Abstract:

In the field of archery, draw length adjustment is currently accomplished by interchangeable cams or cam adjustment while the handgrip remains fixed. To accommodate for shorter draw lengths, smaller cams are used which can reduce arrow velocity and overall bow performance. The Great Equalizer is a riser system that can be incorporated into any archery bow design and consists of various fixed positions that utilizes a movable handgrip that can be locked in place at any of the positions to compensate for the bow user's draw length without having to adjust the cams that can inhibit a bow's performance.

BACKGROUND IF THE INVENTION

In the field of archery draw length adjustment is currently accomplished by interchangeable cams or cam adjustment. To accommodate for shorter draw lengths, smaller cams are used which can reduce arrow velocity and overall bow performance.

BRIEF SUMMARY OF THE INVENTION

The invention is a bow riser with an adjustable handgrip to compensate for the varying draw lengths of bow users without having to adjust cam size. All type bows using the invention would be designed to shoot the same arrow length for maximum arrow velocity no matter the archer's draw length. This infers that the bow manufacturer's performance specifications would remain constant for every user as the cams that provide power will not have to be altered.

This invention is a riser that has a set of varying fixed points that the handle can be moved to which adjusts for a user's draw length.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

FIG. 1A: This is a side view of the invention. The riser can be added to almost any bow design to allow handle to be moved to various fixed positions compensating for different draw lengths.

FIG. 1B: This is a rear view of the riser. It shows offset of riser from the frame to allow for hand clearance.

DETAILED DESCRIPTION OF THE INVENTION

The invention is a riser that takes the place of the currently used immobile archery bow handles. As seen in FIG. 1A the riser has a set of positions that the handle can be moved to and fixed in place. The size of the riser and material comprising it are entirely up to the bow manufacturer. The riser is offset from the bow frame as shown in FIG. 1B to allow for hand clearance.

Claims

1. The Great Equalizer is a riser system that can be incorporated into any archery bow design and consists of various fixed positions that utilizes a movable handgrip that can be locked in place at any of the positions to compensate for the bow user's draw length.
