Description

  The present invention relates to a wall surface joint device for covering a wall surface portion between left and right housings provided via a joint portion.

  This type of conventional wall joint device has a structure in which left and right cover plates are attached to a housing on the left and right joint portions side so that the tip portion can be rotated in the horizontal direction.

For this reason, at the time of a shaking movement such as an earthquake, there is a drawback that only a shaking movement having a dimension less than half the dimension of the joint between the left and right frames can be absorbed.
Patent No. 2914510

In view of the conventional drawbacks as described above, the present invention can absorb the swaying motion without damage even if the swaying motion is narrower than half the size of the joint between the left and right housings. An object of the present invention is to provide a wall joint device that can be used safely by preventing the occurrence of gaps at times.
Further, the present invention can effectively prevent the horizontal swing of the movable cover panel and satisfy the minimum and maximum expansion and contraction, and can be used for a wall joint device that can use a movable cover panel or a fixed cover panel having a minimum width dimension. The purpose is to provide.

The above and other objects and novel features of the present invention will become more fully 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.

  In order to achieve the above-mentioned object, the present invention is such that the tip part of the left and right casings provided via the joint part is attached to one joint part side casing via a hinge member so as to be rotatable in the horizontal direction. A frame having a width that is approximately a fraction of the width of the joint, and a horizontal joint through a hinge member on the other joint on the left and right of the left and right housings of the portion facing the mounting portion of the frame At least two or more pantograph-shaped expansion / contractions having at least one central support part pivotally supported at both ends so as to be parallel to the support part and the front end part of the frame body. A link, at least one intermediate strut pivotally supported so as to always maintain a vertical state at a central pivot portion of the at least two telescopic links, and the frame fixed to the frame A cover panel and the at least one or more At least one movable cover panel having a width of about twice the dimension between the central pivots, the rear end of which is fixed to the inter-column and the front end overlaps with the cover panel and the like, and the rear end of the column The wall surface joint device is constituted by a fixed cover panel having the same size as that of the movable cover panel, which is fixed and overlaps with the movable cover panel whose front end portion is fixed to the intermediate column adjacent to the column.

  As is clear from the above description, the present invention has the following effects.

(1) About the width dimension of the joint part of which the tip part was attached to one joint part side casing through the hinge member so that rotation was possible in the horizontal direction of the right and left cases provided via the joint part. A frame having a width of a fraction of the size, and the other joint part side frame of the left and right cases facing the attachment part of the frame are attached to the other side joint side case through a hinge member so as to be horizontally rotatable. A strut, at least two pantograph-shaped telescopic links having at least one central pivot that is pivotally supported at both ends so as to be parallel to the strut and the tip of the frame, and at least two or more At least one intermediate column that is pivotally supported so as to always maintain a vertical state at the central pivot of the telescopic link, a cover panel that is fixed to the frame and covers the frame, and the at least one The rear end is fixed to the above intermediate strut, At least one movable cover panel having a width that is approximately twice as large as the dimension between the central pivots, the end of which overlaps the cover panel, and the like. Because it is composed of a movable cover panel that is fixed to the adjacent intermediate strut and overlaps with the movable cover panel that is approximately the same size as that of the movable cover panel, The installation width ratio can be set to the minimum.
Therefore, it can be installed economically.

(2) According to the above (1), even when the left and right casings are swung so that the joint portion is enlarged, it is possible to prevent a gap from being generated between the cover panel, at least one movable cover panel, and the fixed cover panel. it can.
Therefore, it can be used safely.

(3) Since the frame is used according to (1), the length of at least two or more telescopic links can be shortened accordingly.
Therefore, it is possible to efficiently prevent the extension link from becoming long and becoming weak against the pressure in the front-rear direction as in the prior art.

(4) In claim 2, the same effects as in the above (1) to (3) can be obtained, and the support bar and the anti-swaying plate ensure that the at least two or more extension links sway in the direction perpendicular to the extension / contraction direction. Can be blocked.
Therefore, it is possible to efficiently prevent noise and damage caused by these vibrations.

(5) In claim 3, the same effects as in the above (1) to (3) can be obtained, and a cover panel, at least one movable cover panel and a fixed cover panel can be used with a minimum width, It can be installed more economically.
