Description

  The present invention relates to a floor joint device for covering with a floor joint plate using a shallow plate-shaped floor joint plate body in which the floor surfaces of the left and right housings having both side walls provided through joint portions are arranged in parallel. About.

  Conventionally, floor joint devices using shallow plate-like floor joint plate bodies installed on the left and right housings where the side walls are provided absorb the swinging motions of the left and right housings in different longitudinal directions. According to the present applicant, the end floor joint plate using the plate-shaped floor joint plate body is inserted into the adjacent joint plate or is lifted upward to absorb the shaking motion (Japanese Patent Application No. 2008- 156890).

  However, the floor joint device configured as described above requires a support rail that supports the rear end of the end floor joint plate so as to be slidable in the front-rear direction. There is a drawback that it is not easy to confirm the operation by moving the slide.

Japanese Patent Application No. 2008-156890

  In view of the above-described conventional drawbacks, the present invention does not require a support rail for slidably supporting the end floor joint plate and easily moves the movable floor joint plate attached to the end floor joint plate manually. An object of the present invention is to provide a floor joint device that can be slid in a direction and can easily check its operation.

  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.

  To achieve the above object, according to the present invention, the rear end is attached to one floor case of the part excluding the both side walls of the left and right cases having both side walls provided through the joint part, and the front end is the other side. A central floor joint plate using a shallow plate-shaped floor joint plate body that slides on the floor housing of the floor, and a rear end portion is attached to one floor housing so as to be located at both ends of the central floor joint plate, An end floor joint plate using a shallow dish-shaped end floor joint plate body in which the tip part slides on the other floor frame, and the tip part has a small width, and a rear end of the end floor joint plate The rear end portion is pivotally supported by one floor frame of the portion of the portion near the both side walls, or is pivotally supported by the portion of the end floor joint plate near the rear end portion, and the front end portion is on the other floor frame. Sliding, the tip has a large width dimension, and the end When the movable floor joint plate using a shallow dish-shaped movable floor joint plate main body that is substantially rectangular on the floor joint plate and the tip of this movable floor joint plate is pressed by the side wall of the other housing, A movable floor joint plate push-up means for guiding the movable floor joint plate onto the end floor joint plate; and a return means for returning the movable floor joint plate pushed up on the end floor joint plate to the original position. It constitutes a floor joint device.
