Self-supporting, environmentally friendly two-wheeled body (bicycle frame) and lightweight components made of reinforced corrugated cardboard and / or honeycomb cardboard

摘要

The object of the invention is to find an environmentally friendly replacement for today's heavy metal frame of bicycles. In today's constructions, the raw material production and the production of the parts, as well as the transport require considerable energy expenditure and complicated operations. The appearance of the bike should be improved by the body. The body material should also be able to find application for lightweight components in other areas. The solution to the problem is first to develop material made of multi-layer, reinforced corrugated cardboard and / or honeycomb cardboard, which is stable and protected against ingestion of humidity, impact resistant and waterproof. The two-wheeled body consists of at least two, essentially mirror-symmetrical shells, which are reinforced by frame-like elements and stably assembled by highly stressable connecting parts that can accommodate technical parts, such as bottom bracket, etc. The body shell can accommodate all the technical parts of a bicycle. Other lightweight components get the desired shape. The invention protects the environment through the use of renewable raw materials and environmentally friendly production. It provides weather and theft protection for the technical parts and many ways to improve the appearance of the bike. For lightweight components in other technical areas, the focus is on environmental protection through the use of renewable and recyclable raw materials and the lower transport weight.
