Abstract

A layout device is used with an archery bow. The bow has a riser and a pair of flexible limbs extending oppositely from the riser. The layout device includes a frame with an arm configured for coupling with the riser. The arm has a longitudinal axis. An axial adjustment mechanism is carried by the frame, and is movable relative to the frame in a direction generally orthogonal to the longitidinal axis. A laser is carried by the axial adjustment mechanism. The laser is rotatable at least approximately 180° about a rotation axis extending generally orthogonal to the longitudinal axis.

Claims

1. A layout device for use with an archery bow, the bow having a riser, a pair of flexible limbs extending oppositely from the riser and a string extending between ends of the flexible limbs, said layout device comprising:

a frame including an arm configured for coupling with the riser, said arm having a longitudinal axis;

an axial adjustment mechanism carried by said frame, said axial adjustment mechanism being movable relative to said frame in a direction generally orthogonal to said longitidinal axis; and

a laser carried by said axial adjustment mechanism, said laser being rotatable at least approximately 180°

about a rotation axis extending generally orthogonal to said longitudinal axis, said rotational axis being between the string and the riser; and

wherein said laser aligns an arrow, at least one of said limbs and said string.

2. The layout device of claim 1, wherein said laser is rotatable 360°

about said rotation axis.

3. The layout device of claim 1, wherein said layout device includes an axial adjustment mechanism for adjusting an offset of said laser from said longitudinal axis.

4. The layout device of claim 3, wherein said frame is coupled with said riser, said axial adjustment mechanism being movable relative to said frame in a direction parallel to said rotation axis.

5. The layout device of claim 4, wherein said axial adjustment mechanism includes a coarse axial adjustment and a fine axial adjustment.

6. The layout device of claim 5, wherein said frame includes a cylindrical opening and said axial adjustment mechanism includes a cylinder axially within said opening.

7. The layout device of claim 6, wherein said coarse axial adjustment includes a ball and detent arrangement between said cylinder and said opening.

8. The layout device of claim 7, wherein said cylinder includes a plurality of axially spaced annular detents and said frame includes a biased ball in communication with said opening, said ball selectively engaging one of said plurality of annular detents.

9. The layout device of claim 6, wherein said fine axial adjustment includes a threaded adjustment.

10. The layout device of claim 9, wherein said cylinder includes a threaded opening and said fine axial adjustment includes a threaded rod within said threaded opening, said laser being connected with said threaded rod.

11. A layout device for use with an archery bow, the bow having a riser, a pair of flexible limbs extending oppositely from the riser and a string extending between ends of the flexible limbs, the bow also having a longitudinal axis, said layout device comprising:

a frame configured for coupling with the riser;

an axial adjustment mechanism carried by said frame, said axial adjustment mechanism being movable relative to said frame in a direction generally orthogonal to the longitidinal axis when said frame is coupled with the riser; and

a laser carried by said axial adjustment mechanism, said laser being rotatable at least approximately 180°

about a rotation axis extending generally parallel to the direction of movement of said axial adjustment mechanism, said rotational axis being between the string and the riser; and

wherein said laser aligns an arrow, at least one of said limbs and said string.

12. An archery bow assembly, comprising:

a bow having a riser, a pair of flexible limbs extending oppositely from said riser, said bow having a longitudinal axis;

a layout device coupled with said riser and a string extending between ends of said flexible limbs, said layout device including a laser which is rotatable at least approximately 180°

about a rotation axis generally orthogonal to said longitidinal axis, said rotational axis being between said string and said riser; and

wherein said laser aligns an arrow, at least one of said limbs and said string.

13. The archery bow of claim 12, wherein said laser is rotatable 360°

about said rotation axis.

14. The archery bow of claim 12, wherein said layout device includes an axial adjustment mechanism for adjusting an offset of said laser from said longitudinal axis, and a frame coupled with said riser, said axial adjustment mechanism being movable relative to said frame in a direction parallel to said rotation axis.

15. The archery bow of claim 14, wherein said axial adjustment mechanism includes a coarse axial adjustment and a fine axial adjustment.

16. The archery bow of claim 14, wherein said axial adjustment mechanism adjusts said offset along said rotation axis.

17. The archery bow of claim 12, wherein said laser includes an electrical power source which rotates with said laser during rotation.

18. The archery bow of claim 17, wherein said electrical power source is at least one battery.

19. A method of laying out an archery bow, comprising the steps of:

providing a bow including a riser, a pair of flexible limbs extending oppositely from said riser, a string, and an arrow rest;

mounting a layout device to said riser, said layout device including a laser which is rotatable 360°

about a rotation axis generally extending orthogonal to said longitidinal axis.

axially adjusting said laser relative to said rotation axis; and

selectively projecting a laser light beam from said laser onto each of said flexible limbs, said string, and said arrow rest to verify generally that each lie in a common plane.

20. The method of claim 19, wherein said bow further includes a cam wheel at a distal end of each said limb, and said selectively projecting step includes projecting said laser riser onto at least a portion of said cam wheel to verify that said portion of said cam wheel lies in said common plane.

21. The method of claim 19, wherein said bow includes an arrow engaged with each of said string and said arrow rest, and said selectively projecting step includes projecting said laser riser onto at least a portion of said arrow to verify that said portion of said arrow lies in said common plane.
