Description

[Detailed description of the invention] The present invention is designed to engage with the tip of a latch that is slightly inclined backward or to stand up the retracting knitting needles at the front upper part of the needle bed, and to rotate the latch forward toward the hook. This invention relates to an improvement in a needle bed for a hand knitting machine, which is provided with a latch engaging member that allows the needle bed to be lowered further backward.

Conventionally, there are needle beds of this type as shown in FIGS. 5 and 6. That is, a latch engaging member B made of a synthetic resin material and constructed on a band plate is fixed to the front upper vertical surface of a well-known movable sinker type hand knitting machine needle bed A, and the latch engaging member B is fixed to the front upper vertical surface of the well-known movable sinker type hand knitting machine needle bed A. Beforehand, engage the latch D with the latch engaging member B so that the tip of the latch D, which is slightly inclined backward, does not come into contact with the front edge of the groove plate E of the needle bed A. The latch D is rotated to the front hook side or further laid down to the rear, and the latch D is connected to the groove plate E.
It is designed so that it does not come into direct contact with the front edge of the

However, in this conventional method, especially the sixth
As shown in the figure, when the tip of the latch D of the knitting needle C engages the horizontal lower edge B ₁ of the latch engaging member B, _the latch D often
its lower edge without being separated upwardly or downwardly by
_B1 , which may deform or damage the lower edge _B1 or damage the latch D, thus impairing the latch release function of the latch engaging member B. There was a drawback of losing it early.

However, in order to eliminate the above-mentioned drawbacks of the conventional art, the present invention has a structure in which the lower edge of the latch engaging member that engages with the tip of the latch is extended in the left and right direction, and one of the left and right sides thereof is high. The latch has an inclined edge that is inclined so that the other end is lower, and when the tip of the latch comes into contact with the lower edge of the latch engaging member, the tip of the latch is moved upward by the inclined edge. In order to be able to handle it extremely smoothly and reliably, both downward and downward.
This is what I did.

A first embodiment embodying the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a needle bed of a so-called moving sinker type hand knitting machine, which is composed of an upper groove plate 2, a lower groove plate 3, etc. that are connected to each other. The lower groove plate 3 has a front vertical portion 3 thereof.
A vertically long front support hole 3B through which the stems of a large number of knitting needles 4 are individually inserted and supported is provided, and a lower butt guide groove 3c through which the butts of each knitting needle 4 are individually guided and inserted in the front-rear direction is provided in the intermediate horizontal part. An intermediate support portion 3D that supports the intermediate portion of each knitting needle 4 is provided, and furthermore, a rear support hole 3E is provided in the rear vertical portion for inserting and supporting the shank of each knitting needle 4 separately. The upper groove plate 2 is provided with a front horizontal part 2A and a front vertical part 2B on its front side, and an upper butt guide groove 2C in the middle horizontal part for guiding and inserting the butt of each knitting needle 4 in the front-rear direction. provided.

In the figure, reference numeral 5 denotes a swinging sinker that is separately arranged between the front portions of the knitting needles 4, the upper end of which rotates around a shaft 6 horizontally installed on the lower surface of the front horizontal portion 2A of the upper groove plate 2. As is well known, the knitting needle 4 cooperates with the back and forth sliding of the knitting needle 4 to participate in stitch knitting. Reference numeral 7 denotes an operating rod for rotating each of the swinging sinkers 5 separately, the front end of which is connected to each swinging sinker 5, and the middle part of which is inserted into and supported by the front vertical part 3A of the lower groove plate 3. At the same time, the butt is inserted into a guide groove (not shown) in the intermediate horizontal portion of the upper and lower groove plates 2 and 3 so as to be movable within a certain range in the front and back.

In the figure, reference numeral 8 denotes a latch engagement member composed of a metal flat plate member long in the left-right direction, and its lower band plate portion is fixed to the front surface of the front vertical portion 3A of the lower groove plate 3 by screws 9. As shown in FIG. 2, on the upper side of the knitting needles 4, there are provided a large number of substantially dogleg-shaped protrusions 10 that protrude upwardly from the knitting needles 4 at the same pitch as the rows of the knitting needles 4, and each of the protrusions An inclined edge 10A is formed at the upper lower edge of the piece 10, extending in the left-right direction across the upper part of the knitting needles 4, and inclined at a rather steep angle so that the left side is higher and the right side is lower. The upper side of each of the projecting pieces 10 covers the upper part of the support hole 3B corresponding to the upper side of the knitting needle 4 and the lower front surface of the front vertical part 2B.

A carriage (not shown) is installed on the upper surface of the needle bed 1 so as to be able to slide from side to side, and on the lower surface of the carriage, there is a well-known operation that operates the knitting needles 4 and the butts of the operating rod 7 in relation to each other when knitting a stitch. A cam (not shown) is provided, and a yarn opening (not shown) for supplying knitting yarn to the knitting needles 4 is provided on the front side.

This embodiment is configured as described above.

Therefore, by retracting the knitting needle 4 from the front and rear middle knitting preparation position shown in FIG. When engaged with the front surface of the protruding piece 10 of the latch engaging member 8,
The latch 4A is laid down on the front hook side (first
In addition, when the tip of a latch 4A similar to the above comes into contact with the inclined edge 10A of the protruding piece 10, the tip of the latch 4A is moved upward by the inclined cam action of the inclined edge 10A. The latch 4A is smoothly and securely released either downwardly or
is rotated to the front hook side or further laid down to the rear (as shown by the two-dot chain line in FIG. 1), and does not come into direct contact with the upper and lower groove plates 2 and 3.

A second embodiment embodying the present invention will be described below with reference to FIG.

This embodiment has the same structure as the first embodiment except for the latch engaging member, so a description thereof will be omitted, and the latch engaging member will be specifically explained.

That is, in the figure, reference numeral 11 denotes a latch engaging member constituted by a metal flat plate member long in the left-right direction, the upper part of which is fixed to the front surface of the front vertical part 2B of the upper groove plate 2 with a screw 12. , the lower edge of the lower edge corresponding to each knitting needle 4 has an inclined edge extending in the left-right direction by being cut out in a substantially V-shape, and inclined at a rather steep angle so that the left side is high and the right side is low. 13 is formed.

The inclined edge 13 of the latch engaging member 11 configured as described above
The releasing action of the latch 4A is the same as in the first embodiment.

The materials for the latch engaging members 8 and 11 include not only metal plates as described above, but also materials such as synthetic resin plates (having a hardness that does not hinder the release of the latch 4A with the inclined edges 10A and 13). Furthermore, the angle of inclination of the inclined edges 10A, 13 may be made steeper or gentler (however, angles close to vertical or horizontal are not preferred); In addition to being linear as in each of the above embodiments, it may also be arcuate with a large radius.

〓〓〓〓〓
As described in detail above, the present invention is such that the latch engaging member, particularly the lower edge that engages with the tip of the latch, is extended in the left and right direction, and one of the left and right sides is high and the other is resistive. Therefore, when the retreating knitting needle stands up or the tip of the latch, which is slightly tilted backwards, comes into contact with the inclined edge, the tip of the latch will contact the inclined cam of the inclined edge. As a result of this action, it is handled extremely smoothly and reliably either above or below the inclined edge. Therefore, it is possible to reliably avoid the drawbacks of the prior art described at the beginning, such as the tip of the latch digging into the lower edge of the latch engaging member and damaging the lower edge and the latch.
