[Detailed description of the invention] (Field of industrial application) The present invention relates to a sliding door device used for shutters, doors, partitions, or so-called solarium sliding doors. Concerning the joint structure.

(Prior art) As shown in FIG.
~Slide the multiple door bodies formed on the inclined surface where the end faces c and d in the width direction of 5C are non-perpendicular to the door panel surface along a rail, etc., or move the door wheel or hanging wheel to the rail. We are developing a sliding door device that is configured to roll along the Such door body end faces c, d
The structure is such that when the door bodies are housed in the door body housing part (not shown), the end faces c and d rub against each other and easily overlap each other when the door bodies are housed in the door body housing part. This is for the purpose of Note that 27 is a connecting link for interlocking the door bodies, and 42 is a sealing material.

However, in this sliding door device, as shown in FIG. 10, when the guide roller 19 provided at the bottom of the door body 5A is rolled along the lower rail 3, the door Since the body 5A protrudes to the outside of the room, the upper and lower frames must be designed and structured to take this protrusion into consideration, which poses a problem in that the upper and lower frames become larger. Moreover, as shown in FIG. 11, the door bodies 5A and 5B in the door frame bending part 1x
Since the end faces c and d of the abutting portions are oriented in different directions, the sealing effect of the sealing material 42 is incomplete, resulting in a problem of poor air-water tightness.

(Problems to be Solved by the Invention) In view of the above-mentioned problems, the present invention is designed to prevent the door body from protruding toward the outside when the door body moves through the door frame curved portion, and to prevent the door frame from protruding from the edge of the door frame. It is an object of the present invention to provide a sliding door device which improves the air/water tightness at the abutting portions and which does not cause rattling of the door body during opening/closing operations and when the door body is in a stationary state.

(Means for Solving the Problems) The present invention forms a hook-shaped engagement shape at the end of the door body and connects adjacent door bodies in a detachable manner.
In the running section of the door body of the door frame, a plurality of door bodies are connected in a continuous manner and move along the upper and lower rails of the door frame, and the running section of the upper and lower rails has a curved section that curves at an obtuse angle. A guide is provided on at least one of the upper and lower sides of the engaging portion, and the upper rail or the lower rail of the door frame has a groove, and the guide is movably fitted into the groove, and the upper rail or the lower rail of the door frame has a groove. The width of the groove on one side of the lower rail divided by the curved part is made wider at the curved part by making it correspond to the interval between the guides when the guides of the adjacent door bodies are positioned at each groove position. It is characterized by being formed so that the width becomes gradually narrower as it moves away from the door frame, and the protrusion of the end of the door body at the bent part of the door frame is prevented, and the ends are butted together at the bent part of the door frame. Since the ends of the door body remain engaged, air and water tightness is maintained. Furthermore, in the present invention, the groove width of the groove-shaped upper rail or lower rail into which the guide is movably inserted corresponds to the change in the width of the moving door in the indoor and outdoor directions when two adjacent guides are combined. Accordingly, one side of the door frame curved part is wide and the width gradually becomes narrower as it goes away from the wide part, so that the engaging part is always engaged in a tight state and there is no play. This will further improve air and water tightness.

This connecting link 27 can move in and out of the groove 31b of the corner piece 31, and therefore, the interlocking mechanism 24 having the above configuration is able to reduce the thickness of the door body 5 in the door frame 1 by the groove 31b and the recesses 8a and 31a. It is now possible to pay within

The operation of this interlocking mechanism 24 will be explained as follows.
As shown in FIG.
When B and 5C are housed, the door body 5C
The connecting link 27 attached to is located on the side opposite to the door frame 1, and
is accommodated on the side opposite to the door frame 1 of the guide 21 of the door body 5C.

Here, when the door body 5C is first moved in the direction of the door frame 1 as shown by the arrow 40, the rolling element 25b at the tip of the connecting link 27 attached to the door body 5C is
It rolls along the guide 21 of the door body 5B, and the door body 5C
moves while the engaging portions 50 and 51 remain engaged with the door body 5D ahead. Then, the moving rolling element 25
When b comes into contact with the end of the guide 21 of the door body 5B,
The door body 5B is pulled through the connection link 27 and pulled out from the door body housing part 4, and the engaging part 51 of the door body 5B is pulled out.
engages with the engaging portion 50 of the preceding door body 5C and moves toward the door frame 1 side. That is, as shown in FIG. 4, when the door body 5C is moved in the direction of the arrow 40,
The adjacent door body 5B is moved by arrow 43 from the position shown at P.
, the engaging portion 51 rubs along the inner curved portion a of the engaging portion 50 of the door body 5C, and as shown by the solid line, the engaging portions 50 and 51 engage with each other, and the lower The door body 5 moves while the guide roller 19 rolls along the lower rail 3 provided on the frame 1b.

When the door bodies 5A to 5E are closed as shown in FIG. 2, the engaging portions 50 and 51 of adjacent door bodies engage with each other in the straight portion of the door frame 1, as shown in FIG. Therefore, not only is air/water tightness good, but also the engaging parts 50 and 51 can maintain a mutually engaged state even in the curved part 1x, as shown in FIG. Therefore, air and water tightness can be improved also in the door frame curved portion 1x.

In addition, as shown in FIGS. 4 and 5, the door body 5
The guide rollers 19 of B and 5C are the engaging parts 50 and 51
Guide roller 1 of the door body provided in and adjacent to the door body
Since the guide rollers 19 roll along the lower rail 3, the guide rollers 19 are always in close proximity to each other, and the engaging portions 50 and 51 are forced together. Since the door bodies 5B and 5C move while being engaged with each other,
The engaging portions 50 and 51 do not protrude toward the outdoors. Furthermore, since the outer shape of the engaging portion 51 is formed into an arcuate curved shape b, compared to the sharp shape having the inclined surfaces c and d shown in FIG. The width becomes smaller.

In addition, the groove width of the lower rail 3 into which the guide roller 19 is movably inserted is adjusted according to the change in the width in the indoor/outdoor direction of the combination of the two adjacent guide rollers 19, 19 of the moving door body 5. Since one side of the door frame curved portion 1x is wide and the width gradually becomes narrower as it goes away from the wide portion, the engaging portions 50 and 51 can be positioned in either the straight portion or the curved portion. Regardless of the position, the engaging portions 50 and 51 are always engaged in a close contact state, eliminating looseness and further improving air/water tightness.

When all the door bodies 5 are housed in the door body accommodating part 4 from the state of the building opening, that is, the door frame 1, the door bodies 5 are accommodated in the door body accommodating part 4 one on top of the other by the reverse operation to the above. In this case, while the door body 5 runs on the door frame 1, the door body 5 moves with the engaging parts 50 and 51 engaged, and the door roller 6 moves from the upper rail 2a to 2a' and from 2b'' to 2b. When moving to ', the door body 5 is guided by these rails, so that
The engaging portions 50 and 51 move in the opposite direction of the arrow 43 in FIG. 4 and separate, and the door bodies 5 are overlapped.

The present invention has been described above with reference to examples, but when implementing the present invention, a door roller is attached to the lower part of each door body 5 so as to be rotatable about the vertical axis for installation, and the door roller is attached along the groove-shaped upper rail. A guide roller attached to the upper part of the engaging parts 50, 51 may be fitted in a rotatable manner, or guides may be provided above and below. Furthermore, when the interlocking mechanism 24 is provided,
A structure in which the door is automatically opened and closed by a motor or the like, or a mechanism in which the door body is interlocked by pulling a string or chain, like a curtain opening and closing mechanism, can also be adopted. Further, in the present invention, it is also possible to provide an appropriate sealing material at the end. Further, instead of the guide roller 19, a guide made of a sliding member such as a rod may be used.

(Effects of the invention) As described above, in the present invention, a hook-shaped engagement part is formed at the end of the door body to releasably connect adjacent door bodies, and the door frame of the door frame is In the running part of the body, a plurality of door bodies are connected in a continuous manner and move along the upper and lower rails of the door frame, and the running part of the upper and lower rails has a curved part that curves at an obtuse angle. , a guide is provided on at least one of the upper and lower sides of the engaging portion, the upper rail or lower rail of the door frame has a groove, and the guide is movably fitted into the groove, and the upper rail or the lower rail of the door frame has a groove. The width of the groove on one side divided by the curved section is made to correspond to the distance between the guides when the guides of the adjacent door body are located at each groove position, so that the groove width becomes wider at the curved section and gradually becomes wider as it moves away from the curved section. Because it is formed to have a narrow width, when opening and closing the door, the ends are forcibly engaged with each other.
Protrusion of the end of the door body at the bent portion of the door frame is prevented. Therefore, there is no need for the door frame to protrude toward the outside, and the door frame can be made smaller. In addition, the ends of the door bodies that butt together at the straight part of the door frame are not only kept in an engaged state, but also at the curved part of the door frame. The width of the groove on the upper or lower rail is widened on one side of the curved part of the door frame, depending on the change in width in the indoor/outdoor direction when the two adjacent guides of the moving door body are combined. Since the width becomes gradually narrower as it moves away from the wide part, the ends are in close contact with each other regardless of whether the ends are in a straight part or a curved part. They are engaged, eliminates looseness, and provides high air/water tightness.
