Description

TECHNICAL FIELD The present invention relates to a sliding door device used for a shutter, a door, a partition, a so-called daylighting sliding door for a sunroom, and the like,
More specifically, the present invention relates to an engagement structure between door bodies.

(Prior Art) As shown in FIG. 7, the present inventors have formed end surfaces c and d in the width direction of the door bodies 5A to 5C on inclined surfaces that are non-perpendicular to the door panel surface. We are developing a sliding door device configured to slide a plurality of door bodies along a rail or the like, or to roll a door roller or a hanging vehicle along the rail. Such a structure of the door body end faces c and d has a structure in which the door body is housed in a door body housing portion (not shown).
This is because the end faces c and d rub against each other and are easily overlapped with each other when they are housed in the door body housing portion. Incidentally, 27 is a connecting link for interlocking the door bodies, and 42 is a sealing material.

However, in this sliding door device, for example, as shown in FIG. 8, in the bent portion 1x of the door frame 1, the door bodies 5A, 5B are formed.
Since the end faces c and d of the abutting portions are different in direction,
There is a problem that the sealing action of the sealing material 42 becomes incomplete and the air-tightness is poor.

Further, in Japanese Unexamined Patent Publication No. 50-52837, as shown in FIG. 9A, both ends of a strip-shaped sliding door unit 60 are bent in an arc shape to form a connecting portion 62 having a tear 61. The leading edge 62a of the connecting portion 62 at one end of the sliding door unit 60
There is disclosed a configuration in which the sliding door single bodies 60 are continuously moved by inserting the sliding doors 60 into the adjacent sliding door single bodies 60 through the cleft 61 and engaging them with each other.

However, when the connecting portion 62 has such a shape of the tear 61, the connecting portion 62 has a hollow shape.
When the two are connected, the intermediate portion 62 becomes the play at the tip portion, so that the play portion becomes loose, and wind and rain enters from that portion, so that the airtightness at the abutting portion of the end faces of the door bodies cannot be maintained. There was a problem.
Further, since the tip forming the tear 61 is in line contact, there is a possibility that the tip may be significantly worn depending on the member or the driving frequency, or that the tip may be impacted and deformed. In addition, since the connecting portion 62 is hollow, foreign matter such as dust is likely to enter the hollow portion, and particularly when adhesive foreign matter enters the cleft 61, it is difficult to remove. There is a problem that it is dangerous because it may be caught. In addition, since the connecting portion 62 has a hollow shape with the cleft 61,
As shown in FIG. 9 (b), in the curved portion such as the bent portion 63 x of the door frame 63, one hook-shaped head 6 of the connecting portion 62.
2b and the hook-shaped neck portion 62c of the other connecting portion 62 are caught by the looseness in the hollow portion, and the connecting portions 62, 62 are fixed to each other and do not rotate smoothly and are difficult to move.

(Problems to be solved by the invention) In view of the above-mentioned problems, the present invention improves air-tightness at the abutting portion of the end faces of the door bodies, and at the same time, strength, stability, and prevention of foreign matter from entering the connecting portion, An object is to provide an interlocking type sliding door device having an excellent structure in terms of smooth interlocking opening / closing operation.

(Means for Solving the Problem) According to the present invention, an engaging portion that engages with an adjacent door body in a disengageable manner is provided at an end portion in the width direction of the door body, and each engaging portion has a horizontal cross section. The shape has a rounded tip and a thick arcuate hook shape, and in the state where the engaging portions of adjacent door bodies are engaged with each other, the rounded tip circular arc surfaces are adjacent to each other. It is configured to be embraced by each other while being fitted to the arcuate inner surface of the engaging portion of the door body.

(Operation) In the present invention, the tip of the engaging portion of the door body has a rounded arc surface, and the tip arc surface of one engaging portion is the arc-shaped inner surface (concave surface) of the mating engaging portion. The surface contacts that are fitted together and contact each other without a gap are maintained not only when adjacent door bodies are linearly connected but also when they are connected at an angle. Further, the load applied to the door body is transmitted to the adjacent door body via this surface contact portion.
