POWER CONNECTION MECHANISM FROM DOOR IMPOSITION UNIT

Japanese Patent JP2016151140

A

PROBLEM TO BE SOLVED: To automatically perform the fine adjustment of a rotating body in an axial direction which is fit to a fixed cylinder of a lock box responding to a door thickness when a door imposition unit is attached to a wall face of a door.SOLUTION: In a power connection mechanism from a door imposition unit which is connectively interposed between an output part in a lock box which is fixedly assembled into a free end of a door, and an input part of a door imposition unit which is attached to a wall face of the door, and transmits input from the input part to the output part, the power connection mechanism is composed of: a fixed cylinder which is fixed to the lock box, and has a horizontal fitting hole at a center part; a first rotating body which is fit to the fixed cylinder, and has an outer-end engagement part which is engaged with the input part; a second rotating body which is similarly fit to the fixed cylinder, whose one end cooperatively is engaged with an inner end of the first rotating body, and cooperatively rotates together therewith, and whose other end is engaged with the output part; and a resilient member which is interposed between the second rotating body and the first rotating body, and elongates and contracts in a door thickness direction with respect to a distance between a position of the output part and the wall face when the door imposition unit is attached to the wall face of the door.SELECTED DRAWING: Figure 1
