OPENABLE DOOR OPENING/CLOSING DEVICE
To provide an openable door opening/closing device which has a simple structure, and enables self opening/closing of the door by a simple operation.SOLUTION: An openable door opening/closing device H includes: an inclined cam 42 which can freely slide in conjunction with a lifting operation of a pedal 41 of a stepping part 40; a rotary plate cam operation part which rotates a rotary plate cam; and an upper part cam 71 and a lower part cam 81 which have inclined cam surfaces 72, 82, respectively. The upper part cam 71 and the lower part cam 81 are pivotally supported by a rotary shaft 66 of the rotary plate cam so as to rotate freely in a state where the inclined cam surfaces 72, 82 are mutually opposing to each other, and the lower part cam 81 is rotatable in conjunction with the rotation operation of the rotary plate cam.SELECTED DRAWING: Figure 2
【課題】簡易な構造であり、簡単な操作により自開閉が可能となる開き扉の開閉装置を提供する。【解決手段】足踏部４０のペダル４１の昇降動作と連動してスライド自在である傾斜カム４２と、回転板カムを回動させるための回転板カム操作部と、上下一対であり、それぞれ傾斜カム面７２，８２を有する上部カム７１及び下部カム８１と、を備え、上部カム７１と下部カム８１とは、相互に傾斜カム面７２，８２が対向した状態で、回転板カムの回動軸６６に、回動自在に軸支されており、回転板カムの回動動作に連動して、下部カム８１が回動可能である開き扉開閉装置Ｈとした。【選択図】図２
