Operating device

Abstract

The present invention provides a moving apparatus capable of efficiently utilizing work space on a desk, and stabilizing an operating load. The present invention includes a placing portion to place a personal computer, a moving portion to move the personal computer from a use position for using the personal computer to a non-use position different from the use position, and a fixing device to detachably fix the moving portion to a desk. The position of the placing portion is determined by the length of an extension mechanism. The positioning operation to determine the length of the extension mechanism is performed by an operating device that transfers the displacement magnitude of an operating portion to an action portion by hydraulic pressure. The operating load is stabilized because the displacement magnitude is transferred by hydraulic pressure.

1 . An operating device comprising:
 a pressurizing operation means to apply pressure to a fluid pressure communicating medium according to a displacement of an operating member by an external operation;   an action means to convert and operate the pressure applied by said pressurizing operation means into a switching operation of a position fixed state and a position released state of a positioning means; and   a conducting channel to guide the pressure communicating medium from said pressurizing operation means to said action means;   wherein said conducting channel is a flexible conducting tube; and   positions for installing said pressurizing operation means and said action means can be moved relatively.   
   
   
       2 . An operating device comprising: a platform, a placing portion having a placing face to place an object, an elevation oscillating member comprising a rear end portion oscillatably connected to said platform and a front end portion oscillatably connected to said placing portion, an extension mechanism located between said elevation oscillating member and said platform, and a switching means to switch the extension position of said extension mechanism to a lock state and a release state that allows extension;
 wherein said elevation oscillating member, said platform, and said extension means comprises a triangular link structure;   the operating device comprising;   a pressurizing operation means to apply pressure to a liquid pressure communicating medium according to a displacement of an operating member by an external operation;   an action means to output the pressure applied from said pressurizing operation means as an operating pressure for a switching operation of said switching means; and   a conducting tube with flexibility to guide the liquid pressure communicating medium from the pressurizing operation means to said action means.   
   
   
       3 . The operating device according to  claim 1 , wherein said pressurizing operation means is a piston that advances and retreats according to the displacement of the operating member, and a cylinder filled with a liquid pressure communicating medium. 
   
   
       4 . The operating device according to  claim 2 , wherein said pressurizing operation means is a piston that advances and retreats according to the displacement of the operating member, and a cylinder filled with a liquid pressure communicating medium. 
   
   
       5 . The operating device according to  claim 1 , wherein said action means has a piston which the pressure from said pressurizing operation means is applied, a cylinder which stores said piston and is filled with a liquid pressure communicating medium, and an acting member which advances and retreats along with said piston as a unit. 
   
   
       6 . The operating device according to  claim 2 , wherein said action means has a piston which the pressure from said pressurizing operation means is applied, a cylinder which stores said piston and is filled with a liquid pressure communicating medium, and an acting member which advances and retreats along with said piston as a unit. 
   
   
       7 . The operating device according to  claim 1 , wherein said pressure communicating medium is oil;
 said positioning means is an opening and closing means to open and close a communicating channel connecting a space in the cylinder divided into two by a piston in an extension mechanism having a cylinder filled with fluid and a piston reciprocatably stored in the cylinder; and   said opening and closing means is opened and closed by said action means.   
   
   
       8 . The operating device according to  claim 2 , wherein said pressure communicating medium is oil;
 said positioning means is an opening and closing means to open and close a communicating channel connecting a space in the cylinder divided into two by a piston in an extension mechanism having a cylinder filled with fluid and a piston reciprocatably stored in the cylinder; and   said opening and closing means is opened and closed by said action means.
