Rim brake for bicycles, with an adjustable distance between the brake shoes and the wheel rim in the rest position

摘要

The so-called cantilever - brake is the most widely used brake for bicycles. This rim brake has a deficiency: even if the brake lever is not actuated, sometimes grinds a brake shoe (1) at the wheel rim (2), even though the brake has been correctly set in front of. This is done in particular when water or dirt penetrates between the parts of the rim brake.Thus the brake shoes (1) in case of a non-actuated rim brake always the same distance from the wheel rim (2), the restoring path of the brake arms (6) limited. In this case, the restoring spring (5) the two brake arms (6) to the setting elements (4). As shown in 3 shown, the rim brake can be constructed so that, the distance between the brake shoe (1) and wheel rim (2) is adjustable in the rest position, with in each case a at the attachment element (13) mounted to the adjusting element (4).Since the described design of the rim brake is oriented at the most widely used type of construction, the adaptation of the existing production process does not have a great effort and expense, in order to convert the invention.
