Abstract

PROBLEM TO BE SOLVED: To facilitate to operate a fork lift safely and efficiently for a long time similarly as an ordinary worker even in the case of a very tall worker by constructing both an elbow protector and a waist protector so as to be movable upward. SOLUTION: A waist protector has such a construction as a fixing bolt is slightly loosened, and the waist protector 6 is vertically moved to vertically move a slot near its middle along the fixing bolt, and then it is fastened at a proper height suiting to the stature of the worker for fixing the waist protector. In the case of the elbow protector base 9, a fixing bolt 9A is slightly loosened to vertically move a slot near the middle of the front and rear faces of the elbow protector 9 along the fixing bolt 9A, and the fixing bolt 9A is fastened at a proper height suiting to the stature of the worker for fixing the elbow protector. The elbow protector 8 installed on an elbow protector base 9 is also vertically movable, and can therefore be fixed at the height suiting to the stature of the worker. Thus, the very tall worker can operate and work at the operating posture the same as that of a usual stature worker.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents a worker of high height from bending over when operating an operation device of a reach type forklift truck, and safely and efficiently in the same correct driving posture as a worker of general height. The present invention relates to a forklift operation device that enables good work to be performed.

[0002]

2. Description of the Related Art For example, in a conventional reach type forklift, when a worker with a high height is driving, only the waist rest of the operator's cab is moved upward by using slide rails or bolts arranged on the back of the hip rest. I was driving.

[0003]

When operating a reach type forklift, the waist and elbow pads of the driver's cab and the cab of the driver's cab are usually applied to stabilize the operator's body. . Therefore, as described above, in the structure in which only the waist rest of the operator's cab moves upward, a worker with a high height must support his / her body only with his / her waist, which makes the body unstable compared to a worker with a normal height. I had to work in this condition.

The reach type forklift that operates in a standing state has a structure in which a difference in height appears significantly during operation, unlike the counterbalance type forklift that operates in a sitting state.

Then, in order to solve this unstable state even a little, the worker continues to drive in a bent state. Therefore, it caused backache when the driver had to continue driving for a long time. Further, due to the unstable state or the bent state, the work efficiency was naturally deteriorated.

In order to solve such a problem, the inventor moves not only the waist rest but also the elbow rest upward at the same time, and stabilizes the body by using the elbow rest like a worker of general height. The present invention that can be realized was devised and completed.

An object of the present invention is to provide an operating device for a forklift truck, which enables safe and efficient long-time operation work even when a reach-type forklift operator has a high height, like a worker of normal height.

SUMMARY OF THE INVENTION The present invention comprises a vehicle body and a mast for vertically moving a load in front of the vehicle body. The vehicle body has an operation console provided on a driver's cab on a central upper surface and an arm for operating a forklift. A reach-type forklift having an elbow rest supporting the armrest and a waist rest supporting the body in the rear cab, wherein the elbow rest is moved upward.

In addition to the above, the forklift operating device may be characterized in that the elbow rest is moved upward together with the waist rest, or the operating console is also moved upward.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention in which only the elbow rest 8 moves upward will be described below as an example of an embodiment of the present invention with reference to the drawings.
1 to 6, a reach type forklift 1 comprises a vehicle body 2, a cargo handling device 3 in front of the vehicle body 2, a driver's cab 4 behind the vehicle body 2, and a driver's cab 5 on the central upper surface of the vehicle body 2.

A conventional waist support 6 is fixed to the inside of the operator's cab 4 by two fixing bolts. To move the waist pad 6 up and down, loosen the fixing bolt a little and move the waist pad 6 up and down to move the elongated hole near the center of the waist pad 6 up and down along the fixing bolt.
It is a structure that can be fixed by tightening the fixing bolt at an appropriate height according to the height of the worker.

An operation console 7 and an elbow pad 8 are installed on the upper surface of the cab 5. The operation platform 7 of the reach type forklift 1 usually includes several valve levers 7A for operating the cargo handling device 3 such as a lift lever, a reach lever, and a tilt lever.
Switches such as a traveling lever 7B for instructing the forward and backward direction and speed to move the vehicle body 2, a display for displaying the state of the vehicle body 2, and other headlights are arranged on the panel.

The elbow pad 8 which is a feature of this embodiment is an operating table 7.
It is installed on the right side, and when driving the vehicle body 2, the right elbow supporting the weight is placed, and the valve lever 7A, the traveling lever 7B and the like can be operated.

In the present embodiment, the armrest 8 is formed so as to cover the upper surface to the rear surface of the driver's cab 5 as shown in each figure, and is installed on the elbow rest 9 embedded in the driver's cab 5. The elbow rest 9 has two fixing bolts 9 near the center of the front and the rear.
A long hole 9B having a size through which A passes is installed, a fixing bolt 9A is inserted from the outside of the elbow rest 9, and is fixed by a screw hole portion 9C installed on a plate material fixed to the vehicle body 2.

In this elbow rest 9, when the fixing bolt 9A is loosened a little and the elbow rest 9 is moved up and down, the elongated hole 9B near the center of the front and rear surface of the elbow rest 9 moves up and down along the fixing bolt 9A. It is a structure that can be fixed by tightening the fixing bolt 9A at an appropriate height according to the person's height. When the elbow rest 9 moves up and down, the elbow rest 8 installed on the elbow rest 9 naturally moves up and down, so that the elbow rest 8 can be fixed at a height according to the height of the worker.

A worker of a high height having the above-mentioned structure adjusts the elbow pad 9 from the normal driving posture as shown in FIG. 2 and is the same as a general worker having a height as shown in FIG. You can drive and work in this driving posture.

Other than the above, the elbow pad 8 has the same structure as the above.
There are various combinations such as a structure in which the control pad 7 and the operation pad 7 are simultaneously moved up and down, an elbow pad 8 and a hip pad 6 are integrated, or an elbow pad 8, the operation pad 7 and the hip pad 6 are integrated. Conceivable.

Regarding the method of moving the elbow pad 8 up and down, adjustment of the fixing bolt 9A and the elongated hole 9B, which seems to be the simplest structure in this embodiment, was used, but various other methods are possible. . For example, the use of slide rails simplifies the adjustment work, and is effective in the case of a forklift used by multiple workers.

[0020]

As described above, the operating device for the reach type forklift according to the present invention is capable of working in the same posture as a worker of general height even if the worker is of high height by having the above-mentioned configuration. Become. An unstable posture such as a driving posture while bending down is eliminated, and the cause of back pain is eliminated. Therefore, it is possible to provide a forklift operation device capable of performing a safe and efficient forklift operation.
