Description

Automatic locking device for window

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a window automatic locking device, more particularly, to a window automatic locking device capable of fully locking a window so that the window is not opened over a certain distance, .

Generally, there is no problem from the theft of indoor windows. However, windows exposed to the outside in apartment houses or single houses are vulnerable to theft such as theft.

Therefore, there is a problem in that the lock of the window is always locked in order to prevent theft when the user goes out, and when there is no other safety device, there is a safety problem such as falling into a window where an infant or a child is open. An expensive security window is installed to solve the problem, but in this case, it is difficult to escape in case of an emergency such as a fire as well as a cost.

Thus, in the past, a device has been proposed to prevent theft of the window due to the opening of the window by a certain distance.

Conventionally, a window opening / closing control device for limiting the opening / closing degree of such a window is disclosed in Japanese Utility Model Registration No. 20-0387008 (Jun. 16, 2005), which fixes a body to a window frame, The stop bar is provided with a latch pin operated in the lateral direction according to the operation of the handle, and the window frame is formed with a hole through which the latch pin is inserted.

Therefore, when the ratchet pin projected by manipulating the handle is inserted into the hole formed in the window frame, the window is opened only by a certain distance, and when the ratchet pin inserted in the hole is retracted to release the inserted state, the window is completely opened .

However, such a conventional apparatus has a problem that it is very difficult to install because the body is fixed to the window frame and the window frame is formed with a hole for inserting the bolt pin, and there is a problem that the hole and the bolt pin need to be re- There is a risk that the operation of the lock pin is inconvenient and the lock operation is difficult to be carried out, thereby causing a risk of theft.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a method and apparatus for reducing the manufacturing cost by simplifying the structure, To provide an automatic window locking mechanism.

The automatic window locking device according to the present invention comprises a base plate attached to an inner surface of a window, a stopper coupled to a bracket formed on the base plate, and a support plate installed on a back surface side of the stopper, Is provided.

The present invention has a simple structure so that it is easy to manufacture, the manufacturing cost is remarkably reduced, the installation is easy, and the operation is surely performed, thereby preventing stolen children and children from falling down and ventilating the room smoothly.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an installation state of an automatic window locking device according to the present invention, FIG. 2 is a perspective view showing another installed state of the automatic window locking device according to the present invention, Fig.

The present invention is applied to a sliding window system that intersects with each other. In the drawings, an automatic locking member 30 is installed inside windows 10 and 20 provided side by side.

Glass windows 12 and 22 are respectively coupled to the inside of the window frames 11 and 21 of the windows 10 and 20 and an automatic locking member 30 Is attached.

The automatic locking member 30 includes a base plate 31, a stopper 33 rotatably coupled to a bracket 32 spaced from the top of the base plate 31, And an elastic member 34 which is installed on both sides and applies an elastic force to one side.

A stopper supporting bracket 50 for supporting a lower portion of the stopper 33 is formed at one side of the bracket 32. The stopper supporting bracket 50 is provided at a lower side of the window 20, The load is supported so that the stopper 33 is not deformed.

A support plate 35 is provided at the rear side of the bracket 32 to prevent the stopper 33 from rotating toward the back side and the support plate 35 is formed to be inclined toward the bracket 32 .

It is preferable that the support plate 35 be provided with further improved rigidity by folding the base plate 31.

A fixing portion 36 is formed in front of the base plate 31. The fixing portion 36 is fixed to the leading end of the pulling string 37 and the other end is pulled out through the stopper 33. [

A plurality of fastening portions 38 and 39 are formed on both side edges of the base plate 31 so as to be fastened and fixed to the window frame 11 of the window 10 with screws or the like.

The pulling string 37 is pulled out from the fixing portion 36 through the stopper 33 into the hole of the coupling portion 39 so that the user pulls the pulling string 37 to change the posture of the stopper 33 So that the windows 10 and 20 can be opened.

One or more of the fixing portions 36 may be formed at one end of the base plate 31. The pulling string 37 may be formed by a fastening portion 39 that is not used after being pulled out of the stopper 33 .

The fastening portions 38 and 39 are formed on both sides of the fastening portions 38 and 39 so that they can be suitably used depending on the attachment position of the window 10. [

The base plate 31 and the stopper 33 are most preferably formed of a metal material. The base plate 31 and the stopper 33 may be formed of a synthetic resin material.

In this embodiment, the base plate 31 is shown as a butterfly shape. However, the base plate 31 may be formed in various shapes such as leaves, insects, animals, fruit, and the like.

The automatic locking member 30 can be attached to any position of the window 10, and one or more of them can be fixedly used. In the case where two pieces are provided on the upper and lower sides, as shown in FIG. 2, a separate pulling-cord guide member 40 for guiding the pulling-up string 37 to the center can be provided.

1, the automatic opening / closing control device according to the present invention is installed on one side of the sliding window, and one automatic locking member 30 is installed on the upper side of the window 10 as shown in FIG. 1, Two can be installed at the top and bottom.

It is preferable that the installation position of the automatic locking member 30 is determined according to the size of the windows 10 and 20, and it is most preferable that the automatic locking member 30 is opened within a distance of 15 cm which is difficult for a person to enter and exit.

As shown in FIG. 2, the automatic locking member 30 is preferably attached to the upper and lower portions of the one side window 10 at a predetermined distance from one side of the vertical window frame 11, The distance from the window frame 11 is preferably determined according to the degree of opening of the windows 10 and 20.

The automatic locking member 30 is attached to the bottom surface of the base plate 31 by selectively attaching it to the bottom surface of the base plate 31 from a double-sided adhesive tape, silicone, or adhesive, The fastening portions 38 and 39 formed on both sides of the window frame 11 are positioned on the upper and lower sides of the window frame 11 and then fastened with a screw so that the automatic locking member 30 Can be more firmly fixed.

4, the stopper 33 is erected by the elastic force of the elastic member 34. At this time, when the window 20 is opened, The side surface of the vertical window frame 21 is blocked by the stopper 33 and is no longer opened, thereby preventing theft or the like caused by the full opening of the window.

At this time, when the window 20 is fully opened as required, the stopper 33 may be pulled by pulling the pulling string 37 and pulling the stopper 33 in 90 ° So that the window 20 can be fully opened beyond the automatic locking member 30 as shown by the one-dot chain line.

In this embodiment, the stopper 33 is rotated by pulling the pulling string 37. However, the present invention is not limited thereto, and the stopper 33 may be directly held by the hand without rotating the pulling string 37 The window 20 can be opened.

When the window 20 is fully opened, the stopper 33 is automatically raised by the elastic force of the elastic member 34 to keep the window 20 locked, By opening only as far as the distance, theft is prevented.
