A motorized wheelbarrow assembly for includes a wheelbarrow that has a pair of handles and a wheel rotatably coupled between the pair of handles. The wheel may roll along a support surface. A drive unit is coupled to the wheelbarrow. The drive unit is in mechanical communication with the wheel. The drive unit selectively rotates the wheel to urge the wheelbarrow along the support surface.

The disclosure provides a vehicle drive system that includes a drive pedestal, a drive motor mounting plate connected to the drive pedestal, an electric drive motor assembly having an output shaft and being connected to the drive motor mounting plate, at least two bearings connected to the drive pedestal, an axle shaft rotatably connected to the at least two bearings, a drive wheel connected to the axle shaft, a chain drive assembly, and a controller that provides control signals to the electric drive motor assembly and is connected to the drive pedestal. The electric drive motor assembly also includes a first gear speed reduction, while the chain drive assembly includes a second gear speed reduction.

In the specification and drawings an accessory cart is described and shown with a base, a housing element that is connected to the base and extends upward from the base, and a platform, which is connected to the housing element with the height of the platform being automatically adjustable.

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.

A walking assist device has a frame, a plurality of wheels, drive units, a battery, and a drive control unit that controls the drive units. The walking assist device also has: a pair of right and left movable handles that are grasped by a user and movable back and forth with respect to the frame in accordance with arm swing performed during walk of the user; handle guide units provided on the frame to guide the movable handles in a movable range that matches the arm swing performed during walk of the user; and a grasp portion state detection unit that detects the state of the movable handles. The drive control unit controls the travel speed of the walking assist device by controlling the drive units on the basis of the state of the movable handles which is detected using the grasp portion state detection unit.

The invention relates to an electric motor (24) designed for driving a vehicle (10) which can be moved by a person, particularly a pram (11), walker or the like, having a rotor (52), which comprises at least one holder (80) for a wheel (14, 16), and a stator (54) which can be connected through a housing (38) to a load-bearing structure (12) of the vehicle (10). According to the invention, the housing (38) has a status display (84) on which parameters, particularly power parameters, of the electric motor (24) can be displayed so as to be visible from the outside.

A container moving assembly includes a frame with a drive wheel pivotably attached to the frame about a steering axis. A pair of guide wheels are rotatably attached relative to the frame opposite the drive wheel. A platform lifting assembly is pivotable relative to the frame and includes an engagement platform for supporting a container.

The present invention relates to an electric propulsion system (1) for a rolling object, comprising a chassis (2) with at least one motorized wheel (3) and at least one non-motorized wheel (4), a handlebar (6), coupling means (5) and drive assist means. The coupling means are intended for gripping, orienting, immobilizing and lifting of at least one wheel (14) of rolling object 13). The drive assist means comprise at least one arm (36) of variable length for varying the distance between the at least one driven wheel (3) and the at least one non-driven wheel (4). The present application also concerns a coupled assembly comprising the electric propulsion system and a method of using the electric propulsion system.

Stroller frame comprising at least one electric motor, for assistively driving the stroller frame, at least one wheel connecting device, in particular wheel axle, and at least one battery module connected or connectable to the wheel connecting device, which in the assembled state is arranged at least partly outside the wheel connecting device and is arranged at least predominantly below a level of an upper end of the wheel connecting device or is arranged at least partly below the wheel connecting device.

A galley cart assembly that includes a cart and a wheel assembly attached to the cart. The wheel assembly includes a plurality of wheels and a drive assembly configured to drive one or more of the plurality of wheels to propel the cart. The wheel assembly also includes a primary brake assembly to lock one or more of the plurality of wheels to prevent movement of the cart. Furthermore, the galley cart assembly includes a controller coupled to the cart and including a processor and a memory. The controller includes a turbulence monitoring system configured to detect a turbulence event. The controller is in communication with the wheel assembly, and is configured to automatically operate the primary brake assembly to lock the cart in position when the turbulence monitoring system detects the turbulence event. In certain configurations, an aircraft includes the galley cart assembly.
