Sulkumekanismilla varustettu huonekaluoven sarana Jakamalla erotettu hakemuksesta nro 832590 5 Keksintö kohdistuu sulkumekanismilla varustettuun huonekaluoven saranaan, Jossa ovipuoliskon puoleisessa saranapesässä kahden nivelvipuvarren sisemmät päät on kiertyvästi laakeroitu ja ulommat päät on sovitettu tarttumaan sarananvarteen muodostaen nivelnelikulmion, jolloin 10 sarananvarren sisäpuolelle on sovitettu jousiesijännitetty puristuskappale, joka on kiertyvästi laakeroitu sisemmälle nivelvipuvarrelle ja joka saranan kiinniasennossa tukeutuu ulomman nivelvipuvarren sarananvarren puoleiseen nivelak-seliin puristuskappaleen edullisesti kuperan tukipinnan 15 avulla.The invention relates to a furniture door hinge provided with a closing mechanism. mounted on the inner articulated arm and which, in the closed position of the hinge, rests on the hinge-side articulated shaft of the outer articulated arm by means of a preferably convex support surface 15 of the pressing piece.

Tällaisia, omalla sulkumekanismilla varustettuja saranoita tunnetaan runsaasti. Niiden etuna on ennen kaikkea se, että huonekalussa ei tarvita erillistä sulkuosaa, esimerkiksi magneettisäppiä. Tällainen sarana on esitetty 20 esimerkiksi DE-hakemusjulkaisussa 29 51 986. Siinä on si-semmälle nivelvarrelle kiertyvästi laakeroitu erillinen puristuskappale, jolle haarajousi kohdistaa paineen.Such hinges with their own closing mechanism are well known. Their main advantage is that the furniture does not require a separate closure, for example a magnetic latch. Such a hinge is disclosed, for example, in DE-A-29 51 986. It has a separate compression body rotatably mounted on the inner articulated arm, to which the branch spring applies pressure.

Keksinnön tehtävänä on saada aikaan edellä mainitun kaltainen sarana, jossa sulkumekanismi on toteutettu 25 vielä tiiviimmin ja rakenteellisesti yksinkertaisemmin.The object of the invention is to provide a hinge as mentioned above, in which the closing mechanism is implemented even more tightly and structurally simpler.

Tämä saavutetaan keksinnön mukaisesti siten, että puristuskappale on haarajousen haara.This is achieved according to the invention in that the compression body is a branch of a branch spring.

Käyttämällä haarajousta saavutetaan yksinkertaisin keinoin hyvä toimintavarmuus, koska haarajousi, toisin 30 kuin ruuvijousi, voidaan ankkuroida sarananvarteen yksinkertaisesti ilman ohjausvälineitä. Lisäksi voidaan luopua lisäpuristuskappaleesta sulkumekanismissa.By using a branch spring, good operational reliability is achieved by simple means, because the branch spring, unlike the screw spring, can be anchored to the hinge arm simply without control means. In addition, an additional compression piece in the closing mechanism can be dispensed with.

. . Keksinnön edullisen suoritusmuodon mukaisesti si- sempi nivelvipuvarsi on kaksivartinen vipuvarsi ja haara-35 jousi on kiertyvästi laakeroitu nivelvipuvarren saranan- 2 81876 varteen ulkonevalle varrelle.. . According to a preferred embodiment of the invention, the inner articulated lever arm is a two-arm lever arm and the branch-35 spring is rotatably mounted on a projecting arm of the articulated arm arm hinge arm.

Edullista on, että haarajousi painaa haaroillaan jatkuvasti välillisesti tai välittömästi sarananvarren molempia nivelakseleita.It is preferred that the branch spring continuously presses, indirectly or immediately, both articulated shafts of the hinge arm with its branches.

5 Jotta voitaisiin tarkkaan määritellä siirtyminen kiinnialueelta aukialueelle, edellytetään suoritusesimer-kissä sitä tulosta, että haarajousen haara, joka painaa ulomman nivelvipuvarren nivelakselia tai jotain muuta sarananvarren kiinteää osaa, on taivutettu ei-jatkuvaksi ja 10 määrää ohjauskäyrää.In order to precisely define the transition from the closed area to the open area, the exemplary embodiment requires the result that the branch of the branch spring pressing the pivot shaft of the outer articulated arm or some other fixed part of the hinge arm is bent non-continuously and determines the control curve.

Edullista on lisäksi, että haarajousen haarassa on kaksi toisiaan kohti kaareutunutta osaa.It is further preferred that the branch of the branch spring has two parts which are curved towards each other.

Seuraavassa kuvataan yksityiskohtaisesti keksinnön suoritusesimerkkiä oheisen piirustuksen kuvioon viitaten. 15 Kuvio esittää leikkausta keksinnön mukaisesta sa ranasta kiinniasennossa.An embodiment of the invention will now be described in detail with reference to the figure of the accompanying drawing. The figure shows a section of a hinge according to the invention in the closed position.

Kuten piirustuksen kuviosta nähdään, on keksinnön mukaisessa saranassa sarananvarsi 1, joka on kiinnitetty pohjalevyn 8 avulla huonekalun puoleiseen seinään 7. Poh-20 jalevyn 8 kiinnitys huonekalun puoleiseen seinään 7 tapahtuu tavallisesti ruuveilla tai tapeilla. Saranavarsi 1 pidetään pohjalevyllä 8 kiristysruuvin avulla. Sarana on varustettu lisäksi asetusruuvilla 11 sauman asettelua varten, joka sovitetaan sarananvarressa 1 mutterin kiertee-25 seen ja joka tukeutuu pohjalevyyn 8. Saranan saranapesä on sijoitettu ovenpuolikkaaseen.As can be seen from the figure of the drawing, the hinge according to the invention has a hinge arm 1 fixed to the furniture side wall 7 by means of a base plate 8. The fixing of the base plate 20 to the furniture side wall 7 is usually done with screws or pins. The hinge arm 1 is held on the base plate 8 by means of a clamping screw. The hinge is further provided with a set screw 11 for setting the seam, which is fitted on the hinge arm 1 to the thread 25 of the nut and which rests on the base plate 8. The hinge housing of the hinge is located on the door half.

Sarananvarsi 1 on yhdistetty saranapesään nivel-vipuvarsilla 3,6, jotka on sarananvarrella 1 laakeroitu nivelakseleille 12,13 ja lisäksi laakeroitu nivelakseleil-30 le (14,15 ei mukana kuviossa) saranapesässä.The hinge arm 1 is connected to the hinge housing by articulated lever arms 3,6 which are mounted on the articulated shafts 12,13 by the hinge arm 1 and further mounted on the articulated shafts 30 (not shown in the figure) in the hinge housing.

Sisempi nivelvipuvarsi 6 on toteutettu kaksivar-tisena vipuvartena, joka pyörii sarananvarren 1 nivelak-selin 12 ympäri. Nivelvipuvarren haaran 6’ vapaassa päässä, ts. nivelakseleiden 12 (ja 14) laakeripaikkojen ulko-35 puolella, on tapille 16 laakeroitu puristuskappale, joka 3 81 876 muodostetaan haarajousen 21 haarasta.The inner articulated arm 6 is realized as a two-arm lever arm which rotates around the articulated shaft 12 of the hinge arm 1. At the free end of the articulated arm arm branch 6 ', i.e. on the outside 35 of the bearing positions of the articulated shafts 12 (and 14), there is a compression piece mounted on the pin 16, which 3 81 876 is formed from the branch 21 of the branch spring.

Haarajousi 21 tukeutuu suoraan sarananvarren 1 ni-velakseleihin 12,13. Ulomman nivelvipuvarren 3 nivelakse-11 13, jota vasten purlstuskappaleeksi muodostettu haara-5 jousen 21 haara 4 siirtyy, on varustettu rullalla 23 kitkan vähentämiseksi.The branch spring 21 rests directly on the ni shafts 12,13 of the hinge arm 1. The pivot shaft-11 13 of the outer articulated arm 3, against which the branch 4 of the spring-21 branch 21 formed as a spray body moves, is provided with a roller 23 to reduce friction.

Haarajousen 21 puristuskappaleena toimivalla haaralla 4 on kaksi kaarreosaa 4' ja 4", jotka kaareutuvat toisiaan kohti. Ulompi kaarreosa 4' vastaa saranan auki-10 asentoa. Kiinniasennossa on painopiste haarajousen 21 tämän haaran 4' ja puristuskappaleena 4 toimivan haarajousen 21 haaran 4 osan 4' ja osan 4" välissä sijaitsevan nivelakselin 13 rullan 23 välissä.The branch 4 acting as a compression piece of the branch spring 21 has two curved parts 4 'and 4 "which curve towards each other. The outer curved part 4' corresponds to the open position 10 of the hinge. 'and between the roller 23 of the PTO shaft 13 located between the part 4 ".

Keksinnön mukaisella sijoituksella tukeutuu haara-15 jousi 21 jatkuvasti nivelakseleihin 12,13, mutta painaa kuitenkin kiinniasennossa sisempää nivelvipuvartta 6 sul-keutumissuuntaan, ts. ovenpuolisko pysyy suljettuna.With the arrangement according to the invention, the branch-15 spring 21 continuously rests on the articulated shafts 12,13, but in the closed position still presses the inner articulated lever arm 6 in the closing direction, i.e. the door half remains closed.

Ovenpuoliskoa avattaessa ei haarajouseen 21 kohdistu kuormitusta, joten ovenpuoliskoa suljettaessa tai avat-20 taessa ei tarvitse voittaa vastapainetta.When the door half is opened, the branch spring 21 is not loaded, so when closing or opening the door half, it is not necessary to overcome the back pressure.
