Embodiments of the present invention are related to a toy dart assembly. More specifically, embodiments of the present invention provide a toy dart assembly which includes a dart and a net. Embodiments of the present invention further provide a method for engaging a net with a dart.
There are a number of assemblies available on the market which consist of a net assembly for stopping the movement of an airborne object (e.g., a golf ball), such as by way of example only: (a) the net assembly sold by Wilson Company that stops the movement of a golf ball after being hit; and (b) the hitting net assembly sold by Callaway for stopping the movement of a golf ball. However, none combine the features of a dart engaging a net assembly after being thrown against the net assembly.
Embodiments of the present invention provide a method for engaging a dart with a net. The method includes throwing a dart toward a net. When the dart hits the net after being thrown, the nose of the dart passes through an opening in the net. Subsequently, one or more strands of the net are lodged in a recess situated behind the nose of the dart.
Embodiments of the present invention also provide a recreational toy assembly having in combination a net and a dart. One or more strands of the net lodge in a recess behind the nose of the dart for coupling the dart to the net. The dart remains engaged to the net until the dart is removed from engagement with the net. For disengaging the dart from the net, the strand(s) is/are removed from the recess such that the nose of the dart may be passed out of opening in the net. The strands of the net provide the boundary or perimeter of the opening.
These provisions, together with the various ancillary provisions and features which will become apparent to those skilled in the art as the following description proceeds, are attained by the methods and assemblies of the present invention.
In the description herein, numerous specific details are provided, such as examples of components and/or methods, to provide a thorough understanding of the embodiments of the present invention. One skilled in the relevant art will recognize, however, that an embodiment of the invention may be practiced without one or more of the specific details, or with other apparatus, systems, assemblies, methods, components, materials, parts, and/or the like. In other instances, well-known structures, materials, or operations are not specifically shown or described in detail to avoid obscuring aspects of the embodiments of the present invention.
Referring in detail now to the drawings, wherein similar parts of the invention are identified by like reference numerals, there is seen in
Embodiments of the invention include a dart, generally illustrated as 30. In an embodiment of the invention, dart 30 is not the type of dart that consists of a pin-like point which sticks in a dart board after being thrown. As shown in
In one embodiment of the invention and as best illustrated in
In another embodiment of the invention and as best illustrated in
The diameter of circular surface 52 at its circumferential edge 52a is approximately equal to or approximately greater than distances of about A and B such that after conical-shaped member 38 passes through opening 26 subsequently after the dart 30 is thrown against the net 18, the circular surface 52 contacts or engages strands 22a-22a and/or strands 22b-22b to prevent dart 30 from traveling any further and to allow the strands to lodge within the recess 42 (see dashed lines 22b and 22a in
In a preferred embodiment of the invention, the diameter of the circular surface 52 is slightly greater than the largest circle or opening that can be formed by pulling or expanding the rectangular opening 26 into a circle or other opening. This assures that the dart 30 will not pass completely through the net.
The conical-shaped member 38 has an end 70 and a circular face 66 that couples to the coupling member 44. Circular face 66 has a circumferential edge 66a. The conical-shaped member 38 also includes an outside surface 74 that tapers from circular face 66 to the end 70. The diameter of circular face 66 at its circumferential edge 66a is approximately equal to or approximately greater than distances of about A and B. In a preferred embodiment of the invention, the diameter of circular face 66 is greater than distances of about A and B, but less than the largest circle or opening that can be formed by pulling or expanding the rectangular opening 26 into a circle or other opening. As the, the conical-shaped member 38 passes through rectangular opening 26, opening 26 is typically distorted or skewed into a general circular shape. After the strands 22a-22a and/or strands 22b-22b pass over the circumferential edge 66a of the circular face 66, they lodge in recess 42 and the perimeter of the opening 26 formed by the strands generally returns to its original shape (i.e., rectangular shape).
In another embodiment of the invention, strands 22a-22a and/or strands 22b-22b are elastic such as being capable of stretching. Thus, at least one pair of strands is capable of being stretched. The degree of elasticity of the strands depends on the material from which the strands are made. For this embodiment of the invention, the circumference of the surface 66 at its circumferential edge 66a (circular perimeter 66a) is approximately equal to or approximately greater than at least the distances of about A or B. Preferably the circumference of surface 66 at its circumferential edge 66a is greater than distances of about A and/or B, but is less than the circumference of surface 52 at its circumferential edge 52a (circular perimeter 52a). For this embodiment of the invention, when dart 30 is thrown toward the net 18, the conical-shaped member 38 enters into one of the openings 26. Because the surface 66 at its circumferential edge 66a is greater than distances A and B respectively, both pair of elastic strands 22a-22a and 22b-22b stretch to allow the conical-shaped member 38 of the dart 30 to pass through the opening 26, as best shown in

The probability of any opening in the net capturing the dart is also increased by increasing both the size of the tail fins and the length of the recess. As previously suggested, adding the weight member to the nose of the dart increases the inertia of the dart and causes any net strand contacting the nose of the dart to be pushed and/or stretched farther to the side. The weight member also moves the center-of-gravity of the dart towards the nose or conical section. The farther the center-of-gravity is moved forward, the lever arm of the rotational torque from the net strand becomes shorter which causes less rotation of the dart. If the center of gravity is past the net strand, the rotational torque is acting in the direction of restoring the dart to perpendicular. The larger-area tail fins create additional air drag against the rotation and keep the dart closer to perpendicular.
Increasing the length (in the direction of nose-to-tail) of the recess in the dart also increases the probability of any opening in the net capturing the dart. The length of the recess is indirectly proportional to the angle that the dart contacts the net. Stated alternatively, the farther off perpendicular (i.e., 90 degrees) the dart is when hitting or contacting the net, the greater the length of the recess needs to be, assuming that the circular face 66 is to pass completely through an opening in the net before movement of the dart is stopped by circular surface 52.
In preferred embodiments of the present invention, the dart is manufactured from soft foam (i.e., polyurethane or EVA foam having a density of about 3½ pounds per cubic foot). When the conical section of the dart consists of soft foam, the end of the conical section is typically not very durable and tends to be flexible. In a preferred embodiment of the invention, the end of the cone is preferably coated with a smooth flexible elastomeric or plastic material to prevent the point or end of the conical section from bending when striking the net and causing the dart to rotate sideways, or bounce off the net. The plastic material for coating the end of the cone may be any suitable plastic material, such as polypropylene, polyethylene, etc. The elastomeric or plastic material reduces the friction against the net strands as the dart enters the net, and makes the cone point more durable. The elastomeric material may be any suitable elastomeric material, such as by way of example only, flexible PVC, fluorosilicone (chloroprene), cast polyurethane, silicone, Neoprene® (chloroprene), and Viton® (fluorocarbon). Viton® and Neoprene® are registered trademarks of DuPont Performance Elastomers.
