Abstract

A household oven door hinge is made of a casing (1), in which there is a beaky holder (4) with a cam (13), bearing-supported pivotably by a pin (3), and then there is a pair of cutouts (5) and a cutout (8) made on the casing (1), where the beaky holder (4) is pivotably attached close to its bearing support to the pin (3) via another pin (30) and a two-prong link (9) to a spring (10) which is attached at the other end to the casing (1) via a pin (11). The characteristic of the hinge is that in the casing (1), namely in cutouts (5), there is a bearing-supported pin (14) which is axially immovably fixed in the cutouts (5) but at the same time freely movable in their longitudinal direction, and on which there is a freely pivotably bearing-supported roller (15) which is narrower than the pin (14) and can roll freely over the cam (13) of the beaky holder (4) during its turning while opening and closing the oven's door. The pin (14) and thus the roller (15) are pushed onto the cam (13) of the beaky holder (4) by an element (16) which is guided within the casing (1) in the longitudinal direction and comprises two springs (17) attached at their opposite ends to a pair of turn-ups (7) in the casing (1).

Description

Tečaj vrat gospodinjske pečiceHinge door hinge

Predmet izumaThe subject of the invention

Predmet izuma je tečaj vrat gospodinjske pečice z vmesno lego priprtih vrat med popolnoma zaprtimi oziroma odprtimi vrati, kar je zaželeno pri nekaterih toplotnih obdelavah hrane.The object of the invention is a hinge door hinge with an intermediate position of the door closed between fully closed or open doors, which is desirable for some food heat treatments.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je, kako zasnovati konstrukcijo tovrstnega tečaja tako, da bo omogočala enostavno, hitro in za delavca varno sestavo tečaja, pri čemer bo konstrukcija zagotavljala tudi enake uporabnostne lastnosti v vsej predvideni življenjski dobi tečaja oziroma vrat pečice kot celote, ki je določena s številom odpiranj, pripiranj in zapiranj vrat, pri katerem ne sme priti do uporabnostnih sprememb oziroma poslabšanj.The technical problem solved by the invention is how to design the design of such a hinge so as to allow easy, quick and safe assembly of the hinge for the worker, and the construction will also provide the same useful properties throughout the life expectancy of the hinge or oven door as a whole, which is determined by the number of door openings, closures and closures, which must not result in usability changes or deterioration.

Znano stanje tehnikeThe prior art

Znan je slovenski patent s skrajšanim trajanjem SI 9600318 (Blues d.o.o.), katerega ena od značilnosti, ki se je pokazala pomanjkljiva, je v tem, da je natezna vijačna vzmet, ki je nameščena na prečnem sorniku stremena, ki je zasukljivo uležajen v kljunastem držalu vrat. Izkazalo se je, da taka povezava dovoljuje neosno delovanje vzmeti na držalo vrat in s tem hitrejšo obrabo giblijih delov. Druga pomanjkljivost, ki skrajšuje življenjsko dobo, pa je izvedba dodatneA Slovenian patent with a shortened duration SI 9600318 (Blues doo) is known, one of the features that has been shown to be defective is that it is a tensile screw spring mounted on a transverse bolt pivotally mounted in a beak holder neck. It turns out that such a connection allows for a non-axial action of the spring on the door holder and thus faster wear of the bible parts. Another drawback that shortens the life span is the implementation of an additional one

32379.doc/VIII-05/D-36-Vr vijačne vzmeti, ki pritiska z enim krakom na kotalno površino valjčka, ki je predviden za kotalenje po grebenu kljunastega držala vrat za določanje vmesnega oziroma priprtega stanja vrat. Izkazalo se je, da je potrebni pritisk vzmeti z enim krakom na valjček tolikšen, da hkrati zavira ali celo ustavi kotalenje valjčka, s čimer pride do drsenja valjčka po grebenu kljunastega držala vrat in s tem do njegove pospešene obrabe, kar skrajšuje predvideno življenjsko dobo tečaja in s tem pečice kot celote.32379.doc / VIII-05 / D-36-Door spring press, which presses with one arm on the rolling surface of the roller, which is intended for rolling down the ridge of the beak door holder to determine the intermediate or closed position of the door. It turns out that the necessary pressure of a spring with one arm on the roller is such that it simultaneously inhibits or even stops the rolling of the roller, thereby sliding the roller along the ridge of the beak door holder and thereby accelerating its wear, which shortens the intended life of the hinge and hence the oven as a whole.

Razen tega sta navedeni konstrukcijski pomanjkljivosti tudi vzrok za sorazmerno zahtevno sestavljanje tečaja. Delavec mora biti ves čas sestavljanja zelo pozoren, da ne pride do sproženja delno vstavljene vzmeti. Razen tega taka konstrukcija ne omogoča cenovno upravičene uvedbe vsaj delne hitrejše strojne montaže.In addition, the aforementioned structural defects are also the reason for the relatively difficult assembly of the hinge. During assembly, the worker must be very careful not to trigger the partially inserted spring. Moreover, such construction does not allow for the introduction of at least partially faster machine assembly at a cost-effective level.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z izvedbo po izumu tako, da je v znani osnovni konstrukciji tečaja izvedeno kljunasto držalo vrat s širokim, prednostno dvokrakim uležajenjem na somik, s čimer je omogočeno tudi razmaknjeno dvojno uležajenje veznega elementa med kljunastim držalom vrat in glavno vzmetjo. S tem je zagotovljena stalna in samo enoosna obremenitev zasukljivih delov v tečaju zaradi delovanja napenjalne vzmeti, kar zagotavlja samo predvideno obrabo v vsej življenjski dobi tečaja.The described technical problem is solved by the embodiment according to the invention, so that in the known basic design of the hinge, a beak door holder with a wide, preferably two-way, self-locking arrangement is provided, which also enables the double bearing of the coupling element to be spaced between the beak door holder and the main spring. This ensures constant and uniaxial loading of the rotating parts in the hinge due to the action of the tension spring, which ensures only intended wear throughout the life of the hinge.

Rešitev drugega problema, navedenega pri SI 9600318 pa je v tem, daje valjček, ki teče po grebenu kljunastega držala, ožji glede na ohišje in sicer toliko, da je prosti somik na vsaki strani valjčka podprt z elementom, ki je vpet v dve vzmeti, ki ga pritiskata na greben kljunastega držala tako, da se valjček kljub pritiskanju na greben prosto kotali po grebenu kljunastega. S tem je odpravljena pretirana obraba valjčka, kot je opisana kot pomanjkljivost pri navedenem patentu s skrajšanim trajanjem.The solution to the second problem mentioned in SI 9600318 is that the roller running down the ridge of the beak holder is narrower relative to the housing, so that the free catfish on each side of the roller is supported by an element that is fixed in two springs, which are pressed against the ridge of the beak holder so that the roller, despite being pressed on the ridge, can roll freely down the ridge of the beak. This eliminates excessive roller wear as described as a drawback of said patent with a shortened duration.

Podrobneje bo bistvo izuma pojasnjeno v nadaljevanju z opisom izvedbenega primera in priložene risbe, na katerih kaže sl. 1 tečaj vrat gospodinjske pečice v čelnem pogledu, sl. 2 isto v stranskem pogledu; in sl. 2 isto v prerezu po črti II-II sl. 1The essence of the invention will be explained in more detail below with a description of an embodiment and the accompanying drawings, in which FIG. 1 is a front view of a door of a household oven, FIG. 2 the same in lateral view; and FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1

Tečaj vrat gospodinjske pečice je izveden iz ohišja 1, kije izvedeno kot U profil s poljubnimi znanimi pritrdišči 2, npr. izvrtinami ali jezički na ohišje pečice, ki ni prikazana na slikah, pri čemer je na enem koncu ohišja 1 zasukljivo na sorniku 3 uležajeno kljunasto držalo 4 vrat pečice, ki tudi niso prikazana na sliki. Na bočnih pasovih ohišja 1 sta nadalje izvedena še dva para izsekov in sicer izseka 5 v obliki podolgovatih lukenj, katerih funkcija bo opisana kasneje, ter izseka 6 z zavihkoma 7 kot prislonoma, kar bo tudi podrobneje pojasnjeno kasneje. V ohišju 1 je nadalje izveden izsek 8, ki dovoljuje sukanje kljunastega držala 4 za približno pravi kot, oziroma kolikor je potrebno, da se odpirajo vrata pečice.The hinge door hinge is made of a housing 1, which is made as a U profile with any known anchorages 2, e.g. bores or tabs to the oven housing not shown in the figures, with a beak-like holder 4 on one end of the housing 1 on the bolt 3 a beak-like holder 4 of the oven door not also shown in the illustration. The lateral bands of the housing 1 further comprise two pairs of sections, section 5 in the form of elongated holes, the function of which will be described later, and section 6 with tabs 7 as a snap, which will be explained in more detail later. The housing 1 is further provided with a section 8 which allows the beak holder 4 to rotate about the right angle, or as long as necessary to open the oven door.

Kljunasto držalo 4 je v bližini svojega uležajenja v somik 3 zasukljivo vpeto v sorniku 30 preko dvokrakega veznika 9 na vzmet 10, ki je na drugem koncu vpeta preko sornika 11 v ohišje 1 in sicer v zeva 12. Vzmet 10 je v dvokrakem vezniku 9 nameščena v izvrtini 91, medtem ko s svojim kavljastim koncem 101 objema somik 11. Somik 11 je v zevu 12 samo vložen, napeta vzmet 10 pa preprečuje izpad sornika 11 iz zeva 12.The beak retainer 4 is rotatably fastened in the bolt 3 in its proximity to its bearing 3 via a double pin 9 to the spring 10, which is secured at the other end via a bolt 11 to the housing 1 and into the yoke 12. The spring 10 is mounted in the two-pointed link 9 in the hole 91, while with its hook end 101 it grips the socket 11. The socket 11 is only inserted in the socket 12, and the taut spring 10 prevents the bolt 11 from falling out of the socket 12.

Kljunasto držalo 4 je izvedeno kot črka L, pri čemer je na konveksni strani stika obeh krakov izvedena grba 13, ki potuje med odpiranjem oziroma zapiranjem vrat skozi izsek 8 ohišja 1 in ki fiksira v določenem kotu priprta vrata. V ohišju 1 je v izsekih 5, izvedenih v smislu podolgovatih lukenj, uležajen somik 14, ki jeThe beak retainer 4 is formed as the letter L, whereby on the convex side of the contact of the two arms is provided a hump 13 which travels during opening or closing of the door through a section 8 of the housing 1 and which fixes the door closed at a certain angle. In the housing 1, in the sections 5 made in the sense of the elongated holes, a catcher 14 is mounted, which is

32379.doc/VI I l-05/D-36-Vr osno nepomično fiksiran v navedenih izsekih 5 in hkrati prosto pomičen v njuni vzdolžni smeri. Na somiku 14 je prosto vrtljivo uležajen valjček 15, kije ožji od somika 14 in se prosto kotali po grbi 13 kljunastega držala 4 med njegovim sukanjem pri odpiranju in zapiranju vrat pečice.32379.doc / VI I l-05 / D-36-Vr axially fixed in the said sections 5 and freely movable in their longitudinal direction. On the fly 14 there is a freely rotating roller 15, which is narrower than the fly 14 and rolls freely on the hump 13 of the beak holder 4 during its rotation when opening and closing the oven door.

V ohišju 1 je nad izsekom 8 za grbo 13 izveden par že navedenih zavihkov 7 v katerih je vpet element 16 za izvajanje sile na grbo 13 za držanje vrat v priprti legi. Element 16 je izveden kot ohišje, v katerem sta osno vzporedno uležajeni dve vzmeti 17 , ki sta oprti na zavihka 7. Element 16 je oblikovan tako, da je zaradi svoje kvadraste oblike osno voden v ohišju 1 in je hkrati vodilo za valjček 15, ki je uležajen v somiku 14. Element 16 nalega na somik 14 ob straneh in hkrati omogoča prosto vrtenje valjčka 15 po grbi 13 kljunastega držala 4 brez drsenja, kar je bila ena od nalog izuma.In the housing 1, a pair of already mentioned tabs 7 are arranged above the section 8 for the coat of arms 13 in which a member 16 is applied to exert a force on the coat of arms 13 for holding the door in the closed position. The element 16 is designed as a housing in which two springs 17, which are supported on the tab 7, are axially parallel. The element 16 is shaped so that, due to its square shape, it is axially guided in the housing 1 and is at the same time a guide for the roller 15, which It is mounted in the catcher 14. The element 16 rests on the catcher 14 on the sides and at the same time allows the roller 15 to rotate freely on the hump 13 of the beak holder 4 without sliding, which was one of the objects of the invention.

Kjunasto držalo 4 je izvedeno v območju somika 3 z razširitvijo 41, v prednostni izvedbi v smislu dvokrakega dela, da je zagotovljena večja trdnosti na morebitne bočne sile, ki lahko nastopijo pri odpiranju in zapiranju vrat. V prednostni izvedbi je zato tudi uležajenje dvokrakega veznika 9 v kljunsto držalo 4 s pomočjo somika 30 izvedeno v območju razširitve 41.The curtain holder 4 is made in the area of the extension 3 with extension 41, preferably in the form of a two-piece, to provide greater strength to any lateral forces that may occur when opening and closing the door. In a preferred embodiment, therefore, the mounting of the two-pointed binder 9 in the bead holder 4 by means of a som 30 is made in the expansion area 41.

Z rešitvijo po izumu, kot je opisana zgoraj, je zagotovljena tudi enostavna montaža, saj je vstavljanje delov v ohišje preprosto in samo pri vstavljanju elementa 16 s parom vzmeti 17 podvržen pozornosti zaradi sile vzmeti 17, pri čemer pa ležišče vzmeti - zavihka 7 zagotavlja, da ne more priti do izskoka vzmeti 17 med montažo ali kasneje. Montaža glavne vzmeti 10 je prav tako enostavna, saj jo še nenapeto samo z enim koncem namestimo v izvrtino 91, nato vstavimo v drugi kavljast konec 101 somik 11, ki ga ob napenjanju vzmeti 10 vskočimo v zev 12. Opisana montaža je bistveno hitrejša in zahteva manj delovneThe solution according to the invention, as described above, also provides for easy installation, since insertion of parts into the housing is easy and only when inserting the element 16 with a pair of springs 17 is subjected to attention due to the force of the spring 17, while the bearing of the spring - tab 7 ensures that to prevent spring 17 from popping up during mounting or later. Installation of the main spring 10 is also easy, since it is only inserted one end into the bore 91 with one end, then inserted into the second hook end 101 of the catfish 11, which, when the spring 10 is tensioned, is jumped into the yoke 12. The described installation is much faster and requires less working
