[0008] According to the partition structure relating to the second aspect, by configuring the link section with a first link mechanism and a second link mechanism, there is no need to use a link arm with a long hole formed therein, and therefore the vertical dimensions of the link section can be kept compact. Furthermore, by locking the rotation of the first link mechanism, horizontal displacement of the seal member can be restricted.

DETAILED DESCRIPTION OF THE INVENTION

[0022] [First embodiment] The following describes the schematic configuration of a partition structure 1 according to a first embodiment of the present invention, using Figures 1 to 5. As shown in Figure 1, the partition structure 1 according to this embodiment is configured to be able to close an opening formed by a ceiling C, a floor F, a first wall W1, and a second wall W2. The partition structure 1 is used, for example, to divide spaces in offices, schools, hospitals, stores, etc. In this specification, the front side of the page in Figure 1 will be referred to as the front of the partition structure 1, and the left side in Figure 1 will be referred to as the left side of the partition structure 1.

[0023] The partition structure 1 according to this embodiment comprises a rail 2 attached to the ceiling C, a plurality of panel members P·P··· suspended from the rail 2 and movable along the rail 2, and an end panel 4 suspended from the rail 2 and closing the right end of the opening. The plurality of panel members P·P··· and the end panel 4 are connectable by abutting their side ends as shown in FIG. 1 . A pressing portion 4a extends from the right side of the end panel 4. The pressing portion 4a presses against the second wall body W2, thereby closing the right end of the partition structure 1.

[0024] In the partition structure 1 according to this embodiment, the multiple panel members P·P··· gathered on the right side are sequentially moved leftward along the rail 2 to be connected in a row as shown in FIG. 1. The leftmost panel member P abuts against the first wall body W1, and the right side of the rightmost panel member P is closed by the end panel 4, thereby dividing a space from the ceiling C to the floor F. As shown in FIG. 2, when the partition structure 1 is used to close the opening, the gaps between each panel member P and the rail 2 are closed by the upper closing portion 5 (see FIG. 4). Furthermore, the gaps between each panel member P and the floor F are closed by the lower closing portion 6 (see FIG. 5).

[0025] 2 and 3, the panel member P includes a suspension member 31, a panel main body 3, an upper closing portion 5, and a lower closing portion 6. Each of the components of the panel member P will be described below.

[0026] As shown in Figure 3, the suspension member 31 is a member that displaceably connects the panel main body 3 and the rail 2. The suspension member 31 has an upper roller 31a and a lower roller 31b that are rotatably supported on a support shaft 31c. The support shaft 31c is arranged with its axis oriented vertically. The upper roller 31a and the lower roller 31b are housed in a roller housing section 21 formed inside the rail 2 so that they can rotate horizontally. The upper roller 31a and the lower roller 31b of the suspension member 31 rotate inside the roller housing section 21 of the rail 2, thereby allowing the panel member P to be displaced along the rail 2.

[0027] The panel main body 3 is connected to the lower part of the suspension member 31 via a connecting part 32 and an upper frame support part 34. The panel main body 3 comprises an upper frame member 35, a glass plate 36, a lower frame member 37, and vertical frame members 7·7. The upper frame member 35 and an upper link support part 33 are connected to the upper frame support part 34. The upper frame member 35 forms a frame that supports the periphery of the glass plate 36. The upper link support part 33 supports an upper link part 51 that forms the upper blocking part 5.

[0028] The upper frame member 35, together with the lower frame member 37 and the two vertical frame members 7, 7, forms a frame body that supports the glass plate 36. In other words, as shown in Figures 2 and 3, the outer periphery of the glass plate 36, which is a rectangular panel, is held by the frame body made up of the upper frame member 35, the lower frame member 37, and the vertical frame members 7, 7.

[0029] The panel main body 3 in this embodiment has a double-glazed structure in which a pair of double-glazed glass panes, each consisting of two overlapping glass plates 36, 36, are provided in the thickness direction of the panel member P. A lower link support 39 is fixed to the lower frame member 37 via a lower frame support 38. The lower link support 39 supports a lower link 61 that constitutes the lower blocking portion 6.

[0030] In the partition structure 1 according to this embodiment, the panel member P includes an upper blocking portion 5 provided at the upper end of the panel main body 3. The upper blocking portion 5 blocks the gap between the panel main body 3 and the rail 2 when the panel members P are connected to block the opening.

[0031] 2 and 4, the upper blocking portion 5 includes an upper link portion 51 and an upper seal member 52. The upper seal member 52 is movable toward and away from one side end of the panel main body 3 (the left side in this embodiment, the same applies below), and closes the gap formed between the panel main body 3 and the rail 2 on the upper side. The upper link portion 51 connects the panel main body 3 and the upper seal member 52 so that the upper seal member 52 is separated from the panel main body 3 in the vertical direction when it is retracted to the other side end (the right side in this embodiment, the same applies below).

[0032] As described above, the upper link portion 51 is supported by the upper link support portion 33 and connects the upper link support portion 33 and the upper seal member 52 so as to be relatively displaceable. The upper seal member 52 comprises a cylindrical upper seal main body 52a and an upper abutting member 52b, which is an elastic member provided on the upper surface of the upper seal main body 52a. An upper pressing portion 52c is provided at the left end of the upper seal main body 52a, and an upper pressed portion 52d is provided at the right end of the upper seal main body 52a.

[0033] 2, the upper link portion 51 and the upper seal body 52a are housed inside the upper frame member 35 and are difficult to see from the outside. An upper frame seal member 35a is provided on the inner surface of the upper frame member 35. The outer surface of the upper seal body 52a is always in contact with the upper frame seal member 35a, thereby preventing foreign matter and dust from entering the interior of the upper frame member 35.

[0034] When no external force is applied to the upper blocking part 5, the upper link part 51 contracts, bringing the upper link support part 33 and the upper seal member 52 closer together as shown in Fig. 4(a). On the other hand, when force is applied to the upper seal member 52 from the left side, the upper link part 51 expands in the vertical direction, moving the upper seal member 52 away from the upper link support part 33 as shown in Fig. 4(b).

[0035] In the partition structure 1, when the panel members P are connected to close the opening, the left end of the panel member P moving from the right side is pressed against the right end of the panel member P located on the left side. At this time, the upper pressing portion 52c of the upper sealing member 52 provided on the right panel member P abuts against the upper pressed portion 52d of the upper sealing member 52 provided on the left panel member P, and receives a reaction force from the left side.

[0036] As a result, the upper seal member 52 moves away from the upper link support portion 33, and the upper contact member 52b comes into contact with the contacted portion 22 of the rail 2. In other words, the upper seal member 52 closes the gap between the panel member P and the rail 2.

[0037] On the other hand, when the right panel member P is displaced to the right and the panel members P·P are separated from each other, the upper link portion 51 is contracted by the elastic member. Then, as shown in FIG. 4(a), the upper link support portion 33 and the upper seal member 52 approach each other, and the upper seal member 52 is separated from the rail 2.

[0038] In the partition structure 1 according to this embodiment, the panel member P includes a lower blocking portion 6 provided at the lower end of the panel main body 3. The lower blocking portion 6 blocks the gap between the panel member P and the floor surface F when the panel members P are connected to block the opening.

[0039] 2 and 5, the lower blocking portion 6 includes a lower link portion 61 and a lower seal member 62. The lower seal member 62 is movable toward and away from one side end of the panel main body 3, and closes the gap formed between the panel main body 3 and the floor surface F below the panel main body 3. The lower link portion 61 connects the panel main body 3 and the lower seal member 62 so that the lower link portion 61 is spaced apart from the panel main body 3 in the vertical direction when the lower seal member 62 is retracted toward the other side end.

[0040] As described above, the lower link portion 61 is supported by the lower link support portion 39 and connects the lower link support portion 39 and the lower seal member 62 so as to be relatively displaceable. The lower seal member 62 comprises a cylindrical lower seal main body 62a and a lower abutting member 62b, which is an elastic member provided on the underside of the lower seal main body 62a. A lower pressing portion 62c is provided at the left end of the lower seal main body 62a, and a lower pressed portion 62d is provided at the right end of the lower seal main body 62a.

[0041] 2 and 3, the lower link portion 61 and the lower seal body 62a are housed inside the lower frame member 37 and are difficult to see from the outside. A lower frame seal member 37a is provided on the inner surface of the lower frame member 37. The outer surface of the lower seal body 62a is always in contact with the lower frame seal member 37a, thereby preventing foreign matter and dust from entering the interior of the lower frame member 37.

[0042] When no external force is applied to the lower blocking part 6, the lower link part 61 contracts, bringing the lower link support part 39 and the lower seal member 62 closer together, as shown in Fig. 5(a). On the other hand, when force is applied to the lower seal member 62 from the left side, the lower link part 61 expands in the vertical direction, moving the lower seal member 62 away from the lower link support part 39, as shown in Fig. 5(b).

[0043] In the partition structure 1, when the panel members P are connected to close the opening, the left end of the panel member P moving from the right side is pressed against the right end of the panel member P located on the left side. At this time, the lower pressing portion 62c of the lower sealing member 62 provided on the right panel member P abuts against the lower pressed portion 62d of the lower sealing member 62 provided on the left panel member P and receives a reaction force from the left side.

[0044] As a result, the lower seal member 62 moves away from the lower link support portion 39, and the lower contact member 62b comes into contact with the floor surface F. That is, the gap between the panel member P and the floor surface F is closed by the lower seal member 62.

[0045] On the other hand, when the right panel member P is displaced to the right and the panel members P·P are separated from each other, the lower link portion 61 is contracted by the elastic member. Then, as shown in FIG. 5(a), the lower link support portion 39 and the lower seal member 62 approach each other, and the lower seal member 62 is separated from the floor surface F.

[0046] As described above, according to the partition structure 1 of this embodiment, when the opening is blocked by each panel member P, the gap between the panel member P and the rail 2 is blocked by the upper blocking portion 5, and the gap between the panel member P and the floor surface F is blocked by the lower blocking portion 6, thereby preventing sound and light leakage between the partitioned spaces.

[0047] [Lower obstruction part 6] Next, the detailed configuration of the lower blocking section 6 in the partition structure 1 according to this embodiment will be described with reference to Figures 6 to 9. Note that the upper blocking section 5 has a configuration that is substantially the same as the lower blocking section 6, but is inverted upside down, and therefore a detailed description of the upper blocking section 5 will be omitted.

[0048] In the partition structure 1 of this embodiment, the lower link portion 61 of the lower blocking portion 6 is equipped with a first link mechanism that connects the lower sealing member 62 to the panel main body portion 3 so that it can move forward and backward, and a second link mechanism that connects the lower sealing member 62 and the panel main body portion 3 so that they can move closer together and away from each other in the vertical direction.

[0049] 6, the first link mechanism in this embodiment is configured as a main link 64 whose base end is rotatably supported by the panel main body 3. The second link mechanism is configured as an adjustment link 67 whose base end is rotatably supported by the lower seal member 62.

[0050] 6, the main link 64 is a member formed in a substantially L-shape when viewed from the front. A main link support 63 is fixed to the lower link support 39. A base end portion on the right side of the main link 64 is supported rotatably on the first rotation axis A1 relative to the main link support 63. In other words, the main link 64 is rotatably supported on the panel main body 3 via the main link support 63.

[0051] 6, the adjustment link 67 is a member formed in a generally L-shape when viewed from the front. An adjustment link support portion 66 is fixed to the lower seal body 62a. A base end portion on the right side of the adjustment link 67 is supported rotatably on the fourth rotation axis A4 relative to the adjustment link support portion 66. In other words, the adjustment link 67 is rotatably supported by the lower seal member 62 via the adjustment link support portion 66.

[0052] The main link 64 and the adjustment link 67 are rotatably connected at their respective tip ends around a seventh rotation axis A7. It is also possible to configure the main link 64 and the adjustment link 67 to be connected at their midpoints.

[0053] The main link 64 is biased by a first spring S1, which is a first elastic member, in a rotation direction in which the lower seal member 62 extends toward one side end of the panel main body 3. Specifically, as shown in Fig. 6, a first spring support part 65 is rotatably supported by the main link support part 63 on a second rotation shaft A2. The second rotation shaft A2 is inserted through the first spring support part 65 in a displaceable manner inside a first elongated hole 65a that opens at the base end part on the right side of the first spring support part 65.

[0054] Furthermore, the vicinity of the base end of the main link 64 is rotatably connected to the tip end of the first spring support portion 65 by the third rotation axis A3. A first spring S1, which is a compression spring, is interposed between the second rotation axis A2 and the third rotation axis A3, so that the main link 64 is biased in a direction (clockwise direction) that causes the lower seal member 62 to extend leftward. In this way, the main link 64 constituting the first link mechanism is biased by the first spring S1, which is a first elastic member, in a rotation direction in which the lower seal member 62 extends toward one side end of the panel main body 3.

[0055] The adjustment link 67 is biased by a second spring S2, which is a second elastic member, in a rotation direction in which the lower seal member 62 moves downward away from the panel main body 3. Specifically, as shown in Figure 6, a second spring support part 68 is rotatably supported by the adjustment link support part 66 on a fifth rotation shaft A5. The fifth rotation shaft A5 is inserted through the second spring support part 68 in a displaceable manner inside a second elongated hole 68a that opens at the base end part on the right side of the second spring support part 68.

[0056] Furthermore, the vicinity of the base end of the adjustment link 67 is rotatably connected to the tip end of the second spring support portion 68 by the sixth rotation axis A6. Then, by inserting the second spring S2, which is a compression spring, between the fifth rotation axis A5 and the sixth rotation axis A6, the adjustment link 67 is biased in a direction (clockwise direction) that moves the lower seal member 62 downwardly away from the panel main body 3. In this way, the adjustment link 67 that constitutes the second link mechanism is biased by the second spring S2, which is a second elastic member, in the rotation direction that moves the lower seal member 62 downwardly away from the panel main body 3.

[0057] 5(a) and 6, when no external force is applied to the lower blocking portion 6, the main link 64 in the lower link portion 61 is biased by the first spring S1, causing the lower sealing member 62 to extend leftward. Meanwhile, the adjustment link 67 is biased by the second spring S2, causing the lower sealing member 62 to move downward away from the panel main body 3.

[0058] 5(b), 7(a), and 7(b), when a force is applied to the lower seal member 62 from the left side and the lower seal member 62 is displaced to the right, the main link 64 in the lower link portion 61 rotates counterclockwise against the biasing force of the first spring S1. As a result, the lower seal member 62 is displaced in the lower right direction, and the lower abutment member 62b abuts against the floor surface F. In other words, the gap between the panel member P and the floor surface F is closed by the lower seal member 62.

[0059] 7(a) shows a case where the distance between the panel main body 3 (lower link support portion 39) and the floor surface F is relatively large (this case will be referred to as "first sealing state"). During the first sealing state, as shown in FIG. 7(a), the adjustment link 67 remains biased by the second spring S2 (the same state as in FIG. 6), and the lower seal member 62 remains spaced downward from the panel main body 3.

[0060] On the other hand, as shown in Figure 8(a), when the distance between the panel main body 3 (lower link support portion 39) and the floor surface F is medium (this case will be described as "second sealing"), the lower sealing member 62 abuts against the floor surface F, applying a force from below to the lower sealing member 62, and the adjustment link 67 rotates counterclockwise against the biasing force of the second spring S2.

[0061] Furthermore, as shown in Figure 9, when the distance between the panel main body 3 (lower link support portion 39) and the floor surface F is relatively small (this case is described as "third sealing"), the lower seal member 62 abuts against the floor surface F more quickly, and the adjustment link 67 rotates further counterclockwise against the biasing force of the second spring S2.

[0062] In this way, in the partition structure 1 according to this embodiment, the adjustment link 67 constituting the second link mechanism is biased by the second spring S2, so that the lower seal member 62 moves downward away from the panel main body 3. As a result, even when the distance between the panel main body 3 and the floor surface F varies, as in the first to third seal times shown in Figures 7 to 9, the lower seal member 62 is brought into close contact with the floor surface F, ensuring the ability to prevent sound and light leakage between spaces partitioned by the partition structure 1.

[0063] As described above, in the partition structure 1 according to this embodiment, the lower link portion 61 of the lower blocking portion 6 includes a first link mechanism that connects the lower seal member 62 to the panel main body 3 so that the lower seal member 62 can move toward and away from the panel main body 3, and a second link mechanism that connects the lower seal member 62 to the panel main body 3 so that the lower seal member 62 can move toward and away from the panel main body 3 in the up-down direction. The main link 64 that constitutes the first link mechanism is biased by a first spring S1, which is a first elastic member, in a rotational direction in which the lower seal member 62 extends toward one side end of the panel main body 3. The adjustment link 67 that constitutes the second link mechanism is biased by a second spring S2, which is a second elastic member, in a rotational direction in which the lower seal member 62 moves downwardly away from the panel main body 3.

[0064] According to the partition structure 1 of this embodiment, as described above, the lower link portion 61 is composed of the main link 64, which is the first link mechanism, and the adjustment link 67, which is the second link mechanism, so there is no need to use a link arm with a long hole formed therein as in the prior art. In other words, since there is no need to ensure the vertical dimension when the link arm is oriented vertically, the vertical dimension of the lower link portion 61 can be kept compact.

[0065] Furthermore, according to the partition structure 1 of this embodiment, the main link 64 and the adjustment link 67 are respectively provided with a first spring S1 as a first elastic member and a second spring S2 as a second elastic member. This makes it possible to adjust the biasing force independently in the main link 64 as the first link mechanism and the adjustment link 67 as the second link mechanism.

[0066] Furthermore, in the partition structure 1 according to this embodiment, when the main link 64, which is the first link mechanism, rotates by a predetermined angle or more against the biasing force of the first spring S1, the first spring S1 biases the lower sealing member 62 in a rotational direction such that it retreats to the right side, which is the other end side.

[0067] 7(a), 8(a), and 9, when the third rotation axis A3 connecting the main link 64 and the first spring support portion 65 moves upward above the line connecting the first rotation axis A1 and the second rotation axis A2 (passes the pivot point) due to counterclockwise rotation of the main link 64, the first spring S1 applies a biasing force to the main link 64 in the counterclockwise rotation direction. As a result, a force is applied to the lower seal member 62 in a direction to retract to the right. In this embodiment, the main link 64 abuts against the main link support portion 63, thereby restricting further counterclockwise rotation.

[0068] As described above, in the partition structure 1 according to this embodiment, when the main link 64 rotates by a predetermined angle or more, the biasing force of the first spring S1 prevents the lower seal member 62 from naturally extending to the left side, which is one side end. That is, in this embodiment, the horizontal displacement of the lower seal member 62 is restricted by locking the rotation of the main link 64, which is the first link mechanism.

[0069] In the partition structure 1 according to this embodiment, the user can unlock the rotation of the main link 64 by pulling and displacing the panel member P to the right. When the user displaces the panel member P to the right, the lower seal member 62 tends to remain in place due to friction with the floor surface F. As a result, a clockwise force is applied to the main link 64, and as shown in FIG. 8(b), the rotation angle of the main link 64 becomes less than a predetermined angle, and the third rotation axis A3 is displaced below the line connecting the first rotation axis A1 and the second rotation axis A2. As a result, the rotation lock of the main link 64 is unlocked, and the main link 64 is biased by the first spring S1 in a rotation direction in which the lower seal member 62 extends to the left, which is one side end.

[0070] In the partition structure 1 according to this embodiment, the panel member P includes a lower frame member 37 that houses the lower link portion 61, as shown in Figure 3. The lower seal member 62 is movable toward and away from the lower frame member 37. In this manner, in this embodiment, the lower link portion 61 is covered by the lower frame member 37, thereby improving the aesthetic appeal of the panel member P. The upper link portion 51 is housed in the upper frame member 35, thereby improving the aesthetic appeal of the panel member P.

[0071] As described above, in this embodiment, it is possible to compactly reduce the vertical dimensions of the upper link portion 51 and the lower link portion 61 housed in the upper frame member 35 and the lower frame member 37. In the partition structure 1, the panel member P is configured such that the upper frame member 35 and the lower frame member 37 support the glass plate 36, and therefore in this embodiment, it is possible to compactly reduce the vertical dimensions of the upper frame member 35 and the lower frame member 37 that support the glass plate 36, thereby improving the aesthetic appearance of the panel member P.

[0072] [Second embodiment] Next, a partition structure according to a second embodiment of the present invention will be described with reference to Figures 10 and 11. The partition structure according to this embodiment differs from the partition structure according to the first embodiment in the configuration of the lower blocking portion 106, which corresponds to the lower blocking portion 6 of the partition structure 1 according to the first embodiment. Therefore, the following description will focus on the configuration of the lower blocking portion 106, and detailed description of the configuration common to the first embodiment will be omitted.

[0073] In the partition structure according to this embodiment, an upper blocking portion is provided which corresponds to the upper blocking portion 5 of the partition structure 1 in the first embodiment. The upper blocking portion according to this embodiment has a substantially similar configuration to the lower blocking portion 106, which is inverted upside down, and therefore a detailed description thereof will be omitted.

[0074] 10(a) and 10(b), the lower blocking portion 106 includes a lower link portion 161 and a lower seal member 162. The lower seal member 162 is movable toward and away from one side end of the panel main body 3, and closes the gap formed between the panel main body 3 and the floor surface F below the panel main body 3. The lower link portion 161 connects the panel main body 3 and the lower seal member 162 so that when the lower seal member 162 is retracted toward the other side end, it is spaced apart from the panel main body 3 in the vertical direction.

[0075] The lower seal member 162 comprises a cylindrical lower seal main body 162a and a lower abutting member 162b, which is an elastic member provided on the underside of the lower seal main body 162a. A lower pressing portion 162c is provided at the left end of the lower seal main body 162a, and a lower pressed portion 162d is provided at the right end of the lower seal main body 162a. The configuration of the lower seal member 162 is similar to that of the lower seal member 62 in the above embodiment, and therefore a detailed description thereof will be omitted.

[0076] The lower link portion 161 of the lower blocking portion 106 includes a first link mechanism that connects the lower seal portion 162 to the panel main body portion 3 so that the seal portion 162 can move forward and backward, and a second link mechanism that connects the lower seal member 162 to the panel main body portion 3 so that the seal portion 162 can move closer to and away from the panel main body portion 3 in the vertical direction.

[0077] 10, in the first link mechanism of this embodiment, the base ends of a connecting body U of a plurality of link members are rotatably supported by the panel main body 3, and the tip ends of the connecting body U are rotatably supported by the lower seal member 162. In addition, in the second link mechanism, the connecting body U can be extended or contracted by the relative rotation of the plurality of link members that make up the connecting body U.

[0078] 11(a) to 11(c), the connecting body U is configured by four link members, namely, a first link 164, a second link 165, a third link 166, and a fourth link 167, which are rotatably connected to one another about a first rotation axis B1, a second rotation axis B2, a third rotation axis B3, and a fourth rotation axis B4. In this embodiment, a panel-side support part 163 is fixed to the lower link support part 39. A base end portion on the upper right side of the connecting body U is rotatably supported by the panel-side support part 163 about the first rotation axis B1. In other words, the base end portion of the connecting body U is rotatably supported by the panel main body part 3 via the panel-side support part 163.

[0079] An arc-shaped hole 163a is formed in the panel-side support portion 163, and a second rotation shaft B2 that connects the first link 164 and the third link 166 is inserted into this arc-shaped hole 163a. ​​This allows the connecting body U to rotate around the first rotation shaft B1 while the second rotation shaft B2 is displaced inside the arc-shaped hole 163a.

[0080] Meanwhile, a seal-side support part 169 is fixed to the lower seal main body 162a. The tip of the connecting body U is rotatably supported by the seal-side support part 169 at a fourth rotation axis B4. In other words, the tip of the connecting body U is rotatably supported by the lower seal member 162 via the seal-side support part 169.

[0081] 11, a spring support portion 168 is rotatably supported by a fifth rotation shaft B5 on the panel side support portion 163. The fifth rotation shaft B5 is inserted through the spring support portion 168 so as to be displaceable inside an elongated hole 168a that opens at the base end of the spring support portion 168.

[0082] Additionally, an end of the fourth link 167 is rotatably connected to the tip of the spring support portion 168 by a sixth rotation shaft B6. A third spring S3, which is a compression spring, is inserted between the fifth rotation shaft B5 and the sixth rotation shaft B6, so that the connecting body U is biased in a direction that extends the lower seal member 162 to the left (clockwise direction).

[0083] As described above, in the first link mechanism of this embodiment, the base end of the connecting body U of the multiple link members is rotatably supported by the panel main body 3, and the tip end of the connecting body U is rotatably supported by the lower seal member 162. The third spring S3, which is an elastic member, biases the lower seal member 162 in a rotational direction in which it extends toward one side end of the panel main body 3.

[0084] In addition, in the second link mechanism of this embodiment, the plurality of link members constituting the connecting body U rotate relative to one another, thereby enabling the connecting body U to expand and contract. Specifically, as shown in FIGS. 11(b) and 11(c), the first link 164 to the fourth link 167 rotate relative to one another, thereby enabling the connecting body U to expand and contract in the vertical direction. Furthermore, the connecting body U is biased by a third spring S3, which is an elastic member, in a rotation direction in which the lower seal member 162 moves downwardly away from the panel main body 3. Specifically, as shown in FIG. 11(b), the connecting body U is biased by the third spring S3 in a direction in which the lower seal member 162 moves downwardly away from the panel main body 3 (a direction in which the connecting body U expands vertically).

[0085] As shown in Figures 10(a) and 11(a), when no external force is applied to the lower blocking portion 106, the connecting body U in the lower link portion 161 is biased by the third spring S3, causing the lower sealing member 162 to extend to the left.

[0086] 10(b) and 11(b), when a force is applied to the lower seal member 162 from the left side and the lower seal member 162 is displaced to the right, the connecting body U in the lower link portion 161 rotates counterclockwise against the biasing force of the third spring S3. As a result, the lower seal member 162 is displaced in the lower right direction, and the lower abutting member 162b abuts against the floor surface F. In other words, the gap between the panel member P and the floor surface F is closed by the lower seal member 162.

[0087] 11(b) shows a case where the distance between the panel main body 3 (lower link support portion 39) and the floor surface F is relatively large (this case will be referred to as "fourth sealing state"). During the fourth sealing state, as shown in FIG. 11(b), the connecting body U is maintained in an extended state (the same state as FIG. 11(a)) by the third spring S3, and the lower sealing member 162 maintains a position spaced downward from the panel main body 3.

[0088] On the other hand, as shown in Figure 11(b), when the distance between the panel main body 3 (lower link support portion 39) and the floor surface F is relatively small (this case is described as the "fifth sealing"), the lower sealing member 162 abuts against the floor surface F earlier, and the connecting body U contracts against the biasing force of the third spring S3.

[0089] In this way, in the partition structure according to this embodiment, the connecting body U constituting the second link mechanism is biased by the third spring S3, so that the lower seal member 162 moves downward away from the panel main body 3. As a result, even when the distance between the panel main body 3 and the floor surface F is different, as in the fourth and fifth sealing periods shown in Figures 11(b) and 11(c), the lower seal member 162 is brought into close contact with the floor surface F, ensuring the ability to prevent sound and light leakage between spaces separated by the partition structure.

[0090] As described above, in the partition structure according to this embodiment, the first link mechanism has the base ends of the connecting body U of the multiple link members rotatably supported by the panel main body 3, and the tip ends of the connecting body U rotatably supported by the seal member 162. In addition, the second link mechanism allows the connecting body U to expand and contract by the relative rotation of the multiple link members that make up the connecting body U.

[0091] In this way, because the lower link portion 161 is made up of the first link mechanism and the second link mechanism, there is no need to use a link arm with a long hole formed therein as in the prior art. In other words, since there is no need to ensure the vertical dimension when the link arm is oriented vertically, the vertical dimension of the lower link portion 161 can be kept compact.

[0092] Furthermore, according to the partition structure of this embodiment, the first link mechanism and the second link mechanism can be integrally configured as a connecting body U, making it possible to easily perform the assembly work of the lower link portion 161.

[0093] Furthermore, in the partition structure according to this embodiment, when the first link mechanism rotates by a predetermined angle or more against the biasing force of the third spring S3, the third spring S3 biases the lower seal member 162 in a rotational direction such that it retreats to the right side, which is the other end side.

[0094] 11(a) and 11(b), when the sixth rotation axis B6 connecting the connecting body U and the spring support part 168 moves upward above the line connecting the first rotation axis B1 and the fifth rotation axis B5 (passes the pivot point) due to counterclockwise rotation of the connecting body U, the third spring S3 applies a biasing force in the counterclockwise rotation direction to the connecting body U. As a result, a force is applied to the lower seal member 162 in a direction that moves it to retract to the right.

[0095] As described above, in the partition structure according to this embodiment, when the connecting body U is rotated by a predetermined angle or more, the biasing force of the third spring S3 prevents the lower seal member 162 from naturally extending to the left side, which is one side end. That is, in this embodiment, the horizontal displacement of the lower seal member 162 is restricted by locking the rotation of the first link mechanism.

[0096] In the partition structure according to this embodiment, the user can also unlock the rotation of the first link mechanism by pulling and displacing the panel member P to the right. When the user displaces the panel member P to the right, the frictional force between the lower seal member 162 and the floor surface F tends to keep it in place. This applies a clockwise force to the connecting body U, causing the rotation angle of the connecting body U to fall below a predetermined angle, displacing the sixth rotation axis B6 below the line connecting the first rotation axis B1 and the fifth rotation axis B5. This unlocks the rotation of the first link mechanism, and the third spring S3 biases the connecting body U in a rotational direction such that the lower seal member 162 extends to the left, which is one side end.

[0097] [Variations] The above embodiment can be modified as appropriate as shown in the following modifications. Note that each modification described in this specification may be applied in combination with other modifications as long as no contradiction occurs.

[0098] In the partition structure according to the present invention, in addition to the glass panel configured like the panel member P in the above embodiment, it is possible to employ panel members configured from various materials, such as steel panels and resin panels. Furthermore, when a glass panel is employed as the panel member P, either a single glass panel or a double glass panel can be employed.

[0099] Furthermore, the link section configuration described in this embodiment can be configured not only to be provided on both the top and bottom sides of the panel member P, but also to be provided only on the top or bottom side of the panel member P. It is also possible to have different configurations for the link sections on the top and bottom sides of the panel member P. For example, it is possible to adopt the link section configuration according to the first embodiment for the top blocking section of the panel member P, and adopt the link section configuration according to the second embodiment for the bottom blocking section of the panel member P.

[0100] Furthermore, in the partition structure according to the present invention, it is possible to configure the first link mechanism so that its rotation is not locked, and a biasing force from the elastic member is always applied to the seal member. It is also possible for the panel member of the partition structure to not include a frame member. Furthermore, if the panel member includes a frame member, it is also possible for the link portion not to be housed in the frame member. [Explanation of symbols]
