Eine C-förmig ausgestaltete Nähmaschine 1 weist einen oberen Arm 2, eine gehäuseartige Grundplatte 3 und einen den Arm 2 und die Grundplatte 3 verbindenden Ständer 4 auf. Im Arm 2 ist eine nur angedeutete Armwelle 5 angeordnet, die von einem ebenfalls nur angedeuteten Antriebsmotor 6 antreibar ist. Von der Armwelle 5 wird in üblicher Weise eine Nadelstange 7 mit einer Nadel 8 auf- und abgehend angetrieben.A C-shaped configured sewing machine 1 has an upper arm 2, a housing-like base plate 3 and a stand 2 connecting the arm 2 and the base plate 3. In the arm 2 an only indicated arm shaft 5 is arranged, which is driven by a drive motor 6 also indicated only. Of the arm shaft 5, a needle bar 7 is driven up and down with a needle 8 in the usual way.

Die Nähmaschine 1 ist auf einer Auflageplatte 9 eines Tisches 10 angeordnet, der über ein Gestell 11 auf dem Boden 12 abgestützt ist. Am Gestell 11 ist eine Steuerung 13 für die Nähmaschine 1 angebracht, die über ein Gestänge 14 mit einem Fuß-Bedienschalter 15 verbunden ist. Der Fuß-Bedienschalter 15 kann von der nicht dargestellten Bedienungsperson von der Bedienungsseite 16 her betätigt werden.The sewing machine 1 is arranged on a support plate 9 of a table 10, which is supported on the base 12 via a frame 11. On the frame 11 a controller 13 is attached to the sewing machine 1, which is connected via a linkage 14 with a foot control switch 15. The foot control switch 15 can be operated by the operator, not shown, from the operating side 16 ago.

Die Nähmaschine 1 ruht mit ihrer Grundplatte 3 auf einer Lagerplatte 17. Sie ist mit dieser über ein Scharnier 18 verbunden, dessen stangenartige Lagerachse 19 etwa parallel zur Armwelle 5 verläuft, also in Längsrichtung der Nähmaschine 1. Die Lagerachse 19 befindet sich horizontal benachbart zur Längs-Rückseite 20 der Nähmaschine 1 und benachbart zur Unterseite 21 der Grundplatte 3, mit der sie auf der Lagerplatte 17 aufliegt. Das Scharnier 18 wird durch zwei mit der Lagerplatte 17 fest verbundene Lagerböcke 22 und die in diesen gelagerte Lagerachse 19 gebildet. Die Nähmaschine 1 kann um die Lagerachse 19 des Scharniers 18 mit der Längs-Rückseite 20 in Richtung auf die Auflageplatte 9 gekippt werden.The sewing machine 1 rests with its base plate 3 on a bearing plate 17. It is connected thereto by a hinge 18, the rod-like bearing axis 19 extends approximately parallel to the arm shaft 5, ie in the longitudinal direction of the sewing machine 1. The bearing axis 19 is located horizontally adjacent to the longitudinal Rear side 20 of the sewing machine 1 and adjacent to the bottom 21 of the base plate 3, with which it rests on the bearing plate 17. The hinge 18 is formed by two fixedly connected to the bearing plate 17 bearing blocks 22 and mounted in these bearing axis 19. The sewing machine 1 can be tilted about the bearing axis 19 of the hinge 18 with the longitudinal rear side 20 in the direction of the support plate 9.

Die Lagerplatte 17 ist an ihrer Unterseite mit einem aus Filz bestehenden Schall- und Schwingungs-Dämpfungs-Belag 23 versehen, mit dem sie also auf der Auflageplatte 9 aufliegt. Die Lagerplatte 17 ist mit der Nähmaschine 1 auf der Auflageplatte 9 verschiebbar. Die Lagerplatte 17 ist mittels eines Schwenklagers 24 gegenüber der Auflageplatte 9 um eine vertikale Achse 25, also um eine senkrecht zur Auflageplatte 9 verlaufende Achse 25, schwenkbar gelagert. Das Schwenklager 24 besteht im Wesentlichen aus einem rohrförmigen hohlen Lagerzapfen 26, der mit der Lagerplatte 17 durch einen an ihm ausgebildeten Ringflansch 27 und eine aufgeschraubte Mutter 27a fest verbunden und in einer Lageröffnung 28 der Auflageplatte 9 gelagert ist. Der Lagerzapfen 26 ist an der Unterseite 29 der Auflageplatte 9 nicht gesichert, wird also nur von oben in die Lageröffnung 28 eingesteckt. Die Lagerplatte 17 mit Nähmaschine 1 wird auf der Auflageplatte 9 also nur durch ihr Gewicht gesichert.The bearing plate 17 is provided on its underside with a consisting of felt sound and vibration damping coating 23, with which it rests on the support plate 9. The bearing plate 17 is displaceable with the sewing machine 1 on the support plate 9. The bearing plate 17 is pivotally mounted by means of a pivot bearing 24 relative to the support plate 9 about a vertical axis 25, that is about a perpendicular to the support plate 9 extending axis 25. The pivot bearing 24 consists essentially of a tubular hollow bearing pin 26 which is fixedly connected to the bearing plate 17 by an annular flange 27 formed on it and a nut 27 a screwed on and mounted in a bearing opening 28 of the support plate 9. The bearing pin 26 is not secured to the underside 29 of the support plate 9, so it is only inserted from above into the bearing opening 28. The bearing plate 17 with sewing machine 1 is thus secured on the support plate 9 only by its weight.

Es ist aber auch ohne Weiteres möglich, am unteren Ende des Lagerzapfens 26, also unterhalb der Unterseite 29 der Auflageplatte 9, einen Sicherungsring vorzusehen, sodass insbesondere für den Transport der Vorrichtung in Richtung der Achse 25 eine formschlüssige Verbindung zwischen der Nähmaschine 1 und dem Tisch 10 gegeben ist.But it is also readily possible, at the lower end of the journal 26, so below the bottom 29 of the support plate 9 to provide a locking ring, so in particular for the transport of the device in the direction of the axis 25, a positive connection between the sewing machine 1 and the table 10 is given.

Der Lagerzapfen 26 besteht aus Kunststoff und dient als verschleißgeschützte Durchführung für durch den Lagerzapfen 26 hindurchgeführte pneumatische und/oder elektrische Leitungen 30. Derartige Leitungen 30 verbinden die Steuerung 13 mit der Nähmaschine 1, in deren Grundplatte 3 sie münden.The bearing pin 26 is made of plastic and serves as a wear-protected passage for passed through the bearing pin 26 pneumatic and / or electrical lines 30. Such lines 30 connect the controller 13 to the sewing machine 1, in the base plate 3 they open.

Die Lagerplatte 17 kann mittels einer Arretier-Einrichtung 31 in zwei um einen rechten Winkel gegeneinander versetzten Arbeitsstellungen gegenüber der Auflageplatte 9 fixiert werden. Wie sich hierzu aus Fig. 3 ergibt, kann damit die Nähmaschine 1 in zwei Arbeitsstellungen relativ zur Bedienungsseite 16 hin fixiert werden, wobei in einer - in Fig. 3 ausgezogen dargestellten - ersten Arbeitsstellung ihre Längs-Vorderseite 32 der Bedienungsseite 16 zugewandt ist, während in einer - in Fig. 3 gestrichelt dargestellten - zweiten Arbeitsstellung die der Nadelstange 7 mit Nadel 8 benachbarte Stirnseite 33 der Nähmaschine 1 der Bedienungsseite 16 zugewandt ist. Die Arretier-Einrichtung 31 besteht im Wesentlichen aus einem Bolzen 34, der eine entsprechende Bohrung 35 in der Lagerplatte 17 durchsetzt und alternativ in eine von zwei in der Auflageplatte 9 ausgebildeten, den beiden geschilderten Arbeitsstellungen zugeordneten Öffnungen 36 in der Auflageplatte 9 einführbar ist. Der Bolzen 34 kann mit einem Gewinde versehen sein. Er weist an seiner Oberseite einen Griff-Kopf 37 auf.The bearing plate 17 can be fixed by means of a locking device 31 in two offset by a right angle to each other working positions relative to the support plate 9. How to do this Fig. 3 results, so that the sewing machine 1 can be fixed in two working positions relative to the operating side 16 back, in one - in Fig. 3 shown extended - first working position its longitudinal front side 32 of the operating side 16 faces, while in a - in Fig. 3 shown in phantom - second working position of the needle bar 7 with needle 8 adjacent end face 33 of the sewing machine 1 of the operating side 16 faces. The locking device 31 consists essentially of a bolt 34, which passes through a corresponding bore 35 in the bearing plate 17 and, alternatively, in one of two formed in the support plate 9, the two described working positions associated openings 36 in the support plate 9 is inserted. The bolt 34 may be threaded. He has on its upper side a handle head 37.

An der Längs-Vorderseite 32 ist am Arm 2 ein Bedienpult 38 um ein Schwenkgelenk 39 mit vertikaler Schwenkachse 40 angelenkt, das auf der der Nadelstange 7 zugewandten Seite des Bedienpultes 38 angeordnet ist.On the longitudinal front side 32 on the arm 2, a control panel 38 is articulated about a pivot joint 39 with vertical pivot axis 40, which is arranged on the needle bar 7 facing side of the control panel 38.

In den Figuren 5 und 6 sind die beiden Einsatzgebiete der Nähmaschine 1 dargestellt. In einem Nähgutteil 41 werden durch Stichgruppen gebildete Nahtbilder, beispielsweise Knopflöcher oder Riegel genäht, und zwar jeweils mehrere im Abstand voneinander.In the FIGS. 5 and 6 the two areas of application of the sewing machine 1 are shown. In a fabric part 41 formed by stitch groups seams, such as buttonholes or latches are sewn, in each case a plurality of spaced apart.

Bei der Anordnung der Nähmaschine 1 gemäß Fig. 5 werden in einer Reihe angeordnete Knopflöcher 42 nacheinander genäht, deren Längsrichtung parallel zur Bedienungsseite 16 und zur Kante 43 des Nähgutteils 41 verlaufen. Die Knopflöcher 42 liegen also mit ihrer Längsrichtung hintereinander auf einer Linie. Das Nähgutteil 41 wird beim Nähen jedes einzelnen Knopfloches 42 mittels eines Nähguthalters 44 auf der Grundplatte 3 gehalten und geführt. Der Nähguttransport erfolgt nach dem Nähen jedes Knopflochs 42 parallel zur Längs-Vorderseite 32 und parallel zur Bedienungsseite 16 in Nähgut-Transportrichtung 45. Die Längs-Vorderseite 32 der Nähmaschine 1 ist hierbei der Bedienungsseite 16 zugewandt. Das Bedienpult 38 ist an den Arm 2 angeklappt, sodass es von der Bedienungsseite 16 her einsehbar und bedienbar ist.In the arrangement of the sewing machine 1 according to Fig. 5 are sequentially sewn in a row buttonholes 42, the longitudinal direction parallel to the operating side 16 and the edge 43 of the workpiece 41. The buttonholes 42 thus lie with their longitudinal direction one behind the other on a line. The fabric part 41 is held and guided when sewing each individual button hole 42 by means of a fabric holder 44 on the base plate 3. The Nähguttransport takes place after sewing each buttonhole 42 parallel to the longitudinal front side 32 and parallel to the operating side 16 in the fabric transport direction 45. The longitudinal front side 32 of the sewing machine 1 in this case the operating side 16 faces. The control panel 38 is folded on the arm 2, so that it is visible from the operating side 16 ago and operated.

Bei der in Fig. 6 dargestellten Betriebsweise ist die Stirnseite 33 der Nähmaschine 1 der Bedienungsseite 16 zugewandt; die Nähmaschine 1 ist mitsamt der Lagerplatte 17 also um 90° gegenüber der in Fig. 5 dargestellten Arbeitsstellung verschwenkt und in dieser Arbeitsstellung mit der Auflageplatte 9 verriegelt. Im Nähgutteil 46 werden Knopflöcher 47 genäht, die quer zur Nähgut-Transportrichtung 49 also auch quer zur Kante 48 des Nähgutteils 46 verlaufen. Sie sind zwar auch in einer Reihe hintereinander angeordnet, verlaufen aber mit ihrer jeweiligen Längsrichtung quer zur Nähgut-Transportrichtung 49. Sie verlaufen aber auch mit ihrer jeweiligen Längsrichtung parallel zur Längs-Vorderseite 32 der Nähmaschine 1, d. h. der eigentliche Nähvorgang selber erfolgt relativ zur Nähmaschine 1 in gleicher Weise wie bei der Arbeitsweise nach Fig. 5. Damit in diesem Fall das Bedienpult 38 von der Bedienungsseite 16 her sichtbar und bedienbar ist, ist es in Richtung zur Nadelstange 7 hin in eine um 90° gegenüber Fig. 5 versetzte Position verschwenkt, in der es quer zur Längs-Vorderseite 32 von der Nähmaschine 1 absteht.At the in Fig. 6 shown operation, the end face 33 of the sewing machine 1 of the operating side 16 faces; the sewing machine 1 is thus together with the bearing plate 17 by 90 ° relative to the in Fig. 5 shown working position pivoted and in this working position with the support plate 9 locks. In the sewing material 46 buttonholes 47 are sewn, which thus extend transversely to the fabric transport direction 49 so also transversely to the edge 48 of the workpiece 46. Although they are also arranged in a row one behind the other, but extend with their respective longitudinal direction transverse to the fabric transport direction 49. However, they also run with their respective longitudinal direction parallel to the longitudinal front side 32 of the sewing machine 1, ie the actual sewing itself takes place relative to the sewing machine 1 in the same manner as in the operation after Fig. 5 , So that in this case the control panel 38 is visible and operable from the operating side 16 forth, it is in the direction of the needle bar 7 out in a 90 ° opposite Fig. 5 displaced position pivoted in which it projects transversely to the longitudinal front side 32 of the sewing machine 1.

Da die Bedienungsseite 16 gegenüber dem Tisch 12 und damit gegenüber dem Fuß-Bedienschalter 15 unverändert ist, bedarf es keiner Änderung des Bedienschalters 15. Die Lage des Schwenklagers 24 mit der Achse 25 ist so gewählt, dass die Bedienungsperson sich in beiden Arbeitsstellungen der Nähmaschine 1 entsprechend den Figuren 5 und 6 in unveränderter bequemer Haltung vor der Nähmaschine 1 bzw. dem Tisch 10 aufhalten kann. Zweckmäßigerweise befindet sich das Schwenklager 24 also in der Nähe der Nadelstangen-Achse, was bei der geschilderten Ausgestaltung leicht realisierbar ist.Since the operating side 16 with respect to the table 12 and thus with respect to the foot control switch 15 is unchanged, it requires no change of the control switch 15. The position of the pivot bearing 24 with the axis 25 is selected so that the operator in both working positions of the sewing machine. 1 according to the FIGS. 5 and 6 in an unchanged comfortable position in front of the sewing machine 1 and the table 10 can stop. Conveniently, the pivot bearing 24 is thus in the vicinity of the needle bar axis, which is easily feasible in the described embodiment.
