Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint device for floor covering a joint between right and left floor frames provided via joints.

[0002]

2. Description of the Related Art Conventionally, this type of joint device for floors has a joint plate having a width twice as large as that of joints, and a rear end of the joint plate is rotatably mounted on a floor frame on one joint side. When the slope at the tip is narrowed, the joint is configured to be slid upward along the slope of the joint plate storage recess formed in the floor frame on the other joint side.

[0003]

In the conventional joint device for floors, if the other floor frame on the tip end side of the joint plate does not have a space for moving the joint plate having a width twice as large as that of the joint, the width of the joint is reduced. However, there is a disadvantage that the expansion and contraction movement cannot be absorbed.

The present invention has been made in view of the above-mentioned conventional drawbacks,
If there is a space approximately equal to the width of the joint from the end of the joint, it is possible to absorb the expansion and contraction movement of the width of the joint and reliably prevent the opening of the joint from being defective. It is an object of the present invention to provide a floor joint device that can be used.

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 merely for explanation and do not limit the technical scope of the present invention.

[0006]

Means for Solving the Problems In order to achieve the above object, the present invention relates to a method in which the joint part becomes wider due to an earthquake or the like in one of the right and left floor joints provided via the joint part. A slide joint plate capable of sliding to cover the joint portion, and a joint end portion side end portion of the slide joint plate in a stored state in which a lower end protruding outward is supported at a front end portion, and a rear end portion is supported. Covers the fixed joint plate attached to the floor joint on the other joint side of the left and right floor joints, and the upper part of the sliding joint plate in the housed state. A movable joint plate that is pushed upward by the pressing pressure of the plate, and automatically engages with an engaging portion formed at the tip of the slide joint plate when the joint portion is widened,
When the joint portion becomes narrow, the engagement with the engaging portion is automatically released, and the joint piece attached to the lower end of the fixed joint plate constitutes a joint device for floor. .
