Description

  The present invention relates to a knitting machine and a kit for knitting an elastic band.

  In recent years, knitting machines for knitting elastic bands such as rubber bands have been developed as toys for girls. The knitting machine has, for example, a base and a pin bar that can be detached from the base. In this knitting machine, knitted products such as bracelets can be made by hanging a plurality of elastic bands on the pins of the pin bar and knitting the elastic bands by using hooks to replace them with other pins or detach them from the pins. (See Patent Document 1).

  The pin for hanging the elastic band of the knitting machine described above is formed in a cylindrical shape, and a groove for accessing the hook is formed on one side surface thereof. This access groove makes it easy to remove the tensioned elastic band from the pin.

  The present invention will be specifically described below. In addition, the following embodiment is an illustration for demonstrating this invention, and this invention is not limited only to the embodiment. The same reference numerals are assigned to the same elements, and duplicate descriptions are omitted. In the drawings, positional relationships such as up, down, left, and right are based on the positional relationships shown in the drawings unless otherwise specified. Furthermore, the dimensional ratios in the drawings are not limited to the illustrated ratios.

  FIG. 1 is a perspective view showing an example of a knitting machine 1 according to the present embodiment. The knitting machine 1 includes, for example, a flat base 10 and a plurality of banding portions 11 erected side by side on the base 10. The knitting machine 1 is made of resin, for example, and is integrally formed by, for example, injection molding.

  The base 10 is formed in a substantially rectangular shape, for example, and a plurality of banding portions 11 are arranged in a straight line along the longitudinal direction of the base 10 (X direction in FIG. 1). A plurality of rows, for example, three rows are provided in the width direction of the base 10 (Y direction in FIG. 1). The number of the banding portions 11 in each row is the same, and the banding portions 11 in the middle row of the three rows are shifted so as to be staggered in the longitudinal direction from the banding portions 11 in the rows at both ends. The banding portions 11 in the rows at both ends are provided at the same position in the longitudinal direction.

  Each banding part 11 has a plurality of, for example, three column parts 20 as shown in FIGS. Each column 20 has a cylindrical shape with a small diameter, and extends vertically upward from the surface of the base 10. For example, as shown in FIG. 3, the column portions 20 are arranged at equal intervals on the same circumference C as seen from the plane. That is, the column part 20 is provided every 120 degrees of the circumference C. Therefore, as shown in FIG. 2, a large opening 25 is formed between the adjacent column portions 20.

  As shown in FIGS. 1 to 3, each banding portion 11 includes an upper end connection portion 21 that connects upper end portions of the column portions 20. The top connection 21 extends radially from the center of the circumference C to the top of each column 20 and is connected to the top of the column 20 as viewed from above. The outer peripheral surface 21 a formed between the column portions 20 adjacent to the upper end connection portion 21 is curved so as to be recessed toward the center side (inner side) of the circumference C.

  Moreover, each banding part 11 is provided with the protrusion part 22 which protruded to the outer side of the circumference C from the upper end part of the pillar part 20, as shown in FIGS. Thereby, even if the elastic band hung on the column part 20 of the band hanging part 11 is likely to come off from above, it is possible to suppress the elastic band from being detached from the band hanging part 11.

  A step portion 30 higher than the surface of the base portion 10 is provided at the base of each column portion 20. The step portion 30 is located at least outside the column portion 20. Thereby, even if an elastic band is located in the lower part of the column part 20, since it is caught by the step part 30, an elastic band does not stick to the surface of the base 10. FIG.

  As shown in FIGS. 4 to 9, each side wall surface of the base 10 of the knitting machine 1 is provided with a connection mechanism 60 for connecting to the base 10 of another knitting machine 1. The coupling mechanism 60 includes, for example, a protruding portion 70 that protrudes outward from the side wall surface of the base 10 and a slit 71 formed on the side wall surface of the base 10. As shown in FIG. 10, the projecting portion 70 has, for example, a cylindrical portion 70 a on the tip side, and a constricted portion 70 b that connects the cylindrical portion 70 a and the side wall surface, and by inserting the constricted portion 70 b into the slit 71 from below, The bases 10 can be connected to each other.

  Specifically, as shown in FIG. 5, the long side wall surface 81 in the width direction of the base 10 is provided with two protrusions 70, and as shown in FIG. Two sets of slits 71a and slits 71b are formed. The slit 71 a is formed, for example, at a position facing the protruding portion 70 (the same position in the longitudinal direction), and the slit 71 b is formed at a position slightly shifted from the position facing the protruding portion 70.

  Thereby, the base 10 and the other base 10 can be selectively connected to two places shifted in the longitudinal direction. Further, as shown in FIG. 11, when the protruding portion 70 of the base 10 is connected to the slit 71 a of the other base 10, any four adjacent banding of the base 10 and the other base 10 The arrangement of the portions 11 becomes a square (for example, a dotted line portion in FIG. 11). That is, the banding portion 11 in the end row close to the other base 10 and the banding portion 11 in the end row of the other base 10 are arranged at the same position in the longitudinal direction. Thereby, for example, so-called tail knitting can be performed in which one or two of the typical knitting methods are knitted in a chain shape using the two or four banding portions 11.

  The side wall surface 80 and the side wall surface 81 in the width direction of the base 10 are formed in a corrugated shape, and a plurality of recesses 90 are formed. And when the protrusion part 70 of the base 10 is connected with the slit 71a of the other base 10, and the arrangement | sequence of the nearest four banding parts 11 becomes a square, the corrugated recessed part 90 overlaps, square shape A through hole 91 is formed at the center of the four banding portions 11. Accordingly, the knitted chain-like portion can be passed through the through hole 91 while knitting the elastic band with the four band hanging portions 11.

  Moreover, when the protrusion part 70 of the base 10 is connected with the slit 71b of the other base 10, the arrangement | sequence of the banding part 11 which combined the base 10 and the other base 10 as shown in FIG. Becomes uniform. That is, the arrangement of the banding portions 11 when the base 10 is used alone (vertical and horizontal arrangement and spacing) is the same as the arrangement of the banding portions 11 when the two bases 10 are combined. Thereby, the two bases 10 can be handled as one base, and an elastic band can be knitted in a wider area | region using more banding parts 11 than the time of the base 10 single.

  As shown in FIG. 7, two protruding portions 70 are provided on the short side wall surface 82 in the longitudinal direction of the base 10, and two slits 71 are formed on the opposite side wall surface 83 as shown in FIG. 8. Is formed. The protruding portion 70 and the slit 71 are formed at positions facing each other (the same position in the width direction), and the protruding portion 70 of the base 10 and the slit 71 of the other base 10 are fitted together and shown in FIG. Thus, the base 10 and the other base 10 can be connected in the longitudinal direction.

  As shown in FIG. 4, a convex portion 100 protruding in the longitudinal direction is formed at the center of the side wall surface 82, and a concave portion 101 recessed in the longitudinal direction is formed at the center of the side wall surface 83. The banding portion 11 in the middle row is located on a straight line connecting the convex portion 100 and the concave portion 101. And when the base 10 and the other base 10 are connected in the longitudinal direction, the convex part 100 and the concave part 101 are fitted, and the arrangement of the banding part 11 that the base 10 and the other base 10 are combined with each other. Becomes uniform. That is, the arrangement and distance of the banding portion 11 do not change even at the connecting portion between the base 10 and the other base 10. Therefore, the arrangement of the banding portions 11 of the base 10 can be increased in the vertical direction, and the elastic band can be knitted in a wider area.

  In the knitting machine 1 configured as described above, according to a desired knitted product, the elastic band B is hung on the band hanging portion 11 at a predetermined place in a predetermined order as shown in FIG. The knit is knitted by replacing or removing the elastic band B. At this time, for example, as shown in FIGS. 15 and 16, the hook 110 is inserted from above into the gap A formed inside the elastic band hung on the band hanging portion 11, and the elastic band B is hooked from the inside. Then, the hook 110 is pulled upward, pulled out from the band hanging portion 11 and hung on another predetermined band hanging portion 11. When all the knitting is finished, the series of elastic bands are removed from the knitting machine, and the ends of the series of elastic bands B are fastened with C-shaped clips 111 as shown in FIG.

  According to the present embodiment, each banding portion 11 connects a plurality of column portions 20 arranged at intervals on the same circumference C when viewed from the plane, and the upper end portions of the column portions 20. It has the upper end connection part 21 and the protrusion part 22 which protruded from the upper end part of the pillar part 20 to the outer side of the circumference C. As a result, the openings 25 are formed in a plurality of directions between the column portions 20, so that the hook 110 can access the elastic band B hung on the band hanging portion 11 from a plurality of directions. As a result, it is possible to realize the knitting machine 1 in which the elastic band B can be easily knitted, the elastic band B is difficult to cut, and the knitting method is not limited. Moreover, since the upper end connection part 21 connects the upper end part of each pillar part 20, even if the opening 25 is ensured largely using the thin pillar part 20, the intensity | strength of the banding part 11 is ensured. Therefore, even if a strong tension of the elastic band B is applied, the band hanging portion 11 is not damaged, and this also increases the degree of freedom of the knitting method.

  Since the upper end connection part 21 extends radially from the center of the circumference C to the upper end part of each pillar part 20 and is connected to the upper end part of the pillar part 20 when viewed from the plane, the pillar connection as shown in FIG. The upper part of the gap A formed inside the elastic band B hung on the portion 20 is opened, and the hook 110 can be easily accessed inside the elastic band B. As a result, the elastic band B can be easily hooked by the hook 110.

  Further, since the outer peripheral surface 21a formed between the adjacent column portions 20 of the upper end connection portion 21 is curved toward the center of the circumference C, the hook 110 can be more easily accessed to the elastic band B.

  Since the column parts 20 are three and are arranged at equal intervals on the same circumference C, the interval between the column parts 20 is 120 degrees, and large openings 25 having different directions are secured between the column parts 20. it can. Moreover, the structure of the banding part 11 can be simplified while ensuring the strength of the banding part 11.

  A step portion 30 higher than the upper surface of the base 10 is formed at least outside the circumference C at the base of the column portion 20. As a result, as shown in FIG. 18, even when the elastic band B is hung downward on the column portion 20, the elastic band B does not adhere to the base 10, and a gap is formed between the base 10 and the elastic band B. . As a result, the elastic band B is easily hooked by the hook 110.

  The base 10 is provided with a connection mechanism 60 for connecting to another base 10. Thereby, a more complicated knitting can be made using more banding portions 11.

  Since the connection mechanism 60 can connect the base 10 and the other base 10 side by side in the width direction and can be selectively connected to two positions shifted in the longitudinal direction of the base 10, the band hooking portion Eleven sequence variations can be increased. In the present embodiment, there are two selectable connection positions of the base 10, but there may be three or more.

  The connecting mechanism 60 is configured such that when the base 10 and the other base 10 are connected in the width direction, the arrangement of the banding portions 11 including the base 10 and the other base 10 becomes uniform. The base 10 can be connected to a position where the arrangement of arbitrary four banding portions 11 adjacent to the base 10 and the other base 10 becomes square. Thereby, it is possible to cope with both when it is desired to increase the arrangement of the banding portions 11 of the base 10 and when the rectangular arrangement of the banding portions 11 is desired. Since the rectangular arrangement of the banding portions 11 is suitable for a typical knitting method when knitting a bracelet or the like, the merit of making this arrangement is great.

  When the base 10 and the other base 10 are connected to a position where the four banding portions 11 are square, the base is so formed that a through hole 91 is formed at the center of the four banding portions 11. Concave portions 90 are formed in the ten long side wall surfaces 80 and 81. As a result, it is possible to pass through the through-hole 91 a portion that has become long after finishing knitting during operations such as tail knitting. Therefore, the ease of knitting can be improved.

  The connecting mechanism 60 can connect the base 10 and the other base 10 side by side in the longitudinal direction, and the short side wall surfaces 82 and 83 of the base 10 have a convex portion 100 protruding in the longitudinal direction and the longitudinal direction. A recess 101 that is recessed is formed, and the protrusion 10 and the recess 101 of the base 10 and the other base 10 can be fitted. And when the base 10 is connected with the other base 10, the arrangement | sequence of the banding part 11 which the base 10 and the other base 10 match | combined becomes uniform. Therefore, the arrangement of the banding portions 11 of the base 10 can be increased in the longitudinal direction. In addition, in this Embodiment, although it was the example which connected the two bases 10, 3 or more can also be connected in the width direction and a longitudinal direction.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, the number of the column parts 20 of the banding part 11 described in the above embodiment is three, but is not limited thereto, and may be two, four, or five or more. May be. Moreover, the shape of the upper end connection part 21 and the protrusion part 22 can also be selected arbitrarily. The number and arrangement of the banding portions 11 on the base 10 are not limited to this. Moreover, since the connection mechanism 60 should just be able to connect the bases 10 to each other, it may be one using another known connection technique. The elastic band includes those other than rubber bands as long as they are elastic and annular.

  INDUSTRIAL APPLICABILITY The present invention is useful for realizing a knitting machine that is easy to knit an elastic band, is difficult to cut the elastic band, and has no limitation on the knitting method.
