[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an embroidery presser with a cord which is detachably attached to a presser bar of a sewing machine.

[0002]

2. Description of the Related Art Conventionally, there is an apparatus disclosed in Japanese Patent Application Laid-Open No. 52-141756 for sewing a thick thread such as a yarn on a cloth, and the conventional apparatus is specially prepared for applying a yarn. Since it was a dedicated machine, ordinary sewing was not possible, and the work of installing the wool was troublesome and time-consuming.

[0003]

SUMMARY OF THE INVENTION The present invention can be used in a household sewing machine, which is the second most widely used next to a television and a refrigerator, and can be used for embroidering by replacing with a general-purpose cloth foot that is already installed. It is an object of the present invention to facilitate the insertion of the wool into the presser foot.

[0004]

SUMMARY OF THE INVENTION The present invention relates to an embroidery presser which is capable of being attached to a holding bar of a household zigzag sewing machine and capable of performing ordinary sewing including straight stitching and zigzag sewing. When the needle is pierced with the cloth, the cloth is held down when the cloth is not pierced with the needle. An embroidery presser with a cord has been made possible in which embroidery with a three-dimensional effect is facilitated by forming a wide inclined receiving portion on the outer side with a groove, thereby facilitating the operation of inserting the wool.

[0005]

According to the present invention, the holding arm of the zigzag sewing machine for home use has an engaging arm interlocked with the vertical movement of the needle bar via a mounting body via a mounting body, a sliding shaft for fixing the cloth, and a cloth which is constantly urged downward by a compression spring. In the embroidery presser with a string constituted by the presser portion, an attaching portion to a presser bar is provided on the attaching body, and a thick thread such as wool is provided on the cloth presser portion so that the longitudinal axis of the thick thread matches the vertical movement direction of the needle. The needle drop hole is provided so that the needle thread can be inserted into the needle drop hole by providing a fine groove into which the yarn can be inserted and a wide inclined receiving portion having an outer side continuous with the fine groove. The present invention is characterized in that a three-dimensional embroidery with a cloth can be performed by repeatedly piercing the cloth with the needle moving up and down through the axis of the string.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described below with reference to the drawings. The needle bar 1 is supported by an arm machine frame so as to be vertically movable.
A needle 3 is fixed to the lower end of the needle bar via a needle stopper 2. The presser bar 4 is supported by the arm frame so as to be movable up and down in parallel with the needle bar 1, and an embroidery presser 6 with a cord is fixed to the lower end of the presser bar via a tightening screw 5.

The embroidery presser with a cord is composed of main components of a mounting body 7, a slide shaft 8, a cloth presser 9, and a compression spring 10. The mounting body 7 is provided with horizontal portions 11 and 11 having through holes parallel to each other and having the same axial center at upper and lower ends, and a vertical hole 13 is formed in a vertical wall 12 connecting both horizontal portions.
Further, a presser rod mounting portion 14 is provided at the laterally extended end.

The sliding shaft 8 is connected to the horizontal portion 1 of the mounting body 7.
1 and 11 are slidably supported in the through holes, and a fixed retaining ring and an upper horizontal portion 11 are fixed at appropriate positions between the upper and lower horizontal portions.
The compression spring 10 is mounted between the sliding piece 15 and the sliding piece 15 formed at the lower end at the front end and bent vertically at the rear end.
A base 16 is formed, and an engagement arm 17 is fixed to the upper end of the base 16 to be engaged with the cylindrical portion formed on the needle stopper 2.

The sliding piece 15 is fitted in the vertical groove 13 of the mounting body 7 to prevent the cloth presser 9 from rotating on the sliding shaft 8 when the needle bar 1 is moved up and down. Guide the movement.

[0010] The cloth presser 9 is provided with a needle drop hole 18 through which a thick yarn F such as a wool penetrates and which allows a needle amplitude in a range of 1 to 2 mm. Micro-groove 19 communicating therewith and inclined receiving portion 2 expanding outside the micro-groove
0 is provided.

Since the present invention is constructed as described above, the cloth W is placed on the needle plate 21 and inserted under the cloth presser 9 so as to pass through the fine groove 19 from the inclined receiving part 20 into the needle drop hole 18. When the sewing machine is operated after inserting the thick thread F, the presser foot 9 is moved up and down in conjunction with the up and down movement of the needle bar 1.

When the needle bar 1 moves upward and the needle 3 moves upward from the cloth W, the cloth presser 9 moves away from the cloth W and moves upward (position U in FIGS. 4 and 5). In a state where the needle 3 penetrates the cloth, the cloth presser 9 moves downward (position L in FIGS. 4 and 5), and the cloth W is sewn to the needle plate 21 via the thick thread F sewn on the cloth. Press

When the needle 3 descends, the thick thread F is held vertically in the needle drop hole 18 of the cloth presser 9, so that the needle 3 is pierced in the longitudinal direction of the thick thread F to remove the cloth. Pierce. By changing the feed direction of the cloth W, the needle thread T is exposed on the sewn thick thread F (in the forward state shown in FIGS. 4 and 5) or hidden (in the backward state in FIG. 6). Can be done. At the time of embroidering, it is also possible to sew the thick thread F on the cloth by moving the needle 3 with an amplitude of 1 to 2 mm.

[0014]

The present invention has the above-described structure and operation. By operating the sewing machine by passing a thick thread such as wool through the needle drop hole of the presser foot, the thick thread is formed on the presser foot. Since the needle is held by the needle drop hole, the needle can surely catch and pierce the thick thread. Therefore, it is possible to sew a thick thread on a cloth in accordance with a design rich in decorativeness, or to superimpose the thick thread three-dimensionally to perform an embroidery with a nice-looking string. Further, by changing the cloth feeding direction, the needle thread can be concealed and stitched, and a thick thread can be inserted into the needle drop hole of the cloth holding part by providing the inclined receiving part and the minute groove in the cloth holding part. The work becomes extremely easy, and on the other hand, it prevents the escape of the thick thread from the needle drop hole, and is effective in facilitating the operation as the range of the sewing applied to the sewing machine is expanded.
