Description

  The present invention relates to a daylight door that is used for a hinged door, a sliding door, or the like used in a building, and is provided with a daylighting unit at a predetermined position of the door.

  Conventionally, in the daylighting type sliding doors and sliding doors used in buildings, as shown in FIG. 7, an opening K is provided in the daylighting door 11, and a core S is attached to the periphery of the opening, as shown in FIG. The frame G in the vertical direction and the horizontal direction is attached to the core material S at the periphery of the opening of the daylighting door 11 from both the front and back surfaces of the daylighting door 11, and the frame G transmits light from both sides of the front and back surface of the daylighting door 11. A daylighting door 11 having a structure attached so as to sandwich the sex member Q has been used.

  In the daylighting door 11 having this structure, the work for attaching the frame G to the core S around the opening is complicated and inferior in workability, and the frame G protrudes from the surface of the daylighting door 11. Although it can be used, when it becomes a sliding door, it is difficult to use the frame G easily during the opening / closing operation.

  Therefore, the interior panel with the daylighting window, which is made for the purpose of easily forming the daylighting window in which the translucent member is flush with the surface material, has a planar shape in the plane shape of the opening formed in the surface material. A translucent member having an equalized main body and a flange formed around the main body is fixed to the back surface of the surface material, and the main body of the translucent member is fitted into the opening of the surface material so that the surface material and the surface face each other. Become one. Thus, there is a description of an interior panel with a daylighting window having a configuration in which two surface materials whose light-transmitting members are flush with each other are fixed. (For example, refer to Patent Document 1).

JP-A-2005-232879. (Page 1-5, Figure 1-4).

  By the way, in the above-mentioned prior art, in the frame type, as described above, the attachment work when attaching the frame G to the core material S provided at the periphery of the opening is extremely complicated, and therefore the workability is inferior. There was a problem. In addition, since the frame protrudes from the surface of the daylighting door, there is no problem in use when using it as a swing door, and there is no particular problem. The picture frames of the sliding doors were easily touched and difficult to use. Further, even in the sliding door, the protruding portion of the frame G of the sliding door and the wall surface are easily in contact during the opening / closing operation and are difficult to use. In addition, the translucent member Q attached so as to be sandwiched by the frame G is seen through the back base material of the frame G at the sandwiched portion of the periphery of the frame G. Since the defects of the base material such as discoloration can be seen from the outside, there is also a problem that the appearance is unsightly. In addition, even in the case of a groundwork other than wood, there is a problem that it is difficult to see the appearance due to the appearance of different types of defects than wood.

  Moreover, in the interior panel with a daylighting window described in JP-A-2005-232879, since the main body of the translucent member is fitted into the opening formed in the surface material, the shape of the opening in the surface material The size and the shape and size of the main body of the translucent member are required to be finished with extremely high accuracy. If the main body of the translucent member is slightly large, it cannot be fitted into the opening, and conversely, if it is slightly small, after fitting, a gap will be formed at that location, which is very unsightly. Further, the gap is not only limited in size in the width direction, but the depth of the gap is a large dimension corresponding to the thickness of the main body of the translucent member, and is a conspicuous gap in dimension. In order to eliminate this gap, not only the shape and dimensional accuracy of the translucent member body but also the shape and dimensional accuracy of the opening of the surface material can be finished with extremely high accuracy, which is extremely difficult in terms of processing technology. It is a thing.

  The present invention has been made in view of the above-described circumstances.

The internal structure of the daylighting door 1 according to the present invention is such that, in this example, two longitudinal and two outer peripheral cores S1 are structured in a rectangular shape, and an inner peripheral core S2 is longitudinally arranged therein. Two and two in the horizontal direction are provided. The decorative board and the translucent member 5 are stuck on both surfaces of the front and back surfaces of the base core material 6 thus formed to form the daylighting door 1 of the present invention. A hollow portion U is formed between the core material S and the core material S, and a door having a so-called flash structure is illustrated.

  In this example, the decorative board is composed of a vertical decorative sheet 2a for forming the vertical hook 2 and a horizontal decorative sheet 3a for forming the horizontal stick 3, and the predetermined positions on both the front and rear surfaces of the core member 6 are as follows. It is affixed to. Moreover, in this example, the translucent member 5 is stuck from the both surfaces of the front and back surfaces of the core assembly material 6 at the position of the opening K in the central portion surrounded by the four inner peripheral core materials S2, The lighting door 1 of the present invention is formed with the decorative plate and the translucent member 5 being substantially flush with each other.

  The daylighting door 1 shown in this example is provided with a vertically long translucent member 5 in the longitudinal direction at one central portion of the door as shown in FIG. In addition to this, of course, a plurality of vertically long translucent members 5 may be provided in the vertical direction. Further, it may be horizontally long instead of vertically long, or may be slanted. By appropriately setting the arrangement and the number of inner peripheral core materials S2 according to the design of the daylighting portion of the daylighting door 1, it is possible to cope with various daylighting unit designs.

  The vertical wall decorative board 2a and the horizontal wall decorative board 3a used for the daylighting door 1 of the present invention have a thickness on the surface of a plywood or medium specific gravity fiber board having a thickness of about 2.5 to 9.0 mm, for example. Stick a veneer or veneer made of natural wood such as oak, zelkova, cherry, hippopotamus, teak, walnut, mahogany, pine, persimmon, rosewood, ebony, etc. Suitable examples include those that are surface-coated with a transparent or colored transparent synthetic resin coating made of urethane resin, acrylic resin, polyester resin, or the like. However, it is not limited to the veneer or veneer of natural name wood made of these tree species. The surface coating is not limited to these synthetic resin paints.

  Of course, a decorative sheet such as an olefin resin decorative sheet, a vinyl chloride resin decorative sheet, or a decorative paper may be used instead of the veneer or veneer made of natural wood. For example, the surface of an olefin resin sheet, a vinyl chloride resin sheet, a thin paper, or the like that has been printed with a wood grain pattern or the like can be exemplified as a suitable one.

  In addition to the above-mentioned materials, in addition to decorative plates that have been surface-coated by attaching the above-mentioned various decorative sheets, natural veneer plates, veneers, etc. to inorganic substrates such as calcium plates and pulp cement plates, galvanized steel sheets A metal decorative plate such as a coated steel plate or the like can be exemplified as a suitable one.

  The translucent member 5 includes an acrylic resin molded body, a polycarbonate resin molded body, a laminated glass body bonded with a transparent or translucent plate glass, a tempered glass body, a netted glass body, a template glass body, and the like. Other transparent or translucent synthetic resin moldings are preferably used. In addition to the colorless one, it may be colored in consideration of design. Of course, it is not limited to these.

  Moreover, the material of the core material S used for the said core frame material 6 can illustrate softwood materials, such as a rice pine and a rice bran, for example other than southern materials, such as Lawan, Merapi, Kapole, Johncon, and Meranti. . Of course, it is not limited to these.

  The position where the translucent member 5 of the present invention, the downspout decorative board 2a, and the downspout decorative board 3a are attached is preferably performed at the inner peripheral core S2. When the inner peripheral core material S2 is located immediately below the pasted portion, it is suitable for the strength durability of the daylighting door 1 itself.

  The decorative door and the translucent member 5 are attached to the inner peripheral core material S2 and the outer peripheral core material S1 with an adhesive H to form the daylighting door 1. The adhesive H used when the decorative plate and the translucent member 5 are attached to the inner peripheral core material S2 and the outer peripheral core material S1 is a urethane resin in the case of bonding the wooden decorative plate and the core material S. Further, woodworking adhesives such as acrylic resins and vinyl acetate resins are suitable for bonding workability and bonding strength. In the case of an inorganic decorative board, a metallic decorative board, etc., an adhesive suitable for each may be selected as appropriate.

  In FIG. 4, the expanded sectional view in the part by which the translucent member 5 and decorative board of the lighting door 1 of this invention are stuck is shown. In the pasted portion, the edge on the opening K side (the side on which the translucent member 5 is located) of the vertical decorative plate 2a and the horizontal decorative plate 3a, that is, the cross-section in the thickness direction of the decorative plate The edge on the opening side is inclined in such a direction that the area of the opening surrounded on the front side of the decorative plates 2a and 3a is smaller than the opening surrounded on the back side of the decorative plates 2a and 3a. A taper is formed. The same applies to the back surface side of the panel body 4 at the opposite position in the thickness direction. Then, when viewed from the cross-sectional view of FIG. 4, the panel body 4 has a vertically symmetrical shape when viewed from the center line (not shown) of the thickness of the panel body 4. The translucent member 5 has a trapezoidal shape corresponding to the cross-sectional shape of the opening K. Also in this translucent member 5, it is made into the shape of line symmetry up and down seeing from the center line (not shown) of the thickness of the panel main body 4 in a cross sectional view.

  More specifically, in this example, the edge of the translucent member 5 is formed with the taper T formed on the edges of the vertical wall decorative plate 2a and the horizontal wall decorative plate 3a and the corresponding inclination angle and size. The adhesive H is also applied to the taper T formed on the surface. Furthermore, the adhesive H for attaching the translucent member 5 to at least one of the front surface (the back and front two surfaces) of the inner peripheral core material S2 and the peripheral edge of the rear surface side 5b of the translucent member 5 is provided. It has been applied. Thus, the decorative plate, the location where the translucent member 5 is in contact with the surface of the inner peripheral core material S2 (the back surface of the core material S2 and the two surfaces on the front), and the taper T of the translucent member 5 and the makeup Since the adhesive H is provided at both locations where the taper T contacts the plate, the daylighting door 1 after completion of the bonding is excellent in strength durability.

  Further, due to the taper T, the contact portion at the edge between the decorative plate and the translucent member 5 is inclined, and thus the contact area is increased. This leads to an increase in the bonding area, and the connection between the decorative board and the translucent member 5 becomes even stronger.

  In addition, the processing accuracy of the decorative plate and the translucent member 5 is slightly low, and even if a gap occurs between the decorative plate and the translucent member 5, the edges of the decorative plate and the translucent member 5 are Because of the oblique contact due to the taper T, when viewed from above, the depth of the gap naturally becomes shallow, and therefore the gap becomes less conspicuous.

  Further, the material, color tone, and design of the light transmitting member 5 on the front surface side and the light transmitting member 5 on the back surface side of the panel body 4 may be consciously changed. Thus, it can be made more excellent in appearance by changing the design and color tone on the front and back surfaces of the daylighting door 1.

  In FIG. 5, the coloring to the surface part of the back surface side 5b peripheral part and inner peripheral part core material S2 of the translucent member 5 of this invention is demonstrated. Of the core material S of the core material 6 constituting the panel body 4, an inner peripheral core material S <b> 2 is provided on the periphery of the opening K. The periphery of the translucent member 5 on the back surface 5b side is configured to be attached and fixed to the surface of the inner periphery core material S2 at the periphery of the opening K. In addition, an adhesive H (see FIG. 4) is used on the surface of the inner peripheral core material S2 (in this example, a total of four in the longitudinal direction and two in the lateral direction), and thus the translucency of the present invention. The member 5 is attached and fixed.

  Color coating is performed using the color coating P on both or either of the surface of the inner periphery core material S2 at the periphery of the opening K of the panel body 4 having such a configuration and the rear surface 5b side periphery of the translucent member 5. It has been subjected. As described above, the inner peripheral core material is coated with the colored paint P at the location where the translucent member 5 is attached to the inner peripheral core material S2 at the periphery of the opening K. Defects such as nodes, discoloration, and decay of the wood material on the surface of S2 are effectively concealed, and the visual appearance is excellent in aesthetics. The colored paint P can be exemplified by a suitable synthetic resin paint such as a urethane resin, a polyester resin, an acrylic resin, and an amino alkyd resin. A colored paint having low transparency or an opaque colored paint is suitable.

In FIG. 6, an example of the manufacturing method of the lighting door 1 of this invention is shown. When manufacturing the lighting door 1 of this invention, it carries out in the following procedures.
1. In accordance with the finished design of the daylighting portion of the daylighting door 1, the core assembly 6 that is the base is produced by combining the outer periphery core material S1 and the inner periphery core material S2. At this time, if necessary, the inner peripheral core material S2 surface (the back and front two surfaces) is colored and coated with the colored paint P.
2. The vertical wall decorative plate 2a, the horizontal wall decorative plate 3a, and the translucent member 5 are preliminarily bonded with an adhesive H to the ends of each member (the taper T of the decorative plate edge and the end of the translucent member 5). The taper T) is adhered to produce the surface structure material 7. At this time, if necessary, the outer surface is reinforced with a reinforcing tape M. If necessary, the colored paint P is also applied to the peripheral portion of the translucent member 5 on the back surface 5b side in advance.
3. The surface structure material 7 on the back surface side of the panel body 4 is produced in the same manner.
4). Adhesive H is applied to both sides of the core assembly 6.
