DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A knitted fabric with a hole according to embodiments 1 to 3 of the present invention will be hereinafter described. A flat knitting machine used for the knitting is a two-bed flat knitting machine including a pair of front and back needle beds, and performs knitting using every other needles. Although not illustrated, a hole can be formed in a cardigan serving as a tubular knitted fabric. An empty needle may not be set and successive knitting needles may be used to perform the knitting in the case of a single layer knitted fabric. The flat knitting machine also includes a plurality of yarn feeders on the upper side of the needle beds, where the back needle bed is capable of being racked with respect to the front needle bed. The knitted fabric to be knitted is assumed to be entirely made of plain stitches, and the number of needles shown in the knitting diagram is less than that in the actual knitting for the sake of convenience of explanation. The knitted fabric may, of course, be knitted using structures other than plain stitches. Holes 3, 13, 23 shown in the present embodiment are buttonholes, but may be applied as holes for inserting a belt, a string-like fashion item, or the like.
The knitting diagrams of Figs. 2 to 4, and Fig. 6, to be described later, are shown with the following contents. "S(T) + number" in the left column in the drawing indicates a step number. A to S in the right column in the drawing indicate knitting needles of a front needle bed (hereinafter referred to as FB) and a to s indicate knitting needles of a back needle bed (hereinafter referred to as BB), ○ indicates an old stitch, • indicates a new stitch knitted in each step, ⊙ indicates double stitches, and V-letter indicates a pickup stitch or a tuck stitch, where the portion subjected to the knitting operation in each knitting step is shown with a solid line. Furthermore, the arrow in the left and right direction in the middle column in the drawing indicates a knitting direction, the arrow in the up, down, and diagonal direction indicates performing transfer, and the operation on the lower side in the plane of drawing is carried out first. With respect to the arrow in which up, down, and diagonal directions are combined, the steps in the middle are omitted.
Fig. 1 is a schematic diagram of a knitted fabric 1 with a hole 3 shown as embodiment 1. The knitted fabric 1 with the hole 3 of the present embodiment is knitted in a direction shown with an arrow from the lower side to the upper side in the drawing. A hole forming portion 1a branched from a side end portion 5 on the right side of the knitted fabric 1 is projected out to the exterior of the knitted fabric and then folded back. The hole forming portion 1a formed by a stitch row including at least one or more wales has the wale directions of the stitches opposing with the hole 3 in between as reverse directions. Other than at the hole 3, a starting end 8 and a terminating end 9 of the hole forming portion 1a that oppose each other are joined with a pickup stitch, to become a widening stitch, at a stitch. The widening stitch may be a pickup stitch or a stitch formed by split knitting or twist knitting. The hole forming portion 1a is folded back and joined at a plurality of areas, so that the force is distributed and the strength is increased even when the pulling force is applied on the hole 3.
The hole forming portion 1a shown in Fig. 1 has a shape projecting out to the exterior of the knitted fabric as a great number of stitches is knitted alone while the knitting of the stitches other than of the hole forming portion 1a is in pause, as shown with the number of arrows. The hole forming portion 1a is folded back near the middle in the wale direction, and the hole 3 has a shape of being sandwiched by the hole forming portion 1a formed with the stitch row including at least one or more wales.
The knitting steps of the knitted fabric 1 will now be described with the knitting diagrams of Figs. 2 to 4. In the drawing, the position of the side end portion 5 of the knitted fabric 1 is shown with a solid line. In the steps of S1 to S6, to be described later, the stitch row of before forming the starting end 8 of the hole forming portion 1a by flechage knitting is inclined so that the bend of the stitch row to be formed continuously is made smooth to suppress the protrusions of the stitches. S0 in Fig. 2 shows the knitting of a knitted fabric 1b of before forming the starting end 8 of the hole forming portion 1a, where stitches are formed on the knitting needles K, I, G, E, C, A of the FB.
In S1, a yarn feeder is moved in the rightward direction in the plane of drawing, and stitches are formed on the knitting needles A, C, E, G of the FB. In S2, a tuck stitch is formed on the knitting needle K of the FB, and stitches are formed on the knitting needles I, G, E, C, A. In S3, stitches are formed on the knitting needles A, C, E of the FB. Furthermore, in S4, the tuck stitch is formed on the knitting needle I of the FB and the stitches are formed on the knitting needles G, E, C, A in the leftward direction. After performing the knitting similar to S3 and S4 one time each, the stitch is formed on the knitting needle A of the FB in S5. Furthermore, in S6, a tuck stitch is formed on the knitting needle E of the FB and the stitches are formed on the knitting needles C, A in the leftward direction.
An inclined portion 7a in which the stitches are gradually reduced through steps S1 to S6 is shown in the knitted fabric 1 of Fig. 1. Although not shown in the knitting diagram, an inclined portion 7b is formed through flechage knitting in the knitted fabric 1 after forming the terminating end 9 of the hole forming portion 1a. The inclined portion 7b in which the stitches are gradually increased (after S21 to be described later) is formed symmetric to the inclined portion 7a. Similar to the inclined portion 7a, the inclined portion 7b makes the bend of the stitch rows to be formed continuously smooth to suppress the protrusions of the stitches.
In S7 of Fig. 3, the stitches are formed on the knitting needles A, C, E, G, I, and K of the FB. A stitch is also formed on the tuck stitch formed from S2 in this knitting. In S8, the stitches held on the knitting needles G, K of the FB are transferred to the knitting needles g, k of the BB, and then the stitches are formed on the knitting needles k, g of the BB and the knitting needle E of the FB in the leftward direction. After S8, the knitting of the knitted fabric 1b excluding the hole forming portion 1a is paused near the side end portion 5 of the knitted fabric 1, and the knitting of the hole forming portion 1a alone is continued. In S9, the tuck stitch is formed on the knitting needle C of the FB and the stitches are formed on the knitting needles E, I. A tubular structure is formed in S8 and S9. In S7, the stitches are formed on the knitting needles C, E, G, I, K of the FB to form the hole forming portion 1a with the stitch row including a wale of five stitches, but merely needs to be one or more stitches and not limited to five stitches. If the number of stitches is few, three or more widening stitches, to be described later, are preferably formed to increase the strength.
In S10, the stitches held on the knitting needles E, I of the FB are transferred to the knitting needles G, K of the FB and the stitches held on the knitting needles g, k of the BB are transferred to the knitting needles i, m of the BB, and thereafter the stitches are formed on the knitting needles m, i of the BB and the knitting needle G of the FB in the leftward direction. In S11, a pickup stitch to become the widening stitch is formed on the knitting needle E of the FB on the side opposite to the moving direction in S10, and the stitches are formed on the knitting needles G, K for holding the moved stitches. The stitch row configuring the hole forming portion 1a is moved toward the lateral direction, and a pickup stitch is formed on an empty needle formed by the movement and a new stitch row is formed following the moved stitch row. Thereafter, the knitting of S10 and S11 is repeated two times, where S12 shows the state after the repeated knitting. In S12, a pickup stitch is formed on the knitting needle I of the FB and the stitches are formed on the knitting needles K, O. The pickup stitches formed from S11 become three widening stitches worth the number of movements. The widening stitch to form is not limited to three, and merely needs to be two or more. The force becomes more distributed and the strength becomes stronger as the number of widening stitches increases.
In S13, the stitches are formed on the knitting needles q, m of the BB. In S14, the stitches are formed on the knitting needles K, O of the FB. In the knitting of S13 and S14, the stitch row configuring the hole forming portion 1a is knitted. The strength is increased by forming the tubular structure, and a satisfactory appearance is also realized as it can be seen similarly from both sides. The size of the hole 3 is adjusted by the number of times to repeat the steps of S13 and S14, where the steps are repeated ten times herein. The hole 3 projecting out to the exterior of the knitted fabric from the side end portion 5 of the hole forming portion 1a is formed.
In S15 of Fig. 4, the stitches held on the knitting needles K, O of the FB are transferred to the knitting needles I, M of the FB, and the stitches held on the knitting needles m, q of the BB are transferred to the knitting needles k, o of the BB. The double stitches including the pickup stitch and the stitch are formed on the knitting needle I of the FB by such transfer. It is moved in the direction opposite to when the starting end 8 of the hole forming portion 1a is formed, and is joined with the starting end 8 of the hole forming portion 1a by the widening stitch while forming the terminating end 9 of the hole forming portion 1a. In S16, the stitches are formed on the knitting needles o, k of the BB and the knitting needle I of the FB in the leftward direction. One part of the starting end 8 and the terminating end 9 of the hole forming portion 1a are joined. In S17, the stitches are formed on the knitting needles I, M of the FB. The knitting similar to S15 to S17 is repeated one time, and the formation of the double stitches and the joining are performed.
In S18, the stitches held on the knitting needles G, K of the FB are transferred to the knitting needles E, I of the FB, and the stitches held on the knitting needles i, m of the BB are transferred to the knitting needles g, k of the BB. The double stitches including the pickup stitch and the stitch are formed on the knitting needle E of the FB. In S19, the stitches are formed on the knitting needles k, g of the BB and the knitting needle E of the FB in the leftward direction. In S20, the stitches are formed on the knitting needles E, I of the FB. In S21, the stitches held on the knitting needles g, k of the BB are transferred to the knitting needles G, K of the FB, and thereafter the stitches are formed on the knitting needles K, I, G, E, C, A of the FB.
In S10 to S12, the starting end 8 of the hole forming portion 1a is formed. The stitch row configuring the hole forming portion 1a forms the widening stitch and the stitch while moving toward the lateral direction to the exterior side of the knitted fabric of the side end portion 5 of the knitted fabric 1. The stitch row of the peripheral edge portion of the hole 3 is formed by repeating S13 and S14. Furthermore, in S15 to S20, the hole forming portion 1a is folded back, and the movement and the knitting toward the interior of the knitted fabric are repeated. The hole forming portion 1a is returned to the original position while forming the terminating end 9, and the terminating end 9 is joined with the starting end 8 to form the hole 3.

The stitches held on the knitting needles A, C indicate the knitted fabric 10a, the stitches held on the knitting needles E, G, I, K indicate the hole forming portion 11a, and the stitches held on the knitting needles M, O, Q indicate the knitted fabric 10b. In T2, the stitches held on the knitting needles E, G, I, K of the FB are transferred to the knitting needles G, I, K, M of the FB, and then new stitches are formed on the knitting needles Q, O, M, K, I, G of the FB and a pickup stitch is formed on the knitting needle E, which became an empty needle.
Similar to T2, in T3, the stitches held on the knitting needles G, I, K, M of the FB configuring the hole forming portion 11a are transferred to the knitting needles I, K, M, O of the FB, and then a pickup stitch is formed on the knitting needle G of the FB, which became an empty needle, and stitches are formed on the knitting needles I, K, M, O. Furthermore, the knitting similar to T3 is repeated two times, so that one part of the hole forming portion 11a projects outside from the side end portion 15. The hole 13 without the projection from the knitting fabric 10 is formed if such repetition is not carried out or carried out once. The hole forming portion 11a may be set further on the interior side. In T4, the stitches are formed on the knitting needles S, Q, O, M of the FB, and in T5, the stitches are formed on the knitting needles M, O, Q, S of the FB. The size of the buttonhole 13 is adjusted with the number of times to repeat steps of T4 and T5. In the present embodiment, the number of times to repeat the steps is ten, but may be changed in accordance with the thickness of the yarn or the loop length.
In T6, the stitches held on the knitting needles M, O, Q, S of the FB configuring the hole forming portion 11a are transferred to the knitting needles K, M, O, Q of the FB, and then the stitches are formed on the knitting needles Q, O, M, K of the FB. The double stitches of the knitting needle K formed in the transfer is resolved, and the starting end 18 and the terminating end 19 of the hole forming portion 11a are joined. In T7, the pickup stitch is formed on the knitting needle p of the BB and the stitches are formed on the knitting needles O, M, K, I of the FB to form the stitches following the knitted fabric 10c. In T8, the knitting similar to T7 is repeated two times, and the stitches are formed on the knitting needles K, I, G, E, C, A of the FB. In T9, the pickup stitches held on the knitting needles 1, n, p of the BB are transferred to the knitting needles M, O, Q of the FB, and then the stitches are formed on the knitting needles A, C, E, G, I, K, M, O, Q of the FB. Among them, the stitches held on the knitting needles M, O, Q become the starting stitches 17 of the knitted fabric 10c.
