DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint device for a floor covering joints of floors of right and left buildings built through joints.

[0002]

2. Description of the Related Art In a conventional floor joint device, left and right channel-shaped fixing brackets fixed to floors on the joint side of right and left buildings, and portions near both ends are supported by the left and right fixing brackets. The joint cover includes a joint cover that covers the joint, and cover plates respectively attached to the left and right fixing brackets so as to cover upper portions of both ends of the joint cover.

[0003]

Since the conventional joint covering device for floors is covered with joint coverings in which portions near both ends are supported by left and right fixing brackets, when the left and right buildings are shaken by an earthquake, the left and right joints are left and right. Since the width of one of the fixing brackets is the maximum amount of movement, the amount of movement is small, and if the amount of movement is set large, the width of the floor joint cover device becomes large and disadvantageously large.

The present invention has been made in view of the above-mentioned conventional drawbacks,
If the building on the left and right swings due to an earthquake, etc., if it moves only to the width of the joint, it will move smoothly without any backlash following the swinging movement, and if the swing stops It is an object of the present invention to provide a floor joint device which can be smoothly moved and returned to an original state, has a simple structure, can be easily installed, and can be manufactured at low cost.

The foregoing and other objects and novel features of the 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.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a joint formed between joints on the floors of left and right buildings which are formed through joints so as to open to the joints. A pair of recesses, a pair of fixing brackets fixed to the pair of recesses, and a pair of fixing brackets whose inclined sides are inclined guide surfaces, and both side walls covering the joints and the pair of recesses are formed on inclined surfaces. A joint cover, a plurality of rollers attached to the bottom surface and both side walls of a portion corresponding to the pair of fixing brackets of the joint cover, and the pair of fixing brackets or the right and left building attached to the frame of the floor portion of the building. A floor joint device is constituted by at least two or more central maintenance link mechanisms in which a support rod attached to a central portion of the joint cover is pivotally supported on the central pivot portion so as to be vertically movable.
