Description

Handle Assembly for Sliding Window with Locking Confirmation Function}

The present invention relates to a handle assembly for a sliding window that allows a window to be automatically locked and locked to a window frame by a window closing operation, and to open a window by releasing the locked state by operating a window handle to open the window. The present invention relates to a handle assembly for sliding doors and windows equipped with a lock confirmation function that allows you to visually check the automatically locked state when the window is closed.

In general, a sliding window is a method of opening and closing a door in a sliding manner by installing a window on a window frame in a straight line, and in the handle assembly installed on such a sliding window, a locker installed on the window side when closing the window is installed on the window frame side. An automatic locking device is provided that automatically locks and automatically locks the window, and when the window handle is rotated by a predetermined angle to open the window, the locker is unlocked from the striker of the window frame to open the window.

However, in the case of the sliding door handle assembly as described above, since the window is locked, that is, the locker on the window side is held by the striker on the window frame side and the locked state cannot be visually confirmed, there is anxiety about whether or not it is securely locked. For this reason, in order to check the locked state, the user has to close the window and then directly push the window toward the opening direction to check whether it is opened.

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, and the rotational motion of the handle shaft coupled to the driving gear of the automatic locking device is converted into a linear reciprocating motion of the slide member to open or The locking is configured to be selectively displayed, and the driving gear of the automatic locking device and the hook that is locked or unlocked by the striker of the window frame are configured to be interlocked by a rod and a stopper installed therebetween.

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.

The configuration of the prior art as described above is, 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 and at the same time, the handle The rotation of the shaft can be displayed by switching from'locked' to'open' by interlocking the sliding member.

However, on the contrary, when the hook is automatically locked to the striker by closing the window, the hook is automatically locked to the striker only by the operation of the stopper, so that the rotation of the handle shaft and the drive gear and the interlocking of the rod are not related to 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 firmly 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.
