Description

[Technical Field]

[0001] The present invention relates to the technical field of connecting structures for panel bodies used to connect adjacent edge portions on the left and right sides of various panel bodies, such as panel bodies for booths such as toilet booths, and panel bodies for partition panels, in a continuous (flush) manner. [Background technology]

[0002] Generally, when erecting toilet booths or partition panels, for example when attaching the depth panel of a toilet booth to a section with a long depth dimension as in the embodiment of the present invention described below, adjacent panel bodies on the left and right may be connected in a continuous series.In this case, it has been proposed to form connecting grooves in the adjacent edge portions of each panel body and connect them via connecting fittings fitted into each connecting groove, thereby making it easy to connect adjacent panel bodies in a continuous series (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6905840 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional method, the groove-like joint formed as a gap between adjacent edges is closed by a joint piece provided on one of the connecting fittings, making the joint appear as if it were buried in the joint piece. However, when connecting the left and right panel bodies, there is a demand for the joint to be visible as a groove (a bottom joint (deep joint)), and the conventional method cannot meet this demand. Furthermore, in cases where the joint is buried using a joint piece provided on one of the connecting fittings, if the edge of the other panel body is deformed, for example due to an earthquake, there is a problem that a gap may occur between the joint piece and the edge of the other panel body, which may impair the appearance, and these are 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. The invention of claim 1 relates to a panel body connection structure configured to connect the edge portions of first and second panel bodies adjacent to each other on the left and right in a continuous manner with a groove-like joint formed between the edge portions via first and second connecting fittings incorporated into connecting grooves formed in the respective edge portions, the first and second connecting fittings comprising first and second spanning piece portions fixed with screws to the bottom surfaces of the connecting grooves, and a pair of first and second leg pieces extending from the first and second spanning piece portions respectively in a state spaced apart toward the inside in the front-rear direction with respect to the groove side surfaces of the connecting grooves, The first connecting fitting is formed with an outer leg piece extending from the first straddle piece portion facing the groove side of the connecting groove, and a first joint piece bent outward in the front-to-back direction from the outer leg piece to abut the edge of the first panel body, and the second connecting fitting is formed with a second joint piece bent outward in the front-to-back direction from the second leg piece to abut the edge of the second panel body, and the joint is maintained in a groove shape by the first and second joint piece portions facing each other with a gap in the left-to-right direction, forming the side portions of the joint.This is a connecting structure for panel bodies characterized in that The invention of claim 2 is a connecting structure of a panel body described in claim 1, characterized in that the joint is maintained by the tip of at least one of the first and second leg piece portions abutting against the corresponding second and first spanning piece portions. The invention of claim 3 is a connecting structure of a panel body described in claim 1 or 2, characterized in that the abutment of the first and second joint piece portions against the side portions of the corresponding joints is achieved by the tip portions of the first and second joint piece portions abutting, and no abutment is achieved other than at the tip portions. The invention of claim 4 is the panel body connection structure according to any one of claims 1 to 3, characterized in that the one leg piece portion forms a bottom surface portion of the joint. The invention of claim 5 is a panel body connection structure described in any one of claims 1 to 4, characterized in that the upper edge portions of the first and second panel bodies are formed with rail grooves into which both leg pieces of a U-shaped ceiling rail provided on the ceiling surface are fitted, and the upper edge portions of the first and second connecting fittings are formed with first and second fitting grooves into which both leg pieces of the ceiling rail are respectively fitted loosely. The invention of claim 6 is a connecting structure of a panel body described in claim 5, which cites claim 4, characterized in that one leg piece portion is a second leg piece portion and the other leg piece portion is a first leg piece portion, the first fitting groove is a wide one formed between the base ends of both first joint piece portions, and the second fitting groove is two narrow one formed at each base end of the second joint piece portion, and the second leg piece portion becomes the bottom portion of the joint. [Effects of the Invention]

[0006] By adopting the invention of claim 1, the joint formed between the edge portions of the first and second panel bodies is maintained as the side portions of the joint by the first and second joint piece portions formed in a state of abutting the edge portions of the corresponding first and second panel bodies on the first and second connecting fittings provided to connect the first and second panel bodies, facing each other with a gap in the left-right direction, so that it is easy to make it a bottom joint specification in which a groove-shaped joint remains, and further, because the first and second joint piece portions are formed on the first and second connecting fittings provided on the corresponding first and second panel bodies, when the edge portions of the first and second panel bodies deform, they will follow this deformation as much as possible and will not impair the appearance. By adopting the invention of claim 2, the first and second joint piece portions, which face each other with a gap in the left-right direction, can be easily connected by abutting the tip of at least one of the first and second leg piece portions against the corresponding second and first spanning piece portions, thereby improving the workability of the connecting work. By adopting the invention of claim 3, the first and second joint piece portions that abut the edge portions of the first and second panel bodies are configured so that their tips abut and no portions other than the tips abut.As a result, if the first and second connecting fittings are inserted too deeply into the connecting grooves, the non-abutting base end portions of the first and second joint piece portions will elastically deform in a direction approaching the edge portions of the panel bodies, maintaining the abutting state of the tips and avoiding the problem of gaps opening up. By adopting the invention of claim 4, the bottom surface of the joint, in which the first and second joint piece portions are the joint side portions, is constituted by one leg piece portion that fits externally.As a result, in addition to having the function of connecting the panel bodies together, the one leg piece portion also constitutes the bottom surface of the joint, allowing the component to be used for multiple purposes. By adopting the invention of claim 5, when the upper edge portions of the first and second panel bodies, which are connected with joints formed using the first and second connecting fittings, are assembled into the ceiling rail, first and second fitting grooves are formed in the upper edge portions of the first and second connecting fittings for fitting the leg piece portions of the ceiling rail into them.As a result, the first and second connecting fittings can be made long enough to reach the upper edge portions of the first and second panels, and the first and second connecting fittings will not be short and incomplete, reaching only to the lower end of the leg piece portion of the ceiling rail, resulting in an excellent appearance. By adopting the invention of claim 6, in which one leg piece portion is the second leg piece portion and the other leg piece portion is the first leg piece portion, the first fitting groove is one wide groove formed between the base ends of both first joint piece portions, and the second fitting groove is two narrow grooves formed at each base end of the second joint piece portion.As a result, the second connecting fitting has the second leg piece portion remaining without being cut out, forming the bottom portion of the joint, and the bottom portion of the joint can be sealed up to the upper edge of the panel body connecting portion, thereby preventing the inside and outside from being seen through this.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a front panel for constituting a toilet booth, and 2 denotes a depth panel. These front and depth panels 1, 2 are arranged to form a T or L shape to constitute the toilet booth, and both are long members extending between a floor rail 3 provided on a floor surface F and a ceiling rail 4 provided on a ceiling surface H. An opening that serves as an entrance / exit E is formed in the front panel 1, and a door body 5 is provided at the entrance / exit E so as to be able to open and close freely, all as in the conventional case. The present invention is implemented in the depth panel 2, and the configuration of the depth panel 2 will be described in detail below. However, the directions of "left and right" in this invention are defined for convenience as left and right when the depth panel 2, which is composed of the first and second panel bodies 6 and 7 as described below, is viewed from the front, and it goes without saying that the present invention is not limited to this.

[0009] As mentioned above, the depth panel 2 is formed by connecting the edge portions of a pair of adjacent first and second panel bodies 6, 7 in a continuous manner. Specifically, the first panel body 6 is the panel body on the depth wall W side, and the second panel body 7 is the panel body on the entrance / exit E side. Each panel body 6, 7 is formed by a pair of front and rear surface panels 8 (the surfaces of which are covered with decorative steel plates 8a), upper and lower horizontal frame members 9 and left and right vertical frame members 10 which form the four-sided frame of the first and second panel bodies 6, 7 and are sandwiched between the front and rear surface panels 8, and a filler material (core material) 11 which is filled between the front and rear surface materials 8. Connecting grooves 6a, 7a are formed in each of the vertical frame members 10, 10 that form the adjacent left and right edge portions of the first and second panel bodies 6, 7, and a first connecting fitting 12 is assembled into the connecting groove 6a of the first panel body 6, and a second connecting fitting 13 is assembled into the connecting groove 7a of the second panel body 7, so that the first and second panel bodies 6, 7 are connected in a series in the left-right direction via these first and second connecting fittings 12, 13, as described below.

[0010] On the other hand, a ceiling rail 4 is provided on the ceiling surface H, and the ceiling rail 4 is configured in a U shape with leg pieces 4b hanging down from the front and rear end edges of a spanning piece 4a which is fixed to the ceiling surface H via screws 4c, and the leg pieces 4b are assembled in a state where they fit into rail grooves 6b, 7b formed in the upper edge parts of the first and second panel bodies 6, 7. The ceiling rail 4 is fixed to the first and second panel bodies 6, 7 by fixing an upright piece 14b of an L-shaped mounting bracket 14 which is fixed to the bottom surface of the rail grooves 6b, 7b via screws 14a to one of the leg pieces 4b of the ceiling rail 4 via screws 14c at a position above the upper edge parts of the first and second panel bodies 6, 7. In response to this, a floor rail 3 is provided on the floor surface F, and the floor rail 3 is configured in a square shape with leg pieces 3b standing up from both the front and rear end edges of a spanning piece 3a which is fixed to the floor surface F via screws 3c, while a square-shaped baseboard 15 is provided on the lower end edges of the first and second panel bodies 6, 7. The leg piece 15a of the baseboard 15 is fitted onto the leg piece 3b of the floor rail 3, thereby enabling the lower edge portions of the first and second panel bodies 6, 7 to be attached to the floor surface F. The first and second panel bodies 6, 7 to be attached must be adjusted up and down, and for this purpose a well-known floor jack device 16 is provided inside the baseboard 15. The baseboard 15 can be adjusted up and down by operating the floor jack device 16, and the first and second panel bodies 6, 7 can be placed on top of the adjusted baseboard 15, allowing the first and second panel bodies 5, 6 to be assembled in a state where they are positioned in the up and down direction. Details of this are omitted as they are not directly related to the present invention, but if necessary please refer to the description in Patent Document 1 mentioned above, for example.

[0011] As mentioned above, the first and second connecting fittings 12, 13 are incorporated into the connecting grooves 6a, 7a formed in the edge portions of the first and second panel bodies 6, 7. In this case, the first and second connecting fittings 12, 13 are incorporated by attaching and fixing the first and second spanning pieces 12a, 13a to the groove bottom surfaces 6c, 7c of the connecting grooves 6a, 7a via screws 17. Furthermore, the first and second spanning pieces 12a, 13a have first and second leg pieces 12b, 13b that extend toward the adjacent first and second panel bodies 7, 6 (outward in the left-right direction) while being spaced inward in the front-to-back direction from the groove side surfaces 6d, 7d of the connecting grooves 6a, 7a. In this embodiment, the first leg piece 12b is formed so as to be positioned further inward in the front-to-rear direction than the second leg piece 13b, so that when the first and second connecting fittings 12, 13 are connected in a butt-to-face relationship, the pair of first leg pieces 12b fit internally between the pair of second leg pieces 13b in a sliding contact state; conversely, the pair of second leg pieces 13b fit externally to the pair of first leg pieces 12b in a sliding contact state, forming a male-female fitting configuration. In this case, the second leg piece 13b is configured to have a connecting structure in which the tip end 13c abuts against the first spanning piece 12a in a butt-like manner, and when this connecting structure is formed, a positioning structure is formed in which a groove-shaped joint M is formed between the opposing end edges 6e, 7e of the first and second panel bodies 6, 7 (the edge edges of the surface plate 8 and the vertical frame member 10), where the end edges 6e, 7e form side edges (formal side edges) with a gap between them.

[0012] The first connecting fitting 12 has an outer leg piece 12c formed from the front-to-back edge of the first spanning piece 12a, which has a gap (a gap into which the second leg piece 13b fits loosely inward in the front-to-back direction) between it and the first leg piece 12b and extends in an opposing position, abutting or close to the groove side surface 6d of the connecting groove 6a, and a first joint piece 12d is bent outward in the front-to-back direction from the tip of the outer leg piece 12c, abutting the edge portion 6e of the first panel body 6 but spaced apart from the edge portion 7e of the second panel body 7. In contrast, the second connecting fitting 13 has a second joint piece 13d bent from the left-right middle portion of the second leg piece 13b outward in the front-to-back direction to abut against the edge portion 7e of the second panel body 7, but spaced apart from the edge portion 6e of the first panel body 6. When the above-mentioned connecting structure is used, the joint M is configured so that the first and second joint piece portions 12d, 13d become the actual side portions, and the portion of the second leg piece portion 13b corresponding to the joint M becomes the actual bottom portion, and is formed (maintained, remains) in the shape of a concave groove. In this case, the contact of the first and second joint piece portions 12d, 13d with the edge portions 6e, 7e of the first and second panel bodies 6, 7 is such that the tip portions 12f, 13f are structured to protrude outward in the left-right direction, so that the tip portions 12f, 13f contact the open ends of the edge portions 6e, 7e, but do not contact portions other than the tip portions 12f, 13f. As a result, when the second connecting fitting 13 shown in Figure 9(A) is used as an example, If the second connecting fitting 13 is twisted in too far, the base end portion of the second joint piece 13d that is not abutting the edge portion 6e will elastically deform within the range of the non-abutting gap, and the tip portion 13f will maintain abutment against the edge portion 6e, thereby preventing the tip portion 13f from separating from the edge portion 6e and creating a gap, as occurs when the entire second joint piece 13d abuts against the edge portion 6e as shown in Figure 9(B).

[0013] On the other hand, as mentioned above, rail grooves 6b, 7b are formed in the upper edge portions of the first and second panel bodies 6, 7, and the leg piece portions 4b of the ceiling rail 4 are fitted into these rail grooves 6b, 7b. The first and second connecting fittings 12, 13 also have first and second fitting grooves 12e, 13e (hatched areas in Figure 5) formed in their upper edge portions to fit the leg piece portions 4b of the ceiling rail 4 into. The first fitting groove 12e formed in the first connecting fitting 12 is a single wide groove that is cut out and extends between the base ends of the front and rear first joint piece portions 12d, that is, from the base end of one first joint piece portion 12d in the front-to-rear direction, through one outer leg piece portion 12c, the first straddling piece portion 12a including both first leg piece portions 12b, the other outer leg piece portion 12c, and to the base end of the other first joint piece portion 12d.

[0014] In contrast, the second mating groove 13e formed in the second connecting fitting 13 is formed by cutting out the base ends of both the front and rear second joint piece portions 13d, with the second spanning piece portion 13a and the pair of second leg piece portions 13b remaining uncut.As a result, the second mating groove 13e consists of two narrow grooves, and when the first and second leg piece portions 12b, 13b are mated together male and female, the inner first leg piece portion 12b is cut out and the outer second leg piece portion 13b remains uncut. In addition, in this embodiment, the second spanning portion 13a has front and rear end edge portions 13g that protrude outward in the front-to-rear direction further than the extending portion of the second leg portion 13b and are closely opposed to (or abut against) the groove side surface 7d of the connecting groove 7a, thereby positioning the installation position, and the front and rear end edge portions 13g of the second spanning portion 13a are also cut out.

[0015] When the first and second panel bodies 6, 7 having the first and second connecting fittings 12, 13 thus assembled are assembled to the floor rail 3 and the ceiling rail 4, the so-called "go and come" method of assembly can be used. This method will be explained using Figure 10, taking the assembly of the second panel body 7 as an example. First, the second panel body 7 is fitted into the ceiling rail 4 with the second panel body 7 tilted in the front-to-back direction, and then the second panel body 7 is lifted while correcting the tilt to a vertical position, thereby deepening the fit of the rail groove 7b into the ceiling rail 4. This positions the lower edge of the second panel body 7 higher than the positioning material 15b provided on the upper surface above the baseboard 15. By lowering the second panel body 7 in this state, the second panel body 7 is placed in an assembled position where, in a vertical position, the rail groove 7b fits into the ceiling rail 4 and the positioning material 15b fits into the lower rail groove 7f provided on the lower edge of the second panel body 7. This allows the upper and lower edge portions of the second panel body 7 to be fitted into the ceiling rail 4 and the floor rail 3. The second panel body 7 can then be moved to the set position in the left-to-right direction, and the second panel body 7 can be attached by fastening the mounting bracket 14 to the ceiling rail 4 with the screws 14c as described above. A similar installation is performed for the first panel body 6.

[0016] When assembling the upper edge portions of the first and second panel bodies 6, 7 to the ceiling rail 4, the leg portion 4b of the ceiling rail 4 is fitted into the first and second rail fitting grooves 12e, 13e formed in the upper edge portions of the first and second connecting fittings provided on the first and second panel bodies 6, 7, and as a result, the first and second connecting fittings 12, 13 can be made long enough to reach the upper edge portions of the first and second panel bodies 6, 7. Moreover, in this case, the second rail fitting groove 13e is not wide in the front-to-back direction like the first rail fitting groove 12e, but is narrow and formed at the base end of the second joint piece portion 13d, and the second leg piece portion 13b remains without being cut out, so that the second leg piece portion 13b can also be used as the actual bottom portion of the joint M. Furthermore, unlike the case where the second fitting groove 13e is made wide with the notch extending up to the first leg piece 12b, the inside and outside of the toilet booth are not visible through the cutout portion, and the booth can be closed off, thereby improving security and design.

[0017] In the present embodiment configured as described above, the first and second panel bodies 6, 7 adjacent to each other on the left and right are connected in a continuous manner with the edge portions 6e, 7e of the first and second connecting fittings 12, 13 being connected together with a joint M. In this case, the first and second connecting fittings 12, 13 are configured to include first and second spanning portions 12a, 13a that are attached and fixed to the groove bottom surfaces 6c, 7c of the connecting grooves 6a, 7a formed in the edge portions 6e, 7e of the first and second panel bodies 6, 7 with screws 17, and a pair of first and second leg pieces 12b, 13b that extend from the first and second spanning portions 12a, 13a toward the adjacent second and first panel bodies 7, 6, spaced apart inward in the fore-and-aft direction from the groove side surfaces 6d, 7d of the connecting grooves 6a, 7a. In this embodiment, the connecting configuration is such that the first leg piece 12b is fitted between the second leg pieces 13b.

[0018] In this case, the first connecting fitting 12 has an outer leg piece 12c extending from the first spanning piece 12a in a position facing the groove side 6d of the connecting groove 6a formed in the first panel body 6, and is further bent from the outer leg piece 12c outward in the front-to-back direction so that the first joint piece 12d abuts against the edge 6e of the first panel body 6, while the second connecting fitting 13 has a second joint piece 13d bent from the middle of the second leg piece 13b in a position facing outward in the front-to-back direction so that it abuts against the edge 7e of the second panel body 7, and since the first and second joint piece portions 12d, 13d face each other with a gap in the left-to-right direction, the joint M formed between the edge portions 6e, 7e of the first and second panel bodies 6, 7 is maintained as a groove shape in which the first and second joint piece portions 12d, 13d essentially form the side portions of the joint M. As a result, it is easy to achieve a bottom joint specification that includes a groove-shaped joint M when connecting the first and second panel bodies 6, 7 in a continuous manner. Furthermore, the first and second joint pieces 12d, 13d that essentially constitute the side portions of the joint M are separate pieces formed on the first and second connecting fittings 12, 13 attached to the corresponding first and second panel bodies 6, 7, respectively. Therefore, if the edge portions 6e, 7e of the first and second panel bodies 6, 7 are deformed, they will easily follow this deformation, preventing gaps from occurring.

[0019] Furthermore, in this case, by assembling the first and second connecting fittings 12, 13 together so that the tip edge of the second leg piece 13b abuts the first spanning piece 12a, the joint M is formed in a state where it is maintained in a groove shape, which makes it easy to connect the first and second panel bodies 6, 7 together while the joint M is present, improving the workability of the connecting work.

[0020] Furthermore, in this device, the first and second joint piece portions 12d, 13d, which constitute the actual side portions of the joint M, abut against the corresponding edge portions 6e, 7e only at the tip portions 12f, 13f of the first and second joint piece portions 12d, 13d, and no portions other than these tip portions 12f, 13f abut.As a result, as shown in Figure 9, if the first and second connecting fittings 12, 13 are screwed too far (too deep) into the connecting grooves 6a, 7a, the non-abutting base end portions of the first and second joint piece portions 12d, 13d will elastically deform in a direction approaching the edge portions 6e, 7e, maintaining the abutting state of the tip portions, thereby avoiding the problem of gaps being formed between the edge portions 6e, 7e.

[0021] Furthermore, in this device, rail grooves 6b, 7b are formed on the upper edges of the first and second panel bodies 6, 7, into which the leg pieces 4b of the U-shaped ceiling rail 4 provided on the ceiling surface H fit. Similarly, first and second fitting grooves 6e, 7e are formed on the upper edges of the first and second connecting fittings 12, 13, into which the leg pieces 4b of the ceiling rail 4 fit loosely. As a result, the first and second connecting fittings 12, 13 can be made long, reaching all the way to the upper edges of the first and second panels 6, 7, rather than being short and incomplete, reaching only to the lower ends of the leg pieces 4b of the ceiling rail 4, resulting in an excellent appearance.

[0022] Moreover, in this case, the first fitting groove 12e formed in the first connecting fitting 12 is wide enough to fit loosely over the entire space between both leg pieces 4b of the ceiling rail 4, but the second fitting groove 13e formed in the second connecting fitting 13 is designed to fit loosely over only the leg piece 4b of the ceiling rail 4, so the second leg piece 13b remains uncut, and two narrow grooves are formed at each base end of the second joint piece 13d. As a result, the second leg piece 13b that remains uncut forms the bottom surface of the joint M where the ceiling rail 4 fits, and the bottom surface of the joint M is blocked up to the upper edge of the connecting portion by the second leg piece 13b, preventing people from seeing inside and outside through this gap, improving security and design.

[0023] Of course, the present invention is not limited to the above-described embodiment, but may be embodied in a second embodiment shown in FIG. In this structure, the second leg piece 13b formed on the second connecting fitting 13 is fitted between the first leg piece 12b formed on the first connecting fitting 12, and in this structure, as in the first embodiment, the outer leg piece 12c and the first joint piece 12d are formed in the first connecting fitting 12 in the same manner, and the second joint piece 13d is formed in the same manner on the second connecting fitting 13, and these first joint piece 12d and second joint piece 13d form the side portions of the joint M, but the bottom portion of the joint M is formed by the first leg piece 12b. In this case, the first mating groove 12e formed in the first connecting fitting 12, shown by the hatched area in Figure 11, is a single wide groove cut out between the base end portions of the pair of front and rear first joint piece portions 12d, while the second mating groove 13e formed in the second connecting fitting 13 only extends to the tip portion 13g beyond the second leg piece portion 13b of the second spanning piece portion 13a, and the second leg piece portion 13b remains uncut out, forming a pair of narrow grooves. Furthermore, in this case, in order to form the joint M, the tip portion 12g of the first leg piece portion 12b abuts against the base end portion of the second joint piece portion 13d, thereby positioning the male-female fitting between the first and second connecting fittings 12, 13, and the second leg piece portion 13b becomes the bottom portion of the joint M in the upper edge portion where the first fitting groove 12e is formed, and the first leg piece portion 12b becomes the bottom portion of the joint M in the portion where the first fitting groove 12e is not formed, so the present invention can also be implemented in this way. [Industrial Applicability]

[0024] The present invention can be used as a panel body connecting structure used to connect various panel bodies in a series, such as panel bodies for booths such as toilet booths, and panel bodies for partition panels. [Explanation of symbols]
