Game toy device using remote-controlled traveling toy, remote-controlled traveling toy, and game board
The present invention provides a play toy system using a remote-controlled traveling toy, which enables the remote-controlled traveling toy to make a movement that is more unexpected than before, for play. The remote-controlled traveling toy 1 includes one front wheel 5 and two rear wheels 7 and 9. The traveling toy is remotely controlled by remote control signals and is so constructed as to travel on a traveling surface of a play board. The diameter sizes of the two rear wheels 7 and 9 are different. With one front wheel 5 and two rear wheels 7, 9 having a different diameter, the remote-controlled traveling toy 1 can move most unexpectedly that anyone has ever experienced, according to the state of the traveling surface of the play board.
1. A play toy system using a remote-controlled traveling toy, comprising:
a remote control device for outputting a remote control signal;
a remote-controlled traveling three-wheeled toy having only one front wheel, only two rear wheels, and an electric motor remote controlled by said remote control signal; and
a play board having a travel surface on which said remote-controlled traveling toy travels;
wherein diameter sizes of said two rear wheels of said remote-controlled traveling toy are different;
wherein said play board is shaped so that said travel surface is continuous in a circumferential direction thereof and a height thereof from an installation surface is decreasing toward a central portion thereof; and
in said central portion thereof is formed a concave section with a size capable of fully receiving said front wheel and/or said rear wheels and a depth allowing said remote-controlled traveling toy to get out of there by itself.
2. The play toy system using a remote-controlled traveling toy according to claim 1 , wherein an angle between an inner periphery surface of said concave section and said installation surface is set to an angle range of 93±1°.
3. The play toy system using a remote-controlled traveling toy according to claim 1 , wherein a main portion of said travel surface comprises a first inclined surface adjacent to said concave section and having a first radius of curvature and a second inclined surface continuous with an outside of said first inclined surface and having a second radius of curvature close to infinity; and
an angle of said second inclined surface from said installation surface is set in the angle range of 32.2° to 42.2°.
4. The play toy system using a remote-controlled traveling toy according to claim 1 , wherein said travel surface comprises a first inclined surface adjacent to said concave section and having a first radius of curvature, a second inclined surface continuous with an outside of said first inclined surface and having a second radius of curvature close to infinity, a third inclined surface continuous with an outside of said second inclined surface and having a third radius of curvature smaller than the first radius of curvature, and a fourth inclined surface continuous with an outside of said third inclined surface and having a fourth radius of curvature smaller than the third radius of curvature;
width sizes of said first, second, third, and fourth inclined surfaces become smaller in an order of said second inclined surface, said first inclined surface, said third inclined surface, and said fourth inclined surface; and
an angle of said second inclined surface from said installation surface is set in the angle range of 32.2° to 42.2°.
5. The play toy system using a remote-controlled traveling toy according to claim 4 , wherein an angle between said third inclined surface and said installation surface is set in an angle range of 48±2°; and
an angle between said fourth inclined surface and said installation surface is set in an angle range of 89±1°.
6. The play toy system using a remote-controlled traveling toy according to claim 5 , wherein a substantially horizontal surface is provided outside said fourth inclined surface.
7. A play board having a travel surface on which a remote-controlled traveling three-wheeled toy travels, wherein said toy has only one front wheel, only two rear wheels, and an electric motor remotely controlled by a remote control signal,
said travel surface is shaped to be continuous in a circumferential direction thereof and have a height thereof from an installation surface is decreasing toward a central portion thereof; and
in said central portion thereof is formed a concave section with a size capable of fully receiving said front wheel and/or said rear wheels and a depth allowing said remote-controlled traveling toy to get out of there by itself.
8. The play toy system using a remote-controlled traveling toy according to claim 2 , wherein a main portion of said travel surface comprises a first inclined surface adjacent to said concave section and having a first radius of curvature and a second inclined surface continuous with an outside of said first inclined surface and having a second radius of curvature close to infinity; and
an angle of said second inclined surface from said installation surface is set in the angle range of 32.2° to 42.20°.
9. The play toy system using a remote-controlled traveling toy according to claim 2 , wherein said travel surface comprises a first inclined surface adjacent to said concave section and having a first radius of curvature, a second inclined surface continuous with an outside of said first inclined surface and having a second radius of curvature close to infinity, a third inclined surface continuous with an outside of said second inclined surface and having a third radius of curvature smaller than the first radius of curvature, and a fourth inclined surface continuous with an outside of said third inclined surface and having a fourth radius of curvature smaller than the third radius of curvature;
width sizes of said first, second, third, and fourth inclined surfaces become smaller in an order of said second inclined surface, said first inclined surface, said third inclined surface, and said fourth inclined surface; and
an angle of said second inclined surface from said installation surface is set in the angle range of 32.2° to 42.2°.
