Description
Background of the Invention
[0001] 1. Field of the Invention
[0002] The present invention relates to arrowhead sleeves and more particularly pertains to a new arrowhead sleeve for encasing a broad head to protect the broad head during storage and transport.
[0003] 2. Description of the Prior Art
[0004] The use of arrowhead sleeves is known in the prior art. The prior art commonly teaches a sleeve that is slid over an arrowhead to encase the arrowhead.
[0005] While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that has certain improved features that encase a broad head attached to an arrow shaft and are secured around the broad head to inhibit removal of the device from the broad head. Additionally, the device can be equipped with weep holes to allow liquid on the broad head to drain away to limit corrosion of the broad head by the liquid.
Summary of the Invention
[0006] The present invention meets the needs presented above by generally comprising a pair of clamshell portions being positionable around the broad head to enclose the broad head between the clamshell portions. The clamshell portions inhibit contact with the broad head when the clamshell portions are positioned around the broad head. One of the clamshell portions is hingedly coupled to the other one of the clamshell portions to permit pivoting of the clamshell portions between a closed position and an open position. A latching assembly includes a first mating portion and a second mating portion. The first mating portion is coupled to one of the clamshell portions and the second mating portion is coupled to the other one of the clamshell portions. The first mating portion mates with the second mating portion to releasably secure the clamshell portions in the closed position.
[0007] There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
[0008] The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

Description of the Preferred Embodiment
[0016] With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new arrowhead sleeve embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
[0017] As best illustrated in FIGS. 1 through 6 , the broad head 1 cover device 10 generally comprises a pair of clamshell portions 12 being positionable around a broad head 1 to enclose the broad head 1 between the clamshell portions 12. The clamshell portions 12 inhibit contact with the broad head 1 when the clamshell portions 12 are positioned around the broad head 1. One of the clamshell portions 12 is hingedly coupled to the other one of the clamshell portions 12 to permit pivoting of the clamshell portions 12 between a closed position and an open position.
[0018] Each of the clamshell portions 12 includes a head portion 14 for receiving a portion of the broad head 1. The head portion 14 of each of the clamshell portions 12 is substantially cone shaped when the clamshell portions 12 are in a closed position. The head portion 14 has a plurality of knockouts 16 positioned in the head portion 14. Each of the knockouts 16 is removable from the head portion 14 to expose one of a plurality of weep holes 18 extending into the head portion 14. Each of the weep holes 18 permits liquid on the broad head 1 to drain from the clamshell portions 12. A shaft sleeve 20 is integrally coupled to a base edge 22 of the head portion 14. The shaft sleeve 20 receives a portion of an arrow shaft 2 when the clamshell portions 12 are closed around the broad head 1. The shaft sleeve 20 has a substantially semi-cylindrical shape.
[0019] Each of the clamshell portions 12 also includes a liner 24 coupled to an interior surface 26 of the shaft sleeve 20. The liner 24 abuts the arrow shaft 2 to inhibit sliding of the clamshell portions 12 along the arrow shaft 2 when the clamshell portions 12 are positioned around the broad head 1. The liner 24 is comprised of a resiliently compressible material to accommodate arrow shafts 2 of varying diameters and to increase friction between the liner 24 and the arrow shaft 2.
[0020] A latching assembly 28 includes a first mating portion 30 and a second mating portion 32. The first mating portion 30 is coupled to one of the clamshell portions 12 and the second mating portion 32 is coupled to the other one of the clamshell portions 12. The first mating portion 30 mates with the second mating portion 32 to releasably secure the clamshell portions 12 in the closed position. The first mating portion 30 includes a lip 34 extending outwardly from a free edge 36 of the head portion 14 of the associated one of the clamshell portions 12. The first mating portion 30 includes a pair of leverage tabs 38 coupled to the free edge 36 of the head portion 14 on opposing sides of the lip 34.
[0021] The second mating portion 32 includes a latch tab 40 coupled to the free edge 36 of the head portion 14 of the associated one of the clamshell portions 12. The latch tab 40 is extendable over the lip 34 of the second mating portion 32 to releasably secure the clamshell portions 12 in the closed portion. The latch tab 40 is positioned between the leverage tabs 38 when the clamshell portions 12 are in the closed position.
[0022] In an embodiment, as shown in FIGS. 1 through 4 , each of a plurality of alignment pins 42 is coupled to the interior surface 26 of one of the clamshell portions 12. Each of a plurality of alignment sleeves 44 is coupled to the interior surface 26 the other one of the clamshell portions 12. Each of the alignment sleeves 44 receives one of the alignment pins 42 to maintain alignment of the clamshell portions 12 when the clamshell portions 12 are in the closed position. The alignment pins 42 are positioned adjacent to the free edge 36 of the head portion 14 and positioned opposite the first mating portion 30. The alignment sleeves 44 are positioned adjacent the free edge 36 of the head portion 14 of the other one of the clamshell portions 12 and positioned opposite the second mating portion 32.
[0023] In an embodiment, as shown in FIG. 6 , the second mating portion 32 includes a pair of flanking tabs 46 coupled to the free edge 36 of the associate one of the clamshell portions 12. The flanking tabs 46 are positioned on opposing sides of the latch tab 40. The flanging tabs 46 are aligned with the leverage tabs 38 when the clamshell portions 12 are in the closed position. Each of the leverage tabs 38 has at least one alignment pin 42 extending outwardly from the associated one of the leverage tabs 38. Each of the flanking tabs 46 has at least one alignment aperture 48 extending into the associated one of the flanking tabs 46. The at least one alignment pin 42 of each of the leverage tabs 38 is inserted into the at least one alignment aperture 48 of an aligned and associated one of the flanking tabs 46 to maintain alignment of the clamshell portions 12 in the closed position.
[0024] In use, the broad head 1 is positioned in the head portion 14 of one of the clamshell portions 12 with arrow shaft 2 positioned in the shaft sleeve 20 of the associated one of the clamshell portions 12. The other one of the clamshell portions 12 is pivoted over the broad head 1 to enclose the broad head 1 in the head portion 14 of the clamshell portions 12. The first mating portion 30 and the second mating portion 32 are releasably mated to secure the clamshell portions 12 in the close position.
[0025] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
[0026] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
