Unconventional compact compound bow

摘要

The device of the present invention employs a riser, bow limbs, and bowstring to shoot an arrow. The employed features are positioned horizontally relative to the ground and generally perpendicular to the device handle when in use. The device handle may be hinged, and is hinged in the same plane as the riser, bow limbs, and bowstring. The device handle is ambidextrous and may include an arm brace. The device handle may be adjusted to alter draw length, and the device limb pockets may be adjusted to alter draw weight. The device is completely user-adjustable, compact, and lightweight.

1. A mechanical projectile device comprising:
a top pair of flexible members and a bottom pair of flexible members, each flexible member having a first end and a second end; a cam pulley system including cam pulleys and at least one cable; a bowstring including a nock point; a handle including a top end a bottom end, wherein the top end of the handle is connected to a yoke and the bottom end of the handle is connected to an arm brace; and a horizontal structural riser including:
a pair of pivot bars including a left pivot bar and a right pivot bar, each pivot bar having a top, a bottom, a front end, a back end, and two sides;a pair of front mounting brackets including a left front mounting bracket and a right front mounting bracket, wherein the front end of the left pivot bar is attached to the left front mounting bracket and the front end of the right pivot bar is attached to the right front mounting bracket;a pair of back mounting brackets including a left back mounting bracket and a right back mounting bracket, wherein the back end of the left pivot bar is attached to the left mounting bracket and the back end of the right pivot bar is attached to the right mounting bracket;a top hexagonal riser plate having an inside, an outside, a front half, a back half, a top, and a bottom;a bottom hexagonal riser plate having an inside, an outside, a front half, a back half, a top, and a bottom, wherein the bottom hexagonal riser plate is parallel to the top hexagonal riser plate and the top of the bottom hexagonal riser plate faces the bottom of the top hexagonal riser plate; wherein the pair of front mounting brackets are perpendicularly and symmetrically affixed to the front half of the top hexagonal riser plate on the inside of the top hexagonal riser plate and the pair of front mounting brackets are perpendicularly and symmetrically affixed to the front half of the bottom hexagonal riser plate on the inside of the front half of the bottom hexagonal riser plate; wherein the pair of back mounting brackets are perpendicularly and symmetrically affixed to the back half of the top hexagonal riser plate on the inside of the top hexagonal riser plate and the pair of back mounting brackets are perpendicularly and symmetrically affixed to the back half of the bottom hexagonal riser plate on the inside of the back half of the bottom hexagonal riser plate; wherein the top of each pivot bar faces the bottom of the top hexagonal riser plate and the bottom of each pivot bar faces the top of the bottom hexagonal riser plate; wherein each pivot bar includes a multiplicity of evenly spaced holes disposed between the two sides of each pivot bar; wherein the first end of each flexible member of the top pair of flexible members is affixed to the front half of the top hexagonal riser plate on the outside of the top hexagonal riser plate; wherein the first end of each flexible member of the bottom pair of flexible members is affixed to the front half of the bottom hexagonal riser plate on the outside of the bottom hexagonal riser plate; wherein the cam pulleys are rotationally affixed between the top pair of flexible members and the bottom pair of flexible members via affixation between the second ends of each of the flexible members; wherein the at least one cable is wrapped around at least a portion of the cam pulleys; wherein the bowstring is wrapped around at least a portion of the cam pulleys; wherein the yoke is pivotally mountable between the pair of pivot bars via the multiplicity of evenly spaced holes on each pivot bar such that the handle is adjustable among a plurality of positions via movement of the yoke wherein the multiplicity of evenly spaced holes on each pivot bar includes at least a first hole and a last hole on each pivot bar; wherein the first hole on each pivot bar is positioned farthest away from the nock point on the bowstring; wherein the last hole on each pivot bar is positioned closest to the nock point on the bowstring; wherein the mechanical projectile device provides for a variety of draw lengths via horizontal movement of the yoke between the pair of pivot bars, wherein the variety of draw lengths includes a longest draw length and a shortest draw length; wherein the longest draw length for the mechanical projectile device is achieved by pivotally mounting the yoke in the first hole on each pivot bar; wherein the shortest draw length for the mechanical projectile device is achieved by pivotally mounting the yoke in the last hole on each pivot bar; and wherein the arm brace is rotatable about the bottom end of the handle from a home position through a plurality of positions which accommodate left-handedness and right-handedness, wherein when the arm brace is in the home position, the handle, the arm brace, the yoke, and the horizontal structural riser are symmetrical relative to a vertical plane which bisects the handle, the arm brace, the yoke, and the horizontal structural riser.
