Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover device such as a ceiling for covering a joint part of a ceiling portion of a corridor, a veranda or the like having a wall surface on one side surface of a left and right building built through a joint part.

[0002]

2. Description of the Related Art Conventionally, a cover device such as a ceiling of this type is
A joint cover that covers the joints of the ceiling part is fixedly attached to the left and right frame parts of the ceiling part, and the other is slidably attached, or the front and rear directions that differ depending on the earthquake on one side wall of the left and right buildings If a swaying motion occurs, form a recess that can absorb the swaying motion,
One of the joint covers is fixedly attached to one of the skeletons, and the other is slidably supported so as to be inserted into the recess.

[0003]

The conventional cover device for a ceiling or the like cannot absorb the swaying motion when the left and right buildings sway in different front-back directions due to an earthquake or the like.
There is a drawback that a recess must be formed on at least one side wall surface to enable absorption.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
Even if the left and right buildings sway in different front, rear, left and right directions, it is possible to absorb the sway and prevent damage, and to provide a cover device such as a ceiling that can automatically return to the original state when the sway stops. Has an aim.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

At least two or more slide support bars 11 and 11 in which 10 and 10 are slidably supported and arranged in an inclined state, and at least two or more slide support bars 11 and 11 are respectively pivoted at substantially central portions. It is configured with a suspension bar 13 pivotally supported by the support pins 12, 12.

As shown in FIG. 5, the joint cover 6 has a plate-like joint cover main body 14 whose both ends are located on the ceiling surface on the side of the joint portion and covers the entire joint portion of the ceiling portion. The cover main body 14 is composed of mounting portions 15, 15, 15, 15 formed by bending the ends of the cover body 14 in a U-shape.

As shown in FIG. 6, the mounting member 5 is inserted into the joint cover 6, and both ends are provided with screws 16 and 1 on the side surfaces or upper surfaces of the mounting portions 15 and 15 at the left and right ends.
It is composed of a mounting bar 17 fixed by 6 and a mounting piece 19 fixed by a screw 18 to the suspension bar 13 of the central maintenance mechanism 4 fixed at a substantially central portion of the mounting bar 17.

As shown in FIG. 7, one end of the urging mechanism 7 is attached to the suspension bar 13 of the central maintenance mechanism 4, and the other end of the urging mechanism 7 is farther than the wall surfaces 3a and 3a of the left and right buildings 3,3. The urging spring 20 is attached to one wall surface 3c on the joint side of the inner portion.

In the cover device 1 for a ceiling or the like having the above structure, the central portion of the joint cover 6 is located at the central portion of the joint portion 2 by the central maintaining mechanism 4, and the joint cover 6 is provided by the urging mechanism 7.
The one side portion is always urged so as to always contact the wall surfaces 3a, 3a of the left and right buildings 3, 3.

In this state, when the left and right buildings 3, 3 sway in different left and right directions due to an earthquake or the like, as shown in FIGS. 8 and 9, at least two slide support bars 11, 11 of the central maintenance mechanism 4 are shown. Slides on the guide rails 9 and 9 to absorb the swaying movement, and when the slide support bars 11 and 11 slide, the suspension bar 13 is supported in a substantially central portion of the joint 2. Therefore, both ends of the joint cover 6 and the left and right skeletons 3b and 3b of the ceiling portions of the left and right buildings 3 and 3 slide and absorb the shaking motion.

When the left and right buildings 3, 3 sway in different front-back directions, the joint cover 6 is resisted by the wall surface 3a of one of the buildings 3 against the urging force of the urging mechanism 7, as shown in FIG. It is pushed out. At this time, the slide support bars 11, 11 of the central maintenance mechanism 4 slide on the guide rails 9, 9 to allow the joint cover 6 to slide. When the swaying motion is stopped, the joint cover 6 is automatically returned to its original position by the urging force of the urging mechanism 7.
