ABSTRACT:
A foldable cane constructed in three sections each joined by pairs of hinge links having laterally displaced hinge pins which permit adjoining sections to be swung through 180.degree. relative to each other so that in the folded configuration of the cane the three sections are disposed along side each other in essentially parallel relationship to occupy a minimum amount of space. The pairs of hinge links are equipped with spring urged slidable locking sleeves for locking the hinge links in axial alignment when the cane is in use. The hinge links of each pair further include a cam on one of the links for camming the locking sleeve on the other link out of locking position temporarily when the cane is erected by bringing the sections into alignment with the cam fitting into a cut away portion on the other hinge link for axial alignment of the links and a protuberance on the cam link fitting in a recess in the other link to help prevent lateral displacement or twisting out of axial alignment by external forces when in use.
