Description

  The present invention relates to a traveling toy that can automatically change the direction of travel of a toy body when the progress is blocked by an obstacle.

  2. Description of the Related Art Conventionally, a traveling toy that can automatically change the traveling direction of a toy body when it is blocked by an obstacle is known (see, for example, Patent Document 1).

  This conventional traveling toy includes a toy body provided with a power source, a rotating shaft that is rotated by the power of the power source, a rotating shaft that is inserted in a relatively rotatable manner, and horizontally in accordance with the rotation of the rotating shaft. A rotating body that is rotatable, a driving wheel that is supported by the rotating body and that is driven as the rotating shaft is rotated, and an idle wheel that is supported by the toy body, are configured to prevent progress by an obstacle. When the rotation of the drive wheels is restricted, so-called mystery traveling is possible in which the rotating body rotates to automatically change the traveling direction of the toy body.

  Here, the mystery traveling of the conventional traveling toy will be specifically described. FIG. 11 is a diagram for schematically explaining a direction changing operation at the time of collision of a conventional traveling toy, and is a partial cutaway view of the traveling toy viewed from above. In the figure, 101 represents a toy body, 105 represents a rotating body, 107 represents a drive wheel, and 142 represents a rotation axis. First, as shown in FIG. 11 (a), when the traveling toy is traveling straight, a force acts on the rotating body 105 in the counterclockwise direction indicated by the dotted arrow. 105 is stopped and only the driving wheel 107 is rotating. And as shown in FIG.11 (b), when it collides with the wall surface W, while the drive wheel 107 will continue to rotate, it will be regulated by the frictional resistance with a floor, and while the rotary body 105 rotates counterclockwise, The toy main body 101 also rotates so as to avoid the wall surface W (FIG. 11C). And as shown in FIG.11 (d), the direction which the toy main body 101 advances changes with the direction of the drive wheel 107 changing. The direction change of the traveling toy at the time of the collision from FIG. 11 (b) to FIG. 11 (d) is performed instantaneously. Thus, the traveling toy having the mystery traveling function automatically changes the traveling direction of the toy body 101 when the traveling toy is blocked by an obstacle.

Japanese Utility Model Publication No. 45-10346

  However, in a conventional traveling toy capable of mystery traveling, when the driving wheel 107 is in contact with the ground, the rotating body 105 stops and only the driving wheel 107 rotates due to the weight of the traveling toy, but the toy body 101 is lifted. Since the rotating body 105 rotates, there is a possibility that an operating noise may be generated, or in some cases, it may be dangerous when it is applied to the palm of the hand, and a cord or the like may be further involved.

  In addition, if the toy body 101 comes into contact with the side wall or the rail when the toy body 101 comes into contact with the side wall or the rail, the rotating body 105 rotates on the course by the mystery traveling function. There was a problem that could not run forward. In recent years, there are various ways to play traveling toys, and traveling toys capable of various traveling such as traveling on a flat floor or table or traveling on a course have been desired.

  The present invention has been made in view of the above-described circumstances, and its purpose is to automatically change the direction of travel of the toy body when the progress is blocked by an obstacle, and the toy body is lifted.

  According to the invention described in (1) above, the rotation of the rotating body is restricted even when the toy body is lifted by the rotation restricting means acting on the cam mechanism of the rotating body. Thereby, generation | occurrence | production of the operation | movement sound by the rotation of a rotating body, or the entrainment of a string etc. can be prevented. Even if the driving wheel of the toy body is grounded, the rotation of the rotating toy is regulated by the rotation regulating means in addition to the weight of the running toy unless the obstacle is blocked by the obstacle, Improves. As a result, even when running on a course with side walls on the left and right, or with a rail, the running toy does not rotate by simply touching the side wall or rail, so that the running toy can be run and played on the course. Furthermore, since the rotation restricting member acts on the cam mechanism provided on the rotating body, the movement of the traveling toy can be controlled by the shape of the cam mechanism.

  According to the invention described in (5) above, the rotation restricting means acts on the rotating body, whereby the rotation of the rotating body is restricted even when the toy body is lifted. Thereby, generation | occurrence | production of the operation | movement sound by the rotation of a rotating body, or the entrainment of a string etc. can be prevented. Even if the driving wheel of the toy body is grounded, the rotation of the rotating toy is regulated by the rotation regulating means in addition to the weight of the running toy unless the obstacle is blocked by the obstacle, Improves. As a result, even when the vehicle has a side wall on the left and right or runs on a course with rails, the traveling toy does not rotate by simply touching the side wall or rail, so that the running toy can be run and played on the course. Furthermore, since the rotation restricting means acts on the rotating body without using the gear mechanism, the number of parts can be reduced, and the manufacturing cost can be reduced by simplifying the structure.

  According to the invention as described in said (6), rotation of a rotary body can be controlled with a simple structure.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing the appearance of a traveling toy according to an embodiment of the present invention, FIG. 2 is a plan view seen from the back side of the traveling toy in FIG. 1, and FIG. 4 is a schematic view of the interior of the traveling toy as viewed from one side in the front-rear direction. FIG. 5 is a schematic view of the traveling toy as viewed from above with a part cut away. Is a state where the cam is stopped when the traveling toy is traveling forward, and (b) is a state where the cam is rotating at the time of collision.

  As shown in FIG. 1, the traveling toy 10 has an animal shape in appearance, and mainly includes a front part 2 in which a face 21 and a chest 22 are integrally formed, a head 31 and four legs. The toy body 1 is formed by the body portion 3 in which the body 32 and the body 33 are integrally formed, and a motor M (see FIG. 3) as a power source, a battery (not shown), and the like are accommodated therein. The front surface portion 2 is fixed to the body portion 3 by two screws 23 from the front, and the inside can be accessed by removing the screws 23. In the present embodiment, the appearance is an animal shape, but the present invention is not limited to this, and any shape such as a vehicle, a train, a ship, a human being, a plant, or the like can be adopted.

  As shown in FIG. 2, a substantially circular opening 35 is formed at a substantially central portion in the width direction in front of the rear surface of the body portion 3, and a rotating body 5 is provided in the opening 35 so as to be rotatable with respect to the body portion 3. It is done. In addition, a pair of idle wheels 6 are provided on both rear legs 32 of the body portion 3. Power from the motor M is not transmitted to the idle wheel 6, and the idle wheel 6 is configured to rotate following the rotation of a drive wheel 7 provided on the rotating body 5 described later.

  The motor M is disposed in the space of the toy main body 1 and can be driven by electric power from a battery (not shown). This battery can be replaced by removing the back cover 37 shown in FIG. The power of the motor M is transmitted to the drive wheel 7 via the power transmission mechanism 4 as shown in FIGS. The power transmission mechanism 4 includes a bevel gear 41 attached to the output shaft of the motor M, a rotary shaft 42 orthogonal to the output shaft of the motor M, and a bevel gear 41 attached to the upper end of the rotary shaft 42. A bevel gear 43 that meshes with the rotation shaft 42, a crown gear 44 that is attached to the lower end of the rotation shaft 42, an axle 45 that is orthogonal to the rotation shaft 42 and disposed in the horizontal direction, and a gear that is provided on the axle 45 and meshes with the crown gear 44. 46, the power of the motor M is transmitted to the drive wheel 7 via the bevel gear 41 → the bevel gear 43 → the rotary shaft 42 → the crown gear 44 → the gear 46 → the axle 45, and the pair of drive wheels 7 Rotation drive.

  The pair of drive wheels 7 may be rotatably supported by the rotating body 5 and may be provided with rubber or the like to ensure a grip with the ground surface. In addition, if rubber or the like is mounted only on the wheel on the side that rotates forward in the rotation direction of the rotating body 5 and the other wheel is made of a resin that has a low resistance to the ground surface, the direction change during the mystery traveling can be further improved. It can also be smooth.

  The rotating body 5 has a columnar shape, and a rotating shaft 42 is inserted into a substantially center of the rotating body 5 so as to be relatively rotatable, and an axle 45 having a gear 46 meshing with a crown gear 44 attached to the lower end of the rotating shaft 42 is supported. By doing so, the drive wheel 7 is rotatably supported. The rotating body 5 is rotatable in the horizontal direction by the frictional force with the rotating shaft 42. This frictional force is set so that the rotating body 5 does not rotate due to the action of the traveling toy 10 such as its own weight when the driving wheel 7 is grounded.

  A cam mechanism 51 is integrally formed at the upper end of the rotating body 5 so as to surround the rotating shaft 42, and the cam mechanism 51 is also rotated when the rotating body 5 rotates. The toy main body 1 is given a biasing force so as to regulate the rotation of the rotating body 5 with a pin 11 (for example, see FIG. 5) protruding in the vertical direction inside the toy main body 1 as a fulcrum. An elastic member 12 is provided. In addition, although the rod-shaped spring was illustrated as the elastic member 12, not only this but well-known things, such as a plate-shaped spring, can be used.

  Here, the shape of the cam mechanism 51 will be described more specifically with reference to FIG. In FIG. 5, the symbol P is a line (hereinafter referred to as a center line) drawn along the traveling direction of the drive wheel 7 through the rotation axis 42 and the center O of the rotating body 5, and the symbol Q is vertical. Direction (direction perpendicular to the paper surface in FIG. 5) is a line drawn in a direction perpendicular to the center line P as viewed from above. The cam mechanism 51 has a substantially oval shape that is thin at the front and long at the rear and short when viewed from above. In addition, a linear portion 56 extending in parallel with the center line P is provided at a position offset from the center O on one side in the width direction. The linear portion 56 extends from the front side to the rear slightly from the center O, and the elastic member 12 is in contact therewith. The rotation of the rotating body 5 is regulated by contact.

  The outer peripheral edge of the cam mechanism 51 excluding the straight line portion 56 is formed by a smoothly continuous curved portion 57, and the curved portion 57 passes from the leading end portion 57a having a large curvature to the leading end portion 57a via the slow bending portion 57b having a small curvature. The rear end portion 57c has a smaller curvature and a larger curvature than the loosely curved portion 57b. The cam mechanism 51 is configured so as not to be stable even when the rotating body 5 rotates and the elastic member 12 comes into contact with the curved portion 57 other than the straight portion 56.

  Therefore, when the rotating body 5 tries to rotate slightly, the urging force of the elastic member 12 that contacts the linear portion 56 of the cam mechanism 51 exceeds the rotating force of the rotating body 5 and its rotation is restricted (FIG. 5A). . Further, when a relatively large rotational force acts on the rotating body 5 and the rotating force of the rotating body 5 surpasses the urging force of the elastic member 12, the rotating body 5 rotates counterclockwise and the curved portion 57 becomes the elastic member 12. The cam mechanism 51 starts to rotate while coming into contact with. At this time, since the distance from the center O of the rear end portion 57c of the cam mechanism 51 is short, the cam mechanism 51 is instantaneously rotated until the front end portion 57a faces rearward, and from there, the front end portion 57a further gets over the elastic member 12. Until just before (FIG. 5B), a predetermined time difference occurs due to the urging force of the elastic member 12 because the distance of the tip portion 57 a is long. And when the front-end | tip part 57a gets over the elastic member 12, the elastic member 12 will contact | abut to the linear part 56 again, and rotation will be controlled.

  In the traveling toy 10 configured as described above, when a switch (not shown) provided in the toy main body 1 is turned on, the motor M rotates and the driving wheel 7 rotates. When the traveling toy 10 is not in contact with the ground, that is, when the weight of the driving wheel 7 supported by the rotating body 5 does not act, the elastic member 12 comes into contact with the straight portion 56 of the cam mechanism 51 and the elastic member 12 is attached. The rotation of the rotating body 5 is restricted by the force, and only the driving wheel 7 is rotationally driven without rotating the rotating body 5. Therefore, the operation sound due to the rotation of the rotating body 5 is not generated, and the possibility of winding a string or the like is further reduced.

  Further, when the traveling toy 10 is grounded, the rotating body 5 is not rotated by the own weight of the traveling toy 10 and the urging force of the elastic member 12 contacting the linear portion 56 of the cam mechanism 51, and only the driving wheel 7 is rotated and moved forward. . At this time, since the rotation of the rotating body 5 is restricted not only by the weight of the traveling toy 10 but also by the biasing force of the elastic member 12, the straight traveling performance is improved as compared with the conventional traveling toy. As a result, when a course with side walls on the left and right is run, even if the toy main body 1 comes into contact with the side walls, the rotation of the rotating body 5 is restricted, and the traveling toy 10 moves forward on the course. Thereby, traveling on a course that could not be done with a conventional traveling toy is realized, and the range of play can be expanded.

  Furthermore, a slightly protruding rail is arranged at the center in the width direction of the course, and the traveling toy 10 is placed on the rail so that the rail is positioned between the pair of driving wheels 7, so that the traveling toy 10 travels on the course while being guided by the rail. You can also In the conventional traveling toy, since the rotating body 105 rotates when the traveling toy is lifted, the traveling toy cannot be arranged so that the rail is positioned between the drive wheels 107, and the rotating body 105 is fixed with a finger or the like. Even if it is arranged on the course, if the rail is bent on the opposite side of the rotating direction of the rotating body 105, the rotating body 105 rotates so as to sandwich the rail between the drive wheels 107 due to contact with the rail. The brake is applied. Therefore, in the conventional traveling toy, the toy main body 101 does not bend the curve and the traveling on the course cannot be realized. However, according to the present embodiment, the traveling can be performed on the course having the rail. .

Next, a case where the traveling toy 10 is prevented from proceeding by an obstacle will be described with reference to FIGS. 6 and 7. In the figure, the white arrow indicates the traveling direction of the traveling toy 10, and the solid line or dotted line arrow indicates the rotational direction of the rotating body.
First, as shown in FIG. 6A, when the traveling toy 10 is traveling straight, a force acts on the rotating body 5 in the counterclockwise direction indicated by the arrow. The rotating body 5 is stopped by the weight and the urging force of the elastic member 12 in contact with the straight portion 56 of the cam mechanism 51, and only the driving wheel 7 is rotating. Then, as shown in FIG. 6B, when it collides with the wall surface W, the drive wheel 7 tries to continue to rotate but is restricted by the frictional resistance with the floor, and the rotational force of the rotating body 5 is attached to the elastic member 12. Overcoming the force, the rotating body 5 rotates counterclockwise, and the toy body 1 also starts to rotate so as to avoid the wall surface W (FIG. 6C).

  At this time, the cam mechanism 51 integrally formed with the rotating body 5 also rotates, and the rotating body 5 is compared until the front end portion 57a of the cam mechanism 51 faces rearward (state of FIG. 7A) as described above. Rotate instantly. During this time, the state shown in FIG. 6B where the linear portion 56 is in contact with the elastic member 12 is changed to the state shown in FIG. 6C where the linear portion 56 side of the rear end portion 57c is in contact with the elastic member 12. At this time, the drive wheel 7 faces diagonally backward. When the cam mechanism 51 further rotates, the state shown in FIG. 6D is brought into contact with the elastic member 12 from the state shown in FIG. At this time, the drive wheel 7 further turns diagonally backward. Therefore, since the drive wheel 7 continues to rotate during the period from FIG. 6B to FIG. 7A, the toy body 1 moves away from the wall surface W obliquely rearward.

  Then, as shown in FIG. 7A, when the loosely bent portion 57b comes into contact with the elastic member 12, the elastic member 12 weakens the rotation of the rotating body 5 by the biasing force, that is, slowly rotates in time. Acts as follows. At this time, since the drive wheel 7 faces rearward with respect to the toy main body 1, the toy main body 1 further moves backward away from the wall surface W. Further, a time difference is generated by the urging force of the elastic member 12 until the cam mechanism 51 rotates and immediately before the front end portion 57a shown in FIG. At this time, since the drive wheel 7 faces obliquely forward, the toy body 1 moves so as to slightly approach the wall surface W. And when the front-end | tip part 57a gets over the elastic member 12, it will return to the stable state because the linear part 56 contact | abuts to the elastic member 12 again (FIG.7 (c)). When the straight portion 56 comes into contact with the elastic member 12 and returns to a stable state, the rotating body 5 stops due to the weight of the traveling toy 10 and the biasing force of the elastic member 12 that comes into contact with the straight portion 56 of the cam mechanism 51. By this series of operations, as shown in FIG. 7C, the direction of the drive wheel 7 changes and the direction in which the toy body 1 advances changes.

6 and 7, the case where the elastic force of the elastic member 12 is relatively strong has been described as an example. However, the movement of the traveling toy 10 can be changed by adjusting the elastic force of the elastic member 12.
For example, when the urging force of the elastic member 12 is weakened, the process from FIG. 6C to FIG. 7C is also performed instantaneously. Therefore, in this case, when the progress is blocked by the obstacle, the travel direction by the driving wheel 7 is changed by turning through the movement trajectory almost the same as that of the conventional traveling toy, and the vehicle moves forward in the direction not blocked.

  Next, if the urging force of the elastic member 12 is slightly stronger than the previous state and weaker than the above-described embodiment, the process from FIG. 6C to FIG. 7B is also performed relatively instantaneously. However, when the state shown in FIG. 7B is reached, the distal end portion 57a having a long distance from the rotation center O contacts the elastic member 12, so that the urging force of the elastic member 12 acts greatly, and the distal end portion 57a is elastic. While moving over the member 12, the rotation of the rotating body 5 is weakened, i.e., it rotates slowly in time. Then, the drive wheel 7 rotates in a short period of time, while moving slightly in the lateral direction or stopping for a moment and changing its direction again, that is, a state where the linear portion 56 is in contact with the elastic member 12. Return to. Accordingly, while moving differently from the previous two cases, the traveling direction of the drive wheel 7 is changed by turning, and the vehicle moves forward in an unobstructed direction.

  As described above, the traveling toy 10 of the present embodiment moves differently according to the time difference during one rotation of the cam mechanism 51 when the traveling toy 10 is blocked by an obstacle. The stronger the urging force of the elastic member 12, the longer the time that the cam mechanism 51 (rotating body 5) rotates once, and the driving wheel 7 rotates during that time, so that the traveling toy 10 seems to stop for a moment, It rotates while turning the rudder in a different direction, or moves differently from mechanical movement.

  The urging force of the elastic member 12 can be adjusted by changing the distance between the fulcrum 11 and the force point of the cam mechanism 51 in addition to changing the strength of the elastic member 12. Furthermore, the distance between the fulcrum 11 and the force point of the cam mechanism 51 is preferably variable. For example, by making it possible to easily adjust the position of the fulcrum 11 in a stepwise manner, it becomes easy to adjust the urging force at the time of manufacture. In addition, the movement of the traveling toy 10 can be adjusted by the user by allowing the user to adjust the movement himself / herself.

  Further, the traveling toy 10 includes the strength of the motor M, the traveling speed at the time of the collision, the direction of the collision, the strength of the collision, the weight of the toy body 1, the frictional force between the elastic member 12 and the cam mechanism 51, the driving wheel. It moves differently depending on various conditions such as frictional force between 7 and the floor.

  As a modification, for example, a cam mechanism 51A as shown in FIG. 8 can be used. The cam mechanism 51A includes straight portions 56a and 56b extending in parallel with the center line P at positions offset from the centers O on both sides in the width direction, and arc portions 58a and 58b having the same curvature in the front and rear connecting the straight portions 56a and 56b. The rotating body 5 rotates and the elastic member 12 is configured not to be stable even when it comes into contact with the arc portions 58a and 58b other than the straight portions 56a and 56b.

  In this cam mechanism 51A, when the rotating body 5 tries to rotate slightly, the urging force of the elastic member 12 that contacts the linear portion 56a of the cam mechanism 51 surpasses the rotating force of the rotating body 5 and its rotation is restricted (FIG. 8). (A)). Further, when a relatively large rotational force acts on the rotating body 5 and the rotational force exceeds the urging force of the elastic member 12, the rotating body 5 rotates counterclockwise and the arc portion 58 b is in contact with the elastic member 12. The cam mechanism 51A starts to rotate. And it returns to the stable state by the linear part 56b contact | abutting to the elastic member 12, and the rotary body 5 stops (FIG.8 (b)). At this time, the rotator 5 rotates 180 ° and the drive wheel 7 faces rearward, so that the toy body 1 changes its direction slightly and moves backward.

  Also, when the toy body 1 is moving backward, if the rotating body 5 tries to rotate slightly, the biasing force of the elastic member 12 that comes into contact with the straight portion 56b of the cam mechanism 51 overcomes the rotating force of the rotating body 5 and rotates. Is regulated (FIG. 8B). Further, when a relatively large rotational force acts on the rotating body 5 and the rotational force exceeds the urging force of the elastic member 12, the rotating body 5 rotates counterclockwise and the arc portion 58 a is in contact with the elastic member 12. The cam mechanism 51A starts to rotate. Then, the linear portion 56a comes into contact with the elastic member 12 to return to a stable state, and the rotating body 5 stops (FIG. 8A). At this time, the rotator 5 further rotates 180 °, and the drive wheel 7 faces forward, so that the toy body 1 slightly changes its direction and moves forward again.

  Therefore, in the traveling toy 10 including the cam mechanism 51A of the present modified example, so-called switchback traveling is performed in which the vehicle travels backward at the time of collision when traveling forward and moves forward at the time of collision when traveling backward. it can. As described above, various movements can be realized by changing the shape of the cam mechanism, and not only the cam mechanisms 51 and 51A but also a cam mechanism having an arbitrary shape can be used.

As another modification, for example, a coil spring as shown in FIG. 9 may be used.
In FIG. 9A, the elastic member 12 </ b> A made of a coil spring is applied in a manner in which a compressive force acts on both sides in the front-rear direction of the bar-like or plate-like pressing member 13 that abuts on the straight portion 56 of the cam mechanism 51 and extends in parallel. Is provided. Further, in FIG. 9B, the elastic member 12B made of a coil spring in such a manner that a pressing force acts on both sides in the front-rear direction of the bar-shaped or plate-shaped pressing member 13 that abuts on the straight portion 56 of the cam mechanism 51 and extends in parallel. Is provided. In addition, although illustration is abbreviate | omitted, you may use combining both elastic member 12A, 12B. In the above embodiment, the elastic member 12 directly acts on the cam mechanism 51. However, in this modification, the elastic members 12A and 12B are indirectly applied to the cam mechanism 51 via the pressing member 13 in other words. It is working.

  As described above, according to the traveling toy 10 of the present embodiment, the elastic member 12 as the rotation restricting means acts on the cam mechanism 51 of the rotating body 5 and restricts the rotation of the rotating body 5. Even if it is lifted, the rotation of the rotating body 5 is restricted. Thereby, generation | occurrence | production of the operation | movement sound by the rotation of the rotary body 5 and the entrainment of a string etc. can be prevented. Even if the driving wheel 7 of the toy body 1 is grounded, the rotation of the rotating body is regulated by the elastic member 12 in addition to the weight of the traveling toy 10 unless the obstacle is blocked by the obstacle. The straightness of the toy 10 is improved. As a result, even if the course with side walls on the left and right or running on the rail is run, the running toy 10 does not rotate by simply touching the side wall or rail, so the running toy 10 can run and play on the course. . Furthermore, since the elastic member 12 acts on the cam mechanism 51 provided on the rotating body 5, the movement of the traveling toy 10 is controlled by the shape of the cam mechanism 51 when the advancement is blocked by an obstacle (when a collision occurs). The movement of the traveling toy 10 can be changed by changing the shape of the cam mechanism 51. Thereby, if the several traveling toy 10 from which a cam shape differs is run simultaneously, the traveling toy 10 of various traveling patterns can be seen.

  In addition, various applications are possible by improving the straightness of the traveling toy 10. For example, by decentering the idle wheel 6, it can be moved forward while swinging up and down. In addition, as a method of decentering the idle wheel 6, it is possible to make the shape of the idle wheel 6 itself an ellipse or to shift the connecting portion with the axle. Thereby, for example, the traveling toy 10 shown in FIG. 1 can be caused to travel as if it is walking with its buttocks.

  In other words, according to the present embodiment, the combination of the elastic member 12 and the cam mechanism 51 maintains a balance between the straight traveling performance and the rotational performance at the time of the mystery traveling, and thereby the traveling toy 10 having the mystery traveling function. The range of play can be expanded.

  Further, according to the present embodiment, the cam mechanism 51 is provided with the linear portion 56 that extends along the traveling direction of the toy body 1 and contacts the elastic member 12, so that the straightness can be further improved. it can. Instead of providing the straight portion 56, a region having a large frictional resistance may be provided on the outer peripheral edge of the cam mechanism 51. Also by this, the elastic member 12 restricts the rotation of the rotating body 5 in this region, so that the straight traveling performance of the traveling toy 10 can be improved.

  In addition, according to the present embodiment, the rotation restricting means is configured by the elastic member 12 that applies a biasing force to the rotating body 5 and restricts the rotation of the rotating body 5, so that the rotating body 5 can be rotated with a simple configuration. Can be regulated. Further, the movement of the traveling toy 10 can be changed by adjusting the urging force according to the shape, thickness, strength, fulcrum position, and the like of the elastic member 12. Further, by making the position of the fulcrum variable, the urging force of the elastic member 12 can be adjusted, and the balance between the straight traveling performance and the mystery traveling performance can be adjusted.

  In this embodiment, the rotating shaft 42 to which the bevel gear 43 and the crown gear 44 are attached, the rotating body 5 that is inserted through the rotating shaft 42, and the axle 45 that is supported by the rotating body 5 and that has the gear 46. It is preferable that the drive wheel 7 is unitized and configured to be detachable from the toy body 1. Thereby, the movement of the traveling toy 10 can be changed simply by replacing the unit with a different cam mechanism.

In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
In particular, in the above embodiment, the rotator 5 having the cam mechanism 51 is illustrated, but it is not always necessary to have the cam mechanism, and the elastic member 12 acts on the rotator 5 to restrict the rotation of the rotator 5. May be. Even in this case, even when the toy body 1 is lifted, the rotation of the rotating body 5 is restricted, and it is possible to prevent the generation of an operating sound and the entanglement of the string or the like due to the rotation of the rotating body 5. Even when the driving wheel 7 is grounded, the rotation of the rotating body 5 is restricted by the urging force of the elastic member 12 in addition to the weight of the traveling toy 10 unless the obstacle is blocked by the obstacle. The straightness of the toy 10 is improved. As a result, even when the vehicle has a side wall on the left and right or runs on a course provided with rails, the traveling toy 10 does not rotate just by touching the side wall or rail, so the traveling toy 10 can be run and played on the course. Note that it is preferable in terms of straightness that the frictional force of the portion of the rotating body 5 on which the elastic member 12 acts during forward travel is larger than that of the other portions. Furthermore, since the elastic member 12 acts on the rotating body 5 without using a gear mechanism, the number of parts can be reduced, and the manufacturing cost can be reduced by simplifying the structure.

  Further, the power transmission mechanism 4 can adopt any configuration, and the rotary shaft 42 and the output shaft of the motor M can be arranged coaxially or in parallel, or the motor output shaft can be rotated as it is. It may be used as the shaft 42. The gear is not limited to a bevel gear or the like, and a known gear such as a worm gear can be applied.

  In the embodiment described above, a pair of drive wheels 7 are provided symmetrically with respect to the traveling direction, but the present invention is not limited to this, and as shown in FIGS. The drive wheel 7 may be provided only on the forward rotation side, and the protrusion 8 may be provided on the opposite side. The protrusions 8 need only be formed to such an extent that they do not become extreme resistance, and the shape and the like can be arbitrarily selected. If this one-side wheel is applied to a conventional traveling toy, the rotation of the rotating body 105 is prioritized due to variations in the ground resistance between the driving wheel and the protrusion, and the straightness is reduced. In the present invention, the biasing force of the elastic member 12 is reduced. Thus, the rotation of the rotating body 5 is regulated to some extent, so that even if it is a one-side wheel, straightness is ensured and traveling is possible.
