Title: Airtightness holding device of door
Inventor: UEDA SHINJI
IPC: B61D19/02
Filed: 1995-06-28
Abstract: PURPOSE: To avoid enlargement of a cylinder device and an increase in weight by arranging a pressing down part to press a door to the airtight packing side on an extending end of a link member arranged on a piston rod, and setting a rotary position projecting to the maximum extent in the door pressing direction or a position in the vicinity of it as an airtightness acting position in the pressing down part. CONSTITUTION: A link member 5 to press a door 1 is arranged on a piston rod of a cylinder device 4 through a converting means to convert advancing retreating motion into rotary motion. A pressing down part 25 to press the door 1 to the airtight packing 3 side is arranged on an extending end from a rotatably journalled base part in the link member 5. In the pressing down part 25, a rotary position projecting to the maximum extent in the door pressing direction by rotation of the link member 5 or a position in the vicinity of its rotary position is set so as to become an airtightness acting position. As a result, when the link member 5 exists in an airtightness holding position, since it is a dead point position or a position close to it, force to maintain its position become unnecessary or becomes almost unnecessary. A stroke of the cylinder device 4 can also be shortened.
