Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a joystick (control stick) used when operating a hydraulic control device such as a power shovel, an airplane, or an electronic game machine.
[0002]
[Prior art]
Conventionally, a joystick used when operating a hydraulic control device such as a power shovel, an airplane, or an electronic game machine is known. FIG. 4 is a diagram showing a conventional joystick 200. (A) shows the whole perspective view, (b) shows the structure of the grip 203 of the joystick 200. FIG. The grip 203 connected to the main body 204 is configured to be tilted in any direction of 360 degrees. The main body 204 outputs a predetermined control signal to the cord 205 according to the direction in which the grip 203 is tilted. The grip 203 includes two switches 201 and 202 on the front and rear. The switches 201 and 202 function as function keys for performing operation mode switching, setting, and the like.
[0003]
As shown in FIG. 4B, the grip 203 generally has a two-part structure. The grip 101 is fixed by sandwiching the switches 201 and 202 between the two grip parts 203a and 203b.
[0004]
[Problems to be solved by the invention]
In recent years, many electronic control devices have been mounted on hydraulic control devices such as power shovels. As a result, the number of switches required for the grip 203 has increased. In addition, with the diversification of products equipped with the joystick, various types or shapes of switches have been required.
[0005]
In the joystick 200 having the above-described conventional configuration, every time the number and shape of the switches provided in the grip 203 change, it is necessary to design and manufacture (mold) a grip component having a corresponding shape, resulting in an increase in cost.
[0006]
An object of this invention is to provide the joystick which can respond to a change of a specification more flexibly.
[0007]
[Means for Solving the Problems]
The joystick according to claim 1 is a joystick having a grip formed integrally and having a plurality of panels on the grip, and having a plurality of panels each having one or more switches. The panel is provided with an exchange means for removing the panel from the outside, and the back surface of the panel other than the panel equipped with the exchange means can be exchanged by removing the panel equipped with the exchange means. The panel is provided with an exchange means so as to face each other in the grip.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The joystick of the present invention is characterized in that one or more panels including one or more switches are provided in a replaceable state in the integrally formed grip portion. By adopting this configuration, various types of joysticks can be formed by simply replacing the panel without changing the shape of the grip.
Hereinafter, a joystick 100 according to an embodiment having the above features will be described with reference to the accompanying drawings.
[0011]
FIG. 1 is a perspective view of the joystick 100. The joystick 100 includes a grip 101 and a main body 104 that supports the grip 101 so that the grip 101 can be freely tilted in any direction. Like the conventional joystick, the main body 104 is provided with a mechanism for detecting a direction in which the grip 101 is tilted and outputting a control signal corresponding to the tilted direction to the cord 105.
[0012]
It should be noted that a well-known technique is adopted for the structure of the connecting portion between the grip 101 and the main body 104 and the mechanism for detecting the direction in which the grip 101 is tilted and outputting a corresponding control signal, and will be described here. Omit. This is because the joystick 100 of the present invention is characterized by the structure of the grip 101. For example, when applied to a hydraulic control device such as a power shovel, a hydraulic mechanism that discharges a predetermined pressurized fluid from a predetermined pipe corresponding to the direction in which the grip 101 is tilted is used instead of the control signal. May be.
[0013]
2A shows a front view of the grip 101, and FIG. 2B shows a rear view. The grip 101 includes a front panel 102 and a rear panel 103 that are replaceable. The front panel 102 includes two switches 102a and 102b. The rear panel 103 includes three switches 103a, 103b, and 103c. In this way, the switch can be modularized by adopting a configuration in which the switch is provided on the panel. The joystick 100 having the above-described configuration can be used for various devices only by changing the specifications of the panels 102 and 103 attached to the front and rear of the grip 101.
[0014]
The grip 101 employs, for example, a resin-made cylindrical integral formed by injection molding. By integrally forming the grip 101, the strength can be improved and the productivity can be improved by reducing the number of parts constituting the main body. The size and shape of the grip 101 may be variously changed depending on the application and function. Further, the shape of the lower portion of the grip 101 may be variously changed according to the structure of the connecting portion with the main body 104.
[0015]
FIG. 3 is a cross-sectional view of the grip 101. As a structure for waterproofing, the grip 101 includes a predetermined outer (skin) 101a on a base 101b. A structure is employed in which a seal lip structure is formed on the mating surface of the outer 101a with the base 101b for sealing. The front panel 102 is fixed to the base 101b by engaging a concave portion 102d provided at the upper end with the convex portion 101c of the base 101b and fastening the lower end portion with a set screw 102c. On the other hand, the rear panel 103 is locked to the base 101b by clips 105a and 105b. As shown in the drawing, by making the joining surfaces of the grip 101, the front panel 102, and the rear panel 103 into a planar shape, the moldability is improved and the sealing performance can be improved. Lines extending from the switches provided in the panels 102 and 103 are bundled with the cord 105.
[0016]
The front panel 102 can be removed by removing the set screw 102c. The rear panel 103 can be removed by picking the clips 105a and 105b from the opening formed by removing the front panel 102 . As described above, in the joystick 100, the panel can be easily replaced later. Thereby, the specification change of the joystick 100 can be easily performed without changing the shape of the grip 101.
[0017]
【The invention's effect】
In the joystick of the present invention, the grips are integrally formed, so that the number of joints can be reduced and the waterproofness can be improved. Further, since the number of components is reduced, productivity can be improved. Further, the panel can be easily replaced later, and the specification of the joystick can be easily changed.
