Abstract

A clamp (1) for a safe-climbing device having a vertically arranged guide rail (2) consists of a basic body (4) which has, at its outer end projecting relative to the guide rail (2), a stop (5) for an intermediate connection for connecting a take-up belt and, in the region of its other end (6), inner and outer guide elements (7, 8) holding the basic body (4) on the guide rail (2), and which can be pivoted, about a horizontal axis perpendicular to the horizontal longitudinal extension of the basic body (4), out of a movement position, in which it is movable along the guide rail (2) by means of the guide elements (7, 8), into a blocking position, in which it can be supported by means of a locking nose (9) on one of a plurality of in-line projections (10) of the guide rail (2). Such a clamp (1) provides a design which is substantially simpler in handling terms if there is mounted movably at said other end (6) of the basic body (4) a locking-nose carrier (11) which changes automatically as a result of gravity into an operating position, in which the locking nose (9) is located directly in front of the projections (10) of the guide rail (2) in the movement position of the basic body (4). The locking-nose carrier (11) is preferably designed as a bolt which is mounted freely displaceably in a vertical recess (12) provided at the other end (6) of the basic body (4) and which is equipped with a locking nose (9) at each of its two ends. <IMAGE>

Description

Die Erfindung betrifft eine Fangeinrichtung für eine Steig­schutzeinrichtung mit einer vertikal angeordneten Führungs­schiene, bestehend aus einem Grundkörper, der an seinem ge­genüber der Führungsschiene vorkragenden Außenende einen An­schlag für eine Zwischenverbindung zum Anschluß eines Auf­fanggurtes und im Bereich seines anderen Endes den Grundkör­per an der Führungsschiene haltende innere und äußere Füh­rungselemente aufweist und der um eine zur horizontalen Längserstreckung des Grundkörpers senkrechte Horizontalachse aus einer Bewegungsstellung, in der er mit den Führungsele­menten längs der Führungsschiene bewegbar ist, in eine Sperr­stellung verschwenkbar ist, in der er mit einer Verriege­lungsnase an einem von mehreren gereihten Ansätzen der Füh­rungsschiene abstützbar ist.The invention relates to a fall arrester for a fall arrest device with a vertically arranged guide rail, consisting of a base body which, at its outer end projecting from the guide rail, has a stop for an intermediate connection for connecting a safety harness and in the region of its other end the inner body holding the base body on the guide rail and has outer guide elements and which can be pivoted about a horizontal axis perpendicular to the horizontal longitudinal extension of the base body from a movement position in which it can be moved along the guide rail with the guide elements into a locking position in which it is locked with one of the several approaches of the guide rail with a locking lug is supported.

Bei einer bekannten Fangeinrichtung der genannten Art (DE-U-­88 13 567) wird die Verriegelungsnase vom unteren Bereich des genannten anderen Endes des Grundkörpers gebildet. Diese Verriegelungsnase weist in Bewegungsstellung des Grundkör­pers einen verhältnismäßig großen Abstand von den Ansätzen der Führungsschiene auf. Der Vorteil dieser bekannten Fang­einrichtung besteht darin, daß das Steigen auch ohne die so­genannte Rückenlage möglich ist, mit der ansonsten der Grund­körper in Bewegungsstellung zu halten ist. Nachteilig ist aber, daß zum Abstützen der Verriegelungsnase auf einem der Ansätze der Führungsschiene am Anschlag des Grundkörpers ei­ne verhältnismäßig große, nach unten gerichtete Kraft angrei­ fen muß. Hierdurch ist bei einem Absturz ein sofortiges Fan­gen nicht immer gewährleistet. Störend ist bei der bekannten Fangeinrichtung außerdem, daß aufgrund der fehlenden Symme­trie sowohl an der Fangeinrichtung als auch an der Führungs­schiene besondere Vorkehrungen getroffen sein müssen, damit der Grundkörper nur in der zutreffenden Stellung in die Füh­rungsschiene eingeführt werden kann.In a known catching device of the type mentioned (DE-U-88 13 567), the locking lug is formed by the lower region of the other end of the base body. This locking lug is in the moving position of the base body at a relatively large distance from the approaches of the guide rail. The advantage of this known catching device is that climbing is also possible without the so-called supine position, with which the base body is otherwise to be kept in the moving position. The disadvantage, however, is that a relatively large, downward force is applied to support the locking lug on one of the approaches of the guide rail at the stop of the base body must. As a result, immediate catching is not always guaranteed in the event of a crash. It is also a problem with the known safety gear that due to the lack of symmetry, special precautions must be taken both on the safety gear and on the guide rail so that the base body can only be inserted into the guide rail in the correct position.

Der Erfindung liegt die Aufgabe zugrunde, eine Fangeinrich­tung anzugeben, bei der es gleichgültig ist, in welcher der beiden um 180° gedrehten Stellungen der Grundkörper in die Führungsschiene eingeführt wird, gleichwohl aber immer ein sofortiges Fangen gewährleistet ist.The invention has for its object to provide a catching device in which it is immaterial in which of the two positions rotated by 180 ° the base body is inserted into the guide rail, but nevertheless an immediate catching is always guaranteed.

Hierzu lehrt die vorliegende Erfindung, daß am genannten an­deren Ende des Grundkörpers ein Verriegelungsnasenträger be­wegbar gelagert ist, welcher durch Schwerkraft selbsttätig in eine Funktionsstellung übergeht, in der die Verriegelungs­nase in Bewegungsstellung des Grundkörpers unmittelbar vor den Ansätzen der Führungsschiene liegt.For this purpose, the present invention teaches that a locking lug carrier is movably mounted at the other end of the base body, which by gravity automatically changes into a functional position in which the locking lug is in the moving position of the base body immediately in front of the approaches of the guide rail.

Die Erfindung geht hierbei von der Erkenntnis aus, daß der bewegbar am Grundkörper gelagerte Verriegelungsnasenträger in der jeweiligen Einführungsstellung automatisch sicher­stellt, daß die Verriegelungsnase in ihre zutreffende Stel­lung gelangt. Zugleich kann hierdurch sichergestellt werden, daß die Verriegelungsnase so nahe an den Ansätzen verläuft, daß bei geringsten Verschwenkungen des Grundkörpers aus der Bewegungsstellung die Sperrung zum Tragen kommt.The invention is based on the finding that the locking lug carrier movably mounted on the base body automatically ensures in the respective insertion position that the locking lug comes into its correct position. At the same time, this can ensure that the locking lug extends so close to the lugs that the lock comes into play with the slightest pivoting of the base body from the movement position.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfin­dung mehrere Möglichkeiten. So besteht der Verriegelungsna­senträger nach einer bevorzugten Ausführungsform aus einem Riegel, der in einer am anderen Ende des Grundkörpers vorge­sehenen Vertikalausnehmung frei verschiebbar gelagert ist und an seinen beiden Enden mit jeweils einer Verriegelungsnase versehen ist; das ist von der Konstruktion her einfach und im Gebrauch besonders zuverlässig. Um beim Benutzer jeden Zweifel über die richtige Benutzungsweise zu beseitigen, empfiehlt es sich, den Riegel bezogen auf eine zu seiner Längserstreckung senkrechte Ebene symmetrisch auszubilden. Zweckmäßigerweise ist der Riegel mit Trägeransätzen im Grund­körper gehalten, so daß er nicht verloren gehen kann und darüber hinaus immer eindeutige Funktionsstellungen gewähr­leistet sind. Schließlich empfiehlt die Erfindung, daß der Riegel zu den Ansätzen der Führungsschiene hin konvex ge­krümmt ist, damit die Konstruktion insgesamt nicht zu schwer wird. Da Fangeinrichtungen oftmals auch unter rauhen Einsatz­bedingungen, beispielsweise mit Schmutz, eingesetzt werden, sollte der Riegel an seinen mit dem Grundkörper in Berührung kommenden Flächen zumindest teilweise mit Rastmarken versehen sein, die im Zuge der Riegelbewegung einen gewissen Selbst­reiningungseffekt bewirken.There are several possibilities for the further configuration within the scope of the invention. Thus, according to a preferred embodiment, the locking lug carrier consists of a bolt which is freely displaceably mounted in a vertical recess provided at the other end of the base body and is provided with a locking lug at both ends thereof; This is simple in construction and particularly reliable in use. In order to remove any doubts from the user about the correct mode of use, it is advisable to design the bolt symmetrically with respect to a plane perpendicular to its longitudinal extent. The latch is expediently held in the base body with carrier lugs so that it cannot be lost and, moreover, clear functional positions are always guaranteed. Finally, the invention recommends that the latch is convexly curved towards the approaches of the guide rail, so that the overall construction does not become too heavy. Since catching devices are often used even under harsh operating conditions, for example with dirt, the latch should at least partially be provided with locking marks on its surfaces that come into contact with the base body, which cause a certain self-cleaning effect in the course of the latch movement.

Auch der Grundkörper mit den Führungselementen sollte bezogen auf eine zu seiner Längserstreckung parallele Vertikalebene und Horizontalebene symmetrisch ausgebildet sein. Eine wei­ tere Erhöhung der Funktionstüchtigkeit ergibt sich aus der bevorzugten Ausführungsform, bei der der Schwerpunkt des Grundkörpers außerhalb der Führungsschiene liegt. Die inneren und äußeren Führungselemente können praktisch beliebig aus­gebildet sein. Sie können beispielsweise aus Paaren von Bo­genansätzen, insbesondere aber aus Rollen bestehen; selbst­verständlich sind auch Kombinationen von Bogenansätzen und Rollen möglich. Jedenfalls empfiehlt es sich, die äußeren Führungselemente in Langlöchern des Grundkörpers verschiebbar zu lagern und durch eine Feder in Richtung auf die Führungs­schiene zu beaufschlagen; es versteht sich von selbst, daß die Kraft dieser Feder so abzustimmen ist, daß die beschrie­benen Funktionen ohne weiteres ermöglicht werden.The base body with the guide elements should also be symmetrical in relation to a vertical plane and horizontal plane parallel to its longitudinal extent. A white Further increase in functionality results from the preferred embodiment in which the center of gravity of the base body lies outside the guide rail. The inner and outer guide elements can be practically arbitrary. You can, for example, consist of pairs of arch approaches, but in particular from roles; Of course, combinations of arch approaches and roles are also possible. In any case, it is recommended that the outer guide elements be slidably mounted in elongated holes in the base body and acted upon by a spring in the direction of the guide rail; it goes without saying that the force of this spring must be adjusted so that the functions described are readily possible.

Die in den Figuren dargestellte Fangeinrichtung 1 gehört zu einer Steigschutzeinrichtung mit einer Vertikal angeordneten Führungsschiene 2 und ist als sogenannter Innenläufer ausge­führt, d. h. die Führungsschiene 2 besteht aus einem mit ei­nem Längsschlitz 3 versehenen Kastenprofil, in welchem die Fangeinrichtung 1 läuft. Diese Fangeinrichtung 1 besteht in ihrem grundsätzlichen Aufbau aus einem Grundkörper 4, der an seinem gegenüber der Führungsschiene 2 vorkragenden Außenende einen Anschlag 5 für eine Zwischenverbindung zum Anschluß ei­nes Auffanggurtes und im Bereich seines anderen Endes 6, d. h. des Innenendes den Grundkörper 4 an der Führungsschiene 2 haltende innere und äußere Führungselemente 7 bzw. 8 auf­weist. Der Grundkörper 4 ist um eine zu seiner horizontalen Längserstreckung senkrechte Horizontalachse aus einer Bewe­gungsstellung, in der mit den Führungselementen 7, 8 längs der Führungsschiene 2 bewegbar ist, in eine Sperrstellung verschwenkbar ist, in der er mit einer Verriegelungsnase 9 an einem von mehreren gereihten Ansätzen 10 der Führungs­schiene 2 abstützbar ist. Die Bewegungsstellung ist in den Figuren dargestellt. Die Sperrstellung ergibt sich durch eine Verschwenkung im Uhrzeigersinn in Fig. 1.The safety device 1 shown in the figures belongs to a climbing protection device with a vertically arranged guide rail 2 and is designed as a so-called inner runner, ie the guide rail 2 consists of a box profile provided with a longitudinal slot 3, in which the safety device 1 runs. This catching device 1 consists of their basic structure of a base body 4, which has at its outer end projecting relative to the guide rail 2 a stop 5 for an intermediate connection for connecting a safety harness and in the area of its other end 6, ie the inner end of the base body 4 on the guide rail 2 holding inner and outer guide elements 7 or 8. The base body 4 can be pivoted about a horizontal axis perpendicular to its horizontal longitudinal extent from a movement position, in which the guide elements 7, 8 can be moved along the guide rail 2, into a locking position, in which it has a locking lug 9 on one of several approaches 10 of the guide rail 2 can be supported. The position of movement is shown in the figures. The blocking position results from a pivoting clockwise in FIG. 1.

Wie man insbesondere aus der Fig. 1 erkennt, ist am anderen Ende 6 bzw. Innenende des Grundkörpers 4 ein Verriegelungs­nasenträger 11 bewegbar gelagert, der durch Schwerkraft selbsttätig in eine Funktionsstellung übergeht, in der die Verriegelungsnase 9 in Bewegungsstellung des Grundkörpers 4 unmittelbar vor den Ansätzen 10 der Führungsschiene 2 liegt. Das Übergehen des Verriegelungsnasenträgers 11 in die Funk­tionsstellung ist in Fig. 1 schematisch angedeutet. Der Ver­riegelungsnasenträger 11 ist als Riegel ausgeführt, der in einer am Innenende des Grundkörpers 4 vorgesehenen Vertikal­ausnehmung 12 frei verschiebbar gelagert ist und an seinen beiden Enden mit jeweils einer Verriegelungsnase 9 versehen ist. Der Riegel weist praktisch quadratischen Querschnitt auf und ist bezogen auf einer zu seiner Längserstreckung senk­rechten Ebene symmetrisch ausgebildet. In Fig. 1 erkennt man auch Trägeransätze 13, mit denen der Riegel im Grundkörper 4 gehalten ist. Zu den Ansätzen 10 der Führungsschiene 2 hin ist der Riegel konvex gekrümmt. In Fig. 1 erkennt man weiter­hin, daß der Riegel an seinem mit dem Grundkörper 4 in Be­rührung kommenden Flächen zumindest teilweise mit Rastmarken 14 versehen ist.As can be seen in particular from FIG. 1, at the other end 6 or inner end of the base body 4, a locking lug carrier 11 is movably mounted, which by gravity automatically changes into a functional position in which the locking lug 9 in the moving position of the base body 4 immediately before the approaches 10 of the guide rail 2 lies. The transition of the locking nose carrier 11 into the functional position is indicated schematically in FIG. 1. The locking nose carrier 11 is designed as a bolt, which is mounted in a vertical recess 12 provided at the inner end of the base body 4 and can be freely displaced thereon Both ends are each provided with a locking lug 9. The bolt has a practically square cross section and is symmetrical in relation to a plane perpendicular to its longitudinal extent. In Fig. 1 you can also see carrier lugs 13 with which the bolt is held in the base body 4. The latch is convexly curved towards the lugs 10 of the guide rail 2. In Fig. 1 it can also be seen that the bolt is at least partially provided with locking marks 14 on its surfaces in contact with the base body 4.

Durch eine vergleichende Betrachtung der Fig. 1 und 2 verifi­ziert man leicht, daß der Grundkörper 4 mit den Führungsele­menten 7, 8 bezogen auf eine zu seiner Längsrichtung paral­lele Vertikalebene 15 und Horizontalebene 16 symmetrisch aus­gebildet ist. Dabei liegt der Schwerpunkt 17 des Grundkör­pers 4 außerhalb der Führungsschiene 2. Die inneren Führungs­elemente 7 bestehen aus einem Paar von Rollen. Die äußeren Führungselemente 8 bestehen aus zwei übereinander angeord­neten Paaren von Rollen, deren Achsen in Langlöchern 18 des Grundkörpers 4 verschiebbar gelagert sind und durch eine Fe­der 19 in Richtung auf die Führungsschiene 2 beaufschlagt sind.1 and 2, it is easily verified that the base body 4 with the guide elements 7, 8 is symmetrical with respect to a vertical plane 15 and a horizontal plane 16 parallel to its longitudinal direction. The center of gravity 17 of the base body 4 lies outside the guide rail 2. The inner guide elements 7 consist of a pair of rollers. The outer guide elements 8 consist of two pairs of rollers arranged one above the other, the axes of which are displaceably mounted in elongated holes 18 of the base body 4 and are acted upon by a spring 19 in the direction of the guide rail 2.
