Description

Die Erfindung bezieht sich auf eine Verschlußmechanik für eine Halteeinrichtung für gelochte lose Blätter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a locking mechanism for a holding device for perforated loose sheets according to the preamble of claim 1.

Eine solche Verschlußmechanik wurde z.B. durch die GB 1446 A.D. 1905 A bekannt. Bei dieser bekannten Mechanik weist die Bügelleiste an ihren seitlichen Randbereichen abgewinkelte Laschen auf, die mit Bohrungen versehen sind, die von einer in aufgekanteten Laschen der Grundplatte gehaltenen Achse durchsetzt sind, die als Schwenkachse dient. Auf dieser Achse ist eine Schraubenfeder aufgeschoben, die mit ihren beiden freien Enden an der Grundplatte und der Bügelleiste abgestützt ist und für die erforderliche Vorspannung der Bügelleiste in deren der offenen Stellung der Dorne entsprechenden Lage sorgt.Such a locking mechanism was e.g. through the GB 1446 A.D. Known in 1905 A. In this known mechanics points the ironing bar angled at its lateral edge areas Tabs that are provided with holes that from a in interpenetrated tabs of the base plate held by the axis are used as a pivot axis. There is one on this axis Coiled spring pushed on with its two free ends the base plate and the ironing board is supported and for the required pretension of the ironing board in the open Position of the mandrels appropriate position ensures.

Zum Schließen der Dorne ist ein zweiarmiger Hebel vorgesehen, der in seiner Schließstellung mit seinem einen Arm in einem Normalabstand von der Schwenkachse auf die Oberseite der Bügelleiste drückt und diese entgegen der Kraft der Feder in ihrer Schließlage hält.A two-armed lever is provided to close the mandrels, in the closed position with one arm in a normal distance from the swivel axis to the top of the Presses ironing board and this against the force of the spring holds their closed position.

Der Nachteil dieser Lösung liegt in der relativ aufwendigen Konstruktion und dem hohen Montageaufwand, der zur Zusammenstellung dieser bekannten Verschlußmechanik erforderlich ist. Dazu trägt auch die vorgesehene Schraubenfeder erheblich bei.The disadvantage of this solution is that it is relatively complex Construction and the high assembly effort required for the compilation this known locking mechanism is required. To the proposed coil spring also contributes significantly.

Weiters wurde durch die DE 816 689 C eine Verschlußmechanik bekannt, bei der die Bügelleiste mittels aus der Grundplatte ausgebogener und Durchbrüche der Bügelleiste durchsetzender Lappen gehalten ist, die die Bügelleiste übergreifen. Dabei ist die Bügelleiste mittels einer Blattfeder gegen deren der offenen Stellung der Dorne entsprechenden Lage vorgespannt.Furthermore, DE 816 689 C has a locking mechanism known, in which the ironing bar by means of bent out of the base plate and breakthroughs of the flap passing through the ironing board is held, which overlap the ironing board. Here is the ironing board by means of a leaf spring against their open position the position corresponding to the mandrels.

Auch bei dieser Lösung ergibt sich ein sehr erheblicher Montageaufwand, wobei sich überdies das Problem ergibt, daß die Lappen nach dem Aufstecken der Bügelleiste noch abgebogen werden müssen und dabei für ein ausreichend großes Spiel gesorgt werden muß, um eine leichte Schwenkbarkeit der Bügelleiste sicherstellen zu können. With this solution, too, there is a very considerable assembly effort, the problem also arises that the lobes can still be bent after attaching the ironing board must be ensured and a sufficiently large game must ensure that the ironing board can be swiveled easily to be able to.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Verschlußmechanik der eingangs erwähnten Art vorzuschlagen, die einen einfachen Zusammenbau ihrer Teile ermöglicht.The aim of the invention is to avoid these disadvantages and to propose a locking mechanism of the type mentioned at the outset, which enables easy assembly of your parts.

Erfindungsgemäß wird dies bei einer Verschlußmechanik der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is the case with a locking mechanism type mentioned by the characterizing features of the claim 1 reached.

Durch die vorgeschlagenen Maßnahmen erübrigt sich die Herstellung und die Montage einer separaten Feder, wie sie bei den bisherigen Lösungen erforderlich ist. Außerdem erübrigt sich auch die Anordnung von Schlitzen od.gl., wie sie zur Aufnahme einer separate Feder erforderlich sind. Durch Wahl eines Materials mit einem entsprechenden Elastizitätsmodul zur Herstellung der Bügelleiste läßt sich auch eine erheblich längere Gebrauchsdauer der Mechanik erzielen, als dies bei den bekannten Lösungen in der Regel der Fall ist.The proposed measures make production unnecessary and the assembly of a separate spring, as with the previous solutions are required. It is also unnecessary the arrangement of slots or the like, as for receiving a separate spring are required. By choosing a material with a corresponding modulus of elasticity for producing the Ironing board can also have a significantly longer service life achieve the mechanics than with the known solutions in the Is usually the case.

Bei einer Verschlußmechanik gemäß dem Oberbegriff des Anspruches 2, wie sie z.B. aus der AT 391 657 B oder der AT 392 236 B bekannt ist, ergibt sich durch die kennzeichnenden Merkmale des Anspruches 2 der Vorteil einer besonders einfachen Konstruktion. Außerdem ergibt sich bei der vorgeschlagenen Ausbildung der Bügelleiste der Vorteil eines nur sehr geringen Verschnittes und damit eine sehr weitgehende Ausnutzung des Rohmaterials. So ist es durch die vorgeschlagenen Maßnahmen möglich auch im Bereich der Zunge beim rohen Blechzuschnitt für die Bügelleiste eine gerade, sich über die an die Zunge angrenzenden Bereiche der Bügelleiste fortsetzende Kante vorzusehen.In a locking mechanism according to the preamble of the claim 2, e.g. from AT 391 657 B or the AT 392 236 B is known, results from the characteristic Features of claim 2 the advantage of a particularly simple Construction. The proposed training also results the ironing board has the advantage of very little waste and thus a very extensive use of the raw material. So it is also possible through the proposed measures in the area of the tongue when cutting raw sheet metal for the ironing board one straight, over the areas adjacent to the tongue edge to be continued on the ironing board.

Grundsätzlich könnte aber auch vorgesehen sein, daß die Zunge einen Durchbruch einer Versteifungsrippe der Grundplatte durchsetzt und deren Steg untergreift.In principle, it could also be provided that the Tongue an opening of a stiffening rib of the base plate interspersed and reaches under its web.

Durch die Merkmale des Anspruches 3 ergibt sich der Vorteil, daß sich aufgrund der geometrischen Gegebenheiten der Abstand der Aufstandslinie der Zunge von der Schwenkachse beim Aufschwenken der Bügelleiste vergrößert und damit das durch die Zunge erzeugte Drehmoment weitgehend konstant bleibt, da sich mit abnehmender Federkraft der Abstand von der Schwenkachse vergrößert.The features of claim 3 give the advantage that due to the geometric conditions, the distance of the Contact line of the tongue from the swivel axis when swiveling the ironing board enlarged and thus the generated by the tongue Torque remains largely constant as it decreases Spring force increases the distance from the swivel axis.

Durch die Merkmale des Anspruches 4 wird eine örtliche Überbeanspruchung des Materials bei Ausbiegen der Zunge vermieden und dadurch eine lange Lebensdauer der Mechanik sichergestellt. A local overuse is caused by the features of claim 4 avoid the material when the tongue is bent out and this ensures a long service life of the mechanics.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 eine Draufsicht auf eine erfindungsgemäße Verschlußmechanik,
  • Fig. 2 eine Seitenansicht der Verschlußmechanik gemäß der Fig. 1.
  • Fig. 3 und 4 ein Detail in vergrößertem Maßstab bei geöffneten und geschlossenen Dornen und
  • Fig. 5 und 6 ein Schnitt durch die Lagerung der Bügelleiste in vergrößertem Maßstab bei geöffneten und geschlossenen Dornen.
    • The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 is a plan view of a locking mechanism according to the invention,
  • FIG. 2 shows a side view of the locking mechanism according to FIG. 1.
  • 3 and 4 a detail on an enlarged scale with open and closed thorns and
  • 5 and 6 a section through the mounting of the ironing board on an enlarged scale with open and closed thorns.

    • Die Verschlußmechanik weist eine Grundplatte 1 auf, die entlang ihrer längeren Kanten mit gegengleichen Ausformungen u.zw. einem Vorsprung 20 und einer gegengleichen Ausnehmung 21 versehen ist. Die Grundplatte 1 der Verschlußmechanik trägt deren feste Dorne 2. Weiters ist auf der Grundplatte 1 eine Bügelleiste 3 schwenkbar gehalten, in der die beweglichen Dorne 4 eingenietet sind.The locking mechanism has a base plate 1 which runs along their longer edges with opposing shapes etc. a projection 20 and an opposite recess 21 is. The base plate 1 of the locking mechanism carries its fixed Mandrels 2. Furthermore, there is a bracket 3 on the base plate 1 pivotally held, in which the movable mandrels 4 riveted are.

    Die Grundplatte 1 ist mit einer abgestuften Versteifungsrippe 5 versehen, die sich über den größten Teil der Grundplatte 1 erstreckt, aber den Bereich der Bohrungen 6', die zur Aufnahme von Nieten zur Befestigung der Verschlußmechanik in einem Ordner vorgesehen sind, frei hält. Dabei ist die Bügelleiste 3 zwischen der Versteifungsrippe 5 und einer weiteren Versteifungsrippe 5', die sich im Bereich des Vorsprunges 20 erstreckt, eingebettet.The base plate 1 is with a stepped stiffening rib 5 provided, which cover most of the base plate 1 extends, but the area of the holes 6 ', which for Inclusion of rivets for fastening the locking mechanism in a folder are provided, keep clear. Here is the ironing board 3 between the stiffening rib 5 and a further stiffening rib 5 ', which extends in the region of the projection 20, embedded.

    Wie insbesondere aus den Fig. 5 und 6 zu ersehen ist, weist die Bügelleiste 3 an ihrer der Versteifungsrippe 5' des Vorsprunges 20 zugekehrten Stirnseite Vorsprünge 6 auf, die an der der Bügelleiste 3 zugekehrten Stirnwand der Versteifungsrippe 5' angeordnete Durchbrüche 7 durchsetzen und den Steg der Versteifungsrippe 5' untergreifen. Dabei sind die Abmessungen der Durchbrüche 7 und der Vorsprünge 6 so bemessen, daß sich nur ein geringes Spiel zwischen diesen Teilen ergibt. Die Berührungslinie der Vorsprünge 6 mit der unteren Kante der oberen Begrenzung des Durchbruchs 7 bildet dabei angenähert eine Schwenkachse 18, um die die Bügelleiste 3 gegenüber der Grundplatte 1 schwenkbar ist.As can be seen in particular from FIGS. 5 and 6, points the bracket 3 on the stiffening rib 5 'of the projection 20 facing end projections 6 on which the Strap 3 facing end wall of the stiffening rib 5 'arranged Make openings 7 and the web of the stiffening rib 5 'reach under. Here are the dimensions of the openings 7 and the projections 6 so that there is only a small Game between these parts results. The line of contact the projections 6 with the lower edge of the upper limit of the Breakthrough 7 approximately forms a pivot axis 18 which the bracket 3 is pivotable relative to the base plate 1.

    Für die Halterung der Bügelleiste 3, die gleichzeitig die Verbindung der beiden beweglichen Dorne 4 darstellt, sind aus der Grundplatte 1 Lappen 8 ausgestanzt, bzw. nach oben ausgebogen. Diese Lappen 8 durchsetzen Durchbrüche 9 der Bügelleiste 3, wodurch sich eine schwenkbare Halterung derselben auf der Grundplatte 1 ergibt und ein Lösen der Bügelleiste 3 von der Grundplatte 1 nur durch Abheben der Bügelleiste 3 von den Lappen 8 der Grundplatte 1 und gleichzeitigem Herausziehen der Vorsprünge 6 aus den Durchbrüchen 7 der Versteifungsrippe 5' möglich ist.For the bracket of the bracket 3, which at the same time the Connection of the two movable mandrels 4 are from the Base plate 1 tab 8 punched out or bent upwards. These flaps 8 pass through openings 9 of the bracket 3, whereby there is a pivotable holder of the same on the base plate 1 results and a release of the bracket 3 from the base plate 1 only by lifting the ironing board 3 off the tab 8 Base plate 1 and at the same time pulling out the projections 6 from the openings 7 of the stiffening rib 5 'is possible.

    Die Bügelleiste 3 weist ebenfalls eine Versteifungsrippe 10 auf, deren Stegbereich von den beweglichen Dornen 4 durchsetze ist. Dadurch wird neben einer Aussteifung der Bügelleiste auch Platz für die Ausbildung der Nietköpfe der Dorne 4 an der Unterseite der Bügelleiste 3 geschaffen. Gleiches gilt auch bezüglich der festen Dorne 2, die ebenfalls im Bereich der Versteifungsrippe 5 in der Grundplatte 1 gehalten und mittels einer Nietung mit dieser verbunden sind.The bracket 3 also has a stiffening rib 10 on, the web area penetrate by the movable mandrels 4 is. As a result, in addition to stiffening the ironing board, too Space for the formation of the rivet heads of the mandrels 4 on the underside the ironing board 3 created. The same also applies to the fixed mandrels 2, which are also in the area of the stiffening rib 5 held in the base plate 1 and by means of a rivet associated with this.

    Aus der Grundplatte 1 ist in üblicher Weise ein Haltelappen 11 ausgestanzt und aufgebogen, der zur Aufnahme der Lagerung eines Schließhebels 12 dient, der mit einer Rolle 13 an der erhabenen Versteifungsrippe 10 der Bügelleiste 3 anliegt und diese in der Schließstellung der Verschlußmechanik entgegen einer Vorspannkraft hält, die die Bügelleiste in eine der offenen Stellung der Dorne 2, 4 entsprechende Stellung drängt.From the base plate 1 is a retaining tab in the usual way 11 punched out and bent open to accommodate the storage a locking lever 12 is used, which with a roller 13 on the raised Stiffening rib 10 of the bracket 3 rests and this in the closed position of the locking mechanism against a biasing force which holds the ironing board in one of the open positions the mandrels 2, 4 push the corresponding position.

    Der Schließhebel 12 ist in üblicher Weise als Winkelhebel ausgebildet, der im Verbindungsbereich seiner beiden Schenkel an einer im Haltelappen 11 gehaltenen Buchse 14 drehbar gehalten ist. Die Rolle 13 ist an einem im Bereich des freien Endes des kleineren Schenkels gehaltenen Achse 15 drehbar befestigt.The locking lever 12 is in the usual way as an angle lever formed in the connecting area of his two legs a socket 14 held in the holding tab 11 is rotatably held is. The roller 13 is in the region of the free end of the smaller leg held axis 15 rotatably attached.

    Wie aus den Fig. 5 und 6 zu ersehen ist, sind die Durchbrüche 9 der Bügelleiste 3 im Bereich der Aufwölbung der Versteifungsrippe 10 angeordnet, wobei jedoch der zwischen der Stirnseite und dem Durchbruch 9 verbleibende Bereich nach unten eingeprägt ist, wodurch sich eine im wesentlichen flächige Anlage an dem Lappen 8 ergibt, zumindest in der geschlossenen Lage der Dorne 2, 4 (Fig. 6).As can be seen from FIGS. 5 and 6, the breakthroughs are 9 of the bracket 3 in the area of the bulge of the stiffening rib 10 arranged, however, between the front and the opening 9 remaining area stamped down is, which is an essentially flat system the tab 8 results, at least in the closed position of the Mandrels 2, 4 (Fig. 6).

    Die Vorsprünge 6 weisen eine geringere Dicke als die übrigen Bereiche der Bügelleiste auf und sind zweckmäßigerweise durch Prägen, bzw. Kaltumformung angeformt, sodaß dies Vorsprünge 6 keinen Verschnitt bei der Herstellung der einzelnen Blechteile bedingen.The projections 6 have a smaller thickness than the rest Areas of the ironing board and are expediently through Embossing or cold forming, so that this protrusions 6 no waste in the production of the individual sheet metal parts require.

    Wie aus der Fig. 1 zu ersehen ist, weist die Bügelleiste 3 in deren mittlerem Bereich eine von zwei Einschnitten 16 begrenzte Zunge 17 auf. Dabei sind die Einschnitte 16 an der der Versteifungsrippe 5' des Vorsprunges 20 der Grundplatte 1 zugekehrten Stirnseite der Bügelleiste 3 randoffen ausgebildet.As can be seen from FIG. 1, the ironing bar 3 in the middle area one of two incisions 16 delimited Tongue 17 on. The incisions 16 on the Stiffening rib 5 'of the projection 20 of the base plate 1 facing Front side of the ironing bar 3 is designed with the edge open.

    Wie aus den Fig. 3 und 4 zu ersehen ist, ist die Zunge 17 entlang einer ungebrochenen bogenförmigen Linie, die tangential in den Stegbereich der Versteifungsrippe 10 übergeht, nach unten ausgebogen. Dadurch steht die Zunge 17 mit ihrem freien Endbereich auf der Grundplatte 1 auf, wobei die Zunge 17 unter die durch die unteren Kanten der Versteifungsrippe 10 bestimmte Aufstandsebene ihres übrigen Bereiches ragt.As can be seen from FIGS. 3 and 4, the tongue is 17th along an unbroken arcuate line that is tangential merges into the web area of the stiffening rib 10, downwards bent. As a result, the tongue 17 stands with its free end region on the base plate 1, the tongue 17 under the through the lower edges of the stiffening rib 10 determined contact plane of their remaining area protrudes.

    Wie deutlich aus einem Vergleich der Fig. 3 und 4 zu ersehen ist, verändert sich beim Aufschwenken der Bügelleiste 3, d.h. beim Übergang von der geschlossenen Lage (Fig. 4) der Dorne 2, 4 in deren geöffnete Lage (Fig. 3) der Abstand a zwischen der Aufstandslinie der Zunge 17 auf der Grundplatte 1 und der Schwenkachse 18 der Bügelleiste 3. Da dieser Abstand a in der geöffneten Stellung (Fig. 3) der Dorne 2, 4 größer, als in deren geschlossener Stellung (Fig. 4) ist, bleibt das durch die federnde Zunge 17 ausgeübte Drehmoment weitgehend konstant, obwohl die durch die Zunge 17 ausgeübte Kraft in der geöffneten Stellung der Dorne 2, 4 aufgrund der geringeren Auslenkung von deren neutraler Stellung kleiner ist.As can clearly be seen from a comparison of FIGS. 3 and 4, changes when the bracket 3 is pivoted open, that is to say during the transition from the closed position (FIG. 4) of the mandrels 2, 4 to their open position (FIG. 3) Distance a between the contact line of the tongue 17 on the base plate 1 and the pivot axis 18 of the ironing bar 3. Since this distance a in the open position (FIG. 3) of the mandrels 2, 4 is greater than in their closed position (FIG. 4) is, the torque exerted by the resilient tongue 17 remains largely constant, although the force exerted by the tongue 17 in the open position of the mandrels 2, 4 is smaller due to the smaller deflection from their neutral position.

    Bedingt ist dieser Effekt durch den Umstand, daß die Schwenkachse 18 in einem vertikalen Normalabstand oberhalb der Aufstandsebene der Zunge 17 auf der Grundplatte 1 liegt.This effect is due to the fact that the Swivel axis 18 at a vertical normal distance above the Contact level of the tongue 17 lies on the base plate 1.

    Durch die Ausbildung der Zunge 17 ergibt sich eine ausreichende Vorspannung für die Bügelleiste 3 gegen deren der offenen Stellung der Dorne 2, 4 entsprechende Stellung, ohne daß eine separate Feder erforderlich ist.The formation of the tongue 17 results in an adequate Bias for the bracket 3 against the open Position of the mandrels 2, 4 corresponding position, without a separate spring is required.
