Description

FIELD OF THE INVENTION

The present invention relates to archery bows, and more specifically to an archery bow that includes a handle with brace rod receivers that can be coupled with and is moveable along brace rods attached to the archery bow.

BACKGROUND OF THE INVENTION

Archery bows are configured with a bow handle, a bow frame, and opposing limbs extending outward from the bow frame and configured to accommodate a drawstring. When an archer pulls back on the drawstring to full draw position, typically the draw length is approximately the length of the archer's arm so that the drawstring is about even with the archer's lips. The draw length and appropriate grip angle for different sized archers will vary according to the individual archer's particular body type and arm length.
Most archery bows have an adjustable draw length to accommodate differing draw lengths of individual archers. On a compound bow that utilizes eccentric wheels, or cams, to attach the drawstring to the limbs of the bow, the draw length is changed by changing the attachment of the drawstring to the cams. A limb compressor is needed to release the drawstring from the limbs and to prevent any damage to the bow. For this reason, the draw length of a bow is not easily adjusted by the archer. The archer generally must take the bow to a technician with the proper equipment for adjusting draw length.
A general goal of archery bow designs is to increase the speed and accuracy of an arrow fired from an archery bow. Having a properly adjusted archery bow so that the draw length and grip angle of the bow is configured to accommodate an individual archer's body type and draw length allows the archer to achieve full draw on the drawstring and transfer maximum force from the drawstring to the arrow when the drawstring is released and energy is transferred from the drawstring to the arrow. In light of the above discussed goals, it would be desirable to develop an archery bow in which the draw length and grip angle is more easily adjustable.

FIG. 1 illustrates an embodiment of an archery bow, hereinafter archery bow 10, with a draw length and grip angle capable of being adjusted to accommodate an individual archer's draw length and grip angle. Exemplary archery bow 10 comprises a pair of limbs 12 a and 12 b attached to a bridged handle 14. Archery bow 10 defines a major longitudinal axis “X” and a transverse axis “Y” extending perpendicularly to the longitudinal axis “X”. Bow 10 further comprises a cable 16, for example, a string or drawstring, which extends between first and second limbs 12 a and 12 b. Brace rods 18 a and 18 b may be detachably joined to bridged handle 14 along transverse axis “Y”. Handle grip 20 is positioned longitudinally and forwardly displaced along axis “Y” from the bridged handle 14. Handle grip 20 comprises a first end 22 a and a second end 22 b opposed to first end 22 a. Brace rod receivers 24 a and 24 b are detachably connected to handle grip ends 22 a and 22 b and are configured to receive an archery bow brace rod 18.
Axis “Z” extends perpendicularly from axis “X” and axis “Y”. Bridged handle 14 is configured so that a portion of the bridged handle 14 is displaced from the major longitudinal axis “X” along axis “Z” and is substantially parallel to major longitudinal axis “X”.
The bridged handle 14 is further configured with at least two apertures 28 and 30 positioned along bridged handle 14. Brace rod 18 may be configured with threaded extension 32 extending through brace rod 18, threaded extension 32 configured to matingly receive a threaded nut 34, for example, but not limited to, a barrel nut. Apertures 28 and 30 are configured to accommodate threaded extension 32 and threaded nut 34. Apertures 28 and 30 are further configured with an outer aperture portion 36 and an inner aperture portion 38, with inner aperture portion 38 being forwardly positioned along the “Y” axis within bridged handle 14, with the direction “forwardly” being defined as the direction in which an arrow would be launched from bow 10. Brace rod 18 may be tightened to bridged handle 14 by coupling the threaded extension 32 and threaded nut 34 with aperture 28 or 30, forwardly positioning threaded extension 32 and threaded nut 34 along axis “Y” into inner aperture portion 38 within bridged handle 14 and then tightening brace rod 18 to bridged handle 14 by rotating brace rod 18 so that threaded extension 32 matingly receives threaded nut 34 until brace rod 18 is secured against bridged handle 14. Apertures 28 and 30 may be further configured so that aperture 28 is located on the bridged handle 14 along the major longitudinal axis “X” and aperture 30 is located on the displaced portion of bridged handle 14 along axis “Z” and further configured so that aperture 30 is longitudinally displaced from aperture 28 along the bridged handle 14.
In alternate embodiments of the present invention, apertures 28 and 30 may be located at different points along bridged handle 14, and further configured so that inner aperture portion 38 is displaced in a variety of directions relative to the longitudinal “X” axis, for example, but not limited to, substantially upward or downward along the “X” axis within the bridged handle 14 of archery bow 10.
In an embodiment of the present invention variable positioning of a brace rod receiver 24 along brace rod 18 is permitted relative to archery bow 10. More specifically, the embodiment of the present invention permits displacement of a brace rod receiver 24 across a range of variable positions determined by an archer's placement of the brace rod receivers 24 along the brace rods 18. Brace rod receivers 24 a and 24 b may be detachably coupled to brace rods 18 a and 18 b, allowing handle grip 20 to be variably positioned along the brace rods 18 a and 18 b so that the archer may selectably determine the placement of the handle grip 20. This allows the archer to position handle grip 20 along brace rods 18 a and 18 b to correspond to the individual archer's grip angle and draw length when cable 16 of bow 10 is fully drawn to shoot an arrow. In one embodiment of the invention, handle grip 20 is comprised of a body 40 positioned longitudinally between the first end and second end 22 a and 22 b of handle grip 20. Handle grip 20 is further configured with a handgrip 42 configured to be grasped by an archer's hand. Handle grip ends 22 a and 22 b are further configured with an aperture 48 configured to accommodate a fastener 46 which may comprise, but is not limited to, for example, a pin, a screw or bolt or combination thereof. Brace rod receivers 24 a and 24 b may be fastened to the handle grip 20 and secured by fastener 46. The archer may detachably couple the brace rod receivers 24 a and 24 b along the archery bow brace rods 18 a and 18 b. Once the brace rod receivers 24 a and 24 b have been detachably coupled along archery bow brace rods 18 a and 18 b, the fastener 46 may be tightened to prevent further movement along the brace rods 18 a and 18 b.
In an alternate embodiment of the present invention, a single brace rod 18 may be coupled with an aperture 28 located along bridged handle 14. Brace rod 18 may be detachably coupled with a brace rod receiver 24 that may be detachably connected to handle grip 20 at various points along handle grip 20. Handle grip 20 may be further configured so that a single brace rod receiver 24 is connected to handle grip 20 and detachably coupled with a single brace rod 18.
In an alternate embodiment, second end 22 b of handle grip 20 further comprises a slotted aperture 48 configured so that fastener 46 of brace rod receiver 24 may be selectably positioned across a range of positions along the slotted aperture 48 and fastener 46 may be fastened at a position chosen by the archer along slotted aperture 48, thereby increasing or decreasing the angle of handle grip 20 and hand grip 42 relative to bridged handle 14 of archery bow 10. In an alternate embodiment of the invention, archery bow handle grip 20 further comprises a plurality of cavities 50 configured to receive an archery bow sight window 52. An archer may then selectably determine the position of the sight window 52 depending upon placement in cavities 50.
