<Description of Operation of Glide Slide Door Device 1>
Next, the operation of the glide slide door device 1 having the above-described configuration will be described in detail with reference to FIGS. 8 (a) to 8 (d). The operation of the glide slide door device 1 of this embodiment is as follows.
(1) When the child door 10 slides with respect to the parent door 20, the fully closed state (see FIG. 2A) changes to the intermediate open state (see FIG. 2B) (or from the intermediate open state). Until it is fully closed)
(2) When the child door 10 and the main door 20 in an overlapping state are glide, the intermediate open state (see FIG. 2B) is changed to the fully open state (see FIG. 2C) (or from the fully open state). Until the intermediate open state)
It is divided into.

<(1) Slide of child door 10>
First, in the fully closed state, as illustrated in FIG. 8A, the child door 10 is disposed at a position that does not substantially overlap with the parent door 20. In addition, the door hanger 40 which suspends the child door 10 is provided in the door-end side from the center of the width direction (arrow X direction) of the child door 10. The guide door 44 provided on the door hanger 40 is disposed in the linear guide rail 32, and the swinging door wheel 13 provided on the door hanger 40 is disposed in the inclined rail 33. The load support roller 46 is disposed on the linear motion rail 31.

  When the door engine 61 is driven, the toothed belt 66 is driven, and the door hanger 40 connected to the toothed belt 66 moves. As a result, the load support roller 46 and the guide door 44 provided on the door hanger 40 travel on the linear motion rail 31 and the linear motion guide rail 32, respectively, so that the door hanger 40 moves linearly in the direction of the arrow X1. At this time, since the swinging door pulley 13 travels on the straight portion SL of the inclined rail 33, the position of the swinging door pulley 13 does not change with respect to the rotation shaft 11 of the child door 10. For this reason, the child door 10 does not rotate. The child door 10 slides while the swinging door pulley 13 is traveling on the straight portion SL of the inclined rail 33. And the child door 10 and the parent door 20 will be in the state overlapped.

  At this time, the lock of the support arm 21 (the main door lock arm 22) by the lock mechanism 50 (the fourth crank 54) is released. The operation of the lock mechanism 50 will be described later.

  When there is no need to widen the frontage F (see FIG. 2), such as when there is a small amount of traffic, only the child door 10 described above may be slid.

<(2) Glide of the child door 10 and the parent door 20>
After the swinging door pulley 13 travels on the straight portion SL of the inclined rail 33, when it enters the inclined portion CL, the child door 10 and the parent door 20 glide. Even after the child door 10 and the main door 20 overlap, each of the load support roller 46 and the guide door 44 provided on the door hanger 40 travels on the linear motion rail 31 and the linear motion guide rail 32 without changing. The door hanger 40 moves linearly in the direction of the arrow X1. On the other hand, as shown in FIGS. 8 (b) and 8 (c), the swinging door pulley 13 travels on the inclined portion CL of the inclined rail 33, and therefore the swinging door pulley 13 with respect to the rotation shaft 11 of the child door 10. Swings. Along with this, the child door 10 rotates about the rotation shaft 11 in the direction of the arrow R5. As the child door 10 rotates, the main door 20 also rotates in the direction of arrow R6 about the rotation shaft 23 at the tip of the support arm 21.

  When the door hanger 40 further travels along the linear motion rail 31 and the linear motion guide rail 32, each of the main door 20 and the sub door 10 further rotates around the rotation shaft 23 and the rotation shaft 11. At this time, a force to bring out the child door 10 and the parent door 20 is generated, and the support arm 21 rotates in the direction of the arrow R7 to swing the tip end portion (rotating shaft 23). Thereby, as shown in FIG. 8D, the child door 10 and the parent door 20 rotated about 90 ° from the fully closed state are arranged along the wall surface W. As a result, a large frontage F is formed.

<Description of Operation of Lock Mechanism 50>
Next, the operation of the lock mechanism 50 that locks and unlocks the support arm 21 will be described.
First, when the door hanger 40 moves in the arrow X1 direction from the fully closed state, the lock mechanism abutment roller 49 provided on the door hanger 40 abuts on the third connecting rod 57 as shown in FIG. As a result, the third connecting rod 57 is pressed in the arrow X1 direction, and the third crank 53 and the fourth crank 54 swing in the arrow R2 direction.
