Abstract
Abstract An archery bow being provided with at least one pair of stabilizers or vibration dampeness each of which comprises a vibrator, such as a rod- member with a weight mounted at the free end thereof. The vibrator extends over the limb section of the archery bow, and is directly connected to the limb section through an elastic member, such as a coil spring. The vibrator is also connected to the bow at another location on the bow. The shock and vibration caused by the limb section is directly and immediately transmitted to the vibrator through the elastic member, and is effectively absorbed by the vibrator. The elastic member prevents the shock or vibration that is once transmitted from the limb section to the vibrator to be fed back to the limb section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
An archery bow having a handle section; limb sections extending from said handle section at both ends thereof; and at least one pair of stabilizers each comprising an elongated vibrating member extending over one of said limb sections, means for elastically supporting said vibrating member, said elastically supporting means being connected with said vibrating member near one end of said vibrating member and also being connected with said one limb section; said vibrating member being directly connected near its other end to said one limb section, at a position spaced from the connection to the bow for said one end, near the other end of said vibrating member.
Claim 2
Dependent Claim
108 words
An archery bow having a handle section; limb sections extending from said handle section at both ends thereof; and at least one pair of stabilizers each comprising an elongated vibrating member extending over one of said limb sections, means for elastically supporting said vibrating member, said elastically supporting means being connected with said vibrating member near one end of said vibrating member and also being connected with said one limb section; said vibrating member being directly connected near its other end to said one limb section, at a position spaced from the connection to the bow for said one end, near the other end of said vibrating member.
Claim 3
Dependent Claim
33 words
The archery bow as claimed in claim 1, wherein said vibrating member is formed into a rod member with a free end, and is provided with a weight at the free end thereof.
Claim 4
Dependent Claim
38 words
The archery bow as claimed in claim 1, wherein said bow has a connecting portion between said handle and said limb sections and said vibrating member is attached to said connecting portion of said handle and limb sections.
Claim 5
Dependent Claim
17 words
The archery bow as claimed in claim 1, wherein said elastically supporting means is a coil spring.
Claim 6
Dependent Claim
58 words
The archery bow as claimed in claim 1, wherein said vibrating member is connected with said one limb section near said vibrating member''s other end by a coupling, said coupling member is frictionally engaged with said vibrating member and said one limb section so that it can be slidable along said vibrating member and said one limb section.
Claim 7
Dependent Claim
25 words
