Abstract
A vehicle system includes a chassis, a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface, and a riding platform coupled to the chassis. The riding platform is for supporting a user behind the chassis when the riding platform is in a downward pivoted state. A linkage connects the riding platform to the chassis for selective pivotal motion relative to the chassis between an upward pivoted state in which the riding platform is pivoted into a position to allow a user to walk behind the chassis and a downward pivoted state in which the user may ride or step on the platform.
Claims21
A vehicle system comprising:
- a chassis;
- a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface;
- a riding platform coupled to the chassis, the riding platform for supporting a user behind the chassis when the riding platform is in a downward pivoted state;
- a linkage connecting the riding platform to the chassis, for selective pivotal motion relative to the chassis between an upward pivoted state in which the riding platform is pivoted into a position to allow a user to walk behind the chassis;
- and
- a container supported on the chassis, the container having two side walls, an opening between the two side walls, and a sliding door that selectively slides between a closed position to at least partially cover the opening and an open position to uncover the opening, wherein each of the side walls is collapsible or foldable from an expanded state to a collapsed or folded state while the container is supported on the chassis and when the sliding door is in the open position.
A vehicle system comprising:
- a chassis;
- a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface;
- a riding platform coupled to the chassis, the riding platform for supporting a user behind the chassis when the riding platform is in a downward pivoted state;
- a trailer having a frame or platform and a plurality of wheels connected to the frame or platform for supporting the frame or platform for rolling on the surface;
- a linkage structure for selectively coupling the trailer to the riding platform;
- at least one container supported on the frame or platform of the trailer, the at least one container having an interior volume for containing one or more objects;
- and
- at least one container lifting system supported on the frame or platform of the trailer, for selectively lifting the container off of the frame or platform of the trailer;
- wherein the lifting system comprises:
- a second frame or platform for holding the at least one container;
- and
- a plurality of legs pivotally connected to the second frame or platform, for pivoting between a retracted state and an extended state;
- wherein, upon pivoting to the extended state, the plurality of legs extend downward below the second frame or platform to engage a ground surface and to raise the second frame or platform above the frame or platform of the trailer.
