Bicycle convertible into a cargo cart chassis with telescopic bar folding mechanism and spring clutch

Abstract

The present invention relates to a folding bicycle convertible into a cargo cart. It comprises a folding mechanism consisting of telescopic bars and cam locks arranged on the frame, handlebars, and seat, as well as a quick-release clutch-type mechanism mounted on the rear fork. This mechanism includes a spring, a retractable slider, and guides that allow the rear wheel's position relative to the frame to be adjusted and secured during use. The bicycle's telescopic structure allows its dimensions to be adjusted to the user's height, and it can be converted into a cargo cart by adding a container with straps that attaches to the frame. The invention offers the following technical advantages: functional versatility, reduced space requirements for transport or storage, and improved ergonomics and adaptability.The design allows the same device to be used for personal mobility and light cargo transport, through a mechanical folding and quick coupling system that is simple and safe to operate.
