Description

  The present invention relates to a floor joint device that covers a joint portion between left and right floor housings where a load is applied or a vehicle can travel at a portion having a side wall.

Conventionally, this type of floor joint device is formed in a joint plate support concave portion formed in one joint portion side floor housing of the left and right floor housings, and in the other joint portion side floor housing corresponding to the joint plate support concave portion. A plurality of joint plates arranged in parallel with no gaps so as to cover the joint plate slide support recesses and the joint plate support recesses. A locking pin insertion case formed at a portion near both sides of the rear end portion of the plurality of joint plates so that the front end portion of the joint plate can be moved in the vertical direction, and inserted into the locking pin insertion case. And mounting means comprising locking pins fixed to the floor frame of the joint plate supporting recess.

For this reason, if there is a side wall at one or both ends of the joint plates, the end plate of the joint plate becomes unsightly, but the joint on the side wall on the floor frame side where the tip of the joint plate is located If the through-hole which passes when the plate moves in the front-rear direction is not formed, the side wall or the joint plate is damaged.
Moreover, there existed a fault that it cannot be used in the place which cannot project an edge part joint plate from a side wall.
Japanese Patent No. 3880408

    In view of the above-mentioned conventional drawbacks, the present invention absorbs the swinging motions of the left and right floor frames in different directions in the front and rear directions without damaging the side walls and joint plates without forming unsightly through holes, and the swinging motion is stopped. Then, it aims at providing the joint device for floors which can be automatically returned to the original state.

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.

In order to achieve the above object, the present invention provides a joint plate supporting recess formed in a joint side floor housing of one housing and a joint joint side floor housing of the other housing corresponding to the joint plate supporting recess. A joint plate slide support recess formed on the inclined surface on the side of the plate, and one housing and the other housing are supported in the joint plate slide support recess and the joint plate support recess so that the joint portion is narrowed in the left-right direction so that the joint portion is narrowed. In a floor joint device using floor joint plates that are mounted in parallel with no gap so that the tip part slides on the joint plate slide support recess and can be rotated upward when swung The end joint plate side of the joint plate adjacent to the side joint plate contacting the side wall of the one housing and the side wall of the other housing can be rotated upward. It is supported and formed on an inclined surface, and an end portion of the end joint plate on the side of the adjacent joint plate is formed on the inclined surface so that the adjacent joint plate can be pushed up, and the rear end of the end joint plate A slide moving mechanism is provided between the joint plate supporting recess so that the part can be slid in the front-rear direction, and the end joint plate is always in contact with the side wall of the one housing and the side wall of the other housing. An end joint plate biasing means for biasing is provided to constitute a floor joint device.
