Definitions

  • the invention relates to a bed provided with a base frame and a frame which can be moved above it and which can be adjusted in height with the aid of a linkage with respect to the base frame.
  • the aim is to make such a bed more universal so that it can be easily used for the various positions required in hospitals and similar institutions, while the bed should take up as little space as possible when not in use.
  • the bed according to the invention is characterized in that the base and the frame are connected to one another by two rods, the first of which is rotatably connected to the base at one end and slidably connected to the frame at the other end, while the other , second rod, with one end rotatably connected to the frame and with its other end slidably connected to the base.
  • the bed can be set up either with the front end up and with the rear end down or vice versa.
  • the second rod can be controlled by a short, third rod, one end of which is rotatably connected to the base, while the other end is rotatably connected to the second rod.
  • the third rod can be fixedly connected to an axis rotatably connected to the base frame, on the latter of which a further rod is fixedly attached, the other end of which can be actuated by a piston-cylinder system or by a similar drive. In this way, very simple operation is possible.
  • a connecting rod the other end of which is rotatably connected to the first rod, can be connected to the coupling point of the piston-cylinder system with the further rod.
  • the connecting rod can be parallel to the base and can also be adjustable in length if necessary. This provides a large number of setting options.
  • the bed according to the invention can further be provided with an adjustable lying surface set up above the frame, which consists of several parts which can be adjusted with respect to one another.
  • the lying surface can essentially consist of five parts which can be adjusted with respect to one another, one of which the frame is formed and only a part is directly rotatably connected to the frame, that is to say that the lying surface is divided into at least five parts which can be adjusted with respect to one another and can optionally be adjusted with respect to one another. In this way, any position desired for a patient or for the treatment of a patient can be achieved.
  • the back part can be supported by a tilting part that is rotatably connected to the frame and to which tilting part an arm connects, which is controlled by a push-pull rod.
  • Said pull-push rod can be received between the ends of two levers, one end of which is rotatably connected to the frame, while the other end is rotatably connected to the back part, and the drive rod for the tilting part engages on one of the latter levers .
  • the other end of the drive rod or the end of the cylinder cooperating with said drive rod can engage on one end of a rod whose other end is rotatably connected to the frame and on said end of the rod (the other end of which is rotatable with is connected to the frame) also engages one end of a piston-cylinder system or a similar device, the other end of which controls a further adjustable part of the lying surface.
  • a further improvement in relation to known beds can be achieved in that the bed is provided with a side wall grille which can be set up or locked in several positions. In this way it is achieved that the grille can be brought into a somewhat elevated position, so that patients who can easily fall out of bed at night in the absence of such an elevation are protected, while at the higher position of the grille also patients who are tend to be prevented from "climbing" out of bed.
  • the above-mentioned height adjustment can be carried out with the aid of a single locking element acting on the upper rod.
  • the locking element can consist of a locking handle which is provided with a pawl which can cooperate with openings made in the two tubular parts for locking the rod parts to one another in a certain position.
  • the intermediate, essentially horizontal rod can be provided with slot-shaped recesses for cooperation with pins attached to the connecting rods.
  • the actuation mechanisms which are moved downwards in this way can move at least two swivel wheels set up next to one another by means of a foot-actuated bracket be connected. This will keep the entire space above the frame parts free for folding the whole bed.
  • a bed which is generally indicated by 1
  • an underframe generally designated 2
  • a frame 3 movably arranged above it.
  • the two parts are connected by two rods 4 and 5, respectively.
  • the first rod 4 is rotatably connected to the base frame 2 at the location of an axis 6 and slidably connected to the frame 3 by means of an axis 7.
  • the second rod 5 is in turn rotatably connected to the frame 3 by means of an axis 8 and slidably connected to the base frame 2 by means of an axis 9.
  • a third rod 11 is attached to the rod 5 in the middle thereof via an axis 10, the other end of which is firmly connected to an axis 12 fastened to the base frame 2.
  • the "free" end of the rod 13 is provided with an axis 14, on which both the rod 15 of a piston-cylinder system 16 acts, which is rotatably connected to the base frame 2, while a coupling rod 17 also adjoins it, which telescopes with a rod 18 can cooperate, the free end of which is connected to an axle 19 received between ears 20 fastened to the rod 4.
  • a simple, secure adjustment of the frame 3 with respect to the base frame 2 is possible.
  • a number (generally four) swivel wheels 21 are mounted under the base. These swivel wheels can be of known construction and can be designed such that the swivel wheels, both in terms of their position and their possibility of rotation, can either be rotated freely in a rotative sense but in a fixed position, or completely freely rotatable in both a rotative sense and rotatable in relation to the direction of movement.
  • piston cylinder system 15, 16 is rotatably attached to the ears 22 attached to the underside of the longitudinal members of the undercarriage, these elements can also be attached to the upper side of the longitudinal members of the undercarriage, whereby the space under the undercarriage is free.
  • the base frame can be set up in three different positions, it being apparent from FIG. 2 that the entire base frame including the frame can also be completely folded up, in such a way that the whole has a minimal space takes up.
  • a lying surface 23 is attached to the frame 3.
  • This lying surface essentially consists of five parts, namely a back part 24 with a head part 90 rotatably connected to it (the connection and the adjustment options of the head part 90 with respect to the back part 24 are not shown because they are well known).
  • a part 25 of the frame 3 adjoins the back part 24, a part 26 for the thigh region and a part 27 for the legs.
  • the parts of the bed surface can be moved as follows.
  • the back part 24 is supported by a tilting part 29 which is provided with an axis 30 which is rotatably attached to ears 31 on the frame 3.
  • the relevant end of the tilting part 29 is provided with a roller or a slider 32 which is rotatably connected thereto.
  • an axis 32 a is further attached, which is rotatably connected to a rod 33, the other end engages by means of an axis 34 on an arm 35 which is fixedly connected to the frame 3 by means of an axis 36.
  • One end of the arm 35 is rotatably connected to the lower end of the back part 24 by means of an axis 36.
  • An axis 37 is connected to the opposite end of the arm 35, to which one end of a pull-push rod 38 also connects.
  • the other end of the push-pull rod 38 is connected to an axis 39, to which on the one hand an arm 40 is connected, the other end of which is connected by means of an axis 41 to ears 42 fastened to the frame 3.
  • a pull-push rod or a piston-cylinder system 43 also acts, the other end of which is rotatably connected to an axis 44 which is fastened to levers 45, the other end of which is fixedly connected to an axis 46 which leads to the part 27 heard for the legs.
  • the tilting part 29 can be actuated by a schematically represented pull-push rod 38, but also on each can be operated in any other way, for example by a worm, worm gear transmission, a piston-cylinder system and the like.
  • This side rail consists essentially of four rods 48 rotatably connected with connecting pieces 47.
  • the other ends of the rods 48 are rotatably connected to connecting pieces 49, which are firmly connected to a rod 50, 51 consisting of two telescopic parts.
  • the side rail for restless patients is completed by an intermediate rod 52.
  • slots 53 are provided in the intermediate rod for the passage of connecting pins 54.
  • a tubular locking handle 55 is attached to the "free" end of the rod 51.
  • the details of this locking handle are shown exactly in Figures 7 and 8. 8, the locking handle is provided on the inside with a pawl 57 rotatably connected to an axis 56, which is under the load of a spring 58.
  • a locking part 59 is designed such that in the position shown in solid lines in FIG. 8 with openings 60 or 61 of the tube 50 or 51 can work together.
  • an unlocking at least a movement of the pawl 59 can be effected from the locking opening 60.
  • This allows the rod 51 to move freely with respect to the rod 50.
  • the locking handle 55 is now released to a certain extent, it will be moved back into the starting position under the influence of a spring 62 and, if the side rail is moved further up or down, will automatically cause a locking in a next position for the restless patient, in which the openings 60 and 61 aligned.
  • Such an opening 60 is clearly shown in FIG. 7.
  • a swivel wheel 21 (not shown) is attached to a horizontal longitudinal beam of the underframe 2.
  • a horizontal, hexagonal actuation axis 80 protruding beyond the base frame 2 can be brought into three positions, in which positions the wheel 21 can be freely rotated and swiveled in succession, or in a second position in which the wheel can be rotated but not swiveled, or in a third position, in which the wheel is not rotatable and not pivotable. Because this is well known in itself, it will not be described further here.
  • This transmission construction ends in an axis 81 rotatably mounted under the longitudinal beam of the undercarriage, which can be actuated by a bracket 82 which can extend transversely under the bed to a similar construction which is connected to a drive shaft 80 of an adjacent swivel wheel.
