Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a door lock,

The present invention relates to a window locking device having a security function enhanced by magnetic force, and more particularly, to a door locking device using a permanent magnet and an electromagnet to smoothly and quickly perform a crime prevention and locking operation, And to improve soundproofing, insulation, airtightness, watertightness and windproofing performance by minimizing the number of the door locks.

Generally, the window system includes a window frame formed in a rectangular frame grid shape and mounted on a wall, and a window that is opened and closed so that the user can slide in the window frame.

Particularly, in the window frame, a guide (rail) is formed so that the window can be slid in a predetermined direction, and the guide is formed so that a pair of windows are aligned with the number of the window so that the window can receive the sliding guide.

Meanwhile, a roller (racetrack) may be further provided under the window inserted into the guide. The rollers guide the guide along the guide so that it can move smoothly and quietly.

However, such a conventional window system has the following problems.

(1) A separate locking device shall be provided for theft prevention and locking. Such a locking device is required to close the window and then perform the locking operation again. Therefore, the elderly person or the child may be exposed to the crime because the locking operation is difficult or easily forgotten.

(2) Locking device It is also troublesome for children or elderly people to accurately rotate the latches to cause the locking action because the latches must be rotated and fixed.

(3) Such a conventional locking device is composed of a latch mounted on a window so that locking is performed when the window is closed, and a striker mounted on the window frame such that the latch is substantially engaged with the latch. At this time, part of the striker protruded in the width direction of the window frame (direction facing to the window), which was a factor for damaging the aesthetics.

(4) Due to the protruding striker, there is a gap between the window frame and the window frame. Since there is a fear that rainwater, dust, and noise may enter from the outside through the gap, the gap serves to lower the resistance to wind pressure, water tightness, air tightness, and soundproofing.

(5) In order to solve the problem of the above (4), the locking device is required to further include auxiliary materials such as mohair or gasket, so that the structure is complicated as a whole, and the manufacturing cost is increased accordingly.

(6) However, these auxiliary materials are effective in blocking the gap, but in addition to enhancing the adhesion between the window frame and the window frame (frictional force), the weight of the window is increased, thereby preventing the elderly or child easily opening and closing the window. In particular, this could lead to injury to people in case of an emergency such as a fire.

(7) In addition, since the striker is fastened and fixed to the window frame by a screw, the conventional locking device causes abrasion and breakage due to impact applied due to frequent opening of the window. Therefore, there is a need to replace such a striker or replace and repair the entire locking device.

(8) Due to the striker protruding from the window frame, a slight gap is generated between the window frame and the window frame. When the nail is inserted into this gap and the nail is pulled, the locking device is released, which is vulnerable to security.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and provides a simple operation in which a locking operation is performed by opening and closing a window using an electromagnet and a permanent magnet and a repulsive force is generated by applying power to the electromagnet in order to open a window, So that it is not only easy to operate but also can improve the locking and the anti-theft effect.

In addition, the present invention minimizes the gap between the window frame and the window frame due to the excellent engagement between the window frame and the window frame when a magnetic force is not generated in the electromagnet as in a closed state of the window, It is another object of the present invention to provide a locking device for a window with enhanced security function by using a magnetic material capable of improving soundproofing, insulation, airtightness, watertightness and windproofing performance.

According to an aspect of the present invention, there is provided a locking device for a window with a security function enhanced by using a magnet according to the present invention, comprising: an electromagnet mounted on one side of a window frame facing a window frame; A permanent magnet mounted on a side bar of the window frame so as to face the electromagnet; A first sensor and a second sensor respectively installed in the window frame and the window for detecting the open and closed states of the window; A controller mounted on a window frame or window to control power supply to the electromagnet based on signals of the first sensor and the second sensor to control locking and unlocking of the window; And a battery for supplying power to the electromagnet under the control of the controller, wherein the controller is configured to: (1) magnetically magnetize the electromagnet for a predetermined time when the user inputs a unlocking signal, (2) when a detection signal of the first sensor which senses that the second sensor is adjacent is input, it is determined that the window is closed, and the power is applied to the electromagnet, So that the window is smoothly closed by the reduction of the repulsive force.

In particular, the permanent magnet and the electromagnet are installed inside the side bar and the window, respectively, which are configured to be in contact with each other in the form of a flat plate.

Further, the electromagnet is a superconducting magnet coil.

According to the locking device for a window in which the crime prevention function is enhanced by using the magnet of the present invention, the following effects can be obtained.

(1) When the window is closed, the window is locked by the permanent magnet, so that the lock operation is easy and quick.

(2) Since the locking operation is performed only by closing the window without taking a separate locking operation, anyone can easily and quickly provide the locking function, thereby enhancing the theft prevention effect.

(3) Since the window is opened and closed without being in contact with the window frame, it is possible to prevent the occurrence of noise due to the opening and closing of the window.

(4) Unlike the conventional locking device, when the window is closed, the window is in close contact with the window frame, so that the gap therebetween can be eliminated. As a result, it is possible to almost completely block the inflow of foreign matter, rainwater, dust, and noise through the gap, and as a result, it becomes possible to improve soundproofing, insulation, airtightness, watertightness and windproof performance.

(5) Therefore, children and elderly people can easily unlock the window through the controller, as well as open and close the window easily due to the weight reduction.

(6) When permanent magnets and electromagnets are mounted on windows and window frames as interior decoration, it is practically non-contact type, so it is possible to prevent breakage of such locking devices and use them semi-permanently.

(7) In particular, since it is possible to eliminate a gap between a window and a window frame, it is difficult to insert a specific tool therebetween to forcibly release the locking device, thereby enhancing the security function.

(8) When the window is closed, the window is guided to be closed smoothly by using the repulsive force of the magnetic force, so that the damage caused by the impact caused by the window hitting the window frame can be prevented in advance.

That is, the window frame 100 is provided with a fixed window and a sliding window, or a pair of sliding windows. Thus, the permanent magnets 131 are mounted on the side bars 130 that abut when the windows 200 to be slid are closed. In particular, the permanent magnet 131 uses a magnet that forms a magnetic pole in one direction.

The permanent magnet 131 may be attached to the window frame 100. However, since the permanent magnet 131 may be detached due to frequent use, it is preferable that the permanent magnet 131 is firmly fixed with a screw or the like. Of course, more preferably, the window frame 100 is extruded or injection-molded so that the permanent magnet 131 can be mounted inside the window frame 100, so that the permanent magnet 131 is brought into direct contact with the window 200 So as to minimize the damage caused by the contact.

When the permanent magnet 131 is exposed to the outside, the permanent magnet 131 is formed to have the same length as the entire length of the side bar 130, so that the window frame 100 and the window 200 In order to minimize the gap between them.

The first sensor 140 is mounted on the upper bar 120 of the window frame 100. The first sensor 140 may be mounted at any position as long as it can detect the position of the second sensor 220 to be described later. 1, the first sensor 140 is mounted on the end side of the side where the window 200 is closed.

The first sensor 140 outputs the detected signal to the controller 300. At this time, it is possible to output a signal in a wired manner, but a wireless transmission unit for a short distance is further configured, It is preferable that the communication is performed with the mobile station.

The second sensor 220 is mounted on the window 200. At this time, it is preferable that the second sensor 220 is installed at a position where the window 200 can be detected by the first sensor 140 in a locked state, that is, in a completely closed state. The closed state of the window 200 can be detected by detecting the position of the first sensor 140 and the second sensor 220 when the window 200 is in the closed position.

The second sensor 220 may have a sensing function similar to the first sensor 140 or may have only a function as a signal generating unit for detecting the position of the window 200 by the first sensor 140 You may.

The electromagnet 230 is mounted on the window 200 so as to face the permanent magnet 131. This electromagnet 230 is selectively magnetized from the battery under the control of the controller 300 to generate a repulsive force.

However, it is preferable that the electromagnet 230 is mounted inside the window 200 to avoid damage due to contact. Also, the mounting method is firmly fixed using a screw or the like.

The electromagnet 230 is preferably made of a superconducting magnet coil so that the self-resistance value is minimized so that the current continues to flow so that a strong current can be easily supplied.

It is preferable that the electromagnet 230 can minimize a gap between the electromagnet 230 and the window frame 100 when the window 200 is closed as in the case of the permanent magnet 131 described above.

The battery is a component for supplying power to the above-described electromagnet 230 under the control of the controller 300.

(2) Opening of window (unlocking)

If the user who intends to open the window inputs a signal for releasing the lock through the controller 300 (the on / off button or the release switch), the controller 300 applies power to the electromagnet 230 to rotate the permanent magnet 131 So that the window 200 is separated from the window frame 100. In this case, At this time, the power application time to the electromagnet 230 is set in advance in consideration of the time when the window 200 is separated from the window frame 100, the load of the window 200, and the like.

At this time, the power of the power applied to the electromagnet 230 is gradually and strongly controlled so that the repulsive force generated between the electromagnet 230 and the permanent magnet 131 is prevented from suddenly changing, while the window 200 is smoothly unlocked It is preferable to open it.

(3) Closing the window

The second sensor 220 moves as the window 200 is closed and the first sensor 140 detects the proximity of the second sensor 220 when the window 200 comes to a substantially closed position do. Then, the detection signal detected by the first sensor 140 is output to the controller 300.

The controller 300 magnetizes the electromagnet 230 to generate a repulsive force. At this time, the controller 230 gradually applies a power of a predetermined intensity and gradually weakens the repulsive force to gradually weaken the repulsive force with respect to the permanent magnet 131, so that the repulsive force with respect to the permanent magnet 131 gradually decreases A smooth closing operation is performed without the window 200 impacting on the window frame 100.

Through the above-described control, the present invention can easily perform locking operation by locking and unlocking using magnetism, as well as a gap generated by the stopper and the striker of the conventional locking device can be minimized in the present invention Insulation, airtightness, watertightness and windproof performance.
