Definitions

  • the invention relates to a portable lifting device for a bed frame for lifting and lowering the bed frame.
  • Lifting devices for the stated purpose in particular for use in hospitals, are known and represent heavy, mostly mobile devices that can be transported from one place of use to another within a hospital and also to different floors by means of a lift, but which are too heavy and extensive are in order to be able to use them in the private household for care needs.
  • Caring for a bedridden patient in the private household is a major physical effort for a nurse who is constantly practicing this care, which leads to back problems, because the low height of most beds means that the nurse always has to do her job with a stooped posture and her back strong is claimed. These difficulties very often represent the reason for the job.
  • the object underlying the present invention was therefore to provide a device which is handy and easy to transport, so that it can be carried by one person and can also be carried comfortably in the trunk of a car, so that a nurse for nursing care in the private household has such a device on hand in case of need, thereby making work easier.
  • the back of the carer is less stressed, in particular when lifting and moving a patient, which makes the care work easier.
  • a simple and inexpensive device will also be left in one place for the duration of a care case.
  • the device of the type mentioned at the outset is characterized in that a first and a second adjustable support frame each have a horizontal support for reaching under the bed frame frame and two handlebars pivotably hinged to one another at one end and has a foot on which the handlebars are articulated at the same distance from one another and form a joint parallelogram with the foot and the support, that in both support stands the piston rod of a hydraulic lifting cylinder supported on the foot for each of the two handlebars the height adjustment of the support bracket is articulated and that the two support brackets are connected to one another by means of achieving the synchronization of the lifting movement of the two support brackets and at least one lifting cylinder can be actuated by a pump.
  • the means for achieving the synchronism of the lifting movement of the two support frames consist of two identical lifting cylinders with the same lifting volume and the same stroke length and from a connecting line between these lifting cylinders.
  • One of these identical jacks is arranged on each of the two jacks, namely one of these jacks which is intended for the height adjustment of the jack and which is articulated with its piston rod on a handlebar of the jack, while the other of the two identical jacks additionally on the other jack to the articulated lifting cylinder, which is articulated with its piston rod on a handlebar of this support bracket and can be actuated for its height adjustment by a pump, in such a way that its piston rod, which is also connected to a handlebar, controls the handlebar movement by displacing the pressure medium from one lifting cylinder to the other in the opposite direction Transmits the piston rod of the lifting cylinder intended for the height adjustment.
  • one support frame has a lifting cylinder and the other support frame has two lifting cylinders, one of which serves as a control cylinder, the movement of the handlebar, which is moved by the existing second lifting cylinder, which can be actuated by a pump, hydraulically precisely onto the piston rod transmits a lifting cylinder on the other support frame.
  • the piston retracts in the lifting cylinder acting as the control cylinder, whereby the piston in the lifting cylinder on the other support frame is extended.
  • a lifting cylinder with an integrated pump can also be provided in each support frame, which can then be operated simultaneously.
  • an actuating rod connecting the actuating levers of the two pumps can then be expediently provided, which is thus located between the two support brackets parallel to the long side of the couch frame extends if the two trestles are preferably arranged transversely to this frame.
  • This embodiment in which the two pumps which can be actuated together and the actuating rod connecting their actuating levers to one another represent the means for achieving the synchronism of the lifting movement of the two support brackets, has the prerequisite for achieving this synchronism that the two lifting cylinders and pumps operate in exactly the same way the piston rods are extended by the same amount at the end and the bed frame remains in a horizontal position.
  • units consisting of a lifting cylinder and a pump which may not be expensive in the interest of cost-effective production of the device, there are differences at the end of a lifting movement between the stroke lengths achieved for one and the other lifting cylinder, for which purpose also air pockets, different friction, etc. are responsible so that the synchronism of the lifting movement is not guaranteed.
  • the lifting device has a support frame 1 according to FIG. 1 and a support frame 2 according to FIG. 2, which are parallel to each other at a distance of approximately 1.5 m under a couch frame 3 be set up in the transverse direction in order to raise or lower it from the raised position.
  • Each of the two trestles 1 and 2 has a carrier 4 which engages under the bed frame 3.
  • a first link 5 is articulated on the support 4 near the longitudinal center of the support by means of a pivot pin 6 and further a second link 7 is articulated near the support end by means of a pivot pin 8.
  • Each handlebar is designed as a two-armed angle lever.
  • the handlebar 5 with a long lever arm 5a and a short lever arm 5b is pivotally mounted at the intersection of the lever arm center lines by means of a pivot pin 9 on the foot 10.
  • the foot consists of a tube which is angled several times in the same plane and which has cross struts 10c extending perpendicularly to the plane of the drawing on the parts lying on the floor, so that the tube forming the foot can stand upright on the floor.
  • the handlebar 7 with a long lever arm 7a and a short lever arm 7b is pivotally mounted at the base 10 at the intersection of the lever arm center lines by means of a pivot pin 11.
  • the ends of the two short lever arms 5 b and 7 b are connected to one another by a coupling rod 12.
  • the two links 5 and 7 together with the support 4 and the foot 10 form a joint parallelogram in such a way that the support is moved parallel to itself when the handlebars are pivoted.
  • the pivot pins 6 and 8 describe an arc around the pivot pin 9 and 11, respectively, and the carrier 4 then assumes the position indicated by dash-dotted lines in FIGS. 1 and 2.
  • the construction of the support brackets 1 and 2 according to FIGS. 1 and 2 corresponds with respect to the support 4, the two handlebars 5 and 7 and the foot 10.
  • the two trestles 1 and 2 differ in the features described below.
  • the piston rod 15 of a hydraulic lifting cylinder 16 is articulated on the handlebar 5 by means of a pin 17.
  • the lower end of the lifting cylinder 16 is pivotally supported in the foot 10 by means of a pin 18.
  • a pump 19 is assembled, which has a pump actuating lever 20, 20a, which is to be pressed down against the action of a spring 21 in order to allow the piston rod of the lifting cylinder 16 to extend by pumping.
  • the handlebars 5 and 7 assume a horizontal position.
  • the support frame 1 also has a further lifting cylinder 30, the piston rod 31 of which is articulated on the coupling rod 12 by means of a pin 32.
  • the other end of the lifting cylinder 30 is pivotally supported on the foot 10 by means of a pin 33.
  • the piston rod 31 is initially fully extended and shown somewhat retracted in FIG. 1, which can be seen from the position of the piston indicated by dashed lines.
  • the coupling rod 12 also makes a corresponding movement to the right, so that the piston rod 31 of the lifting cylinder 30 retracts further and the pressure medium, preferably oil, present in the lifting cylinder 30 is displaced .
  • the lifting cylinder 30 of the support frame 1 is connected via a line 34 to an identically designed lifting cylinder 35 which is arranged on the support frame 2 according to FIG. 2.
  • the two lifting cylinders 30 and 35 have the same stroke volume and the same stroke length. 2
  • the piston rod 36 is in the retracted position at the beginning of a stroke adjustment.
  • the piston rod 36 is articulated on the coupling rod 12 by means of a pin 37.
  • the rear end of the lifting cylinder 35 is pivotally supported on the foot 10 by means of a pin 38.
  • Both identical lifting cylinders 30 and 35 are arranged essentially horizontally.
  • the pressure room of the Lift cylinder 35 in front of the piston and the connecting line 34 to the lift cylinder 30 and its pressure chamber are filled with the pressure medium without air.
  • the lifting cylinder 16 of the support frame 1 and the lifting cylinder 35 of the support frame 2 do not have to have the same stroke length. It is only important that the second lifting cylinder 30 of the support frame 1, which has the function of a control cylinder, is of the same design as the lifting cylinder 35 of the support frame 2 and that the same movement conditions are present in these two lifting cylinders.
  • the height of the support frame is also determined by the overall height of the lifting cylinder 16.
  • the support 4 has a U-shaped cross section, the two legs of this support pointing downward.
  • the links 5 and 7 are articulated on the inside of the legs of the cross-sectionally U-shaped support, these links also having a U-shaped cross-section and having a smaller width than the inside width of the support.
  • the two links can be in the lowest position of the carrier 4 within this carrier, wherein they extend parallel to the carrier.
  • the pins 6, 8, 9, 11 and 17 are then on a horizontal line.
  • the carrier 4 have upstanding brackets 25 at the ends, the spacing of which can be adjusted by screws, not shown.
