ABSTRACT:
SPONSORSHIP
This invention is not made under any Federally related nor Independent Sponsorship and is the result of the efforts of the sole inventor.
RELATED APPLICATIONS
Applicant has no and is not aware of any pending applications by others which relate to this application or the invention disclosed herein.
FIELD OF THE INVENTION
This invention relates generally to broadhead arrows and more specifically to broadhead arrows which include a primary body portion and a blade carrying section which blade carrying section is removable from the primary body portion for either replacement of dulled blades or for changing the style of blade being used by the user. The first style of selectable blades include expandable blades which are maintained in a folded, in-flight position and which expand to an increased cutting dimension upon the broadhead striking a target surface. A second style of blades includes a stationary blade or blades of a constant cutting dimension. In either selection, the blade carrying section is prevented from rotating relative to the primary body portion during flight and when striking and entering the target.
SHORT SUMMARY OF THE INVENTION
A broadhead arrow having a primary body portion which is attachable to the front of an arrow shaft and a blade carrying section which is removable from the primary body portion when the primary body portion is removed from the arrow shaft. Thereafter the blade carrying section is replaceable to allow the user to replace the same, as a unit, with sharp blades or to select a new blade carrying section which has blades of a different style than that previously used.
The penetrating, forward end of the primary body may be either conically tapered or may include cutting edges. Either type of penetrating end may be integral with the primary body or may be attached thereto.
The blade carrying section is prevented from rotation with respect to the main body portion during in-flight and target string conditions.
At least two styles of blades which are of most common usage are disclosed herein.
The first style is of the expandable type wherein the blades carried by the blade carrying section are pivotally mounted thereon to provide a reduced, in-flight, dimension and wherein the blades pivot upon striking a target to expose the cutting surfaces thereof and provide a cutting surface of greater dimension than that of the in-flight dimension.
The second style is referred to as a stationary blade wherein the blades are not moveable and remain in a single position with the cutting edge thereof being constant dimension and continually exposed. These blades may be vented.
PRIOR ART
The known prior art does not disclose a broadhead arrow having two distinct, separable sections, one section forming a primary body portion with the second section providing a blade carrying section with the selected style blades of the broadhead being carried thereby. Such a structure allows for replacement of blades with either sharp blades of the same style or a blade style and configuration which differs from the first style being used.
OBJECTS AND ADVANTAGES OF THE INVENTION
The style of broadhead used in hunting varies from individual to individual and is often governed by various district laws.
Certain hunters prefer a broadhead which expands upon striking a target but which has a relatively small diameter while in the in-flight position. Other hunters prefer a non-expandable broadhead which has exposed blades of a constant effective cutting diameter during flight and upon striking the target.
To this time it has been necessary for an archer to select one or the other style for use or to carry two distinct styles for use at his or her option.
With applicant's invention, a relatively simple, but heretofore unused concept is provided. This is the utilization of a blade carrying section of the broadhead to be removable from and replaceable upon a major body portion of the broadhead with the blade carrying portion providing the blade selection.
It is therefore an object of the applicant's invention to provide a broadhead for attachment to an arrow shaft which provides at least two distinct elements, these being a main body portion having a forward penetrating end and a rearward shaft attachment section with a blade carrying section receivable on the rearward shaft attachment section of the main body portion.
It is a further object of the applicant's invention to provide a broadhead which includes a main body portion and a blade carrying section with the blade carrying section provided with blades of distinct style for interchanging of blade styles at the option of the archer.
It is a further object of the applicant's invention to provide a broadhead which includes a main body portion and blade carrying section with a first style of blades of the blade carrying section being forwardly foldable for in-flight travel and pivoting upon the blade carry section to a rearward, open position thus providing an enlarged, effective, cutting diameter.
It is a further object of the applicant's invention to provide a broadhead which includes a main body portion and a blade carrying section with the blade carrying section provided with at least a second style of blade consisting of two or more stationary blades with exposed cutting surfaces of a preselected constant cutting diameter.
It is still a further object of the applicant's invention to provide a broadhead which includes a main body portion and a separable blade carrying section with means provided between such portion and section to prevent relative rotation therebetween during flight or upon striking the intended target.
It is yet a further object of the applicant's invention to provide a broadhead which includes a penetrating tip which is integral or attachable to the main body portion thereof
These and other objects and advantages of the applicant's invention will more fully appear from a consideration of the accompanying drawings and disclosure.
