However, these conventional arrangements have the following problems. That is, in the former case, since the switch box 13 is disposed so as to overlap the upper surface of the meter panel 12, a part of the meter panel 12 becomes a shadow of the switch box 13 as shown in FIG. There was a problem that it was difficult for the driver to see.

In the latter case, the meter panel 2
Although the visibility of No. 2 is ensured well, since it is disposed in front of the switch box 23, there is a problem that the front view is narrowed as shown in FIG.

Thus, conventionally, the shift levers 10, 1
Since the operability of 1 (or 20, 21) was emphasized,
The visibility of the instrument panel or the visibility ahead was sacrificed.

SUMMARY OF THE INVENTION The present invention has been made in view of this problem, and is intended to provide an industrial vehicle that can ensure the visibility of a meter panel and the field of view ahead without impairing the operability of a shift lever. An object of the present invention is to provide an arrangement structure of a shift lever.

[0010]

According to the first aspect of the present invention, there is provided:
The arrangement of the shift lever, with the handle is attached to the upper end, on the left side of the steering post below said handle instrument panel mounted, a shift lever for shifting the shift lever for forward-reverse switching Are supported to be tiltable in the front-rear direction, and when both shift levers are shifted to select a front end or rear end shift position among the respective shift positions, the two shift levers have the same inclination angle with each other. A switch box in which each shift position is arranged is arranged independently of the steering post, the two shift levers protrude from the upper surface of the switch box in parallel left and right, and an intermediate portion curves toward the steering post. is the shape, the left end portion directly below the smell of the tip of each said handle Vertically disposed in parallel are respectively knob portion, both said knob portion is your hand in front Symbol handle
In a state where both shift levers are simultaneously operable, the shift levers are independently operated between the handle and the knob near the handle and between the knobs. The two shift levers are arranged so that a sufficient interval is ensured in the vertical direction .

[0011]

According to the above construction, the switch box on which the shift lever is supported is arranged independently of the steering post, so that the visibility of the meter panel attached to the steering post is impaired by the switch box. Never.

Further, since the switch box is not attached to the steering post, it is not necessary to shift the installation position forward in order to secure the visibility of the instrument panel as in the prior art. , Both of which can be favorably secured.

Conventionally, the switch box is mounted on the steering post in order to ensure good operability of the shift lever. However, both shift levers protrude upward from the upper surface of the switch box and each of the shift levers is mounted on the steering post. The front end is curved toward the steering post, each knob is located in a range that allows both shift levers to be operated simultaneously with the handle, and both shift levers are operated independently between both knobs With sufficient spacing, the operability of both shift levers is still well maintained, and the switch box is not located on the steering post as in the past, but is located independently on the left side of it. Doing so does not impair the operability.

[0014]

Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the meter panel 2
Is mounted on the steering post 1 so that the meter panel 2 does not impair the view obliquely downward and forward.

A front protector 7 is mounted in front of the driver's cab and in front of the steering post 1. An upper portion of the front protector 7 is provided with a substantially horizontal pedestal 7a which is folded in a reverse L-shape toward the near side (driver side).

A parking brake lever 8 is arranged on the left side of the steering post 1 at a position where the driver can easily reach.

Between the steering post 1 and the lever 8 and on the upper surface of the pedestal 7a of the front protector 7, a shift lever 5 for forward / reverse switching and a shift lever 6 for speed switching are provided in the switch box 4. Are arranged through.

The shift levers 5 and 6 are independently supported by the switch box 4 so as to be swingable in the front-rear direction (the direction perpendicular to the plane of the drawing), and the swing center 9 is as shown in FIG. Is located on the same axis. As shown in the figure, a shift lever 5 for switching between forward and backward movement is disposed on a side closer to the steering post 1, and a shift lever 6 for switching speed is disposed on a far side.

As shown in FIG. 4, the forward position F, the neutral position N, and the reverse position R are switched by a shift lever 5 for forward / reverse switching, and the first speed is switched by a shift lever 6 for speed switching. And a second speed shift is performed.

The shift lever 5 is shifted to a forward position F, which is a front end (upper end in the figure, the same applies hereinafter), and the shift lever 6 is shifted to a first speed, which is a front end shift position. Is shifted to the reverse position R, which is the rear end (lower end, hereinafter the same) shift position, and if the shift lever 6 is shifted to the second speed, which is also the rear end shift position, the inclination of both shift levers 5, 6 The angles are matched as shown in FIG. 3, and the respective positions are arranged so that the swing ranges of both shift levers 5 and 6 are the same.

The two shift levers 5, arranged in this manner,
Numeral 6 is drawn upward from two long groove holes 4a, 4a formed at predetermined intervals (dimension A in FIG. 2) parallel to each other on the upper surface of the switch box 4, and is curved toward the steering post 1 side. The handle 3 is formed so that each tip side is substantially vertically parallel immediately below the left end of the handle 3. The horizontal portions of the two shift levers 5 and 6 serve as knobs 5a and 6a, respectively.

The distance between the knobs 5a and 6a (FIG. 2)
Medium, B) is a distance that is small enough for the driver to grasp both knobs 5a, 6a at a time with one hand (left hand), and that the driver needs to hold both knobs 5a, 6a independently. So that the distance is large enough to insert
The length or the curved shape of the two shift levers 5 and 6 are adjusted.

The two knobs 5a, 6a are
In order for the driver to be able to operate both shift levers 5 and 6 with their hands attached to the steering wheel, a distance sufficiently close to the steering wheel 3 (the distance between the steering wheel 3 and the knob portion 5a (C in FIG. 2)
(Dimension) is about 70 mm at the maximum).

This embodiment is constructed as described above.
According to this configuration, the following operation and effect can be obtained. That is, since the switch box 4 on which the shift levers 5 and 6 are supported is arranged independently of the steering post 1, the visibility of the meter panel 2 attached to the steering post 1 is controlled by the switch box 4. It will not be compromised.

Further, since the switch box 4 is not attached to the steering post 1, it is not necessary to shift the installation position forward in order to secure the visibility of the meter panel 2 as in the prior art. Both visibility and the field of view ahead can be ensured satisfactorily.

Here, conventionally, the shift levers 10, 11
Although the switch box 13 (or 23) is attached to the steering post 14 (or 24) in order to ensure the good operability of (or 20, 21), according to the arrangement structure of this example, both shifts are provided. Lever 5, 6
Each of the knobs 5a, 6a protrudes upward from the upper surface of the switch box 4 and is curved toward the steering post 1 so that the respective knobs 5a, 6a reach just below the left end of the handlebar 3 so that the two shift levers 5, 6 are connected to the handlebar 3, respectively. At the same time, the driver can use the steering wheel 3
The shift lever 5 or 6 can be operated simultaneously or independently with the hand (left hand) attached to the
Conventional good operability is secured as it is.

When the shift levers 5, 6 are shifted to the front end (forward position F, first speed position) or the rear end (reverse position R, second speed position), the inclination angle of both shift levers 5, 6 is set. In this shift position, the driver holds his hand on the steering wheel 3 and places his / her fingertip on both the knobs 5a and 6a to shift the two shift levers 5 and 6 simultaneously. You can also do it.

Further, a sufficient interval (dimensions C and B) is provided between the handle 3 and the knob 5a and between the knobs 5a and 6a so that the driver can insert his / her hands. The shift lever 5 or 6 can be operated alone.

As described above, according to the arrangement structure of the present embodiment, the operability of both shift levers 5 and 6 is still as good as before, while the visibility of the meter panel 2 and the front view are well assured. Will be able to do it.

[0030]

According to the present invention, the switch box in which the shift lever for forward / reverse switching and the shift lever for speed switching is supported is not a steering post as in the prior art.
It is located on the left side of this steering post, and both shift levers are configured with knobs so that the driver can operate simultaneously while holding the hand on the steering wheel. All of the visibility and the operability of both shift levers can be ensured in a favorable manner.
