Rotary brake lever for bicycles

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a rotary brake grip for bicycles, in which the brake mechanism is at least partially integrated into the handlebar. By twisting the grip at the handlebar end, the brake cable inside the handlebar is tensioned, activating the brake. The design includes components to guide the brake cable and prevent unintended movement of the grip.

Use CasesContent extracted from patent full text and abstract with AI.

• Bicycles requiring alternative or integrated brake control mechanisms
• Folding or compact bicycles where space-saving brake designs are needed
• Electric bikes or e-scooters seeking a streamlined handlebar with integrated controls
• Adaptive cycles for riders with disabilities or reduced hand mobility
• Kids' bikes to provide ergonomic and easy-to-use braking solutions

BenefitsContent extracted from patent full text and abstract with AI.

• Space-saving integration of the brake into the handlebar
• Improved ergonomics and ease of use by enabling braking with a twist motion
• Cleaner bicycle design with hidden cables and components
• Reduced risk of accidental cable movement or misalignment
• Potential for safer and more reliable braking due to secure fixation and guidance of the cable

Patent Abstract

The invention relates to a braking device (BV) for bicycles, comprising at least:- a handlebar tube (1), in which the braking device (BV) is at least partially integrated,- a handlebar end stop (6) fixed in the handlebar tube (1),- a brake cable (8) guided in the handlebar tube (1),- a handlebar cone (7) for rotational guidance of the brake cable (8) guided in the handlebar tube (1), and- a grip body (2) fixed on a sliding bearing sleeve (3), wherein the end piece (2') of the grip body (2) directed toward the handlebar end (1') serves as a cable receiver (2.4) for the brake cable (8), and- its end piece (8') is fixed in a position offset to the z-axis (z) of the handlebar tube (1), wherein- the end piece (8') of the brake cable (8) is adjusted by clamping a grip shield (4) on the end piece (2') of the grip body (2), while- a clamping ring (5) attached to the outside (1") of the handlebar tube (1) and directed toward the handlebar center (LM) prevents horizontal displacement of the grip body (2).
