Hereinafter, one embodiment of the movable partition according to the present invention will be specifically described with reference to the drawings.

First, typical types and structures of the movable partition according to the present invention will be explained. As movable partitions, those having structures shown in FIGS. 39 to 43 are known. Moreover, FIG. 44 shows the support structure of the panel 5a1 of the hinged door of the movable partition shown in FIG. 43.

The movable partition 1 shown in FIG. 39 is made up of a pair of panels 1a, 1a. and the stretched state. The upper stile 1at of each panel 1a is connected to the upper guide rail 1b, and the lower stile 1ab is connected to the lower guide rail 1c and is movable along these guide rails 1b, 1c. Note that the upper guide rail 1b and the lower guide rail 1c are common to each pair of panels 1a, and are different from the other pair of panels 1a. That is, the guide rails 1b and 1c connected to each pair of panels 1a are different. Further, the panel 1a can be freely moved in either the folded state or the extended state. That is, by folding the two panels 1a, it can be used as a folding door, and when it is in an extended state, it can be used as a sliding door. The movable partition 1 that can be used as either a folding door or a sliding door is hereinafter referred to as a "folding/sliding door type." By arranging all the pairs of panels 1a in a stretched state, a partition is formed to divide the room into two rooms. Furthermore, by folding all the pairs of panels 1a and moving them to one or both ends of the guide rails 1b, 1c, the widest frontage is achieved and the room can be used more widely. Furthermore, when one pair of panels 1a is placed in a folded state and the other pair of panels 1a is placed in an extended state, the portion of the first pair of panels 1a in the folded state can be used as a passageway in a partitioned room. In addition, when the room is divided into two rooms, you can enter and exit using the sliding door function. In addition, the panel 1a has an upper stile 1at, a lower stile 1ab, and a stile 1af and a vertical stile 1ap, in which adjacent panels of the vertical stile face each other and form a joining part.

The movable partition 2 shown in FIG. 40 has a pair of two panels 2a, and the two panels 2a constituting the pair are in a folded state and an extended state in which they are stretched into a single plate shape. Displaced between. The upper stile 2at of the panel 2a is connected to the upper guide rail 2b, and the lower stile 2ab is connected to the lower guide rail 2c, and by moving along these guide rails 2b and 2c, the panel 2a is folded. Displaces between the state and the extended state. Note that these upper guide rails 2b and lower guide rails 2c are all shared by the pair of panels 2a, and therefore do not have the function of a sliding door. The movable partition 2 that can be used only as a folding door will be referred to as a "folding door/folding door type" hereinafter. When all the pairs of panels 2a are stretched, they become a partition that divides the room into two rooms. Furthermore, by folding all the pairs of panels 2a and moving them to one or both ends of the guide rails 2b, 2c, the frontage can be maximized. In addition, the panel 2a has an upper stile 2at, a lower stile 2ab, a combined stile 2af, and a vertical stile 2ap.

The movable partition 3 shown in FIG. 41 is a sliding door made of one panel 3a. The upper stile 3at of the panel 3a is connected to the upper guide rail 3b, and the lower stile 3ab is connected to the lower guide rail 3c. Furthermore, all the panels 3a are connected to different guide rails 3b, 3c. The movable partition 3 that can be used only as a sliding door will be referred to as a "sliding door/sliding door type" hereinafter. By arranging all the panels 3a so that they do not overlap, a partition is created to divide the room into two rooms. Further, by stacking all the panels 3a, the stacked panels 3a function as wing walls, and the portion where the panels 3a are not present becomes a passage. The panel 3a has an upper stile 3at, a lower stile 3ab, a combined stile 3af, and a vertical stile 3ap.

The movable partition 4 shown in FIG. 42 is a sliding door made of one panel 4a. In the panel 4a, the upper stile 4at is connected to the upper guide rail 4b, but the lower guide rail to which the lower stile 4ab should be connected has not been laid, and the panel 4a is suspended from the upper guide rail 4b. It is something that Furthermore, all the panels 4a are connected to different upper guide rails 4b. A movable partition 4 that is not provided with such a lower guide rail and can be used only as a sliding door is hereinafter referred to as a "non-rail sliding door type." By arranging all the panels 4a so that they do not overlap, a partition is created to divide the room into two rooms. Further, by stacking all the panels 4a, the stacked panels 4a function as wing walls, and the portion where the panels 4a are not present becomes a passage. The panel 4a includes an upper stile 4at, a lower stile 4ab, a combined stile 4af, and a vertical stile 4ap.

Moreover, the movable partition 5 shown in FIG. 43 includes one panel 5a1 that serves as a hinged door, and the other panels 5a are configured as sliding doors. The panel 5a1 of the hinged door opens and closes by rotating around a support shaft, which will be described later, arranged near the wall. Further, it is provided with a structure in which the other panel 5a can be stored together with the panel 5a1 by, for example, running parallel to the wall surface of the room. In this panel 5a, the upper stile 5at is connected to the upper guide rail 5b, but the lower guide rail to which the lower stile 5ab is connected is not laid, and the panel 5a is suspended from the upper guide rail 5b. It is something that exists. Furthermore, all the panels 5a share the upper guide rail 5b. A storage guide rail 5d is branched in the middle of this upper guide rail 5b, and the upper stile 5at of the panel 5a is also connected to this storage guide rail 5d. The storage guide rail 5d includes a movement guide rail 5d1 branched from the upper guide rail 5b, and a movement guide rail 5d1 that extends from the tip of the movement guide rail 5d1 parallel to the upper guide rail 5b, and is located at the end of the upper guide rail 5b where the storage guide rail 5d is arranged. The storage section rail 5d2 extends in the direction of the end portion of the storage section. For this reason, by positioning one end of the upper stile 5at of the panel 5a on the storage section rail 5d2 and positioning the other end on the end of the upper guide rail 5b, the panel 5a can be almost aligned with the upper guide rail 5b. It becomes perpendicular and parallel to the wall of the room, and is stored along the wall of the room. Note that the movable partition 5 that stores the panel 5a will be referred to as a "movable storage type" hereinafter. When all the panels 5a are pulled out along the upper guide rail 5b and the panel 5a1 is closed, it becomes a partition that divides the room into two rooms. At this time, if the panel 5a1 of the hinged door is opened, it can be used as a passage. The panels 5a and 5a1 include an upper stile 5at, a lower stile 5ab, a combined stile 5af, and a vertical stile 5ap. As shown in FIG. 38, the connecting frame 5af of the panel 5a1 serving as a swinging door has a doorstop frame 5as that abuts against the connecting frame 5af of the panel 5a serving as a sliding door to position the panel 5a1 of the hinged door in the closed position. is provided.

FIG. 44 is an exploded perspective view illustrating a structure that supports the rotation of the panel 5a1 of the hinged door. As mentioned above, the panel 5a1 of the hinged door rotates between the open state and the closed state. Note that FIG. 44 shows the vertical stile 5ap, upper stile 5at, and lower stile 5ab of the panel 5a1, and each of the upper stile 5at and the lower stile 5ab has a gap prevention member 14 and a gap prevention member 15, which will be described later. installed.
An upper stile connecting fitting 5apt for connecting the upper stile 5at is attached to the upper part of the vertical stile 5ap on the rotation axis side of the hinged door panel 5a1, that is, the hinge side, and a lower stile connecting fitting 5apt for connecting the lower stile 5ab to the lower part. 5apb is installed. The upper stile connecting fitting 5apt is provided with an attachment plate portion 5at1 that protrudes toward the upper stile 5at, and the lower stile connecting fitting 5apb is provided with an attachment plate portion 5ab1 that protrudes toward the lower stile 5ab. An upper stile 5at and a lower stile 5ab are attached to the distal end sides of the mounting plate portion 5at1 and the mounting plate portion 5ab1, respectively.
A support shaft 5apa that projects downward is supported by the mounting plate portion 5ab1 of the lower stile connecting fitting 5apb. The tip of the support shaft 5apa is inserted into a shaft hole (not shown) formed in the floor of the room so as to be rotatable about the shaft of the support shaft 5apa.
A support shaft 5ata, which is coaxial with the support shaft 5apa, is supported by the mounting plate portion 5at1 of the upper stile connecting fitting 5apt in a state that projects upwardly. 5br is supported to form a runner.
Further, a runner equipped with a support roller similar to the support roller 5br is also arranged on the upper stile 5at of the panel 5a which is a sliding door connected to the upper guide rail 5b, and the upper guide rail 5b is connected to the upper guide rail 5b via this runner. It is connected with. The panel 5a provided with the upper stile 5at moves along the upper guide rail 5b as a sliding door.
The upper guide rail 5b is extended until it reaches the wall of the room, and a support roller 5br is connected to the end of the upper guide rail 5b on the wall side. Thereby, the upper side of the panel 5a1 is rotatably supported by the support roller 5br, and the lower side is rotatably supported by the support shaft 5apa. That is, by rotating around these support shafts 5apa and 5ata, the panel 5a1 of the hinged door opens and closes.
In this way, the lower stile connecting fittings 5apb and the upper stile connecting fittings 5apt are provided with the supporting shafts 5apa and 5ata, and the vertical stile 5ap is not provided with these supporting shafts 5apa and 5ata. The cross-sectional shape of the stile 5ap can be made smaller. Therefore, by downsizing the hinged door provided with the panel 5a1, the movable partition 5 can be downsized, and the movable partition 5 can be made small enough to be installed in a general house.
Alternatively, the support shaft 5ata may be made longer without providing the support roller 5br, and the tip of the support shaft 5ata may be inserted into a shaft hole formed in the ceiling surface. In the case of this structure, even if a through hole through which the support shaft 5ata passes is formed in the upper guide rail 5b at a position that coincides with the shaft hole, or the upper guide rail 5b does not extend to the wall surface, The end portion may be placed at a position where it does not interfere with the shaft 5ata.

Furthermore, by using the upper stile connecting fittings 5apt in the structure that connects the connecting stile 5af of the panel 5a and the upper guide rail 5b, and the structure that connects the vertical stile 5ap and the upper guide rail 5b, these connecting stile The cross-sectional shapes of the stile 5af and the vertical stile 5ap can be made smaller.
Furthermore, upper stile connecting metal fittings and lower stile connecting metal fittings having the same structure as the upper stile connecting metal fittings 5apt are used to connect the vertical stile, upper guide rail, and lower guide rail of other types of movable partitions. be able to. In particular, the connection of the vertical stile 3ap of the panel 3a of the movable partition 3 called "sliding door/sliding door type", the upper guide rail 3b, and the lower guide rail 3c, and the vertical stile of the movable partition 4 called "non-rail sliding door type" By using it to connect the vertical stile 4ap and the upper guide rail 4b, the cross-sectional shape of the vertical stile 3ap and vertical stile 4ap can be made small, and the movable partition 3 and the movable partition 4 can be made smaller.
In addition, the movable partition 1 called "folding door/sliding door type" and the movable partition 2 called "folding door/sliding door type" also have upper stile connecting fittings and lower stile connecting fittings similar to the upper stile connecting fittings 5apt. By using the vertical stile 1ap, 2ap, the upper guide rails 1b, 2b, and the lower guide rails 1c, 2c can be connected, and the shape of the cross section of the vertical stile 1ap, 2ap can be made small. In this way, in the structure in which the vertical frames 1ap and 2ap are linked to the upper guide rails 1b and 2b and the lower guide rails 1c and 2c via the upper stile connecting fittings and the lower stile connecting fittings, a pair of panels 1a and 2a are connected to each other. In the folded state, these panels 1a and 2a protrude only to one side across the upper guide rails 1b and 2b and the lower guide rails 1c and 2c.

Note that by forming the lateral curved surface of the accommodation tongue piece 10d and the curved inner surface of the holding tongue piece 10b in a continuous spiral shape, the holding part 10c can be made into a shape having a hollow cross section. It can be formed into a spiral shape. The distal end of the accommodation tongue 10d and the distal end of the holding tongue 10b are appropriately spaced apart to form a throat 10f of the holding portion 10c.

On the other hand, a held part 10g that is connected to and held by the holding part 10c is provided on the front wall part of the joining frame 1af, and at the end that becomes inside when folded. There is. The held portion 10g has a neck portion 10g1 that protrudes forward from the front surface of the connecting frame 1af, and is wound such that its tip portion is held by the holding portion 10c, and the holding end portion 10h is formed. Note that, as described above, when the holding part 10c is formed in a spiral shape with a hollow cross section, the held part 10g is a solid body accommodated in the hollow spiral shape of the holding part 10c. By forming the spiral shape, the holding portion 10c and the held portion 10g can be reliably connected.
Further, the neck portion 10g1 of the held portion 10g passes through the throat portion 10f. Furthermore, a locking protrusion 10g2 is provided on a side surface of the neck portion 10g1, which is opposite to the direction in which the holding portion 10c is wound. As shown in FIG. 14, this locking protrusion 10g2 comes into contact with the tip of the accommodation tongue piece 10d of the connecting plate 10, thereby regulating the position of the held part 10g with respect to the holding part 10c, and the panel 1a is It becomes a stretched state.

Further, by providing an appropriate gap between the hollow spiral-shaped holding part 10c and the solid spiral-shaped held part 10g, it is possible to use the shaft part 12b of the shaft member 12 as an axis, as described later. When swinging the joining frame 1af relative to the connecting plate 10, the position of the held portion 10g relative to the holding portion 10c can be smoothly moved.

In order to connect the connecting frame 1af and the connecting plate 10, insert the end of the connecting plate 10 from the end of the connecting frame 1af, and slide the connecting plate 10 in the longitudinal direction of the connecting frame 1af. . At this time, the connecting plate 10 is inserted so that the holding end 10h is held by the holding part 10c.
As a result, the connecting plate 10 and the pair of connecting frames 1af become integrated, and as will be described later, when the connecting frames 1af rotate, the holding end portion 10h is held by the holding portion 10c. It moves within the holding part 10c while maintaining the state.

The shaft member 12 is connected to the connecting plate 10 and the stile cap 11, as shown in FIGS. 5 to 8 and 10. The connection between the connecting plate 10 and the shaft member 12 will be described with reference to FIGS. 6 and 8.
Note that the connecting frame cap 11 and the shaft member 12 are arranged at the upper and lower parts of the connecting frame 1af, respectively. The shaft member 12 is shown. Therefore, the term "upper and lower" in the following description refers to the shaft member 12 and the connecting frame 1af disposed at the upper part.
As shown in FIGS. 6, 8, and 10, the shaft member 12 is mainly composed of a pedestal portion 12a formed in an oval shape. Two shaft portions 12b projecting upward are provided on the upper surface of the pedestal portion 12a. Further, as shown in FIG. 10, a connecting plate receiving portion 12c is provided on the lower surface of the base portion 12a and protrudes downward from one of the long sides of the oval shape of the pedestal portion 12a. The connecting plate receiving part 12c includes a flat plate part 12c1 extending along an ellipse, and a protruding part 12c2 in the center of the flat plate part 12c1, which protrudes toward the other long side of the ellipse. There is. The lower surfaces of the flat plate portion 12c1 and the protruding portion 12c2 are formed into a flat surface and serve as a connecting plate receiving surface 12c3. That is, when the shaft member 12 is connected to the connecting plate 10, the end surface of the connecting plate 10 comes into contact with the connecting plate receiving surface 12c3.
At the center of the connecting plate receiving surface 12c3, a connecting part 12d having a shape that matches the shaft member accommodating part 10e of the connecting plate 10 and having a substantially V-shaped cross section that is inserted into the shaft member accommodating part 10e is provided. There is. As shown in FIGS. 5, 6, and 9, the shaft member accommodating portion 10e of the connecting plate 10 has a cross-sectional shape in which the accommodating tongue piece 10d side is widened, and the cross-sectional shape of the connecting portion 12d The shape is narrow on the flat plate portion 12c1 side, which is the tip side, and the tip side of the flat plate portion 12c1 side is inserted into the main plate 10a side of the shaft member accommodating portion 10e of the connecting plate 10. Further, a retaining plate 12e is provided at the proximal end of the connecting portion 12d, which is the thicker end of the cross-sectional shape. Then, the outer surface of the housing tongue piece 10d of the connecting plate 10 comes into contact with the surface of the holding plate 12e on the connecting portion 12d side. When the connecting plate 10 and the shaft member 12 are connected, the connecting part 12d is inserted into the shaft member accommodating part 10e of the connecting plate 10, and as described above, the front end surface of the connecting plate 10 is placed in the connecting plate receiving part. It comes into contact with the surface 12c3.

The matching frame cap 11 is formed of a box, and the outer shape of its side plate is shaped to approximately match the outer shape of the matching frame 1af. Note that FIGS. 5 to 8 show a state in which the connecting frame caps 11 attached to the respective connecting frames 1af of the pair of panels 1a are connected.
The top surface of the matching stile cap 11 substantially coincides with the top surface of the upper stile 1at when it is attached to the matching stile 1af. Moreover, a gap prevention material attachment groove 11a is provided on the top surface, into which a gap prevention member to be described later is attached. The lower side of the stile cap 11 is a space in the box, and ribs are appropriately arranged in this space to ensure strength, as shown in FIGS. 7 and 8. There is. Further, on the lower side of the matching stile cap 11, shaft holes 11b are provided into which the shaft portions 12b of the shaft member 12 are respectively inserted.
Teeth 11c are formed on opposing parts of the outer circumferential surface of the matching stile caps 11, and these teeth 11c mesh with each other in a state where the pair of matching stile caps 11 are connected. When the connecting plate 10 is connected to the connecting frame 1af and the connecting frame cap 11 is placed on the connecting frame 1af, as shown in FIGS. 5 and 7, the shaft portion 12b is inserted into the shaft hole 11b, and each The teeth 11c of the matching stile cap 11 will mesh with each other.

FIG. 13 shows a matching stile cap 111 having a different shape from the above-mentioned matching stile cap 11. Note that each of the matching stile caps 111 that are placed over the pair of panels 1a has a tooth portion 111c similar to the tooth portion 11c of the matching stile cap 11. FIG. 13 is a plan view, with some parts omitted, showing a state in which these teeth 111c are engaged with each other. (A) shows a state in which the pair of panels 1a are in a folded state, and (B) and (C) (D) shows a state where one panel 1a is in an extended state.
In the above-mentioned stile cap 11, as shown in FIG. 11, when the panel 1a is in an extended state, the front surfaces of the side where the teeth 11c are not formed are in close contact with each other, or there is a slight gap on the end side. It is said to have a shape that can be formed. For this reason, there is a risk that the tips of the fingers and toes may be caught between the matching stile caps 11, and in particular, there is a risk that the tips of the toes may be caught between the lower matching stile caps 11.
On the other hand, the matching stile cap 111 shown in FIG. 13 prevents the fingertips of hands and feet from being accidentally pinched.
On the front surface of each of the matching frame caps 111, a tooth portion 111c is formed on one end side, and a portion on the other end side where the tooth portion 111c is not formed is shown in FIG. 13(D). Thus, an outer plane 111a, which is substantially parallel when the panel 1a is in an extended state, is formed at an appropriate position extending from the ends to the center. A pinch prevention gap Ga is formed by the space between the outer planes 111a. On the other hand, an inner plane 111b is formed from the root of the tooth portion 111c, which is located on the central side of the front side of the matching stile cap 111, to an appropriate position. These inner plane surfaces 111b are arranged to come into close contact with each other when the panel 1a is in an expanded state, as shown in FIG. 13(D).
Then, an inclined surface 111d formed by a plane in a direction intersecting each of the outer plane 111a and the inner plane 111b is connected to the end of the outer plane 111a on the center side and the edge of the inner plane 111b on the center side. There is. That is, this inclined surface 111d widens on the outer plane 111a side from the end of the inner plane 111b to the end of the outer plane 111a. Note that a space portion with an appropriate interval is also formed between the inclined surfaces 111d, and this space portion also constitutes a part of the pinch prevention gap Ga.
Note that the pinch prevention gap Ga can also be formed by widening the width from the end of the inner plane 111b on the center side to the end of the outer plane 111a on the center side, without providing the inclined surface 111d.

Therefore, as shown in FIG. 13(B), when the fingertip F is located between the connecting frame caps 111 and the panel 1a is rotating toward the extended state, the fingertip F is exposed to the inclined surface 111d. Upon contact, a force is applied in a direction that narrows the inclined surface 111d, and the fingertip F is pushed out, and the fingertip F can be quickly retracted by sensing that there is a risk that the fingertip F may be pinched. Furthermore, even if the rotation of the panel 1a continues to the extended state, the fingertip F can be pinched by appropriately making the distance between the outer planes 111a of the pinch prevention gap Ga larger than the fingertip F. Never.

Furthermore, as shown in the cross-sectional views of FIGS. 14 and 15, the matching frame 1af is provided with a finger hook 1af1 having a side wall protruding rearward at a side end portion on the back side. Further, as shown in FIG. 19, a front side finger hook portion 1ap1 that bulges out laterally is formed at the side end portion on the front side of the vertical stile 1ap. Further, a back side finger hook portion 1ap2 is provided at the side end portion on the back side of the vertical stile 1ap so as to protrude laterally.

(Displacement operation of folding door)
The displacement operation of the folding door between the folded state and the extended state will be described with reference to FIGS. 11 to 18.
FIGS. 11 and 14 are diagrams showing a case where a pair of panels 1a of the folding door/sliding door type movable partition 1 are in an extended state. Moreover, FIGS. 16 and 17 show the movement of the joining frame 1af relative to the connecting plate 10 as the pair of panels 1a changes from the folded state to the extended state. That is, FIG. 16(A) shows the extended state, which gradually swings and changes to the folded state shown in FIG. 17(C).
In the extended state shown in FIGS. 11, 14, and 16(A), the two panels 1a are arranged in the same straight line and form a single plate, which can function as a sliding door. Moreover, FIG. 11 is a plan view of the two panels 1a, and FIG. 14 is a cross-sectional view of the joining frame 1af of the two panels 1a. Moreover, FIG. 16 and FIG. 17 are cross-sectional views of the joining frame 1af. Moreover, since the pair of panels 2a of the folding door/folding door type movable partition 2 has the same structure as the panel 1a, the panel 1a will be explained. In addition, in the case of the movable partition 2, the panel 2a does not function as a sliding door.
As shown in FIGS. 11 and 13, the matching stile caps 11 and 111 that are placed on the matching stile 1af of the two panels 1a have teeth 11c and 111c formed thereon meshing with each other, as shown in FIGS. 11 and 13. . Note that the following description will be made regarding the matching stile cap 11. Further, as described above, the connecting stile cap 111 functions to prevent the fingertips F from getting caught when moving from the folded state to the extended state.
When the two panels 1a are in a stretched state, as shown in FIGS. 14 and 16(A), the outer surface of the main plate 10a of the connecting plate 10 and the side surface of the connecting frame 1af are in the same plane. To position. Further, the gap formed between the connecting frames 1af is closed by the gap prevention member 13 provided at the end opposite to the side connected to the connecting plate 10. In addition, as shown in FIG. 14, FIG. 16, and FIG. 17, the gap prevention member 13 attached to one side of the facing matching frame 1af and the gap prevention member 13 attached to the other side are reversed and combined. It is preferable to form a space 13b between the tongue pieces 13a of the gap prevention member 13.
12, FIG. 15, FIG. 16(B), FIG. 16(C), FIG. 17(A), and FIG. 17(B) show that the two panels 1a are in the middle of displacement between the folded state and the extended state. From this state, the panel 1a is further folded and the two panels 1a are in a parallel state, resulting in the folded state shown in FIG. 17(C).

In order to displace the two panels 1a in the stretched state to the folded state, the joining frame 1af is moved in the direction indicated by the arrow P in FIGS. 11, 14, and 16(A). At this time, when operating from the connecting plate 10 side, the connecting frame 1af is pushed in the direction shown by the arrow P. When operating from the side of the gap prevention member 13, the fingertip of the hand is hooked to the finger hook portion 1af1 and moved in the direction of the arrow P by pulling it toward the user.
When the connecting frame 1af moves in the direction of the arrow P, each of the two panels 1a swings around a connecting portion between the upper frame 1at and the upper guide rail 1b, which will be described later. Due to this swinging, the joining frame 1af is moved to the side of the upper guide rail 1b, and the connecting portion between the upper frame 1at of the two panels 1a and the upper guide rail 1b is moved closer to each other. When the matching frames 1af move in the direction of the arrow P, each of the matching frames 1af swings about the shaft portion 12b of the shaft member 12, respectively.

In order to shift from the extended state to the folded state, as shown in FIGS. 16 and 17, when the connecting frame 1af swings around the shaft portion 12b of the shaft member 12, the inside of the holding portion 10c of the connecting plate 10 is moved. The held portion 10g of the meeting frame 1af moves.
In the extended state, as shown in FIG. 16(A), the held part 10g is located at the innermost part of the held part 10c, and the locking protrusion 10g2 of the held part 10g is in contact with the tip of the housing tongue piece 10d of the connecting plate 10.
When displacing from the extended state to the folded state, the held portion 10g gradually moves relative to the holding portion 10c. Since the connecting frame 1af on which the held portion 10g is arranged swings about the shaft portion 12b of the shaft member 12, in order for the connecting frame 1af to be allowed to swing relative to the connecting plate 10, , the held part 10g must be allowed to move relative to the holding part 10c. As described above, when the holding part 10c is formed in a hollow spiral shape and the held part 10g is formed in a solid spiral shape connected to this holding part 10c, a gap may be left between them. By forming this, both the movement of the holding part 10c with respect to the held part 10g and the swinging of the joining frame 1af with respect to the connecting plate 10 are allowed.
When the held part 10g moves relative to the holding part 10c, the held part 10g moves in a direction in which it gradually separates from the holding part 10c. Further, the moving direction of the held portion 10g is a direction in which the locking protrusion 10g2 of the held portion 10g is separated from the tip of the accommodation tongue piece 10d. In the folded state shown in FIG. 17(C), the held portion 10g is separated from the holding portion 10c to the most protruding position. Even in this state, the joining frame 1af and the connecting plate 10 are connected so that the held part 10g does not separate from the holding part 10c. Therefore, in order to connect the connecting frame 1af and the connecting plate 10, as described above, the end of the connecting plate 10 is held from the end of the connecting frame 1af to the holding part 10c of the connecting plate 10. The holding end 10h is inserted so as to be held, and the connecting plate 10 is brought together and slid in the longitudinal direction of the stile 1af.
Moreover, at this time, the tooth portions 11c formed on the pair of matching stile caps 11 rotate around the shaft portion 12b, and the meshing state is maintained, so that the pair of matching stile caps 11 Rotate in sync.

In order to displace the two panels 1a in the folded state to the extended state, the vertical stile 1ap of one panel 1a is moved in a direction away from the vertical stile 1ap of the other panel 1a. As a result, the matching stile cap 11 swings around the shaft portion 12b of the shaft member 12, and the two panels 1a rotate synchronously due to the meshing relationship of the teeth 11c. 1a is in an expanded state. At this time, when the held part 10g moves within the holding part 10c and reaches the extended state as shown in FIG. come into contact with

Further, when displaced to the extended state, the engagement receiving portion 16b enters the position between the pair of engagement portions 16a as shown in FIG. 18, and the engagement portion 16a and the engagement receiving portion 16b engage match. When the engagement ball 16a1, which partially protrudes from the engagement portion 16a, passes the edges of the upper and lower surfaces of the engagement receiving portion 16b, the engagement ball 16a1 resists the restoring force of a pressing spring (not shown) It embeds itself inside the cylinder and scrapes both the upper and lower surfaces. When this engagement ball 16a1 reaches the ball receiving portion 16b1 of the engagement receiving portion 16b, the engaging ball 16a1 is received in the ball receiving portion 16b1 by the restoring force of the pressing spring, and the engaging portion 16a and the engagement receiving portion 16b and are engaged. When the engaging portions 16a and the engaging receiving portions 16b are engaged, the interlocking frames 1af are locked to each other, and the extended state is maintained.
In order to displace the two panels 1a in the stretched state into the folded state, as described above, the joining frame is moved by receiving a force in the direction indicated by the arrow P in FIGS. 11, 14, and 16(A). 1af rotates. This rotation releases the engagement between the engaging ball 16a1 and the ball receiving portion 16b1, allowing the panel 1a to be folded. To release the engagement between the engaging ball 16a1 and the ball receiving portion 16b1, the engaging ball 16a1 is released from the ball receiving portion 16b1 by rotating the joining frame 1af. At this time, the engagement ball 16a1 is buried in the cylindrical body of the engagement part 16a against the restoring force of a pressing spring (not shown), so that the engagement between the engagement part 16a and the engagement receiving part 16b can be released. becomes. When the engagement ball 16a1 separates from the upper and lower surfaces of the engagement receiving portion 16b, it protrudes from the engagement portion 16a due to the restoring force of the pressing spring.

In addition, the two panels 1a in the extended state can function as a sliding door, but in that case, as shown in FIG. The panel 1a can be moved along the upper guide rail 1b and the lower guide rail 1c by gripping the panel 1a or by hooking the fingertips on the back finger hook 1ap2 as shown in FIG. 19(C). can.

As mentioned above, the folding structure of the folding door is such that the connecting frames 1af of the two panels 1a are connected via the connecting plate 10, and the connecting frames 1af of each panel 1a are connected to the connecting plate 10. By swinging, it can be freely displaced between a folded state and an extended state. Since the connecting plate 10 is vertically connected to the connecting frame 1af, there is no gap between the upper and lower sides of the connecting frame 1af.
The panel 1a swings as the matching stile cap 11 disposed on the matching stile 1af rotates around the shaft portion 12b of the shaft member 12. That is, the connecting plate 10, the connecting frame cap 11, and the shaft member 12 can cause the connecting frame 1af to swing, and the structure is simple and the number of parts is reduced. Rocking can be easily performed in synchronization.
Moreover, even if the connecting frame 1af swings relative to the connecting plate 10, the held portion 10g does not fall off from the holding portion 10c.
In addition, when the two panels 1a are in an extended state, the outer surface of the main plate 10a of the connecting plate 10 and the side surface of the joining frame 1af can be positioned in the same plane, so that when the two panels 1a are in the extended state, , there are no outwardly protruding parts, and the appearance is not impaired.
Further, when the pair of panels 1a are in the stretched state, the front faces of the joining frames 1af of the two panels 1a are positioned opposite to each other, and a gap is formed between these joining frames. When the folded state is changed to the extended state, the presence of the gap prevention member 13 prevents fingers or the like from being caught in the gap. Moreover, in the extended state, this gap is closed by the gap prevention member 13, so this gap does not appear on the exterior of the movable partition 1, and the exterior appearance of the movable partition 1 is not impaired.
Further, by using a flexible material such as a rubber material for the gap prevention member 13, even if a finger hits it, it will bend appropriately and will not give an impact. Note that it is preferable that the gap prevention member 13 be formed of a hollow body because it can reduce the weight.
When the panel is in an extended state, it is used when the room is divided into two rooms, so it would be inconvenient if it were folded carelessly. For this reason, a locking means consisting of an engaging portion 16a and an engaging receiving portion 16b for locking the matching frames together is provided so that the extended state can be maintained. Preferably, this locking means is removable so that the panel can be folded by being released from the locking device with an appropriate force.
In addition, by providing finger hooks 1af1, front side finger hooks 1ap1, and back side finger hooks 1ap2 on the connecting stile 1af and vertical stile 1ap of the panel 1a, the folding door of the movable partition 1 can be displaced or moved as a sliding door. It is possible to have the child perform the following tasks without any problem.
On the other hand, generally, as shown in FIGS. 39, 41, and 42, the panel 1a of the movable partition 1 can be operated by providing handles 1ah, 3ah, and 4ah on the vertical stile 1ap, etc. It is set as. In this embodiment, the panel 1a of the movable partition 1 can be installed without providing such a handle 1ah, etc., but it is preferable, for example, that the handle 1ah etc. can be attached at the user's request. .
Note that if a handle or the like is not attached, the panel can be made smaller, and the movable partition can be made smaller.

(Panel support structure and connection structure between upper and lower stile and guide rail)
When a panel 1a having a small wall thickness is used, there is a possibility that the surface of the panel 1a may be bent as shown by the arrow S in FIG. 20(B) when a force is applied to the surface of the panel 1a. In particular, when downsizing the movable partition 1 for installation in a general house, the upper stile 1at, the lower stile 1ab, the combined stile 1af, and the vertical stile 1ap are downsized, and the thin panel 1a is used. Therefore, there is a possibility that the panel 1a may be bent by a slight force. Therefore, when the panel 1a is about to curve, a structure is required that allows this curve and restores it to its original state.

20 to 22 are longitudinal cross-sectional views showing the structure of the connecting portion between the panel 1a, the upper stile 1at, and the upper guide rail 1b, and the connecting portion between the panel 1a, the lower stile 1ab, and the lower guide rail 1c.
The panel 1a is held with its upper and lower ends supported by the lower wall of the upper stile 1at and the upper wall of the lower stile 1ab.

As shown in FIG. 21, a support groove 1at1 is formed in the lower wall of the upper stile 1at in the longitudinal direction of the upper stile 1at, and the upper end of the panel 1a is inserted into this support groove 1at1. Further, a cushioning material 1ad having appropriate elasticity is disposed in the support groove 1at1, and the end of the panel 1a and the support groove 1at1 are connected via the cushioning material 1ad. Therefore, the panel 1a is allowed to tilt as appropriate with respect to the upper stile 1at.
The upper stile 1at is provided with an upper shaft 1at2 whose axial direction is in the vertical direction, and the upper end of this upper shaft 1at2 projects above the upper stile 1at. On the other hand, a pair of rollers 1b1 that can freely roll in the longitudinal direction are arranged on the upper guide rail 1b. This roller 1b1 is rotatably supported around a support shaft 1b3 supported by a support block 1b2, and as a result of this rotation, it is guided by the upper guide rail 1b and rolls. Further, the direction of the support shaft 1b3 of these rollers 1b1 and the axial direction of the upper shaft 1at2 are perpendicular to each other, and the upper end of the upper shaft 1at2 is rotatably supported by the support block 1b2. This rotation of the upper shaft 1at2 relative to the support block 1b2 causes the panel 1a to be displaced between the folded state and the extended state. Further, a flange portion 1at21 is formed at the upper part of the upper shaft 1at2, and a gap Gt is provided between this flange portion 1at21 and the lower surface of the support block 1b2. It is permitted to tilt at an appropriate angle with respect to the direction perpendicular to the axis.
Further, a pair of gap prevention members 14 are provided at the side ends of the upper surface of the upper stile 1at so as to sandwich the upper shaft 1at2, and the tips of these gap prevention members 14 are brought close to the upper guide rail 1b. , the gap formed between the upper stile 1at and the upper guide rail 1b is closed. Further, the gap prevention member 14 is made of a material such as rubber and has flexibility.

As shown in FIG. 22, a support groove 1ab1 is formed in the upper wall of the lower stile 1ab in the longitudinal direction of the lower stile 1ab, and the lower end of the panel 1a is inserted into this support groove 1ab1. Further, a cushioning material 1ae having appropriate elasticity is disposed in the support groove 1ab1, and the end of the panel 1a and the support groove 1ab1 are connected via the cushioning material 1ae. Therefore, the panel 1a is allowed to tilt as appropriate with respect to the lower stile 1ab.
The lower stile 1ab accommodates a spring casing 1abb formed in a cylindrical shape with a bottom, and a pressure spring 1ab2 made of a compression coil spring is accommodated in this spring casing 1abb. The spring housing 1abb has a bottom at the top and an opening 1abb1 at the bottom, and the pressure spring 1ab2 is appropriately held and housed in the upper part, that is, the bottom of the spring housing 1abb. A lower shaft 1ab3 is accommodated in this spring housing 1abb, and the tip of this lower shaft 1ab3 protrudes from the opening 1abb1. Further, the lower shaft 1ab3 is slidable in the axial direction with respect to the spring housing 1abb. A pressure spring 1ab2 is detachably connected to the base end of the lower shaft 1ab3, and when engaged, the restoring force of the pressure spring 1ab2 is applied in the direction in which the lower shaft 1ab3 protrudes from the spring housing 1abb. energized.
Note that the spring housing 1abb and the lower shaft 1ab3 may be used as a so-called telescopic shaft that is freely extendable and retractable, and a pressure spring 1ab2 may be provided on the outer cylinder of the shaft.
At the tip of the lower shaft 1ab3, a slider 1d is connected to the lower guide rail 1c, and the lower shaft 1ab3 and the slider 1d are connected with an appropriate play, that is, an appropriate gap. The lower shaft 1ab3 is supported rotatably around the lower shaft 1ab3. Furthermore, the slider 1d is pressed against the lower guide rail 1c by the restoring force of the pressing spring 1ab2. A rail portion 1c1 having a dovetail cross section is provided on the upper surface of the lower guide rail 1c, and a dovetail rail groove portion 1d1 for accommodating this rail portion 1c1 is formed at the lower part of the slider 1d. ing. Further, in a state where these rail portions 1c1 are accommodated in the rail groove portion 1d1, an appropriate gap Gb is provided between the inner surface of the rail portion 1c1 and the outer surface of the rail groove portion 1d1.
Further, the connecting portion of the lower shaft 1ab3 with the slider 1d is formed in a reduced diameter shape, and a gap Gs is provided between the end of the lower shaft 1ab3 on the enlarged diameter side and the slider 1d. Therefore, these gaps Gb and Gs allow the lower shaft 1ab3 to tilt with respect to the slider 1d, and the slider 1d to tilt with respect to the lower guide rail 1c.
Furthermore, a pair of gap prevention members 15 are provided at the side ends of the lower surface of the lower stile 1ab so as to sandwich the lower shaft 1ab3, and the tips of these gap prevention members 15 are brought close to the lower guide rail 1c. Thus, the gap formed between the lower stile 1ab and the lower guide rail 1c is closed. Further, this gap prevention member 15 is made of a material such as rubber and has flexibility.

The upper axis 1at2 and the lower axis 1ab3 described above are arranged on the same axis. In addition, in each of the two panels 1a of the movable partition 1 of the folding/sliding door type, a connecting portion consisting of the upper shaft 1at2 and the lower shaft 1ab3 is arranged at one location of the upper stile 1at and the lower stile 1ab. has been done. Furthermore, the respective connecting portions of the two panels 1a are provided at symmetrical positions with the aforementioned connecting plate 10 as an axis.
In addition, in each of the two panels 2a of the folding door/folding door type movable partition 2, an upper shaft 1at2 and a lower shaft 1ab3 are similarly arranged at one location of the upper stile 2at and the lower stile 2ab. There is.
The upper shaft 1at2 is rotatable relative to the support block 1b2, and the lower shaft 1ab3 is rotatable relative to the slider 1d. Therefore, the upper shaft 1at2 and the lower shaft 1ab3 are rotatable with respect to the upper guide rail 1b that accommodates the support block 1b2 and the lower guide rail 1c that engages with the slider 1d. There is. Therefore, in the case of a folding door, when rotating the panel 1a to displace it between the folded state and the extended state, the panel 1a can be rotated about the upper axis 1at2 and the lower axis 1ab3. become.

In addition, in the case of the movable partition 3 and movable partition 4 that only have a sliding door function that does not function as a folding door, and the panel 3a, panel 4a, and panel 5a used for the movable partition 5, the upper axis 1at2 and the lower axis 1ab3 is preferably provided at multiple locations.

Furthermore, since the gap prevention member 14 and the gap prevention member 15 are attached, a finger may be inserted into the gap between the upper stile 1at and the upper guide rail 1b or the gap between the lower stile 1ab and the lower guide rail 1c. This will be prevented. In particular, there is a risk that a toe may be inserted into the gap between the lower stile 1ab and the lower guide rail 1c, and for this reason, it is preferable to provide at least a gap prevention member 15 in the lower stile 1ab. Furthermore, it is also preferable that the interval between the lower stile 1ab and the lower guide rail 1c is set to a size that does not allow a toe to be inserted.
In addition, by providing the gap prevention member 14 and the gap prevention member 15 with flexibility using a rubber material or the like, even if a finger butts against them, they will bend appropriately and will not give an impact.

(Operation when the panel is curved)
When a force such as an impact is applied to the central portion of the panel 1a, the panel 1a will curve as shown in FIG. 20(B).
At this time, since the panel 1a is supported by the upper stile 1at via the cushioning material 1ad and by the lower stile 1ab via the cushioning material 1ae, the impact is alleviated by these cushioning materials 1ad and 1ae, and the shock is cushioned. The material 1ad is crushed to allow the panel 1a to curve. Furthermore, the gap Gt provided between the flange portion 1at21 of the upper shaft 1at2 and the support block 1b2 allows the upper shaft 1at2 to tilt with respect to the upper guide rail 1b. Furthermore, the gap Gb provided between the slider 1d attached to the lower shaft 1ab3 and the lower guide rail 1c allows the lower shaft 1ab3 to tilt with respect to the lower guide rail 1c. Furthermore, the gap Gs provided between the lower shaft 1ab3 and the slider 1d allows the lower shaft 1ab3 to tilt with respect to the slider 1d.
Therefore, the curvature of the panel 1a is allowed by tilting the upper axis 1at2 and the lower axis 1ab3.
Furthermore, when the panel 1a curves, the distance between the upper stile 1at and the lower stile 1ab becomes smaller. Therefore, the upper stile 1at and the lower stile 1ab move in a direction toward each other. Since the position of the upper stile 1at is restricted in relation to the upper guide rail 1b, the upper stile 1at does not move, but the lower stile 1ab moves diagonally upward as shown in FIG. 20(B). Approach the upper stile 1at. Note that this movement of the lower stile 1ab diagonally upward is allowed by the gap Gb between the lower guide rail 1c and the slider 1d. Further, this movement of the lower stile 1ab diagonally upward is caused by the spring housing 1ab sliding in the axial direction with respect to the lower shaft 1ab3. Therefore, the bottom of the spring housing 1abb and the tip of the lower shaft 1ab3 are separated from each other, so that the biasing state caused by the restoring force of the pressing spring 1ab2 against the slider 1d is released.

When the force caused by the impact on the panel 1a disappears, the curved panel 1a returns to its flat shape due to its restoring force. By this return operation, the upper shaft 1at2, which is tilted with respect to the upper guide rail 1b due to the gap Gt, returns to its original state. Further, the slider 1d tilted with respect to the lower guide rail 1c returns to its original position due to the gap Gb, and further, the lower shaft 1ab3 tilted with respect to the slider 1d returns to its original position.
Further, the lower stile 1ab, which has been raised to approach the upper stile 1at, is lowered and returns to its original position. At this time, the spring housing 1abb slides on the lower shaft 1ab3, and the lower stile 1ab descends. This lowering of the spring housing 1abb causes the pressure spring 1ab2 to engage with the lower shaft 1ab3, and the restoring force of the pressure spring 1ab2 is brought into a state where it acts on the slider 1d. Therefore, the slider 1d is pressed by the lower guide rail 1c, and the slider 1d is in a state where it can be guided by the lower guide rail 1c and move.

(Sliding door stopper device)
When using the panel 1a of a movable partition 1 of a folding door/sliding door type as a sliding door, or when using the panel 3a of a movable partition 3 of a sliding door/sliding door type as a partition, the panel 1a or panel 3a is It may be necessary to fix it in place. For example, when one pair of panels 1a in an extended state is used as a sliding door for entry and exit, it is preferable that the other pair of panels 1a be fixed so as not to move inadvertently. Moreover, in the case of the movable partition 3, it is preferable that one panel 3a is used as an entrance and exit, and the other panels 3a are fixed.
For this purpose, a stopper device is attached to the lower end of the vertical stile 1ap of the panel 1a. 23 to 29 show a stopper device 20 suitable for a movable partition 1 and a movable partition 3 equipped with a lower guide rail 1c, and FIGS. 30 to 34 show a stopper device 20 suitable for a movable partition 1 and a movable partition 3 equipped with a lower guide rail 1c. A stopper device 30 suitable for case 5 is shown.

The stopper device 20 is preferably provided in the movable partition 1 shown in FIG. 39 and the movable partition 3 shown in FIG. 41, and the structure described below is for the stopper device 20 provided in the movable partition 1. However, the stopper device 20 provided in the movable partition 3 can also have a similar structure.

The stopper device 20 mainly includes a holder member 21, an operating member 22 as a pin holding member, a locking pin 23, and a pin receiving receptacle 24 as a pin receiving hole.
The holder member 21 is inserted and attached to the lower end of the vertical stile 1ap of the panel 1a. The front surface of this holder member 21 is exposed and arranged in front of the lower end of the vertical stile 1ap. A pair of guide holes 21a are formed on the left and right sides of the holder member 21, passing through in the vertical direction. Further, as shown in FIGS. 25 and 27, a locking notch 21b is formed at the upper center of the back surface, which is cut from the upper end to an appropriate position downward. Further, a recess 21c serving as an operation section is provided on the front surface of the holder member 21 and is recessed toward the rear side, and a lower portion of the recess 21c is open at the lower surface of the holder member 21.
On the other hand, the actuating member 22 includes a pair of guide columns 22a that are inserted into the guide holes 21a, and the guide columns 22a are slidable with respect to the guide holes 21a. The guide column 22a is erected on the base plate 22d of the actuating member 22, and has a height that prevents it from accidentally separating from the guide hole 21a even during the operation described later.

A portion of the pin holding plate 23a projects from the side of the actuating member 22, and a locking pin 23 is provided in this projecting portion so as to project downward.
Further, a through hole 1ca is formed in a part of the lower guide rail 1c corresponding to the position where the panel 1a is to be fixed, and a pin receiving receptacle 24 is buried in this through hole 1ca. .

The stopper device 30 shown in FIGS. 30 to 34 also has the same structure as the stopper device 20, and is mainly composed of a holder member 31, an operating member 32, and a locking pin 33. This stopper device 30 is suitable for a structure without a lower guide rail, such as a movable partition 5, and instead of the pin receptacle 24 provided in the stopper device 20, pins can be placed at predetermined positions on the floor. A receiving hole (not shown) is provided.

The holder member 31 is inserted and attached to the lower end of the vertical stile 5ap of the panel 5a, and the front surface of the holder member 31 is exposed in front of the lower end of the vertical stile 5ap. A guide column 32a standing upright on the base plate 32d of the actuating member 32 is slidably inserted into a guide hole 31a formed in the holder member 31. A spring plate portion 32b is provided on the back side of the base plate 32d. A locking notch 31b formed on the back surface of the holder member 31 and a locking protrusion 32c that is engaged and disengaged due to the flexibility of the spring plate 32b protrude from the upper part of the spring plate 32b. Note that the holder member 31 is provided with an insertion hole 31d, and the spring plate portion 32b is inserted through the insertion hole 31d.
Further, the upper surface of the base plate 32d of the actuating member 32 is exposed to the recessed portion 31c, which is the operating portion of the holder member 31. Further, on the front side of the actuating member 32, a recessed portion 32e is provided at the lower part of the base plate 32d on the back side as an operating portion.

(Operation of stopper device)
When the panel 1a is movable, the base plate 22d of the actuating member 22 is in contact with the lower surface of the holder member 21. In this state, the locking protrusion 22c is engaged with the locking notch 21b, the actuating member 22 is held by the holder member 21, the locking pin 23 is in the raised position, and the pin receiver It is in a position where it does not engage with the pot 24. A position where the locking pin 23 is not engaged with the pin receiving pot 24 is defined as a movement permissible position.
When fixing the panel 1a in a predetermined position, the panel 1a is moved to a position where the locking pin 23 faces the pin receptacle 24. Then, when the fingertip is inserted into the recess 21c and the base plate 22d is pushed down, the actuating member 22 is lowered relative to the holder member 21. At this time, as the spring plate portion 22b is bent, the locking protrusion 22c is disengaged from the locking notch 21b, and the actuating member 22 is allowed to descend. Since the holder member 21 is held by the vertical stile 1ap, when the operating member 22 descends, the locking pin 23 also descends and engages with the pin receptacle 24. The engagement between the locking pin 23 and the pin receptacle 24 prevents movement of the panel 1a, and the panel 1a is fixed at the position. The position where the locking pin 23 engages with the pin receptacle 24 is defined as a movement blocking position.

To release the engagement between the locking pin 23 and the pin receptacle 24, insert a fingertip into the recess 22e at the bottom of the base plate 22d of the actuating member 22 and raise the actuating member 22 relative to the holder member 21. . As a result, the locking pin 23 is disengaged from the pin receptacle 24, and the engaged state thereof is released. Further, when the locking protrusion 22c reaches the locking notch 21b by raising the actuating member 22, the spring plate portion 22b in the bent state uses its restoring force to move the locking protrusion 22c into the locking notch. Since the actuating member 22 is engaged with the portion 21b, the actuating member 22 will be held by the holder member 21 from now on, and the actuating member 22 will not be inadvertently lowered. This allows the panel 1a to be moved.

In the case of the stopper device 30, when the fingertip is inserted into the recess 31c and the base plate 32d is pushed down, the actuating member 32 is lowered relative to the holder member 31, and the locking pin 33 is formed on the floor. The panel 5a is engaged with a pin receiving hole that is not connected to the movement preventing position, and the movement of the panel 5a is prevented.
Further, when the actuating member 32 is pushed up by inserting a fingertip into the recess 32e, the locking pin 33 is disengaged from the pin receiving hole, the engaged state of these is released, and the actuating member 32 is located at the movement permissible position. Furthermore, when the locking projection 32c reaches the locking notch 31b, the locking projection 32c engages with the locking notch 31b due to the restoring force of the bent spring plate portion 32b, and the actuating member 32 locks into the holder. It will be in a state where it is held by the member 31. Thereby, the panel 5a can be moved without the actuating member 32 inadvertently detaching from the holder member 31.

Since the operation of activating the actuating member 22 to move the locking pin 23 between the movement permissible position and the movement inhibiting position can be performed from the front of the vertical stile 1ap, the holder member that guides the movement of the actuating member 22 is 21 can be housed and provided in the vertical stile 1ap. Therefore, the stopper device 20 can be downsized, the vertical stile 1ap can be downsized, the movable partition 1 can be downsized, and the movable partition 1 can be made small enough to be installed in a general house. can do.

(Structure to prevent shaking of non-rail sliding door)
In the non-rail sliding door type movable partition 4, no lower guide rail is installed, the upper stile 4at is suspended from the upper guide rail 4b, and the lower stile 4ab is in a free state. For this reason, when force is applied from the side of the panel 4a, etc., there is a possibility that the panel 1a swings left and right around the connecting portion between the upper stile 1at and the upper guide rail 4b. If the panel 4a swings, the function as the movable partition 4 may be impaired, so it is preferable to prevent this swing.
Therefore, it is preferable that the non-rail sliding door type movable partition 4 is provided with a swing prevention function. The anti-sway structure that performs this anti-swing function will be described below.

FIG. 37 is a front view of the panel 4a of the non-rail sliding door type movable partition 4. 35 is a perspective view of the floor guide 40, and FIG. 36 is a perspective view of the panel guide 42. Note that a pair of gap prevention members 15 are attached to the lower stile 4ab of the panel 4a.
As shown in FIG. 35, the floor guide 40 includes a support plate portion 40a fixed to the floor surface, and a locking portion 40b projecting upward from one end of the support plate portion 40a. The support plate portion 40a is provided with a through hole 40a1 through which a fixing bolt or the like is inserted when fixing to a floor surface. A cushioning material holding part 40b1 whose width is smaller than that of the lower part is formed at the upper part of the locking part 40b, and as shown in FIG. 40c is retained.
The panel guide 42 is formed of a strip material in a substantially U-shape, and one arm of the U-shape is longer than the other arm. The arm on the extended side is used as a support arm 42a, and the arm on the short side is used as a locking arm 42b. The support arm 42a is fixed to the side surface of the stile 4ap of the joining part of one panel 4a that overlaps as a sliding door, and the locking arm 42b engages with the other panel 4a. The support arm portion 42a is provided with a through hole 42a1 through which a fixing bolt or the like is inserted when fixing to the panel 4a. A cushioning material holding portion 42b1 whose width is smaller than that of the lower portion is formed at the upper part of the locking arm portion 42b, and as shown in FIG. The material 42c is held.
For example, in a non-rail sliding door type movable partition 4 made up of two panels 4a, the two panels 4a are suspended from different upper guide rails 4b and have different movement trajectories. Therefore, the two panels 4a can overlap in the entire area, and when dividing the room into two rooms as a partition, the vertical frames 4ap of the two panels 4a overlap at the joint.

FIG. 37 is a vertical cross-sectional view showing a joint section when divided into two rooms, and a floor guide 40 is fixed to the floor surface of the part where the vertical stile 4ap of one panel 4a of this joint section is located. . When the support plate part 40a of the floor guide 40 is fixed to the floor surface, the locking part 40b stands up upward. In this state, the cushioning material holding portion 40b1 is located between the pair of gap prevention members 15 attached to the lower stile 4ab of the panel 4a that moves above the floor guide 40. Note that, as shown in FIG. 37, it is preferable to form a recess 4ab1 along the longitudinal direction on the lower surface of the lower stile 4ab and the vertical stile cap 4ap1 so that the cushioning material 40c can be inserted into this recess 4ab1.
The panel 4a passing above the floor guide 40 moves with the cushioning material holding part 40b1 connected between the gap prevention members 15 and the recessed part 4ab1. Therefore, when the panel 4a passing above the floor guide 40 attempts to swing, the cushioning material 40c of the cushioning material holding portion 40b1 comes into contact with the gap prevention member 15 and the recess 4ab1, thereby preventing the panel 4a from swinging. Further, the shock generated at the time of contact is alleviated by the cushioning material 40c.

A support arm 42a of a panel guide 42 is fixed to a side surface of a vertical stile 4ap of one panel 4a that passes above the floor guide 40. The U-shaped center portion of this panel guide 42 extends toward the other panel 4a, and the locking arm portion 42b is positioned between the gap prevention members 15 of the other panel 4a. Further, it is preferable that a recess 4ab1 is also formed on the lower surface of the lower stile 4ab of the other panel 4a, so that the cushioning material 42c is inserted into the recess 4ab1.
The panel 4a passing above the cushioning material holding portion 42b1 of the panel guide 42 moves with the cushioning material holding portion 42b1 being connected between the gap prevention members 15 and the recessed portion 4ab1. Therefore, when the panel 4a passing above the cushioning material holding portion 42b1 of the panel guide 42 attempts to swing, the cushioning material 42c of the cushioning material holding portion 42b1 comes into contact with the gap prevention member 15 and the recessed portion 4ab1 and the swinging is prevented. thwarted. Further, the shock generated at the time of contact is alleviated by the cushioning material 40c.
