TooWheels - wheelchair with open documentation



TooWheels (this is a pun, it can also be heard as two wheels) - a wheelchair with open documentation (CC-NC-SA), which can be made independently anywhere, fitting to the required dimensions and materials available in the area. Originally developed as a sport, today it is easily adaptable to other applications thanks to the efforts of users and the community. From India to Ecuador, not to mention Italy, where it all began, a design is being developed that meets the requirements of a wide range of people with disabilities. Many partners also take part in the project, including the Italian Federation of Invasport * . You can download files and documentation and make a wheelchair at home using simple tools or in a workshop with computerized equipment. Make as many details as you can and you can reduce the cost by 10 times. Back in 2016, the project received the Golden Circle, an international award from the Designers Association of Italy.

In the wheelchair Toowheels you can use the materials at hand, such as plywood, pipes, bicycle parts. It is possible to change the sizes and their ratios, having received as a result a design adapted to various applications. Also, as stated above, it is possible to adapt to the materials and parts available in the area. Work is underway to organize local production of wheelchairs in developing countries, which will create jobs for people with disabilities, give them social benefits and an affordable means of transportation.

Advantages of the project:

The ability to fit the size of the user, the use of local materials.

The price is 10 times less than sports wheelchairs with similar characteristics.

Adaptability to various applications: on the same chassis you can make a sports, off-road or urban stroller, making only small changes.

Open documentation: three-dimensional files or drawings can be downloaded from the project site, after which the stroller can be made on computerized equipment, or using ordinary jigsaw, drill, etc.

The project started in 2012, over the years it has been possible to involve people working on it and offering new improvements. Fruitful cooperation helps to find new goals, be ready to solve new problems.
