[0007] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. As shown in Fig. 1, a panel body 1 has a frame body 2, a plurality of panels 3, horizontal bars 4, and vertical bars 5. The panel body 1 is installed in an openable and closable manner at an opening in a room, for example, as an interior door, and has a substantially rectangular shape.

[0008] The frame body 2 is arranged around the four periphery of the panel body 1 and forms the outer shape of the panel body 1. The frame body 2 is made of, for example, aluminum and is formed by a frame of a pair of horizontal members 21 and a pair of vertical members 22. The pair of horizontal members 21 extend in the left-right direction when viewed from the front of the panel body 1. The pair of horizontal members 21 includes an upper horizontal member 211 arranged at the upper end of the frame body 2 and a lower horizontal member 212 arranged at the lower end. The pair of vertical members 22 are arranged at both ends of the pair of horizontal members 21 in the left-right direction and extend in the up-down direction to connect the pair of horizontal members 21. As shown in FIGS. 2 and 3 , the pair of vertical members 22 and the pair of horizontal members 21 each have approximately U-shaped grooves 21a, 22a that open to the inner periphery of the frame body 2, and a panel 3 (described later) is inserted and fitted into the grooves 21a, 22a, respectively.

[0009] The multiple panels 3 are arranged inside the frame body 2, for example, three adjacent panels arranged vertically. The panels 3 include a first panel 31, a second panel 32, and a third panel 33. The first panel 31 to the third panel 33 are arranged vertically adjacent to each other with horizontal bars 4 (described later) interposed between them. The first panel 31 is a thin plate arranged at the uppermost position of the panel body 1. The first panel 31 is arranged by being fitted into the grooves 21a of the upper horizontal member 211 and the grooves 22a of the pair of vertical members 22. The third panel 33 is arranged at the lowermost position of the panel body 1. The third panel 33 is arranged by being fitted into the grooves 21a of the lower horizontal member 212 and the grooves 22a of the pair of vertical members 22. The second panel 32 is arranged between the first panel 31 and the third panel 33. The second panel 32 is a thin plate arranged by being fitted into the grooves 22a of the pair of vertical members 22. The panel 3 is made of, for example, resin. The first panel 31 to the third panel 33 are held by being sandwiched in the grating channel 34, with the grating channel 34 being disposed in the grooves 21a and 22a.

[0010] The horizontal crosspiece 4 is arranged inside the frame 2 to extend in the left-right direction and is fitted into the grooves 22a of the pair of vertical members 22. As shown in FIG. 2, the horizontal crosspiece 4 is formed in a generally rectangular cross section and has panel grooves 41a and 42a. The panel grooves 41a and 42a are formed as recesses at the widthwise center of the upper surface 41 of the horizontal crosspiece 4 and at the widthwise center of the lower surface 42 of the horizontal crosspiece 4, into which the panel 3 can be inserted along the direction in which the horizontal crosspiece 4 extends. Panel gaskets 43 that hold the panel 3 are disposed in the panel grooves 41a and 42a. As shown in FIG. 1, two horizontal crosspieces 4 are arranged inside the frame 2, and each horizontal crosspiece 4 includes an upper horizontal crosspiece 411 and a lower horizontal crosspiece 412. The upper horizontal crosspiece 411 is arranged between the first panel 31 and the second panel 32. The lower horizontal crosspiece 412 is arranged between the second panel 32 and the third panel 33.

[0011] 5, an engagement recess 44 is formed on the top surface 41 of the upper horizontal crosspiece 411, into which a vertical crosspiece 5 (described later) can be placed. The engagement recess 44 is arranged symmetrically on the front and back sides of the panel body 1, with the panel groove 41a sandwiched between them. The engagement recess 44 is formed in a roughly U-shape that opens to the center of the horizontal crosspiece 4 in cross section, i.e., on the panel groove 41a side, and is arranged facing one side and the other side with the panel groove 41a sandwiched between them.

[0012] Although not shown, an engagement recess 44 having the same shape as the engagement recess 44 shown in FIG. 5 is also formed on the underside of the lower horizontal crosspiece 412. The engagement recess 44 is formed at a position where the vertical crosspiece 5 engages, and is formed on either the upper or lower surface of the horizontal crosspiece 4. In other words, the engagement recess 44 is not a through-hole that penetrates from top to bottom, and when it is formed on the upper surface of the horizontal crosspiece 4, it is not formed on the lower surface. When it is formed on the lower surface of the horizontal crosspiece 4, it is not formed on the upper surface. In this embodiment, the engagement recess 44 is formed on the left side as shown in FIG. 1 on the upper surface of the upper horizontal crosspiece 411, on the right side as shown in FIG. 1 on the lower surface of the upper horizontal crosspiece 411, and on the left side as shown in FIG. 1 on the lower surface of the lower horizontal crosspiece 412.

[0013] The vertical bars 5 are arranged in the vertical direction inside the frame body 2, and as shown in FIG. 1 , for example, three are arranged discontinuously. The vertical bars 5 are attached to the surface of the panel 3 with double-sided tape 6 as an adhesive member. The vertical bars 5 extend in the vertical direction between the cross members 21 and the horizontal bars 4, and between the horizontal bars 4 themselves. Specifically, the vertical bars 5 include a first vertical bar 51 arranged on the surface of the first panel 31, a second vertical bar 52 arranged on the surface of the second panel 32, and a third vertical bar 53 arranged on the surface of the third panel 33. The second vertical bar 52 is arranged at a position offset in the left-right direction from the first vertical bar 51 and the third vertical bar 53.

[0014] As shown in Fig. 2, the first vertical beam 51 is connected by abutting its upper end, which is on one side in the vertical direction of the frame body 2, against the underside of the upper horizontal member 211. The first vertical beam 51 is connected to the upper horizontal beam 411 by inserting and engaging its lower end, which is on the other side in the vertical direction of the frame body 2, into an engaging recess 44 formed on the upper surface 41 of the upper horizontal beam 411. The upper end of the first vertical beam 51 serves as the abutting end 5a, and the lower end serves as the engaging end 5b.

[0015] The second vertical beam 52 is connected by inserting its upper end into and engaging with the engagement recess 44 formed on the underside of the upper horizontal beam 411. The second vertical beam 52 is connected by butting its lower end against the upper surface 41 of the lower horizontal beam 412. The upper end of the second vertical beam 52 becomes the engagement end 5b, and the lower end becomes the butting end 5a.

[0016] The third vertical beam 53 is connected by inserting its upper end into and engaging with the engagement recess 44 formed on the underside of the upper horizontal beam 411. The third vertical beam 53 is connected by butting its lower end against the upper surface 41 of the lower horizontal beam 412. The upper end of the third vertical beam 53 becomes the engagement end 5b, and the lower end becomes the butting end 5a.

[0017] In summary, the ends of the first vertical beam 51 and the third vertical beam 53 are connected to the upper horizontal member 211 and the lower horizontal member 212. When connecting the vertical beams 5 to the upper horizontal member 211 and the lower horizontal member 212, it is preferable to butt the ends together, as this eliminates the need to modify the shape of the horizontal member 21 by, for example, forming notches in the upper horizontal member 211 and the lower horizontal member 212, and is therefore more efficient in construction. In this case, an engaging recess 44 is formed on the horizontal beam 4 to allow for engagement. In the second vertical beam 52, both the upper and lower ends are connected to the horizontal beam 4. In this case, the weight of the second vertical beam 52 acts on the lower horizontal beam 412, strengthening the connection, so it is preferable to designate the lower end as the butting end 5a and the upper end as the engaging end 5b.

[0018] As shown in FIG. 3 , the vertical crosspiece 5 is made of hollow material that is approximately rectangular in cross section. The vertical crosspiece 5 has a front surface 54 that is the side visible when the panel body 1 is viewed from the front, a back surface 55 that faces the front surface 54, and a pair of side surfaces 56 that connect both left and right ends of the front surface 54 and the back surface 55. The back surface 55 is the surface that is attached to the panel 3, and has a recess 57 in which double-sided tape 6 is placed. Specifically, the recess 57 is recessed toward the front surface 54 from a position slightly toward the center from both ends of the back surface 55 in the width direction, and has a flat bottom 571 on the surface facing the front surface 54. The vertical crosspiece 5 is attached to the panel 3 with the double-sided tape 6 placed in the recess 57.

[0019] The method of assembling the panel body 1 will now be described. First, the grating channel 34 and panel packing 43 are attached in predetermined positions to the periphery of each of the first panel 31, second panel 32, and third panel 33. The panel packing 43 is attached in sections midway in the left-right direction of the panel 3, leaving open positions where the vertical beams 5 will be placed later. Meanwhile, the upper horizontal member 211, lower horizontal member 212, upper horizontal beam 411, and lower horizontal beam 412 are inserted into the grooves 22a of the vertical members 22 on one side in the left-right direction. Then, the first panel 31 to the third panel 33, to which the grating channel 34 and panel packing 43 are attached, are prepared, and while taking care to match the position where the panel packing 43 is divided with the position where the vertical beams 5 will be arranged later, the first panel 31 is inserted between the upper horizontal member 211 and the upper horizontal beam 411, the second panel 32 between the upper horizontal beam 411 and the lower horizontal beam 412, and the third panel 33 between the lower horizontal beam 412 and the lower horizontal member 212. Next, these horizontal members 21 and horizontal beams 4 are attached by inserting them into the grooves 22a of the vertical members 22 on the other side.

[0020] Furthermore, necessary parts depending on the intended use are attached to the frame body 2. For example, if the panel body 1 is to be used as an interior door, a hoist case, an upper end cap, etc. are attached.

[0021] Thereafter, double-sided tape 6 is attached to the recess 57 formed on the back surface 55 of the vertical crosspiece 5. Then, the release paper on the opposite side of the double-sided tape attached to the back surface 55 is peeled off, and the engaging end 5b of the vertical crosspiece 5 is inserted into the engaging recess 44. The vertical crosspiece 5 with the double-sided tape 6 attached is attached to the panel 3 so as to align with the panel 3, and the abutting end 5a is positioned against the horizontal crosspiece 4 or horizontal member 21.

[0022] This embodiment provides the following advantages. The panel body 1 includes a frame body 2 formed by a pair of vertical members 22 and a pair of horizontal members 21, a panel 3 disposed inside the frame body 2, horizontal beams 4 disposed inside the frame body 2 so as to extend in the left-right direction, and vertical beams 5 disposed inside the frame body 2 so as to extend in the up-down direction. Each vertical beam 5 includes an abutting end 5a that abuts against and connects to the horizontal beam 4 or the horizontal member 21 on one side in the up-down direction, and an engaging end 5b that engages with and connects to an engaging recess 44 formed in the horizontal beam 4 on the other side in the up-down direction. Because one end of the vertical beam 5 is abutted against the horizontal beam 4 and the other end is positioned so as to engage with the engaging recess 44, it is not necessary to insert all of the vertical beams 5 into the horizontal beams 4, improving workability. The arrangement of the vertical beams 5 extending upward and the vertical beams 5 extending downward for a single horizontal beam 4 can be freely designed, improving design freedom.

[0023] According to this embodiment, the horizontal crosspiece 4 is configured to include panel grooves 41a, 42a formed on the upper surface 41 and the lower surface 42 along the direction in which the horizontal crosspiece 4 extends, into which the panel 3 can be inserted. The engagement recesses 44 are arranged symmetrically on the front and back sides, sandwiching the panel grooves 41a, 42a. By forming the engagement recesses 44, the vertical crosspiece 5 can be positioned and stably attached to the horizontal crosspiece 4 without having to be inserted into the horizontal crosspiece 4. Furthermore, because the engagement recesses 44 are arranged symmetrically on both sides of the panel grooves 41a, 42a, misalignment between the front and back sides can be prevented when the vertical crosspiece 5 is placed on the front and back sides via the panel 3.

[0024] According to this embodiment, the vertical crosspiece 5 includes a recess 57 where the surface that is attached to the panel 3 is recessed toward the front side, and double-sided tape 6 is placed in the recess 57. Since the vertical crosspiece 5 can be attached by adhesion, installation is easy. Furthermore, by placing the double-sided tape 6 in the recess 57, the position where the double-sided tape 6 is attached can be determined. This prevents the double-sided tape 6 from shifting from the vertical crosspiece 5 and prevents the vertical crosspiece 5 from shifting position due to excess adhesive, improving installation efficiency.

[0025] The present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope of achieving the object of the present disclosure are included in the present disclosure. In the above-described embodiments, an example of a panel body 1 in which resin panels are arranged on an aluminum frame body 2 has been described. An example in which three panels 3, two horizontal bars 4, and three vertical bars 5 have been arranged has been described. However, the number, arrangement, and materials of the panels 3, horizontal bars 4, and vertical bars 5 are not limited. For example, the frame body or some of the multiple panels may be made of wood or medium-density fiberboard, and vertical bars may be arranged on a resin panel arranged as a lighting section in part of the panel body.

[0026] Although the double-sided tape 6 has been used as an example of the adhesive member, the adhesive member is not limited to this. A liquid or semi-solid adhesive may also be applied. [Explanation of symbols]
