Description

The present invention relates to a floor joint device that covers a joint portion between left and right floor frames capable of running a vehicle.

Conventionally, a floor joint device on which a vehicle can travel includes a joint plate support concave portion formed in one joint portion side floor housing of the left and right floor housings, and the other joint portion side floor housing corresponding to the joint plate support concave portion. A joint plate slide support recess having an inclined surface on the side opposite to the joint portion, a joint plate attached so as to cover the joint plate slide support recess and the joint plate support recess, and a tip portion of the joint plate in the vertical direction A locking pin insertion case formed at a position near both sides of the rear end portion of the joint plate, and fixed to the floor case of the joint plate supporting recess inserted into the locking pin insertion case. It was comprised with the attachment means which consists of a locking pin.

For this reason, when the joint plate is greatly shaken so that the joint portion becomes narrow due to an earthquake, the rear end of the joint plate moves upward, the locking state between the locking pin insertion case and the locking pin is released, and the rocking motion There is a drawback that the joint plate cannot be returned to its original state even if the operation stops.
JP2007-132157A

    In view of the conventional drawbacks as described above, the present invention ensures that the locking pin is removed from the locking pin insertion hole fixed to the joint plate even if the joint plate is greatly shaken so that the joint portion is narrowed by an earthquake. An object of the present invention is to provide a floor joint device that can be prevented automatically and automatically returned to its original state when the shaking motion stops.

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-mentioned object, the present invention is formed on the joint plate support concave portion formed on the joint portion side of one floor case and on the joint portion side of the other floor case corresponding to the joint plate support concave portion. A joint plate slide support recess formed on the inclined surface on the side opposite to the joint portion, and a joint plate having a rear end supported by the joint plate support recess and a front end supported slidably by the joint plate slide support recess. And a joint device for floors, the attachment means for attaching the rear end portion of the joint plate to the joint plate support recess so that the front end portion of the joint plate can be rotated in the vertical direction. A locking pin insertion case provided at a portion near the both sides of the rear end of the plate, and the tip of the joint plate can be rotated in the vertical direction into this locking pin insertion case. A locking pin fixed to the joint body of the joint plate support recess so as to enter in an inclined state so that it can be slidable and slidably movable in the locking pin insertion case fixed to the upper part of the locking pin. Floor joints with a pressing plate and a stopper piece that can turn the tip of the joint plate fixed to the inner wall surface of the locking pin insertion case in the vertical direction and can come into contact with the presser plate Configure the device.

  As is clear from the above description, the present invention has the following effects.

(1) Locking pin insertion case provided with attachment means near the both sides of the rear end portion of the joint plate, and the tip of the joint plate can be rotated in the vertical direction into this locking pin insertion case A locking pin fixed to the housing of the joint plate supporting recess so as to enter in an inclined state so as to be able to become, and a presser slidably movable in the locking pin insertion case fixed to the upper part of the locking pin so as to be detachable Because it is composed of a plate and a stopper piece that can turn the tip of the joint plate fixed to the inner wall surface of the locking pin insertion case in the vertical direction and can come into contact with the presser plate, Even if the joint part is swung so as to become narrow, the stopper piece fixed to the rear end part of the joint plate comes into contact with the presser plate fixed to the upper part of the locking pin to reliably prevent it from falling off. be able to.
Therefore, when the shaking motion of the earthquake stops, the joint plate can automatically return to the original state.
For this reason, even if an earthquake occurs, repair work is unnecessary, and the repair cost can be reduced.

(2) According to the above (1), the tip portion of the joint plate can be smoothly rotated in the vertical direction, and can be used as in the conventional case.
