TECHNICAL FIELD

The present invention relates to a transformable toy, of which the figure can be changed from a state in which a toy doll is riding on a movable toy to a toy robot having a configuration different from that of the toy doll, and also relates to a toy foot structure used in the toy robot, and further relates to a transformable toy provided with the toy foot structure.

BACKGROUND ART

Japanese Utility Model Laid-Open Publication No. H05-195 (Patent Document 1) shows an example of a transformable toy capable of changing its figure from a state where a toy doll is riding on a movable toy to a toy robot having a configuration different from that of the toy doll by transforming at least a part of the movable toy and mounting it on the toy doll. In this disclosure, the toy robot is constituted merely by disassembling the movable toy to obtain an assembly constituent section and mounting the obtained constituent section onto the toy doll.

Japanese Utility Model Laid-Open Publication No. S60-102092 (Patent Document 2), Japanese Utility Model Laid-Open Publication No. S61-77094 (Patent Document 3), and Japanese Utility Model Laid-Open Publication No. S64-20891 (Patent Document 4) show examples of a transformable toy constituting a toy robot by transforming an autobicycle.

FIG. 2 of Japanese Utility Model Laid-Open Publication No. S61-45993 shows an example of a toy foot structure in which a foot having a tiptoe and a heel is mounted to a shin section in such a manner that the foot section can incline and move in a back and forth direction with respect to the shin section. This conventional toy foot structure is applied to a doll-type toy robot which opens its pair of leg sections back and forth, enabling the tiptoe and the heel of the foot to be always in full contact with a setting surface when the pair of leg sections are opened back and forth.

FIGS. 1 through 3 of the Utility Model Registration Publication No. 3079299 show an example of a toy foot structure in which an ankle includes a spherical portion, a shin section includes a spherical seat for receiving the spherical portion so that a foot can freely rotate with respect to the shin section.

DISCLOSURE OF THE INVENTION

Problem to be Solved by the Invention

In the transformable toy shown in Patent Documents 1, since the transformation is carried out in a comparatively simple way, namely, merely by equipping the toy doll with the assembly constituent section obtained merely by disassembling the movable toy, there is a limitation in enjoying the transformation process.

There is also another problem that an unpredictable transformation can be hardly expected. In the case of the structure described in Japanese Utility Model Laid-Open Publication No. S61-45993, when the pair of leg sections are opened right and left, only the inner edges of the tiptoes and the heels are in contact with the setting surface. Therefore, when the conventional structure is applied to the doll-type toy robot which is constructed to open its pair of leg sections right and left, there occurs a problem that it is difficult to keep a well-stabilized standing condition for the toy robot.

As compared with that, if the structure described in the Utility Model Registration Publication No. 3079299 is employed, even when the pair of leg sections are opened right and left, the soles of the feet can be always in full contact with the setting surface. However, in the joint structure using the combination of the spherical portion and the spherical seat, a slip easily occurs between the spherical portion and the spherical seat just by a small force applied from the outside. Thus, it is difficult to keep a well-stabilized standing condition for the toy robot with the pair of legs opened. Moreover, with the joint structure using the combining of the spherical portion and the spherical seat, it is impossible to constrain the feet and the shin sections in a particular positional relationship in order to always attain the particular positional relationship. Therefore, if the structure is employed for connecting a foot to a shin section of a transformable toy, when portions used as a foot or a shin section in the transformable toy are used for a certain component in the after-transformed figure, there occurs a problem that a degree of freedom in designing the transformable toy will be limited since it is hard to fix the connecting state between the portions used as the foot and the shin section.

An object of the present invention is accordingly to provide a transformable toy with which an unprecedented transforming process can be enjoyed.

Another object of the present invention is to provide a transformable toy in which a movable toy carries out an unpredictable transformation.

A further object of the present invention is to provide a transformable toy in which a transformation process can be fully enjoyed in making an exterior to be mounted on a toy doll by transforming an assembly constituent section constituting an autobicycle.

Still another object of the present invention is to provide a transformable toy in which a fuel tank of the autobicycle does not get in the way of transformation.

Yet another object of the present invention is to provide a transformable toy in which an exterior composed of an assembly constituent section of a movable toy is hardly separated from a toy doll.

Even another object of the present invention is to provide a toy foot structure which enables a toy to keep standing in a more stabilized condition than ever even when the toy doll opens its legs right and left.

A still further object of the present invention is to provide a transformable toy having a toy foot structure capable of achieving the above-mentioned object without reducing a degree of freedom in designing the transformable toy.

MEANS FOR SOLVING THE PROBLEM

The present invention is directed to a transformable toy, the figure of which can be changed from a state where a toy doll is riding on a movable toy (such as a two-wheeled vehicle) to a toy robot having a configuration different from that of the toy doll by transforming at least a part of the movable toy and mounting it on the toy doll. The movable toy typically includes any of an autobicycle, a bicycle, an automobile, a motorboat, and an airplane. The toy doll may not be limited to a doll of human being's figure, and may be a figure of robot by itself. A movable toy includes an assembly which is composed of a plurality of components, and is mounted onto an upper body of the toy doll to constitute an exterior for an upper body of the toy robot. The assembly includes a first assembly constituent section, a second assembly constituent section, and a third assembly constituent section, each of which is composed of one or more components. The first assembly constituent section is mainly disposed in a front side of the toy doll. The second assembly constituent section is connected to the first assembly constituent section and disposed in a back side of the toy doll. The third assembly constituent section connects the first and second assembly constituent sections. The first, second and third assembly constituent sections are assembled together in an annular shape to constitute the exterior of the toy doll. The exterior surrounds at least shoulders, a crotch, the front side and the back side of the toy doll. There is no annular exterior configuration in the past, and there is also no such transformation process as constituting the above-mentioned exterior in the past. Therefore, according to the transformable toy of the present invention, unprecedented process of transformation can be enjoyed. In addition, unexpected transformation of the assembly which constitutes a part of the movable toy can increase the user's interest in the transformable toy.

In particular, if the third assembly constituent section is disposed on the shoulders of the toy doll so that a head section of the toy doll can be exposed, the head section of the toy doll can be used as a head of the toy robot as it is. In addition, just an easy work of surrounding a main part (doll body part) of the toy doll with the assembly can firmly mount the exterior having a sense of robustness onto the upper body of the toy doll. Still more, since the head section exposed from the third assembly constituent section works as a positioning means and a movement prevention means at the time of attaching the assembly to the toy doll, such an advantage can be obtained that the assembly can be easily mounted onto the toy doll. Those components constituting the movable toy may include a pair of shin section constituents composed of one or more components. The pair of shin section constituents are attached to a pair of leg sections of the toy doll, and constitute shin sections of the pair of leg sections for the toy robot. If the pair of the shin section constituents are attached to the toy doll, even when the upper body of the toy doll is equipped with a comparatively big exterior, it becomes possible to make a good balance between a weight of the lower body of the toy robot and a weight of the upper body of the toy robot. As a result, stability of the toy robot can be increased.

When the movable toy is an autobicycle, the first assembly constituent section may include a front cover, a front fork, and a front frame of the autobicycle. The second assembly constituent section may include a fuel tank, a sitting portion, a rear frame, and a rear cover. The third assembly constituent section may include a handle. In this case, at least the front frame and the rear frame are rotatably connected, and the fuel tank is constituted by assembling two tank half portions that can be separated apart right and left. The two tank half portions are attached to the rear frame in such a manner that the front frame can pass through between the two tank half portions which are separated apart left and right when assembling the first, second and third assembly constituent sections in the annular shape. If the first through third assembly constituent sections are assembled together in this way, when the annular exterior is formed, the tank half portions of the fuel tank are opened right and left. Since the front frame can be rotated in a direction toward the rear frame through a clearance made between the two tank half portions, the presence of the fuel tank does not get in the way in constituting the annular exterior.

Preferably, an engaged portion, which is a recessed or raised portion, is arranged in the back side of the toy doll. In this case, a cover part of the rear cover, which is located by the side of the sitting portion, is supported by a rear cover body of the rear cover in such a manner that the cover part can be turned over. An engaging portion engaging with the engaged portion of the toy doll is arranged in a turned-over side of the cover part. In this way, the exterior can be mounted onto the toy doll without causing loosening between the exterior and the toy doll by engaging the engaged portion arranged in the back side of the toy doll and the engaging portion arranged in the rear cover side. In particular, since the cover part of the rear cover can be turned over, when the toy is not transformed into the toy robot, the presence of the engaging portion does not get in the way.

When a handle is included in the third assembly constituent section, a construction of the handle and a construction of the rear cover are defined so that end portions of a pair of arm parts of the handle can engage with the rear cover to constitute the exterior in the annular shape, and the handle can be located over the shoulders of the toy doll. In this way, the head section of the toy doll can be exposed from between the pair of arm parts of the handle. What is more, the head section of the toy doll can be used as it is as a head of the toy robot.

Preferably, the front frame and the front fork are connected to rotate in a predetermined angular range and the rear frame and the rear cover are connected to rotate in a predetermined rotation range. In this manner, the number of rotatable connecting components included in the annular exterior will increase. As a result, transformation of the annular exterior becomes easy and what is more, the annular exterior can be transformed substantially in accordance with the shape of the upper body of the toy doll.

As the pair of shin section constituents, a pair of muffler constituent sections of the autobicycle may be used. Each of two wheels of the autobicycle may be constructed to be divided into two parts in a direction orthogonal to the wheel's axle to form wheel half portions. In this case, the wheel half portions of the two wheels are mounted onto the exterior and/or both of the shin sections of the toy robot respectively. In this manner, the tires can be mounted onto the toy robot as if they were a part of armor thereof. As a result, an image of the autobicycle before transformation can be considerably faded out and deformation degree of the transformable toy can be further increased.

The present invention is also directed to a toy foot structure in which a foot having a tiptoe section and a heel section is attached to under a shin section. In the specification of the present invention, the tiptoe means a part of the foot except the heel, the main part or the whole portion situated ahead of the heel within the foot section. In the present invention, a heel mounting mechanism comprises a foot section having a tiptoe section and a heel section, and a heel mounting mechanism that attaches the heel section to the shin section. The heel mounting mechanism is constructed in such a manner that the heel section can move with respect to the shin section so that a whole bottom face of the heel can be in full contact with a setting surface whenever the shin section stands erect or the shin section is inclined in a lateral direction as seen from the tiptoe side. According to the present invention, the whole bottom face of the heel section is always in full contact with the setting surface whether or not the shin section is inclined, and at least a part of the end portions of the tiptoe section comes into contact with the setting surface when the shin section is inclined. As a result, according to the present invention, the two sections, the heel and the tiptoe, can always be in contact with the setting surface in principle. The full contact between the bottom face of the heel and the setting surface contributes to maintaining a stable, stationary position when the toy stands with its leg sections opened. The contact between the tiptoe and the setting surface works to prevent the inclination of the shin sections from changing with a slight application of external force. As a result, according to the present invention, even when the toy is installed on the setting surface with the leg sections thereof opened, the toy can keep its standing state in a more stabilized way than ever.

Specifically, the heel mounting mechanism used in the present invention may be constructed in such a manner that the heel section can incline right and left with respect to the shin section as the shin section is seen from the tiptoe side (in other word, as the shin section is seen from the tiptoe side when the foot sections are installed on the setting surface). In this way, even if the shin section is inclined in a lateral direction, the bottom face of the heel section can always be in contact with the setting surface according to how the heel is inclined with respect to the shin section. As a more specific example of the heel mounting mechanism, the heel mounting mechanism may include a shaft orthogonal to a longitudinal direction of the shin section and extending in a direction where the tiptoe section and the heel section are disposed side by side so that the heel section can swing in a predetermined angular range with respect to the shaft. In this arrangement, the heel mounting mechanism can be constituted by merely a few number of components. Alternatively, in this case, if the shaft is constituted integrally with the heel section and the shin section includes a shaft supporting structure rotatably supporting the shaft, the heel mounting mechanism can be easily assembled.

The heel mounting mechanism may be constituted in such a manner that the heel section can be inclined back and forth with respect to the shin section as the shin section is seen from the tiptoe side. In order to realize the foregoing movement, the heel section may be attached to the shin section using a spherical portion and a spherical seat as shown inFIGS. 1 through 3of the Utility Model Registration Publication No. 3079299, for example. Even if configured in this way, in the present invention, a part of the tiptoe section is in contact with the setting surface independently of the heel section. Therefore, the heel mounting mechanism does not move even when a slight external force is applied.

The toy foot structure of the present invention can be applied to a transformable toy, the figure of which can be changed from a state where a toy doll is riding on a movable toy (such as a two-wheeled vehicle) to a toy robot having a configuration different from that of the toy doll by transforming a part of the movable toy and mounting it on the toy doll. In the transformable toy, the movable toy includes at least a pair of shin section constituents composed of one or more components and attached to a pair of leg sections of the toy doll to constitute shin sections of the pair of leg sections for the toy robot, and an assembly composed of a plurality of components and attached to an upper body of the toy doll to constitute an exterior for an upper body of the toy robot. Preferably, the assembly includes a first assembly constituent section mainly disposed in a front side of the toy doll; a second assembly constituent section connected to the first assembly constituent section and disposed in a back side of the toy doll; and a third assembly constituent section connecting the first and second assembly constituent sections. Each of the first, second and third assembly constituent sections are composed of the one or more components. The first, second and third assembly constituent sections are preferably assembled together in an annular shape to constitute the exterior of the toy doll. The exterior surrounds at lest shoulders, a crotch, the front side and the back side of the toy doll. In such a transformable toy as described above, the pair of shin section constituents are deformably constituted to form a toy foot structure that includes a shin section and a foot section having a tiptoe section and a heel section for the toy robot. In this way, the exterior having a sense of robustness can be firmly mounted onto the upper body of the toy doll. Still more, since the head section exposed from the third assembly constituent section works as a positioning means and a movement preventing means at the time of attaching the assembly to the toy doll, such an advantage can be obtained that the assembly can easily be attached to the toy doll. If the pair of the shin section constituents are mounted onto the toy doll, even when the upper body of the toy doll is equipped with a comparatively big exterior, it becomes possible to make a good balance between a weight of the lower body of the toy robot and a weight of the upper body of the toy robot. As a result, stability of the toy robot can be increased.

In the transformable toy, the toy foot structure of the present invention is employed as a heel mounting mechanism that attaches the heel section to the shin section. Namely, the heel mounting mechanism is constructed in such a manner that the heel section can move with respect to the shin section so that a whole bottom face of the heel section can be in full contact with a setting surface whenever the pair of leg sections of the toy robot are opened right and left, or closed, as seen from the front. In this manner, even when the toy robot having a heavily mounted upper body is installed on the setting surface with its leg sections opened, it is possible to keep the toy standing in a stabilized condition.

Alternatively, in the present transformable toy, if the heel mounting mechanism includes a shaft orthogonal to a longitudinal direction of the shin section and extending in a direction where the tiptoe section and the heel section are disposed side by side so that the heel section can swing in a predetermined angular range with respect to the shaft, the movement of the heel section is restrained by the shaft. Therefore, a configuration for fixing the shin section, the tiptoe section and the heel section in a predetermined shape in order to constitute a part of the movable toy can be simplified.

When the movable toy is autobicycle, each of two wheels of the autobicycle has a construction that can be divided into two parts in a direction orthogonal to the wheel's axle to form wheel half portions. The wheel half portions of the two wheels are mounted onto the exterior and/or both of the shin sections of the toy robot respectively. In this manner, the tires can be mounted onto the toy robot as if they were a part of armor of the toy robot. As a result, an image of the autobicycle before transformation can considerably be faded out and deformation degree of the transformable toy can be further increased.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will now be described in detail hereinafter by referring to the accompanying drawings.FIGS. 1A through 1Dare a side elevation view, front elevation view, back elevation view, and plan view of a transformable toy1of the present invention. A transformable toy1is transformed from a toy doll5riding on an autobicycle (movable toy)3into a toy robot (FIG. 3) having a configuration different from that of the toy doll5by disassembling and transforming a part of the autobicycle3and mounting it onto the toy doll5.FIGS. 2A through 2Care a side elevation vie w, front elevation view, and plan view of the autobicycle3.FIGS. 3A and 3Bare perspective views of an after-transformed toy robot23as seen diagonally from an upper right and lower left respectively, andFIGS. 4A through 4Care a front elevation view, left side view, and plan view of the toy robot23.

In these views, the autobicycle (movable toy)3has two wheels7and9, a chassis13provided with a fuel tank11and an engine12, a front fork14, a front cover15, a handle16, a rear cover17, a tire cover18, two muffler constituent sections19and21provided respectively with a step part20, accessories6, and a sitting portion8. An example of the accessories6is a machine gun, and can be disassembled into a plurality of components.FIG. 1shows a simplest example of accessories6andFIG. 2shows a constitution of the accessories6that constitutes a machine gun. The back wheel9is supported in a sandwiched relation between the two muffler constituent sections19,21. The two muffler constituent sections19,21have a fitting recess19arespectively on their side faces for receiving wheel half portions (9A,9B) which are constituted by dividing the wheel9into two, as will be explained later.FIGS. 3 and 4illustrate only one9B of the wheel half portions. The wheel7on the front side is also constituted by assembling wheel half portions (7A,7B) which respectively correspond to a half of the wheel. As shown inFIGS. 3 and 4, the wheel half portions7A and7B are mounted onto the toy doll5by use of a fitting structure on the side faces of the shoulders of the toy doll5, respectively.

A handle16disposed behind the front cover15includes a pair of arm parts16A,16B. As will be explained later, the pair of arm parts16A and16B have a pair of raised portions16aand16b(engaging portions) arranged integrally on end portions thereof that are engaged with a pair of recesses17aand17b(engaged portions) arranged on both sides of the rear cover17. The pair of arm parts16A,16B are constituted to rotate or move up and down, and also right and left. The pair of arm parts16A,16B will be loaded respectively on the both shoulders of the toy doll5after transformation.

In this embodiment, the two muffler constituent sections19,21constitute a pair of shin section constituents which constitute shin sections22A,24A of leg sections22,24of the toy robot23when the muffler constituent sections19,21are mounted onto the leg sections of the toy doll5as shown inFIGS. 3 and 4. The fuel tank11, engine12, chassis13, front fork14, front cover15, handle16, and rear cover17constitute an assembly which will be assembled in an annular shape and transformed into an exterior30for surrounding shoulders5d, a front side5e, a crotch5gand a back side5fof the doll body (upper body of the doll) except leg sections5c, arm sections5b, and a head section5aof the toy doll5.

The fuel tank11is constituted by two tank half portions11A,11B which are assembled together in such a manner that the tank half portions can be separated apart right and left, as will be explain in detail later. The two tank half portions11A,11B are rotatably attached to a rear frame13B so that a front frame13A, which will be described later, can pass through between the two tank half portions11A and11B that are divided right and left into two parts. The engine12includes a pair of engine constituent parts12A,12B mounted to the chassis13. The chassis13includes the front frame13A and the rear frame13B, as shown inFIG. 2. The front frame13A and the front fork14are connected to each other to rotate in a predetermined angular range. The rear frame13B and the rear cover17are connected to each other to rotate in a predetermined rotation range. In this manner, the number of rotatable connecting components in the annular exterior30, which will be mentioned later, increases, and consequently transformation of the annular exterior becomes easy.

Hereinafter will be described the transformation process from the state shown inFIG. 1into the toy robot as shown inFIGS. 3 and 4. First, inFIG. 1, the toy doll5is dismounted from the autobicycle3, and a front wheel7is removed from the front fork14. Next, one of the muffler constituent sections19,21is dismounted, and then a back wheel9is removed from the other muffler constituent sections19,21. The remaining muffler constituent section is then dismounted. The accessories6and the engine constituent parts12A,12B are removed.FIG. 5Ashows a figure as described above.FIG. 5Ais a configuration of the assembly to be used for constituting the exterior30which will be mounted onto the upper body of the toy doll5.

Next, as shown by thick arrows inFIG. 5A, the arm parts16A,16B of the handle16are rotated upward, and they are changed into a figure as shown inFIG. 5B. The tank half portions11A,11B of the fuel tank11are opened right and left as shown inFIGS. 6A and 6B. A clearance G which is formed between the two tank half portions11A,11B has such a width dimension as the front frame13A can pass through the clearance (or the two tank half portions11A,11B may rotate counterclockwise along both sides of the front frame13A).

Next, as shown inFIG. 7A, the front cover15is rotated counterclockwise until the engagement between the front cover15and the fuel tank11is released, then the two tank half portions11A,11B are rotated counterclockwise along both sides of the front frame13A as shown inFIG. 7B. The rear cover17is rotated clockwise with respect to the rear frame13B. Two front forks14are bent inside at the middle portion at that time. The front fork14has a configuration in which two fork parts14A and14B are connected via a rotating mechanism. A cover part17A of the rear cover17, which is located by the side of the sitting portion, is supported by a rear cover body17B in such a manner that the cover part can be turned over. The turned-over face of the cover part17A has an engaging portion17C that engages with an engaged portion (refer to the part shown inFIG. 9:5h) arranged in the toy doll as will be mentioned later.FIG. 7(B)shows the cover member17A which has been turned over.

In assembling the annular exterior30, the front cover15and the front frame13A are further rotated to the extent that the raised portions16aand16barranged at the end portions of the pair of arm parts16A,16B of the handle16fit into the recesses17a,17barranged in rear cover17, as shown inFIG. 8A.FIG. 8Bshows the annular exterior30which has been completely assembled.

In order to mount the exterior30onto the toy doll5, the toy doll5is inserted in an interior of the exterior30before connecting the pair of arm parts16A,16B of the handle16to the rear cover17as shown inFIGS. 9 and 10. The toy doll is arranged so that the crotch of the toy doll5may ride on the front frame13A, and the pair of arm parts16A,16B may be disposed on both shoulders of the toy doll5. The engaged portion5hformed of a fitting recess arranged in the back of the toy doll5is engaged with the pin-shaped engaging portion17C arranged on the turned-over face of the cover part17A of the rear cover17located by the side of the sitting portion at this time. In this manner, positioning of the toy doll5with respect to the exterior30is completed. As a result, unnecessary loosening between the toy doll5and the exterior30can be prevented.

After mounting the exterior30onto the toy doll5, as shown inFIGS. 3 and 4, the accessories6are then mounted onto both arm sections of the toy doll5respectively, the wheel half portions7A,7B of the wheel7are mounted onto the shoulders of the toy doll5respectively, and the engine constituent parts12A,12B are mounted onto both sides of the front frame13A via the fitting structure respectively.

In the foregoing embodiment, a first assembly constituent section includes the front cover15, front fork14, and front frame13A of the autobicycle. The first assembly constituent section is disposed mainly in a front side5eof the toy doll5. The second assembly constituent section includes the fuel tank11, the sitting portion8, the rear frame13B, and the rear cover17. The second assembly constituent section is connected to the first assembly constituent section and disposed in a back side5fof the toy doll5. The third assembly constituent section includes the handle16. The third assembly constituent section works to connect the first and second assembly constituent sections.

Next, the shin sections and the foot sections of the leg sections of the toy doll5are inserted into holes of the two muffler constituent sections19,21. The holes are formed at the end portions near step portions20respectively. The other end portions (opposite to the end portions near the step portions20) of the two muffler constituent sections19and21are provided with components26for constituting heel sections25and components28for constituting tiptoe sections27of the foot sections in a transformable way for the case of using muffler constituent sections19,21as shin sections22A,24A and as the foot sections of the toy robot23.

FIGS. 11A and 11Brespectively show a side elevation view and a back elevation view in a state where the muffler constituent section19is transformed to constitute the leg section22of the toy robot23.FIG. 12Ashows a sectional view taken along line VIA-VIA ofFIG. 11A, andFIG. 12Bshows a sectional view taken along line VIB-VIB ofFIG. 11B. A muffler constituent body19A of the muffler constituent section19is constituted by assembling two mold half portions. As well shown inFIG. 12B, a partition wall19C, which has a wall part19B extending in a vertical direction (a longitudinal direction of the shin section22A) of the constituent body19A, is formed in the interior of the constituent body19A which constitutes the shin section22A of the toy robot23. On the wall part19B is arranged a shaft31orthogonal to the wall part19B (orthogonal to the longitudinal direction of the shin section) and extending in a direction in which the component28for constituting the tiptoe section27and the component26for constituting the heel section25are disposed side by side. The shaft31is arranged integrally with the component26for constituting the heel section25. The component26for constituting the heel section25is constituted by two mold half portions including the portion which constitutes the shaft31. Since the shaft31is rotatably supported by the wall part19B, the components26for constituting the heel section25can swing right and left in a predetermined angular range with respect to the shaft31.

A raised portion33for fitting into the end portion of the leg section of the toy doll5is arranged on a side wall19D of the partition wall19C extending in a lateral direction. At the end portions of the leg sections of the toy doll5, a fitted hole is formed where the raised portion33is received.

The component28for constituting the tiptoe section27is rotated on a shaft37of which ends are fixed to a pair of opposed side walls of the constituent body19A.FIG. 11shows the component28for constituting the tiptoe section which27has been rotated 90 degrees. In this state, a portion35of the constituent body19A which constitutes the shin section22A opens forward, and the end portion thereof is disposed on the component28for constituting the tiptoe section27. The portion35of the constituent body19A is connected to the constituent body19A via a conventional hinge mechanism.

Between the component26for constituting the heel section25and the pair of opposed side walls of the constituent body19A, a clearance g is formed (refer toFIG. 13), thereby allowing the component26to swing in the predetermined angular range with respect to the shaft31. A width of the clearance g is determined based on an intended angle range by which the toy robot23opens (inclines) its pair of leg sections (19,21) laterally (in the right and left direction when the toy robot23is seen from the front).FIG. 13conceptually shows that the heel section25can have its bottom face in full contact with a setting surface38even when the leg sections22,24of the toy robot are inclined in the lateral or right/left directions. The leg sections of toy robot23can be opened in the right and left direction wider until the components26for constituting the heel section s25and the side walls of the constitution body19A,21A which constitute the shin sections22A,24A of the toy robot23contact with each other. Therefore, the above-mentioned clearance g is arbitrarily determined based on the opening angle of the leg sections.

A heel mounting mechanism according to the present embodiment is theoretically constituted by the shaft31and the wall part19B rotatably supporting the shaft31. The wall part19B constitutes a shaft supporting structure. The heel mounting mechanism is constructed in such a manner that the heel sections25can move with respect to the shin sections (22A,24A) so that the whole bottom faces of the heel sections25can be in full contact with the setting surface whenever the pair of leg sections22,24of the toy robot23are opened right and left, or closed, as seen from the front. In this manner, even when the toy robot having a heavily mounted upper body is installed on the setting surface38with the legs opened, it is possible to keep the toy standing in a stabilized condition.

The heel mounting mechanism may be constructed so that the heel sections25can be inclined back and forth with respect to the shin sections as the shin sections are seen from the tiptoe side. In order to realize such a movement, as conceptually shown inFIG. 14, the heel mounting mechanisms are constructed using spherical portions39,39which are integrally arranged on the components26for constituting the heel sections25and spherical seats41,41arranged in the constituent bodies (19A,21A) for rotatably receiving the spherical portions39. Even if constructed in this way, since a part of the tiptoe sections27contact the setting surface independently of the heel sections25and a movement of the heel sections25is controlled because the pair of opposed sidewalls of the constituent bodies (19A,21A) contact the heel sections25, the heel mounting mechanisms is not moved unfavorably even if some external force is applied.

The two wheels7,9of the autobicycle can be divided into two (can be halved) in the direction orthogonal to the axle according to the above-mentioned embodiment. The wheel half portions, which are constituted by dividing the two wheels into two, are mounted onto both of the shoulders and both of the shin sections of the toy robot. One of the wheel half portions is omitted from the illustration. Since the wheels can be mounted onto the toy robot like a part of armor for the toy robot in this manner, an image of the autobicycle before transformation can be considerably faded out and transformation degree of the transformable toy can be further increased. Although the autobicycle is used as the movable toy according to the above-mentioned embodiment, the present invention can also be applied to a transformable toy using other movable toys such as an airplane and a vessel. In the above-mentioned embodiment, although the toy foot structure of the toy robot capable of standing on two feet is employed in the present invention, the toy foot structure of the present invention may be applied to a foot structure for a toy robot having four legs, and the number of the legs is not limited.

INDUSTRIAL APPLICABILITY

According to the present invention, an unprecedented process of transformation can be enjoyed, and the assembly constituting a part of the movable toy is transformed into an unpredictable figure. Consequently, the interest of transformable toy lovers can be increased substantially.

The present invention also has such an advantage that even when the toy is installed on the setting surface with its legs opened right and left, the toy can maintain its standing state in a more stabilized condition than ever.
