ARROW SYSTEM

Abstract

A arrow system embodying a glue-in configuration or screw-over configuration of broadhead to arrow shaft connection is provided. The glue-in configuration provides an externally threadless broadhead shank for slidably reception into the complementary and cross-sectionally coextensive lumen of the arrow shaft. The screw-over configuration provides a broadhead with female internal threading that operatively associates with male threading of an insert that interconnects the broadhead to the lumen of the arrow shaft.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0031] Broadly, an embodiment of the present invention provides an arrow system embodying a glue-in configuration or screw-over configuration of broadhead to arrow shaft connection. The glue-in configuration provides an externally threadless broadhead shank for slidably reception into the complementary and cross-sectionally coextensive lumen of the arrow shaft. The screw-over configuration provides a broadhead with female internal threading that operatively associates with male threading of an insert that interconnects the broadhead to the lumen of the arrow shaft.

[0032] Referring to FIGS. 2A through 4D, the present invention provides arrow systems adapted to optimize concentricity between broadhead 10 and arrow shaft 30 through improvements in the broadhead-arrow shaft interface. The broadhead-arrow shaft interface may be a glue-in configuration and, in another embodiment, may be a screw-over configuration.

[0033] Referring to FIGS. 2A and 2B, the glue-in configuration includes broadhead 10 with an externally threadless shank 12. The externally threadless shank 12 may provide a uniform cross-section throughout its operable length (i.e., the length of the externally threadless shank 12 that interfaces with the arrow shaft 30). The externally threadless shank 12 may extend between one-half to one and one-half of an inch. The arrow shaft 30 is tubular, wherein the inner circumference or periphery of the lumen 32 of the arrow shaft 30 has a uniform cross section approximately coextensive with the external cross section of the threadless shank 12, facilitating a snug reception. Adhesive may be applied along the outer surface of the threadless shank 12, thereby further ensuring a tight, secure fitment between the threadless shank 12 and the inner circumference of the arrow shaft 30.

[0034] The externally threadless shank 12 may have internal threading for selectively receiving the threaded weights 14, as illustrated in FIG. 2B. The glue-in configuration may include an optional intermediate collar 20 into which the externally threadless shank 12 is slid, as opposed to the lumen 32 of the arrow shaft 30. The opposing end of the collar 20 may slide over the arrow shaft 30. Again, the collar 20 is optional as the glue-in configuration can directly connect the broadhead shank into the lumen on the arrow shaft 30.

[0035] Referring to FIGS. 3A through 3C, the screw-over configuration includes a broadhead 40, an insert 50 and an arrow shaft 60. The broadhead 40 has an open proximal end 48 that communicates with a hollow having internal female threading along an inner circumference thereof. A distal end 52 of the insert 50 has external male threading complementary of the internal female threading of the open proximal end 48 of the broadhead 40. The proximal portion 58 of the insert 50 has internal threading for selectively receiving threaded weights 14. The proximal portion 58 is dimensioned and adapted to be slidably received in the inner circumference of the arrow shaft 60, thereby affording the advantages of eliminating a collar as well as enabling a snug fitment that promotes concentricity.

[0036] The screw-over configuration, with the female threading of the open proximal end 48, facilitates clocking of the broadhead blades 42 relative to the vanes 62 of the arrow shaft 60 in a repeatably manner irrespective of the size and shape of the remaining portion of the broadhead 40. Thereby enabling inherent modularity of different types and styles of broadheads blades 42 to the same insert 50, thus the ability of the end user to readily and repeatedly transition among a plurality of target point configurations for different situations.

[0037] As used in this application, the term “about” or “approximately” refers to a range of values within plus or minus 10% of the specified number. And the term “substantially” refers to up to 90% or more of an entirety. Recitation of ranges of values herein are not intended to be limiting, referring instead individually to any and all values falling within the range, unless otherwise indicated, and each separate value within such a range is incorporated into the specification as if it were individually recited herein. The words “about,” “approximately,” or the like, when accompanying a numerical value, are to be construed as indicating a deviation as would be appreciated by one of ordinary skill in the art to operate satisfactorily for an intended purpose. Ranges of values and/or numeric values are provided herein as examples only, and do not constitute a limitation on the scope of the described embodiments. The use of any and all examples, or exemplary language (“e.g.,” “such as,” or the like) provided herein, is intended merely to better illuminate the embodiments and does not pose a limitation on the scope of the embodiments or the claims. No language in the specification should be construed as indicating any unclaimed element as essential to the practice of the disclosed embodiments.

[0038] In the following description, it is understood that terms such as “first,” “second,” “top,” “bottom,” “up,” “down,” and the like, are words of convenience and are not to be construed as limiting terms unless specifically stated to the contrary.

[0039] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
