10532662 · 2020-01-14 · ·

An apparatus has a first portion of a magnetic braking system with a first element disposed thereon. The first portion rotates about an axis. The position of the first element is a fixed distance from the axis. A second portion of the magnetic braking system has a second element disposed thereon. A spring biases the rotatable first portion a first distance from the second portion. Upon application of a force to one of the portions, the relative position of the rotatable first portion to the second portion is reduced to a second distance less than the first distance.

The current subject matter describes a device and system including one or more movable arms containing one or more magnets that are caused to move relative to a non-ferrous material by motion of the device to generate eddy currents that cause a braking of the device. Devices of this disclosure may include a wheel with arms having magnets and that move from centrifugal force caused by rotation of the arms within a wheel. The applied braking force is controlled due, in part, to the configuration of the non-ferrous material in which eddy currents are generated. Devices may additionally or alternately include arms with magnets that move relative to a non-ferrous rail when the device moves to generate eddy currents that cause additional braking of the device.
