Description

Sliding door window automatic movement the system which locks}

According to the present invention, in a sliding dongle including a sliding window, a door (window) is attached to a wall (window mounting frame) (acting to close the window) to induce breakage of two symmetrical hooks and external intrusion locks. The present invention relates to an automatic locking device for a sliding window that automatically locks a window provided with a security fixing plate that blocks foreign substances (various forced release tools).

In the window lock device, there are various techniques for the button-type or hook-type window lock. Particularly, in the case of the automatic locking device for a button-type window of the Republic of Korea registered practical 20-0409479, the locking part (the latch part of the present invention) is fixed to the window, built in the hook case and hook case sealed by the cover, and protrudes up and down Pins are coupled to the hook case and cover, and the hooks and hooks with U-shaped grooves formed in the strike are coupled to the pins so that the unlocking state is maintained, and both ends of the coil springs are hooked to the hooks and the hook case. When the protruding pin is engaged with the hook case and rotated, when the hook is in the locked state, the lever and the lever, which is embedded in the groove formed in the hook, and placed in the guide groove formed in the hook when the hook is in the unlocked state, are always elastic Restoration spring installed between the pressure plate and hook case integrally formed on the lower side of the lever to support and the operation hole formed with a cover to press the pressure plate, the button portion window The elastic spring of the restoring spring and the restoring spring is built in the stand and the stand is fixed, and the pressure pin is pressed to press the pressure plate through the operation hole and the configuration includes a snap ring coupled to the pressure pin exposed to the rear of the stand. It has the effect of keeping the window locked when the window is closed.

Therefore, in the present invention, in order to overcome the single locking function, which is a problem of the above technology, as well as the above technically effective technology, and to allow the hook-shaped locking plate to be safely seated on the catch portion, the locking is induced only in one direction. In order to overcome this problem, in order to be able to lock in both directions, and to protect the seat plate from being detached from the outside, in order to insert the fixing plate, by providing a locking device that can be rotated and moved, even in the window lock device It has a more secure window lock function.

The current structure of window locks is that most window locks are only locked automatically, but the security is not considered deeply. The reason for this is that since most theft cases use a method of breaking into the window and exiting the front door, the robustness of the window lock is required.

The present invention to overcome the above problems,

Due to the sliding of the window frame, that is, the closing of the window,

As the locking plate operating part rotates in the locking plate rotating part of the fixing plate while meeting the catching plate operating part base of the catch part, it is pushed into the catching plate inserting part of the catch part like the fixing plate inserting part of the locking plate and the fixing plate based on the locking plate operating part. The blocking plate located on the rear part provides a self-locking device for a sliding window, which is characterized in that the seesaw-type blocking plate blocks the back of the fixing plate behind the fixing plate separated by the blocking plate spring to lock the window.

In addition, in order to open the locked window, provided with a rotating joint of a certain angle to the handle portion that can be rotated in the handle case part, and Milpin Laura provided on the rotating joint pushes the moving plate,

Pressing the centering presser board (circular) of the center of the core at the position of the horizontal deviating prevention plate of the moving plate, the presser of the presser board of the presser type presses the presser plate of the blocking plate of the latching part while the keying presser board of the wedge-shaped presses the centering presser board. Due to this, while the blocking plate is lifted based on the blocking plate seesaw, the fixing plate is pushed back by the fixing plate spring, and the locking plate and the fixing plate inserted in the catch portion are separated to release the automatic locking. It is an object to provide an automatic lock for sliding windows.

As described above, the disadvantage of the sliding door including the current sliding window is that most locking devices rotate the shape of the hook to catch or use a system that is inserted into the catch to prevent the door from opening again. have. However, these hooks (lock plate in the present name) type locks are vulnerable to preventing external intrusion. This destroys security by developing doors by removing or rotating the tip of the hook with a large screwdriver or other tools.

However, the present invention uses the two locking plates in the same space to catch the shaking of the door and to secure the tightness of the locking device, and at the same time to prevent the intrusion of the outside, the fixing plate for protecting the hook-shaped locking plate again It is reinserted to protect the stopping plate from the outside.

This is because the three locking devices revolve in the same space, which is the main action of the door, which occurs mainly in the hook-type locking device. By opening the fixing plate is inserted into the door and the door, or the space between the door and the door frame, it is possible to provide a secure locking device.

In addition, in the operation of the sliding door including the window, while most of the handle form is a lever-shaped protrusion, the structure of the present invention has a foldable structure by embedding, so that a large portion of the transparent glass occupies a large portion. In order to block sunlight from a window or sliding door, there is no interference in the handle when installing curtains or blinds, and the function of opening the window only by lifting the buried handle and only pushing the window (sliding door) to the window mounting frame By locking the window, anyone can easily lock and open the window (sliding door).

In addition, the handle case part 50 that controls the opening is installed on the inner surface or the outer surface of the window frame 200. At this time, in order to operate the handle case part 50 and the latch part 30, a core 60 formed in the handle case part 50 is formed by drilling a hole in a portion of the window frame 200. Install to connect Due to this, the window installation frame 100 and the window frame 200 in the sliding door window while maintaining the relationship with each other to perform the locking and opening function of the door.

Reference is made to FIG. 2 to describe the configuration of the present invention in more detail.

2 is a perspective view showing the structure of the latch installed in the window handle portion and the window frame of the representative road of the present invention.

The automatic locking device for a sliding window of the present invention is divided into three types of configuration, the catch part 20 serving as a strike in the general door lock locking device, the window installation of the window installation frame 100 corresponding to the door frame The fixing bolt is inserted into and fixed to the catch installation bolt hole 23 of the catch 20 on the surface of the frame moving rail 110.

At this time, the catch plate inserting portion 21, the catch plate operating portion pedestal 22 of the catch portion 20 is configured to face the latch portion 30.

The latch portion 30 installed on the window frame rail inserting portion 210 is such that the center portion inserting portion 31a is visible (located in an operable range) in a hole previously drilled in the window frame 200, and the latch portion (30) of the window frame installation fixing bolt hole (35a) by inserting a fixing bolt was configured to fix the latch portion 30 to the window frame rail inserting portion (210).

The latch part 30 has a fixing plate 33 positioned on the latch case part 35, and the fixing plate 33 has a fixing plate detachment preventing part 33c to prevent the fixing plate 33 from being separated from the latch case part 35. The fixing plate release preventing part 33c has a fixing plate spring 33d so that the fixing plate 33 is always pushed back in the latch case part 35. The stationary plate spring 33d provided in the stationary plate detachment preventing unit 33c is always such that the stationary plate 33 is positioned backward in the latch case part 35.
In addition, the fixing plate departure preventing portion 33c is configured to protrude at the ends of both wings of the fixing plate 33, which is because the fixing plate spring 33d always pushes the fixing plate 33 inwards, The fixing plate detachment prevention part 33c is provided so that it may be located inside the 30. In addition, even if the catching plate 32 is rotated to catch the catch portion 20, the fixing plate detachment preventing portion 33c is provided in the closed portion installed on both sides of the open surface for the operation of the catching plate 32 of the latch portion 30 33) prevents the window frame 200 from being separated from the window installation frame 100 by preventing the departure of the window.

The fixing plate 33 is provided with a locking plate rotating part 33b so that the locking plate 32 is located, and leveling the locking plate 32 to prevent the locking plate 32 from being forcibly returned by intrusion from the outside. It has a fixed plate insert 33a for.

The fixed plate 33 configured as described above is always positioned behind the inside of the latch case part 35, and then the window frame 200 is installed on the window mounting frame moving rail 110 of the window mounting frame 100 in the direction of the catch part 20. When it is pushed to the engaging plate operating portion 32b of the latching portion 30, the catching plate 32 of the latching portion 30, the catching plate operating portion of the catching plate 32 It starts to rotate with reference to 32b.

At this time, the locking plate operating portion 32b of the locking plate 32 also rotates around the locking plate installation hole 32a, but the center of rotation is the locking plate operating portion 32b as a reference point. While rotating, the fixing plate 33 is also moved toward the catch portion 20. Eventually, while the window frame 200 moves, the latch unit 30 meets the catch unit 20, and the two stopping plates 32 operate based on the stopping plate operating unit 32b, while the stopping plate 32 and the fixing plate ( The fixing plate insert 33a of the 33 is pushed forward, which is inserted into the catching plate inserting part 21 of the catching part 20 while catching the back of the catching plate operating part pedestal 22 of the catching part 20. Part of the catch 20 is locked by the locking portion 32c.

In addition, in order to prevent the locking plate 32 and the fixed plate inserting portion 33a inserted into the catch portion 20 from being pushed back by the fixing plate spring 33d provided in the fixing plate release preventing portion 33c. The blocking plate 34 prevents the empty space generated by vertical movement and rotation of the locking plate 32 and the fixed plate insertion unit 33a operated as described above.

Before the operation as described above, the position of the blocking plate 34 is positioned on the rear portion of the fixing plate 33. However, the locking plate 32 is rotated based on the locking plate operating portion 32b of the locking plate 32 and the fixed plate 33 is linearly moved by the rotational movement force toward the catch 20. The blocking plate 34 is located behind the fixing plate 33.

In such a state, the space where the locking plate 32 and the fixing plate 33 are separated is moved by the pressure always provided toward the fixing plate 33, that is, the blocking plate spring 34a provided in the blocking plate 34.

However, in order to open the door, when the pressing plate 34c of the blocking plate 34 is pressed while the center portion 60 descends from the handle, that is, the handle case part 50, the pressing plate 34c is blocked. The rear part of the blocking plate 34 is lifted around the plate seesaw support 35b and the blocking plate seesaw stand 34d, and the operation is reversed by the fixing plate spring 33d of the fixing plate 33. Since the space of the plate 34 is filled, the locking plate 32 and the fixing plate 33, which are locking devices inserted into the catch part 20, are separated, thereby opening the door.

At this time, although not shown and not shown in the drawings, after the catching plate 32 and the catching plate are gathered, a magnet is provided on some surfaces to prevent sagging or returning, thereby preventing the two catching plates 32 from being separated.

The latch case part 35 is disposed on the latch case part 35 configured as described above, and the fixing bolt is inserted into the cover fixing bolt hole 31b of the latch cover part 31 to be coupled to the latch case part 35. It was.

It is to rotate the rotary joint 44 and the handle portion 40 of a predetermined angle.

This will be described again with reference to FIG. 3, and thus the handle part 40 is lifted in the handle case part 50 to move the moving plate 53 inside the handle case part 50. That is, the rotary joint 44 fixed to the handle part 40 has a function of causing the moving plate 53 to move horizontally when the handle part 40 makes vertical movement.

Inside the handle case 50, a movable plate 53 for performing horizontal movement by the Milpin Laura 45 is positioned, and a movable plate support part 51 for preventing the positional deviation of the movable plate is installed. For the purpose of illustration, the movable plate support part 51 is a component fixed to the original handle case part 50, but has been separately separated for detailed description.

In addition, a moving plate spring 54 is provided on the moving plate spring support part 52 attached to a part surface of the handle case part 50 to return the moving plate 53 to continuously push the moving plate 53. Due to this, even if the handle part 40 is opened, it is returned to the handle case part 50 again.

The moving plate 53 allows the center portion 60 to move up and down while moving horizontally. The moving plate 53 has a center structure of the horizontal structure in order to keep the structure from pressing the center portion 60. When the release prevention plate 53a is provided, when the movable plate 53 is horizontally moved to press the center portion 60 next to it, the wedge-shaped press plate 53b of the wedge shape reverses its shape. The center portion 60 is pushed down while pushing the centered nurum chain substrate 61 in a diagonal line.

Due to this, the center portion 60 descends to press the pressing plate 34c of the latch portion 30 described above, and again performs the opening function of the door by the blocking plate spring 34a and then returns to return.

In addition, since the case cover 55 is positioned to protect the components inside the handle case 50, the components are protected or operated smoothly.

In order to explain the above functions in more detail, reference is made to FIG. 3.

The handle portion 40 only needs to be operated vertically to open the door. 2, the rotary joint 44 installed in the rotary joint fixing part 42 on the handle 40 has a predetermined angle to move the Milpin Laura 45 due to the handle 40 being lifted. do. Then, the moving plate 53 is horizontally moved by the force of the handle portion 40 that is vertically lifted.

As shown in the right side of FIG. 3, in the case of the handle portion 40A in the non-operating state, the center of the horizontal plate of the movable plate 53 is located because the position of the movable plate 53 is close to the direction of the Milpin roller 45. Due to the location of the center portion 60 in the lower portion of the separation prevention plate 53a, the center portion 60 is in a raised state. The state in which the center portion 60 is raised is because the pressing plate 34c of the latch portion 30 is lifted by the blocking plate spring 34a.

As shown in the left side of FIG. 3, when the Milpin Laura 45 pushes the movable plate 53 due to the movement of the handle part 40, the centered press board 53b having a wedge shape in the position direction of the center part 60 is provided. Therefore, the center nucleus pressurized chain substrate 61 of the center portion 60 is pressed, and the center portion 60 is vertically moved due to the diagonal force. As a result, the center portion 60, which is energized by the center portion Nurum chain board 61, opens the blocking plate 34 of the latch portion 30, thereby opening the door.

In order to explain the structure of the moving plate 53, the moving plate structure of one surface is omitted in the circular reference diagram. This may be regarded as omitting that the two cradles, which may have two moving plate springs 54 on both sides, are coupled to the moving plate 53.
