Abstract

Prestavitelná stolička s kolennou opierkou je určená na sedenie pri činnostiach, vyžadujúcich dlhodobé sedenie v předklone pre rysovanie pri stole, resp. tabuli. Opretie kolena o kolennú opierku prenáša časť hmotnosti trupu a znižuje namáhanie chrbtového svalstva a chrbtice v krížovej a bedrovej oblasti a tým i celková únavu. Výšková a uhlová prestavitelnosť sedadla, výšková, uhlová, stranová a pozdížna prestavitelnosť kolennej opierky umožňuje prisposobenie každej výške postavyAdjustable chair with knee support is designed for sitting during activities that require prolonged sitting in a forward bend for drawing at a table or. blackboard. Resting the knee on the knee support transfers part of the weight of the torso and reduces the strain on the back muscles and spine in the sacrum and lumbar region and thus overall fatigue. The height and angle adjustability of the seat, the height, angle, lateral and longitudinal adjustability of the knee support allow adaptation to any height of the body

Description

Vynález sa týká prestavitelnej stoličky s kolennou opierkou, ktorá znižuje namáhanie krížovej a bedrovej časti chrbtice a umožňuje prispůsobenie sa k různým výškám postáv.The invention relates to an adjustable knee-support chair that reduces stress on the cross and lumbar spine and allows adjustment to the different heights of the figures.

V súčasnosti sa pri prácach, vyžadujúcich trvalú sediacu polohu pracovníka, vačšinou používajú stoličky s chrbtovým operadlom. Mnoho druhov práč, ako například kresleme při rysovacom stole, kreslenie pri rysovacej tabuli a podobné činnosti, znemožňuje sedenie s opretým chrbtom aj opretie rukami o stol. V týchto prípadoch drží hmotnost předkloněného trupu chrbtové svalstvo a chrbtica v krížovej a bedrovej oblasti. Dlhodobé statické namáhanie týchto partií a neprirodzené oblúkovité prehnutie chrbtice má za následok nepriaznivé namáhanie stavcov a medzistavcových platničiek a v mnohých prípadoch trvalé deformácie.Presently, chairs with a backrest are usually used for work requiring a permanent sitting position. Many types of washing, such as drawing on a drawing table, drawing on a drawing board, and similar activities, make it impossible to sit with your back and to rest your hands on the table. In these cases, the weight of the bent torso holds the back muscles and spine in the sacrum and lumbar region. Prolonged static stress on these parts and unnatural arched spine deflection results in unfavorable stress on vertebrae and intervertebral discs and in many cases permanent deformation.

Uvedené nedostatky odstraňuje prestavitelná stolíčka s kolennou opierkou, ktorá sa skládá z podstavca, stojin, zasúvacích stojin, objímok so stavacími skrutkami, nastavovacích čapov, sedadla a kolennej opierky. Sedadlo je výškovo a uhlovo prestavítelné a kolenná opierka je výškovo, uhlovo, stranovo i pozdlžne prestaviteíná. Možnost nastavenia polohy sedadla a kolennej opierky umožňuje individuálně prispůsobenie každej výške postavy. Pri sedávej činnosti s použitím stoličky s kolennou opierkou ,sa vSCšia časť hmotností trupu prenáša na koleno, ktoré sa opiera o kolennú opierku. Tým sa odlahčuje chrbtové sva’stvo a chrbtica v krížovej a bedrovej oblastí, čo umožňuje vzpriamenú polohu chrbta a prirodzené esovité prehnutie chrbtice. Stranová přestavitel,nosť kolennej opierky vylučuje jednostranné namáhanie len jednej nohy.The above-mentioned drawbacks are eliminated by an adjustable knee-support table, which consists of a pedestal, uprights, retractable legs, collar with set screws, adjusting pins, seat and knee support. The seat is height and angular adjustable and the knee support is height, angular, lateral and longitudinally adjustable. Adjustable seat and knee support allows for individual height adjustment. When sitting down using a knee-support chair, most of the weight of the torso is transmitted to the knee, which rests on the knee support. This relieves the back and spine in the sacrum and lumbar region, allowing the back to be upright and the natural S-shaped backbone. Side adjuster, knee support eliminates unilateral stress on only one leg.

Vynálezom sa znižuje statické namáhanie chrbtového svalstva a chrbtice v krížovej a bedrovej oblasti a znižuje sa únava pri sedavých čínnostiach.The invention reduces the static stress on the back and spine in the sacrum and lumbar region, and reduces fatigue in sedentary cramps.
