Abstract
A projectile launcher including a frame having a grip and defining a projectile axis, a drawstring hub rotatable mounted to the frame and defining a central axis perpendicular to the projectile axis and positioned a fixed distance from the projectile axis, a drawstring being attached to the drawstring hub so that movement of the drawstring results in the rotation of the drawstring hub about the central axis, a limb coupled to the frame and extending along a vertical limb plane, and a power cable coupled to the limb and the drawstring hub so that rotation of the drawstring hub about the central axis draws the limb closer to the central axis.
Claims20
A projectile launcher, comprising;
- a frame having a pistol grip and defining a projectile axis;
- a drawstring hub rotatable mounted to the frame and defining a central axis perpendicular to the projectile axis and positioned a fixed distance from the projectile axis;
- a drawstring being attached to the drawstring hub so that movement of the drawstring results in rotation of the drawstring hub about the central axis;
- a limb support coupled to the frame;
- a limb secured by the limb support and extending along a vertical limb plane;
- and
- a power cable coupled to the limb and the drawstring hub so that rotation of the drawstring hub about the central axis draws the limb closer to the central axis,
- wherein the pistol grip is positioned between the central axis and the limb support along the projectile axis.
A projectile launcher, comprising:
- a drawstring repositionable between a drawn position and an undrawn position;
- a frame including a first frame member and a second frame member, the frame defining a projectile axis;
- a power wheel coupled to the frame and rotatable in a first direction and a second direction about a central axis, the central axis spaced apart from the projectile axis;
- a limb coupled to the frame by a limb support, the limb extending in a vertical limb plane substantially perpendicular to the central axis and defining a limb end, the limb vertically repositionable when the drawstring is moved between the drawn position and the undrawn position so that the limb end is closer to the power wheel when the drawstring is in the drawn position than when the drawstring is in the undrawn position;
- and
- a grip coupled to the frame between the central axis and the limb support.
A projectile launcher, comprising:
- a drawstring movable between a drawn position and an undrawn position, the drawstring having a first end and a second end;
- a frame including a grip, a first frame member, and a second frame member, the frame defining a projectile axis;
- a power wheel coupled to the frame and rotatable in a first direction and a second direction about a central axis offset from and perpendicular to the projectile axis;
- a drawstring guide frame coupled to the frame rearward of the grip along the projectile axis;
- and
- a drawstring guide coupled to the drawstring guide frame and configured to guide the drawstring across the projectile axis between the first end and the second end of the drawstring.
