あつた。 The airtightness of the door is mainly achieved by interposing an airtight material between the door and the door stop member on the building base.
When the floor surface is laid flat to allow for the movement of beds from room to room, such as in hospitals, the above-mentioned doorstop members cannot be installed upright on the floor, and the airtightness of the door is broken. Doors used as entrances and exits of places where it is desired to keep the room strictly airtight, such as the sterile room of a hospital, naturally require a special opening/closing structure. For example, the lower part of the door is sealed by lowering the door so that it touches the floor in the closed position, and when opening the door, lift it upwards to separate it from the floor, and then move it in a predetermined direction. A structure that opens up has been proposed. However, this elevating type door has the disadvantage that the mounting structure to the door frame and the elevating and lowering operation mechanism incorporated in the door are complicated, resulting in high manufacturing costs, and the door opening/closing operation procedure is complicated.

となく扉本体５を開放できる。 The present invention has been devised in view of these points, and one embodiment of the invention will be explained below based on the drawings. In Figs. A door stop member 3 is formed on the inner circumference of the door frame 1 excluding the floor surface 2, and an airtight rubber 4 is fixed to the door stop member 3. Therefore, the door stop member does not protrude from the floor surface 2, and the floor surface 2 is flat. The door body 5 is suspended in the air with a slight gap 6 from the floor 2 and is attached to the door frame 1 by a hinge 7 so as to be able to open and close freely, and when closed, the upper edge of the door body 5 and the vertical edges on both sides The portion elastically contacts the airtight rubber 4 of the door stop member 3 and is sealed. As shown in FIG. 3, inside the lower edge member 8 of the door body 5, a rotating horizontal shaft 9 is supported over the entire width range of the door body 5 by a bearing metal fitting 24, which will be described later. A strip-like mounting piece 10 is integrally provided to protrude in the longitudinal direction, and a substantially fin-shaped movable airtight rubber 11 that is fitted and fixed to this mounting piece 10 is attached to the opening 12 of the lower edge member 8.
It protrudes to the floor surface 2 side through. Also, the door body 5
is provided with a door lock handle 13, and a rod 14 that moves up and down in conjunction with the rotational operation of the door lock handle 13 is vertically supported within the door body 5. When the door lock handle 13 is rotated in one direction to close the door body 5, the lifting rod 14 protrudes from the top and bottom of the door body 5 and enters the lock hole 15 provided in the door frame 1 and floor surface 2. This locks the door body 5 in the closed position, and when the door lock handle 13 is rotated in the opposite direction to open the door body 5, the lifting rod 14 is moved out of the lock hole 15. It is pulled out and the lock is released. The elevating rod 14 and the horizontal rotating shaft 9 are interlocked and connected via a kinetic force converting and transmitting means that converts the elevating motion of the rod 14 into a rotating motion and transmits it to the horizontal rotating shaft 9. Therefore, when the rod 14 descends, the rotating horizontal shaft 9 rotates clockwise toward the drawing, and the movable airtight rubber 11 assumes a substantially vertical position, with its lower end touching the floor surface 2 and its upper end touching the lower edge member 8.
The door body 5 and the floor surface 2 are sealed by contacting the lower end 8a of the door body 5 (FIG. 6). Conversely, when the rod 14 rises, the rotating horizontal shaft 9 rotates counterclockwise, and the movable airtight rubber 11 is lifted up from the floor surface 2 (FIG. 7). The kinetic force conversion and transmission means connecting the rod 14 and the rotating horizontal shaft 9 is as shown in FIG.
A round-headed pin protrusion 16 is provided protruding from the rod 14.
An engagement groove 17 is carved on the circumferential surface of the pin protrusion 16.
As shown in Fig. 4, a rack 18 is carved into the rod 14 side, and a pinion 19 is formed on the horizontal rotating shaft 9 to engage these elements. As shown in FIG. 5, a pin 20 is installed on the rod 14 side, a lever 21 is extended from the horizontal rotating shaft 9, and the pin 20 is fitted into the long hole 22 of the lever 21. A lever structure is considered. In the pin protrusion engagement structure shown in FIG. Therefore, there is a difference in the rod stroke amount required to rotate the horizontal rotating shaft 9 and rotate the movable airtight rubber 11 between the two positions shown in FIG. 6 and FIG. This consideration was made to absorb the difference when the stroke amount is long. 23 is the boss. Therefore, if the door locking handle 13 is operated to lock the door after closing the door body 5, the airtight rubber 4 between the door body 5 and the door stop member 3 and between the door body 5 and the floor surface 2 will be closed. The entire circumference of the door body 5 is covered with the door frame 1 by the movable airtight rubber 11.
and sealed against the floor surface 2. Moreover, when the lock is released, the airtight rubber 11 is lifted from the floor surface 2, and the door body 5 can be opened without the airtight rubber 11 slidingly contacting the floor surface 2.

て逆の動作がなされる。 Further, as shown in FIGS. 6 and 7, the present invention has a bearing hardware 24 fixed with screws 25 inside both ends of the lower edge member 8, and a fitting portion 26 opening downward is provided on the bearing hardware 24. Both ends of the rotating horizontal shaft 9, which is interlocked and connected to the rod 14, are fitted into the engaging portion 26, and one hanging wall portion 2 of the engaging portion 26 is inserted into the engaging portion 26.
7 is formed with a rack 28 in the vertical direction, and a pinion 29 is integrally formed (or integrally equipped) on the rotating horizontal shaft 9 corresponding to this rack 28, and the rack 28 and pinion 29 are fitted together. Therefore, if the rod 14 is raised from the sealing position shown in FIG. 6 and the horizontal rotating shaft 9 is rotated in the direction of the arrow a, the horizontal rotating shaft 9 will rotate and move upward due to the engagement between the rack 28 and the pinion 29. However, the movable airtight rubber 11 is rotated upward and pulled up to open the seal, and when the rod 14 is lowered from the seal opening position shown in FIG. Then the opposite operation is performed.

られる。 As described above, the present invention has a rotary horizontal shaft equipped with a movable airtight rubber hanging so that it can rotate integrally, is supported horizontally on the bottom surface of the door body so that it can move up and down a slight distance, and this rotary horizontal shaft and door handle are A rod that is being raised and lowered is interlocked and connected via a kinetic force conversion and transmission means that converts and transmits the raising and lowering movement of the rod into a rotational movement of a rotating horizontal axis, so that when the door handle is rotated, the movable airtight rubber is moved to the floor surface. The movable airtight rubber is configured to rotate freely toward and away from the floor surface, and the airtightness between the door body and the floor surface is maintained by the rotational contact of this movable airtight rubber with the floor surface. An airtight door with a simpler structure and lower cost can be obtained than the conventional structure in which the door is raised and lowered.

Resistance is kept low,
Therefore, the load acting on the door handle is reduced, and the door can be opened and closed with less force, and when the door is closed airtight, the movable airtight packing is strongly pressed against the floor surface, thereby achieving a remarkable airtight effect.
