Description

Locking device of window

The present invention relates to a locking device for a window, and more particularly, to a locking device configured to easily lock or unlock a window.

In general, a window is an opening door installed at one side wall of a building for dimming or ventilation purposes. In the above window, a window is generally made of glass or transparent synthetic resin for a light-transmitting effect, and a durable window frame is provided on the outside of the window. It is configured by installing it.

The role of the window frame not only protects the window but also serves as a guide when opening and closing the window. The glass frame or transparent synthetic resin is provided to transmit light or the user may selectively open and close the window to ventilate the room. The window is divided into a sliding door or a sliding door according to the manner of opening and closing.

In addition, the window frame is generally composed of wood or aluminum, but a variety of materials may be used for the interior or special purpose.

To date, the role of such windows tends to be heavily focused on external interiors in addition to their original purpose, and the development of related accessories is actively being made to add convenience.

One of the accessories for adding the convenience is a locking device, which is also diversified and trending to make life more convenient.

Then, a brief look at the conventional window locking device is as follows.

In general, in the sliding window (1), the locking device is inserted into the locking frame (3) directly below the inner window frame (2a) where the window frame (2) intersects to facilitate opening and closing of the window (1). As installed, it is configured to lock or unlock the window 1 according to the user's operation.

One end of the locking key 3 is formed with a screw 5 and the other end is formed with a handle 6, and a screw insertion groove 4 having a predetermined depth is formed at one side opposite to the screw 5. If necessary, if you hold the handle 6 of the locking key 3 and turn in one direction, the locking key 3 is rotated and the screw 5 at the end is gradually inserted into the screw insertion groove 4.

At this time, when the locking key 3 is rotated to a predetermined depth and fastened to the screw insertion groove 4, the inner and outer window frames 2a and 2b are screwed together to be fixed to each other so that they are restrained from each other. In this case, the window 1 is not opened even if the window 1 is pushed or pulled.

On the other hand, since the hinge portion 7 is formed at the stop of the locking key 3, the locking key 3 protruding when the lock is released is folded to one side to prevent the user's clothes from being caught and torn.

In addition, when the lock state of the window 1 is to be released, the screw 5 of the locking key 3 is released from the screw insertion groove 4 when the handle 6 is released by turning in the opposite direction as described above. The locked state of the window 1 is released.

However, when locking or unlocking the window by the above method, the handle of the locking key must be fastened or loosened by hand, so that it is cumbersome and difficult for the user who performs such an operation, and when a certain period of time passes. Due to the repeated screwing of the lock key, the screw and the screw groove are worn out to each other, so that the fastening is loosened.

In addition, this is also pointed out as an unpleasant metallic sound is emitted by the friction of the metal with each other when the screw is fastened as described above.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a locking device for a simple operation and easy installation according to the locking and unlocking.

Hereinafter, the configuration of the apparatus according to the present invention will be described in detail according to an embodiment.

The cylindrical housing 10 is inserted and installed in the inner window frame 2a among the portions where the window 1 is completely closed, and the housing is repeatedly formed with guide grooves 11 having a predetermined depth along the inner circumferential surface. An annular cap 14 is formed at the front opening of the housing 10 so that one end is inserted into or protrudes into the housing 10 according to a user's pressing operation, and the other end is repeatedly provided with a conical feed tooth 15. The formed operation piece 13 is inserted.

In addition, as the first guide protrusions 16 are formed at the upper end of the transfer tooth 15, the guide grooves 11 are guided within a predetermined range and seated to reciprocate.

Meanwhile, a second guide protrusion 19 protrudes from the distal end of the rotation shaft 17 in a state where one end of the rotation shaft 17 is inserted into the feed tooth 15 of the operation piece 13. The second guide protrusion 19 has a shape arranged in plural at regular intervals along the outer circumferential surface of the pivot shaft 17.

Here, the inclined surfaces 18 are formed in one direction so that the end of the second guide protrusion 19 and the both ends of the inlet end of the guide groove 11 engaged with the second guide protrusion are in sliding engagement with each other.

In addition, as the pivot shaft 17 is fixed to the latch 21 through the latching jaw 12 formed at the rear of the housing 10, the latch 21 is fixed to the inside of the housing 10 by a predetermined depth or more. It is restricted from being inserted.

The elastic spring 20 is provided on the pivot shaft 17 between the second guide protrusion 19 and the latching jaw 12 to add an elastic force.

On the other hand, a latch insertion hole 22 is formed in the outer window frame 2b so as to accommodate the latch 21 protruding from the housing 10 at a portion facing the latch 21.

Now with reference to the accompanying Figure 5 with respect to the operation of the device of the present invention will be described in detail.

First, in a state in which the window 1 is completely closed to both sides, the user operates the locking device installed at the intersection of the window 1 to lock or unlock the window 1, which is installed in the inner window frame 2a. The cap 14 is inserted into the housing 10 as the user presses the cap 14 protruding toward the room.

At the same time, as the operation piece 13 integrated with the cap 14 is pushed to the rear of the housing, a force is transmitted to the rear feed tooth 15, and the transfer tooth 15 is the second guide protrusion 19. Since it is engaged with the state and compresses the elastic spring 20 installed in the rear to push the pivot shaft 17 to the rear.

Here, the pivot shaft 17 is fixed integrally with the latch 21, so that the latch 21 protrudes out of the housing 10, and at this time, the protruding latch 21 is outside. The latch insertion hole 22 of the side window frame 2 is inserted into the latch insertion hole 22 as it faces each other.

Meanwhile, as the cap 14 is pressed and inserted, the second guide protrusion 19 pushed out by the guide groove 11 is out of the area of the guide groove 11 at any moment, and at this time, the second guide Since the projections 19 are not supported laterally by the guide grooves 11, they slide up to the valleys of the feed teeth 15. At this time, the pivot shaft 17 is rotated by a certain amount to one side by the sliding motion. .

On the other hand, when the user releases the hand holding the cap 14, the force holding the elastic spring 20 is lost, so again due to the repulsive force of the elastic spring 20, the rotating shaft 17 and the operation piece 13 This is pushed in the reverse direction, at this time, the transfer tooth 15 is the state that was supporting the second guide projection 19 by pushing the rear, so that the second guide projection ( It is understood that 19) also moves forward.

However, at this time, since the rotation shaft 17 is rotated by a predetermined amount, the second guide protrusion 19 is not inserted into the guide groove 11 correctly and slides along the inclined surface 18 of the guide groove, so that the guide groove ( 11) over the top end.

Therefore, since the latch 21 is fixed to the pivot shaft 17, the latch is supported while being inserted into the latch insertion hole 22 so that the window 1 is locked.

In addition, in order to unlock the window 1, as the user presses the cap 14 once more, the series of processes are repeatedly performed, and the guide groove 11 has a shape of the second guide protrusion 19. ) Has a configuration in which the depth is repeatedly differently inserted so that the second guide protrusion 19 slides on the inclined surface 18 of the guide groove 11 and is inserted into the guide groove 11. The original state is again as shown in FIG. 5A.

Therefore, the user can easily lock and unlock the window 1 by simply pressing the cap 14 repeatedly as the latch 21 is repeatedly inserted into and removed from the housing and inserted into the latch insertion hole 22. .

The lock device of the present invention is easy to operate and install according to the locking and unlocking of the window during use, and it is very effective because the locking state of the window can be checked from a distance.
