The present disclosure relates generally to projectile launching toys. In particular, the present disclosure describes specialized flying discs and disc launching devices configured to launch and retrieve flying discs without requiring direct user contact with the disc,
Commonly knonw flying discs like Frisbee™, or similar but more unique discs like the Aerobic™, have been around for some time. These flying discs are used to play catch, disc sports, and even fetch with animals. The discs are typically thrown, caught and retrieved from the ground by hand. Known flying discs an launching devices are not entirely satisfactory for the range of applications in which they are employed. For example, disc launching devices often include needlessly complex designs that reduce their entertainment value. Such complex designs often make it difficult to launch a disc and frustrate the user. Other designs do not provide the user with sufficient stability and control when a disc is launched.
In addition to complex designs, existing devices fail to provide sufficient launching power to propel the disc any considerable distance. Awkward launching devices and hand throwing discs can make propelling the disc difficult. Poorly designed devices and hand throwing discs also cause strain the user. Existing devices and launching approaches do not offer the leverage necessary to propel the disc with sufficient speed to keep the disc in the air.
Known disc launching devices also do not satisfactorily retrieve flying discs n the ground after being launched. Specifically, many disc launching devices are unable to retrieve flying discs when the disc is in difficult to reach locations and/or when the disc is laying with its top facing the ground. Without sufficient means for retrieval, existing devices force the user to retrieve the disc by hand. Often, dirt, water, mud, or other substances make handling the disc undesirable,
The present disclosure is directed to specialized flying discs and launching devices having a launching arm that can be held by a user, the arm being coupled to a flying disc via a coupler disposed at the launching end of the arm, and an attachment member disposed on the periphery of the flying disc. When swung by the user with appropriate force, the disc becomes un-coupled from the arm and takes flight. In some examples, the attachment members define distinct attachment nodes disposed within attachment openings. In some other examples the attachment member defines a concentric ring disposed on the periphery of the disc.
The disclosed specialized flying discs and launching devices will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
Throughout the following detailed description, examples of various specialized flying discs and launching devices are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity; related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
With reference to
The arm 110 of disc launching device 100 is capable of adding leverage, reach, spin, speed, and thrust to a disc 130 and causing disc 130 to fly. Arm 110 can also aid in recovery of the disc from the ground, or from hard-to-reach places. The arm includes a gripping d 112, launching end 114, and the launching end having a coupler 116, coupled to a flying disc 130.
As shown in
As
Disc 130 may be weighted according to desired flight characteristics. In this example disc 130 is a medium weight disc. In another embodiment, the disc is weighted snore heavily. In yet another embodiment, the disc is lighter resulting in differing flight characteristics.
The aerodynamic design of disc 130 is conducive to achieving stable flight when thrown or launched with a selected amount of force and spin. In some examples, the design is more or less aerodynamic, providing a selectable number of flight characteristics.
The parabolic shape of the central body of disc 130 results in a convex top side and a concave bottom side. In the instant example, disc 130 is sufficiently concave to provide for lift when the disc is thrown. This lift can allow increased hang time for the launched disc. In another example the concave shape is significantly reduced to an almost uniformly flat body. Such variations in the disc size and concave shape create more distinct flying characteristics and trajectory patterns. The aerodynamic considerations of the flying discs in all examples are selectable according to desired trajectory and flight characteristics.
In the example shown in
The durability and material construction of certain disc examples make it especially suitable for use as a dog toy. Yet others are suitable for launching between users. Other discs are suitable for various disc sport applications.
As
The shape of attachment members in the instant example is largely cylindrical to match the shape of coupler 116. In another example, the attachment members have an elliptical cross section. In a different example, the attachment members have a teardrop cross section. In yet other examples, the attachment members are any shape that allows coupling and un-coupling of the disc from arm 110.
Attachment member openings 132 allow coupler 116 of arm 110 to engage one of the attachment member 134 from any angle around the longitudinal axis of attachment members 134. As a result, arm 110 may selectively engage attachment member 134 from positions approaching the top side or bottom side of disc 130 or around the periphery of disc 130.
The plurality of attachment members 134 interspersed around the perimeter of disc 130 afford arm 110 and coupler 116 greater access to attachment member 134 when directly engaging disc 130 from the ground. The spacing of attachment member 134 around the perimeter and the greater access to attachment member 134 through attachment member openings 132 collectively allow arm 110 to directly engage disc 130 from a variety of landing positions.
Turning our attention now to
Gripping end 112 is held by a user when swinging arm 110 causing launching end 114 to gain speed. In the instant example, gripping end 112 includes a handle 113 contoured to comfortably fit a user's hand profile. In another example, handle 113 is a malleable grip. Any conventional handle suitable for manipulating the launching device may be used. In yet other examples the gripping end 112 of arm 110 terminates without a handle.
Turning specifically to
Arm 110 is sufficiently rigid to withstand the force necessary to launch disc 130 when arm 110 is swung. Although arm 110 may flex when swung with sufficient force, it is sufficiently resilient to return to its original shape after disc 130 is launched.
As shown in
A disc coupling event occurs when attachment members 134 are received into coupler 116. On the other hand a de-coupling event occurs when disc launching, device 100 is swung with sufficient force to cause coupler 116 to disengage attachment member 134. Upon coupling, disc 130 becomes oriented along the swing plane of disc launching device 100.
Turning attention to
Looking again to
In the example shown in
In another example where different release characteristics are desired, the resiliencies of the first and second fingers are the same. In a different example, the resiliency levels of both fingers is very high, requiring a larger amount of force for decoupling and causing increased disc speed and distance. In certain examples, the resiliencies are selected to inhibit the coupler from disengaging the attachment members before intended by the user. In yet other examples, the resiliencies are selected based upon the mass of the disc and the angular acceleration of a desired swing.
In the instant embodiment, first finger 120 and second finger 122 are made from a semi-rigid plastic material. In another example, the fingers are made from polyurethane. In a different example, the fingers are constructed from polyvinyl chloride. In yet other examples, the fingers are constructed from any material sufficiently resilient to accomplish a coupling and de-coupling event.
As can be seen in
As a result of channel 124's complimentary shape, disc 130 selectively rotates transverse the swing plane while engaged within coupler 116. Such selective rotation may be particularly useful when arm 110 is used to engage disc 130 directly from the ground and disc 130 is not properly aligned with arm 110.
Further, the cylindrical bearing defined by channel 124 enables disc 130 to rotate relative to coupler 116 as launching device 100 is swung to launch disc 130. As launching device 100 is swung, disc 130 naturally rotates due to the rotational dynamics in the cylindrical bearing to a position where palm portion 118, first finger 120 and second finger 122 are substantially horizontal. By rotating to a substantially horizontal orientation before being released by coupler 116, disc 130 is thrown in a stable orientation conducive for flight.
Upon launching disc 130 in a de-coupling event, a user holding gripping end 112 and swings arm 110 in a swing direction until a threshold force acting on coupler 116 is achieved. The user's swing applies forward momentum to the disc 130. When arm 110 is swung with sufficient force, the resulting angular momentum acting on disc 130 overcomes the clamping force of coupler 116 and disc 130 de-couples and takes flight.
As disc 130 is launched from launching end 114, launching end 114 applies a forward momentum on disc 130 substantially aligned with the swing direction. This forward momentum is focused on the center of disc 130, causing disc 130 to launch substantially aligned with the swing direction. Additionally, coupler 116 applies a force to attachment members 134 in a direction substantially opposite the swing direction and focused substantially at the perimeter of disc 130. The misalignment of the forward momentum applied by launching end 114 and the opposing force applied by coupler 116 causes disc 130 to spin as it launched, leading to greater horizontal stability during flight. Increasing the rate at which the disc spins has been observed to increase the stability of the disc in flight.
