Description

Lock for sliding windows. {LOCK DEVICE FOR A SLIDING WINDOW}

The present invention relates to a locking device for a window, and more particularly to a sliding window locking device that can prevent the intrusion of the outside while being able to ventilate the internal air by opening a part in the sliding window.

In general, the sliding window is opened and closed while the front window and the rear window move in parallel to each other inside the window frame as a locking means, the locking piece is attached to the center of the inner frame of the rear window and attached to the front window to rotate the hook In addition, the locking lever with the hook formed on the upper part or the lower part of the frame can be attached to the shaft to be elasticized by the spring. There is a lock that is installed in the door frame and locked. However, in the conventional lock device as described above, when the window is opened for the purpose of ventilation, the lock device is released so that the door can be easily opened from outside and invaded and always exposed from theft. Therefore, the window must be firmly closed and locked at home or at bedtime, which prevents the ventilation of indoor air and increases the energy consumption of the heating system in summer. And, sometimes, a separate security window is installed, which is expensive and expensive, and tends to damage the appearance.

For the purpose of solving such a problem, the present invention has been proposed a lock device for sliding windows, which was filed on February 21, 2000, and the utility model registration application No. 2000-1085 by the same person. However, they increase the manufacturing cost due to the complexity of the structure and the large volume, and are difficult to attach to the limited window frame. In addition, the fixed position in the open state of the window is limited, but the problem is that the window is not free.

Accordingly, an object of the present invention is to provide a locking device for a sliding window that can always be locked even if the window is opened for ventilation to prevent theft from outside intrusion.

Another object of the present invention is to provide a lock device for a sliding window that is easy to attach to the window frame as the lock device is downsized, and usability is increased as the window can be opened and fixed in multiple stages.

And, Figure 4 is a cross-sectional view of the center of the lock device of the present invention, Figure 5 is a perspective view of the lock device is attached to the window frame of the front window and the window frame of the rear window.

According to the drawing, the winch 20 on which the wire 26 is wound and the casing 50 for assembling the frame 10 having the stopper on the upper surface are fitted to the fixed plate 60 and the actuator 1 is completed. It is attached to the side of the left side window frame 3a of the window 3, and the fixture 2 which has a hole 2a in the center is attached to the inner side of the right side window frame 3a of the rear window 3. .

In more detail above, in the frame 10 having the front open in FIG. 1 and having the incision hole 18 horizontally in the center of the left side, and having the holes 16 and 16a in the center of the upper and lower surfaces, While bending inward, rectangular recesses 12 and 14 are formed, respectively. Here, the stopper 30 having the ratchet 34 bent downward while the upper recessed part 12 extends forward is placed, and the square with the shaft 40 attached to the center as the lower recessed part 14. As the plate body 44 is attached, the square plate body 44 is fitted to the lower recess 14 of the frame 10 so that the shaft bar 40 does not rotate. The shaft bar 40 has an incision groove 42 cut in the center from the top to the bottom, and is inserted into the upper hole 16 through the lower hole 16 'of the frame 10. At this time, the winch 20 and the coil spring 46 are fitted to the shaft 40 in the frame 10. The winch 20 has a hole 24 for fitting the shaft 40 to the center. The wire 26 is wound to the outside and the ratchet wheel 22 having a predetermined latching jaw 22a formed thereon is integrated. In addition, the coil spring 46 is located at the lower portion of the winch 20, the inner end is fixed to the cutting groove 42 of the shaft 40, and the outer end is fixed to the winch 20. As such, the coil spring 46 has an elastic force to restore the winch to its original position when the winch 20 is rotated. On the other hand, the stopper 30 has a handle 32 is assembled on the upper surface, the projection 38 on one side of the front and the spring 36 is fitted in the front of the projection 38 and the frame 10 the stopper 30 Is pushing backwards. At this time, the front ratchet 34 of the stopper 30 is positioned in front of the upper ratchet wheel 22 of the winch, and the latching jaw 22a of the ratchet wheel is in close contact with the side of the ratchet 34 and the winch 20 The rotation is stopped. A connecting plate 28 having a locking jaw 28a is attached to an end of the wire 26 wound around the winch 20. Next, an outer side of the frame 10 has a casing 50 in which a rectangular hole 54 is provided on the upper surface thereof so that the handle 32 of the stopper 30 protrudes. The casing 50 has an opening portion 52 on the left side thereof, so that the connecting plate 28 can be positioned to the foremost front, and a bracket 56 that extends outward at the upper end and the lower end of the casing 50. In addition, there is a fixing plate 60 attached to the window frame 3a at the rear of the casing 50. The fixing plate 60 has a guide groove 62 formed at an upper end and a lower end thereof, and a bracket of the casing 50 is formed. 56 is entered from one side and assembled. Therefore, the casing 50 may be moved left and right from the fixing plate 60.

On the other hand, the fixing body 2 attached to the window frame 4a of the rear window 4 has a square hole 2a at the front and a bracket 2b bent at one side at the rear, and the bracket 2b is formed. The back of the) is attached to the window frame (3a) with screws.

Referring to the operating state of the lock device for a sliding window designed in this way as follows.

The present invention is that the actuator (1) and the fixture (2) is attached to each front window and the rear window to completely lock the window or no longer open, the actuator (1) is a front window (3) It is assembled to the left side of the window frame of the window located in the front of the room, the fixing body 2 is attached to the right window frame of the rear window (4). At this time, the actuator (1) and the fixture (2) should be at the same horizontal position, it is preferable to attach to the lower end of each window so that the operational convenience and the wire 26 is not exposed.

Next, the wire 26 wound around the winch 20 of the actuator 1 is pulled out as shown in FIG. 2 and the catching jaw 28a of the connecting plate 28 is removed from the hole of the fixture 2. In this case, first, open the window slightly and push the casing 50 of the actuator 1 immediately after the rear window frame 4a is removed from the front window frame 3a. The locking jaw 28a of the connecting plate 28 is brought into contact with the fixing body 2 by moving backward along the guide groove 62 of the fixing plate 60. After the window is opened continuously, the catching jaw 28a is inserted into the hole 2a of the fixing body 2 and the wire 26 of the winch 20 is released when the front window is opened. At this time, the wire 26 is pulled out to the left in the state attached to the window frame, that is, the handle 32 of the stopper 30, in other words, it is possible to withdraw the wire 26.

As such, when the handle 32 is pushed to the left side, as shown in FIG. 3, the ratchet 34 is released from the ratchet wheel 22, and the winch 20 is free to rotate and open the window as desired. When the hand 32 is released, the stopper 30 returns to the elastic force of the spring 36 and the latching jaw 22a of the ratchet wheel 22 is caught by the ratchet 34 to fix the winch. Therefore, the window does not open unless the handle 32 is removed from the room.

As described above, the present invention is that even if you open as many windows as you want, the position is always locked to prevent intrusion from the outside, without having to install a security window that damages the appearance at a high cost It can relieve anxiety from intrusion and can always freely ventilate the room air. Especially small size and light weight, it is not easily exposed from the outside, and usability is more convenient.
