F16D 3/26 Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence)
Introduced: September 1968
Title
Titles differ between systems:
IPC: Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slideably connected
CPC: Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence)
Full Title
Full titles differ between systems:
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slideably connected
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence)
Of 7 combined children, 5 exist in both systems.
