An obstetric bed comprising a base and a support structure on top of the base for supporting a patient. The support structure has a body section secured to the base in a generally horizontal position, a head section pivoted to the head end of the body section for swinging between a first position in which it extends horizontally outwardly from the body section and a second position in which it is inclined with respect to the body section, and a foot section pivoted to the foot end of the body section for swinging between a first position in which it extends horizontally outwardly from the body section and a second position in which it extends vertically down from the body section at the foot end of the base. Mechanism is provided for holding the head and foot sections in various positions of adjustment.

An obstetric bed comprising: a base, a support structure on top of the base for supporting a patient, the support structure having a body section secured to the base in generally horizontal position, a head section pivotally connected to one end of the body section constituting its head end for swinging on the body section about an axis extending transversely of the support structure between a first position in which it extends generally horizontally outwardly from the body section and a second position in which it is inclined upwardly with respect to the body section, and a foot section pivotally connected to the other end of the body section constituting its foot end for swinging on the body section about an axis extending transversely of the support structure between a first position in which the foot section extends generally horizontally outwardly from the body section beyond one end of the base constituting the foot end of the base and a second position in which it extends generally vertically downwardly from the body section at the foot end of the base, means for holding the head section in its inclined position and in selected positions of adjustment between its inclined and horizontal positions, and means for swinging the foot section between its horizontal and vertical positions and for holding it in selected positions of adjustment therebetween, said swinging and holding means comprising a pin mounted on the base for rotation about the axis of the pin, the latter extending transversely with respect to the base, a linkage connected at one end to the foot section and at its other end, constituting its base end, to said pin for rotation of the base end of the linkage and said pin about said pin axis, and means for rotating the base end of the linkage about said pin axis whereby on rotation in one direction the foot section is raised toward its horizontal position and on rotation in the other direction the foot section is lowered toward its vertical position, said rotating means comprising a screw shaft mounted on the base at the foot end of the base for rotation about its longitudinal axis, said shaft lying in a generally vertical plane extending generally longitudinally of the base, a nut threaded on the screw shaft, and a link pinned at one end to the nut and rigidly secured at its other end to said pin whereby rotation of the screw shaft about its axis effects travel of the nut along the shaft to rotate the link, the pin and the base end of the linkage about the axis of the pin for swinging the foot section between its vertical and horizontal positions.
