DESCRIPTION OF EMBODIMENTS

Below, a robot toy of the present invention is described based on the illustrated embodiments.

FIG. 1 is a perspective view showing an embodiment of the robot toy, FIG. 2 is a conceptual exploded perspective view of main components in a robot toy main body, and FIG. 3 is a conceptual perspective view showing a main portion with a portion of the robot toy main body cut out.

<Schematic Configuration of Robot Toy>

This robot toy includes a robot toy main body 1 and a controller C. In the robot toy main body 1, a torso portion 20 is supported rotatable in a horizontal direction with respect to a hip portion 10, and an arm portion 30 is supported rotatable in a vertical direction with respect to the torso portion 20. Further, in the hip portion 10, a leg portion 40 is supported to be able to move forward. The robot toy main body 1 is operated by remote control using the controller C.

<Outline of Operation of Robot Toy Main Body>

The outline of the operation of the robot toy main body 1 of the robot toy is described below.

FIG. 1 shows a state of the robot toy main body 1 where the torso portion 20 is twisted to the right side with respect to the hip portion 10 and a sword A is positioned above a right shoulder. In other words, the sword A is held high above in the upper right. In this state, when a user holds the controller C and makes a large swing from a high position to a low position, the robot toy main body 1 swings the sword A downward while twisting the torso portion 20 to the left side and also moves the right side leg portion 40 forward. In this case, since the robot toy main body 1 swings the sword A downward while twisting the torso portion 20 to the left side, viewed from the front of the robot toy main body 1, it is as if the robot toy main body 1 swings down the sword A diagonally from above the right shoulder to below the left leg.

Then, when the user makes a small swing with the controller C with the tip of the controller C pointing down, the robot toy main body 1 moves the right side leg portion 40 forward according to the number of times the user swings the controller C in a state in which the torso portion 20 is twisted to the left side and the sword A is maintained swung downward.

Then, when the user swings the controller C largely from the low position to the high position in a state where the torso portion 20 is twisted to the left side and the sword A remains swung downward, the robot toy main body 1 swings the sword A upward while twisting the torso portion 20 to the right side and moves the left side leg portion 40 forward. In other words, the robot toy main body 1 returns to the state of FIG. 1.

Then, when the user makes a small swing with the controller C with the tip of the controller C pointing up, the robot toy main body 1 moves the left side leg portion 40 forward according to the number of times the user swings the controller C in a state in which the torso portion 20 is twisted to the right and the sword A is swung upward.

While the above operation progresses, a head portion 50 of the robot toy main body 1 constantly faces forward.

<Details of Configuration of Robot Toy Main Body>

Next, the details of the robot toy main body 1 is described.

The outline of the torso portion 20 includes a front portion cover 20a and a rear portion cover 20b shown in FIG. 2. A power transmission mechanism is stored in the torso portion 20.

As shown in FIG. 5A and FIG. 5B, the power transmission mechanism includes a speed reducing gear train 15 assembled in a casing 13.

In the speed reducing gear train 15, a pinion 15b fixed to an axis 16a of a motor 16 is meshed to a large diameter gear 15c, a small diameter gear 15d fixed to the same axis as the large diameter gear 15c is meshed to a large diameter gear 15e, and a final gear 15a is fixed to the same axis as the large diameter gear 15e. The final gear 15a of the speed reducing gear train 15 is externally exposed from the casing 13 as shown in FIG. 4.

The final gear 15a is meshed to the internal gear 17a formed in the inner perimeter face of the rotating disk 17.

Therefore, the power of the motor 16 is reduced by the speed reducing gear train 15, and the rotating disk 17 is rotated through the final gear 15a. The rotation of the rotating disk 17 is used for operating the torso portion 20, the arm portion 30, and the leg portion 40, described later.

A center portion of the casing 13 where the speed reducing gear train 15 is assembled penetrates through the rotating disk 17 and projects upward from the rotating disk 17. A projecting portion 13a is a cylinder, and the inside of the projecting portion 13a is hollow and open at the bottom. The motor 16 is provided in the hollow portion. As shown in FIG. 5A, a fixed axis 18A is provided fixed to the projecting portion 13a. A fixed gear 18 is formed on the fixed axis 18A.

As shown in FIG. 4, the head portion 50 is attached to the upper edge of the fixed axis 18A.

A protrusion 17b in a pillar shape is provided standing on the upper surface of the rotating disk 17 in a position corresponding to a back portion of the robot toy main body 1 when the rotating disk 17 is in a horizontal neutral position. A recess portion 18b is formed in the torso portion 20 supported rotatable in the horizontal direction with respect to the hip portion 10 and is engaged to the protrusion 17b. When the rotating disk 17 rotates, the protrusion 17b presses the edge of the recess portion 18b and the torso portion 20 is rotated in the same direction as the rotating disk 17.

As shown in FIGS. 6A and 6B, two notches 18B are formed in the fixed axis 18A separated from each other a predetermined distance in the perimeter direction in a portion directly above the fixed gear 18. A latching member 19 is attached to the inner face side of the torso portion 20. A latching piece 19a is formed in the latching member 19 to engage to the notch 18B. The latching member 19 is attached to the torso portion 20 so that the latching piece 19a faces the fixed axis 18A and is connected with pressure to the fixed axis 18A by the spring 19b. These compose the reverse rotation prevention mechanism.

The rotating range of the torso portion 20 is limited by, for example, a part of the rotating disk 17 or the torso portion 20 coming into contact with a stopper (not shown) provided in the hip portion 10. According to the present embodiment, as shown in FIG. 10, the range is limited by a lever 41 being stored in a cut-out 12a formed on both side faces of the base 12 of the hip portion 10 and striking the edge of the cut-out 12a. By limiting the rotating range, the position where the torso portion 20 is twisted maximum to the right side and the position where the torso portion 20 is twisted maximum to the left side is decided. At this position, the latching piece 19a engages to one of the two notches 18B and the reverse rotation of the torso portion 20 is held. The hold of reverse rotation of the torso portion 20 is released when the torso portion 20 rotates in the reverse direction with the motor 16.

As shown in FIG. 3, the fixed gear 18 is meshed with the crown gear 31. The crown gear 31 is attached to the torso portion 20. Specifically, as shown in FIG. 8, a circular recess portion 31b is formed in an axis portion 31a of the crown gear 31 to be concentric to the axis portion 31a. The circular recess portion 31b is held rotatable between the front portion cover 20a and the rear portion cover 20b and with this, the crown gear 31 is attached to the torso portion 20. Alternatively, a boss can be provided in a portion corresponding to the right shoulder on the inner side of the torso portion 20 and a position which does not disturb the rotation of the torso portion 20. A rivet made of iron, etc. can be provided in the crown gear 31 to penetrate a center of rotation of the crown gear 31 from the outside toward the inside. This rivet can be hit in the boss in the torso portion 20 to attach the crown gear 31 to the torso portion 20. In this attached state, the crown gear 31 is meshed to the fixed gear 18 and the crown gear 31 rotates itself while rotating around the fixed gear 18 together with the rotation of the torso portion 20.

Then, as shown in FIG. 7B, at least one (in the present embodiment, three) bump portion 31c is formed on an outer perimeter in the portion projecting outside from the torso portion 20 of the axis portion 31a of the crown gear 31. As shown in FIG. 7A, a base portion 32 of the arm portion 30 is formed in a circular shape. A slit 32a is formed in the base portion 32, and with this, the base portion 32 can be enlarged easily to open in the radius direction by elasticity. A large number of recess portions 32b are formed in a perimeter direction in the inner perimeter face of the base portion 32.

Then, as shown in FIG. 8, the axis portion 31a of the crown gear 31 is fitted by pressing into the base portion 32 of the arm portion 30. In this case, when the user desires to adjust the position of the rotating direction of the arm portion 30, the base portion 32 is forcibly rotated. With this, the base portion 32 is enlarged by being deformed elastically and rotates past the bump portion 31c of the crown gear 31. Another recess portion 32b fits to the bump portion 31c and is latched there.

In this case, it is preferable to set the number of teeth of the crown gear 31 and the number of recess portions 32b of the inner perimeter face of the base portion 32 to a same number or to set the number of recess portions 32b of the inner perimeter face of the base portion 32 to a multiple number of the number of teeth of the crown gear 31. It is preferable that the number of recess portions 32b of the inner perimeter face of the base portion 32 is an integral multiple number of the bump portion 31c. With this, it is possible to suitably adjust the initial position of the arm portion 30. If this is not suitably adjusted, it is not possible to fully swing down the sword A.

The leg portion 40 is provided on both side portions of the hip portion 10. Inside the leg portion 40, as shown in FIG. 9A and FIG. 9B, the lever 41 extends in the vertical direction. This lever 41 is supported in a central portion to be able to rock with the axis 41a as the center. This lever 41 is biased in the counterclockwise direction as shown in FIG. 9A with the spring 42.

A front wheel 43 is attached to the lower half portion of the lever 41. A rachet wheel 44 is attached to the inner face of the front wheel 43 as one with the same axis. An axis 45 of the front wheel 43 and the rachet wheel 44 is inserted in a long hole 41b formed on a lower edge portion of a lever 41, and the axis 45 is movable and rotatable in the long hole.

A pawl member 46 is attached to a bottom portion of the lever 41. A pawl 46a of the pawl member 46 is provided opposing to the rachet wheel 44.

A rear wheel 47 is provided in a rear edge bottom portion of the leg portion 40.

In the initial position, an upper edge of the lever 41 is positioned to the rear by the bias force of the spring 42 (FIG. 9A). In this position, when the force F is applied to the upper edge of the lever 41 from the rear, the lever 41 resists the bias force of the spring 42 and rotates around the axis 41a as the center in a clockwise direction as shown in the diagram. Here, the front wheel 43 is pressed hard against the floor, the axis 45 of the front wheel 43 moves in a direction of the pawl 46a of the pawl member 46 in the long hole 41b, and the pawl 46a of the pawl member 46 meshes with the teeth of the rachet wheel 44 to lock the front wheel 43. As a result, with the operation of the lever 41, the front wheel 43 kicks the floor, and the leg portion 40 corresponding to the lever 41 moves forward (see FIG. 9B).

Then, when the force F applied to the upper edge of the lever 41 is removed, the lever 41 rotates around the axis 41a as the center with the bias force of the spring 42 in a counterclockwise direction as shown in the drawing. Here, the movement of the axis 45 of the front wheel 43 becomes later than the movement of the pawl 46a of the pawl member 46 by the long hole 41b, the pawl 46a of the pawl member 46 releases the mesh with the teeth of the rachet wheel 44 so that the front wheel 43 becomes free, the front wheel 43 rolls and the leg portion 40 corresponding to the lever 41 maintains a stopped state.

The front wheel 43 and the rachet wheel 44 are supported by an axis at the long hole 41b, and the pawl 46a of the pawl member 46 is opposed to the teeth of the rachet wheel 44. With this, a one-way crutch mechanism is configured and the robot toy main body 1 can run effectively.

The lever 41 operates by the rotation of the rotating disk 17. As shown in FIG. 10, the lever 41 is stored in the cut-out 12a formed on both side faces of the base 12 of the hip portion 10. As shown in FIG. 6B and FIG. 10, protrusion 17c which is a contact portion for operating the lever is formed in the perimeter face of the rotating disk 17. When the rotating disk 17 is rotated, the lever 41 is pressed by the protrusion 17c and the lever 41 resists to the bias force of the spring 42 and is operated.

Next, the internal configuration of the controller C is described.

A circuit configuration of the robot toy main body 1 is shown in FIG. 12. The robot toy main body 1 includes a control device 61, a receiving unit 62, a power source switch 63, and the motor 16. The control device 61 obtains an operation control signal from the controller C through the receiving unit 62, and controls operation of the robot toy main body 1 through the motor 16 based on the operation control signal.

Specifically, the control device 61 swings the sword A or moves the leg portion 40 forward according to how the user swings the controller C. Here, after the control device 61 operates the motor 16 for an amount of time that power is necessary, the motor 16 is stopped.

<Configuration of Controller C>

As shown in FIG. 13, the controller C includes a control device 71, a transmitting unit 72, an acceleration sensor 73, and various switches 74.

According to a program, the control device 71 judges how the user swings the controller C based on a signal detected by the acceleration sensor 73. Then, the control device 71 controls the transmitting unit 72 to transmit an operation control signal according to how the swing is to the robot toy main body 1. Alternatively, the control device 71 can transmit the operation control signal from the transmitting unit 72 to the robot toy main body 1 according to operation of the various switches 74, regardless of whether the user swings the controller C.

The controller C can also include a speaker. In this case, according to a program, the control device 71 can output sound from the speaker when the robot toy main body 1 moves forward or when the user swings the sword A.

The controller C can also include a charger for the robot toy main body 1.

<Details of Operation of Robot Toy Main Body>

The robot toy main body 1 of the present embodiment operates as described below.

In the robot toy main body 1, when the user swings the controller C, the robot toy main body 1 operates based on how the swing is.

In other words, when the user largely swings down the controller C, the movement is detected by the acceleration sensor 73 included in the controller C, and the motor 16 of the robot toy main body 1 rotates the rotating disk 17 in a counterclockwise direction from a planar view.

Then, as shown in FIG. 11A, in the robot toy main body 1, the protrusion 17c presses the right side lever 41, moves the upper edge portion of the right side lever 41 to the front (shown by an alternate short and long dash line), and with this, the right side leg portion 40 moves forward one step. During the above, the torso portion 20 rotates with the protrusion 17b of the rotating disk 17, and the crown gear 31 rotates around the fixed gear 18 while rotating itself. With this, the sword A is swung down. In this case, since the torso portion 20 rotates and the sword A is swung down, the sword A is swung down diagonally when viewed from the front. When a predetermined amount of time passes, the motor 16 is stopped.

When the motor 16 is stopped, since the force F pressing the lever 41 is released, the lever 41 returns to the initial position by the bias force of the spring 42 of the leg portion 40. With this, the lever 41 presses the protrusion 17c and the rotating disk 17 is reversely rotated. Here, the protrusion 17b of the rotating disk 17 rotates reversely with the rotating disk 17 as shown by the solid line in FIG. 11A. However, since the protrusion 17b moves only within the recess portion 18b, the torso portion 20 where the recess portion 18b is formed does not return.

When the swung down controller C is swung up, the motor 16 rotates reversely. When the motor 16 rotates reversely, the rotating disk 17 rotates in the clockwise direction from a planar view. Then, as shown in FIG. 11B, the torso portion 20 rotates in the clockwise direction, the protrusion 17c comes into contact with the left side lever 41, the upper edge portion of the left side lever 41 is moved forward (shown with a short and long dash line) and the left side leg portion 40 moves one step. During the above, the torso portion 20 rotates through the protrusion 17b of the rotating disk 17, and the crown gear 31 rotates around the fixed gear 18 while rotating itself. With this, the sword A is swung up. When a predetermined amount of time passes, the motor 16 is stopped.

In this case also, when the motor 16 stops, since the force F pressing the lever 41 is released, the lever 41 returns to the initial position by the bias force of the spring 42 of the leg portion 40. With this, the lever 41 presses the protrusion 17c and the rotating disk 17 is reversely rotated. Here, the protrusion 17b of the rotating disk 17 rotates reversely with the rotating disk 17 as shown by the solid line in FIG. 11B. However, since the protrusion 17b moves only within the recess portion 18b, the torso portion 20 where the recess portion 18b is formed does not return.

In the robot toy main body 1, when the user makes a small swing of the controller C in a state where the tip of the controller C is pointing down, the rotating disk 17 rotates in the counterclockwise direction from a planar view from the state of the protrusion 17b in a solid line as shown in FIG. 11A. Therefore, again, the protrusion 17c presses the right side lever 41 to move the upper edge portion of the right side lever 41 forward (shown with alternate long and two short dash line), and with this, the right side leg portion 40 moves forward one step. When the user makes a small swing of the controller C in a state where the tip of the controller C is pointing up, the rotating disk 17 rotates in the clockwise direction from a planar view from the state of the protrusion 17b in a solid line as shown in FIG. 11B. Therefore, again, the protrusion 17c presses the right side lever 41 to move the upper edge portion of the left side lever 41 forward (shown with alternate long and short dash line), and with this, the left side leg portion 40 moves forward one step.

Embodiments of the present invention are described above, however, the present invention is not limited to the above embodiments, and various modifications are possible without changing the scope of the present invention.

For example, the present embodiment is a robot toy main body 1 which swings down and swings up a sword A. However, the present invention can be applied to a robot toy body which brings out and pulls back its fist, a robot toy body which slaps like a sumo wrestler or toy main bodies other than a robot toy main body.

According to the present embodiment, only the right side arm portion 30 moves together with the motor 16 through the crown gear 31 and the left side arm portion 30 follows. However, both arm portions 30 can move together with the motor 16. In this case, each arm portion 30 can move individually, and it is possible to make a robot toy main body such as a robot toy main body which can use two swords, or a robot toy main body which can do dance movements.

According to the above embodiment, the torso portion 20 is supported rotatable with respect to the hip portion 10 and the arm portion 30 is supported rotatable with respect to the torso portion 20. However, the arm portion 30 can be fixed to the torso portion 20.

The present invention can be suitably used in the field of manufacturing toys such as a robot toy.

The toy as recited in claim 8, wherein each of the first leg and the second leg is provided with a propulsion mechanism having a wheel to kick a support surface so that the respective first or second leg moves forward, the propulsion mechanism including: a lever which extends in a substantially vertical direction at each of the first leg or the second leg and which is supported rotatably by a second axis so that a lower edge portion of the lever moves in a forward and rearward direction;the wheel is provided at the lower edge portion of the lever;a one-way clutch mechanism which locks the wheel when the lower edge portion of the lever moves in the rearward direction and which releases the lock of the wheel when the lower edge portion of the lever moves in the forward direction; andthe spring biases the lever so that the lower edge portion of the lever is biased in the frontward direction,wherein the contact portion of the rotating disk presses an upper edge portion of the lever of only one of the first leg or the second leg according to the first or second rotating direction of the rotating disk and moves the lever against the bias force of the spring to move the pressed leg into the second, extended position.

10. The toy as recited in claim 9, further comprising a reverse rotation prevention mechanism connected to the torso to prevent reverse rotation of the torso in a position where the lower edge portion of the lever finishes moving in the rearward direction, and until the motor reversely rotates the torso.

11. The toy as recited in claim 10, further comprising: a fixed gear in the torso; anda crown gear provided at the arm,wherein the crown gear meshes with the fixed gear and rotates with the fixed gear and a rotation of the torso so that the arm moves.

12. The toy as recited in claim 11, further comprising, an engaging portion on the crown gear includes at least one of a bump portion or at least one of a recess portion; andan engaging portion on the arm includes the other of the at least one bump portion or the at least one recess portion to engage the one of the at least one bump portion or the at least one recess portion of the crown gear engaging portion,wherein a number of the at least one bump portion or a number of the at least one recess portion is a same number as a number of teeth of the crown gear or a multiple of the number of teeth of the crown gear.

13. The toy as recited in claim 11, wherein a sword is attached to a hand of the arm.
