The present invention relates to a locking device of a sliding window that is configured to prevent external intrusion in advance by hardening the locking state of the sliding window that is opened and closed by sliding to both sides so that it is impossible to release from the outside.

In general, sliding windows are installed in a predetermined frame to perform the opening and closing function by sliding in both directions along the guide rail, and does not need to secure a space for opening and closing the windows and most sliding windows are composed of a plurality of sliding windows. It is configured to provide convenience for the use of the windows.

Such sliding windows are usually made of wood or aluminum frame, and the locking operation part is installed on the inner window frame and the locking member is mounted on the outer window frame so that the clasp pieces constituting the locking operation part are caught or released by the locking member. It consists of a window lock.

That is, as shown in FIGS. 1A and 1B, the locking operation part 11 mounted on the inner window frame 10 has a hemispherical locking part 13 formed on one side of the handle 12 installed to be rotatable. The outer window frame 14 at the corresponding position is provided with a locking member 15 having a hook-shaped hook piece, and the locking portion 13 is locked to the locking member 15 by rotating the handle 12. As it is caught or disengaged, the inner and outer window frames can be locked.

However, since a conventional window lock can usually be identified from the outside through glass, when the user neglects to lock the window, the door may be more likely to be invaded, and the lock is opened by opening the inner window frame 10. When the open window is closed while the negative handle 12 is rotated to the locked position, the door 12 may be damaged while causing the breakage or failure of the locking device itself by hitting the locking member 15 of the outer window frame 14.

As a technology filed in consideration of these points, Korean Utility Model Registration No. 0182736 discloses that the clasp piece is elastically operated to perform a locking function by operating a button that is integrally installed on a handle of a window, or As in the Korean Utility Model Registration No. 0252593, it is possible to open the window by releasing the latch from the clamp by the button operation mounted on the body, and by the elastic action of the latch by the movement of the clamp when the window is closed. Disclosed is a technique configured to perform a locking function.

However, in the prior art having the above-described configuration, since an elastic means such as a spring must be installed, the assembling work becomes difficult and the structure becomes complicated, as well as the locking function at any point for the entire window length. This implies that the locking force is weak and easily broken by external force.

The present invention has been made to solve the above problems, an object of the present invention is a simple structure in configuring the locking device of the sliding window, so that the locking function can be performed at least three points for the entire length of the window frame more robust The present invention provides a locking device for sliding windows that can securely and reliably perform a locking function.

Locking device of the sliding window of the present invention for achieving the above object, in the configuration of the locking device on the window frame of the sliding window to be opened and closed on both sides, the base mounted on the front end side portion of the inner window frame and is fixed to the base And a locking lever installed on the outside of the cover and a locking unit configured to slide and move within the base in association with the operation of the rotating lever, and a bracket on the outer window frame to correspond to the locking unit. It is characterized in that the locking unit is configured to bind or release when operating the rotation lever.

Here, the locking unit is a slide configured to operate in the vertical direction connected to the front end of the first locking portion and the first locking portion slides in the horizontal and vertical directions in conjunction with the operation of the rotation lever on the base, respectively. And a second locking portion connected to the tip of the slide bar and configured to emerge from both ends of the base.

In addition, the first locking portion has an operation piece which is operated by the rotation lever, and is operated in a horizontal direction when the operation piece is rotated and configured to emerge from the base to the outside and the horizontal movement piece in conjunction with the horizontal movement piece. It consists of a vertical movable piece which is divided to slide in the vertical direction.

In addition, the arm end of the operation piece is characterized in that the protruding pin is formed to be maintained in the engaging hole of the horizontal moving piece, and the U-shaped hole formed in the horizontal moving piece is guided to the body side of the operation piece.

Fixing pins are mounted at both ends of the horizontal moving piece, and the fixing pin is assembled into the inclined hole formed in the vertical moving piece.

In addition, the second locking portion, a fixing pin is installed at one end of the locking member having a locking ring and is bound to the front end of the slide bar, and a guide pin is mounted on one side of the fixing pin and formed on the fixing piece of the base. It is connected to the type guide hole.

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

2 to 7a, 7b is a view for explaining the locking device of the sliding window according to the present invention, the present invention is mounted on the base 20 and the base 20 which is mounted on the tip side portion of the inner window frame 10 It is provided with a cover 21 which is covered and fixed, the rotation lever 22 is mounted in the substantially central portion of the outside of the cover 21 is configured to operate the locking unit installed in the base 20 in the forward and reverse directions have.

In addition, at a corresponding position of the outer window frame 14, a locking piece 23a is formed at the center portion and a bracket 23 having a binding groove 23b at both ends thereof to perform the locking and releasing function by the locking unit. Is equipped.

In the present embodiment is shown an example to operate the locking unit by installing the rotation lever 22 on the outside of the cover 21 to operate the locking unit, a conventional key button is installed in place of the rotation lever It can be configured to be operated by using a bundle of locks or by operating a key.

The base 20 is manufactured in the form of a flat plate to be attached to the side portion of the inner window frame 10 using a small screw (not shown) or the like, and fixing pieces having insertion grooves 24a at both ends of the body. (24) is provided, and the guide hole 24b cut | disconnected in substantially A shape in the surface of this fixing piece 24 is formed.

The base 20 is covered with the cover 21 and assembled, and at the same time, the pivoting lever 22 is mounted into the fitting hole 21a formed in the cover 21 to operate the locking unit installed in the base 20. .

In addition, the locking unit is provided with a first locking portion (25) which slides in association with the operation of the pivoting lever (22) at the center portion on the base (20), and the first locking portion (25) is a pivoting lever. An operating piece 26 operated by the 22 and a horizontal moving piece 27 configured to operate in the horizontal direction when the operating piece 26 is rotated so that the fastening piece 27a emerges from the base 20 to the outside. And a vertical movable piece 28 configured to slide in the vertical direction in conjunction with the horizontal movable piece 27.

A protruding pin 29 is formed at the end of the arm 26a of the operation piece 26 to be retained in the locking hole 27b of the horizontal moving piece 27 and at the same time a U-shaped long hole formed in the horizontal moving piece 27 ( 27c) is configured to be guided to the body side of the operation piece 26, the inclined hole (28a) formed on both vertical movement piece 28 is equipped with fixing pins (30a) at both ends of the horizontal moving piece (27) ) Is assembled into.
