[Operation] In the sliding door device configured as described above, when the sliding door is opened from the closed state of FIG. 1, the drive member 3 is moved in the door opening direction (left side of the drawing). Since the connecting member 4 fixed to the first slide door 2A is connected to the connecting rod 31 so as to be relatively movable only in the axial direction, the slide door 2A moves integrally with the drive member 3 in the same direction. The guide rail 1A is guided by the bent tip end portion of the first guide rail 1A to be moved rearward orthogonal to the moving direction. After passing through the bent portion, it is guided by the straight rail general portion and moves in the opening direction.

While the drive member 3 is moving in the opening direction, the engaging member 5 fixed to the second slide door 2B engages with the connecting rod 31. Since the engaging member 5 engages with the connecting rod 31 so as to be relatively movable only in the axial direction, the second slide door 2B starts moving in the same direction as the driving member 3 in the same direction, and The second guide rail 1B is guided by the bent front end of the guide rail 1B and is moved rearward orthogonal to the moving direction. After passing through the bent portion, the guide rail 1B is guided by the straight rail general portion and moved in the opening direction.

When closing the sliding door, the drive member 3 is moved in the closing direction. First and second sliding doors 2A,
2B both move integrally with the drive member 3, but during the movement, the second slide door 2B is guided by the bent tip end portion of the second guide rail 1B to start moving forward, Reach the closed position. When reaching the closed position, the engagement between the engagement member 5 and the connecting rod 31 is released, and the second slide door 2B stops at the closed position.

On the other hand, the first slide door 2A continues to move together with the driving member 3, reaches the bent front end of the first guide rail 1A, starts moving forward, and reaches the stop position. In this stop position, the first slide door 2A and the second slide door 2B are located flush and adjacent to each other.

In this way, the single drive member moves the slide doors to the left and right, opens and closes them, and moves the slide doors back and forth near the closed ends to place them in a flush closed state.

[Embodiment] FIG. 1 shows a schematic perspective view of an interlocking slide door device in which two slide doors are closed. In the figure, slide doors 2A and 2B are adjacent to each other flush with each other and are located at left and right positions, and are supported by guide rails 1A and 1B, respectively, by a structure described later. The above guide rails 1A and 1B are a pair of rail members.
11 and 12, these rail members 11 and 12 extend in the left and right directions in parallel behind the slide doors 2A and 2B, and the respective right end portions, which are tip portions, are gently bent substantially parallel to the front, The upper ends of the slide doors 2A and 2B extend to the left and right positions.

The details of the door support structure will be described with reference to FIG.
11 has a C-shaped cross section with an open bottom center,
It is fixed to the underside of. A bracket 14 is provided, which includes a pair of guide rollers 13 provided at the front and rear positions of the upper end,
It is positioned inside the rail member 11. The bracket 14 is provided with a hanging metal fitting 15 extending downward.
The lower end of 15 is a bearing member 22 provided on the upper surface of the slide door 2A.
It is connected to a shaft body 21 which is rotatably supported by. In addition,
The upper surface of the door is located close to the lower surface of the hanging wall R1.

Thus, the inside of each of the rail members 11 and 12 is guided by the guide roller 13
As the rail members 11 and 12 move, the slide doors 2A and 2B move to the left as well as to the rear at the right ends of the rail members 11 and 12, and the front of the door is maintained in a front-facing posture during this movement. To be done.

In FIG. 1, guide plates 6A and 6B are provided on the floor F facing the guide rails 1A and 1B, and the guide plates 6A and 6B are provided at the center of the lower end surfaces of the slide doors 2A and 2B. The provided roller 23 abuts (FIG. 3) to prevent shaking when the sliding door is moved.

A linear motor rail 7 is provided linearly in the left-right direction on the lower surface of the ceiling behind the guide rails 1A and 1B, and a drive runner 3 is provided in the linear motor rail 7 so as to be horizontally moved by the linear motor rail 7. A connecting rod 31 projects forward from the drive runner 3 in a direction orthogonal to the moving direction of the drive runner 3. The connecting member 4 provided at the right end of the upper surface of the slide door 2A is connected to the tip of the connecting rod 31.

The connecting member 4 is a cylinder that holds the outer periphery of the connecting rod 31, and a ball slide bearing is built in the cylinder so that the connecting member 4 can move only in the axial direction of the connecting rod 31.

A locking member 5 is provided at the right end of the upper surface of the slide door 2B. The locking member 5 is a substantially U-shaped plate body as shown in FIGS. 4 and 6, and the lower end center thereof is rotatably supported by a bracket 24 provided on the door. The locking member 5 has horizontal and vertical stopper surfaces 5 at right-angled notches at the lower end of the left side surface.
a and 5c are formed, and the stopper surface 5 is
b is formed, and the locking member 5 has a standing posture in which the stopper surface 5a abuts the end surface of the bracket 24, and the stopper surface.
5b is rotated between the laterally inclined postures of the chain line shown in the figure, which are in contact with the end face of the bracket 24.

A stopper plate 8 having an inverted V shape (FIG. 5) is provided below the locking member 5 so as to be orthogonal thereto, and the stopper plate 8 is rotatably attached to the bracket 24 at the lower end bent portion. It is supported. The stopper plate 8 has long legs 81 and short legs 82.
Since it is heavier than the above, it normally falls toward the long leg portion 81 side as shown in the figure, and in this state, the tip of the short leg portion 82 abuts on the stopper surface 5c of the locking member 5 to prevent it from falling sideways. There is.

When the sliding door 2B reaches the closed position close to the hanging wall R1, the long legs 81 of the stopper plate come into contact with the inner surface of the hanging wall R1 (chain line in FIG. 5), and the stopper plate 8 is rotated to the upright position. To be In this state, the short leg portion 82 is disengaged from the stopper surface 5c, and the locking member 5 can be laid sideways (FIG. 7).

The locking member 5 is tilted to the left in FIG.
That is, the connecting rod 31 moving in the door closing direction is received in the U-shaped recess 51, and the connecting rod 31 moving in the right door opening direction is disengaged from the recess 51. Then, in the standing posture, the connecting rod 31 is set in the recess.
It is held inside 51 and locked. Since the width of the concave floor 51 is larger than the diameter of the connecting rod 31, the engaging member 5 is relatively movable in the axial direction of the connecting rod in the engaged state.

The operation of the interlocking slide device having the above structure will be described below with reference to FIG.

In the door closed state, the slide doors 2A and 2B are flush and adjacent to each other immediately below the hanging wall R1, and the drive runner 3 is at the right end of the linear motor rail 7 (Fig. 8 (1)). In this state, the locking member provided on the slide door 2B is lying sideways due to the stopper plate abutting against the hanging wall and in the standing posture.

When the door is opened, the drive runner 3 moves leftward.
Along with this, the slide door 2A in which the connecting member 4 is connected to the connecting rod 31 starts to move to the left and also moves rearward along the tip of the guide rail 1A (Fig. 8 (2)). . This backward movement is possible by the relative movement of the connecting member 4 in the axial direction of the connecting rod 31.

When the drive runner 3 further moves to the left, the connecting rod 31
Engages in the locking member 5 in the sideways state and rotates it to the upright posture, and in this state also moves the slide door 2B to the left. The sliding door 2B moves leftward and rearward along the tip of the guide rail 1B (FIG. 8 (3)). This rearward movement is possible by the relative movement of the engaging member 5 in the axial direction of the connecting rod 31.

At this time, as the sliding door 2B moves away from the hanging wall R1, the stopper plate 8 (FIG. 5) is moved by its own weight to the long leg portion.
It falls to the 81 side and prevents the engaging member 5 from falling sideways.

In this way, the slide doors 2A and 2B are interlocked with each other and move to the open position at the left end, which is lowered rearward.

To close the slide door, move the drive runner 3 to the right, and both slide doors 2A and 2B move in the same direction along the guide rails 1A and 1B.
2B reaches the bent tip of guide rail 1B on the way and starts moving forward. When the sliding door 2B reaches the closed position directly below the hanging wall R1, the stopper plate 8 contacts the hanging wall R1 and rotates, allowing the engaging member 5 to fall sideways.

When the drive runner 3 further moves to the right, the engaging member 5 falls sideways to release the engagement with the connecting member 31, thereby stopping the movement of the slide door 2B. The slide door 2A further moves to the right, reaches the tip of the guide rail 1A, and moves forward. When the drive runner 3 reaches the right end, the slide door 2A reaches the closed position immediately below the hanging wall R1 and stops flush with the slide door 2B.

In the above embodiment, the case where the number of sliding doors is two has been described, but if a plurality of doors having the same structure as the sliding door 2B are provided, it is possible to similarly open and close three or more sliding doors. is there.

[Effects of the Invention] As described above, according to the interlocking slide door device of the present invention,
The left and right movements and the forward and backward movements of a plurality of slide doors can be performed by a single driving member, and the structure is simple and the cost is low. Further, according to the present invention, since the front doors of the sliding doors are flush with each other and are adjacent to each other at the door closed position, the sliding doors have a good appearance and can be suitably used for partitioning the indoor space.
