Get to know Zipper and its usage
  • Allows you speed along surfaces much faster than “crutching”
  • Comfort for your leg during travel
  • Stairs won’t stop you as with a typical knee scooter, just fold up and use it in standard stair crutch mode
  • Base wheels are locked automatically when you fold to crutch mode for traversing stairs, entering cars, buses, trains in crutch mode.
  • When in crutch mode check with airlines on storage of a typical crutch during flights, it’s about 48.5” long when in down position. Ask the flight attendant or airline if they can store your crutch on board.

With typical crutches you’d struggle and work hard to keep up with others walking. With the zipper you’d scoot with ease with others walking hard to keep up with you. And stairs won’t stop you either.
We call it Zipper, the rolling crutch.

What is Zipper

The product we are introducing is a “Rolling Crutch” which we call the “Zipper”. It’s a device designed as a combination of a typical crutch and knee walker, or knee scooter as they are frequently called.
The purpose of knee walkers is to allow those with temporary or permanent lower leg or foot injuries to get around without the slow use of crutches. However, the one main drawback to these devices realized when the user approaches up or down stairways, escalators, or elevators.
We put our experience and expertise to use and Engineered a solution to this by devising a knee walker which transforms into a crutch for use on stairs or difficult terrane where a typical knee crutch can’t be used.
