The rail member 11 is parallel to the rail portion 51 and has the same length. The upper surface of the rail member 11 is provided as an additional track 11X. See FIG. 4, FIG. 5, and FIG. On the rear side of the upper part of the support bracket 10, rollers 15 and 16 (running bodies) that are vertically separated are rotatably supported. The outer periphery of the roller 15 has a fitting groove 15a having a circular cross section, and can be fitted to the rail portion 51 and the fixed rail 39. The above-described engaging surface 10a is formed between the rollers 15 and 16 on the rear surface of the support bracket 10 on the left side when viewed from the front. The right support fitting 10 does not have this engagement surface 10a. ,

Next, the support bracket 20 formed at the center of the lower edge of the sliding door 3 will be described with reference to FIGS. 13, 14 (C) and 15. The support bracket 20 includes a vertical plate-shaped fixing portion 20 a fixed to the rear surface of the sliding door 3, a horizontal portion 20 b extending horizontally rearward from the center of the fixing portion 20 a, It has an upright portion 20c erecting from the rear end of the horizontal portion 20b, a pair of protrusions 20d projecting left and right from the upper end of the upright portion 20c, and a rail portion 20e. ing. A guide groove 20 f having the same shape as the guide groove 70 a of the auxiliary rail 70 is formed in the rail portion 20 e.

A roller 25 (running portion) having a vertical rotation axis is rotatably mounted on the upper surface of the horizontal portion 20b of the support bracket 20. The supporting bracket 20 and the roller 25 constitute a sub-running body 29.

The operation of the opening / closing device having the above configuration will be described. First, a description will be given of a state in which all four openings 2X are closed by sliding doors 3 as shown in FIG. In this state, the upper and lower edges of the sliding door 3 are in contact with the upper frame 1c and the lower frame 1d of the frame 1 or are close to each other with a small gap therebetween. The front of sliding door 3 is located on the same vertical plane and is flush.

When the sliding door 3 is in the closed position, the roller 15 on the upper side of the supporting bracket 10 rides on the supporting surface 5 1 y of the rail portion 51 of the rotating link 50, whereby the sliding door 3 is turned into a pair of turns. It is suspended and supported by the dynamic link 50. The lower roller 16 is in contact with the lower surface of the rail portion 51 or confronts it with a slight gap.

The rotation link 50 is urged rearward by the elastic force of the torsion panel 55, and as a result, as shown in FIGS. 2A and 7A, the rail portion of the rotation link 50 Five 1 is maintained at a first position above the upper frame 1c of the frame 1. The rotation of the rotation link 50 backward is prevented by a stopper (not shown) installed behind the rotation link 50 in the upper frame portion 1c. Note that the rearward rotation of the rotation link 50 may be prevented by the sliding door 3 hitting the frame 1. As shown in Fig. 1 (A), when all the sliding doors 3 are closed, the rail members 11 of the support bracket 10 are aligned with the fixed rail 39 fixed to the force frame 1. The additional track 11X of the plurality of rail members 11 and the fixed track 39X of the plurality of fixed rails 39 constitute an intermittent track M that is straight. See Figure 5

When the sliding door 3 is in the closed position, the support fitting 20 provided at the center of the lower edge of the sliding door 3 is accommodated between the pair of guide plates 72. The left and right projections 20 d of the support bracket 20 are located near the upper ends of the inclined grooves 7 2 b of the left and right guide plates Ί 2 facing each other across the gap 71, and thus, the front and rear of the lower edge of the sliding door 3. Shaking in the direction is prohibited. The guide groove 20 f of the rail portion 20 e of the support bracket 20 coincides with the notch groove 2 a of the guide plate Ί 2, and the notch groove 7 a of the auxiliary rail 70 is inserted through the notch 7 2 a. It is linked to 0a. Next, the opening operation of one selected sliding door 3, for example, the second sliding door 3 from the left will be described. As shown in FIGS. 1 (B), 2 (B), 6 and 7 (B), the sliding door 3 is gripped by the handle 3a and pulled out to the front opening preparation position. At this time, through the engagement between the roller 15 of the sliding door 3 and the rail portion 51 of the rotating link 50, the rotating link 50 is rotated forward against the torsion panel 55. As a result, the rail member 11 of the sliding door 3 is disengaged from the fixed rail 39, and the rail portion 51 of the rotating link 50 reaches the second position instead, and forms the same straight line as the fixed rail 39. As the rotation link 50 rotates from the first rotation position to the second rotation position, the upper surface of the rail portion 51 supporting the roller 15 is moved from the support surface 5 y to the auxiliary track 5 1. Change to X.

When one sliding door 3 is in the opening preparation position, the continuous track M in a straight line corresponds to the fixed track 39 x of the four fixed rails 39 and the above sliding door 3 in the opening preparation position 2 The auxiliary track 51X of the rail portion 51 of the book and the additional track 11X of the rail member 11 of the other three sliding doors 3 will be constructed. Further, the rotation of the rotation link 50 further forward is stopped by a stopper (not shown) installed in front of the rotation link 50 in the upper frame portion 1c. When the sliding door 3 moves from the closed position to the open preparation position while being supported by the rotating link 50, it is also displaced downward. Along with this, the support bracket 20 is guided by the guide surface 7 2 X of the pair of guide plates 72, and the pair of left and right projections 20 d of the support bracket 20 is inclined by the left and right guide plates 72. It moves diagonally forward along groove 72b and reaches notch 72c. In this way, the sliding door 3 can move to the preparation position in which the lower edge portion is stably opened. When the sliding door 3 reaches the opening preparation position and the projection 29 d of the support bracket 20 enters the notch 72 c, the roller 25 of the support bracket 20 corresponds to the guide groove 72 a of the guide plate 72. And the rail portion 20 e of the support bracket 20 comes off the sub rail 70. Next, the sliding door 3 is opened and moved from the preparation position to the left or right opening position. At this time, the roller 15 of the support fitting 10 is separated from the auxiliary track 5 lx of the rail portion 51 of the rotating link 50. When the sliding door 3 is moved to the right as shown in FIG. 1 (C), the roller 15 of the upper right bracket 15 is connected to the rail member 11 of the supporting bracket 10 of the sliding door 3 on the right side. Transfer to additional track 1 1 X and then to fixed track 39 X on fixed rail 39. The roller 15 of the left supporting bracket 10 moves from the auxiliary track 51X of the rail portion 51 to the fixed track 39X of the fixed rail 39 next to the right. As is clear from this, the fixed track 39X and the additional track 111X of the closed sliding door 3 constitute a main track 100 for the sliding door 3 that opens. Further, the fixed rail 39 and the rail member 11 of the sliding door 3 in the closed position constitute a main rail having the main track 100.

In the open position of the sliding door 3 herein, from the position the sliding door 3 with open openings 2 _X partially, any position in the range of up to overlap the other of the sliding door 3 in the left and right edge positions Say

When the sliding door 3 is moved from the opening preparation position to the left and right opening positions as described above, the rail portion 51 of the rotating link 50 is maintained at a position which is on the same straight line as the fixed rail 39. More specifically, when the sliding door 3 is in the closed position and the rollers 15 of the left and right support brackets 10 are engaged with the rail portions 51 of the left and right pivot links 50, FIG. 11 (A) As shown in the figure, the front edge of the slider 62 of the holding mechanism 60 provided on the left rotating link 50 is in contact with the engaging surface 10a of the support fitting 10, and the compression coil spring 63 Then in the retracted position. At this time, the follow- Is located at the intersection of the first portion 66a and the second portion 66b of the cam hole 66 of the slider 62, and the locking opening 61 is the end face of the rail portion 51. It is in the retracted position, which is almost flush with. ·

Even if the sliding door 3 moves to the opening preparation position, the above-mentioned maintenance mechanism 60 is maintained in the above-mentioned state. When the bow I door 3 moves to the left or right from the opening preparation position, as shown in Fig. 11 (B), the left or right edge of the engaging surface 10a of the support bracket 10 moves the slider 62. When the follower pin 67 is temporarily pressed, the follower pin 67 temporarily reaches the front end position of the first portion 66 a of the cam hole 66 of the slider 62. When the sliding door 3 is further moved, as shown in FIG. 11 (C), the slider 62 is released from the pressing state by the engagement surface 10a of the support fitting 10, and projects forward. Accordingly, the follower pin 67 relatively moves from the first portion 66a of the cam hole 66 along the second portion 66b, and reaches the rear end of the second portion 66. In this process, the engaging opening 61 protrudes from the end face of the rail portion 51 and fits into the locking recess 31 b formed on the end face of the cylindrical portion 31 of the support bracket 30. As a result, the rail portion 51 of the left pivot link 50 is maintained coaxial with the fixed rail 39. Since the right rotation link 50 is connected to the left rotation link 50 via the interlocking shaft 40, the rail portion 51 of the right rotation link 50 is also fixed to the fixed rail 3. Maintained coaxially with 9.

As a result, even if one sliding door 3 moves toward the open position, the auxiliary track 51X of the rotating link 50 corresponding to this sliding door 3 remains as a part of the intermittent track M, and the sliding door 3 Can move freely from one end of the continuous track M to the other, and the load of the sliding door 3 can be received by the portion of the continuous track M on which the rollers 15 ride.

When the sliding door 3 moves from the opening preparation position to the left or right opening position, the rollers 25 of the lower support bracket 20 pass through the notches 7 2 a of the guide plates 7 2 and the guide grooves 7 of the sub rail 70. 0a and travel along this guide groove 70a. When the sliding door 3 is in the open preparation position and the open position, the support bracket 20 releases the constraint of the guide plate 72. The roller 25 of the support bracket 20 freely travels along the rail portion 20 e of the support bracket 20 of the other sliding door 3, the notch 70 a of the guide plate 70, and the auxiliary rail 70. .

The sliding door 3 in the open position can be moved to the left and right to return to the open preparation position, and then pushed backward to return to the closed position. Rotating phosphorus as described above Since the rail portion 51 of the door 50 is coaxially locked with the fixed rail 39, the roller 15 of the sliding door 3 can be received when the sliding door 3 opens and returns to the preparation position. When the sliding door 3 reaches the opening preparation position, the leading edge of the slider 62 of the holding mechanism 60 is pushed by the support bracket 10 and fitted on the engaging surface 10a, thereby determining the position of the sliding door 3. And the locked state of the rotation link 50 by the maintenance mechanism 60 is released. When three or more sliding doors 3 are provided as in the present embodiment, when one sliding door 3 is in the open position, the other sliding door 3 is similarly opened from the closed position to the open preparation position, and opened. It can be moved from the preparation position to the open position. Therefore, the two sliding doors 3 can be replaced with the initial position.

In the present embodiment, partitions of various lengths are arranged by aligning various components, that is, the support brackets 10 and 20, the rotating link 50, the support bracket 30, and the pipe 35, with the sliding door 3 as a unit. It can be easily formed. The short auxiliary rails 70 located at the left and right ends of the partition and the guide plate 72 fixed to the auxiliary rails 70 may be omitted. In this case, the sliding doors 3 at both ends are guided by one guide plate 72 in the process of moving from the closed position to the open preparation position.

The upper end of the inclined groove 172b is connected to a short vertical groove 172a extending upward, and the lower end is connected to a short notch 172c extending vertically. This notch 17 2 c extends through the lower edge of the guide plate 17 2.

A sub rail 170 is arranged corresponding to each of the openings 2X. A total of four subrails 170 extend left and right in a straight line. The sub rail 170 has a length obtained by subtracting the distance between the pair of support brackets 17 1 from the width dimension of the sliding door 3, and is extended between the support brackets 17 1. Fixed. The sub rail 170 has a guide groove 170a (sub track) which opens to the lower surface as shown in FIG. Both sides of the guide groove 170a are vertical. A narrow space 170b is formed above the guide groove 170a. The guide groove 170a and the space 170Ob have the same shape as the guide groove 120f of the support fitting 120 of the sliding door 3 and the space 120g.

Next, the operation of the guide device of the seventh embodiment will be described. In a state in which a plurality of, for example, all four openings 2X are closed by the corresponding sliding doors 3, the front surfaces of the sliding doors 3 are flush as in the first embodiment.

When the sliding door 3 is in the closed position, the rotating rail 81 is in the horizontal inclined position, as shown in Fig. 21, and the lower roller 88 is folded down and accommodated in the accommodation groove 82 of the rotating rail 81. The sliding door 3 is supported so that its side surface contacts the first surface 82a (support surface), which supports the own weight of the sliding door 3. Due to the elastic force of the torsion panel 87, a turning torque is applied to the support bracket 86, and this turning torque acts to urge the sliding door 3 toward the closing position. Position is maintained.

When the sliding door 3 is in the closed position, the additional track 8 1 X of rotation rail 81 and the upright wall 81 y, the second piece 8 6 y and the third piece 8 6 _Z of the support bracket 8 6, other A space 180 in which the rollers 88 of the sliding door 3 can travel is formed. When all the sliding doors 3 are closed, the additional tracks 8 1 X of all the rotating rails 8 1 form a continuous track in a straight line.

At this time, the rotation rail 81 is rotated forward through the engagement between the roller 88 of the sliding door 3 and the accommodation groove 82 of the rotation rail 81, and is in the vertical upright position. At this time, the support bracket 86 rotates 90 ° against the torsion spring 86, so that the roller 88 is allowed to stand up from the fall state. With the rotation of the rotating rail 81, the additional track 81X of the rotating rail 81 deviates from the continuous track, and the auxiliary track 82b of the rotating rail 81 replaces the continuous track. Department. The roller 88 rides on the auxiliary track 82b such that its peripheral surface hits the catching track 82b of the rotating rail 81.

At a specific point in the process of the bow I door 3 moving from the closed position to the open preparation position, the torque due to the weight of the sliding door 3 exceeds the torque produced by the torsion panel 87, and the sliding door 3 can move to the open preparation position by its own weight. it can. As shown in FIG. 22, when the locking portion 81z of the rotating rail 81 hits the load receiving portion 80a of the support bracket 80, the sliding door 2 stops at the opening preparation position.

When the sliding door 3 moves from the closed position to the open preparation position while being supported by the rotating rail 81, the sliding door 3 is also displaced downward. Along with this, the support structure is

The projection 20 20 d moves obliquely forward along the inclined groove 17 2 b of the guide plate 17 2 and reaches the notch 17 2 c. In this way, the sliding door 3 can be moved to the preparation position by opening the upper edge in a stable manner. Sliding door 3 opens and reaches the preparatory position, and the support bracket 120 projections

When 120 d enters the notch 170 c, the roller 125 of the support bracket 120 is located at a position corresponding to the guide groove 170 a of the IJ Reynole 170. 6143

Next, open the bow door 3 and move it from the preparation position to the left or right opening position. At this time, the roller 88 of the support bracket 86 is separated from the auxiliary track 51 of the rotating rail 81, and the additional track of the rotating rail 81 corresponding to the adjacent sliding door 3 as shown in Fig. 23. Change to 8 1 X. As is evident from this, the additional track 8 1 X of the sliding door 3 in the closed state constitutes the main track for the sliding door 3 that opens, and only the rotating rail 8 1 of the sliding door 3 in the closed state is used. Constitutes the main rail. As shown in FIG. 23, the roller 88 of the sliding door 3 that opens is running in a space 180 formed by the support bracket 86 of the sliding door 3 in a closed state and the rotating rail 81. The catching roller 89 is guided by a regulating wall 81y and a locking portion 81z of the rotating rail 81.

When the sliding door 3 is opened, as shown in FIG. 28, the roller 1 25 of the sliding door 3 is formed by the guide groove 170 a of the sub rail 170 and the support bracket 120 of the sliding door 3 in the closed state. Pass through the guide groove 1 20 f. In addition, the upright portion 120 c of the support bracket 120 of the sliding door 3 that moves open passes through the notch 17 2 c of the guide plate 17 2, and passes through the space 170 b of the auxiliary rail 170. It passes through the space 120 g of the support bracket 120 of the sliding door 3 in the closed state.

As shown in FIGS. 23 and 28, the opened sliding door 3 overlaps the other closed sliding doors 3.

The rotating rail 81 left after the sliding door 3 has left at the open position is maintained in an upright state by the maintenance mechanism 83 as described above. When the sliding door 3 returns from the opening position to the opening preparation position, the positioning is performed by the positioning mechanism 84. More specifically, when the sliding door 3 is opened from the right, for example, and returns to the preparation position, the support shaft 88 X of the roller 88 is moved to the right side of the moving member 84 b of the positioning mechanism 8.4. In this case, the moving member 84b is tilted so that the right side is raised. When the sliding door 3 moves further, the roller 88 enters the engaging surface 84y of the moving member 84b, and opens the sliding door 3 to position it in the preparation position. Thereafter, by pushing the sliding door 3 backward, the support bracket 86 and the rotating rail 81 rotate 90 °, respectively, and return to the state of FIG. When returning the sliding door 3 to the closed position, it is necessary to lift the sliding door 3 lightly with the force of subtracting the elastic force of the torsion panel 87 from the own weight of the sliding door 3, but automatically from the middle with the force of the torsion panel 87. To the closed position.

Other operations are the same as those of the other embodiments described above. Next, an eighth embodiment of the present invention will be described with reference to FIGS. In this embodiment, the upper structure and the lower structure of the seventh embodiment are arranged upside down, and the corresponding components are denoted by the same reference numerals as in the seventh embodiment. Sliding door 3 moves upward in the process of moving from the closed position to the open preparation position. Accordingly, as shown in FIGS. 33 and 34, the inclined grooves 172b of the guide plates 172 are inclined upward as they move forward. The major difference from the seventh embodiment is as follows. As shown in FIG. 31, when the sliding door 3 is in the closed position, the side surface of the roller 88 in the falling state hits the fourth surface 82 d of the accommodation groove 82. That is, the fourth surface 8 2 d is provided as a support surface for supporting the sliding door 3. As shown in Fig. 32, when the sliding door 3 is opened and is in the preparation position, the upright roller 88 rides on the third surface 82c far from the rotation center in the accommodation groove 82 of the rotation rail 81. . That is, the third surface 82c is provided as an auxiliary orbit.

In the present embodiment, the third piece 86 z of the support bracket 86 of the sliding door 3 in the closed state is provided as an additional track for placing another sliding door 3 that opens.

In the eighth embodiment, an urging mechanism 200 shown in FIG. 35 is used instead of the torsion spring 87 of the seventh embodiment to maintain the closed position. The biasing mechanism 200 includes a pair of cylindrical cams 201, 202, a compression coil spring 203, a shaft 204, and a pair of brackets 205, 206. It has. One bracket 205 is fixed to the rear surface of the sliding door 3, and one cam 201 is fixed to the bracket 205. The other bracket 206 is fixed to a third piece 86 z of a support bracket 86 for supporting the roller 88. The right side of the shaft 204 is rotatably inserted and supported by the placket 205 and the cam 201. The left side peripheral surface of the shaft 204 has a key 204 a extending in the axial direction, and is inserted and supported by the placket 206 and the cam 202 so as not to rotate. The shaft 204 is arranged on the same straight line as the rotation axis 86 a of the support bracket 86. The coil spring 203 is interposed between the cam 202 and the bracket 206, and urges the cam 202 toward the cam 201. The opposing end surfaces of the cams 201 and 202 are cam surfaces 201a and 202a shown in FIG. 36, and are in contact with each other by the force of the coil spring 203. Cam 2 0 1 force T / JP2004 / 006143

26

The cam surface 2Ola has two peaks 201x, and the cam surface 202a of the cam 202 also has two peaks 202x.

In the state where the sliding door 3 is closed, as shown in FIG. 36 (A), the peak portion 202 of the cam 202 hits one inclined surface of the peak portion 210 of the cam 201. As a result, the force of the coil spring 203 is converted into the one-way rotational torque Fa by the cam 202. This rotational torque Fa acts as a force for urging the sliding door 3 backward. Thereby, the closed position of the sliding door 3 is stably maintained.

When the sliding door 3 is pulled out from the closed position to the open preparation position, the support bracket 86 rotates, and accordingly, the cam 202 rotates relatively to the cam 201 to a predetermined angle (for example, 2). 0 °) When rotated, the peak portion 202X crosses the peak portion 201X and hits the other inclined surface of the peak portion 210X. As a result, as shown in FIG. 36 (B), a rotation torque F opposite to that in the closed state acts. This rotational torque Fb acts as a force to move the sliding door 3 upward (to the opening preparation position) against its own weight. As a result, the sliding door 3 is stably maintained at the opening preparation position.

Next, a ninth embodiment of the present invention will be described with reference to FIGS. Since the present embodiment has a structure similar to that of the seventh embodiment shown in FIGS. 21 to 30, the corresponding components are denoted by the same reference numerals and detailed description thereof will be omitted. The parts are not shown. The major differences between the substructures are as follows. As shown in FIG. 37, when the sliding door 3 is in the closed position and the turning rail 81 is in the first turning position, the turning shaft 86 a of the support bracket 86 is moved to the position of the turning rail 81. It is located behind the rotating shaft 80b. Then, as shown in FIG. 38, the rotating shaft 8 6a of the support bracket 86 when the sliding door 3 is in the opening preparation position and the rotating rail 81 is in the second rotation position is the rotating rail 8 It is located forward of the first rotating shaft 80b. Therefore, as shown in FIG. 42, in the middle of the sliding door 3 from the closing position to the opening preparation position, the rotating shaft 86a is highest when it is directly above the rotating shaft 80b. Draw an arc. Accordingly, the vertical movement amount Δ Η of the rotation shaft 86 a is smaller than the horizontal movement amount AL of the rotation shaft 86 a from the first rotation position to the second rotation position of the rotation rail 81. , That is, the difference between the maximum height of the rotation shaft 86a and the height at the first rotation position can be small. The difference ΔΗ between the height of the rotating shaft 86a at the first rotating position and the second rotating position is smaller than ΔΗ '. Sliding door 3 lower edge Describes the same trajectory as the rotation axis 86a.

Other differences in the above substructure are as follows. A stopper 84 z is formed in the holder 84 a, and the stopper 84 a abuts the hanging piece 80 c of the support bracket 80, whereby the upright state of the rotating rail 81 is maintained. Two torsion springs 301 and 302 separated in the axial direction are wound on the rotating shaft 86a. The torsion panel 301 shown in Fig. 37 urges the support bracket 86 clockwise, and the torsion panel 302 shown in Fig. 38 urges the support bracket 86 counterclockwise. Thus, before the sliding door 3 is mounted on the main body 1, the roller 88 is maintained at the neutral position inclined with respect to the sliding door 3, facilitating the mounting operation.

Next, the upper structure will be described. As shown in FIG. 39 and FIG. 40, both ends of the auxiliary rail 400 are provided as guide members 401 and are fixed to the upper edge of the main body 1 via the holder 410. A small piece guide member 402 is fixed to the upper edge of the main body 1 at both ends by the holder 410. The guide member 402 is opposed to the guide member 401 in the left-right direction. The sub rail 400 and the guide member 402 are formed by extruded members having the same cross-sectional shape.

As shown in FIGS. 37 and 38, a guide groove 405 is formed by cutting off the intermediate wall portion 400 on the mutually facing surfaces of the guide members 401 and 402. The guide groove 405 has a horizontal portion 405 a and a vertical portion 405 b (rear end) at the rear end. The front end of the horizontal portion 405a is open through an opening 405c which is slightly downward. An arc-shaped concave portion 405d is formed on the upper surface near the rear end of the horizontal portion 405a.

On the other hand, a support bracket 420 is fixed to the upper edge of the sliding door 3. The support placket 4 20 has a horizontal portion 4 2 1 and an upright portion 4 ′ 2, and a cylindrical slider 4 2 5 (travel portion) is fixed to the upper end of the upright portion 4 2 2. Both ends of the slider 425 are provided as protrusions protruding left and right. When the sliding door 3 is located between the closing position and the opening preparation position, the horizontal portion 4 21 is located between the guide members 4 01 and 4 0 2, and the slider 4 25 is the guide groove 4 0 5 I'm getting into. The auxiliary bracket 429 and the slider 425 form an auxiliary traveling body 429. PT / JP2004 / 006143

The operation of the ninth embodiment will be described. When the sliding door 3 is in the closed position as shown in FIG. 37, the rotating rail 81 is in the down position, and the slider 425 is located at the lower end of the vertical portion 405b of the guide groove 405. . When the sliding door 3 is opened and pulled out to the ready position, the rotating rail 81 rotates and stands up, and the roller 88 also stands up. In this process, as described above, the rotation axis 86a of the support bracket 86 draws an arc trajectory with the highest height in the middle. At this time, the slider 4 25 rises along the vertical portion 4 05 b of the guide groove 4 0 5, moves forward along the horizontal portion 4 0 5 a, and further lowers slightly to open the opening 4 0 5. Reaches 5 c. As shown in FIG. 41, the horizontal movement amount of the slider 4 25 is equal to the horizontal movement amount AL of the rotation axis 86 a of the support bracket 86 in the lower structure, and the vertical movement amount is It is equal to the difference Δ の between the height of the rotating shaft 86 a at the moving position and the second rotating position. As described above, since the vertical movement amount Δ の of the slider 425 can be small, the guide members 401 and 402 can be reduced, and the size of the entire guide device can be reduced. '

As is clear from the above description, the movement trajectory of the rotation axis 86a of the support bracket 86, that is, the movement trajectory of the lower edge of the sliding door 3, is the movement trajectory of the slider 4 25, that is, the movement of the upper edge of the sliding door 3. Different from the trajectory. This difference in the movement locus is compensated for by a slight inclination of the sliding door 3. When the rotation axis 86a is near the vertex of the circular arc locus, the inclination of the sliding door 3 can be moderated by the slider 425 entering the recess 405d of the guide groove 405. it can.

As in the seventh embodiment, when the sliding door 3 moves from the opening preparation position to the opening position, it moves on the additional track 81X of the rotating rail 81 of the sliding door 3 at the other closed position. At this time, the slider 425 passes through the opening 405c of the auxiliary rail 400, that is, the auxiliary track. The opening 4 0 5 c is located above the support bracket 4 20 of the sliding door 3 in the closed position and is further away from the main unit 1 than the support bracket 4 20. 20 and the support bracket 420 in the closed position do not interfere.

The structures of the seventh to ninth embodiments may be used to open and close one sliding door. In this case, a rail member having a fixed track is used as the main track.

All of the embodiments described above can also be applied to devices that open and close openings such as houses, top bags, furniture, and large refrigerators. Openings corresponding to multiple sliding doors are separated from each other It may be. '

The opening position of the sliding door may be behind the closing position. In this case, the sliding door is pushed out to move from the closed position to the open preparation position.

The interrupted orbit may be in the form of an arc with a large curvature. In this case, the sliding door preferably has an arc of a cross section corresponding to the rail.

The main traveling body attached to the sliding door may use a slider instead of a roller. When the present invention is used to guide one sliding door for opening and closing a window, a structure may be employed in which the door is flush with the door pocket at the closed position and housed in the door pocket at the open position. INDUSTRIAL APPLICABILITY The present invention can be applied not only to sliding doors that open and close openings, but also to movement of panels (plate-like objects) supported on wall surfaces.

The features of the above-described embodiments can be appropriately combined. Industrial potential
