The 2t BASE.



Some options for the 2T base

This basic prototype at Cambridge shows the carcass/shell mounted on the base with a tilt hinge at the level of the fulcrum.   The base is a standard 5 star.   Greater stability when reclined would be improved if the back 2 legs were extended.   This suggests that the rotation of 360° would need to be reduced to about 60° in the anterior direction.

The post Hospital beds shows a number of beds each with a base of great complexity.

  • For this
  • The hinge would be at the apex of the base.
  • The hinge could be mounted at the fulcrum
  • or at the front edge of the seat-pan.
  • Damping is required to avoid a jolt at the end of range.
  • The base can be narrower or wider than the carcass.
  • The latter is more stable.
  • Consider :-
    • The mounting of the arm-rests, if any.
    • A shelf, shelves.
    • side restraints for a hospital bed.
