BESCHREIBUNG DESCRIPTION

Die Erfindung betrifft einen für Geländer, Ziergitter und dergl. bestimmten metallischen Zierstab von im wesentlichen rechteckiger oder quadratischer Querschnittsgestalt, der im Bereiche seiner Längskanten hammerschlagähnliche, längliche Vertiefungen aufweist. The invention relates to a metallic decorative rod intended for railings, decorative grilles and the like, of essentially rectangular or square cross-sectional shape, which has elongated depressions similar to a hammer blow in the region of its longitudinal edges.

Solche Zierstäbe werden in der Praxis aus aus Schmiedeeisen bestehenden vollen Stäben geschmiedet. Sie sind deshalb verhältnismässig schwer, was bedeutet, dass aus solchen Zierstäben zusammengesetzte Treppengeländer, Ziergitter, Balkongitter, Möbelteile und dergl. schmiedeeiserne Einrichtungen ein hohes Gewicht aufweisen und einen entsprechend grossen Materialeinsatz erforderlich machen. Bei Toren bedeutet dies beispielsweise, dass die Angeln und deren Halterungen sowie die Pfeiler für die Tore entsprechend schwer ausgeführt werden müssen. In practice, such decorative bars are forged from full bars made of wrought iron. They are therefore relatively heavy, which means that stair rails, decorative grilles, balcony grilles, furniture parts and the like. Wrought-iron facilities composed of such decorative bars are heavy and require a correspondingly large amount of material. In the case of gates, this means, for example, that the hinges and their holders as well as the pillars for the gates must be made correspondingly heavy.

Aufgabe der Erfindung ist es, hier abzuhelfen und einen Zierstab zu schaffen, der sich von seinem Äusseren her kaum von dem gewohnten Erscheinungsbild eines geschmiedeten massiven Zierstabes unterscheidet, sich aber bei einfacher Herstellungsmöglichkeit durch ein wesentlich geringeres Gewicht auszeichnet. The object of the invention is to remedy this and to create a decorative rod which hardly differs from the outside from the usual appearance of a forged solid decorative rod, but is distinguished by a much lower weight with a simple production possibility.

Zur Lösung dieser Aufgabe ist der eingangs genannte Zierstab neuerungsgemäss dadurch gekennzeichnet, dass er in Gestalt eines Hohlprofilrohres ausgebildet ist, in dessen Wandung die Vertiefungen im Bereiche der Längskanten regelmässig verteilt eingewalzt sind. To solve this problem, the decorative rod mentioned at the outset is characterized in that it is designed in the form of a hollow profile tube, in the wall of which the depressions in the region of the longitudinal edges are rolled in in a regularly distributed manner.

Das im Querschnitt im wesentlichen rechteckige Hohlprofilrohr ist an den Längskanten im Bereiche der länglichen Vertiefungen plastisch verformt, wobei dadurch, dass die Vertiefungen eingewalzt sind, gewährleistet ist, dass die Seitenflächen des Hohlprofilrohres im wesentlichen ihre ebene Gestalt beibehalten, wie dies bei einem massiven geschmiedeten Zierstab auch der Fall ist. The hollow section tube, which is essentially rectangular in cross section, is plastically deformed on the longitudinal edges in the region of the elongated depressions, whereby the fact that the depressions are rolled in ensures that the side surfaces of the hollow section tube essentially retain their flat shape, as is the case with a solid forged decorative rod is also the case.

Der neue Zierstab zeichnet sich gegenüber den bekannten massiven Zierstäben durch ein wesentlich verringertes Gewicht aus, wobei die Biegesteifigkeit und die Knickfestig keit erhöht sind. The new decorative rod is characterized by a significantly reduced weight compared to the known solid decorative rods, whereby the bending stiffness and the resistance to buckling are increased.

Die an benachbarten Längskanten angeordneten Vertiefungen können in Stablängsrichtung gegeneinander versetzt sein, um eine möglichst gleichmässige Belastbarkeit des Zierstabes zu gewährleisten. Die Anordnung kann aber auch derart getroffen sein, dass an benachbarten Längskanten die Vertiefungen einander gegenüberliegend angeordnet sind. The depressions arranged on adjacent longitudinal edges can be offset with respect to one another in the longitudinal direction of the rod in order to ensure that the decorative rod can be loaded as uniformly as possible. However, the arrangement can also be such that the depressions are arranged opposite one another on adjacent longitudinal edges.

Die Vertiefungen können im Bereiche der Längskanten so tief eingewalzt sein, dass die Hohlprofilrohrwandung im Bereiche der Vertiefungen auf der Rohrinnenseite verformt ist. Damit ergibt sich ein besonders ausgeprägter hammerschlagähnlicher Effekt. Dadurch, dass die Vertiefungen eingewalzt sind, können sie mit geringer Mühe auch gleichgestaltet ausgebildet sein, womit der Zierstab ein besonders gleichmässiges Aussehen erhält. The depressions in the area of the longitudinal edges can be rolled so deep that the hollow profile tube wall is deformed in the area of the depressions on the inside of the tube. This results in a particularly pronounced hammer-like effect. Due to the fact that the depressions are rolled in, they can also be designed with the same effort with little effort, which gives the decorative rod a particularly uniform appearance.

Das Hohlprofilrohr des neuen Zierstabes besteht vorzugsweise aus einem weichen, kaltverformbaren Stahl oder Schmiedeeisen. Grundsätzlich sind aber auch Ausführungsformen denkbar, bei denen der Zierstab aus einem Leichtmetallhohlprofilrohr besteht, was eine weitere Gewichtsersparnis mit sich bringt. Wenn der Leichtmetallhohlprofilstab auf seiner Aussenseite entsprechend beschichtet oder gefärbt ist, ist er von einem handgeschmiedeten massiven Zierstab kaum zu unterscheiden. The hollow profile tube of the new decorative rod is preferably made of a soft, cold-formable steel or wrought iron. Basically, however, embodiments are also conceivable in which the decorative rod consists of a light metal hollow profile tube, which brings further weight savings. If the light metal hollow profile rod is coated or colored accordingly on the outside, it can hardly be distinguished from a hand-forged solid decorative rod.

In der Zeichnung sind zwei Ausführungsbeispiele des Gegenstandes der Erfindung dargestellt. Es zeigen: Fig. 1-2 jeweils einen Zierstab gemäss der Erfindung, mit unterschiedlicher Verteilung der hammerschlagähnlichen Vertiefungen, jeweils im Ausschnitt und in einer perspektivischen Darstellung. The drawing shows two exemplary embodiments of the subject matter of the invention. Show it: Fig. 1-2 each a decorative rod according to the invention, with different distribution of the hammer blow-like depressions, each in detail and in a perspective view.

Der für Geländer, Ziergitter, Möbelteile und dergleichen bestimmte Zierstab ist in Gestalt eines Hohlprofilrohres 1 ausgebildet, das eine im wesentlichen rechteckige oder quadratische Querschnittsgestalt aufweist und dessen Wandung im Bereich der Längskanten 2 aussen längliche, hammerschlagähnliche Vertiefungen 3 aufweist, die über die Stablängsrichtung regelmässig verteilt angeordnet und in das Hohlprofilrohrmaterial kalt eingewalzt sind. Die Vertiefungen 3, deren Umrissgestalt der Verschneidung zwischen einem Zylinder und der plastisch verformten Wandung des quadratischen oder rechteckigen Hohlprofilrohres 1 im Bereiche dessen Längskanten 2 entspricht, sind bei der Ausführungsform nach Fig. 1 an benachbarten Längskanten 2 in Stablängsrichtung gegeneinander versetzt. The decorative rod intended for railings, decorative grilles, furniture parts and the like is designed in the form of a hollow section tube 1 which has an essentially rectangular or square cross-sectional shape and the wall of which in the area of the longitudinal edges 2 has elongated, hammer-like depressions 3 on the outside, which are regularly distributed over the longitudinal direction of the rod arranged and cold rolled into the hollow section tube material. The depressions 3, the outline of which corresponds to the intersection between a cylinder and the plastically deformed wall of the square or rectangular hollow profile tube 1 in the region of its longitudinal edges 2, are offset in the embodiment according to FIG. 1 on adjacent longitudinal edges 2 in the longitudinal direction of the rod.

Bei der Ausführungsform nach Fig. 2 ist die Anordnung derart getroffen, dass an benachbarten Längskanten 2 die Vertiefungen 3 einander gegenüberliegend angeordnet sind, wie dies durch die gestrichelten Linien 4 angedeutet ist. In the embodiment according to FIG. 2, the arrangement is such that the depressions 3 are arranged opposite one another on adjacent longitudinal edges 2, as is indicated by the dashed lines 4.

Das Hohlprofilrohr 1 besteht aus kaltverformbarem Stahl oder aus einem ebenfalls kaltverformbaren Leichtmetall, beispielsweise Aluminium. Die Länge des Zierstabes ist den jeweiligen Erfordernissen angepasst. The hollow section tube 1 consists of cold-formable steel or of a likewise cold-formable light metal, for example aluminum. The length of the decorative rod is adapted to the respective requirements.

Die Vertiefungen 3 sind alle gleichgestaltet; sie weisen wie bereits erwähnt - gleiche Abstände in Stablängsrichtung auf. The depressions 3 are all of the same design; As already mentioned, they have the same distances in the longitudinal direction of the bar.

Die Wandstärke des Hohlprofilrohres und die Tiefe der kalt eingewalzten Vertiefungen 3 sind derart gewählt, dass sich bei der dargestellten Ausführungsform eine Verformung der Hohlprofillinnenwandung 5 im Bereiche der Vertiefungen 3 ergibt. Diese Verformungen auf der Rohrinnenseite sind bei 6 angedeutet. Sie sind ersichtlich auf den Bereich der Längskanten beschränkt, so dass die Seitenflächen 7 des Profilrohres 1 im wesentlichen ihre ebene Gestalt beibehalten. The wall thickness of the hollow profile tube and the depth of the cold-rolled depressions 3 are selected such that, in the embodiment shown, there is a deformation of the hollow profile inner wall 5 in the region of the depressions 3. These deformations on the inside of the tube are indicated at 6. They are clearly limited to the area of the longitudinal edges, so that the side surfaces 7 of the profile tube 1 essentially maintain their flat shape.

Unter Zierstab sind nicht nur gerade Stäbe vorbestimmter Länge, sondern auch andere stabartige Zierelemente verstanden, beispielsweise Gurte, Gestellteile, Geländer-Handläufe und dergleichen. Die Zierstäbe können als Meterware hergestellt und entsprechend abgelängt sein. Sie können auch gebogen sein. Decorative rod is not only understood to mean straight rods of a predetermined length, but also other rod-like decorative elements, for example belts, frame parts, handrail rails and the like. The decorative rods can be made by the meter and cut to length accordingly. They can also be curved.

DESCRIPTION

The invention relates to a metallic decorative rod intended for railings, decorative grilles and the like, of essentially rectangular or square cross-sectional shape, which has elongated depressions similar to a hammer blow in the region of its longitudinal edges.

In practice, such decorative bars are forged from full bars made of wrought iron. They are therefore relatively heavy, which means that stair rails, decorative grilles, balcony grilles, furniture parts and the like. Wrought-iron facilities composed of such decorative bars are heavy and require a correspondingly large amount of material. In the case of gates, this means, for example, that the hinges and their holders as well as the pillars for the gates must be made correspondingly heavy.

The object of the invention is to remedy this and to create a decorative rod which hardly differs from the outside from the usual appearance of a forged solid decorative rod, but is distinguished by a much lower weight with a simple production possibility.

To solve this problem, the decorative rod mentioned at the outset is characterized in that it is designed in the form of a hollow profile tube, in the wall of which the depressions in the region of the longitudinal edges are rolled in in a regularly distributed manner.

The hollow section tube, which is essentially rectangular in cross section, is plastically deformed on the longitudinal edges in the region of the elongated depressions, whereby the fact that the depressions are rolled in ensures that the side surfaces of the hollow section tube essentially retain their flat shape, as is the case with a solid forged decorative rod is also the case.

The new decorative rod is characterized by a significantly reduced weight compared to the known solid decorative rods, whereby the bending stiffness and the resistance to buckling are increased.

The depressions arranged on adjacent longitudinal edges can be offset with respect to one another in the longitudinal direction of the rod in order to ensure that the decorative rod can be loaded as uniformly as possible. However, the arrangement can also be such that the depressions are arranged opposite one another on adjacent longitudinal edges.

The depressions in the area of the longitudinal edges can be rolled so deep that the hollow profile tube wall is deformed in the area of the depressions on the inside of the tube. This results in a particularly pronounced hammer-like effect. Due to the fact that the depressions are rolled in, they can also be designed with the same effort with little effort, which gives the decorative rod a particularly uniform appearance.

The hollow profile tube of the new decorative rod is preferably made of a soft, cold-formable steel or wrought iron. Basically, however, embodiments are also conceivable in which the decorative rod consists of a light metal hollow profile tube, which brings further weight savings. If the light metal hollow profile rod is coated or colored accordingly on the outside, it can hardly be distinguished from a hand-forged solid decorative rod.

The drawing shows two exemplary embodiments of the subject matter of the invention. Show it: Fig. 1-2 each a decorative rod according to the invention, with different distribution of the hammer blow-like depressions, each in detail and in a perspective view.

The decorative rod intended for railings, decorative grilles, furniture parts and the like is designed in the form of a hollow section tube 1 which has an essentially rectangular or square cross-sectional shape and the wall of which in the area of the longitudinal edges 2 has elongated, hammer-like depressions 3 on the outside, which are regularly distributed over the longitudinal direction of the rod arranged and cold rolled into the hollow section tube material. The depressions 3, the outline of which corresponds to the intersection between a cylinder and the plastically deformed wall of the square or rectangular hollow profile tube 1 in the region of its longitudinal edges 2, are offset in the embodiment according to FIG. 1 on adjacent longitudinal edges 2 in the longitudinal direction of the rod.

In the embodiment according to FIG. 2, the arrangement is such that the depressions 3 are arranged opposite one another on adjacent longitudinal edges 2, as is indicated by the dashed lines 4.

The hollow section tube 1 consists of cold-formable steel or of a likewise cold-formable light metal, for example aluminum. The length of the decorative rod is adapted to the respective requirements.

The depressions 3 are all of the same design; As already mentioned, they have the same distances in the longitudinal direction of the bar.

The wall thickness of the hollow profile tube and the depth of the cold-rolled depressions 3 are selected such that, in the embodiment shown, there is a deformation of the hollow profile inner wall 5 in the region of the depressions 3. These deformations on the inside of the tube are indicated at 6. They are clearly limited to the area of the longitudinal edges, so that the side surfaces 7 of the profile tube 1 essentially maintain their flat shape.

Decorative rod is not only understood to mean straight rods of a predetermined length, but also other rod-like decorative elements, for example belts, frame parts, handrail rails and the like. The decorative rods can be made by the meter and cut to length accordingly. They can also be curved.
