Description

This disclosure relates to a partition structure that includes a panel body, a side blocking portion that blocks the side end of the panel body, and an upper and lower blocking portion that blocks the upper and lower sides of the panel body.

Conventionally, a configuration has been disclosed in which a side blocking portion that blocks the side end side of the panel main body and an upper and lower blocking portion that blocks the upper and lower sides of the panel main body are connected by a link mechanism housed inside the panel main body (see, for example, Patent Document 1).

JP 2018-3402 A

According to the partition structure described in Patent Document 1, if the upper and lower dimensions of the panels differ, the length of the link mechanism must be changed, which increases manufacturing costs. In addition, the side blocking portion and the upper and lower blocking portions must be connected by a link mechanism housed inside the panel main body, which makes assembly difficult. Therefore, the present disclosure aims to solve the above problems.

The partition structure according to the first aspect of the present invention comprises a rail attached to a ceiling and a panel member suspended from the rail and movable along the rail, the panel member comprising a panel main body, a side blocking portion attached to one side end of the panel main body, and an upper and lower blocking portion attached to the upper end and/or lower end of the panel main body, the side blocking portion comprising a side seal member that blocks a gap by moving toward and away from one side end of the panel main body, and a side link mechanism that allows the side seal member to move forward and backward, the upper and lower blocking portion comprising an upper and lower seal member that blocks a gap by moving toward and away from the upper side and/or lower side of the panel main body, and an upper and lower link mechanism that allows the upper and lower seal members to move forward and backward, the side link mechanism and the upper and lower link mechanism being linked via the side seal member.

According to the partition structure of the first aspect, by linking the side link mechanism and the upper and lower link mechanisms via a side seal member, it is not necessary to link the side blocking portion and the upper and lower blocking portion with a link mechanism. Therefore, even if the upper and lower dimensions of the panel members are different, there is no need to change the length of the link mechanism, making it possible to reduce manufacturing costs. In addition, by linking the side blocking portion and the upper and lower blocking portions via a side seal member, it is possible to improve the ease of assembly of the side blocking portion and the upper and lower blocking portions.

In the partition structure according to the first aspect, the upper and lower blocking portions can be provided at either the upper end or the lower end of the panel main body, or at both ends.

The partition structure according to the second aspect of the present invention is the partition structure according to the first aspect, in which the upper and lower seal members can move forward and backward in accordance with the forward and backward movement of the side seal members.

According to the partition structure relating to the second aspect, it is possible to advance and retreat the upper and lower seal members by manipulating the advance and retreat of the side seal members.

The partition structure according to the third aspect of the present invention is the partition structure according to the second aspect, in which the advancing movement of the upper and lower seal members is initiated midway through the advancing movement of the side seal members.

The partition structure according to the third aspect makes it possible to start the advancing movement of the side seal members before the advancing movement of the upper and lower seal members.

The partition structure according to the fourth aspect of the present invention is a partition structure according to any one of the first to third aspects, in which the lateral link mechanism and the upper and lower link mechanisms are each integrally constructed.

The partition structure according to the fourth aspect described above makes it possible to improve the assembly of the side blocking parts and the upper and lower blocking parts.

The partition structure according to the fifth aspect of the present invention is a partition structure according to any one of the first to fourth aspects, and includes a corner seal member that moves toward one side end of the panel main body in accordance with the advancement and retreat of the side seal member, and moves toward the upper and/or lower side of the panel main body in accordance with the advancement and retreat of the upper and lower seal members.

The partition structure according to the fifth aspect makes it possible to close the corners formed in the gaps between the side seal members and the upper and lower seal members with corner seal members.

The partition structure of the present invention described above has the following advantages:

The partition structure according to the first aspect can reduce manufacturing costs and improve the ease of assembly of the side blocking sections and the upper and lower blocking sections.

The partition structure according to the second aspect can improve operability.

The partition structure according to the third aspect can improve the sealing function.

The partition structure according to the fourth aspect can improve the assembly of the side blocking parts and the upper and lower blocking parts.

According to the partition structure of the fifth aspect, the corners formed in the gaps between the side seal members and the upper and lower seal members can be closed with corner seal members.

[Partition structure 1]
A schematic configuration of a partition structure 1 according to one embodiment of the present invention will be described below with reference to Figures 1 and 2. The partition structure 1 according to this embodiment is configured to be capable of closing an opening formed by a ceiling on which a rail 2 is provided, a floor surface F, and a wall body W. The partition structure 1 is used, for example, to divide spaces in offices, schools, hospitals, stores, etc. In this specification, the lower right side in Figures 1 and 2 will be described as the front of the partition structure 1, and the lower left side in Figures 1 and 2 will be described as the left side of the partition structure 1.

The partition structure 1 according to this embodiment comprises a rail 2 and panel members (multiple continuous panels 3, 3... and one end panel 4) that are suspended from and movable along the rail 2. The multiple continuous panels 3, 3... and the end panel 4 are abutted against each other at their side ends so that they can be connected. Furthermore, when the multiple continuous panels 3, 3... and the end panel 4 are released from each other's connection, they can be stacked in the thickness direction and stored by moving sequentially to the right along the rail 2.

As shown in FIG. 3, the end panel 4 comprises a panel main body 41, a side blocking portion 5, an upper blocking portion 6, a lower blocking portion 7, an upper corner blocking portion 8, and a lower corner blocking portion 9. The side blocking portion 5 is provided at the right end portion of the panel main body 41. The upper blocking portion 6 and the lower blocking portion 7 are provided at the upper and lower ends of the panel main body 41, respectively, as one embodiment of the upper and lower blocking portions according to the present invention.

The upper corner blocking portion 8 is an embodiment of the corner seal member according to the present invention, and is provided so as to be able to block the upper side of the side blocking portion 5 and the right side of the upper blocking portion 6. The lower corner blocking portion 9 is an embodiment of the corner seal member according to the present invention, and is provided so as to be able to block the lower side of the side blocking portion 5 and the right side of the lower blocking portion 7.

In the partition structure 1 according to this embodiment, the side blocking portion 5, upper blocking portion 6, lower blocking portion 7, upper corner blocking portion 8, and lower corner blocking portion 9 can move forward and backward in both the lateral and vertical directions from the panel main body portion 41 of the end panel 4 (see Figures 3 to 12). When each of the blocking portions 5 to 9 is extended to block the periphery of the panel main body portion 41, the end panel 4 in the partition structure 1 is in a closed state as shown in Figure 1. On the other hand, when each of the blocking portions 5 to 9 is retracted to open the periphery of the panel main body portion 41, the end panel 4 in the partition structure 1 is in an open state as shown in Figure 2.

In the partition structure 1, the upper and lower sides of each continuous panel 3 can be closed by a closing member (not shown). In this way, the upper and lower sides of the continuous panel 3 are closed by the closing member, and the end panel 4 is closed as shown in FIG. 1, so that the opening formed by the ceiling, floor surface F, and wall body W is closed by the partition structure 1.

[Side blocking portion 5]
3 and 4, in the partition structure 1 according to this embodiment, the side blocking portion 5 includes a side seal member 5S and a side link mechanism 5L. The side seal member 5S closes the gap on the right side of the end panel 4 by advancing and retreating toward the right end side of the panel main body 41. The side link mechanism 5L is operated by a user of the partition structure 1 to allow the side seal member 5S to advance and retreat.

As shown in FIG. 4, the side link mechanism 5L is provided as an integrally assembled unit inside the panel main body 41, in which the side link base 50, guide member 51, operating member 52, first link members 53/53, second link members 54/54, side springs 55/55, support link members 56/56, and rotating link members 57/57 are arranged symmetrically in the vertical direction.

The side link base 50 is a plate-shaped member with a longitudinal direction in the vertical direction, and is fixed to the inner surface at the right end of the panel main body 41. The side link mechanism 5L is fixed integrally to the panel main body 41 via the side link base 50. A plate-shaped guide member 51 is fixed to the vertical center of the side link base 50. A semicircular groove-shaped guide hole 51a is formed in the guide member 51.

The center of the operating member 52 is rotatably attached to the guide member 51. An operating hole 52a is opened in the center of the operating member 52. The operating member 52 is positioned so that the operating hole 52a is in the same position as the operating hole 4a (see Figures 1 and 2) opened in the panel main body 41. A user of the partition structure 1 inserts the end of a handle (not shown) into the operating hole 52a via the operating hole 4a. The user then rotates the handle to rotate the operating member 52.

A guide protrusion 52b is formed on the back surface of the operating member 52, and when the operating member 52 is attached to the guide member 51, the guide protrusion 52b is inserted into the guide hole 51a. This restricts the rotation angle of the operating member 52 in the guide member 51 to within a range of 0 degrees to approximately 180 degrees clockwise (see Figures 3 and 11). In this embodiment, the initial state shown in Figure 3 (open state of the end panel 4) is described as "a state in which the rotation angle of the operating member 52 is 0 degrees."

The base ends of the first link members 53 (the lower end of the upper first link member 53 and the upper end of the lower first link member 53) are rotatably connected to both ends of the operating member 52. The first link member 53 is formed with a bent midway point.

The tip ends of the first link members 53, 53 are connected to the base ends of the second link members 54, 54 (the lower end of the upper second link member 54 and the upper end of the lower second link member 54) so as to be capable of relative rotation. As shown in FIG. 4, the connection between the first link member 53 and the second link member 54 is referred to as a first connection part P1. The first connection part P1 is slidable along the longitudinal direction of the second link member 54. The second link member 54 is provided so as to be slidable in the vertical direction along the lateral link base 50.

The tip ends of the second link members 54 are connected to the base ends of the rotating link members 57 (the lower end of the upper rotating link member 57 and the upper end of the lower rotating link member 57) so as to be capable of relative rotation. As shown in FIG. 4, the connection between the second link member 54 and the rotating link member 57 is referred to as a second connection part P2. The second connection part P2 is slidable along the longitudinal direction of the second link member 54. The middle parts of the rotating link members 57 are connected to the upper and lower ends of the side link base 50 by the support link members 56.

As shown in FIG. 4, a side spring 55, which is a compression spring, is inserted between the first connecting portion P1 and the second connecting portion P2. The side spring 55 is arranged so that it is in a natural state when the rotation angle of the operating member 52 is 0 degrees as shown in FIG. 3. On the other hand, as shown in FIG. 4 etc., when the rotation angle of the operating member 52 increases, the side spring 55 is compressed in the vertical direction. As a result, the side spring 55 biases the first connecting portion P1 and the second connecting portion P2 in a direction in which the first connecting portion P1 and the second connecting portion P2 move away from each other.

The side seal member 5S is provided at the tip of the rotating link members 57, 57 of the side link mechanism 5L. Specifically, the side seal member 5S is configured by integrally combining a side seal frame 58 provided inside the side panel 5P and a side seal portion 59 provided at the right end of the side panel 5P. The side seal portion 59 abuts against the wall body W when the end panel 4 is in the closed state. The tip of the rotating link members 57, 57 is rotatably connected to the side seal frame 58, whereby the side seal member 5S is assembled to the side link mechanism 5L.

In the side link mechanism 5L configured as described above, when the user uses the handle to rotate the operating member 52 clockwise by approximately 180 degrees, as shown by the arrow R in FIG. 4, the first link members 53 are displaced toward their respective tips (in the direction away from each other). This causes the second link members 54 to slide away from each other, and the base ends of the rotating link members 57 are displaced toward the upper and lower ends of the side link base 50. For this reason, as shown in FIG. 7, FIG. 9, and FIG. 11, the rotating link members 57 are rotated in a direction that increases the angle from the side link base 50, and the tips of the rotating link members 57 are displaced to the right, away from the side link base 50.

As the tips of the rotating link members 57, 57 are displaced to the right, the side seal member 5S is extended to the right. This causes the side seal portion 59 to come into contact with the wall body W, and the gap on the right side of the end panel 4 is blocked by the side blocking portion 5. At this time, the side seal portion 59 receives a reaction force from the wall body W toward the left side. As a result, the tips of the rotating link members 57, 57 are pushed back to the left side, and the rotating link members 57, 57 are rotated and displaced in a direction that reduces the angle from the side link base 50, and the side springs 55, 55 are compressed.

On the other hand, when the user rotates the operating member 52 counterclockwise using the handle, the first link members 53, 53 are displaced in a direction approaching each other. As a result, the rotating link members 57, 57 are rotated and displaced via the second link members 54, 54 in a direction that reduces the angle from the side link base 50, and the tips of the rotating link members 57, 57 are displaced to the left approaching the side link base 50. In other words, the side seal member 5S retreats to the left, so the side seal portion 59 moves away from the wall body W, and the gap on the right side of the end panel 4 is opened.

When the right side of the end panel 4 is blocked by the side blocking portion 5, the first link members 53, 53 are biased by the side springs 55, 55 in a direction toward each other as shown in FIG. 11. At this time, the operating member 52 has rotated to a position where the connection between the operating member 52 and the first link members 53, 53 exceeds the center of rotation of the operating member 52 (exceeds the fulcrum). Therefore, a force is applied to the operating member 52 by the biasing force of the side springs 55, 55 via the first link members 53, 53 in a direction that increases the rotation angle (clockwise direction). In other words, the operating member 52 does not naturally return to its original state of a rotation angle of 0 degrees, so the blocking state by the side blocking portion 5 is maintained.

[Upper blocking portion 6]
As shown in Figures 3, 5 and 6, in the partition structure 1 according to this embodiment, the upper blocking portion 6 comprises an upper seal member 6S and an upper link mechanism 6L. The upper seal member 6S closes the gap above the end panel 4 by advancing and retreating above the panel main body portion 41. The upper link mechanism 6L allows the upper seal member 6S to advance and retreat in conjunction with the advance and retreat of the side seal member 5S. Note that the lower blocking portion 7 (lower seal member 7S and lower link mechanism 7L) is configured in the same manner as the upper blocking portion 6 described below, and therefore a detailed description of the lower blocking portion 7 will be omitted.

As shown in Figures 5 and 6, the upper link mechanism 6L is provided inside the panel main body 41 as an integrally assembled unit in which the upper link base 60, rotating link members 61, roller support members 62, guide rollers 63, slide link members 64, upper springs 65, and upper seal connecting member 66 are arranged symmetrically in the left-right direction.

The upper link base 60 is a plate-like member fixed to the inner surface at the upper end of the panel main body 41, and the upper link mechanism 6L is fixed integrally to the panel main body 41 via the upper link base 60. A support piece 60a bent forward is formed at the lower end of the upper link base 60. A first guide hole 60b is opened in the vertical direction at the center of the left-right direction of the upper link base 60, and a second guide hole 60c is opened in the vertical direction below the first guide hole 60b.

Plate-shaped rotating link members 61, 61 are provided symmetrically on the upper link base 60. Each rotating link member 61, 61 is rotatably supported on the upper link base 60 by a rotating shaft 61a provided in the middle. A long hole 61b is opened along the longitudinal direction at the inner end of each rotating link member 61, 61. As shown in FIG. 5, the long holes 61b, 61b of the rotating link members 61, 61 are arranged so as to overlap each other.

A roller support member 62 having a longitudinal direction in the vertical direction is connected to the rotating link members 61. A pin 62a is formed at the upper end of the roller support member 62, and the pin 62a is inserted into the long holes 61b of the rotating link members 61 and the first guide hole 60b of the upper link base 60. This allows the roller support member 62 to be slidably displaced in the vertical direction relative to the upper link base 60.

A guide roller 63 is rotatably mounted on the lower end of the roller support member 62. The roller support shaft 63a of the guide roller 63 is inserted into the second guide hole 60c of the upper link base 60. This allows the guide roller 63, together with the roller support member 62, to be slidably displaced in the vertical direction relative to the upper link base 60.

The lower ends of the slide link members 64/64 are connected to the outer ends of the respective rotating link members 61/61 so as to be rotatable relative to the rotating link members 61/61 and so as to be slidably displaced in the longitudinal direction of the rotating link members 61/61. A third connecting portion P3, which is a pin fixed to the upper link base 60, is inserted into a long hole opened in the slide link members 64/64. This allows the slide link members 64/64 to be slidably displaced in the vertical direction relative to the upper link base 60.

The upper end of the slide link members 64, 64 is connected to the upper seal connecting member 66 via the fourth connecting portion P4. An upper corner support portion 66a is provided on the upper surface of the upper seal connecting member 66.

In this embodiment, as shown in FIG. 5, upper springs 65, which are compression springs, are inserted between the third connecting portion P3 and the fourth connecting portion P4. The upper spring 65 is always compressed in the vertical direction, so it biases the third connecting portion P3 and the fourth connecting portion P4 in a direction in which the third connecting portion P3 and the fourth connecting portion P4 move away from each other.

The slide link members 64, 64 are displaced by the upward biasing force of the upper springs 65, 65. As a result, the rotating link members 61, 61 are rotated and displaced in a direction such that the inner ends face downward, and a downward force is constantly applied to the roller support member 62 and the guide roller 63.

The upper seal member 6S is connected to the upper seal connecting member 66 in the upper link mechanism 6L. Specifically, the upper seal member 6S is formed by integrally combining an upper seal support member 67 connected to the upper seal connecting member 66, a left end member 68 provided on the left end surface of the upper seal support member 67, and an upper seal portion 69 provided on the upper end surface of the upper seal support member 67. The upper seal portion 69 abuts against the rail 2 when the end panel 4 is in the closed state.

When the upper seal connecting member 66 in the upper link mechanism 6L is displaced upward, the upper seal member 6S is extended upward. This causes the upper seal portion 69 to come into contact with the rail 2, and the gap above the end panel 4 is blocked by the upper blocking portion 6. At this time, the upper seal portion 69 receives a downward reaction force from the rail 2. This causes the upper seal connecting member 66 to be pushed back downward, compressing the upper springs 65, 65.

In the partition structure 1 according to this embodiment, the side link mechanism 5L of the side blocking portion 5 and the upper link mechanism 6L of the upper blocking portion 6 are linked via a side seal member 5S. Specifically, as shown in Figs. 5 and 6, a support member 58a that protrudes to the left is provided on the upper portion of the side seal frame 58 of the side seal member 5S. A slide member 58b that extends to the left is rotatably connected to the support member 58a.

The slide member 58b is placed on the support piece 60a of the upper link base 60 and is slidable in the left-right direction along the support piece 60a. An abutment member 58c is fixed to the left end of the slide member 58b. A first abutment surface 58d is formed on the abutment member 58c as a horizontal surface formed at the upper end. To the left of the first abutment surface 58d, a second abutment surface 58e is formed as an inclined surface that slopes downward as it approaches the left side. To the left of the second abutment surface 58e, a third abutment surface 58f is formed as a horizontal surface formed at the lower end of the abutment member 58c.

In this embodiment, as shown in FIG. 5, the abutment member 58c is inserted between the support piece 60a and the guide roller 63 in the upper link mechanism 6L. As a result, the guide roller 63 is lifted upward while abutting against the first abutment surface 58d of the abutment member 58c, and the guide roller 63 and the roller support member 62 are displaced upward. As a result, the outer ends of the rotating link members 61 are rotated and displaced in a direction facing downward, and the sliding link members 64 are displaced downward against the biasing force received from the upper springs 65. In other words, the upper seal connecting member 66 in the upper link mechanism 6L is displaced downward, and the upper seal member 6S is retracted to the inside of the panel body portion 41 of the end panel 4.

In the partition structure 1 according to this embodiment, when the user uses the handle to rotate the operating member 52 clockwise and the side seal member 5S is extended to the right, the abutment member 58c is displaced to the right in turn (see Figures 8, 10, and 12). As a result, the guide roller 63 abuts against the second abutment surface 58e of the abutment member 58c, and is displaced downward as the abutment member 58c is displaced to the right. As a result, the rotating link members 61, 61 are rotated in a direction such that the inner ends face downward, and the sliding link members 64, 64 are displaced upward by the biasing force they receive from the upper springs 65, 65.

That is, the upper seal connecting member 66 of the upper link mechanism 6L is displaced upward, causing the upper seal member 6S to extend upward. As a result, the upper seal portion 69 comes into contact with the rail 2, and the gap above the end panel 4 is blocked by the upper blocking portion 6.

On the other hand, when the user rotates the operating member 52 counterclockwise using the handle, the upper seal connecting member 66 in the upper link mechanism 6L is displaced downward. In other words, the upper seal member 6S retreats downward, so the upper seal portion 69 moves away from the rail 2, and the gap above the end panel 4 is opened.

[Upper corner closure portion 8]
5 and 6, the partition structure 1 according to this embodiment includes an upper corner blocking portion 8, which is one embodiment of a corner seal member. The upper corner blocking portion 8 is a member that blocks the upper side of the side blocking portion 5 and the right side of the upper blocking portion 6, and is assembled to the side seal member 5S and the upper seal member 6S. Note that the lower corner blocking portion 9, which is a member that blocks the lower side of the side blocking portion 5 and the right side of the lower blocking portion 7 and is one embodiment of a corner seal member, is configured in the same manner as the upper corner blocking portion 8 described below, and therefore a detailed description thereof will be omitted.

As shown in Figures 5 and 6, the upper corner blocking section 8 is provided as a unit in which the upper corner base 80, roller support section 82, roller 83, upper buffer section 84, and side buffer section 85 are integrally combined.

The upper corner base 80 is a plate-shaped member that constitutes the main body of the upper corner closure part 8. The upper part of the upper corner base 80 is bent horizontally to form a mounting piece 81. A roller support part 82 that extends downward is provided at the right end of the upper corner base 80. Two rollers 83 are rotatably mounted on the roller support part 82. An upper buffer part 84 that abuts against the rail 2 is provided on the upper surface of the upper corner base 80. A side buffer part 85 that abuts against the wall body W is provided on the right side of the upper corner base 80.

As shown in FIG. 5, the upper corner base 80 is inserted into the upper seal support member 67 of the upper seal member 6S, and the mounting piece 81 is placed on the upper surface of the upper corner support portion 66a, allowing it to slide left and right. In addition, the roller support portion 82 and the roller 83 are inserted into the side seal frame 58 of the side seal member 5S, allowing it to be displaced up and down inside the side seal frame 58.

As described above, the upper corner blocking portion 8 is capable of moving relative to the side seal member 5S and the upper seal member 6S in a direction perpendicular to the direction of movement of the respective seal members 5S and 6S. As a result, the upper corner blocking portion 8 moves toward and away from the right end of the panel main body portion 41 in conjunction with the movement of the side seal member 5S, and moves toward and away from the upper side of the panel main body portion 41 in conjunction with the movement of the upper seal member 6S.

As shown in FIG. 12, when the side seal portion 59 abuts against the wall W and the gap on the right side of the end panel 4 is blocked by the side blocking portion 5, the side buffer portion 85 of the upper corner blocking portion 8 abuts against the wall W. Also, when the upper seal portion 69 abuts against the rail 2 and the gap on the upper side of the end panel 4 is blocked by the upper blocking portion 6, the upper buffer portion 84 of the upper corner blocking portion 8 abuts against the rail 2. In this way, when the end panel 4 is blocked, the upper corner blocking portion 8 blocks the upper side of the side blocking portion 5 and the right side of the upper blocking portion 6.

As described above, according to the partition structure 1 of this embodiment, the side link mechanism 5L in the side blocking portion 5 and the upper link mechanism 6L in the upper blocking portion 6 are linked via the side seal member 5S. This eliminates the need to provide a link mechanism for connecting the side link mechanism 5L and the upper link mechanism 6L, so that a common side link mechanism 5L and upper link mechanism 6L can be used even when the upper and lower dimensions of the end panel 4 are different. In other words, since there is no need to manufacture a link mechanism for each length dimension of the end panel 4, it is possible to reduce the manufacturing costs of the partition structure 1.

In addition, according to the partition structure 1 of this embodiment, the side link mechanism 5L and the upper link mechanism 6L are linked by a side seal member 5S that advances and retreats from the panel main body 41, which improves assembly ease compared to a configuration in which the link mechanism linking the side link mechanism 5L and the upper link mechanism 6L is housed inside the panel main body 41.

In addition, in the partition structure 1 according to this embodiment, the side link mechanism 5L and the upper link mechanism 6L are linked by the side seal member 5S, so that the upper seal member 6S can advance and retreat in conjunction with the advance and retreat movement of the side seal member 5S. This allows the user of the partition structure 1 to advance and retreat the upper seal member 6S by manipulating the advance and retreat of the side seal member 5S. In other words, the upper seal member 6S can be advanced and retreated simultaneously with the side seal member 5S.

In addition, in the partition structure 1 according to this embodiment, the advancing operation of the upper seal member 6S is started in the middle of the advancing operation of the side seal member 5S. Specifically, as shown in FIG. 5 and FIG. 8, even if the side seal member 5S is extended to the right side and the abutment member 58c is displaced to the right side, the guide roller 63 continues to abut against the first abutment surface 58d for a while, so that the upper seal member 6S continues to be retracted downward. Then, in the middle of the advancing operation of the side seal member 5S to the right side, the guide roller 63 abuts against the second abutment surface 58e, and the upper seal member 6S is extended upward. In this way, according to the partition structure 1, it is possible to start the advancing operation of the side seal member 5S before the advancing operation of the upper seal member 6S.

In addition, in the partition structure 1 according to this embodiment, the side link mechanism 5L and the upper link mechanism 6L are each provided as an integrally combined unit. This reduces the amount of labor required to construct the side blocking portion 5 and the upper blocking portion 6, thereby improving the ease of assembly of the side blocking portion 5 and the upper blocking portion 6 in the end panel 4. In addition, the side link mechanism 5L and the upper link mechanism 6L can be stocked in units, making inventory management easier and shortening lead times.

The partition structure 1 according to this embodiment also includes an upper corner blocking portion 8 as a corner seal member that moves toward and away from the right end of the panel main body 41 as the side seal member 5S moves forward and backward, and moves toward and away from the upper side of the panel main body 41 as the upper seal member 6S moves forward and backward. This makes it possible for the upper corner blocking portion 8 to block the corner formed in the gap between the side seal member 5S and the upper seal member 6S.

[Modification]
The above embodiment can be modified as appropriate as shown in the following modified examples. Each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

In the partition structure of the present invention, the upper and lower blocking portions (upper blocking portion 6 and lower blocking portion 7 in the above embodiment) can be configured to be provided at both the upper and lower ends of the panel main body portion 41 as in this embodiment, or they can be configured to be provided at either the upper or lower end of the panel main body portion.

It is also possible to configure the side seal members to advance and retreat in conjunction with the advance and retreat of the upper and lower seal members. In this case, the side seal members can be configured to begin advancing midway through the advancement of the upper and lower seal members.

In addition, it is also possible to configure the side link mechanism and the upper and lower link mechanism not as an integrated unit, but to assemble several parts at the work site. It is also possible to configure the partition structure without providing corner seal members that close the corners formed in the gaps between the side seal members and the upper and lower seal members.
