Definitions

  • the present invention relates to a bed having a raisable back support element.
  • Beds of the type home care beds and hospital beds usually have a raisable back support element which makes it possible for the person using the bed to take a more or less raised position in the bed.
  • a drawback of previously known beds of this kind is that the back support element while being raised displaces the person using the bed towards the foot end of the bed at the same time as the shoulders of the person are subjected to a downwardly directed force. This is dependent on the fact that the mattress increases the thickness of the raisable back support element and that the surface on which the person rests thereby is at a larger distance from the pivot axle of the back support element.
  • the object of the invention is to provide a bed having a raisable back support element wherein the person using the bed is not displaced towards the foot end of the bed when the back support element is raised.
  • the bed according to the invention is characterized in that the back support element is at the portion adjacent the bed framework connected with the bed framework by means of a guiding device for guiding the portion of the back support element adjacent the bed framework towards the head end of the bed when the back support element is raised.
  • the guiding device of the bed according to the invention is in a preferred embodiment thereof adapted to increase the height of the back support element when this is raised in relation to the bed framework.
  • the guiding device comprises an arcuate element which at one end is connected with the portion of the back support element adjacent the bed framework and from the portion connected with the back support element extends arcuately downwards in relation to the lower surface of the back support element and has its opposite end positioned in the plane of the back support element outside the portion of the back support element which is positioned outside the bed framework.
  • the arcuate element is connected with a portion which is firmly connected with the bed framework and which portion engages the arcuate element so as to guide the portion of the back support element adjacent the bed framework against the head end of the bed and perhaps also increase the height of the back support element in relation to the bed framework when the back support element is raised so as to prevent that the shoulders of the person using the bed are subjected to a downwardly directed force.
  • the portion which is firmly connected with the bed framework when the back support element is in lowered position engages the arcuate element adjacent the end thereof connected with the back support element and that the annular element is at the raising of the back support element guided along the portion firmly connected with the bed framework, so that the portion firmly connected with the bed framework in the completely raised position of the back support element engages the opposite end of the arcuate element in relation to the end connected with the back support element.
  • the back support element is connected with the bed framework by means of a raising element for raising the back support element, the raising element being pivotely connected with the bed framework as well as the support element and being positioned below the back support element. It is suitable that the raising element is adapted at the raising of the back support element to be elongated between its pivotable connections with the bed framework and the back support element and the raising element is driven by a motor at the raising and lowering of the back support element.
  • Fig. 1 shows from the side a bed according to the invention having a half-raised back support element.
  • Fig. 2 shows the bed according to Fig. 1 having a completely raised back support element.
  • Fig. 3 shows the bed according to Figs 1 and 2 having a completely lowered back support element.
  • Fig. 4 shows on an enlarged scale the connection between the back support element and the bed framework.
  • the bed shown in Fig. 1 has a bed framework 2 for supporting a mattress, foldable legs 4 and a back support element 6 which is displaceable between a lowered position in which the mattress of the bed is flat and a raised position wherein the person using the bed takes a more or less raised position in the bed.
  • the back support element 6 is shown in a half-raised position.
  • the raising of the back support element 6 is provided by means of a raising element 8 consisting of a pipe shaped element 10 and a rod 12 displaceable therein.
  • the raising element 8 is driven by means of a motor 14 having a worm gear driving a rotatable screw in the pipe shaped element 10, the rotatable screw being connected with the rod 12 in such a way that the rod 12 is displaced out from the pipe shaped element 10 or is moved into the element 10 when the back support element 6 shall be raised or lowered.
  • a motor 14 having a worm gear driving a rotatable screw in the pipe shaped element 10
  • the rotatable screw being connected with the rod 12 in such a way that the rod 12 is displaced out from the pipe shaped element 10 or is moved into the element 10 when the back support element 6 shall be raised or lowered.
  • the back support element 6 is connected with the bed framework 2 by means of two arcuate element 16 positioned at opposite sides of the back support element 6.
  • the arcuate elements are at one end connected with the back support element 6 at the end 20 thereof adjacent the bed framework 2 and are as is more clearly shown in Fig. 4 connected with the bed framework by means of bearings 18.
  • the bearings 18 cooperate with the inner surfaces of the arcuate elements 16 which in section are U-shaped.
  • the bearings 18 are preferably constituted by sliding bearings but can also be constituted by another type of bearings, for example ball bearings.
  • the back support element 6 takes in its completely raised position at the end 20 adjacent the bed framework 2 its largest distance from the foot end and its most upward position in relation to the framework 2.
  • the back support element 6 In the lowered position of the back support element 6 according to Fig. 3 the back support element 6 is in plane with the rest of the lying surface of the bed at the same time as the end 20 of the back support element 6 is closest to the foot end of the bed.
