Abstract

A toy dart having an elongate dart body of a foam material in a substantially cylindrical shape extending from a head end to a tail end in a first, longitudinal direction, an outer surface of the substantially cylindrical shape having a first ridge proximate the head end; a second ridge proximate the tail end; and one or more recessed areas disposed between the first ridge and the second ridge, where the elongate dart body has a first outer diameter at the first ridge and the second ridge that is larger than a second outer diameter at the one or more recessed areas; and a deformable dart cap affixed to the head end of the elongate dart body.

Claims (24)

1. A toy dart, comprising:

an elongate dart body comprising a foam material in a substantially cylindrical shape extending from a head end to a tail end in a first, longitudinal direction, an outer surface of the substantially cylindrical shape comprising:

(1) a first ridge proximate the head end;

(2) a second ridge proximate the tail end; and

(3) one or more recessed areas disposed between the first ridge and the second ridge,

wherein the elongate dart body has a first outer diameter at the first ridge and the second ridge that is larger than a second outer diameter at the one or more recessed areas; 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.

2. The toy dart of claim 1 , wherein the first outer diameter is approximately 12.9 mm.

3. The toy dart of claim 1 , wherein the second outer diameter is approximately 12.5 mm to 12.8 mm.

4. The toy dart of claim 3 , wherein the second outer diameter is approximately 12.7 mm.

5. The toy dart of claim 1 , wherein the first and second ridges form respective first and second rings around the outer surface of the substantially cylindrical shape in relation to the one or more recessed areas.

6. The toy dart of claim 1 , wherein the first ridge and the second ridge each extend approximately between 3.5 mm and 6 mm in the first, longitudinal direction.

7. The toy dart of claim 6 , wherein at least one of the one or more recessed areas extends approximately between 16 mm and 18.5 mm in the first, longitudinal direction.

8. The toy dart of claim 7 , wherein the substantially cylindrical shape of the elongate dart body is approximately between 30 mm and 65 mm in length in the first, longitudinal direction.

9. The toy dart of claim 1 , wherein a front edge the first ridge is 3.5 mm or less from the head end.

10. The toy dart of claim 9 , wherein the front edge of the first ridge is aligned with the head end.

11. The toy dart of claim 1 , wherein a rear edge of the second ridge is 3.5 mm or less from the tail end.

12. The toy dart of claim 11 , wherein the rear edge of the second ridge is aligned with the tail end.

13. The toy dart of claim 1 , wherein the one or more recessed areas extend in the first, longitudinal direction to form approximately 55-80% of a length of the elongate dart body.

14. The toy dart of claim 13 , wherein the one or more recessed areas comprises a plurality of the recessed areas that extend in the first, longitudinal direction to collectively form approximately 75-80% of the length of the elongate dart body.

15. The toy dart of claim 14 , further comprising one or more additional ridges a predetermined distance from one or more of the first ridge and the second ridge across respective one or more of the plurality of the recessed areas in the first, longitudinal direction, wherein the first ridge, the second ridge, and the one or more additional ridges extend in the first, longitudinal direction to collectively form approximately 20-25% of the length of the elongate dart body.

16. The toy dart of claim 13 , wherein the one or more recessed areas extend in the first, longitudinal direction to form approximately 55-70% of the length of the elongate dart body.

17. The toy dart of claim 16 , wherein the first ridge and the second ridge extend in the first, longitudinal direction to collectively form approximately 30-45% of the length of the elongate dart body.

18. The toy dart of claim 1 , wherein the deformable dart cap comprises two cavities on opposing sides of the outer surface of the deformable dart cap.
