Backpack

Abstract

The backpack has a cover at the back, two lockable shoulder straps, a trolley handle and trolley wheels. The trolley wheels can be covered by a protective shield that can be pulled out at the rear bottom. The backpack can be opened using a lid. The trolley handle can be pulled out in two stages. A folding shelf with multiple shelves is integrated inside the backpack. The top shelf can be locked in the first stage of the trolley handle. This allows the folding shelf to be expanded vertically and then compressed again to close the backpack lid. 1.1) Unfolded view; 1.2) Front view; 1.3) Left side view; 1.4) Back view; 1.5) Right side view; 1.6) Plan view; 1.7) Bottom view; 1.8) Perspective view; 1.9) Back view; 1.10) Front view; 1.11) Plan view; 1.12) Front view of trolley
