Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a knitting needle used in a flat knitting machine equipped with a qualifying needle means and an electromagnetic needle selection means.
A knitting needle consists of a hook located at one end, a resilient and flexible shaft having a butt, and a sliding leg located at the end opposite the hook.

(Prior art) The above-mentioned knitting needles are described in, for example, German Published Patent Application No.
It is known from the prior art as described in No. 2315334 or No. 2559490. German Published Patent Publication No.
The knitting needles of No. 2315334 are two connected by a ball joint.
It consists of two parts, one of which is a tongue-like needle with a hook, the other part a flexible shaft with a hairpin-like support at the end opposite the ball joint, and a butt in the flexible part of this shaft. Become. The knitting needles of DE 25 29 490 A1 are formed as a single piece without flexible parts and are rotatably supported at the end opposite to the end with the hook.

(Problems to be Solved by the Invention) The object of the present invention is to have a butt that does not use a rotating joint or support, is flexible in the part that constitutes the butt, is rigid in the longitudinal direction, and is The object of the present invention is to provide a knitting needle of the above-mentioned type, which has suitable support means to ensure the stability of the guide in the knitting needle, and which is overall lightweight.

(Means for Solving the Problem) The above object is to provide an upper branch 6 provided as a shaft extending between the hook 12 and the butt 7, and a lower branch 6 provided parallel to the upper branch 6. It has a branch 9, said lower branch 9 being the needle groove 2 of the knitting machine.
It forms an extension of the sliding base of the knitting needle 3 located therein, and includes the hook 12, the upper branch 6, the butt 7,
The parts of the sliding leg 8 and the lower branch 9 are solved by the knitting needle according to the invention, which is formed as a single piece.

(Example) Hereinafter, an example of a knitting needle according to the present invention will be described with reference to the accompanying drawings. The accompanying drawing is a side sectional view of a needle bed incorporating knitting needles according to the invention.

In the figure, needle bed 1 indicates one of the needle beds in a flat knitting machine. A typical flat knitting machine has two needle beds, which are paired in a roof shape or an inverted "V" shape.
combined into glyphs. The needle bed 1 has a large number of needle grooves 2 parallel to each other, and in these needle grooves, a knitting needle 3, a two-arm lever 4, and a tack selector 5 are arranged. The knitting needle 3 has two branches, of which the upper branch 6 has a butt 7 and a leg 8, and the lower branch 9 forms the base of the knitting needle 3. The needle groove 2 becomes deeper toward the rear of the needle bed, that is, toward the right in the figure, and two sliding surfaces 10 and 11 are formed. The branch 9 slides on the sliding surface 10, and the leg 8 slides on the sliding surface 11. The knitting needle 3 also has a hook 12 and an engaging part 13. The lower branch 9 has the function of supporting the knitting needle well when the knitting needle 3 is at the most pulled out position from the needle groove 2, that is, the stitch transfer position, and also functions as a braking element for the knitting needle in the needle groove. also works. In this embodiment, when the knitting needles 3 move, the branch 9
moves while crossing the brake spring 14. This brake spring is for knitting needle cover band 1.
5 is arranged in a groove 16 provided in the needle bed 1 perpendicularly to the needle groove 2, a part of which intersects with the branch 9 in the needle groove 2. Although not shown, there is also a branch 9 as a brake mechanism.
It is conceivable to use a braking effect caused by friction between the branch 6 and a partition plate that partitions the groove 2 by warping the branch 6 laterally.

The branch 9 also has the effect of increasing the mass of the knitting needle part between the butt 7 and the hook 12, thereby effectively reducing the vibrations that often occur in this part due to the impact of the butt 7. ing. In order to continuously preset the knitting needles in the lower operating state, it is sufficient to press the butt 7 into the needle groove 2 and pass the engagement part 13 under the wire 17.
The wire 17 holds the knitting needle in this state until it is manually returned to its original state.

The two-arm lever 4 is swingably provided on a shaft 18 that is fixed to the needle bed 1. This two-arm lever 4
has an upper lever 19 and a lower lever 20,
These levers 19, 20 have a forked shape, and the tack selector 5 is held between them.
The lower lever 20 is supported on the branch 6 of the knitting needle 3 between the leg 8 and the engagement part 13. Two-arm lever 4
has a feeler 21 on the opposite side of the fork with respect to the shaft 18. Limiting wire 22
is fixed to the needle bed 1, and defines one limit position of the two-arm lever.

The tack selector 5 is formed with a notch 23, which allows the tack selector to be set in four different positions relative to the two-arm lever by engaging one of the notches 23 with the setting leg 24 of the upper lever 19. position in one of the positions. The tack selector 5 has a butt 25 which is arranged to selectively cooperate with a fixed longitudinal cam as will be explained below.

The auxiliary needle bed 27 is provided on the needle bed 1 at the innermost position of the needle groove 2. The auxiliary needle bed 27 has a plurality of grooves 28, in which the lower Jacquard selector 29 slides while being vertically restrained by wires 30, 31 fixed to the auxiliary needle bed 27. The upper Jacquard selector 32 is swingably disposed on the lower Jacquard selector 29. Above the butt 7, a cam box (not shown) is connected to the individual needle beds 1.

As the cam box moves, a selection head, such as selection head 50, actuates the upper jacquard selector 32. When the lever 4 rotates about its axis 18 during operation, its end 55
is located below the end 56 of the lower jacquard selector 29.

After needle selection has taken place, the lever 4 moves to the upper branch 6.
attempts to return to the position shown under the action of The lower jacquard selector 29, with the corresponding upper jacquard selector 32 selected, acts at the end 56 on the end 55 of the lever 4.
