Definitions

  • US Patent 4,343,248 relates in particular to a sewing machine, the housing of which has a lower arm, an upper arm and an upright connecting these arms, in which at least part of the front face of the upper arm carries a first plurality of ideograms characteristic of '' a corresponding number of different points, capable of being executed by the machine, and in which this upper arm has a cover mounted tilting about an axis substantially parallel to the longitudinal axis of said arm and which can either be folded over this arm, either to be driven in the raised position, distant from the latter, at least part of the internal face of the cover being visible from the front of the machine, in said raised position, and carrying a second plurality of ideograms representative of other points executable by the machine.
  • the cover is mounted in such a way that, in the folded position, in particular when the machine is out of service, it covers only a portion of the length of the upper face of the arm to which it is articulated, leaving discovered the set of ideograms appearing on the front side of the machine frame.
  • the present invention proposes to overcome this drawback for the purposes of both protecting these ideograms and ensuring a suitable aesthetic appearance of the machine when it is out of service.
  • the subject of the invention is a sewing machine of the kind described above, characterized in that the tilting axis of the cover is arranged in such a way that, when this cover is brought into its folded position on the upper arm of the machine housing, it hides the ideograms carried by this arm.
  • the cover has a hinged flap between the rows of ideograms and capable of being folded down on the bottom of the cover in two limit tilting positions in which it mas that one or the other of said rows of ideograms, depending on the limit position of tilting of this flap, the two faces of the latter each carrying at least one other row of ideograms relating to sewing stitches executable by the sewing machine.
  • the sewing machine illustrated in FIG. 1 comprises a base 1 on the right part of which stands an upright 2 carrying two horizontal arms 3 and 4, of which the first, 3, lower, includes in particular a device for driving the fabric, a loop sensor device and a drive and control mechanism for these, all members not shown, and of which the second, 4, upper, in particular carries a needle bar 5, a mechanism for controlling this bar, not shown, and a presser foot 6.
  • This sewing machine is an electronic machine of microprocessor type, that is to say a machine in which the instructions necessary for the control of the needle, of the device for driving the sewing fabric and of the loop sensor device , for example with a view to obtaining various sewing patterns, are stored in digital form in one or more electronic memories, ROM, PROM, RAM etc. and are read by a microprocessor on which the control of all the functions of the machine.
  • These instructions can, in particular, relate to the execution of sewing patterns of different types that the user can preselect individually, with a view to their subsequent execution, by actuation, in particular, of a keyboard CL, with ten keys, marked with 0 at 9 and thanks to each which can be written in one of the previously mentioned memories, a digit of value corresponding to that of the number it carries, by successive pressing of the key concerned and an IT insertion key.
  • this keyboard it is in particular possible to memorize the numbers of one, two or three digits whose value is characteristic of a given type of sewing pattern, capable of being executed by the sewing machine.
  • Such a machine is indeed able to sew up to 999 different patterns, provided of course that the memory or memories with which it is provided include corresponding sewing instructions.
  • an electronic machine of the kind represented could very well include an integrated memory of sufficient capacity to store the instructions necessary for the execution of the 999 patterns cited. Such a memory will however be both cumbersome and delicate.
  • the solution of an integrated memory of moderate importance that is to say capable of containing instructions in limited number, for example concerning around 200 patterns, and additional memories, of plug-in type on the machine, as for example in the case of the "Symphony 300" sewing machine sold by Singer or the Elna® 7000 machine.
  • each cassette has an additional memory containing instructions for a hundred patterns sewing.
  • the machine illustrated in the drawing makes it possible precisely to obviate this kind of drawback while presenting, at the same time, a beautiful aesthetic appearance and a practicality of use evident in the selection of the patterns to be sewn.
  • the machine according to the invention is provided with a first table T1 (fig 2) constituted, in this case, by two superimposed rows of ideograms, carried horizontally over the greater part of the length of the upper arm 4 of the machine housing, and a second table T2 housed inside a cover 7 (fig 2) articulated around an axis 8 (fig 3 and 5) mounted at the top of the front face of the housing of the machine.
  • a first table T1 (fig 2) constituted, in this case, by two superimposed rows of ideograms, carried horizontally over the greater part of the length of the upper arm 4 of the machine housing
  • a second table T2 housed inside a cover 7 (fig 2) articulated around an axis 8 (fig 3 and 5) mounted at the top of the front face of the housing of the machine.
  • the cover 7 can be driven in two limit tilted positions, one folded down on the front face of the machine housing, in which it completely covers the table T1 of ideograms, the other raised and slightly inclined towards the rear of the machine, in which the user can see, in addition to the table T1, the ideograms that comprise the table T2 previously mentioned.
  • each file 9 and 10 comprises only about twenty ideograms, it being understood however that this number is not limiting and that it only depends on the length which we will want to give to cover 7 and the size and arrangement chosen for the ideograms.
  • a flap 11 Between the lines 9 and 10 of ideograms, which comprises the bottom of the cover 7, is mounted a flap 11 at the two ends of which project axes 12a and 12b, extending parallel to the axis 8 cited and each pivoted in a corresponding opening of the side walls of the cover 7; this flap can therefore be driven, by tilting, in two limit positions in each of which it comes to rest on the bottom of the cover 7 by covering either the ideograms of the queue 9 (fig 4), or those of the queue 10 (fig 3) .
  • each side of the flap 11 is, in turn, covered with a file 13, respectively 14, of twenty ideograms corresponding in total to forty other different types of patterns.
  • the ideograms of the flap 11 are placed, on each face, in such a way that, in one or the other of the two folded positions thereof (figs 3 and 4), each ideogram of the flap is very exactly above a given ideogram, belonging to the lines of ideograms 9 and 10 of the cover 7 so that, whatever the position of the flap 11, the general appearance of the table T2 remains unchanged for the user.
  • table T1 comprising only two superimposed rows of ideograms traced on the housing of the sewing machine or, alternatively, arranged on an intermediate support attached to this housing, it is obvious that such a table T1 could have another structure.
  • the cover 7 could be removably mounted so that it can be replaced, if necessary, by another cover of identical structure but the bottom of which would be covered with ideograms of different types: this variant would be implemented in particular in the case of the use of the additional plug-in memories already mentioned.
  • the invention is of course not limited to what has been shown and described: in particular, it will be understood that it could very well be adapted to a sewing machine whose keyboard would be of structure different from that envisaged here, by example comprising only two or three keys intended, to control, by repetitive actuation of each of them, the incrementation, of a corresponding number, of display units of units, tens and hundreds, in view to form a figure corresponding to that of the code characteristic of the desired pattern, another key making it possible to memorize this figure and thus to select the part of the memory concerned by this pattern.
