DETAILED DESCRIPTION OF THE INVENTION

[0009] [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2, wall panel 1 is incorporated into a building to form a wall separating the indoor and outdoor areas. Wall panel 1 includes a panel body 2, an opening frame 3, a frame body 4, four cover members 5, a frame 6, and a shoji screen 7. In the following description, the left-right direction of the wall panel 1 is the X-axis direction, the up-down direction of the wall panel 1 is the Y-axis direction, and the projection direction of the wall panel 1 is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] The panel body 2 is constructed by arranging a panel 21 within a frame having upper and lower horizontal members and left and right vertical members. The panel 21 is arranged to form an opening in the panel body 2, and is constructed from a load-bearing surface material such as particle board made by overlapping multiple wooden boards.

[0011] The opening frame 3 includes a lintel 31 as an upper member that defines the opening 30, a window sill 32 as a lower member, and left and right vertical members 33. The opening frame 3 is provided on the indoor side of the panel 21 so that the opening 30 communicates with the opening in the panel 21.

[0012] The lintel 31 comprises an exterior observation surface 311, an intermediate observation surface 312 extending downward along the Y-axis direction from the interior end of the exterior observation surface 311, an intermediate observation surface 313 extending from the lower end of the intermediate observation surface 312 toward the interior of the room along the Z-axis direction, a lower interior observation surface 314 extending upward along the Y-axis direction from the interior end of the intermediate observation surface 313, and an interior observation surface 315 extending from the upper end of the lower interior observation surface 314 toward the interior of the room along the Z-axis direction.

[0013] The window sill 32 comprises an exterior observation surface 321, a first intermediate observation surface 322 located above the exterior observation surface 321 and on the interior side, an intermediate observation surface 323 extending upward along the Y-axis direction from the interior end of the first intermediate observation surface 322, a second intermediate observation surface 324 extending from the upper end of the intermediate observation surface 323 toward the interior along the Z-axis direction, an upper interior observation surface 325 extending downward along the Y-axis direction from the interior end of the second intermediate observation surface 324, and an interior observation surface 326 extending from the lower end of the upper interior observation surface 325 toward the interior along the Z-axis direction.

[0014] The left and right vertical members 33 have an exterior observation surface 331, an intermediate observation surface 332 extending inward from the interior end of the exterior observation surface 331 along the X-axis direction, an intermediate observation surface 333 extending from the interior end of the intermediate observation surface 332 toward the interior of the room along the Z-axis direction, and an interior observation surface 334 extending outward from the interior end of the intermediate observation surface 333 along the X-axis direction.

[0015] The panels 21 abut against the exterior facing surfaces of the lintel 31, window sill 32 and left and right vertical members 33. The exterior-facing surface 311 and intermediate-facing surface 313 of the lintel 31, the exterior-facing surface 321 and first and second intermediate-facing surfaces 322, 324 of the window sill 32, and the exterior-facing surfaces 331 and intermediate-facing surfaces 333 of the left and right vertical members 33 form the inner peripheral surface of the opening 30 of the opening frame 3. Between the exterior-facing surfaces 311, 322, 331, which are the exterior portions of the inner peripheral surface of the opening 30, and the interior-facing surfaces 313, 324, 333, which are the interior-facing portions, intermediate-facing surfaces 312, 323, 332 are provided so as to extend from the exterior-facing surfaces 311, 322, 331 to the inside of the opening 30. The lintel 31, window sill 32, and left and right vertical members 33 are formed so that the intermediate sighting surfaces 312, 323, and 332 are located on the same plane, and the lower interior sighting surface 314, upper interior sighting surface 325, and interior sighting surface 334 (hereinafter sometimes referred to as "indoor sighting surfaces 314, 325, and 334") are located on the same plane. In other words, the lintel 31, window sill 32, and left and right vertical members 33 are formed so that the lengths in the Z-axis direction from the intermediate sighting surfaces 312, 323, and 332 to the indoor sighting surfaces 314, 325, and 334 are the same.

[0016] The frame body 4 is made up of an upper frame 41, a lower frame 42, and left and right vertical frames 43. The upper frame 41, the lower frame 42, and the left and right vertical frames 43 are made up of extruded aluminum members.

[0017] The upper frame 41 is installed along the lintel 31. The upper frame 41 is fixed to the lintel 31 with a plurality of screws 44 that penetrate the visible surface 411 and the exterior visible surface 311. In other words, the upper frame 41 is provided along the indoor portion of the inner circumferential surface of the opening 30. As shown in FIGS. 1 and 3(A), the upper frame 41 includes an extension portion 412 that extends upward along the Y-axis direction from the indoor end of the visible surface 411 and then extends indoors along the Z-axis direction, a sight piece 413 that extends upward along the Y-axis direction from the indoor end of the extension portion 412, a contact portion 414 that protrudes downward from the indoor end of the extension portion 412, and an engagement piece 415 that protrudes indoors from the connection portion between the extension portion 412 and the sight piece 413.

[0018] The lower frame 42 is installed along the window sill 32. The lower frame 42 has legs 421 that rest on the exterior-facing visible surface 331 and the first intermediate visible surface 322 of the window sill 32. In other words, the lower frame 42 is provided along the interior-facing portion of the inner circumferential surface of the opening 30. As shown in Figures 1 and 3(B), the lower frame 42 has a sight piece 422 that extends upward along the Y-axis direction from the interior-facing end of the leg piece 421, and an engagement piece 423 that protrudes into the interior from a position below the upper end of the sight piece 422. The portion of the sight piece 422 that protrudes upward from the connection with the engagement piece 423 forms an abutment 424.

[0019] The left and right vertical frames 43 are arranged along the left and right vertical members 33, respectively. The left and right vertical frames 43 are fixed to the left and right vertical members 33 with a plurality of screws 45 that penetrate the inward facing surface 431 and the exterior outward facing surface 331. In other words, the left and right vertical frames 43 are provided along the indoor-side portion of the inner circumferential surface of the opening 30. As shown in FIGS. 1 and 3(C), the left and right vertical frames 43 include a sight piece 432 that extends outward along the X-axis direction from the indoor-side end of the inward facing surface 431, and an engagement piece 433 that protrudes indoors from a position on the sight piece 432 outside the connection portion with the inward facing surface 431. The indoor-side end of the inward facing surface 431 forms an abutment portion 434.

[0020] The four cover materials 5 are attached to the lintel 31, the window sill 32, and the left and right vertical members 33 of the opening frame 3, one each. Each cover material 5 is made of resin and has an L-shaped cross section, and includes a cover portion 51 on the visible side of the room and a cover portion 52 on the inner periphery.

[0021] Each of the interior sight surface cover portions 51 is formed in a plate shape that can cover almost the entire interior sight surface 314 , 325 , 334 of the opening frame 3 . Each inner surface cover portion 52 is capable of covering the entire intermediate projection surface 313, the second intermediate projection surface 324 and the intermediate projection surface 333 (hereinafter sometimes referred to as "each intermediate projection surface 313, 324, 333") in the opening frame 3, that is, the entire outdoor portion of the inner surface of the opening 30, and is formed in the shape of a plate whose length in the Z-axis direction is longer than that of each intermediate projection surface 313, 324, 333. As shown in Figures 3(A), (B), and (C), the end of each inner peripheral cover portion 52 on the side not connected to the interior sight-surface cover portion 51 is provided with an opposing portion 53 extending in the same direction as each interior sight-surface cover portion 51, and a soft piece 54 protruding in a direction away from each interior sight-surface cover portion 51. A protruding piece 55 protruding in a direction away from each interior sight-surface cover portion 51 is provided at the tip of each opposing portion 53. The soft piece 54 is made of a material softer than the cover material 5. The opposing portion 53, the soft piece 54, and the protruding piece 55 form an engaging recess 56 into which each engaging piece 415, 423, and 433 engages. The surfaces of each interior visible surface cover portion 51 and each inner peripheral surface cover portion 52 facing the opening frame 3 are provided with a plurality of ribs 57 extending parallel to the length of the lintel 31, window sill 32 and vertical member 33.

[0022] As shown in Figures 1 and 3(A), one cover material 5 has the engagement piece 415 of the upper frame 41 engaged with the engagement recess 56, and each rib 57 abutting the middle visible surface 313 of the lintel 31 and the lower indoor visible surface 314, and the upper end portion of the indoor visible surface cover part 51 is fixed to the lower indoor visible surface 314 by a plurality of screws 58 as fixing devices attached from the inside of the room. As shown in Figures 1 and 3(B), the other cover material 5 has the engagement piece 423 of the lower frame 42 engaged with the engagement recess 56, and each rib 57 abutting the second intermediate visible surface 324 of the window sill 32 and the upper indoor visible surface 325, and the lower end portion of the indoor visible surface cover part 51 is fixed to the upper indoor visible surface 325 by a plurality of screws 58 attached from the inside of the room. As shown in Figures 1 and 3(C), the remaining two cover materials 5 have the engaging pieces 433 of each vertical frame 43 engaged with each engaging recess 56, and each rib 57 abutting the intermediate visible surface 333 and the indoor visible surface 334 of each vertical member 33, and the outer parts of each indoor visible surface cover part 51 in the X-axis direction are fixed to the indoor visible surface 334 by multiple screws 58 attached from the inside of the room. In this way, the engagement pieces 415, 423, 433 of each frame 41, 42, 43 engage with the engagement recesses 56 of each cover material 5, thereby preventing the inner surface cover portion 52, which is not fixed to each intermediate prospective surface 313, 324, 333, from deforming in a direction away from each intermediate prospective surface 313, 324, 333.

[0023] The engaging pieces 415, 423, and 433 engage with the engaging recesses 56 with a gap formed between the protruding piece 55 and the engaging pieces 415, 423, and 433. The engaging pieces 415, 423, and 433 also engage with the engaging recesses 56 with the soft pieces 54 abutting against the abutting portions 414, 424, and 434 and the engaging pieces 415, 423, and 433, respectively. With at least one of these configurations, even if a shape error occurs in at least one of the frames 41, 42, and 43 and the cover materials 5, the engaging pieces 415, 423, and 433 can be engaged with the engaging recesses 56.

[0024] The facing portion 53 of each cover material 5 faces the outdoor side of each intermediate sighting surface 312, 323, 332. Therefore, even if the cover material 5 shifts indoors relative to the opening frame 3 when the cover material 5 is fixed to the opening frame 3, the abutment between the facing portion 53 and the intermediate sighting surface 312, 323, 332 can prevent the cover material 5 from shifting.

[0025] The frame 6 is composed of an upper frame 61, a lower frame 62, and left and right vertical frames 63 that are fixed in positions facing the lower interior visible surface 314 of the lintel 31, the upper interior visible surface 325 of the window sill 32, and the interior visible surfaces 334 of the left and right vertical members 33. The upper frame 61, the lower frame 62, and the left and right vertical frames 63 are fixed in place so as to abut against the respective cover materials 5 and cover the respective screws 58 that fasten to the lintel 31, the window sill 32, and the left and right vertical members 33.

[0026] The shoji screen 7 is placed within the opening 30 of the opening frame 3 and is composed of a frame body 74 consisting of an upper frame 71, a lower frame 72, and left and right vertical frames 73 formed from extruded resin profiles, and a surface material 75 such as a glass panel placed within the frame body 74.

[0027] According to the above embodiment, the cover material 5 is fixed not by fixing the cover material 5 to the frame body 4 with fasteners such as screws, but by engaging the inner surface cover portion 52 with the frame body 4 and by fixing the indoor visible surface cover portion 51 to the indoor visible surfaces 314, 325, 334 of the opening frame 3 with screws 58, thereby suppressing the occurrence of condensation. Since the frame 6 is fixed so as to cover the screws 58 that fix the cover material 5 to the opening frame 3, deterioration in the design of the wall panel 1 can be suppressed. Since the frame 4 is made of metal and the cover material 5 is made of resin, the heat insulating properties of the wall panel 1 can be improved.

[0028] [Variations] Although the frame body 4 and the cover material 5 are fixed to each other by engaging the engaging pieces 415, 423, 433 of the frame body 4 with the engaging recessed parts 56 of the cover material 5, it is also possible to use locking between the frame body 4 and the cover material 5. An example of such a locking configuration is a configuration in which the engaging pieces 415, 423, 433 are locked with the protruding pieces 55 without providing the soft pieces 54 on the cover material 5. The frame 4 may be provided with an engaging recess, and the cover 5 may be provided with an engaging piece that engages with the engaging recess. The wall panel 1 does not need to have a frame 6. The cover material 5 may be made of metal. The facing portion 53 constituting the engaging recess 56 may be provided so as not to be positioned on the outdoor side of the intermediate sight surfaces 312, 323, 332.
