Definitions

  • the invention concerns a lifting tower comprising a car ⁇ riage for the mounting of handling tools, said carriage having rotable elements in the form of ball bearings, wheels, rollers and the like mounted in each end of the carriage, and a first profile, also the use of the lift ⁇ ing tower.
  • the known lifting towers which are used in this connection comprise a carriage/a telescopic piece which can slide in a single profile piece.
  • Such a mobile person lifter is known, for example, from EP-A-0, 236,284 and DE-A-3504972.
  • a lifting tower of the kind dis ⁇ closed in the preamble and where a lifting tower also comprises a second profile lying parallel with the first profile, said profiles being disposed opposite each other, and in which profiles the rotating elements for the carriage are placed.
  • the carriage which must be moved up and down in the lifting tower is mounted in two profiles lying op ⁇ posite each other, a greater torsional stability is achieved during operation, and also a more rigid system which need not be dimensioned as strongly as is known from other systems, and which moreover can be produced in lighter materials. Furthermore, it functions in a self- stabilizing manner when exposed to stress, in that the profiles, for example during the lifting of a heavy load, will be pressed in towards each other and are pressed towards the carriage, which increases the stability of the construction, in that the two bending moments are directed towards each other. This is the opposite of that of the known systems, where the carriage will be bent in the profile itself and also transfer a bending force to the profile. As a consequence of the self-stabilization achieved with the construction according to the in ⁇ vention, jolting and noise will be minimal.
  • this groove not only faces away from the patient but also comprises two surfaces.
  • the invention also concerns the use of a lifting tower, where it is envisaged that this is used primarily on mobile or stationary person lifters as disclosed in claim
  • a mobile person lifter is thus understood to be where the lifting tower is placed on a movable under-frame, so that the lifting tower can be brought to wherever the patient may have use for it. This can be to a toilet/- shower area or it can be in connection with the removal of a patient from a bed.
  • the lifting tower can also be envisaged for stationary use, i.e. where it is mounted either on the floor, the ceiling or a wall, and in this connection is used in rooms where a certain function is undertaken again and again.
  • fig. 1 shows a lifting tower seen in section from the side and mounted on a mobile underpart
  • fig. 2 shows a cross-section of the carriage with securing elements mounted
  • fig- 2a shows a second example embodiment of a lifting tower seen in section through the carriage and with a securing element mounted
  • fig. 3 shows an enlargement of the carriage part from fig. 1,
  • fig. 4 shows the lower mobile underpart from fig. 1 in detail
  • fig. 5a shows a stylized, mobile lifting apparatus seen from the rear
  • fig. 5b shows the stylized, mobile lifting apparatus in fig. 5a seen from the side
  • fig. 6 shows a second cross-sectional drawing of a second embodiment of the carriage according to the invention.
  • Fig. 1 shows a lifting tower 1 consisting of a centre part, a spindle 9 on which a carriage 4 mounted with rotating elements 7 is disposed, said rotating elements in the form of ball bearings, wheels, rollers or the like being housed in a first C-profile 2 and a second C- profile 3, said C-profiles comprising a part of the lift ⁇ ing tower 1.
  • the C-profile is characterized by having three surfaces which are closed, and the fourth surface being wholly or partly open, in that in this opening there is passage for connection elements for the carriage 4 or also for the end surfaces of the carriage itself.
  • Each profile comprises at least one wall parallel with the axis of the rotating elements.
  • the two oppositely-lying C-profiles 2, 3 are fastened to each other at the top and the bottom by means of plates 24 which are either secured or welded to the profiles.
  • a carriage 4 is understood to be that part which supports the handling tool, and which is movable in the upwards and downwards direction in the lifting tower 1.
  • the lifting tower 1 is seen mounted on a mobile underpart 19 which is provided with wheels 23.
  • the lifting tower 1 is expediently fastened to the underpart 19 by means of nuts 25, in that this makes a mobile lift easier to transport, since the lifting tower and the underpart can thus be assembled in situ.
  • the two C-profiles 2 and 3 are fastened to each other at the top and the bottom, or in the upper and the lower part of the lifting tower by means of plates 24 which are welded to the ends of the two C-profiles.
  • the profiles are thus parallel with each other and lie opposite each other.
  • a cross-section of the lifting tower 1 with carriage 4 is seen in fig. 2 and fig. 2a, which show two oppositely- lying C-profiles 2 and 3, between which the carriage 4 is disposed.
  • the carriage 4 is a square or rectangular box open at both ends, i.e. at the top and the bottom for the passage of the spindle 9, and is made of aluminium or steel, and which is connected to the two C-profiles by means of flanges or plates which terminate in the C- profiles, and through the end parts of which there ex ⁇ tends an axle 6 having rotating elements 7 in the form of wheels, ball bearings or the like mounted on its ends.
  • the carriage 4 can, however, also be welded directly on the axles 6, and where the rotation thus takes place between the axle 6 and the rotating element 7.
  • each C- profile there is thus disposed four rotating elements 7.
  • the C-profiles can have different configurations. There can be special cutouts, and there can be reinforcements provided in the profile.
  • the rotating element 7 itself can be cut off at an angle, and a corresponding inclined surface can be formed in the C-profiles 2, 3, thus providing the rotating elements with a higher degree of support and the prevention of jolting in the tower.
  • the end surfaces of the rotating elements which are in contact with the inner surfaces of the C-profiles, to be provided with a friction-free coating, for example teflon 14, in order to reduce the friction.
  • a friction-free coating for example teflon 14
  • the side surfaces 27 of the carriage 4 lie between the two C-elements.
  • to these side surfaces 27 there can be welded metal plates 16 at right angles and in the longitudinal direction away from the actual carriage.
  • On the ends of these metal plates 16 there are welded tubular elements 17 which are hollow, so that handling tools in the form of lifting arrangements, slings, canvas and the like can be mounted in these elements.
  • the handling tool can also be fastened to a U-section 16 which is similarly fastened to the side surfaces 27 along each its longitudinal part of the U, but on the forward- ly-directed surfaces of which there are welded fixing elements for the handling tool 17 . This results in another and more expedient loading of the system.
  • the "auxiliary tool" can be a horizontal table plate, and where the lifting tower it ⁇ self can possibly be mounted on that frame which comprises parts of the table, or merely on a stand-plate.
  • Fig. 3 is a detail drawing of the carriage seen from the side, and shows the two C-profiles 2, 3 opposite each other with a carriage 4 arranged between them, said car- riage 4 being a rectangularly extending tube with a plate 27 mounted on its upper and lower surfaces, said plates entering into the opening in the C-profiles and having a hole in the front part through which the axle 6 extends for the mounting of the rotating elements 7.
  • the spindle 9, which rotates in the nut 10 extends for the full extent of the lifting tower 1.
  • the tubular element 17 for the mounting of tools will also be seen to extend vertically from the upper to the lower part to an extent which corresponds to the vertical extent of the carriage.
  • the tubular element 17 is fixed to the carriage 4 by means of flat tubes 16.
  • the lifting tower 1 can be expedient to mount the lifting tower 1 on a mobile underpart 19, and as shown in more detail in fig. 4.
  • the lifting tower 1 is mounted on the under-carriage 19 by means of bolts, nuts or screws 25.
  • the lower part itself also comprises a leg-spreading mechanism 29 for the adjustment of the wheels 23 which are placed in pairs opposite each other, so that the distance between the wheels can be increased, herewith increasing the stability of the mobile lifting tower.
  • a baseplate 30 Under the spindle 9 there is provided a baseplate 30 below which a motor 15 is mounted, and which effects rotation of the spindle.
  • the spindle 9 and the motor 15 are coupled together in a commonly-known manner by means of a coupling 13.
  • the under-carriage 19 is suitably covered with plates 28, so that the motor and leg-spreading mechanism etc. lie concealed.
  • a stylized version of a mobile lifting arrangement consisting of an under-carriage 19 on which a lifting tower 1 is mounted, is shown as seen from the rear in fig. 5a and seen from the side in fig. 5b.
  • On the lifting tower 1 there is a handle 32 for better control of the lift.
  • the spindle 9 which is covered by rubber flaps or brushes 5, between which there is a slot 33 in which the securing element's flat plate part 16 can slide.
  • a tool 18 in the form of a yoke is provided in the tubular element 17, said yoke extending in a double-sided manner, in that ac- cording to the invention there are two oppositely-lying tubular elements 17 in which the yoke can be mounted.
  • a box 31 is seen mounted on the rear of the carriage, this box containing batteries, control items and the like.
  • the spindle itself is suspended in an upper housing 12, which will now be described in more detail with reference to fig. 1.
  • the spindle is fastened to a plate 34 which rests on a bearing 35, preferably a ball bearing, on the upper side of the plate.
  • the spindle is thus suspended from the top, whereby the forces which arise in the lifting tower and are transferred as pressure forces on the ball bearing 35 give rise to tractive forces in the spindle 9.
  • this is an unusual assembly, in that the spindle 9 is usually mounted at the bottom, so that the bearing which is exposed to pressure forces is also provided at the bottom, and whereby the spindle is thus exposed to pressure forces.
  • the advantage of having tractive forces on the spindle is that the spindle thread is thus not pressed together, but rather drawn apart, which results in a better sliding of the carriage when this moves up and down, and also with less noise and without the jolting which is otherwise commonly known. Moreover, the spindle can be of smaller dimensions.
  • fig. 6 shows a second cross-sectional pos ⁇ sibility for the carriage 4 and the profiles, and shows reinforcement ribs 36 inside the actual C-profile, which makes the C-profile more stable.
  • the cross-section is shown without connection elements 16, 17.
  • These rein ⁇ forcement ribs 36 can also be disposed in such a way that to a higher degree they lie up towards the rotating ele- ments 7, with the result that these extend in a more stable manner.
  • the axle 6 can also be welded directly to the carriage instead of using the earlier mentioned plate connections 27.
  • the rubber flaps 5 can be mounted with a thickened part in a groove provided for this purpose on the inner surfaces of the C- profiles.
  • the C-profiles can be expediently configured in aluminium, but can also be made of steel and other materials.
  • the advantage of aluminium, however, is that this is a lighter material, and due to the double C- profile a choice of material comprising aluminium is suf ⁇ ficiently strong, unlike the known constructions where use is made of steel or consequently over-dimensioned contructions in light alloys.
  • the dimensions of the lifting tower will, for example, be 120-140 mm x 120-140 mm, where the breadth of a C-profile will be 50 mm and the distance between two C-profiles about 40 mm.
  • the carriage 4 itself can be configured in many ways, e.g. as an elongated square or rectangular profile piece which is wholly or partly open in the "bottom” and “cover”, and where in the upper and lower parts there are mounted four wheels, i.e. eight in all, which roll in pairs in each their profile piece 2, 3.
  • the carriage can also be configured so that each upper and lower piece is box-shaped and with the wheels mounted, and where the up- per and lower piece is connected with a profile piece with another shape and other dimensions. The distance thus created between the upper and the lower set of wheels optimizes the stability.
  • the drive mechanism for the upwards and downwards move ⁇ ment of the carriage in the lifting tower i.e. the spindle system described, can be replaced by other systems, e.g. mechanisms which are driven hydraulically.
