  However, the above conventional techniques have the following problems.

  First, in order to make it easier to pick up the eye of the yarn when knitting, the tip portion of the bar needle portion is reduced in a taper shape. This diameter reduction is particularly noticeable when the needle axis of the bar needle portion is thick. Therefore, when bamboo or the like is selected as the material for the bar needle portion, the tip portion may pierce the human body. In particular, there is a problem that a younger child is dangerous when used.

  Furthermore, in the above prior art, since the bar needle portion and the connecting strip portion are different members, a step of connecting the two in manufacturing the needle is required, which is a problem in terms of manufacturing effort and cost. It was.

  In view of the above problems, the problem to be solved by the present invention is to provide a ring needle that is highly safe, easy to manufacture, and inexpensive to manufacture.

  In order to solve the above-described problem, a ring needle according to the present invention is a ring needle provided with two bar needle parts and a string-like connecting strip that connects the rear ends of the bar needle parts. At least a head portion thereof is formed of a synthetic resin that is flexibly deformed without penetrating a human body, and the connecting strip portion is integrally formed with the bar needle portion with the synthetic resin.

  Due to this specific matter, the needle according to the present invention is formed of a synthetic resin that is flexibly deformed even if the tip of the needle is accidentally strongly hit against the human body. The risk of piercing disappears. Further, the material of the bar needle part is a synthetic resin, and there is no possibility of warping of the bar needle part. Furthermore, since the bar needle portion and the connecting strip portion are integrally formed of synthetic resin, a step of connecting the bar needle portion and the connecting strip portion is not required, and the manufacturing of the ring needle is easy and the manufacturing cost can be reduced.

  The synthetic resin may be polyethylene, polypropylene, polystyrene, or polyvinyl chloride.

  In this case, since these materials are inexpensive, it is possible to reduce the cost for manufacturing the needle.

  Further, the ring needle includes a reduced diameter portion in which an outer diameter of the connecting strip portion is smaller than an outer diameter of the rod needle portion, and an outer diameter of the rod needle portion is reduced to an outer diameter of the connecting strip portion. It may be.

  In this case, since the difficulty of bending of the portion gradually decreases from the rear end portion of the bar needle portion toward the end portion of the connecting strip portion, the ring needle has a moderate waist (hard to bend) near the rear end of the bar needle portion. Have Therefore, there is no possibility of forming an acute angle between the rear end portion of the bar needle portion and the end portion of the connecting strip portion, and the user can smoothly send the yarn knitted by the bar needle portion to the connecting strip portion.

  The ring needle according to the present invention is highly safe because there is no risk of piercing the human body. Moreover, it is easy to manufacture.

It is a front view showing one embodiment of a ring needle concerning the present invention. It is an enlarged view of A part in FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a front view showing an embodiment of a ring needle according to the present invention. FIG. 2 is an enlarged view of a portion A in FIG.

-Configuration of the ring needle-
As shown in FIG. 1, the ring needle 1 includes two bar needle portions 2 and a string-like connecting strip portion 3 that connects the rear ends of the bar needle portions 2.

  The bar needle portion 2 includes a head portion 5, an intermediate portion 6, and a reduced diameter portion 4 in order from the tip. The bar needle portion 2 is formed of polyethylene that can be flexibly deformed without being pierced into the human body even if the head portion 5 abuts against the human body. The portion to be flexibly deformed may be only the top portion 5 but may include up to the intermediate portion 6.

  For example, the leading end 5 is a hemispherical surface having an outer diameter of about 2 mm, for example, and the outer diameter of the front end is expanded to the outer diameter of the intermediate portion 6. For example, the tapered surface has a length of about 20 mm. It has.

  The intermediate part 6 has a cylindrical shape with an outer diameter of 5.1 mm and a length of about 60 mm, for example.

  As shown in FIG. 2, the reduced diameter portion 4 has the outer diameter of the bar needle portion 2 reduced to the outer diameter of the connecting strip portion 3. For example, the reduced diameter portion 4 has a length of about 20 mm, and a portion 41 adjacent to the connecting strip 3 has a taper in which the inclination gradually decreases as the connecting strip 3 is approached.

  This reduced diameter portion 4 gradually reduces the difficulty of bending as it goes from the rear end portion of the bar needle portion 2 toward the end of the connecting strip portion 3, so that the ring needle 1 has an appropriate waist (bend) near the rear end of the bar needle portion 2. ). Therefore, there is no possibility that an acute angle is formed between the rear end portion of the bar needle portion 2 and the end portion of the connecting strip portion 3, and the user can smoothly send the yarn knitted by the bar needle portion 2 to the connecting strip portion 3.

  The connecting strip 3 is molded from a synthetic resin, and is integrally molded with the bar needle 2 as will be described later. The connecting strip 3 has, for example, a string shape with an outer diameter of 2 mm and a length of about 300 mm. Thus, since the connecting strip 3 is integrally formed with the bar needle 2, the step of connecting the bar needle 2 and the connecting strip 3 is not required, and the manufacture of the ring needle 1 is simplified. Further, since the connecting strip portion 3 is integrally formed with the bar needle portion 2, there is no possibility that the waist of the bar needle portion 2 is broken at the boundary between the rear end of the bar needle portion 2 and the end of the connecting strip portion 3.

  As shown in FIG. 1, the ring needle 1 in which the bar needle portion 2 and the connecting strip portion 3 are integrally formed has an arc shape in a state where no external force is applied, and the connecting strip portion 3 is formed at both ends of the connecting strip portion 3. Two provided needle needle portions 2 form a square shape. Thus, since the tip of the bar needle portion 2 approaches naturally, the user does not need to apply force when knitting, and knitting becomes easy.

-Manufacturing method for needles-
The ring needle 1 is integrally formed by an injection molding method in which a mold for the ring needle 1 is prepared and resin is injected into the mold. Thereby, the ring needle 1 can be easily mass-produced and the manufacturing cost can be suppressed.

-How to use the needle-
The circular needle 1 can be used not only for circular knitting but also for flat knitting for knitting a flat knitted fabric.

  When the knitting needle 1 is used to advance knitting in only one direction, a tubular knitted fabric is formed. Thereby, a hat, a neck warmer, etc. can be knitted.

  When the knitting needle 1 is used for reciprocating knitting, a flat knitted fabric with the length of the knitting needle 1 as the limit is formed. Thereby, a muffler etc. can be knitted.

  Since the needle 1 is connected to the two needles, there is no possibility that the needles will fall apart even when knitting is interrupted. Therefore, it is convenient when knitting in a car when moving.

-Effect of wheel needle-
Since such a ring needle 1 is molded from polyethylene, it is possible to obtain an appropriate flexibility. Therefore, when it hits the human body, there is no risk of being easily deformed and piercing the human body, and the safety is high. Also resistant to moisture. In addition, since it is integrally molded, it is easy to manufacture and can be provided at low cost. In addition, since the material of this ring needle 1 is polyethylene, the sliding of the yarn is not so good as compared with conventional bamboo or the like, but conversely, it is advantageous for children and beginners to knit without dropping the stitches. It becomes.

-Other embodiments-
In addition, in the said embodiment, although the ring needle 1 was shape | molded with polyethylene, it is not restricted to this, You may shape | mold with synthetic resins, such as a polypropylene, a polystyrene, or a polyvinyl chloride. In these cases, since these materials are inexpensive, the cost for manufacturing the needle can be suppressed.

  The intermediate part 6 of the bar needle part 2 has an outer diameter of 5.1 mm (No. 10), 5.7 mm (No. 12), 6.6 mm (No. 15), 8 having rigidity sufficient for use as a bar needle. A thickness of about 0.0 mm is preferable. These are used for knitting very thick to very thick yarns. However, the bar needle portion 2 is not limited to the one having the length, the outer diameter, and the taper angle as described above, and may be one having a length, an outer diameter, and a taper angle that can be easily used as a ring needle. Further, the bar needle portion 2 is not limited to the above-described shape, and for example, the head portion 5 may be a columnar shape, or the head portion 5 may be provided with a hook.

  The connecting strip 3 is not limited to the length and thickness as described above, but may be any length and outer diameter that can be easily used as a ring needle. The cross section of the connecting strip 3 is not limited to a circle, and may be an ellipse, for example.
