Definitions

  • a hospital bed according to the preamble of claim 1 is known from CH-PS 656'065.
  • the height of a mattress frame is adjustable compared to a horizontal base frame.
  • the mattress frame is supported on the head and foot side at the free end of one arm by double-armed levers.
  • the other arms of the levers are connected to each other by a tie rod.
  • the lever on the foot can be swiveled by the lifting motor.
  • the first arm of the lever on the head side is a rod of a four-bar link. It can be blocked by placing a locking lever under it, so that only the foot end sinks when lowering by means of the lifting motor.
  • the tie rod has an elongated hole to bridge the relative movement between the two double-armed levers.
  • the mattress frame needs to be adjusted to a different height, e.g. To start the patient or for massages, the inclination must then be adjusted again.
  • Another sick bed is known from CH-PS 373'142.
  • a crank is provided instead of the lifting motor.
  • the support that connects the mattress frame on the foot side with the double-armed lever can be extended telescopically in several stages, so that the foot end can be raised compared to the head end. Tilting the mattress frame with the foot end down is not provided.
  • a stepless adjustment device which locks in both directions, is known from CH-PS 451'432.
  • the present invention has for its object to design a hospital bed of the type mentioned in such a way that the inclination can be adjusted at different altitudes. This object is achieved by the characterizing features of claim 1.
  • the pivot axis, about which the mattress frame is pivotally mounted is arranged in the vicinity of the center of gravity of the mattress frame with a mattress occupied by an average person.
  • This can be used to adjust the inclination Force can be kept low. A manual adjustment is therefore easily possible.
  • the clamping element blocks the stepless adjustment in both directions of movement.
  • the length of the connecting rod which can be changed against the force of a brake, enables the mattress frame to initially rest on the associated stops on the base frame when the foot is inclined when lowering, and when the lift motor is operated, it is lowered into the horizontal position by telescoping the connecting rod, where the mattress frame rests on the stops at both ends, e.g. for massages.
  • the mattress frame With the lifting motor, the mattress frame can be moved through the limit switch, which is usually installed for this purpose, even when it is tilted until the motor is switched off. When the mattress frame is then lifted, it automatically resumes its previously set inclination. Because the length adjustment of the connecting rod is braked, there are no sudden changes in inclination even when the mattress frame is loaded incorrectly.
  • the bed shown in longitudinal section in FIG. 1 comprises a horizontal base frame 1 and a height-adjustable mattress frame 2.
  • the base frame 1 can be moved on four castors 3.
  • One arm 6 of the first lever 4 on the head side forms the one rod of a four-bar linkage 7.
  • Two of the hinge points 8, 9 of the four-bar linkage 7 can be pivoted on the base frame 1, the link point 8 being formed by a torsionally rigid tube rotatably mounted on the base frame.
  • the rod 12 connecting the two other articulation points 10, 11 of the quadrilateral joint 7 is extended upward above the articulation point 11 and is connected at its free end to the mattress frame 2 in its middle third about a horizontal pivot axis 13.
  • the pivot axis 13 is adjacent to the center of gravity of the mattress frame 2 loaded with a mattress and an average person, but slightly shifted towards the head end.
  • the quadrangle 7 is designed so that when the lever 4 is pivoted, the pivot axis 13 moves approximately in a vertical plane, so that the mattress frame 2 shifts only insignificantly with respect to the base frame 1 during the vertical movement.
  • the second double-armed lever 5 is also attached to the base frame 1 on a rotatable torsion-resistant tube 18 adjacent to the foot end.
  • the free end of its one arm 19 is articulated to a connecting link 20, the other end of which is articulated on the mattress frame 2.
  • the length of the connecting member 20 between its two joints 21, 22 can be adjusted by means of a continuously adjustable clamping member 23 which locks in both directions.
  • the clamping member 23 (FIG. 2) consists of two clamping plates 26 inserted in a housing 24 at the upper end of a carrier 25. A bore 27 of these clamping plates 26 is guided on a rod 28 with play. This rod 28 carries at the upper end a connecting tube acting as the joint 22.
  • the clamping plates 26 are fixed in the longitudinal direction of the rod 28 by three pins 29 which are seated transversely to the longitudinal direction of the rod 28 in the housing 24, in that they are inserted between two of these pins 29 with little play. On one side, the clamping plates 26 are spread apart by a compression spring 30. On the other hand, there is 24 in the housing a torsion bar 31 rotatably mounted. This engages loosely with a flat 32 between the two clamping plates 26. A cable 34 engages a lever 33 connected to the rod 31. Its other end is connected to a handle 35 adjacent to a gripping rod 36. By pulling the handle 35, the rod 31 pivots, so that the two clamping plates 26 are pivoted against the force of the spring 30 and their clamping action is released. The mattress frame can then be pivoted about the axis 13 with the gripping rod 36. Since this axis 13 is arranged adjacent to the center of gravity, the effort for pivoting is small.
  • the two second arms 40, 41 of the double-armed levers 4, 5 are connected to one another at their free end via a telescopic connecting rod 42.
  • This consists of a tube 43 articulated on the free end of the arm 41 and a rod 44 which is longitudinally displaceable in the tube 43 and articulated on the free end of the arm 40.
  • an axial section through the connecting rod 42 is shown enlarged.
  • the rod 44 has an elongated hole 45 through which a pin 46 seated in the tube 43 is inserted.
  • the end of the rod 44 protruding into the tube 43 is tapered onto a cylindrical extension 48 via a conical shoulder 47.
  • a split pin 49 at the end secures a washer 50.
  • a package of is supported against this Disc springs 51 from.
  • the plate spring 52 facing the shoulder 47 is conical opposite the shoulder 47 and presses a plurality of balls 53 against the shoulder 47 and the tube 43. These balls 53 act as a brake 54 against a displacement of the rod 44 in the tube 43, the braking effect being from the direction of displacement depends:
  • the connecting rod 42 is pulled apart, the escaping shoulder 47 exerts a slight braking force on the balls 53 rolling on the tube 43, while these wedge more when the connecting rod 42 is pressed between the tube 43 and the shoulder 47 and brake strongly.
  • the connecting rod is normally in the basic position shown in FIG. 3, in which the pin 46 rests on the end of the elongated hole 45 facing the shoulder 47, because the mattress frame 2 is slightly foot-heavy and therefore the connecting rod 42 is normally subjected to tension.
  • a lifting motor 58 is articulated to the base frame 1. Its lifting rod 59 is articulated on the arm 40. Their stroke is limited in both directions by limit switches, not shown.
  • the mattress frame 2 If the mattress frame 2 is then raised again with the motor 58, it first lifts off the stop 64 and the connecting rod 42 is pulled out again until the pin 46 stops at the end of the elongated hole 45, so that the mattress frame again assumes the previously set inclination.
  • the braking force of the brake 54 is lower, so that a mere slight load on the feet of the mattress frame 2 is sufficient. If the head end is heavily loaded when the mattress frame 2 is raised, the connecting rod 42 telescopes only slowly because of the brake 54, so that there are no abrupt movements of the mattress frame which are unpleasant for the patient.
  • the pivot axis 13 can be placed in the center of gravity of the occupied mattress frame 2 if in the connecting rod 42 an additional compression spring between the free end of the extension 48 and the free end of the tube 43 is excited. In this variant, however, the set inclination is lost when the handle 35 is actuated in the lower limit position of the mattress frame.
