Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jumping toy.

[0002]

[Prior art]

 Conventionally, for example, a frog toy is known as a jumping toy. This frog toy is equipped with a frog toy body and a pump that sends air to the frog toy body.The pump sends air to the frog toy body, and the telescopic legs attached to the frog toy body are pneumatically actuated. It is configured to cause the frog toy body to make a jumping motion by temporarily expanding.

[0003]

[Problems to be solved by the device]

 However, in this frog toy, since the frog toy body and the pump are connected through the pipe, in order to move the frog toy body forward, the operator also has to move forward and the pump It was troublesome because it was necessary to continuously supply the air from. In addition, since the frog toy body was designed to bounce by the operator's pump operation, the jumping timing of the frog toy body was also known, which was not surprising. In addition, when multiple frog toys were prepared and several people competed with each other, the victory or defeat would never happen due to the number of pump operations, etc.

The present invention has been made in view of the above problems, and an object thereof is to provide a jumping toy that performs a jumping motion by itself and is surprising in the jumping motion.

[0005]

[Means for Solving the Problems]

 A first means is a battery, a motor driven by the battery, a rotating body that causes a toy to jump and bounce, and a power transmission that transmits the rotational power of the motor to the rotating body to rotate the rotating body. It is equipped with a mechanism and a plurality of cams (masters) which have different cam surface contour curves and which are rotated by the motor and have different angular velocities. Based on the operation, the elements forming the power transmission mechanism are connected and disconnected.

A second means is the same as the first means, wherein the rotating body lifts the front part of the toy by a reaction force received from the ground contact surface and kicks the ground contact surface to cause the toy to jump. The shape is such that

According to a third means, in the first means, the rotating body is composed of a meniscus rotatable about an eccentric position, and the meniscus is continuous with a boundary portion between a chord portion and an arc portion. Then, the arc portion is provided so as to be grounded.

A fourth means is a battery, a motor driven by the battery, a rotating body for causing a toy to make a jumping motion, and a rotational power of the motor transmitted to the rotating body to rotate the rotating body. It is equipped with a power transmission mechanism and a plurality of cams that have different cam surface contour curves and that are operated by the motor and have different operating speeds, and are in contact with these cams at the same time. Based on the operation of the follower, the elements composing the dynamic force transmission mechanism are connected and disconnected.

[0009]

[Action]

 According to the above-mentioned means, the bouncing toy bounces by the rotation of the rotating body by the rotational power of the motor. In this case, the combined action of multiple cams allows or hinders the transmission of the rotational power of the motor to the rotating body, but the operating speed (angular speed, etc.) of the multiple cams (nodes) is Because they are different, the timing of their acceptance and inhibition will change from one to the next. Therefore, it is not possible to predict when the jumping motion will be performed, which is very interesting. This makes it completely unknown which one wins when competing with the jumping toys, and it can be enjoyed anywhere and by anyone.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a frog toy, which is an example of a jumping toy. Reference numeral 1 designates the entire toy car. In the frog toy 1, when the operator 2 (see FIG. 2) on the waist is slid in the power-on direction, the frog toy 1 jumps irregularly. That is, the frog toy 1 floats up its front part, jumps several times in a row and rests for a few seconds, or jumps once and rests for a while. This operation is repeated irregularly. Then, this frog toy 1 starts to sound like a real frog, "Kero, Kero," only while it is at rest.

The frog toy 1 is roughly divided into a body 10 and a head 11. As shown in FIG. 2, the outer shell of the body portion 10 is composed of a front frame 10a and a rear frame 10b, and the front frame 10a and the rear frame 10b are assembled to each other by screwing. At that time, the mechanical box 3 shown in FIG. 3 is installed in the space surrounded by the front frame 10a and the rear frame 10b, and the notch 12, which is provided in the portion where the front frame 10a and the rear frame 10b are joined, The constricted part of the base of the arms 13 and 13 is fitted into the arm 12. Further, a head 11 to which a back plate 14 is screwed on the lower side is attached on the body 10 so as to be opened and closed by a pin 15. The upper portion of the coil spring 16 is inserted into the tubular portion 14a of the back plate 14, while the lower portion of the coil spring 16 is engaged with the boss 17 provided on the top plate of the rear frame 10b. The coil spring 16 has a function as a cushion when the mouth of the frog toy 1 is closed.

As shown in FIG. 3, the mechanical box 3 is composed of a lower frame 30, a middle frame 31, and an upper frame 32, which are assembled with each other by screwing. A battery box 33 is provided in the middle frame 31, and a battery (not shown) is housed in the battery box 33 from the front side thereof. In the space surrounded by the middle frame 31 and the upper frame 32, a motor M that is a driving source of the frog toy 1 is installed directly above the battery box 33. Then, as shown in FIG. 4, the rotational power of the motor M is transmitted to the gear 34j via the gears 34a, 34b, 34c, 34d, the worm 34e, the gear 34f, the worm 34g, the gear 34h, and the gear 34i. It has become. Of these, gears 34i and 34j are provided with cams (master nodes) 35 and 36 having cam surfaces on their end faces, respectively. The contour curves of the cam surfaces of the cams 35 and 36 are different. That is, in the cam 35, one wide ridge 35a is formed, and in the cam 36, four narrow ridges 36a are locally formed. Further, the numbers of teeth of the gears 34i and 34j are slightly different, and as a result, the angular velocities of the cams 35 and 36 are different. One end (contact portion 37a) of a lever (follower) 37 can simultaneously contact the cam surfaces of the cams 35 and 36. The lever 37 is fixedly provided on the same shaft 39 as the gear 34d and the worm 34e, and a torsion coil spring 38 hung between the lever 37 and the middle frame 31 causes the contact portion 37a to contact the cams 35 and 36. Applied to the surface.

Further, the shaft 39 is provided with a gear (sun gear) 40 integrally formed with the gear 34d. A gear (planetary gear) 41 attached to the other end of the lever 37 (the end opposite to the contact portion 37a) meshes with the gear 40. Therefore, when the lever 37 is rotated about the shaft 39 by the cams 35 and 36, the gear 41 revolves around the gear 40. Gears 42 and 43 that rotate integrally with the gear 41 are attached to the other end of the lever 37.

Then, when the contact portion 37 a of the lever 37 is applied to the valley portion on the cam surface of the cams 35 and 36, the gear 42 meshes with the gear 44, and the rotational power of the motor M is generated by the gear 40, It is transmitted to the gear 44 via 41 and 42. Then, the meniscus (rotating body) 46 attached to the same shaft 45 as the gear 44 is rotated. The meniscus 46 is attached to the shaft 45 so that the chord portion is oriented so as to rotate before the arc portion. Then, due to the rotation of the meniscus 46, the front part of the frog toy 1 floats up or the frog toy 1 jumps. A surface clutch CL is provided between the gear 44 and the meniscus 46.

On the other hand, when one end of the lever 37 is abutted against the peaks 35 a and 36 a on the cam surfaces of the end cams 35 and 36, the gear 43 meshes with the gear 47 and the rotational power of the motor M is , And is transmitted to the gear 47 through the gears 40, 41, 43, and rotates the cam 49 attached to the same shaft 48 as the gear 47. Then, the pin 50 is moved up and down by the cam 49. The pin 50 penetrates the hole 32a of the upper frame 32 shown in FIG. 3 and the hole 10c of the body 10 shown in FIG. 2, and its upper end is in contact with the back plate 14 of the head 11. The vertical movement of 50 causes the head 11 to open and close. The opening / closing operation of the head 11 is the opening / closing operation of the mouth of the frog toy 1. At the same time, the rotational power of the motor M is transmitted to the rotary body 51 attached to the shaft 48 and partially formed with teeth on the peripheral surface thereof, and the teeth of the rotary body 51 repel the plastic piece 52, A cry similar to an actual frog is emitted.

In FIG. 3, SW indicates a power switch operated by the operator 2.

Next, the operation of the frog toy 1 will be described together with the operation.

First, when the operator 2 is slid in the power-on direction, the power switch SW is turned on and the motor M is driven to rotate. Then, the rotational power of the motor M is transmitted to the gear 34i and the gear 34j via the gears 34a, 34b, 34c, 34d, the worm 34e, the gear 34f, the worm 34g, and the gear 34h. Then, the cams 35 and 36 rotate in mutually opposite directions. In this case, since the gears 34i and 34j have slightly different numbers of teeth, the phases of the peaks 35a and 36a are slightly shifted as the cams 35 and 36 rotate, as shown in FIG.

When the contact portion 37a of the lever 37 comes into contact with the valleys of both the cams 35 and 36 (the position shown in FIG. 6), the gear 42 meshes with the gear 44 (see FIG. 7), Rotational power of the motor M is transmitted to the gear 44 via the gears 40, 41, 42 and causes the meniscus 46 to rotate. In this case, if the contact time of the contact portion 37a to the valleys of both the cams 35 and 36 is short, the front portion of the frog toy 1 temporarily rises and immediately returns to its original state, as shown in FIG. This floating operation mainly occurs when the contact portion 37a comes into contact with the valley of the portion where the peaks 36a of the cam 36 are dense. This is because in the valley where the peaks 36a of the cam 36 are dense, the meshing time of the gear 42 and the gear 44 is short, so the meniscus 46 rotates only slightly (state of FIG. 9), and the gear 42 This is because the state shown in FIG. 8 will be returned as the engagement between the gear and the toothed wheel 44 is released. On the other hand, if the contact time of the contact portion 37a to the valleys of both the cams 35 and 36 is long, the meniscus 46 rotates largely after passing through the state of FIG. 9 and gets over the meniscus 46 (state of FIG. 10). . At this time, the frog toy 1 makes one jumping motion. This jumping motion occurs when the contact portion 37a contacts the valley of the portion where the peaks 36a of the cam 36 are not dense. In this case, how many times the frog toy 1 continuously jumps depends on where the peak 35a of the cam 35 exists in the valley where the peaks 36a of the cam 36 are not dense.

When the contact portions 37a of the lever 37 come into contact with the peaks (35a, 36a) of either (or both) of the cams 35 and 36 as the cams 35 and 36 rotate (see FIG. 6 position), the gear 43 meshes with the gear 47, and the rotational power of the motor M is transmitted to the gear 47 via the gears 40, 41, 43, and the cam 49 attached to the same shaft 48 as the gear 47 is connected. Rotate and move the pin 50 up and down. Then, the frog toy 1 opens and closes its mouth. At the same time, the rotational power of the motor M is transmitted to the rotary body 51, and the teeth of the rotary body 51 cause the plastic piece 52 to be repelled, and a cry similar to an actual frog is emitted.

According to the frog toy 1 configured as described above, the frog toy 1 jumps by the rotation of the meniscus 46 by the rotational power of the motor M. In this case, the combined action of the cams 35 and 36 allows or hinders the transmission of the rotational power of the motor M to the meniscus 46, but since the angular speeds of the cams 35 and 36 are different, The timing of forgiveness / impediment will change from one to the next. Therefore, it is not possible to predict when the jumping motion will be performed, which is very interesting. This means that if you compete in the Kael Toy 1, you will never know which one will win, and you will be able to enjoy it anywhere and anyone. When this competition is conducted, the competition may be performed as it is, but a rail is laid, and on the other hand, a slot is formed on the lower surface of the frog toy 1 so as to engage with the rail. You may make it bounce along the.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the scope of the invention.

For example, although the frog toy 1 has been described as an example in the above embodiment, the present invention is also applicable to a jumping toy such as a rabbit toy or a horse toy.

Further, a direct acting cam may be provided instead of the cams 35 and 36 of the above embodiment. In this case, the linear cam may be operated by a rack and pinion mechanism or a link mechanism.

[Effect of device]

 As described above, according to the present invention, the jumping toy jumps by the rotation of the rotating body by the rotational power of the motor. In this case, the combined action of multiple cams allows or hinders the transmission of the rotational power of the motor to the legs, but the operating speed (angular velocity, etc.) of the multiple cams (nodes). However, the timing of acceptance and inhibition will change from one to the next. Therefore, it is not possible to predict when the jumping motion will occur, which is very interesting. This means that in the case of competition with the jumping toys, which one wins, there will be no result at all, and it will be enjoyed by anyone and everyone.
