Description

[Detailed description of the invention] This invention relates to a traveling toy, in particular, the toy moves in a meandering manner by rotating the wheels, and at the same time swings the head back and forth, as well as the up and down movement of both arms and the up and down movement of the tail. The purpose of the present invention is to provide a running drive toy that enables four different movements by the same drive mechanism, thereby dramatically increasing interest in this type of drive toy.

The present invention will be described based on drawings showing embodiments thereof.

Reference numeral 1 denotes a toy body which is made of metal, synthetic resin, or other appropriate material into the shape of an animal or other arbitrary shape, and includes a substantially hemispherical head 2, a body body 3, and a body body 3.
Both arms 4a and 4b are provided at symmetrical positions,
A tail 5 protruding from the lower back of the body body 3, a wheel 6 protruding from the bottom of the body body 3,
It consists of 7.

Reference numeral 8 denotes a drive case that accommodates the drive mechanism A, which is formed into a box-shaped frame with a rectangular cross section with both ends open. Mounting parts 9 provided at both ends of the upper surface of the drive case are bridged and screwed to the upper edge of the body main body 3. It is housed inside.

The body main body 3 is divided into two parts in the longitudinal direction at the center of both side faces, formed approximately symmetrically in the front and back, and connected and fixed together by a bridge of the mounting part 9 of the drive case 8.

The drive mechanism A in the drive case 8 has a mainspring 10 and a gear 11 that are pivotally mounted, and both ends thereof protrude outside the drive case 8, and arms 4a and 4b are respectively supported.
At one end thereof, a spring winding screw 12 is connected, and a rotary drive shaft 13 is mounted on the drive case 8, and a rotary drive shaft 13 is mounted on the drive case 8 in the vertical direction of the rotary drive shaft 13, and is connected to the gear 11 in the vertical direction. It consists of rotating shafts 14 and 15, each of which has gears 16 and 17 that are rotatably engaged with each other.

A part of the root of the arm 4a is protruded and becomes a swinging rod 18 that is a follower of the cam, and the swinging rod 18 is connected to a triangular cam 19 that is pivoted on a rotating shaft 16 that projects outward from the drive case 8. The triangular cams 19 are provided so as to be able to swing in contact with each other by rotation of the triangular cam 19.

A disc cam 21 is protruded at an eccentric position on the other surface of the rotating disc 20, from which the triangular cam 19 is protruded. A head swinging rod 22, which is a follower hanging from a position eccentric from the center point of the inner surface of the substantially hemispherical head 2, comes into contact with the cam 21, and the rotation of the cam 21 causes the head to swing. The rod 22 is moved up and down to swing the head back and forth.

Two support rods 23 are provided protruding from the inner surface of the head 2, and the support rods 23 pivot from above on both ends of a support rod 24 that is inserted and protruded toward the upper end of the drive case 8. The head 2 is supported so as to be able to move back and forth as the head swinging rod 22 moves up and down.

A part of the root of the arm 4b is protrudingly provided and serves as a follower rocking plate 25 which is divided into two roughly wing-shaped parts, and the upper part of the rocking plate 25 is the end of the rotating shaft 16 that projects outward from the drive case 8. The arm 4b is in contact with a disc cam 26 which is pivotally attached to the arm 4b, and the rotation of the disc cam 26 causes the arm 4b to swing up and down.

As shown in FIG. 8, the root end 5a of the tail 5 is in contact with the lower part of the rocking plate 25, and a portion of the tail 5 in the root direction is pivotally supported by a pin 27 to be able to swing against the inner surface of the main body 3. Due to the vertical movement of the swing plate 25, the swing plate 25
The tail 5 in contact with is moved up and down.

The rotating shaft 17 has both ends protruding outward from the drive case 8, and wheels 6 and 7 are respectively pivotally attached to both ends of the rotating shaft 17.

As shown in FIGS. 5 and 6, the wheels 6 and 7 are formed into substantially elliptical deformed discs with small circular portions 6a and 7a and large circular portions 6b and 7b having different inner diameters, respectively.
Moreover, the small circular portion 6a of the wheels 6 and 7 that are placed opposite each other
The small circular portion 7a, the large circular portion 6b, and the large circular portion 7b are provided in substantially opposite positions.

That is, when the small circular portion 6a of the wheel 6 is in contact with the ground,
The wheels 7 are arranged so that the large circular part 7b is in contact with the ground, and the small circular part and the large circular part are opposite to each other, and as the wheels 6 and 7 rotate, their running distances are different from each other. It is formed so that it can travel in a meandering manner as if swinging.

A mop-shaped rod 28 for cleaning is inserted into the upper end of the arm 4a, as shown in FIG. Since the rod 28 is inserted into the arm 4a with the center of gravity shifted toward the rear 28a, a force that always urges the arm 4a backward is not exerted, so the swing rod 18 protruding from the root of the arm 4a is attached to the cam. 1
9 and is held in constant contact with it from below.

To explain the operation of the present invention, when the mainspring 10 is wound by the mainspring winding screw 12, the winding force of the mainspring 10 becomes a driving force, and when the rotary drive shaft 13 is rotated, the gear 11,
Rotating shafts 16 and 17 are rotated via 14 and 15.

The wheels 6 and 7 rotate due to the rotation of the rotating shaft 17, and the toy main body 1 meanders.

On the other hand, both arms 4a and 4b are connected to the cam 19 of the rotating shaft 16,
The head 2 swings up and down by the rotation of the cam 26, and the head 2 swings back and forth by the cam 21.

Furthermore, the tail 5 moves up and down and is swung by a swiveling plate 25 protruding from the root of the arm 4b which is swung by a cam 26.

In this way, one drive mechanism A using a mainspring as a drive source performs four operations at the same time.

Although the present invention uses a mainspring as a driving source, it is of course possible to use an electric motor or other driving source instead.

The present invention is constructed as described above, so it can run in a meandering manner by rotating the wheels, while at the same time swinging its head back and forth as if nodding at each other, swinging its arms up and down, and moving its tail up and down. Because the toy performs two actions at the same time, the movement of the toy itself has a great deal of variation and character, which has the effect of dramatically increasing interest and enjoyment in the toy without getting boring.

Because a single drive mechanism performs four different movements at the same time, although the movement is extremely complex, its structure is relatively simple, and it is easy to handle and operate at a low cost. There is an effect that it can be done.
