Description

Automatic locking device for Sliding Window with Locking Confirmation Function}

The present invention relates to an automatic locking device for a sliding window that allows a window to be automatically locked and locked to a window frame by an operation of closing the window, and to unlock the window by operating a window handle to open the window, In particular, the present invention relates to an automatic locking device for sliding doors and windows with a locking confirmation function capable of visually confirming 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 such a sliding window, a locker installed on the window side is locked to a striker installed on the window frame side when the window is closed and automatically locked. , 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 automatic locking device for sliding windows as described above, there is anxiety about whether the window is locked securely because 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. Therefore, in order to check the locked state, the user has to check whether the window is opened by pushing the window directly toward the opening direction after closing the window.

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.

The present invention is to solve the above problems in consideration of the conventional problems, and its object is to display a locked or open display in conjunction with a slider interlocking with the locker when the locker of the automatic locking assembly is automatically locked or unlocked by the striker of the window frame. As a result, the lock can be marked only when the locker is firmly locked to the striker. Also, when the locker is unlocked from the striker and the window is open, the display cannot be changed from open to locked even if the window handle is repeatedly rotated. It is intended to provide an automatic locking device for sliding windows that is equipped with a locking confirmation function that can ensure reliability in terms of safety and quality as a security window by accurately displaying the locked and opened status.

The rotational center extension line (YY) of the linkage member 23 and the movement direction extension line (AA) of the linkage member 23 are set at a right angle to reliably link the linear motion of the linkage member 23 to the rotational motion of the display member 24 One side of the display member 24 on which the locking display portion 26a and the open display portion 26b are formed is formed in an arc shape with the one axis 24a as the center, so that the locking display portion 26a or open It allows the display portion 26b to be selectively positioned at the same position of the display hole 21.

At this time, in the present embodiment, the lock display portion 26a and the open display portion 26b are expressed in different colors, but the present embodiment is not limited thereto, and may be expressed in text or pictures.

It will be described the operation of the automatic locking device for sliding doors provided with a locking function made of this configuration.

First, as shown in FIG. 2, when the locker 33 is locked to the striker S and the window is locked, the slider 34 is in the locked position moved toward the rotating body 32 by the elastic force of the elastic member 35. , The interlocking member 23 of the locking means is moved toward the slider 34 by the elastic force of the elastic member 25 as shown in FIGS. 6 and 8 (a), and the end thereof is the inclined surface 34a of the slider 34 The locking display portion 26a of the display member 24 is visually exposed to the outside through the display hole 21 to confirm to the user that it is currently locked.

In such a locked state, when the user rotates the window handle 10 to open the window and rotates the rotating body 32 as in Fig. 3 (a), the slider 34 moves to the open position. The locker 33 rotates to a position where the locker 33 is unlocked from the striker S by the torsion spring 33a to open the window.

In addition, the link member 37 of the auxiliary opening means interlocks with the slider 34 to press the rotating arm 36 so that the free end of the rotating arm 36 rotates about one axis and pushes the window frame to separate the window a predetermined distance. Therefore, the user can help the operation of opening the window by rotating the window handle 10.

In addition, the interlocking member 23 of the lock confirmation means, as in Fig. 7 (a), as the slider 34 moves from the locked position to the open position, the end of the holding surface 34b of the slider 34 ), so that the interlocking member 23 moves in a direction away from the slider 34.

Therefore, as shown in (a) and (b) of Fig. 8, the end of the interlocking member 23 pushes the display member 24 and rotates around the one axis 24a, so that it is exposed through the display hole 21. The locked display unit 26a is converted to the open display unit 26b and displayed, and the user can visually check this to know that the window is open.

When the user releases the window handle 10 while the window is open in this way, the window handle 10 is in its original position, so the rotating body 32 is also rotated to its original position as shown in Fig. 3(b), and the slider 34 Receives a force to move toward the rotating body 32 by the elastic restoring force of the elastic member 35, but does not completely return to its original position by stopping one side of the slider 34 caught on one side of the locker 33 in the unlocking position.

Therefore, as shown in Figure 7 (b), the interlocking member 23 of the locking means can be continuously positioned on the holding surface 34b of the slider 34, and thus the display hole 21 of the handle body 20 It is possible to continuously maintain the open display portion 26b expressed through. In this state, even if the window handle 10 is operated in the forward or reverse direction, since the slider 34 does not move completely to the locked position, there is no change from the open display to the locked display.

Subsequently, when the user closes the window, the locker 33 is pushed to the striker S and locked while rotating as the window approaches the window frame as shown in FIGS. 2 and 3, and the rotating arm 36 of the auxiliary opening means Also in contact with the window frame, it is inserted back into the housing 31.

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 elastic member 35, and in this process, the locking projection 33b of the locker 33 is Since the slider 34 is caught and held, the locker 33 can be kept locked to the striker (S), and the locker (33) is locked to the striker (S) only when the slider 34 is accurately moved to the locked position. You can keep the state sure.

When the slider 34 moves to the locked position in this way, the interlocking member 23 of the locking means as shown in FIGS. 6 and 8A is the inclined surface 34a from the holding surface 34b of the slider 34 The contact position is changed to move in a direction close to the slider 34 by the elastic force of the elastic member 25, and at the same time, the display member 24 rotates around one axis 24a, so that the display hole 21 The display is switched from the open display portion 26b to the lock display portion 26a.

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 reliably 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.
