Description

  The present invention relates to a traveling toy that jumps.

  Conventionally, as a jumping mechanism for a traveling toy that jumps, the front wheel shaft is supported by an arm having the rear portion of the traveling toy as a fulcrum, and the rear wheel shaft is supported by an arm having the front portion of the traveling toy as a fulcrum. A mechanism that allows the character to expand downward and jump, or a mechanism that causes the front wheel arm and rear wheel arm to be pushed downward from the fulcrum near the center of the traveling toy to jump downward, or the wheel axle does not move and moves inside the traveling toy. There was a mechanism for jumping a traveling toy by suddenly moving a heavy object upward.

  Regardless of the jumping mechanism, compressing or deflecting elastic members such as coil springs and beard (gull) springs to store the restoring force of the springs, releasing the springs all at once, and pressing the ground suddenly Or a heavy object is suddenly raised above the traveling toy and the traveling toy jumps into the air.

  However, the elastic member used for the jumping mechanism is in an extended state after jumping, the wheel attached to the jumping mechanism is positioned below the vehicle body, the center of gravity at the time of landing is raised, and the landing after the jumping Due to the impact, the power that is compressed or deflected again and the elastic member restores again causes the traveling toy after landing to rebound. Therefore, it has been a cause of an unstable posture leading to the fall of the traveling toy.

  In addition, rubber materials and elastomer materials used as tire materials are similarly compressed by the impact of landing on the traveling toy, and the restoring power causes the traveling toy after landing to rebound, resulting in an unstable posture that leads to falling. Cause.

For example, as disclosed in Japanese Utility Model Publication No. 47-35908, “jumping car toy”, an arm that supports a front wheel shaft with a fulcrum near the center of the traveling toy and an arm that supports a rear wheel shaft with a fulcrum near the center are provided. There is a traveling toy in which both arms are pushed downward by a leaf spring to jump. Even this traveling toy has a high center of gravity at the time of landing, and the leaf spring is recompressed by contact with the road surface and rebounds.
Japanese Utility Model Publication No. 47-35908

  The toy that moves the above-mentioned heavy object suddenly has been difficult to jump high. In addition, using the method of pushing down the arm that pivots the wheel downward, the toy can be jumped higher, but the elastic member for jumping is re-compressed or bent due to the impact at the time of landing. However, this may cause the posture of the traveling toy to collapse.

And this traveling toy has to have an unstable landing with a high center of gravity when landing. For this reason, it was still difficult to jump high.
Therefore, even when the traveling toy jumps high, the elastic member for jumping is compressed or deflected again by the impact of landing, so that the traveling toy after landing does not rebound, There is a need for a traveling toy that jumps high, can maintain a normal posture when landing, and does not fall over after landing.

Therefore, the present invention has been made in view of the above-described problems of the prior art, and makes the running toy jump higher and not rebound violently even when jumping high, so that a normal posture is achieved.

  The hook-shaped end portion formed in the engagement hook 28 is hooked between the engagement hole 20 formed in the lock lever 18 and the hook-shaped end portion when the lock lever 18 is depressed. Further, the elastic member engaging projection 30 and a cam gear 70 described later are connected by a third elastic member 78 serving as a tension spring, and a direction in which the engagement state between the engagement hook 28 and the lock lever 18 is maintained. In addition, the restoring force of the third elastic member 78 is applied.

  Further, the sliding of the sliding body 60, which will be described later, is pressed in a direction to release the hooked state of the engagement hook 28 and the lock lever 18, and the lock lever 18 is released from the hooked state.

  Next, the legs will be described with reference to FIGS. 2, 3, 5, and 7 (B). The leg portion includes a first leg member 36 that pivotally supports the front wheel 44 and a second leg member 46 that pivotally supports the rear wheel 54, and is formed in a hole formed in the center of both leg members. A leg shaft 34 is pivotally supported to form an X-shaped leg portion. The leg portion can be expanded and contracted by the displacement of the X-shape.

  The first leg member 36 is formed by a plate that arranges two substantially rectangular plates in parallel and connects the plates. Further, shaft holes for pivotally supporting the front wheel 44 are formed on both side surfaces in the vicinity of one end portion, and a front wheel shaft 40 that pivotally mounts the front wheel 44 is pivotally supported. Further, shaft holes are formed on both side surfaces near the other end, and are pivotally supported by a first support shaft 38 that is pivotally mounted on the rear rear side of the chassis 12.

Further, shaft holes that are pivotally supported together with the second leg member 46 are formed on both side surfaces of the center of the first leg member 36. A traveling gear 42 is attached to the front wheel shaft 40. In addition, wheels serving as front wheels 44 are attached to both ends of the front wheel shaft 40.
The second leg member 46 is formed of two substantially rectangular plates arranged in parallel in the same manner as the first leg member 36 and connecting between the plates. Further, the second leg member 46 is formed larger than the first leg member 36 and is positioned outside the first leg member 36.

  Further, on both side surfaces in the vicinity of one end portion, a long hole 59 that pivotally supports the rear wheel 54 is formed, and a rear wheel shaft 50 that pivotally mounts the rear wheel 54 is suspended. Further, shaft holes are formed on both side surfaces near the other end, and the second support shaft 48 pivoted so as to be slidable between the long holes formed on both side surfaces in front of the chassis 12 is rotated. It is supported freely. Further, shaft holes that are pivotally supported together with the first leg member 36 are formed on both side surfaces of the center of the second leg member 46. Further, the rear wheel shaft 50 has a worm gear 52 attached thereto, and wheels serving as the rear wheels 54 are attached to both ends of the rear wheel shaft 50.

  And the engaging part 56 formed in the convex shape is provided in the edge part by the side of the wheel of the 2nd leg member 46. As shown in FIG. Further, sliding body pressing portions 58 that are in contact with the sliding body 60 are formed on the inner side of both end surfaces of the second leg member 46 on the chassis 12 side. In the embodiment, the sliding body pressing portion 58 is formed in a columnar shape.

  Next, the sliding body 60 will be described with reference to FIGS. 4, 5, and 7 (B). The sliding body 60 is formed in a thin plate shape formed in a square shape, and an opening through which the flywheel portion passes is formed in the center portion. Further, on the lower surface of the sliding body 60, two engaging convex portions 62, which are convex portions formed in a plate shape pressed by a cylindrical sliding body pressing portion 58 formed on the leg portion, are formed. Further, the end of the sliding body 60 is in contact with the engagement hook 28.

  The sliding body 60 is located in the vicinity of the center of the rear surface of the chassis 12 and slides in the front-rear direction of the chassis 12 by pressing by the sliding body pressing portion 58 formed on the leg portion and the engagement hook 28. . Specifically, sliding of the sliding body 60 from the front to the back is performed by pressing from the sliding body pressing portion 58 of the second leg member 46. Further, the sliding from the rear to the front is performed by being pressed by the action of the third elastic member 78 engaged with the engagement hook 28. When the sliding body 60 slides, the end of the sliding body 60 presses the engagement hook 28 and rotates around the engagement hook shaft 32, and the engagement between the lock lever 18 and the engagement hook 28 is performed. The state is released.

  Next, a flywheel part is demonstrated using FIG.2 and FIG.4 and FIG.6. The flywheel part is composed of a flywheel 66 and an intermediate gear 68 and is located on the front side of the traveling toy 10. The flywheel 66 is formed of a metal material in a thick disc shape, and is rotatably supported by two parallel strips formed on the back surface of the chassis 12.

  Further, a pinion gear (not shown) that meshes with the intermediate gear 68 is axially attached to a shaft (not shown) that is pivotally attached to the protrusion and rotatably mounted on the protrusion. An intermediate gear 68 that meshes with the pinion gear is rotatably supported on the two parallel protrusions on which the flywheel 66 is axially supported, slightly forward of the flywheel 66. The intermediate gear 68 is a gear in which two spur gears are overlapped. One spur gear meshes with the pinion gear of the flywheel 66, and the other spur gear is the first when the leg is retracted. It meshes with a traveling gear 42 that is pivotally supported by the leg member 14.

  When the leg portion of the traveling toy 10 is retracted, the traveling gear 42 and the intermediate gear 68 mesh with each other, and the traveling gear 42 that is coaxial with the front wheel 44 rotates with the rotation of the front wheel 44. The force is transmitted through the intermediate gear 68 and rotates the flywheel 66. When the flywheel 66 rotates, the rotation is sustained by the inertial force of the flywheel 66 and becomes the driving force of the traveling toy 10.

  Next, the jump start mechanism will be described with reference to FIGS. 2 to 4 and FIG. The jump start mechanism includes an L-shaped joint 82 and a gear 70 with a cam. The cam geared gear 70 has a spur gear 74 formed on one of its shafts, and a cam 72 whose height is displaced inwardly on the other shaft. When the lock lever 18 is in the depressed state, the cam 72 of the cam gear 70 and the convex portion 85 of the L-shaped joint 82 are in contact with each other. With the displacement of the height of the cam 72 with respect to the inner direction of the cam 72 due to the rotation of the cam-equipped gear 70, the abutting convex portion 85 is pressed against the cam 72, and the L-shaped joint 82 is centered on the joint support shaft 86. It is rotated.

  In the vicinity of the rear of the chassis 12, a gear shaft 76 with a cam that is axially fixed to the upper surface of the chassis 12 is formed, and the tip of the gear shaft 76 with a cam is formed in a rivet shape. The cam gear 70 is pivotally supported so as to be slidable and rotatable in the vertical direction with respect to the cam gear shaft 76. The cam-equipped gear 70 includes a fourth elastic member 80 serving as a compression spring. One of the fourth elastic members 80 abuts on a rivet at the tip of the cam-equipped gear shaft 76 and the other is cam-attached. It contacts in the gear 70. The fourth elastic member 80 presses the cam gear 70 so as to always slide upward. The cam-equipped gear 70 is pressed so as to slide downward by the convex portion 22 formed on the lock lever 18 when the lock lever 18 is pushed down to be in the depressed state.

  Further, a protrusion is formed at a position slightly away from the center of the shaft of the end face of the spur gear 74 of the cam gear 70. The third elastic member 78 serving as a tension spring connects the elastic member engaging protrusion 30 formed with the engaging hook 28 to the protrusion, and the third elastic member 78 expands as the gear 70 with the cam rotates. Is done. When the engagement between the spur gear 74 of the cam gear 70 and the worm gear 52 is released, the cam gear 70 returns to the original rotational position by the restoring force of the third elastic member 78. The restoring force of the third elastic member 78 is used for two of the return of the engagement hook 28 and the return of the rotation of the gear 70 with the cam.

  The state where the spur gear 74 of the cam gear 70 and the worm gear 52 are engaged is engaged when the three states are satisfied. One of the states is that the lock lever 18 is depressed. As another state, the rear wheel shaft 50 is positioned above the elongated hole 59 formed in the second leg member 46 by, for example, grounding the traveling toy 10 on the road surface. As another state, the legs are degenerated. That is, the state where the spur gear 74 of the cam gear 70 and the worm gear 52 are not engaged does not mesh when any one of the three states described above is not satisfied.

  Further, when the cam 72 of the cam gear 70 is in contact with the convex portion 85 of the L-shaped joint 82, the lock lever 18 is depressed, and the convex portion 22 formed on the lock lever 18 moves the cam gear 70 downward. When it is slid, it is in a contact state, and when the lock lever 18 is released, it does not contact.

  Next, the L-shaped joint 82 is pivotally supported by a joint support shaft 86 pivoted behind the chassis 12 so as to be freely rotatable. One end of the L-shaped joint 82 is formed in a bowl shape, and a convex portion 85 that contacts the cam 72 of the cam-equipped gear 70 is formed at the other end. The flange 84 formed on one side of the L-shaped joint 82 engages with the engaging portion 56 of the second leg member 46 when the leg portion is retracted. Thereafter, the L-shaped joint 82 is disengaged from the engaging portion 56 of the leg when the cam geared wheel 70 rotates approximately half a turn. That is, when the rear wheel 54 of the traveling toy 10 rotates, the gear 70 with the cam rotates slowly via the worm gear 52, and the engagement state with the leg portion is released when the gear 70 with the cam rotates approximately half a half. Thus, the traveling toy 10 jumps.

  A fifth elastic member 88 serving as a tension spring is provided to connect the vicinity of the flange 84 of the L-shaped joint 82 and a rod 81 (see FIG. 2) formed perpendicular to the rear surface of the chassis 12, and the L-shaped joint. A restoring force is applied in a direction in which the contact state between the collar 84 of the 82 and the engaging portion 56 of the leg is maintained. Further, by changing the diameter of the spur gear 74 of the cam-equipped gear 70, it is possible to change the distance until the traveling toy 10 jumps.

  Next, an operation example of the jump start mechanism of the traveling toy 10 will be described with reference to FIGS. FIG. 6A shows a state in which the pressed state of the lock lever 18 is released, and the leg portion is in a retracted state. Further, since the leg portion is in the retracted state, the traveling gear 42 and the intermediate gear 68 are in meshed state. The cam gear 70 is located above, and the worm gear 52 is not meshed.

  The transition from FIG. 6A to FIG. 6B will be described. When the end of the lock lever 18 is pressed, the lock lever 18 rotates about the lock lever support shaft 24, and the lock lever 18 engages with the engagement hook 28 and enters the pressed state. By pressing the lock lever 18, the cam-equipped gear 70 is pressed by the convex portion 22 formed on the lock lever 18, slides below the cam-equipped gear shaft 76, and meshes with the worm gear 52. .

  When the lock lever 18 is depressed, the first elastic member 14 in contact with the leg portion and the lock lever 18 is pressed by the lock lever 18 and is compressed.

  In the state of the traveling toy 10 shown in FIG. 6B, when the traveling toy 10 is grounded on the road surface and the user presses the traveling toy 10 in the forward direction and rotates the front wheel 44, the front wheel shaft 40 is pivotally supported. The traveling gear 42 thus rotated rotates, and the rotation is transmitted to the flywheel 66 through the intermediate gear 68 in mesh with the traveling gear 42 to rotate the flywheel 66. Due to the effect of the rotation of the flywheel 66, the front wheel 44 rotates for a long time.

  Further, when the traveling toy 10 is lifted in the state of the traveling toy 10 shown in FIG. 6B, the rear wheel shaft 50 that pivotally mounts the rear wheel 54 loosely inserted into the elongated hole 59 formed in the second leg member 46. Falls downward due to its own weight. As a result, the meshed state of the spur gear 74 of the cam-equipped gear 70 and the worm gear 52 is released, and the cam-equipped gear 70 that is disengaged from the worm gear 52 is engaged with the cam-equipped gear 70. The cam gear 70 is returned to the original rotational position by the action of the restoring force of the member 78.

  Accordingly, even when the traveling toy 10 is grounded on the road surface and pressed forward in order to rotate the flywheel 66 at a high speed, the cam gear 70 returns to the original position each time the traveling toy 10 is lifted. Therefore, the traveling toy 10 always allows a jump start mechanism to operate after traveling a certain distance, thereby enabling jumping.

  Similarly, when the traveling toy 10 before jumping is lifted during traveling, the engagement between the spur gear 74 of the gear 70 with the cam and the worm gear 52 is released when the rear wheel 54 is separated from the road surface, and the cam The attached gear 70 returns to the original rotational position. That is, even if the traveling toy 10 is lifted during traveling and the rear wheel 54 is rotating, the jump start mechanism does not operate.

  A transition from FIG. 6B to FIG. 7A will be described. When the flywheel 66 is rotated at a high speed, the front wheel 44 is maintained in a rotated state by the inertial force of the flywheel 66. In this state, when the traveling toy 10 is grounded on the road surface, the traveling toy 10 enters the traveling state by the driving force generated by the rotation of the front wheels 44. Thereafter, when the traveling toy 10 enters the traveling state, the rear wheel 54 is also rotated by the frictional force with the road surface. Due to the rotation of the rear wheel 54, the cam gear 70 rotates through the worm gear 52 that is coaxial with the rear wheel 54. In addition, the cam 72 rotates as the cam gear 70 rotates. The cam-equipped gear 70 makes a substantially half rotation, whereby the convex portion 85 of the L-shaped joint 82 is pressed by the cam 72. When the convex portion 85 is pressed, the L-shaped joint 82 rotates about the joint support shaft 86, and the hook 84 formed at the tip of the L-shaped joint 82 engages with the engaging portion 56 of the leg portion. The state is released.

  Next, the transition from FIG. 7A to FIG. 7B will be described. When the engagement between the engaging portion 56 of the leg portion and the L-shaped joint 82 is released, the leg portion is extended by the restoring force of the first elastic member 14. As a result, the meshing between the cam gear 70 and the worm gear 52 and the meshing between the traveling gear 42 and the intermediate gear 68 are released. Further, when the leg portion extends, the front wheel 44 moves slightly rearward of the traveling toy 10. Further, the meshing between the cam gear 70 and the worm gear 52 is released, and the cam gear 70 returns to the original rotational position, whereby the jump start mechanism returns to the initial state.

  Next, the transition from FIG. 7B to FIG. 8A will be described. The transition from FIG. 7B to FIG. 8A is instantaneous. The traveling toy 10 jumps by the front wheel 44 and the rear wheel 54 violently pressing the ground by the restoring force of the first elastic member 14. At this time, due to the extension of the leg portion, the sliding body 60 that comes into contact with the sliding body pressing portion 58 formed on the second leg member 46 that pivotally supports the rear wheel 54 of the traveling toy 10 moves to the rear of the chassis 12. Slide and press the engagement hook 28. When the engagement hook 28 is pressed, it rotates about the engagement hook shaft 32, and the engagement state with the lock lever 18 is released. The lock lever 18 is pushed up by the second elastic member 26 that contacts the chassis 12 and the back surface of the lock lever 18. Further, when the lock lever 18 is released, the cam-equipped gear 70 slides upward by the restoring force of the fourth elastic member 80 and moves backward.

  Next, the transition from FIG. 8A to FIG. 8B will be described. The traveling toy 10 jumps by pressing the road surface by the extension of the legs. And if a leg part extends rapidly, a leg part will return to the chassis 12 side by the reaction. As a result, when the leg portion is retracted to the return position, the flange 84 of the L-shaped joint 82 and the engaging portion 56 of the leg portion are engaged and held in the retracted state.

  Due to the contraction of the leg portion, the traveling gear 42 and the intermediate gear 68 are brought into the meshing state again, and the rotation from the flywheel 66 is transmitted to the front wheel 44. Further, in this state, the first elastic member 14 that contacts the leg portion and the lock lever 18 is supported in a released state in which no pressure is applied from each member. Since the leg portion is retracted and stored in this way, it can jump higher than the conventional jumping toy.

  Since the lock lever 18 is released, the engagement between the worm gear 52 and the gear 70 with the cam is maintained in the released state.

  FIG. 9 shows a state of the traveling toy 10 traveling on the road surface at and after landing. Since the outer peripheral surfaces of the front wheel 44 and the rear wheel 54 of the traveling toy 10 have a low repulsion structure formed of low repulsion rubber as a low repulsion material, the impact at the time of landing is absorbed by the low repulsion member. Further, since the first elastic members 14 that are in contact with the leg portions and the lock lever 18 are supported in a released state in which no pressure is applied from the respective members, the first elastic members 14 are re-engaged by the impact at the time of landing. There is no compression. Accordingly, the traveling toy 10 can continue traveling while maintaining the state of FIG. 9 without rebounding.

By configuring as described above, to provide a traveling toy that makes a beautiful landing that keeps a normal posture without causing a rebound violently even when the traveling toy jumps higher and jumps higher. Can do.
In addition, in order to make a vehicle body jump horizontally and to make it land reliably from a wheel, according to the shape and weight of the chassis 12 or a wheel, a metal weight may be attached to the chassis 12, and a gravity center position may be adjusted.

  In the above-described embodiment, the flywheel 66 jumps high so that the vehicle travels reliably after landing. However, the flywheel 66 is omitted, and the travel toy 10 is pushed by hand and travels. If you travel a distance, you can enjoy jumping high.

  Further, in the above-described embodiment, although the wheels of the low resilience structure are formed by covering the outer periphery of the front wheels 44 and the rear wheels 54 with the low resilience rubber, the shape of the tire is formed together with the rim of the wheels by the synthetic resin, and the normal rubber material May be formed thinly and covered with a synthetic resin wheel to form a low repulsion structure in which the repulsive force of the rubber material is reduced.

The traveling toy 10 is not limited to a normal passenger car type, but may be an automobile such as an off-road type having large wheels.
Further, as another embodiment, a difference can be provided in the left and right weight balance in the wheel 12 and the chassis 12 of the traveling toy, and the landing can be made by making one turn in the horizontal direction when jumping.

  As shown in FIG. 10, the second embodiment rotated in the lateral direction includes a front wheel 44 and a rear wheel 54 having a large tire diameter so as to be an off-road type, and has a hollow cylindrical shape attached to the front wheel shaft 40. A plate-like circular front wheel hub 45 is spread from the outer periphery of the wheel portion to the outer periphery, and a thin rubber material with a tire shape is fixed by the front wheel hub 45 to make the front wheel 44 resemble an off-road tire, and the rear wheel 54 is also Similarly, a plate-shaped circular rear wheel hub 55 is formed on the outer periphery of the hollow cylindrical wheel portion, and a tire-shaped rubber material is attached.

  As described above, since a plate-shaped hub is provided on the outer periphery of the hollow wheel portion and a thin rubber material is attached to form a tire shape, the wheel is formed to be extremely larger than a normal wheel with respect to the vehicle body. However, when the front wheel 44 and the rear wheel 54 are pulled up so as to be housed in the chassis 12 after the chassis 12 and the like are flipped upward by the first elastic member 14, the jumping force of the chassis 12 and the like can be reduced. Is reduced, and the traveling toy 10 can be jumped high.

  Incidentally, the front wheel 44 and the rear wheel 54 are not only used for forming a hub on the outer periphery of the hollow wheel portion to make the front wheel 44 and the rear wheel 54 light in weight and having extremely small elastic force but also having a large diameter by a synthetic resin. It may be formed into a hollow wheel part or a hollow tire shape, and a rubber layer may be applied or pasted to form a front tire 44 or a rear wheel 54 having a rubber tire shape and a small repulsive force.

  In the embodiment shown in FIG. 10, a spur gear is used as the engaging gear 53 instead of the worm gear 52 as a jump start mechanism, and this engaging gear 53 is attached to the rear wheel shaft 50. A reduction gear 73 and a gear plate 71 with a cam pin are attached to the rear lower side of the chassis 12.

  The cam pin-equipped gear plate 71 and the reduction gear 73 are rotatable with their rotational axes set in the horizontal direction. When the traveling toy 10 is placed on the floor or the like, the engagement gear 53 and the reduction gear 73 mesh with each other, and the traveling gear When the toy 10 is lifted, the rear wheel shaft 50 is slightly lowered by its own weight, and the engagement gear 53 and the reduction gear 73 are disengaged as in the above-described embodiment.

  Further, the gear plate 71 with the cam pin supports the rotation shaft so as to be slightly movable up and down, and when the lock lever 18 is pushed down to set it, the convex portion 22 provided on the lower surface of the lock lever 18 The tooth portion formed on the outer periphery of the gear plate 71 with the cam pin by being pushed down is engaged with the tooth portion of the reduction gear 73.

  Therefore, even when the lock lever 18 is not pushed down or when the traveling toy 10 is lifted and the rear wheel 54 is floated in the air even when the lock lever 18 is pushed down, the cam pin-equipped gear plate 71 has the reduction gear 73. When the reduction gear 73 and the engagement gear 53 are disengaged, the gear plate 71 with the cam pin is positioned by the third elastic member 78 at the rotational position with the cam pin as the initial position.

  Then, when the traveling toy 10 is driven in a state where the lock lever 18 is pushed down and the rear wheel 54 is grounded and the engagement gear 53 and the reduction gear 73 are engaged with each other, the traveling toy 10 is moved in accordance with the rotation of the rear wheel 54. The engagement gear 53 rotates, and the rotation of the engagement gear 53 is transmitted to the cam pin-equipped gear plate 71 via the reduction gear 73.

  Therefore, when the cam pin-equipped gear plate 71 is rotated by a predetermined angle by traveling of the traveling toy 10, the pin provided on the side surface of the cam pin-equipped gear plate 71 projects forward from the joint support shaft 86 of the L-shaped joint 82. The protrusion provided at the tip of the extension 83 is pushed down against the tension of the fifth elastic member 88 and the L-shaped joint 82 is rotated about the joint support shaft 86, whereby the flange 84 of the L-shaped joint 82 is rotated. And the engagement portion 56 of the rear wheel 54 can be disengaged.

  Further, on the both sides of the center of the chassis 12, a substantially inverted triangular protrusion 91 is formed protruding upward in the middle between the front wheel 44 and the rear wheel 54. One protrusion 91 is a balance weight made of metal such as lead alloy. The other is a dummy weight made of hollow resin.

In this way, by providing the metal protrusion 91 on one side of the chassis 12 as a balance weight that is a weight, by biasing the center of gravity of the left and right of the chassis 12 toward the balance weight that is the metal protrusion 91, When the traveling toy 10 is jumped, it is rotated in the lateral direction.
In addition, not only when only one side is made of the metal protrusion 91, metal protrusions 91 of different sizes are attached to the left and right, and the resin protrusion 91 is attached to the small metal protrusion 91. The appearance may be adjusted by covering.

  Then, the size of the metal protrusion 91, that is, the weight of the metal protrusion 91 is adjusted in accordance with the total weight of the traveling toy 10 and the weights of the front wheel 44 and the rear wheel 54. To make a correct landing on the front wheel 44 and the rear wheel 54.

  Further, in addition to forming the metal protrusion 91 on one side of the chassis 12, when the metal protrusion 91 is provided on the left side of the chassis 12, a disk-shaped metal is formed on the right front wheel 44 and the rear wheel 54. A weight such as a plate is attached so that the left and right weights of the front wheel 44 and the rear wheel 54 are different from each other, and the opposite front wheel 44 and the rear wheel 54 provided with the metal protrusion 91 on the chassis 12 may be made heavy. is there.

  Thus, by attaching a balance weight to the chassis 12 and decentering the center of gravity of the vehicle body from the center line in the front-rear direction of the chassis 12 to the right or left, the leg portion is extended by the first elastic member 14 to raise the vehicle body, When the legs are retracted and the wheels are pulled into the chassis 12, the rising inertia force of the chassis 12 collapses from side to side and rotates laterally.

  Further, even when the left and right wheel weights of the front wheel 44 and the rear wheel 54 are made different depending on the weight of a metal plate or the like, when the chassis 12 rises and the legs are retracted, the force received by the chassis 12 when the wheels are pulled up is increased. Different from the left and right, the rising inertia force of the chassis 12 collapses and rotates laterally.

  A balance weight as a weight is attached to the chassis 12, and the wheel on the opposite side of the balance weight is made heavy by a weight such as a metal plate. It is possible to land from the wheel by making one rotation in the direction.

  In addition, it is possible to cause lateral rotation at the time of jumping by incorporating a weight such as a metal disk on either the left or right of the front wheel 44 and the rear wheel 54 without attaching a balance weight or a dummy weight to the chassis 12. The weight of the traveling toy 10 as a whole and the front wheels, such as when weights are incorporated only into the wheels or when balance weights are attached only to the chassis 12, and when weights are incorporated into the wheels and balance weights are attached to the chassis 12 on the opposite side, etc. In accordance with the weight balance of the rear wheel 54 and the rear wheel 54, the weight and position of the metal plate and the metal protrusion as a weight are determined appropriately so that the jumping height does not become as low as possible while making one turn to the side.

  Thus, in this embodiment, a balance weight as a weight is provided on the chassis 12 or a weight such as a disc is incorporated in the front wheel 44 or the rear wheel 54 to attach the weight to the vehicle body, so that the wheel is moved to the chassis when jumping. 12 makes it possible to perform high and stable jumping, and by making a difference in weight distribution on the left and right of the chassis 12 and wheels, it can rotate laterally at the time of jumping and is reliably stabilized by a wheel with low repulsive force that has a low repulsion structure. Thus, the traveling toy 10 can perform the landing and enjoy the traveling with changes.

Further, a balance weight provided on the chassis 12 is provided at the front end or the rear end of the chassis 12, and weights such as metal plates are attached to the left and right front wheels 44 or the left and right rear wheels 54 to change the weight balance between the front and rear, and when jumping forward Or, it may be flipped backwards.
Furthermore, when forming a wheel with a low resilience structure, a wheel with a different thickness of a wheel part or a hub formed by a synthetic resin is formed, and a wheel with a thicker wheel part or the like is made of a resin material having a large specific gravity as a weight. If the weights of the left and right wheels are made different by forming wheels with different weights to form the wheel portion, etc., and making the heavy wheels the left front wheel 44, the left rear wheel 54, the right front wheel 44, and the right rear wheel 54, In some cases, the weights of the front and rear wheels are made different from each other by using the heavy wheels as the left and right front wheels 44 or the left and right rear wheels 54.
