The present invention concerns a compactable transportation trolley comprising a support frame comprising
- a first and a second extensible straight elements
- a base portion (9) coupled to two caster wheels
- a trailering or carrying element (10), connectable to said first and said second extensible straight element
said frame being articulated between a first extended configuration and a second compacted configuration, wherein in said extended configuration said frame is substantially presented in a triangular shape, said first and second extensible straight elements substantially being the sides of said triangle and said base portion (9) the basis of this triangle wherein said first and second extensible straight elements respectively comprise a first and a second group of collapsible tubular elements (1-8), in such a way to reduce the volume when in compacted configuration and being an end of said first and of said second extensible straight element articulated to said base portion and the opposite end coupled to said trailering or carrying element (10), said base portion (9) being an axle of fixed length which connects said caster wheels. The two extreme elements of said extensible straight elements coupled with said base portion (9) are articulated by hinge members to said base portion (9) in such a way to allow a rotation of at least one of those two elements on the plane of said base portion (9) |
