Description

  The present invention relates to a configuration of an electric partition device.

  Patent document 1 discloses this kind of partition device (sliding wall). In FIG. 1 of Patent Document 1, a plurality of partition wall elements are provided along the guide rails, and each element is provided with a driving device. The element adjacent to the storage magazine is pivotally supported in the region of one end of the guide rail, and the drive device arranged corresponding to the element is guided along the storage rail branched from the guide rail. . The drive device and the element are connected by a connecting member. According to this configuration, the sliding wall elements can be moved and stored while being stacked in the storage magazine.

In addition, as shown in FIG. 1, the partition wall of Patent Document 2 supports the center of each of the plurality of panels with a shaft that can rotate and move along the guide rail. It is connected with a hinge to form a foldable partition wall. And a connecting arm is attached to each axis so that rotation is possible, and both ends of the connection arm are connected so that rotation is possible, respectively, and a pantograph is constituted by a connection arm and a panel. The connecting arm is connected to a belt driven by an electric motor in an opening direction and a closing direction via a driving arm. With this configuration, the panel can be extended and folded.
Japanese translation of PCT publication No. 2003-513184 (Claim 1, paragraph number 0014, FIG. 1) JP-A-4-38388 ((2) page 5, upper right column, line 5 to lower left column, line 7, FIG. 1)

  However, the configuration of Patent Document 1 requires a driving device for each element of the partition wall, and it becomes necessary to individually control driving / stopping of the driving device, resulting in a complicated and expensive configuration. On the other hand, although Patent Document 2 has a configuration with only one motor, the above-mentioned problem does not occur. However, since all the panels are moved and extended / folded simultaneously by driving the motor, A large driving force is required.

  In any of the configurations of Patent Documents 1 and 2, the element or panel in the retracted and folded (folded) state is perpendicular to or close to the element or panel in the advanced or extended state. Yes. Therefore, the place where the stacked (folded) elements or panels are stored protrudes in a direction perpendicular to the guide rails, which easily obstructs a passing person.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  ◆ According to an aspect of the present invention, an electric partition device configured as follows is provided. A plurality of partitions, and a guide rail that guides these partitions so as to be movable between an advanced position and a retracted position. Each partition is movable while maintaining its orientation between the advance position and the retracted position. The guide rail has a straight portion and is configured to have an inclined portion at a portion corresponding to the retracted position of the partition. It is provided with a connecting member for connecting adjacent partitions so that the adjacent directions can be changed. When the two partitions are displaced in the thickness direction, one of them slides along the plane of the partition with respect to the other. Both partitions are connected as possible. Further, the plurality of partitions are configured to move in conjunction with each other by driving the most door-side partition with an electric motor. In the advanced position, the plurality of partitions are linearly continuous. In the retracted position, the plurality of partitions are stacked in the thickness direction.

  In this configuration, the partition is stacked in the thickness direction while maintaining the same orientation as the advanced position at the retracted position. Therefore, it is less likely that the partitions that are overlapped at the retracted position protrude into the space and obstruct the passerby. Furthermore, since the partition moves while keeping its direction constant, the movement trajectory of the partition between the retracted position and the advanced position can be made compact. In addition, the partition that travels to the retracted position is moved so as to be shifted in the thickness direction along the inclined portion of the guide rail, so that the subsequent partitions can be sequentially moved to the inclined portion (retracted position). As a result, a simple configuration in which the partitions are stacked in the thickness direction at the retracted position can be realized. In addition, since the driving force of the electric motor that drives the partition closest to the door end is moved in conjunction with the other partition, the drive configuration eliminates the need to provide an electric motor for each partition. Is simplified and its control is also simplified. Furthermore, the adjacent partitions can be connected by a connecting member while switching the adjacent directions, such as adjoining in a straight line at the advanced position and adjacent to each other in the thickness direction at the retracted position. Further, when the partition is displaced in the thickness direction, one partition can slide along the plane of the partition with respect to the other, so that the partition can be overlapped in the thickness direction, or the overlapped state can be eliminated. Therefore, it is possible to smoothly switch between the advance position and the retreat position of the plurality of partitions.

  The above-described electric partition device is preferably configured as follows. The guide rail includes two rails parallel to each other. Each of the plurality of partitions has door wheels on the door end side and the door end side, the door wheel on the door end side on the rail on one side, the door wheel on the door end side on the rail on the other side, respectively It is supported.

  Thereby, each partition can be supported stably. In addition, by appropriately setting the shape of the rail, it is possible to provide a simple configuration in which each partition is moved so as to be displaced in the thickness direction while maintaining its orientation.

  In the electric partition device, the two rails are preferably arranged with different heights.

  Thereby, while being able to avoid interference between rails, it can be made into the rational layout which can also prevent interference between the doorwheels on the door end side and the door bottom side.

  The above-described electric partition device is preferably configured as follows. The most door-side partition is configured to move between the advance position and the retracted position without sliding in the thickness direction. Further, the most door-side partition is fixed to a driving belt driven by the electric motor.

  In this configuration, the partition closest to the door end only moves linearly without sliding in the thickness direction (that is, along the plane of the partition). Therefore, the configuration for simultaneously driving a plurality of partitions can be made simple and inexpensive using a drive belt.

  In the electric partition device, the connecting member is preferably an arm member whose one end is rotatably supported by one partition and the other end is slidably connected to the other partition.

  Thereby, the adjacent direction of the partition can be switched by rotating the arm member as the connecting member, and one of the partitions is along the plane of the partition with respect to the other by sliding the other end of the connecting member. Can slide. Therefore, a simple and rational configuration can be obtained.

  In the electric partition device, one end of the arm member is rotatably supported on the upper part of the partition, and the other end of the arm member is slidable along a slide groove formed on the upper part of the partition. It is preferable to be configured.

  Thereby, since a connection structure will be arrange | positioned at the upper part of a partition, a connection structure can be made hard to be conspicuous, and it is excellent in the designability.

  ◆ The electric partition device includes a rotation restricting means for restricting a rotation range of the arm member, and the rotation restricting means is provided when the arm member is substantially oriented in the thickness direction of the partition. The arm member is preferably provided so as to prevent further rotation of the arm member.

  Thereby, the play and blurring of the partition can be reduced by the rotation restricting means. In particular, smooth sliding of the partition is realized by restricting the rotation of the arm member when the adjacent partitions slide along the plane of the partition. Further, when the partitions are stacked in the thickness direction, one partition can accurately transmit the force in the thickness direction to the other via the arm member.

  Next, embodiments of the invention will be described. 1 is a front view showing an overall configuration of an electric partition device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a line BB in FIG. It is a cross-sectional arrow view.

  The electric partition device 1 shown in FIGS. 1 to 3 includes a seamless frame 2 installed on a ceiling of a room, two guide rails 21 and 22 laid inside the seamless frame 2, and the guide rails. It has four flat panel bodies 11 to 14 suspended from and supported by 21 and 22. The panel bodies 11 to 14 as partitions are made of, for example, transparent tempered glass, and the top of each panel body 11 to 14 is a door-end side for supporting the panel body with respect to the guide rails 21 and 22. A hanger 31 and a hanger 32 on the door bottom side are provided.

  On one end side (door bottom side) of the guide rails 21 and 22, a door pocket 3 is installed below the seamless frame 2, and the door pocket 3 is formed with a vertically extending opening 26. . With this configuration, the panel bodies 11 to 14 are moved from the extended state (the state shown in FIG. 1), traveled to the inside of the door pocket 3 through the opening 26, and stored inside the door pocket 3 in a state of being stacked in the thickness direction. (See FIG. 10). In the following description, when the four panel bodies 11 to 14 are specified, the four panel bodies 11 to 14 may be referred to as “the first panel body” when counted from the side far from the door pocket 3.

  As shown in FIG. 1, the two guide rails 21 and 22 are arranged side by side inside the seamless frame 2. Both of the guide rails 21 and 22 extend horizontally in a straight line in a direction parallel to the plane of the panel bodies 11 to 14 (linear portions) in most regions. However, the guide rails 21 and 22 have inclined portions 21c and 22c that are slightly inclined by drawing an arc in a horizontal plane in the upper portion of the door pocket 3 (see FIG. 2).

  The inclined portions 21c and 22c of the two guide rails 21 and 22 are inclined in the same direction while being kept parallel, but the lower first guide rail 21 and the upper second guide rail 22 start the inclination. The position is different. Specifically, in FIG. 2, the first guide rail 21 starts to be inclined at a position corresponding to a position slightly inside the door pocket 3 from the opening 26 of the door pocket 3 (inclined portion 21 c). On the other hand, even if the second guide rail 22 enters the inside of the door pocket 3 from the position corresponding to the opening 26, the second guide rail 22 extends linearly by the length of about one sheet of the panel body. Inclination is started from the corresponding position (inclined portion 22c).

  As shown in FIG. 1, the door-side hanger 31 of each panel body 11 to 14 is supported by the lower first guide rail 21. On the other hand, the hanger 32 on the door bottom side of each panel body 11 to 14 is supported by the upper second guide rail 22.

  In the upper part of the door pocket 3, a drive unit 4 for driving the panel bodies 11 to 14 is installed inside the blind frame 2. The drive unit 4 is configured by integrating an electric motor and a gear box that decelerates its output. An output pulley 5 is fixed to the output shaft of the drive unit 4.

  A deceleration pulley 6 is rotatably supported at a position near the output pulley 5. The speed reduction pulley 6 is a two-stage pulley, and an endless speed reduction belt 7 is wound around the large diameter portion and the output pulley 5. A driven pulley 8 is rotatably supported at a position away from the speed reduction pulley 6 in the seamless frame 2, and an endless drive belt 9 is provided between the driven pulley 8 and the small diameter portion of the speed reduction pulley 6. It is wound. The first panel body 11 closest to the door end among the four panels is fixed to the drive belt 9 via a belt fixing member 25.

  With the above configuration, when the drive unit 4 is driven by supplying electric power through a power supply line (not shown), the rotational output is driven in a form in which deceleration and torque are increased via the output pulley 5, the reduction pulley 6, and the reduction belt 7. The belt 9 is driven. As a result, the first panel body 11 connected to the drive belt 9 through the belt fixing member 25 can be caused to travel along the guide rails 21 and 22 toward the door 3 and away from the door.

  Next, the structure of the hangers 31 and 32 provided to suspend the panel bodies 11 to 14 will be described mainly with reference to FIG. FIG. 4 is an enlarged view of a main part of FIG. 3 showing details in the frameless frame 2, and shows a hanger 32 provided on the door bottom side of the first panel body 11. In FIG. 4, the hanger 32 includes a base member 35 fixed to the upper end of the first panel body 11, a rotating shaft 36 installed on the top of the base member 35 with the axis line directed in the vertical direction, The suspension arm 37 is attached to the base member 35 so as to be rotatable around the rotation shaft 36, and the three rollers 61 to 63 are provided on the upper portion of the suspension arm 37.

  Of the three rollers, the first roller 61 and the second roller 62 are rotatably supported by the suspension arm 37 with their axes directed in the thickness direction of the first panel body 11, and the first roller 61 is the second roller 61. The upper surface of the guide rail 22 is configured such that the second roller 62 can roll on the lower surface. In the present embodiment, the first roller 61 corresponds to a door cart. Further, a roller arm 38 is fixed to the suspension arm 37, and a third roller 63 is supported at the tip of the suspension arm 37 so that the rotation axis thereof can be rotated in the vertical direction. The third roller 63 is configured to roll on the side surface of the second guide rail 22.

  In addition, about the hanger 31 by the side of the door of the 1st panel body 11, the vertical direction length of the suspension arm 37 is short, and the position where the three rollers 61-63 are lower than the hanger 32 by the door bottom side. In addition to being configured to be able to roll with respect to the first guide rail 21 (the chain line in FIG. 4), it is configured in exactly the same way as the configuration of the hanger 32 on the door bottom side described above. . Moreover, since the structure of the hanger 31 * 32 of the 2nd-4th panel bodies 12-14 is completely the same as the hanger 31 * 32 of the 1st panel body 11, description is abbreviate | omitted.

  With the above configuration, the four panel bodies 11 to 14 have the three rollers 61 to 63 of each hanger 31 (32) roll along the first guide rail 21 (second guide rail 22). The traveling direction can be moved while being guided by the guide rails 21 and 22. Even if the panel bodies 12 to 14 enter the door pocket 3 and the hangers 31 and 32 reach the inclined portions 21 c and 22 c of the guide rails 21 and 22, the suspension arm 37 is centered on the rotation shaft 36. By rotating, the direction of the rollers 61 to 63 is changed, and the panel bodies 12 to 14 can be moved in an oblique direction (that is, shifted in the thickness direction of the panel body) along the inclined portions 21c and 22c. It has become.

  As shown in FIG. 1, a stopper 27 is installed in the seamless frame 2 above the door pocket 3. The stopper 27 can be brought into contact with a belt fixing member 25 fixed to the first panel body 11 (see FIG. 10), and restricts the movement range of the first panel body 11. As a result, unlike the other panel bodies 12 to 14, the first panel body 11 does not move obliquely by the inclined portions 21 c and 22 c of the guide rail, but simply moves linearly along the linear portions of the guide rails 21 and 22. Only to do.

  As shown in FIG. 1, an appropriate groove is provided in the floor of the room, and a floor rail 41 is laid in the groove. The floor rail 41 has a shape substantially corresponding to the first guide rail 21 (including the inclined portion 21c) described above in plan view. In the door pocket 3, a branch rail 42 that is shallower than the floor rail 41 is branched from the floor rail 41. The branch rail 42 has a shape substantially corresponding to the second guide rail 22 (including the inclined portion 22 c) in the upper region of the door pocket 3.

  As shown in FIG. 1, at the lower part of each panel body 11-14, rollers 51 and 52 are provided on the door end side and the door bottom side, and the rollers 51 and 52 roll in the floor rail 41. It is possible. In the second to fourth panel bodies 12 to 14, the door-end side roller 51 is provided at a position lower than the door-end side roller 52, and the door-end side roller 51 is provided only in the deep floor rail 41. Rollable. On the other hand, the roller 52 on the door bottom side rolls in the shallow branch rail 42 at the portion of the door pocket 3. The floor rail 41 and the branch rail 42 are configured to guide the traveling directions of the panel bodies 11 to 14 together with the two guide rails 21 and 22 described above.

  Next, a configuration for connecting the panel bodies 11 to 14 will be described. FIG. 5 is an enlarged view of a main part of the front panel showing adjacent ends of the first panel body 11 and the second panel body 12. 6 is a cross-sectional view taken along line CC in FIG. 5, and FIG. 7 is a cross-sectional view taken along line DD in FIG.

  As shown well in FIGS. 5 and 7, one end of a connecting arm 45 a serving as a connecting member or an arm member is pivoted on the upper portion of the first panel body 11 at the end adjacent to the second panel body 12. It is supported freely. On the other hand, a slide groove 46 is provided on the upper surface of the second panel body 12 in a direction along the plane of the second panel body 12, and a roller 47 provided on the free end side of the connecting arm 45a is provided with the slide groove 46. Has been inserted inside. Further, as shown in FIG. 7, one end of the connecting arm 45b is similarly rotatably supported at an end of the second panel body 12 adjacent to the first panel body 11, and a roller provided on the free end side thereof. 47 rolls along a slide groove 46 provided in the first panel body 11.

  As shown in FIG. 7, a regulating body 48 protrudes downward from the middle part of each of the connecting arms 45a and 45b (see also FIG. 5). The first panel body 11 and the second panel body 12 are provided with rotation restricting members 49a and 49b so as to be able to contact the restricting body 48. The restricting body 48 and the turning restricting members 49a and 49b constitute a turning restricting means, whereby the connecting arms 45a and 45b are substantially along the plane of the panel body and along the thickness direction of the panel body. It is limited to an angle range of approximately 90 ° between the directions.

  As shown in FIGS. 5 and 6, a contact member 55 is fixed to the base member 35 of the hanger 32 on the door bottom side of the first panel body 11. On the other hand, the contact member 55 is also fixed to the base member 35 of the hanger 31 on the door end side of the second panel body 12. Both contact members 55 and 55 are provided so as to face each other and can contact each other.

  5 to 7 show the connection structure between the first panel body 11 and the second panel body 12, but the same connection structure is used for the second panel body 12, the third panel body 13, and the like. And between the third panel body 13 and the fourth panel body 14. With the above configuration, the contact member 55 and the connecting arms 45a and 45b distribute the driving force transmitted from the driving unit 4 to the first panel body 11 to the other panel bodies 12 to 14 to thereby provide four panel bodies 11. Serves as a distribution means for driving -14 simultaneously. In other words, it serves as a transmission means for transmitting the driving force for driving the first panel body 11 to the other panel bodies 12 to 14.

  Next, the operation of the electric partition device 1 having the above configuration will be described. FIG. 8 is a plan view showing a state in which the fourth panel body moves in a direction shifted in the thickness direction with respect to the third panel body, and FIG. 9 shows a state in which the fourth panel body is completely shifted in the thickness direction with respect to the third panel body. FIG. 10 is a front view showing a state in which the panel body is stored in the door pocket from the state of FIG. 1, and FIG. 11 is a cross-sectional view taken along the line EE of FIG.

  In the state shown in FIGS. 1 and 2, the four panel bodies 11 to 14 are aligned with each other in a state of coming out of the door pocket 3 and divide the room into two spaces. The positions of the four panel bodies 11 to 14 shown in FIGS. 1 and 2 may be referred to as “advance positions” hereinafter.

  From the state shown in FIGS. 1 and 2, the drive unit 4 of FIG. 1 is driven, and the first panel body 11 is driven in a direction approaching the door pocket 3 via the drive belt 9. Then, the contact member 55 of the first panel body 11 pushes the contact member 55 of the second panel body 12, and the contact member 55 of the second panel body 12 pushes the contact member 55 of the third panel body 13. The contact member 55 of the third panel body 13 pushes the contact member 55 of the fourth panel body 14. In this way, the driving force of the drive unit 4 is distributed and transmitted to each of the four panel bodies 11 to 14, and the panel bodies 11 to 14 travel simultaneously toward the door pocket 3 side in a straight line. To do. First, the fourth panel body 14 enters the door pocket 3 through the opening 26.

  When all of the fourth panel body 14 enters the interior of the door pocket 3, the hangers 31 and 32 of the fourth panel body 14 reach the inclined portions 21 c and 22 c of the guide rail and are pushed by the third panel body 13. With the orientation maintained, the fourth panel body 14 moves in an oblique direction, that is, in a thickness direction, inside the door pocket 3 as shown in FIGS. 8 to 9. At this time, the connecting arms 45a and 45b that connect the third panel body 13 and the fourth panel body 14 rotate accordingly.

  In addition, as shown in FIG. 6, the contact members 55 and 55 are arranged so that they slide on each other while maintaining the contact state even if the positions of adjacent panel bodies are slightly shifted in the thickness direction as shown in FIG. The contact surface is formed in a curved shape. Accordingly, even in the state of FIG. 8, the contact member 55 of the third panel body 13 pushes the contact member 55 of the fourth panel body 14, and the fourth panel body 14 is moved to the inclined portions 21 c. It can be pushed diagonally along 22c.

  When the fourth panel body 14 is completely displaced in the thickness direction with respect to the third panel body 13 as shown in FIG. 9, the contact between the contact members 55 and 55 is released, and the third panel body 13 is shown in FIG. As shown by the thick line arrow, it can move in parallel to the plane of the fourth panel body 14 and further enter the interior of the door pocket 3. During this parallel movement, the roller 47 at the tip of the connecting arms 45a and 45b slides inside the slide groove 46. During this sliding, the restricting body 48 of the connecting arms 45a and 45b contacts the rotation restricting members 49a and 49b (FIG. 9 shows a state immediately before the contact), so that the connecting arms 45a and 45b are not moved. Smooth slides are realized. Thus, the third panel body 13 and the fourth panel body 14 are stacked in the thickness direction inside the door pocket 3.

  After the entire third panel body 13 enters the interior of the door pocket 3, when the hangers 31 and 32 of the third panel body 13 reach the inclined portions 21c and 22c of the guide rail, this is not shown, but this time The third panel body 13 is pushed by the second panel body 12 and moves in an oblique direction while pushing the fourth panel body 14 inside the door pocket 3. In addition, the 3rd panel body 13 will push the 4th panel body 14 via the said connection arms 45a * 45b which faced the thickness direction. At this time, the rotation of the connecting arms 45a and 45b is restricted by the restricting body 48 and the turning restricting members 49a and 49b, so that the third panel body 13 reliably secures the fourth panel body 14 in the thickness direction. Can be pressed. In this way, the second panel body 12 can also continue to enter the door pocket 3.

  Similarly, when the second panel body 12 enters the interior of the door pocket 3 and the hangers 31 and 32 of the second panel body 12 reach the inclined portions 21c and 22c of the guide rail, the second panel body 12 12 is pushed by the first panel body 11 and moves in an oblique direction inside the door pocket 3 while pressing the third panel body 13 and the fourth panel body 14. As a result, the first panel body 11 can further continue to enter the door pocket 3.

  In this way, the state of FIGS. 10 and 11 in which all of the four panel bodies 11 to 14 are stored inside the door pocket 3 appears. In the following description, the positions of the panel bodies 11 to 14 in FIGS. 10 and 11 may be referred to as “retracted positions”.

  In order to return from the state of FIG. 10 to the state of FIG. 1, the drive unit 4 may be rotated in the opposite direction to that described above, and thus detailed description of the operation is omitted. In this case, the first panel body 11 travels toward the advanced position by pulling the subsequent second panel body 12 through the connecting arms 45a and 45b. Similarly, the second panel body 12 pulls the third panel body 13, and the third panel body 13 pulls the fourth panel body 14.

  As described above, the electric partition device 1 of the present embodiment has a plurality of panel bodies 11 to 14 and the guide rail 21 that guides the panel bodies 11 to 14 so as to be movable between the advanced position and the retracted position.・ 22. Each of the panel bodies 11 to 14 is movable while maintaining its orientation between the advanced position in FIG. 2 and the retracted position in FIG. The panel bodies 11 to 14 are connected to each other, and one panel body (first panel body 11) among them is driven by the drive unit 4 (electric motor) so as to move in conjunction with each other. Yes. And in the advancing position of FIG. 2, the several panel bodies 11-14 are made into the state which followed the linear form, and the several panel bodies 11-14 were piled up in the thickness direction in the retracted position of FIG. It is said that.

  In this configuration, when the panel bodies 11 to 14 that have partitioned the room into two spaces at the advanced position are moved to the retracted position, the panel bodies 11 to 14 are parallel to the linear portions of the guide rails 21 and 22. It is stacked as it is in the direction. Therefore, even if the panel bodies 11 to 14 are retracted, they do not protrude toward the space (see FIG. 2), and therefore, it is difficult for a passerby to get in the way. Moreover, the door pocket 3 which accommodates the panel bodies 11-14 of a retracted position can be formed compactly. Further, since the panel bodies 11 to 14 move while keeping the direction between the advanced position and the retracted position, the movement trajectory can be made compact. Therefore, even if furniture or the like is placed near the panel bodies 11 to 14 at the advanced position, the furniture or the like is not easily disturbed when the panel bodies 11 to 14 are retracted. In addition, by transmitting the driving force of the drive unit 4 (electric motor) that drives one panel body 11 to the other panel bodies 12-14, the four panel bodies 11-14 move in conjunction with each other. Therefore, the configuration for driving the panel bodies 11 to 14 is simplified and the control thereof is also simplified.

  In the present embodiment, the guide rail includes two rails 21 and 22 that are parallel to each other. Each panel body 11 to 14 has a door (first roller 61) on the door-side hanger 31 and the door-side hanger 32, and the door-side door wheel is connected to the first guide rail 21. The door trolleys are supported by the second guide rails 22 respectively. Accordingly, each of the panel bodies 11 to 14 can be stably supported on the door end side and the door bottom side. In addition, by guiding the travel of the roller 61 as a door cart by the guide rails 21 and 22, the panel bodies 11 to 14 can be moved so as to be shifted in the thickness direction while maintaining the direction.

  Further, in the electric partition device 1 of the present embodiment, as shown in FIG. 5 and the like, the two rails 21 and 22 are arranged at different heights. Therefore, it is possible to avoid the interference between the rails 21 and 22 and to prevent the interference between the rollers 61 to 63 on the door end side and the door bottom side.

  Further, as shown in FIG. 2, the guide rails 21 and 22 have linear portions and are configured to be inclined at portions corresponding to the retracted positions of the panel bodies 11 to 14 (inclined portions 21c and 22c). ). Accordingly, when the panel bodies 12 to 14 reach the inclined portion, the panel bodies 11 to 14 are moved along the inclination so as to be shifted in the thickness direction, the subsequent partition is moved to the inclined portion, and so on. Can be stacked one after another in the thickness direction.

  In the present embodiment, the drive unit 4 (electric motor) is connected to the first panel body 11 closest to the door end among the plurality of panel bodies 11 to 14. Therefore, the configuration for driving the plurality of panel bodies 11 to 14 can be further simplified.

  Further, in the present embodiment, in the first panel body 11 closest to the door end, the rollers 61 to 63 of the hangers 31 and 32 do not travel on the inclined portions 21 c and 22 c of the guide rails 21 and 22. That is, the first panel body 11 is simply reciprocated linearly along the linear portions of the guide rails 21 and 22 without sliding in the thickness direction between the advanced position and the retracted position. Yes. The first panel body 11 is fixed to a drive belt 9 driven by the drive unit 4 (electric motor). Therefore, the drive transmission configuration can be simplified using the drive belt 9.

  In this embodiment, the panel bodies adjacent to each other are connected by connecting arms 45a and 45b. When the connecting arms 45a and 45b are adjacent to each other so that their adjacent directions can be changed (FIGS. 7, 8, and 9), and are shifted from each other in the thickness direction. One is connected to the other so that it can slide parallel to the plane of the panel body (thick arrow in FIG. 9). Therefore, adjacent panel bodies can be switched in such a manner that they are adjacent to each other in a straight line at the advanced position (FIG. 2) and adjacent to overlap in the thickness direction at the retracted position (FIG. 11). . When the panel body is displaced in the thickness direction, the panel body can be stacked in the thickness direction by sliding along the plane of the panel body with respect to the other (when moving from the advanced position to the retracted position). ). Conversely, when moving from the retracted position to the advanced position, the overlapping of the panel bodies can be eliminated by the slide.

  Further, one end of each of the connecting arms 45a and 45b is rotatably supported by one panel body, and the other end is slidably connected to the other panel body. Accordingly, the adjacent directions of the panel body can be switched by rotating the connecting arms 45a and 45b, and the other end of the 45a and 45b slides so that one of the panel bodies is in the plane of the panel body with respect to the other. Can slide along. As a result, a simple and rational configuration can be obtained. Moreover, when the panel bodies 11-14 are piled up in the retracted position, the distance between the panel bodies 11-14 in the thickness direction is appropriately maintained by the connecting arms 45a and 45b, and the contact of the panel bodies can be avoided.

  The connecting arms 45a and 45b are rotatably supported at one end on the upper part of one panel body, and the other end is slidable along a slide groove 46 formed on the upper part of the other panel body. It is said that. Therefore, since the connection configuration is disposed on the upper portion of the panel body, the connection configuration can be made inconspicuous, and the design is excellent. In the present embodiment, the connecting arms 45a and 45b and the slide groove 46 are concealed by the ceiling frame 2 even at the advanced position (FIG. 1), so that a clean appearance can be obtained.

  Further, in the present embodiment, as shown in FIG. 7, there are provided a regulating body 48 and rotation regulating members 49a and 49b for limiting the rotation range of the connecting arms 45a and 45b to a range of about 90 °. . The restricting body 48 and the rotation restricting members 49a and 49b are arranged such that when the connecting arms 45a and 45b are substantially oriented in the thickness direction of the panel body (FIG. 9), the further connecting arms 45a and 45b are rotated. Is provided to prevent. Thereby, the play and blurring of the panel body can be reduced. In particular, when the adjacent panel bodies slide along the plane of the panel body, the rotation of the connecting arms 45a and 45b is restricted, so that the panel body can be smoothly slid. Further, when the panel bodies are stacked in the thickness direction at the retracted position, the connection arms 45a and 45b are prevented from rotating while facing the thickness direction of the panel body, so that one panel body is the other panel. The body can be appropriately pushed in the thickness direction via the connecting arms 45a and 45b.

  It should be noted that the number of panel bodies as the partition may be plural, and may be five or more, or two or three. Further, the door may not be provided at the retracted position of the panel body, and the panel body may be exposed to the outside even at the retracted position.

  In addition, the first panel body 11 is not limited to be driven via the drive belt 9, and a drive unit may be provided in the first panel body 11 so as to be a so-called self-propelled type. Even in this case, if the other panel bodies 12 to 14 are not provided with a drive unit and the driving force of the first panel body 11 is distributed to the other panel bodies 12 to 14, the drive configuration can be simplified. it can.
