No. 61/729,901, filed Nov. 26, 2012, and entitled, “Universal Lighted Nock And Processes Therefor;” U.S. provisional patent application Ser. No. 61/749,050, filed Jan. 4, 2013, and entitled, “Vane For Bolts, Arrows, And The Like;” and U.S. provisional patent application Ser. No. 61/749,262, filed Jan. 5, 2013, and entitled, “Lighted Nock Activation Means And Processes Therefor;” the disclosures of each being incorporated by reference herein.


TECHNICAL FIELD
The present invention relates, generally, to nocks for use with arrows, cross-bow bolts, and the like; and, more particularly, to lighted nocks for use therewith.
BACKGROUND
In archery, it is well-known that a nock is associated with the rearmost portion of an arrow, cross-bow bolt, and the like. A bowstring fits into the nock and propels the arrow from the bow upon release. With the advent of translucent plastic nocks, along with the advent of small-profile light emitting diode (“LED”) and battery assemblies, it was recognized that the tail portion of an arrow could be lighted by fitting an LED/battery assembly within the translucent nock. It was recognized, advantageously, that such a lighted nock could provide a means to track arrow flight and targeting, such as may be useful at night, in low light conditions, or in poor visibility situations.
U.S. Pat. No. 4,340,930, issued Jul. 20, 1982 to Carissimi, and U.S. Patent Application Publication U.S. 2012/0100942 by Minica, published Apr. 26, 2012, provide examples of such products. Disadvantageously, such products typically are formed in integral units, wherein a user cannot substitute a nock or an LED/battery assembly of his own choosing. Rather, a user is captive to a particular manufacturer's device construction, nock and LED color selections, and product availability. Additionally, due to the sealed and/or closed nature of such devices, switching off the LED/battery assembly after activation can sometimes be difficult and can tax one's dexterity—especially in field-use conditions.
It would be preferable to provide a user with a lighted nock configuration that provides a more universal construction, whereby a user conveniently may gain access to the working components, whereby those components may be transferred to other arrows, whereby the user may substitute nocks and LED/battery assemblies of his choice, and whereby the user can more easily access the LED/battery assembly to activate and deactivate the assembly without undue difficulty—all in field-use conditions.
It is to the disclosure of such devices and related processes of use that the following is directed.
SUMMARY
In general, the present disclosure is directed to lighted nocks for use with arrows, cross-bow bolts, and the like. Specifically, and pursuant to a preferred embodiment of the present disclosure, a cap is provided that fits within the tail end of a standard tubular arrow shaft. At its front end, the cap comprises a shoulder to bear against the tail end of the tubular arrow shaft, and a face to bear against the shoulder of a nock.
The cap further comprises a recess therewithin, terminating in a floor portion at its tail end. An LED/battery assembly fits within the recess of the cap, the tail end of the LED/battery assembly abutting the floor portion of the cap. The tail end of a nock fits over the LED/battery assembly and into the recess of the cap.
In ready-to-fire position, the LED/battery assembly is in deactivated position, comprising an activation gap between the LED lamp and the body of the battery assembly. A corresponding gap, greater than or equal to the activation gap, is left between the shoulder of the nock and the face of the cap.
When fired, the bow string drives an internal surface of the nock into the front end of the LED/battery assembly. Because the tail end of the LED/battery assembly is in contact with the floor portion of the cap, the driving force of the nock acts to close the activation gap; thereby, illuminating the LED lamp.
To reset the assembly for firing anew, one simply removes the nock and resets the LED/battery assembly to its deactivated position, which is done by pulling the LED lamp to reopen the activation gap. One then places the LED/battery assembly and nock into their ready-to-fire position within the cap, leaving a gap as described above.
Accordingly, and advantageously, the subject matter of the present disclosure provides a user with a lighted nock configuration that provides a more universal construction than has heretofore been developed in the known prior art, whereby a user conveniently may gain access to the working components, whereby those components may be transferred to other arrows, whereby the user may substitute nocks and LED/battery assemblies of his choice, and whereby the user can more easily access the LED/battery assembly to activate and deactivate the assembly without undue difficulty—all in field-use conditions.
These and other features and advantages of the various embodiments of devices and related systems comprising, as set forth within the present disclosure, will become more apparent to those of ordinary skill in the art after reading the following Detailed Description of Illustrative Embodiments and the Claims in light of the accompanying drawing Figures.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
In describing the several embodiments illustrated in the Figures, specific terminology is employed for the sake of clarity. The invention, however, is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose. Additionally, in the Figures, like reference numerals shall be used to designate corresponding parts throughout the several Figures.
Illustrated in FIGS. 1-3 is a preferred embodiment of lighted nock 10 for use with arrows, cross-bow bolts, and the like, according to the subject matter of the present disclosure. With reference to FIG. 1, conventional, tubular arrow shaft 20 comprises tail end 30. To arrow shaft 20 is typically attached three fletch members 40, the fletch members used to stabilize the arrow during flight.
In order to prepare an arrow to receive lighted nock 10 of the present disclosure, one removes any prefitted nock from tail end 30. In lieu thereof, cap 50 fits within tail end 30 of tubular arrow shaft 20. At its front end 60, cap 50 comprises shoulder 70 to bear against tail end 30 of tubular arrow shaft 20, and face 80 to bear against shoulder 90 of nock 100. In some embodiments, cap 50 is constructed of aluminum; however, any material may be used that would be suitable to the intended applications and uses described herein. It is noted that, for a secure fit, a user optionally may bond cap 50 into tail end 30 of tubular arrow shaft 20 by use of any suitable adhesive.
Cap 50 further comprises recess 110 therewithin, terminating in floor portion 120 at tail end 130. LED/battery assembly 140 (shown in FIG. 1 both in an open, deactivated configuration 140′ and a closed, activated configuration 140′′) fits within recess 110 of cap 50, tail end 150 of LED/battery assembly 140 abutting floor portion 120 of cap 50. In most circumstances, it is preferred that LED/battery assembly initially be in open, deactivated configuration 140′, so that the user's night vision is not interrupted by the brightly illuminated LED lamp 170, and so that a user's field position remains concealed prior to firing.
In ready-to-fire position, best seen with reference to FIG. 2, tail end 160 of nock 100 fits over LED/battery assembly 140 and into recess 110 of cap 50. As described above, LED/battery assembly 140 preferably remains in deactivated position 140′, comprising activation gap GA between the LED lamp 170 and body 180 of battery assembly 190. A corresponding firing gap GF, greater than or equal to activation gap GA, is left between shoulder 90 of nock 100 and face 80 of cap 50.
Best seen with reference to FIG. 3, when the arrow, so configured, is fired, bow string S drives internal surface 200 of nock 100 into front end 210 of LED/battery assembly 140. Because tail end 150 of LED/battery assembly 140 is in contact with floor portion 120 of the recess 110 of the cap 50, the driving force of nock 100 acts to compress the LED/battery assembly 140 against the floor portion 120 of the cap recess 110 to close firing gap GF, and, in turn, activation gap GA; thereby, illuminating LED lamp 170.
To reset lighted nock 10 for firing anew, one simply removes nock 100 and resets LED/battery assembly 140, which is removably disposed within the recess of the nock 100, to its deactivated position 140′, which is done by pulling the LED lamp to reopen activation gap GA. One then places LED/battery assembly 140 and nock 100 into their ready-to-fire position within cap 50, leaving firing gap GF as described above.
It is noted that, in some embodiments, LED/battery assembly 140 may comprise an LED with built-in, pin type lithium battery, such as the JNJ R-type assembly (JNJ Co., LTd., Korea). Suitably configured; however, lighted nock 10 may be used in association with any of a variety of LED/battery assemblies currently on the market.
Turning now to FIG. 4, the above-described steps for configuring and firing an arrow carrying a lighted nock in accordance with the present disclosure are outlined in process flowchart form. At step 400, one inserts a shouldered cap, such as, for example, cap 50, into the tail end of a tubular arrow shaft. At step 410, one inserts a deactivated LED/battery assembly, such as, for example, LED/battery assembly 140, into a recess within the cap. The tail end of the LED/battery assembly should abut a floor portion within the cap.
At step 420, a nock, such as, for example, nock 100, is inserted over the deactivated LED/battery assembly and into the recess of the cap. A firing gap greater than or equal to the activation gap of the LED/battery assembly should be maintained.
At step 430, the arrow, configured as described above, is nocked onto the bowstring. At step 440, the bowstring is drawn and released, driving the nock into the LED/battery assembly; thereby, closing the firing gap and the activation gap, and illuminating the LED lamp.
Referring now to FIG. 5, the above-described steps for resetting and readying for refiring an arrow carrying a lighted nock in accordance with the present disclosure are outlined in process flowchart form. At step 500, the nock is removed. At step 510, the LED/battery assembly is reset to a deactivated condition by opening the activation gap. At this point, one may ready the lighted nock for refiring by returning to the process of FIG. 4, step 410.
Having thus described exemplary embodiments of the subject matter of the present disclosure, it is noted that the within disclosures are exemplary only and that various other alternatives, adaptations, and modifications may be made within the scope and spirit of the present invention. For example, while the disclosure set forth hereinabove has been provided with reference to conventional arrows, the subject matter could be extended to use in association with bolts for use in association with cross-bows, or the like, without limitation.
Furthermore, the subject matter of the present disclosure may be utilized in association with target practice, situational shooting, and/or the like, as well as with hunting and other in-field uses.
In some embodiments, the subject matter of the present disclosure may be provided in packaged form comprising one or more suitably configured nock, LED/battery assembly, and cap. In such form, a user may utilize his own arrow in association with the subject matter of the present disclosure
In some embodiments, the subject matter of the present disclosure may be provided in packaged form comprising one or more, optionally pre-fletched, arrow, along with one or more suitably configured nock, LED/battery assembly, and cap.
