A wagon with a height reduced after being folded includes four telescopic standing posts arranged in a rectangle pattern and at intervals, and at least two side folding mechanisms arranged opposite to each other. Two ends of the side folding mechanism are respectively hinged to two adjacent telescopic standing posts. When the wagon is folded, the side folding mechanisms drive the telescopic standing posts connected thereto to retract and shorten. When the wagon is unfolded, the side folding mechanisms drive the telescopic standing posts connected thereto to extend. The wagon has a height in a folded state smaller than a height thereof in an unfolded state. When the wagon is folded or unfolded, the folding mechanisms drive the telescopic standing posts to retract or extend. Therefore, after the wagon is unfolded, the space for a fabric bed provided on tops of the telescopic standing posts is increased.

The purpose of this invention is to combine a four-legged type of stool with a hand cart. This is useful for, but not limited to, performers, for example, who have to haul in amplifiers and road cases etc. to a venue, then perform sitting down. With this invention the integral combination of hand cart and stool allows the user to load in equipment, then convert the hand cart to a stool on which to sit. Then convert it back to a hand cart to load equipment back out. This is accomplished by the new integration of additional vertical structures and connectors to the hand cart design, which upon expansion and inversion, become the front legs for the stool. When inverted, the bottom plate structure of the hand cart becomes the seat.

The wagon with the height reduced after being folded includes four telescopic standing posts arranged in a rectangle pattern and at intervals, and at least two side folding mechanisms arranged opposite to each other. Two ends of the side folding mechanism are respectively hinged to two adjacent telescopic standing posts. When the wagon is folded, the side folding mechanisms drive the telescopic standing posts connected thereto to retract and shorten. When the wagon is unfolded, the side folding mechanisms drive the telescopic standing posts connected thereto to extend. The wagon has a height in a folded state smaller than a height thereof in an unfolded state. When the wagon is folded or unfolded, the folding mechanisms drive the telescopic standing posts to retract or extend. Therefore, after the wagon is unfolded, the space for a fabric bed provided on tops of the telescopic standing posts is increased. In addition, after the wagon is folded, the telescopic standing posts shorten, reducing the space occupied by the wagon, making it easy to carry and transport.

The sliding accessory (200, 300) of the invention comprises a base plate (210) for sliding on snow, elongated along a first axis (XX) and presenting faces facing along a second axis (ZZ) perpendicular to the first axis, as well as a wheel chock (220) removably attached to the wheel (130) of the stroller. The wheel chock defines a housing for receiving the lower part of the wheel, which opens towards the top along the second axis and is bounded by a bottom wall arranged transversely to the second axis and by two side walls arranged parallel to the first and second axes and facing each other along a third axis (YY) perpendicular to the first and second axes. Each side wall is provided with a relief protruding towards the other side wall along the third axis. The relief is arranged to cooperate in contact with the tire (131) of the wheel such that relative movement between the attachment and the wheel along the second axis reversibly transitions the attachment between an in-use configuration in which the relief presses the tire along the second axis against the bottom wall and forces a lower portion of the tire into a lower portion of the housing to secure the sliding attachment to the wheel, and an out-of-use configuration in which the attachment is removed from the wheel and the tire is resiliently pressed against the relief along a third axis as the attachment transitions between the two configurations.
