Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an assist grip for supporting an armrest and a body of a reach type forklift.

[0002]

2. Description of the Related Art FIG. 17 is a perspective view showing an appearance of a reach type forklift 1. As shown in FIG. The control panel 2 is provided with an accelerator lever 3 for performing forward, backward and speed control, a cargo handling lever group 5 for performing each operation of reach, lift and tilt of the fork 4, and a steering handle 6. The driver stands up on the floor 7 and performs a driving operation. At the time of forward start, forward acceleration, or sudden braking of reverse, the body is likely to be thrown out of the rear elevating opening 8 by inertia. In order to prevent this, an assist grip 100 is provided near the accelerator lever 3, and in such a case, the driver holds the assist grip 100 to support the body.

FIG. 18 shows a conventional reach-type forklift 1.
FIG. 3 is a perspective view of a control panel 2 having the assist grip 100 of the first example. An accelerator lever 3 is provided on the control panel 2, and a cargo handling lever group 5 is provided on the left side thereof. A lever grip 3a is attached to the tip of the accelerator lever 3. An armrest 11 is fixed near the right side of the accelerator lever 3, and an assist grip 100 is fixed in front of the armrest 11. The assist grip 100 is a U-shaped bar-shaped steel product, and includes a horizontal grip portion 101 and rising portions 102 at both left and right ends. When the driver performs the driving operation, FIG.
As shown in FIG. 9, the right arm is placed on the armrest 11, and the accelerator lever 3 is operated while holding the body by holding the grip portion 101 with the right hand. FIG. 19 shows a forward operation, and the driver pushes the lever grip 3a of the accelerator lever 3 forward with his thumb to perform the forward operation. The left hand (not shown) operates the handle 6.

FIG. 20 shows a conventional reach-type forklift 1.
It is a perspective view of control panel 2 which has assist grip 100a of the 2nd example. The same members as those in the first example are denoted by the same reference numerals, and description thereof will be omitted. A recess 11b is provided at a lower portion of the front end of the armrest 11a.
00a. During the driving operation, the driver places the right arm on the armrest 11a as shown in FIG. 21, puts the fingertip of the right hand into the recess 11b of the armrest 11a, and operates the accelerator lever 3 with the thumb while supporting the body.

[0005]

However, the above configuration has the following problems. (1) In the first example, as shown in FIG. 19, the rising portion 102 of the assist grip 100 is in the way, and the gripping position is restricted, which adversely affects operability. In particular, when the right hand is moved between the accelerator lever 3 and the cargo handling lever group 5, the rising portion 102 becomes an obstacle. In addition, since the assist grip 100 is a bar-shaped steel product, it is difficult to grip and gives a driver discomfort in winter. (2) In the second example, since the fingertip of the right hand is merely inserted into the recess 11b of the armrest 11a, the body is held only by the force of the fingertip, and the driver is tired.

An object of the present invention is to provide an assist grip for a reach-type forklift which has good operability, is easy to grasp, and reduces driver fatigue, focusing on the above problems.

[0007]

In order to achieve the above object, a first invention of an assist grip for a reach-type forklift according to the present invention is directed to an assist grip that a driver grips to support a body. In a reach-type forklift equipped with a grip near the accelerator lever on the control panel, the assist grip has a height equal to or less than the accelerator lever lever grip.
It has a rod-shaped grip portion projecting to the lever grip side in a substantially horizontal direction.

According to the above configuration, there is no rising portion on the accelerator lever side of the assist grip, and the driver can grip an arbitrary position of the assist grip. In addition, since the grip portion of the assist grip has a height equal to or less than the lever grip of the accelerator lever, the operability of the accelerator lever with the thumb while holding the assist grip is good. Further, when the right hand is moved between the accelerator lever and the cargo handling lever group, there is no obstacle, and the workability is good.

According to a second aspect based on the first aspect, the assist grip has a position adjusting means for selecting a relative position with respect to the accelerator lever.

According to the above configuration, the driver can adjust the position of the assist grip to an optimal position for operating the accelerator lever with the thumb while holding the assist grip, thereby improving operability. Fatigue can be reduced.

According to a third aspect of the present invention, there is provided a reach-type forklift provided with an assist grip and an armrest which a driver grips to support a body, wherein the assist grip is integrally formed with the armrest and a lever grip of an accelerator lever. It is configured to have a rod-shaped grip portion that is equal to or less than the height and that protrudes in the substantially horizontal direction toward the lever grip.

According to the above configuration, the assist grip has no raised portion on the accelerator lever side and the height is equal to or less than the lever grip of the accelerator lever, so that the thumb can be operated while the assist grip is gripped. The properties are good. In addition, since the assist grip is integrally formed with the armrest, the number of parts is reduced, and assemblability is improved.

According to a fourth aspect based on the third aspect, the assist grip has a position adjusting means for selecting a relative position with the armrest and selecting a relative position with the accelerator lever integrally with the armrest. I have.

According to the above structure, the driver can adjust the relative position between the armrest and the assist grip to an optimum position, thereby reducing fatigue and optimizing the relative position between the accelerator lever and the assist grip. Thereby, the operability is improved.

A fifth invention is based on the first to fourth inventions, wherein the grip portion of the assist grip has a surface made of an elastic body.

According to the above configuration, since the grip portion is an elastic body, it is easy to grasp, and there is no discomfort even in winter. In addition, since the stability of the driver's body can be reliably maintained, work can be performed safely, and fatigue can be reduced.
