According to the present invention, by inserting the lining member from the mounting opening of the frame, the lining portion can be interposed between the inner surface of the frame and the operating mechanism to fill the gap between the two.

Further, in the above lock device, the fastening means is configured to include a lock lever slidably supported on a depth surface of the frame, and a lock lever provided on the lock lever and sliding along the lock lever And moving, thereby changing a lock pin that is opposite to a lock seat provided in the open frame; and in the snapping state, the lock pin is disposed opposite to the lock seat in a state in which the window is closed a position in which the lock pin abuts against the lock seat, thereby restricting movement of the pull window in the direction of opening, and on the other hand, in the non-fastened state, the lock is locked in a state of closing the window The pin is disposed at a position retracted from the lock seat.

According to the present invention, by causing the lock pin to abut against the lock seat of the open frame, the sliding window can be restricted from moving in the opening direction.

Further, the door and window system of the present invention employs the lock device of any of the above items between the opening frame and the frame.

According to the present invention, the same operational effects as the above-described lock device can be achieved.

According to the present invention, by inserting the lining member from the mounting opening of the frame, the lining portion can be interposed between the inner surface of the frame and the operating mechanism to fill the gap between the two. Therefore, the assembly work can be prevented from being complicated, and the operation mechanism can be held on the inner surface of the frame. Therefore, the operation mechanism can be satisfactorily operated to ensure the correct operation of the lock device.

When the operation mechanism 130 is to be attached to the left vertical frame 23a, the component case 131 is inserted into the left vertical frame 23a from the mounting opening 26, and the coupling pin 137 is fitted into the coupling hole 122 of the lock lever 120. In the state, the cover mounting screw 139 is locked to the mounting screw hole 27 of the left vertical frame 23a through the mounting screw retracting hole 135d formed in one of the front cover 135, and is widened on the indoor side frame of the left vertical frame 23a. 23a2 can be installed with the handlebar 30.

At this time, according to the door and window structure, since the component box 131 is offset with respect to the front cover 135, when the direction of the action mechanism 130 is reversed with respect to the mounting opening 26, the front cover 135 cannot be inserted. Between a pair of curved portions 25b. Thereby, even if the component case 131 is attached upside down with respect to the left vertical frame 23a, the component case 131 can be constantly arranged at a predetermined position with respect to the inner surface 23a3 of the left vertical frame 23a.

Further, since the slider 136 is disposed outside the left vertical frame 23a, the operation of fitting the coupling pin 137 of the slider 136 to the coupling hole 122 of the lock lever 120 may be performed in the left vertical frame 23a. The external work is performed, and the assembly work of the lock device 100 can be performed extremely easily.

Further, in the door front face 23a1 of the left vertical frame 23a, a pair of slider guides 25 are provided. Therefore, the mounting opening 26 cannot be provided unless it is at a position avoiding the slider guide 25. In other words, in the left vertical frame 23a, as shown in the cross section of Fig. 10-1, the opening position on the indoor side of the mounting opening 26 cannot be matched with the inner surface 23a3 of the left vertical frame 23a, but has to be The inner surface 23a3 of the left vertical frame 23a is disposed on the outdoor side. When the component case 131 is simply inserted into the mounting opening 26 with respect to the left vertical frame 23a, a gap is formed between the component case 131 and the inner surface 23a3 of the left vertical frame 23a.

Therefore, in the door and window structure, as shown in Figs. 10-1 to 10-3, the lining member 140 is attached to the mounting opening 26 of the left vertical frame 23a in advance, and the assembly box 131 is left. The inner surface 23a3 of the vertical frame 23a is filled between. As shown in FIG. 3-1, the lining member 140 is formed by arranging a substantially rectangular lining portion 140a and a pair of engaging portions in a direction separating from both ends of the base end portion of the lining portion 140a. The 140b is integrally formed of a metal member. The inner lining portion 140a has a width slightly shorter than the length in the upper and lower directions of the mounting opening 26 formed in the left vertical frame 23a, and is appropriately curved in the out-of-plane direction, and is formed as shown in Fig. 10-2. When the one surface 140a1 is brought into contact with the inner surface 23a3 of the left vertical frame 23a, the other surface 140a2 is disposed so as to extend over the opening edge of the indoor side of the mounting opening 26. In the lining portion 140a, a notch 140c is formed in a portion corresponding to the drive shaft insertion hole 28 formed in the indoor side frame wide surface 23a2 of the left vertical frame 23a, and corresponds to a pair of handle mounting holes 29.
