The disclosure relates to a toy foam dart for use with a toy projectile launcher.
Toy foam darts, such as a dart having a foam body and a tip attached to one end of the dart body, are known and may be launched with a compatible toy dart launcher toward a person or an object. The tips of the toys darts are generally made of a rubber or other polymeric material having a higher weight than the foam that allows the dart to be launched from the launcher with greater speed and accuracy, but without injuring, or at least limiting the injury or discomfort felt by, the targeted person or object.
As consumers seek toy foam darts with greater accuracy and distance capabilities, this also raises a safety issue in order to avoid potential injury to users that are impacted by the toy foam projectiles since this is typically done by adding more weight to the tip. In the United States, ASTM F 963-16, The Standard Consumer Safety Specification for Toy Safety, is required to be met by all toy foam projectiles. This Standard specifies the requirements for a Kinetic Energy Density (KED) test with a maximum of 2500 J/m2 (Joules/meter square) for projectile toys. Accordingly, improved performance toy foam darts are usually at odds with the KED requirements.
It would be desirable to provide an improved foam dart toy which can provide improved distance and/or accuracy while at the same time meeting the KED requirements to avoid and/or limit damage from the impact of such toy foam darts, while also providing enhanced play features.
In one aspect, the present disclosure is directed to a toy form dart having an elongate dart body with an interior bore that extends in a longitudinal direction from a head end to a tail end of the elongate dart body, and a dart tip connected to the head end of the elongate dart body. The dart tip has a top, a bottom that is affixed into the interior bore at the head end of the elongate dart body, and an outer surface extending from the top to the bottom of the dart tip in the longitudinal direction is bounded by a cylindrical envelope. A hollow passage extends through the dart tip in a first direction perpendicular to the longitudinal direction defining first and second mouth openings on opposing sides of the dart tip. The hollow passage has an aspect ratio of at least 1:1 of a passage width in a second direction that is perpendicular to the first direction and the longitudinal direction in comparison to a passage height in the longitudinal direction. In some embodiments, the aspect ratio is 2:1, or can be 3:1 or greater. Edges of the hollow passage define the width in the first direction. These edges may be curved. First and second pairs of eye socket indents are located between the respective first and second mouth openings and the top of the dart tip, with the first and second eye socket indents penetrating only partially into the dart tip and an interior boundary wall formed between each one of the first pair of eye socket indents and each respective oppositely located one of the second pair of eye socket indents. The first and second pairs of eye socket indents and the respective first and second mouth openings form a face configuration on the opposing sides of the dart tip.
The toy darts having this configuration meet KED standards due to the hollow passageway and the eye socket indents providing an area for the dart tip, and specifically the top, to deform upon impact of the tart tip with an object, absorbing impact energy in order to greatly reduce the likelihood of injury or damage. Further, the face configuration provides additional play interest as well as the ability for a user to more easily sort toy darts from different users.
Additionally, the hollow passageway combined with the partial removals of material in the eye socket indents allow the overall weight as well as the weight distribution at the dart tip to be more accurately controlled, which provides for improved accuracy.
In one embodiment, the hollow passage has a greater opening dimension for the passage height at the edges in comparison to an opening dimension for the passage height at a medial portion. In one preferred arrangement, the opening dimension for the passage height at the edges is at least two times the opening dimension for the passage height at the medial portion.
In another embodiment, the hollow passage has a smaller opening dimension for the passage height at the edges in comparison to an opening dimension for the passage height at a medial portion.
In one embodiment, the hollow passage has a planar upper surface closer to the top of the dart tip.
In one embodiment, the hollow passage has a smaller opening dimension for the passage height at the edges in comparison to an opening dimension at a medial portion, and the edges are located closer to the top of the dart tip than a medial portion of the hollow passage.
In one arrangement, the edges are located in a plane perpendicular to the longitudinal direction that intersects a lower portion of the first and second pairs of eye socket indents. This provides improved flexibility for energy absorption.
In one embodiment, the hollow passage has a generally uniform opening dimension for the passage height, and the edges are located closer to the top of the dart tip than a medial portion of the hollow passage such that the hollow passage has a curved profile at the first and second mouth openings. This arrangement provides for a distinctive “smiley face” for the face configuration.
In some embodiments, the eye socket indents of each of the first and second pairs of eye socket indents have a circular configuration. Alternatively, the eye socket indents of each of the first and second pairs of eye socket indents have a non-circular configuration, with the eye socket indents in the first pair of eye socket indents being mirror-symmetric to one another about a longitudinal plane defined by the longitudinal direction and the first direction, and the eye socket indents in the second pair of eye socket indents being mirror-symmetric to one another about the longitudinal plane. Here the shapes can vary to provide different expressions for the face configuration.
Preferably, the dart tip is molded from a polymeric material which can be mixed with a weighting agent. In a particularly preferred embodiment, the weighting agent is calcium carbonate powder. In a particularly preferred embodiment, the calcium carbonate powder is between 10 and 20 wt % of the dart tip.
Preferably the dart tip has a weight of about 0.61 to 0.88 grams for a diameter of about inches (12.5-12.7 mm).
The top of the dart tip can be domed, flat or include a suction cup, or may have other configurations.
In another aspect, a toy comprising first and second sets of toy foam darts, preferably for use with first and second toy foam dart launchers, are provided with the first and second sets of toy foam darts each including a plurality of the foam darts as described above and in detail below. At least one of the first and second mouth openings or the first and second pairs of eye socket indents in the first set of toy foam darts are different than the first and second mouth openings or the first and second pairs of eye socket indents in the second set of toy foam darts. This provides “opposing” sets of toy foam darts for enhanced play by two or more users, with the first and second sets of toy foam darts having a different face configuration.
In another aspect, a toy form dart is provided that has an elongate dart body having an interior bore that extends in a longitudinal direction from a head end to a tail end of the elongate dart body and a dart tip connected to the head end of the elongate dart body. The dart tip has a top, a bottom that is affixed into the interior bore at the head end of the elongate dart body, and an outer surface extending from the top to the bottom of the dart tip in the longitudinal direction. The tip is formed of a polymeric material mixed with powdered weighting agent in order to achieve a desired weight for the dart tip. The amount of the weighting agent can be adjusted to achieve the desired weight in order to compensate for various configurations of the dart tip.
In one embodiment, the powdered weighting agent is between 10 and 20 wt % of the dart tip. The powered weighting agent can be calcium carbonate or any other suitable material.
In another embodiment, the dart tip weights 0.61 to 0.88 grams.
It is noted that various ones of the above-noted features can be used alone or in combination with one another to arrive at different toy foam dart configurations.

As shown in
A hollow passage 32 extends through the dart tip 20 in a first direction Y perpendicular to the longitudinal direction X, defining first and second mouth openings 33.1, 33.2 on opposing side of the dart tip 20. The hollow passage 32 preferably has an aspect ratio of at least 1:1 of a passage width W in a second direction Z that is perpendicular to the first direction Y and the longitudinal direction X, in comparison to a passage height h2 in the longitudinal direction X. In most embodiments, the aspect ratio is at least 2:1, and more preferably 3:1 or greater. The edges 34.1, 34.2 of the hollow passage 32 define the width W in the first direction Y. These edges are preferably curved; however, they could be other shapes. However, this curvature as well as the shape of the hollow passage can vary as explained in detail below.
Still with reference to
The first and second pairs of eye socket indents 36.1, 36.2; 38.1, 38.2 and the respective first and second mouth openings 33.1, 33.2 form a face configuration on opposing sides of the dart tip 20. This face configuration on the opposing sides of the dart tip 20 is preferably the same, at least with respect to the first and second mouth openings 33.1, 33.2.
The hollow passage 32 that extends through the dart tip 20 allows flexibility of the surface that reduces surface impact and permits passing of the KED test for safety. In the present case, the dart tip 20 is molded from a polymeric material, preferably thermoplastic rubber. However, other materials could be used. Additionally, preferably a powdered weighting mixture is added to the polymeric material prior to molding. In one preferred embodiment, the powered weighting material is calcium carbonate powder and is preferably between 10 and 20 wt % of the dart tip 20. Those skilled in the art will recognize that other weighting materials can be used. In one preferred arrangement, the dart tip 20 weighs between 0.61 and 0.88 grams. However, the weight could vary depending upon the particular application. Additionally, the amount of weighting material can increase or decrease depending on the volume of the hollow passage 32 and the pairs of eye socket indents 36.1, 36.2; 38.1, 38.2 in order to achieve the desired weight. Additionally, the dart tip 20 preferably has a durometer that is between 20 and 80. More preferably, the durometer is between 30 and 40.
The hollow passage 32 together with the eye socket indents 36.1, 36.2; 38.1, 38.2 allow the weight of the dart tip 20 to be accurately controlled in order to meet KED testing as well as provide superior flight characteristics for the toy foam dart 10. Further, the configuration of the hollow passage 32 that forms first and second mouth openings 33.1, 33.2 along with the eye socket indents 36.1, 36.2; 38.1, 38.2 on the respective sides of the dart tip 20 make the dart 10 more interesting and provide additional play value for, in particular, juvenile users.
While the dart tip 20 is preferably made of injection molded thermoplastic rubber including the weighting material, it is also possible to form the dart tip 20 from other materials via other processes.
In the first embodiment of the toy foam dart 10, the hollow passage 32 has a greater opening dimension for the passage height h2 at the edges 34.1, 34.2 of the hollow passage 32 in comparison to an opening dimension for the passage height h1 at the medial portion. This specific arrangement provides for more uniform impact absorption around the periphery of the dart tip 20 given the greater material removal away from the medial area toward the edges 34.1, 34.2. Preferably, the opening dimension for the passage height h2 at the edges 34a, 34b is at least two times the opening dimension for the passage height h1 at the medial portion.
Additionally, a width W of the hollow passage 32 in the second direction Z is preferably at least 60% of the diameter D of the dart tip 20. More preferably, the width W is between 70 and 85% of the diameter D of the dart tip 20.

For enhanced play value, the disclosure also provides for a toy that includes first and second sets of the toy foam darts 10 having different tips 20, 20a-20h as described above. These first and second sets of toy foam darts 10 with tips 20, 20a-20h each include a plurality of the foam darts 10 and at least one of the first and second mouth openings or the first and second pairs of eye socket indents in the first set of toy foam darts 10 are different than respectively, at least one of the first and second mouth openings or the first and second pairs of eye socket indents in the second set of toy foam darts 10. This allows users to more easily sort their darts 10 based on the different face configuration. This also allows for selecting custom sets of toy foam darts 10 that are suited to a particular user. Further, having differentiated toy foam darts 10 allows for users to have enhanced play by creating different scenarios or games that involve the thus differentiated toy foam darts 10 having dart tips 20, 20a-20h with different face configurations.
Having thus described the presently preferred embodiments in detail, it is to be appreciated and will be apparent to those skilled in the art that many physical changes, only a few of which are exemplified in the detailed description of the invention, could be made without altering the inventive concepts and principles embodied therein. It is also to be appreciated that numerous embodiments incorporating only part of the preferred embodiment are possible which do not alter, with respect to those parts, the inventive concepts and principles embodied therein. The present embodiments and optional configurations are therefore to be considered in all respects as exemplary and/or illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all alternate embodiments and changes to this embodiment which come within the meaning and range of equivalency of said claims are therefore to be embraced therein.
