  • Publication number: 20040129486
    Abstract: A driver control input device includes left and right control posts each having a hand grip. The control posts are movable forwardly and rearwardly and are sufficiently linked together such that forward movement of one control post will result in an equal and opposite rearward movement of the other control post to facilitate sending non-mechanical steering signals to a steer-by-wire system to which the control input device is attached. Accelerator demand input mechanisms and braking demand input mechanisms may also be positioned on the hand grips for generating non-mechanical acceleration and braking signals.

The reminder device is designed with safety in mind and give a vehicle operator a visual and/or audio signal, after a predetermined time, that a left turn signal or right turn signal on the vehicle needs to be turned “off”. The reminder device includes an electrical circuit housing with housing carrier and straps for securing the housing on the instrument panel of the motorcycle. The electrical circuit housing includes electrical leads for connecting the housing to the vehicle's left and right turn signals, a lead for connecting to the vehicle's battery for providing a power source to the housing, leads connected to an audio/visual unit mounted on the instrument panel and a lead connected to the motorcycle's brake signal light. Also, the circuit housing includes an audio/visual control knob and a time delay control knob.

  • Publication number: 20020092694
    Abstract: A skid-steer mini-loader (10) has a compact chassis formed by two side walls (11,12) fixed to either side of a tank (13) which forms an oil reservoir for a hydraulic drive system for the mini-loader. A hydraulic pump (30) is located within the tank (13), and is driven by an engine (31) mounted directly on top of the tank. A console panel (19) having controls (20) thereon forms the rear wall and top of a cover for the power plant. The console panel is pivotally mounted at its lower end to the chassis, enabling the panel (19) to be opened out and thereby facilitate access to the power plant.

  • Publication number: 20020084135
    Abstract: A method of automatically setting an auxiliary hydraulic valve's flow rate and returning to that flow rate automatically is disclosed. The work vehicle such as a backhoe has two hand controls, one of which has a button, and the other has a thumb wheel. To set the hydraulic flow rate, one both presses the button one hand control and moves the thumb wheel on the other hand control until the proper flow rate is reached. At this point, both button and thumb wheel are released. This causes the flow rate to be saved in RAM or ROM memory. The flow rate can be varied at any time by rolling the thumb wheel up or down. One can return to the previously save flow rate by pressing the button. Both controls are preferably spring loaded.

  • Patent number: 6390225
    Abstract: A zero-turning radius self-propelled power lawn mower includes a standing platform structure for supporting a standing operator during mower operation. The mower has a combination parking brake and pump lockout structure which, when actuated, simultaneously applies a braking force to rear drive wheels and prevents hydro pumps from being moved from their neutral positions. The mower also includes a biasing system for automatically returning hand control levers to their neutral positions when they are not being manipulated by an operator. Unique cutter deck structure, caster structure, grass catcher structure, and steering control levers are also provided.

  • Publication number: 20020053479
    Abstract: A motorized vehicle includes left and right electric motors mounted on a vehicle body for independently rotating left and right driving wheels, respectively, at variable speeds, and an actuator for causing the left and right electric motors to rotate simultaneously in opposite directions, thereby ensuring that the vehicle making a turn through a desired angle while staying at the same position. The actuator includes left and right turn control levers respectively mounted to left and right handlebars so as to extend along left and right handgrips. The turn control levers are operationally connected to left and right brakes and the left and right electric motors for causing the simultaneous rotation of the motors in opposite direction based on the position of the turn control levers.

  • Publication number: 20020014357
    Abstract: An omni direction vehicle with a frame having a round surface about its perimeter with no apparatus mounted on the frame extending beyond the perimeter. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently of the other and can rotate at variable speeds in either direction. The vehicle is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The vehicle can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground. Thus, the vehicle requires a zero turning radius and requires only the space it occupies to change its forward orientation.

  • Patent number: 6343668
    Abstract: A foldable control lever for use with a riding mower comprising a main lever tube having a lower end, an upright section and a grip portion. An upper weldment is affixed to the lower end of the main lever tube. The upper weldment comprises a support flange and a plurality of outwardly projecting ears. A lower weldment connected to the mower drive unit is adapted to receive the lower end of the main lever tube. The lower weldment comprises a receiver flange having a plurality of notches spaced about the circumference of the flange. The notches are configured so as to engage the outwardly projecting ears of the upper weldment. When the outwardly projecting ears are engaged with the notches, the main lever tube is prevented from rotating relative to the lower weldment. When the outwardly projecting ears are not engaged with the notches, the main lever tube can be rotated downward and on to the top of the mower.

    Abstract: To provide a small-sized vehicle in which a convenient pocket is provided in a single driver's seat portion. Furthermore, a brake master cylinder is disposed by making effective use of space without reduction of the capacity of the pocket, and the maintenance of a reservoir tank of the brake master cylinder thus disposed is ensured. A meter cover portion is disposed in a pocket of an inner panel at a position offset rightwardly from the center in the width direction of the vehicular body to form small and large capacity pocket parts on the right and left sides of the vehicle. A brake pedal is disposed on the right side of a steering column extending in an approximate center line in the width direction of the vehicular body, and a brake master cylinder connected to the brake pedal is disposed behind the meter cover portion. Such a layout is advantageous since it allows a driver to easily operate the pedals while ensuring the pocket capacity.
