In order to improve the bending strength of the lifting beams, the lifting beams are surrounded by two telescopic tubes, one of the tubes being fixed to the outer end of the telescopic first lifting beam and is slideable on the second telescopic tube, which extends inwardly on the second lifting beam.
FIELD OF THE INVENTION This invention relates to an arrangement at at least two telescopically protrudable lifting beams, which are loaded in their protruded position and which are driven in an optional way from a retracted position to a protruded position.
BACKGROUND OF THE INVENTION Lifting beams of this type are used, e.g. within the medical service for lifting means, when a person is being lifted from a sitting position to a standing position or from one place to another. Telescopic lifting beams of this kind are also used for other lifting purposes for patients.
SUMMARY OF THE INVENTION It has now shown, e.g. within the medical service, that the lifting beams unintentionally have been loaded by bending when the telescopic beams are in their protruded position in relation to each other, which have lead to that the outer lifting beam has been bent in the area where it protrudes out of the outer end of the first lifting beam. The object of the invention is to increase the strength of the lifting beams when they are in their protruded position and that this is accomplished by simple means, which are cheap. The reinforcement is easy to apply on existing lifting beams without any complicated amendments of their design.
BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of the invention will now be described by reference to the drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The arrangement shown in FIGS. 1 and 2 comprises a first lifting beam 1, which is telescoping in a second lifting beam 2, being fixed to a driving means 3 which displaces the first lifting beam 1. The driving means 3 can be any known engine as e.g. a hydraulic engine or a gear motor, which drives the lifting beam 1 telescoping in the lifting beam 2. The lifting beams are loaded when the lifting beam 1 is protruding out of the lifting beam 2 in the position shown in FIG. 1. The lifting beams 1 and 2 are surrounded by two telescopic tubes 4 and 5, the first telescopic tube being displaceable over the second telescopic tube 5. FIG. 1 shows that the telescopic tubes 4 and 5 are in their most protruded position while FIG. 2 shows that the telescopic tube 4 is retracted on the second telescopic tube 5 over half of the length of the second telescopic tube 5. The first telescopic tube 4 is fixed to the outer end 6 of the first lifting beam 1 by an attachment 7. The telescopic tube 4 has a first coupling part 8 at its inner end, see FIG. 3. The second telescopic tube 5 has a second coupling part 9 at its outer end, see FIG. 3. The two coupling parts 8 and 9 work in such a way that when the telescopic tube 4 is moving with the telescoping beam 1, the coupling part 8 is hitched by the coupling part 9 so that the second telescopic tube 5 follows the first telescopic tube 4. When the telescopic tube 4 moves in the opposite direction, the coupling part 8 moves away from the coupling part 9 and the second telescopic tube 5 is pushed inwards on the second lifting beam 2 by that the attachment means 7 will abut the outer end of the second telescopic tube, see FIG. 3.
