Abstract
The invention disclosed is directed to a line-drawing toy including a base, a wheel rotatably joined to the base that rotates under friction with a contact surface, a leading support joined to the base and spaced apart from the wheel, a pen part operatively joined to the base between the leading support and the wheel, the pen part including at least one pen tip for drawing a line on a contact surface, and a gear mechanism operatively joined to the pen part and the wheel, the gear mechanism having means for converting the rotary motion of the wheel into a predetermined pattern of movement for the pen tips.
Claims6
A line-drawing toy comprising:
- a base;
- a wheel rotatably joined to the base that rotates under friction with a contact surface;
- a leading support joined to the base and spaced apart from the wheel, the leading support for supporting the base above a contact surface;
- a pen part operatively joined to the base between the leading support and the wheel, the pen part including at least one pen tip for drawing a line on a contact surface;
- and
- a gear mechanism operatively joined to the pen part and the wheel, the gear mechanism having an intermeshing gear assembly for converting the rotary motion of the wheel into a predetermined pattern of the pen tip.

- a leading support joined to the base and spaced apart from the wheel, the leading support for supporting the base above a contact surface;
- a pen part operatively joined to the base between the leading support and the wheel, the pen part including at least one pen tip for drawing a line on a contact surface;
- and
- a gear mechanism operatively joined to the pen part and the wheel, the gear mechanism comprising:
- a crown gear disposed on the wheel;
- a gear;
- means for meshing the crown gear and the gear;
- and
- a shaft joined to the gear for rotation therewith, and having means for rotating the pen part.

- a pen part operatively joined to the base between the leading support and the wheel, the pen part including at least one pen tip for drawing a line on a contact surface;
- and
- a gear mechanism operatively joined to the pen part and the wheel, the gear mechanism having means for converting the rotary motion of the wheel into a reciprocal rotary motion in the pen part, said means comprising:
- a gear for rotating in one direction;
- a lever arm having a first end and a second end, the first end eccentrically joined to the gear;
- and
- a sector gear joined to the second end of the lever arm.
