Abstract
Abstract A stabilizer for archery bow comprising an elongated rod member having a weighting element at one end thereof, a number of resilient members each constructed in the form of a plurality of radially extending resilient elements or in the form of a radially extending disklike resilient element, for supporting the other end of the rod member. A housing is provided as a structural member for supporting the radially outward ends of the plurality of radially extending resilient elements or the circumferential portion of the disklike resilient element, whereby when the stabilizer is attached on the archery bow, any shock or vibration created in the archery bow is effectively absorbed and damped out within the stabilizer. In the stabilizer, a screw member for adjusting the tension of the resilient member or members may be further provided between the resilient members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
A stabilizer for an archery bow comprising an elongated member having a weighting element at one end thereof, resilient means engaging the elongated, said resilient means including at least two separate groups of longitudinally spaced-apart radially extending resilient members for supporting said elongated member at the other end thereof, and structural means for supporting and housing said radially extending resilient members and said resilient means dampening the vibrations of a low limb after projection of an arrow.
Claim 2
Dependent Claim
77 words
A stabilizer for an archery bow comprising an elongated member having a weighting element at one end thereof, resilient means engaging the elongated, said resilient means including at least two separate groups of longitudinally spaced-apart radially extending resilient members for supporting said elongated member at the other end thereof, and structural means for supporting and housing said radially extending resilient members and said resilient means dampening the vibrations of a low limb after projection of an arrow.
Claim 3
Dependent Claim
28 words
A stabilizer as defined in claim 1 wherein said other end of the elongated member is supported by central portions of said groups of radially extending resilient members.
Claim 4
Dependent Claim
35 words
A stabilizer as defined in claim 2 wherein said structural means includes a circumferential rim portion, and the outer ends of said plurality of radially extending resilient members are clamped on said circumferential rim portion.
Claim 5
Dependent Claim
23 words
A stabilizer as defined in claim 1 further comprising a housing, said housing fixedly supports the radially extending members of said resilient members.
Claim 6
Dependent Claim
33 words
A stabilizer as defined in claim 1 wherein said resilient members are arranged to form disklike members, and said housing supports the rAdially extending members of said resilient members in a fixed manner.
Claim 7
Dependent Claim
30 words
A stabilizer as defined in claim 5 wherein an adjusting screw for varying the tension of said spaced-apart groups of resilient members is further provided between said two resilient members.
Claim 8
Dependent Claim
48 words
A stabilizer as defined in claim 1 wherein one group of said spaced-apart groups of resilient members is a grommet in said structural means including said grommet, and said elongated member is in supported by said group of said group of spaced-apart resilient members and said one grommet.
Claim 9
Dependent Claim
36 words
A stabilizer as defined in claim 7 wherein said structural comprises a housing, said housing fixedly supports the radially extending resilient members of another group of said groups of spaced-apart resilient members and of said grommet.
Claim 10
Dependent Claim
43 words
A stabilizer as defined in claim 8 wherein an adjusting screw for adjusting the tension of said another group of said group of spaced-apart resilient member is further provided between said another group of said group of spaced-apart resilient members and said grommet.
Claim 11
Dependent Claim
34 words
A stabilizer as defined in claim 9 wherein a stub shaft being provided for mounting said members and said grommet, and one end of said stub shaft being fixedly connected to said elongated member.
Claim 12
Dependent Claim
59 words
A stabilizer as defined in claim 1 wherein each group of said groups of spaced-apart resilient members is formed in the shape of a disklike member, said structural means comprising a housing of a comparatively long length, and said elongated member is made into a rod member which passes through a grommet and is connected to said disklike member.
