Definitions

  • the invention relates to a hospital bed with a motorized height and / or inclination adjustable by means of a lever linkage and also lockable in the respective height and / or inclination positions, and a base frame mounted on rollers.
  • a patient bed is known according to the preamble of claim 1. It is also known from DE 92 10 439 to raise or lower such a patient bed by means of a so-called scissor lifting device. However, this does not suggest that by dividing one scissor arm into two complementary swivel levers, the bed can be adjusted both in height and in inclination.
  • the invention has for its object to design a sickbed of the type required in claim 1 such that it allows a deep lowering of the lying surface frame with the required ground clearance, so that even elderly and frail patients can easily get into the bed and leave it again.
  • the lying surface frame is adjusted in height and / or inclination by a scissor-type lever linkage and also locked in the respective height and / or inclination position. Due to the special design and arrangement of the lever linkage, the lying surface frame can be lowered almost to the base frame and thus to the undercarriage chassis, so that the distance between the floor and the upper edge of the lying surface frame is relatively small. As a result, old and frail patients can easily get into the bed and control the desired height and / or inclination position even by switching on the motor drive, so that they can also be left without outside help.
  • a particular advantage is the relatively simple design and arrangement of the lever linkage causing the drive, which in extreme cases can consist of two scissors-like levers, one lever being made of one piece and continuous material and having ends at its ends on pivot axes that run horizontally and parallel to one another on the one hand with the Lying surface frame and on the other hand can be connected to the undercarriage or undercarriage via a longitudinally displaceable backdrop, while the other lever arm consists of two lever parts which are pivotable relative to one another about a horizontal axis.
  • the bed frame can also be adjusted in height parallel to the base.
  • the scissor-like lever linkage enables a relatively large stroke of the lying surface frame relative to the base frame.
  • the lever which is made of one piece in terms of material, and the lever consisting of two lever parts are each arranged in pairs.
  • the pairs of levers can be arranged in the area of the two long sides of the bed. This results in a particularly stable construction.
  • Claim 3 describes an advantageous embodiment of the invention.
  • Claim 5 describes a further advantageous embodiment of the invention.
  • Reference number 1 designates a lying surface frame on which the bedding (not shown) is arranged.
  • the backrest, heart and foot section have not been illustrated in detail; they can have the usual training and arrangement.
  • the reference numeral 2 denotes a base frame which can be moved on rollers 60 on the floor, which is not designated in any more detail.
  • the rollers 60 are arranged in pairs in the corner points of the base frame 2, so that a total of four such rollers 60 are provided, of which at least two can be designed to be braked in a conventional manner (not shown).
  • Base frame 2 and lying surface frame 1 consist of profile tubes.
  • lifting levers 3, 4 designate lifting levers which are arranged parallel to one another and are pivotably mounted in the vertical direction and are arranged in the region of a longitudinal side of the hospital bed.
  • Each of the lifting levers 3, 4 is arranged so as to be pivotable about a horizontally running pivot axis 5 which is mounted immovably on the lying surface frame 1.
  • the pivot axis 5 can also be divided.
  • the lifting levers 3, 4 carry out synchronous movements in the same direction.
  • the lifting levers 3 and 4 are also pivotably mounted in the vertical plane about a pivot axis 6 which runs horizontally and parallel to the pivot axis 5.
  • the pivot axis 6 is mounted on a sliding block.
  • the sliding block 7 has been provided with a reference number in the drawing.
  • the other sliding block is designed and arranged as described below in connection with the sliding block 7.
  • the sliding block 7 is arranged in a longitudinally displaceable manner in the longitudinal axis direction of the respective horizontal longitudinal spar 8 of the base frame 2 in a sliding block guide 9 which extends over a considerable length section of each of the longitudinal spars 8 of the base frame 2.
  • the link guides 9 of each longitudinal spar 8 are the same size, the same length and limited by the same planes, so that the two lifting levers 3 and 4 are only able to perform the same movements with their axes 6 and thus with their link blocks 7.
  • a pair of swivel levers is arranged in the area of each long side of the bed, each consisting of two swivel levers 10, 11 and 12, 13, respectively. All pairs of pivot levers 10 to 13 are arranged on a common horizontally arranged and thus parallel to the pivot axes 5 and 7 pivot axis 14 pivotally. As can be seen from FIGS. 5 and 10, the pivot axis 14 can also consist of two parts which are mounted coaxially to one another.
  • the pivot levers 10 and 12 are each pivotally mounted on their lower end section by coaxial and horizontal pivot axes 15 and 16 on the base frame 2 in the vertical plane.
  • the pivot levers 11 and 13 are coupled to each pivotable axis 18, 19 with a sliding block 20, 21 in a vertical plane.
  • the pivot axes 18 and 19 run parallel to the pivot axes 15 and 16, so they are arranged horizontally.
  • the pivot axes 18 and 19 are coaxial with each other.
  • the sliding blocks 20 and 21 are each arranged in the same size in the longitudinal axis direction of the relevant profile tube of the lying surface frame 1 sliding guide 22 and 23 in the same direction and equally displaceable by a limited amount.
  • a connecting tube 26 is fixed, for. B. connected by welding, so that the pivot levers 11 and 13 are integrally movable over the connecting tube 26.
  • the connecting tube 26 on both sides of the longitudinal center axis 27 (FIGS. 4 and 10) of the hospital bed, a pair of tabs 24 and 25 projecting downwards in one piece, in particular also by welding, and thus firmly connected.
  • the pairs of tabs 24 and 25 are arranged coaxially to one another, thus aligned through-bores, through which pivot axes 28 and 29 (FIGS. 5 and 10) engage, to which a piston rod 30 or 31 of gas springs acts via a fork or the like.
  • the cylinders 32 and 33 are each mounted on pivot axes 34 and 35 parallel to the pivot axes 28 and 29 on pairs of tabs 36 and 37 (FIGS. 5 and 10) so that they can pivot in the vertical plane.
  • the pairs of tabs 36 and 37 are attached in one piece, in particular by welding, to a connecting tube 38 which is arranged coaxially on the connecting tube 38 and is fixedly connected to the pivot levers 10 and 12, in particular by welding.
  • the gas springs are arranged so that they are able to secure the bed frame 1, the lifting linkage and a person thereon against falling.
  • the relevant gas pressure springs can be designed such that the piston rods 30 and 31 can only be moved into the cylinders 32 and 33 at a predetermined speed.
  • the gas pressure springs can be provided with a corresponding throttle through which the medium can flow into the other cylinder space in order to enable the telescopic parts of the gas pressure spring to be pushed together. Hydraulic or electric linear motors or spindle drives can also be used instead of gas pressure springs.
  • suitable throttle bores can also be provided, through which the pressure medium in question can flow in order to prevent the lying surface frame 1 from falling down.
  • Reference numeral 40 denotes a drive motor, which can be designed as a linear motor.
  • the drive motor 40 can e.g. B. work hydraulically, electrohydraulically or mechanically.
  • the drive motor 40 has a cylinder 41 and a piston rod 42.
  • the cylinder 41 is mounted on the base frame 2 so that it can pivot about a horizontal pivot axis 43 by a limited amount in the vertical plane.
  • the free end of the piston rod 42 also engages around a horizontal pivot axis 44 which runs parallel to the pivot axis 43 and is mounted between a pair of tabs 45 which is connected in one piece to a cross tube 46 designed as a profile tube, in particular by welding.
  • the cross tube 46 is in turn coupled in one piece to the lower pivot levers 10 and 12 by welding or the like.
  • the pivot axis 44 is arranged at a distance A from the pivot axis 14.
  • the telescopic parts of the gas pressure springs are extended by about half before they are installed.
  • the characteristics of the gas pressure springs are so determined that they ideally compensate for the weight of the lying surface frame 1 and the bedding lying thereon (they can hold) or gradually push this weight upwards. In any case, they are designed and arranged in such a way that they prevent the patient's bed frame 1 from quickly lowering or even falling down.
  • the mode of operation of the embodiment shown in FIGS. 1 to 5 is as follows: Assume the bed is in the upper position of the lying surface frame 1 shown in FIG. 1, in which it is in a horizontal arrangement and the lying surface frame 1 is to be lowered on the foot side .
  • the blocking of the gas pressure springs is unlocked via a hand lever, not shown, so that the piston rods 30, 31 are gradually pressed into the cylinders 32 and 33 of the gas pressure springs by the weight of the patient and / or by pressure on the foot-side end of the lying surface frame 1 until the desired low position of the foot end is achieved.
  • the hand lever is released so that the gas pressure springs are blocked again and the predetermined inclination of the lying surface frame 1 is blocked thereby.
  • the lying surface frame 1 according to FIG. 3 is to be lowered on the head side from the position according to FIG. 1, the blockages of the gas pressure springs are also lifted by a hand lever, not shown, so that the patient's weight and / or by slightly lifting the foot-side end of the lying surface frame 1, the piston rods 30, 31 are gradually pulled out into the cylinders 32, 33, again until the desired inclination position according to FIG. 3 is achieved.
  • the lever is then released again and the gas pressure springs block a further lowering.
  • the sliding blocks 20, 21 shift in the sliding guides 22, 23, the sliding blocks 7 do not shift.
  • the drive of the linear motor 40 is switched on, which drives the piston rod 42 into the cylinder 40 (FIG. 4) until the desired low position of the lying surface frame 1 in relation to the base frame 2 is achieved.
  • the sliding blocks 20, 21 and the sliding blocks 7 move in the respective sliding guides 22, 23 and 9 respectively.
  • the blocking of the gas pressure spring is not affected by this, that is to say the angular position of the lying surface frame 1 with respect to the horizontal plane remains unchanged when the lying surface frame 1 is lowered .
  • simultaneous actuation of the swivel devices is also possible.
  • all intermediate positions, inclination head or foot side and / or height positions of the lying surface frame 1 with respect to the base frame 2 are possible. All of these positions of the lying surface frame 1 can be locked separately via the gas pressure springs and the motor drive.
  • the sliding blocks 20, 21 move in the sliding guides 22, 23 and the sliding blocks 7 in the sliding guide 9 (FIG. 4).
  • the motor drive 40 is controlled in its opposite position, in such a way that the piston rod 42 extends and presses the pivot levers 10, 12 upward via the pairs of plates 45 and the cross tube 46, which also results in a corresponding rotary movement of the gas pressure springs about the pivot axis 15, 16 results.
  • Each of the sliding blocks 50 is guided in a sliding block 51 in the longitudinal direction of the relevant longitudinal spar 8 of the base frame 2 so as to be longitudinally displaceable. Consequently, the sliding blocks 50 and the other sliding block are arranged synchronously and parallel to one another, and are mounted on the base frame 2 so as to be longitudinally displaceable.
  • the cross tube 49 is rotatably coupled to each of the sliding blocks 50 about a horizontal pivot axis 39.
  • Support tubes are arranged on the cross tube 49 at a distance and parallel to one another and at the same angular positions to the cross tube 49, of which only the support tube 52 has been provided with a reference number in the drawing.
  • the other support tube is designed and arranged in the same way as described below.
  • a support rod 53 is arranged in a longitudinally displaceable manner in each support tube 52.
  • Each support rod 53 is pivotally connected at its end about a horizontal pivot axis 54 on the longitudinal center axis of the lower pivot lever 10 or 12 in the vertical plane.
  • the pivot axis 54 can be assigned to the two support rods 53 together and thus extend in one piece between the two lower pivot levers 10 and 12.
  • the pivot axis 54 is also pivotally coupled to the lower pivot levers 10 and 12.
  • the support rods 53 are telescopically loosely arranged in the respective support tube 52. About the length of the support rods 53 will be made below.
  • a curve piece 55 of the same size is fastened in the same height and angle range, which is delimited on the rear side 56 by a rectilinear wall, while it is delimited on its front side by a concavely curved wall 57.
  • the curve pieces 55 are coupled in one piece by a horizontally extending rod 58.
  • the curve pieces 55 are integrally connected to the respective support tube 52 by welding.
  • the bolt can also be a rotatable or non-rotatable tube.
  • the bolt 59 itself can also consist of a friction-reducing material, in particular a plastic.
  • the distance of the bolt 59 to the pivot point of the pivot axis 54 or the position of the bolt 59 on the pivot levers 10 and 12 and the length of the support rods 53 are selected so that on the one hand the bolt 59 limits the lowering of the lying surface frame 1 downwards, on the other hand at Actuation of the drive 40 an immediate lifting of the bed frame 1 is initiated.
  • the support rods 53 When lowering, the support rods 53 are initially supported on the lower cross tube 49 until a position is reached in which the bolt 59 gradually rests on the concave wall 57 of the curve pieces 55 without force or pressure jump, after which the support rods 53 gradually move out their support tubes 52 are pulled out (Fig. 9), so no longer rest on the cross tube 49. In this position, the power transmission takes place exclusively from the bolts 59 or the like via the concave walls 57 of the curve pieces 55, the support tubes 52, the cross tube 49, the pair of links 47 and the piston rod 42 for the motor drive 40.
