Description

  The present invention is a crescent lock security device that locks the crescent lock using the gap formed between the crescent lock receiver and the outer window glass and the recess of the base of the crescent lock. .

  Many intruders make a small hole in the window glass and unlock the crescent lock from the hole. In a conventional security device for preventing an intrusion crime, in the case of a locking device with a pull-out key, there is a risk that it will not be able to go out in an emergency if the extracted key is lost. In addition, in the case of a security device for security of a crescent lock to be attached to a window frame, it cannot be used if the complicated work required to attach the security device cannot be performed, and in addition, rental housing to damage the window frame etc. In the case of, repair costs may be charged when leaving the room.

  For security purposes, it is desirable to lock the windows etc. strictly when going out, but sometimes you can go outside when you are at home, so you need a security device that can lock the windows etc. tightly and easily attach / detach / lock. there were. Especially for disaster prevention, when a disaster or emergency situation occurs with a security device attached to the crescent lock at home, a security device that allows anyone to easily unlock the crescent lock without attaching a pull-out key is required Met. Moreover, in rental housing, a detachable crime prevention device that does not damage the housing fixture by fixing the crime prevention device to the window frame or the like with screws or adhesive tape is necessary. Therefore, the crescent lock is put on the crescent lock by a unique method, the crescent lock security device is fixed using the structure of the crescent lock, and the latch or patchon lock installed on the fixing plate 2 or the bottom plate 4 is appropriately locked. By locking with a similar object 6 and then covering 6 with Velcro (registered trademark) 7 and fastening, a crescent lock crime prevention device which is easy to attach and detach and does not damage housing equipment can be achieved, and the above-mentioned drawbacks are to be solved. It is.

  In the present invention, the fixing plate 1 is inserted into the gap between the receiving plate of the crescent lock and the outer window glass, and the fixing plate 2 is fixed on the recess of the base of the crescent lock, and is locked by the fixing plate 3. By preventing the crescent lever 10 of the crescent lock from being lowered and locking the appropriate key or similar object 6 such as a latch or patch on the fixing plate 2 or the bottom plate 4, the crescent lock crime prevention without damaging the window frame etc. This makes it possible to fix the device, and solves the above-mentioned drawbacks of attaching and detaching or locking and unlocking housing fixtures such as window frames.

  By attaching the main body in the form of a cube, etc., having a fixed plate 1, a fixed plate 2, a fixed plate 3 and a bottom plate 4 to a size that is almost exactly the same as the crescent lock, the main body can be mounted vertically and horizontally. Made it difficult to move and remove.

  Easy to open and close with a fixed plate 2 or bottom plate 4 such as a latch or a patch or lock, or an appropriate key 6 or the like, and a Velcro 7 that covers it. It was possible to attach and detach and lock, and it took a lot of time and effort for an intruder to unlock from a small hole such as a window glass, thereby solving the problem of crime prevention and disaster prevention.

  As described above, the crescent lock security device of the present invention has a security function improved by attaching the security device to the crescent lock of the window frame, and does not require a complicated work for installing the security device. Even in houses, it is economical without damaging window frames. Also, anyone can attach and detach, and since it is not a pull-out key, anyone can easily lock and unlock it in the event of a disaster or emergency, which can be useful for disaster prevention.

  At a minimum, it has the fixed plate 1, the fixed plate 2, the fixed plate 3, and the bottom plate 4, has the fixed plate 2 on the right or left side of the fixed plate 1, and the fixed plate 2 or the bottom plate 4 opens and closes. A form such as a cube that is locked with an appropriate key or the like 6 such as a latch or a patchon lock. The position of the fixing plate 2 is the right side of the fixing plate 1 when the crescent lock is attached to the right side of the sliding window frame, and the left side of the fixing plate 1 when the crescent lock is attached to the left side. Further, by covering the outside of the main body with Velcro (registered trademark) 7, it is further difficult to unlock the intruder and it can be troublesome.

  An embodiment will be described below with reference to the accompanying drawings. In this embodiment, the crescent lock is attached to the right side of the sliding window frame. The present embodiment is a box-shaped crescent lock security device. Reference numeral 1 denotes a fixing plate that is inserted into a gap between the receiving member of the crescent lock and the outer window glass. Reference numeral 2 denotes a fixing plate that is fixed on the recess of the base of the crescent lock. Reference numeral 3 denotes a fixing plate that prevents the crescent lever 10 from being lowered. 4 is a bottom plate that can be opened and closed. 5 is a side plate connecting 1 and 3. A cube containing 1, 2, 3, 4, 5 is the main body.

  With the crescent lock locked, remove the Velcro (registered trademark) 7 attached to the main body, and unlock the appropriate key or similar object 6 such as a latch or patch on the bottom plate 4, The fixing plate 1 is inserted into the gap between the receiver of the crescent lock and the outer window glass, and the main body is pulled to the window frame of the window. Next, the position of the main body is lowered little by little, and the fixing plate 2 is fixed on the recess of the base of the crescent lock to fix the whole main body.

  The bottom plate 4 that is opened and closed by a hinge 8 is closed, and is locked with an appropriate key 6 or the like 6 such as a latch or patch lock installed on the bottom plate 4.

  Furthermore, the magic tape (registered trademark) 7 is hung on the top plate from the bottom plate 4 and covered and stopped, thereby making it difficult for an intruder to unlock.

  Since one embodiment of the present invention is configured as described above, it can be easily locked, and it is difficult for an intruder to unlock, but anyone can easily remove it from the room, such as a window frame.
