Abstract

The present invention relates to balanced suspension of an apparatus which is used in the lifting and/or transport of people. The person is normally suspended in the lifting sling in a fixed hook (3) and two hooks (4) on an arm (6) which is rotatably journalled via a shaft (5). The fixed hook (3) and the rotary arm (6) are disposed on a cassette (1) which supports a winder drum for a belt (2). The fixed hook (3) and the rotary shaft (5) of the arm (6) lie in an imaginary vertical plane (8) which bisects the belt (2) centrally. If the person in the lifting sling is suspended obliquely or changes position, the rotary arm (6) will assume an inclined position where the cassette (1) hangs straight. The person's point of gravity is automatically moved to the imaginary vertical plane (8).

I den visade utföringsformen innefattar anordningen en kassett 1, i vilken en motor och minst en upplindningstrumma (ej visade) är anord- nade. Pà upplindningstrumman lindas ett band 2, upp eller ut för att höja eller sänka kassettens läge i förhållande till en ej visad tak- transportör, lyftarm eller liknande. Bandet 2 gàr in via en öppning i kassettens hölje, vilken öppning styr bandets 2 läge i förhållande till upplindningstrumman. Bandet 2 uppbärs pâ en lyftarm, en vagn i en transportbana etc.In the embodiment shown, the device comprises a cassette 1, in which a motor and at least one winding drum (not shown) are arranged. On the winding drum, a belt 2 is wound up or out to raise or lower the position of the cassette in relation to a roof conveyor, lifting arm or similar, not shown. The belt 2 enters via an opening in the cassette housing, which opening controls the position of the belt 2 in relation to the winding drum. The belt 2 is supported on a lifting arm, a trolley in a transport path, etc.

Kassetten 1 uppbär en fast krok 3 och två krokar 4 anordnade pà en arm 6 som uppbärs vridbar pà en vridaxel 5. Den fasta kroken 3 och armen 6 med de tvâ krokarna 4 är anordnade pá motstáende sidor av kassetten 1.The cassette 1 carries a fixed hook 3 and two hooks 4 arranged on an arm 6 which is supported rotatably on a pivot axis 5. The fixed hook 3 and the arm 6 with the two hooks 4 are arranged on opposite sides of the cassette 1.

Krokarna 4 på armen 6 är anordnade vid armens bàda yttre ändar. Vridax- eln 5 är anordnad mitt pà armen 6 pà ett sådant sätt att armen 6 när den är obelastad lätt kan fås att inta ett horisontellt läge.The hooks 4 on the arm 6 are arranged at both outer ends of the arm. The rotary shaft 5 is arranged in the middle of the arm 6 in such a way that the arm 6, when unloaded, can easily be made to assume a horizontal position.

För att lyfta och/eller transportera en patient placeras patienten nor- malt pä en lyftsele, slinga eller liknande (ej visad). Lyftselen hängs sedan upp i den fasta kroken 3 och i krokarna 4 pä den vridbart lagrade armen 6. Normalt placeras patienten pá ett sådant sätt att den del av lyftselen som huvudsakligen uppbär överkroppen hängs upp i krokarna 4 6 pà den vridbara armen 6, medan den del som huvudsakligen uppbär benen hängs upp i den fasta kroken 3.To lift and / or transport a patient, the patient is normally placed on a sling, loop or similar (not shown). The sling is then hung in the fixed hook 3 and in the hooks 4 on the rotatably mounted arm 6. Normally the patient is placed in such a way that the part of the sling which mainly carries the upper body is hung in the hooks 46 on the rotatable arm 6, while the part which mainly supports the legs is hung up in the fixed hook 3.

Banden 2 har en sådan orientering att de bildar rät vinkel till ett tänkt vertikalt plan 8 som gár genom den fasta kroken 3 och vridaxeln 5 000000 lO l5 20 25 30 35 517 ass .- som uppbär armen 6 med de övriga krokarna 4. Det tänkta vertikala pla- net 8 gár mitt genom bandet eller banden 2 och delar det i tvâ lika stora delar.The straps 2 have such an orientation that they form a right angle to an imaginary vertical plane 8 which passes through the fixed hook 3 and the axis of rotation 5 000000 10 10 10 25 25 30 35 517 ass .- which supports the arm 6 with the other hooks 4. The imaginary the vertical plane 8 passes through the middle of the band or bands 2 and divides it into two equal parts.

Den i figur 7-9 visade utföringsformen skiljer sig frán utföringsformen 1-6 i princip endast genom att den vridbara armen 7 som uppbär krokar 4 vid sina yttre ändar är bägformad. Bàgformen pà armen 7 har en sådan riktning att armens 7 krokar 4 kommer närmare mitten av kassetten 1 än vid den tidigare utföringsformen. Dessutom antyds i figur 7-9 möjlighe- ten att tvà band med tillhörande upplindningstrummor i vissa utförings- former är anordnade i kassetten 1.The embodiment shown in Figures 7-9 differs from the embodiment 1-6 in principle only in that the rotatable arm 7 which supports hooks 4 at its outer ends is cup-shaped. The arcuate shape of the arm 7 has such a direction that the hooks 4 of the arm 7 come closer to the center of the cassette 1 than in the previous embodiment. In addition, Figures 7-9 indicate the possibility that two belts with associated winding drums in certain embodiments are arranged in the cassette 1.

Genom armens 7 bàgform hamnar patientens tyngdpunkt normalt i det när- maste rakt under banden 2. Detta gör att patienten snabbt förs till ett stabilt läge.Through the arcuate shape of the arm 7, the patient's center of gravity normally ends up almost directly below the straps 2. This means that the patient is quickly moved to a stable position.

I andra utföringsformer (ej visade) ersätts den fasta kroken 3 av en vridbart lagrad arm, varvid det således är en vridbart arm på två mot- stående sidor hos kassetten.In other embodiments (not shown) the fixed hook 3 is replaced by a rotatably mounted arm, thus being a rotatable arm on two opposite sides of the cassette.

I stället för krokar kan tappar, karbinhakar eller andra lämpliga organ användas.Instead of hooks, pins, carabiners or other suitable means can be used.

Kassetten 1 kan ersättas av en annan lämplig anordning för att uppbära motor och upplindningstrummor.The cassette 1 can be replaced by another suitable device for supporting the motor and winding drums.

För att få ett stabilt jämviktsläge bör dessutom upplindningstrummans centrum ligga pá en högre nivá än armens 6, 7 vridaxel 5.In addition, in order to obtain a stable equilibrium position, the center of the winding drum should be at a higher level than the axis of rotation 5 of the arm 6, 7.

När en patient är upphängd i en lyftsele i krokarna 3, 4 enligt ovan gör den vridbara armen 6, 7 att patientens tyngdpunkt automatiskt förs till det vertikala planet 8, som går genom vridaxeln 5, bandet 2 och u den fasta kroken 3. Kassetten 1 kommer därigenom att alltid hänga med upplindningstrummans axel i horisontalplanet varför man inte riskerar sned inmatning av bandet 2. Den automatiska balanseringen sker tack vare att vridarmens 6 vridaxel 5 och den fasta kroken 3 är anordnade i samma vertikala plan 8 som mitten av bandet 2 i vilket kassetten 1 är Ovinvd uounøv msn» 11:e: lO l5 517 sas .- upphängd. Vid balanserad upphängning sammanfaller det vertikala planet normalt med patientens medialplan. Även om patienten ändrar läge under lyftrörelsen eller transporten änd- rar vridarmen 6 snabbt läge och ser till att patientens tyngdpunkt förs till nämnda vertikala plan 8.When a patient is suspended in a sling in the hooks 3, 4 as above, the rotatable arm 6, 7 causes the patient's center of gravity to be automatically moved to the vertical plane 8, which passes through the axis of rotation 5, the strap 2 and the fixed hook 3. The cassette 1 will thereby always hang with the axis of the winding drum in the horizontal plane, so there is no risk of skewed feeding of the belt 2. The automatic balancing takes place thanks to the pivot shaft 5 and the fixed hook 3 being arranged in the same vertical plane 8 as the center of the belt 2 in which cassette 1 is Ovinvd uounøv msn »11th: lO l5 517 sas .- suspended. With balanced suspension, the vertical plane normally coincides with the patient's medial plane. Even if the patient changes position during the lifting movement or transport, the rotary arm 6 quickly changes position and ensures that the patient's center of gravity is moved to said vertical plane 8.

Upphängningen enligt föreliggande uppfinning blir mycket stabil genom att den hela tiden strävar efter och får möjlighet att inta ett jäm- viktsläge där kassetten 1 hänger rakt. Detta innebär att bandet 2 kom- mer att matas in pá ett säkert sätt utan tendenser till sned inmatning. Även om patienten gör kraftiga rörelser kommer anordningen att snabbt inta ett jämviktsläge.The suspension according to the present invention becomes very stable in that it constantly strives for and is given the opportunity to assume an equilibrium position where the cassette 1 hangs straight. This means that belt 2 will be fed in in a safe manner without tendencies to skew feed. Even if the patient makes strong movements, the device will quickly assume an equilibrium position.
