The HipStar can be transported like a BACKPACK using the shoulder straps attached to the back frame. This makes it easy to travel over more difficult obstacles (rivers, ravines, steps, etc.) or when moving on rough terrain that the cart cannot traverse. For short trips, the handles, pull rods, and wheels can be left in place without collapsing the device entirely. For longer trips, the handles and pull rods can be pulled back and conveniently stored to prevent any interference.
The HipStar’s CART MODE allows for heavy gear to roll with ease over many types of uneven terrain. When used in cart mode, the load is supported mainly by the cart instead of the user who has to only apply lateral motion to move the cart. This clever design factor significantly decreases the stress on the user body and spine during transport. The cart-user attachment is very lightweight and simple to use, and allows for three full degrees of free movement with no resistance when changing directions.
The angle between handles and frame can be adjusted, so the HipStar accommodates a wide range of weights, and by keeping a bag’s CG not only above but slightly ahead of the wheel axle, the HipStar's overall stability is increased. It eliminates pushback force created while walking or running that would overturn the cart. As a result, a bag’s weight is supported almost entirely by the frame with wheels, and the user applies only the pulling force to generate movement. Combined, both the unique placement of the center of gravity and the HipStar's harness make it nearly impossible for the cart to turn over.
Another important distinction is in the HARNESS DESIGN and the ability of the frame to amortize the inertial pushes and pulls related to walking or running, allowing the user to pull the cart smoothly with no body restraint. The upper design allows the user to adjust to fit based on height. The handle-strut angle is also adjustable depending on the load weight, harness height (waist height), and distance from feet to wheels, all of which assist in relieving the stress from the load, allowing the user to walk or run without interference from the cart. The harness (consisting of an adjustable belt and straps) and the two-way shock absorber rods minimize the uneven inertia generated by the user when walking or running, allowing for smooth movement, further reducing stress and minimizing user effort and exertion.
Brakes would slow down or stop HipStar in case of going downhill, or any unpredictable movement or falling.
construction material (aluminum or carbon) and strong joints and connecting links increase durability.
Makes it easy to collapse and assemble. LARGE WHEELS include bearings and shock absorbers that absorb uneven terrain (optional low-pressure tires available).
Between the frame and the handles absorb the pushing force of the equipment while walking or running.
That adjust for distance from the back of the legs to the stabilizer and harness, which prevents disturbing the movement of walking and running (hitting the heels).
Allows users to adjust the width and grip length.
Attachment that mounts the cart to the body at the waist.
With various types/sizes of bags and backpacks.
That adjusts for height and angle between frame and handles, depending on the weight of the equipment (reducing the pressure on the body in the place of mounting).
