The present invention is a device for easily locking a window.

Currently used window device is installed by inserting the structure in a certain position by the window frame manufacturer or have a professional installation personnel to install the window locks using the terrain, drill and various tools for installation.

In addition, most of the window lock device is a manual device, and the device that closes the window by rotating the handle to rotate the handle to lock the window by rotating the handle is used. This can reduce the durability of the handle because it is necessary to induce physical rotation when the window is deformed due to the external heat of the window and the window frame during summer, or when the window is deformed due to the deterioration of the window frame. There is a problem to let.

In addition, the rotary window locks have the inconvenience of opening and pulling the window again to check the locked state.

The present invention intends to lock and open the window easily by anyone, while more conveniently and safely installing the window locks installed in the sliding doors or windows currently used as described above.

If you want to lock the window while installing the window lock on the outside of the window, which is not the structure that cuts a part of the window, which is a conventional method of installing the window lock, and inserts it into the inside, push the window and push the gear operation protrusion. Rotating the window locks the window automatically only by pushing it. This allows everyone to easily lock the window by simply pushing it onto the window frame, and the return spring of the gear-driven protrusion pushes the window out of the window frame if the window is not locked securely so that the window can be securely locked at once.

In addition, the existing window locking device uses an operation method that requires to rotate the handle and pull the window back, but the present invention raises the operating lever so that the window is opened as the window is pushed out of the window frame.

This aims to compensate for the problem of the existing window locking device and to easily lock and open the window for everyone.

In order to achieve the above object, the present invention has a double locking device structure and describes the configuration and operation principle with respect to one side. If the up and down movement method is the same, the operation method of the lower surface is also the same.

The catch 300 is installed in the window frame 10 of FIG. 1 and the operating main body 400 is installed on the window to be used. 400A of FIG. 1 illustrates a state in which a window is opened by the return spring 402 of the gear operation protrusion by the gear operation protrusion 401 releasing the operating lever 408.

The catch 300 of Figure 3 is a fixed bolt hole for fixing to the window frame (300a) and the receiving plate 300b for pushing back the gear operation protrusion 401 and the operating plate 403 is inserted into the fixed operation plate is inserted It is comprised by the hole 300c.

The operation body 400 is installed on the handle 405 and consists of a gear operation protrusion 401 and a return spring 402 for pushing the gear operation protrusion inside. This gear actuating protrusion is positioned on the horizontal line of the catch 300b and the gear actuating protrusion 401 is pushed back when the window is pushed. At this time, the operation plate gear operation gear 410 embedded in the gear operation protrusion 401 rotates the operation gear 411 of the operation plate (403a of FIG. 3) to move the operation plate into the operation plate insertion hole of the catch unit 300 ( Pass 300c) to reach position 403 in FIG.

At this time, the working plate 403 is rotated out of the fixed plate 404 is designed to be pushed into the back of the operating plate by the fixed plate spring (404a). This is to induce a window or sliding door to be automatically locked while preventing the operating plate from rotating backward by the return spring 402 built into the gear operation protrusion 401.

The left side and the right side of FIG. 3 show an operating state. When the operation of the present invention is operated by the handle 405, the operating lever 408 installed inside the lower end of the handle 405 is provided with a fixed plate 404b is installed to always push the fixed plate in the direction of the operating plate The fixed plate spring 404a is positioned between the lower surface of the handle 405 and the operating lever 408.

When the window is locked, the gear operation protrusion 401 is automatically locked by rotating the operation plate when the window is closed by grasping the handle or holding a part of the window. However, when the window is unlocked, the operation lever 408 installed inside the handle is raised upward. Lifting the fixed plate 404 of the operating body part which is locked by blocking the rear portion of the operating plate 403 by the fixed plate spring 404a, the operation plate gear return spring 402 embedded in the gear operation protrusion 401 is catched by 300. The operation plate 403 inserted into the catch portion 300 rotates the operation plate gear operation gear 411 while pushing the receiving plate 300b of the support plate 300, whereby the operation plate 403 is inside the operation body 400. As he entered, the door was opened.

3 is an internal side view 400C showing the locked state of the window of FIG. In addition, 400B is an internal side view of the present invention showing the open state of the window.

To lock the window, push the window 20 or the handle 405 in the direction of the window frame 10, and pull the operating lever 408 installed inside the handle 405 for unlocking the window gear operation projection 401 As the gear operation protrusion 401 is pushed out by the return spring 402 installed inside, the operation plate 403 returns to function (403a in FIG. 3). In addition, when the operation lever 408 is placed again, the operation plate 403 is fixed to maintain the open state.

Both tactics work together in the upper and lower sides, so the hook-type double locking can prevent the forced window freezing time from the outside for a long time.

According to the present invention as described above, if you want to lock the window by pushing the window frame close to the window frame, the operation plate is inserted into the catch by the gear operation protrusion and the locking plate to automatically lock the window by preventing the return of the operation plate Pulling the operating lever installed inside the handle to open the fixed operating plate has the effect of pushing the window by the spring of the gear operation protrusion to easily lock and open the window.

It is easy to determine whether the window is locked or open with the naked eye because the window and the frame are always open when the window is not locked, and the two operation panels securely lock the window to cope with intrusion from the outside for a long time. It can be effective.
