FIELD

This disclosure relates to the field of cable guards for archery bows. More particularly, this disclosure relates to a roller cable guard that enables quick and easy adjustability of the position of the cable guard so that the cable guard may be readily adjusted to desirably clear the fletching on the arrow.

BACKGROUND

Compound bows often include a cable guard to hold the cables out of the path of the arrow. One popular type of cable guard is a roller cable guard that uses one or more rollers or pulleys to receive the cables of the bow. Conventional cable guards of this type are installed and often positioned to maintain the cables of the bow to just clear the fletching on an arrow of the largest standard size. The fletching on the arrow is provided to stabilize the flight of the arrow and is generally present as fins, vanes, or the like on the distal end (remote from the point) of the arrow.

Conventional roller cable guards work suitably with arrows of a single type having substantially uniformly dimensioned fletching. However, in the event the archer desires to shoot arrows having different fletching dimensions, the position of the cable guard as set for the previous fletching can be disadvantageous. For example, insufficient arrow clearance will cause contact between the cables and the fletching and detrimentally affect the flight of the arrow. Alternatively, excessive arrow clearance may cause the cables to track incorrectly on the wheels and/or creates unnecessary side torque on the wheels which can adversely affect bow action. Any of these can potentially result in serious personal injury and/or damage to the bow, and are otherwise disadvantageous. Conventional cable guards may be re-installed to be suitable with differently sized arrows, but such is cumbersome and time consuming.

Accordingly, what is desired is an archery cable guard that enables quick and easy adjustability of the position of the cable guard so that the cable guard may be readily adjusted to desirably clear the fletching on the arrow.

SUMMARY

The above and other needs are met by an adjustable cable guard for archery bows. In one embodiment, the guard includes a guard holder and a cable guard held by the guard holder to engage a cable of the bow to maintain the cable a predetermined distance from a drawstring of the bow.

The guard holder includes a body having an open ended clamping groove having a length axis and a bifurcating slit that extends from the clamping groove into the body of the holder. The width of the clamping groove may be changed by application and removal of a compressive force to the slit.

The cable guard includes a surface to bear against the cable of the bow and a tongue located to be matingly and slidingly received by the clamping groove of the guard holder. The tongue may move along the length of the groove to enable adjustment of the position of the cable guard relative to the clamping groove to position the cable at a predetermined spacing from the drawstring of the bow. The position of the tongue within the groove may be locked against movement by compressing the slit to bear surfaces of the clamping groove against surfaces of the tongue to clamp the tongue against movement and thereby maintain the cable at the predetermined spacing from the drawstring of the bow.

 DETAILED DESCRIPTION

With reference to FIG. 1, there is shown an adjustable roller guard system 10 for use with a compound archery bow 12 according to a preferred embodiment of the disclosure.

The bow 12 includes a handle or riser 20, limbs 22a and 22b, cams or wheels 24a and 24b, cable portions 26a and 26b, and drawstring 28.

The adjustable roller guard system 10 includes a riser mount 30, a rod 32, a guard holder 34, and a cable guard 36 having rollers 38a and 38b. For low weight and stiffness, the riser mount 30, rod 32, holder 34, and guard 36 may be made of carbon fiber or the like.

The system 10 is configured so that the lateral position of the cable guard 36 may be laterally adjusted along a lateral axis LA of the roller guard system 10 that is substantially perpendicular to the length axis of the rod 32 (FIG. 3) to maintain the cable portions 26a and 28a of the bow 12 at a desired lateral spacing LS from the drawstring 28 (FIG. 5). In this regard, the desired lateral spacing LS is typically a spacing selected so that the cable portions 26a and 26b just clear the fletching on an arrow being shot by the bow 12 using the drawstring 28. For example, a clearance of from about 1/16 to about 5/16 of an inch is generally desired.

The rod 32 may be mounted directly to the riser 20 as by apertures or the like located on the riser 20, but it is preferred to utilize the mount 30. The mount 30 serves to stiffen the connection between the rod 32 and the riser 20 and enables quick attachment and detachment of the guard system 10 to the bow 12. In an embodiment, the rod 32 can have a first portion or projection 31 (FIG. 2) extending from the mount 30 and configured to be inserted into an aperture located on the riser 20 and a second portion or extension 33 (FIG. 2) connecting the mount 30 to the guard holder 34. The guard holder 34 is frictionally retained on the distal end of the rod 32 and the cable guard 36 is frictionally retained on the guard holder 36 34. The rollers 38a and 38b are rotationally mounted on the cable guard 36.

The guard holder 34 and the cable guard 36 are configured to enable adjustment of the position of the cable guard 36 relative to the guard holder 34. As shown in FIGS. 3 and 5, this adjustment is along a lateral adjustment axis LA. To enable the adjustment, the guard holder 34 is configured to movably receive a portion of the cable guard 36 for adjustment of the position of the cable guard 36, and to be clampable to hold the cable guard 36 against movement once it is desirably located.

With reference to FIG. 6, the guard holder 34 includes a distal end configured to define an open ended clamping groove 40 and a bifurcating slit 42 that extends from the clamping groove 40 into a distal body 44 of the holder 34. The clamping groove 40 may preferably have a trapezoidal cross-sectional shape. The groove 40 is preferably open on each end, but may be open on just one end. The slit 42 enables adjustment of the width of the clamping groove 40.

The width of the clamping groove 40 may therefore be adjusted from a minimal width by fully compressing the slit 42 or to a maximum width by having no compression applied to the slit 42, in which case the clamping groove 40 may expand in width up to the flexibility or elasticity of the material used to provide the holder 34. As will be observed, when the guard holder 34 is installed on the rod 32 with the system 10 installed on the bow 12, the length axis of the clamping groove 40 corresponds to the lateral adjustment axis LA.

Compressive force may be applied to the slit 42, for example, by providing a bore 46 into the distal body 44 that extends substantially perpendicular to and spans the slit 42 and utilizing a fastener extended into the bore 46 to compress the slit 42. For example, a terminal end of the bore 46 may be threaded and threadably receive a fastener, such as a bolt 48, having a head that engages a portion of the distal body 44 opposite the terminal end 46 of the bore 46. Thus, tightening the bolt 48 will compress the slit 42.

With reference to FIG. 7, the cable guard 36 includes: (i) a support 36a that supports rollers 38a, 38b, wherein the support 36a has a surface 37 located opposite of the rollers 38a, 38b; and (ii) a protrusion or tongue 50 extending from the surface 37, wherein the tongue 50 has a top surface 50a, and the tongue 50 is configured to be matingly and slidingly received by the clamping groove 40. As seen, the tongue 50 is of substantially the same cross-sectional shape as the groove 40 and may be slidingly inserted from one of the open ends of the groove 40.

As situated, the tongue 50 may move along the length of the groove 40, which enables the tongue to move along the lateral adjustment axis LA, thus enabling adjustment of the cable guard 36 along the lateral adjustment axis LA. The position of the tongue 50 within the groove 40 may be locked against movement by compressing the slit 42 such as described above to bear surfaces of the clamping groove 40 against surfaces of the tongue 50 to clamp the tongue 50 in a desired position.

Thus, in this manner, the lateral position of the cable guard 36 may be adjusted along the lateral axis LA to position and maintain the cable portions 26a and 28a of the bow 12 at the desired lateral spacing LS from the drawstring 28 and the fletching of the arrow. In the event the archer desires to change to an arrow having different fletching dimensions, the position of the cable guard 36 may be readily changed.

In alternate embodiments of the invention, the tongue may be located on the holder and the groove and slit located on the guard. Additionally, other mechanisms may be used which allow for lateral adjustment of a cable guard relative to the position of a holder.
