1. Field of the Invention
This invention relates to an archery bow riser having a moveable arrow rest that can be generally aligned with a longitudinal axis of the archery bow riser, to reduce or minimize a rotational effect of an archer's forehand when drawing a bow string.
2. Discussion of the Related Art
Many conventional arrow rests are connected to a bow riser with a bracket. The bracket can adjoin the arrow rest to one of many different types of bow risers, using a mounting hole, such as sized and positioned according to an Archery Manufacturers and Merchant's Organization (“AMO”) specification. The bracket includes a length or a moment arm that offsets the arrow rest from and thus not aligned with a longitudinal axis of the bow riser. This offset makes aiming at a target more difficult for an archer.
This invention provides an improved archery bow riser that aligns a moveable arrow rest with a longitudinal axis in order to reduce or minimize a rotational effect of an archer's forehand, such as caused by drawing a bow string.
An archery bow riser according to this invention has a grip, an arrow shelf and a cavity. The archery bow riser can have a longitudinal axis passing through the grip. The longitudinal axis is an imaginary line or a reference line that identifies an axis of rotation of the archery bow riser when the grip is held by an archer. An arrow rest can be mounted directly or indirectly to the riser. The arrow rest can be a moveable arrow rest having a start position and a launch position. A support area of the arrow rest can be positioned above the arrow shelf and substantially aligned with the longitudinal axis in the start position. The arrow rest can be moveably mounted within the cavity, to move into and away from launch position.
Other objects and advantages will be apparent to those skilled in the art from the following detailed description taken in conjunction with the appended claims and drawings.
The above and other features and objects of this invention will be better understood from the following detailed description taken in view of the drawings wherein:
As used throughout this specification and in the claims, the term arrow rest is intended to relate to and to be interchangeable with the terms drop-away arrow rest, move-away arrow rest, fall-away arrow rest and/or any other arrow rest or other similar device for resting or supporting a shaft of a projectile, including an arrow and/or crossbow bolt. Mizek et al., U.S. Pat. No. 6,782,881 and Mizek, U.S. Pat. No. 7,331,338, the entire teachings of both of which are incorporated into this specification by reference, teach different technical features and functions of arrow rests that move away from an arrow shaft when the arrow shaft is discharged from an archery bow.
The scope of this invention is intended to include archery bows, crossbows, or any other device that launches or propels a projectile.
In the embodiment shown in
According to certain embodiments of this invention, arrow rest 40 can be mounted to archery bow riser 30. Arrow rest 40 can be mounted to archery bow riser 30 with a mechanical mounting, including but not limited to a mechanical connection, such as a threaded connection and/or an adhesive connection. Alternatively, arrow rest 40 can be integrally formed with archery bow riser 30. In certain embodiments, arrow rest 40 is a moveable arrow rest that includes a start position, such as shown in
Referring to
According to some embodiments of this invention, support 42 generally aligns with longitudinal axis 50 when arrow rest 40 is in the start position. Longitudinal axis 50 is an imaginary line or reference line that runs vertically within or through grip 32. Longitudinal axis 50 can be an axis of rotation about which archery bow riser 30 rotates while in an archer's forehand grip. When the archer draws a bow string, a significant force is exerted and thus the archer's forehand is under significant tension which can cause movements and/or rotations about longitudinal axis 50. The movements and/or rotations are multiplied as a mathematical function of a distance between longitudinal axis 50 and support 42. This invention reduces or minimizes the multiplication factor by shortening or eliminating the distance between longitudinal axis 50 and support 42, in some embodiments of this invention by positioning support 42 to be substantially and/or generally aligned with longitudinal axis 50.
