  As described above, the windows described in the conventional patent documents 1 to 3 have a problem that the sunlight deflected in the direction of the ceiling is significantly reduced when the two doors overlap.

  That is, a door provided with a light control member that applies refraction, reflection, etc. as a result and deflects incident light from above upward and emits the light functions effectively as it is alone, and deflects outside light toward the ceiling Thus, the indoor space is made to be bright, and the lighting efficiency is improved.

  However, when two light control members for deflecting incident light from above upward and emitting them are used in a stack, the light amount deflected upward for emission is significantly reduced and the desired effect can not be obtained.

  As a general window, a so-called sliding door is known which is opened and closed by pulling two doors, which have overlapping movements on two rails or grooves, to the left or right. In the sliding door, when the door is opened, the two doors overlap. Therefore, in the case where a light control member for deflecting incident light from above upward and emitting it to such a sliding door is applied, in the state where the window is opened (the door is overlapped), the light is deflected toward the ceiling The problem is that there is a problem that the light to be used is greatly reduced to make the indoor space feel bright and the effect of improving the light collection efficiency is greatly reduced.

  The present invention has been made in view of such a situation, for example, when used as a sliding door, when the window is opened, that is, a state in which the first door and the second door overlap. It is an object of the present invention to provide an openable window having a high light collecting effect by the light control member.

In view of the above situation, the research and development are advanced, and the first aspect of the present invention is an openable window, wherein the window is a first door and the first door when the window is opened. And a second door installed side by side with the first door when the window is closed, the first door and the second door each including: A pattern of a light control unit for deflecting light incident from one surface of the door and emitting it from the other surface facing the one surface of the door, and a non-formed portion of the light control unit are provided. While moving the second door from a first position installed most overlapping with the first door to a second position installed side by side with the first door, Alternatively, the second door is installed in any of a third position and a fourth position which are different from each other along the first door. If the first position can be installed in the most overlapping position with the first door, any of the third position and the fourth position can be installed side by side with the first door. The window is an open / close window that does not have a portion where the patterns of the light control portions of the first door and the second door overlap with each other while being moved toward the key position .

  According to the invention described in the present invention, for example, when used as a sliding door, when the window is opened, that is, even when the first door and the second door overlap, the light deflection portion Provide an openable window with a high lighting effect.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments at all, and can be implemented with appropriate modifications within the scope of the object of the present invention. The drawings are conceptual diagrams, and the scale relationships, aspect ratios, and the like of components may be exaggerated as appropriate depending on the convenience of the description.

  In the present embodiment, for convenience, the X-axis direction shown in the drawings is the left-right direction (especially the arrow direction is right), the Y-axis direction is the up-down (especially arrow direction is up), the Z-axis direction is back and forth (especially arrow direction) Will be called later). With reference to the opening / closing window 1, the arrow direction of the Z axis is referred to as the incident light side or the outdoor side, and the direction opposite to the arrow direction of the Z axis is referred to as the outgoing light side or the indoor side.

  The front view corresponds to the plane direction from the incident light side (outdoor side), a plane parallel to the XY plane, or the planar doors 2 and 3 when viewed from the whole and on a large scale It is a drawing obtained when observing a surface (surface parallel to the XY plane), in other words, a drawing showing a shape viewed from the normal direction (Z-axis direction) erected on the doors 2 and 3 parallel to the XY plane. It is.

  In the present embodiment, a window is an opening provided on a wall surface provided for the purpose of daylighting, and is used as a word indicating what is separated from the external world by a light transmitting plate such as glass, resin, or shoji. If it is accompanied by a function, it is used as a broad concept including an opening as a passage through which people can go in and out, a so-called door and a door.

  In the present embodiment, the openable window 1 is installed so as to overlap the first door 2 when the openable window 1 is opened, and is closed when the openable window 1 is closed. And a second door 3 installed side by side with the door 2. Typically, one of the sliding doors can be exemplified by a sliding door of a type in which two doors are pulled to either the left or the right on two rails or grooves. This also applies to a sliding door or the like having an appearance in which two sets of sliding windows are arranged side by side. Furthermore, it may be a sliding door of a type in which three doors are pulled to the left or right on two rails, a groove, or three rails, or a groove.

  Each of the doors 2 and 3 has a light transmitting plate 10 having a pattern 11 of a light control portion which is a forming portion of the light control portion, and has a window frame for holding the light transmitting plate 10 as necessary. It may be equipped with a handle, crescent lock, auxiliary lock, decoration, etc.

  The light transmitting plate 10 is made of a material that transmits light. The light transmitting plate 10 may be made of a single material, or may be a composite material made of a plurality of different materials. The most typical example corresponds to a window glass when the door is a glass window. Besides glass, a plate material made of a transparent resin material or the like may be used, or paper like a shoji may be used. Moreover, the board | plate material which consists of these composite materials may be sufficient. Furthermore, it may be made of a plurality of plates via an air layer or vacuum as in a double glass window.

  The light control unit is a portion having a function of deflecting light incident from one surface of the doors 2 and 3 and emitting the light from the other surface. The light control unit is integrally formed with the light transmission plate 10 constituting the doors 2 and 3, and the light transmission plate 10 itself may have a function as a light control unit. Alternatively, a light control member having a function as a light control unit may be provided.

  As means for deflecting light, many means are known, such as utilization of a reflective material, utilization of a material whose refractive index differs continuously or discontinuously, and utilization of a prism structure or a lens structure.

  As an example, it is formed on the glass window which is the light transmission sheet described in patent document 3 as the pattern 11 of the light control part which is the formation part of the light control part, and is formed on the glass plate which is the light transmission plate 10 Explain.

  FIG. 17 is a cross-sectional view for explaining a use state of the daylighting sheet 30 as an example of the light control member forming the pattern 11 of the light control unit according to the embodiment of the present invention.

  The daylighting sheet 30 is used by being held along the window glass 31 which is the light transmitting plate 10, deflects the optical path of the sunlight incident on the window glass upward, and guides it to a ceiling or the like where direct sunlight does not enter. More specifically, the daylighting sheet 30 is used by being attached to the surface on the indoor side of the window glass 31 via the adhesive layer 32. For this reason, the daylighting sheet 30 is composed of a lens layer 34 for bending the light path of sunlight, and a base layer 33 for holding the lens layer 34 is provided on the outdoor side of the lens layer 34. It is stuck on the window glass 31 by the adhesive layer 32 provided on the outdoor side of 33 and held. Further, on the indoor side of the lens layer 34, a protective layer 36 for protecting the lens layer 34 is provided.

  For the substrate layer 33, a transparent sheet substrate made of, for example, PET (polyethylene terephthalate) resin is applied. In the daylighting sheet 30, a concave groove 35 is formed on the surface of the transparent sheet substrate. Here, the concave groove 35 is a surface facing the upper side (consistent with the upper side in FIG. 17 and the other figures of the crucible) and a surface facing the lower side (consistent with the lower side in FIG. And is formed by connecting a pair of slopes, and in this embodiment, it is produced by a groove having a wedge-shaped cross section. The daylighting sheet 30 is manufactured such that the concave groove 35 linearly extends, and is stuck to the window glass 31 and held so that the extension direction is horizontal. The recessed grooves 35 are repeatedly produced at a predetermined pitch in a direction (vertical direction, which corresponds to the vertical direction in each drawing) orthogonal to the extension direction.

  The concave groove 35 applies an ultraviolet curable resin on one surface of the base material layer 33, and then presses the transfer mold to cure the ultraviolet curable resin by irradiation of ultraviolet rays, thereby the mold for transfer. It transfers and produces the uneven | corrugated shape produced by this. The method of manufacturing the concave groove 35 is not limited to this, but, for example, when the concave and convex shape of the mold is transferred by pressing the transfer mold in a state where the transparent sheet material such as polyvinyl chloride is heated and softened. Etc., various techniques can be widely applied.

  The light collecting sheet 30 is filled with the filling material 38 in the concave groove 35, whereby at least the upper surface of the upper and lower surfaces of the concave groove 35 is made to have a reflective surface 39. The sunlight L1 and L2 are reflected and the light path of the sunlight L1 and L2 is bent. Specifically, in this embodiment, as the filler 38, a so-called mirror ink in which a powder of high reflectance by aluminum, silver or the like is dispersed in a binder by a transparent resin material is applied. Further, as the binder, for example, an ultraviolet curable resin, a thermosetting resin or the like is applied. Therefore, after the filler 38 is filled in the concave groove 35, the daylighting sheet 30 is cured to produce the lens layer 34.

  Note that white ink may be applied to the filler 38 filled in the concave groove 35, and in this case, the light emitted from the light collecting sheet 30 can be scattered light. Alternatively, a colorless and transparent ink may be applied, and in this case, the refractive index with respect to the refractive index of the transparent material constituting the concave groove 35 causes total reflection to occur on at least the upper surface of the concave groove 35. Materials with small rates are selected. Also, black ink or various colored inks may be applied. In this case, a binder of a pigment according to coloring is used as a transparent resin material, and a transparent resin having a smaller refractive index than that of the transparent material forming the concave groove 35 The material is selected. Thus, when using black ink and coloring ink, it can set so that daylighting sheet 30 itself may take on a desired color, and can make daylighting sheet 30 excellent in design.

  The light collecting sheet 30 is subsequently coated with an adhesive to provide an adhesive layer (not shown), and the protective layer 36 may be disposed by the adhesive layer. In addition, a hard coat film may be provided on this protective layer 36. The protective layer 36 and the hard coat film are provided in order to prevent damage to the daylighting sheet 30 in cleaning work and the like related to ordinary window glass. The hard coat film may be made rough and may have a function of scattering transmitted light. An adhesive layer 32 and a separator are sequentially provided on the back surface side of the daylighting sheet 30, and the daylighting sheet 30 is attached to the window glass 31 by the adhesive layer 32 which peels off and exposes the separator.

  The pattern 11 of the light control part of the first door 2 and the pattern 11 of the light control part of the second door 3 in FIGS. 1 to 16 show the pattern of the light control part of the first door 2 when the window is opened. The light control units are not formed on the doors 2 and 3 so that the light control unit formations 11 and the light control unit formations 11 that are the patterns of the light control units of the second door 3 do not all overlap. The sliding window provided with the part 12 is illustrated.

  In this embodiment, the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 achieve a state in which at least a part does not overlap when the window is opened. When the window is opened, the formation portion 11 of the light control portion which is the pattern of the light control portion of the first door 2 and the formation portion 11 of the light control portion which is the pattern of the light control portion of the second door 3 are all The doors 2 and 3 are provided with the non-formation portion 12 of the light control portion so as not to overlap. Moreover, when three or more doors exist in a window, at least any two doors should just satisfy | fill the said relationship.

  When realizing the non-formation part 12 of the light control part, when forming the light control part pattern (formation part of the light control part) 11 by sticking the daylighting sheet 30 as in this example, It can be easily formed by providing a site to which the daylighting sheet 30 is not attached.

  If the difference in thickness between the non-formation part 12 of the light control part and the formation part 11 of the light control part is concerned or the difference in level is concerned, the light corresponds to the non-formation part 12 of the light control part of the daylighting sheet 30 The control function may not be generated. For example, the non-formation portion 12 of the light control portion may be provided by providing a portion where the concave groove 35 is not formed. Alternatively, instead of the filler 38, the non-formation portion 12 of the light control portion may be formed by using a transparent resin material having substantially the same refractive index as the resin forming the lens layer. Alternatively, a sheet which does not deflect light having substantially the same thickness as the daylighting sheet may be attached to the non-formation part 12 of the light control part.

  By this configuration, as shown in FIG. 1, FIG. 3, FIG. 5, FIG. 7, FIG. 9, FIG. In a state in which the first door 2 and the second door 3 are installed side by side, light incident on the forming portion 11 of the light control unit from the outdoor side is deflected upward and emitted to illuminate the ceiling, The light that has entered the non-formed portion 12 of the light control unit from the outdoor side can make the indoor space brighter by illuminating the floor by going approximately straight without deflection.

  In addition, as shown in FIGS. 2, 4, 6, 8, 10, 12, 14, and 16, a state in which the openable window 1 is open, that is, the first door 2 and the first door 2 In the state in which the second door 3 is installed in an overlapping manner, the light entering the forming portion 11 of the light control portion of the first door 2 from the outdoor side is the non-forming portion of the light control portion of the second door 3 In the portion overlapping 12, the indoor space can be brightened by deflecting upward and emitting light to illuminate the ceiling without being affected by the formation portion 11 of the light control portion of the second door 3. Further, the light incident on the non-forming part 12 of the light control part of the first door 2 from the outdoor side is overlapped with the forming part 11 of the light control part of the second door 3 in the first door 2. The indoor space can be brightened by deflecting the light upward and emitting it without being affected by the formation portion 11 of the light control portion and illuminating the ceiling.

  In the present embodiment, the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 do not overlap at least in part when the window is opened. When 1 is opened, that is, when the door 2 and the second door 3 overlap first (Fig. 2, Fig. 4, Fig. 6, Fig. 8, Fig. 10, Fig. 12, Fig. 14, Fig. 16) This means that non-overlapping portions of the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 exist.

  1 and 2 explain the first embodiment of the opening / closing window in which the pattern 11 of the light control portion is formed on the upper left of the diagonal of the first door 2 and to the lower right of the diagonal of the second door 3 Is a drawing.

  FIG. 1 shows a state in which the first door 2 and the second door 3 are installed side by side when the window is closed. Under the present circumstances, the light which entered the formation part 11 of the light control part of the door is deflected in the ceiling direction and emitted, and the light which entered the non-formation part 12 of the light control part of the door is not deflected but in the floor direction Emit and illuminate the room.

  FIG. 2 shows the pattern 11 of the light control section of the first door 2 and the light of the second door 3 when the openable window 1 is opened, that is, when the door 2 and the second door 3 overlap first. There is no overlapping portion of the pattern 11 of the control portion, and there is also no overlapping portion of the non-formation portion 12 of the light control portion of the first door 2 and the non-formation portion 12 of the light control portion of the second door 3 A pattern of the light control unit (formation unit of the light control unit) 11 and a non-formation unit 12 of the light control unit are provided.

  Therefore, even when the openable window 1 is opened, the non-forming portion 12 of the light control unit of the door 2 and the second door 3 does not interfere first, and the amount of light emitted toward the ceiling is not reduced. Also, in the open area where there is no door, the incident light goes straight and illuminates the floor. That is, even when the first door 2 and the second door 3 overlap when the window is opened, it is possible to provide the openable window 1 having a high light collecting effect by the light control member.

  3 and 4 show the first modified example of FIGS. 1 and 2, and the formation portion 11 of the light control portion of the first door 2 is shrunk slightly to the left from the form of FIGS. On the other hand, the formation portion 11 of the light control portion of the second door 3 is in the form of being shrunk to the right from the form in FIGS. 1 and 2.

  As shown in FIG. 4, when the openable window 1 is opened, that is, when the door 2 and the second door 3 overlap first, the pattern 11 of the light control portion of the first door 2 and the second door 3 There is no overlapping portion of the pattern 11 of the light control portion, and there is a overlapping portion of the non-formation portion 12 of the light control portion of the first door 2 and the non-formation portion 12 of the light control portion of the second door 3 The light control unit pattern (formation unit of the light control unit) 11 and the non-formation unit 12 of the light control unit are provided.

  As described above, even if the light control unit pattern (formation unit of the light control unit) 11 is provided, the light control units of the door 2 and the second door 3 are not firstly operated even when the openable window 1 is opened. The forming portions 12 do not interfere to reduce the amount of light emitted toward the ceiling. Also, in the portion where the door is not open and the non-formation portion 12 of the light control portion of the first door 2 and the non-formation portion 12 of the light control portion of the second door 3 overlap, incident light Go straight and light the floor. That is, even when the first door and the second door overlap when the window is opened, it is possible to provide the open / close window 1 having a high light collecting effect by the light control member.

  5 and 6 show the second modification of FIGS. 1 and 2, and the formation portion 11 of the light control portion of the first door 2 extends slightly to the right from the form of FIGS. On the other hand, the formation portion 11 of the light control portion of the second door 3 is spread to the left side from the form of FIGS. 1 and 2.

  When the openable window 1 is opened as shown in FIG. 6, that is, when the door 2 and the second door 3 overlap first, the pattern 11 of the light control portion of the first door 2 and the second door 3 Even if there is an overlapping portion of the pattern 11 of the light control portion, a portion where at least a part of the pattern 11 of the light control portion of the first door 2 and the pattern 11 of the light control portion of the second door 3 do not overlap It is an existing form.

  Light incident from the outside on the non-overlapping portion of the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 is mutually interfered with the pattern 11 of the light control unit Rather, it can be deflected upward with high efficiency to illuminate the ceiling. Therefore, compared with the case where the pattern 11 of the light control part of the conventional first door 2 and the pattern 11 of the light control part of the second door 3 overlap on the entire surface, the indoor space can be sufficiently brightened be able to. That is, even when the first door 2 and the second door 3 overlap when the window is opened, it is possible to provide the open / close window 1 with a high light collection effect by the light control member.

  Thus, the area of the overlapping portion of the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 and the non-forming portion 12 of the light control unit of the first door 2 The area of the overlapping portion of the non-formation part 12 of the light control part of the second door 3 and the pattern 11 of the light control part of the first door 2 and the pattern 11 of the light control part of the second door 3 do not overlap The ratio of the area of the part is the light quantity illuminating the floor and the light quantity illuminating the ceiling when the openable window 1 is closed, the light quantity illuminating the floor and the light quantity illuminating the ceiling when the openable window 1 is opened, and the distribution of incident light The design should be decided as necessary after considering the design, etc.

  By configuring as described above, when the window is opened, that is, even if the first door 2 and the second door 3 are overlapped, the opening / closing window with high light collection effect by the light deflection portion is realized it can.

  In FIG. 9 and FIG. 10, when the first door 2 and the second door 3 are divided into four or more vertically and horizontally divided into four or more windows, the first door 2 and the second door 3 are two pieces. A third type of open / close window configured to have non-overlapping portions of the pattern 11 of the light control section of the first door 2 and the pattern 11 of the light control section of the second door 3 even in the overlapping state To illustrate.

  11 and 12, when the window is opened with the first door 2 and the second door 3 vertically divided into three or more (four in the figure), that is, the first door 2 and the second door Even if two sheets of the second door 3 overlap, it is configured to have a non-overlapping portion of the pattern 11 of the light control section of the first door 2 and the pattern 11 of the light control section of the second door 3 The opening-and-closing window 1 of a 4th form is illustrated.

  Thus, in the middle of the opening and closing of the opening / closing window 1, the area of the overlapping portion of the pattern 11 of the light control unit of the first door 2 and the pattern 11 of the light control unit of the second door 3 changes. Configuration is also possible.

  With such a pattern configuration, even when the window is completely opened, that is, even when the first door 2 and the second door 3 completely overlap, the light deflection effect by the light deflection unit is A high opening and closing window can be realized, and the amount of light emitted toward the ceiling and the floor can be adjusted with the degree of opening and closing during opening and closing of the opening and closing window 1.
