Abstract
A frame for holding a body which lies thereon is pivoted on a transverse horizontal axis supported by a couple of vertical parallel uprights, on one of which a fixed electrical device having a rectilinear vertical stroke is provided. The remote controlled driver causes its push rod to move up and down, said push rod being connected with a slider that moves along the uprights. A connection rod is hinged to the slider at one end, and to the frame at the other end, so as to cause the rotation of the frame through an arch in clockwise or counterclockwise direction, depending on slider motion direction.
Claims4
A tilting bed for a patient performing physical therapies, such as muscular restoration, in particular with respect to abdominal and dorsal muscles, comprising:
- a frame supporting a padded plate to receive the patient, said frame being pivotally supported for tilting about a transverse center tilting axis of said bed by two pairs of opposed stationary supporting uprights, the uprights of each pair being vertically and parallelly spaced apart from one another, and being parallel to a longitudinal center plane of the bed, so as to define therebetween a vertical sliding race, the tilting of said frame with the padded plate being performed by an electromechanical device, wherein the electromechanical device comprises:
- an electrical actuator having a vertically reciprocating sliding rod, said rod being moved up and down by said actuator, said actuator being fixedly mounted on the outer side of one pair of the uprights, near the upper ends of said one pair of the uprights;
- a vertically sliding bracket member, comprising a wheeled bracket having a horizontal L-shaped cross section and having two vertical flanges, one of said flanges being disposed perpendicular to the longitudinal center plane of the bed and the other of said flanges carrying parallel horizontal shafts of at least two wheels slidably mounted in said sliding race defined between the uprights, said bracket being connected to the lower end of the reciprocating sliding rod of the actuator;
- and
- a connecting bar pivotally connected at its lower end to the other flange of the bracket, said other flange of the bracket being disposed parallel to the longitudinal center plane of the bed, the upper end of the bar being pivotally connected at a corresponding side of the frame, at a point spaced apart from the tilting axis of said frame by such distance so as to cause the frame with the padded plate to be rotatable about said tilting axis of the frame by an angle of about 120.degree. with respect of the stationary pairs of supporting uprights.
