Abstract (en)
[origin: JPH04292192A] PURPOSE: To provide a reliable and inexpensive sewing machine by pulling out a metallic piece rather than mechanically working a solid block by considering the mutually complicated shape of a slide way. CONSTITUTION: A first driving mechanism 22 has a driving shaft 3 and a driving device 8 and the opposite end parts of the two are kinematically connected to the shaft 3 by two connecting rods and a lever transmission. One of them demarcates a first moving orbit in a direction parallel with the supporting surface of a cloth and the other demarcates a second moving orbit in a direction vertical to this surface. An adjuster used therefore is provided with a slide way 20 in the shape of a circular arc in a center of the orbit plotted by a link 12 between the connecting rods of mechanism 22. The slide way 20 is mounted in the state of being freely rockable around the shaft 3 passing through an orbit and a tracer means is engaged with the slide way 20 and integrated with the shaft 3.

Le dispositif de réglage de l'amplitude et du sens de l'entraînement du matériau à coudre comporte un mobile (15) muni d'une denture (17) pour entraîner. Ce mobile comporte une coulisse formée par deux pistes en arcs de cercles concentriques (20a,20b) dont l'une est engendrée par un cône et l'autre, par un cylindre tous deux roulant sur la trajectoire d'un axe (12) d'articulation entre deux leviers du mécanisme d'entraînement. Les deux pistes (20a,20b) de la coulisse sont formées par une feuille métallique profilée, rapportée sur le mobile (15). <IMAGE>
