Description

Automatic locking device for Sliding Window with Locking Confirmation Function}

The present invention relates to an automatic locking device for sliding windows that automatically locks and locks a window with a window frame by the operation of closing the window, and unlocks the window by rotating the window handle to open the window, In more detail, it relates to an automatic locking device for sliding doors and windows with a locking confirmation function that can visually check the automatically locked state when the window is closed.

In general, a sliding window such as a balcony window is a method of opening and closing the door in a sliding manner by installing the window on the window frame in a straight line.The automatic locking assembly is installed on the sliding window, and when closing the window, a locker installed on the window side is installed on the window frame. It is automatically locked by being locked by the striker installed on the side, and when the window is opened, the locker is unlocked from the striker of the window frame and the window is opened by rotating a predetermined angle in the direction of opening the window handle.

The automatic locking assembly of such an automatic locking device for sliding doors is well known through the'automatic locking device for sliding doors' of the Korean Utility Model No. 20-0478262.

However, in the automatic locking assembly of the automatic locking device for sliding doors as described above, since the window is locked, that is, the locker on the window side is held and held by the striker on the window frame side, the locked state cannot be visually confirmed. There is anxiety about it, and for this reason, users have to check whether the window is opened by pushing the window directly toward the opening direction after closing the window to check the locked state.

Conventionally, in order to solve the above problems, for example, a handle assembly for windows and doors provided with an open/close mark of Korean Patent Registration No. 10-2003113 (hereinafter referred to as “prior art”) is known.

In the prior art, a sliding member marked'open and locked' is installed on the handle portion, and the rotational motion of the handle shaft coupled to the driving gear of the automatic locking assembly is converted into a linear reciprocating motion of the slide member to open or The locking is configured to be selectively displayed, and the hooks that are locked or unlocked by the drive gear of the automatic locking assembly and the striker of the window frame are configured to be interlocked by a rod and a stopper installed between them.

Therefore, when the window is opened and closed, the handle shaft rotates by a predetermined angle, and the slide member is interlocked to switch the open or locked display, whereby the user can directly check the open and locked state of the window.

However, in the configuration of the prior art as described above, when the handle is rotated to open the window while the hook is locked to the striker, the rotation of the handle shaft is linked to the stopper through the drive gear and the rod to unlock the hook. , The rotation of the handle shaft can be displayed by switching from'locked' to'open' by interlocking the sliding member.However, when the hook is automatically locked to the striker by closing the window, only the stopper is linked to the hook to move elastically. , The rotation of the handle shaft and drive gear and the interlocking of the rod do not interlock with the automatic locking operation of the hook.

Therefore, the sliding member is linked to the rotation of the handle shaft even when the stopper is not operating properly or the window is not completely closed and the hook is not securely locked to the striker, so the display is displayed by switching from'open' to'locked'. There is a problem that the safety and reliability, which is the most important thing in security windows, is degraded because it can be mistaken for the window to be locked.

In addition, in the prior art, since the sliding member is interlocked by the rotation operation of the handle shaft, even if the hook is in the state of the'open' indication of the window unlocked from the striker, even if the rotation operation of the handle is repeated without closing the window,'open' or Since the'locked' indication can be repeatedly switched, there is an undesirable problem in terms of quality.

Therefore, the interlocking member 52 of the locking means is able to continuously position the first end portion 52a on the second support surface 34c of the slider 34, and thus, the display hole of the handle body 20 ( 51), it is possible to continuously maintain the opening display portion 53b, and when the window is open, the slider 34 does not operate even if the window handle 10 is operated in the forward or reverse direction, and thus the opening display is locked. There is no change to display.

Subsequently, when the user closes the window, the locker 33 is pushed to the striker S and rotates while the window approaches the window frame W2 as shown in FIGS. 6A and 7A. At the same time, the slider 34, which was hung on the locker 33, is moved toward the locking position, that is, the rotating body 32 by the elastic force of the compression coil spring 35, and in this process, the locking jaws of the locker 33 ( Since 33a) is caught and held by the slider 34, the locker 33 can be kept locked to the striker S, and the locker 33 must be accurately moved to the locking position so that the locker 33 is moved to the striker (S). You can surely keep the locked state.

In this way, when the slider 34 moves to the locking position, the interlocking member 52 of the locking confirmation means is the first support surface from the second support surface 34c of the slider 34 as shown in FIG. 6(a). Since the first end 52a is positioned as 34b), it rotates from the open display position to the lock display position around the rotation support shaft 52c as in Fig. 7 (a), whereby the second end ( The locking display portion 53a of 52b) is exposed to the outside through the display hole 51.

As described above, the locking means of the present invention is operated in conjunction with the slider 34 interlocking with the locker 33 of the automatic locking assembly 30 that substantially performs the locking function of the window, and the slider 34 must be accurately operated. Since the locking state of the locker 33 is securely achieved, the lock indication can be displayed only when the window is securely locked, that is, the locker 33 is securely locked to the striker S, and thus the user is locked. By visually checking the markings, you can rest assured that the window is securely locked.
