Abstract

The invention deals with a door hinge of a refrigerator or integrated cooking appliance including a profiled enclosure (1) with lock (2), rotating on a pin (6), which is on its end partly attached to the shaped enclosure (1). Above the rotating point of the lock (6), slightly to the left by distance (a), there is a double tumbler (11) hinged on a pin (7), which is on its upper part linked to the lower plug (5), which holds one side of the extension spring (3). The same spring is by its other end suspended on the upper plug (4), which is by its extremes partly attached to the upper part of the enclosure (1). Above the lock (2) ridge (2a) there is a rotating wheel (10) on the pin (9), moving parallel and guided by longitudinal cut-out openings (12) between the tumblers (14), where this wheel is on one side subjected to the lower end (11a) of the torsion spring (11), applied to the linking pin (8). In the locked position of the oven doors, the torsion spring (11) by its lower end (11a) exerts pressure on wheel (10), while the wheel (10) exerts pressure on the steep lateral side beneath the lock (2) ridge (2a) thus acting with a certain force against the support (17). The main force, which makes the oven doors move into the closed position is produced by the lever resulting from the force of the extension spring (3) around the rotating point of the pin (6).

Tečaj za vrata štedilnika ali vgradnega kuhalnega aparataDoor hinge for cooker or built-in cooker

Predstoječi izum se nanaša na izboljšave na tečaju, ki se uporablja za vrata štedilnika ali vrata vgradnega kuhalnega aparata.The present invention relates to improvements to the hinge used for cooker doors or built-in cooker doors.

Predmet izuma je uvrščen v razred E05F 1/12 mednarodne klasifikacije patentov.The subject matter of the invention is classified in class E05F 1/12 of the International Patent Classification.

Tečaji uvodoma navedene vrste so v splošnem poznani. Iz nemške patentne GM7833577 je poznan tečaj s takoimenovano sabljo, ki je namenjena za pozicijoniranje vrat štedilnika. Slabost tovrstnega tečaja je njegova glasnost, ki jo povzroči kotaljenje kolesa po robu sablje, poleg tega pa je tečaj zgrajen iz sorazmerno velikega števila sestavnih delov in je zato večja možnost, da se pokvari.The courses of the species mentioned above are generally known. From German patent GM7833577 is known a hinged saber hinge designed to position the stove door. The disadvantage of this type of hinge is its volume caused by the rolling of the wheel along the edge of the saber, and the hinge is constructed of a relatively large number of components and is therefore more likely to break.

Naloga predstoječe iznajdbe je torej tečaje uvodoma navedene vrste tako izpopolniti, da bodo odpravljene uvodoma navedene pomanjkljivosti. Zastavljena naloga je rešena z izvedbo tečaja s profiliranim ohišjem, iz katerega štrli zapah, ki je v spodnjem delu vrtljivo vležajen na sorniku, obojestransko vpetem v profilirano ohišje . Nad sornikom zapaha nekoliko v levo, je skozi zapah vrtljivo vležajen sornik, na konceh katerega sta nasajeni dvojni stremeni, ki sta na vrhu povezani s čepom, ki je z vsakim od svojih koncev gibljiv v vzdolžno izsekanih luknjah profiliranega ohišja tečaja. Na sredino čepa , ki je s svojima koncema vzporedno gibljiv v vzdolžno izsekanih luknjah stremen, je obešena natezna vzmet, ki je s svojim drugim koncem obešena za gornji čep, ki je s skrajnima koncema fiksiran v gornjem delu profiliranega ohišja tečaja. Nad grebenom zapaha je na sorniku, vertikalno gibljivem in vodenim, v vzdolžno izsekanih luknjah obeh stremen nataknjeno kolo, na katerega z enim krakom pritiska torzijska vzmet. S svojim drugim krakom je ista torzijska vzmet, ki je nataknjena na čep med stremenoma zapeta v jeziček na enem izmed stremen. Pri zaprtih vratih en krak torzijske vzmeti pritiska na kolešček, ta pa ob strmino grebena zapaha in s tem povzroči delovanje sile na zaprta vrata pečice.The object of the present invention is therefore to refine the courses of the type mentioned above in such a way that the disadvantages described above will be eliminated. This task is solved by the implementation of a hinge with a profiled housing, from which a latch protrudes, which is pivotally mounted on the bolt in the lower part, mounted on both sides of the profiled housing. Above the bolt bolt slightly to the left, a bolt is pivotally inserted through the bolt, at the ends of which are mounted double stirrups, which are connected at the top by a pin, which is movable at each of its ends in longitudinally cut holes of the profiled hinge housing. A tensile spring is suspended at the center of the stud, which is parallel to its ends in parallel with the longitudinally cut holes of the stirrups, and its other end is suspended by an upper stud fixed at the upper ends of the profiled hinge housing. Above the ridge of the latch, a wheel is mounted on a bolt, vertically movable and guided, in the longitudinally cut holes of the two stirrups, with a torsion spring pressed with one arm. With its second arm, the same torsion spring that is attached to the stud between the stirrups is clamped into a tab on one of the stirrups. With the door closed, one arm of the torsion spring presses against the roller, which on the slope of the ridge lifts, causing force to exert on the closed door of the oven.

Med odpiranjem vrat pečice se kolešček preko grebena zapaha skotali na drugo stran grebena zapaha, kjer lahko zadrži štedilniška vrata v priprti legi za določen kot. V priprti legi vrat je sila, s katero torzijska vzmet pritiska na kolo, skupaj s težo vrat večja od sile, ki jo povzroči natezna zmet, ki sili kolo preko vrha grebena in s tem tudi vrata v zaprto lego.While opening the oven door, the roller rolls over the ridge latch to the other side of the latch, where it can hold the stove door in the closed position for a certain angle. In the closed door position, the force exerted by the torsion spring on the wheel, together with the weight of the door, is greater than the force exerted by the tensile spring which forces the wheel over the top of the ridge and thus the door into the closed position.

Above the bolt (6) slightly to the left, a bolt (7) is rotated through the latch (2), at the ends of which are mounted double stirrups (14) connected at the top by a lower pin (5) connected to each of its ends movable in longitudinally cut holes (15) of the profiled housing (1) of the hinge. In the middle of the lower pin (5), which is parallel to its ends, movable in the longitudinally cut holes (15) of the profiled casing (1), a tensile spring (3) is suspended, suspended by its other end by the upper pin (4). which is fixed at the extremities in the upper part of the profiled housing (1) of the hinge. Above the ridge (2a) of the latch (2), there is a connecting pin (8) between the stirrups (14) to which a torsion spring (11) is attached, the upper arm (11b) of which is stuck into the tab (13) of one of the stirrups (14). ). The lower arm (11a) of the torsion spring (11) is supported by a roller (10) which rotates on the bolt (9). The latch (2b) of the latch (2) allows the latch (2) to be united uniquely in the saddle latch (16) and not extend too deeply into the housing of the bracket (17).
