Archery Bow Eccentric Alignment and Related Apparatuses

This application claims the benefit and is a continuation of U.S. patent application Ser. No. 18/242,409, filed Sep. 5, 2023, the entire contents of which are hereby incorporated herein by reference.

The present disclosure generally relates to archery equipment and specifically relates to members aligning eccentrics on an archery bow.

Archery equipment, such as recurve bows, crossbows, and compound bows, are regularly used to launch arrows and other projectiles down range at one or more targets. Components of the archery bow work in unison to provide accurate and repeatable arrow flight while also providing a desirable user experience (e.g., satisfactory vibration and sound characteristics). Archery accessories, such as a sight, can be affixed to the archery bow to increase utility and directly impact user satisfaction. Components and accessories for archery bows can be improved to advantageously impact an archer's shooting experience, performance, and overall satisfaction with the archery equipment.

One aspect of the present disclosure relates to an archery bow comprising a riser, a limb, a cam, and a member. The limb can extend from the riser. The cam is rotatably coupled to the limb by an axle. The member contacts the axle and has a shim portion positioning the cam a distance from the limb. The member defines a first surface facing the limb and a second surface facing the limb. The first surface is different from the second surface.

In some examples, the first surface can face a lateral surface of the limb and the second surface can face a tensile surface or a compressive surface of the limb. In some examples, the first surface can extend perpendicularly relative to the second surface. In some examples, the axle can include a groove and a portion of the member can be disposed within the groove. In some examples, the archery bow can further include a fastener coupling the second surface to a tensile surface or a compressive surface of the limb. In some examples, the member can define a first end contacting the axle at a first location. The member can define a second end contacting the axle at a second location. The first location can be spaced a distance from the second location along a length of the axle. The distance can be at least equivalent to a width of the limb.

In some examples, the member can include a mount portion coupled to the limb. The shim portion can be repositionable relative to the mount portion. In some examples, the limb can be a first limb and the member can be a first member having a first shim portion. The archery bow can further include a second limb extending from the riser and a second member contacting the axle. The second member can have a second shim portion displacing the cam a distance from the second limb. The second member can define a third surface facing the second limb and a fourth surface facing the second limb. The third surface is different from the fourth surface. The first shim portion can have a first thickness and the second shim portion can have a second thickness less than the first thickness.

Another aspect of the disclosure relates to an archery bow including a riser, a limb, an axle, a cam, and a member. The limb extends from the riser. The axle is coupled to the limb. The axle has a first end and a second end. The cam is rotatable about the axle. The member includes a shim portion and an engagement portion. The shim portion locates the cam a distance from the first end of the axle. The engagement portion couples the member to at least one of the first end of the axle or the limb.

In some examples, the member can include an intermediate portion disposed between the shim portion and the engagement portion. The intermediate portion can face a tensile surface or a compressive surface of the limb. In some examples, the engagement portion can define an aperture. The engagement portion can be coupled to the axle by a fastener extending through the aperture. The member can be partially disposed within a groove in the axle. In some examples, the shim portion can include a spacing feature having an arcuate segment and a linear segment.

Yet another aspect of the present disclosure relates to an archery bow including a riser, a limb, an axle, a cam, and a member. The limb extends from the riser. The axle is coupled to the limb. The axle has a groove disposed between a first end and a second end of the axle. The cam is rotatable about the axle. The member contacts the axle and is disposed between the cam and the limb. The member includes a main body, a shim portion, and a nesting feature. The nesting feature is receivable within the groove.

In some examples, the main body has a first thickness and the shim portion has a second thickness. A maximum thickness of the member can be defined by a summation of the first thickness and the second thickness. In some examples, the groove can extend around a circumference of the axle. In some examples, the nesting feature can be disposed within an aperture defined by the main body.

The above summary of the present invention is not intended to describe each embodiment or every implementation of the present invention. The Figures and the detailed description that follow more particularly exemplify one or more preferred embodiments.

While the embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the exemplary embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.

An archery bow can include one or more limbs coupled to one end of a riser and one or more limbs coupled to another end of the riser. For example, an archery bow can have a pair or set of limbs coupled to one end of the riser. The pair of limbs can define a gap or space accommodating a cam rotatably coupled between the limbs via an axle. Modifying the spacing between each limb and the cam within the gap can affect arrow tuning characteristics of the archery bow by manipulating cam lean and/or shifting a shooting plane of the archery bow. Replacing spacers between the cam and the respective limbs can require completely or partially removing the cam and/or axle from the limbs. Removing the axles can be a cumbersome and tedious process, sometimes requiring specialized tools, that does not allow an archer to easily and quickly adjust cam spacing without investing substantial time, energy, and expertise in disassembling and reassembling at least a portion of the archery bow.

One aspect of the present disclosure generally relates to a member for an archery bow which enables an archer to reposition a shooting plane of the bow by varying a spacing of eccentrics or cams relative to limbs of the archery bow in a relatively straightforward manner. In some examples, a set of members can be swapped or replaced without removing the axle or cam from the limbs. The archery bow can include a riser, a limb, a cam, and a member. The limb can extend from the riser and the cam can be rotatably coupled to the limb by an axle. The member can engage the axle such that a shim portion of the member displaces or positions the cam a distance from the limb. For example, the shim portion can act as a spacer disposed between the limb and the cam. The distance the shim portion displaces the cam from the limb can correlate to a position of the shooting plane. Thus, varying the distance can enable an archer to modify the shooting plane of the archery bow. In some examples, the members can be replaceable such that a member having a shim portion of a particular thickness can be replaced with a different member having a shim portion with a different thickness to vary the distance or spacing of the eccentric or cam relative to the limbs. Additionally, or alternatively, in some examples, the members can be swappable such that respective positions of a set of members can be swapped to vary the spacing of eccentrics or cams relative to limbs and thereby shift the shooting plane of the archery bow.

In some examples, each member can include various portions (e.g., shim portions, engagement portions, intermediate portions, etc.) which extend along two or more surfaces of the limb when the member is coupled to the archery bow. The portions can be respective sections of the member that define a first limb-facing surface (i.e., a first surface) and a second limb-facing surface (i.e., a second surface). In some examples, the first surface or first limb-facing surface can abut or extend adjacent to a lateral or side surface of the limb. In some examples, the second surface or second limb-facing surface can abut or extend adjacent to a tensile or compressive surface of the limb.

In some examples, the member can contact the axle at multiple distinct contact points. For example, the member can have first and second ends contacting respective contact points on the axle. The first contact point can be located between respective ends of the axle. The second contact point can be at or near one of the ends of the axle. In other words, in some examples, each member can include two or more contact points that are spaced from one another along the length of the axle. In some examples, the first end of the member can engage the first contact point such that the member can be pulled away from the axle without removing the axle from the limb(s). For example, the first end can form a clip or other attachment that can be engaged at the first contact point by sliding or snapping the first end onto the axle at the first contact point. Similarly, the first end can be disengaged or removed from the axle by sliding or unclipping the first end from the first contact point of the axle.

Some archery bows couple the cam assembly (e.g., axle, spacers, cam, bearings, module, etc.) to the limbs by applying a compressive force to the limbs via one or more fasteners that are receivable within a threaded aperture on either end of the axle. This compressive force can generate an undesirable thrust load applied to the bearings of the cam. In another aspect of the present disclosure, the member can include a nesting feature that is received within and engages a groove or channel within the axle to mitigate or eliminate thrust loading exerted on one or more bearings coupled to the cam. For example, compressive forces applied to the limbs can generate a thrust load that is transferred through the member and into the axle via the engagement between the nesting feature of the member and the groove in the axle. In some examples, the nesting portion can be relatively thinner than the shim portion.

The present description provides examples, and is not limiting of the scope, applicability, or configuration set forth in the claims. Thus, it will be understood that changes may be made in the function and arrangement of the members and/or other elements of the archery bow discussed without departing from the spirit and scope of the disclosure, and various embodiments may omit, substitute, or add other procedures or components as appropriate. For instance, features described with respect to certain embodiments may be combined in other embodiments. The specific examples shown in the figures and described herein should not, therefore, be considered to limit the breadth of possible embodiments and combinations of possible embodiments contemplated by the present disclosure.

Referring now to the figures in detail,shows a compound archery bow. The archery bowis at a rest position (e.g., a brace state or brace position). The archery bowcan comprise a riserfrom which one or more upper limbs(e.g., first limbA and second limbB) and one or more lower limbsextend. For example, the upper limbscan be affixed to the riserby one or more limb pockets. The archery bowcan include a handle portion or grip, a roller guard or cable guard, a string-stop damper, riser dampers, limb dampers, and other components.

The upper limbsmay be connected to an upper cam assembly, and the lower limbsmay be connected to a lower cam assembly. A bowstring(i.e., draw string) may extend across the length of the archery bowbetween the upper cam assemblyand the lower cam assembly. The terminal ends of the bowstringmay be attached to and held entrained to the cam assemblies,, at least in the brace position, and the limbs,may be flexed to store energy and retain tension in the bowstring. A first cableand a second cablemay also be attached to and extend between the upper cam assemblyand the lower cam assembly. Collectively, the first cableand the second cablemay be referred to herein as the cables of the archery bow. The first and second cables,may retain tension in the limbs,and cam assemblies,and may be controlled to adjust tension in the bowstring.

The figures illustrate example archery apparatuses that may be used in conjunction with the principles and teachings of the present disclosure. Thus, while the archery bows described herein are compound bows, it will be understood by those having ordinary skill in the art that the components of the archery bow, accessories, and related methods and apparatuses included in embodiments of the present disclosure may be applied to components and apparatuses in compound bows, crossbows, their accessories, and other equipment related to archery. Similarly, archery equipment applying the teachings of the present disclosure does not need to implement all of the features of the present disclosure. For example, in some embodiments, the archery bow may not comprise a cable guardor a string-stop damper, so features associated with those accessories may be omitted from the archery bow.

When shooting an arrow, the tail end of the arrow may be nocked with the bowstringat a nocking point (not shown) while the archery bowis in the brace position shown in. The bowstringmay be drawn rearward to a full draw position, thereby partially unraveling the bowstringfrom the outer grooves of the cam assemblies,. The archer may grasp the gripof the riserand draw back the bowstring(e.g., by using a D-loop, not shown). As the limbs,flex inward and the cables,wind around the cam assemblies,, the cables,may slide along or may be in rolling contact with portions of the cable guard, which may comprise at least one roller or other smooth support in contact with the cables,where they contact the cable guard.

When the bowstringis released, the potential/stored energy in the limbs,is released, and the bowstringquickly accelerates back toward the brace position (shown in) as it applies a shooting force to an end of the projectile (e.g., an arrow). As the limbs,release their energy, the cam assemblies,are spread apart, and the terminal ends of the bowstringwrap around the cam assemblies,, and the cables,unwind from the cam assemblies,. A portion of the bowstringmay contact the string-stop damper, which can help dampen vibrations in the bowstring, and the cables,may roll or slide against the cable guardas the cam assemblies,move. After returning to the brace condition, the arrow is launched from the archery bowalong a shooting axis A. The shooting axis Aand the bowstringcan define a shooting plane P(see). A position of the shooting plane Pbetween the upper limbsand/or the lower limbscan influence the efficiency of arrow flight (e.g., affect how the arrow is departs the bowstringand launches from the archery bow).

andshow the upper cam assemblyrotatably coupled to the first and second limbsA,B (e.g., upper limbs). In some examples, the upper cam assemblyis rotatably coupled to the first and second limbsA,B by an axle(see e.g., axlein). In some examples, a set or pair of members can displace or space the upper cam assemblybetween the first and second limbsA,B. For example, the upper cam assemblycan be displaced or spaced from the first limbA by a first memberA. The upper cam assemblycan be displaced or spaced from the second limbB by a second memberB. In other words, at least a portion of the first and second membersA,B can act as spacers disposed between the upper cam assemblyand the respective first and second limbsA,B to locate the upper cam assemblyrelative to the first and second limbsA,B.

In some examples, each of the first and second membersA,B can be coupled to the axle. Additionally, or alternatively, one or both of the first and second membersA,B can be coupled to the first or second limbsA,B. For example, the first memberA can be affixed, fastened, or otherwise coupled to the first limbA. Similarly, the second memberB can be affixed, fastened, or otherwise coupled to the second limbB. In some examples, the first memberA can be removed from the first limbA and/or the axleand affixed to the second limbB while the second memberB can be removed from the second limbB and/or axleand affixed to the first limbA (seeand).

A position or location at which the upper cam assemblyis held on the axlerelative to the first and second limbsA,B by the first and second membersA,B can correlate to a position or location of the shooting plane P. The opportunity for an archer or bow technician to manipulate the lateral position of the shooting plane Prelative to the upper limbscan affect arrow tuning characteristics of the archery bow. While not depicted in, in some examples, the lower cam assemblycan be repositionable relative to the lower limbsby one or more respective members substantially similar to, including some or all of, the features of the first and second membersA,B. Thus, in some examples, both the upper and lower cam assemblies,can be laterally manipulated relative to their respective limbs to adjust the shooting plane Pof the archery bow.

shows the first and second members in a first configuration wherein the shooting plane Pis displaced a first distance dfrom the first limbA and the displaced a second distance dfrom the second limbB. In some examples, the first distance dcan be relatively lesser or smaller than the second distance dsuch that the shooting plane Pis located or disposed relatively closer to the first limbA than the second limbB. In some examples, the first distance dcan be relatively greater or larger than the second distance dsuch that the shooting plane Pis located or disposed relatively closer to the second limbB than the first limbA. In some examples, the first distance dcan be equal to or substantially equal to the second distance dsuch that the shooting plane Pis located or disposed at a midpoint between a gap Gbetween the first limbA and the second limbB.

In the first configuration (shown in), the first memberA can be affixed to the first limbA and/or coupled to the axleadjacent to the first limbA. In the first configuration, the second memberB can be affixed to the second limbB and/or coupled to the axleadjacent to the second limbB. In the first configuration, the upper cam assemblycan be displaced from the first limbA by a first shim thickness Tand displaced from the second limbB by a second shim thicknesses T. The first and second shim thicknesses T, Tcan be defined by a portion of each memberA,B disposed between the upper cam assemblyand each respective upper limbA,B. For example, the first shim thickness Tcan be defined by a first shim portionA of the first memberA and the second shim thickness Tcan be defined by a second shim portionB of the second memberB. In some examples, the first shim thickness Tcan be relatively lesser or smaller than the second shim thickness Tsuch that the upper cam assemblyis located or disposed relatively closer to the first limbA than the second limbB. In the first configuration, the first distance dcan be less than the second distance dsuch that the shooting plane Pis relatively closer to the first limbA than the second limbB. In some examples, the first shim thickness Tcan be less than about 0.015 inches, between about 0.015 inches and about 0.05 inches, between about 0.05 inches and about 0.1 inches, between about 0.1 inches and about 0.15 inches, between about 0.15 inches and about 0.25 inches, between about 0.25 inches and about 0.35 inches, or greater than 0.35 inches. In some examples, the second shim thickness Tcan be less than about 0.015 inches, between about 0.015 inches and about 0.05 inches, between about 0.05 inches and about 0.1 inches, between about 0.1 inches and about 0.15 inches, between about 0.15 inches and about 0.25 inches, between about 0.25 inches and about 0.35 inches, or greater than 0.35 inches.

In a second configuration, shown in, the first memberA can be affixed to the second limbB and/or coupled to the axleadjacent to the second limbB. In the second configuration, the second memberB can be affixed to the first limbA and/or coupled to the axleadjacent to the first limbA. In other words, in the second configuration, the position of the first and second membersA,B on the first and second limbsA,B, respectively, are swapped compared to the first configuration. As such, the upper cam assemblycan be displaced from the first limbA by the second shim thickness Tand displaced from the second limbB by the first shim thicknesses T. In some examples, the first shim thickness Tcan be relatively lesser or smaller than the second shim thickness Tsuch that the upper cam assemblyis located or disposed relatively closer to the second limbB than the first limbA. In the second configuration, the first distance dcan be greater than the second distance dsuch that the shooting plane Pis relatively further from the first limbA than the second limbB. The membersA,B will be further described below with reference to.

shows a memberthat is substantially similar to, and can include some or all of the features of the membersA,B. For example, the membercan be affixed to an axle and/or a limb of an archery bow to displace or locate a cam of the archery bow relative to the limb. In some examples, the membercan include one or more portions, such as, a shim portion, an intermediate portion, and/or an engagement portion. In some examples, one or more of these portions can be integrally formed from a continuous material, such as, a singular or unitary molded or machined component. In some examples, one or more of these portions can be discretely formed and thereafter welded, adhered, fastened, or otherwise coupled together to form the member.

The shim portioncan extend from the intermediate portionto at least partially position the shim portionbetween a limb (e.g., limbA) and a cam assembly (e.g., cam assembly) of the archery bow. For example, the shim portioncan extend substantially perpendicular from the intermediate portionsuch that the shim portionand the intermediate portiongenerally form a right angle. In other examples, the shim portioncan extend from the intermediate portionto form an angle less than 90 degrees or greater than 90 degrees.

In some examples, the shim portionincludes a spacing featureand a nesting feature. The spacing featurecan be arranged and positioned on the shim portionsuch that the spacing featureis the only section of the shim portionthat contacts an inner race of a cam bearing leaving the remainder of the cam bearing to freely rotate about the axle. In some examples, as shown in, the spacing featurecan define or form a section of the shim portionthat is relatively thicker or wider than a section of the shim portiondisposed adjacent the intermediate portion. In other words, the spacing featurecan extend or protrude from a lateral surfaceof the shim portionto space or displace the cam from the lateral surface. The spacing featurecan be disposed about a portion of the shim portionlocated adjacent to the axle (see) while the memberis affixed to the axle. In some examples, the spacing featurecan be formed from one or more arcuate segments and linear segments. For example, the spacing featurecan include a single arcuate segmentthat transitions into two linear segmentsA,B that extend parallel to one another.

The nesting featurecan be defined as a protrusion or extension disposed within a concavity or recessed structure defined by the shim portion. For example, the concavity or recessed structure can be u-shaped or otherwise open-ended such that the shim portioncan be at least partially disposed about the axle (see) and the nesting featurecan be at least partially insertable into a groove or channel (seeA,B at) formed within the axle (seeand). While the nesting featureis disposed within the groove or channel of the axle, a potential thrust load on the bearing can be mitigated or eliminated by transferring compressive loading from the member to the axle rather than a cam bearing. As such, while inserted on the axle, the membercan be prevented from sliding or translating along the axle due to an engagement formed between the nesting featureand the groove or channel formed within the axle.

In some examples, the spacing featurecan have a first thickness Tand the nesting featurecan have a second thickness T(see). A maximum thickness Tof the shim portioncan be equal to a summation of the first and second thicknesses T, T. In other words, the first and second thicknesses T, Tcan define the maximum thickness Tof the shim portion. In some examples, the first thickness Tcan be greater or larger than the second thickness T. In some examples, the first thickness Tcan be lesser or smaller than the second thickness T. In some examples, the first thickness can be less than about 0.015 inches, between about 0.015 inches and about 0.05 inches, between about 0.05 inches and about 0.1 inches, between about 0.1 inches and about 0.15 inches, between about 0.15 inches and about 0.25 inches, between about 0.25 inches and about 0.35 inches, or greater than 0.35 inches. In some examples, the second thickness can be less than about 0.015 inches, between about 0.015 inches and about 0.05 inches, between about 0.05 inches and about 0.1 inches, between about 0.1 inches and about 0.15 inches, between about 0.15 inches and about 0.25 inches, between about 0.25 inches and about 0.35 inches, or greater than 0.35 inches.

In some examples, the intermediate portioncan extend between or span the shim portionand the engagement portion. This extension or span can accommodate at least a portion of an archery limb disposed between the shim portionand the engagement portion. For example, the extension or span defined by the intermediate portioncan be substantially equal to or greater than a width of a limb of an archery bow. In some examples, the intermediate portioncan include an aperture. The aperturecan extend wholly through the intermediate portionin some examples. In other examples, the aperturemay only partially extend through the intermediate portion. The aperturecan enable an archer or archery technician to insert an object, such as a tool, into the memberto pry or bias the memberfrom engagement with an axle, for example, to remove one or more membersfrom an archery bow.

In some examples, the membercan include an accessory featureenabling one or more accessories or other components to couple to the member. For example, a limb-driven arrow rest (not shown) can be coupled to the accessory featurevia a cable or cord to facilitate a drop-away functionality of the arrow rest. In some examples, the cable or cord can be tied or otherwise affixed within one or more aperturesdefined or formed within the accessory feature. The aperturecan be one or more through-holes or blind holes. In some examples, the aperturecan have a relatively smooth bore. In some examples, the aperturecan have a bore that is threaded, partially threaded, slotted, chamfered, countersunk, counterbored, or a combination thereof. While the accessory featureis shown as extending from the intermediate portion, the accessory featurecan additionally, or alternatively, be formed or defined as part of the shim portionand/or the engagement portionin some examples.

In some examples, the membercan include one or more reliefs, such as, the one or more reliefswithin the intermediate portionshown in. Each of the one or more reliefscan provide clearance or otherwise enable access to other components of the archery bow. For example, each of the one or more reliefscan enable access and removal or insertion of one or more fasteners disposable within the distal ends of each limb of the archery bow. While the one or more reliefsare shown as formed within the intermediate portion, the one or more reliefscan additionally, or alternatively, be formed or defined within the shim portionand/or the engagement portionin some examples.

The engagement portioncan extend from the intermediate portionto be at least partially position adjacent to the lateral outside surface of the limb (i.e., opposite the lateral surface of the limb facing the cam) of the archery bow. For example, the engagement portioncan extend substantially perpendicular from the intermediate portionsuch that the engagement portionand the intermediate portiongenerally form a right angle. In other examples, the engagement portioncan extend from the intermediate portionto form an angle less than 90 degrees or greater than 90 degrees.

In some examples, the engagement portioncan include an apertureenabling a user to couple the memberto an axle of an archery bow, for example, with a fastener (see) or e-clip. The aperturecan be chamfered, countersunk, counterbored, threaded, keyed, or a combination thereof in some examples. For example, as shown in, the aperturecan be a countersunk slotted through-hole extending through the engagement portion. In some examples, a diameter of the aperturecan be smaller than a diameter of the axle (seeand) such that the axle abuts or is otherwise disposed adjacent to an internal or limb-facing surfaceof the engagement portion. In other examples, a diameter of the aperturecan be larger than a diameter of the axle such that the axle partially extends through the aperture.

In some examples, each of the shim portion, the intermediate portion, and the engagement portioncan form or define respective limb-facing surfaces such that the memberincludes multiple limb-facing surfaces. For example, the shim portioncan include a first surface or first limb-facing surfaceand the intermediate portioncan include a second surface or second limb-facing surface. In some examples, the first limb-facing surfacecan be adjacent to and/or face a lateral surface of the limb (e.g., a side surface of the limb that is disposed closest to the cam). In some examples, the second limb-facing surfacecan be adjacent to and/or face a tensile surface or compressive surface of the limb (e.g., a surface of the limb disposed between the lateral or side surfaces). In some examples, the archery bow can include a second member (see memberB in) and the second member can form or define third and fourth surfaces that each face a second limb of the archery bow. The third and fourth surfaces can be different from one another.

In some examples wherein the member includes the engagement portion, the engagement portioncan form or define a third surface or third limb-facing surface (i.e., the third limb-facing surface). The third limb-facing surfacecan be adjacent to and/or face a lateral surface of the limb (e.g., a side surface of the limb that is disposed furthest from the cam). Any combination of the first, second, or third limb-facing surfaces,,can extend perpendicular relative to one another.

andshow an axlefor an archery bow. The axlecan have one or more features that enable the axleto couple to or otherwise engage one or more portions of the member. For example, the axlecan include one or more channels or groovesA,B located or positioned on the axleto receive at least the nesting featureof the member. In some examples, each of the groovesA,B can extend around a circumference of the axle. While the nesting featureis disposed within the grooveA,B of the axle, a potential thrust load on the cam bearing can be mitigated or eliminated by transferring compressive loading from the member, through the nesting feature, to the axle. As such, while inserted on the axle, the membercan be prevented from sliding or translating along the axle due to an interference formed between the nesting featureand the grooveA,B. Each of the distal ends of the axlecan include a feature for affixing a fastener (e.g., a bolt, e-clip, etc.) to the axle. For example, the axlecan include threaded aperturesformed at the distal ends of the axle.

show first and second membersA,B affixed or otherwise coupled to the axle. The first and second membersA,B can be substantially similar to, and can include some or all of the features of the membersA,B,. For example, each of the membersA,B can include respective shim portionsA,B, intermediate portionsA,B, and engagement portionsA,B. The shim portionA can define a first end of the memberA contacting the axleat a first location. The engagement portionA can define a second end of the memberA contacting the axleat a second location. The first location can be spaced a distance from the second location along a length of the axle. The distance can be at least equivalent to a width of a limb (e.g., the first limbA). The shim portionB can define a first end of the memberB contacting the axleat a third location. The engagement portionB can define a second end of the memberB contacting the axleat a fourth location. The third location can be spaced a distance from the fourth location along a length of the axle. The distance can be at least equivalent to a width of a limb (e.g., the second limbB).

In some examples, the first memberA can be coupled to the axle, for example, the shim portionA can clamp or clip over the axle. Additionally, or alternatively, the nesting featurecan clamp or clip within the grooveA to retain the first memberA to the axle. In some examples, the engagement portionA can additionally, or alternatively, facilitate coupling the first memberA to the axle. For example, a fastener (not shown) can be inserted through the aperturewithin the engagement portionA of the first memberA and can be threadably received within the threaded aperture.

In some examples, the second memberB can be coupled to the axle, for example, the shim portionB can clamp or clip over the axle. Additionally, or alternatively, the nesting featurecan clamp, clip, or otherwise engage within the grooveB to retain the second memberB to the axle. In some examples, the engagement portionB can additionally, or alternatively, facilitate coupling the second memberB to the axle. For example, a fastenercan be inserted through the aperturewithin the engagement portionB of the second memberB and can be threadably received within the threaded aperture.

In some examples, the shim portionA can locate the cam a distance from a first end of the axleand the engagement portionA can couple the memberA to the first end of the axle. The distance can be defined as spanning between the lateral edges of the memberA (e.g., the engagement portionA and the shim portionA). In some examples, the shim portionB can locate the cam a distance from a second end of the axleand the engagement portionB can couple the memberB to the second end of the axle(e.g., the engagement portionB and the shim portionB). In other words, the cam can be disposed at a location between the first and second ends on the axlethat is defined by the relative widths of the membersA,B.

In some examples, the first and second membersA,B can be swappable on the axle or otherwise repositioned on the axleto vary a location a cam is retained on the axle(e.g., between the first and second membersA,B). In other words, the position the cam is retained on the axlecan be manipulated by a spacing associated with each of the first and second membersA,B. Due to respective tensions within one or more cables and a bowstring of the archery bow, the cam can be biased to lean or tilt the axle. This lean or tilt can affect the shooting plane of the archery bow and thereby influence the accuracy of the archery bow. By repositioning or swapping the first and second membersA,B, the lean or tilt of the axleexerted by the cam can be mitigated or modified to improve shooting characteristics of the archery bow.

shows the first and second membersA,B in a first state or first configuration on the axlewherein the first memberA is coupled to a first sideA of the axleand the second memberB is coupled to a second sideB of the axle. In some examples, the first memberA has a first spacing featureA having a first thickness and the second memberB has a second spacing featureB having a second thickness different from the first thickness.shows the first and second membersA,B in a second state or second configuration on the axlewherein the first memberA is coupled to the second sideB of the axleand the second memberB is coupled to the first sideA of the axle. Due to the relative difference between the first and second thicknesses of the first and second spacing featuresA,B, a cam can be disposed on the axleat different lateral positions dependent on which sides of the axle(e.g., first and second sidesA,B) the first and second membersA,B are disposed. For example, in the first state or first configuration (see) the cam can be disposed relatively closer to the first sideA of the axlebecause the relatively larger second spacing featureB of the second memberB is spacing the cam further from the second sideB of the axle. Conversely, in the second state or second configuration (see) the cam can be disposed relatively closer to the second sideB of the axlebecause the relatively larger second spacing featureB of the second memberB is spacing the cam further from the first sideA of the axle.

shows another example embodiment of a membercapable of being affixed to an axle and/or a limb of an archery bow to displace or locate a cam of the archery bow relative to the limb. In some examples, the membercan include one or more portions, such as, a shim portion, an intermediate portion, and/or an engagement portion. In some examples, one or more of these portions can be integrally formed from a continuous material, such as, a singular or unitary molded or machined component. In some examples, one or more of these portions can be discretely formed and thereafter welded, adhered, fastened, or otherwise coupled together to form the member.

Each of the portions (e.g., shim portion, intermediate portion, and engagement portion) can be similar to, and can include some or all of the features of the portions (e.g., shim portion, intermediate portion, and engagement portion) of the membersA,B,. For example, the shim portioncan include a spacing feature. The spacing featurecan be arranged and positioned on the shim portionsuch that the spacing featureis the only section of the shim portionthat contacts an inner race of a cam bearing leaving the remainder of the cam bearing to freely rotate about the axle. In some examples, as shown in, the spacing featurecan define or form a section of the shim portionthat is relatively thicker or wider than a section of the shim portiondisposed adjacent the intermediate portion. In other words, the spacing featurecan extend or protrude from a lateral surfaceof the shim portionto space or displace the cam from the lateral surface.
