The present disclosure generally relates to a multifunctional broadhead for an archery arrow that has both a mechanical and fixed configuration. The disclosure is also directed to multifunctional mechanical arrow broadheads that deploy blades upon contact with a target with the ability to transition to a broadhead configured with the blades in a deployed and fixed position prior to target contact. Mechanical broadheads typically include blades that remain in a stowed and aerodynamic position during the time of flight of an arrow. Upon contact with a target, the blades deploy to an open or extended position. The present disclosure is directed to universal/multifunctional broadheads that are configured to transition from a mechanical blade configuration to a fixed blade configuration and back again.
An arrow launched from a bow typically includes a shaft, stabilizers or fins known as fletchings and an arrowhead. Various types of arrowheads exist such as a broadhead used by hunters. A broadhead typically includes two to four sharp cutting-blades to injure or kill a target. Bow hunters typically use two main types of broadheads and include fixed-blade broadheads and mechanical broadheads. Fixed-blade broadheads maintain blades in a rigid, extended, and immovable position, and a mechanical broadhead deploys its blades from a retracted or stored position, to an extended or deployed position upon contact with the target. In most cases, the arrow with the mechanical broadhead flies better because it is more aerodynamic due to the retracted blades, but has less penetration compared to the fixed-blade broadhead since the mechanical broadhead uses some of the kinetic energy in the arrow to deploy its blades upon target impact.
Thus, all broadheads fall under two classifications as recognized by the archery industry: 1) fixed; and 2) mechanical. Hybrid variations exist, but all hybrids fall in the mechanical classification according to state hunting regulations. The present disclosure describes a universal or multipurpose broadhead with a universal ferrule (i.e., broadhead body) with the ability to transition back and forth between a mechanical mode and a fixed mode, according to the user's requirements and desires, while still maintaining superior dynamic flight characteristics across all modes. And maintaining the same grain weight. One skilled in the art of designing and manufacturing of broadheads will understand that the weight variations can fluctuate with the material batches and machining practices, but within the accepted weight tolerances and within industry standards.
Historically, bow hunters have chosen either fixed or mechanical based upon mandated state hunting regulations. However, using a mechanical broadhead for certain game species, and using a fixed broadhead for other game species results in different dynamic flight characteristics due to vastly different broadheads with a different ferrule designs. Such a limitation results in unpredictable accuracy and poor training habits. The broadhead disclosed herein, however, minimizes such shortfalls by allowing an archer to easily transition between interchangeable mechanical blades and fixed blades. Such a capability also provides a flexible broadhead that is legal and in accordance with the hunting regulations of all 50 states.
Currently, no such multifunctional broadhead exists to allow an archer to use a broadhead with a single universal ferrule that can transition back and forth between fixed and mechanical configurations. Most broadhead manufacturers understand that the ferrule is typically the strongest part of the broadhead. Thus, replacement blades are sold, but only for configurations that the broadhead was originally available. The broadhead, blade configurations, and related ferrule disclosed herein provide an archer with greater cost savings, enhanced accuracy in both fixed and mechanical broadhead configurations that are suitable for a wide range of hunting needs.
This disclosure generally relates to multifunctional broadheads and universal ferrules for an archery arrow that have both mechanical and fixed configurations. The disclosure is directed to multifunctional mechanical arrow broadheads that deploy blades upon contact with a target and have the ability to transition to a broadhead configured with the blades in a deployed and fixed position prior to target contact.
In accordance with an exemplary illustrative embodiment, a multifunctional arrow broadhead is disclosed comprising a ferrule that includes a plurality of slots and at least one screw/pin. In some examples, the broadhead may include at least two blades that are configured to engage the plurality of slots in the ferrule. In other examples, the screw/pin may secure the blades to the ferrule. In yet other examples, the multifunctional broadhead may include a base and the blades may be further configured to function in a first mode and the two blades may also be further configured to function in a second mode. In still other examples, the first and second modes may be user selected.
In other examples, the first mode may be a fixed blade configuration in which the blades may be extended in a deployed position. In some examples, the second mode may be a mechanical configuration in which the blades may be further configured in a retracted position throughout an arrow time of flight and the blades may deploy to an extended position upon impacting a target. In yet another example, the blades may be configured to pivot from the retracted position to the extended position on an axis of the screw/pin and the blades may extend through the plurality of slots in the ferrule. In another example, the ferrule may include a third blade. In still other examples, the ferrule may include a fourth blade.
In certain examples, the ferrule may further include a media hole in which the blades may be held in the retracted position by insertion of a media into the media hole forming a friction fit. Upon target impact, the blades may deploy into the extended position. In other examples, the media may be a nylon, a polymer blend, or combination thereof.
In still other examples, the cutting diameter of the blades may be at least 2 inches when the blades are extended in the first or second modes. In other examples, the blades may form an angle from about 90 to 120 degrees when the blades are in the extended position. In some examples, at least two thirds of the blades may be contained within the ferrule when the blades are in the second mode. In another example, the ferrule may be aluminum, carbon, steel, or titanium. In yet another example, the base may be threaded and configured to removably engage an arrow shaft or an arrow insert. In other examples, the blades may have a thickness from 0.020 inches to 0.085 inches. In certain examples, the ferrule may have a length of at least 1.25 inches and a diameter of at least 0.220 inches. In another example, the ferrule may further include a sharpened tip or a fixed blade. In still other examples, the weight of the broadhead may be between 115 and 125 grains.
In accordance with another embodiment, a method of forming a multifunctional arrow broadhead is disclosed comprising forming a ferrule that may include a plurality of slots and at least one screw/pin. In other examples, the method may include forming at least two blades that may be configured to engage the plurality of slots and the screw/pin may secure the blades to the ferrule. In yet another example, the method may include forming a base that may be threaded and may be configured to removably engage an arrow shaft or an arrow insert. In other examples, the blades may be formed configured to function in a first mode. In other examples, the blades may be formed configured to also function in a second mode. In some examples, the first and second modes may be user selected. In certain examples, the first mode may be a fixed blade configuration with the blades extended in a deployed position. In still other examples, the second mode may be a mechanical configuration in which the blades may be further configured in a retracted position throughout an arrow time of flight and the blades may deploy to an extended position upon a target impact.
