All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims.

(10) The terms a and an herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.

(11) 1. Detailed Description of the Figures

(12) Referring now to FIG. 1, a perspective view of the nunchucks 10 with visual and performance enhancements, according to the preferred embodiment of the present invention is disclosed. The nunchucks 10 (herein also described as the device) 10, includes two (2) sticks 15 connected together via a tether 20. In a preferred embodiment, the sticks 15 are manufactured from metal tubing that is durable and possesses high strength properties. Aluminum or titanium are envisioned as possible materials of construction for the stick 15 although other metal and non-metal materials are also envisioned. As such, the materials of construction used in the stick 15 as well as the entire device 10 are not envisioned to be a limiting factor of the present invention. It is also noted that the overall dimension of the stick 15 as well as the length of the tether 20 are also widely variable depending on the specific needs of the user, and as such, are also not a limiting factor of the present invention.

(13) Referring now more closely to FIG. 1, each stick 15 is defined as possessing a lower handle region 12 and an upper handle region 13. The distal end of the lower stick region 12 is open and capable of being plugged with an end cap 55. A lower band 16 circumscribes the outer perimeter of the stick 12 and overlaps the outer perimeter of the end plug 55. The lower band 16c is capable of attachment or removal and helps to keep the end plug 55 inserted into the open end of the lower handle region 12 of the stick 15. An intermediate band 16b is similarly constructed and removably placed on the stick 12. The location of the intermediate band 16b delineates the stick into the lower handle region 12 and upper handle region 13. The lower handle region 12 is envisioned to be seven to seven-and-a-half inches (7-7 in.) in length and the upper handle region 12 is envisioned to be four to four-and-a-half inches (4-4 in.) in length. The upper handle region 13 is sized to at least enable a final user to grip the stick 10.

(14) Within the proximal end of the upper handle region 13 of each stick 15 as viewed in FIG. 1 has a sealed bearing assembly 25 which is the joining mechanism between the stick 15 and the tether 20. An upper band 16a is located at this section to aid in restricting detritus or foreign objects from entering the sealed bearing assembly 20 and hindering operation thereof. The sealed bearing assembly 25 allows for smooth quiet rotation of the tether 20 in a three-hundred-sixty-degree (360) arc. Further description of the sealed bearing assemblies 25 will be provided here in below. The tether 20 is depicted as a heavy-duty nylon cable for purposes of illustration. Other types and styles of tether 20, including but not limited to: rope, wire, chain, and the like may be used with equal effectiveness. As such, the exact configuration of the tether 20 is not intended to be a limiting factor of the present invention.

(15) In the preferred embodiment, a set of through-cut graphical elements 35 is provided along a length of the lower handle region 12, adjacent to the location of the lower band 16c. The through-cut graphical elements 35 is cut completely through the tubing wall 40, such that it exposes the interior cavity 45 (not shown due to illustrative limitations of the sticks 15. The through-cut graphical elements 35 preferably comprise text (as shown) in various fonts, numbers, and/or graphical designs such as logos, design elements, pictures, caricatures, or any indicia the like. The open nature of the through-cut graphical elements 35 allows for the emanation of illumination 50. Further description on the origination of the illumination 50 will be provided herein below.

(16) Referring next to FIG. 2, a side view of one (1) of the sticks 15 as used with the preferred device 10 is depicted. It is noted that both sticks 15 are identical in construction. The stick 15, tether 20, and through-cut graphical elements 35 are identifiable as aforementioned described. The end plug 55 is removable in nature by the final user and is used to access the interior cavity 45 (not shown in this FIGURE) of the stick 15. The end plug 55 is manufactured from a pliable material, such as rubber. Further detail on the utilization of the end plug 55 will be provided herein below.

(17) Referring now to FIG. 3, a sectional view of the device 10, as seen along a line I-I, as shown in FIG. 1, according to the preferred embodiment of the present invention is shown. This view discloses the interior cavity 45 of an individual stick 15 and additional details on interior mounted components of the stick 15. A chemical light stick 60 is disposed within the interior cavity 45 and is placed by the final user via removal of the end plug 55. The chemical light stick 60 is a self-contained, short-term light-source having a translucent plastic tube containing isolated substances that, when combined, produce light through chemiluminescence. The chemical light stick 60 is well known in the art and its individual components are not within the scope of the present invention. The chemical light stick 60 may be made in multiple colors, sizes and styles.

(18) FIG. 6 illustrates the relationship between the end plug 55 and chemical light stick 60. A retaining strap 65, either an integral molded part of the chemical light stick 60, or a separate component that is physically attached to the end plug 55, is inserted through an aperture 70 provided in the center axial position of the end plug 55. The end plug 55 is held in place using a set of friction fit holding rings 75 which grip the interior cavity 45. A stopper 57 is placed over the opposing end of the chemical light stick 60 as a cap. The stopper 57 has a domed receiver and a pair of fins that are diametrically opposed and extend outward from the domed receiver. The end plug 55 along with the chemical light stick 60 is removed and inserted by applying physical force along a travel path f 80. The fins of the stopper 57 engage the interior of the stick 15 and prevent unintended removal of the chemical light stick 60 from the end plug 55 when the nunchucks 10 are used. Once activated, the chemical light stick 60 produces illumination 50 which emanate through the through-cut graphical elements 35 to produce a visual effect on the exterior of the stick 15.

(19) The tether 20 is retained within a center bearing face 85 of the sealed bearing assembly 25 with the aid of a retention device 90 such as a crimp (as shown), a knot, heat fusion, a fastener, or the like. The sealed bearing assembly 25 is preferably an external seal face 95 (visible as seen in FIG. 1) along with an internal seal face 100. The external race 105 of the sealed bearing assembly 25 is secured within the interior cavity 45 of the stick 15 that is pressure-pressed in place using a well-known process. A set of ball bearings 110 provide minimal friction between the stick 15 and tether 20 to allow for easy movement along the rotational travel path a 30 (as shown in FIG. 1).

(20) Referring to FIG. 4, a sectional view of the device 10, as seen along a line II-II, as shown in FIG. 2, according to the preferred embodiment of the present invention is disclosed. The tether 20 is located at the center of the assembly with the internal seal face 100 immediately adjacent. The ball bearings 110 provide reduced friction and may or may not be lubricated. The internal seal face 100 contains the ball bearings 110 along their exterior. The tubing wall 40 is visible as the outermost layer.

(21) Referring now to the alternate nunchuck embodiment 11, which is illustrated in FIG. 5. Each stick 15 is manufactured out of a transparent or translucent material, such as acrylic or a cross-linked polyethylene (PEX) material. The alternate nunchuck embodiment 11 has an overall size and shape similar to that of the preferred device 10, wherein the upper handle region 13, and lower handle region 12 are similarly configured. The alternate embodiment 11 also possesses the aforementioned description of the tether 20, sealed bearing assembly 25, end plug 55, and chemical light stick 60 providing the illumination 50.

(22) Located in a similar location and configured in a similar manner as the through-cut graphical elements 35 of the preferred device 10 are decals 36 capable of adhering to the exterior surface of the stick 15. The illumination 50 produced by the chemical light stick 60 emanates through the transparent or translucent properties of the alternate nunchuck embodiment 11.

(23) The upper band 16a, intermediate band 16b, and lower band 16c may be a resilient elastic material or a heat shrink wrap and is intended to aid in gripping the nunchucks 10, 11 but not interfering with the operation thereof. Such a thickness of the bands 16a, 16b, 16c is preferably seven-eighths to one inch (-1 in.).

(24) 2. Operation of the Preferred Embodiment

(25) The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. It is envisioned that the device 10 would be constructed in general accordance with FIG. 1 through FIGS. 4 and 6, with the alternate nunchuck embodiment 11 depicted most clearly in FIG. 5. The user would procure either device 10, 11 via conventional procurement channels such as martial art studios, sporting good stores, mail order or internet supply houses and the like. Special attention would be paid to construction specifics such as overall length of the sticks 15 and the tether 20, diameter of the tether 20, color, style, specific through-cut graphical elements 35, bands 16a, 16b, 16c, illumination 50, and the like.

(26) After procurement and prior to utilization, either device 10, 11 would be prepared in the following manner: the user would remove the end plug 55 from each stick 15 by applying opposing hand pressure along the travel path f 80; two (2) chemical light sticks 60 of the user's color choice would be activated using the activation process associated with the specific chemical light stick 60; an individual chemical light stick 60 would be secured within the aperture 70 of an individual end plug 55; said chemical light stick 60 and end plug 55 would be reinserted into each stick 15 by applying hand pressure along the travel path f 80. It is also noted that either device 10, 11 may be used without the insertion of the chemical light sticks 60 as aforementioned described. At this point in time either device 10, 11 would be ready for use.

(27) During utilization of either device 10, 11 the following procedure would be initiated: as the internal seal face 100 are manipulated using practice and skill, the user is rewarded with fast and quiet motion due the reduced friction nature of the sealed bearing assemblies 25. Additionally, during nighttime or low light use, the user or any nearby viewers are rewarded with an eye-catching display of illumination 50 that move through arcs in a visually stunning effect. As the materials of construction used with either device 10, 11 are virtually indestructible under normal use, the user is free to hit or otherwise almost any surface without worry of damage the device 10 nor stoppage of the illumination 50 due to its chemical nature.

(28) After use of either device 10, 11, the chemical light sticks 60 may be removed and discarded thus readying either device 10, 11 for future usage cycles as described above in a cyclical process.
