Abstract
A combined electric/manual folding door 100 of the invention comprises: a small door (60) having a pivot on one side edge, and a large door 50 foldably connected to the small door 60 via a hinge 9. The width of the small door 60 to the large door 50 is set at 1:2. A guide roller 8 is attached to an upper face central portion of the large door 50. The guide roller 8 can move freely inside a suspension rail 7 arranged parallel with the upper side of the doors 50, 60. An electric drive section 3 drives the large door 50 via a rotation rod 5. The electric drive section 3 also drives when a load is detected applied to door pulls 21, 22 for manual opening and closing, to thereby assist the manual opening and closing.
Claims17
A combined electric/manual folding door comprising:
- a first door with one edge rotatably supported by a pivot;
- a second door foldably connected to an other edge of said first door;
- a turning member connected to said second door;
- a turning mechanism for driving said turning member around a rotation axis, thereby driving said second door;
- and
- a slide mechanism which connects one end of said turning member to said second door so that a connection point of said end of said turning member and said second door is able to move along a widthwise direction of said second door.
A combined electric/manual folding door comprising:
- a first door with one edge rotatably supported by a pivot;
- a second door foldably connected to an other edge of said first door;
- a first rotation rod which is rotatable around a rotation axis provided at a position different from that of said pivot;
- a turning mechanism which turns said first rotation rod around said rotation axis;
- and
- a second rotation rod which has one end rotatably connected to said first rotation rod and an other end rotatably connected to said second door, and is shorter than said first rotation rod,
- wherein said first and second doors are folded when said first rotation rod is positioned at an end of a rotation range of said first rotation rod, and said first and second doors are extended in a plane when said first rotation rod is positioned at an other end of said rotation range.
