Abstract

An adjustable stabilizer device for use on a bow to reduce and delay torque and other detrimental forces resulting from shooting thereof, including a housing containing a hydraulic component threadably carried therein. The hydraulic component includes a weight housing carrying a weight centered between opposing springs and moveably contained within hydraulic fluid. The adjustable stabilizer device is adjustable by moving the hydraulic component within the housing to counter differing forces generated by different bows.

Claims

1. An adjustable stabilizer device for use in combination with a bow, said device comprising:

a tubular housing having an attachment end, a free end, and a threaded interior;

attachment means for attaching said tubular housing to said bow; and

a hydraulic component having a threaded exterior configured to threadably engage said threaded interior;

wherein

said hydraulic component is carried within said tubular housing such that the axial position of said hydraulic component is adjustable between said attachment end and said free end.

2. An adjustable stabilizer device as claimed in claim 1 wherein said hydraulic component is fixed into position within said housing by a locking member threadably received within said housing and engaging said hydraulic component.

3. An adjustable stabilizer device as claimed in claim 2 wherein said locking member has a socket formed therethrough for receiving a tool, and said hydraulic component includes an outer end having a socket formed therein for receiving said tool extending through said locking member.

4. An adjustable stabilizer device as claimed in claim 1 wherein said hydraulic component includes:

a weight housing having an inner end and an outer end;

a weight having an inner end and an outer end, slidably carried within said weight housing; and

centering means for centering said weight within said weight housing.

5. An adjustable stabilizer device as claimed in claim 4 wherein said hydraulic component further includes:

an inner end cap having a bore formed therethrough for filling said weight housing with a fluid, said inner end cap coupled to said inner end of said weight housing;

a removable plug receivable within said bore; and

an outer end cap coupled to said outer end of said weight housing.

6. An adjustable stabilizer device as claimed in claim 5 wherein said centering means includes:

first biasing means carried between said inner end cap and said inner end of said weight;

second biasing means carried between said outer end cap and said outer end of said weight; and

spacer means spacing said weight from an inner surface of said weight housing.

7. An adjustable stabilizer device as claimed in claim 6 wherein said spacer means includes rings carried proximate said inner end and said outer end of said weight, said rings having channels formed therethrough permitting passage of fluid.

8. An adjustable stabilizer device as claimed in claim 6 wherein said spacer means includes a plurality of nubs extending radially outward from said weight.

9. An adjustable stabilizer device as claimed in claim 6 wherein said first and said second biasing means include a first and a second spring respectively.

10. A stabilized bow comprising:

a handle riser having a front, a top end, and a bottom end;

a top limb extending from said top end;

a bottom limb extending from said bottom end;

a tubular housing having a free end, an attachment end removably coupled to said front of said handle riser, and a threaded interior; and

a hydraulic component having a threaded exterior configured to threadably engage said threaded interior;

wherein

said hydraulic component is carried within said tubular housing such that the axial position of said hydraulic component is adjustable between said attachment end and said free end.

11. A stabilized bow as claimed in claim 10 wherein said hydraulic component is fixed into position with said housing by a locking member threadably received within said housing and engaging said hydraulic component.

12. A stabilized bow as claimed in claim 11 wherein said locking member has a socket formed therethrough for receiving a tool, and said hydraulic component includes an outer end having a socket formed therein for receiving said tool extending through said locking member.

13. A stabilized bow as claimed in claim 10 wherein said hydraulic component includes:

a weight housing having an inner end and an outer end;

a weight having an inner end and an outer end, slidably carried within said weight housing; and

centering means for centering said weight within said weight housing.

14. A stabilized bow as claimed in claim 13 wherein said hydraulic component further includes:

an inner end cap having a bore formed therethrough for filling said weight housing with a fluid, said inner end cap coupled to said inner end of said weight housing;

a removable plug receivable within said bore; and

an outer end cap coupled to said outer end of said weight housing.

15. A stabilized bow as claimed in claim 14 wherein said centering means includes:

first biasing means carried between said inner end cap and said inner end of said weight;

second biasing means carried between said outer end cap and said outer end of said weight; and

spacer means spacing said weight from an inner surface of said weight housing.

16. A stabilized bow as claimed in claim 15 wherein said spacer means includes rings carried proximate said inner end and said outer end of said weight, said rings having channels formed therethrough permitting passage of fluid.

17. A stabilized bow as claimed in claim 15 wherein said spacer means includes a plurality of nubs extending radially outward from said weight.

18. A stabilized bow as claimed in claim 15 wherein said first and said second biasing means include a first and a second spring respectively.

19. A method of stabilizing a bow comprising the steps of:

providing an adjustable stabilizer device including;

a tubular housing having an attachment end, a free end, and a threaded interior;

attachment means for attaching said tubular housing to said bow; and

a hydraulic component having a threaded exterior configured to threadably engage said threaded interior of said tubular housing;

attaching said adjustable stabilizer device to said bow; and

axially adjusting a position of said hydraulic component within said tubular housing to stabilize said bow.

20. A method as claimed in claim 19 further including the step of:

locking said hydraulic component in position.

21. A method as claimed in claim 20 wherein the step of locking said hydraulic component in position includes:

providing a locking member threaded within said tubular housing; and

engaging said hydraulic component with said locking member, said locking member having a socket formed therethrough for receiving a tool, and said hydraulic component including an outer end having a socket formed therein for receiving said tool extending through said locking member.
