Therefore, while attaching | subjecting the same code | symbol, in the following description, only the transmission body 60 located in a back side is demonstrated, and description of the transmission body 60 of the front side is abbreviate | omitted.

  As shown in FIGS. 9 and 10, the transmission body 60 is integrally formed of a resin material, and has a rectangular shape elongated in the opening and closing direction. In addition, the transmission body 60 is appropriately provided with a meat theft 65 to reduce its weight so that movement in the opening and closing direction can be smoothly performed.

  The mounting recess 63 and the engagement groove 64 described above are formed on the front side of the transmission body 60 on the door closing side. The stopper 51 of the endless wire 50 is assembled to the mounting groove 63 a of the mounting recess 63.

  Further, at a position slightly closer to the door opening side than the central portion of the transmission body 60, a door attachment hole 61 is vertically penetrated and provided. In addition, a mounting hole 62 for setting the remaining portion having the same shape as the door mounting hole 61 is provided on the outside in the opening and closing direction from the door mounting hole 61 (the door open side; the door closed on the front transmission member 60). It is done. The distance between the door attachment hole 61 and the left-attachment setting attachment hole 62 is equal to the length of the left-off L.

  As shown in FIG. 10, flange housing grooves 61a and 62a recessed downward from the lower surface of the transmission body 60 are respectively provided in the door attachment hole 61 and the attachment opening 62 for setting the remaining portion. A flange portion 93a of a switching pivot shaft 90, which will be described in detail later, is attached to the flange accommodation grooves 61a and 62a.

  Moreover, the position in the opening and closing direction of the door attachment hole 61 is such that the three doors 3, 4, 5 completely overlap in the front-rear direction with the three doors 3, 4, 5 attached. It is positioned so as to be open (see FIG. 2 (A)).

  Between the door mounting hole 61 and the remaining attachment setting mounting hole 62, a contact portion 66 which extends in the front-rear direction and protrudes upward is provided. The contact portion 66 comes in contact with the lower end portion of a guide rail R1 (see FIG. 4) which will be described in detail later.

  The switching pivot shaft 90 of the rear door 5 is inserted through either the door attachment hole 61 or the left-attachment setting attachment hole 62. The switching pivot shaft 90 is attached to the door closing side of the rear door 5, as shown in FIGS. 4 to 6, and either the door mounting hole 61 or the remaining attachment setting mounting hole 62. After being inserted, as shown in FIG. 4, the guide rail R <b> 1 embedded in the mounting recess 2 c of the housing 2 is attached. When the switching pivot shaft 90 is attached to the guide rail R1, the pivot shaft 90 can freely move in the opening and closing direction along the guide rail R2.

  In addition, on the door open side of the rear side door 5, as shown in FIG. 6, a pivot shaft 70 for suspending the rear side door 5 is provided. The pivot shaft 70 is a so-called conventional pivot shaft, which is directly attached to the guide rail R1 so as to freely move in the opening / closing direction along the guide rail R2.

  Further, the switching pivot shaft 90 and the pivot shaft 70 of the front door 3 are disposed symmetrically on the door opening side and the door closing side with the intermediate door 4 interposed therebetween. That is, as in the case of the rear door 5, the switching pivot shaft 90 of the front door 3 is inserted into either the door attachment hole 61 or the left-attachment attachment hole 62 of the transmission member 60 on the front side. Then, it is attached to the guide rail R1.

  The transmission body 60 has an elongated shape extending in the opening / closing direction by the amount of provision of the remaining attachment setting attachment hole 62 as compared with the conventional transmission body. Therefore, the tip end side of the transmission body 60 supported on the main body 20 side only by the mounting recess 63 and the engagement groove portion 64 is inclined downward, which makes it difficult to maintain a horizontal posture. Therefore, the door attachment hole 61, the left attachment setting attachment hole 62, and the switching pivot shaft 90 are devised to maintain this posture.

  FIG. 11A is a front view of the switching pivot shaft 90, and FIG. 11B is a right side view thereof. FIG. 12 is a perspective view of the switching pivot shaft 90 as viewed obliquely from above.

  The switching pivot shaft 90 is configured of a door attachment portion 91 attached to the door side, a shaft 92 extending upward from the door attachment portion 91, and a fitting portion 93 located above the shaft 92. It is done.

  The door attachment portion 91 and the shaft 92 have the same structure as the pivot shaft 70. As shown in FIG. 12, the fitting portion 93 is formed with a flange portion 93 a having a diameter larger than that of the shaft body 92. The flange portion 93a is formed in such a manner that the upper surface of the flange portion 93a is in contact with the lower surface of the flange housing groove 61a at the surface thereof.

  Further, in a state where the flange portion 93a is lifted upward, the contact portion 66 of the transmission body 60 abuts on the lower side of the guide rail R1 (see FIG. 4), and the position in the vertical direction is regulated. The contact portion 66 moves in the opening and closing direction while sliding on the lower side of the guide rail R1. Therefore, the transmission body 60 maintains a substantially horizontal posture over the entire length in the opening and closing direction.

  On the other hand, in the state in which the transmission body 60 is inclined, when the fitting portion 93 is inserted into the remaining attachment setting attachment hole 62, it is difficult for the respective centers to coincide with each other. Therefore, the diameter of the remaining attachment setting attachment hole 62 is made larger than the diameter of the fitting portion 93 of the pivot shaft 90 to facilitate insertion. However, when a gap is created between the inner side surface of the left unset setting attachment hole 62 and the outer peripheral surface of the fitting portion 93, the left untouched setting attachment hole 62 abuts on the fitted portion 93 when the door is opened or closed. A sound is produced. Therefore, the O-ring (buffer member) 93 b is provided in the fitting portion 93 to enhance the noise reduction.

  Next, the operation and operation of the opening and closing member interlocking device 10 according to the embodiment of the present invention will be described mainly with reference to FIGS. 13 and 14.

  When the front door 3 is moved in the opening direction from the state shown in FIG. 1, the opening / closing body interlocking device 10 is also moved in the opening direction interlockingly with the middle door 4 together as shown in FIGS. As shown in the figure, the door side surfaces 3a, 4a, 5a of the three door bodies 3, 4, 5 are opened until they come into contact with the door contact 2a of the door side. In this open state, the three doors 3, 4 and 5 overlap in the front-rear direction, and the door opening M1 is secured.

  In order to set to overlap in this manner, the switching pivot shafts 90 of the front door 3 and the rear door 5 are respectively inserted into the door attachment holes 61 of the front and rear transmission bodies 60. Let

On the other hand, when it is desired to set the remaining portion L, the switching pivot shaft 90 of the rear door 5 is temporarily removed from the door mounting hole 61, and the switching pivot 90 is pulled as shown in FIG. The remaining setting attachment holes 62 are inserted and attached. As a result, as shown in FIG. 14 (B) and FIG. 3, the left side L is generated in the rear door 5 by an amount corresponding to the distance between the door mounting hole 61 and the left mounting hole 62. When the door is open, the opening M2 is secured. As a result, when the rear door 5 is provided with a handle, when the rear door 5 is opened, the user does not pinch a finger between the handle and the intermediate door 4.
Moreover, as shown to FIG. 2 (B), when the front side door 3 is provided with the handle etc., when the front side door 3 is opened, the door side of the front side door 3 and the middle door 4 is opened. The side portions 3a and 4a do not abut the door stop 2a. Therefore, the user does not pinch a finger between the side portions 3a and 4a and the door contact 2a.

  It should be noted that, contrary to the configuration described above, with the pivot shaft 90 of the rear door 5 inserted in the door attachment hole 61 of the rear transmission body 60, the transmission body of the front door 3 with the pivot shaft 90 If it is made to insert in the remaining attachment setting attachment hole 62, the left attachment L can be set to the front door 3.
