Description

[Detailed description of the invention] (Industrial application field) This invention is an interlocking type sliding door in which each door body opens and closes in conjunction with each other. This invention relates to a device in which adjacent door bodies are brought into close contact with each other when the door is placed in the state.

(Prior Art) Regardless of whether the door is manual or electric, in a sliding door that is interlocked via a linking member, the inner door body close to the door pocket is pressed into contact with the adjacent outer door body and is pushed into the door pocket. Then, when the sliding door stored in the door bag is pulled out, the adjacent inner door body is pulled out in conjunction with the connecting member, and finally each door body is mounted along the rail and the entire door body is pulled out. It becomes a closed state.

When storing a sliding door in the door compartment as described above, each door body is pushed in, so the door bodies move toward the door compartment while remaining in close contact with each other. However, when the sliding door is pulled out, the connecting member of the outer door body moves inward. Since parts of the door bodies are towed, the door bodies often do not come into close contact with each other.

(Problem to be solved by the invention) If the door bodies of a sliding door that have been pulled out from the door pocket and are in a fully closed state do not come into close contact with each other, there is a risk that wind and rain may enter through the gap, and it is also not aesthetically pleasing. There is a drawback that rattling occurs, and for this reason, it is troublesome to attach a device such as a lock to the sliding door.

(Means for Solving the Problems) This invention was made in order to eliminate the above-mentioned drawbacks of the conventional structure, namely, an elevated structure in which a door roller 5 is provided at the upper end and the door roller is connected to the rail 2 inside the door compartment. The outer end of the rod 3 faces the inner end of the end door body 9 connected to the elevated rod 3 by the connecting fitting 10, and the other end of the tension spring 17 has one end fixed inside the elevated rod 3. This is a close-closing device for an interlocking sliding door in which the elevated rod 3 is pressed against the end door body 9 by being fixed to the inner wall of the door compartment on the entrance/exit 1a side.

(Function) One end of the tension spring 17 is fixed to the elevated rod 3, and the other end of the tension spring 17 is fixed to the inner wall of the door pocket 1 on the entrance/exit 1a side, so that the elevated rod 3 is constantly directed toward the outside of the door pocket when the door is closed. Therefore, the end door body 9 located at the outer end of the elevated rod 3 is pushed outward by the elevated rod, and the door body 9 adjacent to the end door body is also pushed outward. Since they are interlocked, the side edges of each door body are in close contact when the sliding door is fully closed. To retract the sliding door from this state, the door body 9 can be pushed toward the door pocket 1 like a normal sliding door. That is, the elevated rod 3 that has been pressed against the end door body 9 moves toward the back of the door compartment as the door wheel 5 rolls along the guide portion 2a of the rail 2, and at this time the tension spring 17 is slightly expanded. do. Each door body 9 also moves sequentially to the inner part of the door pocket 1 along the rail 2 and its guide portion 2a, and finally each door body is stored in the door pocket in an overlapping manner. Then, by pulling out the outer door body 9 from this state, the inner door body 9 is interlocked and extended, and the elevated rod 3 is also interlocked with the end door body 9 via the interlocking fitting 10, so that the door pocket 1
It is pulled out from the deep part of the door and pressed against the end door body as described above.

(Example) An elevated rod 3 arranged parallel to the lower surface of the rail 2 inside the door pocket 1 has a guide groove 4 at the upper end, and a door roller 5 is provided protruding from the left and right ends of the guide groove, so that the door roller can be moved into the rail 2. are in contact with each other. Since the door roller 5 is attached to the shaft 7 via the pivot ring 6, it can also rotate in an oscillating manner.Therefore, the door roller 5 can be rotated along the left and right guide portions 2a formed by bending the rail 2. can be transposed. elevated rod 3
The outer end of the door body 9 is mounted between the rail 2 and the lower frame 8.
The inner end faces the inner end of the door body 9, and both are linked by a linking fitting 10. That is, the connecting metal fitting 10 consists of a connecting piece 10a whose one end is pivotally connected to the shaft 12 of the left side door wheel 11 of the door body 9, and a sliding metal 10b engaged with the guide groove 4 of the elevated rod 3, and the end of the connecting piece 10a is attached to the sliding metal 10b. Therefore, when the elevated rod 3 is pressed by the door body and moves from the rail 2 to the guide part 2a when the sliding door is retracted, the connecting piece 10a of the end door body 9 moves to the sliding metal 10b.
At the same time, the end door body 9 is overlapped with the elevated rod 3 because it moves along the guide groove 4 of the elevated rod. Each door body 9 is provided with a guide groove 14 at the upper end, similar to the elevated rod.
A door wheel 11 protruding from the left and right ends of this guide groove is attached to a shaft 12 via a pivot 13.
Since the other end of the connecting piece 15 with one end pivotally connected to the guide groove 14 is engaged with the sliding metal 16 that is engaged in the guide groove 14, when the end door body 9 is overlapped with the elevated rod 3, the end Since the connecting piece 15 of the door body adjacent to the sliding bar 16 moves along the guide groove 14, the door body is overlapped with the end door body, and in the same way, each door body moves to the guide part 2a and the entire sliding door is moved. are superimposed inside the door pocket 1.

Therefore, the other end of the tension spring 17, which has one end fixed to the shaft 7 inside the elevated rod 3 (on the left side in the figure), is connected to the entrance/exit 1.
It is fixed to a mounting bracket 18 that is fixed to the inner wall of the door compartment 1 on the side a. Therefore, the elevated rod 3 is located on the underside of the rail 2 and is constantly pulled outward, so the end door body 9 is attached to the elevated rod. 3. Receive pressure welding.

(Effect of the invention) The elevated rod 3 is constantly pulled elastically toward the outside of the door bag by the tension spring 17, but when the sliding door is retracted, the elevated rod 3, which is pressed by the door body 5, is affected by the action of the tension spring. It moves smoothly to the back of the door pocket along the guide portion 2a of the rail. When the stored sliding door is pulled out, the elevated rod 3 is moved to the end door body 9.
Since the sliding door is pressed elastically, when the sliding door is fully closed, the inner door body will press the outer door body one after another, so all the door bodies will be in close contact with each other and there will be no gaps. . Therefore, infiltration of wind and rain can be prevented, and since the door body is securely mounted along the rail 2, there is no need to attach a special device to prevent rattling.

As mentioned above, this invention is characterized by the fact that the elevated rod placed along the rail inside the door compartment is pressed against the end door body, so it has the practical advantage of being easily installed on existing interlocking sliding doors.
