2. Description of the Related Art As a conventional interlocking door device, Japanese Patent Publication No. 57-3
No. 5349 “Interlocking hanging door” is available.
..A first suspension door provided at both ends with a door roller rolling a guide rail, and second suspension doors provided at both ends with a door roller rolling the guide rail similarly to the first suspension door The two suspension doors are arranged such that the door provided at one end of the first suspension door is located between the doors provided at both ends of the second suspension door, and the guide rail is provided on the second suspension door. An interlocking suspension door provided with a sub-guide rail that moves the suspension door by rolling the door roller of the first suspension door. And "Comparing the door wheels 8, 9 with the door wheels 13, 14, the diameter is determined so that the door wheels 13, 14 are slightly smaller." That is, the second door (outer door).
Is supported by one of the first doors (inner doors) via the auxiliary guide rail, and the door of the second door has a small diameter, so that either the right or left door is suspended from the rail. -ing

Another prior art is disclosed in Japanese Patent Application Laid-Open No. Hei 8-23.
No. 2543, “An interlocking door roller lock prevention device” is also available. As can be seen from the drawing, the outer door is supported in a balance shape with one roller of the inner door located below the movable rail as a fulcrum.

[0004]

One of the reasons why such a structure is adopted is that one of the doors must be operated so that the other door is also interlocked. For this purpose, a movable rail (sub guide rail) is required. Since the frictional force must always be maintained at the contact point with the roller located therebelow, by providing a slight gap between the right or left roller on the upper edge of the door to be operated and the fixed rail, The contact is continuously loaded. However, when the roller serving as a fulcrum shifts to the left or right of the center of gravity of the door in the opening and closing operation of the door, the door tilts to the right or to the left, causing rattling.

Therefore, in the present invention, since the left and right rollers of the door to be operated are always in contact with the fixed rail without reducing the frictional force between the movable rail and the roller in contact with the movable rail, the door is inclined left and right. An object of the present invention is to provide an interlocking door mounting device that does not rattle.

Description of the Related Art Conventionally, an interlocking door as this type of interlocking door apparatus is composed of a first door provided at both ends with a door roller rolling a guide rail attached to a house or the like, and a first door provided with the first door. Like the door, second suspension doors provided at both ends with a door roller rolling the guide rail were provided, and door rollers provided at one end of the first suspension door were provided at both ends of the second suspension door. A sub-guide rail that arranges both hanging doors so as to be located between the door cars and moves the hanging door by rolling the door car of the first hanging door, facing the guide rail on the second hanging door. An interlocking type suspension door provided with a door wheel 8, 9 and a door wheel 13, as shown in FIG. 4 or 5 of Japanese Patent Publication No. 57-35349.
Comparing the diameters of the door wheels 13, 14,
Each dimension is determined to be slightly smaller than 9, which is also described in the detailed description of the invention. That is, the second suspension door (outer door) is supported by one door of the first suspension door (inner door) via the auxiliary guide rail, and the left and right doors of the second suspension door have the same diameter. Is smaller than that of the first suspension door, so that either of the left and right door rollers is combined in a state of being lifted off the rail (balance state).

As another prior art, there is a "locking device for an interlocking door roller" described in Japanese Patent Application Laid-Open No. Hei 8-232543 which is a prior application of the present applicant. In this case, as can be seen from the drawing, the outer door is supported in a balance-like manner such that one of the outer doors is slightly raised with one roller of the inner door positioned below the movable rail as a fulcrum.

[0004]

The reason why the relation between the movable rail and the roller in each of the interlocking doors is a balance-like structure as described above is that when one door is opened and closed, the other door is opened and closed. The door to be operated (outer door) because the movable rail (sub guide rail) and the roller located below and in contact with it must always maintain a frictional force in order to work together. By providing a small gap between the right or left side roller opposite to the upper edge of the fixed rail and the fixed rail, a continuous load at the contact point is applied to the roller at the fulcrum contacting the contact point. . However, at the time of the opening and closing operation of the door, when the roller serving as the fulcrum shifts from the center of gravity of the outer door to the left or right in the above-described state, the door tilts slightly to the right or left due to a slight gap with the fixed rail. Upset, causing rattling.

Therefore, in the present invention, the left and right rollers of the outer door are always in contact with the fixed rail without loosening the frictional force between the movable rail and the roller supporting the movable rail in contact with the lower side. It is an object of the present invention to provide an interlocking door mounting device without rattling by preventing the outer door from tilting to the left and right and swinging in a state where the outer door is tilted.

[0006]

As means for solving the above problems, a roller at the upper end of a door is loosely fitted on a fixed rail provided on an upper edge of an opening of a building so as to be freely pulled and suspended in a pulling manner. In the interlocking door, wherein the movable rail provided at the upper end of the outer door is mounted on the roller of the inner door and linked to each other, the weight of the outer door is set in a state where the movable rail is mounted on the roller of the inner door. And a method of mounting the interlocking door, wherein the movable rail provided at the upper end of the outer door is elastically formed. For example, the movable rail is formed separately from the supporting portions of the rolling rollers provided on both sides of the movable rail so as to impart elasticity such that the mounting portion can easily expand and contract.
