Description

[Detailed Description of the Invention] Technical Field This invention relates to a locking device for double glass shoji screens.

Conventional technology A double-glazed shoji with a blind inside the double-glazed glass has improved heat insulation, sound insulation, and sunlight shielding performance, and when used conventionally, the inner and outer glass shoji are configured to be able to slide horizontally relative to each other. Since both glass shoji were locked by screwing them together, opening and resetting the shoji was troublesome.

Purpose of the invention This invention was made with attention to the above-mentioned problems, and it not only provides a locking device for double glass shoji that can easily open and reset the inner and outer glass shoji of double glass shoji. The expected width of a double glass shoji screen, which conventionally tends to be wide due to the interior of the blind, is hardly increased despite the installation of a locking device.

Structure of the invention In order to achieve this purpose, this invention is a double glass shoji in which an outer shoji and an inner shoji are attached so that they can move laterally relative to each other. It has a guide surface and a locking protrusion, is biased by a spring, rotates toward the vertical stile of the other opposing shoji when both shoji are assembled, and locks into the engagement hole provided in the vertical stile. A locking device including a locking member that locks both shoji screens by engaging protrusions, and a locking device that is rotatably arranged near the locking device and locks while engaging with a guide surface of the locking member. and a lock release member that rotates in a counter-locking direction that intersects with the aforementioned rotational direction of the member, and rotates the locking member in the opposite direction against the biasing force of a spring to release the lock. A configuration consisting of the following is adopted.

As shown in FIG. 6, the release portion 42 is normally engaged with the outer surface of the locking protrusion 34a of the locking member 34, which is fitted into the side wall of the vertical stile 15a, to place the locking member 34 in the locked position. keeping. The locking device 31 and the lock release member 41
A locking device is constituted by the above.

Reference numeral 44 shown in FIG. 9 is a locking device provided at the lower part of the vertical stile 15a, and 45 is a lock release member, both of which are similar to the locking member 34 described above.
Since the configurations of the lock release member 41 and the lock release member 41 are upside down, a description thereof will be omitted.

The operation of the lock device constructed as described above will be explained.

Now, as shown in Figure 3, double glass shoji 5
In this step, the outer shoji 7 and the inner shoji 8 are combined with each other, and the locking protrusion 35 of the locking member 34 is engaged with the locking hole 30 of the inner shoji 8, and the inner shoji 8 is released from the locked state. To do this, first, the operating portion 43 of the lock release member 41 is rotated upward in the direction of the arrow as shown in FIG. 6b. Then, the release part 42 presses and slides on the guide surface 37, whereby the locking member 34 is retracted and rotated in the anti-locking direction (in the direction of the arrow in FIG. 7a) while resisting the biasing force of the spring 39. Ru. As a result, the locking protrusion 35 of the locking member 34
is released from the locking hole 30. Furthermore, the release section 42
As is clear from the above description, the locking member 34 is completely unlocked when the locking member 34 is rotated downward and engaged with the locking stepped portion 36. While the unlocking member 41 rotates in a direction parallel to the surface of the double glass shoji 5, the locking member 34 is released when the guide surface 37 is pushed by the releasing portion 42. 41, that is, in a direction perpendicular to the surface of the double glass shoji 5, the space for installing the locking device is small enough to allow the rotation of the locking member 34. Since only a small amount is required, the expected range hardly increases. Note that at this time, the locking member 34 is elastically engaged with the release portion 42 by the biasing force of the spring 39, so that this state is maintained.

Subsequently, the locking device 44 located at the lower position is also unlocked in the same manner using its lock release member 45. However, the operating portion 43 of the lock release member 45 is assumed to rotate downward in the opposite direction to the lock release member 41.

After unlocking both the lock release members 41 and 45 as described above, if the inner shoji 8 is moved to the right as shown in FIG. 9 while keeping the locks released as shown in FIG. The glass shoji 5 is opened.

Next, in order to close the inner shoji 8 from the open state, first, the lock release members 41 and 45 are rotated in the opposite direction to return the operating portion 43 to its original position along the vertical stile 15a. Then, the locking member 34 of the locking device 31 is rotated by the spring 39, and the locking protrusion 35 is rotated by the spring 39.
is exposed to the outside through the through hole 29. After that, when the inner shoji 8 is moved to the left in the opposite direction to the above, the left side of the vertical stile 20a of the inner shoji 8 comes into contact with the guide slope 38 of the locking protrusion 35 of the locking member 34, but the inner shoji remains as it is. 8 to the left, the locking member 34 is pressed by the vertical stile 20a and rotates in the anti-locking direction (in the direction of the arrow in FIG. 7a) while resisting the biasing force of the spring 39.

When the locking hole 30 of the vertical stile 20a corresponds to the through hole 29, the locking member 34 is fitted into the locking hole 30 by the spring 39. As a result, the inner shoji 8 is locked by the locking protrusion 35 of the locking member 34.

By releasing the lock release member 41 in this manner, the locking member 34 is easily released from the locked state, and the inner shoji 8 that has been opened can be easily locked when resetting it again.

Note that this invention is not limited to the above-mentioned embodiment, and for example, the guide slope 38 of the locking member 34
may be omitted. However, in this case, when resetting the inner shoji 8 from the open state, the lock release members 41 and 45 are moved to the locking member 3 as shown in FIG.
4 and held in the unlocked position.

Effects of the invention As detailed above, this invention is a double glass shoji in which an outer shoji and an inner shoji are attached so that they can move laterally relative to each other, and the invention is attached to the vertical stile of either the inner or outer shoji. a locking device comprising a locking member having a guide surface that engages with a vertical stile of the other opposing shoji to lock both shojis when the two shojis are assembled;
The locking device is rotatably disposed near the locking device, and rotates the locking member in a counter-locking direction that intersects the rotation direction while engaging with a guide surface of the locking member to release the lock. By being constructed with a lock release member, it is not only possible to easily open and set the inner and outer glass shoji of the double glass shoji, but also to minimize the increase in the expected width of the double glass shoji due to the installation of the locking device. It is an excellent idea for industrial use, and it has excellent effects that can limit the amount of water used.
