Further, as the hinge 15 moves forward, its pin 16c is disposed directly below the front edge of the sinker 4, and as shown by the solid line in FIG. The locking protrusion 13 is disengaged from the locking recess 13a, and the locked state of each of the divided portions 1a to 1c is released. Then, the engagement protrusion 22 and the front edge of the protrusion 21 on one of the actuating plates 16a are engaged with the inner surfaces of the respective divided portions 1a to 1c, and the hinge 15 is not moved further forward than the forward position.

In this state, the left and right sides 1b and 1c of the needle bed 1
When the sinker 4 of the central portion 1a is rotated toward the front side of the sinker 4 of the central portion 1a about the pin 16c of each hinge 15, the left and right side portions 1b, 1c are rotated almost horizontally, and the connecting protrusion of the left portion 1b shown in FIG. 27 enters into the connecting hole 28 of the right side portion 1c, and the both side portions 1
b, 1c are connected, and displacement of both side portions 1b, 1c in the vertical direction is prevented. Further, the sinkers 4 on both the left and right portions 1b and 1c are arranged opposite to each other immediately in front of the sinker 4 on the central portion 1a, and the sinkers 4 on both the left and right portions 1b,
The hooks 3b of the knitting needles 3 on 1c are arranged close to each other and facing each other. That is, since the pin 16c is located directly below the front edge of the sinker 4, the hooks 3b of the knitting needles 3 located on both sides of the boundaries between the left and right portions 1b, 1c and the center portion 1a are spaced apart from each other. Since the knitted fabric K is rotated around the pin 16c in close proximity to each other, even if the stitches of the knitted fabric K that are being knitted straddle the boundary portions, the left and right side portions 1b, 1c can be folded.

After folding the needle bed 1, as shown by the solid line in FIG. 8, the stopper 30 disposed in the inactive position is operated by the operation piece 32a of the elastic locking piece 32b against the spring force of the elastic locking piece 32b. When the operating piece 32a is rotated counterclockwise to disengage from one step 29a of the long hole 29, and in this state the stopper 30 is moved to the operating position shown by the chain line in FIG. 8, the elastic piece Based on the spring force of 32b, the stopper 3

Mounting portions 53 for each support plate 18a, 18b formed on the back surface of each divided portion 1a to 1c and ribs located near the notches 52a, 52b so as to be located on both sides of each actuating plate 16a, 16b. 54, the central portion 1a and the left and right side portions 1
A pair of movable plates 55a and 55b are respectively supported on b and 1c so as to be movable in the longitudinal direction of the needle bed 1. Note that FIGS. 17, 18 to 21 are bottom views, and the left side portion 1b is shown on the right side of the center portion 1a. Each movable plate 55a, 55b has a recess 56 for loosely fitting each actuating plate 16a, 16b, a notch 52a of each actuating plate 16a, 16b,
52b, and a projection 57 which also serves as a spring hook is formed.

A locking member 25 is mounted at the center of a support pin 58 provided in each of the divided portions 1a to 1c on one side of each operating plate 16a, 16b, and one end of the locking member 25 is connected to a protrusion 57 of the movable plate 55a, 55b. The locking piece 25b at the other end can be engaged with each of the locking grooves 51. As shown in FIG. 17, when the hinge 15 is placed in the retracted position, the locking piece 25b is engaged with the locking groove 51 based on the spring force of the locking member 25, and each operation The locking member 25 is in a state where the notches 52a, 52b of the plates 16a, 16b are spaced backward from the protrusions 57 of the movable plates 55a, 55b.
The opposing ends of the movable plates 55a, 55b are held in a mutually engaged state by the spring force.

On the other hand, as shown in FIG. 18, when the hinge 15 is disposed at the front position, the locking piece 25b separates from the locking groove 51 and each operating plate 16a, 16b

Assuming that there is no looseness during assembly in each part of the hinge 15 in c, each divided part 1a
~1c are not arranged on the same plane as shown by the chain line in the same figure, but since there will be some looseness during assembly, especially at each part such as the shaft support of the pin 16c, Left and right side parts 1b, 1c
When the needle bed 1 is lowered by its own weight, it is arranged on the same plane as the central portion as shown by the arrow in the figure, and the flatness of the needle bed 1 is maintained. In other words, the connecting portions of the actuating plates 16a, 16b are twisted by an angle necessary to correct looseness during assembly.

Next, the configuration of the parts stand and parts box installed in the hand knitting machine in this embodiment will be explained in detail. As shown in FIGS. 11 to 15, the component stand 62 made of synthetic resin is formed in the shape of a prism with a bottom, and the hollow part 62a is formed into three triangular prism-shaped first to third accommodating parts 63a. Two ribs 64a and 64b are provided for partitioning into 63c.
One rib 64a is arranged on a plane that includes a pair of opposing ridgelines of the component stand 62, and the other rib 64b is arranged on a plane that is perpendicular to the one rib 64a and includes another ridgeline that is opposite to that rib 64a. It is located in And one rib 64
A and the side wall of the component stand 62 form a large-capacity first storage portion 63a, and both ribs 64
A, 64b and the side walls of the parts stand form second and third storage portions 63b, 63c of small capacity.

The first accommodating portion 63a can accommodate slightly wide components such as the pattern board 65 shown in FIG.
The second or third accommodating portions 63b, 63c are designed to accommodate elongated parts such as a tap 66 or a needle. As shown in FIGS. 12 and 13, an opening is provided near one ridgeline of the component stand 62 at the bottom of the component stand 62, and extends in the vertical direction of the component stand 62.
A mounting hole 6 with an almost L-shaped cross section and a separate chamber from 3c.
7 is formed. Inside this mounting hole 67, four protrusions 68 are formed at predetermined intervals on the side wall of the component stand, extending vertically in parallel.
As is clear from FIG. 11, in a state in which the divided portions 1a to 1c of the needle bed 1 are connected and arranged in a straight line, the parts are placed at one side 67a or the other side 67b of the mounting hole 67. 62 can be fitted to either one of the operating pieces 23 of the other operating plate 16b arranged in the storage position, and in this state, the component stand 62 can be placed close to either side of the frame 12. Can be held upright.

In particular, since the ribs 64a and 64b are used to divide the housing into a plurality of housing parts 63a to 63c, the Tatsupi 6 can be placed upright in each housing part.
6 and other parts are in a nearly upright state, and this prevents the parts from tilting too much and protruding into the surroundings, so there is no need to worry about, for example, the tatsupi 66 leaning too far forward and interfering with carriage operation. It is something.

Further, since the component stand 62 has a substantially flat bottom surface, it can be used by itself by being placed on the top surface of the table 39, etc.
A plurality of accommodating portions 63a are provided by the ribs 64a and 64b.
~ 63c, so the shock when parts such as Tatsupi 66 thrown into each storage part fall against the side wall is small, especially,
Since the ribs 64a and 64b are provided on a plane including each ridgeline, the shock when the component falls against the side wall is applied in the direction along the ribs 64a and 64b, that is, in the diagonal direction when viewed from above the component stand. Therefore, compared to, for example, the case where the component stand receives a shock in a direction parallel to each side wall, the component stand is less likely to fall because the arm of the moment in the diagonal direction is long. Therefore, when using the parts stand 62 by itself on the top surface of the table 39, etc.,
Even if parts such as the tapi 66 are thrown a little roughly, they will not fall over easily and will remain stable.

Next, a third embodiment of this invention is shown in FIGS. 22 to 29.
Referring to the drawings, a description will be given focusing on the differences from each of the embodiments described above. A tension spring 92 is hung between a spring hanging piece 90 protruding from the outer edge of the other actuating plate 16b and a pin 91 protruding from the lower surface of the left and right side portions 1b, 1c, and the spring force causes the hinge to 15 is urged to move rearward. In addition, in the bottom views of FIGS. 23 to 29, the left side portion 1b is shown at the right position in each figure. The locking protrusion 22 protruding from the other actuating plate 16b is formed in a cylindrical shape, and a notch recess 93 is formed in one side edge of the other actuating plate 16b. At the boundary between the left and right parts 1b, 1c and the center part 1a, the left and right parts 1

Further, an engaging portion 94a is formed at one end of the rotary lever 94, and a bent portion 94b is formed at the other end, and the bent portion 94b projects obliquely downward from the other actuating plate 16b. As shown in FIG. 23, when the hinge 15 is placed in the retracted position, the spring force of the tension coil spring 95 causes the engaging portion 94a of one end of the rotary lever 94 to engage with the inner edge of the other actuating plate 16b. When the hinge 15 is engaged and placed at the forward position as shown in FIG. be done. The cutout recess 93, the rotary lever 94, and the like constitute a locking means for locking the hinge 15 in the forward position.

A rotary member 97 is rotatably supported at one end of a support pin 96 protruding from approximately the center of the upper surface of one of the actuating plates 16a. The tension coil spring 9 is wound around the support pin 96 and
The rotating member 97 is urged to rotate in one direction by a spring 98 having a spring force stronger than 5, and is always pressed downward so as to come into close contact with the upper surface of the actuating plate 16a. The rotating member 9
7 has a bent portion 94b of the rotating lever 94.
An engaging protrusion 99 that can be engaged with the upper surface and the side edge of the lever 94 is formed protrudingly, and the rotating member 9
A substantially L-shaped elongated hole 100 is formed at the side edge of the center portion 7, and an engagement pin 101 protruding from the lower surface of the central portion 1a is loosely fitted into the elongated hole 100.
The engagement between the elongated hole 100 and the engagement pin 101 restricts the rotation range of the rotating member 97, especially when the engagement pin 101 engages with the rear bent portion of the elongated hole 100. When the hinge 15 is locked and held at the front position and moved rearward based on the spring force of the tension spring 92, the engagement pin 101 is engaged with one front end of the elongated hole 100. , the hinge 15 is held in the retracted position. The engagement pin 101, the rotating member 97, and the like constitute a locking means for locking the hinge 15 in the forward position.

Therefore, in a state in which the divided portions 1a to 1c of the needle bed 1 are arranged in a straight line and each hinge 15 is arranged in the retracted position based on the spring force of the tension spring 92, each of the above-mentioned embodiments Similarly, the locking protrusion 13 of the central portion 1a is connected to the left and right side portions 1b,
The other actuating plate 1 is inserted into the opening 14 of 1c.
The engaging projection 22 on the locking projection 6b is engaged with the locking recess 13a of the locking projection 13, and the divided portions 1a to 1c are locked in a connected state. In addition, the rotation lever 94
The engaging portion 94a is engaged with the inner edge of the other actuating plate 16b, and the elongated hole 10 is inserted into the engaging pin 101.
0 is engaged. In this state, a carriage is placed on the needle bed 1, and the knitted fabric K can be formed by operating the carriage. Further, the hinge 1
5 will not interfere with the knitted fabric K.

Then, in order to fold the needle bed 1, when each hinge 15 is operated to move forward against the spring force of the tension spring 92 using the operating piece 23 of the other operating plate 16b, as shown in FIG. Actuation plate 16b
The upper engagement protrusion 22 is in the engagement recess 13 of the engagement protrusion 13.
Leave from a. Further, when the notch recess 93 of the other actuating plate 16b faces the engaging portion 94a of the rotary lever 94 as the hinge 15 moves forward,
The rotating lever 94 is rotated in one direction based on the spring force of the tension coil spring 95, and the engaging portion 94a engages with the notch recess 93, so that the hinge 15 is locked and held in the forward position. Further, as the hinge 15 moves forward, the rotating member 97 is moved along the elongated hole 100 integrally with one of the actuating plates 16a, and the engaging protrusion 99 engages the bent portion 94b of the rotating lever 94. Engaged with the upper surface, the rear portion resists the downward elasticity of the spring 98 and is placed on the bending portion 94b in a state slightly raised above the upper surface of the actuating plate 16a.
When the bent portion of the other end of the elongated hole 100 faces the engagement pin 101, the rotating member 97 is rotated in one direction based on the spring force of the spring 98.

Thereafter, as shown in FIGS. 26 and 27, while the hinge 15 is held in the forward position by the pivot lever 94, the pin 16 of the hinge 15 is
The needle bed 1 can be folded by horizontally rotating both the left and right parts 1b and 1c in one direction about c, and the sinkers 4 of the left and right parts 1b and 1c and the hooks 3b of the knitting needles 3 face each other. will be placed. Therefore, as in each of the embodiments described above, the left and right side portions 1b, 1 can be separated without deforming the stitches of the knitted fabric K spanning the boundary portions of the divided portions 1a to 1c.
c can be folded.

On the other hand, when the needle bed 1 folded as described above is arranged in a straight line again, the pin 16c of the hinge 15 arranged at the front position is
When the left and right portions 1b and 1c are rotated back around , as shown in FIG. 28, the central portion 1
The locking protrusion 13 of a enters the opening 14 of the left and right side portions 1b and 1c, and is already lowered so as to come into close contact with the upper surface of the actuating plate 16a due to the downward elasticity of the spring 98 in the rotational position shown in FIG. The locking protrusion 99 of the rotating member 97 is engaged with one side edge of the rotating lever 94. After that, when the return rotation operation of the left and right side portions 1b, 1c is continued, the spring force of the spring 98 that holds the rotation member 97 in the position shown in FIG. 28 is stronger than the spring force of the tension coil spring 95, Then, the rotating lever 94 is rotated clockwise in FIG. 28 against the spring force of the tension coil spring 95, and its engaging portion 94a is disengaged from the notch recess 93 of the other actuating plate 16b. Then, when the rotary lever 94 rotates further and the inner edge on the one end engaging portion 94a side comes into contact with the side surface of the central portion 1a and further rotation is restricted, this time,
The rotating member 97 moves against the spring force of the spring 98.
It is rotated counterclockwise in the figure, the engagement between the rear bent portion of the elongated hole 100 and the engagement pin 101 is released, and the forward locked state of the hinge 15 is released. Then, when the left and right side portions 1b, 1c are brought into close contact with the center portion 1a and the actuating plates 16a, 16b are parallel to each other, the spring force of the tension spring 92 causes the hinge 1 to
5 is moved rearward, and as is clear from FIGS. 29 and 23, the engaging protrusion 22 on the other actuating plate 16b
enters into the locking recess 13a of the locking protrusion 13 and the respective divided portions 1a to 1c are automatically locked in the connected state, and the engaging pin 1 is inserted into one end of the elongated hole 100.
01 is engaged and each hinge 15 is placed in the retracted position. On the other hand, when the engaging protrusion 99 of the rotating lever 94 is removed from the other end bent portion 94b, the one end engaging portion 94 of the rotating lever 94 is moved by the spring force of the tension coil spring 95.
a returns to the position where it is in elastic contact with the inner edge of the actuating plate 16b, and the other end bent portion 94b can be engaged with the engagement protrusion 99 of the rotating member 97 shown in FIG. placed in a suitable position.

Note that in this embodiment, the settings of the spring forces of the spring 98 and the tension coil spring 95 are not limited to these; for example, the spring force of the tension coil spring 95 is set to be strong, and the rotation member 97
The width of the elongated hole 100 may be slightly larger than the engagement pin 101. In this case,
In FIG. 28, the engaging protrusion 99 is connected to the rotating lever 9.
28, the rotating member 97 is first rotated counterclockwise in FIG. It separates from the matching pin 101.

Then, when the rotating member 97 rotates further and the rotation is restricted by the edge of the elongated hole 100, the rotating lever 97 resists the spring force of the tension coil spring 95.
4 is rotated clockwise in FIG. 28, and its engaging portion 9
4a is removed from the notched recess 93 of the other actuating plate 16b, and the forward locking state of the hinge 15 is released. As the rotating member 97 moves rearward together with the hinge 15, the engaging protrusion 99
is rotated to the position shown in FIG. 23, which is opposite to the other end bent portion 94b of the rotary lever 94 (by the play between the engagement pin 101 and the elongated hole 100), and stands ready for engagement.

In addition, in the engagement relationship between the rotating lever 94 and the rotating member 97 in this embodiment, contrary to the above, the other end bent portion 94b side of the rotating lever 94 can be moved slightly up and down. Then, the other end bent portion 94b may be resiliently held at an upper position where it can come into contact with the engaging protrusion 99 of the rotating member 97 at all times.

It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, the lengths of the left and right sides may be changed as appropriate, or the hinge may be automatically locked in the forward position to simplify the configuration. Instead of a locking means,
For example, the configuration of each part may be freely modified without departing from the spirit of the present invention, such as configuring the movable plates 55a, 55b to be operated with fingers to lock the hinge in the forward position or release the lock. It is also possible to change to

Effects As detailed above, in this invention, the hinge is attached to the front position where the center of rotation corresponds to the vicinity of the front edge of the sinker, and the storage position recessed behind the hinge so that it can be freely retracted back and forth. This allows the needle bed to be folded while the knitted fabric is hung on the knitting needles with the hinge placed in the forward position, and prevents the hinge from getting in the way of the knitted fabric being knitted with the hinge placed in the retracted position. This has an excellent effect in that the organization work can be carried out smoothly without any problems.
