Description

Kette aus Rundstahlgliedem Chain made of round steel links

Technisches GebietTechnical field

Die Erfindung betrifft eine Kette, insbesondere Hebezeugkette, aus ovalen Rundstahlgliedem, von denen mindestens einige mit Kennzeichnungen versehen sind.The invention relates to a chain, in particular hoist chain, made of oval round steel links, at least some of which are provided with markings.

Stand der TechnikState of the art

Es ist bei Ketten der vorstehenden Art allgemein üblich, Kennzeichnungen wie beispielsweise PrüfStempel, Produktionsjahrangaben, Losnummern und/oder Herstellernamen in die Längsschenkel von Kettengliedern einzuprägen. Diese Handhabungsweise bringt bei Ketten mit kleinen Gliedabmessungen, d.h. insbesondere bei Ketten für Kleinhebezeuge, sowohl aus Platzgründen als auch wegen der runden Kontur der Längsschenkel der Glieder gewisse Probleme mit sich, und dies ganz ab- gesehen davon, daß die Prägewerkzeuge aus Verschleißgründen vergleichsweise häufig erneuert werden müssen.In the case of chains of the above type, it is common practice to emboss markings such as test stamps, year of manufacture, lot numbers and / or manufacturer names in the longitudinal legs of chain links. This way of handling brings with chains with small link dimensions, i.e. Especially with chains for small hoists, both for reasons of space and because of the round contour of the longitudinal limbs of the links, there are certain problems, and quite apart from the fact that the embossing tools have to be replaced comparatively frequently for reasons of wear.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Kette der m Betracht gezogenen Gattung zu schaffen, die auf einfachere und wirtschaftlichere Art und Weise mit Kennzeichnungen versehen werden kann. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Anbringung der Kennzeichnungen Kennzeichnungsträger dienen, die als zwischen den Längsschenkeln der Rundstahlglieder angeordnete, den lichten Innenraum dieser Glieder überbrückende KunststoffStege ausgebildet sind.The invention has for its object to provide a chain of the genre considered, which can be provided with labels in a simpler and more economical manner. This object is achieved in that for the purpose of attaching the markings are used identification carriers which are designed as plastic webs arranged between the longitudinal legs of the round steel members and bridging the clear interior of these members.

Die erfindungsgemäße Kette bietet den Vorteil, daß der für die Anbringung von Kennzeichnungen zur Verfügung stehende Raum auch bei Ketten aus Gliedern mit kleinen Abmessungen vergleichsweise groß ist. Kurze Beschreibung der ZeichnungenThe chain according to the invention has the advantage that the space available for the attachment of markings is comparatively large even with chains made of links with small dimensions.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

In den Figuren 1 und 2 ist 1 ein erster Kennzeichnungsträger, der zwischen die Längsschenkel 2 und 3 eines ovalen Rundstahlglieds 4 eingeklemmt ist. Er besteht aus einem elasti- sehen Kunststoff, der sich mit Hilfe einer geeigneten Einpreßvorrichtung in die dargestellte Lage überführen läßt und eine Gewähr für einen sicheren Sitz bietet. Wie man aus Fig. 2 erkennt, umfassen die den Längsschenkeln 2, 3 zugewandten Enden des Kennzeichnungsträgers 1 die Innenflächen der Längs- Schenkel 2, 3 sichelförmig, d.h. formschlüssig, wobei die Stärke s des Kennzeichnungsträgers 1 gleich der Nenndicke d des Rundstahlglieds 4 ist. Die sich gegenüberliegenden Enden 5, β des Kennzeichnungsträgers sind breiter als sein Mittelteil 7, das Mulden 8, 9 für die Buge zweier in das Ketten- glied 4 eingehängter Kettenglieder 10 und 11 bildet.In Figures 1 and 2, 1 is a first identification carrier, which is clamped between the longitudinal legs 2 and 3 of an oval round steel member 4. It consists of an elastic plastic, which can be transferred into the position shown with the aid of a suitable press-in device and which guarantees a secure fit. As can be seen from Fig. 2, the ends of the label carrier 1 facing the longitudinal legs 2, 3 embrace the inner surfaces of the longitudinal legs 2, 3 in a crescent shape, i.e. form-fitting, the thickness s of the identification carrier 1 being equal to the nominal thickness d of the round steel member 4. The opposite ends 5, β of the identification carrier are wider than its central part 7, which forms troughs 8, 9 for the bend of two chain links 10 and 11 suspended in the chain link 4.

Bei dem Ausführungsbeispiel gemäß Fig. 3 und 4 ist das Rundstahlglied 4 mit einem Kennzeichnungsträger 12 ausgestattet, der von einem geraden Kunststoffsteg mit einer zentralen Kerbe 13 gebildet wird. Die Kerbe 13 erlaubt es, den Kennzeichnungsträger 12 bei der Montage V-förmig zu verfor- men, so daß sich die Verwendung einer Einpreßvorrichtung erübrigt .3 and 4, the round steel member 4 is equipped with an identification carrier 12, which is formed by a straight plastic web with a central notch 13. The notch 13 allows the To deform label carrier 12 in a V-shape during assembly, so that the use of a press-in device is unnecessary.

Eine besonders vorteilhafte Ausführungsform ist in den Figu- ren 5 bis 9 dargestellt. Sie zeigen einen Kennzeichnungsträger 14, der aus zwei Teilen 15 und 16 besteht, die durch eine Rastverbindung miteinander so verbunden sind, daß sie sich ohne Beschädigung der Teile 15, 16 nicht wieder voneinander trennen lassen. Die Teile 15 und 16 sind zu diesem Zweck mit hakenförmigen VorSprüngen 17 und diesen Vorsprüngen 17 zugeordneten Rastnuten 18 versehen. A particularly advantageous embodiment is shown in FIGS. 5 to 9. They show a label carrier 14, which consists of two parts 15 and 16, which are connected to one another by a snap connection so that they cannot be separated from one another again without damaging the parts 15, 16. For this purpose, the parts 15 and 16 are provided with hook-shaped projections 17 and locking grooves 18 assigned to these projections 17.
