Description

[Technical field]

[0001] The present invention relates to the technical field of a panel body provided to divide an indoor space to form a toilet booth or the like, and a method for manufacturing the panel body. [Background technology]

[0002] Generally, a panel body is used as a member for partitioning a booth (small room) such as a toilet booth, which is constructed by inserting a filler such as a paper core between first and second panels (indoor and outdoor panels) serving as front and back panels, but there are cases where it is required to configure such a panel body with an external device such as a terminal device for a remote control system or a sound simulating device, and if an external device is attached to the first panel, which is the indoor side panel of the panel body, in order to meet this requirement, the external device will be disposed in a protruding state from the surface of the panel body, which not only mars the appearance but also causes problems such as people or luggage easily bumping into the protruding external device and making it easy for it to be vandalized. Therefore, it is proposed to hollow out the first panel of the panel body and the filler to form a groove-like space, and to incorporate the external device in this space. However, when attempting to hollow out and remove the first panel and the filler to form the space, there is a problem in that the work of forming the space is tedious, complicated, and poor in efficiency because the filler and the first panel are bonded together. Incidentally, when manufacturing such a panel body, if it is desired to have a space for forming a window, it has been proposed to form the panel body with the space removed in advance (see, for example, Patent Document 1).

[0004] When forming a space as in the conventional method described above, it is proposed to manufacture the panel body in a state in which the first panel and filler in the space portion of the second panel, which will become the exterior side panel, are removed in advance, while leaving the space portion intact. Such panel bodies are generally manufactured by pressing (known press processes include hot pressing and cold pressing, depending on the type of adhesive) with a filler (including crosspiece material) placed between the first and second panels to which adhesive has been applied. However, when manufactured by this type of pressing, the area of ​​the second panel where there is no filler (where the filler has been removed) is not bonded to the filler by the press, and therefore does not have the same tension as an area where there is filler and is bonded. In addition, the filler is missing from the peripheral area of ​​the opening in the first panel, making it weak and prone to deformation, and these are problems that the present invention aims to solve.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a toilet booth (a private room for a toilet), which is composed of various members and devices such as left and right front (front) panel bodies 2 forming an entrance E, a depth panel body 3 provided between a wall part W and the front panel body 2, and a door body 4 for opening and closing the entrance E, all of which are conventional. In this embodiment, a groove-shaped space 6 is formed in the depth panel body 3 for mounting the external device 5 of the present invention therein, and hereinafter, except where necessary, the "depth panel body" in which the space 6 is formed will be referred to simply as the "panel body" unless there is a need to express it as a "depth panel body." In this embodiment, the depth panel body 3 is constructed by connecting two panel bodies, a panel body 3 on the wall W side and a panel body 3 on the front panel body 2 side, in a continuous manner, and the external device 5 is provided on the panel body 3 on the wall W side.

[0009] The panel body 3 comprises frame members 7 on all four sides, a filler material 8 made of a material such as a paper core material which is interposed in the space surrounded by the frame members 7, a first panel 9 on the inside of the booth room which constitutes the front and back panels (face material), a second panel 10 on the outside of the booth room, and cross bars 11 which are interposed between the frame members 7 on the left and right, and the panel body 3 is formed by bonding the first and second panel members 9, 10 together with the frame members 7, filler material 8 and cross bars 11 which are interior materials, using an adhesive (not shown). In addition, as shown in FIG. 5, the panel body 3 in this embodiment may further include a decorative panel 16 made of melamine or the like on the surface of both the first and second panel 9, 10, or on the surface of any selected panel 9 or 10, if necessary.

[0010] In the panel body 3 constructed in this manner, an opening 9a is formed in the first panel 9 by removing the opening-equivalent portion 9b of the first panel 9 and the filler 8 so that the opening faces the inside of the booth room at a position lower than the central portion in the vertical direction and at the central portion (middle portion) in the horizontal direction, and a space portion (storage portion) 6 which is a groove-like space with the second panel 10 as the bottom portion is formed, and in this embodiment, horizontal bars 11 are provided at both the upper and lower end edges of the space portion 6. Thus, the space 6 is formed at an appropriate position in the left-right intermediate portion of the portion separated by the horizontal bars 11 from above and below. In this case, an auxiliary member 12 is incorporated in the portion corresponding to the space 6. The auxiliary member 12 has an auxiliary surface portion 12a that is arranged in abutting contact with the inner surface of the second panel 10, and an auxiliary bar portion 12c formed on the periphery that forms the entire top-bottom, left-right periphery of the space 6 by being interposed between the first and second panels 9, 10. In this case, the auxiliary rail portion 12c is formed in a U-shape having a first auxiliary rail surface portion 12d extending flatly from the end edge portion 12b of the auxiliary surface portion 12a, a second auxiliary rail surface portion 12f bent from the tip portion 12e of the first auxiliary rail surface portion 12d toward the first panel 9, and a third auxiliary rail surface portion 12h bent from the tip portion 12g of the second auxiliary rail surface portion 12f toward the space portion 6 while following the first panel 9.

[0011] In this case, the space 6 has an opening 9a formed in the first panel 9 in the shape of a dovetail that is smaller (narrower) than the size (size and area) of the space 6, and therefore the auxiliary surface portion 12a is wider in the vertical and horizontal directions than the opening 9a, and the auxiliary rail portions 12c are formed extending from the vertical and horizontal edge portions (tips) 12b of this wide auxiliary surface portion 12a. When the auxiliary member 12 is formed by bending a single flat plate-like material (planar material, flat plate material (plate), planar material (plate)) 13, a metal plate such as an iron plate or stainless steel plate is suitable as the material for the flat plate material 13 from the standpoints of strength, moisture resistance, ease of processing, etc., but it is of course also possible to use a hard resin plate made of polypropylene, polystyrene, acrylic resin, etc. that undergoes plastic deformation when bent to maintain the bent state.

[0012] Next, a method of forming the auxiliary member 12 having the auxiliary rail portions 12c extending from the auxiliary surface portion 12a on the left and right sides using a flat plate material 13 will be described. As described above, the flat plate material 13 is configured to include an auxiliary surface equivalent portion 13a which corresponds to the auxiliary surface portion 12a and is wider than the opening 9a, and an extension portion 13c which extends (prolongs) in a planar manner from an edge portion 13b of the auxiliary surface equivalent portion 13a in the up, down, left and right directions outward to form the auxiliary rail portion 12c. The extension portion 13c includes a first auxiliary rail surface equivalent portion 13d extending from the edge portion 13b, a second auxiliary rail surface equivalent portion 13f extending from a tip portion 13e of the first auxiliary rail surface equivalent portion 13d, and a third auxiliary rail surface equivalent portion 13h extending from a tip portion 13g of the second auxiliary rail surface equivalent portion 13f. Incidentally, on the assumption that the external device 5 incorporated in the space 6 is an electric component that operates by receiving an external power source, the second auxiliary rail surface equivalent portion 13f on one side in the left-right direction has a hole drilling portion 13i formed at a portion corresponding to the wiring hole 12i described above in order to pass therethrough wiring (not shown) for supplying an external power source to the external device 5. The wiring (power cord) is designed to pass through a tubular member 14 provided to pass through the panel body 3 including the wiring hole 12i.

[0013] Then, the flat plate material 13 is left flat without bending the tip 13b of the auxiliary surface equivalent portion 13a, and the tip 13e of the first auxiliary rail surface equivalent portion 13d and the tip 13g of the second auxiliary rail surface equivalent portion 13f are each valley-folded toward the first surface portion 9, so that the auxiliary surface equivalent portion 13a becomes the auxiliary surface portion 12a, and the first auxiliary rail surface equivalent portion 13d becomes the first auxiliary rail extending flat from the end edge portion 12b of the auxiliary surface portion 12a. The first auxiliary railing surface equivalent portion 13f is bent from the tip 12e of the first auxiliary railing surface portion 12d toward the first panel 9 side to become the second auxiliary railing surface portion 12f, and the third auxiliary railing surface equivalent portion 13h is bent from the tip 12g of the second auxiliary railing surface portion 12f toward the opening 9a side while following the first panel 9, and in this manner the auxiliary member 12 is formed by bending the flat plate material 13.

[0014] The panel body 3 is formed by pressing using the auxiliary member 12 formed in this manner. When pressing the panel body 3, generally, the first panel 9 is covered by the second panel 10 with the necessary interior materials such as the frame material 7, filler material 8, and cross rails 11 assembled into the second panel 10, and then the panel body 3 is pressed. In this case, an adhesive (not shown) is applied to the inner surfaces of the first and second panels 9, 10, and the press process (which may involve various types of press processes, such as hot press and cold press, depending on the type of adhesive) bonds the first and second panels 9, 10 and the interior materials such as the filler material 8 under pressure, thereby forming the panel body 3 in which the first and second panels 9, 10 and the interior materials are bonded together. As this process employs a conventionally known method, detailed explanations will be omitted.

[0015] As described above, in the case where the space 6 is formed in the panel body 3, when the interior material such as the filler 8 before pressing is assembled into the second panel 10, the auxiliary member 12 is assembled into the corresponding portion, and the auxiliary surface portion 12a is also filled with the filler (auxiliary filler for the space) 8a, and then the panel body 3 is formed by pressing. In this case, since the auxiliary member 12 is provided with the auxiliary rail portion 12c, the auxiliary filler 8a does not need to be large enough to fit deeply into the edge portion 12b of the auxiliary surface portion 12a, and can be made to be equivalent in size to the opening 9a, but in this case, it is preferable to simply temporarily fix the auxiliary filler 8a with, for example, a double-sided adhesive tape with weak adhesive power so that the auxiliary filler 8a does not accidentally shift position, as this makes it easier to remove the auxiliary filler 8a, as will be described later. Incidentally, the auxiliary filler 8 a can be incorporated into the auxiliary member 12 either before or after the auxiliary member 12 is incorporated into the second panel 10 .

[0016] When the press working is performed, the auxiliary surface portion 12a and the first auxiliary rail surface portion 12d are adhered to the second panel 10, and the space filling material 8a and the third auxiliary rail surface portion 12h are adhered to the first panel 9. After press molding, when cutting and removing the opening equivalent portion 9b of the first panel 9, which corresponds to the opening 9a of the space portion 6, the auxiliary filling material 8a is adhered to the opening equivalent portion 9b, so that the auxiliary filling material 8a can be removed at the same time as cutting out the opening equivalent portion 9b.

[0017] In the embodiment of the present invention configured as described above, the panel body 3 is configured by bonding together the first and second panels 9, 10 and the filler 8 interposed between the first and second panels 9, 10. The first panel 9 has a groove-like space 6 with an opening 9a formed therein. The auxiliary member 12 is assembled in the area corresponding to the space 6 and includes an auxiliary surface portion 12a disposed on the inner surface of the second panel 10 and an auxiliary rail portion 12c interposed between the first and second panels 9, 10 at the periphery of the space 6. As a result, when the auxiliary filler 8a is assembled in the area corresponding to the space 6, The panel body 3 can be formed by pressing in this state, thereby preventing the peripheral portion of the space portion 6 in the first panel 9 from becoming loose, and when the opening equivalent portion 9b of the first panel 9 is cut away to be removed, the auxiliary filler 8b can be easily removed, not only improving workability, but also the space portion 6 incorporates the auxiliary member 12 having the auxiliary surface portion 12a and the auxiliary rail portion 12c, which has excellent waterproofing and prevents deformation due to water absorption, and the auxiliary rail portion 12c can also reinforce the peripheral portion of the opening 9a of the first panel 9. Moreover, in this structure, the auxiliary rail portions 12c are arranged on the periphery of the space portion 6 on all four sides, so that the space portion 6 can be reliably protected on all four sides.

[0018] In this way, the panel body 3 has a space 6 formed therein in which the auxiliary member 12 is incorporated. The auxiliary member 12 is formed using a single flat plate material 13. In this case, the auxiliary rail portion 12c is formed by bending the extension portion 13c which extends in a planar manner from the edge portion 13b of the auxiliary surface equivalent portion 13a which corresponds to the auxiliary surface portion 12a. This simplifies the production of the auxiliary member 12, thereby improving workability.

[0019] In this case, the auxiliary rail portion 12c is formed with a first auxiliary rail surface portion 12d extending from the edge portion 12b of the auxiliary surface portion 12a, a second auxiliary rail surface portion 12f bent from the tip portion 12e of the first auxiliary rail surface portion 12d toward the first panel 9, and a third auxiliary rail surface portion 12h bent from the tip portion 12g of the second auxiliary rail surface portion 12f toward the space portion 6 while following the first panel 9, and the auxiliary rail portion 12c can be easily formed by being provided in a U-shape on the outside of the auxiliary surface portion 12a. However, this type of bending process can be easily performed by performing a valley fold on the auxiliary surface equivalent portion 13a and the extension portion 13c extending from the auxiliary surface equivalent portion 13a of the flat plate material 13, and bending the first to third auxiliary rail surface equivalent portions 13d, 13f, 13h. Moreover, in this case, since the second auxiliary rail surface portion 12f is provided with a wiring hole 12i that serves as a wiring path, when an electrical component is disposed in the space portion 6 as the external device 5, wiring becomes easy.

[0020] In the panel body 3 in which the first and second panels 9, 10 and the filler 8 are bonded together, an opening 9a is formed in a part of the first panel 9, and the auxiliary filler 8a at the opening 9a is removed to provide a groove-like space 6 with the inner surface of the second panel 10 as its bottom surface, the auxiliary member 12 is incorporated in a portion corresponding to the space 6 and is provided with an auxiliary panel 12a bonded to the inner surface of the second panel 10 and an auxiliary rail portion 12c interposed between the first and second panels 9, 10 to surround the periphery of the space 6, as follows: an auxiliary member disposing step of disposing an auxiliary member 12 having an auxiliary surface portion 12a and an auxiliary rail portion 12c on the inner surface of the second panel 10 in a portion corresponding to the space portion 6; An auxiliary filler disposing step of disposing an auxiliary filler 8a on the auxiliary surface portion 12a either before or after the step of disposing the auxiliary member 12. a bonding process for bonding the auxiliary surface portion 12a to the second surface plate 10, bonding the auxiliary rail portion 12c to the first and second surface plates 9 and 10, and bonding the auxiliary filling material 8a to the first surface plate 9 in conjunction with the process for pressing and bonding the filler material 8 to the first and second surface plates 9 and 10; a step of removing the opening-corresponding portion 9b of the first panel 9 where the space 6 is to be formed and the auxiliary filling material 8a after the bonding step; It may be assumed that the above exists. By doing this, when the panel body 3 having the space 6 is formed by press working, the press working is performed while the auxiliary member 12 with the auxiliary filler 8a disposed therein is incorporated, and when the opening-corresponding portion 9b of the first panel 9 is cut out, the auxiliary filler 8a can also be removed at the same time. As a result, not only is the removal of the auxiliary filler 8a easier and workability improved, but the auxiliary panel 12a can prevent the second panel 10 from absorbing moisture and deforming, and the peripheral portion of the space 6 of the first panel 9 can also be reinforced.

[0021] Of course, the present invention is not limited to the above-described embodiments, and there are cases in which the auxiliary member 12, such as the frame 7, the horizontal bars 11, and even the vertical bars not described in the above-described embodiments, can be used as auxiliary bar portions 12c. In such cases, the auxiliary bar portions 12c in the used portions may not be present. For example, as in the second embodiment shown in Figures 10(A) and (B) and the third embodiment shown in Figures 10(C) and (D), when the upper and lower horizontal bars 11 and the left and right vertical bars 15 can be used as auxiliary bar portions 12c, the auxiliary member 12 may simply have a pair of auxiliary bar portions 12c formed on the left and right or up and down. As an example of providing auxiliary rail portions 12c, when a space portion 6 is provided at the corner portion between a horizontal rail 11 and a vertical frame member 7, if the horizontal rail 11 and the frame member 7 are used both as rail portions, vertical and horizontal auxiliary rail portions 12c can be formed.Furthermore, when a space portion 6 is formed in an area surrounded on three sides by rails and frame members, if these can be used both as rail portions, it can be implemented as an auxiliary rail portion being formed in one place.

[0022] Furthermore, the auxiliary rail portion 12c does not have to be U-shaped as in the above-mentioned embodiments, but may be U-shaped as in the fourth embodiment shown in Fig. 11. In this embodiment, the auxiliary rail portion 12c is formed with a first auxiliary rail surface portion 12d bent from an edge portion 12b of the auxiliary surface portion 12a toward the first panel 9 side, a second auxiliary rail surface portion 12f bent from a tip portion 12e of the first auxiliary rail surface portion 12d toward the side opposite to the space portion 6, and a third auxiliary rail surface portion 12h bent from a tip portion 12g of the second auxiliary rail surface portion 12f toward the second panel 10 side. Incidentally, in this embodiment, a pair of auxiliary rail portions 12c are provided on the left and right sides, but it is of course not limited to this, and they may be provided around the entire four sides as in the first embodiment.

[0023] Furthermore, it is also possible to adopt the fifth, sixth and seventh embodiments shown in Figures 12(A), (B) and (C). In the fifth embodiment, the auxiliary rail portion 12c is not formed by bending the extension portion 13c of the flat plate material 13 as in the above embodiments, but rather the extension portion 13c of the flat plate material 13 consists only of the first auxiliary rail surface equivalent portion 13d, and a columnar (or hollow) auxiliary rail portion 13k made of, for example, wood or the like is bonded to the first auxiliary rail surface equivalent portion 13d. The present invention can also be implemented in this manner. In addition, in the sixth and seventh embodiments, the auxiliary rail portion 12c of the first and fourth embodiments is formed by bending and forming a fourth auxiliary rail surface portion 12k from the tip portion 12j of the third auxiliary rail surface portion 12h of the auxiliary rail portion 12c, thereby forming the auxiliary rail portion 12c into a square tube shape, which can also be implemented in this manner, and when done in this manner, the auxiliary rail portion 12c can be reinforced. Furthermore, the auxiliary member 12 may be formed by integrally forming the auxiliary surface portion 12a and the auxiliary rail portion 12c, for example, by molding a thermosetting resin. In addition, in the first embodiment, wiring hole 12i is provided in auxiliary surface portion 12a. However, in the first embodiment in which auxiliary rail portion 12c continues from space portion 6, auxiliary rail portion 12c can also be used as a wiring path for passing electrical wiring, and in this case, there is no need to form wiring hole 12i.
