Claims9
A shade suspension apparatus comprising:
- a hanger (10) disposed on a portion of a ceiling adjoining a wall and having a plurality of guide rollers (11);
- a main adjustor (20) comprising:
- a main housing (21) disposed on a portion of the wall below the hanger (10) and having an inner space (21b);
- a rotary shaft (22) axially rotating in the inner space (21b) of the main housing (21);
- a rotary body (23) axially attached to a portion of the rotary shaft (22) and rotating integrally with the rotary shaft (22) along an axial direction when a pulling cord (23a) is manipulated;
- a plurality of winding reels (24) axially attached to another portion of the rotary shaft (22) and rotating integrally with the rotary shaft (22) along an axial direction, wherein the winding reels are wound with suspension cords (24a) on an outer circumferential surface thereof, the suspension cords guided by guide rollers (11) of the hanger (10) and connected to a shade rod (5);
- and
- a control brake (25) connected to an end of the rotary body (23) to control an axial rotation speed of the rotary body (23);
- a plurality of sub-adjustors (30) disposed on the wall and spaced apart from each other by a predetermined distance, wherein each of the plurality of sub-adjustors (30) comprises:
- an auxiliary housing (31) having an inner space (31a), an open hole (31b) in an outer circumferential surface, and a guide roller (31c) in the inner space (31a);
- a suspension member (32) with a top end connected to the corresponding suspension cord and a bottom end connected to the shade rod (5);
- an opening/closing member (33) supporting or releasing the suspension member (32);
- and
- a fastener (34) coupled to a top end of the auxiliary housing (31) and attached to the ceiling;
- and
- an opening/closing controller controlling the opening/closing member (33).
