초록 ▼

In a platform-carried carpet-cleaning machine for facilitating transport of the machine, the platform including a machine-supporting base having upper surface extending between an open entry-end and a closed back-end, the upper surface having an entry portion sloping at no more than about 5° with respect to horizontal such that the machine can be driven on and off the platform with application of about the same amount of user force as during carpet-cleaning operations. Inner surfaces of first and second platform sidewalls both include protrusions frictionally engaging the machine side panels and configured to sandwich the machine therebetween to prevent lateral movement of the machine on the platform. A pair of wheels is mounted with respect to the base for rolling the machine on the platform across a floor, each wheel being secured to its corresponding sidewall by an axle which extends therethrough and is molded in place through the sidewalls to facilitate assembly of the platform. At least one skid-resisting projection extends from the lower surface to hold the platform from unintended backward rolling when the machine is driven onto the platform.
