  On the other hand, the elastic deformable body 26 is an elongated body in the left-right direction formed of a rubber elastic material, and is elastically deformed by being positioned above the narrow neck portion 26a via the narrow neck portion 26a cut out in the indoor and outdoor directions. The support head 26b is formed with difficulty, and the first and second sealing portions 26c and 26d are located below the narrow neck portion 26a and are easily elastically deformed. The elastic deformable body 26 has the support head portion 26b held by the holding piece portion 25b by fitting the pair of holding piece portions 25b formed on the support body 25 into the narrow neck portion 26a. It is set so as to be supported in a state where the retaining is made. The elastic deformable body 26 is incorporated into the support 25 by placing the support head 26b of the elastic deformable body 26 above the holding piece 25b at either the left or right end of the support 25, and the narrow neck 26a. The holding unit 25b is fitted in and is slid toward the other side in the left-right direction. In this assembled state, the sealing unit 24 is provided below the support 25 with the first and second sealing portions 26c and 26d. Is set so as to be elastically deformable.

In the present embodiment, the first and second sealing portions 26c and 26d of the elastic deformable body 26 branch out indoors and outdoors with a predetermined gap immediately below the narrow neck portion 26a. The first and second sealing portions 26c and 26d are formed so as to be laminated indoors and outdoors, and the upper ends of the first and second sealing portions 26c and 26d are in an integrated state. The lower end portion (the end portion on the floor surface side) is branched so that each can be elastically deformed individually. Furthermore, as shown in FIG. 12, in the natural state, the first sealing portion 26c is shorter in the vertical direction (opening / closing direction) than the second sealing portion 26d, and the amount of elastic deformation of the first sealing portion 26c is the second. Although set to be smaller than the elastic deformation amount of the sealing portion 26d, the first and second sealing portions 26c and 26d are biased toward the indoor side rather than the indoor side surface 26f of the sealing body 26. Is doing . Incidentally, the vertical length of the second sealing portion 26d is the length obtained by subtracting the first sealing portion 26c from the second sealing portion 26d, that is, the length extending downward from the first sealing portion 26c. Is set to a length that can absorb variations in the levelness of the floor surface, and is set to be approximately 20 mm in the present embodiment.
Furthermore, the left and right end portions of the second sealing portion 26d are notched, and the first sealing portion 26c is formed to be longer than the length in the left-right direction of the second sealing portion 26d. Thereby, when the lowermost panel body PD provided with the sealing unit 24 is incorporated in the guide rail G, as shown in FIG. 6, the first sealing portion 26c located on the indoor side has the guide pieces 5b, 6b. The second sealing portion 26d located on the outdoor side is not inserted into the vertical and horizontal rail portions 5 and 6 but is inserted into the long vertical and horizontal rail portions 5 and 6. Is configured to have a length located in the opening.
In addition, when the first and second sealing portions 26c and 26d are elastically deformed, the lower end edge portion of the first sealing portion 26c comes into contact with the intermediate portion in the vertical direction (opening and closing direction) of the second sealing portion 26d. The first and second sealing portions 26c and 26d are both configured to be offset toward the indoor side and to be inclined with respect to the panel surface.

In this, the closing operation of the door body 1 is stopped in a state where the first sealing portion 26c having a short length in the vertical direction is in contact with the floor surface and slightly deformed, and in this state, the fully closed posture is obtained. Is set to Thereby, in the process of closing the door body 1, as shown in FIG. 13, the second sealing portion 26d having a long vertical length comes into contact with the floor surface in advance, and from this state, the door body 1 When further closing operation is performed, the lower end edge portion of the first sealing portion 26c located indoors relative to the inner surface 26f of the upper end chamber of the sealing body comes into contact with the intermediate portion in the vertical direction of the second sealing portion 26d from above. While the second sealing portion 26d is greatly elastically deformed indoors in the state , the first sealing portion 26c is in contact with the floor surface and slightly deformed. In this state, the closing operation of the door body 1 is stopped. Thus, the door body 1 is set to be in a fully closed posture.
In the fully closed posture of the door body 1, as shown in FIG. 14, the first and second sealing portions 26 c and 26 d are both elastically deformed so as to fall into the indoor side, and the first and second sealing portions There is no gap formed between the stop portions 26c and 26d, and the lower end edge of the first sealing portion 26c is in contact with the second sealing portion 26d and stacked from above. It is set so as to be elastically deformed in the state, whereby the first sealing portion 26c functions to further press and reinforce the sealing state by the second sealing portion 26d with respect to the floor surface. The stopper is configured to be further improved.

Further, in this case, the first sealing portion 26c is set to be shorter than the second sealing portion 26d, and the deformation amount is set to be smaller than that of the second sealing portion 26d. The first sealing portion 26c that is inserted into the guide rail G (horizontal and vertical rail portions 5 and 6) to seal is reduced in deformation amount in the guide rail G and is elastically deformed by the guide rail G. It is set so as not to be disturbed. Thus, a gap is not formed in the vicinity of the guide rail G, and it is set so that reliable sealing can be performed.
On the other hand, the second sealing portion 26d having a length in the vertical direction longer than that of the first sealing portion 26c is sealed with the floor surface even if the floor surface is inferior in horizontal level due to large elastic deformation. In addition, since it is not inserted into the guide rail G, damage due to the guide rail G can be avoided. As a result, large elastic deformation based on contact with the floor surface can be ensured. In addition, it is possible to reliably perform sealing with the guide rail G, and to prevent problems such as light leakage and rainwater intrusion when the door body 1 is fully closed.
Incidentally, in the present embodiment, the guide groove depth of the R-shaped rail portion 7 is formed to be vertical and shallower than the guide groove depth of the horizontal rail portions 5 and 6, and the elastic deformation body 26 is formed on the R-shaped rail portion 7. It is not inserted. Therefore, in the present embodiment, the R-shaped rail portion 7 is configured so as not to have a problem that the elastic deformation body 26 is worn.

  The elastic deformation body 26 is inserted into and supported by the support 25 so as to be slidable in the left-right direction. In this case, there is no special provision for restricting the movement of the elastic deformation body 26 in the left-right direction. However, in the present embodiment, a pair of suspension body mounting brackets 18 are provided at both left and right ends of the support body 25. It is fixed. The side surface shape of the suspension body mounting bracket 18 and the side surface shape of the support body 25 are formed in substantially the same shape, and are the lower part of the narrow neck portion 26a of the elastic deformable body 26. The lower piece 18j in the lower half of the inner side in the left-right direction of the suspension body mounting bracket 18 is set adjacent to the connecting portion 26e to which the stop portions 26c and 26d are integrally connected. The elastically deformable body 26 is set so as to be subjected to left-right movement restrictions by the suspension body mounting bracket 18.

  In the present embodiment configured as described, the door body 1 opens and closes the opening by receiving movement guidance by the guide rails G provided on both sides of the opening as the opening and closing machine 9 is driven forward and backward. And in this thing, although the sealing unit 24 is provided in the lower end part of the lowest end panel body PD, as for the elastic deformation body 26 which comprises this sealing unit 24, right and left both ends are the guide rail G (vertical, horizontal rail). A first sealing portion 26c that is inserted into the portions 5 and 6) and has a short vertical direction (opening / closing direction), and a second sealing portion 26d that is not inserted into the guide rail G and has a long vertical length. And a second sealing portion 26d that comes into contact with the floor surface and elastically deforms prior to the first sealing portion 26c when the door body 1 is closed. As a result, even if the elastic deformation of the first sealing portion 26c that is inserted into the guide rail G and closes the gap between the guide rail G and the second sealing portion 26d is greatly elastically deformed, Since the floor surface can be reliably sealed in the opening, an overhead door with improved sealing of the opening can be provided.

  Moreover, in the case where the present invention is implemented, the first and second sealing portions 26c and 26d are formed in an indoor / outdoor laminated shape, and the first and second sealing portions 26c and 26d. Since the lower end portion (the end portion on the floor surface side) is branched and is in a free state, the first and second sealing portions 26c and 26d are individually elastically deformed along the floor surface. Thus, the sealing performance at the opening (the sealing performance at the guide rail and the floor surface) can be further enhanced.

  Moreover, in this case, the first and second sealing portions 26c and 26d are formed in a state of branching below the narrow neck portion 26a, and the upper portion is integrated, so that the support head portion 26b is supported by the support body 26b. 25, the sealing unit 24 can be easily configured, and the elastic deformation body 26 can be easily assembled.

  Furthermore, in this, both the first and second sealing portions 26c and 26d are formed to be offset toward the indoor side, so that they are easily elastically deformed by contact with the floor surface, and are based on the elastic deformation. Since the lower end edge of the first sealing portion 26d comes into contact with the second sealing portion 26c, the lower end portions of the first and second sealing portions 26c and 26d are branched and individual elastic deformation is allowed. The first sealing portion 26d is elastically deformed by the elastic deformation of the second sealing portion 26d, and the first sealing portion 26d is deformed so as to press the second sealing portion 26c. Sealability can be further improved.

  Further, in this structure, the sealing unit 24 is provided between the suspension body mounting brackets 18 arranged at the left and right ends of the lower end portion of the lowermost panel body PD, and the suspension body mounting bracket 18 is supported by Since the elastic deformation body 26 arranged so as to be movable in the left-right direction with respect to the body 25 (sealing unit 24) is configured to be restricted, the configuration can be simplified and the member can be shared. it can.

Needless to say, the present invention is not limited to the above-described embodiment, and as the sealing body, first and second sealing members such as the elastic deformation body (sealing body) of the first embodiment are used. In addition to the structure in which the upper end portion of the sealing portion is integrated and laminated in the indoor / outdoor direction, the first and second sealing portions are separately formed, and these pair of sealing portions are the bottom end panel body. It is also possible to employ a configuration incorporated in the second and third embodiments shown in FIG.
The elastic deformable body 27 of the second embodiment shown in FIG. 15 (A) is similar to the first embodiment in that the support head 27b is formed above the narrow neck 27a. The first and second sealing portions 27c and 27d are integrally formed below 27a. These first and second sealing portions 27c, 27d are formed in a solid shape with no gap between the facing indoor and outdoor directions, and are cut out along the portions indicated by phantom lines at the left and right end portions, The first sealing portion 27c is located on the indoor side and is fitted into the guide rail, and the second sealing portion 27d is located on the outdoor side and is not fitted into the guide rail. In this case, the second sealing portion 27d that deforms in contact with the floor surface in the course of the closing operation of the opening / closing body is not inserted into the guide rail and is greatly elastic along the floor surface. While being deformable, the first sealing portion 27c is fitted into the guide rail, so that a gap between the guide rail and the guide rail is closed, and an overhead door with good sealing performance can be obtained. .

  Further, the elastic deformable body 28 of the third embodiment shown in FIG. 15B is the same as the first embodiment in that the support head 28b is formed above the narrow neck portion 28a. Below the narrow neck portion 28a, the first and second sealing portions 28c, 28d are integrally formed. The first and second sealing portions 28c and 28d are formed with a gap (hollow shape) between the opposing indoor and outdoor directions, but the lower end portion of the first sealing portion 28c becomes the second sealing portion 28d. In the integrated state, the first sealing portion 28c is located on the indoor side by being cut out along the portion indicated by the imaginary line at the left and right ends, and is inserted into the guide rail, The sealing portion 28d is located on the outdoor side and is configured not to be inserted into the guide rail. Even in this case, the second sealing portion 28d that contacts and deforms the floor surface in the course of the closing operation of the opening / closing body does not fit into the guide rail, and is greatly elastic along the floor surface. While being deformable, the first sealing portion 28c is fitted into the guide rail so that the gap between the guide rail and the guide rail is closed, and an overhead door with good sealing performance can be obtained. .
