BACKGROUND OF THE INVENTION
The present invention relates to an electric lock adapter device that converts a signal of one signal format into a signal of another signal format in signal transmission of an electric lock system that can be locked and unlocked by a push button operation or the like from the inside.
[0002]
[Prior art]
A conventional electric lock adapter device will be described with reference to FIGS. FIG. 3 is a configuration diagram of the electric lock system. FIG. 4 is a perspective view of the electric lock adapter device.
[0003]
Conventionally, an electric lock system has an electric lock 1 and an operating device 2. The electric lock 1 is provided on the end surface of the door member 1 that faces the door frame member when the door member 3 is closed, and the door is closed by being pressed by a trigger (not shown) provided on the door frame member. And an open / close detection unit having a predetermined area for detecting this and a dead bolt drive unit for moving the dead bolt forward and backward based on a drive signal from the operation unit 2.
[0004]
By the way, there are two types of connection between the electric lock 1 and the operation device 2 of the electric lock system, which are connected by so-called 6-wire pulling, and those which are connected by 2-wire and perform multiplex transmission.
[0005]
In the beginning, a six-wire electric lock system was laid, but the door member 1 was provided with an operation device 2 installed indoors or the like, leaving an electric lock for six-wire drawing. You may want to replace it with a wire type.
[0006]
In this case, as shown in FIG. 3, there is an electrical connection between a 6-wire signal line 5 that transmits and receives a signal of the first signal format and a 2-wire signal line 6 that transmits and receives a signal of the second signal format. By interposing the lock adapter device 4, it is possible to connect the rough pulling 6-wire electric lock and the 2-wire operating device 2.
[0007]
As shown in FIG. 4, the electric lock adapter device 4 includes an unlocking / locking detection circuit, an electric lock control circuit, and a transmission / reception circuit for transmitting / receiving signals to / from a two-wire signal line. A printed circuit board on which etc. are mounted is stored. The electric lock adapter device 4 has terminals 4 a and 4 a for connecting the two-wire signal line 6 on one surface thereof, and a connector 4 b for connecting to the six-wire signal line 5.
[0008]
The electric lock adapter device 4 converts the signal received from the operation device 2 via the two-wire signal line 6 and transmits it as a drive signal to the electric lock 1 via the six-wire signal line 5. In addition, the electric lock adapter device 4 converts the status signal received from the electric lock 1 via the six signal lines 5 and transmits the signal to the operation device 2 via the two-wire signal line 6.
[0009]
As described above, by using the electric lock adapter device 4, it is possible to connect and use the six-wire electric lock and the two-wire operation device 2.
[0010]
[Problems to be solved by the invention]
However, in the electric lock adapter device 4 shown in FIG. 4 as described above, the casing is, for example, a simple rectangular parallelepiped, and when the electric lock adapter device 4 is installed, the casing is installed in the ceiling or the wall. It was rolled up and placed.
