This door apparatus D is provided in the entrance opening 1 which communicates the clinium side I and the front chamber side 0. As shown in FIG.

The entrance opening 1 has an upper border 11, a lower border 12, and vertical borders 13 and 14 installed on both sides thereof to form a substantially rectangular shape. These upper edges 11, lower edges 12, and vertical edges 13 and 14 are placed upright to form a substantially rectangular shape.

Sliding doors 2 and shutters 3 are provided between the upper border 11, the lower border 12, and both sides thereof, requiring approximately half the width of the entrance opening 1 between the longitudinal borders 13 and 14.

The sliding door 2 slides between the upper border 11 and the lower border 12 in a sliding door type.

On the other hand, the shutter 3 is provided in the longitudinal side of the Han Chinese of the access opening 1, and accommodates a sliding door in the front room side (0).

3 and 4 are enlarged cross-sectional schematic diagrams of the X and Y portions in FIG.

That is, as shown in FIG. 3, the upper frame 21 of the sliding door 2 is provided with the locking pieces 21a extending out to the clean luum side I, and the upper tenuri inside 11a. The trolley | bogie 4 which electrically drives two sets of rails 11b and 11b is provided in this.

At the lower end of the support part of this trolley | bogie 4, the hem end frame 42 is provided, and the receiving piece 43 which extended the front chamber side 0 is provided in the hem end frame 42. As shown in FIG.

The locking piece 21a is placed on the receiving piece 43.

The uneven part is provided in the contact surface of the engaging piece 21a and the receiving piece 43, and the spring v for press-contacting the engaging piece 21a is provided, and the engaging piece 21a is provided on the receiving piece 43. Make sure to fasten. In addition, guide rollers 5 and 5 are provided on the upper frame 21 and the lower frame 22 of the sliding door 2, respectively. These guide rollers 5, 5 are provided on the vertical (vertical) frame 13 or 14 side as shown in FIG.

The guide roller 5 provided in the upper frame 21 drives the inside of the upper edge 11a at the time of sliding of the sliding door 2, and the guide roller 5 provided in the lower frame 22 has the lower edge 12 The opening and closing operation of the sliding door 2 is facilitated by rolling the same in the groove 12a of ().

When the sliding door 2 is normally closed, the sliding door 2 itself is attracted, so that the gasket G1 provided in the upper border 11a abuts against the inner frame 42a of the hanging frame, so that the sliding door 2 and the upper border Confidentiality is secured between (11). In addition, as shown in FIG. 4, when installing the sliding door 2 in the entrance opening 1, the guide roller 5 installed in the lower frame 22 in the extension part (not shown) of the lower edge 12 is carried out. It is good to fit and to hang the engaging piece 21a of the upper frame 21 to the receiving piece 43 as mentioned above. In addition, the extension is closed by the cover plate, leaving the groove 12a necessary for the sliding door 2 to slide.

When the sliding door 2 is closed, the airtight device 23 installed in the lower frame 22 descends sequentially, and the gasket G2 provided at the lower end contacts the lower border upper surface 12b so that the sliding door 2 and the lower border Confidentiality between 12 is secured.

Meanwhile, as shown in FIG. 3, the shutter 3 is free to move along the center of the shutter upper frame 31 and the upper frame 11 by the top hinge TH, and the shutter lower frame 32. It is free to rotate with the lower border 12 through the approximately central floor hinge FH.

As described above, the shutter 3 has a structure in which the center hinge rotates by the top hinge TH and the floor hinge FH, but the rotation is normally prevented by a fixed lever (not shown) that moves up and down. In addition, the airtight devices 33 and 34 are respectively installed in the top frame 31 and the bottom frame 32, and the air tight devices 33 and 34 move in conjunction with the fixing lever. Therefore, when the shutter 3 is fixed, the airtight device 33 is raised, while the other airtight device 34 is lowered, so that the gaskets G3 and G4 are rims 11c and 11b, respectively. 12b).
