It abuts against the abutment piece 51 provided on the left side.

  Then, when the second door body 23 is moved toward the right side when viewed from the front in this state, the second door body 23 is positioned on the front side of the door interlocking device 41 together with the fitting body 31 of the pivot shaft 26 on the left side when viewed from the front. The transmitting body 64 to be moved moves to the right in the front view.

  At this time, the belt body 61 of the door interlocking device 41 rotates counterclockwise as viewed from above by the movement of the front transmission body 64 into which the pivot shaft 26 of the second door body 23 is fitted. Therefore, the rear transmission body 64 into which the pivot shaft 26 of the third door body 24 different from the front transmission body 64 is fitted and moved moves to the left in the front view with respect to the first door body 22. The first door body 22 is interlocked to the right side when viewed from the front.

  Then, when the second door body 23 is further moved toward the right side of the front view, the front transmission body 64 in which the pivot shaft 26 of the second door body 23 is inserted is inserted into the base plate portion 43 of the door interlocking device 41. And the rear transmission body 64 into which the pivot shaft 26 of the third door body 24 is inserted is inserted to the left end portion of the board portion 43 of the door interlocking device 41. As the second door body 23 moves, the first door body 22 further moves to the right in the front view.

  At this time, the shaft body 29 of the pivot shaft 26 located on the right side of the second door body 23 in front view is engaged with the stopper member 75 attached between the pair of second engaging claws 16 of the integrated upper rail 11. Locked to the stopper 76. As a result, the entire opening 3 is closed by each of the first door body 22, the second door body 23, and the third door body 24.

  Further, when the second door body 23 is moved toward the left side of the front view from this state, the shaft body 29 of the pivot shaft 26 located on the right side of the second door body 23 is moved upward. This is disengaged from the latch receiving portion 76 of the stopper member 75 attached between the pair of second engaging claws 16.

  Thereafter, the transmission body 64 into which the pivot shaft 26 located on the left side of the second door body 23 is inserted is moved toward the left side of the front door. The first door together with the second door body 23 is moved to the first door. The body 22 is interlocked toward the left side when viewed from the front.

  As a result, when the second door body 23 is further moved toward the left side in the front view, the first door body 22, the second door body 23, and the third door body 24 are located on the left side in the front view of the opening 3. Are overlapped, and the left side and the center of the opening 3 in the front view are opened.

  As described above, according to the first embodiment, the sliding hole 66 of each transmission body 64 of the door interlocking device 41 is arranged in the longitudinal direction along the width direction of the substrate portion 43 of the door interlocking device 41. It was formed in the shape of a long hole having. As a result, the distal end portion of the fitting body 31 of the pivot shaft 26 inserted into the sliding hole portion 66 of each of the transmission bodies 64 extends along the width direction of the substrate portion 43, that is, the thickness direction of the first door body 22. It is loosely fitted so as to be movable by a predetermined distance.

  Therefore, when these first door body 22, second door body 23, and third door body 24 have different thicknesses, or when these first door body 22, second door body 23, and third door body 24 are different in thickness. Even in the case where the gaps between the door bodies 24 are different, the first movement of the pivot shaft 26 in the sliding hole portion 66 of each transmission body 64 along the thickness direction of the first door body 22 makes these first The thickness change and gap change of the door body 22, the second door body 23, and the third door body 24 can be absorbed. For this reason, even when the thickness and gap of the first door body 22, the second door body 23, and the third door body 24 are different, the common door interlocking device 41 can be used.

  Specifically, as in the second embodiment shown in FIGS. 4 and 5, the thickness of each of the first door body 22, the second door body 23, and the third door body 24 is 26 mm to 32 mm. Even when the thickness is increased, the first door body 22, the second door body 23, and the third door body are moved by the movement of the pivot shaft 26 in the sliding hole 66 of each transmission body 64. Can absorb 24 thickness changes. Accordingly, even if the first door body 22, the second door body 23, and the third door body 24 are integrated upper rails 11 having different thickness specifications and different spacing specifications, the door interlocking device 41 is commonly used. Can be used.

  Furthermore, a part of the belt body 61 that is rotatably supported between a pair of pulleys 45 attached to both ends along the moving direction of the first door body 22, and the second door body 23 and the second door body 23 are supported. Each of the three door bodies 24 is connected by a transmission body 64. As a result, the belt body 61 is rotated between the pair of pulleys 45 so that the second door body 23 and the third door body 24 are continuously interlocked with the first door body 22 so-called belts. Even the door interlocking device 41 of the type type can absorb the thickness change and the gap change of the first door body 22, the second door body 23, and the third door body 24.

  Further, the engagement groove portions 73 of the respective transmission bodies 64 are slidably engaged with the engagement piece portions 49 provided on both side edges of the substrate portion 43 of the door interlocking device 41. As a result, when each of the transmission bodies 64 is moved by the rotation of the belt body 61, a lateral shake that is a direction orthogonal to the movement direction of each of the transmission bodies 64 is caused by the engagement piece portion 49 of the base plate portion 43. This is prevented by the engagement of the engagement groove 73 of the transmission body 64. Therefore, it is possible to reliably prevent the lateral shaking when each of the transmission bodies 64 moves with a simple configuration.

  Further, since the portion to be engaged with the sliding hole portion 66 of each transmission body 64 of the door interlocking device 41 is a part of the traveling body that is the fitting body 31 of the pivot shaft 26, the sliding holes of these transmission bodies 64 Since the number of parts of the door interlocking device 41 can be reduced compared to the case where the member to be locked to the portion 66 is formed separately from the fitting body 31 of the pivot shaft 26, the manufacturing cost of the door interlocking device 41 can be reduced.

In the above-described first embodiment, without attaching indirectly to the base plate portion 43 the upper end surface of the first door member 22, directly the substrate portion 43 on the upper end face of the first door member 22 It can also be configured to be attached to. That is, the interlocking device main body 42 of the door interlocking device 41 is attached to the upper end surface of the first door body 22 by screwing directly without engaging the interlocking device main body 42 with the upper rail 11 slidably. You can also.

It can also be set as the structure expanded. In this case, it is possible to more easily fit the distal end portion of the fitting body 31 of the pivot shaft 26 into the sliding hole portion 66 of each of the transmission bodies 64. Accordingly, the second door body 23 and the third door body 24 can be attached to the door interlocking device 41 more easily, so the second door body 23 and the third door body 24 to the integrated upper rail 11 can be obtained. Can be built more easily.

  Further, as in the second related art shown in FIG. 7, the sliding hole 66 of each transmission body 64 of the door interlocking device 41 is replaced with the first door body 22, the second door body 23, and the third door. It can also be formed into a long hole shape in which the fitting body 31 of the pivot shaft 26 is movably fitted along the moving direction of each body 24. In this case, when one of the second door body 23 and the third door body 24 is moved and the first door body 22, the second door body 23, and the third door body 24 are interlocked. Further, the distal end portion of the fitting body 31 of the pivot shaft 26 fitted in the sliding hole portion 66 of the door interlocking device 41 can be slid within the sliding hole portion 66 by a predetermined distance in the moving direction.

  Therefore, when the opening 3 is closed by the first door body 22, the second door body 23, and the third door body 24, the first door body 22, the second door body 23, and the second door body 23 are closed. The overlap margin existing between each of the three door bodies 24 can be reduced. Therefore, when the opening 3 is opened by the first door 22, the second door 23, and the third door 24, the opening size of the opening 3 can be set wider.

  Further, as in the third related technique shown in FIG. 8, each transmission body 64 of the door interlocking device 41 is connected to the upper end surfaces of the second door body 23 and the third door body 24. The door body 23 and the third door body 24 can also be mounted so as to be adjustable in the thickness direction. In this case, a mounting base 81 as a mounting member is provided at least on the end portion on the left side of the upper end surface of the second door body 23 in the front view and on the right end portion of the upper end surface of the third door body 24 in the front view. Each is attached. The mounting base 81 is slidably fitted into the sliding grooves 18 and 19 of the integrally upper rail 11 and functions as the fitting body 31.

  Further, the mounting base 81 forms leg portions 83 by bending both ends of the elongated rectangular flat plate-like main body portion 82 downward at a substantially right angle, and the front ends of the leg portions 83 are opposed to each other. It is formed in a shape that is bent at a substantially right angle toward the direction to form a mounting portion 84. The mounting base 81 is arranged in a state where the longitudinal direction of the main body 82 of the mounting base 81 is aligned with the longitudinal direction of the upper end surface of the second door body 23 or the third door body 24.

The transmission body 65 has a width that is slightly smaller than the inner width between the legs 83 of the mounting base 81. That is, the transmission body 65 can move back and forth between the legs 83 of the mounting base 81 in a state where the mounting base 81 is mounted on the upper end surface of the second door body 23 or the third door body 24. Inserted to be adjustable in direction. At this time, the transmission body 65 has a length that is greater than the width of the body 82 of the mounting base 81.

  Further, a screwing hole 86 penetrating in the thickness direction of the transmission body 65 is formed at the center of each transmission body 64 in the width direction and the longitudinal direction of the transmission body 65. The screw hole 86 has a female thread portion formed by screwing a screw groove on the inner peripheral surface. The screw hole 86 is configured to communicate with the adjustment hole 85 of the mounting base 81 in a state where the transmission body 65 is inserted between the leg portions 83 of the mounting base 81.

  Further, a shaft 88 of a screw body 87 that can be screwed into the screw hole 86 is screwed into the screw hole 86 and attached thereto. The shaft portion 88 of the screw body 87 is a fitting insertion protrusion that is screwed into the screwing hole 86 of the transmission body 65 in a state where the shaft portion 88 is inserted into the adjustment hole 85 of the mounting base 81.

Each of the screw holes 86 is formed in a long hole shape having a longitudinal direction along the horizontal direction orthogonal to the moving direction of the transmission body 64. Here, one of these screw holes 86 is provided at a position near the base end on one side in the width direction of the transmission body 65. Further, the other of the screw holes 86 is provided at a position near the tip on the other side along the width direction of the transmission body 65.

  Further, an upper edge of a substantially rectangular flat plate-shaped mounting piece 89 protruding toward the lower side of each transmission body 64 is integrally formed on one side edge of each transmission body 64 in the width direction of the transmission body 65. It is connected. The attachment piece 89 has a longitudinal direction along the thickness direction of the transmission body 65 and a width direction orthogonal to the width direction of the transmission body 65. That is, the attachment piece 89 is in a state in which the transmission body 65 of the transmission body 64 is in contact with the upper end surface of the second door body 23 or the third door body 24. It is comprised so that it may contact | abut to the small edge surface which is one side surface in the width direction of the 3 door body 24. FIG.

  The mounting piece 89 has a plurality of, for example, two screw holes 86 formed therein. The screw holes 86 are also formed in a long hole shape having a longitudinal direction along the horizontal direction orthogonal to the moving direction of the transmission body 64. Here, one of these screwing holes 86 is provided at a position near the lower end on the tip side of the mounting piece 89. Further, the other of the screw holes 86 is provided at a position near the upper end on the base end side of the mounting piece 89. Accordingly, the shaft portion 88 of the screw body 87 inserted into the screw holes 86 is attached to the attachment piece 89 of the transmission body 64 in a state where the axial direction is aligned with the moving direction of the transmission body 64.

  As a result, the transmission body 65 of the transmission body 64 located on the front side of the door interlocking device 41 is brought into contact with the left end of the upper end surface of the second door body 23 as viewed from the front, and the transmission body 64 is attached. The piece 89 is brought into contact with the upper end side of the small edge surface of the second door body 23 on the left side when viewed from the front. In this state, the shaft portion 88 of the screw body 87 is inserted into the transmission body 65 of the transmission body 64 and the screwing hole 86 of the mounting piece 89, and the shaft portion 88 of the screw body 87 is connected to the second door body. The transmission body 64 is fixed to the second door body 23 with screws by screwing it to the upper end surface or the facet surface of 23.

  Similarly, the transmission body 65 of the transmission body 64 located on the rear side of the door interlocking device 41 is brought into contact with the right end of the upper end surface of the third door body 24 as viewed from the front. The attachment piece 89 is brought into contact with the upper end side of the small edge surface on the right side of the third door body 24 when viewed from the front. In this state, the shaft portion 88 of the screw body 87 is inserted into the transmission body 65 of the transmission body 64 and the screwing hole 86 of the mounting piece 89, and the shaft portion 88 of the screw body 87 is connected to the third door body. The transmission body 64 is screwed and fixed to the third door body 24 by directly screwing it to the upper end surface or the facet surface of 24.

It can move along the thickness direction. Therefore, the mounting position of the second door body 23 or the third door body 24 by the transmission body 64 is directed in the front-rear direction which is the thickness direction of the second door body 23 or the third door body 24. Since it can be adjusted, the same effect as the third related technique can be obtained.

  Further, the pivot shaft 26 attached to the upper end surface of the first door body 22 is configured so that the eccentric position of the shaft body 29 of the pivot shaft 26 on the upper end surface of the first door body 22 can be adjusted. That is, the pivot shaft 26 projects from a hexagonal flat nut body 90 attached to the upper end surface of the first door body 22. Further, the pivot shaft 26 protrudes on the nut body 90 that is eccentric with respect to the outer peripheral surface of the nut body 90. Therefore, by rotating the nut body 90, the pivot shaft 26 protruding from the nut body 90 moves in the width direction of the first door body 22, and the first pivot shaft 26 has a first axis. The front-rear position with respect to the upper end surface of the door body 22 is adjusted.

  Therefore, the gap between the first door body 22, the second door body 23, and the third door body 24 can be adjusted by the eccentricity of the pivot shaft 26 due to the rotation of the nut body 90. And even if it is a case where the change of the clearance gap between the 1st door body 22, the 2nd door body 23, and the 3rd door body 24 arises in this way, the sliding hole demonstrated in said each embodiment The first door body 22, the second door body 23, and the third door are formed by the fitting insertion hole which is the portion 66, the adjustment hole 85 and the screwing hole 86, and the fitting insertion protrusion which is the pivot shaft 26 and the shaft portion 88. The gap change of the door body 24 can be absorbed, and the front-rear adjustment of the first door body 22, the second door body 23, and the third door body 24 can be handled.
