Embodiments for Carrying Out the Invention

[0010] Hereinafter, a partition structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 is an external view showing an example in which a partition mechanism 100 having the partition structure of this embodiment is installed indoors. FIG. 2 is an external perspective view of the partition mechanism 100 shown in FIG. 1. FIG. 3 is a view of a part of the partition mechanism 100 shown in FIGS. 1 and 2 as seen from the inside of the partitioned space.

[0011] The partition mechanism 100 shown in FIG. 1 can partition the indoor space by being installed indoors. Here, the partition mechanism 100 shown in FIG. 1 partitions the interior together with a wall portion 111 including a hanging wall 101 suspended from a ceiling 120, but this is not the only case, and it may be partitioned only by the partition mechanism 100. The partition structure includes a position-fixed type partition structure in which a lower frame is fixed to the floor via a floor rail, and a sliding door type partition structure in the form of a movable partition that is not fixed to the floor and can be moved by the user.

[0012] In the following description, a three-dimensional coordinate system XYZ is defined with the floor surface 130 as the XY plane and the axis along the vertical direction with respect to the XY plane as the Z axis, and each component will be described using the three-dimensional coordinates of this XYZ system. The positive direction of the Z axis is the direction from the floor surface 130 toward the ceiling 120. Note that the three-dimensional coordinates of the XYZ system are also indicated in each figure.

[0013] As shown in FIG. 2, the partition mechanism 100 includes a plurality (six) of partition structures 1A to 1F having a surface along the XZ plane arranged in parallel in the X-axis direction, and a partition structure 1G (FIG. 2) having a surface along the YZ plane. Among these partition structures 1A to 1G, the position-fixed type partition structures are partition structures 1B to 1E and 1G, and the sliding door type partition structures as sliding doors are partition structures 1A and 1F. The sliding door type partition structures 1A and 1F open and close by advancing and retreating along the X axis. FIG. 3 shows the state in which the sliding door type partition structure 1A is open. Note that the partition mechanism 100 is not limited to these types, and the number of each type is also not limited to the exemplified number.

[0014] <1>Common configuration Regarding the partition structures 1A to 1G of both the fixed position type and the sliding door type, as shown in FIG. 2, it includes a panel member 2 erected in the positive Z-axis direction from the floor surface 130 (XY plane) side, and a frame member 4 (4') that holds the outer peripheral edge of the panel member 2. Also, a horizontal bar 6 is arranged at a height around the middle of each panel member 2. Here, each panel member 2 is not divided by the horizontal bar 6 in terms of the length of the Z-axis, but is a single-panel from the floor side to the ceiling side.

[0015] As an example, a glass plate can be used for the panel member 2. The panel member 2 is not limited to this, and a configuration that can be used for partitioning, such as a plastic panel, can be appropriately used. Note that the partition structures 1A to 1G may be constituted only by steel panels without a frame.

[0016] Both the frame member 4 and the horizontal bar 6 are configured by attaching a decorative material to the surface of the frame body of the skeleton. The frame body has a prismatic structure when viewed from the outside. Although the detailed structure will be described later, well-known building materials for partitioning can be used as the material constituting the frame body. As an example, an aluminum frame body can be used. As the decorative material, a wood-like decorative material is used as an example. The frame member 4 and the horizontal bar 6 with the wood-like decorative material attached can give the impression of being made of wood externally. As a specific example, a veneer is used. The veneer is formed by laminating an aluminum sheet on the back surface via an adhesive sheet or the like with the surface being a sheet of natural wood. For example, a veneer obtained by bonding an adhesive sheet with a thickness of 0.05 to 0.1 mm between a sheet of natural wood with a thickness of 0.2 mm and an aluminum sheet with a thickness of 0.2 mm can be used. Although it is such a relatively thin sheet, since the surface layer is natural wood, the frame member 4 and the horizontal bar 6 with the veneer attached to the frame body can give the impression of being a frame member made of wood externally, and can give people a sense of comfort by the texture, smell, and feel of the wood.

[0017] For the frame member 4, with respect to such a wood-like appearance, since the internal frame is made of building materials such as aluminum, it can exhibit incombustibility and fire resistance. For buildings such as buildings, there are various regulations in accordance with the Building Standards Law, and for the interior decoration of buildings, it is not possible to use combustible materials exceeding certain standards. Therefore, the regulations are also applied to the partition structure as part of the interior decoration, and it is difficult to manufacture the frame member 4 and the horizontal rail 6 from wood itself. Therefore, as in this embodiment, by attaching and covering a wood-grained decorative material (veneer) on the surface of the frame having an internal structure with incombustibility and fire resistance, the frame member 4 and the horizontal rail 6 that satisfy incombustibility and fire resistance while giving the appearance of wood are realized.

[0018] Note that it may be not only a veneer but also a decorative sheet or the like with a wood-like pattern printed on the surface. Also, not limited to a wood-like pattern, as long as it is a sheet-like decorative material that can extend over a plurality of surfaces of one frame body and can be attached to the frame body using an adhesive or the like, there is no particular limitation.

[0019] On the other hand, in the case of the mode of extending the decorative material and attaching it to the frame body in this way, due to the sheet rigidity of the decorative material, peeling may occur from the end of the decorative material. Especially in the case of a veneer, it has rigidity, and even when it is bent and attached along the corner of the frame body, it is likely to peel off from the attached end due to the restoring force. Assuming this peeling, it is conceivable to incorporate a decorative material of sufficient length into the frame body, but since organic solvent adhesives and paints are often used for the decorative material, considering fire resistance, it is necessary to keep the usage amount of the decorative material small. Therefore, it is desirable to use the decorative material only on the surface of the frame body.

[0020] In consideration of the above content, the partition structures 1A to 1G of the present embodiment extend the decorative material attached to the surface of the frame body to the surface of the frame body facing the panel holding member disposed on the surface of the panel member 2. In other words, the decorative material is bent from the surface of the frame member 4 facing the panel holding member and extends to the surface of the frame member 4 not facing the panel holding member. This configuration is applicable to any of the partition structures 1A to 1G shown in FIGS. 1 and 2. Hereinafter, the partition structure to which this configuration is applied will be described for each type.

[0021] <2>Position-fixed type partition structure As shown in FIG. 2, the position-fixed type partition structures 1B to 1E, 1G include a floor rail 3 provided on the floor surface 130 and a ceiling rail 5 provided on the ceiling 120 side (the lower end of the hanging wall 101 in FIG. 1). The floor rail 3 and the ceiling rail 5 each include a rail in the X-axis direction that is common to and configured in series for the partition structures 1B to 1E, and a rail in the Y-axis direction for the partition structure 1G. The rail in the X-axis direction and the rail in the Y-axis direction are connected.

[0022] The position-fixed type partition structures 1B to 1E, 1G include, as the panel member 2, four first to fourth panel members 2b to 2e arranged along the positive Z-axis direction and having front and back surfaces along the XZ plane (referred to as the panel member 2 when explaining the common configuration for any of them). Further, the frame member 4 includes a lower frame 41 laid along the floor rail 3, an upper frame 42 laid along the ceiling rail 5, and a vertical frame 43 disposed between the lower frame 41 and the upper frame 42.

[0023] Regarding the lower frame 41 and the upper frame 42, they are individually disposed corresponding to each panel member 2b to 2e, and are different from a series such as the floor rail 3 and the ceiling rail 5. Panel concave grooves for holding the panel member 2 are formed in each lower frame 41 and each upper frame 42. The lateral end portions of the panel member 2 can be fitted into the panel concave grooves of each lower frame 41 and each upper frame 42.

[0024] The vertical frame 43 is configured to be shared by two adjacent panel members 2 and to be arranged singly between them. In the vertical frame 43 arranged between the first panel member 2b and the second panel member 2c, a panel groove for holding the first panel member 2b is formed on the surface facing the negative X-axis direction, and a panel groove for holding the second panel member 2c is formed on the surface facing the positive X-axis direction. Also, in the vertical frame 43 arranged between the second panel member 2c and the third panel member 2d, a panel groove for holding the second panel member 2c is formed on the surface facing the negative X-axis direction, and a panel groove for holding the third panel member 2d is formed on the surface facing the positive X-axis direction. Further, in the vertical frame 43 arranged between the third panel member 2d and the fourth panel member 2e, a panel groove for holding the third panel member 2d is formed on the surface facing the negative X-axis direction, and a panel groove for holding the fourth panel member 2e is formed on the surface facing the positive X-axis direction. Here, on the surface facing the positive Y-axis direction of the vertical frame 43 between the second panel member 2c and the third panel member 2d, a panel groove for holding the fifth panel member 2g having front and back surfaces along the YZ plane is further provided. The vertical end portions of the panel member 2 can be fitted into the panel grooves of each vertical frame 43.

[0025] By arranging the vertical frame 43 provided with the panel grooves according to the arrangement of the panel members 2 in this way, the indoor space can be freely partitioned using a plurality of panel members 2.

[0026] Note that the partition structure of the position-fixed type may include only one panel member 2. In any of the lower frame 41, the upper frame 42, and the vertical frame 43 as described above, the decorative material is extended as described above.

[0027] <3>Sliding door type partition structure The sliding door type partition structures (sliding door structures) 1A and 1F shown in FIGS. 1 and 2 can be equipped with a well-known sliding mechanism. In this item, the partition structure 1A will be mainly described as an example, but the partition structure 1F can be configured in the same way. As shown in FIG. 3, when the partition structure 1A is in an open state, an opening is formed between the vertical frame 43' of the partition structure 1A and the door stop frame 431. The door stop frame 431 is provided so as to protrude from the frame (opening frame) 430 (FIG. 4) that forms the opening of the partition structure 1A. Then, by closing the vertical frame 43' of the partition structure 1A until it abuts against the door stop frame 431, the partition structure 1A can be set in a closed state.

[0028] The outer peripheral edge of the panel member 2a (sliding door) of the partition structure 1A is held by the frame member 4'. The frame member 4' includes a lower frame 41' laid along the floor surface 130, an upper frame 42' laid along the top rail 5', and two vertical frames 43' arranged between the lower frame 41' and the upper frame 42'. The vertical frame 43' and the lower frame 41' are connected by inserting the lower frame 41' into the notch formed at the lower end of the vertical frame 43'. The lower frame 41' inserted into the notch of the vertical frame 43' is connected and fixed to the vertical frame 43' by screwing. The connection part between the vertical frame 43' and the upper frame 42' is the same. On the surfaces of the frame member 4' and the frame 430, a decorative material is extended and attached in the same way as the frame member 4 of the position-fixed type partition structure. Note that the panel member 2a may be composed only of a steel panel without a frame member.

[0029] [Rail] The sliding door type partition structure 1A is configured to be slidable by a rail provided along the partition structure 1A. FIG. 4 is a cross-sectional view taken along the arrow in the cutting line C-C of FIG. 3, and shows a cross-sectional view of a portion centered on the rail provided along the sliding door type partition structure 1A. Note that FIG. 4 shows a view of the state where the vertical frame 43' of the partition structure 1A shown in FIG. 3 overlaps with the door stop frame 431 in the Y-axis direction as viewed from the negative X-axis side.

[0030] As shown in Fig. 4, the rail provided along the partition structure 1A is composed of a top rail 5', a fixed frame 30 extending along the top rail 5', a slide mechanism part 55 fixed to the top rail 5' via the fixed frame 30, and a rail cover 551 covering at least a part of the top rail 5'. The fixed frame 30 is height-adjustable with respect to the top rail 5' and has an adjustment function for horizontal installation.

[0031] As shown in Fig. 3, the top rail 5' is provided along the partition structure 1A. The top rail 5' provided with respect to the partition structure 1A includes an X-axis rail juxtaposed in the Y-axis direction with the position-fixed top rail 5 provided with respect to the position-fixed type partition structures 1B to 1E shown in Fig. 2. The X-axis rail included in the position-fixed top rail 5 provided with respect to the position-fixed type partition structures 1B to 1E extends to the position of the frame 430 in the X-axis direction. The top rail 5' and the top rail 5 are provided at the lower end of the hanging wall 101 shown in Fig. 2 on the ceiling 120 side shown in Fig. 1, but may be provided on the ceiling panel 121 provided on the ceiling 120 side.

[0032] The slide mechanism part 55 is fixed to the top rail 5' via the fixed frame 30. The slide mechanism part 55 includes a suspension fitting 550 that slides the upper frame 42' of the frame member 4' holding the panel member 2a along the top rail 5'. The suspension fitting 550 includes a lower end portion 550a connected to the upper frame 42' and an upper end portion 550b on the top rail 5' side. A part of the upper end portion 550b side of the suspension fitting 550 is covered by the top rail 5'. The partition structure 1A is slidable in the horizontal direction by sliding along the top rail 5' in a state of being suspended by the suspension fitting 550. The slide mechanism part 55 is composed of a rail body 55a extending along the fixed frame 30 and a suspension fitting 550 that slides along the rail body 55a. The rail body 55a is fastened from below to the fixed frame 30 with a fastener (not shown).

[0033] In FIG. 4, the top rail 5' is fixed to a reinforcing member 122 provided further above a ceiling panel 121 provided on the ceiling 120 side. Thereby, the strength of the sliding door type partition structure is ensured not only by the top rail 5' and the slide mechanism portion 55 but also by the reinforcing member 122, so that the degree of freedom in design of the lower side (indoor side) than the ceiling panel 121 is increased.

[0034] The frame 430 extends in the Z-axis direction of FIG. 4 from the floor surface 130 to the ceiling panel 121 side. The top rail 5 provided for the frame 430 is fixed to the ceiling panel 121 and is arranged parallel to the top rail 5' in the Y-axis direction.

[0035] The rail cover 551 is provided on the side surface of the top rail 5' facing the negative Y-axis direction so as to cover at least a part of the rail and the suspension fitting 550. The rail cover 551 is fixed to the fixed frame 30. The rail cover 551 functions as a frame body that covers the top rail 5', the slide mechanism portion 55, and the suspension fitting 550 further above the upper frame 42'.

[0036] On the lower surface side of the upper frame 42', a panel groove for fitting the panel member 2a is provided to open downward. On the surface of the upper frame 42', a decorative material is extended and attached. The decorative material extends along the upper surface, side surface, and lower surface of the upper frame 42' and further bends from the lower surface to the inner surface of the panel groove and extends. Also, a decorative material is extended and attached to the surface of the rail cover 511. By attaching the decorative material to the surfaces of the upper frame 42' and the rail cover 511, a more sophisticatedly designed sliding door type partition structure 1A can be provided.

[0037] Here, a shielding member 60 that covers at least a part of the suspension fitting 550 is provided between the rail and the panel member 2a. The shielding member 60 has two shielding members, a first shielding member 60a and a second shielding member 60b, provided with the panel member 2a interposed therebetween, but it may have only one of the shielding members. The suspension fitting 550 is covered by the two shielding members 60 from both sides in the Y-axis direction with the panel member 2a interposed therebetween.

[0038] A gap is generated between the rail and the panel member 2a, and the suspension fitting 550 can be visually recognized through this gap. In the partition structure 1A, since the gap between the rail and the panel member 2a is covered by the shielding member 60, the suspension fitting 550 can be hidden and the appearance can be improved without increasing the size of the frame body above the panel member 2a. Note that the shielding member 60 can hide the suspension fitting 550 and improve the appearance if it is provided at a position overlapping the rail and the panel member 2a when viewed from the Y direction.

[0039] The lower end of the second shielding member 60b is in contact with the upper end of the panel member 2a, and the upper end of the second shielding member 60b is in contact with the lower end of the rail. In the present embodiment, a gap is generated between the fixed frame 30 constituting the rail and the upper frame 42' that holds the upper part of the panel member 2a. The second shielding member 60b is provided such that its lower end abuts against the upper end of the upper frame 42' and its upper end abuts against the lower end of the fixed frame 30. Further, the second shielding member 60b is made of a sound insulating material. In this way, by filling the above-described gap with the sound insulating second shielding member 60b, the sound insulating property is enhanced. Note that the second shielding member 60b may be made of a light shielding material to enhance the light shielding property. Further, the second shielding member 60b may be made of a soft material to enhance the adhesion of the portion in contact with the rail and the panel member 2a.

[0040] Also, in this embodiment, a first light-blocking member 60a is provided in the gap formed between the rail cover 551 and the upper frame 42'. Thereby, the first light-blocking member 60a functions as a light blocker for this gap. Note that the first light-blocking member 60a may be a common part with the second light-blocking member 60b and may be made of a sound-insulating material. And by providing the first light-blocking member 60a so as to contact the lower end of the rail cover 551 and the upper end of the upper frame 42', the sound insulation performance may be further enhanced.

[0041] Here, the assembly mode of the suspension fitting 550 will be described with reference to FIG. 5. FIG. 5 is a diagram for explaining the assembly mode of the suspension fitting 550 that suspends the sliding door type partition structure 1A shown in FIG. 4. First, the connecting portion 552 is fixed to the ceiling panel 121 and the reinforcing member 122 by a plurality of screws 552a. The fixed frame 30 is connected to the connecting portion 552. Also, the rail cover 551 of the top rail 5' is connected to the connecting portion 552 and the fixed frame 30.

[0042] The fixed frame 30 has a surface facing the positive Z-axis direction, a surface facing the positive Y-axis direction, and a surface facing the negative Y-axis direction. The surface of the fixed frame 30 facing the positive Z-axis direction is fixed to the surface of the connecting portion 552 facing the positive Z-axis direction by a screw 30a. The surface of the fixed frame 30 facing the positive Y-axis direction is fixed to the surface of the connecting portion 552 facing the positive Y-axis direction by a screw 30b. Also, the surface of the fixed frame 30 facing the positive Y-axis direction is fixed to the upper frame 42 of the frame 430 by a screw 30c. Thereby, it is possible to assist in maintaining the horizontal state of the sliding door type partition structure 1A. As a result, it is possible to prevent malfunctions in the opening and closing operation due to the sliding door type partition structure 1A tilting in the horizontal direction.

[0043] Inside the fixed frame 30, the slide mechanism portion 55 is accommodated. In the suspension fitting 550 of the slide mechanism portion 55, the lower end portion 550a and the upper end portion 550b are removably connected. The suspension fitting 550 is assembled by connecting the upper end portion 550b accommodated in the fixed frame 30 and the lower end portion 550a of the suspension fitting 550 fixed to the upper frame 42' that holds the panel member 2a.

[0044] [Vertical frame 43'] Here, the installation mode of the sliding door type partition structure 1A will be described with reference to FIG. 6. FIG. 6 is a cross-sectional view taken along the arrow in the cutting line H-H of FIG. 3, and is a view showing an installation example of the sliding door type partition structure 1A. In the example shown in FIG. 6, the sliding door type partition structure 1A is provided adjacent to the position-fixed type partition structure 1B and the frame 430 in the X-axis direction.

[0045] As shown in FIG. 6, by sliding the partition structure 1A in the X-axis direction toward the partition structure 1B side, the partition structure 1A can be moved to a position where at least a part of the panel member 2a overlaps with the first panel member 2b in the Y-axis direction. Thereby, the partition structure 1A is in an open state. A handle 44 for gripping when sliding the partition structure 1A is provided on the vertical frame 43'.

[0046] Further, by sliding the partition structure 1A in the X-axis direction toward the door stop frame 431 provided so as to protrude from the frame 430, the vertical frame 43' is moved to the position indicated by the broken line, and the partition structure 1A can be moved to a position where the vertical frame 43' abuts against the door stop frame 431. Thereby, the partition structure 1A is in a closed state. In this way, the partition structure 1A can be opened and closed by sliding the partition structure 1A in the X-axis direction along the top rail 5'.

[0047] The vertical frame 43' on the door end side of the partition structure 1A has a contact portion 43'a. The contact portion 43'a is located at the tip of the vertical frame 43' on the door end side, which is one of the lateral ends of the panel member 2a. The contact portion 43'a abuts against the door stop frame 431 provided so as to protrude from the frame 430. In the door stop frame 431, a recess 431a for receiving the contact portion 43'a is provided at the position where the contact portion 43'a abuts. Further, in the recess 431a, a cushioning material 431b for reducing the impact and sound during door contact is provided on the surface that abuts against the contact portion 43'a.

[0048] In this way, an opening / closing partition structure is constituted by the sliding door type partition structure 1A, the frame 430 that forms the opening of the partition structure 1A, and the door stop frame 431 that is provided so as to protrude from the frame 430 and can abut against the partition structure 1A. Thereby, until the contact portion 43'a of the vertical frame 43' slides the partition structure 1A until it abuts against the door stop frame 431 provided outside the frame 430 that forms the opening, the sliding door can be closed. Thereby, it is possible to prevent pinching a hand between the frame 430 that forms the opening and the partition structure 1A when closing the partition structure 1A.

[0049] The vertical frame 43' on the door end side of the partition structure 1A has a door end portion 43'b. The door end portion 43'b is located at the rear end of the vertical frame 43' on the door end side, which is the other of the lateral end portions of the panel member 2a. And, on the door end portion 43'b of the vertical frame 43' on the door end side, a contact member 432 is provided that contacts the side facing the door stop frame 431 across the opening in the frame 430 that forms the opening when the contact portion 43'a contacts the door stop frame 431.

[0050] That is, when the contact portion 43'a contacts the door stop frame 431, the contact member 432 contacts the frame 430 to which the vertical frame 43 of the partition structure 1B adjacent to the partition structure 1A is fixed. Thereby, since the gap between the rear end of the vertical frame 43' on the door end side and the frame 430 on the adjacent partition structure 1B side is filled by the contact member 432, it is difficult to pinch a finger when opening and closing the partition structure 1A, and light shielding and sound insulation properties are obtained. The contact member 432 is constituted by a soft material as an example, and the light shielding and sound insulation properties are improved by closely adhering to the frame 430 on the adjacent partition structure 1B side.

[0051] Note that the abutting member 432 is configured to abut against the frame 430 on the side of the adjacent partition structure 1B only when the abutting portion 43’a abuts against the doorstop frame 431. The vertical frame 43’ of the partition structure 1B is provided at a position separated from the partition structure 1A by the amount of the abutting member 432 more than the frame 430 on the side of the partition structure 1B so as not to contact the abutting member 432 while sliding the partition structure 1A. Therefore, the abutting member 432 does not contact any member of the partition structure 1B while sliding the partition structure 1A, and abuts against the frame 430 when reaching the position of the frame 430 on the side of the partition structure 1B. Thereby, generation of noise due to friction between the abutting member 432 and other members can be suppressed while sliding the partition structure 1A.

[0052] Note that it may be configured to further include a position-fixed type partition structure at the position of the frame 430 on the doorstop frame 431 side shown in FIG. 6. That is, the sliding door type partition structure 1A may be provided adjacent to two position-fixed type partition structures in the X-axis direction. Thereby, the sliding door type partition structure 1A can be configured to open and close between the two position-fixed type partition structures.

[0053] [Lower frame 41’] FIG. 7 is a cross-sectional view taken along the line E-E in FIG. 3, showing a cross-section of a portion centered on the lower frame 41’ of the sliding door type partition structure 1A. A floor rail and an adjustment portion 433 are provided on the floor surface 130 side of the frame 430 that forms the opening of the partition structure 1A. The frame 430 is supported by the floor rail and the adjustment portion 433. The adjustment portion 433 adjusts the position of the frame 430 in the Z-axis direction, and the adjustment portion 433 cannot be visually recognized unless looking in from below the frame 430. Thereby, it can be made to appear as if the frame 430 is installed floating from the floor surface 130.

[0054] The lower frame 41' includes a frame body 420. The frame body 420 is configured in a hollow shape, and an accommodation portion 421 recessed in the positive Z-axis direction for accommodating the slide support portion 33 disposed on the floor surface 130 is provided inside thereof. The slide support portion 33 is fixed to the floor surface 130 by screws 33a. An adjustment portion 34 is provided above the slide support portion 33, and the position of the partition structure 1A in the Z-axis direction is adjusted. Since the adjustment portion 34 cannot be visually recognized unless looking into the lower side of the partition structure 1A, it can be made to appear as if the partition structure 1A is installed floating from the floor surface 130.

[0055] A light-shielding member 331 that covers at least a part thereof is provided between the lower end of the panel member 2a of the partition structure 1A and the floor surface 130. The light-shielding member 331 is provided so as to fill a gap generated between the partition structure 1A and the floor surface 130. Thereby, light-shielding property and sound-insulating property are obtained. In FIG. 7, the light-shielding member 331 is provided only on the frame 430 side, but the light-shielding member 331 may be provided on the opposite side across the slide support portion 33, or the light-shielding member 331 may be provided on both sides.

[0056] [Horizontal crossbar 6] The horizontal crossbar 6 shown in FIG. 2 is provided in each type of partition structure 1A to 1G. In the example shown in FIG. 2 and the like, the horizontal crossbar 6 is provided at one location for each partition structure 1A to 1G, but it may be provided at a plurality of locations. Further, in the present embodiment, a crossbar extending in the horizontal direction is exemplified, but it may be a crossbar (vertical crossbar) extending in the vertical direction (Z-axis direction), or a mode in which the crossbar member extends in an oblique direction with an inclination angle with respect to the horizontal or vertical direction, and the extending direction is not limited. In short, unlike the frame member that holds the outer peripheral edge of the panel member 2, as long as it is a structure for a crossbar having the same appearance as the frame member on the surface of the panel member 2, the configuration provided in the horizontal crossbar 6 can be applied.

[0057] The horizontal crossbar 6 is not configured to structurally divide the panel member 2 as described above. The horizontal crossbar 6 is affixed and secured to each of the front and back surfaces of the panel member 2. In short, the panel member 2 is a continuous single-panel extending from the end held by the lower frame 41 to the end held by the upper frame 42. Similar to the frame member 4 described above, the horizontal crossbar 6 has a configuration in which a decorative material is affixed to the surface of the skeletal frame member.
