Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a front view of a mobile toy, fig. 2 is a view from the direction a of fig. 1, fig. 3 is a view from the direction B of fig. 1, fig. 4 is a cross-sectional view taken along the line C-C of fig. 3, fig. 5 is a cross-sectional view taken along the line D-D of fig. 3, fig. 6 is an exploded perspective view of the mobile toy, fig. 7 is an explanatory view of the operation of the mobile toy as viewed from the side, and fig. 8 is an explanatory view of the operation of the mobile toy as viewed from the front.

The moving toy 10 shown in fig. 1 to 8 is a toy that descends by its own weight on a gentle inclined surface SL (see fig. 7) of, for example, α ° (about 5 °). The moving toy 10 does not have a power source and moves downward on the inclined surface SL by its own weight.

The mobile toy 10 includes a hollow main body 20. The main body 20 includes a 1 st main body 21 formed of a resin material such as plastic into a substantially bowl shape, and a 2 nd main body 22 formed of a resin material such as plastic into a substantially bowl shape as in the 1 st main body 21. The body 20 is formed into a substantially spherical shape by abutting the 1 st body 21 and the 2 nd body 22 against each other.

The 1 st body 21 is disposed on the moving direction side of the moving toy 10, i.e., in front of the moving direction. On the other hand, the 2 nd body 22 is disposed on the opposite side of the moving direction of the moving toy 10, that is, behind the moving direction. The 1 st body 21 has a face FC of a character formed on an outer surface thereof by printing or the like. That is, the face FC of the character is provided on the moving direction side of the main body 20.

As shown in fig. 5 and 6, the 1 st body 21 is provided with a total of 3 engaging convex portions 21a (only 1 is shown in fig. 5, and only 2 is shown in fig. 6). On the other hand, the 2 nd main body 22 is provided with a total of 3 engaging recesses 22a (only 1 is shown in fig. 5). The 1 st body 21 and the 2 nd body 22 are assembled with each other by inserting the engaging convex portions 21a into the engaging concave portions 22a, respectively.

Here, an adhesive (not shown) is applied between the 1 st body 21 and the 2 nd body 22. This makes it difficult for the 1 st and 2

nd bodies

21, 22 to be detached from each other.

As shown in fig. 5, a partition wall 20a is provided inside the main body 20. The partition wall 20a is formed by a 1 st partition wall 21b and a 2 nd partition wall 22b, the 1 st partition wall 21b forming a 1 st main body 21, and the 2 nd partition wall 22b forming a 2 nd main body 22. The partition wall 20a partitions the interior of the main body 20 into a hollow chamber 20b on the side away from the inclined surface SL and a roller mechanism housing chamber 20c on the side close to the inclined surface SL.

This prevents foreign matter such as dust from entering from the roller mechanism housing chamber 20c side (outside) to the hollow chamber 20b side (inside), and keeps the moving toy 10 clean. In addition, the roller mechanism 30 is housed in the roller mechanism housing chamber 20c.

Further, a 1 st bolt hole (female screw) 21c is provided in the 1 st body 21 disposed forward in the moving direction of the moving toy 10. On the other hand, a 2 nd bolt hole (female screw) 22c is provided in the 2 nd body 22 disposed rearward in the moving direction of the moving toy 10. A fixing bolt (male screw) SC is screwed to each of the 1 st bolt hole 21c and the 2 nd bolt hole 22c. Thereby, the roller mechanism 30 is fixed to both the 1 st body 21 and the 2 nd body 22 forming the body 20.

In the above description, the 1 st body 21 is disposed forward in the moving direction and the 2 nd body 22 is disposed rearward in the moving direction, but even if the 2 nd body 22 is disposed forward in the moving direction and the 1 st body 21 is disposed rearward in the moving direction, the moving toy 10 can move downward on the inclined surface SL. Therefore, the 2 nd main body 22 can be provided with the face FC of a character on the outer surface thereof. That is, the face FC of the character may be provided on the opposite side of the moving direction of the main body 20. Further, the 1 st body 21 and the 2 nd body 22 may be provided with character faces FC on their outer surfaces.

The roller mechanism 30 housed in the roller mechanism housing chamber 20c swings the main body 20 including the 1 st main body 21 and the 2 nd main body 22 in the front-rear direction and the left-right direction, and moves on the inclined surface SL (see fig. 7 and 8). In other words, the roller mechanism 30 is a functional component necessary for enhancing the interest of the moving toy 10.

Since roller mechanism 30 is housed in roller mechanism housing chamber 20c, the portion of moving toy 10 on the side closer to inclined surface SL becomes heavy. Therefore, as shown in fig. 5, the center of gravity G of the moving toy 10 is located closer to the partition wall 20a (closer to the roller mechanism 30 and the inclined surface SL) than the center portion of the main body 20. The moving toy 10 moves with its center of gravity G swinging in the front-back direction and the left-right direction, and moves downward on the inclined surface SL with an interesting motion.

The roller mechanism 30 includes a base member 31 formed of a resin material such as plastic into a substantially disk shape. The base member 31 corresponds to a facing member of the present invention, and is provided on the main body 20 so as to face the inclined surface SL.

A roller support portion 31a is provided at the center of the base member 31. Further, on both sides of the base member 31 centering on the roller support portion 31a, a 1 st recessed portion 31b and a 2 nd recessed portion 31c, which are recessed in the axial direction of the base member 31 with respect to the roller support portion 31a, are provided. That is, the thickness of the roller support portion 31a is larger than the depth of the 1 st and 2 nd

concave portions

31b and 31c.

Here, as shown in fig. 6, when a line segment extending along the moving direction of the moving toy 10 is a 1 st line segment LN1, and a line segment orthogonal to the 1 st line segment LN1 is a 2 nd line segment LN2, the longitudinal direction of the roller support portion 31a coincides with the extending direction of the 2 nd line segment LN 2.

The roller support portion 31a is provided with a roller receiving hole 31d formed in a substantially elliptical shape. The longitudinal direction of the roller accommodating hole 31d also coincides with the extending direction of the 2 nd line segment LN2, and the roller accommodating hole 31d penetrates in the thickness direction of the base member 31.

Further, the roller support portion 31a is provided with a pair of shaft holes 31e extending in the extending direction of the 2 nd line segment LN 2. Both longitudinal sides of a rotary shaft 32 made of a round steel rod are inserted into the pair of shaft holes 31e. The rotating shaft 32 rotatably supports the barrel roller 33, and thereby the barrel roller 33 can rotate clockwise and counterclockwise in the case shown in fig. 5 inside the roller accommodating hole 31d.

The barrel roller 33 accommodated in the roller accommodating hole 31d is formed in a substantially barrel shape from a resin material such as plastic. Specifically, the barrel roller 33 is formed in a shape in which the diameter thereof gradually decreases from the center in the longitudinal direction toward both sides in the longitudinal direction. That is, as shown in fig. 4, the longitudinal center of the barrel roller 33 has a diameter d1, and both longitudinal sides of the barrel roller 33 have a diameter d2 smaller than the diameter d1 (d 2 < d 1).

Here, the barrel roll 33 corresponds to the rotating body of the present invention. The barrel roller 33 rotates about a rotary shaft 32 provided in the base member 31, and can smoothly roll on the inclined surface SL.

Further, a plurality of recesses 33a are provided on the outer peripheral surface of the barrel roller 33. These recesses 33a are arranged to extend in the circumferential direction of the barrel roller 33, and a plurality of recesses are arranged in the axial direction of the barrel roller 33.

By extending the plurality of recesses 33a in the circumferential direction of the barrel roller 33 in this way, the barrel roller 33 can roll stably and smoothly even on a gentle inclined surface SL. Assuming that the barrel roller 33 is provided with a plurality of recesses extending in the axial direction, the following may also occur: the barrel roller 33 rolls unstably on the inclined surface SL, and the moving toy 10 stops on the inclined surface SL.

When the barrel roll 33 is molded, the plurality of recesses 33a function as so-called "material reducing portions". That is, the plurality of recesses 33a effectively suppress the occurrence of indentations, voids, and the like in the barrel roller 33 at the time of curing after injection molding of the barrel roller 33. Therefore, it is possible to prevent the occurrence of strain during molding of the barrel roll 33, and further, it is possible to realize a barrel roll 33 with high dimensional accuracy.

Further, by making the barrel roll 33 of plastic and providing a plurality of recesses 33a, the barrel roll 33 is not only reduced in weight, but also reduced in friction against the inclined surface SL. Therefore, the barrel roller 33 does not increase the movement resistance of the moving toy 10 with respect to the inclined surface SL. Thereby, the moving toy 10 can smoothly move on the inclined surface SL.

As shown in fig. 4, the outer peripheral surface of the barrel roller 33 is circular arc-shaped with a relatively large radius of curvature R. Specifically, the curvature radius R of the outer peripheral surface of the barrel roller 33 is larger than the curvature radius (not shown) of the outer peripheral surface of the substantially spherical body 20.

As a result, as shown in fig. 8, the moving toy 10 moves downward the inclined surface SL by its own weight while swinging on the inclined surface SL in the lateral direction. This increases the interest of the moving toy 10.

As shown in fig. 5 and 6, the 1 st recessed portion 31b and the 2 nd recessed portion 31c are provided with bolt through holes 31f respectively so as to penetrate through the 1 st recessed portion 31b and the 2 nd recessed portion 31c in the thickness direction. The fixing bolts SC are inserted through the pair of bolt insertion holes 31f. Thereby, the roller mechanism 30 is fixed to the main body 20 in a state of being accommodated in the roller mechanism accommodation chamber 20c.

Further, the bolt head of the fixing bolt SC also enters the inside of the bolt through hole 31f. Thereby, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b formed in a flat plate shape can be stuck to the 1 st recessed portion 31b and the 2 nd recessed portion 31c, respectively.

The 1 st and 2 nd recesses 31b and 31c are identical in shape to each other and formed in a crescent shape. Crescent-shaped 1 st synthetic rubber 34a and 2 nd synthetic rubber 34b made of silicone or the like are adhered to the 1 st recessed portion 31b and the 2 nd recessed portion 31c, respectively. These 1 st synthetic rubber 34a and 2 nd synthetic rubber 34b are also formed in the same shape as each other. In addition, the 1 st and 2 nd recesses 31b and 31c and the 1 st and 2 nd

synthetic rubbers

34a and 34b formed in the same shape in the present embodiment are not necessarily the same as each other, and may be different from each other as long as the later-described swinging in the front-rear direction of the mobile toy 10 on the inclined surface SL can be achieved. The 1 st synthetic rubber 34a is adhered to the 1 st recessed portion 31b on the front side in the moving direction of the base member 31, and the 2 nd synthetic rubber 34b is adhered to the 2 nd recessed portion 31c on the rear side in the moving direction of the base member 31. The 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are fixed to the 1 st recessed portion 31b and the 2 nd recessed portion 31c, respectively, with a double-sided tape or the like (not shown).

As shown in fig. 5, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b slightly protrude from the base member 31 toward the inclined surface SL (downward in the drawing, in a direction away from the surface of the base member 31 facing the inclined surface). Thereby, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b can be brought into contact with the inclined surface SL, respectively, in accordance with the movement of the moving toy 10 on the inclined surface SL.

Here, the 1 st synthetic rubber 34a corresponds to the 1 st contact member of the present invention, and is provided on the moving direction side of the base member 31. On the other hand, the 2 nd synthetic rubber 34b corresponds to the 2 nd contact member of the present invention, and is provided on the opposite side of the base member 31 to the moving direction side centering on the barrel roller 33. In this manner, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are arranged in mirror symmetry on both sides thereof with the barrel roller 33 as a center in the moving direction of the moving toy 10 (refer to fig. 3).

In addition, as shown in fig. 5, the barrel roller 33 protrudes from the base member 31 than the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b. Specifically, the barrel roll 33 protrudes by the height dimension H (for example, about 2.0 mm) more than the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b.

Thereby, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b can come into contact with the inclined surface SL in accordance with the forward and backward swinging of the moving toy 10 on the inclined surface SL (see fig. 7).

Here, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are made of rubber such as silicone, and the barrel roll 33 is made of plastic. Therefore, the frictional force of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b against the inclined surface SL is larger than that of the barrel roller 33 against the inclined surface SL. That is, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are less likely to slip against the inclined surface SL than the barrel roller 33.

Thus, when the moving toy 10 descends on the inclined surface SL and the 1 st synthetic rubber 34a comes into contact with the inclined surface SL, braking (striking) is applied. Then, since the inclined surface SL is at a gentle angle (α °), the 2 nd synthetic rubber 34b comes into contact with the inclined surface SL this time in reaction thereto. Thereafter, the moving toy 10 descends on the inclined surface SL with the rotation of the barrel roller 33, and the center of gravity G moves forward in the moving direction. Thereby, the 1 st synthetic rubber 34a comes into contact with the inclined surface SL again. Such a series of operations of the moving toy 10 (an operation of swinging in the front-rear direction) is repeated on the inclined surface SL (see fig. 7).

In other words, the moving toy 10 can take the following two states during the movement of the inclined surface SL: the 1 st state (forward tilted posture state) in which the barrel roller 33 and the 1 st synthetic rubber 34a are in contact with the inclined surface SL and the 2 nd synthetic rubber 34b is separated from the inclined surface SL, and the 2 nd state (backward tilted posture state) in which the barrel roller 33 and the 2 nd synthetic rubber 34b are in contact with the inclined surface SL and the 1 st synthetic rubber 34a is separated from the inclined surface SL.

Further, as shown in fig. 3, when the mobile toy 10 is viewed from the base member 31 side (bottom side), the barrel roller 33 has a length L1 shorter than the length L2 of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b in the axial direction of the rotary shaft 32 (L1 < L2). Further, synthetic rubber non-disposed portions (contact member non-disposed portions) SP are disposed in the portion of the roller support portion 31a of the base member 31 and on both sides in the longitudinal direction of the barrel roller 33, and the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are not disposed in the synthetic rubber non-disposed portions (contact member non-disposed portions) SP. That is, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are disposed apart from each other centering on the barrel roller 33. Since the synthetic rubber non-disposed portion SP is a region where the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are not disposed in a protruding state, the distance from the inclined surface SL at the facing surface of the base member 31 facing the inclined surface becomes large, and contact with the inclined surface SL is prevented or suppressed.

As a result, the right and left end portions of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are independently in contact with the inclined surface SL, respectively, in accordance with the swing of the movable toy 10 in the left-right direction on the inclined surface SL (see fig. 8), and the movable toy 10 descends while meandering in the left-right direction little by little on the inclined surface SL. This also increases the interest of the mobile toy 10. Further, by providing the synthetic rubber non-disposed portion (contact member non-disposed portion) SP, it is possible to suppress the generation of a frictional force in a direction orthogonal to the moving direction, and to suppress the movement from being stopped by the frictional force.

As shown in fig. 3, the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are formed in a crescent shape, and the width w1 of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b in the center in the longitudinal direction is larger than the width w2 on both sides in the longitudinal direction (w 1 > w 2). That is, the width of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b in the center portion in the longitudinal direction is wider than the width of both sides in the longitudinal direction.

Since the moving toy 10 swings back and forth on the inclined surface SL (see fig. 7), a portion (a hatched portion in fig. 3) of the 1 st synthetic rubber 34a in the front in the moving direction, particularly, the center in the longitudinal direction and the front in the moving direction is easily worn. Here, by making the width w1 of the 1 st synthetic rubber 34a in the center portion in the longitudinal direction larger than the width w2 of both sides in the longitudinal direction, the portion of the 1 st synthetic rubber 34a in the center portion in the longitudinal direction close to the barrel roller 33 can also come into contact with the inclined surface SL, and the function as the 1 st synthetic rubber 34a can be exhibited for a long period of time.

Thereby, the moving toy 10 can swing in the front-rear direction on the inclined surface SL for a long period of time. In addition, when the 2 nd main body 22 is disposed forward in the moving direction, the 2 nd synthetic rubber 34b can be said to be the same as described above.

Next, the operation of the mobile toy 10 formed as described above will be described in detail with reference to the drawings.

First, as shown in operation (1) of fig. 7, the first body 21 of the face FC with a character is oriented forward in the moving direction, and the moving toy 10 is placed on the inclined surface SL. Then, the barrel roller 33 rotates, and the center of gravity G of the moving toy 10 moves to the moving direction side. Then, the moving toy 10 is tilted as indicated by a broken-line arrow R1 to be in a forward-tilted posture. Thereby, in a state where the barrel roller 33 is in contact with the inclined surface SL, the 1 st synthetic rubber 34a is in contact with the inclined surface SL to apply braking (1 st state). At this time, the 2 nd synthetic rubber 34b is separated from the inclined surface SL.

Thereafter, as shown in action (2) of fig. 7, the moving toy 10 is tilted as indicated by a broken-line arrow R2, and is brought into a tilted-back posture. That is, the center of gravity G moves to the opposite side of the moving direction. Therefore, in a state where the barrel roller 33 is in contact with the inclined surface SL, the 2 nd synthetic rubber 34b is in contact with the inclined surface SL (2 nd state). At this time, the 1 st synthetic rubber 34a is separated from the inclined surface SL.

Then, the center of gravity G of the mobile toy 10 moves forward in the moving direction, and the barrel roller 33 rotates, so that the mobile toy 10 descends on the inclined surface SL by its own weight. As shown in action (3) of fig. 7, the mobile toy 10 is in the forward tilted posture state (the same state as action (1)). After the action (3) in fig. 7, the moving toy 10 is in the backward tilted posture (the same state as the action (2)) as shown in the action (4) in fig. 7.

Here, as shown in fig. 7, the period from the state of the action (1) to the state of the action (3) is "1 cycle" of the oscillating motion in the front-rear direction of the moving toy 10. In fig. 7, for the sake of convenience of explanation, in order to easily understand "1 cycle" of the swing motion of the moving toy 10, "1 cycle" is represented longer as indicated by a solid arrow. However, in practice, the "1 cycle" of the swing motion of the moving toy 10 is an extremely short cycle of the moving distance of about several millimeters.

As described above, as shown in the operations (1) to (4), the movable toy 10 placed on the inclined surface SL swings back and forth while being repeatedly shaken, and moves downward on the inclined surface SL by its own weight with a fun action. That is, the moving toy 10 alternately repeats the 1 st state as the forward tilted posture state and the 2 nd state as the backward tilted posture state, and moves downward on the inclined surface SL.

At this time, for example, as shown in fig. 8, when the inclined surface SL is inclined to the right or left in the movement direction, the moving toy 10 also swings in the left-right direction as shown in the action (5) and the action (6). That is, the moving toy 10 performs a more fun action of adding a swing motion in the left-right direction to a swing motion in the front-back direction.

Specifically, when inclined surface SL is inclined to the right in the moving direction, moving toy 10 is inclined to the right as indicated by broken-line arrow R3 in action (5). That is, the center of gravity G moves to the right in the moving direction. On the other hand, when inclined surface SL is inclined to the left in the moving direction, moving toy 10 is inclined to the left as indicated by broken-line arrow R4 in action (6). That is, the center of gravity G moves to the left in the moving direction.

Further, even in the case where the inclined surface SL is not inclined to the right or left in the moving direction, the barrel roller 33 is formed in a shape in which the diameter thereof gradually decreases from the center in the longitudinal direction toward both sides in the longitudinal direction, and therefore, the center of gravity G of the moving toy 10 is easily moved to the right and left in the moving direction, respectively. Thus, even when the inclined surface SL is not inclined to the right or left in the moving direction, the moving toy 10 performs a fun action of adding the rocking motion in the left-right direction to the rocking motion in the front-back direction as described above in accordance with the contact between the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b and the inclined surface SL.

In this manner, the movable toy 10 is moved downward while swinging in the front-rear direction and the left-right direction on the inclined surface SL by the function of the roller mechanism 30. However, the moving toy 10 can perform more complicated swing motions depending on the shape of the inclined surface SL (concave shape, convex shape), the angle of the inclined surface SL, and the raw material of the inclined surface SL (different friction coefficients).

For example, the following operations may be performed: the second synthetic rubber 34b at the rear in the moving direction does not contact the inclined surface SL, and only the first synthetic rubber 34a at the front in the moving direction swings little by little while repeating contact and separation with and from the inclined surface SL, and descends on the inclined surface SL by the rotation of the barrel roller 33.

As described above in detail, according to the present embodiment, the barrel roll 33, the 1 st synthetic rubber 34a, and the 2 nd synthetic rubber 34b can be used to simplify the structure by moving on the inclined surface SL with a fun motion.

The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made within the scope not departing from the gist thereof. For example, in the above-described embodiment, the case where the raw materials of the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b are both made of the same raw material (silicone or the like) is described, but the present invention is not limited to this, and the 1 st synthetic rubber 34a and the 2 nd synthetic rubber 34b may be formed using raw materials having different frictional forces with respect to the inclined surface SL.

The material, shape, size, number, installation location, and the like of each component of the above-described embodiments are arbitrary, and are not limited to the above-described embodiments, as long as the present invention can be achieved.
