Den foreliggende opfindelse angår skruehængsler af den art, der indbefatter to hoveddele, en bøjledel og en topdel, der hver har et med gevind forsynet fastgørelsesorgan, samt en ledtap, som er forankret i et i hver bøjlegren indskruet forankringsorgan og ført gennem en 5 boring i tapdelen.BACKGROUND OF THE INVENTION The present invention relates to screw hinges of the type including two main parts, a hanger portion and a top portion, each having a threaded fastener, and a hinge pin anchored in an anchorage screwed into each hanger branch and passed through a bore in male portion.

Kendte skruehængsler af denne art tillader simpel relativ indstilling i sideretningen af to ved hjælp af hængslet forbundne dele, f.eks. en dør eller et vindue i forhold til dets ramme.Known screw hinges of this kind allow simple relative alignment in the lateral direction of two parts connected by the hinge, e.g. a door or window relative to its frame.

Hidtil kendte skruehængsler af denne art har imidlertid ikke samtidigt 10 muliggjort en simpel og pålidelig indstilling i højderetningen, og den foreliggende opfindelse har til formål at afhjælpe denne mangel.However, hitherto known screw hinges of this kind have not simultaneously allowed a simple and reliable height adjustment, and the present invention aims to remedy this defect.

USA patentskrift nr. 2.209.125 beskriver et hængsel af mere eller mindre konventionel art, hvor det er muligt at foretage indstilling i højderetningen. Der er her således ikke tale om et hængsel af den 15 ovenfor angivne art. Selve indstillingsoperationen er endvidere forholdsvis kompliceret og forudsætter løsning af øverste og nederste låseskruer og borttagning af øverste og nederste beskyttelseskapper, inden indstillingen i højderetningen kan foretages. Når dette er tilendebragt, påsættes beskyttelseskapperne igen og forankres ved 20 hjælp af låseskruerne.United States Patent No. 2,209,125 discloses a hinge of a more or less conventional nature where it is possible to adjust the height. This is not a hinge of the kind mentioned above. Furthermore, the adjustment operation itself is relatively complicated and requires the removal of the upper and lower locking screws and removal of the upper and lower protective caps before the adjustment in the height direction can be made. When this is completed, the protective caps are reattached and anchored by the locking screws.

Det tyske offentliggørelsesskrit nr. 2.313.293 beskriver et skruehængsel, som dog ikke er af den ovenfor angivne art, idet den savner en bøjledel. Ved dette hængsel er der stor risiko for, at den møtrik, der fikserer de to hængselshalvdele i forhold til hinanden i 25 højderetningen, skal gå løs som følge af den momentvirkning, der udøves af den bevægelige hængselsdel. Det kendte hængsel har således ikke tilstrækkelig stor pålidelighed.German Patent Publication No. 2,313,293 discloses a screw hinge, which, however, is not of the type mentioned above, since it lacks a hanger part. At this hinge, there is a high risk that the nut that fixes the two hinge halves relative to each other in the 25 height direction will loosen due to the torque effect exerted by the movable hinge portion. Thus, the known hinge does not have sufficient reliability.

I det engelske patentskrift nr. 557.160 beskrives en momentoverførende kobling indbefattende en bøjledel og en tapdel. Formålet med 30 denne kobling, der har et forholdsvis kompliceret lejringsarrangement, der forudsætter udnyttelse af delvis sfæriske eller koniske lejeflader, er, at man mellem koblingens dele skal kunne overføre 151348 2 et vridningsmoment. Dette er helt og holdent i strid med formålet ifølge den foreliggende opfindelse, hvor det i stedet kræves, at tapdelen skal kunne bevæge sig med mindst mulig friktion i forhold til bøjledelen samtidig med, at der tillades en simpel indstilling i højde-5 retningen og uden at hængslets pålidelighed går tabt.British Patent No. 557,160 discloses a torque transmitting coupling including a bracket member and a pin member. The purpose of this clutch, which has a relatively complicated bearing arrangement which requires the use of partially spherical or tapered bearing surfaces, is that between the parts of the clutch it must be possible to transfer a torque. This is completely contrary to the purpose of the present invention, where instead it is required that the pin member be able to move with the least possible friction with respect to the bend part while allowing a simple height adjustment and without that the reliability of the hinge is lost.

Et indstilleligt hængsel af den ovenfor angivne art, som opfylder dette formål, er i overensstemmelse med den foreliggende opfindelse ejendommeligt ved, at begge forankringsorganernes mod hinanden rettede ender danner lejeflader for tapdelen, at det ene med gevind 10 forsynede forankringsorgan er forenet med ledtappens ene ende under dannelse åf et med gevind forsynet hoved på denne, og at ledtappens anden ende er ført således mod bunden i en udsparing i det andet med gevind forsynede forankringsorgan, at afstanden mellem forankringsorganernes modsat rettede, som lejeflader tjenende endeflader 15 noget overstiger tapdelens højde.According to the present invention, an adjustable hinge of the above-mentioned type which fulfills this purpose is characterized in that both ends of the anchorage means form bearing surfaces for the pin member, the one threaded anchorage member is joined to one end of the linkage pin. forming a threaded head thereon, and the other end of the hinge pin is guided so as to the bottom of a recess in the other threaded anchor means that the distance between the anchoring members directed as bearing surfaces serving end faces 15 exceeds the height of the loss member.

De to med gevind forsynede forankringsorganers modsat rettede flader danner hensigtsmæssigt lejeflader for tapdelen samtidig med, at de med enkle midler sikrer pålidelig indbyrdes låsning mellem hængselsdele. Indstillingen i højderetningen af hængslerne er endvidere 20 særdeles enkel at udføre, idet denne kan ske direkte, uden at nogle sikrings- eller låsestifter, beskyttelseskapper eller lignende først behøver at blive fjernet.Conveniently, the two opposite faces of the threaded anchoring members form bearing surfaces for the tapping member while at the same time ensuring reliable interlocking between hinge members. The adjustment in the height direction of the hinges is furthermore extremely simple to carry out, since this can be done directly, without the need to remove any securing or locking pins, protective caps or the like.

Ved indstillingen i højderetningen behøver man således kun først at løsgøre det ene forankringsorgan, foretage den ønskede indstilling i 25 højderetningen og derefter påny tilvejebringe sikring og i forbindelse dermed sikre, at ledtappen føres mod bunden i udsparingen i det andet forankringsorgan.Thus, when adjusting in the height direction, one only has to loosen one anchor, make the desired height adjustment and then again provide fuse and thereby ensure that the link pin is guided to the bottom of the recess in the other anchor.

Tapdelen kan have en i hovedsagen cylindrisk udformning, idet de to forankringsorganers modsat rettede lejeflader passende har en ind-30 byrdes afstand, der er noget større end tapdelens højde. De to forankringsorganers modsat rettede flader er da passende i hovedsagen plane, men det kan også tænkes, at disse kan have en anden form, hvilket i så fald som regel forudsætter en tilsvarende, eksempelvis konisk eller sfærisk udformning af tapdelens endeflader.The tapping member may have a generally cylindrical configuration, with the opposite bearing faces of the two anchoring members suitably having a spacing which is somewhat greater than the height of the tapping member. The opposite faces of the two anchoring members are then suitably substantially planar, but it is also conceivable that these may have a different shape, which in this case usually requires a corresponding, for example, tapered or spherical configuration of the end faces of the tab member.

En speciel fordel ved skruehængslet ifølge opfindelsen er, at gevindindgrebet med bøjledelen ved udtrækning af forankringsorganet som følge af fjedervirkning i bøjledelens ben frembringer en sådan friktionslåsning af forankringsorganet, at en ændret højdeindstilling af 5 tapdelen som følge af utilsigtet løsgøring af forankringsorganet undgås selv ved hyppige drejningsbevægelser for tapdelen.A particular advantage of the screw hinge according to the invention is that the threaded engagement with the bracket part upon pulling out of the anchor means due to spring action in the legs of the bracket provides such a friction locking of the anchor means that an altered height adjustment of the pin part as a result of unintentionally loosening the anchorage means is prevented. for the loss section.

Denne for et med bøjledel forsynet skruehængsel ifølge opfindelsen specielle funktion er meget vigtig, idet den sikrer, at hængslet kan fungere fejlfrit i et betydeligt tidsrum, uden at man behøver at 10 befrygte, at den vridningsmomentvirkning, som tapdelen vil udøve på ledtappen, når tapdelen udfører gentagne svingningsbevægelser frem og tilbage, behøver at føre til, at den tilsigtede indstilling i højderetningen ændres. Hvis man på den anden side af en eller anden grund ønsker at ændre indstillingen i højderetningen, kan dette som nævnt 15 ovenfor ske særdeles simpelt.This particular feature of a bracket hinge according to the invention is very important in that it ensures that the hinge can function flawlessly for a considerable period of time without having to worry about the torque effect that the tapping member will exert on the hinge pin when the tapping member performing repeated oscillatory movements back and forth need to change the intended altitude setting. If, on the other hand, for some reason you want to change the setting in the height direction, as mentioned above, this can be done very simply.

En i en vis udstrækning modificeret udførelsesform for skruehængslet ifølge opfindelsen er ejendommelig ved, at ledtappen har en sådan længde, at dens ende indgår i udsparingen i det andet med gevind forsynede forankringsorgan, inden hovedets gevind indgriber i bøjle-20 delens gevind.A somewhat modified embodiment of the screw hinge according to the invention is characterized in that the hinge pin is of such a length that its end is included in the recess in the second threaded anchorage member before the thread of the head engages in the thread of the bracket part.

Et skruehængsel af denne art er i mange tilfælde lettere at arbejde med og særligt ved montering i svært tilgængelige stillinger. Ledtappen kommer således til at indgå i og styres af det andet med gevind forsynede forankringsorgan, inden hovedet går i indgreb med bøjle-25 delen, hvilket forenkler arbejdet, især når den, der udfører dette, ikke kan se hængslet.A screw hinge of this kind is in many cases easier to work with and especially when mounted in difficult to reach positions. Thus, the articulated pin will engage and be guided by the second threaded anchorage member before the head engages the bracket member, which simplifies the work, especially when the person performing it cannot see the hinge.

En særlig formålstjenlig udførelsesform opnås da, hvis ledtappens i udsparingen i forankringsorganet indgående ende har mindre diameter end sin lejringsdel. Også udsparingen får da en mindre diameter, 30 hvilket indebærer, at det andet med gevind forsynede forankringsorgan som helhed kan gives reducerede ydermål.A particularly useful embodiment is then obtained if the end of the articulated pin included in the recess in the anchoring means has a smaller diameter than its bearing part. Also, the recess will then have a smaller diameter, which means that the second threaded anchoring device as a whole can be given reduced outer dimensions.

151348 4151348 4

Dette fører igen til, at det med gevind forsynede hul i bøjledelen får en reduceret diameter.This, in turn, results in a reduced diameter of the threaded hole in the hoop section.

I det følgende vil et par udførelsesformer for hængslet ifølge opfindelsen blive nærmere beskrevet under henvisning til tegningen, på 5 hvilken fig. 1 viser et skruehængsel ifølge opfindelsen i sin anvendelsesstilling set i perspektiv, fig. 2 et lodret snit i det i fig. 1 viste hængsel, fig. 3 i større målestok et lodret snit i en del af skruehængslet, idet 10 figuren anskueliggør en speciel mulighed for indstilling i højderetningen, og fig. 4 et til fig. 2 svarende lodret snit i en speciel udførelsesform.In the following, a few embodiments of the hinge of the invention will be described in greater detail with reference to the drawing, in which: 1 is a perspective view of a screw hinge according to the invention in its application position; FIG. 2 shows a vertical section in the embodiment of FIG. 1; FIG. 3 is an enlarged vertical sectional view of a portion of the screw hinge, FIG. 10 illustrating a special option for height adjustment; and FIG. 4 is a view of FIG. 2 corresponding to vertical section in a special embodiment.

Fig. 1 viser en dør 6, der er anbragt i en dørramme 7 ved hjælp af et i højderetningen indstilleligt skruehængsel, der er vist i fig. 2, og 15 som består af en bøjledel 1, der er forsynet med et med gevind forsynet fastgørelsesorgan Ib og to parallelle ben la. De to ben omslutter skruehængslets tapdel 2, som består af en cylindrisk lejringsdel 2a og et med gevind forsynet fastgørelsesorgan 2b.FIG. 1 shows a door 6 arranged in a door frame 7 by means of a height-adjustable screw hinge shown in FIG. 2 and 15, which consists of a bend portion 1 provided with a threaded fastener 1b and two parallel legs 1a. The two legs enclose the screw portion 2 of the screw hinge, which consists of a cylindrical bearing portion 2a and a threaded fastener 2b.

Hængslets to dele sammenholdes af en ledtap 3, der ved den viste ud-20 førelsesform består af et med gevind forsynet hoved 3a, som er udført i ét stykke med en cylindrisk tap 3b. Hovedet 3a har en skrue-kærv 3c, og dets gevind 3d indgriber i et gevindhul i bøjledelens øverste ben la.The two parts of the hinge are held together by a hinge pin 3 which, in the embodiment shown, consists of a threaded head 3a, which is integrally formed with a cylindrical pin 3b. The head 3a has a screw notch 3c, and its thread 3d engages in a threaded hole in the upper leg 1a of the hoop member.

Tappen 3b er ført gennem en boring 2c i den cylindriske lejringsdel 25 2a og er ført ind i en udsparing 4b i et nederste forankringsorgan 4, der er forsynet med gevind 4d, ved hjælp af hvilke forankringsorganet er indskruet i et gevindhul i bøjledelens nederste ben la.The pin 3b is passed through a bore 2c in the cylindrical bearing part 25 2a and is inserted into a recess 4b in a lower anchorage member 4 provided with thread 4d, by means of which the anchorage means is screwed into a threaded hole in the lower leg 1a of the hoop member .

Også det nederste forankringsorgan 4 har en skruekærv, der er betegnet med 4c. 1Also, the lower anchor member 4 has a screw notch designated by 4c. 1

Diameteren for udsparingen 4b i det nederste forankringsorgan er sådan, at den kan optage ledtappen 3b, og når denne er ført mod bunden i udsparingen, udgør afstanden mellem det nederste foran- 5 151348 kringsorgan 4's øverste endeflade og hovedet 3a's nederste endeflade en værdi, som noget overstiger højden af tapdelen 2's cylindriske parti. Derved tillades drejning af tapdelen i forhold til bøjledelen uafhængigt af, hvor hårdt de to forankringsorganer, nemlig det øverste 5 hoved og det nederste med udsparingen forsynede organ 4 er indskruet i de respektive ben la. De to forankringsorganers modsat rettede flader danner således passende lejeflader for tapdelen 2.The diameter of the recess 4b in the lower anchoring means is such that it can receive the link pin 3b, and when it is brought towards the bottom of the recess, the distance between the upper end surface of the lower locking member 4 and the lower end surface of the head 3a is a value which somewhat exceeds the height of the cylindrical portion of the pin portion 2. This allows rotation of the pin portion relative to the bracket portion regardless of how hard the two anchoring means, namely the upper 5 head and the lower member 4 provided with the recess, are screwed into the respective legs 1a. The opposite faces of the two anchoring members thus form suitable bearing surfaces for the pin portion 2.

Ved tilspænding af de to forankringsorganer 3a og 4 ved hjælp af en skruetrækker sikrer benene 1a's fjedervirkning, at gevindindgrebet 10 så hårdt fastlåser de respektive forankringsorganer - med forudbestemt, eksakt indbyrdes afstand - i bøjledelen, af den momentvirkning, der vil blive udøvet af tapdelen 2 ved dennes drejningsbevægelser i forhold til bøjledelen, aldrig kan frembringe et vridningsmoment, som løsner noget af de to forankringsorganer henholdsvis 3a og 15 4. Dette indebærer således, at hængslet aldrig vil behøve at blive udsat for utilsigtet ændring af højdeindstillingen.By tightening the two anchoring means 3a and 4 by means of a screwdriver, the spring action of the legs 1a ensures that the threaded engagement 10 so tightly locks the respective anchoring means - with predetermined, precisely spaced distance - in the bracket part, of the torque effect that will be exerted by the pin portion 2. by its rotational motions relative to the hoop portion, can never produce a torque which releases either of the two anchoring means 3a and 15 respectively. This means that the hinge will never have to be subjected to an unintended change in height.

Når man ønsker at ændre hængslets indstilling i høj de retningen, løsnes eksempelvis først det nederste forankringsorgan 4, at det skrues nogle omdrejninger, hvorefter det øverste forankringsorgan 20 skrues enten i retning med eller mod urets omløbsretning afhængigt af, om man ønsker, at tapdelen skal blive sænket eller hævet. Når man har opnået en korrekt ny stilling, tilspændes det nederste forankringsorgan 4 så hårdt, at den nævnte forankring som følge af benenes fjedervirkning opnås.For example, when one wishes to change the setting of the hinge in that direction, first the lower anchor member 4 is loosened to screw some turns and then the upper anchor 20 is screwed either in the clockwise or counterclockwise direction depending on whether the pin portion is to be be lowered or raised. When a correct new position is obtained, the lower anchorage member 4 is tightened so that the said anchorage is obtained as a result of the spring action of the legs.

25 I fig. 3 er den indstilling i højderetningen, det er muligt at foretage med et hængsel ifølge opfindelsen, anskueliggjort med punkterede linjer.In FIG. 3, the height adjustment that can be made with a hinge according to the invention is illustrated by dashed lines.

Ved den i fig. 4 viste modificerede udførelsesform har ledtappen 3b en nederste forlængelsesdel 3b' med en mindre diameter end den som 30 lejringsdel tjenende del af ledtappen. Forankringsorganet 4 er følgelig forsynet med en udsparing 4b' med mindre diameter end ved den ovenfor beskrevne udførelsesform, hvilket resulterer i, at forankringsorganet 4 som helhed har fået en mindre diameter. I stedet forIn the embodiment shown in FIG. 4, the link pin 3b has a lower extension portion 3b 'having a smaller diameter than the portion of the link pin serving as a bearing member. Accordingly, the anchoring means 4 is provided with a recess 4b 'of smaller diameter than in the embodiment described above, which results in the anchoring means 4 as a whole having a smaller diameter. Instead of

Claims

151348, this anchoring means has a greater axial length, thereby obtaining the advantage that the end 3b 'of the link pin 3b can be inserted into the recess 4b' before the thread of the head 3a engages with the thread in the upper leg 1a of the hoop member. This facilitates the mounting of the screw-5 hinge, especially in difficult-to-reach positions, where the person performing the work is unable to see the hinge. Furthermore, since the hinged anchor member 4 has a smaller diameter, the threaded hole in the lower leg of the hoop member also achieves a reduced diameter. As shown in FIG. 4, the head of the hinge pin in this embodiment is also given a slimmer shape and a larger axial length. Claims.
