Definitions
- This invention relates to an arrangement at at least two tele- scopically 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.
- 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.
- the lifting beams are normally loaded in their longitudinal direction and they are designed to meet such a load.
- the lifting beams can be driven hydraulically via gears or manually using rope-driving means or with the help of a crank means.
- 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 inven- tion 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.
- Fig. 1 is hereby a side view, partly in a longitudinal section, of two telescopic lifting beams in their protruded position.
- Fig. 2 is partly a longitudinal section of the telescopic beams in their retracted position.
- Fig. 3 is a longitudinal section of an area depicted by the arrow A in fig./" .
- the arrangement shown in fig. 1 and 2 comprises a 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.
- the second telescopic tube 5 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 means of a means of an at- tachment 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 tele- scopic 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.
- a bearing ring 10 attached to the outer end of the second telescopic tube 5.
- the inner periphery of this bearing ring contacts the outside of the first lifting beam 1 and slides along the lifting beam 1.
- the lifting beam 2 has a bearing tube 11 at its outer end, the second telescopic tube 5 slides on the bearing tube 11.
- the second telescopic tube 5 has a bearing ring 12 at its inner end, which bearing ring slides with its inner periphery edge on the lifting beam 2.
- the second telescopic tube 5 When the arrangement is in the position shown in fig. 1, the second telescopic tube 5 will act as a support for the lifting beam 1 via three points .
- the first support point is in the area shown by arrow A
- the second support point is in the area of the bearing tube 11
- the third support point is at the area of the second bearing ring 12.
- the lifting beam 1 will be reinforced against bending in the area of the tube 11.
- the invention has been described above in connection with two telescopic lifting beams but the same reinforcement means can be arranged for e.g. three telescopic lifting beams.
- Fig. 1 the telescopic tube slides with half of its length on the lifting beam 2.
- Fig. 1 also shows that the length of the first telescopic tube is about half the length of the first lifting beam in its protruded position while the second telescopic tube 5 has a length which corresponds to about half of the length of the second lifting beam 2.
- the length of the telescopic tubes may of course be arranged to what is needed but the important is that the second telescopic tube is of such a length that it supports the outer lifting beam at a point which is far away from the outer end of the inner lifting beam 2.
