Opfindelsen angår et skydedørsbeslag, især til anbringelse på underkanten af skydedøre, og som omfatter et med kørehjul forsynet hus, der kan fastgøres i skydedøren ved indsættelse i et helt eller delvis polygonalt hul deri, f.eks. et hul dannet af 5 en halvcirkel og et tilgrænsende rektangel.The invention relates to a sliding door bracket, in particular for mounting on the lower edge of sliding doors, and which comprises a housing provided with a wheel which can be fixed in the sliding door by insertion into a fully or partially polygonal hole therein, e.g. a hole formed by 5 a semicircle and an adjacent rectangle.

Fra FR offentliggørelsesskrift nr. 26 12 930 kendes et skydedørsbeslag til montering i den nedre kantflade af et vindue eller en dør, og hvor skydedørsbeslaget, som består af et hus 10 og et deri monteret kørehjul, er indlagt i en udtagning i den nedre kantflade. Kørehjulet er fastgjort i huset ved at en aksel, der går gennem kørehjulet, er ført igennem huller i nogle sidedele i huset. Kørehjulet er således ikke snappet fast. På grund af de nævnte huller og på grund af støv og urenheder er 15 der en risiko for, at kørehjulet sætter sig fast, eventuelt kæntrer.FR publication No. 26 12 930 discloses a sliding door bracket for mounting in the lower edge surface of a window or a door, and where the sliding door bracket, which consists of a housing 10 and a drive wheel mounted therein, is inserted in a recess in the lower edge surface. The drive wheel is fixed in the housing by a shaft passing through the drive wheel being passed through holes in some side parts of the housing. The drive wheel is thus not snapped. Due to the mentioned holes and due to dust and impurities there is a risk that the driving wheel gets stuck, possibly overturns.

Fra DE patentskrift nr. 36 16 242 kendes en indstillelig bære-og løberulleindretning til skydedøre, og hvori der indgår en 20 indstillingsaksel, som har en rundtgående notgang. Akslen er ud for notgangen snappet fast mellem de frie flige af et af metal fremstillet U-formet spærrelegeme. Ved drejning af indstillingsakselen, der virker som excentrik, kan der kompenseres for eventuelle højdeforskelle i forbindelse med skydedøre-25 ne. Denne bære- og rulleindretning er yderst kompliceret.DE patent specification no. 36 16 242 discloses an adjustable support and roller device for sliding doors, and in which an adjusting shaft is included, which has a circumferential groove passage. Next to the groove, the shaft is snapped between the free tabs of a metal-made U-shaped locking body. By turning the adjusting shaft, which acts as an eccentric, any height differences in connection with the sliding doors 25 can be compensated for. This carrying and rolling device is extremely complicated.

Formålet med opfindelsen er at anvise et skydedørsbeslag af den indledningsvis angivne art, der muliggør et bedre styr på kørehjulet, når skydedøren forskydes, idet man undgår risiko 30 for kæntring og indvirkning fra støv af urenheder.The object of the invention is to provide a sliding door fitting of the type indicated in the introduction, which enables a better control of the driving wheel when the sliding door is displaced, while avoiding the risk of overturning and the impact of dust from impurities.

Skydedørsbeslaget ifølge opfindelsen er ejendommelig ved, at kørehjulet er fastgjort ved hjælp af i huset tilvejebragte, radialt virkende snaporganer samt aksialt virkende snap- eller 35 stydedele, og at snaporganerne har 1ejebæref1 ader, hvorpå kørehjulet eller dele heraf kan glide, og som eventuelt findes på separate lejedele, der er indlagt i snaporganerne. HervedThe sliding door fitting according to the invention is characterized in that the drive wheel is fastened by means of radially acting snap means provided in the housing and axially acting snap or 35 support parts, and that the snap means have bearing supports on which the drive wheel or parts thereof can slide and which may be separate bearing parts embedded in the snap means. Hereby

2 opnås et både radialt og aksialt forbedret styr på kørehjulet, når skydedøren forskydes, idet man undgår risiko for kæntring, hvortil kommer, at skydedørsbeslaget bliver mindre følsomt over for støv og urenheder. Støv og urenheder kan næsten ikke 5 sætte sig fast, men glider væk fra kørehjulet via snaporganernes snævreste sted. - I øvrigt opnås, at kørehjulet - som følge af snaporganerne - kan monteres meget let i huset uden brug af specialværktøj. Kørehjulet kan monteres i huset før eller efter at sidstnævnte er blevet fastgjort i skydedøren.2, both radially and axially improved steering on the drive wheel is achieved when the sliding door is displaced, avoiding the risk of tipping over, in addition to which the sliding door fitting becomes less sensitive to dust and impurities. Dust and impurities can hardly get stuck, but slide away from the driving wheel via the narrowest point of the snap members. - It is also achieved that the driving wheel - as a result of the snap means - can be mounted very easily in the house without the use of special tools. The drive wheel can be mounted in the housing before or after the latter has been attached to the sliding door.

En udformning af skydedørsbeslaget ifølge opfindelsen er ejendommelig ved, at snaporganerne udgøres af mindst ét i hovedsagen U-formet legeme, hvor de frie ben har mod hinanden vendende konvergerende styreflader, der løber over i lejebærefla-15 den, og hvor den mindste afstand x mellem styrefladerne er mindre end diameteren af 1ejebæref1aden. Herved opnås let montering af kørehjulet og god snapvirkning omkring dette.A design of the sliding door fitting according to the invention is characterized in that the snap means are constituted by at least one substantially U-shaped body, the free legs having facing each other converging guide surfaces, which run over into the bearing support surface, and where the smallest distance x between the guide surfaces are smaller than the diameter of the bearing surface. This achieves easy mounting of the drive wheel and good snap effect around this.

Skydedørsbeslaget ifølge opfindelsen kan være således udfor-20 met, at 1ejebæref1aderne strækker sig over en vinkel v omkring kørehjulet på mindst 190°, fortrinsvis ca. 240°. Herved opnås store lejeflader og således forøget holdbarhed af disse.The sliding door fitting according to the invention can be designed such that the bearing support surfaces extend over an angle v around the driving wheel of at least 190 °, preferably approx. 240 °. This achieves large bearing surfaces and thus increased durability of these.

For at opnå en materialebesparelse kan ifølge opfindelsen kø-25 rehjulet have en aksel, der eventuelt er en integrerende del af dette, hvorhos snaporganerne kan gribe radialt om akslen.In order to achieve a material saving, according to the invention the drive wheel can have a shaft, which is optionally an integral part thereof, in which case the snap means can grip radially about the shaft.

Ifølge opfindelsen kan huset og snaporganerne være udformet ud i et, hvorved skydedørsbeslaget bliver enklere.According to the invention, the housing and the snap means can be formed integrally, whereby the sliding door fitting becomes simpler.
