On the upper side of the support B, a large number of needle guide grooves 8 are arranged in rows at equal intervals in the left and right direction, for adjusting the positions of the needle stems and butts of the knitting needles 2 in the left and right directions, and supporting them so that they can be slidably inserted in the front and rear directions. be done. Guide pieces 9 whose height is very slightly shorter than the upper surface of the needle stem of the knitting needles 2 are provided on the left and right sides of the front extension of each needle guide groove 8, and between each knitting needle between the guide pieces 9, A recessed support portion 1 for receiving and locking the rear protruding piece 3A of the sinker 3 in the left and right direction in a normal size stitch formation.
0 is formed, and the support part 9 is formed at a position corresponding to each of the knitting needle sliding paths between each of the guide pieces 8.
The sinker 3 is formed in the same shape as the supporting portion 9 and has the same longitudinal and vertical arrangement positions as the sinker 3.
An auxiliary support portion 11 is formed to position and receive and lock the rear protrusion 3A in the left-right direction. Furthermore, each of the sinkers 3 is provided at the lower part of the front end corresponding to the sliding path of each of the knitting needles 2 and the front of each of the supports 10.
A receiving groove 12 is formed for receiving and locking the front protruding piece 3B by adjusting its position in the left-right direction.

In the figure, reference numeral 13 denotes a bullet plate whose base plate is fixed to the upper front part of the support body B by screws 14, and the bullet plate 13 has a bullet plate fixed to the front upper side of the support body B by a screw 14, and the bullet plate 13 is attached to a portion corresponding to each knitting needle 2 on the front side and each sinker 3 between the knitting needles. The knitting needle 2 has a width that is extremely slightly larger than the left and right width of the knitting needle 2 and the sinker 3.
A pressure contact piece 15 is provided in pressure contact with the upper side of the sinker 3 to provide appropriate resistance to sliding of the knitting needle 2 and to hold the sinker 3.

In the figure, reference numeral 16 denotes a front rail for a carriage, which will be described later, and is fixed to the support body B by the screws 14 while overlapping the upper surface of the base plate of the bullet plate 13. 17 is the rear rail for the carriage described later,
It is fixed to the upper rear side of the support body B. Before the above,
The inner opposing end surfaces 16A and 17A of each rear rail limit forward and backward movement by colliding with the butt of the knitting needle 2, and the distance between the two end surfaces 16A and 17A is equal to the butt of the knitting needle 2. The front end slide is set to be very slightly larger than the length between the front surface and the rear end of the needle stem, so that the front surface of the butt abuts against the opposite end surface 16A of the front rail 16, as shown in FIG. By placing the knitting needle 2 in the moving position and lifting the rear end of the needle stem of the knitting needle 2 upward (lifting it by holding the butt), the knitting needle 2 can be pulled out upward from the needle guide groove 8. Further, it can be inserted and supported by the reverse operation.

In the figure, reference numeral 18 denotes a switching plate capable of switching between a state in which each of the knitting needles 2 can be pulled out and a state in which the knitting needles 2 cannot be pulled out. It is held between the upward facing surface of A and is movable in a horizontal plane, and is fitted into substantially S-shaped cam holes 19 provided at at least two locations in the longitudinal direction and each of the cam holes 19. By means of the guide regulating means with the fixed guide pin 20 using a screw, the front edge fits into the slit groove 21 of the support body A as shown in FIGS. 1 and 2 and is within the sliding range of the knitting needle butt. The knitting needle 2 can be moved obliquely back and forth between a holding position where the needle 2 is prevented from coming off by being protruded and a non-holding position where the needle 2 can be pulled out by escaping rearward from the slit groove 21. The switching plate 18 is moved and operated by operation parts (not shown) protruding from the left and right outer sides of the needle bed 1, and is moved at both positions by appropriate locking means (not shown). It is designed to be locked separately.

In the figure, 22 is a carriage for knitting, and the front and rear sliding legs 2 slide on the front and rear rails 16 and 17.
3 and 24 so as to be slidable left and right, and on the lower surface thereof, there is a front bulkhead 25 for forming a front body needle passage A, and a pair of left and right knitting cams 26 for forming a knitting passage B. , a rotating cam 27 pivotally supported at the rear end of each knitting cam 26, and a rear partition wall 28 for forming a rear body needle passage C, and the knitting needles 2 A yarn opening 30 for supplying knitting yarn 29 to the hook is provided.

In addition, 31 in the figure is a reinforcing plate that is fitted and fixed in the groove 32 on the upper surface of the front side of the support body B, and is made of a steel plate or the like that is harder than the support body B, and corresponds to the position directly below each knitting needle 2. Prevent wear on the front upper part of support B.

This embodiment is configured as described above.

Therefore, when knitting ordinary sized stitches, the knitting needles 2 and sinkers 3 are arranged in the arrangement shown in FIG.

In addition, when knitting particularly large stitches using thick knitting yarn, etc., the switching plate 18 is placed in the non-holding position in advance as shown in FIG. (After pulling out a predetermined number of needles, the switching plate 18 is returned to the holding position), and the sinkers 3 on both the left and right sides of the knitting needles 2 to be pulled out are attached to their protrusions 3A,
It is removed by disengaging 3B from the support portion 10 and the receiving groove 12. Therefore, the auxiliary support part 11 and the receiving groove 1 corresponding to each of the knitting needles 2 that have been pulled out are
The sinker 3 is supported by engaging the projecting pieces 3A and 3B with the sinker 2, respectively. By the above operations, the arrangement of the knitting needles 2 and sinkers 3 becomes as shown in FIG. 3, and the arrangement pitch of the knitting needles 2 and sinkers 3 becomes twice that of the above.

In this arrangement, particularly large stitches can be knitted using thick knitting yarn or the like.

Furthermore, the arrangement pitch of knitting needles 2 and sinkers 3 was changed to 3.
It can also be easily changed to double or quadruple times.

A second embodiment embodying the present invention will be described below with reference to FIGS. 6 to 8.

In comparison with the first embodiment, this embodiment has a structure excluding the sinker and its support portion.
Since this embodiment is the same as that of the embodiment, its explanation will be omitted, and the sinker and its support will be particularly explained below.

In the figure, 33 is a sinker in the shape of a slightly thick round bar, and a recessed circumferential groove 34 is provided on the lower circumferential surface of the sinker.

On the other hand, the sinkers 33 are fitted and supported at the same angle at a position corresponding to the intermediate part between the knitting needles at the front end of the support body B and a position corresponding to the sliding path of each knitting needle 2. A support portion 35 and an auxiliary support portion 36 each having a circular concave shape are formed,
In addition, all the supporting parts 35 and auxiliary supporting parts 36
A circular groove 37 with a circular cross section is provided that penetrates in the left and right direction so as to communicate with each part of the . The elastic strip 38 is fitted, and elastically contacts the circumferential groove 34 of the sinker 33 fitted into the support part 35 and the auxiliary support part 36, and the sinker 33
Hold it so that it cannot be accidentally removed.

This embodiment is configured as described above.

Therefore, when knitting a normal size stitch, as shown in FIG.
It is sufficient to insert and support it.

On the other hand, when knitting particularly large stitches using thick knitting yarn, etc., the changeover plate 18 is moved and switched, and every other knitting needle 2 is pulled out. Pull out the sinkers 33 on both the left and right sides of the knitting needle 2 from the support part 35, and
Auxiliary support part 3 corresponding to each extracted knitting needle 2
6 to fit and support the sinker 33. As a result, as shown in FIG. 8, the knitting needles 2 and sinkers 33 are arranged every two pitches.

Furthermore, the arrangement pitch of knitting needles 2 and sinkers 3 was changed to 3.
It can also be easily changed to double or quadruple times.

As described in detail above, in the present invention, sinkers between each knitting needle are separately supported on a support part in a removable manner, and a sliding path of each knitting needle is provided on the front side of the needle bed separately from the support part. An auxiliary support part is provided to removably support the sinkers so that the sinkers can be arranged in correspondence with the sinkers.

Therefore, by supporting the sinkers on all of the support parts, it is possible to knit stitches of normal size, and also to support the sinkers on the auxiliary support parts after removing the knitting needles or to knit them at predetermined intervals. By supporting the knitting needles and sinkers on the support section, the arrangement pitch of the knitting needles and sinkers can be changed to twice, three times, or four times the normal case, and knitting of particularly large stitches using thick knitting yarn or the like can be carried out. In short, several types of knitting with different stitch sizes can be performed on one needle bed by attaching and detaching the same knitting needles and sinkers.
