Description

[Detailed description of the invention] This invention relates to the needle bed of hand knitting machines, and more specifically, during knitting, it is designed to reduce the bending moment that the knitting needles receive due to sliding within the needle bed, and to prevent damage to the knitting needles from bending. It is ivy. Hereinafter, a conventional needle bed will be explained with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a grooved plate, on the lower surface of which a front plate 2 and a rear plate 3 are fixed, and a large number of knitting needles 4 are arranged. Reference numeral 5 designates a lower plate that holds the comb teeth 6 between it and the front plate 2. The lower plate 5 includes a needle presser spring 7 made up of a number of protrusions 7a, and a needle guide plate 8 having a number of grooves 8a. It is fixed.

Therefore, each of the protruding pieces 7a of the needle presser spring is
It comes into contact with the lower surface of the shank of each knitting needle 4 and urges it upward.

Further, the groove 8a of the needle guide plate 8 engages with the shank of the knitting needle 4, as shown in the second figure, to prevent it from falling to the left or right.

Reference numeral 9 denotes a carriage with a cam member 10 provided on its lower surface, and the left and right movement of the carriage causes the knitting needles 4 to move back and forth within the needle bed via its butt. Since the back and forth movement of the knitting needles is performed from the transition of the slope of the cam member,
Naturally, a pushing and bending force acts on the knitting needle shank as shown by the chain line in FIG. In particular, if there are knots or the like in the knitting yarn during knitting, a large resistance is generated to the sliding of the knitting needles, and the knitting needles are bent by the cam, causing damage such as needle bending. This required interruption of work, replacement of knitting needles, etc., and was a major hindrance to knitting work.

In this invention, as a technical means to achieve the above object, the needle bed was constructed as follows. That is,
The rear plate on the lower surface of the groove plate is placed slightly forward (closer to the cam end of the carriage) than the conventional arrangement, and an auxiliary plate is provided behind it. The upper part of the needle groove provided on the auxiliary plate was bent horizontally to increase the contact area with the knitting needles. Therefore, in this configuration, the rear part of the butt of the knitting needle is locked at two locations in each of the needle grooves of the rear plate and the auxiliary plate, and the contact surface is brought into contact with the upper part of the needle groove of the large auxiliary plate. Furthermore, from the above configuration,
The needle guide plate provided in the conventional model has been abolished.

By configuring this invention in this way, it is possible to prevent the knitting needles from collapsing and bending, and to improve work efficiency through smooth needle sliding and light knitting operations. Since the needles are made larger, there is less wear and the height of the knitting needles can be maintained constant. Therefore, it is possible to prevent the occurrence of trouble between the knitting needle and the cam due to a change in the height of the knitting needle due to wear of the rear plate needle groove, which has been observed in the past.

Next, an embodiment of this invention will be described with reference to FIGS. 4 and 5. (In addition, the same numbers are attached to the same members as the previous model.) In Fig. 4, 11 is a rear plate, and the rear plate 11 is slightly forward on the lower surface of the groove plate 1 compared to the previous model (shown in Fig. 1). (closer to the cam).

Reference numeral 12 denotes an auxiliary plate, which is fixed to the groove plate 1 together with the rear plate 11 at the rear of the rear plate 11 (at the position of the previous rear plate). The auxiliary plate 12 is provided with a large number of needle grooves 12a corresponding to knitting needles, and the upper part of the needle groove 12a is bent horizontally 12b and has a width indicated by the symbol t. (Refer to Figures 4 and 5) As a result, the rear part of the knitting needle butt is supported between the two points T of the needle grooves of the rear plate 11 and the auxiliary plate 12, and the needle of the auxiliary plate is energized by the needle presser spring 7. It is pressed against the groove upper portion 12b portion t.

From the above explanation, the details of the means for achieving the purpose and effect of this invention will be clearly understood.
