Title:
DOOR OPENING/CLOSING DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/080840
Kind Code:
A1
Abstract:
Provided is a door opening/closing detecting device which is capable of transmitting a radio signal, and has a high degree of freedom in terms of mounting position. A door opening/closing detecting device (1) is a door rotation detecting device mounted on a door (10) which comprises a door main body (11), a first rotation operation member (12a), a second rotation operation member (12b), and a metal rotation shaft (13) which penetrates the door main body (11) and rotates the first rotation operation member (12a) and the second rotation operation member (12b) in conjunction with each other, the first rotation operation member (12a) being connected to one end of the metal rotation shaft and the second rotation operation member (12b) being connected to the other end of the metal rotation shaft. The door opening/closing detecting device (1) comprises a metal rotation member (21), a power generation mechanism (30), and a transmission unit (40). The rotation member (21) is rotated according to a rotation of the rotation shaft (13). The power generation mechanism (30) performs power generation according to a rotation of the rotation member (21). When power is generated by the power generation mechanism (30), the transmission unit (40) transmits a radio signal by using the power generated by the power generation mechanism (30). The transmission unit (40) comprises an antenna terminal. The rotation shaft (13) and the rotation member (21) are electrically connected to each other. The antenna terminal of the transmission unit (40) and the rotation member (21) are electrically connected to each other.
