Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash and, more particularly, to a sash having an improved sublock structure. [0002] Generally, a sash, for example, a pull sash,
A frame including an upper frame, a lower frame, and right and left vertical frames, inner and outer sliding doors provided to be openable and closable within the frame, and a crescent as a main lock (main lock) for locking the sliding door in a closed state. And Further, in order to enhance security, there is also known a device provided with a sublock (auxiliary lock) in addition to the crescent. An example of the sublock is described in, for example, Japanese Utility Model Laid-Open Publication No. 56-89865. [0003] The sublock is mounted on the inner surface of the outer sash, and a person who tries to enter the room from the outside breaks the glass by unlocking the crescent by protruding the lock body to the inner side of the sash. Even if the user tries to open the sash, the lock body abuts on the inner sash like a stick, so that the sash cannot be opened and illegal intrusion can be prevented. [0004] Incidentally, in the above-mentioned sublock, an external force (including an impact force) for opening the shoji is supported by a lock body protruding from the indoor surface of the shoji to the indoor side. In view of the structure, it is necessary to secure the thickness of the lock body in order to increase its strength, and the entire sublock including the case for accommodating the lock body tends to have a large thickness dimension (expected dimension). For this reason, it has been difficult to mount the sublock on a sash, such as a resin sash, in which it is difficult to secure a mounting space for the sublock. On the other hand, when the sublock is formed to have a small thickness, the thickness of the lock body becomes thin and the strength is reduced. It becomes easy to bend or break more than the protruding position (protruding amount), and there is a problem that the durability of the sublock is reduced. The present invention has been made in consideration of the above circumstances, and has as its object to provide a sash capable of improving the strength of a lock body, improving the durability of a sublock, and reducing the thickness dimension.

Therefore, the sublock 1
2 is formed to have a small thickness so as to fit in the space. As shown in FIG. 10, the interior surface of the lower frame 6b has a double structure having an outer surface portion 6x and an inner surface portion 6y with a small space therebetween, so that the outer surface portion 6x and the inner surface portion 6y are provided.
The mounting hole 37 is formed across the. A flange 38 is formed on the upper edge of the case 13 of the sublock 12 so as to abut the outer edge of the mounting hole 37 from the outside (inside of the room). In order to mount the sublock 12 in the narrow space, a steadily mounting structure in which the case 13 of the sublock 12 is steadily mounted, and a one-side fixing structure in which one end of the case 13 is fixed by a screw 39 as a fixing tool. Has been adopted. In this case, the mounting hole 37 is formed to have a size that accommodates the case 13 movably in the longitudinal direction (left-right direction). At one end (the right end in FIG. 10) of the case 13, an outer surface protruding portion 40 that protrudes in the longitudinal direction continuously from the flange portion 38 is formed, and the outer surface portion 6 x and the inner surface are protruded from the mounting hole 37. An inner projection 41 that is inserted into the gap 6s of the portion 6y and sandwiches the outer surface 6x with the outer projection 40 is formed. At the other end (left end) of the case 13, the outer surface 6 x and the inner surface 6
An inner flange portion 42 that is inserted into the gap 6s of y and that sandwiches the outer surface portion 6x with the flange portion 38 is formed. When the sublock 12 is mounted in the mounting hole 37, the case 13 is first moved in the direction of arrow F (rightward) in FIG. The case 13 is inserted into the gap 6s of 6y, and the case 13 is housed in the mounting hole 37. Next, the case 13 is moved in the direction of arrow R (left direction) until it contacts the left end of the mounting hole 37,
The outer surface 6x between the flange 38 and the inner flange 42 of the case 13
Is positioned so as to sandwich it. In this way, when the case 13 is attached to the attachment hole 37 in a left-right manner, and positioned at the left end of the attachment hole 37, the screws 39 are provided so as to extend from the outer protrusion 40 to the outer surface 6 x and the inner protrusion 41.

The hole 43 is preferably formed larger than the screw diameter of the screw 39 in order to escape burrs generated from the outer surface 6x when the screw 39 is screwed. Accordingly, it is possible to prevent a problem that burrs generated from the outer surface portion 6x enter between the outer surface portion 6x and the outer surface projecting portion 40 and cause the outer surface projecting portion 40 to float. Further, only one end of the case 13 is fixed with the screw 39, and the screw 39 is hidden by the inner sash 2 and is not exposed to the indoor side, so that the design can be improved. Furthermore, the outer projection 40 at one end in the longitudinal direction of the case 13 and the flange 38 at the other end may be caught on the airtight material (not shown) of the inner sash 2 at the time of opening and closing the sash, thereby damaging it. It is preferable that it is formed in a curved shape as much as possible. Next, the operation of the slip sash having the above configuration will be described. When going out or going to bed, the sashes 2 and 3 are closed, the crescent 11 is locked, and the sublock 12 is locked. The locking of the sublock 12 can be performed by operating the operation part 24 of the first lock body 14A in the direction of the arrow 23, whereby the rotation regulating shaft holding the first lock body 14A at the storage position in the case 13 is achieved. The engagement between the first lock body 14A and the engaging portion 18a of the first rotation restricting hole 18 is released, and the first lock body 14A is
And protrudes from the inside of the case 13 to the outside, that is, to the indoor side. In the projecting process, first, the first lock body 14A
