Description

Turning type window with hand holding prevention function}

The present invention relates to a pivoting window equipped with a hand-trap prevention function, and more particularly, when a user opens a window, the window not only rotates and opens at a certain angle without a separate operation, but also effectively prevents the window from being arbitrarily closed, thereby improving usability. As this improves, the user's hands are prevented from being pinched, and as such, the present invention relates to a pivoting window equipped with a hand-jamming prevention function with improved safety.

In general, in recent years, as a type of system window, a tilt and turn type window has been used. Such a tilt-and-turn type window can implement a tilt function of opening an upper portion of a window mounted on a window frame in a semi-opened state and a turn function of opening and closing the window by rotating it in a horizontal direction. As shown in FIGS. 1 and 2, in the conventional tilt-and-turn window system, a window 5 is rotatably mounted in a horizontal direction to a hinge 3 coupled to one side of a window frame 2, and the window ( 5) A stay bar unit 500 for regulating the rotation angle is installed between the window frame 2 and the window 5.

And the stay bar unit 500 of the conventional window system includes a guide rail 510 installed in the longitudinal direction on the upper surface of the window frame 2, a hinge connecting rod 530 installed on the lower surface of the window 5, and a guide rail ( 510), a slider 540 that slides along, a stopper 550 that is slidably installed on the guide rail 510 on the side close to the hinge 3, and one end of which is a hinge connecting rod 530 It is hinged by the hinge pin 531 and the other end is configured to include a link bar 520 that is hingedly screwed to the slider 540 by the locking handle 560.

As shown in (a) of FIG. 2, the locking handle 560 guides the top of the threaded portion 561 screwed into the female threaded hole 542 through the through hole 521 formed at the outer end of the link bar 520. One side of the plate handle 562 having a predetermined length and a narrower width than the rail 510 is installed, and when the user opens the window 5 and rotates the lock handle 560 as shown in FIG. 2 (b), the lock handle As the threaded portion 561 of 560 is fastened to the female threaded hole 542 of the slider 540, the guide rail 510 and the slider 540 come into close contact and the slider 540 is fixed in position.
