DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for floor covering at least one end of right and left buildings built through joints, which is formed integrally with one of the buildings and has a wall joint portion having a wall surface. Related to the device.

[0002]

2. Description of the Related Art Conventionally, a joint device for floors of this type has a joint plate for covering a joint portion and at least two or more pantograph-shaped link mechanisms for constantly positioning the center of the joint plate at the center of the joint portion. And a joint plate center maintaining mechanism using the above.

[0003]

The conventional joint device for floor uses a joint plate center maintaining mechanism using a pantograph-shaped link mechanism. Therefore, when a relatively lightweight joint plate is used, the joint plate is not used. Can be positioned at the center of the joint part as intended, but in the case of a joint plate that fills the mortar inside the dish-shaped joint plate body and fixes flooring materials such as tiles, the joint plate is heavy,
The joint plate center maintaining mechanism using the pantograph link mechanism has a drawback that the joint plate cannot be smoothly slid. Further, a joint using a support bar which is pivotally mounted at one end to a floor frame of one building and is slidably mounted at the other end to a rail mounted to the floor frame of the other building, and is disposed in an inclined state. By using the plate center maintenance mechanism, even a heavy joint plate can support the joint plate slidably, but when the joint part becomes wide or narrow, the joint plate changes in the front-back direction. There is a drawback that the sliding movement by half of the dimension causes a gap at the end, or the wall collides with and damages the wall.

The present invention has been made in view of the above-mentioned conventional drawbacks,
Provided is a floor joint device that can be used safely even when a heavy joint plate can be slid smoothly, and there is no gap at the end even if the joint portion becomes wide or narrow. It is intended to be.

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.
