Problems to be Solved by the Invention

In the conventional engagement depressed portion 11, the pair of side walls 21, 21, or the bottom wall 23 may be cracked if the expanded portion 17 of the engagement raised portion 9 is repeatedly pushed into and pulled out from between the projecting portions 19, 19 of the engagement depressed portion 11, namely, if engagement/disengagement is repeated.
Accordingly, it is an object of the present invention to provide a toy assembly unit in which a bottom wall or base portions of a pair of side walls of an engagement depressed portion can be prevented from being cracked even if engagement/disengagement is repeated.
It is another object of the present invention to provide a toy assembly unit in which an expanded portion of an engagement raised portion can easily be inserted into between projecting portions of an engagement depressed portion respectively located on the either side at a longitudinal end thereof.
It is a further object of the present invention to provide a toy assembly unit in which end portions of a pair of side walls of an engagement depressed portion can easily be bent outwardly, and mechanical strength of a bottom wall can be improved.
It is still another object of the present invention to provide a toy assembly unit in which a pair of side walls of an engagement depressed portion can easily be bent.
It is yet another object of the present invention to provide a transformable toy in which a bottom wall or base portions of a pair of side walls of an engagement depressed portion in a connecting mechanism can be prevented from being cracked.

Means of Solving the Problem

A toy assembly unit according to an embodiment of the present invention comprises a first component unit including an engaging portion and a second component unit including an engaged portion into which the engaging portion is detachably engaged. The engaging portion is constituted by one of an engagement raised portion and an engagement depressed portion. The engaged portion is constituted by the other of the engagement raised portion and the engagement depressed portion. The engagement raised portion includes a base, a plate-like portion integrally formed with the base and extending away therefrom, and an expanded portion integrally formed with the plate-like portion in such a manner that the expanded portion is disposed along an end portion of the plate-like portion. The engagement depressed portion is formed, being surrounded by a pair of side walls and a bottom wall. The pair of side walls have flexibility and are disposed at a given interval to sandwich the plate-like portion and the expanded portion therebetween. The bottom wall connects base portions of the pair of side walls, each of the side walls having a projecting portion formed integrally therewith at an end portion thereof for preventing the expanded portion from coming off. In particular, the bottom wall has one or more through-holes which extend along a gap formed between the pair of projecting portions respectively formed with the pair of side walls, and pass through the bottom wall toward the gap.
When one or more through holes are provided in the bottom wall constituting the engagement depressed portion, portions of the bottom wall in the periphery of the through holes may easily be curved convexly toward the above-mentioned gap so as to narrow the interval or gap in a width direction, thereby bending end portions of the pair of side walls outwardly. As a result, the pair of side walls can be bent more easily than ever, thereby preventing the bottom wall and the pair of side walls of the engagement depressed portion from being cracked when pushing or puling out the expanded portion of the engagement raised portion into or from between the projecting portions of the engagement depressed portion respectively located on either side of the interval or gap. Therefore, according to the present invention, the life of the engagement depressed portion can be extended and reliability can be increased.
Preferably, the length of the projecting portion in a direction along the gap is smaller than that of the pair of side walls in the direction along the gap, and the projecting portions do not exist at both ends, in the direction along the gap, of the end portions of the side walls. With such configuration, once one end of the expanded portion of the engagement raised portion has got into a space which exists on both sides of the end portions of the side walls in the direction along the gap, where the projecting portions do not exist, the engagement raised portion can smoothly be inserted into between the pair of projecting portions. In this manner, the engagement raised portion can be engaged with or inserted into the engagement depressed portion with no difficulty even if both portions are not exactly opposed to each other.
Preferably, a plurality of through holes are formed side by side along the gap. With such arrangement, namely, due to the existence of the through holes in the bottom wall, the end portions of the pair of side walls of the engagement depressed portion can readily be bent outwardly.
Preferably, the pair of side walls and the bottom wall are integrally formed with a synthetic resin material. In the above-mentioned configuration, flexibility of the synthetic resin material can be utilized most, thereby readily bending outwardly the pair of side walls partially surrounding the engagement depressed portion.
The present invention is, of course, applicable to a transformable toy comprising a plurality of component units and one or more connecting mechanisms respectively including an engaging portion and an engaged portion to be engaged with the engaging portion for connecting the component units to each other. The transformable toy is transformed from one figure into another figure by changing a combination of the plurality of component units connected to each other, or replacing some of the component units with a prepared separate component unit using the connecting mechanism, or adding a prepared separate component unit to the plurality of component units using the connecting mechanism.
In a transformable toy according to an embodiment of the present invention, the engaging portion is constituted by one of an engagement raised portion and an engagement depressed portion; and the engaged portion is constituted by the other of the engagement raised portion and the engagement depressed portion. The engagement raised portion includes a base, a plate-like portion integrally formed with the base and extending away therefrom, and an expanded portion integrally formed with the plate-like portion in such a manner that the expanded portion is disposed along an end portion of the plate-like portion. The engagement depressed portion is formed, being surrounded by a pair of side walls which have flexibility and are disposed at a given interval to sandwich the plate-like portion and the expanded portion therebetween; and a bottom wall connecting base portions of the pair of side walls, each of the side walls having a projecting portion formed integrally therewith at an end portion thereof for preventing the expanded portion from coming off. The bottom wall has one or more through-holes which extend along a gap formed between the pair of projecting portions respectively formed with the pair of side walls, and pass through the bottom wall toward the gap.
Preferably, in the transformable toy according to the present invention, the length of the projecting portion in a direction along the gap is smaller than that of the pair of side walls in the direction along the gap, and the projecting portions do not exist at both ends, in the direction along the gap, of the end portions of the pair of side walls. Preferably, a plurality of the through-holes are formed side by side along the gap. Preferably, the pair of side walls and the bottom wall are integrally formed with a synthetic resin material.

The best mode for carrying out the invention will be described in detail hereinafter with reference to the drawings.
FIGS. 1A and 1B to FIGS. 4A and 4B show one embodiment in the best mode for carrying out the present invention. FIG. 1A is a perspective view showing a configuration of an engaging portion and an engaged portion used for a toy assembly unit of the present embodiment, and FIG. 1B is a reversed perspective view of FIG. 1A. FIGS. 2A, 2B, 2C, 2D, 2E and 2F are a front view, a plan view, a bottom view, a left side view, a right side view, and a cross-sectional view taken along line A-A of FIG. 2B of the engaged portion used in the present embodiment.

FIGS. 4A and 4B are explanatory views showing how the engaging portion is inserted into one end, in the longitudinal direction, of the engaged portion in the present embodiment. In the present embodiment, components and portions similar to those of the conventional art as shown in FIG. 8 have their reference numerals calculated by adding a number of 100 to the corresponding reference numerals shown in FIG. 8.
In the present embodiment, an engagement raised portion 109 constitutes the engaging portion provided in a first component unit, not shown, and an engagement depressed portion 111 constitutes the engaged portion provided in a second component unit, not shown.
The engagement raised portion 109 is integrally formed with a synthetic resin material. As shown in FIGS. 1A and 1B, the engagement raised portion 109 includes a plate-like base 113, a plate-like portion 115 integrally formed with the base 113 and extending orthogonally away therefrom, and a cylindrical expanded portion 117 integrally formed with the plate-like portion 115 in such a manner that the expanded portion 117 is disposed along an end portion of the plate-like portion 115.
The engagement depressed portion 111 is formed, being surrounded by a pair of side walls 121,121 which have flexibility and a bottom wall 123, as shown in FIGS. 1A, 1B and FIGS. 2A, 2B, 2C, 2D, 2E, and 2F. The pair of side walls 121,121 are opposed to each other at a given interval or gap 125. The pair of side walls 121,121 sandwich the plate-like portion 115 and the expanded portion 117 of the engagement raised portion 109 therebetween. Each of the side walls 121, 121 has a projecting portion 119 formed integrally therewith at an end portion thereof for preventing the expanded portion 117 from coming off. The bottom wall 123 connects base portions of the pair of side walls 121,121. The above-mentioned interval or gap 125 is defined so that the expanded portion 117 may be received between the pair of side walls 121,121.
The bottom wall 123 constituting the engagement depressed portion 111 has a through hole 129 of a rectangular shape. The through hole 129 extends along a gap 127 formed between the pair of projecting portions 119 respectively formed with the pair of side walls 121,121, and passes through the bottom wall 123 toward the gap 127.
The length of the projecting portion 119 in a direction along the gap 127 is smaller than that of the pair of side walls 121, 121 in the direction along the gap 125. As a result, the projecting portions 119 do not exist at both ends, in the direction along the gap 125, of the end portions of the side walls 121, 121. Thus, spaces (slits) 131, 131 are formed.
The pair of side walls 121,121 and the bottom wall 123, as thus constituted, are integrally formed with a synthetic resin material. The engagement raised portion 109 is also integrally formed with the synthetic resin material. A typical example of the synthetic resin materials that form the engagement raised portion 109 and engagement depressed portion 111 is polyacetal (POM).
As shown in FIGS. 3A and 3B, the expanded portion 117 of the engagement raised portion 109 is pushed into between the projecting portions 119,119 of the engagement depressed portion 111, respectively located on either side of the interval or gap. Then, as shown in FIG. 3C, the expanded portion 117 is inserted between the projecting portions 119,119 when the end portions of the pair of side walls 121, 121 are bent outwardly by the expanded portion 117. Accordingly, as shown in FIG. 3D, the plate-like portion 115 of the engagement raised portion 109 is located between the projecting portions 119,119 respectively located on the either side. The expanded portion 117 is received in the interval or gap 125 between the pair of side walls 121,121, and the expanded portion 117 is prevented from coming off due to the existence of the projecting portions 119,119. In this manner, the engagement of engagement raised portion 109 and the engagement depressed portion 111 is completed.
In the toy assembly unit thus configured, since the bottom wall 123 partially surrounding the engagement depressed portion 111 has one through-hole 129 which extends along the gap 127 formed between the pair of projecting portions 119, 119, and passes through the bottom wall 123 toward the gap 127, the bottom wall 123 curves convexly toward the gap 127 when the end portions of the pair of side walls 121,121 are bent outwardly. As a result, the pair of side walls 121,121 are easily bent outwardly, thus preventing the bottom wall 123 and the base portions of the pair of side walls 121,121 of the engagement depressed portion 111 from being cracked when the expanded portion 117 of the engagement raised portion 109 is inserted between the projecting portions 119,119 of the engagement depressed portion 111 respectively located on the either side. Consequently, the life of the engagement depressed portion 111 is extended and reliability is increased.
Once one end of the expanded portion 117 of the engagement raised portion 109 has got into one of spaces 131, 131 respectively formed on either side of the end portions of the pair of side walls 121, 121 in the direction along the interval or gap 125, where the projecting portions do not exist, the engagement raised portion 109 is smoothly inserted between the pair of projecting portions 119, 119. In this manner, the engagement raised portion 109 can readily be engaged with or inserted into the engagement depressed portion 111 with no difficulty even if both portions are not exactly opposed to each other.
Preferably, a plurality of through holes 129 may be formed side by side in the bottom wall 123 at a given interval along the gap 127. In this manner, flexibility of the bottom wall 123 is adjustable by defining the number of the plurality of through hole 129. Since portions between the adjoining through holes 129 formed in the bottom wall 123 are connected to each other in a width direction thereof, mechanical strength of the bottom wall 123 is also adjustable by appropriately determining the number of the through holes.
FIGS. 5 to 7 illustrate how the connecting mechanism, which is constituted by the above-mentioned engagement raised portion 109 and engagement depressed portion 111, is applied to a transformable toy in order to connect a core robot toy and a large robot toy. FIG. 5 is a front view of the core robot toy, and FIGS. 6A and 6B are a front view and a cross-sectional side view taken along line B-B of the large robot toy that does not incorporate the core robot toy therein. FIG. 7 is a partial vertical cross-sectional view showing the principal configuration of the large robot toy incorporating the core robot toy therein.
In the present embodiment, the transformable toy is transformed into the large robot toy shown in FIGS. 6A and 6B by mounting a plurality of divided components, which have been obtained by dividing another robot toy, onto the core robot toy shown in FIG. 5, which works as the core of the large robot toy.

The divided component 145 including the operation portion 149 incorporates an operation mechanism 151 that allows direct operation of the switch when the divided component 145 is mounted on the core robot toy 133. The operation mechanism 151 is divided into three operation mechanism portions 151 a, 151 b, and 151 c which are included in the assembly components 145 a and 145 b. The operation mechanism portion 151 a is included in the assembly component 145 a and is configured to move up and down longitudinally so as to press a keytop of the switch. The operation mechanism portion 151 b is included in the assembly component 145 a and is configured to move laterally in a direction orthogonal to an extending direction of the operation mechanism portion 151 a so that the operation mechanism 151 b is pushed to slide, which in turn pushes down the operation mechanism portion 151 a. The operation mechanism portion 151 c is included in the assembly component 145 b and is aligned with a base end of the operation mechanism portion 151 b so that pressing the operation mechanism portion 151 c may move backward the operation mechanism 151 b.
The assembly component 145 b, which is disposed in the front side of the divided component 145 that constitutes the chest section, is configured in the shape of a lion head.
In the present embodiment, when the inside of a widely opened mouth of the lion head is lighted by emission of the light-emitting display portion 138 disposed in the core robot toy 133, the large robot toy 143 is in a light-emitting display state.
The engagement raised portion 109 and the engagement depressed portion 111 may be disposed interchangeably.

INDUSTRIAL APPLICABILITY
