Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assist grip for a lever operating device in an order picker.

[0002]

2. Description of the Related Art As shown in FIG. 5, an order picker 1 has a pair of upright masts 2, a cab 3 is arranged behind the masts 2, and a vehicle runs in front of the masts 2. A functional product room 4 for accommodating a traveling drive device for carrying out the above and a cargo handling device for raising and lowering the cab 3 along the mast 2 is arranged. Further, the cab 3 is provided with a control unit 5 for operating traveling and ascending / descending, and the control unit 5 is provided with a steering handle 6, various instruments 7, and a lever operating device 8. FIG. 6 shows an enlarged view of the vicinity of the lever operating device 8 of the control unit 5. Lever operation device 8
Is equipped with a lifting lever 9 and a traveling lever 10.
The elevating lever 9 and the traveling lever 10 are provided so as to be tiltable back and forth. When the raising and lowering lever 9 is tilted, the driver's cab 3 moves up and down, and when the traveling lever 10 is tilted, the order picker 1 moves back and forth. Drive to. When the operator tilts the levers 9 and 10 in this manner, the order picker 1 performs an operation corresponding to the tilt. The tilted levers 9 and 10 automatically return to the neutral position when their hands are released, and the corresponding operation is stopped. Therefore, the elevating lever 9 or the traveling lever 10 must be always tilted while the elevating operation or the traveling operation is continued.

A U-shaped assist grip 11 is provided so as to surround the elevating lever 9 and the traveling lever 10. The assist grip 11 includes a right side portion 11a and a left side portion 11
b and an intermediate portion 11c, the operator operates the steering handle 6 with his left hand and grips the right side portion 11a of the assist grip with his right hand, while using some fingers of his right hand to raise and lower the lever 9 and travel. The lever 10 is operated. Further, in order to prevent a part of a worker's body or a load from accidentally coming into contact with the levers 9 and 10 and tilting during picking work or the like, an intermediate portion 11c of the assist grip 11 and the lift lever 9 and the traveling are prevented. The lever 10 is protected.

[0004]

However, during acceleration or deceleration of the travel of the order picker 1, the worker (driver) is often shaken back and forth. Therefore, the worker must support the body by holding the traveling lever 10 in a tilted state with some fingers of the right hand and holding the right side portion 11a of the assist grip 11 with the remaining fingers and palm of the right hand. . That is, since the body is supported by gripping the right side portion 11a provided parallel to the traveling direction of the order picker 1 with a part of the right hand, a large grip force is required, and there is a problem that the operator is easily tired. .

Therefore, it is an object of the present invention to provide an assist grip for a lever operating device of an order picker that easily supports the body of an operator even during acceleration / deceleration of traveling.

[0006]

In order to achieve the above object, the present invention relates to an assist grip provided in the vicinity of a lever operating device arranged on a driver's cab of an order picker, in the front and rear traveling directions. The first grip portion is provided in the vertical direction, and the second grip portion is provided in a direction perpendicular to the front-rear traveling direction and offset from the first grip portion in the front-rear direction.

[0007]

1 is a perspective view of an order picker having an assist grip according to an embodiment of the present invention. The order picker 12 has a pair of upright masts 13, a driver's cab 14 is arranged behind the masts 13, and a traveling drive device for driving the vehicle and a driver's cab 14 are provided in front of the masts 13. A functional goods room 15 for accommodating a cargo handling device and the like for raising and lowering along is arranged. Further, the driver's cab 14 is provided with a control unit 16 for operating traveling and ascending / descending, and the control unit 16 is provided with a steering handle 17, various instruments 18, and a lever operating device 19.

As shown in FIG. 2, the lever operating device 19 includes a lifting lever 20 and a traveling lever 21,
An assist grip 22 is provided so as to surround the lifting lever 20 and the traveling lever 21. The assist grip 22 is a forward grip part (first grip part).
22a, a reverse grip portion (second grip portion) 22b, and a hand rest portion 22c. Forward grip part 2
2a and the reverse grip part 22b are respectively provided in the vertical direction with respect to the front-back running direction of the order picker 12, and as shown in FIG. 3, the forward grip part 22a.
And the reverse Z together with the part that connects the reverse grip 22b.
It has a shape. In addition, a connecting portion that extends in the vehicle front-rear direction and connects the forward grip portion 22a and the reverse grip portion 22b, that is, a connecting portion from the bent portion at the right end of the reverse grip portion 22b to the bent portion at the left end of the forward grip 22a is formed. It is the hand rest portion 22c.

When the order picker 12 is moved forward, the operator uses the palm of the right hand and some fingers to move the forward grip portion 22a.
The body is supported by gripping and the running lever 21 is tilted and held forward by the remaining fingers. Also, when going backwards,
The operator supports the body by grasping the reverse grip portion 22b with the palm of the right hand and a part of the fingers, and appropriately tilts and holds the traveling lever 21 rearward with the remaining fingers (for example, the thumb). In this way, the forward grip portion 22a and the reverse grip portion 22b can be gripped in correspondence with the forward movement and the reverse movement, respectively, and these forward movement grip portion 22a and the reverse movement grip portion 22b can move in the front and rear traveling directions of the order picker 12. Since it is provided in the vertical direction, the worker can easily hold his / her body without requiring a large gripping force even during acceleration / deceleration of traveling. It should be noted that the body may be supported by gripping the reverse grip portion 22b when moving forward and holding the forward grip portion 22a when moving backward. The reverse grip portion 22b is the intermediate portion 11c of the conventional assist grip 11.
Similarly, during the picking work or the like, a part of the body of the worker or the load is prevented from inadvertently contacting the levers 20 and 2 and tilting. Further, since the lever operation can be performed while the palm is placed and fixed on the hand rest portion 22c, it is easy to finely operate the elevating lever 20 and the traveling lever 21. As described above, the hand rest portion 22
c is inclined with respect to the vehicle front-rear direction so that the entire assist grip has an inverted Z shape. Therefore, it is easier to support the operator's body as compared with the case of gripping a portion of the conventional U-shaped grip that extends parallel to the vehicle front-rear direction. In particular, the lifting lever 2 on the side away from the hand rest portion 22c
It is suitable for grasping the hand rest portion 22c when operating 0.

Further, since the assist grip 22 as described above is simply manufactured by only bending one pipe, it is economical. The manufacturing method and shape are not limited to those described above. For example, as shown in FIG. 4, the front side of the conventional U-shaped assist grip 23 is used as the reverse grip portion 23b and the traveling lever side is used. Alternatively, a member such as a pipe perpendicular to the traveling direction may be welded to form the forward grip portion 23a. In this case, the hand rest portion 23c extends from the right end of the reverse grip portion 23b to the left end of the forward grip portion 23a.

[0011]

As described above, according to the assist grip for the lever operating device of the order picker of the present invention,
Since the first grip portion and the second grip portion are provided in the vertical direction with respect to the traveling direction before and after the order picker, it is possible to easily hold the body of the operator even during acceleration / deceleration of traveling. .
