Publication number: 20090145411Abstract: Quiet, lightweight, well-balanced, forgiving, and accurate compound archery bows which have significantly reduced vibration and bow jump. The limbs and cams of these bows can be removed and replaced without a bow press, and the limbs of the bows are functional (active) over essentially their entire length and allow one to obtain equivalent performance from a more compact and lighter bow. The bow limbs may be leverage locked in articulated limb pockets. The limb butts extend forward well beyond the front of the riser. This eliminates limb length and limb angle as major factors in determining brace height, allowing one to choose a riser style and limb length which optimize arrow speed and bow stabilization. Novel adjustment mechanisms allow one to easily adjust the poundage or poundage and brace height of the bow. Vibration isolation systems may be employed to isolate the bow riser from the limb pockets.Type: ApplicationFiled: October 9, 2008Publication date: June 11, 2009Inventors: Steven C.

Patent number: 7201161Abstract: A compound spring-loaded archery bow, which retains the appearance of a traditional bow, has a rigid bow frame that is formed by a central riser with a handgrip and arrow rest, an upper limb extending upward from the central riser and a lower limb extending downward from the central riser. Cam mechanisms are mounted at the upper end of the upper limb and the lower end of the lower limb and a bowstring is secured to and extends between the upper and lower cam mechanisms. When the bowstring is drawn from an initial preset position to shoot an arrow, there is a synchronized actuation of the upper and lower cam mechanisms. The upper and lower limbs are tubular and contain separate upper and lower spring assemblies for applying tension to the bowstring through the cam mechanisms only when the bowstring is drawn from its initial preset position.Type: GrantFiled: July 18, 2005Date of Patent: April 10, 2007Inventor: Merineth S.

Patent number: 7163183Abstract: A bow holder for holding an archery bow when the bow is not being used while hunting. This base can be used on multiple type tree stands either vertically or horizontally depending on the tree stand used. The connection between the main base parts and wire holder allows a 360-degree pivot of the holder, which makes the bow more accessible for the hunter. The holder secures the bow from falling or being knocked off or out of its holder, but the bow holder also allows the bow to be easily taken by the hunter by simply tilting the bow toward the hunter and lifting the bow out of the holder.Type: GrantFiled: January 19, 2005Date of Patent: January 16, 2007Assignee: Inspired and Created Concepts, LLCInventors: Warren E. Sutherland, Roy G. Mollette

Patent number: 7152595Abstract: An archer must have some strength to both pull a bowstring and hold the archery bow in position. Disclosed is an aid to archers who wish to relieve the arm holding the bow in position. A bow brace extending between the archery bow and the archer transmits the force of the drawn bowstring to the archer's torso instead of to his or her arm. The bow brace is affixed to the archery bow and includes a pad at the end engaging the archer's torso. The bow brace may be removable or foldable for transport and storage.Type: GrantFiled: December 2, 2004Date of Patent: December 26, 2006Inventor: Anthony J. Muhich

Patent number: 7077116Abstract: An archery bow limb attachment construction includes a limb bolt washer having a flat undersurface opposed to an outer surface on the limb, a leg extending from the undersurface into a non-round opening in the limb to prevent rotation of the limb bolt washer with respect to the limb, a through-opening having a cylindrical countersink at an end opposed to the undersurface, and an internally threaded lateral opening communicating with the through-opening between the countersink and the undersurface. An annular bearing washer has a cylindrical outer periphery received in the countersink of the limb bolt washer, and a through-opening having a conical countersink remote from the limb bolt washer. A cap screw has a head received in the conical countersink of the bearing washer and an externally threaded shank that extends through the bearing washer, the limb bolt washer and the archery bow limb into an internally threaded opening in an archery bow handle riser.Type: GrantFiled: December 9, 2004Date of Patent: July 18, 2006Inventor: Rex F. Darlington

Patent number: 7066165Abstract: A bow includes a bow frame with a geometric center, and a window surrounding the geometric center. A bow handle is attached to the bow frame at a position offset from the geometric center, such that a user can fire an arrow through the window, through the geometric center of the bow. A gimbal may be disposed within the window, the bow handle being pivotally attached to the gimbal, so as to allow free pivoting of the bow about two substantially orthogonal axes.Type: GrantFiled: August 18, 2004Date of Patent: June 27, 2006Inventor: Kent M. Perry

Patent number: 7025051Abstract: Certain preferred embodiments of the present invention use a dual constraint system to align an archery bow limb with a limb cup on a riser. Preferably the limb is aligned so that the centerline of the limb is aligned with the centerline of the riser. The plane of the limb is also constrained to facilitate this centerline alignment and to prevent excessive clearance between the limb, limb pocket and corresponding riser. In certain preferred embodiments, the present invention uses taper or wedge geometry in both the X-Y and X-Z planes along the length and separately along the depth of the limb cup engagement with the archery bow limb. Preferably this provides two complimentary locking mechanisms between the limb and limb cup.Type: GrantFiled: November 9, 2004Date of Patent: April 11, 2006Assignee: SOP Services, Inc.Inventor: Henry M. Gallops, Jr.
