Telinetasojen tukikoukku. - Stodkrok for stållningsplan.Rack level support hook. - Management plan for the plan.

Keksinnon kohteena on tukikoukku telinetasoja vårten, joka koukku on muodostettu suulakepuristetusta kevytmetalliprofii-lista ja jossa koukussa on telinetason kannatinrakenteeseen kiinnitettåvå kiinnitysosa, telineen tasokannattimen (kanna-tinpalkki) tukihaaran påalla oleva tukiosa ja esiinpiståvån tukihaaran påålle tarttuva koukkuosa sekå kiinnitysosan, tuki-osan, ja koukkuosan våliin muodostettu alaspåin avoin ripustus-kita.The invention relates to a support hook for rack levels, which hook is formed from an extruded light metal profile and which has an attachment part to be attached to the support structure of the rack level, a support part on the support arm of the support part an internally formed downwardly open suspension gutter.

Telinetasoja vårten tunnetaan useita tukikoukkuja, jotka on muotoiltu kulloistakin telinejårjestelmaå vastaavasti ja jotka tåysin riittåvåsti ratkaisevat useita teknisiå tehtåviå. Eråis-så teknisisså yksityiskohdissa esiintyy kuitenkin ongelmia ja vaikeuksia.For scaffolding levels, a number of support hooks are known, which are designed according to the respective scaffolding system and which completely adequately solve several technical tasks. However, there are problems and difficulties in the technical details.

Keksinnon tehtåvåna on muotoilla telinetasojen tukikoukkuja siten, ettå koukut soveltuvat paremmin erittåin moninaisiin vaa-timuksiin, joita niille asetetaan. Tåmå tehtåvå on keksinnon mukaisesti ratkaistu siten ja keksinnon mukainen tukikoukku on tunnettu siita, ettå tukikoukun profiilissa on ristikkomainen jåykisterakenne, ettå tukikoukku on jårjestetty yhdistettåvåksi telinetason kannatinrakenteen kanssa tyontåmållå kiinnitysosa pitkittåispalkin sisåån, ja ettå koukun varsinaisen telinetason otsapååstå eniten ohitse ulottuva osa on vahvistettu aineska-saumalla ja ohjaamalla tukirivat kohti kiinnitysosan stabiileja alueita ja/tai kohti telinetason kannatinrakennetta.The object of the invention is to design the support hooks of the scaffold platforms in such a way that the hooks are better suited to the very diverse requirements placed on them. According to the invention, this object is solved in this way and the support hook according to the invention is characterized in that the support hook profile has a lattice-like stiffening structure, that the support hook is arranged to be connected to the and guiding the support ribs towards the stable areas of the fastening part and / or towards the support structure of the rack level.

DE-hakemusjulkaisusta 29 16 826 tunnetaan erilaisia tukikoukkuja, joilla on samankaltainen muotoilu. Julkaisu kåsittelee ennen kaikkea telinetasojen muita konstruktioelementtejå, mutta siinå on kuitenkin kuviossa 7 kevytmetallinen suulakepuristus-profiilin omaavat tukikoukut. Tukikoukut ulottuvat yhtenå yksittåisenå kappaleena poikittaisliitoselementin koko pituu- 2 91909 delle. Tållaisia låpimeneviå suulakepuristettuja profiileja voidaan soveltaa ainoastaan hyvin mååråttyihin tarkoituksiin telinetasoissa. Monissa kåyttosovellutuksissa vaaditaan yksit-tåisripustuskoukkuja, jotka sopivalla tekniikalla on jårjestet-ty sopiviin kohtiin. Viitejulkaisun selitysosan viimeisesså kappaleessa todetaan, ettå suulakepuristettu profiili voidaan katkoa lyhyiksi yksittåiskoukuiksi etusivun pituudelle jaetus-ti. Viitejulkaisussa ehdotetaan muutamaa, esim. neljåå nåin jaettua yksittåiskoukkua etusivun pituudelle jaetusti. Tållå ei kuitenkaan saavuteta mitåån etua niin kauan kuin koukkuja ei keksinnon mukaisesti tyonnetå pitkittåispalkin sisåån ja toi-saalta tållainen rakenne, joka viitejulkaisuissa on esitetty, ei kapeina koukkuina kestå ellei koukkuja ole vahvistettu keksinnon mukaisesti. Keksinnon mukaisessa ratkaisussa, esim. vii-tenumerolla 85 merkitty ontelo on oleellisesti pienempi kuin viitejulkaisun mukaisessa ratkaisussa, jolloin koukku myos on vastaavasti lujempi. Viitejulkaisun mukaisesta ratkaisusta puuttuu diagonaalituki, josta syystå sitå ei voida pitåå ris-tikkorakenteena. Diagonaalituen puuttumisen vuoksi ei myoskåån viitejulkaisun kuvion 7 aineskasaumilla ole lujuuden kannalta sitå merkitystå kuin keksinnon mukaisessa ratkaisussa, jossa aineskasaumat yhdesså diagonaalituen kanssa lujittavat raken-teen.DE-A-29 16 826 discloses various support hooks with a similar design. The publication mainly deals with other construction elements of scaffolding platforms, but in Figure 7 it nevertheless has support hooks with an alloy extrusion profile. The support hooks extend in one single piece over the entire length of the transverse connecting element 2 91909. Such through-extruded profiles can only be applied for well-defined purposes on scaffolding levels. Many applications require individual suspension hooks which are arranged in suitable places by suitable technology. The last paragraph of the explanatory part of the reference states that the extruded profile can be broken into short individual hooks divided by the length of the front side. The reference publication suggests a few, e.g., four, individual hooks divided in this way for the length of the front page. However, no advantage is achieved here as long as the hooks according to the invention are not pushed into the longitudinal beam and, on the other hand, such a structure as shown in the references does not last as narrow hooks unless the hooks are reinforced according to the invention. In the solution according to the invention, e.g. the cavity marked with the reference number 85, is substantially smaller than in the solution according to the reference publication, whereby the hook is also correspondingly stronger. The solution according to the reference publication lacks diagonal support, which is why it cannot be considered as a lattice structure. Due to the lack of diagonal support, the material joints of Fig. 7 of the reference publication also do not have the same significance in terms of strength as in the solution according to the invention, in which the material joints together with the diagonal support strengthen the structure.

Jos tukikoukun profiili muotoillaan varustettuna ristikkomai-sella jåykisterakenteella, voidaan paino pitåå niin pienenå kuin mahdollista ja siitå huolimatta tåytetåån hyvin erilaiset lujuusvaatimukset erittåin yksinkertaisella tavalla.If the profile of the support hook is shaped with a lattice-like stiffening structure, the weight can be kept as low as possible and nevertheless very different strength requirements are met in a very simple manner.

Påinvastoin kuin teråslevystå muodostetuissa tukikoukuissa on suulakepuristetun metalliprofiilin yhteydesså yksinkertaisem-malla tavalla enemmån mahdollisuuksia profiilin suhteen, kun halutaan mistå tahansa syystå enemmån metallista materiaalia mååråttyyn kohtaan, kuin mitå on mahdollista levystå muova-tuissa osissa. Levystå muovattujen osien yhteydesså voidaan ti 3 91909 periaatteessa ainoastaan hyvin suppeissa rajoissa muuttaa mate-riaalin seinåmåpaksuutta muovaamalla. Useimmat aineskasautumat esiintyvien voimien vastaanottamiseksi on aikaansaatava profi-loimalla ja muovaamalla, aikaansaamalla kaarevia pintoja, tait-tamalla kaksoislevyosia ja muulla vastaavalla tavalla. Tama asettaa muotoilumahdollisuuksille ja tarpeisiin sovittamiselle levymuoto-osien yhteydesså rajat, joita tåsså mielessa suulake-puristetuilla metalliprofiileilla ei ole.In contrast to steel hook support hooks, the extruded metal profile has, in a simpler way, more possibilities for the profile when, for whatever reason, more metallic material is desired at a given location than is possible in the molded parts of the sheet. In connection with the molded parts of the plate, ti 3 91909 can in principle only be changed within very limited limits by molding the wall thickness of the material. Most material accumulations to receive the forces present must be achieved by profiling and shaping, providing curved surfaces, folding double plate sections, and the like. This places limits on the design possibilities and adaptation to the needs in connection with the plate-shaped parts, which in this sense do not have extruded metal profiles.

Painon pitåmiseksi niin alhaisena kuin mahdollista ja korroo-siosuojavaatimusten tåyttåmiseksi ulkona ja tiloissa, joissa on korroosiota aiheuttavla osia ilmassa, nåhdaån tarkoituksenmu-kaiseksi, ettå tukikoukku on muodostettu suulakepuristetusta kevytmetalliprofiilista.In order to keep the weight as low as possible and to meet the corrosion protection requirements outdoors and in rooms with corrosive parts in the air, it is seen that the support hook is formed of an extruded light metal profile.

Kåytannon vaatimuksesta on otettava huomioon, ettå tukikoukut sovitetaan telinetasojen påihin ja ettå raa'assa kåytosså rakennuspaikoilla telinetasot asetetaan aina uudelleen maahan otsapinnan ylitse ulottuvine tukikoukkuineen, jolloin lisåksi telinetasoja voidaan pudottaa suurehkoista korkeuksista. Tål-loin tukikoukkuihin, joista myos kåytetåån nimitystå kynnet, kohdistuu suuria puskurasituksia. Tåmå voi johtaa kidan muo-donmuutokseen tai myos koukkuosan murtumiseen. Tåmån eståmi-seksi keksinnon erååsså tårkeåsså parannuksessa on jårjestetty siten, ettå tukikoukun eniten varsinaisen telinetason otsapåås-tå eniten ohitse ulottuva osa on vahvistettu aineskasaumalla ja tukiripojen stabiiliin kiinnitysosan ja/tai telinetason kanna-tinrakenteeseen suuntautuvan ohjauksen avulla. Tåtå tarkoitusta palvelee myos jo edellå esitetty toimenpide, ettå pååasialli-sesti esiintyvåt voimat vastaanotetaan sekå normaalista kuormi-tuksesta johtuvina ettå myos tdrmåyksestå aiheutuvina ristikko-rakennejårjestelmån toisiinsa liittyvån monitankokonstruktion avulla.The requirement for use must take into account that the support hooks are fitted to the ends of the scaffold platforms and that in raw use on construction sites the scaffold platforms are always re-placed on the ground with support hooks extending above the end surface, which can also be lowered from higher heights. Tål-loin support hooks, also called nails, are subjected to high buffer loads. This can lead to deformation of the gill or breakage of the hook part. To prevent this, in an important improvement of the invention it is provided that the part of the support hook extending most from the end of the actual rack plane end is reinforced by a material seam and by a stable fastening part of the support ribs and / or a support structure for the rack level guide. This purpose is also served by the measure already described above, that the forces mainly occurring are received both due to the normal load and also due to the collision by means of an interconnected multi-bar construction of the lattice structure system.

Eras tårkeå keksinnon nåkokohta on kidan etupuolella olevan koukkuosan ulko-osan muotoilu. Se on tarkoituksenraukaisesti siirretty taaksepåin tai viistottu koukun eniten ulkonevan osan suhteen, sopivimmin jatkuvasti sisåånpåin kulkevan linjan mukaisesti siten, ettå putoamisen yhteydesså ripustuskoukun kasaanpainumisen vaara huomattavasti våhenee. Tåmån lisåksi on mielekkåållå ripustuskoukun muotoilulla otettava huomioon toi-saalta ripustamisen tarpeet ja toisaalta telinetason hyvå koh-distus ja edelleen koukkuosan stabiilisuus. Tåtå vårten voidaan jårjeståå siten, ettå ripustuskita suppenee tukipintaa kohti ja erityisesti, ettå koukkuosa suppenee molemmilla sivuilla kohti ohjainkårkeåån. Nåin konstruktio on muotoiltu siten, ettå eniten kuormitettuihin tukikoukun ja kidan kohtiin on jårjestetty aineskasaumat, jotka kuitenkin myos valmistusteknisesti ovat helposti aikaansaatavissa ja eivåt toisaalta ole haitallisia koko profiilin ja valmiin tukikoukun muotoilun kannalta. Vaati-muksissa ja selitysosassa annetut mitat ovat tåsså tarkoituk-sessa erittåin merkittåviå.An important aspect of the invention is the design of the outer part of the hook part in front of the groove. It is expediently moved backwards or bevelled with respect to the most protruding part of the hook, preferably in a continuous inward line, so that the risk of the hanging hook collapsing in the event of a fall. In addition, the meaningful design of the hanging hook must take into account, on the one hand, the needs of the hanging and, on the other hand, the good alignment of the scaffold plane and further the stability of the hook part. In this way, it is possible to arrange the suspension cone tapering towards the support surface and, in particular, so that the hook part tapers on both sides towards the guide tip. In this way, the construction is designed in such a way that material joints are arranged at the most loaded parts of the support hook and the jaw, which, however, are also easily obtainable from the manufacturing point of view and are not detrimental to the design of the entire profile and the finished support hook. The dimensions given in the claims and in the explanatory note are very significant for this purpose.

Ristikkorakenne edesauttaa myos siten, ettå tukikoukku saadaan stabiilisti ankkuroitua telinetason kannatinrakenteeseen telinetason pitkittåispalkkiin sopivasti tyonnettåvån tyontotapin avulla, joka siirtåå erilaiset kuormitukset ja niistå aiheu-tuvat voimat muuten edullisen konstruktion yhteydesså tarkoi-tuksenmukaisesti telinetasoon. Tåtå edesauttavat yhdensuun-taiset ulkoseinåmåt, jotka ovat pitkittåispalkin ylåseinåmån ja alaseinåmån vieresså, sekå pystysuorasti ulottuvat tyontotapin osat ja ennen kaikkea tarkoituksenmukaisella tavalla sovitettu diagonaalituki, kuten yksityiskohtaisesti vaatimuksissa ja selitysosassa on esitetty.The lattice structure also facilitates that the support hook can be stably anchored to the scaffold support structure by means of a suitably inserted push pin which transmits various loads and the resulting forces in connection with an otherwise advantageous structure. This is facilitated by the parallel outer walls adjacent to the top and bottom walls of the longitudinal beam, as well as the vertically extending portions of the push pin and, above all, the appropriately arranged diagonal support, as detailed in the claims and the explanatory note.

Edelleen on mielekkåållå niittikiinnitysten sovituksella toisaalta våltettåvisså toisiinsa liitettåvien osien materiaalin • · 5 919C9 heikkeneminen ja toisaalta voimien johtaminen nåiden kohtien ohitse on toteutettavissa mielekkåållå tavalla, kuten vaatimuk-sissa ja selitysosassa on esitetty.It is further meaningful that the fitting of the rivet fastenings on the one hand avoids the weakening of the material of the parts to be connected to one another • · 5 919C9 on the other hand and the conduction of forces past these points can be implemented in a meaningful way, as stated in the claims and explanatory part.

Keksinnon muut edut, yksityiskohdat, tunnusmerkit ja nåkokohdat on esitetty myos muissa vaatimuksissa ja seuraavassa selitysosassa, jossa viitataan oheisiin piirustuksiin.Other advantages, details, features and aspects of the invention are set out in the other claims and in the following description, in which reference is made to the accompanying drawings.

Kuviossa 1 on telineestå esitetty ainoastaan pieni osa. Pylvååt 20 kannattavat telinejårjestelmån jakovåliå vastaavalla etåi-syydellå toisistaan sinånså tunnettuja reikålevyjå 21. Pylvåi-den 20 våliin on reikålevyihin 21 kiinnitetty liitåntåpåiden 30 avulla kannatinpalkki 22. Kannatinpalkki 22 on muotoiltu ylos-påin avoimeksi U-profiiliksi. Kannatinpalkin 22 pystysuorien • · 6 91909 haarojen 27.1 ja 27.2 ylåpååt on muodostettu tukireunoiksi 23 telinetason 26 tukikoukkuja 25.1, 25.2 ja 35 vårten. Liitån-tåpååt 30 on tunnetulla tavalla varustettu urilla ja tyonnetty reikålevyihin 21 ja varmistettu niihin kiiloilla 34. Tallå tai vastaavalla tavalla on toteutettu telineesså useita telineker-roksia. Edellå esitetty on otettu esiin ainoastaan sen vuoksi, ettå selvennettåisiin, kuinka keksinnon mukaiset tukikoukut lisåkkeineen on jårjestetty telinekokonaisuudessa.Figure 1 shows only a small part of the stand. The posts 20 support the spacing of the scaffolding system at a corresponding distance from each other in perforated plates 21 known per se. A support beam 22 is fastened to the perforated plates 21 by means of connecting ends 30. The support beam 22 is shaped open-up. The upper ends of the vertical branches 27.1 and 27.2 of the support beam 22 are formed as support edges 23 along the support hooks 25.1, 25.2 and 35 of the rack level 26. The connection ends 30 are provided with grooves in a known manner and are pushed into the perforated plates 21 and secured to them by wedges 34. Several rack layers are provided in the rack or in a similar manner. The above has been raised only in order to clarify how the support hooks according to the invention with their accessories are arranged in a scaffolding assembly.

Kuten kuviot 1 ja 2 osoittavat, on tåsså esimerkiksi valitussa telinetasossa 26 kolme tukikoukkua kullakin otsasivulla, joista koukuista molemmat ulommat koukut 25.1, 25.2 on kiinnitetty nurkkiin ja toisella tavoin muotoiltu tukikoukku 35 keskelle. Tukikoukku 35 on kiinnitetty telinetason tukirakenteen 37 poi-kittaispalkkiin 36 myohemmin esitettåvållå tavalla, sopivimmin hitsaamalla. Poikittaispalkki 36 on tåsså sovellutusesimerkisså hitsattu telinetason 26 tukirakenteen 37 molempien pitkittåis-palkkien 38.1 ja 38.2 våliin nurkkien kohdalla siten, ettå pit-kittåispalkkien katkaistut pååt 39.1 ja 39.2 jååvåt avoimiksi. Nåin aikaansaadaan mahdollisesti poikittaisjåykisteillå (ei esitetty) varustettu stabiili runko, joka muodostaa telinetason 26 tukirakenteen 37. Rungossa on - kuten kuviossa 5 ylhåållå esimerkiksi on esitetty - tukipinnat 41, jotka ulottuvat levey-delle noin 2/3 pitkittåispalkin profiilin leveydestå ja yltåvåt kulloinkin pystysuoraan kynteseinåmåån 42 saakka. Levyn 45 reu-na 43 asetetaan siihen. Levy 45 voi olla keittåmisen keståvåsti liimattua vaneria, jossa on liukastumisenestokerros, tai muuta, telineesså tavanomaista materiaalia. Sen pintana on telinetason 26 tyoskentelypinta 46. Niittien 47 avulla reuna 43 on sinånså tunnetulla tavalla niitattu kiinni.As shown in Figures 1 and 2, for example, in this selected rack level 26 there are three support hooks on each end side, of which both outer hooks 25.1, 25.2 are attached to the corners and the support hook 35 otherwise shaped in the middle. The support hook 35 is attached to the transverse beam 36 of the scaffold support structure 37 in the manner shown below, preferably by welding. In this application example, the transverse beam 36 is welded between the two longitudinal beams 38.1 and 38.2 of the support structure 37 of the scaffold plane 26 at the corners so that the cut ends 39.1 and 39.2 of the longitudinal beams remain open. This provides a stable frame, possibly with transverse stiffeners (not shown), which forms a support structure 37 for the rack level 26. The frame has - as shown in Figure 5 above, for example - support surfaces 41 extending about 2/3 of the width of the longitudinal beam profile and extending Up to 42. The edge 43 of the plate 45 is placed therein. The plate 45 may be a cooking-resistant glued plywood with a non-slip layer, or another material conventional in the rack. Its surface is the working surface 46 of the scaffold plane 26. By means of the rivets 47, the edge 43 is riveted in a manner known per se.

Keksinnon ensimmåiseksi esiin otettavan sovellutusmuodon mukaan tukikoukku 25 muodostuu kevytmetallisesta suulakepuristuspro-fiilin påtkåstå, jonka kokonaisrakenne ja yksityiskohdat ilme-. nevåt erityisesti kuvioista 3-5. Tålloin leikkauspinnat ti • · 91909 7 muodostavat tukikoukun sivupinnat 51.1 ja 51.2. Nåmå ovat vålin 52 pååsså toisistaan, joka våli mååråå tukikoukun paksuuden.According to a first embodiment of the invention, the support hook 25 consists of an alloy end of an extrusion profile, the overall structure and details of which are apparent. especially from Figures 3-5. In this case, the cutting surfaces ti • · 91909 7 form the side surfaces 51.1 and 51.2 of the support hook. These are spaced 52 apart from each other, which determined the thickness of the support hook.

Tåmå våli 52 on valittu siten, etta sivupintojen 51.1 ja 51.2 kohdat tyontotapiksi 50 muodostetussa kiinnitysosassa nojaavat sopivasti pitkittåispalkin 38.1 sisåseinåmåpinnan 53 ja kahden, tukikoukun 25 ohjausta vårten jårjestetyn sisapuolisen, alasei-nåmåsså 135 ja ylåseinåmåsså 136 olevan vasterivan 54.1 ja 54.2 vålisså. Sopivat niitit 57 on johdettu pitkittåispalkin 38 ulkoseinåmån ja tukikoukun 25 tyontotapin 50 låvitse ja kiinni-tetty tavanomaisella tavalla. Tatå vårten tukikoukkuun 25 on jårjestetty låpimenoaukot 51.1 ja 51.2 etåållå toisistaan ole-viin sopiviin kohtiin, kuten kuviosta 4 ilmenee. Låpimenoaukot 55.1 ja 55.2 on muodostettu kiinnityssilmukoihin 58.1 ja 58.2. Kiinnityssilmukka 58.2 on muodostettu takaylånurkkaan ylåsei-nåmån 56.2 ja takaseinåmån 56.3 våliin, jolloin låpimenoaukkoa 55.2 ympåroi suulakepuristetun kevytmetallin likimain yhtå suu-ri seinåmåpaksuus. Alaseinåmån 56.1, ylåseinåmån 56.2 ja takaseinåmån 56.3 seinåmåpaksuus 59 on noin 4 mm.This gap 52 is selected such that the points of the side surfaces 51.1 and 51.2 in the fastening part formed as the working pin 50 suitably rest on the inner wall surface 53 of the longitudinal beam 38.1 and the two inner 54 on the lower wall 135 and above the guide hook 25. Suitable rivets 57 are passed through the outer wall of the longitudinal beam 38 and the support pin 50 of the support hook 25 and fastened in a conventional manner. Thus, through-openings 51.1 and 51.2 are arranged in the remote support hook 25 at suitable locations at a distance from each other, as shown in Fig. 4. Passage openings 55.1 and 55.2 are formed in the fastening loops 58.1 and 58.2. A fastening loop 58.2 is formed in the rear corner between the top wall 56.2 and the rear wall 56.3, with the through hole 55.2 being surrounded by approximately equal wall thickness of the extruded light metal. The wall thickness 59 of the lower wall 56.1, the upper wall 56.2 and the rear wall 56.3 is about 4 mm.

Edempånå ja alaseinåmån 56.1 kohdalla oleva kiinnityssilmukka 58.1 on vålin 61 pååsså vastepinnasta 60. Vastepinta 60 on muodostettu holkkien avulla ja jårjestetty ylemmån sovitepinnan 62.2 tai alemman sovitepinnan 62.1 ja tåsså edullisesti vaaka-suorassa olevan tukiosan 65 ylårajan 63 tai sen alarajan 64 våliin, jolloin portaan tai olan korkeus vastaa likimain pitkittåispalkin 38.1 tai 38.2 seinåmån paksuutta, esimerkiksi noin 2,2 mm.

Taka-alanurkasta 66 alaseinåmån 56.1 ja takaseinåmån 56.3 vålistå kulkee diagonaaliuuma 67 vinosti eteen ylos, jonka uuman tarkka sijainti selostetaan tukiosan 65 selostuksen yhteydesså.From the rear lower corner 66, between the lower wall 56.1 and the rear wall 56.3, a diagonal web 67 runs obliquely upwards, the exact location of which web will be described in connection with the description of the support part 65.

Tukiosa 65 on pitkittåispalkin 38.1 tax 38.2 ulkopuolella eli sen pinnan edesså, joka muodostaa påån 39.1 tai 39.2 ja jota vasten tukikoukun 25 vastepinta 60 on tyonnetty. Tukiosa 65 sulkee tyontotapin 60 alaosasta pystyseinåmållå 68. Tåmå rajoittaa låpimenevån alemman tappitilan 69 etuosassa, jossa tilassa on pyoristetyt nurkat. Ulkopuolinen alempi pyoristys-pinta 71 låhtee alemmasta rajasta 64 ja jatkaa pystysuoraan, sisempaån ripustuskidan 70 kitaseinåmåån 72. Tåhån liittyy ylhåaltå sisåkiilapinta 73, joka ulottuu ripustuskidan 70 tukipintaan 75. Tukipinnalla 75 on leveys 76, joka on esimer-kiksi 6 mm. Ripustuskitaa 70 rajoittaa eteenpåin tukipinnan 75 vieressa kiilapinta 74, jolla on likimain sama, jyrkkå kallis-tus kuin kiilapinnalla 73. Kiilapinta 74 rajoittaa sisaånpåin koukkuosan 77 yhdessa ulkopuolisen, pystysuoran kitaseinamån 78 kanssa, joka seinama alhaalla muuttuu ohjainviisteeksi 79, johon puolestaan liittyy pyoristyksena alempi koukkupinta 80. Koukkuosaa 77 rajoittaa ulospåin alhaalta sisaånpåin kohti telinetasoa kallistettu koukkupinta 81, jolloin se ulottuu likimain tukipinnan 75 korkeudelle ja siella vaihtuu pystysuo-: raksi tukiosan 65 puskupinnaksi 82. Sen ja ylårajan 63 vålissa on ylempi puskupyoristys 83.The support part 65 is outside the longitudinal beam 38.1 tax 38.2, i.e. in front of the surface which forms the head 39.1 or 39.2 and against which the abutment surface 60 of the support hook 25 is pushed. The support portion 65 closes the push pin 60 from the lower portion by a vertical wall 68. This defines a through-going lower pin space 69 at the front where the space has rounded corners. The outer lower rounding surface 71 starts at the lower boundary 64 and continues vertically to the palate wall 72 of the inner suspension rail 70. This is joined at the top by an inner wedge surface 73 extending from the support surface 75 of the suspension rail 70. The support surface 75 has a width 76 of The suspension grate 70 is further limited adjacent to the support surface 75 by a wedge surface 74 having approximately the same steep inclination as the wedge surface 73. The wedge surface 74 in 80. The hook portion 77 is delimited outwardly from the bottom inwardly toward the rack plane by a hook surface 81 extending approximately to the height of the support surface 75 and thereby changing into a vertical butt surface 82 of the support portion 65. Between it and the upper limit 63 there is an upper butt barrier 83.

Tålloin pystysuora puskupinta 82 on vålin 84 paasså vastepinnan 60 etupuolella. Tåmå on suurin etåisyys vastepinnasta 60, joten tukikoukun 25 tormåtesså esteeseen tai telinetason 26 pudotessa pystysuorasti vasten tukikoukkua 25 pystysuora puskupinta 82 mahdollisesti yhdesså ylemmån puskupyoristyksen 83 kanssa ottaa vastaan. Tålloin koukkupinnan 81 kallistus on sellainen, ettå koukkuosa 77 mahdollisesti ei taivu sisaånpåin. Tåtå vårten on - kuten nåhdåån - tukipinnan 75 vieresså suuri materiaalikes- 919G9 9 kittymå ja tukiosan 65 ylåosa on sopivalla tavalla varustettu tukiosa-aukolla 85. Siinå on alhaalla, edesså viisto rajapinta 86, joka on tyontopaån 50 diagonaaliuuman 67 ylåseinåmån 87 jatkeella ja sitå rajoittaa muuten ulkopintojen kanssa likimain yhdensuuntaisesti ulottuvat seinåpinnat, kun taas sen pyoris-tettya sisåseinamåa 89 rajoittaa liitosuuma 90 tukiosan 65 ja ripustustapin 50 vålisså. Liitosuumalla 90 on tappitilan 95 puolella kaareva seinåmåpinta 96, joka vahitellen vaihtuu ylåseinåmån 56.2 alarajapinnaksi. Kiinnityssilmukka 58.2 on nur-kassa ylåseinåmån 56.2 ja takaseinåmån 56.3 rajapintojen vålis-så ylemmåsså tappitilassa 95. Liitosuuma 90 vaihtuu solmukoh-daksi 91, joka tuen ripustuskidan 70 ohella vastaanottaa tuki-osaan 65 vaikuttavat voimat ja johtaa ne kolmeen uumaan, nimit-tåin pystyseinåmåån 68, diagonaaliuumaan 67 sekå liitosuumaan 90 ja ylåseinåmåån 56.2. Tåmån solmukohdan 91 etupuolella on ripustuskidan ulkopuolella tukivahvike 92, jota - kuten nåhdåån - rajoittavat kuvatut, vinosti ulottuvat pinnat ja joka erityi-sesti vaikuttaa tukiosan 55 stabiilisuuteen ilman, ettå seinå-mån paksuuserot tulisivat liian suuriksi. Tamå mahdollistaa valmistuksen sopivilla tekniikoilla, erityisesti kevytmetallin suulakepuristusmenetelmån.In this case, the vertical buffer surface 82 is spaced 84 in front of the abutment surface 60. This is the greatest distance from the abutment surface 60, so that when the support hook 25 crashes into an obstacle or when the rack level 26 falls vertically against the support hook 25, the vertical buffer surface 82 possibly together with the upper buffer abutment 83 receives. In this case, the inclination of the hook surface 81 is such that the hook part 77 may not bend inwards. Thus, as can be seen, adjacent the support surface 75 there is a large material center 919G9 9 and the upper part of the support part 65 is suitably provided with a support part opening 85. It has a lower, oblique interface 86 at the front, which is in the upper wall of the diagonal web 67 otherwise wall surfaces extending approximately parallel to the outer surfaces, while its rounded inner wall 89 is bounded by a joint 90 between the support portion 65 and the suspension pin 50. The connecting fume 90 has a curved wall surface 96 on the side of the pin space 95, which gradually changes to the lower interface of the upper wall 56.2. The fastening loop 58.2 is at an angle in the upper pin space 95 between the interfaces of the top wall 56.2 and the rear wall 56.3. , to the diagonal web 67 and to the joint 90 and to the top wall 56.2. In front of this node 91 there is a support reinforcement 92 outside the suspension rail, which - as can be seen - is limited by the described obliquely extending surfaces and which in particular affects the stability of the support part 55 without the wall thickness differences becoming too great. This enables manufacture by suitable techniques, in particular the light metal extrusion process.

Etåisyys 84 on sopivimmin 32 mm, kun taas tukipinta 75 on vålin 63 paåsså ylårajan 63 alapuolella, jolloin tåma våli 93 on sopivimmin 20 mm, kun taas koukkuosa 77 on alimpaan kårkeenså 80 mitattuna noin 24 mm pitkå. Koukun kokonaispituus 94 tyonto-tappeineen 50 on noin 92 mm suositussa sovellutusmuodossa. Eri-tyisen edullista on, ettå diagonaaliuuma 67 muuttuu solmukohdan låvitse nåennåisesti suorana jatkeena samoin diagonaalisesti ulottuvaksi elementiksi tukivahvikkeeseen 92 ja siten johtaa pystysuoraan puskupintaan 82 vaikuttavat voimat tyontotapin 50 alempaan takanurkkaan 66 siten, ettå koko tukikoukku 25 - kuten nåhdåån - on muodostettu ristikkomaiseksi ja ottaa siten edul-lisesti vastaan sekå taivutusvoimia ettå myos puskuvoimia koko-naisuudessaan ja siirtåå voimat kiinnityssilmukoiden 58.1 ja 10 91909 58.2 kautta niihin liittyvien niittien 57 avulla tai vastepin-nan 60, paiden 39.1 ja 39.2 avulla tai sovitepintojen 62.1 ja 62.2 avulla pitkittåispalkkiin 38.1 tai 38.2 siten, ettå kaik-kia kåytånnon tarpeita vastaava muoto on saavutettu, joka muoto mahdollistaa erityisen helpon valmistettavuuden ja asennuksen, koska suulakepuristettu profiili on ainoastaan katkaistava, tyonnettåva paikalleen ja niitattava.The distance 84 is preferably 32 mm, while the support surface 75 is at a distance 63 below the upper limit 63, this distance 93 being preferably 20 mm, while the hook portion 77 is about 24 mm long as measured at its lowest point 80. The total length 94 of the hook 94 with the push pin 50 is about 92 mm in the preferred embodiment. It is particularly advantageous that the diagonal web 67 transforms through the node as a seemingly straight extension as well as a diagonally extending element into the support reinforcement 92 and thus conducts the forces acting on the vertical buffer surface 82 to the lower rear corner 66 preferably against both bending forces and also the pushing forces in their entirety and transmitting the forces through the fastening loops 58.1 and 10 91909 58.2 by means of associated rivets 57 or by abutment surface 60, shirts 39.1 and 39.2 or by adapter surfaces 62.1 and 62.2 to longitudinal beam 38.1 or 38.2 thus, that a shape that meets all the needs of the application is achieved, which makes it particularly easy to manufacture and install, since the extruded profile only has to be cut, pushed into place and riveted.
