KR200212204Y1 - A safe window lock from robbery - Google Patents

Abstract

The present invention relates to a lock of a sliding window, and the conventional window lock can be locked only when the window is completely closed, but the present invention is not only closed but also locks the window at any position in the middle according to the needs of the user. It is a device that keeps the windows open for ventilation in the summer and is safe from intrusion when going out.

To this end, a lock gear to be engaged with a window rail or a groove formed in the window is coupled to the inside of the lock case, and a lock for controlling the rotation of the lock gear is coupled according to the position of the lock state conversion knob.

According to the above configuration, the window can be completely locked or closed depending on the position of the lock state shift knob, but can not be opened or opened freely, and the window can be opened when the position of the lock state shift knob is only closed. Since you can't open it anymore, if you leave the door a little open for ventilation and just go out, it will be impossible to intrude.

Description

Anti-theft sliding door lock automatic locking device {A safe window lock from robbery}

We wanted to make it possible to lock even when the window is open. There are many cases in which we open the windows to purify muddy indoor air or suspect gas leaks, and many of us suffer from theft of being stolen because we forget to lock them because of carelessness. Even if the door is left open for ventilation to prevent it, the device is locked.

There are many types of locks on the windows, but all of them can be locked only when they are completely closed. These windows must be checked for locking. This invention attempted to prevent the misfortune of losing valuable property by one carelessness by automatically locking the door without such troublesomeness.

Figure 3 is a view of the catch in the locking device, with a scale of 1: 5. 4 shows the operation of the locking device, the state of ① is a mode in which the gear in the locking device can freely rotate, the state of ② is a mode that can be rotated in one direction, and the state of ③ is a mode in which bidirectional rotation is impossible. .

(1) locking gears (2) locks (3) window rails (4) cases (5) locking handles (6) lock tops (7) lock bottoms (8) locking jaws

In order to solve the above problems, the present invention combines the lock gear 1 to one side of the case 4 to be rotatable and controls the rotation of the lock gear according to the position of the lock state conversion knob 5 ( 2) to the side of the lock gear.The lock state change knob allows the position of the lock to be changed along the hole of the arc shaped on the face of the case facing upward when the lock is engaged to the window. Engage with the internal clamp.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a drawing of a locking device in a third angle method, as shown in FIG. It is coupled to the rotatable, and the lock to control the rotation of the lock gear according to the position of the locking state conversion knob is coupled to the lock gear side. The locking state change knob allows the position to be changed so as to engage with the internal fastener from the outside of the case through an arc-shaped hole. FIG. 3 is an exploded perspective view of the fastener, which is provided between the upper plate 6 and the lower plate 7. It is coupled with the spring to adjust the angle of the two plates, the lower plate has a connecting portion connected to the locking jaw (8) and the lock state conversion knob in contact with the lock gear. If the teeth of the lock gear push the bottom plate of the lock when the lock gear is rotated, the four edges of the end of the side of the face formed with a hole for the coupling pin to join the top plate and the bottom plate to make the angle change of the top plate and the bottom plate on the contact side Figure 4 is a view showing the state of the clamp and the lock gear according to the position of the locking state conversion knob, the state of ① is the bottom of the clamp when the lock gear rotates. In this state, the lock has no influence on the rotation of the lock gear, so that the lock can rotate freely. The state of ② is the elasticity of the spring coupled between the upper and lower plates of the lock and the two edges. Because the angle of the lock gear rotates counterclockwise, Repeats is considered changed in the direction tangent to the circle constituting when the lock gear rotates to be restored by the resiliency of the spring in the lock catch. When the lock gear rotates in the clockwise direction, since the other edge of the end of the surface where the coupling pin for joining the upper plate and the lower plate is formed is not smoothed, the teeth of the gear are caught by the catching jaw of the lower plate of the clamp. The state of ③ cannot be rotated because of the same action as in ② when the lock gear is rotated in the clockwise direction, and the lock that is caused by the change of position of the lock conversion knob when rotated counterclockwise. The change of the angle of the gear is so large that the teeth of the lock gear push the lower plate of the lock so that the teeth of the lock gear cannot rotate beyond the lock even if the angle of the lock plate is completely changed. In this case, a groove that is engaged with the lock gear is formed in the window rail. The operation of the locking device according to the operation of the lock gear and the lock according to the position of the lock state handle described below is as follows. First, if the lock state handle is placed in the fully locked ③ position, the lock gear cannot rotate and the lock gear cannot be rotated. And the window rail grooves (3) are interlocked with each other, so that the window cannot be opened or closed. Secondly, if the position of the locked handle is half-locked ②, the lock gear can rotate only in one direction. Thirdly, if the lock position knob is in the open ① position, the lock gear rotates freely so that the window can be opened or closed freely. The groove to be engaged with is formed in the window rail, and when the locking device is attached to the window frame, the groove is formed in the window.

If you open the window to clean indoor air or suspect a gas leak, you can open the window with confidence because it is an excellent security device.

Claims (1)

In the configuration of the locking device for theft prevention, the lock gear 1 is rotatably coupled to one side of the case 4, and the lock state change knob is formed along an arc-shaped hole formed on the upper side of the case. Locking state by engaging the lock (2) to the side of the lock gear to be able to change its position is coupled to the internal lock on the outside of the case and controls the rotation of the lock gear according to the position of the lock state conversion knob (5) Due to the action of the lock gear (1), the groove (3), and the lock (2) according to the position of the conversion knob (4), three modes can be opened, i. A lock for a sliding window, characterized in that it has a ② mode and a ③ mode that is completely locked.
