Definitions

  • the present invention relates to a lifting device for lifting a load, comprising a rigid carrier arm to be placed over the load, means for receiving the load, the carrier arm supporting said means for receiving the load, and transfer means connected to said carrier arm for parallel movement thereof in its lateral direction.
  • the lifting device is intended for lifting and/or moving a patient confined to bed between two places.
  • Such lifting devices are previously known for facilitating the work of the medical staff in hospitals and similar institutions for lifting and moving patients having reduced faculty of motion or being confined to their beds for other reasons.
  • Prior art lifting devices are often bulky and difficult to handle and require for handling often more than one person.
  • prior art lifting devices generally are mounted on the floor or a wall and so valuable space is lost in the room where the lifting device is accomodated.
  • the Swedish laid-open specification 7508892-2 discloses a patient lifter including a carrier bar supported by a lever which is pivotably supported by a horizontal shaft.
  • the carrier bar is movable in its lateral direction by rotation of said shaft.
  • This patient lifter can be handled by one operator and allows movement of a patient between two support surfaces, e.g. a stretcher and a bed, without intermediate movement of said support surfaces.
  • this patient lifter occupies a relatively large floor area.
  • the object of the present invention is to provide a new lifting device which obviates the above-mentioned drawbacks of prior art lifting devices and is particularly suited for operation in narrow spaces.
  • said transfer means includes two similar transfer assemblies each having a rigid link member pivotably connected to a respective and of the carrier arm, and a lever pivotably connected at one end to the associated link member and rigidly attached at its other end to a respective rotatable pivot shaft, and driving means connected with said pivot shafts, which driving means when actuated rotate the shafts in opposite senses, thereby lifting and moving the carrier arm laterally, the shafts of said transfer means being laterally spaced in one and the same vertical plane, and extending vertically or at an inclination to the vertical.
  • the lifting device according to the invention is directed to an application as a patient lifter.
  • the lifting device provided with a suitably structured load receiving means can be used for lifting any type of load.
  • the lifting device has a rigid carrier arm 1 with a longitudinal extension suitable for the particular application of the lifting device.
  • the carrier bar 1 includes a pipe or two parallel side members which are rigidly connected by means of cross members (Fig. 3).
  • Figs. 1, 4A and 4B most of the components of the lifting device are illustrated in a simplified manner by means of streight lines, crossing lines showing the presence of articulations for allowing mutual movement. However, it is emphasized that the components illustrated as straight lines in practice also have a lateral extension.
  • a load receiving means 2 for receiving and supporting a patient is connected to the carrier arm 1 and supported thereby.
  • Said receiving means is made releasable from the lifting device and can also include the carrier arm.
  • said load receiving means 2 is shown as consisting of several rigid yokes 3 connected to the carrier bar 1, lifting bands 4 being releasably attached to the legs of said yokes.
  • said load receiving means 2 can be embodied in various other ways, another suitable embodiment for receiving patients being shown in Fig. 3.
  • Rigid, preferably straight link members 5a and 5b are pivotably connected to both the ends of the carrier arm 1 which link members at their other ends are pivotably connected to a respective lever 6a and 6b.
  • These levers 6a and 6b are in turn pivotably supported and rigidly fixed to separate pivot shafts 7a and 7b, respectively.
  • the pivot shafts 7a, 7b are supported in a frame 27 which is bolted to the ceiling of a room.
  • the pivot shafts are vertical. However, as mentioned below, they can be inclined.
  • the vertical pivot shafts 7a and 7b have transmission members 8a and 8b which for transmitting a rotating movement to the pivot shafts engage corresponding transmission members 9a, 9b of a shaft 10.
  • the shaft 10 includes a worm of a worm gear 12 the input shaft of which is coupled to a motor 13 which may be pneumati- caly or hydraulically driven, but is preferably electrically driven.
  • transfer means for parallel movement of the carrier bar 1 in its lateral direction.
  • Said transfer means including drive means and transmission means is provided to drive said pivot shafts 7a and 7b in oposite rotational directions.
  • Said transfer means includes two transfer assemblies interconnected by means of said drive means and transmission means.
  • the two transfer assemblies are similar, the compoinents thereof having identical lengths and structure.
  • the length of the carrier arm 1 is equal to the distance between the pivot shafts 7a and 7b.
  • levers 6a and 6b have the same longitudinal extensions and so when rotating the pivot shafts 7a and 7b in opposite directions the carrier arm 1 will be transferred perpendicularly to its longitudinal extension. From an initial lifting position where the levers 6a and 6b are parallel and facing in the same direction the levers can be rotated either inwardly or outwardly thereby achieving the same lifting action on the carrier arm 1.
  • connection of the link members 5a and 5b to the carrier arm 1 has such a structure that the link members can pivot around an axis essentially perpendicular to the longitudinal extension of the carrier arm which axis is horizontal when the lifting device is mounted in place.
  • a shaft 17 (Fig. 2B) is used for this connection, thereby counter-acting the tendency of lateral swinging of the load receiving means.
  • Another suitable articulation for this connection is a universal joint, such as a ball and socket. Such an articulation also allows movement between the link members 5a and 5b and the carrier arm around an axis parallel to the carrier arm and so lateral swinging motion of said load receiving means will not be counter-acted.
  • connection of the link members 5a and 5b to the respective levers 6a and 6b is constructed for allow pivoting movement around both a vertical and a horizontal axis perpendicular to the carrier arm.
  • a suitable articulation in this case is a universal joint, such as a ball and socket (Fig. 3).
  • a vertical pivot 19 can be pivotably mounted at the end of the respective lever 6b facing away from the associated pivot shaft which pivot at its lower end has a lateral through shaft 16 which is connected to the associated link member 5b. This latter articulation with rigid shafts counter-acts unfavourable swinging motion of said load receiving means.
  • the transmission between the output shaft 10 of the worm gear 12 and the two pivot shafts 7a and 7b can be constituted in any different ways.
  • these transmissions are preferably embodied as bevel drives 8a, 9a and 8b, 9b respectively, the shafts 10, 7a and 7b being supported and carried in bearings in a suitable manner.
  • the gear reduction between the shaft 10 and the pivot shafts 7a and 7b preferably is 2:1 in order that the load on the levers 6a and 6b is kept at reasonable values when operating the lifting device.
  • the drive means and transmission means described above sometimes may be too heavy to be fixed to the ceiling of rooms in older buildings. A considerably lighter drive means and transmission means (not shown) can be made using a chain drive.
  • the transmission can include sprockets fixed at the ends of each pivot shaft 7a, 7b which sprockets are rotatable in different directions by means of an endless chain having a figure-of-eight configuration.
  • a central sprocket fixed on an additional shaft engages the chain and said shaft is driven by a gear connected to a motor.
  • the levers 6a and 6b are rigidly fixed to a respective pivot shaft 7a and 7b and extend downwardly therefrom under an angle of declination which is less than 90°.
  • the levers can form any angle to the pivot shafts and also extend upwardly therefrom.
  • Fig. 1 the transfer means of the lifting device is shown entirely over the carrier arm and is mounted to the ceiling of a room by means of the frame 27 (see also Fig. 3).
  • said transfer means and the associated frame can be mounted on the floor of a room, the pivot shafts 7a and 7b thereby extending upwardly from the floor.
  • This latter alternative embodiment is of interest only in the case of ample space in the room where the lifting devise is placed.
  • the levers can however only be rotated inwardly in order that the carrier arm 1 shall be able to pass through its to position, in which the levers are directed towards each other and located in the same vertical plane.
  • the carrier arm should be somewhat shorter than the distance between the pivot shafts 7a, 7b since otherwise the latter will obstruct the carrier arm when passing through its top position.
  • the lifting device For lifting and transferring between two supporting surfaces a patient supported in said receiving means 2 the lifting device is put into a position where the levers 6a and 6b are parallel and the link members 5a and 5b are essentially vertical.
  • the bed or similar resting place on which the patient to be lifted lies is inserted under the carrier arm 1 so that the latter takes a position along the person in question. Then the person is placed in said receiving means 2 and the lifting device can be activated.
  • the shafts 7a and 7b will rotate in opposite directions, e.g. so that the levers 6a and 6b are pivoted outwardly from the carrier arm as shown in Fig. 1.
  • the carrier arm During the movement of the carrier arm from its bottom position to its top position (rotation of the pivot shafts over 90°) where the levers 6a and 6b are located in the same vertical plane, the carrier arm describes a curve.
  • the car- rierarm When the rotation of the shafts are continued over another 90° the car- rierarm performs a reverse movement downwardly to a laterally displaced second bottom position, the carrier arm thereby describing a curve which in relation to a vertical plane through the two pivot shafts 7a and 7b is symmetrical with said first mentioned curve.
  • a biasing device 15 is provided between two members 11 a, 11 b fixed to the pivot shafts 7a and 7b.
  • the biasing device 15 may be shaped as a tension spring which has its most biased or extended state when the carrier arm takes any of its bottom positions.
  • the biasing device 15 is a tension spring said members 11 a, 11 can be either rigid arms or cables be wound around the pivot shafts.
  • the biasing device 15 is completely unloaded when the levers 6a and 6b are situated in the same vertical plane, i.e. when the carrier arm 1 takes its top position.
  • the biasing device When operating the lifting device the biasing device will contribute to the rotation of the pivot shafts during the lifting stage while during the lowering stage the biasing device will smooth the movement at the same time as a bias is built up in the biasing device.
  • biasing device 15 can be embodied in a variety of ways. Thus, it may also be hydraulic or penumatic.
  • Fig. 3 illustrates a preferred embodiment of the lifting device.
  • the same reference numerals are used as in Fig. 1 and 2 for denoting the same components.
  • the carrier arm 1 has two side members 1 a and 1 which are rigidly connected by means of cross members.
  • One cross member at each end of the carrier arm serves as a horizontal shaft 17 for the respective link member 5a, 5b for connecting the same to the carrier bar.
  • the link members 5a and 5b are connected at their upper ends to a respective lever 6a, 6b by a ball and socket articulation 18.
  • the upper-portions of the pivot shafts 7a and 7b are accommodated in a casing 14 together with theworm gear 12, the motor 13andthe biasing device 15.
  • the carrier bar 1 is shorter than the distance between the two vertical pivot shafts 7a and 7b.
  • Fig. 4A illustrates the lifting device in a position where the levers 6a and 6b are rotated outwardly at a relative angle of 180° in which position the carrier arm 1 takes its top position.
  • Fig.4B the lifting device is illustrated with the carrier arm 1 in its bottom position and the link members 5a and 5b are parallel and vertical. In this bottom position the two levers 6a and 6b are directed towards each other from the respective pivot shafts.
  • the relative lengths of the carrier arm 1 the link members 5a and 5b and the levers 6a and 6b are defined such that the link members take up a paral- lell position (bottom position of the carrier arm) when the two levers 6a, 6b from a mutually parallel position have been rotated inwardly towards each other by a small angle, substantially 20°.
  • the lifting heigh will be greater than for the embodiments shown in Figs. 1 and 3.
  • the two pivot shafts 7a and 7b are rotated counter-clockwise and clockwise, respectively (seen from above), the levers 6a and 6b thereby lifting the carrier arm 1 via of the link members 5a and 5b.
  • the carrier arm 1 principally performs a movement upwardly while its movement in horizontal direction is small.
  • the distance between the pivot shafts 7a and 7b is 80 cm
  • the length of the levers 6a and 6b is 65 cm
  • the length of the link members 5a and 5b is 80 cm
  • the length of the carrier arm 1 between its connecting points to the link members is 60 cm
  • the angle a between the levers and the pivot shafts is 80°.
  • the carrier arm 1 can be longer than the distance between the two vertical shafts.
  • the carrier arm takes its bottom position when the two levers are turned outwardly from each other.
  • the pivot shafts are first pivoted in a direction towards each other until they are parallel and after continued movement they come into the same vertical plane, in which position the carrier arm takes its top position. Then the levers are brought out on the other side of the lifting device and the reverse movement is obtained, i.e. the carrier arm is lowered.
  • pivot shafts 7a and 7b need not be exactly parallel to each other.
  • the pivot shafts can be arranged in the same vertical plane with their bottom ends located at a greater distance from each other than their upper ends, thus having a slight inclination to the vertical. This arrangement can be used when the carrier arm is shorter than the distance between the points on the pivot shafts from where the levers extend.
  • the pivot shafts can also be arranged in the same vertical plane with their bottom ends located at a smaller distance from each other than their upper ends. This arrangement can be used when the carrier arm is longer than the distance between the points on the pivot shafts from where the levers extend.
  • the bearings of the pivot shafts as well as their transmissions will be more complicated than in the embodiments of the lifting device shown in Figs. 1 to 4B.
  • the above described embodiments of the lifting device are relatively sensitive to unsymmetrical load, namely the condition where the centre of gravity of the load is displaced from a vertical plane of symmetry across the carrier arm.
  • the carrier arm will tend to incline relative the horizontal plane and the lifting device will not operate satisfactorily.
  • a stabilizing means 20 shown in Fig. 5 is provided in order to counteract said inclining tendency of the carrier arm.
  • Said stabilizing means 20 includes two rigid bars 21 a and 21 b which at their ends are pivotably connected between the link members 5a and 5b in a crossing relation.
  • Stabilizing means 20 shown in Fig. 5 is arranged between the bottom ends of the link members, and the carrier arm 1 is suspended between spacers 22a and 22b under said stabilizing means.
  • the stabilizing means 20 also can be connected to the link members at a distance from their bottom ends and so it may simply be mounted on the above described embodiments of the lifting device.
  • Said stabilizing means 20 comprises U-shaped clevises 23a, 23b having oposite lugs and a connecting web the latter being rigidly fixed to the respective link members 5a and 5b at the lower ends thereof such that the clevises open up towards each other.
  • the bars 21 a and 21 b are disposed in parallel vertical planes and have their ends inserted between the lugs of a respective clevis 23a, 23b where they are pivotably supported by means of horizontal shafts. From Fig. 5 it is seen that the bars 21 a and 21 b are symmetrically arranged such that the bar 21a a at one end is mounted below the bar 21 b but at its other end is mounted over the bar 21 b, the corresponding relation applying to the bar 21 b.
  • the upper ends of the spacers 22a and 22b which are connected to the clevises have two legs which reach around the associated clevis 23a and 23b, respectively.
  • a horizontal shaft through the legs and the clevis allows the necessary rotation between the link members and the carrier bar 1, in this case the spacers.
  • the stabilizing means 20 in that a couple of forces is transmitted over the clevises and the bars 21a a and 21 b for urging the lower end of the link member 5b down to the same level as the lower end of the link member 5a.
  • the link members 5a and 5b will be maintained at the same level of- height and the carrier arm will be horizontal.
  • the corresponding conditions hold if instead the lower end of the link member 5b is subjected to a greater load than the lower end of the link member 5a.
  • said stabilizing means 20 can be constructed in several other ways as long as it includes elements coupled to the link members which elements in response to loads on the link members transfer from each link member to the other link member a force corresponding to the difference in the load.
  • each connecting member 24a and 24b of the spacers for connecting the respective spacer to the carrier arm consists of a cylindrical sleeve having a bearing, preferably made of tetrafluoro-ethylene, which allows the carrier arm to be rotated around its own axis.
  • the carrier arm From the two ends of the carrier arm wide bands or belts 25a and 25b, e.g. of plastic material, extend downwards for supporting said load receiving means (not shown) having a suitable structure, e.g. of that kind shown in Fig. 3 where the belts 25a and 25b also are shown.
  • the belts 25a, 25b have a suitable length such that the individual lifting bands 4 of said load receiving means reach the desired height level when the carrier arm takes its bottom position.
  • the lifting device has been described above in connection with a load receiving means 2 suited for lifting a person confined to bed or having reduced faculty of motion.
  • any type of load receiving means can be connected to the carrier arm in order to lift and/or transfer other types of loads.
