Description

Anti-opening device of sliding window for crime prevention

The present invention relates to an opening preventing device of a sliding window for crime prevention, and more particularly, to an opening preventing device of a sliding window that can be opened only from the inside so that outsiders can not intrude through the window.

Openable windows, unlike doors for entry and exit, are constructed for ventilation and light in the room. However, the window is used as a means of passage for a person who wants to invade for theft or injury, and safety measures are required. Although most windows have locks that allow them to be locked and unlocked only from the inside, incidents of theft or injury often occur that allow outsiders to easily invade by forgetting or neglecting to lock the windows. Moreover, since the locking device installed in the conventional window is effective only when the window is completely closed, it is practically useless, such as safety cannot be guaranteed in the open state for ventilation.

On the other hand, a variety of locking devices such as hooks, clasps, and levers have been devised for windows, but most of them are structurally weak and therefore inferior in safety and inconvenient to use.

It is an object of the present invention to provide a sliding door opening preventing device for crime prevention that can be opened only from the inside to prevent outsiders from invading through the sliding window.

It is also an object of the present invention to provide a sliding door opening prevention device for crime prevention that can not be opened from the outside without the operation of locking the windows one by one for the convenience of the user with the safety to prevent the intrusion of outside windows.

The rack 10 is a gear 12 formed in a belt-shaped body 11 having a constant width at regular intervals, and is prepared in accordance with the horizontal length of the window 2 'or the minimum required length. For the installation thereof, the window 2 'is provided with a groove in the longitudinal direction of the upper frame part (not shown) of the window frame 4' to a depth considering the height of the tip of the rack 10, and thus a long rack mounting groove 6 in the longitudinal direction thereof. After forming the '), the prepared rack 10 is fixed by driving the screw 13 in the rack installation groove (6').

As shown in FIG. 2, the pinion assembly 20 has an opening 21a formed on the front surface thereof, the fixing portion 21b on both sides of the opening 21a, the outlet 21c on the rear surface, and the inner surface of the opening 21a side. A housing 21 having a locking portion 21d on the pin 21, and the pinion 22 to be engaged with the rack 10 in the housing 21, and a stopper 24 and a spring 26 for controlling one-way rotation thereof. ), And the pull string 27 for releasing the one-way rotation control function is extended out through the outlet 21c of the housing 21. In the housing 21, the pinion 22 is rotatably installed on the shaft 23 so that a part of the gear 22a protrudes slightly out of the opening 21a, and the stopper 24 is attached to the shaft (of the pinion 22). The hinge portion 24a of the one end is inserted into the pin 25 installed in parallel with 23, and the free end 24b is supported to rotate while being engaged with the gear 22a of the pinion 22, and the freedom thereof. A spring 26 is interposed between the stopper 24 and the inner surface of the housing 21 so that the stage 24b is pressed toward the engaging portion 21d of the housing 21. And the pulling line 27 is tied to the stopper 24, it passes through the spring 26, and it draws out to the outlet 21c of the housing 21.

In installing such a pinion assembly 20 in the window 2, first, the housing 21 described above on the outer surface (not shown) of the upper frame part (not shown) constituting the window frame 4 of the window 2. The pinion installation groove 6 is excavated to a size that can accommodate the body portion, and also a hole 7 penetrating into the front of the window frame 4 in the pinion installation groove 6. Next, the body 21 of the pinion assembly 20 is embedded in the pinion installation groove 5, and a screw 28 is fixed to the fixing portion 21b, whereby the pull string 27 is a hole ( 7) to be withdrawn to the indoor side.

On the inner side of the window frame 4 is provided with a guide (30) for guiding to pull the pull string 27 drawn out through the hole (7) without downwards, the guide 30 is the window frame (4) It consists of a bracket (31) that can be fixed to the inner surface with a screw (33) and a round bar (32) which is supported in a horizontal position on the bracket (31) to hang the pull string (27).

On the other hand, at the end of the pull string 27, the hook 40 is suspended, and the hanger pin 41 which allows the hook 40 to be hung in a pulled state is driven at a suitable height of the frame part of the window frame 4.

Referring to Figures 4 to 6 the operation of the opening prevention device of the sliding window for crime prevention according to the present invention carried out as described above are as follows.

First, FIG. 4 shows an operation in which the inner window 2 is closed with respect to the outer window 2 ′. As shown in the drawing, when the inner window 2 is pushed in the direction of arrow A, the pinion 22 in the housing 21 embedded in the window frame 4 is provided with the rack 10 installed in the outer window 2 '. It rotates in a clockwise direction about the shaft 23, the stopper 24 is a hinge portion supported by the pin 25 so that the free end 24b is pushed out of the gear 22a of the pinion 22 The rotation is easily performed around the 24a. Accordingly, the pinion 22 can be freely rotated without the gear 22a of the pinion 22 being caught by the free end 24b of the stopper 24, so that the inner window 2 has its arrow. It can be moved in the A direction and closed. The closing operation is the same when the outer window 2 'is moved in the opposite direction to the arrow A with respect to the inner window 2, so that the windows 2 and 2' can be closed both indoors and outdoors.

FIG. 5 shows that when the window 2 is pushed in the direction of arrow B to open the inner window 2 while the windows 2, 2 'are closed, the window 2 is not pushed and remains in the closed state. That is, in order to push the window 2 in the direction of arrow B in the opening direction opposite to the closing direction, the pinion 22 is engaged with the rack 10 and thus needs to be rotated counterclockwise, and the stopper 24 has a spring ( 26, the free end 24b must be rotated together to engage the gear 22a of the pinion 22, but as shown in the figure, the stopper 24 stops 21d of the housing 21. ), The pinion 22 is prevented from rotating in that direction because the gear 22a of the pinion 22 is caught and restrained by the free end 24b of the stopper 24. Therefore, the window 2 does not move in the open direction and eventually does not open. Of course, the function of the one-direction (counterclockwise) rotation control of the pinion 22 is effective only in a state where the pull string 28 is not pulled, and the same is true when the outer window 2 'is to be opened. This function is released by pulling the pull string 28 as will be described later, the both sides (2, 2 ') of the both sides are closed or slightly open so that people can not pass through the pull string 28 outside Since they cannot be pulled from, the outsider will not be able to open the windows (2,2 ').

On the other hand, when pulling the pull string 28 in the state as shown in Figure 5, as shown in Figure 6, the pull string 28 in the direction of the arrow C indicating the front by the round bar 32 of the guide 30 The stopper 24, which is pulled and tied at the end thereof, is pulled so that the free end 24b of the stopper 24 is completely out of the gear 22a of the pinion 22. Accordingly, the pinion 22 can be freely rotated in any direction without being caught by the free end 24b of the stopper 24, thereby moving the inner window 2 or the outer 2 'in the direction of the arrow B'. I can open it. As described above, the pull line 28 can only be pulled indoors, so the windows 2, 2 'can be opened only by the insider, not the outsider. When the pull string 28 is pulled out, the spring 27 pressed between the inner surface of the housing 21 and the stopper 24 is restored to bring it back to the state shown in FIG. 4 and to open the windows 2, 2 '. The state as shown in FIG. 5 is prevented from being opened by an outsider.

If necessary, the insider pulls the hook 40 at the end of the pull string 28 and hangs on the hook pin 41 to maintain the state as shown in FIG. 6 without pulling the pull string 28 one by one. ') Can be easily opened and closed.

In the above embodiment, the rack 10 and the pinion 22 have been described with reference to the preferred structure applied to the two windows 2, 2 'which are opened and closed by overlapping the inside and the outside. Such an embodiment may be applied to the same case when one of the two windows is fixed, and in this case, the rack and the pinion may be installed in the opening and closing windows and the window frame supporting the same. The present invention is also applicable to a single or four pair sliding windows not shown and can be installed on sliding doors for access. And the housing that accommodates the pinion and the stopper, etc. and their installation structure may be provided in various ways depending on the installation environment of the window or door.

As described above, the opening prevention device of the sliding window for crime prevention according to the present invention, so that the window can not be opened arbitrarily from the outside, even if you forget to lock or leave a separate locking device can prevent the outsider's chip. In addition, even if the window is slightly open for ventilation, even though it can be closed by an outsider, it can be assured that it will no longer open in its current state. Therefore, the present invention improves the stability of the window and it is safe to open it slightly for ventilation, so that it is possible to fully utilize the original function of the window without worrying about the intrusion of outsiders. In addition, according to the present invention, it is not possible to open the window from the outside, so it is possible to exclude a separate locking device. It only has to close from the outside, so it is more effective for users.
