Roller braking apparatus e.g. for in-line roller skates, skateboards, uses hand-held release device to provide braking signals for compressed air brake control using wireless communication

摘要

A compressed air brake (20), connected to several rollers (11-15), is connected to a controller (30) and includes flat cylinders (26) or bellows receiving compressed air or gas from a cartridge (22) equipped with a residual pressure display element (24). The controller receives braking signals from a hand-held, pushbutton-activated release device via wireless communication, and operates the air brake using the signals.
