FORGET-TO-LOCK PREVENTION THUMB TURN COVER
PROBLEM TO BE SOLVED: To provide a forget-to-lock prevention thumb turn cover capable of preventing a thumb turn from being manipulated in a fraud manner from the outside as well as to prevent forget-to-lock of an entrance door from the inside after getting home.SOLUTION: A piece of magnet switch with one pole 5a is attached to a thumb turn cover 1 and the other piece of magnet switch with the other pole is attached to a thumb turn 2 using a double sided adhesive tape. When the thumb turn is turned, a gap between the piece of magnet switch with one pole 5a and the other piece of magnet switch with the other pole changes; thereby a switch of a battery 4 is turned ON. With this, an LED 3 is activated to emit light and sound to alarm a forgot-to-lock to a user.SELECTED DRAWING: Figure 2
【課題】外から不正な方法によりサムターンを回すことを防止すると共に、帰宅時玄関ドアを開錠し、そのまま部屋に行き、内側からの玄関ドアの施錠忘れを防止するサムターンカバーを提供する。【解決手段】サムターンカバー１に磁石スイッチの一方５ａを組込み、磁石スイッチの他方をサムターン２に両面テープで貼付け、サムターンの回転に伴う磁石スイッチの一方５ａと磁石スイッチの他方との間隔の変化で電池４のスイッチが入り、ＬＥＤライト３を点灯・音を発し施錠忘れを報せる。【選択図】図２
