## CPC

- F41B 5/1426: {Bow stabilisers or vibration dampers}
- F41B: WEAPONS FOR PROJECTING MISSILES WITHOUT USE OF EXPLOSIVE OR COMBUSTIBLE PROPELLANT CHARGE; WEAPONS NOT OTHERWISE PROVIDED FOR (projectiles for fishing, e.g. fish-spears, A01K81/00; sports implements for throwing A63B65/00, e.g. boomerangs A63B65/08; stationary apparatus for projecting sports balls, e.g. tennis balls, A63B69/40; throwing or slinging toys A63H33/18; knives, axes B26B; projectiles or missiles other than those incorporating springs as projecting means F42B6/00)

## Abstract

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.

## Claims

### Claim 1

An archery stabilizer comprising:
a rod having first and second ends;
first and second end caps connected to the first and second ends of the rod;
at least three stiffening members extending between the first and second end caps, and spaced apart from each other, and each of the at least three stiffening members being constructed and arranged to selectively change a tension between the first and second end caps.

### Claim 2 (depends on 1)

The archery stabilizer of claim 1 wherein the rod has threaded ends and the first and second end caps have mating threaded openings which can be threadably attached to the rod.

### Claim 3 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members are Kevlar coated wires.

### Claim 4 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members are Kevlar coated rope.

### Claim 5 (depends on 3)

The archery stabilizer of claim 3 wherein an anchor end of the wire is connected to one of the first or second end caps, and an other end of the wire has a threaded end which is threadably connected to a nut and hex head connected to the other of the first and second end caps, so allow each wire to be adjusted to change a length of the wire between the first and second end caps, which changes a load on the rod, which in turn controls a stiffness and direction of the flex of energy caused by firing an archery bow.

### Claim 6 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members is comprised of three wires.

### Claim 7 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members is comprised of four wires.

### Claim 8 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members is comprised of five wires.

### Claim 9 (depends on 1)

The archery stabilizer of claim 1 wherein the at least three stiffening members is comprised of six wires.

### Claim 10 (depends on 1)

The archery stabilizer of claim 1 in combination with an archery bow.

### Claim 11 (depends on 1)

The archery stabilizer of claim 1 in combination with an archery bow, with the stabilizer connected to a front mount of the bow.

### Claim 12 (depends on 1)

The archery stabilizer of claim 1 in combination with an archery bow, with the stabilizer connected to a rear mount of the bow.

### Claim 13 (depends on 1)

Two archery stabilizers of claim 1 in combination with an archery bow, with the stabilizers connected to the archery bow in a V-bar arrangement.

### Claim 14 (depends on 1)

Two archery stabilizers of claim 1 in combination with an archery bow, with the stabilizers connected to the archery bow in a side-bar arrangement.

### Claim 15 (depends on 1)

The archery stabilizer of claim 1 further including a pair of supports positioned between the end caps.

### Claim 16 (depends on 2)

The archery stabilizer of claim 2 wherein the rod is a carbon fiber rod.
