HANDHELD DEVICES AND RELATED METHODS

摘要

The invention relates to devices including rotary units and rotary mechanisms that are suitable for use in numerous applications. Rotary units typically include rotational components that are configured to rotate. In some embodiments, for example, multiple rotary units are assembled in rotary mechanisms such that neighboring pairs of rotational components counter-rotate or contra-rotate relative to one another during operation of the rotary mechanisms. Rotational components generally include one or more implements that are structured to perform or effect one or more types of work as the rotational components rotate relative to one another in a given rotary mechanism. In certain embodiments, implements are configured to rotate and/or to effect the movement of other components as rotational components rotate.

主权项

1. A handheld device, comprising:
a head portion comprising at least one rotary mechanism that comprises at least two rotational components, wherein at least a first rotational component is configured to rotate at least partially around a first rotational axis, wherein at least a second rotational component is configured to rotate at least partially around a second rotational axis, and wherein at least one of the rotational components comprises at least one surface that is configured to rotate substantially perpendicular to the at least one of rotational axes, which surface comprises at least one implement; at least one drive mechanism component or portion thereof that operably engages, or is configured to operably engage, at least the rotary mechanism, which drive mechanism component or portion thereof is configured to effect rotation of at least the first rotational component at least partially around the first rotational axis in a first direction and the second rotational component at least partially around the second rotational axis in a second direction; and, a handle portion operably connected or connectable to the head portion.
