Definitions
- the invention relates to a sewing for particular textile materials, such as garments, certain knob with at least two from the top to the bottom of the knob through openings for the suture thread, between which formed an open towards the top receiving channel for the suture in the button is like this example CH-A 262 869 is known.
- Buttons are machine-sewn in the textile industry, wherein the button is anchored by means of Knopfannähmaschine on the underside of the textile material only by a Kettstichverschlingung. After sewing, the sewing thread is tightened and torn off by lifting the button clip in the knot. It may happen that the end thread protrudes due to insufficient knotting the warp stitch or by stitching outward. Pulling on this protruding thread end, the Kettstichverschlingung dissolves slightly again, until the button is released and falls off.
- buttons There has been no lack of attempts to develop methods and sewing threads, with the help sewed buttons to be protected against falling. But these known methods set usually preceded by the buttons are sewn to form a button handle, which is carried out only in certain cases.
- a Stielumwicklungsfaden is used from an elastomeric plastic, which is deducted after wrapping the stems forming filament bundle of the button stem in approximately vertical direction to the axis with an increased tensile strength beyond its yield point before being severed at the button handle. Due to the stretching of the wrapping thread occurring in this case reduces its diameter, so that the thread end can penetrate between previously defined turns of the stem wrap, there embeds and firmly clamped after entering the severing of the tensile force during cutting.
- a known button ( CH 262 869 ) of the type indicated above is provided to avoid chafing of a twine there called button stem on the rough edges of a buttonhole that a button above the disc projecting eye covers and sewn by a buttonhole button the thread on all sides against the buttonhole edges. Measures to avoid unintentional loosening and dropping of the button due to a protruding thread end are not met in this known button.
- the object of the present invention is to design a button so that no free end of the thread projects beyond the sewing process.
- the thread bundle formed during the sewing of the button fills the receiving channel in such a way that the thread end embeds firmly in the thread bundle in the receiving channel.
- the problem underlying the invention is achieved exclusively by a special design of the button.
- the receiving channel according to claim 2 has a cross section formed from two differently shaped regions, consisting of a funnel-shaped widening to the top insertion area for the sewing thread and a receiving area for the formed from the suture, the button fastened thread bundle.
- the funnel-shaped insertion area ensures that the sewing thread is guided into the receiving area.
- the receiving area according to claim 3 has a substantially circular cross-section, which is connected via a passage gap for the sewing thread with the lead-in area.
- the thread bundle created during sewing experiences a correspondingly structured cross-sectional shape in the receiving region of the receiving channel.
- the relatively narrow passage gap ensures that the receiving area is undercut and the Securely holds the bundle of fibers including the embedded thread end.
- the insertion region of the receiving channel is preferably limited to optimize its thread guiding properties according to claim 4 of two mutually arranged at an acute angle guide surfaces which form the passage gap at the point of their smallest mutual distance with parallel aligned edges.
- the guide surfaces converging towards each other in the direction of the receiving space guide the sewing thread during the sewing process to the passage gap and through it into the receiving region.
- the passage gap expediently has a clear width, which corresponds approximately to the simple to about three times the Nähfaden tomessers, as stated in claim 5.
- the gap should correspond to a needle to be sewn on knob about three times the thread diameter, while not sewn on the handle buttons, the gap should correspond approximately to the thread diameter.
- the receiving channel extends in a straight line between the two lead-through openings, as indicated in claim 6.
- the receiving channel extends with a plurality of changes in direction in a zig-zag course between the two lead-through openings. It is advantageous if according to claim 8, the lead-in area of the receiving channel of the number of changes in direction accordingly is bounded by pairs of opposing triangular guide surfaces, each of the guide surface pair widens funnel-shaped towards the top, and when the receiving area for the thread bundle formed from the suture from pairs oppositely arranged parallel wall surfaces, the upper edge of each with the base edge of the associated triangular Guide surface coincides.
- the knob is made of an elastomeric material having a Shore hardness between about 60 and about 70, wherein starting from the bottom between the two passage openings in the region of the receiving channel and before this endend a wall thickness-reducing cavity is formed , This cavity allows due to the suture tension during sewing an elastic deformation of the central portion of the rubber-elastic button, whereby the clamping and holding action on the thread end in the receiving channel is still increased, in particular it may be a constriction of the passage gap.
- FIGS. 1 to 5 a first embodiment and the FIGS. 14 to 18 relate to a second embodiment
- FIGS. 6 to 9 on the one hand and the FIGS. 10 to 13 on the other hand represent variants of the first embodiment.

Abstract
Description
Die Erfindung bezieht sich auf einen zum Annähen an insbesondere textile Materialien, wie Kleidungsstücke, bestimmter Knopf mit mindestens zwei von der Oberseite bis zur Unterseite des Knopfes durchgehenden Durchführungsöffnungen für den Nähfaden, zwischen denen ein zur Oberseite hin offener Aufnahmekanal für den Nähfaden in den Knopf eingeformt ist, wie dieser beispielweise aus
Knöpfe werden in der Textilindustrie maschinell angenäht, wobei der Knopf mittels der Knopfannähmaschine auf der Unterseite des textilen Materials lediglich durch eine Kettstichverschlingung verankert wird. Nach dem Annähvorgang wird der Nähfaden durch Anheben der Knopfklammer in der Verknotung fest angezogen und abgerissen. Dabei kann es vorkommen, daß der Endfaden durch nicht genügende Verknotung des Kettstichs oder durch Fehlstichbildung nach außen vorsteht. Zieht man an diesem hervorstehenden Fadenende, löst sich die Kettstichverschlingung leicht wieder auf, bis sich der Knopf löst und abfällt. Ein zusätzliches oder nachträgliches Umschlingen des beim Annähen zwischen der Knopfunterseite und der Oberseite des textilen Materials aus dem Nähfaden gebildeten Fadenbündels erfolgt ebenfalls unter Verwendung des Kettstichs und kann das geschilderte Problem nur unzulänglich beseitigen, je nachdem, ob die Umschlingung und Verknotung des Halses enger oder lockerer erfolgt.Buttons are machine-sewn in the textile industry, wherein the button is anchored by means of Knopfannähmaschine on the underside of the textile material only by a Kettstichverschlingung. After sewing, the sewing thread is tightened and torn off by lifting the button clip in the knot. It may happen that the end thread protrudes due to insufficient knotting the warp stitch or by stitching outward. Pulling on this protruding thread end, the Kettstichverschlingung dissolves slightly again, until the button is released and falls off. An additional or subsequent wrapping of the thread bundle formed during sewing between the button bottom and the top of the textile material from the suture is also done using the Kettstichs and can only inadequately eliminate the problem described, depending on whether the wrap and knot the neck close or looser he follows.
Es hat nicht an Versuchen gefehlt, Verfahren und Nähfäden zu entwickeln, mit deren Hilfe angenähte Knöpfe gegen Abfallen gesichert werden sollen. Diese bekannten Verfahren setzen aber in der Regel voraus, daß die Knöpfe unter Ausbildung eines Knopfstiels angenäht werden, was allerdings nur in bestimmten Fällen durchgeführt wird.There has been no lack of attempts to develop methods and sewing threads, with the help sewed buttons to be protected against falling. But these known methods set usually preceded by the buttons are sewn to form a button handle, which is carried out only in certain cases.
So ist beispielsweise schon vorgeschlagen worden (
Bei einem weiteren bekannten Verfahren (
Allen bekannten Verfahren ist gemeinsam, daß die Lösung des geschilderten Problems durch besondere verfahrenstechnische Maßnahmen und/oder durch spezielle Nähfäden angestrebt wird.All known methods have in common that the solution of the problem described by special procedural measures and / or by special sewing threads is sought.
Bei einem bekannten Knopf (
Der vorliegenden Erfindung liegt dagegen die Aufgabe zugrunde, einen Knopf so auszubilden, daß nach dem Annähvorgang kein freies Fadenende vorsteht.On the other hand, the object of the present invention is to design a button so that no free end of the thread projects beyond the sewing process.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und Ausführungsformen gehen aus den Unteransprüchen hervor und sind nachfolgend ebenfalls näher beschrieben.This object is achieved by the features specified in
Ausgehend von dem eingangs angegebenen Knopf ist entsprechend dem Anspruch 1 vorgesehen, daß der zwischen den beiden Durchführungsöffnungen in den Knopf eingeformte, zur Oberseite hin offene Aufnahmekanal für den Nähfaden für das Festhalten des Fadenendes ausgebildet ist. Nach der Grundidee der vorliegenden Erfindung füllt das beim Annähen des Knopfes gebildete Fadenbündel den Aufnahmekanal derart, daß sich das Fadenende festverklemmend in das Fadenbündel im Aufnahmekanal einbettet. Hierzu bedarf es weder eines besonderen Knopfannähverfahrens noch eines besonderen Nähfadens. Es können vielmehr die üblichen Knopfannähmaschinen und die dafür üblichen Nähfäden verwendet werden. Selbstverständlich können derartig ausgebildete Knöpfe auch von Hand angenäht werden. Die der Erfindung zugrundeliegende Aufgabe wird ausschließlich durch eine besondere Gestaltung des Knopfes gelöst.Based on the above-mentioned button is provided according to the
Im Verfolg des Erfindungsgedankens weist der Aufnahmekanal gemäß Anspruch 2 einen aus zwei unterschiedlich geformten Bereichen gebildeten Querschnitt auf, bestehend aus einem sich zur Oberseite hin trichterförmig erweiternden Einführungsbereich für den Nähfaden und einem Aufnahmebereich für das aus dem Nähfaden gebildete, den Knopf befestigende Fadenbündel. Der trichterförmige Einführungsbereich sorgt dafür, daß der Nähfaden in den Aufnahmebereich geleitet wird. Diese Besonderheit besitzen alle hier beschriebenen Ausführungsformen und Varianten des Knopfes.In pursuit of the inventive concept, the receiving channel according to
Vorzugsweise weist der Aufnahmebereich entsprechend Anspruch 3 einen im wesentlichen kreisflächenförmigen Querschnitt auf, der über einen Durchtrittsspalt für den Nähfaden mit dem Einführungsbereich verbunden ist. Auf diese Weise erfährt das beim Annähen entstehende Fadenbündel im Aufnahmebereich des Aufnahmekanals eine entsprechend strukturierte Querschnittsgestalt. Dabei sorgt der verhältnismäßig enge Durchtrittsspalt dafür, daß der Aufnahmebereich hinterschnitten ist und das Fadenbündel einschließlich des eingebetteten Fadenendes sicher festhält.Preferably, the receiving area according to
Der Einführungsbereich des Aufnahmekanals ist zur Optimierung seiner Fadenleiteigenschaften vorzugsweise entsprechend Anspruch 4 von zwei zueinander in einem spitzen Winkel angeordneten Führungsflächen begrenzt, die an der Stelle ihres geringsten gegenseitigen Abstandes mit parallel zueinander ausgerichteten Kanten den Durchtrittsspalt bilden. Die auf diese Weise zueinander in Richtung des Aufnahmeraums konvergierend angeordneten Führungsflächen leiten den Nähfaden beim Annähvorgang zu dem Durchtrittsspalt und durch diesen hindurch in den Aufnahmebereich.The insertion region of the receiving channel is preferably limited to optimize its thread guiding properties according to claim 4 of two mutually arranged at an acute angle guide surfaces which form the passage gap at the point of their smallest mutual distance with parallel aligned edges. The guide surfaces converging towards each other in the direction of the receiving space guide the sewing thread during the sewing process to the passage gap and through it into the receiving region.
Der Durchtrittsspalt besitzt zweckmäßig eine lichte Weite, die etwa dem Einfachen bis etwa dem Dreifachen des Nähfadendurchmessers entspricht, wie in Anspruch 5 angegeben ist. Hierbei sollte das Spaltmaß bei einem auf Stiel zu nähenden Knopf etwa dem dreifachen Fadendurchmesser entsprechen, während bei nicht auf Stiel genähten Knöpfen das Spaltmaß etwa dem Fadendurchmesser entsprechen sollte.The passage gap expediently has a clear width, which corresponds approximately to the simple to about three times the Nähfadendurchmessers, as stated in
Für viele Anwendungsbereiche ist es ausreichend und zweckmäßig, wenn der Aufnahmekanal geradlinig zwischen den beiden Durchführungsöffnungen verläuft, wie das im Anspruch 6 angegeben ist.For many applications, it is sufficient and expedient if the receiving channel extends in a straight line between the two lead-through openings, as indicated in
Eine zusätzliche Verklammerung des beim Annähen gebildeten Fadenbündels einschließlich des Fadenendes ergibt sich, wenn sich entsprechend Anspruch 7 der Aufnahmekanal mit mehreren Richtungsänderungen in einem Zick-Zack-Verlauf zwischen den beiden Durchführungsöffnungen erstreckt. Hierbei ist es von Vorteil, wenn gemäß Anspruch 8 der Einführungsbereich des Aufnahmekanals der Anzahl der Richtungsänderungen entsprechend durch paarweise gegenüberliegende dreieckige Führungsflächen begrenzt ist, von denen jedes Führungsflächenpaar sich zur Oberseite hin trichterförmig erweitert, und wenn der Aufnahmebereich für das aus dem Nähfaden gebildete Fadenbündel von paarweise gegenüberliegend parallel zueinander angeordneten Wandflächen gebildet ist, deren obere Kante jeweils mit der Basiskante der zugehörigen dreieckigen Führungsfläche zusammenfällt.An additional clamping of the filament bundle formed during sewing, including the thread end results when, according to
In einer besonderen im Anspruch 9 angegebenen Ausführungsform ist der Knopf aus einem elastomeren Werkstoff mit einer Shore-Härte zwischen etwa 60 und etwa 70 hergestellt, wobei ausgehend von der Unterseite zwischen den beiden Durchführungsöffnungen im Bereich des Aufnahmekanals und vor diesem endend ein wanddickenreduzierender Hohlraum eingeformt ist. Dieser Hohlraum ermöglicht infolge der Nähfadenspannung beim Annähvorgang eine elastische Deformation des zentralen Bereichs des gummielastischen Knopfes, wodurch die Klemm- und Halteeinwirkung auf das Fadenende im Aufnahmekanal noch vergrößert wird, insbesondere kommt es ggf. zu einer Verengung des Durchtrittsspalts.In a particular embodiment specified in

In den Zeichnungen sind zwei Ausführungsformen eines erfindungsgemäßen Knopfes dargestellt, von denen die
Der daraus ersichtliche Knopf besitzt zwei von seiner Oberseite 1 bis zu seiner Unterseite 2 durchgehende, im Querschnitt kreisflächenförmige Durchführungsöffnungen 3 für den Nähfaden (letzterer ist in allen Figuren nicht dargestellt). Die Oberseite 1 des Knopfes ist in eine äußere ebene Kreisringfläche 4 und eine aus der Ebene der Kreisringfläche 4 nach oben vorspringende kuppelförmige Zentralerhebung 5 gegliedert. Auf seiner Unterseite 2 ist der Knopf mit einer zur Kreisringfläche 4 planparallelen ebenen Zentralfläche 6 versehen, an die sich außen ein Randbereich 7 anschließt, der den abgeschrägten/abgerundeten Übergang zu der Kreisringfläche 4 an der Oberseite 1 herstellt.The apparent therefrom button has two from its top 1 to its
Zwischen den beiden Durchführungsöffnungen 3 unterbrechungslos durchgehend befindet sich ein die beiden Durchführungsöffnungen 3 miteinander verbindender Aufnahmekanal 8, der durch die kuppelförmige Zentralerhebung 5 hindurchgeführt ist. Der Aufnahmekanal 8 weist einen aus zwei unterschiedlich geformten Bereichen gebildeten Querschnitt auf, wie am besten aus
Der Einführungsbereich 9 ist von zwei zueinander in einem spitzen Winkel angeordneten Führungsflächen 11 begrenzt, welche beim Knopfannähvorgang den Nähfaden zu dem und in den Aufnahmebereich 10 führen. Der Aufnahmebereich 10 weist einen im wesentlichen kreisflächenförmigen Querschnitt auf und ist mit dem Einführungsbereich 9 über einen Durchtrittsspalt 12 für den Nähfaden verbunden. Die Führungsflächen 11 bilden an der Stelle ihres geringsten gegenseitigen Abstandes mit parallel zueinander ausgerichteten Kanten 13 den Durchtrittsspalt 12. Dessen lichte Weite kann etwa dem Einfachen bis etwa dem Dreifachen des Nähfadendurchmessers entsprechen, je nach Knopfausbildung und Knopfanbringungsart. Wie insbesondere aus den Figuren 1 und 2 ersichtlich ist, verläuft der Aufnahmekanal 8 zwischen den beiden Durchführungsöffnungen 3 geradlinig.The
Falls der bisher beschriebene Knopf aus einem elastomeren Werkstoff, beispielsweise aus Gummi mit einer Shore-Härte zwischen etwa 60 und etwa 70, hergestellt ist, d.h. eine bestimmte elastische Verformbarkeit aufweist, ist es sinnvoll, ausgehend von seiner Unterseite 2 in der Mitte der Zentralfläche 6, zwischen den beiden Durchführungsöffnungen 3 und im Bereich des Aufnahmekanals 8 und vor diesem endend einen Hohlraum 14 einzuformen. Dieser Hohlraum 14 reduziert die Wanddicke zwischen den beiden Durchführungsöffnungen 3 und auch zu dem Aufnahmekanal 8 hin derart, daß beim Knopfannähvorgang infolge der von der Nähfadenspannung übertragenen Zugkraft im Bereich der verringerten Wanddicken elastische Verformungen auftreten, welche das Fadenbündel und damit auch das Fadenende zusätzlich im Aufnahmebereich 10 des Aufnahmekanals 8 einklemmen. Hierbei werden die Kanten 13 des Durchtrittsspalts 12 im Sinne einer Spaltweitenverringerung aufeinander zu bewegt.If the previously described button is made of an elastomeric material, for example rubber having a Shore hardness between about 60 and about 70, i. E. has a certain elastic deformability, it makes sense, starting from its bottom 2 in the middle of the

Bei dieser Variante ist an der Oberseite 1 des Knopfes eine vertieft liegende ebene Kreisfläche 15 vorgesehen, die von einem Ringvorsprung 16 umgeben ist. Die Unterseite 2 ist insgesamt etwa nach Art eines flachen Kugelabschnitts geformt. Der Einführungsbereich 9 des Aufnahmekanals 8 beginnt mit seinen Führungsflächen 11 an der Kreisfläche 15.

Auch bei dieser Variante ist an der Oberseite 1 des Knopfes eine vertieft liegende ebene Kreisfläche 15 vorhanden, die von einem Ringvorsprung 16 umgeben ist. Die Unterseite 2 ist in ihrem äußeren Bereich ebenfalls kugelabschnittförmig gestaltet, besitzt jedoch einen aus der kugelabschnittförmigen Fläche vorstehenden Zentralzapfen 18. Der bei dieser Variante vergleichsweise längere Einführungsbereich 9 des Aufnahmekanals 8 beginnt mit seinen Führungsflächen 11 an der Kreisfläche 15 und endet mit seinen den Durchtrittsspalt 12 definierenden Kanten 13 etwa dort, wo der Zentralzapfen beginnt. Die Durchtrittsöffnungen 3 beginnen an der Kreisfläche 15 und enden an der kugelabschnittförmigen Fläche an der Unterseite 2.Also in this variant, a recessed flat
Der Aufnahmebereich 10 des Aufnahmekanals 8 befindet sich als Querausnehmung ausschließlich im Zentralzapfen 18, der von dem Aufnahmebereich 10 vollständig durchsetzt wird, so daß dieser nach beiden Seiten hin freiliegt.

- Button according to claim 1, characterised in that the receiver channel (8, 8') has a cross-section formed from two areas (9, 9'; 10, 10') of different shapes, comprising an insertion area (9, 9') for the sewing thread expanding funnel-like towards the top (1), and a receiving area (10, 10') for the thread bundle formed from the sewing thread and fixing the button.
- Button according to claim 2, characterised in that the receiving area (10) has a substantially circular cross-section which is connected with the insertion area (9) via a passage gap (12) for the sewing thread.
- Button according to claims 2 and 3, characterised in that the insertion area (9) is limited by two guide surfaces (11) arranged at an acute angle to each other, which at the point of their smallest mutual distance form the passage gap (12) with edges (13) aligned parallel to each other.
- Button according to claim 3 or 4, characterised in that the passage gap (12) has a clear width which corresponds to around once to around three times the diameter of the sewing thread.
- Button according to one of claims 1 to 5, characterised in that the receiver channel (8) runs in a straight line between the two passage openings (3).
- Button according to one of claims 1 or 2, characterised in that the receiver channel (8') extends with several direction changes in a zigzag pattern between the two passage openings (3).
- Button according to claims 2 and 7, characterised in that the insertion area (9') of the receiver channel (8') is limited, depending on number of direction changes, by triangular guide surfaces (11') lying opposite each other in pairs, every guide surface pair of which expands funnel-like towards the top (1), and that the receiver area (10') for the thread bundle formed by the sewing thread is formed from pairs of opposing wall surfaces (19) arranged parallel to each other, the upper edges (20) of which each coincide with the base edge of the associated triangular guide surface (11').
- Button according to any of the preceding claims, characterised in that it is made from an elastomer material with a Shore hardness between around 60 and around 70, and that starting from the underside (2), between the two passage openings (3) in the area of the receiver channel (8, 8') and ending in front of this, is formed a cavity (14) which reduces the wall thickness.
