Below, an embodiment of the present invention will be described with reference to the drawings. Figs. 1 and 2 are front and back perspective views of the holder 1 in this embodiment. The holder 1 is a member that holds a group 5A, 5B of a weldable bead toy 51, which will be described later in Fig. 7, via joint members 2, 3A (or joint members 3B, 4), enabling storage, display, and the like. In the following description of the holder 1, the surface 11a side of the main body 11 is referred to as the front, and the opposite side as the back. In addition, the first engaging piece 13a side of the main body 11 in the first direction X is referred to as the left, and the opposite side as the right, and the first engaging piece 13b side of the main body 11 in the second direction Y is referred to as the bottom, and the opposite side as the top.

The holder 1 has a main body 11 in the form of a rectangular plate. The main body 11 is formed in a substantially rectangular plate shape and has a substantially planar surface 11a (first surface). A plurality of rectangular concave and convex surfaces are formed on the surface 11a to form a checkerboard pattern. Any other pattern may be applied to the surface 11a by molding, coloring, or the like. A plurality of openings 111 (first engaged portions) arranged in a matrix of 7 rows and 6 columns are provided on the surface 11a side of the main body 11. The openings 111 are formed as round holes with bottoms (see also the cross-sectional view in FIG. 4(a)).

The side surfaces 12 (12a-12d) extend from the outer periphery of each of the four sides of the front surface 11a of the main body 11 toward the back surface 11b (second surface). The left side surface 12a and the lower surface 12c (first side surface) are formed with first engagement pieces 13a, 13b (13) that extend laterally via bases 131 (see Figures 2, 4(a) and 4(b)) on the back surface 11b side of the left side surface 12a and the lower surface 12c, respectively. The first engagement pieces 13a on the left side surface 12a side are provided in three locations. The first engagement pieces 13b on the lower surface 12c side are provided in two locations. The first engagement pieces 13a on the left side surface 12a are formed narrower than the first engagement pieces 13b on the lower surface 12c.

Of the multiple spaced apart first engagement pieces 13a, 13b, the first engagement pieces 13a, 13b located at both ends are provided on the end side of each side surface 12a, 12c (i.e., the corner side of the main body portion 11 in FIG. 3). In FIG. 3, the outer edges 13a1, 13a2 of the first engagement piece 13a on the left side surface 12a side are provided inside the lower side surface 12c and the upper side surface 12d. On the other hand, the outer edges 13b1, 13b2 of the first engagement piece 13b on the lower side surface 12c side are provided approximately on the same plane as the left side surface 12a or the right side surface 12b, respectively.

Each of the first engagement pieces 13a, 13b is formed in a rectangular plate shape with both corners on the tip side rounded. A protrusion 132 that protrudes toward the surface 11a of the main body 11 is formed on the upper side of the first engagement pieces 13a, 13b. The protrusion 132 extends linearly in the width direction of the first engagement pieces 13a, 13b.

Second engagement pieces 15a, 15b (15) are formed on the right side surface 12b and the upper side surface 12d (second side surface) via the base 151 (see Figures 2, 4(a) and 4(b)) on the back surface 11b side of the right side surface 12b and the upper side surface 12d, respectively, extending laterally. The second engagement piece 15a on the right side surface 12b side is provided in two places. The second engagement piece 15b on the upper side surface 12d side is provided in one place on the center side of the upper side surface 12d. The second engagement piece 15a on the right side surface 12b is provided narrower than the second engagement piece 15b on the upper side surface 12d. Each of the second engagement pieces 15a, 15b is also formed in a rectangular plate shape with both corners on the tip side rounded.

In this way, the number of first engagement pieces 13a formed on the left side surface 12a in the first direction X of the main body 11 is different from the number of first engagement pieces 13b formed on the lower side surface 12c in the second direction Y perpendicular to the first direction X. Also, the number of second engagement pieces 15a formed on the right side surface 12b in the first direction X is different from the number of second engagement pieces 15b formed on the upper side surface 12d in the second direction Y.

Between the first engagement pieces 13a, 13b, insertion portions 14a, 14b (14) (first insertion portions) are formed. Also, on the right side surface 12b and the upper side surface 12d, insertion portions 16a, 16b (16) (second insertion portions) are formed on both sides of the second engagement pieces 15a, 15b, respectively. The insertion portions 14a, 14b are provided adjacent to the first engagement pieces 13a, 13b, and the insertion portions 16a, 16b are provided adjacent to the second engagement pieces 15a, 15b. Also, the insertion portions 14a, 14b, 16a, 16b are rectangular cutout spaces that have a cutout depth equal to the thickness of the first engagement pieces 13a, 13b or the second engagement pieces 15a, 15b and open to the back surface 11b side (see also Figures 4(a) and 4(b)).

Of the multiple insertion sections 16a, 16b spaced apart on the right side surface 12b and upper side surface 12d, the two end insertion sections 16a, 16b are provided at the ends of the respective side surfaces 12b, 12d (i.e., the corners of the main body 11).

As shown in FIG. 2, a groove 161 is provided on the back surface 11b opposite the front surface 11a within the insertion portions 16a, 16b of the right side surface 12b and the upper side surface 12d. The groove 161 is provided adjacent to the inner wall of the right side surface 12b or the upper side surface 12d, and opens in a slit shape on the back surface 11b side of the main body 11. The protrusion 132 of the first engagement piece 13 of another retainer 1 can be engaged with this groove 161 to connect multiple retainers 1 together.

As shown in FIG. 1, a flange 112 is formed around the outer periphery of the side surface 12. The flange 112 is formed around the outer periphery of each of the side surfaces 12a to 12d. The flange 112 is provided at the end of the back surface 11b side of the side surface 12 at positions corresponding to the insertion portions 14 and 16, and is provided on the base ends of the first engagement piece 13 and the second engagement piece 15 at positions corresponding to the first engagement piece 13 and the second engagement piece 15, respectively.

Here, the structure of the connected holders 1 will be described. Holder 1A in FIG. 4(a) shows a combined cross-sectional view of holder 1 in FIG. 3 taken along line IVa-IVa, and includes the connected portion when multiple holders 1B, 1C are connected in the left-right direction. Note that the structure of insert portion 14a (not shown) on the left side surface 12a of central holder 1A is similar to that of insert portion 14a on the left side surface 12a of right-side holder 1B. Also, the structure of insert portion 16a (not shown) on the right side surface 12b of central holder 1A is similar to that of insert portion 16a on the right side surface 12b of left-side holder 1C.

The retainers 1 are connected in the left-right direction by aligning the left side surface 12a of one retainer 1 with the right side surface 12b of the other retainer 1, and inserting and engaging the first engagement piece 13a and the second engagement piece 15a into the corresponding insertion portions 16a, 14a of the adjacent retainer 1.

When the first engagement piece 13a is inserted into the insertion portion 16a, the flange-shaped portions 112 come into contact with each other, positioning the holders 1 in the direction of approach, and the protrusion 132 can engage with the groove portion 161 from the back surface 11b side. This restricts the movement of the connected holders 1 in the left-right direction (first direction X). In addition, the first engagement piece 13a can come into contact with the wall portion of the right side surface 12b that forms the insertion portion 16a, and the second engagement piece 15a can come into contact with the wall portion of the left side surface 12a that forms the insertion portion 14a. Therefore, the first engagement piece 13a and the second engagement piece 15a restrict the movement of the adjacent holders 1 in the directions of the front surface 11a and the back surface 11b. Therefore, the holders 1A, 1B, and 1C connected in the left-right direction (first direction X) are connected so as not to be separated from each other.

The retainer 1A in FIG. 4(b) shows a combined cross-sectional view of the retainer 1 in FIG. 3 taken along line IVb-IVb, and includes the connecting portion when multiple retainers 1D, 1E are connected in the vertical direction. Note that in FIG. 4(b) as well, the configuration of the insert portion 14b (not shown) on the lower surface 12c of the central retainer 1A is similar to the insert portion 14b on the lower surface 12c of the upper retainer 1D. Also, the configuration of the insert portion 16b (not shown) on the upper surface 12d of the central retainer 1A is similar to the configuration of the insert portion 16b on the upper surface 12d of the lower retainer 1E.

The retainers 1 are connected in the vertical direction by aligning the lower surface 12c of one retainer 1 with the upper surface 12d of the other retainer 1, and inserting and engaging the first engagement piece 13b and the second engagement piece 15b into the corresponding insertion portions 16b, 14b of the adjacent retainer 1.

When the first engagement piece 13b is inserted into the insertion portion 16b, the flange-shaped portions 112 come into contact with each other, positioning the holders 1 in the direction of approach, and the protrusion 132 can engage with the groove portion 161 from the back surface 11b side. This restricts the movement of the connected holders 1 in the vertical direction (second direction Y). In addition, the first engagement piece 13b can come into contact with the wall portion of the upper surface 12d that forms the insertion portion 16b, and the second engagement piece 15b can come into contact with the wall portion of the lower surface 12c that forms the insertion portion 14b. Therefore, the first engagement piece 13b and the second engagement piece 15b restrict the movement of the adjacent holders 1 in the directions of the front surface 11a and the back surface 11b. Therefore, the holders 1A, 1D, and 1E that are connected in the vertical direction (second direction Y) are connected so as not to be separated from each other.

In this way, by alternately inserting and engaging the first engagement piece 13 and the second engagement piece 15 into the insertion portions 14, 16 of adjacent retainers 1, the retainers 1 can be connected to each other, thereby increasing the area of the surface 11a and the number of openings 111.

Returning to FIG. 2, the holder 1 has an opening 17 on the back surface 11b side. The opening 17 is formed as a circular recess into which the engagement parts 24, 35, and 46 of the joint members 2, 3A, 3B, and 4 described below can be fitted. The openings 17 are formed in two places, on the left and right sides, on the lower end side.

Figure 5 shows a number of joint members 2, 3A, 3B, 4 of different shapes. The joint member 2 has a cylindrical shaft portion 21 extending in one direction, a hexagonal flat-plate-shaped flange portion 22 formed around the shaft portion 21, and bulges 23 protruding around the outer periphery at both ends of the shaft portion 21. The flange portions 22 are provided at two locations spaced apart from each other on the shaft portion 21. The axial lengths of the middle portion 21a and the end portion 21b of the shaft portion 21 are formed to be approximately the same. The bulges 23 protrude radially outward around the shaft portion 21. The end portion 21b, the flange portion 22, and the bulges 23 form engagement portions 24 (first engagement portion and second engagement portion) on both ends of the joint member 2.

The joint members 3A and 3B have rectangular flat intermediate portions 31A and 31B extending in one direction, flange portions 32 formed on both ends of the intermediate portions 31A and 31B, cylindrical shaft portions 33 extending in the longitudinal direction of the intermediate portions 31A and 31B via the flange portions 32, and bulging portions 34 formed on both ends of the shaft portion 33. The intermediate portion 31B is formed to be longer than the intermediate portion 31A, so that the joint member 3B is formed to be longer overall than the joint member 3A.

The shape and size of the flange portion 32, shaft portion 33 and bulge portion 34 are formed in the same manner as the flange portion 22, end portion 21b and bulge portion 23 of the joint member 2, respectively. Therefore, the flange portion 32, shaft portion 33 and bulge portion 34 form engagement portions 35 (first engagement portion and second engagement portion) on both ends of the joint members 3A and 3B, similar to the engagement portion 24. The engagement portions 35 are formed on both ends, sandwiching an opening portion 36 located approximately in the center of the intermediate portions 31A and 31B.

The opening 36 is formed as a circular through hole that can engage with the engaging portions 24, 35, 46 of the other joint members 2, 3A, 3B, 4. On both sides of the plate surface of the intermediate portions 31A, 31B, short cylindrical portions 361 that form the open ends of the opening 36 are formed. On the inner peripheral surface of the opening 36, inner peripheral protrusions 362 that protrude radially inward are formed. The inner peripheral protrusions 362 are formed at four locations in the circumferential direction. The bulging portions 23, 34, 45 are formed so as to be able to engage with the inner peripheral protrusions 362.

The joint member 4 has a bifurcated engagement recess 43 (second engagement portion) formed by a rectangular bottom plate 41 and side plates 42 extending substantially perpendicularly from both ends of the long side of the bottom plate 41. The width between the side plates 42 in the engagement recess 43 is formed to be substantially the same as or slightly narrower than the outer shape of the fusible bead toy 51 described later in FIG. 7. The joint member 4 also has a cylindrical shaft portion 44 erected from the bottom of the bottom plate 41 on the side opposite the engagement recess 43, and a bulge portion 45 formed at the end of the shaft portion 44. The shape and size of the shaft portion 44 and the bulge portion 45 are formed in the same way as the end portion 21b and the bulge portion 23 of the joint member 2, respectively. The bottom plate 41, the shaft portion 44, and the bulge portion 45 also form an engagement portion 46 (first engagement portion) similar to the engagement portion 24.

The engaging portions 24, 35, 46 of the joint members 2, 3A, 3B, 4 have shaft portions 21 (ends 21b), 33, 44 formed with a diameter smaller than the inner diameter of the opening 36, so that they can be inserted into the opening 36 of another joint member 3A, 3B to connect two or more joint members 2, 3A, 3B, 4 (see also FIG. 6). At this time, the bulges 23, 34, 45 can overcome the inner peripheral protrusion 362 in the opening 36 in the insertion direction and engage with the inner peripheral protrusion 362. Therefore, the engaging portions 24, 35, 46 can be prevented from coming off the opening 36.

The engaging portions 24, 35, 46 formed on the joint members 2, 3A, 3B, 4 are formed to be able to engage with the opening 111 of the retainer 1 (see also the joint member 2 shown by the two-dot chain line in FIG. 4(a)). The inner diameter of the opening 111 is larger than the shaft portions 21 (ends 21b), 33, 44 of the engaging portions 24, 35, 46, and smaller than the bulges 23, 34, 45. When the engaging portions 24, 35, 46 are inserted into the opening 111, the bulges 23, 34, 45 are pressed against the inner circumferential surface of the opening 111, and the joint members 2, 3A, 3B, 4 can be engaged with a force that does not easily come off.

Figure 7 is a diagram showing an example of the use of the holder 1. The holder 1 can hold the assemblies 5A and 5B, which are formed by welding together a plurality of weldable bead toys 51 made of water-soluble resin, via any of the joint members 2, 3A, 3B, and 4. The weldable bead toys 51 are formed in a spherical shape made of a synthetic resin containing polyvinyl alcohol. The assemblies 5A and 5B are formed by placing a plurality of weldable bead toys 51 on a tray (not shown) and wetting them with a spray bottle or the like to weld adjacent weldable bead toys 51 to each other. In this embodiment, the assembly 5A imitates a human figure, and the assembly 5B imitates a sword. The assembly 5A and the assembly 5B are provided with openings 5A1 and 5B1 (second engaged parts) formed by opening (missing) one weldable bead toy 51, respectively. The engagement parts 24, 35 of the joint members 2, 3A, 3B are configured to be able to engage with the openings 5A1, 5B1 formed in the assemblies 5A, 5B. The opening edges of the openings 5A1, 5B1 through which the engagement parts 24, 35 are inserted come into contact with the flange parts 22, 32 and are stably supported.

In the example of FIG. 7, assembly 5A is held by holder 1 via joint member 3A. Furthermore, assembly 5B is held by holder 1 via joint member 2. Since joint member 3A and joint member 2 have different lengths in the longitudinal direction, assembly 5A and assembly 5B can be positioned at different heights. Therefore, holder 1 can also stack multiple assemblies 5A and 5B, allowing it to hold many assemblies.

The assemblies 5A and 5B may be held by clamping the weldable bead toy 51 arranged at the end of the assemblies 5A and 5B with the engagement recess 43 of the joint member 4 shown in FIG. 5. The engagement portion 46 of the joint member 4 may be attached to the other joint members 3A and 3B.

By attaching the joint members 2, 3A, and 3B to the two openings 17 (see FIG. 2) mentioned above, the holder 1 can be placed upright with the surface 11a tilted. Because the flanges 22 and 32 of the joint members 2, 3A, and 3B are formed in polygonal plate shapes, the C-chamfered outer edges of the flanges 22 and 32 can be abutted against the placement surface of the holder 1. Therefore, the holder 1 can be placed stably upright.

According to the above-described embodiment of the present invention, a holder having the following features can be provided.

The holder according to the first aspect is a holder for an assembly of multiple weldable bead toys made of water-soluble resin welded together, and includes a main body having a first engaged portion, a first engaging portion that can engage with the first engaged portion, and a joint member having a second engaging portion that can engage with a second engaged portion formed on the assembly.

In the fourth aspect of the retainer, the through hole has an inner peripheral protrusion on the inner peripheral surface, and a flange-shaped portion that can engage with the inner peripheral protrusion is formed around the outer periphery of the first engagement portion and the second engagement portion that can engage with the through hole.

This configuration allows multiple joint members to be stably connected to each other.

In the fifth aspect of the holder, another part of the joint members includes the second engagement portion formed in a bifurcated shape capable of clamping the weldable bead toy of the assembly.

This configuration allows for greater freedom in the shape of the assembly to be connected to the joint member and the position at which it is supported.

In the sixth aspect of the retainer, the first engaged portion is formed on a first surface of the plate-shaped main body portion, the main body portion having a first side and a second side, the first side is formed with a first engagement piece extending from the first side and a first insertion portion which is a space provided adjacent to the first engagement piece, and the second side is formed with a second engagement piece extending from the second side and having a shape which can be inserted into the first insertion portion, and a second insertion portion which is a space provided adjacent to the second engagement piece and into which the first engagement piece can be inserted.

With this configuration, the area of the holder can be expanded as desired, and the size and number of assemblies to be held can also be set as desired.

In the seventh aspect of the retainer, the first engagement piece is formed with a protrusion that protrudes toward the first surface, and a groove that can engage with the protrusion is formed on a second surface of the second insertion portion opposite the first surface.

This configuration allows the connection between the holders 1 to be stably maintained.
