ようにした扉の開閉位置固定装置。Means and action for solving the problem A lock pin 19 supporting a roller 21 at one end is attached to one side of the door body 3 side and the support column 1 side, parallel to the shaft 8, with the roller 21 facing the other side. , a flat surface that is perpendicular to the shaft 8 and in contact with the roller 21 is provided on the other side of the door body 3 side and the support column 1 side, and a first raised part 40 and a second raised part 4 are provided on this flat surface.
1 are provided toward one side at equal distances from the center of the shaft 8 at intervals in the circumferential direction of the shaft 8, and the shafts 8 at the first raised portion 40 and the second raised portion 41
Both circumferential side surfaces 40a, 40a, 41a, 41a
is a slope inclined with respect to a right angle to the flat surface, and a first concave part 42 and a second concave part in which the roller 21 fits into the circumferential intermediate part of the shaft 8 in the first protruding part 40 and the second protruding part 41 The lock pin 19 is pressed to the other side with an elastic member to hold the roller 20 against the flat surface of the other side, and the positional relationship between the lock pin 19 and the first and second protrusions 40 and 41 is determined. When the roller 21 provided on the lock pin 19 fits into the first concave portion 42 of the first raised portion 40, the door body 3 is in the closed position, and the roller 21 provided on the lock pin 19 fits into the second recessed portion 42 of the second raised portion 41.
A device for fixing the opening/closing position of a door so that the door body 3 is in the open position when fitted into the recessed part 43.
これにより、扉体3を軸8により支柱1に対し
て上方に回動すると、ローラ21が平坦面に対し

て扉体3を閉じ位置に保持できるから、扉体3を
上方又は下方に回動する操作のみで扉体3を開き
位置と閉じ位置に保持できて扉体の開閉操作が簡
単となる。 As a result, when the door body 3 is rotated upward with respect to the support column 1 by the shaft 8, the roller 21 moves relative to the flat surface, and the roller 20 moves toward the second raised portion 41.
When the door body 3 is rotated further downward from this state, the roller 20 is disengaged from the second concave portion 43 and the door body 3 is held in the open position. Since the door body 3 can be held in the closed position by fitting into the first recessed part 42 of the part 40, the door body 3 can be held in the open position and the closed position simply by rotating the door body 3 upward or downward. This makes it easy to open and close the door.
