Opfindelsen angår en kombineret dreje- og ståseng af den i krav l's indledning angivne art. En sådan seng kendes fra CH-patentskrift nr. 615.586.The invention relates to a combined swivel and bar bed of the kind specified in the preamble of claim 1. Such a bed is known from CH Patent No. 615,586.

5 I sygehuse, plejeinstitutioner og private hjem anvendes ved pleje af fysisk stærkt hæmmede og svage patienter senge, der kan indstilles i sengens tværretning, dvs. hvad angår rygdelen. Indstillingen af sengen i tværretningen medfører den fordel, at patientens krop kan bringes i en 10 ændret liggestilling. De herved anvendte senge kan bringes i en høj stilling såvel i stillinger med hoved- eller fodenden sænket med maksimalt 16°.5 In hospitals, nursing homes and private homes, the care of physically severely impaired and weak patients uses beds that can be adjusted in the transverse direction of the bed, ie. as for the back part. The adjustment of the bed in the transverse direction gives the advantage that the patient's body can be brought into a changed position. The beds used can be placed in a high position as well as in positions with the head or foot end lowered by a maximum of 16 °.

Som nævnt ovenfor kendes også en seng af den i krav 1' s indledning angivne art fra CH-patentskrift nr. 615.586.As mentioned above, a bed of the kind specified in the preamble of claim 1 is also known from CH Patent No. 615,586.

15 Endvidere er det kendt, med henblik på at gøre det lettere for en patient at komme ind i og ud af sengen, jf. US-patentskrift nr. 3.875.598, at bringe en hospitalssengs liggeflade i en skrå stilling ved svingning om en vandret længdeakse.Furthermore, in order to make it easier for a patient to get in and out of bed, cf. U.S. Patent No. 3,875,598, it is known to bring a hospital bed to an oblique position by pivoting about a horizontal longitudinal axis.

20 Desuden er der, jf. DE-fremlæggelsesskrift nr. 2.756.154, blevet foreslået en indretning til sidehævning af sengeliggende sygehuspatienter, idet der på en sygehusseng påsættes en rektangulær ramme, hvis tværstykker i midten ved hjælp af to løfteindretninger er svingeligt forbundet med 25 tværstykkerne i sygehussengens madrasramme, og ved enderne er udløseligt ledforbundet med sidstnævnte tværstykker. Udgangspunktet for denne indretning er, at de i længderetningen opdelte senge, der anvendes i sygehusvæsenet, er særdeles kostbare, idet det ved hjælp af denne kendte ind-30 retning er muligt uden store omkostninger at omdanne enhver normal sygehusseng til en sådan "svingeseng".20 In addition, according to DE presenting application no. 2,756,154, a device has been proposed for raising bedside hospital patients, in which a rectangular frame is mounted on a hospital bed, whose crosspieces in the middle are pivotally connected by means of two lifting devices. the cross sections in the mattress frame of the hospital bed, and at the ends are releasably articulated with the latter cross sections. The point of departure for this device is that the longitudinally divided beds used in the hospital system are extremely expensive, with the aid of this known device it is possible to transform any normal hospital bed into such a "swing bed".

Derudover er de for tiden kendte sengetyper konstrueret med henblik på anvendelse med syge patienter i almindelig- DK 167205 B1 2 hed, og omfatter ikke særlige indretninger med henblik på pleje af fysisk stærkt hæmmede og svage patienter.In addition, the currently known bed types are designed for use with sick patients in general, and do not include special devices for the care of physically severely impaired and weak patients.

En indstilling af sengen i længderetningen ville imidler-5 tid medføre den fordel, at patienten kan drejes gennem 90®, således at patienten ligger på siden og kan plejes og vaskes.Longitudinal adjustment of the bed would, however, have the advantage that the patient can be rotated through 90 ° so that the patient is lying on the side and can be nursed and washed.

Det er på denne baggrund opfindelsens formål at forbedre en seng af den indledningsvis nævnte art med henblik på at 10 muliggøre en indstilling af rygdelen en indstilling af liggefladens langsgående del, en indstilling af liggefladens hældning indtil lodret, og 15 - en højdeindstilling af liggefladen, hvorved de forskellige indstillinger kan udføres samtidigt eller efter hinanden og trinløst. Derudover skal sengen omfatte elektromotoriske indstillingsorganer med henblik på at undgå, at plejepersonalet eller patienter, som selv 20 indstiller sengen, udsættes for store belastninger.Accordingly, it is an object of the present invention to improve a bed of the kind mentioned above, in order to enable an adjustment of the back portion, an adjustment of the longitudinal portion of the reclining surface, an adjustment of the inclination of the reclining surface to the vertical, and a height adjustment of the reclining surface, whereby the various settings can be performed simultaneously or in succession and steplessly. In addition, the bed should include electromotor adjusting means to prevent the caregivers or patients who themselves adjust the bed from being subjected to heavy loads.

Dette formål opnås ved en seng som tillige udviser i krav 1's kendetegnende del angivne træk.This object is achieved by a bed which also exhibits the features specified in claim 1.

Ved en sådan udformning af sengen opnås, at det er muligt uden anstrengelser at udøve en fuldstændigt trinløs og 25 samtidig indstilling af sengen i de forskellige frihedsgrader. Heraf kan følgende muligheder nævnes: 1. En højdeindstillelighed mellem 40 og 80 cm, 2. sengens liggeflade kan bringes i en stå-stilling (ca.By such a design of the bed is achieved that it is possible without effort to exercise a completely stepless and simultaneous adjustment of the bed in the various degrees of freedom. Of these, the following options are mentioned: 1. A height adjustment between 40 and 80 cm, 2. The bed's lying surface can be brought into a standing position (approx.

90° med vandret), idet liggefladens nederste ende i så 30 fald berører gulvet, 3. mulighed for indstilling af en del af liggefladen gennem ca. 80° i forhold til vandret om en i sengens tværretning forløbende akse, der er anbragt inden for den ved hovedenden beliggende tredjedel af liggefla- 3 DK 16720S B1 den, 4. mulighed for indstilling af den i længderetningen opdelte liggeflade om en langsgående midterakse gennem 5 ca. 85° i forhold til vandret.90 ° with the horizontal), with the lower end of the lying surface touching the floor in 30 cases; 3. possibility of adjusting part of the lying surface through approx. 80 ° with respect to the horizontal about an axis extending in the transverse direction of the bed, located within the third end of the lying end at the head end, the 4. option of adjusting the longitudinally divided lying surface about a longitudinal center axis through 5 ca. 85 ° to the horizontal.

Muligheden for at indstille de enkelte dele af sengen og muligheden for at kombinere de forskellige indstillinger opnås ved en sådan konstruktion af sengen, at der findes et større antal kombinationer af positionerings- og juste-10 ringsmuligheder, og at opdelingen af de enkelte bevægelige dele er udført på en sådan måde, at positionsindstilling og justering kan udføres enkeltvis eller kombineret uden hindring for yderligere indstilling.The possibility of adjusting the individual parts of the bed and the possibility of combining the different settings is achieved by such a construction of the bed that there is a greater number of combinations of positioning and adjustment possibilities and that the division of the individual moving parts is performed in such a way that position adjustment and adjustment can be performed individually or in combination without any hindrance to further adjustment.

De enkelte bevægelser udføres trinløst og under anvendelse 15 af løftearme, vinkelvægtstænger, forbindelsesstænger og vippeakser, der står i forbindelse med et eller flere elektromotoriske drivorganer, såsom spindeldrev.The individual movements are performed steplessly and using lifting arms, angular bars, connecting rods and tilting axes which are connected to one or more electromotor drives, such as spindle drives.

Derudover er, for at udelukke menneskelige fejl, indstillingen blokeret ved hjælp af mikrokont akter for at 20 forhindre ikke-gennemførbare indstillinger; f.eks. kan de ved langsgående opdeling af liggefladen fremkommende lig-gefladedele kun indstilles, når hoveddelen befinder sig i sin neutralstilling.In addition, to exclude human error, the setting is blocked by micro-contacts to prevent non-feasible settings; eg. For example, the longitudinal division of the lying surface parts can only be adjusted when the body is in its neutral position.

Når sengens indstillingsmuligheder udnyttes fuldt ud, er 25 det muligt at bringe også fysisk stærkt hæmmede og svage patienter i en ønsket hjælpestilling. F.eks. kan en totalt lammet patient ved hjælp af den i længderetningen opdelte liggeflade vendes gennem 90°, hvad der kan gennemføres ved anvendelse af kun en enkelt håndkontakt. I den udstrækning 30 patienten endnu er i stand til at bevæge armene eller hænderne, kan patienten selv gennemføre denne vending gennem 90°. Fordelen med kun en enkelt opdeling af liggefladen i længderetningen består i, at ved en drejning gennem 90° er den tilbageblivende langsgående liggeflade vedblivende så DK 167205 B1 4 bred, at patienten bekvemt kan strække arme og ben. Med de kendte sengetyper kan patienten kun manuelt vendes om på siden, og skal herved støttes ved hjælp af puder for at 5 blive liggende i dette sideleje.When the bed setting options are fully utilized, it is possible to bring also physically severely impaired and weak patients to a desired auxiliary position. Eg. For example, a completely paralyzed patient can be turned through 90 ° by means of the longitudinally divided lying surface, which can be accomplished using only a single hand contact. To the extent that the patient is still able to move the arms or hands, the patient can perform this reversal himself through 90 °. The advantage of only a single longitudinal division of the lying surface is that, with a rotation through 90 °, the remaining longitudinal lying surface remains so wide that the patient can comfortably stretch arms and legs. With the known bed types, the patient can only be manually turned over on the side, and thus needs to be supported by pillows to stay in this side bed.

Ved den ovenfor beskrevne udformning af sengen, der er egnet til højre- og venstredrift, er det muligt at opnå, at også meget tunge patienter altid ligger midt i sengen.By the above-described design of the bed suitable for right and left operation, it is possible to achieve that even very heavy patients always lie in the middle of the bed.

Eftersom vendingsforløbet kan udføres jævnt ved hjælp af 10 en elektromotor og det samme tryk udøves på alle steder på patientens krop, udsættes patienten højst for en ringe smertebelastning.Since the reversal process can be performed evenly by means of an electric motor and the same pressure is exerted at all places on the patient's body, the patient is exposed to a small pain load at most.

Totalt lammede patienter kan opnå hjælp til sit kredsløb ved at sengen bringes i en lodret stilling i ca. 90° med 15 vandret. Herved er sengen normalt fremstillet af lakerede stålrør med liggefladen af fjedrende stålbånd. Imidlertid kan liggefladen også være udstyret med trælameller.Totally paralyzed patients can get help with their circuit by putting the bed in a vertical position for approx. 90 ° with 15 horizontal. Hereby, the bed is usually made of lacquered steel pipes with the lying surface of resilient steel bands. However, the reclining surface may also be equipped with wooden slats.

Hensigtsmæssigt er sengens fodende udformet bevægeligt på en sådan måde, at når liggefladen står i en vinkel på ca.Conveniently, the foot of the bed is designed to be movable in such a way that when the bed surface is at an angle of approx.

20 85°, kan fodenden tilpasses til gulvet. Dette gør det for forskellige patienter lettere at stige ind eller ud af sengen. En sådan seng kan også anvendes for patienter med forbrændinger, idet der i så fald anvendes rustfrit eller forkromet materiale. Sengens drivorganer kan drives elek-25 tromotorisk under anvendelse af spindelmotorer, eventuelt med batteridrift, eller også kan der anvendes hydrauliske eller pneumatiske drivorganer.20 85 °, the foot end can be adjusted to the floor. This makes it easier for different patients to get in or out of bed. Such a bed can also be used for patients with burns, in which case stainless or chromed material is used. The bed drive means can be electrically driven using spindle motors, possibly with battery operation, or hydraulic or pneumatic drive means can be used.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, der viser et udførelseseksempel 30 på en kombineret dreje- og ståseng ifølge opfindelsen, idet fig. 1 viser sengen med liggefladen i en øvre pleje- DK 167205 B1 5 position, set fra siden, fig. 2 viser liggefladen i den i fig. 1 viste seng med en opsvinget hoveddel, set fra siden, 5 fig. 3 viser den i fig. 1 viste seng med en liggef ladedel anbragt lodret, set fra siden, og fig. 4 viser sengen med en ensidigt hævet langsgående liggefladedel, set forfra.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawing, which shows an exemplary embodiment 30 of a combined swivel and bar bed according to the invention. 1 shows the bed with the bed surface in an upper care position, as seen from the side; FIG. 2 shows the lying surface of the embodiment of FIG. 1 is a side view of a raised body, FIG. 3 shows the one shown in FIG. 1 shows a side elevation of a loading portion vertically, and FIG. 4 is a front view of the bed with a unilateral raised longitudinal reclining section.

Fig. 1-4 viser en kombineret stå- og drejeseng 100, der er 10 anbragt på en bundramme 1,1a,Ib, lc, som kan køre på hjul ld, og hvori er anbragt en elektrisk spindelmotor 2, der er indrettet til at hæve og sænke sengerammen 5 ved hjælp af dennes lodrette bærestænger 5a, løftearme 3 og en forbindelsesstang 4. I sengerammen 5 er der anbragt en 15 ligge flader amme 6, der er fastgjort til en vippeaksel 7, der er fast anbragt på sengerammen 5.FIG. 1-4 show a combined standing and turning bed 100 arranged on a bottom frame 1,1a, lb, lc, which can be driven on wheels ld, and in which is arranged an electric spindle motor 2 adapted to raise and lowering the bed frame 5 by means of its vertical support rods 5a, lifting arms 3 and a connecting rod 4. In the bed frame 5 there is arranged a lying flat breast 6, which is attached to a rocking shaft 7 fixedly on the bed frame 5.

Inden for ligge fladerammen 6 er der anbragt en liggeflade 8, hvis hovedstykke 8c som vist i fig. 2 kan drejes om en i sengens tværretning forløbende vippeakse 9. Dreje- eller 20 vippebevægelsen udføres ved hjælp af en arm 10, der er svingeligt lejret i et i liggefladerammen 6 anbragt leje 11, og en hermed forbundet spindelmotor 12, idet den udragende ende af armen 10 bærer en rulle 22 til anlæg mod hovedstykket 8c.Within the surface frame 6 is a lying surface 8, whose headpiece 8c as shown in FIG. 2 can be pivoted about a rocking axis extending in the transverse direction of the bed 9. The turning or tilting movement is carried out by means of an arm 10 pivotally mounted in a bearing 11 arranged in the bed frame 6 and a spindle motor 12 associated therewith, the projecting end of the arm 10 carries a roller 22 for abutment against head piece 8c.

25 Fig. 3 viser sengen med tilnærmelsesvis lodret stillet liggef laderamme 6, idet bevægelsen til lodret stilling udføres ved drejning om vippeakslen 7 under påvirkning fra en spindelmotor 13 gennem en vinkelvægtstang 14,14a og en ledstang 16, hvoraf sidstnævnte danner forbindelse mellem 30 liggef laderammen 6 og vinkelvægtstangen 14,14a, der er drejeligt lejret på sengerammen 5 om en i sengens tværretning forløbende vippeaksel 15.FIG. 3 shows the bed with an approximately vertical reclining loading frame 6, the movement to the vertical position being effected by turning about the rocker shaft 7 under the influence of a spindle motor 13 through an angular bar 14,14a and a guide bar 16, the latter of which forms a connection between the reclining charging frame 6 and the angular bar 14,14a, pivotally mounted on the bed frame 5 about a tilting shaft 15 extending in the transverse direction of the bed.

Ved hjælp af denne forbindelses- og drivmekanisme 13,14, 14a,15,16 og forbindelses- og drivmekanismen 2,3,4,5a,5 er det muligt på samme tid at bevæge liggefladerammen 6 i 5 højderetningen og svinge den omkring vippeakslen 7. På denne måde er det under anvendelse af et egnet styrekredsløb for spindelmotorerne 2 og 13 muligt at lodretstille liggefladerammen 6 og dermed liggefladen 8 ud fra en hvilken som helst stilling af liggefladen. Eftersom for-10 bindelses- og drivmekanismerne 13,14,14a,15,16 og 2,3,4,5 er udformet og indrettet som beskrevet ovenfor og vist i fig. 1-4, er det ved passende styring muligt at undgå enhver indbyrdes bevægelseshindring mellem de enkelte dele, således at liggefladerammens bevægelsesforhold kan 15 forbedres i en sådan udstrækning, at det allerede i den nederste stilling af sengerammen 5 er muligt at udføre en vis skråstilling af liggefladerammen 6. Ved passende indretning af mikrokontakterne vil i så fald en videregående skråstilling af liggefladerammen 6 udløse en opadgående 20 bevægelse af sengerammen 5, således at denne automatisk hæves til den højde, som i hvert tilfælde er nødvendig til den pågældende skråstilling af liggefladerammen 6.By means of this connecting and driving mechanism 13,14, 14a, 15,16 and the connecting and driving mechanism 2,3,4,5a, 5 it is possible at the same time to move the lying surface frame 6 in the height direction and swing it around the rocker shaft 7 In this way, it is possible, using a suitable control circuit for the spindle motors 2 and 13, to vertically adjust the lying surface frame 6 and thus the lying surface 8 from any position of the lying surface. Since the connection and drive mechanisms 13,14,14a, 15,16 and 2,3,4,5 are designed and arranged as described above and shown in FIG. 1-4, it is possible to avoid, by appropriate control, any movement obstruction between the individual parts, so that the movement ratio of the bed frame can be improved to such an extent that it is already possible in the lower position of the bed frame 5 to carry out a certain inclination of In this case, a suitable inclination of the bed frame 6 will cause an upward movement of the bed frame 5, so that it is automatically raised to the height necessary in each case for the inclined position of the bed frame 6.

Til sengerammen 5 er der fastgjort en konsol 5b, hvorpå en støddæmper 35 er udskifteligt fastgjort. Den til 25 støddæmperen 35 hørende stempelstang 35a er forbundet med liggefladerammen 6 på en sådan måde, at dersom spindelmotoren 13 svigter eller der sker brud på vinkelvægtstangen 14,14a eller ledstangen 16, er det muligt at udføre en kraftigt dæmpet tilbagesvingning af liggefladerammen 6 til 30 vandret stilling. Herved opnås en betydelig forøgelse af sådanne senges driftssikkerhed.Attached to the bed frame 5 is a bracket 5b, on which a shock absorber 35 is interchangeably fixed. The piston rod 35a of the shock absorber 35 is connected to the bed frame 6 in such a way that if the spindle motor 13 fails or there is a break in the angular bar 14,14a or the link rod 16, it is possible to perform a strongly damped back swing of the bed frame 6 to 30 horizontal position. This results in a significant increase in the reliability of such beds.

En til liggefladerammen 6 hørende fodstøtte er på ydersiden forsynet med en hjulbærer 31 med et hjul 32, hvorved det er muligt at køre med liggefladerammen 6 i en 35 næsten lodret orientering, mens den samtidigt understøttes DK 167205 B1 7 på en sådan måde, at ikke alle kræfter overføres til sengerammen. Herved er det med sikkerhed undgået, at hele sengen 100 vælter, selv om bundrammen 1 og sengerammen 5 5 på ønsket måde er udformet som letvægtsdele.A footrest associated with the reclining frame 6 is provided on the outside with a wheel carrier 31 with a wheel 32, whereby it is possible to drive with the reclining frame 6 in an almost vertical orientation, while at the same time supporting DK 167205 B1 7 in such a way that not all forces are transferred to the bed frame. Hereby, it is certainly avoided that the entire bed 100 overturns, although the bottom frame 1 and the bed frame 5 5 are desirably designed as lightweight parts.

Som vist på tegningen kan sygesengen uden vanskeligheder udstyres med alt kendt tilbehør til sådanne senge, f.eks. med sidegitre, hoved- eller fodvægtsstænger og lignende. Herved er der fremskaffet en seng, der tilfredsstiller 10 alle krav fra fysisk stærkt hæmmede og svage patienter, især f.eks. patienter med dobbeltsidige lammelser. Med hensyn til betjeningsmulighederne, navnlig muligheden til igangsætning af et bevægelsesforløb, under hvilken ligge-fladen kontinuerligt bevæges fra den nederste vandrette 15 stilling til den lodrette stilling, er sengen tilpasset sådanne patienters behov.As shown in the drawing, the hospital bed can easily be equipped with all known accessories for such beds, e.g. with side grids, head or foot weights and the like. Thereby, a bed is provided which satisfies all the demands of physically severely impaired and weak patients, especially e.g. patients with bilateral paralysis. With regard to the operating possibilities, in particular the possibility of initiating a course of movement, during which the lying surface is continuously moved from the lower horizontal position to the vertical position, the bed is adapted to the needs of such patients.
