Abstract

PURPOSE: To provide an easy operating property which can be operated by light force with a finger tip, by providing an arm rest tiltable near the seat on the vehicle body of a forklift, and a joy stick at the front end of the arm rest. CONSTITUTION: An arm rest 6 is fixed to the upper end of an arm bracket 5 projecting horizontally. A joy stick 15 is installed to an inclined surface at the front end of the arm rest 6, while a forward and rearward changeover switch 16, a direction instruction switch 17, a hone switch 18, and the like are installed on the wall surface. Consequently, when a driver rides on, the arm rest 6 is inclined together with the arm bracket 5, to the seat back side of the driver seat, making a pipe 12 as the center, and after the driver sits on the seat, the arm rest 6 is inclined in the reverse direction from the sitting time, and the forklift can be operated by operating the joy stick 15 and the like with fingers. Since the joy stick 15 and the seat are made in a unitary structure, the joy stick 15 can be operated with no trouble even though vibration is generated to the body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device for hydraulic operation of a forklift, which is a device such as a joystick that can be operated with a light force of a fingertip and is intended to facilitate operability.

[0002]

2. Description of the Related Art Conventionally, in a forklift, particularly a counterbalance forklift, a joystick is fixed to an engine hood or a battery cover on the vehicle body.

[0003]

As described above, since the joystick is conventionally fixed to the engine hood or the battery cover on the vehicle body, the driver holds the arm when operating the joystick. There is nothing. Therefore, it is necessary to continue to operate the joystick while keeping his / her arm at a constant angle, which is a long work and a pain. In addition, in many cases, a suspension mechanism is built in between the seat and the vehicle body to improve the riding comfort, and only the seat moves up and down relatively due to the vibration of the vehicle body. The problem that the operation of the stick becomes difficult occurs. The present invention has been devised to solve the above problems.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an armrest is provided in the vicinity of a seat on a vehicle body of a forklift in a tiltable manner, and a joystick is arranged at a front end portion of the armrest. Is.

[0005]

According to the present invention, when the driver gets in the vehicle, his / her arm is placed on the upper surface of the armrest and the joystick or the like is operated only by a finger to hydraulically operate the forklift.

[0006]

Embodiments of the present invention will be described with reference to FIGS. FIG. 1 is a side view showing a case in which the present invention is specifically applied to a forklift, and reference numeral 1 is a forklift, and in this embodiment, a battery type counterbalance forklift will be described. Reference numeral 2 is a vehicle body of the forklift 1, 3 is a battery cover for covering a battery (not shown) housed in the vehicle body 2, 4 is a seat mounted on the battery cover 3, and the seat 4 is a seat portion. 7 and back part 8,
It is mounted on the battery cover 3 via the mounting seat 9.

The seat 4 is composed of a stool portion 7 and a backrest portion 8. The stool portion 7 and the backrest portion 8 are connected by a substantially L-shaped frame pipe member 11, and the L-shaped bent portion 1 is formed.
1A, a pipe 12 for tiltably supporting an arm bracket 5 to be described later is attached to a U-shaped bolt 13 and a mounting plate 2.
It sticks with 5.

A pipe 12 is pierced through the lower end of the arm bracket 5, and an armrest 6 is fixed to the upper end of the arm bracket 5 so as to project in the horizontal direction.

The front end of the armrest 6 is a box-shaped body having a wide plane and an inclined surface on the side. The joystick 15 is provided on the inclined surface, and the forward / reverse selector switch 16 is provided on the side wall in the direction. Instruction switch 17, horn switch 1
8 and the emergency stop switch 19 are installed individually.

[0010]

As described above, according to the present invention, when the driver gets in the vehicle, the armrest 6 and the arm bracket 5 are tilted toward the backrest 8 side of the seat 4 with the pipe 12 as the center of rotation so that the driver can be seated on the seat 4. After sitting, the armrest 6 together with the arm bracket 5 is tilted in the direction opposite to the above with the pipe 12 as the center of rotation, the arm is placed on the upper surface of the armrest, and the forklift can be operated by operating the joystick 15 and the like only with fingers. Even if the vehicle body 2 vibrates, even if the vehicle body vibrates, the joystick 15 and the seat 4 have an integrated structure. The operation of the joystick 15 does not cause any trouble.
