To do. When the moving side airtight holding bracket is also attached to the lower end portion of the summing candy 8a of the glass shoji 2a on the outdoor side, the shape and the like of the lip portion of the moving side airtight holding bracket are the same as those of the summing heel 8a. Although the lower end portion is changed in accordance with the shape of the surface portion of the lower frame 4 that faces the lower end portion, the configuration is basically the same as the moving side airtight holding bracket 36 described above.

  Both the moving side airtight holding brackets 36 as described above are fixed in the first and second directions with respect to the moving direction of the glass shojis 2a and 2b in a state where the glass shojis 2a and 2b are moved to the closed position. It moves to a position adjacent to the side airtight holding brackets 34, 35.

A drain hole 47 (see FIG. 9) is provided in the central portion of the lower frame 4 at a portion located on the outdoor side of the labyrinth seal, and the upper surface of the lower frame 4 faces the labyrinth seal portion. The flowing rainwater is discharged below the lower frame 4.

  The sealing property of the lower side portion of the sliding door device is maintained by the structure as described above. However, in order to ensure the sealing performance of the horizontal ends of the seal lips 28, 28 of the guide members 27a, 27a and the vertical side portions constituting the structure, the rib frames 5a as described above. As shown in FIG. 20, the lower end portions of the sealing members 33a and 33b locked to the outdoor side surfaces of the locking protrusions 32a and 32b on the inner surface of 5b are discontinuous. This is because the lower corner portion of the window frame 1, that is, the continuous portion between the end of the lower frame 4 and the lower end of each of the flange frames 5a and 5b, This is because there is a structure for transferring the cover bands 25a to 25d. Therefore, in order to ensure the airtightness and watertightness of the entire sliding door device, the horizontal end portions of the seal lips 28, 28 and the lower end portions of the seal materials 33a, 33b, which are present in the lower corner portion, The structure which plugs up the discontinuous part of is needed.

  Therefore, in the case of the present embodiment, a frame lower side airtight piece 48 as shown in FIGS. 21 to 24 is provided at a continuous portion between the end of the lower frame 4 and the lower end of each of the flange frames 5a and 5b. These are fixed as shown in FIGS. Further, a heel-side airtight piece 49 as shown in FIGS. 27 to 31 is fixed to the lower end portions of the butting rods 9a and 9b as shown in FIGS. The flange side airtight piece 49 and the frame lower side airtight piece 48 prevent the horizontal ends of the seal lips 28, 28 of the guide members 27a, 27a and the lower ends of the seal members 33a, 33b. Continuous airtightness is maintained. The structure shown in FIGS. 21 to 34 shows the seal structure of the lower corner portion of the butt bar 9b and the bar frame 5b of the indoor glass shoji 2b. The sealing structure of the lower corner portion relating to the butting rod 9a of the glass shoji 2a on the outdoor side and the rod frame 5a is similarly configured except that the left and right sides are reversed. The following description will be made on the seal structure of the lower corner portion of the butting rod 9b and the rod frame 5b of the indoor glass shoji 2b.

  The frame lower side airtight piece 48 is formed with a curved guide groove 50 on the outdoor side surface thereof for guiding a portion that changes the moving direction by 90 degrees at the intermediate portion of the cover band 25c. Such a frame lower side airtight piece 48 has an upper end opening portion of the curved guide groove 50 as a lower end opening portion of a storage portion 51c, which will be described later, and a lower end (horizontal end) opening portion as an end opening of the guide groove 26a. In addition, in a state where they are continuous, they are fixed to the inside of the butted portion of the collar frame 5 a and the lower frame 4. Accordingly, the cover band 25c moves (passes) between the storage portion 51c and the guide groove 26a via the curved guide groove 50. In a state where the frame lower side airtight piece 48 is fixed to the inside of the abutting portion, the lower end surface of the sealing material 33b is in contact with or close to the upper end surface of the frame lower side airtight piece 48. The horizontal end surface of the seal lip 28 of the guide member 27a is in contact with or close to the position directly below the lower end (horizontal end) opening of the curved guide groove 50 on the inner surface of the frame lower side airtight piece 48. .

  The curved guide groove 50 guides only the indoor side edge of the cover band 25c. In general, even with this degree of guidance, it is possible to sufficiently move the storage portion 51c and the guide groove 26a. However, in order to make the movement between the storage portion 51c and the guide groove 26a smoother, the width direction central portion or the outdoor side end of the cover band 25c is formed at a portion near the lower end of the inner side surface of the collar frame 5b. It is free to fix the guide piece for guiding the edge. In addition, in order to move the cover bands 25b and 25d, each of which has one end fixed to the lower end of each summoning bowl 8a and 8b, between the lower frame 4 and the bowl frames 5a and 5b, Between the both ends of the lower frame 4 and the lower ends of the collar frames 5a and 5b, a guide bracket (not shown) having a curved guide portion for changing the moving direction of the cover bands 25b and 25d by 90 degrees. Provide. The guide brackets for guiding the cover bands 25b and 25d related to the summoning rods 8a and 8b do not need a structure for maintaining the sealing property. In any case, the curved guide groove 50 and the opening portions at both ends of the curved guide portion are connected to the horizontal end opening of the guide groove 26a (26b) and the lower end openings of the storage portions 51a to 51d described later.

  Further, the heel-side airtight piece 49 includes a case portion 52 that can be fitted into the lower end portion of the butting ridge 9b, and an auxiliary hanging wall portion 53 extends downward from the indoor side of the case portion 52. The auxiliary hanging wall portion 53 is continuous with the hanging wall portion 24b in a state in which the case portion 52 is fitted into the lower end portion of the butting rod 9b and fixed to the butting rod 9b with a screw 54. That is, as described above, since the hanging wall portion 24b does not exist at the lower portion of the butting rod 9b at the end of the glass shoji 2b, the auxiliary hanging wall portion 53 is disposed at the lower portion of the butting rod 9b. Provided. The front end portion of the seal lip 28 of the guide member 27a elastically contacts the indoor side surfaces of the auxiliary hanging wall portion 53 and the hanging wall portion 24b. In addition, when the glass shoji 2b is moved to the closed position, a tip 55 that protrudes in a horizontal direction from the case 52 at a part of the auxiliary hanging wall 53 is an outdoor part of the frame lower side airtight piece 48. It closely faces the stepped portion 56 provided on the side surface through a minute gap. In the case of the present embodiment, such a structure closes a discontinuous portion between the horizontal end portion of each of the seal lips 28 and 28 and the lower end portion of the seal materials 33a and 33b, which exists in the lower corner portion. Yes.

  In the example shown in the drawing, the case portion 52 for accommodating a coupling bracket (not shown) for coupling one end portion of the cover band 25c to the lower end portion of the butting rod 9b in the heel side airtight piece 49. Is provided. The coupling bracket coupled to one end portion of the cover band 25c is coupled to the lower end portion of the butt bar 9b through the heel side airtight piece 49 in a state of being accommodated in the case portion 52. By configuring in this manner, the butted bar 9b can be sufficiently brought close to the rib frame 5b regardless of the presence of the coupling structure between one end of the cover band 25c and the lower end of the butted bar 9b. I have to. Various structures can be adopted for the structure of the coupling bracket that couples one end of the cover band 25c to the case 52. For example, one end portion of the cover band 25c is held down by a coupling bracket made of an elastic material such as synthetic resin, and the flange portions of the coupling bracket are engaged with both side edges of the opening notch 59 formed in the case portion 52. A structure is conceivable. However, since the structure of this part is not related to the gist of the present invention, illustration and description thereof are omitted.

  In the case of this embodiment, in order to provide the storage portions 51a to 51d for storing a part of the cover bands 25a to 25d, the frame frames 5a and 5b are respectively provided with the frame frame main bodies 57a and 57b. The inner brackets 58a and 58b are abutted and joined to the inner side surface of the inner surface. And a part of clearance gap between the inner surface of each of these collar frame main bodies 57a and 57b and these outer brackets 58a and 58b is made into said each accommodating part 51a-51d. The inner brackets 58a and 58b are not provided at the lower ends of the flange frame bodies 57a and 57b, and the lower portion of the frame-side airtight piece 48 or a part of the guide bracket is protruded from the lower ends. I guess. Then, the lower end opening of each of the storage portions 51a to 51d and the curved guide groove 50 or the upper end opening of the curved guide portion are brought into contact with each other, and each of the storage portions 51a to 51d and the curved guide groove 50 or The curved guide portion is continuous. With this configuration, the cover bands 25a to 25d can be transferred between the storage portions 51a to 51d and the curved guide groove 50 or the curved guide portion.

  In the case of the present embodiment configured as described above, if each of the glass shojis 2a and 2b is moved, the summing rods 8a and 8b and the butting rods 9a and 9b of the glass shojis 2a and 2b and the respective rod frames 5a. 5b, the cover bands 25a to 25d are transferred. The portions of the recesses 16a and 16b that are not covered with the lower collars 7a and 7b of the glass shojis 2a and 2b are covered with the cover bands 25a to 25d. That is, when each of the scissors 8a, 8b, 9a, 9b moves away from the opposing scissors frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the scissors 8a, 8b, 9a, 9b The cover bands 25a to 25d coupled to the portion are provided in the curved guide groove 50 portion or the guide bracket provided in the frame lower side airtight piece 48 from the storage portions 51a to 51d of the collar frames 5a and 5b.

The upper end openings of 16a and 16b cover the exposed portions between the lower end portions of the flanges 8a, 8b, 9a and 9b and the lower end portions of the flange frames 5a and 5b. In this state, in the upper surface of the lower frame 4, the appearance between the lower end of each of the flanges 8a, 8b, 9a, 9b and the lower end of each of the flange frames 5a, 5b is improved, and It is possible to prevent foreign matter from falling into the recesses 16a and 16b at the portion between them.

  In the case of the present embodiment, both side edges of the cover bands 25a to 25d, which are pulled out from the storage portions 51a to 51d and cover a part of the recesses 16a and 16b, are connected to the guides. It will be in the state latched by the grooves 26a and 26b. For this reason, it can prevent reliably that the both-sides edge of each of these cover belt | band | zones 25a-25d floats from the opening edge part of said each recessed part 16a, 16b. As a result, it is possible to effectively prevent fine foreign matter from getting into the recesses 16a and 16b and catching something on the cover bands 25a to 25d.

  On the other hand, when each of the scissors 8a, 8b, 9a, 9b approaches the facing scissors frames 5a, 5b as the glass shojis 2a, 2b move, the lower ends of the scissors 8a, 8b, 9a, 9b The cover bands 25a to 25d connected to the frame are provided in the curved guide groove 50 portion or the guide bracket provided in the frame lower side airtight piece 48 in the storage portions 51a to 51d of the flange frames 5a and 5b. The curved guide part is pushed in while changing the direction by 90 degrees. Each of the cover strips 25a to 25d has a property such as a metal tape measure and has a certain degree of rigidity in the pressing direction. Therefore, as the glass shojis 2a and 2b move, the storage portions 51a to 51d It is securely pushed into 51d.

  Between the both end portions of the lower frame 4 and the lower end portions of the respective saddle frames 5a and 5b, the butting rods 9a of the respective glass screens 2a and 2b in a state where the respective glass screens 2a and 2b are moved to the closed position. , 9b has a structure in which the cover bands 25a, 25c are moved between the lower frame 4 and the flange frames 5a, 5b. For this reason, as shown in FIG. 20 described above, the horizontal ends of the seal lips 28, 28 and the lower ends of the seal members 33a, 33b are discontinuous. It can be achieved by the side airtight piece 48, the auxiliary hanging wall portion 53, and the tip end portion of the seal lip 28 at the end portion of the guide member 27a facing the outer surface of the lower end portion of the butting rod 9a, 9b. For this reason, the airtightness and watertightness between the lower corner portions of the glass shojis 2a and 2b and the window frame 1 can be ensured.
