  • the bed ends namely a head end 41 and a base end 43, are formed from steel and each bed end comprises an end wall 47 and sides 49.
  • the mattress platform includes:
  • the frame 10 is formed in two parts 12, 19 which are hinged together by hinge members (not shown) , with the part 12 forming a back rest section which can be raised relative to the other part 19 from a horizontal position to a series of raised positions .
  • the mattress platform further includes a means (not shown) for raising/lowering the back rest section 12 and for raising/lowering the frame 10 into a Trendelenberg position in which the legs and body of a person on the bed are raised relative to the head of the person.
  • the suspension system of the bed enables the mattress platform to be raised and lowered through a range of positions from the dashed outline lowered position to the solid outline raised position shown in Figure 1.
  • a first chain 45 of each pair is attached to an upper mounting point (not shown) of the head end 41 and extends downwardly and under a sprocket wheel 33 and along the length of the beam 11 and over a sprocket wheel 33 (not shown) at the opposite end of the beam 11 and downwardly to a lower mounting point (not shown) of the base end 43 and is attached to that mounting point.
  • a second chain 47 of each pair is attached to a lower mounting point (not shown) of the head end 41 and extends upwardly and over the sprocket wheel 33 and along the length of the beam 11 and under the sprocket wheel 33 (not shown) at the opposite end of the beam 11 and upwardly to an upper mounting point (not shown) of the base end 43 and is attached to that mounting point.
  • the drive means for moving the mattress platform includes an electric motor (not shown) mounted on the head end 41 of the bed.
  • the motor drives a vertically-extending screw 45 which extends through and threadedly engages a nut 46 connected to cross- member 13 of the mattress platform. With this arrangement, rotation of the screw 45 about its vertical axis causes vertical movement of the mattress platform via the nut 46.
  • Each bed includes a guide assembly at each bed end 41, 43 for ensuring smooth vertical movement of the mattress platform when the drive means is actuated.
  • the guide assembly comprises a vertical rail 61 connected to each side 49 of the bed ends 41, 43 and a guide carriage 63 connected to the ends of the elongate beams 11 of the support assembly of the mattress platform.
  • the carriages 63 are constructed with rollers (not shown) for sliding movement along the rails 61.
  • each beam 11 of the support assembly of the mattress platform includes a main beam section 25 and end sections , generally identified by the numeral 27. As is described in more detail below, the end sections 27 and the main beam section 25 are pivotally connected together .
  • Each end section 27 includes parallel side walls 29 that are welded to both the lower and the upper cross- members 13 shown in the figures .
  • a pivot pin 35 extends between and is supported by the side walls 29.
  • one of the sprocket wheels 33 is mounted to and supported by the side walls 29 of the end section 27.
  • Each end of the main beam section 25 includes a side 31 that extends parallel to and inwardly of one of the side walls 29 of the adjacent end section 27.
  • the side 31 includes an opening (not shown) and the side 31 is positioned so that the pivot pin 35 extends through the opening. This arrangement pivotally connects together the end section 27 and the main beam section 25.
  • each bed end 41, 43 and associated end sections 27 are linked together in the sense that each bed end 41, 43 and associated end sections 27 are constrained to pivot together as a unit relative to the main beam section 25 between the operational position shown in Figure 3 and the transport position shown in Figure 4.
  • the bed also includes reaction surfaces that contact the chains 45, 47 as the bed ends 41, 43 and associated end sections 27 are being folded from the operational position to the transport position and maintain the tension of the chains 45, 47.
  • the reaction surfaces include an outer sleeve 71 of each pivot pin 35 which is positioned to contact the first chain 45 and an extension 73 of the top wall of the main beam section 25 which is positioned to contact the second chain 47 during pivoting movement of the bed ends 41, 43 and associated end sections 27 onto the mattress platform.
