Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint covering device for a wall covering a joint of a wall portion between right and left buildings built through joints. 2. Description of the Related Art Conventionally, a joint covering device for a wall surface using left and right joint covers for rotating a joint so that a central portion thereof projects forward when an joint becomes narrow due to an earthquake or the like has been considered. I have. [0003] Since the conventional joint cover device for a wall uses left and right joint covers each having a width half that of the joint, the front of the free ends of the left and right joint covers is used. There is a drawback that it cannot be used when there is an obstacle in front because the amount of protrusion to the front becomes large. The present invention has been made in view of the above-mentioned conventional drawbacks,
Even if the left and right buildings sway due to an earthquake or the like so that the joints become narrower, it is possible to prevent the turning joint cover from protruding greatly forward, and the turning joint cover flaps due to strong winds and noise. It is an object of the present invention to provide a joint covering device for a wall surface that can efficiently prevent the joint from coming out. The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention. [0006] In order to achieve the above object, the present invention provides a pair of fixing brackets fixed to the joint side wall of the left and right buildings built through joints. A pair of movable brackets attached to the pair of fixed brackets so as to be rotatable in the horizontal direction, an expandable and contractible center maintaining mechanism having at least two ends pivotally supported by the pair of movable brackets; A support bracket pivotally supported by a central pivot on the front side of the center maintenance mechanism or more, and a rear end is rotatably mounted on the pair of movable brackets covering the joint, and the joint is rotated by an earthquake or the like. A folding screen-like left and right joint joint cover with a pivoting bar attached so that the center part can protrude forward when it becomes narrow, and the free ends of the left and right joint joint covers contact the support bracket. A pair of free end biasing devices that urge against It constitutes a surface joint cover device.

It comprises a bearing portion 21 and the central support mechanism pivotal support portion 22 integrally formed at the other end of the front surface of the movable fitting main body 19. As shown in FIG. 6, the center maintaining mechanisms 7, 7 have a link mechanism 23 formed in a rectangular frame shape, and two opposite ends 23a, 23a of the link mechanism 23 at substantially the center of the opposed arms 23a, 23a. A central pivot bar 25 in which a central pivot portion 8 is formed in a central portion pivotally supported by pivot pins 24, 24, and pivot pins 26 at both ends of the link mechanism 23;
26, and mounting brackets 27, 27 pivotally supported by 26. As shown in FIG. 7, the right and left turning joint covers 13 are approximately one-fourth of the width of the joint portion 2.
Side joint cover 2 formed with shank portions 28, 28, both ends of which are formed in a slightly smaller width dimension than that of the first embodiment.
9 and one end formed to have approximately the same width as the side joint cover 29, a spherical-shaped shaft 28 is formed, and a support piece 30 is formed so as to protrude toward the back surface near the other end. A center-side joint cover 31 and a C-shaped bearing in which a shaft 28 of the side joint cover 29 and a shaft 28 of the center-side joint cover 31 are rotatably supported at both ends of a T-shape. The pivot bar 12 is formed with the parts 32 and 32. The pair of free end biasing members 14, 14 are shown in FIG.
As shown in FIG.
Coil springs attached to the free ends of the center-side joint covers 31, 31 of the pair 3, 13 and attached to the front end of the pair of movable fittings 6, near the other end via the support bar 11. A wire composed of a wire 34 on which a wire 33 is interposed is used. As shown in FIG. 9, the pivoting bar urging members 15, 15 have one end attached to the lower end of the pivoting bar 12 and the other end formed on the center maintaining mechanism 7. A member composed of a wire 37 provided with a coil spring 36 attached to the support bar 11 or a portion near the other end of the front surface of the pair of movable fittings 6, 6 via 35 is used. The joint cover device 1 for a wall surface having the above-described configuration normally includes a left and right rotating joint cover 1 covering the joint portion 2.
The free ends of the pair 3 and 13 and the pivot bars 12 and 12 are formed by the urging force of the pair of free end urging members 14 and 14 and the pivot bar urging members 15 and 1.
Because of the urging force of 5, the central pressing mechanisms 7, 7 are pressed against each other, so that the left and right turning joint covers 13, 13 can be prevented from generating noise even when strong winds strike. . When the right and left buildings 3 and 3 swing in different left and right directions due to an earthquake or the like and the joint portion 2 is widened, FIG.
As shown at 0, the left and right turning joint covers 13, 13 move in the left-right direction to absorb the swinging movement. During the movement in the left-right direction, the left and right turning joint covers 13, 13 also include a pair of free end urging devices 14, 14 and pivot bar urging devices 15, 15.
Urged so as to abut against the center maintaining mechanisms 7,7. When the joint portion 2 becomes narrow, the free ends of the left and right pivot joint covers 13, 13 abut against the support fitting 10, as shown in FIG.
The portion projects forward and is folded against the urging force of the pivot bar urging tools 15, 15 to absorb the swinging motion. When the left and right buildings 3, 3 swing in different front and rear directions, the pair of movable fittings 6, 6 rotate as shown in FIG. 12 to absorb the swing movement. In this case, when the joint portion 2 expands or contracts in size, the left and right turning joint covers 13 and 13 operate as described above to absorb the swinging movement. FIG. 13 to FIG. 25 show different embodiments of the present invention.
Hereinafter, different embodiments of the present invention will be described. In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and duplicate description will be omitted.
