Abstract

PURPOSE: To surely recognize the direction of a steering wheel regardless of the height of elevation of a driver's cab by equipping an indicator panel part with steering indicators consisting of LED's which show the direction of steering wheels, being arranged radially, in a vehicle being equipped with a driver's cab moving up and down together with a fork. CONSTITUTION: An order picking car has a driver's cab moving along a mast erected at the rear of the car body, and a pair of forks are fixed to the bottom of the driver's cab. At the indicator panel 5 installed at the front wall of the driver's cab are a steering indicator 6, an operation indication lamp 7, a stop indication lamp 8, a battery's residual quantity meter 9, a key switch 10, and an emergency stop button 11 arranged. This steering indicator 6 lights, according to the steering angle detected by the potentiometer installed at the steering wheel. It is composed of a LED's.A arranged in radial shape and LED's.B being lit with different luminous lights only when the steering wheels are in straight drive direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering indicator for an order-picking vehicle, which enables a driver to recognize the direction of steered wheels regardless of the rising height of a driver's cab.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, in an order-picking vehicle including a driver's cab that moves up and down along with a fork that moves up and down along a mast standing upright at the rear of the vehicle, a steering indicator is provided on the upper surface of the vehicle as steering wheels. It was installed so as to indicate the direction of the steered wheels coaxially.

[0003]

In the above-mentioned prior art, when the driver's cab is at the bottom, the steering indicator can be checked and there is no problem. However, when the driver's cab is at the top, the driver's cab and mast are not. Made it difficult to check the steering indicator. Therefore, in this case, it is necessary to travel only with the driver's intuition, and an unfamiliar driver travels without knowing in which direction the vehicle is going. In addition, it is difficult for a skilled person to judge the steering angle. As a countermeasure against this, in the conventional technology, the direction of the steered wheels was checked by starting the vehicle only slightly at low speed, but it is not known in which direction the vehicle will travel when the vehicle starts, and it takes longer work. Was also the cause.

[0004]

SUMMARY OF THE INVENTION The present invention provides a steering indicator for indicating the direction of steered wheels in an order-picking vehicle including a driver's cab that moves up and down along with a fork that moves up and down along a mast that is erected on the rear side of a vehicle body. To
The above problem is solved as a structure of a stelling indicator of an order picking vehicle, which is provided in an indicator panel portion installed on a front wall of the cab.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an order-picking vehicle embodying the present invention. Reference numeral 1 is a vehicle body of the order-picking vehicle, and steering wheels are provided in front of a lower portion of the vehicle body 1 (not shown). 2 is a mast standing upright at the rear of the vehicle body 3, 3 is a driver's cab that moves up and down along the mast 2, 4 is a pair of forks fixed to the lower surface of the driver's cab 5, and 5 is an indicator installed on the driver's front wall panel,
From the left side of the indicator panel 5, a steering indicator 6, a driving display lamp 7, a stop display lamp 8, a battery fuel gauge 9, a key switch 10, an emergency stop button 1
1 is arranged.

According to the present invention, the steering angle is detected by the potentiometer installed on the steered wheels, and the LE is displayed on the steering indicator 6 through the wiring of the mast portion according to the steering angle.
The structure is such that D and A are displayed. Further, the LEDs A are arranged at a constant angle radially from the center.

Further, in this embodiment, the LEDs, B of the steering indicator have a structure in which the luminescent color can be changed at a glance to recognize that the steered wheels are in the straight ahead position only when the steered wheels are in the straight ahead direction.

[0008]

According to the present invention, with the above-described structure, since the steering indicator is located in front of the driver of the driver's cab, the driver can confirm the steering indicator regardless of the raised position of the driver's cab. It is in a position where it can be surely done, and the direction of the steered wheels can be judged regardless of familiarity and unfamiliarity, and the traveling direction at the time of starting can be surely known.
