Description

[Detailed Description of the Invention] The present invention relates to an animal vehicle used in amusement parks and the like.

In conventional animal vehicles of this type, the legs do not move, but the wheels are rotated by a motor.

However, this kind of movement did not resemble that of a real animal, so it lacked interest.

An object of the present invention is to provide an animal vehicle whose legs move in a manner similar to that of an actual animal.

The animal vehicle of the present invention includes a body frame, a front wheel attached to the center of the front part of the body frame, and a first rear wheel and a second rear wheel attached to the left and right sides of the rear part of the body frame, respectively. A leg frame whose central portion is pivotally supported by the vehicle body frame between the first and second rear wheels so that the left and right sides can move up and down; The supported first and second rear legs, a road kicking member provided on the lower surface of the tips of the first and second rear legs, and a vertically standing member adjacent to the center portion of the leg frame. a rotating shaft that is mounted on the rotating shaft and is adapted to be moved by a motor; a main cam that has a small diameter arc portion and a large diameter arc portion and is supported substantially horizontally on the rotating shaft and is rotationally driven; and an outer periphery of the main cam. Corresponding to the left and right portions of the leg frame, respective intermediate portions are supported pivotably, and first and second rollers that rotate in contact with the outer periphery of the main cam are supported pivotably on the upper part of each, and the lower ends of each are pivotably supported. first and second elevation control cams that are in contact with each other so as to alternately push the vehicle body frame; a first end that is commonly pivotally supported near the boundary between the large-diameter arc portion and the small-diameter arc portion; a second connecting rod; and a first rotating arm having one end pivotally supported at the other end of the first connecting rod and the other end integrally connected to the base of the first rear leg. a second rotating arm having one end pivotally supported at the other end of the second connecting rod and the other end integrally connected to the base of the second rear leg; and a handle connected to the front wheel. It is characterized by having the following.

Embodiments of the present invention will be described in detail below with reference to the drawings. In this embodiment, the present invention is applied to a turtle. This animal vehicle has a body frame 1, on which one front wheel 2 and first and second rear wheels 3, 4 are rotatably supported. At the rear of the vehicle body frame 1, the center portion of a leg frame 5, which is substantially V-shaped and whose both ends swing up and down, is swingably supported by a shaft 6. At both ends of the leg frame 5, first and second rear legs 7, 8 are supported by vertical shafts 9, 10 so as to be movable back and forth. First and second rubber pads 11 and 12 are fixed to the lower surface of the tip of each of the rear legs 7 and 8 as road kicking members, and first and second rubber pads 11 and 12 are fixed to the upper surface of the tip of each of the rear legs 7 and 8.
The legs 13 and 14 are fixedly installed.

A motor 15 is fixed to the vehicle body frame 1 in a vertical axis arrangement, and a rotating shaft 16 protrudes from the upper surface of the motor 15.
A main cam 17 is fixedly attached to the main cam 17 and is rotatably driven by the rotation of the rotating shaft 16. The main cam 17 includes a small diameter arc portion 17A and a large diameter arc portion 17B. The leg frame 5 has first and second cams at positions corresponding to the outer periphery of the main cam 17.
The middle part of the elevation control cams 18, 19 is the shaft 20, 2.
1, each is rotatably supported. At the upper ends of these first and second elevation control cams 18 and 19, a first cam that rotates in contact with the outer periphery of the main cam 17 is provided.
Second rollers 22 and 23 are rotatably supported. The lower ends of the first and second elevation control cams 18 and 19 are in contact with the upper surface of the vehicle body frame 1. The main cam 17 also serves as a crank, and one end of each of first and second connecting rods 25 and 26 is rotatably supported by a crank pin 27 on its upper surface. The crack pin 27 has a small diameter arc portion 17A
It is provided near the boundary between the large-diameter arc portion 17B and the large-diameter arc portion 17B. First connecting rod 25
One end of the first rotating arm 28 is connected to a shaft 29 at the other end.
are rotatably connected. The other end of the first rotating arm 28 is integrally connected to the base of the first rear leg 7 in a substantially horizontal direction at right angles.
The other end of the second connecting rod 26 has a second
One end of a rotating arm 30 is rotatably connected to the shaft 31, and the other end of the second rotating arm 30 is integrally connected to the base of the second rear leg 8 in a substantially horizontal direction at right angles to the base. has been done.

The vehicle body frame 1 includes first and second front legs 32, 3.
3 is supported by shafts 34 and 35 so as to be freely rotatable back and forth. These front legs 32, 33 are provided at a height that does not touch the road surface 24, and are designed to simply move back and forth. First and second front legs 36 and 37 are fixed to the tips of the first and second front legs 32 and 33, respectively. When the first rear leg 7 comes forward, the first front leg 32
The first front leg 32 is attached to the wire 3 so that the
8, and a middle portion of the wire 38 is guided by a plurality of rollers 39. In this way, when the first hind leg 7 comes forward, the second hind leg 8 descends backward, and the force of the second hind leg 8 descending backward is applied to the first front leg 32 by the wire 38. transmitted,
It will descend back onto the first front leg 32. The first front leg 32 is biased forward by a first tension spring 40 so as to come forward when the wire 38 becomes slack. When the second hind leg 8 descends backward, the first front leg 3
The second front leg 33 is connected to the first rear leg 7 by a wire 41 so that the second front leg 3 protrudes forward, and the middle portion of the wire 41 is guided by a plurality of rollers 42. The second front leg 33 is urged forward by a tension spring 43. As a result, when the second rear leg 8 descends backward, the first rear leg 7 moves forward, causing the wire 41 to become slack, and the second tension spring 43 biasing the second front leg 33 forward. The force of the second front leg 33
is projected to the front.

A handle 44 is connected to the front wheel 2 so that the direction of travel can be changed. A storage battery 45 is mounted on the vehicle body frame 1 to supply power to the motor 15. Further, a turtle-shaped cover (not shown) is placed over the vehicle body frame 1, and a seat-type driver's seat is provided in a part of this cover.

Next, the walking motion of this animal vehicle will be explained.

When the main cam 17 is not in contact with either the first or second rollers 22, 23 as shown in FIGS. 2 and 3, the main cam 17 is The rear wheels 3 and 4 of the second rear legs 7 and 8 are both in contact with the ground, and the pads 11 and 12 of the first and second rear legs 7 and 8 are lifted off the ground.
is lowered to the rear, and the second hind leg 8 is in a state of protruding forward.

From this state, the main cam 1 is
7 is rotated in the direction of the arrow in FIGS. 2 and 4, the main cam 17 is rotated as shown in FIGS. 4 and 5.
The large-diameter arcuate portion 17B pushes the first roller 22, the first elevation control cam 18 is forcibly rotated about the shaft 20, and its lower end presses against the upper surface of the vehicle body frame 1. Then, due to the reaction force at that time, the leg frame 5 is forcibly rotated in a direction in which the first rear leg 7 side rises with respect to the vehicle body frame 1, and the second rear leg 8 is lowered and the pad 12 is grounded. stop,
Furthermore, as the leg frame 5 is rotated in the tilting direction, the vehicle body frame 1 is tilted and the second rear wheel 4 is lifted up.

On the other hand, due to the rotation of the main cam 17, the first
The rear leg 7 is rotated in the forward direction, and the second rear leg 8 is rotated in the backward downward direction. At this time, the second rear leg 8 is in contact with the ground as described above, and the second rear wheel 4 is in a floating state, so that the reaction force of the rearward movement of the second rear leg 8 is applied to the vehicle body frame. 1 as a force in the forward direction, which causes the animal vehicle to move forward.

Similarly, when the main cam 17 rotates and the large-diameter arc portion 17B presses the second roller 23, the first rear wheel 3 lifts up and the first rear leg 7 moves backward from the forward position. It is rotated in the downward direction to move the animal vehicle forward.

The vehicle moves forward by repeating these actions.

The shape of the vehicle is not limited to a turtle, but may be any other shape such as a crocodile or a beetle.

Furthermore, since the front legs 32 and 33 do not have the function of moving the vehicle forward, they may be used without the operating mechanism.

As explained above, the animal vehicle according to the present invention moves forward by the forward and backward movement of its legs, so unlike conventional animal vehicles of this type, it can approximate the real movement of animals and increase visual interest. . Further, when the rear leg on one side is kicking the road surface, the leg on the other side is away from the road surface, so there is an advantage that the leg that is not kicking the road surface does not get in the way of the vehicle's progress. Furthermore, since the passengers are subject to side-to-side sway,
You can create the feeling of riding an animal.
