As shown in FIG. 2, a first rubber seal 3 a is attached to the ceiling surface 1 e of the upper side 1 a of the door body 1. The first rubber seal 3a is configured such that the upper surface 3e forms a certain inclination angle with respect to the horizontal plane so that the dimension H in the thickness direction gradually decreases as the door body 1 moves forward.
In contrast, the first seal surface 2a of the fixed frame portion 2 of the door that contacts the first rubber seal 3a is also inclined at the same inclination angle as the upper surface of the first rubber seal 3a.

Further, a second rubber seal 3b is attached to the side surface 1f of the lower side 1b of the door body 1. The second rubber seal 3 b is configured such that the side surface 3 f forms a constant inclination angle with respect to the vertical surface of the door body 1 so that the dimension D in the thickness direction decreases sequentially toward the forward side of the door body 1. .
On the other hand, the second seal surface 2b of the fixed frame portion 2 of the door contacting the second rubber seal 3b is also inclined at the same inclination angle as the side surface of the second rubber seal 3b.

Next, the sealing mechanism of the front side 1c and the rear side 1d of the door body 1, which is the remaining seal portion of the door body 1, will be described.
As shown in FIG. 3, the leading side 1c is pressed against the fixed frame portion 2 by the closing operation of the door body 1, whereby the third rubber seal 3c, the third seal surface 2c, the fourth rubber seal 3d, The four seal surfaces 2d are in close contact with each other to maintain soundproofing.

  That is, the third rubber seal 3 c is in close contact with the third seal surface 2 c of the fixed frame portion 2 in the closed state of the door body 1. Further, the fourth rubber seal 3d is configured to be in close contact with the fourth seal surface 2d of the fixed frame portion 2. As the seal mechanism for these portions, the direction of the closing force of the door body 1 is the same as the direction in which the seal portions are brought into close contact with each other. Not needed.

  In the present embodiment, the fifth seal surface 2e is further provided on the leading side 1c, the fifth rubber seal 3e is provided on the fixed frame portion 2 in contact therewith, and the rear side 1d is provided. A sixth seal surface 2f is disposed on the second frame, and a sixth rubber seal 3f is disposed on the fixed frame portion 2 in contact therewith.

  As shown in FIG. 4, each of the rubber seals 3a to 3d attached to the door body 1 is divided into a corner seal 3g and a straight portion seal 3h, and the mounting groove of the rubber seal bracket 1g shown in FIG. The corner seal 3g is inserted into 1h, and the insertion portion 3i of the corner seal 3g is inserted into the insertion hole (not shown) of the straight portion seal 3h. As the rubber seal, two types of sponge rubber 3j and a magnetite 3k having a magnet on the opposite side of the seal surface are used in combination as shown in FIG.

  As the corner portion of the rubber seal, a magnet insertion portion 3i protrudes from each side of an L-shaped sponge rubber 3j as shown in FIGS. 4 to 6, or a corner sponge rubber 3j as shown in FIG. Any configuration in which the magnetite 3k is directly connected in each side direction and the magnet insertion portion 3m protrudes from the magnetite 3k may be adopted.

Next, functions of the present embodiment will be described.
In the soundproof door of this embodiment, when the door body 1 is advanced from the open state to the closed state, the first rubber seal 3a provided on the ceiling surface 1e of the upper side 1a of the door body 1 is attached to the fixed frame portion 2 of the door. The first seal surface 2a is closely attached. This is because the first rubber seal 3a and the first seal surface 2a are inclined surfaces having the same inclination, and the thickness of the first rubber seal 3a in the vertical direction is increased toward the forward side of the door body 1. Since the space between the sealing surface 2a and the ceiling surface 1e is small, when the door body 1 is moved forward and moved from the open state to the closed state, the wedge effect causes a small forward direction. This is because a large vertical pressing force is generated by the force.

  Similarly, when the door body 1 is advanced from the open state to the closed state, the second rubber seal 3b provided on the side surface 1f of the lower side 1b of the door body 1 is disposed on the fixed frame portion 2 of the door. In close contact with the sealing surface 2b. Similarly to the above, the second rubber seal 3b and the second seal surface 2b are inclined surfaces having the same inclination, and as the door main body 1 moves forward, the horizontal direction of the second rubber seal 3b increases. Since the thickness and the space between the second seal surface 2b and the side surface 1f are small, when the door body 1 is moved forward from the open state to the closed state, the effect of the wedge This is because a large horizontal pressing force is generated by a small forward force.

  In order to generate a pressing force in the vertical direction and the horizontal direction due to the effect of the wedge, although not particularly shown, the positional deviation in the vertical direction and the horizontal direction (traveling left and right direction) of the door body 1 in the opening and closing operation of the door body 1 is performed. The configuration is such that (ga) is kept within a predetermined dimension in relation to the fixed frame portion 2.

  Further, when the door body is retracted from the closed state to the open state, the first rubber seal 3a and the first seal surface 2a, and the second rubber seal 3b and the second seal surface 2b, which are in close contact with each other, It can be easily pulled apart by moving it over a short distance with a small horizontal force compared to the adhesion force. This is also due to the wedge effect.

  In the soundproof door according to this embodiment, as described above, the door body can be easily moved to the closed state only by the horizontal movement of the door body and by applying a small horizontal force to the door body. High adhesion to the frame can be obtained. Similarly, when the door main body is shifted from the closed state to the open state, the door main body can be moved to the open state only by the horizontal movement of the door main body and by applying a small horizontal force to the door main body. That is, in the present embodiment, the sealing property, that is, the soundproofing property, and the ease of operation are compatible, and these are realized by an extremely simple configuration. This is an effect that cannot be obtained with a conventional soundproof door, and is a major feature of this embodiment. Some conventional soundproof doors employ a complicated mechanism to apply a force in the direction perpendicular to the opening and closing direction of the door in order to improve the sealing performance, and are forced to perform opening and closing operations that require labor and force. There were many. In the present embodiment, the above-mentioned problems are solved by adopting a wedge mechanism, and both high soundproofing and ease of operation are realized with a simple configuration.

Next, a second embodiment will be described.
In the present embodiment, the rubber seal on the side surface of the hallway along the lower side of the door body and the sealing surface of the fixed frame portion that opposes the rubber seal are also arranged on the room side surface of the door body. (Not shown). That is, it is attached to each one of the side surfaces along the lower side of the door body, and has a wedge shape so that the thickness in the horizontal direction decreases as it approaches the head portion from the rear portion in the opening / closing direction of the door body. The two second rubber seals 3b made and the respective fixed rubber frame portions 2 of the doors facing the respective second rubber seals 3b, and as the door body 1 approaches the closed position from the open position, The abutment surface with each of the two second rubber seals 3b is inclined in the direction approaching from both sides to both side surfaces along the lower side of the door body, and the same inclination as each of the two second rubber seals 3b. And two third sealing surfaces 2b having a corner wedge shape.
Thereby, in this embodiment, the sealing performance in the lower side of the door body is further improved, and the soundproofing effect can be further enhanced.
