Or it arranges so that it may contact. Accordingly, when the roller bodies 50b and 50b are slidably contacted with the opening and closing body 10 that opens and closes, the roller bodies 50b and 50b rotate along the opening and closing direction.

  The number of the pair of roller members 50, 50 arranged in the opening / closing body width direction can be single, but is preferably plural so as to suppress vibration of the opening / closing body 10 in the opening / closing body width direction. Furthermore, in order to obtain an effective vibration suppressing effect with the minimum necessary number of arrangements, a plurality of locations including one end side and the other end side of the opening / closing body width direction in the opening / closing body 10 are preferable.

  Further, the lintel member 70 has a pull-in / out port 70a for pulling the opening / closing body 10 to the take-up device 30 side or sending it from the take-up device 30 side on the top side, and opens and closes the draw-out port 70a.

According to the said structure, the roller member 50 removed in the case of repair, replacement | exchange etc. is once moved to the opening-and-closing body width direction after the decorative board 72 is removed, and is moved below (refer FIG. 4). ).
Therefore, the roller member 50 can be taken out without moving in the opening / closing body thickness direction, and even when the opening / closing body 10 is positioned between the two roller members 50, 50, replacement work of the roller member 50, etc. Can be performed well.

  The lintel member 70, the support convex portion 71, and the decorative plate 72 are provided over substantially the entire length in the opening / closing body width direction. However, the transportability of these portions and maintenance from the outside can be easily performed by partial attachment / detachment. In order to be able to perform, it is set as the aspect into which the full length of the opening-and-closing body width direction was divided | segmented as needed.

Next, operational effects when the opening / closing device A is opened and closed will be described in detail.
When the opening / closing body 10 is opened, the roller bodies 50b, 50b of the pair of roller members 50, 50 are in contact with the link portion 12 of the opening / closing body 10 while rolling, so that the opening / closing body thickness of the opening / closing body 10 is increased. Directional vibration is suppressed.
Further, the long shock-absorbing member 41 fed out from the reel device 40 is wound on the opening / closing body 10 wound around the winding shaft 31, so that the impact when the opening / closing body 10 is rolled up is alleviated.
Then, during the winding operation of the opening / closing body 10, the winding shaft 31 is opposite to the feeding side by the component force F <b> 2 of the diagonally downward force F <b> 1 in the opening / closing body 10 positioned in a suspended manner, as shown in FIG. 5. Move in the direction (right according to FIG. 5). Therefore, during the movement, the suspended portion of the opening / closing body 10 is maintained substantially vertical.

When the opening / closing body 10 is closed, the roller main bodies 50b, 50b of the pair of roller members 50, 50 are brought into contact with the link portion 12 of the opening / closing body 10 while rolling, in substantially the same manner as in the opening operation. The vibration in the opening / closing body thickness direction of the opening / closing body 10 is suppressed.
Then, the long buffer member 41 that has been wound around the winding shaft 31 together with the opening / closing body 10 is unwound from the winding shaft 31 together with the opening / closing body 10 and is wound around the reel device 40.
Further, during the unwinding operation of the opening / closing body 10, the take-up shaft 31 is moved to the unwinding side (FIG. 6) by the component force F 4 of the diagonally downward force F 3 in the opening / closing body 10 positioned in a suspended manner. To the left). Therefore, during the movement, the suspended portion of the opening / closing body 10 is maintained substantially vertical.

If the take-up shaft 31 moved as described above overruns a normal stationary position due to an inertia force or the like, the opening / closing body 10 around the take-up shaft 31 is brought into contact with the reel device 40. Therefore, the impact at the time of the contact is absorbed by the long buffer member 41 wound around the reel shaft 42.
At this time, the rotation direction of the take-up shaft 31 that feeds the opening / closing body 10 (counterclockwise in the illustrated example) and the rotation direction of the reel shaft 42 that takes up the long buffer member 41 (clockwise in accordance with the illustrated example). ) Is opposite, the impact is effectively mitigated as compared with the case where both the rotational directions are the same.

Furthermore, vibration when the opening / closing body 10 is wound up or drawn out, vibration of the drive source 33, vibration due to movement of the movable member 32, vibration of the power transmission mechanism that connects the drive source 33 and the winding shaft 31. Such vibrations associated with the winding operation and the feeding operation of the winding shaft 31 are alleviated by the plurality of elastic bodies 63 on each of the upper side and the lower side of the movable member 32.
Therefore, it is possible to reduce the vibration caused by the operation of the winding shaft 31 from being transmitted from the fixing member 60 to the housing q side and adversely affecting the housing q side.

  Next, the opening / closing device B as another preferred example will be described. In addition, in this switchgear B, about the same component as the switchgear A mentioned above, while using the same code | symbol, the detailed description which overlaps is abbreviate | omitted.

The opening / closing device B has a configuration in which the upper and lower guide portions 64, 64 in the opening / closing device A are replaced with a guide auxiliary member 65 having a shape in which these are integrated.
The guide auxiliary member 65 is formed by bending a substantially rectangular plate-like metal material on the upper and lower ends thereof to form reinforcement receiving portions 65a and 65a having a substantially concave cross section similar to the above-described reinforcement receiving member 64b. The rail 64a is fixed to the bottom of each reinforcement receiving portion 65a.
According to the opening / closing device B, the reinforcement receiving portion 65a and the rail 64a act substantially the same as the guide portion 64 described above, thereby guiding each wheel 32a in the opening / closing body thickness direction and removing the wheel 32a. To prevent. In addition, since the reinforcement receiving portions 65a and 65a that receive the rails 64a and 64a are connected and integrated, the deflection and deformation of each rail 64a can be more effectively suppressed, and the parallelism of the upper and lower rails 64a and 64a. As a result, the movable member 32 can be moved more smoothly.

The plurality of elastic bodies 63 may be a single elastic body that is continuous in the opening / closing body thickness direction (left and right direction according to FIG. 1). In order to effectively absorb the vibration associated with this, it is preferable to use a plurality of elastic bodies 63 arranged in the opening / closing body thickness direction as in the present embodiment.
That is, the vibration accompanying the operation of the winding shaft 31 includes a vibration component in the opening / closing body thickness direction and a vibration component in the opening / closing body opening / closing direction (vertical direction according to FIG. 1). Among these components, in order to effectively absorb the vibration component in the opening / closing body thickness direction, it is necessary to flexibly deform the elastic body 63 in the opening / closing body thickness direction. The shorter the body thickness direction, the more effective. Therefore, in a preferred example of the present embodiment, a plurality of elastic bodies 63 having a relatively short length in the opening / closing body thickness direction are arranged at predetermined intervals.
