Abstract
A collapsible trolley or other transport device includes a body having a back panel, a shelf panel pivotally attached to a bottom edge of the back panel, a pair of back wing panels pivotally attached one each to opposing side edges of the back panel, a pair of shelf wing panels pivotally attached one each to opposing side edges of the shelf panel and a pair of auxiliary panels pivotally attached one each to the pair of shelf wing panels and attached to bottom portions of the pair of back wing panels. The body is movable between an unfolded use configuration and a folded storage configuration. A pair of wheels is attached to the pair of back wing panels and the pair of auxiliary panels by a pair of wheel brackets.

A collapsible trolley comprising;
- a body including:
- i. a back panel;
- ii. a shelf panel pivotally attached to a bottom edge of the back panel;
- iii. a pair of back wing panels pivotally attached one each to opposing side edges of the back panel;
- iv. a pair of shelf wing panels pivotally attached one each to opposing side edges of the shelf panel;
- v. a pair of auxiliary panels pivotally attached one each to the pair of shelf wing panels and attached one each to bottom edges of the pair of shelf wing panels;
- b) said body movable between an unfolded use configuration, where the pair of back wing panels, pair of shelf wing panels and the shelf panel are all generally at an angle of approximately 90° with respect to the back panel so that the pair of back wing panels and the pair of shelf wing panels cooperate to support the shelf panel, and a folded storage configuration where the pair of back wing panels are generally in the same plane as the back panel, the pair of shelf wing panels are generally in the same plane as the shelf panel, the shelf panel overlays a portion of the back panel and the shelf wing panels overlay portions of the back wing panels;
- c) a first wheel;
- d) a first wheel bracket having a first top end portion, a first bottom end portion and a first abutment portion;
- e) a first one of the pair of back wing panels having a first bracket top slot and a first bracket bottom outer opening;
- f) a first one of the pair of auxiliary panels having a first bracket bottom inner opening aligned with the first bracket bottom outer opening;
- g) the first wheel bracket top end portion secured through the first bracket top slot and the first wheel bracket bottom end portion secured through the first bracket bottom outer and inner openings so that the first wheel is rotatably positioned between the first back wing panel and the first abutment portion of the first wheel bracket and the first wheel bracket top end portion is covered by the first one of the pair of auxiliary panels;
- h) a second wheel;
- i) a second wheel bracket having a top end portion, a second bottom end portion and a second abutment portion;
- j) a second one of the pair of back wing panels having a second bracket top slot and a second bracket bottom outer opening;
- k) a second one of the pair of auxiliary panels having a second bracket bottom inner opening aligned with the second bracket bottom outer opening;
- and
- l) the second wheel bracket top end portion secured through the second bracket top slot and the second wheel bracket bottom end portion secured through the second bracket bottom outer and inner openings so that the second wheel is rotatably positioned between the second back wing panel and the second abutment portion of the second wheel bracket and the second wheel bracket top end portion is covered by the second one of the pair of auxiliary panels.
