Abstract
A mechanical two-way controlled band brake has components, such as a lever, a yoke having arms and a guiding bar, a brake band, anchoring points, pivots and brake drums, which are preferably made of metal or metal alloys. The components of the mechanical two-way controlled band brake may be also made of other materials, such as plastics, combination of metal alloys and plastics or any other materials, which are firm with sufficient bearing capacity.

A mechanical two-way band brake for a caster comprising:
- a vertical axis pivot,
- a control member,
- a fork, and
- a lever that bears on a yoke at least on one end of the lever, whereas the yoke comprises at least one anchoring point on at least one arm of the yoke and is coupled to the fork, whereas the anchoring point is supported by a support of the fork and simultaneously located in a yoke slot of a guiding bar, whereas the yoke is supported free on the support of the fork and in parallel is supported by a spring, whereas in addition the yoke comprises ends and the at least one anchoring point comprises at least one anchoring point at each of the ends of the yoke to fix a brake band to the yoke, wherein the brake band encircles a brake drum of the caster in spiral.
A method of braking a two way band brake the method comprising the step of:
- releasing a lever releases a yoke by which position of the yoke changes and a brake band shrinks around a brake drum, whereas change of the yoke depends on a direction of rotation of the brake drum of a caster.
A method of braking a two way band brake the method comprising the step of;
- pressing a lever onto a yoke presses a spring and at least two anchoring points bear onto a support of the yoke, whereas a brake band releases around a brake drum and releasing of the brake drum enables free rotation of a caster.
