[0021]

16 to 22 show different embodiments of the present invention.
Hereinafter, different embodiments of the present invention will be described. In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and duplicate description will be omitted.

In the second embodiment of the present invention shown in FIGS. 16 to 19, the main difference from the first embodiment of the present invention is that the rear end is fixed to the corner of the joint plate 10. Fixed corner cover 4 whose leading end has a trapezoidal contour
0, and a pivot pin 41 is attached to the tip of the fixed corner cover 40.
And a movable corner cover 42 rotatably mounted on the corner cover body 19A, and pivotal pins 43, 43 are attached to both ends of the fixed corner cover 40 of the corner cover body 19A. In the point that the left and right side covers 21 are attached, even the floor jointing device 1A for corners configured as described above can obtain the same operation and effects as those of the first embodiment of the present invention.

The third embodiment of the present invention shown in FIGS. 20 to 22 is different from the first embodiment of the present invention mainly in that the inner portion of the joint plate 10 is The corner joint floor joint device 1B configured as described above may be configured so as to be rotatably attached to the frame 3. When the width of the floor joint 2 is relatively small, the inner portion of the joint plate 10 is attached to the inner frame 3 by the hinge member 44. When the floor joint becomes narrow, the inclination of the joint plate 10 is reduced. In this case, it is preferable to use a joint plate moving mechanism for automatically moving the inner part of the joint plate 10 upward in this case.

In the embodiment of the present invention, the center maintaining link mechanism 11 using the pantograph-shaped telescopic link 36 is used.
However, the present invention is not limited to this, and the center part of the joint plate can always be located at the center part of the floor joint part even if the floor joint part becomes narrow or wide. If it is a structure, it may be used as a center maintenance link mechanism.

[0025]

As apparent from the above description, the following effects can be obtained in the present invention.

(1) An inner supporting recess and an outer supporting recess formed so that the anti-floor joint side is inclined on the floor surface of the inner frame and the outer frame above the floor joint formed at right angles. A joint plate that covers the floor joints at portions other than the inclined surface portions of the inner support recess and the outer support recess, a center maintaining link mechanism that always positions the center of the joint plate at the center of the floor joint, and the joint plate An inner cover plate attached to a portion corresponding to the inner support concave portion so that a tip portion rotates vertically, and a tip corresponding to the outer support concave portion of the joint plate and excluding a corner portion. A vertical and horizontal outer cover plate attached so that the portion rotates vertically, and a pivot provided at a position near the rear end where a rear end is attached to a corner of the joint plate. Pi A corner cover body having a square notch formed on both sides at which the tip rotates vertically, and a rear portion of the corner cover body so as to cover the notches on both sides of the corner cover body. It consists of left and right side covers attached to the notch end near the end so that the tip rotates vertically by a pivot pin, so the corner floor joints shake due to earthquake etc. Even if it becomes wider or narrower, the joint between the joint plate and the floor surface of the inner skeleton and the floor surface of the outer skeleton is covered with an inner cover plate and an outer cover plate whose tips rotate vertically, It is possible to reliably prevent a concave portion where a foot is likely to be caught or a corner portion that is easily injured from protruding outward. Therefore,
Can be used safely.

(2) According to the above (1), when one floor joint of the corner is widened or the other floor joint is swung so as to be the same or narrow, the corner cover main body becomes the floor of the outer frame. While covering the concave portion of the corner portion on the surface, the tip of the side cover where the floor joint is wider is rotated while sliding along the inclined surface to be in an inclined state,
The opened concave portion can be reduced. Therefore, it is possible to efficiently prevent a foot or the like from entering the concave portion that opens, and to use the device safely.

(3) According to the above (1), the outer cover plate, the corner cover main body, and the side cover can be formed on the same surface, so that a step can be eliminated and the device can be used safely.

(4) Claims 2 and 3 also have the above (1) to (3).
The same effect can be obtained.
