Abstract

<P>PROBLEM TO BE SOLVED: To simplify a structure by shortening the wiring of vibration sensors, confirming the closing of a window by an alarm device, and detecting and alarming abnormal vibration by the right and left vibration sensors. <P>SOLUTION: In this locking device for the window locking left and right window frames 1, 2 by a crescent lock 4 installed at the mating part 3 of these both window frames 1, 2, the vibration sensors 7, 8 detecting the vibration of window panes 5, 6 are stuck on the window panes 5, 6 near the crescent lock 4. The alarm device 10 is installed in proximity to the crescent lock 4. When both window frames 1, 2 are set at the same closing positions, one terminal 12 of the vibration sensor 7 is continued with the alarm device 10. Since a crescent lever 11 is rotated to the closing position, the other terminal 13 is continued with the alarm device 10 to bring both vibration sensors 7, 8 in an alarm operation state. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a window locking alarm device that detects a suspicious person intrusion due to window glass destruction by confirming the complete closing of a window with a sliding window or a double door.

In order to detect the breakage of the window glass, there are ones that capture the breaking sound of the window glass with a microphone, and those that attach vibration sensors to the left and right window glasses to detect vibration when the glass breaks. As the vibration sensor, there are a capacitance type, an eddy current type, a laser Doppler type, and a pressure element type.
JP 2005-78499 A

  A microphone that captures the breaking sound of a window glass may malfunction by picking up sounds other than the glass breaking sound. Moreover, the thing using a vibration sensor sticks a vibration sensor to each of right and left glass, and requires an alarm for each.

  Therefore, the present invention simplifies the configuration by shortening the wiring of the vibration sensor, confirming the closing of the window with one alarm device, and allowing the left and right vibration sensors to detect and alarm abnormal vibration. This is the issue.

  The present invention relates to a vibration sensor 7 for detecting vibrations of window glasses 5 and 6 in a window locking device that locks left and right window frames 1 and 2 with a crescent lock 4 provided at a joint 3 of both window frames 1 and 2. , 8 are attached to the glasses 5 and 6 in the vicinity of the crescent lock 4 and an alarm device 10 is provided in the vicinity of the crescent lock 4 so that both the window frames 1 and 2 are in the closed position. The terminal 12 is electrically connected to the alarm device 10 and the other terminal 13 is electrically connected to the alarm device 10 by turning the crescent lever 11 to the closed position so that the vibration sensors 7 and 8 are in a warning operation state.

  According to the above configuration, since the vibration sensors 7 and 8 for detecting the vibration of the window glasses 5 and 6 are attached to the glasses 5 and 6 in the vicinity of the crescent lock 4, the vibration sensors 7 and 8 to the alarm device 10 are attached. The wiring is shortened, the window frames 1 and 2 are closed, and the crescent lever 11 is rotated to the closed position, whereby the alarm device 10 and the vibration sensors 7 and 8 are electrically connected to detect the closing of the window. Even if the window glass is broken, the alarm device 10 senses and notifies the alarm, so that it is inexpensive because one alarm device 10 can notify the closing of the window and watch the glass break.

Next, a description will be given with reference to the drawings showing an embodiment of the present invention.
FIG. 1 shows a sliding window. By rotating a crescent lever 12 of a crescent lock 4 in which left and right window frames 1 and 2 are provided at the upper and lower centers of both mating portions 3, both are engaged with a crescent hook 14. The window frames 1 and 2 are closed. The alarm device 10 is fixed in a support frame of one window frame 1.

  Glasses 5 and 6 are fitted into both window frames 1 and 2, and vibration sensors 7 and 8 are attached in the vicinity of the crescent lock 4. The electrical terminals 15 and 16 of one vibration sensor 7 are connected to the alarm device 10, and the electrical terminal of the other vibration sensor 8 is connected to a contact terminal 11 provided in the middle of the window frame 2 on the center side. The contact terminal 11 can be projected and retracted, and is urged toward the projecting side to contact the terminal 17 of the alarm device 10 when both the window frames 1 and 2 are closed, so that the contact terminal 11 becomes conductive.

Further, another electrical terminal of the vibration sensor 8 is connected to a contact terminal 18 provided so as to be pushed when the crescent lever is rotated to the closed position below the crescent hook 14.
Therefore, by closing the window frames 1 and 2 and turning the crescent lever 12 to the closed position, both the vibration sensors 7 and 8 are connected to the alarm device 10 and are in a warning state.

  The alarm 10 notifies the alert controller 20 that the alert state has been reached. When the glasses 5 and 6 are broken during the alert, an alarm is issued and the alert controller 20 notifies the mobile phone 22 of the house owner through the telephone 21.

It is a whole front view in the Example of this invention. It is a plane sectional view in the example of the present invention. It is a sectional side view in the Example of this invention. It is another sectional side view in the Example of this invention. It is a schematic system diagram in an embodiment of the present invention.
