The rotating link 50 is urged rearward by the elastic force of the torsion spring 55, so that the rail portion 51 of the rotating link 50 is attached to the frame as shown in FIGS. 2 (A) and 7 (A). The first position above the upper frame portion 1c is maintained. Note that the rearward rotation of the rotation link 50 is prevented by a stopper (not shown) installed behind the rotation link 50 in the upper frame portion 1c. The rearward rotation of the rotation link 50 may be prevented by the sliding door 3 hitting the frame 1.
As shown in FIG. 1A, when all the sliding doors 3 are closed, the rail member 11 of the support bracket 10 is collinear with the fixed rail 39 fixed to the frame 1, and the plurality of rail members A continuous track M is formed in a straight line by the eleven additional tracks 11x and the fixed tracks 39x of the plurality of fixed rails 39. 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 protrusions 20d of the support bracket 20 are located in the vicinity of the upper ends of the inclined grooves 72b of the left and right guide plates 72 facing each other with the gap 71 therebetween, thereby preventing the lower edge of the sliding door 3 from swinging in the front-rear direction. . Further, the guide groove 20f of the rail portion 20e of the support fitting 20 is coincident with the notch 72a of the guide plate 72, and is continuous with the guide groove 70a of the sub rail 70 through the notch 72a.
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 FIG. 1 (B), FIG. 2 (B), FIG. 6 and FIG. 7 (B), the sliding door 3 is grasped by the handle 3a and pulled out to the front opening preparation position. At this time, the rotation link 50 is rotated forward against the torsion spring 55 through the engagement of the roller 15 of the sliding door 3 and the rail portion 51 of the rotation link 50. As a result, the rail member 11 of the sliding door 3 is detached from the fixed rail 39, and instead, the rail portion 51 of the rotation link 50 reaches the second position and is aligned with the fixed rail 39. As the rotation link 50 rotates from the first rotation position to the second rotation position, the upper surface portion of the rail portion 51 that supports the roller 15 changes from the support surface 51y to the auxiliary track 51x.
When one sliding door 3 is in the opening preparation position, the continuous track M that forms a straight line is a fixed track 39x of four fixed rails 39 and two rail portions 51 corresponding to the sliding door 3 in the opening preparation position. The auxiliary track 51x and the additional track 11x of the rail member 11 of the other three sliding doors 3 are constructed. In addition, further forward rotation of the rotation link 50 is prevented 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 while being supported by the rotation link 50 from the closed position to the opening preparation position, the sliding door 3 is also displaced downward. Accordingly, the support fitting 20 is guided by the guide surfaces 72x of the pair of guide plates 72, and the pair of left and right protrusions 20d of the support fitting 20 moves obliquely forward along the inclined grooves 72b of the left and right guide plates 72. The notch 72c is reached. In this way, the sliding door 3 can move to the preparation position where the lower edge portion is stably opened. When the sliding door 3 reaches the opening preparation position and the projection 29d of the support metal fitting 20 enters the notch 72c, the roller 25 of the support metal fitting 20 is in a position corresponding to the guide groove 72a of the guide plate 72, and the rail of the support metal fitting 20 The portion 20e is detached from the secondary rail 70.
Next, the sliding door 3 is moved from the opening preparation position to either the left or right opening position. At this time, the roller 15 of the support bracket 10 is separated from the auxiliary track 51 x of the rail portion 51 of the rotation link 50. When the sliding door 3 is moved to the right as shown in FIG. 1C, the roller 15 of the right upper metal fitting 15 moves to the additional track 11x of the rail member 11 in the support metal fitting 10 of the right adjacent sliding door 3. Furthermore, it moves to the fixed track 39x of the fixed rail 39. The roller 15 of the left support bracket 10 moves from the auxiliary track 51x of the rail portion 51 to the fixed track 39x of the fixed rail 39 on the right side. As is clear from this, the fixed track 39x and the additional track 11x of the closed sliding door 3 constitute the 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 this specification, the opening position of each sliding door 3 refers to an arbitrary position in a range from the position where the sliding door 3 partially opens the opening 2x to the position where it overlaps the other sliding doors 3 on the left and right ends. .
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 that is collinear with the fixed rail 39. More specifically, in the state where 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 rotation links 50, as shown in FIG. The front end edge of the slider 62 of the maintenance mechanism 60 provided on the left rotation link 50 is in contact with the engagement surface 10 a of the support fitting 10 and is in a position retracted against the compression coil spring 63. At this time, the follower pin 67 of the locking rod 61 is located at the intersection of the first portion 66 a and the second portion 66 b of the cam hole 66 of the slider 62, and the locking rod 61 is substantially flush with the end surface of the rail portion 51. It is in the retreat position that makes one.
Even if the sliding door 3 moves to the opening preparation position, the maintenance mechanism 60 is maintained in the above state. When the sliding door 3 moves to the left or right from the opening preparation position, as shown in FIG. 11B, the left or right edge of the engagement surface 10a of the support fitting 10 temporarily pushes the slider 62, and 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. 11C, the slider 62 is released from the pressed state by the engagement surface 10a of the support fitting 10 and protrudes forward. Accordingly, the follower pin 67 relatively moves along the second portion 66b from the first portion 66a of the cam hole 66 and reaches the rear end of the second portion 66b. In this process, the engagement rod 61 protrudes from the end surface of the rail portion 51 and fits into the locking recess 31 b formed on the end surface of the columnar portion 31 of the support fitting 30. As a result, the rail portion 51 of the left rotation link 50 is maintained coaxially 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 maintained coaxially with the fixed rail 39.
As a result, even if one sliding door 3 moves toward the open position, the auxiliary track 51x of the rotation link 50 corresponding to this sliding door 3 remains as a part of the continuous track M, and the sliding door 3 remains in the continuous track M. The sliding door 3 can be received at a portion where the roller 15 is on the continuous track M.
When the sliding door 3 moves from the opening preparation position to either the left or right opening position, the roller 25 of the lower support bracket 20 enters the guide groove 70a of the sub rail 70 through the notch 72a of the guide plate 72, and this guide groove Travel along 70a. In addition, when the sliding door 3 is in the opening preparation position and the opening position, the support bracket 20 releases the restraint 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 sub rail 70.
The sliding door 3 in the open position can be returned to the closed position by being moved rearward after being moved in the left-right direction and returned to the open preparation position. As described above, since the rail portion 51 of the rotation link 50 is locked coaxially with the fixed rail 39, the roller 15 of the sliding door 3 can be received when the sliding door 3 returns to the opening preparation position. When the sliding door 3 reaches the opening preparation position, the leading edge of the slider 62 of the maintenance mechanism 60 is pushed by the support fitting 10 to fit the engagement surface 10a, thereby positioning the sliding door 3 and the maintenance mechanism 60. The lock state of the rotation link 50 is released.
When three or more sliding doors 3 are installed as in the present embodiment, when one sliding door 3 is in the open position, the other sliding door 3 is similarly prepared from the closed position to the opening preparation position. It can be moved from the position to the open position. Therefore, the two sliding doors 3 can be replaced with the first position.
In the present embodiment, partitions of various lengths can be easily formed by aligning various components, that is, the support brackets 10 and 20, the rotation link 50, the support bracket 30, and the pipe 35 in units of the sliding door 3. Can do. Note that the short sub-rail 70 positioned at the left and right ends of the partition and the guide plate 72 fixed to the sub-rail 70 may be omitted. In this case, the sliding doors 3 at both ends are guided by the single guide plate 72 in the process of moving from the closed position to the opening preparation position.
Next, another embodiment of the present invention will be described. In these embodiments, components corresponding to the embodiments described earlier are assigned the same reference numerals, and detailed descriptions thereof are omitted.
In the second embodiment shown in FIG. 16, the fixed rail 39 is arranged not over the central portion of the upper edge of each opening 2x but over the adjacent opening 2x as in the first embodiment. The pair of support fittings 10 of each sliding door 3 is arranged away from the left and right ends of the sliding door 3 and closer to the center. The left and right pivot links having the same shape as in the first embodiment are also arranged at positions corresponding to the support fitting 10. A rail portion 51 ′ (corresponding to the rail portion 51 of the first embodiment) of the left and right pivot links and a pipe 151 connected between the rail portions 51 ′ form a long auxiliary track. Moreover, the rail member 11 ′ (corresponding to the rail member 11 of the first embodiment) of the left and right support fittings 10 and the pipe 111 connected between these rail members 11 ′ form a long additional track. Other configurations are the same as those of the first embodiment. In the second embodiment, there are fewer fixed rails 39 than in the first embodiment.
In the third embodiment shown in FIG. 17, the fixed rail 39 of the first and second embodiments is omitted. Instead, the auxiliary track made up of the rail portion 51 ′ and the pipe 151 and the additional track made up of the rail member 11 ′ and the pipe 111 have the same length as the width of the sliding door 3. In this embodiment, when one sliding door opens, a main track for the sliding door that opens is constructed only by the additional tracks of the remaining closed sliding doors.
The fourth embodiment shown in FIG. 18 is an opening / closing device provided with one sliding door applied to a house window, and the basic structure is similar to that of the first embodiment. Upper and lower frame portions 1c and 1d of the frame 1 surrounding the opening 2x serving as a window extend from the opening 2x to the left or right. A fixed rail 39 is installed just above the opening 2x of the upper frame portion 1c, as in the first embodiment, and a pair of rotating links are installed adjacent to the left and right ends thereof. Further, another fixed rail 39 is installed in a portion extending from the opening 2x in the upper frame portion 1c.
On the other hand, a sub rail 70 extending from the middle of the opening 2x to the middle of the extension is fixed to the lower frame portion 1d. Guide plates 72 are fixed to both ends of the sub rail 70. Although the sliding door 3 and the components attached to this sliding door 3 are the same as that of 1st Embodiment, there is no additional track | orbit. Also in this embodiment, the sliding door 3 moves in the front-rear direction at the closed position and the opening preparation position. This opening / closing device can be used, for example, when the airtightness of the house is increased by the close contact of the sliding door 3 to the frame 1. Further, the present invention can also be applied to an opening / closing device in which the sliding door is accommodated in the door pocket at the open position and the sliding door is flush with the door pocket in the closed state.

The metal fitting 20, the auxiliary rail 70, etc. can also be omitted.
In 6th Embodiment shown in FIG. 20, the arrangement | positioning of the component which supports the metal fittings 10 and 20 and the sliding door 3 with which the sliding door 3 is mounted | worn is upside down with 1st Embodiment. In this embodiment, the load of the sliding door 3 is received by the roller 16 of the support fitting 10 fixed to the lower edge portion of the sliding door 3 riding on the rail portion 51 and the fixed rail 39 of the rotation link 50. In this case, the roller 16 has a fitting groove that fits with the rail portion 51 on its peripheral surface. The sliding door 3 moves upward in the process from the closed position to the opening preparation position. Since other configurations and operations are the same as those of the first embodiment, the description thereof is omitted.

The rotating rail 81 has a wide and narrow plate shape and has two parallel flat surfaces 81a and 81b. The length of the rotating rail 81 is substantially the same as the width of the opening 2x, that is, the width of the sliding door 3. equal. The rotation rail 81 can be rotated in an angle range of approximately 90 ° between a rearward horizontal fall position (first rotation position) and a front standing position (second rotation position). The horizontal fall position of the rotating rail 81 is maintained by the rotating rail 81 hitting the upper surface of the load receiving portion 80a of the support fitting 80.
On the other surface 81b of the rotating rail 81, a receiving groove 82 is formed at the center in the width direction. The housing groove 82 is open at the horizontal fall position, and a pair of protrusions 82x facing each other is formed at the opening edge. The accommodation groove 82 has a wide bottom surface 82a, narrow second and second surfaces 82b and 82c on both sides thereof, and a fourth surface 82d inside the protrusion 82x. In this embodiment, the 1st surface 82a is provided as a support surface, and the 2nd surface 82b near a rotation center is provided as an auxiliary track. Moreover, the surface part close | similar to the rotating shaft 80b among the flat surfaces 81b of the rotating rail 81 is provided as the addition track | orbit 81x.
At the end of the rotating rail 81 on the rotating shaft 80b side, there are a restriction wall 81y protruding from the additional track 81x, and a locking portion 81z protruding perpendicularly to the restriction wall 81y and opposite to the additional track 81x. And are formed. As shown in FIG. 22, when the rotating rail 81 is in the upright position, the engaging portion 81z hits the front edge of the load receiving portion 81a, so that the rotating rail 81 is prevented from falling forward.
When the rotating rail 81 is in the standing position, the backward tilting is prevented by the maintenance mechanism 83 shown in FIG. The maintenance mechanism 83 is provided in the vicinity of the free end of the rotation rail 81 on one end side in the longitudinal direction of the rotation rail 81. The maintenance mechanism 83 includes a holder case 83a fitted to one end of the rotating rail 81, a ball 83b disposed at the open end of the holder case 83a, and the ball 83b accommodated in the holder case 83a on the side wall of the support fitting 80. It has a coil spring 83c that pushes inward, and a concave portion 83d that is formed on the side wall of the support fitting 80 and forms a spherical surface. When the rotating rail 81 is in the standing position, the ball 83b fits into the recess 83d and holds the rotating rail 81 in the standing position.
The rotating rail 81 is further provided with a positioning mechanism 84 shown in FIGS. The positioning mechanism 84 performs positioning when the sliding door 3 returns from the opening position to the opening preparation position, and includes a holder 84a having an L-shaped cross section and a moving member 84b. The first piece of the holder 84a is fixed to the free end of the rotating rail 81 by a fixture 84e, and the moving member 84b is disposed between the second piece of the holder 84a and the flat surface 81b of the rotating member 81. Yes. A pair of left and right pins 84c are fixed to the second piece of the holder 84a.
The moving member 84b has a pair of elongated holes 84h on the left and right. Each elongated hole 84h has an arc shape and draws an arc centered on the end of the other elongated hole 84h (the upper end in the standing state of the rotating rail 81 as shown in FIG. 22). The pin 84c is inserted into the elongated hole 84h. Thereby, the moving member 84b can swing and move up and down. The moving member 84b has a hole in the surface facing the first piece of the holder 84a, and the coil spring 84d is accommodated in the hole. The moving member 84b is urged by the coil spring 84d in a direction away from the first piece of the holder 84a. The moving member 84b has left and right inclined guide surfaces 84x and a central arc-shaped engagement surface 84y on the surface of the holder 84a opposite to the first piece. The operation of the positioning mechanism 84 will be described later.
On the other hand, a pair of support fittings 85 are fixed to the left and right ends on the rear surface of the lower end of the sliding door 3. An auxiliary roller 89 is rotatably supported at the rear ends of the support fittings 85. Between the pair of support fittings 85, a support bracket 86 (running body support bracket) made of an elongated extruded material having a substantially Z-shaped cross section is connected with its base end portion being rotatable via a rotation shaft 86a. . The rotation axis of the support bracket 86 is parallel to the rotation axis of the rotation rail 81 and extends horizontally from side to side. The support bracket 86 includes a first piece 86x on the distal end side that is perpendicular to each other, a second piece 86y in the middle, and a third piece 86z on the proximal end side that is parallel to the first piece 86x, and a torsion spring 87. The biasing member is biased counterclockwise by the biasing member. The torsion spring 87 is wound around the rotation shaft 86 a, one end is hooked on the pin 87 a fixed to the support fitting 85, and the other end is hooked on the second piece 86 y of the support bracket 86.
A disk-shaped roller 88 (running body) is rotatably supported on the first piece 86x of the support bracket 86 via a support shaft 88x orthogonal to the first piece 86x. The roller 88 is received in the receiving groove 82 of the rotating rail 81.
Next, the upper structure of the seventh embodiment will be described with reference to FIGS. This upper structure is similar to the lower structure of the first embodiment and the upper structure of the sixth embodiment, and will be described briefly. A support fitting 120 (running unit support bracket) is fixed to the rear surface of the upper edge of the sliding door 3, for example, at the right end. The support bracket 120 includes a vertical fixing portion 120a that is fixed to the rear surface of the sliding door 3 and protrudes upward, a horizontal portion 120b that protrudes horizontally from the upper end of the fixing portion 120a, and a rear end of the horizontal portion 120b. And a pair of protrusions 120d projecting left and right from the upper end of the standing part 120c. A rail portion 120e, which is a part of the support fitting 120, is fixed to the front surface of the fixing portion 120a of the support fitting 120, and a guide groove 120f is formed in the rail portion 120e. A narrow space 120g is formed above the guide groove 120f.
A roller 125 (running portion) having a vertical rotation shaft is rotatably attached to the upper surface of the horizontal portion 120b of the support fitting 120. The support bracket 120 and the roller 125 constitute the auxiliary traveling body 129.
On the upper surface of the upper frame portion 1c of the frame 1, a pair of support fittings 171 are fixed to the respective openings 2x at the right end portion. Guide plates 172 (guide members) are respectively fixed to the opposing surfaces of the support fittings 171. As best shown in FIG. 27, on the opposing surface (guide surface) of this guide plate 172, a linear inclined groove 172b (guide groove) is formed that proceeds downward as it goes forward. 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. The notch 172c is formed at the lower edge of the guide plate 172.
Sub rails 170 are arranged corresponding to the openings 2x. A total of four sub rails 170 extend in a straight line from side to side. The sub rail 170 has a length obtained by subtracting the distance between the pair of support brackets 171 from the width dimension of the sliding door 3, and is fixed so as to be spanned between the support brackets 171. As shown in FIG. 28, the sub rail 170 has a guide groove 170a (sub track) that opens on the lower surface. Both side surfaces 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 170b have the same shape as the guide groove 120f and the space 120g of the support fitting 120 of the sliding door 3.
Next, the operation of the guide device of the seventh embodiment will be described. In a state where all of a plurality of, for example, four openings 2x are closed by the corresponding sliding door 3, the front surface of the sliding door 3 is flush with the same as in the first embodiment.
When the sliding door 3 is in the closed position, as shown in FIG. 21, the rotation rail 81 is in the horizontal fall position, the lower roller 88 is fallen and is accommodated in the accommodation groove 82 of the rotation rail 81, and its side surface is It rides on the first surface 82a (support surface), thereby supporting the weight of the sliding door 3. A rotational torque is applied to the support bracket 86 by the elastic force of the torsion spring 87, and this rotational torque acts to urge the sliding door 3 toward the closed position, so that the closed position of the sliding door 3 is maintained. ing.
When the sliding door 3 is in the closed position, a space in which the rollers 88 of the other sliding doors 3 can travel by the additional track 81x and the upright wall 81y of the rotating rail 81 and the second piece 86y and the third piece 86z of the support bracket 86. 180 is formed.
In a state in which all the sliding doors 3 are closed, a continuous track in which the additional tracks 81x of all the rotating rails 81 form a straight line is constructed.
On the other hand, when the sliding door 3 is in the closed position, as shown in FIGS. 26 and 29, the support fitting 120 provided at the right end of the upper edge of the sliding door 3 is accommodated between the pair of guide plates 172. . The left and right protrusions 120d of the support fitting 120 are positioned in the vertical groove 172a of the pair of guide plates 172, and are prohibited from moving in the front-rear direction. In addition, the guide groove 120f of the support fitting 120 is continuous with the guide groove 170a of the sub rail 170 through a slight gap.
Next, the opening operation of one selected sliding door 3 will be described. Grab the handle 3 and pull the sliding door 3 to the front opening preparation position. At this time, the rotation rail 81 is rotated forward through the engagement of the roller 88 of the sliding door 3 and the accommodation groove 82 of the rotation rail 81, and becomes a vertical standing position. At this time, the support bracket 86 is rotated 90 ° against the torsion spring 86, so that the roller 88 is allowed to stand up from the collapsed state. With the rotation of the rotation rail 81, the additional track 81x of the rotation rail 81 deviates from the continuous track, and instead, the auxiliary track 82b of the rotation rail 81 becomes a part of the continuous track. Further, the roller 88 rides on the auxiliary track 82 b so that the peripheral surface thereof contacts the auxiliary track 82 b of the rotating rail 81.
At a specific point in the process of the sliding door 3 from the closed position to the opening preparation position, the torque due to the weight of the sliding door 3 exceeds the torque by the torsion spring 87, and the sliding door 3 can move to its opening preparation position by its own weight. As shown in FIG. 22, the sliding door 2 stops at the opening preparation position when the locking portion 81 z of the rotating rail 81 hits the load receiving portion 80 a of the support fitting 80.
When the sliding door 3 moves while being supported by the rotating rail 81 from the closed position to the opening preparation position, the sliding door 3 is also displaced downward. Accordingly, in the upper structure of the guide device, the protrusion 120d of the support fitting 120 moves obliquely forward along the inclined groove 172b of the guide plate 172 and reaches the notch 172c. In this way, the sliding door 3 can move to the opening preparation position with the upper edge portion also being stable. When the sliding door 3 reaches the opening preparation position and the protrusion 120d of the support bracket 120 enters the notch 172c, the roller 125 of the support bracket 120 is at a position corresponding to the guide groove 170a of the sub rail 170.
Next, the sliding door 3 is moved from the opening preparation position to either the left or right opening position. At this time, the roller 88 of the support metal fitting 86 moves away from the auxiliary track 51x of the rotation rail 81, and changes to the additional track 81x of the rotation rail 81 corresponding to the adjacent sliding door 3 as shown in FIG. As is clear from this, the additional track 81x of the closed sliding door 3 forms a main track for the sliding door 3 that opens, and the main rail is configured only by the pivoting rail 81 of the closed sliding door 3. Is done. As shown in FIG. 23, the roller 88 of the sliding door 3 that performs the opening operation travels in a space 180 that is configured by the support bracket 86 and the rotating rail 81 of the sliding door 3 in the closed state. The auxiliary roller 89 is guided by the restriction wall 81y and the locking portion 81z of the rotating rail 81.
When the sliding door 3 opens, the roller 125 of the sliding door 3 passes through the guide groove 170a of the sub rail 170 and the guide groove 120f of the support fitting 120 of the closed sliding door 3 as shown in FIG. Further, the upright portion 120c of the support metal 120 of the sliding door 3 that opens is passed through the notch 172c of the guide plate 172, and passes through the space 170b of the sub rail 170 and the space 120g of the support metal 120 of the closed sliding door 3.
As shown in FIG. 23 and FIG. 28, the opened sliding door 3 overlaps with the other closed sliding doors 3.
The rotating rail 81 left after the sliding door 3 leaves the open position is maintained in the standing state by the maintenance mechanism 83 as described above. When the sliding door 3 returns from the opening position to the opening preparation position again, positioning is performed by the positioning mechanism 84. More specifically, when the sliding door 3 opens from the right and returns to the preparation position, for example, the support shaft 88x of the roller 88 hits the inclined guide surface 84x on the right side of the moving member 84b of the positioning mechanism 84, and the moving member 84b Tilt it up. When the sliding door 3 further moves, the roller 88 enters the locking surface 84y of the moving member 84b, and opens the sliding door 3 and positions it at the preparation position. Thereafter, by pushing the sliding door 3 backward, the support bracket 86 and the rotating rail 81 are each rotated by 90 °, and return to the state of FIG. When the sliding door 3 is returned to the closed position, it is necessary to lift the sliding door 3 lightly with a force obtained by subtracting the elastic force of the torsion spring 87 from the dead weight of the sliding door 3. Reach 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. Corresponding components are assigned the same numbers as in the seventh embodiment in the figure. The sliding door 3 moves upward in the process of moving from the closed position to the opening preparation position. Accordingly, as shown in FIGS. 33 and 34, the inclined groove 172b of the guide plate 172 is inclined so as to go upward as it advances forward. The major differences from the seventh embodiment are 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 collapsed state hits the fourth surface 82 d of the accommodation groove 82. That is, the fourth surface 82 d is provided as a support surface that supports the sliding door 3. As shown in FIG. 32, when the sliding door 3 is in the opening preparation position, the standing roller 88 gets on the third surface 82 c 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 track.
Moreover, in this embodiment, the 3rd piece 86z of the support bracket 86 of the sliding door 3 of a closed state is provided as an additional track | orbit for mounting the other sliding door 3 which opens.
In the eighth embodiment, an urging mechanism 200 shown in FIG. 35 is used in place of the torsion spring 87 of the seventh embodiment in order to maintain the closed position. The urging mechanism 200 includes a pair of cylindrical cams 201 and 202, a compression coil spring 203, a shaft 204, and a pair of brackets 205 and 206. 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 the third piece 86z of the support bracket 86 for supporting the roller 88. The right side portion of the shaft 204 is rotatably inserted and supported by the bracket 205 and the cam 201. A key 204 a extending in the axial direction is provided on the peripheral surface of the left side portion of the shaft 204, and is inserted and supported by the bracket 206 and the cam 202 so as not to rotate. The shaft 204 is arranged on the same straight line as the rotation shaft 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 opposite end surfaces of the cams 201 and 202 are cam surfaces 201 a and 202 a shown in FIG. 36, and are in contact with each other by the force of the coil spring 203. The cam surface 201a of the cam 201 has two peak portions 201x, and the cam surface 202a of the cam 202 also has two peak portions 202x.
In the state where the sliding door 3 is closed, as shown in FIG. 36A, the peak portion 202x of the cam 202 hits one inclined surface of the peak portion 201x of the cam 201, whereby the force of the coil spring 203 is applied to the cam 202. It is converted into a unidirectional rotational torque Fa. 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 opening preparation position, the support bracket 86 is rotated, and accordingly, the cam 202 is rotated relative to the cam 201 and is rotated by a predetermined angle (for example, 20 °). The peak part 202x exceeds the peak part 201x and hits the other inclined surface of the peak part 201x. As a result, as shown in FIG. 36 (B), a rotational torque Fb opposite to that in the closed state acts. This rotational torque Fb acts as a force that moves 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 this embodiment has a structure similar to that of the seventh embodiment shown in FIGS. 21 to 30, corresponding components are denoted by the same reference numerals and detailed description thereof is omitted, and a part of the common structure is illustrated. Is omitted. The major differences in the substructure are as follows. As shown in FIG. 37, when the sliding door 3 is in the closed position and the rotation rail 81 is in the first rotation position, the rotation shaft 86a of the support bracket 86 is behind the rotation shaft 80b of the rotation rail 81. positioned. As shown in FIG. 38, the pivot shaft 86a of the support bracket 86 when the sliding door 3 is in the opening preparation position and the pivot rail 81 is in the second pivot position is more than the pivot shaft 80b of the pivot rail 81. Located in front. Therefore, as shown in FIG. 42, in the middle of the sliding door 3 from the closed position to the opening preparation position, the rotation shaft 86a draws an arc that is highest when it is directly above the rotation shaft 80b. Accordingly, the vertical movement amount ΔH ′ of the rotation shaft 86a, that is, the rotation shaft, compared to the horizontal movement amount ΔL of the rotation shaft 86a from the first rotation position to the second rotation position of the rotation rail 81. The difference between the maximum height of 86a and the height at the first rotation position may be small. The difference ΔH in the height of the rotation shaft 86a between the first rotation position and the second rotation position is smaller than ΔH ′. The lower edge of the sliding door 3 draws the same locus as the rotation shaft 86a.
Other differences in the substructure are as follows. A stopper 84z is formed on the holder 84a, and the stopper 84a abuts on the hanging piece 80c of the support fitting 80, so that the rotating rail 81 is kept upright. Two torsion springs 301 and 302 separated in the axial direction are wound around the rotation shaft 86a. The torsion spring 301 shown in FIG. 37 urges the support bracket 86 in the clockwise direction, and the torsion spring 302 shown in FIG. 38 urges the support bracket 86 in the counterclockwise direction, thereby attaching the sliding door 3 to the main body 1. Before the operation, the roller 88 is maintained in a neutral position inclined with respect to the sliding door 3 to facilitate the mounting operation.
Next, the upper structure will be described. As shown in FIGS. 39 and 40, both end portions of the sub rail 400 are provided as guide members 401 and are fixed to the upper edge portion 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 by the holder 410 at both ends thereof. 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 of an extruded die having the same cross-sectional shape.
As shown in FIGS. 37 and 38, the guide wall 401 and 402 are opposed to each other, and an intermediate wall 403 is cut off to form a guide groove 405. The guide groove 405 has a horizontal portion 405a and a vertical portion 405b (back end portion) at the rear end thereof. The front end of the horizontal portion 405a is opened through an opening 405c that extends slightly downward. An arcuate recess 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 bracket 420 has a horizontal portion 421 and an upright portion 422. A cylindrical slider 425 (running portion) is fixed to the upper end of the upright portion 422, and both end portions of the slider 425 are laterally extended. Provided as protruding protrusions. When the sliding door 3 is between the closed position and the opening preparation position, the horizontal portion 421 is positioned between the guide members 401 and 402, and the slider 425 enters the guide groove 405. These support brackets 420 and sliders 425 constitute a secondary traveling body 429.
The operation of the ninth embodiment will be described. As shown in FIG. 37, when the sliding door 3 is in the closed position, the rotating rail 81 is tilted and the slider 425 is positioned 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 preparation position, the turning rail 81 turns and rises, and the roller 88 also stands. In this process, as described above, the rotation shaft 86a of the support bracket 86 draws an arc locus whose maximum height is midway. At this time, the slider 425 rises along the vertical portion 405b of the guide groove 405, further moves forward along the horizontal portion 405a, and further falls slightly to reach the opening 405c. As shown in FIG. 41, the horizontal movement amount of the slider 425 is equal to the horizontal movement amount ΔL of the rotation shaft 86a of the support bracket 86 in the lower structure, and the vertical movement amount is the first rotation position and the second rotation position. Is equal to the height difference ΔH of the pivot shaft 86a. Thus, since the vertical movement amount ΔH of the slider 425 only needs to be small, the guide members 401 and 402 can be lowered, and the entire guide device can be downsized.
As is clear from the above description, the movement locus of the pivot shaft 86a of the support bracket 86, that is, the movement locus of the lower edge portion of the sliding door 3, is different from the movement locus of the slider 425, that is, the movement locus of the upper edge portion of the sliding door 3. This difference in the movement trajectory is compensated by a slight inclination of the sliding door 3. When the rotation shaft 86a is in the vicinity of the top of the arc locus, the slider 425 enters the recess 405d of the guide groove 405, so that the inclination of the sliding door 3 can be reduced.
Similar to the seventh embodiment, when the sliding door 3 moves from the opening preparation position to the opening position, the sliding door 3 gets on the additional track 81x of the turning rail 81 of the sliding door 3 in the other closed position. At this time, the slider 425 passes through the opening 405c of the secondary rail 400, that is, the secondary track. Since the opening 405c is above the support bracket 420 of the sliding door 3 in the closed position and is farther from the main body 1 than the support bracket 420, the support bracket 420 of the sliding door during the opening operation and the support bracket 420 in the closed position are Does not interfere.
You may use the structure of the said 7th-9th embodiment in order to open and close one sliding door. In this case, a rail member having a fixed track as the main track is used.
All the embodiments described above can also be applied to devices that open and close openings such as houses, roofing bags, furniture, and large refrigerators. The openings corresponding to the plurality of sliding doors may be partitioned from each other.
The sliding door opening preparation position may be behind the closing position. In this case, the sliding door is pushed to change from the closed position to the opening preparation position.
The continuous trajectory may form an arc with a large curvature. In this case, the sliding door preferably has a circular 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 a single sliding door for opening and closing a window, it can be structured to be flush with the door pocket at the closed position and accommodated in the door pocket at the open position.
The present invention can be applied not only to sliding doors that open and close an opening, but also to movement of a panel (plate-like object) supported by a wall surface.
The features of the embodiments described above can be combined as appropriate.
