  • Patent number: 10384704
    Abstract: A steerable, self-propelled cart for safely delivering heavy loads, such as concrete, within job sites with unlevel, irregular, or sloped terrain. A cargo bucket is tiltable over front drive wheels for transporting and dumping cargo. Hydraulic drive motors driven by a hydraulic pump propel rear wheels at a selectable speed. Steering handlebars rotate a steering column that turns the rear wheels. A throttle cable extending from the handlebars controls the throttle setting by pivoting a throttle lever mounted on the hydraulic pump. Limiting linkages extend from flanges on an anchor bracket secured to the steering column to a bridge on the throttle lever. As the steering column rotates, the limit linkages are wound partially about it, pivoting the throttle lever by pulling on the bridge, reducing pump speed. Heavy steering displacements will retract the throttle lever to reduce cart speed notwithstanding the previous speed setting chosen by the operator via the cable.

  • Patent number: 10093337
    Abstract: A gyroscopically-responsive power assisted moment arm is disclosed for use in connection with vehicles such as load carrying devices. A moment arm extends to a pivot point such that when a longitudinal force is applied at the moment arm, a sensor senses such force and outputs an energizing signal to a motor to drive a wheel. If a rotational or vertical force is applied to the moment arm, the motor need not be driven. According to the invention, therefore, a power assist can be provided to a user to drive a wheel in a desired direction of transport while not causing drive during tipping or unloading of the load carrying portion of the vehicle. Such an apparatus can be advantageously applied to a power assisted wheelbarrow, as one exemplary application.

  • Patent number: 9682723
    Abstract: Foot operated control linkages overlie the conventional control lever operating system on a spin turn mower to operate the mower in either forward or reverse directions. Each control linkage uses a foot pedal to control the speed of the mower while the control levers remain operable, even while the mower is moving, to change the forward or reverse direction of travel of the mower. The forward control linkage includes a first set of springs that pull the control levers against a stop while a second control spring prevents the first springs from moving the mower until the foot pedal is depressed. Thus, when the foot pedal is allowed to return to a non-depressed position, the mower will revert to a neutral detent position in which the mower is not powered in any direction.

  • Patent number: 8490373
    Abstract: A push mower comprises a mower main body, at least one arm extending upward toward a rear side from the mower main body, and a grip located at a tip end of the at least one arm. Each end of the grip is located on one plane side of an arm plane, a center of the grip is located on an opposite plane side of the arm plane, and therefore the grip extends so as to intersect with the arm plane. Here, the arm plane means a virtual plane on which the at least one arm is located and that is parallel to a left-to-right direction of the mower main body.

  • Patent number: 8467937
    Abstract: A power steering assist system for a hand-steered pallet truck includes a joint assembly having a pivot joint, handle biasing mechanism, and a torque sensing arrangement. The pivot joint includes a pair of needle bearings and pivot pin disposed within a pivot block that provides a flexible connection between a handle and a tiller arm. The handle biasing mechanism includes a cantilevered beam spring and two cam rollers that resists an operator steering force applied to the handle and further, centers the handle with respect to the tiller arm after the force is released. The torque sensing arrangement includes a magnet and a non-contact magnetoresistive (MR) sensor that measures movement of the handle relative to the tiller arm which is used to determine operator steering intent, i.e., the amount of steering force applied to the handle. The MR sensor provides accurate torque measurements regardless of the angle of the tiller arm.

  • Patent number: 8327961
    Abstract: Walk-with apparatus (101), e.g. a powered golf-caddy (101), has a reference member (18), a handle (1) adapted to be used to hold and guide the apparatus, and rotary mechanical damping means (13, 14), the handle 1 being movable in a forwards and backwards direction (103) relative to the reference member (18) to produce electric signals (104) to vary the speed of the (apparatus 101), under the effect of the damping means (13, 14) thereby to inhibit hunting. In addition to spring means (6, 8) and a DC motor controller (110) with an acceleration ramp, the damping means (13, 14) is needed to give smooth motion. The handle (1) has rotary cam means (80, 81, 90) to lock it in any position along direction (103), with a 45° rotation either way at any angle.

  • Patent number: 8312946
    Abstract: A trigger 52a control apparatus is provided for operating a transmission 44 of a self-propelled mowing machine 20 via a cable 42 between a halt condition and an advancement condition. The trigger 52a control apparatus includes a housing 100, and a plurality of independently operable triggers 52a rotatably coupled to the housing 100 for movement between an engaged and a disengaged position 104. Each trigger 52a includes an operation member 108a. A cam 114 is rotatably coupled to the housing 100 about a cam rotation axis 116 and operatively coupled to the cable 42, wherein rotation of the cam 114 in a first direction relatively increases tension in the cable 42. An actuation member 138 is coupled to the cam 114 a distance from the cam rotation axis 116.
