Definitions

  • the present disclosure relates to corner protection rails according to DIN EN 14353 for a wall or ceiling edge formed with a plasterboard and / or plaster compound in a room or building.
  • corner protection rails are used in buildings as auxiliary profiles for the formation of wall or ceiling edges using plasterboard, joint filler and / or plastering compound.
  • Such corner protection rails are typically formed from thin sheet metal and, depending on the material and type, can be installed with or without a surface finish, or they can be filled into the wall or ceiling edge with joint filler material ready for painting or wallpapering.
  • the EP 2 316 611 B1 describes, for example, such a corner protection rail.

  • corner protection rails are often used, particularly in larger buildings.
  • a large part of the corner protection rails is initially longer than the wall or ceiling edge to be formed and must be shortened to a suitable length before installation. This is usually done by manually applying a length ruler, typically a 2 m folding rule, the zero point of which is placed on one end of the corner protection rail, and marking a desired length position at which the corner protection rail is to be shortened. If the nominal length exceeds the length scale, an intermediate marking must be set and the length scale must be pushed further to the intermediate marking before the nominal length position is marked can be. With a large number of corner protection rails to be processed, this costs a lot of working time. In addition, the dimensions are not always exact by applying a linear rule, since the zero point can slip and is not exactly on a front end or on an intermediate marking.
  • the corner protection rail disclosed herein allows the corner protection rails to be shortened much faster and more reliably.
  • the first and / or second length markings form a first length scale that starts from a zero point at the first front end.
  • the corner protection rail also has a length scale that corresponds to the first length scale second length scaling with first and second length markings, which starts from a zero point at the second front end.
  • the length of the corner protection rail is not a multiple of the second length markings of the second length scale, and the first and second length markings of the first length scale are not the same as the first and second length markings of the second length scale.
  • the corner protection rail according to the invention has the advantage that with a standard length of the corner protection rail that is not a multiple of the second length markings, the person processing the corner protection rail has the option of simply shortening the corner protection rail in length with respect to both ends. As a result, the corner protection rail does not have to be laboriously rotated about an axis running transversely to the longitudinal axis. In addition, after shortening the corner protection rail starting from one front end, the resulting waste can be shortened again starting from the other front end without applying an external length scale.
  • the corner protection rail described can furthermore be shortened very quickly due to the special arrangement of the first and second length markings with respect to one another without having to apply a length scale, since the first length markings allow fine length scaling and the second length markings allow coarser length scaling.
  • the first distance can be 1 mm and the second distance 5 mm.
  • every nth, for example fifth, of the first length markings can be formed by one of the second length markings.
  • every mth, for example second, of the second length markings can be formed by one of the third length markings.
  • Fourth or fifth can also be used analogously and / or further length markings with a respective spacing of for example 5 cm, 10 cm and / or 100 cm can be provided.
  • the length markings can form a length scale, typically known from a commercially available folding rule, which extends over the entire length of the corner protection rail. The the corner protection rail The processing person can then very quickly and reliably shorten the corner protection rail to the desired length.
  • the first and second length markings can be formed as cutouts from the first web and / or second web, which serve to anchor the corner protection rail to the wall or ceiling edge by means of plastering compound.
  • the punchings can be oriented in a polygonal manner in such a way that they point with an arrow-like corner to an outer edge of the respective web from which they are punched.
  • the polygonal shapes and / or sizes of the cutouts of the first length markings can easily differ from the polygonal shapes and / or sizes of the cutouts of the second length markings.
  • the cutouts of the first length markings can be small triangles and the cutouts of the first length markings can be larger pentagons or rhombuses.
  • curved shapes with an arrow-like corner such as a teardrop shape, can serve as punching out of the first and / or second length markings.
  • a first of the first length markings and a first of the second length markings can be formed by the first front end.
  • the first of the first length markings and a first of the second length markings preferably represent the zero point of a length scale. Such a zero point is particularly useful at a front end so that the corner protection rail only has to be shortened once.
  • the second length scaling can be arranged on a first side of the second web.
  • four sides of the corner protection rail are available for the length scaling: the first side of the first bar, the second side of the first bar, the first side of the second bar and the second side of the second bar.
  • the first sides can, for example, each be the inner sides of the corner protection rail, which in the installed state point towards the wall or ceiling and bear against it.

  • the first length scale can also be arranged on a second side of the second web and the second length scale can also be arranged on a second side of the first web. Then the shortening person no longer needs to turn the corner protection rail, since in practice either the first or the second sides of the webs are always visible.

  • the first, second and / or third length markings can be arranged on an outer edge of the first web and / or the second web.

  • This can be decided with optimized process costs in order to be able to offer the corner protection rail as cost-effectively as possible. Since corner protection rails known from the prior art already have punchings through which joint filler or plastering compound previously applied swells when the corner protection rail is pressed against the wall or ceiling edge to be formed and the corner protection rail is held in position, the length markings can be used in one process Punched out or embossed.

  • an embossing roller with a diameter of almost one meter was required, which cannot be easily integrated into the continuous production process.
  • the length markings can be rolled on or punched out over the entire length. Applying the length markings by means of printing and / or laser engraving can be particularly useful with lettering before or after the corner protection rails are cut to the standard length, although the length markings themselves can also be rolled in in an endless process without lettering, so that only the lettering is printed and / or laser engraved must be applied.
  • the first, second and / or third length markings can be machine-readable and / or machine-countable, so that a shortening device can determine a target position for shortening the corner protection rail by scanning the first, second and / or third length markings. There is then no need for human-readable labeling, which shortens the period length ⁇ and simplifies the application of the machine-readable length markings.
  • the shortening device can have a shortening unit which can move along the corner protection rail, can determine its position along the corner protection rail by machine counting and / or recognition of the length markings and can shorten the corner protection rail at the target position.

  • Target lengths that are below the distance between the coarsest length markings are preferably shortened manually, it being advantageous if the length markings are readable both by the user and by machine.

Description

Die vorliegende Offenbarung betrifft Eckschutzschienen nach DIN EN 14353 für eine mit einer Gipsplatte und/oder Verputzmasse gebildete Wand- oder Deckenkante in einem Raum oder Gebäude.The present disclosure relates to corner protection rails according to DIN EN 14353 for a wall or ceiling edge formed with a plasterboard and / or plaster compound in a room or building.

Bekannte Eckschutzschienen finden als Hilfsprofile zur Bildung von Wand- oder Deckenkanten mittels Gipsplatten, Fugenspachtel und/oder Verputzmasse Verwendung in Gebäuden. Solche Eckschutzschienen sind typischerweise aus dünnem Metallblech gebildet und können, abhängig von Material und Typ, sowohl mit als auch ohne Oberflächenendbehandlung eingebaut werden oder mit Fugenspachtel-Material fertig zum Streichen oder Tapezieren in die Wand- oder Deckenkante eingespachtelt werden. Die EP 2 316 611 B1 beschreibt beispielsweise eine solche Eckschutzschiene. In JPH0713955U oder JP 2013-199778 A ist ebenfalls eine Eckschutzschiene dieser Art beschrieben.Known corner protection rails are used in buildings as auxiliary profiles for the formation of wall or ceiling edges using plasterboard, joint filler and / or plastering compound. Such corner protection rails are typically formed from thin sheet metal and, depending on the material and type, can be installed with or without a surface finish, or they can be filled into the wall or ceiling edge with joint filler material ready for painting or wallpapering. The EP 2 316 611 B1 describes, for example, such a corner protection rail. In JPH0713955U or JP 2013-199778 A a corner protection rail of this type is also described.

Insbesondere bei größeren Gebäuden werden oft große Mengen von Eckschutzschienen verbaut. Ein Großteil der Eckschutzschienen ist dabei zunächst länger als die zu bildende Wand- oder Deckenkante und muss entsprechend vor dem Einbau auf eine passende Länge gekürzt werden. Dies geschieht üblicherweise durch manuelles Anlegen eines Längenmaßstabs, typischerweise eines 2m-Zollstocks, dessen Nullpunkt an ein Stirnende der Eckschutzschiene gelegt wird, und Markieren einer Solllängenposition, an der die Eckschutzschiene gekürzt werden soll. Übersteigt die Solllänge den Längenmaßstab, muss eine Zwischenmarkierung gesetzt und der Längenmaßstab zur Zwischenmarkierung weitergeschoben werden, bevor die Solllängenposition markiert werden kann. Dies kostet bei einer großen Anzahl an zu verarbeitenden Eckschutzschienen viel Arbeitszeit. Außerdem ist die Abmessung durch Anlegen eines Längenmaßstabs nicht immer genau, da der Nullpunkt verrutschen kann und nicht genau an einem Stirnende oder auf einer Zwischenmarkierung liegt.Large quantities of corner protection rails are often used, particularly in larger buildings. A large part of the corner protection rails is initially longer than the wall or ceiling edge to be formed and must be shortened to a suitable length before installation. This is usually done by manually applying a length ruler, typically a 2 m folding rule, the zero point of which is placed on one end of the corner protection rail, and marking a desired length position at which the corner protection rail is to be shortened. If the nominal length exceeds the length scale, an intermediate marking must be set and the length scale must be pushed further to the intermediate marking before the nominal length position is marked can be. With a large number of corner protection rails to be processed, this costs a lot of working time. In addition, the dimensions are not always exact by applying a linear rule, since the zero point can slip and is not exactly on a front end or on an intermediate marking.

Die hierin offenbarte Eckschutzschiene erlaubt ein weitaus schnelleres und verlässlicheres Kürzen der Eckschutzschienen.The corner protection rail disclosed herein allows the corner protection rails to be shortened much faster and more reliably.

Erfindungsgemäß wird dazu eine Eckschutzschiene bereitgestellt für eine mit einer Gipsplatte und/oder Verputzmasse gebildete Wand- oder Deckenkante in einem Raum oder Gebäude, wobei sich die Eckschutzschiene mit mindestens einem ersten Steg und einem zum ersten Steg im Wesentlichen senkrecht verlaufenden zweiten Steg entlang einer Längsrichtung von einem ersten Stirnende über eine Länge zu einem zweiten Stirnende erstreckt, wobei die Eckschutzschiene entsprechend der Wand- oder Deckenkante in der Länge kürzbar ist, wobei die Eckschutzschiene zum definierten Kürzen der Eckschutzschiene ohne anzulegenden Längenmaßstab auf einer ersten Seite des ersten Stegs entlang der gesamten Länge der Eckschutzschiene eine Mehrzahl von ersten Längenmarkierungen und erkennbar von den ersten Längenmarkierungen zu unterscheidenden zweiten Längenmarkierungen aufweist, wobei die ersten Längenmarkierungen einen definierten ersten Abstand voneinander und die zweiten Längenmarkierungen einen definierten zweiten Abstand voneinander haben, wobei der zweite Abstand ein ganzzahliges Vielfaches n, beispielsweise n=10, des ersten Abstands ist, wobei jede n-te der ersten Längenmarkierungen den gleichen Abstand zum ersten Stirnende hat wie eine der zweiten Längenmarkierungen. Die ersten und/oder zweiten Längenmarkierungen bilden eine erste Längenskalierung, die von einem Nullpunkt an dem ersten Stirnende ausgeht. Die Eckschutzschiene weist ferner eine der ersten Längenskalierung entsprechende zweite Längenskalierung mit ersten und zweiten Längenmarkierungen auf, die von einem Nullpunkt an dem zweiten Stirnende ausgeht. Dabei ist die Länge der Eckschutzschiene kein Vielfaches der zweiten Längenmarkierungen der zweiten Längenskalierung, und die ersten und zweiten Längenmarkierungen der ersten Längenskalierung liegen nicht gleichauf mit den ersten und zweiten Längenmarkierungen der zweiten Längenskalierung.According to the invention, a corner protection rail is provided for a wall or ceiling edge formed with a plasterboard and / or plastering compound in a room or building, the corner protection rail having at least one first web and a second web running essentially perpendicular to the first web along a longitudinal direction of a first front end extends over a length to a second front end, wherein the corner protection rail can be shortened in length according to the wall or ceiling edge, the corner protection rail for defined shortening of the corner protection rail without applying a length scale on a first side of the first web along the entire length of the Corner protection rail has a plurality of first length markings and second length markings recognizable to be differentiated from the first length markings, the first length markings a defined first distance from one another and the second length markings a defined second one en distance from one another, the second distance being an integral multiple n, for example n = 10, of the first distance, each nth of the first length markings being the same distance from the first end as one of the second length markings. The first and / or second length markings form a first length scale that starts from a zero point at the first front end. The corner protection rail also has a length scale that corresponds to the first length scale second length scaling with first and second length markings, which starts from a zero point at the second front end. The length of the corner protection rail is not a multiple of the second length markings of the second length scale, and the first and second length markings of the first length scale are not the same as the first and second length markings of the second length scale.

Die erfindungsgemäße Eckschutzschiene hat den Vorteil, dass bei einer Normlänge der Eckschutzschiene, die kein Vielfaches der zweiten Längenmarkierungen ist, die die Eckschutzschiene verarbeitende Person die Möglichkeit hat, die Eckschutzschiene einfach in Ihrer Länge bezüglich beider Stirnenden zu kürzen. Dadurch muss die Eckschutzschiene nicht umständlich um eine zur Längsachse quer verlaufende Achse gedreht werden. Außerdem kann nach einem von einem Stirnende ausgehenden Kürzen der Eckschutzschiene der resultierende Verschnitt nochmals ohne Anlegen eines externen Längenmaßstabs vom anderen Stirnende ausgehend gekürzt werden.The corner protection rail according to the invention has the advantage that with a standard length of the corner protection rail that is not a multiple of the second length markings, the person processing the corner protection rail has the option of simply shortening the corner protection rail in length with respect to both ends. As a result, the corner protection rail does not have to be laboriously rotated about an axis running transversely to the longitudinal axis. In addition, after shortening the corner protection rail starting from one front end, the resulting waste can be shortened again starting from the other front end without applying an external length scale.

Die beschriebene Eckschutzschiene
kann ferner durch die besondere Anordnung der ersten und zweiten Längenmarkierungen zueinander ohne anzulegenden Längenmaßstab sehr schnell gekürzt werden, da die ersten Längenmarkierungen eine feine Längenskalierung und die zweiten Längenmarkierungen eine gröbere Längenskalierung ermöglicht. Beispielsweise kann der erste Abstand 1 mm betragen und der zweite Abstand 5 mm. Optional kann jede n-te, beispielsweise fünfte, der ersten Längenmarkierungen durch eine der zweiten Längenmarkierungen gebildet sein. Optional kann die Eckschutzschiene eine auf der ersten Seite des ersten Stegs entlang der gesamten Länge der Eckschutzschiene angeordneten Mehrzahl von erkennbar von den ersten und zweiten Längenmarkierungen zu unterscheidenden dritten Längenmarkierungen aufweisen, wobei die dritten Längenmarkierungen einen definierten dritten Abstand voneinander haben, wobei der dritte Abstand, beispielsweise 10 mm, ein ganzzahliges Vielfaches m, beispielsweise m=2, des zweiten Abstands ist, wobei jede m-te, d.h. zweite, der zweiten Längenmarkierungen den gleichen Abstand zum ersten Stirnende und/oder zum zweiten Stirnende hat wie eine der dritten Längenmarkierungen. Optional kann jede m-te, beispielsweise zweite, der zweiten Längenmarkierungen durch eine der dritten Längenmarkierungen gebildet sein. Es können analog auch vierte, fünfte und/oder weitere Längenmarkierungen mit einem jeweiligen Abstand von beispielsweise 5 cm, 10 cm und/oder 100 cm vorgesehen sein. Die Längenmarkierungen können eine typischerweise von einem handelsüblichen Zollstock bekannte Längenskalierung bilden, die sich über die gesamte Länge der Eckschutzschiene erstreckt. Die die Eckschutzschiene verarbeitende Person kann dann sehr schnell und zuverlässig die Eckschutzschiene auf die Solllänge kürzen.The corner protection rail described
can furthermore be shortened very quickly due to the special arrangement of the first and second length markings with respect to one another without having to apply a length scale, since the first length markings allow fine length scaling and the second length markings allow coarser length scaling. For example, the first distance can be 1 mm and the second distance 5 mm. Optionally, every nth, for example fifth, of the first length markings can be formed by one of the second length markings. Optionally, the corner protection rail can have a plurality of third length markings, which are arranged on the first side of the first web along the entire length of the corner protection rail and can be clearly distinguished from the first and second length markings, the third length markings being at a defined third distance from one another, the third distance for example 10 mm, an integer multiple m, for example m = 2, of the second distance, each mth, ie second, of the second length markings being the same distance from the first end and / or the second end as one of the third length markings. Optionally, every mth, for example second, of the second length markings can be formed by one of the third length markings. Fourth or fifth can also be used analogously and / or further length markings with a respective spacing of for example 5 cm, 10 cm and / or 100 cm can be provided. The length markings can form a length scale, typically known from a commercially available folding rule, which extends over the entire length of the corner protection rail. The the corner protection rail The processing person can then very quickly and reliably shorten the corner protection rail to the desired length.

Optional können die ersten und zweiten Längenmarkierungen als Ausstanzungen aus dem ersten Steg und/oder zweiten Steg ausgebildet sein, die zur Verankerung der Eckschutzschiene an der Wand- oder Deckenkante mittels Verputzmasse dienen. Die Ausstanzungen können dabei polygonförmig so ausgerichtet sein, dass sie mit einer Ecke pfeilartig auf eine Außenkante des jeweiligen Stegs zeigen, aus dem sie gestanzt sind. Die Polygonformen und/oder -größen der Ausstanzungen der ersten Längenmarkierungen können sich dabei leicht erkennbar von den Polygonformen und/oder -größen der Ausstanzungen der zweiten Längenmarkierungen unterscheiden. Beispielsweise können die Ausstanzungen der ersten Längenmarkierungen kleine Dreiecke sein und die Ausstanzungen der ersten Längenmarkierungen größere Fünfecke oder Rauten. Alternativ zu Polygonformen können auch gekrümmte Formen mit pfeilartiger Ecke, wie etwa eine Tropfenform, als Ausstanzung der ersten und/oder zweiten Längenmarkierungen dienen.Optionally, the first and second length markings can be formed as cutouts from the first web and / or second web, which serve to anchor the corner protection rail to the wall or ceiling edge by means of plastering compound. The punchings can be oriented in a polygonal manner in such a way that they point with an arrow-like corner to an outer edge of the respective web from which they are punched. The polygonal shapes and / or sizes of the cutouts of the first length markings can easily differ from the polygonal shapes and / or sizes of the cutouts of the second length markings. For example, the cutouts of the first length markings can be small triangles and the cutouts of the first length markings can be larger pentagons or rhombuses. As an alternative to polygonal shapes, curved shapes with an arrow-like corner, such as a teardrop shape, can serve as punching out of the first and / or second length markings.

Optional kann eine erste der ersten Längenmarkierungen sowie eine erste der zweiten Längenmarkierungen durch das erste Stirnende gebildet sein. Die erste der ersten Längenmarkierungen sowie eine erste der zweiten Längenmarkierungen stellen vorzugsweise den Nullpunkt einer Längenskalierung dar. An einem Stirnende ist solch ein Nullpunkt besonders sinnvoll, damit die Eckschutzschiene nur einmal gekürzt werden muss.Optionally, a first of the first length markings and a first of the second length markings can be formed by the first front end. The first of the first length markings and a first of the second length markings preferably represent the zero point of a length scale. Such a zero point is particularly useful at a front end so that the corner protection rail only has to be shortened once.

Optional kann die zweite Längenskalierung auf einer ersten Seite des zweiten Stegs angeordnet sein. Prinzipiell stehen für die Längenskalierungen vier Seiten der Eckschutzschiene zur Verfügung: die erste Seite des ersten Stegs, die zweite Seite des ersten Stegs, die erste Seite des zweiten Stegs und die zweite Seite des zweiten Stegs. Die ersten Seiten können beispielsweise jeweils die Innenseiten der Eckschutzschiene sein, die im eingebauten Zustand zur Wand bzw. Decke weisen und an dieser anliegen. Die zweiten Seiten können beispielsweise jeweils die Außenseiten der Eckschutzschiene sein, auf welche Fugenspachtel oder Verputzmasse aufgetragen wird, um die Wand- bzw. Deckenkante zu bilden. Wenn Eckschutzschiene gerade so liegt, dass die erste Seite des ersten Stegs für eine die Eckschutzschiene kürzende Person sichtbar ist, dann ist auch die erste Seite des zweiten Stegs für diese Person gerade sichtbar. Die kürzende Person hat also beide Längenskalierungen im Blick und kann kurzerhand ohne weitere Drehungen der Eckschutzschiene das besser geeignete Stirnende als Nullpunkt wählen und die Eckschutzschiene entsprechend wahlweise anhand der ersten oder zweiten Längenskalierung kürzen.Optionally, the second length scaling can be arranged on a first side of the second web. In principle, four sides of the corner protection rail are available for the length scaling: the first side of the first bar, the second side of the first bar, the first side of the second bar and the second side of the second bar. The first sides can, for example, each be the inner sides of the corner protection rail, which in the installed state point towards the wall or ceiling and bear against it. The second sides can be, for example, the outer sides of the corner protection rail, to which joint filler or plastering compound is applied in order to form the wall or ceiling edge. If the corner protection rail is just so that the first side of the first web is visible to a person shortening the corner protection rail, then the first side of the second web is also just visible to this person. The shortening person has both length scales in view and can quickly and easily choose the more suitable front end as the zero point and without further turning the corner protection rail Shorten the corner protection rail accordingly using the first or second length scaling.

Optional kann die erste Längenskalierung zusätzlich auf einer zweiten Seite des zweiten Stegs angeordnet sein und die zweite Längenskalierung zusätzlich auf einer zweiten Seite des ersten Stegs angeordnet sein. Dann braucht die kürzende Person die Eckschutzschiene gar nicht mehr zu drehen, da in der Praxis immer entweder die ersten oder die zweiten Seiten der Stege sichtbar sind.Optionally, the first length scale can also be arranged on a second side of the second web and the second length scale can also be arranged on a second side of the first web. Then the shortening person no longer needs to turn the corner protection rail, since in practice either the first or the second sides of the webs are always visible.

Optional kann eine Untermenge oder sämtliche der ersten, zweiten und/oder dritten Längenmarkierungen jeweils mit einer Beschriftung versehen sein, die zumindest einen Zahlenwert für den Abstand der jeweils beschrifteten Längenmarkierung zum ersten Stirnende oder zum zweiten Stirnende angibt. Damit brauchen nicht alle Längenmarkierungen abgezählt zu werden, sondern es kann ein Großteil der Länge direkt abgelesen werden und ggf. nur noch wenige Längenmarkierungen abgezählt werden. Beispielsweise kann jede zehnte der zweiten Längenmarkierungen, die jeweils einen zweiten Abstand von 0,5 cm untereinander haben, mit einem Zahlenwert gekennzeichnet sein, der einem Vielfachen von 5 entspricht, also einem Längenwert in cm. Durch Abzählen müssen dann nur noch die relativ kurzen Strecken zwischen den beschrifteten Längenmarkierungen ermittelt werden.Optionally, a subset or all of the first, second and / or third length markings can each be provided with an inscription which specifies at least one numerical value for the distance between the length marking and the first end or the second end. This means that not all length markings need to be counted, but a large part of the length can be read off directly and, if necessary, only a few length markings can be counted. For example, every tenth of the second length markings, which each have a second distance of 0.5 cm from one another, can be identified with a numerical value that corresponds to a multiple of 5, that is to say a length value in cm. Then only the relatively short distances between the labeled length markings have to be determined by counting.

Optional kann die Beschriftung einer von den ersten, zweiten und/oder dritten Längenmarkierungen gebildeten ersten Längenskalierung, die von einem Nullpunkt an dem ersten Stirnende ausgeht, anders herum ausgerichtet sein als die Beschriftung einer entsprechenden zweiten Längenskalierung, die von einem Nullpunkt an dem zweiten Stirnende ausgeht, sodass jeweils die Beschriftung derjenigen Längenskalierung für einen auf die Eckschutzschiene blickenden Benutzer von links nach rechts lesbar ist, welche von dem Stirnende ausgeht, das links vom Benutzer liegt. Der Benutzer sei hier die die Eckschutzschiene kürzende Person. Da es oft leichter für den Benutzer ist, die eigene Position bezüglich der Eckschutzschiene zu wechseln als die lange Eckschutzschiene um eine quer zur Längsachse verlaufende Achse zu drehen, ist es sinnvoll für den Benutzer, über eine quer vor ihm liegende Eckschutzschiene zu steigen und sich zur Eckschutzschiene hin umzudrehen. Sodann liegt das andere Stirnende der Eckschutzschiene vom Benutzer aus links. Die andere Längenskalierung, die vorzugsweise gegenüber der einen anders herum, also auf dem Kopf, ausgerichtet ist, ist dann für den Benutzer von links nach rechts lesbar mit einem Nullpunkt, der am linken Stirnende liegt.Optionally, the inscription of a first length scale formed by the first, second and / or third length markings, which starts from a zero point at the first end face, can be oriented the other way around than the inscription of a corresponding second length scale, which starts out from a zero point at the second end face so that the labeling of that length scale can be read from left to right by a user looking at the corner protection rail which starts from the front end that is to the left of the user. The user is the person who shortens the corner protection rail. Since it is often easier for the user to change his own position with respect to the corner protection rail than to rotate the long corner protection rail around an axis running transversely to the longitudinal axis, it makes sense for the user to climb over a corner protection rail lying transversely in front of him and to move towards the Turn over the corner protection rail. The other front end of the corner protection rail is then on the left of the user. The other length scaling, which is preferably oriented the other way around, i.e. on the head, is then for readable by the user from left to right with a zero point on the left front end.

Optional können die ersten, zweiten und/oder dritten Längenmarkierungen an einer Außenkante des ersten Stegs und/oder des zweiten Stegs angeordnet sein. Dies ist vorteilhaft, da ein Seitenschneider, eine Zange, eine Schere, eine Säge oder anderes Mittel zum Kürzen der Eckschutzschiene vorzugsweise zunächst an einer Außenkante angesetzt wird. Alternativ oder zusätzlich können die ersten, zweiten und/oder dritten Längenmarkierungen an einer Innenkante des ersten Stegs und/oder des zweiten Stegs angeordnet sein. Dies ist vorteilhaft, da die Innenkante die eigentliche Wand- bzw. Deckenkante bildet, die eine bestimmte Länge haben soll. Außerdem kann es notwendig sein, dass der Benutzer eine Gehrung an einem Stirnende einschneidet, um den Übergang über eine Ecke zu einer anderen Eckschutzschiene zu bilden, wobei die Länge an der Innenkante besonders relevant ist.Optionally, the first, second and / or third length markings can be arranged on an outer edge of the first web and / or the second web. This is advantageous since side cutters, pliers, scissors, a saw or other means for shortening the corner protection rail are preferably initially applied to an outer edge. Alternatively or additionally, the first, second and / or third length markings can be arranged on an inner edge of the first web and / or the second web. This is advantageous because the inner edge forms the actual wall or ceiling edge, which should have a certain length. In addition, it may be necessary for the user to cut a miter at a front end in order to form the transition over one corner to another corner protection rail, the length at the inner edge being particularly relevant.

Optional können die ersten, zweiten und/oder dritten Längenmarkierungen durch Stanzen, Drucken, Kleben, Prägen, Lasergravur und/oder Walzen aufgebracht sein. Dies kann prozesskostenoptimiert entschieden werden, um die Eckschutzschiene möglichst kostengünstig anbieten zu können. Da aus dem Stand der Technik bekannte Eckschutzschienen bereits Ausstanzungen aufweisen, durch die sich beim Anpressen der Eckschutzschiene an die zu bildende Wand- bzw. Deckenkante zuvor aufgetragener Fugenspachtel oder Verputzmasse quillt und die Eckschutzschiene in Position hält, können die Längenmarkierungen in einem Prozess gleich mit den Ausstanzungen ausgestanzt oder eingeprägt werden.Optionally, the first, second and / or third length markings can be applied by punching, printing, gluing, embossing, laser engraving and / or rolling. This can be decided with optimized process costs in order to be able to offer the corner protection rail as cost-effectively as possible. Since corner protection rails known from the prior art already have punchings through which joint filler or plastering compound previously applied swells when the corner protection rail is pressed against the wall or ceiling edge to be formed and the corner protection rail is held in position, the length markings can be used in one process Punched out or embossed.

Optional können die Eckschutzschiene in einem Endlosverfahren aus einem Metallblech zu einem L-Winkel-Profil geformt und auf eine Normlänge gekappt sein. Eine technische Herausforderung stellt dabei das Aufbringen der Längenmarkierungen für Eckschutzschienen dar. Die Längenmarkierungen können dabei mittels einer entsprechend profilierten Prägewalze während des Walzens der Eckschutzschiene einprägt werden. Die Winkelposition der Prägewalze kann dazu mechanisch und/oder signalgesteuert mit der Vorrichtung zum Abkappen der Eckschutzschienen auf Normlänge gekoppelt sein, sodass die Längenmarkierungen einen definierten Abstand zu mindestens einem der Stirnende haben.Optionally, the corner protection rail can be formed into an L-angle profile in an endless process from sheet metal and cut to a standard length. This poses a technical challenge the application of the length markings for corner protection rails. The length markings can be impressed by means of a correspondingly profiled embossing roller while the corner protection rail is being rolled. For this purpose, the angular position of the embossing roller can be mechanically and / or signal-controlled with the device for capping the corner protection rails to the standard length, so that the length markings have a defined distance from at least one of the front ends.

Die technische Herausforderung erhöht sich hierbei mit der Periodenlänge, mit der sich die Längenmarkierungen bzw. Beschriftungen periodisch über die Länge wiederholen. Für eine Periodenlänge λ kann eine Prägewalze mit einem Durchmesser D von mindestens D = λ/π genutzt werden. Insbesondere Beschriftungen mit Zahlenwerten können sich überhaupt nicht wiederholen, sodass dann die Periodenlänge λ der Normlänge der Eckschutzschienen entspricht, mit der sie hergestellt und ausgeliefert werden. Bei einer Normlänge von beispielsweise 10 ft, was einer Länge von 3,048 m entspricht, benötigte man eine Prägewalze von knapp einem Meter Durchmesser, welche nicht ohne Weiteres in das Endlosproduktionsverfahren zu integrieren ist. Alternativ dazu kann nach dem Abkappen der Eckschutzschienen auf Normlänge ein Aufwalzen oder flächiges Einstanzen der Längenmarkierungen über die gesamte Länge stattfinden. Ein Aufbringen der Längenmarkierungen mittels Drucken und/oder Lasergravur kann insbesondere mit Beschriftung vor oder nach dem Abkappen der Eckschutzschienen auf Normlänge sinnvoll sein, wobei die Längenmarkierungen selbst ohne Beschriftung allerdings auch im Endlosverfahren eingewalzt werden können, sodass nur die Beschriftungen durch Drucken und/oder Lasergravur aufgebracht werden müssen.The technical challenge increases with the length of the period with which the length markings or labels repeat themselves periodically over the length. An embossing roller with a diameter D of at least D = λ / π can be used for a period length λ. In particular, inscriptions with numerical values cannot be repeated at all, so that the period length λ then corresponds to the standard length of the corner protection rails with which they are manufactured and delivered. With a standard length of 10 ft, for example, which corresponds to a length of 3.048 m, an embossing roller with a diameter of almost one meter was required, which cannot be easily integrated into the continuous production process. As an alternative to this, after the corner protection rails have been cut off to the standard length, the length markings can be rolled on or punched out over the entire length. Applying the length markings by means of printing and / or laser engraving can be particularly useful with lettering before or after the corner protection rails are cut to the standard length, although the length markings themselves can also be rolled in in an endless process without lettering, so that only the lettering is printed and / or laser engraved must be applied.

Optional können die ersten, zweiten und/oder dritten Längenmarkierungen maschinenlesbar und/oder maschinenzählbar sein, sodass eine Kürzungsvorrichtung eine Sollposition zum Kürzen der Eckschutzschiene durch Scannen der ersten, zweiten und/oder dritten Längenmarkierungen bestimmen kann. Es bedarf dann keiner menschlich lesbaren Beschriftung, was die Periodenlänge λ verkürzt und das Aufbringen der maschinell lesbaren Längenmarkierungen vereinfacht. Beispielsweise kann die Kürzungsvorrichtung eine Kürzungseinheit aufweisen, welche die Eckschutzschiene entlang abfahren kann, ihre Position entlang der Eckschutzschiene durch maschinelles Abzählen und/oder Erkennen der Längenmarkierungen bestimmen kann und die Eckschutzschiene an der Sollposition kürzen kann.Optionally, the first, second and / or third length markings can be machine-readable and / or machine-countable, so that a shortening device can determine a target position for shortening the corner protection rail by scanning the first, second and / or third length markings. There is then no need for human-readable labeling, which shortens the period length λ and simplifies the application of the machine-readable length markings. For example, the shortening device can have a shortening unit which can move along the corner protection rail, can determine its position along the corner protection rail by machine counting and / or recognition of the length markings and can shorten the corner protection rail at the target position.

Die Kürzungseinheit kann sich dabei beispielsweise mit Rollkontakt an der Eckschutzschiene selbst fortbewegen oder an einem Rahmen der Kürzungsvorrichtung, der eine Auflage für eine definierte Positionierung der Eckschutzschiene bietet. Einer mit Ungenauigkeiten behafteten Längen- bzw. Abstandsmessung durch die Kürzungsvorrichtung bedarf es ausdrücklich nicht, sondern nur einer Positionsbestimmung einer Kürzungseinheit anhand der maschinell lesbaren Längenmarkierungen auf der Eckschutzschiene. Maschinell lesbare Längenmarkierungen könnten beispielsweise Ausstanzungen unterschiedlicher Form und/oder Position sein, wobei eine die Eckschutzschiene über die Länge abfahrende Kürzungseinheit abhängig von der Solllängenvorgabe durch den Benutzer die entsprechenden überfahrenen ersten und/oder zweiten und/oder dritten usw. Längenmarkierungen zählt und eindeutig und schnell die Sollposition findet, ohne dass es auf den genauen Startpunkt der Kürzungseinheit ankommt. Das Scannen kann beispielsweise über die Reflexion eines Lichtstrahls an einem Steg der Eckschutzschiene durchgeführt werden. Die unterschiedlichen Längenmarkierungen können dabei in einer zur Längsrichtung der Eckschutzschiene senkrechten Ebene versetzt zueinander angeordnet sein, sodass für die ersten, zweiten, dritten usw. Längenmarkierungen ein separater Streifen zum Scannen überfahren werden kann. In dem Fall müssen sich die Längenmarkierungen nicht einmal in ihrer Form unterscheiden, da ihre Bedeutung aus ihrer Position am Steg der Eckschutzschiene eindeutig festgelegt ist.The shortening unit can, for example, move with rolling contact on the corner protection rail itself or on a frame of the shortening device, which provides a support for a defined positioning of the corner protection rail. A length or distance measurement with inaccuracies by the shortening device is expressly not required, but only a position determination of a shortening unit based on the machine-readable length markings on the corner protection rail. Machine-readable length markings could, for example, be cut-outs of different shapes and / or positions, with a shortening unit that traverses the corner protection rail over the length and counts the corresponding first and / or second and / or third etc. length markings that are passed over, clearly and quickly, depending on the target length specified by the user finds the target position without the exact starting point of the reduction unit being important. The scanning can be carried out, for example, by reflecting a light beam on a web of the corner protection rail. The different length markings can be offset from one another in a plane perpendicular to the longitudinal direction of the corner protection rail, so that a separate strip can be passed over for scanning for the first, second, third etc. length markings. In that case you need to the length markings do not even differ in their shape, since their meaning is clearly determined from their position on the web of the corner protection rail.

Die Kürzungseinheit kann beispielsweise eine definierte Fahrtrichtung haben und bestimmungsgemäß an beliebiger Stelle zwischen einem Stirnende und einer in Fahrtrichtung nächsten der gröbsten Längenmarkierung an die Eckschutzschiene angesetzt werden. Die gröbsten Längenmarkierungen können beispielsweise einen Abstand von 50 cm oder 100 cm zueinander haben, sodass die nächste Längenmarkierung 50 cm oder 100 cm vom Stirnende entfernt liegt. Sobald die Kürzungseinheit diese nächste Längenmarkierung überfährt, ist Ihre Position auf der Eckschutzschiene eindeutig aus der Anzahl der überfahrenen Längenmarkierungen bestimmbar. Sollängen, die unterhalb des Abstands der gröbsten Längenmarkierungen liegen, werden vorzugsweise manuell gekürzt, wobei es dann vorteilhaft ist, wenn die Längenmarkierungen sowohl für den Benutzer als auch maschinell lesbar sind.The shortening unit can, for example, have a defined direction of travel and, as intended, can be attached to the corner protection rail at any point between a front end and the closest to the coarsest length marking in the direction of travel. The coarsest length markings can, for example, have a distance of 50 cm or 100 cm from one another, so that the next length mark is 50 cm or 100 cm from the front end. As soon as the shortening unit crosses this next length marking, your position on the corner protection rail can be clearly determined from the number of length markings crossed. Target lengths that are below the distance between the coarsest length markings are preferably shortened manually, it being advantageous if the length markings are readable both by the user and by machine.

Um möglichst schnell an die Sollposition zu kommen, kann die Geschwindigkeit, mit der die Kürzungseinheit die Eckschutzschiene entlang fährt, von den bisher überfahrenen Längenmarkierungen abhängig sein. Beispielsweise können die ersten Längenmarkierungen einen ersten Abstand von 5 mm untereinander, die zweiten Längenmarkierungen einen zweiten Abstand von 100 mm untereinander, und die dritten Längenmarkierungen ebenfalls den ersten Abstand von 5 mm untereinander haben, wobei die dritten Längenmarkierungen mittig versetzt zu den ersten Längenmarkierungen angeordnet sind. Der Kürzungseinheit wird beispielsweise durch eine Eingabeschnittstelle (z. B. Sprachsteuerung, Tasteneingabe, drahtlose Signalübertragung, o. Ä) eine Solllänge von 2,85 m eingegeben und innerhalb der ersten 100 mm vom ersten Stirnende angesetzt. Die Kürzungseinheit kann die ersten 28 der zweiten Längenmarkierungen schnell überfahren und dann langsamer zur nächsten der ersten Längenmarkierungen vorfahren, um dort die Eckschutzschiene zu kappen. Falls die feinste der Längenmarkierungen nicht genau genug ist, kann die Kürzungseinheit dazu ausgestaltet sein, die genaue Kürzungsposition innerhalb der Kürzungseinheit im Rahmen einer feineren Skalierung zu verschieben. Im obigen Beispiel könnte ein millimetergenaues Kürzen durch eine definierte interne Verschiebung der genauen Kürzungsposition innerhalb der Kürzungseinheit um bis zu 2,5 mm erreicht werden.In order to get to the target position as quickly as possible, the speed at which the shortening unit travels along the corner protection rail can depend on the length markings that have been crossed so far. For example, the first length markings can have a first distance of 5 mm from one another, the second length markings a second distance of 100 mm from one another, and the third length markings can also have the first distance of 5 mm from one another, the third length markings being arranged centrally offset to the first length markings . A target length of 2.85 m is entered into the shortening unit, for example, through an input interface (e.g. voice control, key input, wireless signal transmission, or the like) and set within the first 100 mm from the first front end. The shortening unit can quickly pass over the first 28 of the second length markings and then more slowly to the Move forward to the next of the first length markings in order to cut the corner protection rail there. If the finest of the length markings is not precise enough, the shortening unit can be designed to shift the exact shortening position within the shortening unit within the scope of a finer scale. In the example above, shortening with millimeter precision could be achieved by a defined internal shift of the exact shortening position within the shortening unit by up to 2.5 mm.

Die Offenbarung ist nachfolgend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 eine perspektivische Ansicht auf einen Teil eines ersten Ausführungsbeispiels einer hierin offenbarten, nicht erfindungsgemäßen Eckschutzschiene; und
  • Fig. 2 eine perspektivische Ansicht auf einen Teil eines zweiten Ausführungsbeispiels einer hierin offenbarten, nicht erfindungsgemäßen Eckschutzschiene.
The disclosure is explained in more detail below with reference to the exemplary embodiments shown in the drawings. Show it:
  • Fig. 1 a perspective view of part of a first embodiment of a herein disclosed, not inventive corner protection rail; and
  • Fig. 2 a perspective view of part of a second embodiment of a herein disclosed, not inventive corner protection rail.

Fig. 1 zeigt einen Endabschnitt einer Eckschutzschiene 1 für eine mit einer Gipsplatte und/oder Verputzmasse gebildete Wand- oder Deckenkante in einem Raum oder Gebäude. Die Eckschutzschiene 1 hat hier ein L-förmiges Profil mit einem ersten Steg 3 und einem zum ersten Steg 3 im Wesentlichen senkrecht verlaufenden zweiten Steg 5. Die Eckschutzschiene 1 erstreckt sich von einem ersten Stirnende 6 über eine Normlänge zu einem zweiten Stirnende (nicht gezeigt). Zur besseren Orientierung ist in den Figuren ein rechtshändiges Kartesisches Koordinatensystem gezeigt, bei dem die z-Richtung entlang der Längsrichtung der Eckschutzschiene 1 verläuft, der erste Steg 3 sich in x-Richtung und der zweite Steg 5 sich in y-Richtung erstreckt. Die Stege 3, 5 sind an einer gemeinsamen Innenkante 7, die z-Richtung verläuft, miteinander als integrale Bestandteile der Eckschutzschiene 1 verbunden. Beide Stege 3, 5 weisen Ausstanzungen 9 auf, durch die Verputzmasse oder Fugenspachtel quillen und so die Eckschutzschiene 1 beim Anbringen an einer Wand- oder Deckenkante in Position halten kann. Die perspetivische Ansicht in Fig. 1 bietet einen Blick auf erste Innenseiten 11, 13 der Stege 3, 5, wobei die Innenseiten 11, 13 jeweils als erste Seiten der Stege 3, 5 bezeichnet werden können. Die Außenseiten, die man als zweite Seiten der Stege 3, 5 bezeichnen kann, sind in Fig. 1 nicht sichtbar. Fig. 1 shows an end section of a corner protection rail 1 for a wall or ceiling edge formed with a plasterboard and / or plastering compound in a room or building. The corner protection rail 1 here has an L-shaped profile with a first web 3 and a second web 5 that runs essentially perpendicular to the first web 3. The corner protection rail 1 extends from a first end 6 over a standard length to a second end (not shown). . For better orientation, the figures show a right-handed Cartesian coordinate system in which the z-direction runs along the longitudinal direction of the corner protection rail 1, the first web 3 extends in the x-direction and the second web 5 extends in the y-direction. The webs 3, 5 are connected to one another as integral components of the corner protection rail 1 at a common inner edge 7 running in the z direction. Both webs 3, 5 have cutouts 9 through the plastering compound or joint filler swell and so can hold the corner protection rail 1 in position when attached to a wall or ceiling edge. The perspective view in Fig. 1 offers a view of the first inner sides 11, 13 of the webs 3, 5, wherein the inner sides 11, 13 can each be referred to as the first sides of the webs 3, 5. The outer sides, which can be referred to as the second sides of the webs 3, 5, are in Fig. 1 not visible.

An einer ersten Außenkante 15 am ersten Steg 3 ist auf der Innenseite 11 eine erste Längenskalierung 17a mit ersten Längenmarkierungen 19a und zweiten Längenmarkierungen 21a erkennbar angeordnet. Die ersten Längenmarkierungen 19a haben einen definierten ersten Abstand A von 1 mm zueinander und sind durch kurze Striche und/oder Einkerbungen gebildet, die in x-Richtung verlaufen. Jede fünfte der ersten Längenmarkierungen 19a bildet dabei eine der zweiten Längenmarkierungen 21a, die einen definierten zweiten Abstand B von 5 mm untereinander haben und durch längere Striche und/oder Einkerbungen gebildet ist, die in x-Richtung verlaufen. Sowohl eine erste der ersten Längenmarkierungen 19a als auch eine erste der zweiten Längenmarkierungen 21a sind durch das erste Stirnende 6 selbst gebildet. An der dritten, siebten und elften der zweiten Längenmarkierungen 21a ist jeweils eine Beschriftung mit einem Zahlenwert "1", "3" bzw. "5" angeordnet, wobei der Zahlenwert dem Abstand der zughörigen zweiten Längenmarkierung 21a zum ersten Stirnende 6 in cm entspricht. Die Reihe der mit einem Zahlenwert beschrifteten zweiten Längenmarkierungen 21a kann so über die Länge bis zum zweiten Stirnende fortgeführt sein oder, beispielsweise falls eine Beschriftung in den Bereich einer der Ausstanzungen 9 fällt, vereinzelt ausgelassen sein.A first length scale 17a with first length markings 19a and second length markings 21a is recognizable on the inner side 11 on a first outer edge 15 on the first web 3. The first length markings 19a have a defined first distance A of 1 mm from one another and are formed by short lines and / or notches which run in the x direction. Every fifth of the first length markings 19a forms one of the second length markings 21a, which have a defined second distance B of 5 mm from one another and are formed by longer lines and / or notches which run in the x direction. Both a first of the first length markings 19a and a first of the second length markings 21a are formed by the first end face 6 itself. On the third, seventh and eleventh of the second length markings 21a there is an inscription with a numerical value "1", "3" or "5", the numerical value corresponding to the distance of the associated second length marking 21a to the first end 6 in cm. The row of the second length markings 21a labeled with a numerical value can thus be continued over the length to the second front end or, for example, if an inscription falls in the area of one of the cutouts 9, may be omitted in individual cases.

An einer zweiten Außenkante 23 am zweiten Steg 5 ist auf der Innenseite 13 eine zweite Längenskalierung 17b mit ersten Längenmarkierungen 19b und zweiten Längenmarkierungen 21b erkennbar angeordnet. Die ersten Längenmarkierungen 19b haben hier ebenfalls einen definierten ersten Abstand A von 1 mm zueinander und sind durch kurze Striche und/oder Einkerbungen gebildet, die in y-Richtung verlaufen. Jede fünfte der ersten Längenmarkierungen 19b bildet dabei eine der zweiten Längenmarkierungen 21b, die einen definierten zweiten Abstand B von 5 mm untereinander haben und durch längere Striche und/oder Einkerbungen gebildet ist, die in y-Richtung verlaufen. Sowohl eine erste der ersten Längenmarkierungen 19b als auch eine erste der zweiten Längenmarkierungen 21b sind durch das zweite Stirnende (nicht gezeigt) gebildet. An der 391., 395. und 399. der zweiten Längenmarkierungen 21b ist jeweils eine Beschriftung mit einem Zahlenwert angeordnet, wobei der Zahlenwert "195", "197" bzw. "199" dem Abstand der zughörigen zweiten Längenmarkierung 21b zum zweiten Stirnende (nicht gezeigt) in cm entspricht. Die Reihe der mit einem Zahlenwert beschrifteten zweiten Längenmarkierungen 21b kann so über die Länge vom zweiten Stirnende bis zum ersten Stirnende 6 fortgeführt sein oder, beispielsweise falls eine Beschriftung in den Bereich einer der Ausstanzungen 9 fällt, vereinzelt ausgelassen sein. Die Normlänge der hier gezeigten Eckschutzschiene 1 beträgt demnach ablesbar 200 cm. Da die Normlänge einem Vielfachen der zweiten Längenmarkierungen 21b entspricht, ist die letzte, also die 401., der zweiten Längenmarkierungen 21b durch das erste Stirnende 6 gebildet. Dies ist bei einer Normlänge, die erfindungsgemäß kein Vielfaches der zweiten Längenmarkierungen 21b ist, nicht der Fall. Beispielsweise bei einer Normlänge von 10 ft, also 3,048 m, wird die letzte der zweiten Längenmarkierungen 21b nicht durch das erste Stirnende 6 gebildet, sondern nur die erste der zweiten Längenmarkierungen 21b durch das zweite Stirnende (nicht gezeigt). Die Längenmarkierungen 19a, 21a der ersten Längenskalierung 17a liegen also erfindungsgemäß nicht, wie hier gezeigt, gleichauf mit den Längenmarkierungen 19b, 21b der zweiten Längenskalierung 17b.At a second outer edge 23 on the second web 5, a second length scale 17b with first length markings 19b and second length markings 21b is recognizable on the inner side 13. The first length markings 19b also have one here defined first distance A of 1 mm from one another and are formed by short lines and / or notches that run in the y-direction. Every fifth of the first length markings 19b forms one of the second length markings 21b, which have a defined second distance B of 5 mm from one another and are formed by longer lines and / or notches which run in the y direction. Both a first of the first length markings 19b and a first of the second length markings 21b are formed by the second end face (not shown). On the 391st, 395th and 399th of the second length markings 21b there is an inscription with a numerical value, the numerical value "195", "197" and "199" being the distance between the associated second length marking 21b and the second front end (not shown) in cm. The row of second length markings 21b labeled with a numerical value can thus be continued over the length from the second front end to the first front end 6 or, for example, if an inscription falls in the area of one of the punched-out portions 9, it can be omitted. The standard length of the corner protection rail 1 shown here is therefore 200 cm, which can be read off. Since the standard length corresponds to a multiple of the second length markings 21b, the last, ie the 401st, of the second length markings 21b is formed by the first end 6. This is not the case with a standard length which, according to the invention, is not a multiple of the second length markings 21b. For example, with a standard length of 10 ft, i.e. 3.048 m, the last of the second length markings 21b is not formed by the first end 6, but only the first of the second length markings 21b by the second end (not shown). According to the invention, the length markings 19a, 21a of the first length scale 17a are not, as shown here, the same as the length markings 19b, 21b of the second length scale 17b.

Die Beschriftungen der ersten Längenskalierung 17a auf dem ersten Steg 3 stehen für einen Benutzer mit einer der in Fig. 1 gezeigten Blickperspektive auf die Eckschutzschiene 1 auf dem Kopf. Die Beschriftungen der zweiten Längenskalierung 17b hingegen stehen für einen Benutzer mit einer der in Fig. 1 gezeigten Blickperspektive auf die Eckschutzschiene 1 von links nach rechts gut lesbar auf dem zweiten Steg 5. Die Blickperspektive entspricht hier in etwa einem Vektor (-1,-1) in der xy-Ebene. Der Nullpunkt der zweiten Längenskalierung 17b, der durch das zweite nicht gezeigte Stirnende gebildet wird, liegt dann links vom Benutzer, sodass der Benutzer bequem und schnell die Eckschutzschiene 1 auf eine relativ große Solllänge kürzen kann. Will der Benutzer die Eckschutzschiene 1 auf eine relativ kurze Solllänge kürzen, so kann er einfach und schnell die Eckschutzschiene um 90° gegen der Uhrzeigersinn um die z-Richtung drehen und seine eigene Position zur Eckschutzschiene 1 so verändern, dass seine Blickperspektive in etwa einem Vektor (-1,1) in der xy-Ebene entspricht. Dann liegt das erste Stirnende 6 links vom Benutzer, sodass der Benutzer bequem und schnell die Eckschutzschiene 1 auf eine relativ kleine Solllänge kürzen kann.The inscriptions of the first length scale 17a on the first web 3 represent a user with one of the in Fig. 1 Perspective shown on the corner protection rail 1 on the head. The inscriptions of the second length scale 17b, however, stand for a user with one of the in Fig. 1 The perspective shown on the corner protection rail 1 from left to right legible on the second web 5. The perspective here corresponds approximately to a vector (-1, -1) in the xy plane. The zero point of the second length scale 17b, which is formed by the second front end, not shown, is then to the left of the user, so that the user can conveniently and quickly shorten the corner protection rail 1 to a relatively large desired length. If the user wants to shorten the corner protection rail 1 to a relatively short nominal length, he can easily and quickly turn the corner protection rail by 90 ° counterclockwise around the z-direction and change his own position to the corner protection rail 1 so that his perspective is roughly a vector (-1,1) in the xy plane. The first front end 6 then lies to the left of the user, so that the user can conveniently and quickly shorten the corner protection rail 1 to a relatively small desired length.

Fig. 2 zeigt einen Teil eines zweiten Ausführungsbeispiels einer hierin offenbarten Eckschutzschiene 1. Im Unterschied zum ersten in Fig. 1 gezeigten Ausführungsbeispiel bilden hier die Ausstanzungen 9 erste Längenmarkierungen 19a, zweite Längenmarkierungen 21a und dritte Längenmarkierungen 25a einer ersten Längenskalierung 17a auf dem ersten Steg 3. Analog dazu bilden die Ausstanzungen 9 erste Längenmarkierungen 19b, zweite Längenmarkierungen 21b und dritte Längenmarkierungen 25b einer zweiten Längenskalierung 17b auf dem zweiten Steg 5. Fig. 2 shows part of a second exemplary embodiment of a corner protection rail 1 disclosed herein. In contrast to the first in FIG Fig. 1 The exemplary embodiment shown here form the cutouts 9 first length markings 19a, second length markings 21a and third length markings 25a of a first length scale 17a on the first web 3. Similarly, the cutouts 9 form first length markings 19b, second length markings 21b and third length markings 25b of a second length scale 17b the second bar 5.

Die ersten Längenmarkierungen 19a,b haben eine pfeilartige fünfeckige Form und liegen auf den jeweiligen Stegen 3, 5 näher an der gemeinsamen Innenkante 7 als die zweiten und dritten Längenmarkierungen 21a,b, 25a,b. Der erste Abstand A der ersten Längenmarkierungen 19a, 19b untereinander beträgt hier 5 mm. Die zweiten Längenmarkierungen 21a,b haben eine dreieckige kleinere Form und liegen auf den jeweiligen Stegen 3, 5 näher an der jeweiligen Außenkante 15, 23 als die ersten und dritten Längenmarkierungen 19a,b, 25a,b. Der zweite Abstand B der zweiten Längenmarkierungen 21a, 21b untereinander beträgt hier 100 mm. Hier wird nicht jede zehnte der ersten Längenmarkierungen 19a,b durch eine der zweiten Längenmarkierungen 21a, 21b gebildet, sondern jede zehnte der ersten Längenmarkierungen 19a,b hat lediglich den gleichen Abstand zu einem Stirnende (hier nicht gezeigt) wie eine der zweiten Längenmarkierungen 21a, 21b. Die dritten Längenmarkierungen 25a,b sind als Rauten ausgeführt und haben hier ebenfalls den ersten Abstand A von 5 mm zueinander, wobei die Rauten in z-Richtung mittig versetzt zu den ersten Längenmarkierungen 19a,b liegen. Jede dritte Längenmarkierung 25a,b hat also in z-Richtung gesehen den gleichen Abstand zu den zwei nächstgelegenen ersten Längenmarkierungen 19a,b, wobei dieser Abstand die Hälfte des ersten Abstands A von 5 mm, also 2,5 mm, beträgt. Die Rauten der dritten Längenmarkierungen 25a,b sind hier größer als die Dreiecke der zweiten Längenmarkierungen 21a,b und kleiner als die Fünfecke der ersten Längenmarkierungen 19a,b ausgeführt. In der x-Richtung gesehen liegen die dritten Längenmarkierungen 25a der ersten Längenskalierung 17a auf dem ersten Steg 3 zwischen den weiter innen angeordneten ersten Längenmarkierungen 19a und den weiter außen angeordneten zweiten Längenmarkierungen 21a. Analog liegen in der y-Richtung gesehen die dritten Längenmarkierungen 25b der zweiten Längenskalierung 17b auf dem zweiten Steg 5 zwischen den weiter innen angeordneten ersten Längenmarkierungen 19b und den weiter außen angeordneten zweiten Längenmarkierungen 21 b.The first length markings 19a, b have an arrow-like pentagonal shape and are located on the respective webs 3, 5 closer to the common inner edge 7 than the second and third length markings 21a, b, 25a, b. The first distance A between the first length markings 19a, 19b is 5 mm here. The second length marks 21a, b have a smaller triangular shape and lie on the respective webs 3, 5 closer to the respective outer edge 15, 23 than the first and third length markings 19a, b, 25a, b. The second distance B between the second length markings 21a, 21b is 100 mm here. Here, not every tenth of the first length markings 19a, b is formed by one of the second length markings 21a, 21b, but rather every tenth of the first length markings 19a, b has only the same distance from a front end (not shown here) as one of the second length markings 21a, 21b. The third length markings 25a, b are designed as diamonds and here also have the first distance A of 5 mm from one another, the diamonds being offset in the z-direction in the center of the first length markings 19a, b. Every third length marking 25a, b has the same distance, viewed in the z direction, from the two closest first length markings 19a, b, this distance being half of the first distance A of 5 mm, that is to say 2.5 mm. The diamonds of the third length markings 25a, b are larger than the triangles of the second length markings 21a, b and smaller than the pentagons of the first length markings 19a, b. As seen in the x-direction, the third length markings 25a of the first length scale 17a lie on the first web 3 between the first length markings 19a arranged further inside and the second length markings 21a arranged further out. Analogously, viewed in the y-direction, the third length markings 25b of the second length scale 17b lie on the second web 5 between the first length markings 19b arranged further inside and the second length markings 21b arranged further out.

Insbesondere das zweite in Fig. 2 gezeigte Ausführungsbeispiel eignet sich für eine maschinelle Auslese der Längenmarkierungen, da diese besonders einfach mittels Scannen maschinenlesbar und -zählbar sind. Durch die unterschiedliche Form und/oder Position an den jeweiligen Stegen kann eine Kürzungsvorrichtung mit einer über die Länge der Eckschutzschiene 1 verfahrbaren Kürzungseinheit eine Sollposition zum Kürzen der Eckschutzschiene 1 durch Scannen und Zählen der jeweiligen Längenmarkierungen bestimmen und anfahren, um diese dort zu kürzen.In particular, the second in Fig. 2 The embodiment shown is suitable for a machine reading of the length markings, since these can be machine-read and counted particularly easily by means of scanning. Due to the different shape and / or position on the respective A shortening device with a shortening unit that can be moved over the length of the corner protection rail 1 can determine and move to a target position for shortening the corner protection rail 1 by scanning and counting the respective length markings in order to shorten them there.
