OBLAST PRONALASKA FIELD OF INVENTION

[0001] Predmetni pronalazak se odnosi na uređaj remenice za klizna vrata, iz oblasti hardverskog pribora za arhitektonsku dekoraciju. [0001] The present invention relates to a pulley device for sliding doors, from the field of hardware accessories for architectural decoration.

STANЈE TEHNIKE PRONALASKA STATE OF THE ART OF THE INVENTION

[0002] Trenutno se klizna vrata široko koriste u industriji vrata za zgrade zahvaljujući lakoći ugradnje i praktičnosti upotrebe. U normalnom slučaju, gornji krajevi i donji krajevi kliznih vrata opremljeni su remenicama koje se podudaraju sa odgovarajućim gornjim i donjim šinama, tako da korisnik može pogodno gurnuti i povući klizna vrata. BR MU9002588U2 stavlja na uvid javnosti konstrukcioni raspored u kliznom uređaju za klizna vrata koji olakšava aktiviranje opruga protiv iskliznuća i podešavanje vrata kroz ekscentričnu osovinu, koji obuhvata spoljašnje kućište koje ima unutrašnju površinu predviđenu sa parom linearnih vođica postavljenih paralelno sa gornjom ortogonalnom izbočinom sa diskontinuiranim centralnim regionom, od ortogonalne izbočine koja se pruža nadole par izduženih konstrukcija paralelnih sa linearnim vođicama i razmaknutih od unutrašnje strane kućišta spolja. [0002] Currently, sliding doors are widely used in the building door industry thanks to the ease of installation and practicality of use. In the normal case, the upper ends and lower ends of the sliding door are equipped with pulleys that match the corresponding upper and lower rails, so that the user can conveniently push and pull the sliding door. BR MU9002588U2 discloses to the public a structural arrangement in a sliding device for a sliding door that facilitates actuation of anti-slip springs and door adjustment through an eccentric shaft, comprising an outer housing having an inner surface provided with a pair of linear guides positioned parallel to an upper orthogonal projection with a discontinuous central region, from the orthogonal projection extending downwardly a pair of elongate structures parallel to the linear guides and spaced from the inside of the case to the outside.

[0003] U stanju tehnike, CN201320016707.2 stavlja na uvid javnosti uređaje remenice postavljene na vrhu ili dnu kliznih vrata. Kao što je prikazano na sl. 1a i sl.1b, kosa kružna rupa 02 nadole je postavljena na prednjoj fasadi donje ploče, a krstasti zavrtanj 03 je postavljen u kosoj kružnoj rupi 02. Kada je pokretna stranica vrata 04 neravna, krstasti zavrtanj 03 može da se okreće odvijačem 05, tako da se remenica 01 podiže ili spušta, visina kliznih vrata podešava. Kao što je prikazano na sl. 1b, kada su remenice 01 ugrađene na klizna vrata 04, sklop ima nekoliko nedostataka navedenih u daljem tekstu: (1) Pošto se kosa kružna rupa 02 instalirana sa krstastim zavrtanjem 03 nalazi na prednjoj fasadi donje ploče, remenica 01 se može instalirati samo u ugrađenom tipu, dok se ne može realizovati instalacija tipa lopatica, a instalaciju tipa lopatica je potrebno dodatno projektovati; (2) U praktičnoj upotrebi, bočna strana pokretne stranice vrata 04 montirane sa remenicama 01 često se postavlja sa fiokom i sličnim elementima, između njih ostaje mali razmak. Dakle, kada se koristi odvijač 05 kako bi se podesila visina krstastog zavrtnja 03, odvijač 05 teško prodire iz razmaka u kosu kružnu rupu 02, tako da se podešavanje ne može izvršiti. [0003] In the state of the art, CN201320016707.2 discloses to the public pulley devices placed on top or bottom of sliding doors. As shown in fig. 1a and Fig.1b, the inclined circular hole 02 is placed downward on the front facade of the bottom plate, and the cross screw 03 is placed in the oblique circular hole 02. When the moving side of the door 04 is uneven, the cross screw 03 can be rotated with a screwdriver 05, so that the pulley 01 is raised or lowered, the height of the sliding door is adjusted. As shown in fig. 1b, when the pulley 01 is installed on the sliding door 04, the assembly has several disadvantages listed below: (1) Since the oblique circular hole 02 installed with the cross screw 03 is located on the front facade of the bottom plate, the pulley 01 can only be installed in the built-in type, while the paddle type installation cannot be realized, and the paddle type installation needs to be additionally designed; (2) In practical use, the side of the movable side of the door 04 mounted with pulleys 01 is often placed with a drawer and similar elements, leaving a small gap between them. Therefore, when the screwdriver 05 is used to adjust the height of the cross screw 03, the screwdriver 05 hardly penetrates from the gap into the oblique circular hole 02, so that the adjustment cannot be made.

[0004] U stanju tehnike, uređaj remenice koji se može ugraditi na uspravan i obrnuti način je stavljen na uvid javnosti u CN201710642591.6. Kao što je prikazano na sl. 2: mehanizam za podešavanje visine uključuje maticu 2 za podešavanje i zavrtanj 1 za podešavanje koji se može podići ili spustiti kada se matica 2 za podešavanje rotira, a rupa 8 za podešavanje prodire kroz kutiju 3-2 a donja ploča 3-1 je obezbeđena u kućištu 3. U stanju sklapanja, kraj zavrtnja 1 za podešavanje naslanja se na kliznu ploču, a matica 2 za podešavanje je barem delimično uvučena u rupu 8 za podešavanje. Stanje tehnike koje je gore pomenuto ima sledeće nedostatke: (1) Pošto je rupa 8 za podešavanje izložena, a okruženje za postavljanje je uglavnom u kući, lako se može desiti da se malo kose ili vune ubaci u rupu 8 za podešavanje, koja se obavija oko zavrtnja 1 za podešavanje, što utiče na njegov rad i vek trajanja. (2) Zavrtanj 1 za podešavanje služi kao unutrašnje podešavanje, a navoj zavrtnja 1 za podešavanje će trpeti većinu sile. Zbog toga se navoj zavrtnja 1 za podešavanje lako ošteti i klizna nit nastaje nakon višestrukog sudara kontaktne klizne ploče. Zbog toga je poželjno dobiti izdržljive i stabilne remenice, koje se mogu ugraditi na gornje ili donje krajeve kliznih vrata u instalaciju tipa lopatica ili ugradnu instalaciju. [0004] In the state of the art, a pulley device that can be installed in an upright and inverted manner is disclosed to the public in CN201710642591.6. As shown in fig. 2: the height adjustment mechanism includes an adjustment nut 2 and an adjustment screw 1 that can be raised or lowered when the adjustment nut 2 is rotated, and the adjustment hole 8 penetrates the box 3-2 and the bottom plate 3-1 is provided in the case 3. In the folded state, the end of the adjustment screw 1 rests on the sliding plate, and the adjustment nut 2 is at least partially inserted into the adjustment hole 8. The above-mentioned prior art has the following disadvantages: (1) Since the adjustment hole 8 is exposed, and the installation environment is mostly indoors, it is easy for some hair or wool to be inserted into the adjustment hole 8, which wraps around the adjustment screw 1, affecting its operation and service life. (2) Adjusting screw 1 serves as an internal adjustment, and the thread of adjusting screw 1 will bear most of the force. Therefore, the thread of the adjustment screw 1 is easily damaged and the sliding thread is formed after the contact sliding plate collides multiple times. Therefore, it is desirable to obtain durable and stable pulleys, which can be installed on the upper or lower ends of the sliding door in a paddle-type installation or a built-in installation.

KRATAK OPIS PRONALASKA BRIEF DESCRIPTION OF THE INVENTION

[0005] Cilj predmetnog pronalaska je da se prevaziđe nedostatak da samo jedan tip uređaja remenice može da realizuje instalaciju tipa lopatice ili ugradnu instalaciju, nedostatak da se visina remenice ne može pogodno podešavati i da se remenice iz stanja tehnike lako mogu oštetiti, niske pouzdanosti i kratkog veka trajanja. [0005] The aim of the present invention is to overcome the disadvantage that only one type of pulley device can realize a blade-type installation or a built-in installation, the disadvantage that the height of the pulley cannot be conveniently adjusted and that the state-of-the-art pulleys can be easily damaged, have low reliability and have a short lifespan.

[0006] Da bi se postigao cilj, obezbeđen je uređaj remenice, koji sadrži kućište remenice; kliznu ploču koja je vertikalno pokretna i postavljena na kućište remenice; remenicu postavljenu na kliznu ploču; mehanizam za podešavanje visine, za podešavanje visine remenice; i amortizer koji povezuje kliznu ploču i kućište remenice. Mehanizam za podešavanje visine sadrži prvu izbočinu i drugu izbočinu koja može da se poklapa sa prvom izbočinom, i prva izbočina se nalazi na jednom kraju klizne ploče, a druga izbočina je montirana na kućište remenice i može se okretati, a visina remenice se može podesiti kada je prva izbočina nasuprot različitim položajima druge izbočine. Mehanizam za podešavanje visine dalje sadrži blok za pričvršćivanje montiran na kućište remenice, i sklop za podešavanje koji pokreće rotaciju druge izbočine, a sklop za podešavanje prodire kroz blok za pričvršćivanje. Sklop za podešavanje sadrži prednju polugu za podešavanje i zadnju polugu za podešavanje montiranu na prednjoj poluzi za podešavanje, a rupe za podešavanje su obezbeđene i na prednjoj poluzi za podešavanje i na zadnjoj poluzi za podešavanje. Sklop za podešavanje dalje sadrži element protiv padanja i priključnu osovinicu, blok za pričvršćivanje je opremljen žlebom u koji je postavljen element protiv padanja, a priključna osovinica prolazi kroz središnji otvor druge izbočine. [0006] To achieve the goal, a pulley device is provided, which includes a pulley housing; a sliding plate that is vertically movable and mounted on the pulley housing; a pulley mounted on a sliding plate; mechanism for adjusting the height, for adjusting the height of the pulley; and a shock absorber connecting the slide plate and the pulley housing. The height adjustment mechanism includes a first protrusion and a second protrusion that can coincide with the first protrusion, and the first protrusion is located at one end of the sliding plate, and the second protrusion is mounted on the pulley housing and can be rotated, and the height of the pulley can be adjusted when the first protrusion is opposite to different positions of the second protrusion. The height adjustment mechanism further comprises an attachment block mounted on the pulley housing, and an adjustment assembly that drives the rotation of the second projection, and the adjustment assembly penetrates the attachment block. The adjustment assembly includes a front adjustment lever and a rear adjustment lever mounted on the front adjustment lever, and adjustment holes are provided on both the front adjustment lever and the rear adjustment lever. The adjustment assembly further comprises an anti-drop element and a connecting pin, the attachment block is provided with a groove in which the anti-drop element is placed, and the connecting pin passes through the center hole of the second projection.

[0007] Predmetni pronalazak obezbeđuje mehanizam za podešavanje visine koji može da podesi visinu uređaja remenice i pri uspravnom i obrnutom postavljanju (ugradnja tipa lopatica ili ugradna instalacija), u kom slučaju je ispupčenje rezervisano za mehanizam za podešavanje visine i amortizer (posebno, ukupna debljina uređaja remenice se poklapa sa mehanizmom za podešavanje visine i amortizerom, posebno, remenica prihvata i mehanizam za podešavanje visine i amortizer, tako da je debljina remenice konzistentna pa nema razlike između uspravnih postavljanja i obrnutog postavljanja). U slučaju ugradne pozicije, uređaj remenice može biti i izbočen iz tela kliznih vrata i ugrađen u telo kliznih vrata. Štaviše, to olakšava inženjeru da odabere način ugradnje gornjeg i donjeg uređaja remenice na klizna vrata. Instalacija tipa lopatica i ugradna instalacija imaju svoje prednosti i nedostatke, tim redosledom. Pogodnija je instalacija tipa lopatice, koja se može instalirati bez unapred urađenih instalacionih utora. Ugrađena instalacija ugrađuje uređaj remenice u žleb prisutan na telu vrata. Prostor uređaja remenice koji viri iz tela vrata je smanjen, a telo vrata koje izgleda kao celina je estetski privlačnije. U tehničkom rešenju predmetnog pronalaska, postavljač može da kupi jedan uređaj remenice i da izabere bilo koji način ugradnje prema želji korisnika. [0007] The present invention provides a height adjustment mechanism that can adjust the height of the pulley device in both upright and inverted installation (blade-type installation or built-in installation), in which case the protrusion is reserved for the height adjustment mechanism and the shock absorber (in particular, the total thickness of the pulley device matches the height adjustment mechanism and the shock absorber, in particular, the pulley accepts both the height adjustment mechanism and the shock absorber, so that the thickness of the pulley is consistent and there is no difference between the upright placement and reverse placement). In the case of the built-in position, the pulley device can be both protruding from the body of the sliding door and embedded in the body of the sliding door. Moreover, it makes it easier for the engineer to choose the way to install the upper and lower pulley device on the sliding door. Vane-type installation and flush-mounted installation have their advantages and disadvantages, in that order. A blade-type installation is more convenient, which can be installed without pre-made installation grooves. The built-in installation installs the pulley device in the groove present on the door body. The space of the pulley device protruding from the door body is reduced, and the door body, which looks like a whole, is more aesthetically appealing. In the technical solution of the subject invention, the installer can purchase one pulley device and choose any method of installation according to the user's wishes.

[0008] Pogodno je da se druga izbočina ’ugnezdi’ na sklopu za podešavanje. Spoljna kontura druge izbočine ima postepeno rastući poluprečnik, a druga izbočina stoji naspram prve izbočine na jednom kraju klizne ploče. Rastojanje od spoljne konture druge izbočine do sklopa za podešavanje može se podesiti rotiranjem sklopa za podešavanje. Mehanizam za podešavanje visine je dodatno opremljen poklopcem za pričvršćivanje bloka za pričvršćivanje, a poklopac je pričvršćen na gornjoj površini kućišta remenice. Druga izbočina je u obliku brega, a spoljna kontura druge izbočine je opremljena zupčanikom. Druga izbočina je opremljena ispupčenjem koje ograničava položaj na oba kraja spoljne konture na drugoj izbočini. Rastojanje za podešavanje se održava tako da se ruta ispupčenja koje ograničava položaj ne menja kružno i da se udaljenost podešavanja može stabilno kontrolisati. Rupe za podešavanje predviđene i na prednjoj poluzi za podešavanje i na zadnjoj poluzi za podešavanje su uglavnom izabrane kao šestougaone priključnice. [0008] It is convenient for the second projection to 'nest' on the adjustment assembly. The outer contour of the second protrusion has a gradually increasing radius, and the second protrusion abuts the first protrusion at one end of the sliding plate. The distance from the outer contour of the second projection to the adjustment assembly can be adjusted by rotating the adjustment assembly. The height adjustment mechanism is additionally equipped with a cover for fixing the fixing block, and the cover is fixed on the upper surface of the pulley housing. The second protrusion is in the form of a cam, and the outer contour of the second protrusion is equipped with a gear. The second protrusion is provided with a protrusion that limits the position at both ends of the outer contour on the second protrusion. The adjustment distance is maintained so that the route of the position limiting protrusion does not change circularly and the adjustment distance can be stably controlled. The adjustment holes provided on both the front adjustment lever and the rear adjustment lever are generally selected as hexagonal sockets.

[0009] Predmetni pronalazak ima dodatne prednosti. Da bi rotirao drugu izbočinu u obliku brega, postavljač može da okrene prednju polugu za podešavanje ili zadnju polugu za podešavanje tako što će umetnuti šestougaoni odvijač u šestougaonu priključnicu i rotirati rukom. Na ovaj način se može podesiti visina uređaja remenice. U predmetnom pronalasku, neće se pojaviti problem da je razmak između kliznih vrata i nameštaja premali da bi se podesila visina uređaja remenice pomoću odvijača, koji se pojavljuje u stanju tehnike. Kao rezultat toga, mehanizam za podešavanje visine uređaja remenice nije ograničen uskim prostorom i u velikoj meri olakšava postavljaču da podesi visinu uređaja remenice. Štaviše, neće se pojaviti problem da nakon što se uređaj remenice podesi pomoću matice za podešavanje i zavrtnja za podešavanje, uređaj remenice nije dostupan ili oštećen zbog toga što je neka kosa ili vuna umetnuta u rupu za podešavanje. Tako se može poboljšati pouzdanost rada i radni vek uređaja remenice. [0009] The subject invention has additional advantages. To rotate the second cam protrusion, the setter can turn the front adjustment lever or the rear adjustment lever by inserting a hex driver into the hex socket and rotating by hand. In this way, the height of the pulley device can be adjusted. In the present invention, there will be no problem that the distance between the sliding door and the furniture is too small to adjust the height of the pulley device with a screwdriver, which appears in the prior art. As a result, the mechanism for adjusting the height of the pulley device is not limited by the narrow space and greatly facilitates the setter to adjust the height of the pulley device. Furthermore, there will not be a problem that after the pulley device is adjusted with the adjusting nut and the adjusting screw, the pulley device is not accessible or damaged due to some hair or wool being inserted into the adjusting hole. Thus, the operational reliability and service life of the pulley device can be improved.

[0010] Još jedna bolja shema je da blok za pričvršćivanje ima rotirajuću rupu za rotaciju prednje poluge za podešavanje; prva izbočina je nagnuta, i prva izbočina je usklađena sa zupčanikom na spoljnoj konturi druge izbočine. Pošto je prva izbočina usklađena sa zupčanikom na spoljnoj konturi druge izbočine, sili će biti izložen blok za pričvršćivanje. Blok za pričvršćivanje ima dovoljnu površinu, tako da se neće deformisati i oštetiti. Na ovaj način se može izbeći problem oštećenja navoja matice za podešavanje. Štaviše, zgodno je i lako podesiti rastojanje druge izbočine pomoću šestougaonog odvijača kako bi se postiglo podizanje ili spuštanje uređaja remenice. [0010] Another better scheme is that the attachment block has a rotating hole for rotating the front adjustment lever; the first protrusion is inclined, and the first protrusion is aligned with a gear on the outer contour of the second protrusion. Since the first protrusion is aligned with the gear on the outer contour of the second protrusion, the clamping block will be subjected to force. The fixing block has sufficient surface area, so it will not be deformed and damaged. In this way, the problem of damage to the threads of the adjusting nut can be avoided. Moreover, it is convenient and easy to adjust the distance of the second protrusion with a hex screwdriver to achieve the raising or lowering of the pulley device.

[0011] Još jedna bolja shema je da se spojni kraj zadnje poluge za podešavanje povezuje sa zadnjom polugom za podešavanje. Prednja poluga za podešavanje i zadnja poluga za podešavanje su integrisane kako bi se olakšala ugradnja i poboljšana je pouzdanost proizvoda. [0011] Another better scheme is that the connecting end of the rear adjustment lever connects to the rear adjustment lever. The front adjustment lever and the rear adjustment lever are integrated to facilitate installation and improve the reliability of the product.

[0012] Još jedna bolja shema je da je klizna ploča vertikalno pokretna, a da se remenica montirana na kliznu ploču može rotirati. Na taj način, zbog podudaranja između remenice i šine, remenica u šini omogućava kliznim vratima da se nesmetano kreću po šini. [0012] Another better scheme is that the sliding plate is vertically movable, and that the pulley mounted on the sliding plate can be rotated. In this way, due to the match between the pulley and the rail, the pulley in the rail allows the sliding door to move smoothly on the rail.

[0013] Još jedna bolja shema je da je amortizer opruga sa jednim krajem koji se oslanja na kliznu ploču, a drugim krajem se oslanja na kućište remenice. Opruga obezbeđuje remenici silu koja se prenosi na šinu, čineći da remenica glatko radi na šini. [0013] Another better scheme is that the shock absorber is a spring with one end resting on the sliding plate and the other end resting on the pulley housing. The spring provides the pulley with a force that is transmitted to the rail, making the pulley run smoothly on the rail.

[0014] Još jedna shema je da je remenica povezana sa kliznom pločom pomoću zakivka koji može da se okreće, a remenica delimično viri iz klizne ploče. Pogodno je otvoriti ili zatvoriti vrata klizanjem preko remenica koje se kotrljaju po šinama na gornjem i donjem kraju vrata. Klizna ploča uključuje ploču i izbočinu koja viri iz ploče. Izbočina je opremljena rupom za prislanjenje, a jedan kraj opruge je ugrađen u rupu za prislanjenje. Ovakvim prislanjanjem, opruga se može efikasno stisnuti između kućišta remenice i klizne ploče, što naglašava saradnju opruge sa kliznom pločom, a donosi korist jer sila opruge olakšava kotrljanje remenice postavljene na kliznu ploču. [0014] Another scheme is that the pulley is connected to the sliding plate by means of a rivet that can rotate, and the pulley partially protrudes from the sliding plate. It is convenient to open or close the door by sliding over the pulleys that roll on the rails at the upper and lower ends of the door. The slide plate includes a plate and a protrusion protruding from the plate. The protrusion is equipped with a bearing hole, and one end of the spring is installed in the bearing hole. By this abutment, the spring can be effectively compressed between the pulley housing and the sliding plate, which emphasizes the cooperation of the spring with the sliding plate, and brings benefits because the spring force facilitates the rolling of the pulley mounted on the sliding plate.

[0015] Još jedna bolja shema je da je klizna ploča opremljena žlebom za ograničavanje položaja koji je u zahvatu sa blokom za ograničavanje položaja na kućištu remenice. Prilikom ugradnje, remenica se podiže na minimalno rastojanje od tela vrata i postavlja na šinu, zatim se otpušta blok za ograničavanje položaja, a zatim se podešavaju prednja poluga za podešavanje i zadnja poluga za podešavanje. Na ovaj način se može postići funkcija blokiranja remenice na minimalnom rastojanju. Ova konstrukcija je pogodna za ugradnju i izbegava problem da je ugradnja blokirana zbog toga što je razmak između remenice i šine premali za rukovanje. [0015] Another better scheme is that the sliding plate is equipped with a groove for limiting the position that engages with the block for limiting the position on the pulley housing. When installing, the pulley is raised to the minimum distance from the door body and placed on the rail, then the position limit block is released, and then the front adjustment lever and rear adjustment lever are adjusted. In this way, the function of blocking the pulley at a minimum distance can be achieved. This design is convenient for installation and avoids the problem of the installation being blocked due to the gap between the pulley and the rail being too small to handle.

[0016] Predmetni pronalazak obezbeđuje pokretna vrata koja sadrže uređaj remenice i šinu koja se koristi za pomeranje uređaja remenice i tela vrata, a šina se nalazi iznad ili ispod tela vrata. [0016] The present invention provides a movable door that contains a pulley device and a rail used to move the pulley device and the door body, and the rail is located above or below the door body.

[0017] Uređaj remenice sadrži kućište remenice, kliznu ploču koja je vertikalno pokretna i montirana na kućište remenice, remenicu montiranu na kliznu ploču, mehanizam za podešavanje visine, za podešavanje visine remenice, i amortizer koji povezuje kliznu ploču i kućište remenice. [0017] The pulley device contains a pulley housing, a sliding plate that is vertically movable and mounted on the pulley housing, a pulley mounted on the sliding plate, a height adjustment mechanism, for adjusting the height of the pulley, and a shock absorber that connects the sliding plate and the pulley housing.

[0018] Mehanizam za podešavanje visine sadrži prvu izbočinu i drugu izbočinu koja može da odgovara prvoj izbočini, pri čemu je prva izbočina postavljena na kliznoj ploči, a drugi izbočina je montirana na kućištu remenice i može da se okreće, a visina remenice može da se podesiti kada prva izbočina stoji nasuprot različitim pozicijama druge izbočine. Mehanizam za podešavanje visine dalje sadrži blok za pričvršćivanje montiran na kućište remenice i sklop za podešavanje koji pokreće rotaciju druge izbočine, a sklop za podešavanje prodire kroz blok za pričvršćivanje. Druga izbočina stoji naspram prve izbočine na jednom kraju klizne ploče. Rastojanje od spoljne konture druge izbočine do sklopa za podešavanje može se podesiti rotacijom sklopa za podešavanje. Mehanizam za podešavanje visine je dodatno opremljen poklopcem za pričvršćivanje bloka za pričvršćivanje, a poklopac je pričvršćen na gornjoj površini kućišta remenice. Druga izbočina je u obliku brega, a spoljna kontura druge izbočine je opremljena zupčanikom. Ispupčenja koja ograničavaju položaj su raspoređena na svakoj krivini čvora na oba kraja spoljašnje konture na drugoj izbočini. Sklop za podešavanje sadrži prednju polugu za podešavanje i zadnju polugu za podešavanje montirane na prednju polugu za podešavanje, a šestougaone rupe su obezbeđene i na prednjoj poluzi za podešavanje i zadnjoj poluzi za podešavanje. [0018] The height adjustment mechanism includes a first protrusion and a second protrusion that can correspond to the first protrusion, wherein the first protrusion is mounted on the sliding plate, and the second protrusion is mounted on the pulley housing and can be rotated, and the height of the pulley can be adjusted when the first protrusion is opposite to different positions of the second protrusion.

DETALJAN OPIS PRIKAZANIH TEHNIČKIH REŠENJA DETAILED DESCRIPTION OF THE SHOWN TECHNICAL SOLUTIONS

[0021] Predmetni pronalazak će dalje biti detaljno opisan u nastavku teksta uz upućivanje na priložene slike nacrta i specifična tehnička rešenja. Sledeći primeri su namenjeni da ilustruju pronalazak, ali nisu namenjeni da ograniče obim pronalaska. [0021] The subject invention will be further described in detail in the following text with reference to the attached drawings and specific technical solutions. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

[0022] Tehničko rešenje remenice prema predmetnom pronalasku je prikazano pomoću uređaja remenice koji je postavljen na donjem kraju kliznih vrata. Kao što je prikazano na sl. 3 do sl. 8, uređaj remenice obuhvata kućište 1 remenice, i kliznu ploču 2-3 koja je montirana na kućište 1 remenice i može se pomerati gore i dole, i mehanizam 3 za podešavanje visine da bi se podešavala visina klizne ploče 2- 3, i amortizer 4 koji spaja kliznu ploču 2-3 i kućište 1 remenice. Kućište 1 remenice uključuje donju ploču 1-1 i šupljinu 1-2 za montažu klizne ploče na donjoj ploči 1-1. Šupljina 1-2 za montažu viri iz kućišta 1 remenice i može da primi kliznu ploču 2-3 tako da se može postići i instalacija tipa lopatica ili ugradna instalacija. [0022] The technical solution of the pulley according to the present invention is shown by means of a pulley device which is placed at the lower end of the sliding door. As shown in fig. 3 to fig. 8, the pulley device includes a pulley housing 1, and a sliding plate 2-3 that is mounted on the pulley housing 1 and can be moved up and down, and a height adjustment mechanism 3 to adjust the height of the sliding plate 2-3, and a shock absorber 4 that connects the sliding plate 2-3 and the pulley housing 1. The pulley housing 1 includes a bottom plate 1-1 and a cavity 1-2 for mounting the sliding plate on the bottom plate 1-1. The mounting cavity 1-2 protrudes from the pulley housing 1 and can receive the sliding plate 2-3 so that either a paddle-type installation or a flush-mounted installation can be achieved.

[0023] Konkretno, režim ugradnje je prisutan na sledeći način. Kod ugradnje tipa lopatica, donja ploča 1-1 pričvršćuje se zavrtnjima na telo vrata kliznih vrata, a šupljina 1-2 za montažu viri iz tela vrata. U međuvremenu, visina uređaja remenice se može podesiti sa jedne strane donje ploče 1-1, koja je udaljena od šupljine 1-2 za montažu, preko mehanizma 3 za podešavanje visine. Kod ugradne instalacije, šupljina 1-2 za montažu je ugrađena u unapred postavljen žleb na vratima, a vrata su pričvršćena za donju ploču 1-1 sa stranom blizu šupljine 1-2 za montažu. U međuvremenu, visina remenice se može podesiti sa strane donje ploče 1-1, koja nije pričvršćena za vrata, preko mehanizma 3 za podešavanje visine. Postavljač može kupiti uređaj remenice i izabrati bilo koji način ugradnje prema želji korisnika. [0023] Specifically, the installation mode is present as follows. When installing the vane type, the bottom plate 1-1 is attached to the door body of the sliding door with screws, and the mounting cavity 1-2 protrudes from the door body. Meanwhile, the height of the pulley device can be adjusted from one side of the bottom plate 1-1, which is away from the mounting cavity 1-2, through the height adjustment mechanism 3. In flush installation, the mounting cavity 1-2 is installed in the pre-set groove of the door, and the door is attached to the bottom plate 1-1 with the side close to the mounting cavity 1-2. Meanwhile, the height of the pulley can be adjusted from the side of the bottom plate 1-1, which is not attached to the door, through the height adjustment mechanism 3. The installer can purchase the pulley device and choose any installation method according to the user's wishes.

[0024] U nekim tehničkim rešenjima, kućište 1 remenice je komad ploče sa neispunjenom šupljinom koja obuhvata kliznu ploču 2-3, mehanizam 3 za podešavanje visine i amortizer 4. Međutim, kućište 1 remenice i mehanizam 3 za podešavanje visine rade nezavisno i ne ometaju jedno drugo. Kućište 1 remenice se ugrađuje na telo vrata bez potrebe za razlikovanjem uspravne ili obrnute ugradnje. [0024] In some technical solutions, the pulley housing 1 is a piece of plate with an unfilled cavity that includes the sliding plate 2-3, the height adjustment mechanism 3 and the shock absorber 4. However, the pulley housing 1 and the height adjustment mechanism 3 work independently and do not interfere with each other. The housing 1 of the pulley is installed on the body of the door without the need to distinguish between upright or inverted installation.

[0025] Specifična situacija podešavanja je prisutna na sledeći način. Mehanizam 3 za podešavanje visine je opremljen blokom 3-1 za pričvršćivanje ugrađenim u kućište 1 remenice, i sklopom za podešavanje koji prodire kroz blok 3-1 za pričvršćivanje, i drugom izbočinom 3-2 postavljenom na sklop za podešavanje. Sklop za podešavanje uključuje prednju polugu 3-6 za podešavanje i zadnju polugu 3-7 za podešavanje montiranu na prednju polugu 3-6 za podešavanje. Spoljna kontura druge izbočine 3-2 ima postepeno povećanje poluprečnika i stoji naspram prve izbočine 2-1 na jednom kraju klizne ploče 2-3. Rastojanje od spoljne konture druge izbočine 3-2 do sklopa za podešavanje može se fleksibilno podesiti rotiranjem sklopa za podešavanje. Tada se može izvršiti podešavanje visine klizne ploče 2-3. Mehanizam za podešavanje visine je opremljen poklopcem 3-3 za fiksiranje bloka 3-1 za pričvršćivanje umetnutog unutar šupljine 1-2 za montažu. Poklopac 3-3 je pričvršćen na gornjoj površini kućišta 1 remenice. Poklopac 3-3 je pričvršćen maticom u žlebu spoljašnje površine šupljine 1-2 za montažu tako da je poklopac 3-3 horizontalno identičan spoljašnjoj površini šupljine 1-2 za montažu. Mehanizam 3 za podešavanje visine postaje konstrukcija skrivenog tipa, tako da vuna ili kosa neće ući u unutrašnjost mehanizma 3 za podešavanje visine i uzrokovati ometanje podešavanja. Druga izbočina 3-2 je u obliku brega, a spoljna kontura druge izbočine 3-2 je opremljena zupčanikom 3-4. Zupčanik 3-4 sarađuje sa prvom izbočinom 2-1 u radnom stanju, a mehanizam 3 za podešavanje visine ne pomera čak ni veći broj odskakanja klizne ploče 2-3. Ispupčenja 3-5 koja ograničavaju položaj su postavljena na svakoj krivulji čvora oba talasasto zupčasta kraja spoljašnje konture na drugoj izbočini 3-2. Rastojanje za podešavanje se održava tako da se ruta ispupčenja 3-5 koje ograničava položaj ne menja kružno (okreće se manje i više napred-nazad) i da se podešavanje rastojanja može stabilno kontrolisati. I na prednjoj poluzi 3-6 za podešavanje i na zadnjoj poluzi 3-7 za podešavanje postoje šestougaone rupe koje pripadaju sklopu za podešavanje. [0025] A specific setting situation is present as follows. The height adjustment mechanism 3 is equipped with a fixing block 3-1 built into the pulley housing 1, and an adjustment assembly penetrating through the fixing block 3-1, and another projection 3-2 mounted on the adjustment assembly. The adjustment assembly includes a front 3-6 adjustment lever and a rear 3-7 adjustment lever mounted on the front 3-6 adjustment lever. The outer contour of the second protrusion 3-2 has a gradual increase in radius and stands against the first protrusion 2-1 at one end of the sliding plate 2-3. The distance from the outer contour of the second projection 3-2 to the adjustment assembly can be flexibly adjusted by rotating the adjustment assembly. The height of the sliding plate 2-3 can then be adjusted. The height adjustment mechanism is equipped with a cover 3-3 for fixing the block 3-1 for fastening inserted inside the mounting cavity 1-2. The cover 3-3 is fixed on the upper surface of the housing 1 of the pulley. The cover 3-3 is fixed with a nut in the groove of the outer surface of the mounting cavity 1-2 so that the cover 3-3 is horizontally identical to the outer surface of the mounting cavity 1-2. The height adjustment mechanism 3 becomes a hidden type construction, so that wool or hair will not enter the interior of the height adjustment mechanism 3 and cause the adjustment to be disturbed. The second protrusion 3-2 is cam-shaped, and the outer contour of the second protrusion 3-2 is equipped with a gear 3-4. The gear 3-4 cooperates with the first protrusion 2-1 in the working condition, and the height adjustment mechanism 3 does not move even the higher number of bounces of the sliding plate 2-3. Protrusions 3-5 which limit the position are placed on each curve of the node of both wave-toothed ends of the outer contour on the second projection 3-2. The adjustment distance is maintained so that the route of the position-limiting protrusion 3-5 does not change circularly (turns back and forth less and more) and the distance adjustment can be stably controlled. Both the front 3-6 adjustment lever and the rear 3-7 adjustment lever have hex holes that belong to the adjustment assembly.

[0026] Treba napomenuti da druga izbočina 3-2 mehanizma 3 za podešavanje visine remenice predmetnog pronalaska nije ograničena na oblik brega, i da je oblik sa postepeno povećavajućim radijusom (kao što je krivi štap, ekscentrični točak, torziona šipka, itd.) u okviru obima zaštite predmetnog pronalaska. Da bi rotirao drugu izbočinu 3-2 u obliku brega, postavljač može da rotira prednju polugu 3-6 za podešavanje ili zadnju polugu 3-7 za podešavanje tako što će ručno ubaciti šestougaoni odvijač u šestougaonu priključnicu. Na ovaj način se može podesiti visina uređaja remenice. I neće doći do problema da je rastojanje između kliznih vrata i okova premalo da bi se pomoću odvijača podesila visina uređaja remenice. Kao rezultat toga, mehanizam 3 za podešavanje visine uređaja remenice nije ograničen uskim prostorom, i u velikoj meri olakšava postavljaču da podesi visinu uređaja remenice. Štaviše, neće se pojaviti problem da nakon što se uređaj remenice podesi pomoću matice za podešavanje i zavrtnja za podešavanje, uređaj remenice nije dostupan ili oštećen zbog toga što je neka kosa ili vuna umetnuta u otvor za podešavanje. Tako se može poboljšati pouzdanost rada i radni vek uređaja remenice. [0026] It should be noted that the second protrusion 3-2 of the pulley height adjustment mechanism 3 of the present invention is not limited to a cam shape, and that a shape with a gradually increasing radius (such as a crooked rod, an eccentric wheel, a torsion bar, etc.) is within the scope of protection of the present invention. To rotate the second cam-shaped projection 3-2, the setter can rotate the front adjustment lever 3-6 or the rear adjustment lever 3-7 by manually inserting a hex driver into the hex socket. In this way, the height of the pulley device can be adjusted. And there will be no problem that the distance between the sliding door and the hardware is too small to adjust the height of the pulley device with a screwdriver. As a result, the mechanism 3 for adjusting the height of the pulley device is not limited by a narrow space, and greatly facilitates the setter to adjust the height of the pulley device. Furthermore, there will not be a problem that after the pulley device is adjusted with the adjusting nut and the adjusting screw, the pulley device is not accessible or damaged due to some hair or wool being inserted into the adjusting hole. Thus, the operational reliability and service life of the pulley device can be improved.

[0027] Blok 3-1 za pričvršćivanje je opremljen rotirajućom rupom za rotaciju prednje poluge 3-6 za podešavanje; prva izbočina 2-1 je nagnuta i prva izbočina 2-1 je usklađena sa zupčanikom 3-4 na spoljnoj konturi druge izbočine 3-2, a nagnuta prva izbočina 2-1 je postavljena suprotno od smera zubaca zupčanika 3-4, tako da se druga izbočina 3-2 neće okretati čak ni u slučaju višestrukih odbijanja. Prva izbočina 2-1 je usklađena sa zupčanikom na spoljnoj konturi druge izbočine 3-2, sila će biti preneta na blok 3-1 za pričvršćivanje. Blok 3-1 za pričvršćivanje ima dovoljnu površinu, tako da se neće deformisati i oštetiti. Na ovaj način se može izbeći problem oštećenja navoja matice za podešavanje. Štaviše, zgodno je i lako podesiti rastojanje druge izbočine pomoću šestougaonog odvijača kako bi se postiglo podizanje ili spuštanje uređaja remenice. Prednja poluga 3-6 za podešavanje obuhvata element 3-6-1 protiv padanja, priključne osovinice 3-6-2 i spojni kraj zadnje poluge 3-7 za podešavanje. Vredi napomenuti da su spojni kraj i zadnja poluga 3-7 za podešavanje integrisani. Element 3-6-1 protiv padanja je postavljen u žleb 3-8 bloka 3-1 za pričvršćivanje. A element 3-6-1 protiv padanja je oblika cilindra i rotira se rotacijom prednje poluge 3-6 za podešavanje. Priključna osovinica 3-6-2 prodire kroz središnji otvor druge izbočina 3-2. Spojni kraj se povezuje sa zadnjom polugom 3-7 za podešavanje. Prednja poluga 3-6 za podešavanje i zadnja poluga 3-7 za podešavanje su integrisane da bi se olakšala ugradnja i poboljšala pouzdanost proizvoda. [0027] The fixing block 3-1 is equipped with a rotating hole for rotating the front lever 3-6 for adjustment; the first protrusion 2-1 is inclined and the first protrusion 2-1 is aligned with the gear 3-4 on the outer contour of the second protrusion 3-2, and the inclined first protrusion 2-1 is set opposite to the direction of the teeth of the gear 3-4, so that the second protrusion 3-2 will not rotate even in the case of multiple rejections. The first protrusion 2-1 is aligned with the gear on the outer contour of the second protrusion 3-2, the force will be transmitted to the block 3-1 for fastening. The attachment block 3-1 has sufficient surface area, so it will not be deformed and damaged. In this way, the problem of damage to the threads of the adjusting nut can be avoided. Moreover, it is convenient and easy to adjust the distance of the second protrusion with a hex screwdriver to achieve the raising or lowering of the pulley device. The front adjustment arm 3-6 includes the anti-drop element 3-6-1, the connecting pins 3-6-2 and the connecting end of the rear adjustment arm 3-7. It is worth noting that the connecting end and the rear 3-7 adjustment lever are integrated. The anti-fall element 3-6-1 is placed in the groove 3-8 of the fixing block 3-1. And the anti-drop element 3-6-1 is cylinder-shaped and rotates by rotating the front adjustment lever 3-6. The connecting pin 3-6-2 penetrates through the central opening of the second projection 3-2. The connecting end connects to the rear lever 3-7 for adjustment. The front 3-6 adjustment lever and the rear 3-7 adjustment lever are integrated to facilitate installation and improve product reliability.

[0028] Klizna ploča 2-3 je vertikalno pokretna, a remenica 2-2 postavljena na kliznu ploču se može rotirati. Pri tome, saradnjom remenice 2-2 sa šinom, remenica 2-2 u šini omogućava kliznim vratima da se nesmetano pomeraju u šini. Amortizer 4 je opremljen oprugom 4-1. Opruga 4-1 se nalazi u šupljini 1-2 za montažu, sa jedanim krajem opruge 4-1 koji naleže na kliznu ploču 2-3, i drugim krajem koji naleže na krajnju ivicu šupljine 1-2 za montažu. Opruga 4-1 obezbeđuje remenici 2-2 silu koja deluje na stazi, čineći da se remenica 2-2 nesmetanije kotrlja u stazi. Remenica 2-2 je spojena sa kliznom pločom 2-3 pomoću zakivka i može se okretati, a remenica 2-2 delimično viri iz klizne ploče 2-3. Pogodno je otvoriti ili zatvoriti vrata klizeći preko remenice 2-2 koja se kotrlja po šini na gornjem i donjem kraju vrata. Klizna ploča 2-3 uključuje ploču i izbočinu koja viri iz ploče. Izbočina je opremljena rupom 2-4 za prislanjanje, a jedan kraj opruge 4-1 je ugrađen u rupu 2-4 za prislanjanje. Ovakvim prislanjenjem, opruga 4-1 se može efikasno stisnuti između šupljine 1-2 za montažu i klizne ploče 2-3, što naglašava saradnju opruge 4-1 i klizne ploče 2-3 i doneti pogodnost da sila opruge olakšava kotrljanje remenice 2-2 montirane na kliznu ploču. Donja ploča 1-1 ima otvor za montažu za pričvršćivanje remenice 2-2 na vrata. [0028] The sliding plate 2-3 is vertically movable, and the pulley 2-2 placed on the sliding plate can be rotated. In addition, by the cooperation of the 2-2 pulley with the rail, the 2-2 pulley in the rail allows the sliding door to move smoothly in the rail. Shock absorber 4 is equipped with spring 4-1. The spring 4-1 is located in the mounting cavity 1-2, with one end of the spring 4-1 resting on the sliding plate 2-3, and the other end resting on the end edge of the mounting cavity 1-2. Spring 4-1 provides pulley 2-2 with a force acting on the track, making pulley 2-2 roll more smoothly in the track. The pulley 2-2 is connected to the slide plate 2-3 by means of a rivet and is rotatable, and the pulley 2-2 partially protrudes from the slide plate 2-3. It is convenient to open or close the door by sliding over the 2-2 pulley that rolls on the rail at the upper and lower end of the door. Slide plate 2-3 includes a plate and a protrusion protruding from the plate. The protrusion is provided with abutment hole 2-4, and one end of the spring 4-1 is fitted into the abutment hole 2-4. By such abutment, the spring 4-1 can be effectively compressed between the mounting cavity 1-2 and the sliding plate 2-3, which emphasizes the cooperation of the spring 4-1 and the sliding plate 2-3 and brings convenience that the spring force facilitates the rolling of the pulley 2-2 mounted on the sliding plate. Bottom plate 1-1 has a mounting hole for attaching pulley 2-2 to the door.

[0029] Klizna ploča 2-3 je opremljena žlebom 2-5 za ograničavanje položaja koji je u zahvatu sa blokom 1-3 za ograničavanje položaja na donjoj ploči 1-1. Prilikom ugradnje, remenica 2-2 se podiže na minimalno rastojanje od kućišta vrata i postavlja na šinu, zatim se otpušta blok 1-3 za ograničavanje položaja, a zatim se podešava prednja poluga 3-6 za podešavanje i zadnja poluga 3-7 za podešavanje. Na ovaj način se može postići funkcija zaključavanja remenice 2-2 na minimalnom rastojanju. Ova konstrukcija je pogodna za ugradnju i izbegava problem da je ugradnja blokirana zbog toga što je rastojanje između remenice i šine premalo za rukovanje. [0029] The sliding plate 2-3 is equipped with a groove 2-5 for limiting the position which is engaged with the block 1-3 for limiting the position on the lower plate 1-1. When installing, the pulley 2-2 is raised to the minimum distance from the door casing and placed on the rail, then the position limiting block 1-3 is released, then the front adjustment lever 3-6 and the rear adjustment lever 3-7 are adjusted. In this way, the 2-2 pulley locking function can be achieved at a minimum distance. This design is convenient for installation and avoids the problem of the installation being blocked due to the distance between the pulley and the rail being too small to handle.
