Description

  The present invention relates to a ceiling joint device that covers joint portions of ceiling portions of left and right buildings provided via joint portions.

A conventional ceiling joint device is provided with a plurality of support bars at predetermined intervals on the left and right ceiling material fixing brackets, and a joint cover mounting bar is pivotally supported at a substantially central portion of the support bar. The joint cover is installed.

For this reason, when the left and right buildings are swung in different longitudinal directions, end joint covers that can be slidably moved at both ends must be installed to prevent damage to the ceiling joint cover. At the same time, a mechanism for always positioning the central portion of the plurality of support bars at the central portion of the joint portion is required, resulting in a disadvantage of high cost.
Japanese Patent No. 3,354,885

    In view of the above-mentioned conventional drawbacks, the present invention can absorb the shaking movement without damage even if the left and right buildings are swung in different front and rear directions, and the left and right joints so that the installation position does not move due to the shaking movement. It aims at providing the joint device for ceiling which can attach both ends to a side ceiling frame in the state of pivot support.

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 extends at least a pair of vertical directions with both ends pivotally supported at a position above the ceiling surface of the joint frame side ceiling frame of the left and right buildings provided via the joint. A pantograph-like load support link mechanism having three or more square frames and two or more central pivots, and left and right joint-side ceiling housings in the vicinity of the ceiling surface at the lower position of the load support link mechanism A pantograph-like ceiling material support link mechanism having the same configuration as the load support link mechanism, and a central pivot part of the ceiling material support link mechanism and the load support link mechanism. A plurality of suspension arms whose both ends are pivotally supported by the central pivot, and a tip portion whose rear end is pivotally supported by the central pivot of the ceiling material support link mechanism overlap each other to cover the ceiling joint. Multiple ceilings Constitute a ceiling for the joint unit in the ground cover.

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

(1) At least a pair of three or more quadrangular frames that extend and contract in the vertical direction, with both ends pivotally supported at a position above the ceiling surface of the joint frame side ceiling frame of the left and right buildings provided via the joint. The pantograph-shaped load support link mechanism having two or more central pivots, and both ends are pivotally supported by the right and left joint-side ceiling frame in the vicinity of the ceiling surface at the lower position of the load support link mechanism The pantograph-like ceiling material support link mechanism having the same configuration as the load support link mechanism that expands and contracts in the horizontal direction, and the central pivot portion of the ceiling material support link mechanism and the central pivot portion of the load support link mechanism have both ends. A plurality of suspension arms that are pivotally supported, and a plurality of ceiling joint covers that cover the ceiling joints by overlapping the tip portions pivoted at the rear ends of the central pivots of the ceiling material support link mechanism. It is configured Even if the left and right buildings swing differently, the load support link mechanism, ceiling material support link mechanism, and multiple ceiling joint covers move in the front-rear direction to absorb the swing motion and prevent damage. Can do.

(2) Since both ends of the load support link mechanism and the ceiling material support link are pivotally supported by the ceiling frame on the joint part side of the left and right buildings, the movement support by the shaking motion can be ensured. Can be prevented.
Therefore, when the shaking motion stops, the original state can be automatically restored.

(3) According to the above (1), since the structure is simple, it can be easily installed, and even if the joint portion becomes wide, it is efficient that the central portion of the joint portion is lowered by the suspension arm. Can prevent well.
Therefore, a plurality of ceiling joint covers can be installed in a substantially flat state, and the aesthetics can be improved.

(4) In claim 2, the same effects as in the above (1) to (3) can be obtained.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the present invention shown in the drawings.

In the first preferred embodiment for carrying out the present invention shown in FIGS. 1 to 7, reference numeral 1 denotes the ceiling of the present invention that covers the ceiling joints of the left and right buildings 3 and 3 provided via the joints 2.
