Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a hand knitting machine in which a needle bed is divided into a plurality of parts in the longitudinal direction so as to be foldable in a substantially horizontal plane.

Prior Art As for this type of hand knitting machine, the following was filed by the same applicant as this application. In order to compact the long needle bed and make it convenient to store and transport, the needle bed is divided into three parts, and a hinge is attached to the boundary between the adjacent divided parts so that the needle bed can be folded. This is what I did.
Then, so that the knitted fabric can be folded while still being hung on the knitting needles, the center of rotation of the hinge is arranged to protrude below the front edge of the sinker, and the two sides of the hinge are placed in a substantially horizontal plane so that the sinkers of each divided portion face each other. The divided parts are designed to be rotated.

However, when the center of rotation of the hinge is disposed in front of the sinker in this way, there is a problem in that the knitted fabric hung on the hook interferes with the hinge and becomes a hindrance to the formation of the knitted fabric.

Purpose of the Invention This invention was made in view of the above circumstances, and its purpose is not only to enable the needle bed to be folded while the knitted fabric is hung on the knitting needles, but also to enable the hinge to To provide a new hand knitting machine capable of smoothly performing knitting work without interfering with knitted fabric.

Example Hereinafter, a first example embodying this invention will be described as a first example.
This will be explained with reference to FIGS. The needle bed 1 made of synthetic resin is divided into three parts in the longitudinal direction, the central part 1a having a length of about half of the total length of the needle bed 1, and the right and left parts 1b, 1c of the needle bed 1. is set to be half the length of the central portion 1a.
A large number of needle grooves 2a extending in a direction perpendicular to the longitudinal direction of the needle bed 1 are formed in rows at a predetermined pitch in the groove plate 2 of the needle bed 1. As shown in FIG. Knitting needles 3 are housed so as to be movable back and forth.
A large number of sinkers 4 are integrally formed in a row on the front edge of the groove plate 2 so as to be located between the knitting needles 3.
Further, the boundaries between the central portion 1a and the left and right side portions 1b, 1c are set between adjacent needle grooves 2a, and the sinkers 4 disposed between the needle grooves 2a are provided on the side portions 1b, 1c, respectively. There is.
A rear rail 5 extending in the longitudinal direction is disposed on the upper rear edge of each divided portion 1a to 1c of the needle bed 1, and a rear rail 5 extending in the longitudinal direction is provided on the upper surface of each divided portion 1a to 1c of the needle bed 1 near the base end of each sinker 4. A front rail 6 extending parallel to the rear rail 5 is attached to the rear rail 5. A carriage 26 placed on the needle bed 1 is slid along both rails 5 and 6 in the longitudinal direction.

As shown in FIG. 4, a comb-shaped needle brake spring 7 is fixed between the front rail 6 and the upper surface of each divided portion 1a to 1c, and each knitting needle 3 is urged downward by each spring piece 7a. has been done. Furthermore, a frame 8 for a knit leader device is disposed at the rear of the central portion 1a of the needle bed 1.

As shown in FIGS. 1 and 2, a guide tube 9 extending in the left-right direction is fixed to the lower surface of the both side portions 1b and 1c, and a fixing rod 10 is inserted into the guide tube 9 from the outside. It is becoming more and more like this.
One end of the fixing rod 10 is formed with a male threaded portion 10a, and the other end is formed with an operating knob 10b. When the needle bed 1 is unfolded in a straight line, the fixing rod 10 is inserted into the guide tube 9, and the tip male thread part 1
The needle bed 1 can be fixed in the unfolded state by screwing the threads 0a into the female screw holes 11 formed on both end faces of the central portion 1a.

As shown in FIGS. 1 and 3, a holder 12 made of synthetic resin with a certain degree of elasticity and attached to the center of the upper surface of the central portion 1a of the needle bed 1 has a grip portion 12a on the lower surface of its proximal end, and Fitting protrusion 1 on the lower surface
2b, each has an engaging protrusion 12c on the top surface of the tip, and the fitting protrusion 12b and the engaging protrusion 12
A contact projection 12d is formed on the lower surface between the contact projection 12d and the contact projection 12d. When the needle bed 1 is folded, the holder 12 is removably installed on the upper center surface of the central portion 1a, and the grip portion 12a grips the rear rail 5, and the fitting protrusion 12b
is fitted into the fitting hole 6a formed in the front rail 6 by the elasticity of the holder 12 itself, and the engagement hole 13 formed at the tip of both side portions 1b, 1c of the engagement protrusion 12c are engaged by the weight of both side portions 1b and 1c. As a result, both side parts 1
b and 1c are held in a folded state. In addition,
At this time, the contact protrusion 12d contacts the upper surface of the sinker 4.

Next, the sinker mechanism will be explained. As shown in FIGS. 2 and 3, a pair of bearing plates 14 and 15 are protruded from both front ends of the central portion 1a and front boundary portions of both side portions 1b and 1c, respectively.
A support shaft 16 is supported between them. A stopper 15 is provided between the bearing plates 15 on both sides 1b and 1c.
a is integrally formed.

Each of the support shafts 16 has a lower hinge piece 1.
7 and 18 are rotatably supported, and the adjacent hinge pieces 17 and 18 are rotatably connected to each other by a shaft 19 at their tips. The lower hinge pieces 17, 18 and the shaft 19 constitute a pair of left and right lower hinges 20 that are rotatable in a vertical plane. Therefore, when the lower hinge 20 is placed in the horizontal position, the left and right side portions 1b,
1c can be arranged in a position where it rotates in a horizontal plane with respect to the central part 1a and is in a straight line with the central part 1a, and in a position where it is folded in parallel in front of the central part 1a. Further, when the lower hinge 20 is arranged in a horizontal position where it is used as a hinge, the axis S of the shaft 19 is located below the sinker 4 at the center portion 1a and the side portions 1a.
b, 1c, and the front-to-back distance M between the axis S and a line L passing perpendicularly through the front ends of the sinkers 4 is half the distance between each sinker 4. Therefore, the distance between the front ends of the sinkers 4 that face each other across the boundaries of each portion 1a, 1b, and 1c is
It remains constant no matter which position b and 1c are rotated. Further, as shown by the two-dot chain line in FIG. 3, when the lower hinge 20 is retracted to the downward hanging position and stored, the front end connecting portion including the shaft 19 is located behind the line L.

The stopper 15a engages with the upper surface of the lower hinge piece 18 when the lower hinge 20 is placed in a horizontal position, thereby preventing further upward rotation of the lower hinge 20. The lower hinge 20 also has a locking groove 17 formed at the base end of each hinge piece 17, 18.
a, 18a, central portion 1a and both side portions 1
b, 1c are elastically held in the horizontal use position and the downward storage position by engagement with a locking leaf spring 21 attached to the front surface.

Needle bed 1 at each division part 1a to 1c boundary part
The upper hinge 22 is removably installed on the top surface of the
The upper hinge pieces 23 and 24 are made of synthetic resin and have a certain degree of elasticity, and both hinge pieces 23 and 24 are made of synthetic resin and have a certain degree of elasticity.
and a shaft 25 rotatably connecting the tips of the two. The lower surfaces of both upper hinge pieces 23 and 24 have gripping portions 23a and 24a, and fitting protrusions 2, respectively.
3b, 24b and contact protrusions 23c, 24c are formed in this order from the base end side. The gripping portions 23a, 24a grip the rear rails 5 of the central portion 1a and both side portions 1b, 1c, respectively, and the fitting projections 23b, 24b engage the fitting projections 23b, 24b formed on the front rails 6 of the central portion 1a and both side portions 1b. Matching hole 6
b by the elasticity possessed by the hinge pieces 23 and 24, respectively, and the contact protrusions 23c and 24
c comes into contact with the upper surface of the sinker 4. Furthermore, the axis 25 of this upper hinge 22 is similar to that of the lower hinge 25 when the upper hinge 22 is mounted on the needle bed 1.
It is located on the same axis as the axis 19 of.

Now, FIGS. 3 and 4 show the folded state of the needle bed 1 in the hand knitting machine constructed as described above. In this state, one hinge piece 23 of the upper hinge 22 is attached to both ends of the central portion 1a, and the other hinge piece 24 is attached to the boundary between the left and right side portions 1b and 1c, respectively. Further, a holder 12 is attached to the center of the central portion 1a, and an engaging protrusion 1 at the tip of the holder 12
2c is engaged with the engagement holes 13 of both side portions 1b, 1c, and both side portions 1b, 1c are held in a folded state.

Next, in order to unfold from this folded state and put it into a knitting use state, slightly lift the ends near the engagement holes 13 of both side parts 1b, 1c so that the engagement protrusions 12c of both side parts 1b, 1c Engagement hole 1
Remove 3. Next, the axis 1 of both the upper and lower hinges 20, 22
Both side portions 1b and 1c are rotated toward the side surfaces of central portion 1a about 9 and 25, so that central portion 1a and both side portions 1b and 1c are aligned in a straight line. In this case, the central portion 1a and both side portions 1b and 1c are connected on both the upper and lower sides by the lower hinge 20 and the upper hinge 22, so that as a result, they are connected by a vertically long axis. Both side portions 1b and 1c can be rotated stably and smoothly.

After doing this, insert the fixing rod 10 into the guide tube 9 of both side parts 1b, 1c, screw the male threaded part 10a at the tip into the female threaded hole 11 of the central part 1a, and are fixed to each other. Also, the left and right upper hinges 22 and the front ends of the holder 12 are lifted against the elastic force, and the fitting protrusions 12b, 23b, 24b are removed from the fitting holes 6a, 6b of the front rail 6, and the rear rail 5 is removed. Remove it from above the needle bed 1 by sliding it along
The left and right lower hinges 20 are retracted and rotated to the lower storage position.

Therefore, knitting can be carried out by attaching the carriage 26 onto the needle bed 1 and sliding the needle bed 1 in this state. In this case, since the lower hinge 20 is placed in the lower retracted position and its tip connecting portion is located behind the front edge of the sinker 4, the knitted fabric K and the lower hinge 20 do not interfere with each other. The lower hinge 20 does not interfere with knitting.

Next, in order to fold the needle bed 1 again, both fixing rods 10 are pulled out from the guide tube 9 and the female threaded hole 11, and before releasing the fixation between the central portion 1a and both side portions 1b, 1c, One hinge piece 23 of the hinge 22 is attached to both ends of the upper surface of the central portion 1a, and the other hinge piece 24 is attached to both side portions 1b, 1.
Further, the retainer 12 is attached to the central portion 1a, and the lower hinge 20 is pivoted to the horizontal use position. In this way, the axis 1 of both the upper and lower hinges 20, 22
Since the axes of 9 and 25 coincide in front of the front edge of the sinker 4, by subsequently removing the fixing rod 10, both sides 1b and 1c can be stably rotated in a horizontal plane, 1b, 1c can be folded in front of the central portion 1a. In this case, the shafts 19 of the upper and lower hinges 20, 22 relative to the sinker 4,
25, both side parts 1b, 1
Even if c is rotated, the distance between the tips of the sinkers 4 that face each other across the boundaries of each part 1a, 1b, and 1c is maintained constant, so that both parts 1b, 1c can be moved while the fabric K is hung on the knitting needle 3. Even if 1c is rotated, the stitches of the knitted fabric K do not widen, and there is no need to remove the knitted fabric K from the knitting needles 3.

After folding the left and right side parts 1b, 1c in this way, the engagement holes of the both side parts 1b, 1c are connected to the engagement protrusion 12c of the holder 12 which has already been attached to the center part of the center part 1a. If you slightly lift the end near 13 and engage it, both side parts 1b, 1
c is fixed in the folded state, and the entire needle bed 1 is compactly assembled. Therefore, it is convenient to transport or store the needle bed 1 in a case.

Next, a second embodiment of the present invention will be described based on FIGS. 5 to 9. In this second embodiment, shafts 31,
32 are arranged. A holder 12 (which does not need to have elasticity in this embodiment) is rotatably supported on the central shaft 31 in a shaft cylindrical portion 33 formed at the rear end.
It is rotated between a position along the upper surface of the central portion 1a as shown in the figure and a position lying backward as shown in FIG. Further, hinge pieces 23 of left and right upper hinges 22 (in this embodiment, like the holder 12, they do not need to have elasticity) are attached to the shafts 32 of both ends of the central portion 1a and both side portions 1b, 1c. It is rotatably supported by a shaft cylinder portion 34 formed at its base end, and both upper hinges 2
The needle bed 2 is rotated between a position along the upper surface of the central portion 1a and both side portions 1b and 1c and a position where the needle bed 1 is laid out in a straight line, and a position where the needle bed 1 lies backward.

As shown in FIGS. 8 and 9, the holder 12 and the upper hinge 22
It is elastically held in the two positions by the engagement between the locking grooves 33a, 34a formed at 3, 34 and the locking plate springs 35 attached to the central portion 1a and both side portions 1b, 1c. Further, as shown in FIGS. 5 and 7, receiving recesses 3 are provided at the center and both ends of the frame 8 for the knit leader device, respectively.
6 and 37 are formed, and their receiving recesses 3
6 and 37, the holder 12 and both upper hinges 22, which are disposed in the rearward lying position, are fitted and received.

Therefore, in this second embodiment, when the needle bed 1 is used for knitting, the holder 12 and the upper hinge 22 are
It is only necessary to rotate the holder 12 and the upper hinge 22 rearward so that the holder 12 and the upper hinge 22 are received in the receiving recesses 36 and 37, and there is no risk of losing the holder 12 and the upper hinge 22. In addition, in this second embodiment, when the upper hinge 22 is fitted into the receiving recess 37, both side portions 1b and 1c are locked unrotatably in the unfolded state, and the guide tube 9 and the guide tube 9 in the first embodiment are locked. Fixing rod 10 etc. are not required. In this second embodiment, a receiving recess 36 is formed in the center of the frame 8 for the knit leader device, and the holder 12 is fitted into the receiving recess 36, so that the receiving recess 36, Use one with a width narrower than the spacing between 37 and 37.

Next, a third embodiment of the present invention will be described with reference to FIGS. 10 and 11. In this third embodiment, a lock plate 42 is supported so as to be movable left and right by a pair of stepped screws 41 on both front sides of the central portion 1a and at the front boundary portions of both side portions 1b and 1c. (The lock plate 42 on the portion 1c side is not shown.) A bifurcated holding portion 42a is formed at one end of the lock plate 42. A knob 42b is formed on the lower edge of the lock plate 42 for moving the lock plate 42 left and right. This locking plate 42 has its clamping part 42a at a position where it is spaced apart from the lower hinge 20, and as is clear from FIG. It is operated to move between positions where it is clamped from the side, and is held at each position by appropriate clip locking means. Further, in this third embodiment, a stopper 14a for restricting the lower hinge 20 to the horizontal use position is also provided between the bearing plates 14 of the central portion 1a.

Therefore, in this third embodiment, when the lower hinge 20 is rotated to the horizontal use position in order to fold the both side portions 1b and 1c, each lock plate 42 is slid and the distal end clamping portion 42a is opened. If you hold each lower hinge piece 17, 18,
Each of the lower hinge pieces 17, 18 is locked in the horizontal use position, allowing both side portions 1b, 1c to rotate smoothly and stably. Further, even when the both side parts 1b, 1c are in the folded state, the lower hinge 20 is locked in the horizontal position, so that the both side parts 1b, 1c can be stably held. Therefore, the upper hinge 22 is not necessarily required in this third embodiment. Of course, when the needle bed 1 is put into knitting use, each lock plate 42 must be separated from the lower hinge pieces 17 and 18 in order to be able to rotate the lower hinge 20 to the rear storage position. Slide operation.

Next, a fourth embodiment of the present invention will be described with reference to FIG. In this fourth embodiment, unlike the first to third embodiments, the lower hinge 20 is retracted and rotated toward the upward standing position when the needle bed 1 is used for knitting. Therefore, stoppers 14a, 1 for holding the lower hinge 20 in the horizontal use position are provided.
5a is arranged to engage with the lower surface of each hinge piece 17, 18, and one of the locking grooves 17a, 18 for holding the lower hinge 20 in the storage position.
a is also provided at a different position from the first to third embodiments.

In the second to fourth embodiments described above, the needle bed 1 can be folded while the knitted fabric K is hung on the knitting needles 3, and the lower hinge 20 does not interfere with knitting, as in the first embodiment.

Note that the present invention is not limited to each of the embodiments described above, and the configurations of different embodiments may be combined or changed, for example, by providing the lock plate 42 even in the first embodiment. This does not depart from the spirit of the invention.

Effects of the Invention As exemplified in the embodiments above, the present invention provides a needle bed so that the hinge can be placed in a use position where the center of rotation corresponds to the vicinity of the front edge of the sinker, and a storage position where it is retracted to the rear of the hinge. By being rotatably attached to each part of the needle bed, the needle bed can be folded while the knitted fabric is hung on the knitting needles, and the lower hinge does not interfere with the knitting work, which is an excellent effect.
