[0001]

[Industrial applications]

 The present invention relates to an accelerator pedal device mounted on an industrial vehicle such as a forklift truck.

[0002]

[Prior Art]

 Conventionally, an accelerator pedal device mounted on an industrial vehicle such as a battery-powered forklift truck detects the amount of depression of the accelerator pedal 2 on the lower surface of an accelerator pedal 2 pivotally mounted on a floor plate 1, as shown in FIG. For this reason, the accelerator 3 is fixed to a part of the floor plate 1, and the tip of the movable rod 7 of the accelerator 3 is in contact with the lower surface of the accelerator pedal 2 via the roller 8. 7 is biased upward by a spring in the accelerator 3.

[0003]

[Problems to be solved by the device]

 In such a conventional accelerator pedal device, the force of depressing the accelerator pedal (hereinafter referred to as accelerator pedal depressing force) is a force that opposes the spring force in the accelerator, but the strength of this spring has been adjusted to a constant value. However, since the physical strength and the feeling of stepping on the worker differ depending on the worker, some workers may feel a sense of discomfort with the strength of the spring. The present invention aims to solve this problem.

[0004]

[Means for Solving the Problems]

 According to the present invention, in the accelerator pedal device, by providing a means for changing the contact angle between the accelerator pedal side and the accelerator rod side, it is possible to change the accelerator pedal depressing force and prevent the operator from feeling uncomfortable. ..

【Example】

 A first embodiment of an accelerator pedal device for an industrial vehicle according to the present invention will be described with reference to FIGS. 1 (a) and 1 (b). An accelerator pedal device configured by an accelerator pedal 2 pivotally attached to a floor plate 1 below a driving section of an industrial vehicle, and an accelerator 3 arranged on a lower surface of the accelerator pedal 2 for detecting a depression amount of the accelerator pedal 2. In the above, a plate member 5 is rotatably fixed to the lower surface of the accelerator pedal 2 via a hinge member 4, and a bolt 6 screwed to the lower surface of the accelerator pedal 2 is brought into contact with the tip end side of the plate member 5. .. Then, the tip of the rod 7 of the accelerator 3 is brought into contact with the lower surface of the plate member 5 via the roller 8.

In such a configuration, the bolt 6 is tightened or loosened to change the distance between the accelerator pedal 2 and the tip of the rod 7 of the accelerator 3 so that the accelerator pedal 2 side and the rod 7 side of the accelerator 3 are connected. By changing the contact angle of, you can change the accelerator pedal effort. As shown in FIG. 2, assuming that the contact angle between the accelerator pedal 2 side and the rod 7 side of the accelerator 3 is θ, the accelerator pedal depression force F becomes a component force Fb of the accelerator pedal depression force F 2. And acts against the spring force in the accelerator 3, the component force Fb increases as θ approaches 90 °, so that the accelerator pedal depression force F can be reduced. Further, as θ approaches 0 °, the component force Fb decreases, so the accelerator pedal depression force F can be increased.

Next, a second embodiment will be described with reference to FIG. In an accelerator pedal device composed of an accelerator pedal 2 and an accelerator 3, two bolts 9 are fixed to the lower surface of the accelerator pedal 2 downward, a shim 10 is attached to each of the bolts 9, and a plate member is further provided. Attach each bolt 9 with a nut 11 so that 5 is suspended. Then, the tip of the rod 7 of the accelerator 3 is brought into contact with the lower surface of the plate member 5 via the roller 8. With such a configuration, by changing the number of the shims 10 attached and changing the distance between the accelerator pedal 2 and the tip of the rod 7 of the accelerator 3, the accelerator pedal 2 side and the accelerator 3 side can be changed as in the first embodiment. Change the contact angle with the rod 7 side and change the accelerator pedal depression force.

Further, a third embodiment will be described with reference to FIG. In an accelerator pedal device including an accelerator pedal 2 and an accelerator 3, an upper end of a mounting plate 12 to which the accelerator 3 is fixed is rotatably fixed to a floor plate 1 and a lower end of the mounting plate 12 is fixed to the lower plate 1. A hole is provided and a bolt 13 fixed to a part of the floor plate 1 projecting downward is passed through the hole. Then, the nut 14 is attached to the bolt 13 to fix the accelerator 3. With such a configuration, the fixing position of the accelerator 3 is changed by the rotation of the nut 14, the contact angle between the accelerator pedal 2 side and the rod 7 side of the accelerator 3 is changed, and the accelerator pedal depression force is changed.

[0009]

[Effect of the device]

 The present invention, in the accelerator pedal device, by providing the means for changing the contact angle between the accelerator pedal side and the rod side of the accelerator, it is possible to change the accelerator pedal pedal force suitable for each worker, Work efficiency can be improved by preventing the operator from feeling uncomfortable.
