A central portion where both ends are pivotally supported by pivot pins 27 and 27 at a substantially central portion of one link 26a and 26a opposite to each other. And a central maintenance bar 28 having a central pivot 23 is used.

In the joint device for ceiling 1B considered by the present inventor shown in FIGS. 13 to 15, the main difference from the second embodiment for carrying out the present invention is that the end portions of the joint ceiling material support bars 9A and 9A are end portions. By using the joint ceiling panel 11A in which five slide panels 10A, 10A, 10A, 10A, 10A not using the ceiling joint panel are slidably mounted in the front-rear direction, the joint ceiling panel 11A is used. The ceiling joint device 1B may be configured. In this case, since the end ceiling joint panel is not used, the structure is simple and it can be manufactured at low cost.
Further, even if the joint portion 2 becomes narrow and different back-and-forth swing motions occur, both ends of the slide panel 10A at the center of the slide panels 10A, 10A, 10A, 10A, 10A are the outer walls of the left and right buildings 3, 3. Since it will not be pressed unless it contacts the housings 3b and 3b, it can be slid smoothly to absorb the shaking motion.
In this case, the inclined portions of the outer wall joint devices 13 and 13 are provided at one end or both ends of the slide panels 10A, 10A, and 10A other than the portions that contact the outer wall housings 3b and 3b of the left and right buildings 3 and 3. By forming a gap so that it can be absorbed or by installing the end ceiling joint panel 17, it is possible to efficiently prevent the movement in different front and rear directions from being damaged or without causing a large gap.

  In the ceiling joint device 1C considered by the present inventor shown in FIGS. 16 to 19, the difference from the best first embodiment for carrying out the present invention is that the left and right ceiling material supports 5, 5 Projecting into the joint part 2 by approximately one third, and in the embodiment of the present invention, two pieces can be slid in the front-rear direction in the left and right ceiling material supports 5, 5 on the joint part side. In addition to mounting the slide panels 10, 10, 10, 10, the end portion on the joint portion side is formed into inclined surfaces 29, 29 that can be pushed upward when the joint portion is narrowed. The central ceiling panel 30 on which the part is supported is supported by the left and right ceiling material supports 5 and 5 with the slide support bars 7 and 7 via the suspension bars 8 and 8, and the slide support bars 7 and 7 as necessary. Inverted trapezoidal guide member 31 31, and guide pieces 32, 32 that can slide the side walls 31 a, 31 a of the guide members 31, 31 are attached to the left and right ceiling material supports 5, 5, and the central ceiling panel 30 is moved upward when the joint portion becomes narrower. The ceiling joint device 1 </ b> C configured in this way may be used in that the sliding movement of the ceiling is made smoother.

The second embodiment for carrying out the present invention shown in FIGS. 20 to 22 is mainly different from the best first embodiment for carrying out the present invention in that four pairs of supports to which rollers 33 are attached are supported. In the point that the joint ceiling panel 11B using the metal fittings 16A and 16A is used, even the ceiling joint device 1D configured using such a joint ceiling panel 11B is the best first for carrying out the present invention. The effect similar to that of the first embodiment can be obtained, and the slide panels 10, 10, 10, 10 can be slid in the front-rear direction more smoothly by the four pairs of support fittings 16A, 16A to which the rollers 33 are attached.
Note that the support bracket 16A to which the roller 33 is attached can be used in the second embodiment as well.
