A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and an operation device provided on at least one of a left side portion and a right side portion of the seat. The operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface. At least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above.

First claim

The invention claimed is:

1 . A vehicle, comprising:
a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and an operation device provided on at least one of a left side portion and a right side portion of the seat, wherein the operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface, at least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above, the lever is supported on the seat to be pivotable about a rear end thereof between an initial position in which the lever extends substantially horizontally and an operation position in which the lever is inclined upward in the forward direction, and the operation panel includes a lever support that supports a tip of the lever positioned in the initial position from below.

2 . The vehicle according to claim 1 , wherein the seat includes a pad configured to contact the buttocks of the user,
left and right side portions of a front portion of the pad are inclined laterally inward in a forward direction as seen from above, and a distance between a front end portion of the lever and the pad in a lateral direction is greater than a distance between a rear end portion of the lever and the pad in the lateral direction.

3 . The vehicle according to claim 2 , wherein the pad includes a pair of left and right bank parts on left and right side portions thereof, the bank parts protruding upward, and
the operation surface is disposed lower than upper edges of the bank parts.

4 . The vehicle according to claim 3 , wherein the lever in the initial position is disposed at a same height as the upper edges of the bank parts.

5 . The vehicle according to claim 2 , wherein at least one of the multiple operation members is a joystick for operating the drive unit and is disposed between the front end portion of the lever and the pad as seen from above.

6 . The vehicle according to claim 1 , wherein the operation device includes a pair of left and right operation devices respectively provided on the left side portion and the right side portion of the seat.

7 . The vehicle according to claim 6 , wherein left and right knee belts for restraining knees of the user extend from front portions of the operation panels of the left and right operation devices, respectively.

8 . The vehicle according to claim 1 , wherein at least one of the multiple operation members is configured to be lighted.

9 . A vehicle, comprising:
a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; an operation device provided on at least one of a left side portion and a right side portion of the seat; at least one first leg extending downward from the seat and provided with a roller at a lower end thereof; and at least one second leg extending downward from the seat, provided with a contact member at a lower end thereof, and displaceable in an up-down direction, wherein the operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface, and at least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above, the lever is connected to the at least one second leg via a transmission mechanism, when the seat is in the high position, the roller and the contact member are separated from the floor surface, when the seat is in the low position, the roller and the contact member are capable of contacting the floor surface, and when the seat is in the low position, the contact member is separated from the floor surface according to an operation of the lever.

10 . A vehicle, comprising:
a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and an operation device provided on at least one of a left side portion and a right side portion of the seat, wherein the operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface, and at least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above, wherein the operation panel includes a recess that is recessed downward from the operation surface below the lever, and at least one of the multiple operation members is disposed in a bottom portion of the recess.
