Abstract

The rotating enclosure with spring-fitted wheel (5) solves the problems of instability positions of vacuum cleaners (3) where the solving of instability is implemented by a spring-based vertical displacement of the axis (31) and wheel (25) against the vacuum-cleaner enclosure due to the load of the vacuum cleaner (3) exerted against the rotating enclosure with spring-based wheel (5) which is aimed at transferring the weight of the vacuum-cleaner (3) onto the surface (11). By a vertical displacement of the axis (31) and the wheel (25), the transfer of the weight of the vacuum cleaner (3) to the surface is enabled. Via two rotating enclosures with spring-based wheels (5) attached to the vacuum cleaner (3) a stable position of the vacuum cleaner (3) on the surface (11) is ensured.

Description

VZMETENO KOLO V VRTLJIVEM OHIŠJUSPRING WHEEL IN A SWITCH

Predmet izuma je vzmeteno kolo v vrtljivem ohišju, prvenstveno sestavni del sesalnika za prah, ki služi za lažje vodenje sesalnika za prah po talni površini, pri čemer je kolo vpeto v vrtljivo ohišje tako, da mu je omogočen poleg osnovnih rotacij tudi premik kolesa v vertikalni smeri proti telesu sesalnika za prah.The subject of the invention is a spring wheel in a rotary casing, primarily an integral part of a dust vacuum cleaner, which is used to facilitate the guidance of a dust vacuum cleaner on the floor surface, whereby the wheel is mounted in a rotary housing so that, in addition to its basic rotations, it can also move the wheel vertically towards the body of the vacuum cleaner.

Kolo po izumu rešuje problem naleganja sesalnika za prah na neravni površini, prav tako pa rešuje stabilnost sesalnika za prah med uporabo parkiranja sesalne cevi z nastavki na sesalnik za prah. Značilnost rešitve po izumu je, da je konstrukcija izredno enostavna za izvedbo in zavzema malo prostora.The bicycle according to the invention solves the problem of fitting the dust cleaner on a uneven surface and also solves the stability of the dust vacuum cleaner when using the suction pipe parking with the attachments on the dust cleaner. A feature of the solution according to the invention is that the construction is extremely easy to implement and takes up little space.

Znane so rešitve za vrtljiva ohišja s kolesi kot npr. Patent GB 1184136 pri čemer je poglavitna funkcija vrtljivega ohišja s kolesi lažje sledenje uporabniku in obračanje sesalnika za prah med uporabo. Prav tako pa poznamo tudi rešitve po patentih EP 0439465 (B1) in US 4509227 vrtljivih ohišij s kolesi z dodatnimi vrtljivimi elementi za prevzemanje obremenitve z vrtljivega ohišja na samo telo sesalnika za prah. Znana je tudi rešitev po JP 4117929, ki dodatno omogoča blaženje kolesa in njegov pomik proti telesu sesalnika za prah v primeru obremenitve. Omenjena rešitev pa je nepraktična in draga, saj zahteva dodatne elemente v sestavu, ki omogočajo funkcijo blaženja, prav tako pa zahteva za izvedbo mnogo prostora.Known solutions for rotating wheel housings such as e.g. GB 1184136 patent, with the main function of the rotary wheel housing being easier to track the user and turn the vacuum cleaner into use. We also know the solutions of EP 0439465 (B1) and US 4509227 wheels with wheel rotors with additional rotating elements to take the load from the rotating housing to the body of the vacuum cleaner. Also known is a JP 4117929 solution, which additionally allows the wheel to be damped and moved towards the body of the vacuum cleaner in the event of a load. This solution, however, is impractical and expensive because it requires additional elements in the assembly that provide a damping function and also requires a lot of space.

Sesalnik za prah je sestavljen iz telesa sesalnika za prah v kateri je nameščen motor, ki s turbino proizvaja zračni tok, ki preko sistema sesalnih nastavkov, trde cevi in gibljive cevi, prenaša prah, ki je bil odvzet na čistilni površini in ga preko omenjenega sistema transportira v zbiralni prostor, ki je nameščen v telesu sesalnika za prah, ki je lahko izveden v obliki vrečke s prepustno površino ali v obliki ciklonskega zbiralnika. Sesalnik na tla nalega preko koles, ponavadi gre za dve zadnji kolesi, ki sta vrtljivi okoli osi, ki je prečna na os sesalnika za prah in sprednje kolo, ki je vpeto v vrtljivo ohišje. Samo prednje kolo tako rotira okoli osi, ki leži vzporedno z ravnino tal in je od nje oddaljena za polmer kolesa, in je obenem vpeta v vrtljivo ohišje. Vrtljivo ohišje rotira okoli osi vertikalno na ravnino tal, pri čemer je os vrtenja sprednjega kolesa od osi vpetja vrtljivega ohišja oddaljena za razdaljo X. Sesalniki za prah so povečini opremljeni z enim vrtljivim ohišjem s kolesom, poznamo pa tudi sesalnike za prah z dvema ali več vrtljivimi ohišji s kolesi. Pri uporabi dveh vrtljivih ohišij s kolesi, ko imamo skupaj najmanj štiri kolesa na sesalniku za prah, je značilno to, da se poveča stabilnost sesalnika za prah predvsem na račun medosne razdalje med vrtljivimi ohišji, pri čemer se izboljša tudi vodljivost in okretnost sesalnika za prah med uporabo. Problem, ki se pojavlja med uporabo sesalnika za prah z dvema ali več vrtljivimi ohišji s kolesi pa je ta, da se zaradiThe dust vacuum cleaner consists of a body of a dust vacuum cleaner in which an engine which produces an air stream is installed by means of a turbine which, through a system of suction nozzles, rigid tubes and flexible hoses, carries the dust collected on the cleaning surface and through the said system is transported to a collection area located in the body of a vacuum cleaner, which can be in the form of a bag with a permeable surface or in the form of a cyclone reservoir. The vacuum cleaner rests over the wheels, usually two rear wheels that rotate about an axis transverse to the axis of the vacuum cleaner and a front wheel that is mounted in a rotating housing. Only the front wheel thus rotates about an axis which lies parallel to the ground plane and away from it by the radius of the wheel, and at the same time is mounted in a rotating housing. The rotary housing rotates about an axis vertically to the ground plane, with the axis of rotation of the front wheel spaced from the axis of rotation of the rotating housing by a distance of X. The vacuum cleaners are generally equipped with one rotary housing with a wheel, and we also know dust extractors with two or more wheels with rotating housings. When using two rotating wheel housings with a total of at least four wheels on a dust vacuum cleaner, it is characterized by increasing the stability of the dust vacuum cleaner, mainly at the expense of wheelbase between the rotary housings, while also improving the handling and agility of the dust vacuum cleaner. during use. The problem with using a vacuum cleaner with two or more rotating wheel housings is that due to the

-2neravne podlage sesalnik za prah lahko nekontrolirano ziblje in daje vtis nestabilnosti. Prav tako pa se pri teh izvedbah pojavljajo udarci kolesa na podlago kot posledica zibanja sesalnika za prah na podlagi, kar škoduje konstrukciji sesalnika za prah in povzroča moteč hrup. Sesalniki za prah z uporabo dveh vrtljivih ohišij s kolesi imajo tako večjo stabilnost proti prevračanju, nimajo pa statične stabilnosti, saj se pri neravnih tleh pojavlja problem, ker eno kolo- ponavadi je to eno izmed spredaj vpetih vrtljivih koles lebdi prosto v zraku. Poznamo pa tudi sesalnike za prah, ki tudi zadnja kolesa nadomestijo z vrtljivimi ohišji s kolesi, ter tako dobimo sesalnike za prah s štirimi ali več vrtljivimi ohišji s kolesi, pri čemer pa je vodljivost in stabilnost sesalnika manjša.-2Non-flat substrates The vacuum cleaner can swing uncontrollably and give the impression of instability. In these embodiments, wheel bumps also occur on the ground as a result of the rocking of the vacuum cleaner on the ground, which damages the construction of the dust vacuum cleaner and causes annoying noise. Dust vacuum cleaners with two rotating wheel housings thus have greater stability against rollover but lack static stability, since uneven floors are a problem because one wheel - usually one of the front-mounted rotating wheels - is floating freely in the air. Dust vacuum cleaners are also known to replace rear wheels with rotating wheel housings to provide dust cleaners with four or more rotating wheel housings, with less handling and stability.

Naloga in cilj izuma je takšna konstrukcija vzmetenega kolesa v vrtljivem ohišju, ki bo sesalniku za prah zagotavljala stabilnost in vodljivost.It is an object and object of the invention to provide such a design of a spring wheel in a rotary casing, which will provide the vacuum cleaner with stability and controllability.

Po izumu je naloga rešena z vzmetenim kolesom v vrtljivem ohišju po neodvisnem patentnem zahtevku.According to the invention, the problem is solved by a suspension wheel in a rotary casing according to an independent claim.

Samo vrtljivo ohišje z vzmeteno vpetim kolesom 5 po sliki 1 je sestavljeno iz vrtljivega ohišja 15, kolesa 25, vzmeti 33 in osi kolesa 31 kot prikazuje slika 3. Pri sestavi vrtljivega ohišja 15 z vzmeteno vpetim kolesom 5 je značilno to, da je vzmet 33, ki potiska os 31 v ležišču vrtljivega ohišja 36 vpeta v samem vrtljivem ohišju 15 in deluje na os 31 kolesa 25, kot reakcija na vpeti točki. Pri premiku osi 31 kolesa 25 v utoru 36 in s tem tudi kolesa 25, ki je nastavljen na os 31 se vzmet 33 poda in s tem deluje na os 31 kolesa 25 z večjo silo. Sama os 31 kolesa 25 se med pomikom po utoru 36 ne vrti, vrti pa se kolo 25, ki je na os 31 vpeto. Z preobremenitvijo sile na telo sesalnika za prah, ki je znatno večja kot sama masa sesalnika za prah z napolnjeno vrečko, se os 31 kolesa 25 poda do zgornjega prečnega rebra 22, kjer se os 31 nasloni na prečno rebro 22 in ne dopušča, da bi se kolo 25 naslonilo na telo sesalnika za prah 3.Only a rotatable housing with a spring-mounted wheel 5 of Figure 1 consists of a rotatable housing 15, a wheel 25, a spring 33, and a wheel axis 31 as shown in Figure 3. When assembling a rotary housing 15 with a spring-mounted wheel 5, it is characterized that the spring 33 , which pushes the axis 31 in the bearing of the rotary housing 36 clamped in the rotary housing itself 15 and acts on the axis 31 of the wheel 25 as a reaction at the clamping point. When the axle 31 of the wheel 25 in the groove 36 is displaced, and thus the wheel 25, which is adjusted to the axle 31, the spring 33 is actuated, thereby acting on the axle 31 of the wheel 25 with greater force. The axis 31 of the wheel 25 itself does not rotate while moving through the groove 36, and the wheel 25, which is mounted on the axis 31, rotates. By overloading the force on the body of the vacuum cleaner, which is substantially larger than the mass of the dust bag filled with the bag, the axis 31 of the wheel 25 extends to the upper transverse rib 22, where the axis 31 rests on the transverse rib 22 and prevents the wheel 25 rests on the body of the vacuum cleaner 3.

-3Ohišje 15 je prednostno krožnega preseka z valjastim nastavkom na sredini za pritrditev ohišja 15 na nosilno os na telesu sesalnika 3. Na eni strani ohišja 15 sta njegov plašč in del dna odprta v približni velikosti kolesa 25. Ta odprtina je ograjena in tvori dva vertikalna utora 36, ki sta vodilo osi 31 kolesa 25 in določata prosti vertikalni pomik osi 31 in kolesa 25 proti telesu sesalnika 3. Pomik osi 31 v osni smeri preprečujeta omejilni steni 19. Med omejilno steno 19 in vertikalnim utorom 36 je umeščen utor 39 in to na obeh straneh osi 31, v katerih sta nameščena kraka vzmeti 33, ki sta v stalnem kontaktu z osjo 31 kolesa 25 in na os 31 pritiskata vertikalno navzdol, to je v smeri proti tlem. Omenjeni utor 39 vodi vzmet 33 tako, da je ta v stalnem kontaktu z osjo 31 in preprečuje snemanje vzmeti 33 z osi 31. Vzmet 33 je naslonjena na ohišje 15 na obeh koncih, to je krakih pa je naslonjena na os 31. Med krakoma vzmeti 33, ki slonita na osi 31 in ohišjem 15 je vzmet 33 vpeta v zaskočni zob 27, ki definira silo vzmeti 33, s katero pritiska na os 31 v njeni določeni vertikalni legi,-3 The housing 15 is preferably of circular cross-section with a cylindrical attachment in the middle for attaching the housing 15 to the carrier axis on the body of the vacuum cleaner 3. On one side of the housing 15, its jacket and part of the bottom are open in the approximate size of the wheel 25. This opening is fenced to form two vertical ones. grooves 36, which guide the axles 31 of the wheel 25 and determine the free vertical movement of the axis 31 and the wheels 25 towards the body of the vacuum cleaner 3. The movement of the axis 31 in the axial direction is prevented by the bounding wall 19. A groove 39 is inserted between the bounding wall 19 and the vertical groove 36, on either side of the axle 31, in which the arms of the spring 33 are mounted, which are in constant contact with the axle 31 of the wheel 25, and press the axis 31 vertically downwards, i.e. in the direction of the ground. Said groove 39 guides the spring 33 in such a way that it is in constant contact with the axis 31 and prevents the spring 33 from being removed from the axis 31. The spring 33 is resting on the housing 15 at both ends, that is, the arms are resting on the axis 31. Between the arms of the spring 33, which rest on the axis 31 and the housing 15, the spring 33 is clamped into the snap tooth 27, which defines the force of the spring 33, by which it presses the axis 31 in its defined vertical position,

Uporaba vrtljivega ohišja z vzmeteno vpetim kolesom 5 omogočajo premik, to je posedanje posameznega kolesa 25 proti telesu sesalne naprave zaradi vpliva obremenitve, ki se pojavi pri neravnih tleh, ko zaradi neravnine hoče kolo 25 lebdeti v zraku. V tem primeru mora kolo 25, ki je v kontaktu z osnovno površinotlemi 11 prenesti večjo obremenitev s sesalnika za prah, kot če obremenitev prenašata obe kolesi 25. Sam sistem je zasnovan tako, da se enakomerno porazdeli masa sesalnika za prah 3 na obe kolesi 25, pri čemer so obe kolesi 25 v stalnem kontaktu s podlago. Pri tem se ne pojavljajo stranski učinki, kot so hrup, saj je prevzemanje teže na vrtljivo kolo blaženo z vzmetjo. Sama sesalna naprava tudi ne zaniha in ne povzroča občutka nestabilnosti.The use of a rotatable housing with a spring-mounted wheel 5 makes it possible to move, that is, to sit the individual wheel 25 against the body of the suction device due to the load effect that occurs on uneven floors when the wheel 25 wants to hover in the air. In this case, the wheel 25 in contact with the base surface 11 must withstand a greater load from the dust vacuum cleaner than if the load is carried by both wheels 25. The system itself is designed to evenly distribute the mass of the dust vacuum cleaner 3 to both wheels 25 , with both wheels 25 in constant contact with the ground. There are no side effects such as noise as the weight on the swivel wheel is dampened by the spring. The suction device itself does not oscillate and does not cause instability.
