Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Klapptisches oder einer klappbaren Sitzbank mit beidseitig im Endbereich ihrer Schmalseiten je einem wahlweise etwa senkrecht in Nutzungsstellung oder aber - parallel zur Ebene der Unterseite der Tisch- bzw. Bankplatte - in Stapelstellung verbringbar angeordneten verschwenkbaren Stützfuss, der jeweils durch eine mit ihm verbundene, verschwenkbare Stützstrebenkonstruktion in ein die eingestellte Stellung sicherndes Sperrelement einrastbar ist, wobei das Sperrelement in einem solchen Abstand von der Schwenkachse des Stützfusses an der Unterseite der Tisch- oder Bankplatte angeordnet ist, dass in Standstellung die Endbegrenzung der Stützstrebenkonstruktion und in Stapelstellung der Eingriffsteg des Stützfusses einrastbar ist.The invention relates to a method for producing a folding table or a folding bench with either side in the end region of its narrow sides either one approximately vertically in the use position or - parallel to the plane of the underside of the table or bench top - pivotable support foot arranged in a stackable position, each of which by means of a pivotable support strut construction connected to it, it can be snapped into a locking element securing the set position, the locking element being arranged at such a distance from the pivot axis of the support foot on the underside of the table or bench plate that in the standing position the end limitation of the support strut construction and in Stacking position of the engagement web of the support foot is clickable.

Tische bzw. Bänke dieser Art sind seit langem bekannt und in vielen Gartenwirtschaften, auf Festplätzen, -wiesen oder dergleichen zu finden.Tables and benches of this type have been known for a long time and can be found in many garden inns, on fairgrounds, meadows or the like.

So sind z.B. durch die österreichische Patentschrift AT-B-345 504 Vorrichtungen bekanntgeworden, die zumindest in ihrer Funktion den nach den oben genannten Verfahren hergestellten Tischen und Bänken entsprechen.For example, through the Austrian patent specification AT-B-345 504 devices are known which correspond at least in their function to the tables and benches produced by the above-mentioned processes.

Die Nachteile dieser bekannten Konzeptionen liegen einmal in der Vielteiligkeit der Stützfusskonstruktion und zum anderen in der aus Gewichtsgründen nicht einstellbaren befriedigenden Verwindungssteifigkeit.The disadvantages of these known concepts lie on the one hand in the multiplicity of the support foot construction and on the other hand in the satisfactory torsional rigidity which cannot be adjusted for reasons of weight.

Der Stützfuss ist eine Rahmenkonstruktion, die in ihrem zur Tischplatte gerichteten, schmalseitigen Bereich durch einen Kreuzverband ausgesteift und in ihrem Aufstandsbereich durch ein nach innen gebogenes, eine Fussleiste bildendes Profil abgeschlossen ist. Knapp unterhalb der Auskreuzung ist zwischen den mit ihrer offenen Seite zueinander gerichteten Winkelprofilen des Rahmens liegend an einer durch die gegenüberliegenden Schenkel führende Welle eine V-förmige Gabelstütze angeordnet, die in ihrem spitzen Bereich durch einen in ein an der Unterseite der Tisch- bzw. Bankplatte angeordnetes Spreizelement führbaren Rastbolzen verbunden ist.The support leg is a frame construction, which is stiffened by a cross brace in its narrow side area facing the table top and is closed in its contact area by an inwardly curved profile that forms a baseboard. Just below the crossover, a V-shaped fork support is arranged between the angular profiles of the frame, which face each other with their open sides facing each other, on a shaft leading through the opposite leg, which in its pointed area is inserted into one on the underside of the table or bench top arranged spreading element is connected to feasible locking bolt.

An der Unterseite der Platte ist die den Stützfuss bildende Rahmenkonstruktion mit dieser- in der Regel über ein Zwischenglied verschwenkbar - angeordnet. Des weiteren ist an dem Stützfuss ein Eingriffsteil zu dessen Lagefixierung in Stapelstellung an der Platte ausgebildet.On the underside of the plate, the frame structure forming the support foot is arranged with it, which can generally be pivoted via an intermediate member. Furthermore, an engagement part for fixing its position in the stacked position on the plate is formed on the support foot.

Die das eigentliche Stützteil der den Stützfuss bildenden Konstruktion wird dabei - wie bereits den vorstehenden Ausführungen zu entnehmen ist-aus insgesamt fünf Einzelteilen, d.h. aus zwei, die seitliche Begrenzung bildenden Winkelprofilen, den beiden, einen Kreuzverband bildenden Flachprofilen sowie dem eine Fussleiste bildenden, zum Stützfussinnern gerichtet eingebogenen Flachprofil gebildet, wobei der Verbund dieser Teile in der Regel durch Schweissverbindungen hergestellt ist. Die Herstellung dieses aus einer Mehrzahl einzeln zu verbindenden Glieder zu bildenden Stützteiles des Stützfusses ist nicht nur zeitaufwendig, sondern auch statisch nicht befriedigend, da neben dem im Bereich des Anschlusses an die Tisch- bzw. Bankplatte liegenden Kreuzverbandes lediglich die aus einem Flachprofil gebildete Fussleiste im längeren, zur Aufstellebene gerichteten Teil des Rahmens eine nur unwesentliche Verstärkung gegen seitliche, insbesondere Stossbelastungen, geben kann.The actual support part of the construction forming the support foot is - as can already be seen from the above explanations - from a total of five individual parts, i.e. formed from two angle profiles forming the lateral boundary, the two flat profiles forming a cross structure and the flat profile forming a baseboard and directed towards the inside of the supporting foot, the connection of these parts generally being produced by welded connections. The production of this support part of the support foot, which is to be formed from a plurality of individually connected links, is not only time-consuming, but also statically unsatisfactory, since in addition to the cross structure lying in the region of the connection to the table or bench top, only the baseboard formed from a flat profile in the longer part of the frame directed towards the installation level can provide only insignificant reinforcement against lateral, in particular shock loads.

Dies berücksichtigend ist es Aufgabe dieser Erfindung, ein Verfahren nach der eingangs gegebenen Definition zu nennen, bei dem die Stützfüsse, insbesondere das eigentliche Stützteil, bildenden Teile auf ein Minimum, bei gleichzeitiger Minderung des Arbeitsaufwandes, reduziert sind und das Stützteil den statischen Erfordernissen besser gerecht wird.Taking this into account, it is the object of this invention to name a method according to the definition given at the beginning, in which the support legs, in particular the actual support part, forming parts are reduced to a minimum, while at the same time reducing the workload, and the support part better meets the structural requirements becomes.

Die erfindungsgemässe Lösung dieser Aufgabe sieht vor, dass das Stützteil des Stützfusses aus einer rechteckigen Platine geschnitten wird, und anschliessend gleichzeitig oder schrittweise

  • a) mit mehreren, unterteilt oder gegliedert - hierbei einen parallel zu einer Schmalseite gerichteten Eingriffssteg bildend - Entlastungausnehmungen,
  • b) mit zwei an einer Schmalseite in gegenüberliegenden Eckbereichen rechtwinkligen, gleichdimensionierten Ausklinkungen,
  • c) mit einer an der gegenüber der die Ausklinkungen aufweisenden Schmalseite liegenden Schmalseite, parallel zu dieser, gebildeten Ausnehmung, beidseitig im Überstand gelochte Augen gleicher Dimensionierung aufweisend,
  • d) sowie etwa in Höhe des Eingriffssteges abstandsgleich zu den gelochten Augen mit zwei weiteren Auslochungen versehen wird, dass die Platine entlang der durch die Ausklinkungen lagemarkierten Biegekanten nach einer Richtung um 90° abgekantet wird, dass das Tragprofil für die Tisch- bzw. Bankplatte durch die Augen des Stützfusses reichende Schwenkbolzen mit dem Stützfuss schwenkbar verbunden wird und dass die Stützstrebe durch durch die Auslochungen des Stützfusses reichende Schwenkbolzen mit dem Stützfuss schwenkbar verbunden wird.
The solution to this problem according to the invention provides that the supporting part of the supporting foot is cut from a rectangular board, and then simultaneously or step by step
  • a) with several, subdivided or structured - in this case forming an engagement web oriented parallel to a narrow side - relief recesses,
  • b) with two notches which are rectangular and of equal dimensions on opposite sides in a corner area,
  • c) with eyes of the same dimension, perforated on both sides in the overhang, on the narrow side opposite the narrow side having the notches, parallel to this recess,
  • d) and at about the same height as the engagement bar, two holes are made at the same distance as the perforated eyes, so that the circuit board is bent in a 90 ° direction along the bending edges marked by the notches, so that the support profile for the table or bench top passes through swivel bolts reaching the eyes of the support foot are pivotally connected to the support foot and that the support strut is pivotally connected to the support foot by swivel bolts reaching through the holes in the support foot.

Dieses Verfahren zur Herstellung eines Stützteiles durch Einbringung von gewichtsentlastenden Ausschnitten sowie allen erforderlichen Ausklinkungen und Lochungen in eine rechtwinklige Platine durch ein einheitliches Schnittwerkzeug reduziert die Zahl der erforderlichen Einzelteile für das Stützteil von fünf Teilen auf einen Teil.This method of producing a support part by introducing weight-relieving cutouts and all the necessary notches and perforations in a rectangular circuit board by means of a uniform cutting tool reduces the number of individual parts required for the support part from five parts to one part.

Die in Fortsetzung zu vollziehende Abkantung - die fallweise in Verbindung mit der später erwähnten Versickung von verbleibenden Stegen durchgeführt wird - versteift das Stützteil des Stützfusses in so erheblichem Masse, dass trotz eines in der Regel geringeren Gesamtgewichtes, eine wesentlich höhere Steifigkeit des Stützfusses insbesondere auch gegen seitliche Stossbelastungen gegeben ist. Selbstverständlich ist es in diesem Zusammenhang zweckmässig und die Festigkeit fördernd, wenn die rechtwinkligen Stosskanten der U-förmig umlaufenden Abgrenzstreifen verschweisst werden. Die gleichbleibende exakte Lochung der Gelenkwellen und die ebenfalls gleichbleibend exakte Abkantung ermöglicht es, auf durchgehende Tragwellen für den Anschluss der Stützstrebe und des Tragprofiles für die Tisch- bzw. Bankplatte zu verzichten und die Verbindung dieser Teile über einzelne Schwenkbolzen herzustellen.The bend to be carried out in continuation - which is carried out occasionally in connection with the infiltration of remaining webs mentioned later - stiffens the support part of the support foot to such an extent that, despite a generally lower overall weight, a significantly higher stiffness of the support foot in particular also against lateral shock loads are given. In this context, it is of course expedient and strengthening if the right-angled abutting edges of the U-shaped circumferential border strips are welded. The constant exact perforation of the cardan shafts and the also consistently precise bending makes it possible to dispense with continuous support shafts for the connection of the support strut and the support profile for the table or bench top and to connect these parts via individual pivot bolts.

Zum Abstand zwischen der Anlenkung des Stützfusses und dem Sperrelement, die beide an der Unterseite der Tisch- bzw. Bankplatte angeordnet sind, und zum Abstand der Anlenkung des Stützfusses und des an ihm ausgebildeten Eingriffsstegs sowie zur in die Ebene projektierten Länge bei winklig angestellten Stützstreben ist festzuhalten, dass der Abstand zwischen den das Tragprofil für die Befestigung der Tisch- oder Bankplatte vorgesehenen Augen und dem mit ihrer Unterseite verbundenen Sperrelement gleich dem Abstand zwischen den Augen und der Mittellinie des Eingriffssteges und gleich dem Längenmass der ebenen Projektion der winklig angestellten, in das Sperrelement eingreifenden Stützstrebe eingestellt wird.The distance between the articulation of the support foot and the locking element, both of which are arranged on the underside of the table or bench top, and the distance between the articulation of the support foot and the engaging web formed on it, as well as the projected length in the plane for angled support struts note that the distance between the eyes provided for the attachment of the table or bench top and the locking element connected to their underside is equal to the distance between the eyes and the center line of the engagement web and equal to the length of the flat projection of the angled, into which Locking element engaging support strut is set.

Um die zur Unterseite gerichtete parallele Anlage des Stützfusses zu sichern, ist vorgesehen, dass der zur Fixierung des gegen die Tisch- bzw. Bankplatte geklappten Stützfusses vorgesehene Eingriffssteg etwa in Höhe und Richtung der Abkantungen der Platine ausgebogen wird.In order to secure the parallel contact of the support foot directed towards the underside, it is provided that the engagement web provided for fixing the support foot folded against the table or bench plate is bent out approximately in the height and direction of the folds of the board.

Zur Herstellung der Stützstrebe ist zu bemerken, dass diese aus einem Flachprofil hergestellt wird, das in seinem mittleren Bereich in seiner Breite durch Ausklinkung in der Regel symmetrisch verengt wird und dessen Ecken in diesem mittleren Bereich angerundet werden, und dass die Stützstrebe zu einer zwischen den Abkantungen der Platine greifenden Gabel gebogen wird.For the manufacture of the support strut, it should be noted that this is made from a flat profile, the width of which is generally narrowed symmetrically in its central region by notching and the corners of which are rounded in this central region, and that the support strut becomes one between the Bending the board-engaging fork is bent.

Zweckmässigerweise wird die gabelformaufweisende Stützstrebe so gebogen, dass dem mittleren Bereich sich senkrecht jeweils parallel versetzte durch eine winklig nach aussen gerichtete Stufe verbundenen Ebenen anschliessen.The fork-shaped support strut is expediently bent in such a way that the central region adjoins each other vertically offset in parallel by planes connected by an angled outward step.

Zur Ausbildung der Aufstandsfläche des Stützfusses wird vorgeschlagen, dass der entlang der Biegekante verlaufende abgekantete Streifen in Richtung einer ihm zugerichteten mittig zur Schmalseite angeordneten durch den abgekanteten Streifen begrenzte Ausnehmung eingebogen wird.To form the contact area of the support foot, it is proposed that the folded strip running along the bending edge is bent in the direction of a recess arranged in the center of the narrow side and delimited by the folded strip.

Durch diese Ausbildung wird erreicht, dass beidseitig an jeder Kante der aufstehenden Schmalseite eine separate Aufstandsfläche entsteht, die die wackelfreie Aufstellung der Tische bzw. Bänke erleichtert.This design ensures that a separate contact surface is created on both sides of each edge of the upstanding narrow side, which facilitates the wobble-free installation of the tables or benches.

Wie bereits eingangs erwähnt, ist vorgesehen, dass die durch Ausnehmungen und Ausklinkungen reduzierte Fläche der Platine partiell mit Sikkungen versehen wird.As already mentioned at the beginning, it is provided that the area of the board which is reduced by recesses and notches is partially provided with sinkings.

Durch diese Massnahme lassen sich höhere Festigkeitswerte bzw. ein geringeres Werkstoffgewicht einstellen.This measure enables higher strength values or a lower material weight to be set.

Des weiteren ist vorgesehen, dass nach Auflagerung der rechteckigen Platine auf die Matritze einer Presse Ausnehmungen, Ausklinkungen und Lochungen hergestellt werden, und dass anschliessend die gelochte Platine durch einen den Verlauf der Sickungen mitbestimmenden Biegestempel für die endgültige Formgebung des Stützteiles des Stützfusses gemeinsam geformt wird.Furthermore, it is provided that after the rectangular board has been placed on the die of a press, recesses, notches and perforations are made, and that the perforated board is then jointly formed by a bending punch, which also determines the course of the beads, for the final shaping of the support part of the support foot.

Die den Stützfuss bildende Platine 1 ist mit innenliegenden, zur Gewichtserleichterung angeordneten Ausnehmungen 2 versehen und weist an den unteren Ecken rechtswinklige Ausklinkungen 3 aus, deren Kanten den Verlauf der fortsetzenden Biegekanten 3.1 und 3.2 bestimmen. Eine weitere Ausklinkung 4 ist an der oberen Schmalseite der Platine 1 angeordnet, wobei die Tiefe dieser Ausklinkung die Höhe der hervorstehenden Augen 5 bestimmen, denen nach vollzogener Abkantung bzw. Biegung das Tragprofil 6 über Schwenkbolzen 7 verbunden ist. Das Tragprofil 6 ist ein beiderseitig an seinen Enden abgeschlossenes Winkelprofil, das mit der Tischplatte 16 verbunden ist. Zwei weitere, in den Längsrandbereichen angeordnete Lochungen 8 dienen zur verschwenkbaren Befestigung der später beschriebenen Stützstrebenkonstruktion durch die Schwenkbolzen 9. Um im Bereich hoher statischer Beanspruchung die Festigkeit des Stützfusses 10 zu verstärken, sind Einsickungen 11 vorgesehen, wobei die Gestaltung der Sicken 11, wie erwähnt, vergrössert durch Figur 4 dargestellt sind.The circuit board 1 forming the support foot is provided with internal recesses 2 arranged to reduce weight and has right-angled notches 3 at the lower corners, the edges of which determine the course of the continuing bending edges 3.1 and 3.2. A further notch 4 is arranged on the upper narrow side of the board 1, the depth of this notch determining the height of the protruding eyes 5, to which the support profile 6 is connected via pivot bolts 7 after the bend or bend has been completed. The support profile 6 is an angular profile closed at both ends at its ends, which is connected to the table top 16. Two further perforations 8 arranged in the longitudinal edge regions serve for the pivotable fastening of the support strut construction described later by means of the pivot bolts 9. In order to increase the strength of the support foot 10 in the area of high static loads, sags 11 are provided, the configuration of the beads 11, as mentioned , enlarged by Figure 4 are shown.

Die Stützstrebe 12 ist ein aus einem Flachprofil oder aus einem Blech angefertigtes Teil, das in seinem mittleren Bereich 13 in seiner Breite durch beidseitige Ausklinkungen symmetrisch verengt ist und dessen Ecken in diesem Bereich angerundet sind. Das Teil wird anschliessend gemäss der in Figur 5 dargestellten Projektion gebogen und ist bei aufgestelltem Tisch (gern. Figur 6) in ein Sperrelement 14 einrastbar. Bei gegen die Tischplatte 16 geklapptem Stützfuss 10 greift der Eingriffsteg 15 in das Sperrelement 14 ein, d.h., die ebene Projektion der winklig angestellten in das Sperrelement 14 greifenden Stützstrebe 12 weist die gleiche Länge auf wie der Abstand zwischen den Augen 5 und der Mittellinie der Stützstrebe 12.The support strut 12 is a part made from a flat profile or from a sheet metal, the width of which is narrowed symmetrically in its central region 13 by notches on both sides and the corners of which are rounded in this region. The part is then bent in accordance with the projection shown in FIG. 5 and can be snapped into a locking element 14 when the table is upright (like FIG. 6). When the support leg 10 is folded against the table top 16, the engagement web 15 engages in the locking element 14, that is to say the plane projection of the angled support strut 12 which engages in the locking element 14 the same length as the distance between the eyes 5 and the center line of the support strut 12.

Um ein vollständiges Beiklappen des Stützfusses 10 an die Unterseite der Tisch- bzw. Bankplatte zu ermöglichen, ist der die Fixierung bewirkende Eingriffsteg 15 etwa in Höhe und Richtung der seitlichen Abkantung der Platine 1 ausgebogen. Um die Standsicherheit zu erhöhen, ist der entlang der Biegekante 3.2 abgekantete Streifen 17 in Richtung einer ihm zugerichteten mittigen Ausnehmung 2 eingebogen, so dass beidseitig je eine separate Aufstandsfläche entsteht.In order to enable the support foot 10 to be folded completely onto the underside of the table or bench top, the engaging crosspiece 15 which fixes the base 1 is bent out approximately in the height and direction of the side fold. In order to increase the stability, the strip 17 bent along the bending edge 3.2 is bent in the direction of a central recess 2 facing it, so that a separate contact surface is created on each side.
