Retaining assembly for retaining releasably a door at a desired open position to a door frame |
摘要 |
A retaining assembly includes a hollow casing mounted on a door. The casing has a horizontal wall portion formed with a through-hole and an upright rotary shaft which has an end portion that extends out of the casing through the wall portion and which is rotatable relative to the casing. A coupling rod has a first end portion connected pivotally to a door frame and a second end portion connected to the end portion of the shaft so as to, drive rotatably the shaft in a first direction when the door moves relative to the door frame to an open position. A pin has an end portion which is normally biased to extend out of the casing via the through-hole. An elongated positioning plate has a first end portion and a second end portion which is coupled releasably and selectively to the end portion of the shaft such that the first end portion is displaced by a variable initial angle, corresponding to the open position, with respect to the pin when the door is in a closed position. The positioning plate is rotatable with the shaft in the first direction to a position where the pin engages the first end portion of the positioning plate by a friction force sufficient to arrest releasably rotation of the shaft in a second direction opposite to the first direction so as to retain releasably the door at the open position.
