IV. DETAILED DESCRIPTION

One or more embodiments of the invention are described below. It should be noted that these and any other embodiments are exemplary and are intended to be illustrative of the invention rather than limiting. While the invention is widely applicable to different types of systems, it is impossible to include all of the possible embodiments and contexts of the invention in this disclosure. Upon reading this disclosure, many alternative embodiments of the present invention will be apparent to persons of ordinary skill in the art.

This invention relates to the field of archery and the problem of setting up and aligning an archery bow and its attachments, and more specifically to an archery alignment device and method that accomplishes a faster, more convenient and more precise alignment by use of a plane of laser light or portion thereof.

FIG. 1 is a side perspective view of an archery bow including the laser plane alignment device of the present invention, in accordance with some embodiments. The laser plane alignment device is shown with the laser not activated.

In some embodiments, the archery bow 10 includes a riser 50, an upper flexible limb 20, a lower flexible limb 22, an upper wheel or cam 30, a lower wheel or cam 32, at least one string 40 and a sight 80. An arrow rest 60 is connected to the riser 50 to support a typical arrow (not shown) or in this preferred embodiment, the laser plane alignment device 90 of the present invention. The laser alignment device 90 has a device housing 100 much like an arrow shaft and an adapter 110 much like an arrow nock. The device housing 100 sits on the arrow rest 60 and connects to the bowstring 40 with the adapter 110 like a typical arrow.

FIG. 2 is a side perspective view of an archery bow including the laser plane alignment device of the present invention, in accordance with some embodiments. The laser plane alignment device is shown with the laser activated.

In some embodiments, the archery bow 10 includes a riser 50, an upper flexible limb 20, a lower flexible limb 22, an upper wheel or cam 30, a lower wheel or cam 32, at least one string 40 and a sight 80. An arrow rest 60 is connected to the riser 50 to support a typical arrow (not shown) or in this preferred embodiment, the laser plane alignment device 90 of the present invention. The laser alignment device 90 has a device housing 100 much like an arrow shaft and an adapter 110 much like an arrow nock. The device housing 100 sits on the arrow rest 60 and connects to the bowstring 40 with the adapter 110 like a typical arrow. When the laser alignment device 90 is activated, a sheet of laser light 160 is projected within the archery bow 10.

FIG. 3 is a side perspective view of a laser plane or portion thereof being generated with a fiber optic bundle and a laser beam source, in accordance with some embodiments.

In some embodiments, the laser plane 160 or portion thereof is generated from the laser beam source 140 striking the fiber optic bundle 120. The laser beam source 140 projects a laser beam 142 substantially orthogonal to the lens or fiber optic bundle 120, which generates a laser plane 160. This technology is taught by U.S. Pat. No. 5,898,809 issued Apr. 27, 1999 to John Taboada and John Martin Taboada. Further examples of devices and methods to generate a laser plane or portion thereof from a laser beam source can be found in the Taboada et. al. patent.

FIG. 4 is an exploded side perspective view of the laser plane alignment device of FIG. 1 and FIG. 2, in accordance with some embodiments.

In some embodiments, the fiber optic bundle 120 is connected to and positioned by a housing 130 wherein the laser beam source 140 projects a laser beam 142 substantially orthogonal onto the fiber optic bundle 120. The laser beam source 140 and the fiber optic bundle 120 are connected interiorly to the device housing 100 by the fiber optic housing 130 whereby the laser plane 160 is allowed to exit through a slot 150 for alignment of the archery bow. A switch 102 activates and deactivates the laser plane 160 by connecting a power source such as at least one battery (not shown) to the laser beam source 140.

In some embodiments, referring back to FIG. 2, the method for using the laser plane alignment device 90 on the archery bow 10 is to first install the laser plane alignment device 90 onto the archery bow 10 by placing the nock 110 onto the bowstring 40 and sitting the device housing 100 on the arrow rest 60, like how a typical arrow sits on a bow. The laser beam source 140 shown in FIG. 3 and FIG. 4 is then activated by the switch 102 producing the laser plane 160. The laser plane 160 is aligned with the bowstring 40 by rotating the device housing 100 about the long axis of the adapter 110 until the laser plane 160 is inline with the bowstring 40. While the laser plane 160 is still activated and aligned with the bowstring 40, the arrow rest 60 is adjusted left or right while the laser plane alignment device 90 is still sitting on the rest, until the laser plane 160 is aligned with the wheel or cam 30. When moving the arrow rest 60 left or right with the laser plane alignment device 90 sitting on the arrow rest 60, the laser plane 160 does not translate left or right but rotates about the long axis of the bowstring 40 while maintaining alignment of the laser plane 160 with the bowstring 40. With the laser plane 160 aligned to the bowstring 40 and the upper wheel or cam 30, now the sight 80, the upper flexible limb 20, the lower flexible limb 22, the lower wheel or cam 32 and the rest 60 or any other bow accessory can be aligned to the same laser plane 160.
