FIELD OF THE INVENTION
The invention relates to a stabilizer, and more specifically a stabilizer having three or more wires which can be adjustably tightened or loosened to control the stiffness, flex, spine and flex direction of the stabilizer.
BACKGROUND OF THE INVENTION
A stabilizer connected to an archery bow, by screwing it into a threaded accessory hole located just below the grip. Nearly all compound and Olympic recurve bows come from the factory with this accessory hole standard.
Stabilizers perform a variety of functions. They absorb vibrations in the bow at the shot, which reduces the shock felt in your hand on the bow grip, and makes the bow quieter. They help keep the bow balanced, by adding weight below the grip. That weight down low encourages the bow to stand up straight, which is critical for consistent accuracy. It also helps settle your sight as you aim at the target. Stabilizers combat bow torque or flex. When an archer releases the bowstring, the riser torques or flexes as all that energy hits it. But a stabilizer, which adds weight out in front of the bow, resists that torque.
BRIEF SUMMARY OF THE INVENTION
The inventive stabilizer controls the stiffness, spine, flex and flex direction of the bow. The archery stabilizer has a rod having first and second ends; first and second end caps connected to the first and second ends of the rod, and at least three stiffening members extending between the first and second end caps, each of the at least three stiffening members being constructed and arranged to selectively change the tension between the first and second end caps.
The rod is preferably a carbon fiber rod, but can be made of any material which provides suitable strength, such as metal or plastic. The rod has threaded ends to threadably engage with the end caps.
The archery stabilizer can have three or more stiffening members or wires, which can be made of wire or rope and are preferably coated in Kevlar.
By changing the length of the wires between the end caps, the stabilizer changes the load on the rod and therefore controls the stiffness, spine, flex and flex direction of the stabilizer.
The stabilizer can be attached to an archery bow, either to the front mount, the rear mount, in a V-bar arrangement or a side-bar arrangement, or any combination thereof.
The stabilizer can also have two or more supports spaced between the end caps, which aid in controlling the flex and flex direction of the stabilizer.

DETAILED DESCRIPTION OF THE INVENTION
While this invention may be embodied in many forms, there are described in detail herein specific embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.
For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.
FIG. 1 is a perspective view of a first embodiment of the invention, shown generally at 10. The stabilizer 10 has two end caps 12 and 14, connected by a carbon fiber rod 16, which has threaded ends and which mate with threaded openings in the end caps 12 and 14. Three Kevlar coated wires 18, 20 and 22 connected the end caps, which are spaced apart from each other and each wire can be selectively tightened or loosened to control the stiffness and flex of the rod 16. By selectively tightening or loosening the wires, you can change the flex, spine, and flex direction of the stabilizer to put different degrees of a load on the rod and also against each other. It should be understood that the invention could also be made with four, five or more wires, if desired.
The stabilizer works by adjusting the wires or cords (which these could be made of any wire or rope material) changing the load on center rod 16. By doing this you control the stiffness and direction of the flex of energy being caused by firing of the bow. The stabilizer design can work with 3 or more wires or cords. The more wires or cords the more adjustable the stabilizer is. The center rod material is carbon but can be any tube that has sufficient structural integrity to it, such as carbon fiber, metal of plastics.
Referring now to FIG. 2-4, FIG. 2 is a perspective view of the adjustable end of the stabilizer showing crimps 24 which connect the wires 18, 20 and 22 to hex heads 26, 28 and 30, which rotate independently of the crimps 24 to tighten or loosen the tension of wires 18, 20 and 22 between the two end caps 12 and 14. FIG. 3 shows that one end of the wires 18, 20 and 22 have threaded ends at 32. FIG. 4 shows that hex heads 26, 28 and 30 are connected to nuts 34, so that when a hex head is rotated, the wire 18, 20 or 22 is shortened or lengthened between end caps 12 and 14, thereby allowing selective control of the stiffness on rod 16, to control the flex, spine and flex direction of the stabilizer.
FIG. 5 shows the anchor end of the stabilizer. FIG. 6 shows the cable attached to the anchor end 36, which fit into the through holes of end cap 12.
FIG. 7 shows a quick disconnect 49 for attaching one or more stabilizers to an archery bow. Referring now to FIGS. 19-22, the quick disconnect is shown at 49, and a plate 50 is threadably attached to the stabilizer, and in turn is clamped in slot 52.
Referring now to FIGS. 8-14, FIG. 8 is a front view of a second embodiment of the invention, with two supports 38 spaced between the end caps. The supports help with the control of the flex, spine and flex direction of the stabilizer. FIG. 9 is a bottom view of the second embodiment. FIG. 10 is a perspective view of the second embodiment. FIG. 11 is a left view of the second embodiment. FIG. 12 is a right view of the second embodiment. FIG. 13 is a back view of the second embodiment. FIG. 14 is a top view of the second embodiment. FIG. 15 shows that the supports use a set screw to secure them to the carbon rod.
FIG. 16 shows a close up of the set screw 40 which is used to secure support 38 to the carbon fiber rod 16.
FIG. 17 shows a perspective view of the support 38.
FIG. 18 shows both supports 38 of the second embodiment.
FIG. 19 shows the quick disconnect unattached from a stabilizer.
FIG. 20 shows the quick disconnect partially attached to a stabilizer.
FIG. 21 shows the quick disconnect fully connected to a stabilizer.
FIG. 22 shows the threaded end of a stabilizer.
FIG. 23 shows a four wire embodiment of the inventive stabilizer.
FIG. 24 shows a five wire embodiment of the inventive stabilizer.
FIG. 25 shows a six wire embodiment of the inventive stabilizer.
FIG. 26 shows a stabilizer with a back bar setup, mounted to an archery bow.
FIG. 27 shows a sidebar setup.
FIG. 28 shows a sidebar setup from a different angle.
FIG. 29 shows a stabilizer setup with a v-bar.
The stabilizer can be attached to an archery bow (compound or recurve) in a number of arrangements. This can be used as a stabilizer rod on the front mount of a bow, a rear stabilizer and a back mount, a v bar set up and a side bar setup. These are all different locations you can mount the stabilizer on a bow.
