Archery stabilizer

Abstract

An archery stabilizer includes a tubular member and an insert member. The tubular member has a first end, a second end and an interior sidewall defining an interior bore that extends between the first end and the second end. The tubular member has a first resonance frequency. The insert member is positioned in the interior bore and extends for more than one third of the length of the tubular member. The insert member has an exterior surface. The insert member has a second resonance frequency that differs from the first resonance frequency. A vibration dampening gel is positioned between the exterior surface of the insert member and the interior sidewall of the tubular member. A mounting assembly is positioned at the first end of the tubular member, whereby the archery stabilizer is mounted to an archery bow. A weight support assembly is positioned at the second end of the tubular member, whereby one or more weights are supported.

DETAILED DESCRIPTION

(5) An archery stabilizer generally identified by reference numeral 10, will now be described with reference to FIG. 1 through FIG. 3.

(6) Structure and Relationship of Parts:

(7) Referring to FIG. 1, archery stabilizer 10 is illustrated. Referring to FIG. 2, the components of archery stabilizer 10 are shown in an exploded view. A tubular member 12 is provided having a first end 14, a second end 16, and an exterior surface 18. Referring to FIG. 1, features of tubular member 12 not visible in FIG. 1 are an interior sidewall 20 which serves to define an interior bore 22. Interior bore 22 extends between first end 14 and second end 16.

(8) Tubular member 12 has a first resonance frequency.

(9) Referring to FIG. 1, an insert member 24 is positioned in interior bore 22, extending from first end 14 for more than one third of the length of tubular member 12. It will be noted that insert member 24 is also tubular. Referring to FIG. 2, insert member 24 has a first end 26, a second end 28, and an exterior surface 30. Second end 28 is closed by a closure in the form of a bullet shaped cap 32. Insert member 24 has a second resonance frequency that differs from the first resonance frequency of tubular member 12.

(10) Referring to FIG. 1, vibration dampening gel 34 is positioned between exterior surface 30 of insert member 24 and interior sidewall 20 of tubular member 12. It is preferred that vibration dampening gel 34 encapsulate insert member 24 (including bullet-shaped cap 32) and also be bonded to interior sidewall 20 of tubular member 12.

(11) Referring to FIG. 1, a mounting assembly, generally indicated by reference numeral 36, is provided at first end 14 of tubular member 12, whereby archery stabilizer 10 is mounted to an archery bow 100, as shown in FIG. 3. Referring to FIG. 2, mounting assembly 36 includes a body 38 having a collar 40. Referring to FIG. 1, collar 40 overlies exterior surface 18 at first end 14 of tubular member 12. Referring to FIG. 2, a cantilevered bow mounting screw 42 is provided having a first end 44 supported by body 38 and a remote end 46. A lock washer 48 is provided to maintain first end 44 of mounting screw 42 engaged with body 38. An annular mounting plug 50 is provided. Referring to FIG. 1, annular mounting plug 50 has an exterior surface 52 that engages interior sidewall 20 of tubular member 12 and an interior surface 54 that engages exterior surface 30 of insert member 24. Referring to FIG. 2, annular mounting plug 50 is coupled with body 38 by mating threaded connection 56. It is preferred that first end 44 of mounting screw 42 engage a bore 58 in annular mounting plug 50, as through a series of threaded connections insert member 24, tubular member 12 and mounting screw 42, which engages archery bow 100 as shown in FIG. 3, become mechanically fastened together.

(12) Referring to FIG. 1, a weight support assembly, generally identified by reference numeral 60, is provided at second end 16 of tubular member 12, whereby one or more weights 62 are supported. Referring to FIG. 2, weight support assembly 60 includes a body 64 having a collar 66. Referring to FIG. 1, collar 66 overlies second end 16 of tubular member 12. Referring to FIG. 2, a cantilevered weight attachment screw 68 is provided having a first end 70 supported by body 64 and a remote end 72. One or more weights 62, are provided with each weight 62 having a mounting aperture 74 that slides over remote end 72 of weight attachment screw 68. A screw end cap 76 is provided which engages remote end 74 of weight attachment screw 68 to prevent weights 62 from sliding off remote end 74.

(13) Operation:

(14) Referring to FIG. 1, resonance vibration travels along two paths created by tubular member 12 and insert member 24. These two vibration paths are isolated by vibration dampening gel 34. Tubular member 12 vibrates at a first resonance frequency. Insert member 24 vibrates at a second resonance frequency, that differs from the first resonance frequency, due to the difference in diameter and wall thickness between tubular member 12 and insert member 24. Vibration dampening gel 34 absorbs vibration in both directions. Referring to FIG. 3, vibration is absorbed whether the vibration is traveling from archery bow 100 through mounting assembly 36 toward weight support assembly 60 or whether the vibration is traveling back from weight support assembly 60 toward mounting assembly 36 and archery bow 100.

(15) Referring to FIG. 1, tubular insert member 24 and outer tubular member 12 vibrating at different frequencies are suspended in vibration dampening gel 34 allow vibration dampening gel to absorb the energy and dampen the vibration before the shockwave returns to the archer. Dampening is the loss of dissipation of energy over time. This dampening zone of stabilizer 10 allows for a longer dampening area than using a localized rubber insert or donut around or in the stabilizer, as is common in the industry. The length of the zone allows it to absorb a variety of vibration frequencies regardless of whether the wavelengths are long or short. Because this dampening zone has the added benefit of being around a hollow inner tube of tubular insert member 24, it does not add unnecessary weight to first end 14 of stabilizer 10, which would work against moving the mass as far forward as possible.

(16) In this patent document, the word comprising is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article a does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.

(17) The scope of the claims should not be limited by the illustrated embodiments set forth as examples, but should be given the broadest interpretation consistent with a purposive construction of the claims in view of the description as a whole.
