Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-draw hanger door installed in a large opening.

In general, wide openings in factories etc.
Multiple door panels are hung symmetrically from a guide frame provided above the opening, and a multi-draw hanger door is provided that allows the door panels to be drawn left and right and stored in an overlapping manner to open and close the opening. That's what I do. However, in conventional hanger doors of this type, drive chains attached to multiple door panels are linked to a single electric opening/closing machine, so when opening a closed opening, the left side of the opening must be opened. The door panel that opens and closes the half part and the door panel that opens and closes the right half move at the same time and open symmetrically, so even when there is no need to open it so wide, the opening is always fully open, and the inside of the room is The drawback was that the loss of energy due to air conditioning, etc. was enormous. Therefore, there are devices that are equipped with a separate stop limit switch to stop the opening/closing machine before it is fully opened, but in this case, the opening position is limited to the vicinity of the center of the opening. If it is necessary to enter the room from another location, there is still the inconvenience that the entire opening must be left open as shown in FIG. 2C.

The present invention was devised in view of the above-mentioned circumstances, and includes a plurality of door panels that are interlocked and connected to open and close in a draw pattern for each pair of door panels corresponding to the left and right, and the interlockingly connected door panels are By connecting each door panel to a separate opening/closing device and configuring the building opening to be openable/closable for each corresponding door panel, multiple door panels can be drawn to the left and right at the same time and the opening can be fully opened quickly. If necessary, the opening can be opened narrowly to reduce energy loss due to indoor air conditioning as much as possible, and even when vehicles enter from other than the central area, To provide a multi-draw hanger door which can freely open only a desired position without opening the entire opening.

To explain the configuration of the present invention with reference to an embodiment shown in the drawings, 1, 2, 3, and 4 are openings 5 of a building.
Among the door panels 1, 2, 3, and 4, the door panels 1 and 2 that open and close the right half of the opening 5 are installed in parallel above the right half of the opening 5. The door panels 3 and 4 which open and close the left half are suspended from the guide rails 6 and 7 via hanger rollers 8 and 9, respectively. 11 via hanger rollers 12 and 13, respectively, so that the door panels 1 and 2 and the door panels 3 and 4 can be separated left and right and stored in an overlapping manner.

Both ends of a drive chain 16, which is suspended between a sprocket 14 provided on the door end side of the door panel 1 and a sprocket 15 provided on the storage side of the door panel 1, are fixed to the door panel 1. Parallel to the drive chain 16, both ends of a drive chain 19 are mounted and fixed around a sprocket 17 provided on the door edge side and a sprocket 18 provided on the storage side.

Moreover, the door panels 3 and 4 are also the above-mentioned door panels 1,
It is configured in the same way as 2. That is, door panel 3
Both ends of a drive chain 22, which is suspended between a sprocket 20 provided on the door end side and a sprocket 21 provided on the storage side, are attached and fixed to the door panel 4, and a sprocket 23 provided on the door end side Both ends of a drive chain 25, which is suspended from a sprocket 24 provided on the storage side, are fixedly attached.

26 is a drive chain 1 fixed to the door panel 1
6 and a drive chain 25 fixed to the corresponding door panel 4, the rotating shaft 27 of the sprocket 14 and the sprocket 23
It is composed of a pair of gears 29 and 30 that are fixed to a rotating shaft 28 of the engine and mesh with each other.
is designed to rotate in the opposite direction. 31
The drive chain 19 fixed to the door panel 2 corresponds to the drive chain 2 fixed to the door panel 3.
This is a reversing device that interlocks and connects the gears 2 and 2, and as described above, a pair of gears 3 fixed to the rotation shaft 32 of the sprocket 17 and the rotation shaft 33 of the sprocket 20.
The drive chain 19 and the drive chain 22 rotate in opposite directions.

And the storage side sprocket 1 of the drive chain 16
5 is connected to a single electric switch 36, while the storage side sprocket 18 of the drive chain 19
are connected to a single electric opening/closing machine 37 provided separately, and by opening/closing operations of the opening/closing machines 36, 37, the door panels 1, 4 corresponding to the left and right sides of the opening 5 and the other corresponding door panels 2, 3 are connected. are designed to open and close separately. 38 are door panels 1, 2, 3,
A guide rod 39 provided at the bottom of 4 is a lower guide rail with a concave cross section.

In this embodiment, a door panel having four panels is shown, but the door panel is not limited to this, and it goes without saying that four or more panels may be used.

In the above configuration, as shown in FIG. 2A, if the opening/closing devices 36 and 37 are simultaneously opened from the closed state of the opening 5 by a push button or a sensor (not shown), the door panels 1, 2, 3 ,4
are separated into left and right sides, and the opening 5 can be fully opened to allow large vehicles such as a to enter and exit easily (FIG. 2F). Note that if the rotational speed of the opening/closing machine 37 is twice that of the other opening/closing machines 36, the door panels 2, 3 on the center side will open twice as fast as the other door panels 1, 4, and the door panels 1, 2 will open at twice the speed of the other door panels 1, 4. , 3, and 4 are simultaneously accommodated in a superimposed manner, and the opening 5 can be quickly fully opened. In addition, when it is not necessary to fully open the opening 5 in order to allow only the small vehicle b to enter or exit, if the opening/closing machine 37 is stopped in the middle of opening, only the vicinity of the center of the opening 5 can be narrowly opened. Yes (Figure 2B). Alternatively, only the opening/closing device 37 can be operated to fully open only the door panels 2 and 3 located near the center, as shown in FIG. 2D. When it is necessary to enter or exit a small vehicle B or the like from a position other than the central area, by operating only one opening/closing machine 36, as shown in FIG. Since only the opening 5 can be opened, small vehicles etc. can freely enter and exit the room without having to fully open the opening 5 as in the conventional case, and energy loss due to air conditioning etc. can be reduced as much as possible. . Then, by operating the opening/closing devices 37 and 36, the opening 5 can be quickly closed.

In addition, door panels 1 and 4 and door panels 2 and 3
Since the doors are opened and closed separately by separate opening/closing machines, it is extremely convenient that the door panels 2 and 3 located near the center and the door panels 1 and 4 located on both sides can be formed to have different sizes.

In short, the present invention provides a hanger door in which a plurality of door panels are arranged symmetrically in an opening of a building, and the plurality of door panels are separated left and right and stored in an overlapping manner. A pair of door panels corresponding to the left and right sides are interlocked and connected to open and close in a drawn pattern, and each of the interlocked and connected door panels is connected to a separate opening/closing device to open and close the building opening for each corresponding door panel. Although it is possible to completely open the opening quickly by separating multiple door panels to the left and right, it is not possible to open the center of the opening narrowly if necessary, and it is not possible to open the opening narrowly if necessary. When you want to enter or exit from a position other than near the center, you can open only the door panels corresponding to the left and right of the desired position, which is extremely effective, as it can reduce energy loss due to air conditioning, etc. as much as possible. This has practical effects.
