| 20120000451 | ADJUSTABLE DRAW STOP FOR ARCHERY BOWS - A draw length adjustment system including a draw stop, an adjustment element and a fastener that joins the draw stop and/or adjustment element with a cam or pulley of an archery bow. The draw length adjustment system is micro-adjustable so that an archer can make minute and/or incremental adjustments to the draw stop, and thus the draw length of the archery bow. The draw stop can be of an eccentric construction that is eccentrically rotatable relative to the cam or pulley to alter the draw length. Alternatively, the draw stop can be selectively moveable relative to the cam assembly via a rack and pinion gear to alter the draw length. | 01-05-2012 |
| 20110023857 | CAM ADJUSTMENT MODULE FOR COMPOUND ARCHERY BOW - A cam system for an archery bow including a module that is readily attached to and detached from a cam while leaving the cam on the bow. The module can include a draw stop selectively moveable relative to the module, even while the module is joined with the cam, to adjust the draw stop to specific locations corresponding to different draw lengths and/or draw stop walls of the bow. The module can include a recess that surrounds only part of an axle joining the cam and bow so the entire module is removable from the cam without removing the axle. The cam system can include indexing features that precisely and consistently align features of the cam and module. These features can include first and second indexing posts, and corresponding indexing holes, that register with one another to precisely align the cam and module when joined. | 02-03-2011 |
| 20110011385 | CABLE GUARD AND GUIDES FOR ARCHERY BOWS - An archery bow is provided including a cable guard and/or cable guide that can flex to selectively move a cable relative to a plane in which a bowstring of the bow travels to minimize cam lean, limb twist, and/or cable wear. The cable guard and/or guide can move toward the bowstring plane as the bowstring is drawn, and away from the bowstring plane, out of the way of the bowstring and any attached arrow, after the bowstring is released. The cable guard can define a bore, for example, an elongated bore, extending through it along an axis that is generally parallel to the bowstring when the bowstring is undrawn. The cable guard bore can operate as a cable guide, and can include a rounded opening to minimize abrasion to a cable moving through it. A ceramic element can be included in the bore to minimize abrasion to the cable. | 01-20-2011 |
| 20100319669 | BOWSTRING SUPPRESSOR - A bowstring suppressor for an archery bow including a suppressor assembly and/or a bowstring attachment element. The assembly can include a housing within which resilient elastomeric elements are located. A push rod can be telescopically joined with the housing and located near the resilient elements. An engagement element can be joined with the push rod and can be engaged by a bowstring when an arrow is shot from the bow. The push rod can move toward the resilient elements and compress them when the bowstring engages the engagement element. Compression of the resilient elements provides energy absorption, vibration absorption and/or dampening in relation to energy generated by the bow. A string attachment element can be joined with the bowstring and can engage the suppressor assembly, with the attachment element seating in and optionally deforming the engagement element, which in turn, restrains lateral and vertical movement of the bowstring. | 12-23-2010 |
| 20100154769 | ARCHERY STRING NOCK - A speed nock for use with an archery bow includes a first enlarged portion and a second enlarged portion connected via a central portion. The central portion has a maximum dimension smaller than maximum dimensions of the first and second enlarged portions. The central portion is positioned between strands of a bowstring of the bow so that the strands pinch the central portion, at least assisting in holding the speed nock in place along the bowstring. The speed nock can be moved along the bowstring to a selected location that maximizes energy imparted to an arrow shot from the archery bow, and thus the speed of the arrow. A related method of using the speed nock above is also provided. | 06-24-2010 |
| 20100101549 | CABLE GUARD AND GUIDE FOR ARCHERY BOWS - An archery bow includes a cable guard and an optional cable guide that holds a cable of the bow away from a plane in which a bowstring of the bow moves. The cable guard can define a bore, through which the cable is positioned, extending generally parallel to the bowstring when the bowstring is in an undrawn state. The cable guard bore can include a rounded opening to minimize abrasion to the cable. The cable guide can include a ceramic element having a rounded surface to minimize abrasion to the cable. The ceramic element can be included in an immovable or stationary cable guide, as well as an alternative cable guide including moving components, to engage and hold the cable away from the bowstring, while minimizing abrasion and/or friction on the cable. | 04-29-2010 |

| 20090098960 | BATTERY HOLDER FOR A LIGHTED ARCHERY NOCK - The present invention generally relates to a lighted archery nock. The lighted archery nock generally includes an accelerometer, a replaceable battery, a light, a housing, and a microprocessor that controls illumination of the light. The microprocessor can control the timing of the light to save battery life and respond to user input transmitted by tapping the nock to re-set the light. The housing is configured with a plurality of fingers that interact with the replaceable battery to hold it in place. | 04-16-2009 |
| 20090098959 | PROGRAMMABLE LIGHTED ARCHERY NOCK - The present invention generally relates to a lighted archery nock. The lighted archery nock generally includes an accelerometer, a replaceable battery, a light, a housing, and a microprocessor that controls illumination of the light. The microprocessor can control the timing of the light to save battery life and respond to user input transmitted by tapping the nock to re-set the light. The housing is configured with a plurality of fingers that interact with the replaceable battery to hold it in place. | 04-16-2009 |
| 20090097239 | LIGHTED ARCHERY NOCK WITH VARIABLE LIGHT EMISSIONS - The present invention generally relates to a lighted archery nock. The lighted archery nock generally includes an accelerometer, a replaceable battery, a light, a housing, and a controller that controls illumination of the light. The controller can control emission of the light to conserve battery life, and can respond to user input transmitted by tapping the nock to re-set the light. The housing is configured with a plurality of fingers that secure the replaceable battery. | 04-16-2009 |
