Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a joint cover device that is installed between the frames of two adjacent buildings and covers the gap between the frames. (Prior Art) This type of joint cover device has already been devised by the same applicant, as disclosed in Japanese Utility Model Publication No. 58-38807. In this case, first and second bodies are rotatably attached in a cantilevered manner via cover attachment bodies (both first and second coupling bodies) to a pair of fixed bodies fixed to both body surfaces. The structure is such that the tip sides of both cover plates of No. 2 are overlapped by a predetermined amount. (Problems to be Solved by the Invention) In the conventional device described above, the amount of expansion and contraction in the left-right direction by both the first and second cover plates is limited to a relatively small range. That is, when both the frameworks move in the left-right direction and the gap between these frameworks widens greatly, a problem occurs in which the overlapping portions of both the first and second cover plates come off. Further, when the gap between the two bodies is reduced to a small size, the tips of the first and second cover plates collide with the cover mounting body, causing a problem that they are damaged. (Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a pair of fixed bodies fixed to the frame surfaces of both adjacent buildings through a cover attachment body. The left and right side cover plates are each attached in a cantilevered manner at their base sides, and among the both side cover plates, a folded piece is formed at the tip of one side cover plate bent toward the front side, and the other side cover plate is bent toward the front side. A folded piece bent toward the back side is formed at the tip of the side cover plate, and between the both side covers, an intermediate cover plate is overlapped by a predetermined amount with respect to the both side cover plates, and Engagement pieces are disposed movably with both the front and back surfaces in contact with the tips of the folded pieces, and at both ends of the intermediate cover plate in the width direction, engagement pieces face the folded pieces so as to be able to come into contact with and separate from them. are respectively formed, and a support mechanism for holding the intermediate cover plate at a substantially central portion between both the cover attachment bodies is disposed between the both cover attachment bodies, and the support mechanism is arranged between the both cover attachment bodies. Consisting of a four-section parallel link mechanism installed between the bodies, a support plate is attached to the center of a support link rod whose ends are pivotally connected to the longitudinal center of both opposing link rods of the parallel link mechanism. and the intermediate cover plate is attached to the support plate.

[Action/effect]

Therefore, in the present invention, when both the main bodies move in the left-right direction, the intermediate cover is held at the approximate center between the two cover attachment bodies by the holding mechanism, and both covers follow the two main bodies. The left and right cover plates expand and contract together with the mounting body. That is, from the maximum extension width where the folded pieces of the left and right cover plates come into contact with the engagement pieces at both ends of the intermediate cover plate, to the entire width of the intermediate cover plate,
The left and right cover plates can extend and contract with respect to the intermediate cover plate until the minimum reduced width is reached when the left and right cover plates are overlapped with each other. As a result, even if there is a large fluctuation in the left-right direction of both the frames, the gap between these frames can be satisfactorily covered by the intermediate cover plate and the left and right side cover plates. (Example) An example of the present invention will be described below with reference to the drawings. The frameworks (mainly exterior walls) of both adjacent buildings 1,
