Abstract
An undercarriage for transporting a stretcher includes a support base, which is adapted for supporting a stretcher, a first pair of legs pivotally mounted to the support base, and a second pair of legs pivotally and slidably mounted to the support base. The first pair of legs is independently pivotal about the support base from the second pair of legs. In addition, a journaled member is provided at the distal ends of each leg. The undercarriage also includes a control system that is adapted to selectively pivot the first pair of legs to a stowed position and to selectively pivot the second pair of legs to a stowed position. The control system is further adapted to selectively lengthen or shorten the legs to adjust the height of the support base.
Claims23
An undercarriage for transporting a stretcher, said undercarriage comprising:
- a support base adapted for supporting a stretcher, said support base having an open compartment and defining an upper plane bounded by an upper surface of said support base and a lower plane bounded by a lower surface of said support base;
- a first pair of legs pivotally mounted to the support base, said first pair of legs comprising forward legs;
- a second pair of legs pivotally and slidably mounted to the support base, said second pair of legs comprising rearward legs, said first pair of legs being independently pivotal about said support base from said second pair of legs;
- a journaled member provided at the distal ends of each leg;
- and
- a control system adapted to selectively pivot said first pair of legs to a stowed position and to selectively pivot said second pair of legs to a stowed position, and said control system further adapted to selectively lengthen or shorten said legs to adjust the height of said support base, said control system including a plurality of actuators, said actuators pivoting and adjusting the length of said legs, and said actuators comprising cylinders.
An undercarriage for transporting a stretcher, said undercarriage comprising:
- a support base adapted for supporting a stretcher, said support base having an open compartment and defining an upper plane bounded by an upper surface of said support base and a lower plane bounded by a lower surface of said support base;
- a first pair of legs pivotally mounted to the support base, said first pair of legs comprising forward legs;
- a second pair of legs pivotally and slidably mounted to the support base, said second pair of legs comprising rearward legs, said first pair of legs being independently pivotal about said support base from said second pair of legs;
- a journaled member provided at the distal ends of each leg;
- and
- a control system adapted to selectively pivot said first pair of legs to a stowed position and to selectively pivot said second pair of legs to a stowed position, and said control system further adapted to selectively lengthen or shorten said legs to adjust the height of said support base, said control system including a plurality of actuators, said actuators pivoting and adjusting the length of said legs, each of said legs including a pivot actuator and a height adjustment actuator wherein said pivoting and said adjusting the length of said legs is independent.
An undercarriage for transporting a stretcher, said undercarriage comprising:
- a support base adapted for supporting a stretcher, said support base having a frame;
- a first pair of legs pivotally mounted to opposed sides of said frame, said first pair of legs comprising forward legs;
- a second pair of legs pivotally and slidably mounted to said frame and being extendible into said frame, said second pair of legs comprising rearward legs, said first pair of legs being independently pivotal about said frame from said second pair of legs;
- a journaled member provided at the distal ends of each leg;
- and
- a control system adapted to selectively pivot said first pair of legs to a stowed position and to selectively pivot said second pair of legs to a stowed position in said frame, said control system including a plurality of actuators, said actuators pivoting said legs, and said actuators comprising hydraulic cylinders.
