[Conventional technology]

A master unit that locks windows, entrances, etc. in specific locations for building crime prevention and disaster prevention. Safety systems that allow you to check and display warnings are becoming popular. These types of Early versions of the system transmitted information from the lock sensor to the base unit via wired means. However, it is technically difficult to transmit data from a lock sensor installed on a movable part by wired means. There are also various aesthetic problems, and wireless means are required between the lock sensor and the main device. A relay system has emerged.

0003 An example of a lock detection device using the above-mentioned wireless means is disclosed in Japanese Patent Application Laid-Open No. 62-27891. Disclosed in the official gazette. Figure 3 shows the above lock detection device installed on a glass door with a sliding structure. FIG. 4 is a circuit block diagram of the same device.

0004 In FIGS. 3 and 4, sliding glass doors 13a and 13b in the window frame 11 There is a crescent lock on each vertical stile 15a, 15b that joins when completely closed. 17 rotating levers 19 and engagement claws 21 are attached. And glass door 13 The vertical stile 15b of b has a reed which is activated by locking and unlocking the crescent lock 17. A switch 22 is attached to the upper end of the vertical stile 15b. 7 is attached and connected to a reed switch 22 and a lead wire 23.

[0005] Also, on the back side of the upper door rail of the window frame 11, when the glass door is locked, the door side circuit 27 is connected. An oscillator 12 is fixed at the opposite position, and a lead wire 16 is used to determine the locked state. It is connected to a main controller 28 that performs processing such as display and alarm. The oscillator 12 receives power supply from the main controller 28, and the oscillator 1 2 is radiated from the fixed side coil 25 as electromagnetic waves. Furthermore, glass door 13 When a and 13b are completely closed, the fixed side coil 25 and the movable side coil of the door side circuit 27 are closed. It is in a state of electromagnetic coupling with the file 29. The circuit operating state of the door side circuit 27 changes depending on the operation of the reed switch 22. It consists of a movable side circuit section 33 and the above-mentioned movable side coil 29.

[0006] With the above configuration, when the glass door is not in the locked position, the fixed side coil 25 and the movable If the magnetic coupling with the side coil 29 is weak and the lock is not completely locked, the remote The movable side circuit part 33 whose circuit characteristics change depending on the operating state of the code switch 22 , the characteristics of the fixed side coil 25 and oscillator 12 will be affected, and the main controller The troller 28 checks whether the glass doors 13a and 13b are closed or completely locked. You can check whether it is.

[0007]

[Problem that the idea aims to solve]

However, in the above conventional technology, the installation space for the oscillator 12 and the fixed coil 25 is The space is extremely limited, and the movable coil 23 is small. Also, the fixed side coil 25 is also small, and the installation position must be selected to be extremely close to the movable coil 29. There was a point. Also, if you use an unreasonably large oscillator or coil, the aesthetic appearance of the window will be seriously affected. It will cause damage.

[0008] Also, of course, multiple oscillators are required to check multiple locked locations. , there was a problem in that a fixed coil was required for each oscillator.

[0009] This idea was made in order to solve the problems of the above-mentioned conventional technology. Wireless relay between the sensor side and the main device side using a lock detection device that relays wirelessly. Loop-up for lock sensors that can be extended beyond conventional models and is aesthetically pleasing. The object of the present invention is to provide a window and a window frame incorporating an antenna.
