It is possible to reliably prevent 1c from rotating inadvertently. In addition, the stopper 30 and the shaft hole 33
A stopper mechanism is constituted by this.

As shown in Fig. 1, left and right side parts 1b, 1c
Notches 34 and 35 are formed at the outer ends of the needle bed 1, respectively, and are located in front of the central portion 1a when the needle bed 1 is folded. A handle cavity A is formed in. Therefore, the needle bed 1 can be carried by inserting the hand into the handle space A. In addition, as shown in FIGS. 2, 5, and 6, a mounting plate 37 is attached to the back surface of the left and right portions 1b, 1c approximately in the center thereof using four mounting screws 36, and the mounting plate 37 and the left and right portions Both sides part 1
A gap S is formed between the back surfaces of b and 1c. Furthermore, rubber legs 38 are attached to the outer surface of each mounting plate 37. When the needle bed 1 is used, the needle bed 1 connected in a straight line is placed on the table 39.
The needle bed 1 can be fixed to the table 39 by placing one end of a shear vise 40 on the table 39 and inserting one end of the sheath vise 40 into the gap S.

Next, the operation of the hand knitting machine configured as described above will be explained. Now, FIG. 1 shows the needle bed 1 in a folded state and in a state in which the left side portion 1b and the center portion 1a are connected in a straight line. First, when forming the knitted fabric K shown in FIG. 4 using this hand knitting machine, each divided portion 1a to 1c is arranged in a straight line with the hinge 15 in the front position As shown in FIG. 7, the locking protrusions 13 of the central portion 1a are engaged with the openings 14 of the left and right portions 1b, 1c, respectively. Then, when each hinge 15 is moved to the rear storage position shown by the chain line in FIG. The spring force of the locking member 25 locks and holds the hinge 15 in the retracted position. Further, as the hinge 15 moves, the hinge 1
As the front end portion having the pin 16c of No. 5 is recessed into the rear of the sinker 4, the engagement protrusion 22 on the other actuating plate 16b is inserted into the engagement recess of the engagement protrusion 13, as shown by the chain line in FIG. 13a, each divided portion 1a-1c is locked in a connected state. Further, the operating piece 23 is engaged with the recess 12a of the frame 12. Therefore, the respective divided portions 1a to 1c are reliably connected by the engagement between these two parts 23 and 12a and the engagement between the engagement protrusion 22 and the locking recess 13a.

Then, as shown in FIGS. 5 and 6, after fixing the needle bed 1 to the table 39 with a sheath vise 40,
The knitted fabric K can be formed by removing the cover 11 from the sinker 4 of each divided portion 1a to 1c, placing a carriage along the front and rear rails 8 and 6, and sliding the carriage appropriately. Can be done. In this case, as is clear from FIG. 4, the front end of the hinge 15 is recessed into the rear of the sinker 4 during knitting, so the pin 16c does not interfere with the knitted fabric K, and the knitted fabric K is never deformed.

On the other hand, when carrying the hand knitting machine during knitting of the knitted fabric K, the sinker 4 of each divided portion 1a to 1c is
The covering cover 11 is attached to the knitting needle 3 and the sinker 4
After preventing it from protruding further forward, table 3
Remove needle bed 1 from 9. And each hinge 15
When the operation plate 16b is moved to the front position shown by the solid line in FIGS. 1 to 4 using the operation piece 23,
The locking piece 25b of the locking member 25 engages with the locking groove 24b, and the spring force of the locking member 25 locks the hinge 15 in the forward position. 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 it 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 respective boundary parts, the knitted fabric K is not deformed in any way and the left and right side portions 1b are rotated. , 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 elongated hole 29, and the stopper 30 is moved to the operating position shown by the chain line in FIG. 8, the elastic engagement is released. Based on the spring force of the stopper 32b, the operating piece 32a of the stopper 30 is locked to the other step 29b, and the shaft 31 of the stopper 30 is moved to the right side 1.
It enters into the shaft hole 33 of c. Therefore, the left and right side portions 1b and 1c of the needle bed 1 in the folded state are connected to each other by the shaft portion 31 and the shaft hole 33, and it is possible to reliably prevent the side portions 1b and 1c from rotating inadvertently. . Further, in this embodiment, since the stopper 30 is integrally assembled with the left side portion 1b, there is no risk of losing the stopper 30.

Further, as shown in FIG. 1, when the needle bed 1 is in the folded state, the notches 34 and 35 of the left and right portions 1b and 1c are arranged to face each other, forming a handle cavity A. Therefore, the needle bed 1 can be carried by inserting the fingers into the space A.

Sometimes, the needle bed 1 is usually placed on the top surface of a table 39 and fixed by a sheath vise 40 as shown in FIG. 5, during knitting. As shown in FIG. 2, when placing the kotatsu on the top surface of the kotatsu table 41, there are times when it is not possible or desirable to use the shank vise 40. In this case, the needle bed 1 is held only by the friction between the rubber legs 38 of each mounting plate 37 and the top surface of the table, so this is especially true when excessive sliding resistance is applied to the carriage. There is a risk that the needle bed 1 may slip on the table. In order to prevent this, in this embodiment, a plurality of flexible net members 42 as shown in FIG. 12 are prepared. That is, the net member 42 is made by welding and connecting an elongated string-like core material 43 made of, for example, foamed resin to a square of about 1 cm square, and has a structure around the core material 43 that is highly elastic and has a large frictional resistance. It is constructed by cutting a piece coated with resin 44 into a size of 20 cm in length and 30 cm in width. As a result, as shown in FIG. 11, for example, the nets are connected between the lower surface of the needle bed 1 in contact with the upper surface of the kotatsu table 41, that is, the vicinity of the lower surface of each pair of left and right mounting plates 37, and the table 41. By placing the needle bed 1 with the members 42 interposed therebetween, the needle bed 1 is held firmly and stably by the large frictional resistance of the elastic force of each net member 42.

Therefore, even without using the shear vise 40, there is no risk of the needle bed 1 slipping on the table top surface, and the knitting work can be carried out with peace of mind. Moreover, as shown in FIG. 11, for example, when the table 41 is placed on the kotatsubutton 45, the net member 42 is also placed between the top surface of the kotatsubutton 45 and the table 41. By appropriately interposing the table 41, it is possible to reliably prevent the table 41 from slipping with respect to the vines 45, thereby making it possible to perform the knitting work in an even more stable state. In addition, as shown in FIG. 13, when the peripheral edge 41a of the kotatsu table 41 is formed slightly high, for example, as shown in the same figure, the rear part of the net member 42 may be bent and stacked vertically. By interposing the needle bed 1 in a stable state, the difference in level before and after the needle bed 1 can be corrected and the needle bed 1 can be maintained in a stable state.

Note that the present invention is not limited to the above-mentioned embodiments, and the configuration of each part can be arbitrarily changed without departing from the spirit of the present invention.

Effects As detailed above, the present invention divides the needle bed into three parts: a central part and left and right side parts that are respectively foldable with respect to the central part, and also allows the needle bed to be divided into three parts, the central part and the right and left side parts that are foldable respectively. A stopper mechanism is provided between the ends of the parts to prevent them from rotating from the folded state, and the stopper mechanism can be moved along the longitudinal direction of the needle bed to either the left or right end of the part. The needle bed is made up of a stopper member having a shaft supported by the stopper member, and a shaft hole provided at the end of the other side so that the shaft of the stopper member can be freely inserted and removed. can be folded,
This provides an excellent effect in that it is possible to reliably prevent the left and right side portions of the needle bed in the folded state from rotating inadvertently with a simple operation.
