Abstract

A locking device between two or more telescopic elements, movable relative to one another, of a cage or goods lift. Here, the individual telescopic elements are mutually locked by trip-dog carriers or locking pawls. This locking can be designed to occur automatically and to be released by the actuation of a pulling rope or vice versa. The essential feature of the invention is that the rope extension of the pulling rope run over a plurality of telescopic elements is compensated by pulley-block-like turning of the pulling rope, i.e. a substantially greater shortening is effected at reduced expenditure of force in the pulling rope compared with the unlocking or locking rope. Consequently, there is not only a transmission ratio within the pulling rope itself but also between the pulling rope and the locking or unlocking rope. <IMAGE>

Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für die aneinander zwangsgeführten Teleskopschüsse eines Aufzuges, wobei jeder Teleskopschuß als Leiter ausgebildet und mit dem nächstfolgenden Teleskopschuß in mehreren Ausfahrpositionen gegen Einfahren verriegelbar ist und wobei am Ende aller Teleskopschüsse mit Ausnahme eines Teleskopschusses zur Verriegelung seilbetätigte, aus der Ebene eines Teleskopschusses in die Ebene des nächstfolgenden Teleskopschusses federbelastet einschwenkbare Verriegelungsnocken dienen, an denen sich Stützglieder des nächstfolgenden Teleskopschusses abstützen, unter Verwendung von Zugseilen welche an beweglich gelagerten Zwischengliedern angeschlossene Verriegelungsseile betätigen.The invention relates to a locking device for the positively guided telescopic sections of an elevator, wherein each telescopic section is designed as a ladder and can be locked with the next telescopic section in several extended positions against retraction, and at the end of all telescopic sections with the exception of a telescopic section for locking, operated from the level of a telescopic section serve in the plane of the next telescopic section spring-loaded pivoting locking cams, on which support members of the next telescopic section are supported, using traction cables which operate locking cables connected to movably mounted intermediate members.

Es ist eine solche Vorrichtung bei einem Lastaufzug bekannt (DE-PS 30 01 410), wobei der Aufzug eine Schiene zur Führung eines Lastaufzugbehälters aufweist. Bei dem bekannten Lastaufzug fahren bei Betätigung einer Winde mehrere Teleskopschüsse in Relativbewegung zueinander aus. Mittels eines am Bedienungsstand angeordneten Betätigungsmittels kann über ein entsprechendes Zugseil eine Verriegelungsvorrichtung betätigt werden, mit deren Hilfe alle Teleskopschüsse untereinander verriegelt werden. Das "Einlegen" der Verriegelung erfolgt somit über ein handbetätigtes Zugseil; nachdem die Verriegelung durch das gleiche Zugseil aufgehoben wurde, verbleibt die Verriegelungsvorrichtung federbelastet in der entriegelten Position. Zur Übertragung des Seilzuges von einem Teleskopschuß auf den anderen finden Schwenkkörper Verwendung, die nur eine geringe "Einkürzung" des jeweiligen Seiles zulassen. Dabei wurde es als nachteilig empfunden, daß eine erhebliche Kraft zur Betätigung der schwenkbaren Körper aufgewendet werden mußte, während gleichzeitig nur eine geringe Einkürzung des Zugseiles möglich war. Dies bedingte ein ungenaues Ansprechen der Verriegelung, weil die durch den schwenkbaren Körper verursachte Seileinkürzung weitgehend durch die Seildehnung des gegenüber dem Verriegelungsseil wesentlich längeren Zugseiles kompensiert wurde. Diese starke Seildehnung ist bei dem kürzeren Verriegelungsseil nicht gegeben.Such a device is known for a freight elevator (DE-PS 30 01 410), the elevator being a rail for Has leadership of a freight elevator container. In the known goods lift, several telescopic shots extend relative to one another when a winch is actuated. By means of an actuating means arranged on the control station, a locking device can be actuated via a corresponding pull rope, with the aid of which all telescopic sections are locked together. The "insertion" of the locking is done via a manually operated pull rope; after the lock has been released by the same pull rope, the locking device remains spring-loaded in the unlocked position. Swivel bodies are used to transfer the cable pull from one telescopic section to the other, which allow only a slight "shortening" of the respective cable. It was perceived as a disadvantage that a considerable force had to be used to actuate the swiveling bodies, while at the same time only a slight shortening of the pulling rope was possible. This necessitated an imprecise response of the locking device, because the shortening of the rope caused by the pivotable body was largely compensated for by the rope stretching of the pulling rope, which was considerably longer than the locking rope. This strong rope elongation is not the case with the shorter locking rope.

Durch die DE-OS 25 19 513 ist eine Schiebeleiter bekannt geworden, welche aus einer Unterleiter und einer Oberleiter besteht und wobei die Verschiebung der beiden Leiterteile zueinander ebenfalls seilbetätigt, jedoch von Hand erfolgt. Dabei ist an der in Ruhe verbleibenden Unterleiter ein schwenkbarer Einfallhebel gelagert, welcher zum Zwecke der Abstützung der Oberleiter zweiarmig ausgebildet ist und mit der Stützfläche eines Armes unter einen Holm der Unterleiter und der Stützfläche des anderen Armes unter den jeweiligen Holm der Oberleiter faßt. Beim Verschieben der Oberleiter im Ausfahrsinne kann der Einfallhebel gegen die Kraft einer Feder ausweichen. Zum Zwecke der Entriegelung muß das Zugseil in eine seitlich von der Unterleiter befindliche Position verbracht werden. Hier handelt es sich also nicht um eine Verriegelung für die Teleskopschüsse eines Aufzuges; außerdem ist auch hier zunächst eine Druckentlastung der Verriegelungsvorrichtung (Auffahren der Oberleiter um ein bestimmtes Maß) erforderlich, damit die Verriegelungsvorrichtung in die entriegelte Stellung schwenken kann. Die Vorrichtung nach der DE-OS 25 19 513 ist deshalb nur bei relativ leichten Schiebeleitern anwendbar.From DE-OS 25 19 513 a sliding ladder has become known which consists of a lower ladder and an upper ladder and the displacement of the two ladder parts to one another is also rope-operated, but is done by hand. In this case, a pivotable drop lever is mounted on the resting sub-conductor, which is designed with two arms for the purpose of supporting the upper conductor and with the support surface of one arm under a spar of the sub-conductor and the support surface of the other arm under the holds the respective spar of the top ladder. When the upper conductor is moved in the direction of extension, the drop lever can deflect against the force of a spring. For the purpose of unlocking, the pull rope must be moved to a position to the side of the lower conductor. So this is not a lock for the telescopic shots of an elevator; in addition, a pressure relief of the locking device (opening of the upper conductor by a certain amount) is also necessary here so that the locking device can pivot into the unlocked position. The device according to DE-OS 25 19 513 can therefore only be used with relatively light extension ladders.

Die Erfindung geht von dem Std. d. T. nach der Verriegelungsvorrichtung gemäß DE-PS 30 01 410 aus. Ihr liegt die Aufgabe zugrunde, die Verriegelungsvorrichtung noch einfacher und zuverlässiger zu gestalten. Die zur Betätigung der Verriegelungsvorrichtung erforderliche Seilführung soll so gestaltet werden, daß ein zuverlässiges Ansprechen des Entriegelungsseiles und damit der Entriegelungsvorrichtung gewährleistet ist. Gleichzeitig soll erreicht werden, daß zur Betätigung der Verriegelungsvorrichtung möglichst wenig Kraftaufwand erforderlich ist. Die unterschiedliche Länge des Zugseiles einerseits und des Verriegelungsseiles andererseits und die damit gegebene unterschiedliche Seillängung unter Spannung soll quasi durch eine "Übersetzung" zwischen den beiden Seilen kompensiert werden.The invention is based on the std. T. after the locking device according to DE-PS 30 01 410. It is based on the task of making the locking device even simpler and more reliable. The cable guide required to operate the locking device should be designed so that a reliable response of the unlocking cable and thus the unlocking device is guaranteed. At the same time, it should be achieved that as little force as possible is required to actuate the locking device. The different lengths of the traction rope on the one hand and the locking rope on the other hand and the resulting different rope elongation under tension should be compensated for by a "translation" between the two ropes.

Die Erfindung löst die gestellte Aufgabe bei einer Verriegelungsvorrichtung der eingangs genannten Gattung durch die Lehre des Anspruches 1.The invention achieves the stated object in a locking device of the type mentioned at the outset by the teaching of claim 1.

Nach der erfindungsgemäßen Lösung ist die bewegliche Rolle direkt oder indirekt über das Ver- oder Entriegelunsseil mit den zwischen die einzelnen Teleskopschüsse einfassenden Verriegelungselementen (Verriegelungsnocken, Sperrklinken) verbunden, während das Zugseil flaschenzugartig um eine feste Rolle und eine bewegliche Rolle herumgeführt ist. Auf diese Weise erfährt das Zugseil zunächst selbst eine "Übersetzung" hinsichtlich seiner Bewegung, d.h. das zum einen längere und gegebenenfalls über mehr Umlenkstellen geführte Zugseil erfährt eine größere Längenänderung als das Ver- bzw. Entriegelungsseil. Damit findet eine weitere Übersetzung zwischen dem Zugseil und dem Ver- bzw. Entriegelungsseil statt. Infolge der flaschenzugartigen Umlenkung des Zugseiles muß somit nur ein geringer Zug auf dieses ausgeübt werden, um das Ver- bzw. Entriegelungsseil zu betätigen. Durch die größere Veränderung der wirksamen Länge des Zugseiles wird die Seilelastizität und die "Lose" in den Umlenkstellen besser kompensiert. Im Ergebnis wird eine zuverlässigere und einfachere Bedienung der Entriegelung verwirklicht.According to the solution according to the invention, the movable roller is directly or indirectly via the locking or unlocking rope connected to the locking elements between the individual telescopic sections (locking cams, pawls), while the pull rope is guided in a pulley-like manner around a fixed roller and a movable roller. In this way, the traction rope itself first experiences a "translation" with regard to its movement, ie the traction rope, which is on the one hand longer and possibly guided over more deflection points, experiences a greater change in length than the locking or unlocking rope. This results in a further translation between the pull rope and the locking or unlocking rope. As a result of the pulley-like deflection of the pull rope, only a slight pull has to be exerted on it to actuate the locking or unlocking rope. Due to the greater change in the effective length of the pull rope, the rope elasticity and the "loose" in the deflection points are better compensated. As a result, a more reliable and simple operation of the unlocking is realized.

Bei Verwendung von Sperrklinken befinden sich diese jeweils am (relativ) ausfahrenden Teleskopschuß und überfahren den (relativ) ruhenden Teleskopschuß derart, daß sie sich mit ihrer Stützfläche jeweils von oben her auf der Sprosse des (relativ) ruhenden Teleskopschusses abstützen. Das Verriegeln erfolgt in an sich bekannter Weise automatisch federbelastet; das Entriegeln hingegen durch die besondere Ausbildung der beweglich gelagerten Zwischenglieder als Flaschenzug in Verbindung mit der Anbindung des Entriegelungsseiles an diesen Flaschenzug. Eine derartige Vorrichtung hat sich nicht nur bei Schrägaufzügen, sondern insbesondere auch bei Gerüstaufzügen bewährt.When using pawls, these are each located on the (relatively) extending telescopic section and run over the (relatively) stationary telescopic section in such a way that their supporting surface is supported from above on the rung of the (relatively) stationary telescopic section. The locking takes place automatically in a manner known per se; unlocking, however, through the special design of the movably mounted intermediate links as a pulley block in connection with the connection of the unlocking rope to this pulley block. Such a device has proven itself not only in inclined lifts, but in particular also in scaffold lifts.

Die Ausbildung der Zwischenglieder als Flaschenzug gewährleistet bei geringem Kraftaufwand weiter eine zuverlässige Übertragung der Seillängenänderung auf die nachfolgenden Teleskopschüsse.The design of the intermediate links as a pulley block ensures that the change in rope length is reliably transmitted to the subsequent telescopic sections with little effort.

Nach der erfindungsgemäßen Lösung kann die bewegliche Rolle des Flaschenzuges direkt oder indirekt auf das Ver- oder Entriegelungsseil einwirken, wobei als Verriegelungsvorrichtung im oberen Bereich der Teleskopschüsse angeordnete Verriegelungsnocken oder im unteren Bereich der Teleskopschüsse angeordnete Sperrklinken Verwendung finden können. Die Verriegelungsnocken können nach einem älteren Vorschlag der Anmelderin an einer gegen Federkraft in die Entriegelungsposition ausweichenden Steuerkurve angeordnet sein oder unter Federkraft in Entriegelungsposition ausschwenken. Die Sperrklinken hingegen fallen bevorzugt federbelastet in die Verriegelungsposition ein und werden mittels des Zugseiles in die Entriegelungsposition verbracht.According to the solution according to the invention, the movable roller of the pulley block can act directly or indirectly on the locking or unlocking rope, locking cams arranged in the upper region of the telescopic sections or pawls arranged in the lower region of the telescopic sections can be used. According to an older proposal by the applicant, the locking cams can be arranged on a control cam which deflects into the unlocking position against spring force or can pivot out under spring force in the unlocking position. The pawls, on the other hand, preferably spring-loaded into the locking position and are brought into the unlocking position by means of the pull rope.

In vorteilhafter Ausgestaltung gemäß Anspruch 2 ist es nunmehr lediglich erforderlich, daß am Bedienungsstand manuell die Verriegelung "eingelegt" wird. Die Verriegelung rastet dabei zwischen die Stützglieder (z.B. die Sprossen) aller (nächstfolgenden) Teleskopschüsse ein. Beim weiteren Ausfahren des nächstfolgenden Teleskopschusses ist jedoch vom Bedienungsstand her keine Entriegelung erforderlich; diese Entriegelung erfolgt automatisch durch die die Stütznocken überlaufenden Sprossen des zweiten Teleskopschusses und rastet ebenso automatisch nach dem Überlaufen wieder ein, so daß jederzeit die Sicherheit gegen ungewolltes Einfahren der Teleskopschüsse zueinander gewährleistet ist. Es versteht sich, daß der Abstand zwischen zwei Sprossen so groß sein muß, daß ein Einrasten der Stütznocken zwischen die Sprossen ermöglicht wird. Erst durch eine zusätzliche Maßnahme vom Bedienungsstand her - wie dies aus der gattungsbildenden Offenlegungsschrift bekannt ist - wird die Entriegelung vorgenommen und ein Einfahren der Teleskopschüsse zueinander ermöglicht. Es entfällt somit das bisher bei jeder Verlängerung des Teleskopauslegers erforderliche Entriegeln und wieder Verriegeln von Hand vom Bedienungsstand aus. Damit werden weiter die Bedienung vereinfacht und die Sicherheit erhöht.In an advantageous embodiment according to claim 2, it is now only necessary that the lock is "inserted" manually at the control panel. The lock snaps between the support members (e.g. the rungs) of all (next) telescopic sections. When the next telescopic shot is extended further, no unlocking is required from the control station; this unlocking is carried out automatically by the rungs of the second telescopic section overflowing the support cams and also automatically locks again after overflowing, so that safety against unintentional retraction of the telescopic sections is ensured at all times. It is understood that the distance between two rungs must be large enough to allow the support cams to snap into place between the rungs. Only by means of an additional measure from the control station - as is known from the generic disclosure - is the unlocking carried out and the telescopic sections retracted towards each other. There is thus no longer any need to unlock and then lock again manually from the control station with each extension of the telescopic boom. This further simplifies operation and increases security.

Weitere Merkmale der Erfindung sind durch die Unteransprüche gekennzeichnet.Further features of the invention are characterized by the subclaims.

Gemäß Anspruch 3 kann die bewegliche Rolle dieses Flaschenzuges in ihrer Lage durch ein Zugseil verändert werden, so daß hierdurch eine Entriegelung bewirkt wird. Das Zugseil wirkt also über die bewegliche Rolle unmittelbar auf das Entriegelungsseil.According to claim 3, the movable role of this pulley can be changed in position by a pull rope, so that an unlocking is effected. The pull rope thus acts directly on the unlocking rope via the movable roller.

Gemäß Anspruch 4 ist die Seilführung so getroffen, daß sich der auf das Zugseil ausgeübte Zug infolge der Übersetzung auf die jeweils nachfolgenden Zugseile in gleichem Maße überträgt. Hier ist die Übersetzung deswegen besonders vorteilhaft, weil sich die Seillängen und die "Lose " der einzelnen Umlenkpunkte gewissermaßen addieren und durch die Übersetzung ausreichend kompensiert werden können.According to claim 4, the cable guide is made such that the train exerted on the traction cable is transmitted to the same extent as a result of the translation to the following traction cables. The translation is particularly advantageous here because the rope lengths and the "slack" of the individual deflection points add up to a certain extent and can be adequately compensated for by the translation.

Gemäß Anspruch 5 können die Sperrklinken mit relativ kurzen Abweiserflächen die Sprossen des benachbarten Teleskopschusses überlaufen und nach Überlaufen der Sprossen automatisch in die Verriegelungsstellung einfallen. Die Anschläge nach Anspruch 5 begrenzen sowohl das Einfallen im Verriegelungssinne als auch die Schwenkbewegung im Entriegelungssinne durch das Entriegelungsseil.According to claim 5, the pawls with relatively short deflector surfaces can overflow the rungs of the adjacent telescopic section and automatically fall into the locking position after the rungs have overrun. The stops according to claim 5 limit both the falling in the locking direction and the pivoting movement in the unlocking direction by the unlocking cable.

Anspruch 6 beinhaltet die zusätzliche Verwendung des Lagerzapfens der Sperrklinke als Lager für die Verriegelungsfeder zur automatischen Einschwenkung der Sperrklinke in die Verriegelungsstellung; die Feder ist dabei so ausgelegt, daß bei entsprechendem Zug im Entriegelungsseil die Kraft der Verriegelungsfeder überwunden wird und die Verriegelungsvorrichtung im Sinne "Entsperren" betätigt werden kann.Claim 6 includes the additional use of the bearing pin of the pawl as a bearing for the locking spring for automatically pivoting the pawl into the locking position; the spring is designed so that the force of the locking spring is overcome with a corresponding train in the unlocking rope and the locking device can be operated in the sense of "unlocking".

Die Ansprüche 9 und 10 betreffen die Anordnung des Entriegelungsseiles in Verbindung mit einer in das Entriegelungsseil eingeschalteten Zugfeder, welche dem Ausgleich der Seilspannung dient.Claims 9 and 10 relate to the arrangement of the unlocking rope in connection with a tension spring switched into the unlocking rope, which serves to compensate the rope tension.

Die Ansprüche 11 und 12 richten sich auf die Ausbildung der Sperrklinke. Es genügt grundsätzlich, wenn die Verriegelungsvorrichtung nur eine Sperrklinke aufweist, so daß nach Ueberlaufen einer Sprosse die Sperrvorrichtung einfällt. Um jedoch beim Zurücklegen nur kleinerer Ausfahrwege sofort wirksam verriegeln zu können, schlägt die Erfindung weiter vor, daß die Sperrklinke mehrere Verriegelungsnocken aufweist, die in Schwinghebeln an der Schiene des Teleskopschusses gelagert sind. Die Sperrklinke ist also sägezahnartig ausgebildet, wobei jeweils nach Ueberfahren eines Sägezahnes die Verriegelung wirksam einfälltThe claims 11 and 12 are directed to the formation of the pawl. It is generally sufficient if the locking device has only one pawl, so that the locking device engages after a rung has passed. However, in order to be able to immediately lock effectively when traveling only smaller extension paths, the invention further proposes that the pawl has a plurality of locking cams which are mounted in rocker arms on the rail of the telescopic section. The pawl is thus sawtooth-like, with the locking system effectively engaging each time a sawtooth is passed over

Die Erfindung beschränkt sich nicht auf die Verwendung bei als Schrägaufzüge ausgebildeten Lastenaufzügen, sondern zielt insbesondere auf die Verwendung von Gerüstaufzügen ab, bei denen der jeweils ausfahrende Teleskopschuß gemeinsam mit allen folgenden Teleskopschüssen als "Paket" ausfährt, d.h. ohne daß hierbei eine gleichzeitige Relativbewegung der folgenden Schüsse untereinander erfolgt.The invention is not limited to use with freight elevators designed as inclined elevators, but instead aims in particular at the use of scaffolding lifts, in which the telescopic section that extends in each case extends together with all subsequent telescopic sections as a “package”, ie without a simultaneous relative movement of the following sections among themselves.

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

Nach dem Ausführungsbeispiel ist die mit 34 bezeichnete Verriegelungsvorrichtung jeweils im Bereich des unteren Endes 37', 37'', 37''' und 37'''' der Teleskopschüsse IV, III, II und I angeordnet. Aus der Fig. 6 ist ersichtlich, daß dem letzten (untersten) Teleskopschuß die Bezugszahl V zugeordnet wurde, den jeweils folgenden Teleskopschüssen die Bezeichnungen IV, III, II und I in Reihenfolge.According to the embodiment, the locking device designated 34 is in each case Area of the lower end 37 ', 37'',37''' and 37 '''' of the telescopic sections IV, III, II and I arranged. From Fig. 6 it can be seen that the last (lowest) telescopic section has been assigned the reference number V, the following telescopic sections the designations IV, III, II and I in sequence.

Aus der Fig. 6 ist auch erkennbar, daß das mit 53 bezeichnete Zugseil, welches im Bereich des unteren Endes 37 des Teleskopschusses V mit einem Handhebel 54 verbunden ist, bis zu einer Umlenkrolle 55 im Bereich des oberen Endes 38 des Teleskopschusses V geführt und weiter bis zu einer beweglichen Rolle 50 eines Flaschenzuges 52 verlängert ist, welcher aus der beweglichen Rolle 50 und der festen Rolle 51 besteht. Diese beiden vorgenannten Rollen werden von einem weiteren Zugseil 53' umschlungen, welches mit seinem einen Ende in der vorbeschriebenen Weise zum oberen Ende 38' des Teleskopschusses zu geführt ist und mit seinem anderen Ende zum unteren Ende 37' des Teleskopschusses IV verläuft, wo es über eine Spanneinrichtung 56 (s. auch Fig. 1) festgelegt ist.From Fig. 6 it can also be seen that the traction cable designated 53, which is connected in the region of the lower end 37 of the telescopic section V with a hand lever 54, is guided up to a deflection roller 55 in the region of the upper end 38 of the telescopic section V and on is extended to a movable roller 50 of a block and tackle 52, which consists of the movable roller 50 and the fixed roller 51. These two aforementioned roles are wrapped by a further traction rope 53 ', which is led with one end in the manner described above to the upper end 38' of the telescopic section and with its other end to the lower end 37 'of the telescopic section IV, where it runs over a tensioning device 56 (see also FIG. 1) is fixed.

Aus der Fig. 6 ist weiter in der schematischen Darstellung erkennbar, daß an der beweglichen Rolle 50 das eigentliche Entriegelungsseil 46 angreift, welches bei Betätigen des Zugseiles 53' die Verriegelungsvorrichtung im Sinne von "Entriegeln" betätigt.From Fig. 6 it can also be seen in the schematic representation that the actual unlocking rope 46 acts on the movable roller 50, which actuates the locking device in the sense of "unlocking" when the pull rope 53 'is actuated.

Aus der Fig. 6 ist somit erkennbar, daß bei Betätigen des Handhebels 54 in Pfeilrichtung 57 der Zug auf das Seil 53 über die Umlenkrolle 55 auf die bewegliche Rolle 50 und damit auf das Seil 53' übertragen wird. Dieses wird seinerseits die bewegliche Rolle 50 des Teleskopschusses IV verlagern, so daß die Verriegelung 34 durch das Entriegelungsseil 46 aufgehoben wird. Der auf das Zugseil 53 ausgeübte Zug wirkt sich somit auf alle an den oberen Enden 38 - 38'''' der Teleskopschüsse I - V über die Umlenkrollen 55 geführten Zugseile 53' - 53'''' und somit auf die zugehörigen Entriegelungsseile 46 - 46''' aus.From FIG. 6 it can thus be seen that when the hand lever 54 is actuated in the direction of arrow 57, the train is transmitted to the rope 53 via the deflection roller 55 to the movable roller 50 and thus to the rope 53 '. This in turn will shift the movable roller 50 of the telescopic section IV, so that the lock 34 through the unlocking rope 46 is canceled. The tension exerted on the pull rope 53 thus affects all pull ropes 53 '- 53''''at the upper ends 38 - 38''''of the telescopic sections I - V via the deflection rollers 55 and thus on the associated unlocking ropes 46 - 46 '''off.

Aus der Fig. 1 ist die Seilführung in vergrößerter Darstellung ersichtlich. In der Bildebene oben ist das obere Ende 38' des Teleskopschusses IV dargestellt. Das von dem vorhergehenden Teleskopschuß V kommende Zugseil 53' umläuft die Umlenkrolle 55, welche drehbar, jedoch abstandsunveränderlich an einem Quergurt 59 des Teleskopschusses IV angeordnet ist. Das Seil ist weiter zur beweglichen Rolle 50 geführt. Im Bereich der Achse 58 der beweglichen Rolle 50 ist das Entriegelungsseil 46 angeschlossen, welches - was aus der Fig. 5 nicht erkennbar ist - zum unteren Ende des Teleskopschusses IV geführt und über die Feder 47 dort an der Achse 39 angeschlagen ist.The cable guide can be seen in an enlarged view from FIG. 1. The upper end 38 'of the telescopic section IV is shown in the image plane at the top. The pulling rope 53 'coming from the previous telescopic section V rotates around the deflection roller 55, which is arranged on a cross belt 59 of the telescopic section IV so that it can rotate, but does not vary in distance. The rope is guided to the movable roller 50. In the area of the axis 58 of the movable roller 50, the unlocking cable 46 is connected, which - which cannot be seen in FIG. 5 - leads to the lower end of the telescopic section IV and is attached to the axis 39 there by the spring 47.

Die an einer Sprosse 60 des Teleskopschusses IV angeordnete feste Rolle 51 bildet zusammen mit der beweglichen Rolle 50 einen Flaschenzug 52. Beide Rollen werden von einem Seil 53'' umschlungen, welches mit seinem nach oben verlaufenden Ende (s. auch Fig. 6) zum oberen Ende 38'' des Teleskopschusses III und mit seinem nach unten gerichteten Ende zum unteren Ende 37'' des Teleskopschusses III verläuft, wie in der Bildebene der Fig. 1 unten dargestellt. Aus der Fig. 1 ist weiter erkennbar, daß das Entriegelungsseil 46' über eine Feder 47 an der Achse 39 angreift. Die Achse 39 verbindet die beiden Sperrklinken 35, welche auf kurzen, an den Schienen 42 befestigten Lagerzapfen 43 verlagert sind. Die Lagerzapfen 43 befinden sich unterhalb des untersten Quergurtes 44 des Teleskopschusses. Eine auf einer Verlängerung des Lagerzapfens 43 angeordnete Verriegelungsfeder 45 stützt sich einerseits an dem Quergurt 44 und andererseits an als Sperrklinken 35 ausgebildeten Verriegelungsnocken 62 die Sperrklinke in Verriegelungsposition. An den Sperrklinken angeordnete Anschläge 40, die sich gegen die Schienen 42 legen, verhindern ein zu weites Durchschwenken der Sperrklinken aufgrund der Kraft der Feder 45.The fixed roller 51 arranged on a rung 60 of the telescopic section IV forms, together with the movable roller 50, a pulley 52. Both rollers are wrapped in a rope 53 ″, which ends with its upward end (see also FIG. 6) The upper end 38 ″ of the telescopic section III and with its downward end to the lower end 37 ″ of the telescopic section III, as shown in the image plane of FIG. 1 below. From Fig. 1 it can also be seen that the unlocking rope 46 'acts on the axis 39 via a spring 47. The axis 39 connects the two pawls 35, which are displaced on short bearing pins 43 fastened to the rails 42. The journals 43 are located below the lowest cross belt 44 of the telescopic section. A locking spring arranged on an extension of the bearing pin 43 45 is supported on the one hand on the cross belt 44 and on the other hand on locking cams 62 designed as pawls 35, the pawl in the locking position. Stops 40 arranged on the pawls, which lie against the rails 42, prevent the pawls from swinging too far due to the force of the spring 45.

Wie aus der Fig. 2 erkennbar, weist die Sperrklinke eine Gleitfläche 61 auf, mit der sie beim Überfahren des benachbarten Teleskopschusses an den Sprossen 60 des benachbarten Schusses entgegen der Wirkung der Feder 45 entlanggleiten kann. Aus Fig. 4 ist auch ersichtlich, daß ein zusätzlicher Anschlag 41 vorgesehen ist, der ein zu weites Durchschwenken der Sperrklinken bei Betätigung des Entriegelungsseiles 46' verhindern soll.As can be seen from FIG. 2, the pawl has a sliding surface 61, with which it can slide along the rungs 60 of the adjacent shot against the action of the spring 45 when the neighboring telescopic shot is passed over it. From Fig. 4 it can also be seen that an additional stop 41 is provided which is intended to prevent the pawls from swinging too far when the unlocking rope 46 'is actuated.

In der verriegelten Stellung nimmt die Sperrklinke die in Fig. 3 dargestellte Position ein.In the locked position, the pawl assumes the position shown in FIG. 3.

In der Fig. 5 ist mit 36 eine abgewandelte Ausführungsform der Sperrklinke bezeichnet. Hiernach ist eine sägezahnartig ausgebildete Sperrklinke, welche mehrere Verriegelungsnocken 48 aufweist, in Schwinghebeln 49 derart gelagert, daß die gesamte Sperrklinke über die Schwinghebel beim Ausfahren des Teleskopschusses aus der Ebene des benachbarten Teleskopschusses ausweichen kann. Nach Überfahren einer Sprosse kann die Sperrklinke in der vorbeschriebenen Weise im Verriegelungssinne einfallen. Es ist ersichtlich, daß eine derartig ausgebildete Sperrklinke vorzugsweise in dem Freiraum zwischen dem untersten Quergurt 44 und der nächstfolgenden Sprosse eingebaut wird. Sie hat den Vorteil, daß bei Zurücklegen eines nur geringen Ausfahrweges die Sperrvorrichtung jeweils einfällt.5, a modified embodiment of the pawl is designated by 36. According to this, a sawtooth-shaped pawl, which has a plurality of locking cams 48, is mounted in rocker arms 49 in such a way that the entire pawl can move out of the plane of the adjacent telescopic shot when the telescopic shot is extended. After driving over a rung, the pawl can engage in the locking sense in the manner described above. It can be seen that a pawl of this type is preferably installed in the space between the lowermost cross belt 44 and the next rung. It has the advantage that the locking device engages each time a small extension path is covered.
