Abstract
Description
- The invention relates to nursing beds more particularly to adjustable beds of the type normally used in hospitals or old people's homes and also by particular for nursing invalids or sick persons.
- Such beds are wellknown but generally have embodied complicated mechanisms which add considerably to the cost of the bed as for instance electrical motors or present maintenance problems as hydraulic systems.
- Some systems have been developped which use counterbalancing springs..For instance the Dutch specification 71 05 381 relates to an adjustable height bed but it had not found acceptance because the system is too expensive to manufacture. The US
patents 3 039 118 and 2 698 442 describe hospital beds in which counterbalancing springs are located in the legs of the bed. The action of the.springs are coordinated by cables or a locking system acts on two legs at the end of the bed. In the first case the bad is only adjustable in height and in the second case the bed can also be tilted but only in a longitudinal direction. - An other drawback of those constructions is the use of mechanical springs. As a matter of fact the strength of the spring is maximal when full compressed but becomes to be inefficient after a short way.
- The principal object of the present invention is to provide an improved and pratical nursing bed construction in which the height and tilting of the mattress support may be easily-achieved.
- An other object of the invention is to provide a very simple nursing bed construction in which the tilting of the mattress support may be easily achieved around an infinity of axis.
- An other object of the invention is to provide an improved adjustable height and tilting nursing bed which may be simply and inexpensively produced.
- To achieve these objects, the nursing bed of the present invention which comprises a mattress support and at least.two telescopic legs is provided with gas springs mounted between the sliding parts of the legs, with locking means and releasing means for the gas springs.
- So mounted, the gas springs which can work independently one from the others counterbalance the weight of the mattress support and the weight of the patient. The locking means acting on each gas spring allow to obtain for the mattress support a predeterminated position chosen among an infinity of height and tilting positions. The releasing means allow the nurse to modify the position of the mattress support without effort.
- The invention will be better understood and still further objects and advantages will become apparent from the following description of the prefered embodie- ment with reference in the drawings which are part of the invention and in which :
- - Figure 1 is a perspective view of a nursing bed with telescopic legs,
- - Figure 2 is a cross-section view of one of the legs of the nursing bed embodying the invention,
- - Figure 3 is a cross-section view of a gas spring provided with calibrating means according to the inventibn,
- - Figure 4 is a cross-section view of one of the legs of the.nursing bed, embodying the invention in which the gas spring is provided with valve system locking means,
- - Figure 5 is a side elevation view of joined up releasing means according to the invention and
- - Figures 6, 7 and 8 are schematic views of some of the.possibleways.of joining up the releasing means.
- As illustrated on figure 1, a nursing-bed comprises a
mattress support 1 and four telescopic legs with slidingparts - Such nursing bed is wellkmown as described, for instance, in the
French patent 1 168 393. In this patent, the avthor recommends the use of a lifting jack to counterbalance the weight of the patient. Thus the use of this bed is not easy and presents the same drawbacks than above cited patents - According to the invention a
gasspring 5 is provided between sliding parts. 2 and 3 of each telescopic leg. So when the locking mean 4 isunlocked gasspring 5 tends to raise the support mattress against its and patient weight. If well chosengasspring 5 allow the nurse to lift or lower the bed without effort. - According to the fact that each gasspring works independently and in a continuous way, it is possible to obtain an infinity of height and tilting positions. In particulair, tilting may occur around a longitudinal axis, or transversal but also around any other axis between the two precited at right angle axis. In fact, potential patients in hospitals may have very various size ahd weight.
- The figure 3 shows a gasspring provided with calibrating means adapted to counterbalance the difference of weight of potential patients. This gasspring presents a
cilinder 7 defining an in_erchamber 8 filled with compressed gas so as to push awaya piston 9 slidingly located in thecilinder 7. At the end of thecilinder 7 located opposit to the active piston 9 is provided anadjustable piston 10 which allows to modify the compression of the gas inchamber 8. Underpiston 10 are fixed twolegs 11 between the extremities of which is weld anut 12. Under thecilinder 7 is located a milled headedscrew 13 which cooperates with the nut.12. - A
clip 14 preventspiston 10 to be pushed out ofcilinder 7 by compressed gas.. By turningscrew 12piston 10 slides incilinder 7 modifying the volume ofchamber 8 thus modifying the compression.of gas withinchamber 8. To preventpiston 10 to rotate withscrew 12, aguid system stang 17 of the active.piston as it can be seen in figure 4. With such a system may be used releasing means as shown in figure 5. Releasing means compriselevers 19 pivoted onmattress support 1 by means ofaxles 20.Lever 19 comprises aflat portion 21 adapted to push oncontrol mean 18 and aprehension portion 22 extending away fromlever 19. The advantage of these levers consists in the fact that they may be joined up so as to act on two or more locking means. For instance, it may be seen in figure 5 that raising theprehension position 22 of lever A will also raiseprehension 22 of lever B andflat portion 21 of lever A will.lowerflat position 21 of lever C theprehension portion 22 of which will raiseprehension portion 22 of lever D. By judicious positioning of levers it is possible to act on 1, two or all of gassprings as it may be seen in figures 6,7 and 8 in which levers noted A to H act on gassprings noted 1 to 4 as reported in tables. - It is evident that many other dispositions may be adopted and the preferred embodiments shown in figures 6 to 8 have been given as examples and do not constitute a limiting list.
