## Abstract

The trolley comprises a pair of sides in a plastic material provided with a through hole for inserting and separably snap-locking a support shaft for a pair of wheels and upper housings for inserting and separably snap-locking respective ends of a tubular metal element, bent into a U shape, which forms a handle for manoeuvring the trolley. The tubular element is mechanically restrained at a variable height to an attachment ring for a collection bag. The trolley also comprises a tray in a plastic material designed to act as a base for supporting the trolley on the ground and as an element for supporting the base of the bag. The tray is fitted with projections which can be inserted and separably snap-locked in lower housings of the sides of the trolley and means for its separable snap-hooking to the shape for supporting the wheels.

## Claims
