Abstract
An arrow rest assembly is connected to an archery bow so that an arrow rest is: (i) positioned to support the shaft of an arrow nocked and ready for drawing or drawn and ready for shooting, (ii) positioned to support the shaft of the arrow during an early portion of shooting of the arrow by the bow, and (iii) to allow substantially unimpeded passage of the fletching of the arrow during only the latter portion of shooting of the arrow by the bow. The arrow rest assembly exerts only substantially negligible force on any cable of the bow when the bow is drawn.
Claims24
An apparatus comprising:
- a support member;
- a rotating member rotatably mounted on the support member at a first pivot point of the support member, the rotating member being biased toward a rest position against a rotation stop;
- a lever rotatably mounted on the support member at a second pivot point of the support member, the lever comprising first and second lever arms and being biased toward a cocked position;
- and
- a linkage coupling the first lever arm and the rotating member,
- wherein the support member, the rotating member, the lever, and the linkage are arranged so that:
- with only substantially negligible force exerted on the second lever arm, the lever assumes its cocked position in response to its bias;
- in response to an external force exerted on the second lever arm to rotate the lever away from its cocked position against its bias, the first lever arm urges the linkage against the rotating member so as to rotate the rotating member away from its resting position against its bias;
- and
- in response to the rotating member being rotated against its bias by the linkage past a release position, the linkage allows the rotating member to rotate to its resting position in response to its bias.
An archery bow comprising:
- oppositely projecting first and second bow limbs;
- a first pulley member pivotably connected to the first bow limb;
- a second pulley member pivotably connected to the second bow limb;
- a draw cable engaged with the first and second pulley members;
- at least one additional cable engaged with the first or second pulley member;
- and
- an arrow rest assembly comprising (i) a support member, (ii) a rotating member, (iii) an arrow rest connected to the rotating member, (iv) a lever comprising first and second lever arms, and (v) a linkage coupling the first lever arm and the rotating member,
- wherein:
- the rotating member is rotatably mounted on the support member at a first pivot point of the support member, the rotating member being biased toward a rest position against a rotation stop;
- the lever is rotatably mounted on the support member at a second pivot point of the support member, the lever being biased toward a cocked position;
- the support member, the rotating member, the lever, and the linkage are arranged SO that (i) with only substantially negligible force exerted on the second lever arm, the lever assumes its cocked position in response to its bias, (ii) in response to an external force exerted on the second lever arm to rotate the lever away from its cocked position against its bias, the first lever arm urges the linkage against the rotating member so as to rotate the rotating member away from its resting position against its bias, and (iii) in response to the rotating member being rotated against its bias by the linkage past a release position, the linkage allows the rotating member to rotate to its resting position in response to its bias;
- the support member is connected to the bow so that the arrow rest is positioned (i) to support, with the rotating member in its rest position, the shaft of an arrow nocked and ready for drawing or drawn and ready for shooting, and (ii) to allow, with the rotating member at or past its release position, substantially unimpeded passage of the fletching of the arrow during shooting of the arrow by the bow;
- and
- the second lever arm is arranged to be connected to the additional cable of the bow so that (i) the additional cable exerts only substantially negligible force on the second lever arm with the bow drawn, and (ii) the cable exerts a force on the second lever arm, during only the latter portion of a time interval corresponding to shooting of the arrow by the bow, that urges the linkage against the rotating member so as to rotate the rotating member away from its resting position and past its release position against its bias.
A method comprising:
- (a) rotatably mounting a rotating member on a support member at a first pivot point of the support member, and biasing the rotating member toward a rest position against a rotation stop;
- (b) rotatably mounting a lever on the support member at a second pivot point of the support member, and biasing the lever toward a cocked position, the lever comprising first and second lever arms;
- (c) coupling the first lever arm and the rotating member with a linkage;
- and
- (d) arranging the support member, the rotating member, the lever, and the linkage so that (i) with only substantially negligible force exerted on the second lever arm, the lever assumes its cocked position in response to its bias, (ii) in response to an external force exerted on the second lever arm to rotate the lever away from its cocked position against its bias, the first lever arm urges the linkage against the rotating member so as to rotate the rotating member away from its resting position against its bias, and (iii) in response to the rotating member being rotated against its bias by the linkage past a release position, the linkage allows the rotating member to rotate to its resting position in response to its bias.
A method comprising:
- (a) pivotably connecting a first pulley member to a first bow limb of an archery bow;
- (b) pivotably connecting a second pulley member to a second bow limb of the archery bow;
- (c) engaging a draw cable with the first and second pulley members;
- (d) engaging at least one additional cable with the first or second pulley member;
- and
- (e) connecting an arrow rest assembly to the bow, the arrow rest assembly comprising (i) a support member, (ii) a rotating member, (iii) an arrow rest connected to the rotating member, (iv) a lever comprising first and second lever arms, and (v) a linkage coupling the first lever arm and the rotating member,
- wherein:
- the rotating member is rotatably mounted on the support member at a first pivot point of the support member, the rotating member being biased toward a rest position against a rotation stop;
- the lever is rotatably mounted on the support member at a second pivot point of the support member, the lever being biased toward a cocked position;
- the support member, the rotating member, the lever, and the linkage are arranged So that (i) with only substantially negligible force exerted on the second lever arm, the lever assumes its cocked position in response to its bias, (ii) in response to an external force exerted on the second lever arm to rotate the lever away from its cocked position against its bias, the first lever arm urges the linkage against the rotating member so as to rotate the rotating member away from its resting position against its bias, and (iii) in response to the rotating member being rotated against its bias by the linkage past a release position, the linkage allows the rotating member to rotate to its resting position in response to its bias;
- the support member is connected to the bow so that the arrow rest is positioned (i) to support, with the rotating member in its rest position, the shaft of an arrow nocked and ready for drawing or drawn and ready for shooting, and (ii) to allow, with the rotating member at or past its release position, substantially unimpeded passage of the fletching of the arrow during shooting of the arrow by the bow;
- and
- the second lever arm is arranged to be connected to the additional cable of the bow so that (i) the additional cable exerts only substantially negligible force on the second lever arm with the bow drawn, and (ii) the cable exerts a force on the second lever arm, during only the latter portion of a time interval corresponding to shooting of the arrow by the bow, that urges the linkage against the rotating member so as to rotate the rotating member away from its resting position and past its release position against its bias.
