Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a presser foot of a sewing machine having a function of temporarily holding a fastener through a guide groove for sewing a fastener to a cloth or other attachment portion.

[0002]

[Prior art]

 Conventionally, a presser foot of a sewing machine provided with a guide groove so as to be able to move at a sewing speed through a tooth portion when sewing a fastener is used. However, when the fastener is sewn with the conventional presser foot, there is a gap t between the sewn cloths s and s when the fastener is closed, and there is a drawback that the fastener z can be seen from there. . See FIG.

[0003]

[Problems to be solved by the invention]

 The present invention has been made by paying attention to the above-mentioned point, and a problem thereof is to realize a sewing in which the fastener is not visible from between cloths to which the fastener is sewn. Therefore, passing the needle through the base of the fastener is one of the objects of the present invention.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention forms a guide groove for passing the fastener in two lines parallel to the lower side of the main body, and forms a drooping piece that separates both guide grooves in a sharp tapered shape, and furthermore, the main body has A vertically extending needle hole is formed in the middle of the two guide grooves, and the fastener passing through the guide groove is inclined to expose the base of the fastener to the needle hole, so that the guide groove extends outward from the axis passing through the needle hole. In order to guide the fastener into the inclined guide groove, a receding surface is formed on the front surface of the main body, which recedes from the center to the left and right.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The presser foot A of the sewing machine M according to the present invention has a function of temporarily holding the fastener Z through the guide grooves 11 and 12 to sew the fastener Z. Here, "holding" means that the fastener Z is guided to a substantially constant state so as not to shift.

The presser foot A has two parallel left and right guide grooves 11 and 12 through which the fastener Z passes, on the lower side of the main body 10. The two guide grooves 11 and 12 are separated by an intermediate hanging piece 13. When the fastener Z is passed through the guide groove 11 on the left side, the fastener Z is disposed beyond the guide groove 12 on the right side as shown in FIGS. Conversely, when passing through the guide groove 12 on the right side, the guide groove 11 is disposed from the side of the guide groove 11 on the left side.

The hanging piece 13 is formed to be as sharp as possible. Further, a vertically penetrating needle hole 14 is formed in the main body 10 in the middle of the two guide grooves 11 and 12. Therefore, it can be seen that the needle hole 14 also penetrates the hanging piece 13 and the hanging piece 13 is in a state of holding down the base u of the fastener Z. See FIG.

In other words, the guide grooves 11, 12 are inclined outwardly from the vertical line V of the needle N passing through the needle hole 14 in order to incline the fastener Z passing therethrough to expose the base thereof to the needle hole 14. To incline. The tapered shape of the hanging piece 13 reflects the above inclination of the guide grooves 11 and 12. See FIG. 3 and FIG.

Further, in order to guide the fastener Z to the inclined guide grooves 11 and 12, retreating surfaces 15 and 16 are formed on the front surface of the main body 10 so as to retreat left and right from the center. The front edges 17, 18 of the inclined guide grooves 11, 12 recede due to the combination with the retreating surfaces 15, 16, so that they abut the fastener Z obliquely, and guidance for the inclination is made more smoothly. Become so.

The presser foot A of the illustrated embodiment has a rectangular parallelepiped main body 10 in which two guide grooves 11, 12 and a needle hole 14 are formed. Are formed. Reference numeral 19 denotes a mark indicating the position of the needle N, and reference numeral 20 denotes a connecting portion for attachment to the presser foot shaft 21 on the sewing machine side. The connecting portion 20 is set up on the rear portion of the main body 10, has a groove portion 22 for fitting a presser shaft 21, and further has a small opening 23 for screwing facing the groove portion 22. The fore edge 23 may be notched. Needle hole A cutout portion 24 may be formed in the hanging piece 13 at the rear.

Therefore, when using the presser foot A according to the present invention, after attaching to the presser foot shaft 21, one of the meshing teeth of the fastener Z is inserted into the right guide groove 12, for example, in the case of the right meshing tooth. Pass it over from the side so that it fits into the guide groove 11 on the left side. See FIGS. 4A and 4B. The fastener Z passed through the guide groove 11 is tilted outward (solid line in FIG. 4A), and its base u passes through the left position near the center of the needle hole 14 (FIG. 4B). ). Therefore, the sewing thread T is sewn to the zipper Z on the cloth side W at the base u of the meshing teeth, so that the necessary and sufficient sewing margin can be obtained, and the gap t which has conventionally occurred between the sewn cloths is completely eliminated. Can be.

[0012] In the present invention, the zipper is used to tightly and continuously open and close adjacent pieces (W, W) of woven fabric, leather, and other materials by a set of meshing teeth having substantially the same structure. It is used as a generic name for sliding fasteners that are joined together as much as possible, and is synonymous with zipper. In FIG. 5, X indicates a joint between adjacent pieces W and W according to the present invention.

[0013]

[Effect of the invention]

 Since the present invention is constructed and operated as described above, a needle or a sewing thread can be passed through the base of the fastener, so that the fastener cannot be seen through the cloth (adjacent piece) to which the fastener is sewn. As a result, high quality fasteners can be installed.
