However, sashes for cold regions are often made of plastic. Since the plastic sash has a high heat insulating property, it has the effect of suppressing the generation of dew condensation, but has the drawback of being inferior in rigidity to metal. For this reason, when the conventional locking mechanism using the Gremon lock is adopted for the vertical sliding window and the outside window using the plastic sash, for example, as shown in FIG. 8, the surface opposite to the surface exposed to the high radiant heat of the summer sun Deformation due to warpage occurs in the shoji 20 that has been opened due to the temperature difference between and It happened.

That is, in the conventional gremone tablet, although the grommet roller 24 and the glemmon receiver 25 provided near the central portion can guide the shoji in the direction of pulling it toward the closing side, deformation of the shoji itself is prevented. I could not correct it. In the case of a particularly large shoji, the amount of deformation was large, and the distance between the gremon roller and the gremon receiver on both ends was large, which was more serious.

In response to this, it has been considered to insert a metal core material into the hollow portion of the shoji to increase the rigidity.
However, it was not enough to prevent the shoji deformation.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a locking mechanism for a plastic sash that can be forcibly corrected and firmly closed even if the shoji deforms due to solar heat or the like.

It is arranged at both ends of the vertical frame 5 so as to correspond to 13c.

The third glemon receivers 10d and 10e have a guide piece 16 having the same structure as that of the first glemon receivers 10a, and are located on the center side of the second glemon receivers 10b and 10c (on the side of the first glemon receiver 10a). ) In the vicinity of both ends of the slide plate 9 corresponding to the Gremont rollers 13d and 13e.

It should be noted that the third glemon receivers 10d and 10e are provided.
The corresponding Gremont rollers 13d and 13e may be provided at positions where they can be engaged with each other at the time of maximum deformation when the shoji 2 is warped and deformed.

In the above-mentioned locking mechanism, when the sliding plate 9 is slid upward from the lower end position by the glemon handle 12 after closing the shoji screen 2, each of the glemon rollers also moves upward.
As shown in FIG. 5, a, 13d, and 13e are engaged with the guide pieces 16 of the first Glemon receiver 10a and the third Glemon receivers 10d and 10e, respectively, and along the guide surfaces according to the amount of sliding upward. While sliding on the central portion of the guide piece 16, the shoji 2 is guided to the closed side (indoor side). In this figure, the center lines of the shoji 2 at this time are shown by 2a, 2b and 2c. For this reason, the shoji 2 is pulled toward the closing side, and at the same time, the gremon rollers 13b and 13c at both ends are moved to the second gremon receiver 10.
