The present invention relates to a handle locking device for a special door. In the handle locking device for a special door, a first circular gear and a handle are combined with a supporting shaft installed on a door. A driving pinion is combined and geared with the first circular gear in order to be able to rotate. A first driving gear and a second driving gear are combined and geared with the driving pinion. A transmission member is installed on one surface of each driving gear in order to connect the driving gear with a locking unit where a fixating rod is placed. Therefore, the locking unit performs a vertical up-and-down motion by controlling the handle in order to lock or unlock the door. In a second circular gear, a fixating unit is included in order to be combined and geared with the driving pinion. A handle locking unit is formed to fixate the handle by being inserted or withdrawn into or from the fixating unit of the second circular gear. As described above, the handle locking unit for a special door has an improved locking structure for a special door compared with the conventional hanged type special doors in order to include the handle locking unit which can fixate the handle when the door is opened by controlling the handle. Therefore, the handle locking unit for a special door can prevent dents or bending of each component due to bumping into the frame of the door and can allow a user to easily open or close the door. |
