A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two support plates are slidably guided on the support base toward and away from each other. A pair of wheel assemblies is provided, wherein a wheel assembly is mounted to an end of each of the support plates remote from the other support plate such that a distance between the wheel assemblies varies with movement of the support plates on the support base. A pair of drive links is provided wherein a drive link is joined to each of the support plates. A drive mechanism is joined to the drive links and configured to selectively move the support plates toward or away from each other.

A transportable fold-out structure includes a support frame. First and second primary platforms are pivotally supported by the support frame and each is disposed in an upright position wherein the platform extends upwardly. Two wall assemblies are disposed opposite each other. Each wall assembly includes a plurality of wall segments joined together. Each wall segment is pivotally joined to the support frame or one of the primary platforms. Each wall assembly is movable from a first position wherein the wall assembly is lying above the first and second primary platforms to a second position wherein the two wall assemblies face each other. First and second extensions are configured to be selectively positionable wherein a first portion of the extension is connected to the support frame and a second portion of the extension is remote from the corresponding first portion and extends laterally from the support frame.

This sliding accessory includes an elongated baseplate for sliding on snow, presenting opposite sides and a shoe, removably attached to a stroller wheel. The shoe defines a housing receiving a lower wheel portion, open toward the top and fixedly delimited by a bottom wall, and by two parallel side walls facing one another. Each side wall has a relief projecting toward the other. The reliefs cooperate by contact with the tire so as, by relative displacement between the accessory and the wheel, to pass the accessory between an operational configuration wherein the reliefs press the tire against the bottom wall to wedge part of the tire in the lower part of the housing to secure the sliding accessory to the wheel, and an inoperative configuration wherein the accessory disengages from the wheel, the tire being elastically compressed by the reliefs as the accessory passes between the two configurations.

Devices, systems and methods for converting wheeled carriers into sliding carriers include at least one sliding member positioned under at least one wheel of a wheeled carrier such as a wagon. The sliding member includes an abutment against which the wheel rests such that when the wheeled carrier is in motion, namely pushed or pulled, the abutment is likewise pushed or pulled, thereby retaining the sliding member(s) under the wheel(s) and transporting the wheeled carrier without significant wheel rotation. In this manner a wheeled carrier can slide on loose terrain such as sand. The device can also be used to slide objects other than wheeled carriers.

A skid including an upper surface having a concave shape running from a leading edge to a trailing edge and a lower surface having a convex shape running from the leading edge to the trailing edge. A storage compartment having a pair of wheels and an upstanding handle rolls onto the upper surface of the skid. The skid aids in transporting the storage compartment across sand or snow.
