That is, due to the action of the groove forming member 3 and the support plate 5, the sliding doors 2 are aligned in a plane in the fully closed position as shown in FIG. As it moves to the position just before closing,
The sliding door 2 that was operated to open moves to the other rear side,
As shown in Figure 4 C, the sliding door 2 is in the fully closed position.
are arranged in front and behind each other.

A pair of path switching members 8 are provided on the first member 3a so as to be swingable around a support shaft 9, so that the hanging member 4 is reliably moved in a predetermined direction, and
The second member 3b is provided with a linear or plate-shaped spring 10 bent at both ends so that the center portion protrudes into the groove, so as to stably hold the sliding door 2 in the fully closed position. The second member 3b and the spring 10 are configured to be pressed to a position immediately before being fully closed, and are further configured to generate a collision sound between the second member 3b and the spring 10 as the second member 3b and the spring 10 are opened and closed.

A large diameter notch portion 6a for inserting and removing the hanging member 4 is provided at each of the ends of the notch 6 of the first and second support plate portions 5a and 5b, and a large diameter notch portion 6a of the hanging member 4 is provided. The stopper 11 that prevents movement from the first
and the second members 3a and 3b, so that the sliding door 2 can be easily attached and detached. Further, the stopper 11 is configured to be stably held in the movement blocking position by fitting the convex portion 11a formed therein into a concave portion formed in the first or second support plate portions 3a, 3b. be.

As shown in FIGS. 5 and 6, a guide mechanism 13 is provided at the bottom of the storage box 1, located at the left and right center of the opening and closing opening, as shown in FIGS. 5 and 6, to prevent the sliding door 2 from swinging back and forth. , the sliding door 2 is configured to smoothly move between a fully closed position and a position immediately before fully closed.

That is, a pair of left and right guides 16 are attached to the lid body 14 provided flush with the inner bottom surface of the storage box 1 so as to be able to swing freely around a support shaft 15 protruding from the bottom surface of the lid body 14. A portion 16a that engages with the formed guide groove 17 is made to protrude upward from a notch in the lid body 14, and the guide 16 is configured to swing as the sliding door 2 moves from a fully closed position to a position immediately before fully closed. In addition, the guide 16 is configured to be constantly engaged with the guide groove 17. In addition, a linear or plate-shaped spring 18 whose one end is locked to the lid 14 acts on a spring receiving portion 16b connected to the guide to stably hold the guide 16 at each of the swinging end positions. As a result, the sliding door 2 can be reliably fixed in the fully closed position, and the guide 16 can be prevented from unexpectedly swinging when the sliding door 2 is closed. Further, the engaging portion 16a of the guide 16 is formed into an elongated shape such as a rectangle or an ellipse when viewed from above, and most of the guide groove 17 is formed to have a width I ₁ close to the width l ₁ of the engaging portion 16a. ,
Of the ends of the guide groove 17, the side 17a with which the guide 16 engages in the fully closed state is formed into a substantially circular shape with a diameter _L2 close to the longitudinal dimension _L2 of the engaging portion 16a, so that the sliding door 2 is fully closed. When the sliding door 2 is in the position, the longitudinal direction of the engaging portion 16a intersects with the longitudinal direction of the guide groove 17, and when the sliding door 2 is in the position immediately before fully closing, the engaging portion 16a
The direction of the engaging portion 16a is changed as the guide 16 swings so that the longitudinal direction of the engaging portion 16a is directed toward the longitudinal direction of the guide groove 17. The external force for the swing is made to act efficiently.

The sliding door device according to the present invention can be applied to various uses such as building doors and partitions, and the sliding door 2 may be configured to be flush with a fixed wall and overlap.

Further, the direction of movement of the sliding door 2 between the fully closed position and the immediately before fully closed position can be freely changed in design, and in short, it is sufficient if the sliding door 2 is configured to move in a direction perpendicular to the door surface.

Further, the specific structures of the hanging member 4 and the stopper 11 can be changed freely, and furthermore, the hanging support structure of the sliding door 2 can also be changed in various ways.

In summary, in the above-mentioned sliding door device, the present invention provides a large-diameter notch 6a for inserting and removing the hanging member 4 connected to the sliding door 2, which is formed on the support plate 5 for the hanging member 4. A stopper 1 is formed to communicate with a notch 6 for guiding the lower member and prevents the hanging member 4 from moving toward the large diameter notch 6a.
