Description

[Detailed Description of the Invention] This invention relates to a sound insulation device between the door and the ceiling and floor in a sliding door for partitioning an assembly room, conference room, etc. as necessary.

Conventionally, as a sound insulation device for a top-hung type sliding door, a tight frame material extending the entire width of the door is supported vertically and slidably in grooves formed on the upper and lower end surfaces of the door, and the tight frame material is coated with rubber, etc. Attach the tight material and advance the above tight frame material from the upper and lower surfaces of the door using a vertical drive means to press the upper tight material to the hanging rail and the lower tight material to the floor surface, thereby insulating sound inside and outside using the door as a boundary. A type of structure is known, but with this conventional device, in order to achieve a sufficient sound insulation effect, the tight frame material must be brought into close contact with the groove wall of the door, and if it is brought into close contact, frictional resistance increases. , a large amount of force is required to raise and lower the tight frame material, so if the frictional resistance is reduced in order to raise and lower the tight frame material smoothly, sound will pass in and out through the grooves in the door that support the tight frame material, and the sound insulation effect will be improved. There was a drawback that I couldn't get enough.

The present invention provides a sound insulation device for a sliding door that can achieve a sufficient sound insulation effect and can smoothly move the sound insulation body up and down.The details of the present invention will be described below with reference to the drawings.

In Figure 1, hanging rail 1 installed on the ceiling
The pulleys 2, 2 are supported so that they can run freely, and the pulleys 2,
A sliding door 4 is connected and suspended from hanging rods 3, 3 hanging from the door 2.

The door 4 is constructed by connecting an appropriate number of horizontal bars to a frame assembled with upper and lower frame members 5 and 6 and left and right frame members 7 (the left frame member is not shown) as shown in the second and fourth figures. Decorative boards 8, 8 are stretched on both sides of the door frame, and a heat insulating material 9 such as rock wool is filled inside the door frame, and cover boards 10, 11 are installed on both the upper and lower sides with screws 12..., 1.
3..., thereby fully closing the six sides of the door, and the cover plates 10, 11 of the door thus constructed.
The surface is equipped with a sound insulating body of the proposed sound insulating device.

First, the upper sound insulation device will be explained. In FIG. 2, the sound insulation device includes a sound insulation body 14 that is vertically expandable and extends over the entire width of the door 4, and a drive means that expands and contracts the sound insulation body 14.
is the cover plate 1 with a length approximately equal to the width of the door 4.
Tight material fitting grooves 16, 16 with a substantially rectangular C-shaped cross section extending over the entire length in the longitudinal direction are provided on the upper surface of both the inner and outer sides of the holding plate 15 facing the 0, and fitting grooves 17, 17 are provided on the lower surface, respectively, and the fitting grooves 17, 17 are provided on the lower surface, respectively. groove 16,
16, elastic tight members 18, 18 each having a substantially hollow trapezoidal cross section and having a fitting base on one side are attached by fitting the bases, and fitting grooves 1 on the lower surface are respectively attached.
7 and 17, tight materials 19 and 19 with a hollow circular cross section and a large amount of expansion and contraction, each having a base for fitting into the crocodile on one side of the tight material 19, 19 having a base for fitting into the crocodile on one side thereof, are respectively attached to the sound insulating material. The base of the other side of the tight materials 19, 19 of the body 14 is attached to the cover plate 10.
The sound insulator 14 is fitted into fitting grooves 20, 20 each having a rectangular C-shaped cross section extending over the entire length in the longitudinal direction provided on the upper surface of both the inner and outer sides of the door 4, so that the entire sound insulation body 14 projects from the upper end surface of the door 4 so as to be vertically expandable and contractible. .

On the other hand, the upper end of the drive rod 21 inserted into the center of the door 4 so as to be able to rise and fall is connected to the upper frame member 5 and the cover plate 1.
The tight material 19,1 of the sound insulation body 14 passes through the
A flange 22 protrudes between the flange 9 and fixed to the protruding end.
is fixed to the sound insulation body holding plate 15 with screws 23...,
This vertical movement of the drive rod 21 causes the tight material 1 to
As shown in FIGS. 2 and 3, the cross sections 9 and 19 are elastically deformed from a circular shape to an oblong oblong shape, and extend and contract from the upper end surface of the door 4. The tight members 18 and 19 are made of an elastic material such as synthetic rubber or synthetic resin.

The drive rod 21 is connected through a guide tube 25 to a sound insulator drive device 26 consisting of a cam mechanism built into the inside of the door 4 slightly below, and is moved up and down by manual operation of the drive device from outside the door. There is.

The hanging rods 3, 3 hanging from the pulleys 2, 2 are connected to the door through holes made in the cover plate 15 between the tight members 18, 18 and 19, 19.

The lower sound insulation device is also of substantially the same construction as the upper one.

In use, a plurality of sliding doors 4 equipped with the sound insulation device of the present invention are pulled out adjacent to each other along the suspension rail 1, and the upper drive rod 21 is moved upward and the lower drive rod 21 is moved upward by operating the sound insulation drive device 26. The upper and lower sound insulators 14, 14 are moved upwardly and downwardly, and the tight members 18, 18 of the upper sound insulators are attached to the flanges 24, 24 of the suspension rail 1, and the tight members 18, 18 of the lower sound insulators are moved upwardly and downwardly. The materials 18 and 18 are brought into pressure contact with the floor surface, respectively. When the sound insulation devices of each door are similarly closed, the inside and outside of these doors 4 are sufficiently sound-insulated.

When excluding the partition by each door 4..., the upper and lower drive rods 2 can be opened by operating the drive device 26.
1 and 21, the upper sound insulating body 14 and the lower sound insulating body 14 are separated from the rail 1 and the floor surface, respectively, and the door is then pushed and moved along the hanging rail 1 to the storage position.

Another embodiment shown in FIG. 5 is an example in which the stretchable tight members 19a, 19a are formed in a dogleg shape, and the other structures are substantially the same as those in FIGS. 2 and 3.

Still another embodiment shown in FIG.
8b and 19b are made integrally, and the other structures are 2nd and 3rd.
This is an example that is substantially the same as the figure.

According to the sound insulation device for a sliding door of this invention, the upper and lower end surfaces of the door are closed, and a pair of inner and outer tight members of the sound insulation body are attached to the closed portions, so there is no groove etc. for sound to pass through as in the conventional case. It can provide sufficient sound insulation, and since the sound insulation body is attached to the top and bottom edges of the door, strong force is not required to move the sound insulation body up and down, allowing it to move up and down smoothly, and the structure is extremely simple and inexpensive. It also has the advantage of being able to be manufactured using
