Definitions

  • the present invention relates to a nursing bed, which comprises a frame, legs fixed to the frame, one or several adjusting devices for moving the frame or a part connected to it in vertical direction of the bed and/or for moving the frame or a part connected to it into inclined position as well as a power device for driving the controlling device.
  • Beds are usually used as lying and resting platforms in homes, nursing homes, hospitals and, in general, in places where people need to rest.
  • Standard models of beds are known where there is a frame or a framework, legs fixed to it and possibly ends.
  • various more specialized solutions in which, apart from the earlier mentioned parts, there are constructions and functions, among other things, for adjusting the height of the bed and/or the bed plane, for adjusting, inclining the back rest position and/or other parts of the bed.
  • Nursing beds are in use in various kinds of nursing institutions such as hospitals, nursing homes, old people's homes and so on. Elderly people, patients and/or other people who, for one reason or the other, are not able to move by themselves are taken care of in nursing beds. Therefore, nursing beds must be able to be lowered and lifted to various heights as well as adjusted in other ways.
  • nursing beds comprise ends, side rails and other necessary functions and accessories, which may be adjusted in different ways for facilitating the nursing of a patient.
  • a nursing bed comprises a lower frame and an upper frame and a motor between them to adjust the upper frame with respect to the lower frame.
  • the object of the invention is to provide a nursing bed with which the problems related to recognized nursing beds are eliminated.
  • the object of the invention is to provide a nursing bed, which is simple by construction and economical by manufacturing costs, but which is easy to use and which has versatile adjusting possibilities.
  • the object of the invention is accomplished by a nursing bed, the characteristics of which are presented in the claims.
  • the frame of the nursing bed in accordance with the invention comprises two parts, which are adjusted turnable to each other by a joint.
  • the nursing bed comprises an adjusting device connected with gliding elements to the parts and the legs of the bed in order to adjust the mutual position of the parts of the frame with the leg of the upper frame and to adjust the height of the nursing bed, in which case the turning angle of the leg of the upper frame while the back rest turns is more than 90 degrees.
  • adjusting devices advantageously with a spindle, placed in both frame parts connected to the parts of the frame and with gliding bricks straight to the legs, mutual positions of frame parts as well as the height of the nursing bed may be adjusted.
  • the part of the frame acting as a backrest turns by changing the angle of the transverse central joint and by adjusting the position of legs.
  • the frame is functioning at the same time as the legs, there is no need for a separate framework and therefore the construction is simpler.
  • both parts of the frame have their own adjusting device, in which case the positions of the legs may be adjusted separately. Since the legs may be separately adjusted, it makes it possible to have a large adjusting range in terms of height as well as when lifting the backrest.
  • the nursing bed Due to its large range of adjusting, the nursing bed is suitable, for example, for nursing homes, old people's homes, and, in general, for places where beds with versatile functions are required. There is only one power motor in the nursing bed in accordance with the invention, with which all functions may be driven. Due to its construction, the nursing bed has very low initial height and high possible lifting height. In addition, the nursing bed is possible to be adjusted to several various positions easily and without effort.
  • the central point of the turning radius of side rails is placed in the middle of the turning point of the frame parts and the opposite parts of the side rails are compatible along the radius as to their curved shape, in which case the distance between the side rails does not change in connection with mutual moving of the frames.

  • the joint parts 21 of the adjusting frame are formed of plate-like parts placed at a suitable distance from each other and a transverse peg and they make it possible for the hook like joint parts 22 of the side rail to function as locking and opening.
  • the side rail 18 may be turned away from its place by lifting slightly and turning outwards on the pegs placed in joints.
  • the spring handle lock 23, placed in the other joint of the lower side rail, is non-central by adjusting.
  • the side rails shown in figure are compatible due to their curved shape 24 and are compatible with the transverse turning middle line of the frame, in which case the distance between the sides remains the same while moving the backrest of the bed.
  • Figure 3 illustrates the gliding bricks 25 and 26 functioning as gliding parts which are connected to the legs 3 and 4 of the nursing bed and two other gliding bricks 27 and 28, which are reserved for possibly adjusting leg parts and/or lifting device.

  • the other end is controlled by an adjusting brick 48, illustrated in figure 3, moving inside a transverse square tube, which adjusting brick has a shaped groove guiding the end of the rocker switch and cogging on sides, by means of which the cogs of the wheel of the controlling motor transmit the motion.
  • the controlling unit converts the commands from the driving brick to functioning commands, which are controlled and limited by switches.
  • the controlling motor and the gliding brick convert electrical commands into mechanical movements for switches.
  • Power transmission between the lower and the upper frame is carried out with a pair of wheels, in which there is an outer wheel 39 connected to the lower frame and a smaller plate cogwheel 41 connected to the upper frame (figure 1). Power transmission is carried out as a mutual function of the rim, formed by the peg like teeth 40 of the outer wheel 39 placed in the direction of the middle line and the smaller plate cogwheel 41 placed inside them.
  • the pitch circle rim 42 of both cogwheels is placed in the upper edge at the same point with the turning point of the frame, which makes the changing of their mutual angle possible during rotating.
  • the leg part 98 of the lifting device in accordance with figure 12 has been attached to the transverse beam 9 in the lower frame (figure 1), which beam is placed inside the shaped tube 99 reaching backwards.
  • At the end of the arm there is a folding wheel 101 and a lifting cloth 102, the other end of which has been attached to a lifting aid or similar by means of a connecting part 103.
  • the other end of it 104 has been attached to the gliding brick 28 of the spindle of the third profile 2c of the lower frame of the nursing bed (figure 1) and goes through advantageous guiding points, through the foot part 98 of the lower end and the hollow crane arm 100 down at the point of the folding wheel 101.
