ABSTRACT:
An articulated medical bed for supporting a person in articulated movement is disclosed. The bed comprises a main frame defining a base and an articulated support frame including an upper body section pivotally connected to the base, a seat section pivotally connected to the upper body section and a detachably mounted lower leg section pivotally connected to the seat section. An elongated link member pivotally connects the lower leg section to the base. A glide member is mounted on the seat section and supported for linear movement along the base whereby the seat section is supported for rocking movement about the glide member. A linear actuator is connected to the upper body section for simultaneously actuating the upper body section, seat section and lower leg section in articulated movement. A side rail is supported on the base and includes telescoping inner and outer horizontal rail members extending between vertical rail members. A detent supported on one of the inner horizontal rail members is engagable with a plurality of recesses formed in one of the outer horizontal rail members. Engagement of the detent with one of the recesses locks the inner horizontal rail member relative to the outer horizontal rail member thereby defining a plurality of positive stop positions. The linear actuator is controlled by a control stick supported on the side rail and located within a plane defined by the horizontal and vertical rail members.
