and the rear stepped screw 41 are held.

When the operating body 46 is moved in the longitudinal direction of the needle bed 1 while gripping the grip portion 47 of the operating body 46, the hanging piece 50, the coiled spring 51,
The carriage 9 is moved integrally with the operating body 46 via a pair of stepped screws 40, 41, a support plate 42, a slide member 23, and a guide member 22. Thus, in this embodiment, the operating body 46 is used as an operating means for controlling the movement of the carriage 9. Further, when the operating body 46 is moved in the front-back direction, the mounting portion 48, the support pin 45,
The needle operating body 24 is connected to the operating body 4 via the swing lever 44, step screw 43, support plate 42, and slide member 23.
It is designed to move back and forth integrally with 6.

Next, the operation of the hand knitting machine constructed as described above will be explained with reference to FIGS. 7 to 10. First, as shown in FIGS. 7 and 8, move each knitting needle 8 to the front flattening position C1, C2 (subscript 1,
2 indicates the position of the butt and hook),
With the old stitch on each knitting needle 8 pulled out, hold the grip part 47 of the operating body 46, and hold the operating body 46.
For example, when the carriage 9 is moved in the direction of the arrow in FIG.
is moved integrally with the operating body 46. Then, with the movement of the carriage 9, the latch removal position
The butts 8a of the knitting needle groups C1 and C2 continue along the front edge of the island-shaped guide cam 19 and the inclined edge of the chevron-shaped guide cam 18 on the right side (front side in the carriage movement direction) in FIG. 8 to the center of the carriage 9. will be introduced. Thereafter, the butt 8a is moved to the island-shaped guide cam 19 on the left side (rear side in the carriage movement direction) in the figure.
The swing cam 36 is moved rearward along the inner inclined edge of the swing cam 36, and is sequentially engaged with the front edge of the swing cam 36 on the left in the figure, thereby switching and holding the swing cam 36 in the rear position. Then, the butt 8a escapes from the lower surface of the carriage 9 along the rear edge of the island-shaped guide cam 19 on the left side in the figure.
In this way, the knitting needle groups are arranged at the yarn feeding positions B1 and B2 shown in FIGS. 7 and 8.

Next, each knitting needle 8 placed at the yarn feeding position B1, B2
After passing the knitting yarn Y around the hook 8b, when the carriage 9 is moved in the direction of the arrow in Fig. 9 by reversing the direction of movement, the butt 8a of each knitting needle 8 will move to the left (forward in the carriage movement direction) in the figure. side) along the rear edge of the island-shaped guide cam 19 and the rear edge of the left swing cam 36 disposed at the front position, and its butt 8a is moved to the left (front side in the carriage movement direction).
By being sequentially engaged with the rear side edge of the movement regulating member 38, the movement regulating member 38 is switched and held as the non-restricting device shown in the figure. When the butt 8a of one knitting needle 8 at the end of the knitting section is placed opposite to the widened part of the first guide groove 21 due to the subsequent movement of the carriage 9, the right The protruding portion 37a of the movement regulating member 37 on the one side (rear side in the direction of carriage movement) hits the side surface of the butt 8a (this figure shows one in the middle of the knitting section).
The movement of the carriage 9 is regulated.

If the right movement regulating member 37 strongly collides with the side surface of the butt 8a during the movement restriction of the carriage 9, the movement of the right movement restricting member 37 is caused by the engagement between the hanging piece 50 and the coiled spring 51 shown in FIG. Coiled spring 51
One open end 51a of the carriage 9 is displaced forward in the direction of movement of the carriage 9 against its own spring force, and the pair of swing levers 44 are swinged in the same direction around the step screw 43. , the operating body 46 is slightly moved in the same direction. Therefore, the impact applied to the movement regulating member 37 can be absorbed, and damage to the movement regulating member 37 can be prevented. Furthermore, if the operator releases his/her hand from the operating body 46 after the operating body 46 has moved in the carriage movement direction, the spring force of the coiled spring 51 causes the operating body 46, the swing lever 44, etc. to return to their original positions. Moved back.

Now, with the butt 8a of one knitting needle 8 facing the expanded portion of the first guide groove 21, the operating body 46
As is clear from FIGS. 1 and 5, when the needle actuating body 24 is moved backward, the needle actuating body 24 is moved back via the mounting portion 48, the swing lever 44, the support plate 42, the slide member 23, and the like. And stitch adjustment dial 2
7, the abutting portion 24b of the needle actuating body 24 comes into contact with the stopper 30 on the gauge plate 29, which has been placed at a predetermined position, and the backward movement of the needle actuating body 24 is restricted. The actuating body 24 is arranged at the position indicated by the chain line in FIG.

Further, as the needle actuating body 24 moves backward, the engaging portion 24c engages with the butt 8a of the one knitting needle 8.
The butt 8a engages with the first and second guide grooves 2.
1 and 34, and the butts 8a and hooks 8b of the knitting needles 8 are placed at knockover positions A1 and A2 shown in FIGS. 9 and 7.

Then, one knitting needle 8 is at the knockover position.
When retracted to A1 and A2, the comb teeth 4 located on both sides of the knitting needle 8, especially the comb teeth 4 on the front side in the carriage sliding direction, are centered on the base end 4a based on the engagement with the knitting yarn Y. As a result, the open end portion 4c is slightly swung in the direction away from the knitting needle 8, and the distance between the comb teeth 4 is widened within the range R regulated by the stopper 5. In particular, the comb teeth 4 on the front side in the sliding direction of the carriage can be easily swung and the spacing between the comb teeth can be easily widened because the sinker loop of the course stitch has never been seen before. Therefore, in this example, thick knitting yarn Y is used,
Even if you knit the knotted part of a thread of normal thickness, the knitting thread will not stretch or the knot will be caught between the comb teeth 4 and the knitting needles 8, and the stitch L will be smoothly knitted. can be formed. Furthermore, unlike conventional needle beds that have a large number of comb teeth fixed at predetermined intervals, there is no need to set the comb tooth spacing widely to enable the use of thick knitting yarns, producing a compact needle bed. can do. These points are particularly effective for this stitch-by-stitch knitting.

Next, when the carriage 9 is moved together with the operating body 46 in the direction of the arrow in FIG. 9 with the needle operating body 24 positioned at the chain line position in FIG. 1 along the sloped edge
After the butt 8a of the actual knitting needle 8 is moved forward slightly, it is engaged with the rear edge of the gauge cam 33, and the stitch L of the size preset by the stitch adjustment dial 27 is formed.
is formed. At the same time, the one knitting needle 8
The butt 8a of the adjacent knitting needle is placed relative to the expanded portion of the first guide groove 21, and the right movement restricting member 37 placed in the restriction position hits the side surface of the butt 8a of the adjacent knitting needle 8 again. However, after the carriage 9 has been moved by the pitch of the knitting needles 8,
Its movement is regulated. In this state, when the operation body 46 is moved forward, as is clear from FIG.
The needle actuator 24 is rotated clockwise in FIG. 1 about the insertion hole of the base end 24a against the spring force of the leaf spring 25, and the needle actuator 24 is allowed to move forward. Then, the needle actuating body 24 is placed again at the solid line position in FIG. Then, as mentioned above,
If the operating body 46 is moved backward again, a new stitch L can be formed using the adjacent knitting needles 8.

In summary, after gripping the operating body 46 with the needle operating body 24 disposed in front and moving the carriage 9 in the direction of the arrow in FIG. 24 to move the knitting needles 8 back to the knock-over position, and in this state, the carriage 9 is again moved stepwise by one row of knitting needle pitches, and then the needle actuating body 24 is moved forward. Accordingly, one course of stitches L can be formed.

In addition, after forming one course of knitting yarn Y, the first
As shown in Figure 0, if the carriage 9 is moved in the direction of the arrow in the figure with the needle actuating body 24 placed at the rear position in the figure, the butt 8a of the knitting needle 8 placed near the knockover position A1 will be moved. is gauge cam 33
After being introduced to the lower surface of the carriage 9 along the rear edge, the butts 8a can be escaped from the lower surface of the carriage 9 without applying any knitting action to each knitting needle 8, and the carriage 9 can be moved to the lower surface of the carriage 9 in the knitting section. It can be placed in a predetermined position.

In addition, in this embodiment, each cam 18, 1
Like the movement regulating members 9, 20, 33, 35, and 36, the movement regulating members 37 and 38 are arranged symmetrically with respect to the needle actuating body 24, so that the carriage 9 is
When moved in the direction opposite to the arrow in the figure, the swing cam 35 on the right side in FIG. In Fig. 9, the movement regulating member 37 on the right side is switched to the non-limiting device, and the movement regulating member 38 on the left side is switched to the regulating position, and the butt 8a of each knitting needle 8 is retreated to the knockover position A1. Therefore, even when knitting is performed by sliding the carriage 9 in either the left or right direction, the movement of the carriage 9 can be reliably regulated at the position of one knitting needle 8 to be knitted, and a stitch can be reliably formed. can.

Effects As detailed above, the present invention can simplify the structure of the carriage and make it compact, and can reliably form a new stitch by directly operating the needle actuating body by manual operation. Instead, a pair of left and right movement regulating members are provided on both the left and right sides of the needle actuating body to restrict the movement of the carriage by engaging with the side surface of one knitting needle that is subjected to the action of the needle actuating body. When knitting by sliding in either the left or right direction, the movement of the carriage can be reliably regulated by the movement regulating member on either the left or right at a position where the needle operating body faces each knitting needle in sequence, A knitting operation can be reliably applied to each stitch. Furthermore, when both of the movement regulating members are located on the front side in the carriage sliding direction, they are avoided by engaging with the knitting needles to a non-restricting position where the movement of the carriage is not restricted, and are also located on the rear side in the carriage sliding direction. Since it is configured to engage with the side surface of the one knitting needle to restrict the sliding movement of the carriage, when the carriage slides in either the left or right direction, the movement restriction member on either the left or right side is engaged. always acts, and at that time, the other movement regulating member is in the avoidance position, does not have any influence on the sliding movement of the carriage, and does not interfere with the movement regulating action of the one movement regulating member. It has the excellent effect of not being
