Abstract
A collapsing cart for wheeled transport of diverse items over the ground surface. The cart includes a pair of side members having handlebars for grasping by a user and a number of ground-engaging wheels for movement. A number of lateral struts join the side members together. A flexible article carrier is suspended from two of the lateral struts. In the event that the cart is to be used on unconsolidated or uneven surfaces, an auxiliary carriage having load-distributing rollers may be secured beneath the wheels.
Claims15
A cart, comprising:
- first side member having a first handlebar for grasping by a user;
- a second side member having a second handlebar for grasping by a user;
- a plurality of wheels carried on said first and second side members;
- said first and second side members each including:
- a forward leg carrying one of said plurality of wheels;
- a rearward leg hingedly connected to said forward leg and carrying another of said plurality of wheels;
- and,
- a longitudinal strut having opposed ends, one of said ends secured to said forward leg and the other of said ends secured to said rearward leg;
- a plurality of lateral struts joining said first and second side members together, each of said lateral struts including a first arm and a second arm having inner ends hingedly secured together, said first arm having an outer end hingedly secured to said first side member, and said second arm having an outer end secured to said second side member;
- a first strap suspended between said first and second handlebars and connected to each of said lateral struts so that the application of an upward force to said first strap will cause articulated movement of said first and second arms collapsing the cart laterally;
- and,
- a flexible article carrier suspended from two of said plurality of lateral struts and suspended from each of said longitudinal struts.
