Abstract |
AB |
[EN] A rotary joint, especially for a prosthesis, e.g. to allow a user to assume the lotus position, as a pair of relatively rotating parts including an outer part and an inner part braced at coaxial bosses by tapered rollers forming a play-eliminating tapered roller bearing. An inclined roller bearing is provided between outer peripheries of disk portions of these parts. A housing enclosing the parts contains a locking device in which a locking element is spring biased to engage the parts with teeth of the locking element engaging in teeth of the two parts. A push-button can be depressed to retract the locking element and permit relative rotation. |
