Abstract

A safety arrangement used while fitting lift doors has the form of a fittable railing which is screwed on at the bottom via two articulated parallelograms (2) in the sill recess of the shaft door opening. By means of the articulated parallelograms (2), the guard railing (1) can be brought into two different horizontal positions (A and B) and thus displaced by the amount X without removing it from the shaft door opening. This makes it possible to fit the guard railing (1) while the barricading of the shaft door opening provided by the owner is still in place and is not to be removed until the shaft door opening is closed off by the in the meantime fitted and closing shaft door. Therefore, this safety arrangement ensures a permanent guard against persons falling into the shaft during fitting of the shaft door. The guard railing (1) has a device for adaptation to different widths of opening and a constant distance of the articulated parallelograms from each other. <IMAGE>

Description

Die Erfindung betrifft eine Schutzeinrichtung für die Türmontage bei Aufzügen in Form eines montierbaren Geländers, welches während der Montagezeit der Tür den noch offenen Zugang zum Schacht gegen das Hineinfallen von Personen absichert.The invention relates to a protective device for door assembly in elevators in the form of a mountable railing, which secures the still open access to the shaft against falling into place during the assembly time of the door.

Bei der Erstellung einer Aufzugsinstallation ist insbesondere der Einbau und das Einrichten der Schachttüren mit einem erheblichen Unfallrisiko verbunden. Die nach dem Rohbau eines Gebäudes bauseitig angebrachten Abschrankungen bei den Schachtöffnungen auf den Stockwerken müssen für den Einbau der Schachttüren und Fronten entfernt werden. Das Montagepersonal arbeitet deshalb eine gewisse Zeit lang an der offenen Schachtöffnung und muss sich mittels (vorgeschriebenen) Sicherheitsmittel (Sicherheitsgurt und Seil) gegen Unfälle schützen. Die Gefahr des möglichen Hineinfallens in den Schacht ist damit aber noch nicht behoben, denn das Hineinfallen in den Schacht im angeseilten Zustand kann immer noch schwerere Verletzungen verursachen.When creating an elevator installation, installing and setting up the shaft doors in particular involves a considerable risk of accidents. The barriers attached to the shaft openings on the floors after the building shell has to be removed for the installation of the shaft doors and fronts. The assembly personnel therefore work on the open shaft opening for a certain time and must protect themselves against accidents using (prescribed) safety equipment (safety belt and rope). However, the risk of falling into the shaft has not yet been remedied, because falling into the shaft while in a rope can still cause serious injuries.

Es ist in der US-PS 3 425 165 ein in die Schachttüröffnung einklemmbares Geländer beschrieben, welches dank der einfachen Klemmvorrichtung rasch montiert und demontiert werden kann. Im montierten Zustand ist der Schutz gegen Hineinfallen gewährleistet, weil die, die Schachtöffnung seitlich überragenden Teile unten und oben ein Hineinstossen des Geländers auch bei erheblicher Krafteinwirkung verhindern. Ein unten angebrachtes Sockelblech verhindert zusätzlich das unbeabsichtigte Hineinschieben von Kleinobjekten bei Reinigungsarbeiten auf dem Stockwerkboden. Mittels der Klemmvorrichtung in Form des oberen, teleskopartig gegen Federkraft ineinander schiebbaren Querrohres kann das Geländer in einem bestimmten Bereich für verschiedene Türöffnungsbreiten verwendet werden.It is described in US Pat. No. 3,425,165 a railing which can be clamped into the shaft door opening and which can be assembled and disassembled quickly thanks to the simple clamping device. Protection is ensured in the assembled state against falling into, because the parts projecting laterally above the shaft opening at the top and bottom prevent the railing from being pushed in even with considerable force. A base plate attached below also prevents small objects from being inadvertently pushed in during cleaning work on the floor. By means of the clamping device in the form of the upper cross tube, which can be telescopically pushed against one another by spring force, the railing can be used in a certain area for different door opening widths.

Die etwas widersprüchliche Forderung, dass die Türöffnung während dem Arbeitsprozess der Türinstallation keinen Augenblick unverbarrikadiert sein soll, kann mit der beschriebenen Lösung nicht erfüllt werden, weil für Befestigungsarbeiten an der, der Schachtöffnung angrenzenden Schachtinnenwand das Schutzgeländer zwecks besserer Zugänglichkeit zeitweise entfernt werden muss. Damit sind die Unfallgefahren für das Aufzugspersonal immer noch erheblich.The somewhat contradictory requirement that the door opening should not be barricaded for a moment during the working process of the door installation cannot be met with the solution described, because the protective railing is better for fastening work on the inside wall of the shaft adjacent to the shaft opening Accessibility must be removed temporarily. This means that the risk of accidents for elevator personnel is still considerable.

Ferner kann das einklemmbare Geländer erst eingesetzt werden, wenn vorher die bauseitig angebrachte Absperrung entfernt wurde.Furthermore, the clampable railing can only be used if the on-site barrier has been removed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schutzeinrichtung für die Türmontage bei Aufzügen zu schaffen, welche während dem ganzen Montageprozess der Schachttürinstallation voll wirksam bleibt.The present invention has for its object to provide a protective device for door assembly in elevators, which remains fully effective during the entire assembly process of the shaft door installation.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die verwendete Sicherheitseinrichtung während allen Vorbereitungs- und Montagearbeiten im montierten und wirksamen Zustand belassen werden kann. Durch Verschieben des Schutzgeländers in Richtung des Schachtes können mit dieser Einrichtung unter ständiger Beibehaltung der Schutzfunktion der Einrichtung notfalls auch die Arbeiten an der, der Schachtöffnung angrenzenden Schachtinnenwand gefahrlos ausgeführt werden.The advantages achieved by the invention are essentially to be seen in the fact that the safety device used can be left in the assembled and effective state during all preparation and assembly work. By moving the guardrail in the direction of the shaft, this device can also be used to safely carry out work on the inner wall of the shaft adjacent to the shaft opening, while maintaining the protective function of the device.

Ein weiterer Vorteil liegt darin, dass auch während dem Verschieben selbst des Schutzgeländers in Schacht- oder umgekehrter Richtung ein unterbrechungsloser Schutz gewährt wird.Another advantage is that uninterrupted protection is provided even when the guardrail is moved in the shaft or the reverse direction.

1 shows a shaft door opening 3 in a front wall 3.6 and a floor 3.1. The lower half of the The shaft door opening is covered with a protective railing 1 to prevent it from entering the shaft 4. The protective railing 1 is fastened to the floor in a threshold recess 3.2 shown in dashed lines by means of a left handrail foot part 1.2 and a right handrail foot part 1.3 and a left and right bearing support which is not visible in this figure.

Ein in der Fig. 2 gezeigtes Gelenk-Parallelogramm 2 besteht aus dem linken Geländerfussteil 1.2 und schwenkbaren, parallel angeordneten Laschen 2.5, welche mit einem linken Lagersupport 2.1 beweglich verbunden sind. Der Lagersupport 2.1 ist auf einer horizontalen, seitlich zwecks ihrer Versteifung kurzschenklig abgekanteten Grundplatte 2.3 angeschweisst, welche auf der rechten Seite eine vertikale Bohrung 2.8 für eine hier nicht gezeigte Befestigungsschraube aufweist.An articulated parallelogram 2 shown in FIG. 2 consists of the left handrail foot part 1.2 and pivotable, parallel tabs 2.5, which are movably connected to a left bearing support 2.1. The bearing support 2.1 is welded onto a horizontal base plate 2.3, which is bent on one side for the purpose of stiffening and has a vertical bore 2.8 on the right side for a fastening screw, not shown here.

Die Laschen sind in einem beweglichen Support 2.2 in einem unteren Lager 1.21 und in einem oberen Lager 1.22 und im festen Support 2.1 in einem unteren Lager 2.11 und in einem oberen Lager 2.12 drehbar gehalten. In der voll ausgezogen gezeichneten Position A ist das Schutzgeländer 1 in Richtung Schacht 4 geschwenkt und wird in dieser Position von einer Anschlagplatte 2.6 gehalten, welche an der linken oberen Schmalseite der oberen Lasche 2.5 anliegt. Die gestrichelt gezeichnete Position B zeigt die Anordnung in einer um 180° nach rechts, in Richtung Stockwerkboden 3.1 geschwenkten Position. In der Position B wird die Anordnung wieder mittels der Anschlagplatte 2.6 und der oberen Lasche 2.5 gehalten. Die Schwenkbewegung erfolgt entlang der gestrichelt gezeichneten Kreisbögen und bewirkt eine Horizontalverschiebung des Schutzgeländers 1 um den Betrag X. Der Betrag X entspricht der doppelten Länge der Achsdistanz einer Lasche 2.5. Die untere Lasche 2.5 ist vorderseitig und die obere Lasche 2.5 ist hinterseitig am festen Support 2.1 und am beweglichen Support 2.2 angebracht, wodurch erst die kollisionsfreie 180°-Bewegung des Gelenk-Parallelogrammes ermöglicht wird.The tabs are rotatably held in a movable support 2.2 in a lower bearing 1.21 and in an upper bearing 1.22 and in the fixed support 2.1 in a lower bearing 2.11 and in an upper bearing 2.12. In the fully drawn position A, the guardrail 1 is pivoted in the direction of the shaft 4 and is held in this position by a stop plate 2.6, which rests on the upper left narrow side of the upper tab 2.5. The position B shown in broken lines shows the arrangement in a position pivoted through 180 ° to the right in the direction of the floor 3.1. In position B the arrangement is held again by means of the stop plate 2.6 and the upper tab 2.5. The pivoting movement takes place along the dashed circular arcs and causes a horizontal displacement of the guardrail 1 by the amount X. The amount X corresponds to twice the length of the axis distance of a bracket 2.5. The lower bracket 2.5 is on the front and the upper bracket 2.5 is attached on the rear to the fixed support 2.1 and to the movable support 2.2, which only enables the collision-free 180 ° movement of the joint parallelogram.

Die Fig. 3 zeigt eine Frontansicht des Schutzgeländers 1, welches beispielsweise als Schweisskonstruktion mit entsprechenden vertikal und horizontal angeordneten Rohren 1.1 gebaut ist. Je am unteren Ende des rechten und mittleren vertikalen Rohres 1.1 ist via Anschlagplatte 2.6 bzw. 2.7 das Geländerfussteil 1.2 bzw. 1.3 angeschweisst. Mit den Fig. 4 bis 8 wird die Funktion der Einrichtung in fünf Folgeschritten illustriert. In der Fig. 4 ist die Schachttüröffnung 3 mit einem unteren Querbalken 3.4 und einem oberen Querbalken 3.5 bauseitig provisorisch verbarrikadiert. In der Schwellenaussparung 3.2 ist ein Türsupport 3.3 in Form eines schachtseitig kurzschenklig nach oben abgekanteten Profilbleches montiert, was ohne Entfernen der Querbalken 3.4 und 3.5 erfolgen konnte. Ein Hilfslot 4.1 bezeichnet die Mitte des einzubauenden Türelementes. Es wird eine Distanz Y zwischen Lotlinie und vertikalem Schenkel des Türsupportes 3.3 eingestellt. Der Türsupport 3.3 ist an vorgängig im Boden verankerten Schraubbolzen 3.7 angeschraubt.Fig. 3 shows a front view of the guardrail 1, which, for example, as a welded construction corresponding vertically and horizontally arranged pipes 1.1 is built. At the lower end of the right and middle vertical pipe 1.1, the railing foot part 1.2 or 1.3 is welded on via stop plate 2.6 or 2.7. 4 to 8 illustrate the function of the device in five subsequent steps. 4, the shaft door opening 3 is provisionally barricaded on site by a lower cross bar 3.4 and an upper cross bar 3.5. In the threshold cut-out 3.2, a door support 3.3 is mounted in the form of a profile plate that is bent upwards on the shaft side, which could be done without removing the crossbeams 3.4 and 3.5. An auxiliary solder 4.1 denotes the center of the door element to be installed. A distance Y between the vertical line and the vertical leg of the door support 3.3 is set. The door support 3.3 is screwed onto screw bolts 3.7 previously anchored in the floor.

In der Fig. 5 ist das montierte Schutzgeländer 1 gezeigt, welches via Bodenplatten 2.3/2.4 und den Bohrungen 2.8 direkt an den Schraubbolzen 3.7 am Boden der Schwellenaussparung 3.2, oder an separaten, nicht dargestellten Schraubbolzen auf dem Türsupport 3.3 fest angeschraubt wird. Nach dieser Befestigungsoperation können die Querbalken 3.4/3.5, welche bis jetzt die Schachttüröffnung verbarrikadiert haben, entfernt werden. Das Gelenkparallelogramm 2 ist auf die rechte Seite in Richtung Stockwerk geschwenkt und kollidiert so nicht mit den noch eingesetzten Querbalken 3.4/3.5.In Fig. 5 the assembled guardrail 1 is shown, which is firmly screwed via base plates 2.3 / 2.4 and the holes 2.8 directly to the bolts 3.7 on the bottom of the threshold recess 3.2, or to separate bolts, not shown, on the door support 3.3. After this fastening operation, the cross beams 3.4 / 3.5, which have so far barricaded the shaft door opening, can be removed. The articulated parallelogram 2 is pivoted on the right side towards the floor and does not collide with the crossbars 3.4 / 3.5 still in use.

Beim nächsten Schritt nach Fig. 6 ist das Gelenkparallelogramm 2 auf die linke Seite in Richtung Schacht 4 geschwenkt und das Schutzgeländer 1 gibt die seitliche Innenseite der Schachttüröffnung 3 für die Montage eines Türbefestigungsprofiles 5 frei. Durch leichtes Hineinlehnen in den Schacht 4 können, falls erforderlich, bei dieser Position des Schutzgeländers 1 weitere Vorbereitungsarbeiten und/oder Montagearbeiten an der, der Schachttüröffnung 3 direkt angrenzenden Schachtinnenwand gefahrlos ausgeführt werden.In the next step according to FIG. 6, the articulated parallelogram 2 is pivoted on the left side in the direction of the shaft 4 and the guardrail 1 releases the inner side of the shaft door opening 3 for the installation of a door fastening profile 5. By slightly leaning into the shaft 4, if necessary, further preparatory work and / or assembly work on the inner wall of the shaft directly adjacent to the shaft door opening 3 can be carried out safely in this position of the guardrail 1.

Gemäss Fig. 7 wird nun eine Schachttürbaugruppe 6 mit einem Hebezeug 7 zur aktuellen Schachttüröffnung 3 gebracht. Durch Umschwenken auf die Stockwerkseite des Gelenkparallelogrammes 2 kann, gemäss Fig. 8 die Schachttürbaugruppe 6 an den vorbereiteten Platz gesetzt und dort befestigt werden. So bald die Schachttür geschlossen ist, kann das Schutzgeländer 1 entfernt werden, nach dem während der ganzen Schachttürmontage ohne Unterbrechung ein Schutz gegen Hineinfallen von Personen in den Liftschacht vorhanden war.7, a shaft door assembly 6 is now brought to the current shaft door opening 3 with a hoist 7. By pivoting to the floor side of the articulated parallelogram 2, the shaft door assembly 6 can be attached to the, according to FIG prepared place and be fixed there. As soon as the shaft door is closed, the guardrail 1 can be removed, after which there was protection against falling into the elevator shaft without interruption during the entire installation of the shaft door.

Durch das Gelenkparallelogramm 2 ist es möglich, das Schutzgeländer 1 ohne dessen Entfernung auf zwei verschiedene, der jeweils erforderten Zugänglichkeit für die entsprechenden Arbeiten dienende, Positionen zu setzen.The articulated parallelogram 2 makes it possible to set the protective railing 1 without removing it from two different positions that serve the required accessibility for the corresponding work.

In einer weitergebildeten Form weist das Schutzgeländer 1 gemäss Fig. 9 eine Verstelleinrichtung 11 auf, mit welcher das Schutzgeländer 1 auf verschiedene Oeffnungsbreiten angepasst werden kann. Ein linker Teil 8 weist in seinen Horizontalrohren 8.1 in regelmässigen Abständen Querlöcher 8.2 auf und kann in Horizontalrohre 9 des rechten Teils hineingeschoben und bei der gewünschten Breite mittels nicht dargestellten gegen Herausfallen gesicherten Sicherheitsbolzen bei den Querbohrungen 10 arretiert werden.In a further developed form, the guardrail 1 according to FIG. 9 has an adjusting device 11 with which the guardrail 1 can be adapted to different opening widths. A left part 8 has transverse holes 8.2 in its horizontal tubes 8.1 at regular intervals and can be pushed into horizontal tubes 9 of the right part and can be locked at the desired width by means of safety bolts (not shown) secured against falling out in the transverse bores 10.

Eine Anordnung in schematischer Darstellung gemäss Fig. 10 weist ein Zusatzgelenk 11 auf, bestehend aus einem am Schutzgeländer 1 waagerecht nach rechts vorstehenden Ausleger 10, welcher an seinem rechten Ende ein Lager 10.1 aufweist, einer Gelenklasche 9 und einem vertikalen Zusatzsupport 8, welcher an seinem oberen Ende ein Lager 8.1 aufweist. Wenn sich bei der Schwenkbewegung des Schutzgeländers 1 die Parallelogramm-Gelenklaschen 2.5 momentan in vertikaler Stellung befinden (Position C), wird mit dieser Anordnung eine zusätzliche Stabilisierung erreicht.An arrangement in a schematic representation according to FIG. 10 has an additional joint 11, consisting of a bracket 10 protruding horizontally to the right on the protective railing 1, which has a bearing 10.1 at its right end, a hinge plate 9 and a vertical additional support 8, which is attached to it has a bearing 8.1 upper end. If, during the pivoting movement of the guardrail 1, the parallelogram link plates 2.5 are currently in the vertical position (position C), additional stabilization is achieved with this arrangement.

Die beiden Geländerfussteile 1.2, 1.3 weisen für alle Geländerausführungen den gleichen Abstand Z zueinander auf. Das hat zum Zweck, dass auch die Löcher für die Schraubbolzen 3.7 in der Schwellenaussparung 3.2 für alle Oeffnungsbreiten mit dem gleichen Abstand Z und dementsprechend auch mit ein und derselben Bohrlehre gebohrt werden können.The two railing base parts 1.2, 1.3 have the same distance Z from one another for all railing versions. The purpose of this is that the holes for the screw bolts 3.7 can also be drilled in the threshold recess 3.2 for all opening widths with the same distance Z and accordingly with one and the same drilling jig.
