Abstract

PROBLEM TO BE SOLVED: To provide a hand sewing needle for facilitating the threading by forming a threading frame in the central part of a prescribed length of a wire, by forming stack base parts in the both ends, and by inserting the stack base parts in an axial bottomed hole provided in the hand sewing needle head part. SOLUTION: An axial bottomed hole 12 is formed in the head part 11 of a hand sewing needle main body 10 whose tip is pointed, by electric discharge machining or laser beam machining, and a threading frame 26 is attached using the bottomed hole 12. The threading frame 26 is formed by bending a prescribed length of a steel wire 20 such as a piano wire into a rhomboid or by curving a synthetic resin linear material 20 into a loop, the threading frame 26 is formed in the central part of the wire 20, and the stack base part 12 is formed in both ends 21, 21. The base 22 is inserted and arranged in the bottomed hole of the needle main body 10 so as to be fixed by a joint material 30 such as soldering and an adhesive. If such a threading frame 26 is provided, the threading can be facilitated irrelevant to the thickness of the hand sewing needle and thread.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand sewing needle through which a sewing thread can be easily passed.

[0002]

2. Description of the Related Art A conventional hand sewing needle has a sharpened tip so that it can be easily passed through a cloth or the like, and a through hole called an eyeball for passing a sewing thread is opened in a head. Although there is no problem, the thinner the hand sewing needle and the suture, the narrower the through-hole and the more difficult it becomes to pass the suture. In addition, this conventional hand sewing needle becomes a so-called presbyopia, and becomes an extremely difficult tool for the elderly who have reduced hand / finger sensations. There is a problem that you have to ask young people.

[0003]

The problem to be solved is that, in the conventional hand sewing needle, the thinner the hand sewing needle and the thread, the thinner the through hole becomes, and the more difficult it becomes to pass the thread through. In addition, it is more difficult for elderly people who have presbyopia and their hands to be clumsy, and the present invention solves the above problems and provides an easy-threading hand sewing needle.

[0004]

As shown in the drawing, the hand sewing needle according to the first invention forms a threading frame 26 at the center of a wire 20 of a predetermined length and overlaps both ends 21 and 21. A base portion 22 is formed, and the superposed base portion 22 is inserted into an axial bottomed hole 12 provided in the hand sewing needle head 11 and fixed.

As shown in FIGS. 1 to 3, the hand sewing needle according to the second invention forms a threading frame 26 at the center of a steel wire rod 20 of a predetermined length and twists it at both ends 21, 21. To form the polymerized base portion 22, the polymerized base portion 22 is inserted into the axial bottomed hole 12 provided in the hand sewing needle head 11, and is fixed by the bonding material 30.

The hand sewing needle according to the third invention is shown in FIGS.
As shown in the figure, the threading frame 26 is formed at the center of the steel wire 20 having a predetermined length, and the overlapped base 22 is formed by twisting the both ends 21 and 21. The polymerization base 22 is inserted into the bottomed hole 12 and fixed by swaging 31.

The hand sewing needle according to the fourth invention is shown in FIGS.
As shown in FIG. 6, a threading loop frame 26 is formed at the center of a synthetic resin wire 20 having a predetermined length, and both ends 2 are formed.
A superimposed base 22 is formed in each of the bases 1 and 21, the superposed base 22 is inserted into an axial bottomed hole 12 provided in the hand sewing needle head 11, and is fixed by a bonding agent 30.

[0008] A method for manufacturing a hand sewing needle according to the fifth invention is as follows.
A step of providing a bottom hole 12 in the axial direction in the hand sewing needle head 11 by electric discharge machining;
And a step of forming a polymerized base 22 at both ends 21 and 21, and a step of inserting and fixing the base 22 into the bottomed hole 12.

A method for manufacturing a hand sewing needle according to a sixth aspect of the present invention comprises:
Hand sewing needle head 11 with laser-processed axial bottomed hole 12
A threading frame 26 is formed at the center of the wire 20 having a predetermined length, and the overlapping base portions 22 are formed at both ends 21 and 21.
And a step of inserting the base portion 22 into the bottomed hole 12 and fixing the same.

According to the hand sewing needle manufactured according to the present invention, the side of the threading frame 26 through which the sewing thread is passed is made large, regardless of the thickness of the hand sewing needle and the sewing thread, and the size of the opening is changed to the conventional through hole. This makes it extremely easy to thread, so that even the elderly do not need to wear or remove reading glasses while sewing, and also rely on other young people. There is no need. Moreover, the threading frame 26 formed of the wire 20 is easily elastically deformed, and when passing through the thread, is elastically deformed and becomes thin.
After passing through, it returns to its original size, so that there is no problem in sewing work including threading.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described. A hand sewing needle main body 10 has a sharpened tip, and a head 11 has an axial bottomed hole 12 provided by electric discharge machining or laser machining. ing. Reference numeral 26 denotes a threading frame formed by bending a steel wire 20 such as a piano wire having a predetermined length into a rhombus, or by bending a synthetic resin wire 20 on a loop. You.

That is, the threading frame 26 is formed at the center of the wire 20 having a predetermined length, and the overlapping base 22 is formed at both ends 21 and 21. The frame 26 is preferably formed such that the angle α connected to the base 22 becomes an acute angle. further,
As shown in FIG. 2, FIG. 3, FIG. 5, and FIG.
The threading frame 26 is fixed to the head portion 11 by a zero or by swaging 31 as shown in FIG.

The operation will be described. Regardless of the thickness of the hand sewing needle and the sewing thread, the side of the threading frame 26 through which the sewing thread is passed is enlarged, and the opening size thereof is arbitrarily increased as compared with the conventional through hole. This makes threading extremely easy, so that even elderly people do not need to wear or remove reading glasses during sewing work, and do not have to resort to other young people. Moreover, the threading frame 26 formed of the wire 20 is easily elastically deformed and elastically deforms when passing through a thread, but becomes thinner after passing through the thread. There is no problem in sewing work.

[0014]

Since the present invention is configured as described above, threading becomes extremely easy irrespective of the thickness of the hand sewing needle and the thread, and even when the threading frame 26 is enlarged, the sewing operation can be performed. There is no problem at all.
