Description

[Detailed explanation of the invention] Transfer needles that transfer stitches to opposing needles are commonly known, and are used as a means to perform stitch transfer work without mistakes.
Devices that forcefully open the latches of knitting needles have already been developed, and many have been put into practical use.

However, since the latch is easily damaged when the latch is forcibly opened, there has been a desire to improve this device. On both sides of a groove provided along the length of the needle stem on the back of the needle stem, slopes that slope upward from the top of the needle stem to the base are formed, and one side of the groove is opened at the end of the groove. An upwardly sloped notch is formed from the section to the front of the needle shaft, and during stitch transfer, the needle head of the needle on the side to be transferred is guided by the groove, and then the hook of the needle is guided when moving up along the notch. comes into contact with the uphill slope,
There is a stitch transfer needle (Jikko 50-4837) whose hook opens as the needle moves. However, in such a needle, a vertical groove must be formed on the side of the needle shaft, and a needle head passage must be created for the needle head of the transfer side needle to escape when it enters the vertical groove. The uphill slope that guides the needle must be thoroughly polished, which greatly increases the manufacturing process.In addition, in use, the needle head on the transfer side must be inserted into the vertical groove, which prevents trouble during knitting. Occurrence is also possible. Therefore, there has been a desire in the industry to put a simple device into practical use.

The purpose of the present invention is to provide a knitting needle with a stitch transfer function that allows a good stitch transfer effect to be obtained with slight improvements to the knitting needle, in order to meet the demands of this industry.One embodiment of the present invention is described below. The explanation will be based on the drawings.

1 is a knitting needle of the present invention, which differs from conventional knitting needles for horizontal knitting machines in that a hook 3 and a latch 4 are provided at the tip of the needle stem 2, and a leaf spring 6 is provided on the side surface 5 of the needle stem 2. There is no place. The leaf spring 6 has a base 7 fixed to the side surface of the needle shaft by appropriate means, and a distal end 8 pressed against the side surface 5 of the needle shaft. A pin 9 for opening the latch is provided protruding from the needle shaft side portion 5 surrounded by the leaf spring. The pin 9 is press-formed at the same time as punching out the needle stem. 10 is a stepped portion.

The knitting needle of this invention is made as described above.
As shown in Figure 3, the front and rear needle beds F and B
is inserted into. Front and rear needle beds F, B
moves left and right in 1/2 pitch or other pitches,
She is now able to move her eyes.

Next, the manner of transferring stitches from the front needle bed needle 1 to the back needle bed needle 11 using the knitting needles of the present invention will be explained. In this case, the front needle bed F and the back needle bed B are arranged so that the needle 11 which receives the stitches of the needle 1 inserted into the front needle bed F can rise into the space 12 surrounded by the needle stem 2 and the leaf spring 6. Pretense is being made to determine the position.

When the stitch L knitted in the previous course moves up inside the front needle bed F as shown in FIG.
It takes 0.

In this state, when the needle 11 of the back needle bed B that receives the stitches rises as shown in FIG. void 1 surrounded by
Put it within 2. At this time, the hook 13 of the needle 11 and the pin 9 come into contact with each other, but since the tip of the hook 13 has a curved surface and both needles 1 and 11 have elasticity, the hook 13 and the pin 9 do not come into contact with each other. push each other away. As the needle 11 rises further, the engagement between the pin 9 and the hook 13 is released, the pin 9 enters the hook 13, and then the latch 14 of the needle 11 engages the pin 9 of the knitting needle 1.
It takes. At this time, when the knitting needle 1 starts to rise, the latch 14 is prevented from advancing by the pin 9, so that the latch 4 is opened as the knitting needle 1 rises (FIG. 6). As knitting needle 1 continues to rise,
The latch 14 of the needle 11 is further pushed open by the pin 9 of the needle 1 and completely opened, and the stitch L hanging on the stepped portion 10 of the knitting needle 1 is ready to be transferred to the opposite needle 11 (Fig. 7). .

When the knitting needles 1 that have been raised as described above then begin to descend, the stitch transfer is completed as shown in FIG. When the stitch transfer is completed in this manner, the needle 11 that has received the stitch is lowered and the latch 14 is closed as shown in FIG.

In the above embodiment, stitches are transferred from front needle bed F to back needle bed B, but by inserting transfer needles in both stitches, stitches are transferred from back needle bed B to front needle bed F. Of course it can be done.

As detailed above, the present invention has the following features:
Since it is formed with a protrusion that protrudes sideways to open the latch of the needle that receives the stitches during stitch transfer, the latch of the needle that rises during transfer comes into contact with the protrusion and the latch is reliably pushed open. It is possible to completely transfer the stitches without causing a situation where the loop cannot be transferred due to the latch not opening during transfer. In addition, damage to the knitting needles caused by the conventional special device for forcibly opening the latch can be easily prevented, and this also has the effect of eliminating stitch transfer errors. In addition, the needle of the present invention has a protrusion that protrudes sideways on the side of the needle stem for opening the latch, but this protrusion can be formed at the same time as punching out the needle stem using a press. Needles can be made without changing the needle manufacturing process at all.

In addition, in the case of the needle of this invention, when opening the latch, the protrusion comes into contact with the side of the latch to open the latch. Furthermore, there is little impact on the pin supporting the latch 4, and the needle will not be damaged.
