Description

  The present invention relates to a bead assembly jig for assembling a belt-shaped bead piece into a cylindrical body and a bead toy set including the bead assembly jig.

  Conventionally, there are bead toys that produce patterns using beads. For example, beads toys that create patterns by fusing beads and fusing each other, and beads that create patterns by bonding beads to the adhesive surface There are toys.

  The applicant of the present application adheres adjacent beads to each other by making the surface of a substantially spherical resin bead wet by bringing the surface into contact with a liquid and dissolving the surface and activating the adhesive force by drying. The bead toy set which produces a pattern is proposed (for example, refer to patent documents 1). The present applicant has also proposed a bead holding tray that can be connected to each other for arranging the water-meltable substantially spherical beads, thereby producing a long and large bead pattern. (For example, refer to Patent Document 2).

In the production of bead picture patterns with the above-mentioned water-meltable beads, not only are the beads arranged in a plane, but a flat picture pattern is also produced, and a plurality of flat bead pieces are combined to wet-dry the contact portions between the pieces. By doing so, it is possible to produce a three-dimensional ornament by adhering each other. In addition, cylindrical and annular ornaments are manufactured by bonding both ends of a belt-shaped bead piece to each other. For example, a belt-shaped bead piece is brought into contact with an outer peripheral surface of a cylindrical mold or the like. It was manufactured by winding and fixing with string-like fasteners such as rubber bands, and then wet-drying both ends.

  However, when manufacturing a cylindrical or annular ornament by the above method, the ends are displaced from each other due to the force to open the both ends of the band-shaped bead piece, that is, the force to return to the band shape. There was something I couldn't do. As the diameter of the decorative article decreases, this force increases and it becomes difficult to manufacture, and there is a problem that even if it can be successfully bonded, the end bonded portion is bonded in an angular state.

  Further, when a long belt-like bead piece is created due to a dimensional error of the beads, the bead may not fit in a predetermined position due to accumulation of the dimensional error, and irregularities may be formed on the plane of the piece, which may impair the appearance.

  In view of such a problem, the present invention is excellent in aesthetics regardless of the bead assembly jig and the bead dimensional error, which can easily produce a bead decorative product in which strip-shaped bead pieces are assembled into a cylindrical body. It aims at providing the bead toy set provided with the said bead assembly jig for manufacturing a bead piece.

  The present invention is a bead assembly jig for assembling a belt-shaped bead piece in an annular shape, and has a cylindrical portion having an inner peripheral surface and extending in a cylindrical shape, and a plurality of ribs protruding from the inner peripheral surface of the cylindrical portion The rib projects from the vicinity of the upper end of the cylindrical portion to the vicinity of the lower end, and extends at a lower end of the rib substantially perpendicular to the inner peripheral surface.

  The bead assembly jig according to the present invention includes a bottom portion continuously extending from the inner peripheral surface of the lower end of the cylindrical portion, and a rib extending substantially perpendicular to the inner peripheral surface is positioned on the upper surface of the bottom portion.

  The rib thickness of the rib protruding from the inner peripheral surface is preferably the radius or diameter of the bead, and the rib width is preferably slightly longer than the radius or diameter of the bead, and the interval between the ribs is 30 ° to 180 °. It is preferable that

  Moreover, this invention is a bead toy set for manufacturing a bead ornament with a water-meltable resin bead, and includes the bead assembly jig, a bead holding tray, and an illustration sheet.

  It is preferable that an arbitrary strip-shaped pattern is drawn on the illustration sheet by a circular pattern, and the strip-shaped pattern is a pattern configured by thinning out a circular pattern at a predetermined location to provide a blank portion. It is preferable to provide a sheet on which a pattern is drawn.

  By inserting a belt-shaped bead piece made of water-meltable beads into the bead assembly jig of the present invention with both ends in contact with each other and wet-drying the contacted both ends with a belt, it is easy to decorate the beads of the cylindrical body. You can make goods.

  The bead assembly jig of the present invention includes a plurality of ribs on the inner peripheral surface, and the ribs extend on the upper surface of the bottom portion. Therefore, the belt-like bead piece inserted into the bead assembly jig becomes the inner periphery of the bead assembly jig. There is no direct contact between the surface and the bottom. Therefore, it is possible to prevent excess moisture from adhering to the beads and to promote drying.

  In addition, since the ribs are provided at intervals at which the band-shaped bead pieces do not contact the inner peripheral surface of the cylindrical part of the bead assembly jig, and the thickness of the ribs is smaller than the diameter of the beads, Auxiliary bead pieces can be inserted between the two, and adhesion between both ends of the belt-like bead pieces can be reinforced.

  Furthermore, since the bead toy set of the present invention includes a bead assembly jig, a bead holding tray, and an illustration sheet, an illustration sheet is laid under the bead holding tray, and a belt-like bead piece that matches the size of the bead assembly jig Can be easily created.

  In addition, since the illustration sheet has a belt-like pattern formed by decimating a circular pattern at a predetermined location, even if there is a dimensional error in the bead, the dimensional error is absorbed in the space portion where the bead is thinned out. Since it can be arranged at a predetermined position without any deviation, it is possible to manufacture a bead ornament excellent in aesthetics, and it is also easy to curve the belt-shaped bead piece in an annular shape. And if it is equipped with an illustration sheet that draws a plurality of small patterns, it is a beautiful small bead piece, and it is a beautiful annular bead ornament while reinforcing the connection at both ends of the belt-shaped bead piece Auxiliary bead pieces that can be manufactured can be manufactured together.

  A bead assembly jig according to the present invention includes a cylindrical portion having an inner peripheral surface and extending in a cylindrical shape, a bottom portion continuously extending from a lower end inner peripheral surface of the cylindrical portion, and an inner portion of the cylindrical portion. A plurality of ribs project from the vicinity of the upper end to the vicinity of the lower end of the peripheral surface and extend on the upper surface of the bottom at the lower end. The ribs are provided at intervals of 30 ° to 180 °, the rib thickness of the rib protruding from the inner peripheral surface is the radius or diameter of the bead, and the rib width of the rib is slightly smaller than the radius or diameter of the bead. It is considered to be a large length.

  Further, a bead toy set according to the present invention includes the bead assembly jig, a bead holding tray, and an illustration sheet, and the illustration sheet is formed by rounding a predetermined portion with a circular pattern to provide a blank portion. A belt-like pattern is drawn.

  Hereinafter, although one embodiment of the bead assembly jig and bead toy set of the present invention is described in detail with reference to drawings, the present invention is not limited to this embodiment at all.

  FIG. 1 is a perspective view of a bead assembly jig according to the present invention, and FIG. 2 is a central sectional elevation view of the bead assembly jig according to the present invention. FIG. 3 is a view showing a bead holding tray, and FIG. 4 is a view showing an illustration sheet. FIG. 5 is a perspective view of the bead piece. 6 and 7 are diagrams for explaining a manufacturing process of a cylindrical bead ornament. FIG. 8 is a perspective view of a bead ornament manufactured using the bead toy set according to the present invention.

  The bead assembly jig 1 of the present invention is for use when bonding both ends of a bead piece formed in a band shape to form a cylindrical body. As shown in FIG. 1, the bead assembly jig 1 includes a cylindrical portion 2 having an inner peripheral surface, a bottom portion 4 continuous to the lower end of the cylindrical portion 2, and an inner peripheral surface of the cylindrical portion 2. And a plurality of ribs 3 projecting from.

  The cylindrical portion 2 is a substantially circular cylindrical body, has an inner peripheral surface, and extends in a cylindrical shape by a predetermined height. The diameter of the cylindrical portion 2 can be appropriately changed depending on the diameter of the beads to be used and the size of the ornament to be manufactured. However, if the diameter of the cylindrical portion 2 is made too small, the beads are bent when the belt-shaped bead piece is bent. There is a possibility of bending at the bonding portion between them, and it is difficult to make the belt-shaped bead piece into a cylindrical body, which is not preferable. For example, when manufacturing a beaded ornament imitating a crown, the diameter of the cylindrical portion 2 is preferably about 5 cm to 20 cm, but may be a larger diameter. Also, when the diameter is large, it is difficult for an infant or a child to create, but enjoyment such as a sense of achievement at the time of completion can be increased.

  The bottom portion 4 extends continuously from the inner peripheral surface of the lower end of the tubular portion 2 and closes the lower end side of the tubular portion 2. The bottom portion 4 is configured so that excess water out of the water used when bonding both end portions of the belt-shaped bead piece is dropped and not scattered outside the jig.

  The rib 3 includes a peripheral rib 3a protruding from the upper end to the lower end of the inner peripheral surface of the cylindrical portion 2, and the upper surface of the bottom portion 4 from the lower end of the peripheral rib 3a to the inner peripheral surface of the cylindrical portion 2. The bottom rib 3b extends substantially vertically, and is formed in a substantially L shape in side view as shown in FIGS.

  The peripheral rib 3a supports the outer peripheral surface of the strip-shaped bead piece, and provides a space between the inner peripheral surface of the tubular portion 2 and the strip-shaped bead piece so that an auxiliary bead piece described later can be inserted. The rib thickness d of the peripheral rib 3a is about the radius or diameter of the bead, and the rib width w is a length slightly larger than the approximate radius or diameter of the bead. When the rib thickness d is smaller than the bead radius, it is not preferable because a sufficient space for inserting the auxiliary bead piece cannot be provided, and when the rib thickness d is larger than the diameter of the bead, the auxiliary bead piece is This is not preferable because it cannot be sandwiched between the inner peripheral surface of 2 and the belt-like bead piece. Further, if the rib width w is shorter than the approximate radius of the beads, the rib 3 is not preferable because the bonded portion is broken or the support stability is deteriorated when the rib 3 comes into contact with the bonded portion between the beads. If the diameter is too larger than the diameter of the beads, the number of beads that come into contact with the ribs 3 increases, and excess moisture may accumulate, resulting in a resin bottle and the appearance may be impaired.

  The bottom rib 3b is provided to prevent the lowermost bead of the belt-shaped bead piece from coming into direct contact with the bottom 4. The height h of the bottom rib 3b is a desired height, and the rib width w is approximately equal to or slightly larger than the diameter of the bead. This is because the bottom rib 3b is configured to support at least one bead in order to stably support the strip-shaped bead piece. In addition, when the bottom of the belt-shaped bead piece has a wave pattern, the rib width w may be set to several beads. The rib length L extends longer than the radius of the bead and reliably supports the bead.

  In the bead assembly jig 1 of this embodiment shown in FIG. 1 and FIG. 2, the peripheral rib 3a and the bottom rib 3b have the same rib width w, and a length slightly larger than the radius or diameter of the beads. It is composed.

  A plurality of the ribs 3 are provided, and when the belt-like bead piece is bent so that both ends thereof are in contact with each other and inserted into the bead assembly jig 1, the belt-like bead piece is formed on the inner peripheral surface of the cylindrical portion 2. Provide at intervals that do not contact. In the present invention, the number of ribs 3 and the installation interval may be appropriately adjusted according to the diameter of the cylindrical portion 2, and the angle between the ribs is a plurality of 30 ° to 180 °, preferably about 30 ° to 120 °. If the arrangement is three or more, the lower end of the belt-shaped bead piece can be stably held. The bead assembly jig 1 shown in FIG. 1 is configured by arranging six ribs 3 at equal intervals, but may be arranged at different intervals.

  Therefore, when the band-shaped bead piece is inserted into the bead assembly jig 1, the band-shaped bead piece comes into contact with the peripheral rib 3a protruding from the cylindrical part 2 on the outer peripheral surface, and the lowermost bead is the upper surface of the bottom part 4. Will come into contact with the bottom rib 3b. Since the rib width w of the bottom rib 3b is approximately equal to or slightly larger than the diameter of the beads, at least one bead is placed on each bottom rib 3b, and the belt-shaped bead piece is It becomes possible to hold stably.

  When using water-meltable resin beads for the production of this beaded product, a liquid such as water is used for bonding the beads, but if the amount of liquid applied is too large, the amount of bead melted will increase and dissolve in water. The adhesive component that comes out becomes a cocoon and adheres to the beads, which may impair the beauty. Therefore, it is preferable to remove excess moisture, and since the bottom rib 3b extends on the bottom 4 of the bead assembly jig 1, a space is created between the bead piece and the bottom 4, and the excess moisture is removed from the bottom. 4 can be dropped.

  Further, since the peripheral rib 3a protrudes also from the cylindrical portion 2 of the bead assembly jig 1, the inserted belt-shaped bead piece is supported only by the beads contacting the peripheral rib 3a to form a cylindrical body. Therefore, a space is formed between the belt-shaped bead piece and the inner peripheral surface of the cylindrical part 2, and excess water adhering to the beads located in the space is dropped downward, or the auxiliary made with beads in the space A bead piece can be inserted to reinforce the adhesion between the ends of the belt-like bead piece or to decorate it.

  The bead assembly jig 1 can be made of a material capable of shape processing such as synthetic resin, ceramic material, wood, metal, etc., for example, by injection molding synthetic resin or vacuum forming synthetic resin thin plate It can be produced as an integral molding.

  In order to manufacture a three-dimensional cylindrical bead ornament using the bead assembly jig 1 of the present invention, first, a belt-shaped bead piece 7 is prepared. For the production of the band-shaped bead piece 7, a water-meltable bead 71, a bead holding tray 5 on which the beads 71 are arranged, and an illustration sheet 6 depicting the pattern of the band-shaped bead piece 7 are used.

  The beads 71 are substantially spherical resin beads whose surface is dissolved by contact with a liquid and whose adhesive force is activated by drying, and are colored with various colors.

  The bead holding tray 5 is transparent or translucent so that the illustration sheet 6 is visible. As shown in FIG. 3, the bead holding tray 5 is a substantially square resin thin plate having a desired thickness, and depressions 51 for arranging beads 71 are regularly formed on the entire surface. . The depressions 51 form depression rows, and adjacent depression rows are shifted in the row direction by a half pitch so that the placed beads are in contact with each other. The recess 51 is formed in a substantially hemispherical shape, and the opening diameter of the recess 51 is smaller than the diameter of the bead 71 so that the bead 71 is supported only by the upper peripheral edge of the recess 51.

  The first side wall of the bead holding tray 5 and the second side wall perpendicular to the first side wall are provided with locking projections 52, and the third side wall and the second side wall facing the first side wall are provided. A locking recess (not shown) that engages with the locking projection 52 is formed on the inner side of the fourth side wall that faces the bead, and the bead holding trays 5 can be connected to each other.

  In the illustration sheet 6, various patterns are drawn on the upper surface by a round pattern 61 having a diameter substantially equal to the diameter of the bead 71. In FIG. 4 (a), a long belt-like pattern 62 for creating the belt-like bead piece 7 is drawn, and its length is substantially the same as the circumference of the rib surface of the bead assembly jig 1. Are of equal length. Further, the belt-like symbol 62 is provided so as to repeat the blank portion 64 by thinning out a circular pattern at a predetermined portion of the intermediate portion so that the beads 71 are not concentrated in the belt-like bead piece 7. The circular patterns 61 at both ends of the belt-shaped pattern 62 are configured to be combined with each other.

  Further, an illustration sheet 6 for creating a small bead piece as shown in FIG. 4B may be provided. The small pattern 63 drawn on the illustration sheet 6 may be formed in a desired shape, but is formed in a size that can be inserted into the gap between the ribs of the bead assembly jig 1.

  A belt-like bead piece 7 and a small auxiliary bead piece 8 are created using the bead holding tray 5, the illustration sheet 6 and the beads 71, and a cylindrical bead ornament 10 is produced using the bead assembly jig 1 described above. To do. Hereinafter, a method for manufacturing the beaded ornament 10 will be described.

  First, the illustration sheet 6 is covered with the bead holding tray 5, and the beads 71 are placed on the bead holding tray 5 in accordance with the design of the illustration sheet 6. Next, the contact portion between the beads 71 is wetted with a spray or a brush. Then, it is allowed to stand until the water evaporates, and a belt-like bead piece 7 as shown in FIG. 5A and an auxiliary bead piece 8 as shown in FIG.

  Next, as shown in FIG. 6, the belt-shaped bead piece 7 is bent and the end beads 72 at both ends are brought into contact with each other and fitted into the bead assembly jig 1. To be located. Thereafter, the auxiliary bead piece 8 is inserted into the space between the ribs where the end beads 72 of the band-shaped bead piece 7 are located. At this time, as shown in FIG. 7 (a) and FIG. 7 (b), the belt-like bead piece 7 is arranged in contact with the peripheral rib 3a at the outer peripheral surface and supported by the bottom rib 3b at the lower end, The bead piece 8 is disposed in a space between the strip-shaped bead piece 7 and the cylindrical portion 2 of the bead assembly jig 1 and between the ribs where the contact end beads 72 are located.

  As shown in FIG. 5 (a), the band-shaped bead piece has a space in the middle part of the piece, so that the belt-like bead piece has a beautiful appearance alongside a smooth plane and bends with a small force. Can be easily done.

  Next, moisture is applied to the portion where both ends of the belt-shaped bead piece 7 are in contact with the auxiliary bead piece 8 by spraying or the like, and left to dry. At this time, the belt-like bead piece 7 exerts a force to open outward at both ends, but the force is suppressed from the outside by the cylindrical portion 2 and the auxiliary bead piece 8 of the bead assembly jig 1, and accordingly, The end beads 72 at both ends of the band-shaped bead piece 7 are bonded together without being detached, and the auxiliary bead piece 8 is also bonded securely, and the bonded portion is reinforced.
