  The guide lever 5 is engaged with a cam rail 7 which will be described in detail later, and transmits the control action of the sliding door 1 by the cam rail 7 to the parallel link 4. The guide lever 5 has a base end portion 51 provided on the inner side of the base end portion 42 side of one link arm 41 of the parallel link 4 (in this embodiment, the link arm 41 located closer to the right sliding door 1R). In addition, a driven roller 53 that engages with the cam rail 7 is pivotally attached to the distal end portion 52 thereof. Further, the guide lever 5 is formed with a standing portion 54 at a substantially central portion thereof, and the standing portion 54 is inserted into the slit 34 of the traveling plate 31 of the runner 3, and the base end portion is extended from the standing portion 54. Like the parallel link 4, the 51 side is disposed on the lower surface side of the traveling plate 31 of the runner 3, while the tip portion 52 side from the standing portion 54 is disposed on the upper surface side of the traveling plate 31. The outer diameter of the driven roller 53 is slightly smaller than the distance between the side plate portion 62 of the traveling rail 6 and the straight portion 72 of the cam rail 7 which will be described in detail later. Furthermore, in this embodiment, as a guide lever locking means for locking the guide lever 5 when the door is closed, small-diameter engaging holes 55 are formed between the upright portion 54 and the base end portion 51 at two locations. Correspondingly, lock members 56 that respectively engage with the engagement holes 55 are suspended from the lower surface of the travel plate 31 of the runner 3. As the lock member 56, for example, a small ball that easily engages and disengages from the engagement hole 55 and a spring that biases the small ball outward (to the engagement hole 55 side) are housed in a case. The engaging hook can be employed. The guide lever locking means is not limited to the above-described form. For example, a gripping member that elastically grips the standing portion 54 of the guide lever 5 from the side edge side is used as the lower surface of the travel plate 31 of the runner 3. The thing provided in the right place may be sufficient. As is well known in the art, a plate made of a magnetic material is provided at an appropriate position on the rear surface of the sliding door 1, and a magnet corresponding to the plate is provided at an appropriate position in the opening A, and the sliding door 1 is closed by magnetic attachment of the magnet and the plate. When the state is maintained, the above-described guide lever lock means may be omitted.

  The running rail 6 is provided in the opening A, and runs the runner 3 parallel to the opening surface of the opening A while supporting the runner 3 via the main rolling roller 33. It is provided outside the lower edge side of the opening A. The running rail 6 has a length substantially the same as the opening width of the opening A, and is slightly larger than the width dimension of the runner 3 (the dimension between the outer surfaces of the opposing main rolling rollers 33). , A pair of side plate portions 62 suspended from both side edges of the base portion 61, and a rail portion 63 extending from the side plate portions 62 so as to face each other. . The height dimension of the side plate portion 62 is slightly larger than the outer diameter of the main rolling roller 33 of the runner 3. Of the pair of rail portions 63, the rail portion 63 on the side corresponding to the main rolling roller 33 having the groove 331 of the runner 3 has a ridge portion that matches the groove 331 of the main rolling roller 33. 64 is provided over the entire length, so that the runner 3 does not shake in the direction orthogonal to the traveling direction during traveling.

  The cam rail 7 is engaged with the driven roller 53 of the guide lever 5 in order to control the distance between the sliding doors 1 in the sliding movement and the sliding movement between the flushing state and the sliding movement of each sliding door 1. Thus, the driven roller 53 travels along a predetermined track, and is suspended from the lower surface of the base portion 61 of the travel rail 6 described above. Both ends of the cam rail 7 are formed in curved portions 71 along the rotation locus of the driven roller 53 of the guide lever 5, and a straight line parallel to the side plate portion 62 of the traveling rail 6 is formed between the curved portions 71. A portion 72 is formed. The length of the curved portion 71 is long enough to swing the link arm 41 of the parallel link 4 via the driven roller 53 of the guide lever 5 until the separation distance between the sliding doors 1 in the retracted state is secured. Has been.

  The support arm 8 is provided on the rear surface of each of the left and right sliding doors 1 so as to have a vertically symmetrical positional relationship with the bracket 2. The support arm 8 includes an L-shaped saddle member 81 and a sub-rolling roller 82 that is rotatably provided at the tip of the support arm 8.

  The guide rail 9 causes the auxiliary rolling roller 82 of the support arm 8 to travel along a trajectory corresponding to the travel trajectory of the driven roller 53 of the guide lever 5, and in this embodiment, the upper edge side of the opening A. It is buried in the inside. Both ends of the guide rail 9 are curved portions 91 similar to the cam rail 7, and a straight portion 92 parallel to the traveling rail 6 is formed between the curved portions 91.

  In the above embodiment, only the lower end portion of each sliding door 1 is supported by the traveling rail 6 via the bracket 2 and the parallel link 4, but the traveling rail 6 is also provided on the upper edge side of the opening A to provide the upper end portion. May be supported in the same manner as the lower end. In that case, the support arm 8 and the guide rail 9 described above are unnecessary.

  Moreover, in the said embodiment, although the traveling rail 6 is provided in the outer side of the lower edge side of the opening part A, you may provide in the inner side of the opening part A. In that case, the traveling rail 6 is kept on the inner surface of the opening A while maintaining the top and bottom of the traveling rail 6 so that a clearance enough to allow the parallel link 4 to swing is secured between the traveling rail 6 and the inner surface of the opening A. It only has to be attached. Furthermore, when the traveling rail 6 is provided on the inner surface on the upper edge side of the opening A, the top and bottom may be reversed from the case where it is provided on the lower edge side. Furthermore, when the traveling rail 6 is provided on the outer side of the upper edge side of the opening A, the parallel link 4 is swung while the traveling rail 6 is left as it is, as in the case of being provided on the inner side of the opening A described above. What is necessary is just to attach to the outer surface of the opening part A, ensuring the gap which can be performed between the running rail 6 and the outer surface of the opening part A. FIG. In short, regardless of the upper edge, the lower edge, and the inside and outside of the opening A, the base 61 of the traveling rail 6 is attached to the opening A so that the foreign matter enters the traveling rail 6. It is preferable not to do so.

  Next, operation | movement of an above-described flat sliding door apparatus is demonstrated.

  When both the sliding doors 1 are in the door closed state, as shown in FIG. 1, the runner 3 is positioned at the end of the traveling rail 6, and the parallel link 4 is in a tilted state. Accordingly, the driven roller 53 of the guide lever 5 is positioned at the start end of the curved portion 71 of the cam rail 7, the engagement hole 55 and the lock member 56 are in an engaged state, and the guide lever 5 is in a locked state. For this reason, the sliding door 1 does not escape from the door closed state unless an external force is applied.

  From this state, when the sliding door 1 (here, the left sliding door 1L) is pulled forward with the handle provided at the appropriate position, the engagement between the engagement hole 55 of the guide lever 5 and the lock member 56 is released, The parallel link 4 comes to the front from the tilted state, the guide lever 5 swings integrally with the link arm 41 of the parallel link 4, and the driven roller 53 of the guide lever 5 moves along the curved portion 71 of the cam rail 7. Roll. At this time, the sliding doors 1 do not interfere with each other because the end surfaces of the sliding doors 1 are inclined surfaces 11 facing the inside of the opening A.

  When the sliding door 1 is further pulled, the driven roller 53 of the guide lever 5 eventually reaches the end of the curved portion 71 of the cam rail 7 and enters the beginning of the linear portion 72 at the same time. As a result, the left sliding door 1L and the right sliding door 1R have completed the variable movement operation from the flush state to the sliding state. Here, even if the sliding door 1 is further pulled forward, the driven roller 53 of the guide lever 5 reaches the start end of the straight portion 72 of the cam rail 7, and thus the swing of the guide lever 5 is prevented by this straight portion 72. Thus, the swinging motion of the parallel link 4 is stopped at this point, and the pulling state is determined.

  When the sliding door 1 is pulled in the right direction in a state where the sliding state is confirmed, the runner 3 travels along the traveling rail 6 and the sliding door 1 moves smoothly. At this time, the driven roller 53 of the guide lever 5 rolls on the straight portion 72 of the cam rail 7, whereby the posture of the parallel link 4 maintains the posture at the time of the above-described difference state determination. Thus, the separation distance between the sliding doors 1 is kept constant.

  When returning to the door-closed state again, the sliding door 1 in the sliding state is pulled back, and when the driven roller 53 of the guide lever 5 eventually reaches the curved portion 71 from the straight portion 72 of the cam rail 7, the guide lever 5 by the straight portion 72 described above. The parallel link 4 swings in a tilting direction so as to receive a force in the pull-back direction applied to the sliding door 1, and accordingly the sliding door 1 is in a flush state from the retracted state. Transition to. When the sliding door 1 is pressed, the parallel link 4 is further swung, and the engagement hole 55 of the guide lever 5 and the lock member 56 are engaged with each other, and the guide lever 5 is locked. As a result, the sliding door 1 is brought into the door closed state. At the same time, the door is closed.

  The flat sliding door device according to the present invention can be used as an opening / closing device for an opening of furniture such as a costume basket or a kitchen cabinet, or as an opening / closing device for opening / closing an opening of a building such as a closet or a bag cabinet. is there.

It is a notch partial top view which shows one Embodiment of the flat sliding door apparatus which concerns on this invention, and shows the left sliding door side of the flat sliding door apparatus in a door closed state. It is the II-II arrow directional view shown in FIG. 1 including the upper part of a sliding door. It is a notch partial top view which shows the left sliding door side of the flat sliding door apparatus just before completing the change movement work from the door closed state to a door open state. FIG. 4 is a view taken along the line IV-IV in FIG. 3 including the upper part of the sliding door (however, the main rolling roller appearing in front of the driven roller is not shown). It is the figure looked up from the inner side of the opening part which shows operation | movement of the support arm accompanying the variable movement operation | movement between the flush state of a left sliding door, and a sliding state.
