Definitions

  • An adjustable bed including a chassis, a bed frame disposed on the chassis, two or three hydraulic cylinder and piston units disposed at the ends of the bed, an articulated connection between the cylinder and piston unit and the bed frame so that the bed frame may be moved to various elevated and/ or inclined positions.
  • the invention relates to an adjustable bed having a frame carried on a chassis and displaceable with respect thereto.
  • the invention consists in an adjustable bed comprising a chassis, a bed frame disposed on the chassis, a cylinder and piston unit disposed on the chassis at each end of the bed, means articulatedly connecting the cylinder and piston units to the bed frame so that the bed frame may be moved to various elevated and/or inclined positions.
  • a pair of cylinder and piston units are provided at one end of the bed spaced from one another.
  • the cylinder and piston units are articulatedly connected to the chassis.
  • Manipulation is simplified by a central switch control.
  • the bed-frame may be made to assume extreme positions for particular treatments. This is very important in case of sudden complications or in case of shock.
  • an actuating cylinder driven by "ice a hand-pump or foot pump may operate the piston cylinder unit or an electro-hydraulic unit will be equally effective, in which case an electric switch may be used to actuate the device.
  • a reversing means for diverting the pressurized liquid will be provided, which enables individual or co-operating actuation of the cylinder and piston units to be carried out, depending on whether horizontal or inclining of the bed frame is desired.
  • both units may be provided with pneumatic springs, preferably with an internal control therefor.
  • the internal control of the pneumatic system ensures mechanically effective retention of the piston of the cylinder and piston unit in any given position of the bed-frame and it thus becomes unnecessary to build in rest-supports.
  • Such a pneumatic system exhibits force (equalizing) energy storage capacity, and jerkless adjustment by hand.
  • the bed-frame is connected to the cylinder and piston units by a transverse support beam disposed at each side by a supporting strap along the bed-frame.
  • two cylinder and piston units may be incorporated at the head or foot of the bed, if desired.
  • This has the advantage of balancing power needs during adjustment, and maintaining equilibrium of the bed frame.
  • the transverse support beam thereon has at its central region a broad attachment-hinge.
  • the cylinder and piston units may be individually or co-operatively controlled and they may be fixed to a transverse support beam on the bed-frame or the undercarriage either coupled together or spaced apart.
  • the cylinder and piston units may be additionally provided with guidescissors (Nuremberg scissors) preferably above the transverse support beams of the undercarriage.
  • two cylinder and piston units are arranged at the head of the bed and only one cylinder and piston unit is at the foot.
  • the simplification of the undercarriage and absence of a fourth castor results in a considerable saving which more than compensates for the extra cost of an additional jack.
  • the bed moreover, becomes easier to move and easier to control when being moved.
  • the improved weight distribution makes it possible for the two cylinder and piston units to be of lighter construction and require less power.
  • the cylinder and piston units are preferably quadrangular or multi-angular in cross-section.
  • FIG. 1 shows a side elevation of an adjustable bed according to the invention
  • FIG. 2 shows a front elevation of the adjustable bed shown in FIG. 1;
  • FIG. 3 shows the adjustable bed shown in FIG. 1 in which the bed frame is elevated at both the head and foot of the bed.
  • FIG. 4 shows the side elevation of FIG. 1 wherein the bed frame is inclined and the head of the bed is elevated and the foot of the bed is in its lowered position;
  • FIG. 5 shows a plan view of the chassis of the adjustable bed shown in FIG. 1 in which additional cylinder and piston unit is provided at the head of the bed.
