Abstract
Abstract An archery bow stabilizer is disclosed. A stabilizing weight element is supported on a first end of a support rod. A second end of the support rod is attached to a damper which is at least partially embedded in a centrally located handle of an archery bow. The damper has its center of gravity located within the area of the handle and includes means for resiliently supporting the second end of the support rod whereby the damper is permitted to follow minor vibrations in the bow substantially independently of the stabilizing effect of the weight element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
Apparatus comprising: an archery bow having a centrally located handle, said handle having an outer periphery; a stabilizing weight element; a damper at least partially embedded in said handle of said bow and having its center of gravity located adjacent the longitudinal axis of the bow and positioned within the boundary of said outer periphery of said handle at the immediately adjacent area of attachment of the damper to the handle, said damper including a recess therein; a support rod supporting said stabilizing weight element on one end thereof, the remaining end of said support rod being located within said recess to said damper and an elastic sleeve located in said recess between the walls of the recess of said damper and said other end of said support rod and at least partially within the boundary of said outer periphery of said handle, said elastic sleeve adapted to resiliently couple said support rod to said damper in such a manner that said bow is permitted to follow minor oscillations in an arrow shot by said bow substantially independently of the stabilizing effect of said weight element.
Claim 2
Dependent Claim
186 words
Apparatus comprising: an archery bow having a centrally located handle, said handle having an outer periphery; a stabilizing weight element; a damper at least partially embedded in said handle of said bow and having its center of gravity located adjacent the longitudinal axis of the bow and positioned within the boundary of said outer periphery of said handle at the immediately adjacent area of attachment of the damper to the handle, said damper including a recess therein; a support rod supporting said stabilizing weight element on one end thereof, the remaining end of said support rod being located within said recess to said damper and an elastic sleeve located in said recess between the walls of the recess of said damper and said other end of said support rod and at least partially within the boundary of said outer periphery of said handle, said elastic sleeve adapted to resiliently couple said support rod to said damper in such a manner that said bow is permitted to follow minor oscillations in an arrow shot by said bow substantially independently of the stabilizing effect of said weight element.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 in which said damper is fully embedded within said boundary of said outer periphery of said handle.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 in which said damper is attached to said handle by a screw engagement.
Claim 5
Dependent Claim
162 words
The apparatus of claim 1 further comprising: an additional stabilizing weight element; an additional damper at least partially embedded in said handle of said bow and having its center of gravity located within the boundary of said outer periphery of said handle, said damper including a recess therein; an additional support rod supporting said additional stabilizing weight element on one end thereof, the remaining end of said support rod being located within said recess of said damper; an additional elastic sleeve located in said recess of said additional damper between the walls of said additional damper and said remaining end of said additional support rod and at least partially within the boundary of said outer periphery of said handle, said additional elastic sleeve adapted to resiliently couple said additional support rod to said additional damper whereby said bow is permitted to follow minor oscillations in an arrow shot by said bow substantially independently of the stabilizing effect of said additional weight element.
Claim 6
Dependent Claim
22 words
The apparatus of claim 4, wherein each of dampers are fully embedded within said boundary of said outer periphery of said handle.
Claim 7
Dependent Claim
20 words
The apparatus of claim 5 in which said dampers are each attached to said handle by a respective screw engagement.
Claim 8
Dependent Claim
21 words
The apparatus of claim 4, wherein the resiliently supporting means of each of said dampers includes an elastic sleeve embedded therein.
