided only in a range extending from one end of the slat 4 to the opening 23.
Light may be projected from the light source 17 onto the surface portion on the one end side of 6.

Further, the light projecting surface portion d of the optical transmission body 16 facing the opening 23.
Alternatively, aluminum may be partially vapor-deposited to form a non-light-transmitting portion, and the screen 11 may be illuminated with uneven brightness.
