Patent application, filed 15 Dec 98

Pagination or Media Count:
A ball lock mechanism has a shaft with an annular groove formed therearound. A first sleeve fitted on the shaft defines at least one channel between the first sleeve and the shaft. An opening facing away from the shaft is formed at the end of each channel. Ball bearings fill each channel so that, when the channels and annular groove are misaligned, one of the bearings extends partially through each channels opening. A second sleeve is fitted over the first sleeve and the openings for retaining the bearings in the channels. The second sleeve is configured and movable with respect to the first sleeve to push the one bearing extending partially through each channels opening into the channel when the channels and annular groove are aligned. As a result, another of the bearings is pushed into the annular groove while remaining partially in each channel to inhibit axial movement of the shaft relative to the first sleeve.
