Description

  The present invention relates to an electronic lock, in particular, an electronic lock attached to a door provided at the entrance of a building or indoor room, and also relates to a structure for attaching an electronic lock using a wireless compatible system such as a light beam or a radio wave.

  Conventionally, a lock device with a mechanical structure is indispensable to the presence of a keyhole for inserting a key, and is easily damaged by a picking crime. Therefore, recently, electronic locks that do not require the presence of keyholes are often used. This electronic lock also uses radio waves, rays, and other wireless media, and a dedicated numeric keypad. There are those that input a recitation number or the like, or those that use physical features such as fingerprints and palms as a medium.

  Of the various types of electronic locks described above, wireless locks are the mainstream because they can be operated without contact. In addition, the electronic lock requires driving power in order to allow the eaves member (dead bolt) to enter and exit, but this power source is usually a battery because of no power outage and troublesome wiring.

By using this battery, it is necessary to replace it when the battery is exhausted. For this battery replacement operation and maintenance, the electronic lock is attached with the device exposed to the indoor side of the door. For this reason, the appearance of the door as a whole may be impaired.
