Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door unit having a sliding door that can reciprocate between a closed position that closes a door and an open position that opens the door, or two sliding doors that move in a sliding state. The present invention relates to a sliding door unit having a moving path.

[0002]

2. Description of the Related Art For soundproof sliding doors, TS-25, TS-
In order to provide the soundproofing performance of 30 classes, it is particularly important to prevent sound leakage at the upper and lower ends of the sliding door. Conventionally,
To explain this problem, a special soundproof packing was used (No. 4-113689), and a sound insulation panel was attached to the surface (No. 4-87991).
Etc. are known.

[0003]

However, the former is expensive because it is a special packing, and the frictional force of the packing acts greatly when the sliding door moves, which makes it difficult to open and close the sliding door. In the latter case, sound insulation panels were conspicuous at the upper and lower ends of the sliding door, and there was a problem in appearance.

These problems are the same when the sliding door is used for the purpose of airtightness and heat insulation, as well as when it is used for the purpose of soundproofing.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a sliding door unit that has a simple structure and has sufficient soundproofing, airtightness, or heat insulation effect (hereinafter referred to as soundproofing effect), and does not cause any problem in the appearance of the sliding door.

[0005]

A sliding door unit according to the present invention is provided with an angle member which is provided with a narrow groove on the lower surface of the moving path of the sliding door along the flow line of the sliding door and is bent into a substantially L-shaped cross section. It is characterized in that one side of the angle member is closely attached to the lower end surface of the sliding door and the other side of the angle member orthogonal to the one side is inserted into the narrow groove.

The angle member is attached to the lower end surface of the sliding door on one side, and the other piece orthogonal to the one piece is inserted into the narrow groove. Therefore, the existence of the angle member is almost invisible from the appearance. Further, since the angle member is inserted into the narrow groove, which is a narrow groove, even if there is a slight gap between the other piece of the angle member and the inner surface of the narrow groove, the sound is bent so that there is no problem of sound leakage. . In fact, when the sliding door comes to the closed position, the reaction force when the doorway or the packing vertically installed in the sliding door is pressed against the sliding door, the sliding door exerts a force in the direction away from the doorway. As a result, the other piece of the angle member comes into contact with the inner surface of the narrow groove, so there is almost no gap between the other piece of the angle member and the inner surface of the narrow groove, and a sufficient soundproofing effect can be obtained. Moreover, the structure is simple and the manufacturing cost is low.

The angle member is usually made of a material such as iron which is thin but has sufficient strength. Therefore, by mounting such a material on the lower end surface of the sliding door,
The sliding door becomes more sturdy, and it is possible to prevent the sliding door from being warped in the left-right direction after manufacturing. In addition, the narrow groove is narrow enough to insert a thin and strong angle member, and is not recognized as a step when a person walks on it,
It is also extremely safe for children and the elderly. In particular, if the lower surface of the moving path of the sliding door provided with the narrow groove is formed at the same height as the floor surface, the safety is particularly enhanced for children and the elderly.

In order to move the sliding door smoothly,
For example, the door roller groove may be provided in parallel with the narrow groove, the door roller may be attached to the lower end surface of the sliding door, and the door roller may be rollably arranged in the door roller groove. Further, in order to obtain sufficient soundproofing effect at the upper end of the sliding door, for example, a kamoi groove is provided on the upper surface of the moving path of the sliding door along the flow line of the sliding door, and a nose is formed on the upper end surface of the sliding door. , The configuration may be such that this door is inserted into the Kamoi groove. If a sound absorbing material is attached to the surface of this door, it will be more effective in soundproofing.

Regarding the vertical packing, packing is provided on each of the two vertical door contact surfaces of the door contact surfaces provided around the doorway, and the open position of the sliding door is provided between these two packings. The packing that is distant from the one that is located closer to the moving path than the packing that is closer to it, and the part of the contact surface of the sliding door that corresponds to the packing that contacts the packing closer to the open position of the sliding door is far It may be configured such that it is provided so as to protrude toward the doorway side from the portion that comes into contact with the packing. According to this structure, when the sliding door moves from the open position to the closed position, when the leading end of the sliding door passes beside the packing closer to the opening position, the packing and the leading end of the sliding door are separated from each other. A large frictional force is not generated between the contact surface and the sliding door can be easily closed. Moreover, when the sliding door comes to the closed position, the contact surface of the sliding door comes to a position that matches the protruding state of the packing closer to the sliding door and the packing farther from the opening position of the sliding door. Sufficient adhesion is achieved between and.

In order to securely fix the sliding door in the closed position and further improve the soundproof effect and the like, when the sliding door moves to the closed position, it abuts on the leading end of the sliding door to prevent further movement. A movement blocking contact surface may be provided at the doorway, and one of the movement blocking contact surface or the leading end portion may be provided with a magnetic packing that is magnetically attached to the other of the movement blocking contact surface or the leading end portion.

Further, a door shackle is provided on the movement preventing contact surface in the vertical direction, and a ridge member to be inserted into the door shackle at the time of contact with the movement preventing contact surface is a leading end of the sliding door. It may be configured to be provided at the end. This is, for example, when the vertical frame that forms the door slide is a standard part, and when it is difficult to change the width of the door slide in response to changes in the sliding door position, sliding door width, etc. As for the problem that the tip of the sliding door is not inserted into the door shed, by providing a ridge member at the leading end of the sliding door and inserting the ridge member into the door shed, The gap between them is filled up for airtightness, or the sound passage is bent to improve the soundproof effect. In this case, the soundproofing effect is enhanced more particularly when the ridge member is a sound absorbing member.

The sliding door may be constructed as follows. That is, a common narrow groove is provided on the lower surface of the movement path along the flow line between two flow lines of the sliding doors that move in the pulling state, and two angle members bent in a substantially L-shaped cross section are provided respectively. One side of each angle member is closely attached to the lower end surface of the sliding door, and the other side of each angle member orthogonal to the one side is attached as a common narrow groove side, and both other sides are inserted into the common narrow groove. It is a composition.

With this structure, it is possible to use two sliding doors as a sliding door by utilizing one narrow groove. In addition, since the two angle members are narrow enough to be inserted, and are not recognized as steps when a person walks on them, it is extremely safe for the elderly.

When the angle member is attached to the lower end surface of the sliding door, a step portion is provided on the lower end surface of the sliding door, and one side of the angle member is housed and attached to the step portion. The lower end surface and the angle member are bent, and sound and the like are less likely to leak from between the lower end surface of the sliding door and the angle member, which is more effective in soundproofing.

Is arranged on the lower end surface 30b of the sliding door 30, and the mounting pieces 36a, 3
The angle member 34 is fixed to the lower end surface 30b of the sliding door 30 by screwing the screw 37 into the screw holes 36c and 36d provided in the 6b. By this, sliding door 3
Of the lower end surface 30b of 0, the second piece 38 is in a state of hanging from the contact surface 30c side.

Further, the contact surface 30c of the sliding door 30 is provided with a pressing member 40 in the vertical direction in the vicinity of the side surface 30g which becomes the rear end when the sliding door 30 is closed. As shown in FIGS. 6 and 7, the holding member 40 has a shape in which a slope 40a is formed at one corner having a rectangular cross section. This slope 40a
Is directed to the side surface 30f (corresponding to the leading end portion) that is the head when the sliding door 30 is closed.

Further, the side surface 30f is provided with a steel plate 42 at a position where it abuts against the magnetic packing 28 projecting into the door slide 8a, and when it comes into contact with the vertical frame 8 at the substantially central portion thereof, a door slide is formed. A ridge member 44 made of a synthetic resin sound absorbing member to be inserted into the hole 8a is attached.

Further, door wheels 46 are attached to the lower end surface 30b of the sliding door 30 near the side surfaces 30f and 30g, respectively. The side surfaces 30f and 30g are respectively provided with adjustment holes 46a for inserting a jig such as a driver into the door roller 46 for vertically adjusting the door roller 46.

In the sliding door 30 thus formed, as shown in FIG. 4, the door neck 32 has the kamoi groove 18 of the kamoi cap 18.
The door roller 46 is arranged in the a, and the door roller 46 is the groove 2 for the door roller of the V rail 26.
6a, and the second piece 38 of the angle member 34 is placed in the narrow groove 24 and assembled in the soundproof sliding door unit 2.

Since the sliding door 30 cannot be assembled in the soundproof sliding door unit 2 in the completely assembled state as shown in FIG. 2, the angle member 34 is provided with the second groove 38 having a narrow groove before being attached to the sliding door 30. With the angle member 34 arranged in the lower frame 6 in a state where it is inserted into the inside 24, and then the door 32 of the sliding door 30 is put in the kamoi cap 18,

The sliding door 30 can be incorporated in the soundproof sliding door unit 2 by attaching the angle member 34 already arranged in the narrow groove 24 to b. When the sliding door 30 is in the open position, the narrow groove 24 has a margin of approximately 0.5 mm to 1 mm on both sides of the second piece 38 (thickness of about 2 mm). The door 32 also has a margin of approximately 0.5 mm to 1 mm on both sides with respect to the kamoi groove 18a.

The soundproof sliding door unit 2 thus constructed
When closing the sliding door 30, the sliding door 30 is moved from the state shown in FIG. 6 to the left side of the drawing, that is, from the open position side to the closed position side. Packing 1 with a door stop 14 closely attached to the vertical frame 8
7 is provided so as to project toward the movement path side of the sliding door 30 as compared with the packing 16 of the central cuboid 12. That is, the packing 17 that is farther from the open position projects toward the movement path side of the sliding door 30 than the packing 16 that is closer.

At this time, the side surface 30f, which is the leading end of the sliding door 30, first passes in front of the packing 16 of the central cuboid 12, but since the packing 16 has a small protrusion amount, the contact surface 30c is packed. No large frictional force is generated by not contacting 16 or only slightly contacting. Therefore, the sliding door 30 smoothly passes through the inside of the packing 16 toward the vertical frame 8.

However, when the sliding door 30 comes to the closed position and the side face 30f, which is the leading end, comes into contact with the vertical frame 8, the contact face 30
Since c reaches the packing 17 having a large protrusion amount, the contact surface 30c near the leading end portion is in close contact with the packing 17. Further, the packing 16 closer to the open position is guided by the slope 40a of the pressing member 40 on the door end end side of the contact surface 30c, and further rides on the top surface 40b of the pressing member 40 to press the pressing member 40.
In close contact. That is, since the top surface 40b protruding toward the doorway E side from the contact surface 30c serves as the contact surface on the door tail side, the open position retracted from the packing 17 farther from the open position. Can be closely attached to the packing 16 closer to.

At this time, at the same time, the side surface 3 is placed inside the door shed 8a.
The ridge member 44 provided at 0f is inserted, and the steel plate 42 is magnetically attached to the magnetically attached portion 28a of the magnetically attached packing 28.
Further, the reaction force of the abutment surface 30c of the sliding door 30 and the pressing member 40 pressing the packings 16 and 17 becomes a force to push the sliding door 30 itself toward the indoor side, and as shown in FIG. The second piece 38 of the angle member 34 is pressed against the inner surface of the indoor side, and further, due to the play of the door roller 46, the second groove 38 of the angle member 34 is narrowed.
It is pressed against the inside surface of the room.

Therefore, on the left and right sides of the sliding door 30, there is no sound leakage due to the close contact of the packings 16 and 17, and the sliding door 30
At the upper part of the door, the sound passage is bent by the door 32, and the sound leakage is eliminated by the close contact between the door 32 and the kamoi cap 18. At the lower part of the sliding door 30, the sound passage is bent by the second piece 38. In addition, the second piece 38 and the narrow groove 2
No sound leakage due to close contact with 4. As a result, the entire peripheral portion of the sliding door 30 is brought into close contact, and sound leakage is prevented. Moreover, the structure is simple and the manufacturing cost is low.

The angle member 34 is attached to the lower end surface 30b of the sliding door 30 on the side of the first piece 36, the attachment pieces 36a and 36b are also attached to the side surfaces 30f and 30g, and the second piece 38 is narrow. It is inserted in the groove 24. Therefore, the existence of the angle member 34 is almost unknown from the appearance.

Further, since the angle member 34 is usually made of a material having sufficient strength such as iron, by attaching such a material to the lower end surface 30b of the sliding door 30, it serves as a reinforcing material. Further, the sliding door 30 becomes more tough, and the warp in the left-right direction after the manufacturing of the sliding door 30 can be suppressed. Further, the vertical warp of the sliding door 30 can also be suppressed by the pressing member 40 serving as a reinforcing material.

The narrow groove 24 is narrow enough to allow the angle member 34 to be inserted therein. For example, a width of about 3 to 5 mm is sufficient, and when a person walks on it, it is not recognized as a step, so that it is extremely safe for children and old people without getting caught. Especially,
If the lower surface of the moving path of the sliding door 30 in which the narrow groove 24 is provided, that is, the surface of the lower frame 6 is formed at the same height as the floor surface F, the safety is further enhanced for children and the elderly.

The lower end surface 30b of the sliding door 30 is provided with a door roller 46.
Since it is provided and is rolled in the door roller groove 26a of the V rail 26, the sliding door 30 can be smoothly moved.
Further, due to the presence of the magnetic packing 28, the sliding door 3 in the closed position is
It is possible to securely fix 0 and further improve the soundproof effect and the like.

Further, a door pickup 8a is provided in the vertical direction on the surface of the vertical frame 8 corresponding to the movement preventing contact surface, and a sound absorbing member inserted into the door pickup 8a when contacting with the vertical frame 8. Since the ridge member 44 made of is provided on the side surface 30f of the sliding door 30, in the case where the vertical frame 8 is a standard component, etc.
When it is difficult to change the width of a corresponding to a change in the position of the sliding door 30 or a change in the width of the sliding door 30, the problem that the leading end of the sliding door 30 is not inserted into the door shed 8a is described.
The ridge member 44 provided at the leading end of the
Can be solved by filling the gap between the door shed 8a and the leading end of the sliding door 30 by being inserted into.
As a result, the sound passage can be bent to improve the soundproof effect.

Cause The shield plate 251 and the narrow groove 252 and the shield plate 253 and the narrow groove 254 are
Only one of them may be provided depending on the soundproof effect.

[Fourth Embodiment] The fourth embodiment is shown in FIG.
As shown in FIG. 3, the sliding door 30 of the first embodiment is combined with a new sliding door 330 to form a sliding door soundproof sliding door unit 302.

The sliding door 330 is different from the sliding door 30 in that a rubber packing 340 is arranged at the same position instead of the pressing member 40. The other structure of the sliding door 330 is the same as that of the sliding door 30. These sliding doors 30,330
Of the lower frame 306, the doors 32 and 332 are inserted into the two kamoi grooves 318a and 318b of the kamoi cap 318 attached to the groove 304a on the lower surface of the upper frame 304, respectively.
The second pieces 3 of the angle members 34, 334 in the two narrow grooves 324.
8 and 338 are inserted, and further, door rollers 46 and 346 are inserted into the door rail grooves 328a and 329a of the V rails 328 and 329 attached to the grooves 325 and 326 provided in parallel on both sides of the narrow groove 324, respectively. There is.

When closing these sliding doors 30, 330, as shown in FIG. 14, the pressing member 40 and the packing 34 are used.
Since 0 and 0 are overlapped with each other, the packing 340 rides on the pressing member 40, and the sliding doors 30, 330 move to the packing 3
The portions of the pressing member 40 and the pressing member 40 are in close contact with each other, and their reaction forces tend to separate them from each other. Therefore, the door neck 32 comes into close contact with the inner surface 318c of the kamoi groove 318a on the indoor side, and
32 is in close contact with the inner surface 318d of the outdoor side of the Kamoi groove 318b.

The second piece 38 on one side is in close contact with the inner surface 338a on the indoor side of the narrow groove 324, and the second piece 338 on the other side is in close contact with the inner surface 338b on the outdoor side of the narrow groove 324. Therefore,
The sound passage is bent at the upper part of the sliding doors 30,330, and the sound leakage is eliminated due to the close contact between the door necks 32,332 and the kamoi cap 318, and the sound passage is bent at the lower part of the sliding doors 30,330. And the second piece 38,3
Due to the close contact between the groove 38 and the narrow groove 324, sound leakage is eliminated.
Also, in the overlapping part of the sliding doors 30 and 330, the packing 34
