Zato je cilj izuma prav odpravi te pomanjkljivosti.Therefore, the object of the invention is precisely to remedy these disadvantages.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z novim tesnilom po izumu, katerega bistvena novost je v izvedbi rebra in komplementarnem žlebu ter v razporeditvi bočnih pasov, ki izhajata iz naležnega pasova, povezanega z rebrom in ki se zaključujeta s ploščatim cevastim delom, v katerem je nameščen magnetni trak. Navedena razporeditev bočnih pasov je na obeh straneh žleba zamaknjena stran od njega, s čimer se pri odpiranju pojavi sila , ki deluje pravokotno na bližnjo poševno ploskev rebra v žlebu in s tem onemogoči premik oziroma izvlek tesnila iz žleba tudi pri povečani sli, npr. ob zaledenitvi tesnila na ohišje.The described technical problem is solved by a new gasket according to the invention, the essential novelty of which is in the design of the rib and in the complementary groove and in the arrangement of the lateral belts arising from the contact belt connected to the rib and which terminate with a flat tubular part in which the magnetic is mounted tape. This arrangement of lateral belts is offset on both sides of the gutter, thereby opening a force acting on the adjacent oblique surface of the rib in the gutter, thereby preventing the movement or withdrawal of the gutter from the gutter even in case of increased slippage, e.g. when icing the seal on the housing.

Podrobneje bo bistvo izuma pojasnjeno v nadaljevanju z opisom izvedbenega primera in priložene risbe, na kateri kaže sl. 1 prečni prerez tesnila po izumu, nameščenega v vratih aparata.The essence of the invention will be explained in more detail below with a description of an embodiment and the accompanying drawing, in which FIG. 1 is a cross-sectional view of a seal according to the invention mounted in the door of the apparatus.

Tesnilo 1 vrat hladilnega ali zamrzovalnega aparata s toplotno izoliranim ohišjem 2, ki se zapira z vrati 3, ki so tudi toplotno izolirana in na katerih notranji strani roba 4 je nameščeno v žlebu 5 tesnilo 1, ki je prednostno magnetno. Tesnilo 1 je izvedeno v obliki meha , opremljeno s tesnilno glavo 6 z magnetnim trakom 7 in vznožjem 8, ki sta med seboj povezana z razteznima gubama 9 in 9', pri čemer je pod vznožjem izvedeno rebro 10 opremljeno s poševnima zagozdama 11 in je zasidrano v žlebu 5. Žleb 5 se s svojima bočnima stenama 12 razširja proti svojemu dnu 13, tako da v prednostni izvedbi tvori v preseku oblikoDoor seal 1 of a refrigerator or freezer with a heat-insulated housing 2, which is closed by a door 3, which is also thermally insulated, and on the inside of the edge 4 of which a gasket 1, preferably magnetic, is housed in the groove 5. The seal 1 is made in the form of a bellows, equipped with a sealing head 6 with a magnetic strip 7 and the base 8, which are connected to each other by the expansion folds 9 and 9 ', the rib 10 being provided with oblique wedges 11 and anchored below the base. in the groove 5. The groove 5 extends with its lateral walls 12 towards its bottom 13 so that in the preferred embodiment it forms in cross-section a shape

Na enem stiku vznožja 8 in raztezne gube 9, ki se nahaja na strani roba 4 vrat 3 je prioblikovano pero 15, ki s svojim prostim robom nalega na vrata 3 ob robu 4. Nasprotna guba 9\ ki leži stran od roba 4 vrat 3 pa je izvedena s peresom 16, ki nalega na notranjo ploskev vrat 3. Obe peresi povečujeta tesnost med vrati 3 in ohišjem 2 aparata.At one junction of the base 8 and the extending crease 9, which is located on the side of the edge 4 of the door 3, a feather 15 is formed, which with its free edge rests on the door 3 at the edge 4. The opposite crease 9 \, which lies away from the edge 4 of the door 3, it is made with a pen 16 that rests on the inner surface of door 3. Both pens increase the tightness between door 3 and housing 2 of the apparatus.

Vznožje 8 nalega na odsek vrat 3 ob žlebu 5, da se poveča stabilnost sidranja tesnila 1 s svojim rebrom 10. Guba 9', ki leži stran od roba 4 vrat 3 povezana z vznožjem 8 zamaknjeno od rebra 10 in sicer toliko, da pravokotnica na del 14 bočne stene 12 teče skozi stik gube 9' in vznožja 8. Pri odpiranju vrat ob premagovanju magnetne sile in občasno tudi sile za prekinitev spoja zaradi zaledenitve tesnila na ohišje nastane sila tudi med tesnilom in žlebom. Ker teče stik gube 9' in vznožja 8 na pravokotnici na del 14 bočnih sten 12 in ker se navedena sila pri odpiranju vrat prenaša na gubi 9 in 9' in preko njiju na vznožje 8 in rebro 10, se na delu 14 sten 12 pojavi samo normalna sila brez momenta, ki onemogoča izdrtje rebra 10 iz žleba, kar je namen izuma.The foot 8 rests on the section of door 3 along the groove 5 to increase the stability of the anchorage of the seal 1 with its rib 10. The fold 9 'lying away from the edge 4 of the door 3 connected to the base 8 is offset from the rib 10 so that the perpendicular to part 14 of the side wall 12 runs through the contact of the folds 9 'and the base 8. When the door is opened, magnetic force is interrupted and, occasionally, the force to break the joint due to the icing of the seal on the housing also creates a force between the seal and the groove. Since the contact of the folds 9 'and the sockets 8 on the rectangle to the part 14 of the sidewalls 12, and since the said force, when opening the door, is transmitted to the folds 9 and 9' and through them to the base 8 and the rib 10, only the part 14 of the walls 12 appears a normal torque-free force that prevents the rib 10 from protruding from the groove, which is the purpose of the invention.

Opisana rešitev ni uporabna samo na taki izvedbi vrat 3, kot je prikazana na sl. 1 in sestoje iz zunanje plošče 17 z zavihkom 18, na katerem je nameščena notranja plošča 19 z žlebom 5 za tesnilo 1 po izumu, pri čemer sta plošči 17 in 18 med seboj spojeni z izolacijskim sredstvom 20, ki zapolnjuje votlino vrat, ampak pri kakršnih koli tonamenskih vratih z žlebom za tesnilo.The solution described is not only applicable to port 3 as shown in FIG. 1 and consisting of an outer plate 17 having a tab 18 on which an inner plate 19 is provided with a groove 5 for the seal 1 according to the invention, the plates 17 and 18 being interconnected by an insulating means 20 that fills the cavity of the door, any door with a groove for gasket.
