i DK 166630 B1in DK 166630 B1
Opfindelsen angår en holdemekanisme for et stillads-element, der ikke er anbragt i en lodret stilling, eksempelvis en stilladsbund, en vandret tværstang eller en diagonalstiver, indeholdende mindst én, ved enden placeret klo, som 5 oppefra griber over en vandret bærerigel og har en nedefter vendende, åben bærerigelåbning, samt en affjedret spærreklinke, der er lejret i et klo-hus, og som er svingelig og indrettet til at forhindre en utilsigtet frahægtning, hvilken klinke i indgrebsstillingen ved hjælp af én spærrende endedel 10 angriber bæreriglen neden under horisontalmidten.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a holding mechanism for a scaffolding element which is not positioned in a vertical position, for example a scaffolding bottom, a horizontal cross bar or a diagonal strut, containing at least one end claw located at the top which grips a horizontal support bar from the top and has a downwardly facing open carrier opening, as well as a resilient locking latch mounted in a claw housing, which is pivotal and arranged to prevent an unintentional locking, which latch in the engagement position by means of one locking end portion 10 engages the carrier below the horizontal center.
Sådanne bæremekanismer er omhandlet i DE-Gebrauchs-muster nr. 71 28 051 og svejtsisk patentskrift nr. 542 793, og er kendt under betegnelsen indgrebskloer. I den i reglen anvendte udførelsesform er spærreklinken foran bærerigelåb-15 ningen placeret noget ovenfor denne. Herved får bevægelsescirklerne for endepunkterne af bæreriglens indgrebsflader en position, som under spærreklinkens svingning opefter uden videre frigiver indgrebsforbindelsen. På den anden side angriber bæreriglens indgrebsflade under en nedefter 20 rettet tilbagesvingningsbevægelse neden under rørets hori-zontalmidte. Herved forhindres en løftning af stilladselementet, medmindre spærreklinken betjenes. Sådanne spærreklinker kan også være udstyret med en yderligere, fra klinken udragende næse til bevægelse af klinken i åbningsretningen, 25 så at man ikke behøver at tage fat i den ende af organet, som ligger umiddelbart ved siden af den vandrette bærerigel. Herved undgås faren for, at betjeningspersonens finger kan komme i klemme.Such support mechanisms are disclosed in DE-Gebrauchs patterns No. 71 28 051 and Swiss Patent Specification No. 542 793, and are known by the term engraving claws. In the embodiment used as a rule, the locking latch in front of the carrier opening is located slightly above it. In this way, the circles of movement of the end points of the engaging surfaces of the support latch get a position which, during the swinging of the locking link upwards, freely releases the engagement connection. On the other hand, the engaging surface of the support latch attacks under a downwardly directed backward movement below the horizontal center of the tube. This prevents lifting of the scaffolding element unless the locking lever is operated. Such barrier latches may also be provided with an additional nose extending from the latch for movement of the latch in the opening direction so that one does not have to grasp the end of the member which is adjacent to the horizontal support rail. This avoids the danger of the operator's finger getting caught.
I de nævnte trykskrifter er tilbageføringsfjederen 30 udformet som en trykfjeder. Praktiske udførelsesformer for sådanne holdemekanismer har imidlertid i reglen en dreje-fjeder, der er viklet omkring spærreklinkens drejetap, og hvis kraft er således afpasset, at den på den ene side understøtter spærreklinkens af klinkens egenvægt fremkaldte 35 nedfaldsbevægelse, og på den anden side tilvejebringer en tilbageføringskraft, der forhindrer en utilsigtet åbning, DK 166630 B1 2 men som under montagearbejdet ikke er særlig trættende for montagepersonalet.In said printing presses, the return spring 30 is designed as a pressure spring. However, practical embodiments of such holding mechanisms generally have a pivot spring wound around the pivot of the latch, and whose force is so adapted as to support, on the one hand, the latch movement induced by the latch's weight, and on the other provides a recoil force that prevents an unintended opening, but which during assembly work is not very tiring for the assembly personnel.
Sådanne holdemekanismer anvendes især til montering af stilladsbunde, som er ophængt imellem to bærerigler.In particular, such holding mechanisms are used for mounting scaffold bottoms which are suspended between two support bars.
5 Skal en stilladsbund monteres, er den ved spærreklinken virksomme tilbageføringskraft uden større betydning, fordi en enkelt montør først kan lægge bundens ene ende på den ene bærerigel eller endda allerede hægte den i indgrebsforbindelse med riglen, og derefter kan svinge bundens anden 10 ende nedefter og lade klinken udføre en svingningsbevægelse imod fjederens tilbageføringskraft.5 If a scaffolding bottom is to be mounted, the retracting force exerted by the ratchet is of no importance, because a single installer can first place one end of the base on one support bolt or even already hook it in engagement with the bolt, and then the other end of the base can swing downwards and allow the latch to perform a pivotal movement against the spring return force.
Vil man imidlertid demontere stilladsbunden, medfører de kendte holdemekanismer alvorlige vanskeligheder, hvorfor demonteringen hidtil kun kan gennemføres af to personer i 15 fællesskab. Hvis man nemlig løfter stilladsbundens ene ende under tilbageføring af spærreklinken fra indgrebsstillingen og fasthæftningsforbindelsen, og forsøger at støtte bundens ende løst på spærreklinkens kant for derefter at løfte bundens anden, i en afstand på mindst to meter beliggende ende, 20 så vil stilladsbundens vægt i reglen trykke spærreklinken atter tilbage, hvorved bærerigelåbningerne lægger sig over bæreriglen, og spærreklinkerne atter falder i spærrestilling. Det er derfor for nærværende ikke muligt at lade en enkelt person gennemføre demonteringen.However, if the scaffold floor is to be dismantled, the known holding mechanisms cause serious difficulties, and so far the dismantling can only be carried out by two people in 15 communities. Namely, if one lifts one end of the scaffold while returning the locking latch from the engagement position and the attachment connection, and tries to support the bottom end loosely on the edge of the latch and then lift the other bottom, at a distance of at least two meters, then the weight of the scaffolding will generally push the locking lever back again, whereby the carrier latches overlie the carrier latch and the locking latches again fall into the locking position. Therefore, it is not currently possible to have a single person complete the dismantling.
25 Formålet med opfindelsen er at udforme holdemekanismen på en sådan måde, at den ved en enkel betjening gør det muligt, at det pågældende stilladselement kan demonteres alene af en enkeltperson, således at i det mindste en ende af stilladselementet også i dettes frahægtede stilling kan 30 støtte løst på den vandrette bærerigel.The object of the invention is to design the holding mechanism in such a way that it enables, by a simple operation, that the scaffold element in question can be dismantled only by an individual, so that at least one end of the scaffold element can also be disposed in its detached position. support loosely on the horizontal carrier.
Dette opnås ifølge opfindelsen ved, at spærreklinkens yderste, nedre spærreende neden under sin med bæreriglen samvirkende flade er udstyret med en støttefordybning, der er tilpasset efter bæreriglens radius eller profilform, og 35 at den ved den spærrende endedel virksomme tilbageføringskraft, som hidrører fra tilbageføringsfjederens fjederkraft, DK 166630 B1 3 er således afpasset efter stilladselementets vægt, at den bærer stilladselementet, uden at der fremkaldes en indgrebsforbindelse.This is achieved according to the invention in that the outermost, lower locking end of the locking latch beneath its surface cooperating with the support latch is provided with a support groove adapted to the radius or profile shape of the latch and that the return force exerted by the locking spring spring arising from the spring spring Thus, DK 166630 B1 3 is adapted to the weight of the scaffolding element so that it carries the scaffolding element without eliciting an engagement connection.
Den på spærreklinken anbragte støttefordybning gør 5 det muligt, at den ende af det pågældende stilladselement, som af den demonteringen udførende person er blevet løftet fri, efter tilbagestillingen af spærreklinken kan lægges med denne støttefordybning på den vandrette bærerigel med en løs, men veldefineret positionering. Ved en afpasning af 10 fjederens kraft efter vægten af det pågældende stilladselement sikres, at spærreklinken ikke svinges utilsigtet tilbage med det resultat, at bærerigelåbningen atter griber over den vandrette bærerigel og spærreklinken atter bevæges tilbage i spærrestilling. Når nævnte ene ende nu med sikkerhed 15 støttes i den fritløftede position, kan den demontagen gennemførende person gå til den forholdsvis fjernt liggende anden ende af elementet og på dette sted løsne spærreklinken og frahægte stilladslemenetet og derefter, fordi elementet nu med sikkerhed er helt frigivet, fjerne elementet og trans-20 portere det til aflægningspladsen. Ved anvendelse af denne meget enkle, men efffektive yderligere foranstaltning på spærreklinken, som opnås uden nævneværdige fremstillingsomkostninger, og alene muliggøres ved en snedig formgivning af spærreklinkens ende, opnås en ganske væsentlig forbedring 25 af demonteringsprocessen. I denne forbindelse er det hensigtsmæssigt, at der mellem den med bæreriglen samvirkende flade og støttefordybningen findes en meget skråtstillet mellemflade for at opnå, at spærreenden bliver tilstrækkelig stabil, at støttefordybningen kan udformes i en passende 30 position i forhold til bæreriglen, og at der tilvejebringes en passende udformning af anlægskanten, som tillader, at spærreklinken ved et tryk oppefra på den pågældende ende af stilladselementet kan svinges tilbage, og indgrebskloen kan hægtes på. For at undgå slitage på bæreriglerne og på kloen 35 som følge af hyppige manipulationer af denne art er sådanne spærreklinker allerede i lang tid, og i afvigelse fra den i DK 166630 Bl 4 de førnævnte trykskrifter omhandlede måde, blevet fremstillet af et fladt stykke plademateriale med profileret formstofbe-klædning. Herved kan man på enkel måde ændre fladekonturen og også uden større produktionsforanstaltninger give påvirk-5 nings- og støttefladerne en passende bredde.The support recess positioned on the locking clamp allows the end of the scaffolding element in question, which has been lifted free by the dismantling person, after the resetting of the locking clamp can be laid with this support recess on the horizontal support bolt with a loose but well-defined positioning. By adjusting the force of the spring by the weight of the scaffold element concerned, it is ensured that the locking latch is not inadvertently pivoted back, with the result that the carrier opening engages again over the horizontal support rail and the locking lever is again moved into the locking position. When said one end is now securely supported in the free-raised position, the disassembly carrying person may go to the relatively distant other end of the element and at this point loosen the locking latch and disengage the scaffold body and then, because the element is now fully released, remove the element and transport it to the deposition site. Applying this very simple but effective additional measure to the ratchet latch, which is obtained at no significant manufacturing cost, and made possible only by a cunning design of the latch end, provides quite a substantial improvement in the disassembly process. In this connection, it is desirable that there exists a very inclined intermediate surface between the surface cooperating with the support groove to obtain that the locking end becomes sufficiently stable that the support groove can be formed in a suitable position with respect to the support groove and that it is provided. a suitable configuration of the abutment edge which allows the locking latch to be pivoted back at a pressure from above on the relevant end of the scaffolding element and the locking claw can be hooked on. In order to avoid wear on the carrier bars and on the claw 35 as a result of frequent manipulations of this kind, such barriers have been manufactured for a long time, and in deviation from the manner described in DK 166630 Bl 4, a flat piece of sheet material with profiled plastic lining. In this way, one can easily change the surface contour and, without major production measures, give the impact and support surfaces an appropriate width.
Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, på hvilken fig. 1 viser et skematisk snit igennem en udførelsesform for en stilladssektion ifølge opfindelsen med påhægtet 10 stilladsbund, fig. 2 et enkelt holdeelement i påhægtet tilstand, samt de i elementhusets indre skjult anbragte konstruktions-elementer, fig. 3 et billede svarende til fig. 2, men uden at 15 vise de skjult anbragte indre konstruktionselementer, og fig. 4 et billede svarende til fig. 3, i hvilken delene er frahægtet og afstøttet.The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 shows a schematic section through an embodiment of a scaffold section according to the invention with a hooked scaffold bottom 10; FIG. 2 shows a single retaining element in the closed state, as well as the structural elements arranged in the inner housing of the element housing; FIG. 3 is a view similar to FIG. 2, but without showing the hidden inner structural members; and FIG. 4 is a view similar to FIG. 3, in which the parts are detached and supported.
Stilladset 10 har stolper eller rammer 11, som er udstyret med vandrette bærerigler 12. En del af en diago-20 nalstiver 13 er antydet.The scaffold 10 has posts or frames 11 which are equipped with horizontal support bars 12. A portion of a diagonal strut 13 is indicated.
Stilladsbunden 14 har ved hver af sine ender to indgrebskløer 15, hvis bærerigelåbninger 16 vender nedefter, og på sædvanlig måde er skudt over bæreriglerne 12. Bærer iglerne 12 er udformet som cylindriske, fortrinsvis af letmetal 25 bestående rør. De kan også være profilerede elementer og i enhver udformning også bestå af stål.The scaffold bottom 14 has two engagement claws 15 at each end thereof, whose support groove openings 16 face downwards, and in the usual manner are shot over the support bars 12. The carrier gules 12 are formed as cylindrical, preferably of light metal 25 tubes. They can also be profiled elements and in any design also consist of steel.
Stilladsets bund 14 kan være udformet i enhver sædvanlig art og eksempelvis bestå af en rammekonstruktion med en pålagt plade, som helt igennem er udformet af stålplade-30 materiale, eller som er en af flere materialer sammensat konstruktion. Bunden 14 har fastgørelsesender 17, hvori husene 18 for indgrebskiøerne 15 er fastgjort. Husene 18 er udformet som bukkede og profilerede, ved udstansning og bukning fremstillede pladedele, fortrinsvis af stål, og 35 delene er forsynet med et korrosionsbeskyttende overfladelag, eksempelvis et zinklag. Husenes yderste, nedre ende har en DK 166630 B1 5 afrundet slutnæse 19. Midtpunktet, henholdsvis midteraksen af låseriglen 12 og låserigelåbningen 16 er betegnet med 20.The base 14 of the scaffold can be formed in any conventional kind and, for example, consist of a frame structure with an applied plate which is entirely formed of steel plate material or which is a structure composed of several materials. The bottom 14 has attachment ends 17 in which the housings 18 for the engagement islands 15 are secured. The housings 18 are formed as bent and profiled sheet metal parts made of punching and bending, preferably steel, and the parts are provided with a corrosion-protective surface layer, for example a zinc layer. The outermost, lower end of the housings has a DK 166630 B1 5 rounded end nose 19. The center, respectively, the center axis of the locking latch 12 and the latching opening 16 are designated 20.
En spærreklinke 21 er i huset 18's indre på sædvanlig måde svingeligt lejret på en bæretap 22, der rager igennem 5 huset 18. I forhold til stilladsbunden 14 er bæretappen 22 anbragt foran låserigelåbningen 16 og placeret noget oven for denne. Spærreklinken 21 har den især i fig. 2 anskuelig-gjorte form med et antal forstærkningsribber 23, der rager frem fra en midterste, flad del. Klinken er fortrinsvis 10 fremstillet i den viste form af et ved sprøjtestøbning formgivet plastmateriale, hvorhos der i midterplanet er inkorporeret en til formen svarende del af et fladt plademateriale. Klinken kan også bestå af andre materialer, eksempelvis et egnet metaltrykstøbningsmateriale, eller være udformet 15 som et af stål smedet legeme. Spærreklinken 21 har en anslagsende 24, som strækker sig udover det ved bæretappen 22 tilstedeværende leje og støtter sig således på den inderste forvæg 25, at spærreklinken 21 kun rager meget lidt ind i bærerigelåbningen 16, når der i denne ikke ligger nogen 20 bærerigel. Herved kan spærreklinken 21 åbnes automatisk ved en nedtrykning. En tilbageføringsfjeder 26 er på den viste måde udformet som en drejefjeder, således som det allerede har været anvendt ved de hidtil kendte spærreklinker, men på den for opfindelsen ejendommelige måde er fjederen 26's 25 kraft nu dimensioneret på en særlig måde, således som det skal forklares nærmere i det følgende.A locking latch 21 is pivotally mounted in the interior of the housing 18 on a support pin 22 which projects through the housing 18. Relative to the scaffold base 14, the support pin 22 is positioned in front of the locking opening 16 and located slightly above it. The locking latch 21, especially in FIG. 2 is an illustrated form with a plurality of reinforcing ribs 23 projecting from a middle, flat portion. The latch is preferably made in the illustrated form of injection molded plastics material, wherein a portion of a flat sheet material corresponding to the mold is incorporated in the center plane. The latch may also consist of other materials, for example a suitable metal pressure casting material, or be formed as a steel forged body. The latch 21 has a stop end 24 which extends beyond the bearing present at the support pin 22 and so rests on the inner front wall 25 that the latch 21 extends very little into the carrier opening 16 when there is no 20 carrier latch. Hereby, the locking latch 21 can be opened automatically by a depression. In the illustrated manner, a return spring 26 is designed as a pivot spring, as has already been used in the prior art latches, but in the manner of the invention, the power of spring 26 is now dimensioned in a particular way, as will be explained. in the following.
Spærreklinken 21*s nederste spærreende 27 har i sit indre en afrundet påvirkningsflade 28 for bæreriglen. Denne flade har samme radius som bæreriglen 12, og den er placeret 30 neden under bæreriglen 12's, henholdsvis bærerigelåbningen 16's vandrette midterplan 29. Som vist spærrer den i indgrebsstillingen på sædvanlig måde. Den frigives, når spærreklinken 21 trykkes opad mod tilbageføringsfjederen 26's kraft. Til lettelse af opadtrykningen findes der på ydersiden 35 en næse 31, som man kan tage fat på.The lower latch 27 of the latch 21 * has in its interior a rounded impact surface 28 for the carrier latch. This surface has the same radius as the carrier bolt 12, and it is positioned 30 below the carrier center 12 of the carrier bolt 12, respectively, the horizontal median plane 29. As shown, it locks in the engagement position in the usual manner. It is released when the latch 21 is pressed upward against the force of the return spring 26. To relieve the upward pressure, there is a nose 31 on the outside 35 which can be gripped.
I væsentlig afstand neden under påvirkningsfladen 28 DK 166630 B1 6 for bæreriglen er en støttefordybning 30 udformet som en delcylinderflade med en størrelse svarende til spærreklinkens hele bredde, til hvilket formål der findes randbenene 34 på begge sider af spærreklinkens midterribbe. Fra påvirknings-5 fladen 28 for bæreriglen strækker sig en forholdsvis stejlt placeret mellemflade 33 frem til støttefordybningen 30, dels for at bringe støttefordybningen i en passende position, og dels for imellem fordybningen og den afrundede næse 19 at skabe et gab, som i det væsentlige svarer til bæreriglen 10 12, så at man kan trykke indgrebskloen 15 i indgrebsstilling også ved en tilsvarende kraft og et passende anlæg.At a substantial distance below the bearing surface 28 DK 166630 B1 6 for the support bolt, a support recess 30 is formed as a sub-cylinder surface having a size corresponding to the entire width of the locking latch, for which purpose the edge legs 34 are located on both sides of the middle rib of the locking latch. From the support surface 28 of the support groove, a relatively steeply located intermediate surface 33 extends to the support recess 30, partly to bring the support recess into a suitable position, and partly between the recess and the rounded nose 19 to create a gap which substantially corresponds to the carrier latch 10 12, so that the engagement claw 15 can be pressed into engagement position also by a corresponding force and a suitable system.
Som det fremgår af fig. 4, kan nu hele stilladsbunden med sin ene ende støttes fritliggende på bæreriglen 12, idet de fra den lodrette midte bagud i retning mod stil-15 ladsbunden 14 ragende støttefordybninger 30 foroven hviler løst, men sikret mod en lettere forskydning, hvis spærreklinkerne 21 i forvejen ved hjælp af næsen 31 er blevet løftet og svinget tilbage i hvilestillingen. Nu kan samme person foretage frahægtningsoperationen ved stilladsbundens 20 modsatte ende, og derefter kan stilladsbunden tages ned. Tilbageføringsfjedrene 26's kraft er derfor således dimensioneret, at den på støttefordybningen 30 virkende støttekraft under hensyntagen til de på tegningen anskueliggjorte vægtstangsforhold er tilstrækkelig til at bære den pågældende 25 andel af vægten af stilladsbunden 14, eller af et andet stilladselement. På den anden side er de dog således dimensioneret, at spærreklinken 21 kan tilbagesvinges manuelt.As shown in FIG. 4, the entire scaffold bottom can now be supported with one end exposed on the carrier 12, with the support recesses 30 protruding from the vertical center backwards towards the stylus bottom 14 resting loosely, but secured against a slight displacement if the locking latches 21 in advance by the nose 31 has been lifted and swung back into the resting position. Now, the same person can perform the capping operation at the opposite end of the scaffold floor 20, and then the scaffold floor can be taken down. Therefore, the force of the return springs 26 is dimensioned such that the support force acting on the support groove 30, taking into account the bar-rod conditions illustrated in the drawing, is sufficient to carry the relevant proportion of the weight of the scaffold base 14, or of another scaffold element. On the other hand, however, they are dimensioned such that the locking latch 21 can be reversed manually.
Ved hver ende 17 af stilladsbunden 14 findes der på begge sider med en afstand på ca. 33, 50, 60 eller 70 cm to 30 sådanne indgrebskløer. I princippet er det tilstrækkeligt at anbringe spærreklinker 21 kun ved den ene ende på den her omhandlede måde, fordi man kun behøver at støtte én ende.At each end 17 of the scaffolding base 14 there are on both sides with a distance of approx. 33, 50, 60 or 70 cm to two such claws. In principle, it is sufficient to place barrier latches 21 only at one end in the manner contemplated here because one end only needs to be supported.
Man kan imidlertid også anbringe samme spærreklinker ved den anden ende, for at kunne gennemføre en frigivelse af 35 låseforbindelsen, og en understøtning ved hver ende. Spærreklinkerne vil generelt også kunne anvendes ved andre stil- DK 166630 Bl 7 ladselementer, såsom diagonalstivere, vandrette rigler, eller endda ved påklemning fastholdte sidedele, såfremt noget sådant måtte være formålstjenligt. Fremstillingsomkostningerne er ringe, nye byggeelementer er ikke nødvendige, 5 og alligevel opnås der en væsentlig manipulerings-fordel.However, the same locking latches may also be provided at the other end to enable release of the locking connection and a support at each end. The latches can generally also be used for other style elements, such as diagonal struts, horizontal bars, or even clamped side portions, if any such may be appropriate. Manufacturing costs are low, new building elements are not necessary, and yet a significant manipulation benefit is obtained.
Det væsentlige for opfindelsen er således følgende:Thus, the essentials of the invention are the following:
En holdemekanisme er udformet som en indgrebsklo 15, der har en bærerigelåbning 16. Denne er åben nedefter.A holding mechanism is designed as an engagement claw 15 having a support opening 16 which is open downward.
Til åbningen hører en på en tap 22 lejret spærreklinke 21.To the opening is a locking latch 21 mounted on a pin 22.
10 Denne har en støttefordybning 30, der gør det muligt, at indgrebskloen i frigivet tilstand kan støttes løst på bæreriglen 12, for at lette stilladsets demontering.This one has a support groove 30 which enables the engaging claw in the released state to be loosely supported on the carrier 12, to facilitate the scaffold removal.
