Abstract

A toy dart includes a deformable cap that safely impacts a target. The cap includes two layers of substantially parallel hollow passages that provide spaces that allow the cap to deform. The lower layer, having two hollow passages, is supported by exterior posts and an interior wall between the two hollow passages. The upper layer, having three hollow passages, is supported by exterior posts and interior walls that are laterally offset from the interior wall of the lower layer. The upper and lower layers are separated vertically by a substantially flat divider. Due to the difference in the number of hollow passages and interior walls in each layer, the upper layer is more rigid than the lower layer such that the lower layer of the cap deforms more than the upper layer of the cap upon initial impact with the target.

Claims

1. A toy dart, comprising:

an elongate dart body extending from a head end to a tail end in a first, longitudinal direction; and

a deformable dart cap affixed to the head end of the elongate dart body, the deformable dart cap having a top, a bottom that is affixed into the elongate dart body, and an outer surface extending from the top to the bottom of the deformable dart cap in the first, longitudinal direction;

wherein the outer surface of the deformable dart cap comprises two layers of hollow passages extending through the deformable dart cap in a second direction that is substantially orthogonal to the first, longitudinal direction of the elongate dart body, the hollow passages connecting respective openings on opposing sides of the outer surface of the deformable dart cap and being separated by interior walls that extend in the second direction, the two layers of hollow passages comprising;

(1) a lower layer, which abuts the bottom of the deformable dart cap, comprising at least a first lower layer hollow passage and a second lower layer passage, the first lower layer hollow passage and the second lower layer passage being separated by a lower layer interior boundary;

(2) an upper layer, above the lower layer opposite from the bottom of the deformable dart cap, comprising at least a central upper layer hollow passage defined by two upper layer interior walls, the central upper layer hollow passage being offset in position laterally from the first lower layer hollow passage and the second lower layer passage; and

(3) a substantially flat divider extending in the second direction and separating the upper and lower layers.

2. The toy dart of claim 1, wherein the first and second lower layer hollow passages are adjacent and substantially parallel to one another, and wherein the first and second lower layer hollow passages are separated from one another by an interior wall that provides the lower layer interior boundary therebetween.

3. The toy dart of claim 2, wherein the lower layer interior wall is positioned below and substantially midway between the two upper layer interior walls.

4. The toy dart of claim 1, wherein the first and second lower layer hollow passages are approximately equal in cross section.

5. The toy dart of claim 1, wherein the first and second lower layer hollow passages are further defined by two exterior posts, each extending longitudinally along the outer surface of the deformable cap and spaced approximately 180 degrees from one another.

6. The toy dart of claim 5, wherein the at least one lower layer interior wall is located substantially midway between the two exterior posts such that there is support for the lower layer radially at approximately every 90 degrees about a circumference of the deformable dart cap.

7. The toy dart of claim 1, wherein the upper layer further comprises at least two outer hollow passages on opposing sides of the central upper layer hollow passage.

8. The toy dart of claim 7, wherein the at least two outer hollow passages and the central upper layer hollow passage are substantially parallel to one another.

9. The toy dart of claim 7, wherein the at least two outer hollow passages are approximately equal in cross-section.

10. The toy dart of claim 7, wherein the at least two outer hollow passages and the central upper layer hollow passage are aligned with one another along the substantially flat divider.

11. The toy dart of claim 7, wherein the at least two outer hollow passages are further defined by two exterior posts, each extending longitudinally along the outer surface of the deformable cap and spaced approximately 180 degrees from one another.

12. The toy dart of claim 1, wherein the elongate dart body is substantially cylindrical.

13. The toy dart of claim 1, wherein the top of the deformable dart cap is curved.

14. The toy dart of claim 1, wherein the top of the deformable dart cap is substantially flat.

15. The toy dart of claim 1, wherein the elongate dart body comprises foam.

16. The toy dart of claim 1, wherein the lower layer interior wall is positioned in the lower layer to be laterally offset from the two upper layer interior walls in the upper layer such that the lower layer of the deformable dart cap is configured to compress more than the upper layer of the deformable dart cap upon initial impact of the top of the deformable dart cap on a person or on an object.

17. The toy dart of claim 1, wherein at least one of the first lower layer hollow passage, the second lower layer hollow passage, the central upper layer hollow passage, and the at least two outer hollow passages is substantially rectangular in cross-section.

18. The toy dart of claim 1, wherein at least two exterior posts extend in the first, longitudinal direction along opposite sides of the outer surface of the deformable dart cap in alignment between the lower layer and the upper layer, the at least two exterior posts being spaced away from the at least one lower layer interior wall and the at least two upper layer interior walls.
