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 (for example, 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.

The shaft of Patent Document 1 is constantly urged toward the hanging side by a horizontal coil spring attached to the shaft, and the horizontal coil spring separates the door support portion from the door body during the opening operation. At that time, the shaft is configured to advance to the hanging side. In addition, the urging force of this horizontal coil spring also has a function of contracting the link mechanism during the opening operation. However, in Patent Document 1, since the lower closing member is suspended by the link mechanism, the horizontal coil is used. When the spring is opened, it requires an urging force to lift the lower closing member in addition to the contraction of the link, and when the spring is closed, a large force is required to contract the horizontal coil spring, which makes it impossible to perform a smooth closing operation. There was a problem.

Therefore, in some partition panels not provided with a door, a lower closing member and a lower moving / retreating mechanism for advancing / retreating the lower closing member are housed in the lower part of the panel body (see, for example, Patent Document 2). In Patent Document 2, a coil spring that supplementarily suspends the weight of the lower closing member is attached between the lower closing member and the door body. This coil spring exerts an urging force that balances with the load, and the urging force does not affect the lowering operation of the lower closing member by the lower advancing / retreating mechanism.

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

By applying the structure of the lower advancing / retreating mechanism and the coil spring as shown in Patent Document 2 to the partition panel with the door body, the horizontal coil spring that exerts an urging force in the direction of advancing the shaft when the door body is closed. A large force is not required for contraction, and a smooth closing operation can be performed. By the way, in recent years, a translucent panel member may be used for the door body in order to produce a feeling of openness of the space. In such a door body, the translucent panel member is an upper frame, two vertical frames and the like. It is held by a four-sided frame-shaped frame member composed of a lower frame, and the above-mentioned shaft, horizontal coil spring, pressing portion, lower closing member, two link mechanisms and coil spring are arranged in the lower frame. .. However, when a coil spring as shown in Patent Document 2 is used, a space for accommodating the coil spring is required in the lower frame, so that the vertical dimension of the lower frame becomes large, which causes transparency in the door body. The ratio of the occupied area below the optical panel member is limited, and there is a risk that a feeling of spatial openness cannot be sufficiently produced.

The present invention has been made by paying attention to such a problem, and is provided with a lower closing member that moves up and down with respect to the floor surface in conjunction with an opening / closing operation of the door body, and a door body using a translucent panel member. It is an object of the present invention to provide a partition panel with a door body which can sufficiently produce a feeling of spatial openness of the door body by reducing the vertical dimension of the lower frame.

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
A door body in which a translucent panel member is held by a frame member composed of an upper frame, two vertical frames and a lower frame is rotatably attached to a door support portion suspended via the suspension member. The lower frame is provided with a lower closing member and a moving portion that is moved forward and backward by opening and closing the door body, and a lower moving / retreating mechanism that converts the moving forward / backward movement of the moving portion into an operation of raising / lowering the lower closing member. , Is a partition panel with a door body that houses
The vertical frame of the door body is characterized in that an urging member for urging the lower closing member upward is arranged.
According to this feature, the urging member that urges the lower closing member upward eliminates the need for a large force for the raising operation of the lower closing member by the lower advancing / retreating mechanism, and the door body can be smoothly opened and urged. By arranging the members in the vertical frame of the door body, the space in the lower frame can be made the minimum size necessary for accommodating the lower closing member and the lower advancing / retreating mechanism, and the vertical dimension of the lower frame can be reduced. Therefore, the ratio of the occupied area of the translucent panel member in the door body is increased, and a feeling of spatial openness can be sufficiently produced.

The vertical frame is characterized in that concave grooves forming openings on the left and right outer sides are formed, and the urging member is housed in the concave grooves.
According to this feature, the urging member is located inside in the left-right direction from the end of the vertical frame that is abutted with the partition panel that is connected in the left-right direction. It is possible to prevent the urging member from being damaged.

The opening of the concave groove formed in the vertical frame is characterized in that it is vertically closed by a cushioning member.
According to this feature, since the progress is buffered in the concave groove such as the convex portion of the partition panel connected in the left-right direction by the cushioning member, the urging member housed in the concave groove can be protected.

The side end of the lower closing member is characterized in that it protrudes to the left and right outward from the inner surface of the concave groove.
According to this feature, the urging member can be extended linearly in the vertical direction, smoothly expanded and contracted, and does not hinder the raising and lowering of the lower closing member.

The urging member is characterized in that it is provided in the vertical frame on the door end side.
According to this feature, the urging member is easily accessible during maintenance.

The urging member is characterized by being a tension spring that suspends the lower closing member.

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.

The guide member 19 is fixed to the bottom surface of the lower frame 75 of the door body 7 with screws or the like. 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 of the door body 7, a link arm 24 having one end pivotally supported by the shaft 18, and one end to the base portion 23. An interlocking arm 25 that is axially supported and the other end of which is pivotally supported at the central portion in the longitudinal direction of the link arm 24, and a base portion 27 that is fixed to the lower closing member 12 and the other end of the link arm 24 is pivotally supported. , Is configured.

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 pivotally supports the link arm 24 against the door end side of the elongated hole 182. 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.

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.

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. 5A, 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 coil spring 42 (see FIG. 4) as the urging member and the push spring 41 on the second link mechanism 22 side, and the lower part is closed. The member 12 is also held at the uppermost position.

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.

As shown in FIG. 4, the upper end of the coil 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 coil 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 coil spring 42, an urging force that is always pulled upward is acting on the door end side of the lower closing member 12. In this embodiment, the coil spring 42 is a tension spring.

Specifically, as shown in FIG. 6, the vertical frame 74 on the door end side of the door body 7 includes a core member 80 extending in the vertical direction of the door body 7, a covering member 81 extending in the vertical direction on the front and rear surfaces, and a cover. It is composed of a member 82 and. The core member 80 is a steel plate having a thickness in the left-right direction, and the covering member 81 and the cover member 82 are extruded products made of metal such as an aluminum alloy. The core member 80 and the covering member 81 are fixed by screws 83, and the covering member 81 and the cover member 82 are fixed by uneven engagement and screws.

The core member 80 and the covering member 81 are fixed to form an integral plate having a thickness in the left-right direction, and are arranged between the translucent panels 71 and 71. The translucent panels 71 and 71 are adhesively fixed to the covering member 81 by an adhesive layer (not shown) such as double-sided tape.

The cover member 82 extends to the left and right side end faces of the translucent panels 71 and 71 so as to protect the translucent panels 71 and 71. Further, the cover member 82 is provided with a recessed groove 85 that is recessed toward the inside of the door body 7.

As shown in FIGS. 6 and 7 (a) and 7 (b), the coil spring 42 is arranged in the concave groove 85 of the cover member 82 so that the longitudinal direction and the expansion / contraction direction face up and down. Further, a cushioning member 84 is engaged with the opening of the concave groove 85 in an uneven manner in the vertical direction, and the opening is closed.

As shown in FIGS. 7A and 7B, in the coil spring 42, the lower end portion 42a is fixed to the lower closing member 12, and the upper end portion 42b is formed in the concave groove 85 of the cover member 82 via the fixing member 86. It is fixed to the back surface 85a. Specifically, the lower closing member 12 is arranged so as to project so that the side end on the door end side extends to a position in the concave groove 85 of the cover member 82, and the fixing pin 87 is arranged at the end on the door end side. Is fixed, and the lower end portion 42a of the coil spring 42 is fixed to the fixing pin 87.

As shown in FIGS. 7A and 7B, the fixing member 86 is formed with an elongated hole 86a extending in the vertical direction, and the lower end portion of the fixing member 86 is bent outward, so that the fixing member 86 is bent. Three mounting holes 86c that can lock and fix the upper end portion 42b of the coil spring 42 in the front-rear direction (horizontal direction) are formed in the lower end portion 86b. A body portion having a diameter smaller than the head of the fixing screw 88 fixed to the inner surface 85a of the concave groove 85 can be inserted into the elongated hole 86a, and the fixing screw 88 has an arbitrary height within the range of the elongated hole 86a. It can be fixed to the head, and the fixing position of the fixing member 86 with the concave groove 85 can be adjusted in the vertical direction. Thereby, the spring length of the coil spring 42 can be changed and the spring constant can be adjusted.

Further, since the lower end portion 42a of the coil spring 42 is locked and fixed to the fixing pin 87, the lower end portion 42a is placed at an arbitrary position in the longitudinal direction of the fixing pin 87, that is, at an arbitrary position in the thickness direction of the door body 7. The fixing position can be adjusted, and by selecting the fixing position of the upper end portion 42b from the three mounting holes 86c, the fixing position of the upper end portion 42b in the thickness direction of the door body 7 can be adjusted.

Even when the fixing member 86 is fixed to the lowermost position, the coil spring 42 has a vertical dimension such that the upper end portion 42b of the coil spring 42 is located above the upper end of the lower frame 75 of the door body 7. It is fixed to.

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. 8 and 9. In FIGS. 8 and 9, 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 shaft 18 is retracted when the door body 7 is opened, the link mechanism 21 contracts, 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. 4, 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 mechanism 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 link arms 24 and 26 Since the lower closing member 12 pivotally supported at the other end (rotating shaft 34) is lowered, the lower closing member 12 and the link arm 24, 26 are formed 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 that supports the shaft, 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. 8A, it descends toward the floor surface in an inclined state in which the hanging side is lowered.

As shown in FIG. 8B, 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, as shown in FIG. 9A, the lower closing member 12 gradually approaches the floor surface F from the hanging side toward the door end side. I will do it.

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. 9B).

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, the coil spring 42 that auxiliaryly suspends the weight of the lower closing member 12 does not require a large force for the lower closing member 12 to move up by the lower advancing / retreating mechanism 20, and the door body 7 is smoothly opened. be able to. Then, by arranging the coil spring 42 in the vertical frame 74 of the door body 7, the space in the lower frame 75 is the minimum size necessary for accommodating the lower closing member 12 and the lower advancing / retreating mechanism 20. The vertical dimension of the lower frame 75 can be reduced. Therefore, the ratio of the occupied area of the translucent panel 71 in the door body 7 is increased, and a feeling of spatial openness can be sufficiently produced.

Further, the coil spring 42 is housed in a concave groove 85 formed in the vertical frame 74 and forming an opening outward, and is left and right from the end of the vertical frame 74 that is abutted with the partition panel 101 connected in the left-right direction. It will be located inside the direction. Therefore, it is possible to prevent the coil spring 42 from being damaged when the mobile partition panel 1 with a door body and the partition panel 101 are connected to each other. Further, since the coil spring 42 is not visible from the front side, it is excellent in aesthetic appearance.

Further, the opening of the concave groove 85 formed in the vertical frame 74 is closed vertically by the cushioning member 84, and the convex portion of the partition panel 101 connected in the left-right direction by the cushioning member 84 or the open state. Since the progress is buffered in the concave groove 85 of the object colliding with the side surface of the exposed door body 7, the coil spring 42 housed in the concave groove 85 can be effectively protected.

Further, since the side end of the lower closing member 12 protrudes to the left and right outward from the inner surface 85a of the concave groove 85, the coil spring 42 arranged in the concave groove 85 can be extended linearly in the vertical direction. , It expands and contracts smoothly, and it is difficult to prevent the lower closing member 12 from moving up and down.

Further, since the coil spring 42 is provided on the vertical frame 74 on the door end side, it is easy to access from the door end side of the door body 7 in the open state during maintenance.

Further, since the coil spring 42 is a tension spring that suspends the lower closing member 12, the lower end of the coil spring 42 may be arranged so as to be locked with the lower closing member 12 and the upper end with the vertical frame 74. The structure of the closing member 12 and the vertical frame 12 can be simplified.

Further, the coil spring 42 has a configuration in which the spring length in the state where the lower closing member 12 is located at the uppermost position is longer than the descending stroke of the lower closing member 12. In other words, the coil spring 42 is required to extend the coil spring 42 in the lowering operation of the lower closing member 12 by the lower advancing / retreating mechanism 20 because the ratio of the lowering stroke of the lower closing member 12 to the spring length is small. The force is small, and it is unlikely to be a resistance to the closing operation of the door body 7, which is the power for the lowering operation by the lower advancing / retreating mechanism 20, and the closing operation can be performed smoothly.

Further, in the above 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. By arranging the coil spring 42 on the door end side, it is possible to effectively prevent the door end side of the lower closing member 12 from hanging down to the floor surface F side, and the door body 7 is closed from the open state. In the process of becoming a state, a large frictional resistance does not suddenly occur at a certain point, and the door body 7 can be smoothly closed.

Further, as shown in FIG. 4, the link arms 24, 26 and the interlocking arm 25 of the first link mechanism 21 and the second link mechanism 22 are pivotally supported by the lower closing member 12 of the link arms 24, 26. The end and one end pivotally supported by the base portion 23 of the interlocking arm 25 are arranged so as to face the door end side and open so as to form an inverted Y shape in front view. Here, since the coil spring 42 is arranged on the door end side, it is pivotally supported by the other end of the link arms 24 and 26, which is pivotally supported by the lower closing member 12, and the base portion 23 of the interlocking arm 25. It is possible to effectively suppress the opening of one end, and it is possible to effectively suppress the door end side of the lower closing member 12 from hanging down to the floor surface F side when the door body 7 is in the open state. it can.

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 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 coil spring 42 is not limited to the coil spring as in the above embodiment, and for example, the other end of a linear member having a leaf spring for generating an urging force at one end is fixed to the lower closing member 12, and the door body 7 is used. A pulley for holding the linear member may be interposed in the vertical frame 74 of the above.

Further, the vertical frame 74 of the door body 7 may be formed in a hollow shape instead of providing the concave groove 85, and the coil spring 42 may be arranged in the hollow space.

Further, the coil spring 42 may be arranged in the vertical frame 74 of the door body 7 on the hanging side.

Further, the side end of the lower closing member 12 does not have to protrude into the concave groove 85 of the vertical frame 74 of the door body 7.

Further, in the present embodiment, the lower advancing / retreating mechanism 20 has been described with the configuration using the first link mechanism 21 and the second link mechanism 22 having the link arms 24 and 26 having different lengths, but the present invention is not limited to this.
In the process of closing / opening the door body 7, the lower advancing / retreating mechanism performs an operation of gradually approaching / separating the lower closing member 12 from one side in the left-right direction toward the other side with respect to the floor surface. For example, the coil spring 42 of the present invention may have any configuration, and the coil spring 42 of the present invention has a floor surface from one side to the other side in the left-right direction of the lower closing member 12 like the lower advancing / retreating mechanism 20 of the present embodiment. The application is not limited to those that gradually approach and separate from each other, and may be applied to a moving partition panel with a door body having a lower advancing / retreating mechanism having a structure in which the lower closing member 12 is moved up and down horizontally.

Further, as the urging member for urging the lower closing member 12 upward, the coil spring 42 which is a tension spring has been described as an example, but the urging member may be a compression spring, and in this case, the vertical frame or the like. The shape of the lower closing member may be changed so that the lower end of the compression spring is in contact with the vertical frame and the upper end is in contact with the lower closing member.
