The problem to be solved by the present invention is to provide a structure which has a load bearing capacity of a mounting rail of a window stay, strength, airtightness of opening and closing of a window, and functional stability.

[0004]

As means for achieving the above object, the mounting rail of the window stay is extended on both sides in the longitudinal direction so as to have an inverted L-shaped cross section, and is fitted into the extended both side rails in the extended recess. A slider provided with a fitting groove is fitted therein, and a metal reinforcing plate and a connecting small arm provided on the lower surface of the slider are provided so as to be fixed with mounting pins via the slider. And a connecting portion on which a roller is mounted is provided on a connecting small arm pivotally connected to a slider of a mounting rail of a window stay, so that the roller is engaged with and disengaged from a recessed portion of a stopper provided on the stay mounting arm. It is the gist of the provision.

[0005]

In the window stay, a mounting rail is fixed horizontally to a lower frame of a window (not shown), and a slider fitted to a fitting concave portion formed by an inverted L-shaped rail provided on both sides of the bottom surface of the mounting rail. It is mounted in a slide shape, and a connecting small arm is mounted between the slider and the sliding arm.The mounting arm of the sliding door has a structure in which an auxiliary arm is mounted on a mounting rail. Since both are connected by a pivot pin, if the mounting arm of the shoji is opened forward of the mounting rail with respect to the mounting rail, the sliding arm attached to the mounting rail through the connecting small arm is used as the sliding arm in FIG. When sliding the sliding door to the right, the sliding door opens to the left and right in front of the window frame, and when the sliding door is closed, the sliding door is slid left in FIG. 1 to the auxiliary arm to the left on the mounting rail, the connecting small arm to the right, And the sliding arm is heavy Rollers attached to projections of the connecting small arms are folded and the windows sealed fit engaged with the recessed hole of the stopper attached to the mounting rail drawings right end, to close the sliding door.

[0009]

According to the present invention, there is provided a window stay device having the above-described structure, wherein the stay mounting rail is configured not to have a single-sided inverted L-shaped rail but to have both sides raised in an inverted L-shaped configuration, and a slider is provided between the rails. And a metal reinforcing plate is mounted on the lower surface of the slider, and the metal reinforcing plate and the mounting pin of the connecting small arm are caulked and fixed via the slider 15 to form a mounting structure. Therefore, it is useful for strengthening the connection structure between the mounting rail, the connecting small arm, and the sliding door mounting arm, and at the same time, the floating phenomenon of the slider from the mounting rail is eliminated, and the synthetic resin slider is heated in a fire or the like. Since the metal reinforcing plate fixed by caulking to the connecting small arm even if it is melted is longer than the space between the rails 11a and 11b on both sides of the mounting rail, it is held in the concave portion. The difficulty of the stay has been resolved, and the stability of the stay device and the load bearing strength have been doubled. Also, when closing the sash of each arm, when the arms are folded and overlapped, the rotating roller provided on the projecting part of the connecting small arm is smoothly inserted into the concave part provided on the stopper, so that the same part is consumed by the roller. There is an advantage that the window stay device can be locked and released to the mounting rail with a light operation by being reduced by the rotation.
