Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a soundproof door device, and more specifically, to shield noise from indoor or outdoor of a building, particularly, a single door and a wall opening. The present invention relates to a soundproof door device in which a sound insulating structure is incorporated in a mounting portion.

(Prior art and its problems) Conventionally, in a building, a door mounting device requiring soundproofing has been devised to minimize a gap between an opening and a door via a pivot hinge or the like, or to provide a door. Improving the sound insulation effect by using mohair (flocked) packing or the like at the contact portion is performed.

However, in the former, if there is a slight mounting error in the installation of the door, not only does a door stop generate a gap and the sound insulation is reduced, but the door cannot be locked,
There is a problem that only the door protrudes forward from the partition or wall surface, and it is difficult to obtain a flat surface. In the latter case, repeated opening and closing of the door causes deterioration of the packing over time, or loss of the packing due to loss of sound insulation. There was a problem. In addition,
As described in No. 86829, it is known that sound insulation is interposed between the hinge and the vertical frame of the door by interposing sound insulation packing, but the appearance of the hinge is poor because the hinge appears outside. was there.

(Means for Solving the Problems) The present invention solves the above problems, and the gist of the present invention is to provide a soundproof door device in which a one-sided door is provided at an opening of a building via a mounting member of a sound insulation structure. In the above, one side of the door body having the sound insulating packing attached to the peripheral edge and the support are connected by a hinge, and a packing receiving material for covering the hinge is erected between the sound insulating packing and the hinge. The fixed piece was extended to the hinge, the fixed piece was fixed to the door body, and when the door was closed, the sound insulation packing on one side attached to the door body came into contact with the packing receiving material and was attached to the other side at the same time. A sound insulating door device wherein the sound insulating packing is in contact with a frame material edge of the upper opening.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially omitted cross-sectional view showing a main part of the present invention, and FIG.
The figure shows a partially omitted perspective view of the mounting state of the present invention.

As shown in the sectional view of FIG.
Is attached to the peripheral edge of the door body 1 and the pillar 5 is connected to one side 11 of the door body 1 by a hinge 2, and a packing receiver for covering the hinge 2 between the sound insulating packing 3 and the hinge 2 is provided. When the material 4 is erected and the door is closed, the sound insulating packing 3 on one side 11 attached to the door body 1 comes into contact with the packing receiving material 4 and at the same time, the sound insulating packing 3 attached to the other side of the door body 1. Abuts the edges of the vertical frame member 6 and the horizontal frame members 7, shown in a partially omitted perspective view in FIG. 2, to shield the opening.

The sound insulating packing 3 used in the present invention is preferably an independent foam made of soft plastic or a soft rubber elastic body.

As shown in FIG. 1, the hinge device 2 used in the present invention includes a fixed piece 21 having a flat plate shape and a fixed piece 22 having a substantially channel-shaped cross section via a rotating shaft 20. A vertical adjusting slot 25 for mounting and finely adjusting the door body 1 in the vertical direction in FIG. 2 is provided in the door 21. A door fixing piece 221 having an angled cross section is provided at the tip of the fixing piece 22.
In one of the door fixing pieces 221, a front-rear adjustment long hole 23 for mounting and finely adjusting the door body 1 in the vertical direction in FIG. In FIG. 1, a left-right adjustment slot 24 is provided for fine adjustment by attaching the main body 1 in the left-right direction.

The packing receiving material 4 used in the present invention has one end fixed to the column 5, and stands upright so that the packing receiving portion 41 is provided between one side of the door body 1 and the hinge 2. .

Then, the hinge 2 is temporarily fixed to the support 5 by passing a bolt 26 from the vertically adjusting slot 25 provided in the fixing piece 21 to the support 5, and one side of the door main body 1 and one piece of the door fixing side 221 are previously connected. A bolt 26 is temporarily fixed to the left and right adjustment slot 24 through a bolt 26, and the other piece of the door fixing piece 221 is connected to the front and rear adjustment slot 2 at one end of the fixing piece 22.
Temporarily fasten bolts 26 to 3

Thereafter, the vertical position of the door main body 1 is finely adjusted by the vertically adjusting long holes 25 temporarily fixed to the column 5, the bolts 26 are tightened to fix the hinge 2 to the column 5, and then the fixing pieces 22 of the hinge 2 are fixed. The sound insulation packing 3 attached to the peripheral edge of the door body 1 by the front and rear adjustment long holes 23 temporarily fixed at one end of the
Finely adjust the front and rear position until it abuts on 41, tighten and fix the bolt 26, and finally finely adjust the left and right position of the door main body 1 with the left and right adjustment long holes 24 temporarily fixed on one side of the door main body 1. The door body 1 is fixed to the hinge 2 by tightening the bolts 26.

As mentioned above, the one-sided door attached to the opening of the building,
With the rotation axis 20 of the hinge 2 fixed to the column 5 as a fulcrum, the door can be opened in a large arc in the direction of the arrow by 90 °. The opening can be shielded by contacting the packing receiving portion 41, the edge portions of the vertical frame member 6, and the horizontal frame members 7, 7.

(Effects of the Invention) Since the present invention has the above-described configuration, the following effects can be obtained.

That is, in the present invention, when the door is closed by a hinge that connects between the door body and the support, the sound insulating packing attached to one side of the door body is erected at the opening / closing fulcrum, and is used as a packing receiving material that covers and hides the hinge. At the same time, the sound insulation packing attached to the other side of the door body comes into contact with the opening, and it can be finely adjusted in the vertical direction between the support and the hinge. Fine adjustments can be made, so the door body can be mounted flush with the partition or wall surface, the hinges are covered and hidden by the packing receiver, and the hinges are not visible from the outside, giving a good appearance. The sound insulation is ensured by contacting the material, and there are no mounting errors or gaps between the opening and the door body, so that the sound insulation effect and the durability are improved.
