Description

[Technical Field]

[0001] The present disclosure relates to entry doors. [Background technology]

[0002] Conventionally, there has been known a door in which multiple decorative elements formed into long pieces by extruding aluminum or the like on the surface of the door body are fixed to the door body by multiple decorative element fixing parts that penetrate the decorative elements (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-3414 Summary of the Invention [Problem to be solved by the invention]

[0004] In the door described in Patent Document 1, the decorative element is fixed to the door surface by multiple decorative element fixing parts, making the process of attaching the decorative element complicated. Moreover, the decorative element fixing parts protrude from the door surface and are therefore easily noticeable. Furthermore, components such as aluminum extrusions are given a decorative effect by attaching a wrapping sheet to the surface, which makes the texture of the metal easily visible on the surface. Therefore, conventional doors have room for improvement in terms of improving their design.

[0005] Therefore, the inventor has found a problem to be solved by providing an entrance door that can further improve the design. [Means for solving the problem]

[0006] The entrance door of the present disclosure comprises a door body that is openably and closably placed inside a door frame provided in an opening in a building frame, and a tile that is adhered to at least one of the exterior and interior sides of the door body via an adhesive layer, and the tile is arranged so as to extend from the top end or near the top end of the door body to the bottom end.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. An entrance door 1 shown in Figures 1 to 3 has a door body 3 inside a metal door frame 2 provided in a vertically long rectangular opening 101 in a building skeleton 100. The door body 3 is a hinged door whose door tip can be opened and closed in the indoor and outdoor directions, centered on the hanging side.

[0009] The door frame 2 is formed from a metal extrusion and attached along the inner periphery of the opening 101. More specifically, the door frame 2 is framed in a rectangular shape by an upper door frame 21 extending laterally along the upper inner periphery of the opening 101, a lower door frame 22 extending laterally along the lower inner periphery of the opening 101, and a leading-side vertical door frame 23 and a hanging-side vertical door frame 24 extending vertically along the left and right inner periphery of the opening 101. The upper door frame 21, leading-side vertical door frame 23, and hanging-side vertical door frame 24 are each formed into a hollow rectangular shape.

[0010] Ceramic exterior tiles 200 are attached with adhesive or the like to the exterior surface around the opening 101 of the building skeleton 100. The exterior tiles 200 are arranged to cover the exterior surfaces 21a, 23a, 24a of the upper door frame 21, the door-end vertical door frame 23, and the hanging-end vertical door frame 24, respectively, and are located close to the entrance door 1. Figure 1 shows the entrance door 1 as seen from the outside. In each figure, X1 indicates the outside side of the entrance door 1, and X2 indicates the inside side of the entrance door 1.

[0011] The entrance door 1 has a door body 3 that is housed inside a door frame 2, and tiles 4 that serve as decorative materials that are attached to the exterior side of the door body 3. The door body 3 is attached to a vertical door frame 24 on the hanging side by hinges 35 so that it can be opened and closed.

[0012] As shown in Figures 2 and 3, the door body 3 has a core material 31 that is framed in a rectangular shape around all four sides of the door body 3, a metal exterior panel portion 32 that is provided on the exterior side of the core material 31, a metal interior panel portion 33 that is provided on the interior side of the core material 31, and a heat insulating material 34 that is provided in the space surrounded by the core material 31, the exterior panel portion 32, and the interior panel portion 33.

[0013] The core material 31 of this embodiment is composed of a metal core material 311 and a resin core material 312 provided so as to cover the outer periphery of the metal core material 311 .

[0014] 4 to 7, the metal core member 311 is configured to include an upper metal core member 311a extending laterally from the upper end of the door body 3, a lower metal core member 311b extending laterally from the lower end of the door body 3, a door-edge metal core member 311c extending vertically from the door-edge side end of the door body 3, and a hanging-edge metal core member 311d extending vertically from the hanging-edge side end of the door body 3. These metal core members 311a, 311b, 311c, and 311d are all formed in a U-shape and are framed in a rectangular shape so that the outer periphery forms a flat visible surface.

[0015] As shown in Figures 4, 5, and 7, the resin core 312 includes an upper resin core 312a extending laterally along the upper end of the door body 3, a lower resin core 312b extending laterally along the lower end of the door body 3, and a hanging base resin core 312d extending vertically along the hanging base end of the door body 3. The upper resin core 312a, lower resin core 312b, and hanging base resin core 312d are all U-shaped and closely cover the outer surfaces of the upper metal core 311a, lower metal core 311b, and hanging base metal core 311d, respectively, and are fixed to the metal cores 311a, 311b, and 311d with mounting screws SC1, SC2, and SC4, respectively. As shown in Figure 3, the hinge 35 is attached across the hanging base resin core 312d of the door body 3 and the hanging base vertical door frame 24 of the door frame 2.

[0016] Such a U-shaped resin core material is not provided on the door end metal core material 311c of the door body 3. Instead, as shown in Figures 3 and 6, resin cover materials 313a and 313b are individually attached to the exterior and interior sides of the door end metal core material 311c of the door body 3, respectively.

[0017] In this way, the front door 1 has not only the insulating and moisture-proofing properties provided by the insulating material 34, but also the insulating and moisture-proofing properties provided by the resin core material 312 and resin cover materials 313a, 313b provided on the outer surface side of the metal core material 311 around all four sides of the door body 3, so it has even better insulating and moisture-proofing properties.

[0018] As shown in FIGS. 2 to 7 , the tile 4 is sized to cover the entire surface of the exterior panel 32 that constitutes the exterior side of the door body 3, and is adhered to the surface of the exterior panel 32 by an adhesive layer 5. Specifically, the tile 4 of this embodiment has a height from the upper end to the lower end of the exterior panel 32 of the door body 3 and a width from the edge-side end of the exterior panel 32 of the door body 3 to the hinge-side end, and is adhered via the adhesive layer 5. The adhesive layer 5 may be formed of an adhesive applied to at least one of the back surface of the tile 4 and the surface of the exterior panel 32, or may be formed of a double-sided adhesive tape. The tile 4 of this embodiment is formed of a single ceramic tile plate sized to substantially cover the entire surface of the exterior side of the door body 3 from the upper end to the lower end and from the edge-side end to the hinge-side end.

[0019] The tiles 4 are fixed by being adhered to the door body 3 with the adhesive layer 5. Therefore, unlike conventional methods, there is no need to use fixing parts that penetrate the tiles 4 to fix the tiles 4. Furthermore, the surface texture of the entrance door 1 is expressed by the material of the tiles 4 itself, so the entrance door 1 has a high level of design due to the natural texture of the tiles 4. Therefore, the configuration of this entrance door 1 can further improve the design.

[0020] The tiles 4 of the entrance door 1 may be made of the same material as the exterior tiles 200 provided around the opening 101 of the building skeleton 100. This makes it easy to unify the design of the entrance door 1 and the building skeleton 100, further improving the design of the entrance door 1.

[0021] 4 to 7, edge members are provided on the four sides of the tile 4, respectively covering edge surfaces 41a, 42a, 43a, and 44a of the tile 4. More specifically, an upper edge member 6, a lower edge member 7, a door-edge edge member 8, and a hanging edge member 9 are provided on the four sides of the tile 4. This protects the edge surfaces 41a, 42a, 43a, and 44a of the tile 4, thereby suppressing damage and improving the durability of the tile 4.

[0022] 2 and 4, the upper edge member 6 is formed of a thin, L-shaped metal profile member consisting of a surface abutment plate portion 61 and an attachment plate portion 62. The upper edge member 6 extends over almost the entire width of the door body 3.

[0023] The surface contact plate portion 61 contacts the upper surface of the tile 4, specifically, the surface 41b of the upper edge of the tile 4. The mounting plate portion 62 is integrally provided on the upper end of the surface contact plate portion 61, covers the end face 41a, and extends toward the inside of the room.

[0024] The mounting plate portion 62 is fixed to the surface of the upper resin core material 312a, which is the upper visible surface of the door main body 3, with mounting screws SC1. In this way, the upper edge member 6 is fixed to the door main body 3.

[0025] The upper edge member 6 is formed in an L shape by the surface abutment plate portion 61 and the mounting plate portion 62, and therefore in addition to the function of covering and protecting the edge surface 41a, it also has the function of engaging and fixing the surface 41b of the upper edge of the tile 4 by the surface abutment plate portion 61. Therefore, the upper edge member 6 prevents damage to the edge surface 41a of the tile 4, and fixes the upper side of the tile 4 to the door body 3, preventing the upper side of the tile 4 from peeling off from the door body 3.

[0026] 2 and 5, the lower edge member 7 is formed of a thin, L-shaped metal profile member consisting of a surface abutment plate portion 71 and an attachment plate portion 72. The lower edge member 7 extends over almost the entire length of the door body 3 in the width direction.

[0027] The surface abutment plate portion 71 abuts against the lower surface of the tile 4, specifically, the surface 42b of the lower edge portion of the tile 4.

[0028] The mounting plate portion 72 is integrally provided at the lower end of the surface abutment plate portion 71, covers the end face 42a, and extends in the front direction of the door body 3 toward the interior side. The mounting plate portion 72 is fixed to the surface of the lower resin core material 312b, which is the front face of the lower side of the door body 3, with mounting screws SC2. In this way, the lower edge member 7 is fixed to the door body 3.

[0029] The lower edge member 7 is formed in an L shape by the surface abutment plate portion 71 and the mounting plate portion 72, and therefore in addition to the function of covering and protecting the edge surface 42a, it also has the function of engaging and fixing the surface 42b of the lower edge of the tile 4 by the surface abutment plate portion 71. Therefore, like the upper edge member 6, the lower edge member 7 prevents damage to the edge surface 42a of the tile 4 and fixes the underside of the tile 4 to the door body 3, preventing the underside of the tile 4 from peeling off from the door body 3.

[0030] 3 and 6, the door-leading edge member 8 is made of a thin metal plate-shaped member consisting of a surface abutment plate portion 81, an extension plate portion 82, a leg plate portion 83, and an attachment plate portion 84. The door-leading edge member 8 extends over almost the entire length of the door body 3 in the height direction.

[0031] The surface abutment plate portion 81 abuts against the leading surface of the tile 4, specifically, the surface 43b of the leading edge of the tile 4.

[0032] The extension plate portion 82 is integrally formed with the surface abutment plate portion 81 and extends flush with the surface abutment plate portion 81 toward the door-end vertical door frame 23 so as to overlap with the door-end vertical door frame 23.

[0033] As shown in FIG. 3 , the leading-side vertical door frame 23 has a step 23b recessed toward the interior at a corner of the exterior surface 23a facing the door body 3. The extension plate 82 extends from the surface abutment plate 81 toward the step 23b of the leading-side vertical door frame 23 and is housed within this step 23b. As a result, the extension plate 82 of the leading-side edge member 8 is positioned overlapping the leading-side vertical door frame 23. A sealing piece 821 protruding toward the interior is provided at the tip of the extension plate 82. The sealing piece 821 abuts against the step 23b from the exterior side, thereby sealing the gap between the entrance door 1 and the leading-side vertical door frame 23.

[0034] The leg plate portion 83 is integrally formed on the back surface of the front surface abutment plate portion 81, covers the end surface 43a, and extends toward the inside of the room. The tip of the leg plate portion 83 abuts against the surface of the resin cover material 312c1 on the outside of the room.

[0035] The mounting plate portion 84 extends from the extension plate portion 82 toward the interior side of the door body 3 in the front direction. The mounting plate portion 84 is fixed to the surface of the door-leading metal core material 311c, which is the front surface on the door leading side of the door body 3, with a mounting screw SC3. In this way, the door-leading edge member 8 is fixed to the door body 3.

[0036] The leading edge member 8 is formed in a T-shape by the surface abutment plate 81, the extension plate 82, and the mounting plate 84. In addition to covering and protecting the edge 43a, the leading edge member 8 also functions to engage and secure the surface 43b of the leading edge of the tile 4 with the surface abutment plate 81. Therefore, like the upper edge member 6 and the lower edge member 7, the leading edge member 8 prevents damage to the edge 43a of the tile 4 and secures the leading edge of the tile 4 to the door body 3, preventing the leading edge of the tile 4 from peeling off from the door body 3. Furthermore, because the surface abutment plate 81 and the extension plate 82 are flush with each other, the leading edge member 8 does not protrude significantly when the leading edge of the entrance door 1 is viewed from the outside. This ensures that the design of the entrance door 1 is not compromised.

[0037] 3 and 7, the hanging edge member 9 is composed of a thin, U-shaped metal profile that sandwiches the hanging side of the tile 4 from the front and back, covering the end surface 44a. The hanging edge member 9 extends over almost the entire height of the door body 3. Specifically, the hanging edge member 9 comprises a front contact plate portion 91 that contacts the front surface 44b of the hanging edge of the tile 4, a back contact plate portion 92 that contacts the back surface 44c of the hanging edge of the tile 4, and a connecting plate portion 93 that covers the end surface 44a and connects the front contact plate portion 91 and the back contact plate portion 92. The hanging edge member 9 is fixed to the end surface 44a by adhesive on the inner surface of the connecting plate portion 93, for example, with double-sided adhesive tape 94.

[0038] The back surface abutment plate portion 92 clamps the end of the tile 4 on the hanging side between itself and the front surface abutment plate portion 91, thereby more reliably protecting the edge 44a of the tile 4. The back surface abutment plate portion 92 has the same thickness as the adhesive layer 5. Therefore, there is no risk that the back surface abutment plate portion 92 will affect the fixation of the tile 4 by the adhesive layer 5. The back surface of the tile 4 on the hanging side is supported by the back surface abutment plate portion 92, so the fixed state of the hanging side of the tile 4 is also stable.

[0039] In this way, the edges 41a, 42a, 43a, and 44a of the tiles 4, which are generally prone to damage, are protected by the upper edge member 6, lower edge member 7, leading edge member 8, and hanging edge member 9, respectively, thereby maintaining the tiles 4 from damage over a long period of time and improving their durability. Because the upper edge member 6, lower edge member 7, leading edge member 8, and hanging edge member 9 are thin plates, they do not protrude significantly from the surface of the entrance door 1, thereby not compromising the design of the entrance door 1. Furthermore, the upper edge member 6, lower edge member 7, and leading edge member 8 also function to lock and secure the tiles 4 to the door body 3, preventing the tiles 4 from peeling off. Because the tiles 4 are bonded to the door body 3 by the adhesive layer 5, the surface abutment plate portions 61, 71, 81, and 91 of the edge members 6, 7, 8, and 9 can be formed as narrow as possible. Therefore, the influence of the edge members 6, 7, 8, and 9 on the design of the entrance door 1 can be minimized.

[0040] The hanging edge member is not limited to being provided so as to sandwich the hanging side of the tile 4 from both sides. For example, as shown in Fig. 8, the hanging edge member 90 may be attached to the exterior surface 310 of the core material 31 on the hanging side with double-sided adhesive tape 97.

[0041] As shown in Figure 8, the hanging edge member 90 has an edge member main body 95 made of a hollow rectangular material. The exterior surface of the edge member main body 95 extends toward the surface 44b of the hanging edge portion of the tile 4. This forms a surface abutment plate portion 96 that abuts against the surface 44b of the hanging edge portion of the tile 4. Because the hanging edge member 90 does not sandwich the tile 4 from the front or back, the entire back surface of the tile 4 can be adhered with the adhesive layer 5. The hanging edge member 90 can be fixed to the hanging side of the door body 3 after the tile 4 is adhered to the door body 3, making installation of the hanging edge member 90 easy.

[0042] As shown in Figure 1, the door body 3 of the front door 1 has a handle 11 for opening and closing that extends vertically on the surface of the tile 4. As shown in Figures 9 and 10, cylinders 121, 121 of locks 12, 12 are respectively disposed at the upper and lower ends of the handle 11. The lock 12 is, for example, an electric lock.

[0043] Mounting holes 45, 45 for the cylinders 121, 121 are provided in the tile 4 in correspondence with the positions of the cylinders 121, 121. The mounting holes 45, 45 are through-holes with a diameter larger than the outer diameter of the cylinders 121, 121. The cylinders 121, 121 are mounted to the exterior panel portion 32, which is the exterior side surface of the door main body 3, through the mounting holes 45, 45. With this configuration, the cylinders 121, 121 are not affected by the thickness of the tile 4 when they are mounted to the door main body 3, so existing products can be used as is.

[0044] Cylinder covers 13, 13 that cover the cylinders 121, 121 are attached to the upper and lower ends of the handle 11, respectively. The cylinder covers 13, 13 entirely conceal the cylinders 121, 121 and the mounting holes 45, 45. As a result, not only the cylinders 121, 121 but also the mounting holes 45, 45 are not visible from outside the vehicle, and the design is not impaired.

[0045] 11 and 12 show a sliding entrance door 1A. In the entrance door 1A, parts with the same reference numerals as in the hinged entrance door 1 indicate parts with the same configuration. This entrance door 1A has a door body 3A that is housed inside a door frame 210 installed in an opening (not shown) in a building frame (not shown) so that it can be opened and closed by sliding laterally. As with the hinged entrance door 1, the sliding entrance door 1A may also have exterior tiles installed around the opening in the building frame.

[0046] The door frame 210 is formed by framing an upper door frame 211, a lower door frame 212, and vertical door frames 213, 214, and 215, each made of metal extrusions, into a rectangular shape. The vertical door frames 213 and 214 form the vertical door frames at the left and right ends of the door frame 210. The vertical door frame 215 forms the vertical door frame in the center of the door frame 210. The door frame 210 may not have the vertical door frame 214. The door body 3A is provided so as to be slidable along the extension direction of the upper door frame 211 and the lower door frame 212. A tile 4 and a handle 11 similar to those of the entrance door 1 are provided on the exterior surface of the door body 3A. The handle 11 is equipped with a lock 12 having a cylinder 121. The lock 12 of the entrance door 1A is, for example, a manual lock and an electric box lock that electrically opens and closes a thumb turn.

[0047] The upper door frame 211 is formed in a rectangular shape that opens downward so as to accommodate the upper end of the door main body 3A in a slidable manner. As shown in Fig. 12, a guide rail 211a that extends along the extension direction of the upper door frame 211 is provided inside the upper door frame 211.

[0048] 11 and 12, a guide roller 212a protruding from the upper surface is provided at approximately the center in the extension direction of the lower door frame 212. As shown in Fig. 11, the guide roller 212a is disposed on the upper surface of the lower door frame 212, near the vertical door frame 215, at a position corresponding to the lower part of the door trailing edge of the door main body 3A in the closed position.

[0049] As shown in Figures 14 to 17, the door body 3A has core materials 31a to 31d framed in a rectangular shape around the four periphery of the door body 3A, a metal exterior panel portion 32 provided on the outdoor side of the framed core materials 31a to 31d, a metal interior panel portion 33 provided on the indoor side of the framed core materials 31a to 31d, and a heat insulating material 34 provided in the space surrounded by the framed core materials 31a to 31d, the exterior panel portion 32 and the interior panel portion 33.

[0050] 12, the upper end of the door main body 3A is inserted into the inside of the upper door frame 211. A hoisting wheel (not shown) protruding upward from the upper end surface of the door main body 3A is placed on the guide rail 211a of the upper door frame 211 so as to be able to roll, and thus the door main body 3A is suspended so as to be able to slide along the guide rail 211a.

[0051] As shown in FIGS. 12 and 15, a guide groove frame 36 having an upwardly recessed shape is provided on the lower end surface of the door main body 3A. The guide groove frame 36 is made of a metal molding and is attached to the lower surface of the lower core material 31b of the door main body 3A with a plurality of mounting screws SC5. The guide groove frame 36 engages with a guide roller 212a protruding from the upper surface of the lower door frame 212, thereby smoothly guiding the movement of the lower end of the door main body 3A during sliding movement along the guide rail 211a. Although not shown, a guide roller is also provided on the lower part of the door edge side of the door main body 3A. This guide roller smoothly guides the movement of the door edge side of the door main body 3A during sliding movement.

[0052] As shown in FIGS. 11 to 17, the tile 4 in this entrance door 1A also has a size that covers substantially the entire exterior side of the door body 3A, and is adhered to the surface of the exterior panel 32 by an adhesive layer 5. Specifically, the tile 4 in this embodiment has a height extending from near the upper end to the lower end of the exterior panel 32 of the door body 3A, and a width extending from the leading end (right end in FIG. 13) to the trailing end (left end in FIG. 13) of the exterior panel 32 of the door body 3A. The tile 4 is not provided on the upper end 30 of the door body 3A that is inserted into the upper door frame 211. The tile 4 is adhered to the surface of the exterior panel 32 that faces the exterior between the upper door frame 211 and the lower door frame 212, except for the upper end 30 of the door body 3A.

[0053] Next, we will explain the edge members that cover and protect the four edges 41a, 42a, 43a, and 44a of the tiles 4 in the entrance door 1A. The edge members in the entrance door 1A are made up of a thin plate-shaped upper edge member 6A, lower edge member 7A, leading edge member 8A, and trailing edge member 9A. These edge members 6A, 7A, 8A, and 9A are all attached to the door body 3A after the tiles 4 have been adhered to the door body 3A.

[0054] 14, 18, and 19, the upper edge member 6A is made of a metal molding integrally having a surface plate portion 61A that covers the surface of the tile 4, an upper surface plate portion 62A that covers the edge surface 41a of the tile 4, and an abutment plate portion 63A that abuts against the exterior plate portion 32 of the upper end portion 30 of the door body 3A. The upper edge member 6A extends over almost the entire width of the door body 3A.

[0055] The front panel portion 61A covers the surface 41b of the upper end of the tile 4. The upper panel portion 62A is integrally formed with the upper end of the front panel portion 61A and covers the edge 41a. The abutment plate portion 63A is integrally formed with the interior end of the upper panel portion 62A and extends upward along the exterior facing surface (the upper end of the exterior panel portion 32) exposed at the upper end 30 of the door body 3A. The upper edge member 6A is adhered to the upper end of the exterior panel portion 32 by an adhesive layer (not shown) provided on the back surface of the abutment plate portion 63A. The adhesive layer can be an adhesive or double-sided adhesive tape. In this embodiment, the front panel portion 61A of the upper edge member 6A does not abut against the tile 4, but the front panel portion 61A may abut against the surface 41b of the upper end of the tile 4 to prevent the upper side of the tile 4 from peeling off from the door body 3A.

[0056] 15, 20, and 21, the lower edge member 7A is made of a metal molding integrally having a front plate portion 71A that covers the surface of the tile 4 and a lower plate portion 72A that covers the edge surface 42a of the tile 4. The lower edge member 7A is provided integrally with the guide groove frame 36, and extends over almost the entire width of the door body 3A.

[0057] The front panel portion 71A covers the surface 42b of the lower end of the tile 4. The lower panel portion 72A is integrally formed with the indoor end of the front panel portion 71A. The indoor end of the lower panel portion 72A is integrally formed with the outdoor end of the guide groove frame 36.

[0058] Because the lower edge member 7A is integral with the guide groove frame 36, by fixing the guide groove frame 36 to the lower core material 31b of the door body 3A, it is possible to simultaneously construct the lower edge member 7A that protects the lower edge surface 42a of the tile 4. Although the surface plate portion 71A of the lower edge member 7A in this embodiment does not abut against the tile 4, the surface plate portion 71A may abut against the surface 42b of the lower end of the tile 4 to prevent the lower side of the tile 4 from peeling off from the door body 3A.

[0059] 16, 18, and 20, the door-leading edge member 8A is made of a metal molding integrally having a front plate portion 81A that covers the surface of the tile 4, a side plate portion 82A that covers the edge surface 43a of the tile 4, a mounting plate portion 83A that is attached to the core material 31c of the door body 3A, and a back plate portion 84A that abuts against the back surface of the tile 4. The door-leading edge member 8A extends over almost the entire height of the door body 3.

[0060] The front panel 81A covers the front surface 43b of the leading edge of the tile 4. The side panel 82A is integral with the front panel 81A and extends along the leading edge 3a of the door body 3A, covering the edge 43a of the tile 4. The mounting panel 83A bends slightly inward from the interior edge of the side panel 82A and extends toward the interior. The back panel 84A is positioned to abut against the back surface 43c of the leading edge of the tile 4. The back panel 84A is integral with the exterior edge of a side panel 841, which extends parallel to the side panel 82A, on the inside of the side panel 82A. The interior edge of the side panel 841 is integral with the mounting panel 83A. The leading edge member 8A is fixed to the leading edge core 31c of the door body 3A with multiple mounting screws SC6 that penetrate the mounting panel 83A.

[0061] As shown in FIG. 16, the leading edge of the tile 4 protrudes slightly outward in the front view (to the left in FIG. 16) beyond the leading edge core 31c of the door body 3A. The back plate 84A sandwiches the leading edge of the tile 4, which protrudes outward in the front view, between the back plate 84A and the front plate 81A. This more reliably protects the edge 44a of the tile 4. Because the tile 4 protrudes outward in the front view, the leading edge edge member 8A can be easily attached so that the back plate 84A abuts the back surface 43c of the tile 4, even after the tile 4 is bonded to the door body 3A. Because the back plate 84A is thinner than the adhesive layer 5, there is no risk that the back plate 84A will affect the fixation of the tile 4 by the adhesive layer 5. Because the back surface 43c of the tile 4 on the leading edge side is supported by the back plate 84A, the fixation of the leading edge of the tile 4, which is susceptible to impact when the door body 3A is closed, is also stabilized.

[0062] Furthermore, because the door-leading edge member 8A is fixed to the door-leading visible surface 3a of the core material 31c of the door body 3A, it is possible to simultaneously create a protective structure for the door-leading visible surface 3a of the door body 3A as well as for the edge surface 43a on the door-leading side of the tile 4. The face plate portion 81A of the door-leading edge member 8A in this embodiment does not abut against the tile 4, but the face plate portion 81A may abut against the surface 43b of the door-leading end of the tile 4.

[0063] 17, 19, and 21, the trailing edge member 9A is made of a metal molding integrally having a front plate portion 91A covering the surface of the tile 4, a side plate portion 92A covering the edge 44a of the tile 4, a front plate portion 93A covering the trailing edge 3b of the door body 3A, and an interior plate portion 95A disposed on the interior side of the door body 3A. The trailing edge member 9A extends over almost the entire height of the door body 3.

[0064] The front panel portion 91A covers the surface 44b of the trailing edge end of the tile 4. The side panel portion 92A is integral with the front panel portion 91A and extends along the trailing edge side visible surface 3b of the door body 3A so as to cover the edge surface 44a of the tile 4. The visible panel portion 93A is integral with the indoor side end of the side panel portion 92A and extends further toward the indoor side so as to cover the trailing edge side visible surface 3b of the door body 3A. The indoor side panel portion 94A is integral with the indoor side end of the visible panel portion 93A and extends so as to protrude indoors beyond the surface of the indoor panel portion 33 of the door body 3A.

[0065] The indoor-side plate portion 94A integrally includes a hollow portion 941 that protrudes inward in a rectangular shape along the surface of the indoor plate portion 33 of the door main body 3A, and an inner plate portion 942 that extends inward from the indoor-side end of the indoor-side plate portion 94A. The indoor-side plate portion 94A is fixed to the core material 31d on the trailing edge of the door main body 3A at the hollow portion 941 with a plurality of mounting screws SC7. When the door main body 3 is closed, the inner plate portion 942 accommodates a sealing piece (not shown) provided on the central vertical door frame 215 between the hollow portion 941 and the inner plate portion 942. This forms a labyrinth structure, sealing the gap between the door main body 3A and the vertical door frame 215.

[0066] Furthermore, the trailing edge member 9A covers the trailing edge side visible surface 3b of the door body 3A with the visible plate portion 93A, so that it is possible to simultaneously create a protective structure for the trailing edge side visible surface 3b of the door body 3A as well as for the edge surface 44a on the trailing edge side of the tile 4. The face plate portion 91A of the trailing edge member 9A of this embodiment does not abut against the tile 4, but the face plate portion 91A may abut against the surface 43b of the trailing edge of the tile 4 to prevent the trailing edge side of the tile 4 from peeling off from the door body 3A.

[0067] In this way, even in the entrance door 1A consisting of a sliding door, the edge surfaces 41a, 42a, 43a, 44a of the tile 4 provided on the door body 3A are protected by the upper edge member 6A, the lower edge member 7A, the door front edge member 8A, and the door rear edge member 9A, respectively, so that, just like the entrance door 1 consisting of a hinged door, damage to the tile 4 is maintained for a long period of time, improving durability.

[0068] Resin cap members 37a, 37b, 37c, and 37d are provided at the corners of the door main body 3A, as shown in Figures 18 to 21. These cap members 37a, 37b, 37c, and 37d protect the end faces of the edge members 6A, 7A, 8A, and 9A.

[0069] The entrance door 1, 1A described in each of the above embodiments achieves the following advantages. Specifically, the entrance door 1, 1A includes a door body 3, 3A that is openably and closably housed inside a door frame 2, 210 installed in an opening in a building frame, and a tile 4 that is adhered via an adhesive layer 5 to the exterior panel 32 that forms the exterior side of the door body 3, 3A. The tile 4 is installed from the upper end or near the upper end to the lower end of the door body 3, 3A. Because the tile 4 is fixed to the door body 3, 3A by the adhesive layer 5, there is no need to use a fixing part that penetrates the tile 4, as in the past. The surface texture of the entrance door 1, 1A is expressed by the material of the tile 4 itself, so the entrance door 1, 1A has a high design quality due to the natural texture of the tile 4. This further improves the design quality of the entrance door 1, 1A.

[0070] Edge members 6, 7, 8, 9, 6A, 7A, 8A, and 9A are provided on the four sides of the tile 4 to protect the end faces 41a, 42a, 43a, and 44a of the tile 4, respectively. As a result, the end faces 41a, 42a, 43a, and 44a of the tile 4 are protected, so that the damage to the tile 4 is maintained for a long period of time, improving durability.

[0071] In entrance door 1, which is a hinged door whose leading edge can be opened and closed around the hinged side, the edge member includes a leading edge member 8 that covers from the leading edge surface 43b of the tile 4 to the leading edge surface 43a and is fixed to the leading edge surface of the door body 3. The leading edge member 8 has a surface abutment plate portion 81 that abuts against the leading edge surface 43b of the tile 4, and an extension plate portion 82 that is integral with the surface abutment plate portion 81 and extends toward the door frame 2 so as to overlap with the door frame 2. The surface abutment plate portion 81 and the extension plate portion 82 are continuous and flush with each other. This configuration allows the leading edge member 8 to prevent damage to the edge surface 43a of the tile 4 and to secure the leading edge of the tile 4 to the door body 3, preventing the leading edge of the tile 4 from peeling off from the door body 3. Since the surface abutment plate portion 81 and the extension plate portion 82 are provided flush with each other, when the door edge side of the entrance door 1 is viewed from the outside, the door edge side edge member 8 does not appear to protrude significantly. Therefore, the design of the entrance door 1 is not impaired.

[0072] In entrance door 1, which is a hinged door whose door edge can be opened and closed around the hinged side, the edge member includes an upper edge member 6 that covers from the surface 41b of the upper end of tile 4 to the upper edge surface 41a and is fixed to the upper visible surface of door body 3, and a lower edge member 7 that covers from the surface 42b of the lower end of tile 4 to the lower edge surface 42a and is fixed to the lower visible surface of door body 3. As a result, upper edge member 6 and lower edge member 7 prevent damage to the edge surfaces 41a and 42a of tile 4, and by fixing the upper and lower ends of tile 4 to door body 3, it is possible to prevent the upper and lower ends of tile 4 from peeling off from door body 3.

[0073] In the entrance door 1, which is a hinged door whose end side can be opened and closed around the hinge side, the edge member includes a hinge-side edge member 9 disposed on the hinge side of the door body 3. The hinge-side edge member 9 has a front-side abutment plate portion 91 that abuts against the front surface 44b of the tile 4 at the hinge side end, and a back-side abutment plate portion 92 that abuts against the back surface 44c of the tile 4 at the hinge side end and sandwiches the tile 4 between the front-side abutment plate portion 91 and the back-side abutment plate portion 92. The back-side abutment plate portion 92 has the same thickness as the adhesive layer 5. This sandwiches the end of the tile 4 at the hinge side between the front-side abutment plate portion 91 and the back-side abutment plate portion 92, thereby more reliably protecting the edge surface 44a of the tile 4. Because the back-side abutment plate portion 92 has the same thickness as the adhesive layer 5, there is no risk that the back-side abutment plate portion 92 will affect the fixation of the tile 4 by the adhesive layer 5. Since the back surface of the hanging side of the tile 4 is supported by the back surface abutment plate portion 92, the fixed state of the hanging side of the tile 4 is also stable.

[0074] In the entrance door 1A, which is a sliding door that can slide, the edge member includes an upper edge member 6A that covers the upper edge surface 41b of the tile 4 and the upper edge surface 41a, and is fixed to the visible surface of the upper end of the door body 3A. This allows the upper edge member 6A to prevent damage to the edge surface 41a of the tile 4.

[0075] In entrance door 1A, which is a sliding door that can slide, the edge member includes a lower edge member 7A that extends from the surface 42b of the lower end of tile 4 to cover the lower edge surface 42a. The lower edge member 7A is provided integrally with guide groove frame 36 that is provided on the lower end surface of door body 3A. In this way, by fixing guide groove frame 36 to door body 3A, the lower edge member 7A that protects the lower edge surface 42a of tile 4 can be simultaneously constructed.

[0076] In entrance door 1A, which is a sliding door that can slide, the edge members include a leading edge member 8A arranged on the leading edge side of door body 3A and a trailing edge member 9A arranged on the trailing edge side of door body 3A. Leading edge member 8A is arranged to cover from a surface 43b of the leading edge end of tile 4 to a leading edge surface 43a and leading edge surface 3a of door body 3A. Trailing edge member 9A is arranged to cover from a surface 44b of the trailing edge end of tile 4 to a trailing edge surface 44a and trailing edge surface 3b of door body 3A. This makes it possible to simultaneously create a protective structure for leading edge and trailing edge surfaces 43a, 44a of tile 4, as well as a protective structure for leading edge surface 3a and trailing edge surface 3b of door body 3A.

[0077] When exterior tiles 200 are installed around the opening 101 of the building skeleton 100, the tiles 4 may be made of the same material as the exterior tiles 200. This makes it easy to unify the design of the entrance door 1, 1A and the building skeleton 100, further improving the design of the entrance door 1, 1A.

[0078] The door body 3, 3A has a lock 12 with a cylinder 121 and a cylinder cover 13 that covers the cylinder 121. The tile 4 has a mounting hole 45 with a diameter larger than the outer diameter of the cylinder 121. The cylinder 121 is attached to the exterior side of the door body 3, 3A through the mounting hole 45. The mounting hole 45, along with the cylinder 121, is covered by the cylinder cover 13. As a result, not only the cylinders 121, 121 but also the mounting holes 45, 45 are not visible from the exterior, and the design is not impaired.

[0079] The tile 4 of the entrance door 1, 1A described above is composed of a single tile that covers the entire exterior surface of the door body 3, 3A. However, the tile 4 may be divided into multiple pieces.

[0080] Although not shown, the surface on which the tiles 4 are provided is not limited to the exterior side of the door body 3, 3A, but may include surfaces arranged around the door body 3, 3A. For example, if the entrance door 1, 1A has a sleeve panel or a sub-door on the leading edge, the tiles 4 may be adhered to the entire exterior side of the sleeve panel and sub-door using the same structure as the entrance door 1, 1A. Furthermore, the tiles 4 may be adhered to the surface of the door frame.

[0081] To improve the design of the interior side of the door body 3, 3A, the tiles 4 may be provided on the interior side of the door body 3, 3A. The tiles 4 may also be provided on both the exterior and interior sides of the door body 3, 3A. When the tiles 4 are provided on the interior side of the door body 3, 3A, it is desirable to provide the tiles 4 on the interior side with the same edge members as above.

[0082] The tiles 4 as decorative materials adhered to the door bodies 3, 3A are not limited to ceramic tiles, but may be glass, wood, metal tiles, etc. For example, when metal tiles are used as exterior materials for the building frame, adhering the metal tiles to the door bodies 3, 3A makes it easy to unify the design of the entrance doors 1, 1A and the exterior materials of the building frame.
