Description

Auto locking apparatus for sliding windows

The present invention relates to an automatic locking device for windows and doors, and more particularly, the locking device is automatically locked by interlocking the windows, and the locking device is interlocked automatically by operating the handle to open the windows. The present invention relates to an automatic locking device for windows and doors, which enables the locking and releasing operation of the locking device to be quickly and conveniently performed when opening and closing windows and windows by being in an unlocked state.

Generally, windows are general terms of windows or doors installed through the inside and outside of the building. The windows are divided into wood and metal materials according to the materials used, and there are various types of doors. There are sliding doors, fine doors, material doors, revolving doors and doorways. In the case of windows, there are built-in windows, single door windows, double door windows, fine windows, ornari windows, revolving windows and middle windows.

As mentioned above, the sliding doors of the sliding doors that are pushed to the side to open and close the doors are mainly used for the partition between the room and the room, the double door in front of the Daecheong, or the doors and windows of the apartment or building.

As a prior art of the locking device used for such a sliding window, for example, the Republic of Korea Utility Model Registration No. 20-0409479 (designation name: automatic locking device for button-type window) is known.

The conventional automatic locking device for windows and doors comprises a lock having a strike fixed to the window frame and a hook fixed to the window and held by the strike. When the window is closed, the hook of the window side locking part is the window frame side. When the window is closed, the door is locked and locked at the same time. When the window is opened, press the button installed on the window, and the lever that interlocks with the button press operates the hook to release the window from the strike on the window frame side. It is supposed to open.

However, in the conventional automatic lock device for windows and doors having such a configuration, when attempting to open a window while the hook of the window lock is held by the window frame side strike, the hook is pressed first by pressing a button separately installed on the window side every time. The problem of opening the window is very cumbersome because it is necessary to open the window by holding the handle and then release the jam, and the user locks the handle by holding the handle with one hand and operating the button with the other hand. There is a disadvantage in that it is inconvenient to use both hands when releasing, and when only one hand is used, the locking device must be operated first and then the handle must be opened to open the door so that the door cannot be opened quickly.

In addition, the above-described conventional configuration is that a separate button for releasing the lock state and parts for maintaining the same are installed in the window, which increases the manufacturing cost by increasing the manufacturing cost due to the complicated configuration and the number of parts. Of course, the installation work on the window is also complicated, and since the hook of the window locking part is held by one side of the window frame side strike, when the external force acts in the direction opposite to the direction in which the hook is held, the locking state is easy. Since it can be released, it is weak in terms of the robustness and safety of the locking structure, and an improvement thereof is required.

The present invention is to solve the conventional problems as described above, its purpose is to automatically lock the window side locker to the window frame side locking brackets when the window is closed, the automatic locking state is maintained, the window of the handle The operation of locking the window locker by the operation and releasing it from the lock bracket on the window frame is made very smoothly by a simple configuration, and at the same time, it is possible to simultaneously release the lock and open the window with one hand. An object of the present invention is to provide an automatic locking device for windows and doors, which opens and closes windows very quickly and conveniently.

In addition, the present invention does not have a separate button for releasing the locked state of the window, thereby releasing the locked state in conjunction with the operation of the handle, thereby simplifying the configuration by removing the separate button and parts for maintaining the same. In addition, the number of parts can be reduced, thereby lowering the manufacturing cost, thereby reducing the cost of installation.The lock state of the lock is secured by forming a pair of lockers of the locking device so as to be simultaneously held on both sides of the lock bracket on the side of the window frame. It is to provide an automatic locking device for windows and doors that do not release the lock even if the external force is applied in the opposite direction to the locker is held.

A torsion spring having a main surface and a fixed step formed on the circumferential surface, and elastically installed between the locker and the case, and a torsion spring for applying an elastic restoring force so that the locker always operates in an unlocked position, and rotatably about an axis in the case. Installed and inserted into the fixed step of the locker from the locked position of the locker A holding member having a fixing part operating between the unlocking positions, a movable member installed in the case so as to be linearly movable to move the fixing part of the fixing member between the fixing position and the unlocking position; A spring member which is elastically installed between the movable members and exerts an elastic restoring force so that the fixing portion of the fixing member is always operated to a fixed position, and a coupling hole rotatably installed in the case and engaging the handle shaft of the window handle to the center of rotation. It is characterized by an automatic locking device for windows and doors, which comprises a circular portion and a rotating body provided with a pressing protrusion for protruding from the circular portion to operate the pressing member.

In addition, the present invention is characterized in that the automatic locking device for windows and doors configured to install the locker and the fixing member symmetrically on both sides of the movable member, respectively, so that the locking portions of both lockers are locked and released from both sides of the window frame side locking brackets, respectively.

In addition, the present invention is characterized in that the automatic locking device for windows and doors formed with an insertion cutout portion in which a portion of the circular portion is inserted into one side wall surface of the case facing the circular portion of the rotating body.

The automatic locking device for windows and doors of the present invention having such a characteristic configuration, while the pressing portion of the window locker is pushed by the window frame side locking bracket when the window is closed, the locking part of the locker is rotated to the locking position to keep the locking bracket locked. As the fixing part of the member is inserted into the fixing step of the locker to keep the lock state, the operation of closing the window and the automatic locking of the window is made very smoothly. By interlocking the fixing member and detaching the fixing part from the fixing step of the locker, the locking part of the locker is released from the locking bracket of the window frame, so the operation of releasing the locking state with the opening of the window is very smooth. The effect of opening and closing the windows is very quick and convenient. .

In addition, the present invention, when opening the window, as the locking state of the locking device is released by the operation of the handle, there is no need for a conventional button and parts for maintaining the separate installation for the release of the locking device, thereby configuring the locking device This simplified and reduced number of parts reduces the manufacturing cost by reducing the manufacturing cost as much as possible, and the case set according to the limited installation space of the window as a part of the rotating body combined with the handle is inserted into one side wall of the case. The position of the handle can be spaced away from the window frame as much as possible without widening the width of the handle.This allows sufficient space between the handle and the window frame while the window is closed, so that it does not interfere with the window frame frame during grip and operation of the handle. Can be used.

In addition, the present invention is configured so that a pair of lockers are simultaneously held on both sides of the window frame side locking bracket, so that the locking state of the window is firm and the external force acts in the direction in which the lockers are held from the outside or vice versa. The lock is not released by the locker, so external intrusion can be reliably prevented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a front view of a window installed with an automatic lock for a window of the present invention, Figures 2 and 3 are a perspective view and an exploded perspective view showing an automatic lock for a window, Figures 4a to 4c is the operation of the automatic lock for the window It is a cross-sectional block diagram which shows the state.

As shown, the automatic locking device for the window of the present invention, the locking bracket 11 is fixed to the window frame frame (A) of the window, the case 12 installed on the window frame (B), and the case 12 It is installed in the lock bracket 11 is provided with a locker 20 is held or released on the locking bracket 11, the locking bracket 11 is formed in a substantially c-shaped cross-section or grooves on both sides to be described later The locking portion 21 of the locker 20 is capable of holding and releasing the locking.

The locker 20 is rotatably installed around the shaft 13 in the case 12, and on one side, a locking portion 21 and a locking bracket (eg, held by the locking bracket 11 when the window is closed). 11 is provided with a pressing portion 22 is pressed by the pressure is exposed to the outside of the case 12, the locking portion 21 is held in the locking bracket 11 and the unlocking position to release the locking The other side of the locker 20 located inside the case 12 has a circumferential surface 23 centering on the axis 13 which is the rotation center of the locker 20 and the circumferential surface 23. The formed fixed step 24 is provided.

In addition, a torsion spring 25 is elastically installed between the case 12 and the locker 20, and the torsion spring 25 always moves the locking portion 21 of the locker 20 from the window frame side locking bracket 11. An elastic restoring force is applied to the unlocking position for releasing the lock. Therefore, the locking portion 21 of the locker 20 is compressed when the lock position rotates, and the locking portion 21 of the locker 20 is returned to the unlocked position by the elastic restoring force generated during the compression. 20, the locking portion 21 is to be maintained in the locked state by the fixing member 30 in the locking position held by the locking bracket (11).

The fixing member 30 is rotatably installed about the shaft 14 in the case 12, and a fixing part 31 is formed at one side thereof so that the locker 20 is in the locked position. The locking step of the locker 20 is maintained by being inserted into the fixed step 24 of the locker 20, and the fixed step 24 of the locker 20 by the movable member 40 elastically installed by the spring member 41. It is intended to operate between the locked position to be inserted and the unlocked position to be released.

The movable member 40 is installed in the case 12 so as to be linearly movable, and is connected to an interlocking part 32 formed on the opposite side of the fixing part 31 of the fixing member 30, and the spring member 41 is connected to the case. It is elastically installed between the 12 and the movable member 40 so that the elastic restoring force for always operating the fixed portion 31 of the fixed member 30 to a fixed position is applied, the movable member 40 is located in a position adjacent thereto. The rotating body 50 is provided to operate.

The movable member 40 has a circular portion 51 rotatably installed in the case 12 and having a coupling hole 51a to which the handle shaft 15a of the window handle 15 is coupled to the center of rotation. The pressing protrusion 52 protrudes from the circular portion 51. Therefore, by the rotation of the rotating body 50, the pressing protrusion 52 pushes the movable member 40 to move immediately before. At this time, the elastic restoring force of the compressed spring member 41 causes the movable member 40 to return to the rotating body 50. It is possible to return to the () side.

In addition, the present invention, the locker 20 and the fixing member 30 configured as described above are installed symmetrically on both sides of the movable member 40, respectively, so that the locking portions 21 of both rockers 20 are locked to the window frame side. Engaged and released from both sides of the bracket 11, respectively, an insertion cutout portion 12a is formed on one side wall surface of the case 12 opposite to the circular portion 51 of the rotating body 50 so that the rotating body ( Rotation of the rotating body 50 with respect to the width L1 of the case 12 set in accordance with the width size of the window frame B by inserting a portion of the circular portion 51 of 50) as shown in FIG. 4A. The center position length L2 is lengthened so that the distance between the window handle 15 and the window frame frame A coupled to the coupling hole 51a of the rotating body 50 can be spaced apart as much as possible.

Referring to Figure 4a to 4c the operation of the present invention made of such a configuration as follows. First, when the window is open, as shown in FIG. 4A, the locking portion 21 of the locker 20 is in the unlocked position, and the fixing portion 31 of the fixing member 30 is the circumferential surface (of the locker 20). 23 is in a locked release position and the spring member 41 of the movable member 40 is in a compressed state.

In this state, when moving toward the window frame to close the window, the window frame side locking bracket 11 is pressed by the pressing portion 22 of the locker 20, so that the locker 20 is rotated about the axis 13, As in 4b, the locking portion 21 is moved to the locking position held by the locking bracket 11 so that the window is automatically locked. At this time, the torsion spring 25 elastically installed in the case 12 and the locker 20 is compressed to generate elastic restoring force, but as the locker 20 rotates, the torsion spring 25 is in close contact with the circumferential surface 23 of the locker 20. Reverse rotation of the locker 20 by moving to a fixed position inserted into the fixing step 24 of the locker 20 by the elastic restoring force of the spring member 41 in which the fixing part 31 of the fixing member 30 is compressed. Since the locking portion 21 of the locker 20 is prevented, the locking state of the locking bracket 11 can be maintained. In this way, the operation of closing the window and the operation of locking the window at the same time are made very smoothly by a simple configuration, and the locking operation is very quick and convenient.

Subsequently, in the case of opening the window while the long door is locked as described above, when the handle 15 installed on the window frame B is rotated, the rotating body 50 coupled with the handle shaft 15a rotates together. As shown in FIG. 4C, the pressing protrusion 52 pressurizes the movable member 40. As a result, the spring member 41 is compressed and the movable member 40 is pushed to move linearly. The government 31 is separated from the fixed step 24 of the rocker 20. Therefore, the locker 20 is reversed by the elastic restoring force of the compressed torsion spring 25, and the locking portion 21 of the locker 20 is released from the locking bracket 11 to move to the unlocked position. Therefore, the window can be opened, and the fixing part 31 of the fixing member 30 is brought into close contact with the circumferential surface 23 again by the reverse rotation of the locker 20, and the spring member 41 again. Since it is in a compressed state, it is possible to repeat the above-described operation when the window is closed again as shown in FIG. 4A.

In this way, even when the window is locked, the locker 20 is interlocked by interlocking the rotating body 50, the movable member 40 and the fixing member 30 only by holding and rotating the handle 15 for opening the window. Since the lock is released, the unlock operation is very smooth, and the window can be opened quickly and conveniently with one hand.

In addition, in the present invention, the locker 20 and the fixing member 30 are installed symmetrically on both sides of the movable member 40, respectively, and as shown in FIG. Since both sides of the window frame-side locking brackets 11 are held, the locking state of the window is generally balanced to be firm and firm, and an external force is applied to release the locking portion 21 of the locker 20. In this case, even if an external force is applied in any direction, the locking portions 21 of both lockers 20 do not leave the locking bracket 11 to prevent external intrusion.

In addition, the present invention can reduce the width length L1 of the case 12 by inserting and inserting a portion of the circular portion 51 of the rotating body 50 into the insertion cutout portion 12a formed in the case 12. have. Therefore, since the rotation center position length L2 of the rotating body 50 can be set relatively long with respect to the width length L1 of the case 12 which is determined according to the width of the window frame B, the rotating body ( The position of the handle 15 to which the handle shaft 15a is coupled to the coupling hole 51a of the 50 can be spaced apart from the window frame frame A as much as possible, so that the handle 15 and the window frame in the closed state of the window are closed. Since the space between the frame (A) is secured wide, there is no interference with the window frame frame (A) when the user grips or manipulates the handle (15) to open the window can be used more conveniently.
