1 to 3, a handle-integrated window locking device 100 according to a preferred embodiment of the present invention includes a main body case 110, a handle 120, a rotating cam 130, and a moving member 140. , A locking member 150 and a striker 160.

The configuration of the present invention will be described in detail as follows.

First, the main body case 110 is provided with a predetermined storage space so that a plurality of components constituting the window locking device 100 can be configured therein, and an insertion hole 111 penetrating the internal storage space is formed. do. This body case 110 is installed on the window pane 20 coupled to the window frame 10 so as to be slidably opened and closed.

In the handle 120, the drive shaft 121 is rotatably coupled to the insertion hole 111 of the main body case 110. The handle 120 may be opened by turning the drive shaft 121 to the open side of the window 20 with a rotational center when the window 20 is opened.

In this case, the handle 120 is coupled via a torsion spring 123 to return to its original position after the opening operation of the window panel 20 is completed.

The rotation cam 130 is coupled to the front end of the drive shaft 121 inserted in the storage space of the main body case 110, and integrally rotates the drive shaft 121 with a rotational center. An eccentric protrusion 131 is formed to protrude on one side of the rotating cam 130.

The moving member 140 has one side 141 in contact with the eccentric protrusion 131 of the rotating cam 130 that rotates the driving shaft 121 around the rotational center when the handle 120 for opening the window pane 20 is operated. It is operated forward toward the closing direction of the window pane (20).

Specifically, the moving member 140 is selectively inserted into the striker 160, which will be described later, to forward and backward the locking member 150 that sets the locked state of the window pane 20, and the front end of the moving member 140 The inclined surface 143 for manipulating the locking member 150 is provided.

In addition, the moving member 140 is elastically supported in a direction in which the window pane 20 is opened by the first spring 145. That is, the moving member 140 is operated forward in the closing direction of the window panel 20 while being interlocked by the rotation cam 130 when the handle 120 is rotated (counterclockwise in the drawing), and the opening operation of the window panel 20 After completion of this, the instantaneous moving member 140 in which the handle 120 is returned to the original position by the torsion spring 123 is operated backward to the original position by the elastic restoring force of the first spring 145.

4 and 5, the locking member 150 is interlocked with the forward/reverse operation of the moving member 140 to be operated forward/reverse in a horizontal direction orthogonal to the opening/closing direction of the window panel 20, the locking member 150 is elastically supported to the outside by the second spring 155. The locking member 150 is selectively inserted into the striker 160 according to whether or not the moving member 140 is operated to lock/unlock the windows.

In this case, the rear end of the locking member 150 is provided with an inclined portion 151 that slides into contact with the inclined surface 143 of the moving member 140.

Two of these locking members 150 are formed to maintain a solid locking state. Of course, it is not limited thereto, and may be changed and applied to one or two or more numbers.

Referring to FIG. 6, the locking member 150 having such a configuration is orthogonal to the opening and closing direction of the window panel 20 as the inclined surface 143 and the inclined portion 151 come into contact with each other and slide when the moving member 140 moves forward It is operated backward in the horizontal direction of the indoor side, and accordingly, the jamming from the striker 160 is released (refer to FIG. 9).

Conversely, when the external force is released, the locking member 150 is moved forward and fixed to the striker 160 by the elastic restoring force of the second spring 155 (see FIG. 3 ).

The striker 160 is installed on the inner circumferential surface of the window frame 10 that faces when the window panel 20 is closed, and the locking member 150 advances toward the outdoor side by the elastic restoring force of the second spring 155 In the case of operation, a locking hole 161 is provided on the opposite surface so that the tip of the locking member 150 can be inserted and fixed.

In this case, the front end of the locking member 150 contacts the edge portion 160a of the striker 160 when the window panel 20 is closed and slides backward, and then the elastic restoring force of the second spring 155 (refer to FIG. 3). The contact surface 153 is formed to be inclined at a predetermined angle so that it can be inserted and fixed in the locking hole 161.

Meanwhile, on the inclined surface 143 of the moving member 140, the locking member 150 unlocked from the locking hole 161 of the striker 160 when the window panel 20 is opened can be temporarily fixed in a reversed state. A locking projection 144 is provided. In this case, the inclined surface 143 is divided into a first inclined surface 143a and a second inclined surface 143b based on the locking projection 144.

In addition, a locking portion 152 is provided at an end of the inclined portion 151 of the locking member 150 so as to be seated in the locking projection 144.

The operating principle of the moving member 140 and the locking member 150 will be described in detail.

7 to 9, the inclined portion 151 of the locking member 150 is formed by the manipulation of the handle 120 when the window pane 20 is opened, the first inclined surface 143a and the second inclined surface 143b. It is sliding and moving sequentially along the line. As soon as the inclined portion 151 reaches the top dead center P of the second inclined surface 143b, the locking member 150 is unlocked as the tip completely exits from the locking hole 161 of the striker 160 ( Fig. 9 state).

10 and 11, the handle 120 is returned to its original state by the torsion spring 123 after the window pane 20 is unlocked, and the moving member 140 and the locking member 150 interlocked therewith. ) Is returned to its original state by the elastic restoring force of the first and second springs 145 and 155.

At this time, the locking member 150, which has been sliding back from the second slope 143b of the moving member 140 to the first slope 143a, is fixed in its position as the locking portion 152 is caught by the locking projection 144. .

That is, the inclined portion 151 of the locking member 150 is positioned on a horizontal line capable of contacting the edge portion 160a of the striker 160 when the window panel 20 is closed.

In this case, when the locking member 150 is closed, the inclined portion 151 abuts against the corner portion 160a of the striker 160 and is pressed at a predetermined interval t, so as to reach the top dead center (P). At this moment, the locking portion 152 and the locking protrusion 144 are released (in the state of FIG. 9).

In addition, the moving member 140 is returned to its original state by the elastic restoring force as the locking portion 152 is released, and the locking hole of the striker 160 is not caught by the locking member 150. It is inserted into 161 (state of Fig. 6) and is fixed.

In other words, when the window panel 20 is opened, the locking member 150 is not returned to its original state through the structure of the locking protrusion 144, and the position is fixed in a retracted state by a predetermined interval, thereby closing the window panel 20. When the second spring 155 can be compressed again from the beginning, the force of compressing the second spring 155 can be reduced, and accordingly, the window pane 20 can be easily locked without manipulating a separate handle 120.

The handle-integrated window locking device 100 according to the present invention having the above configuration can lock/unlock the window only by opening and closing the handle 120 provided on the window panel 20, and the structure of the locking device 100 Simplifying the manufacturing cost and assembly process can be reduced.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the spirit of the present invention.
