Joystick device
First Claim
1. A joystick device comprising:
- a case;
first and second bearing portions formed in said case to have respective axes extending perpendicular to each other;
a first rocking member having first support shafts supported by said first bearing portions, and a first elongate hole that extends in an axial direction of said first support shafts;
a second rocking member having second support shafts supported by said second bearing portions, and a second elongate hole that extends in an axial direction of said second support shaft, said first rocking member and said second rocking member being arranged in an overlapped state such that said first elongate hole and said second elongate hole extend perpendicular to each other and having a first flat portion and a second flat portion involved in a same plane;
a lever inserted through said first elongate hole and said second elongate hole, said lever when operated causing rocking movement in at least one of said first rocking member and said second rocking member, said lever including an engaging portion in engagement with one of said first rocking member and said second rocking member and a spherical portion formed at a position thereof above said second rocking member;
a detector operable to detect rocking movement in at least one of said first rocking member and said second rocking member to output an electric signal;
a cover attached to said case and having a hole defined by an inner peripheral edge that contacts with an outer peripheral surface of said spherical portion, said hole holding said spherical portion so that said lever can be operated in every direction; and
a spring provided within said case so as to return said lever to a neutral position by elastically repelling downward said first flat portion and said second portion in a constant manner.

Abstract
A joystick device includes a case so that first and second rocking members are respectively supported in a overlapped manner by first and second bearings formed in the case with their first and second elongate holes positioned perpendicular to each other. The operation of the lever inserted through the first and second elongate holes causes tilt movement in at least one of the rocking members so that the movement of the rocking member is supplied as a pulse signal by a detecting device. The lever includes an engaging portion engaged with the rocking member on the upper side, and a spherical portion formed at a position above the same rocking member. The cover has a hole having an inner peripheral edge with which an outer peripheral surface of the spherical portion is contacted so that the lever is operable in every direction. A spring is provided with the case, which acts to press down the rocking member thereby returning the lever to a neutral position.

14. A joystick device comprising:
-
an operating member to be tilt-operated by a hand; an initial-position returning mechanism arranged to be automatically returned to an initial position thereof when said operating member is released from an external force; a first interacting member arranged for interacting solely with movement in a first direction of said operating member; a second interacting member arranged for interacting solely with movement in a second direction perpendicular to the first direction of said operating member; a first displacing member having a gear portion in mesh with a gear portion formed in said first interacting member so as to be rotated based on movement of said first interacting member; a second displacing member having a gear portion in mesh with a gear portion formed in said second interacting member so as to be rotated based on movement of said second interacting member; a first sensor including a two channel, two phase detecting element for detecting an amount of displacement in said first displacing member to output a pulse; a second sensor including a two channel, two phase detecting element for detecting an amount of displacement in said second displacing member to output a pulse; a spherical portion formed at a portion of center of tilt movement in said operating member; a cover having a hole defined by an inner peripheral edge in contact with an outer peripheral surface of said spherical portion, said hole supporting said spherical portion so that said lever can be operated in every direction; and a rotation-preventive means provided at a contact position between said spherical portion and said inner peripheral edge of said hole to prevent said lever from rotating about an axis thereof.

15. A joystick device, comprising:
-
an operating member to be tilt-operated by a hand; an initial-position returning mechanism arranged to be automatically returned to an initial-position thereof when said operating member is released from an external force; a first interacting member arranged for interacting solely with movement in a first direction of said operating member, and having an elongate hole; a second interacting member arranged for interacting solely with movement in a second direction perpendicular to said first direction of said operating member, and having a second elongate hole extending in a direction perpendicular to a direction that said first elongate hole extends, said second interacting member being positioned below said first interacting member; and an engaging projection integrally formed in the vicinity of a lower end of said operating member to project along said second elongate hole to a length greater than a width of said first elongate hole, said engaging projection being slidable inside said second elongate hole and engaged with a bottom surface of said first interacting member to thereby prevent said operating member from being upwardly pulled off.

16. A joystick device comprising:
-
a case; first and second bearing portions formed in said case to have respective axes extending perpendicular to each other; a first rocking member having first support shafts supported by said first bearing portions, and a first elongate hole that extends in an axial direction of said first support shafts; a second rocking member having second support shafts supported by said second bearing portions, and a second elongate hole that extends in an axial direction of said second support shaft, said first rocking member and said second rocking member being arranged in an overlapped state such that said first elongate hole and said second elongate hole extend perpendicular to each other and having a first flat portion and a second flat portion involved in a same plane; a lever inserted through said first elongate hole and said second elongate hole, said lever when operated causing rocking movement in at least one of said first rocking member and said second rocking member, said lever including an engaging portion in engagement with one of said first rocking member and said second rocking member and a spherical portion formed at a position thereof above said second rocking member; a detector operable to detect rocking movement in at least one of said first rocking member and said second rocking member to output an electric signal; a cover attached to said case and having a hole defined by an inner peripheral edge that contacts with an outer peripheral surface of said spherical portion, said hole holding said spherical portion so that said lever can be operated in every direction; and a spring provided within said case so as to return said lever to a neutral position by elastically repelling downward said first flat portion and said second portion in a constant manner; said joystick device further comprising a pressing down member disposed between a lower end of said spring and said first and second flat surfaces to have a horizontal surface when said lever is at the neutral position, the repellent force of said spring being transmitted through said press-down member to said first and second flat planes.
