LIFTING MECHANISM AND AUTOMATIC OPENING AND CLOSING DEVICE

TANIGUCHI TERUYUKI / TAKEMURA SHIGEO / HIRAI KAZUSADA

To provide a lifting mechanism which is suitable for an opening and closing device for automatically moving an opening and closing part while further suppressing an increase in the size of the whole device than a conventional device.SOLUTION: A lifting mechanism includes: a body part formed with an opening; an opening and closing part 40 which blocks the opening and is arranged in a slide movable manner in a vertical direction D1 to the body part; a spindle 60 which is screwed to the body part, can be rotated around an axial line extending in the vertical direction D1 and advance and retreat in the vertical direction D1, and is adjacent to the opening and closing part 40 in the vertical direction D1; and a coupling mechanism 80 for coupling the opening and closing part 40 and the spindle 60. The coupling mechanism 80 couples the spindle 60 to the opening and closing part 40 so as to be relatively rotatable and be connected in the vertical direction D1.SELECTED DRAWING: Figure 3

【課題】従来の装置よりも装置全体の大型化を抑えつつ開閉部を自動的に移動させることができる開閉装置に好適な昇降機構を提供する。【解決手段】本発明に係る昇降機構は、開口が形成された本体部と、前記開口を閉塞するとともに前記本体部に対して上下方向Ｄ１にスライド移動可能に配置された開閉部４０と、前記本体部に対して螺着されて上下方向Ｄ１に延びる軸線回りに回転可能かつ上下方向Ｄ１に進退可能であり、開閉部４０に対して、上下方向Ｄ１に隣り合うスピンドル６０と、開閉部４０とスピンドル６０とを結合する結合機構８０と、を備える。結合機構８０は、スピンドル６０を開閉部４０に対して、相対的に回転自在に、かつ上下方向Ｄ１に連係された状態で結合する。【選択図】図３
