Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates primarily to cargo handling vehicles, and more particularly to improvements in seat bar-equipped vehicles equipped with seat bars to ensure operator safety.

(Prior Art) Conventionally, as this type of seat bar equipped vehicle 20, for example, a skid steer loader shown in FIGS. 3 and 4 is known.

This is a tire-type cargo handling vehicle using a fluid pressure drive system, and includes a vehicle body 21, left and right wheels 22, 23, two fluid pressure motors that drive these, and two variable fluid pressure pumps that supply pressurized fluid to each motor. , one engine that drives both pumps, and two left and right steering levers that control each variable fluid pressure pump.
4, 25, accelerator lever 2 that controls the engine
6. Approximately L-shaped boom 27, bucket 28, boom cylinder 29, bucket cylinder 30, boom control valve 31 for the boom cylinder, bucket control valve 32 for the bucket cylinder, boom pedal 33 for the boom control valve, bucket A bucket pedal 34 for the control valve, a brake pedal 35, a seat 36, a head guard 37 with a protective wire mesh attached to the parts except the front, a control box 38, and a seat bar 3.
By tilting the left and right steering levers 22 and 23, it is possible to move forward, reverse, change directions, and even turn on the spot.

The control box 38 is connected to the seat 36.
Switches 40 (starter switch, horn button, light switch, glow plug, etc.) and meters 41 (hour meter, engine water temperature, oil pressure warning light, HST filter, oil temperature warning light, etc.) ) are provided.

In the case of the skid steer loader 20, since the operator boards the skid steer loader from the front, the control box 38 is placed closer to the front right side.

The seat bar 39 is provided in place of a seat belt to protect the operator from impact in the event of a collision, etc. The seat bar 39 is approximately U-shaped in plan, and its base end is part of the vehicle body 21. It is pivotally attached to a head guard 37, which is a section, so as to be able to move up and down, and a rubber 42 is attached to the bending section so as to make flexible contact with the abdomen of the operator.

The seat bar 39 can be placed in the mounting position shown by the solid line in FIG. 4 and in the storage position shown by the chain line.
It has the advantage that it is extremely easy to put on compared to a seat belt.

However, when the operator operates the switches 40 of the control box 38 or checks the meters 41 with the seat bar 39 in the installed position, the operator's movements are restricted by the seat bar 39. This poses a problem in that this operation and confirmation cannot be performed easily.

(Problems that the invention attempts to solve) This invention was created in view of the problems mentioned above and to solve them, and its purpose is to:
To provide a vehicle equipped with a seat bar in which it is extremely easy to operate switches in a control box and check meters when the seat bar is installed.

(Means for Solving the Problems) A vehicle equipped with a seat bar of the present invention has a substantially U-shape in plan view, and its base end is pivoted to a part of the vehicle body, and its bent part is mounted close to the operator's abdomen. A vehicle equipped with a seat bar having a seat bar that can be raised and raised freely from one position to a storage position that is far away is characterized in that a control box having switches and meters is attached to a bent part of the seat bar.

In other words, the location of the control box has been changed.

(Function) When the operator sits on the seat and moves the seat bar from the storage position to the installed position, the operator can be protected from impact in the event of a collision, etc.

When the seat bar is in the installed position, the control box is located at the bend of the seat bar, making it easy to operate the switches and check the meters provided here.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a partially cutaway side view of a vehicle equipped with a seat bar according to an embodiment of the present invention. Figure 2 shows
FIG. 3 is an enlarged perspective view showing the seat bar and the control box.

The main parts of a seat bar equipped vehicle 1 include a seat bar 2 and a control box 3.

The seat bar 2 has a substantially U-shape in plan view, and its base end is pivoted to a part of the vehicle body 4 so that it can be raised and lowered from a mounting position to a storage position.

In this example, the steel pipe is U-shaped in plan, and the side surface is approximately L.
The proximal end of the head guard 5 is bent into a shape and is pivoted to the rear post of the head guard 5 attached to the upper part of the vehicle body 4 by pins 6 in the left and right directions so as to be able to move up and down freely. Rubber 7 is attached.

Mounting brackets 8 are protruded near both sides of the rubber 7, and through holes 9 and 10 are bored in this vicinity and midway through one arm.

The control box 3 has switches 11 and meters 12 and is attached to a bent portion of the seat bar 2.

In this example, it has a box shape and is attached to the mounting bracket 8 by bolts (not shown) so as to be located in front of the rubber 7, and switches such as a starter switch, horn button, light switch, glow plug, etc. are mounted on the top surface of the mounting bracket 8. 11, meters 12 such as an hour meter, engine water temperature, oil pressure warning light, HST filter, oil temperature warning light, etc. are arranged, and these wiring 13 is provided with connectors 14 and 15 in a part, By inserting it into one arm of the seat bar 2 through the through holes 9 and 10, it does not get in the way.

Next, the operation will be explained based on such a configuration.

After the operator sits on the seat, the seat bar 2, which is in the stowed position shown by the chain line in FIG. 1, is moved down to the mounting position shown by the solid line in FIG.

In this way, the rubber 7 of the seat bar 2 comes into contact with the operator's abdomen, so that the operator can be protected from the impact in the event of a collision or the like.

When the operator operates the switches 11 or checks the meters 12 with the seat bar 2 in the installed position, the control box 3 containing these is installed at the bend of the seat bar 2, so the operator does not have to stretch his/her body. These operations and checks can be performed without bending.

Although the seat bar equipped vehicle 1 is a skid steer loader in the previous embodiment, it is not limited to this, and may be, for example, another type of cargo handling vehicle or a general automobile.

In the previous embodiment, the seat bar 2 has a shape that is approximately U-shaped in plan and approximately L-shaped in side, but the shape is not limited to this, and the design can be changed as appropriate.

In the previous embodiment, the control box 3 is
Although it is arranged to be located in front of the rubber 7, it is not limited to this, and may be arranged separately, for example, on one side or both sides of the rubber 7.

The specific items of the switches 11 and meters 12 are not limited to those in the previous embodiments, and any necessary items may be provided as appropriate.

(Effects of the invention) As described above, according to the present invention, the following excellent effects can be achieved.

(1) Since the control box is provided on the seat bar, it is extremely easy to operate the switches in the control box and check the meters when the seat bar is installed.

(2) Since the control box is provided on the seat bar and not on the front of the vehicle body, the space in this area becomes wider, making it easier for the operator to operate the vehicle and get on and off the vehicle.

(3) Since the switches in the control box, such as the starter switch, cannot be operated unless the seat bar is in the installed position, the seat bar must be installed, which prevents the seat bar from becoming attached, and improves safety. Excellent.

(4) Since it is only necessary to change the mounting position of the control box, it is easy to implement and does not require much cost.
