Abstract
A manipulator mechanism includes a rotary shaft rotatable about an axis extending in a first horizontal direction, an operation member disposed at one of opposite ends of the rotary shaft in an axial direction thereof to rotate together with the rotary shaft, an angle sensor disposed at the other of the opposite ends of the rotary shaft in the axial direction to detect a rotation angle of the rotary shaft, and a neutral return mechanism provided between the operation member and the angle sensor to return the operation member to a neutral position from a post-operation position which is a position to which the operation member has been moved.
Claims17
A manipulator mechanism comprising:
- a rotary shaft rotatable about an axis extending in a first horizontal direction;
- an operation member disposed at one of opposite ends of the rotary shaft in an axial direction thereof to rotate together with the rotary shaft;
- an angle sensor disposed at the other of the opposite ends of the rotary shaft in the axial direction to detect a rotation angle of the rotary shaft;
- and
- a neutral return mechanism provided between the operation member and the angle sensor to return the operation member to a neutral position from a post-operation position, the post-operation position being a position to which the operation member has been moved, wherein
- the neutral return mechanism includes
- an interlock shaft disposed higher than the rotary shaft and extending in a second horizontal direction intersecting the first horizontal direction,
- an interlock arm to which one of opposite ends of the interlock shaft is pivotally supported and connected, the interlock arm being provided on the rotary shaft such that the interlock arm protrudes upward from the rotary shaft, and
- a neutral return spring including a coil spring fitted on the other of the opposite ends of the interlock shaft to bias the interlock shaft to return the operation member to the neutral position.
A working machine comprising:
- a machine body;
- an operator's seat on the machine body;
- a manipulator base provided forward of the operator's seat;
- an operation member swingable and disposed at the manipulator base;
- and
- an operation supporting mechanism to support the operation member, wherein
- the manipulator base includes an armrest having an upper portion and a lower portion that form a hollow portion therebetween, and the armrest extends in a rearward direction away from the manipulator base to reach an area at one side of the operator's seat, and
- the operation supporting mechanism includes a neutral return mechanism to return the operation member to a neutral position from a post-operation position and a swing restricting mechanism to limit an operation amount of the operation member from the neutral position, and is contained inside the hollow portion of the armrest, the post-operation position being a position to which the operation member has been moved.
A working machine comprising:
- a machine body;
- an operator's seat on the machine body;
- and
- a manipulator base provided forward of the operator's seat on the machine body and having attached thereto a manipulator member to be held and operated, wherein
- the manipulator base includes a flip-up armrest extending in a rearward direction away from the manipulator base,
- the flip-up armrest is
- configured to be switchable between a first orientation that does not allow an operator to sit on or get off the operator's seat and a second orientation that allows the operator to sit on and get off the operator's seat, and
- configured such that, when the flip-up armrest is in the first orientation, an actuation of an operation object to be operated by the manipulator member is allowed, and, when the flip-up armrest is in the second orientation, the actuation of the operation object is not allowed.
