Abstract

The fixture device (1) is provided with a longitudinal slot (6), in which a fastening unit (10) is inserted for fixing the frame (4) in the opening (8). The fastening unit is insertable in the slot from within the frame with an anchoring part. The anchoring part is pivotable through the slot with a smaller arm than the slot to a position outside the frame. In this position the fastening unit is displaceable towards and pressable firmly against the wall (9) surrounding the opening. A housing (3) is laterally located on the frame, which comprises three frame arms (5) with the same reciprocal angular distance. These arms are provided with central longitudinal slots and with their lower ends are fixed to a base ring (7). The base ring together with the frame accommodates a reflector and is inserted in the opening in the ceiling or wall plate.

I fig 1 föreställer l en fästanordning enligt uppfinningen i sin helhet. Fästanordningen är enligt fig l ansluten till och integre- rad i en elektrisk beslysningsarmatur 2 med ett sidobeläget hus 3 vid ett stativ 4, vilket huvudsakligen består av t ex tre med samma inbördes vinkelavstånd anordnade stativskänklar 5, som är försedda med centrala längsgående slitsar 6, och som med sina nedre ändar är fastsatta vid t ex en basring 7 avsedd att tillsammans med stativet upptaga en ej visad reflektor och införas i en öppning 8 i en tak- eller väggskiva 9.In Fig. 1, 1 represents a fastening device according to the invention in its entirety. According to Fig. 1, the fastening device is connected to and integrated in an electric lighting fixture 2 with a side-mounted housing 3 at a frame 4, which essentially consists of, for example, three frame legs 5 arranged at the same mutual angular distance, which are provided with central longitudinal slots 6, and which with their lower ends are attached to, for example, a base ring 7 intended to receive together with the stand a reflector (not shown) and inserted into an opening 8 in a roof or wall panel 9.

Vid införande av beskrivna delar i öppningen 8, kantras närmast hu- set snett in och träs sedan stativet 4 genom öppningen, tills bas- ringens 7 stoppfläns anligger mot rumssidan av väggmaterialet. Som synes, är stativskänklarna något sneda och upptill vinklade i rikt- ning mot det gemensamma övre centrumet, så att stativet liknar en stympad kon. Nämnda övre vinklade skänkeldelar är exempelvis fästa i ett utsprång från huset 3. Uppfinningen är dock tillämpbar även på både skänklar, som är rätvinkliga eller godtyckligt böjda i för- hållande till öppningsplanet. Det måste inte ens var fråga om skänklar. Det kan rentav röra sig enbart om ett mer eller mindre slutet hus, i vilket förutom nämnda slitsar 6 eventuellt finns ge- nombrott för att i viss mån göra utrymmet bakom stativet/huset åt- komligt. Sådana genombrott är dock ej nödvändiga för uppfinningens funktion.When inserting the described parts into the opening 8, the nearest house is tilted inwards and then the frame 4 is threaded through the opening, until the stop flange of the base ring 7 abuts against the room side of the wall material. As can be seen, the stand legs are slightly oblique and angled at the top in the direction of the common upper center, so that the stand resembles a truncated cone. Said upper angled leg parts are for instance fastened in a projection from the housing 3. However, the invention is also applicable to both legs, which are at right angles or arbitrarily bent in relation to the opening plane. It does not even have to be about legs. It can even only be a more or less closed house, in which in addition to the mentioned slots 6 there may be breakthroughs to make the space behind the stand / house accessible to a certain extent. However, such breakthroughs are not necessary for the operation of the invention.

Lämpligen före den ovan beskrivna insättningsoperationen har i varje slits 6 införts ett fästdon 10 inifrån stativet. Fästdonen intar härvid ett läge, som är visas längst ned i fig 1.Suitably before the insertion operation described above, a fastener 10 from inside the frame has been inserted into each slot 6. In this case, the fasteners assume a position which is shown at the bottom of Fig. 1.

Varje fästdon 10 är bockat av fjäderstål och har en huvudsakligen företrädesvis L-formigt bockad banddel ll med en långskänkel 12 ut- 10 15 20 25 30 3 mynnande vid sin fria ände i en i riktning bort från kortskänkeln 14 som exempelvis en tredjedels cirkel bockad fjäderfot 13. Kort- skänkeln 14 är vid sin fria ände bockad i rät vinkel uppåt till bildande av en kvarhållningsflik 15, som är förlängd i planled åt varje sida till bildande av öron 18, som vart har ungefärligen samma bredd som fliken.Each fastener 10 is bent of spring steel and has a substantially preferably L-shaped bent band portion 11 with a long leg 12 opening at its free end in a direction away from the short leg 14 such as a third circle bent spring foot 13. The short leg 14 is bent at its free end at right angles upwards to form a retaining flap 15, which is extended in a planar direction on each side to form ears 18, each of which has approximately the same width as the flap.

Omedelbart före fliken 15 är från kortskänkelns båda långsidor boc- kade i rät vinkel uppåt inbördes parallella styrflänsar 16, vars utsidor lämpligen ligger i plan med resp långsidor av skänklarna 14 och 12, och vars från fliken vända sidokanter lämpligen är uppdrag- na i form av mjuka rundningar för att ungefärligen i nivå med fli- kens övre eller fria begränsningskant bli rätvinkliga i förhållande till skänklarn 14 och sluta på en t ex 1 - 3 mm högre nivå, där styrflänsarna är bockade i rät vinkel utåt till bildande av fler- funktionsöron 17. Dessa sträcker sig dock på den mot fliken 15 vända sidan ej ända fram till det plan, som rymmer flikens/fliköro- nens inre plansida, utan är något smalare, varvid styrflänsarnas 16 hörnområde mellan delarna 15 och 17 lämpligen är utformat till en avfasning 19. Underkanten av öronen 18 kan vara något upplyft till en nivå ungefärligen med ovansidan av skänkeln 14 genom att vid stansning av ett ämne till ett fästdon anordnas urtag 20 mellan styrflänsarna 16 och öronen 18. Sådana spaltliknande urtag under- lättar även efterföljande bockningsoperationer.Immediately before the flap 15, mutually parallel guide flanges 16 are bent from both long sides of the short leg upwards at right angles upwards, the outer sides of which are suitably flush with the respective long sides of the legs 14 and 12, and whose side edges facing away from the flap are suitably drawn in the form of soft curves to become approximately at right level with the upper or free boundary edge of the flap at right angles to the shank 14 and end at a level such as 1 - 3 mm higher, where the guide flanges are bent at a right angle outwards to form multi-function ears 17 However, on the side facing the flap 15, these do not extend all the way to the plane which houses the inner plane side of the flap / flap, but are somewhat narrower, the corner area of the guide flanges 16 between the parts 15 and 17 being suitably formed into a chamfer 19. The lower edge of the ears 18 may be slightly raised to a level approximately with the top of the leg 14 by arranging a recess 20 between the guide flange when punching a blank to a fastener. the noses 16 and the ears 18. Such slit-like recesses also facilitate subsequent bending operations.

Såsom samtidigt framgår särskilt av fig 4, bildas mellan varje par öron 17, 18 på var sida om styrflänsparet 16 dels en ventikalt och dels en horisontellt genomgående styrspalt 21 resp 22. Bredden av dessa spalter, dvs i det ena fallet avståndet mellan öronens 17 fliknära kanter och flikens resp fliköronens inre plansida och i det andra fallet avståndet mellan öronens undersida och flikens/ fliköronens övre fria kant motsvarar ungefärligen tjockleken av skänklarna 5, medan avståndet mellan styrflänsarnas yttersidor un- gefärligen motsvarar bredden av slitsarna 6.As can be seen at the same time, in particular from Fig. 4, between each pair of ears 17, 18 on each side of the guide flange pair 16, a ventricular and a horizontally continuous guide gap 21 and 22, respectively, are formed. The width of these gaps, i.e. in one case the distance between edges and the inner plan side of the flap and flap ears, respectively, and in the second case the distance between the underside of the ears and the upper free edge of the flap / flap ears approximately corresponds to the thickness of the legs 5, while the distance between the outer sides of the guide flanges roughly corresponds to the width of the slots 6.

Ett så utformat fästdon 10 införes inifrån ett stativ e dyl 5 i en 10 _15 20 25 30 (TI __; C) Ä) ' l Cl 4 slits 6 med flerfunktionsöronen 17 främst och skänkeln 12 riktad nedåt, om det finns exempelvis vid övre änden av slitsen 6 en utvidgning av samma tillåtande sådan införing, exempelvis i något kantrat läge. Alternativt införes flerfunktionsöronen över varandra in och genom slitsen i dess längdled. Skänkeln 12 är då riktad åt sidan och kan användas som hävstång vid svängning till ett nedtill i fig 1 visat läge, varvid styrflänsarna 16 kommer att med ianspråkstagande av sin strukturelasticitet pressas något samman, så att det diagonalt sett avståndet från en styrflänssidokant till den andra jämfört med slitsbredden kan något större övervinnas. Efter passering av dödpunkten expanderar styrflänsarna åter och fästdonet intar nämnda läge, utifrån vilket det kan skjutas uppåt. Denna förskjutning är möjlig och begränsas även svängningsrörelsen av skänkeln 12 inåt i riktning mot stativmitten av styrspalterna 22, vilka resp vars begränsningsmedel bara tillåter, förutom godtyckliga mellanlägen, ett inre gränsläge, i vilket öronens 17 undersida anligger plant mot stativskänklarnas överkant anligger mot utsida, samtidigt som öronens 18 stativskänklarnas insida. I ett läge ungefärligen mitt på resp stativskänkel kan fästdonet lätt och enkelt med bara 1: ex en fingertippning svängas t ex ett kvarts varv utåt, så att den t ex bara med passningstolerans smalare skänkeln 12 och styrflänsarna kan passera genom slitsen 6 till skänkelns baksida. Denna utsvängningsrörelse hejdas, när stativskänkeln fyller ut den andra öronens 18 insida ligger an mot styrspalten 21, varvid stativskänklarnas insida, samtidigt som öronens 17 fliknära kanter är riktade mot stativskänklarnas utsida. Fästdonen intar då lägen, som visas i mitten av fig 1. Sedan pressas fästdonen nedåt genom att antingen med t ex ett finger gripa runt resp stativskänkel eller' medelst t ex ett ovanför fästdonet i slitsen 6 infört verktyg, tills fjäderfoten går mot t ex baksidan av tak- eller väggskivan 9. Eftersom skänklarna 12, 14 är strukturelastiskt fjädrande, kan man med ianspråkstagande av denna elasticitet fortsätta nedpressningsrörelsen av fästdonets infästningsände, samtidigt som skänklarna 12, 14 pressas isär och deras inre vinkel pressas även den vassa främre kanten av växer. Härvid 10 15 20 25 30 35 510 250 5 flerfunktionsöronen in i stativskänklarnas utsida, varigenom en oavsiktlig återgående fästdonsrörelse förhindras eller försvåras.A fastener 10 so designed is inserted from the inside of a frame or the like 5 into a slot 4 with the multifunction ears 17 in front and the leg 12 directed downwards, if there is for example at the upper end of the slot 6 an extension of the same permissible such insertion, for example in some tilted position. Alternatively, the multifunction ears are inserted over each other into and through the slot in its longitudinal direction. The leg 12 is then directed to the side and can be used as a lever when pivoting to a position shown at the bottom in Fig. 1, whereby the guide flanges 16 will be slightly compressed, claiming their structural elasticity, so that the diagonally spaced from one guide flange side edge to the other with the slot width, something larger can be overcome. After passing the dead center, the guide flanges expand again and the fastener assumes said position, from which it can be pushed upwards. This displacement is possible and also restricts the pivoting movement of the leg 12 inwards towards the frame center of the guide slits 22, which respective whose limiting means only allow, in addition to arbitrary intermediate positions, an internal limit position, in which the underside of the ears 17 abuts flat against the upper edge of the frame legs. as the inside of the 18 stand legs of the ears. In a position approximately in the middle of the respective frame leg, the fastener can be easily and simply swung outwards with only 1: eg a fingertip, for example a quarter turn, so that it can only pass through the narrower leg 12 and the guide flanges through the slot 6 to the back of the leg. This pivoting movement is stopped when the tripod leg fills the inside of the second ear 18 abutting against the guide gap 21, the inside of the tripod legs, at the same time as the flap-like edges of the ears 17 are directed towards the outside of the tripod legs. The fasteners then assume positions, which are shown in the middle of Fig. 1. The fasteners are then pressed downwards by either gripping the respective frame leg with one finger or by means of, for example, a tool inserted above the fastener in the slot 6, until the spring foot moves towards e.g. of the roof or wall panel 9. Since the legs 12, 14 are structurally resiliently, using this elasticity one can continue the depressing movement of the fastening end of the fastener, while the legs 12, 14 are pressed apart and their inner angle is also pressed the sharp front edge of waxes. In this case, the multifunction ears enter the outside of the frame legs, whereby an unintentional return of fastener movement is prevented or hindered.

Fästdonen drar samtidigt stativet längre in i öppningen 8 och basringens 7 företrädesvis tillbakavinklade stoppfläns pressas elastiskt mot väggskivan 9. En sådan fästförbindelse kan upphävas vid demontering exempelvis genom ett kraftigt slag med ett verktyg mot skänkeln 14 underifrån.At the same time, the fasteners pull the frame further into the opening 8 and the base ring 7's preferably angled stop flange is pressed elastically against the wall plate 9. Such a fastening connection can be canceled during disassembly, for example by a powerful blow with a tool against the leg 14 from below.

Uppfinningen är inte begränsad till ovan beskrivna och på bifogade ritningar visade utföranden, som kan modifieras och kompletteras på godtyckligt sätt inom ramen för uppfinningstanken, såsom den kommer till uttryck i följande patentkrav.The invention is not limited to the embodiments described above and shown in the accompanying drawings, which can be modified and supplemented in any way within the scope of the inventive concept, as it is expressed in the following claims.
