Description

Die Erfindung betrifft ein computerunterstütztes Verfahren zur Konstruktion und Fertigung eines Treppenschrägaufzuges, insbesondere des Tragwerks eines Treppenschrägaufzuges. Die Erfindung betrifft ferner ein entsprechendes Computer-Konstruktionsprogramm, ein entsprechendes Computerprogramm-Speichermedium und einen entsprechenden Computer mit diesem Speichermedium. Die Erfindung betrifft auch ein mittels des erfindungsgemäßen Verfahrens konstruiertes und gefertigtes Treppenschrägaufzug-Tragwerk.The invention relates to a computer-aided method for the construction and manufacture of a staircase inclined elevator, in particular of the structure of a staircase inclined elevator. The invention further relates to a corresponding computer design program, a corresponding computer program storage medium and a corresponding computer with this storage medium. The invention also relates to a staircase lift structure constructed and manufactured by means of the method according to the invention.

Aus dem Stand der Technik, beispielsweise der EP 1 700 812 B1 , der WO 2016/028146 A1 oder der WO 2013/137733 A1 sind Treppenschrägaufzüge bekannt, unter anderen solche, deren einen Personensitz umfassende Transporteinheit an zwei übereinanderliegenden und als Rohre ausgestalteten Laufschienen entlanggeführt wird. Der räumliche Verlauf dieser Führungsrohre relativ zueinander über die Fahrtstrecke hinweg wird somit zunächst einmal durch die Transporteinheit bzw. deren vordefinierte geometrische Ausgestaltung vorgegeben. Darüber hinaus muss der räumliche Verlauf des Tragwerks auch an die geometrischen Vorgaben des späteren Einsatzortes angepasst werden. Um eine zufriedenstellende Funktion zu gewährleisten, werden die Tragwerke solcher Treppenschrägaufzüge manuell auf einem Montagestand gefertigt. Zur Anpassung der beiden Rohre an die geometrischen Vorgaben des späteren Einsatzortes und zusätzlich an die geometrische Ausgestaltung der Transporteinheit muss der räumliche Verlauf beider Rohre in zahlreichen, teilweise iterativen Schritten manuell aufeinander abgestimmt werden. Beide Rohre werden hierfür aus mehreren Teilstücken zusammengesetzt, deren Ausrichtung zueinander oft mehrmals verändert werden muss. Dies erfordert nicht nur viel technisches Knowhow und Erfahrung, sondern bringt zwangsläufig auch einen sehr hohen manuellen Fertigungsaufwand mit sich.From the prior art, for example the EP 1 700 812 B1 , of the WO 2016/028146 A1 or the WO 2013/137733 A1 staircase inclined elevators are known, among others those whose one person seat comprehensive transport unit is guided along two superimposed and designed as tubes rails. The spatial course of these guide tubes relative to one another over the journey path is thus initially predetermined by the transport unit or its predefined geometric design. In addition, the spatial course of the structure must also be adapted to the geometric specifications of the later site. To ensure a satisfactory function, the structures of such inclined stair lifts are manufactured manually on an assembly stand. To adapt the two tubes to the geometric specifications of the later site and in addition to the geometric design of the transport unit, the spatial course of both tubes must be manually matched to one another in numerous, partly iterative steps. For this purpose, both tubes are composed of several sections whose alignment with each other often has to be changed several times. This not only requires a lot of technical know-how and experience, but inevitably brings with it a very high manual production effort.

Es ist die Aufgabe der vorliegenden Erfindung, diesen Fertigungsaufwand zu reduzieren. Diese Aufgabe wird durch den Gegenstand der nebengeordneten Ansprüche 1, 7 und 8 gelöst. Die Unteransprüche definieren dabei bevorzugte Ausführungsformen der vorliegenden Erfindung.It is the object of the present invention to reduce this manufacturing effort. This object is achieved by the subject matter of the independent claims 1, 7 and 8. The dependent claims define preferred embodiments of the present invention.

Das erfindungsgemäße computerimplementierte Verfahren zur Konstruktion des Tragwerks eines Treppenschrägaufzuges mit einer ersten Laufschiene, einer zweiten Laufschiene und einer an diesen geführten Transporteinheit umfasst demnach folgende Schritte:

  • Festlegen eines räumlichen Verlaufs der ersten Laufschiene entsprechend den von der Tragwerksinstallation vorgegebenen Rahmenbedingungen;
  • Festlegen einer Raumachse entsprechend den von der Tragwerksinstallation vorgegebenen Rahmenbedingungen;
  • Festlegen einer geometrischen Ausgestaltung der Transporteinheit;
  • Bestimmen eines räumlichen Verlaufs der zweiten Laufschiene, der zur Führung der zur Raumachse ausgerichteten Transporteinheit an der ersten und der zweiten Laufschiene notwendig ist.
The computer-implemented method according to the invention for constructing the structure of a staircase inclined elevator with a first running rail, a second running rail and a transport unit guided thereon accordingly comprises the following steps:
  • Defining a spatial course of the first track according to the framework conditions prescribed by the structural installation;
  • Defining a spatial axis according to the framework conditions prescribed by the structural installation;
  • Determining a geometric configuration of the transport unit;
  • Determining a spatial course of the second track, which is necessary for guiding the aligned to the space axis transport unit on the first and the second track rail.

Mit anderen Worten wird zunächst der räumliche Verlauf der ersten Tragwerks-Laufschiene festgelegt, und zwar entsprechend den geometrischen Vorgaben des späteren Einbau- bzw. Einsatzortes des Treppenlifts. In diesem Zusammenhang ist es vorstellbar, dass der räumliche Verlauf der ersten Schiene mit Hilfe eines Konstruktionsprogramms an ein virtuelles Modell des späteren Einsatzortes angepasst wird. Es ist jedoch ebenso vorstellbar, dass der räumliche Verlauf der ersten Laufschiene bereits durch deren Fertigung festgelegt wurde, woraufhin dieser für das weitere Konstruktionsverfahren nur noch digitalisiert werden muss. So kann die bereits gefertigte Laufschiene vermessen werden und die gewonnenen Daten für das weitere computerimplementierte Konstruktionsverfahren dem entsprechenden Computer zur Weiterverarbeitung zugeführt werden.In other words, initially the spatial course of the first structural runner rail is determined, in accordance with the geometric specifications of the later installation or deployment location of the stairlift. In this context, it is conceivable that the spatial progression of the first rail is adapted by means of a design program to a virtual model of the later work site. However, it is also conceivable that the spatial course of the first track was already determined by their production, whereupon this only has to be digitized for the further construction process. Thus, the already manufactured track rail can be measured and the data obtained for the further computer-implemented design process are supplied to the appropriate computer for further processing.

Ferner wird beim erfindungsgemäßen Verfahren eine Raumachse, also eine Achse im dreidimensionalen Raum relativ zum Verlauf der ersten Schiene festgelegt. An dieser Achse wird die Transporteinheit des Treppenlifts letztendlich ausgerichtet. Anders ausgedrückt legt die Raumachse also die Ausrichtung der Transporteinheit relativ zur ersten Laufschiene fest.Furthermore, in the method according to the invention, a spatial axis, that is to say an axis in three-dimensional space, is determined relative to the course of the first rail. At This axis is the transport unit of the stairlift finally aligned. In other words, the spatial axis defines the orientation of the transport unit relative to the first track.

Zuletzt muss noch die geometrische Ausgestaltung der Transporteinheit bekannt sein, die ja letztendlich die für die Führung der Transporteinheit an und entlang beider Laufschienen notwendige Relativposition beider Laufschienen vorgibt.Finally, the geometric design of the transport unit must be known, which ultimately dictates the relative position of both rails required for guiding the transport unit on and along both rails.

Die obigen Daten definieren somit die Rahmenbedingungen für den räumlichen Verlauf der zweiten Laufschiene des Tragwerks, innerhalb welcher die Transporteinheit am Einsatzort zufriedenstellend an und entlang beider Laufschienen geführt werden kann.The above data thus define the framework for the spatial course of the second track of the structure, within which the transport unit can be performed satisfactorily on and along both rails at the site.

Gemäß der vorliegenden Erfindung wird zur Bestimmung des räumlichen Verlaufs der zweiten Laufschiene der räumliche Positionsverlauf der am und entlang der ersten Laufschiene geführten und an der Raumachse ausgerichteten Transporteinheit simuliert, und zwar mittels einer dreidimensionalen Modellsimulation. Anders ausgedrückt kann ein virtuelles Modell der Transporteinheit an einem virtuellen Modell der ersten Laufschiene mit einem bereits festgelegten räumlichen Verlauf entlanggeführt werden, wobei die Transporteinheit darüber hinaus an der bereits ebenfalls festgelegten Raumachse ausgerichtet ist. Zur Ausrichtung der Transporteinheit an der Raumachse ist zu sagen, dass die Transporteinheit bevorzugterweise so an der Raumachse ausgerichtet ist, dass die Hochachse der Transporteinheit, die senkrecht auf die Sitzfläche der Transporteinheit stehen kann, parallel zur vordefinierten Raumachse verläuft. Mit der Simulation der an der Raumachse ausgerichteten und an der ersten Schiene entlanggeführten Transporteinheit wird durch die Transporteinheit selbst der räumliche Verlauf der zweiten Laufschiene festgelegt bzw. kurvenschreiberartig im dreidimensionalen virtuellem Raum regelrecht aufgezeichnet.According to the present invention, the spatial position profile of the transport unit guided on and along the first track rail and aligned on the spatial axis is simulated by means of a three-dimensional model simulation in order to determine the spatial course of the second track rail. In other words, a virtual model of the transport unit can be guided along a virtual model of the first track with an already defined spatial progression, the transport unit also being aligned with the spatial axis already defined. For alignment of the transport unit to the spatial axis is to say that the transport unit is preferably aligned with the space axis, that the vertical axis of the transport unit, which may be perpendicular to the seat surface of the transport unit, parallel to the predefined spatial axis. With the simulation of the transport unit oriented on the spatial axis and guided along the first rail, the spatial progression of the second running rail is determined by the transport unit itself or recorded in a curve-recorder-like manner in three-dimensional virtual space.

Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung umfasst die Simulation des räumlichen Positionsverlaufs der Transporteinheit die Simulation der räumlichen Position zumindest einer, insbesondere aller an zumindest der ersten oder zweiten Laufschiene angreifenden Rollen der Transporteinheit. So können mittels Simulation auch die Punkte berücksichtigt werden, an denen die einzelnen Laufrollen der Transporteinheit an den Laufschienen anliegen. Da die Laufrollen durch deren Koppelung an der Transporteinheit in ihrer räumlichen Lage mehr oder weniger stark aneinander gebunden sind, bilden die Kontaktpunkte der einzelnen Rollen weitere Rahmenbedingungen für den Verlauf der zweiten Laufschiene.According to a further embodiment of the present invention, the simulation of the spatial position profile of the transport unit comprises the simulation of spatial position of at least one, in particular all acting on at least the first or second track rail rollers of the transport unit. By means of simulation, the points at which the individual rollers of the transport unit lie against the rails can thus also be taken into account. Since the rollers are more or less strongly bound together by their coupling to the transport unit in their spatial position, the contact points of the individual rollers form further framework conditions for the course of the second track.

Im Rahmen der vorliegenden Erfindung ist es möglich, zur Bestimmung des räumlichen Verlaufs der zweiten Laufschiene für die einzelnen Punkte des Schienenverlaufs sämtliche Raumkoordinaten in einem Arbeitsschritt zu berechnen. Es ist jedoch ebenso vorstellbar, dass die Raumkoordinaten der einzelnen Punkte des Schienenverlaufs getrennt voneinander berechnet werden, wobei es insbesondere vorstellbar ist, dass der horizontale Verlauf getrennt vom vertikalen Verlauf der zweiten Laufschiene berechnet wird.In the context of the present invention, it is possible to calculate all spatial coordinates in one work step for determining the spatial course of the second track for the individual points of the track. However, it is also conceivable that the spatial coordinates of the individual points of the rail track are calculated separately, it being particularly conceivable that the horizontal course is calculated separately from the vertical course of the second track.

Ferner ist es möglich, zur Bestimmung des räumlichen Verlaufs der zweiten Laufschiene den Verlauf der Mittelachse der zweiten Laufschiene zu bestimmen, insbesondere wiederum deren horizontalen Verlauf und deren vertikalen Verlauf getrennt voneinander zu bestimmen.Further, it is possible to determine the course of the central axis of the second track for determining the spatial course of the second track, in particular again to determine their horizontal course and their vertical course separately.

Die Richtung der Raumachse, an welcher die Transporteinheit ausgerichtet werden soll, kann sich grundsätzlich über den Verlauf der ersten bzw. der zweiten Laufschiene verändern. Beispielsweise kann man sich vorstellen, dass die Transporteinheit entlang des gesamten Streckenverlaufs eine gewisse Neigung aufweist, etwa quer zur Fahrtrichtung nach vorne oder nach hinten geneigt. Es kann aber auch vorgesehen sein, dass die Raumachse und somit die Neigung der Transporteinheit sich in bestimmten Streckenabschnitten, etwa in Kurven von deren sonstiger Ausrichtung im übrigen Streckenverlauf unterscheidet. Vorzugsweise ist die Richtung der Raumachse allerdings über die gesamte Fahrtstrecke, also den gesamten Verlauf der Laufschienen konstant, so dass die Transporteinheit beim späteren Einsatz über den gesamten Streckenverlauf an einer einzigen Richtung ausgerichtet ist. So kann die Raumachse parallel zur Richtung der Schwerkraft in der letztendlichen Einbaulage des Treppenlifts ausgerichtet sein. Auf diese Weise wird die Transporteinheit im späteren Einsatz stets in gleicher Weise relativ zum Schwerkraftvektor ausgerichtet sein.The direction of the spatial axis, at which the transport unit is to be aligned, can fundamentally change over the course of the first or the second running rail. For example, one can imagine that the transport unit along the entire route has a certain inclination, inclined approximately transversely to the direction of travel forward or backward. But it can also be provided that the spatial axis and thus the inclination of the transport unit differs in certain sections, such as curves of their other orientation in the rest of the route. Preferably, however, the direction of the spatial axis is constant over the entire route, ie the entire course of the rails, so that the transport unit during subsequent use over the entire route on a single direction is aligned. Thus, the space axis can be aligned parallel to the direction of gravity in the final installation position of the stair lift. In this way, the transport unit will always be oriented in the same manner relative to the gravity vector in later use.

Vorzugsweise ist es die obere, beispielsweise rohrförmige Laufschiene des Tragwerks, deren räumlicher Verlauf zunächst festgelegt wird, auf dessen Basis dann der räumliche Verlauf der unteren Tragwerks-Laufschiene bestimmt wird. Die Begriffe "oben" und "unten" beziehen sich dabei auf die Einbauposition am Einsatzort.Preferably, it is the upper, for example, tubular running rail of the structure, the spatial course is first determined, on the basis of which the spatial course of the lower supporting rail is then determined. The terms "top" and "bottom" refer to the installation position at the place of use.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein Verfahren zur Fertigung des Tragwerks eines Treppenschrägaufzuges mit einer ersten Laufschiene, einer zweiten Laufschiene und einer an diesen geführten Transporteinheit, mit folgenden Schritten:

  • Fertigung, insbesondere Installation der ersten Laufschiene mit einem festgelegten räumlichen Verlauf;
  • Durchführung eines wie oben beschriebenen computerimplementierten Konstruktionsverfahrens;
  • Fertigung insbesondere Installation der zweiten Laufschiene mit dem mittels des Konstruktionsverfahrens bestimmten räumlichen Verlauf.
A further aspect of the present invention relates to a method for producing the structure of a staircase inclined elevator with a first track rail, a second track rail and a transport unit guided thereon, with the following steps:
  • Production, in particular installation of the first track with a fixed spatial course;
  • Performing a computer-implemented design method as described above;
  • Production in particular installation of the second track with the determined by the construction method spatial course.

Wie bereits weiter oben angedeutet, kann zunächst eine erste, vorzugsweise obere Laufschiene mit einem räumlichen Verlauf gefertigt werden, der am für den späteren Einsatzort des Treppenlifts erforderlich ist. Mittels des wie oben beschriebenen Konstruktions- bzw. Simulationsverfahrens kann nach Vermessung dieser Laufschiene der räumliche Verlauf der zweiten, vorzugsweise unteren Laufschiene des Tragwerks berechnet werden. Es ist jedoch ebenso vorstellbar, dass der räumliche Verlauf des Tragwerks rein virtuell bestimmt wird. So kann etwa der räumliche Verlauf der ersten Laufschiene unter Zuhilfenahme eines Modells des späteren Einsatzortes festgelegt werden, und sogleich auch mittels der oben beschriebenen Konstruktion bzw. Simulation der räumliche Verlauf der unteren Laufschiene bestimmt werden.As already indicated above, first, a first, preferably upper track with a spatial course can be made, which is required for the later site of use of the stairlift. By means of the construction or simulation method as described above, the spatial profile of the second, preferably lower running rail of the supporting structure can be calculated after measuring this running rail. However, it is also conceivable that the spatial course of the structure is determined purely virtual. Thus, for example, the spatial course of the first track can be determined with the aid of a model of the later site, and at once by means of the above described construction or simulation of the spatial course of the lower track.

Mithilfe der vorliegenden Erfindung ist der notwendige räumliche Verlauf zumindest der zweiten Laufschiene bereits vor deren Fertigung genau bekannt und muss somit während der Fertigung nicht mehr zeitaufwändig verändert und angepasst werden, etwa durch Abtrennen eines Schienenabschnitts und dessen Wiederanbringung mit einer veränderten Ausrichtung, Krümmung und/oder Länge.By means of the present invention, the necessary spatial course of at least the second track is already known precisely prior to its production and thus does not need to be changed and adjusted time-consuming during production, for example by separating a rail section and reattaching it with a changed orientation, curvature and / or Length.

Weitere Aspekte der vorliegenden Erfindung betreffen folglich ein Computerprogramm-Speichermedium bzw. einen Datenträger mit einem darauf gespeicherten Programm, das einen Computer zur Durchführung eines oben beschriebenen Konstruktionsverfahrens veranlasst. Ein zusätzlicher Aspekt der vorliegenden Erfindung betrifft einen Computer, der ein entsprechendes Speichermedium bzw. einen entsprechenden Datenträger aufweist und/oder auf welchem ein wie oben beschriebenes Computerprogramm geladen ist.Further aspects of the present invention consequently relate to a computer program storage medium or a data carrier with a program stored thereon, which causes a computer to carry out a construction method described above. An additional aspect of the present invention relates to a computer having a corresponding storage medium or a corresponding data carrier and / or on which a computer program as described above is loaded.

Die Erfindung wird nachfolgend anhand der Zeichnungen an Ausführungsbeispielen näher erläutert. Die hierin beschriebenen Merkmale können einzeln sowie in jedweder sinnvollen Kombination von der vorliegenden Erfindung umfasst werden. Es zeigen:

The invention will be explained in more detail with reference to the drawings of exemplary embodiments. The features described herein may be included individually as well as in any meaningful combination of the present invention. Show it:
FIG. 1
an inclined staircase lift with a structure comprising two rails,
FIG. 2

In der Figur 1 ist ein Treppenschrägaufzug/Treppenlift gezeigt, dessen Transporteinheit 3 an zwei übereinanderliegenden rohrförmigen Laufschienen 1 und 2 derart geführt wird, dass diese beim Verfahren entlang der Schienen 1 und 2 stets zum des Schwerkraftvektor G ausgerichtet ist. Der Sitz (in der Figur 2 nicht bezeichnet) der Transporteinheit 3 nimmt somit zu jeder Zeit eine "lotrechte" Lage ein und wird folglich nur um den Vektor G herum verdreht.In the FIG. 1 a staircase inclined elevator / stairlift is shown, the transport unit 3 is guided on two superimposed tubular rails 1 and 2 such that it is always aligned in the process along the rails 1 and 2 to the gravity vector G. The seat (in the FIG. 2 not designated) of the transport unit 3 thus assumes a "vertical" position at all times and consequently is rotated only around the vector G.

Die Figur 2 zeigt eine entsprechende Transporteinheit 3, auf deren Rückseite mehrere zumindest teilweise relativ zur Transporteinheit 3 positionsvariable Laufrollen 4 und 5 gelagert sind, mittels derer die Transporteinheit 3 sowohl an den Verlauf der oberen Laufschiene 1 als auch an den Verlauf der unteren Laufschiene 2 gekoppelt ist. Ferner ist in der Figur 2 die zentrale Faser bzw. Mittelachse 6 der zweiten, unteren Laufschiene 2 zu sehen, deren räumlicher Verlauf zur oberen Laufschiene 1 mittels des erfindungsgemäßen Konstruktionsverfahrens berechnet werden kann, so dass die Transporteinheit 3 entlang des Schienenverlaufs stets ihre lotrechte Ausrichtung beibehält.The FIG. 2 shows a corresponding transport unit 3, on the back of a plurality of at least partially relative to the transport unit 3 positionally variable rollers 4 and 5 are mounted, by means of which the transport unit 3 is coupled to both the course of the upper track rail 1 and the course of the lower track rail 2. Furthermore, in the FIG. 2 to see the central fiber or central axis 6 of the second, lower track 2, the spatial course can be calculated to the upper track 1 by means of the construction method according to the invention, so that the transport unit 3 always maintains its vertical orientation along the track.

Die Figur 3 zeigt ein Flussdiagramm mit den wesentlichen Schritten des erfindungsgemäßen Konstruktionsverfahrens. Auf Basis gewonnener Daten bezüglich des räumlichen Verlaufs der ersten Laufschiene, der Raumachse und der geometrischen Ausgestaltung der Transporteinheit kann letztendlich der notwendige räumliche Verlauf der zweiten Laufschiene berechnet werden. Diese Daten können dabei in einer beliebigen Reihenfolge oder aber auch gleichzeitig gewonnen werden, so dass die Abfolge der ersten drei wesentlichen Schritte des in der Figur 3 zu sehenden Verfahrens nicht zwingend als zeitliche Abfolge zu deuten ist.The FIG. 3 shows a flowchart with the essential steps of the construction method according to the invention. On the basis of data obtained with regard to the spatial course of the first running rail, the spatial axis and the geometric configuration of the transport unit, the necessary spatial course of the second running rail can ultimately be calculated. This data can be obtained in any order or at the same time, so that the sequence of the first three essential steps in the FIG. 3 not necessarily to be interpreted as a temporal sequence.
