Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

In general, the present invention relates to a toy arrow for use with a toy bow in toy bow and arrow systems, where the toy bow is used to launch the toy arrow projectile into flight.

2. Prior Art Description

Bow and arrow sets that are designed for children's play have existed throughout recorded history. In the modern era, toy bow and arrow sets typically have a plastic molded bow, a string, and safety-tipped arrows. To ensure safety, the functional design of a toy bow is also commonly altered. In a real bow, the string has a fixed length. The spring force used to launch an arrow comes from the flexing of the arms of the bow. The problem with this design is its failure mode. If a bow is drawn beyond its limit, then the arms or the string of the bow may break. Depending upon where the breakage occurs, the broken string and/or bow may fly toward the person holding the bow as the stored energy is accidentally released.

To reduce the likelihood of this hazard from occurring, many toy bows are manufactured as static structures. An elastic string is used to create the arrow launching force. If such a bow is overdrawn, there is no significant chance of the bow breaking. Rather, the elastic string will break and will most likely move in a direction away from the person drawing the bow. The failure mode of a string breaking is far less dangerous than the failure mode of the bow breaking. However, the failure mode of a broken string does present some danger depending upon where the elastic string breaks and how much energy is stored in the elastic string at the time it breaks.

Toy bows that use a static bow and an elastic string are exemplified by U.S. Pat. No. 5,247,920 to Harbin, entitled Toy Bow; and U.S. Pat. No. 7,748,369 to Chee, entitled Launching Apparatus and Assembly.

Many toy bows that have elastic strings use elastic strings that are made from a synthetic polymer, such as silicon, TPR, or some other synthetic rubber. On the toy, such elastic strings are constantly under tension. As such, if the material of the string creeps or degrades, the elastic string will break. This stops the toy bow from being functional.

Most all plastic degrades in some fashion over time. However, it has been found that one of the fastest ways to degrade the preferred polymers used for the bowstring is to expose the bowstring to UV light. A bowstring that can last for months inside a home may only last for a few days if taken outside and left in sunlight. A toy that lasts for months is acceptable. A toy that lasts for days is not. Damage caused by exposure to light has therefore caused products to be returned and/or consumer's dissatisfaction with the toy manufacturer.

A need exists for a toy bow and arrow design that inhibits degradation in the elastic string caused by exposure to light. This need is met by the present invention as described and claimed below. A need also exists for a toy bow and arrow design that inhibits degradation in the elastic string caused by exposure to UV light, yet provides enhanced aesthetics using internal lighting that does not contain significant UV wavelengths. This need is met by the present invention as described and claimed below.

SUMMARY OF THE INVENTION

Described herein is a toy projectile that has extending hooks. The hooks on the projectile engage the elastic elements. When the projectile is drawn back, the elastic elements stretch and provide the spring energy needed to launch the projectile into flight when it is released.

Described herein is a toy projectile that has a shaft with a head end and a tail end. A head is associated with the head end of the shaft. Fins are associated with the tail end of the shaft. Extending hooks extend outward from the sides of the head. The head may be an enlarged head. The extending hooks may be a pair of extending hooks extending outward from opposite sides of the head. Preferably, a first end of each of the extending hooks is associated with the head, a second end of each of the extending hooks is distal from the head, and the second end extends towards the shaft and the fins.

Described herein is a toy bow assembly that is used to launch toy projectiles. The toy bow assembly includes a bow structure having a first arm section and a second arm section. Both the first arm section and the second arm section have sheathed areas that are protected from ambient light. A central area is disposed between the first arm section and the second arm section.

A first elastic element is anchored to the first arm section. The first elastic element extends through the first sheathed area into the central area, wherein the first sheathed area shields the first elastic element from exposure to ambient light. Likewise, a second elastic element is anchored to the second arm section. The second elastic element extends through the second sheathed area and into the central area, wherein the second sheathed area shields the second elastic element from exposure to ambient light. This prevents the elastic elements from degrading due to exposure of UV light contained in ambient light.

Described herein is a toy bow assembly that is used to launch toy projectiles. The toy bow assembly includes a bow structure having a first arm section and a second arm section. Both the first arm section and the second arm section contain at least one translucent area.

Lights are disposed within both the first arm section and the second arm section. The lights internally illuminate the translucent areas of the first arm section and second arm section when activated.

An activation switch is disposed on the bow structure for selectively activating and deactivating the lights.

A first elastic element is anchored to the first arm section. The first elastic element extends through the first arm section into a central area. The first arm section shields the first elastic element from exposure to ambient light. Likewise, a second elastic element is anchored to the second arm section. The second elastic element extends through the second arm section and into the central area. The second arm section shields the second elastic element from exposure to ambient light. This prevents the elastic elements from degrading due to exposure of UV light contained in ambient light.

DETAILED DESCRIPTION OF THE INVENTION

In co-pending U.S. patent application Ser. No. 13/902,968, the applicant presents a toy bow where the elastic bowstring is encased and protected from UV light in the ambient atmosphere. However, in shielding the bowstring, the toy bow loses some aesthetics. The shielding over the bowstring, however, provides an opportunity to provide unique improved aesthetics through the use of internal lighting, and this is shown in co-pending U.S. patent application Ser. No. 14/016,164. These two applications are combined in the present application. Like elements are referred to with like reference numbers.

Whereas the parent applications focus on the toy bow, the present application focuses on the toy arrow that is shown and described in U.S. patent application Ser. No. 13/902,968 and U.S. patent application Ser. No. 14/016,164 as well as U.S. patent application Ser. No. 12/878,985 (which is the parent of both U.S. patent application Ser. No. 13/902,968 and U.S. patent application Ser. No. 14/016,164).

Specifically described herein is a toy projectile 14 (also referred to as an arrow projectile, a projectile, or a toy arrow) that has extending hooks 20. The hooks 20 on the toy projectile 14 engage the elastic elements of the toy bows 12. When the projectile 14 is drawn back, the elastic elements stretch and provide the spring energy needed to launch the projectile 14 into flight when it is released. Unless specified otherwise, the toy projectile 14 (FIGS. 1 and 4) and the toy projectile 14′ (FIG. 7) are described together as toy projectile 14.

Although the toy bow and arrow system can be embodied in many ways, only the shown exemplary embodiments of the present invention system are illustrated. These embodiments are selected in order to set forth the best mode contemplated for the invention. The illustrated embodiments, however, are merely exemplary and should not be considered a limitation when interpreting the scope of the appended claims.

Referring to FIGS. 1 and 4, a bow and arrow system 10 (shown as system 10a and system 10b, but referred to generally as system 10) is shown. The bow and arrow system 10 includes a bow structure 12 (shown as bow 12a and bow 12b, but referred to generally as bow 12) and at least one arrow projectile 14. The bow structure 12 is rigid. The force used to propel the arrow projectile 14 is provided by two separate and distinct loading loops 16. The arrow projectile 14 has hook projections 20 that engage both of the loading loops 16. Elastic elements 18 extend through the loading loops 16. As a person engages an arrow projectile 14 with the loading loops 16 and pulls on the arrow projectile 14, the elastic elements 18 in the loading loops 16 stretch. Since there are two loading loops 16, the elastic element 18 in each of the loading loops 16 need only provide half the force needed to propel the arrow projectile 14 into flight. The elastic elements 18 are therefore difficult to overstretch in the proper operation of the toy. Furthermore, should either of the elastic elements 18 or loading loops 16 suddenly break, the orientation of the broken elastic elements 18 prevents the elastic elements 18 or the loading loops 16 from whipping toward the user. This dynamic is explained later in greater detail. Lastly, since the arrow projectile 14 engages two separate and distinct loading loops 16, the chances of the elastic elements 18 in both loading loops 16 breaking simultaneously are highly improbable. Accordingly, if one elastic element 18 breaks, the arrow projectile 14 will still be engaged by the other loading loop 16 and the person pulling the arrow projectile 14 back will not pull the arrow projectile 14 into himself upon the breakage of the one loading loop 16.

Referring to FIGS. 2 and 5 in conjunction with FIGS. 1 and 4, it can be seen that the bow structure 12 is a rigid molding. The bow structure 12 has a first end 22, a second end 24 and a handle 26 in its central region. The handle 26 has a top end 25 and a bottom end 27. A first arm section 28 is supported above the top end 25 of the handle 26. Likewise, a second arm section 30 is supported below the bottom end 27 of the handle 26. The first arm section 28 and the second arm section 30 are oriented in a common vertical plane. The handle 26 is offset from the common vertical plane so as not to interfere with the path of the arrow projectile 14. This creates an open central region 15 between the first and second arm sections 28, 30 that is defined by the handle 26.

The first arm section 28 contains a sheath structure 35 that defines a first internal compartment 37. The first internal compartment 37 has a bottom end 39 that faces toward the open central region 15. Likewise, the second arm section 30 contains a sheath structure 41 that defines a second internal compartment 43. The second internal compartment 43 is has a top end 45 that faces toward the open central region 15. In FIGS. 1-3, both sheath structures 35, 41 are opaque. In FIGS. 4-6, both sheath structures 35, 41 have forward-facing surfaces 49 that are translucent.

FIGS. 4-6 also show one or more light emitting diodes 51 are mounted inside each of the sheath structures 35, 41. When the light emitting diodes 51 activate, they internally illuminate both the first internal compartment 37 and the second internal compartment 43. This internal illumination can be viewed from an external point through the translucent areas 49 on both sheath structures 35, 41. Although only one or a few light emitting diodes 51 may be used in each of the internal compartments 37, 43, the internal illumination causes the translucent areas 49 to glow brightly wherever they are backlit by the internal illumination.

The light emitting diodes 51 shown in FIGS. 4-6 are preferably monochromatic and emit light between the green and red wavelengths of the visible spectrum. Such light contains no significant ultraviolet components. The light produced by the light emitting diodes 51, therefore, produces no significant degradation in the polymers of the elastic elements 18. As such, the light emitting diodes 51 can emit bright light without adversely affecting the lifespan of the elastic elements 18.

The light emitting diodes 51 shown in FIGS. 4-6 are powered by batteries 53. The batteries 53 are contained within a battery compartment 55 that is manufactured into the bow structure 12b. Although a battery compartment can be positioned within the first arm section 28 or the second arm section 30, it is preferred that the battery compartment 55 be placed within the structure of the handle 26.

When using the bow and arrow system 10, a person grasps the handle 26 of the bow structure 12b. As such, it is preferred that if there is an on/off switch 55 (such as that shown in shown in FIGS. 4-5) positioned on the handle 26 in a position that can easily be operated by a person grasping the handle 26 of the bow structure 12b. In the preferred embodiment, the on/off switch 55 is a normally “off” switch that turns “on” only when actively pressed. The on/off switch 55 can be integrated into the handle 55 so that the on/off switch is activated merely by firmly grasping the handle 26 of the bow structure 12b.

Two pivot post structures or post structures 31, 32 are mounted to the bow structure 12 outside the bottom opening 39 of the first sheath structure 35 and the top opening 45 of the bottom sheath structure 41. Referring now to FIGS. 2 and 5 in conjunction with FIGS. 3 and 6, it will be understood that although FIGS. 3 and 6 show only one of the post structures 31, the description offered stands for both post structures 31, 32 equally. Each pivot post structure 31, 32 defines two narrow channels 40. In FIGS. 3 and 6, only one channel 40 is shown. It will be understood that a second channel lay below the shown channel 40 in a parallel configuration.

Each of the loading loops 16 is a loop structure of an elastic element 18 that creates two runs 47, 48. The runs 47, 48 of each elastic element 18 extend through the sheath structures 35, 41 and through the two pivot posts 31, 32. Each elastic element 18 has two ends. Both ends of each elastic loop 18 are affixed to anchored posts 44, 46 within the sheath structure 35, 41. Since the runs 47, 48 of each elastic element 18 extend through the sheath structures 35, 41, it will be understood that the material of the elastic elements 18 is shielded from any external light exposure until the elastic elements 18 are stretched out of the channels 40 in the pivot post structures 31, 32.

The length of the elastic element 18 has a cross section that is smaller than the diameter of the channels 40 in the pivot post structures 31, 32. In this manner, a separate run 47, 48 of the elastomeric element 18 can pass through each of the openings 40, therein keeping the two runs 47, 48 of the loop apart.

As the runs 47, 48 of the elastic element 18 pass out of the pivot post structures 31, 32, the elastic element 18 immediately passes into reinforcement tubes 50 to form the loading loops 16. The diameters of the reinforcement tubes 50 are larger than the channels 40 in the pivot post structures 31, 32. Consequently, the reinforcement tubes 50 cannot pass through the pivot post structures 31, 32. As a result, each length of the elastic element 18 is divided into two runs 47, 48. The first run 47 extends between an anchor post and the reinforcement tube 50 on the far side of the pivot post structure. The second run 48 extends from the reinforcement tube 50 back to the anchor post. The looping of the elastic element 18 between the two runs 47, 48 curves the reinforcement tubes 50 and creates the two loading loops 16.

Additionally, the presence of the reinforcement tubes 50 protects the elastic element 18 inside the loading loops 16 from exposure to external light. Consequently, when the elastic elements 18 are at rest, the entire length of each of the elastic elements 18 is shielded from external ambient light.

Due to the offset of the handle 26, an open central region 15 exists between the two pivot post structures 31, 32. The loading loops 16 each extend into the open central region 15 from opposite sides.

Referring to FIG. 7 in conjunction with FIGS. 1 and 4, it can be seen that the arrow projectile 14′ has two hook elements 20′ extending from opposite sides. The hook elements 20′ are sized and shaped to engage the two loading loops 16 as the hook elements 20′ are pulled through the open central region 15. (The arrow projectile 14′ and hook elements 20′ have slightly different designs from, but are functionally equivalent to the arrow projectile 14 and hook elements 20 described in relationship with the other figures. Unless specified otherwise, the general phrases arrow projectile 14 and hook elements 20 (and equivalent phrases) are meant to encompass the arrow projectile 14′ and hook elements 20′ of FIG. 7.) To load the arrow projectile 14, the arrow projectile 14 is positioned within the open central region 15 so that the hook elements 20 engage the loading loops 16. Once engaged with the loading loops 16, the arrow projectile 14 is pulled in the manner of a traditional bow and arrow. As the arrow projectile 14 is pulled away from the open central region 15, the elastic elements 18 stretch. The elastic elements 18 bend around the pivot post structures 31, 32, therein enabling the loading loops 16 to move with the arrow projectile 14. This is the only time that parts of the elastic elements 18 are exposed to ambient light. This exposure lasts only for as long as the elastic elements 18 are stretched. Thus, the exposure to ambient light only lasts for a few seconds during each shot cycle.

As the elastic elements 18 stretch, they store energy. When the arrow projectile 14 is released, the elastic elements 18 retract and the arrow projectile 14 is accelerated toward the open central region 15. At the open central region 15, the loading loops 16 retract against the pivot post structures 31, 32. The momentum of the arrow projectile 14 causes the arrow projectile 14 to continue its forward movement beyond the open central region 15. This launches the arrow projectile 14 into flight as the hook elements 20 disengage the loading loops 16.

When the elastic elements 18 are stretched, they are most vulnerable to breakage. If one of the runs 47, 48 of an elastic element 18 breaks before passing through a pivot post structure 31, 32, then the speed of the contracting broken elastic element 18 is slowed by its passage through the pivot post structure 31, 32. This prevents a broken run from whipping toward a user. Furthermore, if the elastic element 18 were to break after it passes the pivot post structure 31, 32, most of the potential energy serves to move the broken elastic element 18 back toward the pivot post structure 31, 32 and away from the user.

Both immediate parent applications of the present application and the parent of the immediate parent applications describe the toy projectile 14 as having extending hooks 20 (also referred to as hook projections and hook elements) extending from opposite sides that engage the elastic elements of the toy bows 12. Both parent applications also show two versions of the toy projectile that are now shown as toy projectile 14 (FIGS. 1 and 4) and toy projectile 14′ (FIG. 7) that are together referred to as toy projectiles 14. As shown, the toy projectiles 14 have a shaft 11 with a head end and a tail end. As shown, an enlarged head 13 is associated with the head end of the shaft 11. As shown, fletching or fins 17 are associated with the tail end of the shaft 11. As shown, two extending hooks 20 extend outward from opposite sides of the enlarged head 13 such that a first end of each extending hook 20 is associated with the enlarged head 13 and a second “free” end of each extending hook 20 is distal from the enlarged head 13. The “free” ends of the extending hooks 20 point away from the tip of the enlarged head 13 and generally extend towards the shaft 11 and fins 17.

It will be understood that the embodiment of the present invention that is illustrated and described is merely exemplary and that a person skilled in the art can make many variations to that embodiment. For instance, the bow structure can have many different ornamental shapes. The bow structure can also take the form of a crossbow. Likewise, the arrow projectiles can be configured as airplanes, rocket ships or any other flying projectile. All such embodiments are intended to be included within the scope of the present invention as defined by the claims.
