Description

Predmet izuma je aktivni ortopedski stol, katerega konstrukcijska rešitev omogoča gibljivost sedala v vseh smereh in povzema funkcionalno tehniko sedenja na žogi, ter je z njim možno nadomestiti običajne pisarniške oziroma delovne stole. Izum spada v razreda A 47C 3/00 oz. AThe subject of the invention is an active orthopedic chair, whose design solution enables the seat to move in all directions and summarizes the functional technique of sitting on the ball, and it can be replaced with ordinary office or work chairs. The invention belongs to Class A 47C 3/00 oz. A

47C 9/00.47C 9/00.

Tehnični problem, ki ga predložen izum uspešno rešuje je konstrukcija in izvedba takšnega ortopedskega pripomočka, ki bo sam po sebi zaradi konstrukcijske značilnosti omogočal pravilno sedenje tako, da bo hrbtenica vedno v optimalnem položaju, njegova izvedba pa bo primerna za uporabo namesto običajnih pisarniških in drugih stolov.The technical problem that the present invention successfully solves is the construction and implementation of such an orthopedic device, which in itself due to its structural characteristics will allow proper sitting so that the spine is always in an optimal position, and its implementation will be suitable for use instead of ordinary office and other chairs.

Znane izvedbe običajnih stolov, ki nudijo le oporo in naslon telesu, v pogostih primerih pogojujejo in omogočajo nepravilno držo telesa pri sedenju, kar negativno vpliva na hrbtenico in jo dodatno obremenjuje.Known designs of conventional chairs, which provide only support and support to the body, in many cases condition and allow incorrect posture of the body when sitting, which negatively affects the spine and puts additional strain on it.

Poleg opisanih pasivnih pripomočkov za sedenje, ki ne zahtevajo 5 aktivnega odzivanja telesa pri sedenju pa so znane tudi konstrukcije pripomočkov za sedenje, ki posnemajo sedenje na krogli. Pri sedenju na krogli (žogi) mora biti telo vedno v pripravljenosti in vzdrževati ravnotežje. Na ta način so hrbtne mišice vedno napete, položaj hrbtenice pa je v idealni legi. V tej zvezi je znana izvedba pripomočka za sedenje, ki je opisana v EP dokumentu 0 563 820. V primernem ogrodju je postavljena večja napihljiva žoga, medtem ko iz nosilnega ogrodja izhaja tudi opornik za hrbet. Ta konstrukcijska rešitev sicer rešuje zastavljen tehnični problem v smislu aktivnega sedenja, izvedba sama pa ne omogoča izdelavo primernih in uporabnih vsakdanjih pripomočkov za sedenje, is predvsem zaradi velikosti in okornosti.In addition to the passive sitting aids described, which do not require 5 active body response when sitting, the constructions of sitting aids that mimic sitting on a ball are also known. When sitting on a ball, the body should always be on standby and maintain balance. This way the spinal muscles are always tense and the spine position is ideally positioned. In this connection, the embodiment of the sitting aid described in EP document 0 563 820 is known. A larger inflatable ball is placed in the appropriate frame, while the backrest also extends from the supporting frame. This construction solution solves the stated technical problem in terms of active sitting, but the implementation alone does not allow the production of suitable and useful everyday sitting aids, and mainly because of the size and cushioning.

Znane so tudi konstrukcije, ki omogočajo premikanje sedežnega dela stola v vseh smereh v ravnini. Paleta takšnih rešitev je podana v dokumentih WO 93/19645, WO 93/19646, WO 93/19647, WO 93/19648. Rešitve v teh dokumentih ponujajo različne konstrukcije, ki pa soAlso known are structures that allow the seat of the chair to be moved in all directions in the plane. An array of such solutions is provided in documents WO 93/19645, WO 93/19646, WO 93/19647, WO 93/19648. The solutions in these documents offer different constructs, which they are

2o zapletene za izdelavo, imajo veliko število gibljivih in medsebojno drsečih delov.2o complicated to manufacture, they have a large number of moving and mutually moving parts.

Iz dokumenta WO 92/01410 pa je znana tudi rešitev, ki predvideva poseben, v vse smeri v ravnini drseč nastavek, na podnožju normalnega delovnega stola, ki ravno tako zahteva aktivno sedenje.Document WO 92/01410 also discloses a solution which provides a special, in all planar, sliding attachment, at the base of a normal work chair, which also requires active seating.

Vse opisane rešitve sicer rešujejo problem aktivnega sedenja, to je 5 sodelovanja hrbtnih mišic pri sedenju in postavljanja hrbtenice v optimalen položaj, vendar zaradi oblikovnih in/ali konstrukcijskih značilnosti niso najbolj primerne za široko uporabo tako pri pripomočkih za sedenje v pisarni ali doma, ali pa so zaradi zapletene konstrukcije in velikega števila sestavnih delov v bistvu nezanimive za izdelavo, ker so predrage ali pa io zahtevajo preveč vzdrževanja.All of the solutions described do solve the problem of active sitting, that is, 5 involvement of the back muscles in sitting and placing the spine in an optimal position, but because of their design and / or design features, they are not best suited for widespread use in office or home sitting aids, or Due to their complex construction and large number of components, they are essentially uninteresting to manufacture because they are too expensive or require too much maintenance.

Pri aktivnem ortopedskem stolu po izumu, ki v bistvu povzema tehniko sedenja na žogi in je funkcionalno izveden kot pisarniški oziroma delovni stol, je sedalo povezano preko elementa, ki omogoča gibljivost le-tega v vseh smereh, z podnožjem. Element, ki omogoča gibljivost je lahko is vijačna vzmet, prožni element ali drsni mehanizem.In the active orthopedic chair according to the invention, which essentially follows the technique of sitting on a ball and is functionally implemented as an office or work chair, the seat is connected via an element that allows it to move in all directions, with the base. The movable element may be a helical spring, a flexible element or a sliding mechanism.
