Abstract
A collapsible cart assembly having a framework with two brackets. The two brackets have first arms, second arms and third arms. A rear leg frame section is rigidly affixed to the first arms. A front leg frame section that is pivotably connected to the second arms. A handle frame section is pivotably connected to the third arms of the brackets. Slides are disposed on the rear leg frame section. A first set of linkages connect the slides to the front leg frame section. A second set of linkages connect the slides to the handle frame section. The slides and linkages move the front leg frame the handle frame between an open configuration and a closed configuration.
Claims19
A collapsible cart assembly that can be selectively configured between an open configuration and a folded configuration, said cart assembly comprising:
- a set of brackets,
- a rear leg section having a first set of frame elements that connect to said set of brackets;
- a front leg section having a second set of frame elements that are pivotably connected to said set of brackets;
- a handle section having a third set of frame elements that are pivotably connected to said set of brackets;
- slides disposed on said first set of frame elements, wherein said slides can reciprocally move along said first set of frame elements;
- linkages that connect said slides to said front leg section and said handle section;
- a locking mechanism that selectively locks at least one of said slides into a fixed position along said first set of frame elements;
- a release cable that extends from said locking mechanism to said handle section, wherein said release cable releases said locking mechanism when pulled in tension;
- a manually operable cable tensioner disposed on said handle section that pulls said cable in tension and releases said locking mechanism, therein enabling said slides to move along said first set of frame elements,
- wherein said slides cause said linkages to configure said cart assembly into said open configuration when said slides are engaged by said locking mechanism, and wherein said slides enable said cart assembly to fold into said folded configuration when not engaged by said locking mechanism.
A collapsible cart assembly that can be selectively configured between an open configuration and a folded configuration, said cart assembly comprising:
- two brackets having first arms, second arms and third arms;
- a rear leg frame section that is rigidly affixed to said first arms of said brackets;
- a front leg frame section that is pivotably connected to said second arms of said brackets;
- a handle frame section that is pivotably connected to said third arms of said brackets;
- slides disposed on said rear leg frame section, wherein said slides are capable of reciprocal movement between a first position and a second position;
- a first set of linkages that connect said slides to said front leg frame section;
- a second set of linkages that connect said slides to said handle frame section;
- wherein said slides move said first set of linkages, said second set of linkages, said front leg frame and said handle frame into said open configuration when said slides move to said first position, and
- wherein said slides move said first set of linkages, said second set of linkages, said front leg frame and said handle frame into said collapsed configuration when said slides move to said second position.
