Definitions

  • the invention relates to a bed for immobile patients, in particular to its drive.
  • Beds for immobile patients are known in numerous designs, but they all have a large construction effort and are accordingly expensive. Apart from this, most of the designs only relocate the patient from one position to another, which is helpful, but it is impossible in practice to change the position of the patient as often as it should be.
  • swivel beds have also become known which carry out a slow back and forth movement of the bed frame about its longitudinal axis and thus ensure a permanent slow change in position of the patient, if desired.
  • the bed frame is pivotally mounted on the bed frame posts over the head and foot sections.
  • the drive is via a V-belt with all the disadvantages that occur with this type of drive, in particular the risk of more or less slipping through the side position of the frame, which can expose the patient to extremely unpleasant bumps.
  • the pivotable bed frame is mounted in a very protruding frame and the bed frame is also very solid within a U-shaped part.
  • the invention has set itself the task of creating a drive for swivel beds, in particular of the latter type, using bed frames designed with circular segments, which enables a smooth, shock-free and safe pivoting of the patient and also ensures a compact and largely maintenance-free design.
  • the pivoting of one or more disks and segments of the bed frame takes place via a deformable member connected and guided with a disk or segment, which runs and is driven via a group of wheels and / or rollers.
  • the segment can also be designed as a circular ring segment.
  • the individual disks or segments show such a profile that rails running in the form of a U-shaped depression are provided on both sides in the arc of the segment and a groove extending over the entire arc on the circumference.
  • this channel there is a chain, preferably a roller chain, a cable or a toothed belt, which is attached to the segment ends and runs over three adjacent wheels and / or rollers, one of which is driven, preferably arranged next to one another under the segment .
  • bolts are arranged on a stand in a corresponding arc, which engage in the U-shaped rail of the segment via roller or ball bearings. These stands with the bolts can be arranged on both sides of a segment.
  • a cable pull with three or more rollers can also take place, the drive roller being wrapped several times by the cable pull.
  • a toothed belt can also be used, which is equipped with teeth either on one side or on both sides. If the toothed belt has teeth on only one side, only the drive wheel is a toothed belt wheel, while rollers are provided next to the toothed belt wheel for deflection. Only toothed belt wheels are used for equipping on both sides.
  • the drive of the middle sprocket and thus the segments is mediated by a motor which rests on the foot of the bed and which allows the pendulum speed to be regulated and which can be controlled both by the staff and by the patient.
  • the inclination achieved with the bed according to the invention can be up to 82 ° with a segmental arc of 210 °.
  • a bed frame has several segments, preferably only one of the segments is driven and the other segments are connected to it via spacer bars.
  • two or more segments can also be driven.
  • the task is to equip swivel or pendulum beds so that the contact surface of the patient can be aligned according to the longitudinal axis of the body defined by the sense of balance.
  • the invention is based on a swivel or pendulum bed of the aforementioned type, namely the frame with one or more swivel bearings ten support elements, in particular circular segments, is equipped for the bed frame or the support surface.
  • the swivel bed for immobile patients is equipped with a height-adjustable support device for the bed frame or the support surface, which is carried by the bed frame. The height-adjustable support device rests on the support elements, in particular the circular segments.
  • the circular segments are preferably designed as ring segments and carry one or more secant-shaped cross members on which the height-adjustable support device rests.
  • the support device consists of a base fastened to the frame and a table which engages in a height-adjustable manner and which supports the bed frame or the support surface for the patient.
  • the pedestal consists of a plate attached to the crossbeams, which is equipped with spindle nuts, into which spindles engage, the upper ends of which are supported by ball bearings in blocks, which in turn support the table top for the bed frame or the support surface of the patient.
  • the spindles are preferably equipped with sprockets and operatively connected via a chain, one of the spindles being driven by a handwheel or otherwise. Instead of the sprockets, gears or rollers can also be used, and the chain can be replaced by gears or ropes.
  • Fig. 1 shows a side view of the bed frame on which the bed frame or bed plate is placed.
  • the bed frame 1 consists of two synchronously pivotable circular segments 2 and 3.
  • cam disks can also be used.
  • the segments 2 and 3 are connected via horizontal spacer bars 4 running in the longitudinal direction.
  • the circular segments are supported and guided by and by means of the stand 5, as will be described in detail later. It is driven by the motor 6, the shaft 7 of which drives the central sprocket of the segment 3, as will be explained later.
  • the stand 5 and the motor 6 rest on a foot part 8, which is designed to be rollable in an expedient manner.
  • Fig. 2 shows the circular segment 3 in front view.
  • the circular segment 3 is designed as a circular ring segment and for Engagement of the guide and drive means profiled.
  • the segment 3 is driven by a chain 17, e.g. a roller chain, as can be clearly seen from FIG. 2.
  • the chain 17 runs in the groove 18 located along the entire circumference of the segment and is secured at the ends of the segment by known measures, e.g. Pins, secured.
  • On the stand 5, three sprockets 20, 21, 22 are rotatably supported, of which the middle 21 is driven via the shaft 7 of the motor 6.
  • the drive wheel 21 is thus flanked by two deflection wheels 20, 22.
  • the chain is guided over these wheels, as can be seen from Fig. 2a.
  • the arrangement of three wheels means that a relatively long part of the chain is in engagement with the teeth of the wheels, which ensures a permanent tension of the chain and also greatly reduces wear. In this way, a smooth pivoting movement of the segments is ensured.
  • the deflection of the swiveling movement and the speed of the movement is electronically controlled and can be set by the staff and the patient if he is able to do so
  • the parts provided with the reference numerals 20, 21, 22 are rollers, the roller 21 being driven and wrapped several times by the cable.
  • a toothed belt is used, depending on the two-sided or one-sided toothing in the parts 20, 21, 22, gears or a centrally arranged toothed wheel 21 with flanking deflecting rollers 20 and 22 can be seen.
  • a cable pull or a toothed belt can also be assigned to reference number 17.
  • the chain drive is preferred because of its extensive temperature independence are given.
  • bolts 23 are attached in a corresponding arc shape to the stand 5 and engage via rails 24 in rails 25 of the segments 2, 3.
  • the rails 25 correspond to the arc run of the segment and are formed by U-shaped depressions on both sides of the segment.
  • the ball bearings are adapted to the rail width and compensate for the unevenness that could lead to impacts.
  • stands 5 with bolts engaging in the rails 25 can be arranged on both sides of the segments, as in the case of the directly driven segment 3 or only on one side as in segment 2.
  • the pivoting is carried out by segment 3 via the spacer rods 4 already mentioned transferred to segment 2.
  • Fig. 3 shows a plan view of the bed frame 1, the horizontal spacer bars 4 between the segments 2 and 3 are clearly visible and also in connection with Figures 3a and 3b, the profiling of the segments 2 and 3.
  • the segment 3 shows on both Side rails 25 and circumferentially the groove 18 for the chain 17, while the segment 2 has a rail 25 only on one side and the groove is completely eliminated.
  • the segments most appropriately have or span an arc of 210 °, but this can also be drawn larger. It is also possible to use a circular ring.
  • the drive according to the invention does not presuppose that the cams are circular segments, but can be used with everyone Curvature of the curve can be used.
  • Fig. 2 also shows the support device 11.
  • the circular segment 3 has a secant cross member 10 extending in the ring segment, which at 14 and 15 with the flange 16 of the ring segment 3, e.g. is connected by screw.
  • the segment 2 also has such a cross member.
  • These cross members 10 support the support device 11 for the bed frame, the bed board or another support surface for the mattress.
  • This support device 11 consists of a base 12 fastened to the cross beams 10, in which a table engages in a height-adjustable manner, so that the patient can be positioned depending on his personal dimensions so that the pendulum axis coincides with the longitudinal axis of the body defined by the sense of balance. In this way it is achieved that the patient does not experience dizziness when swiveling the pendulum bed.
  • Fig. 4 shows a possible embodiment of a support device 11 in detail.
  • the pedestal shows a plate 26 which is attached to the cross members 11 of the segments 2 and 3 via brackets 27 fastened thereon, for example by screwing.
  • the cross members 10 reach through corresponding openings in the brackets 27.
  • the plate 26 carries spindle nuts 28.
  • spindles 30, 30a provided with screw threads engage in these spindle nuts.
  • One of the spindles 30a carries a handwheel 31 at the lower end for the purpose of driving, which can be locked in any set position.
  • the chain wheels are connected to one another via a chain 33.
  • the upper ends of the spindles 30, 30a engage via ball bearings 34 in blocks 35 which are fastened to the plate 37 and 13 by screws 36 and carry them.
  • the spindle 30 When the handwheel is turned, the spindle 30 is retracted or extended on one of its nuts and thus the spindles 30 in the same way, since they are driven synchronously with the spindle 30 via the chain 33 and the chain wheels 32.
  • the table 13 which carries the bed frame or the surface for supporting the mattress, can be raised or lowered and can thus be easily adapted to the circumstances.
  • the drive spindle can also be operated in some other way, and transmission can take place not only via sprockets, but also via gear wheels and rollers using toothed belts and ropes.
  • the support device according to the invention is not limited to the bed frame described, but can generally be used with swivel or pendulum beds if only supports for the support device which pivot with the bed are present.
