A stroller includes a frame, a handle, a plurality of support legs, a wheel attached to a lower end of each support leg, and a seat attached to the frame. The seat includes an internal Peltier device for selectively heating or cooling the seat. The Peltier device is powered via an onboard battery installed in an electronics housing that includes multiple USB ports. A blanket is removably secured to the seat via one or more fasteners. A processor in the electronics housing performs a method that includes activating the Peltier device to bring the seat to a preset temperature, receiving a temperature setting for the Peltier device from a temperature control button disposed on the handle, detecting a current temperature of an area within the seat, and if the current temperature of the area within the seat is greater than a threshold safe upper temperature, then deactivating the Peltier device.

A system including an adapter configured to releasably couple a rider board to stroller that has at least one support bar. The adapter is configured to be coupled to a frame of the stroller, where the adapter includes an engagement bar configured to be positioned rearwardly of a portion of the frame to which the adapter is coupled. The adapter includes a body having a recess configured to closely receive the at least one support bar of the stroller therein.

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.

A motorized stroller for a theme park including a platform and an ergonomic configuration. The platform enables an operator to stand thereon in order to use it for automated travel. A touch screen display is accessed from the platform to illustrate attraction location, wait times, time, date, local dining, and online ordering options. Additionally, a user may also operate steering of the stroller when standing on the platform. The steering mechanism of the stroller includes a right handle which is manually rotated in a backwards motion to accelerate the stroller in a forward direction. A left handle may be rotated backwards for a reverse motion. Furthermore, the steering wheel includes brake handles to bring the stroller to a stop. In the present embodiment the steering handle also comprises of a key entry to turn the stroller on and off as well as a horn.

The disclosure provides a noise reduction structure comprising a stroller frame, a supporting frame connected to the stroller frame, and a wheel mounted on the supporting frame, the supporting frame receive a force so that the wheel contacts a supporting surface to slide; and an elastic resetting member is arranged between the supporting frame and the stroller frame, the resetting member always has a tendency to bring the supporting frame to reset. The noise reduction structure of the disclosure has a simple structure and is suitable for baby strollers or hand carts. By additionally arranging a resetting member between the supporting frame and the stroller frame, the supporting frame always has a resetting tendency, that is, when the supporting frame is unloaded, the resetting member may suspend the wheel, so as to avoid noise caused by friction between the wheel and the supporting surface.

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.

An adjustable height cart height adjustable cart includes a frame extending in a longitudinal direction from a front end of the cart to a rear end of the cart. The frame includes a base provided with casters and a height adjustable frame connected to the base. The height adjustable frame is configured to be raised or lowered relative to the base. The height adjustable frame includes a lower shelf and an upper shelf. The upper shelf has an opening for loading and unloading items onto the cart. A handle is connected to the base at the rear end. A lower tote is slidably mounted on the lower shelf so as to move in a lateral direction. A top tote is slidably mounted on the upper shelf so as to move in the longitudinal direction forward and backward to enable loading of the lower tote through the opening.

A moving device adapted to be actuated by a prime mover is disclosed. The moving device allows a caregiver to ride thereon. The moving device comprises a vehicle body and a plurality of rotors. The vehicle body includes a first frame portion and a second frame portion. The first frame portion allows the caregiver to ride thereon and the second frame portion allows a care receiver to ride thereon. The plurality of rotors are provided on the first frame portion and are rotatable in accordance with movement of the vehicle body. A wheel base defined by the plurality of rotors is constant. The second frame portion is provided on the first frame portion so as to be movable in accordance with a motion of the caregiver riding on and getting off the first frame portion.
