SÄÄTÖRUUVIJÄRJESTELY OVENSULKIMESSA - STÄLLSKRUVARRANGEMANG VID EN DÖRRSTÄNGAREADJUSTING SCREW ARRANGEMENT IN THE DOOR CLOSER - STÄLLSKRUVARRANGEMANG VID EN DÖRRSTÄNGARE

Keksinnön kohteena on patenttivaatimuksen 1 johdanto-osan mukainen säätöruuvijärjestely ovensulkimessa.The invention relates to an adjusting screw arrangement in a door closer according to the preamble of claim 1.

5 Tällaisissa ovensulkimissa oven sulkeutuminen tapahtuu tavanmukaisesti jousielementin avulla, jolloin jousielementin esijännityksen säätämistä varten ovensuljin käsittää säätöruu-vijärjestelyn, johon kuuluu kierrettävä säätöruuvi ja tähän kiertein sovitettu säätömutteri, jota vastaan jousielementti 10 puristuu ovensulkimen mäntäelimen puristamana. Säätöruuvi on kierrettävästi tuettu ovensulkimen runkoon, jolloin sen kiertäminen pyrkii samalla kiertämään myös säätömutteria. Jotta säätöruuvin kiertäminen aikaansaa säätömutterin siirtymisen säätöruuvin pituussuunnassa, joka vastaa jousiele-15 mentin vaikutussuuntaa, säätömutterin kiertyminen on estettä vä .In such door closers, the door is normally closed by a spring element, the door closer comprising an adjusting screw arrangement for adjusting the bias of the spring element, comprising a rotatable adjusting screw and a threaded adjusting nut against which the spring element 10 is pressed by the door closure piston member. The adjusting screw is rotatably supported on the door closer body, so that when it is turned, it also tends to turn the adjusting nut. In order for the rotation of the adjusting screw to cause the adjusting nut to move in the longitudinal direction of the adjusting screw corresponding to the direction of action of the spring element, the rotation of the adjusting nut is preventable.

Eräässä tunnetussa ratkaisussa säätömutterin ulkokehällä on 0-rengas, joka pitää kitkan vaikutuksesta säätömutterin kiinni ovensulkimen sylinterikammiossa. Haittapuolena on ratkaisun 20 epäluotettavuus, sillä kitkavoimat eivät aina riitä pitämään säätömutteria kiertymättömänä sylinterikammioon nähden. Eräässä toisessa tunnetussa ratkaisussa säätömutteriin on järjestetty ulkoneva pykälä, joka on yhteistoiminnassa sylinterin sisäpintaan vastaavasti tehtyyn loveen. Ratkaisu . .25 on varsin mutkikas ja hankala toteuttaa.In a known solution, the outer circumference of the adjusting nut has a 0-ring which holds the adjusting nut in the cylinder chamber of the door closer due to friction. A disadvantage is the unreliability of the solution 20, as the frictional forces are not always sufficient to keep the adjusting nut non-rotating relative to the cylinder chamber. In another known solution, a protruding notch is arranged in the adjusting nut, which cooperates with a notch correspondingly made in the inner surface of the cylinder. The solution. .25 is quite complex and cumbersome to implement.

Keksinnön tarkoituksena on aikaansaada yllä mainittuun .. . ongelmaan uusi, rakenteeltaan yksinkertainen ja toimintavarma ratkaisu.The object of the invention is to provide the above-mentioned ... a new, simple and reliable solution to the problem.

Keksinnön tarkoitus saavutetaan patenttivaatimuksessa 1 ja - '30 alivaatimuksissa tarkemmin esitetyllä tavalla. Keksinnön mukaisesti säätömutterin reunassa on kammion sisäpintaa kohti :. 7 / j ί.The object of the invention is achieved as further specified in claims 1 and 30. According to the invention, at the edge of the adjusting nut, towards the inner surface of the chamber:. 7 / j ί.

2 avoin ja kammion poikkileikkaustasossa tietyn rajatun sektorin pituinen ura tai vastaava, jossa on säätömutterin suhteen liikuteltava pidätinkappale. Mainittu ura tai vastaava on muotoiltu siten, että säätöruuvin kiertäminen aikaansaa 5 pidätinkappaleen painumisen vasten kammion sisäpintaa niin että se estää säätömutterin kiertymisen samalla kun säätömut-teri siirtyy jousielementin vaikutussuunnassa.2 open and in the cross-sectional plane of the chamber a groove of a certain delimited sector or the like with a retaining piece movable relative to the adjusting nut. Said groove or the like is shaped so that the rotation of the adjusting screw causes the retaining piece 5 to press against the inner surface of the chamber so as to prevent the adjusting nut from rotating while the adjusting nut moves in the direction of action of the spring element.

Säätömutteri on edullisesti levymäinen kappale, jonka muoto sylinterimäisen kammion poikkileikkaustasossa vastaa pääasial-10 lisesti sylinterimäisen kammion muotoa.The adjusting nut is preferably a plate-like body having a shape in the cross-sectional plane of the cylindrical chamber which substantially corresponds to the shape of the cylindrical chamber.

Jotta valmistustoleranssit huomioon ottaen varmistetaan, että pidätinkappale saa riittävän kontaktin sylinterikammion sisäseinämästä, mainitun uran suurin syvyys valitaan pienemmäksi kuin pidätinkappaleen paksuus ja järjestetään uran 15 pituussuunnassa sen keskialueelle niin että ura madaltuu kohti säätömutterin reunaa.In order to ensure that the retaining piece makes sufficient contact with the inner wall of the cylinder chamber, taking into account manufacturing tolerances, the maximum depth of said groove is selected to be less than the thickness of the retaining piece and arranged in the longitudinal direction of the groove 15 so that the groove lowers towards the adjusting nut.

Mainittu ura vastaa muodoltaan edullisesti ympyrän segmenttiä ja sen pituus sylinterimäisen kammion poikkileikkaustasossa vastaa mieluiten alle 90° sektoria. Tällöin säätöruuvia 20 kierrettäessä pidätinkappale kiilautuu edullisesti säätömutte rin ja sylinterikammion sisäpinnan väliin.Said groove preferably corresponds in shape to a segment of a circle and its length in the cross-sectional plane of the cylindrical chamber preferably corresponds to a sector of less than 90 °. In this case, when the adjusting screw 20 is turned, the retaining piece preferably wedges between the adjusting nut and the inner surface of the cylinder chamber.

Pidätinkappale on edullisesti kuulamainen ja valmistettu teräksestä.The retaining body is preferably spherical and made of steel.

Keksintöä selostetaan seuraavassa tarkemmin viitaten oheiseen 25 piirustukseen, jossaThe invention will now be described in more detail with reference to the accompanying drawing, in which

Fig. 1 esittää erästä keksinnön mukaista säätöruuvijärjes-telyä leikattuna, ja - Fig. 2 esittää Fig. 1 leikkausta II-II.Fig. 1 shows a section of an adjusting screw arrangement according to the invention, and Fig. 2 shows a section II-II of Fig. 1.

Piirustuksessa tarkoittaa viitenumero 1 ovensulkimen runkoa, 30 jossa on sylinterimäinen kammio 2, joka sulkee sisäänsä jousielementin 3, joka ovea avattaessa puristuu sinänsä tunnetulla tavalla oven liikkeiden mukaan kammiossa 2In the drawing, reference numeral 1 denotes a door closer body 30 having a cylindrical chamber 2 which encloses a spring element 3 which, when opened, is compressed in a manner known per se according to the movements of the door in the chamber 2.
