Abstract

A sliding gate that runs on rollers (7, 8) mounted on two roller blocks anchored in the ground, comprises a box section (1) that has on its lower wall a longitudinal aperture (5) through which the roller blocks (3) project into the interior of the box section (1). The rollers (8) that run on the flat inside upper wall (10) of the box section (1) are cylindrical rollers. The rollers (7) that run on the inside of the lower wall of the box section (1) are groove rollers which engage with ribs of diametrically opposite contour, running in the longitudinal direction of the box section (1) immediately alongside the longitudinal aperture. Without using lateral guide rollers, this design provides precision guidance of the sliding gate when the latter is opened and closed.

Description

Izum se odnosi na slobodno noseća klizna vrata, npr. za ulaze s vratnim krilom produženim preko širine otvora vrata, čiji je donji graničnik kutijasti profil, na kojem je pričvršćen umetak vrata, i taj je pomično uležišten na bočno pokraj vratnog otvora na podu pričvršćeni oslonac valjčića, pri čemu oslonci valjčića strše u unutrašnjost kutijastog profila kroz predviđeni uzdužni raspor na donjem zidu kutijastog profila i svaki oslonac valjčića najmanje jedan par valjčića, koji je prislonjen unutra prema gornjem zidu kutijastog profila, nosi najmanje jedan par valjčića, koji je prislonjen prema donjem zidu kutijastog profila, pri čemu su na unutarnjoj strani donjeg zida predviđena po dva uzdužno postavljena rebra s presjekom uglavnom polukružnog, trokutastog ili kvadratičnog oblika, koji zahvaćaju u valjčiće donjeg para valjčića izrađenih poput valjčića s utorima. The invention relates to free-standing sliding doors, e.g. for entrances with a door leaf extended over the width of the door opening, the lower limit of which is a box profile, on which the door insert is attached, and which is movably placed on a support attached to the floor next to the door opening rollers, whereby the roller supports protrude into the interior of the box profile through the provided longitudinal gap on the lower wall of the box profile and each roller support at least one pair of rollers, which is pressed against the upper wall of the box profile, carries at least one pair of rollers, which is pressed against the lower wall with a box profile, where on the inside of the lower wall there are two longitudinally placed ribs with a section of mostly semi-circular, triangular or square shape, which engage the rollers of the lower pair of rollers made like rollers with grooves.

Takva klizna vrata su poznata iz AT-PS 383 853. Kod tih poznatih kliznih vrata na unutarnjoj strani kutijastog profila, proizvedenog postupkom istiskivanja iz aluminija, predviđena su, ne samo na unutarnjoj strani gornjeg zida nego i na donjem zidu neposredno pokraj uzdužnog raspora kutijastog profila pripadajuća rebra, koja zahvaćaju potpuno u valjčiće izrađene poput valjčića s utorima, tako da su nepotrebni bočni valjčići za vođenje kutijastog profila kliznih vrata, koja su poznata iz AT-PS 357 739 ili ona DE-PS 15 59 958. Such sliding doors are known from AT-PS 383 853. In these known sliding doors, on the inside of the box profile, produced by the aluminum extrusion process, they are provided, not only on the inside of the upper wall, but also on the lower wall directly next to the longitudinal gap of the box profile the associated ribs, which engage completely in the rollers made like rollers with grooves, so that the side rollers for guiding the box profile of the sliding door, which are known from AT-PS 357 739 or DE-PS 15 59 958, are unnecessary.

U osnovi zadatak izuma je, da već poznata klizna vrata pod AT-PS 383 853 poboljša i pojednostavi, pri čemu će se zadržati prednosti kliznih vrata AT-PS 383 853 (bez valjčića za bočno vođenje kao kod AT-PS 357 739). Basically, the task of the invention is to improve and simplify the already known sliding door under AT-PS 383 853, whereby the advantages of the sliding door AT-PS 383 853 will be maintained (without rollers for lateral guidance as in AT-PS 357 739).

Taj će se zadatak prema izumu riješiti tako, da je unutarnja strana gornjeg zida kutijastog profila, kao što je već poznato, ravno izrađena i da kutijasti profil uključujući i uzdužni, pokraj uzdužnog raspora kutijastog profila pripadajuća rebra na donjem zidu kutijastog profila su izrađena u jednom komadu, pri čemu neposredno pokraj uzdužnog raspora kutijastog profila pripadajući, s unutarnje strane rebara noseći predjeli donjeg zida kutijastog profila, oblikovani su odgovarajuće obrisu na unutra pokazujućim rebrima. According to the invention, this task will be solved in such a way that the inner side of the upper wall of the box profile, as is already known, is made flat and that the box profile, including the longitudinal, next to the longitudinal gap of the box profile, the corresponding ribs on the lower wall of the box profile are made in one piece, while immediately next to the longitudinal gap of the box profile, the corresponding parts of the lower wall of the box profile, on the inside of the ribs, are shaped according to the outline of the ribs pointing inward.

Izvedbeni oblici kojima se daje prednost kliznih vrata prema izumu su predmet podzahtjeva 2 do 4. The preferred embodiments of the sliding door according to the invention are the subject of sub-claims 2 to 4.

Time, da su kod kliznih vrata prema izumu samo na donjem zidu kutijastog profila na unutra naslonjeni valjčići za vođenje izrađeni kao valjčići s utorima, koji pokraj uzdužnog proreza, kotrljaju na unutra usmjerenim rebrima, kutijasti profil se može proizvesti od čeličnog lima, bez da je potreban skupi postupak oblikovanja valjanjem za proizvodnju dugih rebara u predjelu gornjeg zida. Ipak je moguće, za kutijasti profil primjeniti postupak istiskivanja aluminijskog profila. Daljnja prednost kliznih vrata prema izumu je u tome, da je poboljšana njihova mirnoća hoda, jer se gornji valjčići mogu izraditi kao cilindrični valjčići, ili kao valjčići s konveksnom vanjskom konturom po Due to the fact that in sliding doors according to the invention only on the bottom wall of the box profile, the guide rollers are made as rollers with grooves, which, next to the longitudinal slot, roll on the ribs directed inward, the box profile can be produced from sheet steel, without required an expensive roll forming process to produce long ribs in the upper wall area. However, it is possible to apply the aluminum profile extrusion procedure for the box profile. A further advantage of sliding doors according to the invention is that their smooth running is improved, because the upper rollers can be made as cylindrical rollers, or as rollers with a convex outer contour

njihovom obodu. their rim.

Daljnje pojedinosti i osobine izuma dane su iz slijedećeg opisa primjera prikazanog u crtežu izvedbenog oblika kliznih vrata prema izumu. Further details and features of the invention are given from the following description of the example shown in the drawing of the embodiment of the sliding door according to the invention.

Ta u crtežima djelomično prikazana klizna vrata sastoje se od jednog kutilastog profila 1, na kojem je umetak vrata 4 izrađen od drvenih letvi, ograda od kalupnih cijevi 4, ili tome sl. ili rešetka, npr. kovana rešetka. Kutijasti profil 1 nose stalci valjčića 3, koji su pričvršćeni na podu izvan otvora vrata. The partially shown sliding door in the drawings consists of a single-shaped profile 1, on which the door insert 4 is made of wooden slats, a fence made of molded pipes 4, or the like or a grid, for example a forged grid. The box profile 1 is supported by roller stands 3, which are attached to the floor outside the door opening.

Svaki stalak valjčića 3 ima dva točno ili pomaknuto jedno ispod drugoga postavljene parove valjčića 2, pri čemu valjčići 7 donjih parova valjčića 2 su izrađeni kao valjčići s utorima (usporedi sl. 2 i 3). Valjčići 8 gornjeg para valjčića 2 izrađeni su kao cilindrični valjčići. Mogu se predvidjeti također i valjčići 8 s konveksnom obodnom površinom, koji se na unutarnjoj ravno izrađenoj strani kotrljaju na gornjem zidu 10 kutijastog profila 1. Na unutarnjoj strani donjeg zida kutijastog profila 1 su predviđena uzdužna rebra, koja ulaze u utore valjčića 7 donjih parova valjčića 2. Each rack of rollers 3 has two pairs of rollers 2 placed exactly or shifted one below the other, whereby the rollers 7 of the lower pairs of rollers 2 are made as rollers with grooves (compare fig. 2 and 3). The rollers 8 of the upper pair of rollers 2 are made as cylindrical rollers. Rollers 8 with a convex peripheral surface can also be provided, which on the inner flat side roll on the upper wall 10 of the box profile 1. On the inner side of the lower wall of the box profile 1, longitudinal ribs are provided, which enter the grooves of the rollers 7 of the lower pairs of rollers 2.

Osobito kada su valjčići 7 donjeg para valjčića izrađeni od plastične mase, npr. poliamida, pokazalo se kao dobar izvedbeni oblik, kod kojega rebra imaju uglavnom obris u obliku polukruga. Especially when the rollers 7 of the lower pair of rollers are made of plastic, for example polyamide, it turned out to be a good design, in which the ribs have mostly a semicircular outline.

Razumije se, da se posebno kod velikih i time teških kliznih vrata mogu predviditi na svakom osloncu valjčića 3 dva gornja para valjčića 2 i/ili dva donja para valjčića 2. Također kod izvedbenog oblika, kod kojega su predviđena na osloncima valjčića 3 dva gornja i/ili dva donja para valjčića 2, mogu se valjčići 7,8, para valjčića 2 smjestiti točno jedan iznad drugoga ili jedan pokraj drugoga. It is understood that, especially in the case of large and therefore heavy sliding doors, two upper pairs of rollers 2 and/or two lower pairs of rollers 2 can be provided on each support of the rollers 3. Also in the embodiment, in which two upper and /or two lower pairs of rollers 2, rollers 7,8, pair of rollers 2 can be placed exactly one above the other or next to each other.

Kod rasporeda od tri para valjčića 2 po jednom osloncu valjčića 3 pokazao se kao dobar izvedbeni oblik, onaj kod kojega je jedan par valjčića 2 smješten u sredinu između dva druga para valjčića 2, tako da je osovina para valjčića 2 smještena u vrhovima prvenstveno jednog istokračnog ili istostraničnog trokuta. In the arrangement of three pairs of rollers 2 per one support of rollers 3, the one in which one pair of rollers 2 is located in the middle between two other pairs of rollers 2, so that the axis of the pair of rollers 2 is located primarily in the tops of one straight or an equilateral triangle.

Kao što je vidljivo iz sl. 2, rebra 6 predviđena na donjem zidu kutijastog profila 1 smještena su neposredno pokraj tamo predviđenog uzdužnog raspora 5, kroz koji strše oslonci valjčića 3 u unutrašnjost kutijastog profila 1. Rebra 6 na donjem zidu kutijastog profila 1 mogu se naravno proizvesti postupkom oblikovanja valjanjem, ako je kutijasti profil 1 proizveden iz čeličnog lima dobivenog postupkom valjanja. Pored toga, u prikazanom primjeru rebara 6 u principu polukružnog oblika, na donjem zidu kutijastog oblika 1 također su mogući i drugi oblici, npr. trokutasti ili četverokutasti oblici. Prednosti ima ali u principu polukružni oblik. As can be seen from Fig. 2, the ribs 6 provided on the lower wall of the box profile 1 are located directly next to the longitudinal gap 5 provided there, through which the roller supports 3 protrude into the interior of the box profile 1. The ribs 6 on the lower wall of the box profile 1 can be naturally produced by rolling forming process, if box profile 1 is produced from steel sheet obtained by rolling process. In addition, in the shown example of ribs 6 in principle semicircular shape, other shapes are also possible on the bottom wall of the box shape 1, for example triangular or quadrangular shapes. It has advantages, but in principle the semicircular shape.

Time, da u predjelu uzdužnog proreza 5 preoblikovanjem tih tamo položenih rubova čeličnog lima, iz kojeg je proizveden i kutijasti profil 1, proizvedena su predočena rebra 6, proizlazi povećana krutost kutijastog profila 1, tako da se osigurava egzaktno vođenje slobodno nosećih kliznih vrata. By reshaping the edges of the steel sheet laid there, from which the box profile 1 is also produced, in the area of the longitudinal slit 5, the presented ribs 6 are produced, resulting in increased rigidity of the box profile 1, so that the exact guidance of the freely supporting sliding door is ensured.

Sl. 4 pokazuje u presjeku i u povećanom mjerilu jedan izvedbeni oblik kutijastog profila 1 s prednosti, iz čeličnog lima, koji može biti proizvden valjanjem. Sl. 4 shows in section and on an enlarged scale one embodiment of the box profile 1 with advantages, made of sheet steel, which can be produced by rolling.
