Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) This invention relates to a folding door in which three or more panels are connected together.

(Prior art) Opening/closing the above-mentioned folding door is difficult.

If the number of sheets exceeds that number, operation becomes difficult.

(Problems to be Solved by the Invention) The present invention aims to eliminate the above-mentioned conventional problems and provide a folding door that can be easily opened and closed.

The configuration of the present invention is as follows.

(Means for Solving the Problems) The present invention takes the measures as described in the claims above, and its effects are as follows.

(Operation) When one door is opened and closed, other doors also open and close with a time lag. Therefore, starting is easier.

(Example) Below, drawings showing examples of the present application will be described. 1.1゛ indicates the opening of a wardrobe (or a vacant room such as a closet), 2.2゛ indicates the upper and middle frames, and 2゛ indicates the bottom side. Note that when the folding door 3 of the main body is installed in the opening 1a of the building as shown in FIG. 13, the lower stile 2a may be installed on the floor below. Reference numeral 3 indicates a folding door composed of a plurality of (three or more) doors 4 that are interconnected and arranged in parallel. 1st
In the figure, the first to sixth doors 4 are shown in order from right to left.
, but this may be 10 doors. The first and second doors (41 and 4□), the third and fourth doors (513 and 44)
) and the fifth and sixth doors (4, 4.) are each foldably connected by, for example, a hinge fitting 5 in FIG. 3. The moving body 6 is capable of lateral movement along a rail 7 provided along the upper part 2.

Reference numeral 8 indicates a suspension roller, which is attached to the movable body 6 via a mounting bracket 9. Reference numeral 10 indicates two rollers for steady rests arranged in parallel, which are attached to the movable body 6 via mounting fittings 11. I2 is a downward guide rail, and the 11th
The width is such that the moving body 6 shown in the figure does not wobble significantly in the direction of the arrow 13. Each door 4 adjacent to the movable body 6 is hinged to the movable body 6 so as to be bendable, for example, as shown in FIG. 3.

Next, the interlocking mechanisms 14 provided above each moving body 6 will be explained. This mechanism is comprised of connecting arms 15.18 whose bases are fixed to the doors on both sides and extend therefrom, and a lever 16.17 for power transmission interposed therebetween. In addition, there is a gap 19.2 between the arm and the lever as a means to delay the interlocking transmission.
0 is set.

In addition, 21 indicates a fixed plate fixed to the upper part of the moving body 6,
From this, four pins 22.23 are established, each pivoting a lever 16.17 and an arm 15.18. Reference numeral 24 indicates a pivot pin passing through the long holes 16' and 17° at each end of the lever, and reference numerals 25 and 26 indicate pins provided at the other end of the lever for standing in the gear. Reference numeral 27 denotes a tension spring provided between the rising portion 28 on the rear part of the board and the rising piece 29 on the door 4 side, which moves when the door is opened and closed to maintain its open state and closed state. In the middle, the fulcrum points 23 and 23 are respectively exceeded.

In the above configuration, the door 4 is moved from the opening closed state shown in FIG.
When a force is applied in the direction of arrow 30 to □, this door opens about 30 degrees and moves to position 4M shown by the two-dot chain line in FIG.
5, when the door 4M is further pushed in the direction of arrow 30, the levers 16 and 17 are pushed in the direction of arrow 31, and the third lever on the left
Start turning door 4 in the direction of arrow 32. In this way, the state shown in FIG. 3 is reached.

In this state, the fifth and sixth doors are not receiving any force and are not moving, the moving body 6 on the right end of FIG. 3 has moved largely to the left, and the second moving body 6 from the right is moving slightly to the left. I'm moving to. If the second door is further pushed in the direction of arrow 30, the relationship between the fourth door and the fifth door will eventually reach the operational relationship previously described with reference to FIG. In this way, the opening operation of the second door causes the third and fourth doors to operate with a time delay, which in turn causes the next door to open with a time delay, and in the end, as shown in Figure 4. The openings of the moving bodies 6 are closely arranged in an open state as shown in FIG. Next time you close the door, do the opposite of the above.
When you pull the second door in the direction of arrow 33, the doors close one after another and the second
It will be in the state shown in the figure. The above can be done with the second, third, and fourth three doors, and the same can be done even if the number of doors increases to 8 or 10.

(Effects of the Invention) As described above, in the present invention, when opening and closing multiple doors, there is a time difference and the inertia of the door being opened can be used to start the next door. This makes it possible to open the doors one after another with less force than starting the doors at the same time. Also, since you can open multiple doors one after the other, you can open multiple doors by yourself. The force in the direction of arrow 34 when opening is also small (light). It fits compactly as shown in Figure 4.
