Various mobile partition devices that can be rotated 90 degrees at the side end portions are provided. This type of movable partitioning device is a one-side end portion of the rail, and the movable panel is rotated 90 degrees so that the panel surface is orthogonal to the rail, and the surfaces are overlapped and stored compactly. And a mode in which the moving panel is rotated 90 degrees and pulled out from one end of the rail along the rail, each moving panel is connected in a straight line, and the large room is divided into small rooms To do.

  In Patent Document 1, a moving panel (door) is suspended on a guide rail attached to a ceiling so as to be movable by a guide roller provided at an upper end thereof, and the moving panels are arranged in a straight line. A structure is disclosed in which the space between the lower surface and the floor surface is closed. That is, a pair of elevating plates are provided on both sides of the lower open frame provided at the lower end of the movable panel so as to be movable up and down, and one end projects from the side end surface and is elastically biased in the projecting direction. The L-shaped actuating arm bends in a vertically long slot formed in the frame body, one end pivotally attached to the operating rod, and the other end to the lifting plate When the movable panel is pivotally attached and the moving panel stops against the wall surface or the side end surface of the other movable moving panel, the protruding portion of the operating rod is pushed in, and the lifting plate is lowered in conjunction with the lateral movement of the operating rod. The cushioning material provided on the lower surface of the closing body connected between the lower ends of the two lifting plates is in contact with the floor surface.

  In Patent Document 2, a guide member movable along a guide rail provided on the ceiling is provided at least at the front and rear ends of the upper end of the movable panel (panel unit) so as to be movable in the vertical direction. The lower end is provided with a pair of front and rear casters that can move on the floor, and a moving panel elevating means. When the moving panel is raised by operating the elevating means, the caster protrudes from the lower end of the moving panel. A movable panel device is disclosed in which the lower end of the movable panel is in contact with the floor surface when the movable panel is lowered by touching the floor surface. Here, the elevating means is accommodated in the lower end portion of the movable panel so as to be movable up and down, and a movable plate provided with a pair of casters on the lower surface, and an upper and lower portion linked to the middle portion of the movable plate to move the movable plate up and down. A structure including a toggle link mechanism composed of a pair of links and an operation lever capable of bending and extending the toggle link mechanism from the outside of the moving panel, or an elevating means, is provided in the lower end portion of the moving panel so as to be movable up and down.

Abut The movable partition device is characterized in that the baseboard member is positioned immediately below the panel body in a state where the baseboard member is lowered by the reaction force and is pressed against the floor surface. An apparatus was configured (claim 1).

  Further, in order to solve the above-mentioned problems, the present invention travels on the floor surface with a rolling wheel provided at the lower end portion of the moving panel, and a guide roller or a guide slider provided at the upper end portion of the moving panel is provided on the ceiling. A movable partition device that moves and guides along the guide rail, linearly aligns the plurality of moving panels along the guide rail, and then lifts the rolling wheels by a lift mechanism to enter a movement restricted state, The lift mechanism is provided with a rolling wheel at the lower end of the panel body of the movable panel so as to protrude downward from the panel body, and a baseboard member is swingably raised and lowered by a parallel link. In a state where the rolling wheel is in contact with the floor surface, the tip of one end of the baseboard member protrudes from the side end surface of the panel body, and the baseboard member descends to cause the rolling wheel to move to the floor surface. Emerged from In it are state constitutes a movable partition device, characterized in that is adapted to position just below 該巾 wood member of the panel body (claim 2).

  Here, the lift mechanism forms a parallel link by pivotally attaching a fixing member attached to the lower surface of the panel body and the baseboard member with a pair of link members, and the fixing member and the baseboard member An intermediate member is disposed between the intermediate members and pivotally attached to the intermediate portion of the link member. The rolling wheel is attached to the lower surface of the intermediate member, and the rolling wheel can protrude downward from the lower end of the baseboard member. (Claim 3).

  Further, the baseboard member is a long channel member having a substantially U-shaped cross section opened upward, and when the baseboard member is raised, the intermediate member and the fixing member can be sequentially received inside the concave groove. In addition, it is preferable that an opening through which the rolling wheel can pass is provided on the bottom plate of the baseboard member (Claim 4).

  Further, the link member has a rectangular block shape in a side view, and a bearing tool in which an upper end corner portion of the link member corresponding to a direction side in which a distal end portion of the baseboard member protrudes is attached to the fixing member is used. It is preferable that the parallel link is constructed by pivotally attaching the diagonal portion of the lower end corner portion of the link member using a bearing tool attached to the bottom plate of the baseboard member. 5).

  The intermediate member has an opening that penetrates the link member and does not interfere with the movement of the intermediate member, and is pivotally attached to the upper edge of the link member by a rotary damper at the edge of the opening. (Claim 6).

In particular, the operation when changing from the movement restricted state to the movable state becomes gentle.

  According to claim 7, from the movable state where the baseboard member is raised, the end of the baseboard member abuts against the wall or the side end face of the other movable panel aligned in advance, and the impact force is used. The baseboard member is lowered by the parallel link, and at that time, the initial lowering operation of the baseboard member is assisted to ensure a smooth operation.

  As shown in FIGS. 2 and 3, the mobile partition device according to the present invention travels on the floor surface F with rolling wheels 2 provided at the lower end portion of the movable panel 1 and is provided at the upper end portion of the movable panel 1. The guide roller 3 is guided to move along the guide rail 4 provided on the ceiling S, and a plurality of moving panels 1 are arranged along the guide rail 4 and overlapped with one end portion of the guide rail 4. It has a structure of a lower load system in which it is stored and the entire surface from the ceiling S to the floor surface F can be closed or opened. In the present invention, in a state where the plurality of moving panels 1,... Are arranged along the guide rail 4, the lift mechanism 5 provided at the lower end is operated to restrict the movement of the moving panel 1. The movable panel 1 is raised, and the rolling wheels 2 are lifted from the floor F.

  Here, the guide rail 4 has a pair of parallel hanging plates 6 and 6 on at least both front and rear surfaces, and an upper open concave groove portion 7 for receiving the hanging plates 6 and 6 is formed at the upper end of the movable panel 1. At the same time, sliders 9 that are in sliding contact with the outer surface of the hanging plate 6 are provided on the inner surfaces of the compatible wall portions 8 and 8 that form the concave groove portion 7, respectively. Although a guide slider can be used instead of the guide roller 3, it is preferable to use the guide roller 3 in order to move the moving panel 1 smoothly. The sliders 9 and 9 may be provided on the outer surfaces of the both hanging plates 6 and 6 of the guide rail 4 and may be in sliding contact with the inner surfaces of the compatible wall portions 8 and 8 forming the concave groove portion 7. From this point of view, it is preferable to provide the inner surfaces of the compatible walls 8 and 8 as in the present embodiment.

  More specifically, the guide rail 4 is a long member having a substantially U-shaped cross section with a hanging plate 6, 6 provided from both side edges of the upper plate 10 and facing the inner surfaces of the hanging plates 6, 6. A pair of sliding pieces 11, 11 projecting over the entire length, and a guide roller 3 having a vertical rotating shaft 12 projecting upward from the inside of the concave groove 7 at the lateral center of the movable panel 1. The guide roller 3 is held so as to be able to roll above the sliding pieces 11 and 11 between the hanging plates 6 and 6.

  The guide rail 4 is formed of a long aluminum extrusion mold material in which the sliding pieces 11 and 11 are formed at the upper and lower intermediate positions of the hanging plates 6 and 6, and the direction changing portion A corresponding to the one end portion. And the other series holding part B, and both the hanging plates 6 and 6 below the sliding pieces 11 and 11 of the direction changing part A are cut out to form a notch part 13. Is in a vertical posture and the rolling wheel 2 is in contact with the floor surface F, the sliders 9, 9 of the standing wall portions 8, 8 of the movable panel 1 are in sliding contact with the hanging plates 6, 6 of the series holding portion B, and The height is set so that the standing wall portions 8 and 8 of the movable panel 1 are lower than the hanging plates 6 and 6 of the direction changing portion A.

  Thereby, in a state where the movable panel 1 is in a vertical posture and the rolling wheels 2 are in contact with the floor surface F, the vertical walls 8 and 8 of the movable panel 1 are placed on the hanging plates 6 and 6 of the series holding portion B of the guide rail 4. Since the sliders 9 are in sliding contact with each other, the movable panel 1 can be stably linearly moved along the guide rail 4 without rotating, and the plurality of movable panels 1 can be aligned on a straight line. (See FIG. 1 (a)). In the direction changing portion A of the guide rail 4, the notch portion 13 is formed in the direction changing portion A, and the height is set so that the standing wall portions 8 and 8 of the movable panel 1 are lower than the hanging plates 6 and 6. Therefore, the movable panel 1 can be rotated around the vertical rotation shaft 12 (see FIG. 1C). In this way, in the direction changing section A of the guide rail 4, the movable panels 1,... Can be rotated one after another and stacked in parallel with each other so as to be stored compactly (FIG. 1 (d) and FIG. e)).

  Here, an opening / closing panel 14 that can be horizontally rotated to secure a space for receiving the moving panels 1,... Provided. The open / close panel 14 is pivotally attached to the position immediately below the guide rail 4 in the vicinity of the wall surface W at the upper and lower ends of one side. Further, the length of the direction changing unit A is the same as that of the last moving panel 1 except that the last moving panel 1 is stored and the other moving panels 1,. It is set so that it can be rotated in the remaining space of the conversion unit A. That is, the length L of the remaining direction changing portion A with the open / close panel 14 open is such that L> (N when the number of the movable panels 1,... Is N, the lateral width is D, and the thickness is T. -1) It is set to satisfy T + D.

  Then, as shown in FIGS. 4A and 4B, a synthetic resin block body 15 having an elliptical shape in plan view is mounted in the recessed groove portion 7 of the movable panel 1, and the rotation shaft of the guide roller 3 is mounted. 12 is provided so as to penetrate through the block body 15, and the block body 15 can be slid below the sliding pieces 11, 11 between the both hanging plates 6, 5 of the guide rail 4. More specifically, the guide roller 3 is rotatably provided at the upper end portion of the rotating shaft 12 that passes through the center hole 16 of the block body 15, and is provided at the lower surface of the block body 15 and the lower end of the rotating shaft 12. A compression coil spring 18 is interposed between the engaging portion 17 and the locking portion 17 to unitize the mechanism portion.

  Then, in the state in which the rotating body 12, the guide roller 3, the locking portion 17, and the compression coil spring 18 are combined with the block body 15 into a unit, the bottom plate 19 of the concave groove portion 7 of the movable panel 1 is used as the center of the panel width The locking portion 17 and the compression coil spring 18 are both inserted from above into the opening 20 formed in the portion and positioned inside the panel, and the block body 15 is inserted into the bottom plate 19 from above with screws 21,. Fasten. Here, since the compression coil spring 18 is compressed with respect to the upward movement of the guide roller 3 with respect to the block body 15, an elastic resistance force due to the repulsive force is provided. Since the guide roller 3 is locked to the sliding pieces 11 and 11 of the guide rail 4, it rolls along the guide rail 4 at the same height position, but as shown in FIG. In this case, the center of gravity of the movable panel 1 is lowered and the compression coil spring 18 is pressed and contracted. However, the movable panel 1 is automatically brought into a vertical posture by elastic resistance. It acts to restore.

  Then, as shown in FIG. 6, in order to stably maintain the posture of the movable panel 1 moved to a predetermined position, the lift mechanism 5 provided at the lower end of each movable panel 1 is operated and pressed against the floor surface F. The rolling wheel 2 is lifted from the floor surface F. Further, when the movable panel 1 located at the direction changing portion A of the guide rail 4 is lifted by the lift mechanism 5, the standing wall portions 8 and 8 of the movable panel 1 become higher than the hanging plates 6 and 6, Since the sliders 9, 9 provided at the edges stop against the hanging plates 6, 6, the rotation is restricted. Note that the movable panels 1,... Positioned in the series holding part B are always in positions where the sliders 9, 9 abut against the hanging plates 6, 6 of the guide rail 4.

  Next, a first embodiment of the lift mechanism 5 shown in FIGS. 6 to 9 and a second embodiment of the lift mechanism 5 shown in FIG. 10 will be described. First, the basic configuration of the lift mechanism 5 common to both embodiments will be described. The lift mechanism 5 is provided with rolling wheels 2 at the lower end of the panel main body 22 of the movable panel 1 so as to protrude downward from the panel main body 22, and with a parallel link 23 at the lower end of the panel main body 22. In a state where the member 24 is provided so as to be able to swing up and down and the baseboard member 24 is raised and the rolling wheels 2 are in contact with the floor F, the tip 24A at one end of the baseboard member 24 is a panel. In the state where the baseboard member 24 protrudes from the side end surface of the main body 22 and the rolling wheels 2, etc. are lifted from the floor surface F, the baseboard member 24 is positioned immediately below the panel main body 22. It has become. In the first embodiment, the rolling wheels 2,... Are incorporated into the lift mechanism 5 to be movable. In the second embodiment, the rolling wheels 2,... Are fixedly attached to the lower end of the panel body 22. The basic operation is the same although it is different in the point.

  6 (a) and 7 (a), the movable panel 1 is moved from the side from which one end of the baseboard member 24 protrudes to the guide rail 4 in a state where the baseboard member 24 is raised. When the projecting tip 24A of the baseboard member 24 is moved along the wall surface W or the side end face (actually the baseboard member 24) of the other moving panel 1 aligned in advance, the parallel link is moved. 23, the baseboard member 24 is lowered and comes into contact with the floor surface F (see FIG. 7B). After the baseboard member 24 comes into contact with the floor surface F, the inertial force and the lateral pushing force due to the movement of the movable panel 1 are converted by the parallel link 23 into a force that raises the panel body 22. Finally, the panel body 22 is positioned directly above the baseboard member 24 and closely contacts the wall surface W or the side end surface of the other movable panel 1 aligned in advance (FIG. 6B and FIG. 6). 7 (c)). In this state, the load of the panel body 22 acts to maintain the parallel link 23 in a metastable state at the top dead center.

  Next, the first embodiment will be described in more detail with reference to FIGS. The lift mechanism 5 according to this embodiment includes a fixing member 25 attached to the lower surface of the panel body 22 and the baseboard member 24 pivotally connected to each other by a pair of rectangular link members 26, 26 in a side view. 23, an intermediate member 27 is disposed between the fixing member 25 and the baseboard member 24, and is pivotally attached to an intermediate portion of the link members 26, 26. A driving wheel 2 is attached. The fixing member 25 and the intermediate member 27 are long flat members and are shaped to overlap each other. The baseboard member 24 is a long channel member having a substantially U-shaped cross section opened upward. When the baseboard member 24 is raised, the intermediate member 27 and the fixing member 25 are placed inside the concave groove 28. Can be accepted in order. At that time, the bottom plate 29 of the baseboard member 24 is provided with an opening 30 through which the rolling wheels 2 can pass.

  Here, the upper end corner portion of the link member 26 corresponding to the direction in which the distal end portion 24A of the baseboard member 24 protrudes is pivotally attached using a bearing tool 31 attached to the fixing member 25, and the link The diagonal portion of the lower end corner portion of the member 26 is pivotally attached using a bearing tool 32 attached to the bottom plate 29 of the baseboard member 24 to constitute the parallel link 23, and the parallel link 23 is When the dead point, that is, the link member 26 rises, it is in a metastable state. Further, the intermediate member 27 is provided with an opening 33 so as not to interfere with the movement of the link member 26, and a rotation damper 34 is provided at the edge of the opening 33 above the middle of the link member 26. It is pivotally attached to. Accordingly, the vertical movement distance by the parallel link 23 is longer for the baseboard member 24 than for the intermediate member 27, and as a result, the rolling wheel 2 appears and disappears from the opening 30 of the baseboard member 24. The reason why the intermediate member 27 is pivotally attached to the rotary damper 34 is to alleviate the rapid movement of the parallel link 23. Further, a spiral coil spring 35 is provided on the bottom plate 29 in the concave groove 28 of the baseboard member 24. The spiral coil spring 35 may be another elastic body such as a compression coil spring or a leaf spring as long as it can elastically bias the baseboard member 24 downward.

  In the lift mechanism 5, the baseboard member 24, the fixing member 25, and the intermediate member 27 are connected to each other by a parallel link 23, and the rolling wheels 2 are attached to the intermediate member 27 as a unit. As shown in FIG. 8 and FIG. 9, the fixing member 25 is attached and mounted in a downwardly open concave groove portion 36 formed in the lower end portion of the panel main body 22.

  In the movable state of the movable panel 1 shown in FIGS. 7A and 8, the link members 26 and 26 of the parallel link 23 fall down to the side, the intermediate member 27 overlaps the fixed member 25, and both members rise. It is accommodated in the concave groove 28 of the baseboard member 24, and the leading end portion 24 </ b> A of the baseboard member 24 protrudes laterally from the side end face of the panel body 22. In this state, the spiral coil spring 35 is compressed between the bottom plate 29 of the baseboard member 24 and the side surface of the link member 26. Then, when the movable panel 1 is moved along the guide rail 4 from the side having the distal end portion 24A, the distal end portion 24A is abutted against the wall surface W or the side end surface of the other movable panel 1 aligned in advance. Then, a counterclockwise rotational force acts on the link member 26, and the panel main body 22 moves forward while the baseboard member 24 descends. Eventually, the baseboard member 24 contacts the floor surface F as shown in FIG. Touch. Here, the spiral coil spring 35 assists the initial operation of the base plate member 24, and further assists with a kick spring 37 provided around the shaft portion of the bearing tool 32 to ensure a smooth operation. Further, the link member 26 rotates until the panel main body 22 moves forward and comes directly above the baseboard member 24. Accordingly, the intermediate member 27 rises and the rolling wheels 2,. It floats up from the floor surface F (see FIGS. 7C and 9). In this state, the link member 26 rises vertically, and the end surface on the short side is in a metastable state where it contacts the bottom plate 29 of the baseboard member 24 and the lower surface of the fixing member 25. In this state, Counterclockwise rotation is reliably restricted, and clockwise rotation is accompanied by an increase in potential energy so that it does not rotate easily. Similarly, the other movable panels 1 are sequentially aligned in a state where they are abutted against the side end surfaces of the movable panels 1 that have been aligned in advance.

  As shown in FIGS. 7C and 9, the movable panel 1 is moved from the state where the base plate member 24 is pressed against the floor D and the rolling wheels 2,. 4, when storing by moving along the side of the panel main body 22, the metastable state of the parallel link 23 is broken, and the link member 26 rotates clockwise by the weight of the panel main body 22. However, the intermediate member 27 descends, and the rolling wheels 2,. Then, the link member 26 is further rotated by the weight of the panel body 22 and the baseboard member 24 is pulled up. Finally, the movable state shown in FIGS. 7A and 8 is obtained.

  Finally, a second embodiment will be described based on FIG. The lift mechanism 5 of the present embodiment is configured to connect the baseboard member 24 and the fixing member 25 with a pair of link members 26 and 26 to form a parallel link 23, and to fix the rapid operation of the baseboard member 24. A rotary damper 38 is attached to the lower surface of the member 25, and a lower end of a stay 39 having one end fixed to the rotary shaft of the rotary damper 38 is pivotally attached to the upper surface of the bottom plate 29 of the baseboard member 24 using a bearing tool 40, Further, a tension coil spring 41 for raising the baseboard member 24 after the rolling wheels 2,... Are grounded to the floor F is engaged between the bottom plate 29 of the baseboard member 24 and the lower surface of the fixing member 25. It is a worn structure.

  In the case of this embodiment, as shown in FIG. 10A, the base plate member 24 is pulled up by the elastic force of the tension coil spring 41, and downward from the opening 30 of the bottom plate 29 of the base plate member 24. The protruding rolling wheels 2,... Come into contact with the floor surface F, and the movable panel 1 becomes movable. In this state, the distal end portion 24 </ b> A of one end of the baseboard member 24 protrudes from the side end surface of the panel body 22. Then, when the movable panel 1 is moved along the guide rail 4 and the distal end portion 24A hits the wall W or the side end surface of the other movable panel 1 aligned in advance, the elastic force of the tension coil spring 41 is applied. On the contrary, the baseboard member 24 is lowered in parallel by the parallel link 23 and eventually comes into contact with the floor surface F (see FIG. 10B). Then, when the movable panel 1 further moves, the panel body 22 rises so as to ride on the baseboard member 24, and the rolling wheels 2, ... are lifted from the floor surface F (see FIG. 10 (c)). . This state is a metastable state of movement restriction, and the movable panel 1 can be stably aligned and installed.

  In both of the above-described embodiments, the baseboard member 24 serves as a member that presses against the floor surface F and a member to be actuated. In particular, only the upper portion of the movable panel 1 can be operated without operating the baseboard member 24. It is possible to realize the movement restricted state and the movable state simply by pushing the guide rail 4 along the guide rail 4. When the baseboard member 24 is grounded to the floor surface F and the rolling wheels 2,... Are lifted, the baseboard member 24 literally closes the gap between the panel body 22 and the floor surface F as a baseboard. In addition, since the panel main body 22 is positioned immediately above the baseboard member 24, a sense of unity without a sense of incongruity in appearance can be obtained.
