  • Patent number: 8449415
    Abstract: A mechanical broadhead including rearwardly deploying and/or sliding blades. The broadhead includes a ferrule defining a bore joined with a penetrating tip. A connector body, such as a carriage element or a pin, is slidably and moveably disposed within the bore, distal from the tip. One or more cutting blades is joined with the connector body. The connector body moves together in unison with the cutting blades as they expand from a retracted, in flight mode to a deployed, target penetrating mode. The connector body and blades can be joined with the ferrule so that the broadhead converts from a deployed mode to an unbarbed mode to facilitate broadhead removal. Optionally, the broadhead can include an internal retainer element that is resilient and durable enough to be used for multiple deployments. A related method of operating the broadhead also is provided.

  • Patent number: 8424511
    Abstract: 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.

  • Publication number: 20130081604
    Abstract: An accessory mounting system for mounting a first object to a second object is provided. The system can be used to mount a quiver to an archery bow, or an archery or hunting accessory. The system can include a primary element having a projection that fits into an aperture defined by a secondary element. The secondary element can include a base, an engagement member and an actuator. The base can define at least a portion of an aperture. To the base, the engagement member can be moveably mounted to clampingly engage the projection when in the aperture. The actuator can be configured to actuate the engagement member, thereby fixedly mounting the secondary element to the projection. A related method of use also is provided.

  • Patent number: 8372478
    Abstract: A method is provided for surface treating a substrate utilizing powder coating so that the substrate can be adorned with a decorative pattern and/or color, and can have a durable, aesthetically appealing finish. The decorative pattern can be applied via transfer printing processes, for example, by a sublimation process or a hydrographic process. The method optionally can be used to produce a visually perceivable transition between a decorative pattern, for example, a camouflage pattern, and a generally solid color on the substrate. The transition can be gradual, so that the decorative pattern appears to fade into the generally solid color to provide an appealing visual effect on a product. The method can be used to surface treat a variety of products, for example, archery products and/or firearm products.

  • Patent number: 8371283
    Abstract: 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.

  • Patent number: 8365713
    Abstract: 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.

  • Publication number: 20130000621
    Abstract: 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.

  • Publication number: 20120272939
    Abstract: An archery bow is provided including a cable guard and/or cable guide including a cable facing surface which can include an e-coat film to minimize wear and abrasion on a cable, bowstring or other element that engages the surface. The cable guard and/or cable guide 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.

  • Publication number: 20120178560
    Abstract: A mechanical broadhead having blades movable from a retracted mode to a deployed mode is provided including a generally external retainer element which holds the blades in the retracted mode, but also selectively releases the blades so that they can transition to the deployed mode. The retainer element can include a collar and one or more tabs. A blade can include a projection and/or a recess that is engaged by one or more tabs to secure the blade in the retracted position. The tabs can be paired and can define a retainer slot therebetween. The blade can be at least partially disposed in the retainer slot in the retracted mode and/or in the deployed mode.

  • Patent number: 8109261
    Abstract: 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.

  • Publication number: 20120000451
    Abstract: 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.
