A motorized scooter cart system is a system that enables a user to comfortably move around while transporting objects or people. The system may include a scooter deck, at least one scooter wheel, a linkage arm, at least one seat assembly, a handlebar assembly, and a pushcart. The scooter deck is designed to support the weight of the user so that the user can freely maneuver the pushcart. The at least one scooter wheel provides the translational force necessary to move the present invention. The linkage arm enables the coupling of the scooter deck to the pushcart. The linkage arm also facilitates the maneuvering of the pushcart. The at least one seat assembly enables the user to comfortably seat while maneuvering the pushcart. The pushcart enables the transportation of objects or people mounted onto the pushcart. Finally, the handlebar assembly enables the control of the pushcart by the user.

A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

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.

According to an example of the present disclosure, there is provided an electric board that can switch between automatic and manual operation including a frame configured to accommodate an occupant; a plurality of wheels moving the electric board; a plurality of motors respectively installed on the wheels; and a lever coupled directly to the motor and configured to manually cut off electric power applied to the motor through an operation of a user. When the electric power applied to an electronic brake provided in the motor is cut off by the lever, an operation of the electronic brake which controls a gearwheel of the motor by the electric power is stopped, and the electric board is configured to be converted into a state of being controlled by manual power of the user.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

A riding vehicle includes: a main body portion supporting a wheel; a seat stay erected on the main body portion and configured to be switched between a riding state in which a person rides and a cart state in which a person does not ride; a seat fixed to an upper side of the seat stay; a frame provided on the seat stay and configured to hold luggage in the riding state and the cart state; a steering stay erected on the main body portion at an interval with respect to the seat stay in a traveling direction; and a handle provided on the steering stay, in which the frame, in the cart state, exists in a region closer to the handle as compared with that in the riding state.

Embodiments of an electric power-assisted wheeled child carrier are provided herein. The electric power-assisted wheeled child carrier, such as a stroller for example, includes an electric drive mechanism for electrically powering rotation of at least one wheel of the child carrier. The electric power mechanism includes a motor, an output shaft coupled to the motor that is configured to rotate the output shaft, a wheel shaft coupled to the wheel being powered; and a clutch positioned between the output shaft and the wheel shaft. The clutch is configured to move axially between an engaged state and a disengaged state. In the engaged state, the output shaft powered by the motor drives rotation of the wheel, and in the disengaged state, the wheel is configured to rotate without power from the motor.

A drive wheel in which the rotational axial center of a wheel along the vertical direction intersecting the axial center of the axle is arranged shifted in the horizontal direction orthogonal to the axial center of the axle with respect to the axial center of the pivot shaft. When a radius R1 of the wheel, center distance R2 between the rotational axial center and the axial center of the pivot shaft, rotational frequency n1 of the wheel, rotational frequency n2 of the pivot shaft, rotational speed V1 of the wheel, and steering rotational speed V2 of the wheel rolling on a floor surface while turning the pivot shaft satisfy V1=V2, relations of V1=2R1n1, V2=2R2n2, and n1=n2 (R2/R1) are satisfied.

A stroller frame, comprising at least one motor, particularly an electric motor, for assisted driving of the stroller frame, a pusher bar for pushing the stroller frame and at least one force sensor device for detecting a direction and/or an amount of force and/or a force component acting on the pusher bar, and/or for detecting a value derived from said force or force component, particularly a temporal change of the force or force component.

A cart includes a hub, a frame, and at least one handlebar. The frame includes a first segment and a second segment, and the first segment, the second segment, and the handlebar are each supported by the hub. The hub defines a rotational axis and at least two of the first segment, the second segment, and the handlebar are rotatable about the rotational axis relative to each other and the hub. At least one wheel is on the first segment and at least one wheel is on the second segment.
