Description
STOL NA VIJAČNI VZMETI Z OMEJILNIKOM GIBANJACHAIR SPRING TABLE WITH MOVEMENT LIMITER
Predmet izuma je stol na vijačni vzmeti z omejilnikom gibanja, kjer je sedalo vpeto na podnožje preko vijačne vzmeti, ki sedalu omogoča nadzorovano nihanje. Takšen stol ima ortopedske lastnosti, saj posnema sedenje na žogi, kar je izjemno koristno za hrbtenico in hrbtne mišice.The subject of the invention is a chair on a helical spring with a limiting movement, where the seat is mounted on the base via a helical spring, which allows the seat to be controlled oscillation. Such a chair has orthopedic features, as it mimics sitting on a ball, which is extremely useful for the spine and back muscles.
Stol na vijačni vzmeti je znan iz patentov Sl 20455 in 20508. Sedalo 4 je pritrjeno platformo 5 na gornjem koncu vijačne vzmeti 1, ki je na svojem spodnjem koncu pritrjena preko nosilca 2 na podnožje 3 ali na ustrezen znan dvižno/spustni mehanizem. Tako je sedalo 4 gibljivo vertikalno v odvisnosti od teže osebe ki sedi, predvsem pa lahko približno krožno, z vrtiščem približno na polovici višine vzmeti, niha v vse smeri.The chair on the helical spring is known from the patents Figs 20455 and 20508. The seat 4 is a fixed platform 5 at the upper end of the helical spring 1, which is secured at its lower end via a carrier 2 to the base 3 or to a suitable known lifting / lowering mechanism. Thus, seat 4 is movable vertically, depending on the weight of the person seated, but above all, it can be circular, with a pivot about half the height of the spring, swinging in all directions.
Problem ki pri opisanem znanem stolu ni zadovoljivo rešen je, da je nihanje sedala lahko pretirano in povzroči nestabilnost ali celo zdrs s sedala in padec osebe ki sedi. Nihanje sedala je omejeno le s trdoto vzmeti.The problem that is not satisfactorily solved with the described chair is that the swinging of the seat can be excessive and cause instability or even slip from the seat and fall of the sitting person. The swing of the seat is limited only by the hardness of the spring.
Naloga in cilj izuma je preprečitev pretiranega nihanja sedala stola na vijačni vzmeti.The object and object of the invention is to prevent excessive swinging of the seat of the chair on the helical spring.
Po izumu je naloga rešena po neodvisnem patentnem zahtevku.According to the invention, the problem is solved according to an independent patent claim.
Izum bo opisan na izvedbenem primeru in slikah, ki prikazujejo:The invention will be described in the embodiment and in the drawings showing:

Na sliki 4 je prikazan detajl z omejilnikom gibanja stola na vijačni vzmeti po izumu v prerezu ko sedalo in platforma 5 nista stransko obremenja in sta horizontalna, to je paralelna s tlemi, na katerih stoji stol.Figure 4 shows a detail of a chair limiter on a screw spring according to the invention in cross-section when the seat and platform 5 are not laterally loaded and are horizontal, that is, parallel to the floor on which the chair stands.
Nosilec 2 je povezava s podnožjem, to je nogami stola in je hrati lahko mehanizem za reguliranje višine sedala 4 stola, to je za prilagajanje višine sedala 4 stola višini osebe, ki sedi. Na nosilec 2 je s svojim spodnjim koncem pritrjena vijačna vzmet 1. Na gornjem koncu vzmeti • ·Bracket 2 is a connection with the base, that is, the legs of the chair and can be a mechanism for adjusting the height of the seat 4 chairs, that is to adjust the height of the seat 4 chairs to the height of the person sitting. A screw spring 1 is attached to the carrier 2 by its lower end. At the upper end of the spring • ·
-21 je v njeno notranjost vstavljena prednostno pločevinasta, prednostno jeklena puša 8. Zunanji premer puše 8 je malenkost, to je od 0,1 do 0,5 mm manjši od notranjega premera vzmeti.-21 there is preferably a sheet metal, preferably a steel sleeve 8. The outer diameter of the sleeve 8 is small, ie 0.1 to 0.5 mm smaller than the inner diameter of the spring.
Puša 8 je v gornjem delu krožno prekrivljena navzven za pravi kot tako, da naleze na zaključek vzmeti 1 in jo delno objame ter hkrati polno naleže na platformo 5. Platforma 5 je pritrjena na vzmet 1 in pušo 8. Na platformo 5 se pritrdi sedalo 4 stola.The bush 8 is circularly folded outwards in the upper part so as to fit the spring end of the spring 1 and partially embrace it, while fully supporting the platform 5. The platform 5 is attached to the spring 1 and the bush 8. The platform 4 is secured to the seat 4 table.
V geometrijskem središču vzmeti 1 je na vrh nosilca 2 pritrjen drog 6. Drog 6 je čvrsta kovinska palica, pri čemer je ta lahko toga ali rahlo elastična. Dolžina droga je manjša od razdalje med vrhom nosilca 2 in spodnjo površino platforme 5 pri neobremenjeni vzmeti 1. Manjša dolžina droga od razdalje med vrhom nosilca 2 in spodnjo površino platforme 5 pri neobremenjeni vzmeti 1 je potrebna zato, da platforma 5 ne nasede na vrh droga 6 ob obremenitvi. Kot obremenitev je razumeti težo osebe, ki sede na stol. Trdota in prožnost vzmeti 1 je dimenzionirana v skladu z deklarirano največjo dovoljeno obremenitvijo stola, to je s težo osebe ki sedi.In the geometric center of spring 1, a pole 6 is attached to the top of the carrier 2. The pole 6 is a solid metal rod, which can be rigid or slightly elastic. The length of the bar is less than the distance between the top of the carrier 2 and the lower surface of the platform 5 in the unloaded spring 1. A smaller length of the rod than the distance between the top of the carrier 2 and the lower surface of the platform 5 in the unloaded spring 1 is required so that the platform 5 does not sit on the top of the bar 6 at load. It is a burden to understand the weight of a person sitting on a chair. The stiffness and flexibility of spring 1 is sized in accordance with the declared maximum permissible load on the chair, that is, with the weight of the person sitting.
Ta manjša dolžina droga 6 je torej opredeljena s skrčkom vzmeti 1 pri največji dovoljeni vertikalni obremenitvi sedala 4. Vzmet 1 se ob stranski obremenitvi, to je, ko na sedalo 4 stola sede oseba, upogne v stran, kot je prikazano na sliki 5. Ko je upogib vzmeti 1 dovolj velik in da nagib sedala 4 ne postane prevelik in s tem stol nestabilen, se puša 8 dotakne vrha droga 6 in s tem je preprečen nadaljnji nagib sedala 4. Notranji premer vzmeti 1 in s tem puše 8 ter premer ter višina droga 6 omejujeta nihanje sedala 4.This smaller length of pole 6 is therefore defined by the shrinkage of spring 1 at the maximum permissible vertical load of seat 4. Spring 1, when sidelined, that is, when a person sits on the seat of 4 chairs, bends to the side as shown in Figure 5. When the bending of spring 1 is large enough so that the inclination of the seat 4 does not become too large and thus the chair is unstable, the bushing 8 touches the top of the bar 6, thus preventing the further bending of the seat 4. The inner diameter of the spring 1 and thus the bushing 8 and the diameter and height pole 6 limits the swing of the seat 4.
Alternativno in v okviru izuma je mogoče na vrh droga 6 natakniti ležaj 7. Prednostno je to kroglični ležaj s takšnim notranjim premerom, da tesno nasede na vrh droga 6. Zunanji premer ležaja 7 je prilagojen dopustnemu nagibu sedala. V tej izvedbi se ležaj 7 lahko kotali po notranjosti puše 8. S tem je preprečeno neprijetno drgnjenje vrha droga 6 ob pušo 8. Notranji premer vzmeti 1 in s tem puše 8 ter zunanji premer ležaja 7 ter višina droga 6 omejujejo nihanje sedala 4.Alternatively and within the invention, a bearing 7 can be fitted to the top of the pole 6. Preferably, this is a ball bearing of such an internal diameter that it closely rests on the top of the pole 6. The outer diameter of the bearing 7 is adapted to the permissible inclination of the seat. In this embodiment, the bearing 7 can be rolled over the inside of the bushing 8. This prevents the tip of the bar 6 from sliding against the bushing 8. The inside diameter of the spring 1 and thereby the bushing 8 and the outer diameter of the bearing 7 and the height of the bar 6 limit the swing of the seat 4.
Alternativno in v okviru izuma je mogoče notranjost vzmeti 1 in puše 8 obdati s 5-10 mm debelo oblogo 9 elastičnega materiala, prednostno silikonske gume. S tem je zagotovljen prijeten, mehak in neslišen naslon vrha droga 1 ali ležaja 8, ki se naslonita na oblogo 9 in ne na pušo 8.Alternatively and within the scope of the invention, the inside of the spring 1 and the bush 8 can be enclosed with a 5-10 mm thick lining 9 of elastic material, preferably silicone rubber. This provides a comfortable, soft and audible support for the top of the mast 1 or the bearing 8, which rests on the lining 9 and not on the bush 8.
