Abstract

An operating mechanism of a work vehicle includes: an operating portion that is provided to a side console disposed beside a seat and can be operated by an operator; and a switching portion capable of switching between a used state in which the operating portion can be used and a non-used state in which the operating portion cannot be used.

First claim

What is claimed is:

1. An operating mechanism of a work vehicle comprising:
an operating portion that is provided to a console disposed beside a seat and can be operated by an operator;
a switching portion capable of switching between a used state in which the operating portion can be used and a non-used state in which the operating portion cannot be used,
a transmitting portion that transmits a motion to a predetermined device,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock,
switches to the used state by restricting rocking of the operating portion with respect to the transmitting portion and enabling the transmitting portion to move in conjunction with operation of the operating portion, and
switches to the non-used state by allowing the rocking of the operating portion with respect to the transmitting portion and rocking the operating portion to a predetermined position.

2. The operating mechanism of the work vehicle according to claim 1 ,
wherein the predetermined device
is a control valve that controls a motion of a front loader.

3. The operating mechanism of the work vehicle according to claim 2 ,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock forward and backward.

4. The operating mechanism of the work vehicle according to claim 2 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second member with respect to the first member by being fitted over the first member and the second member in a state in which the second member rocks to a predetermined position with respect to the first member.

5. The operating mechanism of the work vehicle according to claim 3 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second member with respect to the first member by being fitted over the first member and the second member in a state in which the second member rocks to a predetermined position with respect to the first member.

6. The operating mechanism of the work vehicle according to claim 1 ,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock forward and backward.

7. The operating mechanism of the work vehicle according to claim 6 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second member with respect to the first member by being fitted over the first member and the second member in a state in which the second member rocks to a predetermined position with respect to the first member.

8. The operating mechanism of the work vehicle according to claim 1 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second member with respect to the first member by being fitted over the first member and the second member in a state in which the second member rocks to a predetermined position with respect to the first member.

9. The operating mechanism of the work vehicle according to claim 8 ,
wherein the restricting member
is provided to one of the first member and the second member to be able to slide in such a direction as to move toward and away from the other of the first member and the second member.

10. The operating mechanism of the work vehicle according to claim 9 ,
wherein the switching portion further includes
a biasing member that biases the restricting member toward the other of the first member and the second member.

11. The operating mechanism of the work vehicle according to claim 8 , further comprising
a cover portion that covers the restricting member,
wherein the switching portion further includes
a restriction operating portion that can operate the restricting member from outside the cover portion.

12. An operating mechanism of a work vehicle comprising:
an operating portion that is provided to a console disposed beside a seat and can be operated by an operator;
a switching portion capable of switching between a used state in which the operating portion can be used and a non-used state in which the operating portion cannot be used, wherein the switching portion switches from the used state to the non-used state by folding the operating portion,
a transmitting portion that transmits a motion to a predetermined device,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock,
switches to the used state by restricting rocking of the operating portion with respect to the transmitting portion and enabling the transmitting portion to move in conjunction with operation of the operating portion, and
switches to the non-used state by allowing the rocking of the operating portion with respect to the transmitting portion and rocking the operating portion to a predetermined position.

13. The operating mechanism of the work vehicle according to claim 12 ,
wherein the predetermined device
is a control valve that controls a motion of a front loader.

14. The operating mechanism of the work vehicle according to claim 13 ,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock forward and backward.

15. The operating mechanism of the work vehicle according to claim 13 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second member with respect to the first member by being fitted over the first member and the second member in a state in which the second member rocks to a predetermined position with respect to the first member.

16. The operating mechanism of the work vehicle according to claim 12 ,
wherein the switching portion
couples the operating portion to the transmitting portion such that the operating portion can rock forward and backward.

17. The operating mechanism of the work vehicle according to claim 16 ,
wherein the switching portion includes
a first member fixed to the transmitting portion,
a second member fixed to the operating portion,
a coupling portion that couples the first member and the second member such that the first member and the second member can rock, and
a restricting member that can restrict rocking of the second me
