Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a circular needle used for hand knitting of woolen yarn, etc.

[Conventional technology]

Traditionally, a pair of knitting needles made of bamboo, metal, etc.
Each knitting needle has a cylindrical metal fitting fixed to the rear end thereof, and a filament made of flexible synthetic resin, etc., and each knitting needle and the filament are connected to each other through the metal fitting. There is a ring needle that is connected. Some of these circular needles are formed so that the knitting needle and the filament are fixed to each other by a metal fitting so that the knitted fabric can smoothly transfer along the knitting needle and the filament.
-24288). In such circular needles, when the filament is twisted during knitting work, the force of this twist is transmitted to the knitting needles, adversely affecting the knitting work.

On the other hand, there is one in which the knitting needles are configured to be rotatable relative to the filament. That is, as shown in FIG.
The filament body 1 is loosely inserted into the insertion hole 32 of the metal fitting 3, so that the filament body 1 and the knitting needle 2 are rotatably connected. In such a circular needle, the torsional force is not transmitted to the knitting needle 2, but for example, when a force is applied to the filament 1 in the direction of arrow A, the tip 111 of the internal locking portion 11 is transferred to the knitting needle 2. The filament 1 is fitted into the internal space 32 of the metal fitting 3 until it comes into contact with the rear end surface 21 of the metal fitting 3. At this time, there is a problem that the yarn used for knitting may become entangled in the insertion opening 32.

In order to solve this problem, the present applicant formed the external locking part 12 so as to be in contact with the outer surface of the insertion hole 32, as shown in FIG. A circular needle in which the insertion opening 32 is sandwiched between the contact and locking portions 11 has already been proposed.

[The problem that the idea aims to solve]

However, since the internal locking portion 11 of the circular needle formed as shown in FIG.
A space 33 is created between the metal fitting 3 and the inner wall, for example,
When the filament 1 is pulled in the direction of arrow B, the internal locking portion 11 is elastically deformed, and the rear end portion 112 is pressed against the inner wall of the metal fitting 3. As a result, a gap is created between the circumferential locking portion 12 and the insertion opening 32, and there is a problem in that yarn or the like may be caught in this gap.

An object of the present invention is to provide a circular needle that prevents the formation of a gap between the circumscribed locking part and the insertion opening even when the filament is stretched.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a pair of knitting needles, a cylindrical metal fitting fixed to the rear end of each knitting needle, and a flexible striated body, In the circular needle in which the filamentous body is connected to the metal fittings, the filamentous body has a circumferential locking portion formed in contact with the outer surface of the insertion port of each of the metal fittings, and a circumferential locking portion formed in contact with the outer surface of the insertion port of each of the metal fittings, and and an internal locking portion formed in contact with each other, the rear end of the internal locking portion and the inner wall around the insertion opening of the metal fitting are in close contact, and the filament is rotated with respect to the metal fitting. They are connected so that they can move freely.

[Effect]

According to the circular needle having the above structure, the rear end of the internal locking portion and the inner wall around the insertion opening of the metal fitting are in close contact with each other, so even if the filament is pulled, the internal locking portion remains elastic. To prevent deformation and to prevent a gap from forming between the circumscribed locking part and the insertion opening.

〔Example〕

FIG. 1 shows a circular needle according to the present invention.

A pair of knitting needles 2 are connected to both ends of the filament 1 via metal fittings 3, and a circumscribed locking portion 12 is formed in contact with the outer surface of the insertion opening 32 of each metal fitting 3. Then, as shown in FIG.
A substantially spherical internal locking portion 11 is formed in contact with the inner surface of the holder. The curved surface of the rear end portion 112 of this internal locking portion 11 and the curved surface of the inner wall 34 around the insertion opening of the metal fitting 3 are formed to have almost the same curvature, and a gap is provided between them. They are formed so that they are close to each other. Further, a connecting portion 13 that connects the internal locking portion 11 and the external locking portion 12 is loosely fitted into the insertion hole 32, so that the filament body 1 and the metal fitting 3 are rotatably connected. There is.

By forming as described above, even if the filament 1 is pulled in the direction of the arrow C, no gap will be formed between the circumscribed locking portion 12 and the insertion hole 32.

Note that the shape of the internal locking portion 11 is not limited to a substantially spherical shape, and may be, for example, a hemispherical shape, a substantially spindle shape, etc., as long as it is in close contact with the lower inner wall 34 of the metal fitting 3. Further, the shape of the external locking part 12 is also changed by the external locking part 12 and the internal locking part 11.
For example, it may be approximately spherical or approximately conical, as long as it can be held in place.

[Effect of idea]

In the present invention, the curved surface of the rear end of the internal locking part and the curved surface of the inner wall around the insertion hole of the metal fitting are formed in close contact with each other, so even if the filament is pulled downward, It is possible to prevent a gap from being formed between the circumscribed locking part and the insertion opening, and it is possible to prevent knitting yarn or the like from being entangled and hindering the creation of the knitted fabric.
