AUXILIARY DEVICE FOR DOOR OPERATION
PROBLEM TO BE SOLVED: To provide an auxiliary device for door operation of improved convenience.SOLUTION: When opening a door 92 that closes an opening, a motor 70 is rotated normally to cause a rotor 10 rotate along with a case 60 for pressing an engaging part 12 of the rotor 10 against a first cam surface 311, causing the rotor 10 to rotate along with the case 60 to one side relative to the door 92 by reactive force from the first cam surface 311, thus moving the door 92 in an opening direction for a prescribed amount. After the door 92 moves in the opening direction for the prescribed amount, the motor 70 is reversely rotated to have the engaging part 12 of the rotor 10 pressed against a second cam surface 312, causing the rotor 10 to rotate to the other side relative to the case 60 by reactive force from the second cam surface 312, thus accumulating elastic energy in a torsion coil spring 20 for energizing the door 92 in a closing direction.SELECTED DRAWING: Figure 6
【課題】扉操作補助装置の使い勝手を向上させる。【解決手段】開口を閉鎖した状態にある扉９２を開操作する際には、モータ７０を正転させてケース６０とともにロータ１０を回転させてロータ１０の係合部１２を第一カム面３１１に押しつけることにより、その第一カム面３１１からの反作用力によってロータ１０をケース６０とともに扉９２に対して相対的に一方側に回動させて扉９２を開方向に所定量移動させ、この扉９２が開方向に所定量移動した後、モータ７０を逆転させてケース６０をロータ１０の係合部１２を第二カム面３１２に押しつけることにより、その第二カム面３１２からの反作用力によってロータ１０をケース６０に対して相対的に他方側に回動させ、ねじりコイルばね２０に扉９２を閉方向に付勢する弾性エネルギを蓄積する。【選択図】図６
