Definitions

  • the invention relates to a hospital bed with a lying surface consisting of a backrest, a middle part and a lower leg rest, with axes of rotation lying in a horizontal plane for the backrest and for the lower leg rest and articulated axes between the backrest and the middle part and the middle part and the lower leg rest lie and move in the space between the axes of rotation and with two telescopic supports which are articulated at one end to the middle part and at the other end to the backrest or lower leg rest and can be actuated via a handle.
  • the lower leg rest and the back rest can only be adjusted independently of one another.
  • a transport chair in which the lying surface is formed from a lower leg rest, a middle part and a back rest.
  • the middle section which is attached to the chassis equipped with floor rolls, maintains its position with all adjustment movements.
  • To the The lower leg and the backrest are pivotally articulated and connected via a coupling rod.
  • the coupling rod ensures that when the backrest is raised, the lower leg rest is simultaneously lowered. If the backrest is pivoted from the vertical position towards an inclined position, the lower legrest is pivoted upwards. An adjustment movement of the middle part or an adjustment of the backrest or the lower leg rest alone are not possible with the known transport chair.
  • the invention has for its object to design a patient bed of the type mentioned so that either the lower leg rest with the backrest synchronously in opposite directions of rotation or the lower leg rest and the backrest are independently adjustable.
  • the device for locking the linkage parts of the telescopic linkage and the coupling means for the actuating devices of the telescopic supports can be actuated synchronously via a Bowden cable, which can be brought into its switching positions via a handle.
  • the sick bed shown in FIGS. 1 to 4 has a backrest 1, a middle part 2 and a lower leg rest 3, which form the lying surface of the sick bed.
  • the backrest 1 is pivotably articulated in an articulated axis 4 and the lower leg rest 3 in an articulated axis 5 on the central part 2.
  • the backrest 1 is rotatably supported about an axis 6 and the lower leg rest 3 about an axis 7 in the frame of the hospital bed.
  • the hinge axes 4 and 5 are in the space between see the axes of rotation 6 and 7 and also move in the different positions of the backrest, middle section and lower leg rest in this room.
  • This arrangement of the hinge axes 4.5 between the backrest 1 and the middle part 2 or the lower leg rest 3 and the middle part 2 with respect to the fixed axes of rotation 6 and 7 makes it possible for the patient to support the adjustment movements of the lying surface parts with his body weight.
  • the adjustment device of the hospital bed has two telescopic supports 8, 9, which are articulated with their outer tubes 10, 11 at the rear end to brackets 12 which are fastened to the middle part 2 in the region of their flanges 13.
  • the extendable tube 14 of the telescopic support 8 is articulated on a bracket 15 which is fixed to the backrest 1 with its fastening flange 16.
  • the extendable tube 17 of the telescopic support 9 is articulated on a bracket 18 which is fixed to the lower leg rest 3 with its fastening flange 19.
  • energy stores e.g. uncontrolled or controlled gas springs can be provided, by means of which the weights of the lying surface parts to be adjusted are compensated.
  • the actuating device for the telescopic supports 8, 9 has handles 20 which are connected to one another via a shaft 21 which is rotatably mounted in the frame of the hospital bed. From Fig. 2 it follows that the handles 20 can be actuated from both sides of the bed.
  • a lever 22 is attached to the shaft 21, which carries a pin 23 which engages in an elongated hole 24 of a rod 25 which leads to the actuating lever 26 of a blocking device 27 of the telescopic support 8.
  • the blocking device 27 has one Locking bolt 28, which is guided in a housing 29 which is attached to the outer tube 10 of the telescopic support 8.
  • the bolt is fixed via a cross pin 30 to the upper part 31 of the housing, which has an inclined surface 32 which extends at the same angle as an inclined surface 33 of the housing.
  • the locking bolt 28 has a collar 34 on which a cylindrical helical spring 35 is supported.
  • the locking end 36 of the locking bolt engages in a locking recess 37 of the extendable tube 14.
  • the extendable tube 14 is provided with a series of locking recesses 37.
  • Fig. 4 it follows that the pin 23 is coupled to a rod 38 which runs parallel to the rod 25 and leads to an actuating lever 39 of a blocking device 40, which is constructed in the same sense as the blocking device 27.
  • a blocking device 40 which is constructed in the same sense as the blocking device 27.
  • At the end of the rod 38 there is an elongated hole 41 through which an idle stroke is achieved in relation to the actuating lever 39, provided the shaft 21 and the lever 22 are rotated counterclockwise in FIG. 3. In this case, the blocking device 27 is brought into its unlocked position.
  • the blocking device 40 is brought into the unlocked position via the rod 38, while the pin 23 is in the slot 24 makes an idle stroke so that the blocking device 27 is not actuated. In this case, the blocking device 40 releases the extendable tube 17 of the telescopic support 9, so that the lower leg rest 3 can be adjusted.
  • a telescopic linkage 42 is arranged between the actuating levers 26 and 39 of the blocking devices 27 and 40.
  • a spring 44 is provided which is supported at one end on the extendable rod 45.
  • the extendable rod 45 is articulated on the actuating lever 26 of the blocking device 27.
  • the extendable rod 45 can be fixed relative to the outer tube via a locking device 46. If the telescopic linkage 42 is locked and forms a coupling rod between the actuating levers 26 and 39, the blocking devices 27 and 40 are brought into an unlocked position when the handle 20 is actuated, so that the backrest and the lower part leg rest can be adjusted at the same time.
  • a telescopic linkage 47 is arranged between the backrest 1 and the lower leg rest 3.
  • the outer tube 48 is designed as a flat rectangular tube and is articulated on the bracket 18 via a bracket 49.
  • a locking device 50 is fastened to the outer tube 48 and is constructed in the same way as the blocking devices. It has a housing 51 with an inclined surface 52 with which the inclined surface of an upper part 53 interacts.
  • a locking bolt is fastened to the upper part, which is slidably mounted in the housing 51 and is loaded with a spring. The locking bolt engages in a locking recess 54 of an extendable part 55.
  • the extendable part 55 is articulated on a bracket 15 of the backrest 1.
  • a handle 56 is fastened to the upper part 53 and must be brought into the position shown in solid lines in FIG. 3 in order to initiate the locking of the parts 48 and 55 of the telescopic linkage.
  • the locking device 50 for the telescopic linkage only snaps between the backrest and the lower leg rest when the backrest has assumed an inclined position of approximately 30 °. Only from this point in time is the lower leg rest 3 lowered when the backrest 1 is raised further.
  • a Bowden cable 57 is provided, via which g nges 47 at the time of locking of the telescopic linkage Locking of the telescopic linkage 42 is made so that only the handle 56 needs to be actuated when switching to simultaneous actuation of the backrest 1 and the lower leg rest 3.
  • the handle 56 is shown in FIG. 3 in dash-dotted lines in the position in which the locking devices of the telescopic linkage are released.
  • the handle 56 is equipped with a stop arm 58 which cooperates with the front edge of the tab 12.
  • the stop arm 58 works together with the bracket 12, so that the handle 56 is pivoted into the unlocked position.
  • the telescopic linkage 60 provided between the backrest 1 and the lower leg rest 3 assumes an acute angle in the horizontal position of the lying surface parts with respect to the lying surface.
  • an arcuate arm 61 is attached, which projects with its free end into the area below the middle part 2 and to which the extendable part 62 of the telescopic linkage 60 is articulated.
  • a bracket 63 is attached to the lower leg rest 3, to which the outer tube 64 of the telescopic linkage is articulated.
  • the telescopic linkage is assigned a locking device 65, which is coupled via a Bowden cable 57 to the locking device 46 of the telescopic linkage 42 of the actuating device for the telescopic supports 8 and 9.
  • the locking devices 65 and 46 can already be switched on in the horizontal position of the lying surface parts. During the entire adjustment movements of the backrest 1 and the lower leg rest 2, the locking devices 27 and 40 assigned to the telescopic supports 8, 9 are in the released position.
  • the arrangement of the telescopic linkage 60 shown in FIGS. 8 to 10 ensures that when the backrest 1 is pivoted out of the horizontal position, the lower leg rest 3 initially does not move visibly. Only after a certain adjustment angle of the backrest 1 is the lower leg rest 3 pivoted more intensely.
  • the lying surface parts 1, 2, 3 assume a sitting position for the patient.
  • This illustration also shows that the middle part 2 has been moved into an inclined position.
