[Detailed explanation of the invention] (Field of application of the invention) This invention is a traveling mechanism for a rolling toy that changes shape,
More specifically, the present invention relates to a traveling mechanism that allows a rolling spherical toy body to be driven by drive wheels.

(Prior Art) Generally, some rolling toys that change shape during rolling continue to roll even after the shape changes, and others stop rolling after the shape change. However, the former has the drawback that the fun of changing form cannot be seen while rolling, and the latter has the fault of not being able to see the fun of moving after changing form.

(Purpose of the invention) The purpose of this invention is to solve the above-mentioned drawbacks and to propose a traveling mechanism for a rolling toy that can change shape and travel after rolling.

(Means for achieving the objective) In order to achieve the above objective, the traveling mechanism of the rolling toy that changes form according to this invention has a form changing mechanism that changes form when divided into left and right parts, and also satisfies the following requirements. A traveling mechanism for a rolling toy that changes form.

(a) Inside the spherical running body that can be divided into left and right,
an elevating member that has a plurality of gear groups, is slidable up and down, and is biased downward by a spring;
(b) When the traveling body is divided by the dividing mechanism, the drive wheels provided at the bottom of the lifting member are provided with a dividing mechanism that divides the traveling body into left and right sides when rolling. (c) The top gear of the gear group is engaged with a rack provided in the vertical direction on the traveling body, and the gear of the gear group The lowermost gear meshes with a gear provided on the axle of the drive wheel. (Operation and effect of the invention) According to the above configuration, when the spherical running body is rolled, the starting piece hits the running surface and swings. As the gear moves, the engagement with the gear is released. At the same time, the splitting mechanism divides the traveling body into left and right parts, changing its shape, and the elevating member slides downward due to spring force, the driving wheels protrude from the traveling body, and at the same time, the gear group that meshes with the gears rotates. , the axle of the drive wheel is rotationally driven, so the toy travels. In this way, the spherical shape is divided into left and right sides and changes into other shapes, and it also travels, making it possible to provide an interesting and unexpected toy.

In this manner, when the activation piece hits the floor surface, the running toy starts running by using the starting piece as a tension, so that a surprising running toy can be obtained.

(Example) Hereinafter, embodiments of this invention will be described with reference to the drawings.

In the figure, symbol A indicates a shape-changing rolling toy. This is a traveling toy whose spherical shape is automatically divided into two parts and transformed into a robot-like shape by rolling.The rolling toy A has the following mechanisms.

(a) A mechanism that automatically divides the two hemispheres 1, 1 which form a spherical shape when they are butted together during rolling; (b) A mechanism that allows these hemispheres 1a, 1b to be stored inside when they form a spherical form. (c) A shape changing mechanism that changes the block-shaped traveling body 2 into a robot shape when the hemispheres 1a and 1b are divided. A traveling mechanism (d) that causes the toy A to protrude outward from the hemispheres 1a and 1b when it comes directly below it, and at the same time drives its driving wheels.(d) When the shape changes, the traveling body 2 is moved so that the chassis portion 4 is at the bottom. Posture holding mechanism that maintains the posture so that the posture is maintained.Next, each of the above-mentioned mechanisms will be explained in sequence.

(a) About the automatic splitting mechanism Hollow hemispheres 1 are placed on both sides of the traveling main body 2 in the direction of travel.
a, 1b are provided so that the spherical surfaces are on the outside of each other, and each of the hemispheres 1a, 1b is provided with a circular partition 5 parallel to its opening surface approximately in the middle, and the center of each partition 5, 5 is provided approximately in the middle thereof. Connecting shafts 6a and 6b are provided respectively from the connecting shafts 6a and 6b, and one connecting shaft 6a is inserted into the other connecting shaft 6b so as to be slidable but not idling. Furthermore, both hemispheres 1
a, 1b are connected by two links 7, 7. These links 7, 7 are provided so as to be expanded by springs 8, so that the two hemispheres 1a, 1b are always urged to be separated from each other. On the other hand, a hook 9 is formed at the tip of the connecting shaft 6b of the one hemisphere 1b, and when the two hemispheres 1a and 1b are close to each other and formed spherically, the hook 9 is It penetrates from the central opening 12 of the partition wall 5 of the hemispherical body 1a and is locked to a first operating piece 10 swingably provided inside the partition wall 5. One end of the first actuating piece 10 is pivotally supported by the partition wall 5 and urged toward the center of the partition wall 5 by a spring 13.
It is formed to ensure engagement with the hook 9.

On the other hand, a release mechanism is provided on the partition wall 5 of the hemisphere 1a to release the lock between the hook 9 and the first operating piece 10 while the toy A is rolling. As shown in FIGS. 4 to 6, this release mechanism fixes one end of a weight 15 to a rotating shaft 14 that is rotatably fitted into a connecting shaft 6a of the hemisphere 1a, and also fixes one end of a weight 15 to a first gear 16. The first gear 16 is connected to a second gear 18 which is decelerated via an intermediate gear 17, and the first actuating piece 10 is biased on the back side of the second gear 18. a cam 19 that engages the side end;
It is made up of the following. Therefore, when toy A is rolled in the direction along the dividing plane, hemisphere 1
While weights a and 1b roll, the weight 15 is always held downward, so their relative movement causes the first
The intermediate gear 17 that meshes with the gear 16 and the second gear 18 that meshes with the intermediate gear 17 rotate, and at the same time, the cam 19 rotates. As the cam 19 rotates, it pushes out the first actuating piece 10 against the force of the spring 13, so that the engagement between the first actuating piece 10 and the hook 9 is released (FIG. 5). This release operation causes
Due to the force of springs 8 provided on the links 7, 7, both hemispheres 1a, 1b are pushed outward from each other, and the toy A is divided into two.

The second gear 18 has one end pivotally supported by the partition wall 5 and has a second actuating piece 11 that swings within a certain range.
It is supported in the direction of the first actuating piece 10 by a pulling spring 20 provided on the second gear 18 and the partition wall 5 . The force of this pulling spring 20 is set larger than the force of the spring 13 that biases the first actuating piece 10. For this reason, the second
The gear 18 is connected to the intermediate gear 1 by the pull spring 20.
It is held in a position where it does not mesh with 7. By the way, an opening 21 is formed at a position corresponding to the tip of the second operating piece 11 of the hemisphere 1a, and when the toy A is closed, an opening 21 is formed on the other hemisphere 1b side. The engaged piece 22 is penetrated, and its tip engages with the tip of the second actuating piece 11, and the second actuating piece 1 resists the force of the pulling spring 20.
1 is pushed back, and the second gear 18 and intermediate gear 17 are engaged with each other.

When the toy A is divided, the engaging piece 22 is connected to the opening 2.
1, the second actuating piece 11 is moved between the second gear 18 and the intermediate gear 1 by the force of the pulling spring 20.
At the same time, the second gear 18 also returns by the amount of rotation, and the relative position between the cam 19 and the first actuating piece 10 also returns (FIG. 6). In addition,
The engagement piece 22 is provided on the traveling main body 2, which will be described later.

In order to return the divided hemispheres 1a, 1b to their original spherical form, both hemispheres 1a, 1b are pushed in from the outside, and the hook 9 of the connecting shaft 6b of one hemisphere 1b is inserted into the other hemisphere 1a. What is necessary is just to make it protrude from the opening part 12 of the partition 5, and to make it lock with the 1st actuation piece 10. At the same time, the engagement piece 22 also moves to another opening 2.
1 and engages with the second actuating piece 11.

(b) Regarding the shape change mechanism The traveling main body 2 consists of three opposing plate-like pieces 23a, 2
3b and 23c are connected by a plurality of connecting rods 24 to form a block shape as a whole, and a robot head piece 25 is attached to the upper end of one plate-like piece 23a and is rotated by a spring (not shown). U-shaped pieces 26a, 26 are freely provided and are connected to each other in a bendable manner at the end of the same side of the other plate-shaped piece 23c.
b is attached to the plate-like piece 23c via a spring (not shown).
It is foldably connected on the surface. In the traveling main body 2, the connecting rod 24a at the center of the upper end is coaxial with the central support shaft 7a of the links 7, 7 connected to the aforementioned two hemispheres 1a, 1b. For this reason, the third
As shown in the figure, the traveling body 2 is always located at the center of the links 7, 7, that is, between the two hemispheres 1a, 1b. Further, the traveling main body 2 is formed so that when the head piece 25 and the U-shaped piece are folded, they are housed in a space created inside the hemispheres 1a and 1b when they are butted together. Therefore, when the toy A is closed, the head piece 2 of the traveling body 2 stored inside
5 and U-shaped pieces 26a, 26b are hemispheres 1a, 1
Although it is in a state where it cannot be deployed because it is engaged with the inner wall of b, when it is divided, the traveling main body 2 becomes both hemispheres 1a,
1b, the force of each spring is released, the head piece 25 and the U-shaped pieces 26a, 26b stand up, and the traveling main body 2 forms a body part and takes on a robot-like form as a whole.

(c) About the traveling mechanism One plate-like piece 23a and 23b of the traveling main body 2
A storage space is formed in the vertical direction inside the storage space, and an elevating member 3 having a plurality of gear groups G therein is housed in a vertically slidable manner. The uppermost gear G1 of the gear group G meshes with a rack 28 provided vertically inside the plate-shaped piece. Further, the elevating member 3 is provided with a protrusion 30 that protrudes to the outside through a notched groove 29 formed along the rack 28.
A pull spring 31 is provided at the bottom of a.
As a result, the elevating member 3 is always urged downward by the pulling spring 31.

Next, a chassis section 4 is provided at the lower part of the elevating member 3, and a driving front wheel 32,
A rear wheel 33 is provided at the rear. A gear 34 is provided on the axle 32a of the front drive wheel 32, and the gear 34 meshes with the lowermost gear G4 of the gear group G, and the gear G4 is supported by a bearing portion 35 in the shape of an elongated hole. When the traveling main body 2 is divided, the driving front wheels 3 as driving wheels are connected to the elevating member 3.
It is provided so that it can move in and out of the traveling body 2 according to the vertical movement of the wheel, and rotates in the forward direction (clockwise rotation in the figure).
is configured to do so.

Further, a notch groove 36 and a bearing portion 37 are formed in the front-rear direction approximately at the center of the chassis portion 4, and the bearing portion 3
A starting piece 38 is supported by a bearing on 7, and one end of the starting piece 38 projects outward from the notched groove 36 by a spring 39, and the other end engages with the gear 34 of the front driving wheel 32. energized. Since the activation piece 38 is applied to and engaged with the gear 34 of the front wheel 32 from below, rotation of the axle shaft 32a in the forward direction is prevented.

When the elevating member 3 is stored in the storage space of the traveling main body 2, it is constructed so that it is simultaneously stored inside the two hemispheres 1a and 1b together with the traveling main body 2. A protruding piece 40 is formed at the rear end of the chassis portion 4, and the protruding piece 40 is arranged so as to be engaged with the folded ends of the U-shaped pieces 26a and 26b when the vehicle is lifted and stored. .

In the above configuration, when the elevating member 3 is moved upward and stored in the storage space of the traveling main body 2, the elevating member 3 is urged to be moved downward by the pulling force of the attracting spring 31. However, when moving downward, the gear group G meshed with the rack 28 and the gear 34 on the axle 32a of the front wheel 32 must rotate, but since the gear 34 is engaged with the activation piece 38, , the rotation of the gear group G is prevented, and therefore the gear G1 at the top is held in a state of meshing with the top of the rack 28, the release of the spring force of the pulling spring 31 is suppressed, and the lifting member 3 is moved downward. I can't move.

On the other hand, the connection 24 at the center of the upper end of the traveling main body 2
a is a link 7 connected to both hemispheres 1a and 1b;
It is coaxial with the central support shaft 7a of No.7. Therefore, when the toy A rolls and the hemispheres 1a and 1b are divided into left and right sides, the links 7 and 7
opens and the central support shaft 7a of the links 7, 7 descends, so that when the traveling body 2 exits from between the hemispheres 1a, 1b, it also descends lower than before the division. Therefore, one end of the activation piece 38 also protrudes to the outside of the hemispheres 1a, 1b. Therefore, when the activation piece 38 hits the running floor surface when the toy A rolls, the activation piece 38 is pushed back inside the chassis part 4 against the force of the spring and swings, so that the other end Gear 34 of front wheel axle 32a
will be disengaged. Therefore, the spring force of the pulling spring 31 is released, the elevating member 3 moves downward, and the front drive wheel 32 protrudes from the traveling body 2 together with the chassis portion 4. At this time, the gear group G that meshes with the rack 28 is operated, and the axle of the front wheel is also rotationally driven in the forward direction. Therefore, toy A is equipped with the chassis section 4.
It runs on wheels. The lowermost gear G4 of the gear group G is supported by an elongated bearing 35, and is in a position to transmit the rotation to the front wheel gear 34 when the upper gear group is rotating. When the elevating member 3 moves to the lowest position and the rotation of the gear group G stops, the rotation of the gear 34 of the front wheel 32, which rotates in the forward direction due to inertia, causes the bearing part 35 to move in the opposite direction. It runs away to the side, allowing the front wheels to rotate forward. Therefore, the lifting member 3
Even when the toy A moves downward, the front wheels continue to rotate, allowing the toy A to run smoothly.

(d) About the posture holding mechanism By the way, in order for the toy A to roll and split as described above, and for the whole toy A to change form into a robot shape and continue to run smoothly, the robot head piece 25 must be placed at the top. The attitude of the traveling main body 2 must be maintained so that the chassis portion 4 is at the bottom. This is achieved by rotatably providing posture holding legs 42, 42 on the outside of the front and rear plate-like pieces 23a, 23c of the traveling main body 2, and holding the posture holding legs 42, 42 by springs (not shown). This is done by a posture holding mechanism configured by urging the legs outward so that the legs can be opened in a letter-shaped manner. Posture maintaining legs 42, 42 are the traveling main body 2
It has a length sufficient to maintain this posture, and a long stabilizing piece 42a is provided on the left and right sides at its tip.

Therefore, at the same time as the toy A rolls and is divided into left and right parts, the front and rear parts of the traveling main body 2, that is, the chassis part 4
The posture maintaining legs 42, 42 are biased by springs at the front and rear of the body, and are opened in a V-shape and protrude to the outside. In this case, the tip 42a of one of the posture maintaining legs 42 will come into contact with the rolling floor surface in front of the rolling surface of the toy A, so that the rolling of the toy A will be prevented and the chassis section 4 will move downward. is held in position. Since the chassis section 4 is provided with wheels, the toy A runs stably on the wheels of the chassis section 4 due to inertia during rolling.
