Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a knitting needle for a knitted cloth which is mounted on a circular knitting machine or the like.

[0002]

[Prior art]

 Generally, a knitting needle for knitting (hereinafter abbreviated as a latching needle) attached to a circular knitting machine or the like has a hook 2 for holding a thread connected to a tip of a needle trunk 1 as shown in FIG. A groove 3 is formed on the side of the needle stem that is continuous with the inside of the hook 2, one end of a latch 5 is placed in the groove, and the vertical axis is rocked by a rotary shaft 4 made of a rivet that penetrates the groove 3. It is movably attached and the opening of the hook 2 is opened and closed with this latch 5.

As shown in FIGS. 6 (a) and 6 (b), in the conventional latch 11, the part that goes in and out of the groove 3 (FIG. 1) is formed of a thin metal plate. Is guided by the left and right wall surfaces of the groove 3 and can swing without lateral swing. Further, the contact surface 12 with the front end portion of the hook 2 is formed in a spoon shape, and the peripheral wall of the contact surface engages so as to wrap around the tip end portion of the hook 2 so that the hook 2 can be closed in a closed state. 11 is stable. As shown in Fig. 6 (a), such a latch 11 has a thin plate-shaped portion and a boundary portion between the facing surface spread like a spoon, cut by a flat surface 13, and the portion is constricted. It had a shape.

As another type of latch, as shown in FIG. 3A, a vertical groove 7 is formed on the outer surface of the front end of the hook 2 and is shown in FIGS. 7A and 7B. As described above, the latch 14 is also known in which a protrusion 15 having a triangular cross section is provided so as to be fitted into the vertical groove 7 (so-called spoonless latch).

When the latch needle as described above is attached to the needle cylinder of the knitting machine and the knitting machine is operated, first, as shown in FIG. 1, the latch needle rises to receive the supply of the knitting yarn 16 and the latch 5 faces downward. It rotates in the direction of 1 and passes through the existing stitches 10 along the needle stem 1. Then, as shown in FIG. 2, when the latch needle descends, the latch 5 rotates upward to close the opening of the hook 2, and the knitting yarn 16 held by the hook 2 forms a loop. Escape from the existing stitch 10 to form a new stitch.

[0006]

[Problems to be solved by the device]

 However, the latch needle with the spoon-shaped latch mentioned above has a narrowed portion of the latch (see FIG. 6 (a)) when the latch passes through the existing stitches along the needle stem. There is a problem that it is easy to get caught. In order to make such a narrowed portion smoother, a technique for making the width of the spoon (so-called face width) thinner is required, but this causes a new problem that the strength of the latch becomes insufficient.

In the so-called spoonless latch (FIG. 7), when the latch needle descends and the hook closes, the knitting yarn or its fluff is caught between the ridge and the vertical groove, and There is a problem that the smooth descent is hindered. Further, if the knitting yarn is frequently caught on the vertically moving latch needle, the latch may be deformed, shortening the life of the latch needle, or damaging the knitting yarn.

Therefore, the present invention solves the above-mentioned problems, and prevents the knitting needle for knitting from being caught by the knitting yarn or caught between the hook and the latch during knitting operation. It can move up and down more smoothly, enhance the mechanical strength of the latch to improve the durability of the latch needle, and can reduce the face width of the latch needle with a spoon-shaped latch. The task is to

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, a hook is provided at the tip of the needle stem, and a groove is formed in the longitudinal direction of the needle trunk side surface that is continuous inside the hook, and a rotary shaft that traverses this groove is used. In the knitting needle for knitting in which the latch is swingably mounted in the groove, a spindle-shaped thick portion extending in the longitudinal direction is provided on the side surface of the latch facing the groove width direction.

Alternatively, a hook is provided at the tip of the needle stem, and a groove is formed in the longitudinal direction of the needle trunk side surface that is continuous inside the hook, and a latch is oscillated in the groove by a rotary shaft that traverses the groove. In a freely attached knitting needle for knitting, a vertical groove is formed at the tip of the hook, and a ridge that fits into the vertical groove is provided at the tip of the hook, and the horizontal width of the tip of the latch is the width of the hook tip. It is also possible to employ the configuration provided above. Further, it may be configured such that a spindle-shaped thick portion extending in the longitudinal direction of the side surface is provided on the side surface of the latch facing the rotation axis direction.

[0011]

[Action]

 The knitting needle for knitting according to the present invention has a spindle-shaped thick portion extending to the side surface of the latch along the needle stem when the latch is raised during knitting and the latch is directed downward, and the necked portion is formed on the side surface of the latch. Since it is not exposed, the knitting yarn does not get caught in the latch. Since the relatively long part in the longitudinal direction from the tip of the latch is reinforced by the spindle-shaped thick-walled part, the latch needle has improved mechanical strength and excellent durability.

Further, in the case of a latch needle having a vertical groove formed at the hook tip, since the lateral width of the other end of the latch is set to be larger than the lateral width of the outer surface of the hook tip, the hook tip is covered with a latch just before it is closed. And the knitting yarn or fluff does not get caught between the hook and the latch.

[0013] In the so-called spoonless latch described above, which is further provided with a spindle-shaped thick portion, the knitting yarn is not caught, and when the latch needle rises, the knitting yarn does not catch on the latch and The needle weaving operation becomes smoother.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, in the first embodiment, a hook 2 is formed at the tip of a needle shaft 1, and a groove 3 is formed in the longitudinal direction of the side surface of the needle shaft 1 continuous inside the hook. A latch needle for knitting in which a latch 5 is swingably mounted in the groove 3 by a rotary shaft 4 composed of a rivet that crosses the groove 3, and the side surface of the latch 5 facing in the groove width direction. Is provided with a spindle-shaped thick portion 6 extending in the longitudinal direction of this side surface.

As shown in FIGS. 3 and 4, a vertical groove 7 is formed on the outer surface of the tip of the hook 2, and a protrusion 8 that fits into the vertical groove 7 is formed at the tip of the latch 5. The lateral width L ₁ of the tip of the latch is set to be the same as the lateral width L _{2 of the} outer surface of the hook tip.

The shape of the hook 2 of the knitting needle for knitting or the shape of the spindle-shaped thick-walled portion 6 of the latch 5 is roughly the outer shape of each of which is formed by bending a round bar-shaped metal material and performing compression or the like. It is formed by molding and further cutting. Further, the groove 3 of the needle stem 1 is formed by cutting after molding.

It is preferable that the thick portion 6 is as long as possible within the range where the rotation of the latch 5 is not hindered, because the strength of the latch 5 is improved. The thickness of the thick portion 6 is the same as the side surface of the needle stem 1. It suffices to form almost the same plane. As shown in FIG. 4, in the first embodiment, the spindle-shaped thick-walled portion 6 has its upper edge arranged along the upper edge of the latch 5, and rotates downward to rotate the latch 5 along the needle stem 1. Most of the side surface 5a of the above is covered with the thick portion 8.

The lateral width L ₁ of the tip of the latch 5 may slightly exceed the lateral width L ₂ of the tip of the hook 2, that is, it may be provided so as to cover the tip of the hook 2. Of course.

As shown in FIG. 5, in the second embodiment, a spindle-shaped thick portion 6 extending in the longitudinal direction is provided on the side surface of a latch 9 having a spoon-shaped surface facing the tip of the hook. Is.

In this product, the peripheral wall of the spoon portion and the thick portion 6 are continuous, and there is no boundary between the thin plate-like portion and the spoon-like spread portion as in the first embodiment, that is, There are no constricted parts.

In the first and second embodiments described above, as shown in FIG. 1, when the latch needle rises during weaving, the spindle-shaped thick portion 6 on the side surface of the latch 5 runs along the needle stem 1. The ready-made stitches 10 are not caught on the latch because there is no constriction on the side of the latch 5.

Further, as shown in FIG. 2, in the first embodiment, when the latch needle descends and the latch 5 is lifted by the stitch 10 to close the hook 2, the front end of the hook 2 is Since the tip of the latch 5 is covered, the knitting yarn or the fluff thereof does not get caught between the hook and the latch.

[0024]

【effect】

 As described above, according to this invention, since the spindle-shaped thick-walled portions extending in the longitudinal direction of the latch are provided on the side surfaces of the latch that are opposed to each other in the width direction of the groove formed in the needle stem, the knitting operation is performed along with the knitting operation. The thread does not get caught on the latch, the movement of the latch needle is smooth, and the mechanical strength of the latch improves, so the durability of the latch needle increases, and the face width of the latch can be made narrower and precise. It becomes a pan needle. Also, in a latch needle with a vertical groove formed on the outer surface of the hook tip, the width of the other end of the latch is set to be larger than the width of the outer surface of the hook tip, so that the knitting yarn does not get caught between the hook and the latch. This has the advantage that the weaving operation can be performed more smoothly.
