A spring 26 is fitted to the circumferential surface of the rod 20, and the spring 26 causes the rod 16 moved backward by the tensioning force to be moved forward again by the tension force. do.

The one-way clutch plate 28 is engaged with the wing piece 22a of the above-described rotating plate 22 to selectively rotate the rod 16 in only one direction, and as necessary, in FIG. As shown in the figure, one end of the one-way clutch plate 28 moves forward according to the pressing operation of the exposed part in the state exposed to the outside of the case 14, and moves backward by the tension of the spring 32. The rotating plate 22 is rotated in both directions (forward and reverse rotation) by returning. That is, an opening 30 is formed at a lower end of the one-way clutch plate 28, and the opening 30 is a blade of the rotating plate 22 when the one-way clutch plate 28 moves forward. Since it is located on the same line as the piece 22a, the rod piece 22a is passed to allow the rod 16 to rotate forward and backward, and when the one-way clutch plate 28 moves backward, the opening 30 ) Is spaced apart from the wing piece (32a) to block the passage of the wing piece (32a) to rotate the rod 16 in one direction only.

The push bar 34 is formed vertically in the state in the case 14, the upper end is exposed, the tilting plate 36 is moved up and down in accordance with the pressing operation of the exposed portion.

The tilting plate 36 has a cross section having a “b” shape and is installed below the rod 16, and the tilting plate 36 has a hinge provided at one side according to the operation of the push bar 34. The rod 16 is moved rearward by rotating about 38.

The guide hole 44 is formed to extend in the longitudinal direction in the center of the housing 42, the guide hole 44 is moved left, right of the rod 16 provided in the lock member 12 described above. Will guide you. In addition, the upper portion of the guide hole 44 is formed with a plurality of engaging grooves 46 in the form of a saw, the engaging grooves 46, the locking projections 18 provided in the rod 16 is selectively It is fitted to restrain the left and right movement of the rod (16). Here, the formation of the plurality of locking grooves 46 in the longitudinal direction of the guide slot 44 will be described later, but the locking protrusions 46 may be caught by the locking slot 46 at any position of the guide slot 44. It is to be able to freely adjust the opening interval of the front window (1) as intended by the user.

The hole 48 is formed at one end of the guide hole 44, the hole 48 is provided in the rod 16, the flange portion 20 which is hanging on the inner surface of the guide hole 44 is The locking member 12 is detached from the fixing member 40 by being inserted into the guide slot 44 or by being pulled out.

Hereinafter, the operation of the lock device for a sliding window of the present invention having the above configuration will be described with reference to FIGS. 1 to 8.

First, the locking member 12 is attached to the side frame (1a) of the front window (1), the fixing member 40 is attached to the window (2a) of the rear window (2) the locking member 12 The rod 16 is inserted into the guide hole 44 of the fixing member 40. That is, as shown in FIGS. 3 and 4, the rod 16 passes through the flange portion 20 of the rod 16 through a hole 48 formed at one end of the guide hole 44. 44, the locking member 12 is coupled to the fixing member 40.

Thereafter, the locking protrusion 18 provided in the rod 16 is locked to any one of the locking grooves 46 of the locking grooves 46 of the guide hole 44, so that the left and the left of the rod 16 are closed. Right movement is constrained, so that the front window 1 is locked.

On the other hand, when you want to open the locked front window (1), as shown in Figure 5 attached to the one-way clutch plate 28 to move forward, the opening 30 of the one-way clutch plate 28 Is located on the same line as the wing piece 24a extending on the top of the rotating plate 22 of the rod 16, so that the rotating plate 22 does not restrain the forward and reverse rotation of the rod 16. do.

Thereafter, when the front window 1 is pulled in the right direction, as shown in FIGS. 6A and 6B, the locking protrusion 18 that is caught in the locking groove 46 of the guide hole 44 is formed of the rod 16. By rotating in conjunction with the forward, reverse rotation, and freely from the locking groove 46, the rod 16 is to move to the right in the guide hole 44 to open the front window (1). In this case, the front window 1 is opened by a plurality of locking grooves 46 formed in the guide hole 44 and a locking protrusion caught by any one of the locking grooves 46 of the locking grooves 46. By being made through 18, the opening interval of the front window 1 can be freely adjusted as the user intends, unlike the prior art.

On the other hand, after opening the front window 1 by a predetermined interval as the user intends, as shown in Figure 7 attached to stop the pressing operation of the one-way clutch plate 28, the one-way clutch plate ( 28 moves back to the tension of the spring 32 and returns to the initial state. At the same time, the opening 30 formed in the one-way clutch plate 28 is spaced apart from the wing piece 24a again, so that the wing piece 24a is caught by the one-way clutch plate 28.

That is, when the wing piece 24a is caught, the pivoting plate 22 and the rod 16 rotate only in one direction, and thus the locking protrusion 18 is guide hole 44 as shown in FIG. 8A. By being caught again by the locking groove 46 of the constrained movement of the rod 16, the front window 1 is no longer open in some open state.

At this time, the rod 16 is not impossible to rotate in both directions, as mentioned above, so that it can be rotated in one direction, the locking projection 18 is also shown in Figure 8b, rod 16 in the right direction Is not rotated so as to be caught by the catching groove 46, but may be separated from the catching groove 46 in accordance with the rotation of the rod 16 in the left direction, which closes the partially opened front window 1. The operation (that is, the movement to the left to close) can be freely performed, and the operation of opening the front window 1 any longer is restricted so that the front window 1 cannot be opened arbitrarily from the outside. In other words, the rotation of the rod 16 in only one direction means that the front window 1 moves to the left and the window is closed freely, but the front window 1 moves to the right and the opening of the window is restricted. Will mean. In addition, the rotation of the rod 16 in both directions means moving to the left and right of the front window 1 and freely performing the opening and closing operation of the window.

That is, through the above-described operations, the user can freely open the front window 1 as desired, and after the front window 1 is partially opened as described above, the user can smoothly ventilate the room by restraining the door. Can be, even if you do not use a separate locking means that the front window (1) is to be no longer open in some open state to prevent the intrusion of outsiders. In particular, by forming a plurality of locking grooves 46 in the guide hole 44, the locking projections 18 can be caught in the locking groove 46, no matter which position of the guide hole 44, which is the front The open front window 1 can be fixed in a state in which the opening interval of the window 1 is freely adjusted as the user intends.

On the other hand, when the user wants to completely open the front window (1), the locking member 12 attached to the front window (1) should be separated from the fixing member (40) attached to the rear window (2).

In this case, as shown in FIG. 9, the flange portion 20 of the rod 16 is placed back in the hole 48 formed at one end of the guide hole 44, and then the push rod 34 is moved. When pushed down, the tilting plate 36 tilts about the hinge 38 by the operation of the push bar 34 and moves the rod 16 backward, thus the rod 16 and the flange 20 ) Is separated from the guide hole 44 through the hole 48 as shown in FIG.

That is, as the rod 16 is separated, the locking member 12 is released from the fixing member 40, and thus the front window 1 can be completely opened.

As described above, the present invention achieves many effects as follows.

First, it has the effect of freely adjusting the opening interval of the window of the user.

In addition, even if the opening interval of the window is freely adjusted as described above to maintain the locked state has the effect of preventing the intrusion of outsiders.

In addition, it is possible to fully open the window, if necessary, has the effect of improving the ease of use.
