Abstract

Izum samonastavljiva noga rešuje problem zibanja pohištva in vseh naprav ali aparatov, ki imajo tri ali več nog. Problem nastane zaradi neravnih talnih površin tako v prostoru kot v naravi. Poleg stabilnosti pa tudi omogoča postavitev delovnih površin naprav ali aparatov v popolnoma vodoraven položaj ali pa v zaželeni naklon s tem da je zagotovljena popolna stabilnost naprave. Samonastavljiva noga je sestavljena iz votlega jedra (1), zunanjega plašča (4), ki je premičen v vertikalni smeri in pa zaskočke(6), ki je pritrjena na plašč (4).Na jedru (1) je eno ali več vodil (A,B,C in D) in zobata letev (3), ki omogočajo gibanje zatiča (6) v smeri od A,B,C do D, ne pa v obratni smeri. Zaskočka (6) se zaradi vzmeti (11) zatakne v zobato letev (3). Naloga vzmeti (2) v jedru (1) je da je jedro (1) prilagodi podlagi. Zaskočka (6) ima enega ali več zobčenikov (13) in s tem omogoča večjo nosilnost oziroma uporabo različnih vrst materialov (plastika, kovina). Napravo uporabimo tako, da najprej položimo na tla desnostran naprave ali aparata in nato levo stran ali pa obratno, tako da pridejo vse zaskočke v začetni položaj , to je do točke A. Z dvigom naprave ali aparata pa nato nastavimo v zaželeni položaj, to je vodoravni ali postrani. Napravo lahko višamo vse do višine ko zaskočka (6) na eni izmed nog naprave ne pride v vodilu do točke D, ko noga izgubi nosilnost. V tem primeru moramo napravo zopet nastaviti v začetni položaj.The invention of a self-adjusting foot solves the problem of rocking furniture and all devices or appliances having three or more legs. The problem is caused by uneven floor surfaces both in space and in nature. In addition to its stability, it also allows the installation of work surfaces of devices or appliances to be fully horizontal or in a desirable slope, in order to ensure complete stability of the device. The self-adjusting leg consists of a hollow core (1), an outer jacket (4) movable in the vertical direction and a latch (6) attached to the jacket (4). On the core (1) there is one or more guides ( A, B, C, and D) and toothed racks (3) which allow the pivot (6) to move in the direction from A, B, C to D, but not in the reverse direction. The latch (6) is stuck to the toothed rack (3) due to the spring (11). The function of the springs (2) in the core (1) is that the core (1) is adapted to the basis. The latch (6) has one or more lugs (13), thus allowing greater load capacity or use of different types of materials (plastic, metal). Use the device first by placing the right device or appliance on the floor, then the left side or vice versa, so that all the locks arrive at the starting position, that is to the point A. By lifting the device or apparatus, then the device is set to the desired position, that is, horizontal or sideways. The device can be raised up to the height when the latch (6) on one of the legs does not enter the guide to the point D when the foot loses its load. In this case, the device must be reset to its initial position.

Description

SAMONASTAVLI IVA NOGASELF-ADJUSTED IVA FOOT

Predmet izuma je naprava , ki omogoča vsem aparatom ali pohištvu s tremi ali več nogami stabilno vodoravno ali poševno nastavitev na neravni podlagi.The subject of the invention is a device that allows all appliances or furniture with three or more legs a stable horizontal or oblique adjustment on an uneven surface.

Tehnični problem, ki se pojavlja pri postavitvi naprav, aparatov (npr. pralni stroj) ali pohištva (npr. mize), je nestabilnost zaradi neravne talne površine. Npr. gostinci imajo probleme z mizami na zunanjih površinah, ali pa postavitev žara pri kampiranju, postavitev lestve na gradbišču, itd...A technical problem that arises when placing appliances, appliances (e.g. washing machine) or furniture (e.g. tables) is instability due to uneven floor surface. Eg. caterers have problems with tables on outdoor surfaces, or setting up a barbecue when camping, setting up a ladder on a construction site, etc ...

Ene izmed dosedaj znanih rešitev je ročna izravnava naprave s pomočjo vijaka in matice. Ob premiku pohištva (npr. mize) ali aparatov je ponastavljanje naprave dokaj zahtevno. Naslednji patenti uporabljajo vijačni sistem za reševanje problema:One of the solutions known so far is the manual leveling of the device with the help of a screw and nut. When moving furniture (eg tables) or appliances, resetting the device is quite difficult. The following patents use a screw system to solve the problem:

- US 7,267,309 iz leta 2007 (baza ZDA USPTO)- US 7,267,309 from 2007 (USPTO database)

- US 6,142, 431 iz leta 2000 (baza ZDA USPTO)- US 6,142, 431 in 2000 (USPTO database)

- US020060091269A iz leta 2006 (baza Nemčije DEPATISnet)- US020060091269A from 2006 (German database DEPATISnet)

Druge rešitve uporabijo vzmetni sistem. Ta je po uporabi podoben vijačnim sistemom. Nastavitev višine je treba ročno nastavljati, kar se izkaže za precej zamudno:Other solutions use a spring system. This is similar to a screw system after use. The height adjustment has to be adjusted manually, which turns out to be quite time consuming:

-US 5,042,764 iz leta 1991(baza ZDA USPTO)-US 5,042,764 1991 (USPTO US Base)

-US8888850427694A iz leta 1991 (baza Nemčije DEPATISnet)-US8888850427694A from 1991 (German database DEPATISnet)

-DE202005007317U1 iz leta 2010 (baza Nemčije DEPATISnet)-DE202005007317U1 from 2010 (German database DEPATISnet)

Nekatere rešitve vklučujejo sistem hidravlike. Hidravlični aparati na vseh nogah morajo biti med sabo še fluidno povezani. Npr. miza se res sama postavi v vodoraven položaj, a rešitev je relativno predraga za masovno proizvodnjo. Recimo ,Some solutions include a hydraulic system. The hydraulic devices on all legs must be fluidly connected to each other. Eg. the table does set itself up in a horizontal position, but the solution is relatively too expensive for mass production. Let's say

Naslednji izumitelj seje lotil reševanja problema z netrdimim materiali, ki se prilagodijo in omogočijo stik s podlago, tako da ni tresenja:The following inventor of the session set out to solve the problem with non-hard materials that adapt and allow contact with the substrate so that there is no shaking:

Izum samonastavljiva noga vsebuje naslednje elemente:The invention self-adjusting leg contains the following elements:

- notranji valj, ki mu bomo rekli jedro 1- the inner cylinder, which we will call the core 1

- zobata letev 3toothed rack 3

- zunanji valj, ki se premika po jedru gor/dol in mu bomo rekli plašč 4- an outer cylinder that moves up / down the core and will be called a jacket 4

- zaskočka, ki opravlja tudi funkcijo vodila 6- a latch which also performs the function of a guide 6

- spiralna vzmet 2coil spring 2

Jedro 1 ima obliko votlega valja, ki je na spodnjem delu zaprt 7. Na jedru 1 je urezan eden ali več utorov (A,B,C,D ), ki služi kot vodilo za usmerjeno gibanje plašča 4 . V vsakem utorjo je vrajena zobata letev ( A , B ) . Zaskočka 6,ki je pritrjena na plašč 4,v zato pripravljeno mesto 5, omogoča gibanje plašča na valju samo v smeri od začetne točke A po zobati letvi do B , ne pa obratno. Pri gibanju plašča od točke B do točke C se plašč zarotira, ko se zaskočka pelje po vodilu. Gibanje od C preko D do A je neovirano. Prav tako se plašč na valju zarotira, ko gre od D do A. Vhodni utor E ima samo funkcijo združitve jedra z plaščem.The core 1 has the shape of a hollow cylinder, which is closed at the lower part 7. One or more grooves (A, B, C, D) are cut on the core 1, which serves as a guide for the directional movement of the jacket 4. A toothed rack (A, B) is returned in each groove. The latch 6, which is attached to the jacket 4, in the specially prepared position 5, allows the movement of the jacket on the cylinder only in the direction from the starting point A along the toothed rack to B, and not vice versa. When the tire moves from point B to point C, the tire rotates as the latch travels along the guide. Movement from C through D to A is unhindered. Also, the jacket on the cylinder rotates when it goes from D to A. The input groove E only has the function of merging the core with the jacket.

Na valju je lahko vgrajena ena ali več zobatih letev 3, odvisno od števila utorov (na sliki 1, sliki 2, je valj z dvema zobatima letvima). Z eno zobato letvijo je lahko dosežemo določeno natančnost višine noge, kar je odvisno od razdalje med zobčeniki. Tako z dvema zobatima letvima natančnost prilagoditve noge na podlago podvojimo, z štirimi zobatimi letvami pa lahko natančnost početverimo. Pri tem je treba zobate letve na valj vgraditi na različnih višinah po formuli razdalje med dvema zobcema 13 in delimo z številom vgrajenih zobatih letev 3. Z večjo natančnostjo samonastavljive noge dosežemo večjo stabilnost naprave.One or more toothed racks 3 can be installed on the cylinder, depending on the number of grooves (in Figure 1, Figure 2, there is a cylinder with two toothed racks). With one toothed rack it is possible to achieve a certain accuracy of leg height, which depends on the distance between the gears. Thus, with two toothed slats, the accuracy of adjusting the foot to the base is doubled, and with four toothed slats, the accuracy can be quadrupled. In this case, the toothed racks on the cylinder must be installed at different heights according to the formula for the distance between two teeth 13 and divided by the number of installed toothed racks 3. With greater accuracy of the self-adjusting foot, greater stability of the device is achieved.

Zobata letev 3 ima zobčenike 13,slika 6, oblikovane tako, da je kot večji od 90° glede na podlago zobate letve. Drugače povedano, zobci so rahlo obrnjeni v smer gibanja zaskočke 6 . S tem doseženo da teža naprave potisne zaskočko v stabilen prileg in je pri tem potrebna minimalna sila vzmeti 11, ki potiska zaskočko na zobato letev 3.The toothed rack 3 has gears 13, Fig. 6, designed to have an angle greater than 90 ° with respect to the base of the toothed rack. In other words, the teeth are slightly turned in the direction of movement of the latch 6. In this way, the weight of the device pushes the latch into a stable fit and a minimum spring force 11 is required, which pushes the latch onto the rack 3.

Plašč 4 noge ima obliko votlega valja , ki je na zgornji strani zaprt 8,na katero je pripeto tudi vodilo 9 za vzmet 2 . Ob strani ima odprtine 5, kamor se vgradi zaskočka 6. Na plašču sta v tem primeru vgrajeni dve zaskočki. Zaskočka je sestavljena iz premičnega dela 10 in ohišja 12 . Vzmet 11 potiska premični del zaskočke 10 v zobato letev 3. Oblika zobčenikov na zobati letvi in zaskočki onemogoča gibanje zaskočke po letvi na dol, od B do A. Druga naloga zaskočke je prenos teže naprave na jedro noge. Vzmet v jedru noge 2 pa potiska jedro noge na dol, dokler noga ne obremeni podlago. Tako dosežemo, da so vse noge naprave v stiku s podlago. Stabilnost naprave je dosežena, ker teža naprave pritiska zaskočko v »zaklenjen« položaj noge.The jacket 4 of the leg has the shape of a hollow cylinder, which is closed on the upper side 8, to which a guide 9 for the spring 2 is also attached. It has openings 5 on the side, where the latch 6 is installed. In this case, two latches are installed on the jacket. The latch consists of a movable part 10 and a housing 12. The spring 11 pushes the movable part of the latch 10 into the rack 3. The shape of the gears on the rack and latches prevents the latch from moving down the bar, from B to A. Another function of the latch is to transfer the weight of the device to the core of the foot. The spring in the core of the foot 2 pushes the core of the foot downwards until the foot loads the ground. This ensures that all the legs of the device are in contact with the ground. The stability of the device is achieved because the weight of the device presses the latch into the "locked" position of the foot.

Zaskočka 6 ima lahko različno število zobcev, ki so zrcalna slika zobcev na zobati letvi 3. Zaskočko z več zobci omogoča uporaba različni materialov. Jedro noge je lahko narejeno iz kovine ali plastike . Zaskočka ima tudi funkcija vodila 14, ki omogoča gibanje plašča na jedru od točke A,B, C in D nazaj v začetni položaj A .The latch 6 can have a different number of teeth, which are a mirror image of the teeth on the rack 3. The latch with several teeth allows the use of different materials. The core of the leg can be made of metal or plastic. The latch also has a guide function 14, which allows the movement of the jacket on the core from point A, B, C and D back to the initial position A.

Spiralna vzmet 2 se uporabja za krajše dolžine nogic in ima tudi funkcijo razbremeniteve zaskočke 6,vendar vse noge neejo imeti večje nosilnosti od teže naprave. Za naprave kjer je potrebno premositi večjo višinsko razliko med nogami (npr. lestve ) pa lahko uporabimo tudi plinski amortizer.The coil spring 2 is used for shorter leg lengths and also has the function of a relief latch 6, but not all legs have a higher load capacity than the weight of the device. For devices where it is necessary to bridge a larger height difference between the legs (eg ladders), we can also use a gas shock absorber.
