Description

[Detailed Description of the Invention] The present invention relates to the structure of a joystick device with a stopper used in a control or steering device.

In general, a joystick device that can move a handle or the like in any direction on a horizontal and vertical plane has the function of tilting the handle in all directions from a reference position and the function of automatically returning to the reference position. It was difficult to fix it in this position. For this reason, when it is desired to hold a value at an arbitrary position for a long time, the operator must continuously hold the handle at the required position, which causes the value at the holding position to fluctuate.

An object of the present invention is to provide a joystick device with a stopper that eliminates such drawbacks and allows a handle, etc., to be permanently fixed at any position.

The structure of the joystick device with a stopper of the present invention includes: a spherical body fixed to the mounting surface of the joystick and consisting of a series of rotational positions at a certain point on the axis of the joystick; First and second stays are provided with long grooves in a partially spherical body concentric with the spherical member, and sandwich the spherical member from the inside and outside across the long grooves; The present invention is characterized in that it includes a spherical stopper consisting of screws and nuts that are tightened from both sides on the joystick shaft, and the joystick shaft is fixed by tightening the screws and nuts in arbitrary directions and angles.

In this invention, a spherical body centered on the movable center of the joystick shaft and two stays that are equal to the inner and outer surfaces of the spherical surface of this spherical body are connected to each other through the handle of the joystick shaft using a special screw and a special nut. The joystick shaft can be fixed at any position by assembling the joystick from the inner and outer surfaces outside the spherical surface and tightening the special screws and special nuts.

The present invention will be explained in detail below with reference to the drawings.

Figure 1 is a side sectional view of the present invention in use, Figure 2 is its plan view, Figure 3 is a perspective view of Figure 1, Figure 4 is an exploded perspective view of the main parts of Figure 1, and Figure 5. 2 is a perspective view of the attachment portion of FIG. 1. FIG. In the figure, a joystick body 1 is fixed to a mounting plate 12 of the device with potentiometers 10 and 11 movable in orthogonal directions, and can be moved in any direction by a handle 2 of the joystick. The fixing structure of this joystick consists of a spherical main body 3 fixed on a mounting plate 12 and with approximately the upper half cut out, grooved stays 4 and 5 that sandwich this spherical main body 3 from the outer circumference and inner surface, respectively, and these stays 4, It consists of a special screw 6 and a nut 7 that tighten the screw 5 from the inside and outside. Although a lever 8 is provided to make it easier to rotate the nut 7, this may be omitted. A spherical main body 3 is provided on the reference fulcrum of the handle 2 of this joystick device 1, and this spherical main body 3
The stays 4 and 5 intersect with the inner and outer surfaces of the handle 2, and the handle 2 is assembled with a special screw 6 and a special nut 7.

With this structure, when the handle 2 of the joystick device is tilted to an arbitrary position, the stays 4 and 5 assembled with the special screw 6 and the special nut 7 automatically slide. When it is necessary to maintain fixation in a certain position, the handle of the joystick can be fixed in an arbitrary position by rotating and tightening a lever 8 fixed to a special nut 7. This special nut 7
When loosened, the structures 3 to 5 are spherical and can be tilted in any direction. Note that the special nut 6 prevents rotation of the shaft of the handle 2.

As explained above, with the joystick structure using the spherical stopper structure of the present invention,
A handle, etc. that is tilted in any direction and angle from a reference position can be fixed at any position.
