<p><P>PROBLEM TO BE SOLVED: To provide an auxiliary device for door opening and closing which can be easily assembled and set to a right timing for urging the device. <P>SOLUTION: The auxiliary device 10 for door opening and closing comprises a turning lever 20 interlocked with the opening and closing operation of a door 2 at a side of refrigerator body 3; a spring member 40 for giving an accumulated elastic deformation transmitted by the rotation of the lever 20 when the door 2 is turned to the opening direction and also for generating an urging force on the door 2 through the lever 20 by using its elastic return force; and a switching mechanism (a stopper mechanism 80 and relay member 30) for disconnecting a mechanical connection between the lever 20 and the spring member 40 for generating the urging force while the spring member 40 for generating the urging force is kept to the state of accumulated elastic deformation by mechanically connecting the lever 20 to the spring member 40 for generating the urging force when the door 2 is located between a fully closed position and a half opened position of the door and the spring member 40 for generating the urging force is kept to the state of the accumulated elastic deformation when the door 2 is located at an open position beyond the half opened position. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
