Hand Carts With Multiple Axes TRIZ Cases
- Dynamic Triangular Support Folding Cart for Heavy Loads
Sliding upright rods form a dynamic triangular support that distributes loads and simplifies folding on a heavy-duty cart.
- Folding Trolley Frame With Rotatable Linkages for Stable Loads
Rotatable transverse tubes and linkages help the trolley frame fold compactly while improving bottom stability and load capacity.
- Double-Decker Wagon With Separate Decks for Compact Folding
Separate upper and lower decks classify items for easier retrieval, while the folding arrangement reduces the wagon’s folded volume.
- Collapsible Maintenance Cart for Compact Wall and Ceiling Access
An adjustable upper structure expands a compact maintenance cart for wall and ceiling work while air filtration limits contaminant exposure.
- Double-Decker Folding Wagon for Compact Storage and Easy Access
Separate upper and lower decks organize items while folding side mechanisms reduce the wagon’s folded volume for easier storage.
- Double-Handle Shopping Cart for Taller and Shorter Shoppers
A second pair of lower rear handles helps shorter shoppers use the cart comfortably while retaining the upper handle for taller users.
- Storable Pull Handle Assembly for Space-Saving Cart Operation
A guide rail, slide block, and pivoting grip let the cart handle retract below the frame, reducing space during infant or cargo handling.
