Description

AKTIVNI STOLACTIVE TABLE

Predmet izuma je aktivni stol, ki s svojo konstrukcijo omogoča gibanje sedala v vseh smereh in tako omogoča aktivno sedenje ter odpravlja pomanjkljivosti vseh, nam znanih dosedanjih rešitev za zdravo in pravilno držo telesa pri sedenju, vključno z žogo za sedenje in stolom na vzmeteh.The object of the invention is an active chair, which by its design allows the seat to move in all directions, thus allowing active sitting and eliminates the shortcomings of all known solutions to a healthy and proper body posture when sitting, including a seat ball and a chair on springs.

Predložen izum uspešno rešuje problem aktivnega sedenja s svojo enkratno, enostavno in pregledno konstrukcijo, ki omogoča optimalno stanje celega telesa pri sedenju, njegova izvedba pa je zelo primerna za industrijsko proizvodnjo in uporabo na različnih področjih.The present invention successfully solves the problem of active sitting with its unique, simple and transparent construction, which allows the optimal condition of the whole body when sitting, and its implementation is very suitable for industrial production and use in various fields.

Ravnotežje pri človeku lahko definiramo kot aktivno kompenzacijo, ki jo oseba doživlja, ali pa kot anticipacijo nasprotujočih se zunanjih motenj.Equilibrium in humans can be defined as active compensation experienced by the person or as anticipation of conflicting external disorders.

Ravnotežje živega telesa je upravljano z notranjimi telesnimi silami kot so mišični tonus, spremembe napetosti mišic itd. Za človeško telo, ki je sicer fizikalno v stabilnem ravnotežnem položaju velja, da je zelo podvrženo motnjam. Pri motenem ravnotežju pa telo lahko odgovori s povečano intimno oporo kot so mišična moč, natančnejša odzivnost, menjava položaja itd. Zunaji dejavniki pa so znižanje težišča in povečana podporna ploskev.The balance of a living body is controlled by internal body forces such as muscle tone, changes in muscle tension, etc. A human body that is physically in a stable equilibrium position is considered to be highly susceptible to interference. With impaired balance, however, the body can respond with increased intimate support such as muscle strength, more precise responsiveness, position changes, etc. External factors, however, are a decrease in the center of gravity and an increased support surface.

Živi organizmi, kakor tudi človeško telo delujejo tako, da z celo vrsto mehanizmov ohranjajo in varujejo stabilnosti, to je se upirajo spremembam. Občasno pa morajo živčni sistemi slediti spremembam telesnega položaja oz. jih voditi.Living organisms, as well as the human body, function to maintain and protect stability through a variety of mechanisms, that is, to resist change. Occasionally, however, nervous systems need to keep track of changes in their physical position. to guide them.

Če želimo dober nadzor nad držo moramo imeti dober stabilizatorski mehanizem, ki ohranja in varuje stabilnost. Torej želimo, da je stabilizacijski mehanizem čim bolj aktiven, da nastane čim manj motenj. Motnje pa morajo biti čim manjše, da ne pride do nepotrebnega izgubljanja energije zaradi sprememb. Vsako telo strmi k temu, da ohranja svoje notranje okolje čim bolj stabilno, ob tem pa porabi čim manj energije. To uspe tako, da čim prej prepozna motnjo in jo uravna.If we want good posture control we need to have a good stabilizer mechanism that maintains and protects stability. So we want the stabilization mechanism to be as active as possible so as to minimize interference. However, the disturbance must be kept to a minimum so that no unnecessary loss of energy is caused by the changes. Each body strives to keep its internal environment as stable as possible while consuming as little energy as possible. It succeeds by recognizing and correcting the disorder as soon as possible.

Zelo pomembno je, da je telo ves čas aktivno, motnja pa mora biti čim manjša, da ne porablja odvečne energije. Če želimo dober nadzor nad držo, moramo imeti dober stabilizatorski mehanizem, ki ohranja in varuje stabilnost. Torej želimo, da je stabilizacijski mehanizem čim bolj aktiven, da nastane čim manj motenj. Motnje pa morajo biti čim manjše, da ne pride do nepotrebnega izgubljanja energije zaradi sprememb. Vsako telo strmi k temu, da ohranja svoje notranje okolje čim bolj stabilno, ob tem pa porabi čim manj energije. To uspe tako, da čim prej prepozna motnjo in jo uravna.It is very important that the body is active at all times and the disorder should be kept to a minimum so that it does not consume excess energy. If we want good posture control, we need to have a good stabilizer mechanism that maintains and protects stability. So we want the stabilization mechanism to be as active as possible so as to minimize interference. However, the disturbance must be kept to a minimum so that no unnecessary loss of energy is caused by the changes. Each body strives to keep its internal environment as stable as possible while consuming as little energy as possible. It succeeds by recognizing and correcting the disorder as soon as possible.

Številne okvare na telesu so danes posledica premajhnih telesnih aktivnosti ljudi, med drugim v veliki meri zaradi sedenja. Za sedenje so na razpolago različne vrste stolov, ki imajo eno skupno lastnost: omogočajo samo pasivno sedenje. Pasivno sedenje opredelimo z opornimi točkami teh stolov: nasloni, naslonjala, noge, ki posredujejo telesu informacije o podpornih točkah. S tem popačijo naravno informacijo, usmerjeno v stalno iskanje naravnega ravnovesja.Numerous impairments of the body today are due to the lack of physical activity of people, among other things, largely due to sitting. There are different types of chairs available for seating that have one thing in common: they allow only passive seating. Passive seating is defined by the support points of these chairs: backs, backrests, legs, which provide the body with information about the support points. In doing so, they distort natural information aimed at the constant search for a natural balance.

Telo dobi informacijo o doseženem ravnovesju telesa, kar pa ni točno. Reakcija telesa je, da mišic ne napreza več ampak opusti njihovo dejavnost. Tako postanejo mišice pretežno neaktivne v svojem nenaravnem položaju. Zato težo telesa nosijo vretenca in medvretenčne ploščice; ker se to ponavlja zelo pogosto pride sčasoma do okvar na telesu. Nasprotno pa aktivacija mišic trupa, predvsem obhrbteničnih in trebušnih globokih mišic pomeni, da težo telesa nosijo pretežno mišice, posledično pa se razbremeni hrbtenica, to je vretenca in medvretenčne ploščice, kar je koristno.The body receives information about the achieved body balance, which is not accurate. The reaction of the body is that the muscles no longer strain but stop their activity. Thus, the muscles become largely inactive in their unnatural position. Therefore, body weight is borne by the vertebrae and the intervertebral discs; because this is very often repeated over time, there are body defects. In contrast, the activation of the trunk muscles, especially the backbone and abdominal deep muscles, means that the body weight is carried predominantly by the muscles, and consequently the spine, i.e. the vertebra and the intervertebral discs, is relieved, which is beneficial.

Znani rešitvi problema neaktivnih mišic pri sedenju sta opisani v SI20508 in WO 2011/142727.Known solutions to the problem of inactive sitting muscles are described in SI20508 and WO 2011/142727.

Pomanjkljivosti navedenih rešitev aktivnega stola so v tem, da stol ne provocira mehanizmov, ki ohranjajo stalnost. Pri sedenju na znanih aktivnih stolih prihaja do nenehnega rušenja nadzora nad držo oz. do popačenja informacij o tem. Stol sledi motnji in lahko dodatno poslabša nadzor nad držo. Uporabnik znanih stolov torej lahko ohranja stabilnost brez kakršnekoli aktivnosti tudi, če je živčno mišična aktivnost enaka spečemu človeku, ker je upornost materiala že dovolj, da oseba ostane na stolu. To pomeni, da na ravnotežnem stolu ni aktivacije globikh mišic in posledične stabilnosti, ki bi vodila v kvaliteten nadzor nad držo.The disadvantages of these active chair solutions are that the chair does not provoke mechanisms that maintain permanence. When sitting on known active chairs, there is a constant collapse of the posture control. to distort information about it. The chair follows the disorder and can further impair posture control. The user of known chairs, therefore, can maintain stability without any activity even if the neuromuscular activity is the same as that of a sleeping person, because the resistance of the material is already sufficient for the person to remain in the chair. This means that there is no activation of the deep muscles on the balance chair and consequent stability that would lead to quality posture control.

Naslednja znana rešitev je opisana v patentu SI21114. Stol ima osnovo izdelano kot krogelni odsek, vendar je pretirano nestabilen in ne omogoča prilagajanja ravnine sedala ravnini tal.Another known solution is described in patent SI21114. The chair has a base designed as a ball section, but is excessively unstable and does not allow the seat plane to adjust to the ground plane.

Naloga in cilj izuma je takšna konstrukcija stola, ki bo od človeka uporabnika zahtevala stalno senzorično in mišično aktivnost.The object and object of the invention is such a construction of a chair that will require constant human sensory and muscular activity from the human user.

Po izumu je problem neaktivnih senzorjev in mišic pri sedenju človeka rešen z aktivnim stolom po neodvisnem patentnem zahtevku.According to the invention, the problem of inactive sensors and muscles when seated is solved by an active chair according to an independent claim.

Izum bo opisan z izvedbenima primeroma in slikami, ki prikazujeje:The invention will be described with embodiments and figures, showing:

Stol po izumu sestavljajo osnova 2, drog 3, zglob 4 in sedalo 5. Stol je postavljen na tla 1.The chair according to the invention consists of a base 2, a pole 3, a joint 4 and a seat 5. The chair is placed on the floor 1.

Spodnji del osnove 2 je v izvedbenem primeru oblikovan kot krogelni odsek z radijem dolžine od 31 do 50 cm, katerega okroglina je obrnjena proti tlom 1. Navedena dolžina radija zagotavlja, da ostane oddaljenost sedala 5 od tal 1 vedno enaka oziroma se zanemarljivo malo spreminja, v primeru, ko se stol premakne iz središčne lege. Spodnji del osnove 2 je osno simeritčen. Gornja ploskev osnove 2 je oblikovana poljubno, vendar prednostno osno simetrično. To pomeni da je gornja ploskev lahko ravna, konična, piramidna, obla ali karšnekoli drugačne oblike. V sredini, to je v osi osnove 2 je na gornjo ploskev osnove 2 pritrjen drog 3. Drog 3 je na osnovo pritrjen čvrsto, vendar prednostno snemljivo. Drog 3 je poljubne oblike, njegova dolžina pa je tolikšna, da skupaj z osnovo 2, zglobom 3 in sedalom 5 omogoča primerno višino za sedenje človeka. Drog 3 je lahko po svoji dolžini na znane načine spremenljiv, s tem je omogočena prilagoditev višine stola višini človeka uporabnika. Zglob 4 je vstavljen med drog 3 in sedalo 5 in omogoča spremembo kota med smerjo droga 3 in ravnino sedala 5. Zglob 4 omogoča spremembo kota med drogom 3 in ravnino sedala 5 prednostno do 16°. Zglob 4 je izdelan tako, da se z večanjem kota med drogom 3 in ravnino sedala 5 povratna sila zgloba 4 povečuje. To pomeni, da se sila, s katero zglob 4 skuša vrniti stol po izumu v verikalen položaj, s kotom odklona od vertikale povečuje.In the embodiment, the lower portion of the base 2 is formed as a ball section with a radius of 31 to 50 cm, the circumference of which is facing the ground 1. The said radius length ensures that the distance of the seat 5 from the floor 1 is always the same or negligible. when the chair moves out of the center position. The bottom of base 2 is axially symmetrical. The upper surface of base 2 is formed arbitrarily but preferably axially symmetrically. This means that the top surface can be straight, conical, pyramid, round or any other shape. In the center, that is, in the axis of the base 2, a pole 3 is attached to the upper surface of the base 2. The bar 3 is fixed firmly but preferably detachably to the base. The mast 3 is of any shape and its length is such that, together with the base 2, the hinge 3 and the seat 5, it provides a suitable height for a person to sit. The rod 3 can be variable in its known length, which allows the height of the chair to be adjusted to the height of the human user. The hinge 4 is inserted between the mast 3 and the seat 5 and allows the angle between the direction of the bar 3 and the plane of the seat 5 to be changed. The wrist 4 is constructed in such a way that, by increasing the angle between the bar 3 and the plane of the seat 5, the return force of the wrist 4 increases. This means that the force exerted by the joint 4 to return the chair according to the invention in a vertical position increases with the angle of deviation from the vertical.

V prvem izvedbenem primeru po sliki 3 je zglob 4 izdelen z ležajem, kjer je skozi centričnoIn the first embodiment of Figure 3, the joint 4 is made with a bearing, where it is centered

odprtino v krogli 6 vstavljen nastavek 8, ki je na gornji strani pritrjen na sedalo 5, na spodnji strani pa na vzmetno palico 9. Krogla 6 je vrtljivo vpeta v okvir 7. Vzmetna palica 9 sega v notranjost droga 3. V notranjosti droga 3 je regulator 10. Regulator 10 je po obliki svoje zunanje površine prilagojen obliki notranje površine droga 3 tako, da se regulator 10 lahko pomika po dolžini v notranjosti droga 3. Regulator 10 ima v svoji sredini izvrtino, ki je po svoji obliki prilagojena obliki vzmetne palice 9 tako, da se regulator 10 lahko pomika po palici 9. Palica 9 je vstavljena v izvrtino regulatorja 10. Regulator 10 je kontrolirano gibljiv po dolžini droga 3 in gaje mogoče na želeni poziciji fiksirati na drog 3, npr. z vijakom, ki je gibljiv po utoru vzdolž droga 3. Zglob 4 je lahko standarden sferični ležaj z aksialno nosilnostjo več kot 100 kg. Vzmetna palica je tipično premera 6 mm in prednostno jeklena.an opening in the ball 6 is inserted a nozzle 8, which is secured to the seat 5 on the upper side and to the spring rod 9 on the lower side. The ball 6 is pivotally mounted in the frame 7. The spring bar 9 extends into the rod 3. regulator 10. Regulator 10 is adapted to the shape of its outer surface by the shape of the inner surface of the bar 3, so that the regulator 10 can be moved lengthwise inside the bar 3. Regulator 10 has a bore in its center adapted to the shape of the spring bar 9. so that the regulator 10 can be moved around the rod 9. The rod 9 is inserted into the bore of the regulator 10. The regulator 10 is movably controlled along the length of the bar 3 and can be fixed to the bar 3 at the desired position, e.g. with a bolt that moves along the groove along the pole 3. The joint 4 can be a standard spherical bearing with an axial load of more than 100 kg. The spring bar is typically 6 mm in diameter and preferably steel.

Ko človek uporabnik stola po izumu sede na sedalo 5 in povzroči nagib stola, se nastavek 8 v krogli 6 pomakne za določen kot iz vertikale. Krogla 6 se zavrti v okvirju 7. Vzmetna palica 9 se upogne med nastavkom 8 in regulatorjem 10 ter skuša vrniti sedalo v pravi kot med ravnino sedala in drogom ter s tem vrniti stol v vertikalni položaj. Silo, ki vrača stol v vertikalni položaj, je mogoče uravnavati s položajem regulatorja 10. Pomik regulatorja 10 v smeri nastavka 8 poveča to silo, pomik regulatorja 10 v smeri osnove 2 pa silo zmanjša.When the human user of the chair according to the invention sits on the seat 5 and causes the chair to tilt, the nozzle 8 in the ball 6 moves by a certain angle from the vertical. The ball 6 is rotated in the frame 7. The spring bar 9 is flexed between the nozzle 8 and the regulator 10 and tries to return the seat to the right angle between the seat plane and the pole, thus returning the chair to a vertical position. The force that returns the chair to a vertical position can be controlled by the position of the regulator 10. The movement of the regulator 10 in the direction of the attachment 8 increases this force, and the movement of the regulator 10 in the direction of the base 2 reduces the force.

V drugem izvedbenem primeru po sliki 4 je zglob 4 izdelan iz elastičnega materiala, ki samodejno vrača kot med smerjo droga 3 in ravnino sedala 5 v izhodiščni, prednostno pravi kot. Na drogu 3 nasprotni strani je na zglob 4 čvrsto, vendar prednostno snemljivo pritrjeno sedalo 5. Zglob 4 je torej vpet med sedalo 5 in drog 3. Sedalo 5 je poljubno primerno znano sedalo. Elastični zglob po drugem izvedbenem primeru je lahko različnih oblik. Na sliki 5.1 je predtsavljen elastični zglob v obliki vrtenine s konkavno obliko plašča. Na sliki 5.2 je predstavljen elastični zglob v obliki vrtenine z ravno obliko plašča, to je obliko valja, sliki 5.3 je predstavljen elastični zglob v obliki vrtenine s konkavno obliko plašča in je preko tega elementa nataknjem še elastičen obroč 11. Sila, ki vrača stol v vertikalni položaj, je najmanjša v primeru elastičnega zgloba v obliki vrtenine s konkavno obliko plašča, in največja v primeru zgloba v obliki vrtenine s konkavno obliko plašča ter nataknjenim elastičnim obročem 11. Zglob 4 je izdelan iz gume trdote od 50 do 110 SHOR.In another embodiment of Figure 4, the joint 4 is made of an elastic material that automatically rotates the angle between the direction of the bar 3 and the plane of the seat 5 at the starting point, preferably the right angle. On the pole 3 opposite, there is a firm but preferably detachable seat 5 on the joint 4. The joint 4 is therefore clamped between the seat 5 and the pole 3. The seat 5 is a suitably known seat. The elastic joint of the second embodiment may be of various shapes. Figure 5.1 shows an elastic joint in the shape of a vortex with a concave mantle shape. Figure 5.2 shows an elastic joint in the form of a vortex with a flat mantle shape, that is, a cylinder, in Fig. 5.3 presents an elastic joint in the form of a vortex with a concave mantle, and through this element, an elastic ring 11 is inserted through the element. The vertical position is the smallest in the case of an elastic joint in the form of a concave-shaped vortex, and the largest in the case of a joint in the form of a concave-shaped conduit and an elastic ring 11. The joint 4 is made of 50 to 110 SHOR hard rubber.

Spodnji del osnove 2 je oblikovan kot krogelni odsek. Problem te oblike je nestabilnost stola pri neuporabi. Stol se prevrne tako, da je drog 3 skoraj vzporeden s tlemi 1. Rešitev je obtežitev osnove 2 v njenem osrednjem spodnjem delu. Druga rešitev je drugačna, ne-krogelna oblika spodnjega dela osnove 2. Spodnji del osnove 2 ima v sredini krog z zelo velikim polmerom, ki se proti robu zmanjšuje. Sredina spodnjega dela osnove 2 je tako skoraj ravna, proti robu pa je vedno bolj zaobljena. Vsekakor pa je spodnji del osnove 2 obel in osno simetričen. Vsekakor je spodnji del osnove 2 vrtenina oble oblike.The bottom of the base 2 is shaped like a ball section. The problem with this design is the instability of the chair when not in use. The chair rolls over so that the pole 3 is almost parallel to the ground 1. The solution is to load the base 2 in its central lower part. The other solution is a different, non-spherical shape of the lower part of base 2. The lower part of base 2 has a circle with a very large radius in the center, which decreases towards the edge. The center of the lower base of base 2 is thus almost straight, and is increasingly rounded towards the edge. In any case, the bottom of the base 2 is obel and axially symmetrical. In any case, the lower part of the base 2 is a circular shape.

Sedalo 5 zglob 4 samodejno izravnava v pravilno horizontalno pozicijo, ki hkrati predstavlja optimalno pozicijo sedenja. Zglob 4 nadalje nudi progresiven upor pri sedenju: bolj ko je stol in pozicija sedenja odmaknjena iz središča, večja sila je potrebna, da se sedalo5 izravna v horizontalno pozicijo. Upor zgloba je možno prilagoditi teži konkretnega človeka, zato, da je zadosten, da čim bolj stimulira mišice jedra in da daje telesu signal, kje je središče sedenja in posledično podzavestno spodbuja telo, da teži v osrediščen položaj. Zaradi varnosti ima zglob omejitev gibljivosti na največ 16 stopinj od pravega kota med smerjo droda 3 in ravnino sedala 5. Gibljivost je omejena ali s posebnim robom, na katerega se nasloni sedalo 5 ploskev ali pa s samim mehanizmom v zglobu 4. Spodnji del osnove 2 je v izvedbenem primeru v obliki kroglenega odseka z radijem dolžine od 31 do 50 cm, s katerim se dotika tal le v eni točki oz. v zelo majhnem delu oboda krogle. Osnova 2 ima iz varnostnih razlogov omejen nagib z obročem po obodu osnove 2, ki dovoljuje le nagibe manjše od 30° .Seat 5 hinge 4 automatically aligns to the correct horizontal position, which at the same time represents the optimum seating position. The joint 4 further provides a progressive seat resistance: the more the chair and the seating position move away from the center, the more force is required to align the seat5 to a horizontal position. The resistance of the joint can be adjusted to the weight of a particular person so that it is sufficient to stimulate the core muscles as much as possible and to give the body a signal about where the center of sitting is and consequently subconsciously stimulate the body to aspire to a central position. For safety reasons, the joint has a maximum movement limitation of up to 16 degrees from the right angle between the direction of the rod 3 and the plane of the seat 5. The mobility is restricted either by the special edge on which the saddle 5 rests or by the mechanism itself in the joint 4. Lower base 2 in the embodiment, it is in the form of a ball section with a radius of 31 to 50 cm, with which it touches the ground at only one point or. in a very small part of the circumference of the sphere. Base 2 has a restricted slope for safety reasons with a ring around the perimeter of base 2 that only allows slopes of less than 30 °.
