Abstract

PROBLEM TO BE SOLVED: To provide a folding door which is excellent in fire protecting performance, sound insulating properties, water-tightness and air-tightness. SOLUTION: According to the folding door, a case 21 is fixed to the interior of a lower edge of a large door 120, and a slider 30 is housed in a slider housing space 24 of the case 21 in a horizontally movable but vertically immovable manner. Then, a sealing member 40 is housed in a sealing member housing space 25 of the case 21 in a horizontally immovable but vertically movable manner. The slider 30 includes a first magnet 32 and a third magnet 33, while the sealing member 40 includes a fourth magnet 42 and a sealing material 43. When the folding door is fully closed, both the first magnets 32 of a small door 110 and the large door 120 are attracted to each other, and the sealing member 40 is downward squeezed out due to a repellent force of the third magnet 33 and the fourth magnet 42. When the folding door is opened, an attractive force between both the first magnets 32 becomes weak, whereas the slider 30 moves in a direction that separates from the small door 110 due to the repellent force between the third magnet 33 and the fourth magnet 42, and thereafter the sealing member 40 is raised due to the attractive force between the third magnet 33 and the fourth magnet 42.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing device for sealing a gap above and below a door.

[0002]

2. Description of the Related Art Conventionally, for sliding doors and hinged doors, fire prevention,
In order to improve sound insulation, water and airtight performance, some devices were devised such as using springs to eliminate the gap between the top and bottom of the door.
Regarding the folding door, the gap between the top and bottom of the door was considered to be necessary for its function, and there was no particular requirement for fire prevention performance, sound insulation performance, and water / airtightness performance.

[0003] Nevertheless, in the case of a general folding door having two or more sheets of the same size, a door stop is attached from the beginning in order to eliminate the gap between the upper and lower parts. Can be satisfied. However, in this case, since a floor-like projection is required on the floor, there is a problem that the floor is stepped and cannot be flattened.

[0004]

For this reason, when it is desirable to have a step on the floor, such as in a bathroom, or in a storage case,
Generally, the above structure is not adopted unless there is no problem even if there is a step on the floor.

[0005] Further, with respect to a folding door having two or more sheets of different dimensions, such as is often used for the entrance of a telephone booth, the doors are perpendicular to the rail because the two doors are of different dimensions. Because of the intersection, achieving the above performance was considered impossible.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide fire prevention, sound insulation, and water / airtight performance without a projection or a step on a floor or a door frame. It is an object of the present invention to provide a door sealing device.

Thereby, fire prevention, sound insulation, and water / airtightness performance between the edge of the door and the surface to be sealed are improved.

When the door is opened, the slider moves from the initial position by the opening operation of the door.
The attraction force between the magnet and the fourth magnet urges the seal member in a direction approaching the slider. As a result, the seal member moves in a direction approaching the slider and separates from the surface to be sealed. Then, the opening operation is continued in a state where the seal member is separated from the surface to be sealed.

A second aspect of the present invention is characterized in that, in the first aspect of the present invention, a plurality of sets of the third magnet and the fourth magnet arranged to face each other are provided.

Is to be sealed. The sealing device 20 for sealing between the folding door 100 and the upper rail 220 is also a folding door 1.
Since the seal device 20 for sealing between the lower rail 230 and the lower rail 230 has exactly the same configuration and the same operation, the sealing device 20 for sealing between the lower rail 230 and the lower rail 230 will be described below. Description of the sealing device 20 that seals the gap with the seal 220 will be omitted.

FIG. 5 is a longitudinal sectional view of the sealing device 20 provided between the lower edge of the small door 110 and the large door 120 and the lower rail 230, FIG. 6 is a transverse sectional view thereof, and FIG. FIG. 7B is an enlarged vertical sectional view of the sealing device at the connecting portion between the small door 110 and the large door 120, and FIG. 7B is a sectional view taken along line II of FIG. 7A. A case 21 extending in the horizontal direction along the width direction is fixed to the room inside the lower edge of the large door 120. Case 21
The lower part facing the lower beam 230 is an opening 22 that opens over the entire length thereof, and the upper side than the opening 22 is a storage space. This storage space is case 21
Are divided into upper and lower two parts by a pair of ridges 23, 23 protruding from the inner surface, and the upper side is a slider storage space 24 and the lower side is a seal member storage space 25.
Also, a pair of ridges 26,

A slider 30 is provided in the slider storage space 24.
Are movably inserted in the width direction of the large door 120. The slider 30 includes a frame 31 made of an aluminum sash having a U-shaped cross section with an open lower side, a first magnet 32 fixed to an end of the frame 31 on the small door 110 side, and FIGS. 5 and 6. And three fixed third magnets 33 arranged at equal intervals from the position slightly away from the first magnet 32 to the vicinity of the other end, and have a length slightly shorter than the width of the large door 120. Is formed.

The first magnet 32 changes the direction of the line of magnetic force to the large door 12.
0, and in this embodiment, the small door 11
The side closer to 0 is the S pole, and the side farther is the N pole. The case 21 also has the small door 110 side opened, and the first
The magnet 32 has the S pole side facing this opening. The third magnets 33 also have the magnetic field lines oriented in the width direction of the large door 120, and in this embodiment, all the third magnets 33 are
The side closer to 10 is the S pole, and the side farther away is the N pole.

The slider 30 is immovable in the vertical direction by interposing the frame 31 between the ridges 23, 23 of the case 21 and the ridges 26, 26. It is mounted so that it can move only in the direction. Further, the lower ends of the third magnets 33 are connected to the ridges 23, 23.
It protrudes into the opening between.

On the other hand, the seal member 40 is inserted into the seal member storage space 25 so as to be movable in the vertical direction (that is, the direction in which the seal member approaches and separates from the slider 30) and is immovable in the width direction of the large door 120. I have. The seal member 40 includes a frame 41 made of an aluminum sash having a U-shaped cross section with an open lower side, three fourth magnets 42 arranged and fixed at predetermined intervals on the upper half side of the frame 41, 4 magnets 4

0 and a sealing material 43 having a length substantially the same as the width. The sealing material 43 is formed by coating a surface of a metal frame (not shown) such as an aluminum sash with a fireproof rubber.

The fourth magnet 42 adjusts the direction of the line of magnetic force to the large door 12.
In this embodiment, all the fourth magnets 42 have S poles on the side closer to the small door 110 and N poles on the far side. Each of the fourth magnets 42 is disposed at a position facing the third magnet 33 when the slider 30 is positioned close to the small door 110, and accordingly,
At that time, as shown in FIG.
Since the magnets 42 have the same poles facing each other, a repulsive force acts between the magnets 33 and 34. On the other hand, when the slider 30 moves in the direction away from the small door 110, the S pole of the third magnet 33 is substantially opposed to the N pole of the fourth magnet 42 as shown in FIG. , 4
An attraction force acts between the two, and the attraction force causes the seal member 40 to move upward.

The sealing member 40 is connected to the frame 41
The lower end of the case 21 is locked to the ridges 27, 27 which are bent inward at the lower end of the case 21 so as not to come off the case 21. Also, the sealing member 40
When it is magnetically attached to the third magnet 33 and rises, FIG.
As shown in FIG. 7, the seal member 43 is stored in the seal member storage space 25.

The inside of the lower edge of the small door 110 inside the room has the same structure as the large door 120 described above. In addition, about the small door 110, the same code | symbol is attached | subjected to the same aspect as the large door 120, and description is abbreviate | omitted.

Next, the operation of the sealing device 20 in the folding door 100 will be described. When the folding door 100 is fully closed (state A in FIG. 3), the slider 30 of the large door 120 is positioned closest to the small door 110 as shown in FIG. The slider 30 is located closest to the large door 120. This is the slider 3 of the large door 120
Since the S pole of the first magnet 32 at 0 and the N pole of the first magnet 32 at the small door 110 are very close to face each other, the first magnets 32 and 32 attract each other and the slider 30 of the large door 120 is small. This is because the slider 30 of the small door 110 is moved to the large door 120 side by moving to the door 110 side.
Hereinafter, the position of the slider 30 at this time is referred to as an initial position.
At this time, the slider 30 in the large door 120 is
Since the third magnet 33 and the fourth magnet 42 of the sealing member 40 have the same poles and face each other, a repulsive force is generated between the third magnet 33 and the fourth magnet 42. 40 is urged in a direction away from the slider 30. As a result, the sealing member 40 is pushed down,
The sealing material 43 projects from the opening 22 of the case 21 and is pressed against the lower rail 230 of the door frame 200. FIG. 10 is a schematic perspective view of a main part of the large door 120 at this time. The same applies to the small door 110, and the sealing material 43 of the small door 110 is
30.

Therefore, the small door 110 and the large door 120
Since the space between the lower edge and the lower rail 230 is shielded by the seal member 43, the sound insulation performance and the water / airtightness performance are significantly improved. In addition, since the sealing material 43 is made of fire-resistant rubber, the fire prevention performance is also improved. In this case, in order to further enhance the sound insulation performance, the water / airtightness performance, and the fire prevention performance, the Orido 10
When the seal member 43 is brought into contact with the lower rail 230 by fully closing 0, the lower edge of the frame 41 of the seal member 40 is
It is preferable to set the dimensions so as to abut the one ridge 26.

Next, when the folding door 100 is opened from the fully closed state, the small door 110 and the large door 120 are connected to the hinge 2 as described above.
(See FIG. 3).
8, the end plate 111 of the small door 110 on the side of the large door 120 and the end plate 121 of the large door 120 on the side of the small door 110 are separated from each other. as a result,
The S pole of the first magnet 32 in the slider 30 of the large door 120 and the N pole of the first magnet 32 in the slider 30 of the small door 110
Since the poles are separated from each other, the attractive force of the first magnets 32 is reduced. On the other hand, before the opening operation, the third magnet 33 and the fourth magnet 42 of the large door 120 have the same poles facing each other and a repulsive force is acting thereon. Due to the repulsive force generated between the magnet 33 and the fourth magnet 42, the slider 30 is instantaneously moved in the slider housing space 24 in a direction away from the small door 110.

Then, the third magnet 3 of the large door 120 is
Since the S pole of No. 3 approaches the N pole of the fourth magnet 42, an attractive force is generated between the third magnet 33 and the fourth magnet 42, whereby the seal member 40 is instantly lifted. In addition,
In this embodiment, since three sets of magnets including the third magnet 33 and the fourth magnet 42 are provided in the width direction of the large door 120 and provided, the force for lifting the sealing member 40 can be increased, and the sealing force can be increased. The member 40 can be reliably raised while being held in a horizontal posture. FIG. 11 shows the large door 12 at this time.
FIG. 2 is a schematic perspective view of a main part of No. 0. The same applies to the small door 110. The slider 30 of the small door 110 moves in the slider storage space 24 in the direction away from the large door 120, and the seal member 40 is instantly lifted.

When the folding door 100 is in the state indicated by C in FIG. 3, as shown in FIG. 9, the S pole of the third magnet 33 and the N pole of the fourth magnet 42 in the large door 120 are magnetically attached.
The seal member 40 is held by the slider 30 by this magnetic force, and is stored in the seal member storage space 25. FIG.
Is a schematic perspective view of a main part of the large door 120 at this time.

When the sealing member 40 is lifted, the sealing member 43 is naturally moved to the lower rail 230 of the door frame 200.
Therefore, during the subsequent opening operation of the folding door 100, the sealing material 43 does not drag the lower rail 230, so that the opening operation is performed smoothly without increasing the resistance during the opening operation, and The material 43 is also prevented from being damaged.

On the other hand, when closing the opened folding door 100, the large door 1 is not closed until the folding door 100 is almost completely closed.
The third magnet 33 and the fourth magnet 42 of 20 are magnetically attached, and the seal member 40 is stored in the seal member storage space 25 in a lifted state. When the folding door 100 approaches the fully closed state, the end plate 121 of the large door 120 and the end plate 111 of the small door 110 approach each other.
Between the third magnet 33 of the large door 120 and the fourth magnet 33 and the first magnet 32 of the small door 110.
When the magnetic force is larger than the magnetic force of the magnet 42, the slider 30 of the large door 120 is attracted to the small door 110, and the slider 3
0 returns to the initial position. Then, since the third magnet 33 and the fourth magnet 42 of the large door 120 have the same poles facing each other, a repulsive force is generated between the two magnets 33 and 34, and the seal member 40 is separated from the slider 30 and instantaneously. , And the sealing material 43 is pressed against the lower rail 230 of the door frame 200. As a result, the entire area between the lower edge of the large door 120 and the lower rail 230 is instantaneously sealed. The same applies to the small door 110, in which the slider 30 of the small door 110 moves to the large door 120 side and returns to the initial position, and the seal member 40 descends so that the seal member 43 is pressed against the lower rail 230.

As described above, according to the sealing device 20, sound insulation performance, water / airtightness performance, fire protection and the like, which have been difficult to provide to folding doors, which have been used up to now, because of their small rotation trajectory, are very useful. It is possible to provide performance. Further, since the sealing member 40 is moved up and down by the repulsive force and the attracting force of the magnets generated between the third magnet 33 and the fourth magnet 42, the operation of the sealing member 40 is reliable and the sealing device 20 can be simplified. Structure.

In order to operate the sealing device 20 as described above, the relative positional relationship between the third magnet 33 and the fourth magnet 42 when the slide member 30 is at the initial position is very important. . That is, in the sealing device 20, when the folding door 100 is opened, the third magnet 3 of the large door 120 is opened.
The seal member 40 cannot be lifted unless the slider 30 is moved away from the small door 110 by the repulsive force of the third and fourth magnets 42. However, the slide member 30 is located at the initial position. If the relative positions of the third magnet 33 and the fourth magnet 42 are out of a predetermined positional relationship when the slider 30 is open, the slider 30 is moved to the small door 11 during the opening operation.
This is because it cannot be moved in a direction away from zero.

This will be described with reference to FIGS. 13 to 15 show a state in which the slider 30 is located at the initial position. FIG.
Shows a case where the third magnet 33 is located farther from the small door 110 than the fourth magnet 42 when the slider 30 is located at the initial position. When the third magnet 33 and the fourth magnet 42 are in such a relative positional relationship, when the attraction force of the first magnet 32 is reduced, the slider 30 is repelled by the repulsive force between the same poles of the third magnet 33 and the fourth magnet 42. Is definitely moved away from the small door 110.

However, as shown in FIG. 14 or FIG. 15, when the slider 30 is at the initial position, the third
When the magnet 33 is located closer to the small door 110 than the fourth magnet 42, when the attracting force of the first magnet 32 is weakened, the same polarity of the third magnet 33 and the The repulsive force acts to move the slider 30 in a direction approaching the small door 110. However, since the slider 30 is restricted from moving in the direction approaching the small door 110 from the initial position, it is not possible to generate an attractive force between the third magnet 33 and the fourth magnet 42, As a result, the seal member 40 cannot be lifted.

Therefore, in this sealing device 20,
By adjusting the initial position of the slider 30, the third magnet 33 and the fourth
An initial position adjusting means 50 is provided so that the relative positional relationship between the magnets 42 can be adjusted. The initial position adjusting means 50 will be described with reference to FIGS.

A pair of brackets 51 and 52 are attached to the end plate 121 of the large door 120 on the side of the small door 110 by a countersunk screw 53 at a position corresponding to the upper side of the slider 30. One of the brackets 51 is immovably fixed to the end plate 121 and the other bracket 52 is

At the tip of the sliding piece 51a of the bracket 51, a locking piece 51b is formed by bending downward, and at the end of the sliding piece 52a of the bracket 52, a vertical piece 52c is formed by bending downward. When the vertical piece 52c abuts on the locking piece 51b, the range of movement of the bracket 52 in the direction away from the small door 110 is restricted.

The countersunk screw 53 is inserted through a through hole 55 provided in the end plate 121 and the bracket 51, and is further screwed into a nut 56 fixed to the vertical piece 52 c through the vertical piece 52 c of the bracket 52. The head of the countersunk screw 53 is engaged with the through hole 55 so as to be rotatable and non-insertable.
The countersunk screw 53 passes through a spring 57 that urges the brackets 51 and 52 in a direction away from each other in the width direction of the large door 120. By the urging force of the spring 57, the head of the flat head screw 53 is pressed against the end plate 121 of the large door 120, and the bracket 51 is moved to the end plate 121.
Further, the bracket 52 is pressed in a direction away from the end plate 121.

The bracket 52 has a horizontal piece 52d bent from the lower end of the vertical piece 52c in a direction approaching the end plate 121. The horizontal piece 52d is mounted on the top plate of the frame 31 of the slider 30. It is located as follows.
Further, a locking piece 52e is bent downward at the tip of the horizontal piece 52d.
It can be locked at the tip of.

The thus configured initial position adjusting means 5
