ARROW QUIVER ASSEMBLY AND FRAME
A frame is provided, and a quiver assembly is attached to the frame. The frame, preferably made from aluminum, is manufactured by using an axis of extrusion that is perpendicular to the primary axis of the quiver assembly. A top portion of the quiver assembly provides blade covers with foam inserts to store, for example, expandable broadheads. The blade covers are non-circular in shape, so that broadheads can be rotated approximately ninety degrees to a secure position. The quiver also utilizes a set screw that allows a the hunter to adjust the camming force required for loading and unloading the quiver from the bow. The quiver assembly utilizes rubber posts that allow for a quiet operation, as well as a secure means of locking the quiver assembly to a bow.
This application is a divisional, and claims the benefit under 35 U.S.C. §120, of U.S. patent application Ser. No. 13/736,694, filed Jan. 8, 2013, which claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/584,433, filed Jan. 9, 2012, each of which is herein incorporated by reference in its entirety.
FIELD OF THE INVENTIONEmbodiments of the present invention generally relate to arrow quiver assemblies and frames for archery. One or more embodiments of the quiver assembly has particularly advantageous blade covers, and utilizes a camming force to load and unload the quiver from the bow as well as particular techniques to manufacture the quiver frame.
BACKGROUND OF THE INVENTIONOne of the issues with expandable broadheads is that they can potentially rattle while in the quiver, or possibly allow the blades to predeploy while in the quiver. In order to address this concern, in one or more embodiments of the present invention, a quiver holds the blades of an expandable broadhead in the retracted and locked position. This is accomplished by providing foam inserts in the hood of the quiver that are an oval (or, more generally, a non-round) in shape. The arrow is inserted into the hood with the blades in line with the major axis of the opening in the foam. After insertion, the arrow is then rotated, which causes the foam to exert inward pressure on the blades, therefore stabilizing them to keep them from rattling or pre-deploying.
Another issue with known quiver assemblies is that they do not provide the user with the ability to adjust the camming force required for loading and unloading the quiver from the bow. One or more embodiments of the present invention advantageously provide the user with the ability to set a desired force that is required for loading and unloading the quiver from the bow.
Yet another problem with the manufacture of quiver frames is material waste and attendant increased cost. I have discovered a way to more cost-effectively manufacture quiver frames by utilizing an axis of extrusion that is perpendicular to the primary axis of the quiver assembly.
SUMMARY OF THE INVENTIONA frame is provided, and a quiver assembly is attached to the frame. The frame, preferably made from aluminum, is manufactured by using an axis of extrusion that is perpendicular to the primary axis of the quiver assembly. A top portion of the quiver assembly provides blade covers with foam inserts to store, for example, expandable broadheads. The blade covers have a non-round (e.g., oval) shape, so that broadheads can be rotated approximately ninety degrees to a secure position. The quiver assembly also utilizes a set screw that allows a hunter to adjust the camming force required for loading and unloading the quiver assembly from the bow. The quiver assembly utilizes rubber posts that allow for a quiet operation, as well as a secure means of locking the quiver assembly to a bow.
In one embodiment, a frame adapted for use with a quiver assembly is provided for holding and securing arrows. The frame includes: i) a horizontal top surface extending in a direction of a first axis; ii) a horizontal bottom surface extending in the direction of the first axis; iii) a first curved side surface with three points of inflection, wherein end points of the first curved surface contact a first endpoint of the horizontal top surface and a first endpoint of the horizontal bottom surface, wherein the first curved side extends in a direction of a second axis that is substantially perpendicular to the first axis; iv) a second curved side surface with three points of inflection, wherein end points of the second curved surface contact a second endpoint of the horizontal top surface and a second endpoint of the horizontal bottom surface, wherein the second curved side extends in the direction of the second axis; v) a horizontal surface positioned approximately midway between the horizontal top surface and the horizontal bottom surface, the horizontal surface having a first endpoint that contacts the first curved side surface and a second endpoint that contacts the second curved side surface; vi) a first curved surface extending in the direction of the first axis, having one point of inflection, and having respective endpoints contacting the first curved side surface and the second curved side surface; vii) a second curved surface extending in the direction of the first axis, having one point of inflection, and having respective endpoints contacting the first curved side surface and the second curved side surface, wherein the second curved surface is positioned between the horizontal bottom surface and the first curved surface.
In another aspect of the invention, the frame is manufactured by using an axis of extrusion that is substantially perpendicular to a plane formed by the first axis and the second axis.
The blades are initially in line with the major axis of the opening of an insert 104. After the blade (on the arrow) is placed in the insert 104, the arrow is then rotated approximately 90 degrees, which causes the insert 104 to exert inward pressure on the blades, therefore stabilizing them to keep them from rattling or pre-deploying.
A top arrow shaft holder 102 is provided. The top arrow shaft holder 102 is secured to the quiver frame 100 by placing a plate 110 in an opening (not shown) on the underside of the arrow shaft holder 102, and securing the top arrow shaft holder 102 and plate 110 to the quiver frame 100 using screws 116. In one or more embodiments, top arrow shaft holder 102 is manufactured by placing the plate 110, which is preferably made from aluminum, in an injection mold, and having rubber injection molded around the plate 110.
Similarly, the bottom arrow shaft holder 126 is secured to the quiver frame 100 by placing a plate 112 in an opening (not shown) on the underside of the bottom arrow shaft holder 126, and securing the bottom arrow shaft holder 126 and plate 112 to the quiver frame 100 using screws 122. Top arrow shaft holder 102 and bottom arrow shaft holder 126 are preferably made from a compliant material, such as rubber, to facilitate insertion and removal of arrows from the arrow holding grooves 128a-e in top arrow shaft holder 102, and grooves 130a-e in bottom arrow shaft holder 126. In a preferred embodiment, the rubber can be a thermoplastic elastomer or TPE, such as Dynaflex G7980-9001-02, Shore A-80, Black, 0% regrind.
The housing 108 is preferably secured to the hood 106 using screws 124, and the hood 106 is preferably secured to the frame using screws 114.
The rubber mounting posts 118a, 118b for the quiver are preferably a compliant material, which advantageously provides for a more secure and quieter operation of adapting the quiver frame 100 and quiver assembly 101 to the bow (not shown), as will be described herein. Posts 118a, 118b can optionally be made as a single, integrated piece or unit. In one or more embodiments, the compliant material is a thermoplastic elastomer TPE, which can be injection molded, such as Dynaflex 7990-9001-02, 0% regrind, Shore A-90, Black. The compliant posts 118a, 118b allow the posts 118a, 118b to deform during the camming that is used to adapt the quiver frame 100 and quiver assembly 101 to a bow (not shown). The posts 118a, 118b are secured to the quiver frame 100, preferably using a pin 120. When posts 118a, 118b are made from a compliant material, they also advantageously provide for vibration damping in the bow assembly during a shooting operation.
In order to rotate the quiver assembly 101 and quiver frame 100 into the locked position as shown in
Extruded material emerges as an elongated piece, such as a quiver frame cross-section 1102, with the same profile as the die opening 1008. The exit temperature of the extruded profile will be on the order of 950 degrees Fahrenheit. The extruded material is then cooled at an appropriate speed, and heat treated in accordance with known techniques to achieve the final desired material properties.
One or more embodiments of the present invention advantageously utilizes an extrusion process, and thereby produces relatively little material waste as compared, for example, to a machining process, in which there is substantial material waste, or casting, in which the die costs can be expensive and the material properties are not generally as good as those provided by an extrusion process. This extrusion method of providing quiver frame cross-section 1102 creates the near net shape profile, which can then be very quickly and readily cut to length and finished. In contrast, known manufacturing methods, techniques and processes result in significantly greater material waste and processing time as the frame shape must be cut from a large rectangular piece of stock material, resulting in elevated costs and time.
