Abstract

The present invention relates to a window locking apparatus. Window locking apparatuses are doubly installed in two places such that one side can be locked in accordance with locking of the other side. When a timing belt and a pulley are installed at the inside of a window so as to simultaneously move rotary shafts of the two locking apparatuses, a child with a short height is able to conveniently lock or open the window. In addition, the child is not required to use an additional foot support to go up and rotate a latch, thereby preventing the child from getting accidents.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a locking device for a window, and more particularly, to a locking device for installing two locking devices in two places.

The windows are installed on the walls of the building to receive air or sunlight from inside the building.

In general, the walls of the building and the window frame are fixed and a pair of windows supporting the glass are mounted to slide sideways along the rails provided at the bottom of the window frame.

When a pair of windows is moved in one direction, the windows are opened, and when they are moved in both directions, the windows can be closed.

These windows are equipped with locks to prevent the windows from opening by preventing the windows from sliding. For example, one window has a lock ring and the other window has a lever with a latch.

When you close the window and rotate the pendant in one direction to lock it into the lock ring, you can lock it by blocking the sliding of the window. In contrast, if you rotate the pendant in the opposite direction and release the latch from the lock ring, The window will open.

Most windows, however, have a lock to lock the window in the middle of the window, so a child with a small height needs to stand on the pedestal using a separate pedestal to lock or unlock the window, There is a possibility of being hit.

Therefore, it is necessary to develop a window locking device which can be used conveniently for children with a small height.

It is an object of the present invention to provide a window locking device capable of easily opening and closing a child with a small height without using a chair or a tool, utilizing a conventional window frame, and preventing a safety accident.

The above object is achieved by providing two lock rings on one window frame of a pair of window frames; Two latches on the other window frame, which are engaged and disengaged by rotation on the two locking rings; Two pivot shafts connected to the inside of the window frame so that the two pawls can simultaneously move the lock position and the unlock position; A pulley coupled to the rotating shaft and including concave and convex portions for preventing a timing belt from slipping when transmitting a rotational force; And can be achieved by a timing belt including concavities and convexities so as to be able to transmit the rotation in conjunction with the two pulleys.

According to an aspect of the present invention, the pulley includes a timing belt and a pulley fastened in a direction in which a timing belt moves in order to prevent a timing belt from falling out during operation. Unevenness can be provided on the left and right sides of the part. Also, the mounting positions of the two locking hooks and the latches are respectively located at 25% and 75% of the total length in the vertical direction of the mounting state of the window.

The present invention improves the locking structure of a window, so that a child with a small height can be easily opened and closed without a chair or a tool, and a safety accident can be prevented. In addition, you can make the most of existing window frames and locks.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The present invention is not limited to these embodiments.

FIG. 1 is a perspective view of a window to which a double window locking device of the present invention is applied, and FIG. 2 is a perspective view of a pulley including a rotating shaft and an unevenness for transmitting rotation of a window locking device and a window locking device. 3 is a perspective view showing a state in which a timing belt including concavo-convex is fastened in Fig. 2; Fig.

A window frame is fixed to a wall of a general building, and a pair of windows 101 and 102 shown in FIG. 1 are mounted on the window frame. The glasses 103 and 104 are fixed to the windows. When the pair of windows 101 and 102 are moved in one direction, the windows are opened and the windows can be closed by moving them in both the left and right directions. In general, locks are installed on the windows. For example, in one of the pair of windows, a lever (201) having a lock ring (203) and a latch (201) on the other side is installed in the middle part of the window.

In FIG. 1, although the locks 203 and 204 of the window locking device according to the embodiment of the present invention and the levers 201 and 202 formed with the latches are shown, the rotary shaft, the timing belt, and the pulleys are not exposed. This is because these parts are inside the window of the window 101.

In FIG. 2, a lever 201 having a latch, a latch 213, a rotating shaft 205, and a pulley 206 including concavities and convexities are formed.

In FIG. 3, the timing belt 210 including the unevenness is located outside the pulley 206 including the unevenness shown in FIG.

The position of the locking device shown in FIG. 3 is located at a position spaced apart from the floor by about 75% from the bottom in the vertical direction of the mounting state of the window as shown in FIG. 1, and the other pair of levers 202 and the locking hooks 204 It is located at about 25% apart.

A pulley including the concave and convex portions of these two locking devices is fastened by a timing belt 210 including concave and convex portions.

4 shows a configuration in which two locking devices are connected using a timing belt.

When the lever 201 is rotated in one direction after the window is moved in both left and right directions to lock the window, the pulley including the rotation axis and the unevenness rotates together.

The pulleys including the concavo-convexes include the same tooth profile as that of the timing belt, so that the rotational force of the pulley can be converted into the tensile force of the timing belt.

The rotational force of the pulley is transmitted by the tension force of the timing belt and is transmitted by the rotational force of the other pulley 212 to rotate the other lever 202 through the rotational shaft. Also, when the other lever 202 is rotated by changing the order, the lever 201 can be rotated in the same manner on the same principle.

FIG. 4 shows a state in which the locking device is open, and FIG. 5 shows a state in which the locking device is locked.

If the rotation of the locking device is transmitted by using the timing belt, there is no loss due to the friction between the pulley and the timing belt.
