Den foreliggende opfindelse angår en invalidestol med en grundramme, som bærer et sæde, et ryglæn samt to armlæn hvor sædet er opdelt i to i forhold til hinanden bevægelige dele, hvoraf den ene del udgøres af en saddelformet siddedel, som ved hjælp af et ledsystem og en drivmekanisme kan hæves, respektiv sænkes mellem en normal siddestilling og en øvre stilling for at løfte en siddende person op i oprejst stilling, respektiv for at hjælpe en stående person ned i siddestilling.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an invalid chair having a base frame carrying a seat, a backrest and two armrests wherein the seat is divided into two mutually movable parts, one part of which is formed by a saddle-shaped seat part which, by means of a linkage system and a driving mechanism can be raised or lowered, respectively, between a normal sitting position and an upper position to lift a seated person into an upright position, respectively to assist a standing person in a sitting position.
Stole beregnet til at gøre det lettere for en person at rejse sig fra stolen er kendt fra US-patentskrift nr. 1.288.216 og 3.138.402, GB-patentskrift nr. 998.676 og SE-patentskrift nr. 380.425. Et fælles træk ved disse tidligere kendte stole er at sædet eller en del af sædet kan bevæges ved hjælp af en drivmekanisme fra en normal stilling til en øvre stilling for at assistere personen i at rejse sig fra stolen. Imidlertid vil de kendte stole hæve personen til en stilling hvor han kun vil have partiel assistance fra stolen når han forlader stolen for at opnå den endelige stilling, stående på sine fødder.Chairs intended to make it easier for a person to rise from the chair are known from US Patent Nos. 1,288,216 and 3,138,402, GB Patent Nos. 998,676 and SE Patent Nos. 380,425. A common feature of these prior art chairs is that the seat or part of the seat can be moved by a drive mechanism from a normal position to an upper position to assist the person in getting up from the chair. However, the known chairs will raise the person to a position where he will only have partial assistance from the chair when he leaves the chair to obtain the final position, standing on his feet.
Det er formålet med den foreliggende opfindelse at tilvejebringe en invalidestol, som vil sikre invaliden en forbedret sikker assistance når han rejser sig fra en siddende stilling eller når han sætter sig ned.It is the object of the present invention to provide a disability chair which will provide the disabled with an improved safe assistance when getting up from a sitting position or sitting down.
Dette opnås ved hjælp af en stol af den ovenfor nævnte type, som ifølge opfindelsen er ejendommelig ved at ryglænet, armlænene og den saddelformede siddedel er stift forbundne med hverandre som en enhed, at sædets anden del udgøres af en den saddel-formede siddedel delvis omsluttende U-formet siddedel eller benunderstøttende del, der med sin lukkede ende ligger foran den saddelformede siddedel og som ved forkanten ved hjælp af en tværgående ledaksel er drejeligt forbundet med grundrammen, medens den ved sin bagudvendende dele er ledbart forbundet med den bageste del af den saddelformede siddedel eller med dele, der er stift forbundne med ryglænets underkant, således at når man aktiverer drivmekanismen for hævning af den saddelformede del, så vil den benunderstøttende del blive svunget opad med sin bageste del, mens den saddelformede del vil blive løftet i forhold til frontdelen af den benunderstøttende del.This is achieved by means of a chair of the above-mentioned type, which according to the invention is characterized in that the backrest, the armrests and the saddle-shaped seat part are rigidly connected to each other as a unit, that the second part of the seat is constituted by a saddle-shaped seat part. U-shaped seat part or leg support part, which with its closed end is in front of the saddle-shaped seat part and which is rotatably connected to the base frame by means of a transverse articulated shaft, while at its rearward-facing part it is pivotally connected to the rear part of the saddle-shaped part. seat part or with parts rigidly connected to the lower edge of the backrest, so that when activating the drive mechanism for raising the saddle-shaped part, the leg-supporting part will be pivoted upwards with its rear part, while the saddle-shaped part will be lifted relative to the front part of the leg support portion.
Stolen ifølge opfindelsen kan med fordel være udformet således at der til et nedre tværstykke på grundrammen ledbart er 2 146151 tilsluttet to forbindelsesstænger, og at der ved den bageste del af den saddelformede siddedel ledbart er tilsluttet to forbindelsesstænger som er ledbart forbundne med de førstnævnte forbindelsesstænger, hvilke forbindelsesstænger sammen med den U-formede siddedel danner et firehjørnet, i det væsentlige parallellogram-formet ledsystem. En sådan udformning giver stolen en særligt enkel opbygning idet den U-formede siddedel selv kommer til at deltage i dannelsen af det i det væsentlige parallellogramformede ledsystem.The chair according to the invention may advantageously be designed such that two connecting rods are pivotally connected to a lower cross-section of the basic frame and that at the rear of the saddle-shaped seat part are pivotally connected two connecting rods which are pivotally connected to the former connecting rods, which connecting rods together with the U-shaped seat part form a four-cornered, essentially parallelogram-shaped joint system. Such a design gives the chair a particularly simple structure as the U-shaped seat part itself participates in the formation of the essentially parallelogram-shaped joint system.
Ifølge en fordelagtig udførelsesform er stolen ifølge opfindelsen udformet således at der ved oversiden af en tværgående skinne på grundrammen, som danner det forreste led for den U-formede siddedel, ledbart er tilsluttet to forbindelsesstænger, og at der ved den tværgående skinnes underside ledbart er tilsluttet mindst en forbindelsesstang, hvilken eller hvilke forbindelsesstænger med deres andre ender er ledbart forbundne med et ved ryglænets nedre kant indrettet tværrør henholdsvis med til rygstødets nedre ende stift forbundne dele til dannelse af et i det væsentlige parallellogramlignende ledsystem. Herved opnår man at ledsystemet koncentreres til det område, der ligger tæt under sædet, således at ledsystemet om ønsket let kan skjules ved hjælp af dækplader ved sædets sider.According to an advantageous embodiment, the chair according to the invention is designed such that at the upper side of a transverse rail on the base frame which forms the front link of the U-shaped seat part, two connecting rods are pivotally connected and that at the underside of the transverse rail is pivotally connected at least one connecting rod, which connecting rod (s) at their other ends is pivotally connected to a transverse tube arranged at the lower edge of the backrest and to portions connected to the lower end of the backrest, respectively, to form a substantially parallelogram-like joint system. In this way, the joint system is concentrated to the area which is close to the seat, so that the joint system can be easily concealed, if desired, by cover plates at the sides of the seat.
Ifølge yderligere en fordelagtig udførelsesform kan stolen ifølge opfindelsen være udformet således, at tværskinnen er fastgjort ved de forreste ender af to bæreskinner, som er forskydeligt lejrede i to langsgående i det væsentlige vandrette styreskinner som er fæstnede ved grundrammen, og at den U-formede siddedel ved hjælp af to forbindelsesstænger er forbundet med disse styreskinner. Herved opnår man at det ved indbyrdes forskydning af bæreskinnerne og styreskinnerne er muligt at forskyde den saddelformede siddedel ved hævning og sænkning på en sådan måde at tyngdepunktet for den på siddedelen siddende person i det væsentlige vil forblive i det samme lodrette plan, således at man undgår risikoen for at stolen vælter.According to a further advantageous embodiment, the chair according to the invention may be designed such that the transverse rail is secured to the front ends of two support rails which are slidably mounted in two longitudinal substantially horizontal guide rails attached to the base frame and that the U-shaped seat part two connecting rods are connected to these guide rails. Hereby it is achieved that by mutually displacing the support rails and guide rails it is possible to displace the saddle-shaped seat part by raising and lowering in such a way that the center of gravity of the person sitting on the seat part will remain essentially in the same vertical plane, so as to avoid the risk of the chair falling over.
Drivmekanismen er fortrinsvis en reversibel elektrisk motor der driver en skruedonkraft.The drive mechanism is preferably a reversible electric motor that drives a screwdriver.
Når man hæver sædet vil den saddelformede siddedel efterhånden blive opløftet i forhold til den benunderstøttende siddedel, 146151 3 således at invaliden vil blive sat på den saddelformede del med sine ben langs den benunderstøttende del som svinges til en skråt-stillet stilling således at benene efterhånden strækkes ud. Under alle bevægelser opad eller nedad vil personen hele tiden være i stand til at have støtte fra ryglænet og armlænene og den saddelformede del, hvilket giver personen den ønskede sikkerhedsfølelse. Stolen kan let indstilles til den aktuelle størrelse af personen, således at personen, når den saddelformede del er i sin maximale øvre stilling, vil blive understøttet af den saddelformede del i en i det væsentlige stående stilling med fødderne på gulvet.When raising the seat, the saddle-shaped seat part will gradually be raised relative to the leg-supporting seat part, so that the disability will be placed on the saddle-shaped part with its legs along the leg-supporting part which is pivoted to an inclined position so that the legs are eventually stretched. out. During any upward or downward movement, the person will always be able to have support from the backrest and armrests and the saddle-shaped part, giving the person the desired feeling of safety. The chair can be easily adjusted to the actual size of the person so that when the saddle-shaped part is in its maximum upper position, the person will be supported by the saddle-shaped part in a substantially upright position with the feet on the floor.
Dette betyder at personen kan holde sine hænder på armlænene og med en lille bevægelse fremad forlade den saddelformede siddedel i en praktisk talt opret, stående stilling.This means that the person can keep his hands on his armrests and move slightly forward with the saddle-shaped seat part in a practically upright, upright position.
En prototype af stolen ifølge opfindelsen og henholdsvis to foretrukne udførelsesformer vises som eksempler i forbindelse med tegningen, hvor fig. 1 er et skematisk perspektivbillede af en prototype-stol i en normal stilling, fig. 2 er et perspektivbillede af prototypestolen i den øvre stilling, fig. 3 er et skematisk perspektivbillede af en anden udførelsesform for stolen i en normal stilling, fig. 4 er et perspektivbillede af stolen ifølge fig. 3 i den øvre stilling, fig. 5 er et skematisk tværsnit gennem stolen vist med fuldt optrukne linier for den normale stilling som vist på fig. 3 og med streg-prik-linier for den øvre stilling som vist på fig. 4, fig. 6 er et delvist opskåret snit gennem stolen ifølge fig. 3, og fig. 7 er et skematisk tværsnit af en tredie udførelsesform vist i en normal stilling og med streg-prik-linier i en øvre stilling.A prototype of the chair according to the invention and two preferred embodiments, respectively, are shown by way of example with reference to the drawing, in which fig. 1 is a schematic perspective view of a prototype chair in a normal position; FIG. 2 is a perspective view of the prototype chair in the upper position; FIG. Figure 3 is a schematic perspective view of another embodiment of the chair in a normal position; 4 is a perspective view of the chair of FIG. 3 in the upper position; FIG. 5 is a schematic cross-section through the chair shown in solid lines for the normal position as shown in FIG. 3 and with dash-dotted lines for the upper position as shown in FIG. 4, FIG. 6 is a partially cut section through the chair of FIG. 3, and FIG. 7 is a schematic cross section of a third embodiment shown in a normal position and with dash-dotted lines in an upper position.
Prototypestolen på fig. 1 og 2 har en grundramme 10 som bærer det opdelte sæde, som omfatter en saddelformet siddedel 11 og en benunderstøttende siddedel 12, som omgiver den saddelformede del langs dennes sidedele og frontdel til dannelse af en i det væsentlige U-formet del.The prototype chair of FIG. 1 and 2 have a base frame 10 supporting the divided seat which comprises a saddle-shaped seat part 11 and a leg-supporting seat part 12 which surrounds the saddle-shaped part along its side parts and front part to form a substantially U-shaped part.
Ryglænet 13 har to armlæn 14, 15. Den saddelformede del 11 er stift fastgjort til ryglænet.The backrest 13 has two armrests 14, 15. The saddle-shaped part 11 is rigidly attached to the backrest.
4 1461514 146151
Den benunderstøttende del 12 er ved sin forkant hængselforbundet med grundrammen 10 ved hjælp af et hængsel 16.The leg support portion 12 is hingedly connected to the base frame 10 by its hinge 16 at its leading edge.
Ved den benunderstøttende dels 12 bagender er den hæng-selforbundet ved hjælp af hængsler 17 til ryglænet 13 eller til en del 11a som er fastgjort til ryglænet.At the rear of the leg support portion 12, it is hingedly connected by hinges 17 to the backrest 13 or to a portion 11a attached to the backrest.
Grundrammen 10 har et tværstykke 10a der understøtter en reversibel elektrisk motor 18 som driver en konventionel skruedonkraft 19, idet motoren er ledbart monteret på tværstykket 10a og ledforbundet i sin øvre ende med den saddelformede dels 11 underside.The base frame 10 has a crosspiece 10a which supports a reversible electric motor 18 which drives a conventional screwdriver 19, the motor being pivotally mounted on the crosspiece 10a and articulated at its upper end with the underside of the saddle portion 11.
For at fastholde en i det væsentlig vandret stilling af den saddelformede del 11 når den hæves fra sin normale stilling som vist på fig. 1 til den øvre stilling på fig. 2 er der et ledsystem som omfatter følgende elementer. Et par forbindelsesstænger 20, 21 strækker sig fra ryglænet og er i deres nedre ender med drejeled 22, 23 forbundet med forbindelsesstænger 24, 25, som i deres forender er forbundet med hængsler 26, 27 til tværstykket 10a. I overensstemmelse hermed vil ledsystemet fastholde den saddelformede del i en i det væsentlige vandret stilling. Skulle det imidlertid ønskes at have den saddelformede del skrånende opad eller nedad i dens øvre stilling er det let at opnå dette ved indstilling af forbindelsesstængernes længder i ledsystemet.To maintain a substantially horizontal position of the saddle-shaped portion 11 when raised from its normal position as shown in FIG. 1 to the upper position of FIG. 2 there is a joint system comprising the following elements. A pair of connecting rods 20, 21 extend from the backrest and are connected at their lower ends by swivel joints 22, 23 to connecting rods 24, 25 which at their ends are connected by hinges 26, 27 to the cross piece 10a. Accordingly, the linkage system will retain the saddle-shaped portion in a substantially horizontal position. However, if it is desired to have the saddle-shaped part sloped upwards or downwards in its upper position, this is easily achieved by adjusting the lengths of the connecting rods in the joint system.
Den elektriske motor reguleres ved hjælp af en kontakt monteret på det ene af armlænene.The electric motor is controlled by means of a switch mounted on one of the armrests.
Det vil forstås fra fig. 2 at personen vil sidde på den saddelformede del 11 med sine ben anbragt på siderne af den saddelformede del og rettet i det væsentlige lodret og i det væsentlige udstrakt og hvilende med fødderne på gulvet. Personen kan have sine hænder på armlænene 14, 15 og kan yderligere have støtte af ryglænet. Ved at læne sig fremad og skubbe mod armlænene vil personen på sikker måde kunne indtage en stående stilling fri fra stolen. Man går frem på den omvendte måde når man sætter sig ned.It will be understood from FIG. 2, the person will sit on the saddle-shaped part 11 with his legs positioned on the sides of the saddle-shaped part and directed substantially vertically and substantially extended and resting with the feet on the floor. The person may have his hands on the armrests 14, 15 and may further have support of the backrest. By leaning forward and pushing against the armrests, the person can safely occupy a standing position free of the chair. You go the opposite way when you sit down.
På fig. 3-6 vises en foretrukket udførelsesform som har en grundramme som omfatter to T-formede ben 28, 29 med hjul 30.In FIG. 3-6 shows a preferred embodiment having a base frame comprising two T-shaped legs 28, 29 with wheels 30.
Den lodrette del af benene er fortrinsvis teleskopisk regulerbare for at gøre det muligt at stolen indstilles efter den pågældende persons benlængde.The vertical portion of the legs is preferably telescopically adjustable to allow the chair to be adjusted according to the person's leg length.
Ryglænet 13 har to armlæn 14, 15 og er i sin nedre ende fastgjort til et tværrør 31 til hvilken der er fastgjort en kon- 146151 5 solarm 32 (fig. 5 og 6) som støtter sædets saddelformede del 11b. Sædets benunderstøttende del 12a og den saddelformede del 11b er svagt modificeret i forhold til den benunderstøttende del 12 og den saddelformede del 11 på fig. 1.The backrest 13 has two armrests 14, 15 and is attached at its lower end to a transverse tube 31 to which is attached a tapered arm 32 (Figs. 5 and 6) which supports the saddle-shaped portion 11b. The leg support portion 12a of the seat and the saddle-shaped portion 11b are slightly modified relative to the leg-supported portion 12 and the saddle-shaped portion 11 of FIG. First
Benene 28, 29 har i deres øvre ender en konsolarm 31 fastgjort til en tværskinne 52.The legs 28, 29 have at their upper ends a bracket arm 31 attached to a cross rail 52.
Ved hver ende af skinnen 52 er der et par ører 33 til at bære en tap 33a til drejelig forbindelse til en øvre forbindelsesstang 34 med sin bagende drejeligt forbundet med en tap 35a med et par ører 35 på røret 31. Længden af den øvre forbindelsesstang 34 er indstillelig.At each end of the rail 52 there are a pair of ears 33 for carrying a pivot 33a for pivotal connection to an upper connecting rod 34 with its rear pivotally connected to a pin 35a with a pair of ears 35 on the tube 31. The length of the upper connecting rod 34 is adjustable.
Idet væsentlige i midten af tværskinnen 52 er der et nedre par ører 36 til at bære en tap 36a til drejelig montering af elektromotoren 18, dens gearkasse 18a og donkraften 19 med sin øvre ende drejeligt forbundet med en tap 37a båret af et par ører 37 på røret 31.Essentially in the center of the transverse rail 52 there is a lower pair of ears 36 for carrying a pin 36a for pivotally mounting the electric motor 18, its gearbox 18a and the jack 19 with its upper end pivotally connected to a pin 37a worn by a pair of ears 37 on the the tube 31.
En nedre forbindelsesstang 38 har sin forende forbundet med en tap 39a båret af et par nedre ører 39 på forbjælken 32, og forbundet i sin bagende med en tap 40a til et par vægtarme 40.A lower connecting rod 38 has its front end connected to a pin 39a supported by a pair of lower ears 39 on the front bar 32, and connected at its rear end with a pin 40a to a pair of arms 40.
Ledsystemet som har sine hængselpunkter ved de fire tappe 33a, 39a og 40a kan danne et parallellogram eller kan ved indstilling af forbindelsesstængernes længder afvige mere eller mindre fra et parallellogram således at den saddelformede del 11b kan være i det væsentlige vandret eller kan skråne nedad i ønsket omfang i forhold til den på fig. 5 viste stilling.The linkage system having its hinge points at the four pins 33a, 39a and 40a may form a parallelogram or, when adjusting the lengths of the connecting rods, may deviate more or less from a parallelogram such that the saddle-shaped portion 11b may be substantially horizontal or inclined downwardly as desired. size in relation to that of FIG. 5.
Funktionen af den stol der er vist på fig. 5 og 6 er den samme som på fig. 1 og 2, men hovedfordelen er at ledsystemet er koncentreret i et rum der ligger tæt under sædet således at det om ønsket let kan skjules ved hjælp af en dækplade på sædets sider.The function of the chair shown in FIG. 5 and 6 are the same as in FIG. 1 and 2, but the main advantage is that the joint system is concentrated in a space close to the seat so that if desired it can be easily concealed by means of a cover plate on the sides of the seat.
Selv om det ikke er vist kan der være et par kompressionsfjedre eller et par gasopererede fjederelementer monteret til at assistere skruedonkraften 19, således at den elektriske motor kan have en forholdsvis lille kraft til at bevæge ledsystemet.Although not shown, there may be a pair of compression springs or a pair of gas operated spring elements mounted to assist the screw power 19 so that the electric motor may have a relatively small force to move the joint system.
Som det vil ses af fig. 7 og 5 har forkanten 41 på den saddelformede del 11b den samme stilling i den normale stilling, mens i den øvre stilling forkanten 41 på fig. 5 er blevet bevæget fremad i en afstand svarende til ca. længden af den saddelformede 6 146151 del lib.. Dette giver en formindskelse i stabiliteten, mod hvilken der kunne kompenseres ved at udstrække rammens basis, således at. forhjulene 30 vil være anbragt et godt stykke foran stolen, hvilket igen ville kræve mere fri plads på gulvet til at dreje stolen omkring.As will be seen from FIG. 7 and 5, the leading edge 41 of the saddle-shaped part 11b has the same position in the normal position, while in the upper position the leading edge 41 of FIG. 5 has been moved forward at a distance corresponding to approx. the length of the saddle-shaped 6 146151 part lib. This provides a decrease in stability against which it could be compensated by extending the base of the frame so that. the front wheels 30 will be positioned well ahead of the chair, which in turn would require more free space on the floor to turn the chair around.
I modsætning hertil vil forkanten 41 på fig. 7 blive bevæget langs en i det væsentlige lodret vej, hvilket betyder at tyngdepunktets stilling for personen vil forblive praktisk talt konstant i dens stilling mellem forhjulene og baghjulene 30 i blindrammen. Dette opnås simpelt hen ved at der er to bæreskinner 42a der er giideligt monteret hver i en styreskinne 42, som er fastgjorte og understøttet af de respektive ben 28 og 29, idet forenden af hver bæreskinne er fastgjort til forbjælken 32 således at denne kan bevæges fra sin foran liggende stilling som vist på fig. 7 til sin tilbagetrukne stilling som vist med streg-prik-linier på fig. 7. Denne bevægelse opnås ved hjælp af et forbindelsesstykke 43 for hver styreskinne 42a, idet forbindelsesstykket er ledforbundet med et par ører 43 på bagenden af styreskinnen og et par ører 44 på undersiden af den benunderstøttende del 12a. Når bagenden af delen 12a svinges op ved drejning ved 33a vil forbindelsesstykkerne 43 svinges til den stilling der er vist med streg-prik-linier, hvorved forenden af den benunderstøttende del og derved også tværskinnen 52 presses til at bevæge sig bagud til de stillinger der er vist med streg-prik-linier.In contrast, the leading edge 41 of FIG. 7 is moved along a substantially vertical path, which means that the center of gravity of the person will remain practically constant in its position between the front wheels and the rear wheels 30 in the blind frame. This is accomplished simply by having two support rails 42a affixed each in a guide rail 42 which is secured and supported by the respective legs 28 and 29, the front end of each support rail being secured to the front bar 32 so that it can be moved from its forward position as shown in FIG. 7 to its retracted position as shown by dash-dotted lines in FIG. 7. This movement is accomplished by means of a connecting piece 43 for each guide rail 42a, the connecting piece being articulated with a pair of ears 43 on the rear of the guide rail and a pair of ears 44 on the underside of the leg support portion 12a. As the rear end of the portion 12a is pivoted by rotation at 33a, the connecting pieces 43 will be pivoted to the position shown by dash-dotted lines, thereby pressing the front end of the leg support portion and thereby also the transverse rail 52 to move backward to the positions that are shown with dash-dotted lines.
