Description

Die Erfindung betrifft eine Halteeinrichtung für ein nicht-vertikales Gerüstelement, insbesondere einen Gerüstboden, einen Horizontalriegel oder einen Diagonalriegel, mit wenigstens einer am Ende vorgesehenen, von oben über einen horizontalen Tragriegel greifenden Klaue mit einer nach unten offenen Tragriegel-Öffnung und mit einer in einem Klauengehäuse gelagerten, schwenkbaren, unbeabsichtigtes Aushängen verhindernden, im Einrastzustand unterhalb der Horizontalmitte am Tragriegel mit einem Sperr-Ende angreifenden, gefederten Sperrklinke.The invention relates to a holding device for a non-vertical scaffolding element, in particular a scaffolding floor, a horizontal bar or a diagonal bar, with at least one claw provided at the end and extending from above over a horizontal support bar with a downwardly open support bar opening and with one in one Claw housing mounted, swiveling, unintentional unhooking, in the locked state below the horizontal center on the support bolt with a locking end attacking spring pawl.

Derartige Halteeinrlchtungen sind in DE-GM 71 28 051 = CH-PS 542 973 behandelt und werden als Einrastklauen bezeichnet. Die Sperrklinke ist bei der zumeist ver­wendeten Ausführungsform vor der Tragriegelöffnung etwas oberhalb derselben gelagert. Dadurch erhalten die Bewegungskreise der Tragriegel-Angriffsflächen-Endpunkte eine Lage, die beim Verschwenken der Sperrklinke nach oben die Rastung ohne weiters freigibt. Andererseits greift bei Rückschwenkung nach unten die Tragriegel-Angriffsfläche unterhalb der Horizontalmitte des Rohres an. Dadurch wird das Hochheben des Gerüstelementes ohne Betätigung der Sperrklinke verhindert. Derartige Sperrklinken können auch mit einer zusätzlich von der Sperrklinke wegragenden Nase zum Betätigen derselben in Öffnungsrichtung ausgestattet sein, damit man nicht an dem Ende anfassen muß, welches unmittelbar neben dem horizontalen Tragriegel liegt. Dadurch wird die Gefahr des Einklemmens des Fingers vermieden.Such holding devices are dealt with in DE-GM 71 28 051 = CH-PS 542 973 and are referred to as snap claws. The pawl is mounted in the mostly used embodiment in front of the support bolt opening somewhat above it. As a result, the movement circles of the support bar engagement surface end points are given a position which, when the pawl is pivoted upwards, readily releases the catch. On the other hand, when pivoting backwards, the support bar engagement surface below the horizontal center of the tube attacks. This prevents the scaffolding element from being raised without actuating the pawl. Such pawls can also be equipped with a nose protruding from the pawl for actuating the same in the opening direction, so that one does not have to touch the end which is located directly next to the horizontal support bar. This avoids the risk of the finger becoming trapped.

In den vorgenannten Druckschriften ist die Rückstellfeder als Druckfeder ausgeführt. Praktische Ausführungsformen solcher Halteeinrichtungen haben in der Regel jedoch eine um den Gelenkbolzen der Sperrklinke gewickelte Drehfeder, die in ihrer Kraft so abgestimmt ist, daß sie einerseits das Herunterfallen der Sperrklinke infolge ihres Eigen­gewichts gut unterstützt und andererseits eine Rückstell­ kraft aufbringt, die ein unbeabsichtigtes Öffnen verhindert, bei der Montage jedoch für das Bedienungs­personal nicht zu ermüdend ist.In the aforementioned publications, the return spring is designed as a compression spring. However, practical embodiments of such holding devices generally have a torsion spring wound around the hinge pin of the pawl, the force of which is so matched that on the one hand it supports the falling of the pawl well as a result of its own weight and on the other hand a reset force that prevents unintentional opening, but is not too tiring for the operating personnel during assembly.

Solche Halteeinrichtungen werden insbesondere an Gerüstböden verwendet, die zwischen zwei Tragriegeln eingehängt sind. Wenn man den Gerüstboden montieren will, ist die an der Sperrklinke wirksame Rückstellkraft ohne größere Bedeutung, weil eine einzelne Montageperson das eine Ende des Gerüstbodens zunächst auf den einen Tragriegel auflegen oder auch schon einrastend einhängen kann und dann das andere Ende herunterschwenken und gegen die Rückstellkraft der Feder die Klinke verschwenken lassen kann.
Will man jedoch den Gerüstboden demontieren, so ergeben sich mit den herkömmlichen Halteeinrichtungen beträcht­liche Schwierigkeiten, so daß die Demontage bisher nur von zwei Personen vorgenommen werden kann. Hebt man nämlich das eine Ende des Gerüstbodens unter Zurückstellen der Sperrklinken aus der Verrastung und Einhängung und versucht, es lose auf der Kante der Sperrklinke abzustützen, um dann das andere, in mindestens 2 m Abstand liegende Ende des Gerüstbodens anzuheben, so drückt das Gewicht des Gerüstbodens in der Regel die Sperrklinken wieder zurück und die Tragriegelöffnungen legen sich über den Tragriegel und die Sperrklinken fallen wieder in die Sperrstellung. Deshalb ist Ein-Mann-Demontage derzeit nicht möglich.Such holding devices are used in particular on scaffolding floors that are suspended between two support bars. If you want to assemble the scaffolding floor, the restoring force effective on the pawl is of no great importance, because a single assembler can first place one end of the scaffolding floor on one of the support bolts or even snap it in and then swivel the other end down and against the restoring force of the Spring can pivot the pawl.
However, if you want to dismantle the scaffolding floor, there are considerable difficulties with the conventional holding devices, so that the dismantling has so far only been possible for two people. If you lift one end of the scaffolding floor while putting the pawls back out of the catch and hooking and try to loosely support it on the edge of the pawl, in order to then raise the other end of the scaffolding floor, which is at least 2 m apart, the weight of the Scaffolding floor, the pawls usually back and the support bolt openings lie over the support bolt and the pawls fall back into the locking position. Therefore, one-man dismantling is currently not possible.

Hier setzt nun die Erfindung ein und hat sich zur Aufgabe gestellt, die Halteeinrichtung so auszugestalten, daß sie es bei leichter Betätigung gestattet, das Gerüstelement mit einer Person zu demontieren und dabei auch in ausgehängter Stellung wenigstens ein Ende des Gerüstelementes lose auf dem horizontalen Tragriegel abzustützen.This is where the invention comes in and has set itself the task of designing the holding device in such a way that, with slight actuation, it allows the scaffolding element to be dismantled by one person and, in the unhooked position, to loosely support at least one end of the scaffolding element on the horizontal support bar .

Erfindungsgemäß ist vorgesehen, daß das äußere, untere Sperr-Ende der Sperrklinke unterhalb seiner Tragriegelangriffsfläche mit einer dem Radius oder der Profilgestaltung des Tragriegels angepaßten Abstützvertiefung ausgestattet ist, und daß die am Sperrende wirksame, aus der Kraft der Rückstellfeder resultierende Rückstellkraft auf das Gewicht des Gerüstelementes derart abgestimmt ist, daß sie das Gerüstelement ohne Einrasten trägt.According to the invention it is provided that the outer, lower locking end of the pawl below its support bar engagement surface is equipped with a support recess adapted to the radius or the profile design of the support bar, and that the effective restoring force resulting from the force of the return spring on the weight of the scaffolding element is coordinated so that it carries the scaffolding element without snapping.

Die zusätzlich an der Sperrklinke vorgesehene Abstütz­vertiefung gestattet es nunmehr das von einer Demontage­person ausgehobene Ende des jeweiligen Gerüstelementes nach Rückstellen der Sperrklinke mit dieser Abstützvertiefung auf dem horizontalen Tragriegel lose, jedoch definiert aufzulegen. Infolge der Abstimmung der Kraft der Feder auf das jeweilige Gewicht des Gerüstelementes ist sicherge­stellt, daß die Sperrklinke auch nicht unbeabsichtigt zurückgeschwenkt wird und damit die Tragriegelöffnung wieder über den horizontalen Tragriegel greift und die Sperrklinke wieder in die Sperrstellung zurückbewegt wird. Wenn so das eine Ende mit Sicherheit in der ausgehobenen Stellung abgestützt ist, kann die Demontageperson an das relativ weit entfernt liegende andere Ende des Gerüst­elementes gehen und dort die Sperrklinke lösen und das Gerüstelement aushängen und dann - weil es nun mit Sicherheit im ganzen frei ist - wegnehmen und der Ablage zuführen. Durch die verblüffend einfache, zusätzliche Maßnahme an der Sperrklinke, die ohne nennenswerten Herstellungsaufwand nur durch geschickte Formgebung des Endes der Sperrklinke ermöglicht wird, erzielt man eine Demontageverbesserung von beträchtlichem Ausmaß. Dabei ist es zweckmäßig, daß zwischen dem Ende der Tragriegel-­Angriffsfläche und der Abstützvertiefung eine stark geneigte Zwischenfläche vorgesehen ist, damit das Sperrende ausreichend Stabilität erlangt und andererseits die Abstützvertiefung in geeigneter Lage zu dem Tragriegel ausgebildet werden kann und andererseits eine geeignete Anlagekantengestaltung zustande kommt, die es gestattet, die Sperrklinke durch Drücken von oben auf das betreffende Ende des Gerüstelementes zurückzuschwenken und die Einrastklaue einzuhängen. Damit bei solchen häufig wieder vorkommenden Vorgängen Abnutzungen an den Tragriegeln und der Klaue nicht zu groß werden, werden derartige Sperrklinken schon seit langem in Abweichung von der in den vorgenannten Druckschriften behandelten Art aus einem Flachblechteil mit profilierter Kunststoff- Umspritzung hergestellt. Durch diese Kunststoff-Umspritzung ist es in einfacher Weise möglich die Flächengestalt zu ändern und den Angriffs- und Abstützflächen auch ohne zu großen Herstellungsaufwand die geeignete Breite zu geben.The additional support recess provided on the pawl now allows the end of the respective scaffold element raised by a disassembly person to be loosely but definedly placed on the horizontal support bar after the pawl has been reset with this support recess. As a result of the coordination of the force of the spring with the respective weight of the scaffold element, it is ensured that the pawl is not inadvertently swiveled back and thus the support bolt opening reaches over the horizontal support bolt again and the pawl is moved back into the locked position. If one end is securely supported in the raised position, the disassembly person can go to the relatively far away other end of the scaffolding element and release the pawl there and unhook the scaffolding element and then - because it is now safely free as a whole - remove and bring to the shelf. The astonishingly simple, additional measure on the pawl, which is made possible without any noteworthy manufacturing effort only by skillful shaping of the end of the pawl, leads to a considerable improvement in disassembly. It is expedient that a strongly inclined intermediate surface is provided between the end of the support bar engagement surface and the support recess so that the locking end attains sufficient stability and on the other hand the support recess can be formed in a suitable position with respect to the support bolt and on the other hand a suitable contact edge design is achieved, which allows the pawl to be pivoted back onto the relevant end of the scaffolding element by pressing from above and to hook in the locking claw. So that wear on the support bolts and the claw does not become too large in such frequently occurring processes, such pawls have long been made in one departure from the type discussed in the aforementioned documents Flat sheet metal part made with molded plastic extrusion. This plastic encapsulation makes it possible to change the surface shape in a simple manner and to give the attacking and supporting surfaces the suitable width even without too much production effort.

Das Gerüst 10 hat Stiele oder Rahmen 11, die mit horizontalen Tragriegeln 12 ausgestattet sind. Eine Diagonalstrebe 13 ist teilweise angedeutet.The scaffold 10 has stems or frames 11 which are equipped with horizontal support bars 12. A diagonal strut 13 is partially indicated.

Ein Gerüstboden 14 hat an seinen beiden Enden je zwei Einrastklauen 15, deren Tragriegelöffnungen 16 nach unten offen sind und über die Tragriegel 12 gesteckt sind, wie es üblich ist. Die Tragriegel 12 sind als zylindrische Rohre, insbesondere aus Leichtmetall, ausgebildet. Sie können auch profilierte Elemente sein und in jeder Form ggf. auch aus Stahl bestehen.A scaffolding floor 14 has two latching claws 15 at both ends, the support bolt openings 16 of which are open at the bottom and are inserted over the support bolts 12, as is customary. The support bars 12 are designed as cylindrical tubes, in particular made of light metal. They can also be profiled elements and can also be made of steel in any shape.

Der Gerüstboden 14 kann in jeder üblicher Art ausgebildet sein, z. B. aus einer Rahmenkonstruktion mit Auflageplatte bestehen, im ganzen aus Stahlblech geformt oder in einer Konstruktion aus mehreren Materialien aufgebaut sein. Der Gerüstboden 14 hat Befestigungsenden 17, in denen die Gehäuse 18 der Einrastklauen 15 befestigt sind. Die Gehäuse 18 sind als gebogene und profilierte Stanz- und Biege-Blechteile, vorzugsweise aus Stahl, ausgebildet und mit einer korrosionsschützenden Oberflächenbeschichtung versehen, beispielsweise verzinkt. Das äußere, untere Ende hat eine gerundete Endnase 19. Der Mittelpunkt bzw. die Mittelachse von Tragriegel 12 und Tragriegelöffnung 16 ist mit 20 bezeichnet.The scaffolding floor 14 can be designed in any conventional manner, for. B. consist of a frame construction with a platen, formed entirely from sheet steel or constructed in a construction of several materials. The scaffolding floor 14 has fastening ends 17 in which the housings 18 of the latching claws 15 are fastened. The housings 18 are designed as bent and profiled stamped and bent sheet metal parts, preferably made of steel, and are provided with a corrosion-protective surface coating, for example galvanized. The outer, lower end has a rounded end nose 19. The center or the central axis of the support bar 12 and support bar opening 16 is designated 20.

Die Sperrklinke 21 ist im Innern des Gehäuses 18 auf einem Lagerbolzen 22, der das Gehäuse 18 durchdringt, in konventioneller Weise schwenkbar gelagert. Der Trag­bolzen 22 ist bezüglich des Gerüstbodens 14 vor der Tragriegelöffnung 16 und etwas oberhalb derselben angeordnet. Die Sperrklinke 21 hat die insbesondere aus Fig.2 ersichtliche Gestalt mit mehreren Verstärkungs­rippen 23, die von einem mittleren Flachteil aus wegragen. Sie ist vorzugsweise als mit Kunststoff im Spritzgußverfahren in der ersichtlichen Form gebildetes Bauteil gestaltet, wobei in der Mittelebene ein der Form entsprechendes Flachblechteil eingespritzt ist. Sie kann auch aus anderen Werkstoffen bestehen, beispiesweise einem geegneten Metall-Druckguss oder als Stahlschmiedeteil ausgebildet sein. Die Sperrklinke 21 hat ein Anschlag­ende 24, welches sich über die Lageranordnung beim Tragbolzen 22 hinaus erstreckt und an der inneren Vorderwand 25 so abstützt, daß die Sperrklinke 21 nur ganz geringfügig in die Tragriegelöffnung 16 hineinragt, wenn kein Tragriegel darin liegt. So kann die Sperrklinke 21 automatisch durch Niederdrücken geöffnet werden. Eine Rückstellfeder 26 ist als Drehfeder in der ersichtlichen Weise ausgebildet, wie es schon bisher bei bekannten Sperrklinken dieser Art üblich war, jedoch ist in erfindungsgemäßer Weise nunmehr die Kraft der Feder 26 in besonderer Weise dimensioniert, wie es im folgenden weiter erläutert werden wird.The pawl 21 is pivotally mounted in the interior of the housing 18 on a bearing pin 22 which penetrates the housing 18 in a conventional manner. The support bolt 22 is in relation to the scaffold floor 14 in front of the support bolt opening 16 and somewhat above the same arranged. The pawl 21 has the shape shown in particular in Figure 2 with several reinforcing ribs 23 which protrude from a central flat part. It is preferably designed as a component formed with plastic by injection molding in the form shown, a flat sheet metal part corresponding to the shape being injected in the central plane. It can also consist of other materials, for example, a die-cast metal die-cast part or a steel forged part. The pawl 21 has a stop end 24 which extends beyond the bearing arrangement at the support pin 22 and is supported on the inner front wall 25 so that the pawl 21 projects only very slightly into the support bolt opening 16 when there is no support bolt therein. Thus, the pawl 21 can be opened automatically by pressing it down. A return spring 26 is designed as a torsion spring in the manner shown, as was previously customary in known pawls of this type, but the force of the spring 26 is now dimensioned in a special manner in the manner according to the invention, as will be explained in the following.

Das untere Sperrende 27 der Sperrklinke 21 hat im Innern die gerundete Tragriegel-Angriffsfläche 28. Sie hat den gleichen Radius wie der Tragriegel 12 und liegt unterhalb der Horizontalmittelebene 29 des Tragriegels 12 bzw. der Tragriegelöffnung 16. Wie ersichtlich, sperrt sie in der eingerasteten Stellung in üblicher Art. Durch Hochdrücken der Sperrklinke 21 gegen die Kraft der Rückstellfeder 26 wird sie freigegeben. Zur Erleichterung des Hochdrückens ist außen eine Nase 31 vorgesehen, an der man anfassen kann.The lower locking end 27 of the pawl 21 has the rounded support bolt engagement surface 28 inside. It has the same radius as the support bolt 12 and is below the horizontal central plane 29 of the support bolt 12 or the support bolt opening 16. As can be seen, it locks in the engaged position in the usual manner. By pushing the pawl 21 against the force of the return spring 26, it is released. To facilitate pushing up a nose 31 is provided on the outside, which you can touch.

In beträchtlichem Abstand unterhalb der Tragriegel-­Angriffsfläche 28 ist eine Abstützvertiefung 30 als Teilzylinderfläche von der ganzen Breite der Sperrklinke ausgebildet, wozu die Randschenkel 34 beiderseits des Mittelsteges der Sperrklinke vorgesehen sind. Vom Ende 32 der Tragriegel-Angriffsfläche 28 erstreckt sich eine relativ steil liegende Zwischenfläche 33 bis zur Abstützvertiefung 30, um einerseits die Abstützvertiefung in eine geeignete Lage zu bringen und andererseits zwischen ihr und der gerundeten Endnase 19 ein Maul zu schaffen, welches in etwa dem Tragriegel 12 entspricht, so daß man die Einrastklaue 15 auch mit entsprechender Kraft und entsprechender Anlage in die Einraststellung drücken kann.At a considerable distance below the support bar engagement surface 28, a support recess 30 is formed as a partial cylinder surface of the entire width of the pawl, for which purpose the edge legs 34 are provided on both sides of the central web of the pawl. A relatively steep intermediate surface 33 extends from the end 32 of the support bar engagement surface 28 to the support recess 30, on the one hand to bring the support recess into a suitable position and on the other hand to create a mouth between it and the rounded end nose 19, which roughly corresponds to the support bolt 12 corresponds, so that you can press the locking claw 15 with the appropriate force and appropriate system in the locked position.

Wie Fig. 4 zeigt, kann nunmehr der ganze Gerüstboden mit seinem einen Ende frei auf dem Tragriegel 12 aufliegend abgestützt werden, indem nämlich die von der Vertikalmitte nach hinten in Richtung auf den Gerüstboden 14 reichenden Abstützvertiefungen 30 oben lose, jedoch gegen leichtes Verschieben gesichert aufliegen, wenn die Sperrklinken 21 zuvor mit Hilfe der Nase 31 ausgehoben wurden und in die Ruhestellung zurückgeschwenkt sind. Nunmehr kann am anderen Ende des Gerüstbodens das Aushängen von derselben Person vorgenommen werden und dann kann man den Gerüstboden abnehmen. Die Kraft der Rückstellfedern 26 ist dabei so ausgelegt, daß unter Berücksichtigung der aus den Zeichnungen ersichtlichen Hebelverhältnisse die auf die Abstützvertiefung 30 wirkende Stützkraft ausreicht, um den jeweiligen Anteil des Gewichtes des Gerüstbodens 14 oder eines sonstigen Gerüstelementes zu tragen. Andererseits ist sie jedoch so dimensioniert, daß man die Sperrklinke 21 von Hand zurückschwenken kann.As shown in FIG. 4, the entire scaffold floor can now be supported with one end lying freely on the support bar 12, namely by the support recesses 30 extending from the vertical center towards the back towards the scaffold floor 14 lying loosely on top, but secured against easy displacement if the pawls 21 were previously lifted using the nose 31 and into the Rest position are pivoted back. Now the same person can unhook at the other end of the scaffolding floor and then you can remove the scaffolding floor. The force of the return springs 26 is designed so that, taking into account the lever ratios shown in the drawings, the supporting force acting on the support recess 30 is sufficient to support the respective proportion of the weight of the scaffolding floor 14 or another scaffolding element. On the other hand, however, it is dimensioned such that the pawl 21 can be pivoted back by hand.

An jedem Ende 17 des Gerüstbodens 14 sind auf beiden Seiten im Abstand von etwa 33, 50, 60 oder 70 cm liegend zwei derartige Einrastklauen vorgesehen. Es reicht grund­sätzlich, wenn an nur einem Ende Sperrklinken 21 in der hier dargestellten Form vorgesehen sind, weil man nur ein Ende abzustützen braucht. Man kann jedoch dieselben Sperrklinken auch am anderen Ende vorsehen, um die Ent­riegelung und Abstützung auf jedem Ende vornehmen zu können. Auch kann man die Sperrklinken generell für andere Gerüstelemente verwenden, wie Diagonalstäbe, Horizontal­riegel oder sogar seitliche Anklemmungen, wenn dieses sinnvoll ist. Der Fertigungsaufwand ist gering, neue Bauteile werden nicht benötigt, trotzdem wird ein großer Handhabungsvorteil erzielt.At each end 17 of the scaffold floor 14 two such latching claws are provided lying on both sides at a distance of approximately 33, 50, 60 or 70 cm. It is basically sufficient if pawls 21 in the form shown here are provided at only one end, because one end only needs to be supported. However, the same pawls can also be provided at the other end in order to be able to unlock and support each end. You can also generally use the pawls for other scaffolding elements, such as diagonal bars, horizontal bars or even lateral clamps, if this makes sense. The manufacturing effort is low, new components are not required, but a great handling advantage is achieved.
