Archery Bow Stabilizer and Vibration Reducer

Abstract

A compound bow stabilizer removably attached to the bow riser consisting of a base unit, a tube body and weights. The base unit has an elongated slot for a bolt or stud adapted to be connected to the riser. The tube body assembly has one end removably attached to the base unit and a second end designed to accept an additional tube or weight. Additional weights are located along and around the inside of the tube body. The base unit utilizes a bolt or stud that mates with a threaded opening in the riser of the bow and can be offset relative to the threaded opening of the bow along the vertical and horizontal axes by sliding and rotating the base unit relative to the bolt to reduce undesired movement and vibration of the compound bow when an arrow is shot from the bow.

1 . An archery bow stabilizer and vibration reducer removably attachable to a stabilizer attachment fitting on a compound bow, said compound bow stabilizer comprising:
 a base unit having an elongated slot for receiving a bolt or stud adapted to be connected to a riser of a compound bow;   a tube body adjustable to at least three separate lengths having a first end and a second end, said first end adapted to be coupled to said base unit, second end adaptable with female or male ends;   a weight adapted to be located within said tube body;   whereby said bolt or stud in said base unit is adapted to be threaded into a threaded opening in a riser of the compound bow where said base unit can be offset relative to the threaded opening of the compound bow along the vertical and horizontal axis by sliding said base unit relative to the bolt and rotating said base unit relative to said bolt; whereby undesired movement in the bow is reduced both while aiming and during the shot.   
   
   
       2 . The archery bow stabilizer and vibration reducer of  claim 1  wherein said tube body has at least one longitudinal slot for receiving said weight. 
   
   
       3 . The archery bow stabilizer and vibration reducer of  claim 2  wherein adjustment of said archery bow stabilizer is obtained by positioning at least one weight inside the tube body along a longitudinal slot. 
   
   
       4 . The archery bow stabilizer and vibration reducer of  claim 3  wherein said weight has attachment means for removably attaching the weight along a longitudinal slot to the inside surface of the tube body from outside the tube body. 
   
   
       5 . The archery bow stabilizer and vibration reducer of  claim 4  wherein said attachment means is a threaded bolt or other attachment device which can be slidably received by a longitudinal slot that holds the weight at a desired position along the longitudinal slot in the tube body when tightened. 
   
   
       6 . The archery bow stabilizer and vibration reducer of  claim 5  wherein a backing member may be positioned between the weight and the inside surface of the tube body allowing the weight to oscillate and absorb vibrations when an arrow is shot. 
   
   
       7 . The archery bow stabilizer and vibration reducer of  claim 6  wherein said backing member is a yieldable member such as rubber or other types of elastoners. 
   
   
       8 . The archery bow stabilizer and vibration reducer of  claim 4  wherein said weight is a half cylinder having a diameter which is substantially equal to the inside diameter of the tube body as well as other shapes which concentrate their mass away from the center axis of the stabilizer and towards the outer circumference of the tube bodies. 
   
   
       9 . The archery bow stabilizer and vibration reducer of  claim 5  wherein the base unit has a cylindrical body and the tube body is slidably coupled to the cylindrical body of the base unit. 
   
   
       10 . The archery bow stabilizer and vibration reducer of  claim 9  wherein O rings may be located between the cylindrical body of the base unit and the tube body. 
   
   
       11 . The archery bow stabilizer and vibration reducer of  claim 5  wherein the second end of the tube body may have a weight attached. 
   
   
       12 . The archery bow stabilizer and vibration reducer of  claim 11  wherein said second end of said tube body is slidably coupled to the end weight and may be separated from said weight with O rings. 
   
   
       13 . The archery bow stabilizer and vibration reducer of  claim 12  wherein the tube body has at least one slot allowing weights to be placed longitudinally and axialy along and around the inside surface of the tube body. 
   
   
       14 . The archery bow stabilizer and vibration reducer of  claim 1  wherein the base unit is made of metal such as aluminum or steel, carbon, plastic, or other materials commonly found in the industry. 
   
   
       15 . The archery bow stabilizer and vibration reducer of  claim 1  wherein the weight is composed of a material such as lead, stainless steel, aluminum, titanium or other similar materials. 
   
   
       16 . The archery bow stabilizer and vibration reducer of  claim 1  wherein the tube body is made of aluminum, steel or other materials commonly found in the industry. 
   
   
       17 . The archery bow stabilizer and vibration reducer of  claim 1  wherein the elongated slot in said base unit is recessed. 
   
   
       18 . The archery bow stabilizer and vibration reducer of  claim 1  wherein said first end of tube body has a slot which may include a depression or recess at or near the end of the slot to allow a knob, bolt, or other mounting device to seat properly as well as acting as a safety catch in the event the knob, bolt or other securing device is not properly tightened or happens to work loose.
