Description

The present invention relates to a partition panel with a door body that constitutes a mobile partition device for partitioning and using a room such as an office, a conference room, a showroom, or a store.

When the indoor space of an office, conference room, showroom, store, etc. is divided and used according to the purpose, partition panels that are movably suspended along rails fixed to the ceiling surface are connected. A moving partition device for partitioning into a predetermined section is used. In such a moving partition device, it is known that a partition panel with a door body is used at a predetermined position to enable traffic between two partitioned spaces (see Patent Document 1). ).

The partition panel with a door body shown in Patent Document 1 includes a door support portion extending vertically and a door body rotatably attached to the frame body by a hinge, and the lower part of the door body is closed. A member and a lower advancing / retreating mechanism for advancing / retreating the lower closing member are housed. The lower advancing / retreating mechanism includes a shaft extending to the left and right provided at the lower part of the door body, and two link mechanisms attached to two places on the left and right of the shaft. A lower closing member is suspended below the two link mechanisms. When the door body is operated in the closing direction, the shaft abuts on the side surface of the door support portion, and when the shaft is pushed horizontally toward the inside of the door body, the two link mechanisms extend downward and the lower part. The closing member descends to the floor surface to close the space between the door body and the floor surface. In other words, the regressive motion of the shaft is converted into the motion of lowering the lower closing member by the two link mechanisms. Thereby, the airtightness and sound insulation of the room can be improved.

Patent No. 3012571 (Page 3, Fig. 1)

As described above, in Patent Document 1, the two left and right link mechanisms operate with respect to the horizontal movement of the shaft, but these link mechanisms have the same structure as each other. Therefore, when the pressing portion is pressed when the door body is operated in the closing direction, the two link mechanisms are extended downward at the same timing. That is, the lower closing member descends in a horizontal posture, and the lowered lower closing member comes into contact with the floor surface in a wide range in the left-right direction. Therefore, in the process of changing the door body from the open state to the closed state, a large frictional resistance is suddenly generated at a certain point, and there is a possibility that the door body cannot be closed smoothly.

The present invention has been made by paying attention to such a problem, and can smoothly close the door body while having a lower closing member that descends with respect to the floor surface in conjunction with the closing operation of the door body. It is an object of the present invention to provide a partition panel with a door body.

In order to solve the above problems, the partition panel with a door body of the present invention is used.
It is suspended from a taxiway provided on the ceiling via a taxiway member and is connected so as to partition a space together with a plurality of partition panels that can move along the taxiway, and the moving partition device is configured together with the plurality of partition panels. And
The door body is rotatably attached to the door support portion suspended and supported via the suspension member, and is retracted by the lower closing member housed in the lower part of the door body and the closing operation of the door body. A partition panel with a door body, which is provided with a moving unit and a lower advancing / retreating mechanism for converting a retreating operation of the operating unit into an operation of lowering the lower closing member.
In the process of closing the door body, one side of the lower advancing / retreating mechanism in the left-right direction is pushed downward in advance of the other side.
According to this feature, the lower advancing / retreating mechanism is an operation in which a pressing force acts on the floor surface from one side to the other side in the left-right direction of the lower closing member in the process of closing the door body. In the process of the body changing from the open state to the closed state, a large frictional resistance does not suddenly occur at a certain point, and the door body can be smoothly closed.

The lower advancing / retreating mechanism is characterized in that the hanging side of the door body is pushed downward in advance of the door end side in the left-right direction of the lower closing member.
According to this feature, since the arm length from the rotation support shaft of the door body is short on the hanging side of the door body, it is not easily affected by the frictional resistance of the lower closing member, so that the hanging side of the lower closing member is the door. By contacting the floor surface prior to the front side, the door body is smoothly closed at the initial stage where the lower closing member comes into contact with the floor surface in the process of the door body changing from the open state to the closed state. Can be operated.

The displacement of the lower closing member by the lower advancing / retreating mechanism linked to the horizontal displacement of the retreating movement of the moving portion is characterized in that the displacement of the lower closing member on the hanging side is larger than that on the door end side. It is supposed to be.
According to this feature, when the moving part is regressed, the lower closing member descends toward the floor in an inclined state in which the hanging side is lower than the door end side, so that the door body is closed from the open state. In the initial stage where the lower closing member comes into contact with the floor surface in the process of becoming a state, the door body can be smoothly closed without being affected by the frictional resistance of the lower closing member.

The lower advancing / retreating mechanism includes link arms connected to the operating portion on the hanging side and the door end side, respectively, and the link arm on the hanging side is longer than the link arm on the door end side. It is said.
According to this feature, since the lower advancing / retreating mechanism is provided with two link arms having different lengths, the lower closing member can be lowered toward the floor surface in an inclined state with a simple structure.

It is characterized in that an urging means for always applying an urging force is interposed between the operating portion and the connection end of the link arm on the hanging side so as to be relatively separated from each other.
According to this feature, on the hanging side of the lower closing member that first comes into contact with the floor surface in the process of the door body from the open state to the closed state, the shrinkage of the urging means causes the link arm to pass through the lower closing member. The force acting on the floor surface is not excessive, and the door body can be closed smoothly.

By connecting the panel 1 and the partition panels 101, 101, ... In a row in the left-right direction (traveling direction), the interior space can be partitioned from the ceiling surface R to the floor surface F. Further, in the partition panel 101, the upper closing member 111 and the lower closing member 112, which will be described later, are pressed toward the rail 3 and the floor surface F, so that the blocking property of sound and light leakage is enhanced.

As shown in FIG. 2, the partition panel 101 is a four-sided frame-shaped frame member that integrally holds a pair of translucent panels 104, 104 arranged so as to face each other at a distance in the front and rear, and the translucent panels 104, 104. A 105 (upper frame 106, vertical frames 107, 107, and lower frame 108) is provided, and the frame member 105 is suspended from the rail 3 by suspension members 9 and 9. As the panel material, a translucent panel 104 such as glass having translucency is used, and it is possible to produce a feeling of openness in the interior space partitioned by the partition panel 101. The translucent panel 104 may be made of highly transparent polycarbonate or acrylic resin.

The upper frame 106 and the lower frame 108 include an upper closing member 111 and a lower closing member 112, and an upper advancing / retreating mechanism and a lower advancing / retreating mechanism (not shown) for advancing / retreating the upper closing member 111 and the lower closing member 112. ..

Next, the mobile partition panel 1 with a door body will be described with reference to FIG. The movable partition panel 1 with a door body includes a door support portion 2 having an inverted L shape and a door body 7 rotatably attached to the door support portion 2 by a gear hinge 5. The door body 7 is a four-sided frame-shaped frame member 72 (upper frame 73,) that integrally holds a pair of front and rear translucent panels 71, 71 such as glass and a pair of front and rear translucent panels 71, 71. A vertical frame 74, 74 and a lower frame 75) are provided to form a double glass panel structure.

The upper frame 73 is made of a metal such as aluminum and is formed in an upward U-shape by extrusion molding. An upper closing member and an upper advancing / retreating mechanism (not shown) are housed inside a groove 73a that opens upward. Has been done. Like the upper frame 73, the lower frame 75 is also formed in a downward U-shape by extrusion molding, and a lower advancing / retreating mechanism 20 for advancing / retreating the lower closing member 12 and the lower closing member 12 inside the groove portion 75a that opens downward. (See Fig. 4) and is housed. The lower closing member 12 is formed in an upward U-shape, and includes a groove portion 12a that opens upward. The upper frame 73 and the lower frame 75 are not limited to extrusion molding, and may be formed by, for example, bending a sheet metal or welding a sheet metal.

As shown in FIG. 5A, the gear hinge 5 includes two geared mounting plates 51 and 51, and the two geared mounting plates 51 and 51 are fixed to the door support portion 2 and the door body 7, respectively. ing. The gear hinge 5 is a long hinge that extends vertically over the upper and lower ends of the door body 7 (see FIG. 3). Further, by rotating the door body 7 counterclockwise on the paper surface, the door body 7 can be opened 180 degrees. A hinge having a form other than the gear hinge 5 may be used.

Next, with reference to FIG. 4, in a space formed between the groove portion 75a of the lower frame 75 of the door body 7 and the groove portion 12a of the lower closing member 12 (hereinafter, referred to as “lower space of the lower frame 75”). The lower advancing / retreating mechanism 20 to be accommodated will be described. Inside the lower space of the lower frame 75 of the door body 7, there are a shaft 18 which is an operating unit constituting the lower advancing / retreating mechanism 20, a guide member 19 which guides and supports the shaft 18 so as to be movable in the axial direction, and a first. The link mechanism 21 and the second link mechanism 22 are arranged.

As shown in FIG. 4, the guide member 19 includes a flange portion 19a extending in the front-rear direction of the door body 7, and the flange portion 19a has a screw or the like on the bottom surface of the lower frame 75 (see FIG. 3) of the door body 7. It is fixed with. Further, the guide member 19 includes a tubular portion 19b through which the shaft 18 is inserted, guides the shaft 18 in the axial direction with respect to the lower frame 75, and guides the shaft 18 to the hanging side (gear hinge 5 side) of the door body 7. It is supported by.

The tip 18a of the shaft 18 is arranged on the hanging side of the door 7, and when the door 7 is in the open state as shown in FIG. 5A, the tip 18a is the door 7. It is urged by a push spring 41 (see FIG. 4), which is an urging means described later, so that the portion excluding the tip portion 18a protrudes from the side end of the door to the door support portion 2 side and is arranged in the lower frame 75. There is. Then, when the door body 7 is rotated in the closing direction as shown in FIG. 5 (b), the tip portion 18a is pressed against the vertical frame 2a (see FIG. 3) of the door support portion 2, and the reaction force causes the tip portion 18a to be pressed against the vertical frame 2a (see FIG. 3). A part of the tip portion 18a of the shaft 18 is retracted into the lower frame 75.

A first link mechanism 21 is connected to the shaft 18 on the hanging side in the axial direction, and a second link mechanism 22 is connected to the door end side in the axial direction. Specifically, the first link mechanism 21 has a base portion 23 fixed to the lower frame 75 (see FIG. 3) of the door body 7, a link arm 24 having one end pivotally supported by the shaft 18, and one end. The interlocking arm 25 is pivotally supported by the base portion 23 and the other end is pivotally supported by the central portion in the longitudinal direction of the link arm 24, and the other end of the link arm 24 is pivotally supported by being fixed to the lower closing member 12. It is configured to include a base portion 27.

The link arm 24 and the interlocking arm 25 of the first link mechanism 21 form an inverted Y shape when viewed from the front, and the other end pivotally supported by the lower closing member 12 of the link arm 24 and the base of the interlocking arm 25. One end pivotally supported by the portion 23 is arranged so as to face the door end side. The second link mechanism 22 has the same structure.

A pair of interlocking arms 25 are provided so as to sandwich the shaft 18 in the width direction, and the shafts are formed on a pair of standing pieces 23a and 23a standing by sandwiching the shaft 18 in the downward U-shaped base portion 23 in the width direction, respectively. It is rotatably supported by a rotating shaft 30 inserted through elongated holes 181, 181 extending in the axial direction penetrating 18 in the width direction. Further, the rotating shaft 30 is movable in the axial direction in the elongated hole 181.

The pair of link arms 24, 24 arranged so as to sandwich the shaft 18 in the width direction are rotatable by a rotating shaft 31 inserted through elongated holes 182, 182 extending in the axial direction penetrating the shaft 18 in the width direction. It is supported. The rotating shaft 31 is movable in the axial direction in the elongated hole 182.

Further, the shaft 18 is formed to be hollow, and a push spring 40 as an urging means is arranged inside so that the shaft 18 can advance horizontally in the door support two directions and regress in the lower frame 75 direction. ing. The push spring 40 includes a rotating shaft 31 that pivotally supports the link arm 24, and a pin 32 that is inserted and fixed in a hole (not shown) formed in the shaft 18 located on the suspension source side of the rotating shaft 31. It is arranged in a compressed state between the two, and when the shaft 18 is in the most advanced state, an urging force is applied so as to press the rotating shaft 31 that supports the link arm 24 against the door end side of the elongated hole 182 (FIG. 6).

The pair of interlocking arms 25 and the link arm 24 are pivotally supported by the rotating shaft 33, and the other end of the link arm 24 and the base portion 27 are pivotally supported by the rotating shaft 34. In FIG. 4, the shaft 18 is retracted so that the structure of each member can be easily grasped, and the rotating shaft 31 that pivotally supports the link arm 24 on the shaft 18 is located on the hanging side of the elongated hole 182. The rotating shaft 30 pivotally supported by the base portion 23 of the interlocking arm 25 is located on the hanging side of the elongated hole 181 (state of FIG. 8B).

Since the second link mechanism 22 has basically the same structure as the first link mechanism 21, the same members are designated by the same reference numerals, and detailed description thereof will be omitted. The pair of link arms 26, 26 arranged so as to sandwich the shaft 18 of the second link mechanism 22 in the width direction are the pair of link arms 24, 24 arranged so as to sandwich the shaft 18 of the first link mechanism 21 in the width direction. The dimension in the longitudinal direction is shorter than that of the above.

Further, the rotating shaft 31 for pivotally supporting the pair of link arms 26, 26 arranged so as to sandwich the shaft 18 of the second link mechanism 22 with the shaft 18 is a hole of a perfect circle formed in the shaft 18 (FIG. It is inserted through the hole (not shown) and cannot move in the axial direction in the hole. A push spring 41, which is an urging means, is arranged inside the shaft 18 between the rotating shaft 31 that pivotally supports the link arm 26 and the rotating shaft 30 that pivotally supports the interlocking arm 25. By this push spring 41, one end axially supported by the shaft 18 of the link arm 26 and one end axially supported by the base portion 23 of the interlocking arm 25 are always attached in a direction in which they are relatively separated from each other. Power is given.

As shown in FIG. 6, the upper end of the suspension spring 42 extending in the vertical direction is fixed to the vertical frame 74 on the door end side of the door body 7, and the lower end of the suspension spring 42 is the door end side of the lower closing member 12. It is fixed to the end, and due to the elastic return force of the suspension spring 42, an urging force that is always pulled upward is acting on the door end side of the lower closing member 12.

The suspension spring 42 exerts an urging force that balances the load of the lower closing member 12, and the urging force does not affect the closing operation of the lower advancing / retreating mechanism 20 described above.

Next, opening and closing of the door body 7 will be described with reference to FIG. In FIG. 5, for convenience of explanation, the gear hinge 5 is shown by a two-dot dashed line.

FIG. 5A shows a state in which the door body 7 is opened by about 40 degrees in the opened state, but the door body 7 can actually be opened by 180 degrees. As shown in FIG. 5B, the tip portion 18a of the shaft 18 is separated from the door support portion 2 in the open state in which the door body 7 and the gear hinge 5 connected to the door body 7 are opened by a predetermined value or more. Specifically, the receiving portion 43 arranged in the vertical frame 2a of the door supporting portion 2 and the tip end portion 18a of the shaft 18 are separated from each other. In this state, the shaft 18 is positioned at the position where it is advanced by the maximum amount due to the urging force of the suspension spring 42 (see FIG. 6) and the push spring 41 on the second link mechanism 22 side, and the lower closing member 12 is also at the uppermost position. It is held at the position of.

When the door body 7 is closed from the open state of FIG. 5A, the tip portion 18a of the shaft 18 comes into contact with the receiving portion 43 arranged in the vertical frame 2a of the door support portion 2, and the door body 7 The gear hinge 5 is closed by regressing as if pushed inward. The regressive operation of the shaft 18 is converted into an operation of lowering the lower closing member 12 by the first link mechanism 21 and the second link mechanism 22.

Next, the lowering operation of the lower closing member 12 by the lower advancing / retreating mechanism 20 in the closing operation of the door body 7 will be described with reference to FIGS. 7 and 8. In FIGS. 7 and 8, for convenience of explanation, when the door body 7 is closed, the door body 7 approaches the receiving portion 43 arranged in the vertical frame 2a of the door support portion 2 due to the narrowing of the opening degree. The aspect is schematically described, the door support portion 2 is shown by a broken line, and the door body 7 is always viewed from the front side regardless of the opening degree.

The lower advancing / retreating mechanism 20 is a so-called Scott Russell mechanism, and when the door body 7 is closed and the shaft 18 is retracted, one end (rotation) of the link arm 24 of the first link mechanism 21 pivotally supported by the shaft 18 is rotated. The shaft 31) moves integrally with the shaft 18 in the backward direction, is pivotally supported by the base portion 23 (see FIG. 4) of the interlocking arm 25, and one end (rotating shaft 30) of the interlocking arm 25 whose position does not change. ) And one end of the link arm 24 (rotational shaft 31) are brought close to each other. At this time, since the other end (rotating shaft 33) of the interlocking arm 25 is pivotally supported at the central portion in the longitudinal direction of the link arm 24, one end of the link arm 24 (rotating shaft 31) and one end of the interlocking arm 25 The other end (rotational shaft 33) of the interlocking arm 25 is moved downward by being brought close to the (rotating shaft 30). The downward movement of the other end (rotating shaft 33) of the interlocking arm 25 raises the link arm 24, and the lower closing member 12 pivotally supported by the other end (rotating shaft 34) of the link arm 24 is lowered. .. The second link mechanism 22 has the same structure as the first link mechanism 21, and operates in the same manner as the second link mechanism 22.

On the contrary, when the door body 7 is opened, the link mechanism 21 contracts when the shaft 18 is retracted. Specifically, one end (rotating shaft 30) of the interlocking arm 25 and the link arm 24 One end (rotating shaft 31) is separated, the link arm 24 lays down, and the lower closing member 12 pivotally supported by the other end (rotating shaft 34) of the link arm 24 is raised.

As shown in FIG. 6, the link arm 24 of the first link mechanism 21 located on the hanging side of the door body 7 is compared with the link arm 26 of the second link mechanism 22 located on the door end side of the door body 7. Therefore, the dimension in the longitudinal direction is formed to be long. The longitudinal dimension referred to here refers to the distance from the rotating shaft 31 of the link arms 24 and 26 and the shaft 18 to the rotating shaft 34 that pivotally supports the lower closing member 12 and the link arms 24 and 26. ..

As described above, in the first link mechanism 21 and the second link 22, the link arms 24 and 26 rise due to the downward movement of the other end (rotating shaft 33) of the interlocking arm 25, and the other of the link arms 24 and 26. Since the lower closing member 12 pivotally supported at the end (rotating shaft 34) is lowered, the lower closing member 12 and the link arm 24, 26 can be separated from the rotating shaft 31 of the link arms 24 and 26 and the shaft 18. The longer the distance to the rotating shaft 34 to be pivotally supported, the larger the downward movement stroke of the other ends (rotating shaft 33) of the link arms 24 and 26.

That is, the displacement of the lower closing member 12 by the lower advancing / retreating mechanism 20 linked to the horizontal displacement of the retreating motion of the shaft 18 is the suspension side of the lower closing member 12 having the link arm 24 having a long longitudinal dimension. The first link mechanism 21 of the above is larger than the second link mechanism 22 on the door end side having the link arm 26 having a relatively short longitudinal dimension.

Therefore, when the shaft 18 is retracted, the link arm 24 of the first link mechanism 21 and the link arm 26 of the second link mechanism 22 simultaneously start the operation of lowering the lower closing member 12, while simultaneously starting the operation of lowering the lower closing member 12. Since the displacement of the lowering motion of the link arm 24 of the first link mechanism 21 is large, the hanging side of the lower closing member 12 lowered by the first link mechanism 21 is larger than the door end side lowered by the second link mechanism 22. It descends, and as shown in FIG. 7A, it descends toward the floor surface in an inclined state in which the hanging side is lowered.

As shown in FIG. 7B, the lower closing member 12 is inclined toward the floor surface with the hanging side lowered by the first link mechanism 21 and the second link mechanism 22 interlocking with the regressive operation of the shaft 18. When lowered, the hanging side first comes into contact with the floor surface F. When the door body 7 is further closed and the shaft 18 is further retracted, the lower closing member 12 gradually approaches the floor surface F from the hanging side to the door end side as shown in FIG. 8A. I will do it.

When the shaft 18 further regresses after the hanging side of the lower closing member 12 comes into contact with the floor surface F, as shown in FIG. 8A, in the first link mechanism 21 on the hanging side, the lower closing member 12 Due to the reaction force from the floor surface F accompanying the descent of the link arm 24, the push spring 41 arranged in a compressed state between the rotating shaft 31 that pivotally supports the link arm 24 and the pin 32 contracts, and the link arm 24 is pivotally supported. The rotating shaft 31 moves to the hanging side of the elongated hole 181.

Then, when the door body 7 is in the closed state and the closing operation is completed, the entire surface of the lower closing member 12 in the left-right direction comes into contact with the floor surface F due to the lowering of the lower closing member 12 on the door end side by the second link mechanism 22. , The space between the lower end of the door body 7 and the floor surface F is completely closed (see FIG. 8B).

Further, in the second link mechanism 22, the shaft 18 regresses so that the rotating shaft 30 between the interlocking arm 25 and the base portion 23 and the rotating shaft 31 between the shaft 18 of the link arm 26 are brought close to each other. The push spring 41 is compressed by. Therefore, when the reaction force from the door support portion 2 decreases in the process from the closed state to the open state of the door body 7, the shaft 18 is pushed out to the door support portion 2 side by the urging force of the push spring 41, and the interlocking arm 25 The rotating shaft 30 of the base portion 23 and the rotating shaft 31 of the shaft 18 of the link arm 26 are separated from each other, which serves as a power to raise the lower closing member 12.

As described above, in the process of closing the door body 7, the lower advancing / retreating mechanism 20 exerts a pressing force on the floor surface F from the hanging side in the left-right direction of the lower closing member 12 toward the door end side. Since the door body 7 is operated, the door body 7 can be smoothly closed without suddenly generating a large frictional resistance in the process of changing the door body 7 from the open state to the closed state.

Further, the hanging side of the door body 7 is not easily affected by the frictional resistance of the lower closing member 12 because the distance from the gear hinge 5 which is the rotation support shaft of the door body 7 is short, that is, the arm length is short. Since the hanging side of the lower closing member 12 comes into contact with the floor surface F in advance of the door end side, the door body 7 can be smoothly closed.

Further, when the shaft 18 is retracted, the lower closing member 12 descends toward the floor surface in an inclined state in which the hanging side is lower than the door end side, so that the door body 7 is changed from the open state to the closed state. In the initial stage where the lower closing member comes into contact with the floor surface in the process, the door body 7 can be smoothly closed without being affected by the frictional resistance of the lower closing member 12.

Further, between the shaft 18 and the connection end portion of the link arm 24 of the first link mechanism 21 on the suspension side, a push spring 40 that constantly applies a urging force in a direction in which the shaft 18 is relatively separated from each other is interposed. There is. According to this, when the shaft 18 further regresses after the hanging side of the lower closing member 12 comes into contact with each other, the first link mechanism 21 has a rotating shaft that pivotally supports the link arm 24 by the reaction force from the floor surface F. The push spring 40 arranged between the pin 31 and the pin 32 is contracted, and the rotating shaft 31 that pivotally supports the link arm 24 moves to the hanging side of the elongated hole 181. Therefore, the door body 7 acts on the floor surface F from the link arm 24 on the hanging side of the lower closing member 12 that first came into contact with the floor surface F in the process of changing from the open state to the closed state via the lower closing member 12. The force is not excessive due to the contraction of the push spring 40, the door body 7 can be smoothly closed, and the first link mechanism 21 can be prevented from being damaged. In addition, by arranging the push spring 40 in the shaft 18, the structure can be made compact.

Further, when the door body 7 is opened, the operation mode of the lower advancing / retreating mechanism 20 is reversed. Specifically, in conjunction with the advance movement of the shaft 18, the lower advance / retreat mechanism 20 moves from the door end side in the left-right direction of the lower closing member 12 to the floor surface F in the process of opening the door body 7. On the other hand, the contacted portion gradually shrinks. Therefore, in the process of changing the door body 7 from the closed state to the open state, a large frictional resistance does not suddenly occur at a certain point, and the door body 7 can be smoothly opened.

Further, since the center of gravity of the movable partition panel 1 with a door body suspended by the hanging support members 9 and 9 is difficult to balance in the left-right direction, the door support portion 2 itself hangs down on the door tip side. However, since the lower closing member 12 in this embodiment descends with a delay on the door end side, it is difficult for the door end side of the door body 7 to come into contact with the floor surface F during the closing operation of the door body 7. The closing operation can be performed smoothly.

Although examples of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these examples, and any changes or additions within the scope of the gist of the present invention are included in the present invention. Is done.

For example, in the present embodiment, the lower advancing / retreating mechanism 20 has been described with a configuration using the first link mechanism 21 and the second link mechanism 22 having link arms 24 and 26 having different lengths, but the present invention is not limited to this, and for example, FIG. As in the modified example 1 shown in the above, two cam structures 121 and 122 having inclined surfaces having different inclination angles may be used. Specifically, the cam structure 121 having a steeply inclined surface is fixed to the hanging source side of the shaft 18, the cam structure 122 having a gently inclined surface is fixed to the door end side, and the hanging source is fixed to the lower closing member 12. Rollers 131 and 132 are rotatably fixed to the side and the door end side, respectively. According to this, the displacement of the lower closing member 12 by the lower advancing / retreating mechanism linked to the horizontal displacement of the retreating motion of the shaft 18 is fixed to the suspension source side riding on the cam structure 121 having a steeply inclined surface. The roller 131 side is larger than the roller 132 side fixed to the suspension source side that rides on the cam structure 122 having a relatively gentle inclined surface.

Further, in the present embodiment, the lower advancing / retreating mechanism 20 has been described with the configuration in which the first link mechanism 21 and the second link mechanism 22 are used on the hanging side and the door end side, respectively, but the present invention is not limited to this, and is shown in FIG. It may be configured by using one link mechanism as in the modified example 2. Specifically, the shaft 18 is pivotally supported by a rotating body 123 on a rotating shaft 135. The rotating body 123 is arranged closer to the suspension source, has two corner portions 123a and 123b in the rotation direction, and is rotatably supported on the lower frame 75 by the rotating shaft 136 below the rotating shaft 135. According to this, the first corner portion 123a of the rotating body 123 first abuts on the lower closing member 12, pushes down the hanging side, and the second corner portion 123b is delayed and hits the lower closing member 12. By touching and pushing down the door end side, in the process of closing the door body 7, the lower closing member 12 gradually approaches the floor surface F from the hanging side in the left-right direction toward the door end side. It becomes.

Further, in the present embodiment, the lower advancing / retreating mechanism 20 gradually approaches the floor surface F from the hanging side in the left-right direction of the lower closing member 12 toward the door end side in the process of closing the door body 7. However, the configuration is not limited to this, and the lower closing member 12 may be configured to gradually approach the floor surface F from the door end side in the left-right direction toward the hanging source side.

Further, the lower closing member 12 is suspended and supported by an urging means or the like, and the first link mechanism 21 of the lower advancing / retreating mechanism 20, the link arms 24, 26 of the second link mechanism 22, and the lower closing member 12 are moved in the vertical direction. By separating the link arms 24 and 26 from each other, the link arms 24 and 26 are configured so that the lower closing member 12 is not immediately lowered until just before the closed state, and the link arms 24 and 26 and the lower closing member 12 are separated immediately before the closed state. The lower closing member 12 may be lowered by abutting against each other.
