Abstract

The invention relates to a guide rail for an inclined lift. The essence of the invention consists in the fact that the roughly U-shaped guide rail having a web and two legs has an additional supporting rail in the area between its two legs, which supporting rail forms a running surface for the bottom idler. This measure enables an additional inner guide rail (rail O) to be allocated to the inclined lift without the dimensions of the idler assemblies or of the further guide rails 1 - n having to be changed. <IMAGE>

Description

Die Erfindung betrifft eine Führungsschiene für den an einem Lastaufnahmemittel eines Schrägaufzuges gelagerten, aus Oberrollen und Unterrollen gebildeten Tragrollensatzes, wobei die Unterrollen zwischen den Schenkeln der im wesentlichen U-förmigen Führungsschiene verlaufend angeordnet sind.The invention relates to a guide rail for the support roller set, which is mounted on a load suspension device of an inclined elevator and is formed from upper rollers and lower rollers, the lower rollers being arranged running between the legs of the essentially U-shaped guide rail.

Es sind derartige Führungsschienen bekannt (DE-OS 35 41 836), die eine Mehrzahl aneinandergefährter Profile bilden und an denen der sogenannte Schlitten eines Lastaufnahmemittels mittels Ober- und Unterrollen geführt ist. Die Ober- und Unterrollen sind üblicherweise in Schwingen gelagert (DE-PS 32 22 508); dabei muß der Abstand zwischen der dem oberen Schenkel der U-förmigen Führungsschiene aufliegenden Oberrolle und der diesen Schenkel unterfassenden Unterrolle so gewählt sein, daß alle Führungsschienen eingefahren werden können, ohne daß es zu Zwängungen zwischen Oberrolle und Unterrolle kommt. Die Unterrolle hat bei den zum Std. d. T. gehörenden Tragrollensätzen ausschließlich eine Sicherungsfunktion gegen Abheben des Schlittens, d.h. gegen Kippen des Schlittens entgegen der Aufzugsrichtung. Die vom Lastaufnahmebehälter auf dei Führungsschienen zu übertragende Kraft wird hauptsächlich von den Oberrollen auf die Oberseiten der oberen Schenkel der U-förmigen Führungsschienen übertragen.Such guide rails are known (DE-OS 35 41 836) which form a plurality of profiles which are brought together and on which the so-called carriage of a load-carrying means is guided by means of upper and lower rollers. The upper and lower rollers are usually mounted in rockers (DE-PS 32 22 508); the distance between the upper roller resting on the upper leg of the U-shaped guide rail and the lower roller underneath this leg must be selected such that all Guide rails can be retracted without causing constraints between the top roller and bottom roller. The lower role has at d. T. belonging idler sets only a safety function against lifting the carriage, ie against tilting the carriage against the direction of the elevator. The force to be transmitted from the load receptacle on the guide rails is mainly transmitted from the upper rollers to the upper sides of the upper legs of the U-shaped guide rails.

In der Praxis besteht somit die Schiwerigkeit, den Abstand zwischen der Unterkante der Oberrolle und der Oberkante der Unterrolle so festzulegen, daß _ in Abhängigkeit von der Anzahl der ineinander zu fahrenden Führungsschienen _ zum einen keine Zwängungen zwischen Oberrolle und Unterrolle bei völlig eingefahrenem Schrägaufzug auftreten, zum anderen jedoch kein unzulässig großes Spiel zwischen Oberrolle und Unterrolle gegeben ist, wenn beispielsweise der Schlitten nur noch den letzten (oberen) Teleskopschuß überfährt. Es ist ersichtlich, daß aufgrund des in Abhängigkeit von der Anzahl der verwendeten Teleskopschüsse vorgegebenen Abstandes zwischen Oberrolle und Unterrolle zwangsläufig ein erhebliches Spiel zwischen dem oberen Schenkel der letzten (oberen) Führungsschiene und der Unterrolle eintreten muß, wenn diese auf dem oberen Schenkel der letzten (oberen) Führungsschiene verfahren wird. Dies bedeutet gleichzeitig, daß sich die Unterrolle _ insbesondere mit ihrem Spurkranz _ sehr stark den Sprossen nähert, welche zur Verbindung der unteren Schenkel der _ beispielsweise letzten _ Führungsschiene dienen.In practice, there is difficulty in determining the distance between the lower edge of the upper roller and the upper edge of the lower roller so that _ depending on the number of guide rails to be moved into each other _ there are no constraints between the upper roller and lower roller when the inclined elevator is fully retracted, on the other hand, however, there is no inadmissibly large play between the upper roller and lower roller, for example if the slide only passes over the last (upper) telescopic section. It can be seen that due to the distance between the top roller and the bottom roller depending on the number of telescopic sections used, there must inevitably be considerable play between the upper leg of the last (upper) guide rail and the bottom roller if it is on the top leg of the last ( upper) guide rail is moved. At the same time, this means that the lower roller _ very closely approaches the rungs, which serve to connect the lower legs of the _ for example last _ guide rail, particularly with their flange _.

Aus dem Vorstehendem ergibt sich, daß die Abmessung der letzten (oberen) Führungsschiene zwangsweise vorgegeben ist; ausgehend von der Bemessung dieser letzten Führungssschiene ergeben sich jedoch zwangsläufig die Bemessungen der nachfolgenden Führungsschienen größeren Querschnitts. Damit sind die maximal erreichbaren Aufzugslängen bei Verwendung bestimmter Querschnitte vorgegeben.From the above it follows that the dimension of the last (upper) guide rail is forcibly specified; However, based on the dimensioning of this last guide rail, the dimensioning of the subsequent guide rails of a larger cross section necessarily results. This specifies the maximum achievable elevator lengths when using certain cross sections.

Aufgabe der Erfindng ist es, die wirksame Aufzuglänge bei im wesentlichen gleichem _ also bei dem bisher verwendeten _ Tragrollenabstand unter Beachtung des zulässigen Spiels zu vergrößern bzw. bei Verwendung der gleichen Führungsschienenzahl den Schrägaufzug preiswerter zu gestalten.The object of the invention is to increase the effective elevator length with essentially the same _ that is, with the _ idler roller spacing previously used, taking into account the permissible play, or to make the inclined elevator cheaper when using the same number of guide rails.

Die Erfindung löst die gestellte Aufgabe durch die Lehre nach Anspruch 1. Die Erfindung löst sich somit von der Vorstellung, daß die Oberrolle grundsätzlich als tragendes Element der Oberseite des oberen Schenkels der Führungsschienen aufliegen muß. Durch die zusätzliche Zuordnung einer Stützschiene bei der letzten (oberen) Führungsschiene wird die Unterrolle als tragende Rolle mit einbezogen. Dabei hebt sich die Oberrolle während des Verfahrens über die letzte (obere) Führungsschiene von der Oberseite des oberen Schenkels der letzten Führungsschiene geringfügig ab.The invention solves the problem set by the teaching of claim 1. The invention thus solves the idea that the top roller must fundamentally rest as a supporting element of the top of the upper leg of the guide rails. By additionally assigning a support rail to the last (upper) guide rail, the lower roller is included as a supporting role. The upper roller lifts slightly above the last (upper) guide rail from the top of the upper leg of the last guide rail during the process.

Mit der erfindungsgemäßen Lösung ist es nunmehr möglich, einem beispielsweise aus den Führungsschienen 1-6 (in der Zählung von innen nach außen) gebildeten Schrägaufzug eine Führungsschiene 0 zuzuordnen, welche anstelle der bisherigen Führungsschiene 1 als von Hand ausziehbare letzte Führungsschiene dient. Ein aus den bisherigen Führungsschienen 1-6 gebildeter Schrägaufzug kann somit um eine Führungsschienenlänge, nämlich um die Länge der Führungsschiene 0 verlängert werden, ohne daß die Abmessungen der Führungsschienen 1-6 geändert werden müssen. Hier ergibt sich somit eine zusätzliche Verlängerungsmöglichkeit des Schrägaufzuges.With the solution according to the invention, it is now possible to assign a guide rail 0, which is formed, for example, from the guide rails 1-6 (counting from the inside to the outside), which serves instead of the previous guide rail 1 as a last guide rail which can be pulled out by hand. An inclined elevator formed from the previous guide rails 1-6 can thus a length of the guide rail, namely by the length of the guide rail 0, without the dimensions of the guide rails 1-6 having to be changed. This results in an additional extension option for the inclined elevator.

Andererseits kann _ sofern man auf eine Verlängerung des Schrägaufzuges verzichten will _ ein aus den bisherigen Führungsschienen 1-6 gebildeter Schrägaufzug nunmehr aus den Führungsschienen 0-5 gebildet werden, was zwangsläufig zu einer preiswerteren Ausführungsform führt, da jede der Führungsschienen bei gleicher Auszugslänge um eine Einheit kleiner ausgebildet sein kann.On the other hand _ if you want to do without an extension of the inclined elevator _ an inclined elevator formed from the previous guide rails 1-6 can now be formed from the guide rails 0-5, which inevitably leads to a cheaper embodiment, since each of the guide rails with the same extension length by one Unit can be made smaller.

Die erfindungsgemäß zwischen den Schenkeln des U-Profils und parallel zu diesen verlaufende Stützschiene, deren Oberseite die Lauffläche für die Unterrolle bildet, kann unterschiedlich ausgebildet sein.According to the invention, the support rail, which runs between the legs of the U-profile and runs parallel to them, the upper side of which forms the running surface for the lower roller, can be designed differently.

Vorteilhafte Ausgestaltungen der Erfindung sind durch die Unteransprüche gekennzeichnet.Advantageous embodiments of the invention are characterized by the subclaims.

So ist die Stützschiene vorzugsweise als Hohlprofil ausgebildet, wobei das Hohlprofil entweder als Rechteckrohr ausgebildet sein kann (Anspruch 6) oder gemeinsam mit Teilen des Steges und des unteren Schenkels der U-förmigen Führungsschiene als besonders bevorzugte Ausführungsform ein einstückiges Hohlprofil bildet.Thus, the support rail is preferably designed as a hollow profile, the hollow profile can either be designed as a rectangular tube (claim 6) or together with parts of the web and the lower leg of the U-shaped guide rail forms a one-piece hollow profile as a particularly preferred embodiment.

Dabei kann eine entsprechende Einziehung als Aufnahmetasche für eine Sprosse vorgesehen sein.A corresponding retraction can be provided as a receiving pocket for a rung.

Die Erfindung stellt sich demgemäß nach Anspruch 7 so dar, daß die Führungsschiene gemäß Anspruch 1 die letzte, d.h. die innerste Führungsschiene eines aus mehreren teleskopierbaren Führungsschienen gebildeten Schrägaufzuges bildet, wobei die jeweils oberen Schenkel sämtlicher Führungsschienen _ mit Ausnahme der letzten _ an ihren Oberseiten die Lauffläche für die Oberrollen bilden, während ausschließlich die letzte Führungsschiene eine zwischen den Schenkeln des U-Profils und parallel zu diesen verlaufende Stützschiene aufweist, deren Oberseite die Lauffläche für die Unterrolle bildet.The invention accordingly presents itself according to claim 7, that the guide rail according to claim 1 forms the last, ie the innermost guide rail of an inclined elevator formed from a plurality of telescopic guide rails, the upper legs of all guide rails _ with the exception of the last _ forming the running surface for the upper rollers on their upper sides, while exclusively the last guide rail has a running between the legs of the U-profile and parallel to this support rail, the top of which forms the running surface for the lower roller.

Bei der letzten Führungsschiene handelt es sich vorzugsweise um eine von Hand ausziehbare Schiene; die Erfindung wird jedoch nicht verlassen, wenn die hier in Frage stehende Führungsschiene mit in den aktiv teleskopierbaren Bereich der übrigen Führungsschienen einbezogen wird.The last guide rail is preferably a rail that can be pulled out by hand; However, the invention is not left when the guide rail in question is included in the actively telescopic area of the other guide rails.

Es versteht sich, daß die die unteren Schenkel der zweitletzten Führungsschiene verbindenen Sprossen gegenüber der bekannten Ausführungsform vorteilhaft in ihrer Höhe etwas verringert ausgeführt werden können, um ein unnötig starkes Abheben der Oberrolle zu vermeiden.It goes without saying that the rungs connecting the lower legs of the second to last guide rail can advantageously be of a somewhat reduced height compared to the known embodiment in order to avoid unnecessarily strong lifting of the top roller.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

Aus der Fig. 1 ist ein teilweise im Querschnitt dargestellter Schrägaufzug 7 ersichtlich, welcher im wesentlichen aus den Führungsschienen 1-6 gebildet ist. Die Führungsschiene 1 ist ein etwa U-förmiges Profil mit den Schenkeln b und b′. Die Führungsschienen 2-6 sind etwa gleichartig ausgebidlet, d.h. sie besitzen einen unteren Doppelschenkel entsprechend der Darstellung bei c′ sowie einfache obere Schenkel c-g. Mit 20′ ist eine Sprosse bezeichnet. welche jeweils die unteren Schenkel zueinanderweisender U-Profile verbindet.1 shows an inclined elevator 7, partially shown in cross section, which is essentially formed from the guide rails 1-6. The guide rail 1 is an approximately U-shaped profile with the legs b and b '. The guide rails 2-6 are roughly the same, i.e. they have a lower double leg as shown at c 'and simple upper leg c-g. With 20 'is called a rung. which connects the lower legs of mutually facing U-profiles.

Aus der Fig. 1 ist weiter ersichtlich, daß zwischen der Oberrolle 8 und der Unterrolle 9 ein Freiraum 24 gebildet ist, welcher erforderlich ist, um die Schenkel b-g der Führungsschienen 1-6 aufzunehmen. Die innere Führungsschiene 1 ist eine von Hand ausfahrbare Verlängerungsschiene.From Fig. 1 it can also be seen that a free space 24 is formed between the upper roller 8 and the lower roller 9, which is required to accommodate the legs b-g of the guide rails 1-6. The inner guide rail 1 is an extension rail that can be extended by hand.

Aus der Fig. 1 ist ersichtlich, daß sich beim Verfahren des nicht dargestellten Lastaufnahmemittels der Tragrollensatz 10 automatisch auf die Führungssschiene 1 absenkt, so daß sich nahezu der gesamte Freiraum 24 unterhalb des Schenkels b defindet. Es ist auch erkennbar, daß der Spurkranz 22 der Unterrolle 9 (noch) von dem mit 20′ bezeichneten Quergurt freigeht.From Fig. 1 it can be seen that when moving the load suspension means, not shown, the idler roller set 10 automatically lowers on the guide rail 1, so that almost the entire free space 24 is located below the leg b. It can also be seen that the flange 22 of the lower roller 9 (still) goes free from the cross belt designated 20 '.

Fig. 3 läßt erkennen, daß bei Zuordnung einer weiteren, mit 0′ bezeichneten Führungsschiene, die in ihrem Aufbau der Schiene 1 entspricht, und deren oberer Schenkel zwangsläufig unterhalb der Bezugslinie 21 liegen müßte, der Spurkranz 22 mit der Sprosse 20′ der Schiene kollidiert, daß darüber hinaus aber insbesondere auch keine Möglichkeit mehr bestünde, die unteren Schenkel der Schiene 0′ durch Sprossen 18′′ zu verbinden, weil der Spurkranz 22 bzw. die Unterrolle 9 diese Sprossen 18′′ schneiden würde.Fig. 3 shows that when assigning another, with 0 'designated guide rail, which corresponds in structure to the rail 1, and whose upper leg would necessarily be below the reference line 21, the flange 22 collides with the rung 20' of the rail that beyond that in particular there was no longer any possibility, the lower leg of the rail 0 'by rungs 18 '' to connect because the flange 22 or the lower roller 9 would cut these rungs 18 ''.

Fig. 4 verdeutlich, daß nach der erfindungsgemäßen Lösung die Zuordnung einer Schiene 0 möglich ist. Die nach Fig. 4 dargestellte Führungsschiene 0 ist voll in das bisherige System integrierbar (s. auch Fig. 6-8). Durch die Bildung einer in der Schiene 0 liegenden Stützschiene 11, auf deren Lauffläche 12 sich die Unterrolle 9 abstützen kann, ist es möglich, die Unterrolle 9 bzw. den ihr zugeordneten Spurkranz 22 so weit anzuheben, daß eine ausreichend starke Verbindung zueinanderweisender benachbarter Führungsschienen 0 und 1 durch Sprossen 18 und 20 möglich ist. Dabei hebt sich, wie Fig. 5 ausweist, die Oberrolle 8 unter Bildung eines geringen Spaltes 23 etwas vom oberen Schenkel a der Schiene 0 ab. Fig. 4 veranschaulicht deutlich, daß bei Beibehaltung der Schienen 1-6 durch die Zuordnung der erfindungsgemäßen Schiene 0 der Schrägaufzug um eine Schienenlänge verlängerbar ist. Da es sich bei der Schiene 0 um eine von Hand ausziehbare, im Regelfall auf dem Dach eines Hauses abgestützte Schiene handelt, kann diese hinsichtlich ihrer Wandstärkenbemessung etwas dünner ausgebildet sein, wobei insbesondere die hohlprofilartige Ausbildung der Stützschiene 11 der Führungsschiene 0 eine ausreichende Steifigkeit vermittelt.Fig. 4 shows that the assignment of a rail 0 is possible according to the solution according to the invention. The guide rail 0 shown in FIG. 4 can be fully integrated into the previous system (see also FIGS. 6-8). By forming a support rail 11 lying in the rail 0, on the running surface 12 of which the lower roller 9 can be supported, it is possible to raise the lower roller 9 or the wheel flange 22 associated therewith to such an extent that a sufficiently strong connection of adjacent guide rails 0 and 1 by rungs 18 and 20 is possible. 5, the upper roller 8 lifts somewhat from the upper leg a of the rail 0 to form a small gap 23. Fig. 4 clearly shows that if the rails 1-6 are retained by assigning the rail 0 according to the invention, the inclined lift can be extended by one rail length. Since the rail 0 is a rail that can be pulled out by hand and is usually supported on the roof of a house, this can be made somewhat thinner in terms of its wall thickness dimension, the hollow profile-like design of the support rail 11 of the guide rail 0 in particular imparting sufficient rigidity.

Anhand der Fig. 4 soll nachfolgend verdeutlich werden, welche Abmessungen vorzugsweise Verwendung finden:4, the following is intended to clarify which dimensions are preferably used:

Der Mittenabstand x (s. auch Fig. 6) zwischen Oberrolle und Unterrolle beträgt 69 mm. Der Rollendurchmesser der Unterrolle sowie der Oberrolle beträgt am Rollenfuß, d.h. am Spurkranz 40 mm. Die Schenkeldicke des Schenkels a der Führungsschiene 0 beträgt 3 mm; die Schendeldicke der Schenkel b-g der Führungsschienen 1-6 beträgt jeweils 4 mm. Hinzuzurechnen ist ein Spiel von 2 mm, so daß sich zwischen der Oberrolle 8 und der Unterrolle 9 ein Freiraum von 39 mm ergibt, welcher vollständig durch die Schenkeldicken a-g zuzüglich des Spiels von 2 mm ausgefüllt wird.The center distance x (see also Fig. 6) between the top roller and bottom roller is 69 mm. The roller diameter of the lower roller and the upper roller is 40 mm at the roller base, ie at the wheel flange. The leg thickness of the leg a der Guide rail 0 is 3 mm; the thigh thickness of the legs bg of the guide rails 1-6 is 4 mm in each case. A play of 2 mm is to be added, so that there is a clearance of 39 mm between the upper roll 8 and the lower roll 9, which is completely filled by the leg thicknesses ag plus the play of 2 mm.

Die Zuordnung der Schiene 0 ist somit möglich, ohne den bisher üblichen Mittenabstand x der Rollen bzw. ohne den bisher üblichen Rollendurchmesser y änden zu müssen.The assignment of the rail 0 is thus possible without having to change the previously usual center distance x of the rollers or without changing the previously usual roller diameter y.

Fig. 7 läßt erkenen, daß die Erfindung grundsätzlich bei Verwendung eines Hohlprofiles 14 verwirklicht werden kann, welches als Rechteckrohr 19 ausgebildet ist. Zwischen dem Rechteckrohr 19 und dem unteren Schenkel a′ kann eine mit 18′ bezeichnete Sprosse angeordnet sein.Fig. 7 shows that the invention can basically be implemented using a hollow profile 14 which is designed as a rectangular tube 19. Between the rectangular tube 19 and the lower leg a 'a rung designated 18' can be arranged.

Fig. 8 veranschaulicht ein einstückig hergestelltes Profil für die Schiene 0; hier ist unter Einbeziehung eines Abschnittes des Steges 15 sowie eines Abschnittes des Schenkels a′ ein Hohlprofil 13 gebildet, dessen kürzere Rechteckseite 16 eine mit 17 bezeichnete Einziehung aufweist, welche eine Aufnahmetasche für eine einzuschweißende Sprosse bildet.Fig. 8 illustrates a one-piece profile for the rail 0; here, with the inclusion of a portion of the web 15 and a portion of the leg a ', a hollow profile 13 is formed, the shorter rectangular side 16 of which has a recess 17, which forms a receiving pocket for a rung to be welded in.
