Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a locking device for metal fittings in which four shoji screens are inserted into a window frame in a sliding manner.

Prior Art A conventional four-drawing sash is locked with a crescent at the joining part of each inner and outer shoji. It is known that the fourth shoji of the shoji and the third shoji of the butt shoji are each locked with a crescent.

Problems that the invention aims to solve In such conventional locks, if the crescent is unlocked and the second and third shoji of the butt shoji can be opened and closed, the first and fourth shoji of the doorstop shoji can be opened and closed. Since the door can be opened and closed freely, there was an inconvenience that the doorstop shoji would also move little by little while the butt shoji was being opened and closed. Furthermore, it was not possible to fix only the doorstop shoji or only the butt shoji.

Means for Solving the Problems Therefore, the present invention is to attach a lock to the doorstop shoji to lock it with the vertical frame, so that the doorstop shoji can be locked individually on the indoor side, and one side of the butt shoji is attached to the other. A lock is provided to lock the abutting shoji, so that the abutting shoji can be mutually locked on the indoor side, and a protrusion is formed in advance on the vertical stile of the abutting side of the abutting shoji on the outdoor side of one of the stiles. In addition, a recess is formed in the other stile to swallow the protrusion, and a tight material is attached to the recess so that the protrusion comes into contact with the tight material when the shoji is closed. The doorstop shoji can be individually locked, and the butt shoji can be locked while maintaining airtightness from each other.

Embodiments The present invention will be described below based on illustrated embodiments.

In Fig. 1, the present invention is equipped with sliding door shoji 1, 1 on the outdoor side of the window frame W that can be drawn on both sides, and butt shoji 2, 3 that are drawn toward the center on the indoor side, respectively. Assuming a 4-panel shoji window.

The door stopper shoji 1 and the butt shoji 2, 3 are engaged with each other at the joining part, and the door stop shoji 1, the vertical frame 5, and the butt shoji 2, 3 are each lockable by a locking device 4. ing.

The lock device 4 has a lock housing 4 as shown in FIG.
1, an operating rod 43 that protrudes outward from a vertical hole 42 provided in one side wall of the housing and is movable up and down; A lock rod 44 that moves in the vertical direction and has a downward L-shape at its tip 45.
and a plate-shaped lock receiver 46 having a vertical hole 47 into which the tip end 45 of the lock rod is inserted and engaged.

Further, between the door stop shoji 1 and the vertical frame 5, the lock housing 41 is placed so that the operating rod 43 of the lock device 4 is located on the indoor side and the lock rod 44 faces toward the vertical frame 5. It is attached to the vertical stile 11 of the butting shoji 1, and the lock receiver 46 is attached to the vertical frame 5, and between the butting shoji 2 and 3, the operating rod 43 of the locking device 4 is located on the indoor side and the locking rod Lock housing 41 with 44 facing in the direction of the other butt shoji 3
is attached to the vertical stile 21 of one butt shoji 2, and the lock receiver 46 is attached to the vertical stile 31 of the other butt shoji 3.
It is installed on.

In this case, the lock housing 41 is installed inside each vertical stile 11, 21 of the doorstop shoji 1 and the butt sash 2, and appropriate window holes are formed in the walls of the vertical stile as necessary, and these windows are The operating rod 43 and lock rod 4 are inserted through the hole.
4 will appear. 3 to 5, unlike the case of the above example, a lock housing 41 is attached to the vertical stile 31 of the butt shoji 3 on the opposite side, and a lock receiver 46 is attached to the vertical stile 21 of the other butt shoji 2. An example is shown in which the is installed. Moreover, FIGS. 6 and 7 show a doorstop shoji 1 with a lock housing 41 attached to the vertical stile 11 and a lock receiver 46 attached to the vertical frame 5,
In these cases, the lock 46 is basically a vertical hole 47.
However, since the tip 45 of the lock rod 44 is inserted into and engaged with the vertical hole 47, the lock receiver 46 is shaped like a horizontal U-shape (Fig. 6) or a vertical C-shape (Fig. 6). 3 and 7), and a predetermined clearance is provided between the vertical frame 5 and the vertical frame 5. Furthermore, the present invention forms a protrusion on the outdoor side of one of the butt-side vertical stiles 21 and 31 of the butted shoji 2 and 3, and forms a recess that swallows the protrusion in the other stile, Further, a tight material 6 is attached to the recessed portion so that the protruding portion comes into contact with the tight material 6 when the shoji is closed. 1st
In the figure, a protrusion 22 is formed on the vertical stile 21 of the left side butt shoji 2, while a recess 33 is formed on the vertical stile 31 of the right side butt shoji 3, and the tight material 6 is attached to this. In the case of FIG.
On the other hand, the vertical stile 21 of the left butt shoji 2
A recess 23 is formed in the recess 23, and the tight material 6 is attached to the recess 23.

Effects of the invention Since the invention is constructed as described above, if the locking device of the invention is attached to four shojis, the first and fourth shojis of the doorstop shoji can be completely fixed, and the butt shoji Only the second and third shoji can be opened and closed, and the door shoji can be fixed individually or opened and closed, so that the door shoji can be turned into a butt shoji, and the butt shoji can be turned into a door shoji. It is not affected by the opening and closing of the hit shoji. Moreover, the locking device of the present invention can be installed by simply drilling a suitable window hole in the vertical stile of the shoji, attaching the lock, and attaching a lock catch for the lock bar to the vertical frame facing the vertical stile. It is also easy to do, and the security effect can be improved by double locking the four-panel shoji with crescents. In addition, the locking device of this proposal is between the doorstop shoji and the vertical frame.
Since it is installed between butt shoji, it does not interfere with the opening and closing of the shoji, and airtightness can be maintained by the presence of the tight material between the butt shoji. In addition, when a sash with this locking device is used in conjunction with other sashes as a double sash, each doorstop shoji or butt sash can be opened and closed independently, thus eliminating unnecessary opening and closing of other sashes. Therefore, the inflow of air inside and outside is reduced, and heat retention and insulation effects can be expected.
