Description

[Detailed explanation of the invention] (Industrial application field) This invention can be used on both water and land.
This invention relates to an amphibious mobile toy that can move while freely avoiding obstacles.

(Prior art) Conventionally, devices have been equipped with both screws and running wheels, and have been used to propel the device over the water surface of bathtubs, pools, etc.
Amphibious mobile toys that can be played by running on land are known (for example,
No. 56390, Utility Model No. 58-142099).

(Problem to be solved by the invention) However, the above-mentioned conventional amphibious moving toys cannot change direction if they run straight and hit the edge of a bathtub or pool, or an obstacle on land. The problem was that if you couldn't do it, you would end up stuck in one spot, and you wouldn't be able to avoid the obstacles unless you manually changed the direction, which was troublesome and easy to lose interest.

This invention was made with the aim of solving the above problems and providing an amphibious mobile toy that can automatically avoid obstacles and the like.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the amphibious mobile toy according to the present invention has a power source and a power transmission mechanism housed in a floating body, and a gear and a gear that rotate via the power transmission mechanism. A screw and a driving wheel are respectively provided to rotate outside the floating body, and a circular plate-shaped rotating member having an inner circumferential tooth portion that meshes with the gear is rotatably mounted on the floating body, and an eccentric frame is attached to the rotating member. The floating body is mounted vertically, a cover is mounted on the floating body, a neck member is rotatably supported on the cover, a lever is connected to the shaft of the neck member, and the lever is biased to move within the eccentric frame. It is constructed by coming into contact with a part of the eccentric frame.

(Function) If the rotating member is rotated while the amphibious moving toy is moving in the water or on land, when the amphibious moving toy moves forward and approaches an obstacle, the rotating member will rotate when the amphibious moving toy approaches an obstacle. The rotating contact allows the entire toy to change direction to avoid obstacles and advance further.

(Example) What is shown in FIG. 1 is an amphibious mobile toy 1 according to an embodiment of this invention, which includes a hollow body 2 that floats on water, a power source 3 installed inside the body 2,
moving means 4, 41, 42, 43 for moving the main body 2 on land and water by the power of the power source 3; The structure includes an annular rotating member 5.

In the main body 2, the deep dish-shaped floating body 21 and the cover 22 are joined by screws 6 etc. screwed in from the bottom side of the floating body 21, and the whole body 2 is made into a hollow body in the shape of a water bird. It is being Further, a neck member 22a in the shape of a waterfowl's head is attached to the upper front side of the cover 22 and is fixed to a vertical rotating shaft 23 so as to be rotatable in left and right directions. The lower end of the rotating shaft 3 is covered by a cover 22.
It penetrates almost perpendicularly to reach the lower part, and at its lower end there is a gap between the joint part of the cover 22 and the floating body 21 (although it is not shown in the figure, there is a notch on the front side of the floating body 21 shown in FIG. 1). The lever 24 whose tip 24a protrudes outward is fixed via the portion 21a which becomes a gap between the cover 22 and the floating body 21 when they are joined. With such a configuration, the lever 24
is rotatable together with the neck member 22a, and is given a rotational return force by a spring 25 in the direction in which its tip protrudes most outward.

Further, as the power source 3, a battery (not shown) housed in the battery box 21b of the floating body 21 is used.
It uses a motor that is powered by electricity. One power shaft 32 is taken out from the power source 3 through a power transmission gear mechanism 31 shown as a black box and projects outward from the rear of the floating body 21, and an underwater moving means 32 is attached to the rear end of the floating body 21. A screw 41 illustrated as is fixed. Further, the power transmission gear mechanism 31
A pinion 34 is fixed to another power shaft 33 (this power shaft rotates relatively slowly) that is taken out through the shaft. This pinion 34
A crown gear 36 fixed to a vertical rotating shaft 35 provided upright within the floating body 21 meshes with the crown gear 36, and a gear 37 for rotating the rotating member 5 is fixed to the upper end of the rotating shaft 35.

Further, the moving means 4 includes underwater moving means and land moving means. The underwater transportation means has already been described as the screw 41, so a redundant explanation thereof will be avoided here. On the other hand, the land transportation means is composed of driving wheels 42, 43 (FIG. 3) attached to the lower part of the main body 2 and a driven wheel 44.
3 is the power transmission gear mechanism 3 from the power source 3;
1 (illustration of the power transmission relationship is omitted), and the driven wheel 44 is free to rotate.
Further, a rubber ring 42a for preventing slipping is fitted to one of the drive wheels 42, and the other drive wheel 43
Does not come with anti-slip material.

Further, as shown in FIG. 1, the rotating member 5 is made in the shape of an annular plate, and is fitted onto an annular stepped portion 21c at the upper end of the floating body 21, which is the joint between the floating body 21 and the cover 22. has been done. Internal teeth 5a that mesh with the gear 37 are formed on the inner peripheral edge of the rotating member 5 over the entire circumference, and a belt-shaped eccentric frame 5b is provided on the lower surface of the outside thereof to protrude over the entire circumference. There is. The eccentric frame 5b has an annular band shape or an elliptical band shape, and is arranged so that its center is eccentric from the center of the rotating member 5, and the tip of the lever 24 is in sliding contact with the inner peripheral surface of the eccentric frame 5b. There is.

When the gear 37 is rotated counterclockwise from the power source 3 via the power transmission gear mechanism 31, pinion 34, crown gear 36, and vertical rotation shaft 35, the rotating member meshes with the gear 37. 5 is also rotated in the same direction. With this rotation, the sliding contact portion of the eccentric frame 5b with the tip of the rotating lever 24 changes moment by moment, and the portion 5ba of the eccentric frame 5b that is longer from the center of the rotating member 5 (FIG. 4)
When the tip 24a of the rotary lever 24 comes into sliding contact with the main body 2, the tip 24a of the rotary lever 24 becomes in a state where it protrudes more from the main body 2, that is, the state where it is rotated back by the spring 25 (shown by the solid line in FIG. 4), while the eccentric frame 5b When the portion 5bb (FIG. 4) having a short distance from the center of the rotating member 5 comes into sliding contact, the tip 24a of the rotating lever 24 protrudes shorter from the main body 2, that is, against the force of the spring 25, from above. Turned counterclockwise when viewed (4th
It is shown by a two-dot chain line in the figure. ), so that
The rotation lever 24 is rotated left and right, which in turn causes the neck member 22a to be rotated left and right.

In addition, a battery box 21b is provided at the bottom of the floating body 21.
A lid 26 and a switch 27 for stopping the power source 3 are attached.

Next, the handling and operation of the amphibious mobile toy 1 of the embodiment configured as described above will be explained.

First, when the power source 3 is activated by operating the switch 27, the screw 41 and the driving wheel 42,
43 rotates, the rotating member 5 slowly rotates counterclockwise when looking down from above, and the neck member 2
2a rotates left and right.

When the amphibious mobile toy 1 is floated on water in a container (not shown) such as a tub in this operating state, it is propelled by the screw 41 while swinging the neck portion (neck member 22a) from side to side. (forward)
do. When the outer circumferential edge of the rotating member 5 comes into contact with the inner circumferential wall surface (obstruction) of the tub, the main body 2 looks down from above and changes direction to the right, avoiding the obstacle and moving further. becomes.

On the other hand, when the amphibious mobile toy 1 is raised on land in the same operating state, the drive wheels 42, 4
3 and the driven wheels 44 are in contact with the ground, while swinging the head (neck member 22a) left and right, the driving wheels 42, 4
3 to move forward. And the rotating member 5
When the outer peripheral edge of the main body 2 comes into contact with an obstacle such as a wall of a room (not shown), the main body 2 looks down from above and changes direction to the right (at this time, one of the drive wheels 43 (the other drive wheel 42 does not slip), and the vehicle moves forward avoiding the obstacle.

In the above embodiment, the degree to which the main body 2 floats on water is not mentioned, but it includes both cases where the main body 2 floats with the upper part exposed above the water and cases where the upper part of the main body 2 floats without being exposed.
Further, although a motor is illustrated as an example of the power source 3, the present invention is not limited to this, and a spring type or other power source may be used. Further, although the screw 41 and the drive wheels 42, 43 are illustrated as the moving means 4, the present invention is not limited thereto, and includes moving means such as gas injection and walking motion.

(Effect of the invention) The amphibious mobile toy according to the embodiment of this invention is
On land, the vehicle moves in a straight line with its drive wheels, while the rotating member rotates, swinging the neck member from side to side, and when it hits an obstacle, the rotating member slides into contact, changing the direction of movement and moving further straight, while on the water, the vehicle moves straight. While moving straight with the screw, the rotating member rotates, causing the neck member to swing left and right as it moves, and when it hits an obstacle, the rotating member slides into contact, changes the direction of movement, and moves further straight, so it does not simply move straight. It is an interesting toy that automatically changes direction when it hits an obstacle and moves further.
