<p><P>PROBLEM TO BE SOLVED: To prevent a finger-pinched accident by surely solving the problem caused by a difference in pressure between the inside and outside of a room, and to facilitate an opening/closing operation of a door, through the use of a structurally simple device for assisting the opening/closing of the door. <P>SOLUTION: The device for assisting the opening/closing of the door is installed for assisting the opening/closing of the door 1 for partitioning a space with the difference in pressure between the inside and outside of the room. The device for assisting the opening/closing of the door serves as an auxiliary door 5 which is provided on the indoor side of the door 1 in such a manner as to correspond to the door 1, and which is opened/closed in a driven manner along with the opening/closing of the door 1 by a device 7A interlocking with the opening/closing of the door. The device 7A can be composed of a driving gear 8 which is provided on a rotating shaft 3, and a driven gear 9 which is provided on a rotating shaft 6 rotating along with the opening/closing of the auxiliary door 5 and which directly meshes with the driving gear 8. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
