Description

  The present invention relates to a sliding door device, and more particularly to a sliding door device in which the sliding doors are flush with each other in a closed state.

  Conventionally, in the case of three sliding doors, there is known a sliding type sliding door device in which each sliding door moves straight in parallel to be in a closed state, a right open state, or a left open state (see, for example, Patent Document 1). ).

  However, in the conventional example shown in Patent Document 1, each sliding door has a stepped shape from the front side to the rear side in the closed state, so that not only the appearance looks bad, but also the longitudinal direction of the upper rail for each sliding door. There is also a restriction that the degree of freedom in construction is small, such as the need to provide three rail portions in parallel in the front-rear direction orthogonal to each other, and thus the need to increase the overall expected dimension (depth) of the upper rail.

  In addition, a child sliding door is movably attached in the opening / closing direction on the surface side of the main sliding door, another child sliding door is movably attached in the opening / closing direction on the back side of the parent sliding door, and one child sliding door is on the surface side of the parent sliding door, Patent Document 2 discloses a sliding door device that can be greatly opened when the other child sliding door is opened by overlapping the back side of the parent sliding door.

  In the conventional example shown in this Patent Document 2, it is possible to reduce the number of rails, but it is necessary to provide the main sliding door with a guide groove and a slider for guiding the child sliding door so that they can run freely. Then, the guide groove is exposed and the appearance is deteriorated.

  In addition, in the fully closed state, two child sliding doors are pulled out on both sides of the main sliding door so that there is no step in the closed state, but it cannot be confirmed whether it is in the fully closed state. There is no mechanism to maintain a state where no step is generated in the closed state. Therefore, when the external force is inadvertently applied to the child sliding door in the closed state, the child sliding door moves so as to overlap the front side or the back side of the main door. There was a problem that.

  In addition, the sliding door is provided with a stopper for temporarily fixing the sliding door when the sliding door is closed to prevent a phenomenon that the sliding door rebounds and opens a gap when the sliding door is closed to maintain a sealed state in the closed state. This is known, for example, from Patent Document 3.

However, what is shown in this Patent Document 3 is a sliding sliding door, which is only a stopper for preventing the sliding door from rebounding when the sliding door is closed vigorously, with three sliding doors closed. No technology is disclosed for maintaining a state in which the three sliding doors are continuously arranged in a line.

It is possible to reliably prevent the phenomenon of being generated, and to maintain a state of being aligned in a flush manner, so that the sliding doors can be opened smoothly without colliding even when opening.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The sliding door device of the present invention has three sliding doors 1 as shown in FIGS. 1 and 2, and a central sliding door 1c in a closed state and a one sliding door 1a arranged on one side of the central sliding door 1c. And the other sliding door 1b disposed on the other side of the central sliding door 1c so that not only the three sliding doors 1 are arranged in a row in the closed state but also the entire three sliding doors are flush with each other. It is arranged. Thus, for example, when used as a closet door, the three sliding doors 1 can exhibit an appearance as a series of walls that are flush with each other without a step, and the appearance is good.

  When the three sliding doors 1 are moved from one sliding door 1a side to the other sliding door 1b side and opened as shown in FIG. 1, the one sliding door 1a guides to the front A of the other sliding door 1b and the central sliding door 1c. Is guided to the rear B of the other sliding door 1b, and the interlocking mechanism 15 is used to transmit the operating force on the one sliding door 1a side to the central sliding door 1c to open and close the central sliding door 1c following the one sliding door 1a. And.

  First, the guiding mechanism 19 guides the upper runners 21 to 23 attached to the upper part of the sliding door 1, the lower rollers 27 respectively attached to the lower part of the sliding door 1, and the upper runners 21 to 23 and the lower roller 27 to freely travel. The upper and lower rails 5 and 6 provided on the door frame 4 are configured.

  The door frame 4 is a rectangular frame that is attached to an opening for attaching the three sliding doors 1 so as to be freely opened and closed, and includes the upper and lower rails 5 and 6 and the left and right vertical frames 4a.

  The runners 21 to 23 are respectively attached to both left and right end portions of the upper end of the rear surface of the sliding door 1 via inverted L-shaped metal fittings 28, and the runners 21 to 23 are located behind the upper end of the sliding door 1. When the runners 21 to 23 are movably attached to the upper rail 5 described later, the sliding door 1 is suspended from the traveling support portion of the upper rail 5 by the runners 21 to 23. Become.

  As shown in FIGS. 3 and 4, the upper rail 5 includes an upper rail body 50 fixed to the housing, and an upper rail cover 51 (in the embodiment, the upper rail cover 51 is divided into a plurality of parts in the longitudinal direction). The upper rail body 50 and the upper rail cover 51 are screwed to each other.

  As shown in FIGS. 3 and 4, the upper rail 5 configured by attaching the upper rail cover 51 to the upper rail body 50 is aligned with the longitudinal directions A and B perpendicular to the longitudinal direction M of the upper rail 5. A common rail portion 7 and a groove-like central sliding door rail portion 8 are provided side by side. The common rail section 7 is capable of traveling on two left and right upper runners 21 and 22 provided at two ends of each upper end of one and the other sliding doors 1a and 1b (that is, the right sliding door 1a and the left sliding door 1b). The center sliding door rail portion 8 guides the left and right upper runners 23 provided at the upper end portion of the central sliding door 1c so as to run freely.

  The common rail portion 7 is formed in a substantially L shape from the both ends in the longitudinal direction M of the front rectilinear rail portion 9 to the rear B, extending in parallel with the longitudinal direction M of the upper rail 5. Bends from two bent left and right outer curved rail portions 11 and two positions closer to the inside than both ends in the longitudinal direction M of the front straight rail portion 9, and bends in a substantially L shape toward the rear B The left and right inner curved rail portions 12 are provided. By guiding the three sliding doors 1 with these two rail portions (common rail portion 7 and central sliding door rail portion 8), it is possible to reduce the expected size F (FIG. 4) of the entire upper rail 5. For example, when used as a closet door, the amount of storage can be increased, and even if load collapse occurs in the closet, for example, the one sliding door 1a is moved from the closed state to the other sliding door 1b side. Thus, it is possible to move forward along the outer curved rail portion 11 and the inner curved rail portion 12 and move along the front linear rail portion 9 in the opening direction (the other sliding door 1b side) to open.

  Further, the central sliding door rail portion 8 has a rearward straight rail portion 10 parallel to the front straight rail portion 9 and a position facing the left and right inner curved rail portions 12 in the rear straight rail portion 10. Each has two left and right curved rail portions 13 that are curved in a semicircular shape toward the front A from two locations that approach each other. 1, 3, and 4, 10 a and 10 b are branched from a communication portion between a longitudinal intermediate portion of the rear straight rail portion 10 and the left and right curved rail portions 13, and are intermediate between the rear straight rail portions 10. A straight running portion that continuously extends from the portion toward the left and right side portions of the rear straight running rail portion 1, and the upper runner 23 on the right side of the central sliding door 1c when the central sliding door 1c is brought to the left end of the straight running portion 10a. 10b is a part into which the upper runner 23 on the left side of the central sliding door 1c enters when the central sliding door 1c is brought to the right end.

  Rear left and right outer curved rail portions 11 provided on the common rail portion 7, rear left and right inner curved rail portions 12, rear left and right central sliding door rail portions 8 The front end portion of the curved rail portion 13 is located on a virtual straight line parallel to the front straight rail portion 9 and the rear straight rail portion 10. The distance between the rear end portion of the left outer curved rail portion 11 and the rear end portion of the left inner curved rail portion 12 is between the left and right upper runners 22 of the left sliding door 1 (that is, the other sliding door 1b). The distance between the rear end portion of the right outer curved rail portion 11 and the rear end portion of the right inner curved rail portion 12 is the right and left of the right sliding door 1 (that is, the one sliding door 1a). Further, the distance between the front end portions of the left and right curved rail portions 13 is set equal to the distance between the left and right upper runners 23 of the central sliding door 1c.

  Here, in the closed state, each upper runner 22 of the other sliding door 1b shown in FIG. 1A enters the respective rear end portions of the outer curved rail portion 11 and the inner curved rail portion 12 located on the left side, and the center. Each of the upper runners 23 of the sliding door 1c enters the respective front end portions of the two left and right curved rail portions 13, and each of the upper runners 21 of the one sliding door 1a is located on the right side. 12 are juxtaposed so that the sliding doors 1 are in the same plane parallel to the longitudinal direction M of the upper rail 5 (that is, the three sliding doors 1 are flush with each other). Is done.

  On the other hand, in the right-open state of FIG. 6, as shown in FIG. 1 (e), the upper runners 22 of the other sliding door 1b are located at the rear end portions of the outer curved rail portion 11 and the inner curved rail portion 12 positioned on the left side. The upper runner 23 on the left side of the central sliding door 1c moves to the left end of the rear straight rail section 10, the upper runner 23 on the right moves to the straight section 10a, and the upper runner of the one sliding door 1a. As 21 moves to the left side of the front-side straight-traveling rail portion 9, the first sliding door 1a, the other sliding door 1b, and the central sliding door 1c are stacked and juxtaposed in order from the front.

  Further, in the left open state of FIG. 7, each upper runner 21 of the one-side sliding door 1 a enters the respective rear end portions of the outer curved rail portion 11 and the inner curved rail portion 12 positioned on the right side, and the right side of the central sliding door 1 c. The upper runner 23 moves to the right end of the rear straight rail portion 10 and the left upper runner 23 moves to the straight portion 1b, and each upper runner 22 of the other sliding door 1b moves to the front straight rail portion 9. By moving to the left side, the other sliding door 1b, the one sliding door 1a, and the central sliding door 1c are juxtaposed in order from the front.

  These right open state and left open state can be arbitrarily selected. That is, the guiding mechanism 19 moves the central sliding door 1c to a position that does not overlap the other sliding door 1b in a state where the one sliding door 1a, the central sliding door 1c, and the other sliding door 1b overlap each other, and is flush with the other sliding door 1b. In addition, the sliding door 1a is moved to a position where it does not overlap with the other sliding door 1b and the central sliding door 1c so as to be guided to be flush with the central sliding door 1c.

  A pair of gap concealing L-shaped members facing each other may be attached to the mutual abutting portions of the sliding doors 1, but for example, as shown in FIG. It is also possible to provide 17 so as to eliminate the gap between the sliding doors 1.

  On the other hand, upper runners 21 (or upper runners 22 or upper runners 23) are provided on the left and right sides of the upper surface of each sliding door 1, respectively. As shown in FIG. 8, the upper runners 21 to 23 include a roller block 24 having a pair of upper rollers 26 and two auxiliary rollers 25 a (or auxiliary rollers 25 b) protruding upward from the upper surface of the roller block 24. It consists of and. The auxiliary roller 25a (or the auxiliary roller 25b) is guided by the branching member 18 shown in FIG.

  Here, as shown in FIG. 4B, the height is at a position shifted to the rear side of the upper surface of the upper runner 21 (or the upper runner 22) provided at each right end of the one sliding door 1a and the other sliding door 1b. Two auxiliary rollers 25a having a low height project upward, and the front of the upper surface of the upper runner 21 (or upper runner 22) provided at each left end of the one sliding door 1a and the other sliding door 1b. Two auxiliary rollers 25b having a high height project upward at a position shifted to the side, and are shifted to the rear side of the upper surface of the upper runner 23 provided at the right end of the central sliding door 1c. A double auxiliary roller 25b composed of two auxiliary rollers 25b having a high height protrudes upward, and the upper runner 23 provided at the left end of the central sliding door 1c Two low in height at a position shifted to the front side of the upper surface Twin auxiliary rollers 25a constituted by auxiliary rollers 25a are are projected upward.

  The branch member 18 is provided on the lower surface of the upper rail 5 and is provided at each branch point of the outer curved rail portion 11, the inner curved rail portion 12, and the curved rail portion 13 shown in FIG. It consists of auxiliary rails 18a to 18f having an inverted U-shaped cross section that opens downward. The auxiliary rail 18a is formed along the outer curved rail portion 11 at a position shifted to the front side of the left outer curved rail portion 11, and the auxiliary rail 18b is a rear side of the left inner curved rail portion 12. The auxiliary rail 18c is formed along the outer curved rail portion 11 at a position shifted to the rear side of the right outer curved rail portion 11. The auxiliary rail 18 d is formed along the inner curved rail portion 12 at a position shifted to the front side of the right inner curved rail portion 12, and the auxiliary rail 18 e is formed on the left curved rail portion 13. The auxiliary rail 18f is formed along the curved rail portion 13 at a position shifted to the rear side of the right curved rail portion 13 at a position shifted to the front side. A.

  The auxiliary rails 18a, 18d, and 18f are suspended downward from the lower surface of the upper rail 5, and the auxiliary rails 18b, 18c, and 18e are suspended downward from the lower surface of the upper rail 5.

  Then, the roller block 24 having the short double auxiliary rollers 25a shown in FIG. 8 does not interfere with the short auxiliary rails 18a, 18d, and 18f (FIG. 11), and the long auxiliary rail 18b, 18c, 18e (FIG. 11) can be bent, while the roller block 24 having the tall double auxiliary roller 25b (FIG. 12) is connected to the short auxiliary rails 18a, 18d, 18f. It can be turned along. Accordingly, by moving the roller block 24 having the short double auxiliary rollers 25a along the rear B of the front linearly-moving rail portion 9, the hanging length can be reduced without causing interference with the short hanging rails 18a and 18d. On the other hand, the roller block 24 having the tall dual auxiliary rollers 25b is moved in front A of the front linear rail portion 9 by moving the auxiliary rails 18b, 18c long, so that the auxiliary rail having a short drooping length is provided. It is guided by 18a and 18d.

  Next, the interlocking mechanism 15 will be described. As shown in FIG. 8, inclined interlocking metal fittings 15a that protrude from the upper end of one sliding door 1a toward the moving path C of the central sliding door 1c are attached to the upper ends of the one sliding door 1a and the other sliding door 1b, respectively. It has been. Receiving members 15e that can be engaged with and disengaged from the inclination interlocking metal fitting 15a are respectively attached to upper ends of both sides of the central sliding door 1c. The slant interlocking metal fitting 15a and the receiving member 15e constitute an interlocking mechanism 15 for transmitting the operating force on the one sliding door 1a side to the central sliding door 1c and opening and closing the central sliding door 1c in conjunction with the one sliding door 1a. .

  Here, as shown in FIG. 9, the inclined interlocking metal fitting 15a has a push-side inclined guide surface 15b that is inclined so as to be located in a direction opposite to the opening direction D of the one sliding door 1a from the proximal end to the distal end. And a locking surface 15c that bends in the opening direction D of the one-side sliding door 1a from the front end of the push-side inclined guide surface 15b, and a front-end inclined guide surface 15b that is substantially parallel to the front end of the locking surface 15c. The pulling-side inclined guide surface 15d protruding in this manner is integrally formed. Here, in order to efficiently transmit the operating force on the one sliding door 1a side to the central sliding door 1c, the push-side inclined guide surface 15b and the pulling-side inclined guide surface 15d are perpendicular to the moving path C of the central sliding door 1c. It is most preferable to incline. In a state where the one sliding door 1a and the central sliding door 1c are shifted to the left and right, the receiving member 15e does not interfere with the inclination interlocking metal fitting 15a, and the receiving member 15e is pushed on the push side when the one sliding door 1a and the central sliding door 1c substantially overlap. The receiving member 15e is pushed by the push-side inclined guide surface 15b at a stage where the one-side sliding door 1a and the central sliding door 1c are separated from each other back and forth across the other sliding door 1b. The pushing operation force acts in a direction substantially parallel to the moving path C of the central sliding door 1c, and when closing, the central sliding door 1c is in a state where the receiving member 15e is locked to the locking surface 15c. The receiving member 15e is pulled toward the pulling-side inclined guide surface 15d just before the end of the interlocking, and the pulling operation force P2 approaches the direction substantially parallel to the moving path C of the central sliding door 1c. It is intended to use.

  In this example, the receiving member 15e is constituted by a roller.

  Next, the operation will be described. For example, as shown in FIGS. 1 and 6, when the right one sliding door 1a is moved and opened in the opening direction D, the receiving member 15e is tilted interlocking metal fittings when the one sliding door 1a and the central sliding door 1c are shifted left and right. 15a, the receiving member 15e comes into contact with the inclined guide surface 15b on the push side of the inclination interlocking metal fitting 15a at the stage where the one sliding door 1a and the central sliding door 1c substantially overlap, and the one sliding door 1a and the central sliding door 1c As shown in FIG. 9 (a), the receiving member 15e is pushed by the base end side of the push-side inclined guide surface 15b, and the pushing operation force P1 is increased. It acts in a direction substantially parallel to the movement path C of the central sliding door 1c. That is, an operating force P1 parallel to the movement path C of the central sliding door 1c (the rail direction of the curved rail portion 13) is applied to the receiving member 15e at any position from the proximal end to the distal end of the push-side inclined guide surface 15b. Since it acts, there is no loss of force, and the central sliding door 1c is smoothly opened obliquely rearward. 1 (b) → (c) → (d), when the central sliding door 1c and the one sliding door 1a are separated from each other in the front-rear direction, the receiving member 15e is locked to the locking surface 15c of the tilt interlocking metal fitting 15a. This locked state is maintained until the one sliding door 1a and the central sliding door 1c reach the fully open position.

  On the contrary, when the one sliding door 1a is moved and closed in the closing direction E, the one sliding door 1a and the central sliding door 1c are closed in conjunction with each other while the receiving member 15e is locked to the locking surface 15c. In the stage immediately before the end of the interlock, as shown in FIG. 9B, the receiving member 15e is pulled by the inclined guide surface 15d on the pulling side, and the pulling operation force P2 is in a direction substantially parallel to the moving path C of the central sliding door 1c. Acts towards. Thereby, like the case of FIG.9 (a) opening, there is no loss of force and the center sliding door 1c can move to diagonally forward smoothly. When the central sliding door 1c reaches the closed position, as shown in FIGS. 1 (d) → (c) → (b), the receiving member 15e is released from the inclined guide surface 15d on the pulling side, and the interlocking is released. Can move to the closed position alone.

  According to the above configuration, since the one-way sliding door 1a and the central sliding door 1c can be interlocked by the interlocking mechanism 15, it becomes unnecessary to manually open and close the central sliding door 1c, and the opening / closing operation becomes extremely easy, and the interlocking mechanism 15 Since the push-side inclined guide surface 15b, the locking surface 15c, and the pull-side inclined guide surface 15d are integrally formed, cost can be reduced.

  Furthermore, the push-side inclined guide surface 15b and the pull-side inclined guide surface 15d of the interlocking mechanism 15 are inclined in a direction opposite to the opening direction D (FIG. 9) of the one sliding door 1a as the tip ends. Therefore, in the interlocking start stage of the one sliding door 1a and the central sliding door 1c, the direction of the pushing operation force P1 applied from the inclined guide surface 15b on the pushing side of the one sliding door 1a to the receiving member 15e of the central sliding door 1c is the direction of the central sliding door 1c. Since it is substantially parallel to the movement path C, the pushing operation force P1 of the one sliding door 1a can be efficiently transmitted to the central sliding door 1c. Further, in the stage immediately before the end of the interlocking of the one sliding door 1a and the central sliding door 1c, the direction of the pulling operation force P2 applied from the inclined guide surface 15d on the pulling side of the one sliding door 1a to the receiving member 15e of the central sliding door 1c is the movement of the central sliding door 1c. Since it is substantially parallel to the path C, the pulling operation force P2 of the one sliding door 1a can be efficiently transmitted to the central sliding door 1c, and as a result, in both cases, the central sliding door 1c can be smoothly opened and closed. . That is, almost all of the operation force P1 (P2) contributes to the movement of the central sliding door 1c, and the loss of force can be eliminated, so that a small operation force is sufficient. As a result, the opening / closing operability is greatly improved.

  Moreover, since the receiving member 15e is composed of a roller, the friction between the inclined interlocking metal fitting 15a and the receiving member 15e is minimized as much as possible at the start of interlocking and immediately before the end of interlocking. Further reduction can be achieved.

  Moreover, in this example, as shown in FIG. 1, the receiving member 15e is attached to the both ends of the central sliding door 1c, respectively, and the right end (the handle side) of the one sliding door 1a and the left end (the handle side) of the other sliding door 1b, Since the tilt interlocking metal fitting 15a is attached, the interlocking mechanism 15 works in either case of left opening or left opening. That is, in the fully closed state where the three sliding doors 1 are arranged in a line without any step, the other sliding door 1a is moved toward the one sliding door 1a (in the embodiment, the other sliding door 1b which is the left sliding door 1 is moved). The central sliding door 1c is moved in conjunction with the other sliding door 1b by the interlocking mechanism 15, and the other sliding door 1b is guided by the guiding mechanism 19 so as to overlap the front side of the one sliding door 1a. 1c can be guided to overlap the rear side of the one sliding door 1a, and can be opened so that the other sliding door 1b, the one sliding door 1a, and the central sliding door 1c are stacked in this order from the front.

  Note that a lower roller 27 protrudes from one central portion of the lower end of each sliding door 1. The lower roller 27 is attached to the center position of each lower end of the sliding doors 1 to 3 via an L-shaped bracket (not shown). As shown in FIG. 5, the lower rail 6 that guides the lower roller 27 is provided with left and right curved rail portions 42 and 43 that incline toward the rear B from both ends in the longitudinal direction M of the common rail portion 101, respectively. In addition, one curved rail portion 44 that is curved in a semicircular shape toward the front A from the central portion of the central sliding door rail portion 102 that is parallel to the common rail portion 101 and located on the rear side is provided. In addition, 45 in FIG. 5 is a branching auxiliary rail.

  Here, the position of the curved rail portion 42 on the left side of the lower rail 6 is opposed to the intermediate position between the outer curved rail portion 11 and the inner curved rail portion 12 on the left side of the upper rail 5. The position of the right curved rail portion 43 of the upper rail 5 is opposed to the intermediate position between the right outer curved rail portion 11 and the inner curved rail portion 12 of the upper rail 5, and the curved rail portion 44 of the lower rail 6 The position is opposite to the intermediate position between the left and right curved rail portions 13, 13 of the upper rail 5.

  And the upper end part of each sliding door 1 is suspended and supported by two right and left upper runners 21 (22, 23), while the three sliding doors 1 are flush with each other and closed, the lower roller 27 of the sliding door 1a. Is located at the rear end portion of the right curved rail portion 43, the lower roller 27 of the central sliding door 1c is located at the front end portion of the curved rail portion 44, and the lower roller 27 of the sliding door 1b is located on the left curved rail portion. 42 is located at the rear end. 6C, the lower roller 27 of the other sliding door 1b is positioned at the rear end of the left curved rail portion 42, and the lower roller 27 of the first sliding door 1a is a straight line of the common rail portion 101. The lower roller 27 of the central sliding door 1c is positioned at the left end of the straight portion of the central sliding door rail portion 102. 7C, the lower roller 27 of the sliding door 1a is positioned at the rear end of the right curved rail portion 43, and the lower roller 27 of the other sliding door 1b is a straight line of the common rail portion 101. The lower roller 27 of the central sliding door 1c is positioned at the right end of the straight portion of the central sliding door rail portion 102.

  As described above, the lower end portion is guided to the lower rail 6 by one lower roller 27. As a result, the running of each sliding door 1 can be sufficiently stabilized, and by using one lower roller 27, There is also an advantage that the groove shape of the lower rail 6 can be made simpler than the groove shape of the upper rail 5 and the cost of the lower rail 6 can be reduced.

  By the way, in the sliding door device having the above-described configuration, for example, when the three sliding doors 1 are arranged substantially in a line to be in the fully closed state, for example, the open state in which the three sliding doors 1 in FIG. 1, the one sliding door 1 a overlapping the front of the other sliding door 1 b is moved in the closing direction (that is, the left and right upper runners 21 of the one sliding door 1 a are moved to the right along the front straight rail 9), and the interlock mechanism 15 The left and right upper runners of the central sliding door 1c are moved by the guide mechanism 19 as shown in FIG. 1 (d) → (c) → (b). 23 are inserted into the respective front end portions of the two left and right curved rail portions 13, and then the one sliding door 1 a is moved along the front straight traveling rail portion 9 and the left and right upper runners 21 of the one sliding door 1 a are moved along the front straight traveling rail portion 9. The right upper runner 21 is introduced into the right outer curved rail portion 11 and the left upper runner 21 is introduced into the right inner curved rail portion 12 so that the one-side sliding door 1a is moved to the right side. In the closed state, the one sliding door 1a is shifted to the rear side, and the left and right upper runners 21 of the one sliding door 1a are respectively moved to the rear end portion of the right outer curved rail portion 11 and the right inner curved rail portion. 12 so that the left and right runners 22 are positioned at the rear end portion of the left outer curved rail portion 11 and the rear end portion of the left inner curved rail portion 12, respectively. In this case, the other sliding door 1b and the left and right upper runners 23 are continuously flush with the central sliding door 1c located at the front ends of the two left and right curved rail portions 13, but in this case , Left and right upper runners of sliding door 1a 21 at the rear end of the right outer curved rail portion 11 and the rear end of the right inner curved rail portion 12, that is, the left and right upper runners 21 of the sliding door 1a Even when it is introduced into the outer curved rail portion 11 and the right inner curved rail portion 12 and stops near the rear end without reaching the rear end, almost three sliding doors 1 are fully closed. In some cases, a step is slightly formed between the front surface of the central sliding door 1c and the front surface of the one-side sliding door 1a and is not continuous. That is, as shown in FIG. 17 (a), there is a case where a slight step is formed and the valve is almost fully closed.

  In addition, even when the three sliding doors 1 are continuously closed so that there is no step, when an external force is applied to the one sliding door 1a or the other sliding door 1b, the upper runner 21 and the upper runner 22 are outside. It moves slightly forward from the rear end portion of the curved rail portion 11 and the rear end portion of the inner curved rail portion 12, and a slight gap is formed between the front surface of the one sliding door 1a or the other sliding door 1b and the front surface of the central sliding door 1c. May be possible.

  However, in such a fully closed state with a slight level difference, for example, when the right side other sliding door 1b is moved to the one sliding door 1a side to open, the front side of the one sliding door 1a as shown in FIG. Slightly protrudes forward from the central sliding door 1c, there is a possibility that the end of the other sliding door 1b collides with the side end of the first sliding door 1a and cannot be opened.

  Therefore, in the present invention, the three sliding doors 1 are fully closed, and the three sliding doors 1 are provided in a flush state to hold the closed state. The person knows that it is held by the flush state holding means 2 from the feeling of the hand at the time of operation or the like, and is held by the flush state holding means 2 to hold the flush state, so that the fully closed state When the closing operation is performed by moving the one sliding door 1a toward the other sliding door 1b or moving the other sliding door 1b toward the one sliding door 1a, the leading end on the moving side of the one sliding door 1a is the other. The three sliding doors 1 are smoothly opened in the front-rear direction without colliding with the end of the sliding door 1b or the moving side tip of the other sliding door 1b colliding with the end of the one sliding door 1a. Can be done.

  FIGS. 13 and 14 show an example of the flush state holding means 2. In the present embodiment, both side portions of the rear end portion of the left and right outer curved rail portions 11 of the upper rail 5, both side portions of the rear end portion of the left and right inner curved rail portions 12, and two left and right curved rails. The upper roller 26 of the runners 21, 22, and 23 is connected to the concave portion 2 a or the rear portion in the state where the concave portions 2 a or convex portions are respectively provided on the front and rear portions of the portion 13 and the three sliding doors 1 are closed in a line. It is comprised so that it may engage with a convex part, and the three sliding doors 1 are located in a line by making the upper roller 26 of runner 21,22,23 engage with the recessed part 2a or a convex part. It is the flush-closed holding means 2 that holds the closed state. In FIG. 13, the upper rail 5 is provided with the recess 2a, and the runners 21, 22, and 23 are fitted and engaged with the recess 2a in the closed state to keep the closed state. It is like that. 14A shows a state in which the upper roller 26 of the runner 21 (22) is not fitted in the recess 2a, and FIG. 14B shows a state in which the upper roller 26 of the runner 21 (22) is fitted in the recess 2a. In the state shown in FIG. 14B, the closed state is maintained.

  When the user performs the closing operation, the upper roller 26 of the runners 21, 22, 23 is engaged with the concave portion 2 a or the convex portion, so that the touch transmitted to the hand at the time of engagement, for example, the upper surface of the runners 21, 22, 23 It is possible to know the state that the roller 26 is fitted and engaged in the concave portion 2a and the feeling that the roller 26 gets over and engages the convex portion, and the state that the roller 26 is closed is inadvertent. Even if an external force acts on the one sliding door 1a or the other sliding door 1b, the flushing state holding means 2 keeps the three sliding doors 1 being closed in a flush manner, resulting in an inadvertent step. Do not do.

  On the other hand, when the three sliding doors 1 are closed in a flush state and the one sliding door 1a or the other sliding door 1b is moved to perform an opening operation, a force greater than the holding force by the flush state holding means 2 is applied. By moving the upper roller 26 and the concave portion 2a or the convex portion, the opening operation can be performed by overcoming the engagement between the upper roller 26 and the concave portion 2a.

  FIGS. 15 and 16 show another embodiment of the flush close state holding means 2 that holds the closed state in which the three sliding doors 1 are fully closed and the three sliding doors 1 are flush with each other. .

  That is, in FIG. 15, the magnets 2b are projected from the left and right vertical frames 4a of the door frame 4, and a magnetic body 2c such as a metal plate is provided on the rear surface of the right side end of the one sliding door 1a, while the other sliding door is provided. A magnetic body 2c such as a metal plate is provided on the rear surface of the left side end of 1b, and the magnetic bodies 2c of the one sliding door 1a and the other sliding door 1b in a state where the three sliding doors 1 are closed in a line. Are magnetically attached to the magnets 2b projecting from the left and right vertical frames 4a, so that the three sliding doors 1 are kept in line and closed.

  In FIG. 16, magnets 2b are embedded in the left and right vertical frames 4a of the door frame 4, and a magnetic body 2c such as a metal plate is provided on the right side surface of the one sliding door 1a and the left side of the other sliding door 1b. A magnetic body 2c such as a metal plate is provided on a side end surface portion, and the magnetic bodies 2c of the one sliding door 1a and the other sliding door 1b are respectively left and right vertical frames 4a in a state where the three sliding doors 1 are aligned and closed. The two sliding doors 1 are arranged in a line and kept closed by being magnetized on the magnet 2b provided on the surface.

  In the present embodiment, when the user performs a closing operation, the user can know the closed state by the hand feeling when the magnet 2b is magnetically attached to the magnetic body 2c, and also the closed state. Then, even if an inadvertent external force acts on the one sliding door 1a or the other sliding door 1b, the state in which the three sliding doors 1 are closed flush with the flush state holding means 2 comprising the magnet 2b and the magnetic body 2c is maintained. As a result, no step is inadvertently generated.

  On the other hand, when the three sliding doors 1 are closed in a flush state and the one sliding door 1a or the other sliding door 1b is moved to perform an opening operation, the magnet 2b and the magnetic material constituting the flushing state holding means 2 are used. The opening operation can be performed by applying a force greater than the adsorption force of 2c and moving it.
