HANDHELD PATTERN CREATING DEVICE AND METHOD OF USE OF SAME

摘要

A handheld pattern creating device (10) and method of use of the same are disclosed. In one embodiment, a rotational member (80) is rotatably positio ned within a housing (40) under the power of a first drive mechanism (110) t o angularly traverse an x-y plane. A rail track (82) is disposed on a surfac e (86) of the rotational member (80) in order to provide a radial path (82) for a carriage (112) that houses a tool tip (70). A guide track (94) dispose d on the surface (86) of the rotational member (80) includes a curved portio n (96) that provides a non-linear path (98). A second drive mechanism (118) drives the carriage (112) transversely along the radial path (82) of the rai l track (82) such that a flexible rack gear (120) travels the non-linear pat h (98) of the guide track (94).
