Definitions
- the present invention relates to an extendable table comprising a table frame with usually four table legs, a base plate which defines a table top with an area of size A, and comprising at least one attachment plate which can be folded out by a pivoting movement and which, in the folded out state, increases the area of the table top by a certain amount x enlarged and the base plate lengthened in one direction.
- an extending table in which a base plate rests on a table frame with four table legs and when not extended the four table legs are each located in the corner areas below the base plate. If the area of the table top is to be increased, the table can be extended in a longitudinal direction in such a way that the table frame is extended, which increases the distance between the two table legs, which are located on the extended part of the frame, from the other two stationary table legs , so that when the table is extended, the table legs are again approximately in the corner areas of the extended table top.
- two swiveling attachment plates are provided which, when the table is not extended, are located below the level of the base plate and which can be folded by a swiveling movement about a horizontal axis of rotation extending in the longitudinal direction of the table, so that they can then be lie in the plane of the base plate and extend it in the longitudinal direction of the table.
- the two extension plates are approximately the same size and each extend transversely over about half the width of the table top, while both extension plates each extend longitudinally over the length by which the table top is lengthened. In the unfolded state, the two extension plates together form the extended surface of the table top, which adjoins the base plate in the longitudinal direction.
- the two attachment plates are connected to one another via hinges where they adjoin one another.
- This type of foldable extension table extension is also known as the "Butterfly" system.
- the two attachment plates When folded, the two attachment plates are positioned so that the underside is at the top. There is one on one of the attachment plates Grip tab or the like which the user can grasp to unfold the extension panels in a pivoting motion.
- the extension plates are usually only connected to the table frame at a few points. This can cause the sheet material to warp over time.
- the distortion is not only caused by the design, but is also increased by the influence of temperature and humidity. This effect occurs in particular when the extendable table is intended for outdoor use and is therefore exposed to the effects of the weather.
- the object of the present invention is to provide an extendable table in which the above-mentioned distortion of the attachment plates is avoided.
- the reinforcement bar is screwed to the attachment plate.
- the reinforcement bar is screwed to the attachment plate at several points using suitable screws that can be screwed into the wooden material of the reinforcement bar and the attachment plate. It may be advantageous to drill holes at least in the reinforcing strip in order to facilitate the screwing process.
- the reinforcement strip has a material thickness that corresponds at least to the material thickness of the attachment plate.
- the reinforcement bar should not be too thin.
- the reinforcement strip at least approximately doubles the original material thickness of the attachment plate.
- the reinforcement strip has a material thickness of at least approximately 10 mm, preferably a material thickness of at least approximately 15 mm.
- the thickness of the material also plays a role here the attachment plate itself plays a role.
- the reinforcement bar can then have a material thickness of 10 mm or more, particularly preferably 15 mm or more, for example between 15 mm and 20 mm, so that the material thickness of the attachment plate in the area of the reinforcement bars is doubled or more than doubled, which effective stabilization is sufficient.
- the reinforcement strip has at least one cutout that accommodates a folding hinge.
- the folding hinge or several such folding hinges are required in order to connect the attachment plate in an articulated manner to another attachment plate, in which case the two attachment plates can then be folded out in a pivoting movement about an axis of rotation from a quasi-sunken position into the position of use, in which they are in the plane of the Base plate lie and their surface - and thus the table top - increase in one direction by a defined amount.
- the folding hinge is then sunk or at least partially sunk in the reinforcement strip due to the milling.
- the reinforcing bar is used to attach a folding hinge, which allows the use of more stable fittings due to the increased material thickness.
- the attachment plate is designed in two parts and consists of two part plates connected to one another in an articulated manner, since with this structural solution the two attachment plates can be better accommodated in the table frame when not in use and handling when folding out the attachment plates is also easier. if these individually have a smaller size and thus a lower weight than when using only a single larger attachment plate.
- the attachment plate is connected at least at one point to an axis of rotation, which in turn is mounted on the table frame.
- the attachment plate By unfolding and pivoting about this axis of rotation, the attachment plate, or the entirety of the two attachment plates connected to one another, is then pivoted into the position of use.
- This type of construction of an extendable table with two pivotable, fold-out attachment plates is known per se from the prior art.
- the present invention is therefore about stabilizing the attachment plates with the help of one or more reinforcement strips, preferably made of HPL, as well as water-free glued wood materials or plywood.
- At least one folding hinge connects the interconnected partial panels to one another in an articulated manner.
- there are several such folding hinges which are approximately aligned at a distance from one another, preferably along or near an edge, in particular a longitudinal edge, at which the two partial plates of the attachment plate are connected to one another in an articulated manner.
- At least two reinforcement strips are attached to an attachment plate.
- two reinforcing strips are attached to an attachment plate at a distance from one another, preferably in an approximately parallel orientation to one another.
- one of these reinforcement strips can be attached more centrally under the attachment plate and the other more in the edge area, in particular in the vicinity of the edge via which the attachment plate is connected in an articulated manner to another sub-plate.
- At least one reinforcement bar extends in the longitudinal direction of the attachment plate and/or the reinforcement bar extends over more than half the length of the attachment plate, particularly preferably over most of the length of the attachment plate. Because the heel plate is typically rectangular, warpage is most likely to occur in the longitudinal direction, which has the larger dimension. It is therefore advisable to also align the reinforcement strips in the longitudinal direction of the attachment plate.
- the reinforcement strip does not have to extend over the entire length of the extension plate, but it is advantageous if the reinforcement strip is not too short in relation to the length of the extension plate, otherwise the desired effect of mechanical stabilization will not be achieved to a sufficient extent.
- one of the reinforcement strips has one or more cutouts, each of which accommodates a folding hinge.
- the cut-outs are only required when using a reinforcement strip which is located near the edge around which the attachment plate is pivotably connected to another sub-plate.
- figure 1 shows a view of the extending table 10 in the non-extended state.
- the table 10 has, for example, a tabletop 11 with a rectangular outline and a table frame 12 with four table legs 13, 14, 15, 16, which are each located approximately in the corner regions of the tabletop 11 on the table frame 12.
- the rectangular table top 11, which determines the size of the table surface in the non-extended basic state, is also referred to herein as the base plate.
- This base plate 11 has a surface area A, which is increased by a dimension x when the table frame 12 is pulled out and the attachment plates are folded out, as seen in the longitudinal direction of the base plate 11 .
- figure 2 shows the extendable table 10, in which the table frame 12 was first extended in the longitudinal direction before the extension plates are unfolded. You can see that extending the table frame 12 increases the distance between the two table legs 13, 14 on one transverse end area and those 15, 16 on the other transverse end area, which are located on the extended part of the table frame 12, so that the length of the table frame 12 increases seen in the longitudinal direction.
- the two extension plates are in the extended area of the table frame 12 initially folded in a plane that is slightly lower than the plane of the base plate 11, as shown in the view figure 3 can recognize.
- the two folded extension plates are initially on top of each other, so that you can figure 3 looks at the underside of one of the attachment plates 17 on which, as can be seen, there are two reinforcing strips 18, 19 which extend in the longitudinal direction of the attachment plate 17.
- the two reinforcing strips 18, 19 are arranged at a distance from one another when viewed in the transverse direction, with one of the two reinforcing strips 18 reinforcing approximately the central region of the attachment plate 17, while the second reinforcing strip 19 is arranged along a longitudinal edge area of the attachment plate 17, in which the hinges 20 of the folding mechanism, which is used for articulated folding out of the two attachment plates.
- the partially unfolded two extension plates 17, 21 form an angle with one another, as can be seen in FIG figure 5 shown position that the two extension plates 17, 21 are horizontal in their unfolded end position in which they lie in the plane of the base plate 12 and extend it in the longitudinal direction.
- the additional table surface x which is created by the two folded-out extension plates 17, 21, is divided, for example, roughly in half into the surfaces of the two extension plates 17 and 21, which lie against one another along their longitudinal edge 22 and can protrude somewhat beyond the table frame 12 on both sides in the transverse direction.
- FIG. 7 shows an approximately rectangular cross-section and a material thickness that preferably corresponds at least approximately to that of the attachment plate 17, so that in the areas in which the reinforcement strip 18 is attached, the material thickness of the attachment plate 17 is at least approximately doubled, in order to prevent possible distortion of the attachment plate 17 to counteract effectively.
- the reinforcement strip 18 can be fastened to the attachment plate 17, for example, using screws, for which purpose bores 26 are made in the material of the reinforcement strip, which take up such screws.
- the reinforcement strips 18, 19, like the attachment plates 17, 21, are made, for example, of HPL, compact board or a laminate material, as well as of waterproof glued wood materials or plywood.
- the figures 9 and 10 show corresponding views of the second reinforcement strip 19, which is in principle very similar in design to the first reinforcement strip 18 and also has corresponding bores 26 for screw fastening.
- the second reinforcing strip 19 can have a similar material thickness and similar dimensions have like the first reinforcement strip 18 and differs from this only in that it has a straight edge 27 on one side, since it is as shown in FIG figure 6 recognized in the edge area along the longitudinal edge of the attachment plate 17 is attached.
- the respectively opposite end edge of the reinforcement bar 19 is provided with a sloping bevel 29 on both sides of the first reinforcement bar 18 , just like the two end edges.
- FIG 11 shows a view of the underside of the attachment plate 17 and you can clearly see the arrangement of the two reinforcing strips 18, 19.
- the second reinforcing strip 19 attached in the edge area along the longitudinal edge of the attachment plate 17 has a plurality of spaced cutouts 28 along its outer longitudinal edge, with one of these cutouts 28 in figure 13 is shown again on an enlarged scale.
- the cutout 28 has approximately the shape of an upside down "T", ie it is wider in the area at the edge than in the area remote from the edge.
- figure 14 shows a section in the area of in figure 13 Milling 28 shown and you can see different holes 30 and a central slot 31, each serving to accommodate parts of the folding hinge.
- the slot 31 is deeper and extends through the reinforcement strip 19 into the material of the attachment plate 17.
- figure 12 shows again a vertical section through the attachment plate 17 in the area of a reinforcement bar 19 on an enlarged scale in the area of one of the bores 26, into which a screw (not shown here) can be screwed, which can be screwed through the bore 26 in the reinforcement bar 19 to one with this aligned bore 32 in the attachment plate 17 can be screwed into it in order to connect the reinforcing strip 19 to the attachment plate 17.

Description
Die vorliegende Erfindung betrifft einen Ausziehtisch umfassend ein Tischgestell mit üblicherweise vier Tischbeinen, eine Grundplatte, die eine Tischplatte mit einer Fläche von der Größe A definiert, sowie umfassend wenigstens eine durch eine Schwenkbewegung ausklappbare Ansatzplatte, die im ausgeklappten Zustand die Fläche der Tischplatte um ein Maß x vergrößert und die Grundplatte in einer Richtung verlängert.The present invention relates to an extendable table comprising a table frame with usually four table legs, a base plate which defines a table top with an area of size A, and comprising at least one attachment plate which can be folded out by a pivoting movement and which, in the folded out state, increases the area of the table top by a certain amount x enlarged and the base plate lengthened in one direction.
Aus der
Die Ansatzplatten sind in der Regel nur an wenigen Punkten mit dem Tischgestell verbunden. Dies kann dazu führen, dass sich das Plattenmaterial mit der Zeit verzieht. Der Verzug wird nicht nur konstruktiv hervorgerufen, sondern durch Temperatur- und Feuchtigkeitseinflüsse noch verstärkt. Dieser Effekt tritt insbesondere dann auf, wenn der Ausziehtisch für den Außenbereich vorgesehen ist und dadurch den Einflüssen der Witterung ausgesetzt ist.The extension plates are usually only connected to the table frame at a few points. This can cause the sheet material to warp over time. The distortion is not only caused by the design, but is also increased by the influence of temperature and humidity. This effect occurs in particular when the extendable table is intended for outdoor use and is therefore exposed to the effects of the weather.
Ausgehend von dem zuvor geschilderten Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, einen Ausziehtisch zur Verfügung zu stellen, bei dem der genannte Verzug der Ansatzplatten vermieden wird.Proceeding from the prior art described above, the object of the present invention is to provide an extendable table in which the above-mentioned distortion of the attachment plates is avoided.
Die Lösung der vorgenannten Aufgabe liefert ein Ausziehtisch der eingangs genannten Art mit den Merkmalen des Anspruchs 1. Erfindungsgemäß ist vorgesehen, dass unterseitig an wenigstens einer Ansatzplatte wenigstens eine Verstärkungsleiste angebracht ist. Dadurch wird im Bereich der Verstärkungsleiste die Materialstärke der Ansatzplatten wesentlich erhöht, somit deren Stabilität vergrößert und Verzug der Ansatzplatten auch bei Witterungseinflüssen vermieden.The solution to the aforementioned problem is provided by an extendable table of the type mentioned at the beginning with the features of claim 1. According to the invention it is provided that at least one reinforcement strip is attached to at least one attachment plate on the underside. As a result, the material thickness of the attachment plates is significantly increased in the area of the reinforcement strip, thus increasing their stability and avoiding warping of the attachment plates even under the influence of the weather.
Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung ist die Verstärkungsleiste an der Ansatzplatte angeschraubt. Dies ermöglicht eine vergleichsweise einfache Herstellung der stabileren und gegen Verzug geschützten Ansatzplatten. In der Regel erfolgt die Verschraubung der Verstärkungsleiste an der Ansatzplatte an mehreren Stellen mit Hilfe geeigneter Schrauben, die in den Holzwerkstoff der Verstärkungsleiste und der Ansatzplatte hinein geschraubt werden können. Gegebenenfalls ist es vorteilhaft, zumindest in die Verstärkungsleiste Bohrungen einzubringen, um den Schraubvorgang zu erleichtern.According to a preferred development of the present invention, the reinforcement bar is screwed to the attachment plate. This allows a comparatively simple production of the more stable attachment plates, which are protected against warping. As a rule, the reinforcement bar is screwed to the attachment plate at several points using suitable screws that can be screwed into the wooden material of the reinforcement bar and the attachment plate. It may be advantageous to drill holes at least in the reinforcing strip in order to facilitate the screwing process.
Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung die Verstärkungsleiste eine Materialstärke aufweist, die wenigstens der Materialstärke der Ansatzplatte entspricht. Um einen effektiven Schutz der Ansatzplatten gegen Verzug zu erreichen, sollte die Verstärkungsleiste nicht zu dünn sein. Die Erfahrung sowie Versuche im Rahmen er vorliegenden Erfindung haben gezeigt, dass es vorteilhaft ist, wenn die Verstärkungsleiste die ursprüngliche Materialstärke der Ansatzplatte wenigstens in etwa verdoppelt.According to a preferred development of the present invention, the reinforcement strip has a material thickness that corresponds at least to the material thickness of the attachment plate. In order to achieve effective protection of the attachment plates against warping, the reinforcement bar should not be too thin. Experience and tests within the scope of the present invention have shown that it is advantageous if the reinforcement strip at least approximately doubles the original material thickness of the attachment plate.
Eine bevorzugte Weiterbildung der vorliegenden Erfindung sieht vor, dass die Verstärkungsleiste wenigstens eine Materialstärke von etwa 10 mm aufweist, vorzugsweise eine Materialstärke von wenigstens etwa 15 mm. Hier spielt natürlich auch die Materialstärke der Ansatzplatte selbst eine Rolle. Es kann sich beispielsweise um eine Kompaktplatte mit einer Materialstärke von etwa 11 mm bis etwa 15 mm, beispielsweise im Bereich von etwa 13 mm handeln. Die Verstärkungsleiste kann dann beispielsweise eine Materialstärke von 10 mm oder mehr, besonders bevorzugt von 15 mm oder mehr, beispielsweise etwa zwischen 15 mm und 20 mm aufweisen, so dass die Materialstärke der Ansatzplatte im Bereich der Verstärkungsleisten verdoppelt oder mehr als verdoppelt wird, was für eine effektive Stabilisierung ausreichend ist.A preferred development of the present invention provides that the reinforcement strip has a material thickness of at least approximately 10 mm, preferably a material thickness of at least approximately 15 mm. Of course, the thickness of the material also plays a role here the attachment plate itself plays a role. For example, it can be a compact plate with a material thickness of about 11 mm to about 15 mm, for example in the range of about 13 mm. The reinforcement bar can then have a material thickness of 10 mm or more, particularly preferably 15 mm or more, for example between 15 mm and 20 mm, so that the material thickness of the attachment plate in the area of the reinforcement bars is doubled or more than doubled, which effective stabilization is sufficient.
Vorzugsweise weist die Verstärkungsleiste wenigstens eine Ausfräsung auf, die ein Klappscharnier aufnimmt. Das Klappscharnier oder mehrere solcher Klappscharniere werden benötigt, um die Ansatzplatte gelenkig mit einer weiteren Ansatzplatte zu verbinden, wobei dann die beiden Ansatzplatten in einer Schwenkbewegung um eine Drehachse aus einer quasi versenkten Stellung in die Gebrauchslage ausgeklappt werden können, in der sie in der Ebene der Grundplatte liegen und deren Fläche-und somit die Tischplatte-- in einer Richtung um ein definiertes Maß vergrößern. Durch die Ausfräsung liegt das Klappscharnier dann versenkt oder zumindest teilweise versenkt in der Verstärkungsleiste. Gemäß dieser vorteilhaften Weiterbildung der Erfindung nutzt man somit die Verstärkungsleiste für die Befestigung eines Klappscharniers, was durch die erhöhte Materialstärke den Einsatz von stabileren Beschlägen ermöglicht.Preferably, the reinforcement strip has at least one cutout that accommodates a folding hinge. The folding hinge or several such folding hinges are required in order to connect the attachment plate in an articulated manner to another attachment plate, in which case the two attachment plates can then be folded out in a pivoting movement about an axis of rotation from a quasi-sunken position into the position of use, in which they are in the plane of the Base plate lie and their surface - and thus the table top - increase in one direction by a defined amount. The folding hinge is then sunk or at least partially sunk in the reinforcement strip due to the milling. According to this advantageous further development of the invention, the reinforcing bar is used to attach a folding hinge, which allows the use of more stable fittings due to the increased material thickness.
Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung ist somit die Ansatzplatte zweiteilig ausgebildet und besteht aus zwei gelenkig miteinander verbundenen Teilplatten, da sich bei dieser konstruktiven Lösung die beiden Ansatzplatten bei Nichtgebrauch besser in dem Tischgestell unterbringen lassen und auch die Handhabung beim Ausklappen der Ansatzplatten einfacher ist, wenn diese einzeln eine geringere Größe und somit ein geringeres Gewicht aufweisen, als bei Verwendung nur einer einzelnen größeren Ansatzplatte.According to a preferred development of the present invention, the attachment plate is designed in two parts and consists of two part plates connected to one another in an articulated manner, since with this structural solution the two attachment plates can be better accommodated in the table frame when not in use and handling when folding out the attachment plates is also easier. if these individually have a smaller size and thus a lower weight than when using only a single larger attachment plate.
Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung ist die Ansatzplatte an mindestens einer Stelle mit einer Drehachse verbunden, welche wiederum an dem Tischgestell gelagert ist. Durch Ausklappen und schwenken um diese Drehachse wird dann die Ansatzplatte, bzw. die Gesamtheit der beiden miteinander verbundenen Ansatzplatten in die Gebrauchslage geschwenkt. Diese Art der Konstruktion eines Ausziehtisches mit zwei schwenkbaren, ausklappbaren Ansatzplatten ist an sich aus dem Stand der Technik bekannt. In der vorliegenden Erfindung geht es daher um die Stabilisierung der Ansatzplatten mit Hilfe einer oder mehrerer Verstärkungsleisten, bevorzugt aus HPL, wie auch wasserfrei verleimten Holzwerkstoffen oder Sperrholz.According to a preferred development of the present invention, the attachment plate is connected at least at one point to an axis of rotation, which in turn is mounted on the table frame. By unfolding and pivoting about this axis of rotation, the attachment plate, or the entirety of the two attachment plates connected to one another, is then pivoted into the position of use. This type of construction of an extendable table with two pivotable, fold-out attachment plates is known per se from the prior art. The present invention is therefore about stabilizing the attachment plates with the help of one or more reinforcement strips, preferably made of HPL, as well as water-free glued wood materials or plywood.
Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung verbindet wenigstens ein Klappscharnier die miteinander verbundenen Teilplatten gelenkig miteinander. In der Regel sind es mehrere solcher Klappscharniere, die jeweils mit Abstand zueinander etwa in einer Flucht liegen, vorzugsweise entlang oder in der Nähe einer Kante, insbesondere einer Längskante, an der die beiden Teilplatten der Ansatzplatte gelenkig miteinander verbunden sind.According to a preferred development of the present invention, at least one folding hinge connects the interconnected partial panels to one another in an articulated manner. As a rule, there are several such folding hinges, which are approximately aligned at a distance from one another, preferably along or near an edge, in particular a longitudinal edge, at which the two partial plates of the attachment plate are connected to one another in an articulated manner.
Vorzugsweise sind an einer Ansatzplatte wenigstens zwei Verstärkungsleisten angebracht. Bei Anbringung mehr als einer Verstärkungsleiste kann man eine noch bessere Stabilisierung der Ansatzplatte erzielen, insbesondere kann man diese so in verschiedenen Bereichen verstärken, in denen besonders mit dem Auftreten von Verzug zu rechnen ist, ohne dabei zu viel Material einzusetzen, so dass eine allzu große Erhöhung des Gewichts durch die Verstärkung der Ansatzplatte vermieden wird.Preferably, at least two reinforcement strips are attached to an attachment plate. By attaching more than one reinforcement bar, you can achieve even better stabilization of the attachment plate, in particular you can reinforce it in different areas where warpage is particularly likely to occur, without using too much material, so that an excessively large Increase in weight is avoided by strengthening the attachment plate.
Gemäß einer möglichen Ausführungsvariante der Erfindung sind zwei Verstärkungsleisten an einer Ansatzplatte mit Abstand zueinander angebracht, vorzugsweise in zueinander etwa paralleler Ausrichtung. Beispielsweise kann man eine dieser Verstärkungsleisten mehr mittig unter der Ansatzplatte anbringen und die andere mehr im Randbereich, insbesondere in der Nähe der Kante, über die die Ansatzplatte gelenkig mit einer weiteren Teilplatte verbunden ist. Je nach Größe der jeweiligen Verstärkungsleisten kann man natürlich auch beispielsweise drei oder mehr Verstärkungsleisten anbringen, die dann schmaler oder kürzer ausgeführt sein können. Hier lässt sich ein Optimum hinsichtlich Größe und Anzahl der Verstärkungsleisten finden, bei dem man einerseits eine effektive Verstärkung und Verbesserung der mechanischen Eigenschaften der Ansatzplatte erzielt, andererseits aber auch mit nicht allzu großem zusätzlichen Material arbeitet, um eine zu starke Gewichtserhöhung der Ansatzplatte zu vermeiden, die deren Handhabung erschweren und das Tischgestell und die Klappscharniere belasten würde.According to a possible variant embodiment of the invention, two reinforcing strips are attached to an attachment plate at a distance from one another, preferably in an approximately parallel orientation to one another. For example, one of these reinforcement strips can be attached more centrally under the attachment plate and the other more in the edge area, in particular in the vicinity of the edge via which the attachment plate is connected in an articulated manner to another sub-plate. Depending on the size of the respective reinforcement strips, it is of course also possible, for example, to attach three or more reinforcement strips, which can then be made narrower or shorter. Here an optimum can be found in terms of size and number of reinforcement bars, in which on the one hand an effective reinforcement and improvement of the mechanical properties of the attachment plate is achieved, but on the other hand not too much additional material is used in order to avoid an excessive increase in weight of the attachment plate. which would make their handling more difficult and put a strain on the table frame and folding hinges.
Gemäß einer bevorzugten Weiterbildung der Erfindung erstreckt sich wenigstens eine Verstärkungsleiste in Längsrichtung der Ansatzplatte und/oder die Verstärkungsleiste erstreckt sich über mehr als die Hälfte der Länge der Ansatzplatte, besonders bevorzugt über den überwiegenden Teil der Länge der Ansatzplatte. Da die Ansatzplatte in der Regel rechteckig ist, tritt der Verzug am ehesten in der Längsrichtung auf, die die größere Abmessung hat. Daher bietet es sich an, die Verstärkungsleisten ebenfalls in Längsrichtung der Ansatzplatte auszurichten. Die Verstärkungsleiste muss sich nicht über die gesamte Länge der Ansatzplatte erstrecken, aber es ist vorteilhaft, wenn die Verstärkungsleiste nicht zu kurz ist, im Verhältnis zur Länge der Ansatzplatte, da ansonsten der gewünschte Effekt der mechanischen Stabilisierung nicht in ausreichendem Maße erzielt wird.According to a preferred development of the invention, at least one reinforcement bar extends in the longitudinal direction of the attachment plate and/or the reinforcement bar extends over more than half the length of the attachment plate, particularly preferably over most of the length of the attachment plate. Because the heel plate is typically rectangular, warpage is most likely to occur in the longitudinal direction, which has the larger dimension. It is therefore advisable to also align the reinforcement strips in the longitudinal direction of the attachment plate. The reinforcement strip does not have to extend over the entire length of the extension plate, but it is advantageous if the reinforcement strip is not too short in relation to the length of the extension plate, otherwise the desired effect of mechanical stabilization will not be achieved to a sufficient extent.
Vorzugsweise weist bei zwei Verstärkungsleisten nur eine der Verstärkungsleisten ein oder mehrere Ausfräsungen auf, die jeweils ein Klappscharnier aufnehmen. Die Ausfräsungen benötigt man nur bei Verwendung einer Verstärkungsleiste, die sich in der Nähe der Kante befindet, um die die Ansatzplatte mit einer weiteren Teilplatte schwenkbar verbunden ist. Wenn man eine Verstärkungsleiste entlang der Kante an der Ansatzplatte anbringt, ist es jedoch vorteilhaft, mindestens eine weitere Verstärkungsleiste mit Abstand zu der ersten Verstärkungsleiste mehr im mittleren Bereich der Ansatzplatte anzubringen, da andernfalls eine zu große Fläche der Ansatzplatte ohne Verstärkung bleibt und damit der erwünschte Effekt der mechanischen Stabilisierung nur unzureichend erreicht wird.In the case of two reinforcement strips, preferably only one of the reinforcement strips has one or more cutouts, each of which accommodates a folding hinge. The cut-outs are only required when using a reinforcement strip which is located near the edge around which the attachment plate is pivotably connected to another sub-plate. However, when attaching a reinforcement bar along the edge of the attachment plate, it is advantageous to attach at least one further reinforcement bar at a distance from the first reinforcement bar more in the middle area of the attachment plate, otherwise too large an area of the attachment plate will remain without reinforcement and thus the desired one Effect of mechanical stabilization is only insufficiently achieved.
