Definitions

  • the invention relates to a bed as defined in the first part of claim 1.
  • Such a bed is known from EP-A-0 418 415.
  • the bed frame is guided with two adjacent strengthened corners directly along the supporting and guiding device upwardly and downwardly.
  • the bed is lifted, while in the horizontal position, onto the ceiling of the concerning room, for which purpose the supporting and guiding device extends through the entire height of said room.
  • the present invention aims at improving this bed in such a manner that the bed frame may in the non use situation, by making use of the drive means for the height adjustment, be tilted upwardly into a standing position along the supporting and guiding device.
  • the bed frame may, in a situation where it takes or reaches its lower operative horizontal position, be folded away by simply having the drive means continue rotating in the direction corresponding to the descending adjustment movement.
  • the supporting point at the lower end of the arm moves from the vertically extending part of the guiding surface to the sloping part of the same, as a result of which the lever and the frame are caused to make an upward swinging movement around the vertically downwardly moving upper end of the arm.
  • the bed according to the invention is particular suitable for use in nursing homes and may, in a state of non use, be hidden from view within a wall unit, such as is known per se with a conventional foldaway bed.
  • the bracket is formed by a substantially U-shaped carriage, that engages a supporting and guiding column which is attached to the supporting wall in a mid position relative to the supported bed frame side, the supporting lever comprising two parallel arms the upper ends of which are pivotally attached, on opposite sides, to the outer sides of the opposite flanges of the U-shaped carriage.
  • supporting rollers are provided within the space between the two arms of the supporting lever, in a position adjacent the lower end of said lever, said rollers bearing on the front wall of the supporting and guiding column that is functioning as a vertical section of said guiding surface.
  • the bed shown in the drawing has a frame 1 that is provided, in the centre of one (short) side 1a, with a double armed supporting lever 2 extending perpendicularly from the plane of the frame.
  • the two arms 2a of the double armed supporting lever 2 have their upper ends pivotally connected - about pivot pins 3 - to the outer sides of the opposite flanges 4a of a bracket of a carriage 4 that has a substantially U-shaped cross section, the web of which is indicated at 4b.
  • the U-shaped bracket engages a supporting and guiding column 6 that is fixedly attached to a supporting wall 5.
  • a guiding rod 7 that is provided, on its side turned away from the supporting wall 5, with teeth 7a, while the opposite side is smooth.
  • the lower guiding rollers 9 are rotatably mounted on the inwardly projecting ends of the pivot pins 3, by means of which the arms 2a are pivotally connected to the flanges 4a.
  • the guiding roller assembly 8, 9, 8a, 9a described hereinabove allows the bracket 4 and the bed frame carried by it to be vertically moved, under low resistance, along the supporting and guiding column 6.
  • a support roller assembly 11 is provided adjacent the lower end of the supporting lever 2, between the two arms 2a of the latter, said roller assembly bearing, throughout the adjustment trajectory between an upper horizontal operative position (fig. 2) and a lower horizontal operative position (fig. 1), onto the front wall 12 of the supporting and guiding column 6 acting as a vertical guiding surface.
  • At least the guiding rollers of one roller pair of the upper and lower pairs of toothed rollers 8a, 8a and 9a, 9a respectively are coupled by a torsion tube 10, due to which also an excentrically loaded bed frame will remain horizontal and be movable smoothly along the supporting and guiding column 6 without jamming of the bracket 4.
  • the drive means for adjusting the bracket 4 along the supporting and guiding column 6 consists, in a well-known manner (see the above mentioned European patent specification), of an electromotor (not shown) driven vertical screw spindle 13 and a running nut 13a cooperating therewith, the latter being fixedly mounted within the vertical space between the column 6 and a flange 4a of the bracket.
  • the screw spindle 13 extends, like the column 6, downwardly up to near floor level, so that the bracket 4 may move further downwardly along the column 6 beyond its position corresponding with the lower operative position of the bed frame.
  • This continued downward movement causes two auxiliary guiding rollers 14 provided on the outer side of the lower ends of the arms 2a to abut against the upper, downwards sloping guiding surfaces 15a of two auxiliary supports 15 that are provided in the dihedral angle between the supporting wall 15 and the floor.
  • a movement of the auxiliary guiding rollers 14 (which are in a free position when in the adjustment trajectory between the upper and lower operative positions of the frame 1) along the downwards sloping guiding surfaces 15a causes the supporting arm 2 to carry out a anti-clockwise (as seen in fig. 3) swinging movement about the pivot point 3 that is simultaneously moving vertically downwardly, whereby the roller assembly 11 is lifted out of engagement from the vertical guiding surface 12 and the bed frame will be ultimately tilted into a vertical position (fig. 3).
