Description

  The present invention relates to a floor joint device that covers a space between right and left floor frames provided via joint portions.

  A conventional joint device that covers the left and right floor frame is configured to use a joint plate that is twice as large as the width of the joint portion, or to overlap and extend a plurality of joint plates sequentially.

For this reason, when a large joint plate is used, there is a drawback that the installation work is difficult and the cost is high.
In addition, the joint plates that are sequentially stacked have a drawback that a difference in height occurs at the beginning and end of the overlapping.

  SUMMARY OF THE INVENTION In view of the above-described conventional drawbacks, the present invention has an object to provide a floor joint device that can be used safely even when a large load is applied without causing a large step and without causing a large step. Yes.

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-described object, the present invention provides a left and right floor case provided through a joint part, the left and right rails fixed substantially horizontally to the left and right floor case body on the joint part side, and the left and right rails. At least two girder members that are slidably mounted at both ends in an inclined state, a central talc material that is pivotally supported by a pivot pin at a substantially central portion of the at least two girder members, A plurality of left and right talc woods pivotally supported by the at least two girder members at regular intervals between the talc wood and the left and right floor frames, and a substantially central portion of the at least two girder members are always jointed. Both ends positioned at a predetermined position of the central part of each part are supported by the pantograph-shaped telescopic link mechanism pivotally supported by the left and right floor frames, and the plurality of left and right talc materials and the central talc material, respectively. The center of these talc wood A joint plate having a width dimension of approximately one half of the joint plate, projecting outward from one end of the joint plate, and slidably moving on the adjacent joint plate. The joint device for floors is constituted by a plurality of joint cover bodies composed of the joint covers.

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

(1) The left and right floor frames provided via the joints, the left and right rails fixed almost horizontally to the left and right floor frames on the joints side, and both ends slidingly moved in an inclined state to the left and right rails At least two or more girders that can be attached, a central talc lumber pivotally supported by a pivot pin at the center of the at least two girders, and between the central talc lumber and the left and right floor frames A plurality of left and right talc members pivotally supported by the at least two or more girders at regular intervals, and a substantially central portion of the at least two or more girders at a predetermined position in the center of the joint portion at all times. The center portions of these talc materials, both ends of which are supported by the pantograph-shaped telescopic link mechanism pivotally supported by the left and right floor frames, and the plurality of left and right talc materials and the central talc material, respectively. Half the width between A plurality of joint covers comprising a joint cover projecting outward from one end portion of the joint plate and slidingly moving on the adjacent joint plate, and having a joint cover having substantially the same width as the joint plate. Therefore, the upper surface has a level difference corresponding to the thickness of the joint cover, and a large level difference does not occur.
For this reason, it can be used safely.
