Description of the new type: [Technical field to which the new type belongs] The new field of the present invention relates to a sewing machine, which includes a base plate; 5 a supporting plate; a pivot shaft for pivotally fixing the base plate to the supporting plate. The X pivot bearing includes at least one pivot joint having a pivot axis, the pivot joint including at least one support element fixed on a support plate, and the pivot joint including at least one pivot element fixed on a base plate; and At least one support spaced from the pivot axis for supporting the substrate on a support = plate; the pivot element can be connected to the substrate at several different and discrete fixing points, one each Above the other is used to set a plurality of discrete positions where the support plates are inclined with respect to the substrate. [Previous technical name]] New background Sewing machines of the type mentioned at the beginning are explained in GB2277101A. The stability of this known sewing machine needs to be improved. A sewing machine including a pivot bearing is described in German patent 875294. In particular, in the case of a column-type sewing table sewing machine, it is necessary to tilt the sewing machine toward the operator side in order to provide good visibility of the stitch formation area '. This is not jealous of the sewing machine of German patent 875294. DE20208849U1 describes a device that makes such tilting possible. The device has a grate shaft for infinitely variable adjustment of the tilt of the substrate with respect to the support plate, including a clamping device and a threaded spindle adjustment device . (Xi device) The release of the clamping device cannot be reliably prevented at all times, and thus the stability of the machine to the base 20 M271880. A maximum of three inclined positions of the substrate with respect to the support plate have been given. This number of inclined positions has proven to be sufficient in practice. Tilt positions that have proven to be particularly ergonomic include: the tilt angle of the base plate 5 relative to the support plate is 2 to 5. , Preferably 3.5. ; And the inclination angle of the substrate with respect to the support plate is 5 to 9. , Preferably 7. . The advantages of the pivot bearing used in the sewing machine correspond to the advantages of the sewing machine according to the present invention. Brief description of the drawings 10 From the following description of the exemplary embodiments in conjunction with the drawings, the details of the present invention will be apparent. Among them, the first view of a sewing machine viewed by the operator Fig. 2 疋 a top view of the sewing knife i of Fig. 1 according to the arrow Π of Fig. 1, Fig. 3 is a front view taken along the line of Fig. 2 viewed from the-side of the needle; Μ Figure 4 is a detailed and enlarged view of Figure 3, in which the base of the sewing machine is inclined with respect to the support plate; Figure 5 is a view along the line ν_ν of Figure 3, where it can be seen Details of the pivot joint located behind the 20 support plate; Figure 6 第 Most of the views corresponding to the view of Figure 5, where the relative position of the base and the support plate has changed compared to Figure 5; " Figure 7 is a view of the other relative positions of the base plate and the support plate corresponding to Figures 5 and _; M271880 Figure 8 is a view according to Figure 7. Partial cross-section side of the drag shaft joint of the front vm implements the cold type] Detailed description of the preferred embodiment 5 The sewing machine 1 seen in the drawings includes-a base plate in the form of a casing 2 'an upper arm 3 and a The pillar 4 joining the two. Therefore, the slit m is approximately c-shaped. : The arm shaft 5 is usually housed in the arm 3, so that the needle rod 6 with the needle 7 is raised and lowered by the-crankshaft transmission 8 actuated. The arm shaft 5 is actuated by a drive motor (not shown). A fishing piece / shuttle 0 piece 10 located in the base plate 2 and assigned to the needle 7 is actuated by the arm shaft 5 through a belt transmission piece 9. The sewing machine 1 is a column-type sewing table. A post ㈣ is supported on the base plate 2 and the piece 10 is arranged inside the post u. The post is closed above the 4-hook piece ig by a top pin plate 12 and is located in the arm 3 for carrying out by a presser cup 14 A presser foot 13 reciprocating up and down contacts the needle plate 12 15. A stitch formation region 15 is formed near the needle plate 12. The base plate 2 and further the sewing machine 1 are supported by a sewing machine table (not shown) by a pivot bearing formed by two pivot joints 16 and a support structure formed by two rubber bearings 丨 7. On the board 18. The support plate 18 includes a recess 19 for holding the substrate 2. The pivot joint µ is designed in the form of a hinge 20 and includes a rubber support element 20 provided and fixed in an appropriate receiving portion 21 of the support plate 18. Each support member 20 has a support groove 22 for receiving a bearing pin 23 of a pivot member 24 of the pivot joint 16. The bearing pins 23 of the two frame shaft joints 16 are each pivoted about a common horizontal pivot axis 25 parallel to the arm shaft 5. The swivel element 24 also includes a support rib 26 which is bent elbow downwards M271880. As can be seen from the figure, each pivoting element 24 is made of a metal plate, and the bearing pin 23 is fixed to the pivoting element 24 by rolling. The bearing pin 23 and, furthermore, the pivoting element 24 are held in position in the support groove 22 by a stopper plate 27 fixed to the support plate 18. It can be seen from 5 to 5 that the stretcher plate 27 holds the bearing pin 23 in its position, but does not hinder the pivoting element 24 and its supporting rib 26 from pivoting upward. Inside each support rib 26 are provided three pairs of through holes above the other, namely a pair of bottom through holes 28, a pair of middle through holes 29 and a pair of top through holes 30 °-pair of screw holes 31 (respectively ) It is arranged in the base plate 2 so as to fit into the screw 32 in the form of a countersunk screw. With these screws 32, and depending on whether the screws are screwed into the screw holes 31 through the top through hole 30, the middle through hole 29 or the bottom through hole 28, each support rib 26 can be fixed to the base plate 2 at three different heights. on. The supporting rib 26 of the pivoting element 24 and its through holes 28, 29, 30 are combined with the screw hole 31 and the screw 32 to form a fastening device / structure 33. One pair of through-holes 28, 29, 30 above the other 15 constitutes all three possible discrete fixings that hold the support rib 26, and thus the pivoting element 24 on the base plate 2 to the pivot joint 16 There may be three relative positions between the nearby substrate 2 and the support plate π. The rubber mount 17 is near the operator's side 34. They are also arranged in the respective receiving portions 35 of the support plate 18 of the support 20. 1 to 3 and 5 show that the substrate 2 is located at a position relative to the support plate 18. In the first relative position, the screw K passes through the pair of bottom through holes 28 and is inserted into the screw hole 31 of the substrate 2. In this first relative position, the substrate plane% given by the substrate 2 is parallel to the M271880 plate plane 37 supported by the support plate with a given one. Therefore, the base plate 2 and thus the sewing machine 丨 are not inclined with respect to the support plate 18. As can be seen from the figure of Fig. 6, in the second opposite position of the base plate 2 and the support plate a, the 'screw 32 passes through the pair of central through holes 29. As a result, the pivot member 24 is displaced downward from the substrate 2 with respect to the substrate plane 36. The sewing machine 丨 is inclined toward the operator side 34 by an angle a which is between the substrate plane% and the support plate plane 37 and ranges from 2 to 5. Between, preferably about 35. . In the illustrations according to Fig. 5 and Figs. 7 and 8, screws 32 pass through the pair of top through-holes 30 and are fixed to the base plate 2 so that the pivoting element 24 is further displaced downward 10. As a result, the substrate 2 and further the sewing machine 1 are further inclined toward the operation side 34, in which case, the angle & between the substrate plane 36 and the support plate plane 37 ranges from 5 to 9. In between, it is preferably 7. . [Taiwan brief description] Details of the model, of which ...
