Description

Anordning for att fa ett armstad vid en rullstol att bibehalla konstant riktningsvinkel samt rullstol Foreliggande uppf inning avser en anordning for en rull- stol omfattande en bottenram, ett sate, som kan lutas i olika vinklar relativt bottenramen, ett ryggstod, som kan lutas i olika vinklar relativt bade bottenramen och satet, och ett armelement med ett armstad, dar armelementet ãr vridbart anordnat till ryggstodet via en farsta vridningspunkt. The present invention relates to a device for a wheelchair comprising a bottom frame, a seat which can be tilted at different angles relative to the bottom frame, a backrest which can be tilted at different angles. angles relative to both the bottom frame and the seat, and an arm element with an armrest, where the arm element is rotatably arranged to the backrest via a first pivot point.

I WO 2009/058077 visas en stol med ett sate, ett ryggstod och ett armstod, dar stolen kan inta ett ligglage, ett sittlage och ett stalage. ArmstOdet ar vridbart anordnat till ryggstodet via en vridbar led och dar den vridbara leden, i sin tur, är forskjutbar i ryggstodets langdriktning via ett skensystem pa ryggstodet. Ett tamligen komplicerat lanksystem, som innefattar ovan namnda skensystem, tillgodoser att armstadet är hori- sontellt vid stolens samtliga lagen. WO 2009/058077 shows a chair with a seat, a backrest and an armrest, where the chair can accommodate a reclining position, a sitting position and a standing position. The armrest is rotatably mounted to the backrest via a rotatable joint and where the rotatable joint, in turn, is displaceable in the longitudinal direction of the backrest via a rail system on the backrest. A rather complicated lance system, which includes the above-mentioned rail system, ensures that the armrest is horizontal at all the layers of the chair.

En nackdel med denna stol är att den blir ganska komplex och tung, eftersom den kraver att ett skensystem al- anordnat i ryggstodet. Dessutom am- det inte bra fOr anvandaren att armstodet flyttas relativt ryggstodet, eftersom detta kan ge upphov till friktion mellan underarmar och armstod och/eller mellan rygg och ryggstad. Vidare är ryggstodet direkt vridbart via en lank till sittdelen, vilket ger en rOrelse hos ryggst(5- det, som inte foljer kroppens naturliga rorelsemonster vid exempelvis en resning fran ett liggande lage till ett sittande lage. A disadvantage of this chair is that it becomes quite complex and heavy, as it requires a rail system to be arranged in the backrest. In addition, it is not good for the user that the armrest is moved relative to the backrest, as this can give rise to friction between the forearms and armrest and / or between the back and the backrest. Furthermore, the backrest is directly rotatable via a link to the seat part, which gives a movement of the backrest (5), which does not follow the body's natural movement pattern during, for example, a rise from a lying position to a sitting position.

Andamalet med fOreliggande uppf inning dr att frambringa en anordning fOr en rullstol, dar anordningen innefat- tar ett ryggstod och ett armelement, som dr vridbart anordnat pa ryggstodet och dar ett armstod hos 1 armelementet bibehdller en konstant riktningsvinkel, som dr oberoende av ryggstodets och satets respektive lutningsvinklar. Anordningen enligt uppfinningen innefattar ett armldnksystem, som upphaver de nackdelar som beskrivs med den kanda tekniken ovan. The object of the present invention is to provide a device for a wheelchair, where the device comprises a backrest and an arm element, which is rotatably arranged on the backrest and where an armrest of the arm element maintains a constant directional angle, which is independent of the backrest and seat respective angles of inclination. The device according to the invention comprises an armrest system which has the disadvantages described with the prior art above.

Pa armstodet 13 har armelementet 4 en ovre, fri, forsta &ride 15 och pa riktarmen 14 har armelementet 4 en nedre, ledad, andra dnde 16. Armelementet 4 har ett V-format, spetsigt mittenparti 17, ddr armstodet 13 gar samman med riktarmen 14. Det spetsiga mittenpartiet 17 hos armelementet 4 dr vridbart anordnat till ryggstodet 3 via en forsta vridningspunkt A. Vid anvandning av anordningen ar armstodet 13 anordnat for att vila underarmarna hos en anvandare av anordningen. Riktarmen 14 ãr anordnad f6r att tillgodose att armstodet 13 hela tiden har en horisontell orienteringsriktning vid anv&ndning. Den nedre, andra dnden 16 är vridbart anordnad till den ovre ldnkarmens 6 ovre, forsta ande 7 via en andra vridningspunkt B. The armrest system 5 comprises an upper arm arm 6 with an upper, first end 7 and a lower, second end 8; a lower long arm 9 having an upper, first end 10 and a lower, second end 11, and a displaceable, telescopic sliding body 12 having an upper, first end 22 and a lower, second end 23, which sliding body 12 is arranged to move along the upper link arm 6 and the lower link arm 9. The V-shaped arm element 4 comprises an armrest 13 and a guide arm 14. On the armrest 13 the arm element 4 has an upper, free, front & ride 15 and on the guide arm 14 the arm element 4 has a lower, articulated, second end 16. The arm element 4 has a V-shaped, pointed middle portion 17, where the armrest 13 joins the guide arm 14.

Den nedre ldnkarmens 9 andra dnde 11 är vridbart anordnad till bottenramen 1 via en fjdrde vridningspunkt D, ddr den fj&rde vridningspunkten D ár beldgen vid bottenramens 1 frdmre &ride 18. The second end 11 of the lower support frame 9 is rotatably arranged to the bottom frame 1 via a fourth pivot point D, where the fourth pivot point D is the bellows at the front frame 18 of the bottom frame 1.

Satets 2 bakre &ride 21 dr ledbart forbunden med glidkrop- pens 12 forsta dnde 22 via en femte vridningspunkt E. Seat 2 rear & ride 21 door articulated to the front end 22 of the slider 12 via a fifth pivot point E.

I figur 1 visas anordningen i ett liggldge, ddr sdtet 2, ryggstodet 3 och armstodet 13 samtliga ãr i ett horison- tellt ldge. Glidkroppens 12 forsta ande 22 dr dá beldgen nara den tredje vridningspunkten C, som vridbart forbinder den ovre lamkarmen 6 med den nedre ldnkarmen 9. Figure 1 shows the device in a reclining position, where the seat 2, the backrest 3 and the armrest 13 are all in a horizontal position. The first end 22 of the sliding body 12 then moves the bellows to the third pivot point C, which pivotally connects the upper lamb frame 6 to the lower lead frame 9.

I figur 2 visas anordningen i ett sittlage, dar satet 2 och armstodet 13 bada är horisontella och dar ryggstadet 3 ar i ett uppratt, vertikalt lage. Glidkroppens 12 4 forsta Aside 22 ar dá fortfarande belagen nara den tredje vridningspunkten C. Vid uppresningen av ryggstodet 3 vrids ryggst6det 3 i en fOrsta vridningsriktning, samtidigt som armelementet 4 vrids kring den forsta vridnings- punkten A i en andra vridningsriktning, som ãr motsatt den forsta vridningsriktningen. Armelements 4 vridning beror pa att den ovre lankarmen 6 ãr kopplad till armelementets 4 riktarm 14. Ryggstodets 3 uppresning medf6r att den Ovre lankarmen 6 vrids i den forsta vridningsrikt- ningen kring den tredje vridningspunkten C. Detta gar att armstodets 13 horisontella orienteringsriktning bibehalles under hela lyftrorelsen av ryggstodet 3. Figure 2 shows the device in a sitting position, where the seat 2 and the armrest 13 are both horizontal and where the backrest 3 is in an upright, vertical position. The first Aside 22 of the sliding body 12 4 is then still coated near the third pivot point C. When the backrest 3 is raised, the backrest 3 is rotated in a first direction of rotation, while the arm element 4 is rotated about the first pivot point A in a second direction of rotation, which is opposite to first direction of rotation. The rotation of the arm element 4 is due to the fact that the upper longitudinal arm 6 is coupled to the direct arm 14 of the arm element 4. The erection of the backrest 3 means that the upper longitudinal arm 6 is rotated in the first direction of rotation around the third point of rotation C. This is maintained. the lifting motion of the backrest 3.

I figur 3 visas anordningen i ett stalage, dar armstodet 13 ar horisontellt och dar bade satet 2 och ryggstodet 3 ar vertikala. RyggstOdet 3 ar nu belaget rakt ovanfOr satet 2, som i sin tur ãr belaget ovanfOr bottenramens 1 framre &ride 18. Satets 2 bakre ande 21 ãr nu belagen i en position ovanfOr satets 2 framre &ride 20. Vid uppres- ningen av satet 2 och ryggstadet 3 farflyttas glidkrop- pens 12 fOrsta ande Over till den ovre lankarmen 6, sá att glidkroppens 12 andra &ride 23 nu bef inner sig vid den tredje vridningspunkten C. I samband med uppresningen vrids den nedre lankarmen 9 kring den fjarde vridnings- punkten D, sa att den nedre lankarmens 9 ovre, forsta ande 10 applicerar en tryckande kraft pa den ovre lankarmens 6 andra &ride 8, vilken kraft gor att vridningspunkten C och den ovre lankarmen 6 kommer att medvridas i en uppatgaende rorelse. Detta gar att armlanksystemet under rftelsen kommer att halla armelementet 4 i en konstant orienteringsriktning, som gar att armstOdets 13 orienteringsriktning kommer att bibehallas horisontellt under hela lyftrarelsen av satet 2 och ryggstodet 3. Figure 3 shows the device in a stalage, where the armrest 13 is horizontal and where both the seat 2 and the backrest 3 are vertical. The backrest 3 is now located directly above the seat 2, which in turn is located above the front frame 1 of the bottom frame 1. The rear end 21 of the seat 2 is now located in a position above the front & ride 20 of the seat 2. 3, the first spirit of the sliding body 12 is moved over to the upper lance arm 6, so that the second & ride 23 of the sliding body 12 is now located at the third pivot point C. In connection with the erection, the lower lance arm 9 is rotated about the fourth pivot point D, so that the upper, first end 10 of the lower long arm 9 applies a compressive force to the second & ride 8 of the upper long arm 6, which force causes the pivot point C and the upper long arm 6 to be rotated in an upward movement. This means that during the movement the armrest system will keep the arm element 4 in a constant orientation direction, which means that the orientation direction of the armrest 13 will be maintained horizontally during the entire lifting movement of the seat 2 and the backrest 3.

Med uppfinningen uppnas att armstOdet 13 hela tiden bibehailer sin horisontella orienteringsriktning oavsett vilken lutningsvinkel ryggstodet 3 och satet 2 innehar. With the invention it is achieved that the armrest 13 constantly maintains its horizontal direction of orientation regardless of the angle of inclination of the backrest 3 and the seat 2.
