Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a sliding door that is reciprocally movable between a closed position in which a door contact surface provided on a peripheral edge of a doorway is closed to close the doorway and an open position in which the doorway is opened. Regarding sliding door unit.

[0002]

2. Description of the Related Art When a room or a building such as a house is used as a place for playing musical instruments or a place for singing at karaoke, etc., in order to prevent noise from coming to other rooms or other buildings, Soundproof walls were used for the walls that make up the rooms and buildings to prevent sound from leaking outside.

Further, at the entrance and exit of the room or building, it is necessary to provide packing around the door or around the door so that the door and door are in close contact with each other in order to prevent sound from leaking. However, the door originally needs a dead space for opening and closing, which is extremely low in space efficiency. This is a big problem, especially in areas with poor housing conditions.

[0004]

Sliding doors are known as those that do not produce unnecessary space for opening and closing. Since this sliding door is moved parallel to the doorway and the wall, there is no dead space just for moving like a door, and space efficiency is high.

However, when the sliding door is used as a soundproof sliding door, the following problems occur. That is,
There is no component that moves toward the door in the movement of the sliding door,
I can't apply the force that makes it stick to the door. Therefore, even if the sliding door is slightly warped, a gap is formed between the sliding door and the door, which causes a problem in adhesion. Normally, the door is formed to be long in the vertical direction, and the adhesion between the sliding door and the doorway, especially in the vertical direction, becomes a problem.

The above-mentioned problems are the same not only when the sliding door is used for soundproofing, but also when it is used for airtightness and heat insulation. In order to solve the above-mentioned problems, the present invention provides a sliding door unit that can surely bring a sliding door and a doorway into close contact with each other, achieve high soundproofing, airtightness, or heat insulation, and has high space efficiency.

[0007]

In the sliding door unit of the present invention, the door contact surface on the open position side of the vertical door contact surfaces is directed toward the open position, and the sliding door unit It is equipped with a protruding abutting part that is attached in the vertical direction and sticks to the vertical door contact surface on the open position side when it projects toward the door and is in the closed position. With a parallel shape, it will reciprocate while the front and back surfaces are inclined at 0.5 ° to 4 ° with respect to the flow line of the sliding door .
And the lateral door contact surface of the doorway is also inclined at an angle parallel to the front and back surfaces of the sliding door ,
Of the front and back surfaces, the side contacting the lateral door contact surface of the doorway
The directional contact surface is the same as the sliding door approaches the closed position.
When approaching the lateral door contact surface, the sliding door reaches the closed position.
It is characterized in that it comes into contact with the lateral door contact surface at a short time .

First, according to the present invention, since the projecting abutment portion as described above is provided, when the door is closed by the sliding door, the projecting abutment portion of the sliding door is opened even though it is a sliding door. Position side door Open from the position that is spaced from the contact surface
It moves toward the contact surface and contacts the door contact surface in the open position. For this reason, the operation force for closing the sliding door also acts as a force in the direction of bringing the protruding contact portion of the sliding door into contact with the door contact surface on the open position side on the doorway side. It can be brought into close contact with the contact surface.

Further, in the conventional sliding door, when warpage occurs,
Usually, first, the center between the upper and lower sides of the sliding door is separated from the doorway, or conversely, the upper and lower sides are separated from the doorway and the adhesion is deteriorated. Since the sliding door unit of the present invention is provided with a protruding contact portion that is attached to the sliding door in the longitudinal direction of the sliding door and protrudes toward the doorway side, the protruding contact portion is a reinforcing rib that prevents the sliding door from warping. And it is difficult to warp especially in the vertical direction. Therefore, the adhesion between the doorway and the sliding door due to the warp is less likely to be destroyed.

Further, since the projecting abutment portion abuts against the door contact surface on the open position side which is directed in the open position direction and closely adheres to the door contact surface, even if the slide door is warped in the vertical direction, the main body of the slide door is in contact. Direction perpendicular to the projecting contact part that only bends along the projecting direction so that it is bent, and affects the adhesion between the projecting contact part and the door contact surface on the open position side. Almost no warp occurs in the protruding contact portion.

Therefore, even if the sliding door is warped,
Only the contact position between the protruding contact portion and the door contact surface on the open position side is displaced, and the contact property between the sliding door and the doorway is maintained. Further, in the present invention, the sliding door has a shape in which the front and back surfaces are parallel,
The front and back surfaces are inclined at 0.5 ° to 4 ° with respect to the flow line of the sliding door
It is installed so as to reciprocate in the same state, and the lateral door contact surface of the doorway is also inclined at an angle parallel to the front and back surfaces of the sliding door. Abut on the contact surface
The lateral abutment surface that moves sideways as the sliding door approaches the closed position.
Direction where the sliding door approaches the door contact surface and reaches the closed position
Is configured to abut the lateral door contact surface. This
With such a structure , when the sliding door is brought closer to the door in an attempt to close it, the lateral contact surface of the sliding door is slightly separated from the lateral door contact surface of the door, and the sliding door is moved to the closed position. As it approaches, it approaches the door contact surface in the lateral direction diagonally and adheres. On the contrary, when the sliding door is opened, the lateral contact surface of the sliding door moves obliquely away from the state of being in close contact with the lateral door contact surface. Therefore, when opening and closing, there is no movement of moving the slide door right next to it, and when the slide door is moving, the slide door is slightly separated from the door, and it can be opened and closed smoothly without requiring a large force. You can Furthermore, the lateral contact surface is set against the flow line of the sliding door.
As the sliding door moves when it is tightened, a component that moves toward the door is generated as a whole, so that even when the lateral contact surface contacts the lateral door contact surface, It is possible to apply a force to bring the door into close contact with the door, so that the sliding door and the door can be brought into close contact with each other more reliably, and high soundproofness, airtightness, or heat insulation can be achieved. by the way,
In the present invention, it is provided on one of the open position side door contact surface or the protruding contact portion, and when the sliding door is in the closed position, the other of the open position side door contact surface or the protruding contact portion. It may be equipped with a magnetic packing that magnetically sticks to
The adhesion between the sliding door and the doorway is improved.

The magnetic packing is inserted into and supported by, for example, a groove formed in the door contact surface on the open position side.
In this case, the magnetic sticking packing protrudes from the inside of the groove by being screwed into the groove from the back of the vertical member (the vertical 12, 62 in the embodiment described later) forming the door contact surface on the open position side. An adjusting screw for adjusting the amount may be provided.

Further, in order to reduce the influence of the warp of the sliding door, the door contact surface on the closed position side is directed toward the open position, and the front end surface on the closed position side of the sliding door is in the closed position. Alternatively, it may be configured to be in close contact with the door contact surface on the closed position side. That is, the other vertical (upward and downward) door contact surface is also directed toward the open position, and the sliding door has its front end surface close to the closed position close to the door contact surface.
For example, even if the sliding door is warped in the up-down direction, only the distortion from the sliding door body to the closed position side tip surface is bent in the direction along the closed position side tip surface. The warp in the direction orthogonal to the closed position side front end surface that affects the adhesion between the surface and the closed position side door contact surface hardly occurs on the front end surface.

Therefore, even if the sliding door is warped,
Only the close contact position between the front end surface on the closed position side and the door contact surface on the closed position side is displaced, and the close contact between the sliding door and the door is maintained. In this case, it is provided on one of the closed position side door contact surface or the closed position side tip surface, and when the sliding door is in the closed position, it is magnetically attached to the other of the closed position side door contact surface or the closed position side tip surface. A packing may be provided to further improve the adhesion between the sliding door and the doorway.

The magnetic packing is inserted into and supported by, for example, a groove provided in the door contact surface on the closed position side.
In this case, the magnetic sticking packing protrudes from the inside of the groove by being screwed into the groove from the back of the vertical member (vertical frames 8 and 60 in the embodiments described later) forming the closed position side door contact surface. An adjusting screw for adjusting the amount may be provided.

The protruding contact portion may be formed by attaching an angle member bent in a substantially L-shaped cross section to the surface of the sliding door on the doorway side. The angle member having a substantially L-shaped cross section reinforces the sliding door, more strongly prevents warping, and maintains close contact with the door. Further, the protruding contact portion may be formed by attaching a plate-shaped member so as to project toward the door opening side on a side surface on the rear end side of the sliding door when the sliding door moves in the closing position direction. .
Even in the case of this plate-shaped member, the sliding door is reinforced to prevent warpage,
It has the effect of maintaining close contact with the doorway.

The flow line of the sliding door may be linear,
In this case, since the guide of the sliding door may be linear, the manufacturing cost is low .

[0018]

In the present invention, as described above, the lateral contact surface of the sliding door is 0.5 ° with respect to the flow line of the sliding door .
While tilted to 4 °, this slope, more preferably, may is 1 ° to 2 °. Then, at both ends of the lateral contact surface of the sliding door , 7 mm to 60 in the direction perpendicular to the flow line.
mm, more preferably raw difference in position of 7mm~25mm
It is good to be close. With such an inclination, the space efficiency is almost the same as a normal sliding door.

[0020]

As described above, the front and back surfaces of the sliding door are the flow lines of the sliding door.
To install the sliding door to be inclined relative to the sliding door has one is by rail guide if the configuration is a reciprocable between a closed position and an open position, the sliding door relative to the rail It is good if the mounting positions in the thickness direction of the sliding door are different on the left and right.

Further, in the case of the structure in which the left and right sides of the sliding door are respectively guided by the two rails that are displaced in parallel, since the positions of the two rails are displaced ,
Even if you do not change the mounting position in the thickness direction of the sliding door on the left and right,
Install the sliding door so that the front and back surfaces of the sliding door are inclined with respect to the flow line of the sliding door.
Can be placed . In addition, each sliding door unit described above,
If the purpose is soundproofing, the soundproofing function can be more sufficiently fulfilled.

On the lower surface side of the upper frame 4, the door stop lateral member 14
As shown in FIG. 5, a suspension rail 18 is fitted and screwed into the groove 4a provided on the inner side of the room. A groove 24 is provided on the upper surface side of the lower frame 6 and on the indoor side of the door support lateral member 16.
Are formed. A substantially U-shaped floor rail 25 is fitted in the groove 24 and is fixed with screws.

Further, grooves 14b, 16 are formed on the side surfaces 14a, 16a on the indoor side (sliding door 28 side) of the door member lateral members 14, 16.
b, the position of the sliding door 28 in the state where the sliding door 28 completely opens the doorway E in the surface of the upright 12 (this position is hereinafter referred to as an “open position”. The position of the sliding door 28 in the closed state is referred to as a "closed position".)
The surface 12a facing the side is provided with the groove 12b, and the surface facing the open position side of the vertical frame 8; in the case of the first embodiment, the surface on which the door slide 30 is formed, A groove 8b is provided on the bottom surface 30a of the door opening 30.

These grooves 14b, 16b, 12b, 8b
Are continuous, and the magnetic packing 32 is inserted and attached over the entire circumference. These grooves 14b, 16
side surfaces 14a, 1 to which b, 12b, 8b are attached
6a, the surface 12a and the bottom surface 30a function as a door contact surface (hereinafter, the side surfaces 14a and 16a, the surface 12a and the bottom surface 30a are collectively referred to as the door contact surfaces 14a, 16a and 12).
a, 30a. ). As shown in FIG. 6, the groove 33 connecting the horizontal grooves 14b and 16b to the vertical grooves 12b and 8b may be a magnetic packing 32, but a sound absorbing material such as foam or a sound insulating material such as soft rubber may be used. You may arrange a material.

The grooves 14b, 16b, 12b and 8b do not have to be continuous. For example, the groove 14b and the groove 12b,
The groove 33 corresponding to a total of four places of the connecting portion with 8b and the connecting portion with the groove 16b and the grooves 12b and 8b does not have to exist, and a sound absorbing material such as foam or a soft material is simply provided at a position corresponding to the groove 33. A sound insulating material such as rubber may be arranged.

The Toto lateral members 14, 16 are formed so that the width gradually becomes wider from the mullion 12 toward the vertical frame 8, which
The side surfaces 14a and 16a of the respective sides are with respect to the flow line M of the sliding door 28.
Tilted by 0.5 ° to 4 °.

Suspending wheels 40 and 41 are attached near the left and right ends of the upper end surface 28a of the sliding door 28, respectively. As shown in FIG. 5, the suspension wheels 40 and 41 are arranged in the suspension rail 18, and the rotary shaft 4 is inserted through the split groove 18 a of the suspension rail 18.
It is attached to the sliding door 28 rotatably at 0a. Since the suspension vehicles 40 and 41 each have two pairs of wheels,
It is possible to move smoothly inside the suspension rail 18.
As a result, the upper portion of the sliding door 28 is guided by the inner surface of the suspension rail 18 during movement.

Guide shafts 42 and 43 are provided near the left and right ends of the lower end surface 28b of the sliding door 28, and are inserted into the floor rail 25. By this,
The lower part of the sliding door 28 is guided by the floor rail 25 during movement. Therefore, by the guide by the suspension rail 18 and the floor rail 25, the flow line of the sliding door 28 becomes as shown by the one-dot chain line in FIG.

The suspension wheels 40 and 41 and the guide shaft 4
2 and 43 are different in the attachment positions in the thickness direction of the sliding door 28 on the left and right sides of the sliding door 28. When the sliding door 28 is closed, the suspension wheel 40 and the guide shaft 42 are attached unevenly on the outdoor side (door side E side) at the door end side DH that is the leading end in the moving direction when closing the sliding door 28. On the side DT, the suspension vehicle 41 and the guide shaft 43
Are unevenly distributed on the indoor side (on the side opposite to the doorway E).

[0033] Therefore, the thickness is constant sliding door 28, the contact surface 28c which is a surface of the outdoor side, it a state of being inclined 0.5 ° to 4 ° relative to the flow line M of the sliding door 28 Is installed . <br/> The inclination of the contact surface 28c of the sliding door 28 depends on the side surfaces 14a and 16a of the above-described door stop lateral members 14 and 16 and the sliding door 2.
The inclination is such that the contact surface 28c of No. 8 becomes parallel .

An angle member 46 having a substantially L-shaped cross section is provided on the contact surface 28c of the sliding door 28 adjacent to the end surface 28d of the sliding door 28 on the rear side DT (open position side), on one side 46a side thereof. It is fixed to the contact surface 28c of the sliding door 28. The other piece 46b of the angle member 46 (hereinafter referred to as "protruding contact portion") is projected from the contact surface 28c to the doorway E side, that is, the outdoor side. Of the surfaces of the protruding contact portion 46b, the surface adjacent to the contact surface 28c serves as the protruding contact surface 46c, and when the sliding door 28 is moved to the closed position, the one surface 12a of the upright 12 on the doorway E side. It comes into contact with the magnetic packing 32.

The sliding door 28 is provided with strip-shaped steel plates 47 on the upper and lower edge portions of the contact surface 28c and the front end surface 28e in the closing position direction. Soundproof sliding door unit 2 configured in this way
When closing the sliding door 28, the contact surface 28c of the sliding door 28 is
As described above, the sliding door 28 is inclined by 0.5 ° to 4 ° with respect to the flow line M.
Because it is kicked, if closed before, that the sliding door 28 is in the open position, as shown in broken line in FIG. 4, the door leading end side DH
Abutting surface 28c and side surfaces 14a, 16a of magnetically sealed packing 3
2 is sufficiently separated, but as shown by the solid line, when the sliding door 28 is closed, that is, in the closed position, the sliding door 2 is completely closed.
The contact surface 28c of No. 8 and the magnetic packing 32 of the side surfaces 14a and 16a are in contact with each other. That is, according to the progress closing direction of the sliding door 28 gradually abutment surface 28c of the sliding door 28 Hazuki close to the side surface 14a, 16a, abuts so as to collision to magnetically attached gasket 32. Since the strip-shaped steel plate 47 is provided at the position of the contact surface 28c that comes into contact with the magnetic packing 32, the magnetic packing 32 has the magnet 32 provided on its head.
The contact surface 28c by the magnetic force of b (shown in FIG. 7 described later).
Securely adheres to.

At the same time , for the surface 12a of the cube 12 ,
Projection of angle members 46 provided on the sliding door 28 contact surface 4
6c approaches and contacts the magnetic packing 32 so as to collide with it. Since the angle member 46 is made of steel, the cube 1
Due to the magnetic force, the magnetic packing 32 on the second surface 12a firmly adheres to the protruding contact surface 46c.

Furthermore, at the same time, with respect to the bottom surface 30a of the door Jakuri 30 of the vertical frame 8 approaches the tip end surface 28e of the sliding door 28, it abuts so as to impinge on magnetically attached gasket 32.
Since the strip-shaped steel plate 47 is provided on the tip end surface 28e of the bottom surface 30a of the door opening 30 which comes into contact with the magnetic packing 32, the magnetic sticking packing 32 is attracted by its magnetic force.
Securely adheres to.

In this way, when the sliding door 28 is closed, the contact surface 28c, the tip surface 28e and the protruding contact surface 46 are formed.
c are door contact surfaces 14a, 16a, 12a, 30
A component that moves toward a is generated, and a force for closely contacting the doorway E can be applied to the sliding door 28, so that the sliding door 28 is firmly attached.
Contact surface 28c, tip surface 28e and protruding contact surface 46c
Can be closely attached to the magnetic packing 32.

Therefore, the interior of the room can be completely sealed and sound leakage can be prevented. Of course, at the same time, high airtightness or heat insulation can be achieved. Further, when closing the sliding door 28, the sliding door 28 is the last to come into contact with the magnetic packing 32, and the sliding door 28 does not move while sliding in contact with the magnetic packing 32. The large frictional force with the magnetic packing 32 does not hinder the closing operation.
This means that even when the sliding door 28 is opened, the sliding door 28 is first detached from the magnetic packing 32, so that the sliding door 28 after that is removed.
Will not interfere with the movement of the.

Further, since the sliding door 28 itself has a slight inclination with respect to the flow line M, a large moving space is not required when the sliding door 28 is opened and closed, and the space efficiency is almost equal to that of a normal sliding door. Does not fall. In addition, since the mechanism is simple, the manufacturing cost is low.

Further, in the sliding door 28 of the first embodiment, the angle member 46 is attached in the vertical direction. In particular, the protruding contact portion 46b of the angle member 46 projects in a direction perpendicular to the plate surface of the sliding door 28. Therefore, since the protruding contact portion 46b prevents the sliding door 28 from bending in the thickness direction, the sliding door 28, which normally tends to warp in the vertical direction, does not easily warp. Therefore, the adhesion between the doorway E and the sliding door 28 is less likely to be destroyed by the warp.

Further, the protruding contact portion 46b is in contact with the surface 12a of the upright 12 facing the open position and is in close contact therewith, and the tip surface 28e of the sliding door 28 is also directed toward the open position. Since it comes into contact with the bottom surface 30a of the door opening 30 and comes into close contact therewith, even if the sliding door 28 warps in the vertical direction, the surface 12a or the bottom surface from the sliding door 28 main body to the protruding contact portion 46b or the front end surface 28e. It does not move in the direction away from 30a, but only in the direction in which it comes into contact and is disturbed.
There is no influence on the adhesiveness between 2a or the tip surface 28e and the bottom surface 30a.

Therefore, even if the sliding door 28 is warped, the close contact between the sliding door 28 and the doorway E can be maintained. In the first embodiment, as shown in FIG. 6, the door contact surface 14 is moved by the suction force of the magnetic packing 32 at the end of the closing operation.
The a, 16a, 12a, 30a and the sliding door 28 are surely brought into close contact with each other, and the contact state thereafter is maintained. For this reason, an engaging device for maintaining the closed state of the sliding door 28 is not provided, but a hook is provided on the sliding door 28 and a ring portion is provided on the vertical frame 8 so that the hook and the ring portion are engaged with each other. The sliding door 28 in the closed position may be fixed.

Further, the door contact surfaces 14a, 16a, 12a,
Attach a steel plate to the 30a instead of the magnetic packing 32,
Contact surface 28c of sliding door 28, tip surface 28e, protruding contact surface 4
A magnetic packing may be attached to 6c. In the first embodiment, in order to finely adjust the protrusion amount of the magnetic packing 32, an adjusting device as shown in FIG. 7 may be provided.

That is, the grooves 8b, 12b, 14b, 16
Instead of directly inserting the leg portion 32a of the magnetic packing 32 into the leg portion inserting groove 50 opening at the bottom surface of b, and attaching the adjustment case 52 to the leg portion 32a,
With the adjustment case 52 attached, the leg insertion groove 50
Insert inside. The adjustment case 52 is harder than the rubber magnetic packing 32 and can easily slide in the leg insertion groove 50 if a strong force is applied.

From the opposite side of the grooves 8b, 12b, 14b, 16b, a plurality of holes 54 communicating with the leg insertion grooves 50 are formed at predetermined intervals. And the bottom surface 54 of the hole 54
On the edge of the leg insertion groove 50 in a, the demon nut 56
Is screwed in and attached. This demon nut 56
An adjusting screw 58 is screwed into a screw hole 56a at the center of the. Therefore, if the head 58a of the adjusting screw 58 is rotated by the driver D, the tip 58b of the adjusting screw 58 is
Can be moved forward or backward.

If the amount of protrusion of the magnetic packing 32 is insufficient, rotate the adjusting screw 58 with the driver D and press the adjusting case 52 with the tip 58b, and the entire magnetic packing 32 will be removed. Since it moves forward, the amount of protrusion of the magnetic packing 32 can be increased. If the amount of protrusion of the magnetic packing 32 is excessive, use the screwdriver D to adjust the adjustment screw 5
If the magnetic packing 32 is pushed in from the front side after rotating 8 to retract the tip 58b, the entire magnetic packing 32 is retracted, so that the amount of protrusion of the magnetic packing 32 can be reduced.

Regarding the magnetic packing 32 inserted in the groove 8b of the vertical frame 8, the wall W obstructs after the soundproof sliding door unit 2 is installed, and the protrusion amount of the magnetic packing 32 cannot be adjusted. It can be adjusted by removing the vertical frame 8. Further, instead of directly attaching the magnetic packing 32 to the vertical frame 8, the door frame 30 and its bottom surface 30a are attached to the vertical frame 8.
If a door stop vertical member having a groove formed in it is detachably provided as a separate member, and the door stop vertical member is attached to the magnetic packing 32 as shown in FIG. 7, the door stop vertical member is removed to form a vertical frame. Even if 8 is left as it is, the amount of protrusion of the magnetic packing 32 can be easily adjusted by the driver D from the back side of the door member vertical member, and after adjustment, it may be returned to the vertical frame 8 again.

[Second Embodiment] FIG. 8 is a block diagram of a soundproof sliding door unit 5 of a second embodiment corresponding to FIG. 4 of the first embodiment.
It is a partial explanatory view of FIG. FIG. 9 is a perspective view of the sliding door 88. The vertical packing 60, the upright 62, and the magnetic packing 82 attached to the upper and lower two door stop horizontal members 78 are the same as in the first embodiment. Further, the strip-shaped steel plates 97 attached to the upper and lower edge portions of the contact surface 88c and the front end surface 88e are also present as in the first embodiment.

The basic difference from the first embodiment is as follows.
In the first embodiment, the suspension rail 18 is one,
In the second embodiment, as indicated by the alternate long and short dash line, it is divided into two suspension rails 66, 67 and arranged so as to be shifted in parallel. The suspension rail 66 arranged in the closed position has the same length as the other suspension rail 67 arranged in the open position, but is shifted to the right side in FIG. 8, that is, to the indoor side. .

The suspension rail 66 is provided with a suspension wheel 90 on the door end side DH, and the suspension rail 67 is provided with a suspension wheel 91 on the door end side DT. These suspension wheels 90 and 91 are provided on the center line of the upper end surface 88a of the sliding door 88. As for the floor rails 75 and 76 embedded in the lower frame 56,
Similarly to the suspension rails 66 and 67 indicated by the alternate long and short dash line, the suspension rails are divided into two and arranged in parallel with each other, the floor rail 75 is provided with a guide shaft 92, and the floor rail 76 is provided with a guide shaft 93. Two guide shafts 9
2 and 93 are also provided on the center line of the lower end surface 88b of the sliding door 88.

The sliding door 88 has two suspension rails 6 of the same length.
Since it extends over 6, 67 and two floor rails 75, 76 of the same length, the lateral length of the sliding door 88 is slightly longer than the distance between the vertical frame 60 and the upright 62. For this reason,
The mounting position of the angle member 96 is not near the end portion of the sliding door 88 on the rear side DT, but near the end portion, that is, slightly on the door tip side D.
It has been moved to the H position. Thus, the protruding contact portion 96b can be brought into close contact with the magnetic packing of the surface 62a of the upright 62.

In the second embodiment, the suspension rail 6 is thus constructed.
6, 67 and the floor rails 75, 76 are respectively divided into two pieces having the same length and are arranged in parallel with each other, so that the suspension vehicles 90, 91 and the guide shafts 92, 93 are arranged on the center line of the sliding door 88. Even if provided, like the first embodiment, the sliding door 88 is slightly rotated counterclockwise, that is, the sliding door 8
The contact surface 88c of 8 can be slightly moved toward the closed position. Further, since the angle member 96 is arranged in the vertical direction near the center of the sliding door 88 as compared with the first embodiment, it is easier to prevent the entire sliding door 88 from warping. Therefore, the same effect as that of the first embodiment can be achieved.

Further, it is the same as in the first embodiment that the protrusion amount of the magnetic packing can be adjusted.
The suspension wheels 90, 91 and the guide shafts 92, 93 do not need to be provided on the center line of the sliding door 88.
8c can be moved slightly toward the closed position.

[Third Embodiment] The difference of the third embodiment from the first embodiment is that, as shown in FIG.
The point is that a door neck 140 is formed in place of the hanging vehicle, and a door wheel 142 is attached in place of the guide shaft.

Correspondingly, the Kamoi cap 146 is attached to the groove 144a of the upper frame 144 instead of the suspension rail, and the V rail 150 is attached to the groove 148a of the lower frame 148 instead of the floor rail. . The other structure is basically the same as that of the first embodiment.

With this configuration, it is not necessary to use an expensive suspension vehicle, and an inexpensive door roller 142 is sufficient. Therefore, the manufacturing cost can be reduced. In addition, the door 140 is the sliding door 13
8 is formed as a ridge over the entire length of the upper end surface 138a. Therefore, even if a problem occurs in the adhesion due to the magnetic packing 152 in the upper part of the sliding door 138, the sound does not leak to the outside unless the sound is bent between the door 140 and the Kamoi cap 146. Since the sound is greatly attenuated by this bending, the soundproof effect can be maintained. Further, even if there is no problem in the adhesiveness due to the magnetic packing 152, the soundproofing effect can be further enhanced.

Further, when the sliding door 138 is in the closed position, the reaction force from the magnetic packing 152 toward the indoor side acts on the sliding door 138, and the side surface 140 of the door neck 140 on the indoor side.
Since "a" and the side surface 146a on the indoor side of the Kamoi cap 146 are pressure-bonded to each other, the sound is less likely to leak.

[Others] The strip-shaped steel plates 47, 97 are, for example, as shown in the sectional view of FIG.
Although it is attached to the sliding doors 28, 88, 138 by a, the surface of the strip-shaped steel plates 47, 97 is provided with a lubricating layer 47b of Teflon, ultra-high-molecular polyethylene, polyacetal, polypropylene, acrylic, nylon, etc., which has little friction and is durable. Is also good. In this way, in particular, by covering the surfaces of the strip-shaped steel plates 47, 97, it is possible to prevent the magnetic packing from being damaged or worn at the corners or surfaces of the strip-shaped steel plates 47, 97. Further, especially when opening the sliding doors 28, 88, 138, a relatively large force may be required at first due to the magnetic force, but since the frictional force is small, it is relatively small even at the beginning of the opening operation. The sliding doors 28, 88, 138 can be moved smoothly.
