Abstract

The technology described herein relates to a spiral art device that allows a user to create and recreate spiral art designs with chalk, and in particular with sidewalk chalk. The spiral art device in accordance with aspects herein comprises one or more stencil pieces and a motor piece. The motor piece is configured to move the stencil piece a predetermined distance around the motor piece, as many times as desired to form the spiral art design. The stencil piece is configured to have multiple securing points that allow the stencil piece to be secured to the motor piece at different angles, further allowing the user to add additional variations to their spiral art design. Design variations may be exponentially multiplied when multiple stencils having differently shaped traceable margins are provided with the spiral art device in accordance with aspects herein.

First claim

The invention claimed is:

1. A spiral art device comprising:
a removable stencil piece comprising:
(1) a traceable opening; and
(2) at least two locking openings; and

a motor piece comprising:
(1) a base member having a first central elongated stem portion;
(2) a template ring member comprising a template arm on an exterior surface, the template arm having at least two stencil locking pins;
(3) a first ring member having a first plurality of cams evenly distributed around a first circumference of the first ring member, wherein the first plurality of cams point in a first direction;
(4) a second ring member having a second plurality of cams evenly distributed around a second circumference of the second ring member, wherein the second plurality of cams point in a second direction that is opposite to the first direction;
(5) a spring member;
(6) a plunger cap member; and
(7) a locking cap member.

2. The spiral art device of claim 1 , wherein the second ring member is an integral part of the plunger cap member.

3. The spiral art device of claim 1 , wherein the traceable opening of the removable stencil piece comprises one of a geometric shape, an organic shape, or an animal shape.

4. The spiral art device of claim 1 , wherein a perimeter of the removable stencil piece comprises one or more of a curved edge, a straight edge, a jagged edge, and a wavy edge.

5. The spiral art device of claim 1 , wherein the removable stencil piece's longest dimension measures between 10 cm and 50 cm in length, and wherein the removable stencil piece's widest dimension measures between 3 cm and 10 cm in width.

6. The spiral art device of claim 1 , wherein the base member comprises one or more gripping/cushioning feet on a first surface that is configured to be a ground-contacting surface.

7. The spiral art device of claim 6 , wherein the base member comprises alternating reference symbols on a second surface that is configured to face a user when the spiral art device is in use.

8. The spiral art device of claim 1 , wherein the template ring member further comprises a plurality of pin elements on an interior surface of the template ring member, wherein the plurality of pin elements are configured to alternately engage with the first plurality of cams of the first ring member and the second plurality of cams of the second ring member.

9. The spiral art device of claim 1 , wherein the spring member is comprised of one of a metal, a plastic, a coated metal, and a thermoplastic coated metal.

10. The spiral art device of claim 1 , wherein the first central elongated stem portion of the base member comprises an opening, and wherein the plunger cap member comprises a second central elongated stem portion that is configured to slide into the opening of the first central elongated stem portion.

11. A spiral art device system kit comprising:
a plurality of colored chalk pieces;
a plurality of interchangeable stencil pieces, each interchangeable stencil piece comprising:
(1) a traceable opening;
(2) a traceable edge; and
(3) a plurality of locking openings; and

a motor piece comprising:
(1) a base member having a first central elongated stem portion, the first central elongated stem portion comprising an opening;
(2) a template ring member comprising an interior surface and an exterior surface, the interior surface comprising a first plurality of pins, and the exterior surface comprising a template arm with a second plurality of pins;
(3) a cam ring member comprising a first plurality of cams evenly distributed around a first circumference of the first ring member, wherein the first plurality of cams point in a first direction;
(4) a plunger cap member comprising a first surface and a second surface, the second surface of the plunger cap member comprising a ring portion having a second plurality of cams protruding from the second surface of the plunger portion in a second direction that is opposite to the first direction, wherein the second plurality of cams are evenly distributed around the circumference of the ring portion, and a second central elongated stem portion fitted into the opening of the first central elongated stem portion; and
(5) a spring member.

12. The spiral art device system kit of claim 11 , wherein the first surface of the plunger cap member is a user-contacting surface when the spiral art device is in use.

13. The spiral art device system kit of claim 12 , wherein the template ring member is configured to rotate a first distance when the first plurality of pins are engaged with the first plurality of cams, and rotate a second distance when the first plurality of pins are engaged with the second plurality of cams.

14. The spiral art device system kit of claim 13 , wherein the second plurality of pins are configured to engage with two or more of the plurality of locking openings of a first interchangeable stencil piece in the plurality of interchangeable stencil pieces.

15. The spiral art device system kit of claim 14 , wherein the first interchangeable stencil piece may be engaged with the motor piece at different angles.

16. The spiral art device system kit of claim 11 , wherein the plurality of locking openings are hexagonally shaped.

17. The spiral art device system kit of claim 11 , wherein the second plurality of pins have a circular cross-section.

18. The spiral art device system kit of claim 11 , wherein the first plurality of cams and the second plurality of cams face each other, and wherein the first plurality of cams are not aligned with the second plurality of cams.

19. The spiral art device system kit of claim 11 , wherein when in a rest state, the spring member is in an expanded state and the first plurality of pins are engaged with the first plurality of cams, and wherein when in the spring is in a compressed state, the first plurality of pins become engaged with the second plurality of cams, causing the template ring to rotate.

20. A motor piece for a spiral art device comprising:
a base member having a first central elongated stem portion, the first central elongated stem portion comprising an opening;
a template ring member comprising an interior surface and an exterior surface, the interior surface comprising a first plurality of pins, and the exterior surface comprising a template arm with a second plurality of pins;
a cam ring member comprising a first plurality of cams evenly distributed around a first circumference of the first ring member, wherein the first plurality of cams point in a first direction;
a plunger cap member comprising a first surface and a second surface, the second surface of the plunger cap member comprising a ring portion having a second plurality of cams protruding from the second surface of the plunger portion in a second direction that is opposite to the first direction, wherein the second plurality of cams are evenly distributed around the circumference of the ring portion, and a second central elongated stem portion fitted into the opening of the first central elongated stem portion; and
