Description

Locking device for mounting double-layer glass and double-layer glass door including the same {DOOR LOCK DEVICE MOUNTED ON MULTI LAYERED GLASS AND MULTI LAYERED GLASS DOOR HAVING THE SAME}

An embodiment of the present invention relates to a double-glazed glass door, and more specifically, to a locking device that can be mounted on the double-glazed glass of a double-glazed door that can swing inside or out.

Recently, double-glazed doors have been developed that use at least two tempered glass plates and a spacer to create an air layer between the tempered glass plates. Compared to single glass doors, such double-layer glass doors have the advantage of significantly reducing the amount of heat energy escaping to the outside and providing excellent insulation and noise blocking properties.

For example, a double-glazed door is made of two sheets of tempered glass and a metal door frame, and can be divided into sliding type and swing type.

Among these, the swing-type double-glazed door is a swing-type door that can be opened and closed in both indoor and outdoor directions, and is hinged at the top and bottom of the door frame so that it can rotate both indoors and outdoors.

Here, in the swing-type double-glazed door, the door frame is composed of a lower frame supporting the lower part of the tempered glass plates, an upper frame supporting the upper part of the tempered glass plates, and a side frame supporting both sides of the tempered glass plates.

Meanwhile, the swing-type double-glazed door as described above is equipped with a locking device that allows it to be locked or opened with a key indoors or outdoors.

Typically, the locking device for a double-glazed door is installed on one of the upper frame, lower frame, and side frame of the door frame. This locking device can lock the door by, for example, inserting a key into a key cylinder and rotating the key cylinder, thereby inserting a locking bar into a fixing hole at the top or bottom of the door frame by the key cylinder.

In the prior art, in order to mount a locking device on a door frame as described above, it is necessary to increase the size (or area) of the upper frame, lower frame, or side frame of the door frame.

However, recently, slim door frames have been applied to double-glazed doors to provide users with a smooth swing feeling of double-glazed doors, but it is difficult to install a locking device on such a slim door frame, so it is actively responding to recent consumer trends.

Hereinafter, the operation of the double-glazed glass mounting locking device 100 configured as above and the multi-layered glass door 200 including the same will be described in detail with reference to FIGS. 1 to 8.

First, in an embodiment of the present invention, the spacer 20 is connected to the first and second plates through the first mounting hole 1a of the first pane 1 and the second mounting hole 2a of the second pane 2. It is arranged between the panes 1 and 2.

And, in an embodiment of the present invention, the outer door lock assembly 30 and the inner door lock assembly 50 are fastened to each other with the spacer 20 therebetween. Here, the outer door lock assembly 30 is disposed at the edge of the first mounting hole 1a of the first pane 1, and the inner door lock assembly 50 is located at the edge of the first mounting hole 1a of the second pane 2. It is placed at the edge of the mounting hole (2a).

According to the locking device 100 for mounting a double-glazed glass according to an embodiment of the present invention mounted on the first and second panes 100 as described above, the outer door lock can be locked outdoors with the double-glazed door 200 closed. A key is inserted into the key cylinder 33 of the assembly 30, and the key cylinder 33 is rotated in one direction through the key.

Then, the joint lever 35 rotates in one direction by the rotation of the key cylinder 33, and the door lock lever 53 of the inner door lock assembly 50 rotates in one direction by the joint lever 35. It is rotated.

In this way, when the door lock lever 53 rotates in one direction, the rotation lever 55 is rotated in one direction by the door lock lever 53. And, as the rotation lever 55 rotates in one direction, the latch member 57 moves in one direction (for example, upward direction) while the pair of lever locking legs 63 interfere with the rotation lever 55. is rotated.

Therefore, by rotating the latch member 57, the locking slider 71, locking rod 73, and striker pin 75 of the locking unit 70 are connected to the main support member 15 of the other side frame 14. It slides upward along the guide hole 18b.

As a result, the striker pin 75 of the locking unit 70 is inserted into the door frame 5 in the upward direction, and thus the double-glazed glass door 200 can be locked to the door frame 5.

Meanwhile, according to the locking device 100 for mounting a double-glazed glass according to an embodiment of the present invention, the door of the inner door lock assembly 50 is opened by operating the handle lever of the user indoors with the double-glazed door 200 closed. When the lock lever 53 is rotated in one direction, the double-glazed glass door 200 can be locked to the door frame 5 through a series of actions as described above.

On the other hand, according to the locking device 100 for mounting double-glazed glass according to an embodiment of the present invention, the double-glazed glass door 200 is locked to the door frame 5 as described above, and the outer door lock assembly is installed outdoors. Insert a key into the key cylinder (33) at (30), and use the key to rotate the key cylinder (33) in the other direction.

Then, the joint lever 35 is rotated in the other direction by the rotation of the key cylinder 33, and the door lock lever 53 of the inner door lock assembly 50 is rotated in the other direction by the joint lever 35. rotated in the direction

In this way, when the door lock lever 53 rotates in the other direction, the rotation lever 55 is rotated in the other direction by the door lock lever 53. And, as the rotation lever 55 rotates in the other direction, the latch member 57 moves in the other direction (for example, the lower side) while the pair of lever locking legs 63 interfere with the rotation lever 55. direction) is rotated.

Therefore, by rotating the latch member 57, the locking slider 71, locking rod 73, and striker pin 75 of the locking unit 70 are connected to the main support member 15 of the other side frame 14. It slides and moves downward along the guide hole 18b.

Accordingly, the striker pin 75 of the locking unit 70 moves downward from the door frame 5 and the double-glazed glass door 200 can be unlocked from the door frame 5.

On the other hand, according to the locking device 100 for mounting double-glazed glass according to an embodiment of the present invention, the double-glazed door 200 is locked to the door frame 5 and cannot be operated indoors by the user's handle lever. When the door lock lever 53 of the inner door lock assembly 50 is rotated in the other direction, the double-glazed glass door 200 can be unlocked from the door frame 5 through a series of actions as described above. .

The locking device 100 for mounting double glass according to an embodiment of the present invention as described so far can be mounted on the first and second panes 1 and 2 of the double glass door 200.

Therefore, in the embodiment of the present invention, unlike the prior art in which the locking device is mounted on the door frame, the locking device 100 is mounted on the double-glazed glass, so that the door frame 10 of the double-glazed door 200 can be used by recent consumers. You can slim down according to the trend.

As a result, in the embodiment of the present invention, the beautiful appearance of the double-glazed glass door 200 can be secured, and a smooth swing feeling of the double-glazed glass door 200 can be provided to the user.

Although the embodiments of the present invention have been described above, the technical idea of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the technical idea of the present invention will understand the configuration within the scope of the same technical idea. Other embodiments can be easily proposed by adding, changing, deleting, or adding elements, but this will also be said to fall within the scope of the present invention.
