Description

[Technical Field]

[0001] The present invention relates to the technical field of double-panel partitions for dividing interior spaces. [Background technology]

[0002] Nowadays, partitions made up of panels are sometimes used to divide indoor spaces. Some of these partitions are configured to divide the indoor space into corners, with first and second panel bodies having different surface directions, and the leading ends of these first and second panel bodies connected to each other in an L-shape via a corner. In partitions with this configuration, a conventional configuration has been known in which the leading ends of the first and second panel bodies are butted together and connected with a sealing material at the corner (see, for example, Figure 5 of Patent Document 1). However, with this configuration, the leading end face of one panel body is exposed on the protruding corner of the corner, requiring advanced finishing work on the exposed leading end face of the panel body, resulting in poor production efficiency. Therefore, in the structure of Patent Document 1, when connecting the first and second panel bodies at the corner portion, a corner joint member is used which has fitting grooves into which the tip end edges of the first and second panel bodies respectively fit. By using this corner joint member, it is possible to prevent the tip end faces of the panel bodies from being exposed on the protruding corner side of the corner portion. However, because this structure requires male and female fitting of the inner and outer corner joint portions, there is a problem in that the structure is complex and the number of parts is large. Meanwhile, attempts have been made to make the panel bodies that make up partitions double-panel (multi-layer panel) structures consisting of a pair of inner and outer panels that face each other at a specified distance in order to improve sound insulation, heat insulation, etc. In such double-panel structures, when the leading ends of first and second panel bodies with different surface directions are connected in an L shape, the leading ends of the outer panels of the first and second panel bodies and the leading ends of the inner panels of the first and second panel bodies are connected in an L shape at the outside corner and the inside corner, respectively (see, for example, Patent Document 2).

[0003] [Patent Document 1] Patent No. 4552195 [Patent Document 2] Japanese Patent Application Laid-Open No. 2007-23481 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the double panel type is configured so that the upper and lower edge portions of the panel body are directly fitted into the panel fitting grooves, so if the panel body or the fitting grooves vibrate abnormally, the load from the vibration acts directly on the panel body, making the panel body prone to cracking, and these are the issues that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention has been made in view of the above-mentioned circumstances and with the aim of solving these problems, and the invention of claim 1 relates to a double-panel partition comprising first and second panel bodies with different surface directions for dividing an interior space into a corner, the first and second panel bodies being a pair of inner and outer panels opposed to each other with a predetermined gap between them, and at least one of the upper and lower edge portions of the outer and inner first and second panel bodies being fitted into an outer panel fitting groove and an inner panel fitting groove formed in a frame provided on a body side member, the outer panel fitting grooves and the inner panel fitting grooves being connected in an L-shape at the protruding corners and the recessed corners, and the tip ends of the first and second panel bodies of the outer panel and the tip ends of the first and second panel bodies of the inner panel being connected together at the protruding corners and the recessed corners of the outer and inner panel fitting grooves This double-panel partition is characterized in that, in creating a continuous L-shaped configuration, bead materials that are attached to the groove side surfaces of the outer and inner panel fitting grooves on the opposing sides, and that provide elastic support for the outer and inner panels fitted into the outer and inner panel fitting grooves, are made continuous by having the tip edges of the bead materials abut against each other in an L-shape at the corners of the outside and inside corners of the outer and inside panel fitting grooves, while clamp materials that are fitted and incorporated between the groove side surfaces on the opposite sides of the outer and inner panel fitting grooves facing each other and the panel surfaces of the inner and outer panels fitted into each fitting groove, and that provide elastic support for the outer and inner panels fitted into each fitting groove, are made continuous by having the tip edges of the clamp materials abut against each other in an L-shape at the corners of the outside and inside corners of the outer and inner panel fitting grooves. The invention of claim 2 is a double-panel partition as described in claim 1, characterized in that an outer corner joint member shaped like a square pillar or square tube is incorporated into the protruding corner portion of the outer panel fitting groove, the first and second panel bodies of the outer panel are connected at the protruding corner portion via the outer corner joint member by the leading edges of the first and second panel bodies abutting against the surface of the outer corner joint member, the leading edges of the bead material attached to the outer panel fitting groove are connected by abutting in an L-shape while facing the inner corner portion of the outer corner joint member, and the leading edges of the clamping material fitted and fitted between the outer panel fitting groove and the outer panel are fitted between the outer corner joint member and the side surface of the groove and are connected by abutting in an L-shape beyond the outer corner portion of the outer corner joint member. The invention of claim 3 is a double-panel partition as described in claim 2, characterized in that a chamfered portion is formed at the inner corner portion where the tip edges of the bead material of the outer corner joint members face each other, and one of the tip edges of the bead material abuts against the chamfered portion. The invention of claim 4 is a double-panel partition as described in claim 1, characterized in that the connection between the first and second panel bodies of the inner panel at the inside corner portion is made by fitting one of the first and second panel bodies into the inner panel fitting groove at the inside corner portion and the other panel body abutting against the fitted panel body, the leading edges of the bead material attached to the inner panel fitting groove are continuous by abutting in an L-shape at a portion beyond the leading edge of the panel body fitted into the inside corner portion of the inner panel fitting groove, and the leading edges of the clamping material fitted and assembled between the inner panel fitting groove and the inner panel are continuous by abutting in an L-shape at the portion where the other panel body abuts against the fitted panel body. The invention of claim 5 is a double-panel partition as described in claim 1, characterized in that an inner corner joint member shaped like a square pillar or square tube is incorporated into the inside corner portion of the fitting groove for the inner panel, the first and second panel bodies of the inner panel are connected at the inside corner portion via the inner corner joint member by the leading edges of the first and second panel bodies abutting against the surface of the inner corner joint member, the leading edges of the bead material attached to the fitting groove for the inner panel are continuous by abutting in an L-shape at a location beyond the outer corner portion of the inner corner joint member, and the leading edges of the clamping material fitted and incorporated between the fitting groove for the inner panel and the inner panel are continuous by abutting in an L-shape while facing the inside corner portion of the inner corner joint member. The invention of claim 6 is a double-panel partition as described in claim 5, characterized in that when the inner panel is so thin that the bead material cannot be inserted between the inner corner joint member and the groove side surface, the tip edge of the bead material abuts against the surface of the inner corner joint member that abuts against the panel body, and a gap material is inserted and incorporated into the gap between the inner corner joint member and the groove side surface. [Effects of the Invention]

[0006] By adopting the invention of claim 1, in a double-panel partition, the bead materials for elastically supporting the outer and inner panels are connected to each other on the groove side surfaces on the sides where the outer and inner panels of the fitting grooves for the outer and inner panels face each other, with the tip edges of the bead materials abutting in an L-shape against the protruding corners and recessed corners of the fitting grooves for the outer and inner panels, and also, on the groove side surfaces on the opposite side from where the outer and inner panels face each other, the clamp materials for elastically supporting the outer and inner panels fitted into each fitting groove are connected to each other, with the tip edges of the clamp materials abutting in an L-shape against the protruding corners and recessed corners of the fitting grooves for the outer and inner panels.As a result, the inner and outer panels are elastically supported by the bead materials and clamp materials on both sides in relation to the panel fitting grooves and are protected from abnormal vibrations, and further, the bead materials and clamp materials are arranged in a continuous state at each corner, eliminating any unnatural appearance. With the invention of claim 2, an outer corner joint member shaped like a square pillar or square cylinder is incorporated into the protruding corner of the outer panel fitting groove, and the first and second panel bodies of the outer panel are connected at the protruding corner via the outer corner joint member when the leading edges of the first and second panel bodies abut against the surface of the outer corner joint member. The leading edges of the bead materials attached to the outer panel fitting groove abut against the inner corner of the outer corner joint member in an L-shape, and the leading edges of the clamp materials fitted into the outer panel fitting groove and the outer panel are fitted between the outer corner joint member and the groove side surface, and abut in an L-shape beyond the outer corner of the outer corner joint member, resulting in a natural connection between the bead materials and the clamp materials, even though an outer corner joint member is used to connect the protruding corner. By adopting the invention of claim 3, the leading edge of one of the bead materials of the outer corner joint member comes into contact with the chamfered portion formed at the inner corner where the leading edges of the bead material of the outer corner joint member face each other. As a result, the contact of the bead material with the outer corner joint member becomes more stable than when the bead material comes into contact with the corner when there is no chamfered portion, which contributes to the stabilization of the structure. By adopting the invention of claim 4, the connection between the first and second panel bodies of the inner panel at the inside corner portion is such that one of the first and second panel bodies is fitted into the inner panel fitting groove at the inside corner portion and the other panel body abuts against the fitted panel body, and the leading edge portions of the bead materials attached to the inner panel fitting groove abut in an L-shape at a location beyond the leading edge of the panel body fitted into the inside corner portion of the inner panel fitting groove, and the leading edge portions of the clamping materials fitted and incorporated between the inner panel fitting groove and the inner panel abut in an L-shape at the location where the fitted panel body abuts against the other panel body, thereby becoming continuous.As a result, there is no unnatural connection between the bead materials and the clamping materials even at the inside corner portion. According to the invention of claim 5, when an inner corner joint member shaped like a square pillar or square cylinder is incorporated into the inside corner of the inner panel fitting groove, the tip edges of the first and second panel bodies of the inner panel are connected at the inside corner via the inner corner joint member as they abut against the surface of the inner corner joint member, and the tip edges of the bead materials attached to the inner panel fitting groove abut in an L-shape beyond the outer corner of the inner corner joint member, and the tip edges of the clamp materials fitted between the inner panel fitting groove and the inner panel abut in an L-shape as they face the inside corner of the inner corner joint member. As a result, even though an inner corner joint member is used to connect the inside corner, there is no unnatural connection between the bead materials and the clamp materials. By adopting the invention of claim 6, even if the inner panel becomes too thin at the inside corner portion and the bead material becomes too thick to fit between the inner corner joint member and the groove side surface, the tip edge of the bead material abuts against the surface of the inner corner joint member that abuts against the panel body, and a gap material is inserted into the gap between the inner corner joint member and the groove side surface, so that the gap is closed and the inner corner joint member can be installed without any play.

In this embodiment, for the sake of convenience, the viewing direction of the first and second panel bodies 2 and 3 is referred to as the "left-right direction" (in this embodiment, the left-right direction of the first panel body 2 and the left-right direction of the second panel body 3 are perpendicular to each other), the viewing direction of the first and second panel bodies 2 and 3 is referred to as the "inside-outside direction", and the inside side of the room R separated by the partition 1 is referred to as the "inside" and the outside side of the room R is referred to as the "outside". Furthermore, of the left and right edge portions of the first and second panel bodies 2, 3, the side that is connected at the protruding corner portion 6 and the recessed corner portion 7 will be referred to as the "tip side (tip side in the left-right direction)", and the opposite connection side will be referred to as the "base side (base side in the left-right direction)". In addition, the side where the outer panel 4 and the inner panel 5 face each other will be referred to as the "panel facing side (or facing side)" and the opposite side will be referred to as the "anti-panel facing side (or opposite side)", but it goes without saying that the present invention is not limited to such convenient definitions.

A bead material 14 that abuts and elastically supports the opposing panel surfaces 4a, 5a of the outer panel 4 and the inner panel 5 fitted into the outer-panel fitting groove 11a and the inner-panel fitting groove 11b is attached to the panel-facing groove side surface 11d before the outer panel 4 and the inner panel 5 are fitted. Furthermore, a retainer 15 that abuts against and elastically supports the opposite panel surfaces 4b, 5b of the outer panel 4 and the inner panel 5 that are fitted into the outer panel fitting groove 11a and the inner panel fitting groove 11b is attached to the side gutter side 11e opposite to the panels after the outer panel 4 and the inner panel 5 are fitted in. In this embodiment, the outer panels 4 and the inner panels 5 that are adjacent to each other on the left and right and flush with each other are connected via a joint material 19 such as double-sided adhesive tape or adhesive.

[0011] Meanwhile, the upper frame 12 is provided with outer-panel fitting grooves 12a and inner-panel fitting grooves 12b, into which the upper ends of the outer panel 4 and the inner panel 5 are fitted, respectively, and are formed symmetrically and spaced apart. The outer-panel fitting grooves 12a and inner-panel fitting grooves 12b are recessed grooves that are open at the bottom and each include a groove bottom surface 12c, a panel-facing groove side surface 12d, and an opposite-panel facing groove side surface 12e. As with the vertical frame 11, a bead material 14 is attached to the panel-facing groove side surface 12d in advance, prior to fitting the outer panel 4 and the inner panel 5, to abut and elastically support the opposing panel surfaces 4a and 5a of the outer panel 4 and the inner panel 5 fitted into the outer-panel fitting groove 12a and the inner-panel fitting groove 12b. In addition, a retaining member 15 that abuts against and elastically supports the opposite panel surfaces 4b, 5b of the outer panel 4 and inner panel 5 that are inserted into the outer panel fitting groove 12a and inner panel fitting groove 12b is attached to the side gutter side 12e opposite the panels after the outer panel 4 and inner panel 5 are inserted. The upper frame body 12 is configured so that the portion supporting the first panel body 2 and the portion supporting the second panel body 3 are connected in an L-shape, and the outer panel fitting grooves 12a and inner panel fitting grooves 12b, into which the outer panels 4 and inner panels 5 of the first and second panel bodies 2 and 3 are fitted, are formed so as to be continuous in an L-shape at the protruding corner portion 6 and the recessed corner portion 7. In the following description, as necessary, the outer panel 4 of the first panel body 2 will be referred to as the first outer panel 4A, the inner panel 5 of the first panel body 2 will be referred to as the first inner panel 5A, the outer panel fitting groove 12a into which the first outer panel 4A is fitted will be referred to as the first outer panel fitting groove 12aA, the inner panel fitting groove 12b into which the first inner panel 5A is fitted will be referred to as the first inner panel fitting groove 12bA, and the first outer panel fitting groove 12aA and the first inner panel fitting groove 12bA will be referred to as the first inner panel fitting groove 12bA. The panel-facing groove side surface 12d and the anti-panel-facing groove side surface 12e that form the first outer panel are referred to as the first panel-facing groove side surface 12dA, the first anti-panel-facing groove side surface 12eA, the bead material 14 attached to the first outer-panel fitting groove 12aA and the first inner-panel fitting groove 12bA are referred to as the first bead material 14A, and the pressing material 15 attached to the first outer-panel fitting groove 12aA and the first inner-panel fitting groove 12bA are referred to as the first pressing material 15A. Furthermore, the leading end surface 4c of the first outer panel 4A (the end surface that is connected at the external corner portion 6) is referred to as 4Ac, and the leading end surface 5c of the first inner panel 5A (the end surface that is connected at the internal corner portion 7) is referred to as 5Ac. Furthermore, the outer panel 4 of the second panel body 3 will be referred to as the second outer panel 4B, the inner panel 5 of the second panel body 3 will be referred to as the second inner panel 5B, the outer panel fitting groove 12a into which the second outer panel 4B is fitted will be referred to as the second outer panel fitting groove 12aB, the inner panel fitting groove 12b into which the second inner panel 5B is fitted will be referred to as the second inner panel fitting groove 12bB, the panel-facing groove side surface 12d and the anti-panel-facing groove side surface 12e that form the second outer panel fitting groove 12aB and the second inner panel fitting groove 12bB will be referred to as the second panel-facing groove side surface 12dB and the second anti-panel-facing groove side surface 12eB, the bead material 14 attached to the second outer panel fitting groove 12aB and the second inner panel fitting groove 12bB will be referred to as the second bead material 14B, and the clamping member 15 attached to the second outer panel fitting groove 12aB and the second inner panel fitting groove 12bB will be referred to as the second clamping member 15B. Furthermore, the tip end surface 4c of the second outer panel 4B is denoted by 4Bc, and the tip end surface 5c of the second inner panel 5B is denoted by 5Bc.

[0012] The lower frame 13 is constructed using a frame main body 16 attached to the lower rail member 10 and a pair of inner and outer push edges 17 assembled to the frame main body 16. Outer panel fitting grooves 13a and inner panel fitting grooves 13b, into which the lower ends of the outer panel 4 and the inner panel 5 are respectively fitted and assembled, are formed symmetrically on the outside and inside with a gap between them by the frame main body 16 and the push edges 17. The outer panel fitting grooves 13a and inner panel fitting grooves 13b are recessed grooves that are open at the top and each have a groove bottom surface 13c, a panel-facing groove side surface 13d, and an opposite-panel facing groove side surface 13e. As with the vertical frame body 11 and upper frame body 12 described above, a bead material 14 that abuts against and elastically supports the opposing panel surfaces 4a, 5a of the outer panel 4 and the inner panel 5 that are fitted into the outer panel fitting groove 13a and the inner panel fitting groove 13b is attached to the panel-facing side groove side 13d in advance, before the outer panel 4 and the inner panel 5 are fitted in. In addition, a pressing material 15 that abuts against and elastically supports the opposite panel surfaces 4b, 5b of the outer panel 4 and the inner panel 5 that are fitted into the outer panel fitting groove 13a and the inner panel fitting groove 13b is attached to the panel-opposite side groove side 13e after the outer panel 4 and the inner panel 5 are fitted in. In the lower frame body 13, the groove bottom surface 13c and the panel-facing groove side surface 13d that constitute the outer-panel fitting groove 13a and the inner-panel fitting groove 13b are provided on the frame main body 16, and the non-panel-facing groove side surface 13e is provided on the push edge 17. Also, the frame main body 16 is provided with a locking receiving portion 16a below the groove bottom surface 13c that locks with a locking portion 17a formed on the push edge 17, and the outer-panel fitting groove 13a and the inner-panel fitting groove 13b are formed by engaging the locking portion 17a with the locking receiving portion 16a of the frame main body 16 and assembling the push edge 17 to the frame main body 16, but the assembling of the push edge 17 to the frame main body 16 is performed after the lower ends of the outer panel 4 and the inner panel 5 are placed on the groove bottom surface 13c via setting blocks 18. Like the upper frame body 12, the lower frame body 13 is also configured so that the portion supporting the first panel body 2 and the portion supporting the second panel body 3 are connected in an L shape, and the outer panel fitting grooves 13a and inner panel fitting grooves 13b, into which the outer panels 4 and inner panels 5 of the first and second panel bodies 2 and 3 are fitted, are formed so as to be continuous in an L shape at the protruding corner portion 6 and the recessed corner portion 7.

[0013] Next, the connection between the outer panels 4 of the first and second panel bodies 2, 3 at the projected corner portion 6 will be described. Reference numeral 20 denotes a corner joint member disposed at the protruding corner portion 6. (The corner joint member may be opaque, but can also be made of a resin material such as translucent or transparent acrylic resin.) The corner joint member 20 has a vertically oriented rectangular tubular shape, and its upper and lower ends are fitted into the corners of the protruding corner portion 6 of the outer panel fitting grooves 12a, 13a of the upper frame body 12 and the lower frame body 13. The first outer panel 4A and the second outer panel 4B are connected via the corner joint member 20. In this case, the protruding corner portion 6 of the upper frame body 12 and the protruding corner portion 6 of the lower frame body 13 are similar, so the protruding corner portion 6 of the upper frame body 12 will be illustrated in FIG. 5 for explanation. It should be noted that the corner joint member 20 may, of course, be a solid rectangular prism rather than a hollow rectangular tubular shape. The corner joint member 20 has first to fourth side surface portions 20a to 20d that are continuous around the periphery and form a rectangular cylindrical shape, and a chamfered portion 20e is formed between the third side surface portion 20c and the fourth side surface portion 20d. The corner joint member 20 is disposed in the projected corner portion 6 of the outer-panel fitting groove 12a with the first side surface portion 20a facing the left-right leading edge of the first anti-panel facing side groove side surface 12eA, the second side surface portion 20b facing the left-right leading edge of the second anti-panel facing side groove side surface 12eB, the third side surface portion 20c crossing the second outer-panel fitting groove 12aB in the groove width direction, and the fourth side surface portion 20d crossing the first outer-panel fitting groove 12aA in the groove width direction, and the leading edge of the first bead material 14A or the second bead material 14B abutting against the chamfered portion 20e. The tip end face 4Ac of the first outer panel 4A is abutted against the fourth side surface portion 20d of the corner joint member 20 arranged in the protruding corner portion 6 and connected and fixed with a joint material (double-sided adhesive tape, adhesive, etc.) 19, and the tip end face 4Bc of the second outer panel 4B is abutted against the third side surface portion 20c and connected and fixed with the joint material 19, so that the first outer panel 4A and the second outer panel 4B are connected in an L shape via the corner joint member 20. After the first and second outer panels 4A and 4B are connected to the corner joint member 20, the first and second side surfaces 20a and 20b of the corner joint member 20 are supported by the first and second retaining members 15A and 15B attached to the first and second non-panel-facing side surfaces 12eA and 12eB. The leading end of the first bead material 14A or the second bead material 14B abuts against the chamfered portion 20e and is supported by the corresponding bead material 14. Thus, the corner joint member 20 is supported and positioned from three sides: the first and second side surfaces 20a and 20b and the chamfered portion 20e. In this case, the leading end of the first bead material 14A or the second bead material 14B abuts against the chamfered portion 20e in a surface-to-surface contact state, resulting in a stable abutment, rather than the unstable abutment state that would occur if the chamfered portion 20e were not present and the corners were abutting against each other. The third and fourth side surface portions 20c, 20d correspond to the one-side connecting surface portion and the other-side connecting surface portion of the corner joint member of the present invention.

[0014] Meanwhile, the connection between the inner panels 5 of the first and second panel bodies 2, 3 at the inside corner portion 7 does not have a corner joint member 20 like the protruding corner portion 6, but is configured so that the leading edge portions of the first inner panel 5A and the second inner panel 5B are butted against each other in an L-shape to be connected, and the connection between the inner panels 5 at the inside corner portion 7 will be described below. In this case, just like the protruding corner portion 6, the inside corner portion 7 of the upper frame body 12 and the inside corner portion 7 of the lower frame body 13 are similar, so the inside corner portion 7 of the upper frame body 12 will be described using the illustration in Figure 5 above. At the inside corner portion 7, the first and second bead materials 14A, 14B are arranged so that the leading end of the first bead material 14A attached to the first-panel-facing groove side surface 12dA abuts against the second-panel-facing groove side surface 12dB, and the leading end of the second bead material 14B attached to the second-panel-facing groove side surface 12dB abuts against the leading end of the first bead material 14A. By arranging the first and second bead materials 14A, 14B in this manner, an extension portion 14a is formed at the leading end of the first bead material 14A against which the leading end face of the second inner panel 5B fitted in the second inner-panel fitting groove 12bB can abut. The tip end face 5Bc of the second inner panel 5B is abutted against the extended portion 14a of the first bead material 14A, and the tip end face 5Ac of the first inner panel 5A, which is recessed into the fitting groove 12bA for the first inner panel, is abutted against the panel surface 5Bb on the opposite side of the tip side of the second inner panel 5B that is abutted against the extended portion 14a, and they are connected and fixed with a joint material 19, so that the tip ends of the first inner panel 5A and the second inner panel 5B are connected to each other in an L shape. By connecting the first inner panel 5A and the second inner panel 5B in this manner, the opposing panel surface 5Aa of the first inner panel 5A and the leading end surface 5Bc of the second inner panel 5B both come into contact with the first bead material 14A, so that the opposing panel surface 5Aa of the first inner panel 5A and the leading end surface 5Bc of the second inner panel 5B can be arranged to be flush with high precision without any additional alignment. In this case, the leading end surface 5Bc of the second inner panel 5B is exposed on the outside corner side of the inside corner portion 7, but because the outside corner side of the inside corner portion 7 is between the outer panel 4 and the inner panel 5, finishing is not required on the leading end surface 5Bc of the second inner panel 5B even though it is exposed.

[0015] In the present embodiment configured as described above, the partition 1 comprises first and second panel bodies 2, 3 with different surface directions to divide the interior space into a corner shape, and these first and second panel bodies 2, 3 are of a double-panel type configured using a pair of outer panel 4 and inner panel 5 facing each other at a predetermined distance, and the leading ends of the outer panels 4 of the first and second panel bodies 2, 3 and the leading ends of the inner panels 5 of the first and second panel bodies 2, 3 are connected in an L-shape at the outside corner portion 6 and the inside corner portion 7, respectively. The outside corner portion 6 is connected using a corner joint member 20 having connecting portions (in this embodiment, the third side surface portion 20c and the fourth side surface portion 20d) to which the leading end surfaces of the outer panels 4 of the first and second panel bodies 2, 3 are connected, while the inside corner portion 7 is connected and fixed by butting the leading end edges of the inner panels 5 of the first and second panel bodies 2, 3 against each other in an L-shape.

[0016] As a result, at the inside corner portion 7, the inside panels 5 are connected simply by butting the leading edge portions of the inside panels 5 together in an L-shape and fixing them together, without using a corner joint member 20 as at the outside corner portion 6. This reduces the number of parts and also eliminates the assembly process for the corner joint member 20, resulting in excellent workability. In this case, the leading end face of the inside panel 5 of one of the first and second panel bodies 2 or 3 is exposed on the outside corner side of the inside corner portion 7, but because the outside corner side of the inside corner portion 7 is between the opposing outer panel 4 and inner panel 5 of the double panel system, finishing of the leading end face of the exposed inside panel 5 can be omitted even though it is exposed on the outside corner side. On the other hand, since the corner joint member 20 that connects the tip end surface of the outer panel 4 is provided at the projected corner portion 6, finishing of the tip end surface of the outer panel 4 is also not required.

[0017] Furthermore, in this structure, at least one of the upper and lower edge portions (upper and lower end portions in this embodiment) of the outer and inner panels 4, 5 of the first and second panel bodies 2, 3 are fitted into fitting grooves 12a, 13a for the outer panel and fitting grooves 12b, 13b for the inner panel formed in an upper frame body 12 and a lower frame body 13 attached to body side members (upper rail member 9, lower rail member 10), respectively. The fitting grooves 13a for the outer panels and the fitting grooves 13b for the inner panels of the lower frame body 13 are arranged to be continuous in an L-shape at the protruding corners 6 and 7, and bead material 14 for elastically supporting the outer panel 4 and the inner panel 5 fitted into the fitting grooves 12a, 13a for the outer panels and the fitting grooves 12b, 13b for the inner panels are attached to the panel-facing side groove sides 12d, 13d of the fitting grooves 12a, 13a for the outer panels and the fitting grooves 12b, 13b for the inner panels. In the inside corner portion 7, the tip side of one of the bead materials 14 attached to the inner panel fitting groove 12b, 13b of one of the first and second panel bodies 2 or 3 is extended to a position where it can be abutted by the tip side end face 5c of the other inner panel 5 fitted into the inner panel fitting groove 12b, 13b of the other panel body 3 or 2, and the tip side end face 5c of the other inner panel 5 abuts against the extended portion 14a, and the tip side end face 5c of one of the inner panels 5 fitted into the inner panel fitting groove 12b, 13b of one of the panel bodies 2 or 3 abuts against the panel face 5b opposite the tip side of the other inner panel 5 abutted against the extended portion 14a, thereby connecting them. Furthermore, by configuring it in this manner, the inner panels 5 of the first and second panel bodies 2, 3 can be easily connected to each other at the inside corner portion 7, and the connected inner panels 5 are in a state where the opposing panel surface 5a of the inner panel 5 of one panel body 2 or 3 and the leading end surface 5c of the inner panel 5 of the other panel body 3 or 2 both abut against one of the bead materials 14 attached to the inner panel fitting groove 12b of one panel body 2.Therefore, the opposing panel surface 5a of one inner panel 5 and the leading end surface 5c of the other inner panel 5 can be arranged to be flush with high precision without any additional alignment, resulting in excellent workability and design.

[0018] Furthermore, in this device, the corner joint member 20 used in the projecting corner portion 6 has a vertically facing rectangular tubular shape that fits into the connecting portions between the outer panel fitting grooves 12a of the upper frame bodies 12 of the first and second panel bodies 2, 3 and between the outer panel fitting grooves 13a of the lower frame body 13, and is configured with a one-side connecting surface portion (fourth side surface portion 20d in this embodiment) against which the leading end face 4c of one of the outer panels 4 fitted into the outer panel fitting grooves 12a, 13a of one of the first and second panel bodies 2 or 3 abuts and is connected, and a other-side connecting surface portion (third side surface portion 20c in this embodiment) that is arranged at right angles to the one-side connecting surface portion and against which the leading end face 4c of the other outer panel 4 fitted into the outer panel fitting grooves 12a, 12b of the other panel body 3 or 2 abuts and is connected. Furthermore, by using a corner joint member 20 having such a configuration to connect the outer panels 4 of the first and second panel bodies 2, 3, an L-shaped connection between the outer panels 4 at the projected corner portion 6 can be easily made.

[0019] Of course, the present invention is not limited to the above embodiment (first embodiment). For example, in the inside corner portion 7, the first and second bead materials 14A, 14B are arranged so that the tip end portion of one bead material 14 (the first bead material 14A in the first embodiment) abuts against the other bead material 14 (the second bead material 14B in the first embodiment). By arranging the first and second bead materials 14A, 14B in this manner, it is possible to form an extension portion 14a at the tip side of the first bead material 14A against which the tip end face 5Bc of the second inner panel 5B can abut, and it is also possible to form an extension portion 14a at the tip side of the second bead material 14B against which the tip end face 5Ac of the first inner panel body 5A can abut. As a result, as in the second embodiment shown in Figure 6(A), the tip end face 5Ac of the first inner panel 5A can be abutted against the extension portion 14a formed on the second bead material 14B, and the tip end face 5Bc of the second inner panel 5B can be abutted against the panel surface 5Ab opposite the tip side of the first inner panel 5A abutted against the extension portion 14a, and the panels can be connected and fixed together with a joint material 19.

[0020] 6(B), the corner joint member 20 disposed in the projected corner portion 6 of the present invention can be used interchangeably even when outer panels 4 of different thicknesses T1 are assembled. In this case, the leading end surface 4Bc of the second outer panel 4B is connected and fixed to the third side surface portion 20c of the corner joint member 20, the leading end surface 4Ac of the first outer panel 4A is connected and fixed to the fourth side surface portion 20d, and the first and second side surfaces 20a, 20b are supported by the first and second presser members 15A, 15B, as in the first embodiment. However, since the thicknesses T2 of the first and second bead materials 14A, 14B differ depending on the thicknesses T1 of the outer panels 4A, 4B, the leading end of the bead material 14A or 14B may not be able to abut the chamfered portion 20e of the corner joint member 20 as in the first embodiment. In such a case, as shown in FIG. 6(B), by abutting the tip end of the first bead material 14A (or the second bead material 14B) against the fourth side surface portion 20d (or the third side surface portion 20c) of the corner joint member 20, the fourth side surface portion 20d is supported by the first bead material 14A, and the corner joint member 20 is thereby supported and positioned from three sides, the first, second and fourth side surface portions 20a, 20b and 20d. On the other hand, in the inside corner portion 7, when incorporating inner panels 5 of different thicknesses T1, the inner panels 5A and 5B of the first and second panels 2 and 3 can be connected to each other in the same manner as in the first embodiment by simply making the thicknesses T2 of the first and second bead materials 14A and 14B different to correspond to the thicknesses T1 of the first and second inner panels 5A and 5B. In the second and third embodiments, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0021] In this way, the first to third embodiments comprise a partition having first and second panel bodies with different surface directions to divide the interior space in a corner-like manner, and these first and second panel bodies are of a double-panel type consisting of a pair of inner and outer panels facing each other at a predetermined distance, and the partition is formed by connecting the tip ends of the outer panels of the first and second panel bodies and the tip ends of the inner panels of the first and second panel bodies in an L-shape at an outside corner portion and an inside corner portion, respectively, wherein the outside corner portion is connected using a corner joint member having a connecting portion to which the tip end face portions of the outer panels of the first and second panel bodies are connected, while the inside corner portion is configured to connect the tip side edge portions of the inner panels of the first and second panel bodies by abutting them together in an L-shape, thereby forming a partition invention characterized by this. By doing this, the tip edge portions of the inner panels can be connected to each other at the inside corner portion without using a corner joint member, thereby reducing the number of parts and the assembly process.In this case, even if the tip end face of the inner panel of one of the first or second panel bodies is exposed on the outside corner side of the inside corner portion, because the outside corner side of the inside corner portion is between the opposing outer panel and inner panel of the double panel system, it is possible to omit finishing processing of the exposed tip end face of the inner panel. Furthermore, in the inherent invention, at least one of the upper and lower edge portions of the outer and inner panels of the first and second panel bodies are fitted into fitting grooves for outer panels and fitting grooves for inner panels, respectively, formed in a frame body attached to a body side member, and the fitting grooves for outer panels and the fitting grooves for inner panels of the first and second panel bodies are arranged to be continuous in an L-shape at the external corners and internal corners, and bead materials for elastically supporting the outer and inner panels fitted into the fitting grooves are attached to groove side surfaces of the fitting grooves for outer panels and the fitting grooves for inner panels facing each other. On the other hand, at the inside corner portion, the tip side of one of the bead materials attached to the inner panel fitting groove of one of the first and second panel bodies is extended to a position where it can be abutted by the tip side end face of the other inner panel fitted into the inner panel fitting groove of the other panel body, and the tip side end face of the other inner panel is abutted against the extended portion, and the tip side end face of one of the inner panels fitted into the inner panel fitting groove of one of the panel bodies is abutted against the tip side panel face of the other inner panel abutted against the extended portion, thereby connecting them. By configuring it in this manner, the panel surface of one inner panel and the tip end surface of the other inner panel can be arranged to be flush with high precision without any additional alignment, resulting in excellent workability and design. Furthermore, in the inherent invention, the corner joint member used in the projecting corner portion is a rectangular tubular member facing up and down that is fitted into the connecting portion between the outer panel fitting grooves of the first and second panel bodies, and is characterized in that it has a one-side connecting surface portion that abuts and connects with the leading end face of one of the outer panels fitted into the outer panel fitting groove of one of the first and second panel bodies, and a other-side connecting surface portion that is arranged at a right angle to the one-side connecting surface portion and abuts and connects with the leading end face of the other outer panel fitted into the outer panel fitting groove of the other panel body. This configuration allows the outer panels to be easily connected in an L-shape at the projected corner portion.

[0022] Furthermore, the present invention can be embodied as fourth and fifth embodiments shown in Figures 7 and 8. In the fourth and fifth embodiments, a rectangular cylindrical corner joint member 21 having first to fourth side surface portions 21a to 21d and a chamfered portion 21e is disposed at the inside corner portion 7, similar to the outside corner portion 6. In this case, the fourth embodiment shown in Figure 7 uses a corner joint member 21 whose dimensions correspond to the thickness of the inner panel 5, while the fifth embodiment shown in Figure 8 employs an inner panel 5 that is thinner than the inner panel 5 of the fourth embodiment, but shares the corner joint member 21 of the same dimensions as in the fourth embodiment.

[0023] In the fourth embodiment shown in FIG. 7, the corner joint member 21 at the inside corner portion 7 is in a state in which the first and second side surface portions 21a, 21b are supported by the first and second bead materials 14A, 14B, and the chamfered portion 21e is supported by the first or second pressing member 15A, 15B. As a result, the corner joint member 21 can be supported and positioned from three sides: the first and second side surface portions 21a, 21b and the chamfered portion 21e. This also makes it possible to practice the present invention in this manner.

[0024] 8, if thinner inner panels 5A, 5B are used, the first and second bead materials 14A, 14B will be thicker accordingly, making it impossible to interpose the first and second bead materials 14A, 14B between the first and second side surface portions 21a, 21b of the corner joint member 21 and the first and second panel-facing groove side surfaces 12dA, 12dB. As a result, as shown in FIG. 8(A), a gap S will form between the first and second side surface portions 21a, 21b of the corner joint member 21 and the first and second panel-facing groove side surfaces 12dA, 12dB. As a result, the corner joint member 21 will be installed with play and will not be able to support the first and second side surface portions 21a, 21b. Therefore, if the thickness of the inner panel 5 is changed, a corner joint member 21 of the same dimensions cannot be used.

[0025] Therefore, in the fifth embodiment, as shown in Figure 8(B), a gap member 22 is fitted into the gap S, so that even if the thickness of the inner panel 5 is changed to a thinner one, the same corner joint member 21 as that of the outside corner portion 6 can be used for the inside corner portion 7, and the corner joint member 21 can be shared. Incidentally, the gap material 22 is sufficient as long as it can be fitted into the L-shaped gap S, and therefore it is preferable that it is a single piece bent into an L shape, but it is of course also possible to prepare two plate-shaped pieces and fit them into each gap S. In the fourth and fifth embodiments, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
