Mechanical locking device for windows{MECHANICAL LOCKING APPARATUS FOR WINDOW}

The present invention relates to a mechanical locking device for a window, and more particularly, by applying a dial-type password input means to the locking device for a window, a mechanical locking device for a window capable of preventing an arbitrary unlocking of the locking device by others It relates to the device.

In general, a security window is installed in a space adjacent to the outside of a building, such as an apartment veranda or a utility room, to prevent intrusion of an outsider, and various types of locking devices are installed on the security window.

However, the conventional locking device installed on the window cannot be operated from the outside, but since it is a structure that anyone can easily open from the inside, children or the elderly who lack cognitive ability can easily unlock the locking device. Therefore, there is a risk such as a fall accident.

In addition, as most of the conventional locking devices installed on windows have a simple structure in the form of a hook, when a specific tool is used or a strong external force is applied, the locking device is arbitrarily released or damaged, thereby preventing external intruders. There is also a risk of theft accident.

In order to solve the problems of the conventional window locking device as described above, in recent years, a locking device or an electronic door lock that is opened through a key is installed. In the former case, there is a risk of loss of the key, and in the latter case, the product Due to the high unit price, economic feasibility declined.

In the body of the control rod 50, three rotation protrusions 52 are formed in a rotatable structure to correspond to the number of the dialing 60 so that they are selectively engaged with the locking protrusions 62 of each dialing 60 to rotate. Is composed.

After setting a predetermined password, as the numbers of the plurality of dialing 60 are arranged to match the set password through the rotation of each dialing 60, the control rod 50 is converted into a state in which it is possible to move up and down. , Since this is a technique known in the art, a more detailed description will be omitted.

The return spring 54 is provided to apply a restoring force toward the upper side while the control rod 50 is lowered.

The operation lever 70 is installed in a structure in which a substantially half-moon-shaped body performing a handle function is rotatable on the front side of the main body 10, and a rotating plate coupling portion 72 is disposed on the rear side of the body part 10 ) Is installed and configured to pass through the through hole 20.

The rotation plate coupling part 72 on the rear side of the operation lever 70 is configured to form a cylindrical shape in the front portion and a square plate shape in order to interlock with the rotation plate 80.

The rotating plate 80 has a substantially disk shape, and an interlocking groove 86 is formed in the center thereof, and an open groove 82 is formed at the lower end of the outer circumferential surface of the disk shape, and 90° left and right from the open groove 82. Each of the points is configured to be formed with a locking groove (84).

The interlocking groove 86 of the rotating plate 80 is formed to have a circular shape in the front part and a square shape in the rear part, so that the rotating groove in a state that is firmly engaged with the rotating plate coupling part 72 of the operation lever 70 ( 86) through the screw that is fastened to the rotating plate coupling portion 72 is configured to be firmly coupled.

In addition, the rotating plate 80 is configured to have a height corresponding to the discharge port 26 of the main body 10 by forming an upper portion of the rear side to protrude a certain height through the stepped 88, and the protruding The locking member 89 is installed through a portion.

The locking member 89 has an approximately "⊂" shape, and is fixedly coupled through a screw that is fastened to the rotating plate 80 through the coupling hole 89a while being positioned on the protruding surface of the rotating plate 80 Thus, when the rotating plate 80 is rotated according to the operation of the operation lever 70, it is configured to be discharged to the outside through the discharge port 26 of the main body 10.

The locking member 89 may be mounted on the protruding surface of the rotating plate 80 by changing left and right to form a "⊂" shape or a "⊃" shape according to the usage environment of the corresponding locking device, and accordingly, the locking member 89 may be mounted on the protruding surface of the rotating plate 80. The discharge is made through the discharge port 26 on one side or the other side of the main body 10.

Next, the operation of the present invention made as described above will be described with reference to FIG.

The mechanical locking device for a window according to the present invention, as shown in Figs. 4 and 5, is installed at a portion where a pair of windows 200 that are opened and closed in a sliding door manner overlap each other, and the main body part on one side window In addition to the installation of 10, a locking bracket 100 is installed and provided on the other side of the window so as to be adjacent to the main body 10.

In accordance with the environment of the window 100 in which the mechanical locking device for the window is installed, the locking member 89 embedded in the main body 10 is mounted on the rotating plate 80 to form an approximately "⊂" shape or a "⊃" shape. Can be provided (see Figs. 6A and 6B).

Meanwhile, in order to maintain the locked state of the window through the mechanical locking device for the window, the number of the three dialing 60 is arranged according to the set password while the user selectively rotates the plurality of dialing 60. Make it possible.

Accordingly, the control rod 50 is converted to a state in which it can be lowered, and at this time, as the user applies a rotational force while holding the operation lever 70, the rotation plate 80 is also interlocked to rotate by a certain angle. The upper end of the control rod 50 is naturally separated from the open groove 82 of the rotating plate 80 along the outer circumferential surface and descends by a predetermined distance.

In addition, as shown in Figs. 6A and 6B, when the rotating plate 80 is interlocked according to the rotation operation of the operation lever 70, the locking member 89 installed on the rotating plate 80 is also rotated and its shape From this roughly "⊂" shape or "⊃" shape, it moves to form approximately "∩".

At this time, the locking member 89 is inserted into the locking member insertion hole 110 of the locking bracket 100 after a part of the body is discharged to the outside through the discharge port 26 of the main body 10 It will be.

In the rotational state of the operation lever 70 and the rotating plate 80 by approximately 90°, the locking member 89 forms an approximately "∩" and the upper end of the groove is the discharge port 26 of the main body 10 A state in contact with the lower end is achieved, and at this time, the control rod 50 rises by a certain height by the restoring force of the return spring 54, and the upper end thereof is intercepted by the locking groove 84 of the rotating plate 80.

On the other hand, in a state where the upper end of the operating rod 50 is inserted into the opening groove 82 or the locking groove 84 of the rotating plate 80, the dialing 60 is operated so that an arbitrary number other than the password is displayed on the front side. As the arrangement is made, the operating rod 50 maintains a state in which it is impossible to move up and down, and accordingly, even if an external force is applied to the operation lever 70, the operation lever 70 and the rotating plate 80 are It is possible to prevent arbitrary manipulation by others while maintaining a state in which rotation is impossible.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and in the technical field to which the present invention pertains within the scope not departing from the gist of the present invention claimed in the claims. Various modifications and modifications are possible by those of ordinary skill in the art, as well as these modifications and modifications should not be individually understood from the technical spirit or prospect of the present invention.
