The electric stroller comprises a frame, a child seat, an operator seat, a plurality of wheels, a port motor, a starboard motor, a control circuit, and a battery. The electric stroller may be a self-propelled conveyance. The child seat may be supported by the frame and may be adapted to transport a child. The operator seat may be coupled to the frame behind the child seat and may be adapted to transport an operator. A port driven wheel may be propelled by the port motor and a starboard driven wheel may be propelled by the starboard motor with the speed and direction of the port motor and the starboard motor controlled independently.

A motorized stroller assembly includes a carriage frame. A plurality of wheels is rotatably attached to the carriage and a child seat is positioned in the carriage frame. An electric motor is mechanically coupled to at least a first wheel of the plurality of wheels. The motor selectively rotates the first wheel to drive the carriage frame forward. A battery is mounted on the carriage frame and is electrically coupled to the motor. A control is mounted on the carriage frame and is electrically coupled to the motor and is actuated to drive the first wheel in the first direction. A platform is attached to a rear side of the carriage and extends rearwardly therefrom. The platform is positioned near a bottom of the carriage. The platform supports a person standing on the platform. A canopy is pivotally coupled to the carriage frame and is extendable over the child seat.

Embodiments of the present disclosure are directed to a cart frame and modular, motorized cart. In some examples, the cart frame may comprise a wheel assembly, handles, and a kickstand. A modular article (e.g., litter, stretcher, game basket, etc.) may be attached to the top portion of the cart frame via at least one fastener (e.g., buttons, snaps, hooks, buckles, quick-detach mounts, etc.). The handles may be foldable and extendable. The kickstands may also be foldable and extendable. The handles, in some embodiments, may serve a dual purpose by folding to a certain length to function as a kickstand. In other examples, the cart may comprise an engine that may be gas-powered or electric. A battery may be affixed to the cart frame that powers the electric engine. Other objects may also be attached to the cart frame and/or modular article, such as a winch, tow bar, light, bumper, etc.

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.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

Disclosed is a wagon having improved convenience of use, wherein the wagon includes a main frame, a seat frame, a canopy frame, and a wheel assembly, wherein a foldable structure of each frame is conveniently manufactured such that the wagon can be unfolded and folded within a short time when the wagon in a stored state is installed, whereby portability and mobility of the wagon are improved, wherein the overall frame is easily folded and unfolded, whereby it is possible to conveniently use the wagon, wherein attachment and detachment of the canopy and the driving wheels are easy, whereby carrying and storage of the wagon are easy, and wherein the wagon is easily folded and unfolded without separation of the seat frame and the canopy, whereby it is possible for everyone to easily install and store the wagon.
