Description

[Technical Field]

[0001] The present invention relates to the technical field of airtight material mounting structures in partition panels that are installed to divide indoor spaces. [Background technology]

[0002] Generally, partition panels are installed to separate the interior spaces of buildings such as buildings. Among such partition panels, at least one of the adjacent panel bodies on the left and right can be opened or closed, and the interior space can be divided into a usage space that is constantly used by people, such as an office space or living space, and a storage space with a narrow depth for storing various types of equipment such as machinery, appliances, machinery devices, and air conditioning units.It has been proposed that the openable and closable panel body, which is normally locked, can be unlocked as needed to allow access from the usage space to the storage space (see, for example, Patent Document 1). Such partition panels require airtightness to prevent sounds emitted from machinery placed in the storage space from leaking into the space in use. Therefore, in the conventional partition panels, airtightness at the joints between adjacent panel bodies was ensured by abutting an airtight material for the joints provided at the leading edge of one panel body against the leading edge of the other panel body.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-97947 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional product, the abutment portion provided on the main body of the airtight material for the joint joint is configured to extend to one side in the front-to-back direction, and when the panel body is in a closed position, it abuts against the other panel body from the front-to-back direction to ensure airtightness. With such airtight materials for joint joints, the state in which the abutting portion abuts against the panel body is an important factor in ensuring airtightness, but in the conventional configuration in which the abutting portion abuts from the front and back, the abutting state of the abutting portion cannot be directly seen because it is obstructed by the groove in the airtight material for joint joints into which the main body portion is inserted and attached, or the abutting piece portion on the panel body with which the abutting portion abuts.As a result, there are problems such as the work of checking the abutting state of the abutting portion being time-consuming and inefficient to work with, and these are the issues that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in consideration of the above-mentioned actual situation and with the aim of solving these problems.The invention of claim 1 is an airtight material mounting structure for a partition panel, which is composed of panel bodies adjacent to each other on the left and right to divide an interior space into front and back, and at least one of the adjacent panel bodies is configured to be able to open and close freely, and when the panel bodies are closed, the gap at the joint where the door edge side end surfaces of adjacent panel bodies face each other is airtightly sealed via an airtight material for the joint provided on one of the panel bodies, and the airtight material for the joint portion is configured to have a main body portion that is incorporated into the airtight material groove for the joint portion provided on the door edge side end surface of one of the panel bodies, and an abutment portion that extends from the main body portion toward the other panel body in the left-right direction and abuts the door edge side end surface of the other panel body when the panel bodies are closed. The invention of claim 2 is an airtight material mounting structure for a partition panel described in claim 1, characterized in that the main body of the airtight material for the joint section is incorporated into the airtight material groove for the joint section so that its position can be freely adjusted in the left-right direction. The invention of claim 3 is an airtight material mounting structure for a partition panel described in claim 1, characterized in that one of the adjacent panel bodies on the left and right is set to a fixed type that does not move when opening or closing, or a sliding type that moves in the left and right direction, and the other panel body is set to a swing door type in which the end edge portion on the door tail side is supported on a shaft so that it can swing freely in the front and back directions, and the airtight material groove for the joining portion provided in one panel body does not protrude in the front and back directions from the panel body, but is provided in a position biased to one side in the front and back direction, which is the closing direction of the other panel body. The invention of claim 4 is an airtight material mounting structure for a partition panel described in claim 3, characterized in that the abutment portion of the airtight material for the joint portion can be seen from the gap on one side of the joint portion in the front-to-rear direction when the panel body is in a closed state. The invention of claim 5 is an airtight material mounting structure for a partition panel described in claim 3, characterized in that the airtight material for the joint portion is formed in a fin-like shape, with the abutment portion bulging out from the other front-to-back side edge of the main body portion and curved to one side in the front-to-back direction toward the other panel body. The invention of claim 6 is an airtight material mounting structure for a partition panel described in claim 3, characterized in that upper and lower horizontal airtight materials provided on the main body side member abut the upper and lower ends of one side portion in the front-to-back direction of adjacent panel bodies on the left and right, and the upper and lower horizontal airtight materials are provided in a continuous series on the left and right at the joint portions of adjacent panel bodies because the airtight material groove for the joint portion does not protrude in the front-to-back direction. The invention of claim 7 is an airtight material mounting structure for a partition panel described in claim 6, characterized in that the door trailing edge portion of the other panel body is pivotally supported on a main body side member so as to be able to open and close freely, and the door trailing side portion on one side of the front-to-rear direction of the other panel body abuts against the abutment portion of a vertical airtight material provided on the main body side member, and the horizontal airtight material and the vertical airtight material are arranged at the corner portion where the two airtight materials intersect so that the main body portion of one airtight material enters the gap portion of the main body portion that has been cut out while leaving the abutment portion of the one airtight material, while the abutment portion of the airtight material at the portion where the main body portion has been cut out is arranged overlapping the abutment portion of the other airtight material. [Effects of the Invention]

[0006] By adopting the invention of claim 1, in a configuration in which at least one of the adjacent panel bodies, which are components of a partition panel that divides an interior space into front and back, is configured to be freely opened and closed, when the gap at the joint of the panel bodies in the closed state is airtightly sealed using a joint airtight material provided on one of the panel bodies, the abutment portion extending from the main body of the joint airtight material abuts against the door edge side end face portion of the other panel body, as a result of which the abutment portion can be arranged in a state where it can be seen from the gap at the joint, making it easier to optimally install the joint airtight material in the joint airtight material groove. By adopting the invention of claim 2, the main body of the airtight material for the joint joint is incorporated into the groove of the airtight material for the joint joint so that its position can be freely adjusted in the left-right direction, making it easy to adjust the abutment state of the abutting part against the panel body. By adopting the invention of claim 3, when one of the adjacent panel bodies on the left and right is set to a fixed type that does not move when opening or closing, or a sliding type that moves left and right, and the other panel body is set to a swing door type in which the end edge portion on the door tail side is supported so that it can swing freely in the front and back directions, the airtight material groove for the joint portion provided on one panel body does not protrude in the front and back directions from the panel body, and is provided in a position biased to one side in the front and back direction, which is the closing direction of the other panel body.As a result, at the final stage when the panel body finishes closing, a sliding contact is made with the panel body accompanied by elastic deformation of the contact portion, thereby reducing wear due to the sliding of the contact portion and achieving a longer lifespan. By adopting the invention of claim 4, the contact portion of the airtight material for the joint can be seen from the gap on one side of the joint in the front-to-rear direction when the panel body is in the closed state, which makes it possible to make adjustments while visually checking the contact state of the contact portion, thereby improving workability. By adopting the invention of claim 5, the airtight material for the joint portion is formed in a fin-like shape, with the abutment portion bulging out from the other front-to-back end edge of the main body portion toward the other panel body while curving to one side in the front-to-back direction.As a result, the fin-like abutment portion extends in a cantilevered manner along the closing direction of the other panel body which swings in the front-to-back direction, allowing the abutment portion to abut smoothly against the panel body and achieving a high airtight effect. By adopting the invention of claim 6, at the joint joint, the upper and lower horizontal airtight materials provided on the main body side member abut against the upper and lower ends of one side surface in the front-to-back direction of the panel body adjacent to the left and right sides of the panel body where airtightness can be ensured by the airtight material for the joint joint.In this case, since the groove of the airtight material for the joint joint does not protrude in the front-to-back direction, the upper and lower horizontal airtight materials can be provided as a continuous piece on the left and right sides even at the joint joint between adjacent panel bodies, thereby achieving higher airtightness. By adopting the invention of claim 7, the door trailing edge side edge portion of the other panel body is pivotally supported on the main body side member so as to be able to open and close freely, and the door trailing edge side portion on one side of the front-to-rear direction of the other panel body is abutted against the abutment portion of the vertical airtight material provided on the main body side member.In this case, the horizontal airtight material and the vertical airtight material are arranged at the corner where the two airtight materials intersect, so that the main body portion of one airtight material enters the gap of the main body portion that was cut out while leaving the abutment portion of one airtight material, and the abutment portion of the airtight material at the part where the main body portion was cut out is arranged overlapping with the abutment portion of the other airtight material.As a result, at the corner where the horizontal airtight material and the vertical airtight material intersect, the abutment portions that are arranged overlapping when the panel body is closed are elastically deformed in an overlapping state by the closing panel body, thereby achieving high airtightness even at the corner.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a partition panel that separates the interior space of a building into a front-to-back space, and the partition panel 1 is provided to separate the interior space into a space S that is constantly used by people, such as an office space or a living space, and a storage space T that has a narrow depth and is used to store various devices such as machinery and equipment, machinery devices, and air conditioners. The partition panel 1 of this embodiment is made up of a total of four panel bodies P1 to P4 arranged in a series adjacent to each other on the left and right. The first and fourth panel bodies P1, P4 on the left and right outer sides are configured as swing doors, with the outer left-right end edges of the door tails pivoted to the left and right vertical frames (vertical supports) 2, which are the main body side members, via hinges 3 so that they can swing freely back and forth in the forward direction and open to the front use space S.The second and third panel bodies P2, P3 on the left and right inner sides are of the sliding type, which are opened and closed left and right by running rollers 7 rolling on guide rails 6 on the floor surface F side, with an anti-sway body 5 fitted into an anti-sway rail 4 on the ceiling surface H side so that it can move freely left and right in order to prevent vibration (falling) in the forward and backward direction.All of these are conventional in that they are of the sliding type. In the following explanation, when the first to fourth panel bodies P1 to P4 are collectively described, they will be referred to as "panel body P", and when the individual panel bodies are described separately, they will be referred to as first to fourth panel bodies P1 to P4. In addition, the panel body P in this embodiment is a component of the partition panel 1 used to divide the interior space into a use space S and a storage space T from the front and back as described above, and therefore, for convenience, the use space S side is defined as the front side (front side, surface side) and the storage space T side is defined as the rear side (back side, back surface side) using the panel body P as the reference, and the left and right directions are defined in accordance with the description in the drawings, where the view from the use space S side is the front view, but it goes without saying that the present invention is not limited to these orientations.

[0009] The panel body P basically adopts a general-purpose structure using upper and lower horizontal frame members 8, 9, left and right vertical frame members 10, 11, front and rear panel members (front and rear panel members) 1a, 1b, and filler material 1c contained within and surrounding these. For the second and third panel bodies P2, P3, a vibration prevention body 5 is provided on the upper horizontal frame member 8, and a running roller 7 is provided on the lower horizontal frame member 9. Furthermore, for the left and right vertical frame members 10, 11 of the first and fourth panel bodies P1, P4, the one on the outside in the left-right direction where the hinge 3 is provided is defined for convenience as the trailing edge vertical frame member 10, and the one on the inside in the left-right direction as the leading edge vertical frame member 11. For the second and third panel bodies P2, P3, the one on the outside in the left-right direction adjacent to the first and fourth panel bodies P1, P4 is defined for convenience as the trailing edge vertical frame member 10, and the one on the inside in the left-right direction where the second and third panel bodies P2, P3 join together is defined for convenience as the leading edge vertical frame member 11. The panel body P constructed in this manner is arranged with an upper rail material 12 provided on the ceiling surface H and a lower rail material 13 provided on the floor surface F, with an upper and lower gap (gap) between them.

[0010] The upper and lower rail members 12, 13 are made of gypsum to close the gap between the upper and lower rail members 12, 13 and the panel body P on the storage space T side, thereby improving sound insulation, fire resistance, and other performance features, and upper and lower board members 14, which are long in the left-right direction, are attached via board attachment parts 15. Next, we will explain the structure for attaching the lower board member 14 to the lower rail member 13. Although the upper board member 14 differs slightly from the lower board member 14 in terms of dimensions and the fact that it is configured upside down, it uses the same attachment structure as the lower board member 14, so details will be omitted.

[0011] The lower rail material 13 is square-shaped with an opening at the top, which is inward in the vertical direction, and the bottom piece 13a is attached and fixed to the floor surface F via screws 13b.A board material attachment portion 15 for attaching a board material 14 is arranged on the leg piece 13c on the rear side in the front-to-rear direction, which is on the storage space T side of the lower rail material 13. The board material mounting portion 15 is configured with an attachment piece member 15a whose outer end in the vertical direction is open so as to fit externally onto both leg piece portions 13c of the lower rail material 13, and the attachment piece member 15a is U-shaped with front and rear leg piece portions 15aa, 15ab and a bottom piece portion (top piece portion) 15ac, and of the front and rear leg piece portions 15aa, 15ab extending outward in the vertical direction, the front leg piece portion 15aa serves as a fixing piece for fixing the attachment piece member 15a to the front leg piece portion 13c in the vertical direction of the lower rail material 13 via a screw 15ad, while the rear leg piece portion 15ab constitutes the first inner piece portion 15ab which is the outer half in the vertical direction of the front piece portion (front-to-back inner piece portion) of the board material mounting portion 15.

[0012] On the other hand, the vertical inner half of the front-to-back inner piece that constitutes the board material mounting portion 15 is formed as an auxiliary piece member 15b, which is formed in an L-shape with a horizontal piece portion 15ba fixed to the bottom piece portion 15ac of the mounting piece member 15a via a screw 15bc, and a vertical piece portion 15bb extending inward in the vertical direction from the rear end edge of the horizontal piece portion 15ba. By attaching and fixing the horizontal piece portion 15ba of the auxiliary piece member 15b to the bottom piece portion 15ac of the mounting piece member 15a via a screw 15bc, the vertical piece portion 15bb becomes flush with the first inner piece portion 15ab of the mounting piece member 15a, and thereby the vertical piece portion 15bb forms the second inner piece portion 15bb, which is the vertical inner half of the front piece portion of the board material mounting portion 15. Then, by gluing (or adhesively attaching) the panel body side surface 14a, which is on one side of the board material 14 in the front-to-rear direction (the side of the use space S, the front side), to the first and second inner piece portions 15ab and 15bb, which are now flush with each other, the board material 14 is attached in a state where the panel body side surface 14a is covered by the first and second inner piece portions 15ab and 15bb.

[0013] The side 14b of the attached board material 14 opposite the panel body (rear side in the fore-and-aft direction) is covered with an outer piece member 15c. In this embodiment, the outer piece member 15c is described as being connected to the first inner piece portion 15ab, but it may also be connected to the second inner piece portion 15bb. In this embodiment, the first inner piece 15ab has a bent piece 15ae formed at the outer edge in the vertical direction, which is bent toward the rear side (toward the storage space T), and a locking groove 15af is formed at the tip edge of the bent piece 15ae. Meanwhile, a locking protrusion 15ca is formed on the vertical outer end of the outer piece member 15c in correspondence with the locking recessed groove 15af. Then, with the board material 14 adhered (fixed) to the first and second inner piece portions 15ab, 15bb, and with adhesive (or double-sided adhesive tape) applied (or stuck) to the opposite-panel-body side surface 14b of the board material 14, the locking protrusion 15ca is fitted into the locking recessed groove 15af at the corner where the leading edge of the folded piece portion 15ae and the vertical outer end of the outer piece member 15c butt against each other at a right angle, thereby connecting the folded piece portion 15ae (first inner piece portion 15ab) and the outer piece member 15c and bonding the board material 14 to the outer piece member 15c.

[0014] By configuring the board material 14 in this manner, both the front and rear sides are surrounded and contained within the board material mounting portion 15, which is formed in a cylindrical shape by the first and second inner piece portions 15ab, 15bb and the outer piece member 15c, and the board material 14 can be attached to the lower rail material 13 by attaching and fixing the front leg piece portion 15aa of the mounting piece member 15a in this configuration to the front leg piece portion 13c of the lower rail material 13 via the screw 15ad. Incidentally, in this embodiment, the board material 14 is attached using an adhesive (adhesive), but this is not limitative, and it may be configured to be fixed to the first inner piece portion 15ab with screws, for example.

[0015] In this way, the board material 14 is attached to the lower rail material 13. The method for this is as follows: a first screw fixing step of fixing a side piece portion 15ba of an auxiliary piece member 15b, which has a second inner piece portion 15bb formed inward in the vertical direction, to a bottom piece portion 15ac of an attachment piece member 15a, which has a first inner piece portion 15ab formed extending outward in the vertical direction, with a screw such that the first and second inner piece portions 15ab, 15bb are flush with each other; a board material disposing step of disposing the board material 14 in a state in which the panel body side surface 14a is covered on the first and second inner piece portions 15ab, 15bb that are flush with each other; a board material storing step of connecting the outer piece member 15c to the first inner piece portion 15ab to form a cylindrical board material mounting portion 15 so as to cover the opposite panel body side surface 14b of the arranged board material 14, and surrounding and storing the board material 14 in the board material mounting portion 15; a second screw fixing step of fixing the front leg piece portion 15aa of the attachment piece member 15a to the lower rail material 13 via a screw 15ad; Each of the above steps will be carried out, but the first screw fixing step, board material arrangement step, and board material storage step will be carried out in the factory, and once these steps have been carried out, the board material stored in the board material mounting section will be transported to the site, and the second screw fixing step will be carried out on site. By configuring this to be able to simplify the steps at the site and contribute to improving workability, when all of these steps are to be carried out on site, it is preferable that the second screw fixing step be the last step from the standpoint of workability, but it may also be the first step to be carried out, or a step carried out in the middle, and these steps can be selected as appropriate by the worker on site.

[0016] Furthermore, at the inner end of the board material mounting portion 15 configured in this manner, a mounting groove 18 for a horizontal airtight material is formed for mounting a horizontal airtight material 17 that abuts against the rear side of the outer end edge of the panel body P in the vertical direction to provide airtightness. The horizontal airtight material 17 is configured to include a main body portion 17a that is fitted into the mounting groove 18 for the horizontal airtight material, and a fin-shaped abutment portion 17b that bulges in an arc from the inner edge portion of the main body portion 17a in the vertical direction so as to abut against the panel body P in an elastically deformed state and thereby provide airtightness.The horizontal airtight material groove 18 is configured in the shape of a groove with an opening on the panel body P side, consisting of an outer vertical groove side piece portion 15bd and a groove bottom piece portion 15be that are formed by bending the inner vertical portion of the second inner piece portion 15bb into an L shape, and an inner vertical groove side piece portion 15cb that is formed by bending the inner vertical portion of the outer piece member 15c toward the panel body P side.

[0017] In this case, the second inner piece 15bb is bent so that the vertical inner portion is biased (bulged) toward the panel body P, whereby the mounting groove 18 for the lateral airtight material has a deep groove shape in which the opening end of the vertical outer groove side piece 15bd is biased toward the panel body P together with the vertical inner groove side piece 15cb. With this configuration, the lateral airtight material 17 is configured so that the main body 17a can be deeply fitted into the lateral airtight material recessed groove 18 for stable mounting. The airtight material 17 used in this case has multiple peelable adjustment pieces 17c attached in a stacked manner to the groove bottom side of the main body 17a, and these adjustment pieces 17c can be adjusted so that the abutment state of the abutment part 17a against the panel body P is appropriate, allowing the abutment part 17a to abut against the panel body P reliably.

[0018] The mounting configuration of the board material 14 and the mounting configuration of the horizontal airtight material 17 are similar not only on the lower rail material 13 side but also on the upper rail material 12 side as described above, and details thereof will be omitted by referencing the above explanation, but on the lower rail material 13 side, before the lower mounting piece member 15a is attached to the lower rail material 13 via the screw 15ad, the vertical height of the mounting piece member 15a is adjusted by the height adjustment member 16 provided on the lower rail material 13, and further the guide rail 6 is provided on the horizontal piece portion 15ba of the auxiliary piece member 15b. In contrast to this, the upper mounting piece member 15a attached to the upper rail material 12 side via the screw 15ad is configured so that the vibration stopper 4 is attached and fixed to the bottom piece portion 15ac of the mounting piece member 15a together with the horizontal piece portion 15ba of the auxiliary piece member 15c via the screw 15bc, and in these respects the upper and lower mounting piece members 15a differ.

[0019] In addition, for the left and right vertical frames 2, vertically oriented board material 19 is attached via board material attachment portions 20, but in this embodiment, the body side wing piece portion 3a of the hinge 3 is attached to the left and right inner piece portion 2a of the left and right vertical support pillars 2, and the panel body side wing piece portion 3b is attached to the door tail side vertical frame material 10 of the first panel body P1, and an L-shaped mounting bracket 2b is fixed with a screw to the left and right inner piece portion 2a of the left and right vertical support pillars 2, and an integrated inner mounting piece member 20a is attached via a screw 20b.This point differs from the case where the first and second inner piece portions 15ab, 15bb are used as separate members to cover the panel body side surface 14a of the horizontally oriented board material 14 described above, but the configuration is the same, and detailed explanation thereof will be omitted.

[0020] Furthermore, the board material mounting portion 20 for mounting the vertical board material 19 configured in this manner has a mounting groove 22 for the vertical airtight material for mounting the vertical airtight material 21, but the mounting groove 22 for the vertical airtight material is also formed in a configuration similar to that of the mounting groove 18 for the horizontal airtight material, and details thereof will be omitted. The vertically oriented airtight material 21 is attached by fitting the main body 21a into the mounting groove 22 for the vertically oriented airtight material, and the abutment portions 21b protruding from the main body 21a abut against the rear surface of the panel body P in a state of elastic deformation to provide airtightness, and the abutment portions 21b have a semicircular arc shape extending from both the left and right end edges of the main body 21a. Furthermore, the vertically oriented airtight material 21 is also provided with a plurality of removable adjustment pieces 21c to adjust the insertion depth of the main body 21a into the mounting groove 22 for the vertically oriented airtight material.

[0021] Next, the structure of the joining portion between the first panel body P1 and the second panel body P2, the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 will be explained. However, the structure of the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 is different from the structure of the joining portion between the first panel body P1 and the second panel body P2 in that it is the same as or is symmetrical to the structure of the joining portion between the first panel body P1 and the second panel body P2. Therefore, only the structure of the joining portion between the first panel body P1 and the second panel body P2 will be explained, and detailed explanations of the structure of the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 will be omitted. A square cylindrical joint member 23 is arranged opposite the door-end side vertical frame member 10 of the second panel body P2, with a gap U in the left-right direction relative to the door-front side vertical frame member 11 of the first panel body P1.The joint member 23 has a concave groove-shaped airtight material groove 23b for the joint member, which opens on the side of the adjacent first panel body P1, formed in the corner portion on the storage space T side of the left-right end surface portion 23a facing the door-end side vertical frame member 11 of the first panel body P1.

[0022] The main body 24a of the airtight material 24 for the joint is fitted into the airtight material groove 23b for the joint, and the abutment portion 24b extending from the main body 24a is curved so as to bulge from the front corner of the main body 24a towards the first panel body P1, and is formed in a fin-like shape extending towards the rear, so that it elastically deforms and abuts against the front end face portion 11a in the direction of movement of the flat front end face portion 11a of the front end vertical frame member 11 of the first panel body P1 as it moves from front to rear to close. Furthermore, the abutment portion 24b abutting against the door front end surface portion 11a is configured so that it can be seen from the gap U between the joint portions on the storage space T side.

[0023] By configuring it in this manner, the airtight material groove 23b for the joint portion does not protrude in the front-to-back direction relative to the second panel body P2, that is, it is arranged in a state that fits within the thickness dimension of the front-to-back thickness of the second panel body P.As a result, the above-mentioned upper and lower horizontal airtight materials 17 are configured to be continuous in the left-to-right direction even at the joint portion of the first and second panel bodies P1 and P2 without being obstructed by the airtight material groove 23b for the joint portion. Incidentally, the airtight material 24 for the joint also has a main body 24a to which multiple removable adjustment pieces 24c are attached, and is configured so that the contact state of the contact portion 24b can be adjusted. In this embodiment, the joint airtight material 24 and the horizontal airtight material 17 have in common the fact that they have fin-shaped abutment portions 24b, 17b.

[0024] In this way, the upper and lower horizontal airtight materials 17 are arranged in a continuous state on the left and right without being obstructed by the airtight material groove 23b for the joint part, so that the upper and lower horizontal airtight materials 17 can be attached at the same position in the front-to-back direction as the left and right vertical airtight materials 21 and abut against the panel body P to exhibit airtightness, thereby simplifying the structure. In this case, the horizontal airtight material 17 and the vertical airtight material 21 butt against each other at the four corners, but as mentioned above, the abutting portion 17b of the horizontal airtight material 17 is fin-shaped and configured as a cantilever extending from one edge of the main body 17a, while the abutting portion 21b of the vertical airtight material 21 is configured as a double-supported protrusion from the main body 21a, so they have different shapes.If such a configuration were to be made, for example, such that the vertical airtight material 21 extends to the corner end and the horizontal airtight material 17 abuts against the vertical airtight material 21, gaps would be formed due to the different shapes of the abutting portions 17b and 21b, which would cause a loss of airtightness. Therefore, in this embodiment, the horizontal airtight material 17 is cut out while leaving the abutment portion 17b and the opening side piece 17aa of the main body portion 17a, and the V-shaped piece formed by the remaining abutment portion 17b and opening side piece 17aa is overlapped with the abutment portion 21b of the vertical airtight material 21, and the overlapping abutment portion 17b and opening side piece 17aa are both elastically deformed by the closing panel body P, thereby ensuring airtightness. In this case, both the upper and lower end edges of the vertical airtight material 21, the main body portion 21a and the abutment portion 21b, abut or closely face the horizontal piece portion 15ba of the auxiliary piece member 15b in the horizontal board material mounting portion 15, and the left and right end edges of the horizontal airtight material 17 abut against the left and right inner side surfaces of the vertical airtight material main body portion 21a due to the main body portion 17a being cut out, and the abutment portion 17b, together with the opening side piece portion 17aa that remains uncut, abut or closely face the vertical frame mounting piece portion 2ba of the mounting bracket 2b for mounting the vertical board material mounting portion 20 to the left and right vertical frames 2, which is designed to contribute to ensuring high airtightness at the end edge portions of each airtight material 17, 21.

[0025] Furthermore, a lock body 25a constituting the locking device 25 is provided on the vertical frame material on the door end side of the first panel body P1, and is configured so that the first panel body P1 in the closed position can be locked from the front side, but the lock rod 25b provided on the lock body 25a is configured so that it can be freely engaged and disengaged with the lock receiver body 25c provided on the mating member 23 by turning the key (not shown) inserted into the lock body 25a.

[0026] In the present embodiment configured as described above, the panel bodies P constituting the partition panel 1 that divides the interior space into a use space S and a storage space T in the front and rear are configured so that a first panel body P1 that moves to open and close in the front-rear direction, second and third panel bodies P2 and P3 that slide to open and close in the left-right direction, and a fourth panel body P4 that moves to open and close in the front-rear direction are adjacent to each other in a series on the left and right, and in the closed state, the gap U between the first and second panel bodies P1 and P2 and the third and fourth panel bodies P3 and P4 is When the joint is airtightly sealed using the joint airtight material 24 provided on the second and third panel bodies P2 and P3, the abutment portion 24b extending in the left and right directions from the main body 24a of the joint airtight material 24 will abut against the flat joint surface 11a of the door-end vertical frame material 11 of the first and fourth panel bodies P1 and P4.As a result, the abutment portion 24a can be arranged in the joint gap U in a visible state, allowing for optimal installation of the joint airtight material 24.

[0027] The abutting portion 24b of the arranged joint airtight material 24 can be seen from the gap U on the joint storage space T side when the panel body P is closed. As a result, the installation depth of the joint airtight material 24 in the joint airtight material groove 23b can be adjusted while visually checking the abutting state of the abutting portion 24b, improving workability. Moreover, when adjusting the installation depth of the joint airtight material 24, the main body 24a can be incorporated into the joint airtight material groove 23b so that the position in the left and right direction can be adjusted freely by peeling off the adjustment piece 24c as necessary, and the abutting state of the abutting portion 24b against the joint surface 11a can be easily adjusted.

[0028] Furthermore, the airtight material grooves 23b for the joint portion provided in the second and third panel bodies P2 and P3 are provided in a position that does not protrude in the front-to-rear direction from the second and third panel bodies P2 and P3, and is biased toward the storage space T, which is the closing direction of the first and fourth panel bodies P1 and P4.As a result, at the final stage when the first and fourth panel bodies P1 and P4 finish closing, the abutment portion 24b makes sliding contact with the joint surface portion 11a, accompanied by elastic deformation, thereby reducing wear due to sliding of the abutment portion 24b and achieving a longer lifespan. In this case, the abutment portion 24b of the airtight material 24 for the joint portion is formed in a fin-like shape that bulges out toward the first and fourth panel bodies P1 and P4, curving from the edge portion of the main body portion 24a on the usage space S side toward the storage space T side.As a result, the fin-like abutment portion 24b extends in a cantilevered manner along the closing movement direction of the first and fourth panel bodies P1 and P4, which swing back and forth, allowing the abutment portion 24b to abut smoothly against the joint surface portion 11a, thereby achieving a high airtight effect.

[0029] Furthermore, in this device, the airtightness of each joint between the first and second panel bodies P1, P2, between the second and third panel bodies P2, P3, and between the third and fourth panel bodies P3, P4 can be ensured by the joint airtight material 24, but the joint airtight material groove 23b for attaching the joint airtight material 24 is configured so that it does not protrude toward the storage space T side of the panel body P. As a result, the upper and lower horizontal airtight materials 17 provided on the upper and lower rail members 12, 13 to ensure airtightness of the upper and lower edge portions of the panel body P on the storage space T side can be provided as a continuous series on the left and right at the joints between each adjacent panel body P, thereby achieving even greater airtightness.

[0030] Furthermore, in this device, the tail end edge portions of the first and fourth panel bodies P1 and P4 are pivotally supported via hinges 3 on the left and right vertical frames 2, which are main body side members, so that they can be opened and closed freely, and the abutment portions 21b of the vertical airtight material 21 provided on the left and right vertical frames 2 abut against the tail end side portions of the first and fourth panel bodies P1 and P4 on the usage space T side, so that the first and fourth panel bodies P1 and P4 work together with the above-mentioned horizontal airtight material 17 to maintain the airtightness of both the upper and lower end edges and the tail end edge portions. In this case, at the corner where the edge portions of the horizontal airtight material 17 and the vertical airtight material 21 intersect, the main body portion 17a of the horizontal airtight material 17 is removed while leaving the abutment portion 17b, and the two airtight materials 17, 21 are arranged in a vertically overlapping state so that the main body portion 21a of the vertical airtight material 21 fits into the gap where the main body portion 17a was removed, while the abutment portion 17b at the location where the main body portion 17a of the horizontal airtight material 17 was removed is overlapped with the abutment portion 21b of the vertical airtight material 21.As a result, at the corner where the horizontal airtight material 17 and the vertical airtight material 21 intersect, the abutment portions 17b, 21b, which are arranged overlapping each other when the panel body P is closed, are elastically deformed in an overlapping state by the first and fourth panel bodies P1, P4, which close, so that high airtightness can be achieved even at the corner.
