- a working platform preferably a scaffold for scaffolding or the like, with stands arranged in parallel to one another, which are connected in a ladder-like manner by crossbeams (bars), in which the platforms are fastened at their narrow end faces, open at the bottom and hooks provided with lifting safeguards can be hung on crossbars at the same height.
- lateral support tubes bearing covering plates are provided with downward-facing hooks at their ends, which overlap the crossbeams or crossbars and which are provided with locking pins under spring tension for locking them to the crossbars.
- a known from DE-OS 39 23 815 working platform of the type mentioned has platforms that are provided at their ends with hooks that overlap the crossbars or crossbars of the scaffold.
- the hooks of cross members on the foot side or so-called "foot bolts” are overlapped by the stand sections which extend and which are plugged onto the lower stand sections in such a way that they cannot unhook.
- this configuration only allows a platform to be unhooked when the corresponding stand sections are taken away with the foot latch, so that the hooks and with them the platform can disengage from the head latches.
- the crossbars overlapping, rounded hooks of the platforms are each provided on the hook base with a nose which engages under the crossbars.
- the platforms can only be unhooked in an oblique direction, so that the end-side planks must be fixed on the last crossbars in order to lock the planks.
- the platforms can be released by tensile forces acting on one end of the working platform, it has been provided according to DE-PS 29 52 538 that the hooks on the crossbars are locked by bolts to be used in particular.
- the object of the invention is to provide a working platform of the type mentioned, in which the platforms can be locked in a simple manner on the crossbeams of the stand in such a way that they can be lifted again at any time as required can be without having to dismantle other parts of the work platform or scaffolding.

- the hooks supporting the platforms on the crossbeams or crossbeams are locked to the crossbeams in that a pivoting and / or displaceable locking plate on the guide engages behind the crossbeam in the locking position with a nose, the locking position by one in a vertical position Is secured towards movable wedge, which moves automatically into its locking position due to the action of gravity. If the work platform or the scaffolding is subject to vibrations or movements, the locking of the hook connections only becomes firmer because the locking wedge immediately slides more firmly into its locking position if there should be a play loosening the locking.
- the lock according to the invention can be released in a simple manner by lifting the locking wedge, so that the individual platforms can be lifted again at any time as required, without further parts of the working platform or the scaffolding having to be dismantled. Since the Locking wedges automatically slip into their locking position after hooking the platforms onto the crossbars, a self-locking retention of the platforms is guaranteed. It is particularly advantageous that the platforms can be installed and removed again without special tools.
- both plates are guided on a common bolt in elongated holes.
- the outer plate provided with the locking lug need only be provided with a bore of such a diameter or length that it can pivot at least between its locking position and its release position. This is because the outer locking plate can only get into its locked and unlocked position by pivoting or by pivoting while simultaneously executing a movement in its longitudinal direction.

Abstract
Description
Die Erfindung betrifft eine Arbeitsbühne, vorzugsweise ein Gerüst zur Einrüstung von Fassaden o. dgl., mit parallel zueinander angeordneten Ständern, die durch Quertraversen (Riegel) miteinander leiterartig verbunden sind, bei der die Plattformen durch an deren schmalen Stirnseiten befestigte, nach unten offene und mit Abhebsicherungen versehene Haken auf auf gleicher Höhe befindliche Quertraversen einhängbar sind.The invention relates to a working platform, preferably a scaffold for scaffolding or the like, with stands arranged in parallel to one another, which are connected in a ladder-like manner by crossbeams (bars), in which the platforms are fastened at their narrow end faces, open at the bottom and hooks provided with lifting safeguards can be hung on crossbars at the same height.
Bei Arbeitsbühnen und Gerüsten dieser Art besteht die Forderung, daß diese möglichst schnell und einfach aufgebaut und auch wieder abgebaut werden können, wobei sichergestellt sein muß, daß die auf die Quertraversen eingehängten Plattformen nicht unbeabsichtigt durch Stöße von unten oder durch Einwirkung von Wind gelöst und abgehoben werden können.In the case of working platforms and scaffolding of this type, there is a requirement that these can be assembled and dismantled as quickly and easily as possible, it being necessary to ensure that the platforms suspended on the crossbars are not inadvertently released and lifted by impacts from below or by the action of wind can be.
Es sind zahlreiche Arbeitsbühnen der eingangs angegebenen Art mit unterschiedlichen Abhebsicherungen für deren Plattformen bekannt.Numerous work platforms of the type mentioned at the outset with different lifting safeguards for their platforms are known.
Bei einer aus der DE-OS 23 58 000 bekannten Arbeitsbühne der eingangs angegebenen Art sind seitliche, Belagplatten tragende Stützrohre an ihren Enden mit abwärts gerichteten Haken versehen, die die Quertraversen oder Querriegel übergreifen und die zu ihrer Verriegelung an den Querriegeln mit unter Federspannung stehenden Verriegelungsstiften versehen sind.In a work platform of the type specified at the outset in DE-OS 23 58 000, lateral support tubes bearing covering plates are provided with downward-facing hooks at their ends, which overlap the crossbeams or crossbars and which are provided with locking pins under spring tension for locking them to the crossbars.
Eine aus der DE-OS 39 23 815 bekannte Arbeitsbühne der eingangs angegebenen Art weist Plattformen auf, die an ihren Enden mit Haken versehen sind, die die Quertraversen oder Querriegel des Gerüsts übergreifen. Um ein unbeabsichtigtes Abheben der Plattformen zu vermeiden, werden die Haken von fußseitigen Quertraversen oder sogenannten "Fußriegeln" von die Ständer verlängernden Ständerabschnitten, die auf untere Ständerabschnitte aufgesteckt werden, in der Weise übergriffen, daß diese nicht aushaken können. Diese Ausgestaltung gestattet es jedoch erst, eine Plattform auszuhaken, wenn die entsprechenden Ständerabschnitte mit dem Fußriegel wegenommen werden, so daß die Haken und mit ihnen die Plattform außer Eingriff mit den Kopfriegeln kommen können.A known from DE-OS 39 23 815 working platform of the type mentioned has platforms that are provided at their ends with hooks that overlap the crossbars or crossbars of the scaffold. In order to avoid unintentional lifting of the platforms, the hooks of cross members on the foot side or so-called "foot bolts" are overlapped by the stand sections which extend and which are plugged onto the lower stand sections in such a way that they cannot unhook. However, this configuration only allows a platform to be unhooked when the corresponding stand sections are taken away with the foot latch, so that the hooks and with them the platform can disengage from the head latches.
Bei einer aus der DE-PS 29 16 236 bekannten Arbeitsbühne der eingangs angegebenen Art sind die Querriegel übergreifenden, abgerundeten Haken der Plattformen jeweils an der Hakenbasis mit einer Nase versehen, die die Querriegel untergreift. Auf diese Weise lassen sich die Plattformen nur in schräger Richtung aushaken, so daß zum Verriegeln der Dielen die endseitigen Dielen an den letzten Querriegeln festgelegt werden müssen. Da sich jedoch gezeigt hat, daß sich die Plattformen durch an einem Ende der Arbeitsbühne angreifende Zugkräfte lösen lassen, ist nach der DE-PS 29 52 538 vorgesehen worden, daß die Haken an den Querriegeln durch besonders einzusetzende Bolzen verriegelt werden.In a work platform of the type specified at the outset of DE-PS 29 16 236, the crossbars overlapping, rounded hooks of the platforms are each provided on the hook base with a nose which engages under the crossbars. In this way, the platforms can only be unhooked in an oblique direction, so that the end-side planks must be fixed on the last crossbars in order to lock the planks. However, since it has been shown that the platforms can be released by tensile forces acting on one end of the working platform, it has been provided according to DE-PS 29 52 538 that the hooks on the crossbars are locked by bolts to be used in particular.
Aufgabe der Erfindung ist es, eine Arbeitsbühne der eingangs angegebenen Art zu schaffen, bei der sich die Plattformen in einfacher Weise an den Quertraversen der Ständer in der Weise ver riegeln lassen, daß sie nach Bedarf jederzeit auch wieder ausgehoben werden können, ohne daß weitere Teile der Arbeitsbühne oder des Gerüsts abgebaut werden müssen.The object of the invention is to provide a working platform of the type mentioned, in which the platforms can be locked in a simple manner on the crossbeams of the stand in such a way that they can be lifted again at any time as required can be without having to dismantle other parts of the work platform or scaffolding.
Erfindungsgemäß wird diese Aufgabe bei einer Arbeitsbühne der gattungsgemäßen Art dadurch gelöst, daß jede Abhebsicherung aus in vertikaler Richtung gegeneinander verschieblichen Elementen oder Platten besteht, von denen die äußere, der Quertraverse zugewandte Platte an ihrem unteren Endbereich mit einer diese formschlüssig hintergreifenden Nase versehen und mindestens die innere Platte keilförmig ausgebildet ist, und daß beide Platten an an der Stirnseite der Plattform vorgesehenen Führungen derart geführt sind, daß die äußere Platte in ihrer unteren und/oder ausgeschwenkten Stellung die Quertraverse mit ihrer Nase hintergreift und die innere, unmittelbar oder mittelbar auf der Stirnseite abgestützte Platte in ihrer unteren Stellung die äußere Platte in ihrer Verriegelungsstellung verspannt. Bei der erfindungsgemäßen Arbeitsbühne sind die die Plattformen auf den Querriegeln oder Quertraversen abstützenden Haken dadurch mit den Quertraversen verriegelt, daß eine auf der Führung schwenkbar und/oder verschiebbare Verriegelungsplatte die Quertraverse in der Verriegelungsstellung mit einer Nase formschlüssig hintergreift, wobei die Verriegelungsstellung durch einen in vertikaler Richtung verschieblichen Keil gesichert ist, der sich selbsttätig aufgrund Schwerkraftwirkung in seine Verriegelungsstellung bewegt. Unterliegt die Arbeitsbühne oder das Gerüst Erschütterungen oder Bewegungen, wird die Verriegelung der Hakenverbindungen nur fester, weil der Verriegelungskeil sofort fester in seine Verriegelungsstellung rutscht, wenn sich ein die Verriegelung lockerndes Spiel ergeben sollte. Die erfindungsgemäße Verriegelung läßt sich in einfacher Weise durch Anheben des Verriegelungskeils lösen, so daß sich die einzelnen Plattformen jederzeit nach Bedarf wieder ausheben lassen, ohne daß weitere Teile der Arbeitsbühne oder des Gerüsts abgebaut werden müßten. Da die Verriegelungskeile nach dem Einhaken der Plattformen auf die Querriegel von selbst in ihre Verriegelungsstellung rutschen, ist eine selbstsichernde Halterung der Plattformen gewährleistet. Von besonderem Vorteil ist, daß sich die Plattformen ohne besondere Werkzeuge einbauen und auch wieder ausheben lassen.According to the invention, this object is achieved in a work platform of the generic type in that each lift-off device consists of elements or plates which can be displaced in the vertical direction, of which the outer plate facing the cross-beam provides at its lower end region with a positively engaging nose and at least that inner plate is wedge-shaped, and that both plates are guided on the guides provided on the end face of the platform in such a way that the outer plate in its lower and / or pivoted-out position engages behind the crossbar with its nose and the inner, directly or indirectly on the end face supported plate in its lower position clamps the outer plate in its locking position. In the working platform according to the invention, the hooks supporting the platforms on the crossbeams or crossbeams are locked to the crossbeams in that a pivoting and / or displaceable locking plate on the guide engages behind the crossbeam in the locking position with a nose, the locking position by one in a vertical position Is secured towards movable wedge, which moves automatically into its locking position due to the action of gravity. If the work platform or the scaffolding is subject to vibrations or movements, the locking of the hook connections only becomes firmer because the locking wedge immediately slides more firmly into its locking position if there should be a play loosening the locking. The lock according to the invention can be released in a simple manner by lifting the locking wedge, so that the individual platforms can be lifted again at any time as required, without further parts of the working platform or the scaffolding having to be dismantled. Since the Locking wedges automatically slip into their locking position after hooking the platforms onto the crossbars, a self-locking retention of the platforms is guaranteed. It is particularly advantageous that the platforms can be installed and removed again without special tools.
Zweckmäßigerweise sind beide Platten auf einem gemeinsamen Bolzen in Langlöchern geführt. Dabei braucht die äußere, mit der Verriegelungsnase versehene Platte nur mit einer Bohrung von solchem Durchmesser oder solcher Länge versehen sein, daß sie zumindest zwischen ihrer Verriegelungsstellung und ihrer Freigabestellung schwenken kann. Denn die äußere Verriegelungsplatte kann nur durch Verschwenken oder durch Verschwenken unter gleichzeitiger Ausführung einer Bewegung in ihrer Längsrichtung in ihre verriegelte und ihre entriegelte Stellung gelangen.Advantageously, both plates are guided on a common bolt in elongated holes. The outer plate provided with the locking lug need only be provided with a bore of such a diameter or length that it can pivot at least between its locking position and its release position. This is because the outer locking plate can only get into its locked and unlocked position by pivoting or by pivoting while simultaneously executing a movement in its longitudinal direction.
Hingegen ist die innere, mit einem sich nach unten hin verjüngenden Keilwinkel versehene Platte mit einem vertikalen Langloch von einer solchen Länge versehen, daß sie sich in eine die innere Platte freigebende Stellung anheben läßt und in ihrer verriegelten Stellung mit dem oberen Ende des Langloches höchstens gerade auf dem Führungsbolzen aufliegt.On the other hand, the inner plate, which is provided with a wedge angle tapering downwards, is provided with a vertical elongated hole of such a length that it can be raised to a position releasing the inner plate and, in its locked position, at most straight with the upper end of the elongated hole rests on the guide pin.
Die äußere, die Verriegelungsnase tragende Platte kann ebenfalls keilförmig ausgebildet sein. Zumindest weist sie auf ihrer Innenseite eine zu der inneren Keilplatte komplementäre Keilfläche auf.The outer plate carrying the locking lug can also be wedge-shaped. At least it has on its inside a wedge surface complementary to the inner wedge plate.
Zweckmäßigerweise sind die Platten relativ zueinander mit Verdrehsicherungen versehen. Die Verdrehsicherung kann aus zwei auf einer Platte befestigten Stiften bestehen, die zu dem Langloch der inneren Platte parallele Langlöcher der anderen Platte zumindest teilweise durchsetzen.The plates are expediently provided with anti-rotation devices relative to one another. The anti-rotation device can consist of two pins fastened on one plate, which at least partially penetrate elongated holes of the other plate parallel to the elongated hole of the inner plate.
Statt einer besonderen Verdrehsicherung können zur Führung der Platten auch zwei an der Stirnseite jeder Plattform befestigte Führungsbolzen vorgesehen sein.Instead of a special anti-rotation device, two guide bolts fastened to the end face of each platform can also be provided for guiding the plates.
Zweckmäßigerweise ist die innere Keilplatte an ihrem unteren Rand mit einer Verbreiterung oder Abwinkelung versehen, auf die zum Lösen der Verbindung ein Schlag ausgeübt werden kann.The inner wedge plate is expediently provided at its lower edge with a widening or angled portion, on which a blow can be applied to release the connection.
Zweckmäßigerweise sind der oder die Führungsbolzen an einem stirnseitigen Randprofil jeder Plattform befestigt, das eine ebene äußere Abstützfläche für die innere Keilplatte besitzt.The guide pin or pins are expediently fastened to an end edge profile of each platform, which has a flat outer support surface for the inner wedge plate.
Das Randprofil kann endseitig mit den Haken und in seinem mittleren Bereich mit den die Abhebsicherung bildenden Platten versehen sein.The edge profile can be provided at the end with the hooks and in its central area with the plates forming the anti-lift device.

Im mittleren oberen Bereich ist das Profil 2 mit einem quer verlaufenden Schraubbolzen 7 versehen, der das Profil 2 in fluchtenden Bohrungen durchsetzt. Auf dem mit einem Kopf 8 und einer Mutter 9 versehenen Schraubbolzen sind die Verriegelungsplatte 10 und die Keilplatte 11 in mittleren Langlöchern geführt. Die Verriegelungsplatte 10 weist an ihrem unteren äußeren Ende eine abgerundete, vorspringende Nase 12 auf, mit der diese in den aus den Figuren 3 und 4 ersichtlichen Verriegelungsstellungen den Querriegel 6 formschlüssig hintergreift.The
Die Verriegelungsplatte 12 ist in ihrem oberen mittleren Bereich mit einem Langloch relativ kurzer Länge versehen. In der Verriegelungsstellung stützt sich das obere Ende des Langloches der Verriegelungsplatte 10 auf dem Schraubbolzen 7 ab, oder die Verriegelungsplatte ist in ihrem oberen Endbereich mit einem stufenartigen Absatz 13 versehen, der sich auf der Mutter 8 abstützt.The
Die Keilplatte 11 ist in ihrem mittleren Bereich mit einem Langloch 15 von so großer Länge versehen, daß sich die Keilplatte so weit anheben läßt, daß sich die Verriegelungsplatte aus ihrer Verriegelungsstellung schwenken läßt.
