DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention pushes up joints of floors, one of which is a wall, on the left or right, which is built through joints, and pushes up the joint plate when the joints become smaller in size. The present invention relates to a floor joint device that absorbs the swaying motion.

[0002]

2. Description of the Related Art Conventionally, in this type of joint device for floors, the other one of the joint plates is vertically movably mounted on a frame on the wall side, and one of the joint plates is fixed to a concave portion formed on the floor of one frame. It is supported by a fixture having an inclined guide surface formed on the side opposite to the joint.

[0003]

In the conventional joint device for floors, when the size of the joint portion is reduced, one of the joint plates rises along the guide surface of the fixing bracket and is inclined toward the floor surface side of one of the frames. When the center of the joint plate passes over the guide surface of the fixing bracket, the other joint plate moves upward by its own weight and becomes horizontal, so that one of the joint plates is guided by the guide surface of the fixing bracket. In a state where the joint plate is slid upward, almost one of the joint plates protrudes upward in an inclined state, and there is a disadvantage that there is a risk of injuring a pedestrian.

The present invention has been made in view of the above-mentioned conventional drawbacks,
When one of the joint plates slides up along the guide surface of the fixing bracket, the other joint plate can automatically move upward, and a floor joint device that allows pedestrians to travel safely is provided. It is intended to provide.

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.
