ABSTRACT:
RELATED APPLICATIONS
Applicant has no and is aware of no applications for patent by others that should be considered with regard to the prosecution of this application.
SPONSORSHIP
Applicant has not been either Federally or Independently sponsored in affording this invention, all the invention being all his own effort.
FIELD OF THE INVENTION
This invention relates generally to what is commonly known as an expanding or expandable broadhead tip for arrows and more specifically to such a expanding or expandable broadhead including a blade carrying body slidably mounted on the tip body, having the blades thereof being rotatably carried thereon and held in closed position against the body during storage or flight by their contact with a restraining element which is overcome when the body slides rearwardly upon striking an object with the blades being subsequently cammed outwardly by a camming surface of a fixed positioning device which is positioned adjacent to the arrow shaft front portion.
SHORT SUMMARY OF THE INVENTION
An expandable broadhead arrow tip that includes a primary body positionable on the end of the arrow shaft with the primary body providing a penetration tip, a secondary body slidably positioned thereon and a combined stop and blade camming element. The secondary body carries a plurality of rotatably mounted blades which are normally restrained against rotation by a restraining element carried on an upper surface of the fixed, primary body element. As the secondary body is moved rearwardly on the primary body, the blades override the restraining element and are forced radially outwardly by the frontal camming surface of the fixed, primary element.
During normal flight, the blades are secured in folded position upon the carrying, sliding body by a restraining element. When the penetrating tip strikes a target, the target forces the sliding body rearwardly to cause the rotatable blades to be shifted outwardly as they abut with a fixed cam element and into a position in which they will provide an enlarged entrance into the target.
BACKGROUND AND OBJECTS OF THE INVENTION
Expandable broadhead arrow tips are not new to the art. Many of these tips, however include a complex mechanical mounting for the rotatable blades of the tip. Applicant provides an expandable broadhead arrow tip that meets the standards of many states which require such tips to be of specified radial dimensions in both their folded and expanded conditions while providing an effective cutting or penetration opening for the swift dispatch of an animal.
Unlike other expandable broadheads that fold back into cutting position, applicant's design provides that the blades lie rearwardly and are cammed into cutting position. Such a design is stronger and more stable than previous broadheads and also eliminates arrow deflection on angled hits upon the target which is deflection is characteristic of complete foldback tips.
Applicant provides, at least in one form, a carrying body which includes a penetrating tip, and area of reduced diameter axially therebehind, a sliding body on such on such area of decreased diameter and a stationary stopping and camming member. The stopping and camming member includes a frontal camming surface which contacts the blades of the tip to move them outwardly into full cutting diameter. The blades, when in folded position rest upon an upper surface of such stop and are held in such position by a restraining member.
All of the elements of the Applicant's tip provide simply replaceable portions such that in the field replacement and repair may be easily accomplished. The Applicant's concept also provides for alignment of the cutting surfaces of the penetrating tip and the blades thereof.
Applicant's design also allows for ease of blade replacement by simply replacing the blade carrying body. The blade retaining element provided by applicant is reusable and by simply removing this element, the tip may be shot in an open position and meet the legal cutting diameters as set by various states.
With Applicant's device, the blade carrying member may be slid rearwardly and the tip fired as a fixed broadhead in jurisdictions where expandable broadheads are prohibited.
Applicant submits that, even in a well developed area of expertise, that his expandable broadhead arrow tip provides a unique and patentably distinct design from such art as will be better understood from a consideration of the accompanying drawings and disclosure.
