Summary of the Invention

Problems to be Solved by the Invention

[0005] According to such prior art, although the surface material of the melamine resin decorative board has a rich design, since it is a printed matter, there is a limit in the expression of texture. Also, even if painting treatment is performed only on the edge portion or LVL is arranged, it is difficult to exceed the impression given by the surface material that occupies most of the visual field, and there is a problem that there is still room for further improvement in the overall design quality.

[0006] Therefore, in view of the problems of the prior art, the object of this invention is to provide a panel that can improve the overall design by unifying the visible appearance with that of actual wood and achieving a superior sense of unity, and a toilet booth using the same panel, by using OSB (Oriented Strand Board) for the surface material and edge material. [Means for solving the problem]

[0007] The invention of claim 1 of this application, which aims to achieve this objective, comprises upper and lower left and right LVL frame members, a paper honeycomb core member placed inside the frame members, OSB end members attached to at least one outer surface of the left and right frame members, and OSB surface material bonded to both sides of the frame members, core member, and end members. The end members are formed by laminating plates of the same specifications and thickness as the surface material and arranging them perpendicular to the surface material, so that the entire surface visible from the outside is OSB.

[0008] Furthermore, the surface material and end-piece material can be made to protrude above the upper frame material, and upward mounting grooves can be formed above the upper frame material, while downward mounting grooves can be formed on the lower surface of the lower frame material.

[0009] The structure of the invention of claim 4 comprises top, bottom, left, and right LVL frame members, a paper honeycomb core member placed inside the frame members, OSB end members attached to the outer surfaces of the left and right frame members, and an OSB surface material bonded to both sides of the frame members, core member, and end members. The end members are formed by laminating plates of the same specifications and thickness as the surface material and arranging them perpendicular to the surface material, so that the entire surface visible from the outside is OSB.

[0010] The gist of the invention of claim 5 is that any panel from claims 1 to 3 is used as a side panel, the panel of claim 4 is used as a door panel, and both sides of the partition panel for the private room are made of OSB surface material.

[0011] Furthermore, the outer surface of the OSB panels, door panels, and partition panels can be finished with a clear coating using polyurethane paint. [Effects of the Invention]

[0012] When the invention of claim 1 is constructed as described above, the end grain of the OSB is formed by laminating a board material of the same specifications as the OSB surface material and forming it together with the surface material on a predetermined end surface, thereby achieving the texture of real wood that is integrated with the surface material for the entire visible appearance, and significantly improving the overall design. When the end grain of the OSB is attached to only one of the left and right frame members, the frame member without the end grain is connected to, for example, the wall surface of a building or the surface of another panel, and in this case, it is preferable to take care to conceal members other than the OSB or to expose them only slightly to the outside.

[0013] The mounting grooves formed above the upper frame material by the surface material and end-edge material can be used, for example, to house ceiling rails and fix the upper end of the panel to the ceiling surface of the building. Both ends of the mounting grooves are closed with end-edge material, so there is no risk of the overall appearance of the OSB being spoiled.

[0014] The mounting groove on the underside of the lower frame material is used to house, for example, an adjuster component for adjusting the height on the floor surface, and to set the lower edge of the panel to the floor surface together with an appropriate baseboard. Furthermore, both ends of the mounting groove can be neatly closed using end pieces.

[0015] When the configuration of the invention of claim 4 is used, the OSB end grain pieces attached to each of the left and right frame members, together with the OSB surface material, can achieve the same effects as the invention of claim 1.

[0016] When the configuration of the invention of claim 5 is used, the overall appearance of the visible side panels, door panels, and partition panels can be unified to match the texture of real wood using OSB, and a good design with a strong sense of unity as a whole can be reliably achieved.

[0017] In addition, the clear coating finish of the polyurethane paint can improve the necessary water resistance and surface strength without damaging the appearance and texture of the OSB of each panel.

Modes for Carrying Out the Invention

[0019] Hereinafter, embodiments of the invention will be described with reference to the drawings.

[0020] The toilet booth includes sleeve panels 11, 12, 13, door panels 14, 15, and partition panels 16, 16 (Figures 1 and 2). However, a shielding screen panel 17 is attached to the toilet booth. Figures 2(A) and (B) are elevation views corresponding to the views in the X and Y directions of Figure 1, respectively.

[0021] The toilet booth utilizes the right-angled wall surfaces W, W of the building to form individual rooms R, R through the partition panels 16, 16. On the front side of the individual rooms R, R, inward-opening and outward-opening door panels 14, 15 are equipped together with the sleeve panels 11, 12, 13. In addition, the screen panel 17 is erected parallel to the partition panels 16, 16.

[0022] The side panels 11, 12, 13 and the screen panel 17 are erected between the floor surface F and the ceiling surface C of the building via baseboards 21 and ceiling rails 22, respectively, and the same applies to each partition panel 16. The door panels 14 and 15 are formed to be shorter vertically than the side panels 11, 12, and 13, and large and small gaps are formed between the upper and lower ends of the door panels 14 and 15 and the ceiling surface C and floor surface F, respectively. One end of each side panel 13, each partition panel 16, and screen panel 17 is connected to the wall surface W via connecting rails 23, and the other ends of the partition panels 16 are connected to the surfaces of the side panels 11 and 12, respectively, via connecting members (not shown).

[0023] Door panels 14 and 15 are supported so as to be able to rotate horizontally via upper and lower pivot hinges 24a and 24b, respectively. Door panels 14 and 15 are also fitted with an exterior handle 25a and an interior slide bolt 25b, respectively, and a locking catch 25c is fixed to the side panel 11 or side panel 13 in front of each slide bolt 25b.

[0024] The side panels 11, 12, 13, door panels 14, 15, partition panels 16, 16, and screen panel 17 basically share a common flush panel structure. Therefore, the structure of panel 30 of the side panel 11, which is located between door panels 14 and 15, is as shown in Figure 3, for example. However, Figure 3(A) is a partially broken schematic front view, and Figures 3(B) and (C) are the longitudinal and transverse cross-sectional views of Figure 3(A), respectively.

[0025] Panel 30 is composed of top, bottom, left, and right LVL frame members 31, 31, 32, 32, a paper honeycomb core member 33, OSB end pieces 34, 34 on the outer surfaces of the left and right frame members 32, 32, and OSB surface materials 35, 35 on both sides. The core member 33 is positioned inside the frame members 31, 31, 32, 32, and the surface materials 35, 35 are bonded to both sides of the frame members 31, 31, 32, 32, the core member 33, and the end pieces 34, 34.

[0026] The end pieces 34, 34 and surface pieces 35, 35 each protrude above the upper frame piece 31, and an upward-facing mounting groove 36a is formed above the upper frame piece 31. A downward-facing installation groove 36b is formed on the lower surface of the lower frame piece 31, and both ends of the mounting groove 36a and installation groove 36b are closed via the upper and lower ends of the end pieces 34, 34, respectively. The mounting groove 36a houses the ceiling rail 22 (Figure 2), and the installation groove 36b houses an adjuster member (not shown) that is combined with the baseboard 21.

[0027] The outer surfaces of each end-piece material 34, together with the edges of the surface materials 35, 35, are formed as end-piece surfaces 37a and 37b with predetermined cross-sectional shapes (Figures 1 and 3(C)). Specifically, the end-piece surface 37a facing the door edge side of the inward-opening door panel 14 is formed with a left-right asymmetrical cross-sectional shape, where the interior side of the room R is straight and the exterior side is a smooth concave semi-circular arc, with the exterior side being higher than the interior side. The end-piece surface 37b facing the hinge side of the door panel 15 is formed with a left-right symmetrical cross-sectional shape, a smooth concave arc.

[0028] Each end-edge material 34 is constructed by laminating multiple OSB boards 34a, 34a… to the outer surface of the left or right frame material 32 (Figure 4). However, Figure 4(A) is a schematic front view of a partial break before the end faces 37a, 37b are formed on the outer surfaces of the end-edge materials 34, 34, and Figures 4(B) to (D) are the left side view, longitudinal section view, and top view of Figure 4(A), respectively. The boards 34a, 34a… are the same specifications as the OSB surface material 35, and are cut to the same width as the depth of each frame material 31, 32, and then laminated perpendicular to the surface material 35, 35.

[0029] The end faces 37a and 37b can be formed in one step by cutting the outer surface of the end material 34 using dedicated milling cutters F1 and F2, respectively (Figures 5(B) and (C)). However, Figure 5(A) is a magnified cross-sectional view of the main part of Figure 4(A) showing the end portion of the panel 30 before cutting, and Figures 5(B) and (C) are diagrams showing the cutting procedure for the end faces 37a and 37b, respectively. Note that the number of layers of plate material 34a, 34a... of the end material 34 and the number of layers to be cut do not necessarily have to be as shown in Figures 4 and 5, and can be changed as appropriate.

[0030] The structure of the panels 30 of door panels 14 and 15 is as shown in Figure 6, for example. The panel 30 in Figure 6 differs from the panel 30 of the side panel 11 in Figure 3 in that it lacks the upper and lower mounting grooves 36a and installation grooves 36b, and the outer end faces 37c of each end piece 34 have a symmetrical, smooth, convex arc-shaped cross-section. Otherwise, it is constructed similarly. The end faces 37c can also be machined according to Figure 5. However, Figures 6(A) to 6(C) correspond to Figures 3(A) to 6(C), respectively.

[0031] The side panel 12 has a symmetrical end face 37b on the side facing the hinge side of the door panel 14 (Figures 1 and 7(A)), and a straight end face 37d on the other side that connects to the partition panel 16 at a right angle (Figures 1 and 7(C)). However, the end face 37d is asymmetrical, with the side in contact with the partition panel 16 being at a right angle and the opposite side being rounded and chamfered. The side panel 13 has an asymmetrical end face 37a on the side facing the door edge side of the door panel 15 (Figures 1 and 7(B)), and on the opposite side that connects to the wall W, there is no end piece 34, and a mounting groove 38b for housing the connecting rail 23 is formed on the outer side of the frame material 32 (Figures 1 and 7(F)). Note that the end face 37a of the side panel 13 is lower on the exterior side of the private room R and higher on the interior side in order to accommodate the outward-opening door panel 15.

[0032] Each partition panel 16 and screen panel 17 does not have an end piece 34 on the side that connects to the wall surface W, and a mounting groove 38b for the connecting rail 23 is formed on the outer surface of the frame material 32 (Figures 1 and 7(F)). Similarly, on the side of each partition panel 16 that connects to the surface of the sleeve panels 11 and 12, there is no end piece 34, and a mounting groove 38a for a connecting member (not shown) is formed on the outer surface of the frame material 32 (Figures 1 and 7(E)). On the other hand, the open end of the screen panel 17 is formed as a symmetrical, straight end face 37e with rounded chamfers at both ends, via the end piece 34 and surface material 35, 35 (Figures 1 and 7(D)).

[0033] Therefore, the left and right end grain pieces 34, 34 are equipped on both the side panels 11, 12 and the door panels 14, 15, but one side of the side panel 13 and the screen panel 17 on the wall W side is omitted, and both sides of the partition panels 16, 16 are omitted. On the other hand, the entire surface of the side panels 11, 12, 13, the door panels 14, 15, each partition panel 16, and the screen panel 17 that is visible from the outside is made of OSB, and the outer surface of these OSBs is finished with a clear coating of polyurethane paint. Thus, the entire exterior of the toilet booth, excluding the wall W, W of the building, is made of actual wood OSB, and a good texture can be achieved.

[0034] In the above description, the number of individual toilet stalls R may be one or more, the door panels 14 and 15 may be either inward-opening or outward-opening, or both may be mixed as appropriate. Furthermore, the toilet stalls may be installed along the straight sections of the building walls W, instead of along the curved sections of the walls W, and the screen panel 17 may be omitted or two or more may be placed as appropriate.

[0035] Furthermore, the inward-opening door panel 14 may incorporate a movable shielding device 27 in a vertical groove 37c1 provided on the end face 37c on the door edge side, in case of emergencies such as the user falling inside the private room R (Figure 8). The end face 37c with the vertical groove 37c1 can also be machined according to Figure 5. However, Figures 8(A) and (B) are enlarged schematic cross-sectional views of the main parts and enlarged cross-sectional views of the main parts of the door panel 14 excluding the shielding device 27, respectively.

[0036] When the door panel 14 is closed normally, the shielding device 27 has a cover material 27a that protrudes toward the side panel 11, shielding the gap g from view. However, when the door panel 14 is opened outwards by retracting the slide bolt 25b to the emergency unlock position (dotted line in Figure 8(A)) from the outside using the emergency unlocking mechanism in the handle 25a, the cover material 27a sinks toward the base material 27b in the vertical groove 37c1 against the leaf spring 27c, allowing the door panel 14 to open outwards (see Japanese Patent Publication No. 7204839). However, the slide bolt 25b can be switched between the locked position (dotted line in Figure 8(A)) and the unlocked position (solid line) from the inside relative to the front catch 25c, and in the unlocked position, it acts as a door stop when closing the door panel 14.

[0037] A decorative sticker that faithfully represents the OSB of each surface material 35 and edge material 34 is attached to the outer surface of the cover material 27a of the shielding device 27, ensuring a sense of unity with the surface material 35, 35 and edge material 34. [Industrial applicability]

[0038] This invention can unify the visible surface of each panel to resemble the appearance of real wood using OSB, achieving a superior sense of unity and a good texture, and can be widely and suitably applied to toilet booths installed in any building. [Explanation of symbols]
