Description

  The present invention is a blindfold sliding door that is installed inside a glass window or the like of a building to prevent the room from being looked into from the outside, and light is emitted into the room even when the sliding door is closed. It can be guided and the room is not dark.

In a building, a shutter and a curtain are used as a means for preventing the room from being looked into from the outside through the window glass.
The shutter is installed outside the glass window and has functions such as storm, shading, and soundproofing, and also has a crime prevention function of preventing the window glass from breaking in.
The curtain is installed on the indoor side of the window to prevent light shielding, soundproofing, and peeping, and has a function of softening the light entering the room by making the curtain material translucent.

The shutters are installed outside the windows of the building, so it is cumbersome to open and close the shutters when opening and closing, and there is a large temperature difference from the room in winter and summer Therefore, outside air having a large temperature difference enters the room that is adjusted to a comfortable state, and wasteful energy is required to restore the room temperature. In addition, the person who performs the opening / closing operation may feel uncomfortable because it is exposed to a rapid temperature difference. Although an electric shutter has been proposed for automatically opening and closing windows from the room, it requires a power source and is expensive.
Curtains can be opened and closed indoors, but the curtains are generally made of cloth and require regular maintenance such as washing regularly. Not to say

In order to compensate for the shortcomings of shutters and curtains, it has been proposed that suspension type sliding doors are arranged in a straight line on the indoor side of the building to solve privacy protection such as shading, soundproofing, and peep prevention at once.
On the other hand, various technical means for guiding natural light into the room have been proposed.

JP 2007-115646 A

However, if priority is given to the light shielding and soundproofing properties of the hanging slide door, no light enters the room at all, and the room is completely dark.
In order to introduce light into the room, if the gap for introducing the light is opened by moving the suspension type sliding door halfway, it becomes unsightly when viewed from the outside. Moreover, it is troublesome to open all the sliding doors by opening all the hanging type slide doors.
In view of this, the present invention enables a certain amount of light to be guided indoors in a closed state without opening the suspension type sliding door.

A space is formed between the outer surface plate and the inner surface plate of the suspension type sliding door, and a slit is provided at the edge of the outer surface plate. A light reflector that reflects toward the surface is provided in the space between the outer plate and the inner plate along the slit, and an opening is provided in the center of the inner plate, and a semi-transparent member is provided in the opening. It is a light slide door.
A space is formed between the outer surface plate and the inner surface plate of the hanging type sliding door, and a slit is provided at the edge of the outer surface plate, and a light scattering sheet is provided in this slit, and light incident on the slit is provided. A light scattering sheet for scattering toward the center part is provided, and an opening is formed in the center part of the inner surface plate, and this opening is a light guide slide door provided with a translucent body.

Light incident on a slit provided at the edge of the outer surface plate on the outside of the hanging slide door is reflected by the light reflector to the center of the slide door and is emitted from the indoor opening at the center of the slide door. Can be guided indoors, and natural light can give a certain level of brightness to the room.
In addition, by providing an opening / closing body that can be operated from the room, the slit can block light and prevent light from entering the room.

<Example>
FIG. 1 is a front view of a hanging slide door 1 according to the present invention, showing an indoor side and an outdoor side. The door 1 has a rectangular frame formed of a frame material 2, and an inner surface plate 31 and an outer surface plate 32 are fixed to both front and back surfaces of the frame, and a space S is formed between the inner surface plate 31 and the outer surface plate 32. Has been.
An opening 4 is provided in the inner surface plate 31, and a translucent body made of reinforced shoji paper, Japanese paper, lace, thin fabric, or the like is provided in the opening 4 as a light surface 42.

FIG. 2A is a cross-sectional view of a portion of the door 1 without a handle, and FIG. 2B is an exploded cross-sectional view thereof. FIG. 2C is a cross-sectional view of the handle 52 portion.
A light reflector 41 such as a light reflecting sheet for reflecting light or a thin metal plate is attached to the side of the outer plate 32 facing the space S. A light reflection coating film may be formed by applying a light reflection paint instead of attaching the light reflector 41. The surface of the light reflector 41 may be a concavo-convex surface so that light is irregularly reflected without making it a mirror surface.

  Longitudinal slits 45 are formed at both end portions of the outer plate 32, and the width of the slits 45 is about 20 to 30 mm. Facing the slit 45, the space S is provided with an inclined or curved light reflecting surface 40. The light reflecting surface 40 is provided on the support body 15 extending in the longitudinal direction installed at a position facing the slit 45.

  The external light incident from the slit 45 is reflected by the reflective surface 40 toward the center of the door 1 in the space S, reflected or scattered by the light reflector 41 provided on the external plate 32, and the optical surface of the opening 4. Since 42 is illuminated, the light surface 42 is brightened with soft light.

A light receiving body (not shown) is installed instead of providing the reflecting surface 40 at the position facing the slit 45, and a light guide body such as an optical fiber is attached to the light receiving body, and the light guide body is a light reflector 41 at the center of the door 1. May be guided to illuminate the light surface 42.
Instead of providing the reflecting surface 40 facing the slit 45, the central portion side of the door 1 is formed by a daylighting film described in a film (for example, JP-A-2014-235369) that scatters external light incident from the slit 45 in a specific direction. The incident light may be scattered.

Alternatively, a horizontally long slit 45 is formed at the top of the door and a horizontally long opening is formed at the top of the inner surface plate 31 to scatter incident light on the ceiling side of the room. It is also possible to scatter incident light on the ceiling of the room.
A slit 45 having a width of 30 to 50 mm is provided on the upper side of the hanging door 1 in the lateral direction of the door, and a daylighting film that scatters light in a specific direction is installed in the slit 45. Since this daylighting film can adjust the scattering direction of incident light, a daylighting film suitable for the direction to be brightened is used.

A shutter 5 for blocking the entrance of external light from the slit 45 is provided in the internal space of the door 1.
As shown in FIG. 3 (1), the shutter 5 is guided by guide rails 51 provided above and below the interior space of the door 1 and slides to the left and right to open and close the slit 45 to allow outside light to enter the indoor side. It is something that prevents or stops.

As shown in the sectional view of FIG. 3 (2), the side end portion of the shutter 5 is bent for reinforcement except for the upper and lower end portions guided by the guide rail 51.
FIG. 3 (3) is a sectional view of the door 1 at the position of the handle 52, and a blade 53 is provided so that the inside of the door 1 cannot be seen from the handle opening 33 of the inner surface plate 31. As shown in (4), the size is larger than the size of the handle opening 33 indicated by the dotted line.

As shown in FIG. 1B, the handle 52 of the shutter 5 is positioned in a handle opening 33 provided in the inner surface plate 31. By moving the handle 52 left and right, the shutter 5 is guided by the guide rail 51 to be in the space S. The slit 45 is opened and closed by sliding left and right inside.
As shown in FIG. 2 (3), the frame member 2 and the support 15 have a cut space 20 in which the blades 53 are accommodated when the shutter 5 moves to the left and right.
