The height position is set and the lower end of the door 10 is attached. That is, when the door body 10 gradually moves downward while closing along the downwardly inclined guide rail 23, the projecting piece portion 71 of the first airtight material 70 comes into sliding contact with the flat surface portion 30a.
In addition, since the first airtight member 70 is fitted to the convex portion 11d11 at the lower end of the door body 10 in a state having play in the door thickness direction and the vertical direction, the first airtight material 70 is finely moved in the vertical direction and the door thickness direction, It is possible to swing the protruding piece portion 71 side in the door thickness direction.

Moreover, the 2nd airtight material 80 (refer FIG.2 and FIG.7) is provided so that it may continue in the extension direction with respect to each of the upper frame 20, the door-end side vertical frame 40, and the vertical 50. As shown in FIG.
Each second airtight member 80 includes a base 81 fixed to a stationary part (in the illustrated example, the upper frame 20, the door-end side vertical frame 40 or the vertical 50), and the base body 10 protruding from the base 81. And a projecting piece 82 that can be bent and deformed by contact with the projection, and is provided on one side or the other side in the thickness direction on the base 81 side of the projecting piece 82 and is continuous in a direction substantially perpendicular to the bending direction. A groove 82a is provided (see FIG. 6).
The material of the second hermetic material 80 is the same as that of the first hermetic material 70, and at least a portion that contacts the door body 10 is subjected to a slip process that makes the friction coefficient smaller than other portions.
Similar to the first airtight member 70, the sliding process is a coating having a friction coefficient smaller than that of other portions by, for example, silicon, fluororesin, or other synthetic resin. It is applied only to the outer surface (see FIG. 6).

The base portion 81 has a substantially rectangular tube shape having a hollow portion, and has a plurality of fitting protrusions 81a (two on each side according to an example in FIG. 6) on both side portions thereof. Each fitting protrusion 81 a is a thin protrusion protruding from the side portion of the base portion 81 toward the protruding piece portion 82, and is continuous in the longitudinal direction of the second airtight member 80.
The plurality of fitting protrusions 81a are pressed into contact with the inner surfaces of the respective recessed portions when the base 81 is fitted into the fitted recessed portions 21a, 42a, or 51a.

Further, the protruding piece portion 82 protrudes from one of the side portions of the base portion 81 and is bent and protrudes toward the door 10 that is a contact object.
If it demonstrates in detail, this protrusion piece part 82 will exhibit the cross-sectional curve shape (refer FIG. 6) which can be bent by contact with the door 10, and the one side of the thickness direction in the base part side (in the example of illustration, a bending direction side) ) Is provided with a groove 82a so as to be continuous in a direction substantially orthogonal to the bending direction.
According to the illustrated example, the concave groove 82 a is provided at the intersection of the protruding piece 82 and the outer surface of the base 81 inside the curved protruding piece 82. The concave groove 82 a is a groove having an arcuate cross section, and is continuous over substantially the entire length in the longitudinal direction of the second airtight member 80.

Note that reference numeral 83 in FIG. 6 denotes a shape holding portion that temporarily connects the base portion 81 and the tip side portion of the protruding piece portion 82 to hold the shape of the protruding piece portion 82. This shape holding part 83 is integrally formed with the base part 81 and the projecting piece part 82, and before the second airtight material 80 is used (for example, the second airtight material 80 is fitted to the recessed portions 21a, 42a or For example, immediately after being fitted in 51a, the base 81 and the protruding piece 82 are separated from each other.
The connecting portion between the shape holding portion 83 and the projecting piece portion 82 and the connecting portion between the shape holding portion 83 and the base portion 81 have a smaller cross-sectional area than other portions in order to facilitate the separation (see FIG. 6).
Further, according to the example shown in FIG. 6, the shape of the tip portion of the projecting piece portion 82 is a convex portion having a semicircular cross section. However, the shape is not limited to this, and other shapes can be used as long as the airtight performance in use is satisfied. For example, it is possible to have a rounded cross-sectional shape similar to the end of the shape holding portion 83, a sharp cross-sectional shape, or the like.
Further, since the shape holding portion 83 is integrally formed with the base portion 81 and the protruding piece portion 82 by extrusion molding or the like, the length of the shape holding portion 83 in the longitudinal direction (the direction extending to the back side (or the front side)) is long. The length is substantially the same (including the same length) as the length in the longitudinal direction of the base portion 81 and the projecting piece portion 82, but the base portion 81 and the tip end portion of the projecting piece portion 82 are temporarily connected to project. As long as the shape of the piece part 82 can be maintained, it does not need to be the same length, and can also be provided separately in the longitudinal direction.

  Moreover, the code | symbol 84 in FIG. 6 is the spacer provided as needed. A number of spacers 84 are appropriately interposed between the base 81 of the second hermetic material 80 and the bottom of the recessed portion 21a, 42a or 51a to be fitted, and the second airtight material 80 toward the door 10 side. Adjust the amount of protrusion appropriately. That is, the protrusion amount of the second airtight member 80 is adjusted by the number of the spacers 84 so as not to impair the sealing performance and to impair the operability of the door body 10.

The second airtight member 80 having the above-described configuration is formed in the fitted recess 21 a of the upper frame 20, the two fitted recesses 42 a and 42 a of the door-end side vertical frame 40, and the fitted recess 51 a of the vertical 50. , Each is fitted.
As shown in FIG. 2, the second airtight member 80 fitted to the upper frame 20 is disposed so that the protruding piece 82 is inclined downward, and the protruding end side of the door 10 is in the closing operation. Touch the surface or back.

  Further, as shown in FIG. 7, the second airtight member 80 fitted to the door end side vertical frame 40 and the second airtight member 80 fitted to the vertical 50 are arranged in the door closing direction (the left side in the figure). The projecting piece 82 is disposed so as to be inclined in the direction). According to this configuration, it is possible to reduce the frictional resistance due to the second airtight member 80 until the door 10 is closed and fully closed.

Next, the characteristic effect of the opening / closing door apparatus having the above-described configuration will be described in detail.
First, in the fully open state of the opening / closing door device, the door body 10 is located in the door pocket 60, the first airtight material 70 does not contact the lower immovable portion 30, and each second airtight material 80 is also the door body 10. Not touching.

  When the door body 10 is closed from this fully open state, the door body 10 moves obliquely downward in the closing direction along the downwardly inclined guide rail 23. In other words, the door body 10 gradually moves downward while moving in the closing direction.

During the closing operation, the second airtight member 80 in the upper frame 20 is slidably contacted with the projecting portion 82 downward (see FIG. 2) against the upper end surface of the door 10 (see FIG. 2). Increased as the door 10 moves downward. If it demonstrates in detail, the protrusion piece part 82 of the 2nd airtight material 80 in the upper frame 20 will deform | transform easily below by the ditch | groove 82a (refer FIG. 6), and the part by which the convex-curved curved surface was processed. Is brought into sliding contact with the surface of the door 10.
Therefore, the frictional resistance between the door 10 that gradually moves downward while closing along the guide rail 23 inclined in the upper frame 20 and the second airtight member 80 can be effectively reduced. .
That is, if the projecting piece portion 82 of the second airtight member 80 of the upper frame 20 is inclined upward, the door body gradually moves downward while closing along the inclined guide rail 23. The frictional resistance between the protrusion 10 and the projecting piece portion 82 inclined upward increases, and there is a risk that the smooth closing operation of the door 10 may be hindered. However, in the present embodiment, this can be prevented.

When the door 10 approaches the fully closed position by the closing operation, the projecting piece 71 of the first airtight member 70 is easily deformed by the concave groove 73 (see FIG. 3) and is a convex curved slip. The processed portion is brought into sliding contact with the flat surface portion 30a.
In this closing operation, the second airtight member 80 on the side of the vertical 50 does not contact the door 10 until just before reaching the fully closed position (see FIG. 8).

  From the above, during the closing operation of the door body 10, the frictional resistance between the door body 10 and the non-moving part is relatively small, and the closing operation of the door body 10 is performed smoothly.

And when the door body 10 is fully closed, the door body 10 door-end side fits into the fitting recess 42 of the door-end side vertical frame 40, and the surface and the back surface of the door body 10 door-end side are respectively the door tips. 7 is in sliding contact with the projecting piece 82 of the second airtight member 80 on the side vertical frame 40 side (see FIG. 7).
At this time, the second airtight member 80 on the door end side vertical frame 40 side is easily deformed by the concave groove 82 a (see FIG. 6), and the sliding portion of the convex curved surface is slidably contacted with the door body 10. Let
Further, the second airtight member 80 on the side of the vertical 50 is easily deformed by the concave groove 82a (see FIG. 6) and the sliding portion having a convex curved surface is brought into sliding contact with the door body 10 (FIG. 7). reference).
Therefore, it can prevent that the door 10 receives resistance of the protrusion piece part 82, and stops just before the door 10 side full closure.

Then, after the door body 10 is fully closed, the first airtight member 70 brings the plurality of rows of projecting piece portions 71 and 71 into contact with the flat surface portion 30 a of the lower immovable portion 30. For this reason, even if it deform | transforms so that one protrusion piece 71 may turn up by the influence of the foreign material x (refer FIG. 5) by the lower immovable site | part 30 side, an unevenness | corrugation, etc., the other protrusion piece 71 is made flat. The surface portion 30a can be contacted.
Further, at the upper end side and the left and right end sides of the door body 10, the projecting piece portions 82 of the second airtight member 80 are in contact with the surface of the door body 10.
Therefore, the airtightness between the inside and outside by the fully closed door 10 can be maintained well.

Moreover, since the 1st airtight material 70 is the structure which connected the protrusion piece parts 71 and 71 of several rows integrally by the base 72, attachment workability | operativity and attachment / detachment exchangeability are also favorable.
Further, the second hermetic member 80 has a structure in which the shape holding portion 83 is removed to be in use. For this reason, it can prevent that the protrusion piece part 82 of the 2nd airtight material 80 falls during conveyance, storage, etc. before use.

  In addition, on the door end side when fully closed, the second airtight member 80 on the upper frame 20 side and the second airtight member 80 on the door end side vertical frame 40 side may interfere with each other and overlap, or Either one or both may be cut off so as not to interfere. For example, in consideration of securing airtight performance or avoiding the door 10 from stopping immediately before being fully closed due to friction with the second airtight material 80, etc. What is necessary is just to select a structure.

  The first airtight material 70 on the lower end side of the door body 10, the second airtight material 80 on the door end side vertical frame 40 side, and the second airtight material 80 on the vertical 50 side are particularly suitable for improving airtightness. However, for example, in a situation where water flows from either one of the door thickness directions of the door body 10 in use, it is possible to expect water tightness that prevents the passage of water.

  Moreover, according to the said Example, although the 1st airtight material 70 was provided only in the lower end side of the door body 10, as another example, the 1st airtight material 70 is the upper end side of the surface or back surface of the door body 10. It is also possible to provide a structure in which the projecting piece portions 71 of the first airtight member 70 are in sliding contact with the upper frame 20.

As another example, the projecting piece 82 may be in direct contact with the surface of the door body 10.

  Moreover, according to the said Example, although the slip process of the 1st airtight material 70 and the 2nd airtight material 80 was provided only in the part to slidably contact, as another example, the said slide process is the 1st It is also possible to apply to one whole airtight material 70 or the second airtight material 80.

Moreover, according to the said Example, although the ditch | groove 73 of the 1st airtight material 70 was provided only in one side of the thickness direction of the protruding piece part 71, as another example, the said thickness direction of the protruding piece part 71 is the said. It is also possible to provide it only on the other side of one side or on both sides in the thickness direction of the projecting piece 71.
Similarly, the concave groove 82a of the second airtight member 80 is also provided only on one side in the thickness direction of the projecting piece portion 82, but as another example, it is provided only on the other side of the projecting piece portion 82 in the thickness direction. Or provided on both sides in the thickness direction of the projecting piece 71.

  According to the said Example, although the 1st airtight material 70 was made to contact the lower immovable site | part 30 in the middle of closing of the door 10, as another example, the full from the full opening of the door 10 to a full closure was carried out. It is also possible to adopt a mode in which the first hermetic material 70 is in contact with the lower immobile site 30 in the range. Also in this embodiment, the first airtight member 70 is engaged with the door body 10 in a state having play in the vertical direction and has a structure for flexibly deforming the projecting piece portion 71, so that the door body 10 is closed. An increase in frictional resistance during the process can be suppressed.
