<p>#CMT# #/CMT# The door has a door blade with top and bottom segments, in which each segment has two ends facing opening and closing directions of the blade, respectively. The bottom segment with three rollers shifts its middle roller (16) in the opening direction between its ends, where the middle roller is not adjacent to the end facing the closing direction. The shifted roller is placed in a curved rail section when the blade is opened widely. #CMT# : #/CMT# The curved section is connected to horizontal and vertical sections of the rail. The rollers of each segment slide together in the opening direction of the door. #CMT#USE : #/CMT# Used for a garage. #CMT#ADVANTAGE : #/CMT# The bottom segment shifts its middle roller in the opening direction such that the shifted roller is placed in the curved section when the door blade is opened widely, thus the end of the bottom segment facing the closing direction is deflected in the direction of the ceiling. The passage dimension is thus extended without the need for extending the overall length of a rail system and without increasing the productivity of a motor driving the rail system. The door is maintained in an idle state in the opened condition. The rollers of each segment slide together in the opening direction of the door, thus minimizing the cost of the construction of the door and improving the course behavior of the rail. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an edge portion of a door. 2 : Curved rail section 4 : Horizontal section 8 : Bottom segment 14, 16, 18 : Rollers 32 : Roller guide.</p> |
