The invention provides a trailer with no extra height when folding, comprising fixed standpipes arranged at a front and rear end of the trailer, and front and rear folding components, side folding components, bottom folding components and handle components connected to the fixed standpipes. The height of the trailer in the invention does not change after folding to ensure that the height after folding and the height in use are the same, thereby the object that the volume after folding is smaller than that of the prior trailer. By proving telescopic components on the handle components, the trailer can be telescopically folded by handle components when not in use, which reduces space occupation and is practical and convenient; simultaneously, by providing reset torsion spring on the handle components, the object of automatically resetting of the handle when the trailer not in use can be achieved.

A seat adapter removably mounts a child seat to a wagon having two opposing walls and an interposed connecting wall, and includes two latch components that mount to the wagon's opposing walls. In some embodiments, the seat adapter includes a cross-member extending between the latch components so that the cross-member provides structural integrity to the wagon if the connecting wall is displaced from its upright use position. In some embodiments, the seat adapter and the child seat can be mounted to the wagon for use with the connecting wall in its upright use position, and in some embodiments the seat adapter and the child seat can be mounted to the wagon for use whether the connecting wall is in its upright use position or its displaced position, with no mechanical interference between any part of the wagon and any part of the adapter or the child seat mounted to it.

A foldable wagon is provided that is configurable in a use configuration and folded configuration. The foldable wagon has a front frame assembly, a rear frame assembly, a first upper pivot bracket and a first lower pivot bracket connecting the front frame assembly to the rear frame assembly. The wagon has a timing member to maintain the front and rear frame assemblies synched during folding and unfolding of the wagon. The wagon also has a footrest with a first end connected to the rear frame assembly and a second end free from connection to the front frame assembly. When the second end of the footrest is raised the rear frame assembly and the front frame assembly pivot from the use configuration to the folded configuration. The wagon also has foldable front and rear seatbacks.

Disclosed herein is a folding wagon that is capable of being folded between an expanded open configuration at which a variety of articles or children are carried in a basket of the wagon and a compact collapsed configuration to facilitate storage or transport when the wagon is not being used. A pair of fold-down seats which are carried inside the basket to transport small children are rotatable between a vertically upright position and a horizontally flat position. A handle is pivotally coupled to the front of the wagon and rotatable between a first position lying inside the basket and a second position extending outwardly from the front of the wagon. A handlebar is pivotally coupled to the rear of the wagon and rotatable between a first position extending horizontally outward from the rear of the wagon and a second position extending vertically downward alongside the wagon.

Compactible wagons are provided having at least two operational configurations. The compactible wagon has a first unfolded configuration where the first and second set of wheels are space apart by a horizontal platform, and where the wagon has one or more sidewalls, and at least a second compacted configuration where the horizontal platform is folded into a vertical configuration and the first and second set of wheels are disposed next to each other. The compactible wagon can have one or more additional configurations, including at least an unfolded configuration without sidewalls and/or an extended configuration where one or more of the sidewall are disposed to extend the surface area of the horizontal platform of the wagon. Many different rigid and flexible sidewalls may be used with the wagon.

A beach wagon for transporting water sport boards and smaller objects. The wagon includes a front wall and the rear wall extending vertically from a floor and engaged to side walls; the wagon is carried on a plurality of wheels. The front wall and the rear wall each include a retaining slot. The retaining slots are in substantial alignment to hold a water sport board in the retaining slots spanning between the front wall and the rear wall. The walls of the wagon retain the smaller objects in the wagon. The slotted front and rear walls can be configured to retrofit existing wagons.

A power assist system for a wagon having a safety cut-off system is provided. The power assist system preferably includes a wagon body having a plurality of wheels, at least one of which is a driven wheel, a pivotable handle, a drive system having a motor mechanically connected to the driven wheel, a microcontroller that obtains an input signal and provides an output signal to the drive system and, a safety cut-off system connected to the handle. In one embodiment the safety cut-off system includes a safety-control switch electrically connected to the microcontroller, and the microcontroller adjusts the signal sent to the drive system based on a state of the safety-control switch.

The beach caddy rack insert is an accessory that increases the hauling capacity of a wagon or beach caddy. The beach caddy rack insert may be placed into the wagon and may be retained in place by side walls of the wagon. The beach caddy rack insert may comprise front and rear end sections separated by four detachable longitudinal braces. Cargo may be carried in the wagon by placing the cargo into the wagon between the front end section and the rear end section. Cargo that will not fit into the wagon may be carried by placing the cargo above the wagon on top of the front end section, the rear end section, and/or two of the longitudinal braces. Cargo carried above the wagon may optionally be lashed in place using one or four uprights provided for that purpose.

A folding cart includes a frame body and a handle mechanism. The frame body comprises a chassis, four lower hinged seats at four corners of the chassis, a front folding mechanism in front of the chassis, a rear folding mechanism behind the chassis and two side folding mechanisms on the side of the chassis. A bottom portion of the lower hinged seats is provided with wheels. The chassis is an X-shaped cross-hinged structure and has four end portions respectively hinged to the lower hinged seats. The side folding mechanism has at least one X-shaped cross-hinged rod assembly with upper ends hinged to the upper hinged seats and lower ends hinged to the lower hinged seats. The front folding mechanism and the rear folding mechanism respectively have at least one X-shaped cross-hinged rod assembly having two hinged cross rods.
