- some may use an extension mechanism consisting of a cylinder and a piston.
- the length of the overall extension mechanism changes when the piston moves within the cylinder, and the overall length of the extension mechanism is determined according to the position of the piston.
- inside the cylinder which is divided into two by the piston is in communication with front and back faces of the piston by a communicating channel, and fluid in the cylinder moves in the communicating channel along with the movement of the piston.
- a valve to be opened and closed is provided inside the communicating channel, and by closing this valve, the movement of the piston is fixed, thereby the overall length of the extension mechanism is fixed.
- this valve is performed by an operating button protruding to the top end of the piston rod, and configured such that the valve is opened by pressing the button, thereby the piston can be moved, and the valve is closed when the button is restored, thereby the position of the piston is fixed.
- an operating device to operate a button has a operating portion provided with a lever and the like, a communicating mechanism to communicate the operating amount of the operating portion to the button, an action portion to act the operating amount of the operating portion to the button. Because the operating porting is arranged on the lower side of the tray and the action portion is provided to the front end of the piston rod, relative position of the operating portion and the action portion changes when the tray of the elevating apparatus is moved vertically.
- the conventional communicating mechanism is a mechanism consisting of an inner wire and an outer wire, and configured such that the operating amount is communicated by operating the inner wire stored inside the outer wire in an axial direction.
- the inner wire and the outer wire have flexibility, and are configured to change form according to the change in relative position of the operating portion and the action portion.
- these wires are in a linear form in the normal shape, and a restoring force is generated to restore to the original form when the wires are bent according to the position of the tray of the elevation apparatus. Because this restoring force acts on the elevation apparatus with wires attached, there is a problem of making the elevating operation of the tray heavy or light.

- the placing portion may be moved vertically by sliding the elevation oscillating member as a fixing release state of the extension means. By moving the placing portion, the angle of the placing portion and the elevation oscillating member changes, thereby the relative position of the pressurizing operation means on the placing portion side and the action means on the elevation oscillating member side changes. Even when such a change in the relative position occurs, the pressure communicating medium is guided though the flexible conduction tube, thereby the bend of the conduction tube does not obstruct the elevation operation of the placing portion, and also the operating load is maintained in a stable fashion.

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.
Description
- The present invention relates to an operating device, more specifically, an operating device in which the relative position of an operating portion and an operating object portion changes.
- Generally, office workers work with a personal computer (PC) placed on their desks. For example, in the case of a desk-top type computer, at least a display and a keyboard, in some cases the computer main unit, are placed on a desk. In addition, in the case of a laptop-type computer, the entire laptop is placed on a desk.
- However, office workers are not always using their PC when they are working. For example, when reading a document or taking notes while on the phone, the time when not using a computer is not necessarily short. Thus, if a PC is placed on a desk even when it's not in use, it takes up working space on the desk.
- In order to solve such issues, an elevating apparatus which places the PC on a tray and moves the tray vertically, is proposed. In this apparatus, the tray is lowered when using the PC and the tray is raised to secure working space on the desk when the PC is not in use.
- [Patent document] Japanese Unexamined Patent Application No. 2000-135123.
- Among such elevating apparatuses, some may use an extension mechanism consisting of a cylinder and a piston. In such an extension mechanism, the length of the overall extension mechanism changes when the piston moves within the cylinder, and the overall length of the extension mechanism is determined according to the position of the piston. Also, inside the cylinder which is divided into two by the piston is in communication with front and back faces of the piston by a communicating channel, and fluid in the cylinder moves in the communicating channel along with the movement of the piston. A valve to be opened and closed is provided inside the communicating channel, and by closing this valve, the movement of the piston is fixed, thereby the overall length of the extension mechanism is fixed.
- The operation of this valve is performed by an operating button protruding to the top end of the piston rod, and configured such that the valve is opened by pressing the button, thereby the piston can be moved, and the valve is closed when the button is restored, thereby the position of the piston is fixed.
- Conventionally, an operating device to operate a button has a operating portion provided with a lever and the like, a communicating mechanism to communicate the operating amount of the operating portion to the button, an action portion to act the operating amount of the operating portion to the button. Because the operating porting is arranged on the lower side of the tray and the action portion is provided to the front end of the piston rod, relative position of the operating portion and the action portion changes when the tray of the elevating apparatus is moved vertically.
- The conventional communicating mechanism is a mechanism consisting of an inner wire and an outer wire, and configured such that the operating amount is communicated by operating the inner wire stored inside the outer wire in an axial direction. Also, the inner wire and the outer wire have flexibility, and are configured to change form according to the change in relative position of the operating portion and the action portion.
- However, these wires are in a linear form in the normal shape, and a restoring force is generated to restore to the original form when the wires are bent according to the position of the tray of the elevation apparatus. Because this restoring force acts on the elevation apparatus with wires attached, there is a problem of making the elevating operation of the tray heavy or light.
- Also, friction is generated between the inner wire and the outer wire when the wires are bent, and the friction force changes according to the amount of bend of the wire, resulting in a problem of unstable operating load (force (load) necessary for an operator to operate the operating portion) of the operating portion.
- The present invention is made with a view of the above facts and its objective is to propose a moving apparatus which allows an operator to effectively utilize work space on a desk, and has a stable operating load.
- Such an objective can be achieved by the present invention described below.
- An operating device consisting of a pressurizing operation means to apply pressure to a liquid pressure communicating medium according to the displacement of an operating member by an external operation, an action means to convert and operate the pressure applied by the 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 the pressurizing operation means to the action means, wherein the conducting channel is a conducting tube with flexibility, and positions for installing the pressurizing operation means and the action means can be moved relatively.
- An operating device for attaching to a moving apparatus consisting of a platform, a placing portion having a placing face to place a placing object, an elevation oscillating member comprising a rear end portion oscillatably connected to the platform and a front end portion oscillatably connected to the placing portion, an extension mechanism located between the elevation oscillating member and the platform, and a switching means to switch the extension position of the extension mechanism to a lock state and a release state that allows extension, wherein the elevation oscillating member, the platform, and the extension means comprises a triangular link structure, and the operating device consisting of a pressurizing operation means to apply pressure to a liquid pressure communicating medium according to the displacement of an operating member by an external operation, an action means to output the pressure applied from the pressurizing operation means as an operating pressure for the switching operation of the switching means, and a conducting tube with flexibility to guide the liquid pressure communicating medium from the pressurizing operation means to the action means.
- The pressurizing operation means is a operating side piston that advances and retreats according to the displacement of the operating member, and an operating side cylinder filled with a liquid pressure communicating medium.
- The action means has an acting side piston which the pressure from the pressurizing operation means is applied, an acting side cylinder which stores the acting side piston and is filled with a liquid pressure communicating medium, and an acting member which advances and retreats along with the acting side piston as a unit.
- The pressure communicating medium is oil, the positioning means is a opening and closing means to open and close a communicating channel connecting the space in the cylinder divided into two by the piston in an extension mechanism having a cylinder filled with fluid and a piston reciprocatably stored in the cylinder, and the opening and closing means is opened and closed by the action means.
- The communication of the operating pressure from the pressurizing operation means to the action means is performed though the pressure communicating medium which is a fluid, the operating pressure is communicated to the action portion and the pressure required for operation is stabilized even when the conduction channel is deformed due to a change in the relative position of the pressurizing operation means and the action means. The placing portion may be moved vertically by sliding the elevation oscillating member as a fixing release state of the extension means. By moving the placing portion, the angle of the placing portion and the elevation oscillating member changes, thereby the relative position of the pressurizing operation means on the placing portion side and the action means on the elevation oscillating member side changes. Even when such a change in the relative position occurs, the pressure communicating medium is guided though the flexible conduction tube, thereby the bend of the conduction tube does not obstruct the elevation operation of the placing portion, and also the operating load is maintained in a stable fashion.
- An amount of the displacement of the operating member is communicated to the action means through the pressure communicating medium by moving the piston with the operating member, thereby the amount of the displacement of the operating side can be communicated accurately to the action portion side. The acting side piston converts the amount of displacement of the operating side communicated though the pressure communicating medium into the operation displacement, thereby the amount of the displacement of the operating side can be accurately acted as the displacement of the acting side. The length of the extension mechanism can be adjusted to an arbitrary length by configuring the extension mechanism with the cylinder and the piston. Also, by using the opening and closing means to open and close the distribution channel to insert the piston as a lock mechanism, the length can be fixed at an arbitrary position. Further, by using oil as a pressure communicating medium, the operation displacement of the pressure operating means side can be accurately communicated sequentially to the action means side, thereby the open-close operation of the opening and closing means may be performed with high accuracy.

Theaction portion 4C is provided with an action portionmain body 41C, a connectingportion 42C to connect and fix the top end of thepiston rod 52 in theextension mechanism 5, and apiston 44C. Acylinder 43C is formed inside the action portionmain body 41C, and thepiston 44C is stored in thecylinder 43C. Also, theoperating button 53 of thepiston rod 52 connected through theconnection portion 42C is inserted into thecylinder 43C, and attached to a face on one side of thepiston 44C. On a face on the other side ofpiston 44C, an oil chamber filled with oil is formed by thecylinder 43C and thepiston 44C (FIG. 5 shows a condition where the oil is pressed out). - A communicating
channel 45C is connected to thecylinder 43C and a conductingtube 42B which is connected through the connectingportion 43B is connected to the communicatingchannel 45C. The conductingtube 42B is a tubal body formed with a flexible material, for example, it may be formed by synthetic resin. By configuring the conductingtube 42B with a soft material, a decrease in the resistance against deformation is achieved, thereby suppressing any excess resistance from occurring when performing the elevation operation of the placingportion 18. Oil is filled in thecylinder 43A on theoperating portion 4A side, thecylinder 43C on theaction portion 4C side, and the conductingtube 42B, as a pressure communicating medium. - Action of the
operating device 4 configured as described above is hereinafter explained. When hooking a finger on thefinger hook 471A and pulling the finger, the operatingmember 47A presses thepiston rod 45A in. As a result, thepiston 44A on theoperating portion 4A side is pressed by thepiston rod 45A, and the oil is pressed out from thecylinder 43A. The pressed out oil flows into thecylinder 43C on theaction portion 4C side by conductingtube 42B, pressing out thepiston 44C, and pressing theoperating button 53 in. As a result, the lock on theextension mechanism 5 is released, thereby the placingportion 18 can be moved vertically. The lock released state can be maintained by maintaining the state where theoperating button 53 is pressed constantly. - As shown in
FIG. 1 , the amount of bend of the conductingtube 42B is different for the condition where placingportion 18 is lowered to the desk (use position (A)), the condition where lifted to an upper most position (upper most position (B)), and the condition where fixed on a position in the middle (middle position C)). In a configuration to communicate the operating displacement by a wire, the operating pressure changes by the difference in the amount of bend, and it is unstable. This is thought to be because the contacting pressure between an inner wire and an outer wire changes by bending the wires. - In the present invention, the medium to communicate the operating pressure is fluid, the operating pressure (the force necessary to pull the operating member) can be stabilized without being influenced by the bending amount of the conducting
tube 42B or the position of the placingportion 18. The operatingdevice 4 according to the present invention is not limited to be used in the movingapparatus 1 explained above, and it may be used to a mechanism in which the relative position of an operating portion and an action portion changes. Also, the configuration described above is explained by using the case where it is used in the lock release operation of theextension mechanism 5 as an example; however, it may be another mechanism, as long as the mechanism is configured to displace the operating portion.
